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

[0003] Existing washer-dryer combos mainly include two types: the first is the heat pump type and the second is the condenser type. Both types of washer-dryer combos have an outer drum.

[0004] However, the drying systems of the two types of washer-dryer combos are arranged differently, and the location of the connection structure on the outer drum for connecting to the air duct of the drying system is also different. Specifically, the connection structure for connecting to the air duct on the outer drum of the heat pump washer-dryer combo is located at the upper part of the outer drum, while the connection structure for connecting to the air duct on the outer drum of the condenser washer-dryer combo is located at the lower part of the outer drum. This results in the existing outer drum being only suitable for one type of washer-dryer combo.

[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 the existing outer drum can only be used in one type of washer-dryer combo.

[0014] In the preferred embodiment of the above-mentioned clothing processing equipment, the drying system further includes a lint collection device installed in the drying air duct. The lint collection device includes a housing and a filter screen and a scraping assembly installed on the housing. The housing has an air inlet at a first end along a first direction, and an air outlet between the first end and a second end of the housing. The filter screen is installed at the air outlet. The scraping assembly is located inside the housing and close to the second end of the housing. The scraping assembly can move along the first direction toward the first end of the housing, thereby pushing the lint inside the housing toward the air inlet.

[0015] In the preferred embodiment of the above-mentioned garment processing equipment, the scraping assembly includes a scraping member and a handle. The scraping member is located inside the housing and near the second end of the housing. A first member is provided on the scraping member. The handle is located outside the housing and a second member is provided on the handle. At least one of the first member and the second member has magnetic force so that the first member and the second member attract each other, thereby enabling the handle to drive the scraping member to move along the first direction toward the first end of the housing, thereby causing the scraping member to push the lint inside the housing toward the air inlet.

[0016] In a preferred embodiment of the above-mentioned garment processing equipment, the lint collecting device further includes a button, an elastic reset member, and an elastic drive member mounted on the housing. The button has a first locking structure, and the scraping member has a second locking structure. The first locking structure and the second locking structure cooperate to lock the scraping member in an initial position. The elastic reset member is mounted between the housing and the button. When the button is pressed, the elastic reset member is compressed or stretched. When the button is released from pressure, the elastic reset member resets the button. The elastic drive member is mounted between the housing and the scraping member. The elastic drive member extends along the first direction. When the scraping member is in the initial position, the elastic drive member is compressed or stretched. When the first locking structure and the second locking structure separate, the elastic drive member can push or pull the scraping member to move along the first direction toward the first end of the housing. Alternatively, the housing has a first guide structure, and the handle has a second guide structure. The first guide structure and the second guide structure cooperate to allow the handle to move only along the first direction. Alternatively, both the first and second members are magnets.

[0017] In the preferred embodiment of the above-mentioned garment processing equipment, the garment processing equipment further includes a drying system. The drying system includes a second air outlet duct, a condensing air duct, a heating air duct, a second fan, a second return air duct, and a heating component disposed within the heating air duct.

The air outlet port is connected to the air intake port of the second fan. The exhaust port of the second fan is connected to one end of the heating air duct, and the other end of the heating air duct is connected to the return air port of the outer cylinder through the second return air duct.

[0018] With the above technical solution adopted, the outer cylinder of this utility model is provided with a first connecting structure and a second connecting structure that can be connected to the air duct of the drying system at the upper and lower parts of the outer cylinder, respectively. In addition, the outer cylinder can also be provided with an air outlet at the first connecting structure or the second connecting structure, so that the outer cylinder of this utility model can be used in both heat pump type washer-dryer and condenser type washer-dryer.

[0019] Furthermore, by setting the first connecting structure as a first cylindrical connecting structure, this utility model facilitates connection with the air duct of the drying system.

[0020] Furthermore, by providing reinforcing ribs on the outer wall of the first cylindrical connecting structure, this utility model can improve the structural strength of the first cylindrical connecting structure, which is beneficial to improving the connection stability between the first cylindrical connecting structure and the air duct.

[0021] Furthermore, the lint collection device of this utility model has a scraping component inside the housing. When it is necessary to clean the lint inside the housing, the scraping component can push the lint inside the housing toward the air inlet of the housing, which facilitates the cleaning of lint and improves the cleaning efficiency and user experience. In addition, the scraping component can also scrape off the lint on the filter screen. Moreover, by setting a first component and a second component on the scraping component and the handle respectively, the attraction between the first component and the second component can drive the scraping component to move, without the handle directly contacting the scraping component, which can effectively avoid air leakage and lint leakage.

