Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing, and specifically provides a clothing processing device with a drying function. Background Art

[0002] Currently, many clothing processing devices have a drying function, such as dryers and washer-dryers. Taking a washer-dryer as an example, the washer-dryer housing is provided with an outer drum, an inner drum, and an air duct. The inner drum is used to hold clothing and is rotatably disposed within the outer drum. The two ends of the air duct are respectively connected to the outer drum to form an air flow passage between the air duct and the outer drum. A fan is provided within the air duct to facilitate air flow. The air duct is also provided with a device such as a heat pump that can heat and dehumidify the air within the air duct to ensure that the air entering the outer drum through the air duct is dry and hot air that can dry the clothing. During the drying process, the friction between the clothing and the inner drum generates lint. These lint move with the flowing air in the air duct and adhere to certain components of the fan and heat pump (such as the condenser) within the air duct, reducing drying efficiency, prolonging drying time, and increasing power consumption.

[0003] To prevent the aforementioned adverse effects of lint, technicians in this field have installed a lint filter within the washer-dryer's air duct. This filter completely covers the cross-section of the duct. When lint moves with the air to the filter, it is collected by the filter, preventing it from adhering to the fan and heat pump components (such as the condenser) within the duct. While the filter can collect lint, the air flowing through it inevitably increases air flow resistance, which affects drying efficiency and results, while also prolonging drying time.

[0004] Therefore, the art needs a new clothes processing device with a drying function to solve the above problems. Summary of the Invention

[0005] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that a lint filter is provided in an air duct of an existing laundry processing device with a drying function, thereby affecting the drying efficiency and drying effect and prolonging the drying time, the present invention provides a laundry processing device with a drying function, the laundry processing device comprising a housing, an outer drum, an inner drum and a lint collection device, wherein the outer drum is provided in the housing, the inner drum is used to accommodate laundry and is rotatably provided between the outer drum and the inner drum, the lint collection device comprising an air introduction member, a lint collection assembly and an air driving assembly, the air introduction member being connected to the outer drum, at least a portion of the air introduction member extending into the outer drum, and an air inlet portion being formed on the portion of the air introduction member extending into the outer drum, the air introduction member being in communication with the lint collection assembly, and the lint collection assembly being formed with an exhaust portion, the air driving assembly being capable of driving air flow on a side of the exhaust portion away from the lint collection assembly so that air from the outer drum flows sequentially through the air introduction member and the lint collection assembly and is discharged from the lint collection assembly through the exhaust portion.

[0006] Through such an arrangement, on the one hand, the lint collection device of the present invention collects lint by sucking the air in the outer drum into the lint collection device through negative pressure. The lint collection device does not need to completely cover the cross-section of the air duct like a lint filter. On the other hand, the lint collection device is set outside the inner drum. The above two factors avoid a significant increase in the air flow resistance in the air flow path formed between the outer drum and the air duct during the drying process due to the collection of lint, and to a certain extent avoid the influence of resistance on drying efficiency, drying effect, and extension of drying time.

[0007] In the preferred technical solution of the above-mentioned clothing processing equipment, the air introduction component is an air introduction pipe, and the air introduction pipe is connected to the lint collection assembly through a first opening formed thereon, and the air intake part includes a first air inlet, a second air inlet and a third air inlet formed on the pipe wall of the air introduction pipe, and the first air inlet, the second air inlet and the third air inlet are arranged in sequence along the gas flow direction in the air introduction pipe and the opening area decreases in sequence.

[0008] Through such a setting, since the air flowing through the outer drum during the drying process actually mainly flows through the inner drum, the first air inlet and the second air inlet can still take in more air per unit time under relatively small negative pressure, thereby avoiding affecting the air intake efficiency and thus avoiding affecting the lint collection efficiency.

[0009] In the preferred technical solution of the above-mentioned clothing processing equipment, the lint collection assembly includes a lint collection barrel and a filter screen, the lint collection barrel is connected to the air introduction component through a second opening formed thereon, the exhaust part is an exhaust port formed on the lint collection barrel, and the filter screen cover is arranged on the exhaust port.

[0010] Through such an arrangement, the lint can be collected by the lint collection drum, and even if the lint cannot be completely collected by the lint collection drum, the filter can block and collect the lint, and the lint filtering effect is better.

