[0055] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0056] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0057] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0059] Nowadays, most users choose to have a washing machine and a washer-dryer combo, or a washing machine and a dryer. However, when users need to wash and care for clothes separately, especially when washing a small amount of clothes for multiple people, multiple washing machines are required, which is costly. Operating multiple washing machines simultaneously is also difficult and cumbersome, and cannot adequately meet users' washing and care needs.

[0060] To address the need for categorized laundry care, some garment processing equipment is equipped with multiple rollers for processing clothes. However, multi-roller garment processing equipment in this technology has low space utilization, which affects the miniaturization of the equipment.

[0061] To address the above problems, this application provides a garment processing device 100. Please refer to... Figures 1 to 3 The garment processing equipment 100 includes a housing 60, a heat pump system 30, a drive system 40, a first roller 10, and a second roller 20. The heat pump system 30, the drive system 40, the first roller 10, and the second roller 20 are all installed inside the housing 60.

[0062] For ease of explanation, the definitions are as follows: Figure 2 The diagram shows the vertical directions (up / down, left / right, and front / back).

[0063] In this embodiment, the housing 60 constitutes the outer shell 63 of the clothing processing equipment 100, and can provide a mounting base for devices such as the drive system 40, heat pump system 30, first roller 10 and second roller 20, and play a protective role. At the same time, the surface of the housing 60 also constitutes the main appearance surface of the clothing processing equipment 100.

[0064] In some embodiments, a base 61 is formed at the bottom of the housing 60, which is used to support the ground or mounting surface. The first roller 10, the heat pump system 30, the drive system 40, and the second roller 20 are all connected to the base 61. Optionally, the garment processing equipment 100 further includes a vibration damping structure connected to the base 61. At least one second roller 20 is connected to the vibration damping structure to buffer the movement of the second roller 20, thereby improving the operational stability of the second roller 20 and the overall stability of the garment processing equipment 100. Optionally, the vibration damping structure includes vibration damping pads, vibration damping springs, etc. For example, in an embodiment where the vibration damping structure uses vibration damping springs, one end of the vibration damping spring is connected to the base 61, and the other end is connected to the second roller 20, so as to buffer the vibration of the second roller 20.

[0065] In fact, the embodiments of this application do not limit the second roller 20 to be installed on the base 61. The second roller 20 can also be installed on other parts of the box 60 other than the base 61, or it can be directly set on the ground or mounting surface and located inside the box 60.

[0066] The first roller 10 and the second roller 20 are the main structures in the garment processing device 100 used to provide garment processing functions. The first roller 10 defines a first garment processing chamber and a first inlet communicating with the first garment processing chamber. Correspondingly, the second roller 20 defines a second garment processing chamber and a second inlet communicating with the second garment processing chamber. Garments can be put into the first garment processing chamber and the second garment processing chamber through the first inlet and the second inlet, respectively, or can be taken out from the first garment processing chamber and the second garment processing chamber through the first inlet and the second inlet, respectively.

[0067] For situations where clothing needs to be sorted for processing, users can sort the clothing according to the actual situation and put the clothing into the first drum 10 and the second drum 20 for processing, so as to meet the diverse washing and care needs of users.

[0068] like Figure 1 As shown, optionally, the diameter of the second roller 20 is smaller than the diameter of the first roller 10. This allows customers to more clearly categorize items, such as placing large garments in the first roller 10 and small garments in the second roller 20. This is especially beneficial for ensuring hygiene and reducing bacterial infection, particularly when the small garments are underwear. Understandably, the second roller 20, while meeting the user's need for garment sorting, consumes less energy due to its smaller size, thus reducing operating costs.

[0069] In one embodiment, the central axis of the first roller 10 is parallel to the central axis of at least one second roller 20. When there are multiple second rollers 20, one or more of the second rollers 20 may have their central axes parallel to the central axis of the first roller 10; alternatively, all the second rollers 20 may have their central axes parallel to the central axis of the first roller 10, making the garment processing device 100 appear neater and more aesthetically pleasing. With the central axes of the first roller 10 and the second roller 20 being parallel, the orientation of the first and second loading ports can be set to face one side of the garment processing device 100, such as the front. This allows users to load garments only from one side of the garment processing device 100, preventing the garment processing device 100 from occupying more space.

