Description

Technical Field

[0001] The utility model belongs to the technical field of clothing processing devices, and in particular relates to a water inlet component of clothing processing equipment, and also relates to clothing processing equipment equipped with the water inlet component. Background Art

[0002] In the prior art, a check valve is usually provided in the water inlet assembly of the clothing processing device. The initial state of the check valve is a closed state. When water enters the clothing processing device, the water flow pushes open the check valve and enters the drum assembly to realize water inlet. After the water inlet is completed, the check valve returns to the closed state.

[0003] The check valve prevents foam and / or water vapor generated during the washing process from flowing back into the water tank through the water inlet pipe of the water inlet assembly, thus preventing the generation of large amounts of foam and / or condensed water in the water tank from affecting the user experience. For example, Chinese utility model patent application number CN201120328717.0 provides a check valve for a washing machine.

[0004] However, when the water inlet valve of the water inlet assembly is closed during use of the above solution, a portion of the water flow cannot open the check valve due to too low water pressure, resulting in a portion of residual water in the water box, making it easy for bacteria to grow in the water box.

[0005] Therefore, designing a water inlet assembly for a clothes processing device that can avoid residual water flow in the water box has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0006] The utility model provides a water inlet assembly for clothing processing equipment.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0033] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0034] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0035] The water inlet assembly of an existing laundry treatment device typically includes a water box 1 and a water inlet pipe 2 connected between the water box 1 and the drum assembly 4. A valve plate 3 is provided at the water outlet 11 of the water box 1 to prevent foam and / or water vapor generated in the drum assembly 4 from flowing back into the water box 1 through the water inlet pipe 2 during the washing process. This would cause a large amount of foam and / or condensation in the water box 1 and affect the user experience. Specifically, when water is flowing into the laundry treatment device, water flows through the water box 1, flushing the valve plate 3 open, and then enters the drum assembly 4 through the water inlet pipe 2. When the laundry treatment device stops flowing, the valve plate 3 returns to a closed state.

[0036] That is, the valve plate 3 needs to be opened by water flow. Therefore, after the water supply to the water box 1 is stopped, a part of the water flow in the water box 1 cannot open the valve plate 3 due to too low water pressure, resulting in the problem that there is always a part of residual water in the water box 1.

[0037] like Figures 1 to 6 As shown, in an embodiment of the present invention, a water inlet assembly of a clothing processing device is introduced to solve the above technical problems.

[0038] The water inlet assembly includes a water box 1 and a water inlet pipe 2 installed between the water box 1 and the cartridge assembly 4. One end of the water inlet pipe 2 is connected to the water outlet 11 of the water box 1, and the other end of the water inlet pipe 2 is connected to the cartridge assembly 4. A valve plate 3 is provided at the water outlet 11 of the water box 1.

[0039] The valve plate 3 is configured to have a closed position for sealing the water outlet 11 of the water box 1, and an open position for opening the water outlet 11 under the action of the incoming water flow when the laundry treatment device is filled with water. An opening 6 is provided at the bottom of the closed portion between the valve plate 3 and the water outlet 11, which is connected to the water outlet 11 and is used to drain residual water in the water box 1.

[0040] Therefore, when the valve disc 3 is in the closed position, the portion of water in the water box 1 that cannot open the valve disc 3 flows out of the water box 1 through the opening 6, thereby preventing residual water from forming in the water box 1. Furthermore, the provision of the opening 6 can also balance the air pressure in the drum assembly 4, thereby preventing the valve disc 3 from being unable to open due to an increase in the air pressure in the drum assembly 4, or from being unable to close due to a decrease in the air pressure in the drum assembly 4. This ensures the operational stability of the valve disc 3 and helps reduce noise generated during operation of the laundry processing apparatus.

[0041] In this embodiment, the opening 6 is provided on the valve plate 3 corresponding to the bottom of the water outlet 11 , and / or the opening 6 is provided at the bottom of the water outlet 11 .

[0042] In this embodiment, the water outlet 11 is provided on the side wall of the water box 1 .

[0043] In some possible embodiments, the valve plate 3 is fitted against the side wall of the water box 1 to close the water outlet 11 , and the opening 6 is provided on the side wall of the water box 1 at the bottom of the water outlet 11 , at least partially extending outside the coverage of the valve plate 3 .

[0044] In other possible embodiments, the water outlet 11 extends to the outside of the water box 1 to form a water guide channel 12, and the valve plate 3 is fitted with the end of the water guide channel 12 away from the inside of the water box 1, that is, fitted with the water outlet end of the water guide channel 12, to close the water outlet 11, and the opening 6 is set at the bottom of the water guide channel 12.

