본 고안은 전기압력밥솥에 압력감지장치를 설치한 것에 관한 것으로, 더 자세하게는 압력밥솥내에 분포하는 압력을 감지하여 이를 외부의 표시장치로 전달하도록 함으로서 외부에서도 쉽게 육안으로 확인될 수 있도록 된 전기압력밥솥용 압력감지장치에 관한 것이다.The present invention relates to the installation of a pressure sensing device in an electric pressure cooker, and more specifically, to detect the pressure distributed in the pressure cooker and to transmit it to an external display device, the electric pressure can be easily visually confirmed from the outside. It relates to a pressure sensing device for a rice cooker.

일반적으로 전기압력밥솥은 그 내부에 발열수단이 내장되고, 그 상부에는 밥솥뚜껑이 설치되는 밥솥본체와, 상기 밥솥본체 내부에 밀폐가능하게 안치되는 내솥용기; 등으로 구성된다.In general, the electric pressure cooker has a heat generating means therein, the upper portion of the rice cooker body is installed with a rice cooker lid, the inner pot container is hermetically placed inside the rice cooker body; And the like.

그리고, 상기 밥솥본체(11)에는 제1도에 도시된 바와 같이, 상기 내솥용기(12)와 연통되게 제1증기배출구(20)와 제2증기배출구(30)가 설치되며, 상기 제1증기배출구(20)에는 내솥용기(12)속의 증기를 외부로 강제배출시키는 강제개방장치(미도시)가 연동되게 설치된다.And, as shown in FIG. 1, the cooker main body 11 is provided with a first steam outlet 20 and a second steam outlet 30 in communication with the inner pot container 12, the first steam Discharge port 20 is installed to force the opening device (not shown) for forcibly discharging the steam in the inner pot container 12 to the outside.

이와같이 된 제1증기배출구(20) 및 제2증기배출구(30)는 각각 통상적으로 밥솥내의 압력에 따라 증기를 배출하도록 된 구조로써 제1증기배출구(20)는 약 2기압시, 제2증기배출구(30)는 약 3기압시에 증기를 배출하도록 되어 있는 바, 이러한 각각의 상태에 따라 증기를 배출하도록 된 증기배출구는 그 내부의 증기압조건에 따라 수행되기 때문에 외부에서 이 증기압을 확인하기란 불가능하였다.The first steam outlet 20 and the second steam outlet 30 as described above are typically configured to discharge steam according to the pressure in the rice cooker, and the first steam outlet 20 has a second steam outlet at about 2 atm. (30) is for discharging steam at about 3 atm, and it is impossible to confirm the steam pressure from the outside because the steam outlet is configured to discharge steam according to each of these conditions, according to the steam pressure conditions therein. It was.

물론, 사용자는 제1증기배출구와 제2증기배출구의 동작여부에 따라 그 내부의 증기압상태를 예측할 수는 있지만 실제적으로 정확한 값을 측정하기는 불가능하였다.Of course, the user can predict the internal vapor pressure state according to the operation of the first steam outlet and the second steam outlet, but it was impossible to actually measure the exact value.

이에 따라, 외부에서도 전기압력밥솥내의 증기압력 상태를 쉽게 육안으로 확인할 수 있는 압력감지장치를 요망해 왔다.Accordingly, there has been a demand for a pressure sensing device that can visually check the steam pressure state in the electric pressure cooker from the outside.

It is to be able to check the steam pressure inside the rice cooker, which will be described in detail with reference to the accompanying drawings.

제2도는 본 고안에 따른 전기압력밥솥에 압력감지장치가 설치된 것을 보인 부분단면도이며, 제3도는 본 고안에 따른 압력감지장치의 리드스위치가 각 마이콤에 연결된 것을 보인 개략도이다.2 is a partial cross-sectional view showing that the pressure sensing device is installed in the electric pressure cooker according to the present invention, Figure 3 is a schematic view showing that the reed switch of the pressure sensing device according to the present invention is connected to each micom.

본 고안에 따른 압력감지장치(40)는 내솥용기(12)에 결합되면서 밥솥본체(11)의 밥솥뚜껑 상부로 적정길이 돌출되게 유로(40a)를 가짐과 함께 그 하측으로는 걸림턱(40b)이 형성되며, 그 내부의 측면으로는 각각에 리드스위치(L1)(L2)(L3)(L4)가 부설하여 된 실린더(41)를 설치하되, 상기 실린더(41)의 걸림턱(40b)에 안착되어 유로(40a)를 개폐함과 동시에 리드스위치(L1)(L2)(L3)(L4)를 온/오프시키는 피스톤(42)을 설치하는 한편, 상기 리드스위치(L1)(L2)(L3)(L4)의 접점 전기신호가 마이콤(50)의 입력단(I1)(I2)(I3)(I4)으로 인가되게 연결되고, 상기 마이콤(50)의 출력단(O1)에는 저항(R1), 트랜지스터(Q1), 부져(B)로 구성된 경보부(60)를 연결하며, 또 다른 마이콤(50)의 출력단(O2)에는 저항(R2), 트랜지스터(Q2)에 연결된 디스플레이(D)로 구성된 디스플레이부(70)를 연결하여, 리드스위치(L1)(L2)(L3)(L4)의 접점 이동에 따라 마이콤(50)의 제어에 의해 디스플레이부(70)가 구동제어되도록 구성한다.The pressure sensing device 40 according to the present invention is coupled to the inner pot container 12 while having a flow path 40a to protrude an appropriate length to the upper portion of the cooker lid of the cooker body 11, and a locking jaw 40b to the lower side thereof. And a cylinder 41 having reed switches L1, L2, L3, and L4 installed on each side thereof, and is provided on the latching jaw 40b of the cylinder 41. The piston 42 is mounted to open and close the flow path 40a and simultaneously turn on / off the reed switches L1, L2, L3, and L4, while the reed switches L1, L2 and L3. L4 is connected to an input terminal I1 (I2) (I3) (I4) of the microcomputer 50, and a resistor R1 and a transistor at the output terminal O1 of the microcomputer 50. (Q1), the alarm unit 60 consisting of a buzzer (B) is connected, and another display unit consisting of a display (D) connected to a resistor (R2) and a transistor (Q2) at the output terminal (O2) of the microcomputer 50 ( 70), reed switch (L1) The display unit 70 is controlled to be driven by the control of the microcomputer 50 according to the movement of the contacts L2, L3, and L4.

