Description

Technical Field

[0001] The present invention belongs to the field of clothing processing equipment, and in particular, relates to a water pump device with filtering function and clothing processing equipment. Background Art

[0002] When washing clothes, washing machines easily generate lint. Usually, a filter device for collecting lint is installed on the washing machine. Specifically, the lint filter is a device located at the lower part of the front panel of the washing machine and in front of the drain pump. It is usually installed and used as a component together with the drain pump. It can effectively filter out the longer and larger lint in the discharged washing water. It prevents lint and other foreign matter from being entangled on the impeller during the discharge process of the drain pump, which affects the drainage efficiency and increases the drainage noise.

[0003] However, after the washing machine has been running for a period of time, some lint will accumulate in the lint filter. Since the washer-dryer lacks the necessary lint filter, the accumulation of lint is particularly serious. Users need to manually remove the lint filter and clean it regularly, otherwise it will cause poor drainage. Due to the upper drainage, there is usually 400-600 ml of sewage remaining in the lint filter. In order to prevent it from spilling on the ground, it needs to be released in advance. However, the setting position here is low and there is no suitable container to receive the residual water, so it is more complicated to clean. Therefore, there is an urgent need for a device that does not require regular manual cleaning of the lint filter.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a water pump device and a clothing processing device with a filtering function, in which lint and foreign matter in the water flow will not contact the impeller and the user does not need to manually clean the water pump device regularly.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] In one aspect, a water pump device with filtering function is provided.

[0008] The water pump device with filtering function comprises:

[0009] Pump assembly, including impeller;

[0010] The filter housing comprises a filter chamber and an impeller chamber which are connected to each other, the impeller is arranged in the impeller chamber, and the impeller chamber is connected to a connecting pipe for water outlet;

[0011] A filter diverter hood is arranged in the filter chamber, dividing the filter chamber into an inlet chamber and a drain chamber, wherein the drain chamber is connected to the impeller chamber; a drain port is arranged on the side wall of the water inlet chamber, and a drain pipe is connected to the drain port; the outlet end of the connecting pipe is located in the drain pipe at the drain port.

[0012] In the solution provided by the present invention, when the water flow carrying foreign matter such as wire scraps passes through the filter chamber, the wire scraps are blocked in the water inlet chamber. The water filtered by the filter diverter hood flows normally through the impeller into the connecting pipe, and finally enters the drain pipe through the connecting pipe and is discharged from the water pump device. When the water flows out of the water pump device through the outlet end of the connecting pipe, it will drive the water flow in the water inlet chamber mixed with the wire scraps to flow outward, thereby discharging the separated water mixed with the wire scraps together with the water pump device. This solution can prevent the wire scraps from contacting the impeller, and does not require the user to manually clean the water pump device.

[0013] Furthermore, the filter diverter cover is arranged in the filter cavity at an angle relative to the central axis of the filter cavity.

[0014] Further, the filter diverter cover comprises a filter part and a collection part connected to each other;

[0015] The collecting part is arranged at a position close to the drain outlet, and the filtering part is arranged at a position far away from the drain outlet;

[0016] The filter part is provided with filter holes, while the collection part is not provided with filter holes.

[0017] Furthermore, the filter diverter cover is an arc-shaped plate-like structure protruding toward the drainage cavity.

[0018] Furthermore, a blocking wall is provided in the filter housing, and an opening for water flow from the filter chamber into the impeller chamber is provided in the middle of the blocking wall;

[0019] The end of the collecting part abuts against the connection between the blocking wall and the filter housing; the end of the filtering part abuts against the lower side wall of the filter cavity away from the blocking wall.

[0020] Furthermore, a communication port is provided on the lower side wall of the water inlet cavity, and the communication pipe enters the water inlet cavity through the communication port and is inserted into the drainage pipe through the drainage port.

[0021] Furthermore, two ends of the filter diverter cover are respectively against the drain port and one side of the communication port close to the blocking wall;

[0022] At least part of the connecting pipe abuts against the filter diverter cover and limits the filter diverter cover.

[0023] Furthermore, the outer periphery of the filter diversion cover is tightly fitted with the inner wall of the filter cavity.

[0024] Furthermore, a water outlet connected to the connecting pipe is provided on the side wall of the impeller chamber;

[0025] The side wall where the drain port is located is arranged opposite to the side wall where the water outlet is located.

