Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of household appliances, and particularly to a washing machine. BACKGROUND

[0002] In the related art, a washing machine has become an essential household appliance in daily life. In order to prevent the washing machine drain pipe from being blocked, protect the drain device from foreign matter, and reduce pollution, a filter is added in the drain pipe of the washing machine to filter the water.

[0003] However, the current washing machine drain valve filter is designed with a grid or hole structure, and the structure is closed, so that the lint is easily entangled. Therefore, it is difficult to clean the washing machine drain valve filter without tools, which affects the user experience. CONTENT OF THE INVENTION

[0004] Therefore, the purpose of the present disclosure is to provide a washing machine to at least solve the technical problem that the cleaning process of the drain valve filter of the washing machine is not convenient in the prior art.

[0005] To achieve at least one of the above purposes, the present disclosure provides the following technical solutions:

[0006] The present disclosure provides a washing machine, which comprises:

[0007] a box body formed with a containing cavity;

[0008] a drum arranged in the containing cavity and comprising a washing machine inner drum and a washing machine outer drum;

[0009] a drain passage communicating the washing machine outer drum with a drain port of the washing machine, wherein a drain valve is arranged in the drain passage, and the drain valve is formed with a filter cavity, an inlet of the filter cavity communicates with an upstream section of the drain passage, and an outlet of the filter cavity communicates with a downstream section of the drain passage;

[0010] and a drain filter arranged in the filter cavity, wherein a water inlet of the drain filter corresponds to the inlet of the filter cavity, a water outlet of the drain filter corresponds to the outlet of the filter cavity, and the drain filter comprises:

[0011] a bottom wall provided with a bottom surface trapping portion;

[0012] a circumferential side wall arranged on the upper side of the bottom wall and provided with a side surface trapping portion;

[0013] The bottom surface complementing part and the side surface complementing part cooperate to form a water outlet of the drainage filter.

[0014] In the above technical solution, by optimizing the structure of the drainage filter arranged in the drainage channel of the washing machine, the bottom surface filtering column connected at one end to the opening part of the bottom wall of the drainage filter forms a bottom surface capturing part similar to a comb structure, which can not only quickly filter the lint and other foreign matters in the drainage of the washing machine, but also facilitate the user to quickly clean the bottom surface filtering column along the extension direction of the free end thereof.

[0015] In some embodiments, the opening part is a rectangular filtering opening formed along the length direction of the bottom wall, wherein one long side of the rectangular filtering opening forms the fixed side of the opening part.

[0016] In the above technical solution, fixing the bottom surface filtering column on one long side of the opening part can reduce the length of the bottom surface filtering column, thereby ensuring the structural reliability of the bottom surface capturing part, avoiding the breakage of individual bottom surface filtering columns, and not affecting the drainage filtering effect of the washing machine or increasing the use cost.

[0017] In some embodiments, each of the bottom surface filtering columns is arranged parallel to each other, and the extension direction of the bottom surface filtering column and the first direction of the straight line on which the fixed side is located form a preset included angle, wherein the first direction corresponds to the direction from the first short side plate to the second short side plate of the circumferential side wall, and the preset included angle ranges from 45° to 135°.

[0018] In the technical solution, considering that the opening part is a rectangular filtering opening arranged along the length direction of the bottom wall, when the included angle between the bottom filtering column and the fixed edge is too small or too large, the bottom filtering column arranged near the two ends of the long side of the opening part will form a large gap with the short side of the opening part, which will not only affect the appearance, but also affect the filtering effect of the drain filter. Even if the bottom filtering column is added on the long side or the short side of the opening part to fill the gap, the filtering effect is not good, and the efficiency of cleaning the hair and other foreign matters of the user is also affected. After the bottom filtering column and the fixed edge form a preset included angle within the above range, the filtering effect can be ensured, and the adhesion of the hair and other foreign matters on the adjacent bottom filtering column can be used to clean the hair and other foreign matters on the current bottom filtering column, so that the hair on the adjacent bottom filtering column is also adhered and cleaned at the same time, so that the cleaning process is more convenient and efficient, and the user experience is improved.

