[0002] A washer-dryer is a household appliance that combines the functions of a washing machine and a dryer. It washes and dries clothes in one device, eliminating the need to transfer clothes from the washer to the dryer.

[0003] In the existing technology, condensing washer-dryers use electric heaters for heating. The fan heats the air through the electric heater and blows it into the drum, taking away the moisture in the clothes to form wet air. The air is then cooled and dehydrated through the condenser, and then converted into dry air and continues to return to the entire drying system.

[0004] However, existing washer-dryers have the problem of poor performance. Utility Model Content

The weight detection component is used to monitor the weight of the clothes in real time, and the control component dynamically adjusts the working status of the refrigeration device and the liquid supply component. When the weight detection component detects that the weight of the clothes is low, the control component controls the refrigeration device to condense the airflow in the circulating air duct and stops the use of the liquid supply component, thereby reducing unnecessary energy consumption and avoiding the waste problem caused by excessive use of condensed water from the liquid supply component in traditional washer-dryers.

[0016] The embodiment of the present application provides a washer-dryer, which includes a housing, a drum, a circulating air duct, a liquid supply unit, a refrigeration device, a drying component, a weight detection unit, and a control unit.

[0017] The box body has a accommodating cavity.

[0018] The cylinder is located in the accommodating cavity and has a cavity.

[0019] A circulating air duct is provided between the outer periphery of the cylinder and the inner periphery of the box body, the circulating air duct is communicated with the cavity, and has a liquid inlet.

[0020] The liquid supply component has a liquid supply cavity which is communicated with the liquid inlet.

[0021] The refrigeration end of the refrigeration device is located in the circulating air duct. The refrigeration device is used to condense the air flow entering the circulating air duct through the cylinder.

[0022] The drying component is located in the circulating air duct and is used to heat the air flow in the circulating air duct.

[0023] The weight detection part is used to detect the weight of the cylinder.

[0024] The weight detection component, the refrigeration device, and the liquid supply component are all electrically connected to the control component. The control component is configured to control the refrigeration device and the liquid supply component to operate according to the detection result of the weight detection component, so as to condense the air flow in the circulating air duct.

[0025] The above technical solution has the following advantages or beneficial effects: The washer-dryer provided in the embodiment of the present application is provided with a refrigeration device, a liquid supply component, a weight detection component and a control component. The refrigeration device is used to condense the airflow carrying moisture in the circulating air duct. The liquid supply component is used to provide liquid, such as water, to the circulating air duct to condense the airflow carrying moisture in the circulating air duct. The weight detection component is used to monitor the weight of the clothes in real time, and the control component dynamically adjusts the working status of the refrigeration device and the liquid supply component. In this way, when the weight detection component detects that the weight of the clothes is large, the control component controls the refrigeration device to condense the airflow in the circulating air duct and controls the liquid supply component to provide liquid water to condense the airflow in the circulating air duct, thereby improving the condensation effect in the washer-dryer. At the same time, the washer-dryer no longer relies solely on the water in the liquid supply component to condense the moisture in the circulating air duct, thereby reducing water consumption and avoiding the waste problem caused by excessive use of water in the liquid supply component in traditional washer-dryers.

[0026] The washer-dryer provided in the embodiments of the present application is capable of intelligently adjusting the operating status of the refrigeration unit and liquid supply unit. This intelligent control reduces the need for human intervention, improving the washer-dryer's automation and user experience. Through real-time monitoring and adjustment by the control unit, the washer-dryer can utilize the optimal energy configuration at different stages. The control unit controls the operating status of the refrigeration unit and refrigeration unit to condense the airflow in the circulating air duct, achieving intelligent regulation, improving the washer-dryer's drying efficiency, reducing unnecessary energy consumption, and avoiding the waste of condensed water caused by excessive use of the liquid supply unit in traditional washer-dryers.

[0027] In some embodiments of the present application, the control unit includes a first control unit and a second control unit. The first control unit is electrically connected to the refrigeration device and the weight detection unit. The second control unit is electrically connected to the refrigeration device, the weight detection unit, and the liquid supply unit.

[0028] The first control unit is configured to control the refrigeration device to be in an operating state when the mass of the cylinder is less than or equal to a preset mass.

[0029] The second control unit is configured to control the refrigeration device and the liquid supply component to be in a working state when the mass of the cylinder is greater than a preset mass.

