[0016] Refer to FIG. 1, in the prior art, the washing tray and washing structure may be used to clean two mop cloths (in some cases, a mop cloth is also referred to as a rag). The tray body 11 of the washing tray includes two sedimentation areas 110 and a sewage outlet 13. These two sedimentation areas 110 each are a V-shaped space. The sedimentation areas 110 are merely illustrative, and the size of the sedimentation areas depend on the size of the washing structure 12 and the mop cloth. Each washing structure 12 includes a plurality of branches 120 (for example, three branches). The plurality of branches 120 converge at the same connection point, and the angles between adjacent branches 120 are equal. For instance, in the figure, there are three branches 120 in each washing structure, and two adjacent branches 120 and the connection point form a 120-degree angle. The sewage outlet 13 is located outside each washing structure 12 (that is, at the edge of the tray body 11, which may also be understood as being located at the rear of the docking station or the washing tray 1 (in a case that a cleaning device is a robotic vacuum cleaner, the direction in which the robotic vacuum cleaner leaves the docking station is considered a front direction). During the washing process, the cleaning member (such as the mop cloth) is cleaned by friction with the washing structure 12 (for example, with the branches 120) and sewage falls and is deposited in the sedimentation area 110. Since the sedimentation area 110 has a slope relative to the sewage outlet 13, some sewage may enter into and be discharged from the sewage outlet 13 along with the water flow. However, other sewage is difficult to enter into and be discharged from the sewage outlet 13 along with the water flow.

[0017] However, in the aforementioned cleaning system, there is instance where some sewage is difficult to be discharged from the waste discharge port along with the water flow, and when this occurs, manual cleaning of the sewage is required, which makes the use of the cleaning system inconvenient.

[0018] The inventor of the present disclosure have analyzed the above technical problem that some sewage is difficult to be discharged from the sewage outlet 13 along with the water flow, and found that the reason for the above problem is that some sewage (as shown as the reference numeral 1201 in FIG. 1) is far from the sewage outlet 13, which is, therefore, difficult to be discharged from the sewage outlet 13 with the water flow. For example, in a case that the cleaning member 201 is a circular mop cloth, the distance that the sewage 1201 has to travel is almost equal to the diameter of the mop cloth, or even greater than the diameter of the mop cloth.

[0019] The present disclosure aims to disclose a washing tray, a docking station, and a cleaning system. The washing tray is designed to allow sewage to more easily be carried by the water flow along the waste discharge channel and into the waste discharge port for discharge, thereby preventing the accumulation of sewage, and the cleaning system is user-friendly.

[0020] Referring to FIGS. 3 to 6, in the first aspect, the present disclosure discloses washing trays 1 according to first and second embodiments of the present disclosure. The washing tray 1 according to the first or second embodiment of the present disclosure includes a tray body 11, and a washing structure 12 and a sewage outlet 13 both arranged on the tray body 11. The washing structure 12 is not limited to the structures shown in FIGS. 3, 4, 5, and 6, as long as the washing structure may rub against the cleaning member (for example, the mop cloth) to achieve the purpose of washing the cleaning member 201 (for example, the mop cloth). In some embodiments of the present disclosure, the washing structure 12 includes a sewage trough 121. In other embodiments, the washing structure 12 also includes a washing rib 122 located between the sewage troughs 121. The way in which the washing rib 122 is located between the sewage troughs 121 is not limited to the spiral arrangement shown in the figures, or a plurality of washing ribs 122 may diverge from the sewage outlet 13. It should be noted here that in embodiments of the present disclosure, the relationship between the washing structure 12 and the tray body 11 includes the following two situations that the washing structure 12 and the tray body 11 may be independent components and then be assembled together; or the washing structure 12 and the tray body 11 are integrally formed. The structure of the sewage trough 121 is not limited to a configuration with a middle recession and high sides shown in the figures (that is, the top of the sewage trough 121 is open, which may also be understood as having no top), as long as the sewage trough 121 may guide the sewage to flow towards the sewage outlet 13.

