[1028] Example embodiments of the invention will be described with reference to the accompanying drawings.

[1029] The device of the present inventiongenerally shown as 200 in FIG. 7comprises a receiving component for receiving and holding a receptacle and a cleaning component that is extendable into at least a part of the interior of the receptacle when the receptacle is placed on the receiving component. The receiving component of the device is illustrated in FIGS. 2-6 and 8-11. Further elements thereof may be seen in FIG. 7. The cleaning component of the device is illustrated in FIG. 1. A preferred embodiment of the rotation driving component is illustrated in FIG. 9. In the Figures the receptacle is presented as receptacle 80, which is not part of the device as such but is shown for ease of understanding of the present invention. The receptacle 80 is open-ended at one end 81 and has an inner wall 83 and an inner base that defines an inner space 82.

[1030] Referring to FIG. 1 the cleaning medium generating system 1 of the cleaning component of the device comprises a system that generates steam that is used to clean the interior of a receptacle (not shown in FIG. 1). The cleaning medium generating system 1 comprises a water source 10 operably connected to a hose 20 that is operably connected to a water pump 30. Water pump 30 is operably connected to a water heater 40 that is operably connected to a pressure sensor 50. Pressure sensor 50 is operably connected to a valve 60 that is operably connected to the rotary washing bay 100 of the receiving component of the device (not shown in FIG. 1).

[1031] Also referring to FIG. 1 the cleaning medium generating system 1 comprises an electronic control box 70 that is operably connected to each of the water pump 30, the water heater 40, the pressure sensor 50 and the valve 60such as by means of electrical leads or cables (not shown in FIG. 1).

[1032] The device of the present invention has generally two separate cycles in normal usagenamely a standby cycle and an operating cycle.

[1033] In the case of the standby cycle: the valve 60 is closed, the pump 30 delivers water from the water source 10 through the water heater 40 and pressure sensor 50. When a sufficient body of water is in the water heater 40 and the pressure sensor 50, the pump 30 turns off and encloses said body of water in the channel comprising the water heater 40 and pressure sensor 50. Upon the pump 30 turning off, the water heater 40 turns on. This action causes the body of water in said channel to vaporise and increase the pressure in the channel comprising of the water heater 40 and pressure sensor 50. The pressure sensor 50 relays the measured pressure value of said channel to the electronic control box 70. The electronic control box 70 receives this value and compares it against a preconfigured standby pressure value. If the pressure sensor 50 value exceeds the preconfigured standby pressure value, the electronic control box 70 signals to the water heater 40 to turn off. The pressure within said channel of water heater 40 and pressure sensor 50 will then fall. Once the pressure sensor 50 returns a value that does not exceed the preconfigured standby pressure value, the water heater 40 will turn on again. This cycle continues indefinitely until the cleaning medium generating system 1 is either turned off or the user initiates the operating cycle.

[1034] Referring to FIG. 2 the rotary washing bay 100 of the receiving component of the device comprises a system that rotates a rotary assembly about a stationary assembly. The rotary assembly comprises first rotating element 90, shown as an upper turntable, which operably connects to a second rotating element 130, shown as a lower turntable. The stationary assembly comprises a base plate 140, which operably connects to a drain module 97 and a shaft 120 (connection not shown). Cleaning elementshown as a nozzle 110operably connects to the shaft 120.

[1035] The first rotating element 90 is shown as an upper turntable. This upper turntable is an example of a first rotating element that is capable of rotating the receptacle. The second rotating element 130 is shown as a lower turntable. This lower turntable is an example of a second rotating element capable of driving rotation of the first rotating element. The nozzle 110 is an example of a cleaning element. The drain module 97 is an example of a basin element. The drain outlet 95 is an example of a drain outlet for removal of spent cleaning medium.

[1036] Referring to FIGS. 2 and 3, in use a receptacle, such as a beverage vessel 80, is shown to be placed into device 100. The beverage vessel 80 is placed into the receiving component, onto the first rotating element 90, shown as an upper turntable, and becomes operably connected.

[1037] Referring to FIG. 4, the device 100 can be seen without the placement of the beverage vessel.

[1038] Referring to FIG. 5, the rotary assembly comprises the first rotating element 90 shown as an upper turntable, which is part of the receiving component, and second rotating element 130 shown as a lower turntable. In use, the first rotating element 90 and the second rotating element 130 are rotationally driven about a bearing 195 on the stationary shaft 120 by an electric motor 150, a worm gear 170 and ring gear 160.