[0022] Furthermore, this invention, by setting a button, can lock the scraping component in its initial position to prevent it from moving automatically. By setting an elastic reset component between the outer shell and the button, the button can be automatically reset, and the first locking structure on the button and the second locking structure on the scraping component can be prevented from automatically separating. By setting an elastic drive component between the scraping component and the outer shell, the scraping component can be automatically driven to move after the button is pressed, thus improving the user experience.

[0023] Furthermore, this utility model guides the handle by setting a first guide structure and a second guide structure, which facilitates the operation of the handle to move with the scraping component and prevents the handle from deviating. Attached Figure Description

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.

[0038] 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.

[0039] 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.

[0040] Specifically, such as Figure 1 As shown, this utility model provides an outer cylinder 2. The upper part of the outer cylinder 2 is provided with a first connecting structure 21 extending outward, and the lower part of the outer cylinder 2 is provided with a second connecting structure 22 extending outward. Both the first connecting structure 21 and the second connecting structure 22 can be used to connect with the air duct of the drying system. Furthermore, the outer cylinder 2 can have an air outlet at the first connecting structure 21 or the second connecting structure 22.

[0041] The outer cylinder 2 of this utility model has a first connecting structure 21 and a second connecting structure 22 respectively provided in the upper and lower parts of the outer cylinder 2, which can be connected to the air duct of the drying system.

When the outer drum 2 is used in a condenser washer-dryer, the sealing component at the second connecting structure 22 is removed, and an air outlet is set at the second connecting structure 22. When the outer drum 2 is used in a washing machine, it is not necessary to remove the sealing components at the first connecting structure 21 and the second connecting structure 22, 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.

[0046] Furthermore, it should be noted that this utility model does not limit the specific structural form of the first connecting structure 21 and the second connecting structure 22. For example, they can be set as a cylindrical connecting structure, a plug-in connecting structure, or a snap-fit ​​connecting structure, etc.

[0047] Furthermore, it should be noted that the present invention does not limit the specific location of the first connecting structure 21 and the second connecting structure 22. For example, the first connecting structure 21 can be set on the top or rear wall of the outer cylinder 2, and the second connecting structure 22 can be set on the bottom or rear wall of the outer cylinder 2.

[0048] Preferably, such as Figure 1 As shown, the first connecting structure 21 is configured as a first cylindrical connecting structure.

[0049] By setting the first connecting structure 21 as a first cylindrical connecting structure, it is easy to connect with the air duct of the drying system.

[0050] Preferably, such as Figure 1 As shown, the outer wall of the first cylindrical connecting structure is provided with reinforcing ribs 211.

[0051] By setting reinforcing ribs 211 on the outer wall of the first cylindrical connecting structure, the structural strength of the first cylindrical connecting structure can be improved, which is beneficial to improving the connection stability between the first cylindrical connecting structure and the air duct.

[0052] Preferably, such as Figure 1 As shown, the first connecting structure 21 is disposed on the top wall of the outer cylinder 2 and near the rear end of the outer cylinder 2.

[0053] For example, the first cylindrical connecting structure is disposed on the top wall of the outer cylinder 2, and the first cylindrical connecting structure is close to the rear end of the outer cylinder 2.

[0054] It should be noted that those skilled in the art can position the first connecting structure 21 on the axis of the outer cylinder 2, or it can be positioned to the left or right of the axis. Figure 1 The first connecting structure 21 shown is located to the right of the axis of the outer cylinder 2.

[0055] Preferably, such as Figure 1 As shown, the second connecting structure 22 is configured as a second cylindrical connecting structure.

[0056] By setting the second connecting structure 22 as a second cylindrical connecting structure, it is easy to connect to the air duct of the drying system.

Figure 1 The second connecting structure 22 shown is located to the left of the axis of the outer cylinder 2.

[0060] The technical solution of this utility model will be described in detail below with reference to two different embodiments of the washer-dryer combo.

[0061] Example 1

[0062] The following is combined with Figures 2 to 9 The first embodiment of the washer-dryer of this utility model will be introduced. The washer-dryer of this embodiment is a heat pump type washer-dryer.