[0030] The above technical solution has the following advantages or beneficial effects: by setting up a first control unit and a second control unit, the control unit of the washer-dryer can intelligently control the working status of the refrigeration device and the liquid supply unit according to the mass of the cylinder. When the mass of the cylinder is less than or equal to the preset mass, only the refrigeration device is started to save energy and avoid consuming too much condensed water; when the mass of the cylinder exceeds the preset mass, the refrigeration device and the liquid supply unit are started at the same time to ensure that the washer-dryer can effectively condense the airflow in the circulating air duct under high load conditions, thereby improving the drying efficiency of the washer-dryer. By monitoring the mass of the cylinder in real time through the weight detection unit, the washer-dryer can intelligently adjust the working status of the refrigeration device and the liquid supply unit. This intelligent control reduces the need for human intervention and improves the automation level and user experience of the washer-dryer.

[0031] In some embodiments of the present application, the barrel has a front end and a rear end that are arranged opposite to each other. The front end is provided with a barrel opening that is connected to the cavity. The barrel opening is used for taking clothes in and out.

[0032] The circulating air duct has a circulating air inlet and a circulating air outlet. The circulating air inlet is connected to the first end of the cavity, which is located near the rear end of the cavity. The circulating air outlet is connected to the second end of the cavity, which is located near the front end of the cavity.

[0033] Along the flow direction of the air flow in the circulating air duct, the cooling end and the liquid inlet are arranged at intervals.

[0034] In the circulating air duct, the air flows from the circulating air inlet to the circulating air outlet.

[0035] The above technical solution has the following advantages or beneficial effects: along the direction of air flow, that is, along the direction from the circulating air inlet to the circulating air outlet, the refrigeration end and the liquid inlet are arranged at intervals to ensure that the air flow is first condensed when passing through the refrigeration end to remove excess moisture, and then further condensed through the liquid inlet (if the weight of the clothes is greater than the preset weight). This segmented processing improves the condensation efficiency and ensures that the air flow reaches the best drying conditions before entering the cylinder.

[0036] In some embodiments of the present application, the refrigeration device includes a refrigeration fin, one end of which is located in the circulating air duct and forms a refrigeration end, and the other end of which is located outside the circulating air duct.

[0037] The above technical solution has the following advantages or beneficial effects: By placing one end of the refrigeration fin within the circulating air duct, the fin is in direct contact with the airflow. The fin exchanges heat with the airflow in the circulating air duct, quickly removing heat from the airflow and condensing the airflow in the circulating air duct. The other end of the fin is located outside the circulating air duct, helping to dissipate heat outside the cylinder, preventing heat accumulation within the circulating air duct and affecting the performance of other components.

[0038] In some embodiments of the present application, there are at least two groups of cooling fins, and the at least two groups of cooling fins are spaced apart along the height direction of the box, or at least two groups of cooling fins are spaced apart along the length direction of the box.

[0039] The above technical solution has the following advantages or beneficial effects: The use of multiple groups of refrigeration fins can increase the cooling capacity, ensure that moisture can be effectively removed under heavy loads or high humidity conditions, and improve drying efficiency. By arranging the refrigeration fins at intervals along the height or length direction, a uniform temperature distribution can be achieved, local overcooling or overheating can be avoided, and the uniformity of clothing drying can be improved. At the same time, multiple groups of refrigeration fins can work simultaneously, shortening the time to reach the required temperature and improving the overall efficiency and response speed of the washer-dryer. In addition, multiple groups of refrigeration fins provide redundancy. Even if one group fails, the other groups can continue to work, ensuring the reliability and continuity of the washer-dryer.

[0040] In some embodiments of the present application, the cooling fin includes a cold end and a hot end disposed opposite each other. The cold end is located within the circulating air duct and forms a cooling end. The hot end is located outside the circulating air duct.

[0041] The refrigeration device also includes a heat sink and a fan.

[0042] The heat sink is connected to the hot end and is used to dissipate heat from the hot end. The fan is connected to a side of the heat sink that is away from the hot end, and an air outlet of the fan faces the heat sink.

[0043] The above technical solution has the following advantages or beneficial effects: the heat sink absorbs the heat generated by the hot end of the cooling fin by directly contacting it. This reduces the temperature of the cooling fin and improves the cooling efficiency of the cooling fin. The fan is installed on the side of the heat sink facing away from the cooling fin, with the fan outlet facing the heat sink. The rotation of the fan generates airflow, forcing air to flow through the heat sink, removing heat from the heat sink and further dissipating heat from the cooling fin. Through forced convection, the fan significantly improves the heat dissipation efficiency of the heat sink and the cooling fin. The use of the fan can quickly remove heat from the surface of the heat sink, maintaining a low temperature for the heat sink and the hot end of the cooling fin.

