Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a spring structure used for opening and closing a lid of a rice cooker.

[Prior Art] The lid of the rice cooker is equipped with two springs at its end for convenient opening and closing of the lid. FIG. 2 shows a spring structure attached to the lid of the rice cooker, (a) is a plan view, (b) is a side view, in which 1 is a lid of the rice cooker, 2 is a spring, 3 is a spacer,
3a is its shaft hole, 4 is a shaft, and 5 is a bracket.

As shown in the figure, a coiled spring 2 holds a cylindrical spacer 3 inside, and mounts both ends of a shaft 4 which penetrates the central portion of the spacer 3 on a bracket 5 and is attached to the lid 1. ing. When assembling the lid, the left and right springs are attached to the lid one by one.

[Problems to be Solved by the Invention] By the way, since the above-mentioned conventional spacer has a cylindrical shape and its outer peripheral portion has many contact portions with the inner surface of the spring, when it is used for a long time, the life of the spring is affected by friction. In addition, since the spacer is thick, many materials are used and the cost is high.

Also, since the left and right springs have their respective shafts, when assembling, one shaft must be fixed with the lid and the other hand must be used only to pass the shaft through one spring and then the other spring. The work becomes unstable.

The present invention has been made in order to solve the above problems in the conventional rice cooker, and is to provide a spring structure which is low in cost, has a spacer with a small friction with a spring, and is easy to assemble. .

[Means for Solving the Problems] In order to achieve the above object, in the spring structure of the lid of the rice cooker according to the present invention, the shape of the spacer is made into a cross shape so that the material used can be saved and There is one shaft for each of the two springs.

[Operation] Since the shape of the spacer is changed from the conventional cylindrical shape to the cross shape, the material used can be reduced. Further, since the left and right springs have a single shaft in common, the work of mounting the spring on the lid becomes easy.

[Embodiment of the Invention] FIG. 1 shows an embodiment of the present invention. (A) is a perspective view of a spacer, (b) is a plan view of a spring mounting portion, and (c) is a side view thereof. Reference numerals 2, 5 are the same as or equivalent to the conventional rice cooker, 10 is a spacer, 10a is a shaft hole, and 11 is a shaft.

As shown in the figure, in the spring structure according to the present invention, the outer diameter of the spacer is the same as that of the conventional cylindrical spacer, but the shape is a cross shape. Further, the number of the shaft 11 is one for both the left and right springs.

Since the plastic spacer 10 has a cross shape, the material used can be saved and the contact portion with the inner diameter of the spring can be reduced. Further, since there is only one shaft 11 for both the left and right springs, it is possible to assemble the left and right spring structures at once when assembling the spring structure.

[Effect of the Invention] In the spring structure of the lid of the rice cooker according to the present invention, the spacer is formed in a cross shape and the shaft is provided for each of the two springs on the left and right sides. I was able to name it.

(1) Since the contact portion between the spacer and the spring is small, the life of the spring is not shortened due to friction even after long-term use.

(2) Since the material used for the spacer is small, the cost is reduced.

(3) When assembling the spring structure, the left and right two springs of the lid can be assembled at once, which facilitates the assembly work.

[Brief description of drawings]
