The food is lined up and the food is baked by the heat generated from the heat source below. The heat source that can be used for the seven wheels is limited to solid fuel charcoal, but the tabletop furnace has a gas burner or electric heater as a heat source and can use gas or electricity, which is highly convenient.

題を有している。However, in the conventional furnace as described above, the box-shaped main body is formed of the metal plate, and therefore, when the heat source in the main body emits heat, the side surface of the main body heated by the heat source. There is considerable heat dissipation from the bottom
Due to the heat radiation, there is a problem that the surface of the table on which the furnace is placed is heated and deteriorated, and the side surface may be burned when a part of the body touches it.

ある。Therefore, an object of the present invention is to prevent the surface of a table or the like on which it is placed from deteriorating due to heat radiation from the bottom surface, or even when a person touches the side surface.
(EN) It is possible to provide a tabletop furnace in which the temperature rise of the surface (side surface and bottom surface) of the main body is suppressed so as not to be burned.

る構成のものとしたのである。In order to solve the above-mentioned problems, in the tabletop furnace according to the present invention, the heat source is mounted at a predetermined distance between the side surface and the bottom surface of the main body, and the side surface thereof is mounted. And two metal plates are arranged to face each other in the thickness direction, and a heat insulating material layer is formed on both of the two metal plates, or at least on the facing surfaces of the metal plates on the side closer to the heat source. In addition, since it has a multi-layer structure in which an air layer is provided between the facing surfaces, and a ventilation hole that connects the air layer and the outside of the main body is formed on the side surface and the bottom surface, is there.

たものとなる。In such a tabletop furnace, most of the heat generated from the heat source is above the opening of the main body through the distance space provided between the heat source and the side surface and bottom surface of the main body. The remaining heat is dissipated to the side surface and the bottom surface, and the heat transferred to the side surface and the bottom surface is also a heat insulating material formed on the opposite surface of the metal plate near the heat source inside the side surface and the bottom surface. The layer suppresses the outward movement and moves upward, and nevertheless, the heat that has moved to the air layer is radiated to the outside through the ventilation hole that communicates with the outside of the main body, so that the outside of the side surface and the bottom surface are finally exposed. The heat transmitted to the metal plate on the side (the metal plate away from the heat source) becomes extremely small, and the temperature rise on the side surface and the bottom surface of the main body is remarkably suppressed.

のとなる。At this time, if a heat insulating material layer is formed also on the opposite surface of the metal plate on the outer side of the side surface (or on the lower side of the bottom surface), the heat of the air layer is further outside (lower surface) by the heat insulating material layer. Since the amount transmitted to the metal plate (side) is suppressed and goes to the ventilation hole, the temperature rise on the surface of the main body is further suppressed.

Since the air can be forcibly convected to prevent the heat from staying, the temperature rise of the bottom surface can be further suppressed.

In the case, by connecting a pipe for injecting and extracting a refrigerant that communicates with the outside of the main body, to those closed tanks or pipes, the refrigerant can be injected from the outside of the main body, and the refrigerant can be circulated.
The refrigerant can absorb the heat radiation from the heat source to the bottom surface and further suppress the temperature rise of the bottom surface.
