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] After the lint filter collects foreign matter, water will be on the inner surface of the lint filter and cannot be drained through the drain pipe. Since the lint filter is in a semi-enclosed environment, the external consumption is extremely slow. In addition, most of the residual washing water here evaporates and enters the outer drum of the washing machine, causing the washing environment between the inner and outer drums to be extremely bad, which is the source of bacteria breeding and odor. It will cause secondary contamination of clothes when washing.

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

[0046] like Figures 1 to 4 As shown, the present invention provides a water pump device with filtering function and a clothes processing equipment.

[0047] Wherein, the water pump device 4 with filtering function comprises:

[0048] The pump assembly 100 includes an impeller 101;

[0049] The filter housing 200 includes a filter chamber 204 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. A filter device for filtering foreign matter is disposed in the filter chamber.

[0050] A collecting port 208 is provided at the lowest position inside the filter chamber, and the collecting port 208 is connected to a collecting pipe 209 outside the filter chamber 204 to discharge the accumulated water in the filter chamber 204;

[0051] The filter housing 200 and / or the filter device are made of a heat-conducting material, and a heating component 211 is disposed on the outer periphery of the filter housing 200 .

[0052] The solution provided by the present invention is to open a collection port at the lowest position inside the filter chamber, so that the residual water in the impeller chamber and the filter chamber will be collected at the position of the collection port, and then discharged from the filter housing through the collection pipe. The heating component heats the filter housing to dry the inside of the filter housing, thereby preventing the residual water in the device from breeding bacteria and generating odor.

[0053] 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.

[0054] Embodiment 1

[0055] like Figure 1 and Figure 2 As shown, this embodiment provides a water pump device 4 with a filtering function.

[0056] The water pump device 4 with filtering function comprises:

[0057] The pump assembly 100 includes an impeller 101;

[0058] The filter housing 200 comprises a filter chamber 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. A filter device for filtering foreign matter is disposed in the filter chamber.

[0059] A collecting port is provided at the lowest position inside the filter chamber, and the collecting port is connected to a collecting pipe outside the filter chamber to discharge the accumulated water in the filter chamber;

[0060] The filter housing 200 and / or the filter device are made of a heat-conducting material, and a heating component 211 is disposed on the periphery of the filter housing.

[0061] The water pump device 4 with filtering function provided in this embodiment comprises: a pump assembly 100, a filtering housing 200 and a filtering flow divider 300. The pump assembly 100 comprises a motor 102, an impeller shaft, and an impeller 101 arranged on the impeller shaft.

[0062] The filter housing 200 includes a filter chamber 204 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 to enter the impeller chamber 201 and connect to the impeller 101. An opening is provided on the side wall of the housing above the impeller chamber 201, and a drain pipe 203 is connected to the opening. A filter device for filtering foreign matter is provided in the filter chamber 204. When the water flow carrying foreign matter first enters the filter chamber 204, the foreign matter is intercepted by the filter device provided in the filter chamber 204, and the filtered water flow enters the impeller chamber 201, and under the drive of the impeller 101, it enters the drain pipe 203 through the opening and is discharged from the water pump device.

[0063] In use, when the amount of water in the filter housing 200 is insufficient and the pump assembly 100 stops running, the water in the uppermost end of the drain pipe 203 will flow back into the filter housing 200. There is residual water in the filter housing 200, so a collection port 208 is provided on the filter housing 200 at the lowest position inside the filter cavity 204, and the collection port 208 is connected to a collection pipe 209 outside the filter cavity 204. The residual water flows to the position of the collection port 208 in the filter cavity 204, enters the collection pipe 209 through the collection port 208, and is discharged from the filter cavity 204.

[0064] After the residual water in the filter housing 200 is drained, the heating component 211 is heated. When the filter housing 200 is made of a heat-conducting material, the filter housing 200 can absorb the heat generated by the heating component and evaporate the water attached to its inner wall. When the filter housing is not made of a heat-conducting material, the heating component 211 can directly cross the filter housing 200 to directly heat the filter device, allowing the heat generated by the filter device to heat the residual water inside and dry the inner wall of the filter housing 200. This solution can prevent residual water in the device from breeding bacteria and producing odor.

[0065] In this solution, an opening is provided on the side wall of the drain pipe 203 , one end of the collecting pipe 209 is connected to the position of the collecting port 208 , and the other end of the collecting pipe 209 is inserted into the drain pipe 203 through the opening.

