Referring to Figures 1 to 4 the effect of the present invention configured as described above is as follows.

First, the capsule chamber 4 with the door 4 'is installed in the solid chamber to prevent cold air flowing through the solid outlet damper 6 from being directly introduced into the capsule chamber 4, and the solid suction port is provided at the solid suction port. When the damper 5 is installed and the capsule chamber 4 is opened, the cold air is prevented from entering the cooler 3.

In addition, a deodorizer 6 'is attached to the inner wall of the solid in order to remove the smell in the solid room, and a aging pan FM and a ripening heat H for aging the fermented food are installed in the capsule room 4. In addition, inside the capsule chamber 4, a dummy door (TH), which is a high temperature temperature sensor, is installed to control the temperature inside the high temperature, and a solid door switch (SW1) is installed at the hinge portion of the solid door to detect whether the solid door is opened or closed. do.

Meanwhile, in order to open and close the solid inlet damper 5, a relay RL1, a solid inlet damper motor M1, and a solid inlet damper detection switch SW2 for detecting the opening and closing of the damper 5 are installed, and the solid outlet damper is installed. In order to open and close (6), a relay (RL2), a solid outlet damper motor (M2) and a solid outlet damper detection switch (SW3) for detecting the opening and closing of the damper (6) are installed, and to set the temperature in the solid room. Variable resistor VR is used.

In addition, the deodorizer 6 'is controlled by driving the relay RL3, and the aging fan FM and the aging heater H are controlled by driving the relay RL4, wherein each relay RL1 is controlled. The operation of -RL4) is determined by the output of the inverter section 21.

Therefore, when the solid door is opened to store the remaining side dishes or kimchi (fermented food) or to put the kimchi to ferment, the solid door switch (SW1) is turned off so that the input terminal (I1) of the signal input unit 204 in the microcomputer 20 'High' signal is applied to the output terminal O1 of the load driver 205 until the solid inlet damper detection switch SW2 is turned on from off, that is, the signal of the input terminal I2 goes from low to high. Since the 'high' signal is output from the output terminal O1 of the microcomputer 20 until it is changed, the relay RL1 and the solid inlet damper motor M1 are driven to close the solid inlet damper 5 so that the smell of the cooler ( It blocks the inflow to 3).

In addition, the 'high' signal at the output terminal 02 of the microcomputer 20 until the solid-state damper detection switch SW3 is turned off from on, that is, until the signal of the input terminal I3 changes from low to high. Since the relay RL2 and the solid outlet damper motor M2 are driven, the solid outlet damper 6 is also closed, thereby preventing cold air from leaking to the outside.

On the other hand, when the solid door is closed, the solid door switch SW1 is turned on, and thus a 'low' signal is applied to the input terminal I1 of the signal input unit 204, and thus, at the output terminal O3 of the output driver 205. A high 'signal is output to drive the relay RL3 and the deodorizer 6', where the door 4 'of the capsule chamber 4 is closed by the solid door.

In addition, when the relay RL1 for controlling the solid inlet damper motor M1 is driven only by the solid inlet damper detection switch SW2 until the signal goes from high to low, the solid inlet damper 5 is opened. The cold air inside the high temperature is introduced and circulated in the solid chamber. At this time, the internal temperature detecting dummyster TH installed in the capsule chamber 4 detects the temperature in the high temperature and the CPU 201 through the temperature sensing unit 203. The CPU 201 compares the temperature set by the variable resistor VR with the current internal temperature and turns the solid outlet damper 6 on and off according to the result. Always remains close to the set temperature.

On the other hand, when a predetermined input signal for aging kimchi, etc. is input from the key input unit K, the CPU 201 detects this and controls the solid outlet and inlet damper motors M2 and M1, and relays RL2 and RL1. Is turned off to close the solid outlet and inlet dampers 6 and 5, and then the relay RL3 is turned on to drive the deodorizer 6 'so that the smell in the solid is removed.

Since the relay RL4 operates for a set time according to a menu input from the key input unit K, the ripening fan FM and the heater H are driven to ripen kimchi.

When the relay RL4 is turned off after the set time, the CPU 201 detects the temperature in the solid chamber through the temperature sensing dummyster TH and turns on and off the solid outlet and the inlet dampers 6 and 5. The temperature in (4) is maintained at approximately -1 degrees.

In addition, if the switch SW4 is selectively turned on externally while the deodorizer 6 'is being driven, the microcomputer 20 detects this and outputs a' low 'signal at the output terminal O3 to turn on the relay RL3. Since the power applied to the deodorizer 6 'is cut off, driving of the deodorizer 6' is interrupted, and a switch for releasing the ripening of kimchi, etc., is incorporated in the key input unit K. Accordingly, the setting temperature may be changed by adjusting the variable resistor VR.

As described above, according to the present invention, when the fermented foods such as kimchi or the leftovers are stored in the solid of the three-door refrigerator, the smell of the fermented and stored foods can be prevented from spreading to the whole inside of the refrigerator. Food can be kept clean.