[0044] In some embodiments of the present application, the heat dissipation element includes a substrate and fins.

[0045] The base plate is arranged at one end of the fin close to the cooling plate, and the base plate is connected to the cooling plate.

[0046] One end of the fin is connected to the base plate, and the other end of the fin is connected to the fan.

[0047] The above technical solution has the following advantages or benefits: The substrate is placed at the end of the fins closest to the cooling fins. The substrate is typically made of a highly thermally conductive material (such as aluminum or copper) to ensure rapid heat transfer. The substrate is connected to the cooling fins, allowing the heat sink to dissipate heat directly from the hot end of the cooling fins, enhancing the heat dissipation effect. The fins are typically arranged in a sheet or fin-like pattern to maximize surface area, thereby improving heat dissipation efficiency.

[0048] In some embodiments of the present application, the washer-dryer further includes a liquid collection member. The liquid collection member is located in the circulating air duct, at one end of the circulating air inlet facing the bottom of the cabinet. The liquid collection member has a liquid collection trough, the notch of which faces the cooling fins and the liquid inlet.

[0049] The above technical solution has the following advantages or beneficial effects: The liquid collection element can effectively collect condensed water generated during the condensation process of the airflow in the circulating air duct. By aligning the notch of the liquid collection trough with the cooling fins and the liquid inlet, the condensed water is quickly directed into the trough, preventing water accumulation in the circulating air duct. By promptly collecting the condensed water, the liquid collection element prevents it from evaporating back into the airflow, thereby avoiding an increase in air humidity. This helps maintain a low humidity environment within the drum and improves clothing drying efficiency.

[0050] In some embodiments of the present application, the housing is provided with a housing opening. The housing opening communicates with the housing cavity. A direction intersecting the height direction of the housing is defined as a first direction. The cooling fins, heat sink, and fan are sequentially arranged along the first direction. The fan is located within the housing cavity, between the inner periphery of the housing and the outer periphery of the circulating air duct, with the fan's air inlet end communicating with the housing opening.

[0051] The above technical solution has the following advantages or beneficial effects: the cooling fins, the heat sink and the fan are arranged in sequence along the first direction. This arrangement ensures that heat is transferred from the cooling fins to the heat sink and effectively dissipated through the airflow of the fan.

[0052] In some embodiments of the present application, the washer-dryer further includes a power supply, and the refrigeration device is electrically connected to the power supply.

[0053] The above technical solution has the following advantages or beneficial effects: the power supply provides a stable current to the cooling plate, ensuring that the cooling plate can continue to operate effectively and maintain the required temperature difference. By providing the power supply, the input current of the cooling plate can be precisely adjusted, thereby achieving precise control of the cooling plate temperature.

[0054] In some embodiments of the present application, the drying assembly includes a heater. The heated air is located in the circulating air duct. The heater is positioned relative to the refrigeration unit, near the circulating air outlet, along the direction of airflow within the circulating air duct. The heater is configured to heat the airflow condensed by the refrigeration unit.

[0055] The above technical solution has the following advantages or beneficial effects: In the heater, the airflow is heated to a higher temperature. The heated airflow has a higher temperature and lower relative humidity, which enables it to more effectively absorb and carry moisture from clothing. The heated airflow enters the drying chamber of the washer-dryer through the circulating air outlet, where it comes into contact with the clothing and absorbs moisture from the clothing. The moisture-absorbed airflow then re-enters the circulating air duct, repeating the condensation and heating process, forming a highly efficient drying cycle. BRIEF DESCRIPTION OF THE DRAWINGS

This air is then cooled by cooling water and dehydrated before being converted back into dry air and returned to the drying system. During the drying process, condensing washer-dryers use condensed water to extract moisture from the wet air, resulting in a waste of water resources.

[0086] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0087] Reference Figures 1 to 7 As shown, an embodiment of the present application provides a washer-dryer. The washer-dryer includes a housing, a drum 100, a circulating air duct 200, a liquid supply unit 700, a refrigeration unit 300, a drying assembly 400, a weight detection unit 500, and a control unit 600. The housing has a receiving cavity. The drum 100 is located in the receiving cavity. The drum 100 has a cavity.

[0088] A circulation air duct 200 is provided between the outer periphery of the barrel 100 and the inner periphery of the box body. The circulation air duct 200 is communicated with the cavity and has a liquid inlet 230 .

