Detailed Implementation

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] Please see Figure 1 This application provides a garment processing device 100, which includes a first drum 10 and at least two second drums 20. The multi-drum 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.

[0076] In this embodiment, the central axis of the first roller 10 is parallel to the central axis of the second roller 20. This parallel axis design makes more efficient use of space, allowing the first roller 10 and at least two second rollers 20 to be arranged compactly, which is suitable for environments with limited space. Furthermore, the central axes of both the first roller 10 and the second roller 20 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 10 and the second roller 20 can maintain a stable operating state during rotation, reducing vibration and noise caused by tilting, thereby improving the overall performance of the equipment.

[0077] In other embodiments, the central axis of the first roller 10 may not be parallel to the central axis of the second roller 20, or both the central axes of the first roller 10 and the second roller 20 may be set at an angle to the horizontal direction. This application does not impose any limitations on this.

[0078] At least two second rollers 20 are arranged at intervals in the left-right direction and are located below the first roller 10. Understandably, the loading ports of both the first roller 10 and the second roller 20 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 20 are on the same horizontal plane, arranged at a certain interval. The number of second rollers 20 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 20 below the first roller 10 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.).

[0079] The diameter of the second roller 20 is smaller than that of the first roller 10. By arranging at least two smaller diameter second rollers 20 below the first roller 10, 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.

[0080] The garment processing equipment 100 also includes a base 64, which is located at the bottom of the garment processing equipment 100. At least the second roller 20 is disposed on the base 64. In related technologies, the second roller is usually connected to an integrally bent thin-walled plate. The structural strength of the thin-walled plate is relatively weak, and it is prone to deformation during long-term use, especially when the second roller vibrates. In this embodiment, the second roller 20 is disposed on the base 64, which has a thicker wall and stronger resistance to deformation, providing more stable support for the second roller 20.

[0081] The base 64 can be made of plastic and is integrally injection molded. By setting receiving grooves or other means, the weight of multiple second rollers can be distributed to a wider area.

[0082] like Figure 2 and Figure 3 As shown, the garment processing equipment 100 also includes a heat pump system 30, 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 30 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 30 includes a drying tunnel shell 31, and an evaporator 32 and a condenser 33, both disposed within the drying tunnel shell 31. The drying tunnel shell 31 provides a flow space for hot air to flow within it. Understandably, along the flow direction of the gas within the drying tunnel shell 31, the condenser 33 is located downstream of the evaporator 32. The function of the evaporator 32 is to absorb the humid heat of the airflow within the drying tunnel shell 31, causing the moisture in the airflow to condense and be discharged, thereby reducing the humidity of the airflow and making it dry. The condenser 33 then functions after the airflow passes through the evaporator 32, releasing the heat absorbed by the refrigerant in the evaporator 32 into the airflow, thereby heating the dried air to obtain dry, hot air.

[0083] The drying tunnel shell 31 is at least connected to the first drum 10, that is, the dry hot air flow after being processed by the evaporator 32 and the condenser 33 can flow into the first drum 10 so that the first drum 10 has a drying function, which can accelerate the evaporation of moisture from the clothes in the first drum 10 and achieve a highly efficient drying function.

[0084] Please continue reading. Figure 2 Furthermore, at least a portion of the drying tunnel shell 31 is disposed between at least two second rollers 20 in the left-right direction, making full use of the gap between the second rollers 20, 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.

[0085] It should be noted that the first drum 10 is a drying drum, while the second drum 20 is at least a washing drum. If the first drum 10 is designed for washing purposes, it would typically require connecting and arranging water inlet and outlet pipes below it, which would occupy a significant amount of space. However, in this embodiment, the first drum 10 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 10 as a drying drum allows for a corresponding increase in the size of the second drum 20, thereby enhancing its capacity to hold more laundry.

[0086] In some embodiments, at least one second drum 20 is a washer-dryer drum. Using a washer-dryer combo can complete the washing and drying steps in one go, eliminating the need to manually transfer clothes from the washing drum to the drying drum, thus saving users time and effort by eliminating intermediate steps.

[0087] In some embodiments, the drying duct shell 31 is also connected to the washing and drying drum to supply hot airflow to the washing and drying drum. That is, the first drum 10 (drying drum) and the washing and drying drum share the drying duct shell 31. Sharing the drying duct shell 31 means that there is no need to design a separate hot air supply system for each drum, thereby saving internal space of the equipment, making the equipment more compact, and reducing the overall complexity and cost of the equipment.

[0088] Understandably, when at least two second rollers 20 are washing and drying rollers, the drying tunnel shell 31 can be connected to all the second rollers 20, that is, all the second rollers 20 and the first roller 10 share the same drying tunnel shell 31. The heat pump system 30 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.

[0089] Please see Figure 3 and Figure 4 Specifically, the heat pump system 30 also includes a fan 35, and the drying tunnel shell 31 includes an air inlet shell 311, two-evapor shells 312, and an exhaust shell 313 connected sequentially from front to back. The air inlet shell 311 is connected to the front end of the two-evapor shells 312 and is used to introduce the hot and humid gas to be treated into the drying tunnel cavity. The evaporator 32 and the condenser 33 are arranged in the front-back direction within the two-evapor shells 312, which are located between at least two second rollers 20, making full use of the space between at least two second rollers 20, thus making the internal structure of the clothing processing equipment 100 more compact. The exhaust shell 313 is connected to the rear end of the two-evapor shells 312, and a fan 35 can be installed inside the exhaust shell 313. The fan 35 can discharge the treated dry hot gas into the first roller 10 and / or the second roller 20 (washing and drying rollers) connected to it, improving the continuity of gas flow and accelerating the drying process of the clothes.

