Description

[Detailed explanation of the idea] The present invention relates to an outer box for an electric refrigerator.

The outer case of an electric refrigerator is generally assembled by joining a pair of side plates, a top plate, and a back plate to each other by welding or the like.

In this case, the front corner of the outer box is connected to the upper front flange 2 of the top plate 1 by the side plate 3, as shown in FIG.
It is formed by overlapping the side front flanges 4, welding the upper edge of the flange 4 to the front edge of the top plate 1, and finishing the welded portion with a file or the like.

The welded parts at the front corners were surprisingly easy to notice and did not look very attractive.

Furthermore, since manual finishing is required, the quality tends to vary and the workability is poor.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an outer box for an electric refrigerator whose front corner portion can be formed in an attractive and efficient manner.

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

FIG. 2 shows the right front corner of the outer box according to the present invention, and this corner is attached to the right side plate 11, the top plate 12, and these corners, and Decorative cover 1 with a shape that complements the external shape of
It is formed from 3.

Referring to FIG. 3, the side plate 11 has a side front flange 14 bent at a substantially right angle toward the inside of the outer box and a side upper surface flange 15. In this case, the side upper surface flange 15
The front portion of the connecting flange 16 is bent downward with a predetermined step and extends horizontally from the bent portion.

This connecting flange 16 has a front edge that forms a predetermined gap with the side front flange 14, and a U-shaped recess 17 is provided on this front edge.

The side front flange 14 includes a first portion 14a bent at a substantially right angle to the side plate, a second portion 14b bent inward with respect to the first portion, and a horizontal cross section further from this portion. The third part is bent to form a roughly U-shape.
14c, the upper edges of which are formed to be located within a virtual plane that includes the connecting flange 16.

Note that a condenser tube (not shown) is arranged inside the U-shaped portion formed by the second portion 14b and the third portion 14c.

On the other hand, the top plate 12 includes a front upper flange 18 and side flanges 19.

The front upper flange 18 is formed to be flush with the lateral front flange 14, but is formed laterally to engage along the second portion 14b of the flange 14. A tongue piece 20 is provided.

The side flange 19 has a substantially similar shape to the side upper surface flange 15 and is formed to fit under the flange 15 .

Therefore, similar to flange 15, this flange 19
The front portion thereof is also a connecting flange 21 formed in a stepped shape so as to cooperate with the aforementioned connecting flange 16.

Then, the side plate 11 and the top plate 12 are connected as follows.

That is, the side flange 19 of the top plate 12 is engaged along the lower side of the side upper surface flange 15 of the side plate 11, and the tongue piece 20 is engaged with the second portion 14b of the side front flange 14.
By engaging with the connecting flanges 16 and 21 to position them, and then riveting the connecting flanges 16 and 21 through the holes 22 and 22 formed therein, the side plate 11 and the top plate 12 are mutually connected. firmly fixed.

The corner portions connected by riveting in this manner are more strongly reinforced by an abbreviated reinforcing metal fitting 23 attached from the inside, as shown in FIG.

Next, the decorative cover 13 will be explained with reference to FIGS. 5 and 6.

This decorative cover 13 is disposed in a recess in a corner portion defined by the connecting flange 16 formed in a stepped shape as described above, and has a shape that complements the outer shape of this corner portion. It has one main body 24.

This cover main body 24 has a retaining groove 25 at its lower front edge that engages with the upper edge of the first portion 14a of the side front flange 14, and a gap in front of the connecting flange 16. In this case, the hanging piece 26 has a reinforcing metal fitting 23.
An engagement stepped portion 27 is provided for engagement with and for preventing slippage.

In addition, this engagement step part 27 can also be formed so that it may engage with the U-shaped recessed part 17 formed in the front edge of the connection flange 16.

Therefore, when this decorative cover 13 is attached to the recessed part at the corner part, by forcibly applying a pressing force thereto, the engagement step part 27 gets over the reinforcing metal fitting 23 and is locked to the lower end part thereof. Since the upper edge of the first portion 14a is engaged in the engagement groove 25, it can be reliably attached with a simple one-touch operation.

Incidentally, each of the side plate 11, the top plate 12, and the decorative cover 13 is finally fixed with a heat insulating material 28 that is foam-molded on-site between the inner box (not shown) that will be attached later.

As is clear from the above description of the embodiments, according to the present invention, since the connecting portion between the top plate and the side plate at the front corner portion is covered with a decorative cover, this corner portion can be finished in an attractive manner.

Furthermore, the decorative cover can be easily attached with a one-touch operation, and there is no need for finishing after welding as in the conventional case, so work efficiency can be improved and productivity can be improved.
