[0002] Existing washing equipment primarily uses water flow to carry lint into a mesh collection device. During washing, the water flow trajectory is as follows: from the inner tub, it passes through the impeller mesh, gaps, or inner tub mesh to the bottom of the inner tub, and then flows upward from the bottom of the inner tub through the mesh collection device.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] The following is combined Figures 1 to 7 The present application describes a large particulate impurity collection device and a washing device for washing equipment.

[0042] See Figure 1 The first aspect of this application provides a large particulate impurity collection device for a washing machine, wherein the washing machine includes an inner tub (not shown) and a pulsator 1. The pulsator 1 is bolted to the bottom of the inner tub and is used to agitate the water flow for washing clothes or shoes. The large particulate impurity collection device 2 is detachably installed on the upper part of the pulsator 1 for collecting large particulate impurities mixed in with the water.

[0043] The present invention provides a large particle impurity collection device for washing equipment. By installing a large particle impurity collection device 2 on the impeller 1, large particle impurities can be collected, so that clothes or shoes will not be contaminated, and the inner tub and impeller 1 will not be damaged.

[0044] Specifically, during the washing cycle, large particles of impurities appearing in the inner tub can be collected into the large particle impurity collection device 2. After washing, the large particle impurity collection device 2 can be manually removed for cleaning, thus preventing clothing or shoes from being contaminated and avoiding damage to the inner tub and impeller 1. Large particles of impurities generally refer to large particles of sand, lint balls, and buttons that have fallen off clothing. Among them, large particles of impurities are defined as particles with a diameter of 5 mm or greater.

[0045] See Figure 1 In this embodiment, the washing equipment can be a washing machine or a shoe washing machine, and the inner tub is the existing inner tub. The top surface of the impeller 1 has a slot 11, into which the filter base plate 212 of the large particle impurity collection device 2 is inserted, so that the large particle impurity collection device 2 and the impeller 1 are connected and easy to disassemble.

[0046] Furthermore, the large particle impurity collection device 2 can be one, two, three, or four, and the specific number can be determined according to the needs.

[0047] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In the preferred embodiment of the large particle impurity collection device for the above-described washing equipment, the large particle impurity collection device 2 generally includes a filter body 21, a cavity 22, a water inlet structure 23, and a water outlet structure 24. The filter body 21 is detachably installed on the upper part of the impeller 1. The cavity 22 is disposed inside the filter body 21. The water outlet structure 24 is disposed at the bottom of the filter body 21 and communicates with the cavity 22. The water inlet structure 23 is disposed on the filter body 21 and communicates with the cavity 22. Water and large particle impurities enter the cavity 22 through the water inlet structure 23, where the large particle impurities are collected. Water is discharged into the inner tub through the water outlet structure 24. By configuring the filter body 21, cavity 22, water inlet structure 23, and water outlet structure 24, large particle impurities can be collected, preventing clothing and shoes from being contaminated and avoiding damage to the inner tub and impeller 1.

[0048] Continue reading Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In the preferred embodiment of the large particle impurity collection device for the washing equipment described above, the filter body 21 generally includes a filter housing 211 and a filter base plate 212. The filter housing 211 has an open opening 2111 at its bottom, and the interior of the filter housing 21 is a cavity 22. The filter base plate 212 is detachably connected to the bottom end of the filter housing 211 to seal the open opening 2111, and the filter base plate 212 is detachably mounted on the upper part of the impeller 1.

[0049] Specifically, the filter housing 211 is made of metal or hard plastic and is manufactured using a mold. The size of the opening 2111 is adapted to the size of the filter base plate 212. The rear end of the filter base plate 212 and the rear end of the filter housing 211 can be connected by a hinge 209, and the front end of the filter base plate 212 and the front end of the filter housing 211 can be connected by a snap-fit ​​210, making it easy to open the filter housing 211 and the filter base plate 212 to clean large particles of impurities.

[0050] Alternatively, the filter base plate 212 is not limited to engaging with the slot 11 on the impeller 1, but can also be connected by screws.

[0051] Furthermore, the shape of the filter base plate 212 is consistent with the shape of the raised top surface on the impeller 1. The filter base plate 212 is a trapezoidal plate, and the bottom surface of the filter box 211 is also trapezoidal, so as to adapt and connect with the filter base plate 212. The height of the filter box 211 can be set according to the actual situation without affecting the washing.