[0019] In some embodiments, each of the bottom filtering columns is arranged in layers to form at least two layers of bottom filtering layers arranged in up-down staggered arrangement at the opening part.

[0020] In the technical solution, the multi-layer bottom filtering layer design of the drain filter of the washing machine can realize multi-layer filtering and improve the filtering effect of the hair and other foreign matters.

[0021] In some embodiments, the peripheral side wall comprises: a first long side plate corresponding to the upper side of the fixed edge, a second long side plate opposite to the first long side plate, a first short side plate connected to the first end of the first long side plate and the first end of the second long side plate, and a second short side plate connected to the second end of the first long side plate and the second end of the second long side plate.

[0022] The first short side plate forms the mounting end face of the drain filter, and the second short side plate, the first long side plate and the second long side plate are respectively provided with the side surface trapping part.

[0023] In the technical solution, the trapping part is arranged on the three peripheral side walls and the bottom wall of the drain filter, so that multi-directional filtering is realized while the drain flow is ensured, and the user experience is not affected by the slow drain speed.

[0024] In some embodiments, the side surface trapping part comprises:

[0025] A first side filtering column arranged along the length direction of the second short side plate;

[0026] A second side filtering column arranged along the length direction of the first long side plate;

[0027] And a third side filtering column arranged along the length direction of the second long side plate.

[0028] In the technical scheme, the side surface capturing part on the corresponding side plate is designed as a side surface filtering column arranged at intervals, so that the side surface capturing part in the shape of a comb tooth structure is formed on the first long side plate, the second long side plate and the second short side plate respectively, and after the drain filter is removed, the lint and other foreign matters on the side surface capturing part can be easily cleaned.

[0029] In some embodiments, the drain filter is divided into a buffer area and a filtering area.

[0030] The water inlet of the drain filter corresponds to the buffer area.

[0031] In the technical scheme, the water inlet of the drain filter corresponds to the buffer area, so that the drain water does not directly wash the filtering area, and the filtering effect of the drain filter is affected.

[0032] In some embodiments, the buffer area is located at one end close to the first short side plate, and the filtering area is located at one end close to the second short side plate; the bottom surface capturing part is located in the filtering area, and the first side surface filtering column, the second side surface filtering column and the third side surface filtering column correspond to three sides of the filtering area; the first end of the first long side plate, the first short side plate and the first end of the second long side plate correspond to three sides of the buffer area.

[0033] In the technical scheme, the drain filtering area is divided into different functional areas, i.e. the filtering area and the buffer area, so that the drain water of the washing machine entering through the corresponding water inlet can be buffered first, so that the flow rate is not too large to wash the corresponding capturing part and affect the filtering effect; then the bottom surface capturing part on the bottom wall and the side surface capturing parts on the three corresponding side plates are used for multi-directional filtering and drainage, so that the filtering effect is ensured and the drain efficiency of the washing machine is improved.

[0034] In some embodiments, the filtering cavity has a first inlet corresponding to a first water inlet formed on the first long side plate; and / or,

[0035] The filtering cavity has a second inlet located on the upper side of the drain filter and corresponding to the buffer area of the drain filter.

[0036] In the technical solution, the structure of the filtering cavity is designed with corresponding inlets. For example, when one inlet is designed, a first water inlet can be formed at the first end of the first long side plate. At this time, the washing machine drainage is flushed to the inner side wall of the second long side plate through the first inlet of the filtering cavity, and the second long side plate is used to buffer the drainage, and then the drainage flows to the filtering area. Alternatively, the open surface (without a top wall) of the drainage filter can be directly used as a second water inlet, and the part of the second inlet of the filtering cavity corresponding to the corresponding buffer area of the bottom wall can also be used to achieve the buffering of the drainage, and then the drainage flows to the filtering area. In order to increase the drainage rate, two inlets can also be provided, that is, the filtering cavity has a first inlet and a second inlet, which correspond to the first water inlet and the second water inlet respectively.

[0037] In some embodiments, the opening part is a rectangular filtering opening formed along the length direction of the bottom wall, wherein a short side of the rectangular filtering opening forms a fixed side of the opening part.

