Description
본 발명은 치과에서 의료기에 물을 공급할 때 저수통에 물을 일일이 갖다붓는 번거로움과 치과의료기에서 물을 쓸때마다 콤퓨레샤가 작동하는 기계적, 에너지적 손실을 없애고 공급된 물로 구강세척시 온도 조절이 곤란할뿐 아니라 용량이 적어 사용이 불편하고 구강에 사용되는 물은 좀더 청결해야 환자의 건강과 의사에 대한 신뢰도를 높일수 있기 때문에 케이스에 정수기를 장착시키고 가압펌프를 설치하고, 압력탱크를 연결하여 정수된 물을 저장하고 일정한 압력을 유지하고 압력탱크에 저장된 물을 적정 온도로 가열시켜 의료기에 온수를 공급하여 자동급수함으로서 편리하고 깨끗할뿐 아니라 원하는 온도로 물을 공급함으로서 의료기기 수명연장과치료시 구강청결과 수질에 대한 신뢰향상의 효과가 있다.The present invention eliminates the hassle of pouring water into the reservoir when supplying water to the medical device at the dentist and eliminating the mechanical and energy loss in which the compressor is operated every time the water is used in the dental device and controlling the temperature during oral washing with the supplied water. Not only is this difficult, but also the capacity is inconvenient to use, and the water used in the oral cavity should be more clean so that the patient's health and doctor's trust can be increased. Therefore, a water purifier is installed in the case, a pressure pump is installed, and a pressure tank is connected. It is convenient and clean by supplying hot water to the medical device by heating the water stored in the pressure tank to the proper temperature and automatically supplying hot water to the medical device. There is an improvement in confidence in cleanliness and water quality.
본 발명은 압력탱크를 이용한 치과용 자동급수온도조절정수장치에 관한 것으로서 더욱 상세하게는 정수기에 압력탱크와 온도조절창치를 내장시켜 정수한 물올 데워서 일정한 압력으로 자동급수할수 있고 이 정수장치와 연결하여 대기실에는 식수를 공급할수 있으며 케이스에 내장시켜 외적인 미관도 고려한 것이다. 일반적으로 정수기는 정수하고자 하는 물을 여러종류의 필터를 통과시키면서 정수하는 방식으로서 세디먼트 필터는 물속의 모래, 흙먼지, 부유물질, 녹 등을 제거하는 기능을 가지고 있으며 카본필터는 물속의 화학오염 물질을 제거하고 멤브레인으로 물속의 중금속, 세균을 제거한후 티오알 필터를 통과하면 정수된 물이 마시기에 적당하게 된다. The present invention relates to a dental automatic water supply temperature control water purification device using a pressure tank, and more particularly, built-in pressure tank and temperature control window in the water purifier to warm water purified and automatically supply water at a constant pressure, Drinking water can be supplied to the waiting room. In general, the water purifier purifies the water to be purified while passing through various kinds of filters. The sediment filter has the function of removing sand, dust, suspended matter, rust, etc. in the water, and the carbon filter has chemical pollutants in the water. After removing the heavy metals and bacteria in the water with a membrane and passing through the thioal filter, purified water is suitable for drinking.
상기와 같은 정수기는 가정용과 산업용으로 대별할 수가 있고 가정용은 일반 가정과 식당에서 산업용은 폐수처리로부터 초순수를 공급하는 첨단산업에까지 응용되고 있다. 그러나 치과치료시에 물을 많이 사용함에도 불구하고 별다른 정수처리가 없었고 설령 있다고 할지라도 별도로 정수하여 일일이 통에 갖다부어야 하며 의료시술중이라도 물이 떨어질 경우에는 시술을 중단해야 되는 등 불편할뿐 아니라 정수된 물을 사용하지 않았을 경우에는 물속의 이물질이 기기를 손상시키고 기기속에 세균이 번식할 우려가 있어 환자에게 불쾌감을 줄 뿐아니라 건강위협의 측면에서도 문제점을 지녀왔다. 또한 물을 데워주는 워머의 경우 온도조절이 되지 않고 용량이 작아 겨울에는 차갑고 여름에는 미지근한 등의 문제점을 안고 있었다고 할수 있다.Such water purifiers can be roughly classified into household and industrial applications, and households are used in general households and restaurants, and industrial applications from wastewater treatment to high-tech industries that supply ultrapure water. However, despite the use of a lot of water for dental treatment, there was no special water treatment, even if it is, even if you have to separate it separately and put it into the bucket, and even if the water drops during medical treatment, the procedure is not only inconvenient, but also inconvenient When not used, foreign matter in the water may damage the device and bacteria may grow in the device, causing discomfort to patients as well as problems in terms of health threats. In addition, the warmer that warms the water has a problem such as cold temperature in winter and lukewarm in summer because the capacity is not controlled without temperature control.
