However, in the above-described conventional configuration, the strength around the machine room 15 is ensured despite the fact that the outer box 2 and the inner box 6 are integrally formed by the heat insulator 11. Therefore, it is necessary to increase the thickness of the outer box 2, the angle 4, the reinforcing plate 5, and the like, so that the weight cannot be reduced. In addition, there are disadvantages in that the number of parts is large and the number of assembly steps is large.

Further, in the above-mentioned conventional configuration, too many seal members are provided to block the inside and outside of the refrigerator, the seal members adhere to the machine room cover 21 due to deformation of the pipe 20, or the pipe 20 hits. There was a disadvantage.

The present invention solves the conventional problems,
By integrating the storage room where the outer and inner boxes are made of heat insulators and the machine room box where the bottom and both sides of the machine room are made of heat insulators, it is possible to reduce the weight of products and assemble them. An object of the present invention is to provide a showcase box that can be easily manufactured.

Another object of the present invention is to provide a guide groove of a concave portion at both ends provided between lower edge receiving plates extending in a width direction below a lower edge constituting a storage chamber and divided into right and left parts in a U-shaped cross section. An object of the present invention is to insert a partition plate into a partition body having a pipe, so that pipes can be easily accommodated without using screws or the like.

[0010]

In order to achieve this object, the present invention provides a storage room in which an inner box and an outer box are formed of a heat insulator, and an outer box support in which both side surfaces and a top surface of a machine room are integrally formed. Plate, a bottom plate having an opening on both sides and a lower surface and a flange surface on the front and back,
A machine body box composed of the bottom plate and a flat plate closing the bottom surface of the outer box, and a heat insulator forming the storage chamber, wherein a space surrounded by the outer box and the machine room box is integrally formed. It was.

As a result, the thickness of the outer box can be reduced, the angle and the reinforcing plate can be eliminated, and the product can be reduced in weight and the number of assembling steps can be reduced.

A partition body extending in the width direction below the lower edge constituting the storage chamber and provided with a guide groove having concave portions at both ends provided between lower edge receiving plates divided into right and left with a U-shaped cross section. Then, a partition plate was inserted.

Thus, the pipe can be securely stored without using screws or the like.
