Description

Technical Field

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

[0002] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0003] Clothing handling appliances (washing machines, dryers, washer-dryer combos, etc.) have greatly reduced people's housework burden. With the improvement of living standards, users' functional demands are increasing, especially the demand for separate washing functions. For example, there is a significant increase in the need to wash different categories of clothing such as adult outerwear, infant clothing, and underwear separately to avoid cross-contamination and meet differentiated washing requirements (such as sterilization and gentle care). However, traditional single-tub washing machines, due to their single washing space, cannot achieve physical isolation or simultaneous processing of multiple types of clothing, forcing users to wash in batches. This reduces efficiency and increases water and electricity consumption, thus limiting the functionality of single-tub washing machines.

[0004] Multi-drum washing machines allow users more flexibility in selecting the drums they need for washing, enabling them to separate different types of clothing for washing. However, current multi-drum washing machines require a heat pump module for each drum to dry the clothes inside, which increases the manufacturing cost of multi-drum washing machines. Utility Model Content

[0005] This application discloses a clothing processing device that has a drying function, which can dry the clothes in each drum while reducing the manufacturing cost of the clothing processing device.

[0006] To achieve the above objectives, this application discloses a garment processing device, comprising: a housing, wherein the housing is provided with:

[0007] Multiple rollers are arranged at intervals between each other, and each roller has a garment processing chamber.

[0008] Drying air duct, including:

[0009] Main air duct;

[0010] Multiple circulating branch air ducts are connected between the main air duct and each of the rollers. The garment processing chamber of each roller is connected to the main air duct through one of the circulating branch air ducts to form a circulating air path.

[0011] A damper assembly is disposed in the plurality of circulating branch air ducts, and the damper assembly is configured to control the opening and closing of the plurality of circulating branch air ducts with the main air duct respectively;

[0012] The first fan is installed in the main air duct so that the drying air in the drying air duct flows in a preset direction;

[0013] Heat pump systems include:

[0014] A compressor is used to compress refrigerant;

[0015] Multiple condensers are respectively located in the multiple circulating branch air ducts, and the refrigerant inlet of each condenser is connected to the refrigerant outlet of the compressor;

[0016] Multiple evaporators are respectively located in the multiple circulating branch air ducts along the preset air direction. The evaporators are located downstream of the clothing processing chamber, and the condenser is located downstream of the evaporators and upstream of the clothing processing chamber. The refrigerant inlet of each evaporator is connected to the refrigerant outlet of the condenser in the same circulating branch air duct, and the refrigerant outlet of each evaporator is connected to the refrigerant inlet of the compressor.

[0017] Thus, the first fan is located in the main air duct (e.g. Figure 5 As shown, the main air duct can be Figure 5Within the area highlighted by the dashed line, multiple evaporators are located in multiple circulating branch air ducts along a preset airflow direction. The condenser is located downstream of the evaporators and upstream of the clothing processing chamber. When the fan operates, causing the drying air to flow along the preset airflow direction, the humid gas in the clothing processing chamber enters the circulating branch air ducts. Upon entering the circulating branch air ducts, the humid gas comes into contact with the evaporators, where its temperature drops and water droplets precipitate, becoming dry, low-temperature gas. This dry, low-temperature gas continues to flow into the main air duct, where its temperature rises under the action of the condenser, becoming dry, high-temperature gas. This dry, high-temperature gas then re-enters the clothing processing chamber from the circulating branch air ducts, contacting the humid clothing and removing moisture from the clothes, thus drying them. It is worth noting that in this embodiment, the heat pump module is not only equipped with a single compressor to dry the clothes in the clothes processing chambers of each roller. In this embodiment, multiple circulating branch air ducts are connected to the main air duct to form a damper assembly. Furthermore, an evaporator is installed in the condenser and clothes processing chamber of each circulating branch air duct, so that each clothes processing chamber has a corresponding evaporator. If one evaporator fails, causing the drying function of its corresponding roller to fail, the other evaporators can work normally, and the other rollers can dry the clothes in the clothes processing chamber normally.

