Description
본 발명은 세탁기의 포량감지방법에 관한 것으로서, 특히 세탁모터의 온도변화에 관계없이 정확한 포량감지가 가능하도록 하는 세탁기의 포량감지방법에 관한 것이다.The present invention relates to a quantity detection method of a washing machine, and more particularly, to a quantity detection method of a washing machine to enable accurate quantity detection regardless of the temperature change of the washing motor.
일반적으로 세탁기는 동력 전달 방식에 따라, 세탁모터에서 발생된 동력을 클러치를 이용하여 펄세이터(Pulsator)로 전달하여 펄세이터를 회전시키는 클러치 구동방식과, 세탁모터와 세탁조를 직접 연결하여 세탁모터의 동력을 이용하여 세탁조를 직접 회전시키는 직접 구동(Direct Drive)방식으로 구분된다. 이때, 상기 클러치 구동방식은 펄세이터만을 구동하므로 세탁조 내부의 강력한 물살을 만들기 위하여 세탁모터가 고속으로 회전되어야 하기 때문에 포화 펄세이터의 마찰로 인하여 포손상이 클 뿐만 아니라 소음이 높고 세탁 및 헹굼 성능이 저하되는 문제점이 있다.In general, a washing machine is a clutch driving method for rotating a pulsator by transmitting power generated from a washing motor to a pulsator using a clutch according to a power transmission method, and directly connecting a washing motor and a washing tank to the washing motor. It is divided into direct drive method that directly rotates the washing tank by using power. At this time, since the clutch driving method drives only a pulsator, the washing motor must be rotated at a high speed in order to make a strong water inside the washing tank. There is a problem of deterioration.
상기와 같은 이유로 인해 최근 세탁기에는 직접 구동방식이 주로 적용되고 있는데, 상기 직접 구동방식의 세탁기에는 세탁모터의 고효율 및 고성능을 위하여 인버터 방식으로 구동되는 무정류자 직류모터(BLDC Motor)가 사용된다.Recently, the direct drive method is mainly applied to the washing machine for the above reasons, and the direct drive type washing machine uses a non-commutator DC motor (BLDC Motor) driven by an inverter method for high efficiency and high performance of the washing motor.
한편, 최근의 전자동 세탁기에서는 세탁행정 초기에 포량을 감지하여 그 결과에 따라 수위, 세탁시간, 세탁패턴, 탈수시간 및 기타 세탁기의 동작에 필요한 조건들을 자동으로 설정한 후 세탁행정을 위한 구동이 이루어진다.On the other hand, the recent automatic washing machine detects the quantity at the beginning of the washing cycle, and automatically sets the water level, the washing time, the washing pattern, the dehydration time, and other conditions necessary for the operation of the washing machine according to the result. .
결국, 포량감지가 정확히 이루어지지 않은 경우에는 사용수량 증가, 세탁성능 저하, 포손상 증가, 세제 잔유등의 문제점이 발생될 수 있기 때문에 포량감지 동작을 정확히 수행하는 것이 중요하다.After all, if the quantity detection is not made correctly, it is important to perform the quantity detection operation correctly, since problems such as increased use quantity, reduced washing performance, increased damage, and detergent residues may occur.
도 1 은 종래의 기술에 따른 세탁기의 포량감지방법이 도시된 순서도로써, 먼저 제 1 단계에서 세탁기의 운전이 개시되면 포량감지신호가 입력된다.(S1 참조)1 is a flowchart illustrating a method of detecting a quantity of washing machine according to the related art. First, when the operation of the washing machine is started in the first step, the quantity detecting signal is input (see S1).
제 2 단계는 상기 제 1 단계의 포량감지신호에 따라 상기 세탁모터의 고정자에 구동신호가 출력되어 상기 세탁모터의 회전자가 특정위치로 이동시킨다.(S2 참조)In the second step, a driving signal is output to the stator of the washing motor according to the quantity detection signal of the first step so that the rotor of the washing motor moves to a specific position.
제 3 단계는 상기 세탁모터의 고정자에 구동신호를 출력하여 상기 회전자가 1/2 회전이 이루어지도록 한다.(S3 참조)The third step outputs a drive signal to the stator of the washing motor so that the rotor is rotated 1/2 (see S3).
