Description

취사용 압력솥의 증기배출장치{DEVICE FOR DISCHARGING STEAM OF PRESSURE COOKER}DEVICE FOR DISCHARGING STEAM OF PRESSURE COOKER}

본 고안은 취사용 압력솥의 증기배출장치에 관한 것으로, 더욱 상세하게는 하나의 증기흡입구로 유입되는 증기를 솔레노이드밸브와 압력유지밸브 그리고 안전밸브를 이용하여 하나의 배출구로 배출하도록 구성되는 취사용 압력솥의 증기배출장치에 관한 것이다.The present invention relates to a steam discharge device of the cooking pressure cooker, and more particularly, the steam of the cooking pressure cooker configured to discharge the steam flowing into one steam inlet to one outlet by using the solenoid valve, the pressure holding valve and the safety valve. It relates to a discharge device.

일반적으로, 취사용 압력솥은 증기의 압력으로 밥 또는 여러음식을 증숙하는것으로 널리 사용되고 있고, 용기내에 증기압력이 발생된다는 점에서 증기배출장치의 중요성을 고려하여 여러가지 안전장치가 개발되어 있다.In general, cooking pressure cookers are widely used for steaming rice or other foods under the pressure of steam, and various safety devices have been developed in consideration of the importance of the steam discharge device in that steam pressure is generated in a container.

그리고, 종래의 증기배출장치는 솔레노이드밸브와 압력유지밸브 그리고 안전밸브중 어느 하나만을 채택하여 사용하거나 어느 두개를 선택적으로 단순 조합하여 사용하게 된다.In addition, the conventional steam discharge device is used by using only one of the solenoid valve, the pressure holding valve and the safety valve or by using any combination of the two simply.

더욱이, 종래의 증기배출장치는 선택적으로 사용되고 있는 솔레노이드밸브, 압력유지밸브 그리고 안전밸브가 각각 증기흡입구와 증기배출구를 갖도록 설계되어 있다.Moreover, the conventional steam discharge device is designed such that the solenoid valve, the pressure holding valve, and the safety valve, which are selectively used, have steam inlets and steam outlets, respectively.

이처럼, 종래의 증기배출장치는 솔레노이드밸브와 압력유지밸브 그리고 안전밸브중 어느 하나만을 채택하여 사용하거나 어느 두개를 선택적으로 단순 조합하여 사용함으로써 그만큼 부피가 커지거나 부품수가 많아지면서 제조원가를 상승시키게 되고, 안정적인 증기배출이 어려운 문제가 있다.As such, the conventional steam discharge device adopts solenoid valves, pressure holding valves, and safety valves by using only one of them or by selectively using a combination of two, thereby increasing the manufacturing cost by increasing the volume or the number of parts. Stable steam discharge is a difficult problem.

또한, 종래의 증기배출장치는 다수의 증기흡입구와 증기배출구를 갖도록 구성됨으로써 그 구조가 복잡하고 증기배출제어가 어렵다는 단점이 있다.In addition, the conventional steam discharge device has a disadvantage that the structure is complicated and difficult to control the steam discharge by being configured to have a plurality of steam inlet and steam outlet.

본 고안은 이러한 종래의 문제점을 개선하기 위하여 고안된 것으로, 하나의 흡입구로 유입되는 증기를 솔레노이드밸브와 압력유지밸브 그리고 안전밸브를 이용하여 하나의 배출구로 배출하도록 구성됨으로써 안정적인 증기배출을 도모할 수 있을 뿐만 아니라 부품수을 줄이면서 콤팩트화가 가능하고, 그 제조원가를 현저히 절감할 수 있는 취사용 압력솥의 증기배출장치를 제공함에 그 목적이 있다.The present invention is designed to improve such a conventional problem, it is possible to achieve a stable vapor discharge by being configured to discharge the steam flowing into a single inlet to a single outlet using a solenoid valve, a pressure holding valve and a safety valve. In addition, the object of the present invention is to provide a steam discharging device for a cooking pressure cooker capable of compacting while reducing the number of parts and significantly reducing the manufacturing cost.

