Description

[Detailed Description of the Invention] The present invention relates to a storage box fixing device for electronic components used in electric rice cookers, electric jar rice cookers, etc., and is particularly designed to securely fix the storage box.

Recently, electric rice cookers and electric jar rice cookers use electronic circuits to notify the completion of rice cooking and electronic circuits to accurately control the amount of heat generated, and electronic components such as transistors that make up the above electronic circuits. is easily affected by heat, so it is desirable to keep it away from the heat source.

However, in the above-mentioned products, it is difficult to secure storage space, and the products are often mounted on the external bottom surface of the frame.

Electronic components mounted in this way are considered to be at the lowest temperature due to the nature of the product, but since the frame is generally made of metal and the heating plate is close, the maximum temperature reaches around 70 degrees. Occasionally, the storage box may become deformed.

The present invention was made to improve the above-mentioned drawbacks, and will be explained below based on the drawings. 1 is a cylindrical frame with a bottom, and a slightly recessed step 2 and an upwardly recessed recess 3 are formed on the outer bottom. are doing.

Reference numeral 4 denotes a semicircular synthetic resin storage box integrally molded with support legs 5, which stores electronic components 6 such as transistors, and is composed of an upper plate 7 and a lower plate 8.

The electronic component 6 is fixed to a board 9 and has a mounting boss 10.
．． It is sandwiched between the upper plate 7 and the lower plate 8 via 10.

11 is a screw for fixing the storage box 4.

12. Support legs 12 are fixed to the outer bottom of the frame 1 at predetermined intervals.

Next, to describe the assembly order and operation, first, as described above, the board 9 is sandwiched between the upper plate 7 and the lower plate 8 via the mounting bosses 10 and 10, and the assembly of the storage box 4 is completed. A part of the box 4 is connected to one support leg 5 by means of screws 11.
is fixed to the outer bottom of frame 1, and the other part (not shown) is fixed to the outer bottom of frame 1.
Fixed by

At this time, the storage box 4 is located in the recess 3, and the flat surface F contacts the step 2 of the frame 1 as shown in FIGS. 2 and 3.

Therefore, even if the temperature of the frame 1 rises and the flat surface F of the storage box 4 deforms in the direction of the arrow in FIG. 2, this is prevented by the step 2.

In addition, even if an impact force is applied from the outside of the support leg 5 due to a fall, that is, from the direction of arrow B in FIG.
Damage and deformation of the storage box 4 are prevented by contact with the storage box 4.

As described above, in the present invention, the flat surface of the storage box made of synthetic resin for storing electronic components is fixed by abutting against the step provided at the outer bottom of the frame.
Since the support legs of the storage box are integrally molded, the number of parts is reduced and installation is simple, and since it is fixed to the outer bottom of the murem, it is relatively far away from the heat source and is unlikely to be affected by thermal effects. Needless to say, since the flat surface of the storage box is brought into contact with the step of the frame, even if a force is applied that would cause the storage box to deform, the step will prevent it from deforming.

In addition, the step can reinforce the outer bottom and is preferably used as a guide for water flowing into the frame.
