Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to fixing the central shaft of a cooking appliance with a switch lever used in general households.

Conventional structure and its problems Conventionally, in fixing the center shaft of a cooker having this type of switch lever, as shown in Fig. 1,
An operation panel 2 is provided on the main body 1 of the cooking device, and a lever 4 for turning on and off a power switch 3 is provided at the bottom of the operation panel 2.
A frame 5 was provided for fixing the components and the like to the operation panel 2. Further, 6 is fixed to the frame 5 by a shaft, and the lever 4 is generally formed to rotate when the power switch 3 is turned on or off.

However, with this configuration, when fixing the shaft 6 to the frame 5, both ends may be bent or caulked, which may impede the rotation of the lever 4 during this process. In addition, since there are many parts during assembly, it is difficult to insert the shaft 6 into the holes of each part, so it is necessary to use a jig or the like to assemble, resulting in the problem that assembly takes time.

Purpose of the Invention The present invention solves these conventional problems, improves assembly efficiency, eliminates distortion due to machining, and provides a cooking method in which the shaft can be securely fixed without using auxiliary tools such as jigs. It provides equipment.

Configuration of the Invention In order to achieve the above object, the cooker of the present invention has the following features:
The base has a bearing part, a shaft that fits into the bearing of this base, and a lever that rotates around this shaft.The base has a bearing fitting part that fits the shaft. When the base is fixed to the main body after being fitted onto the lever, the shaft is held by the burring part of the main body, so that the shaft cannot be attached or detached.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 to 4, reference numeral 7 denotes a base fixed to the cooking device main body 8, on which a control circuit board and the like can be attached. A shaft 9 is fitted into the shaft hole 11 of the rice cooking lever 10 and the bearing portion 12 of the base 7, and has a diameter determined so that the rice cooking lever 10 can rotate. Further, the shaft 9 is bent from the middle, and is provided so that the fitting portion 3 of the base 7 and one end 14 of the shaft 9 are fitted. The rice cooking lever 10 is a push plate part 1 that can turn on and off a power switch 15 on the control circuit board, etc.
6, and also has the aforementioned shaft hole 11 that freely rotates around the shaft 9. 17 is a screw that fixes the base 7 to the main body 8.

Reference numeral 15 mentioned above is a power switch, which is turned on and off by the push plate part 16 of the rice cooking lever 10. Reference numeral 18 denotes a burring portion formed on the main body 8 opposite to the fitting portion 13 of the base 7.

In the above configuration, temporarily fixing the shaft 9 to the base 7 and preventing the shaft 9 from coming off when fixing the base 7 to the main body 8 will be explained.

What is shown in FIG. 2 is an exploded perspective view of this embodiment, and FIG. 3 is a perspective view after assembly. At this time, one end 14 of the shaft 9 is fitted into the fitting part 13 of the base 7 and temporarily fixed.

Furthermore, as shown in FIG. 4, by fixing the base 7 with the screws 17, the burring part 18 of the main body 8 comes into contact with the shaft 8, so that the base 7 can be fixed to the main body 8.
The shaft 9 cannot be removed unless it is removed further.

In the above embodiment, the shaft 9 is bent and brought into contact with the burring portion 18 of the main body 8, but the shaft 9 may be straight and the burring portion 18 may be enlarged and brought into contact with the shaft 9. The point is that after the base 7 and the shaft 9 are temporarily fixed, the base 7 is fixed to the main body 8 so that the shaft 9 cannot be removed.

Effects of the Invention As is clear from the above embodiments, the present invention provides a burring part on the main body to prevent it from coming off, so that the shaft can be reliably temporarily fixed to the base, which dramatically reduces the number of processing and assembly steps. Distortion can be eliminated, and the defective rate due to processing can be significantly improved.

In addition, in the past, many parts were stacked and inserted into the shaft hole, but now they only need to be inserted into the shaft hole of the rice cooker lever, and it can be assembled without making jigs and tools, making the work faster. This makes it possible to reduce the defective rate during processing and improve assembly efficiency.
