Description

온수 역순환 방지기능을 갖춘 전기온수매트용 보일러장치{Boiler for electric hot water mat with hot water circulation prevention function} Boiler for electric hot water mat with hot water circulation prevention function}

본 발명은 온수 역순환 방지기능을 갖춘 전기온수매트용 보일러장치에 관한 것으로, 보다 상세하게는 보일러장치의 전기히터에서 가열된 온수를 배출하면서, 상기 배출된 온수가 전기히터에 역류되는 것을 방지해 제품의 고장발생을 방지해 제품의 만족도를 향상시킬 수 있도록 발명된 것이다.The present invention relates to a boiler device for an electric hot water mat having a function of preventing reverse circulation of hot water, and more particularly, to prevent the discharged hot water from flowing back to the electric heater while discharging hot water heated by the electric heater of the boiler device. It is invented to improve product satisfaction by preventing product failure.

일반적으로 전기를 이용해서 온수를 가열시키고, 상기 가열된 온수를 매트 내부에 순환시켜 난방하는 온수매트는, 크게 물을 저장하는 물탱크와, 물탱크 내부의 물을 가열하는 순환수 히팅수단과, 가열된 온수를 온수매트로 순환 공급시키는 체크밸브를 포함하는 보일러장치가 연결 구성된다.In general, a hot water mat for heating hot water using electricity and circulating the heated hot water in the mat for heating includes a water tank largely storing water, a circulating water heating means for heating water in the water tank, A boiler apparatus including a check valve for circulating and supplying heated hot water to the hot water mat is connected.

즉, 특허문헌 1에서와 같이 크게 물탱크의 유출로에는 순환수의 역류를 방지하는 역류방지구가 구비되어 순환수 히팅수단에 의해 가열 팽창된 물이 물탱크로의 역류를 방지한 다음 상기 온수매트의 순환관으로 공급되게 하는 역할을 한다.That is, as in Patent Literature 1, a reverse flow prevention port is provided in the outlet passage of the water tank to prevent reverse flow of circulating water, so that the water heated and expanded by the circulating water heating means prevents reverse flow to the water tank. It plays the role of supplying it to the circulation pipe of the mat.

그러나, 선행기술의 역류방지구는 히팅수단에 의해 가열된 순환수가 물탱크의 수용공간으로 역류되는 것을 방지할 수 있는 반면에, 상기 히팅수단과 순환관 사이에는 공간의 협소함 등으로 역류방지기능을 갖추지 못하여 순환관으로 배출된 가열된 온수가 다시 히팅수단 방향으로 역류해 고온의 온수가 재가열 됨으로서 열에 취약한 합성수지재의 온수매트 순환관이 과도하게 뜨거워져 변형되거나, 뜨거운 순환관에 의해 사용자가 놀라 제품이상에 따른 불만을 제기하는 폐단이 있었다.However, the backflow prevention device of the prior art can prevent the circulating water heated by the heating means from flowing back into the receiving space of the water tank, while the backflow prevention function is not provided due to the narrow space between the heating means and the circulation pipe. As the heated hot water discharged through the circulation pipe flows back to the heating means, the hot hot water is reheated, and the hot water mat circulation pipe made of synthetic resin, which is vulnerable to heat, becomes excessively hot and deforms, or the user is surprised by the hot circulation pipe. There was a nuisance of complaining about it.

또, 상기 순환수 히팅수단의 히팅관체와 순환관을 상호 연결시키는 제2마감구 사이에는 누수방지링이 장착되어 순환수가 누수 되는 것을 방지하는데, 상기 누수방지링의 넓은 면적이 고온의 순환수에 노출되어 장시간 사용 시에는 경화에 따른 실링효과의 저하로 이음부의 누수위험이 증가하는 문제점이 있었다.In addition, a leakage prevention ring is installed between the second closing hole connecting the heating pipe body and the circulation pipe of the circulating water heating means to prevent leakage of circulating water, and the large area of the circulating water When exposed and used for a long time, there is a problem that the risk of leakage of the joint increases due to the decrease in the sealing effect due to hardening.

Boiler device for hot water mat with improved non-powered hot water circulation and sealing performance (registration date March 31, 2016)

상기와 같은 종래기술의 문제점을 해결하기 위한 것으로서, 본 발명은 보일러장치의 전기히터와 난방배관 사이를 연결하는 온수공급 연결부재에 역류방지판을 장착하여 전기히터에서 가열된 온수가 다시 전기히터로 역류해 재가열됨과 더불어 고온의 온수에 난방배관의 변형을 방지할 수 있도록 하는데 그 목적이 있다.In order to solve the problems of the prior art as described above, the present invention is provided with a non-return plate on the hot water supply connecting member connecting between the electric heater and the heating pipe of the boiler device, so that the hot water heated by the electric heater is returned to the electric heater. The purpose is to prevent deformation of the heating pipe due to hot hot water along with reheating by reverse flow.

본 발명의 다른 목적은, 연결부재에 역류방지판을 마감덮개를 이용해 간단하게 조립 고정하며, 상기 마감덮개를 통해 실링부재가 온수와의 접촉면적을 최소화하면서도 기밀성을 증대시킬 수 있도록 하는데 있다.Another object of the present invention is to simply assemble and fix the non-return plate to the connecting member using a closing cover, and to increase airtightness while minimizing the contact area of the sealing member with hot water through the closing cover.