[0011] In a preferred technical solution of the above-mentioned clothing processing device, the second opening is a circular opening, the inner cavity of the lint collecting cylinder is a cavity with a variable diameter, and the diameter of at least a part of the inner cavity is larger than the diameter of the second opening.

[0012] Through such an arrangement, when the air flows through the inner cavity of the wire scrap collection barrel, when the air flows to the part with a diameter larger than the diameter of the second opening, the air pressure becomes lower due to the increase in diameter, and some larger wire scraps can fall into the part with a diameter larger than the diameter of the second opening, thereby realizing the collection of wire scraps by the wire scrap collection barrel.

[0013] In the preferred technical solution of the above-mentioned clothing processing equipment, the air drive assembly includes an air outlet component, a fan and a motor, the air outlet component is formed with an air outlet portion and a third opening connected to the inner cavity of the air outlet component, the air outlet component is connected to the exhaust portion of the lint collection component through the third opening, the fan is arranged in the inner cavity of the air outlet component, the motor is arranged outside the air outlet component and connected to the fan, and the motor can drive the fan to rotate.

[0014] Through such an arrangement, that is, by arranging the air drive assembly to include an air outlet component and arranging the fan in the inner cavity of the air outlet component, the negative pressure formed by the rotation of the fan can be fully utilized by the lint collection device; in addition, the air outlet portion allows the air in the air outlet component to flow out, avoiding the air in the air outlet component from being unable to flow out and generating noise.

[0015] In a preferred technical solution of the above-mentioned clothes processing device, there are two air outlet parts, the two air outlet parts are arranged opposite to each other, and both of the two air outlet parts are connected to the outer drum.

[0016] Through such an arrangement, that is, the number of air outlet parts is two, the amount of air outlet per unit time is greater, thereby making the amount of air flowing through the lint filtering device per unit time greater, thereby improving the lint collection efficiency; in addition, the two air outlet parts are arranged opposite to each other, which is more convenient for the outflow of air in the inner cavity of the air outlet component; in addition, both outlet parts are connected to the outer drum, so that the air can flow back into the outer drum after passing through the lint filtering device, and during the washing process of the washer-dryer, the water in the outer drum can also flow back into the outer drum after flowing into the lint filtering device, and the water in the outer drum will not be lost.

[0017] In the preferred technical solution of the above-mentioned clothing processing equipment, the fan is a centrifugal fan, and a fourth opening is further formed on the air outlet component. The fan is arranged close to the fourth opening, and the third opening and the fourth opening are arranged opposite to each other along the axial direction of the centrifugal fan and are located in the middle of the air outlet component. The inner cavity of the air outlet component gradually shrinks from the middle along the first direction and the second direction respectively, so that the air outlet component forms two shrinking ends, and the two air outlet parts are respectively arranged on the two shrinking ends, wherein the first direction is opposite to the second direction, and the first direction and the second direction are both perpendicular to the axial direction of the centrifugal fan.

[0018] Through such an arrangement, since the air inlet direction of the centrifugal fan is axial and the air outlet direction is circumferential, it is possible to facilitate air intake and air outlet when the fan is working, thereby reducing the resistance during the air intake and air outlet process, and facilitating the air flow through the air outlet component. In addition, the inner cavity of the air outlet component gradually shrinks from the middle along the first direction and the second direction respectively, so that the air outlet component forms two shrinking ends, and the two air outlet parts are respectively arranged on the two shrinking ends, so that the air entering from the third opening encounters less resistance in the process of flowing out of the air outlet component under the action of the centrifugal fan, and is gradually guided to the air outlet part.

[0019] In a preferred technical solution of the above-mentioned clothes processing apparatus, the air driving assembly further includes a sealing member, and the sealing member is covered on the fourth opening and is capable of sealing the fourth opening.

[0020] By such an arrangement, i.e. providing a sealing member, water cannot enter the position where the motor is located during the washing process, thereby preventing the motor from being damaged or leaking electricity due to water ingress.

[0021] In a preferred technical solution of the above-mentioned clothing processing apparatus, the air introduction member is detachably connected to the outer drum and the lint collecting assembly respectively, and the lint collecting assembly and the air outlet member are integrally provided.

