[Function] When the heating body 2 is heated to a high temperature by the heat source installed in the stove 1 and the cooker is placed on the heating body 2, the conduction heat and the radiant heat from the heating body 2 and the heating body 2 are touched. It can be boiled and cooked by the heat of the air that has reached a high temperature.

According to the present invention, the above heating-type stove is provided with a cooling device composed of a blower 3, a blowing passage 4, a blowing nozzle 5, a heat shield plate 6 and a heat shield guard 7. When the plate 6 and the heat shield guard 7 are pivotally positioned on the heating body 2 of the stove 1, the heat generated from the heating body 2 of the stove 1 becomes radiant heat and heats the heat shield plate 6, but blows out. The heat shield plate 6 is cooled by the cool air of the blower 4 blown out from the nozzle 5.

The heat shield 7 is heated by the radiant heat emitted from the heat shield plate 6, but the radiant heat is much smaller than the amount of heat emitted from the heating body 2, and further the air sent from the blower 4 causes the heat shield 7 to move. Was cooled at the same time, and the heat shield 7 was kept at a low temperature after all, so that the upper space of the heat shield 7 can be used for various purposes immediately after boiling.

Further, the blower 4 of the cooling device is turned on and off by the signal of the heat sensitive element 9 mounted in the main body of the stove 1, and the blower 4 rotates when the temperature of the heating body 2 rises.
Therefore, if the heat shield guard 7 is lowered on the heating element 2, the cooling air is blown to the heating element 2, so that the cooling effect is immediately obtained, and when the stove 1 is cooled, the blower 4 is automatically stopped. Is.

Further, the cooling device is detachably attached to various stoves. Even if the stove has already been installed, the cooling device can be attached if necessary, and the range of use conditions is widened. It is a thing.
