Description

Technical Field

[0001] This utility model relates to the field of clothing processing technology, specifically providing a lint filter device and clothing processing equipment including the lint filter device. Background Technology

[0002] Existing clothing processing equipment mainly includes washing machines, washer-dryer combos, and dryers.

[0003] Taking a washer-dryer combo as an example, it can both wash and dry clothes. A washer-dryer combo mainly consists of a cabinet, a clothes handling drum installed inside the cabinet, and a drying system. The drying system is connected to the clothes handling drum and delivers hot air into it. During the drying mode, the airflow circulates between the clothes handling drum and the drying duct of the drying system. Lint from the clothes enters the drying duct with the airflow, where a lint filter is typically installed to filter and collect the lint.

[0004] Existing lint filter devices generally require users to manually clean the lint from the filter screen, which is inconvenient and results in a poor user experience.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that it is inconvenient to clean the lint on the filter screen of the existing lint filter device.

[0007] In a first aspect, the present invention provides a lint filtering device, comprising a housing, a first filter screen mounted on the housing, and an air blowing mechanism. The housing has an air inlet and an air outlet. The first filter screen is mounted at the air outlet or between the air inlet and the air outlet. The air blowing mechanism is capable of blowing air toward the first filter screen to clean the lint on the first filter screen.

[0008] In a preferred embodiment of the above-mentioned lint filtering device, the air blowing mechanism includes a piston and a channel disposed on the housing. The channel is located above the first filter screen and has an air jet port at a position corresponding to the first filter screen. The air jet port is positioned towards the first filter screen. The first end of the channel is blocked. The piston is inserted from the second end of the channel and can move towards the first end of the channel so that the gas in the channel is sprayed from the air jet port onto the first filter screen.

[0009] In the preferred embodiment of the above-mentioned lint filtering device, the channel includes a first channel and a second channel that are connected to each other, the air outlet is disposed in the first channel, the piston is installed in the second channel, and the cross-sectional area of ​​the first channel is smaller than the cross-sectional area of ​​the second channel.

[0010] In a preferred embodiment of the aforementioned lint filtering device, an air inlet is further provided on the channel, the air inlet being located between the air jet nozzle and the second end of the channel, and the air blowing mechanism further includes a one-way plug installed at the air inlet.

[0011] The one-way plug closes the air inlet as the piston moves toward the first end of the channel, preventing air from escaping from the air inlet.

[0012] The one-way plug opens the air inlet when the piston moves away from the first end of the channel, allowing air from outside the channel to enter the channel through the air inlet.

[0013] In the preferred embodiment of the above-mentioned lint filter device, the one-way plug includes a sealing part, a limiting part, and a connecting part. The sealing part is located inside the channel, the limiting part is located outside the channel, one end of the connecting part is fixedly connected to or integrally formed with the sealing part, and the other end of the connecting part passes through the air inlet and is fixedly connected to or integrally formed with the limiting part. The size of the connecting part is smaller than the size of the air inlet so that the connecting part can move freely within the air inlet. The sealing part can fit against the inner wall of the channel to seal the air inlet, and the limiting part can abut against the outer wall of the channel to prevent the limiting part from entering the inside of the channel.

[0014] In the preferred embodiment of the above-mentioned lint filtering device, the channel extends along the length direction of the first filter screen, and the number of air jets is multiple and they are distributed at intervals along the length direction of the channel.

[0015] In the preferred embodiment of the above-mentioned lint filter device, the air inlet is located at the first end of the housing along the X direction, and the air outlet is located on the first side of the first end and the second end of the housing.

[0016] In a preferred embodiment of the above-mentioned lint filtering device, the lint filtering device further includes a flow guiding member disposed within the housing. The flow guiding member is located near the second end of the housing and is opposite to the air inlet. The flow guiding member extends from the inner wall of the second side of the housing to the inner wall of the first side. The second side is disposed opposite to the first side. The flow guiding member is at least arc-shaped in the portion near the second side to guide the airflow toward the air outlet.

