That is, by disposing the two switches on different side surfaces, the refrigerator room 3 or the warm room can be provided from either the side surface where the operator performs the layout work or the side surface where the handle 6 is used for the moving operation. 4 can be changed, and a wasteful movement such as moving to either side can be eliminated in order to perform the switch operation. The state of these switches is displayed on the first refrigeration operation lamp 61, the second refrigeration operation lamp 85, the first refrigeration operation lamp 62, and the second refrigeration operation lamp 86. The switch operation can be performed in a desired state.

Then, the operation | movement operation | movement of the refrigerator compartment 3 and the warm compartment 4 which were comprised in this way is demonstrated.
First, the operation of the refrigerator compartment 3 will be described. By operating either the first refrigeration operation switch 56 or the second refrigeration operation switch 83, the refrigeration chamber 3 is activated, and the second CPU 89 of the programmable controller 88 is operated by the first refrigeration operation lamp 61 and the second refrigeration. The operation lamp 85 is turned on.
When the refrigerator compartment 3 is started up, the previously set temperature is stored in the second RAM 91 of the programmable controller 88, so that the set temperature is read from the second RAM 91 by the second CPU 89 and displayed on the refrigerator temperature display device 63. Is done. If the displayed temperature setting is acceptable, the refrigeration operation is started after a predetermined time.

That is, the second CPU 89 instructs the driving of the cooling unit 52 based on the temperature detection data of the refrigerator compartment thermistor 92 attached to the refrigerator compartment 3, thereby cooling the air in the refrigerator compartment 3. Furthermore, since the second CPU 89 controls the operation of the cool air blower fan 68 based on the temperature detection data of the thermistor described above, the cooled air can be circulated through the intermediate wall 43. The food stored in the chamber 47 and the second refrigerating chamber 49 can be refrigerated with the temperature set within the range of 5 to 15 ° C. being the center temperature.
At the same time, when the refrigeration operation is started after a predetermined time, the second CPU 89 causes the room temperature to be increased by the refrigerator compartment thermistor 92 attached to the first refrigerator compartment 47 and the second refrigerator compartment thermistor 93 attached to the second refrigerator compartment 49. And the result is displayed on the refrigeration temperature display device 63.

When changing the set temperature, the refrigeration temperature setting switch 57 is used. When the operator presses the temperature setting instruction button of the refrigeration temperature setting switch 57, the second CPU 89 reads the currently set temperature from the second RAM 91 and displays it on the refrigeration temperature display device 63. The operator sets the desired temperature by operating the temperature upper setting button or the temperature lower setting button of the refrigeration temperature setting switch 57 while watching the temperature display displayed on the refrigeration temperature display device 63. At this time, the second CPU 89 is programmed to change by 1 ° C. each time the setting button is pressed, and each time data is written to the second RAM 91 and displayed on the refrigeration temperature display device 63.

Moreover, when changing the preset temperature of the 1st storage chamber 48, the 1st storage temperature setting switch 59 is used. When the operator presses the temperature setting instruction button of the first warming temperature setting switch 59, the second CPU 89 reads the currently set temperature from the second RAM 91 and displays it on the first warming temperature display device 64. The operator operates the temperature upper setting button or the temperature lower setting button of the first storage temperature setting switch 59 while viewing the temperature display displayed on the first storage temperature display device 64 to obtain a desired temperature. Set. At this time, the second CPU 89 is programmed to change by 1 ° C. each time the setting button is pressed, and each time data is written to the second RAM 91 and displayed on the first storage temperature display device 64. Then, after a predetermined time has elapsed since the last data was written in the second RAM 91, the second CPU 89 determines that the last data is the set temperature and starts the warming operation. Since the subsequent process is the same as the process described above, the description thereof is omitted.
When the storage operation is started after a predetermined time, the second CPU 89 measures the room temperature by the first storage room thermistor 93 attached to the first storage room 48, and the result is displayed on the first storage temperature display device. 64.
