Water injection case cover, automatic feeding assembly and clothing treatment device

Abstract

The present invention provides a water injection case cover, an automatic dispensing assembly, and a laundry treatment device. The water injection case cover (3) has a water leakage chamber (39). The water leakage chamber is provided between the water supply channel (11) and the liquid drain chamber (34) of the water injection case cover. The water leakage chamber is provided with a water leakage hole (391) used for draining residual liquid and reducing pressure. By providing the water leakage chamber between the water supply channel and the drain channel (12), water leakage can be completed before the liquid enters the liquid drain chamber, and pressure can be adjusted. This prevents pressure adjustment in the liquid drain chamber, and a more stable liquid drainage effect can be obtained. After detergent is dispensed, residual liquid can be discharged by allowing it to be constantly drained into the dispenser case (4) through the water leakage hole. This prevents residual liquid remaining in the water injection case cover from flowing out of the water injection case cover due to external factors such as vibration of the device or uncertain factors such as fluctuations in internal air pressure, which can affect the user experience.

Description

[Technical field]

[0001] The present invention relates to a washing machine apparatus, and more particularly to a water inlet case cover, an automatic loading assembly and a clothes treatment apparatus. [Background technology]

[0002] 2. Description of the Related Art Clothes treatment devices such as washing machines are essential home appliances.

[0003] Most of the washing machines currently on the market have a structure such as a detergent case or a water supply tank, and water is supplied to a detergent supply case or a washing tub through the structure such as the detergent case or the water supply tank. Most of the detergent cases or water supply tanks have a plate-like structure, and liquid in the detergent case or the water supply tank is introduced through holes in the plate-like structure. For example, the detergent case has a water channel assembly and a water channel cover plate that covers the water channel assembly. The water channel cover plate is provided with a cold water injection hole and a hot water injection hole. The cold water injection hole and the hot water injection hole are provided corresponding to the cold water pipe and the hot water pipe in the water channel assembly, respectively. The cold water injection hole and the hot water injection hole are provided corresponding to the cold water pipe and the hot water pipe in the water channel assembly, respectively, and water is injected into the cold water pipe and the hot water pipe from above the water supply assembly.

[0004] In the prior art, the water channel cover plate is provided with a water leakage hole and a spray hole. The water leakage hole is used to allow water to escape, avoiding uneven discharge and liquid leakage caused by high pressure, and the spray hole allows water to escape into the cleaning space.

[0005] However, when the water leakage outlet and the spray hole are located in the same space, i.e., when water is discharged into the washing space while the water leakage outlet is drained and the pressure is reduced, the pressure becomes unstable, hindering the water discharge effect from the spray hole to the washing space. In addition, the water channel cover plate in the conventional technology can only discharge the liquid inside, and there is a problem that the liquid remains. The residual liquid remaining in the detergent case flows out due to external factors such as the vibration of the device and uncertain factors such as fluctuations in the internal air pressure, which affects the user experience.

[0006] In view of the above, the present invention is proposed. Summary of the Invention [Problem to be solved by the invention]

[0036] In order to make the objectives, technical means and advantages of the embodiments of the present invention clearer, the following will clearly and concisely describe the technical means of the embodiments in combination with the drawings in the embodiments of the present invention. Note that the following embodiments are for explaining the present invention, but are not intended to limit the scope of the present invention.

[0037] In the description of the present invention, unless otherwise clearly defined and limited, the term "connect" should be interpreted in a broad sense as a point to be explained. For example, it may be a fixed connection, a removable connection, or an integral connection. It may also be a mechanical connection or an electrical connection. Furthermore, it may be a direct connection or an indirect connection via an intermediate medium. A person skilled in the art can interpret the specific meaning of the above term in the present invention according to the specific situation.

[0038] The present invention will be described in more detail below in combination with examples.

[0039] As shown in Figures 1 to 12, the present invention provides a clothes treating device, which includes an automatic dosing assembly, which is used to dosing detergent and fabric softener, supplying water, etc., to a washing tub of the clothes treating device.

[0040] The automatic dispensing assembly includes a water tank 1, a water tank cover 2, a water injection case cover 3, a dispenser case 4, and an electric pump 6. Between the water tank 1 and the water tank cover 2, the water injection case cover 3 and the dispenser case 4 are provided in this order from top to bottom. In addition, a fire protection plate 5 is provided on the water tank cover 2.

[0041] Water injection case cover 3 is provided at the opening of water tank 1 as a bottom cover for water tank 1. Protruding ribs 7 are provided on the upper surface of water injection case cover 3. Protruding ribs 7 form different water channel structures and room structures on the upper surface of water injection case cover 3. Both the water channel structures and room structures are areas on the surface of the water injection case cover that are surrounded by protruding ribs 7, and serve as areas for guiding water flow or for introducing water flow or detergent.

