Description

거품량 검출에 따른 세탁 제어방법{Method for controlling wash by detecting a bubble in a washer}Method for controlling wash by detecting a bubble in a washer}

본 발명은 세탁기에 관한 것으로서, 더 상세하게는 거품량 검출에 따른 세탁 제어방법에 관한 것이다.The present invention relates to a washing machine, and more particularly to a washing control method according to the amount of foam detection.

일반적으로, 세탁기는 세탁물에 묻은 때나 더러운 물질을 화학적인 분해작용과 기계적인 충격작용에 의해 제거하는 기기이다.Generally, a washing machine is a device that removes dirty or dirty substances from laundry by chemical decomposition and mechanical impact.

도 1에 도시된 바와 같이, 세탁기는 본체(1)와, 상기 본체 내에 댐퍼(5)에 의해 지지된 외조(2)와, 상기 외조 내에 회전 가능하게 설치되며 세탁물을 넣을 수 있는 원통형상의 내조(3)로 크게 나뉘어지고, 상기 내조 내에 세탁물을 세탁하기 위해 구동부(4) 에 의해 구동력이 전달된다.As shown in FIG. 1, the washing machine includes a main body 1, an outer tub 2 supported by a damper 5 in the main body, and a cylindrical inner tub rotatably installed in the outer tub to accommodate laundry. 3), the driving force is transmitted by the drive unit 4 to wash the laundry in the inner tank.

그리고 상기 구동부(4)는 로터(4a)와 스테이터(도시생략)에 의해 발생한 동력이 내조 축(3a)에 직접 전달되도록 구성된 것과, 상기 내조 축에 설치된 풀리와, 상기 외조하단 일측에 장착된 모터(도시생략)를 상호 밸트(도시생략)로 연결하여 상기 모터에 의해 발생된 동력이 상기 내조 축에 전달되도록 구성된 것과, 그 외 다양한 방법에 의해 동력이 내조축에 전달되도록 구성된 것이 있다.In addition, the driving unit 4 is configured such that power generated by the rotor 4a and the stator (not shown) is directly transmitted to the inner cylinder shaft 3a, a pulley installed on the inner cylinder shaft, and a motor mounted on one side of the outer tank lower end. (Not shown) are connected to each other by a belt (not shown), and the power generated by the motor is transmitted to the inner shaft, and the power is transmitted to the inner shaft by various other methods.

그리고 상기 세탁기는 세탁방식에 따라 상기 내조(3)가 직접 회전하면서 세탁을 수행하는 내조 구동형 세탁기와, 상기 내조는 고정된 상태로써 내조 내부 바닥면에 구비된 펄세이터(6)가 회전하면서 세탁을 수행하는 펄세이터 구동형 세탁기와, 그 외 다양한 세탁기로 구별된다.The washing machine is an inner tank driving type washing machine which directly washes the inner tank 3 according to a washing method, and the inner tank is washed while the pulsator 6 provided on the inner bottom surface of the inner tank is fixed while being rotated. The pulsator-driven washing machine to perform a, and other various washing machines are distinguished.

상기와 같이 구성된 세탁기는 다음과 같은 동작을 수행한다.The washing machine configured as described above performs the following operation.

상기 내조(3) 안으로 세탁하고자 하는 세탁물을 넣고, 세제통에 세제를 넣은 상태에서 콘트롤부에 구비된 세탁모드를 선택하면 세탁행정▶ 배수▶ 탈수행정▶ 헹굼행정▶ 배수▶ 탈수행정이 연속적으로 이루어지면서 세탁이 완료된다.Put the laundry to be washed into the inner tank (3), if you select the washing mode provided in the control unit in the state in which the detergent is put in the detergent container washing cycle ▶ drainage ▶ dehydration stroke ▶ rinsing stroke ▶ drainage ▶ dehydration stroke The laundry is complete.

즉 세탁모드가 선택되면, 급수장치가 작동하여 상기 외조(2) 내에 회전 가능하게 설치되어 있는 내조(3) 안으로 세탁에 사용될 물을 급수하고, 상기 급수된 물이 적정수위 만큼 채워지고 나면 수위센서(7)에 의해 급수는 중단됨과 동시에 구동부(4)가 정, 역 구동을 반복적으로 행한다.That is, if the washing mode is selected, the water supply device is operated to supply water to be washed into the inner tank (3) rotatably installed in the outer tank (2), the water level sensor after the water supply is filled by the appropriate level Water supply is interrupted by (7), and the drive part 4 repeatedly performs a forward and a reverse drive.

