Description

Technical Field

[0001] This application relates to the field of clothing processing, and more specifically, to a clothing processing device. Background Technology

[0002] As people's living standards improve, the demand for clothing processing equipment is also constantly growing. Multi-drum clothing processing equipment, by setting up multiple drums, realizes the classification, washing, or drying of clothes, meeting users' needs for clothing classification and processing.

[0003] In multi-drum garment processing equipment, a heat pump system is typically used to dry clothes. This system achieves efficient drying through refrigerant circulation. However, in existing multi-drum garment processing equipment, the heat pump system requires a separate space for installation. This design not only leads to an unnecessary increase in the overall size of the garment processing equipment, but also makes it difficult to achieve a reasonable arrangement of various components within the limited space, thus affecting the overall layout and space utilization efficiency of the equipment. Utility Model Content

[0004] This application provides a garment processing device aimed at improving the space utilization of garment processing equipment.

[0005] This application provides a garment processing device, including:

[0006] First roller;

[0007] At least two second rollers are arranged at intervals in a left-right direction and are located above or below the first roller, wherein the diameter of the second rollers is smaller than the diameter of the first roller; and

[0008] The heat pump system includes at least a drying tunnel shell communicating with the first roller, an evaporator and a condenser both disposed within the drying tunnel shell, and at least a portion of the drying tunnel shell is disposed between at least two second rollers along the left-right direction.

[0009] In some embodiments, the drying tunnel shell includes:

[0010] Two housings are provided to cover the evaporator and the condenser;

[0011] The two housings are located between at least two of the second rollers.

[0012] In some embodiments, the two housings are centered along the left-right direction.

[0013] In some embodiments, the drying tunnel shell further includes:

[0014] An air inlet housing is connected to the front end of the two housings and communicates with the first roller, with at least a portion of the air inlet housing located between at least two of the second rollers.

[0015] In some embodiments, two second rollers are provided, both of which are located below the first roller;

[0016] Wherein, along the vertical direction of the garment processing device, the projections of the two second rollers are at least partially located within the projection of the first roller; and / or, the two second rollers are symmetrically arranged about a plane of symmetry along the left-right direction, and the rotation axis of the first roller is located within the plane of symmetry.

[0017] In some embodiments, the garment processing device further includes a housing, the housing comprising:

[0018] The base, the two shells and the air inlet shell are all disposed on the base and together with the base form a drying cavity, and the evaporator and the condenser are arranged in the drying cavity in the front-to-back direction.

[0019] In some embodiments, the housing further includes:

[0020] A base plate is disposed on the base, and the second roller is disposed on the base plate and / or the base.

[0021] In some embodiments, the base plate has a left folding plate and a right folding plate, the left folding plate and the right folding plate are arranged opposite each other in the left-right direction, and both the left folding plate and the right folding plate are folded and extended toward the first roller;

[0022] The housing also includes a left side plate and a right side plate arranged opposite to each other along the left-right direction. The left side plate is connected to the left folding plate and is located between the left folding plate and a second roller. The right side plate is connected to the right folding plate and is located between the right folding plate and another second roller.

[0023] In some embodiments, it also includes:

[0024] At least two drying devices are connected to at least two of the second drums in a one-to-one correspondence;

[0025] Wherein, along the vertical direction, the projections of the two drying devices are located within the projection of the first drum; and / or, the two drying devices are symmetrically arranged about a plane of symmetry along the horizontal direction, and the rotation axis of the first drum is located within the plane of symmetry.

[0026] In some embodiments, the garment processing apparatus further includes:

[0027] The drive system includes a drive motor for driving the first roller to rotate, the drive motor being located behind one of the second rollers.

[0028] In some embodiments, the heat pump system further includes:

[0029] The compressor is located behind one of the second rollers.

[0030] Based on the garment processing equipment of this application, at least a portion of the drying tunnel shell is disposed between at least two second rollers in the left-right direction, making full use of the gap between the second rollers, thereby improving the utilization rate of the internal space of the garment processing equipment within a limited volume, and making the overall structural layout of the garment processing equipment more compact.

