[0025] As a preferred embodiment, further, the dehumidification mechanism 5 includes a base 51 installed on the right side of the bottom of the inner cavity of the air-conditioning box 1, a second motor 52 is installed in the inner cavity of the base 51, a turntable 53 is installed at the output end of the second motor 52, a mesh tube 54 is vertically installed on the top of the turntable 53, the mesh tube 54 is breathable, a cross bar 55 is horizontally installed on the top of the mesh tube 54, an outer tube 56 is vertically installed on the outer side of the upper surface of the base 51, and the top of the left side wall of the outer tube 56 is connected to the front end valve 25 through a pipeline, and two front-to-back symmetrical heaters 57 are installed on the inner wall of the outer tube 56, and the gas entering the outer tube 56 is heated by the heater 57, and the top of the outer tube 56 is connected to the upper cover 58 by a hinge.

[0026] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0027] Step 1: The compressor 26 delivers high-temperature and high-pressure refrigerant to the heat dissipation pipe 222. The heat dissipation pipe 222 releases heat to the outside and then passes through the expansion valve 23 to throttle and reduce pressure. When the refrigerant passes through the heat absorption pipe 212, the heat absorption pipe 212 absorbs heat. Therefore, the cooling box 211 cools the airflow and the heating box 221 heats the airflow. Step 2: Under the suction of the negative pressure fan 214, the external air passes through the gaps in the blades 42 and enters the heating box 221 to heat the air. When the air enters the cooling box 211, the air is cooled and the water vapor is liquefied. The accumulated water flows along the inclined surface of the first partition plate 213 into the water receiving tank 3 to achieve air dehumidification. Step 3: The first motor 452 drives the roller 453 to rotate, and the inclined surface on the guide groove 454 can squeeze the plug block 457 to the left. When the plug block 457 is in the straight groove of the guide groove 454, the plug block 457 remains stationary. When the plug block 457 moves to the reverse inclined surface on the other side, the inclined surface squeezes the plug block 457 to the right. Therefore, the rack 456 is repeatedly moved left and right intermittently. Under the transmission condition of the rack 456 and the gear 43, the blade 42 swings left and right intermittently, and the blade 42 changes the air intake direction, expands the air intake range, and thus improves the air dehumidification efficiency. Step 4, open the front valve 25, hang the items to be dehumidified on the horizontal bar 55, or put them on the turntable 53, turn on the heater 57 to heat up, and the second motor 52 drives the turntable 53 to rotate. The items are fully heated, and the gas enters from the bottom of the outer tube 56. The moisture of the items evaporates into the gas when they are heated, and the gas carrying moisture enters the heating box 221. The gas is heated again, and the cooling box 211 cools the gas again. The water vapor liquefies and forms water droplets to dehumidify the items. Therefore, the damp items can be dried.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