[1039] The gear attached to second rotating element 160 is an example of a driven gear. The worm gear 170 is an example of a drive gear. The electric motor 150 fitted with the worm gear 170 is an example of a means for driving the rotation of the second rotation element.

[1040] Referring to FIG. 6, the rotary washing bay 100 comprises a delivery hose which is operably connected to the nozzle 110 through which fluid can be delivered from device 1. The receptacle 80 is at least partly open-ended at one end 81 and having an interior space 82 defined by an interior wall 83. As can be seen from FIG. 6 the cleaning element nozzle 110 is located in the interior space 82 of the receptacle 80. The cleaning element nozzle 110 is configured to face all of the surface of at least a part of the interior wall 83 of the receptacle 80 on rotation of the receptacle 80 about its central axis by turntable 90thereby allowing the cleaning thereof by the cleaning medium such as steam (not shown) that exits the end of the cleaning element nozzle 110.

[1041] Referring to FIG. 7, the device 200 comprises: the main body enclosure 230 which operably connects to a lid 210 which operably connects to the human user interface module 220. The cleaning medium generating system 1 and the rotary washing bay 100 are both enclosed in the casing 200.

[1042] In the case of the operating cycle, the user (not shown) will place the beverage vessel 80 into device 200, on top of the first rotating element 90, shown as an upper turntable, in the rotary washing bay 100. The user will then close the lid 210, enclosing the beverage vessel 80 within the device 200. Then the user will initiate the operating cycle by means of the human interface module 220. Upon this, the human interface module 220 sends a signal to the electronic control box 70.

[1043] The electronic control box 70 compares the current value of the pressure sensor 50 to the preconfigured operating pressure value. If the pressure sensor 50 value is lower than the preconfigured operating pressure value, the electronic control box 70 signals to the water heater 40 to turn on. Once the pressure sensor 50 value equals or exceeds the preconfigured operating pressure value, the control box 70 sends a signal simultaneously to the water pump 30 and the valve 60. The water pump 30 will turn on and the valve 60 will open. Water from the water source 10 will now be pumped constantly through the water heater 40 and vaporise to steam. This vaporised fluid continues through the now open valve 60 to the delivery hose 180, also shown in the rotary washing bay 100.

[1044] The flow of vaporised fluid travels through the delivery hose 180 to the nozzle 110 and exits the rotary washing bay 100 at high speed. The flow of vaporised fluid proceeds to remove residue from the internal face of the beverage vessel 80.

[1045] At the point the valve 60 is opened and the pump 30 is turned on, the electronic control box 70 turns on the electric motor 150. The electric motor 150 drives the worm gear 170, ring gear 160, second rotating element 130 (shown as an lower turntable), first rotating element 90 (shown as an upper turntable), and beverage vessel 80. The rotation of the beverage vessel 80 above the nozzle 110 allows the flow of vaporised fluid to remove residue from the complete circumference of the internal face of the beverage vessel 80.

[1046] The condensed waste liquid will exit the rotary washing bay 100 through the drain outlet 95 to waste collection external of the device 200 (not shown).

[1047] After a preconfigured duration, the electronic control box 70 sends a signal simultaneously to the pump 30, the water heater 40, the valve 60 and electric motor 150. The pump 30, the water heater 40 and the electric motor 150 will now turn off and the valve 60 will close. Following this the flow of vaporised fluid from the cleaning medium generating system 1 halts to the rotary washing bay 100.

[1048] Upon the halting of the flow of vaporised fluid, the user is now informed via the human user interface module 220 to open the lid 210 and remove the cleaned beverage vessel 80. This marks the end of the operating cycle. Following the end of the operating cycle, the cleaning medium generating system 1 will automatically return to the standby cycle until the next operating cycle is initiated or until the current invention is switched off.

[1049] Periodically, the human user interface module 220 will alert the user that maintenance is required. Maintenance can include the removal of the first rotating element 90, shown as an upper turntable, and drain module 97 for the user to clean externally of device 200 (not shown). The first rotating element 90 and drain module 97 can both be removed with ease from device 200. The use of seals (not shown) ensure the water tightness of the rotary washing bay 100 when the first rotating element 90 and drain module 97 are returned to the rotary washing bay 100 in preparation for normal usage.