[0022] Through such an arrangement, on the one hand, the air introduction component can be removed from the outer cylinder, which is convenient for the user to clean and replace the air introduction component; on the other hand, the lint collection assembly can be removed from the air introduction component to clean the lint in the lint collection assembly. That is to say, when the lint in the lint collection assembly needs to be cleaned, there is no need to disassemble the air introduction component, which is very convenient; finally, the lint collection assembly and the air outlet component are arranged as one, so that each time the lint collection assembly is cleaned, the lint collection assembly and the air outlet component can be removed together, which is convenient for the user to observe whether there is lint that has not been blocked by the filter and has entered the air outlet component, so that the user can clean the air outlet component in time while cleaning the lint collection assembly, avoiding long-term accumulation of lint in the air outlet component, thereby avoiding entanglement of lint with the fan and damaging the fan.

[0023] In a preferred technical solution of the above-mentioned clothing processing device, the clothing processing device is a washer-dryer or a clothes dryer. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] It should be noted that in the description of the present invention, terms such as "center," "upper," "lower," "inner," "outer," "front," "rear," "axial," and "circumferential" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element described must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0034] Those skilled in the art will appreciate that the laundry processing device with a drying function of the present invention may be a washer-dryer, a clothes dryer, or the like. Such adjustments and changes to the specific type of laundry processing device do not constitute limitations on the present invention and should be within the scope of protection of the present invention. The following describes the technical solution of the present invention in detail using a washer-dryer as an example.

[0035] The washer-dryer includes a housing, an outer drum, an inner drum, an air duct, a fan, and a heat pump system. The outer drum, inner drum, and air duct are all disposed within the housing. The inner drum is used to hold clothes and is rotatably disposed within the outer drum. The air duct is connected to the outer drum at both ends, with the first end (i.e., the air inlet end) of the air duct communicating with the front of the outer drum, and the second end (i.e., the air outlet end) of the air duct communicating with the rear of the outer drum. The fan is disposed within the air duct. Air within the air duct enters the outer drum through the air outlet end of the air duct and then enters the air duct from the outer drum through the air inlet end of the air duct. In other words, an air flow path is formed between the air duct and the outer drum. The heat pump system includes an evaporator, a condenser, and a compressor connected to each other. The evaporator and condenser are disposed sequentially within the air duct along the direction of air flow, while the compressor is disposed outside the air duct. The condenser heats the air, while the evaporator dehumidifies the air. In other words, the evaporator and condenser convert the air within the air duct into hot, dry air for supply to the outer drum to dry the clothes.

[0036] It should be noted that the above only describes one possible scenario of the basic structure of the washer-dryer. Those skilled in the art can flexibly adjust the basic structure of the washer-dryer in actual applications. For example, those skilled in the art can adjust the specific connection position of the air duct and the outer cylinder; secondly, the device for heating and dehumidifying the air can also use a heater and a condenser, wherein the heater can heat the air and the condenser can dehumidify the air; in addition, the specific air flow path can also be adjusted. In the washer-dryer described above, the air forms a circulating air flow path between the outer cylinder and the air duct, but in fact, the air flow path can also be set to flow from outside the box through the outer cylinder and the air duct in sequence, and then be directly discharged from the air duct to the outside of the box. Those skilled in the art can understand that such adjustments and changes to the basic structure of the washer-dryer do not constitute limitations on the present invention and should be limited within the scope of protection of the present invention.

[0037] The washer-dryer also includes a lint collector. The washer-dryer operates in two processes: washing and drying. During the drying process, the lint collector allows air within the outer drum to flow through the lint collector to collect lint. Therefore, any subsequent description of the air flow through the lint collector occurs during the drying process.

[0038] like Figure 1 and 2 As shown, the lint collection device 2 includes an air introduction component 21, a lint collection assembly 22 and an air driving component 23. The air introduction component 21 is connected to the outer cylinder 1. The outer cylinder 1 is provided with a mounting hole 1a. The air introduction component 21 is inserted into the outer cylinder 1 through the mounting hole 1a. At least a portion of the air introduction component 21 extends between the outer cylinder 1 and the inner cylinder, and an air intake portion 21a is formed on the portion of the air introduction component 21 extending into the outer cylinder 1. The air introduction component 21 is connected to the lint collection assembly 22. The lint collection assembly 22 is formed with an exhaust portion 221b. When the air driving component 23 is started, it can drive the air flow of the exhaust portion 221b away from the side of the lint collection assembly 22, so that the air around the air introduction component 21 in the outer cylinder 1 flows into the air introduction component 21 due to negative pressure, and then flows into the lint collection assembly 22, and is discharged from the lint collection assembly 22 from the exhaust portion 221b. In the process of air flowing through the lint collection assembly 22, the lint collection assembly 22 can collect lint in the air.