[0021] Referring to FIGS. 3, 4, 5, and 6, in the washing tray 1 of the first embodiment or the second embodiment of the present disclosure, the sewage outlet 13 is connected to the sewage trough 121 and is surrounded by the washing structure 12 (which may also be understood as the sewage outlet 13 being located inside the washing structure 12), so that during the process of the washing tray 1 being used to wash the cleaning member, the sewage trough 121 and the sewage outlet 13 are both located below the cleaning member 201. In a case that the cleaning member (such as the mop cloth) 201 is taken as a reference in the shape of a circle, the sewage outlet 13 is located within a certain range centered on the center of the cleaning member 201. For example, along a horizontal direction, a distance between the sewage outlet and a center of the cleaning member in a radial direction of the cleaning member is denoted as d, a radius of the cleaning member is D, and 0d/D3/5. When d/D=0, the center of the sewage outlet 13 is directly below the center of the cleaning member 201. The cleaning member 201 mentioned above is circular, and it remains circular after rotation, and taking the cleaning member as a reference, the circle may be called a reference circle. Based on the above principle, in a case that the cleaning member 201 is not circular, a circle formed by the rotation of the cleaning member 201 may be taken as a reference (or a reference circle), and d/D still satisfies the aforementioned relationship, i.e. 0d/D3/5.

[0022] Based on the above arrangement, the process of the washing tray 1 washing the cleaning member 201 is as follows. The cleaning member 201 is installed on the bracket 202 to form a cleaning component 20, and the cleaning component 20 is connected to a drive component through a shaft 221. After the cleaning device (for example, a robotic vacuum cleaner) returns to the docking station and successfully docks with the docking station, the drive component of the robotic vacuum cleaner drives the cleaning member 201 (such as a mop cloth) to rotate, therefore, during the rotation of the cleaning member 201, the cleaning member 201 rubs against the washing structure 12 (as mentioned later, in some embodiments, the cleaning member 201 rubs against the washing rib 122 of the washing structure) to achieve to be washed. Accordingly, the sewage generated (the sewage includes sewage close to the sewage outlet 13 and sewage far from the sewage outlet 13 (for example, sewage near the water inlet 14)) is discharged into the sewage trough 121, flows along the sewage trough 121, and then enters the sewage outlet 13.

[0023] As described above, since the sewage outlet 13 is communicated with the sewage trough 121 of the washing structure 12 and is surrounded by the washing structure 12, so that during the process of the washing tray being used to wash the cleaning member, both the sewage outlet and the washing structure are both located below the cleaning member, and because the sewage outlet 13 is surrounded by the washing structure 12, the sewage outlet 13 is located within the washing area of the washing structure 12, for example, in the middle position (which may be understood as within a certain radius circle centered on the center of the washing structure 12; or, the middle position may also be the center corresponding to the washing structure 12). If the cleaning member 201 is taken as a reference, the position of the sewage outlet 13 may be understood as being located below the cleaning member 201 and within the edge of the cleaning member 201 (for example, in a case that the cleaning member 201 is a circular shape, the sewage outlet 13 correspondingly is located inside the circle). Therefore, compared with the solution that the sewage outlet 13 is located outside the washing structure 12, in the present disclosure, the distance that the sewage has to travel may be greatly shortened and the sewage in the sewage trough 121 is easier to enter and be discharged from the sewage outlet 13 along with the water flow, without the occurrence of sewage deposition. Consequently, there is no longer a need for manual cleaning of the washing tray 1, achieving an automatic cleaning and freeing hands, and realizing a maintenance-free effect, which enhances convenience. In the above process, by supplying water to the sewage trough 121, the sewage generated by the washing structure 12 when washing the cleaning member (for example, mop cloth) may be discharged from the sewage outlet 13 without the need to add an extra power device.

[0024] In some embodiments, a cross-sectional area of the sewage trough 121 gradually decreases along the flow direction of sewage, and the cross-section is perpendicular to the flow direction of sewage. In FIGS. 3, 4, and 5, the flow direction is the spiral direction along the sewage trough, and in FIG. 6, the flow direction may be understood as a radial direction centered the sewage outlet 13.