[0017] In a preferred embodiment of the above-mentioned lint filtering device, the lint filtering device further includes a second filter component installed at the air outlet. The second filter component is spaced apart from the first filter screen along the Y direction and is located outside the first filter screen. The second filter component can move relative to the housing along the X direction and be pulled out from the first end of the housing. A lint scraping structure is provided at the second end of the second filter component near the second end of the housing. The lint scraping structure protrudes from the second filter component toward the first filter screen.

[0018] In a second aspect, the present invention also provides a garment processing device, including the aforementioned lint filter.

[0019] With the above technical solution adopted, the lint filter of this utility model has an air blowing mechanism set on the outer shell of the lint filter. When it is necessary to clean the lint on the first filter screen, the user can blow air towards the first filter screen through the air blowing mechanism to blow the lint off the first filter screen. There is no need to clean the lint on the first filter screen by hand, which is more convenient and helps to improve the user experience.

[0020] Furthermore, the lint filter of this invention increases the velocity of the airflow ejected from the air outlet by making the cross-sectional area of ​​the first channel where the air outlet is set smaller than the cross-sectional area of ​​the second channel where the piston is installed, thereby improving the purging effect on the first filter screen.

[0021] Furthermore, the lint filter of this invention has an air inlet connected to the channel, and a one-way plug is installed at the air inlet. When the piston moves toward the first end of the channel, that is, when the piston is pushed toward the inside of the channel, the one-way plug closes the air inlet, preventing air in the channel from being discharged from the air inlet. In this way, all the air in the channel is discharged from the jet nozzle. When the piston moves away from the first end of the channel, that is, when the piston is pulled toward the outside of the channel, the one-way plug opens the air inlet, and air outside the channel can enter the channel through the air inlet. In this way, air entering the channel from the jet nozzle can be reduced or avoided.

[0022] Furthermore, the lint filter of this utility model is configured such that the one-way plug is composed of a sealing part, a limiting part and a connecting part, so that the one-way plug can automatically close and open the air inlet as the piston is pushed and pulled.

[0023] Furthermore, the lint filter of this utility model, by setting a flow guiding component, since the part where the flow guiding plate is connected to the inner wall of the second side of the shell is set as arc-shaped, will not form a dead corner, thus preventing lint from accumulating at this point.

[0024] Furthermore, the lint filtering device of this utility model provides a lint scraping structure on the second filter component and sets the second filter component to be movable relative to the outer shell, so as to facilitate the cleaning of lint between the first filter screen and the second filter component by the lint scraping structure.

[0040] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the embodiments described below are introduced in conjunction with a washer-dryer combo, the technical solution of the present invention is equally applicable to other types of clothing processing equipment, such as dryers.

[0041] It should be noted that in the description of this utility model, terms such as "left" and "right," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Furthermore, it should be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] Specifically, this utility model provides a washer-dryer combo machine, such as Figure 1 and Figure 2As shown, the washer-dryer of this utility model includes a housing 1, a clothes handling drum and a drying system installed inside the housing 1. The drying system can deliver hot air into the clothes handling drum to dry the clothes inside the drum.

[0044] The garment handling drum includes an outer drum 2 and an inner drum that is rotatably installed in the outer drum 2. The drying system is directly connected to the outer drum 2. The inner drum is used to hold clothes. The inner drum wall is provided with multiple through holes. When the drying mode is executed, the through holes can be used for ventilation. When the washing mode is executed, the through holes can be used for water flow.

[0045] Preferably, such as Figures 1 to 3 As shown, the drying system of this utility model includes a drying device, which includes a drying duct 31, a fan 32, and a heat pump module. The air inlet 3111 of the drying duct 31 is connected to one end of the outer cylinder 2, the air outlet 3121 of the drying duct 31 is connected to the air intake of the fan 32, and the air exhaust port of the fan 32 is connected to the other end of the outer cylinder 2. The evaporator 33 and the condenser 34 of the heat pump module are installed in the drying duct 31, with the evaporator 33 located upstream of the condenser 34.

