DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator.

[0002]

2. Description of the Related Art FIG. 6 shows a structure for mounting a power supply printed circuit board for controlling a refrigerator.

In this case, a housing 115 for a power supply printed circuit board is provided at the upper rear end of a main body 111 in which an outer box 112 and an inner box 114 are combined. A large part of the back surface of the outer box 112 which is fully open is covered by a rear plate 116, and
15 is fitted with a frame 121 after molding. At the center of the rear frame 121, a storage recess 129 is provided, on which a power supply printed circuit board 128 is mounted via a reinforcing plate 118, and this is covered with a rear cover 130.

The reinforcing plate 118 is attached when the power supply printed circuit board 128 ignites by any chance.
This is for the purpose of preventing the spread of fire to 1.

[0005]

However, such a mounting structure of the power supply printed circuit board 128 requires the reinforcing plate 11.
8 is costly and poor in manufacturability. Also, the rear frame 124
Also needs to be separately manufactured for each width of the refrigerator, which also increases the cost.

Accordingly, the present invention has been made in view of these problems, and provides a refrigerator which can eliminate the reinforcing plate.

[0007]

According to the present invention, there is provided a refrigerator having a housing for a power supply printed circuit board at an upper rear end of a main body comprising an outer box and an inner box, wherein the outer box is provided below the housing. A rear plate extending from the upper end of the rear plate into the storage portion to form a reinforcing plate, and two left and right covers are mounted on upper portions of upper and lower surfaces of the outer box located on both sides of the reinforcing plate. Attach the power supply printed circuit board to the board,
The power supply printed circuit board is covered with a rear cover.

[0008]

[Operation] In the refrigerator described above, the rear surface of the outer box is covered with the rear plate, and the upper rear surface of the outer box located on both sides of the reinforcing plate extending from the upper end of the rear plate is covered with left and right covers.
Next, a power supply printed circuit board is attached to the reinforcing plate, and this is covered with a rear cover. Thereby, the power supply printed circuit board can be attached to the storage section at the upper end on the rear surface of the outer box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 10 denotes a refrigerator, and its main body 11
Is formed by an outer box 12 and an inner box 14. Inner box 1
The upper end of the rear surface of the rear case 4 is inclined forward, and has a space between the rear surface of the outer case 12 and the power supply printed circuit board storage unit 15.

Reference numeral 16 denotes a rear plate that covers the back of the outer box 12. The rear plate 16 is sized to cover the back surface of the outer box 12 except for the storage portion 15. From the center of the upper end of the rear plate 16,
A reinforcing plate 18 that extends forward through the step 20 extends. The partition part 22 extends further upward from the upper end of the reinforcing plate 18, the upper part of the partition part 22 is bent rearward, and the engaging part 23 extends forward from the rear end.

Reference numerals 24 and 26 denote left and right covers attached to the upper rear part of the outer box 12. That is, these covers 24 and 26 are arranged on both sides of the reinforcing plate 18.

The cover 24 on the right side in the figure is formed by molding, and a concave portion for a handle 25 is formed on the rear surface of the main body 24a. The left side surface of the main body 24a forms an engagement surface 24b for fitting with the reinforcing plate 18. The engagement surface 24b forms a right side surface of the power supply printed circuit board storage unit 15. A lateral flange 24c is provided on the outer periphery of the engagement surface 24b. A rear flange 24d is provided on the upper and right sides of the main body 24a, and engages with the rear edge of the outer box 12. Also,
The left cover 26 in the figure has a structure symmetrical to the cover 24 and has a main body 26a, a handhold 27, an engagement surface 26b, a lateral flange 26c, and a rear flange 26d.

Reference numeral 28 denotes a power supply printed circuit board of the refrigerator 10. Reference numeral 30 denotes a rear cover that covers the power supply printed circuit board 28.

Next, a method of attaching the power supply printed circuit board 28 will be sequentially described.

The rear plate 16 is attached to the opening on the back surface of the outer case 12, and the front end of the engaging portion 23 is engaged with the upper edge of the opening. In this case, the reinforcing plate 18 forms a front wall of the power supply printed circuit board storage unit 15.

The right cover 24 and the left cover 26 are
Arranged on both left and right sides of the reinforcing plate 18, and the horizontal flanges 24c, 26
c is placed on both sides of the reinforcing plate 18, and the rear flanges 24d,
26d is attached to the back edge of the outer box 12 with screws. In this case, the engagement surfaces 24b and 26b form both side walls of the power supply printed circuit board storage unit 15.

The power supply printed circuit board 28 is
Are attached to the reinforcing plate 18 with screws 34. The collar 32 functions to insulate the power supply printed circuit board 28 from the reinforcing plate 18.

The rear cover 30 is connected to the step portion 20 of the reinforcing plate 18.
And mounted with screws 36 so as to cover the power supply printed circuit board 28. Thus, the rear cover 30 forms a rear wall of the power supply printed circuit board storage unit 15.

Outer box 12, rear plate 16, two covers 2
Urethane, which is a heat insulating material, is injected into a space formed by the inner box 4 and the inner box 14 to perform urethane foaming.

In the refrigerator 10, the power supply printed circuit board 28 can be mounted without requiring a separate reinforcing plate for preventing the spread of fire, so that the cost can be reduced. Further, since the covers 24 and 26 are attached from both sides of the reinforcing plate 18, the same covers 24 and 26 can be used for refrigerators having different widths. Therefore, only one type of die is required, and the cost is further reduced.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, the method of attaching the power supply printed board 28 and the reinforcing plate 18 is different.

That is, the flanges 2 of the covers 24 and 26
Two fixing members 38 and 40 are provided above and below 4c and 26c by integral molding. The upper fixing member 38 is a stepped flat plate, and the lower fixing member 40 has a U-shaped cross section, and holds the power supply printed circuit board 28 between them.

[0024]

According to the refrigerator of the present invention, since the reinforcing plate is extended from the rear plate of the outer box, it is not necessary to attach a reinforcing plate for preventing the spread of fire to the refrigerator body when the power supply printed circuit board is fired. Cost is reduced.

Further, since the left and right covers are attached to both sides of the reinforcing plate, it is not necessary to manufacture a separate mold every time the width of the refrigerator is different as in the prior art, which greatly increases the mold manufacturing cost. Reduction.