[0042] The water channel structure and the area structure guide the water flow and direct the detergent to different positions on the water injection case cover 3, thereby realizing different functions of the water injection case cover 3.

[0043] The water tank cover 2 is provided to press the water injection case cover 3. This positions the water channel structure and area structure between the water tank cover 2 and the water injection case cover 3, thereby preventing leakage of water flow and cleaning liquid.

[0044] The dispenser case 4 is provided in the water tank 1 and is located below the water injection case cover 3. The water injection case cover 3 is provided with a through hole 31 for introducing the water flow and / or cleaning liquid in the water channel structure and area structure to a predetermined position in the dispenser case 4 located below.

[0045] Both the water tank top cover 2 and the water injection case cover 3 are provided with water supply ports, through which water flow and / or cleaning liquid is introduced into the water channel structure and / or room structure of the water injection case cover 3.

[0046] The chamber structure includes a hot water chamber 31, a water supply chamber 32, a mixing chamber 33 and a drainage chamber 34.

[0047] The water channel structure includes a hot water channel 35, a main water channel 36, a labyrinth water channel 37, and a detergent water channel 38. A plurality of drainage chambers 34 may be provided.

[0048] The hot water chamber 31 communicates with a hot water passage 35, and the hot water passage 35 communicates with a mixing chamber 33. In addition, the mixing chamber 33 communicates with a drainage chamber .

[0049] A hot water supply pipe 21 is provided in the water tank top cover 2. The hot water supply pipe 21 communicates with a hot water chamber 31 through the water tank top cover 2. A check valve 22 is provided in the hot water chamber 31. The check valve 22 is connected to a hot water passage 35. When hot water enters the hot water chamber 31 from the hot water supply pipe 21, it passes through the check valve 22 in the hot water chamber 31 and enters the hot water passage 35. The check valve 22 ensures a one-way flow of hot water, that is, from the hot water chamber 31 to the hot water passage 35.

[0050] Since the hot water passage 35 is connected to the mixing chamber 33, the hot water that flows into the hot water passage 35 via the hot water supply pipe 21 can enter the mixing chamber 33 through the hot water passage 35. The hot water then flows into the drainage chamber 34 through the mixing chamber 33, and is discharged from the water injection case cover 3 through the drainage chamber 34.

[0051] A drain hole 321 is provided in the water supply chamber 32. Furthermore, a water supply pipe 23 and a connection structure 25 are provided in the water tank upper cover 2. The water supply pipe 23 is connected to the connection structure 25. Furthermore, the connection structure 25 communicates with the water supply chamber 32, and is connected to a pump via a check valve. The pump is connected to the main water passage 36 and the labyrinth water passage 37, respectively.

[0052] The main water passage 36 communicates with the mixing chamber 33. Also, the labyrinth water passage 37 is provided with a water outlet.

[0053] The liquid that has entered the main water passage 36 from the water supply pipe 23 can enter the mixing chamber 33, and is mixed with the liquid that has entered the mixing chamber 33 from the hot water supply pipe 21, and can enter the drain chamber 34. The liquid that has entered the labyrinth water passage 37 from the water supply pipe 23 can be discharged from the labyrinth water passage 37 through a water outlet provided in the labyrinth water passage 37. In other words, the liquid is discharged from the water injection case cover 3.

[0054] A detergent pipe 24 is connected to the water injection case cover 3. The detergent pipe 24 communicates with a detergent water passage 38, which communicates with the drain chamber 34. The detergent pipe 24 is used to pour in substances such as detergent, fabric softener, etc., transport them through the detergent water passage 38 to the drain chamber 34, and finally discharge them through the drain chamber 34, thereby discharging the detergent, fabric softener, etc. from the water injection case cover 3.

[0055] The drainage chamber 34 is long and U-shaped, and has a plurality of through drainage holes 341 for uniformly discharging the liquid that has entered the drainage chamber 34. The drainage chamber 34 is located above the dispenser case 4. The drainage holes 341 communicate with the dispenser case 4, and allow the liquid in the drainage chamber 34 to flow into the dispenser case 4 by gravity. The liquid in the labyrinth waterway 37 is discharged to the dispenser case 4 through a water outlet provided in the labyrinth waterway 37. Preferably, two drainage chambers 34 are provided. One of them communicates with the mixing chamber 33, and the other drainage chamber 34 communicates with the detergent waterway 38. This allows separate discharge to be realized, and crossing and mixing of the waterways is avoided.

[0056] Pumps are connected to the hot water supply pipe 21, the water supply pipe 23 and the detergent pipe 24, and the liquid is transported to the water injection case cover 3 by the pumps.

