Description

[Detailed Description of the Invention] (a) Field of the Invention The present invention relates to an electrical device used in a refrigerator, and particularly to an electrical device that houses a starting capacitor, an operating capacitor, etc. for a motor of a refrigeration system compressor.

(b) Prior art The starting capacitor and running capacitor for the electric motor of the refrigeration system compressor of a refrigerator are fixed in the electrical box by fixing the round starting capacitor to the electrical box with screws, while the square running capacitor is The outwardly extending fixing part is directly screwed to the electrical box. Also, if there was a fan motor for cold air circulation, the rectangular operating capacitor for that fan motor would also be fixed in the same way as the former operating capacitor.

Therefore, as the number of capacitors increases, the screw fixing process increases, and a fixing band for the round capacitors must also be provided, which is inefficient in terms of work efficiency.

(c) Purpose The present invention improves the drawbacks of the prior art, eliminates the fixing band for round capacitors, and provides a structure that allows both round and square capacitors to be supported in an electrical box without screws.

(D) Embodiment 1 is a substantially rectangular electrical box with a front opening, and an elastic piece 2 is provided in the upper part of the back wall 1A near the upper wall 1C in an arc shape extending toward the free upper end 2A and projecting forward of the back wall 1A. The vertical side wall 1B has a back wall 1.
A rectangular long hole 3 is formed in the corner with A, and the vertical side wall 1B
An approximately L-shaped second elastic piece 4 is integrally provided on the outer surface of the main body 1. One end of the elastic piece 4 is connected to the outer surface and the other end is movable along the vertical side wall 1B. The second elastic piece 4 has a protrusion 5 facing outward from the hole 3 on its free side. Reference numeral 6 denotes a starting capacitor for the electric motor of the refrigeration system compressor, which is cylindrical and has a so-called round shape.
Reference numeral 7 designates a rectangular capacitor for the motor of the compressor, and forms a fixing part 8 extending outward from one corner, and a locking hole 9 is formed in the fixing part 8. Reference numeral 10 denotes a guide piece extending rearward from the back wall 1A in the vicinity of the hole 3, and serves to limit the lateral vibration of the movable range of the elastic piece 4. Reference numeral 11 denotes a capacitor for operating the cold air circulation fan motor, which has the same shape as the capacitor 7 and has the same mounting structure as the capacitor 7, as will be described later.
12 is a timer device for defrosting control.

In this configuration, the round capacitor 6 uses the elastic force of the elastic piece 2 which has a substantially same arc shape as the outer surface of the round capacitor 6.
It is held between the back wall 1A and the upper wall 1C of the box body 1. On the other hand, the square capacitors 7 and 11 are arranged along the back wall 1A and the vertical side wall 1B inside the box body 1, and the elastic pieces 4 are deformed as shown in FIG. With the protrusion 5 extending outside the body 1 and fitted into the hole 9 by the elasticity of the second elastic piece 4, the rear surface of the fixing part 8 is in contact with the elastic piece 4, and the front surface is in contact with the edge of the square hole 3. By holding the square capacitor 7
is retained.

(e) Effects A round capacitor is held securely between the back wall and top wall of the box and an arc-shaped elastic piece that is approximately the same as the outer surface of the round capacitor, making effective use of the corner of the box, while a rectangular capacitor is With the protrusion of the second elastic piece engaged with the hole in the fixing part, the fixing part is held between the second elastic piece and the edge of the hole in the vertical side wall of the box body, ensuring secure retention. Stable support can be achieved by mounting using each wall corner. Further, since no screws are used for each capacitor, and no fixing band is required, the installation work is improved.
