Description

[0001] The application claims priority to the Chinese Patent Application No. 202211226427.4, filed on October 9, 2022, and entitled "A clothes dryer", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of clothes drying equipment, and in particular to a clothes dryer. BACKGROUND

[0003] With the acceleration of the pace of life, the problem of long airing of washed clothes in low temperature weather is increasingly prominent. In order to solve the problem of long airing of clothes, a clothes dryer emerges as the times require. The clothes dryer mainly refers to a cleaning household appliance that uses electric heating to evaporate the moisture in washed clothes instantly, thereby drying the clothes.

[0004] In the related art, the clothes dryer includes a drying drum and a circulating air duct in communication with the drying drum. In operation, the circulating air in the circulating air duct is heated by a heater into dry hot air. After the dry hot air is blown into the drying drum, the water on the wet clothes is taken away to become warm and humid air. The warm and humid air enters a condensing system, is cooled at the same time, and releases water to become dry cold air. The dry cold air enters the heater again and is heated into dry hot air that enters the drying drum. The process is repeated to achieve clothes drying.

[0005] However, using the above-mentioned clothes dryer to dry clothes can easily cause cross-contamination between different types of clothes. SUMMARY

[0046] With the improvement of people's living standards, people's demand for clothes dryers is more and more. Especially in the case of difficult drying of clothes in winter in the north and humid weather in the south.

[0047] The clothes dryer is mainly divided into heat pump type, condensing type and hot air type. Among them, the heat pump type clothes dryer realizes internal heat transfer through a heat pump system, which usually includes a compressor, an evaporator, a condenser and a fan, etc., has the advantages of high energy efficiency and low power consumption, and is pursued by the market.

[0048] In the related art, the heat pump type clothes dryer includes a drying barrel and a circulating air duct communicating with the drying barrel. In use, different types of clothes such as adult clothes, outerwear, underwear, children's clothes and pet supplies need to be dried through the drying barrel. In this way, cross contamination between different types of clothes is easily caused, thereby threatening the health of users.

[0049] Therefore, in the present application, the existing clothes dryer is optimized to reduce the risk of cross contamination between different types of clothes.

[0050] Referring to Figure 1 , the present disclosure provides a clothes dryer 100, which includes a housing 1. The housing 1 is provided with a drying chamber and an air duct. The drying chamber is used to place clothes, and the air duct is used to exchange air with the drying chamber.

[0051] Among them, the drying chamber includes a first drying chamber 11 and a second drying chamber 12 which are independent of each other, and the air duct includes a first air duct 13 and a second air duct 14 which are independent of each other. The first drying chamber 11 has a first air inlet 111 and a first air outlet 112. One end of the first air duct 13 communicates with the first air inlet 111, and the other end communicates with the first air outlet 112. The second drying chamber 12 has a second air inlet 121 and a second air outlet 122. One end of the second air duct 14 communicates with the second air inlet 121, and the other end communicates with the second air outlet 122. That is to say, the housing 1 is provided with two independent drying chambers, and each drying chamber communicates with a separate air duct.

[0052] It should be noted that the clothes dryer 100 can include a larger number of drying chambers and air ducts, and each drying chamber corresponds to an air duct. For example, the clothes dryer 100 can include three drying chambers and three air ducts, or four drying chambers and four air ducts. Among them, the setting mode of the drying chamber and the air duct can refer to the setting mode of the first drying chamber 11 and the first air duct 13, and the present disclosure will not be repeated here.

[0053] On this basis, referring to Figure 2 , the clothes dryer 100 further includes a heat pump system 2, which is arranged in the housing 1 (as shown in Figure 1 ) and includes a compressor 21, a control valve 22, a first heat exchanger assembly 23 and a second heat exchanger assembly 24. The heat pump system 2 is used for heat exchange with the drying chamber.

[0054] The control valve 22 is connected with the compressor 21. The first heat exchanger assembly 23 is arranged in the first air duct 13 (as shown in Figure 1 ) and connected with the control valve 22 and the compressor 21 to form a first refrigerant circulation loop. That is, the compressor 21, the control valve 22 and the first heat exchanger assembly 23 are connected in series to form the first refrigerant circulation loop.

