본 발명은 전기압력밥솥에 관한 것으로서, 더욱 상세하게는 과다한 양의 증기가 배출되는 것을 해소할 수 있는 수단이 구비된 전기압력밥솥의 증기배출장치에 관한 것이다.The present invention relates to an electric pressure cooker, and more particularly, to a steam discharge device of the electric pressure cooker having a means for eliminating the discharge of excessive amount of steam.

일반적으로 전기압력밥솥의 증기배출장치는 덮개에 설치되어, 내부의 압력이 일정압력 이상이 되면 증기가 외부로 배출되도록 하여, 내부의 압력을 일정하게 유지하도록 하는 장치이다.In general, the steam discharge device of the electric pressure cooker is installed on the cover, so that the steam is discharged to the outside when the pressure inside the predetermined pressure or more, it is a device to maintain the pressure inside.

상기 증기배출장치의 전형적인 실시예를 첨부 도면에 의하여 상세하게 설명하면 다음과 같다.Exemplary embodiments of the vapor discharge device will be described in detail with reference to the accompanying drawings.

도 1a,b에 도시한 바와 같이, 전기압력밥솥의 증기 배출장치는 상기 덮개(미도시)의 하면을 구성하는 하부 덮개(10)와, 하부 덮개에는 밥솥 내부에서 발생하는 증기를 증기배출장치내로 유입시키기 위한 증기유입구(11)와, 상기 증기유입구의 개폐를 위해 하면이 패킹(packing)(23)으로 구비된 핀(22)과, 상기 핀이 케이스(20)에 스프링(24)으로 결합되어 있고, 증기배출구(21)를 구비한 상기 케이스는 스크류(screw)(25)에 의해 상기 하부덮개(10)에 고정되어 구비되어 있다.As shown in Figure 1a, b, the steam discharge device of the electric pressure cooker has a lower cover 10 constituting the lower surface of the cover (not shown), and the lower cover is steam generated in the rice cooker into the steam discharge device A steam inlet 11 for inflow, a pin 22 having a lower surface as a packing 23 for opening and closing the steam inlet, and the pin are coupled to the case 20 by a spring 24. The case having the steam outlet 21 is fixed to the lower cover 10 by a screw 25.

상기와 같이 구성된 증기배출장치는 전기압력밥솥 내부의 압력이 일정압력 이상이 되면 스프링(24)이 압축되면서 상기 패킹이 부착된 핀(22)이 상승하게 된다.In the steam discharge device configured as described above, when the pressure inside the electric pressure cooker becomes a predetermined pressure or more, the spring 24 is compressed and the pin 22 with the packing is raised.

따라서, 증기유입구(11)가 개방되어 밥솥 내부의 증기가 상기 케이스(20) 내부로 유입된 후, 상기 증기배출구(21)을 통해 전기압력밥솥 외부로 배출되게 된다.Therefore, after the steam inlet 11 is opened and the steam inside the cooker is introduced into the case 20, the steam inlet 11 is discharged to the outside of the electric pressure cooker through the steam outlet 21.

하지만, 상기한 바와 같이 구성된 증기배출장치는 고장 및 작동불량에 의해증기가 소정량 이상 배출될 경우, 이를 감지하여 부하단의 전원을 차단하고 고장을 알릴 수 있는 수단이 구비되어 있지 않았다.However, the steam discharge device configured as described above is not provided with a means to detect the failure when the steam is discharged more than a predetermined amount due to failure and malfunction, cut off the power of the load stage and inform the failure.

그러므로, 상기와 같은 경우 밥솥 내부의 압력이 떨어져서 내부가 고온,고압을 유지할 수 없게 되어, 밥이 설익게 되는 경우가 발생하는 문제점이 있었다.Therefore, in the case described above, there is a problem that the pressure inside the cooker drops, so that the inside cannot maintain a high temperature and a high pressure, and the rice becomes unripe.

또한, 상기 전기압력밥솥은 하면에 위치한 온도 센서(미도시)를 통해 일정온도가 되었을 때 취반을 종료하도록 구성되어 있다.In addition, the electric pressure cooker is configured to end cooking when the temperature reaches a predetermined temperature through a temperature sensor (not shown) located on the lower surface.

따라서, 압력저하에 의해 상기 밥솥 내부가 일정온도에 도달하지 못할 경우, 상기 밥솥에 전원이 공급되는 시간이 증가되어 소비전력을 낭비하는 원인이 되었다.Therefore, when the inside of the cooker does not reach a certain temperature due to the pressure drop, the time for which power is supplied to the cooker increases, causing a waste of power consumption.

한편, 상기와 같이 과도한 양의 증기가 오랜 시간동안 상기 케이스 내부에 머물게 되는 경우, 상기 케이스와 상기 하부덮개 사이의 결합틈새를 통해 상기 전기압력밥솥의 덮개(미도시) 내부로 증기가 유입되게 된다.On the other hand, when the excessive amount of steam stays inside the case for a long time, the steam is introduced into the cover (not shown) of the electric pressure cooker through the coupling gap between the case and the lower cover. .

