DETAILED DESCRIPTION

[0035] As described in the background art, the lint filter on the clothing processing device in the related art will accumulate some lint after being used for a period of time, so the user needs to clean the lint filter regularly. The process of cleaning the lint filter is relatively complicated, which causes inconvenience to the user.

[0036] In view of this, the embodiment of the present application aims to provide a lint filter assembly and a clothing processing device, by setting a blade on the side wall of the filter element, setting a convex rib on the inner wall of the cavity; and the output shaft of the drain pump is penetrated through the housing. When the speed of the drain pump is greater than the preset value, the water flow through the filter element increases, so that the filter element overcomes the adsorption force between the first magnetic part and the second magnetic part and moves toward the side of the drain pump. At this time, the blade fits with the convex rib, and the filter element rotates with the drain pump. When the filter element rotates, it can drive the lint in the washing water to move toward the inner wall of the cavity, and the blade and the convex rib can grind the longer lint in the washing water. The chopped lint can be discharged with the washing water without accumulating in the lint filter, so that the user does not need to clean the lint filter regularly, which is conducive to improving the user experience. In normal use, the speed of the drain pump can be made less than the preset value. At this time, the filter element moves away from the drain pump under the action of the adsorption force between the first magnetic part and the second magnetic part, so that the blade is separated from the convex rib, the filter element is separated from the output shaft, and the lint filter can filter the washing water normally.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Figure 1 is a front view of a lint filter assembly provided by an embodiment of the present application in a first state; Figure 2 yes Figure 1 Middle AA section view; Figure 31 is a front view of a lint filter assembly provided by an embodiment of the present application in a second state. In this embodiment, the first direction X is parallel to the axial direction of the filter element.

[0039] Please refer to Figure 1-Figure 3 The present embodiment provides a lint filter assembly 10, which can be arranged on the drainage pipe of the clothing processing equipment. Specifically, the lint filter assembly 10 includes a drainage pump 100 and a lint filter 200, wherein the lint filter 200 includes a housing 210 and a filter element 220, the filter element 220 is located in the cavity, the drainage pump 100 can drive the washing water in the drainage pipe to enter the housing 210, and the washing water is filtered by the filter element 220 and then discharged from the housing 210, thereby removing the larger lint mixed in the washing water. The output shaft 110 of the drainage pump 100 is passed through the housing 210 so as to be connected with the filter element 220.

[0040] A plurality of blades 224 are provided on the side wall 223 of the filter element 220, and the blades 224 can be detachably connected to the side wall 223 by fasteners such as bolts. A plurality of ribs 203 are provided in the housing 210, and the ribs 203 can be protrusions provided on the inner surface of the housing 210. When the lint filter 200 is in normal use, there is a certain gap between the blades 224 and the ribs 203.

[0041] In this embodiment, a first magnetic member 225 is disposed on the second end cover 222, and a second magnetic member 232 is disposed in the housing 210; an adsorption force is formed between the first magnetic member 225 and the second magnetic member 232. When the lint filter 200 is in normal use, the filter element 220 is fixed in the housing 210 by the adsorption force between the first magnetic member 225 and the second magnetic member 232.

[0042] When it is necessary to clean the lint accumulated inside the lint filter 200, the rotation speed of the drain pump 100 can be made greater than the preset value. At this time, the water flow through the filter element 220 increases, so that the filter element 220 overcomes the adsorption force between the first magnetic member 225 and the second magnetic member 232 and moves toward the drain pump 100, so that the blade 224 on the side wall 223 is close to the rib 203, and the drain pump 100 drives the filter element 220 to rotate. When the filter element 220 rotates, it can drive the lint in the washing water to move toward the inner wall of the housing 210, and the blade 224 and the rib 203 can grind the longer lint in the washing water into pieces, and the shredded lint can be discharged with the washing water without accumulating in the lint filter 200, so that the user does not need to clean the lint filter 200 regularly, which is conducive to improving the user experience.

[0043] When cleaning is completed and normal use is performed, the rotation speed of the drain pump 100 can be made lower than a preset value. At this time, the filter element 220 moves to the side away from the drain pump 100 under the action of the adsorption force between the first magnetic part 225 and the second magnetic part 232, so that the blade 224 is away from the rib 203, the filter element 220 is separated from the output shaft 110, and the lint filter 200 can filter the washing water normally.

