(13) The garment steaming device 1 comprises a housing 2. For example, the housing 2 has a body 3 and a steam nozzle 4 connected to the body 3. For example, the steam nozzle 4 includes a plurality of vents 5 in an end face 6 of the steam nozzle 4, through which steam is expelled when in use. For example, the body 3 comprises first and second portions 3A, 3B that are attached together and to the steam nozzle 4 to form the housing 2. For example, the steam nozzle 4 comprises an aperture that forms an opening 2A in the housing 2. The steam duct 7 comprises an aperture that forms an opening 7A in the steam duct 7. The openings 2A, 7A in the housing 2 and steam duct 7 are generally circular and are concentrically aligned.
(14) The garment steaming device 1 also comprises a steam channel 8 arranged in the housing 2 for the passage of steam. The channel 8 defines a steam duct 7. The steam duct 7 extends within housing 2 to convey steam through the garment steaming device 1 to the steam nozzle 4. In use, a steam supply hose 9 (shown in
(15) The garment steaming device 1 also comprises a cavity 16 extending into the housing 2. For example, the cavity 16 is defined by an inner collar 13 comprising a cylindrical peripheral wall 13A. The peripheral wall 13A extends from the outer collar 12 in a direction away from the opening 2A in the housing 2. The outer collar 12 thus forms a flange at an end of the inner collar 13. The inner collar 13 protrudes through the opening 7A in the steam duct 7 to extend into the steam channel 8.
(16) The garment steaming device 1 also comprises a fragrance cartridge 10 removeably disposed in the cavity 16.
(17) The garment steaming device 1 also comprises a valve assembly 11 disposed between the cavity 16 and the steam channel 8. For example, the valve assembly 11 comprises outer and inner collars 12, 13, a valve member 14, and a retention member 15.
(18) The valve assembly 11 and the fragrance cartridge 10 are adapted to cooperate such as to allow steam to flow between the steam channel 8 and the cavity 16 when the fragrance cartridge 10 is disposed in the cavity 16. The valve assembly 11 is also adapted to prevent steam from flowing between the steam channel 8 and the cavity 16 when the fragrance cartridge 10 is not disposed in the cavity 16. The outer collar 12 is disposed between the housing 2 and the steam duct 7. The outer collar 12 is generally flat and is annular, having an aperture 12A that is concentrically aligned with the openings 2A, 7A in the housing 2 and steam duct 7.
(19) The inner collar 13 further comprises a lip 13B that extends radially inwardly from the peripheral wall 13A. The lip 13B is disposed towards the end of the inner collar 13 that is distal to the outer collar 12. The lip 13B defines an end of the cavity 16. The aperture 12A in the outer collar 12 is located at the other end of the cavity 16.
(20) The valve member 14 comprises a valve head 17 and a valve plunger 18 that is connected to the valve head 17. The valve head 17 comprises a cylindrical body portion 17A with a flanged base 17B at one end.
(21) The valve plunger 18 comprises a body portion 18A, a base 18B and a plurality of spaced connecting members 18C. The connecting members 18C extend between the body portion 18A and the base 18B to connect the body portion 18A to the base 18B. The connecting members 18C are spaced about the central axis A-A of the cavity 16.
(22) The body portion 18A of the valve plunger 18 is received in a recess in the body portion 17A of the valve head 17 such that the valve plunger 18 and valve head 17 are secured together by an interference fit. Therefore, the valve plunger 18 is fixed relative to the valve head 17. The connecting members 18C extend from the base 18B of the valve plunger and abut the body portion 17A of the valve head 17. Steam is able to flow between the connecting members 18C and through an aperture 18D in the base 18B of the valve plunger 18. Thus, the valve plunger 18 forms a hollow structure that permits the flow of steam therethrough.
(23) The valve member 14 extends in the cavity 16 in the direction of the central axis A-A of the cavity 16 (as shown in
(24) The retention member 15 is in the form of a helical spring 15. The spring 15 extends about the central axis A-A of the cavity 16 to surround the connecting members 18C. The spring 15 is located between the base 18B of the valve plunger 18 and the lip 13B of the inner collar 13. The spring 15 is compressed between the base 18B of the valve plunger 18 and the lip 13B when the base 17B of the valve head 17 is moved away from the inner collar 13 such that the spring 15 biases the base 17B of the valve head 17 against the inner collar 13.
