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, and a filter device for collecting lint is usually 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 longer and larger lint and hard foreign objects such as coins and buttons in the discharged washing water. It can prevent lint and other foreign objects from being entangled on the impeller during the discharge process of the drain pump, affecting the drainage efficiency and increasing the drainage noise; it can also prevent the drain pump impeller from being stuck or even broken, causing substantial damage to the drain pump.

[0003] However, after the washing machine has been running for a period of time, some lint and foreign matter will accumulate in the lint filter, requiring the user 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. In view of this, the present invention is proposed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a water pump device with a filtering function and a clothing processing device, in which lint and foreign matter carried in the water flow can pass through the water outlet of the filter diverter cover more smoothly into the connecting pipe and be discharged from the water pump device, so that the lint and foreign matter will not contact the impeller, and there is no need for the user to manually clean the water pump device regularly. In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: In one aspect, a water pump device with filtering function is provided.

[0005] The water pump device with filtering function comprises: Pump assembly, including impeller; The filter housing comprises a filter chamber and an impeller chamber which are interconnected, the impeller is arranged in the impeller chamber, and the impeller chamber is connected to a drain pipe; A filter diverter hood is arranged in the filter chamber, and the filter diverter hood extends obliquely toward the side wall of the filter chamber. The extended end has a water outlet for discharging water containing linen chips, and the water outlet is arranged corresponding to the diverter port arranged on the side wall of the filter chamber; the water outlet is connected to a connecting pipe, and an opening is provided on the drain pipe. The connecting pipe is inserted into the drain pipe through the opening, and the inner diameter of the connecting pipe located in the drain pipe is smaller than the inner diameter of the connecting pipe outside the drain pipe.

[0006] The solution provided by the present invention allows the water filtered by the filter diverter cover to flow normally through the impeller and be discharged from the drain pipe, while the water flow carrying the filtered mixed foreign matter enters the drain pipe through the connecting pipe and is discharged from the filter cavity. This solution can prevent the wire scraps from contacting the impeller, and does not require the user to manually clean the water pump device. In addition, because the inner diameter of the connecting pipe in the drain pipe is smaller than the inner diameter of the connecting pipe outside the drain pipe, the negative pressure at the opening of the connecting pipe in the drain pipe is increased, making it easier for the wire scraps to be discharged from the connecting pipe.

[0007] Furthermore, the connecting pipe includes a shunt pipe, a reducer pipe and a pipe-in-pipe connected in sequence; The inner diameter of the diverter pipe is larger than the inner diameter of the pipe-in-pipe, and the inner diameter of the reducer pipe gradually decreases along the water flow direction; The diverter pipe is connected to the water outlet, and the pipe-in-pipe is inserted into the drain pipe through an opening.

[0008] Furthermore, the outlet of the tube-in-tube is located inside the drain pipe and is connected to a funnel-shaped structure; the inner diameter of the funnel-shaped structure gradually increases along the direction of water flow.

[0009] Furthermore, the filter diverter cover comprises a filter part and a diverter part, and the water to be filtered passes through the filter part and the diverter part in sequence for filtration; one end of the diverter part is connected to the filter part, and the other end extends obliquely toward the side wall of the filter chamber; The diversion port is arranged obliquely, and the inclination direction is the same as the inclination direction of the diversion portion; The diverter pipe is extended toward the opening of the drain pipe, and the extension direction of the diverter pipe is inclined to the central axis of the filter cavity.

[0010] Furthermore, a blocking wall is arranged between the filter chamber and the impeller chamber, and a water outlet connecting the filter and the impeller chamber is provided on the blocking wall, and the water outlet is arranged away from the side where the diversion port is located.

[0011] Furthermore, the water pump device also includes an end cap for blocking the end of the filter chamber; A water inlet is provided on the side wall of the filter housing between the end cover and the filter diverter cover, and the water inlet is connected to a water inlet pipe; The inner wall of the water inlet pipe is connected to the inner wall of the filter housing in a tangential manner.

[0012] Furthermore, the water inlet is arranged in the upper area of ​​one side of the filter housing, and a spiral sheet is arranged on the surface of the end cover facing the filter cavity; The spiral sheet first extends obliquely upward toward the water inlet from a side of the side wall of the filter housing opposite to the water inlet, and then bends and extends toward the bottom wall of the filter housing, and the extended end does not exceed the central axis of the filter cavity.

