Description

순간 온수기Instant water heater

본 발명은 순간 온수기에 관한 것으로, 더욱 상세하게는 원수를 간접 및 직접 2회에 걸쳐 가열하여 빠르게 온수를 공급하는 순간 온수기에 관한 것이다.The present invention relates to an instantaneous water heater, and more particularly, to an instantaneous water heater that supplies hot water quickly by heating raw water indirectly and directly twice.

일반적으로 온수기는 에너지원으로 열에너지를 발생시킨 다음, 발생한 열에너지를 사용하여 물을 가열하므로서 얻게 되는 온수를 사용하게 되는 장치이다.In general, a water heater is a device that generates heat energy as an energy source, and then uses hot water obtained by heating water using the generated heat energy.

이러한 온수 장치는 원수를 가열시키는 에너지원으로서 기름이나 가스 또는 전기를 사용하고 있다.Such a hot water device uses oil, gas, or electricity as an energy source for heating raw water.

이 중 전기를 사용하는 온수기는 소음이 없고 안전성도 우수하며, 원수를 가열하기 위한 전기적 발열체를 온수 탱크내에 설치하게 된다.Among them, the water heater using electricity has no noise and is excellent in safety, and an electric heating element for heating raw water is installed in the hot water tank.

이와 같은 온수기에 관한 대표적인 예가 하기 한국공개특허 제2008-0039214호(이하, '종래기술'이라 한다)에 개시되어 있으며, 이하 도 1을 참조하여 설명한다.A representative example of such a water heater is disclosed in the following Korean Laid-Open Patent Publication No. 2008-0039214 (hereinafter, referred to as 'prior art'), which will be described below with reference to FIG. 1.

도 1에 도시한 바와 같이, 종래기술에 따른 온수기는 직접 가열식으로 저장탱크(10)의 하부에 히터(20)가 구비되고 저장탱크(10)의 하부측과 상부측에 급수관(11) 및 급탕관(12)이 각각 연결된다.
