Description

열전소자를 이용한 휴대용 냉장 가열기{Portable refrigeration heater using thermoelectric element} [0001] Portable refrigeration heater using thermoelectric element [0002]

본 발명은 열전소자를 이용한 휴대용 냉장 가열기에 관한 것으로, 내부용기 하부에 설치되는 열전소자를 통해 전원의 공급량 및 상기 공급되는 전원의 전류방향을 제어하여 내부용기에 거치된 음료를 가열 또는 냉각시켜 보온 및 보냉 시킬 수 있도록 한 열전소자를 이용한 휴대용 냉장 가열기에 관한 것이다. The present invention relates to a portable refrigerator heater using a thermoelectric element, wherein a supply amount of a power supply and a current direction of the supplied power supply are controlled through a thermoelectric element provided under the inner container to heat or cool the beverage stored in the inner container, And a portable refrigerator heater using a thermoelectric element that can be cooled.

일반인들의 평균적인 여가시간 및 건강에 관한 관심이 증가됨에 따라 인체에 큰 무리를 주지 않고 쉽게 즐길 수 있는 유산소 운동이 널리 권장되고 있고 이에 따라 수분 섭취를 위한 휴대용 용기가 많이 필요하게 되었다.. As the average leisure time and health concern of the general public increases, aerobic exercise which is easy to enjoy without giving a lot of weight to the human body is widely encouraged, and accordingly, a portable container for water ingestion is needed.

종래의 기술에 따른 대부분의 보온병은 보온 및 보냉 기능만이 가능한 구조가 전부라 할 수 있다. 이러한 종래의 보온병은 일정 시간이 지나게 되면 내외의 온도 차에 의해 미지근한 물로 변하게 되어 장시간 동안 보온 및 보냉 기능을 유지할 수 있는 수단이 없기 때문에 가격이나 부피 및 중량 대비 그 효용성에는 한계가 있다. Most of the thermos bottles according to the prior art are all the structures that can only perform the functions of keeping warm and cold. Such a conventional thermos bottle is transformed into lukewarm water by a temperature difference between the inside and outside of a certain time, and there is no means to maintain the insulated and insulated function for a long time.

특히, 종래의 보온 용기는 동절기나 하절기에는 내부용기와 외기의 온도차 심해 내용물이 보다 빠르게 발열되거나 흡열이 이루어져 미진근하게 변하는데 그리 오랜 시간이 걸리지 않게 된다. 이에 따라, 필요시 원하는 온도 상의 내용물을 마실 수 없다는 문제가 있다. Particularly, in the conventional warming container, in the winter season and the summer, the deep temperature difference between the inner container and the outside air is heated more rapidly or endothermically, and thus it does not take much time. Accordingly, there is a problem that the contents on the desired temperature can not be consumed when necessary.