[0025] As described above, since the cross-sectional area of the sewage trough 121 gradually decreases along the flow direction of sewage, the water impact force is getting greater along the flow direction of sewage, making it easier for sewage to enter the sewage outlet 13 and be discharged.

[0026] Referring to FIGS. 3, 4, and 5, in the washing tray 1 of the first embodiment of the present disclosure, the sewage trough 121 spirals around the sewage outlet 13 with the sewage outlet 13 as an origin. The number of spirals is not limited and may be one, two, etc. In a case that the sewage trough 121 is spiral, the cross-sectional area of the sewage trough 121 may be equal everywhere or not equal (for example, as mentioned above, gradually decrease). It should be noted that in FIGS. 3, 4, and 5, in order to illustrate the spiral shape, the number of spirals is relatively large and the sewage trough 121 is relatively long, however, it is still possible to make the distance that the sewage travels relatively short and the sewage trough 121 is relatively short, for example, the number of spirals may be less than the number of spirals shown in FIGS. 3, 4, and 5. Even if the sewage trough 121 is relatively long, since the washing structure 12 rubs against the cleaning member 201 to wash the cleaning member 201 (for example, in a case that the cleaning member 201 is circular), only part of the sewage is far from the sewage outlet 13, however, since two ends of the sewage trough 121 are communicated with the water inlet 14 and the sewage outlet 13, the sewage far from the sewage outlet 13 may also be more easily impacted by the water from the water inlet 14 and enter the sewage outlet 13.

[0027] As described above, since the sewage trough 121 spirals around the sewage outlet 13, sewage is more likely to enter the sewage outlet 13 along with the water flow and be discharged. For example, since spiraling around the sewage outlet 13 ensures that the distance the sewage travels is short, it makes it easier for the sewage to enter the sewage outlet 13. For another example, the sewage may be subjected to a centrifugal force during the movement of the sewage, making it easier for the sewage to move with the water flow and thus may make it easier for the sewage to enter the sewage outlet 13.

[0028] Referring to FIG. 6, in the washing tray 1 of the second embodiment of the present disclosure, there are a plurality of sewage troughs 121 that converge at the sewage outlet 13.

[0029] As described above, since the plurality of sewage troughs 121 converge at the sewage outlet 13, combined with the sewage outlet 13 being surrounded by the washing structure 12 and taking the cleaning member 201 as a circle for understanding, compared with the sewage outlet 15 being outside the washing structure 12, in the present disclosure, the distance between the sewage and the sewage outlet 13 will not be greater than the diameter of the cleaning member 201, which, therefore, may greatly shorten the distance that the sewage travels, making it easier for the sewage to enter the sewage outlet 13 along with the water flow and be discharged, without the occurrence of sewage deposition. Consequently, there is no longer a need for manual cleaning of the washing tray 1, achieving an automatic cleaning and freeing hands, and realizing a maintenance-free effect, which enhances convenience.

[0030] Referring to FIGS. 3, 4, and 5, in the washing tray 1 of the first embodiment of the present disclosure, the sewage trough 121 spirals from the sewage outlet 13 and forms a shape of an Archimedean spiral. In the case that the sewage trough 121 forms the Archimedean spiral, the cross-sectional area of the sewage trough 121 along the flow direction of sewage may be equal or not equal (as mentioned above, gradually decrease).

[0031] As described above, since the sewage trough 121 spirals around the sewage outlet 13 in shape of an Archimedean spiral, the sewage is more likely to enter the sewage outlet 13 along with the water flow and be discharged. For example, because spiraling around the sewage outlet 13 ensures that the distance the sewage travels is short, it makes it easier for the sewage to enter the sewage outlet 13. For another example, the sewage is subjected to a centrifugal force during the movement of the sewage, which makes it easier for the sewage to move with the water flow and thus may make it easier for the sewage to enter the sewage outlet 13.

