Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cooking device using a far-infrared heater for baking various foods.

[Conventional technology]

Animal foods such as fish and meat, as well as plant foods such as sweet potatoes, chestnuts, and corn, usually have to be cooked over fire to make them edible. Usually caused by a red-hot heat source.

[Problem that the invention attempts to solve]

However, it took a long time for the fire to reach the inside and give the surface a dark brown color. Moreover, the degree of undercooking was determined by the cook's intuition.

In view of the above circumstances, the present invention aims to provide a far-infrared cooking device using a far-infrared heater.

[Means for solving problems]

The configuration of this far-infrared cooking device is such that heat sources are placed in the upper and lower parts of the cooking chamber space, and the object to be heated is placed between the upper and lower heat sources to heat the object from above and below.
The upper heat source is a plate-shaped far-infrared heater, the lower heat source is a rod-shaped far-infrared heater, a reflector is provided below the lower heat source, and a heat-resistant glass cover with a convex curved surface is provided above the lower heat source. Features.

[Effect]

The upper and lower far infrared heaters uniformly heat and bake the object from above and below to the inside using far infrared rays at the same time. The plate-shaped far-infrared heater on the top has a wide radiation area, so it is possible to lower the temperature of the radiation surface to obtain the specified amount of heat, and as a result, it is possible to make the far-infrared rays have a long wavelength, and the far-infrared rays can be used for food. Well absorbed and efficient. Furthermore, the radiation surface of the plate-shaped far-infrared heater is not so low that oil smoke or the like condenses, so it is not easily contaminated by oil smoke or the like. In addition, the heat-resistant glass cover that covers the top of the rod-shaped far-infrared heater at the bottom prevents the juice-like liquid generated from food from directly hitting the heater, and any oil that drips onto this cover flows down along the convex curved surface. Therefore, heat-resistant glass covers are less likely to be contaminated.