[0066] When the filtered water flows out from the drain port 202 and enters the drain pipe 203, it encounters the collecting pipe 209, where the diameter becomes smaller and the flow rate becomes faster. When it flows through the opening of the collecting pipe 209 in the drain pipe 203, according to the Bernoulli principle, negative pressure is generated at the opening of the collecting pipe 209, and the residual water in the collecting pipe 209 is pumped into the drain pipe 203, thereby being discharged from the drainage pump device.

[0067] The solution of this embodiment also includes: a barrier wall is provided between the filter cavity and the impeller cavity 201, and an opening is provided in the middle of the barrier wall;

[0068] A connecting hole 210 connecting the filter chamber and the impeller chamber 201 is also provided at the bottom of the barrier wall.

[0069] The filter chamber has a water inlet 214;

[0070] The filter chamber 204 includes a filter device and a filter screen 405 arranged in sequence along a direction away from the impeller chamber 201, and the filter accuracy of the filter device is lower than the filter accuracy of the filter screen 405; the water inlet 214 is arranged on the filter housing 200 between the filter device and the filter screen 405;

[0071] The collecting port 208 is disposed on a side of the filter screen 405 away from the filtering device;

[0072] The accumulated water in the impeller chamber 201 passes through the filtering device and the filter screen 405 in sequence and is discharged from the collecting port 208 .

[0073] In the above solution, the filter chamber 204 and the impeller chamber 201 are cylindrical structures, a barrier wall is provided between the filter chamber 204 and the impeller chamber 201, and an opening for water flow is provided in the middle of the barrier wall. A connecting hole 210 connecting the filter chamber 204 and the impeller chamber 201 is also provided at the bottom of the barrier wall.

[0074] That is to say, when the amount of water in the filter housing 200 is large, the filtered water flows mainly into the impeller chamber 201 through the opening of the barrier wall, and part of the water flows into the impeller chamber 201 through the connecting hole 210. When the pump assembly 100 stops running, the water in the drain pipe 203 falls back into the impeller chamber 201, and the water in the impeller chamber 201 enters the filter chamber 204 through the connecting hole 210, and then is discharged from the water pump device through the collecting port 208 provided in the filter chamber.

[0075] In a more specific solution, an end cap 400 is provided at one end of the filter chamber 204 away from the impeller chamber 201. The filter chamber 204 includes a coarse filter chamber and a fine filter chamber that are interconnected, and the coarse filter chamber is the area between the filter device and the impeller chamber 201. The fine filter chamber is the area between the filter screen 405 and the end cap 400. The filter holes 304 on the filter device are larger than the filter holes on the filter screen 405. In other words, the filtering accuracy of the coarse filter chamber is smaller than the filtering accuracy of the fine filter chamber.

[0076] A water inlet 214 is provided on the filter housing 200 of the filter chamber 204, and the water inlet 214 is provided between the coarse filter chamber and the fine filter chamber. In other words, the water inlet is provided between the filter device and the filter screen 405. The collecting port 208 is provided in the fine filter chamber.

[0077] When in use, the water flow carrying foreign matter enters the filter chamber from the water inlet 214, and then part of it enters the coarse filter chamber and part of it enters the fine filter chamber. The water flow filtered in the coarse filter chamber is finally discharged into the drain pipe 203 through the impeller chamber 201. The water flow filtered in the fine filter chamber is discharged into the drain pipe 203 through the collection pipe 209. When the pump assembly 100 stops running, the amount of water in the filter housing 200 is small, and the water in the impeller chamber 201 first passes through the coarse filter chamber, and then passes through the filter screen 405 of the fine filter chamber to enter the fine filter chamber, and then flows out of the fine filter chamber from the collection port 208.

[0078] In the solution of this embodiment, the purpose of providing the filter net 405 is to prevent foreign matter from being carried in the water flow entering the collection port 208 , thereby blocking the collection port 208 .

[0079] Since the collecting port 208 is arranged at the lowest point in the filter housing 200 and is arranged in the fine filter chamber, in a scheme of the present embodiment, the inner diameter of the fine filter chamber is set to be larger than the inner diameter of the coarse filter chamber, and the inner diameter of the coarse filter chamber is larger than the inner diameter of the impeller chamber 201, so that the residual water in the drain pipe 203 first enters the impeller chamber 201, and then enters the coarse filter chamber and the fine filter chamber in turn, and is finally discharged through the collecting port 208 in the filter chamber.

