Description

전기 압력밥솥 겸용 조리기의 안전밸브를 겸한 솔레노이드밸브장치Solenoid valve device that serves as safety valve for electric pressure cooker

본 발명은 취사 및 찜 등의 조리를 할 수 있는 전기 압력밥솥 겸용 조리기에 관한 것으로,The present invention relates to an electric pressure cooker combined cooker capable of cooking and steaming,

특히, 전기 압력밥솥 겸용 조리기에서 뚜껑을 닫고 취사 및 찜 등의 조리를 할 때 내부의 고압증기가 조리중에 미세하게 배출되는 것을 방지하고, 조리가 완료되면 내부의 고압증기를 신속하게 배출할 수 있을 뿐만 아니라, 솔레노이드장치의 고장이나 콘트롤부의 오동작으로 전기 압력밥솥 겸용 조리기의 내부 압력이 허용압력 이상으로 높아지면 별도의 동력없이 내부압력이 배출되도록 하는 전기 압력밥솥 겸용 조리기의 안전밸브를 겸한 솔레노이드밸브에 관한 것이다.In particular, when cooking the cooker and cooking by closing the lid in the cooker combined with an electric pressure cooker to prevent the internal high-pressure steam is discharged fine during cooking, it is possible to quickly discharge the high-pressure steam inside when cooking is completed In addition, when the internal pressure of the electric pressure cooker combined cooker increases due to a malfunction of the solenoid device or a malfunction of the control unit, the internal pressure is discharged without a separate power. It is about.

일반적으로 전기 압력밥솥 겸용 조리기는 밥솥용기에 조리대상물을 담고 조리를 할 때 그 밥솥용기와 뚜껑사이의 내부에 고온, 고압상태가 유지될 수 있도록 기밀성이 절대 요구되었으며, 상기와 같은 요구 사항을 충족시키기 위하여 밥솥용기와 뚜껑의 결합부에 실리콘패킹을 구비하고 그 밥솥용기와 뚜껑은 개폐가능하게 구성하여 고온, 고압이 요구되는 취사시에 밥솥용기 내부가 기밀성을 유지하도록 하고 있다.In general, an electric pressure cooker combined cooker is absolutely required for airtightness so that a high temperature and a high pressure state can be maintained between the cooker container and the lid when cooking a cooking object in a cooker container, and meets the above requirements. In order to ensure that the packing portion of the rice cooker container and the lid is provided with a silicon packing and the rice cooker container and the lid is configured to open and close to maintain the airtightness inside the cooker container when cooking high temperature, high pressure is required.

또한, 상기와 같이 기밀상태를 유지시켜 취사 등의 조리를 한 후에는 내부의 고압증기를 배출시키고 조리된 음식을 먹을 수 있도록 하기 위하여 솔레노이드밸브가 뚜껑본체에 구비되고 있다.In addition, the solenoid valve is provided in the lid body to maintain the airtight state as described above to discharge the high-pressure steam inside and to cook the cooked food after cooking such as cooking.

그러나, 상기와 같은 종래의 솔레노이드밸브는 전기 압력밥솥 겸용 조리기로 취사를 하면 그 내부에 증기압력이 형성되면서 그 증기압력이 플런저를 밀어올려 밀폐시키는 것이므로 전기 압력밥솥 겸용 조리기내에서 솔레노이드밸브의 플런저를 밀어 올릴 수 있는 증기압력이 형성되고, 그 증기 압력에 의해 플런저가 상승되어 솔레노이드밸브를 밀폐시키기 전까지는 전기 압력밥솥 겸용 조리기내에서 형성되던 증기 압력이 외부로 유출되는 현상이 발생되어 취사시간이 길어지는 문제점이 있었다.However, in the conventional solenoid valve as described above, when cooking with an electric pressure cooker combined cooker, since the steam pressure is formed therein, the steam pressure pushes up the plunger to seal the plunger of the solenoid valve in the electric cooker combined cooker. The steam pressure that can be pushed up is formed, and the steam pressure generated in the cooker combined with the electric pressure cooker is released to the outside until the plunger is raised by the steam pressure and the solenoid valve is closed. There was a losing problem.