[0090] In some embodiments, the garment processing device 100 includes a housing 60 and / or a base plate 61. The housing 60 has a mounting cavity 60a, within which a first roller 10, at least two second rollers 20, and a heat pump system 30 are located. A base 64 is disposed at the bottom of the housing 60, and a drying tunnel shell 31 is disposed on the base 64. The drying tunnel shell 31 and the base 64 enclose and define a drying tunnel cavity, where both the evaporator 32 and the condenser 33 are located. That is, the evaporator 32 and the condenser 33 are located on and supported by the base 64. In practical installations, multiple receiving slots can be provided on the base 64 as preset installation positions. The evaporator 32 and the condenser 33 can be disposed within the receiving slots. The base 64 facilitates the integration of more functional modules.

[0091] The base 64 itself possesses sufficient structural strength and support capacity to undertake the basic function of the base plate 61; therefore, the installation of the base plate 61 is optional. Understandably, in other embodiments, the base plate 61 may not be provided. In this embodiment, a base plate 61 is provided, and the base 64 is disposed on the base plate 61. This not only further reduces the local stress on the base plate 61 and reduces the risk of deformation or damage to the base plate 61, but also provides a more robust bottom support surface for the garment processing device 100.

[0092] In this embodiment, the garment processing device 100 is provided with a housing 60 and a base plate 61. Specifically, the housing 60 includes an outer shell 63, which is connected to the base plate 61 and together with the base plate 61 forms an installation cavity 60a. The outer shell 63 can protect the internal structure of the garment processing device 100 from the influence of the external environment from the periphery.

[0093] The base plate 61 can be made of steel plate or aluminum alloy plate. Steel plate has good strength and durability, making it suitable for heavy-duty base plates 61. Aluminum alloy plate is lighter and has good corrosion resistance, making it suitable for lightweight garment handling equipment 100. The outer shell 63 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.

[0094] like Figure 1As shown, the housing 60 also includes a support frame 62, which is disposed within the outer shell 63. The support frame 62 can support the base plate 61 or the base 64, thereby enhancing the overall strength and making the garment processing equipment 100 more stable. The support frame 62 includes at least a front support beam 621, which is connected to the front side of the base plate 61 or the base 64. The drying tunnel shell 31 is connected to the front support beam 621, and the front support beam 621 can limit the air inlet shell 311 in the drying tunnel shell 31, so that at least a portion of the air inlet shell 311 is located between at least two second rollers 20. The front support beam 621 can be in the shape of a "П". The front support beam 621 divides the mounting cavity 60a into a first chamber 60b and a second chamber 60c along the vertical direction. It should be noted that the front support beam 621 does not separate the first chamber 60b and the second chamber 60c. The first chamber 60b and the second chamber 60c are interconnected. The first roller 10 can be located in the first chamber 60b, while at least two second rollers 20 are located in the second chamber 60c. This can make more efficient use of space, allowing the first roller 10 and at least two second rollers 20 to be installed in different chambers, resulting in a more regular arrangement.

[0095] To facilitate a detailed explanation of the technical solution later, the following description will use a configuration of two second rollers 20 as an example. However, it should be noted that this technical solution is also applicable to situations where the number of second rollers 20 is three, four, or more. In practical applications, the number of second rollers 20 can be adjusted accordingly based on specific requirements.

[0096] In this embodiment, two second rollers 20 are provided, both located below the first roller 10. Along the vertical direction of the garment processing device 100, the projections of the two second rollers 20 are within the projection of the first roller 10. That is, by placing the second rollers 20 below the first roller 10 and within the vertical projection range of the first roller 10, 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.

[0097] Furthermore, the two second rollers 20 are arranged symmetrically in the left-right direction about the plane of symmetry, while the rotation axis of the first roller 10 is located within the plane of symmetry. The symmetrical arrangement of the two second rollers 20 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.

[0098] like Figure 1 , Figure 3 and Figure 5As shown, in some embodiments, the base plate 61 includes a main plate 611 and a left folding plate 612 and a right folding plate 613 connected to the main plate 611. The main plate 611 is provided with the aforementioned base 64, while the left folding plate 612 and the right folding plate 613 are arranged opposite each other in the left-right direction. Both the left folding plate 612 and the right folding plate 613 are folded upwards and extended. Understandably, the main plate 611, the left folding plate 612 and the right folding plate 613 are integrally formed components. The outer casing 63 includes a left side plate 631 and a right side plate 632 arranged opposite each other in the left-right direction. The left side plate 631 is connected to the left folding plate 612 and is located between the left folding plate 612 and a second roller 20. The right side plate 632 is connected to the right folding plate 613 and is located between the right folding plate 613 and another second roller 20. Folding up the left and right sides of the base plate 61 to form the left folding plate 612 and the right folding plate 613 enhances the lateral support of the base plate 61. The left folding plate 612 and the right folding plate 613 are respectively connected to the left side plate 631 and the right side plate 632. This connection method helps to more tightly integrate the base plate 61 with the outer casing 63, forming a more robust overall structure. This structure not only improves the overall rigidity of the equipment but also enhances its protection against external impacts.