[1050] FIG. 8 illustrates the receiving component and rotation driving component of a preferred embodiment of the device. The device comprises a first rotating element 90, shown as an upper turntable. The first rotating element 90, shown as an upper turntable, comprises an array of magnets 315 that are sunk into first rotating element 90. The first rotating element 90, shown as an upper turntable, is magnetically coupled to the rotation driving component 400. The receiving component further comprises a basin element 320 and a drain outlet 95. In use, the basin element 320 is capable of capturing and retaining spent cleaning medium until it drains from the basin element 320 via the drain outlet 95. As can be seen from FIG. 8, the first rotating element 90 is located within the basin element 320. The first rotating element 90, shown as an upper turntable, is able to rotate within the basin element 320 and may be removed with ease from the device by overcoming the magnetic coupling between the first rotating element 90 and the rotation driving component 400. The rotation driving component 400 is located outside of the basin element 320.

[1051] The first rotating element 90 is shown as an upper turntable. This upper turntable is an example of a first rotating element that is capable of rotating the receptacle. The basin element 320 is an example of a basin element that is capable of capturing spent cleaning medium. The drain outlet 95 is an example of a drain outlet for removal of spent cleaning medium.

[1052] Referring to FIG. 9, in a preferred embodiment the rotation driving component 400 comprises an electric motor 150, a gear attached to the motor 410, a gear attached to second rotating element 160, a bearing 195, a second rotating element 130, an array of magnets 460 and gearbox housing 470. The gear attached to the motor 410, the gear attached to second rotating element 160, the bearing 195, the second rotating element 130, and the array of magnets 460 are all located within the gearbox housing 470. The electric motor 150 is capable of rotating the gear attached to the motor 410. The gear attached to the motor 410 is operably attached to gear attached to second rotating element 160. The gear attached to the motor 410 is configured to cause rotation of gear attached to second rotating element 160 on rotation of the gear attached to the motor 410. The array of magnets 460 are mounted on the second rotating element 130. The second rotating element 130, together the array of magnets 460 mounted thereon, rotates with gear attached to second rotating element 160. Both the second rotating element 130 and gear attached to second rotating element 160 are attached to inner race of the bearing 195. The array of magnets 460 comprised in the rotation driving component 400 correspond (are of opposing polarity) to the array of magnets 315 (not shown in this figure) that are sunk into first rotating element 90 (not shown in this figure). The arrays of opposing magnets 315 (not shown in this figure), 460 are configured to cause the first rotating element 90 (not shown in this figure) to be magnetically coupled to the second rotating element 130. The arrays of opposing magnets 315 (not shown in this figure), 460 are configured to cause rotation of the first rotating element 90 on rotation of the second rotating element 130.

[1053] The second rotating element 130 is an example of second rotating element that is capable of driving rotation of the first rotating element. The arrays of opposing magnets 315, 460 are an example of a magnetic coupling. The gear attached to second rotating element 160 is an example of a driven gear. The gear attached to the motor 410 is an example of a drive gear. The electric motor 150 fitted with the gear 410 is an example of a means for driving the rotation of the second rotation element.

[1054] Referring to FIGS. 10 and 11, the first rotating element 90, shown as an upper turntable, is mounted on a shelf 325 that offsets from the wall and base of the basin element 320. The cleaning element 110 in located within the basin element 320 and extends beyond the basin element 320 and the first rotating element 90. In use, the first rotating element 90, shown as an upper turntable, within the basin element 320 supports the receptacle 80 placed by the user.

[1055] As can be seen from FIG. 10, the cleaning element nozzle 110 is located so as it will be positioned within the interior space of a receptacle 80 in use of the specific device shown. The receptacle 80 is rotated about its central axis by first rotating element 90, shown as an upper turntable, thereby allowing the cleaning element nozzle 110 to face all of the surface of at least a part of the interior wall 83 of the receptacle 80-thereby allowing the cleaning thereof by the cleaning medium such as steam (not shown) that exits the end of the cleaning element nozzle 110.

[1056] FIG. 12A presents a view of the device 200 where a coaxial arrangement of the magnets providing the magnetic coupling between the first rotating element 90 and the second rotating element 130 is employed. As illustrated in FIG. 12A, the device 200 has a basin element 320. As discussed above, the electric motor 150 drives a gear 410 which is mechanically connected to a gear 160 of the second rotating element 130. Rotation of the electric motor 150 therefore effects rotation of the gears 410, 160 and consequently the second rotating element 130.