또한, 취사가 완료된 후 제어회로에 의해 전자석에 전원이 인가되면 플런저가 하강하면서 솔레노이드밸브를 개방하고 그에 따라서 내부의 고압증기가 배출되어 조리된 음식을 먹을 수 있도록 한 것이므로 제어회로에 고장이나 에러가 발생된 경우에는 고압증기가 배출되지 않을 뿐만 아니라, 고압증기가 배출되지 않는 상태에서 사용자가 부주의로 뚜껑을 열게 되면 뚜껑이 내부 압력에 의해 폭발하듯이 열리게 되고 내부의 고압증기는 열린 뚜껑을 통해 급격하게 배출되므로 사용자가 고압증기에 의해 화상을 입게 되는 문제점이 있었다.In addition, when power is supplied to the electromagnet by the control circuit after the cooking is completed, the plunger descends to open the solenoid valve, and accordingly, the internal high pressure steam is discharged so that the cooked food can be eaten. In case of occurrence, not only the high pressure steam is discharged, but if the user inadvertently opens the lid while the high pressure steam is not discharged, the lid is opened as if it is exploded by the internal pressure, and the internal high pressure steam is suddenly opened through the open lid. There is a problem that the user is burned by high pressure steam so as to be discharged.

한편, 상기와 같은 문제점들을 해소하기 위한 방안으로 전기 압력밥솥 겸용 조리기에 상기와 같은 솔레노이드밸브와 함께 별도의 안전밸브를 설치하여 전기 압력밥솥 겸용 조리기 내부에 이상 고압이 발생되면 그 압력에 의해 안전밸브가 열리면서 고압증기를 배출할 수 있도록 하였으나, 이는 안전밸브 내부에 구비된 플런저를 코일스프링으로 지지하고 있다가 그 코일스프링의 탄성력보다 큰 압력이 플런저에 작용하면 안전밸브가 열리도록 한 것이므로 전기 압력밥솥 겸용 조리기를 장기간 사용하면 코일스프링의 탄성력이 저하되거나 코일스프링내에 이물질이 끼면서 정상적인 작동이 되지 않는 문제점이 있었을 뿐만 아니라, 하나의 전기 압력밥솥 겸용 조리기에 솔레노이드밸브와 안전밸브를 2중으로 설치해야 하므로 생산 원가가 상승되는 문제점이 있었다.On the other hand, in order to solve the above problems by installing a separate safety valve with the solenoid valve in the electric pressure cooker combined cooker as described above, if abnormal high pressure is generated inside the cooker combined electric pressure cooker safety valve by the pressure The pressure cooker was able to discharge the high pressure steam as it was opened, but this was supported by the coil spring for the plunger provided inside the safety valve, and when the pressure greater than the elastic force of the coil spring acted on the plunger, the safety valve was opened. If the cooker is used for a long time, the elastic force of the coil spring is reduced or foreign matter is caught in the coil spring, which causes the normal operation. In addition, the solenoid valve and the safety valve must be installed twice in one electric pressure cooker. The door to rising production cost It was dots.