[0018] As an optional implementation, the drum has a drying air inlet and a drying air outlet communicating with the garment processing chamber;

[0019] Each of the aforementioned circulating branch air ducts includes:

[0020] An air inlet branch duct, the inlet of which is connected to the outlet of the main air duct, and the outlet of which is connected to the drying air inlet of the corresponding drum, and multiple condensers are respectively arranged in each of the air inlet branch ducts;

[0021] The air outlet branch duct is connected to the drying air outlet of the drum, and the outlet of the air outlet branch duct is connected to the inlet of the main air duct. The multiple evaporators are respectively arranged in each of the air outlet branch ducts.

[0022] The damper assembly includes:

[0023] Multiple air inlet dampers are respectively installed in the air inlet branch ducts of each of the circulating branch ducts to control the connection and disconnection between the main duct and each of the air inlet branch ducts;

[0024] Multiple air outlet dampers are respectively installed in the air outlet branch ducts of each of the circulating branch ducts to control the connection and disconnection between the main duct and each of the air inlet branch ducts.

[0025] Thus, the drying air inlet of the drum can be located at the front opening of the drum, and the drying air outlet can be located at the rear side of the drum, allowing the drying air to flow from the front to the rear of the drum, covering the entire garment processing chamber of the drum, maximizing the utilization of the drying air and effectively drying the clothes in the garment processing chamber. Each circulating branch air duct includes an inlet branch air duct and an outlet branch air duct. The inlet branch air duct guides the drying air in the main air duct from the drying air inlet into the garment processing chamber, and the outlet branch air duct guides the air in the garment processing chamber into the main air duct. It is worth noting that each evaporator is located in the outlet branch air duct and each evaporator is located in the inlet branch air duct, so that the evaporators are downstream of the garment processing chamber, and the condenser is located downstream of the evaporators and upstream of the garment processing chamber. This allows the evaporators to dry the humid air entering the outlet branch air duct from the garment processing chamber, and the condenser to heat the air in the inlet branch air duct (i.e., the air preparing to enter the garment processing chamber).

[0026] As an optional implementation, the garment handling device further includes:

[0027] Multiple second fans are respectively installed in the multiple circulating branch air ducts.

[0028] In this way, the drying air in the circulating branch duct can be accelerated by the second fan, thereby increasing the flow rate of the drying air and improving the drying efficiency of the heat pump module. Moreover, when the first fan fails, each circulating branch duct still has a second fan to provide power for the drying air, which can provide fault tolerance for the heat pump module.

[0029] As an optional implementation, along the preset wind direction, the second fan in the circulating branch air duct is located downstream of the condenser and upstream of the clothing processing chamber.

[0030] By placing the second fan downstream of the condenser and upstream of the clothing processing chamber, the second fan can be located in the air inlet branch duct, allowing the airflow from the air inlet branch duct to enter the clothing processing chamber more quickly, thereby drying the clothes inside the clothing processing chamber and improving the drying efficiency of the heat pump module.

[0031] As an optional implementation, the heat pump system further includes:

[0032] Multiple refrigerant switching valves are respectively located at the refrigerant inlet of the multiple condensers to control the on / off state of the compressor and each of the condensers.

[0033] In this way, the refrigerant switching valve can control the flow of refrigerant. When working in the circulating air path formed by any circulating branch air duct and the main air duct, when drying clothes, the refrigerant switching valve can control the connection between the refrigerant inlet of the condenser and the refrigerant outlet of the compressor in the corresponding circulating air path, so that the compressor, condenser, throttle valve and the corresponding evaporator can be connected in series. The refrigerant discharged by the compressor can form a smooth circulation, so that the condenser can heat the drying air and the evaporator can cool the drying air and remove the moisture in the drying air.

[0034] As an optional implementation, the garment processing device further includes a first electric heater disposed within the main air duct.

[0035] Thus, when heating the drying air, it can be done solely through a condenser, or a first electric heater can be added to provide secondary heating for the drying air, further increasing the temperature of the drying duct and improving the efficiency of drying clothes. The first electric heater can be a resistance wire that generates heat when current is applied, thus heating the drying air. The first electric heater can be installed in the main air duct. By heating the drying air in the main air duct with the first electric heater, the secondary-heated drying air can enter any circulating branch air duct, eliminating the need to add a first electric heater in every circulating branch air duct and reducing the production cost of the clothing processing device.

[0036] As an optional implementation, the garment handling device further includes:

[0037] Multiple second electric heaters are provided, each of which is located in the air inlet duct of the circulating branch duct.

