the air inlet 13 is provided with a first air inlet 131, and the first air inlet 131 is respectively communicated with the cavity 112 and a second air outlet which is arranged in the drying cylinder 2 of the clothes dryer 100 and used for discharging damp and hot air so as to be introduced into the damp and hot air; the first air outlet 111 may communicate with the external environment to exhaust air;

the first air outlet 111 is communicated with the external environment of the clothes dryer body 100 in a one-way manner, and one end of the first air outlet 111 far away from the cavity 112 is provided with a one-way valve, so that the air in the cavity 112 can be discharged to the external environment of the device body 1 through the one-way valve; or an exhaust valve is arranged at the first air outlet 111, and when the humidity and the temperature in the cavity 112 meet the exhaust standard, the exhaust valve is opened to exhaust;

after the clothes dryer body 100 is started, the clothes dryer body 100 executes a drying program, the heater 4 of the clothes dryer body 100 heats air entering the clothes drying cylinder 2, after the heated hot air enters the clothes drying cylinder 2, moisture contained in clothes held in the clothes drying cylinder 2 is heated and evaporated to form air flow containing water molecules, under the guidance of the fan 5 of the clothes dryer body 100, the air flow containing the water molecules is mixed into the hot air in the clothes drying cylinder 2, and the hot and humid air with higher temperature is discharged from the second air outlet; the damp and hot air discharged from the second air outlet enters the cavity 112 of the device body 1 through the first air inlet 131 of the air inlet 13, the cooling medium in the cooling element 12 absorbs heat of the damp and hot air, so that moisture in the damp and hot air is condensed to form condensed water, the condensed water is separated from the damp and hot air, moisture in the damp and hot air is removed, and dry air is separated, and the cooled dry air is discharged from the first air outlet 111 to the environment outside the clothes dryer body 100, so that the influence on the humidity and temperature of the environment outside the clothes dryer body 100 is reduced. Specifically, the dryer body 100 performs the drying process, the temperature of the air discharged from the hot and humid air discharged from the second air outlet is relatively high, and after the hot and humid air enters the cavity 112, the cooling member 12 absorbs the heat of the hot and humid air to achieve cooling. The temperature and humidity of the air discharged into the external environment of the dryer body 100 are reduced compared to the humidity of the humid air, thereby reducing the environmental pollution. Further, the temperature of the dry air discharged from the dryer body 100 can be controlled by limiting the heat absorbing performance of the cooling member 12, for example, the temperature of the dry air discharged from the dryer body 100 can be controlled to be slightly lower than the room temperature.

Specifically, after the drying program is started in the clothes dryer body 100, the hot and humid air with a higher temperature generated in the drying drum 2 enters the cavity 112 and then enters the second channel 122, the cooling water enters the first channel 121 and absorbs the heat on the heat conducting fins 123 in time to absorb the heat of the hot and humid air, so that the hot and humid air is cooled, the moisture contained in the hot and humid air in the cooling process is condensed to form liquid water, and the liquid water is separated from the hot and humid air to obtain the air after cooling and dehumidification.

In one embodiment, the second channel 122 is in communication with the first inlet 131 and the drain 117, respectively. When the cooling portion and the second passage 122 are respectively located in two relatively independent spaces, the first air inlet 131 and the drain opening 117 are both located in the space where the second passage 122 is located.

In addition, the fins 124 or the ejector pins form the second channel 122, when the cooling portion is located above, or on the left or right of the second channel 122, the downward side of the second channel 122 is open, and the condensed water formed during the cooling process of the moist hot air in the second channel 122 can be discharged in time. The fins 124 or the pins are made of metal, so that the second channel 122 has good heat conductivity, and can dissipate the temperature of the hot and humid air in time, thereby accelerating the speed of dehumidifying the hot and humid air. Further, the cooling member 12 is a copper member or an aluminum member. The heat of the hot and humid air in the second channel 122 is not only transferred to the heat-conducting fins 123, but also transferred to the cooling portion after being transferred to the heat-conducting fins or the heat-conducting pins, so as to accelerate the cooling speed of the hot and humid air.

In an embodiment, the second channel 122 is located below the cooling portion, and the condensed water formed by cooling the moist air in the second channel 122 falls downward under its own weight without contacting the heat-conducting plate 123, so as to prevent the heat-conducting plate 123 from absorbing the heat of the moist air. Further, the drain port 117 is provided at a position corresponding to a lower portion of the second passage 122 on the housing 11. Due to the guiding effect of the gravity of the condensed water, the condensed water finally drops to the inner wall of the bottom of the housing 11, and the water outlet 117 is disposed at a position on the housing 11 corresponding to the position below the second channel 122, which is beneficial to quickly discharging the condensed water. Further, the second channel 122 is opened toward one side of the drain opening 117, so as to timely drain the condensed water generated by the second channel 122, thereby preventing the humidity of the second channel 122 from increasing due to the accumulated condensed water, which is not beneficial to dehumidification.

In one embodiment, an abutment 1110 is provided within the housing 11. The first channels 121 of the cooling member 12 are disposed above the plurality of second channels 122, and one end of each of the second channels 122 is separated from the first channel 121 by a heat-conducting fin 123. The heat-conductive sheet 123 abuts against the abutting portion 1110 to form a structure of a partition plate that divides the cavity 112 into two regions. The cavity 112 is divided into two mutually independent areas, the first channel 121 and the second channel 122 are respectively positioned in the two mutually independent areas in the cavity 112, so that air entering the cavity 112 is prevented from directly contacting the first channel 121 to be condensed to form condensed water, the condensed water falls onto the outer wall of the second channel 122, the humidity of the environment around the second channel 122 is increased, and the formation of dry air is not facilitated; in addition, the condensed water falling from the first channel 121 to the outer wall of the second channel 122 adheres to the outer surface of the second channel 122, which hinders the heat conduction of the second channel 122 and is not beneficial for the second channel 122 to absorb the heat of the damp and hot air.
