본 고안은 가스렌지의 과열방지 장치에 관한 것으로 릴리즈(Release)를 이용하여 과열방지 장치의 고정접점의 위치를 상, 하 유동케 변동되도록하여 과열방지 장치가 작동하는 온도를 임의로 조절하는 가스렌지의 과열방지장치에 관한 것이다.The present invention relates to an overheat prevention device for a gas stove. The release of the gas stove for arbitrarily controlling the operating temperature of the overheat prevention device by changing the position of the fixed contact point of the overheat prevention device by using a release. It relates to an overheat prevention device.

종래의 경우 도면 제3도와 같이 과열방지장치의 열감지부(51)가 일정온도 이상이 되면 가열방지 장치의 바이메탈(52)이 변형되면서 누름봉(53)이 판스프링(54)의 변위량을 가동접점(55)에 전달되어 가동접점(55)이 고정접점(66)에서 떨어지면서, 열전대(57)의 열기전력을 차단하여 콕크(58)의 전자변(59)의 자석 성질을 잃게하여 스프링(58a)의 탄발력에 의하여 패킹(58b)이 콕크(58)의 가스인입구를 막아 가스를 차단함에 있어, 열감지부(51)의 고정접점(56)이 완전히 고정되어있고 바이메탈(52)로 일정금속으로 되어있어, 일정온도에서만 과열방지 장치가 작동 하였었다.In the conventional case, as shown in FIG. 3, when the heat sensing unit 51 of the overheat protection device is at a predetermined temperature or more, the bimetals 52 of the heat protection device are deformed, and the pressing rod 53 moves the displacement amount of the leaf spring 54. And the movable contact 55 is dropped from the fixed contact 66, thereby interrupting the thermoelectric power of the thermocouple 57 to lose the magnetic properties of the electromagnetic side 59 of the cock 58, the spring 58a. When the packing 58b blocks the gas inlet of the cock 58 to block the gas due to the elastic force, the fixed contact 56 of the heat sensing unit 51 is completely fixed and is made of a constant metal by the bimetal 52. Therefore, the overheat protection device was operated only at a certain temperature.

이때에 요리를 요리시 요리의 종류에 관계없이 요리가 탈뿐 아니라 열전도가 나쁜 조리구 등을 사용시에는 요리가 덜익는 문제점이 발생하였었다.At this time, when cooking, regardless of the type of cooking, when cooking is used as well as cooking burner bad heat conduction, there was a problem that cooking is less ripe.

이에 본 고안은 종래의 문제점을 해결하기 위하여 과열방지 장치의 고정접점을 가변시킬수 있도톡 함으로써 판스프링에 초기 접점력을 변화시켜 가동접점과 고정접점의 이탈을 조절할 수 있도록 한것인바 첨부도면에 의거하여 구성 및 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention is designed to change the fixed contact of the overheat prevention device to solve the problems of the prior art by changing the initial contact force to the leaf spring to adjust the departure of the movable contact and the fixed contact based on the accompanying drawings If described in detail the configuration and the effect as follows.

온도조절손잡이(1)와 구동캠(2)를 구동축(3)으로 연결하고, 릴리즈(4)의 양단을 브라켓(5), (5')에 고정나사(6), (6')로 고정시키고, 릴리즈(4)내의 심선(7)은 구동캠(2)과 고정접점(8)과 연결시켜 구성된 장치구조로써, 미설명부호 9는 점화손잡이, 10은 동체, 10a는 패킹, 10b는 전자변, 10c는 스프링, 11은 버너부, 12는 열감지부, 12a는 바이메탈, 12b는 누름봉, 13은 판스프링, 13a는 가동접점, 14는 슬리브, 15는 열전대이다.Connect the temperature control knob (1) and the drive cam (2) to the drive shaft (3), and fix both ends of the release (4) to the brackets (5) and (5 ') with fixing screws (6) and (6'). The core wire 7 in the release 4 is a device structure formed by connecting the drive cam 2 and the fixed contact 8, wherein reference numeral 9 denotes an ignition knob, 10 a fuselage, 10a a packing, and 10b an electronic valve. , 10c is spring, 11 is burner part, 12 is heat sensing part, 12a is bimetallic, 12b is push rod, 13 is leaf spring, 13a is movable contact, 14 is sleeve and 15 is thermocouple.