[0038] In this way, a second electric heater is installed in each air inlet branch duct. The drying air in the air inlet branch duct is closer to the clothing processing chamber. The second electric heater reheats the drying air in the air inlet branch duct, which can raise the temperature of the drying air about to enter the clothing processing chamber. When the path of the air inlet branch duct is long and the drying air has a certain amount of heat loss, the second electric heater can quickly raise the temperature of the drying air to ensure that the temperature of the drying air entering the clothing processing chamber meets the requirements and ensures the drying efficiency of the heat pump module.

[0039] As an optional implementation, each of the second electric heaters is located upstream of the clothing processing chamber and downstream of the second fan, along the preset airflow direction.

[0040] In this way, the second electric heater can be located in the air inlet branch duct. This position allows the second electric heater to be located between the clothing processing chamber and the second fan. The gas in the air inlet branch duct first enters the second fan and then comes into contact with the second electric heater, where it is heated a second time. This avoids the gas entering the second fan being too hot, which would affect the service life of the second fan.

[0041] As an optional implementation, the garment handling device further includes:

[0042] Multiple filters are respectively installed at the inlet of the outlet branch duct of each of the circulating branch ducts.

[0043] In this way, the filter can filter out impurities such as fibers from the clothes. By installing the filter at the inlet of the air outlet branch duct, it can prevent impurities from entering the air outlet branch duct and the main air duct from the clothes processing chamber, thus preventing impurities from damaging the evaporator, clogging the fan, reducing the air volume, and reducing the drying effect.

[0044] As an optional implementation, the housing includes:

[0045] The front panel is provided with a first garment inlet, a second garment inlet, and a third garment inlet;

[0046] The plurality of said rollers include:

[0047] The first roller, the opening of the first roller is opposite to the first clothes inlet;

[0048] The second roller, the opening of which is opposite to the second garment inlet;

[0049] The third roller, the opening of which is opposite to the third garment inlet;

[0050] The front panel is a one-piece structure.

[0051] Therefore, the garment handling device disclosed in this application can be either a separate multi-drum washer-dryer or an integrated multi-drum washer-dryer. In a separate multi-drum washer-dryer, the housing comprises multiple units, and each unit can house one or more drums, for example, combined with... Figure 2 and Figure 3 When the garment handling unit is a three-drum washer-dryer combo, the lower first drum is housed within a single compartment, while the upper first and second drums are housed either within a single compartment or in two separate compartments. Figure 1 As shown, when the garment handling device is an integrated three-drum washer-dryer, the first drum, the second drum, and the third drum are all housed in the same compartment.

[0052] Integrated multi-drum washer-dryer combos utilize space more efficiently, eliminating the need to reserve extra space for multiple independent drums. They are better suited for small apartments or compact home layouts, and their overall appearance is more unified and harmonious, reducing any sense of disharmony with home décor. At the same time, the integrated design usually integrates the water and electricity systems and control systems of each drum into a single unit, eliminating the need to connect multiple sets of water and electricity interfaces during installation, making operation simpler. In addition, the integrated control logic allows for smoother coordinated operation between multiple drums, such as the ability to simultaneously set washing programs for different drums, resulting in greater ease of use.

[0053] Compared with the prior art, the beneficial effects of this application are:

[0054] The clothing processing device provided in this application includes a heat pump system comprising a compressor, a condenser, and multiple evaporators. The condenser is located in the main air duct, and each evaporator is located in one of the multiple circulating branch air ducts. The refrigerant in the heat pump system, after being compressed by the compressor, enters the condenser, where it liquefies. The liquefied refrigerant then enters each evaporator, where it vaporizes, thereby condensing the hot, humid air discharged from each drum and flowing through the evaporator. Because the heat pump system can control the refrigerant temperature, the temperature fluctuation of the refrigerant with changes in ambient temperature is relatively small. This ensures that the evaporator maintains a large temperature difference with the hot, humid air in different seasons and at different times, guaranteeing the condensation effect of the hot, humid air. Since the heat pump system of this application uses only one compressor, with multiple evaporators and multiple condensers sharing one compressor, compared to embodiments where each evaporator and condenser has its own compressor, this embodiment reduces the number of compressors, thereby reducing the production cost of the clothing processing device, saving space within the casing, and reducing the weight and volume of the clothing processing device. Furthermore, each roller's garment processing chamber is connected to the main air duct via a circulating branch duct to form a circulating air path. An evaporator and condenser are installed in each circulating branch duct, allowing the drying air ducts and drying circuits of each roller and heat pump module to be independent systems. If the evaporator or condenser in one circulating branch duct fails, affecting the drying function of its corresponding garment processing chamber, the drying function of other garment processing chambers remains unaffected and can still dry clothes normally. Moreover, the first fan is located in the main air duct. Regardless of which circulating branch duct is connected to the main air duct, the first fan can provide power for the drying air, eliminating the need for a fan for each circulating branch duct and further reducing the production cost of the garment processing device.

