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 served as human skin temperature.

If the temperature of the sushi rice is too high and it is useless, and if it is cooled, especially if the temperature is below 8 degrees and the starch quality is beta, it is not suitable for nigiri sushi and the temperature control 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 insulating effect, plastic heat insulating containers have been used in recent years.

This plastic heat insulation container is easy to process. As shown in FIGS. 6 and 7, a heat insulation container main body 60 having an open top and an opening / closing lid 61 for closing the opening are provided. A hollow portion 60a for heat insulation is formed on the bottom plate and the side wall of the main body 60. With such a structure, it is possible to prevent the sushi rice at the human skin temperature stored in the heat insulation container body 60 from being cooled to some extent by heat conduction with the container. Then, a required amount of shari is picked up from the heat insulation container main body 60 to make a shari ball for nigiri 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 this plastic heat insulation container is used, the rice cooked on the previous day cannot be used for nigiri sushi.

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 the steam generated by the heat accumulates, and the quality of the rice cake deteriorates, which is not suitable for keeping the temperature of humidity and temperature of sushi rice difficult. .

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

On the other hand, when the above-mentioned heat insulating container is used in a kitchen, the heat insulating container is conventionally placed on a work table or the like, but the work table itself has a height suitable for work. However, when the heat insulating container is placed on the heat insulating container, the position of the heat insulating container is too high for removing and replenishing the rice from the heat insulating container, and there is a problem that the work is difficult.

The present invention solves the above-mentioned problems in the conventional shari warming device and its use, and the shari warming device can keep the stored shari at an appropriate temperature for a long time without drying. Another object of the present invention is to provide an easy-to-use kitchen device equipped with a rice warming device.

According to another aspect of the present invention, there is provided a warm heat retaining device comprising a heat retaining device main body having a heating means, a heat retaining container made of a plastic material, which is housed in the heat retaining device body so as to be drawn out and has a heat retaining hollow portion on a peripheral wall thereof. It is characterized by having and.

According to the apparatus for keeping warm of the rice of the present invention, by heating the plastic heat-retaining container having the heat-retaining hollow portion on the peripheral wall, the temperature can be kept on human skin without drying the rice in the container. That is, the heating means provided in the heat retaining device main body first heats the air between the inner surface of the heat retaining device main body and the outer surface of the plastic heat retaining container, and by the heated air, the side surface of the plastic heat retaining container and The bottom surface is warmed, and the outer wall heat of the further warmed plastic heat insulation container is absorbed 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 serves as a heat source for keeping heat without generating steam.

By storing the plastic heat insulation container in the heat insulation device body so that it can be drawn out, the plastic heat insulation container can be pulled out from the heat insulation device body to a position where it can be easily used, and the usability is improved.

Further, the kitchen device of the present invention is a kitchen device in which a part of the top plate of the cooking counter is formed one step lower, and the rice warming device is placed on the one step lower part. Further, the cooking counter and the storage cabinet are arranged so as to face each other, a part of the top plate of the cooking counter or the storage cabinet is formed to be one step lower, and the kitchen device in which the rice warming device is placed on this one step lower part You can also