[0070] Furthermore, the central axis of the first roller 10 and the central axis of at least one second roller 20 are both set horizontally, which makes it easier for users to pick up and put down clothes, and also makes the first roller 10 and the second roller 20 process the clothes more comprehensively and thoroughly.

[0071] Combination Figure 2 and Figure 3The drive system 40 is adapted to drive the first roller 10 and the second roller 20 to rotate relative to the base 61, so as to process the clothes in the first and second garment processing chambers. Optionally, the drive system 40 adopts a direct drive or a transmission drive method. For example, in the direct drive method, the drive motor 41 is directly mounted on the bottom of the first roller 10 and the second roller 20, respectively, and the first roller 10 and the second roller 20 are directly connected to the output end of the drive connection, reducing intermediate transmission links, improving transmission efficiency, and reducing noise and vibration; in the transmission drive method, the power of the drive motor 41 is transmitted to the first roller 10 and the second roller 20 through transmission structures such as belts, gears, and chains. This drive method has lower cost and maintenance cost, and can realize multiple drive modes.

[0072] The heat pump system 30 heats the airflow through refrigerant circulation. Optionally, the heat pump system 30 includes a compressor 34, a condenser 33, and an evaporator 32. The compressor 34, condenser 33, and evaporator 32 are all housed within a casing 60 and are connected by refrigerant pipelines. The specific principle is as follows: the compressor 34 draws in low-pressure gaseous refrigerant, compresses it, and discharges it at high pressure. The discharged high-pressure refrigerant enters the condenser 33, is cooled by ambient air, and condenses into a high-pressure liquid (while transferring heat to the surrounding air). The high-pressure liquid refrigerant flows through an expansion valve for throttling and pressure reduction, becoming a low-pressure, low-temperature gas-liquid two-phase mixture before entering the evaporator 32. The liquid refrigerant evaporates and cools in the evaporator 32 (while absorbing heat from the surrounding air). The resulting low-pressure gaseous refrigerant is drawn back into the compressor 34 and pressurized. This cycle repeats continuously to achieve heat exchange and heat the airflow.

[0073] During the drying process: the high-temperature dry air heated by the condenser 33 flows over the surface of the wet clothes, exchanges heat and moisture with the clothes, absorbs the moisture from the clothes, and becomes high-temperature, high-humidity gas. The high-temperature, high-humidity gas is then cooled by the evaporator 32 into low-temperature, low-humidity gas, which flows back to the condenser 33. This cycle continues, achieving continuous and efficient drying of the clothes.

[0074] The heat pump system 30 of this application embodiment is at least used to supply heated airflow to the first drum 10. Please refer to... Figure 2 and Figure 3In some embodiments, the heat pump system 30 further includes a drying tunnel housing 31 and a fan 35. The drying tunnel housing 31 defines a drying tunnel communicating with the internal space of the first roller 10. At least a portion of the structure of the condenser 33 and at least a portion of the structure of the evaporator 32 are disposed within the drying tunnel as heat exchange components and are spaced apart along the airflow direction (front-to-back direction). The fan 35 is also disposed within the drying tunnel to drive airflow within the drying tunnel. Under the action of the fan 35, the airflow circulates between the drying tunnel and the first garment processing chamber. Of course, the drying tunnel may also be defined by the drying tunnel housing 31 and the housing 60 together; this embodiment does not limit this. The drying tunnel housing 31 is made of metal or other high-temperature resistant materials to have sufficient strength and good resistance to high-temperature airflow, thereby improving the service life of the drying tunnel housing 31.

[0075] Combination Figure 2 In this embodiment, the drying tunnel shell 31 extends generally in the front-to-back direction, ensuring smooth airflow and providing sufficient space within the drying tunnel for the condenser 33 and evaporator 32, as well as for heat exchange between the airflow and the condenser 33 and evaporator 32. The compressor 34 is located outside the drying tunnel shell 31, positioned on the left or right side of the drying tunnel shell 31 in the left-to-right direction. The second roller 20 is positioned on the left and / or right side of the drying tunnel shell 31 in the left-to-right direction; that is, the second roller 20 can be positioned only on the left side of the drying tunnel shell 31 or only on the right side of the drying tunnel shell 31. When there is more than one second roller 20, it can be positioned on both the left and right sides of the drying tunnel shell 31. This embodiment ensures smooth airflow within the drying tunnel shell 31, facilitating the drying of clothes, while also making reasonable use of the space on the sides of the drying tunnel shell 31 by positioning the compressor 34 and the second roller 20 on the left or right side of the drying tunnel shell 31, resulting in a more compact internal spatial arrangement of the clothing processing equipment 100.