Detailed Implementation

[0066] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0067] In this application, the terms "upper," "lower," "front," "top," "bottom," "inner," "outer," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0068] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0069] Furthermore, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0070] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0071] Clothing handling appliances (washing machines, dryers, washer-dryer combos, etc.) have greatly reduced people's housework burden. With the improvement of living standards, users' functional demands are increasing, especially the demand for separate washing functions. For example, there is a significant increase in the need to wash different categories of clothing such as adult outerwear, infant clothing, and underwear separately to avoid cross-contamination and meet differentiated washing requirements (such as sterilization and gentle care). However, traditional single-tub washing machines, due to their single washing space, cannot achieve physical isolation or simultaneous processing of multiple types of clothing, forcing users to wash in batches. This reduces efficiency and increases water and electricity consumption, thus limiting the functionality of single-tub washing machines.

[0072] Multi-drum washing machines allow users more flexibility in selecting the drums they need for washing, enabling them to separate different types of clothing for washing. Furthermore, each drum can be equipped with a heat pump module to dry the clothes inside each drum.

[0073] However, the inventors discovered that current multi-drum washing machines are equipped with an independent heat pump module for each drum. The evaporator of each heat pump module condenses the humid and hot air in each air duct. Each heat pump module has a compressor. In other words, current multi-drum washing machines have multiple compressors. Since the manufacturing cost of compressors is high, using multiple compressors will lead to a higher manufacturing cost for multi-drum washing machines.

[0074] Based on this, this application discloses a clothing processing device that has a drying function, which can dry the clothes in each drum while reducing the manufacturing cost of the clothing processing device.

[0075] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0076] Please see Figure 1 and Figure 4 , Figure 1 This is a schematic diagram of the structure of the clothing processing device 100 disclosed in the embodiments of this application. Figure 4This is a schematic diagram of the airflow path and refrigerant flow path of the clothing processing device 100 (two rollers 2) disclosed in this application embodiment. This application embodiment discloses a clothing processing device 100, including a housing 1. The housing 1 contains multiple rollers 2, a drying air duct 3, a fan, and a heat pump module 5. The rollers 2 are spaced apart from each other, and each roller 2 has a clothing processing chamber. The drying air duct 3 includes a main air duct 31, multiple circulating branch air ducts 32, and a damper assembly 33. The multiple circulating branch air ducts 32 connect the main air duct 31 to each roller 2. The clothing processing chamber of each roller 2 is connected to the main air duct 31 through a circulating branch air duct 32 to form a circulating air path. The damper assembly 33 is located in the multiple circulating branch air ducts 32 and is configured to control the opening and closing of the multiple circulating branch air ducts 32 with the main air duct 31. The fan is located inside the main air duct 31. The drying air in the drying duct 3 flows along a preset airflow direction. The heat pump module 5 includes a compressor 51, multiple condensers 52, and multiple evaporators 53. The compressor 51 is used to compress refrigerant. Each condenser 52 is located in a multiple circulating branch duct 32, and the refrigerant inlet of each condenser 52 is connected to the refrigerant outlet of the compressor 51. The multiple evaporators 53 are located in multiple circulating branch ducts 32 along a preset airflow direction. The evaporators 53 are located downstream of the clothing processing chamber, and the condensers 52 are located downstream of the evaporators 53 and upstream of the clothing processing chamber. The refrigerant inlet of each evaporator 53 is connected to the refrigerant outlet of the condenser 52 in the same circulating branch duct 32, and the refrigerant outlet of each evaporator 53 is connected to the refrigerant inlet of the compressor 51.

[0077] The garment handling device 100 includes multiple rollers 2, all housed within the housing 1. It can simultaneously handle different types, colors, or degrees of soiling of garments, enabling zoned washing without the need for sequential washing, thus saving time and improving cleaning efficiency.

