전기밥솥의 워킹코일 지지구 결합구조 {holding structure of working coil supporter in electric cooker}Holding coil of working coil supporter in electric cooker

본 발명은 전기밥솥에 관한 것으로서, 보다 상세하게는 취반시 가열원으로서 유도가열 기능을 수행하는 워킹코일을 지지하기 위하여 워킹코일 베이스에 설치되는 워킹코일 지지구의 조립성을 향상시킬 수 있도록 한 전기밥솥의 워킹코일 지지구 결합구조에 관한 것이다.The present invention relates to an electric rice cooker, and more particularly, an electric rice cooker to improve the assemblability of a working coil support installed on a working coil base to support a working coil that performs an induction heating function as a heating source when cooking. It relates to a working coil support structure of the.

일반적으로, 유도(induction) 가열의 원리를 이용하여 취반을 수행하는 전기밥솥의 하부에는 워킹코일 베이스가 설치되고, 워킹코일 베이스의 하부에는 전류의 인가에 의해 유도가열을 수행하는 워킹코일이 설치되는데, 종래에는 상기 워킹코일을 워킹코일 베이스의 저면 외측에 실리콘 등과 같은 접착제를 이용하여 접착시켜 고정하였다.In general, a working coil base is installed at a lower part of an electric rice cooker for cooking using an induction heating principle, and a working coil is installed at a lower part of the working coil base to perform induction heating by applying an electric current. In the related art, the working coil is fixed to the outside of the bottom of the working coil base by using an adhesive such as silicone.

그러나, 이러한 종래의 워킹코일 설치구조에 따르면, 실리콘 등과 같은 접착제가 경화되기까지 시간이 오래 소요되기 때문에 접착제가 경화될 때까지 별도의 적치장에서 보관하여야 함으로 인해, 조립과정에서 많은 시간과 노동력을 필요로 하는 단점이 제기되었다.However, according to the conventional working coil installation structure, since it takes a long time for the adhesive such as silicone to harden, it needs to be stored in a separate stockyard until the adhesive is cured, which requires a lot of time and labor in the assembling process. Disadvantages were raised.

이러한 문제점을 해결하기 위해 접착제를 사용하지 않고 워킹코일이 설치되는 워킹코일 베이스 하면에 워킹코일의 결합상태를 지지하기 위한 별도의 지지수단을 설치하도록 한 기술이 제안된 바 있는데, 이를 도 1을 참조하여 설명하면 다음과 같다.In order to solve this problem, a technique has been proposed to install a separate support means for supporting the coupling state of the working coil on the lower surface of the working coil on which the working coil is installed without using an adhesive. The description is as follows.

도 1은 종래 기술에 따른 전기밥솥의 구조를 나타낸 종단면도이고, 도 2는 도 1의 "A"부가 결합된 상태를 나타낸 확대단면도이다.1 is a longitudinal cross-sectional view showing the structure of an electric rice cooker according to the prior art, Figure 2 is an enlarged cross-sectional view showing a state in which the "A" portion of Figure 1 combined.

상기 도면에 도시된 바와 같이, 전기밥솥은 본체(1)와, 상기 본체(1)를 개폐하는 덮개(2)를 포함하여 구성되며, 상기 본체(1)의 내부에는 오븐(10)이 수납 가능하게 설치된다.As shown in the figure, the rice cooker includes a main body 1 and a cover 2 for opening and closing the main body 1, and the oven 10 is housed inside the main body 1. Is installed.

그리고, 상기 본체(1) 내측에 설치되어 상기 오븐(10)을 지지하는 워킹코일 베이스(20)의 저면에는 워킹코일(40)이 설치되고, 오븐(10)의 측면 상부에 대응하는 본체(1) 내측에는 측면히터(50)가 설치된다.In addition, a working coil 40 is installed on a bottom surface of the working coil base 20 that is installed inside the main body 1 to support the oven 10, and the main body 1 corresponding to an upper side of the oven 10. Inside the side heater 50 is installed.

상기 워킹코일 베이스(20)의 외주면에는 워킹코일(40)이 감기는 형태로 설치되며, 상단 가장자리에는 수평으로 절곡된 테두리부(21)가 형성된다.The working coil 40 is wound around the outer circumferential surface of the working coil base 20, and an edge portion 21 bent horizontally is formed at an upper edge thereof.

상기 워킹코일 지지구(30)는 상기 워킹코일 베이스(20)의 외면과 약간의 간격을 두고 형합되며, 그 상단에는 워킹코일 베이스(20)의 테두리부(21)와 대응하여 결합될 수 있는 플랜지부(31)가 형성된다.The working coil support 30 is molded with a slight distance from the outer surface of the working coil base 20, the upper end of the plan that can be coupled corresponding to the edge portion 21 of the working coil base 20 Branch 31 is formed.

그리하여, 상기 워킹코일 베이스(20)의 하단에 워킹코일(40)을 설치시킨 상태에서 워킹코일 지지구(30)의 플랜지부(31)를 워킹코일 베이스(20)의 테두리부(21)에 대응 위치시킨 후, 대응면에 볼트 등과 같은 별도의 체결부재(S)를 체결하여 고정하였다.Thus, the flange portion 31 of the working coil support 30 corresponds to the edge portion 21 of the working coil base 20 while the working coil 40 is installed at the lower end of the working coil base 20. After positioning, it was fixed by fastening a separate fastening member (S) such as a bolt on the corresponding surface.

그러나, 전술한 종래 기술에 따르면, 워킹코일 베이스(20)의 저면에 워킹코일 지지구(30)를 고정하기 위하여 대응하는 각 결합부에 별도의 체결부재(S)를 체결해야 함으로 인해 작업공수가 증가하며, 조립에 소요되는 시간이 늘어나 생산성이 저하되는 문제점이 있었다.However, according to the above-described prior art, in order to fix the working coil support 30 to the bottom surface of the working coil base 20, a separate fastening member S must be fastened to the corresponding coupling part, so that the workmanship Increasing and increasing the time required for assembly, there was a problem that the productivity is lowered.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출한 것으로서, 본 발명은 워킹코일 베이스에 결합되는 워킹코일 지지구의 결합구조를 개선하여 별도의 체결부재를 사용하지 않고 간단하게 조립이 가능하도록 한 전기밥솥의 워킹코일 지지구 결합구조의 제공을 목적으로 한다.The present invention has been made to solve the conventional problems as described above, the present invention is to improve the coupling structure of the working coil support coupled to the working coil base to enable easy assembly without using a separate fastening member An object of the present invention is to provide a working coil support coupling structure of an electric rice cooker.