[0080] In another solution of this embodiment, the inner diameter of the fine filter chamber is set to be larger than the inner diameter of the coarse filter chamber, and the inner diameter of the coarse filter chamber is equal to the inner diameter of the impeller chamber 201. In this solution, the residual water can still flow into the fine filter chamber and be discharged through the collection port 208.

[0081] like Figure 3 As shown, the scheme of this embodiment also includes: the filtering device is a filtering diverter cover 300, and the filtering diverter cover 300 includes a filtering part 302 and a diverter part 303 which are arranged along the water flow direction and connected at a certain angle;

[0082] The diverter portion 303 has a water outlet, the side wall of the filter chamber 204 has a diverter port 206 corresponding to the water outlet on the diverter portion 303, the diverter port 206 is connected to a diverter pipe 207 located outside the filter chamber 204, the side wall of the drain pipe 203 has an opening, and the diverter pipe 207 is inserted into the drain pipe 203 through the opening.

[0083] The filter device in this embodiment is a filter diverter cover 300. The specific structure of the filter diverter cover 300 includes a mounting portion 301, a filter portion 302 and a diverter portion 303 connected in sequence. The mounting portion 301 is an annular structure and has the same inner diameter along the water flow direction. The mounting portion 301 is fixedly connected to the filter housing 200 of the filter cavity.

[0084] In a solution of this embodiment, a mounting groove is provided on the inner peripheral wall of the filter housing 200 , the mounting portion 301 has a certain thickness, and a part of the mounting portion 301 is inserted into the mounting groove for fixation.

[0085] 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 structure, 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. No filter hole 304 is provided 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 provided 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, and the minimum inner diameter is greater than the diameter of the conventional largest foreign body. In the specific scheme of the present embodiment, the minimum inner diameter of the diverter part 303 is greater than the diameter of a one-yuan coin.

[0086] 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 204. 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 204 is set to be an obtuse angle.

[0087] In a specific solution of this embodiment, in order to facilitate processing, the angle between the diversion portion 303 and the axis of the filter cavity 204 is set to be a right angle.

[0088] In a specific solution of this embodiment, the side wall of the filter cavity 204 has a diversion port 206 corresponding to the water outlet on the diversion portion 303, and the diversion port 206 is connected to a diversion pipe 207 located outside the filter cavity 204;

[0089] The side wall of the drain pipe 203 has an opening, and the diversion pipe 207 is inserted into the drain pipe 203 through the opening.

[0090] In this solution, a diversion port 206 is provided on the side wall of the filter cavity 204, and the water outlet on the diversion portion 303 is provided corresponding to the diversion port 206. In this solution, a protruding structure is provided on the outer side wall of the filter housing 200 at the diversion port 206, and the center of the protruding structure forms the diversion port 206. An opening is provided on the side wall of the drain pipe 203, and one end of the diversion pipe 207 is sleeved on the protruding structure, and the other end passes through the opening provided on the side wall of the diversion pipe 207 and enters the drain pipe 203.

[0091] 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.

[0092] In another solution of this embodiment, a diversion port 206 is provided on the side wall of the filter cavity 204, the end of the diversion part 303 is inserted into the diversion port 206, and the diversion pipe 207 is directly connected to the water outlet on the diversion part 303. In order to prevent water leakage, a sealing device is provided at the position where the diversion part 303 is connected to the diversion port 206.

[0093] As a preferred implementation manner of this embodiment, after the diverter pipe 207 is inserted into the drain pipe 203 , the extension direction of the diverter pipe 207 is coaxially extended with the drain pipe 203 .

[0094] In the solution provided in this embodiment, the wire scraps can be directly discharged from the receiving chamber through the diverter pipe 207, and the user does not need to manually clean the wire scraps stored in the receiving chamber. After the diverter pipe 207 is inserted into the drain pipe 203, the drainage waterway provides power for the diverter waterway, and no additional power device is required to provide driving force for the waterway corresponding to the diverter pipe 207, nor is an additional control system required, which is ingenious and reliable.