[0078] In some embodiments, the clothes handling device 100 may have an outer drum adapted to the drum 2. The outer drum is connected inside the housing 1. The outer drum is mainly used to contain washing water and support the drum 2. It is also a key component for draining and holding water in the clothes handling device 100, and can withstand the pressure of the water during washing and the force generated when the drum 2 rotates. The drum 2 is disposed inside the outer drum and can rotate relative to the outer drum. The drum 2 has a clothes handling chamber for containing clothes. The drum 2 is the component that directly carries the clothes for washing, rinsing and dehydration. Through the centrifugal force and friction generated by rotation, the clothes tumble and rub in the washing liquid to achieve the purpose of cleaning the clothes. It can be understood that since both the outer drum and the inner drum are cylindrical structures, for a drum 2 washing machine with a multi-drum structure, the openings of the inner drum and the outer drum face forward. The bottom wall of the inner drum is the rear wall of the inner drum, and the bottom wall of the outer drum is the rear wall of the outer drum.

[0079] Combination Figure 4In some embodiments, the heat pump system has only one compressor 51, and multiple evaporators 53 share one compressor 51. Compared with embodiments in which each evaporator 53 is equipped with a separate compressor 51, this embodiment can reduce the number of compressors 51, thereby reducing the production cost of the clothing processing device 100, saving space in the housing 1, and reducing the weight and volume of the clothing processing device 100.

[0080] Combination Figure 4 In some embodiments, after the refrigerant is discharged from the refrigerant outlet of the compressor 51, it can enter the refrigerant inlet of the condenser 52 through the refrigerant pipeline, and then enter the condenser 52. In the condenser 52, heat is released, allowing the condenser 52 to heat the surrounding air. The air, heated by the condenser 52, then enters the clothes processing chamber to dry the clothes. Afterward, the refrigerant is discharged from the refrigerant outlet of the condenser 52 and enters the expansion valve 55. Under the action of the expansion valve 55, the refrigerant pressure is reduced, and then it enters the refrigerant inlet of the evaporator 53. In the evaporator 53, the refrigerant absorbs heat, allowing the evaporator 53 to cool the surrounding air. The humid, hot air discharged from the clothes processing chamber cools down under the action of the evaporator 53, causing moisture to precipitate and form water droplets. A drainage structure can be installed at the corresponding position of the evaporator 53 to collect and discharge the water droplets. Finally, the refrigerant is discharged from the refrigerant outlet of the evaporator 53 and re-enters the compressor 51 from the refrigerant inlet.

[0081] Combination Figure 4 In some embodiments, the first fan 41 is located in the main air duct 31 (e.g., Figure 5 As shown, the main air duct 31 can be Figure 5 Within the area highlighted by the dashed line, multiple evaporators 53 are respectively located within multiple circulating branch air ducts 32. Along a preset airflow direction, the condenser 52 is located downstream of the evaporators 53 and upstream of the clothing processing chamber. During the operation of the fan, which causes the drying air to flow along the preset airflow direction, the humid gas in the clothing processing chamber enters the circulating branch air duct 32. After entering the circulating branch air duct 32, the humid gas comes into contact with the evaporators 53, causing its temperature to drop and water droplets to precipitate, becoming dry, low-temperature gas. This dry, low-temperature gas continues to flow into the main air duct 31. Under the action of the condenser 52 in the main air duct 31, its temperature rises, becoming dry, high-temperature gas. This dry, high-temperature gas then re-enters the clothing processing chamber from the circulating branch air duct 32, coming into contact with the humid clothing and removing moisture from the clothing, thus drying it.

[0082] It is worth noting that in this embodiment, it is not only by setting up a compressor 51 that the heat pump module 5 can dry the clothes in the clothes processing chamber of each roller 2. In this embodiment, multiple circulating branch air ducts 32 and the main air duct 31 form an air damper assembly 33. Furthermore, an evaporator 53 is set in the condenser 52 of each circulating branch air duct 32 and in the clothes processing chamber, so that each clothes processing chamber has a corresponding evaporator 53. If one evaporator 53 is damaged, causing the drying function of its corresponding roller 2 to fail, the other evaporators 53 can work normally, and the other rollers 2 can dry the clothes in the clothes processing chamber normally.