[0038] In the technical solution, a short side of the opening part forms a fixed side of the opening part. In this design, the length of the bottom surface filtering column is relatively long, but a bottom surface trapping part similar to a comb structure can also be formed, thereby achieving the filtering effect of the washing machine drainage and facilitating the user to quickly remove the lint and other foreign matters during the cleaning of the drainage filter.

[0063] As part of the inventive concept of the present disclosure, before describing the embodiments of the present disclosure, the reasons for the inconvenience of cleaning the lint and other foreign matter on the existing washing machine drain filter in the related art are analyzed, and the technical solution of the embodiments of the present disclosure is obtained through reasonable analysis.

[0064] In the related art, a filter is added to the drain pipe of the washing machine to filter the washing machine drain to prevent the washing machine drain pipe from being blocked, to protect the drain device from blocking foreign matter, and to reduce pollution and other problems. However, the current washing machine drain valve filter design mostly uses a grid or hole structure design, and the structure is closed, and lint is easily entangled, which makes it difficult to clean it thoroughly without the aid of tools when disassembling the washing machine drain valve filter for cleaning, affecting the user experience.

[0065] Therefore, the present disclosure provides a washing machine, which optimizes the structure of a drain filter arranged in a washing machine drain passage, uses a bottom surface filter column connected at one end to an opening portion of a bottom wall of the drain filter, forms a bottom surface trapping portion similar to a comb tooth structure, and based on the drain filter, both filtering of lint and other foreign matter in the washing machine drain and facilitating the user to quickly clean the lint along the extension direction of the free end of the bottom surface filter column can be achieved.

[0066] The technical solutions of the embodiments of the present disclosure are described in detail below in combination with the drawings, and the technical features involved in the different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0067] As Figures 1-10As shown, an embodiment of the present disclosure provides a washing machine, which comprises a cabinet, a drum, a drain passage, and a drain filter 10. The cabinet is formed with a receiving cavity, and the drum is arranged in the receiving cavity and comprises a washing machine inner drum and a washing machine outer drum. The drain passage of the washing machine is communicated between the washing machine outer drum and a drain port of the washing machine, and a drain valve 20 is arranged in the drain passage. The drain valve 20 is formed with a filter cavity, an inlet of the filter cavity is communicated with an upstream section of the drain passage, an outlet of the filter cavity is communicated with a downstream section of the drain passage, and optionally, the outlet of the filter cavity is connected to the downstream section of the drain passage through a connecting piece 30, as shown in Figure 10 The drain filter 10 is arranged in the filter cavity, and a water inlet of the drain filter 10 corresponds to the inlet of the filter cavity, and a water outlet of the drain filter 10 corresponds to the outlet of the filter cavity. The drain filter 10 can be loaded into or taken out of the filter cavity through an inspection opening of the drain valve 20, and the inspection opening is blocked by a drain valve cover plate 202, as shown in Figures 8-10 .

[0068] The drain filter 10 is formed as a filter screen structure with an open top surface. Specifically, as shown in Figures 1-7 The drain filter 10 comprises a bottom wall 105 provided with a bottom surface trapping portion, and a peripheral side wall provided around the upper side of the bottom wall 105 and provided with a side surface trapping portion. The bottom surface trapping portion and the side surface trapping portion cooperate to form the water outlet of the drain filter 10. The bottom surface trapping portion comprises an opening portion 1052 formed on the bottom wall 105 along the length direction thereof, and bottom surface filter columns 1051 arranged in the opening portion 1052 in a spaced manner. The opening portion 1052 has two opposite side edges, one of which forms a fixing edge 10521 for fixing the bottom surface filter columns 1051, and the other of which forms a chip removal edge. The fixing end of the bottom surface filter columns 1051 is arranged on the fixing edge 10521 of the opening portion 1052, and the free end of the bottom surface filter columns 1051 extends towards the chip removal edge of the opening portion 1052, and a first gap is formed between the free end of the bottom surface filter columns 1051 and the chip removal edge of the opening portion 1052.

[0069] When the washing machine provided with the drain filter 10 is used to drain water, the water is first drained from the washing machine outer drum into the drain passage, then flows into the filter cavity through the filter cavity inlet of the drain valve 20, and then flows into the drain filter 10 through the water inlet of the drain filter 10. Based on the bottom surface trapping portion and the side surface trapping portion, the water flowing into the drain filter 10 is trapped with chips at the same time, and the water is quickly drained out.

