본 발명은 포량감지 세탁기의 예약세제 투입장치와 방법에 관한 것으로, 특히 예약세탁시 홀소자에 의한 즉각적인 포량센싱으로 수위 및 세제량을 결정하여 표시해주므로서 사용자에게 적절한 세제량을 투입할 수 있도록한 것이다.The present invention relates to a reservation detergent input device and method of the laundry detection washing machine, and in particular, it is possible to input the appropriate detergent amount to the user by determining and displaying the water level and the detergent amount by the instant amount sensing by the hall element during the reservation laundry.

종래 세탁기는 제1도에 도시된 바와같이 세탁모터(1)의 잔류 회전속도 변환에 의해 포량을 감지하는 포량센서부(2)와, 상기 모터(1)의 양단에서 발생하는 역기전력에 의해 온/오프 작동하는 포토트랜지스터(3)와, 포토트랜지스터(3)의 온/오프에 의해 포량센서부(2)에서 감지한 포량신호를 파형 정형하는 파형정형 회로부(4)와, 정형된 파형신호에 의해 포량을 판단하여 세탁기를 제어하는 마이컴(5)으로 구성된 것으로, 미설명부호 R1 내지 R6은 저항, Q1, Q2는 트랜지스터, D1, D2는 다이오드이다.In the conventional washing machine, as shown in FIG. 1, the washing machine is turned on / off by the quantity sensor unit 2 for detecting the quantity by the residual rotational speed of the washing motor 1 and the counter electromotive force generated at both ends of the motor 1. The phototransistor 3 which is turned off, the waveform shaping circuit section 4 for waveform shaping the amount of signal detected by the quantity sensor section 2 by the on / off of the phototransistor 3, and the shaped waveform signal. It is composed of a microcomputer (5) for controlling the washing machine by judging the quantity, the reference numeral R1 to R6 is a resistor, Q1, Q2 is a transistor, D1, D2 is a diode.

이와같이 구성된 종래 세탁기의 세탁 예약방법은 제1도와 제2도에 도시된 바와같이, 먼저 사용자가 세탁조내에 투입된 세탁물에 예약세제을 할 것인지 판단한다. 판단결과 예약세탁이 설정되지 않았으면 일반세탁을 수행하도록 하며, 예약세탁을 설정하였으면 세탁기가 예약동작을 시작하며, 이때 세탁물을 세탁하기 위해 사용자가 임의로 세제를 적당량 짐작하여 투입한다.In the laundry reservation method of the conventional washing machine configured as described above, as shown in FIG. 1 and FIG. 2, the user first determines whether to make a reservation detergent for laundry put in the washing tank. As a result of the determination, if the laundry is not set, general washing is performed. If the washing is set, the washing machine starts a reservation operation. At this time, the user arbitrarily guesses an appropriate amount of detergent to wash the laundry.

이후 일정기간 경과후 예약세탁시간에 도달하여 세탁기가 동작하는지 판단한다. 판단결과 예약세탁시간에 도달하지 않았으면 현재 세탁기에 예약중임을 표시되면서 세탁기는 정지된 상태를 유지하며 일정시간 경과후 예약세탁시간에 도달하였으면 마이컴(5)은 이를 감지하여 세탁조내에 급수를 진행한다.After a certain period of time after the reservation laundry time is reached to determine whether the washing machine operates. If it is determined that the reservation washing time has not been reached, the washing machine is in the stopped state while indicating that the washing machine is currently being reserved. If the reservation washing time is reached after a predetermined time, the microcomputer 5 detects this and proceeds with water supply in the washing tank. .

이때 급수된 수위가 최소 수위에 도달하였는지 판단한 결과 최소 수위에 도달하였으면 모터(1)를 좌, 우반전을 시작하여 포량센서부(2)에 세탁 물량에 따른 포량을 감지하고 세탁할 수위를 결정한다.At this time, when it is determined whether the water level reaches the minimum level, when the minimum level is reached, the motor 1 starts to be reversed to the left and right, and the quantity sensor unit 2 detects the quantity according to the quantity of laundry and determines the level of washing. .