[1057] FIG. 12B shows a more detailed view of the device of FIG. 12A with the front-most section removed so that the magnetic coupling can be seen. As shown in FIG. 12B, the first rotating element 90 (here the turntable) is provided with a series of magnets 315 arranged at intervals around the circumference of the turntable 90. Disposed coaxially with respect to these magnets 315, the second rotating element 130 is provided with a set of magnets 415 at a greater radial displacement from the axis of rotation of the turntable 90. In this sense, the two sets are offset from each other in a horizontal plane (i.e., perpendicular to the axis of rotation).

[1058] FIG. 13 presents a cross-sectional view of the device 200 with the coaxial arrangement of magnets. In this view, it can again be seen that the two sets of magnets 315, 460 are offset from each other in a horizontal plane (i.e., coaxially). This allows the vertical height of the coupling region to be reduced since vertical space does not need to be provided to accommodate both sets of magnets one above the other.

[1059] FIG. 14 presents an expanded view of the device 200 according to the embodiment employing the coaxial arrangement of magnets. As shown in FIG. 14, the turntable 90 is provided with a set of magnets 315 that oppose a set of magnets 460 positioned in the second rotating element 130 to form a magnetic coupling. The first and second rotating elements are arranged within a basin element 320. The second rotating element 130 is connected to a bearing 195 which permits rotation of the first and second rotating elements (and a receptacle) with respect to the rest of the device 200. An electric motor 150 is provided to drive rotation the gears 410, 160 so as to rotate the second rotating element 130 and drive rotation of the first rotating element 90.

[1060] FIG. 15 presents a cross-sectional view of the device 200 according to the embodiment employing the coaxial arrangement of magnets. As shown in FIG. 15, the basin element 320 comprises a basin shelf 322 (also referred to as a support element) on which the turntable 90 is supported. The second rotating element 130, incorporating the set of magnets 460 is disposed outside the basin element 320 in a radial direction. Since the basin shelf 322 does not need to support the two sets of magnets being positioned with an offset in the axial (vertical) direction, a small basin shelf 322 can be used. This simplifies the design of the device, improves drainage and reduces the risk of blockages.

[1061] FIGS. 16 to 20 illustrate one or more of the following features of the device: [1062] (a) a gutter for removal of condensation that may occur through use of the device; and/or [1063] (b) a control unit that is responsive to user input to operate the device; and/or [1064] (c) a surface that is substantially flush with a surface on or in which the device is mounted and/or wherein the device comprises a fluid path for removal of fluid during use of after use of the device; and/or [1065] (d) a removable lid; and/or [1066] (e) at least all or part of the device is contained within at least one housing.

[1067] In these embodiments, a housing 500 contains the device. The housing 500 has a housing unit 520. The housing until 520 can have an upper surface 600 and a lower part 620. In this design, the device includes a lid 550 and a lid receiving structure 700. When lowered to be within the lid receiving structure 700, the device lid 550 and the lid receiving structure 700 are substantially flush with the upper surface 600 thereby enabling the device to be easily cleaned. The lid receiving structure 700 releasably receives the lid 550 and in such a manner that there is no or very little degree of fluid egress between the lid receiving structure 700 and the lid 550 during use of the device.

[1068] The lid receiving structure 700 comprises an aperture 730 defined by surround 720. Aperture 730 releasably and snuggly accommodates the lid 550. Lid 550 has a surround portion 820 that defines an aperture into which is releasably mounted a glass cover 840. The glass cover 840 is removable for ease of cleaning and can be replaced.

[1069] The lid receiving structure 700 houses three user interface buttons. User interface button (A) 740 informs allows the user to cycle backwards and forwards throughout the program cycle. User interface button (B) 760 informs the user for the next steps when using the device. User interface button (C) 780 allows the user to operate the device.

[1070] The lid 550 is releasably mounted in recess 925 to form a snug fit. Recess 925 has a configuration to allow flow of liquid to the inner chamber.

[1071] The lid receiving structure 700 and the lid 550 are connected by means of a hinge 890. Hinge 890 has a gutter 900 along which any condensed water may flow when the lid 550 has opened. The water flows along gutter 900 into the chamber 950.

[1072] Chamber 950 has a gutter 970 that can act as a support for hinge 890.

[1073] In use, following steps are undertaken: [1074] 1. User presses button 780 [1075] 2. Lid component 700 and lid component 800 open [1076] 3. User is prompted to place receptaclefor example a cupin the chamber 950 by means of a display on button 760 [1077] 4. User places receptacle-for example a cup in the chamber 950 [1078] 5. User shuts lid component 700 and lid component 800 [1079] 6. User presses button 780 [1080] 7. The device then undergoes 1 or more wash cycles [1081] 8. Lid component 700 and lid component 800 open at end of the cycle(s) [1082] 9. User is prompted to remove receptacle-for example a cup-from the chamber 950 by means of a display on button 760 [1083] 10. User removes receptacle [1084] 11. User is prompted to shut the lid component 700 and lid component 800 by means of a display on button 760.

