Abstract

본 고안은 전기압력밥솥에 있어서 압력배출용 솔레노이드밸브에 관한 것이며, 전기압력밥솥에서 전기적인 동작으로 솔레노이드의 자기력으로 플런져가 동작되면서 밸브의 개폐가 이루어지도록 한 것이다.The present invention relates to a pressure discharge solenoid valve in an electric pressure cooker, and to open and close the valve while the plunger is operated by the magnetic force of the solenoid by the electrical operation in the electric pressure cooker.

종래에는 전기압력밥솥에서 음식을 조리할때 밥솥내부의 압력이 스프링의 압력과 밸브중량보다 커지면 압력이 배출될수 있도록 구성하게 되나, 이는 조리음식에 따라 압력의 가변조정이 불가능하고, 사용기간이 경료됨에 따라 수분과 녹말분이 끼어져 밸브의 기능이 저하되고, 산화, 부식으로 인하여 장구히 사용되지 못하였다.Conventionally, when food is cooked in an electric pressure cooker, the pressure inside the cooker is configured to be discharged when the pressure of the spring is greater than the pressure of the spring and the valve weight, but it is impossible to adjust the pressure according to the cooked food, and the use period is light. As water and starch were trapped, the function of the valve was reduced, and it was not used for long due to oxidation and corrosion.

또 솔레노이드를 증기배출부재에 연결하여 솔레노이드의 동작에 따라 밥솥내부의 고온고압의 증기가 배출되도록 하는 구성이 있으나, 이는 조리되는 음식에 따라 배출되는 압력을 가변시킬 수 있는 잇점은 있으나, 증기가 배출되면서 수분과 녹말분이 솔레노이드를 구성하는 밸브, 플런져등에 틈입되거나 접촉으로 인하여 산화, 부식이 심하고, 또 사용기간이 경료됨에 따라 전자력이 떨어지고 기능과 내구성이 저하되어 장구히 사용되지 못하였다.In addition, there is a configuration in which the high temperature and high pressure steam in the rice cooker is discharged according to the operation of the solenoid by connecting the solenoid to the steam discharge member, but this has the advantage of varying the pressure discharged according to the cooked food, but the steam is discharged. As the water and starch are in contact with the valves, plungers, etc. that make up the solenoid, the oxidation and corrosion are severe due to contact with each other.

이에 본고안은 종래의 각종 제반결점을 해소한 것으로 솔레노이드와 증기배출구사이에 위치되는 밸브에 연질의 합성고무재로 된 다이아후레임으로 구획하여 솔레노이드에 고온고압의 증기와의 접촉을 해소하고, 고온고압의 증기를 코일외곽으로 분출시킬 수 있도록 하여 증기의배출을 안정화하고, 효과적으로 배출하여 솔레노이드내부의 산화, 부식을 해소하고 오작동이 없이 장구히 사용할 수 있도록 한 고안이다.In this regard, this paper solves various conventional defects. The valve is located between the solenoid and the steam outlet and divided into a diaphragm made of soft synthetic rubber to eliminate contact with the steam at high temperature and high pressure. It is designed to stabilize the discharge of steam by discharging the steam out of the coil and effectively discharge it to eliminate oxidation and corrosion inside the solenoid and to use it for a long time without malfunction.

본고안은 전기압력밥솥에 있어서 압력배출용 솔레노이드밸브에 관한 것이며, 전기압력밥솥에서 전기적동작으로 솔레노이드의 자기력으로 플런져가 동작되어져 밸브의 개폐가 이루어지도록 한 것이다.The present invention relates to a pressure discharge solenoid valve in an electric pressure cooker, and the plunger is operated by the magnetic force of the solenoid by the electrical operation in the electric pressure cooker to open and close the valve.

