상기 감지센서는 대한민국 특허 제0342736호(출원인 : 주식회사 이에스에스디)에 소개된 정전용량형 센서 또는 시중에서 구입할 수 있는 정전용량형 센서, 물리량에 따라 임피던스가 변하는 것으로 물체의 상태를 감지하는 센서 중 어느 하나일 수 있다.The sensing sensor is a capacitive sensor introduced in Korea Patent No. 0432736 (Applicant: ES S Co., Ltd.) or a capacitive sensor that can be purchased on the market, or a sensor that detects a state of an object by changing impedance according to physical quantity. It can be one.

이것에 의해, 본체(10)의 증기가 체크밸브(20)를 통해 호스(80)로 배출되는 것을 감지센서(81)가 감지하여, 상기 감지센서(81)가 증기감지신호를 제어부(82)로 전송하면, 상기 제어부(82)가 전원공급부(83)에서 전기히터(30)로 공급되는 전원을 차단함으로써, 전기히터(30)에 의해 본체(10)의 내부에 채워진 증기가 과열되는 것을 방지한다. 참고로, 전기히터에 의해 본체의 내부에 채워진 증기가 과열될 경우, 과열증기는 물탱크에서 플로팅 밸브장치를 통해 본체의 내부로 물이 공급되는 것을 방해하고, 상기 과열증기가 호스를 통해 온수매트로 공급될 경우, 온수매트의 호스 내부에 기포가 발생할 뿐만 아니라 온수를 증기로 증발시켜 열전달 효율이 저하되고, 온수가 순환되는 과정에서 소음이 발생하게 된다.As a result, the detection sensor 81 detects that the steam of the main body 10 is discharged to the hose 80 through the check valve 20, and the detection sensor 81 controls the steam detection signal to the controller 82. When the control unit 82 transmits power to the electric heater 30 from the power supply unit 83, the control unit 82 prevents the steam filled in the main body 10 from being heated by the electric heater 30. do. For reference, when the steam filled in the interior of the main body by the electric heater is overheated, the superheated steam prevents water from being supplied into the main body through the floating valve device in the water tank, the superheated steam through the hose hot water mat When supplied to, not only bubbles are generated inside the hose of the hot water mat, the hot water is evaporated by steam to lower the heat transfer efficiency, and noise is generated in the hot water circulation process.

상기와 같이 구성된 본 발명에 따른 전기 보일러는 다음과 같이 작동한다.The electric boiler according to the present invention configured as described above operates as follows.

물탱크(60)에 저장된 물이 플로팅 밸브장치(70)를 본체(10)의 내부로 공급되어, 본체(10)에 물이 채워지면, 상기 물이 베이퍼 코어(40)의 통공(42)을 통해 증 기발생실(50)로 공급된다. 그리고, 전기히터(30)에 전원이 공급되면, 증기발생실(50)의 체적이 본체(10)의 중공부에 상대적으로 아주 작기 때문에, 본체(10)의 중공부(11)에 채워진 물이 전기히터에 의해 가열될 때, 증기발생실(50)에 채워진 아주 작은 양의 물이 증기로 상변환되고, 상기 증기가 통공(42)을 통해 본체(10)의 중공부(11)로 배출되고, 본체(10)의 증기압이 체크밸브(20)의 스프링 탄성력 보다 크게 되면, 상기 증기가 본체(10)에 채워진 가열된 온수를 체크밸브(20)를 통해 호스(80)로 밀어내게 된다. 이때, 위에서 설명한 바와같이, 플로팅 밸브장치(70)가 증기압에 의해 물탱크(60)의 공급구(61)를 차단하게 되어, 본체(10) 내부의 증기압 및 온수가 물탱크(60)로 역류되는 것을 방지한다. 그리고, 감지센서(81)가 호스(80)로 배출되는 증기를 감지하면, 상기 제어부(82)가 전원공급부(83)에서 전기히터(30)로 공급되는 전원을 차단함으로써, 전기히터(30)에 의해 본체(10)의 내부에 채워진 증기가 과열되는 것을 방지한다.When the water stored in the water tank 60 is supplied to the inside of the main body 10 with the floating valve device 70, and the water is filled in the main body 10, the water opens the through-hole 42 of the vapor core 40. It is supplied to the steam generating chamber (50) through. Then, when power is supplied to the electric heater 30, since the volume of the steam generating chamber 50 is very small relative to the hollow portion of the main body 10, the water filled in the hollow portion 11 of the main body 10 When heated by an electric heater, a very small amount of water filled in the steam generating chamber 50 is phase-converted to steam, and the steam is discharged through the through hole 42 to the hollow portion 11 of the main body 10. When the steam pressure of the main body 10 is greater than the spring elastic force of the check valve 20, the steam is pushed out of the heated hot water filled in the main body 10 to the hose 80 through the check valve 20. At this time, as described above, the floating valve device 70 to block the supply port 61 of the water tank 60 by the steam pressure, the steam pressure and hot water inside the main body 10 flows back to the water tank 60 Prevent it. Then, when the detection sensor 81 detects the steam discharged to the hose 80, the control unit 82 cuts off the power supplied from the power supply unit 83 to the electric heater 30, the electric heater 30 This prevents the steam filled in the interior of the main body 10 from overheating.

이후, 본체(10)의 내부에서 온수가 증기압에 의해 배출되면, 본체(10)의 내부 압력이 낮아져 플로팅 밸브장치(70)가 개방되고, 물탱크(60)의 물이 본체(10)로 공급된다. Then, when the hot water is discharged from the inside of the main body 10 by the vapor pressure, the internal pressure of the main body 10 is lowered to open the floating valve device 70, the water of the water tank 60 is supplied to the main body 10 do.