[0046] The heat pump module also includes a compressor 35, a refrigerant pipe 38 connecting the evaporator 33 and the condenser 34 to the compressor 35, and a throttling element installed on the refrigerant pipe 38. The compressor 35 is located outside the drying duct 31.

[0047] For example, the drying air duct 31 is located above the outer cylinder 2. An air outlet is provided on the cylinder wall of the outer cylinder 2. The air outlet is close to the rear end of the outer cylinder 2. A window gasket 21 is installed at the cylinder opening of the outer cylinder 2. A return air port is provided on the window gasket 21. The air inlet port 3111 of the drying air duct 31 is connected to the air outlet through a corrugated pipe 36. The exhaust port of the fan 32 is connected to the return air port through a rubber pipe 37.

[0048] When the drying mode is executed, the fan 32 is started, and the humid air in the clothes handling drum is discharged through the air outlet and enters the drying air duct 31. After being condensed and dehumidified by the evaporator 33, it is heated by the condenser 34 and then flows back to the clothes handling drum from the return air outlet, completing one cycle.

[0049] It should be noted that this utility model is not limited to placing the drying air duct 31 above the clothes processing drum. For example, the drying air duct 31 can also be placed below or behind the outer drum 2. Such adjustments and changes to the specific installation position of the drying air duct 31 do not deviate from the principle and scope of this utility model. Of course, this utility model preferably places the drying air duct 31 above the clothes processing drum, which is beneficial for making full use of the space above the clothes processing drum and optimizing the layout.

[0050] Furthermore, it should be noted that those skilled in the art can also interchange the positions of the air outlet and the air return on the outer cylinder 2, so that the front end of the clothing treatment cylinder is the outlet and the rear end is the inlet. Alternatively, the air outlet can be set on the rear wall of the outer cylinder 2, etc. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should be limited to the protection scope of this utility model.

[0051] Furthermore, it should be noted that those skilled in the art can also connect the air intake of the fan 32 to the air outlet on the clothes processing drum, and then connect the exhaust port of the fan 32 to the air inlet 3111 of the drying duct 31. Alternatively, the drying duct 31 can be set into two sections, with the fan 32 installed between the two sections. Or, the fan 32 can be directly installed inside the drying duct 31, etc. Such adjustments and changes to the installation position of the fan 32 do not deviate from the principle and scope of this utility model and should all be limited to the protection scope of this utility model.

[0052] Furthermore, it should be noted that those skilled in the art can also omit the heat pump module in practical applications and use other types of dehumidifying and heating components to dehumidify and heat the airflow in the drying duct 31. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should be limited to the protection scope of this utility model.

[0053] Preferably, such as Figure 2 and Figure 3 As shown, the drying system of the washer-dryer of this invention also includes a lint filter 4, which is installed inside the drying air duct 31. The lint filter 4 filters the airflow entering the drying air duct 31. When the airflow passes through the lint filter 4, impurities such as lint carried by the airflow are intercepted by the lint filter 4, and the filtered lint is stored inside the lint filter 4. The lint filter 4 is preferably located upstream of the evaporator 33.

[0054] Preferably, such as Figure 3 As shown, the lint filter 4 of this utility model is detachably installed in the drying air duct 31. The drying air duct 31 is provided with a plug interface 3112, and the lint filter 4 is inserted into the drying air duct 31 through the plug interface 3112.

[0055] When it is necessary to clean the lint inside the lint filter 4, the lint filter 4 can be removed from the drying air duct 31. A pressure sensor can be installed upstream and downstream of the lint filter 4. The pressure difference between the two sensors determines whether the lint filter 4 needs cleaning. When cleaning is required, a prompt message can be sent to the user to remind them to clean the lint filter 4.

[0056] It should be noted that, in practical applications, those skilled in the art can place the connector 3112 on the side of the drying duct 31, or on the top surface of the drying duct 31, etc. Such adjustments and changes to the specific location of the connector 3112 do not deviate from the principle and scope of this utility model, and should all be limited to the protection scope of this utility model.