[0083] It is worth noting that the number of rollers 2 can be one, two, or three, as shown in the structure. Figure 8 As shown, Figure 8 This is a schematic diagram of the airflow path and refrigerant flow path of the garment handling device 100 (three rollers 2) disclosed in this application embodiment. The number of rollers 2 can also be greater, which will not be elaborated here. When multiple rollers 2 are provided, there are also multiple circulating branch air ducts 32, and connecting air ducts can be added between the multiple circulating branch air ducts 32 and the main air duct 31 for connection.

[0084] It is worth noting that the first fan 41 is installed in the main air duct 31. Regardless of which circulating branch air duct 32 is connected to the main air duct 31, the first fan 41 can provide power for the drying air. The entire garment processing device 100 only needs one first fan 41 to provide power for the drying air in the circulating air path, which can further reduce the production cost of the garment processing device 100.

[0085] According to the clothing processing device 100 of this utility model embodiment, the heat pump system of the clothing processing device 100 includes a compressor 51, a condenser 52 and multiple evaporators 53. The condenser 52 is disposed in the main air duct 31, and each evaporator 53 is disposed in multiple circulating branch air ducts 32. The refrigerant in the heat pump system can enter the condenser 52 after being compressed by the compressor 51. The condenser 52 can liquefy the refrigerant, and the liquefied refrigerant can enter each evaporator 53. The evaporator 53 can vaporize the refrigerant, thereby condensing the hot and humid air that flows through the evaporator 53 after being discharged from each roller 2. Since the heat pump system can control the temperature of the refrigerant, the temperature of the refrigerant fluctuates less with changes in ambient temperature. This can ensure that the evaporator 53 has a large temperature difference with the hot and humid air in different seasons and at different times, so as to ensure the condensation effect of the hot and humid air. Since the heat pump system of this application has only one compressor 51, and multiple evaporators 53 and multiple condensers 52 share one compressor 51, compared with the embodiment where each evaporator 53 and condenser 52 is equipped with a separate compressor 51, this embodiment can reduce the number of compressors 51, thereby reducing the cost of the clothing processing device 100, saving space in the housing 1, and reducing the weight and volume of the clothing processing device 100. Furthermore, the clothing processing chamber of each roller 2 is connected to the main air duct 31 through a circulating branch air duct 32 to form a circulating air path. An evaporator 53 and a condenser 52 are installed in each circulating branch air duct 32, so that the drying air duct 3 of each roller 2 and the drying circuit of the heat pump module 5 are independent systems. If the evaporator 53 or condenser 52 in one circulating branch air duct 32 is damaged, affecting the drying function of its corresponding clothing processing chamber, the drying function of other clothing processing chambers can remain unaffected and can still dry clothes normally. Moreover, since the first fan 41 is installed in the main air duct 31, the first fan 41 can provide power for the drying air regardless of which circulating branch air duct 32 is connected to the main air duct 31. It is not necessary to install a fan for each circulating branch air duct 32, which can further reduce the production cost of the garment processing device 100.

[0086] Combination Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the airflow path and refrigerant flow path of the clothing handling device 100 (two rollers 22) disclosed in this application embodiment, showing the airflow path to one roller 22. Figure 7This is a schematic diagram of the airflow path and refrigerant flow path of the clothing handling device 100 (two rollers 2) disclosed in this application embodiment. In some embodiments, the roller 2 has a drying air inlet 201 and a drying air outlet 202 communicating with the clothing handling chamber; each circulating branch air duct 32 includes an inlet branch air duct 321 and an outlet branch air duct 322. The inlet of the inlet branch air duct 321 is connected to the outlet of the main air duct 31, and the outlet of the inlet branch air duct 321 is connected to the drying air inlet 201 of the corresponding roller 2. Multiple condensers 52 are respectively disposed in each inlet branch air duct 321; the inlet of the outlet branch air duct 322 is connected to the drying air outlet 202 of the roller 2, and the outlet branch air duct... The outlet of 322 is connected to the inlet of the main air duct 31, and multiple evaporators 53 are respectively installed in each outlet branch air duct 322; the damper assembly 33 includes multiple inlet dampers 331 and multiple outlet dampers 332. The multiple inlet dampers 331 are respectively installed in the inlet branch air duct 321 of each circulation branch air duct 32 to control the connection and disconnection between the main air duct 31 and each inlet branch air duct 321; the multiple outlet dampers 332 are respectively installed in the outlet branch air duct 322 of each circulation branch air duct 32 to control the connection and disconnection between the main air duct 31 and each inlet branch air duct 321.