[0026] On the other hand, a clothes processing device is also provided, and the clothes processing device includes the above-mentioned water pump device with filtering function.

[0027] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0028] 1. In the solution provided by the present invention, when the water flow carrying foreign matter such as wire scraps passes through the filter chamber, the wire scraps are blocked in the water inlet chamber. The water filtered by the filter diverter hood flows normally through the impeller into the connecting pipe, and finally enters the drain pipe through the connecting pipe and is discharged from the water pump device. When the water flows out of the water pump device through the outlet end of the connecting pipe, it will drive the water flow in the water inlet chamber mixed with wire scraps to flow outward, thereby discharging the separated water mixed with wire scraps from the water pump device. This solution can prevent wire scraps from contacting the impeller, and does not require the user to manually clean the water pump device.

[0029] 2. In the solution provided by the present invention, since the filter diverter cover is an arc-shaped plate-like structure protruding toward the water inlet cavity, and no filter holes are provided on the collecting part, the wire scraps filtered through the filter cavity will be washed by the water flow and gathered in the collecting part. As the drainage pipe drains, the wire scraps at the collecting part are also discharged from the filter cavity along with the water flow.

[0030] 3. In the solution provided by the present invention, the connecting pipe can limit the filter diversion cover without the need to set up other additional limiting structures, thus saving costs.

[0031] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] On the other hand, a clothes processing device is also provided, and the clothes processing device includes the above-mentioned water pump device with filtering function.

[0050] The laundry processing device provided by the present invention uses a water pump device with a lint filtering function, so that lint in the washing water will not pass through the impeller and be discharged from the filter chamber through the drain port, and will not entangle the impeller, nor will the lint accumulate in the filter chamber and require manual cleaning by the user. This solution improves the user experience.

[0051] Embodiment 1

[0052] like Figure 1 As shown, this embodiment provides a water pump device with filtering function.

[0053] The water pump device with filtering function comprises:

[0054] The pump assembly 100 includes an impeller 101;

[0055] The filter housing 200 comprises a filter chamber 204 and an impeller chamber 201 which are connected to each other. The impeller 101 is arranged in the impeller chamber 201. The impeller chamber 201 is connected to a connecting pipe 203 for water outlet.

[0056] The filter diverter cover 300 is arranged in the filter chamber 204, dividing the filter chamber 204 into a water inlet chamber and a drainage chamber, and the drainage chamber is connected to the impeller chamber 201; a drainage port 205 is arranged on the side wall of the water inlet chamber, and a drainage pipe 206 is connected to the drainage port 205; the outlet end of the connecting pipe 203 is located in the drainage pipe 206 at the drainage port 205.

[0057] The water pump device with filtering function provided in this embodiment includes: a pump assembly 100, a filter housing 200 and a filter splitter cover 300. The pump assembly 100 includes a motor 102, an impeller shaft, and an impeller 101 arranged on the impeller shaft. The filter housing 200 includes a filter chamber 204 and an impeller chamber 201 that are connected to each other. One end of the impeller shaft is connected to the motor 102, and the other end passes through the side wall of the impeller chamber 201 and enters the impeller chamber 201 to connect with the impeller 101. The impeller chamber 201 has a water outlet 202 on the circumferential side wall of the housing, and a connecting pipe 203 for water outlet is connected to the water outlet 202.

[0058] A filter diverter cover 300 is installed in the filter chamber 204, and the filter diverter cover 300 divides the filter chamber 204 into an inlet chamber and a drain chamber, and the drain chamber is connected to the impeller chamber 201. The water entering the filter chamber 204 first passes through the inlet chamber, and then passes through the filter diverter cover 300 for filtration. The filtered water enters the impeller chamber 201 through the drain chamber, and finally enters the drain pipe 206 through the connecting pipe 203 under the drive of the pump assembly 100 to be discharged from the water pump device. The wire scraps carried in the water flow are blocked in the water inlet chamber by the filter diverter cover 300. When the water flow flows out of the water pump device through the outlet end of the connecting pipe 203, it will drive the water flow in the water inlet chamber mixed with wire scraps to flow outward, thereby discharging the water mixed with wire scraps after separation from the water pump device. This solution can prevent wire scraps from contacting the impeller 101, and there is no need for the user to manually clean the water pump device. In addition, the wire scraps can be discharged from the filter chamber during the drainage process, and there is no need to provide new power for the water flow mixed with wire scraps to discharge from the filter chamber.