따라서, 상기 덮개 내부에 설치되어 있는 전기부품에 증기 응축수가 흡착되어 누전 및 쇼트(short)현상이 발생되는 문제점을 가지고 있었다.Therefore, steam condensed water is adsorbed to the electric parts installed inside the cover, and thus, a short circuit and a short phenomenon occur.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로, 전기압력밥솥의 증기배출장치를 통해 배출되는 증기의 양을 측정할 수 있는 검출수단을 구비한 증기배출장치를 구성함을 그 목적으로 한다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a steam discharge device having a detection means for measuring the amount of steam discharged through the steam discharge device of the electric pressure cooker. .

도 2a,b에 나타난 바와 같이, 본 발명은 증기유입구(110)를 구비한 하부덮개(100)와, 상기 하부덮개에 결합되어 증기배출구(210)를 구비한 케이스 (200)와, 상기 케이스에 탄성부재(320)로 결합되고, 상기 증기유입구의 개폐에 사용되는 하면에 패킹(packing)(310)이 부착된 핀(300)과, 상기 케이스의 일측에 위치하여 상기 증기유입구를 통해 상기 증기배출구로 배출되는 증기의 양을 측정할 수 있는 배출 증기량 검출수단을 구비한 전기압력밥솥의 증기배출장치가 제공된다.As shown in Figure 2a, b, the present invention is a lower cover 100 having a steam inlet 110, and a case 200 having a steam outlet 210 is coupled to the lower cover and the case The pin 300 is coupled to the elastic member 320, the packing 310 is attached to the lower surface used for opening and closing the steam inlet, and located on one side of the case and the steam outlet through the steam inlet Provided is a steam discharge device for an electric pressure cooker having a discharge steam amount detecting means capable of measuring the amount of steam discharged into the furnace.

상기 검출수단은 상기 케이스 일측에 부착되어, 증기 응축수의 전기전도성을 이용하기 위해서 통전성 재료로 구성된 한쌍의 프로브(400)가 구비된다.The detecting means is attached to one side of the case, and is provided with a pair of probes 400 made of an electrically conductive material in order to use the electrical conductivity of the steam condensate.

이 경우에 있어서, 상기 프로브(400)는 상기 케이스(200)를 관통하여 내부와 외부로 돌출되도록 구비하고, 두 프로브 사이에 소정의 간극을 둠으로써 과열된 증기가 상기 프로브 사이에 흡착된후 상기 프로브의 열전달에 의해 응축수로 형성되게 한다.In this case, the probe 400 is provided to penetrate the case 200 to the inside and the outside, and by placing a predetermined gap between the two probes, after the superheated steam is adsorbed between the probes, The heat transfer of the probe causes it to form into condensate.

한편, 상기 케이스의 외부로 나와있는 상기 프로브(400)의 끝단과 상기 전기압력밥솥에 구비된 제어부(미도시)는 전선(410)으로 연결되어 있고, 상기 프로브에 전류가 인가되도록 구비되어 있다.On the other hand, the end of the probe 400 and the control unit (not shown) provided in the electric pressure cooker that is out of the case is connected by a wire 410, it is provided so that the current is applied to the probe.

이하, 상기 증기배출장치의 작동과정을 설명하면 다음과 같다.Hereinafter, the operation of the steam discharge device will be described.

상기 전기압력밥솥에 부하가 인가되고, 상기 전기압력밥솥 내부가 가열되어 증기가 발생하게 되면, 내부의 온도와 압력은 급격히 증가하게 된다.When a load is applied to the electric pressure cooker and the inside of the electric pressure cooker is heated to generate steam, the temperature and pressure therein increase rapidly.

하지만, 상기 전기압력밥솥 내부의 압력이 설정압력 이상으로 증가하면, 내부 압력에 의해 탄성부재(320)가 압축되어 증기유입구(110)를 개방하게 된다.However, when the pressure inside the electric pressure cooker increases above the set pressure, the elastic member 320 is compressed by the internal pressure to open the steam inlet 110.

따라서, 상기 밥솥 내부의 증기가 증기유입구(110)와 증기배출구(210)를 통해 외부로 배출됨으로써 내부의 압력이 감소되어 일정 압력을 유지하게 된다.Therefore, the steam inside the cooker is discharged to the outside through the steam inlet 110 and the steam outlet 210 to reduce the internal pressure to maintain a constant pressure.

한편, 상기 케이스 내로 유입되는 증기의 양은 한쌍의 프로브(400)에 의해측정되어 진다.On the other hand, the amount of steam introduced into the case is measured by a pair of probes (400).

즉, 상기 프로브의 일측은 과열증기에 의해 고온이 되고, 상기 케이스의 외부로 돌출된 타측은 실온을 유지함으로써, 상기 프로브 일측에서 타측으로 열전달이 일어나게 된다.That is, one side of the probe becomes high temperature due to superheated steam, and the other side protruding to the outside of the case maintains room temperature, thereby causing heat transfer from one side of the probe to the other side.

따라서, 상기 프로브는 과열된 증기보다 낮은 온도를 유지하게 되어, 상기 케이스 내부에서 증기는 상기 프로브에 흡착하여 응축수를 형성하게 된다.Thus, the probe maintains a temperature lower than the superheated steam, so that the steam is adsorbed to the probe to form condensed water.