[0031] Because at least a portion of the drying tunnel shell is positioned between at least two second rollers along the left-right direction, the weight distribution and stress on both sides of the garment processing equipment are relatively balanced. This balanced layout helps ensure the overall stability of the equipment during operation, especially during dynamic operations such as roller rotation and hot air circulation. The second rollers on both sides cooperate with the drying tunnel shell to form a relatively symmetrical structure, effectively suppressing vibrations and shaking generated during operation, thus achieving a more stable operating state.

[0032] Furthermore, positioning the drying tunnel shell between at least two second rollers helps lower the center of gravity of the entire garment processing equipment. Because the drying tunnel shell and its internal components, such as the evaporator and condenser, have a certain weight, placing it at a lower position between the second rollers lowers the equipment's center of gravity. Compared to placing the drying tunnel shell at the top or other higher positions of the equipment, this design makes the equipment more stable during operation, reducing the risk of swaying and tipping due to a high center of gravity, and improving the safety and reliability of the equipment.

The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0041] 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.

[0042] As people's living standards improve, their demands in all aspects are also increasing, especially in clothing cleaning. Modern consumers are no longer satisfied with simple washing but are beginning to pursue more meticulous and professional clothing care. For example, when washing clothes, people tend to categorize them meticulously according to type, material, and color to ensure that each garment receives the most suitable cleaning and protection. This categorization includes not only outerwear, underwear, and socks but also clothing of different colors and even clothing of different materials.

[0043] To meet this growing segmentation of demand, an innovative garment processing device 100 has emerged on the market—a garment processing device 100 equipped with multiple drums. This garment processing device 100 is designed to allow users to wash multiple types of clothing simultaneously without worrying about color mixing or material damage. The multi-drum garment processing device 100 not only improves washing efficiency but also provides users with a more personalized and professional laundry solution.

[0044] Please see Figure 1 This application provides a garment processing device 100, which includes a first roller 20 and at least two second rollers 30. The first roller 20 has a first garment processing chamber 21, and the second rollers 30 have a second garment processing chamber 31. The multi-roller garment processing device 100 allows users to process multiple batches of garments simultaneously. On the one hand, it can process more garments, and on the other hand, it allows users to perform more detailed sorting and washing according to the type, material, and color of the garments. For example, outerwear, underwear, socks, and garments of different shades can be washed separately, which can avoid cross-contamination and protect the color and material of the garments from damage.

[0045] In this embodiment, the central axis of the first roller 20 is parallel to the central axis of the second roller 30. This parallel axis design makes more efficient use of space, allowing the first roller 20 and at least two second rollers 30 to be arranged compactly, which is suitable for environments with limited space. Furthermore, the central axes of both the first roller 20 and the second roller 30 are horizontally set. Horizontal setting means that the central axes of the rollers are parallel to the horizontal plane and do not tilt upwards or downwards. By setting them horizontally, the first roller 20 and the second roller 30 can maintain a stable operating state during rotation, reducing vibration and noise caused by tilting, thereby improving the overall performance of the equipment.

[0046] In other embodiments, the central axis of the first roller 20 may not be parallel to the central axis of the second roller 30, or both the central axes of the first roller 20 and the second roller 30 may be set at an angle to the horizontal direction. This application does not impose any limitations on this.

[0047] At least two second rollers 30 are arranged at intervals in the left-right direction and are located above or below the first roller 20. Understandably, the loading ports of both the first roller 20 and the second roller 30 face one side, with the side facing the user being the front side. When the user faces the garment processing device 100, the left and right sides constitute the left-right direction, meaning at least two second rollers 30 are on the same horizontal plane, arranged at a certain interval. The number of second rollers 30 can be two, three, four, or even more; this application does not limit this. The up-down direction refers to the height of the garment processing device 100. Placing at least two second rollers 30 above or below the first roller 20 utilizes vertical space, reducing the footprint of the garment processing device 100, which is particularly advantageous in space-constrained environments (such as home laundry rooms, small laundromats, etc.).