[0039] It should be noted that the outer cylinder 1 can be a cylindrical outer cylinder 1; the outer cylinder 1 can also include a cylindrical body and an additional structure provided on the cylindrical body, and the inner cavity of the cylindrical body and the inner cavity of the additional structure are communicated with each other. In this case, the mounting hole 1a of the air introduction member 21 can be formed on the cylindrical body or on the additional structure ( Figure 1 This is the case shown in FIG), it is also possible that a portion of the mounting hole 1a is formed on the cylindrical body and the other portion is formed on the additional structure.

[0040] In a more specific possible scenario, a portion of the air introduction component 21 is located inside the outer cylinder 1, and the other portion of the air introduction component 21 and the lint collection component 22 are both located outside the outer cylinder 1 and are in communication with each other, and the air drive component 23 is also located outside the outer cylinder 1; in another more specific possible scenario, the entire air introduction component 21 is located inside the outer cylinder 1, the lint collection component 22 is located outside the outer cylinder 1, and the air drive component 23 is also located outside the outer cylinder 1; in yet another more specific possible scenario, the entire air introduction component 21 is located inside the outer cylinder 1, Part of the lint collecting assembly 22 is located inside the outer drum 1, and part of it is located outside the outer drum 1. The exhaust portion 221b is formed on the portion of the lint collecting assembly 22 located outside the outer drum 1, and the air driving assembly 23 is also located outside the outer drum 1. In the above three possible situations, the exhaust portion 221b of the lint collecting assembly 22 can be configured to be connected to the outer drum 1 so that air can flow back into the outer drum 1 from the exhaust portion 221b. Of course, during the washing process of the washer-dryer, the water in the outer drum 1 can also flow back into the outer drum 1 after flowing into the lint filtering device, and the water in the outer drum 1 will not be lost.

[0041] On the one hand, the lint collection device 2 of the present invention collects lint by sucking the air in the outer drum 1 into the lint collection device 2 through negative pressure. The lint collection device 2 does not need to completely cover the cross-section of the air duct like a lint filter. On the other hand, the lint collection device 2 is set outside the inner drum. The above two factors avoid a significant increase in the air flow resistance in the air flow path formed between the outer drum 1 and the air duct during the drying process due to the collection of lint, and to a certain extent avoid affecting the drying efficiency, drying effect, and extending the drying time due to resistance.

[0042] Preferably, at least a portion of the air introduction member 21 extends between the circumferential sidewall of the outer drum 1 and the circumference of the inner drum. This arrangement can further reduce the air flow resistance caused by the lint collection device 2, further preventing the resistance from affecting the drying efficiency and effect, and extending the drying time.

[0043] Preferably, if Figure 2As shown, the air introduction component 21 is an air introduction pipe, which is connected to the lint collection component 22 through a first opening 21b formed thereon. The air intake portion 21a includes a first air inlet 21a1, a second air inlet 21a2 and a third air inlet 21a3 formed on the wall of the air introduction pipe. The first air inlet 21a1, the second air inlet 21a2 and the third air inlet 21a3 are arranged in sequence along the gas flow direction in the air introduction pipe and the opening area decreases in sequence. Since the gas in the air inlet pipe flows under the action of negative pressure, the negative pressure in the direction of gas flow in the air inlet pipe gradually increases, that is, the negative pressure formed at the third air inlet 21a3, the second air inlet 21a2, and the first air inlet 21a1 decreases in sequence. By setting the opening areas of the first air inlet 21a1, the second air inlet 21a2, and the third air inlet 21a3 to decrease in sequence along the direction of gas flow in the air inlet pipe, the first air inlet 21a1 and the second air inlet 21a2 can still take in more air per unit time when the negative pressure is relatively small, thereby avoiding affecting the air intake efficiency and thus avoiding affecting the lint collection efficiency. Figure 2 As shown, the number of the first air inlet 21a1, the second air inlet 21a2 and the third air inlet 21a3 are all multiple and all have circular shapes. The circular shape can be easily processed.