상기한 목적을 달성하기 위하여 본 고안은 압력용기내의 증기압을 배출하도록 설치되는 취사용 압력솥의 증기배출장치에 있어서, 증기흡입구로 유입되는 압력용기내의 증기압을 제1,2,3밸브시트를 통해 증기배출구로 배출하도록 이루어진 하우징에 통상의 솔레노이드밸브와 압력유지밸브 그리고 안전밸브를 설치하되, 솔레노이드밸브의 오작동에 의한 제1밸브시트의 폐쇄로 이상압력발생시 압력유지밸브와 안전밸브의 포펫을 차례로 후진시켜 제2,3밸브시트를 개방하도록 구성되는 취사용 압력솥의 증기배출장치를 제공하게 된다.In order to achieve the above object, the present invention provides a steam discharging device for a cooking pressure cooker which is installed to discharge steam pressure in a pressure vessel, wherein the steam pressure in the pressure vessel flowing into the steam inlet is controlled through the first, second and third valve seats. The solenoid valve, the pressure holding valve, and the safety valve are installed in the housing configured to discharge the gas, and when the abnormal pressure occurs due to the closing of the first valve seat due to the malfunction of the solenoid valve, It is to provide a steam discharge device for the cooking pressure cooker configured to open the 2,3 valve seat.

이하, 첨부된 도면을 참조하여 본 고안의 바람직한 실시예를 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

도1은 본 고안에 따른 취사용 압력솥의 증기배출장치를 나타내는 단면도이다.1 is a cross-sectional view showing a steam discharge device for the cooking pressure cooker according to the present invention.

본 고안에 따른 취사용 압력솥의 증기배출장치는 하나의 증기흡입구(3)와 증기배출구(7)와, 이를 연결하는 제1,2,3밸브시트(4,5,6)를 형성하는 하우징(1)에 솔레노이드밸브(10)와 안전밸브(20) 그리고 압력유지밸브(30)를 결합하여 제1,2,3밸브시트(4,5,6)를 각각 개폐하도록 구성되어 있다.Steam discharging device for the cooking pressure cooker according to the present invention is a housing (1) forming one steam inlet (3) and steam outlet (7), and the first, second, third valve seat (4, 5, 6) connecting the same ) Is coupled to the solenoid valve 10, the safety valve 20 and the pressure holding valve 30 to open and close the first, second, third valve seat (4, 5, 6), respectively.

따라서, 본 고안에서는 하나의 증기흡입구(3)로 배출되는 압력용기내의 증기압을 솔레노이드밸브(10)와 안전밸브(20) 그리고 압력유지밸브(30)에 의해 제1,2,3밸브시트(4,5,6)를 개폐함으로써 하나의 증기배출구(7)를 통해 외부로 배출하도록 설계되어 있다.Therefore, in the present invention, the first, second, and third valve seats 4 may be formed by the solenoid valve 10, the safety valve 20, and the pressure holding valve 30 by the steam pressure in the pressure vessel discharged to one steam inlet 3. It is designed to discharge to the outside through one steam outlet 7 by opening and closing.

즉, 상시열림형의 솔레노이드밸브(10)는 통상의 마이콤 제어에 따라 코일(12)에 통전이 이루어지면 가동철심(11)에 전자력이 유도되면서 가동철심이 전진하여 고정철심(15)에 부착되고, 이에 따라 스풀(13)의 포펫(14)이 전진이동되어 제1밸브시트(4)를 닫게 된다.That is, the normally open solenoid valve 10 is applied to the coil 12 in accordance with the conventional microcomputer control when the electromagnetic force is induced in the movable iron core 11 while the movable iron core is advanced and attached to the fixed iron core 15 Accordingly, the poppet 14 of the spool 13 is moved forward to close the first valve seat 4.

그리고, 안전밸브(20)는 압축스프링(24)의 탄성력과 노브(21)의 자중이 작용하는 포펫(25)을 이용하여 제3밸브시트(6)를 닫게 되고, 솔레노이드밸브(20)와 압력유지밸브(30)의 오작동으로 압력용기내의 증기압이 위험압력(1.3∼1.7㎏f/㎠)에 근접하게 되면 최종적으로 제3밸브시트를 개방하여 증기압을 배출하도록 설계되어 있다.In addition, the safety valve 20 closes the third valve seat 6 by using the poppet 25 on which the elastic force of the compression spring 24 and the self-weight of the knob 21 act, thereby closing the solenoid valve 20 and the pressure. When the vapor pressure in the pressure vessel approaches the dangerous pressure (1.3 to 1.7 kgf / cm 2) due to the malfunction of the holding valve 30, the third valve seat is finally opened to discharge the vapor pressure.

또한, 압력유지밸브(30)는 솔레노이드밸브(10)의 포펫(14)이 제1밸브시트(4)를 닫고 있는 동안 압축스프링(33)의 탄성력을 이용하여 포펫(32)으로 제2밸브시트(5)를 폐쇄함으로써 압력용기내의 음식증숙을 위한 증기압을 유지시키게 된다.In addition, the pressure holding valve 30 uses the elastic force of the compression spring 33 to the second valve seat while the poppet 14 of the solenoid valve 10 is closing the first valve seat 4. By closing (5), the steam pressure for steaming food in the pressure vessel is maintained.

