본 고안은 가스레인지의 상면판에 과열이 발생하면 이를 감지하여 가스공급을 차단함과 동시에 경보음을 발하여 화상 등의 안전사고로부터 조리자를 보호하기 위한 가스레인지의 상면판 과열 방지장치에 관한 것이다.The present invention relates to an overheat prevention device of a gas stove for protecting a cooker from a safety accident such as a burn by detecting an alarm and blocking the gas supply when an overheat occurs in the gas stove upper plate.
가스레인지의 안전장치를 보면, 대체적으로 연소부의 상태를 감지하여 조리작업시 발생되는 각종 사고를 미연에 방지하기 위한 것으로 그예를 들어 설명하면, 먼저 음식물의 조리도 중 피가열물에 과열이 발생되는 것을 방지하는 것 즉, 조리자가 음식물의 조리 상태를 부주위로 잊거나 조리실을 이탈시 피가열물에 과열이 발생되고 이러한 과열상태가 장시간 지속되어 화재의 위험까지 초래하게 되는 것을 방지하기 위한 안전장치로써 주버너(1)의 중앙부에 과열감지 장치를 설치하여 음식물의 조리도중 피가열물에 필요이상의 과열이 가하열지면 과열감지 장치(11)가 이를 감지함과 동시에 기전력이 발생하여 안전변(7)을 차단시켜 불꽃이 소화되게 하거나, 또는 주버너(1)의 주연에 열감지대(12)를 설치하여 음식물의 요리도중에 외력에 의해 불꽃이 꺼지게 되면 이를 감지하여 가스의 공급을 중단되게하여 가스의 누출을 방지케한 것으로 이를 좀더 구체적으로 설명하면, 조리자가 음식물의 요리과정을 주시하지 않은 상태에서 음식물의 국물이 끓어 넘치거나 바람에 의하여 불꽃이 소화되면 가스공급이 자동적으로 중단되게하여 가스의 손실은 물론 이러한 상황이 발견되지 않고 장시간 지속될 경우 폭발 및 안전사고가 발생되는 것으로 이의 구성을 보면 주버너(1)의 주연에 열감지대(12)를 설치하여 피가열물의 국물이 넘치거나 바람에 의하여 불꽃이 꺼지면 열감지대(12)가 이를 감지함과 동시에 안전변(7)에 기전력을 전달하여 가스공급이 중단되도록한 것이다.When looking at the safety device of the gas range, it is generally to detect the state of the combustion unit to prevent various accidents occurring during cooking operation. For example, first, when the food to be cooked is overheated, That is, as a safety device to prevent the cooker from forgetting about the cooking condition of food or leaving the cooking room, the overheating of the heated object occurs and the overheating condition lasts for a long time, resulting in the risk of fire. If the overheat sensing device is installed at the center of the main burner 1 and the overheating of the food to be heated is applied during the cooking of food, the overheat sensing device 11 detects this and an electromotive force is generated to generate the safety valve 7. Block the fire to extinguish the fire, or install the heat sensing zone 12 at the periphery of the main burner (1) to extinguish the flame by external force during food cooking When it is detected, it stops the supply of gas and prevents the leakage of gas. More specifically, when the cook does not watch the cooking process of the food, the soup of the food boils or the flame is caused by the wind. When this is extinguished, the gas supply is automatically stopped so that the loss of gas, as well as such a situation, is not found, and if it lasts for a long time, an explosion and a safety accident occur. The configuration of the heat sensing zone 12 at the periphery of the main burner 1 If the broth of the heated object overflows or the flame is turned off by the wind, the heat sensing zone 12 detects this and at the same time delivers electromotive force to the safety valve 7 to stop the gas supply.
그러나 상술한 바와같은 종래의 가스레인지의 안전장치는 연소부에 외부의 작용에 의하여 발생가능한 안전사고만을 방지하기 위해 제안되었던 것으로, 주버너 및 몸체의 중앙부에 내설된 그릴버너의 사용중 연소열에 의하여 발생되는 고열이 가스레인지의 상면판에 전달되어져 상면판이 과열 상태가 되는 것을 방지하지 못하는 결점이 있었다.However, the safety device of the conventional gas range as described above has been proposed to prevent only safety accidents that may occur due to external action on the combustion section, and is generated by the heat of combustion during use of the main burner and the grill burner built in the center of the body. There was a drawback that the high heat is transmitted to the top plate of the gas cooker to prevent the top plate from overheating.
특히 그릴에서 음식물을 구이하는 과정에서 발생되는 열기가 그릴 외부로 방출하여 상면판의 전방부에 고열이 전달되어지므로써 조리자가 부주위로 과열된 상면판에 피부를 접촉하게 되면 화상을 입는 문제점이 있었다.In particular, since the heat generated during the grilling of food is released to the outside of the grill and high heat is transmitted to the front of the top plate, there is a problem of burns when the cook contacts the skin with the overheated top plate. .
