본 발명은 기존의 전자렌지에 마이크로파 조사에 의하여 적외선을 방출할 수 있는 적외선 방출 소자를 전자렌지 내부에 설치함으로써 적외선 가열 기능을 부가 하여 기존의 가스 오븐이나 전기 오븐에서와 같이 적외선에 의한 조리 기능을 전자렌지에서도 갖도록 한 것이다.According to the present invention, an infrared heating element is installed inside a microwave oven to emit infrared light by microwave irradiation in an existing microwave oven, thereby adding an infrared heating function to provide a cooking function by infrared rays as in a conventional gas oven or an electric oven. It is to have a microwave oven.

이는 마이크로파가 조사되는 챔버 내부의 상부와 측면에 마이크로파에 의해 적외선이 방출되는 탄소봉 또는 석영관에 활성탄을 채워 밀봉한 관을 설치하고, 타원형 반사경을 부착하여 챔버 공간 중심부에 적외선이 집중되도록 하고, 적외선 방출봉 앞쪽에는 개폐판을 부착하여 방출봉으로부터 방출되는 적외선을 차단 또는 방출할 수 있도록하여 적외선 양의 조절 기능을 갖도록 구성되며 이러한 구성을 갖게 함으로서 가스오븐 또는 전기오븐의 조리기능을 전자렌지에서도 달성할 수 있게 한 것이다.It installs a sealed tube filled with activated carbon in a carbon rod or quartz tube where infrared radiation is emitted by microwaves on the inside and the side of the chamber where microwaves are irradiated, and attaches an elliptical reflector so that infrared rays are concentrated in the center of the chamber space. The opening and closing plate is attached to the front of the discharge rod to block or emit the infrared rays emitted from the discharge rod and to control the amount of infrared rays. By having such a configuration, the cooking function of the gas oven or the electric oven can be achieved in the microwave oven. It was made possible.

종래의 전자렌지는 음식물을 끓이거나 덥히는 역할만 할 뿐 굽는 역할을 할 수 없었고, 가스오븐이나 전기오븐은 굽는 역할만 할 수 있을 뿐 끓이거나 덥히는 역할을 하기에는 적합하지 못한 것이 문제였다.Conventional microwave ovens could only serve to boil or warm food, but could not serve to bake, and gas ovens or electric ovens could only serve to bake, but were not suitable to serve to boil or warm.

따라서 이와 같은 문제점을 해결하고자 시도된 것이 전기히터를 전자렌지 상부에 설치하거나 또는 할로겐 등에서 방출되는 빛을 조리 음식물에 조사하는 방법 등이 있으나 이 역시 모두가 음식을 굽는 역할의 기능을 원활하게 수행하지 못하는 문제점이 있다.
Therefore, there have been attempts to solve such problems, such as installing an electric heater on the top of a microwave oven or irradiating cooked foods with light emitted from halogen, but not all of them smoothly perform the function of baking food. There is a problem.

본 발명은 위에서 언급한 문제점을 해결하기 위하여 전자렌지 또는 마이크로파 오븐 내의 천장 면과 벽면에 마이크로파 조사에 의해 적외선이 방출되는 소자를 여러개 부착하여 마이크로파 가열과 적외선 가열이 동시에 일어날 수 있게 한 전자렌지 또는 마이크로파 오븐을 발명한 것인데, 이를 첨부 된 도면과 함께 더욱 상세히 설명하면 다음과 같다.
In order to solve the above-mentioned problems, the present invention provides a microwave oven or a microwave oven in which microwave heating and infrared heating are simultaneously performed by attaching a plurality of devices emitting infrared rays by microwave irradiation to the ceiling and wall surfaces of the microwave oven or microwave oven. Invented the oven, which will be described in more detail together with the accompanying drawings.

The present invention is to install a plurality of infrared emitting rods (1) on the top and the wall in the microwave chamber (A), more specifically, the carbon rod or quartz tube filled with activated carbon on the top and the wall in the microwave chamber (A), then the quartz tube Install several infrared emitters (1) formed by sealing both ends, and make an infrared emitter (1) and an elliptical metal reflector (102) or a planar reflector (12) in the middle of the wall to the length of the infrared emitter (1). Longitudinally attached to the wall surface, and in front of the infrared emitting rod (1) is equipped with infrared opening and closing plates (103, 104) made to block or discharge the infrared rays emitted from the infrared emitting rod (1) to each infrared emitting element , The wall surface in the remaining chamber (A) is composed of a metal plate that is easily reflected by infrared rays, and fine holes (usually a hole diameter Ø of 3m / m in the opening / closing door viewing window 13 of the cooking food inlet and outlet) The thin-film metal screen (using aluminum thin film, etc.), which has a large number of holes D between holes (about 5 m / m), is blackened on one side so that this colored portion faces outwards. ) Is attached to the opening / closing door see-through window 13 to prevent infrared rays from being emitted out of the chamber A through the see-through window so as to increase the density of the infrared rays in the chamber A, thereby constructing a microwave oven or microwave oven to have an infrared emission function.

At this time, the electric field directions emitted from the waveguides are installed perpendicular to each other so that interference between adjacent chambers does not occur. (If the waveguide 3 emission field direction of the first chamber is parallel to the conveyor belt 8 traveling direction, the waveguide tube 3 emission field direction of the second chamber is perpendicular to the conveyor belt 8 traveling direction. A plurality of infrared ray emitting rods 1 may be provided between the chamber A and the adjacent chamber A to construct a microwave oven or oven of large capacity.

이와 같이된 본 발명은 기존 전자렌지의 신속한 조리 및 데우기의 특성과 가스오븐이나 전기오븐의 굽는 특성을 동시에 갖게 함으로서 기존 전자렌지 또는 마이크로파 오븐의 기능을 향상시키게되고 이로인해 조리 방법을 더욱 광범위하게 실행할 수 있는 효과를 얻을 수 있을 뿐만 아니라 활성탄에서 발생되는 적외선으로 조리하므로 이것은 숯불에서 발생되는 것과 같은 파장의 적외선이므로 조리의 특성도 숯불조리시의 특성과 같은 것이 특징이다.
Thus, the present invention improves the function of the existing microwave oven or microwave oven by simultaneously having the characteristics of rapid cooking and warming of the existing microwave oven and the baking characteristic of the gas oven or the electric oven, thereby executing the cooking method more widely. Not only can the effect be obtained, but also cooked with infrared rays generated from activated carbon, so this is the same wavelength as that generated from charcoal, so the characteristics of cooking are also the same as the characteristics of cooking charcoal.