따라서, 본 발명의 목적은 전기 압력밥솥 겸용 조리기의 뚜껑에 설치되는 솔레노이드밸브를 취사 또는 조리가 시작되어 끝날 때까지 전자석의 힘으로 닫아 놓고 취사 또는 조리가 끝났을 때는 전자석의 코일에 공급되는 전원을 차단하여 코일스프링의 힘에 의해 밸브가 열리도록 함으로서 뚜껑을 닫고 취사 및 찜 등의 조리를 할 때 내부의 고압증기가 조리중에 미세하게 배출되는 것을 방지할 수 있고, 조리가 완료되면 내부의 고압증기를 신속하게 배출할 수 있을 뿐만 아니라, 솔레노이드밸브의 플런저 상단에 플랜지가 구비된 밸브캡을 설치함으로서 솔레노이드밸브의 제어불능시 그 밸브캡이 안전밸브의 역할을 할 수 있도록 한 전기 압력밥솥 겸용 조리기의 안전밸브를 겸한 솔레노이드밸브장치를 제공함에 있다.Therefore, an object of the present invention is to close the solenoid valve installed on the lid of the electric pressure cooker combined cooker with the power of the electromagnet until the cooking or cooking starts and shut off the power supplied to the coil of the electromagnet when cooking or cooking is finished By opening the valve by the force of the coil spring, it is possible to prevent the internal high pressure steam from being discharged finely during cooking when the lid is closed and cooking and steaming. In addition to the quick discharge, the valve cap with a flange is installed on the top of the plunger of the solenoid valve, so that when the solenoid valve is out of control, the valve cap can act as a safety valve. Provided is a solenoid valve device that also serves as a valve.

이러한 본발명의 목적은 솔레노이드밸브에 구비된 전자석으로 플런저를 하향 이동시켜 밸브를 닫을 수 있도록 하고, 그 플런저는 솔레노이드밸브로의 전원공급이 차단될 때 스프링의 탄성력에 의해 밸브를 열 수 있도록 하며, 솔레노이드밸브를 제어하지 못하여 전기 압력밥솥 겸용 조리기의 내부압력이 허용치 이상으로 상승되면 플런저의 상단에 설치된 밸브캡이 오픈되면서 내부의 증기압력을 배출할 수 있도록 함으로서 달성될 수 있다.The purpose of the present invention is to move the plunger downward with the electromagnet provided in the solenoid valve to close the valve, the plunger to open the valve by the spring force when the power supply to the solenoid valve is cut off, When the internal pressure of the electric pressure cooker combined cooker is increased beyond the allowable value by not controlling the solenoid valve, the valve cap installed at the top of the plunger may be opened to discharge the internal steam pressure.

밥솥용기(12)가 삽입되는 전기 압력밥솥 겸용 조리기 본체(10)에 개폐 가능하게 결합되는 덮개본체(11)에는 밥솥용기(12)의 뚜껑(13)을 고정하면서 덮개본체(11)에 고정된 뚜껑(13)에는 솔레노이드밸브를 고정함에 있어서, 상기 솔레노이드밸브(1)의 중앙에는 스프링(3)의 탄성력을 상측으로 받는 플런저(4)를 설치하고, 그 플런저(4) 외측의 솔레노이드밸브(1)에는 전자석(2)을 구비하여 전자석(2)에 전원이 공급되면 플런저(4)를 하측으로 이동시킬 수 있도록 하며, 상기 플런저(4)의 상단에는 밸브캡(6)을 설치하여 플런저(4)의 통공(5)으로 통하는 증기유로를 개폐할 수 있도록 한다.The cover body 11 is coupled to the cover main body 11 so as to be openable and close to the electric pressure cooker combined cooker body 10 into which the cooker container 12 is inserted, while being fixed to the cover body 11 while fixing the lid 13 of the cooker container 12. In fixing the solenoid valve to the lid 13, the center of the solenoid valve (1) is provided with a plunger (4) receiving the elastic force of the spring (3) upward, the solenoid valve (1) outside the plunger (4) ) Is provided with an electromagnet 2 to move the plunger 4 downward when power is supplied to the electromagnet 2, and a valve cap 6 is installed on the top of the plunger 4 to provide a plunger 4. To open and close the steam flow path through the through hole (5).

이때, 상기 밸브캡(6)은 고온고압의 증기에 노출되어도 변형이 발생되지 않는 실리콘재로 형성하고, 그 밸브캡(6)에는 플랜지(7)를 형성하여 그 플랜지(7)가 증기유로를 직접 개폐할 수 있도록 한다.At this time, the valve cap (6) is formed of a silicone material that does not occur deformation even when exposed to steam at high temperature and high pressure, the valve cap (6) forms a flange (7) so that the flange 7 Open and close directly.