[0087] Specifically, the drying air inlet 201 of the drum 2 can be located at the front opening of the drum 2, and the drying air outlet of the drum 2 can be located at the rear side of the drum 2, so that the drying air can flow from the front side to the rear side of the drum 2, covering the entire garment processing chamber of the drum 2, maximizing the utilization of the drying air, and effectively drying the clothes in the garment processing chamber. Each circulating branch air duct 32 includes an inlet branch air duct 321 and an outlet branch air duct 322. The inlet branch air duct 321 can guide the drying air in the main air duct 31 from the drying air inlet 201 into the garment processing chamber, and the outlet branch air duct 322 can guide the air in the garment processing chamber into the main air duct 31. It is worth noting that each evaporator 53 is located in the outlet branch duct 322 and the inlet branch duct 321, so that the evaporator 53 is located downstream of the clothing processing chamber and the condenser 52 is located downstream of the evaporator 53 and upstream of the clothing processing chamber. This allows the evaporator 53 to dry the humid air entering the outlet branch duct 322 from the clothing processing chamber and the condenser 52 to heat the air in the inlet branch duct 321 (i.e., the air that is about to enter the clothing processing chamber).

[0088] Combination Figure 4 In some embodiments, the clothing handling device 100 further includes a plurality of second fans 42, which are respectively disposed in a plurality of circulating branch air ducts 32.

[0089] Specifically, the second fan 42 can accelerate the drying air in the circulating branch air duct 32, increase the flow rate of the drying air, thereby improving the drying efficiency of the heat pump module 5. Moreover, when the first fan 41 fails, each circulating branch air duct 32 still has the second fan 42 to provide power for the drying air, which can provide fault tolerance for the heat pump module 5.

[0090] Combination Figure 4 In some embodiments, along a preset wind direction, the second fan 42 in the circulating branch air duct 32 is located downstream of the condenser 52 and upstream of the clothing processing chamber.

[0091] Specifically, the second fan 42 can be located at any position in the circulating branch air duct 32. Setting the second fan 42 downstream of the condenser 52 and upstream of the clothes processing chamber allows the second fan 42 to be located in the air inlet branch air duct 321, which allows the airflow in the air inlet branch air duct 321 to enter the clothes processing chamber more quickly, thereby drying the clothes in the clothes processing chamber and improving the drying efficiency of the heat pump module 5.

[0092] Combination Figure 4 In some embodiments, the heat pump system also includes multiple refrigerant switching valves 54, which are respectively located at the refrigerant inlets of multiple condensers 52 to control the on / off state of the compressor 51 and each condenser 52.

[0093] Specifically, the refrigerant switching valve 54 can control the on / off of the refrigerant. When working in the circulating air path formed by any circulating branch air duct 32 and the main air duct 31 to dry clothes, the refrigerant switching valve 54 can control the refrigerant inlet of the condenser 52 in the corresponding circulating air path to connect with the refrigerant outlet of the compressor 51, so that the compressor 51, condenser 52, throttle valve 55 and the corresponding evaporator 53 can be connected in series. The refrigerant discharged by the compressor 51 can form a smooth circulation, so that the condenser 52 can heat the drying air and the evaporator 53 can cool the drying air and remove the moisture in the drying air.

[0094] Combination Figure 4 In some embodiments, the garment processing device further includes a first electric heater 6, which is disposed within the main air duct 31.

[0095] Specifically, when heating the drying air, it can be done solely through the condenser 52, or a first electric heater 6 can be added to provide secondary heating for the drying air, further increasing the temperature of the drying duct 3 and improving the efficiency of drying clothes. The first electric heater 6 can be a resistance wire that generates heat when current is applied, thus heating the drying air. The first electric heater 6 can be installed inside the main air duct 31. By heating the drying air in the main air duct 31 with the first electric heater 6, the secondary-heated drying air can enter any circulating branch air duct 32, thus eliminating the need to add a first electric heater 6 in every circulating branch air duct 32, thereby reducing the production cost of the clothes processing device 100.

[0096] Combination Figure 4 In some embodiments, the clothing handling device 100 further includes a plurality of second electric heaters 7, each of which is disposed in the air inlet branch duct 321 of the circulating branch duct 32.