[0048] The diameter of the second roller 30 is smaller than that of the first roller 20. By arranging at least two smaller second rollers 30 above or below the first roller 20, this design can make more efficient use of space and improve the structural compactness of the garment processing equipment 100, making it especially suitable for home environments with limited space.

[0049] Please continue reading. Figure 1 The garment processing equipment 100 also includes a heat pump system 40, which is a heat energy conversion device capable of absorbing heat from a low-temperature environment and releasing it to a high-temperature environment. In the garment processing equipment 100, the heat pump system 40 is mainly used for drying clothes, reducing energy consumption through efficient energy transfer and achieving energy saving and environmental protection effects. The heat pump system 40 includes a drying tunnel shell 42, and an evaporator 43 and a condenser 44, both disposed within the drying tunnel shell 42. The drying tunnel shell 42 provides a closed space for hot airflow to pass through it. Understandably, along the flow direction of the gas within the drying tunnel shell 42, the condenser 44 is located downstream of the evaporator 43. The function of the evaporator 43 is to absorb the humid heat of the airflow within the drying tunnel shell 42, causing the moisture in the airflow to condense and be discharged, thereby reducing the humidity of the airflow and making it dry. The condenser 44 then functions after the airflow passes through the evaporator 43, releasing the heat absorbed by the refrigerant in the evaporator 43 into the airflow, thereby heating the dried air to obtain dry, hot air.

[0050] The drying tunnel shell 42 is at least connected to the first drum 20, that is, the dry hot air flow after being processed by the evaporator 43 and the condenser 44 can flow into the first drum 20, so that the first drum 20 has a drying function, which can accelerate the evaporation of moisture from the clothes in the first drum 20 and achieve a highly efficient drying function.

[0051] Furthermore, at least a portion of the drying tunnel shell 42 is disposed between at least two second rollers 30 in the left-right direction, making full use of the gap between the second rollers 30, thereby improving the utilization rate of the internal space of the garment processing equipment 100 within a limited volume, and making the overall structural layout of the garment processing equipment 100 more compact.

[0052] Because at least a portion of the drying tunnel shell 42 is positioned between at least two second rollers 30 along the left-right direction, the weight distribution and stress on the left and right sides of the garment processing equipment 100 are relatively balanced. This balanced layout helps ensure the overall stability of the equipment during operation, especially during dynamic operations such as roller rotation and hot air circulation. The second rollers 30 on the left and right sides cooperate with the drying tunnel shell 42 to form a relatively symmetrical structure, effectively suppressing vibrations and shaking generated by the garment processing equipment 100 during operation, thereby achieving a more stable operating state.

[0053] Furthermore, positioning the drying tunnel shell 42 between at least two second rollers 30 helps lower the center of gravity of the entire garment processing equipment 100. Because the drying tunnel shell 42 and its internal components such as the evaporator 43 and condenser 44 have a certain weight, placing it at a lower position between the second rollers 30 lowers the equipment's center of gravity. Compared to placing the drying tunnel shell 42 at the top or other higher positions of the equipment, this design makes the equipment more stable during operation, reduces the risk of swaying and tipping due to a high center of gravity, and improves the safety and reliability of the equipment.

[0054] It should be noted that the first drum 20 is a drying drum, while the second drum 30 is at least a washing drum. If the first drum 20 is designed for washing purposes, it would typically require connecting and externally arranging water inlet and outlet pipes, which would occupy a significant amount of space. However, in this embodiment, the first drum 20 functions as a drying drum, effectively reducing the need for external space and allowing the entire garment handling device 100 to maintain both drying and washing functions while being smaller in size. Furthermore, if the overall volume of the garment handling device 100 remains constant, the reduced space occupied by the first drum 20 as a drying drum allows for a corresponding increase in the size of the second drum 30, thereby enhancing its capacity to hold more laundry.

[0055] In some embodiments, at least one second drum 30 is a washer-dryer drum. Using a washer-dryer combo allows the washing and drying steps to be completed in one go, eliminating the need to manually transfer clothes from the washing drum to the drying drum, thus saving users significant time and effort. The drying duct shell 42 is also connected to the second drum 30 to supply hot airflow to it. In other words, the first drum 20 (drying drum) and the second drum 30 share the drying duct shell 42. Sharing the drying duct shell 42 means that a separate hot air supply system does not need to be designed for each drum, thereby saving internal space, making the equipment more compact, and reducing overall complexity and cost.

