Abstract

PROBLEM TO BE SOLVED: To enable a warming chamber to be kept at uniform temperature to all corners using convection and circulation flow to hold the taste of Sushi rice constant by utilizing a space in between four corners of an outer box and an a Sushi rice warming jar as a blowing pipe and combining the blowing pipe, a blower, and a suction port and an exhaust port disposed on the bottom of the box. SOLUTION: The space between the outer box 1 and the Sushi rice warning jar 2 is set as narrow as possible to prevent warm wind flowing out from the box inside. Partition plates 3 are fitted on four corners of the outer box 1 to form a blowing pipe 4 and a blowing box 8 is set on the bottom part of the outer box 1 to be integrated with the blowing pipe 4. A blower 5 is set on the upper part of the blowing box 8 to generate a circulation flow and an electric heater 9 which is controlled by a temperature sensor 11 is set on the upper part of the blower 5. A jar support lattice is preferably have holes as large as possible so as not to disturb the ventilation. On the other hand, a suction hole 6 and an exhaust hole 7 are bored in the bottom part of the outer box 1 to usually suck and exhaust a small volume of air.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an economical manufacturing technique that utilizes four corners of a box as air ducts. Hot air circulation in the box by opening two holes at the bottom, and cooling assist technology.

[0002]

2. Description of the Related Art A conventional heat retaining device is an electric heater (heater).
Is a heat insulation box which is simply placed on the bottom or side of the box.

[0003]

In the conventional sushi rice preserving apparatus, the portion of the sushi rice close to the heat source (heater) becomes too hot and dries, and the portion far from the heat source does not rise in temperature.・ When making rolled sushi, the rice falls apart and is hard to harden. The taste is lost because the temperature of the whole sushi rice is not uniform.

[0004] Sushi rice is 38, as is said to be human skin.
℃ is optimal. An object of the present invention is to keep the temperature uniform throughout the heat insulation box and maintain the taste of sushi rice for a certain period of time.

[0005]

Means for Solving the Problems In order to achieve the above object, the sushi rice preserving apparatus of the present invention has a blower (fan), a blower duct (duct) and a suction hole and a discharge hole at the bottom of the box. is there.

[0006] The place where the blower tube is attached uses the four corner spaces of the outer box and the jar for keeping the sushi rice warm.

[0007] The air duct uses four corners of the outer box. By surrounding one side with a partition plate, a triangular air duct can be easily made,
Great economic effect.

Since the entire heat insulation box is substantially closed, circulation of warm air does not work properly. Therefore, one suction hole and one discharge hole are provided at the bottom of the box to promote circulation.

The above-mentioned suction hole is opened directly below the blower to take in the outside air constantly.

The other hole, that is, the discharge hole, is provided as far as possible from the suction hole so as not to suck the outside air.

The above two suction holes and discharge holes not only assist circulation but also function as a cooling device when the temperature inside the box becomes too high.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings based on embodiments.

The sushi rice warming apparatus shown in FIG. 1 is made of stainless steel because of its installation in a place where water is handled. Electric parts also use waterproof type.

In FIG. 1, the gap between the outer box 1 and the sushi rice keeping jar 2 is made as narrow as possible to prevent the hot air from flowing out of the box.

As shown in FIG. 2, the blower pipe partition plates 3 are attached to the four corners of the outer box 1 to form a blower pipe 4.

As shown in FIG. 4, a blower box 8 is also provided at the bottom of the outer box 1 to be integrated with the blower tube 4.

As shown in FIG. 4, a blower 5 is attached to the upper part of the blower box 8 so that air does not leak from the periphery.

The blower 5 uses a sushi rice warmer,
Always operate.

An electric heater 9 is mounted on the blower 5.
The electric heater 9 is controlled by a temperature sensor 11 which responds to the temperature setting.

The jar supporting grid 10 should be as large as possible with holes so as not to obstruct ventilation.

The hot air rises, does not oppose convection, and the wind direction is upward from the electric heater 9.

As shown in FIG. 5, the air flow is circulated as indicated by the arrows.

As shown in FIG. 4, the suction hole 6 is opened directly below the blower 5 so that a small amount of outside air is always taken in.

The diameters of the suction hole 6 and the discharge hole 7 are set to about 5 mm so that the heat retaining effect is not deteriorated.

The blower 5 is always operated even when the electric heater 9 is not operating, so that the residual heat of the electric heater 9 is quickly removed.

[0026]

Since the present invention is configured as described above, it has the following effects.

An economic effect by using four corners of the outer box to form a blower tube.

The uniform temperature distribution effect by changing the temperature in the box to a circulating flow instead of just a convection.

The circulation promoting effect and the cooling effect by the two holes opened in the bottom of the box.
