があった。2. Description of the Related Art Some recent refrigerators include a refrigerator room, a vegetable room, and a freezing room arranged from the top. In the case of this refrigerator, one evaporator was provided behind the freezing room, and the freezing room, the refrigerator room, and the vegetable room were cooled by the evaporator. As shown in FIG. 10, the compressor provided at the bottom of the refrigerator is turned off when the temperature of the freezer compartment sensor drops to a preset off temperature with respect to the set temperature in the refrigerator, and the freezer compartment sensor temperature rises to the on temperature. Then, it turned ON, and the temperature inside the refrigerator was kept at the set temperature on average. In the above configuration, when the temperature of the room where the refrigerator is placed (hereinafter referred to as the outside air temperature) is low, the difference between the outside air temperature and the inside temperature of the refrigerator is small, so it is difficult for the cold heat of the freezing room and the evaporator to escape to the outside air. In addition, the rate of cold heat leakage to the vegetable room increases. Because of this, the temperature of the walls and bottom of the vegetable room will drop due to the effects of cold,
There is a problem that the stored food freezes or causes low-temperature damage.

ぎを防止する制御方法であった。In order to solve this problem, a control method has been considered in which a heater for preventing supercooling is provided on the wall surface of the vegetable room, and power is supplied when the compressor is turned off. FIG. 11 shows the operation timing of the supercooling prevention heater and the compressor and the temperature change of the freezer compartment sensor when the outside air temperature is normal (for example, 14 ° C.) by this control method. Compressor is O
When the FF is turned on, the supercooling prevention heater is turned on, and when the compressor is turned on, the heater is turned off. When the outside temperature drops below normal,
Since the amount of cold heat leaking out of the refrigerator is small and the temperature in the refrigerator is hard to increase, the OFF time of the compressor becomes longer as shown in FIG. 12 and the energizing time of the supercooling prevention heater is extended. The control method was to prevent the vegetable room from getting too cold in accordance with changes.

を防止できるものではなかった。However, it is not suitable for a refrigerator having a function of adjusting the internal temperature of the refrigerator with a dial or the like (for example, setting to high, medium, or low). FIG. 13 shows the operation timing of the supercooling prevention heater, the compressor, and the freezer compartment sensor temperature change when the refrigerator having the function of adjusting the inside temperature of the refrigerator with the dial is adjusted to the medium setting. When the cooling capacity is adjusted to the maximum (hereinafter referred to as a strong setting), the temperatures of the freezing compartment and the evaporator are extremely low, and the vegetable compartment tends to be too cold. Therefore, it is desired to increase the energizing time of the supercooling prevention heater. However, as shown in FIG. 14, when the temperature is set to the high setting, the temperature inside the refrigerator is low. Compressor O
The N time is long and the OFF time is short. Therefore, the energization time of the supercooling prevention heater is also short, so that the vegetable room cannot be sufficiently warmed, and the conventional control method cannot prevent the vegetable room from being too cold.

た。[0005] Further, when the cooling capacity is adjusted to a minimum (hereinafter referred to as a weak setting), the temperature of the freezing compartment and the condenser is relatively high, so that the vegetable compartment does not easily become too cold. Therefore, it is desirable to shorten the energization time in view of the operation efficiency of the subcooling prevention heater. However, as shown in FIG. The compressor ON time is short,
The OFF time becomes longer. Therefore, the subcooling prevention heater is ON.
The time was long and the vegetable room was too warm.

A freezer compartment temperature sensor for detecting the temperature of the freezer compartment, and a supercooling prevention heater for preventing the refrigerating compartment from being excessively cooled by the cold from the freezer compartment or the evaporator. This controls the energization of the subcooling prevention heater.

をすることができる。According to the above configuration, the compressor is turned on.
Then, when the temperature of the freezing room sensor falls and becomes equal to or lower than the threshold value (the vegetable room tends to be too cold), the supercooling prevention heater is turned on to prevent the vegetable room from being too cold. When the freezer temperature reaches the off-temperature, the compressor is turned off, the freezer temperature rises, and when the freezer temperature exceeds a threshold (the vegetable room does not become too cold), the supercooling prevention heater is turned off. Efficient operation can be performed without warming the room.

ことができる。[0009] When the setting is strongly set by a dial or the like (when the threshold value is higher than the ON temperature), the vegetable compartment tends to be too cold, but once the supercooling prevention heater is once turned ON, the temperature of the freezing compartment sensor rises above the threshold value. Instead, since the ON state is maintained as it is, it is possible to reliably prevent the vegetable compartment from becoming too cold.

することができる。When the setting is weakly set by a dial or the like (when the threshold value is lower than the OFF temperature), the vegetable compartment does not become too cold, but the temperature of the freezing compartment sensor does not drop below the threshold value. However, since the heater is kept in the OFF state, the vegetable room can be prevented from being overheated due to excessive energization of the supercooling prevention heater. Furthermore, even if the set temperature inside the refrigerator is adjusted with a dial or the like, the stored food can be reliably prevented from freezing and low-temperature damage, so the heat insulating material that separates the refrigerator compartment from the freezer compartment is thinned, and the contents of the storage compartment are reduced. The product can be widened.

害から防止することができる。When the outside air temperature is low, even if the freezing room or the evaporator is not too cold, the temperature difference between the outside air and the inside of the refrigerator is small, and the cooling heat leakage to the outside of the refrigerator is reduced. If the vegetable room tends to be too cold,
According to the above configuration, the judgment control based on the outside air temperature is added, so that if the outside air temperature is low, the supercooling prevention heater is kept ON, and if the outside air temperature is high, the same control as in claim 1 is performed. Therefore, the food can be more reliably prevented from freezing and causing a low-temperature damage.

温度と閾値との関係を変えてもよい。The threshold value of the freezer compartment 4 and the high and low temperature values of the outside air temperature are not limited to the above because the optimum values vary depending on the internal volume of the storage compartment and the cooling performance. Further, the relationship between the set temperature of strong, medium, and weak by the dial 17 and the threshold value is not limited because the optimum relationship changes due to the influence of the heat insulating material and the like. For example, in the medium setting, the threshold value is set between the ON temperature and the OFF temperature of the compressor 9, but when the cooling heat leak to the vegetable compartment 3 is small due to the influence of the heat insulating material, the medium setting is the same as the weak setting. Alternatively, the threshold may be equal to or lower than the off-temperature, and the relationship between each set temperature and the threshold may be changed according to the degree of leakage of cold heat to the vegetable compartment 3.