[0055] The second heat exchanger assembly 24 is arranged in the second air duct 14 (as shown in Figure 1 ) and connected in parallel with the first heat exchanger assembly 23. The second heat exchanger assembly 24 is connected with the control valve 22 and the compressor 21 to form a second refrigerant circulation loop. That is, the compressor 21, the control valve 22 and the second heat exchanger assembly 24 are connected in series to form the second refrigerant circulation loop.

[0056] In this way, the air in the first air duct 13 can be heated by the first heat exchanger assembly 23, and the heated air can enter the first drying chamber 11 to exchange heat with the first drying chamber 11, thereby achieving drying of the clothes in the first drying chamber 11. The air in the second air duct 14 can also be heated by the second heat exchanger assembly 24, and the heated air can enter the second drying chamber 12 to exchange heat with the second drying chamber 12, thereby achieving drying of the clothes in the second drying chamber 12. In this way, different drying chambers can be selected to dry different types of clothes, thereby reducing the risk of cross-contamination between different types of clothes.

[0057] It can be understood that, as shown in Figure 2 and Figure 3 , the compressor 21 generally has an air outlet 211 and an air return port 212. The control valve 22 can be connected with the air outlet 211 of the compressor 21 or the air return port 212 of the compressor 21, which can be selected according to actual conditions, and the present disclosure does not make specific limitations thereon.

[0058] As shown in Figure 2 , when the control valve 22 is connected with the air outlet 211 of the compressor 21, the first heat exchanger assembly 23 and the second heat exchanger assembly 24 are connected with the air return port 212 of the compressor 21 to form the first refrigerant circulation loop and the second refrigerant circulation loop. As shown in Figure 3 , when the control valve 22 is connected with the air return port 212 of the compressor 21, the first heat exchanger assembly 23 and the second heat exchanger assembly 24 are connected with the air outlet 211 of the compressor 21 to form the first refrigerant circulation loop and the second refrigerant circulation loop.

[0059] Exemplarily, as shown in Figure 2As shown, the control valve 22 is connected with the gas outlet 211 of the compressor 21, and the first heat exchanger assembly 23 and the second heat exchanger assembly 24 are connected with the gas return port 212 of the compressor 21.

[0060] It should be noted that the control valve 22 is used to control the communication or disconnection of the first refrigerant circulation loop and the second refrigerant circulation loop.

[0061] In this way, the first refrigerant circulation loop can be controlled to be connected and the second refrigerant circulation loop to be disconnected by the control valve 22, so that the clothes are dried by the first drying chamber 11; the second refrigerant circulation loop can be controlled to be connected and the first refrigerant circulation loop to be disconnected by the control valve 22, so that the clothes are dried by the second drying chamber 12; and the first refrigerant circulation loop and the second refrigerant circulation loop can be controlled to be connected by the control valve 22, so that the clothes are dried by the first drying chamber 11 and the second drying chamber 12 at the same time. In this way, the diversified needs of users can be met, and the use experience of users can be improved.

[0062] It should be noted that in the case where the clothes dryer 100 includes a larger number of drying chambers and air ducts, the heat pump system 2 includes the same number of heat exchanger assemblies, and one heat exchanger assembly is arranged in each air duct. For example, the heat pump system 2 can include three heat exchanger assemblies, or four heat exchanger assemblies. The arrangement of the heat exchanger assemblies can refer to the arrangement of the first heat exchanger assembly 23, which will not be described herein again.

[0063] In addition, as shown, Figure 4 The clothes dryer 100 can further include a first air fan 3, which is arranged in the first air duct 13, and the airflow introduced by the first air fan 3 enters the first drying chamber 11 through the first air inlet 111 and enters the first air duct 13 through the first air outlet 112.

[0064] In this way, the circulation rate of air in the first air duct 13 and the first drying chamber 11 can be improved, thereby improving the drying efficiency of the clothes dryer 100.

[0065] It should be noted that the clothes dryer 100 can further include a second air fan 4, which is arranged in the second air duct 14, and the airflow introduced by the second air fan 4 enters the second drying chamber 12 through the second air inlet 121 and enters the second air duct 14 through the second air outlet 122.

[0066] In this way, the circulation rate of air in the second air duct 14 and the second drying chamber 12 can be improved, thereby improving the drying efficiency of the clothes dryer 100.

