Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator in which an electrical component unit is provided in a machine room.

[0002]

FIGS. 6 to 8 show an example of a conventional refrigerator. A machine room 2 is provided in a lower portion on the rear side of the refrigerator main body 1, and a compressor 3 is provided in the machine room 2, and an electric component unit 4 is provided near an inner surface of the machine room 2. ing. As shown in FIGS. 7 and 8, the electrical component unit 4 has a substantially rectangular case 5 and a vertical circuit board 6 on which electrical components used for a power supply circuit are mounted. An operation capacitor 7 for the drive motor is disposed above the circuit board 6, and a number of necessary lead wires are connected to the capacitor 7 and the circuit board 6 as needed. A bundle 8 in which lead wires are bundled is wired.

By the way, in the above-mentioned conventional configuration, as can be understood from FIG. 8, a circuit board 6 and a capacitor 7 are arranged in a plane (a vertical plane in a vertical plane). Therefore, since the bundled wires 8 are also arranged in the same plane, they become large in the vertical direction, so that the machine room 2 must be formed large in the vertical direction, which hinders an increase in the volume of the cooling chamber. There was a problem that caused it.

The present invention has been made in view of the above circumstances, and an object thereof is to reduce the size of an electrical component unit, to reduce the volume of a machine room, and to increase the volume of a cooling room. To provide a refrigerator.

[0005]

The present invention has been made by focusing on the following points. That is, although a compressor is mainly disposed in the machine room of a refrigerator, the machine room has little design freedom in the vertical and depth directions in consideration of an increase in the volume of the cooling room. However, it was found that there was some room in the space in the horizontal direction, and there was room in the degree of freedom in design.

In view of this, a first aspect of the present invention is to dispose an electrical component unit in a machine room below a refrigerator main body, wherein the electrical component unit is provided in a substantially rectangular vertical case. In addition, a circuit board is disposed in a vertical shape, and a partition member for partitioning the inside of the case in a form facing the plate surface of the circuit board is provided, and the electrical components and the bundled wires are disposed on the counter circuit board side of the partition member. Configure
This electrical component unit is arranged vertically along the inner surface of the machine room.

According to the first aspect of the present invention, in the case of the electrical component unit, the partition member is provided so as to face the plate surface of the vertical circuit board. Since the electrical components and the bundled wires are arranged on the circuit board, the partition member, the electrical components and the bundled wires are arranged side by side on the surface of the circuit board, and as a result, the case needs to be enlarged in the vertical direction. Therefore, it is possible to contribute to a reduction in the size of the machine room in the vertical direction, thereby contributing to an increase in the volume of the cooling chamber. Further, since the circuit board is separated from the electrical components and the bundled wires by the partition member, good electrical insulation can be achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 and 5
In the lower rear part of the refrigerator body 11, a machine room 12
Are formed. The machine chamber 12 is provided with an evaporating dish and the like, not shown, including the compressor 13. An electrical component unit 14 is provided on the inner surface of the machine room 12 so as to extend vertically.

The case 15 of the electrical component unit 14 is
It has a vertical shape and includes a rectangular container-shaped main body case 16 and a rectangular container-shaped cover case 17. As shown in FIGS. 1 and 2, a large number of protrusions 18 for arranging substrates are formed on the inner surface of the main body case 16. The circuit board 19 is screwed and fixed such that its end is disposed on the projection 18. Further, inside the case 15, a partition plate 20 serving as a partition member is provided in a form facing the plate surface 19 a of the circuit board 19.
5 are provided to partition the inside. Although not shown, the circuit board 19 mounts electric components constituting a power supply circuit.

At the end of the partition plate 20, a wall portion 20a is formed at the end portion. The wall portion 20a comes into contact with the inner peripheral surface 16a of the main body case 16 and the partition plate 20 itself shown in FIG. The partition plate 20 is configured to stop the movement in the up / down direction and the front / depth direction, and the partition plate 20 is pressed by the receiving portion 16b formed in the main body case 16 and the cover case 17, It is stopped in the left-right direction in FIG. Further, the surface of the partition plate 20 opposite to the circuit board 19 is provided with a capacitor mounting portion 2.
1 are formed, and the bundled wire attaching portions 22 and 23 are formed. Notches are formed in the partition plate 20 for bundled wiring.

The capacitor mounting portion 21 has a substantially U-shaped wall portion 21a and a claw portion 21b.
An operation capacitor 24 (electrical component) of the drive motor of the compressor 13 is fitted and prevented from being detached from the capacitor mounting portion 21. Further, the bundle attachment portions 22 and 23 are configured to have a pair of claw sandwiching plate portions 22a and 23a, and a part of the bundle 25 is fitted to these bundle attachment portions 22 and 23. It is secured and attached. This bundled wire 25 is connected to the circuit board 19 via a connector and also to the capacitor 24. Most of the bundled wire 25 is formed on the surface 2 of the partition plate 20 opposite to the circuit board 19.
0b.

In the electrical component unit 14, the partition member 21 and the capacitor 2 are disposed in the case 15 in the horizontal direction of the plate surface 19a of the vertical circuit board 19.
4 and a bundle 25 are arranged side by side. Therefore, it is not necessary to enlarge the case 15 in the vertical direction, and it is possible to contribute to a reduction in the size of the machine room 12 in the vertical direction, thereby contributing to an increase in the volume of the cooling chamber. In addition,
Although the electronic unit 14 becomes larger in the lateral direction, the machine room 12
There is no problem because there is room in the horizontal direction. In addition, since the circuit board 19 is separated from the capacitor 24 and the bundled wire 25 by the partition plate 21, electrical insulation can be satisfactorily achieved. The partition member is not limited to the above-described partition plate 20, and the shape and the like may be appropriately changed. The electrical component is not limited to the capacitor 24, and may be, for example, a transformer.

As is apparent from the above description, the present invention has a structure in which the electrical component unit is disposed in the machine room. The size of the cooling chamber can be increased, and the capacity of the cooling chamber can be increased, and the electrical insulation of the electrical component unit can be improved.
