Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a refrigerator, and particularly to a multi-temperature refrigerator that can store various foods at appropriate temperatures.

[Conventional technology]

FIG. 10 shows a conventional example shown in, for example, Japanese Utility Model Application Publication No. 55-54874, in which dedicated doors are provided for the freezer compartment 2, refrigerator compartment 8, and vegetable compartment 16, and the upper part of the refrigerator compartment 8 is A low-temperature case 40 is arranged, with reference numeral 4 a cooler constituting a cooling system, 6 a fan for forced circulation of cold air, and 18 a damper thermostat for controlling the temperature inside the refrigerator compartment 8. In the refrigerator configured in this way, the cold air cooled by the cooler 4 is circulated and cooled in the freezer compartment 2 by the fan 6, and the cold air controlled by the damper thermometer 18 is circulated to the refrigerator compartment 8, vegetable compartment 16, and low-temperature case 40. It is circulated and cooled to a predetermined temperature.

Therefore, since the temperatures of the refrigerator compartment 8, vegetable compartment 16, and low-temperature case 40 are determined by the air volume set in advance by ducts, etc., each compartment is not controlled independently, but is controlled by the temperature of the refrigerator compartment 8. It will be controlled by the damper thermostat 18. Therefore, the low-temperature case 40, which requires precise temperature control to store food, is also affected by the temperature of the refrigerator compartment 8.If the refrigerator compartment is strongly cooled, the low-temperature case 40 will become too cold; The temperature will be too high and it will be difficult to control the temperature within the specified range.
Furthermore, the temperature of the low-temperature case 40 tends to fluctuate depending on the opening and closing of the refrigerator door, the outside air temperature, and the operating rate of the compressor, making it difficult to precisely control the temperature.

[Problem that the invention seeks to solve]

Especially with conventional equipment, if a cold room is placed next to a room with a low temperature such as a freezer, the temperature of the cold room, which is trying to maintain it at about 0℃, will drop due to heat leakage from the freezer when the outside air temperature is low. The ice-making function is usually located in the freezer compartment, but there is a problem in that opening and closing the door every time ice is made deteriorates the compartment in which frozen foods are stored.

[Problem that the invention seeks to solve]

The purpose of this invention is to eliminate the above-mentioned drawbacks.In particular, in order to improve the storage stability of food in a low-temperature room, the present invention has a dedicated chamber independent of the refrigerator compartment, and also has an independent ice-making compartment. The purpose of this invention is to obtain a 5-temperature refrigerator with a high temperature.