[1085] Features (a)-(e) are illustrated in more detail in FIGS. 21A-26B. While these features are described separately with respect to those figures, it should be appreciated that these features may be used in combination with each other. For example, the device arranged across a separate head unit and auxiliary unit as depicted in FIGS. 26A-26B may be mounted flush in or on a surface as described with respect to FIGS. 24A-24F and/or may have a removable/replaceable lid/top surface as described with respect to FIGS. 25A-25B. Further, these features may in some examples be implemented in a device which does not employ rotation of the receptacle. Instead, for example, these features may implemented in a device with a rotating nozzle in which the receptacle is kept stationary and/or in a device with a stationary nozzle and stationary receptacle.

[1086] FIGS. 21A-21D show an illustration of a device in which there is a gutter 900 arranged to channel fluid. In use, a receptacle washing cycle will be run with the lid 550 in a closed position so as to prevent the egress of the cleaning medium (e.g., steam or water) from the device. During the washing cycle therefore, fluid may build up on the bottom surface of the lid 550, for example in the form of the cleaning medium itself or condensation formed as a result of a steam cleaning medium being used. Unless directed elsewhere, when the lid 550 is later opened at the end of the receptacle washing cycle, the fluid may drain off the lid 550 and onto a top surface 700 of the device or a surrounding surface. This escaped fluid may then pool or flow across neighbouring surfaces.

[1087] In some examples, the lid comprises a glass cover 840 to enable a user to visually monitor the progress of the washing cycle. However, the use of such a glass cover 840 may encourage condensation of steam present within a chamber 950 of the device on the glass cover 840 and therefore exacerbate the above-described problem of fluid accumulating outside of the device.

[1088] FIG. 21A shows an example of a device in which a gutter 900 is provided to channel fluid from the lid 550 back into the chamber 950. This gutter 900 is shown in more detail in FIG. 21B. As illustrated, the lid 500 is connected to the rest of the device (e.g., a receiving component of the device) by a hinge 890 which allows the lid 550 to move between an open position (as illustrated in FIG. 21B) in which access to the chamber 950 is provided and a closed position (as illustrated in FIG. 24B) in which a receptacle can be enclosed in the chamber 950. Formed in the hinge 890 is a gutter 900. The gutter 900 is formed as a channel or groove within the hinge and is arranged such that water accumulating on the lid 550 is directed into the chamber 950 rather than allowing the fluid to drip off the lid 550 and onto a top surface 700 of the device.

[1089] The device shown in FIG. 21B has a glass cover 840 formed within a surround 820 of the lid 550 to allow a user to visually inspect the contents of the chamber 950. The surround 820 is shaped so as to provide a lip 850 which directs fluid from the glass cover 840 to a mouth of the gutter 900.

[1090] FIG. 21D shows a cross-section of the device, taken along the line A-A shown in FIG. 21C. FIG. 21D illustrates with arrows a fluid path provided by the device for channelling fluid from the lid 550 into the gutter 900 and from the gutter 900 into the chamber 950 of the device. By directing the fluid into the chamber 950 as shown, the device is able to reduce the amount of fluid accumulating outside of the device.

[1091] From the chamber 950, the fluid may be expelled via a drain 97, through a drain outlet 95 and expelled as waste.

[1092] FIG. 22 presents an illustration of a user interface of the device according to an example. As shown in FIG. 22, a top surface 700 of the device is provided with a user interface button (A) 740, a user interface button (C) 780, and a screen 790. It will be appreciated that other forms of user interface with more or fewer interface elements may also be used. However, in this example, only two user interface buttons, 740, 780 are provided, where user interface button (A) 740 corresponds to a selection button and user interface button (C) 780 corresponds to an action button. The screen 790 is provided to enable communication of a device state to the user and/or to present a currently selected receptacle washing cycle to the user. In this way, the user interface provides a simple and intuitive means to operate the device.

[1093] FIG. 23 is flowchart illustrating control flow of the device as implemented by a control unit of the device. As illustrated, the flow starts at step 2301 at which point the lid is in an initial closed position. When the action button is pressed at step 2303, flow proceeds to 2305 where the lid is opened. In some examples, the lid opens automatically (e.g., as a result of the device releasing a latch holding the lid closed and allowing a spring mechanism to open the lid). In some examples however, the control unit is responsive to the action button being pressed to unlock the lid to allow the user to open the lid. In this case, opening of the lid is performed by the user themselves.