[0067] In some embodiments, referring to Figure 5 and Figure 6The clothes dryer 100 further comprises a first sterilization device 5, which is arranged in the first drying chamber 11 or the first air duct 13. That is, the first sterilization device 5 can be arranged in the first drying chamber 11 or the first air duct 13, and the specific arrangement can be selected according to actual conditions, which is not limited in the disclosure.

[0068] In this way, when the clothes are dried by the first drying chamber 11, the clothes in the first drying chamber 11 can be sterilized and disinfected by the first sterilization device 5, so that the clothes dryer 100 achieves the sterilization and disinfection effect.

[0069] The first sterilization device 5 can be an ultraviolet (UV) generating device, an ozone generating device, or other devices with sterilization and disinfection effects. The specific device can be selected according to actual conditions, which is not limited in the disclosure.

[0070] It should be noted that the ozone generating device can generate ozone, and the ozone can be used to sterilize and disinfect the clothes; the ultraviolet generating device can emit ultraviolet light, and the ultraviolet light can be used to sterilize and disinfect the clothes.

[0071] As shown in Figure 5 , the first sterilization device 5 is an ultraviolet generating device, and the ultraviolet generating device is arranged in the first drying chamber 11. In this way, the ultraviolet light emitted by the ultraviolet generating device can directly irradiate the clothes in the first drying chamber, and the clothes in the first drying chamber 11 can be sterilized and disinfected.

[0072] In some embodiments, referring to Figure 7 and Figure 8 , the clothes dryer 100 further comprises a second sterilization device 6, which is arranged in the second drying chamber 12 or the second air duct 14. That is, the second sterilization device 6 can be arranged in the second drying chamber 12 or the second air duct 14, and the specific arrangement can be selected according to actual conditions, which is not limited in the disclosure.

[0073] In this way, when the clothes are dried by the second drying chamber 12, the clothes in the second drying chamber 12 can be sterilized and disinfected by the second sterilization device 6, so that the clothes dryer 100 achieves the sterilization and disinfection effect.

[0074] The second sterilization device 6 can be an ultraviolet (UV) generating device, an ozone generating device, or other devices with sterilization and disinfection effects. The specific device can be selected according to actual conditions, which is not limited in the disclosure.

[0075] As shown in Figure 7As shown, the second sterilization device 6 is an ultraviolet light generating device, and the ultraviolet light generating device is arranged in the second drying chamber 12. In this way, the ultraviolet light emitted by the ultraviolet light generating device can directly irradiate the clothes in the second drying chamber, and sterilize and disinfect the clothes in the second drying chamber 12.

[0076] The laundry dryer 100 provided by the embodiments of the present disclosure comprises two drying chambers independent of each other, and two air ducts independent of each other, wherein each drying chamber corresponds to an air duct and communicates with the corresponding air duct. On this basis, a heat exchanger assembly is arranged in each air duct, and the heat exchanger assembly is connected with the compressor 21 to form a refrigerant circulation loop. In this way, the drying of clothes can be realized by the two drying chambers. In this way, when the clothes are dried, one of the drying chambers can be selected to dry clothes such as adult clothes and outerwear, and the other drying chamber can be selected to dry clothes such as children's clothes and underwear. In this way, the risk of cross contamination between different types of clothes can be reduced. In addition, the two heat exchanger assemblies share one compressor 21 through the control valve 22, which is conducive to reducing the cost.

[0077] In some embodiments, as shown, Figure 2 The control valve 22 is a three-way electromagnetic valve, which has a first gas inlet end 221, a first gas outlet end 222, and a second gas outlet end 223. The first gas inlet end 221 is connected with the gas outlet 211 of the compressor 21, the first gas outlet end 222 is connected with the first heat exchanger assembly 23, and the second gas outlet end 223 is connected with the second heat exchanger assembly 24.

