Description

Infrared Heating-Cook Utensil}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker using infrared rays, and more particularly, to a heating cooker using infrared rays, in which infrared rays are irradiated to a cooking plate while sequentially cooking one or more kinds of food on a stacked cooking plate, The present invention relates to a cooker.

Generally, infrared rays are not visible to the naked eye, do not scatter well in the air, and have stronger permeability than visible light rays. The infrared rays are physically divided into near infrared rays (about 0.8 um to about 2.0 um), middle infrared rays (about 2.0 um to about 4.0 um) and far infrared rays (about 4.0 um to about 1000 um) do.

Here, the infrared rays penetrate deeply into the cooking material when heating the cooking material, and have a heating effect. The infrared rays are used in heating and cooking appliances because they have stronger heat characteristics in cooking materials than visible light or ultraviolet rays.

However, the cooking utensil includes at least one cooking plate for cooking on the cooking plate, and the cooking utensil is provided with cooking utensils for baking meat or fish on the same cooking plate while fixing the irradiation direction of infrared rays or varying the irradiation direction of infrared rays along the same horizontal plane It is configured to cook.

For example, the cooking utensil has been disclosed in Korean Patent Registration No. 10-0833966 and Korean Patent Registration No. 10-1209970, which is configured to cook on a cooking plate while fixing the irradiation direction of infrared rays. And the cooking is performed on the cooking plate while varying the irradiation direction of the infrared rays along the same horizontal plane, and disclosed in Korean Registered Utility Model No. 20-0476906.

In this case, since the irradiation direction of the infrared rays is fixed or the irradiation height of the infrared rays is not varied when the irradiation range of the infrared ray is small compared to the width of the cooking plate, the temperature of the cooking plate in the central region and the peripheral region of the cooking plate Generate tea to create a poor cooking environment on the cooking plate. Therefore, the cooking utensil forms an unintentional temperature on the cooking material for each region of the cooking plate, thereby deteriorating the texture of the user.