여기서 온도조절손잡이(1)는 기기의 전면 소정위치에 부설되며, 온도조절손잡이(1)와 구동캡(2)은 도면 제2a도에 도시된 바와같이 동일축상에 연결된다.Here, the temperature control knob 1 is attached to a predetermined position on the front of the device, the temperature control knob 1 and the drive cap 2 is connected to the same axis as shown in Figure 2a.

첨부도면 제1도와 같이 가스렌지 점화시 점화손잡이(9)를 누르면 콕크동체(10)의 패킹(10a)이 밀리면서 가스통로가 개방되여, 이와 동시에 가스가 개방된 통로를 따라 버너부(11)에 공급되어 연소되면서 열을 발생하므로 열전대(15)를 가열시켜 열기전력으로 개폐밸브에 연결된 전자변(10b)을 구동시켜 개폐밸브의 개방상태를 유지시킴으로써 버너부(11)에 점화중인 상태에서는 가스공급이 지속되게하고, 가열방지 장치의 열감지부(12)가 조리기구의 밑면과 접촉되어 조리기구가 일정온도 이상이 되면, 가열방지장치의 바이메탈(12a)이 변형되면서 누름부(12b)이 판스프링(13)의 변위량을 가동접점(13a)에 전달하여 가동접점(13a)이 고정접점(8)에서 떨어지면서, 열전대(15)의 열기전력을 차단하여 콕크동체(10)의 전자변(10b)의 자석성질을 잃게되어 스프링(10c)의 탄발력에 의해 패킹(10a)이 가스인입구를 막아 가스를 차단하여 조리기구의 과열되는 것을 방지하는 장치구조에 있어, 고정접점(8)을 상, 하 유동가능케, 설치시켜 고정접점(8)과 가동접점(l3a)이 떨어지는 온도를 조절하도록 된것으로써, 조리 기구를 가스렌지 본체에 올려놓고 조리기구의 밑면과 과열방지 장치의 열감지부(12)에 접촉시키고, 과열방지장치가 작동하는 온도를 높이려면 도면 제2a도와 같이 가스렌지 본체에 정착된 과열방지 온도조절손잡이(1)를 시계방향인 "X"방향으로 돌리게 되면 구동축(3)에 의해 연결된 구동캡(2)이 시계방향인 "X''방향으로 회전되므로 이(구동캡)이 일단이 연결된 릴리즈(4)의 심선(7)이 "X"방향으로 밀리면서 심선(7)이 상단에 수직상태로 고정된 고정접점(8)이 상방향으로 이동되면서 판스프링(13)를 변형하여 가동접점(13a)을 "T"만큼 상향 이동시켜 접촉하게되어 과열방지장치가 작동하는 온도는 고정접점(8)이"T"만큼 이동한 양만큼 판스프링(13)을 밀면서 가동접점(13a)과 접촉하고 있기 때문에 "T"만큼의 바이메탈(12a)의 변형량이 커야하므로 가동접점(13a)과 고정접점(8)이 떨어지는 온도가 높아지게 되므로 가열방지장치가 작동하는 온도를 높게 조절할 수 있다.When the ignition knob 9 is pressed when the gas stove is ignited as shown in FIG. 1, the gas passage is opened while the packing 10a of the cock body 10 is pushed, and at the same time, the burner part 11 is along the passage where the gas is opened. Since the heat is supplied to the combustion chamber to generate heat, the thermocouple 15 is heated to drive the electromagnetic valve 10b connected to the on / off valve with thermoelectric power to maintain the open state of the on / off valve, thereby supplying gas in the state of ignition to the burner unit 11. If the heat detection unit 12 of the heating prevention device is in contact with the bottom surface of the cooking utensil and the cooking utensil is above a certain temperature, the bimetal 12a of the heating prevention device is deformed while the pressing part 12b of the heating spring is deformed. The displacement amount of (13) is transmitted to the movable contact (13a), the movable contact (13a) falls from the stationary contact (8), the thermoelectric power of the thermocouple (15) is cut off, so that the electromagnetic side (10b) of the cock body (10) Magnetic properties are lost and springs of spring 10c In the device structure of the packing (10a) to block the gas inlet to block the gas to prevent overheating of the cookware, the fixed contact (8) can be moved up and down, and installed so that the fixed contact (8) and the movable contact By adjusting the temperature at which (l3a) falls, the cooking utensil is placed on the main body of the stove, and the bottom of the cooking utensil is brought into contact with the heat sensing unit 12 of the overheat prevention device, and to increase the temperature at which the overheat prevention device operates. As shown in FIG. 2A, when the overheat prevention temperature control knob 1 fixed to the gas stove body is turned clockwise in the "X" direction, the driving cap 2 connected by the drive shaft 3 is in the clockwise "X" direction. Rotational direction of the fixed contact 8 with the core 7 being vertically fixed to the upper end while the core 7 of the release 4 having one end (drive cap) connected to it is pushed in the "X" direction. As the plate spring 13 is deformed, the movable contact 13a is moved to " T " "T" is moved upwards and the temperature at which the overheat prevention device operates is "T" because the fixed contact 8 is in contact with the movable contact 13a while pushing the leaf spring 13 by the amount moved by "T". Since the deformation amount of the bimetal 12a must be large, the temperature at which the movable contact 13a and the fixed contact 8 fall is increased, so that the temperature at which the heating prevention device operates can be adjusted high.

