본 발명에 따른 드럼세탁기는 도 2에 도시된 바와 같이, 사용자 요구명령을 입력하기 위한 키 입력부(101)와, 상기 키 입력부(101)를 통해 동작시작 명령이 입력되면 모터(106)를 구동시키고, 모터(106)가 기 설정된 회수까지 회전되는 시간(t1)을 감지한 후 다시 모터(106)를 정지시켜 완전히 정지할 때까지의 시간(t2)을 감지하여 그 값에 따라 포량을 파악하고 해당 세탁패턴을 결정하여 제어신호를 출력하는 마이컴(105)과, 상기 마이컴(105)의 제어신호에 따라 급수를 수행하면서 터브(도시생략)내의 수위를 감지하는 수위감지부(103)와, 온도를 감지하기 위한 온도 감지부(104)와, 상기 마이컴(105)의 제어신호에 따라 상기 모터(106)를 구동시키는 모터 구동부(107)와, 상기 마이컴(105)의 제어신호에 따라 히터(108)를 구동시키는 히터 구동부(109)와, 상기 마이컴(105)등 내부에 전원을 공급하기 위한 전원부(102)로 구성된다.As shown in FIG. 2, the drum washing machine according to the present invention drives a motor 106 when a key input unit 101 for inputting a user request command and an operation start command are input through the key input unit 101. After detecting the time t1 at which the motor 106 is rotated up to a preset number of times, the motor 106 is stopped again to detect the time t2 until the motor stops completely, and the quantity is determined according to the value. A microcomputer 105 for determining a washing pattern and outputting a control signal, a water level detecting unit 103 for detecting a water level in a tub (not shown) while supplying water according to the control signal of the microcomputer 105, and a temperature; The heater 108 according to the temperature sensing unit 104 for sensing, the motor driving unit 107 for driving the motor 106 according to the control signal of the microcomputer 105, and the control signal of the microcomputer 105. Heater drive unit 109 for driving the inside, the microcomputer 105 and the like It is composed of a power supply unit 102 for supplying power to the unit.

이와 같이 구성된 본 발명에 따른 드럼세탁기는 사용자가 상기 키 입력부(101)를 통해 동작시작 명령을 입력하면, 급수를 수행하기 이전에 포량 감지를 먼저 실시한다.When the drum washing machine according to the present invention configured as described above inputs an operation start command through the key input unit 101, a quantity of water is first detected before performing water supply.

이때 실시되는 포량 감지는 상기 모터(106)를 기 설정한 일정 회수까지 회전시키고, 그때까지의 소요시간(t1)을 감지한 후 다시 모터(106)를 정지시켜 모터(106)가 완전히 정지될 때까지의 소요시간(t2)을 감지한다.The quantity detection carried out at this time rotates the motor 106 to a predetermined number of times, detects the required time t1 until then, stops the motor 106 again, and when the motor 106 is completely stopped. Detect the time required until t2.

이때 소요시간(t1)(t2)은 도 4에 도시된 바와 같이, 포량에 따른 일정 회전수 도달시간(t1)은 포량이 증가함에 따라 서서히 증가하다가 일정포량 이상이 되면 거의 동일한 시간이 소요됨을 알 수 있다.In this case, as shown in FIG. 4, the required time t1 (t2) reaches a predetermined rotational speed t1 depending on the amount of the gun and gradually increases as the amount of the gun increases. Can be.

한편 포량에 다른 모터(106)의 정지시간은 도 4에 도시된 바와 같이, 포량이 작으면 소요시간이 그만큼 짧게 걸기고, 포량이 많으면 소요시간이 많이 걸리므로 포량에 따라 정지까지의 시간은 많은 차이를 나타냄을 알 수 있다.On the other hand, as shown in FIG. 4, the stopping time of the other motor 106 is smaller than the amount of time required. If the amount of time is small, the time required for stopping is large. It can be seen that there is a difference.

그리고, 상기 감지된 소요시간(t1)(t2)을 소정의 산출식에 적용하여, 그 산출결과에 따라 포량을 파악하며, 상기 소정의 산출 식은 다음 식과 같다.Then, the detected required time t1 (t2) is applied to a predetermined calculation formula, and the quantity is determined according to the calculation result, and the predetermined calculation formula is as follows.