[0057] The water injection case cover 3 is further provided with a water leakage chamber 39. The water leakage chamber 39 is provided with a water leakage hole 391. The water leakage chamber 39 communicates with the drainage chamber 34 and the mixing chamber 33. The water leakage hole 391 is used to discharge the liquid in the water leakage chamber 39 from the water injection case cover 3 and into the dispenser case 4.

[0058] The bottom surface of the water leakage chamber 39 is lower than the bottom surfaces of the drainage chamber 34 and the mixing chamber 33. This allows the liquid in the drainage chamber 34 and the mixing chamber 33 to naturally flow into the water leakage chamber 39 and be discharged through the water leakage hole 391. Preferably, the water leakage hole 391 is provided on the edge of the water leakage chamber 39. Furthermore, the bottom surface of the water leakage chamber 39 is inclined. The water leakage hole 391 is located at the lowest position of the inclination so that the liquid in the water leakage chamber 39 can be quickly discharged.

[0059] Water leakage hole 391 communicates with dispenser case 4, and allows the liquid in water leakage chamber 39 to flow into dispenser case 4 by the action of gravity. Water leakage hole 391 makes it possible for the remaining liquid in water filling case cover 3 to drip intermittently into dispenser case 4 after detergent has been dispensed. In other words, by allowing water to be constantly drained into dispenser case 4 through water leakage hole 391, it is possible to prevent the remaining liquid remaining in water filling case cover 3 from leaking out of water filling case cover 3 due to external factors such as device vibration or uncertain factors such as fluctuations in internal air pressure, thereby affecting the user experience.

[0060] A water stop structure 13 is provided in the water leakage chamber 39. The water supply channel 11 and the drainage channel 12 are connected to the water leakage chamber 39. The water leakage chamber 39 communicates with the mixing chamber 33 through the water supply channel 11. The water leakage chamber 39 also communicates with the drainage chamber 34 through the drainage channel 12.

[0061] The connection port between the water supply channel 11 and the water leakage chamber 39 faces the water stop structure 13. The water stop structure 13 is used to reduce the flow rate of the liquid entering the water leakage chamber 39 from the water supply channel 11, thereby slowing down the flow rate of the liquid and discharging it evenly. The water stop structure 13 is a protruding rib provided in the water leakage chamber 39, and has a plate-like structure with a curved surface. Moreover, the curved surface faces the connection port between the water supply channel 11 and the water leakage chamber 39. This makes it possible to form a vortex in the liquid entering the water leakage chamber 39 from the water supply channel 11, and prevents the liquid from passing through the water leakage chamber 39 and being discharged into the drainage channel, thereby reducing the flow rate and improving stability.

[0062] The water leakage hole 391 is provided between the position of the connection port between the water supply channel 11 and the water leakage chamber 39 and the position of the curved surface. Also, the connection port between the water drain channel 12 and the water leakage chamber 39 is located on the opposite side of the curved surface. This makes it possible to slow down the flow rate of the liquid in the water drain channel 12. Preferably, the water supply channel 11 is bent. This makes it possible to further reduce the flow rate of the liquid and make the flow rate slower.

[0063] In the present invention, a leakage chamber is provided between the water supply channel and the drainage channel, allowing water to complete leakage before the liquid enters the drainage chamber, and adjusting the pressure. This avoids the situation where pressure is adjusted in the drainage chamber, making it possible to obtain a more stable drainage effect. After the detergent is completely dispensed, the remaining liquid is discharged by allowing it to be continuously discharged into the dispenser case through the leakage hole. This prevents the remaining liquid remaining in the water injection case cover from leaking out of the water injection case cover due to external factors such as vibration of the device or uncertain factors such as fluctuations in internal air pressure, which can affect the user experience.

[0064] The auto-dosing assembly further includes a temperature detection module and a control module.

[0065] The temperature detection module is used to detect the temperature of the hot water entering water injection case cover 3 from hot water supply pipe 21 and the temperature of the liquid inside water injection case cover 3.

[0066] The control module controls the liquid in the water injection case cover 3 to be discharged at a predetermined temperature based on the detection result of the detection module.

[0067] Preferably, the temperature detection module includes a hot water valve temperature sensor provided in the hot water supply pipe 21 and an automatic charging temperature sensor provided in the water tank top cover 3 .

[0068] The dispenser case 4 is provided in the water tank 1 via a drawer device. By drawing out the dispenser case 4, it becomes possible to manually add detergent, fabric softener, powder detergent, etc. Preferably, the drawer device can have a structure such as a pulley or a guide rail so that the dispenser case 4 can be easily drawn out and pushed back into the water tank 1.

