And the other side of the upper diaphragm is a dry main body formed with a side diaphragm for partitioning with the machine room; a suction fan provided on the air passage on the other side of the upper diaphragm to suck the wet air present in the drying chamber; a heat exchange inlet formed on the surface of the side diaphragm in communication with the air inlet of the heat exchanger to guide wet air in the drying chamber to be introduced into the heat exchanger when the suction fan is operated; a humidity sensor installed on one side of the drying chamber to measure humidity in the drying chamber; a heat exchanger provided in the machine room, for dehumidifying and exchanging the humid air introduced through the heat exchange inlet to a set temperature when the suction fan is operated; a plurality of wind direction plates installed horizontally and spaced apart from each other to set a supply direction while dividing the amount of air supplied through the air supply port at one side of the drying chamber; It is characterized in that it is installed on the rear side of the wind direction plate and is provided to rotate in the left and right directions, and it is characterized in that it consists of an air diffusion unit provided with an air diffusion fan to diffuse the air introduced into the drying chamber through the wind direction plate.

However, since the above techniques include a configuration for dehumidifying the humidity increased in the air by hot air, there is a problem in that a configuration of a dehumidifying device to reduce the humidity must be included.

In addition, the air supplied to the drying chamber is intensively delivered only to the drying shelf arranged on the air supply side and hardly supplied to the drying shelf arranged on the air exhaust side, so that the object to be dried loaded on the air supply side drying shelf is transferred to the air exhaust side drying shelf. There was a problem of drying in a relatively short period of time compared to the object loaded in the air conditioner. To solve this problem, in the process of drying, the dentures of the drying shelf arranged on the air supply side and the dentures of the drying shelf arranged on the air exhaust side were exchanged, a cumbersome work process. There is a problem that needs to be done.
