Description

Technical Field

[0001] This invention relates to the field of washing machine technology, specifically to a lint filter device, and also to a washing machine having the lint filter device. Background Technology

[0002] As people's living standards continue to improve, washing machines have become one of the essential home appliances. Various types of washing machines have brought a lot of convenience to people's lives. However, washing machines produce lint and debris when washing clothes. In order to clean up the lint and debris and prevent them from sticking to the clothes again, lint filters are installed inside the washing machine.

[0003] Currently, lint filtering devices used in products mainly consist of two parts: a filter cover and a filter. The filter comprises a front cover and a rear cover. The filter cover is fixed to the inner wall of the tub with screws, and the filter is installed on the filter cover using a snap-fit ​​mechanism to collect lint. The lint filtering device collects lint and debris inside the filter. After washing clothes, the lint filtering device is removed, and the lint and debris inside the filter are cleaned.

[0004] In the existing technology, lint filter devices can only be used to collect lint, which has the problem of limited functionality.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a lint filter device. By setting a water outlet cavity on the filter cover and setting a water outlet channel connecting the outside of the filter cover and the water outlet cavity, the water outlet cavity can guide and collect the dehydration water flow, thereby enhancing the dehydration effect of the washing machine and enriching the function of the lint filter device.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A lint filter includes a filter cover, the top of which is provided with a water outlet cavity, and a water outlet channel is provided on one side of the water outlet cavity to connect the water outlet cavity with the outside of the filter cover.

[0009] In the above scheme, the water outlet chamber is connected to the outside of the inner tub. During spin-drying, the inner tub rotates, and the water flows upward along the conical inner tub wall. When it reaches the lower edge of the balance ring, the upward water flow is blocked by the balance ring and rotates around the inner tub wall in the upper area. The water outlet channel on the filter cover collects the washing water and guides the water flow into the water outlet chamber. Finally, the water flows into the spin-drying hole at the top of the inner tub and is discharged.

[0010] Furthermore, it also includes a flow guiding structure, which together with the top of the filter cover forms a water outlet channel;

[0011] Preferably, the flow guiding structure is a guide rib, which is inclined upward from the outside to the inside.

[0012] In the above design, a water outlet channel is formed between the guide rib and the top of the filter cover. The guide rib is inclined downward from the water inlet end of the water outlet cavity towards the outside of the filter cover, so that the water inlet end of the water outlet channel gradually expands from the inside to the outside, thereby enabling the water outlet channel to collect more washing water during the spin-drying process of the washing machine, further enhancing the spin-drying efficiency of the washing machine.

[0013] Furthermore, the water outlet chamber includes a first water outlet chamber and a second water outlet chamber, with the water inlet ends of the first water outlet chamber and the second water outlet chamber facing the two sides of the filter cover, respectively.

[0014] Preferably, the first water outlet chamber and the second water outlet chamber are separated by a vertical plate, and the vertical plate is provided with a connecting port connecting the first water outlet chamber and the second water outlet chamber.

[0015] The water outlet chamber includes a first water outlet chamber and a second water outlet chamber. The first water outlet chamber and the second water outlet chamber are respectively connected to the outside of the filter cover through water outlet channels. The water inlet ends of the water outlet channels of the first water outlet chamber and the second water outlet chamber face the two sides of the filter cover respectively.

[0016] Preferably, the first water outlet chamber and the second water outlet chamber are separated by a vertical plate, and the vertical plate is provided with a connecting port connecting the first water outlet chamber and the second water outlet chamber.

[0017] In the above scheme, the first and second water outlet chambers are respectively located on the left and right sides of the filter cover. The first and second water outlet chambers are separated by a vertical plate extending from the center of the inner side of the filter cover. Each of the first and second water outlet chambers has a water outlet channel communicating with the outer side of the filter cover on its side away from the vertical plate. The vertical plate has a connecting port that connects the first and second water outlet chambers, thus preventing excessive pressure on the vertical plate due to excessive water accumulation in one outlet chamber, thereby extending the service life of the device. For example, during the spin-drying process, if the inner tub of the washing machine rotates counterclockwise, the spin-drying water flows into the first water outlet chamber on the left and is discharged. If there is too much water in the first water outlet chamber, under pressure, some water flows from the connecting port on the vertical plate into the second water outlet chamber and is discharged.