다시 말하면, 솔레노이드밸브(10)와 압력유지밸브(30)에 의해 제1,2밸브시트(4,5)가 각각 닫히면서 증기흡입구(3)를 통해 유입된 증기압의 배출이 차단되고, 압력용기내의 증기압이 일정압력(0.9㎏f/㎠)을 유지하면서 압력용기내의 음식이 증숙 조리된다.In other words, the first and second valve seats 4 and 5 are closed by the solenoid valve 10 and the pressure holding valve 30, respectively, and the discharge of the steam pressure introduced through the steam inlet 3 is blocked, and the pressure vessel is closed. The food in the pressure vessel is steamed and cooked while the vapor pressure in the container maintains a constant pressure (0.9 kgf / cm 2).

여기서, 압력솥의 압력용기내에서 음식의 조리가 완료되면 코일(12)의 통전를 차단하게 되고, 이로써 가동철심(11)에 유도되어 있던 전자력이 제거되면서 증기압에 의해 스풀(13)의 포펫(14)이 후진되어 제1밸브시트(4)를 개방하게 된다.Here, when cooking of the food is completed in the pressure vessel of the pressure cooker, the energization of the coil 12 is cut off, thereby eliminating the electromagnetic force induced in the movable iron core 11, thereby removing the poppet 14 of the spool 13 by the steam pressure. This reverse is to open the first valve seat (4).

그러나, 여러가지 원인에 의해 마이컴이 오작동되면서 코일(4)에 계속적으로 통전될 경우 가동철심(11)에 전자력이 유도되면서 스풀(13)의 포펫(14)에 의한 제1밸브시트(4)의 닫힘이 유지되거나 포펫(14)이 제1밸브시트(4)에 고착되면서 밸브시트의 닫힘상태가 유지되는 경우, 증기배출구(7)를 통한 증기배출이 이루어지지 않게 되면 압력용기내의 증기압이 계속 증가하게 되지만 위험압력(1.3∼1.7㎏f/㎠)에 이르기 전에 증기압에 의해 압축스프링(33)의 탄성력을 극복하고 포펫(32)이 후진되면서 제2밸브시트(5)가 개방된다.However, when the microcomputer malfunctions due to various causes and the coil 4 is continuously energized, electromagnetic force is induced to the movable core 11 and the first valve seat 4 is closed by the poppet 14 of the spool 13. If the valve seat is maintained or the poppet 14 is fixed to the first valve seat 4 and the valve seat is kept closed, the steam pressure in the pressure vessel is continuously increased when the vapor discharge through the steam outlet 7 is not performed. However, before reaching the dangerous pressure (1.3 to 1.7 kgf / cm 2), the second valve seat 5 is opened while the elastic force of the compression spring 33 is overcome by the vapor pressure and the poppet 32 is retracted.

따라서, 상시닫힘형의 압력유지밸브(30)에 의해 제2밸브시트(5)가 개방되면서 압력용기내의 증기가 증기배출구(7)를 통해 외부로 배출되어 압력솥의 폭발이라는 사고를 1차적으로 방지하게 된다.Therefore, while the second valve seat 5 is opened by the normally closed pressure holding valve 30, steam in the pressure vessel is discharged to the outside through the steam outlet 7 to prevent an accident of explosion of the pressure cooker. Done.

그러나, 솔레노이드밸브(20)와 압력유지밸브(30)의 오작동으로 압력용기내의 증기압이 위험압력(1.3∼1.7㎏f/㎠)에 근접하게 되면 안전밸브(20)의 포펫(25)이 후진되면서 최종적으로 제3밸브시트(6)를 개방하여 증기압을 배출하게 된다.However, when the steam pressure in the pressure vessel approaches the dangerous pressure (1.3 to 1.7 kgf / cm 2) due to a malfunction of the solenoid valve 20 and the pressure holding valve 30, the poppet 25 of the safety valve 20 is reversed. Finally, the third valve seat 6 is opened to discharge steam pressure.

본 고안은 하나의 증기흡입구로 유입되는 증기를 솔레노이드밸브와 압력유지밸브 그리고 안전밸브를 이용하여 하나의 증기배출구로 배출하도록 구성됨으로써 안정적인 증기배출을 도모할 수 있을 뿐만 아니라 부품수을 줄이면서 콤팩트화가 가능하고, 그 제조원가를 현저히 절감할 수 있는 효과를 제공하게 된다.The present invention is configured to discharge steam flowing into one steam inlet to one steam outlet by using solenoid valve, pressure holding valve and safety valve, which not only enables stable steam discharge but also enables compactization while reducing the number of parts. In addition, it provides an effect that can significantly reduce the manufacturing cost.
