Abstract

PURPOSE:To reinforce a lid body without adding parts by providing both a shaft with a specified length which is located at the rear of the lid body and supports the lid body rotatably by a main body of a rice boiler, and contact parts which contact both ends of this shaft on the side of the lid body. CONSTITUTION:A shafting part 8 is formed by mounting a shaft 8a through both a bearing 8b for a lid and bearings 8c for a main body, and the shaft 8a is over one-third of the width of a lid body 2 in length. A cover 9 covering the shafting part 8 provides catches 9a at both the upper and lower edges, and is fitted by these catches 9a being inserted into catch-holding holes 7a opened on both the upper and side faces of the rear of the lid body 7. Its contact part 9b support both ends of the shaft 8a located inside this cover 9. When rice is boiled, though a high pressure is applied to the lid body 7 and tries to lift the lid body 7 in the direction of arrows, the shaft 8a holds back this lifting force and prevents the lid body from being deformed since the contact parts 9b contact with the shaft 8a.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a rice cooker, particularly to prevention of deformation of a lid.

[Conventional technology]

A conventional rice cooker will be explained with reference to FIGS. 4 and 5. In the figure, (11 is the rice cooker body, (2) is the lid body.

(3) is the shaft, and (4) is the screw 151 on the inner surface of the lid (2).
It is a metal reinforcing plate fixed with one strand.

Conventional rice cookers are configured as described above, and when cooking rice.

High pressure from inside the rice cooker body +11 is applied to the lid body (2), and a force acts to push the lid body (2) up in the direction of the arrow in Figure 4, and the reinforcing plate (4) prevents this. There is.

[Problem to be solved by the invention]

In the conventional rice cooker as mentioned above, a reinforcing plate (4) must be provided just to reinforce the lid (2), and screws (5) are used to attach it, which reduces material and processing costs. There was a problem that the amount of water increased.

This invention was made to solve this problem, and an object of the present invention is to provide a rice cooker whose lid can be reinforced without adding any parts.

[Means to solve the problem]

The rice cooker according to the present invention includes a rice cooker main body, a lid provided on the upper side of the rice cooker main body, and a rear part of the lid with a length of 1/3 or more of the width of the lid. The rice cooker includes a shaft that rotatably supports the lid on the rice cooker main body, and an engaging portion that engages an end of the shaft with the lid.

[For production]

In this invention, the shaft prevents the lid from deforming.

〔Example〕

An embodiment of this invention will be described with reference to FIGS. 1 to 3. In the figure, (6) is the rice cooker body, and (7) is the lid.

(8) is a shaft portion, and the shaft (8th) passes through a lid bearing (8b) and a main body bearing (8c). (9) is a shaft cover that covers this shaft (8), and has tabs on the top and bottom.
(9a) is provided, and a claw receiver with the claw (9a) opened on the rear upper surface and rear side surface of the lid (7) is attached by engaging with the hole (7a). (9b) is an engaging portion that supports both ends of the shaft (8a) provided on the inner surface of the shaft cover (9).

Next, the operation will be explained.

When cooking rice, high pressure is applied to the lid (2) and the lid (2) is
I try to push it up in the direction of the arrow in the figure, but the retaining part (9b
) is engaged with the shaft (8a), so that the shaft (8a)
This is to suppress this upward force and prevent deformation of the lid.

In the above embodiment, six lid bodies (7) are provided so as to be disposed below the shaft (8a) and engage with the shaft (8a). The same effect can be obtained even if the

〔Effect of the invention〕

As explained above, this invention has the effect of preventing deformation of the lid by engaging the end of the shaft with the lid.

FIG. 2 is an overall perspective view, FIG. 3 is a perspective view of a shaft showing another embodiment of the present invention, and FIG. 4 is an overall perspective view of a conventional rice cooker.
FIG. 5 is a perspective view of the inner surface of the lid. In the figure, (6) is the rice cooker body, (7) is the lid body,
(aa) is a shaft, and (9b) is an engaging portion. In each figure, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Claims] (1) A rice cooker main body, a lid provided on the upper side of the rice cooker main body, a length of 1/3 or more of the width of the lid provided at the rear of the lid, and a lid that is used for cooking the rice. A rice cooker comprising: a shaft rotatably supported on a main body; and an engaging portion for engaging an end of the shaft with the lid.
