Description

[Detailed description of the invention] The purpose of the invention is to prevent rice cookers from being overflowing.

Conventionally, when cooking rice in a rice cooker, if you added more water than a certain amount to the amount of rice, bubbles called "Oneba", a mixture of starch and water, would sometimes come out.

This phenomenon has been observed in elderly people or when cooking extremely soft rice depending on the region.

Therefore, various countermeasures have been devised.

For example, a complicated passage barrier was installed inside the steam vent through which steam exits the rice cooker, and the passage resistance was used to collapse the bubbles in the rice cooker.

Among these various proposals, one that was particularly effective was to increase the distance between the steam cylinder, which is the steam exhaust port, and the steam passage hole provided in the inner lid.

The reason for this is that the bubbles collapse on the way due to the long distance.

However, in order to always maintain a certain distance between the steam passage hole and the steam cylinder, it was necessary to create a passage barrier along the way or to regulate the position of the inner lid.

In order to regulate this position, a part of the inner cover needs to have a shape that fits with the steam cylinder or other parts, and when cooking rice in the rice cooker, the inner cover is attached to match this fitting part. Therefore, it is not easy to use, and if the fitting method is incorrectly attached, the inner cover may be deformed, which is inconvenient, and the number of parts increases.

The present invention solves the above-mentioned conventional drawbacks, and embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a main body, and this main body 1 is equipped with a pot 2 that is detachable.

3 is an inner lid that covers the upper opening of the pot 2, and 4 is an outer lid that covers the inner lid.

A steam cylinder 5 is eccentrically provided on the outer lid 4.

Further, a holder 6 projects eccentrically from the lower surface of the outer lid 4 toward the steam cylinder 5 side.

A holder hole 7 is formed in the center of the inner lid 3, and a holder hole 7 is formed in the center of the inner lid 3.
A holder hole 7 is attached to the holder via a backing 8.

A flat part 10 is formed on the outer periphery of the inner lid and is in surface contact with the flange 9 at the upper end of the pot 2, and this flat part 10 is provided with a plurality of through holes 11 over the entire circumference.

In the above configuration, when the pot 2 is covered with the inner cover 3 and the outer cover 4, the inner cover 3 is eccentric toward the steam cylinder 5 side with respect to the pot 2 because the holder 6 is eccentric.

In this state, among the through holes 11 provided in the flat surface part 10 on the outer periphery of the inner lid 3, the through holes 11 on the steam cylinder 5 side are connected to the flange 9.
The through hole 11 on the opposite side of the steam cylinder 5 faces the inside of the pot 2 and is in an open state.

Therefore, when rice is cooked and bubbles are generated, they pass through the through hole 11 on the opposite side of the steam cylinder 5, pass over the inner M3, and reach the steam cylinder 5.

The distance from the open through hole 11 to the steam cylinder 5 is long,
The bubbles will collapse and will not gush outside.

In addition, since the inner M3 is symmetrical, the holder 6 of the outer cover 4
There is no need to consider the direction when installing the device, making it easier to handle.

As is clear from the above explanation, according to the present invention, it is possible to prevent the discharge of bubbles without providing an obstacle wall on the inner lid, and the structure is simple, and there is no need to consider the direction when using it, making it easy to use. Its practical value is great, such as its good performance.
