도 2에 있어서, 본 고안은 내솥용기(12)와 연통되게 제1증기배출구(2)와 솔레노이드밸브인 제2증기배출구(3)가 설치된 전기압력 보온밥솥에 있어서, 상기 내솥용기(12)와 연통되게 설치되어 내솥내의 증기압 팽창에 따라 그 높,낮이가 변화되는 주름관(4)이 더 포함된다.In FIG. 2, the present invention is an electric pressure thermal rice cooker provided with a first steam outlet (2) and a second steam outlet (3) which is a solenoid valve to communicate with the inner pot container (12), the inner pot container (12) and It is further provided with a corrugated pipe (4) is installed in communication with the height, the height is changed in accordance with the expansion of the vapor pressure in the inner pot.

여기서, 상기 주름관(4)은 높,낮이 이동이 용이하도록 그 측면에 주름(4c)이 형성되는 한편, 주름관(4)의 상부로 돌출형성된 돌기(4b) 및 내솥용기에 용접 등으로 고정되는 소정길이로 연장형성된 지지편(4a)이 형성된다.Here, the corrugated pipe (4) is formed on the side of the corrugation (4c) to facilitate the movement of height, height, while being fixed to the projection (4b) and the inner pot container formed by protruding to the upper portion of the corrugated pipe (4) The support piece 4a extended by the predetermined length is formed.

상기 스위치 접점신호는 증기배출구의 고장으로 인한 설정과압 이후에 동작되는 것이 그 동작상 바람직하다.The switch contact signal is preferably operated after the set overpressure due to a failure of the steam outlet.

이상의 설명은 본 고안의 일 실시예에 불과하며, 본 고안의 그 구성요지 범위내에서 예컨대, 주름과의 형상, 돌기 등 얼마든지 변경 및 개조가 가능하다.The above description is only one embodiment of the present invention, and within the scope of the present invention, for example, the shape of the wrinkles, projections, etc. can be changed and modified as much as possible.

상술한 바와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

먼저, 본 고안은 공지의 제1증기배출구(2) 및 제2증기배출구(3)로써 밥솥내의 압력에 따라 증기를 배출시키는 안전수단 외에 과압경보장치가 구비되는 바, 이 과압경보장치는 일정기압에서 증기배출구가 개방되어 증기를 배출되지 못한 시점에서 동작된다.First, the present invention is provided with an overpressure alarm device in addition to the safety means for discharging steam according to the pressure in the rice cooker as the first steam outlet (2) and the second steam outlet (3), the overpressure alarm device is a constant pressure In this case, the steam outlet is opened and the steam is not discharged.

즉, 제1증기배출구(2) 및 제2증기배출구(3)의 고장으로 인해 내솥내부가 비정상적인 과압상태로 되면 주름관(4)으로 유입되는 증기압 팽창에 의해 양측의 주름(4C)이 늘어나 소정길이까지 연장되고, 이에 주름관(4) 상부에 형성된 돌기(4b)가 입력수단(7)의 스위치(SW)를 접촉 온시킨다.That is, when the inner pot is abnormally overpressured due to the failure of the first steam outlet 2 and the second steam outlet 3, the wrinkles 4C on both sides are increased by the expansion of the steam pressure introduced into the corrugated pipe 4, and the predetermined length is increased. It extends to this, the projection 4b formed on the corrugated pipe 4 is in contact with the switch SW of the input means (7).

이어, 상기 스위치(SW) 온은 전압(Vcc)이 풀업저항(R1)을 통해 접지측으로 흐르게 되면서 로우전위(0V)가 제어수단(5)의 입력단(PI1)으로 입력되며, 상기 제어수단(5)은 과압상태로 판단하여 출력단(PO1)인 경보수단(6)에 소정의 경보음신호를 출력한다. 이 경보음 출력신호로 경보수단(6)의 트랜지스터(Q)를 턴온시켜 부져(B)가 동작되도록 함으로써 경보음이 발하도록 한다.Subsequently, as the switch SW is turned on, as the voltage Vcc flows to the ground side through the pull-up resistor R1, the low potential 0V is input to the input terminal PI1 of the control means 5, and the control means 5 Is judged to be an overpressure state and outputs a predetermined alarm sound signal to the alarm means 6 which is the output terminal PO1. The alarm sound is output by turning on the transistor Q of the alarm means 6 with the alarm sound output signal to cause the buzzer B to operate.

그리하여 사용자가 경보음을 듣고 적절히 과압상태를 해제시키면 이에 주름관(4)으로 유입되는 증기압이 적어짐에 의해 양측의 주름(4C)이 줄어들어 원래의 상태로 복귀되고, 주름관(4)의 돌기(4b)가 스위치(SW)와 이격되어 스위치접점이 오프된다. 상기 스위치(SW) 오프는 전압(Vcc)이 풀업저항(R1)을 통해 고전윈(5V)가 제어수단(5)의 입력단(PI1)으로 입력되며, 상기 제어수단(5)은 과압해제 상태로 판단하여 출력단(PO1)인 경보수단(6)에 소정의 경보음 차단신호를 출력한다. 이 경보음 차단 출력신호로 경보수단(6)의 트랜지스터(Q)를 턴오프시켜 부져(B)가 동작되지 않도록 함으로써 경보음 발생을 멈춘다.Thus, when the user hears the alarm sound and releases the overpressure state appropriately, the steam pressure flowing into the corrugated pipe 4 decreases, thereby reducing the corrugations 4C on both sides and returning to the original state, and the projection 4b of the corrugated pipe 4 is reduced. Is spaced apart from the switch SW and the switch contact is turned off. In the switch SW off, the high voltage 5V is input to the input terminal PI1 of the control means 5 through the pull-up resistor R1, and the control means 5 is in the overpressure release state. Judgment outputs a predetermined alarm sound blocking signal to the alarm means 6 which is the output terminal PO1. The alarm sound generation output is stopped by turning off the transistor Q of the alarm means 6 with the alarm sound interruption output signal so that the buoy B is not operated.

이상에서 살펴본 바와 같이 본 고안은 과압력상태를 적절한 시점에서 해결을 유도케 하는 과압경보장치를 부가함으로서, 압력밥솥의 안전사용에 기여함과 더불어 기능추가로 인한 제품의 신뢰도를 향상시키는데도 유용한 효과가 있다.As described above, the present invention adds an overpressure alarm device that induces an overpressure condition to be resolved at an appropriate time point, which contributes to the safe use of the pressure cooker and also improves the reliability of the product due to the addition of functions. There is.