이와 같이 구동부(4)가 정, 역 구동을 행하면, 이 구동부의 구동력은 상기 내조(3) 및 내조에 구비된 세탁날개로 인가되고, 상기 구동력을 인가받은 내조 및 세탁날개가 정, 역회전함에 따라 발생되는 수류의 충격작용 및 세제의 분해작용에 의해 세탁물에 대한 세탁이 이루어지게 된다.As described above, when the driving unit 4 performs forward and reverse driving, the driving force of the driving unit is applied to the inner tub 3 and the washing blades provided in the inner tub, and the inner tub and the washing vane to which the driving force is applied are rotated forward and reverse. The washing of the laundry is performed by the impact of the water flow and decomposition of the detergent.

상기 세탁행정이 완료되고 나면, 상기 내조(3) 내의 세탁수를 배수하고 세탁물의 물기를 제거하는 탈수행정을 수행한다.After the washing administration is completed, the washing operation in the inner tank (3) is drained to perform the dehydration stroke to remove the water of the laundry.

상기 탈수행정이 완료되고 나면, 세탁행정시와 유사한 과정을 거치면서 헹굼을 수행하고, 헹굼행정이 완료되고 나면, 상기 내조(3) 내의 세탁수를 배수하고 세탁물의 물기를 제거하는 탈수행정이 다시 수행된다.After the dehydration stroke is completed, rinsing is performed while the process is similar to that in the washing stroke, and after the rinsing stroke is completed, the dehydration stroke is drained again to drain the wash water in the inner tank 3 and remove the water of the laundry again. Is performed.

상기 탈수행정이 시작되면, 상기 내조(3)가 구동부(4)에 의해 고속 회전되어 상기 내조 내에 위치한 세탁물과 그 수분에 원심력을 인가함에 따라 상기 수분은 내조 밖으로 이탈되어 상기 세탁물은 탈수된다.When the dehydration stroke is started, the inner tub 3 is rotated at a high speed by the driving unit 4 to apply centrifugal force to the laundry and its moisture located in the inner tub, so that the water is released out of the inner tub and the laundry is dewatered.

하지만 상기와 같이 이루어진 세탁기는 다음과 같은 문제점을 가지고 있다.However, the washing machine made as described above has the following problems.

상기 탈수행정이 시작되면, 세탁물과 세탁물의 잔류수분이 강한 원심력을 받게됨에 따라 상기 세탁물이 품고 있었던 거품이 빠져나오면서 상기 내조(3)와 상기 외조(2) 사이로 상기 거품이 계속적으로 생성되며 차오르게 된다.When the dehydration stroke starts, as the laundry and the residual moisture of the laundry are subjected to strong centrifugal force, the foam contained in the laundry escapes and the foam is continuously generated and filled between the inner tank 3 and the outer tank 2. do.

즉, 상기 구동부(4)에 의해 회전되는 상기 내조(3)가 상기 거품에 의해 저항을 받게되어 탈수시 원하는 내조 RPM(Revolution Per Minute)을 얻는데 문제가 있었다.That is, the inner tank 3 rotated by the driving unit 4 is subjected to resistance by the foam, and thus there is a problem in obtaining a desired inner revolution per minute (RPM) during dehydration.

또한, 상기 거품에 의한 저항으로 상기 구동부(4)에 과부하가 걸려 과열되는 문제가 있었다.In addition, there was a problem that the drive unit 4 is overloaded and overheated by the resistance caused by the foam.

따라서, 상기 문제를 해결하기 위한 발명의 필요성이 인식되었다.Thus, the necessity of the invention for solving the above problem has been recognized.

본 발명은 상기와 같은 필요성에 근거하여 안출된 것으로서, 구동부를 선택적으로 가동시켜 원활한 탈수가 이루어지도록 하는데 그 목적이 있다.The present invention has been made based on the necessity as described above, the object of the present invention is to selectively run the drive unit to achieve a smooth dehydration.

도 2에 도시된 바와 같이, 본 발명은 다음과 같은 단계를 가지고 순차적으로 진행된다.As shown in Figure 2, the present invention proceeds sequentially with the following steps.

설정된 RPM으로 내조(도4의 3참조)를 회전시켜 상기 내조 내의 거품량을 검출하는 단계와; 상기 검출결과를 설정값과 비교하는 단계와; 상기 비교결과 거품량이 설정값 이상이면 상기 내조의 회전을 정지시키고, 상기 비교결과 거품량이 설정값 이하이면 상기 내조의 RPM을 증가시키는 단계로 이루어진다.Detecting the amount of bubbles in the inner tank by rotating the inner tank (see 3 in FIG. 4) at a set RPM; Comparing the detection result with a set value; The rotation of the inner tank is stopped when the amount of foam is greater than or equal to the set value, and the RPM of the inner tank is increased when the amount of foam is less than or equal to the set value.