[0059] In the solution provided in this embodiment, since the drain port 205 connected to the drain pipe 206 is arranged on the side wall of the filter chamber 204, the outlet end of the connecting pipe 203 connected to the impeller chamber 201 is located in the drain pipe 206. Therefore, the water filtered by the filter diversion cover 300 flows normally through the impeller 101, through the connecting pipe 203, into the drain pipe 206 and finally discharged from the water pump device, and the water flow carrying the filtered foreign matter is also discharged from the filter chamber 204 through the drain pipe 206. This solution can prevent the wire scraps from contacting the impeller 101 and winding around the impeller 101, affecting the drainage efficiency and increasing the drainage noise. In addition, there is no need for the user to manually clean the water pump device. The user experience is improved.

[0060] The solution of this embodiment also includes: the filtering diverter cover 300 is an arc-shaped plate structure protruding toward the drainage cavity.

[0061] The filter splitter cover 300 includes a filter portion 301 and a collection portion 302 connected to each other;

[0062] The collecting part 302 is arranged at a position close to the drain outlet 205, and the filtering part 301 is arranged at a position far away from the drain outlet 205;

[0063] The filter portion 301 is provided with filter holes 303 , while the collection portion 302 is not provided with filter holes.

[0064] In the solution of this embodiment, the filter diverter cover 300 is a plate-like structure, which is convexly arranged to one side, so that its convex surface forms an arc structure. When the filter diverter cover 300 is arranged in the filter cavity 204, the convex side of the filter diverter cover 300 is facing the drainage cavity.

[0065] The filter splitter cover 300 includes two parts, namely a filter part 301 and a collection part 302. The filter part 301 and the collection part 302 are integrally formed structures, the filter part 301 is provided with a filter hole 303, and the collection part 302 is not provided with a filter hole.

[0066] Of course, in other solutions of this embodiment, the filter diverter cover 300 can also be set as an arc-shaped plate-like structure protruding toward the water inlet cavity. Alternatively, the filter diverter cover 300 is only a plate-like structure obliquely arranged in the filter cavity 204, and the area near the drain port 205 is not provided with filter holes, and the rest of the positions are evenly provided with multiple filter holes 303. As long as the purpose of filtering water flow and collecting wire scraps can be achieved.

[0067] In this solution, in order to make it easier for the wire scraps to be discharged from the filter cavity 204 , the collecting portion 302 is disposed close to the side wall where the drain port 205 is located, and the filtering portion 301 is disposed away from the side wall where the drain port 205 is located.

[0068] In a preferred solution of this embodiment, the collecting portion 302 is disposed below the drain port 205 . And along the central axis direction of the filter housing 200 , the lengths of both ends of the drain port 205 are the same as the lengths of both ends of the collecting portion 302 .

[0069] In this solution, a water inlet 208 is provided on the side wall of the water inlet chamber, and a water inlet pipe 209 is connected to the water inlet 208. Specifically, the water inlet 208 is provided on the side wall of the water inlet chamber away from one end of the impeller chamber 201.

[0070] When in use, the water flow carrying the wire scraps enters the filter chamber 204 from the water inlet pipe 209 through the water inlet 208, and the water flow filtered by the filter holes 303 on the filter diverter cover 300 enters the drainage chamber, and then enters the impeller chamber 201, and is discharged to the drainage pipe 206 from the connecting pipe 203 connected to the impeller chamber 201. The wire scraps are blocked in the water inlet chamber by the filter part 301, and then are washed to the position of the collecting part 302 by the water flow entering the water inlet chamber. When the water flow flows out of the water pump device through the outlet end of the connecting pipe 203, it will drive the water flow in the water inlet chamber mixed with the wire scraps to flow outward, so that the water mixed with the wire scraps at the collecting part 302 is discharged from the water pump device.

[0071] The solution of this embodiment also includes: a water outlet 202 connected to the connecting pipe 203 is provided on the side wall of the impeller chamber 201;

[0072] The side wall where the drain port 205 is located is arranged opposite to the side wall where the water outlet 202 is located.

