Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 to 4 show a single-circulation drying integrated machine, which comprises a box body 1, a drying fan 2, a dehumidifying fan 3, an air inlet 4, a compressor 5, an evaporator 6 and a condenser 7, wherein the drying integrated machine is arranged in a drying room 8, and the evaporator 6 and the condenser 7 are arranged in the box body 1 and divide the box body 1 into three chambers; a dehumidification cavity is formed between the box body 1 and the evaporator 6, a heating cavity is formed between the evaporator 6 and the condenser 7, and a heat collection cavity is formed between the condenser 7 and the box body 1; the air inlet 4 and the dehumidifying fan 3 are arranged on the box body 1 outside the dehumidifying cavity, the air inlet 4 is an air inlet 4 which can be communicated with the inside of the box body 1 and the outside of the drying room 8, and the dehumidifying fan 3 is the dehumidifying fan 3 which is communicated with the inside of the box body 1 and the outside of the drying room 8; the dehumidification cavity and the heating cavity are both communicated with a drying room 8; the heat collection cavity is a closed cavity, one end of the heat collection cavity is communicated with air in the heating cavity through a condenser 7, the other end of the heat collection cavity is communicated with air in a drying room 8 through a drying fan 2, and the drying fan 2 is arranged on a box body 1 on the outer side of the heat collection cavity; through the drive of drying fan 2, the air admission dehumidification chamber in the stoving room 8 heats the chamber, gets into stoving room 8 formation circulation once more after heating through condenser 7.

Dehumidification chamber and heating chamber all communicate stoving room 8 through the top opening, specifically, dehumidification chamber and heating chamber top all are fixed with the grid board, realize and 8 circulation of air in stoving room through the grid.

Drying fan 2 is provided with electric auxiliary heating device 9, electric auxiliary heating device 9 is electric heating pipe, electric heating pipe sets up to set up into the circular shape disc, the size of disc is more than or equal to the installing port of installation drying fan 2, so for drying fan 2 exhaust wind can be covered the heating completely.
