Direct-cooling refrigerator

Abstract

The invention provides a direct-cooling refrigerator which comprises a refrigerating liner, wherein the refrigerating liner comprises an open side corresponding to a door body, four side walls adjacent to the open side, and a rear wall opposite to the open side; a first evaporating pipe group for refrigerating the refrigerating liner is arranged on at least one wall surface of the side wall and the rear wall, and is connected with a compressor; and a frost inducing part is arranged between the compressor and the first evaporating pipe group, and comprises a second evaporating pipe; and a refrigerant is enabled to flow through the second evaporating pipe group from an outlet of the compressor firstly, and then to flow into the first evaporating pipe group, so that the direct-cooling refrigerator not only can achieve the purpose that frost formation amount in a refrigerating chamber decreases remarkably, but also can enable the frost formation part to be effectively controlled.

Description

technical field [0001] The invention relates to a direct cooling refrigerator, in particular to a direct cooling refrigerator capable of reducing the amount of frosting inside a freezing chamber. Background technique [0002] A refrigerator is a device that uses the cooling effect of the refrigerant in the refrigeration circuit during compression, condensation, expansion, and evaporation to maintain the interior of the refrigerator at a low temperature, thereby preserving food. [0003] Divided by type, refrigerators can be divided into cold air circulation refrigerators and direct cooling refrigerators. A cold air circulation refrigerator uses a fan to circulate cold air inside the refrigerator for freezing or refrigeration. A direct cooling refrigerator does not use a fan, but directly freezes or refrigerates. [0004] The casing of the direct cooling refrigerator is provided with a multi-layer plate evaporator. When the food is placed on the evaporator, the cold air fr...

Problems solved by technology

Like this, when using the existing direct-cooling refrigerator, the surface of the refrigerating evaporator will be in direct contact with the hot and humid air inside the freezer compartment. Since the density of the hot air is lower than that of the cold air, it will accumulate in the front upper part of the box. A large amount of hot and humid air causes obvious local frosting

With the increase of the service cycle, the temperature in the freezer room will easily rise due to the thick frost layer, which will cause the cooling performance of the direct cooling refrigerator to decline, seriously affecting the normal use of users