[0095] The solution of this embodiment also includes: in order to facilitate and better install the filter diverter cover 300 in place, so that the water outlet on the diverter part 303 can be set corresponding to the diverter port 206, a guide groove corresponding to the filter diverter cover 300 is set on the inner side wall of the filter cavity 204. One end of the guide groove is connected to the installation groove, and the other end of the guide groove extends in a direction away from the installation groove and is connected to a side of the diverter port 206 away from the installation groove. Along the extension direction of the guide groove, the distance between the guide groove and the inner wall of the filter housing 200 on the side where the diverter port 206 is set gradually decreases.

[0096] The solution of this embodiment also includes: the water pump device also includes an end cover 400 that blocks the end of the filter chamber away from the impeller chamber 201;

[0097] The end cover 400 includes a cover body and a plurality of support frames 402 disposed on the end cover body 401 . The support frames 402 extend along the water flow direction and are disposed in close contact with the side walls of the filter cavity.

[0098] The water pump device further comprises a first top ring 403, and the extended ends of the plurality of support frames 402 are all connected to the first top ring 403, and the first top ring 403 is arranged in contact with the end of the filter diverter cover 300;

[0099] A second top ring 404 is further disposed between the first top ring 403 and the end cover 400 . A filter screen 405 is disposed in the middle of the second top ring 404 . A fine filter cavity is formed between the filter screen 405 and the end cover 400 .

[0100] In the solution of this embodiment, the water pump device 4 with filtering function further includes an end cover 400 for blocking the end of the filtering cavity 204 away from the impeller cavity 201 , and the end cover 400 is connected to the filtering cavity 204 by threads.

[0101] The end cover 400 includes an end cover body 401, a plurality of support frames 402, a first top ring 403, and a second top ring 404. A knob 406 for manual rotation is provided on the outer side of the end cover body 401, and a plurality of support frames 402 extending toward the impeller chamber 201 are provided at the periphery of the inner outer edge of the end cover body 401. A first top ring 403 is provided at the extended end of all the support frames 402, and the extended ends of all the support frames 402 are connected to the first top ring 403. The first top ring 403 is provided in contact with one end of the mounting portion 301 away from the filter portion 302. When the end cover 400 is installed in place, all the support frames 402 and the first top ring 403 and the second top ring 404 are provided close to the side wall of the filter chamber 204.

[0102] In this solution, the purpose of setting the first top ring 403 is to prevent foolish operation. When the operator or user does not correctly install the filter diverter cover 300, the filter housing 200 cannot be installed normally and will inevitably be in a tilted state, which will cause the end cover 400 to fail to block the filter cavity 204. Remind the installer or user to check.

[0103] A second top ring 404 is further provided between the first top ring 403 and the end cover 400. A filter screen 405 is provided in the middle of the second top ring 404 perpendicular to the direction of water flow, and a fine filter cavity is formed between the filter screen 405 and the end cover 400. The second top ring 404 and the filter screen 405 can be manufactured by an in-mold injection molding process.

[0104] In the solution of this embodiment, the water inlet 214 is arranged on the filter housing 200 between the mounting portion 301 and the filter screen 405. When the end cover 400 is installed in place, all the support frames 402 are not facing the water inlet 214, so that foreign matter in the water flow will not stick to the support frames 402.

[0105] The solution of this embodiment also includes: the heating component 211 is a heating coil, and the heating coil is wound around the outer periphery of the filter housing 200 along the axial direction of the filter housing.

[0106] In the above solution, the filter housing 200 is made of a heat-conducting material, and a heating coil is wound around its periphery. The filter housing 200 is preferably made of stainless steel, which is corrosion-resistant, has good thermal conductivity, and is easy to process into a thin shell structure. After the heating coil is working, the filter housing 200 can heat up quickly.

[0107] In other solutions of this embodiment, the filter housing 200 may also be made of galvanized steel plate, which is more competitive while achieving the same function.

[0108] In the preferred solution of this embodiment, the filter diverter cover 300 and the filter housing 200 are made of different materials, when one is made of metal, the other is made of non-metallic material. Otherwise, when the heating coil is an electromagnetic induction coil, the metal material cannot generate heat.

[0109] Specifically, in the above solution, the filter housing 200 is made of plastic material, and the filter diverter cover 300 is made of metal material. When the heating coil is working, the filter diverter cover 300 is directly heated through the plastic filter housing 200, and the filter diverter cover 300 generates heat and then heats the residual water inside. Since the filter housing 200 is made of plastic material, it is not easy to dissipate heat, which is more energy-saving.

