본 고안은 전기밥솥의 감온소자 부착구조에 관한 것으로, 특히 취사시의 온도제어와 조리물이 함입된 내솥의 수납 유무에 따른 안전장치를 겸하는 자동 스위치에 있어서, 내솥의 저면에 접촉 또는 분리되는 스위치의 수열판 저면에 사각형의 감온소자를 부착하되, 감온소자의 네 모서리부를 프레스로 압착하여 두께를 1/4 정도로 축소시키고 아울러 이 네 모서리의 안착부를 따라 접하도록 압착부와 같은 두께의 지지링을 수열판 저면둘레에 부착 고정시켜 스위치 동작시 영구자석과 감온소자의 접촉 오동작을 방지하고 또한 고가인 감온소자의 크기를 축소하여 제품의 원가절감에 기여할 수 있도록 된 감온소자 부착구조에 관한 것이다.The present invention relates to a thermosensitive element attachment structure of an electric rice cooker, in particular an automatic switch having a safety device according to the temperature control at the time of cooking and the presence or absence of the inner pot containing food, the switch which is in contact with or separated from the bottom of the inner pot Attach a rectangular thermosensitive element to the bottom of the heat sink, and press the four corners of the thermosensitive element with a press to reduce the thickness to about 1/4, and attach a support ring of the same thickness as the crimped part so as to contact the seats of the four corners. It is attached to the bottom surface of the heat receiving plate fixed to prevent the contact between the permanent magnet and the thermal element during the switch operation, and also to reduce the size of the expensive thermal element to reduce the cost of the product of the thermal element attachment structure.

일반적으로 전기밥솥의 온도제어 및 안전을 위한 자동스위치는 제1도 및 제2도와 같이 조리물이 넣어져 취사되는 시점의 내솥의 온도가 전달되는 수열판(1)과, 수열판(1) 저면에 실리콘 접착제(2)로써 접착고정되는 감온소자(3)와, 감온소자(3)가 수열판(1)에서 완전한 고정상태를 유지할 수 있도록 내주연은 감온소자(3)의 둘레 저면에 밀착되고 외주연은 수열판(1)의 둘레저면에 부착된 지지링(4)과, 영구자석(5)이 고정된 받침판(6)과, 상기 열판(1)과 받침판(6) 사이에 탄력 개재되어 일정 시점에서 감온소자(3)와 영구자석(5)이 접촉 및 분리되게 하는 스프링(7)으로써 구성되어 있다.In general, the automatic switch for temperature control and safety of the electric rice cooker is a heat receiving plate (1) and the bottom of the heat receiving plate (1) to which the temperature of the inner pot at the time when the food is put and cooked as shown in FIG. The inner periphery is in close contact with the circumferential bottom of the thermosensitive element 3 so that the thermosensitive element 3 and the thermosensitive element 3 are fixed to the heat-receiving plate 1 by the silicone adhesive 2 and are fixed to the heat receiving plate 1. The outer periphery is elastically interposed between the support ring (4) attached to the circumferential bottom of the heat receiving plate (1), the support plate (6) to which the permanent magnet (5) is fixed, and the hot plate (1) and the support plate (6). It is comprised by the spring 7 which makes the thermal element 3 and the permanent magnet 5 contact and isolate | separate at a certain time.

따라서 밥솥의 음식물 취사시 음식물이 담겨진 내솥의 온도가 수열판(1)에 전달되고 이와 동시에 수열판(1)에 부착된 감온소자(3)에 온도가 인가되므로써 온도상태에 따라 영구자석(5)이 감온소자(3)에 흡착 또는 분리되어 스위치의 ON, OFF 동작이 이루어지는 것이다.Therefore, when cooking the food of the cooker, the temperature of the inner pot containing the food is transferred to the heat receiving plate 1 and at the same time the temperature is applied to the temperature sensing element 3 attached to the heat receiving plate 1 so that the permanent magnet (5) The switch is absorbed or separated by the thermosensitive element 3 to perform ON / OFF operation of the switch.

그러나 상기와 같은 종래의 감온소자 부착상태에 의하면, 지지링(4)이 감온소자(3)로부터 돌출되어 있으므로 감온소자(3)에 영구자석(5)의 흡착시 스프링(7)의 편심 압축등에 따라 영구자석(5)이 지지링(4)에 부딪혀 걸리는 경우가 있어 흡착 상태가 정확하지 못할 뿐만 아니라 이로써 스위치의 동작을 둔화시키고 또한 스위치의 오동작을 초래하는 문제점을 갖는 것이다.However, according to the conventional thermosensitive element attached state as described above, since the support ring 4 protrudes from the thermosensitive element 3, the eccentric compression of the spring 7 when the permanent magnet 5 is adsorbed to the thermosensitive element 3, etc. Accordingly, the permanent magnet 5 may be caught by the support ring 4, so that the adsorption state may not be accurate, thereby slowing the operation of the switch and causing a malfunction of the switch.

한편 종래의 감온소자(3)는 수열판(1)의 중심반경에 가까운 길이를 갖고 부착되어 있으므로 원가상승의 한 요인으로 대두되고 있는 실정인 것이다.On the other hand, the conventional thermal element 3 is attached to have a length close to the center radius of the heat receiving plate (1) is a situation that has emerged as a factor of the cost increase.