[0044] In this embodiment, the preset value of the rotation speed of the drainage pump 100 can be set as needed.

[0045] It can be seen from the above description that the lint filter assembly 10 of this embodiment can achieve self-cleaning of the lint accumulated in the lint filter 200, without the need for the user to clean the lint filter 200 regularly, which is beneficial to improving the user experience.

[0046] Please continue to refer to Figure 1 and Figure 3 In a possible implementation, an assembly hole 111 is provided at one end of the output shaft 110 located in the cavity, and the filter element 220 is further provided with a rotating shaft 226. When the rotation speed of the drain pump 100 is greater than a preset value, the rotating shaft 226 is inserted into the assembly hole 111, thereby achieving the connection between the drain pump 100 and the filter element 220.

[0047] Optionally, in the first direction X, the rotating shaft 226 is directly opposite to the assembly hole 111. The assembly hole 111 is a spline hole, that is, a plurality of grooves are formed on the inner wall of the assembly hole 111; accordingly, a plurality of protrusions are provided on the outer circumference of the rotating shaft 226, and the number of the protrusions matches the number of the grooves in the assembly hole 111, so as to facilitate the clamping of the rotating shaft 226 in the grooves and improve the stability of the connection between the two.

[0048] Furthermore, the filter element 220 of the present embodiment includes a first end cover 221, a second end cover 222, and a side wall 223 located between the first end cover 221 and the second end cover 222, a plurality of blades 224 are located on the side wall 223, a rotating shaft 226 is passed through the first end cover 221 and the second end cover 222 along a first direction X, and at least a portion of the rotating shaft 226 is exposed on the side of the first end cover 221 facing the drain pump 100, thereby facilitating the connection between the drain pump 100 and the filter element 220.

[0049] Please continue to refer to Figure 2In a possible implementation, the side wall 223 of this embodiment includes a first side wall 2231 and a second side wall 2232 that are spaced apart, and a gap is formed between the first side wall 2231 and the second side wall 2232; that is, the side wall 223 on the filter element 220 is discontinuous. The plurality of blades 224 include a plurality of first blades 2241 disposed on the first side wall 2231 and a plurality of second blades 2242 disposed on the second side wall 2232, wherein the plurality of first blades 2241 are disposed at the water-facing end of the first side wall 2231, and the plurality of second blades 2242 are disposed at the water-facing end of the second side wall 2232. When the filter element 220 rotates, the first blade 2241 and the second blade 2242 can both push the wire scraps in the water onto the convex rib 203, thereby cooperating with the convex rib 203 to grind the wire scraps.

[0050] Furthermore, in this embodiment, a plurality of first blades 2241 and a plurality of second blades 2242 are staggeredly distributed along the axis of the filter element 220. The above arrangement not only ensures that blades 224 are provided at various positions on the filter element 220 along the first direction X, but also reduces the overall number of blades 224, thereby reducing the resistance encountered by the filter element 220 when rotating.

[0051] In a possible implementation manner, the second end cover 222 of this embodiment is further connected to a stop wall 227 on the side facing away from the first end cover 221. The stop wall 227 and the second end cover 222 together form a receiving space, and the first magnetic member 225 is disposed in the stop wall 227. In order to prevent the first magnetic member 225 from failing due to heat, this embodiment provides a first heat insulation layer 228 on the outside of the first magnetic member 225. The first heat insulation layer 228 completely covers the first magnetic member 225, thereby preventing the first magnetic member 225 from contacting with hot water.

[0052] The housing 210 of this embodiment is provided with an opening on one side away from the drain pump 100, and a knob cover 230 is detachably installed in the opening. The knob cover 230 and the housing 210 can be connected and fixed by a threaded connection; the knob cover 230 is provided with a knob at one end away from the drain pump 100, so that it is convenient for the user to open it. The knob cover 230 is connected with an extension tube 231, which is located in the accommodating cavity 214, and the extension tube 231 is sleeved on the outside of the stop wall 227. The extension tube 231 and the knob cover 230 together form a accommodating space, and the second magnetic member 232 is arranged in the extension tube 231. In order to prevent the second magnetic member 232 from failing due to heat, the second heat insulation layer 233 is provided on the outside of the second magnetic member 232 in this embodiment, and the second heat insulation layer 233 completely covers the second magnetic member 232, thereby preventing the second magnetic member 232 from contacting with hot water.

