본 고안은 커피제조기에 있어서 히터의 가열에 의하여 발생되는 증기는 몸체의 내부인 급수통에서만 발생되며 그 증기는 형상기억 합금 스프링을 동작시키는데 이때 증기가 모두 외부로 분산되므로 누전될 염려가 없고 감전사고등을 미연에 방지할수 있게된 커피 제조기의 형상 기억 합금을 이용한 안전장치에 관한 것이다.The present invention is a steam produced by the heating of the heater in the coffee maker is generated only in the water supply tank which is the inside of the body and the steam operates the shape memory alloy spring, at this time all the steam is dispersed to the outside, there is no fear of short circuit and electric shock accident The present invention relates to a safety device using a shape memory alloy of a coffee maker, which can be prevented in advance.

종래의 커피 제조기에 있어서는 급수통에 저장된 물이 급수통로를 통하여 히터가 내장된 가열기에 입수되어 가열된 다음 팽창될 경우 급수통로의 추출구를 통해 여과지를 이용하여 원두커피 분말이 보관된 제조용기에 투입되어 제조된 커피액이 보온용기에 보관이 되게 되어 있기 때문에 내부용적이 작은 급수통로에 있는 작은량의 물을 히터가 가열시키므로 인하여 발열량이 일정한 히터의 열에 의하여 급수통로 내부의 물이 급속히 가열되어 추출을 하므로써 추출구에서 과다한 증기의 누출이 발생되어 외부에 흘러 내리므로 인하여 사용시 외관이 지저분해질 뿐만 아니라 내부의 전열전선에 습기가 닿을 경우 누전으로 인하여 사용자의 감전사고가 일어나 신체를 상해를 입던 결점이 있었다.In a conventional coffee maker, water stored in a water supply tank is supplied to a heater having a heater built therein through a water supply passage, and when heated, and then expanded, into a manufacturing container in which coffee beans powder is stored using a filter paper through an outlet of the water supply passage. Since the prepared liquid is stored in the heat storage container, the heater heats a small amount of water in the water supply passage whose internal volume is small, so that the water in the water supply passage is rapidly heated by the heat of a constant heater. Excessive leakage of steam from the spout caused by the extraction and flows to the outside, which not only makes the exterior dirty, but also causes a user's electric shock due to short circuits when the internal electric wire touches moisture. There was this.

본 고안은 이와같은 종래의 결점을 해결하기 위하여 안출된 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 설명하면 다음과 같다.The present invention has been devised to solve such a conventional drawback and the construction and operation effects by the accompanying drawings are as follows.

일측면에 증기유통구(1)가 뚫려진 몸체(2)의 하단부면에는 고무호스(3)가 끼워진 수출구(4)가 형성되어지되 그 내부면에는 상부면이 패킹(5)으로 감싸여지면서 하부로 외측 둘레면에는 강선스프링(6)이 삽입됨과 동시에 하부로 고정판(7) 이 고정된 밸브축(8) 이 설치되고 또한 몸체(2)의 하단부면에는 자동온도 조절기(9)가 부착된 가열히터(10)가 설치되며 몸체(2)의 좌측으로는 다수의 증기흡입구(11)가 뚫려진 보호망(12)이 고정되는데 이때 보호망(12)의 내부로 삽입되어진 작동축(13)외면에 고정된 고정판(7')과 그 상부면에 형성된 걸림턱(14)의 사이에는 형상기억 합금 스프링(15)이 설치되어지면서 작동축(13)의 하단부면에는 중심축(16)이 연결되어지는데 이때 중심축(16)은 지지부(17)에 고정핀(18)으로 고정되면서 고무호스(3)의 하단부면에 밀착되어 상하로 유동될수 있게 구성되어진 것으로 미설명부호 19는 뚜껑이고, 20은 작동축 안내부인 것이다.On the lower side of the body (2) where the steam flow opening (1) is drilled on one side, an export opening (4) in which a rubber hose (3) is fitted is formed, and the inner surface of the body (2) is wrapped with a packing (5). At the same time, the steel shaft spring 6 is inserted into the outer circumferential surface of the lower part, and at the same time, a valve shaft 8 on which the fixing plate 7 is fixed to the lower part is installed. Heating heater 10 is installed, and the protection net 12, through which a plurality of vapor inlets 11 are drilled, is fixed to the left side of the body 2, at which time the outer surface of the operation shaft 13 inserted into the protection net 12 The shape memory alloy spring 15 is installed between the fixed plate 7 'fixed to the upper end and the locking projection 14 formed on the upper surface thereof, and the central shaft 16 is connected to the lower end surface of the operating shaft 13. At this time, the central shaft (16) is fixed to the support 17 with a fixing pin (18) while being in close contact with the lower end surface of the rubber hose (3) And reference numeral 19 is a lid that been configured to be 20 will deny the operating rod guide.

이와같이 구성된 본 고안은 작동효과를 설명하면 다음과 같다.The present invention configured as described will be described as follows.