[0018] Furthermore, a filter is installed in the middle of the filter cover, and a high-level filter is also installed on the filter cover between the filter and the filter chamber.

[0019] In the above solution, by setting up a high-water-level filter, the lint filtration device can also collect the lint floating on the upper layer of washing water during high-water-level washing. This ensures that the washing water in the inner tub is fully filtered, completely removing lint and overcoming the problem of poor washing effect caused by insufficient lint filtration during high-water-level washing in existing washing machines. At the same time, during the spin-drying process, the spin-drying water can flow through the high-water-level filter for filtration, preventing lint from entering the water outlet chamber and preventing blockage of the water outlet pipe.

[0020] Furthermore, the filter cover is provided with an installation port for installing a high-water-level filter;

[0021] The high-water-level filter includes a mounting part, which is embedded in the mounting port of the filter cover.

[0022] In the above scheme, the filter cover between the filter and the guide rib is provided with a recessed cavity that is recessed to the inside of the filter cover. An installation port that penetrates the cavity wall is opened on the cavity wall. The high water level filter is embedded in the cavity and assembled with the filter cover to seal the installation port.

[0023] Furthermore, the high-water-level filter also includes a filtration section, which includes a separately configured filtration chamber;

[0024] The filter section has connecting holes on its left and right side walls, respectively.

[0025] The front end of the filter section is also provided with a water outlet.

[0026] Furthermore, the connecting holes are located on the left and right side walls of the filter section, on the side away from the front end of the filter section;

[0027] Preferably, there are multiple connecting holes, which are distributed at intervals along the vertical direction.

[0028] In the above scheme, by setting the connecting hole on the side wall of the filter section away from the front end of the filter section, the washing water enters the filter chamber from the rear end of the filter section, flushing out all the original washing water in the filter chamber. This prevents some of the washing water in the filter chamber from remaining at the rear end of the filter chamber under the action of centrifugal force, thereby enhancing the filtration efficiency of the high water level filter. At the same time, by setting the connecting hole on the side wall of the filter section away from the front end of the filter section, the rotation radius of the connecting hole can also be increased, thereby accelerating the water filtration rate of the high water level filter.

[0029] Furthermore, a valve plate is also provided inside the filter chamber near the connecting hole;

[0030] The valve plate includes a left valve plate and a right valve plate, which are respectively fitted to the left inner wall and the right inner wall of the filter chamber, and are used to connect or disconnect the filter chamber and the corresponding connecting hole.

[0031] In the above scheme, the valve plate can be a soft rubber sheet. During the operation of the washing machine, one side of the valve plate undergoes elastic deformation under the force of the water flow, thus deflecting. The other side of the valve plate is blocked by the side wall of the filter section and does not deflect, guiding the water flow into the filter chamber and towards the outlet at the front end of the filter. One end of the valve plate is fixed to the inner wall of the rear end of the filter section, while the other end extends towards the front end of the filter chamber, serving as a free end. This allows the valve plate to not only control the opening and closing of the connecting hole but also guide the washing water flowing into the filter chamber, directing it towards the front end of the filter section, thereby further accelerating the filtration speed of the high-water-level filter.

[0032] Furthermore, a number of water-permeable holes are provided on the rear end face of the filter section;

[0033] Preferably, the permeable pores are evenly arranged on the rear end face of the filter section.

[0034] In the above solution, a gap is left between the rear end of the high water level filter and the inner barrel wall. By setting water-permeable holes on the rear end face of the filter section, the washing water in the filter chamber can flow out through the water-permeable holes. Since the diameter of the water-permeable holes is small, the lint cannot pass through. In this way, it can filter lint while allowing water to pass through, which helps to improve the filtration effect.

[0035] The present invention also provides a washing machine, which includes an inner tub, wherein the inner wall of the inner tub is provided with any of the above-described lint filter devices; the filter cover of the lint filter device is fastened to the inner tub wall, and the top of the inner tub is provided with a dewatering hole communicating with the water outlet chamber and the outside of the inner tub.

[0036] In the above scheme, the vertical plate on the filter cover extends from the inside of the filter cover to the inner barrel wall and leaves a gap between it and the inner barrel wall, which forms a communication port.

[0037] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0038] 1) This invention provides a water outlet cavity on the filter cover and a water outlet channel connecting the outside of the filter cover and the water outlet cavity, so that the water outlet cavity can guide and collect the dehydration water flow, thereby enhancing the dehydration effect of the washing machine and enriching the function of the lint filter device.

