The body case 50 in which the air pipe 54 is installed to discharge the generated steam, and the water level in which a number of water level measuring sensors 62 are installed to supply water by measuring the variable level in the body case 50 The measuring unit (water level meter) 60 is installed to be connected to the body case 50 and the steam supply pipe 56a and the connection pipe 56b.

본 발명의 다른 목적은 별도의 물공급수단인 급수펌프 등이 필요없게 되어 저용량 스팀 보일러의 제조원가를 절감함과 아울러 최소의 소비전력이 소요됨과 동시에 최적의 순수한 증기만을 공급할 수 있도록 하는 데 있다.Another object of the present invention is to reduce the manufacturing cost of a low-capacity steam boiler by eliminating the need for a separate water supply means, such as a water supply pump, and to supply only optimal pure steam while requiring minimal power consumption.

상기와 같은 목적을 달성하기 위한 본 발명은, 상부로 가열수단의 가열에 의해 발생된 증기를 배출할 수 있도록 송기관이 설치된 몸체케이스와, 그 몸체케이스 내의 가변수위를 측정하여 물을 공급할 수 있도록 제어부와 연결된 다수의 수위측정센서가 설치된 수위측정부가 상기 몸체케이스와 증기공급관 및 연결관으로 연결되도록 설치된 저용량 스팀 보일러에 있어서, 상기 수위측정부의 상부와 상기 수위측정센서의 감지신호에 의해 제어부를 통하여 작동되는 전자개폐밸브가 설치된 증기공급관을 연통되게 설치하고, 하부에는 체크밸브가 설치된 물배출관을 상기 몸체케이스와 연통되도록 설치하며, 측면에는 체크밸브가 설치된 물급수관이 외부의 수도관과 연결되게 설치되는 급수통으로 구성된 급수부를 구비하여서 된 것을 특징으로 한다.In order to achieve the above object, the present invention provides a body case in which a ventilation pipe is installed to discharge steam generated by heating of a heating means to the top, and water can be supplied by measuring a variable level in the body case. In a low-capacity steam boiler installed such that a water level measuring unit in which a plurality of water level measuring sensors connected to a control unit is installed is connected to the body case, a steam supply pipe, and a connection pipe, the upper portion of the water level measuring unit and a sensing signal of the water level measuring sensor are used through the controller A steam supply pipe with an actuated electronic switch valve is installed in communication, a water discharge pipe with a check valve installed at the bottom is installed to communicate with the body case, and a water supply pipe with a check valve installed at the side is installed to be connected to an external water pipe. It characterized in that it is provided with a water supply unit consisting of a water supply tank.

본 발명은 저용량 스팀 보일러의 물공급을 폐회로를 구성한 상태에서 내부의 압력변화에 따라 발생된 증기만큼의 보충수를 지속적으로 공급할 수 있도록 함으로써, 별도의 공급수단인 급수펌프 등이 필요없게 되어 보일러의 제조원가를 절감함과 동시에 최소한의 소비전력으로 보충수를 공급할 수 있는 효과를 갖게 되는 것이다.The present invention enables the supply of water from a low-capacity steam boiler to be continuously supplied as much as the steam generated by the internal pressure change in a closed circuit, thereby eliminating the need for a separate supply means, such as a feed water pump. It has the effect of reducing manufacturing cost and supplying make-up water with minimum power consumption.
