When the dryer operates as a dryer, the second actuator (41) is turned off by the weight of the blocking plate (40). Opening the outlet 13 while descending so that the steam generated during the drying operation can be discharged to the outside through the outlet (13).

Referring to the operation of the present invention configured as described above is as follows.

◈ Dryer Operation ◈

Drying operation is a user puts the vegetables or aquatic products to be dried on the tray (16) in the state placed on the tray 14, and then operate the control panels 27, 28 to operate the drying.

In the initial drying operation, the opening / closing door 35 of the damper 30 is closed by the ON operation of the first actuator 37, the second actuator 41 is turned off, and the discharge port 13 is opened.

That is, as the heater 21 and the blower fan 22 installed in the heater chamber 20 operate, the heated air is supplied to the flow space 6 through the air vent 9, and the heated air 6 And through the flow hole 10 is supplied into the drying chamber (2) (3) inside the drying object in the drying chamber starts to dry.

The steam generated at this time is discharged through the outlet 13.

After the initial drying operation is continued for a set time, the first actuator 37 is turned off by the control of a control device (not shown) and the weight of the weight body 36 installed in the opening / closing door 35 of the damper 30 is reduced. Opening and closing door 35 is opened by the outside air is supplied into the heater chamber 20 through the inlet chamber 32 and the outdoor air induction pipe 24 of the damper 30, the outside air supplied into the heater chamber 20 Is blown by the blowing fan 22 and supplied into the drying chamber (2) (3).

As the outside air is continuously supplied into the drying chamber (2) (3), the steam in the drying chamber is quickly discharged to the outside, the drying of the object to be dried in the process.

◈ Refrigerated, frozen operation ◈

Refrigeration and freezing operation of the present invention is to use a refrigerator or freezer when the dryer is not used.

When the user sets the refrigerating and freezing temperatures of the drying chambers 2 and 3 using the third control panel 29, the compressor 26 operates to compress and discharge the refrigerant, and to output the compressor 26. The three-way valve 50 installed in the operation operates to supply the refrigerant to the first and second refrigerant pipes 7, 8 built in the heat insulating wall 4 of the drying chamber 2, 3.

When the refrigerant is supplied to the refrigerant pipes 7 and 8, the refrigerant passing through the refrigerant pipes 7 and 8 cools the air in the flow space 6 between the inner panel 5 and the heat insulation wall 4. By the rotation of the blower fan 22, low-temperature air present in the flow space 6 is supplied to the drying chambers 2 and 3 to lower the internal temperature of the drying chamber.

When the drying chamber (2) (3) is used as a refrigerator or freezer, the blocking plate 40 is raised by the on-operation of the second actuator 41 to block the discharge port (13).

When the refrigerating or freezing operation is started, the first temperature sensor 100 and the second temperature sensor 101 sense the temperature inside the first drying chamber 2 and the second drying chamber 3, respectively, and supply them to the controller 102. The controller 102 determines whether the internal temperatures of the drying chambers 2 and 3 detected by the respective temperature sensors 100 and 101 are higher or lower than the target temperature set by the user.

As a result of the determination, when the temperature sensed by the temperature sensors 100 and 101 is higher than the target temperature, the three-way valve 50 is kept open, and when the sensing temperature is lower than the target temperature, the controller 102 controls the three-way valve ( The first solenoid valve 57 or the second solenoid valve 58 constituting the 50 is selectively turned off to block the flow of the refrigerant supplied to the first supply pipe 54 or the second supply pipe 56.

Then, when the temperature of the drying chamber is raised again, the control unit 102 again operates the first or second solenoid valves 57 and 58 to turn on the first refrigerant pipe 7 or the second refrigerant pipe 8. The refrigerant is to be supplied to the refrigeration or freezing of the drying chamber (2) (3) is to be made.
