Description

[Detailed explanation of the invention] This invention is for kamameshi, in which about 5 to 1 cup of rice is placed in a small pot along with oysters, shellfish, shrimp, chicken, wild vegetables, etc., and seasoned with soy sauce, sake, etc. It is related to rice cookers.

The present applicant previously provided a device suitable for cooking a small amount of rice in the Japanese Utility Model Publication No. 3642/1983.

As a result, rice can be cooked in 8 to 2 minutes without burning using a strong direct flame of a gas burner, compared to the conventional cooking time of 2 to 2 minutes. It has become possible to efficiently prepare kama-meshi for commercial use, which involves cooking a large number of kama-meshi at a time.

On the other hand, in order to cook kama-meshi in a small pot in a short time of 8000 ml, it is necessary to directly heat the rice all at once over high-calorie high heat.

As a result, the inner pot, which is housed in the outer pot, rises due to the sudden heating pressure during rice cooking, and heat convection is not evenly carried out.
This was causing noise.

Therefore, the present invention is based on the above-mentioned Utility Model Publication No. 56-3642 of the present applicant.
The structure of the boiler according to the invention of No. 21- is further improved, and the object is to improve the stability of the inner pot during rice cooking, thereby making it possible to cook rice better in a short time.

In order to achieve the above-mentioned purpose, the present invention has been developed to
An inner pot 3 formed so as to be in contact with the inner surface of the pot is housed in the outer pot, and the height h of the inner pot 3 is set lower than the depth d of the outer pot, and the inner pot opening edge 32 An inner pot holding member 4 is detachably attached to the inner surface 11 of the outer pot located directly above the pot, and a metal lid 2 provided with a pressure regulating valve 5 is placed over the opening 12 of the outer pot.

In addition to those in which the inner surface 11 has a smooth curved surface as in the first and second outer pots, there is also one in which a circumferential terrace portion 6 is formed in the middle part of the inner surface of the outer pot, as shown in the chain diagram in FIG.

The metal lid 2 can be made of cast iron, and its weight is 600 to 700 g for the rice cooking capacity of 5 to 1 cup of the small capacity outer pot 1 shown in the figure.
The degree is appropriate.

The handle 22 of the metal lid is made of wood and is fixed with screws n.

In addition, the pressure regulating valve 5 on the metal lid has a small hole in the case shown in the figure, and the hole diameter is set in relation to the capacity of the outer pot, but is 0.7 to 1.
．． Five cabinet positions is appropriate.

Next, the inner pot 3 may be made of a rust-proof metal such as a thin aluminum plate, aluminum foil, or stainless steel plate, and its height h is set lower than the depth d of the outer pot 1.

A small hole 7 is made in the bottom of the inner pot 3.

The number of small holes is arbitrary, such as single or plural, but in the case of a single hole, the diameter is 3 to 6rrrtn as shown by the chain line in FIG.
Relatively large small holes 71 at the front and rear shall be made in the center of the bottom surface.

In addition, in the case of a plurality of diameters, as shown by the solid line in Figs.
It is best to open a small diameter around 0 to 2.0 figures.

The inner pot holding member 4 is fitted into the inner surface 11 of the outer pot at a position directly above the inner pot 3, that is, in contact with the opening edge of the inner pot, and its shape is made of steel such as stainless steel as shown in FIGS. A plastic band or a heat-resistant plastic band is formed into an annular shape to form an elastic ring that has a circular plane and expands outward, and a clamping device or fingers are placed near both ends of the elastic ring. A clamping portion 8 is provided through which the diameter can be reduced and taken out.

Further, a water draining recess 9 is formed at the lower end of the holding member.

The shape of the holding portion 8 is shown in FIGS. 2 and 5.
In addition to those with protrusions as shown in Fig. 6, there are also those with recesses such as holes as shown in Fig. 7.

Since the present invention has the above-mentioned configuration, when rice is cooked by directly heating the outer pot with the high heat of a high-calorie gas burner, the inner pot holding member 4 prevents the inner pot 3 from rising due to the heating force. This can be reliably prevented, and furthermore, the rattling noise that accompanies the floating action can also be prevented.

Further, the holding member 4 is made of an elastic ring body having an expanding action as shown in FIG. can be stored or taken out easily and reliably.

Furthermore, even if the inner surface of the outer pot is a smooth curved surface, the inner pot 3 is reliably held by the restraining force of the ring-shaped holding member 4.

Since the water draining recess 9 is provided at the lower end of the holding member, when water in the pot blows up during rice cooking, it flows through the recess and heat convection occurs smoothly, further improving rice cooking efficiency. do.

In addition, the metal lid 2 has a weight commensurate with the capacity inside the pot and the pressure regulating valve 5, so that the pressure inside the pot can be maintained appropriately during rice cooking.

Furthermore, the small hole 7 provided in the bottom of the inner pot 3 prevents the rice from burning even when cooked for a short time using a powerful direct flame, and delicious rice that takes advantage of the unique flavor of rice is cooked.