[0078] In this way, by controlling the first gas inlet end 221 and the first gas outlet end 222 of the three-way electromagnetic valve to be in communication, and the first gas inlet end 221 and the second gas outlet end 223 to be disconnected, the first refrigerant circulation loop is controlled to be in communication and the second refrigerant circulation loop is controlled to be disconnected. At this time, the drying of clothes can be realized through the first drying chamber 11. By controlling the first gas inlet end 221 and the second gas outlet end 223 of the three-way electromagnetic valve to be in communication, and the first gas inlet end 221 and the first gas outlet end 222 to be disconnected, the second refrigerant circulation loop is controlled to be in communication and the first refrigerant circulation loop is controlled to be disconnected. At this time, the drying of clothes can be realized through the second drying chamber 12. By controlling the first gas inlet end 221 and the first gas outlet end 222 of the three-way electromagnetic valve to be in communication, and the first gas inlet end 221 and the second gas outlet end 223 to be disconnected, the first refrigerant circulation loop and the second refrigerant circulation loop are controlled to be in communication. At this time, the drying of clothes can be realized through the first drying chamber 11 or the second drying chamber 12.

[0079] The three-way electromagnetic valve is used to control the communication or disconnection of the first refrigerant circulation loop and the second refrigerant circulation loop, which is simple in structure and easy to realize.

[0080] It can be understood that, as Figure 9 shown, the control valve 22 can also be two two-way electromagnetic valves, which are a first two-way electromagnetic valve 224 and a second two-way electromagnetic valve 225. The first two-way electromagnetic valve 224 has a second gas inlet end 2241 connected to the gas outlet 211 of the compressor 21 and a third gas outlet end 2242 connected to the first heat exchanger assembly 23. The second two-way electromagnetic valve 225 has a third gas inlet end 2251 connected to the gas outlet 211 of the compressor 21 and a fourth gas outlet end 2252 connected to the second heat exchanger assembly 24.

[0081] In this way, the first two-way electromagnetic valve 224 can be used to control the connection or disconnection of the first refrigerant circulation loop, and the second two-way electromagnetic valve 225 can be used to control the connection or disconnection of the second refrigerant circulation loop.

[0082] As can be seen from the above, the control valve 22 can be a three-way electromagnetic valve or two two-way electromagnetic valves, which can be selected according to actual conditions, and the present disclosure does not make specific limitations.

[0083] Hereinafter, some embodiments of the present disclosure will be described illustratively taking the control valve 22 as a three-way electromagnetic valve.

[0084] In some embodiments, referring to Figure 10 , the first heat exchanger assembly 23 includes a first condenser 231 and a first evaporator 232. The first condenser 231 is connected to the first gas outlet end 222, and the first evaporator 232 is connected in series with the first condenser 231 and connected to the gas return port 212 of the compressor 21 to form a first refrigerant circulation loop.

[0085] As shown in Figure 11 , the first evaporator 232 is arranged on the windward side of the first condenser 231. That is, the air entering the first air duct 13 from the first air outlet 112 of the first drying chamber 11 will pass through the first evaporator 232 and the first condenser 231 in sequence.

[0086] In this way, when drying clothes by using the first drying chamber 11, the air in the first air duct 13 is heated into dry hot air by the first condenser 231, and enters the first drying chamber 11 through the first air inlet 111; then the dry hot air becomes warm and humid air by taking away the moisture on the wet clothes; the warm and humid air becomes dry cold air by being cooled and precipitating moisture under the action of the first evaporator 232 after entering the first air duct 13 through the first air outlet 112; the dry cold air is heated into dry hot air again when passing through the first condenser 231; thus, the drying of clothes is realized through the above-mentioned cycle.

[0087] On this basis, referring to Figure 12 , the first heat exchanger assembly 23 can further include a first electronic expansion valve 233, which is connected in series with the first evaporator 232 and the first condenser 231. The first electronic expansion valve 233 can be connected between the first condenser 231 and the first air outlet 222, between the first evaporator 232 and the first condenser 231, or between the first evaporator 232 and the return air port 212 of the compressor 21. The specific connection can be selected according to the actual situation, and the present disclosure does not make specific limitations on this.

[0088] For example, as shown in Figure 12 , the first electronic expansion valve 233 is connected between the first condenser 231 and the first air outlet 222.

[0089] By adjusting the opening degree of the first electronic expansion valve 233, the flow of the first refrigerant in the first refrigerant circulation loop can be adjusted, so that the heat exchange efficiency of the first evaporator 232 and the first condenser 231 can be controlled, which is beneficial to improve the heat exchange efficiency of the first heat exchanger assembly 23, thereby improving the drying efficiency of the clothes dryer 100.

