본 고안은 취사완료후 뚜껑개방과정에서 증기배출구를 점차적으로 강제개방하여 증기를 배출케함으로서 뚜껑개방시, 순간적인 증기배출에 따른 폭발상황을 상쇄시킬수 있어 사용의 안전성과 신뢰성을 높일 수 있는 전기보온 압력밥솥의 증기배출구 개폐장치에 관한 것으로, 특히, 증기배출구 개폐장치의 구조를 개량하여 정확한 동작이 이루어지도록함을 목적으로 개발된 전기보온 압력밥솥의 증기배출구 개폐장치에 관한 것이다.The present invention is to force the steam outlet in the process of opening the lid after the completion of cooking to discharge the steam by offsetting the explosion situation due to the instant steam discharge when opening the lid, the electrical insulation to increase the safety and reliability of use The present invention relates to a steam outlet opening and closing device of a pressure cooker, and more particularly, to a steam outlet opening and closing device of an electric thermal pressure cooker developed for the purpose of performing an accurate operation by improving the structure of the steam outlet opening and closing device.

일반적으로 도면 제1도와 같이 도시된 전기보온압력밥솥(A)을 사용함에 있어 서, 밥솥본체(100)내에 안착되는 내부용기(200)와 뚜껑(300)과의 사이를 밀착시켜주거나 밀착해제토록 하기 위해서, 상기 내부용기(200)에 걸림턱(200a)을 형성구비하고, 뚜겅(300)의 회전원판(1)에 상기 내부용기(200)의 걸림턱(200a)과 대응되는 걸림턱(1a)을 형성구비하여 회전원판 조작장치(400)를 이용, 뚜껑의 회전원판(1)을 좌측 또는 우측으로 회전 이동시켜줌에 따라 회전원판(1)이 안내원판(3)에 안내회전되면서, 회전원판(1)의 걸림턱(1a)과 내부용기(200)의 걸림턱(200a)이 상호걸림 또는 걸림해제 작용되고, 또, 뚜껑(300)의고정원판(4)이 패킹(5)으로 밀폐된다.In general, in using the electric thermal pressure cooker (A) shown in FIG. 1, the inner container 200 seated in the cooker body 100 and the lid 300 are brought into close contact or close to each other. To this end, a locking jaw (200a) is formed in the inner container 200, the locking jaw (1a) corresponding to the locking jaw (200a) of the inner container 200 on the rotating disc (1) of the lid 300 By rotating the rotating disc 1 of the lid to the left or right by using the rotating disc operating device 400 to form a rotating disc 1 is guided rotation to the guide disc 3, the rotating disc The catching jaw 1a of (1) and the catching jaw 200a of the inner container 200 are interlocked or released, and the fixing disc 4 of the lid 300 is sealed with the packing 5. .

이에 따라, 뚜껑(300)과 내부용기(200)사이는 밀착되어지거나, 밀착 해제된다.Accordingly, the lid 300 and the inner container 200 is in close contact or is in close contact.

종래의 경우, 전기보온압력밥솥의 증기배출구는 밥솥의 내부 압력이 일정압이상으로 상승될때 그 압력에 의해 개방되어 증기를 배출시키는 구조이다.In the conventional case, the steam outlet of the electric thermal pressure cooker is configured to open by the pressure when the internal pressure of the cooker rises above a predetermined pressure to discharge steam.

즉, 밥솥의 내부압력이 일정압이상일 경우, 증기배출구는 개방되고, 일정압이하일 경우에는 증기배출구를 폐쇄되는 구조이다.That is, when the internal pressure of the rice cooker is above a certain pressure, the steam outlet is open, when the pressure is below a certain pressure, the steam outlet is closed.