[0070] In the embodiment, based on the bottom capturing part and the side capturing part, the drain filter 10 can filter the laundry machine drainage from the side and the bottom, ensuring the drainage rate of the drain filter 10. In addition, by optimizing the structure of the drain filter 10 arranged in the laundry machine drainage channel, the bottom filtering column 1051 connected to the opening part 1052 of the bottom wall 105 by a single end (the fixed end of the bottom filtering column 1051) forms a bottom capturing part similar to a comb structure, which can not only filter the lint and other foreign matters in the laundry machine drainage, but also facilitate the user to quickly clean the lint and other foreign matters along the extension direction of the free end of the bottom filtering column 1051.

[0071] It should be noted that the first gap between the free end of the bottom filtering column 1051 and the lint removal edge of the opening part 1052 can be designed according to actual needs, and the distance needs to meet the following conditions: it can ensure that it does not affect the filtering effect of the lint and other foreign matters in the drainage, and at the same time, it can facilitate the user to clean the filtered lint and other foreign matters. In addition, the number of bottom filtering columns 1051 arranged in the opening part 1052 needs to be designed in combination with the size of the opening part 1052, the thickness of the bottom filtering column 1051, and other factors, and the specific determination process is not described here.

[0072] In some alternative embodiments, as shown in Figure 1 and Figure 6 , the opening part 1052 is a rectangular filtering opening along the length direction of the bottom wall 105, and one long side of the rectangular filtering opening forms the fixed side 10521 of the opening part 1052. Fixing the bottom filtering column 1051 on one long side of the opening part 1052 can reduce the length of the bottom filtering column 1051, thereby ensuring the structural reliability of the bottom capturing part, avoiding the breakage of individual bottom filtering columns 1051, and not affecting the laundry machine drainage filtering effect, nor increasing the use cost.

[0073] In another alternative embodiment, the bottom filtering column 1051 can also be fixed on one short side of the opening part 1052. For example, the opening part 1052 is a rectangular filtering opening along the length direction of the bottom wall 105, and one short side of the rectangular filtering opening forms the fixed side of the opening part 1052. In this embodiment, one short side of the opening part 1052 forms the fixed side, and the length of the bottom filtering column in this design is relatively long, and the number of bottom filtering columns used is relatively small. This drain filter 10 also forms a bottom capturing part similar to a comb structure on the bottom wall 105, thereby achieving the filtering effect of the laundry machine drainage, and facilitating the user to quickly remove the lint and other foreign matters during the cleaning of the drain filter 10.

[0074] In some alternative embodiments, as shown in Figure 4 and Figure 7As shown, the bottom filter columns 1051 are arranged parallel to each other, and the extension direction of the bottom filter column 1051 forms a preset angle α with the first direction of the straight line where the fixed edge 10521 is located (i.e., corresponding to...). Figure 4 The angle between the directions shown by the two dashed lines in the middle), where the first direction corresponds to the direction along the first short side plate 104 to the second short side plate 103, and the preset angle α ranges from 45° to 135°.

[0075] Considering that the opening 1052 is a rectangular filter opening opened along the length of the bottom wall 105, when the included angle between the bottom filter column 1051 and the fixed side 10521 is too small or too large, the bottom filter column 1051 set near the two ends of the long side of the opening 1052 will form a large gap with the short side of the opening 1052. This will not only affect the aesthetics, but also affect the filtration effect of the drain filter 10. Even if a bottom filter column 1051 is added to the long or short side of the opening 1052 to fill the gap, the filtration effect will still be poor, and it will also affect the efficiency of users in cleaning foreign objects such as lint. In this embodiment, after the bottom filter column 1051 and the fixed edge 10521 form a preset included angle α within the above-mentioned range, the filtration effect can be guaranteed. At the same time, the lint and other foreign objects on the adjacent bottom filter columns 1051 can be adhered and removed simultaneously when cleaning the lint and other foreign objects on the current bottom filter column 1051. This makes the cleaning process more convenient and efficient and improves the user experience.

