In the following description, for the purposes of explanation, details are set forth in order to provide a thorough understanding of the present application. It should be apparent to those skilled in the art that the present application can be practiced without the specific details presented herein. In other instances, well-known structures and processes are not described in detail in order to avoid obscuring the present application. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.
[0042] The embodiments of the present application provide a drying channel assembly applied to a clothes dryer, which can be a drying device only with drying function, or a washing and drying integrated device with both washing and drying functions. For example, please refer to Figure 1 , Figure 1The structure of the clothes dryer is shown in the schematic view provided by the embodiments of the present application. The clothes dryer 10 comprises a drying drum 100 and a drying duct assembly 200. The drying duct assembly 200 comprises a drying air duct 210 and a cooling structure 220.
[0043] The drying air duct 210 is adapted to be connected with the drying drum 100 to form a circulating air cavity 211, and the circulating air cavity 211 is provided with an air outlet 212 and an air inlet 213 communicating with the outside. The cooling structure 220 forms a mixing cavity 224 with a first air inlet 221, a second air inlet 222 and a moisture outlet 223. The second air inlet 222 communicates with the air outlet 212 to suck in the hot and humid air, and the first air inlet 221 communicates with the outside to suck in the outside air. The hot and humid air and the outside air are mixed in the mixing cavity 224 and then discharged through the moisture outlet 223.
[0044] It should be noted that air doors are arranged at the air outlet 212 and the air inlet 213, and the air doors are rotatable to have two states of opening and closing. The clothes dryer 10 further comprises a heat pump system 300, which comprises a compressor 310, an evaporator 320 and a condenser 330. In the actual application, the hot and humid air in the drying drum 100 flows into the drying air duct 210, is first cooled by the evaporator 320, and then dried and heated by the condenser 330, so as to form dry hot air and flow back into the drying drum 100 to evaporate and remove the moisture in the clothes, and the process is repeated to gradually dry the clothes.
[0045] When the air outlet 212 and the air inlet 213 on the circulating air cavity 211 are both in the open state, the hot and humid air in the drying drum 100 flows into the drying air duct 210, the second air inlet 222 sucks part of the hot and humid air flowing to the air outlet 212 into the mixing cavity 224, and the hot and humid air is mixed with the outside air sucked in by the first air inlet 221 in the mixing cavity 224 and then discharged to the outside through the moisture outlet 223. Since the hot and humid air flows out of the circulating air cavity 211 through the air outlet 212, the pressure near the air inlet 213 in the circulating air cavity 211 is lower than the outside pressure, so the dry air in the outside will flow into the circulating air cavity 211 through the air inlet 213 and flow back into the drying drum 100.
[0046] It can be understood that, limited by the condensation efficiency of the condenser 330, when the humidity of the air in the early circulation air cavity 211 is relatively large, if only relying on the condenser 330 to dehumidify and dry the hot and humid air, a relatively long time is required, which will result in a relatively long drying time. The drying duct assembly 200 provided by the application can adjust the air outlet 212 and the air inlet 213 to an open state in the early drying stage, so that the circulation air cavity 211 exchanges air with the outside, realizes rapid dehumidification of the air in the circulation air cavity 211 and the drying drum 100, and thus improves the drying efficiency of the clothes dryer 10. Preferably, the air outlet 212, the evaporator 320, the condenser 330 and the air inlet 213 are sequentially arranged in the circulation air cavity 211 along the air flow direction.
[0047] On the other hand, since the temperature of the outside air is relatively low, after the hot and humid air is mixed with the outside air in the mixing cavity 224, heat exchange is performed between the two, forming relatively low-temperature mixed gas which is then discharged to the outside through the dehumidifying port 223.
[0048] The drying duct assembly 200 provided by the application can cool the relatively high-temperature hot and humid gas in the mixing cavity 224 before discharging it to the outside, which can avoid the direct discharge of high-temperature hot and humid air to cause the aging of the components of the clothes dryer 10 and prevent the service life of the equipment from being shortened.
[0049] Optionally, the mixing cavity 224 includes a first inner wall 2241 and a second inner wall 2242 oppositely arranged in a first direction, and a third inner wall 2243 and a fourth inner wall 2244 oppositely arranged in a second direction, the first direction being different from the second direction; the second suction port 222 is arranged on the first inner wall 2241, the dehumidifying port 223 is arranged on the third inner wall 2243, and the first suction port 221 is arranged on the second inner wall 2242 or the fourth inner wall 2244.
[0050] For example, as shown in Figure 1 , the first suction port 221 is arranged on the fourth inner wall 2244. In other embodiments, please refer to Figure 2 , Figure 2 for a structural schematic view of the cooling structure provided by the application. The first suction port 221 is arranged on the third inner wall 2243, and the first direction is perpendicular to the second direction.
[0051] In some embodiments, please refer to Figure 3 , Figure 3Another structure diagram of the cooling structure provided by the embodiment of the present application is also provided. A stirring member 225 can be arranged in the mixing cavity 224 to improve the mixing efficiency of the hot and humid air and the air from the outside in the mixing cavity 224 by stirring. The stirring member 225 can be a fan or other stirring mechanism. Alternatively, a plurality of air guide grooves (not shown) can be arranged on the inner wall of the mixing cavity 224. The air flows out in multiple directions after being dispersed by the grooves, thus further improving the mixing efficiency of the air in the mixing cavity 224.