즉, 세탁모터(1)의 좌/우반전에 따른 잔류 회전력에 의해 역기전력이 발생되고 이 역기전력이 포량센서부(2)에서 포토트랜지스터(3)를 온/오프시켜 감지한 포량감지 신호가 파형정형 회로부(4)를 통해 정형된 신호로 출력되어 마이컴(5)에 공급되므로서 포량을 감지하고 감지된 포량으로 세탁수위를 결정하여 세탁기가 세탁을 진행한다.That is, the counter electromotive force is generated by the residual rotational force according to the left / right inversion of the washing motor 1, and the counter electromotive force is detected by the on / off detection of the phototransistor 3 by the capacity sensor unit 2. The washing machine performs the washing by outputting the signal through the circuit unit 4 and supplying it to the microcomputer 5 to detect the quantity of water and determine the washing level with the detected quantity.

그러나 종래 세탁기는 세탁예약시, 세탁물의 양에 따른 적절한 세제투입이 되지 못하고 사용자가 임의로 판단하여 세제를 투입하므로서 세탁물량에 맞게 세제를 투입하지 못하여 사용자에 따라 세제를 낭비하는 문제점이 있었다.However, in the conventional washing machine, there is a problem in that the washing machine cannot waste the detergent according to the amount of laundry because the user cannot arbitrarily put detergent according to the amount of laundry, and the user inputs the detergent at random.

본 발명은 이와같은 종래 문제점을 해결하기 위하여 예약세탁시 홀소자에 의한 즉각적인 포량 센싱으로 수위 및 세제량을 결정하여 세제표시부에 세제투입량을 표시하므로서 사용자가 세탁물량에 맞는 세제를 투입하도록 하는데 그 목적이 있는 것으로 첨부된 도면에 의하여 본 발명의 구성 및 작용효과를 설명하면 다음과 같다.The present invention is to solve the conventional problems by determining the water level and the amount of detergent by the instant amount sensing by the hall element during the reservation laundry to display the amount of detergent in the detergent display unit so that the user inputs detergent suitable for the amount of laundry Referring to the configuration and effect of the present invention by the accompanying drawings as follows.

먼저, 본 발명 세탁기는 제3도에 도시된 바와같이, 세탁모터(11)를 지지하는 회전축(12)에 체결된 다극마그네트(13)와, 상기 다극마그네트(13)와 대향되어 모터(11)의 회전속도를 감지하는 홀소자(14)와, 홀소자(14)에 의해 감지된 모터(11)의 잔류 회전속도에 따라 포량을 감지하는 포량센서부(15)와, 감지된 포량신호를 파형정형하는 파형정형 회로부(16)와, 정형된 감지신호에 의해 포량을 감지하여 세탁기를 제어하는 마이컴(17)과, 마이컴(17)의 제어신호에 의해 세탁 물량에 따른 세제량을 표시하는 세제표시부(18)로 구성된 것으로, 미설명부호 R7 내지 R10은 저항, Q3은 트랜지스터, D3은 다이오드, C1, C2는 콘덴서, S1 내지 S8은 LED이다.First, as shown in FIG. 3, the washing machine of the present invention is opposed to the multipole magnet 13 fastened to the rotating shaft 12 supporting the washing motor 11 and the multipole magnet 13 so as to face the motor 11. Hall element 14 for detecting the rotational speed of the sensor, the quantity sensor unit 15 for detecting the amount of air in accordance with the remaining rotational speed of the motor 11 detected by the hall element 14, and the detected amount of waveform signal The waveform shaping circuit unit 16 for shaping, the microcomputer 17 for controlling a washing machine by sensing a quantity by the shaped detection signal, and the detergent display unit for displaying the amount of detergent according to the amount of laundry by the control signal of the microcomputer 17 ( 18), reference numerals R7 to R10 are resistors, Q3 is a transistor, D3 is a diode, C1 and C2 are capacitors, and S1 to S8 are LEDs.

이와같이 구성된 본 발명의 작용효과는 제3도와 제4도에 도시된 바와같이, 먼저 사용자가 세탁조내에 세탁물을 투입한 후 예약세탁을 할것인지 판단한다.As shown in FIG. 3 and FIG. 4, the operation effect of the present invention configured as described above determines whether the user will put the laundry into the washing tank and then perform the scheduled washing.