[0097] Specifically, a second electric heater 7 can be installed in each air inlet branch duct 321. The drying air in the air inlet branch duct 321 is closer to the clothing processing chamber. The second electric heater 7 can reheat the drying air in the air inlet branch duct 321, which can raise the temperature of the drying air about to enter the clothing processing chamber. When the path of the air inlet branch duct 321 is long and the drying air has a certain heat loss, the second electric heater 7 can quickly increase the temperature of the drying air to ensure that the temperature of the drying air entering the clothing processing chamber meets the requirements and ensures the drying efficiency of the heat pump module 5.

[0098] Combination Figure 4 In some embodiments, each of the second electric heaters 7 is located upstream of the clothing processing chamber and downstream of the second fan 42 along a preset airflow direction.

[0099] Specifically, the second electric heater 7 can be installed at various locations in the air inlet branch duct 321, or it can be located upstream of the clothing processing chamber and downstream of the condenser 52. The second electric heater 7 can be located in the air inlet branch duct 321. This position allows the second electric heater 7 to be located between the clothing processing chamber and the second fan 42. The gas in the air inlet branch duct 321 first enters the second fan 42 and then comes into contact with the second electric heater 7, where it is heated a second time. This avoids the gas temperature entering the second fan 42 being too high, which would affect the service life of the second fan 42.

[0100] Combination Figure 4 In some embodiments, the clothing handling device 100 further includes a plurality of filters 8, which are respectively disposed at the inlet of the outlet branch air duct 322 of each circulating branch air duct 32.

[0101] Specifically, the filter 8 can be omitted, installed only at the inlet of the main air duct 31, or multiple filters 8 can be installed at the inlets of each branch air duct 322. The filter 8 can filter fibers and other impurities from clothing. Installing the filter 8 at the inlet of the branch air duct 322 prevents impurities from entering the branch air duct 322 and the main air duct 31 from the clothing processing chamber, thus preventing impurities from damaging the evaporator 53, clogging the fan, reducing airflow, and decreasing drying efficiency.

[0102] Combination Figures 1 to 3 , Figure 2 This is a schematic diagram of the first structure of the garment handling device 100 disclosed in the embodiments of this application, which is a split-type three-tub washer-dryer combo. Figure 3 This is a schematic diagram of a second structure of the garment handling device 100 disclosed in this application, which is a split-type three-drum washer-dryer. In some embodiments, the housing 1 includes a front panel 11, which has a first loading port 11a, a second loading port 11b, and a third loading port 11c; the plurality of drums 2 include a first drum 21, a second drum 22, and a third drum 23, with the opening of the first drum 21 facing the first loading port 11a; the opening of the second drum 22 facing the second loading port 11b; and the opening of the third drum 23 facing the third loading port 11c; the front panel 11 is an integral structure.

[0103] Specifically, the garment handling device 100 disclosed in this application can be a separate multi-drum washer-dryer or an integrated multi-drum washer-dryer. In the separate multi-drum washer-dryer, the housing 1 comprises multiple units, and each housing 1 can house one or more drums 2, for example, combined with... Figure 2 and Figure 3 When the garment handling device 100 is a split-type three-drum washer-dryer, the lower first drum 21 is installed in one housing 1, and the upper first drum 21 and second drum 22 are installed in one housing 1 or in two housings 1 respectively; for example Figure 1 As shown, when the garment handling device 100 is an integrated three-drum washer-dryer, the first drum 21, the second drum 22 and the third drum 23 are all installed in the same housing 1.

[0104] Integrated multi-drum washer-dryer combos utilize space more efficiently, eliminating the need to reserve extra space for multiple independent drums. This makes them more suitable for small apartments or compact home layouts, and their overall appearance is more unified and harmonious, reducing any sense of disharmony with home décor. At the same time, the integrated design typically integrates the water and electricity systems and control systems of each drum into a single unit, eliminating the need to connect multiple sets of water and electricity interfaces during installation, making operation simpler. In addition, the integrated control logic allows for smoother collaborative operation between multiple drums, such as the ability to simultaneously set washing programs for different drums, resulting in greater ease of use.

[0105] In addition, Figures 4 to 8 In the diagram, when refrigerant lines intersect with air ducts, the refrigerant lines are indicated by dashed lines, indicating that the refrigerant lines are not connected to the air ducts at that point, but simply cross over them.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