[0013] Furthermore, a foreign matter bucket with an upward opening is provided at the bottom of the filter housing corresponding to the spiral sheet, so as to receive high-density foreign matter entering the filter cavity along with the water flow.

[0014] Furthermore, a filtering structure is provided on the spiral sheet.

[0015] 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.

[0016] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0017] 1. The solution provided by the present invention allows the water filtered by the filter diverter cover to flow normally through the impeller and be discharged from the drain pipe, while the water carrying the filtered mixed foreign matter enters the drain pipe through the connecting pipe and is discharged from the filter cavity. This solution can prevent the wire scraps from contacting the impeller, and does not require the user to manually clean the water pump device. In addition, because the inner diameter of the connecting pipe in the drain pipe is smaller than the inner diameter of the connecting pipe outside the drain pipe, the negative pressure at the opening of the connecting pipe in the drain pipe is increased, making it easier for the wire scraps to be discharged from the connecting pipe.

[0018] 2. In the solution provided by the present invention, since the inner wall of the water inlet pipe and the inner wall of the filter housing are connected in a tangential manner, the water flow entering the filter chamber rotates, so that the wire scraps in the water flow are concentrated in the center of the water flow, and the wire scraps are separated more efficiently.

[0019] 3. The solution provided by the present invention, due to the provision of the spiral blade, the water flow entering the filter chamber forms a vortex water flow after hitting the spiral blade, which is more conducive to the gathering of wire scraps to the center of the vortex water flow and more efficient separation of wire scraps. In addition, due to the provision of the filter part on the spiral blade, the spiral blade only blocks foreign matter such as wire scraps, reducing the resistance to the water flow.

[0027] like Figures 1 to 4 As shown, the present invention provides a water pump device with filtering function and a clothes processing equipment.

[0028] Wherein, the water pump device with filtering function comprises: The pump assembly 100 includes an impeller 101; The filter housing 200 comprises a filter chamber 205 and an impeller chamber 201 which are interconnected. The impeller 101 is disposed in the impeller chamber 201. The impeller chamber 201 is connected to a drain pipe 203. The filter diverter hood 300 is arranged in the filter chamber 205, and the filter diverter hood 300 extends obliquely toward the side wall of the filter chamber 205. The extended end has a water outlet for discharging water containing linen scraps, and the water outlet is arranged corresponding to the diverter port 206 arranged on the side wall of the filter chamber 205; the water outlet is connected to the connecting pipe, and the drain pipe 203 has an opening. The connecting pipe is inserted into the drain pipe 203 through the opening, and the inner diameter of the connecting pipe located in the drain pipe 203 is smaller than the inner diameter of the connecting pipe outside the drain pipe 203.

[0029] The solution provided by the present invention allows the water filtered by the filter diversion cover to flow normally through the impeller and be discharged from the drain pipe, while the water flow carrying the filtered mixed foreign matter enters the drain pipe and is discharged from the filter cavity through the connecting pipe. This solution prevents the water flow from carrying wire scraps into the impeller cavity and contacting the impeller, and does not require the user to manually clean the water pump device.

[0030] 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. Embodiment 1 like Figure 1As shown, this embodiment provides a water pump device with filtering function.

[0031] The water pump device with filtering function comprises: The pump assembly 100 includes an impeller 101; The filter housing 200 comprises a filter chamber 205 and an impeller chamber 201 which are interconnected. The impeller 101 is disposed in the impeller chamber 201. The impeller chamber 201 is connected to a drain pipe 203. The filter diverter hood 300 is arranged in the filter chamber 205, and the filter diverter hood 300 extends obliquely toward the side wall of the filter chamber 205. The extended end has a water outlet for discharging water containing linen scraps, and the water outlet is arranged corresponding to the diverter port 206 arranged on the side wall of the filter chamber 205; the water outlet is connected to the connecting pipe, and the drain pipe 203 has an opening. The connecting pipe is inserted into the drain pipe 203 through the opening, and the inner diameter of the connecting pipe located in the drain pipe 203 is smaller than the inner diameter of the connecting pipe outside the drain pipe 203.

[0032] 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 205 and an impeller chamber 201 that are interconnected. 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 drain port 202 on the circumferential side wall of the housing, and a drain pipe 203 is connected to the drain port 202.