[0052] See Figure 6 In the preferred embodiment of the large particle impurity collection device for washing equipment described above, a water outlet structure 24 is provided on the filter bottom plate 212. By setting the water outlet structure 24, the water entering the cavity 22 can be discharged to form a water circulation and leave the large particle impurities in the cavity 22.

[0053] See Figure 6 In the preferred embodiment of the large particle impurity collection device for the washing equipment described above, the water outlet structure 24 generally includes multiple water outlet holes 241. These multiple water outlet holes 241 are equidistantly located on the filter base plate 212 and communicate with some through holes on the impeller 1, allowing water to be discharged into the inner tank through the water outlet holes 241. By providing multiple water outlet holes 241, water circulation is formed, and large particle impurities are collected within the cavity 22.

[0054] In this embodiment, a portion of the multiple water outlet holes 241 are opened on one side of the filter base plate 212, and another portion of the multiple water outlet holes 241 are opened on the other side of the filter base plate 212. All the multiple water outlet holes 241 are elongated or circular.

[0055] Furthermore, the water outlet rate of the water outlet structure 24 is equal to or greater than the water inlet rate of the water inlet structure 23, in order to avoid the problem of poor water circulation in the large particle impurity collection device 2.

[0056] See Figure 2 and Figure 3 In the preferred embodiment of the large particle impurity collection device for the washing equipment described above, the water inlet structure 23 generally includes a first water inlet component 231 and a second water inlet component 232. The first water inlet component 231 is located on one side of the filter housing 211 and communicates with the cavity 22, while the second water inlet component 232 is located on the other side of the filter housing 211 and also communicates with the cavity 22. By providing the first water inlet component 231 and the second water inlet component 232, water can enter the water both when the impeller 1 rotates clockwise and counterclockwise, thereby completely removing large particle impurities from the water without leaving any residue.

[0057] See Figure 2 , Figure 3 and Figure 7 In the preferred embodiment of the large particle impurity collection device for the washing equipment described above, the first water inlet assembly 231 generally includes a first opening 2311 and a first valve plate 2312. The first opening 2311 is located on one side of the filter housing 211, and the first valve plate 2312 is located inside the cavity 22. The lower edge of the first valve plate 2312 is connected to one side edge of the filter base plate 212, and the lower part of the first valve plate 2312 has a first bending portion 26. The first valve plate 2312 and the first opening 2311 are interference-fitted. When the impeller 1 rotates clockwise, the first valve plate 2312, under the force of the large particles and water, tilts along the first bending portion 26 towards the inside of the cavity 22, thereby opening the first opening 2311 to allow the large particles and water to enter the cavity 22. When the impeller 1 rotates counterclockwise, the first valve plate 2312, driven by the water inside the cavity 22, tilts outward along the first bend 26 to block the first opening 2311, allowing large particles of impurities and water to remain inside the cavity 22. The water is discharged into the inner tank through the outlet structure 24, while the large particles of impurities are collected inside the cavity 22. By providing the first opening 2311 and the first valve plate 2312, water mixed with large particles of impurities can enter the cavity 22 and be filtered, leaving the large particles of impurities inside the cavity 22.

[0058] Specifically, the shapes of the first opening 2311 and the first valve plate 2312 are adapted to each other, and the size of the first valve plate 2312 is larger than the size of the first opening 2311. In this way, the first valve plate 2312 can tilt into the cavity 22 but cannot extend out of the first opening 2311, thereby forming an interference fit and preventing the first opening 2311 from having a gap when the first valve plate 2312 is closed.

[0059] Continue reading Figure 2, Figure 3 and Figure 7 In this embodiment, the lower edge of the first valve plate 2312 and one side edge of the filter base plate 212 are connected by a first detachable structure 25. The first detachable structure 25 includes a first edge 251, a first mounting through hole 252, a first slot 253, and a first mounting protrusion 254. The first edge 251 is machined on the lower part of the first valve plate 2312, and its thickness is slightly greater than the upper thickness of the first valve plate 2312. There are two first mounting through holes 252, symmetrically located on the first edge 251. The first slot 253 is machined on one side edge of the filter base plate 212. There are two first mounting protrusions 254, symmetrically located inside the first slot 253.

