Problems solved by technology

However, the heat insulation box 2 having the above-mentioned structure has the recessed portion 2a in the lower back portion, so the rigidity is lowered.
When the rigidity of the heat insulating box 2 decreases, the durability of the heat insulating box 2 decreases due to deformation of the heat insulating box 2
In addition, due to this deformation, a gap is generated in the heat insulating box 2
Due to this gap, the heat insulation performance of the heat insulation box 2 is reduced.

Abstract

A refrigerator is provided with a refrigerator body (20) which has a heat-insulated box (21) in which storage chambers including a cold-storage chamber (29) are formed. The heat-insulated box (21) is provided with an outer box (23), an inner box (22), and a heat-insulating material (24) disposed between the outer box (23) and the inner box (22). The refrigerator is also provided with a containing section (101) which contains, among refrigeration cycle-related devices including devices constituting the refrigeration cycle, external devices exposed to the outside air. The containing section (101) is disposed at the rear of the lower portion of the lowermost storage chamber of the heat-insulated box (21). The refrigerator is also provided with a heat-insulated wall which is formed by integrating together the bottom surface of the lowermost storage chamber and the bottom surface of the containing section. The configuration increases the rigidity of the lower part of the outer box (23), and as a result, the rigidity of the entire heat-insulated box (21) is high.

Description

technical field [0001] The invention relates to a refrigerator with a heat-insulating box body. Background technique [0002] The heat insulation box used for a refrigerator has a recessed part in the back lower part as shown in patent document 1. Figure 18 It is a sectional view of the refrigerator described in patent document 1. The heat insulation box 2 of the refrigerator 1 has the outer box 3 made of steel plates, and the inner box 4 made of resin. Between the outer case 3 and the inner case 4, a heat insulating material 5 is filled by foaming. The heat insulation box 2 has a recessed part 2a in the back lower part. The recessed part 2a is formed in the shape which cut off part of the back side lower part of the heat insulation box 2 over the whole left-right direction. A machine chamber 8 is provided in the recess 2a. The machine room 8 is provided with a compressor 6 and a compressor support stand 7 for supporting the compressor 6 . Compressor 6 forms part of a ...