[0089] The liquid supply member 700 has a liquid supply cavity which is communicated with the liquid inlet 230 .

[0090] The refrigeration end of the refrigeration device 300 is located in the circulating air duct 200. The refrigeration device 300 is used to condense the air flow entering the circulating air duct 200 through the cylinder 100.

[0091] The drying component 400 is located in the circulating air duct 200 and is used to heat the air flow in the circulating air duct 200 .

[0092] The weight detection member 500 is used to detect the weight of the cylinder 100 .

[0093] For example, after the washer-dryer completes washing, that is, after the washer-dryer completes the washing and dehydration processes, the washer-dryer enters a drying state, and the washer-dryer dries the clothes in the cavity of the drum 100 .

[0094] In some embodiments, the weight detection element 500, the refrigeration device 300, and the liquid supply element 700 are all electrically connected to the control element 600. The control element 600 is configured to control the refrigeration device 300 to operate according to the detection result of the weight detection element 500, so that the airflow in the circulation duct 200 is condensed.

[0095] In other embodiments, the weight detection component 500, the refrigeration device 300, and the liquid supply component 700 are all electrically connected to the control component 600. The control component 600 is configured to control the refrigeration device 300 and the liquid supply component 700 to operate according to the detection result of the weight detection component 500, so as to condense the airflow in the circulation duct 200.

[0096] The washer-dryer provided in an embodiment of the present application is provided with a refrigeration device 300, a liquid supply component 700, a weight detection component 500, and a control component 600. The refrigeration device 300 is used to condense the airflow carrying moisture in the circulating air duct 200. The liquid supply component 700 is used to supply liquid, such as water, to the circulating air duct 200 to condense the airflow carrying moisture in the circulating air duct 200. The weight detection component 500 monitors the weight of the clothes in real time, and the control component 600 dynamically adjusts the operating status of the refrigeration device 300 and the liquid supply component 700 to adapt to different clothing loads.

[0097] When the weight detection component 500 detects that the weight of the clothes is low, the control component 600 controls the refrigeration device 300 to condense the air flow in the circulating air duct 200, stops the use of the liquid supply component 700, reduces unnecessary energy consumption, and avoids the waste problem caused by excessive use of condensed water from the liquid supply component 700 in traditional washer-dryers.

[0098] When the weight detection component 500 detects that the weight of the clothes is heavy, the control component 600 controls the refrigeration device 300 to condense the airflow in the circulating air duct 200, and controls the liquid supply component 700 to provide liquid water to condense the airflow in the circulating air duct 200, thereby improving the condensation effect in the washer-dryer. At the same time, the washer-dryer no longer relies solely on the water of the liquid supply component 700 to condense the moisture in the circulating air duct 200, thereby reducing water consumption and avoiding the waste problem caused by excessive use of water from the liquid supply component 700 in traditional washer-dryers.

[0099] Through real-time monitoring and adjustment by the control component 600, the washer-dryer can use the optimal energy configuration at different stages. The control component 600 controls the working status of the refrigeration device 300 and the liquid supply component 700 to condense the air flow carrying moisture in the circulating air duct 200, thereby realizing intelligent adjustment, improving the drying efficiency of the washer-dryer, reducing unnecessary energy consumption, and avoiding the waste problem caused by excessive use of condensed water from the liquid supply component 700 in traditional washer-dryers.

[0100] In addition, when the clothes load is too heavy, the refrigeration device 300 and the liquid supply part 700 are both in working state. This dual condensation mechanism provides stronger moisture removal ability when there are more clothes, ensuring the drying effect of the washer-dryer and improving the drying efficiency of the washer-dryer.

[0101] As an achievable embodiment, the control unit 600 includes a first control unit and a second control unit; the first control unit is electrically connected to the refrigeration device 300 and the weight detection unit 500. The second control unit is electrically connected to the refrigeration device 300, the weight detection unit 500, and the liquid supply unit 700.

[0102] The first control unit is configured to control the refrigeration device 300 to be in an operating state when the mass of the cylinder 100 is less than or equal to a preset mass.

[0103] The second control unit is configured to control the refrigeration device 300 and the liquid supply component 700 to be in a working state when the mass of the cylinder 100 is greater than a preset mass.

