Description

Temperature Control Method of Refrigerator with Ambient Temperature Sensing Function

The present invention relates to a temperature control method of a refrigerator having an outside air temperature sensing function, and more particularly, when a refrigerator is installed in a place where a warehouse or an air conditioning facility is not provided, the refrigerator is automatically cooled according to an external temperature change in a cold or a cold season. It relates to a temperature control method of a refrigerator equipped with an outside air temperature sensing function to properly adjust the operation rate of the.

In general, the control device for controlling the internal temperature of the refrigerator in the refrigerator determines whether to operate the cooling fan and the compressor according to the temperature sensor for detecting the temperature in the refrigerator and the internal temperature detected by the temperature sensor. The control unit is configured to generate a cooling fan and a compressor control signal, and a cooling fan driving unit and a compressor driving unit to drive or turn off the cooling fan and the compressor by the control signal output from the control unit.

Thus, when power is supplied to the refrigerator, the high temperature sensor detects the high temperature and applies it to the control unit. The control unit searches the high temperature to determine whether the compressor and the cooling fan are driven or off.

As a result of the determination, the compressor and cooling fan driving signals are output when the compressor and the cooling fan are driven, and the compressor driving means and the cooling fan driving means which receive the compressor and cooling fan driving signals apply power to the compressor and the cooling fan, respectively. Will be driven.

If the high temperature detected by the high temperature sensor is a driving off temperature of the compressor and the cooling fan, the controller outputs an off signal to the compressor and the cooling fan driving means according to the signal. Shut off the power supply to turn off the compressor and the cooling fan.

The conventional refrigerator is set by the temperature control device installed inside the refrigerator to save power operation, weak cooling, medium cooling, strong cooling, etc., so that the user adjusts the strength of the freezing and refrigeration of the refrigerator according to the increase or decrease of load in the refrigerator or the season. For example, in the summer, the temperature of the freezer and the refrigerating chamber is operated by 'cold cooling', and in winter, the operation of 'freezing' or 'weak cooling' is performed by the user's subjective judgment depending on the temperature change of the outdoor air and the degree of load. By adjusting the inside temperature, the proper inside temperature setting was not well established. Especially when the refrigerator is installed in a place where the warehouse or the heating and cooling facilities are not equipped, the user can set the inside temperature of the refrigerator according to the change of the temperature of the outside air or the degree of load There has been a hassle to adjust.

In order to solve the above problems, the temperature control method of the refrigerator equipped with the outside temperature sensing function of the present invention is to install the outside temperature sensor to detect the outside temperature in the controller of the refrigerator to automatically change the refrigerator according to the change of outside temperature. The technical task of the present invention is to provide a temperature control method capable of maintaining a proper internal temperature of a refrigerator by adjusting the operation rate of the refrigerator.

Referring to the configuration of the circuit for controlling the temperature of the refrigerator according to the present invention with reference to FIG. 1, first, an outdoor temperature sensor 10 capable of detecting a temperature change of the outside air, and a freezer compartment temperature detecting a temperature change of the freezer compartment. Sensor 11, a refrigerating chamber temperature detecting sensor 12 for detecting a change in temperature of the refrigerating compartment, and a sensor signal detecting means for detecting signals of the respective temperature detecting sensors 10, 11, and 12 (13), a cooling fan 18 installed at the rear side of the freezing chamber and discharging cold air in the freezing and refrigerating chambers, a compressor 16 for circulating the refrigerant, and driving the compressor 16 and the cooling fan 18. Outputting a control signal for driving the driving means (15) and (17) and the driving means (15) and (17) according to the temperature change of the temperature sensor (10) (11) (12). It is the structure containing the control part 14. As shown in FIG.

With reference to the block circuit diagram of the configuration described above with reference to the drawing of Figure 2 Looking at the temperature control method of the refrigerator with an outside temperature detection function according to the present invention in detail, first by the outside temperature sensor 10 installed inside the control unit of the refrigerator When the outside air temperature is detected at 5 ° C. to 20 ° C., the control unit 14 recognizes the outside air temperature detected by the outside air temperature sensor 10 through the sensor signal detecting means 13 to determine an operation mode of the refrigerator. The operation mode of the compressor is converted into 'cold cooling' and the compressor 16 and the cooling fan 18 are driven until the preset 'cold cooling' set temperature is reached in the controller 14, and when the set temperature is reached, the compressor 16 ) And the cooling fan 18 are stopped.

When it is detected that the outside temperature is 20 ° C. or more by the outside temperature sensor 10, the control unit 14 recognizes the outside temperature detected by the outside temperature sensor 10 through the sensor signal detecting means 13. After determining the operation mode, the operation mode of the refrigerator is converted into 'cold cooling', and the compressor 16 and the cooling fins 18 are driven until the preset temperature of 'cold cooling' preset by the controller 14 is reached. When the set temperature is reached, the driving of the compressor 16 and the cooling fan 18 is stopped.