[0056] Understandably, when at least two second rollers 30 are washing and drying rollers, the drying tunnel shell 42 can be connected to all the second rollers 30, that is, all the second rollers 30 and the first roller 20 share the same drying tunnel shell 42. The heat pump system 40 can provide hot airflow for multiple rollers, eliminating the need to design a separate hot air supply system for each roller, reducing the size and complexity of the garment processing equipment 100, and making the internal layout more compact.

[0057] Please see Figure 1 and Figure 2 Specifically, the drying tunnel shell 42 includes an air inlet shell 422 and two evaporator shells 421 connected sequentially from front to back. The air inlet shell 422 is connected to the front end of the two evaporator shells 421 and is used to introduce the hot and humid gas to be treated into the drying tunnel cavity. The evaporator 43 and the condenser 44 are arranged in the two evaporator shells 421 in the front-back direction. The two evaporator shells 421 are located between at least two second rollers 30, making full use of the space between at least two second rollers 30, so that the internal structure of the clothing processing equipment 100 is more compact.

[0058] Furthermore, the two shells 421 are centrally positioned along the left-right direction, which better balances the space on both sides. The centrally positioned shells 421 ensure that the remaining space on both sides is approximately equal. This allows for a more rational arrangement of other components within the space on both sides. Moreover, when the dried hot airflow, processed by the evaporator 43 and condenser 44, flows within the two shells 421, the centrally positioned shells 421 reduce the flow resistance of the hot air in the left-right direction. Because the space on both sides is symmetrical when the hot air flows in the central channel, it is not restricted by the narrow space on one side as in an offset configuration, thus enhancing the flow of the hot air and allowing it to reach each drum more quickly and smoothly, further improving drying efficiency.

[0059] It should be noted that the centrally positioned arrangement of the two housings 421 in the left-right direction is not an absolute geometric symmetry, but rather within a reasonable error range. That is, slight offsets of the two housings 421 relative to the center lines of at least two second rollers 30 are allowed in the left-right direction. This offset generally does not exceed a certain proportion (e.g., 5%) of the diameter of the second rollers 30 to accommodate tolerance requirements in actual manufacturing and assembly processes. In other words, the position of the two housings 421 in the left-right direction can be slightly to the left or right. As long as such offsets do not substantially affect the overall performance and function of the garment processing equipment 100, they should be considered within the range of "centrally positioned" in this application.

[0060] In some embodiments, the garment processing device 100 includes a housing 10 having a mounting cavity, within which a first roller 20, at least two second rollers 30, and a heat pump system 40 are located. Specifically, the housing 10 includes a base 11 and a housing, the housing being connected to the base 11 and enclosing the mounting cavity. The base 11 also has the aforementioned drying tunnel shell 42, which, together with the base 11, defines the drying tunnel cavity. The evaporator 43 and the condenser 44 are both located within the drying tunnel cavity, i.e., on the base 11. The base 11 serves as a mounting foundation, providing a robust support surface for the garment processing device 100, while the housing protects the internal structure of the garment processing device 100 from external environmental influences.

[0061] The base 11 can be made of steel plate or aluminum alloy plate. Steel plate has good strength and durability, making it suitable for heavy-duty bases 11. Aluminum alloy plate is lighter and has good corrosion resistance, making it suitable for lightweight garment handling equipment 100. The outer shell can be made of stainless steel or galvanized steel. Stainless steel shell is corrosion-resistant and easy to clean, while galvanized steel shell is relatively inexpensive and has good corrosion resistance.

[0062] It should be noted that the housing 10 is a standard-sized housing 10. All components, including the first roller 20, at least two second rollers 30, and the heat pump system 40, are concentrated inside the housing 10. This design makes the equipment structure relatively compact and facilitates centralized management and maintenance.

