Abstract

An apparatus for controlling a heater of a toaster is provided to reduce a power and extend a life span of a heater by only driving a heater into which bread is inserted. Heater driving units(32,33) are connected to heaters(H1,H2) separately. A light emitting elements(PT1,PT2) radiates beams(B1,B2) to penetrate bread insertion holes(46,48) through penetration holes(50,52) formed on the heaters(H1,H2). Receiving elements(PD1,PD2) detect an insertion of a bread by detecting a shield of beams which penetrate the bread insertion holes(46,48). An oven switch(SW) switches a heater driving. Indicating lamps(L1,L2) indicate which heaters(H1,H2) are driving. A control unit(30) controls a heater(H1) where a shield is detected from the receiving elements(PD1, PD2) when the limit switch(LS) and the oven switch(SW) are turned on. The control unit(30) controls the indicating lamps(L1,L2) corresponding to heaters(H1,H2) to be flickered for a driving time.

이하 본 발명에 따른 작용을 첨부도면에 의거하여 상세히 설명한다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도1 내지 도3에 도시된 바와 같이 토스터기 본체(40)에 형성된 빵투입구(46)(48) 중 한쪽에 빵을 투입한 다음 이젝트레버(42)를 누르게 되면, 빵이 빵투입구(46)(48)로 깊숙하게 진입되고 동시에 토스터기 본체(40)에 내장된 리미트스위치(LS)가 이젝트레버(42)에 의해 눌려 접점이 닫히면서 "ON"상태로 전환된다.1 to 3, when the bread is put into one of the bread inlets 46 and 48 formed in the toaster main body 40, and then the eject lever 42 is pressed, the bread is the bread inlet 46 (48) is deeply entered and at the same time the limit switch LS built in the toaster main body 40 is pressed by the eject lever 42 to close the contact is switched to the "ON" state.

이후 타이머(31)의 다이얼을 돌려서 히터구동시간을 설정한 다음 토스터기 본체(40)에 설치되어 있는 오븐스위치(SW)를 누르게 되면, 제어부(30)는 도3의 단계 S10,S12,S14에서 리미트스위치(LS)와 오븐스위치(SW), 타이머(31)가 모두 "ON"으로 설정되어 있는지의 여부를 판정하여 히터(H1)(H2)를 구동하게 되는데, 이때 리미트스위치(LS)와 오븐스위치(SW), 타이머(31) 중 어느 하나라도 "OFF"상태인 것으로 판정되면, 히터(H1)(H2) 구동을 멈추게 되며, 모두 "ON"인 것으로 판정되면, 빵이 투입된 히터(H1)(H2)만 구동하게 된다.After setting the heater driving time by turning the dial of the timer 31, and then pressing the oven switch (SW) installed in the toaster main body 40, the control unit 30 limits in steps S10, S12, S14 of FIG. It is determined whether the switch LS, the oven switch SW, and the timer 31 are all set to "ON" to drive the heaters H1 and H2. At this time, the limit switch LS and the oven switch are driven. (SW) If any one of the timers 31 is determined to be in the " OFF " state, the driving of the heaters H1 and H2 is stopped, and if all are determined to be " ON, " Only H2) will be driven.

즉, 제어부(30)는 도3의 단계 S10,S12,S14에서 리미트스위치(LS)와 오븐스위치(SW), 타이머(31)가 모두 "ON"인 것으로 판정되면, 출력포트에 접속되어 있는 발광소자(PT1)(PT2)를 구동하여 점등시키게 되는데, 이때 빵투입구(46)(48)에 빵이 투입된 경우에는 발광소자(PT1)(PT2)로부터 방사되는 빔(B1)(B2)이 차광되어 수광소자(PD1)(PD2)가 "OFF"상태로 되고, 빵투입구(46)(48)에 빵이 투입되어 있지 않은 경우에는 발광소자(PT1)(PT2)로부터 방사되는 빔(B1)(B2)이 관통구멍(50)(52)을 통해 빵투입구(46)(48)를 가로질러서 수광소자(PD1)(PD2)에 입사되면서 수광소자(PD1)(PD2)가 "ON"상태로 된다.That is, when the control switch 30 determines that the limit switch LS, the oven switch SW, and the timer 31 are both "ON" in steps S10, S12, and S14 of FIG. 3, the light emission connected to the output port is determined. When the device is turned on by driving the devices PT1 and PT2, when the bread is inserted into the bread openings 46 and 48, the beams B1 and B2 emitted from the light emitting devices PT1 and PT2 are shielded. When the light receiving elements PD1 and PD2 are in the " OFF " state and no bread is put into the bread openings 46 and 48, the beams B1 and B2 radiated from the light emitting elements PT1 and PT2. Is incident on the light receiving elements PD1 and PD2 via the through holes 50 and 52, and the light receiving elements PD1 and PD2 are turned “ON”.