또한, 상기 밸브캡(6)에 형성된 플랜지(7)는 솔레노이드밸브(1)의 제어가 불가능하여 전기 압력밥솥 겸용 조리기 내부에 이상고압이 발생하면 그 압력에 의해 들리면서 안전밸브의 역할을 할 수 있도록 플랜지(7) 상측 밸브캡(6)에 경사면(8)을 형성한다.In addition, the flange (7) formed in the valve cap (6) is not possible to control the solenoid valve (1) when abnormal high pressure occurs inside the electric pressure cooker combined cooker can be heard by the pressure to act as a safety valve. The inclined surface 8 is formed in the valve cap 6 above the flange 7.

이와 같이 구성된 본 발명은 전기 압력밥솥 겸용 조리기 본체(10)내에 취사 또는 조리재료가 담긴 밥솥용기(12)를 삽입하고, 뚜껑(13)이 결합된 덮개본체(11)를 닫은 후 전원을 공급하면 전기 압력밥솥 겸용 조리기 본체(10) 하측의 가열판(14)에서 발생되는 열로 취사 및 조리를 할 수 있는 것이다.When the present invention configured as described above is inserted into the cooker container 12 for cooking or cooking material contained in the cooker body 10 combined with an electric pressure cooker, and the power is supplied after closing the cover body 11 to which the lid 13 is coupled. The cooking and cooking can be performed by the heat generated by the heating plate 14 under the electric pressure cooker combined cooker body 10.

이때, 취사 또는 조리를 할 때는 솔레노이드밸브(1)에 구비된 전자석(2)에 전원이 공급되도록 하면 플런저(4)가 하측으로 이동하면서 솔레노이드밸브(1)를 닫게 된다.At this time, when cooking or cooking, if power is supplied to the electromagnet 2 provided in the solenoid valve 1, the plunger 4 moves downward to close the solenoid valve 1.

즉, 플런저(4)가 하향이동되면 그 플런저(4)의 상단에 설치된 밸브캡(6)의 플랜지(7)가 솔레노이드밸브(1)의 본체에 밀착되므로 솔레노이드밸브(1)의 증기유로를 차단하게 되는 것이다.That is, when the plunger 4 is moved downward, the flange 7 of the valve cap 6 installed at the upper end of the plunger 4 comes into close contact with the main body of the solenoid valve 1, thereby shutting off the steam flow path of the solenoid valve 1. Will be done.

따라서, 취사 또는 조리를 시작하여 밥솥용기(12)내에 솔레노이드밸브(1)의 플런저(4)를 밀어 올릴 수 있는 압력이 형성될 때까지 내부의 압력이 유출되는 것을 방지할 수 있을 뿐만 아니라, 이로 인하여 취사 또는 조리시간을 단축할 수 있는 것이다.Therefore, not only the pressure inside the cooker vessel 12 can be prevented from leaking until the pressure for raising the plunger 4 of the solenoid valve 1 is formed in the cooker container 12, Due to the cooking or cooking time can be shortened.

한편, 상기와 같이 하여 취사 또는 조리를 완료한 후 솔레노이드밸브(1)의 전자석(2)에 공급되던 전원을 차단하면 플런저(4)는 스프링(3)의 탄성력에 의해 상향이동되어 밸브캡(6)과 솔레노이드밸브(1) 본체를 분리시키므로 밥솥용기(12) 내부의 압력이 플런저(4)의 통공(5)와 소음캡(9)을 통해 배출되는 것이다.On the other hand, after completing the cooking or cooking as described above, if the power supplied to the electromagnet 2 of the solenoid valve 1 is cut off, the plunger 4 is moved upward by the elastic force of the spring (3) valve cap (6) ) And the solenoid valve (1) to separate the main body is the pressure inside the cooker container 12 is discharged through the through hole (5) and the noise cap (9) of the plunger (4).