[0044] Of course, in addition to the tubular structure of the air introduction tube, the air introduction component 21 can also be a hemispherical structure or other special-shaped structure. In addition, the air intake portion 21a of the air introduction component 21 can be one or more openings. When there are multiple openings of the air intake portion 21a, the shapes of the multiple openings can be the same or different, and the sizes of the multiple openings can also be the same or different. Those skilled in the art can flexibly set the specific structure of the air introduction component 21 and the air intake portion 21a thereon in actual applications, as long as the air intake portion 21a on the air introduction component 21 can allow air to enter the air introduction component 21.

[0045] Preferably, if Figure 2 and 3As shown, the lint collection assembly 22 includes a lint collection barrel 221 and a filter 222. The lint collection barrel 221 is connected to the air introduction member 21 through a second opening 221a formed thereon. The exhaust portion 221b is an exhaust port formed on the lint collection barrel 221, and the filter 222 covers the exhaust port. Further preferably, the second opening 221a is a circular opening, and the inner cavity of the lint collection barrel 221 is a variable diameter cavity, and the diameter of at least a portion of the inner cavity is larger than the diameter of the second opening 221a. When air flows through the inner cavity of the lint collection barrel 221, when the air flows to a portion with a diameter larger than the diameter of the second opening 221a, due to the increased diameter and the lower air pressure, some of the larger lint can fall into the portion with a diameter larger than the diameter of the second opening 221a, thereby allowing the lint collection barrel 221 to collect the lint. The remaining lint that fails to fall into the inner cavity of the lint collection barrel 221 is blocked by the filter 222 and is thus collected.

[0046] Of course, the exhaust portion 221b can also adopt an exhaust pipe, etc.; in addition, the inner cavity of the lint collecting barrel 221 can also be set to a form of equal cross-sectional area, that is, the cross-sectional area size does not change. At this time, a protrusion can be set in the inner cavity of the lint collecting barrel 221 for collecting lint; in addition, the lint collecting assembly 22 can also be set to include only a filter screen 222, and the filter screen 222 cover is provided on the air inlet component 21 for communicating with the lint collecting assembly 22. Those skilled in the art can flexibly set the specific structure of the exhaust portion 221b, the lint collecting barrel 221, and the lint collecting assembly 22 in actual applications, as long as the air in the lint collecting assembly 22 can be discharged through the exhaust portion 221b, the lint collecting barrel 221 and the lint collecting assembly 22 can collect lint.

[0047] Preferably, if Figure 2As shown, the air drive assembly 23 includes an air outlet component 231, a fan 232 and a motor (not shown in the figure). The air outlet component 231 is formed with an air outlet portion 231b and a third opening 231c that are connected to the inner cavity of the air outlet component 231. The air outlet component 231 is connected to the exhaust portion 221b of the lint collection component 22 through the third opening 231c. The fan 232 is arranged in the inner cavity of the air outlet component 231, and the motor is arranged outside the air outlet component 231 and connected to the fan 232. The motor can drive the fan 232 to rotate so that the air in the inner cavity of the air outlet component 231 flows out through the air outlet portion 231b, thereby causing the air to flow on the side of the exhaust portion 221b away from the lint collection component 22, and then the air in the outer cylinder 1 flows through the air inlet component 21, the lint collection component 22 and the air outlet component 231 in sequence, and finally flows out from the air outlet portion 231b. The air drive assembly 23 is configured to include an air outlet component 231 and a fan 232 is arranged in the inner cavity of the air outlet component 231, so that the negative pressure generated by the rotation of the fan 232 can be fully utilized by the lint collection device 2; in addition, the air outlet portion 231b allows the air in the air outlet component 231 to flow out, avoiding the air in the air outlet component 231 from being unable to flow out and generating noise.

[0048] Of course, the air outlet portion 231b can be an air outlet pipe ( Figure 2 and 4 The specific structure of the air outlet portion 231b can be flexibly set by those skilled in the art in practical applications, as long as the air in the inner cavity of the air outlet member 231 can flow out of the air outlet portion 231b. In addition to the above, the air drive assembly 23 can also be configured to include a flat plate, a connecting rod and a cylinder, the flat plate is fixedly connected to one end of the connecting rod, the middle part of the connecting rod is hinged to the box body, and the other end of the connecting rod is fixedly hinged to the piston rod of the cylinder. When the piston rod moves along the cylinder barrel of the cylinder, it can drive the connecting rod to rotate, thereby driving the flat plate to reciprocate, so that the air drive assembly 23 can drive the air flow of the exhaust portion 221b away from the lint collection assembly 22. The specific structure of the air drive assembly 23 can be flexibly set by those skilled in the art in practical applications, as long as the air drive assembly 23 can drive the air flow of the exhaust portion 221b away from the lint collection assembly 22, so that the air in the outer cylinder 1 flows through the air introduction member 21 and the lint collection assembly 22 in sequence to achieve lint collection.