[0099] Please continue reading. Figure 1 and Figure 3 Furthermore, the base plate 61 also includes a rear folding plate 614, which is arranged opposite to the front support beam 621. The outer shell 63 also includes a back shell 633, which is connected to the rear folding plate 614 and located between the rear folding plate 614 and the drying tunnel shell 31. This enhances the back support of the box 60 and helps to more tightly integrate the base plate 61 and the back shell 633, thereby enhancing the structural stability and deformation resistance of the box 60.

[0100] In some embodiments, the garment processing device 100 further includes a drive system 40 for driving the first roller 10 and two second rollers 20 to rotate. The drive system 40 includes a drive motor 41 connected to at least one of the first roller 10 and the two second rollers 20. The drive motor 41 is disposed on the base 64 and located behind one of the second rollers 20. The length of the second roller 20 is shorter than the length of the first roller 10. That is, within the projection of the first roller 10 in the vertical direction, there is also an installation space between the second roller 20 and the back shell 633 for installing the drive motor 41, 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.

[0101] Optionally, the drive system 40 adopts a direct-drive or transmission-type 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. 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-type 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.

[0102] In this embodiment, the drive motor 41 located behind the second roller 20 is used to drive the first roller 10 to rotate in a transmission manner, while the second roller 20 is driven to rotate by a direct drive motor.

[0103] like Figure 3 As shown, in some embodiments, the heat pump system 30 also includes a compressor 34. Refrigerant flows through the heat pump system 30. The compressor 34 compresses the refrigerant 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 (simultaneously transferring heat to the surrounding air). The compressor 34 is mounted on the base 64 and located behind the other second roller 20. Understandably, the compressor 34 and the drive motor 41 are spaced apart on the base 64 in the left-right direction, making the arrangement within the second chamber 60c more reasonable and compact, effectively utilizing the space on the main board 611. Furthermore, both the compressor 34 and the drive motor 41 are located behind the two second rollers 20, specifically on the side away from the inlet of the second roller 20. 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 20 from the front of the clothing handling device 100 to add or remove clothing.

[0104] First, the first drum 10 is equipped with a main air inlet (not shown). The main air inlet can be located at the rear cover of the first drum 10. The main air inlet is connected to the exhaust shell 313 of the drying tunnel shell 31. That is, the dry hot gas processed by the evaporator 32 and condenser 33 can be introduced into the first drum 10 through the main air inlet. The main air inlet can be located at a relatively close distance between the rear cover of the first drum 10 and the exhaust shell 313, which can quickly introduce dry hot gas into the first drum 10 to dry the clothes inside the first drum 10. The first drum 10 is also equipped with a main air outlet, which can be located at the door seal of the first drum 10. Dry hot gas flows from the rear end to the front end of the first drum 10 and comes into uniform contact with the clothes to be treated inside the first drum 10. The main air outlet is connected to the air inlet shell 311 of the drying tunnel shell 31, so that the humid hot air that has come into contact with the clothes is introduced into the drying tunnel cavity again and continues to participate in the heat exchange process in the heat pump system 30. The recirculation of humid hot gas helps to maintain the temperature and humidity balance in the drying tunnel cavity and further enhances the drying effect.

[0105] like Figure 1 As shown, specifically, the support frame 62 also includes a front support member 622, which is connected to the front support beam 621 and located above the front support beam 621. The front support member 622 is used to support at least the front end of the first roller 10. The main air outlet is specifically located below the door seal of the first roller 10. The front support member 622 has an air outlet channel connecting the main air outlet and the air inlet shell 311 of the drying tunnel shell 31, so that the hot and humid gas inside the first roller 10 can be discharged into the drying tunnel cavity through the air outlet channel. The front support member 622 not only supports the first roller 10 but also serves as a connection, effectively utilizing the space.

[0106] Next, the operating mechanism of the second drum 20 when it has a drying function will be described in detail. Regarding how to supply hot air to the second drum 20, this application provides the following two implementation methods: First, dry hot air that has been processed by the evaporator 32 and condenser 33 in the drying chamber can be introduced to dry the clothes; Second, the clothes processing equipment 100 also includes a special drying device 50, which is responsible for generating and supplying hot air to achieve the drying treatment of the clothes in the second drum 20.

[0107] like Figure 6 and Figure 13As shown, in one configuration, the second roller 20 is provided with a sub-air inlet 20b, which can be located at the rear cover of the second roller 20. The heat pump system 30 also includes a diverter assembly 36, which is connected to the exhaust shell 313 of the drying tunnel shell 31. Understandably, the sub-air inlet 20b is located at the rear cover of the second roller 20, close to the exhaust shell 313, which helps to directly and efficiently introduce dry hot gas into the second roller 20. The diverter assembly 36 is used to divert the dry hot gas in the drying tunnel cavity to the main air inlet and at least two sub-air inlets 20b, thereby realizing independent or coordinated drying of the first roller 10 and at least two second rollers 20. This allows the heat pump system 30 to adjust the distribution of hot air according to actual needs, enhancing the flexibility and adaptability of the heat pump system 30. For example, when the user does not use the drying function of the second drum 20 (washer-dryer drum), the diverter assembly 36 can be adjusted so that hot air does not flow into the second drum 20, avoiding unnecessary energy waste, because the hot air will only be guided to the drum that needs to be dried, reducing energy consumption.