[0104] When the control unit 600 controls the weight detection unit 500 to detect the weight of the cylinder 100, when the weight of the cylinder 100 detected by the weight detection unit 500 is less than the preset weight, that is, when the weight of the clothes is small, the first control unit controls the refrigeration device 300 to be in a working state and controls the liquid supply unit 700 to be in a non-working state. At this time, the refrigeration device 300 condenses the airflow in the circulating air duct 200 to reduce the moisture in the airflow and prevent the over-humidified airflow from affecting the drying of clothes. The drying component 400 then heats the condensed airflow to a suitable temperature, and then enters the cavity of the cylinder 100 to dry the clothes. Through circulation, the airflow continuously removes moisture from the clothes, achieving efficient drying.

[0105] When the control part 600 controls the weight detection part 500 to detect the weight of the cylinder 100, when the weight of the cylinder 100 detected by the weight detection part 500 is greater than the preset weight, that is, when the weight of the clothes is large, the second control part controls the refrigeration device 300 and the liquid supply part 700 to be in working state, the refrigeration device 300 condenses the airflow, and the liquid supply part 700 supplies liquid (such as water) to the circulating air duct 200 through the liquid inlet 230, further enhancing the condensation effect. The liquid provided by the liquid supply part 700 is in direct contact with the airflow, reducing the temperature of the airflow and promoting the condensation of water molecules in the airflow. The drying component 400 heats the condensed airflow to reach a suitable temperature, and then enters the cavity of the cylinder 100 for drying. This dual condensation mechanism ensures that moisture can be efficiently removed even when there are a lot of clothes, maintaining drying efficiency.

[0106] The washer-dryer provided in the embodiment of the present application can intelligently control the working states of the refrigeration device 300 and the liquid supply component 700 according to the mass of the cylinder 100 by setting a first control unit and a second control unit. When the mass of the cylinder 100 is less than or equal to the preset mass, only the refrigeration device 300 is started to save energy and avoid consuming too much condensed water; and when the mass of the cylinder 100 exceeds the preset mass, the refrigeration device 300 and the liquid supply component 700 are started at the same time to ensure that the washer-dryer can effectively condense the airflow in the circulating air duct 200 under high load conditions, thereby improving the drying efficiency of the washer-dryer. By monitoring the mass of the cylinder 100 in real time through the weight detection component 500, the washer-dryer can intelligently adjust the working states of the refrigeration device 300 and the liquid supply component 700. This intelligent control reduces the need for human intervention and improves the automation level and user experience of the washer-dryer.

[0107] Exemplarily, the preset weight may be 4 kg, 5 kg, or 6 kg.

[0108] Exemplarily, the drying assembly 400 further includes a circulation fan. Located in the circulating air duct 200, the circulation fan promotes airflow in the washer-dryer, ensuring that the air heated by the drying assembly 400 evenly passes through the clothes in the cavity of the drum 100. Simultaneously, the circulation fan helps carry away the air containing moisture evaporated from the clothes, which is condensed by the refrigeration device 300 or the liquid supply unit 700. The enhanced airflow can accelerate the evaporation process of the moisture, thereby shortening the drying time and improving the overall efficiency of the dryer.

[0109] Illustratively, the weight detecting member 500 includes a weight sensor.

[0110] For example, the liquid supply component 700 may be a liquid supply tank or a tap water interface.

[0111] Illustratively, the control component 600 includes a controller.

[0112] In one practicable embodiment, the drum body 100 has a front end and a rear end disposed opposite each other. A drum opening 110 is provided at the front end, communicating with the cavity. The drum opening 110 is used for placing and removing clothing. The front end opening 110 facilitates the user's placement of clothing and also facilitates maintenance and cleaning.

[0113] Reference Figure 4 and Figure 8 As shown, the circulating air duct 200 has a circulating air inlet 210 and a circulating air outlet 220. The circulating air inlet 210 is connected to the first end of the cavity. The first end of the cavity is located near the rear end. The circulating air outlet 220 is connected to the second end of the cavity. The second end of the cavity is located near the front end.

[0114] Along the flow direction of the air flow in the circulating air duct 200 , the cooling end and the liquid inlet 230 are arranged at intervals.

[0115] In the circulating air duct 200, the air flows from the circulating air inlet 210 to the circulating air outlet 220. The flow direction of the air flow is as follows: Figure 4 The direction is indicated by the black solid arrow.

[0116] In some embodiments, the circulation air duct 200 is a structure defined by the outer periphery of the cylinder 100 and the inner periphery of the box.

[0117] In other embodiments, the circulation duct 200 is a passage made of metal or plastic material, and the circulation duct 200 can guide air flow.

