본 고안은 전자시계를 이용하여 예약취사를 행하는 전기밥솥의 예약취사회로에 관한 것이다.The present invention relates to a reservation cooking furnace of an electric rice cooker for making a reservation using an electronic clock.
종래의 예약취사가 가능한 전기밥솥들은 예약취사설정시간의 범위가 12시간이내만이고, 또 매번의 예약취사 설정시마다 설정시점에서의 시각을 확인하고 예약취사시각까지의 시간을 계산하여 설정해야 하는 불편이 있었다.Conventional rice cookers that can be reserved reservation is within 12 hours of the reservation cooking setting time, and each time you set the reservation cooking time to check the time at the time of setting and set up by calculating the time until the reservation cooking time There was this.
본 고안은 종래의 이러한 불편을 전자시계의 출력단에 논리회로를 삽입, 예약취사를 행하는 것으로써 첨부도면에 의거, 그 구조와 작용효과를 상술하면 아래와 같다.The present invention is described in detail the structure and the effect of the conventional inconvenience by inserting a logic circuit to the output terminal of the electronic clock and performing reservation cooking according to the accompanying drawings.
다지탈 전자시계(도시치 않았음)의 오전표시출력단 AM을, 논리회로(20)의 엔드 게이트(3)의 세개의 입력중의 일 입력단에 직접접속하고, 시단위표시부(10)의 'b'세그먼트출력단은 논리회로(20)의 인버터(1)의 입력단에, 'e'세그멘트출력단은 인버터(2)의 입력단에 각기 접속한다.The AM display output terminal AM of the digital electronic clock (not shown) is directly connected to one of three input terminals of the end gate 3 of the logic circuit 20, and the 'b' of the time display unit 10 is connected. The 'segment output stage is connected to the input terminal of the inverter 1 of the logic circuit 20, and the' e 'segment output stage is connected to the input terminal of the inverter 2, respectively.
논리회로(20)의 인버터(1)→(2)의 출력단들은 엔드게이트(3)의 나머지 두 입력단들에 접속되어 있다.The outputs of the inverters 1-2 of the logic circuit 20 are connected to the remaining two inputs of the end gate 3.
또 논리회로(20)의 인버터(2)의 입력, 출력단에는 시각선택스위치(S. W. 1)의 두 접점이 각기 접속되어 있다.In addition, two contacts of the time selection switch S. W. 1 are connected to the input and output terminals of the inverter 2 of the logic circuit 20, respectively.
취사회로(30)의 예약취사선택스위치(S. W. 2)의 접점A는 논리회로(20)의 엔드 게이트(3)의 출력단에, 접점 B는 직류 공급전원 Vcc에, 키 C는 트라이악(TRIAC)의 게이트(G)에 각기 접속되어 있다. 트라이악(TRIAC)의 T1점은 교류전원입력단에 접속되는 동시에 접지되어 있고, T2점은 교류전원 출력단(4)에 접속되어 있다.The contact A of the reserved cooking selection switch SW 2 of the cooking furnace 30 is at the output terminal of the end gate 3 of the logic circuit 20, the contact B is at the DC power supply Vcc, and the key C is TRIAC. It is connected to the gate G of each. The T1 point of the TRIAC is connected to the AC power input terminal and grounded, and the T2 point is connected to the AC power output terminal 4.
이와같은 구조된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention structured as follows.
오전5시에 예약취사를 하고자 할 경우, 논리회로(20)의 시각선택스위치A에 접속시켜둔다. 시간이 경과하여 오전5시가 되면, 시단위표시부(10)의 'b'세그먼트 출력단과, 'e'세그먼트 출력단은 모두 저전위가 되고 이 저전위들은 인버터(1), (2)에 의해 고전위로 반전되어 엔드 게이트(3)에 입력된다. 또, 오전표시출력단 역시 오전5시에는 고전위로, 엔드게이트(3)의 세입력은 모두 고전위로 입력되어진다.If reservation is to be made at 5 am, the time is selected to the time selection switch A of the logic circuit 20. When the time elapses and reaches 5 am, both the 'b' segment output terminal and the 'e' segment output terminal of the time display unit 10 become low potentials, and these low potentials become high potentials by the inverters (1) and (2). It is inverted and input to the end gate 3. The morning display output stage is also input at high potential at 5 am, and all three inputs of the end gate 3 are input at high potential.