(25) The end of the inner collar 13 that is distal to the outer collar 12 forms an annular valve seat 13C. The base 17B of the valve head 17 is biased against the valve seat 13C by the spring 15 such that the valve member 14 is urged into a closed position (as shown in
(26) The fragrance cartridge 10 comprises a holder 19, a handle 20 and a fragrance receiving element 21. The holder 19 comprises a generally flat base 22 and a peripheral wall 23. The base 22 is shaped to be received in the opening 2A in the housing 2. The peripheral wall 23 extends from the base 22 and defines a recess 24 for receiving the fragrance receiving element 21.
(27) The fragrance receiving element 21 may comprise a porous material. In the present embodiment, the porous material comprises foam. However, it should be recognised that the fragrance receiving element 21 may comprise a different porous material, for example, cork or fabric.
(28) The handle 20 is hingedly attached to the base 22 of the holder 19 such that the handle 20 is moveable relative to the base 22 between an extended position (shown in
(29) The garment steaming device 1 comprises a locking means that is configured to releasably hold the fragrance cartridge 10 in the cavity 16 when the handle 20 in the stowed position. The locking means comprises a first locking protrusion (not shown) and a second locking protrusion 25. The first and second locking protrusions 25 are fixed relative to the housing 2 and extend radially into the opening 2A of the housing 2. The first and second locking protrusions 25 are arranged on opposite sides of the opening 2A in the housing 2.
(30) The locking means further comprises a first locking recess 26 and a second locking recess (not shown). The first and second locking recesses 26 extend into distal ends of the handle 20 of the fragrance cartridge 10 that are each hingedly attached to the base 22 of the holder 19. Thus, the first and second recesses 26 are rotatable about the hinge axis of the attachment between the handle 20 and the base 22 of the holder 19 when the handle 20 is rotated relative to the base 22. The first and second locking recesses 26 are generally U-shaped.
(31) The first and second locking recesses 26 are configured to receive the first and second locking protrusions 25 respectively when the fragrance cartridge 10 is received in the cavity 16. When the handle 20 is in the extended position (as shown in
(32) When the handle 20 is moved to the stowed position (as shown in
(33) To remove the fragrance cartridge 10 from the cavity 16, the handle 20 is moved to the extended position such that the first and second locking recesses 26 are orientated such as to allow movement of the fragrance cartridge 10 relative to the first and second locking protrusions 25.
(34) The garment steaming device 1 comprises a latch 28 that prevents accidental movement of the handle 20 from the stowed position to the extended position. The latch 28 comprises first and second latch elements 28A, 28B that engage when the handle 20 is in the stowed position. The first latch element 28A projects from the handle 20 and the second latch element 28B projects from the base 22 of the holder 19. The user must exert sufficient force on the handle 20 to disengage the first and second latch elements 28A, 28B to move the handle 20 from the stowed position to the extended position. It should be recognised that other configurations of latch 28 are intended to fall within the scope of the invention. For example, in an alternative embodiment (not shown) the second latch element instead comprises a recess that is configured to frictionally receive the first latch element to hold the handle in the stowed position.
(35) In use, the user supplies a few drops of liquid fragrance to the fragrance receiving element 21 with the fragrance cartridge 10 removed from the cavity 16. The porous material of the fragrance receiving element 21 absorbs the drops of liquid fragrance. The fragrance may comprise, for example, an essential oil or perfume.
(36) Once the user has supplied fragrance to the fragrance receiving element 21, the user grips the handle 20, which is initially in the extended position, and manipulates the fragrance cartridge 10 such that the peripheral wall 23 of the holder 19 is inserted into the cavity 16 in the garment steaming device 1. Therefore, the fragrance receiving element 21 is located in the cavity 16. The base 22 of the holder 19 is received in the opening 2A in the housing 2. The base 22 of the holder 19 sits flush to the outer collar 12 which acts as a supporting element that supports the holder 19.