[0076] In this embodiment, at least one second roller 20 is disposed in front of the compressor 34. For example, in one embodiment, the compressor 34 is disposed on the left side of the drying tunnel shell 31, and a second roller 20 is disposed in front of the compressor 34. In this way, the compressor 34 and the second roller 20 are disposed in front of each other and both are disposed on one side of the drying tunnel shell 31, which makes the arrangement of the various components in the clothing processing equipment 100 more compact, the space utilization rate is higher, and it is beneficial to reduce the overall size of the clothing processing equipment 100.

[0077] In some embodiments, the heat pump system 30 and at least one second roller 20 are both disposed below the first roller 10 to lower the center of gravity and improve stability. When there is more than one second roller 20, such as when the garment processing device 100 has two second rollers 20, at least two second rollers 20 are arranged in the left-right direction to balance the front and rear center of gravity of the garment processing device 100, and to make the structure at the bottom of the garment processing device 100 more compact, making reasonable use of the internal space of the garment processing device 100.

[0078] Optionally, at least two second rollers 20 can be arranged together on the left or right side of the heat pump system 30, or they can be arranged separately on the left and right sides of the heat pump system 30. Figure 3 In the embodiment shown, the drying tunnel shell 31 is centrally located, and the two second rollers 20 are located on the left and right sides of the drying tunnel shell 31, respectively. The structure is more symmetrical and the center of gravity is more central, which makes the structure more compact and the garment processing equipment 100 more stable.

[0079] Combination Figure 2 and Figure 3 The drive system 40 includes a drive motor 41 connected to at least one of the first roller 10 and the second roller 20. The drive motor 41 can drive at least one of the first roller 10 and the second roller 20 to rotate using either direct drive or transmission. In a structure using one drive motor 41, the drive motor 41 can be connected to both the first roller 10 and the second roller 20 via transmission, or the output shaft of the drive motor 41 can be directly connected to one of the first roller 10 and the second roller 20, while being connected via transmission to the other. The transmission connection method has been explained previously and will not be repeated here. In a structure using multiple drive motors 41, each drive motor 41 drives at least one roller, and the multiple drive motors 41 can all be used in a direct drive manner, or all in a transmission manner, or a combination of direct drive and transmission methods can be used to drive both the first roller 10 and the second roller 20.

[0080] For example, the garment handling device 100 has a first roller 10 and two second rollers 20. The drive system 40 includes three drive motors 41. One drive motor 41 drives the first roller 10 to rotate via a transmission, and the other two drive motors 41 drive the two second rollers 20 to rotate via direct drive. Understandably, the second rollers 20 are smaller than the first roller 10, and the drive motors 41 used for driving them can also be smaller. Direct drive is more efficient and produces less noise.

[0081] In this embodiment, the drive motor 41 is positioned on the left or right side of the drying tunnel shell 31 along the left-right direction. This embodiment ensures smooth airflow within the drying tunnel shell 31, facilitating the drying of clothes while making efficient use of the space on the side of the drying tunnel shell 31. By positioning the drive motor 41 and the second roller 20 on the left or right side of the drying tunnel shell 31, the internal spatial structure of the clothing processing equipment 100 is arranged more compactly. At least one second roller 20 is positioned in front of the drive motor 41, thus the drive motor 41 and the second roller 20 are arranged one in front of the other and both are located on one side of the drying tunnel shell 31. This makes the arrangement of the components within the clothing processing equipment 100 more compact, improves space utilization, and helps reduce the overall size of the clothing processing equipment 100.

[0082] Furthermore, the drive motor 41 and the compressor 34 are located on the left and right sides of the drying tunnel shell 31, respectively. In a specific embodiment, the compressor 34 is located on the left side of the drying tunnel shell 31, and one drive motor 41 is located on the right side of the drying tunnel shell 31. In this embodiment, there are two second rollers 20, which are respectively located in front of the compressor 34 and the drive motor 41, thereby making the arrangement of the various components within the garment processing equipment 100 more reasonable and compact. In addition, the placement of the drive motor 41 and the compressor 34 on the left and right sides of the drying tunnel shell 31 enables the center of gravity of the garment processing equipment 100 to be more central, improving the stability of the garment processing equipment 100.