[0039] 2) This invention, by incorporating a high-level filter, allows the lint filtration device to collect floating lint from the upper layer of wash water during high-level washing, ensuring thorough filtration of the wash water in the inner tub and complete removal of lint. Simultaneously, during the spin-drying process, the spin-dry water flows through the high-level filter for further filtration, preventing lint from entering the outlet chamber and causing blockages in the outlet pipe.

[0040] At the same time, the present invention has a simple structure, significant effects, and is suitable for widespread use. Attached Figure Description

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

[0056] Example 1

[0057] like Figures 1 to 8 As shown in the figure, an embodiment of the present invention introduces a lint filtering device 200, including a filter cover 201 assembled with an inner barrel 100 and a filter 202 disposed on the filter cover 201. The inner barrel 100, the filter cover 201, and the filter 202 together form a hollow inner cavity 206. Alternatively, the inner barrel 100 and the filter cover 201 can together form the hollow inner cavity 206.

[0058] In this embodiment, a balance ring 101 is installed on the top of the inner tub 100 of the washing machine, and a dewatering hole 102 is provided on the top side of the inner tub 100. During the dewatering process, the inner tub 100 rotates, and the water flows upward along the conical inner tub 100 wall, reaching the lower edge of the balance ring 101. The upward water flow is blocked by the balance ring 101, and rotates around the inner tub 100 wall in the upper region. Under the action of centrifugal force, it is discharged from the dewatering hole 102.

[0059] Preferably, in this embodiment, the top of the filter cover 201 is provided with a water outlet cavity, and a flow guiding structure is provided on one side of the water outlet cavity. The flow guiding structure and the top of the filter cover together form a water outlet channel 208 connecting the water outlet cavity and the outside of the filter cover 201. The water in the inner barrel 100 flows into the water outlet cavity through the water outlet channel 208.

[0060] In this embodiment, the flow guiding structure is a guide rib 205, which extends from one side of the water outlet cavity to the outside of the filter cover 201. A water outlet channel 208 communicating with the water outlet cavity is formed between the guide rib 205 and the top of the filter cover 201. The guide rib 205 is designed to slope upwards from the outside in, causing the water inlet end of the water outlet channel 208 to gradually expand from the inside out. This allows the water outlet channel 208 to collect more washing water during the spin-drying process, further enhancing the spin-drying efficiency of the washing machine.

[0061] Preferably, in this embodiment, the water outlet chamber includes a first water outlet chamber 210 and a second water outlet chamber 211. The first water outlet chamber 210 and the second water outlet chamber 211 are respectively disposed on the left and right sides of the filter cover. The inner tub 100 of the washing machine is provided with dehydration holes 102 corresponding to the first water outlet chamber 210 and the second water outlet chamber 211, which are connected to the outside of the inner tub 100. The first water outlet chamber 210 and the second water outlet chamber 211 are respectively connected to the outside of the filter cover 201 through water outlet channels 208. The water inlet ends of the water outlet channels 208 of the first water outlet chamber 210 and the second water outlet chamber 211 are respectively facing the two sides of the filter cover 201.

[0062] In this embodiment, the first water outlet chamber 210 and the second water outlet chamber 211 are separated by a vertical plate 212 extending from the middle of the inner side of the filter cover 201. Water outlet channels 208 communicating with the outer side of the filter cover 201 are respectively provided on the side of the first water outlet chamber 210 and the side of the second water outlet chamber 211 away from the vertical plate 212. The vertical plate 212 is provided with a connecting port connecting the first water outlet chamber 210 and the second water outlet chamber 211, thereby preventing excessive pressure on the vertical plate 212 due to excessive water accumulation in one water outlet chamber, thus enhancing the service life of the device. For example, during the spin-drying process, if the inner tub of the washing machine rotates counterclockwise, the spin-drying water flows into the first water outlet chamber 210 on the left and is discharged. If there is too much water in the first water outlet chamber 210, under pressure, some water flows from the connecting port on the vertical plate 212 into the second water outlet chamber 211 and is discharged.

[0063] In this embodiment, a gap is left between the side of the vertical plate 212 near the wall of the inner barrel 100 and the inner barrel wall, and the gap forms a communication opening.