[0033] A filter diverter cover 300 is installed in the filter chamber 205, and the filter diverter cover 300 divides the filter chamber 205 into a water inlet chamber and a water outlet chamber, and the water outlet chamber is connected to the impeller chamber 201. The water entering the filter chamber 205 first passes through the water inlet chamber, and then is filtered by the filter diverter cover 300. The filtered water enters the impeller chamber 201 through the water outlet chamber, and finally is discharged from the impeller chamber 201 through the drain pipe 203 under the drive of the pump assembly 100.

[0034] The side wall of the filter cavity 205 is provided with a diversion port 206. The filter diversion cover 300 extends obliquely toward the side wall of the filter cavity 205, and its extended end has a water outlet for discharging the water flow containing the lint, and the water outlet is arranged corresponding to the diversion port 206. The drain pipe 203 has an opening, and the water outlet is connected to the connecting pipe, and the other end of the connecting pipe is inserted into the drain pipe 203 through the opening.

[0035] In the solution of this embodiment, the inner diameters of the connecting pipes are not the same, and the inner diameter of the connecting pipe located in the drain pipe 203 is smaller than the inner diameter of the connecting pipe outside the drain pipe 203 .

[0036] In the solution of this embodiment, in order to prevent water leakage at the diversion pipe 207 and the drainage pipe 203, a sealing device is provided at the opening of the side wall.

[0037] The solution provided in this embodiment allows the water filtered by the filter diverter cover 300 to flow normally through the impeller 101 and be discharged from the drain pipe 203, while the water flow carrying the filtered mixed foreign matter enters the drain pipe 203 through the connecting pipe and is discharged from the filter chamber 205. This solution can prevent the wire scraps from contacting with 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. In addition, since the inner diameter of the connecting pipe in the drain pipe 203 is smaller than the inner diameter of the connecting pipe outside the drain pipe 203, the water in the drain pipe 203 can pass through the part of the pipe-in-tube 209 located inside the drain pipe 203, and the interference to the water flow is minimal. When the water flow bypasses to form a vortex and continues to flow forward, it will soon flow forward along the annular space between the outer wall of the pipe-in-tube 209 and the inner wall of the drain pipe 203, and the negative pressure generated at the opening of the pipe-in-tube 209 located inside the drain pipe 203 is greater, making it easier for the wire scraps to be discharged from the connecting pipe.

[0038] The solution of this embodiment also includes: the connecting pipe includes a flow dividing pipe 207, a reducing pipe 208 and a pipe-in-pipe 209 connected in sequence; The inner diameter of the diverter pipe 207 is larger than the inner diameter of the pipe-in-pipe 209, and the inner diameter of the reducer pipe 208 gradually decreases along the water flow direction; The diversion pipe 207 is connected to the water outlet, and the pipe-in-pipe 209 is inserted into the drain pipe 203 through the opening.

[0039] The outlet of the tube-in-tube 209 is located inside the drain pipe 203 and is connected to a funnel-shaped structure 210 ; the inner diameter of the funnel-shaped structure 210 gradually increases along the direction of water flow.

[0040] In the solution of this embodiment, the connecting pipe includes three pipes, which are a shunt pipe 207, a reducer pipe 208 and a pipe-in-pipe 209 connected in sequence. The inner diameter of the shunt pipe 207 is larger than the inner diameter of the pipe-in-pipe 209. The reducer section includes a large diameter end and a small diameter end, and the inner diameter of the reducer pipe 208 gradually decreases along the water flow direction.

[0041] One end of the diverter pipe 207 is connected to the outlet of the diversion part, and the other end is connected to the large diameter end of the reducer 208. The small diameter end of the reducer is connected to one end of the pipe-in-pipe 209, and the other end of the pipe-in-pipe 209 is inserted into the drain pipe 203 through the opening.

[0042] In a preferred solution of this embodiment, after the tube-in-tube 209 is inserted into the drain pipe 203 , the extension direction of the tube-in-tube 209 is coaxially extended with the drainage direction of the drain pipe 203 .

[0043] The tube-in-tube 209 has an outlet at the extended end inside the drain pipe 203, and the outlet is connected to a funnel-shaped structure 210. The inner diameter of the funnel-shaped structure 210 gradually increases along the direction of water flow. In other words, the funnel-shaped structure 210 serves as a new outlet for the tube-in-tube 209 inside the drain pipe 203. The purpose of this arrangement is to compress the annular space between the outer wall of the tube-in-tube 209 and the inner wall of the drain pipe 203, so that the water flowing therethrough has a faster flow rate. According to Bernoulli's principle, the faster the speed, the lower the pressure, so that the wire scraps can be better extracted.