[0057] Preferably, such as Figure 1 and Figure 3 As shown, the drying air duct 31 is provided with an interface 3112 on the side facing the front panel of the housing 1, and the front panel is provided with a disassembly port 11 opposite to the interface 3112, and the lint filter device 4 can be pulled out from the disassembly port 11.

[0058] When it is necessary to clean the lint filter device 4, the user can pull out the lint filter device 4 from the disassembly port 11 on the front panel of the housing 1 for easy operation. After cleaning the lint filter device 4, the lint filter device 4 can be inserted again through the disassembly port 11.

[0059] Preferably, such as Figure 2 and Figure 3 As shown, the drying air duct 31 of this utility model includes a first air duct 311 and a second air duct 312 that are connected to each other. The first air duct 311 extends in the front-to-back direction, and the second air duct 312 extends in the left-to-right direction and is close to the front end of the clothes processing drum. The air inlet port 3111 of the drying air duct 31 is located in the first air duct 311, and the air outlet port 3121 of the drying air duct 31 is located in the second air duct 312. The lint filter device 4 is installed in the first air duct 311, and the evaporator 33 and condenser 34 of the heat pump module are installed in the second air duct 312.

[0060] For example, both the first air duct 311 and the second air duct 312 are located above the outer cylinder 2. The first air duct 311 is located at the upper left of the outer cylinder 2 and extends from the rear end of the outer cylinder 2 to the front end. An air inlet port 3111 is provided on the bottom wall at the rear end of the first air duct 311. An air outlet on the outer cylinder 2 is located directly below the air inlet port 3111. The air outlet is connected to the upper air inlet port 3111 through a corrugated pipe 36. An insertion interface 3112 is provided at the front end of the first air duct 311. The lint filter 4 is inserted into the first air duct 311 from the front end of the first air duct 311. The left end of the second air duct 312 is connected to the first air duct 311. An air outlet port 3121 is provided at the right end of the second air duct 312. A fan 32 is located at the upper right of the outer cylinder 2. The air inlet of the fan 32 is connected to the air outlet port 3121 on the second air duct 312.

[0061] It should be noted that, in practical applications, those skilled in the art may also place the first air duct 311 on the upper right of the clothing processing drum, and correspondingly place the fan 32 on the upper left of the clothing processing drum. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model, and should all be limited to the protection scope of this utility model.

[0062] Of course, in this utility model, the first air duct 311 is preferably located at the upper left of the outer cylinder 2. A detergent dispensing device is generally also provided at the upper left corner. In this utility model, the first air duct 311 is preferably located directly above the detergent dispensing device.

[0063] Preferably, such as Figure 4 As shown, the lint filter device 4 of this utility model includes a housing 41 and a first filter screen (not shown in the figure) installed on the housing 41. The housing 41 is provided with an air inlet 411 and an air outlet 412. The first filter screen is installed at the air outlet 412 or between the air inlet 411 and the air outlet 412.

[0064] For example, the first filter screen is installed at the air outlet 412, and the housing 41 is provided with a plurality of mounting posts 417 at the air outlet 412. The plurality of mounting posts 417 are distributed at intervals along the length direction (X direction in the figure) of the air outlet 412 and extend along the width direction (Z direction in the figure) of the air outlet 412. The mounting posts 417 are connected to the first filter screen and support the first filter screen.

[0065] It should be noted that, in practical applications, those skilled in the art can also extend the mounting post 417 along the length of the air outlet 412, or even omit the mounting post altogether. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should all be limited to the protection scope of this utility model. Furthermore, it should also be noted that, in practical applications, those skilled in the art can also install the first filter screen between the air inlet 411 and the air outlet 412 of the housing 41.

[0066] Preferably, such as Figure 4 As shown, the air inlet 411 is located at the first end of the housing 41 along the X direction, and the air outlet 412 is located on the first side between the first end and the second end of the housing 41.

[0067] For example, the outer shell 41 is a cuboid structure, with the X direction being the length direction of the outer shell 41. The first end of the outer shell 41 has an air inlet 411, and the second end of the outer shell 41 is sealed. The first side of the outer shell 41 between the first end and the second end has an air outlet 412. A first filter screen is installed at the air outlet 412. After the airflow enters the first air duct 311, it enters the outer shell 41 from the air inlet 411, and then exits from the air outlet 412 and enters the second air duct 312. When the airflow passes through the first filter screen, the lint carried by the airflow is intercepted by the first filter screen and remains inside the outer shell 41.