[0063] To facilitate a detailed explanation of the technical solution later, the following description will use a configuration of two second rollers 30 as an example. However, it should be noted that this technical solution is also applicable to situations where the number of second rollers 30 is three, four, or more. In practical applications, the number of second rollers 30 can be adjusted accordingly based on specific requirements.

[0064] like Figure 1 and Figure 2As shown, in some embodiments, two second rollers 30 are provided, both located below the first roller 20. Along the vertical direction of the garment processing device 100, the projections of the two second rollers 30 are at least partially within the projection of the first roller 20. That is, by placing the second rollers 30 below the first roller 20 and without exceeding the vertical projection range of the first roller 20, the internal space of the garment processing device 100 can be utilized more effectively, resulting in a more compact overall design. This layout makes the garment processing device 100 more regular in shape, contributing to improved aesthetics.

[0065] Furthermore, the two second rollers 30 are symmetrically arranged in the left-right direction about the plane of symmetry, while the rotation axis of the first roller 20 is located within the plane of symmetry. The symmetrical arrangement of the two second rollers 30 can improve the load balance on both sides of the garment processing equipment 100 during operation, reduce vibration caused by uneven weight distribution, and improve stability and durability.

[0066] Please continue reading. Figure 1 and Figure 2 In some embodiments, the housing 10 further includes a bottom plate 12, which is disposed on the base 11. The bottom plate 12 may be located above or below the base 11, and the placement of the bottom plate 12 can significantly enhance the structural strength of the base 11. It should be noted that the bottom plate 12 does not necessarily need to completely cover the base 11. In some designs, the bottom plate 12 may cover a portion of the base 11, while the second roller 30 is disposed on the bottom plate 12 and / or the base 11. When the bottom plate 12 is provided, the drying tunnel shell 42, together with the base 11 and / or the bottom plate 12, defines the aforementioned drying tunnel cavity.

[0067] The base plate 12 can better support the weight of the second roller 30 and the clothes. During the operation of the clothing processing equipment 100, especially when the roller rotates, a certain amount of vibration and impact will be generated. The base plate 12 can more stably support the second roller 30, avoid deformation or damage caused by insufficient strength of the base 11, ensure the stability of the equipment during operation, and reduce the risk of equipment displacement or tipping caused by vibration.

[0068] Reducing the coverage area of ​​the base plate 12 can provide more precise local support based on the weight distribution and stress of the second roller 30. Setting the base plate 12 in key areas can provide additional strength and stability, and can also reduce the overall weight of the box 10 and reduce material costs.

[0069] Specifically, the base plate 12 can be a sheet metal base plate, a carbon steel base plate, or an aluminum base plate. A stronger base plate 12 can effectively resist deformation and damage caused by factors such as gravity and vibration during long-term use. For example, in the case of frequent use of the garment processing equipment 100, the base plate 12 needs to withstand repeated load changes. The reinforced base plate 12 can better maintain its shape and performance, avoid problems such as dents and cracks, thereby extending the overall service life of the garment processing equipment 100 and reducing the repair and replacement costs caused by damage to the base plate 12.

[0070] In some embodiments, the base plate 12 includes a main plate and a left folding plate and a right folding plate connected to the main plate. The main plate is provided with the aforementioned drying tunnel shell 42, evaporator 43, and condenser 44. The left folding plate and the right folding plate are arranged opposite each other in the left-right direction. Both the left folding plate and the right folding plate are folded upwards and extended. Understandably, the main plate, the left folding plate, and the right folding plate are integrally formed components. The outer shell includes a left side plate and a right side plate arranged opposite each other in the left-right direction. The left side plate is connected to the left folding plate and is located between the left folding plate and a second roller 30. The right side plate is connected to the right folding plate and is located between the right folding plate and another second roller 30. Folding up the left and right sides of the base plate 12 to form the left folding plate and the right folding plate can enhance the lateral support of the base plate 12. The left folding plate and the right folding plate are respectively connected to the left side plate and the right side plate. This connection method helps to more tightly integrate the base plate 12 with the outer shell, forming a more robust integral structure. This structure not only improves the overall rigidity of the equipment, but also enhances its protection against external impacts.