이와같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

먼저, 리드스위치(L1)(L2)(L3)(L4)의 각 접점이동에 따른 마이콤(50)의 입력단(I1)으로 그 소정치의 전압이 입력되고 마이콤(50)에서 각 해당수치를 디스플레이(D)시킴에 있어 해당 리드스위치에 대한 수치가 미리 마이콤(50)에 인식되도록 한다.First, a voltage of a predetermined value is input to the input terminal I1 of the microcomputer 50 according to each contact movement of the reed switches L1, L2, L3, and L4, and the respective values are displayed on the microcomputer 50. In (D), the value of the corresponding reed switch is recognized in advance by the microcomputer 50.

그리하여, 전기압력밥솥이 소정의 내용물을 충진한 상태에서 동작개시됨에 의해 어느 일정한 증기압이 발생되면 압력감지장치(40)가 동작되는데, 이때 증기압이 증가함에 따라 유로(40a)를 통한 증기압이 피스톤(42)을 강하게 밀면 이 피스톤(42)은 실린더(41) 내측면에 설치된 리드스위치(L1)와 접촉하여 그 내부접점이 온 됨에 따라 이어 마이콤(50)에서는 이를 인식하여 출력단(O2)에 하이신호를 출력시켜 트랜지스터(Q2)를 턴온시켜 다음 디스플레이(D)에 해당수치(1.5기압)가 표시되도록 한다.Thus, when a certain steam pressure is generated by starting operation in a state in which the electric pressure cooker fills a predetermined content, the pressure sensing device 40 is operated. In this case, the steam pressure through the flow passage 40a is increased by the piston ( When the piston 42 is pushed hard, the piston 42 comes into contact with the reed switch L1 installed on the inner surface of the cylinder 41, and the internal contact thereof turns on. Then, the microcomputer 50 recognizes this and a high signal is output to the output terminal O2. The transistor Q2 is turned on so that the corresponding value (1.5 atm) is displayed on the next display (D).

또, 피스톤(42)이 계속하여 증기압에 의해 상승하게 되면 리드스위치(L2)(L3)가 차례로 접촉하고 이어 마이콤(50)의 입력단(I2)(I3) 역시 차례로 접촉 전압신호가 입력됨에 따라 마이콤(50)에서는 이를 인식하여 출력단(O2)에 하이신호를 출력시켜 트랜지스터(Q2)를 턴온시킨 다음 디스플레이(D)에 해당수치(2.0기압)(2.5기압)가 차례로 표시되도록 한다.In addition, when the piston 42 continues to rise by the vapor pressure, the reed switch (L2) (L3) is in contact with each other, followed by the input voltage signal (I2) (I3) of the microcomputer 50 in turn, as the contact voltage signal is input in turn. In operation 50, a high signal is output to the output terminal O2, the transistor Q2 is turned on, and the corresponding value (2.0 atm) (2.5 atm) is sequentially displayed on the display D.

그런데, 증기압이 위험수치까지 상승하게 되는 시점인 리드스위치(L4)에 피스톤(42)이 접촉하게 되면 전술한 바와 같이 동작되어 디스플레이부(70)에 해당수치(3기압)를 표시함과 동시에 마이콤(50)의 다른 출력단(O1)인 트랜지스터(R2)를 턴온시켜 부져를 동작시키는 경보부(60)가 울리도록 함으로써 위험신호로 주위를 환기시키도록 한다.However, when the piston 42 comes into contact with the reed switch L4 at the point where the steam pressure rises to the dangerous value, the piston 42 is operated as described above to display the corresponding value (3 atm) on the display unit 70 and at the same time, By turning on the transistor R2, which is the other output terminal O1 of 50, the alarm unit 60 for operating the buzzer sounds to ventilate the surroundings with a danger signal.

물론, 이와같은 상황에 대비하여 본 고안에서는 실린더(41) 내측면에 별도의 증기배출공(40a)을 구비시켜 소정의 증기가 유로(40a)를 통하여 빠져나가도록 함으로서 위험상황에 대처하도록 하였다.Of course, in preparation for such a situation, a separate steam discharge hole 40a is provided on the inner surface of the cylinder 41 to cope with a dangerous situation by allowing a predetermined steam to escape through the flow passage 40a.

이와같이 본 고안에서는 밥솥내의 압력상태를 육안으로 확인가능한 이점이 있을 뿐만 아니라, 위험한 상태를 대비한 여러 장치들이 구비된 특징이 있다.As such, the present invention not only has the advantage of visually checking the pressure state in the rice cooker, but also has a feature provided with various devices for the dangerous state.