[0068] Preferably, such as Figures 4 to 9 As shown, the lint filter device 4 of this utility model also includes an air blowing mechanism disposed on the housing 41. The air blowing mechanism can blow air toward the first filter screen to clean the lint on the first filter screen.

[0069] By providing an air blowing mechanism on the housing 41 of the wire lint filter device 4, when it is necessary to clean the wire lint on the first filter screen, the user can blow air towards the first filter screen through the air blowing mechanism to blow the wire lint off the first filter screen, which helps to improve the user experience.

[0070] It should be noted that this utility model does not limit the specific structural form of the air blowing mechanism, as long as the air blowing mechanism can blow air toward the first filter screen and blow the lint off the first filter screen.

[0071] Preferably, such as Figures 4 to 9 As shown, the blowing mechanism of this utility model includes a piston 42 and a channel 413 disposed on the housing 41. The channel 413 is located above the first filter screen and has an air nozzle 414 disposed at a position corresponding to the first filter screen. The air nozzle 414 is disposed facing the first filter screen. The first end of the channel 413 is blocked. The piston 42 is inserted from the second end of the channel 413. The piston 42 can move toward the first end of the channel 413 so that the gas in the channel 413 is sprayed from the air nozzle 414 onto the first filter screen.

[0072] When the user needs to clean the lint on the first filter screen, the piston 42 can be pushed and pulled repeatedly. The piston 42 fits against the inner wall of the channel 413. When the piston 42 is pushed, it can compress the air in the channel 413, causing the air to be ejected from the jet nozzle 414 and sprayed onto the first filter screen to blow the lint off the first filter screen.

[0073] For example, channel 413 is disposed on the top of housing 41 and extends in the X direction. The first filter screen also extends in the X direction. Channel 413 is located above the first filter screen. Multiple air jets 414 are disposed on channel 413 and are spaced apart along the length of channel 413. One end of channel 413 near air inlet 411 of housing 41 is its first end, and channel 413 is closed at this end. The other end of channel 413 is its second end. One end of piston 42 is inserted into channel 413 through the second end of channel 413, and the other end of piston 42 is located outside channel 413. When piston 42 is pushed into channel 413, air inside channel 413 is sprayed from air jets 414 onto the first filter screen.

[0074] Preferably, such as Figures 4 to 9 As shown, the channel 413 provided on the housing 41 includes a first channel 4131 and a second channel 4132 that are connected. The jet port 414 is provided in the first channel 4131, and the piston 42 is installed in the second channel 4132. The cross-sectional area of ​​the first channel 4131 is smaller than the cross-sectional area of ​​the second channel 4132.

[0075] By making the cross-sectional area of ​​the first channel 4131 where the jet nozzle 414 is located smaller than the cross-sectional area of ​​the second channel 4132 where the piston 42 is installed, the speed of the airflow ejected from the jet nozzle 414 can be increased, thereby improving the purging effect on the first filter screen.

[0076] For example, the first channel 4131 and the second channel 4132 are distributed along the X direction. The first channel 4131 is close to the first end of the outer shell 41, and the second channel 4132 is close to the second end of the outer shell 41. The first channel 4131 is provided with a plurality of air nozzles 414 at the position corresponding to the first filter screen. The cross-section of the first channel 4131 and the second channel 4132 are both circular, and the inner diameter of the first channel 4131 is smaller than the inner diameter of the second channel 4132.

[0077] Preferably, such as Figures 6 to 10 As shown, the channel 413 of this utility model is also provided with an air inlet 415. The air inlet 415 is located between the jet nozzle 414 and the second end of the channel 413. The blowing mechanism also includes a one-way plug 43 installed at the air inlet 415. When the piston 42 moves toward the first end of the channel 413, the one-way plug 43 closes the air inlet 415 to prevent air in the channel 413 from being discharged from the air inlet 415. When the piston 42 moves away from the first end of the channel 413, the one-way plug 43 opens the air inlet 415 so that air outside the channel 413 can enter the channel 413 through the air inlet 415.

