Embodiment Construction

[0017] Such as figure 2 As shown, a freezer compartment 2 is provided in the refrigerator body 1 of the present invention which can be continuously refrigerated, and a cold air conduit 10 is arranged at the rear of the freezer compartment 2 and together with the freezer compartment 2 constitutes a cold air circulation channel, the partition plate 7 of the cold air conduit 10 A cold air inlet 12 and a cold air discharge port 11 are arranged on the top. Casing 1 is divided into freezing chamber 2 and refrigerating chamber by a barrier layer (not shown) made of heat-insulating material. The barrier layer has many communication holes so that the cold air in the freezing chamber and the refrigerating chamber can communicate freely. The cold air can flow into the refrigerating chamber, and the cold air in the refrigerating chamber can flow into the cold air duct 10 through the freezing chamber.

[0018] Two evaporators 24a, 24b are provided inside the cold air conduit 10 for heat ...

Abstract

A refrigerator able to continuously refrigerate is composed of casing, cold air channel, two evaporators with own cold channels, the barrier for selectively cutting off one of their cold channels, fan for forcing circulation of cold air, and the defrosting heaters (one for each evaporator). When the cold air channel of an evaporator is cut off and the evaporator is defrosted, the other evaporator still works for refrigerating, so resulting in high refrigerating efficiency.

Description

1. Technical field: [0001] The invention relates to a refrigerator, in particular to a refrigerator in which a freezing device can continue to operate and keep cooling when evaporation and frosting are eliminated. 2. Background technology: [0002] As a refrigeration machine, a refrigerator keeps the temperature inside the refrigerator through repeated cycles of compression, condensation, expansion, and evaporation of the refrigerant, and keeps the food in the box fresh for a certain period of time. The refrigeration cycle system of a refrigerator is mainly composed of a compressor, a condenser, an expansion valve and an evaporator; the compressor compresses the low-temperature and low-pressure refrigerant gas into a high-temperature, high-pressure refrigerant gas and pounds it into the condenser, which is condensed due to the action of external air The liquid refrigerant is decompressed by the expansion valve and evaporates in the evaporator under low pressure, thereby real...