[0052] To further improve the air exchange efficiency between the circulating air cavity 211 and the outside, a Venturi tube can be used to improve the air flow rate in the cooling mechanism. For example, as shown in Figure 4 , Figure 4 Another structure diagram of the cooling structure provided by the embodiment of the present application is provided. The cooling structure 220 includes a first Venturi tube 226 and a second Venturi tube 227. The air inlet end of the first Venturi tube 226 forms a first suction port 221, and the air outlet end of the first Venturi tube 226 is in communication with the mixing cavity 224. The air inlet end of the second Venturi tube 227 forms a second suction port 222, and the air outlet end of the second Venturi tube 227 is in communication with the mixing cavity 224. In some other embodiments, the cooling structure 220 can include only the first Venturi tube 226 or the second Venturi tube 227.
[0053] To improve the condensation efficiency of the hot and humid air in the circulating air cavity 211 and shorten the drying time, as shown in Figure 1 , an auxiliary refrigeration member 228 can be arranged in the circulating air cavity 211 of the drying air duct 210. The auxiliary refrigeration member 228 and the condenser 330 are arranged in the circulating air cavity 211 in sequence along the air flow direction. The auxiliary refrigeration member 228 can be an electromagnetic refrigeration piece, a capillary refrigeration mechanism between the compressor 310 and the evaporator 320, a cold water circulation refrigeration device or other refrigeration mechanism. Alternatively, the auxiliary refrigeration member 228 can be arranged between the drying barrel 100 and the evaporator 320 or between the evaporator 320 and the condenser 330.
[0054] To further reduce the temperature of the hot and humid air discharged from the dehumidifying port 223, the auxiliary refrigeration member 228 can be reused to refrigerate the mixed air in the mixing cavity 224. For example, as shown in Figure 1As shown, the circulating air cavity 211 includes a refrigeration section 2111 provided with an auxiliary refrigeration device 228, and the refrigeration section 2111 is arranged adjacent to the mixing cavity 224. In this way, the cold energy radiated by the auxiliary refrigeration device 228 can be used to cool the mixed gas in the mixing cavity 224, so that the temperature of the air discharged from the dehumidifying port 223 is further reduced, thereby avoiding the direct discharge of high-temperature humid air to cause the aging of the components of the clothes dryer 10 and prevent the service life of the equipment from being shortened. In addition, a heat-conducting material can be filled between the refrigeration section 2111 and the mixing cavity 224. In this way, the good heat conduction performance of the heat-conducting material is used to make more cold energy radiated by the auxiliary refrigeration device 228 enter the mixing cavity 224, so as to improve the cooling efficiency of the mixed gas. The heat-conducting material can be a heat-conducting metal such as aluminum, copper or the like, and can also be a ceramic, glass or other material with good heat conduction performance.
[0055] In some embodiments, to prevent the mixing cavity 224 from being contaminated, a filter (not shown) can also be arranged at the first suction port 221. In this way, the external air sucked in by the first suction port 221 can be filtered by the filter, so as to prevent dust, lint and other contaminants carried in the air from entering the mixing cavity 224 and prevent bacteria from breeding in the mixing cavity 224 to produce odor. In addition, a filter can also be arranged at the air inlet 213 to filter the external air entering the circulating air duct, so as to prevent contaminants from entering the drying barrel 100 and affecting the cleanliness of the clothes.
[0056] The drying duct assembly 200 provided by the embodiments of the present application can make the high-temperature humid gas first be cooled in the mixing cavity 224 before being discharged to the outside, thereby avoiding the direct discharge of high-temperature humid air to cause the aging of the components of the clothes dryer 10 and prevent the service life of the equipment from being shortened.
[0057] The embodiments of the present application also provide a clothes dryer 10, such as Figure 1 and Figure 5 , Figure 5 Another structural schematic diagram of the clothes dryer provided by the embodiments of the present application. The clothes dryer 10 includes a cabinet 400, a drying barrel 100, a drying duct assembly 200 in any of the above embodiments and a heat pump system 300.
[0058] Among them, the drying barrel 100, the drying duct assembly 200 and the heat pump system 300 are all installed in the cabinet 400, the drying duct assembly 200 is connected with the drying barrel 100, and the heat pump system 300 is installed in the drying duct assembly 200. The cabinet 400 usually also has an electric control system, a drainage assembly of the clothes dryer 10, and for a washing-drying integrated clothes dryer 10, the cabinet 400 also has a water box, a drainage assembly of washing water and other components.
[0059] It can be understood that the drying channel assembly 200 discharges the hot and humid air to the cabinet 400 or outside the clothes dryer 10 through the moisture discharge port 223, the cooling mechanism of the present application discharges the hot and humid air after cooling, which can avoid the negative effects of the high temperature of the hot and humid air on the environment or the components of the clothes dryer 10.
[0060] The clothes dryer 10 provided by the embodiments of the present application adds the cooling mechanism at the air outlet 212 on the circulating air path, so that the hot and humid gas with high temperature can be cooled in the mixing chamber 224 before being discharged to the outside, which can avoid the direct discharge of the hot and humid air with high temperature to cause the aging of the components of the clothes dryer 10 and prevent the service life of the equipment from being shortened.
[0061] The above describes the drying channel assembly and the clothes dryer provided by the embodiments of the present application in detail, and the principles and implementation manners of the present application are described by applying specific examples; the above description of the embodiments is only used to help understand the method of the present application and the core idea thereof; meanwhile, for those skilled in the art, the specific implementation manners and application ranges will be changed according to the idea of the present application, and in summary, the content of the specification should not be understood as a limitation of the present application.
