Embodiment 1

[0041] First refer to figure 2 , the first embodiment of the drying system of the present invention will be described. in, figure 2 It is a system diagram of the drying system in the first embodiment of the present invention.

[0042] As mentioned in the background technology, in the existing drying system, as the moisture content of the clothes in the drying chamber gradually decreases, the relative humidity in the drying chamber is also getting smaller and smaller, and the air heated by the condenser is in the drying chamber The lowering range of the medium temperature also decreases, and the temperature of the air entering the evaporator and condenser continues to rise, which leads to the gradual weakening of the dehumidification capacity of the evaporator, and the dehumidification effect is getting worse, which results in longer drying time for clothes and lower power consumption of the system. is also increasing.

[0043] Such as figure 2 As shown, in order to solv...

Embodiment 2

[0060] Refer below image 3 , to describe the second embodiment of the drying system of the present application. in, image 3 It is a system diagram of the drying system in the second embodiment of the present invention.

[0061] Such as image 3As shown, under the premise of keeping other structural settings unchanged in Embodiment 1, the drying system further includes a cascade heat exchanger 22, and the cascade heat exchanger 22 has a first inlet 221, a first outlet 222, a second inlet 223 and the second outlet 224, an air passage is formed between the first inlet 221 and the first outlet 222, another air passage is formed between the second inlet 223 and the second outlet 224, and the two air passages are intersected with each other , enabling cross-exchange of heat. The first inlet 221 communicates with the wet air outlet 211, the first outlet 222 communicates with the air inlet 2311 of the gas-liquid heat exchanger 23, the second inlet 223 communicates with the outle...