[0044] In this solution, the end of the guide portion is inserted into the shunt pipe 207 to connect the two.

[0045] The solution of this embodiment also includes: the filter diverter cover 300 includes a filter part 302 and a diverter part 303, and the water to be filtered passes through the filter part 302 and the diverter part 303 in sequence for filtration; one end of the diverter part 303 is connected to the filter part 302, and the other end extends obliquely toward the side wall of the filter chamber 205; The diversion port 206 is arranged to be inclined, and the inclination direction is the same as the inclination direction of the diversion portion 303; The diverter pipe 207 is extended toward the opening of the drain pipe 203 , and the extension direction of the diverter pipe 207 is inclined to the central axis of the filter chamber 205 .

[0046] The specific structure of the filter diverter cover 300 in this embodiment includes a mounting portion 301, a filter portion 302 and a diverter portion 303 connected in sequence along the water flow direction. The mounting portion 301 is an annular structure and has the same inner diameter along the water flow direction. A mounting groove 211 is provided on the inner peripheral wall of the filter housing 200. The mounting portion 301 has a certain thickness, and part of the mounting portion 301 is inserted into the mounting groove 211 for fixing. In this solution, the filter chamber 205 is divided into two chambers with different inner diameters by using the connection between the mounting portion 301 and the filter portion 302 as the interface.

[0047] One end of the filter part 302 is connected to the mounting part 301, and the other end is connected to the diverter part 303. The filter part 302 is a hollow truncated cone-shaped structure coaxially arranged with the filter cavity 205, and a plurality of filter holes 304 for filtering wire scraps are evenly distributed on its peripheral wall. The inner diameter of the filter part 302 gradually decreases along the direction of water flow, and the diverter part 303 is connected to the position where the inner diameter of the filter part 302 is the smallest. The diverter part 303 is connected to the filter part 302 and extends toward the side wall direction of the filter cavity 205. In other words, there is an angle between the diverter part 303 and the filter part 302. Among them, the filter hole 304 is not arranged on the diverter part 303, and the inner diameter of the diverter part 303 also gradually decreases along the direction of water flow, and a water outlet is arranged at the extended end of the diverter part 303. The maximum inner diameter of the diverter part 303 is smaller than the inner diameter of the filter part 302.

[0048] In the solution of this embodiment, the filter part 302 is designed to be at an angle with the diverter part 303. That is, the diverter part 303 is designed to be at an angle with the axis of the filter cavity 205. In order to facilitate the discharge of the wire scraps from the receiving cavity through the diverter part 303 along with the water flow, the angle between the diverter part 303 and the axis of the filter cavity 205 is set to an obtuse angle.

[0049] In addition, in order to match the corresponding arrangement of the diverter part 303 and the diverter port 206, the diverter port 206 on the filter housing 200 is also arranged at an angle, and the inclination direction is the same as the inclination direction of the diverter part 303. Since the diverter pipe 207 is connected to the water outlet of the diverter part 303, the diverter pipe 207 is also arranged at an angle. Specifically, the diverter pipe 207 is arranged to be inclined to the central axis of the filter chamber 205 and to extend toward the opening of the drain pipe 203. By the inclined arrangement, the wire scraps can be discharged from the filter device more easily and smoothly, reducing the negative pressure loss.

[0050] The solution of this embodiment also includes: in order to facilitate the installation of the filter diversion cover 300, the water outlet on the diversion part 303 can be arranged corresponding to the diversion port 206, and a guide groove corresponding to the filter diversion cover 300 is provided on the inner wall of the filter cavity 205.

[0051] Specifically, the guide groove is a recessed structure provided on the inner surface of the side wall of the filter chamber 205 for limiting cooperation with the filter diverter cover 300, one end of the guide groove is connected to the mounting groove 211, the guide groove extends in the direction of water flow and away from the mounting groove 211, and the other end is connected to the side of the diverter port 206 away from the mounting groove 211. And along the extension direction of the guide groove, the width of the guide groove in the direction perpendicular to the axis of the filter housing 200 gradually decreases.

[0052] The solution of this embodiment also includes: a blocking wall is arranged between the filter chamber 205 and the impeller chamber 201, and a water outlet 204 connecting the filter chamber 205 and the impeller chamber 201 is provided on the blocking wall, and the water outlet 204 is arranged away from the side where the diversion port 206 is located.