본 고안은 상술한 바와같은 종래의 문제점을 감안하여 안출한 것으로 가스레인지로 음식물을 요리하는 과정에서 조리자의 피부가 접촉하기 쉬운부분, 즉, 상면판의 전방부에 근접되도록 과열감지 수단을 설치하여 가스레인지의 사용도중에 연소실에 의하여 상면판의 온도가 과열되어지면 이를 감지하여, 가스공급을 차단하여 불꽃을 소화시킴과 동시에 경보음을 발하게하여 가스레인지의 상면판에 과열이 발생되었음을 조리자에게 상기시키므로써 가스레인지 상면판의 과열로 인한 화상의 위험으로부터 조리자를 보호함을 목적으로 안출한 유용한 고안인 것이다.The present invention has been made in view of the above-described conventional problems, and by installing an overheat detection means such that the skin of the cooker is easily in contact with the cooker's skin, ie, close to the front of the upper plate, in the process of cooking food with a gas range. When the temperature of the upper plate is overheated by the combustion chamber during the use of the gas range, the cooker detects this and cuts off the gas supply to extinguish the flame and emits an alarm sound. It is a useful design designed to protect the cooker from the risk of burns due to overheating of the gas stove top plate.
본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도면의 제1도와 2도에서 4는 설치부재이다.In FIG. 1 and FIG. 2, 4 is an installation member.
이 설치부재는 주버너의 연소부(3)에 판상의 부재를 결합하고 상면판과 근접되는 위치에서 전방으로 절곡시켜 이에 상면판 과열 감지 수단(5)을 설치할 수 있도록 한 것이고, 콘트롤 판넬의 후측벽에는 전방을 향하도록 경보부재(6)를 착설하는 것이다.The mounting member is coupled to the plate-like member to the combustion section (3) of the main burner and bent forward in a position close to the upper plate to allow the upper plate overheat detection means (5) to be installed thereon. The alarm member 6 is installed on the side wall to face forward.
상기와 같이 가스레인지의 전방 실내측에 구성된 설치부재(4)와 경보부재(6)에 상면판에서 발생되는 과열을 감지하여 가스공급을 차단시키고 경보음을 울리게 하는 과열 감지 수단(5)을 연결하여 설치하는 것으로, 본 고안은 이 상면판 과열 감지 수단을 형상 기억 합금을 이용하는 방법과 바이메탈을 이용하는 두가지 방법을 제안하는 것이다.Connect the overheat detection means (5) to detect the overheat generated from the upper surface plate to the installation member 4 and the alarm member (6) configured on the front indoor side of the gas range as described above to cut off the gas supply and sound an alarm. The present invention proposes two methods using the shape memory alloy and bimetal using the top plate overheat detection means.
먼저 형상기억합금을 이용한 상면판 과열감지수단의 구성을 설명하면 다음과 같다.First, the configuration of the upper plate overheat detection means using the shape memory alloy is as follows.
도면 제2a도에 도시된 바와같이 설치부재(4)의 설치 단면을 상향으로 절곡하여 단턱부(41)를 구성한다.As shown in FIG. 2A, the mounting cross section of the mounting member 4 is bent upward to configure the stepped portion 41.
이와같이 구성된 설치부재(4)에, 상부주연에 고정편(53)을 구비하고 하부에 안내공(59)을 갖춘 원통형상의 케이스(52)를 하향으로 고정 설치하고, 상기 케이스(52)의 내부에는 형상기억합금을 이용하여 코일스프링 형상을 갖춘 구동부재(51)와 결합되게 가동접속 부재(53)를 구성하여서 된 것이다.In the mounting member 4 configured as described above, the cylindrical case 52 having the fixing piece 53 at the upper circumference and the guide hole 59 at the lower portion thereof is fixedly installed downward, and inside the case 52 The movable connection member 53 is configured to be coupled to the driving member 51 having the coil spring shape using the shape memory alloy.
이상과 같이 구성된 과열감지수단(5)에 경보 수단은 구성함에 있어서, 케이스 (52)의 내주벽의 소정위치. 즉 구동부재(51)가 상면판의 고열에 의해 수축변형되어져 가동 접속부재(53)의 상부 접지부(54)가 정지하는 위치에 경보 접속단자(56)를 고정설치하며 각 접지부와 접속단자가 통전되도록 경보부재(6)와 안전변(7)에 전원을 연결한 것이며 가동 접속부재(53)의 하부에 구성된 접지부(55)와 면접되도록 가스 개폐 접속단자(7a)를 설치하여 이루어진 것으로 그 작용 효과를 설명하면 다음과 같다.A predetermined position of the inner circumferential wall of the case (52) in the alarm means is provided in the overheat detection means (5) configured as described above. That is, the driving member 51 is contracted and deformed by the high temperature of the upper surface plate, and the alarm connection terminal 56 is fixedly installed at the position where the upper ground portion 54 of the movable connection member 53 stops. The power supply is connected to the alarm member 6 and the safety valve 7 so that the electricity is supplied to the power supply, and the gas opening / closing connection terminal 7a is installed so as to be interviewed with the ground part 55 formed at the lower part of the movable connection member 53. The effect of the operation is described as follows.