[0110] It is worth noting that, in the above solution, the metal material can be galvanized steel or stainless steel.

[0111] In a preferred solution of this embodiment, the winding area of ​​the heating coil at least partially overlaps with the projection area of ​​the filter diverter cover 300 toward the filter housing 200. In other words, the heating coil is wound around the outside of the filter housing 200 corresponding to the filter diverter cover 300.

[0112] When in use, the control power module first converts 220V AC into DC, and then converts DC into high-frequency AC to transmit to the heating coil. After the heating coil is energized, a high-frequency alternating magnetic field will be generated at the axis of the heating coil. This magnetic field can also stimulate the components of the water pump device 4 made of metal with filtering function to generate an alternating electric field. The electric field drives the movement of electrons inside the metal to generate high-frequency eddy currents. The eddy currents are affected by the resistance inside the metal and quickly generate heat. In this solution, the installation part 301 of the filter diverter cover 300 and the position of the first top ring 403 are completely surrounded by the heating coil and are completely closed in the circumference, forming a perfect path for the eddy current, so the heating efficiency is the highest.

[0113] In the solution of this embodiment, the filter diverter cover 300 is made of stainless steel. Except for the knob 406, the rest of the structures on the end cover 400 are preferably made of stainless steel.

[0114] In this solution, after the residual water in the filter housing 200 is drained, the heating coil is energized to allow the stainless steel in the cavity to generate heat, heat the internal air, and evaporate the moisture attached to the side wall of the filter housing 200, making the interior of the filter housing 200 dry and preventing bacteria from breeding.

[0115] The solution of this embodiment also includes: a magnet 212 is arranged in the fine filtration cavity, and the surface of the magnet 212 is coated with a heat insulation material.

[0116] In the above scheme, a magnet 212 is arranged in the fine filter cavity, and the magnet 212 is arranged close to the filter screen 405, so that the rope head, button and distinguishing needle following the water flow into the filter cavity 204 can be attracted by the magnet 212.

[0117] In the solution of this embodiment, the magnet 212 is arranged along the radial direction of the fine filter cavity.

[0118] Since the washing machine discharges high-temperature washing water during special programs such as drum cleaning and boiling and washing, in order to prevent the high temperature from demagnetizing the magnet 212, the periphery of the magnet 212 is wrapped with a heat-insulating material.

[0119] The solution of this embodiment also includes: a foreign matter bucket 205 with an upward opening is provided at the bottom of the filter housing 200 corresponding to the first top ring 403 to receive foreign matter entering the filter cavity along with the water flow.

[0120] When the water flow carries foreign matter from the water inlet pipe 214 through the water inlet 213 into the filter chamber 204, if there are heavier foreign matter with larger volume and higher density in the water flow, such as keys, coins or game coins, the water flow power is not enough to drive the foreign matter into the filter part 302 in the filter diversion cover 300, and the foreign matter will directly fall into the foreign matter bucket 205 after entering through the water inlet 213 with the water flow.

[0121] When in use, water flows with wire scraps into the filter chamber from the water inlet 213, most of the water flows into the filter portion 302 in the filter diverter cover 300, and a small amount of water flows into the fine filter chamber through the filter screen 405. As the water flows into the filter chamber 204, light iron-containing foreign objects such as cable heads, buttons, and distinguishing pins can be attracted by the magnet 212. Heavy foreign objects such as keys, coins, or game coins will enter the foreign object bucket 205 and be collected.

[0122] The water flow entering the coarse filter chamber is filtered by the filter section 302, and the lint is blocked by the filter section 302. The filtered water passes through the filter section 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 section 302 is washed into the diverter section 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 tube 207, and the diameter becomes smaller and the flow rate becomes larger. When it flows through the opening of the diverter tube 207 in the drain pipe 203, according to the Bernoulli principle, a negative pressure is generated at the opening of the diverter tube 207, and the water and lint in the diverter tube 207 are pumped out of the washing machine. Similarly, when the drain pipe 203 is draining, the collection tube 209 also generates a negative pressure at the opening in the drain pipe 203, and the water in the fine filter chamber can also be discharged through the collection port 208.