[0118] For example, when the washer-dryer is in the drying state, the air flow in the cavity of the drum 100 flows to the circulating air duct 200 through the circulating air inlet 210, and is condensed by the refrigeration device 300 or the liquid supply part 700 and heated by the drying component 400, and then flows to the cavity of the drum 100 again through the circulating air outlet 220. By setting the circulating air inlet 210 and the circulating air outlet 220, the flow path of the air flow in the cavity of the drum 100 is clear, flowing from the rear end to the front end, ensuring that the air flow can pass through the entire drum 100 evenly, fully contacting all clothes, and improving the drying efficiency.

[0119] Along the direction of airflow, that is, from the circulating air inlet 210 to the circulating air outlet 220, the cooling end and the liquid inlet 230 are spaced apart to ensure that the airflow is first condensed and excess moisture is removed when passing through the cooling end, and then further condensed through the liquid inlet 230 (if the weight of the clothes is greater than a preset weight). This segmented processing improves condensation efficiency and ensures that the airflow reaches optimal drying conditions before entering the drum 100. By providing the circulating air outlet 220 and the circulating air outlet 220 at the front and rear ends of the drum 100, respectively, the structural compactness of the washer-dryer is improved, saving internal space in the drum 100.

[0120] As one achievable embodiment, the drying assembly 400 includes a heater. The heated air is located in the circulating air duct 200. The heater is positioned relative to the refrigeration unit 300, near the circulating air outlet 220, along the flow direction of the air within the circulating air duct 200. The heater is used to heat the airflow condensed by the refrigeration unit 300.

[0121] For example, along the flow direction of the airflow in the circulating air duct 200, the heater is arranged after the refrigeration device 300, close to the circulating air outlet 220. This arrangement enables the heater to heat the airflow that has been condensed by the refrigeration device 300.

[0122] The air flow enters the circulating air duct 200 and first passes through the refrigeration device 300. The refrigeration device 300 condenses the moisture in the air flow into liquid by lowering the temperature of the air flow and separates it from the air flow. The condensed air flow continues to flow along the air duct and enters the heater area. In the heater, the air flow is heated to a higher temperature. The heated air flow has a higher temperature and lower relative humidity, which enables it to more effectively absorb and carry moisture from the clothes. The heated air flow enters the drying chamber of the washer-dryer through the circulating air outlet 220, comes into contact with the clothes, and absorbs moisture from the clothes. The air flow after moisture absorption enters the circulating air duct 200 again, repeating the condensation and heating process to form an efficient drying cycle.

[0123] As a feasible implementation method, refer to Figure 9 and Figure 10 As shown, the refrigeration device 300 includes a refrigeration fin 310. One end of the refrigeration fin 310 is located in the circulation duct 200 and forms a refrigeration end, and the other end of the refrigeration fin 310 is located outside the circulation duct 200.

[0124] For example, by placing one end of the refrigeration fin 310 in the circulating air duct 200, the refrigeration fin 310 is in direct contact with the airflow. The refrigeration fin 310 performs heat exchange with the airflow in the circulating air duct 200, and the refrigeration fin 310 quickly takes away the heat in the airflow, thereby condensing the airflow in the circulating air duct 200. The other end of the refrigeration fin 310 is located outside the circulating air duct 200, which helps to discharge heat to the outside of the cylinder 100, avoiding heat accumulation inside the circulating air duct 200 and affecting the performance of other components. By setting the refrigeration fin 310 to be in direct contact with the airflow, the refrigeration fin 310 can quickly reduce the temperature of the airflow, promote the condensation and collection of moisture, and improve the efficiency of the drying process.

[0125] The cooling fin 310 includes a cold end and a hot end that are arranged opposite to each other. The cold end is located in the circulation duct 200 and forms a cooling end. The hot end is located outside the circulation duct 200.

[0126] Refrigeration fin 310 comprises multiple thermocouple pairs made of a semiconductor material, typically a compound of bismuth and tellurium. Refrigeration fin 310 typically has a stacked structure. These thermocouple pairs are arranged in series or parallel when an electric current is applied. This creates a temperature difference, enhancing the cooling effect. Refrigeration fin 310 has two surfaces: one for absorbing heat, forming the cold end, and the other for releasing heat, forming the hot end. When current flows through it, the cold end cools and the hot end heats.