이렇게 응축된 응축수는 증기배출이 계속되면 지속적으로 생성되고, 응집력에 의해 큰물방울(420)로 성장하여, 상기 프로브 사이를 연결하는 매개물로 형성되며, 상기 응축수의 전기전도성을 통해 전원이 인가되어 있던 상기 프로브 사이에 전류가 흐르게 된다.The condensed water condensed as described above is continuously generated when the steam is discharged, grows into large droplets 420 by cohesion, and is formed as a medium for connecting the probes, and power is applied through the electrical conductivity of the condensate Current flows between the probes.

한편, 상기와 같이 구성된 전기압력밥솥은 도 3에 나타낸 제어 흐름도에서와 같은 제어방법을 따라 제어되게 된다.On the other hand, the electric pressure cooker configured as described above is to be controlled in accordance with the control method as in the control flowchart shown in FIG.

즉, 상기 전기압력밥솥의 가열(S1)단계에서 발생된 증기는 상기 증기배출장치를 통해 배출되며, 배출되는 증기중 일부는 한쌍의 프로브에 흡착된 후 상기 케이스의 내외부로 관통된 상기 프로브의 내부와 외부의 온도차이에 의한 열전달 작용으로 상기 증기는 응축수로 맺히게 된다.That is, the steam generated in the heating (S1) step of the electric pressure cooker is discharged through the steam discharge device, and some of the discharged steam is adsorbed by a pair of probes and then penetrated into and out of the case The steam is condensed by condensed water due to heat transfer due to a temperature difference between and outside.

이후, 흡착된 증기 응축수에 의해 상기 프로브 사이에 흐르는 전류의 양을 측정하는 단계(S2)를 거치게 된다.Thereafter, the step of measuring the amount of current flowing between the probes by the adsorbed vapor condensate (S2).

그리고, 상기 프로브 사이에 흐르는 전류를 측정하여 제어부에서 미리 설정된 설정전류량과 비교연산(S3)하는 단계에서, 측정전류가 설정전류 이하일 경우는상기 전기압력밥솥의 공정이 설정된 작동방법(S5)에 따라 지속적으로 유지된다.And, in the step of measuring the current flowing between the probe and the comparison operation (S3) and the preset current amount set in the control unit, when the measured current is less than the set current, the process of the electric pressure cooker according to the set operation method (S5) Maintained continuously.

하지만, 상기 증기배출장치의 고장 및 작동불량으로 인해 과도한 양의 증기가 배출될 경우, 상기 프로브에 응축되는 응축수의 양도 증가하게 된다.However, when an excessive amount of steam is discharged due to a failure and malfunction of the steam discharge device, the amount of condensed water condensed on the probe also increases.

그러므로, 상기 프로브간에 전류가 흐를수 있는 단면적이 증가하게 되어 상기 프로브간의 전류량이 증가한다.Therefore, the cross-sectional area through which current can flow between the probes increases, thereby increasing the amount of current between the probes.

이때, 측정전류가 설정전류를 초과하게 되면, 제어부를 통해 부하단의 전원을 차단(S7)하게 되어 이하 공정이 중지되고, 상기 전기압력밥솥의 외부에 설치된 알림수단을 통해 고장을 표시(S9)하고 경고음으로 알리게 된다.At this time, when the measured current exceeds the set current, the power of the load stage is cut off through the control unit (S7) and the following process is stopped, and the failure is displayed through the notification means installed outside the electric pressure cooker (S9). You will be notified by a beep.

이상에서와 같이, 본 발명은 증기배출장치에 배출되는 증기량을 측정할 수 있는 검출수단을 구비하고, 이를 통해서 전기압력밥솥을 제어할 수 있게 된다.As described above, the present invention is provided with a detection means for measuring the amount of steam discharged to the steam discharge device, through which it is possible to control the electric pressure cooker.

따라서, 증기배출장치의 고장이나 작동불량에 의해 상기 증기배출장치를 통해 소정량 이상의 증기가 배출될 경우, 이를 감지하여 전기압력밥솥의 이하 수행과정을 정지시키고, 알림수단을 통해 고장을 소비자에게 알릴 수 있게 함으로써, 온도와 압력 저하에 의해 밥이 설익게 되는 것을 방지할 수 있다.Therefore, when a predetermined amount or more of steam is discharged through the steam discharge device due to a failure or malfunction of the steam discharge device, it detects this and stops the following process of the electric pressure cooker, and informs the customer of the failure through the notification means. By doing so, it is possible to prevent the rice from being cooked by the temperature and the pressure drop.

또한, 온도상승 저하에 따른 소비전력의 낭비를 초래하는 경우와, 상기 덮개 내부의 전기부품에 증기응축수가 흡착하여 누전 및 쇼트 현상이 발생되는 것을 해소할 수 있게 된다.In addition, it is possible to eliminate the case of causing a waste of power consumption due to a decrease in temperature rise, and the occurrence of a short circuit and a short circuit due to the adsorption of steam condensed water on the electrical parts inside the cover.