[0032] Referring to FIGS. 3, 4, 5, and 6, the washing structure 12 also includes washing ribs 122, which are spaced apart to form the sewage trough 121. The washing ribs spaced apart may be shown in FIGS. 3 to 5, all in a circular shape arranged at intervals; or may be shown in FIG. 6, all in a diverging pattern arranged at intervals in a circumferential direction around the sewage outlet 13. The washing ribs spaced apart are not limited to the above embodiments, as long as the washing ribs 122 may rub against the cleaning member and form the sewage trough 121. The washing ribs 122 are provided with a plurality of protrusions 123 for contact with the cleaning member. In FIG. 6, only one washing rib 122 is shown provided with protrusions 123, and other washing ribs 122 may be also provided with protrusions 123 in the same way (not shown in the figure), which will not be detailed. Based on the role of the protrusion 123 described later, the structure and/or number of the protrusion 123 is not limited. For example, regarding the structure of the protrusion 123, the protrusion 123 may be a protruding point (also called a contact point), or may be a linear structure, etc.

[0033] As described above, by setting the washing ribs 122 at intervals to form the sewage trough 121, and by providing a plurality of protrusions 123 on the washing rib 122, the cleaning member 201 (for example, mop cloth) during rotation rubs against the washing ribs 122 and a plurality of protrusions 123 on the washing ribs 122, and the sewage is directly discharged into the sewage trough 121 and discharged with the water flow. In this way, the cleaning member 201 may be cleaned more thoroughly, improving the cleaning efficiency of washing the cleaning member.

[0034] Referring to FIGS. 3, 4, 5, and 6, in the washing tray 1 according to the first or second embodiment, two washing structures 12 are symmetrically arranged, and each washing structure 12 corresponds to one sewage outlet 13.

[0035] As described above, since the washing structures 12 are symmetrically arranged, during the rotation of the cleaning member (such as mop cloth), it is easier to rub against the two symmetric washing structures 12, thereby improving the cleaning efficiency. Each washing structure corresponds to one sewage outlet 13, so that the washing tray includes a plurality of sewage outlets 13. The plurality of sewage outlets 13 facilitate the rapid collection of sewage and make it easier to discharge sewage.

[0036] Referring to FIGS. 3, 4, and 5, the tray body 11 includes a recessed portion 111, the width of the recessed portion decreases along the recessing direction, and the sewage outlet 13 is located at the lowest position of the recessed portion 111, and the washing structure 12 is located within the recessed portion 111. For example, it may be understood that the recessed portion 111 is in a funnel-shape to achieve the width decreasing along the recessing direction, with the sewage outlet being the bottom of the funnel. In some embodiments, the washing structure 12 and the tray body 11 may be integrally formed to place the washing structure 12 within the recessed portion 111, or the washing structure 12 may be installed (for example, by adhesion or by snap-fit) within the recessed portion 111. The washing tray 1 includes a water inlet 14 that is communicated with the sewage trough 121. In the embodiments of the present disclosure, the water entering the sewage trough 121 from the water inlet 14 has a certain impact force, which may be achieved by the structure of the water supply component (for example, a water pump) or by setting the structure of the water inlet 14. The height of the sewage trough 121 gradually decreases along the flow direction of sewage to ensure that the water inlet 14 is higher than the sewage outlet 13.

[0037] As described above, since the height of the sewage trough 121 gradually decreases along the flow direction of sewage, so that the water inlet 14 is higher than the sewage outlet 13 and water flows downward, allowing sewage to move with the water flow in the sewage trough 121, resulting in faster and cleaner sewage discharge. When the sewage trough 121 spirals around the sewage outlet 13, the combination of the recessed portion 111 and the spiral enables the water and sewage to flow in a vortex shape, making sewage discharge even faster and cleaner.

[0038] In some embodiments, the inner surface of the recessed portion 111 forms a side surface of a truncated-cone cavity.

[0039] As described above, since the inner surface of the recessed portion 111 forms a side surface of the truncated-cone cavity, the structure of the recessed portion 111 is not only simple, but also may be in combination with the gradual decrease in height of the sewage trough 121 along the flow direction of sewage, which ensures that the water inlet 14 is higher than the sewage outlet 13, and the side surface of the truncated-cone cavity combined with the spiral may make the water and sewage flow in a vortex shape, resulting in faster and cleaner sewage discharge.