[0083] like Figure 3 As shown, in a specific embodiment, the garment processing device 100 includes two second rollers 30. A rectangular coordinate system is established with the center of the base 11 as the origin, and with the X-axis (right-right direction) and the Y-axis (back-front direction) as the positive direction. The drive system 40 is located in the first quadrant, the compressor 41 is located in the second quadrant, and the two second rollers 30 are located in the third and fourth quadrants, respectively. This allows each component to be arranged around the center of the base 11, further improving the uniformity of weight distribution and stability of the garment processing device 100.

[0084] In this embodiment, the heat pump system 30 can simultaneously or individually supply heated airflow to the first drum 10 and the second drum 20. Combined with... Figure 4In one embodiment, the heat pump system 30 includes at least one duct 361. One end of the duct 361 is connected to the drying tunnel shell 31 downstream of the condenser 33, and the other end is connected to the second drum 20. This allows the dry, high-temperature airflow downstream of the condenser 33 within the drying tunnel shell 31 to flow into the second drum 20 for drying clothes. It is understood that one duct 361 corresponds to one second drum 20 and one drying tunnel. Therefore, this embodiment of the application supplies heated airflow to the second drum 20 through the heat pump system 30, enabling the second drum 20 to also perform clothes drying. This allows users to sort clothes according to their actual needs and place the sorted clothes into the first drum 10 and the second drum 20 for simultaneous drying, avoiding the tediousness of drying in stages, improving the efficiency of clothes processing, and preventing interference between different types of clothes, thus ensuring hygiene. In other embodiments of this application, the drying tunnel shell 31 may be constructed by itself or the drying tunnel shell 31 and the housing 60 may be constructed together to form a channel connecting the drying tunnel and the second garment processing chamber, allowing hot airflow to flow from the drying tunnel into the inner space of the second roller 20. In comparison, the method of connecting with the air duct 361 is simpler and more convenient, which can reduce the structural complexity of the drying tunnel shell 31 and the housing 60, reduce the molding difficulty, and reduce the space occupied by the drying tunnel shell 31, making it easier to arrange the components inside the housing 60.

[0085] Combination Figure 4 The heat pump system 30 also includes a switching structure 362, which includes at least one switching valve and at least one switching motor. The switching valve is located at the connection between the air duct 361 and the drying chamber shell 31, and is used to control the opening and closing of the internal space of the drying chamber shell 31 and the air duct 361. Specifically, the drying chamber shell 31 includes an air inlet shell 311, two evaporator shells 312, and an exhaust shell 313 connected together. The air inlet shell 311 is connected to one end of the first roller 10 and the two evaporator shells 312. The two evaporator shells 312 are connected to the housing 60, and the condenser 33 and the evaporator 32 are disposed inside the two evaporator shells 312. The exhaust shell 313 is connected to the two evaporator shells 312 and the other end of the first roller 10. The switching valve is located at the connection between the air duct 361 and the exhaust shell 313, and is used to control the opening and closing of the internal space of the air duct 361 and the exhaust shell 313. Each switch motor is paired with a switch valve to drive the valve's movement. Controlling the opening and closing of the valves controls the connection between the drying tunnel and the second garment processing chamber. Thus, when the switch valve is closed, the heat pump system 30 can supply heated airflow to the first roller 10 alone; when the switch valve is open, the heat pump system 30 can supply heated airflow to both the first roller 10 and the second roller 20 simultaneously. When there are multiple second rollers 20, there are multiple sets of switch valves and switch motors, with each second roller 20 having a corresponding air duct 361, and each air duct 361 having a corresponding set of switch valves and switch motors. This allows for more precise control of the connection between the drying tunnel and the second rollers 20, reducing energy waste.

[0086] Optionally, the air duct 361 connects to the rear cover of the second drum 20, allowing airflow to flow from back to front within the second drum 20, providing more comprehensive contact with the clothes and ensuring good drying results. Furthermore, the second drum 20 is equipped with a sub-air inlet connected to the air duct 361. The sub-air inlet is flat, reducing its width and facilitating the structural arrangement of the second drum 20, while also ensuring a more uniform distribution of airflow entering the second drum 20. Alternatively, the air duct 361 can be a corrugated pipe, capable of expansion and contraction, facilitating structural arrangement. In addition, corrugated pipes offer advantages such as good heat insulation and light weight, effectively reducing heat loss through the air duct 361.