[0045] Specifically, the “opening 6 is provided at the bottom of the water guiding channel 12” means: if the water guiding channel 12 extends obliquely downward from the side wall of the water box 1, then the opening 6 is provided at the bottom of the water outlet end of the water guiding channel 12; if the water guiding channel 12 extends horizontally from the side wall of the water box 1, then the opening 6 is provided at any position at the bottom of the water guiding channel 12; if the water guiding channel 12 extends obliquely upward from the side wall of the water box 1, then the opening 6 is provided at the bottom of the water inlet end of the water guiding channel 12, and / or, is provided on the side wall of the water box 1 at the bottom of the water outlet 11, that is, the opening 6 extends from the bottom of the connection between the water guiding channel 12 and the side wall of the water box 1 along the water guiding channel 12 and / or the side wall of the water box 1.

[0046] In this embodiment, a water outlet connector 15 is further provided on the side wall of the water box 1 for connecting to the water inlet pipe 2. The water outlet connector 15 extends outward from the water box 1. The end of the water outlet connector 15 connected to the side wall of the water box 1 is arranged around the water outlet 11 and the opening 6. The end of the water outlet connector 15 away from the side wall of the water box 1 is used to connect to the water inlet pipe 2. The valve plate 3 is disposed within the area surrounded by the water outlet connector 15 and is used to open or close the water outlet 11.

[0047] When the laundry processing device stops supplying water, the water flow in the water box 1 continues to keep the valve plate 3 open, and the water flows into the water inlet pipe 2. As the water flow in the water box 1 decreases, when the water flow in the water box 1 is insufficient to keep the valve plate 3 open, the valve plate 3 closes, and the remaining water in the water box 1 continues to flow into the water inlet pipe 2 through the opening 6 on the valve plate 3 and / or through the opening 6 on the water box 1, and finally enters the drum assembly 4 until the water in the water box 1 is completely drained.

[0048] Specifically, the opening 6 and the water outlet 11 are both provided on the inner periphery of the water outlet joint 15. When the valve plate 3 is in contact with the side wall of the water box 1, or when the valve plate 3 is in contact with the water outlet end of the water guide channel 12, the water box 1 and the water inlet pipe 2 are connected through the opening 6. The provision of the opening 6 can discharge the residual water in the water box 1 and, to a certain extent, balance the air pressure in the cartridge assembly 4. At the same time, the flow area at the opening 6 is small, and the valve plate 3 can still prevent the foam and / or water vapor generated in the cartridge assembly 4 from flowing into the water box 1 in large quantities. Even if a small amount of foam and / or water vapor enters the water box 1, the foam and / or condensed water can flow back into the cartridge assembly 4 through the opening 6 provided at the bottom of the water outlet 11.

[0049] In some specific embodiments, the valve disc 3 is rotatably disposed on the water box 1. Specifically, the valve disc 3 is connected to the side wall of the water box 1 via an elastic connection portion 33, which is used to drive the valve disc 3 to close the water outlet 11.

[0050] In this embodiment, the elastic connection portion 33 is provided on one side of the valve plate 3 , one end of the elastic connection portion 33 is connected to the valve plate 3 , and the other end is connected to the side wall of the water box 1 around the water outlet 11 .

[0051] When the clothes treating apparatus is not in a state where water is flowing in, that is, when the water inlet valve of the clothes treating apparatus is closed, under the action of the elastic connecting portion 33, the valve disc 3 is in contact with the side wall of the water box 1, or the valve disc 3 is in contact with the water outlet end of the water guiding channel 12. Moreover, there is a certain abutting force between the valve disc 3 and the side wall of the water box 1 or the end face of the water guiding channel 12 away from the inside of the water box 1. This can reduce the displacement of the valve disc 3 relative to the side wall of the water box 1 or the water guiding channel 12 due to vibration during the operation of the clothes treating apparatus, and reduce the collision between the valve disc 3 and the side wall of the water box 1 or the water guiding channel 12 due to vibration.

[0052] Preferably, in this embodiment, the water outlet 11 extends outward from the water box 1 to form a water channel 12. The outlet end of the water channel 12 is configured as an inclined surface, and the distance between the end of the inclined surface near the elastic connection portion 33 and the side wall of the water box 1 is smaller than the distance between the end of the inclined surface away from the elastic connection portion 33 and the side wall of the water box 1. In other words, the distance between the inclined surface and the side wall of the water box 1 gradually increases as it moves away from the elastic connection portion 33. In other words, when the valve plate 3 is in contact with the outlet end of the water channel 12, the valve plate 3 extends obliquely in a direction away from the elastic connection portion 33 and toward the water box 1.

[0053] In some specific embodiments, the elastic connection portion 33 includes a rotating shaft connected between the valve disc 3 and the side wall of the water box 1 , and a spring for driving the valve disc 3 to rotate toward a side close to the water outlet 11 .

