That is, the system controller 60A determines whether the cook-chill mode selection key is input through the key input means 10 (S11), and sets the cook-chill mode when the cook-chill mode selection key is input (S12). .

Next, in the state in which the cooking mode is set, the amount of food in the cooking chamber is measured through the cooking chamber load detecting means 70, and the load value thereof is compared with a reference value (medium level; 250 g) (S13). At this time, if the load of food is more than 250g (branch of S13) on the basis of the medium level (= 250g), the load level is divided into lower levels if it is less than 250g (branch of S13) (S14-S16). Then, each level value is divided into 120 minutes, 90 minutes, and 60 minutes, respectively, to perform the cooking mode operation time determination step of dynamically setting the cooking mode operation time (S17-S19).

After performing the cook-chill mode operation time determining step, it is determined whether the cook-chill mode is used again to reduce the system error (S20). In this case, if the cook-chill mode is set (Y branch of S20), it is checked whether the cook-chill mode operation time specified above has elapsed (S22), and until the cook-chill mode operation time has elapsed (N-branch of S22), the cold air adjusting means ( 40) is opened to the maximum, and the cooking mode display means 50 is driven, and at the same time, the cooking mode operation step of operating the refrigerator compartment in the rapid refrigeration mode (S21) is performed.

When the specified operation time has elapsed during the execution of the cooking mode operation step (Y branch of S22), the system controller 60A immediately releases the cooking mode (S23), opens the cold air control means 40 in the normal mode, and cooks. By turning off the mode display means 50 and performing the cooking mode release step of operating the refrigerating compartment in the normal refrigeration mode (S24), it is possible to flexibly control the operation time of the cooking mode according to the food lower floor in the cooking chamber.