그러나, 상기와 같은 방식에 의해서는 밥솥 내부의 증기를 완전히 배출시키기는 불가능하여 밥솥 내부에는 항상 일정압력(추형태의 개폐부재 자중에 해당하는 압력이하)이 걸려있는 상태를 유지하므로서 뚜껑개방시, 순간적인 증기배출에 의해 폭발상황이 발생되어지는 관계로 밥솥사용에 대한 공포감이 유발되었고, 안전성이 결여되는 문제점이 있었다.However, it is impossible to completely discharge the steam inside the rice cooker by the above-described method, so that the inside of the rice cooker is kept under a certain pressure (pressure corresponding to the weight of the opening and closing member in the form of a weight) at the time of opening the lid. Due to the instantaneous discharge of steam caused an explosion situation, a fear of using a rice cooker was caused, and there was a problem of lack of safety.

또한, 상기와 같은 문제점을 해소시키기 위해서 증기배출구를 강제로 개, 폐방시킬 수 있는 증기배출구 강제 개폐장치가 개발되어있으나, 이는 구조적으로 복잡함은 물론 동작이 원활하지 못하여 제기능을 발휘하지 못하므로 기능의 신뢰도가 떨어지는등 여러결점이 있었다.In addition, in order to solve the above problems, a steam outlet forced opening and closing device for forcibly opening and closing the steam outlet has been developed, but this is structurally complicated and the operation is not smooth and does not function properly. There were several drawbacks such as poor reliability.

이에 본 고안은 상기와 같은 종래의 결점을 해소시키기 위해서 전기보온 압력밥솥의 회전원판 소정위치에 경사면을 형성함과, 상기 경사면과의 접촉위치에 따라 상, 하운동하는 레버부재로 이루어진 증기배출구 강제배출장치를 부설하여 사용함으로서, 뚜껑개방과정에서 레버부재가 상향 또는 하향되면서 증기배출구를 강제로 개방 또는 폐쇄시켜주므로, 뚜껑개방시 개방직전전에 밥솥 내부가 대기압상태를 유지하도록됨이 본 고안의 특징적인 기술내용으로서 바람직한 일실시예를 도시한 첨부도면에 의하여 그 구성과 작용효과를 설명하면 다음과 같다.Therefore, the present invention forms a sloped surface at a predetermined position of the rotating disc of the electric thermal pressure cooker in order to solve the above-mentioned drawbacks, and the steam outlet is made up of a lever member which moves up and down according to the contact position with the sloped surface. By installing and using the discharge device, the lever member is upward or downward during the opening of the lid to open or close the steam outlet forcibly, so that the inside of the cooker to maintain the atmospheric pressure just before opening the lid when the feature of the present invention Referring to the accompanying drawings showing a preferred embodiment as a technical description will be described the configuration and effect.

As the rotary disk 1 is circularly moved along the guide disk 3 as it rotates to the left or the right side), the locking jaw 1a and the inner container locking jaw 200a are caught or released, and the lid ( The fixed disk 4 of 300 is in close contact with the inner container 200 through the packing 5, and the opening and closing member 2a in the form of a weight of the steam outlet 2 is opened when the internal pressure is higher than a predetermined pressure. In the structure of the electric thermal pressure cooker (A) in which the steam through the steam guide member (2b) is discharged to the outside, the inclined portion at a predetermined position on the upper surface of the rotating disc (1) S) and the vertical portion of the lever member 6 are inserted through the holes 7a and 3a of the lid outer case 7 and the guiding disc 3, but the projections 7b of the outer case 7 are formed. The spring 9 is installed between the lower end and the fixing pin 8 so that the lever member is elastically lowered, and the roller 10 is placed at the lower end to position the roller within the inclined portion S range. The horizontal portion end of (6) has a configuration in which it is positioned so as to be connected to the lower end of the opening / closing member 2a of the steam outlet 2.

여기서, 스프링(9)는 돌기(7b)와 고정핀(8)에 의해 레버부재(6)에서 이탈되지 않는다. 미설명부호 2c는 증기통로인 것이다.Here, the spring 9 is not separated from the lever member 6 by the projection 7b and the fixing pin 8. Reference numeral 2c is a steam passage.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