[0065] Preferably, such as Figures 2 to 4 As shown, the drying system of this utility model includes a drying device, which includes a drying air duct 31, a first fan 32, a first air outlet duct 36, a first air return duct 37, and a heat pump module.

[0066] The drying air duct 31 is located above the outer cylinder 2. The bottom end of the first air outlet duct 36 is fixedly connected to the first connecting structure 21, and the top end of the first air outlet duct 36 is fixedly connected to the drying air duct 31. The outer cylinder 2 is provided with an air outlet at the first connecting structure 21. The air outlet is connected to the air inlet of the drying air duct 31 through the first air outlet duct 36. The air outlet of the drying air duct 31 is connected to the air intake of the first fan 32. The exhaust port of the first fan 32 is connected to the return air port of the outer cylinder 2 through the first return air duct 37. The evaporator 33 and the condenser 34 of the heat pump module are installed in the drying air duct 31, and the evaporator 33 is located upstream of the condenser 34.

[0067] It should be noted that the heat pump module also includes a compressor 35, a refrigerant pipe 38 for 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 air duct 31.

[0068] For example, the first connecting structure 21 is a first cylindrical connecting structure. The first cylindrical connecting structure is inserted into the first air outlet duct 36 from the bottom end of the first air outlet duct 36. A clamp is fitted on the first air outlet duct 36 to fix the first air outlet duct 36 to the first cylindrical connecting structure.

The drying air duct 31 is provided with an insertion interface 3112, and the lint collection device 4 is inserted into the drying air duct 31 through the insertion interface 3112.

[0074] When it is necessary to clean the lint in the lint collection device 4, the lint collection device 4 can be removed from the drying air duct 31. A pressure sensor can be installed upstream and downstream of the lint collection device 4. The pressure difference between the two sensors determines whether the lint collection device 4 needs cleaning. When cleaning is required, a prompt message can be sent to the user to remind them to clean the lint collection device 4.

[0075] 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.

[0076] Preferably, such as Figure 2 As shown, the drying air duct 31 is provided with an interface 3112 on the side facing the front panel of the housing 1. The front panel is provided with a disassembly port opposite to the interface 3112, and the lint collection device 4 can be pulled out from the disassembly port.

[0077] When it is necessary to clean the lint collection device 4, the user can pull out the lint collection device 4 from the disassembly port on the front panel of the housing 1 for easy operation. After cleaning the lint collection device 4, the user can then insert the lint collection device 4 back in through the disassembly port.

[0078] Preferably, such as Figures 2 to 4 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 collection 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.

[0079] 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 the first air outlet duct 36. An insertion interface 3112 is provided at the front end of the first air duct 311. The lint collection device 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. The first fan 32 is located at the upper right of the outer cylinder 2. The air inlet of the first fan 32 is connected to the air outlet port 3121 on the second air duct 312.

[0080] 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 first 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.

[0081] 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.

[0082] Preferably, such as Figure 5 and Figure 6 As shown, the lint collection device 4 of this utility model includes a housing 41 and a filter screen installed on the housing 41. The housing 41 has an air inlet 411 at its first end along a first direction, and an air outlet 412 between the first end and the second end of the housing 41. The filter screen is installed at the air outlet 412.

[0083] For example, the outer shell 41 is a cuboid structure, with the first 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. An air outlet 412 is located on the side plate between the first end and the second end. A 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 filter screen at the air outlet 412, the lint carried by the airflow is intercepted by the filter screen and remains inside the outer shell 41.

[0084] Preferably, such as Figures 5 to 9 As shown, the wire scraping collection device 4 of this utility model also includes a scraping component, which is located at the second end of the housing 41. The scraping component can move along the first direction toward the first end of the housing 41 to push the wire scraping inside the housing 41 toward the air inlet 411.

[0085] By providing a scraping component inside the housing 41, when it is necessary to clean the lint inside the housing 41, the scraping component can push the lint inside the housing 41 toward the air inlet 411 of the housing 41, which facilitates the cleaning of lint, improves the cleaning effect of lint, and enhances the user experience. In addition, as the scraping component moves toward the first end of the housing 41, it can also scrape off the lint on the filter screen.

