Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric refrigerator, and more particularly to a defrosting water treatment device installed in a machine room.

[0002]

2. Description of the Related Art As shown in FIG. 4, a machine room 1 in which a compressor 1a and an evaporation tray 10 are arranged above the compressor 1a is provided in the lower rear portion of an electric refrigerator. A handle 11 may be attached to the upper part of the machine room 1 or the upper end of the back plate for assisting movement after the refrigerator is installed. However, the handle 11 has a method in which a burring hole 13 is formed in the back plate 12, and the handle 11 is fixed by being locked in the burring hole 13 to prevent the heat insulating material 14 constituting the inside of the back plate from leaking. Was necessary, which was a bottleneck in reducing the number of assembly steps and the number of parts. The evaporating dish 10 is removably supported by the support plates 15 having guide grooves facing each other, but since the evaporating dish 10 has the same height at the insertion position and at the steady position, it is disposed below. There is a structural problem that the height of the compressor and the machine room 1 is increased.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and a handle for movement assistance is formed integrally with another member to reduce the number of parts of a refrigerator and reduce the cost. Moreover, the support plate structure of the evaporation dish is improved to reduce the height dimension of the machine room.

[0004]

In order to solve the above-mentioned problems, the present invention is characterized in that a handle in the front-rear direction is integrally formed on the support plate. Further, the guide grooves are provided in two stages into which the front and rear bosses are respectively inserted, and the guide grooves have a curved shape that rises rearward so that the stationary position of the evaporation dish is higher than the insertion position. It is characterized by what you have done.

[0005]

With the above construction, in the electric refrigerator according to the present invention, the handle for movement assistance is integrally formed on the support plate of the evaporation tray by resin molding, so that the number of parts can be reduced and the member Can lead to cost reduction. Further, the height dimension of the machine room can be reduced.

[0006]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a front view of a lower rear portion of the refrigerator, and FIG. 2 is a sectional view thereof. A machine room 1 is provided in the lower part of the back surface of the main body with a bottom plate 2 having a high stepped rear portion as an inner wall surface. A compressor 1a is placed in the machine room 1 and above the compressor 1a. The evaporation tray 4 is supported by a pair of support plates 5 and 5 so that it can be inserted and removed freely.

As shown in FIG. 3, the support plate 5 is a member in which a support portion and a grip portion of the evaporation dish are integrally formed by resin molding, and the support plates 5 and 5 are formed as a pair of left and right symmetrical members. . FIG. 3 illustrates one of them. The flat plate-shaped mounting portion 5a is integrally formed with a tubular grip portion 6 having a recess extending in the front-rear direction, and an opening portion 6a of the grip portion 6 is opened on the mounting portion 5a. , The mounting portion 5
A screw insertion hole 5c is formed at both upper ends of the opening 6a of a. An upper plate portion 8 is continuously formed so as to be connected to the upper surface of the handle portion 6, and locking claws 5b having notches 5d formed at the lower ends thereof are projected on both rear sides of the upper plate portion 8. A support plate 7 is formed so as to hang downward from the upper plate portion 8. On one side of the support plate 7, guide grooves 7a and 7d are formed vertically with the back surface reinforced by ribs. The open ends of the guide grooves 7a and 7b open vertically in the front surface of the support plate 7, and the grooves 7a and 7b are formed as curved inclined surfaces that rise toward the rear side, and the inner sides thereof are locked. The portions 7c and 7d are formed as downward recesses. The locking portions 7c and 7d are formed to be the same in the height direction and to be located above the opening end, so that the stationary position for supporting the evaporation dish 4 is above the insertion position of the evaporation dish. Is located in.

The evaporation tray 4 is a container for defrosting water, which is made of resin and has a flat rectangular box shape. The evaporation tray 4 is provided with a cover 4a on the front surface, and bosses 4b are symmetrically integrated outward on the left and right side walls. The boss 4b is bent downward to prevent the boss 4b from falling off. The rear wall is formed with a spherical recess 4c which serves as an escape portion from the compressor 1a when the evaporation tray 4 is housed in the machine room 1 of the refrigerator, and a reinforcing rib 4d is formed on the bottom surface. It stands upright.

The bottom plate 2 forming the inner wall surface of the machine room 1.
Slit holes 2a corresponding to the locking claws 5b of the supporting plate 5 are formed on both sides of the upper surface of the support plate 5, and the rear plate 3 above the machine chamber has screw holes 3a corresponding to the screw insertion holes 5c on both sides. Has been drilled.

The mounting procedure and operation with the above configuration will be described. The locking claws 5a of the support plates 5 and 5 are inserted into the slit holes 2a of the bottom plate 2 and slid backward to fit and lock the notches 5d into the steel plate of the bottom plate, and the screw insertion holes of the mounting portion 5 are also provided. 5c, a screw 9 is inserted and screwed into a screw hole 5c of the rear plate to form the support plates 5 and 5 in which the grip portions are integrated.
To fix. Next, the boss 4b at the rear of the evaporation dish 4 is inserted into the guide groove 7b, and the boss 4b at the front is inserted into the guide groove 7a, and are slid rearward to engage with the recesses of the engaging portions 7d and 7c. As a result, the evaporating dish 4 is placed at the steady position. As described above, the locking portions 7d and 7c are positioned higher than the opening end, the evaporation tray 4 is supported at a high position, and the escape dimension from the compressor 1a is large, so It has been miniaturized. After the refrigerator is installed, if the installation position is to be slightly modified, the position of the main body is corrected by moving the refrigerator by holding the handle portion 6 integrally formed with the evaporation tray guide 5. be able to.

[0011]

As described above, in the electric refrigerator according to the present invention, the support plate of the evaporating dish is integrally formed with the handle for movement assistance, which leads to a reduction in the number of members.
The number of assembling steps of the refrigerator can be reduced and the cost can be reduced, and the structure of supporting the evaporation tray at a position higher than the insertion position can improve the effective space of the machine room.