[0071] Furthermore, the bottom plate 12 also includes a rear folding plate, and the outer shell also includes a back shell. The back shell is connected to the rear folding plate and is located between the rear folding plate and the drying tunnel shell 42, which enhances the back support of the box 10 and helps to more tightly integrate the bottom plate 12 and the back shell, thereby enhancing the structural stability and deformation resistance of the box 10.

[0072] Please continue reading. Figure 1 and Figure 2 In some embodiments, the garment processing device 100 further includes a drive system 50 for driving the first roller 20 and two second rollers 30 to rotate. The drive system 50 includes a drive motor connected to at least one of the first roller 20 and the two second rollers 30. The drive motor is disposed on the base 11 and located behind one of the second rollers 30. The length of the second roller 30 is shorter than the length of the first roller 20. That is, within the projection of the first roller 20 in the vertical direction, there is still an installation space between the second roller 30 and the back shell that can be used to install the drive motor, maximizing the use of available space. This design reduces the overall external extension of the garment processing device 100, making the entire garment processing device 100 more compact.

[0073] Optionally, the drive system 50 adopts a direct-drive or transmission-type drive method. For example, in the direct-drive method, the drive motor is directly mounted on the bottom of the first roller 20 and the second roller 30, respectively. The first roller 20 and the second roller 30 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-type drive method, the power of the drive motor is transmitted to the first roller 20 and the second roller 30 through transmission structures such as belts, gears, and chains. This drive method has lower cost and maintenance cost, and can realize multiple drive modes.

[0074] In this embodiment, the drive motor located behind the second roller 30 is used to drive the first roller 20 to rotate in a transmission manner, while the second roller 30 is driven to rotate by a direct drive motor.

[0075] Please continue reading. Figure 1 and Figure 2 In some embodiments, the heat pump system 40 further includes a compressor 41. Refrigerant flows through the heat pump system 40. The compressor 41 compresses the refrigerant and discharges it at high pressure. The discharged high-pressure refrigerant enters the condenser 44, is cooled by ambient air, and condenses into a high-pressure liquid (simultaneously transferring heat to the surrounding air). The compressor 41 is mounted on the base 11 and located behind the other second roller 30. Understandably, the compressor 41 and the drive motor are spaced apart on the base 11 in the left-right direction, making the arrangement within the second chamber more reasonable and compact, effectively utilizing the space on the main board. Furthermore, both the compressor 41 and the drive motor are located behind the two second rollers 30, specifically on the side opposite to the inlet of the second roller 30. This balances the weight of the clothing handling device 100 in the front-back direction, enhancing operational stability. Additionally, the user can still easily access the inlet of the second roller 30 from the front of the clothing handling device 100 to add or remove clothing.

[0076] Specifically, the air inlet shell 422 is connected to the first drum 20, allowing the hot and humid air inside the first drum 20 to directly and quickly enter the air inlet shell 422. During the drying process, after the hot air inside the first drum 20 removes moisture from the clothes, it needs to be processed again by the heat pump system 40 to restore dryness and heat. This connection method acts like a "fast track," reducing the path and resistance of the hot air from the first drum 20 to the heat pump system 40, thus improving the efficiency of hot air circulation. When the hot air from the first drum 20 enters the air inlet shell 422, it can flow more quickly to the evaporator 43 and condenser 44 for dehumidification and heating, instead of going through complex pipes inside the equipment, thereby shortening the hot air circulation time and accelerating the drying process.

[0077] Furthermore, at least a portion of the air inlet housing 422 is located between at least two second rollers 30; that is, either a portion or the entire air inlet housing 422 may be located between at least two second rollers 30, thus making full use of the gap space between the second rollers 30. In the design of the garment processing equipment 100, space is a very precious resource. This layout avoids additional space waste, making the internal structure of the equipment more compact.

[0078] Next, the operating mechanism of the second roller 30 when it has a drying function will be described in detail. Regarding how to supply hot air to the second roller 30, this application provides the following two implementation methods: First, dry hot air that has been processed by the evaporator 43 and condenser 44 in the drying chamber can be introduced to dry the clothes; Second, the clothes processing equipment 100 also includes a special drying device, which is responsible for generating and supplying hot air to achieve the drying treatment of the clothes in the second roller 30.