[0086] Preferably, such as Figures 5 to 9 As shown, the scraping assembly of this utility model includes a scraping component 42 and a handle 43. The scraping component 42 is located inside the outer casing 41, and a first component 44 is provided on the scraping component 42 (see details). Figure 7The handle 43 is located outside the housing 41, and a second component 45 is provided on the handle 43 (see details). Figure 7 At least one of the first component 44 and the second component 45 has a magnetic force, so that the first component 44 and the second component 45 attract each other, thereby enabling the handle 43 to drive the scraping component 42 to move along the first direction toward the first end of the housing 41, thereby causing the scraping component 42 to push the wire debris inside the housing 41 toward the air inlet 411.

[0087] In other words, the handle 43 does not contact the scraping member 42. This eliminates the need to make holes in the housing 41 to connect the handle 43 and the scraping member 42. This design avoids air leakage, which helps ensure drying efficiency and prevents lint from leaking out.

[0088] For example, the edge of the scraping member 42 is attached to the inner wall of the housing 41, and the handle 43 is located on the top surface of the housing 41. As the handle 43 moves with the scraping member 42, the scraping member 42 pushes the wire debris inside the housing 41 toward the air inlet of the housing 41. By making the edge of the scraping member 42 attached to the inner wall of the housing 41, it is beneficial to clean the wire debris inside the housing 41.

[0089] It should be noted that this utility model does not limit the specific structural form of the scraping component 42. For example, the scraping component 42 can be set as a plate structure, a block structure, or a frame structure, etc.

[0090] Furthermore, it should be noted that, in practical applications, those skilled in the art can set one of the first component 44 and the second component 45 as a magnet or electromagnet, and set the other of the first component 44 and the second component 45 as a metal component (such as an iron block) capable of generating an attractive force with a magnet. Alternatively, both the first component 44 and the second component 45 can be set as magnets or electromagnets, etc. 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.

[0091] Preferably, such as Figure 7 As shown, both the first component 44 and the second component 45 are magnets.

[0092] By setting both the first component 44 and the second component 45 as magnets, the attraction between the first component 44 and the second component 45 is stronger, which helps the handle 43 to move smoothly with the scraping component 42.

[0093] Preferably, such as Figure 7 and Figure 8As shown, the scraping component 42 of this utility model is provided with a first receiving and limiting groove 423 on the side facing the handle 43, and the first component 44 is located in the first receiving and limiting groove 423. The handle 43 is provided with a second receiving and limiting groove on the side facing the scraping component 42, and the second component 45 is located in the second receiving and limiting groove.

[0094] By installing the first component 44 and the second component 45 in the first receiving limiting groove 423 and the second receiving limiting groove respectively, it is possible to prevent the first component 44 from moving relative to the scraping component 42 and to prevent the second component 45 from moving relative to the handle 43, which is more conducive to the smooth movement of the handle 43 with the scraping component 42.

[0095] For example, the handle 43 is located above the scraping member 42, the first receiving and limiting groove 423 is provided on the top of the scraping member 42, the first receiving and limiting groove 423 is a rectangular groove, and a rectangular magnet block (i.e., the first member 44) is installed in the first receiving and limiting groove 423. The second receiving and limiting groove is provided on the lower surface of the handle 43, the second receiving and limiting groove is also a rectangular groove, and a rectangular magnet block (i.e., the second member 45) is also installed in the second receiving and limiting groove.

[0096] Preferably, such as Figure 5 and Figure 9 As shown, the outer casing 41 is provided with a first guide structure 414, and the handle 43 is provided with a second guide structure 431. The first guide structure 414 and the second guide structure 431 cooperate to enable the handle 43 to reciprocate only in the first direction.

[0097] The handle 43 is guided and limited by the first guide structure 414 and the second guide structure 431, which facilitates the operation of the handle 43.

[0098] For example, the first guide structure 414 is disposed on the top of the housing 41. With the cooperation of the first guide structure 414 and the second guide structure 431, the handle 43 can only move along the length direction of the housing 41, and cannot move along the width direction of the housing 41 or along the height direction of the housing 41.

[0099] It should be noted that this utility model does not limit the specific structural form of the first guide structure 414 and the second guide structure 431. For example, the first guide structure 414 and the second guide structure 431 can be configured as a structure in which the guide groove and the guide rib cooperate, or as a structure in which the guide rod and the guide hole cooperate, or as a structure in which the guide groove and the guide post cooperate, etc.