[0108] Please continue reading. Figure 6 and Figure 13 Specifically, the diversion pipe assembly 36 includes at least one air duct 361 and at least one switch structure 362. One end of the air duct 361 is connected to the exhaust shell 313 of the drying tunnel shell 31, and the other end is connected to the rear cover of the second roller 20. That is, the air duct 361 can communicate with the sub-air inlet 20b, allowing the hot airflow in the drying tunnel cavity to flow into the second roller 20. The air duct 361 is responsible for effectively transporting the hot airflow in the drying tunnel cavity into the second roller 20, realizing the transfer of hot airflow. The switch structure 362 is disposed between the air duct 361 and the exhaust shell 313. The switch structure 362 is used to selectively connect or disconnect the air duct 361 and the exhaust shell 313. When the second roller 20 does not require the drying function, the switch structure 362 can be disconnected to prevent unnecessary hot airflow from flowing in and save energy.

[0109] Understandably, each second roller 20 is connected to an air duct 361, ensuring a stable airflow supply for each roller and enabling independent drying control. This means that different second rollers 20 can each perform different drying programs simultaneously, or adjust the airflow according to the type of clothing and drying needs.

[0110] Among them, duct 361 is a corrugated pipe. Corrugated pipes can expand and contract to a certain extent to adapt to length changes caused by temperature changes and reduce stress caused by thermal expansion and contraction. In addition, corrugated pipes have good bending performance, which can easily adapt to complex installation paths and space constraints, without too many joints. They can also withstand a certain pressure while maintaining good structural stability, making them suitable for pressure changes in heat pump system 30.

[0111] Furthermore, the switching structure 362 includes a switching valve (not shown) and a switching motor (not shown). The switching valve is located at the connection between the air duct 361 and the exhaust shell 313, while the switching motor is connected to the switching valve to drive the switching valve to connect or disconnect the air duct 361 and the exhaust shell 313. The switching valve can also regulate the amount of drying hot gas flowing to the second drum 20. The switching motor is connected to the switching valve to provide power, so that the switching valve can automatically open or close according to the control signal. It can also precisely control the opening and closing degree of the switching valve, thereby achieving fine adjustment of the airflow to meet the air demand of different drying stages.

[0112] like Figure 7 and Figure 8 As shown, in another configuration, the support frame 62 further includes a side support beam 623 connected to the front support beam 621 and the back shell 633. The garment processing device 100 also includes a drying device 50 connected to the side support beam 623, which provides stable support for the drying device 50, enabling it to operate stably along the vertical direction of the garment processing device 100. The drying device 50 is located between the first roller 10 and the second roller 20. This arrangement makes the overall structure of the garment processing device 100 more compact and effectively utilizes the gap between the first roller 10 and the second roller 20 in the vertical direction. The drying device 50 is connected to the sub-air inlet 20b, allowing it to introduce hot air into the second roller 20.

[0113] Please continue reading. Figure 8 Specifically, the drying device 50 includes a heating body (not shown) arranged in a front-to-back direction and a flow guiding structure 52. The heating body is mounted on a side support beam 623 and is used to heat the gas. One end of the flow guiding structure 52 is connected to the heating body, and the other end is connected to the second drum 20. The flow guiding structure 52 is used to guide the gas heated by the heating body into the second drum 20. Since the sub-air inlet 20b of the second drum 20 is located on the rear cover, the heating body is located on the front side, and the flow guiding structure 52 is located on the rear side. This allows the gas heated by the heating body to be directly introduced into the second drum 20 through the flow guiding structure 52, reducing heat loss and improving heat utilization efficiency.

[0114] The drying unit 50 also has an air inlet (not shown), which is equipped with a filter to pre-treat the air entering the drying unit 50, ensuring the cleanliness of the hot air and improving drying efficiency and the quality of the dried clothes. Auxiliary air vents connected to the outside are provided on both the left side panel 631 and the right side panel 632. These auxiliary air vents are connected to the air inlet, improving the air circulation efficiency inside the drying unit 50 and helping to dry clothes faster.

[0115] Please continue reading. Figure 8Furthermore, the flow guiding structure 52 includes a first flow guiding section 521 and a second flow guiding section 522 connected to the first flow guiding section 521. The first flow guiding section 521 extends in the front-back direction. The end of the first flow guiding section 521 away from the second flow guiding section 522 is connected to the heating body. The second flow guiding section 522 is set at an angle to the first flow guiding section 521. The end of the second flow guiding section 522 away from the first flow guiding section 521 is connected to the second roller 20. The second flow guiding section 522 can change the flow direction of the hot air so that it communicates with the sub-air inlet 20b.

