Description

The present invention relates to an improvement in an apparatus for heating and cooking food such as chicken, fish, and vegetables by efficiently irradiating far infrared rays from the surroundings.

Far-infrared heating has become popular since the Showa 40's, mainly starting with paint drying related to the automobile industry, and since heat treatment is performed in a short time, the productivity is reduced and the length of the heating furnace is shortened. The technology began to be widely used in the industry. At present, it has been widely adopted as a division of the heat treatment process.

On the other hand, as a method of heating food, if the food is baked directly with the high-temperature combustion gas of the gas burner, only the surface is easily carbonized, and the pan is heated with the combustion gas, and the food is applied to the high-temperature surface. When heated by contact, there is a drawback that it takes time until the heat is transmitted to the inside of the food. Therefore, when far infrared rays are used, they are directly absorbed by food materials in the form of electromagnetic waves, and the surface and the inside are heated in a short time. Specifically, it is a method for heating a grilled salmon or grilled chicken.

However, as seen in Patent Document 1, conventionally, as a cooking heating device, there is an open function that combines a grill function for scorching food with radiant heat and an oven function for increasing food temperature with far-infrared temperature. There has been proposed an oven in which two types of heaters are provided in the ceiling portion as a microwave oven, and a heater for heating is further provided in the lower portion. Even if several types of heaters are provided, the object to be heated is kept at the bottom, and if the size changes, the heat utilization efficiency from each heater will not be optimal. If a drip occurs, there is a disadvantage that it falls on the lower heater.

Further, as seen in Patent Document 2, there has been proposed a method of heating an object to be heated with radiant heat radiated from a wall surface made of a heat-resistant metal plate by flowing a combustion gas to the left and right walls and the ceiling. However, since the object to be heated is heated on a net provided on the lower tray, there is a drawback that a difference in heating state occurs between the upper surface and the lower surface of the object to be heated.

Therefore, the present inventor suspends an object to be heated as shown in the Internet home page of Dryup Japan Co., Ltd. and Non-Patent Document 1, and a plurality of far infrared heaters around the object. And a vertical cooking device with a metal plate that reflects the radiant heat of the heater was developed on the outside. As a typical method of use, it is sold as a device for producing shochu. However, for example, there is no problem if the apparatus is used exclusively for baking firewood of almost the same size, but if the size of the object to be heated becomes small, the distance between the heater and the object to be heated becomes long and exists between them. There is a drawback that far infrared rays are absorbed by water vapor having a polarity composed of evaporated water, and as a result, the time required for heating becomes long.