따라서 엔드 게이트(3)의 출력은 고전위가 되고, 그 고전위출력은 예약취사선택스위치(S. W. 2)의 접점 A키C를 통해 트라이악(TRIAC)의 게이트(G)에 가해져 트라이악(TRIAC)을 도통시킨다. 트라이악(TRIAC)이 도통되면 교류전원출력단(4)에 교류전원이 공급되어 취사가 시작되는 것이다.Therefore, the output of the end gate 3 becomes a high potential, and the high potential output is applied to the gate G of the triac through the contact A key C of the reservation selection switch SW 2 so that the triac is triac. Turn on). When the triac (TRIAC) is turned on, AC power is supplied to the AC power output terminal 4 to start cooking.
다시 시간이 경과하여 오전6시가 되면, 시단위표시부(10)의 'b'세그먼트출력단은 저전위 그대로이나, 'e'세그멘트 출력단은 고전위가 된다.When the time elapses again to 6 am, the 'b' segment output terminal of the time display unit 10 remains low potential, but the 'e' segment output terminal becomes high potential.
따라서 인버터(2)에는 고전위가 입력되어 그 출력은 저전위로 반전한다.Therefore, a high potential is input to the inverter 2 and its output is inverted to a low potential.
엔드 게이트(3)의 출력 역시 인버터(2)의 저전위출력이 입력되어 저전위로 반전한다. 그로인해 트라이악(TRIAC)은 불통되어 교류전원출력단(4)에 교류전원공급인 차단되어 취사가 종료된다.The output of the end gate 3 is also inverted to a low potential by inputting the low potential output of the inverter 2. As a result, the triac TRIAC is rejected, the AC power supply is cut off to the AC power output stage 4, and cooking is terminated.
오전 6시에 예약취사를 할 경우에는, 시각선택스위치(S. W. 1)을 ON시키 시단위표시부(10)의 'e'세그멘트출력단이 직접엔드 게이트(3)의 입력단에 접속되게 하는 것과, 취사종료시각이 오전 7시가 된 점만 상이할 뿐, 상기한 오전 5시 예약취사의 경우와 동일하게 작용하므로 그 설명은 생략한다.In the case of reservation cooking at 6 am, turn on the time selector switch (SW 1) so that the 'e' segment output terminal of the time display unit 10 is directly connected to the input terminal of the end gate 3; Only the point in time becomes 7:00 AM, and the same operation as in the case of the 5 AM reservation above, the description thereof will be omitted.
예약취사선택스위치(S. W. 2)의 키C를 접점B에 접속시키면, 직류공급전원 Vcc가 트라이악(TRAIC)의 게이트(G)에 직접가해져 트라이악(TRAIC)이 도통, 취사가 이루어지는 것으로써 사용자가 임의 시각에 취사를 하고자 할 때에 사용하는 것이다.When the key C of the reservation cooking selection switch SW 2 is connected to the contact point B, the DC power supply Vcc is directly applied to the gate G of the triac TRAIC so that the triac is turned on and cooked. Is used to cook at any time.
상술한 바와같이 본 고안은 전기밥솥으로 예약취사를 행함에 있어 종래의 예약취사전기밥솥들과는 달리, 매일 예약취사시각을 계산 설정해야하는 불편이 없이, 예약하는 싯점이 언제이든 매일 일정한 시간의 예약취사가 가능케되는 대단히 편리하고, 유용한 점이 있는 것이다.As described above, the present invention, unlike the conventional reservation cooking electric rice cookers in the reservation cooking with the electric rice cooker, without the inconvenience of having to calculate and set the daily reservation cooking time, the reservation point of the reservation at any time every day There is a lot of convenience and usefulness that is possible.
또 부수적으로 취사장소에서 항시 시각을 확인할 수 있는 점도 있다.As a side note, you can always check the time at the kitchen.
본 고안의 요지를 벗어나지 아니한 범위내에서의 변경, 즉 증폭기능의 첨설, 오전 오후 전환스윗치의 첨설, 트라이악(TRIAC)의 게이트(G)에 한류저항의 삽입등이 가능함은 주지의 사실이다.It is well known that modifications within the scope not departing from the gist of the present invention, that is, the addition of the amplifier function, the addition of the switching switch in the morning and the afternoon, the insertion of the current-limiting resistor into the gate G of the TRIAC.