[1094] With the lid in the open position, access is provided to the chamber 950 of the device to enable the user to place a receptacle to be cleaned inside the device.

[1095] A cycle selection menu is shown at step 2307 using the screen 790. The user is able to select a desired cycle using the selection button to iterate through available cycles and the action button to select a desired cycle as illustrated in blocks 2309, 2311, and 2313.

[1096] Once the action button has been pressed at step 2313 to select a cycle, the lid closes at step 2315. The lid may be closed by the user (e.g., in response to a prompt displayed via the screen 790) or in some examples, the device is provided with a lid closing mechanism and the lid is closed automatically on selection of a receptacle washing cycle. In either case, however, the selected cycle 2317 does not begin until the lid has closed in order to prevent cleaning fluid being expelled from the device.

[1097] In some examples, the lid may be closed in advance of either the cycle selection menu being shown at step 2307 or the selection of the cycle being made. In yet further examples, step 2313 in which the action button is pressed to confirm the user's selection and begin the cycle may be omitted and closing of the lid by the user at step 2315 may instead be taken as an indication to begin a washing cycle. In this case, closing of the lid by the user may represent a user input in response to which the cycle is initiated.

[1098] The selected cycle continues at step 2321 until either a cycle time duration has elapsed or until the user presses the action button to halt the cycle, as shown in step 2319. Once the cycle ends at step 2323, the lid opens at step 2325 to provide the user access to the cleaned receptacle. At this point, the user can retrieve their cleaned receptacle from the chamber 950 of the device.

[1099] At this point, the user's interaction with the device may conclude. The control unit may then initiate a self-clean cycle In some examples, the self-clean cycle is performed after each washing cycle; however, the self-clean cycle may be triggered after a predetermined number of cleaning cycles have been performed, in response to user input initiating the self-clean cycle, or in response to detecting that the device has not been used for a certain period of time.

[1100] Once the control unit has determined to perform the self-clean cycle at step 2327, the lid is closed at step 2329. Again, closing the lid may be performed automatically using a lid closing mechanism or the control unit may be configured to request that a user closes the lid (e.g., by displaying a message on the screen 790). The self-clean cycle then begins at 2331 and ends at step 2333. At this point, the device is again in its initial state.

[1101] With this approach therefore, the device requires only a single instance of user input to allow the lid to open from its closed position and only a single instance of user input to initiate the receptacle washing cycle. Thus, starting from the initial state the user can initiate the receptacle washing cycle using only two instances of user input. This approach therefore provides a simple interface allowing a user to quickly and intuitively control the device.

[1102] FIGS. 24A-24F present illustrations of a device mounted within a surface 990. The surface 990 may for example be a counter-top, table-top or bar-top. As shown in FIG. 24A, the device is mounted such that the top surface 700 of the device is flush with the top of the surface 990. By arranging the device in this way, the device can be cleaned easily. This is illustrated in FIGS. 24A and 24B in which a cup 980 that has spilled is depicted whereby the liquid has spilled across the device. With the device having a flat top surface that is flush with the surface in which the device is mounted, the entire top portion of the device (as shown in grey in FIG. 24B) can be wiped clean.

[1103] In some examples, to further aid cleaning of the device, a fluid path is provided that allows fluid to flow from the surface 990 into the chamber 950 of the device, even when the lid 550 is in a closed position. FIG. 24F shows an enlarged cross-section of the portion of the device indicated in FIG. 24E, the cross-section taken along the line B-B shown in FIG. 24D. The arrows in FIG. 24F show a fluid path from the surface 990 in which the device is mounted such that any fluid approaching the edge of the device where the lid 550 meets the lid receiving structure 700 may pass over a lip formed at this edge and into the chamber 950 of the device. Hence, any fluid on the top surface of the device or on the surface of 980 may be directed to the device and allowed to flow into the chamber 950 via the inner recess 925 allowing the surfaces to be cleaned more easily.