[0060] Specifically, the dimensions of the first slot 253 and the first edge 251 are adapted so that the first edge 251 is inserted into the first slot 253, and the dimensions of the first mounting protrusion 254 and the first mounting through hole 252 are adapted and correspond so that the first mounting protrusion 254 is inserted into the first mounting through hole 252, so as to realize the detachable connection between the first valve plate 2312 and the filter base plate 212.

[0061] See Figure 7 In this embodiment, the first bending portion 26 includes a first groove 261 and a plurality of first through holes 262. The first groove 261, formed along the length of the first valve plate 2312, is machined above the first edge 251. The plurality of first through holes 262 are equidistantly machined on the first groove 261. The first groove 261 and the first through holes 262 reduce the supporting force on the first valve plate 2312, allowing the first valve plate 2312 to bend under water pressure, thus enabling the first valve plate 2312 to open and close. The first valve plate 2312 is made of elastic rubber or thermoplastic polyurethane.

[0062] Please refer to further reading Figure 2 , Figure 3 and Figure 7In this embodiment, in the preferred embodiment of the large particle impurity collection device for the washing equipment described above, the second water inlet assembly 232 generally includes a second opening 2321 and a second valve plate 2322. The second opening 2321 is located on the other side of the filter housing 211, and the second valve plate 2322 is located inside the cavity 22. The lower edge of the second valve plate 2322 is connected to the other edge of the filter base plate 212. The lower part of the second valve plate 2322 has a second bend 27, and the second valve plate 2322 and the second opening 2321 are interference-fitted. When the impeller 1 rotates counterclockwise, the second valve plate 2322, under the force of the large particle impurities and water, tilts along the second bend 27 towards the inside of the cavity 22, opening the second opening 2321 to allow the large particle impurities and water to enter the cavity 22. When the impeller 1 rotates clockwise, the second valve plate 2322, driven by the water inside the cavity 22, tilts outward along the second bend 27 to block the second opening 2321, allowing large particles of impurities and water to remain inside the cavity 22. The water is discharged into the inner tank through the outlet structure 24 to collect the large particles of impurities inside the cavity 22. By providing the second opening 2321 and the second valve plate 2322, water mixed with large particles of impurities can enter the cavity 22 for filtration, while the large particles of impurities are retained inside the cavity 22.

[0063] Please refer to further reading Figure 2 , Figure 3 and Figure 7 In this embodiment, the lower edge of the second valve plate 2322 and the other side edge of the filter base plate 212 are connected by a second detachable structure 28. The second detachable structure 28 includes a second edge 281, a second mounting through hole 282, a second slot 283, and a second mounting protrusion 284. The second edge 281 is machined on the lower part of the second valve plate 2322, and its thickness is slightly greater than the upper thickness of the second valve plate 2322. There are two second mounting through holes 282, symmetrically located on the second edge 281. The second slot 283 is machined on one side edge of the filter base plate 212. There are two second mounting protrusions 284, symmetrically machined on the inner side of the second slot 283.

[0064] Specifically, the second slot 283 and the second edge 281 are sized to fit together so that the second edge 281 is inserted into the first slot 253. The second mounting protrusion 284 and the second mounting through hole 282 are sized to fit together and correspond so that the second mounting protrusion 284 is inserted into the second mounting through hole 282, thereby enabling the second valve plate 2322 and the filter base plate 212 to be detachably connected.

[0065] See Figure 7In this embodiment, the second bending portion 27 includes a second groove 271 and a plurality of second through holes 272. Specifically, a second groove 271 is machined above the second edge 281 along the length of the second valve plate 2322, and a plurality of second through holes 272 are equidistantly machined on the second groove 271. The second groove 271 and the first through holes 272 reduce the supporting force on the second valve plate 2322, allowing the second valve plate 2322 to bend under water pressure, thus opening and closing the second valve plate 2322. The second valve plate 2322 is made of elastic rubber or thermoplastic polyurethane.

[0066] In the preferred embodiment of the large particle impurity collection device for washing equipment described above, the second valve plate 2322 and the first valve plate 2321 are opened alternately, which can realize the alternating water intake from both sides in order to complete the filtration of large particle impurities.
