Abstract

PROBLEM TO BE SOLVED: To provide a refrigerator easy to assemble. SOLUTION: Since a plurality of protrusions pointing outwardly are formed on the flange of an inner box, and holes fitted in the respective protrusion parts are formed in the flange of an outer box, a radiation pipe is mounted on the flange of the inner box. When the radiation pipe is inserted in the recessed part of the outer box, it is fitted in the hole of the flange of the inner box, positioning is practicable and the refrigerator can be easily assembled.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator in which an inner box and an outer box constitute an insulated box.

[0002]

2. Description of the Related Art A refrigerator in which an inner box and an outer box constitute an insulating box body is disclosed in, for example, Japanese Patent Application Laid-Open No. H11-101538.

A refrigerator similar to the above refrigerator will be described with reference to the drawings. 1 shown in FIG. 1 is a metal outer box, 2 is a synthetic resin inner box, and this inner box is a freezer
(A storage room controlled by the above). An inner box constituting a refrigerator compartment (for example, a storage compartment controlled at 3 ° C.) is also provided, but not shown. Reference numeral 3 denotes a heat radiation pipe, which is formed by bending a part of a condenser constituting a refrigerant circuit as shown in FIG.
It is arranged around the opening of the inner box.

[0005] In FIG. 5 and FIG. 6, reference numeral 51 denotes a flange of the inner box 2, 52 denotes a support portion formed at the end of the flange, and 53 denotes an aluminum tape for attaching the heat radiation pipe 3 to the support portion 52. . Numeral 54 is a flange formed in a concave shape, and has a concave portion 55 into which the flange 51 in which the heat radiating pipe 3 is attached to the support portion 52 is inserted.

[0005]

In the refrigerator shown in FIGS. 5 and 6, the radiating pipe 3 is attached to the supporting portion 52 with the aluminum tape 53, and then the flange 51 is inserted into the concave portion 55. Flange 51 is replaced with concave flange 54
Since it is not fixed to a predetermined place, it is easy to shift. 5 and 6, in particular,
There was a risk of shifting to the front or back of the drawing. Because of this tendency, it was not easy to assemble.

The present invention provides a refrigerator in which an inner box and an outer box can be mounted at predetermined positions.

[0007]

The present invention comprises an inner box made of synthetic resin and an outer box made of metal, wherein the inner box has an outwardly-facing flange, and the outer box has a cross section. Forming a substantially concave inward flange, attaching a heat radiating pipe to the flange of the inner box, and inserting the same into the concave flange of the outer box to form a heat insulating box body, wherein the flange of the inner box has A plurality of outwardly extending convex portions are formed, and a concave portion or a hole that fits into the convex portion is formed on the flange of the outer box.

Further, a part of a condenser constituting a refrigerant circuit is used as the heat radiation pipe.

Further, a freezer compartment is formed by the inner box.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 4 show a refrigerator according to an embodiment of the present invention. Although FIG. 1 has been used in the description of the prior art, the basic structure is the same, so it is also used as a drawing of the refrigerator of the present embodiment, and only the parts not described are described.

The refrigerator has a refrigerant circuit in which a refrigerant compressor, a condenser, a decompression device, and an evaporator are connected in a ring form by a refrigerant pipe, but is not shown in FIG.

Further, since the inner box 2 is formed by vacuum forming, its shape is limited by its thickness, and it is not easy to further complicate the shape of the inner box. In addition, those having about the convex portions described later can be molded.

The flange 51 of the inner box 2 is formed outward on the outer periphery, and the flange 54 of the outer box 1 is formed inward with a substantially concave cross section.

2 to 4 show a flange 5 of the inner box 2.
For example, a plurality of convex portions 4 are formed so as to extend outwardly. For example, the convex portions 4 are formed at two locations on each of the flanges 51 on three sides, that is, at a total of six locations. Reference numeral 5 denotes a square hole (hole) that fits into the projection 4 and is formed on the flange 54 of the outer box 1.

In the refrigerator configured as described above, first, the heat radiating pipe 3 is placed on the convex portion 4 of the flange 51 of the inner box 2,
It is attached to the convex portion 4 with an aluminum tape 53. Then, the convex portion 4 and the flange 51 are inserted into the concave portion 55 (see FIG. 3).

When the projection 4 and the flange 51 are inserted into the recess 55, the projection 4 fits into the square hole 5, and the inner box 2 is hardly displaced from the outer box 1 (see FIG. 4).

As described above, the refrigerator is easy to assemble since the inner box is positioned and hardly displaced when the inner box is attached to the outer box.

Although this embodiment has been described with respect to the example in which the square holes are provided, any shape may be used as long as it has a shape that fits into the protrusion of the flange of the inner box. For this reason, a round hole or a concave portion may be formed in the flange of the outer box.

Although an example using a part of the condenser as the heat radiating pipe has been described, an electric heater may be used.

[0020]

As described above, according to the present invention, a plurality of outwardly extending projections are formed on the inner box flange, and the outer box flange is provided with a recess or a hole which fits into the projection. Since the heat radiation pipe is attached to the flange of the inner box and inserted into the concave portion of the outer box, the hole is fitted with the hole of the flange of the inner box. be able to.
