Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a lid device for a rice cooker used in general households.

BACKGROUND OF THE INVENTION A conventional lid device for a rice cooker of this type is disclosed in, for example, the Japanese Utility Model Opening System published in 1983-
As shown in Japanese Patent No. 31320, it had a structure as shown in FIG.

That is, in FIG. 3, 1 is an inner lid that covers the opening of the inner pot 2, 3 is a protrusion provided on the outer lid 4, and 5 is attached to the inner lid 1 by fitting, and the outer lid The protrusion 3 of the outer cover 4 is inserted into the inner cover holder elastically, and the protrusion 3 of the outer cover 4 penetrates the inner cover 1 via the inner cover holder 5.
It held the inner lid 1.

Problems to be Solved by the Invention However, in such a conventional configuration, since the protrusion 3 passes through the inner cover 1, when the inner cover 1 is moved diagonally when the inner cover 1 is attached or removed, Force is applied directly to the protrusion 3, and as a result, a large stress is applied to the root 3a of the protrusion 3, so there is a risk that the protrusion 3 of the outer lid 4 will deteriorate during long-term use. In addition, when the inner lid 1 is attached, a convex portion is formed by the protruding portion 3, which causes a problem in that concentrated dripping of dew occurs along the convex portion during heat retention.

The present invention is intended to solve these problems, and aims to protect the protrusion by reducing the stress applied to the base of the protrusion, and to prevent concentrated dripping of dew during heat retention. It is.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has provided that the lower end of the protrusion of the outer cover, which elastically fits into the inner cover holder that is attached to the inner cover by fitting, is positioned above the inner cover. The bottom of the inner lid holder closes the opening of the inner lid and has a flat shape.

Function According to the above structure, even if the inner cover is moved diagonally when the inner cover is attached or removed, the force will not be directly applied to the protrusion of the outer cover, and the inner cover holder will expand elastically and move the outer cover. The stress applied to the base of the protrusion is reduced, and as a result, the protrusion can be protected, and the bottom of the inner lid holder that closes the opening of the inner lid can be removed. Since it is configured to be flat, concentrated dripping of dew during heat retention can be prevented.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, 6 is a cylindrical rice cooker main body, and the upper opening of this rice cooker main body 6 is covered with an outer lid 7. As shown in FIG. Reference numeral 8 denotes a removable inner pot that is housed inside the rice cooker main body 6. The opening of the inner pot 8 is covered with an inner lid 9, and the inner lid 9 has a protrusion provided on the outer lid 7. Part 1
The inner lid holder 11 into which the holder 0 is elastically fitted is attached by fitting, and the lower end 1 of the protrusion 10 of the outer lid 7
As shown in FIG.
a closes the opening 9a of the inner lid 9 and is configured to have a flat shape. With such a configuration, even if the inner cover 9 is moved diagonally when the inner cover 9 is attached or removed, the force is not directly applied to the protrusion 1o of the outer cover 7, so that the base of the protrusion 10 It is also possible to reduce the stress applied to the object. Inner lid holder 1
Since the bottom portion 11a of No. 1 is flat, it is possible to prevent concentrated dripping of dew during heat retention.

Effects of the Invention As described above, according to the present invention, the lower end of the protrusion provided on the outer cover is configured to be located above the inner cover, and the bottom of the inner cover holder that closes the opening of the inner cover is configured. Since the shape is flat, even if the inner cover is moved diagonally when the inner cover is attached or removed, the force will not be applied directly to the protruding part of the outer cover. It is possible to reduce the stress applied to the base of the protruding part when attaching and removing the lid, thereby protecting the protruding part and also preventing concentrated dripping of dew when keeping warm. It is.