종래에는 전기압력밥솥의 뚜껑에 중량추로 된 밸브와 스프링으로 지지하여 음식물을 조리할 때 밥솥내부가 고온고압으로 변화되면서 밸브의 중량과 스프링의 압력보다 커지게 되면 밸브가 열려져 고온고압의 증기가 분출되도록 하는 구성이 있으나, 이는 조리하는 음식에 따라 압력의 가변조종이 불가능하고, 특히 사용기간이 경료됨에 따라 음식물의 조리과정에서 발생되는 증기가 분출되었다가 냉각되면서 증기의 분출통로와 밸브에 녹말분이 굳어져 밸브의 기능이 저하되고, 또 산화, 부식이 발생되어 장구히 사용되지 못하는 결점이 있었다.Conventionally, when cooking food by supporting the valve and spring made of weight on the lid of the electric pressure cooker, when the inside of the cooker is changed to high temperature and high pressure, the valve opens when the weight of the valve becomes greater than the pressure of the spring and the high temperature and high pressure steam. Although there is a configuration to eject, it is impossible to control the pressure depending on the food to be cooked, in particular, as the period of use is reduced, the steam generated during the cooking process of the food is ejected and cooled, and starch in the steam outlet passage and valve The powder had hardened and the function of the valve deteriorated, and oxidation and corrosion occurred, and there was a defect that it could not be used for a long time.

이를 개량한 선행기술로는 압력밥솥의 뚜껑지점에 구성되는 밸브의 상부에 코아와 밸브로 구성되는 솔레노이드를 구성하여 솔레노이드의 동작에 따라 밸브가 동작하여 압력밥솥의 고온고압의 증기를 증기배출부재를 통하여 외부로 분출될 수 있도록 하는 구성과, 솔레노이드밸브가 동작되면 밸브가 상승되어져 고온고압의 증기가 밸브외곽을 통하여 수직으로 분출되는 구성으로 사용되고 있다.In order to improve the prior art, a solenoid composed of a core and a valve is formed on the upper portion of the valve configured at the lid of the pressure cooker, and the valve operates according to the operation of the solenoid to produce steam of the high temperature and high pressure of the pressure cooker. It is used to the configuration that allows to be ejected to the outside through, and the valve is raised when the solenoid valve is operated so that the high-temperature, high-pressure steam is ejected vertically through the valve outside.

위와같이 솔레노이드를 이용하여 밥솥내부의 고온고압의 증기를 분출시키는 구성은 밥솥에서 조리되는 음식물에 따라 밥솥내부의 압력을 조정하여 조리할 수 있는 잇점은 있으나, 고압증기가 분출되면서 조리되는 음식의 녹말분과 수분이 밸브봉과 솔레노이드를 구성하는 코아 및 플런져등에 접촉되면서 사용기간이 경과됨에 따라 녹말분이 끼어 오작동의 원인이 되거나, 또는 수분과의 접촉으로 산화와 부식의 요인이 되고,또 전자력이 떨어져 기능과 내구성이 저하되어 장구히 사용되지 못하게 되므로 별도의 안전장치로 압력을 배출시킬 수 있는 부재가 요구되는 폐단이 있어왔다.Using the solenoid as described above to eject the high temperature and high pressure steam in the rice cooker has the advantage that can be cooked by adjusting the pressure in the rice cooker according to the food cooked in the rice cooker, but starch of the food that is cooked when the high pressure steam is ejected As powder and moisture come into contact with the cores and plungers that make up the valve rod and solenoid, the starch powder gets stuck as a result of the period of use, or it causes oxidation and corrosion due to contact with moisture. Since the endurance and the durability is reduced so that it can not be used for a long time, there has been a need for a member that can release pressure as a separate safety device.

이에 본 고안은 솔레노이드와 고온고압의 증기를 배출시키는 통로사이에 연질의 합성고무재로 된 다이아후레임을 구성하여 솔레노이드와 증기배출통로간을 구획시켜 밸브가 개폐되면서 고온고압의 증기로 인한 산화와 부식을 방지하고, 오작동을 해소시킬 수 있는 솔레노이드밸브를 제공함에 목적이 있다.Therefore, the present invention composes a diaphragm made of soft synthetic rubber material between the solenoid and the passage for discharging high temperature and high pressure steam, and divides the solenoid and the steam discharge passage so that the valve is opened and closed. It is an object of the present invention to provide a solenoid valve that can prevent the damage and eliminate the malfunction.

도면중 미설명부호 20은 밥솥뚜껑, 21은 증기배출캡, 22는 체결나사를 표시한 것이다.In the figure, reference numeral 20 denotes a rice cooker lid, 21 denotes a steam discharge cap, and 22 denotes a fastening screw.

