본 발명은 전기밥솥에서 밥맛이 변하지 않게 하기 위한 새로운 보온 방법으로 진공펌프와 전자회로로써 진공 보온병의 원리를 전기밥솥에 적용하고 진공펌프의 동작에 따른 문제점을 해결하고 밥솥의 진공을 위한 구조와 보온을 위한 방법 및 장치이다.The present invention is a new thermal insulation method for changing the taste of rice in an electric rice cooker as a vacuum pump and an electronic circuit to apply the principle of the vacuum thermos to the electric rice cooker and solve the problems caused by the operation of the vacuum pump and the structure and insulation for the vacuum of the rice cooker Method and apparatus for.
종래 전기 밥솥은 전자회로에 의해서 보온하였으므로 시간이 흐를수록 밥맛은 변하였다.Since the conventional electric rice cooker was insulated by an electronic circuit, the taste of rice changed as time passed.
본 발명은 상기와 같은 문제점을 해소하기 위한 것으로써 밥솥 하부에 진공 펌프를 설치하고 밥솥통 외부를 진공이 유지되기 위한 구조를 만들고 전자회로로 진공펌프의 동작을 제어하는 진공 전기밥솥에 대한 방법 및 장치이다.The present invention is to solve the above problems by installing a vacuum pump in the bottom of the rice cooker and the structure for maintaining the vacuum outside the rice cooker and a method for a vacuum electric rice cooker to control the operation of the vacuum pump by an electronic circuit and Device.
이하, 본 발명을 첨부 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
밥솥외통(1)의 수평, 수직결합부(1')(1)는형태로 되고, 뚜껑(2)의 밥솥통 결합부(2')는형상으로형태의 고무실(7)을 강한 압력으로 눌러 결합시킨다. 이 고무실(7)은 뚜껑(2)이 닫히면 밥솥외통(1)의 수평결합부(1')에 압착된다. 이 압착의 힘은 손잡이(3) 상걸립편(4)의 걸림턱(4')과 밥솥외통(1)의 하걸림편(5)의 돌출부(5')가 걸림 결합되었을 때 1차 (SEAL)이 이루어지고 진공펌프(6)가 동작시는 고무실(7)이 진공의 힘에 의해 당겨져 수직 결합부(1)에 2차 실(SEAL)이 이루어진다.Horizontal and vertical coupling portion (1 ') (1) of the rice cooker outer cylinder (1) Form, and the rice cooker coupling portion 2 'of the lid 2 In shape The rubber chamber 7 of the form is pressed by a strong pressure. The rubber chamber 7 is pressed against the horizontal coupling portion 1 'of the rice cooker outer cylinder 1 when the lid 2 is closed. This pressing force is the primary when the locking jaw 4 'of the upper grip piece 4 of the handle 3 and the protrusion 5' of the lower locking piece 5 of the rice cooker 1 are engaged. ) And the rubber chamber 7 is pulled by the force of the vacuum when the vacuum pump 6 is operated to form a secondary seal (SEAL) on the vertical coupling portion (1).
밥솥외통(1)과 뚜껑은 압력에 견디기 위해 금속재질이며, 금속 재질은 열전도가 높아 내부에 상,하절열체(10)(11)를 넣고 보온히터선(12)을 감은 뚜껑내판(13)과 밥솥내판통(14)을 뚜껑(2)과 밥솥외통(1)에 고정되고 밥솥(15)은 하부절열체(17)에 의해 고정된 취사히터(18) 위에 안착되며 밥솥내판통(14)과는 직접 접촉없이 일정 간격을 두게된다. 밥솥뚜껑(16)은 밥솥(15)의 위에 안착 되면서 밥솥실(16')에 밥솥 내부는 별도로 밀폐된다. 밥솥뚜껑(16)에는 압력을 배출하기 위한 공(19)을 설치하여 압력 밀폐판(8)이 뚜껑(2)을 약하게 누르고 있기에 취사시 취사 압력을 외부로 배출시킨다.The rice cooker outer cylinder (1) and the lid is made of metal to withstand pressure, and the metal material has a high thermal conductivity, and the upper and lower heating elements (10) and (11) are placed inside, and the inner lid (13) wound with a warm heater wire (12). The rice cooker inner tube (14) is fixed to the lid (2) and the rice cooker outer cylinder (1) and the rice cooker (15) is seated on the cooking heater (18) fixed by the lower heating element (17) and the rice cooker inner tube (14) Will be spaced without direct contact. The rice cooker lid 16 is seated on the rice cooker 15, and the inside of the rice cooker is separately sealed in the rice cooker chamber 16 ′. The rice cooker lid 16 is provided with a ball 19 for discharging the pressure so that the pressure-sealing plate 8 slightly presses the lid 2 to discharge the cooking pressure to the outside during cooking.