특히, 본 발명에 의한 솔레노이드밸브(1)는 취사 또는 조리를 시작한 이후에 솔레노이드밸브(1)의 제어계통에 이상이 발생되어 솔레노이드밸브(1)를 제어할 수 없는 상황이 되어도 전기 압력밥솥 겸용 조리기의 내부의 압력이 허용치 이상으로 상승되는 것을 방지할 수 있다.In particular, the solenoid valve 1 according to the present invention is an electric pressure cooker combined cooker even when a situation occurs in which the control system of the solenoid valve 1 cannot control the solenoid valve 1 after starting cooking or cooking. It is possible to prevent the pressure inside the valve from rising above the allowable value.

즉, 도 6a 및 도 6b에 도시된 바와 같이 솔레노이드밸브(1)의 제어계통에 발생된 고장 등으로 전기 압력밥솥 겸용 조리기의 내부 압력이 계속상승하면 그 압력은 플런저(4)의 통공(5)을 통해 밸브캡(6)의 플랜지(7)에 작용된다.That is, as shown in FIGS. 6A and 6B, when the internal pressure of the electric pressure cooker combined cooker continuously rises due to a failure occurring in the control system of the solenoid valve 1, the pressure is increased through the opening 5 of the plunger 4. It acts on the flange 7 of the valve cap 6 through.

따라서, 그 플랜지(7)에 작용되는 압력이 플랜지(7)의 설계압력보다 커지면 플랜지(7)는 밸브캡(6)에 형성된 경사면(8)을 향해 꺽이게 되므로 그 사이의 공간으로 내부압력이 배출되어 별도의 동력이나 별도의 안전밸브를 사용하지 않아도 하나의 솔레노이드밸브(1)로 안전밸브를 겸하여 사용할 수 있게 되는 것이다.Therefore, when the pressure applied to the flange 7 is greater than the design pressure of the flange 7, the flange 7 is bent toward the inclined surface 8 formed in the valve cap 6, so that the internal pressure is increased to the space therebetween. Since it is discharged, it is possible to use a safety valve as a solenoid valve 1 without using a separate power or a separate safety valve.

상기에서와 같이 본 발명은 솔레노이드밸브에 구비된 전자석으로 플런저를 하향 이동시켜 밸브를 닫을 수 있도록 하고, 그 플런저는 솔레노이드밸브로의 전원공급이 차단될 때 스프링의 탄성력에 의해 밸브를 열 수 있도록 하며, 솔레노이드밸브를 제어하지 못하여 전기 압력밥솥 겸용 조리기의 내부압력이 허용치 이상으로 상승되면 플런저의 상단에 설치된 밸브캡이 오픈되면서 내부의 증기압력을 배출할 수 있도록 함으로서 전기 압력밥솥 겸용 조리기의 뚜껑을 닫고 취사 및 찜 등의 조리를 할 때 내부의 고압증기가 조리중에 미세하게 배출되는 것을 방지할 수 있고, 조리가 완료되면 내부의 고압증기를 신속하게 배출할 수 있을 뿐만 아니라, 솔레노이드밸브의 제어불능시 플런저의 상단에 설치된 밸브캡이 안전밸브의 역할을 하여 내부의 고압증기를 배출할 수 있는 효과가 제공되는 것이다.As described above, the present invention allows closing the valve by moving the plunger downward to the electromagnet provided in the solenoid valve, the plunger to open the valve by the elastic force of the spring when the power supply to the solenoid valve is cut off If the internal pressure of the electric pressure cooker combined cooker cannot be controlled because the solenoid valve is not controlled, the valve cap installed at the top of the plunger is opened to release the internal steam pressure, thereby closing the lid of the electric cooker combined with the electric pressure cooker. When cooking, cooking or steaming, it is possible to prevent the internal high-pressure steam from being discharged minutely during cooking, and when the cooking is completed, the internal high-pressure steam can be discharged quickly, and when the solenoid valve is out of control The valve cap installed on the upper part of the plunger acts as a safety valve. The effect of releasing the group is provided.