본 고안은 전기보온 압력밥솥(A)의 뚜껑(300) 개, 폐방시, 회전원판 조작장치 (400)에 의한 회전원판(1)의 회전동작에 의해 레버부재(6)의 로울러(10)와, 회전원판 (1)에 형성된 경사부(S)와의 접촉위치가 가변됨에 따라 레버부재(6)가 상,하운동하면서 증기배출구(2)의 개폐부재(2a)를 강제로 들어올려 개방시켜 증기를 배출토록함과 추형태의 개폐부재(2a)의 자중에 의해 증기배출구(2)를 폐쇄토록 된 것으로 구체적인 구성부품의 구조 및 그들의 조립구성은 도면 제2도에서와 같은 것으로서, 이를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is a lid 300 of the electric thermal pressure cooker (A), when closed, the roller 10 of the lever member (6) by the rotation operation of the rotating disc 1 by the rotating disc operating device (400) As the contact position with the inclined portion S formed on the rotating disc 1 varies, the lever member 6 moves up and down, forcibly lifting and opening the opening / closing member 2a of the steam outlet 2 to open the steam. The steam outlet 2 is closed by the weight of the opening and closing member 2a in the form of a weight, and the structure of the specific components and their assembly configuration are the same as those in FIG. When described in detail based on the following.

전기보온압력밥솥(A)의 밥솥본체(100)내에 소정의 내용물을 충진시킨 상태의 내부용기(200)를 회전불가능하게 안착시킨 상태에서 밥솥본체(100)에 개폐가능한 구조로 결합된 뚜껑(300)을 닫아주면 뚜껑(300)의 회전원판(1)가장자리상에 일정간격으로 형성된 걸림턱(1a)이 내부용기(200)의 걸림턱(200a)사이사이로 위치되어짐과 동시에 내부용기(200)의 상면과 고정원판(4) 가장자리에 결합된 패킹(5)이 접촉된다.The lid 300 coupled to the cooker body 100 in an openable and closed state in a state in which the inner container 200 in a state in which the predetermined contents are filled in the rice cooker body 100 of the electric thermal pressure cooker A is rotatably seated. ) Close the locking jaw (1a) formed at a predetermined interval on the edge of the rotating disc (1) of the lid 300 is located between the locking jaw (200a) of the inner container 200 and at the same time The packing 5 coupled to the upper surface and the edge of the stationary disk 4 is contacted.

이와같은 상태에서 사용자가 뚜껑(300)의 외부케이스(7)외부로 돌출된 회전원판 조작장치(400)를 닫힘방향(화살표 K방향)으로 회전시키면 이에 연결된 회전원판(1)이 안내원판(3)에 안내회전되어 회전원판(1)의 걸림턱(1a)이 내부용기(200)의 걸림턱(200a)에 걸리게 된다.In such a state, when the user rotates the rotating disc operating device 400 protruding out of the outer case 7 of the lid 300 in the closing direction (arrow K direction), the rotating disc 1 connected thereto is the guide disc 3. The guide jaw (1) of the rotating disc 1 is caught by the locking jaw (200a) of the inner container (200).

따라서 전기보온압력밥솥(A)사용시, 뚜껑(300)이 내부용기(200)로 부터 이탈방지케되어 내부용기(200)와 고정원판(4)사이에서 밀폐력이 유지되며, 또, 패킹(5)이 내부용기(200)에 충분히 밀착되어 틈새를 완벽하게 차단한다.Therefore, when using the electric thermal pressure cooker (A), the lid 300 is prevented from being separated from the inner container 200 to maintain a sealing force between the inner container 200 and the fixed disk (4), and the packing (5) The inner container 200 is sufficiently in close contact with the gap completely.

또한, 상기와같이 회전원판(1)의 회전과정에서, 회전원판(1)에 일체로 형성된 경사부(S)가 일정원주상에서 화살표 "L"방향으로 위치변화되므로서, 뚜껑(300)의 외부케이스(7), 안내원판(3) 구멍(7a)(3a)을 관통하면서 위치고정된 레버부재(6)의 로울러 (10)가 경사부(S)의 경사면을 따라 점차적으로 하향이동된다.In addition, in the rotation process of the rotary disk 1 as described above, the inclined portion S formed integrally with the rotary disk 1 is changed in position in the direction of the arrow "L" on a certain circumference, the outside of the lid 300 The roller 10 of the lever member 6 which is positioned while penetrating the case 7 and the guide disc 3 holes 7a and 3a is gradually moved downward along the inclined surface of the inclined portion S. FIG.