[1104] FIG. 25A shows an example implementation of the device in which the device (or a part thereof) is mounted in the top surface 990 of a cabinet 995. The cabinet 995 may be situated within a coffee shop environment, work environment, home environment or conference environment for example. As shown in in more detail in FIG. 25B, the device comprises a mounting assembly 710 which is mounted within the surface 990 (e.g., using screws, nails, or clips). To this mounting assembly 710 may be attached a top surface 700 which acts as a lid receiving structure in which the lid 550 fits when in the closed position to enclose the chamber 950. The top surface 700 and/or the lid 550 are attached removably to the mounting assembly 710. For example, the top surface 700 and/or the lid 550 may be connected to the mounting assembly 710 using one or more clips or screws, for example. Regardless of the particular form of removable mounting used, the top surface 700 and/or the lid 550 are arranged such that they can be easily removed from the mounting assembly 710 and replaced. The lid 550 and the top surface 700 are both exposed when in use and thus are more susceptible to damage. Additionally, any defects in those components are more noticeable are these components are visible to the user. It may therefore be desired to replace these components separately from the rest of the device in order to fix any such defects or as part of a regular maintenance schedule, such replacement being made more convenient by the use of the above-described removable attachment.

[1105] FIGS. 26A-26B show a device for cleaning a receptacle in which the device is arranged as a split system with a head unit 1005 including the components that the user interacts with and an auxiliary unit 1010 (which may be an under counter unit) containing at least a cleaning medium provision apparatus (e.g., a steam generation apparatus). By arranging the device as a split system in this way, the head unit 1005 can be situated separately from the auxiliary unit 1010 providing flexibility as to the arrangement of the device, especially where space for the device is constrained. As shown in FIG. 26A, the head unit 1005 may be arranged within a surface 990 of a cabinet 995 with the auxiliary unit 1010 positioned within the cabinet 995 such that the auxiliary unit 1010 is hidden from view when a front panel or door (not shown) of the cabinet 995 in in place. As shown, the head unit 1005 and the auxiliary unit 1010 are connected via conduits. These conduits may comprise a power and interface cable, one or more steam outlets for the provision of steam (or other cleaning medium) to the head unit 1005 and the return of excess steam to the auxiliary unit 1010. Additionally a waste path may be provided form the head unit 1005 which may be directed via the auxiliary unit 1010 or may be expelled directly to waste. The auxiliary unit 1010 may be provided with a water supply and power supply and may also have a connection to expel (e.g., as an emergency release).

[1106] FIGS. 27 to 29 show an alternative embodiment of the invention. Features with corresponding reference numbers correspond to those discussed previously. It should be appreciated that the features discussed with respect to these figures may be used in combination with the features discussed previously. For example, unless otherwise indicated, the features of the device discussed with respect to FIGS. 1 to 26 correspond to the features of the device shown in FIGS. 27 to 29.

[1107] As shown in FIG. 27A, the receptacle 80 in this embodiment comprises a base portion 80a and lid portion 80b. FIG. 27B shows a perspective view of the device installed in the lid receiving structure 700. FIG. 27C shows a cross-section of the device, taken along the line A-A shown in FIG. 27B.

[1108] As is shown in FIG. 27C, when the lid 550 is in the closed position, the hinge 890 is received inside in the device. As can be seen from both FIGS. 27B and 27C, the device comprises a receptacle lid receiving portion 910 located below the hinge 890. The lid portion 80b of the receptacle is configured to be placed inside the receptacle lid receiving portion 910 as shown in this figure. In this way, the receiving component comprises a first portion for receiving and holding the base portion 80a of the receptacle and a second portion, the receptacle lid receiving portion 910, for receiving and holding the lid portion 80b. The lid portion 80b is held in place in the receptacle lid receiving portion 910 by a retaining feature (not shown). The retaining feature may be a clip or protrusion or another type of retaining feature. The lid portion 80b is shown located in the receptacle lid receiving portion 910 with the bottom or inside of the lid portion 80b facing outwards however the retaining feature may also be able to hold the lid with the bottom of the lid portion facing inwards. The device of the present embodiment comprises three nozzles: a first nozzle 110a, a second nozzle 110b and a third nozzle 110c. Although not shown in FIG. 27C, these are positioned in the locations indicated by the arrows. The pathway of fluid from each of the nozzles is shown in FIG. 27C.

[1109] The first nozzle 110a corresponds to the cleaning element 110 discussed previously. The first nozzle 110a is located in the interior space 82 of the receptacle base portion 80a. The first nozzle 110a is configured to face all of the surface of at least a part of the interior wall 83 of the receptacle 80 on rotation of the receptacle 80 about its central axis by turntable 90 (shown in FIG. 6)thereby allowing the cleaning thereof by the cleaning medium such as steam (not shown) that exits the end of the first nozzle 110a.