[0064] like Figures 2 to 5 As shown, in this embodiment, the filter cover 201 has water inlets 207 on its left and right sides that connect the inner barrel 100 and the hollow inner cavity 206. The water inlets 207 are located on both sides of the filter cover 201 above the filter 202, and the ends of the guide ribs 205 are respectively located at the upper middle position of the water inlets 207.

[0065] In this embodiment, a plurality of baffles 204 are provided at the water inlet 207, evenly arranged along both sides of the filter cover 201. By providing baffles 204 arranged at intervals at the water inlet 207, washing water enters the hollow inner cavity 206 through the gap between two adjacent baffles 204, which can prevent clothes in the washing water from entering the water outlet cavity and clogging the drain pipe of the washing machine, thus enhancing the user experience.

[0066] Example 2

[0067] like Figures 1 to 8 As shown, in this embodiment, a high-water-level filter 203 is provided on the filter cover 201 between the filter 202 and the guide rib 205. By providing the high-water-level filter 203, the lint filter device 200 can also collect the lint floating in the upper layer of washing water during high-water-level washing, ensuring that the washing water in the inner tub 100 is fully filtered and lint is completely removed. This overcomes the problem of poor washing performance caused by insufficient lint filtration during high-water-level washing in existing washing machines. Simultaneously, during the spin-drying process, the spin-drying water flows through the high-water-level filter 203 for filtration, preventing lint from entering the outlet chamber and causing blockage in the outlet pipe.

[0068] like Figure 3As shown, in this embodiment, the filter cover 201 between the filter 202 and the filter chamber is provided with a recessed cavity that is recessed into the hollow inner cavity 206. An installation port 209 is opened on the cavity wall that penetrates the cavity wall. The high water level filter 203 is embedded in the recessed cavity and assembled with the side of the filter cover 201 away from the hollow inner cavity 206, sealing the installation port 209. The cavity wall of the recessed cavity, the high water level filter 203 and the inner barrel 100 together form the hollow inner cavity 206.

[0069] Preferably, in this embodiment, the recessed cavity has a bottom wall that is disposed opposite to the wall of the inner barrel 100, and the mounting port 209 penetrates the bottom wall of the recessed cavity.

[0070] like Figure 6 and Figure 7 As shown, in this embodiment, the high-water-level filter 203 includes a front filter cover 2035 and a rear filter cover 2036 that are interlocked. The rear filter cover 2036 is located between the front filter cover 2035 and the wall of the inner barrel 100. The front filter cover 2035 and / or the rear filter cover 2036 are provided with filter recesses. The front filter cover 2035 and the rear filter cover 2036 are assembled to form a filter cavity 2032. The cavity wall of the recess, the inner barrel 100, the rear filter cover 2036 and / or the front filter cover 2035 together form a hollow inner cavity 206.

[0071] Preferably, the filter front cover 2035 matches the mounting port 209. The assembly of the filter front cover 2035 and the mounting port 209 seals the mounting port 209. The cavity wall of the recess, the inner barrel 100, the filter rear cover 2036 and the filter front cover 2035 together form a hollow inner cavity 206.

[0072] In this embodiment, the filter front cover 2035 and the filter rear cover 2036 are fastened together to form a filter section 2038. The filter section 2038 is hollow inside and is a filter cavity 2032. The filter section 2038 is provided with mounting parts 2037 at its upper and lower ends, which respectively cooperate with the upper and lower ends of the mounting port 209. The high water level filter 203 is embedded and installed at the mounting port 209 of the filter cover 201 through the mounting parts 2037.

[0073] Preferably, in this embodiment, the mounting part 2037 is a snap-fit, the lower end of the filter part 2038 is inserted into the mounting port 209, and the upper end of the filter part 2038 is snap-fitted into the mounting port 209. Preferably, the snap-fit ​​is disposed on the filter front cover 2035 and is integrally formed with the filter front cover 2035.