(37) When the fragrance cartridge 10 is inserted into the cavity 16, the peripheral wall 23 of the holder 19 is urged against the base 18B of the valve plunger 18 such that the base 18B is urged towards the lip 13B of the inner collar 13, against the force of the spring 15. This causes the valve head 17, which is connected to the valve plunger 18, to move away from the valve seat 13C such that the valve member 14 moves to an open position (shown in
(38) Steam is able to flow between the steam channel 8 and the cavity 16 when the valve member 14 is in the open position such that fragrance is imparted to the steam from the fragrance receiving element 21. More specifically, steam flows from the steam channel 8 and through a gap between the valve head 17 and the valve seat 13C. The steam then flows through the space between the connecting members 18C of the valve plunger 18 and through the aperture 18D in the base 18B of the valve plunger 18 to enter the cavity 16. The steam in the cavity 16 comes into contact with the fragrance receiving element 21 and then flows back out of the cavity 16, through the valve plunger 18 and the gap between the valve head 17 and the valve seat 13C, and back into the steam channel 8.
(39) The fragrance receiving element 21 is thus fluidly communicated with the steam channel 8 when the fragrance cartridge 10 is received in the cavity 16. Thus, the fragrance absorbed in the fragrance receiving element 21 is released into the steam that flows into the cavity 16. The steam then flows out of the cavity 16 and back into the steam channel 8. The steam is then vented through the plurality of steam vents 5 and onto the garment to be steamed such that the fragrance is imparted onto the garment.
(40) The peripheral wall 23 of the holder 19 comprises a protrusion structure 29. The protrusion structure 29 is in the form of a plurality of protrusions 29A that are distal to the base 22 of the holder 19 such that the protrusions 29A abut the base 18B of the valve plunger 18 when the fragrance cartridge 10 is received in the cavity 16. The protrusions 29A define a plurality of spaces 29B that are located between adjacent protrusions 29A. The spaces 29B are disposed about the periphery of the fragrance receiving element 21 to increase the surface area of the fragrance receiving element 21 that is in contact with the steam in the cavity 16. The spaces 29B also facilitate circulation of steam in the cavity 16. Thus, the protrusion structure 29 increases the rate at which fragrance is imparted to the steam in the cavity 16.
(41) With the fragrance cartridge 10 received in the cavity 16 such that the first and second locking protrusions 25 are received in the first and second locking recesses 26, the user moves the handle 20 to the stowed position. Thus, the locking means holds the fragrance cartridge 10 in place in the cavity 16. Furthermore, the first and second latch elements 28A, 28B engage to prevent the handle 20 from being unintentionally moved back to the extended position, thus reducing the likelihood of accidental removal of the fragrance cartridge 10 from the cavity 16.
(42) The fragrance cartridge 10 is configured to prevent steam from escaping out of the cavity 16 via the opening 2A in the housing 2 when the fragrance cartridge 10 is received in the cavity 16. In the present embodiment, a seal 30 is provided that is configured to seal between the inner collar 13 and the peripheral wall 23 of the holder 19 when the fragrance cartridge 10 is received in the cavity 16. The seal 30 is in the form of an annular sealing gasket 30 that extends radially inwardly from the peripheral wall 13A of the inner collar 13 towards the central axis A-A of the cavity 16. The seal 30 is proximate to the outer collar 12 such that the seal 30 is spaced from the lip 13B of the inner collar 13. Thus, when the fragrance cartridge 10 is received in the cavity 16, the seal 30 abuts the peripheral wall 23 of the holder 19 such that steam is prevented from flowing out of the cavity 16 via the aperture 12A in the outer collar 12 and the opening 2A in the housing 2. In an alternative embodiment (not shown), the seal is instead attached to the peripheral wall of the holder to abut the peripheral wall of the inner collar when the fragrance cartridge is received in the cavity. In yet another embodiment (not shown), the seal is omitted and instead a portion of the peripheral wall of the holder abuts a portion of the peripheral wall of the inner collar when the fragrance cartridge is received in the cavity to form a seal therebetween.
