Example 2
A second embodiment of the drying system of the present application will be described with reference to fig. 2. Wherein, fig. 2 is a system diagram of a drying system in the second embodiment of the present invention.
As shown in fig. 2, on the premise of keeping the other structural arrangements unchanged in embodiment 1, the drying system further includes a cascade heat exchanger 22, where the cascade heat exchanger 22 has a first inlet 221, a first outlet 222, a second inlet 223 and a second outlet 224, one air flow channel is formed between the first inlet 221 and the first outlet 222, another air flow channel is formed between the second inlet 223 and the second outlet 224, and the two air flow channels are arranged to intersect with each other, so as to be able to exchange heat in a cross-flow manner. The first inlet 221 communicates with the humid air outlet 211, the first outlet 222 communicates with the inlet of the evaporator 14, the second inlet 223 communicates with the outlet of the evaporator 14, and the second outlet 224 communicates with the inlet of the condenser 12. The specific structural form of the cascade heat exchanger 22 is not limited in the present application, and any heat exchanger that can satisfy the above conditions can be applied to the present application as the cascade heat exchanger 22. For example, a plate-fin heat exchanger or a heat wheel heat exchanger may be used as the cascade heat exchanger 22 of the present application.
According to the orientation shown in fig. 2, the high temperature humid air discharged from the humid air outlet 211 flows into one air flow passage of the cascade heat exchanger 22 through the first inlet 221 of the cascade heat exchanger 22 first, and the low temperature dry air flowing out of the evaporator 14 flows into the other air flow passage of the cascade heat exchanger 22 through the second inlet 223 of the cascade heat exchanger 22, and the two air flows into the air flow passage are heat-exchanged, so that the temperature of the high temperature humid air is lowered and the temperature of the low temperature dry air is raised at the same time (the process is equivalent heat exchange).

Meanwhile, since the low-temperature dry air flowing out of the evaporator 14 exchanges heat with the wet air, the temperature of the air entering the condenser 12 is higher than that of the air directly entering the condenser 12 without the overlapping heat exchanger 22, and thus the temperature of the air discharged from the condenser 12 and entering the drying chamber 21 again is higher than that of the air without the overlapping heat exchanger 22, and therefore, the arrangement of the overlapping heat exchanger 22 also increases the temperature of the air entering the drying chamber 21, accordingly, the drying speed of the clothes is increased, the drying efficiency is further improved, and the energy consumption is further reduced.

The suspended parts can be arranged along the horizontal plane in a U shape or an S shape, and can also be arranged in multiple layers along the height direction, and each layer is arranged in a U shape or an S shape.
According to the orientation shown in fig. 2, the refrigerant discharged from the condenser 12 flows to the throttling element 13 after passing through the suspended second pipe segment 152 and the first pipe segment 151 coiled inside the water pan 31 in sequence. At the same time, part of the condensation water produced by the evaporator 14 drops onto the second suspended pipe section 152 during the dropping process and then flows into the water pan 31.
Through suspending second pipe section 152 between evaporimeter 14 and water collector 31, this application can also utilize the comdenstion water to drip when whereabouts and realize the wet film heat transfer on unsettled refrigerant pipe 15, further promotes the temperature drop effect of refrigerant. Through second tube section 152 be the U type or the S type is arranged, can improve the heat transfer effect of wet membrane heat transfer.

The utility model discloses do not deviate under the prerequisite of principle, technical personnel in the field can adjust the mode of setting up to the aforesaid, so that the utility model discloses can be applicable to more specific application scene.
For example, in an alternative embodiment, the arrangement of the evaporator 14, the condenser 12 and the fan 24 is not constant, and those skilled in the art can make modifications to the arrangement of the above components without departing from the principles of the present application, provided that the air circulation loop can be formed. For example, one or more of the evaporator 14, the condenser 12, and the fan 24 may also be disposed directly inside the air duct 25.
As another example, in another alternative embodiment, two modifications of example 2 may be selectively chosen by one skilled in the art to suit a particular application scenario. For example, only the cascade heat exchanger 22 can be added or only the second pipe section 152 can be provided on the basis of embodiment 1.