(도면 제3도 b의 화살표 방향)(Arrow direction in Fig. 3B)

이에따라 레버부재(6)의 타측(증기배출구(2)의 개폐부재(2a)하단에 접촉된 부위)이 하향이동되므로 개방된 증기배출구(2)의 개폐부재(2a)가 자중에 의해 닫혀진다.As a result, the other side of the lever member 6 (a portion in contact with the lower end of the opening / closing member 2a of the steam outlet 2) is moved downward so that the opening / closing member 2a of the open steam outlet 2 is closed by its own weight.

계속해서, 회전원판(1)이 완전히 회전이동되어 뚜껑(300)과 내부용기(200)가 완벽하게 결합되면 레버부재(6)의 로울러(10)가 경사부(S) 최저위치에 도면 제3도 a와 같이 도달되어 증기배출구(2)의 개폐부재(2a)는 증기안내부재(2b)의 증기통로(2c)를 완전히 폐쇄시켜준다.Subsequently, when the rotating disc 1 is completely rotated so that the lid 300 and the inner container 200 are perfectly coupled, the roller 10 of the lever member 6 moves to the lowest position of the inclined portion S. Reached as shown in Figure a, the opening and closing member (2a) of the steam outlet (2) completely closes the steam passage (2c) of the steam guide member (2b).

이때, 외부케이스(7)의 돌기(7b)와 레버부재(6)에 삽입된 고정핀(8) 사이에 탄지된 스프링(9)의 탄력이 레버부재(6)를 아랫방향으로 눌러주므로 로울러(10)와 경사부(S)와의 접촉력이 증대되어 원활한 동작을 수행케한다.At this time, the elasticity of the spring 9 held between the protrusion 7b of the outer case 7 and the fixing pin 8 inserted into the lever member 6 presses the lever member 6 downward so that the roller ( 10) the contact force between the inclined portion (S) is increased to perform a smooth operation.

여기서, 레버부재(6)라 함은 경사부(S)와 개폐부재(2a) 사이에 장치되어 경사부(S)와의 관계로 상하이동하여 개폐부재(2a)를 들어올리는 동작과 해당동작이 해제되는 형태의 기술구성이면 충족하다. 따라서, 레버부재(6)라 함은 본 고안의 바람직한 실시예를 도시한 첨부도면에 의할때, 고정핀(8), 스프링(9), 로울러(10)를 포함한다.Here, the lever member 6 is provided between the inclined portion S and the opening / closing member 2a to move up and down in relation to the inclined portion S to lift the opening and closing member 2a, and the corresponding operation is released. If the technical configuration of the form is satisfied. Accordingly, the lever member 6 includes a fixing pin 8, a spring 9, and a roller 10, according to the accompanying drawings showing a preferred embodiment of the present invention.

상기와 같이 뚜껑(300)과 밥솥본체(100)사이에 설치된 증기 배출수단이 완전히 차단되어진 상태에서 전원을 연결하여 취사-뜸 행정을 수행케하여 소정의 내용물을 익힐 수 있다.As described above, the steam discharging means installed between the lid 300 and the rice cooker main body 100 is completely blocked, thereby connecting the power to perform the cooking-moxa stroke to learn the predetermined contents.

