Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warmer heat retaining device, and more particularly to a heat retaining device suitable for keeping warm sushi rice.

[0002]

2. Description of the Related Art Shari used in nigiri sushi is made by cooking plain white rice a little harder than ordinary rice, and dissolving 0.7 vinegar per 1 square of rice and 1 tablespoon of salt. Are made together. The sushi rice made is cooled with blue and used as human skin temperature.

If the temperature of sushi rice is too high, it is useless, and if it is cooled, especially if the temperature of the rice is cooled to 8 degrees or less and the starch content is converted into beta, it is discarded and the temperature is controlled. It is considered important.

Conventionally, wooden sushi tubs have been most commonly used as a method for storing such sushi rice.
Since conventional sushi tubs have no heat-retaining effect, plastic-made heat-retaining containers have recently been used.

This plastic heat insulation container is easy to process. As shown in FIGS. 5 and 6, the heat insulation container main body 50 has an open top surface and an opening / closing lid 51 for closing the opening. A hollow portion 50a for heat insulation is formed on the bottom plate and side wall of the main body 50. With such a structure, it is possible to prevent the sushi rice at the human skin temperature stored in the heat insulation container body 50 from being cooled to some extent by heat conduction with the container. A required amount of shari is picked up from the heat insulating container main body 50 to make a shari ball for hand-rolled sushi.

[0006]

However, this plastic heat insulation container merely prevents the heat of the contained sushi rice from escaping to the outside, and the heat retention time is about 3 hours at room temperature. There is no long-term heat retention effect. Therefore, even when using this plastic heat-insulating container, it is the actual situation that the rice cooked on the previous day must be discarded.

As a countermeasure against this, it is conceivable to use a heat-retaining jar used in general households. In this heat-retaining jar, the main body of the container for containing rice is heated,
The heat of this container is directly transferred to the rice as direct heat. For this reason, there is a problem that the surface of the rice cake becomes dry and hard, and steam generated by heat accumulates, which deteriorates the quality of rice cake, which is not suitable for keeping the temperature of sushi rice difficult to control humidity and temperature. .

[0008] Further, it has been attempted to inject hot water for heat retention into the heat insulating hollow portion of the plastic heat retention container described above, thereby enhancing the heat retention effect, but this is also the temperature of the inner wall of the heat retention container directly. Because it enhances
It causes the same problem as the above heat jar.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in the conventional shari warming device, and provides a shari warming device capable of holding a stored shari at an appropriate temperature for a long time without drying. With the goal.

[0010]

Means for Solving the Problems As a result of intensive studies for solving the above-mentioned problems, the present inventor has heated a plastic heat-retaining container which has been conventionally used for heat insulation, so that the plastic container is accommodated in a plastic container. The inventors have found that the temperature can be kept on human skin without drying the rice cake and have completed the present invention.

That is, the rice warming warmer according to the present invention comprises a warming warmer body having a heating means, and a plastic warming container which is detachably mounted in the warming warmer body and has a warming hollow portion on its peripheral wall. It is characterized by

As the plastic heat insulation container having a heat insulation hollow portion on its peripheral wall, a product number (SP20D) manufactured by Sekisui Chemical Co., Ltd. can be preferably used.

Also, the body of the heat retaining device is of a drawer type,
A plurality of upper and lower stages of the heat retaining device main body may be provided, and further, a transfer caster may be provided.

[0014]

The heating means provided in the body of the heat retaining device first heats the air between the inner surface of the body of the heat retaining device and the outer surface of the heat retaining container made of plastic, and the heated air causes the side surface of the heat retaining container made of plastic to be heated. And the bottom surface is warmed, and the heat of the outer wall of the warmed plastic heat-insulating container is alleviated by the hollow portion and is transferred to the inner wall surface as indirect heat. The heat of the inner wall surface is gradually transmitted to the rice cake contained in the container, and can be used as a heat source for keeping heat without generating steam.