[0074] like Figure 6As shown, in this embodiment, the left and right side walls of the filter section 2038 are respectively provided with connecting holes 2031 for connecting the filter chamber 2032 and the hollow inner cavity 206; the front end of the filter section 2038 is also provided with a water outlet 2039 for connecting the filter chamber 2032 and the inner tub 100. During the operation of the washing machine, the washing water in the inner tub 100 flows into the hollow inner cavity 206 through the baffle 204, and the washing water in the hollow inner cavity 206 flows into the filter chamber 2032 through the connecting holes 2031. The washing water in the filter chamber 2032 flows out from the water outlet 2039 at the front end of the filter section 2038 and returns to the inner tub 100. A filter screen is provided on the inner side of the front end of the filter section 2038, and the lint in the washing water flowing through the water outlet 2039 is blocked by the filter screen and retained in the filter chamber 2032.

[0075] Preferably, in this embodiment, the connecting hole 2031 is disposed on the left and right side walls of the filter section 2038, on the side away from the front end of the filter section 2038. By disposing of the connecting hole 2031 on the side wall of the filter section 2038, away from the front end of the filter section 2038, washing water enters the filter chamber 2032 from the rear end of the filter section 2038, flushing out all the original washing water in the filter chamber 2032. This prevents some of the washing water in the filter chamber 2032 from remaining at the rear end of the filter chamber 2032 under the action of centrifugal force, thereby enhancing the filtration efficiency of the high-water-level filter 203. At the same time, by disposing of the connecting hole 2031 on the side wall of the filter section 2038, away from the front end of the filter section 2038, the rotation radius of the connecting hole 2031 can also be increased, thereby accelerating the water filtration rate of the high-water-level filter 203.

[0076] Preferably, in this embodiment, there are multiple connecting holes 2031, which are distributed at intervals along the vertical direction.

[0077] like Figure 7 As shown in this embodiment, a valve plate is also provided inside the filter cavity 2032, near the connecting hole 2031. The valve plate includes a left valve plate 2033 and a right valve plate 2034, which are respectively fitted to the left and right inner walls of the filter cavity 2032, and are used to connect or disconnect the filter cavity 2032 and the corresponding connecting hole 2031.

[0078] In this embodiment, both the left valve plate 2033 and the right valve plate 2034 are normally closed one-way valve plates. The left side of the left valve plate 2033 and the right side of the right valve plate 2034 are blocked by the left and right inner walls of the filter chamber 2032, respectively, so that the left valve plate 2033 and the right valve plate 2034 can only open to the inside of the filter chamber 2032. During the operation of the washing machine, one valve plate is deflected by the force of the water flow, while the other valve plate is blocked by the side wall of the filter section 2038 and does not deflect, thus introducing the water flow into the filter chamber 2032 and flowing to the outlet 2039 at the front end of the filter 202.

[0079] Preferably, in this embodiment, one end of the valve plate is fixed to the inner wall of the rear end of the filter section 2038, and the other end of the valve plate extends towards the front end of the filter chamber 2032 and is a free end. This allows the valve plate to not only control the opening and closing of the connecting hole 2031, but also to guide the washing water flowing into the filter chamber 2032, so that the washing water flows towards the front end of the filter section 2038, thereby further accelerating the filtration speed of the high water level filter 203.

[0080] For example, when the inner tub 100 of the washing machine rotates clockwise, a clockwise water flow is generated. The water flows from the left side of the filter cover 201 into the hollow inner cavity 206. The water flow in the hollow inner cavity 206 impacts the left valve plate 2033, causing the connecting hole 2031 on the left side of the filter section 2038 to open. The water flows into the filter 202 and continues to flow to the right side of the filter chamber 2032. At this time, the right valve plate 2034 installed on the filter rear cover 2036 closes, and the water flow cannot continue to flow to the right. It turns and flows back to the inner tub 100 through the filter screen at the front end of the filter section 2038, leaving the lint inside the filter 202. When the water flow rotates counterclockwise, it enters the high-water-level filter 203 from the right side. At this time, the right valve plate 2034 opens and the left valve plate 2033 closes.

[0081] Preferably, in this embodiment, a plurality of water-permeable holes 2030 are further provided on the rear end face of the filter section 2038, and the water-permeable holes 2030 are evenly arranged on the rear end face of the filter section 2038. In this embodiment, a gap is left between the rear end of the high-water-level filter 203 and the wall of the inner barrel 100. By providing water-permeable holes 2030 on the rear end face of the filter section 2038, the washing water in the filter chamber 2032 can flow out through the water-permeable holes 2030. Since the diameter of the water-permeable holes 2030 is small, lint cannot pass through. In this way, lint can be filtered while water can pass through, which helps to improve the filtration effect.

[0082] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
