Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a switch base of a rice cooker.

[Prior Art] Rice cookers, which heat and cook rice using electric power, have become widespread nationwide and have become an indispensable appliance in the kitchen of each household. For that reason, the manufacturers' enthusiasm for technological development and cost reduction is wonderful, and the target of development extends to the small end parts that make up the rice cooker.

Fig. 2 is a sectional view of the switch base of the rice cooker.
FIG. 3 is a perspective view of the back surface of the switch base, in which 1 is a base, 2a is a rice cooking button, 2b is a heat retaining button, 3a and 3b are button holders, 4a and 4b are pins, and 5 is a spring.

As you can see in the figure. The switch base attached to the body of the rice cooker has a rice cooking button 2a and a warming button 2b attached via a spring 5, so that the user of the rice cooker can press the button 2a or
By pressing 2b, the pin 4a or 4b presses the respective switch lever, and the rice cooker performs the operation of cooking rice or keeping heat.

[Problems to be solved by the invention] By the way, the switch base is symmetrical from the surface and the button holders 3a and 3b have the same shape. Therefore, when assembling the rice cooker, the switch base is attached to the body of the rice cooker. When mounting, the switch base may be mounted on the left and right. In that case, the rice cooker 2a and the heat retention button 2b have different lengths of the pins 3a and 3b, so that the rice cooker does not operate normally and becomes a defective product. As a result, it has to be reassembled again, which requires much labor and cost, so that countermeasure has always been a problem.

The present invention has been made to solve the above problems,
The purpose of the present invention is to provide a rice cooker in which the switch base cannot be attached to the left and right hands when the rice cooker is assembled.

[Means for Solving the Problems] In order to achieve the above object, the present invention forms a left-right asymmetrical fitting portion on the back surface of the switch base and the switch base mounting portion of the rice cooker body.

[Operation] When the switch base is mounted on the rice cooker case, the switch base is fitted and fitted. Since the fitting portion is formed asymmetrical to the left and right, and the fitting portion does not fit when mounted on the left and right, the fitting portion is not mounted on the left and right.

[Embodiment of the Invention] FIG. 1 is a perspective view of the back surface of a switch base according to an embodiment of the present invention, in which 1 to 4a and 4b are the same or corresponding parts as a conventional rice cooker, and 10 is a recess. .

As shown in the figure, asymmetrical recesses 10 are formed on the back surface of the switch base, and a protrusion that fits into the recess 10 is formed on the switch base mounting portion of the case of the rice cooker.

Since the recess 10 is formed asymmetrical to the left and right, when the switch base is mounted on the rice cooker case, it will not fit properly into the recess of the switch base and the protrusion of the case. It is not installed without permission.

In addition, in the present embodiment, the fitting portion between the switch base and the case is constituted by the concave portion and the convex portion formed in each of the above, but is not limited to this method,
Other methods may be used.

In addition, although the present embodiment shows an example in which the switch base is mounted on the body of the rice cooker, the mounting position of the switch base is not limited to the body.

[Advantages of the Invention] The present invention includes a switch base mounted on a case of a rice cooker,
Since the left and right asymmetrical fitting parts are formed on the case where the switch base is mounted, and when the switch base is mounted on the case, the fitting part is fitted and mounted, so that the switch base is mounted on the left and right sides. It is now possible to completely prevent the generation of defective products.

[Brief description of drawings]

FIG. 1 is a perspective view of a switch base according to an embodiment of the present invention, FIG. 2 is a partial sectional view of a rice cooker, and FIG. 3 is a perspective view of a conventional switch base. In the figure, 1 is a base, 2a and 2b are buttons, 3a and 3b are button holders, 4a and 4b are pins, and 10 is a recess. The same reference numerals in the drawings indicate the same or corresponding parts.
