Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Figure 4 , Figure 5 shows a structural diagram of an embodiment of the present invention, Figure 4 It is a front view of the evaporator freezing prevention device of an indirect refrigerator, Figure 5 It is a side sectional view of the evaporator freezing prevention device of an indirect cooling refrigerator.

[0031] Such as Figure 4 As shown, the upper end of the evaporator 3 is fixed on the inner box body 2 through a fixing device 10 , and an expanded concave portion 11 serving as an air flow path is formed between the inner box body 2 and the evaporator 3 .

[0032] The above-mentioned expanded concave portion 11 can prevent the evaporator 3 and the inner box body 2 from forming a part in contact with each other. In the prior art, although the inner box 2 may not be in contact with the inner area of ​​the evaporator 3 , the inner box...

Abstract

The ice preventer for evaporator in indirectly cooling electric refrigerator has one expanded notch part formed inside the refrigerator body. The expanded notch part has the functions of forming air flow between the refrigerator body and the evaporator and separating the evaporator and near part from the inside refrigerator body. The present invention has the effects of preventing icing between the evaporator and the inside refrigerator body and caused ice breaking sound.

Description

technical field [0001] The present invention relates to an indirect-cooled refrigerator, and furthermore, relates to an evaporator freezing prevention device of an indirect-cooled refrigerator that can bring the following effects: by reducing the contact surface between the evaporator and the inner box, it can Reduces breakage of ice generated on contact surfaces. Background technique [0002] Generally, a refrigerator is a device for freezing food or keeping food fresh in a refrigerated state, and can store food for a long time. [0003] According to different cooling methods, refrigerators are divided into direct cooling refrigerators and indirect cooling refrigerators. In the direct cooling refrigerator, since the evaporator used in the freezing cycle is directly exposed to the cooling space of the freezer and the refrigerator, heat exchange can be directly performed between the stored food and the evaporator. However, the above-mentioned direct-cooling refrigerator has...