[0090] In some embodiments, referring to Figure 13 , the clothes dryer 100 further includes a first filter screen 7, which is arranged in the first air duct 13 and located at the windward side of the first evaporator 232.

[0091] In this way, when the air in the first drying chamber 11 enters the first air duct 13, part of the lint, hair and other impurities in the air can be filtered out. In this way, the risk of the lint, hair and other impurities winding or adsorbing on the first evaporator 232 and the first condenser 231 to cause the heat exchange efficiency of the first evaporator 232 and the first condenser 231 to decrease can be reduced. In this way, the risk of the clothes dryer 100 having a decreased drying efficiency can be reduced.

[0092] In some embodiments, referring to Figure 10The second heat exchanger assembly 24 comprises a second condenser 241 and a second evaporator 242. The second condenser 241 is connected with the second air outlet end 223. The second evaporator 242 is connected in series with the second condenser 241 and connected with the return air port 212 of the compressor 21 to form a second refrigerant circulation loop.

[0093] As shown in Figure 11 , the second evaporator 242 is arranged at the windward side of the second condenser 241. That is, the air entering the second air duct 14 from the second air outlet 122 of the second drying chamber 12 will pass through the second evaporator 242 and the second condenser 241 in sequence.

[0094] In this way, when drying clothes in the second drying chamber 12, the air in the second air duct 14 will be heated by the second condenser 241 into dry hot air and enter the second drying chamber 12 through the second air inlet 121. Then the dry hot air will take away the moisture on the wet clothes and become warm and humid air. After the warm and humid air enters the second air duct 14 through the second air outlet 122, it will be cooled and the moisture will be condensed under the action of the second evaporator 242, thereby becoming dry cold air. The dry cold air will be heated again into dry hot air when passing through the second condenser 241. In this way, the clothes can be dried.

[0095] On this basis, referring to Figure 12 , the second heat exchanger assembly 24 can further comprise a second electronic expansion valve 243 connected in series with the second evaporator 242 and the second condenser 241. The second electronic expansion valve 243 can be connected between the second condenser 241 and the second air outlet end 223, between the second evaporator 242 and the second condenser 241, or between the second evaporator 242 and the return air port 212 of the compressor 21. The specific connection can be selected according to the actual situation, and the present disclosure does not make specific limitations.

[0096] Exemplarily, as shown in Figure 12 , the second electronic expansion valve 243 is connected between the second condenser 241 and the second air outlet end 223.

[0097] By adjusting the opening degree of the second electronic expansion valve 243, the refrigerant flow in the second refrigerant circulation loop can be adjusted, so that the heat exchange efficiency of the second evaporator 242 and the second condenser 241 can be controlled, which is conducive to improving the heat exchange efficiency of the second heat exchanger assembly 24 and thus improving the drying efficiency of the clothes dryer 100.

[0098] In some embodiments, referring to Figure 13The drying machine 100 further comprises a second filter screen 8, which is arranged in the second air duct 14 and located at the windward side of the second evaporator 242.

[0099] In this way, when the air in the second drying chamber 12 enters the second air duct 14, part of the lint, fluff and other sundries in the air can be filtered out. In this way, the risk of the lint, fluff and other sundries winding or adsorbing on the second evaporator 242 and the second condenser 241 to cause the heat exchange efficiency of the second evaporator 242 and the second condenser 241 to decrease can be reduced. In this way, the risk of the drying efficiency of the drying machine 100 decreasing can be reduced.

[0100] In some embodiments, the drying machine 100 further comprises a start button, through which a user can input a control instruction to control the drying machine 100 to run different working modes to dry clothes.

[0101] For example, the user can input a control instruction through the start button to control the drying machine 100 to dry clothes through the first drying chamber 11, input a control instruction through the start button to control the drying machine 100 to dry clothes through the second drying chamber 12 only, and input a control instruction through the start button to control the drying machine 100 to dry clothes through the first drying chamber 11 and the second drying chamber 12 at the same time.

[0102] It should be noted that the drying machine 100 can further comprise a remote control system, through which a user can remotely start the drying machine 100 and control the drying machine 100 to run different working modes to dry clothes through an app client on a terminal such as a mobile phone or a tablet computer.

[0103] In the description of the present specification, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0104] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope described in the claims.
