본 발명은 증기 발생 장치에 관한 것으로 특히 증기소독장치와 음식을 찌기 위한 장치의 증기 발생장치에 관한 것이다. 종래의 장치에서 증기를 얻기 위하여 가열 용기에 필요한 만큼의 물을 채워 가열함으로 서 증기를 얻는다. 이와 같은 종래의 방법은 채워진 물이 끓는점까지 온도가 올라가는데 많은 시간이 걸리게 되는 단점이 있다. 이와 같은 방법으로 물을 끓일 때 많은 전력을 소비하며 부피가 큰 가열용기로부터 전도나 복사로 에너지의 손실이 많이 생기는 단점이 있다. The present invention relates to a steam generator, and more particularly, to a steam sterilizer and a steam generator of a device for steaming food. Steam is obtained by filling the heating vessel with the required amount of water to obtain steam in a conventional apparatus. This conventional method has a disadvantage in that it takes a long time for the temperature to rise to the boiling point of the filled water. Boiling water in this way consumes a lot of power, and there is a disadvantage in that a lot of energy is lost by conduction or radiation from a bulky heating vessel.

본 발명에 따른 증기 발생장치는 물을 가열 판에 필요한 만큼 공급할 수 있게 되어 장치의 작동시점에서 빠르게 증기를 얻을 수 있으며 적은 전력으로 작동할 수 있게 되고 부피가 적 어서 전도나 복사로 생기는 에너지 손실이 적게 된다.The steam generator according to the present invention can supply the water to the heating plate as needed, so that the steam can be quickly obtained at the time of operation of the apparatus, can be operated with less power, and the volume is small so that the energy loss caused by conduction or radiation is reduced. Less.

이와 같은 목적의 본 발명에 따른 증기 발생 장치는 가열 판과 가온챔버를 구비한다. 가열 판과 가온챔버는 각각의 히터가 설치된다.The steam generator according to the present invention for this purpose has a heating plate and a heating chamber. The heating plate and the heating chamber are provided with respective heaters.

도 2는 본 발명에 따른 증기 발생장치의 실시 예를 전개한 것이다. 2 illustrates an embodiment of a steam generator according to the present invention.

도 1은 본 발명에 따른 증기 발생장치를 도시한 도면이다.1 is a view showing a steam generator according to the present invention.

도 4는 도 1의 A지점을 따라 취한 단면도이다. 도 2 및 4를 참조하면 증기 발생장치의 본체(2)는 가열 판(2C)에 온수 분출도관(2B) 한쪽에 고정 장착되어 있고, 다른 한쪽에 가온챔버(2A)가 고정 장착되어 있다. 본체(2)에 구성된 가열 판(2C) 상부에 본체커버(1)가 고정 장착되고, 본체 커버(1)는 증기통로인 개구부(1A)이 복수 개가 방사상으로 균등하게 형성된다. 가열 판(2C)의 하부에 가열히터(3)가 고정 장착되어 있고, 가온챔버(2A) 하부에 분출히터(4) 가 고정 장착되어 있다.4 is a cross-sectional view taken along the point A of FIG. 2 and 4, the main body 2 of the steam generator is fixed to one side of the hot water jet conduit 2B on the heating plate 2C, and the heating chamber 2A is fixed to the other side. The main body cover 1 is fixedly mounted on the heating plate 2C formed in the main body 2, and the main body cover 1 has a plurality of openings 1A, which are vapor passages, radially equally formed. The heating heater 3 is fixedly attached to the lower part of the heating plate 2C, and the blowing heater 4 is fixedly attached to the lower part of the heating chamber 2A.

가온챔버(2A)의 측면에 물이 공급되는 연결관(6) 한쪽이 고정 장착되어 있고, 도 4를 참조하면 연결관(6) 내부에 단방향 밸브(7)가 장착되어 있다. 연결관(6) 다른 한쪽으로 물이 채워지는 용기(5)가 고정 장착된다.One side of the connecting pipe 6 to which water is supplied is fixed to the side surface of the heating chamber 2A, and referring to FIG. 4, the one-way valve 7 is mounted inside the connecting pipe 6. The container 5 which is filled with water to the other side of the connecting pipe 6 is fixedly mounted.

