Blocking the means and the refrigerating chamber is preferably made of a cook-chill mode release step of operating in the normal refrigeration mode and ends (S17).

Operation by the method and apparatus for controlling the cooking system of the refrigerator according to the present invention configured as described above are as follows.

The overall operation of the cooking chamber control system according to the present invention, when the load (food) flows into the cooking chamber, so that the temperature of the cooking chamber increases rapidly, the system controller 60A detects this and automatically enters the cooking chamber mode, the cooking chamber mode. After the infiltration, when the measured value of the cooking chamber temperature sensing means 70 reaches a desired temperature (for example, about 2 ° C.), the cooking mode is automatically released. At this time, when entering the cooking mode, the cooking mode display means 50 is turned on, when the cooking mode is released, the cooking mode display means 50 is turned off, and when entering the cooking mode, the electronic damper 42, which is a cold air control means, is maximized. Open and supply a lot of cold air to the cooking chamber and keep the fridge in refrigerated mode. On the other hand, if the cookroom temperature does not reach the cookroom mode release temperature within the cookroom mode operation time limit, it returns to the normal mode.

That is, the system controller 60A detects the cooking chamber temperature through the cooking chamber temperature sensing means 10 and compares it with the first reference temperature (A ° C.) set for entering the cooking chamber mode (S11) to enter the cooking chamber mode. A first determination step is performed to determine if the temperature is high enough. As a result of the determination of the first determination step, if the cook chamber temperature is lower than the cook chamber mode inrush temperature, it is ignored, and if the cook chamber mode inrush temperature is higher (Y branch of S11), the cook chamber mode is automatically set (S12), and the cold air adjusting means 40 Drive the cooking mode display means 50 while opening the electronic damper 42 to the maximum to display the current cooking mode operation state to the outside, and the refrigerating chamber performs the cooking step setting step of operating in the rapid refrigeration mode (S13). do.

In the state in which the cooking mode is set, the system controller 60A continuously detects the cooking chamber temperature measurement value input from the cooking chamber temperature sensing means 70 and compares the cooking chamber temperature with an arbitrary second reference temperature (B ° C.). Does not reach the cook-chill mode release temperature (N branch of S14), the system controller 60A again performs a second discrimination step of determining whether the cook-chill mode operation time limit has elapsed (S15).

If the cooking chamber temperature does not reach the cooking chamber mode release temperature and the cooking chamber mode operation time limit has not elapsed (N branch of S15), the process returns to the cooking chamber mode setting step (S12) and the cooking chamber mode operation is determined. If the cooking chamber temperature reaches the cook-chill mode release temperature (Y branch of S14) or if the cook-chill mode release temperature is not reached within the cook-chill mode operation time limit (Y-branch of S15), the cook will be cooked. By releasing the mode (S16) to open the cold air control means in the normal mode, blocking the cooking means mode display means (S17), and the refrigerating chamber performs a cook-chill mode release step of operating and exiting in the normal refrigeration mode.

Therefore, by measuring the temperature of the cook chamber changing according to the food inside the cook chamber by the temperature sensing means by the method and apparatus for controlling the refrigerator Cook-Chill system according to the present invention, the automatic operation of the cook-chill mode in and out according to the detected temperature is automatically performed. It can be controlled by the user, so the user does not need to operate arbitrarily, so that the cooking system can be used conveniently, and the temperature of the cooking chamber can be adjusted appropriately according to the amount of food. There is usefulness to solve the problem of waste of power.
