Embodiment Construction

[0029] like Figure 1 to Figure 6 As shown, the box body 1 of the direct cooling refrigerator provided by the present invention has a freezer compartment 2 inside. The direct-cooling refrigerator can only have the freezing chamber 2 or have the freezing chamber 2 and the cold storage chamber, and a pickle preservation chamber can also be set inside it. The freezer compartment 2 is provided with an evaporator 10 capable of dividing its interior into certain spaces. That is, a plurality of evaporators 10 are provided inside the freezer compartment 2 . The evaporator 10 is composed of a heat exchange panel 11 and refrigerant pipes 12 . The heat exchange panel 11 divides the freezer compartment 2 into certain spaces. The inside of the freezer compartment 2 can be provided with multi-layer heat exchange panels 11 . But when the internal space of the freezing compartment 2 is small, only the bottom surface of the freezing compartment 2 is provided with the heat exchange panel 11...

Abstract

This invention relates to a direct freezing refrigerator, which comprises box body with cold room, the heat exchange panel whose bottom has a certain batter to discharge condensation water, dividing the cold room to a certain space, and coolant pipe setting in the heat exchange panel in back and forth bending form. By setting heat exchange panel or flow guiding unit, it can discharge condensation water quickly. Said structure can decrease the condensing time, besides, it can prolong the defrost cycle and decrease the electric consumption of refrigerator.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a direct cooling refrigerator capable of reducing the amount of frost on the surface of an evaporator and reducing the frequency of defrosting operations. 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. 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. The casing of the direct cooling refrigerator is provided with a multi-layer plate evaporator. When the food is placed on the evapo...