[0079] In another configuration, the garment processing equipment 100 also includes a drying device (not shown). The drying device is connected to the housing 10, which provides stable support for the drying device, allowing it to operate stably along the vertical direction of the garment processing equipment 100. The drying device is located between the first roller 20 and the second roller 30. This arrangement makes the overall structure of the garment processing equipment 100 more compact and effectively utilizes the gap between the first roller 20 and the second roller 30 in the vertical direction. The drying device is connected to the second garment processing chamber 31 and can introduce hot air into the second roller 30.

[0080] Specifically, the drying device includes a heating element and a flow guiding structure arranged in a front-to-back direction. The heating element is installed in the housing 10 and is used to heat the gas. One end of the flow guiding structure is connected to the heating element, and the other end is connected to the second drum 30. The flow guiding structure is used to guide the gas heated by the heating element into the second drum 30. The drying device also has an air inlet with a filter screen to pre-treat the air entering the drying device, ensuring the cleanliness of the hot air and improving drying efficiency and the drying quality of the clothes. Auxiliary air vents connected to the outside are provided on both the left and right side panels. These auxiliary air vents are connected to the air inlet, improving the air circulation efficiency inside the drying device and helping to dry clothes faster.

[0081] Furthermore, the flow guiding structure includes a first flow guiding section and a second flow guiding section connected to the first flow guiding section. The first flow guiding section extends in the front-back direction. The end of the first flow guiding section away from the second flow guiding section is connected to the heating body. The second flow guiding section is set at an angle to the first flow guiding section. The end of the second flow guiding section away from the first flow guiding section is connected to the second roller 30. The second flow guiding section can change the flow direction of the hot air so that it communicates with the second clothing processing chamber 31.

[0082] Furthermore, when both second rollers 30 are washing and drying rollers, there are also two drying devices, which are set one-to-one with the two second rollers 30. The two drying devices are respectively connected to the left and right sides of the housing 10 and are respectively connected to the two second garment processing chambers 31. Each drying device corresponds to one second roller 30 and can be controlled independently, providing users with greater operational flexibility and allowing the simultaneous or separate use of each second roller 30 for drying.

[0083] Along the vertical direction, the projections of the two drying devices are located within the projection of the first roller 20. Since the first roller 20 is set up lying down in its cylindrical shape, its vertical cross-section presents a circle. The cylindrical design of the first roller 20 naturally forms two empty areas on both sides of its bottom, namely the lower left and lower right corners, similar to the "armpit" position of the first roller 20. The two drying devices are respectively installed in the two "armpits", which can maximize the use of the internal space of the clothing processing equipment 100 and avoid interfering with the first roller 20.

[0084] Furthermore, the two drying devices are arranged symmetrically in the left-right direction about the plane of symmetry, and the rotation axis of the first roller 20 is located within the plane of symmetry. The symmetrical layout helps to improve the stability and safety of the clothing processing equipment 100, because the evenly distributed load can reduce the vibration of the equipment and make the operation more stable.

[0085] Then, regarding the second roller 30, assuming it has a drying function, the humid and hot gas inside can be treated in two ways: first, by exhausting the humid and hot gas to the outside of the clothing processing equipment 100; second, by circulating the humid and hot gas into the drying chamber for dehumidification and heating. Both methods aim to achieve the desired drying effect while optimizing energy efficiency and user experience. These two methods will be discussed in detail below.

[0086] In one configuration, the outer casing also includes a panel arranged opposite to the back casing in the front-to-back direction. The panel has an exhaust vent that communicates with the second drum 30 (washing and drying drum) to expel hot and humid air from inside the second drum 30. Understandably, the second drum 30 is close to the exhaust vent on the panel, which helps to directly and efficiently expel the hot and humid air, reducing its circulation within the garment processing equipment 100. External exhaust allows the hot and humid air to be directly discharged to the outside of the garment processing equipment 100, reducing the growth of bacteria and mold and maintaining the cleanliness and hygiene inside the garment processing equipment 100.

[0087] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