한편, 취사-뜸 행정 완료후, (이때, 취사나 뜸행정 수행과정에서 내부압력이 일정압이상일 때에는 증기배출구(2)의 개폐부재(2a) 증기압에 의해 자동 개방되어 증기가 배출되었으므로 내부압은 증기배출구(2)의 개폐부재(2a)를 개방시킬수 있는 힘보다 약한상태이다) 뚜껑(300)과 내부용기(200)의 밀폐상태를 해제하고자 할 경우에는, 사용자가 회전원판(1)에 고정된 회전원판 조작장치(400)를 열림방향으로 돌려주면 회전원판(1)은 안내원판(3)에 가이드되면서 회전이동하여 회전원판(1)의 걸림턱(1a)이 내부용기(200)의 걸림턱(200a)에서 이탈되므로 걸림턱(1a)(200a)이 상호걸림해제된다.On the other hand, after completion of the cooking-moxibustion operation (in this case, when the internal pressure is higher than a certain pressure during the cooking or the operation of the moxibustion operation, the internal pressure is automatically released due to the vapor pressure of the opening / closing member 2a of the steam outlet 2 and the steam is discharged. It is weaker than a force capable of opening the opening / closing member 2a of the steam outlet 2) When the lid 300 and the inner container 200 are to be closed, the user is fixed to the rotating disc 1. When the rotating disc operating device 400 is rotated in the opening direction, the rotating disc 1 is guided by the guide disc 3 to rotate and the locking jaw 1a of the rotating disc 1 is caught by the inner container 200. Since the jaw (200a) is separated from the locking jaw (1a) (200a) is mutually released.

이 과정(회전원판 회전에 의한 걸림판(1a)(200a)의 걸림해제과정)에서, 회전원판(1)에 형성된 경사부(S)의 위치가 일정원주상에서 변화되므로(화살표 K 방향) 레버부재(6)의 하단에 고정된 로울러(10)가 경사부(S)의 경사면에 의해 점차적으로 스프링(9)을 수축시키면서 수직으로 상향이동된다.In this process (the process of releasing the locking plate (1a) (200a) by the rotation of the rotating disk), the position of the inclined portion S formed on the rotating disk 1 is changed in a certain circumference (arrow K direction) lever member The roller 10 fixed to the lower end of (6) is vertically moved upward while gradually contracting the spring 9 by the inclined surface of the inclined portion (S).

이에따라 레버부재(6)의 타측(증기배출구(2)의 개폐부재(2a) 하단에 접촉된 부위)이 상향이동되므로 도면 제3도 a와 같이 닫혀진 증기배출구(2)의 개폐부재(2a)가 강제로 들리면서 열려진다.As a result, the other side of the lever member 6 (a portion in contact with the lower end of the opening / closing member 2a of the steam outlet 2) is moved upward, so that the opening and closing member 2a of the steam outlet 2 closed as shown in FIG. Forcibly heard open

계속해서, 뚜껑(300)의 구성품인 회전원판(1)의 걸림턱(1a)과 내부용기(200)의 걸림턱(200a)이 완전히 상호이격되면 레버부재(6)의 일측이 경사부(S)의 최고위치에 도달되어 증기배출구(2)의 개폐부재(2a)는 도면 제3도 b와 같이 완전히 개방된 상태를 유지한다.Subsequently, when the locking jaw 1a of the rotating disc 1, which is a component of the lid 300, and the locking jaw 200a of the inner container 200 are completely separated from each other, one side of the lever member 6 is inclined (S). The opening position 2a of the steam discharge port 2 is maintained at the highest position of) and remains fully open as shown in FIG.

즉, 뚜껑(300)을 개방하기 위해 회전원판(1)을 회전이동시키는 과정에서 회전원판의 경사부(S)와 레버부재(6)로 이루어진 증기배출구 강제개폐장치가 상호연동되면서 증기배출구의 개폐부재를 점진적으로 개, 폐시킴으로서, 밥솥의 뚜껑개방시, 밥솥내의 증기가 완전히 배출되어짐에 따라 대기압상태를 유지함으로 순간적인 증기 배출에 따른 폭발상황발생을 억제할수 있는 것으로, 사용의 안전성과 신뢰성을 증대시킬수 있을뿐만 아니라 종래것에 비해 구조적으로 단순하여 제작의 용이성, 동작의 원활성을 도모할수 있도록 된 것이다.That is, in the process of rotating the rotary disc 1 to open the lid 300, the steam outlet forced opening and closing device consisting of the inclined portion (S) and the lever member 6 of the rotary disc is interlocked, opening and closing the steam outlet By opening and closing the member gradually, when opening the lid of the rice cooker, the steam inside the rice cooker is completely discharged to maintain the atmospheric pressure to prevent the occurrence of an explosion situation due to instant steam discharge.
