Description

Microwave {MICROWAVE OVEN}

The present invention relates to a microwave oven, and more particularly to a microwave oven to perform cooking using a high frequency.

Various kinds of apparatuses have been proposed to date as heating apparatuses for heating foods. The most basic heating device is a container that is in direct contact with the heat source, the contents to be cooked in such a container can be cooked by applying heat to heat.

In addition, many types of cooking apparatuses that use electric energy directly or indirectly have been developed. As an example, a microwave oven using microwaves as a heating source may be mentioned. A microwave oven is a cooking apparatus that generates microwaves using electricity to infiltrate a cooking object and heats the cooking object by causing molecular motion therein.

A common microwave oven is a kitchen appliance that heats the inside and outside of the microwave by irradiating the high frequency of the magnetron to the food at the same time, significantly reducing the cooking time of the food due to high thermal efficiency, and losing the nutritional value during cooking, thawing and warming of the food. It is also widely used because of the advantages such as cooking directly while the food is stored in the container.