[0073] In the above solution, since the filter housing 200 encloses a receiving chamber, a barrier wall 210 is arranged in the receiving chamber, thereby forming the impeller chamber 201 and the filter chamber 204. That is, the upper side wall and the lower side wall of the filter chamber 204 and the impeller chamber 201 are coaxially arranged.

[0074] Of course, in other schemes of this embodiment, even if the inner diameters of the filter chamber 204 and the impeller chamber 201 are different, the upper side walls and lower side walls of the filter chamber 204 and the impeller chamber 201 are not coaxially arranged, the side wall where the drain port 205 is located and the side wall where the water outlet 202 is located are still relatively arranged.

[0075] Specifically, a water outlet 202 connected to the connecting pipe 203 is provided on the lower side wall of the impeller chamber 201. A drain port 205 is provided on the upper side wall of the filter chamber 204. Thus, one end of the connecting pipe 203 is connected to the water outlet 202, and the other end passes through the filter chamber 204, so that its outlet end is located in the drain pipe 206 at the drain port 205.

[0076] In a more specific solution of this embodiment, the drain port 205 is arranged at a position on the upper side wall of the casing close to the impeller chamber 201 .

[0077] In the preferred solution of this embodiment, the outlet end of the connecting pipe 203 is coaxially arranged with the drain pipe 206. Therefore, the water flow at the outlet end of the connecting pipe 203 enters the drain pipe 206 without energy loss and can flow out of the drain pipe 206 more smoothly.

[0078] The solution of this embodiment also includes: the filter splitter cover 300 is arranged in the filter cavity 204 at an angle relative to the central axis of the filter cavity 204 .

[0079] The filter housing 200 is provided with a barrier wall 210, and an opening is provided in the middle of the barrier wall 210 for water to flow from the filter chamber 204 into the impeller chamber 201;

[0080] The end of the collecting portion 302 abuts against the connection between the blocking wall 210 and the filter housing 200 ; the end of the filtering portion 301 abuts against the lower side wall of the filter cavity 204 away from the blocking wall 210 .

[0081] A communication port 207 is provided on the lower side wall of the water inlet cavity. The communication pipe 203 enters the water inlet cavity through the communication port 207 and is inserted into the drainage pipe 206 through the drainage port 205 .

[0082] In the above solution, the filter splitter cover 300 is obliquely arranged in the filter cavity 204. Specifically, a barrier wall 210 is arranged in the filter housing 200 perpendicular to the central axis of the filter cavity 204, and an opening for water flow to pass through is provided in the middle of the barrier wall 210, so that the impeller cavity 201 and the filter cavity 204 that are interconnected are formed inside the filter housing 200.

[0083] The filter splitter cover 300 is an integrally formed structure and is obliquely disposed in the filter cavity 204. Since the barrier wall 210 is disposed perpendicular to the central axis of the filter cavity 204, the side wall of the filter cavity 204 and the barrier wall 210 are connected to each other and disposed perpendicularly. The end of the collecting portion 302 is firstly abutted against the connection between the barrier wall 210 and the filter housing 200, and then the end of the filter portion 301 is abutted against the lower side wall of the filter cavity 204 away from the barrier wall 210.

[0084] In this solution, a communication port 207 is provided on the lower side wall of the water inlet chamber away from the blocking wall 210 , and the communication pipe 203 enters the water inlet chamber through the communication port 207 and is then inserted into the drainage pipe 206 at the drainage port 205 .

[0085] The solution of this embodiment also includes: two ends of the filtering diverter cover 300 are respectively against the drain port 205 and the communication port 207 on one side close to the blocking wall 210;

[0086] At least a portion of the connecting pipe 203 abuts against the filter diverter cover 300 and limits the position thereof.

[0087] The outer periphery of the filter diversion cover 300 is tightly fitted with the inner wall of the filter cavity 204 .

[0088] In the specific solution of this embodiment, since the drainage port 205 is arranged on the upper side wall of the filter chamber 204 near the barrier wall 210, a communication port 207 is arranged on the lower side wall of the water inlet chamber away from the barrier wall 210. The end of the collecting part 302 on the filter diverter cover 300 is arranged at one end of the drainage port 205 near the barrier wall 210, and the end of the filter part 301 is abutted against the position of the communication port 207 near one end of the barrier wall 210.