[0076] Optionally, to further reduce the gap formed between the bottom filter column 1051 and the short side of the opening 1052, the preset included angle can be optimized to a range of 85°-95°. Further optionally, when the bottom filter column 1051 and the fixed side 10521 form a preset included angle α, the free end of the bottom filter column 1051 can be offset towards the direction closer to the first short side plate 104, such as... Figure 7 As shown, the preset included angle α range is selected as the first included angle interval α1. The range of the first included angle interval α1 is 90°-95° ​​(including the endpoints of the interval), which can better meet the user's force application habits. Moreover, this angle can not only allow foreign objects such as hair to adhere better to the bottom filter column 1051, but also prevent some hair from leaking out in the first gap due to water flow.

[0077] In some alternative embodiments, considering that the bottom surface filter column 1051 arranged in a single layer may still have some lint and other foreign matter leaking out when filtering the washing machine drainage, the arrangement of the bottom surface filter column 1051 can be further optimized. For example, each bottom surface filter column 1051 is arranged in layers to form at least two layers of bottom surface filter layers arranged in an up-down staggered manner at the opening part 1052. In this embodiment, based on the multi-layer bottom surface filter layer design of the washing machine drainage filter 10, multi-layer filtration can be achieved to improve the filtration effect of lint and other foreign matter.

[0078] In some alternative embodiments, as shown in Figure 1 The peripheral side wall includes a first long side plate 102 corresponding to the upper side of the fixed edge 10521, a second long side plate 101 opposite to the first long side plate 102, a first short side plate 104 connected to the first end of the first long side plate 102 and the first end of the second long side plate 101, and a second short side plate 103 connected to the second end of the first long side plate 102 and the second end of the second long side plate 101. Among them, the first short side plate 104 forms the mounting end face of the drainage filter 10; the second short side plate 103, the first long side plate 102 and the second long side plate 101 are provided with side capture parts. In this embodiment, the peripheral side wall of the drainage filter 10 is enclosed by four side plates, and the mounting end face is formed on the side of the first short side plate 104, which can facilitate user operation when disassembling the drainage filter 10 in the filter cavity.

[0079] In addition, in order to ensure the smoothness of the drainage of the drainage filter 10, corresponding capture parts are arranged on three sides of the peripheral side wall of the drainage filter 10 and the bottom wall 105, so as to ensure the drainage flow and avoid affecting the user experience due to slow drainage speed while achieving multi-directional filtration.

[0080] In some alternative embodiments, as shown in Figure 1 The side capture part includes a first side filter column 1031 arranged in a staggered manner along the length direction of the second short side plate 103, a second side filter column 1021 arranged in a staggered manner along the length direction of the first long side plate 102, and a third side filter column 1011 arranged in a staggered manner along the length direction of the second long side plate 101. In this embodiment, the side capture part on the corresponding side plate is designed as a staggered side filter column, so that the side capture part on the first long side plate 102, the second long side plate 101 and the second short side plate 103 forms a comb-like structure, and the lint and other foreign matter on the side capture part can be easily cleaned after the drainage filter 10 is removed.

[0081] Further optionally, to further improve the filtering efficiency of the washing machine drainage, a first side filtering column 1031 can be arranged on the full plate body of the second short side plate 103, i.e., the full plate body of the second short side plate 103 is designed as a comb structure. This design makes full use of the space of the second short side plate 103, so that the second short side plate 103 can discharge as much water in the drainage filter 10 as possible.

[0082] In some optional embodiments, as shown in Figure 4 , the drainage filter 10 is divided into a buffer area and a filtering area, and the water inlet of the drainage filter 10 corresponds to the buffer area. In this embodiment, by corresponding the water inlet of the drainage filter 10 to the buffer area, the washing machine drainage is prevented from directly washing the filtering area, thereby affecting the filtering effect of the drainage filter 10.

[0083] Optionally, as shown in Figure 4 , the buffer area is located at one end close to the first short side plate 104, and the filtering area is located at one end close to the second short side plate 103; the bottom capturing part is located in the filtering area, the first side filtering column 1031, the second side filtering column 1021, and the third side filtering column 1011 correspond to three sides of the filtering area; the first end of the first long side plate 102, the first short side plate 104, and the first end of the second long side plate 101 correspond to three sides of the buffer area.