[0087] like Figure 5 In some other embodiments, the second roller 20 may also use a heat source independent of the heat pump system 30 to provide hot airflow. The garment processing equipment 100 also includes a drying device 50, which is disposed within the housing 60 and located outside the cylinder of at least one second roller 20, for supplying hot airflow to the at least one second roller 20. Thus, this embodiment uses a separate drying device 50 to process the garments. On the one hand, this allows for independent control, facilitating the control of the drying process of the first roller 10 and the second roller 20. On the other hand, it avoids the diversion of hot airflow within the drying tunnel, ensuring that the hot airflow within the drying tunnel is supplied solely to the first roller 10, while simultaneously guaranteeing the drying effect of the garments in both the first roller 10 and the second roller 20.

[0088] In one embodiment, the front side of the housing 60 is provided with an exhaust vent, which communicates with the internal space of at least one second roller 20. The exhaust vent is used to discharge the hot and humid air from the at least one second roller 20. The drying airflow introduced into the second roller 20 becomes a hot and humid drying airflow after exchanging heat with the damp clothes. In this embodiment, the hot and humid drying airflow is discharged to the external environment through the exhaust vent, which can prevent the hot and humid drying airflow from staying in the second roller 20 for a long time, reducing or avoiding the problem of bacterial growth. In addition, directly discharging the hot and humid drying airflow to the external environment is simple and convenient to implement, with high assembly efficiency and low manufacturing cost.

[0089] In another embodiment, combined with Figure 6 At least one of the second rollers 20 is also provided with an exhaust duct 623a. The exhaust end of the exhaust duct 623a is connected to the drying tunnel, and the exhaust duct 623a is used to discharge the hot and humid air from the at least one second roller 20 into the drying tunnel. In this way, the hot and humid drying airflow inside the second roller 20 is discharged into the heat pump system 30, which not only allows the hot and humid drying airflow to be discharged from the second roller 20, ensuring the hygiene inside the second roller 20, but also introduces the high-temperature airflow into the heat pump system 30, realizing the utilization of waste heat of the airflow inside the second roller 20 and improving energy utilization efficiency.

[0090] In this embodiment, the housing 60 includes a base 61, a front support beam 621, a front support member 622, a connecting member 623, and an outer shell 63. The base 61 is used to support the housing on the ground or mounting surface. The outer shell 63 surrounds the base 61 to form a shell and is used to form the outer surface of the housing 60. An exhaust vent may be formed on the outer shell 63. The front support beam 621 and the front support member 622 are both disposed on the front side of the base 61, forming at least a partial support structure on the front side of the housing 60. The connecting member 623 is used to define an exhaust duct 623a.

[0091] Specifically, the front support beam 621 is connected to the front side of the base 61, and a portion of the front support beam 621 is spaced apart from the base 61. For example, the front support beam 621 includes a horizontal arm and two side arms arranged opposite each other in the left-right direction. The two side arms are located on opposite sides of the horizontal arm in the left-right direction and are connected to the horizontal arm. The horizontal arm is spaced apart from the base 61 and is used to support the first roller 10. The second roller 20 is also provided with a sub-air outlet 20a, which is connected to the horizontal arm. The air inlet shell 311 is also connected to the horizontal arm. The sub-air outlet 20a is connected to the internal space of the air inlet shell 311 through the exhaust duct 623a. Figure 3 As shown, one side of the door seal portion of the second roller 20 protrudes to form the sub-air outlet 20a. The second roller 20 is mounted on the base 61, and the sub-air outlet 20a is located on the side of the second roller 20 facing away from the base 61 for easy connection and other operations. A clearance opening is provided on the crossbeam corresponding to the sub-air outlet 20a, allowing the sub-air outlet 20a structure to pass through. This not only makes the structure more compact but also positions the sub-air outlet 20a structure for easy installation and limits the movement of the second roller 20, improving its stability. Similarly, the air inlet housing 311 is located between the cross arm and the base 61, and the crossbeam also has a clearance opening corresponding to the air inlet housing 311 for connecting the air inlet housing 311 to the first roller 10.