[0127] During use, when a direct current passes through the cooling fin 310, it flows through the thermocouple pairs in the semiconductor material. Due to the Peltier effect, the current causes one end of the thermocouple pair to absorb heat (the cold end) and the other end to release heat (the hot end). The temperature of the cold end decreases, absorbing heat from the airflow in the circulating air duct 200, while the temperature of the hot end increases, releasing heat into the environment. By continuously supplying current, the cooling fin 310 can maintain a low temperature at the cold end, achieving a continuous cooling effect.

[0128] For example, because the cooling fins 310 have no moving parts, they operate silently, are highly reliable, and require minimal maintenance. Furthermore, by adjusting the current, the temperature of the cooling fins 310 can be precisely controlled. Furthermore, the cooling fins 310 can quickly respond to current changes, quickly reaching the desired temperature.

[0129] As a feasible implementation method, refer to Figure 7 As shown, the washer-dryer also includes a power supply 800. The refrigeration device 300 and the power supply 800 are electrically connected. The power supply 800 provides a stable current to the cooling fins 310, ensuring that the cooling fins 310 can continue to operate effectively and maintain the required temperature difference. By providing the power supply 800, the input current of the cooling fins 310 can be precisely adjusted, thereby achieving precise control of the temperature of the cooling fins 310. In addition, the power supply 800 also provides a stable current to the fan 330.

[0130] The power supply 800 includes a power module, a power management unit, a power switch, and a relay. The power module converts external power (e.g., AC power) into DC power suitable for the cooling plate 310. The power management unit manages and distributes power, ensuring a stable power supply to the cooling plate 310. The power switch and relay control the power supply, ensuring that the cooling plate 310 can be turned on and off when needed.

[0131] As a feasible implementation method, refer to Figure 9 As shown, the number of cooling fins 310 is at least two groups.

[0132] In some embodiments, at least two groups of cooling fins 310 are spaced apart along the height direction of the box.

[0133] In other embodiments, at least two groups of cooling fins 310 are spaced apart along the length of the box.

[0134] For example, the use of multiple groups of refrigeration fins 310 can increase the cooling capacity, ensure that moisture can still be effectively removed under heavy loads or high humidity conditions, and improve drying efficiency. By arranging the refrigeration fins 310 at intervals along the height or length direction, a uniform temperature distribution can be achieved, local overcooling or overheating can be avoided, and the uniformity of clothing drying can be improved. At the same time, multiple groups of refrigeration fins 310 can work simultaneously, shortening the time to reach the required temperature and improving the overall efficiency and response speed of the washer-dryer. In addition, multiple groups of refrigeration fins 310 provide redundancy. Even if one group fails, the other groups can continue to work, ensuring the reliability and continuity of the washer-dryer.

[0135] As a feasible implementation method, refer to Figure 9 As shown, the refrigeration device 300 further includes a heat sink 320 and a fan 330 .

[0136] The heat sink 320 is connected to the hot end and is used to dissipate heat from the hot end. The fan 330 is connected to the side of the heat sink 320 facing away from the hot end, and the air outlet of the fan 330 faces the heat sink 320.

[0137] For example, the flow of current in the cooling fins 310 creates a temperature difference, with the cold end absorbing heat and the hot end releasing it. During the cooling process, a significant amount of heat accumulates at the hot end. If not dissipated promptly, this heat will cause the hot end's temperature to rise, reducing the efficiency of the cooling fins 310. The heat sink 320, by directly contacting the hot end of the cooling fins 310, absorbs the heat generated, thereby lowering the temperature of the cooling fins 310 and improving its cooling efficiency. The fan 330 is mounted on the side of the heat sink 320 facing away from the cooling fins 310, with the air outlet facing the heat sink 320. The rotation of the fan 330 generates airflow, forcing air through the heat sink 320, removing heat from it and dissipating heat from the cooling fins 310. Through forced convection, the fan 330 significantly improves the heat dissipation efficiency of both the heat sink 320 and the cooling fins 310. The fan 330 quickly removes heat from the surface of the heat sink 320, maintaining low temperatures for both the heat sink 320 and the hot end of the cooling fins 310.

[0138] As a feasible implementation, the heat sink 320 includes a base plate 321 and fins 322 .

[0139] The base plate 321 is disposed at one end of the fin 322 close to the cooling fin 310 , and the base plate 321 is connected to the cooling fin 310 .

[0140] One end of the fin 322 is connected to the base plate 321 , and the other end of the fin 322 is connected to the fan 330 .