[0084] In this embodiment, by dividing the drainage filtering area into different functional areas, i.e., the filtering area and the buffer area, the washing machine drainage entering through the corresponding water inlet can be buffered first, so as to prevent the flow rate from being too large to wash the corresponding capturing part, thereby affecting the filtering effect; then the multi-directional filtering and drainage are performed through the bottom capturing part on the bottom wall 105 and the side capturing parts arranged on the three corresponding side plates, so as to improve the washing machine drainage efficiency while ensuring the filtering effect.

[0085] In some optional embodiments, as shown in Figure 5 , Figure 8 , Figure 9 , the filtering cavity has a first inlet 201, and the first inlet 201 corresponds to the first water inlet 1022 formed on the first long side plate 102; and / or, the filtering cavity has a second inlet, and the second inlet is located on the upper side of the drainage filter 10 and corresponds to the buffer area of the drainage filter 10.

[0086] In this embodiment, the structure of the filtering cavity is designed to correspond to the inlet. For example, when designing an inlet, the first water inlet 1022 can be arranged at the first end of the first long side plate 102, so that the washing machine drainage flows to the inner side wall of the second long side plate 101 through the first inlet 201 of the filtering cavity, and the second long side plate 101 buffers the washing machine drainage, and then the washing machine drainage flows to the filtering area, as shown in Figure 5 , Figure 8 , Figure 9As shown, the bottom wall 105 of the drainage filter 10 is rectangular in structure, the water inlet (first water inlet 1022) of the drainage filter 10 is arranged on the side surface, the bottom surface filter column 1051 is 90° with the first long side plate 102, the bottom surface filter column 1051 is connected to only one side (fixed side 10521) of the opening part 1052 of the bottom wall 105, and the other side is not connected; or, the open surface (without a top wall) of the drainage filter 10 can be directly used as a second water inlet, and the second inlet of the filter cavity corresponds to the part of the corresponding buffer area of the bottom wall 105, which can also achieve the buffering of the drainage, and then flows to the filtering area. The bottom wall 105 of the drainage filter 10 is rectangular in structure, the water inlet (second water inlet) of the drainage filter 10 is arranged on the open surface, and the side surface has no flow inlet at this time. The bottom surface filter column 1051 is 90° with the first long side plate 102, and the bottom surface filter column 1051 is connected to only one side (fixed side 10521) of the opening part 1052 of the bottom wall 105, and the other side is not connected.

[0087] In addition, in order to increase the drainage rate, two inlets can also be arranged, that is, the filter cavity has a first inlet 201 and a second inlet, which correspond to the first water inlet 1022 formed at the open surface of the drainage filter 10 and the second water inlet arranged on the side surface of the drainage filter 10, respectively.

[0088] The drainage filter 10 in the embodiment is surrounded by five surfaces to form a top surface open filter screen, that is, surrounded by a bottom wall 105 with a bottom surface trapping part and a peripheral side wall with a side surface trapping part, and divided into a filtering area and a buffer area along the length direction of the drainage filter 10, to achieve the buffering and filtering functions of the drainage entering the filter cavity. The lengths of the two side surface trapping parts (the side surface trapping part on the first long side plate 102 and the side surface trapping part on the second long side plate 101) arranged in the length direction of the drainage filter 10 are the same as the length of the bottom surface trapping part, and the width dimension of the bottom surface trapping part of the bottom wall 105 is not less than the height dimension of any side surface trapping part in the length direction of the drainage filter 10.

[0089] The bottom surface filter columns 1051 are parallel to each other, and the parallelism between the bottom surface filter columns 1051 is not necessarily in-plane parallelism, but can be three-dimensional parallelism, that is, multiple layers of filter layers are formed on the bottom wall 105 of the drainage filter 10; the side surface filter columns (including the first side surface filter column 1031, the second side surface filter column 1021, and the third side surface filter column 1011) are parallel to each other and perpendicular to the bottom wall 105, and multiple layers of filter layers can also be formed on the peripheral side wall of the drainage filter 10.