[0069] A hook structure 41 is provided at the front end of the dispenser case 4. The hook structure 41 allows the dispenser case 4 to be detachably connected to the water tank 1. After the connection, a positioning effect is exerted on the dispenser case 4. After the connection, the dispenser case 4 can be pulled outward to release the fixation.

[0070] When the dispenser case 4 is pulled out, the hook structure 41 is released from the water tank 1. At this time, detergent, fabric softener, powder detergent, etc. can be added to the dispenser case 4. After the detergent is added, the dispenser case 4 can be pushed back into the water tank 1. After the dispenser case 4 is pushed back, the hook structure 41 hooks and connects to the water tank 1, locking the dispenser case 4 and providing a stable connection. This is convenient for adding and sucking up detergent.

[0071] Preferably, a plurality of the hook structures 41 are provided at both ends and the center of the front end of the dispenser case 4. In order to further strengthen the stability of the connection of the hook structures 41, the hook structures 41 are provided vertically offset from one another. Specifically, the hook structures 41 are elastic pin structures provided at the front end of the dispenser case 4. The inner wall of the water tank 1 is provided with a slot that fits the elastic pin structure, and the dispenser case 4 is fixed by connecting the elastic pin structure and the slot in cooperation with each other.

[0072] The dispenser case 4 includes a dispenser case cover 42. The dispenser case cover 42 is provided with a detergent inlet 421 and a dispenser case flip cover 422. The dispenser case flip cover 422 is provided at the position of the detergent inlet 421. The detergent inlet 421 can be used to inject detergent into the dispenser case 4. The dispenser case cover 42 is used to prevent dirt from entering the detergent inlet 421.

[0073] The dispenser case cover 42 and the dispenser case flip cover 422 are provided with a locking structure. When the dispenser case flip cover 422 is closed, the dispenser case flip cover 422 is locked to the dispenser case cover 42 by the locking structure. This closes the detergent inlet 421, providing a sealing effect.

[0074] Preferably, the locking structure is a locking plate provided on the dispenser case flip cover 422 and a locking groove provided on the dispenser case cover 42 and cooperates with the locking plate.

[0077] The dispenser case flip cover 422 is provided at the position of the detergent inlet 421 in the dispenser case cover 42 via a rotating structure. This allows the dispenser case flip cover 422 to be opened and closed by rotating.

[0078] The rotation structure includes a rotation shaft hole or a rotation shaft provided in the shield plate 4221. In addition, the dispenser case cover 42 is provided with a rotation shaft or a rotation shaft hole that fits the rotation shaft hole or the rotation shaft. The dispenser case flip cover 422 is connected to the dispenser case cover 42 so as to rotate. In this way, the dispenser case flip cover 422 is opened and closed in a rotational manner. Alternatively, the rotation structure is a rotation shaft positioning structure provided in the dispenser case cover 42 and a rotation shaft provided in the dispenser case flip cover 422. The rotation shaft positioning structure and the rotation shaft are connected to rotate, so that the dispenser case flip cover 422 is opened and closed in a rotational manner.

[0079] A blocking plate 4211 is provided at the edge of the dispenser case flip cover 422. The groove structure of the dispenser case cover 42 is adapted to the blocking plate 4211. When the dispenser case flip cover 422 is closed, the blocking plate 4211 fits into the groove structure of the dispenser case cover 42, thereby achieving a good sealing effect.

[0080] Preferably, a shaft or hole that fits the shaft hole or shaft on the blocking plate 4221 is provided on the side of the groove structure of the dispenser case cover 42 , so that the dispenser case flip cover 422 is provided on the dispenser case cover 42 . EXAMPLES

[0084] Preferably, the dispenser case flip cover 422 is attached to the dispenser case cover 42 by providing a shaft or shaft hole on the bottom surface of the groove structure of the dispenser case cover 42 that matches the shaft hole or shaft on the dispenser case flip cover 422 .

[0085] Preferably, in order to further enhance the sealing effect, the dispenser case flip cover 422 is provided with a sealing ring 4222. After the dispenser case flip cover 422 is closed, the sealing ring 4222 closes the detergent inlet 421 of the dispenser case cover 42, thereby realizing the sealing of the detergent inlet 421.

[0086] Preferably, the sealing ring 4222 has an annular structure, and the sealing ring 4222 fits into the detergent inlet 421 after the dispenser case flip cover 422 is closed.

[0087] The automatic dispensing assembly includes an electric pump 6, and realizes an automatic detergent suction function by supplying a stable negative pressure by the electric pump 6. Considering that the Venturi pump is unstable in discharging liquid, in the present invention, a stable negative pressure is supplied by the electric pump 6 to automatically suck up the detergent.
