FIG. 5 is a setting state diagram of the refrigerator of the present invention.
(EVA) is installed, the inside of the Ever 51 is configured so that it can be used as a freezing chamber, and a container 56 having a constant volume can be placed on a lower plate 52 configured as a heat generating plate equipped with a heater H below. The structure is as follows, and a thermistor 53 is installed at 1/2 the height of the refrigerator.The kimchi is made using the atmospheric principle that cold air is transmitted from above to below and hot air is transmitted from below to above. It was constructed so that it could be stored after it generated heat.

In the present invention configured as described above, when the input power AC is applied via the input changeover switch _S1 , the rectifier circuit 1 configured on the secondary side of the transformer _T1
A more constant DC power supply E ₁ , E ₂ , _{E 3} , F ₁ , F ₂ will be supplied to each part of the refrigerator circuit. By outputting a buzzer sound to the speaker SP, the user is informed that normal power has been input. All such operations are performed by the read-only memory programmed inside the microcomputer 10. Controlled by ROM status signals. Thereafter, the clock drive unit 2 causes the display unit 5 to output a status signal for time via the drivers 3 and 4 in accordance with the programmed order.
0, the current time can be known, and a normal state that can be controlled by the key selection section 30 is maintained. Therefore, the alarm function can be controlled by the keys _K1 to _K7 of the key selection unit 30, and the user can reserve a time in advance to check the fermentation status of kimchi and do other work. Then, at the scheduled time, the speaker SP is transmitted via the melody element 6.
It will be output to .

Then, when the fermentation key of the key selection unit 30 is pressed, the voltage is applied to the terminal _P15 of the microcomputer 10, so a buzzer sound is displayed on the speaker SP from the oscillation circuit 2 via the output terminal _P5 , and at the same time, the driver 3, 4 to the display section 5
, the basic fermentation time Hx is displayed and the light emitting diode LED ₁ is lit. Therefore, the basic fermentation time Hx
Kimchi is produced by the amount of heat generated through a heat generating plate composed of a constant area N (m ² ) in which a constant capacity (W) of a heater H is housed in a mechanism having a constant internal volume L (). If kimchi is initially kept in a fermented state in container K(), kimchi will be fermented during basic fermentation time Hx. That is, when kimchi is placed in a container 56 having a constant internal volume as shown in FIG. 5 and placed on the lower plate 52, the heater H is heated and generates heat by the circuit shown in FIG. may be the same as diagram A in FIG. In other words, the fever state at this time is
The heater H is heated for a period of T ₁ to heat the contents of the container 56, and is shut off for a period of T ₄ to prevent a rapid rise in temperature and overheating of the refrigerator. By repeating this operation, sufficient heat is generated in the container 56. It will be transmitted.

When the refrigerator is heated like this, 1/2 of the refrigerator
It is sensed by a thermistor 53 installed at the height and compared with the fermentation set temperature. When the temperature inside the refrigerator is higher than the set temperature, the compressor C is operated, and when it is lower than the set temperature, the heater H is operated and the temperature is kept constant. The set temperature will be maintained.

This is because the resistance value of _the thermistor ₅₃ of the _fermentation and storage sensing section ₄₀ in FIG. When the amplification degree is determined by the power supply distributed by R ₅ and applied to the microcomputer 10, a relative signal amplified from the variable resistor VR ₂ of the reference temperature setting section 45 via the operational amplifier 8 is transmitted to the microcomputer 10. 10, the fermentation and storage sensing section 40 is controlled by a microcomputer;
The compressor drive unit 14 and the heater drive unit 15 are controlled according to the values compared by the reference temperature setting unit 45.
The compressor C and heater H are operated by controlling the triacs TD ₁ and TD ₂ via the

When the fermentation operation is completed in this way, the transistor Q ₂ is connected to the output terminal P ₇ of the microcomputer 10.
is made conductive, the melody element 6 operates, and the output is output to the speaker SP, allowing the user to check the fermentation status. The fermentation status can be confirmed by outputting the melodic sound as described above, and after the set time has elapsed, the refrigerator automatically functions as a storage refrigerator. At this time, the light emitting diode LED ₂
The microcomputer 10 compares the temperature of the reference temperature setting section 45 and the temperature detected by the fermentation and storage sensing section 40, and only the compressor C is driven as shown in Fig. 3B. Therefore, since cold air is supplied through the Ever 51 shown in FIG. 5, the temperature at which the fermentation of kimchi is stopped (0° C. to -5° C.), that is, the kimchi is maintained at a freezing temperature. Therefore, when driving a normal refrigerator, the microcomputer 10 compares the sensing signals of the reference temperature setting section 45 and the refrigeration temperature setting section 55, which is composed of resistors R ₉ and R ₁₀ and variable resistor VR ₃ , and sets the compressor drive section. Triack via 14
By controlling TD ₁ , the compressor C will be driven like a normal refrigerator.