[0141] Exemplarily, substrate 321 is positioned at the end of fins 322 near cooling fin 310. Substrate 321 is typically made of a highly thermally conductive material (such as aluminum or copper) to ensure rapid heat conduction. Substrate 321 is connected to cooling fin 310, allowing heat sink 320 to directly dissipate heat from the hot end of cooling fin 310, enhancing heat dissipation. Fins 322 are typically arranged in a sheet or fin-like pattern to maximize surface area, thereby improving heat dissipation efficiency.

[0142] The heat generated by the hot end of the refrigeration fin 310 is first conducted to the fin 322. Since the fin 322 is connected to the refrigeration fin 310 through the base plate 321, the heat can be quickly absorbed by the fin 322. The fin 322 diffuses the absorbed heat through its large surface area. The design of the fin 322 (such as the dense fin structure) increases the contact area with the air, promoting the conduction and diffusion of heat. The fan 330 generates an airflow, which takes away the heat when passing through the fin 322. The airflow can effectively pass through the entire surface of the fin 322, forming forced convection, which significantly improves the heat dissipation efficiency. The continuous operation of the fan 330 ensures that the air continues to flow, forming a cooling cycle. The cold air is sucked in, absorbs heat when passing through the fin 322, and is then discharged to the outside of the washer-dryer, taking away the heat.

[0143] As a feasible embodiment, the washer-dryer also includes a liquid collecting member. The liquid collecting member is located in the circulating air duct 200, and the liquid collecting member is located at one end of the circulating air inlet 210 facing the bottom of the box. The liquid collecting member has a liquid collecting groove, and the groove of the liquid collecting groove faces the cooling fin 310 and the liquid inlet 230. In this way, the liquid collecting member can effectively collect the condensed water generated during the condensation process of the air flow in the circulating air duct 200. The flow direction of the condensed water is as shown in FIG. Figure 4 The hollow arrow indicates the direction. By aligning the notch of the sump with the cooling fins 310 and the liquid inlet 230, condensed water is quickly directed into the sump, preventing accumulation of moisture in the circulating air duct 200. By promptly collecting condensed water, the sump prevents it from evaporating back into the airflow, thereby avoiding an increase in humidity in the airflow. This helps maintain a low humidity environment within the drum 100 and improves clothing drying efficiency.

[0144] For example, the liquid collecting member may be a liquid collecting box having a liquid collecting opening facing the cooling fins 310 and the liquid inlet 230 .

[0145] Exemplarily, the washer-dryer also includes a pump body. The pump body is connected to the liquid collection box via a tube body, and the pump body is used to collect the liquid in the liquid collection box to the outside of the washer-dryer. The pump body can automatically discharge the condensed water in the liquid collection box to the outside of the washer-dryer, reducing the frequency and trouble of users manually emptying the liquid collection box, and improving the degree of automation of the washer-dryer. By draining the condensed water in a timely manner, the capacity of the liquid collection box will not become a limiting factor, ensuring that the washer-dryer can operate continuously for a long time without interruption for drainage. In this way, the liquid collection part achieves automatic drainage, preventing the risk of overflowing the liquid collection box due to water being full, and avoiding potential damage to other components inside the washer-dryer due to water overflow.

[0146] As a feasible embodiment, the housing is provided with a housing opening. The housing opening communicates with the housing cavity. A direction intersecting the height direction of the housing is defined as a first direction. The cooling fins 310, the heat sink 320, and the fan 330 are sequentially arranged along the first direction. The fan 330 is located in the housing cavity, between the inner periphery of the housing and the outer periphery of the circulating air duct 200. The air inlet end of the fan 330 communicates with the housing opening.

[0147] For example, the cooling fins 310 , the heat sink 320 , and the fan 330 are sequentially arranged along a first direction, such that heat is conducted from the cooling fins 310 to the heat sink 320 and effectively dissipated through the airflow of the fan 330 .

[0148] External air enters the accommodating chamber through the opening of the box body and is sucked in by the air inlet end of the fan 330. When the inhaled air flows through the heat sink 320, it takes away the heat absorbed by the heat sink 320 from the hot end of the refrigeration fin 310. This process is enhanced by the forced convection effect of the fan 330. The heated air is discharged from the accommodating chamber by the fan 330, enters the circulating air duct 200 or is directly discharged outside the box body, completing the effective dissipation of heat. The continuous operation of the fan 330 maintains the circulation of air, ensuring that the hot end of the refrigeration fin 310 is always at a lower temperature, maintaining the efficient operation of the washer-dryer.