[0116] Please continue reading. Figure 8 Furthermore, the side support beam 623 specifically includes a left support beam 6231 and a right support beam 6232 arranged opposite to each other in the left-right direction. Both the left support beam 6231 and the right support beam 6232 are connected to the front support beam 621. When both second rollers 20 are washing and drying rollers, two drying devices 50 are also provided, corresponding one-to-one with the two second rollers 20. The two drying devices 50 are respectively connected to the left support beam 6231 and the right support beam 6232, and are respectively connected to the two sub-air inlet ports 20b. Each drying device 50 corresponds to one second roller 20 and can be controlled independently, providing users with greater operational flexibility and allowing the simultaneous or separate use of each second roller 20 for drying.

[0117] Along the vertical direction, the projections of the two drying devices 50 are located within the projection of the first roller 10. Since the first roller 10 is set up lying down in its cylindrical shape, its vertical cross-section presents a circle. The cylindrical design of the first roller 10 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 10. The two drying devices 50 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 10.

[0118] Furthermore, the two drying devices 50 are arranged symmetrically in the left-right direction about the plane of symmetry, and the rotation axis of the first roller 10 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.

[0119] Then, regarding the second roller 20, 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 a drying effect on the clothes while optimizing energy efficiency and user experience. These two methods will be discussed in detail below.

[0120] like Figure 13 As shown, in one configuration, the second drum 20 (washer-dryer drum) is provided with a sub-exhaust port 20a, which can be located at the door seal of the second drum 20. The outer casing 63 also includes a panel (not shown), which is arranged opposite to the back casing 633 in the front-to-back direction. The panel has an exhaust port (not shown), which is connected to the sub-exhaust port 20a of the second drum 20 (washer-dryer drum). The exhaust port is used to discharge the humid and hot air inside the second drum 20. Understandably, the sub-exhaust port 20a is located at the door seal of the second drum 20, which is close to the exhaust port of the panel, which helps to directly and efficiently discharge the humid and hot air and reduce the detour of the humid and hot air inside the garment processing equipment 100. The direct exhaust method can directly discharge the humid and hot air 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.

[0121] like Figure 5 , Figure 8 and Figure 13 As shown, in another configuration, the second drum 20 (washer-dryer drum) is equipped with a sub-air outlet 20a, which can be located at the door seal of the second drum 20. The sub-air inlet 20b can be flat and extends laterally. This flat design better accommodates the space constraints at the door seal of the second drum 20 (washer-dryer drum), resulting in a more compact structure and reduced space occupation within the garment processing equipment. It also provides a larger air outlet area, accelerating the removal of hot and humid gases.

[0122] like Figure 1 , Figure 5 and Figure 9 As shown, Figure 8 As shown, the garment processing equipment further includes a connecting member 90, which is connected to the housing 60 and specifically to the support frame 62. The connecting member 90 is arc-shaped, which can guide the flow direction of the airflow, reduce airflow turbulence and resistance, and improve the flow performance of the airflow. The two ends of the connecting member 90 are respectively connected to the second roller 20 and the front support member 622. The connecting member 90 is also supported by the front support beam 621. Understandably, the front support beam 621 is provided with an opening for the sub-air outlet 20a to pass through. The connecting member 90 has an exhaust channel, which is connected to the sub-air outlet 20a and the exhaust channel. This can effectively manage and optimize the flow path of the hot and humid airflow, so that the hot and humid gas can be smoothly discharged from the second roller 20 into the drying chamber. The hot and humid gas is directly discharged into the drying chamber, which can quickly dehumidify and recirculate, improving the drying efficiency.

[0123] Understandably, when both second rollers 20 are washing and drying rollers, there are two connecting parts 90, which are supported relative to each other on the front support beam 621 in the left and right direction. Each of the two second rollers 20 has an independent exhaust channel, which can effectively discharge the hot and humid gas from the second roller 20 and recover the heat energy through the heat exchange system in the drying tunnel, thereby improving energy utilization efficiency and reducing energy consumption.

[0124] Among them, the connecting member 90 and the front support member 622 can be an integral component. The design of an integral component can simplify the installation process, eliminating the need to install and connect multiple structures separately, thereby saving installation time. In addition, integral components usually have better structural stability and reduce connection points, thereby reducing the risk caused by improper connection.

[0125] To improve the circulation of hot and humid airflow into the drying tunnel, in some embodiments, the garment processing equipment 100 further includes a filter device (not shown). The filter device is used to filter the hot and humid airflow entering the drying tunnel, effectively filtering the hot and humid airflow entering the drying tunnel to remove lint, dust, and other particles generated during the drying process. The filtered hot and humid airflow is purer, reducing the accumulation of dirt on the evaporator 32 and condenser 33. When the filtered hot and humid airflow circulates into the first drum 10 and the second drum 20, it can provide cleaner hot air, which helps dry the clothes and reduces dust and lint on the clothes, thus improving the drying quality of the clothes.

[0126] In one configuration, filters are detachably connected to both the exhaust and outlet air ducts. These filters may have a multi-layered structure, including a pre-filter layer and a high-efficiency filter layer. The pre-filter layer intercepts larger fibers and impurities, while the high-efficiency filter layer captures even smaller particles. This ensures that impurities are effectively captured as the humid, hot airflow within the first roller 10 and the second roller 20 passes through the filters. The detachable filters can be removed for cleaning, facilitating subsequent maintenance.