판단결과 예약세탁이 설정되지 않았으면 일반동작으로 세탁진행을 수행하며, 예약세탁이 설정되었으면 세탁기를 제어하는 마이컴(17)에 의해 세탁모터(11)를 반전 구동시켜준다. 이때 모터(11)를 지지하는 회전축(12)에 체결된 다극마그네트(13)에 대향되게 위치한 홀소자(14)가 상기 모터(11)회전시 다극마그네트(13)에서 변화된 자속을 전기적인 신호로 감지한다. 감지된 홀소자(14)의 출력신호가 포량센서부(15)에 입력되어 세탁기의 포량을 감지한 소저전압과 파형의 감지신호를 출력한다.As a result of the determination, if the reserved laundry is not set, the washing process is performed in a normal operation. If the reserved washing is set, the washing motor 11 is reversely driven by the microcomputer 17 controlling the washing machine. At this time, when the hall element 14 located opposite to the multipole magnet 13 fastened to the rotating shaft 12 supporting the motor 11 rotates the motor 11, the magnetic flux changed by the multipole magnet 13 is an electrical signal. Detect. The detected output signal of the Hall element 14 is input to the quantity sensor unit 15 and outputs a sensed voltage and a waveform detection signal for detecting the quantity of the washing machine.

즉, 다극마그네트(13)의 자극변화에 따른 전압변동이 포량센서부(15)에 의해 제5a도에서와 같이 출력단(A)을 통해 출력된다.That is, the voltage fluctuation according to the change in the magnetic pole of the multi-pole magnet 13 is output through the output terminal A as shown in FIG. 5A by the dose sensor unit 15.

출력된 파형은 파형정형 회로부(16)에 인가되어 트랜지스터(Q3)에 의해 반전 증폭된 후, 마이컴(17)의 입력단(B)을 통해 제5b도와 같은 파형이 인가된다.The output waveform is applied to the waveform shaping circuit unit 16 and inverted and amplified by the transistor Q3, and then the waveform shown in FIG. 5B is applied through the input terminal B of the microcomputer 17.

따라서 마이컴(17)은 파형정형 회로부(16)에서 출력된 파형의 갯수 및 주기에 따라 세탁모터(11)의 잔류회전력을 인식하여 포량을 판단하고 그 결과에 따라 세탁수위를 결정하고, 세제표시부(18)의 LED(S1 내지 S8)에 세탁물량 및 수위에 맞는 세제량을 자동 표시한다.Therefore, the microcomputer 17 recognizes the residual rotational power of the washing motor 11 according to the number and period of the waveform output from the waveform shaping circuit unit 16 to determine the quantity of the laundry and determines the washing level according to the result. The LEDs S1 to S8 of 18) automatically display the amount of detergent suitable for the laundry amount and the water level.

즉, 세탁물량에 따라 LED(S1-S8)를 비례적으로 점등시켜 준다.That is, the LED (S1-S8) is lit proportionally according to the amount of laundry.

이후, 사용자는 세제표시부(18)의 LED(S1 내지 S8)에 표시된 세제량에 따라 세제를 세탁조내에 투입하여 예약동작을 수행하도록 하는 것이다.After that, the user inputs the detergent into the washing tank according to the amount of detergent displayed on the LEDs S1 to S8 of the detergent display unit 18 to perform the reservation operation.

이상에서 설명한 바와같이 다극마그네이트와 대향되게 구비된 홀소자에 의해 세탁조내에 급수하지 않고 마른포(마른옷감)상태에서 즉각적으로 포량을 감지하여 수위 및 세제량을 자동으로 결정하므로서 세제투입량을 세제표시부에 표시하여 사용자가 예약세탁시 세제표시부에 표시된 세제량을 세탁조내에 투입하므로서 세제 낭비없이 세탁량에 맞는 세제를 투입할 수 있는 효과가 있다.As described above, the amount of detergent is automatically added to the detergent display by automatically detecting the amount of water in the dry cloth (dry cloth) and automatically determining the water level and the amount of detergent, without supplying water into the washing tank by the hall element provided to face the multi-pole magnet. When the user displays the laundry, the detergent amount displayed on the detergent display unit is put into the washing tank, so that the detergent can be put in the washing amount without waste of detergent.