[0123] When the drainage is completed, the pump assembly 100 stops running. At this time, the amount of water in the filter housing 200 is small, and the water in the impeller chamber 201 first passes through the coarse filter chamber, then passes through the filter screen 405 in the fine filter chamber to enter the fine filter chamber, and flows out of the fine filter chamber from the collection port 208. Although the pump assembly 100 stops running, since the other end of the collection pipe 209 is inserted into the drain pipe 203 and extends to the extended end of the drain pipe 203, the collection pipe 209 generates a siphon at this time, and the drainage will not stop until it is completely drained.

[0124] After the water is drained, high-frequency alternating current is applied to the heating coil wound outside the filter housing 200, so that the filter housing 200 and / or the filter diverter cover 300 generate heat to heat the internal air and accelerate the evaporation of the remaining water. The pump assembly 100 is started synchronously to discharge the evaporated water vapor out of the filter housing 200.

[0125] In the solution of this embodiment, in order to determine the time to stop heating, a temperature sensor or a humidity sensor can be set at the drain pipe 203. When the temperature reaches the set temperature condition or the humidity reaches the set humidity condition, it means that the filter shell 200 has been dried and heating can be stopped.

[0126] Of course, in another solution, it is determined based on multiple experiments how long it takes to dry the filter housing 200, and then the heating condition is set to the determined heating time. When it is detected that the heating time reaches the determined heating time, the heating is stopped.

[0127] The solution provided in this embodiment can not only drain the residual water in the filter housing 200, but also make the filter housing 200 dry, thereby preventing bacteria from growing inside and generating odor.

[0128] Embodiment 2

[0129] This embodiment provides a clothes processing device including the water pump device 4 with filtering function described in the above embodiment.

[0130] The clothing processing device described in this embodiment is a washing machine, a washer-dryer or other equipment that needs to collect lint.

[0131] like Figure 4 As shown, taking a washing machine as an example, the washing machine includes a washing machine casing 1, an outer drum 2, an inner drum, a driving device 3 for providing power for the washing machine, and a water pump device 4 with a filtering function.

[0132] The water pump device 4 with 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 through the water inlet pipe 214, 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 diverter part 303 connected to the diverter pipe 207 are discharged from the filter chamber 204 to prevent the wire scraps from being entangled on the impeller 101.

[0133] In addition, an opening is provided above the opening of the drain pipe 203, so that the other end of the collecting pipe 209 can be inserted therein, and the extending length of the collecting pipe 209 in the drain pipe 203 is greater than the extending length of the diverter pipe 207. In the preferred solution of this embodiment, the other end of the collecting pipe 209 extends to the outlet of the drain pipe 203, and is at a certain distance from the outlet, ensuring that it is lower than the collecting port 208.

[0134] The laundry processing device provided in this embodiment uses a water pump device 4 with a filtering function, so users who purchase the laundry processing device do not need to manually clean the lint, thereby improving the user experience. In addition, since the collection pipe 209 and the heating component 211 are provided, the water pump device 4 with a filtering function is kept dry, thereby preventing bacteria from breeding and generating odor.

[0135] Embodiment 3

[0136] This embodiment provides a control method for a clothes treating device using the clothes treating device described in the second embodiment.

[0137] When the laundry processing device is a washing machine. After washing is finished, the washing machine controls the pump assembly 100 to start running and perform the drainage operation. After drainage is finished, the pump assembly 100 stops running. Since the water flow in the drain pipe will fall back into the impeller chamber, there will be water accumulation in the filter housing 200. The accumulated water in the impeller chamber 201 first passes through the coarse filter chamber, and then passes through the filter screen 405 in the fine filter chamber to enter the fine filter chamber, and then flows out of the fine filter chamber from the collection port 208.

[0138] When the accumulated water in the filter housing 200 is drained, the heating component is controlled to start and run for a preset time. That is, high-frequency alternating current is applied to the heating coil wound outside the filter housing 200, so that the filter housing 200 and / or the filter diverter cover 300 generate heat, heat the internal air, and make the water attached to the inner surface of the filter housing 200 evaporate into water vapor. The pump assembly 100 is started synchronously to drive the impeller 101 to rotate and discharge the water vapor out of the washing machine.

[0139] In the control method provided in this embodiment, since the inner surface area of ​​the filter housing is determined, the amount of water attached to the inner surface can also be determined after the accumulated water is drained. Therefore, the interior of the filter housing can be completely dried by running the heating component for a preset time. This solution is simple to operate.

[0140] 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.