[0127] In another configuration, a filter module is installed in the exhaust duct. The filter module is used to filter the airflow flowing through the exhaust duct. Specifically, the filter module has a main filter channel and two sub-filter channels. Understandably, the main filter channel is connected to the main air outlet, while the two sub-filters are connected to two sub-air outlets 20a respectively. The main filter channel and the two sub-filter channels are not connected to each other, that is, the hot and humid airflow discharged from the first roller 10 and the second roller 20 have independent paths to prevent cross-contamination of hot and humid airflow. When the first roller 10 and the two second rollers 20 use the drying function at the same time, the three streams of hot airflow after filtration converge in the air inlet shell 311.

[0128] In another configuration, the air outlet channels include a main air outlet channel and two sub-air outlet channels, enabling independent management of the hot and humid airflow discharged from the first roller 10 and the two second rollers 20. This avoids airflow mixing between different rollers and maintains the stability of the drying environment. The main air outlet channel and / or the two sub-air outlet channels are equipped with filters, as the hot and humid airflow discharged from the first roller 10 and the two second rollers 20 may contain impurities such as clothing fibers, dust, and hair. The filters effectively intercept these impurities, preventing them from entering the heat pump system 30. Specifically, the main air outlet channel is connected to the main air outlet interface and the air inlet shell 311; one sub-air outlet channel is connected to the sub-air outlet interface 20a and the air inlet shell 311; and the other sub-air outlet channel is connected to the other sub-air outlet interface 20a and the air inlet shell 311.

[0129] like Figure 10 and Figure 11 As shown, to improve user convenience, the garment processing equipment 100 is usually equipped with an automatic dispensing system 70. The automatic dispensing system 70 improves the automation of the garment processing equipment 100 by automatically dispensing garment processing agents. The automatic dispensing system 70 can automatically dispense different amounts of detergent and fabric softener according to different garment processing procedures, achieving more precise control and reducing the user's workload.

[0130] The self-dispensing system 70 includes a self-dispensing box 71 for storing laundry detergent. The self-dispensing box 71 is connected to the front end of the drying tunnel shell 31, making full use of the space between the drying tunnel shell 31 and the panel. This allows for better utilization of the internal space of the laundry treatment equipment 100, resulting in a more compact internal structure without affecting the layout of other internal components. Furthermore, the self-dispensing box 71 is positioned on the side facing the panel, facilitating direct user access to replenish the laundry detergent.

[0131] Furthermore, the self-dispensing box 71 can be provided with a corresponding number of storage chambers according to the number of second rollers 20. For example, when there are two second rollers 20, the self-dispensing box 71 has a first storage chamber and a second storage chamber that are isolated from each other, and two mixing chambers 72. Through the mixing function of the mixing chambers 72, the laundry detergent can be fully mixed with water to form a uniform mixture, thereby improving the washing effect.

[0132] Please continue reading. Figure 11In some embodiments, the self-dispensing system 70 further includes a self-dispensing pump 73 and a self-dispensing pump 73 connected to a self-dispensing box 71. The self-dispensing box 71 has a liquid storage chamber. The self-dispensing pump 73 has a liquid extraction end and a liquid outlet end. The liquid extraction end is connected to the liquid storage chamber. The mixing chamber 72 is connected to the self-dispensing pump 73 and the water inlet pipe of the laundry treatment device 100, and has a mixing chamber connected to the inside of the second drum 20. The liquid outlet end of the self-dispensing pump 73 is connected to the mixing chamber. The self-dispensing pump 73 is used to pump the laundry treatment agent in the self-dispensing box 71 into the mixing chamber. Understandably, the water transported by the water inlet pipe and the laundry treatment agent pumped from the self-dispensing box 71 will converge and be uniformly mixed in the mixing chamber to form a mixed liquid. The mixing chamber 72 is also provided with a liquid outlet, which is connected to the inside of the second drum 20 so that the mixed liquid flows into the second drum 20 for washing the clothes to be treated.

[0133] Specifically, the self-feeding box 71 is connected to the self-feeding pump 73 by a pipeline, and the self-feeding pump 73 is connected to the mixing chamber 72 and the mixing chamber 72 is connected to the second roller 20 by a pipeline. Since the pipeline can be bent freely, it can adapt to the complex spatial layout in the garment care equipment.

[0134] like Figure 11 In one configuration, along the vertical direction of the garment processing equipment 100, the mixing chamber 72 and the self-injecting pump 73 are both disposed between the first roller 10 and at least two second rollers 20. Whether the at least two second rollers 20 are above or below the first roller 10, the second rollers 20 are arranged in a cylindrical shape, and their vertical cross-section presents a circle. The cylindrical design of the second rollers 20 naturally forms four empty areas on both sides of its top and bottom, namely the upper left corner, lower left corner, upper right corner, and lower right corner. Specifically, when at least two second rollers 20 are below the first roller 10, the mixing chamber 72 and the self-injecting pump 73 can be placed in the upper left and upper right empty areas of the second rollers 20; if at least two second rollers 20 are above the first roller 10, the mixing chamber 72 and the self-injecting pump 73 can be placed in the lower left and lower right empty areas of the second rollers 20.