[0100] Preferably, such as Figure 5 and Figure 9As shown, a strip-shaped groove 415 is provided on the top of the outer shell 41. The strip-shaped groove 415 extends along the first direction. The first guide structure 414 is a guide groove formed on the side wall of the strip-shaped groove 415. The guide groove extends along the first direction. The second guide structure 431 is a guide rib adapted to the guide groove. The guide rib is inserted into the guide groove.

[0101] For example, a strip groove 415 is formed on the upper surface of the housing 41 and extends along the length of the housing 41. A guide groove is formed on each of the two side walls of the strip groove 415. A guide rib is provided on each side of the handle 43, and the two guide ribs are respectively inserted into the corresponding guide grooves.

[0102] Preferably, such as Figures 5 to 7 As shown, the scraping component of this utility model also includes a button 46 installed on the housing 41. The button 46 is provided with a first locking structure 461, and the scraping component 42 is provided with a second locking structure 422. The first locking structure 461 and the second locking structure 422 cooperate to lock the scraping component 42 in the initial position.

[0103] By setting button 46, it is possible to prevent the scraping component 42 from moving automatically in the first direction.

[0104] For example, a mounting hole is provided on the top of the housing 41, and a mounting cavity 416 is provided inside the housing 41 (see details). Figure 7 The mounting cavity 416 is located directly below the mounting hole. The button 46 is inserted vertically into the mounting cavity 416 through the mounting hole. The top surface of the button 46 is basically flush with the top surface of the outer shell 41. When it is necessary to scrape the wire debris inside the outer shell 41 by scraping the scraping member 42, press the button 46 down to separate the first locking structure 461 on the button 46 from the second locking structure 422 on the scraping member 42. Then, the scraping member 42 can be moved along the first direction by the handle 43.

[0105] It should be noted that in order to prevent air leakage at the mounting hole, a sealing structure needs to be set. For example, a rubber sleeve can be installed on the top of button 46, and the rubber sleeve can be sealed and fitted to the inner wall of the mounting hole, etc.

[0106] Furthermore, it should be noted that this utility model does not limit the structural form of the first locking structure 461 and the second locking structure 422. For example, it can be configured as a structure in which the lock hook and the lock hole cooperate, or as a structure in which two lock hooks cooperate, etc. Such adjustments and changes to the specific structural forms of the first locking structure 461 and the second locking structure 422 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.

[0107] Preferably, such as Figure 7As shown, the first locking structure 461 is a first locking hook, and the second locking structure 422 is a second locking hook that cooperates with the first locking hook.

[0108] For example, the button 46 is provided with two first hooks, which are distributed vertically at intervals and both facing upwards. The scraping member 42 is provided with two second hooks, which are distributed vertically at intervals and both facing downwards. The two first hooks hook the corresponding second hooks respectively.

[0109] Preferably, such as Figure 7 As shown, the scraping assembly of this utility model also includes an elastic reset member 47 installed between the housing 41 and the button 46. After the button 46 is pressed, the elastic reset member 47 is compressed or stretched, and the elastic reset member 47 resets the button 46 after the button 46 is released from pressure.

[0110] For example, the elastic reset member 47 is configured as a vertical spring. A limiting post 417 is provided on the bottom wall of the mounting cavity 416 of the housing 41. The bottom end of the button 46 is provided with a slot 462, which extends along the length of the button 46. The elastic reset member 47 is inserted into the slot 462. The top end of the elastic reset member 47 abuts against the top wall of the slot 462, and the bottom end of the elastic reset member 47 is sleeved on the limiting post 417 and abuts against the bottom wall of the mounting cavity 416. When the user presses the button 46 down, the button 46 moves vertically downward, and the elastic reset member 47 is compressed. When the user stops pressing the button 46, the elastic reset member 47 pushes the button 46 upward, so that the button 46 is reset.

[0111] It should be noted that the elastic reset component 47 is not limited to the spring mentioned above. For example, it can also be set as a rubber column or an elastic rope. If it is an elastic rope, the top end of the elastic rope can be fixedly connected to the inner wall of the outer casing 41, and the bottom end of the elastic rope can be fixedly connected to the button 46. When the button 46 is pressed down, the elastic rope is stretched. After the button 46 is released, the elastic rope contracts, thereby resetting the button 46. Such adjustments and changes to the specific structural form of the elastic reset component 47 do not deviate from the principle and scope of this utility model and should be limited to the protection scope of this utility model.