이와같이 구성된 본고안의 작용효과를 설명하면 다음과 같다.The operational effects of the proposed paper thus constructed are as follows.

몸통베이스(1)위로 증기배출판(2), 다이후레임(3), 와셔판(4)을 위치시키며, 그위로는 플런져(6)와 스프링(7), 코아(8)를 차례로 내장시킨 코일(5)과 윗판(9)을 차례로 적층시켜서 외피(10)를 씌워 외피(10) 하연을 걸림돌부(10a)가 형성되도록 몸통베이스(1)하방 걸림턱(1c)에서 감합시켜 한몸통으로 된 솔레노이드밸브를 구성하게 되면 압력밥솥에서 고온고압의 증기를 배출시키는 솔레노이드밸브가 구성된다.A steam discharge plate (2), a die frame (3), and a washer plate (4) are positioned on the body base (1), and the plunger (6), the spring (7), and the core (8) are sequentially installed thereon. The coil 5 and the upper plate 9 are sequentially stacked to cover the outer shell 10 so that the lower edge of the outer shell 10 is fitted at the lower locking jaw 1c so that the locking protrusion 10a is formed. When the solenoid valve is configured, the solenoid valve is configured to discharge steam of high temperature and high pressure from the pressure cooker.

이와같은 솔레노이드밸브를 통상 전기압력밥솥을 구성하는 밥솥뚜껑(20)의 일단에 몸통베이스(1)의 하방을 끼워서 체결나사(22)로 체결하고, 윗판(9)의 증기배출관(9b)에 증기배출캡(21)을 결합하여 사용하게 되는데, 이와같은 솔레노이드밸브의 동작과정을 설명하면 즉 전기압력밥솥에서 조리하는 음식물의 종류에 따라서 증기압을 제어하는 IC회로에 설정하거나 또는 전기회로에 시간조절타이머를 연결하여 밸브의 동작시점을 설정하여 전원을 연결시키면 코일(5)에 전기가 통전되면서 코일(5)의 삽지구(5a)저부에 위치되는 코아(8)의 전자력으로 플런져(6)를 당기게 되어 플런져(6)가 하강되면서 플런져(6)의 로드지지구(6b)에 지지된 로드(3b)가 하강되고, 동 로드(3b)의 하강으로 로드(3b)하단의 밸브(3c)가 하강되어져 몸통베이스(1)중앙의 증기배출구(1a)상연의 돌환부(1a)를 차단하게 된다. 이때 돌환부(1b)에 위치되는 밸브(3c)는 연질의 합성고무재로 씌워져 밀봉상태를 유지하게 된다.The solenoid valve is fastened with a fastening screw 22 by inserting the lower portion of the body base 1 into one end of the cooker lid 20 constituting the electric pressure cooker, and steaming the steam discharge pipe 9b of the upper plate 9. When the discharge cap 21 is used in combination, the operation of the solenoid valve will be described. That is, according to the type of food cooked in the electric pressure cooker, it is set in the IC circuit that controls the steam pressure or the time control timer in the electric circuit. Connect the power by setting the operation point of the valve by connecting the power supply to the coil 5 while the electric power is supplied to the coil 5 so that the plunger 6 is driven by the electromagnetic force of the core 8 located at the bottom of the insertion hole 5a of the coil 5. As the plunger 6 is pulled down, the rod 3b supported by the rod support 6b of the plunger 6 is lowered, and the valve 3c at the bottom of the rod 3b is lowered by the lowering of the rod 3b. ) Is lowered and the base of the trunk base (1) It blocks the projection 1a. At this time, the valve 3c positioned in the projection 1b is covered with a soft synthetic rubber material to maintain a sealed state.