제 4 단계는 상기 회전자가 1/2회전이 이루어지는 동안 가속시간과 세탁모터의 온도를 측정한다.(S4 및 S5 참조)In the fourth step, the acceleration time and the temperature of the washing motor are measured while the rotor is rotated 1/2 (see S4 and S5).
마지막으로, 상기 제 4 단계에서 측정된 가속시간과 온도에 따라 상기 세탁기의 포량을 산출하게 된다.(S6 참조)Finally, the quantity of the washing machine is calculated according to the acceleration time and the temperature measured in the fourth step (see S6).
그러나, 상기와 같은 종래의 기술에 따른 세탁기의 포량감지방법은 온도에 따라 상기 회전자의 가속시간이 변화될 수 있기 때문에 정확한 포량을 산출하는데 문제점이 있다.However, the quantity detection method of the washing machine according to the prior art as described above has a problem in calculating the correct quantity because the acceleration time of the rotor can be changed according to the temperature.
본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 그 목적은 세탁모터의 온도변화에 무관하게 정확한 포량을 산출하여 세탁성능이 향상되도록 하는 세탁기의 포량감지방법을 제공하는데 있다.The present invention has been made to solve the above problems of the prior art, an object of the present invention is to provide a quantity detection method of a washing machine to improve the washing performance by calculating the correct amount irrespective of the temperature change of the washing motor.
도 1 은 종래의 기술에 따른 세탁기의 포량감지방법이 도시된 순서도,1 is a flow chart illustrating a quantity detection method of a washing machine according to the prior art,
도2 는 본 발명에 따른 세탁기의 포량감지방법이 도시된 순서도이다.2 is a flowchart illustrating a quantity detection method of a washing machine according to the present invention.
상기한 과제를 해결하기 위한 본 발명에 따른 세탁기의 포량감지방법의 특징에 따르면, 포량감지신호가 입력되면 세탁모터의 고정자에 구동신호를 출력하여 회전자를 특정위치로 회전시키는 제 1 단계와, 상기 회전자가 설정시간동안 회전할 수 있도록 상기 고정자에 일정한 구동신호를 출력하는 제 2 단계와, 상기 설정시간 경과후 상기 세탁모터의 속도 및 온도를 측정하여 포량을 산출하는 제 3 단계로 이루어진다.According to a feature of the quantity detection method of the washing machine according to the present invention for solving the above problems, the first step of rotating the rotor to a specific position by outputting a drive signal to the stator of the washing motor when the quantity detection signal is input, And a second step of outputting a constant driving signal to the stator so that the rotor can rotate for a set time, and a third step of calculating a quantity by measuring the speed and temperature of the washing motor after the set time has elapsed.
이하, 본 발명에 따른 세탁기의 포량감지방법의 실시 예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, an embodiment of a quantity detection method of a washing machine according to the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 세탁기의 포량감지방법은 도 2 에 도시된 바와 같이, 먼저 제 1 단계에서 세탁기의 운전이 개시되면 포량감지신호가 입력된다.(S11 참조)In the method of detecting a quantity of washing machine according to the present invention, as shown in FIG. 2, when the operation of the washing machine is started in the first step, the quantity detecting signal is input.
제 2 단계는 상기 제 1 단계의 포량감지신호에 따라 세탁모터의 고정자에 구동신호를 출력하여 상기 세탁모터의 회전자를 특정 위치로 이동시킨다.(S12 참조)The second step outputs a drive signal to the stator of the washing motor according to the quantity detection signal of the first step to move the rotor of the washing motor to a specific position.
여기서, 상기 회전자가 상기 특정 위치로 이동된 후에는 상기 고정자로 출력되는 구동신호를 차단하여 상기 회전자가 정지상태를 유지할 수 있도록 함으로써, 상기 회전자의 초기위치를 결정하게 되는 것이다.Here, after the rotor is moved to the specific position by blocking the drive signal output to the stator to enable the rotor to remain stationary, it is to determine the initial position of the rotor.
