A foamed heat insulating material (12), such as polyurethane, is injected into the space between 1), the inner box (9) and the outer box (10) through the injection hole (13) and solidified by foaming. The machine room (5) accommodates a condensing unit composed of a refrigerating electric compressor (14), a condenser (15), a blower (16), etc., inside the machine room (5). A grill (19) having a suction port (17) and a blowout port (18) is disposed, a side plate (20) is disposed on a side surface, and an opening (21) is provided on a back surface of the machine room (5). I am trying. Further, in the top table (6), the front curved portion (6A) is engaged with the lower wall (22A) of the front upper frame (22) to which the door (2) is rotatably attached, and the rear portion is provided with a heat insulation box (6A). 4) and the back surface of the machine room (5), that is, the back surface (10A) and one end of the outer box (10) are heat insulating boxes (4)
And the side plate (20) is fixed to the other end, and then screwed to the upper frame (23).

る。By the way, the foamable heat insulating material (12) such as polyurethane may deform the outer box (10) immediately after foaming or during use as a refrigerator due to a so-called void (air pool). That is, in the vicinity of the corners of the inner box (9) and the outer box (10), turbulent flow occurs due to the change in the flow of the foaming heat insulating material (12), which is one of the causes, as shown in FIG. Void (27) occurs. However, according to the present invention, the top table (6) is provided at the place where the void (27) is likely to occur.
Since the mounting wall (6D) of is opposite, this mounting wall (6D)
The outer box (10) can be reinforced by the void (27)
It is possible to prevent the outer box (10) from being deformed due to the occurrence of.
