The refrigerating chamber 14 is a storage chamber for refrigerating storage, and is specifically set to about 2 to 3° C. and cooled. Further, the partial chamber 20 provided in the refrigerating chamber 14 is set to about -3°C suitable for microfreezing storage, and the temperature of the partial chamber 20 can be set to a chilled temperature range of about 1°C.

The vegetable compartment 17 is a storage compartment whose temperature is set slightly higher than that of the refrigerator compartment 14. Specifically, it is set to 4 to 7° C. and cooled. Since the vegetable compartment 17 becomes highly humid due to the moisture emitted from stored foods such as vegetables, dew condensation may occur if it is locally too cold. Therefore, the amount of cooling is reduced by setting the temperature to a relatively high temperature, thereby suppressing the occurrence of dew condensation due to local overcooling.

The freezer compartment 18 is a storage compartment set in a freezing temperature range, and is normally set to about -18°C for cooling. It may be cooled.

The switching compartment 15 is a storage compartment in which the temperature inside the refrigerator can be changed, and can be switched from a refrigerating temperature range to a freezing temperature range depending on the application.

A cooling chamber 21 is provided on the back of the vegetable compartment 17. In this cooling chamber 21, a cooler 22 for generating cold air and a cooling fan 23 for supplying cold air to each compartment are installed. Further, below the cooler 22, a defrosting means 24 (hereinafter referred to as a heater) composed of a glass tube heater or the like is provided.

The cooler 22 includes a compressor 25, a heat exchanger (not shown), a condensation prevention pipe (not shown) for preventing condensation from forming at the opening of each chamber, and a capillary tube (not shown). A refrigerating cycle is configured by being connected in a ring, and cooling is performed by circulation of the refrigerant compressed by the compressor 25 .

Each of the doors 9 to 13 includes a metal panel door 30 forming an outer front plate, an upper cap door 31 covering the upper end of the panel door 30, and a lower cap door 32 covering the lower end. Urethane 40 is filled and the inside is closed with an inner door 33. - 特許庁