[0078] By providing an air inlet 415 communicating with the channel 413, and installing a one-way plug 43 at the air inlet 415, when the piston 42 moves toward the first end of the channel 413, that is, when pushing the piston 42 toward the inside of the channel 413, as... Figure 9 As shown, the one-way plug 43 seals the air inlet 415, preventing air in the channel 413 from escaping through the air inlet 415. This causes all the air in the channel 413 to be expelled through the exhaust port 414. When the piston 42 moves away from the first end of the channel 413, that is, when the piston 42 is pulled out of the channel 413, as... Figure 8 As shown, the one-way plug 43 opens the air inlet 415, allowing air outside the channel 413 to enter the channel 413 through the air inlet 415. This reduces or prevents air from entering the channel 413 from the jet nozzle 414.

[0079] For example, the air inlet 415 is located in the second channel 4132 and is connected to the second channel 4132.

[0080] Preferably, such as Figures 6 to 10 As shown, the one-way plug 43 of this utility model includes a sealing part 431, a limiting part 432, and a connecting part 433. The sealing part 431 is located inside the channel 413, the limiting part 432 is located outside the channel 413, one end of the connecting part 433 is fixedly connected to or integrally formed with the sealing part 431, and the other end of the connecting part 433 passes through the air inlet 415 and connects to the limiting part 432. The size of the connecting part 433 is smaller than the size of the air inlet 415, so that the connecting part 433 can move freely within the air inlet 415. The sealing part 431 can fit against the inner wall of the channel 413 to seal the air inlet 415, and the limiting part 432 can abut against the outer wall of the channel 413 to prevent the limiting part 432 from entering the inside of the channel 413.

[0081] like Figure 9 As shown, when the user pushes the piston 42 toward the inside of the channel 413, the pressure inside the channel 413 increases, forcing the one-way plug 43 to move toward the outside of the channel 413, so that the sealing part 431 of the one-way plug 43 fits against the inner wall of the channel 413, specifically against the inner wall of the second channel 4132, to seal the air inlet 415 and prevent air in the channel 413 from leaking from the air inlet 415.

[0082] like Figure 8 As shown, when the user pulls the piston 42 toward the outside of the channel 413, the pressure inside the channel 413 decreases, the sealing part 431 of the one-way plug 43 no longer adheres to the inner wall of the channel 413, opening the air inlet 415. Air from outside the channel 413 can enter the inside of the channel 413 through the air inlet 415. The limiting part 432 of the one-way plug 43 can abut against the outer wall of the channel 413 to prevent the one-way plug 43 from entering the inside of the channel 413 completely.

[0083] For example, the sealing part 431 is a sealing block, the limiting part 432 is a limiting block, the connecting part 433 is a connecting post, the air inlet 415 is circular, the outer diameter of the connecting post is smaller than the diameter of the air inlet 415, one end of the connecting post is integrally formed with the sealing block, and the other end of the connecting post is detachably fixedly connected to the limiting block. For example, a threaded hole is provided on the limiting block, and a thread that matches the threaded hole is provided on the connecting post so that the two are threadedly connected. The shape of the side of the sealing block connected to the connecting post is the same as the shape of the inner wall of the channel 413 so that the sealing block can fit better with the inner wall of the channel 413, thereby sealing the air inlet 415.

[0084] Preferably, such as Figures 4 to 9 As shown, the lint filter device 4 of this utility model also includes a flow guide member 45 disposed inside the housing 41. The flow guide member 45 is close to the second end of the housing 41 and is opposite to the air inlet 411 of the housing 41. The flow guide member 45 extends from the inner wall of the second side 416 of the housing 41 to the inner wall of the first side 41 of the housing 41. The second side 416 is disposed opposite to the first side. The flow guide member 45 is at least arc-shaped in the part close to the second side 416 to guide the airflow toward the air outlet 412.