[0040] Referring to FIG. 2, a second aspect of the present disclosure discloses a docking station 10. The docking station 10 includes any of the aforementioned washing trays 1. The washing tray may be assembled with other components of the docking station in any structure, which will not be detailed. In embodiments of the present disclosure, combining FIGS. 2 and 3, the washing tray 1 is assembled on a base 3. In some cases, the washing tray 1 may also be integrally formed with the base 3, in which case the integral device may also be called the washing tray.

[0041] As described above, the docking station for a cleaning device has the beneficial effects of the washing tray, which will not be detailed.

[0042] Referring to FIG. 2 and combining with FIG. 3, a third aspect of the present disclosure discloses a cleaning system. The cleaning system includes any of the aforementioned docking station 10 and a cleaning device. The cleaning device, for example, is a robotic vacuum cleaner. The cleaning device includes a drive component and a cleaning member 201 as shown in FIG. 7. The cleaning member 201 is driven by the drive component to clean the object to be cleaned. The connection between the cleaning member 201 and the drive component is not limited to the aforementioned connection that the cleaning member 201 is connected to the bracket 202 and the shaft 221 of the bracket 202 is connected to the drive component. When the cleaning device successfully docks with the docking station 10, the cleaning member 201 is located above the washing structure 12 (for example, the mop cloth is located above the washing structure 12, and the mop cloth is circular with the washing structure 12 located directly below the circular area). The drive component drives the cleaning member 201 to rub against the washing structure 12 for a plurality of times, and the cleaning member 201 is washed after the plurality of times of rubbings. When the cleaning device is detached from (i.e. not successfully docked with) the docking station, the cleaning device leaves the docking station, and the drive component drives the cleaning member to clean the floor and other places that need to be cleaned.

[0043] As described above, the drive component drives the cleaning member to rub against the washing structure 12 to clean the cleaning member, the sewage generated by the washing enters into the sewage trough 121 and then is discharged from the sewage outlet 13. In this process, the distance that the sewage travels is short, making it easier for the sewage to enter the sewage outlet 13 along with the water flow and be discharged from the sewage outlet 13, without the occurrence of sewage deposition, and there is no longer a need for manual cleaning of the washing tray 1, achieving an automatic cleaning, a maintenance-free effect and freeing hands, and enhancing convenience.

[0044] Referring to FIG. 5, in some embodiments, the docking station 10 includes a hot air component 4, a water supply component 5, and a valve 6. The valve 6 is communicated with the sewage trough 121, and the communication method between them not limited. For example, the sewage trough 121 is communicated with a water inlet pipe having the water inlet 14, the water inlet pipe is communicated with the valve 6, and two inlets of the valve 6 are connected to the hot air component 4 and the water supply component 5, respectively. In a case that the valve 6 is switched to communicate the sewage trough 121 with the water supply component 5, the water supply component 5 supplies water to the sewage trough 121, allowing the sewage to enter into the sewage outlet 13 along with the water flow. In a case that the valve 6 is switched to communicate the sewage trough 121 with the hot air component 4, the hot air component 4 supplies hot air to the washing structure 12 to dry the cleaning member 201.

[0045] Through the above arrangements, by drying the cleaning member (for example, mop cloth) with hot air, there is no need to take out the cleaning member 201 (for example, mop cloth) to dry by the sunlight, making the cleaning of the cleaning member more automated.

[0046] For the above-mentioned washing tray, docking station, and cleaning system, since the sewage outlet is communicated with the sewage trough of the washing structure and is surrounded by the washing structure, so that in a case that the washing tray is used to clean the cleaning member, the sewage outlet and the washing structure are both located below the cleaning member. Compared with the sewage outlet located outside the washing structure, in the present disclosure, the sewage outlet, being surrounded by the washing structure, is located within the washing area of the washing structure, for example, at the central position of the washing structure (which may be understood as within a certain radius circle centered on the center of the washing structure; of course, the central position may also be the center corresponding to the washing structure). Therefore, the present disclosure may significantly shorten the distance that sewage has to travel, and sewage is more likely to enter the sewage outlet along with the water flow in the sewage trough and be discharged, without the occurrence of sewage deposition.