도 3은 도 1의 A지점을 따라 반을 절개한 절개도 이다. 도 3 및 4를 참조하면 용기(5)에 채워져 있는 물이 연결관(6)을 따라 공급되어 지면 가온챔버(2A)에 물이 채워지게 된다. 그 다음 분출히터(4)에 전원이 공급되어서 가열되면 가온챔버(2A)에 채워져 있는 물은 온도가 올라가고 일정 온도에 달하여 증발하기 시작하 는 상태인 물과 증기가 공존하는 습윤포화증기 상태가 된다. 이 습윤포화증기 상태에서 수증기압에 밀려 분출도관(2B)으로 물과 습윤포화증기가 분출된다. 분출된 물과 습윤포화증기는 분사 판(1B)에 부딪쳐 방사상으로 고르게 분포하게 되어 가열 판(2C)에 부딪치게 되고 가열히터(3)에 의해서 고온으로 된 가열 판(2C)에 의해서 습윤포화증기와 고온의 물은 더욱 가열 되어서 건조포화증기가 되어 본체 커버(1)에 형성되어 있는 개구부(1A)로 분출하게 된다. 도 3 및 4에서 도시한 바와 같이 형성되어 있는 단방향 밸브(7)의 역할은 가온챔버(2A)에서 증기압이 발생할 때 물과 습윤포화증기가 용기(5)로 유입되는 것을 차단한다. 도 4에서 도시한 바와 같이 가열 판(2C)은 돌기를 형성하고 있다. 형성된 돌기는 분출된 물이 돌기 사이에 고여지게 하여 물이 천천히 아래로 흐르게 한다. 순식간에 흐르게 되면 미처 가열되지 못한 물이 하부에 고이게 되며 가열 판(2C)에 물이 닿는 면적이 줄어들게 되어 증발속도가 느려지게 된다. 가온 챔버(2A)에 물이 증기압에 의해서 분출되어 비워지면 용기(5)로부터 연결관(6)을 통해서 다시 물이 가온 챔버(2A)로 공급된다. 가온 챔버(2A)의 물은 분출히터(4)에 의해서만 가열되어 증기압이 발생하여 분출하도록 가열히터(3)에서 충분히 멀어지게 되기 위하여 필요한 만큼, 분출도관(2B)이 길어야 한다. 분출히터(4)와 가열히터(3)에 (도시하지 않은)전기 리드의 연결과 이들 히터를 컨트롤하기 위한 타입의 전기제어회로는 주지되어 있고 본 발명의 중요한 부분을 형성하지 않으므로, 설명하지 않을 것이다.3 is a cutaway view of half cut along the point A of FIG. 3 and 4, the water filled in the container 5 is supplied along the connecting pipe 6 so that the water is filled in the heating chamber 2A. Then, when power is supplied to the blowing heater 4 and heated, the water filled in the heating chamber 2A becomes a wet saturated vapor state in which water and steam coexist in a state where the temperature rises and reaches a predetermined temperature and starts to evaporate. In this wet saturated steam state, water and wet saturated steam are ejected to the jet conduit 2B by being pushed by the steam pressure. The spouted water and the wet saturated vapor collide with the spray plate 1B and are evenly distributed radially, and hit the heating plate 2C, and the wet saturated steam with the heating plate 2C heated to high temperature by the heating heater 3 The hot water is further heated to dry saturated vapor and blown into the opening 1A formed in the main body cover 1. The role of the unidirectional valve 7 formed as shown in FIGS. 3 and 4 prevents water and wet saturated steam from entering the vessel 5 when vapor pressure occurs in the warming chamber 2A. As shown in Fig. 4, the heating plate 2C forms a projection. The formed projections cause the ejected water to accumulate between the projections, causing the water to flow slowly down. If it flows in an instant, the unheated water will accumulate at the bottom and the area where water reaches the heating plate 2C will be reduced, which will slow down the evaporation rate. When water is ejected and emptied by the vapor pressure to the heating chamber 2A, water is supplied from the container 5 to the heating chamber 2A again through the connecting pipe 6. The water in the heating chamber 2A must be long as long as necessary so that the water in the heating chamber 2A is heated only by the blowing heater 4 so as to be sufficiently far from the heating heater 3 so that the steam pressure is generated and ejected. The connection of the electrical leads (not shown) to the blow-off heater 4 and the heating heater 3 and the electric control circuit of the type for controlling these heaters are well known and do not form an important part of the present invention, and thus will not be described. will be.

본 발명에 따른 증기 발생장치는 가동시점에서 빠르게 수증기를 발생시켜 목적을 달성하기 위한 시간을 절약할 수 있으며, 종래의 증기 소독기와 같이 밀폐된 공간에서 사용할 때 필요한 양의 증기와 온도를 얻기 위해 미리 채워놓은 물이 모자랄 경우 물의 재공급이 어려우며, 남을 경우 남은 물을 배출시켜야 하는 단점이 있다. 이러한 문제점을 개량한 본 발명에 의한 증기 발생 장치의 히터를 전원공급제어로 적절히 물을 공급하여 증기를 발생시킴으로, 상기한 문제점 및 기타의 문제점이 해결된다.The steam generator according to the present invention can save time for achieving the purpose by quickly generating steam at the time of operation, in advance to obtain the required amount of steam and temperature when used in a closed space, such as a conventional steam sterilizer If the filled water is insufficient, it is difficult to resupply the water, and if left, the remaining water must be discharged. The above problems and other problems are solved by generating steam by properly supplying water to the heater of the steam generator according to the present invention, which has solved the above problems.