[0054] In other specific embodiments, the elastic connecting portion 33 includes a rubber rib 331 connected between the valve plate 3 and the side wall of the water box 1, and the rubber rib 331 is used to connect the valve plate 3 to the side wall of the water box 1 and provide an elastic force for driving the valve plate 3 to rotate toward the water outlet 11.

[0055] Specifically, one end of the rubber rib 331 away from the valve plate 3 is connected to the side wall of the water box 1 between the inner periphery of the water outlet joint 15 and the outer periphery of the water guide channel 12. The rubber rib 331 and the side wall of the water box 1 can be snap-connected, bonded, or screwed.

[0056] Preferably, the rubber rib 331 is snap-fitted to the side wall of the water box 1 .

[0057] Specifically, a mounting hole 14 is provided on the side wall of the water box 1 between the inner periphery of the water outlet connector 15 and the outer periphery of the water channel 12. A rubber rib 331 is connected to the outer edge of the valve plate 3 and has a certain width along the circumference of the valve plate 3. A mounting post 332 is provided on the rubber rib 331, corresponding to the mounting hole 14, and the mounting post 332 is snap-fitted into the mounting hole 14.

[0058] Preferably, Figures 2 to 6 As shown, the mounting post 332 is disposed on the side of the rubber rib 331 facing the side wall of the water box 1, protruding and extending from the side of the rubber rib 331 toward the side wall of the water box 1. In a direction away from the rubber rib 331, the mounting post 332 includes at least a first section 3321 and a second section 3322, which are sequentially arranged. The outer diameter of the first section 3321 is greater than or equal to the inner diameter of the mounting hole 14. The outer diameter of the second section 3322 gradually decreases as it moves away from the rubber rib 331. The outer diameter of the second section 3322 at the end closest to the rubber rib 331 is greater than the outer diameter of the first section 3321, and the outer diameter of the second section 3322 at the end away from the rubber rib 331 is less than the inner diameter of the mounting hole 14.

[0059] Thus, the mounting post 332 is inserted into the mounting hole 14, and the second section 3322 of the mounting post 332 extends to the inner side of the side wall of the water box 1. The end surface of the second section 3322 close to one end of the first section 3321 abuts against the inner side of the side wall of the water box 1, fixing the valve plate 3 on the side wall of the water box 1.

[0060] Preferably, when the second section 3322 abuts against the inner side of the side wall of the water box 1 , the rubber rib 331 at least partially abuts against the outer side of the side wall of the water box 1 , thereby ensuring the stability of the installation of the valve plate 3 .

[0061] Preferably, the end of the second section 3322 away from the first section 3321 is further provided with a third section 3323 extending from the end of the second section 3322 away from the first section 3321 in a direction away from the rubber rib 331, and the outer diameter of the third section 3323 is the same as the outer diameter of the end of the second section 3322 away from the first section 3321.

[0062] Preferably, the first section 3321 , the second section 3322 , and the third section 3323 are coaxially arranged.

[0063] Preferably, the mounting column 332 is configured as a hollow structure.

[0064] Preferably, the inner diameter of the mounting hole 14 gradually decreases in the direction approaching the interior of the water box 1 , and at least the inner diameter of the end of the mounting hole 14 close to the interior of the water box 1 is smaller than the outer diameter of the end of the second section 3322 close to the first section 3321 .

[0065] Preferably, Figure 3 and Figure 4As shown, a guide groove 34 is provided on the side of the rubber rib 331 facing the water outlet 11. The guide groove 34 extends tangentially to the valve disc 3. The provision of the guide groove 34 can reduce the thickness of the rubber rib 331 at the guide groove 34, allowing the rubber rib 331 to bend at the guide groove 34, thereby enabling the valve disc 3 to switch between a closed position and an open position. At the same time, the provision of the guide groove 34 can facilitate the deformation of the rubber rib 331 toward the side wall of the water box 1, thereby increasing the contact force between the valve disc 3 and the water guide channel 12.

[0066] Preferably, in this embodiment, the water box 1 includes a water storage tank and a cover, and a water distribution channel is provided in the cover. The water storage tank includes a peripheral wall and a bottom wall that surround each other to form a groove structure with an open top. A downwardly recessed water outlet groove 16 is provided on the bottom wall of the water storage tank, and the water in the water storage tank flows into the water outlet groove 16 and converges. The water outlet 11 is provided at one end of the water outlet groove 16, and the bottom of the water outlet groove 16 extends downwardly in a direction close to the water outlet 11, and the water outlet 11 corresponds to the bottom of the water outlet groove 16. The water outlet 11 extends toward the outside of the water box 1 along the extension direction of the water outlet groove 16 to form a water guide channel 12, that is, there is a smooth transition between the bottom of the water guide channel 12 and the bottom of the water outlet groove 16, and the water guide channel 12 is inclined downward in a direction away from the interior of the water box 1.

