전기 주전자용 발열체Heating element for electric kettle

제1도는 본 고안이 주전자저면에 부착된 상태의 단면도.1 is a cross-sectional view of the present invention attached to the bottom of the kettle.

제2도는 종래 고안의 단면도.2 is a cross-sectional view of a conventional design.

제3도는 종래 고안의 단면도.3 is a cross-sectional view of a conventional design.

제4도는 본 고안의 분해 사시도.4 is an exploded perspective view of the present invention.

본 고안은 전열선을 매립한 상태로 주전자저면에 부착 사용케된 전기주전자용 발열체에 관한 것으로 수명이 연장되고 사용이 편리한 효과를 얻음을 목적으로 안출한 고안에 관한 것이다.The present invention relates to a heating element for electric kettle used to be attached to the bottom of the kettle in a state in which the heating wire is buried, and relates to the design devised for the purpose of obtaining the effect of extending the life and easy to use.

종래 이와 같이 주전자 저면에 부착되도록 한 전기발열체에 있어서는, 주벽내에 일개의 전열체를 매립한 상태로 알루미늄합금을 컵 형상으로 주조하여 사용하므로서(제2도 참조)이 알루미늄합금의 취약성 및 주조시 형성되는 미세공으로의 수분침투에 의하여 발열체 자체가 부식되는 등 그 수명이 길지못하였을 뿐아니라, 주전자저면에 착설할시에 넛트등의 조임력에 의하여 발열체상측 고정부에 형성된 나조가 쉽게 손상되는등의 결점이 있었으며, 또한 이 1개의 전열체를 매립하였기 때문에 100v 또는 220v전원 전용으로만 사용이 가능하였다.Conventionally, in the electric heating element that is attached to the bottom of the kettle, the aluminum alloy is cast in a cup shape while one heat-transfer body is embedded in the main wall (see FIG. 2). Not only did the lifespan of the heating element itself corrode due to the water penetration into the micropores, but also the screw, which is easily damaged by the tightening force of the heating element due to the tightening force such as nuts, when it is installed on the bottom of the kettle. In addition, since this one heating element was embedded, it could be used only for 100v or 220v power supply.

또한 종래의 전지주전자용 발열체중 위에 기술한것 이외에 알루미늄합금이 갖는 부식 및 취약성의 결점 제거하기 위하여, 비교적 내약품성등의 내부식성이 강하며 기계적 강도가 높은 스테인리스 스틸등의 금속으로 컵(cup)을 형성시킨 다음 이를 같은 형상의 금속제 컴 내부에 삽입한 후 이 금속제컵 주위에 1개의 절열체를 고정시켜서 된것도 있으나 (제3도 참조)이와 같은 발열체는 스테인 리스스틸컵과, 금속제컵 또한 전열체등을 서로 결합시킬수시의 경납땜을 이용하여야 되는 등의 그 제조장치의 고가내지는 제조상의 복잡성이 존재하는 등의 겸점이 있다.In addition to the above-described heating elements for battery kettles, in order to eliminate the defects of corrosion and fragility of aluminum alloys, the cups are made of metal such as stainless steel, which has high corrosion resistance and high mechanical strength. It is sometimes made by inserting it into a metal comb of the same shape and then fixing one heat sink around the metal cup (see Fig. 3), but this heating element is a stainless steel cup and a metal cup. There is a merit such as high manufacturing complexity of the manufacturing apparatus, such as the use of brazing at the time of joining the bodies and the like together.

본원 고안은 이와 같은결점을 제거하고, 수명이 보다 연장되고 사용이 편리한 전기주전자용 발열체를 안출한 것인바 첨부도면에 의하여 그 구성 및 효과를 상술하면 다음과 같다.The present invention removes these defects, and the life of the electric kettle is extended to a longer life and easy to use, and the construction and effect by the accompanying drawings in detail as follows.

주면에 탭(tap)(3')을 형성시킨 스테인리스 스틸 컵(3)을 형성시키고 이 컵의 외부에 2개의 전열선(4)(4')를 매립한 상태로 알루미늄 합금주조체(2)를 형성시켜서 된 것이다.The aluminum alloy casting body 2 is formed with a stainless steel cup 3 having a tap 3 'formed on its main surface and two heating wires 4 and 4' embedded in the outside of the cup. It was formed.

이와 같이된 본 고안에 있어서, 주전자(1)의 내부에 있는 물과 직접 접촉되는 부분에 스테인리스 스틸과 같은 내약품성 및 기계적 강도가 높은 금속제로 형성시킨 컵(3)이 위치케 되므로 이 컵자체가 장기간 사용에 의하여도 수분이 침투되거나 또는 부식되는 경우가 없으며, 이에 따라 전열체(4)(4')를 매립상태로 주조형성된 알루미늄 합금주조체(2) 내부에 형성된 미세공에도 수분이 침투되어 부식되는 경우가 없게된다. 또한 스테인리스 스틸컵(3)의 상단부에 나조를 형성시켜 넛트(5)로 주전자저면(1')에 고정시킬시에도 이 나조가 손상되는 등의 결함이 없게되며, 컵(3)의 외주면 전체에 탭(3')를 형성시키므로서 알루미늄 합금 주조체(2)와의 결합이 강력히 이루어짐은 물론 전열체(4)(4')로 부터의 열흡수 면적이 넓은 이점이 있다.In the present invention as described above, since the cup 3 formed of metal having high chemical resistance and mechanical strength, such as stainless steel, is placed at the portion in direct contact with water in the kettle 1, the cup itself is No moisture penetrates or corrodes even after long-term use. Accordingly, moisture penetrates into the fine pores formed in the aluminum alloy casting body 2 in which the heat-transfer bodies 4 and 4 'are embedded. There is no case of corrosion. In addition, a screw thread is formed at the upper end of the stainless steel cup 3 so that the screw thread is not damaged when the nut 5 is fixed to the bottom 1 'of the kettle, and the entire outer peripheral surface of the cup 3 is not damaged. By forming the tab 3 ', the bonding with the aluminum alloy casting 2 is made strong, and the heat absorption area from the heat transfer bodies 4 and 4' is wide.

알루미늄 합금주조체(2)내에는 2개의 전열체(4)(4')를 매립시켰으므로 110v 또는 220v를 선택하여 사용할수 있다.Since two heat transfer bodies 4 and 4 'are embedded in the aluminum alloy casting body 2, 110v or 220v can be selected and used.

도면중 미설명 부호 6, 6'는 가스켓이다.In the drawings, reference numerals 6 and 6 'denote gaskets.

도면중 제2도와 제3도는 종래의 전기주전자용 발열체로서, 5는 넛트, 1'는 주전자 저면, 4는 전열체, 3은 금속제 컵, 15는 철판이다. 제3도에서 컵(3)과 철판(15) 및 전열체(4)사이에는 경납땜으로 서로 결합되어 있다.2 and 3 are conventional heating elements for electric kettles, 5 is a nut, 1 'is a bottom of a kettle, 4 is a heating element, 3 is a metal cup, and 15 is an iron plate. In FIG. 3, the cup 3, the iron plate 15, and the heat transfer body 4 are bonded to each other by brazing.

이와 같이 본원 고안은 수명의 연장되고 사용이 편리한 장점이 있다.As such, the present invention has the advantage of extending the life and convenience of use.