[0053] In this solution, when the drainage pump is started, a horizontal water flow will be formed inside the filter housing 200. The closer to the axial center of the filter chamber 205, the greater the flow velocity. The filter housing 200 is subjected to negative pressure. In order to prevent the negative pressure formed by the water flow from offsetting the negative pressure of the wire scraps, the water outlet 204 is set away from the diversion outlet 206 to minimize the impact.

[0054] Specifically, a barrier wall perpendicular to the central axis of the filter chamber 205 is provided between the filter chamber 205 and the impeller chamber 201, and a water inlet 204 is provided on the barrier wall, so that the filter and the impeller chamber 201 are connected. The central vertical line of the water inlet 204 does not coincide with the central axis of the filter chamber 205, and the central vertical line of the water inlet 204 is lower than the central axis of the filter chamber 205. In other words, the water inlet 204 is provided on the side away from the diversion port 206.

[0055] The solution of this embodiment also includes: the water pump device also includes an end cover 400 for blocking the end of the filter cavity 205; A water inlet 212 is provided on the side wall of the filter housing 200 between the end cover 400 and the filter diversion cover 300, and the water inlet 212 is connected to a water inlet pipe 213; The inner wall of the water inlet pipe 213 is tangentially connected to the inner wall of the filter housing 200 .

[0056] In the solution provided in this embodiment, the water pump device also includes an end cover 400, and the end cover 400 blocks the end of the filter cavity 205. A water inlet 212 is provided on the filter housing 200 between the mounting portion 301 of the filter diverter cover 300 and the end cover 400, and the water inlet 212 is connected to a water inlet pipe 213. The interior of the water inlet pipe 213 is tangentially connected to the inner wall of the filter housing 200. In this way, after the water flow enters the filter cavity 205, a rotation effect will be formed, and the rotating water flow can make the wire scraps concentrate in the center of the water flow, so that the wire scraps can be separated more efficiently. In addition, the wire scraps can be rotated with the water flow and will not adhere to the inner wall of the filter part 302, thereby avoiding the wire scraps clogging the filter hole 304 after long-term use, affecting the drainage efficiency and causing drainage failure.

[0057] The solution of this embodiment also includes: the water inlet 212 is arranged in the upper area of ​​one side of the filter housing 200, and the surface of the end cover 400 facing the filter cavity 205 is provided with a spiral sheet 405; The spiral sheet 405 extends obliquely upward from the side of the side wall of the filter housing 200 opposite to the water inlet 212 toward the water inlet 212 , and then bends and extends toward the bottom wall of the filter housing 200 , and its extended end does not exceed the central axis of the filter cavity 205 .

[0058] A foreign matter bucket 406 with an upward opening is provided at the bottom of the filter housing 200 corresponding to the spiral sheet 405 to receive high-density foreign matter entering the filter cavity 205 along with the water flow.

[0059] The spiral sheet 405 is provided with a filtering structure.

[0060] In the scheme of this embodiment, the end cover 400 is connected to the filter chamber 205 by threads. The end cover 400 includes an end cover body 401, a support frame 402 and a top ring 403. A knob 404 for manual rotation is provided on the outer side of the end cover body 401, and a support frame 402 extending into the impeller chamber 201 is provided at the inner outer peripheral edge of the end cover body 401. A top ring 403 is provided at the extended end of the support frame 402, and the extended ends of all support frames 402 are connected to the top ring 403. The top ring 403 is arranged in abutment with one end of the mounting portion 301 away from the filter portion 302. When the end cover 400 is installed in place, all support frames 402 and the top rings 403 connected thereto are arranged close to the side wall of the filter chamber 205.

[0061] In the solution of this embodiment, only one supporting frame 402 is provided, which can avoid affecting the water inlet pipe 213 without affecting the firmness.

[0062] In the solution of this embodiment, a water inlet 212 connected to a water inlet pipe 213 is provided on the filter housing 200 between the mounting portion 301 and the end cover 400. When the end cover 400 is installed in place, the support frame 402 does not face the water inlet 212, thus ensuring that foreign matter in the water flow does not stick to the support frame 402.

[0063] In the present solution, the purpose of providing the top ring 403 is to prevent foolish operation. When the operator or user does not correctly install the filter diverter cover 300, it cannot be normally installed into the filter housing 200 and will inevitably be in a tilted state, which will cause the end cover 400 to be unable to block the filter cavity 205, reminding the installer or user to check.