[1110] The second nozzle 110b is configured to clean the exterior of the base portion 80a of the receptacle 80. This is done by injecting the cleaning medium such as steam at the side of the base portion 80a. As the receptacle 80 is rotated about its central axis by turntable 90, the entirety of the exterior of the base portion 80a is cleaned.

[1111] The third nozzle 110c is located inside the receptacle lid receiving portion 910. When the lid portion 80b is located in receptacle lid receiving portion 910 as shown in FIG. 27C, the third nozzle may be used to clean the lid portion 80b of the receptacle 80. This is done by injecting the cleaning medium such as steam into the lid portion 80b.

[1112] Each of first, second and third nozzles 110a, 110b and 110c are connected to respective conduits (not shown in this figure). Each conduit may be connected to a valve in the cleaning medium provision apparatus 1010 (not shown in this figure). In this way, the provision of cleaning medium such as steam to each of the nozzles can be controlled. For example, the user may be able to select whether to clean the inside/outside of the base portion 80a of the receptacle and the lid portion 80b. If the user has not put a lid into the device, the user may chose not to activate the third nozzle 110c. Alternatively, a sensor may be located in the receptacle lid receiving portion 910. When the lid portion 80b is detected, the third nozzle may be activated upon activation of the device. When the lid portion 80b is not detected (for example because the receptacle being cleaned does not have a lid or the lid does not require cleaning), the third nozzle 110c may not be activated. Alternatively, a single inlet conduit may be connected to the cleaning medium provision apparatus 1010 which is then split with a divider for feeding into the respective nozzles. When this configuration is used, separate valves may be positioned on each split conduit to control flow to the respective nozzles.

[1113] Although this figure shows three nozzles, only one or two may be used. For example, any combination of the first, second and third nozzles 110a, 110b and 110c may be installed in the device. Specifically the device may comprise the first and third nozzle 110a, 110c but not the second nozzle 110b.

[1114] FIGS. 28A and 28B show the device installed inside a cabinet 995 arranged across a separate head unit 1005 and auxiliary unit 1010. The device arranged across a separate head unit and auxiliary unit as depicted in FIGS. 28A-28B may be mounted flush in or on a surface as described with respect to FIGS. 24A-24F and/or may have a removable/replaceable lid/top surface as described with respect to FIGS. 25A-25B. Further, these features may in some examples be implemented in a device which does not employ rotation of the receptacle. Instead, for example, these features may implemented in a device with a rotating nozzle in which the receptacle is kept stationary and/or in a device with a stationary nozzle and stationary receptacle.

[1115] As discussed with respect to FIGS. 26A-26B, the head unit 1005 includes the components that the user interacts with and the auxiliary unit 1010 contains at least the cleaning medium provision apparatus (e.g., a steam generation apparatus). By arranging the device as a split system in this way, the head unit 1005 can be situated separately from the auxiliary unit 1010 providing flexibility as to the arrangement of the device, especially where space for the device is constrained. As shown, the head unit 1005 may be arranged within the surface 990 of cabinet 995 with the auxiliary unit 1010 positioned within the cabinet 995 such that the auxiliary unit 1010 is hidden from view when a front panel or door 996 of the cabinet 995 in in place. As shown, the head unit 1005 and the auxiliary unit 1010 are connected via conduits 1015. A drain hose 1015a extends from the bottom of the auxiliary unit 1005 and connects to a waste tank (not shown in this figure). Furthermore, a water supply line 1015b carries fluid from a supply tank (not shown in this figure) to the steam generator unit 1010. Further conduits 1015c, 1015d then carry steam from the steam generator unit 1010 to one or more of the first, second and third nozzles 110a, 110b and 110c. In other examples, further conduits not shown in this figure may be used such that each nozzle is fed by a separate conduit. A drain line 1012 extends between the steam generator unit 1010. Further conduits may be included which may comprise a power and interface cable.

[1116] FIG. 29 shows an exploded view of the device installed in the cabinet 995 with the door 996. Also shown in this figure is the waste tank 1020 for receiving the waste from the device and the supply tank 2030 for supplying the cleaning fluid. As can be seen from this figure, the steam generator unit 1010, waste tank 1020 and supply tank 1030 have been removed from the cabinet 995. These may be lifted out of the cabinet 995 or may be slidable on rails. In this way, an operator can easily access the steam generator unit 1010 for maintenance and cleaning and fill or empty the supply and waste tanks respectively.