[0067] The water outlet joint 15 is arranged around the water guide channel 12, and the inner periphery of the water outlet joint 15 is spaced from the outer periphery of the water guide channel 12. One end of the water inlet pipe 2 is sleeved on the water outlet joint 15 and has an interference fit with the water outlet joint 15. The other end of the water inlet pipe 2 is connected to the cylinder assembly 4.

[0068] Preferably, the water outlet end of the water guide channel 12 is set as an inclined surface extending downward in a direction away from the water box 1, and the rubber rib 331 is set on the top of the valve plate 3, and the rubber rib 331 is installed on the side wall of the water box 1 between the water guide channel 12 and the water outlet joint 15 through the installation column 332.

[0069] Preferably, the distance between the inner periphery of the water outlet joint 15 and the outer periphery of the water guide channel 12 gradually decreases from top to bottom, thereby facilitating the setting of the mounting hole 14 and improving the guidance of the valve plate 3, thereby avoiding the deviation of the abutment position between the valve plate 3 and the water guide channel 12.

[0070] Preferably, a limiting rib 151 is provided on the inner circumference of the water outlet joint 15. The limiting rib 151 protrudes toward the inner circumference of the water outlet joint 15 and extends along the axial direction of the water outlet joint 15. The two limiting ribs 151 correspond to the left and right sides of the valve plate 3. The side of the limiting rib 151 away from the inner circumferential wall of the water outlet joint 15 is used to guide the valve plate 3, and the auxiliary valve plate 3 is buckled at the water outlet end of the water guide channel 12 under the action of the elastic connecting part 33.

[0071] Preferably, the protruding height of at least one end of the limiting rib 151 away from the side wall of the water box 1 relative to the inner peripheral wall of the water outlet joint 15 gradually decreases in the direction away from the side wall of the water box 1.

[0072] Preferably, the opening 6 is provided at the bottom of the valve disc 3 and is in the shape of a groove that is recessed from the outer edge of the valve disc 3 toward the middle of the valve disc 3. Preferably, the opening 6 is in an inverted V shape.

[0073] In the prior art, valve disc 3 is typically a rubber disc. However, during use, this type of valve disc 3 will deform significantly as the air pressure inside the cartridge assembly 4 changes, resulting in a significant amount of noise. Specifically, when the air pressure inside the cartridge assembly 4 is higher than the external air pressure, the middle of the rubber disc will bulge toward the inside of the water outlet 11, allowing a small amount of air to pass through the sealed area between the edge of the rubber disc and the water outlet 11, generating noise.

[0074] In order to solve the above problem, in this embodiment, the opening 6 provided at the bottom of the closed portion between the valve plate 3 and the water outlet 11 can prevent the valve plate 3 from being deformed by the air pressure in the cylinder assembly 4 to a certain extent.

[0075] Preferably, the valve plate 3 in this embodiment includes a skeleton 31 and an elastic part 32, and the elastic part 32 at least covers the edge of the skeleton 31 on the side close to the water outlet 11; and / or, a partition rib 13 is provided in the water outlet 11 for supporting the middle part of the valve plate 3.

[0076] In some possible embodiments, the valve disc 3 includes a skeleton 31, which is adapted to the shape of the end face of the water-guiding channel 12 away from the interior of the water box 1. The elastic portion 32 is wrapped around the skeleton 31 from the side of the skeleton 31 close to the water outlet 11, and the valve disc 3 abuts against the end face of the water outlet end of the water-guiding channel 12 through the elastic portion 32.

[0077] Preferably, Figure 4 As shown, the central portion of the frame 31 is provided with a protrusion that projects away from the water outlet 11. The elastic portion 32 is a groove-shaped structure that covers the side of the frame 31 near the water outlet 11 and the outer peripheral wall of the frame 31. The groove of the elastic portion 32 contracts inward to fit the outer peripheral wall of the protrusion. The support of the elastic portion 32 by the frame 31 can reduce the deformation of the valve plate 3 caused by changes in air pressure within the drum assembly 4, thereby reducing the operating noise of the clothes processing device.

[0078] In this embodiment, the elastic portion 32 is made of rubber.

[0079] In this embodiment, the rubber rib 331 , the mounting post 332 and the elastic portion 32 are configured as an integral piece.

[0080] Preferably, the frame 31 is provided with a groove that extends from the outer edge of the frame 31 toward the middle. The elastic portion 32 is provided around the outer edge of the frame 31, forming an opening 6 at the groove of the frame 31.