[0085] After the airflow enters the housing 41 from the air inlet 411, part of the airflow flows to the position of the guide member 45 and flows towards the air outlet 412 under the guidance of the guide member 45. Since the part of the guide member 45 connected to the inner wall of the second side 416 of the housing 41 is set to be arc-shaped, no dead corner will be formed, and the accumulation of wire debris at this point can be avoided.

[0086] For example, the flow guiding member 45 is a flow guiding plate. The portion of the flow guiding plate that connects to the inner wall of the second side 416 of the outer casing 41 is arc-shaped, approximately 1 / 4 of a circle, while the portion of the flow guiding plate that connects to the inner wall of the first side 41 of the outer casing 41 is straight. Of course, in practical applications, the entire flow guiding plate can also be arc-shaped.

[0087] Preferably, such as Figure 4 and Figure 12 As shown, the lint filter device 4 of this utility model also includes a second filter assembly, which is also installed at the air outlet 412. The second filter assembly and the first filter screen are spaced apart along the Y direction and located outside the first filter screen. Wherein, the Y direction is the width direction of the outer shell 41.

[0088] In other words, along the direction of airflow, the second filter component is located downstream of the first filter screen. The airflow first passes through the first filter screen for filtration, and then passes through the second filter component for secondary filtration, resulting in a better filtration effect.

[0089] Preferably, such as Figure 4 and Figure 12 As shown, the second filter assembly of this utility model includes a second filter frame 44 and a second filter screen installed on the second filter frame 44.

[0090] The second filter frame 44 is vertically arranged and is used to support and fix the second filter screen, which is used to filter impurities such as lint carried by the airflow. The mesh size of the second filter screen is preferably greater than that of the first filter screen.

[0091] It should be noted that, in practical applications, those skilled in the art may also omit the second filter frame 44 and directly fix the second filter to the outer casing 41, etc. Such adjustments and changes to the specific structural form of the second filter component do not deviate from the principle and scope of this utility model and should be limited to the protection scope of this utility model.

[0092] In addition, it should be noted that, in practical applications, those skilled in the art can configure the second filter frame 44 and the outer shell 41 as a fixed connection or as an integrally formed piece.

[0093] Preferably, such as Figure 4 , Figure 11 and Figure 12 As shown, the second filter assembly of this utility model can move relative to the housing 41 in the X direction and be pulled out from the first end of the housing 41. A lint scraping structure 441 is provided at the second end of the second filter assembly near the second end of the housing 41. The lint scraping structure 441 protrudes from the second filter assembly toward the first filter screen.

[0094] For example, the lint scraping structure 441 is disposed on the second filter frame 44 and located at the second end of the second filter frame 44 (the end near the second end of the housing 41). The housing 41 is provided with a first slot 418 and a second slot (not shown in the figure). The first slot 418 and the second slot are disposed opposite to each other along the Z direction, which is the height direction of the housing 41. The first slot 418 is located directly below the second slot. The first ends of the first slot 418 and the second slot (the ends near the first end of the housing 41) are open, allowing the second filter frame 44 to be opened from the first slot. The first end of the slot 418 and the second slot is inserted, and the bottom and top of the second filter frame 44 are respectively inserted into the first slot 418 and the second slot. The first end of the second filter frame 44 is provided with a handle 442, which makes it easy for the user to pull the second filter frame 44 out of the first slot 418 and the second slot, thereby removing the second filter assembly from the housing 41 and making it easy to clean the second filter. When the second filter frame 44 is pulled outward, the lint scraping structure 441 on the second filter frame 44 can scrape off the lint located between the first filter and the second filter assembly.

[0095] It should be noted that this utility model does not limit the specific structural form of the wire scraping structure 441. For example, it can be set as a scraping plate, scraping ribs, or brush.

[0096] Preferably, such as Figure 12 As shown, the lint removal structure 441 on the second filter frame 44 is a flexible strip extending along the Z direction. The flexible strip can be made of rubber.

For example, any of the claimed embodiments in the claims of this application can be used in any combination.

[0098] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
