[0032] Based on the above structure, when using the water-based paint drying room of the utility model, the user opens the door body 16 and places the objects sprayed with water-based paint in the drying chamber 112 and then closes the door body 16. The compressor 2 runs the pressurized medium to increase the temperature of the medium to form a high-temperature and high-pressure medium. The high-temperature and high-pressure medium is discharged from the exhaust end of the compressor 2 and enters the heat exchange plate 3 from the inlet end of the heat exchange plate 3, and dissipates heat from the outside of the heat exchange plate 3 to be transferred to the air around the heat exchange plate 3. At the same time, the first fan 5 located on one side of the heat exchange plate 3 rotates to guide the heated air around the heat exchange plate 3 to the first filter plate 15 on the other side for fine filtration, thereby ensuring that pure hot air flows into the drying chamber 112 and dries the objects coated with water-based paint, thereby avoiding impurities in the air affecting the surface quality of the water-based paint after drying.

[0033] Of course, the air after drying the water-based paint article enters the return air chamber 111 under the suction action of the first fan 5 to be heated.

[0034] It should be noted that the compressor 2 is connected to the heat exchange plate 3 located in the return air chamber 111 through a pipeline, and a high-temperature and high-pressure medium is supplied to the heat exchange plate 3 through the pipeline.

[0035] Specifically, the filter assembly further includes a second filter plate 141 . An air vent 14 connected to the drying chamber 11 and used for air intake is provided on the left side of the room body 1 . The second filter plate 141 is arranged on the air vent 14 and located in the drying chamber 11 .

[0036] In the above structure, when external air enters the drying chamber 11 from the air outlet, the second filter plate 141 will filter the air once, and when the air flows back in the return air chamber 111 and the drying chamber 112, the first filter plate 15 will filter the air in the drying chamber 11 for a second time. Of course, each time the air flows back in the return air chamber 111 and the drying chamber 112, it will be carefully filtered by the first filter plate 15 to prevent impurities in the air from affecting the surface quality of the water-based paint after drying.

[0037] Specifically, the heat exchange plate 3 includes a plurality of fins and heat release pipes passing through the plurality of fins.

[0038] Furthermore, the new water-based paint drying room also includes an evaporator 4, which includes a first evaporation plate 41 and a second evaporation plate 42.

Among them, three first fans 5 are arranged side by side on one side of the heat exchange plate 3.

[0040] Therefore, the medium flowing through the second evaporator plate 42 can absorb the heat of the air in the return air chamber 111, and the medium flowing through the first evaporator plate 41 located on the top of the room body 1 can absorb the heat of the external air through the rotation of the second fan 51, and is gathered at the outlet of the first evaporator plate 41 and the second evaporator plate 42 to enter the compressor 2 from the suction end of the compressor 2 for pressurization and temperature increase.

[0041] Furthermore, the novel water-based paint drying room also includes a liquid storage tank 6 , the inlet of the liquid storage tank 6 is connected to the outlet end of the heat exchange plate 3 , and the outlet of the liquid storage tank 6 is connected to the inlet of the first evaporation plate 41 and the second evaporation plate 42 .

[0042] Specifically, an expansion valve 31 is further provided between the heat exchange plate 3 and the liquid storage tank 6 , one end of the expansion valve 31 is communicated with the outlet end of the heat exchange plate 3 , and the other end thereof is communicated with the inlet end of the liquid storage tank 6 .

[0043] Among them, the partition 12 is arranged in the middle position of the drying chamber 11, and one end of the partition 12 forms an air inlet 113 with the inner wall of the drying chamber 11, and the other end forms a return air outlet 114 with the inner wall of the drying chamber 11. The air inlet 113 and the return air outlet 114 both connect the return air chamber 111 with the drying chamber 112.

[0044] Furthermore, the drying chamber 11 is provided with an air guide block 13 , and four air guide blocks 13 are provided, which are respectively arranged on both sides of the top of the drying chamber 11 and both sides of the bottom of the drying chamber 11 ; the air guide block 13 is provided with a curved surface 131 for guiding air.

[0045] Specifically, after the first fan 5 guides the air around the heat exchange plate 3 to the first filter plate 15 for filtration, the air flows into the drying chamber 112 through the air inlet 113 under the action of the curved surface 131 of the air guide block 13 located on one side of the top of the drying chamber 11, and then dries the items in the drying chamber 112 under the action of the curved surface 131 of the air guide block 13 located on the other side of the bottom of the drying chamber 11. At the same time, it flows to the air guide block 13 on the other side of the bottom of the drying chamber 11, and flows to the air guide block 13 on the other side of the top of the drying chamber 11 through the return air port 114 under the action of the curved surface 131, and enters the suction end of the first fan 5 under the action of the curved surface 131, enters the circulation reflux after heating, so as to dry the items in the drying chamber 112.

[0046] Of course, the air outlet 14 is provided with an air door 142 located outside the room body 1 .
