본 고안은 전자렌지의 감압형 고주파 가열실(이하 가열실이라한다)를 밀폐하고 감압한 후 피 가열물을 고주파로 조사(照射)하여 강력한 건조를 행하게하는 감압 고주파건조장치에 관한 것이다. 전자렌지의 가열실을 감압상태에서 고주파로 조사할 경우 피 가열물로 부터 증발된 수분으로 인해 자계(磁界)강도가 높은 고주파 에너지 공급구(供給口)부근에는 글로우 방전(Glow 放電)현상이 발생함과 동시에 진공밀폐창에 물방울이 부착케되고 고주파의 일부는 이 물방울에 반사되어 가열실내에의 고주파 에너지공급이 감소되는 사례가 있음은 이미 알려진 바이나 이 현장을 방지하기 위하여 종래에는 마그네트론 냉각용 송풍기의 배개열(排氣熱)을 진공 밀폐창에 접촉시킴으로써 수분을 증발케하는 방식이 외국에서는 채택되고 있다.The present invention relates to a reduced-pressure high-frequency drying apparatus for sealing a pressure-sensitive high-frequency heating chamber (hereinafter referred to as a heating chamber) of a microwave oven and then performing a strong drying by irradiating the heating target with high frequency. When the microwave heating chamber is irradiated at high frequency under reduced pressure, a glow discharge phenomenon occurs near the high frequency energy supply port with high magnetic field intensity due to the water evaporated from the heated object. At the same time, it is known that water droplets adhere to the vacuum-sealed window and some of the high frequency waves are reflected by the water droplets, thereby reducing the high-frequency energy supply to the heating chamber. In foreign countries, a method of evaporating moisture by contacting the exhaust heat of a blower with a vacuum sealed window is adopted.

그러나 첫째 진공밀폐창으로 사용되고 있는 물질자체가 연전도율이 낮은 합성수지 제품이며 그 두께도 상당한 고로 열전도에 소요되는 시간이 클 뿐 아니라 둘째 마그네트론의 온도는 동작후 상당시간 가동후라야 상승됨으로 송풍기의 배기열 온도상승 역시 상당시간이 걸리게 된다.First, however, the material used as the vacuum sealing window itself is a synthetic resin product with low electric conductivity, and its thickness is also high for the blast furnace heat conduction. Second, the temperature of the magnetron is raised only after operating for a long time. The rise will also take considerable time.

이에 반하여 가열실내의 피 가열물로 부터의 수분 발산은 마그네트론의 동작과 동시에 발생함으로 최조 상당시간은 글로우방전 현상의 발생을 방지할 수 없는 결점이 있는 것이다.On the contrary, the moisture dissipation from the heated object in the heating chamber is generated at the same time as the operation of the magnetron.

본 고안은 이러한 결점을 시정하기 위해 안출한 것으로써 진공밀폐창의 가열실을 향한면에 고주파 에너지의 조사로 온도 상승이 가능한 합성수지 고무(이하 고무라 한다)를 도포(塗布)함으로써 마그네트론의 동작과 동시에 고무의 온도를 상승케하여 피 가열물로 부터의 수분의 비산과 진공밀폐창에 부착된 수분을 즉시 증발시켜 글로우 방전을 사정에 예방하는 효과가 있는 것이다.The present invention was devised to rectify these defects, and by applying synthetic resin rubber (hereinafter referred to as rubber) that can rise in temperature by irradiation of high frequency energy on the surface facing the heating chamber of the vacuum-sealed window, the rubber and the rubber at the same time It is effective to prevent the glow discharge by raising the temperature of the water and immediately evaporating the moisture from the heated material and the moisture attached to the vacuum sealed window.

본 고안의 구조를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The structure of the present invention will be described in detail with reference to the accompanying drawings.