과열방지장치가 작동하는 온도를 낮게하려면 도면 제2b도에 도시된 바와같이 온도조절손잡이(1)를 시계 반대방향인 "Y" 방향으로 돌리게되면 구동축(3)을 통해 구동캠(2)이 시계반대방향인 "Y" 방향으로 회전됨에 따라 이에 편심위치에 일단이 고정된 릴리즈(4)내의 심선(7)이 "Y" 방향으로 이동되며, 이와 동시에 심선(7)에 고정된 고정접점(8)이 하방향으로 이동되면서 고정접점(8)를 "T"만큼 이동한 양만큼 판스프링(13)을 하향시켜 가동접점(13a)과 고정접점(8)이 접촉하고 있기 때문에 바이메탈(12a)의 적은 변위량에도 고정접점(8)과 가동접점(13a)이 이탈되어 열전대(12)의 열기전력을 차단하여 패킹(10a)이 콕크동체(10)의 가스인입구를 막아 버너부(11)를 소화시켜 과열을 방지하여주게 되는 것이다.To lower the temperature at which the overheat protection device operates, as shown in FIG. 2B, when the temperature control knob 1 is turned in the counterclockwise “Y” direction, the drive cam 2 is clocked through the drive shaft 3. As it is rotated in the opposite direction "Y", the core 7 in the release 4 having one end fixed in the eccentric position is moved in the "Y" direction, and at the same time the fixed contact 8 fixed to the core 7 ) Moves downward so that the leaf spring 13 is moved downward by the amount of the fixed contact 8 moved by "T", so that the movable contact 13a and the fixed contact 8 are in contact with each other. Even if the displacement amount is small, the fixed contact 8 and the movable contact 13a are separated to cut off the thermoelectric power of the thermocouple 12 so that the packing 10a blocks the gas inlet of the cock body 10 to extinguish the burner part 11. It will prevent overheating.

이와같이 본 고안 고정접점(8)을 자유로이 상하이동이 가능하므로 과열방지장치가 작동하는 온도를 자유로이 조절할수 있어 요리종류와 조리기구의 종류에 따라 적성온도를 맞추어 알맞은 요리를 할수 있을뿐 아니라, 자동적으로 가스공급을 차단시켜 과열에 의한 화재의 위험은 물론 불필요한 연료의 낭비를 방지할수 있는 효과를 얻을 수 있다.In this way, the fixed contact point (8) of the present invention can be freely moved to Shanghai, so it is possible to freely adjust the temperature at which the overheat prevention device operates, so that not only the suitable temperature can be adjusted according to the type of cooking and the type of cooking utensils, but also the gas automatically. By shutting off the supply, the risk of fire due to overheating and unnecessary waste of fuel can be prevented.
