본 고안은 전기를 에너지원으로 작동되는 전기보온압력밥솥에서 전기적인 제어에 의하여 밥솥의 증기를 배출토록한 밥솥의 증기배출장치에 관한 것으로, 더욱 자세하게는, 전기적인 신호에 따라 구동하는 솔레노이드(전자석)의 기본구성인 코일이 권취된 고정철심과 전원의 단속에 의하여 요동하는 플란자의 구조를 이용하여 밥솥의 증기배출을 제어할수 있게된 것이다.The present invention relates to a steam discharge device of the rice cooker to discharge the steam of the rice cooker by electrical control in the electric thermal pressure cooker operated as an energy source, more specifically, a solenoid driven in accordance with the electrical signal (electromagnet It is possible to control the steam discharge of the rice cooker by using the structure of the flannel which is shaken by the fixed iron core wound around the coil, which is the basic configuration of the power supply and the interruption of power.

종래의 경우 전기압력밥솥에서 증기배출 제어를 위한 장치로서는 증기배출통로가 독립적으로 구비되고 해당증기배출통로에 대하여 솔레노이드의 플란자가 통로를 개폐할수 있도록 부가장치한 형태의 것이 소개되고 있으나 구조적으로 증기배출통로를 갖추기 위한 부품과 해당부품에 솔레노이드를 장착하기 위한 구조적인 복잡성이 있고, 또, 해당장치를 구축하는데는 많은 설치공간이 요구됨에 따라 전기압력밥솥의 소형화를 꾀하는데 한계가 있었다.Conventionally, as an apparatus for controlling steam discharge in an electric pressure cooker, a steam discharge passage is independently provided and an additional device is introduced so that the flannel of the solenoid can open and close the passage with respect to the corresponding steam discharge passage. There are limitations in miniaturizing the electric pressure cooker due to the structural complexity of mounting the solenoid to the parts and the parts to provide the discharge passage, and the installation of the device requires a lot of installation space.

그리고, 종래의 솔레노이드에 의해 제어되는 증기배출장치는 단순히 전기적인 신호에 의해서만 증기배출통로에 대해 개방 또는 폐쇄동작을 이행하므로서 밥솥내부용기의 압력정도에 무관하게 작동하게 되므로 위험스런 정도의 고압력상황에 대처능력이 없었기 때문에 별도의 안전증기배출장치(무게추형태)를 장착하여 사용하고 있는 결점이 있었다.In addition, the conventional steam discharge device controlled by the solenoid is operated regardless of the pressure level of the inner vessel of the cooker by performing the opening or closing operation of the steam discharge passage only by an electric signal, thereby coping with a dangerous high pressure situation. Because of its inability, there was a drawback of using a separate safety vapor discharge device (weight weight type).

따라서, 본고안은 상기와 같은 종래의 증기배출장치에서 문제점으로 대두되는 결점을 해소시키고자 개발된 것으로서, 솔레노이드의 기본구성인 고정철심에 증기통로를 구비하고 플란자로 하여금 증기통로의 인입구측을 개폐토록함과, 아울러 상기 플란자는 코일에서 유도되는 기전력과 별도의 탄성부재에 의해 작동되도록 된것으로 솔레노이드 기본구성을 최대활용하여 전기적인 단속에 의해 증기 배출을 제어토록하는 기능수행과, 정도이상의 압력이 작용될경우 증기배출이 이행될수 있는 안전증기배출기능을 하나의 장치로 가능하게 하여 제품의 소형화, 기능의 신뢰성증대를 목적으로 개발된 것이다.Therefore, the present proposal was developed to solve the drawbacks of the conventional steam discharge device as described above. The steam passage is provided on the fixed iron core, which is the basic configuration of the solenoid, and the flanza has the inlet side of the steam passage. In addition to the opening and closing, the flanza is to be operated by the electromotive force induced by the coil and a separate elastic member to perform the function of controlling the steam discharge by electrical interruption by utilizing the basic configuration of the solenoid to the maximum, It was developed for the purpose of minimizing the product and increasing the reliability of the function by enabling the safe steam discharge function to be a single device that can perform steam discharge when pressure is applied.

이하, 상기 기술목적을 달성하기 위한 바람직한 실시예를 도시한 첨부도면에 따라 그 구성 및 작용효과를 상세히 설명하기로 한다.Hereinafter, the configuration and operation effects according to the accompanying drawings showing a preferred embodiment for achieving the technical purpose will be described in detail.