안테나(3)을 포함한 마그네트론등 전기부품으로 구성된 고주파 에너지 발생장치(2)로부터 발생한 고주파 에너지는 도파관(4)와 고주파 에너지 공급구(5)로 유도되고 진공밀폐창(6)을 거쳐 가열실(1)에 공급되도록 되어있다. 진공펌프(8)은 가열실(1)의 외부에 연결된 배기관(7)에 부착되었으며, 감압증 외부공기가 가열실(1)에의 진입을 차단 또는 건조 후 외부 공기의 주입등을 위해 콕크(10)을 배기관(7)과는 별도 방향의 관에 부설하고 배기팬(9)는 대기압하에서 고주파 조리 또는 히-타(12)와 병용하는 오븐 조리시에 배기를 위한 것이다.The high frequency energy generated from the high frequency energy generator 2 composed of electrical components such as a magnetron including the antenna 3 is guided to the waveguide 4 and the high frequency energy supply port 5 and passed through the vacuum sealing window 6 to the heating chamber ( It is to be supplied to 1). The vacuum pump (8) is attached to the exhaust pipe (7) connected to the outside of the heating chamber (1), and the cock (10) for the injection of external air after blocking or drying the decompression external air into the heating chamber (1). ) Is placed in a pipe in a direction separate from the exhaust pipe 7, and the exhaust fan 9 is for exhausting air at the time of cooking under high pressure or oven cooking in combination with the heater 12.

상기와 같은 구조와 구성을 갖은 본 고안의 주요 동작과 그 기능을 설명하면 다음과 같다.The main operations and functions of the present invention having the structure and configuration as described above are as follows.

가열실(1)은 진공펌푸(8)의 구동으로 감압되어 가열실(1)에 수용된 피 가열물(1)의 불등점(佛騰点)을 계속 강하케하며 통상 대기압에서 보다 훨씬 저온상태에서 급속한 건조가 진행된다. 이로 인해 피 가열물(11)의 표면으로 부터는 급격한 수분의 증발과 분출이 발생하여 진공밀폐창(6)에는 물방울이 부착하게되나 한편 마그네트론의 가동과 동시에 진공밀폐창(6)의 저면에 도포된 도시하지 않은 고무는 가열 되어 고온이 됨으로 부착된 수분은 즉시 증발, 제거된다.The heating chamber 1 is depressurized by the operation of the vacuum pump 8 to continuously lower the inequality of the heating object 1 accommodated in the heating chamber 1 and is usually at a much lower temperature than at atmospheric pressure. Rapid drying proceeds. This causes rapid evaporation and ejection of moisture from the surface of the object to be heated 11, which causes water droplets to adhere to the vacuum sealing window 6, while simultaneously applying the magnetron to the bottom surface of the vacuum sealing window 6 The rubber not shown is heated to a high temperature so that the attached moisture is immediately evaporated and removed.

또한(13)은 가열실(1)을 밀폐키 위한 고무로된 밀폐 팍킹이고(14)는 진공밀폐창(6)과 밀폐 팍킹(13)을 내장하도록 형성된 후렌지로서 도파관(4)와 가열실(1)을 연결한다.In addition, 13 is a rubber sealed packing for sealing the heating chamber 1, 14 is a flange formed so as to incorporate the vacuum sealing window 6 and the sealed packing 13, the waveguide 4 and the heating chamber ( Connect 1).

이상과 같이 구성된 본 공안은 감압하에서의 고주파 가열시 심하게 발생하는 피 가열물(11)로 부터의 수분증발과 분출로 인해 진공 밀폐창(6) 저면에 부착된 물방울을 마그네트론 가동과 동시에 가열된 도시하지 않은 고무 표면의 고온으로 이를 즉시 증발, 제거케함으로써 고주파 에너지 공급구(5)부근에 글로우 방전의 발생은 물론 물방울에 고주파의 일부가 반사됨으로써 가열실(1)에의 고주파 에너지 공급을 감소하는 결합을 극소화하는 효과가 있는 것이다.The present invention constructed as described above does not show that water droplets attached to the bottom of the vacuum sealing window 6 are heated simultaneously with the operation of the magnetron due to the evaporation and ejection of water from the heated material 11 that is severely generated during high frequency heating under reduced pressure. By immediately evaporating and removing the high temperature of the rubber surface, the glow discharge is generated near the high frequency energy supply port 5 as well as a part of the high frequency is reflected by the water droplets to reduce the high frequency energy supply to the heating chamber 1. It is effective to minimize.