[0135] In another configuration, at least two second rollers 20 are located below the first roller 10, close to the base plate 61. In this case, the mixing chamber 72 and the self-starting pump 73 are installed in the space between the second rollers 20 and the base plate 61, utilizing the empty areas at the lower left and lower right corners of the second rollers 20.

[0136] In another configuration, the housing 63 also includes a top plate (not shown) disposed opposite to the base plate 61 in the vertical direction. When at least two second rollers 20 are disposed above the second roller 20, a gap area is also formed between the second roller 20 and the top plate, and the mixing chamber 72 and the self-starting pump 73 can be installed at the upper left and upper right corners of the second roller 20.

[0137] Furthermore, both the mixing chamber 72 and the self-injecting pump 73 are arranged close to the second drum 20, which can reduce the distance of the mixed liquid transportation, thereby improving the detergent dosing efficiency and speeding up the garment processing. This application does not limit the specific installation position of the mixing chamber 72 and the self-injecting pump 73, but its intention is to make full use of the empty areas formed by the upper left, lower left, upper right, and lower right corners of the second drum 20 to facilitate the installation and maintenance of the mixing chamber 72 and the self-injecting pump 73, while optimizing the overall layout and space utilization of the garment processing equipment 100.

[0138] Taking the example of having two second rollers 20, there are also two mixing chambers 72. The two mixing chambers 72 are arranged at intervals in the left and right direction. The two mixing chambers 72 are set in a one-to-one correspondence with the second rollers 20, that is, each mixing chamber 72 independently corresponds to one second roller 20 for conveying the mixed liquid.

[0139] Along the vertical direction, the projection of the mixing chamber 72 lies within the projection of the second roller 20, reducing the need for external space and improving the space utilization efficiency between the internal structures of the garment processing equipment 100. The compact layout of the mixing chamber 72 and the second roller 20 helps to reduce the floor space occupied by the garment processing equipment 100, making the overall structure more compact, which is especially important in environments with limited space.

[0140] Furthermore, the two mixing chambers 72 are symmetrically arranged in the left-right direction about the plane of symmetry, and the rotation axis of the first roller 10 is located within the plane of symmetry. The symmetrical arrangement of the mixing chambers 72 helps to balance the load of the garment processing equipment 100 and improve the stability and balance of the garment processing equipment 100 during operation.

[0141] Specifically, one mixing chamber 72 is located at the lower left corner of the second drum 20 on the left, and the other mixing chamber 72 is located at the lower right corner of the second drum 20 on the right. It can be seen that the self-priming pump 73, which works with the left mixing chamber 72, is located at the lower right corner of the left second drum 20, while the self-priming pump 73, which works with the right mixing chamber 72, is located at the lower left corner of the right second drum 20. Both mixing chambers 72 are positioned close to the inlet at the front of the second drum 20, effectively utilizing underutilized corner space within the washing equipment and making the overall design more compact. Furthermore, because the mixing chambers 72 and the self-priming pump 73 are relatively close, the required piping can be shorter, reducing piping complexity and potential leakage points. The mixing chamber 72 can also utilize the space between the second drum 20 and the panel, improving the efficiency of the internal space of the garment processing equipment 100. This space can also be used to appropriately enlarge the mixing chamber 72, making it suitable for washing large quantities of garments.

[0142] In some embodiments, the self-dispensing box 71 has two mutually isolated liquid storage chambers, each used to store a laundry treatment agent, such as one liquid storage chamber for storing detergent and the other for storing fabric softener. The number of self-dispensing pumps 73 is correspondingly set to two, with each pump 73 having its suction end connected to one liquid storage chamber and its discharge end connected to one mixing chamber, so that the two second drums 20 each contain different mixtures to meet the personalized washing needs of different users. For example, one second drum 20 performs ordinary washing, while the other second drum 20 performs fabric softening treatment.

[0143] like Figure 12 and Figure 13 As shown, in some embodiments, the second drum 20 includes an outer drum 22 and an inner drum 21 rotatably disposed within the outer drum 22. The outer drum 22 is supported on a base 64 and has a mounting space between it and the base 64. The outer drum 22 includes a main body 221 and a water-collecting protrusion 222 protruding from the outer wall of the main body 221. The main body 221 is cylindrical and houses the inner drum 21. The water-collecting protrusion 222 has a hot water tank communicating with the garment processing chamber of the inner drum 21, and a heater is provided in the hot water tank to heat the water. By heating the water through the heater in the hot water tank, hot water can be provided for washing the second drum 20, which helps to improve the stain removal ability, especially for stubborn stains, where hot water can more effectively help the detergent work. Furthermore, the heater in the water-collecting protrusion 222 allows users to adjust the water temperature according to different washing needs, thereby providing appropriate washing conditions for different types of garments and protecting the fabric.

