Description

취사압력솥의 압력유지용 밸브{VALVE FOR MAINTAINING PRESSURE OF PRESSURE COOKER}VALVE FOR MAINTAINING PRESSURE OF PRESSURE COOKER}

본 발명은 취사압력솥의 압력유지용 밸브에 관한 것으로서, 더욱 상세하게는 포펫의 원추형 압력보상부재를 이용하여 밸브시트를 개폐함으로써 압력용기내의 증기배출을 자동 조절하게 되고, 노브를 이용하여 포펫을 수동 조작함으로써 압력용기내의 잔류압력을 외부로 배출할 수 있도록 한 취사압력솥의 압력유지용 밸브에 관한 것이다.The present invention relates to a pressure holding valve of the cooking pressure cooker, and more particularly, by automatically opening and closing the valve seat using the conical pressure compensating member of the poppet to automatically control the steam discharge in the pressure vessel, using the knob to manually The present invention relates to a pressure holding valve of a cooking pressure cooker capable of discharging the residual pressure in the pressure vessel to the outside by operating.

일반적으로, 취사용 압력솥은 증기의 압력으로 밥 또는 여러 음식을 증숙하는 것으로 널리 사용되고 있고, 용기내에 증기압력이 발생된다는 점에서 증기배출장치의 중요성을 고려하여 여러가지 안전장치가 장착되어 있다.In general, cooking pressure cookers are widely used to steam rice or various foods under the pressure of steam, and various safety devices are installed in consideration of the importance of the steam discharge device in that steam pressure is generated in the container.

특히, 도1에 도시한 바와 같이 마이콤의 제어에 따라 코일(4)에 통전이 이루어지면 가동철심(6)에 전자력이 유도되면서 가동철심이 전진하여 고정철심(41)에 부착되고, 이에 따라 스풀(62)의 포펫(12)이 전진이동되어 밸브시트(11-1)를 닫게 된다.In particular, as shown in FIG. 1, when energization is made to the coil 4 under the control of the microcomputer, the movable iron core is advanced while being guided to the movable iron core 6 and is attached to the fixed iron core 41. Poppet 12 of 62 is moved forward to close valve seat 11-1.

이때, 솔레노이드밸브(20)와 압력유지용 밸브(30)에 의해 밸브시트(11-1,11-2)가 각각 닫히면서 증기배출유로(10)를 통한 증기의 배출이 차단되고, 일정압력(0.9㎏f/㎠)을 유지하면서 압력용기내의 음식이 증숙 조리된다.At this time, the valve seats 11-1 and 11-2 are closed by the solenoid valve 20 and the pressure maintaining valve 30, respectively, and the discharge of the steam through the steam discharge passage 10 is blocked, and a constant pressure ( The food in the pressure vessel is steamed and cooked while maintaining 0.9 kgf / cm 2).

여기서, 압력솥의 압력용기내에서 음식의 조리가 완료되면 코일(4)의 전류를 차단하게 되고, 이로써 가동철심(6)에 유도되어 있던 전자력이 제거되면서 증기압에 의해 스풀(62)의 포펫(12)이 후진되어 밸브시트(11-1)를 개방하게 된다.Here, when cooking of the food is completed in the pressure vessel of the pressure cooker, the current of the coil 4 is cut off, thereby removing the electromagnetic force induced in the movable core 6, thereby allowing the poppet 12 of the spool 62 to be steamed. ) Is reversed to open the valve seat 11-1.

그러나, 여러가지 원인에 의해 마이컴이 오작동되면서 코일(4)에 계속적으로 통전될 경우 가동철심(6)에 전자력이 유도되면서 스풀(62)의 포펫(12)에 의한 밸브시트(11-1)의 닫힘이 유지되거나 포펫(12)이 밸브시트(11-1)에 고착되면서 밸브시트의 닫힘상태가 유지되는 경우, 증기배출유로(10-1)를 통한 증기배출이 이루어지지 않게 되면 압력용기내의 증기압이 계속 증가하게 되지만 위험압력(1.3∼1.7㎏f/㎠)에 이르기 전에 증기압에 의해 압축스프링(27)의 탄성력을 극복하고 포펫(25)이 후진되면서 밸브시트(11-2)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 iron core 6 and the valve seat 11-1 is closed by the poppet 12 of the spool 62. If this is maintained or the poppet 12 is fixed to the valve seat 11-1 and the valve seat is kept closed, the steam pressure in the pressure vessel is reduced when steam is not discharged through the steam discharge passage 10-1. Although it continues to increase, the valve seat 11-2 is opened while the poppet 25 is reversed by overcoming the elastic force of the compression spring 27 by the vapor pressure before reaching the dangerous pressure (1.3 to 1.7 kgf / cm 2).

따라서, 상시닫힘형의 압력유지용 밸브(30)에 의해 밸브시트(11-2)가 개방되면서 압력용기내의 증기가 증기배출유로(10)를 통해 외부로 배출되어 압력솥의 폭발이라는 사고를 미연에 방지하게 된다.Therefore, while the valve seat 11-2 is opened by the normally closed pressure holding valve 30, the steam in the pressure vessel is discharged to the outside through the steam discharge passage 10, thus preventing the explosion of the pressure cooker. Will be prevented.

그러나, 종래의 압력유지용 밸브(30)는 압력용기내의 증기압력에 따라 포펫(25)이 밸브시트(11-2)를 반복적이면서 순간적으로 개폐하게 되어 소음을 유발시키게 되고, 일시적인 압력배출로 인해 압력손실이 발생되면서 음식증숙에 필요한에너지를 낭비하게 된다.However, in the conventional pressure holding valve 30, the poppet 25 repeatedly opens and closes the valve seat 11-2 instantaneously and instantaneously according to the steam pressure in the pressure vessel, causing noise, and due to the temporary pressure discharge. The pressure loss creates a waste of energy for food steaming.

더욱이, 음식증숙이 완료되면 압력용기내의 잔류압력을 외부로 배출하여야 하는데, 이때 마이컴의 오작동이나 포펫(12)의 고착에 의해 밸브시트(11-1)의 닫힘상태가 유지되는 경우에도 압력유지용 밸브(30)는 설정압력이하의 잔류압력을 배출할 수 없는 구조적인 문제가 있어 별도의 잔류압력배출장치를 설치하여야 하는 등의 문제가 있다.In addition, when food steaming is completed, the residual pressure in the pressure vessel should be discharged to the outside. In this case, the pressure is maintained even when the valve seat 11-1 is kept closed due to a malfunction of the microcomputer or the sticking of the poppet 12. The valve 30 has a structural problem that cannot discharge the residual pressure below the set pressure, there is a problem such as the need to install a separate residual pressure discharge device.

본 발명은 이러한 종래의 문제점을 개선하기 위하여 안출된 것으로, 포펫의 원추형 압력보상부재를 이용하여 밸브시트의 개폐량을 조절함으로써 압력용기내의 증기압력을 설정한 압력으로 안정적인 유지가 가능하고, 노브를 이용하여 포펫을 수동 조작함으로써 압력용기내의 잔류압력을 외부로 배출할 수 있도록 구성되는 취사압력솥의 압력유지용 밸브를 제공함에 그 목적이 있다.The present invention has been made to improve such a conventional problem, by using the conical pressure compensation member of the poppet by adjusting the opening and closing amount of the valve seat it is possible to maintain a stable at the pressure set the steam pressure in the pressure vessel, the knob It is an object of the present invention to provide a pressure maintaining valve of the cooking pressure cooker configured to discharge the residual pressure in the pressure vessel to the outside by manual operation of the poppet.