[0092] In one embodiment of this application, the first roller 10 is located above at least one second roller 20. A front support member 622 is connected to a front support beam 621 and is used to support the first roller 10. The front support member 622 is connected to the crossbeam and generally covers the front side of the first roller 10, improving stability. Optionally, the front support member 622 is provided with an air outlet channel 622a that communicates with the internal space of the first roller 10. The air outlet channel 622a communicates with the internal space of the air inlet shell 311. A connecting member 623 connects to the front support member 622 so that the exhaust duct 623a communicates with the air outlet channel 622a. That is, while supporting the first roller 10, the front support member 622 also integrates the air outlet channel 622a to communicate with the internal space of the first garment processing chamber and the air inlet shell 311, avoiding the need for an additional air outlet channel 622a structure, making the structure more compact, reducing the number of parts, which is beneficial for reducing the volume and improving the structural reliability of the garment processing equipment 100.

[0093] Furthermore, the connecting member 623 and the front support member 622 are an integral structure. For example, the connecting member 623 and the front support member 622 can be integrally cast. The integral construction of the connecting member 623 and the front support member 622 can reduce the connection steps during installation, improve operational efficiency, and also improve airtightness, reducing air leakage and noise generation. Of course, the connecting member 623 and the front support member 622 can also be connected by bolts or other means after being formed separately, and this embodiment of the application does not limit this.

[0094] In one embodiment, the garment processing device 100 further includes a filter device 90 disposed within the air outlet channel 622a for filtering the airflow passing through the air outlet channel 622a. In one structural form, the air outlet channel 622a includes a main air outlet channel 622a and a sub-air outlet channel 622a, both of which are connected to the internal space of the air inlet housing 311. The exhaust duct 623a is connected to the sub-air outlet channel 622a. Filter devices 90 are respectively disposed within the main air outlet channel 622a and the sub-air outlet channel 622a to filter the airflow discharged from the first roller 10 and the second roller 20, thereby improving the quality of the circulating airflow, reducing odors, and preventing airway blockage. In another structural form, the filter device 90 is entirely located within the air outlet channel 622a, and the filter device 90 itself has a main filter channel and a sub-filter channel that are both connected to the internal space of the air inlet shell 311. The main filter channel is connected to the air outlet channel 622a, and the sub-filter channel is connected to the exhaust duct 623a, so as to filter the airflow discharged from the first roller 10 and the second roller 20 respectively. It can be understood that in an embodiment where there are two second rollers 20, the two second rollers 20 are respectively connected to the drying tunnel through two exhaust ducts 623a, and the filter device 90 has two sub-filter channels corresponding to the two exhaust ducts 623a. Alternatively, the filter device 90 may include at least two filter elements or filter screens, which are respectively disposed at the inlet of the air outlet channel 622a and at the connection point between the exhaust duct 623a and the air outlet channel 622a, so as to filter the airflow discharged from the first roller 10 and the second roller 20 separately, and reduce the obstruction of airflow by the filter device 90.

[0095] Of course, in other embodiments, the housing 60 may also be provided with a separate front support beam 621 or a front support member 622 to support the first roller 10, with the front support beam 621 or the front support member 622 directly supported on the base 61. For example, in an embodiment where the front support beam 621 is provided separately, the air outlet channel 622a can be provided by an additional air duct component, while in an embodiment where the front support member 622 is provided separately, the sub-air outlet interface 20a and the air inlet shell 311 can be directly connected to the support member 622. This application embodiment does not impose any restrictions on this.

[0096] To further improve the structural strength of the housing 60, in some embodiments, the base 61 includes a base plate located at the center of the bottom of the base. At least one of the rear, left, and right sides of the base plate is provided with a folding plate extending vertically. For example, the base 61 includes a left folding plate, a right folding plate, and a rear folding plate connected to the base plate. The outer shell 63 includes a left side plate, a right side plate, a rear back shell, and a front shell. The left side plate can be connected to the outer or inner side of the left folding plate; similarly, the right side plate can be connected to the outer or inner side of the right folding plate, and the back shell plate can be connected to the outer or inner side of the rear folding plate. By providing folding plates, not only can the strength of the base 61 be improved, but the contact area between the base 61 and the outer shell 63 can also be increased, thereby improving the stability of the housing 60.