커피 제조기의 몸체(2)의 뚜껑(19)을 열고 급수한후 뚜껑(19)을 닫으면 몸체(2)의 내부는 증기유통구(1)를 제외하고는 밀폐상태가 유지되는 상태에서 일단 전원을 넣으면 몸체(2)의 하단부면에 부착된 가열히터(10)가 발열하여 가열되어 몸체(2)내부에 급수된 물은 비등이 되며 증기가 발생되어 몸체(2) 내부의 압력이 상승하는데 이때 발열된 증기는 내부공간이 밀폐되어 있으므로 증기유통구(1)와 통하여 동시에 보호망(12)의 외측 둘레면에 뚫려진 증기흡입구(11)를 통해 형상기억합금스프링(15)에 도달하면서 형상기억합금스프링(15)의 온도는 상승하여 길이가 늘어나고 또한 길이가 늘어나면서 고정판(7')으로 고정된 작동축(13)을 하부로 이동시키는 이때 작동축(13)은 몸체(2)의 작동축 안내부(21)에 의해 상하로만 이동이 되며 작동축(13)이 하부로 이동시 고정핀(18)에 의해 몸체(2)의 지지부(17)에 설치된 중심축(16)을 눌러줌과 동시에 중심축(16)의 타측 단부면에 밀착된 상부면이 패킹(5)으로 감싸여진 밸브축(8)이 중심축(16)에 의해 상부로 이동되면서 수출구(4)가 열려 가열된 물을 고무호스(3)를 통하여 커피 분말이 보관된 제조통으로 보내게 되어 있는 것으로 일단 급수된 물이 모두 추출되면 가열히터(10)의 발열이 누적되어 가열히터(10)에 부착되어 있는 자동온도조절기(9)에 의해 입력전원을 단속하여 일정온도이상으로 과열되는 것을 방지하여 전력의 소모도 방지할수 있을 뿐만 아니라 몸체(2)의 내부에서 발생되는 증기가 없으므로 형상기억 합금스프링(15)의 표면온도는 내려가며 형상기억 합금스프링(15)은 가열전의 원래대로 줄어들고 동시에 작동축(13)이 상부로 이동되고 또한 중심축(16)은 자중으로 우축이 무거우므로 우측이 하무로 내려가고 좌측이 상부로 형상 기억 합금스프링(15)의 이동량 만큼 올라가는데 이때 밸브축(8)은 강선스프링(6)의 늘어나는 힘과 고정판(7)의 고정력에 의해 하부로 내려와 패킹(5)의 작용을 기밀하게 하여 다음 사용시의 급수시에도 수밀작용을 가지게 되어진 것으로 본원을 사용할 경우에는 누전될 염려가 없고 또한 인체에 해를 주는 감전사고등을 미연에 방지할수 있게 된 것이다.Open the lid 19 of the coffee machine body 2, supply water, close the lid 19, and then turn off the power once the body 2 is kept closed except for the steam inlet 1. When it is inserted, the heating heater 10 attached to the lower end surface of the body 2 generates heat and heats the water supplied to the body 2 to boil, and steam is generated to raise the pressure inside the body 2, which generates heat. Since the inner space is sealed, the shape memory alloy spring reaches the shape memory alloy spring 15 through the steam inlet 11 drilled on the outer circumferential surface of the protection net 12 at the same time through the steam flow opening 1. The temperature of (15) is increased to increase the length and also to increase the length of moving the operating shaft 13 fixed to the fixed plate (7 ') to the lower portion at this time the operating shaft 13 is the operating shaft guide of the body (2) It moves only up and down by 21 and fixed when the working shaft 13 moves downward A valve shaft in which an upper surface in close contact with the other end surface of the central shaft 16 is pressed by the packing 5 while pressing the central shaft 16 installed on the support 17 of the body 2 by the 18. (8) is moved upward by the central axis (16), the export port (4) is opened to send the heated water to the manufacturing container where the coffee powder is stored through the rubber hose (3). When all are extracted, the heat generated from the heating heater 10 accumulates and the input power is interrupted by the thermostat 9 attached to the heating heater 10 to prevent overheating above a predetermined temperature, thereby preventing power consumption. In addition, since there is no steam generated inside the body 2, the surface temperature of the shape memory alloy spring 15 is lowered, and the shape memory alloy spring 15 is reduced to its original state before heating, and at the same time, the operating shaft 13 is moved upward. Is moved and the central axis 16 is the right axis Since it is heavy, the right side is lowered to the lower part and the left side is moved upward by the amount of movement of the shape memory alloy spring 15. At this time, the valve shaft 8 is lowered by the stretching force of the steel wire spring 6 and the fixing force of the fixing plate 7. The airtightness of the packing (5) is sealed to have a watertight effect even when water supply is used in the next use, and when the present application is used, there is no risk of short-circuit and it is possible to prevent an electric shock accident and the like that are harmful to the human body. .