[0049] Preferably, if Figure 2 and 4As shown, there are two air outlet portions 231b, which are arranged opposite each other and are both connected to the two through-ports 1b on the outer drum 1. This arrangement, i.e., the two air outlet portions 231b, allows for a greater amount of air to be discharged per unit time, thereby increasing the amount of air flowing through the lint filter device per unit time, thereby improving lint collection efficiency. Furthermore, the two air outlet portions 231b are arranged opposite each other, further facilitating the outflow of air from the inner cavity of the air outlet member 231. Furthermore, both air outlet portions are connected to the outer drum 1, allowing air to flow back into the outer drum 1 after passing through the lint filter device. Furthermore, during the washing process of the washer-dryer, water in the outer drum 1 can also flow back into the outer drum 1 after flowing into the lint filter device, preventing water loss in the outer drum 1. Further preferably, the fan 232 is a centrifugal fan (the air inlet direction of the centrifugal fan is axial and the air outlet direction is circumferential), and the air outlet portion 231b is located in the circumferential direction of the centrifugal fan, that is, in the air outlet direction of the centrifugal fan. This arrangement allows the air in the inner cavity of the air outlet component 231 to flow out more smoothly.

[0050] Preferably, if Figure 2 and 4 As shown, the fan 232 is a centrifugal fan, and a fourth opening 231d is further formed on the air outlet member 231. The fan 232 is arranged near the fourth opening 231d. The third opening 231c and the fourth opening 231d are arranged opposite to each other along the axial direction of the centrifugal fan and are located in the middle of the air outlet member 231. The inner cavity 231a of the air outlet member 231 gradually narrows from the middle along the first direction D1 and the second direction D2, so that the air outlet member 231 forms two narrowing ends. The two air outlet parts 231b are respectively arranged on the two narrowing ends, wherein the first direction D1 is opposite to the second direction D2, and the first direction D1 and the second direction D2 are both perpendicular to the axial direction of the centrifugal fan. Since the centrifugal fan has an axial air inlet direction and a circumferential air outlet direction, this arrangement facilitates air intake and air outlet when the fan 232 is working, thereby reducing resistance during the air intake and air outlet process, and facilitating air flow through the air outlet component 231. In addition, the inner cavity 231a of the air outlet component 231 gradually shrinks from the middle along the first direction D1 and the second direction D2, respectively, so that the air outlet component 231 forms two shrinking ends, and the two air outlet parts 231b are respectively arranged on the two shrinking ends, so that the air entering from the third opening 231c encounters less resistance in the process of flowing out of the air outlet component 231 under the action of the centrifugal fan, and is gradually guided to the air outlet part 231b.

[0051] Of course, the inner cavity 231a of the air outlet component 231 can also be set to a rectangular parallelepiped or cylindrical shape, and the outer contour of the air outlet component 231 can be set at will by those skilled in the art. Those skilled in the art can flexibly set the specific structure of the air outlet component 231 in actual applications, as long as the air in the air outlet component 231 can flow out to play the role of outlet air.

[0052] Preferably, if Figure 2 As shown, the air driving assembly 23 further includes a sealing member 234 , which covers the fourth opening 231 d and is capable of sealing the fourth opening 231 d . When the fan 232 is located in the inner cavity 231a of the air outlet component 231 and the motor is located outside the air outlet component 231, the output shaft of the motor or one of the shafts of the fan 232 will pass through the sealing component 234. The sealing component 234 can be made of rubber, a rubber plate, a rubber block, etc., so as to ensure that during the washing process, water will neither enter the motor from the edge of the fourth opening 231d nor enter the motor from the hole on the sealing component 234 for passing the output shaft of the motor or the shaft of the fan 232. In addition, the sealing component 234 can also use a plate of metal or other materials as the main body, and a sealing felt ring is provided at the hole for passing the output shaft of the motor or the shaft of the fan 232 to achieve dynamic sealing, thereby preventing water from entering the motor from the hole during the washing process. A sealing ring is arranged around the main body and is tightly fitted with the edge of the fourth opening 231d to prevent water from entering the motor from the edge of the fourth opening 231d during the washing process. Those skilled in the art can flexibly set the specific structure of the sealing component 234 in actual application, as long as the sealing component 234 can prevent water from entering the motor. The provision of the sealing member 234 prevents water from entering the location of the motor during the washing process, thereby preventing the motor from being damaged or leaking electricity due to water ingress.