[0089] During installation, first install the filter diverter cover 300 in the filter cavity 204, and keep its outer periphery in close contact with the inner wall of the filter cavity 204 so that no wire scraps can pass through the abutment between the two. Then insert the connecting pipe 203 into the water inlet cavity through the connecting hole, and then insert it into the drain pipe 206 at the drain port 205. In this solution, the connecting pipe 203 at the connecting port 207 abuts against the end of the filter part 303 on the filter diverter cover 300, thereby limiting one end of the filter diverter cover 300. The connecting pipe 203 at the drain port 205 also abuts against the end of the collecting part 302 on the filter diverter cover 300, thereby limiting the other end of the filter diverter cover 300. Since the outer periphery of the filter diverter cover 300 is tightly fitted with the inner wall of the filter chamber 204, and both ends of the filter diverter cover 300 are limited by the connecting tube 203, the filter diverter cover 300 can be more firmly fixed in the filter chamber 204 so that it will not swing left and right or up and down under the impact of the water flow.

[0090] In a further solution of this embodiment, the connecting tube 203 passing through the water inlet cavity abuts against the filter diverter cover 300. Thus, the filter diverter cover 300 can be further limited so that it does not rotate in the filter cavity 204. In this solution, if the filter diverter cover 300 is not installed according to the design requirements, the connecting tube 203 cannot be inserted, and the filter diverter cover 300 cannot be limited.

[0091] In the preferred solution of this embodiment, the connecting pipe 203 outside the filter housing 200 has a semicircular structure, and the connecting pipe 203 entering the filter cavity 204 has an arc structure, so that the water flow resistance passing through the connecting pipe 203 is small.

[0092] The water pump device with filtering function provided in this embodiment further includes: an end cover 400 for blocking the end of the filtering cavity 204 .

[0093] The end cap 400 is disposed at one end of the filter chamber 204 away from the barrier wall 210 and is threadedly connected to the filter chamber 204. A knob 401 is disposed on the outer side of the end cap 400. When in use, the end cap 400 is installed or removed by rotating the knob 401.

[0094] When in use, the motor 102 is started, and the water flows into the filter chamber 204 from the water inlet 208, and then turns to pass through the filter diverter cover 300 to enter the drainage chamber. The filtered water is driven by the impeller 101 and discharged from the impeller chamber 201 from the connecting pipe 203. The filtered foreign matter mixed with the washing water is guided to the collection part 302 of the filter diverter cover 300. When the water flows out of the water pump device through the outlet end of the connecting pipe 203, it will drive the water in the water inlet chamber mixed with the wire scraps to flow outward, thereby discharging the water mixed with the wire scraps at the collecting part 302 from the water pump device. This solution can not only prevent the wire scraps from being entangled in the impeller 101, but also prevent the user from manually cleaning the wire scraps. It improves the user experience.

[0095] Embodiment 2

[0096] This embodiment provides a clothes treating device including the water pump device with filtering function described in the above embodiment.

[0097] The clothing processing device described in this embodiment is a washing machine, a washer-dryer or other equipment that needs to collect lint.

[0098] Taking a washing machine as an example, a water pump device with a filtering function is arranged at the lower part of the front panel of the washing machine, which includes a pump assembly 100 and a wire scrap filtering device composed of a filter housing 200 and a filter diverter cover 300. The pump assembly 100 provides power for the overall drainage of the washing machine. In this scheme, the washing water after washing enters the filter chamber 204 through the water inlet pipe 209, flows through the filter diverter cover 300, and the filtered washing water enters the impeller chamber 201, and the wire scraps are washed to the collection part 302 by the water flow. When the water flow in the impeller chamber 201 enters the drain pipe 206 through the diverter pipe, it will drive the water flow in the water inlet chamber mixed with the wire scraps to flow outward, thereby discharging the water mixed with the wire scraps at the collection part 302 from the water pump device, and preventing the wire scraps from being entangled on the impeller 101.

[0099] Since the laundry processing device uses a water pump device with a filtering function, the lint in the washing water will not pass through the impeller and be discharged from the filter chamber through the drain port, so that the lint will not be entangled with the impeller, and the lint will not be accumulated in the filter chamber and need to be cleaned manually by the user. Therefore, users who purchase the laundry processing device do not need to manually clean the lint, which improves the user experience.

[0100] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form.