조리대상물을 장입하는 내부용기(10)에 대해 밥솥뚜껑(20)의 내부뚜껑(21)이 덮여 조리실(S)을 제공하는 밥솥에서, 조리실(S)의 증기압력을 솔레노이드(30)로 하여금 증기배출제어토록 이루어진 통상의 증기배출장치에 있어서, 상기 솔레노이드(30)에서 코일(31)의 기전력이 작용되는 고정철심(32) 하단에 요동영역(P)을 형성시켜 플란자(33)에 대해 탄성부재(1) 사이에두고 탄력적으로 조합하되 상기 고정철심(32)과 플란자(33)에는 증기통로(32a)(33a)를 형성시켜 연통되게 조립하였고, 상기 고정철심(32)의 하단은 내부뚜껑(21)에 관통 조립하여 조리실(S)에 노출된 상태로 통공(2a)이 형성된 체결부재(2)로 조립하여 플란자(33)의 선단부(33b)가 통공(2a)에 일치토록함과, 고정철심(32)의 상단은 통공(3a)이 형성된 결착부재(3)로 뚜껑외부체(22)와 체결 조립하여 증기통로(32a)와 통공(3a)이 일치토록 조립하여 구성된 것이다.In the rice cooker providing the cooking chamber S by covering the inner lid 21 of the rice cooker lid 20 with respect to the inner container 10 for charging the cooking object, the steam pressure of the cooking chamber S causes the solenoid 30 to steam. In the conventional vapor discharge device configured to control the discharge, the solenoid 30 is elastic to the planar 33 by forming a rocking region (P) in the lower end of the fixed iron core 32 is applied to the electromotive force of the coil 31 Resilient combinations between the members (1), but the fixed iron core 32 and the planar 33 to form a vapor passage (32a, 33a) to communicate with each other, the lower end of the fixed iron core 32 Assembled through the lid 21 and assembled into the fastening member 2 with the through hole 2a formed in the state exposed to the cooking chamber S so that the tip portion 33b of the planar 33 coincides with the through hole 2a. And, the upper end of the fixed iron core 32 is a binding member 3 formed with a through hole (3a) is fastened and assembled with the lid outer body 22 to the steam passage (32a) Through-hole (3a) is configured to assemble ever match.

상기와 같이 구성되어진 본 고안의 작용효과를 상세히 설명하기로 한다.It will be described in detail the effect of the present invention is configured as described above.

도면 제1도는 본 고안의 주요부분품의 구조 및 그들의 조립순서 관계를 보여주는 분해사시도이고, 제2도는 본 고안이 적용된 전기보온압력밥솥의 조립단면구조도이며, 제3도는 본 고안의 주요부 작동관계를 보여주는 조립단면작동도이다.Figure 1 is an exploded perspective view showing the structure of the main parts of the present invention and their assembly order relationship, Figure 2 is an assembly cross-sectional view of the electric heat pressure cooker to which the present invention is applied, Figure 3 shows the operation of the main part of the present invention Assembly section operation diagram.

도면 제2도에서 30a는 코일케이스이고, 30b는 솔레노이드를 장착하는 지지부재인 것이다.In FIG. 2, 30a is a coil case and 30b is a support member for mounting a solenoid.

전기보온압력밥솥에 본 고안이 적용된 상태에서 소정의 조리대상물에 대한 조리하고자하는 메뉴에 따라 설정된 프로그램에 의한 명령에 따라 솔레노이드(30)에 전원이 단전된 상태에서는 탄성부재(1)의 복원력에 의하여 플란자(33)의 선단부(33b)가 조리실(S)에 노출되어 있는 체결부재(2)의 통공(2a)을 폐쇄상태를 도면 제3도의 a에 도시된 바와같이 유지하게된다.In the state where the present invention is applied to the electric thermal pressure cooker according to the command by the program set according to the menu to be cooked for a predetermined cooking object in the state that the power to the solenoid 30 is cut off by the restoring force of the elastic member (1) The front end portion 33b of the planar 33 maintains the closed state of the through hole 2a of the fastening member 2 exposed to the cooking chamber S as shown in a of FIG. 3.

상기에서와 같이 탄성부재(1)의 복원력으로 플란자(33)로 하여금 통공(2a)을 폐쇄한 상태에서 내부용기(10)의 조리실(S) 압력이 안전압력 이상으로 증기압이 상승되는 경우 높은증기 압력이 체결부재(2)의 통공(2a)를 폐쇄하고 있는 플란자(33)의 선단부(33b)에 작용됨에 따라 플란자(33)는 걸림부(33c)로 하여금 고정철심(3)사이에 장착된 탄성부재(1)를 가압하면서 통공(2a)이 개방되어 조리실(S)의 증기압력은 통공(2a)→요동영역(P)을 경유하여 증기통로(33a)(32a)→통공(3a)을 통과하여 외부로 배출된다. 이와같이 증기배출로 증기압력이 안전압력 (탄성부재(1)의 복원력과 동일한 압력)이하로 낮아지게되면, 플란자(33)는 다시 탄성부재(1)의 복원력이 작용되어 조리실(S)에 노출되어 있는 통공(2a)을 도면 제3도의 a, b에 도시된 바와같이 개방과 폐쇄하는 동작을 반복한다.As described above, when the pressure of the cooking chamber S of the inner container 10 rises above the safety pressure due to the restoring force of the elastic member 1, the planar 33 closes the through hole 2a. As the steam pressure acts on the tip portion 33b of the planar 33 closing the through hole 2a of the fastening member 2, the planar 33 causes the catching portion 33c to be held between the fixed iron cores 3. The through hole 2a is opened while pressing the elastic member 1 mounted thereon so that the vapor pressure of the cooking chamber S is passed through the through hole 2a to the swinging area P. It is discharged to outside through 3a). When the vapor pressure is lowered below the safety pressure (same pressure as the restoring force of the elastic member 1) by the steam discharge, the planar 33 is exposed to the cooking chamber S by restoring the elastic member 1 again. The opening and closing operations of the through holes 2a as shown in a and b of FIG. 3 are repeated.