이와같이 전기압력밥솥은 밀봉상태에서 음식이 조리되면서 설정된 압력에 도달되거나 또는 설정된 시간이 경료되면 코아(5)에 전원이 끊어지게 되면서 코아(8)와 플런져(6)사이에서 압축된 스프링(7)의 탄력으로 플런져(6)를 위로 밀어올리게 되면서 고온고압의 증기가 밸브(3c)를 함께 밀어올려 열려지면서 다이아후레임(3)의 유동판(3a)은 와셔판(4)으로 상승되어져 그하방과 증기배출구(1a)의 상면 돌환부(1b)외곽의 요입면(2b)사이에 고온고압의 증기유치공간이 형성되어져 고온고압의 증기는 유치공간에 유치되었다가 증기배출판(2)의 저면과, 외측의 증기배출로(2a) 및 다아이후레임(3)의 증기배출공(3d), 와셔판(4)의 증기배출공(4a), 코일(5)외곽의 증기통로(5c)를 거쳐 상승되어져 윗판(9)의 증기통로(9a)를 통하여 중앙의 증기배출관(9b)으로 모아져 증기배출캡(21)의 증기배출구를 통하여 외부로 배출되어지게 된다.In this way, the electric pressure cooker is a spring (7) compressed between the core (8) and the plunger (6) while the food is cooked in a sealed state when the set pressure is reached or when the set time passes, the power is cut off to the core (5). As the plunger 6 is pushed upward by the elasticity of the steam, the high temperature and high pressure steam is pushed open by pushing the valve 3c together, and the fluid plate 3a of the diaphragm 3 is raised to the washer plate 4 The high temperature and high pressure steam holding space is formed between the lower side and the recessed surface 2b outside the upper projection 1b of the steam outlet 1a so that the high temperature and high pressure steam is held in the holding space, The bottom surface, the outer steam exhaust passage 2a and the steam exhaust hole 3d of the die frame 3, the steam exhaust hole 4a of the washer plate 4, and the steam passage 5c outside the coil 5 Through the steam passage (9a) of the upper plate (9) is collected to the central steam discharge pipe (9b) to discharge steam It becomes the vapor through the outlet (21) discharging to the outside.

이때 전기압력밥솥에서 배출되는 고온고압의 증기가 몸통베이스(1)의 증기배출구(1a)상연의 돌환부(1b)를 통하여 배출되면서 다이아후레임(3)의 유동판(3a)에서 구획되어진 상태에서 증기가 배출되므로 배출되는 증기에 함유된 수분이나 녹말분등은 코일(5)이나 플런져(6), 스프링(7), 코아(8)에는 전혀 접촉이 이루어지지 않게 되므로서 사용기간이 경과되더라도 산화부식 또는 오작동의 요인이 모두 해소된다.At this time, while the high temperature and high pressure steam discharged from the electric pressure cooker is discharged through the protrusion 1b on the steam outlet 1a of the trunk base 1, it is partitioned from the fluid plate 3a of the diaphragm 3. Since the steam is discharged, the moisture or starch powder contained in the discharged steam does not come into contact with the coil 5, the plunger 6, the spring 7, or the core 8 at all. All causes of oxidative corrosion or malfunction are eliminated.

또 밸브(3c)의 외곽에는 유동판(3a)이 구성되는 다이아후레임(3)이 사용되므로 동 유동판(3a)은 배출되는 증기압에 따라 변화되므로 증기의 분출은 안정시키게 된다.In addition, since the diaphragm 3 including the flow plate 3a is used on the outer side of the valve 3c, the flow plate 3a is changed according to the discharged steam pressure, so that the steam is stabilized.

이와같이 본고안은 압력밥솥에서 증기의 배출에 사용되는 솔레노이드 밸브를 구성할 때 연질의 합성고무재로 다이아후레임을 구성하여 솔레노이드와 증기배출통로간을 구획시켜 배출되는 고온고압의 증기가 솔레노이드밸브에 접촉되지 않게 하므로서 산화와 부식을 방지하고 오작동을 해소하여 솔레노이드밸브를 장구히 사용할 수 있는 매우 실용적이고도 유용한 고안이다.In this way, when constructing the solenoid valve used for the discharge of steam from the pressure cooker, the high temperature and high pressure steam discharged by dividing the solenoid and the steam discharge passage by contacting the solenoid valve is composed of a diaphragm made of soft synthetic rubber material. It is a very practical and useful design that can use the solenoid valve for a long time by preventing oxidation and corrosion and eliminating malfunctions by preventing it from being prevented.