이때, 상기 세탁모터에는 홀센서 및 온도센서등이 설치되는데, 상기 홀센서는 상기 세탁모터의 회전속도 및 회전방향과 상기 회전자의 위치를 감지하게 되고, 상기 온도센서는 상기 회전자가 회전함에 따라 발생되는 온도를 감지하게 된다.At this time, the washing motor is provided with a hall sensor and a temperature sensor, the hall sensor detects the rotational speed and rotation direction of the washing motor and the position of the rotor, the temperature sensor is rotated as the rotor rotates. Sensing the generated temperature.
또한, 상기 세탁기는 상기 홀센서 및 온도센서의 출력신호에 따라 상기 세탁모터로 출력되는 구동신호를 제어하는 마이컴이 설치된다.In addition, the washing machine is provided with a microcomputer for controlling the drive signal output to the washing motor in accordance with the output signal of the hall sensor and the temperature sensor.
제 3 단계는 상기 제 2 단계에서 상기 특정 위치로 이동된 상기 세탁모터의 회전자가 상기 고정자로 상기 일정한 크기의 구동신호가 출력되면서 회전하게 된다.(S13 참조)In the third step, the rotor of the washing motor moved to the specific position in the second step is rotated while the driving signal of the predetermined size is output to the stator.
제 4 단계는 상기 제 3 단계에서 상기 회전자가 설정시간동안 회전한 후 상기 세탁모터의 회전속도가 상기 홀센서에 의해 감지된다.(S14 참조)In the fourth step, after the rotor rotates for a predetermined time in the third step, the rotation speed of the washing motor is sensed by the hall sensor (see S14).
다시 말해서, 상기 고정자에 일정한 크기를 가지는 구동신호가 출력될 경우상기 회전자는 일정한 회전속도를 가지며 회전하게 되나, 포량에 따라 그 회전 속도가 변화하게 되므로 상기 포량을 상기 회전자의 회전속도에 따라 감지할 수 있게 되는 것이다.In other words, when a drive signal having a constant magnitude is output to the stator, the rotor rotates with a constant rotational speed, but since the rotational speed is changed according to the quantity of discharge, the amount of detection is detected according to the rotational speed of the rotor. You can do it.
제 5 단계는 상기 제 4 단계에서 상기 세탁모터의 회전자가 설정시간 동안 회전한 후의 온도를 상기 온도센서에서 감지하게 된다.(S15 참조)In the fifth step, the temperature sensor detects the temperature after the rotor of the washing motor rotates for a predetermined time in the fourth step.
마지막으로, 상기 제 4 단계 및 제 5 단계에서 감지된 상기 회전자의 회전속도와 상기 세탁모터의 온도를 통해 상기 포량을 산출하게 된다.(S16 참조)Finally, the quantity is calculated through the rotational speed of the rotor and the temperature of the washing motor detected in the fourth and fifth steps (see S16).
이때, 상기 마이컴에는 상기 세탁모터의 회전속도 및 온도에 따른 포량의 산출데이터가 미리 저장되어 상기 제 4 단계 및 제 5 단계에서 감지된 회전 속도 및 온도에 대응되는 포량을 산출해낼 수 있게 된다.At this time, the calculation data of the amount of storage according to the rotational speed and the temperature of the washing motor is stored in advance in the micom to calculate the amount corresponding to the rotational speed and temperature detected in the fourth and fifth steps.
상기와 같이 구성되는 본 발명에 따른 세탁기의 포량감지방법은 세탁모터 회전자의 회전속도가 상기 포량에 의해 변화될 수 있는 충분한 시간동안 상기 회전자를 일정한 크기의 구동신호를 통하여 회전시킴으로써, 온도변화에 무관하게 정확한 포량을 검출할 수 있기 때문에 세탁 성능을 향상시킬 수 있는 효과가 있다.The quantity detection method of the washing machine according to the present invention is configured as described above by rotating the rotor through a drive signal of a constant size for a sufficient time that the rotational speed of the washing motor rotor can be changed by the quantity, the temperature change Irrespective of the exact amount of detection can be detected, there is an effect that can improve the washing performance.
