Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching a compressor base on which an electric compressor incorporated in a refrigerator or the like is mounted, and particularly to a method that facilitates the attachment work.

Conventionally, for example, in refrigerators,
As shown in Publication No. 75693, 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 is poor because the board must be held in close contact with the refrigerator while the rear end or front end of the board is being screwed on.

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

1 is the refrigerator itself, and Figure 1 shows the back.
Reference numeral 2 is an outer box made of, for example, a steel plate, and a machine room 4 is formed at the lower part of the back for housing an electric compressor 3, etc. included in the refrigeration cycle, and 5 is also included in the refrigeration cycle. In the embodiment, it is provided on the back of the main body 1. Further, 6 is a compressor base on which the compressor 3 is placed and fixed.

Now, in this case, in order to reinforce the outer box 2, a substantially L-shaped reinforcing angle 7 is fixed to the machine compartment 4 portion of both side walls 2a of the outer box 2 along its lower and rear edges by spot welding or the like. ing. The reinforcing angle 7 has a trailing edge flange 7a and a lower edge flange 7b extending toward the machine room 4 on its rear edge and lower edge. A corner portion where the rear edge flange 7a and the lower edge flange 7b intersect is slightly cut away to form a cutout portion 8, so that the rear end surface of the lower edge flange 7b is exposed.
A long hole 9 and a screw hole 10 are formed below the long hole 9 in the rear edge flange 7a slightly above the notch 8. Further, a locking protrusion 11 that is bent and protrudes upward is provided in the front part of the notch 8 of the lower edge flange 7a, and the rear end of the locking protrusion 11 is located in the front part of the notch 8. An inclined surface is formed that gradually increases in height toward .

Now, on the front part of both ends of the compressor base 6, there is an approximately L mark upward.
The engaging portion 12 is bent into a letter shape and faces both sides, and the engaging portion 12 has a pressure contact portion 12a whose front end portion is bent diagonally upward. Also, compressor base 6
At the rear of both ends, there are rising pieces 13 that are bent and raised.
is formed, and a tapered protrusion 14 formed by bending forward is provided at the upper end thereof.

To attach the compressor base 6 to the outer box 2, first insert the engaging claw 12 through the notch 8, and then insert the underlined flange into the gap between the engaging claw 12 and the compressor base 6. 7b and insert the engaging claw 12 into the lower edge flange 7b.
is engaged with. When the compressor base 6 is inserted forward in this state, the protrusion 14 begins to be inserted into the elongated hole 9 next. Here, the positions of the elongated hole 9 and the protrusion 14 are determined in advance so that they will be in the same position in the above-mentioned state. Thus, the rising piece 13 is the trailing edge flange 7a.
, the pressure contact portion 12a of 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, screw hole 1 in advance.
0, insert the tightening screws 16 into the screw holes 15 and 10 made in the rising piece 13, and tighten them. At this time, the pressing portion 12a of the engagement claw 12 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. As a result, the reduction in strength at the intersection of the trailing edge flange 7a and the lower edge flange 7b caused by forming the notch 8 is reinforced by the rising piece 13 of the compressor base 6, and therefore the main body 1 This provides sufficient protection against mechanical shocks such as falls due to unexpected accidents such as during transportation, and the plate thickness of the base leg angle 7 can also be reduced.

In this embodiment, the trailing edge flange 7a and the lower edge flange 7b are constructed from the base leg angle 7, but the rear edge and lower edge of both side walls 2a, 2a of the outer box 2 are bent in the machine room 4 direction. A flange may be formed. Furthermore, the rising piece 13 is finally attached to the trailing edge flange 7a.
Although the screw 16 was used to fix the screw to the screw, it is not necessary to use a screw.

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.