이때 제어부(30)는 도3의 단계 S16에서 수광소자 "PD1"의 차광여부를 검출하게 되는데, 수광소자 "PD1"이 차광된 것으로 판정되면, 토스터기 본체(40)의 빵투입구 "46"에 빵이 투입되어 있는 것으로 간주하여 단계 S18에서 히터 "H1"을 히터구동부(32)를 통해 구동하여 발열시킨 다음 단계 S20에서 해당 표시램프 "L1"를 점등하여 표시하게 된다.At this time, the control unit 30 detects whether or not the light receiving element "PD1" is shielded in step S16 of FIG. 3. If it is determined that the light receiving element "PD1" is shielded, the bread is inserted into the bread opening "46" of the toaster main body 40. In this case, the heater " H1 " is driven through the heater driver 32 to generate heat, and the corresponding display lamp " L1 " is turned on and displayed in step S20.

또한, 제어부(30)는 도3의 단계 S22에서 수광소자 "PD2"의 차광여부를 검출하게 되는데, 수광소자 "PD2"이 차광된 것으로 판정되면, 토스터기 본체(40)의 빵투입구 "48"에 빵이 투입되어 있는 것으로 간주하여 단계 S24에서 히터 "H2"를 히터구동부(33)를 통해 구동하여 발열시킨 다음 단계 S26에서 해당 표시램프 "L2"를 점등하여 표시하게 된다.In addition, the control unit 30 detects whether the light receiving element "PD2" is shielded from light in step S22 of FIG. 3. It is assumed that the bread has been put, the heater " H2 " is driven through the heater driver 33 to generate heat in step S24, and then the corresponding display lamp " L2 " is lit and displayed in step S26.

이후 제어부(30)는 도3의 단계 S28에서 타이머(31)가 설정된 시간에 도달하였는가의 여부를 주기적으로 조사하여 타이머(31)가 "OFF"상태로 전환된 경우 타이머(31) 설정시간이 경과한 것으로 간주하여 단계 S30에서 구동 중인 히터(H1)(H2)를 "OFF"상태로 전환하고, 단계 S32에서 점등 중인 표시램프(L1)(L2)를 모두 소등한 다음 단계 S34에서 빵이젝터(34)를 구동하여 빵투입구(46)(48)에 삽입되어 있던 빵을 배출하게 된다.Thereafter, the controller 30 periodically checks whether the timer 31 has reached the set time in step S28 of FIG. 3 and when the timer 31 is switched to the " OFF " state, the set time of the timer 31 has elapsed. Considering that, the heater H1 (H2) being driven is switched to the " OFF " state in step S30, and all the display lamps L1 and L2 being lit are turned off in step S32, and then the bread ejector 34 in step S34. ) To discharge the bread that has been inserted into the bread inlet (46) (48).

이상에서 설명한 바와 같은 본 발명은 두 개의 히터 중에 빵이 투입된 히터만 구동되도록 구성되어 있기 때문에 전력을 절감할 수 있을 뿐만 아니라 히터의 수명을 연장할 수 있는 효과가 있으며, 빵이 투입되어 있지 않으면 히터 구동을 멈 추기 때문에 화재로부터 안전하고, 두 개의 빵투입구 중에 한 개의 빵투입구에 빵이 투입된 경우 수광소자에 의해 투입 위치를 자동으로 판별하여 해당 히터만 구동하도록 구성되어 있기 때문에 사용이 편리하게 되는 효과가 있다.As described above, the present invention is configured to drive only the heater into which the bread is put in, so that the electric power can be reduced and the life of the heater can be extended. It is safe from fire because it stops driving, and when bread is put into one of the two bread openings, it is easy to use because it is configured to drive the heater only by automatically determining the feeding position by the light receiving element.