[0053] In a possible implementation manner, a plurality of water permeable holes 2211 are provided on the first end cover 221 of this embodiment. The water permeable holes 2211 can facilitate the passage of smaller wire scraps and prevent the shredded wire scraps from accumulating in the filter element 220 .

[0054] The filter element 220 of this embodiment is in a truncated cone shape, and in the direction away from the drain pump 100, the projected area of ​​the filter element 220 in the plane perpendicular to the first direction X gradually increases. The filter element 220 is arranged in a truncated cone shape, which can reduce the movement resistance of the filter element 220. When the speed of the drain pump 100 changes, the filter element 220 can be better moved in the housing 210, so as to be connected to or separated from the drain pump 100.

[0055] Please continue to refer to Figure 1 and Figure 3 In a possible implementation, a cavity is formed in the housing 210 of this embodiment, and the cavity includes an impeller cavity 211, a transition cavity 212, a filter element cavity 213 and a receiving cavity 214 which are sequentially connected along the first direction X. Among them, the output shaft 110 is located in the impeller cavity 211, and the drainage pump 100 also includes a motor 120 and a plurality of impellers 130. The motor 120 is connected to the output shaft 110 and is located outside the housing 210. The plurality of impellers 130 are sleeved on the output shaft 110 and arranged in the impeller cavity 211. The filter element 220 is located in the filter element cavity 213. The shape of the filter element cavity 213 is adapted to the rotary profile of the outer shape of the filter element 220 and is also truncated. The plurality of convex ribs 203 are all located on the inner wall of the filter element cavity 213.

[0056] In this embodiment, the diameter of the transition chamber 212 is smaller than the diameter of the impeller chamber 211 and the diameter of the filter element chamber 213. The first end cover 221 of the filter element 220 can be loosely matched with the transition chamber 212. When the filter element 220 rotates, the transition chamber 212 can also provide support for the filter element 220.

[0057] In one possible implementation, the spiral direction of the rib 203 of this embodiment is opposite to the direction in which the drain pump 100 drives the filter element 220 to rotate, so that when the filter element 220 rotates, it realizes a "scissor-type" structure together with the blade 224 on the filter element 220 to shred larger wire scraps.

[0058] The housing 210 of this embodiment is provided with a water inlet 201 and a drain port 202 connected to the cavity, the water inlet 201 is connected to the filter element cavity 213, and the drain port 202 is connected to the impeller cavity 211, so as to ensure that the washing water is discharged after being filtered by the filter element 220. Optionally, the axis of the water inlet 201 of this embodiment is perpendicular to the axis of the drain port 202.

[0059] Optionally, the first magnetic component 225 of the present embodiment may be a magnetic block, which includes an iron block, a cobalt block, a nickel block or a magnetic conductive metal alloy block; the second magnetic component 232 may be a magnet or an electromagnet.

[0060] Alternatively, the first magnetic member 225 may be a magnet or an electromagnet, and the second magnetic member 232 may be a magnetic block, which includes an iron block, a cobalt block, a nickel block, or a magnetically conductive metal alloy block.

[0061] Alternatively, the first magnetic member 225 and the second magnetic member 232 may both be magnets or electromagnets.

[0062] The above structures can all generate attraction between the first magnetic member 225 and the second magnetic member 232 , and can be specifically configured as needed.

[0063] Figure 4 This is a simplified structural diagram of a washing machine provided in one embodiment of the present application. Figure 4 This embodiment also provides a clothing processing device, including the above-mentioned lint filter assembly 10.

[0064] Specifically, the clothing processing device may be a washing machine or a washer-dryer, and the clothing processing device includes a housing 20, and a lint filter assembly 10 is disposed on a side of the housing 20 close to the bottom support foot, and the lint filter assembly 10 can filter and collect lint generated during the processing of clothing, and prevent the lint from being entangled on the impeller of the drainage pump during the drainage process. The lint filter of this embodiment can also realize self-cleaning of the internal accumulated lint, and the user does not need to clean the lint filter regularly, which is conducive to improving the user experience.