(43) The fragrance cartridge 10 can be removed from the cavity 16 to allow the user to access the fragrance receiving element 21. Therefore, the user can easily replenish the amount of fragrance absorbed in the fragrance receiving element 21. In addition, the fragrance receiving element 21 can be substituted with another fragrance receiving element (now shown) that is used to absorb a different fragrance. Therefore, mixing of different fragrances is prevented and there is no need for all of the fragrance in the fragrance receiving element 21 to be depleted before a different fragrance is used.
(44) To remove the fragrance cartridge 10 from the cavity 16, the user moves the handle 20 from the stowed position to the extended position, by exerting sufficient force on the handle 20 to disengage the first and second latch elements 28A, 28B. Once the handle 20 is in the extended position, the first and second locking recesses 26 are orientated such that the first and second locking protrusions 25 can be removed therefrom and so the fragrance cartridge 10 can easily be removed from the cavity 16. When the fragrance cartridge 10 is removed from the cavity 16, the valve member 14 is urged back to the closed position (shown in
(45) In the above described embodiment, the peripheral wall 23 of the holder 19 comprises a protrusion structure 29 that is configured to increase the surface area of the fragrance receiving element 21 that is in contact with the steam in the cavity 16. This increases the rate at which fragrance is imparted to the steam in the cavity 16. However, it should be recognised that the protrusion structure 29 may be omitted. In one alternative embodiment (shown in
(46) In the above described embodiment, the valve plunger 18 comprises a hollow structure that allows for steam to flow between the steam channel 8 and the cavity 16 when the valve member 14 is in the open position (as shown in
(47) Although in the above described embodiments the outer and inner collars 12, 13 are separate components, in an alternative embodiment (not shown) the outer and inner collars are integrally formed. In one embodiment, the outer and/or inner collar is integrally formed with the housing of the garment steaming device.
(48) Although in the above described embodiments the body 3 comprises first and second portions 3A, 3B that are attached together and to the steam nozzle 4 to form the housing 2, in alternative embodiments (not shown), the first and second portions of the body and/or the steam nozzle are integrally formed.
(49) Although in the above described embodiments the opening 2A in the housing 2 is an aperture in the steam nozzle 4, in an alternative embodiment (not shown) the opening in the housing is an aperture in the body.
(50) In the above described embodiments the cavity 16 extends into the steam nozzle 4 of the housing 2 such that the fragrance cartridge 10 is received in the housing 2 to impart fragrance to the steam. However, in alternative embodiments (not shown), the cavity 16 instead extends into the body 3 such that the fragrance cartridge 10 is received in the body 3 to impart fragrance to the steam. Alternatively, a portion of the steam hose may comprise a housing with a steam channel that extends therethrough. The housing has a cavity and the fragrance cartridge is received in the cavity to impart fragrance to the steam flowing through the steam hose. In yet another embodiment (not shown), the steaming device comprises a base unit that houses the steam generator, and the steam hose fluidly communicates the base unit with the steam channel in the garment steaming device. The cavity extends into the base unit such that the fragrance is imparted to the steam in the steam generator.
(51) Although in the above described embodiment the retention member 15 comprises a helical spring, in alternative embodiments (not shown) the garment steaming device comprises a different type of retention member. For example, the retention member may instead comprise a different type of spring or a portion of resilient material that is compressed between the lip of the inner collar and the base of the valve plunger to bias the valve member into the closed position. In one alternative embodiment (not shown), the retaining member is disposed between the lip of the inner collar and the base of the valve head such that the retaining member is under tension when the valve member is moved to the open position.
(52) Although in the above described embodiment the garment steaming device 1 is a steamer head 1, it shall be recognised that other types of garment steaming device are intended to fall within the scope of the invention. For instance, in an alternative embodiment (not shown), the garment steaming device is a steam iron.
(53) The above embodiments as described are only illustrative, and not intended to limit the technique approaches of the present invention. Although the present invention is described in details referring to the preferable embodiments, those skilled in the art will understand that the technique approaches of the present invention can be modified or equally displaced without departing from the spirit and scope of the technique approaches of the present invention, which will also fall into the protective scope of the claims of the present invention. In the claims, the word comprising does not exclude other elements or steps, and the indefinite article a or an does not exclude a plurality. Any reference signs in the claims should not be construed as limiting the scope.