진공펌프(6)는 밥솥외통(1)의 하부에 설치되며 취사에서 보온으로 넘어가면 마이크로 스위치(29)가 취사모드(29')에서 보온모드(29)로 전환되고 전류가 트랜스(34)에 흐르고 직류 전류는 저항(32)을 통해 TR2(32)의 베이스에 전압이 걸려 콜렉터 에미터간에 도통되어 모타(6')가 구동되어 펌프(6)는 작동하여 밥솥외부공간(15')과 밥솥상공간(13') 밥솥하공간(14')을 진공으로 만든다.The vacuum pump 6 is installed at the bottom of the rice cooker outer cylinder 1 and when the micro switch 29 is turned into the warming mode 29 in the cooking mode 29 'when the water is passed from the cooking to the warming, the current is transferred to the transformer 34. The DC current flows through the resistor 32 to the base of the TR2 32 so that it is conducted between the collector emitters and the motor 6 'is driven so that the pump 6 is operated so that the cooker outer space 15' and the rice cooker are operated. The upper space 13 'is made under vacuum in the cooker lower space 14'.
이때 진공도가 낮아지면 진공센서(23)의 스위치레버는 이동되고 스위치(23')는 ON 되어 TR1(31)의 베이스에 전압을 걸어 TR2(32)의 베이스 전류를 어스시켜 진공펌프(6)의 구동을 멈추게한다.At this time, when the degree of vacuum decreases, the switch lever of the vacuum sensor 23 is moved and the switch 23 'is turned on to apply a voltage to the base of the TR1 31 to ground the base current of the TR2 32 so that the vacuum pump 6 Stops driving
뚜껑의 누름버턴(25)을 누르면 누름 스위치(26)가 ON 되어 솔레노이드 밸브(27)가 열려 진공이 제거되면서 TR1(31)의 베이스에 전압이 걸려 진공 펌프(6)는 동작하지 않는다. 이때 진공센서(23)의 스위치레버는 후진되어 전류는 차단되고, 뚜껑(2)이 열리면 뚜껑 스위치(22)가 ON 되어 TR1(31)의 베이스에 접압이 걸려 진공펌프(6)는 동작하지 않는다.When the push button 25 of the lid is pressed, the push switch 26 is turned on, the solenoid valve 27 is opened, and the vacuum is removed to apply a voltage to the base of the TR1 31 so that the vacuum pump 6 does not operate. At this time, the switch lever of the vacuum sensor 23 is reversed to cut off the current, and when the lid 2 is opened, the lid switch 22 is turned on, and the vacuum pump 6 is not operated because the pressure is applied to the base of the TR1 31. .
뚜껑을 닫으면 뚜껑 스위치(22)가 차단되어 전류의 흐름도 차단되나 콘덴서(33)의 충전 전류가 남아있어 타임회로가 구성되어 5∼30분 뒤에 충전 전류가 방전되면 TR1(31)의 베이스에 인가 전압이 없어지면 진공펌프(6)는 동작한다.When the lid is closed, the lid switch 22 is cut off and the flow of current is cut off, but the charging current of the capacitor 33 remains so that a time circuit is formed, and when the charging current is discharged 5 to 30 minutes later, the voltage applied to the base of the TR1 31 is applied. When this disappears, the vacuum pump 6 operates.
미설명부호는 하 케이스(30), 정류다이오드(35), 콘덴서(36), 저항(39), 보온 네온 램프(28), 취사 네온램프(29)이다.Reference numerals are lower case 30, rectifier diode 35, capacitor 36, resistor 39, heat insulating neon lamp 28, cooking neon lamp 29.
이와 같이 구성된 본 발명은 보온시 밥솥외부공간(15')과 밥솥상공간(13') 밥솥하공간(14')을 진공으로 만들고, 보온히터선(12)은 진공 속에서 열을 발산하므로 밥솥(15)에 열을 직접 전달하지 않으면서 밥솥의 열을 외부로 빠져나가는 손실을 막아 일정 시간 밥맛이 변하지 않게 된다.The present invention configured as described above makes the cooker outer space 15 'and the cooker upper space 13' and the cooker lower space 14 'into a vacuum, and the heat insulation heater 12 emits heat in a vacuum, so the cooker The rice taste does not change for a certain time by preventing loss of escaping the heat of the rice cooker without transferring heat directly to (15).