상기와 같은 동작으로 인하여 최소한 조리실(S)의 증기압력증대로 인한 위험상황이 발생되지 않도록한 안전밸브로서의 역할을 수행하게된다.Due to the operation as described above to serve as a safety valve to prevent the dangerous situation caused by the increase in the steam pressure of the cooking chamber (S) at least.

또, 전기보온압력밥솥의 조리하고자하는 메뉴에 따라 솔레노이드(30)를 구성하고 있는 코일(31)에 전기가 통전되면, 고정철심(32)에 발생되는 자기력이 플란자(33)에 작용됨에 따라 플란자(33)는 고정철심(32)의 요동영역(P)내에서 인력에 의하여 탄성부재(1)를 가압하면서 이동하여 플란자(33)의 선단부(33b)에 의해 체결부재(2)의 통공(2a)에 대한 폐쇄상태를 개방상태로 도면 제3도의 b에 도시된 바와같이 유지시키게된다.In addition, when electricity is supplied to the coil 31 constituting the solenoid 30 according to the menu to be cooked of the electric thermal pressure cooker, as the magnetic force generated in the fixed iron core 32 is applied to the planar 33 The planar 33 moves while pressing the elastic member 1 by the attractive force in the swinging area P of the fixed iron core 32, and the fastening member 2 is moved by the distal end portion 33b of the planar 33. The closed state to the through hole 2a is kept open as shown in b of FIG. 3.

이와같이 체결부재(2)의 통공(2a)이 개방상태가 되면 조리실(S)의 압력은 대기압과의 평형유지를 위해 고압의 증기압은 통공(2a)→요동영역(P)을 경유하여 증기통로(33a)(32a)→통공(3a)를 외부로 배출되는 것이다.When the through hole 2a of the fastening member 2 is opened as described above, the pressure in the cooking chamber S is maintained at equilibrium with the atmospheric pressure, and the high pressure vapor pressure passes through the through hole 2a → swing region P. 33a) (32a) → the through hole (3a) is discharged to the outside.

한편, 솔레노이드(30)에 전원 단전상태가 되면 플란자(33)는 자기력으로 부터 해제되어 탄성부재(1)의 복원력에 의하여 플란자(33)의 선단부(33b)로 하여금 체결부재(2)의 통공(2a)을 폐쇄동작을 하게되는 것이다.On the other hand, when the solenoid 30 is in the power disconnection state, the planar 33 is released from the magnetic force, and the front end portion 33b of the planar 33 causes the fastening member 2 of the fastening member 2 by the restoring force of the elastic member 1. It is to close the through-hole (2a).

이상에서와 같이 본 고안은 솔레노이드(30)의 기본구성에 해당하는 고정철심(32)과 플란자(33)에 대해 증기통로(32a)(33a)를 구비하고, 상기 플란자(33)와 고정철심(32) 사이에 탄성부재(1)를 배치 조립하고, 해당 조립체를 밥솥의 조리실(S)과 외부를 연통되게 부설하여 솔레노이드(30)에 전원 통전과 단전에 따라 조리실(S)과 외부와의 연통된 증기통로를 개방 또는 폐쇄동작을 실현토록 했다는 것과, 탄성부재(1)의 복원력으로 조리실(S)의 안전압력을 유지할수 있도록 했다는데 그 기술적 특징이며, 그로인해, 구조적인 단순화로 안전밸브로서의 역할과 전기적인 신호에 따라 증기배출경로에 본 고안이 적용될 수 있는 밥솥은 전기를 이용하여 조리할 수 있는 전기압력밥솥에 적용할수 있는 것이다.As described above, the present invention includes steam passages 32a and 33a for the fixed iron core 32 and the planar 33 corresponding to the basic configuration of the solenoid 30, and is fixed with the planar 33. The elastic member 1 is disposed and assembled between the iron cores 32, and the assembly is placed in communication with the cooking chamber S of the rice cooker so that the outside is in communication with the cooking chamber S and the outside according to the energization and power failure of the solenoid 30. The opening and closing operation of the steam passage connected to each other is realized, and the safety pressure of the cooking chamber S can be maintained by the restoring force of the elastic member 1, which is a technical feature. According to the role of the valve and the electrical signal, the rice cooker to which the present invention can be applied to the steam discharge path is applicable to the electric pressure cooker that can be cooked using electricity.
