Abstract

본 발명은 전자레인지의 스팀발생장치에 관한 것으로, 종래에서는 히터로 물을 가열하여 스팀을 발생시키기때문에 전력소비가 많고 스팀발생을 위한 히터를 따로 설치해야 하므로 제품가격이 상승하는 문제점이 있었다.The present invention relates to a steam generating apparatus of a microwave oven, and in the related art, since water is generated by heating water with a heater, power consumption is high and a heater for generating steam has to be installed separately, thereby increasing the product price.

본 발명은 이와같은 종래의 문제점을 해결하기 위하여 스팀발생을 위한 가열장치를 따로 사용하지 않고, 마그네트론 방진시 발생되는 열을 이용하여 스팀을 발생시키며 냉각팬을 제어하여 마그네트론의 온도를 제어할 수 있으므로, 냉각팬을 걔속 온시키지 않고 마그네트론의 온도가 설정치에 도달하면 온시켜 냉각팬 구동에 의한 전력소모를 줄일 수 있다.In order to solve the conventional problems, the present invention does not use a heating device for steam generation separately, and generates steam using heat generated when the magnetron is dustproof, and thus the temperature of the magnetron can be controlled by controlling a cooling fan. Therefore, it is possible to reduce power consumption by driving the cooling fan by turning it on when the temperature of the magnetron reaches the set value without turning on the cooling fan.

또한, 요리시 고주파에 의해 음식물에 포함된 수분이 증발하여 본래의 음식맛을 잃게하는 문제점을 해결하게 된다.In addition, the moisture contained in the food by the high frequency when cooking to solve the problem of losing the original food taste.