[0144] Please see Figure 12 , Figure 13 and Figure 14 In some embodiments, the garment processing device 100 further includes a shock-absorbing device 80. In one configuration, the shock-absorbing device 80 is disposed on the base plate 61 and located between the second roller 20 and the base plate 61. A through hole may be provided on the base 64, through which the shock-absorbing device 80 passes and is connected to the second roller 20. In another configuration, the shock-absorbing device 80 is disposed on the base 64 and located between the second roller 20 and the base 64. The shock absorption device 80 specifically includes a shock absorption support 81, a first shock absorber 82, and a second shock absorber 83. The shock absorption support 81 is supported on the second roller 20. One end of the first shock absorber 82 is connected to the shock absorption support 81, and the other end is connected to the second shock absorber 83. The first shock absorber 82 is used to absorb vibration of the second roller 20 at least in the vertical direction, while the second shock absorber 83 is used to absorb vibration of the second roller 20 at least in the horizontal direction. The first shock absorber 82 and the second shock absorber 83 can effectively reduce the vibration generated by the second roller 20 during operation and reduce the noise generated by the clothing processing equipment 100 during operation.

[0145] Specifically, the outer cylinder 22 also includes support columns 223 extending toward the shock-absorbing support member 81. Multiple support columns 223 can be provided. For example, the multiple support columns 223 are divided into two groups. The two groups of support columns 223 are arranged at intervals along the depth direction of the second roller 20. Each group includes two support groups. The two support columns 223 are arranged at intervals along the left and right directions. All the multiple support columns 223 are supported on the shock-absorbing support member 81. Providing multiple support columns 223 can distribute the weight of the second roller 20 onto the shock-absorbing support member 81, reducing the pressure on a single point.

[0146] For example, the first damping element 82 includes an elastic damping ring and a guide post. The elastic damping ring is movably sleeved around the guide post. The elastic damping ring can provide better elastic deformation, thereby more effectively absorbing and reducing the vibration of the roller in the vertical direction. The guide post is used to guide the elastic damping ring to deform in the vertical direction, ensuring that the elastic damping ring deforms in the correct direction, thereby improving the accuracy and effect of damping.

[0147] The aforementioned elastic damping rings can be springs or elastic rubber rings, both of which have high elasticity and viscoelasticity. This means that they can produce large elastic deformation after being subjected to force, thereby absorbing impact and vibration.

[0148] Please continue reading. Figure 12 , Figure 13 and Figure 14 The second shock absorber 83 is connected to the base plate 61 or the base 64 and extends along the front and rear direction. The first shock absorber 82 is connected between the shock absorber support 81 and the second shock absorber 83. The first shock absorber 82 can effectively absorb and disperse the vibration generated by the second roller 20 during operation, and improve the stability of the entire garment processing equipment 100.

[0149] It should be noted that the shock-absorbing support 81 has a downward recessed relief recess 81a in the middle to avoid the water collection protrusion 222, so that the hot water tank can be installed in the relief recess 81a. Without increasing the overall floor area of ​​the clothing processing equipment 100, the internal space is effectively utilized, making the design of the clothing processing equipment 100 more compact.

[0150] Specifically, there are two second shock absorbers 83 arranged opposite each other in the left-right direction. This arrangement more evenly distributes the weight of the second roller 20, reducing pressure points on the base plate 61 or base 64, thereby improving the operational stability of the second roller 20. Furthermore, one of the self-starting pump 73 and the mixing chamber 72 corresponding to the second roller 20 is located at the front end of one second shock absorber 83, and the other is located at the front end of the other second shock absorber 83, fully utilizing the space between the front ends of the two second shock absorbers 83 and the panel.

[0151] Four first shock absorbers 82 are provided, symmetrically arranged on both sides of the second drum 20 about its central axis. Essentially, the four first shock absorbers 82 are divided into two groups, arranged in a left-right direction. Each group includes two first shock absorbers 82 connected to the second shock absorber 83 in a front-back direction. When the second drum 20 vibrates in the left-right direction during washing, these vibrations can be absorbed and canceled by the symmetrically arranged first shock absorbers 82. When the second drum 20 vibrates in the front-back direction, these vibrations can be canceled by the first shock absorbers 82 extending in the front-back direction of the second shock absorber 83.

[0152] The overall layout of the four primary damping components 82 not only absorbs vibrations in the left-right direction but also helps to disperse vibrations in the front-back direction. This multi-directional damping design improves the stability of the equipment in multiple dimensions.

[0153] like Figure 14As shown, further, the second damping component 83 includes a first damping section 831, two damping transition sections 832, and two second damping sections 833. The first damping section 831 is disposed on the base plate 61 or the base 64 and extends in the front-rear direction. The two damping transition sections 832 are respectively connected to the two ends of the first damping section 831 extending in the front-rear direction. The damping transition sections 832 and the first damping section 831 are arranged at an angle, that is, the first damping section 831 is inclined upward from the end connected to the first damping section 831. The two second damping sections 833... The second shock absorber 833 is connected to the end of the shock-absorbing support 81 opposite to the first shock absorber 831. The second shock absorber 833 is spaced apart from and roughly parallel to the base plate 61. The first shock absorber 82 is connected to the second shock absorber 833. Understandably, the design of the second shock absorber 83 is somewhat similar to a seesaw structure. When the second drum 20 generates unbalanced forces during the washing process, it is not only a movement in the front-back direction, but also usually includes a certain degree of swaying in the up-down direction. These forces are transmitted to the second shock absorber 83 through the first shock absorber 82. The seesaw-like design of the second shock absorber 83 can disperse these forces along the front-back and up-down directions, thereby reducing the impact on a single point and improving the stability of the garment processing equipment 100 during the garment processing process.

[0154] 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.
