Exothermic enamel glaze, and exothermic container coated with same

Abstract

The invention relates to a heating container used in a microwave oven using a magnetron to cook food. The heating container absorbs a part of the high-frequency wave generated by the magnetron and generates heat, and uses the high-frequency wave to cook the food in the cooking room of the microwave oven. In the present invention, the exothermic enamel glaze is produced, and the above-mentioned manufactured exothermic enamel glaze is coated on a container made of metal material for enamel (steel plate for low-carbon enamel, aluminum, stainless steel), dried, and then vitrified and fired. , cooling, and produce a heating enamel container for microwave ovens. Therefore, compared with existing heating container products (silicone rubber + ferrite), it can withstand high temperatures, has higher heating performance, and can achieve high-grade. The method for manufacturing the heat-generating enamel glaze is characterized in that, in the glaze (vitreous Frit) commonly used in enamel treatment, ferrites with high magnetic permeability (MnZn class, MgCuZn class, NiZn class, etc.) are added separately or mixed. type) and metal soft magnetic material (Fe-Si type, Fe-Si-Al type, Fe-Si-B type, Fe-Si-B-Co type, Fe-Ni type) alloy powder to produce A heat-generating enamel glaze that absorbs microwaves (2.45GHz) in a microwave oven and converts them into heat energy.

Description

technical field [0001] The invention relates to a heating container used in a microwave oven for cooking food with high-frequency vibration emitted by a magnetron and a heating enamel glaze coated on the surface thereof, especially relates to absorbing The heat-generating substance that generates electromagnetic waves is mixed with enamel glaze, so it has heat resistance that can withstand higher temperatures and improved heat-generating characteristics than conventional products. This is a heat-generating container for microwave ovens. Background technique [0002] Normally, a microwave oven is an appliance that emits 2.45GHz high-frequency waves emitted by a magnetron into the cooking room, and cooks food by vibrating the molecular arrangement of food. [0003] Among the recent compound microwave ovens, there is an increasing trend of microwave ovens that are equipped with heating wires inside the microwave cooking chamber and function as conventional electric ovens.

Problems solved by technology

However, it uses glass and ceramic materials that pass through electromagnetic waves, so there is a high possibility of damage during handling, and there is a disadvantage of heavy weight when the container is large.

[0010] As mentioned above, the realization methods of heating containers for microwave ovens used so far have disadvantages such as operating temperature, handling convenience, unit manufacturing components, etc., and in particular, there is a problem in processing that it is difficult to handle complex shapes.
