Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of attaching a compressor base on which an electric compressor incorporated in a refrigerator or the like is placed, and particularly improves the workability of the attaching operation.

Conventionally, for example, in refrigerators,
As shown in Japanese Patent No. 93, a board for mounting and fixing the electric compressor of the refrigeration cycle was attached from below the bottom flange of the machine room. In the structure shown in this publication, the work efficiency was poor because the board had to be held in close contact with the refrigerator while the rear end or front end of the board was being screwed on.

The present invention has been made to solve these drawbacks, and examples thereof will be described below.

(1) is the main body of the refrigerator, Figure 1 shows the back side, and (2)
) is an outer box made of steel plate, etc., and a machine room (4) is formed at the bottom of the back to house an electric compressor (3) included in the refrigeration cycle, and (5) is an outer box made of steel plate or the like. This is also a condenser included in the refrigeration cycle, and in the example, the main body (
1) It is provided on the back. Further, (6>) is a compressor base on which the compressor (3) is placed and fixed.

Now, in this proposal, in order to reinforce the outer box (2), the machine room (4) part of both side walls (2a) of the outer box (2) has an abbreviated reinforcing angle along its lower edge and rear edge. (7) is fixed by spot welding etc. This reinforcing angle (7) has a trailing edge flange (7a) and a lower edge flange (7b) on its rear edge and lower edge that protrude toward the machine room (4). The corner where the trailing edge flange (7a) and the lower edge flange (7b) intersect is slightly cut out to form a notch (8), so that the rear end surface of the lower edge flange (7b) is exposed. The rear edge flange (7a) slightly above the notch (8) has an elongated hole (9) and a screw hole (10) below the elongated hole (9). A locking protrusion (11) that protrudes upward and is completely bent is provided in the front part of the notch (8) of the lower edge flange (7b), and this locking protrusion (11) A sloped surface is formed so that the rear end gradually becomes higher toward the front.

Now, at the front of both ends of the compressor base (6), engaging parts (12) are formed which are bent upward into an abbreviated shape and facing both sides, and the engaging parts <12> are formed at the front ends of the compressor base (6). It has a pressure contact part (12a) which is bent diagonally upward. Further, at the rear of both ends of the compressor base (6), there are formed rising pieces (13) which are bent and raised up, and at the upper end thereof there is formed a tapered protrusion (13) which is bent forward.
4) is provided.

Therefore, to attach the compressor base 6) to the outer box (2), first insert the engaging claw (12) through the notch (8), then connect the engaging claw (12) and the compressor. The lower edge flange (7b) is inserted into the gap with the base (6), and the engaging claw (12) is engaged with the lower edge flange (7b). In this state, the compressor base (6
) is inserted forward, the protrusion (14) will then fit into the elongated hole (
9). Here, the long hole (9) and the protrusion 14
) are determined in advance so that they will be in the same position in the above-mentioned state. Therefore, when the rising piece (13) is about to come into contact with the trailing edge flange (7a), the front engaging claw (12)
) comes into contact with the locking protrusion (11) of the lower edge flange (7b). Here, the position of the locking protrusion (11) is also determined in advance so that it will be in the above-mentioned state. Next, a screw hole (15) is aligned with the screw hole (10) and drilled in the rising piece (13) in advance, and a tightening screw (16) is inserted into the screw hole (10).
Insert and tighten. At this time, the pressure contact part (
12a) is pressed against the inclined surface of the rear end of the locking protrusion (11). In this way, the compressor base (6) is fixed to the leg angles (7) at its front and rear parts.

This reduces the strength of the intersection of the trailing edge flange (7a) and the lower edge flange (7b) caused by forming the notch (11).
13), so that the main body (1) is sufficiently protected against the mechanical impact of falling nodes due to unexpected accidents such as during transportation, and the plate thickness of the pedestal angle (7) can also be reduced. become.

In this embodiment, the trailing edge flange (7a) and the lower edge flange (
7b) was constructed with a stand leg angle (7), but the rear and lower edges of both side walls (2a) (2a) of the outer box (2) were bent toward the machine room (4) to form both flanges. It's okay to do that. Finally, the rising piece (13) is attached to the trailing edge flange (7a).
A screw (16〉) was used to secure the screw, but other screws may be used.

According to the present invention, the compressor base can be easily inserted by simply tilting the outer box forward. That is, during the insertion operation, the front end is supported and guided by the lower edge flange in the engagement claw, so that the insertion of the base, which is normally heavy, can be performed very easily. Furthermore, since the protrusion is inserted into the through hole, there is no need to press the base against the outer box during the fixing operation with screws or the like, which further improves work efficiency. Further, according to the present invention, the compressor base has an engaging claw at its front portion that is crimped to the inclined surface formed at the rear end of the locking protrusion of the lower edge flange provided on the outer box. At the rear, the protrusion of the rising piece is inserted into the through hole of the trailing edge flange provided on the outer box and fixed with a fastener, so it can be securely fixed to the outer box, and the machine at the bottom of the back of the outer box can be securely fixed. This will also strengthen the physical strength.