[0112] Preferably, such as Figure 6 and Figure 8 As shown, the scraping component 42 of this utility model is provided with a guide cylinder 421, and the outer shell 41 is provided with a guide rod 413 adapted to the guide cylinder 421. The guide rod 413 extends along the first direction, and the guide cylinder 421 is sleeved on the guide rod 413. The guide cylinder 421 and the guide rod 413 are guided and cooperated to guide the scraping component 42 during its movement along the first direction.

[0113] For example, three guide rods 413 are provided on the outer shell 41, two of which are located at the top, near the top of the outer shell 41 and spaced apart along the width direction of the outer shell 41, and the remaining guide rod 413 is located at the bottom, near the inner bottom wall of the outer shell 41 and in the middle of the inner bottom wall. That is, the three guide rods 413 are distributed in an inverted triangular shape. The number of guide cylinders 421 is also three, and the distribution is the same as that of the guide rods 413, that is, they are also distributed in an inverted triangular shape.

[0114] It should be noted that, in practical applications, those skilled in the art can also arrange the three guide cylinders 421 and the three guide rods 413 in a triangular pattern. Furthermore, the number of guide cylinders 421 and the number of guide rods 413 are not limited to the three mentioned above. For example, they can also be set to one, two, or four, 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.

[0115] During the movement of the scraping component 42 along the first direction, the guide cylinder moves along the length of the guide rod to prevent the scraping component 42 from shifting.

[0116] Preferably, such as Figure 6 As shown, the scraping assembly of this utility model also includes an elastic driving member 48 disposed between the scraping member 42 and the housing 41. The elastic driving member 48 extends along a first direction. When the scraping member 42 is in the initial position, the elastic driving member 48 is compressed or stretched. When the first locking structure 461 on the button 46 is separated from the second locking structure 422 on the scraping member 42, the elastic driving member 48 can push or pull the scraping member 42 to move along the first direction toward the first end of the housing 41.

[0117] In other words, when button 46 is pressed, the scraping member 42 can also move along the first direction under the action of the elastic drive member 48.

[0118] For example, the elastic drive member 48 is configured as a spring, which is sleeved on the guide rod 413. The elastic drive member 48 is located between the guide cylinder 421 and the outer shell 41, specifically between the second end of the guide cylinder 421 and the outer shell 41. The two ends of the elastic drive member 48 abut against the guide cylinder 421 and the outer shell 41, respectively. When the scraping member 42 is in the initial position, the elastic drive member 48 is in a compressed state. After the user presses down the button 46, the first locking structure 461 on the button 46 separates from the second locking structure 422 on the scraping member 42, and the elastic drive member 48 pushes the scraping member 42 to move toward the first end of the outer shell 41.

[0119] It should be noted that, in practical applications, those skilled in the art can also place the elastic drive member 48 between the guide cylinder 421 and the first end of the housing 41. In this case, when the scraping member 42 is in the initial position, the elastic drive member 48 is in a stretched state. After the user presses down the button 46, the first locking structure 461 on the button 46 separates from the second locking structure 422 on the scraping member 42, and the elastic drive member 48 pulls the scraping member 42 toward the first end of the housing 41.

[0120] Furthermore, it should be noted that the elastic drive component 48 is not limited to the spring described above. For example, it can also be an elastic component such as a rubber column, a rubber sleeve, or an elastic rope. Of course, this invention preferably uses a spring as the elastic drive component 48.

[0121] Furthermore, it should be noted that when multiple guide rods 413 are provided, it is preferable to sleeve an elastic driving member 48 on each guide rod 413. For example, there are three guide rods 413 and three elastic driving members 48, which are respectively sleeved on the corresponding guide rods 413. Such flexible adjustment and change do not deviate from the principle and scope of this utility model and should be limited to the protection scope of this utility model.

[0126] The second connecting structure 22 on the outer cylinder 2 is located near the bottom of the outer cylinder 2. The condensing air duct 52 is located behind the outer cylinder 2. The left and right ends of the second air outlet duct 51 are fixedly connected to the second connecting structure 22 and the condensing air duct 52, respectively. When the drying mode is executed, the second fan 53 starts running. The humid air in the outer cylinder 2 is discharged through the air outlet and enters the condensing air duct 52 along the second air outlet duct 51. Then it flows upward along the condensing air duct 52. Cooling water is introduced into the condensing air duct 52 to condense and dehumidify the humid air. The dried air enters the heating air duct 54 and is heated by the heating components in the heating air duct 54.