가스레인지 상면판(2)에 구동부재(51)에 기억된 설정 온도 이상으로 과열이 발생되면 구동부재(51)가 변형을 일으켜 설정된 소정의 길이로 수축 변형하게 된다.If overheating occurs in the gas cooker upper surface plate 2 above the set temperature stored in the driving member 51, the driving member 51 causes deformation and shrinkage deformation to a predetermined length.
따라서 구동부재(51)하부와 연결된 가동 접속부재(53)로 동시에 상향으로 이동하면서 가스 개폐 접속단자(7a)의 회로를 차단하여 가스공급을 중단하고 상부의 접지부와 경보 접속단자가 연결되어 경보음을 울리도록 한 것이다.Therefore, while simultaneously moving upward to the movable connecting member 53 connected to the lower part of the driving member 51, the circuit of the gas opening and closing connection terminal 7a is cut off to stop the gas supply, and the upper ground part and the alarm connecting terminal are connected to the alarm. It was supposed to ring.
이상과 같이 상면판에 발생된 과열을 감지하여 가스 공급을 중단시켜 불꽃을 소화시킨 후 시간이 경과하면서 상면판의 온도가 설정온도 이하로 낮아지면 수축 되었던 구동부재(51)가 복귀되어 경보음을 정지시키고 가스공급이 가능하게 되어 점화 스위치를 작동시키면 정상적으로 가스레인지를 사용할 수 있도록 한 것으로써 형상기억 합금의 열감지 능력을 최대한 이용하여 정확하고 반영구적인 열감지수단을 제공하는 것이다.As described above, after sensing the overheat generated in the upper surface plate and stopping the gas supply to extinguish the flame, when the temperature of the upper surface plate becomes lower than the set temperature as time elapses, the driving member 51 which has been contracted returns to the alarm sound. By stopping the gas and enabling the ignition switch to operate the gas range normally, it provides accurate and semi-permanent heat sensing means by utilizing the heat sensing capability of the shape memory alloy.
다음은 바이메탈을 이용한 과열감지수단을 설명한 것으로, 제2b도에 도시된 바와같이 비전도성 고정판(157)을 구비하고 그 상면의 일측에 접속부재(158)를 구성하여 이에 열팽창율이 서로 다른 두종류의 금속판을 마주 붙여서 된 구동부재(151)를 설치하며 타측 전, 후방에는 경보접속단자(156)와 가스개폐접속단자(17a)를 각각 입설하고 이 접속 단자와 접속부재가 통전되도록 경보부재(6)와 안전변(7)에 전원을 연결한 것으로 그 작용 효과를 설명하면 다음과 같다.The following is a description of the overheat detection means using bimetal. As shown in FIG. 2B, the non-conductive fixing plate 157 is provided, and the connection member 158 is formed on one side of the upper surface thereof, and thus, two types of thermal expansion coefficients are different from each other. A driving member 151 provided with a metal plate facing each other, and an alarm connecting terminal 156 and a gas opening / closing connecting terminal 17a are respectively installed at the front and rear of the other side, and the connecting member and the connecting member are energized. ) And the safety valve (7) is connected to the power will be described as follows.
가스레인지의 상면판에 과열일 발생되면 구동부재(151)가 변형을 일으켜 가스개폐 접속단자(17a)로부터 이완되면서 경보접속단자(156)에 접지되어 가스의 공급을 차단하여 불꽃을 소화시킴과 동시에 경보음을 발휘하도록 구성 되어진 것으로, 설치가 용이하고 제작단가가 저렴한 과열감지 수단을 제공하는 데 있다.When overheating occurs in the upper plate of the gas range, the driving member 151 deforms and relaxes from the gas opening / closing connection terminal 17a and is grounded to the alarm connection terminal 156 to cut off the supply of gas to extinguish the flame. It is configured to provide an alarm sound, and to provide an overheat detection means that is easy to install and inexpensive to manufacture.
상술한 바와같이 형상기억합금을 이용하거나 바이메탈을 이용한 가스레인지의 상면판 과열감지 수단을 상면판에 발생되는 과열을 감지하여 가스 공급을 중단하여 불꽃을 소화시킴과 동시에 경보음을 발하도록하여 과열에 의한 화상의 위험으로부터 사용자를 보호 하도록 한 유용한 고안인 것이다.As described above, the upper plate heat sensing means of the gas range using a shape memory alloy or a bimetal senses an overheat generated in the upper plate to stop the gas supply to extinguish the flame and emit an alarm sound at the same time. It is a useful design to protect the user from the risk of burns.