[0053] Preferably, the air introduction member 21 is detachably connected to the outer cylinder 1 and the lint collecting assembly 22 , respectively, and the lint collecting assembly 22 and the air outlet member 231 are integrally provided. Such a setting, on the one hand, enables the air introduction component 21 to be removed from the outer cylinder 1, making it convenient for the user to clean and replace the air introduction component 21; on the other hand, it enables the lint collection component 22 to be removed from the air introduction component 21, so as to clean the lint in the lint collection component 22. That is to say, when it is necessary to clean the lint in the lint collection component 22, there is no need to disassemble the air introduction component 21, which is very convenient; finally, the lint collection component 22 and the air outlet component 231 are arranged as one body, so that each time the lint collection component 22 is cleaned, the lint collection component 22 and the air outlet component 231 can be removed together, making it convenient for the user to observe whether there is any lint that has not been blocked by the filter 222 and has entered the air outlet component 231, so that the user can clean the air outlet component 231 in time while cleaning the lint collection component 22, avoiding the long-term accumulation of lint in the air outlet component 231, thereby avoiding the entanglement of lint with the fan 232 and damaging the fan 232.

[0054] Specifically, the air introduction component 21 and the outer cylinder 1 can be detachably connected by means of snap connection, screw connection, magnetic attraction, etc. Similarly, the air introduction component 21 and the lint collection assembly 22 can also be detachably connected by the above-mentioned means. The lint collection assembly 22 and the air outlet component 231 can be integrated by means of welding, integral casting, cladding process (the cladding process will be described in detail later), etc. For example, when the lint collection assembly 22 includes a lint collection barrel 221 and a filter screen 222, the lint collection barrel 221, the filter screen 222 and the air outlet component 231 are integrated. The lint collection barrel 221 and the filter screen 222 can be integrated by welding, integral casting, cladding process or other possible methods. The filter screen 222 and the air outlet component 231 can also be integrated by welding, integral casting, cladding process or other possible methods. It should be noted that the purpose of the aforementioned cladding processes is to deposit an alloy onto the surface of an aircraft material. Pre-coating-laser cladding and pneumatic injection are two common cladding processes. In the pre-coating-laser cladding method, the cladding alloy is first deposited on the cladding material surface through methods such as bonding, spraying, electroplating, or pre-positioning wire or sheet material, and then the cladding is melted using a laser beam. In the pneumatic injection method, while the laser beam irradiates the surface of the base material to generate a molten pool, the coating powder is sprayed directly into the laser molten pool using an inert gas to achieve cladding.

[0055] In addition to the above-described arrangements, the air intake member 21 and the outer cylinder 1 may be integrally formed. Furthermore, the air intake member 21 and the lint collection assembly 22 may be integrally formed, and the lint collection assembly 22 and the air outlet member 231 may be detachably connected. Those skilled in the art may flexibly configure the connection between the various components to be detachable or integral as needed, which does not constitute a limitation of the present invention.

[0056] The technical solution of the present invention has been described in detail above, with reference to the case where the clothing processing device is a washer-dryer. In the case where the clothing processing device is a clothes dryer, the clothes dryer also adopts a dual-drum structure, that is, it includes an outer drum and an inner drum rotatably arranged inside the outer drum. When the exhaust portion 221b of the lint collection assembly 22 is located outside the outer drum 1, the exhaust portion 221b can be configured to be directly connected to the housing, that is, the air in the lint collection assembly 22 is directly discharged into the housing through the exhaust portion 221b. When the air drive assembly 23 includes an air outlet component 231, the air outlet component 231 can also be configured to be directly connected to the housing.

[0057] Thus far, the technical solutions of the present invention have 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 scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