즉, 상기 소요시간(t1)(t2)을 상기 수학식에 적용하고, 그 산출 값에 따라 포량이 많고 적음을 판단하게 되는데, 이때 산출 값과 포량은 비례한다.That is, the required time (t1) (t2) is applied to the above equation, and it is determined that the quantity is large and small according to the calculated value, wherein the calculated value and the quantity are proportional.

이와 같이 구성된 본 발명에 따른 드럼세탁기의 포량감지 방법을 도 3을 참조하여 설명하면 먼저, 파워 온이 되면 사용자가 동작시작 명령을 입력하였는지 여부를 파악한다(S11∼S12).Referring to FIG. 3, the drum washing machine according to the present invention configured as described above will be described with reference to FIG. 3. First, when the power is turned on, a user inputs an operation start command (S11 to S12).

이어서 상기 판단 결과(S12), 사용자가 동작시작 명령을 입력하면 상기 모터(106)를 기 설정한 일정회수까지 동작시키면서 그때까지의 소요시간(t1)을 측정한다(S13).Subsequently, when the user inputs an operation start command, the determination result S12 measures the required time t1 until the motor 106 is operated up to a predetermined number of times (S13).

또한 상기 일정회수까지 동작이 되었으면, 또한 상기 모터의 구동을 중단시키고 모터가 정지될 때까지의 소요시간(t2)을 측정한다(S14).In addition, when the operation is performed up to the predetermined number of times, the driving time of the motor is stopped and the required time t2 until the motor is stopped is measured (S14).

그리고 상기 측정된 소요시간(t1)(t2)을 소정의 산출 식에 적용하고, 그 산출결과에 따라 포량을 파악한다(S15).Then, the measured required time t1 (t2) is applied to a predetermined calculation formula, and the amount of storage is grasped according to the calculation result (S15).

상기 포량이 파악되면 해당 포량에 따라 급수 량이 결정되고, 그에 따라 급수를 수행한다(S16). If the quantity is determined, the water supply amount is determined according to the corresponding quantity, and water supply is performed accordingly (S16).

이어서 상기 급수가 완료되었는지 여부를 판단한다(S17).Next, it is determined whether the water supply is completed (S17).

상기 판단 결과(S17), 급수가 완료되었으면 이후 설정된 세탁패턴에 따라 해당 세탁행정을 수행한다(S18).As a result of the determination (S17), when the water supply is completed, the washing administration is performed according to the set washing pattern (S18).

그리고 모든 세탁이 완료되면 종료한다(S19).And when all the washing is completed (S19).

따라서, 본 발명에 따른 드럼세탁기 및 그 포량 감지방법은 종래의 방법과는 달리, 사용자가 동작시작명령을 입력하면 급수를 수행하기 이전에 포량감지를 실시하고, 포량이 감지되면 해당 포량에 따른 급수량이 결정되어 급수가 이루어진다.Therefore, unlike the conventional method, the drum washing machine and its quantity detecting method according to the present invention, when the user inputs an operation start command, performs a quantity detection before performing the water supply, and when the quantity is detected, the water supply amount according to the corresponding quantity This is determined and water supply is made.

이상에서 설명한 바와 같이 본 발명에 따른 드럼세탁기 및 그 포량감지방법은 다음과 같은 효과가 있다.As described above, the drum washing machine and the quantity detection method according to the present invention have the following effects.

첫째, 포량을 먼저 감지한 후 급수량이 결정됨에 따라 포질과 상관없이 정확한 포량이 파악될 수 있다.First, since the amount of water is first detected and then the amount of water is determined, the correct amount of water can be identified regardless of the quality of the water.

둘째, 포량 파악이 정확하게 이루어짐에 따라 급수량, 세탁시간 등의 세탁패턴이 적절하게 설정될 수 있으므로 세탁성능을 향상시킬 수 있다.Second, as the grasping of the amount is accurately made, washing patterns such as water supply and washing time can be appropriately set, thereby improving washing performance.

셋째, 세탁성능이 향상됨에 따라 사용자의 제품사용에 따른 만족도도 향상시킬 수 있다.Third, as the washing performance is improved, the user's satisfaction with using the product may be improved.