[0064] The end cap 400 further includes a spiral piece 405. Specifically, the spiral piece 405 is disposed on the inner side of the end cap body 401 and can rotate with the rotation of the end cap 400. That is, when the user removes the end cap 400 from the filter housing 200, the spiral piece 405 is also removed together with the end cap 400.

[0065] When the end cap 400 is installed in place, the spiral piece 405 first extends obliquely toward the water inlet 212 from the side of the side wall of the filter housing 200 opposite to the water inlet 212, and then extends toward the bottom wall of the filter housing 200, and the extended end does not exceed the central axis of the filter cavity 205. The spiral piece 405 forms an opening toward the bottom wall of the filter housing 200.

[0066] In this solution, a filtering structure is provided on the spiral sheet 405. The filtering structure is a through hole provided on the spiral sheet 405, so that the spiral sheet 405 can filter the wire scraps.

[0067] In the preferred solution of this embodiment, the spiral sheet 405 is made of a mesh structure as a whole.

[0068] A foreign body bucket 406 with an upward opening is provided at the bottom of the filter housing 200 corresponding to the spiral sheet 405, and is used to receive foreign bodies with high density that enter the filter chamber 205 along with the water flow. When the water flow carries foreign bodies into the filter chamber 205 through the water inlet 212 from the water inlet pipe 213, if there are heavier foreign bodies with large volume and high density in the water flow, such as keys, coins or game coins, the water flow power is insufficient to drive the foreign bodies into the filter part 302 in the filter diverter cover 300, and the foreign bodies will directly fall into the foreign body bucket 406 after entering through the water inlet 212 along with the water flow.

[0069] In this solution, the foreign matter bucket 406 is also provided on the end cover 400 .

[0070] When the incoming water flow is blocked by the inner wall of the filter housing 200 to form a rotating water flow, it will hit the spiral piece 405, which blocks the water flow and allows it to form a vortex water flow, which is more conducive to the accumulation of wire scraps in the center of the vortex flow. In addition, the spiral piece 405 can block the rotation of foreign objects such as coins, buttons, and zippers, and quickly throw such foreign objects into the foreign object bucket 406 at the bottom of the filter housing 200. Since the spiral piece 405 is a mesh structure, the structure can not only block wire scraps and foreign objects, but also reduce the obstruction to the water flow. In other words, wire scraps and hard foreign objects are separated without sacrificing the power of the water flow.

[0071] When in use, the water flow carries the lint into the filter chamber 205 from the water inlet 212, turns to enter the filter part 302 in the filter diverter cover 300, and the lint is blocked by the filter part 302. The filtered water passes through the filter part 302 and enters the impeller chamber 201, and is driven by the impeller 101 to be discharged from the drain pipe 203. The lint in the filter part 302 is washed into the diverter part 303 by the water flow. When the filtered water flows out of the drain port 202 and enters the drain pipe 203, it encounters the diverter pipe 207, the diameter becomes smaller, the flow rate becomes faster, and when it flows through the opening of the diverter pipe 207 in the drain pipe 203, according to the Bernoulli principle, negative pressure is generated at the opening of the diverter pipe 207, and the water and lint in the diverter pipe 207 are pumped out of the washing machine.

[0072] In the solution provided in this embodiment, the wire scraps can be directly discharged from the storage chamber through the shunt pipe, and the user does not need to manually clean the wire scraps stored in the storage chamber. After the shunt pipe is inserted into the drain pipe, the drainage waterway provides power for the shunt waterway, and no additional power device is required to provide driving force for the waterway corresponding to the shunt pipe, so this solution saves energy.

[0073] Embodiment 2 This embodiment provides a clothes treating device including the water pump device with filtering function described in the above embodiment.

[0074] The clothing processing device described in this embodiment is a washing machine, a washer-dryer or other equipment that needs to collect lint.

[0075] 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 water pump device with a filtering function 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 205 through the water inlet pipe 213, flows through the filter diverter cover 300, and the washing water enters the impeller chamber 201 after filtering, and the wire scraps are washed to the diverter part 303 by the water flow. When the water flow in the impeller chamber 201 flows through the opening of the diverter pipe 207 through the drain pipe 203, negative pressure is generated, and the wire scraps in the guide part connected to the diverter pipe 207 are discharged from the filter chamber 205 to prevent the wire scraps from being entangled on the impeller 101.

[0076] Since the clothing processing device adopts a water pump device with a filtering function, users who purchase the clothing processing device do not need to manually clean the lint, thereby improving the user experience.

[0077] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