본 고안은 영구자석의 수열판 흡착동작이 정확하게 이루어지도록 하고 아울러 고가인 감온소자의 크기를 축소시켜 제품의 원가절감을 실현할 수 있도록 하기 위함이 목적인 것으로, 이를 위하여 지지링을 감온소자 부착면으로부터 두께를 낮추고 감온소자는 그 길이를 축소시킨 것이다.The purpose of the present invention is to make the heat absorbing plate adsorption operation of the permanent magnet accurately, and to reduce the size of the expensive thermosensitive element so as to realize cost reduction of the product. Lower the temperature sensing element is to reduce its length.

이하 첨부도면에 의해 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제3도 내지 제5도에서 보는 바와 같이 음식물이 담겨진 별도의 내솥으로부터 열을 전달받는 수열판(1)과, 수열판(1)의 저면중앙에 실리콘 접착제(2)로써 부착되는 사각형의 감온소자(3a)와, 감온소자(3a)의 네모서리부 일측 각변에 요입형성된 홈(11)과, 감온소자(3a)의 네 모서리부에 감온소자의 1/4 두께가 되도록 압착 형성시킨 걸림편(12)과, 걸림편(12)과 동일한 두께로서 감온소자(3a)의 고정상태가 견고하게 유지되도록 그 걸림편(12)에 내주연이 접하면서 외주연은 수열판(1)의 저면 외측 둘레에 압입고정되는 지지링(4)과, 상기 감온소자(3a)에 흡착되는 영구자석(5)이 고정된 받침판(6)과, 받침판(6) 및 수열판(1) 사이에 탄력적으로 개재 설치되는 스프링(7)으로 구성된 것이다.As shown in FIGS. 3 to 5, the heat receiving plate 1 receives heat from a separate inner pot containing food, and a rectangular thermosensitive element attached to the bottom center of the heat receiving plate 1 with a silicone adhesive 2. (3a), a groove 11 formed in each side of the corner of the four corners of the thermosensitive element 3a, and a locking piece formed by pressing the four corners of the thermosensitive element 3a to be 1/4 thickness of the thermosensitive element ( 12) and the outer circumferential edge of the heat receiving plate 1 while the inner circumference is in contact with the locking piece 12 so that the fixing state of the thermosensitive element 3a is firmly maintained at the same thickness as the locking piece 12. A support ring (4) press-fitted into the support plate, a support plate (6) to which the permanent magnet (5) adsorbed by the thermosensitive element (3a) is fixed, and interposed elastically between the support plate (6) and the heat receiving plate (1). It is composed of a spring (7).

상기와 같은 된 본 고안은 내솥의 조리물이 취사되면서 가열온도가 수열판(1)과 함께 감온소자(3a)에 인가되고 이때의 온도상태에 따라 영구자석이 감온소자(3a)에 흡착 또는 분리되어 스위치 작동이 이루어지는 것인바, 여기서 감온소자(3a)의 걸림편(12)은 감온소자 몸체보다 두께가 1/4로 작고 또한 걸림편(12)에 접하여지는 지지링(4)의 두께 역시 걸림편(12)과 같으므로 결국 지지링(4)과 걸림편(12)의 두께의 합은 감온소자(3a) 몸체두께의 절반으로서 영구자석(5)이 지지링(4)에 걸려지는 일없이 정확하고 용이하게 흡착이 이루어지는 것이다.In the present invention as described above, the cooking temperature of the inner pot is cooked while the heating temperature is applied to the temperature sensing element 3a together with the heat-receiving plate 1, and the permanent magnet is adsorbed or separated on the temperature sensing element 3a. The switch operation is to be performed, where the locking piece 12 of the thermosensitive element (3a) is 1/4 the thickness of the thermosensitive element body and also the thickness of the support ring (4) in contact with the locking piece 12 is also caught Since the same as the piece 12, the sum of the thicknesses of the support ring 4 and the locking piece 12 is half of the body thickness of the thermosensitive element 3a so that the permanent magnet 5 is not caught by the support ring 4. Adsorption is accurate and easy.

이는 감온소자 몸체가 지지링(4)보다 돌출되어 있기 때문인 것이며 따라서 감온소자(3a)로부터 영구자석(5)이 들뜨지 않는 상태에서 매우 양호한 흡착상태를 갖는 것이다.This is because the thermosensitive element body protrudes more than the support ring 4, and thus has a very good adsorption state without the permanent magnet 5 being lifted up from the thermosensitive element 3a.

이와 같이 영구자석(5)과 감온소자(3a)의 흡착성이 향상되므로써 스위치의 작동이 보다 정확하게 이루어져 밥솥의 온도제어 또는 내솥과 외솥의 분리상태 감지 또한 정밀하게 이루어진다.As such, the adsorption of the permanent magnets 5 and the thermosensitive element 3a is improved, so that the operation of the switch is more accurate, so that the temperature control of the rice cooker or the detection of the separation of the inner pot and the outer pot is also precisely performed.

이상과 같이 본 고안은 감온소자로부터 지지링의 부착두께를 낮춤으로써 영구자석과 감온소자의 흡착동작과 아울러 스위치의 작동이 보다 정확하게 이루어지게 되었으며 고가인 감온소자의 길이를 축소시키므로써 제품의 원가절감을 실현할 수 있는 효과를 갖게 된 고안인 것이다.As described above, the present invention lowers the thickness of the support ring from the thermosensitive element, thereby adsorbing the permanent magnet and the thermosensitive element, as well as operating the switch more accurately, and reducing the cost of the product by reducing the length of the expensive thermosensitive element. The devised to have an effect that can be realized.