그리고, 최초 비교결과 거품량이 설정값 이상이면 거품량 검출 및 비교단계를 소정횟수만큼 반복한 후 내조의 회전을 정지시키는 단계와; 상기 단계 진행중 거품량이 설정량 이하이면 거품량 검출 및 비교를 중단하고 곧바로 내조의 RPM을 증가시키는 단계가 포함되어 이루어진다.And if the amount of bubbles is equal to or greater than the set value as a result of the initial comparison, stopping the rotation of the inner tank after repeating the detecting and comparing the amount of bubbles by a predetermined number of times; If the amount of foam during the step is less than the set amount comprises the step of stopping the foam amount detection and comparison and immediately increasing the RPM of the inner tank.

또한, 상기 내조의 회전이 정지되면 재급수하여 재탈수를 수행하는 단계가 더 포함되어서 이루어진다.In addition, when the rotation of the inner tank is stopped, the step of refeeding to perform the re-dehydration is further included.

상기와 같이 이루어진 본 발명은 다음과 같은 역할을 수행한다.The present invention made as described above performs the following role.

첫째, 초기탈수구간 내에서 상기 내조(도4의 3참조)의 RPM이 설정RPM 이상이면 거품량을 검출하기 시작한다(도3와 도4 참조).First, if the RPM of the inner tank (see 3 in FIG. 4) is greater than or equal to the set RPM in the initial dehydration section, the amount of foaming starts to be detected (see FIGS. 3 and 4).

둘째, 상기 검출된 거품량과 마이콤(도시생략)에 기설정된 값과 비교한다.Second, the detected amount of foam is compared with a value preset for a microcomputer (not shown).

셋째, 상기 검출된 거품량이 마이콤에 기설정된 값(이하 "설정값"이라 칭함)보다 작으면 상기 내조의 회전을 증가시켜 본 탈수를 수행시키고(도5의 1참조), 상기 검출된 거품량이 설정값보다 크면 상기 내조 내에 쌓여있는 거품의 양을 다시 검출하여 설정값과 비교한다.Third, if the detected amount of bubbles is smaller than the value preset in the microcomputer (hereinafter referred to as "set value"), the rotation of the inner tank is increased to perform this dehydration (see FIG. 5), and the amount of detected bubbles is set. If it is larger than the value, the amount of bubbles accumulated in the inner tank is detected again and compared with the set value.

그리고 상기 비교결과 거품량이 설정값보다 또 크게되면, 거품의 양을 다시 검출하여 설정값과 비교하는 단계를 반복수행한다.When the amount of bubbles is greater than the set value as a result of the comparison, the step of detecting the amount of bubbles again and comparing with the set value is repeated.

세째, 상기 단계 진행중 거품량이 설정값 이하이면 거품량 검출 및 비교를 중단하고 곧바로 내조의 RPM을 증가시켜 본 탈수로 진입시킨다.Third, if the amount of foam during the step is less than the set value, the amount of foam detection and comparison is stopped and immediately the RPM of the inner tank is increased to enter the main dehydration.

네째, 검출된 거품량과 설정값의 최초 비교 후, 상기 반복수행 단계가 소정횟수가 지남에도 불구하고 검출된 거품량이 설정값보다 크게되면 상기 내조의 회전을 정지시켜 탈수를 종료시킨다(도5의 2참조).Fourth, after the initial comparison between the detected amount of foam and the set value, if the detected amount of foam is greater than the set value despite the predetermined number of times, the rotation of the inner tank is stopped to end the dehydration (Fig. 5). 2).

그리고 상기 탈수가 종료되면, 상기 내조에 세탁수를 재급수하여 재탈수가 준비되도록 한다.When the dehydration is completed, the water is resupplied to the inner tank so that the dehydration is ready.

한편, 거품량을 검출하는 방법은, 세탁시 급수량을 제어하는 수위센서가 이용될 수도 있고, 별도의 센서가 이용될 수도 있으며, 센서가 아닌 구동부에 걸리는 부하에 의해서 상기 거품량을 검출할 수도 있다.On the other hand, as a method for detecting the amount of foam, a water level sensor for controlling the amount of water supplied during washing may be used, a separate sensor may be used, and the amount of foam may be detected by a load applied to a driving unit instead of a sensor. .

즉, 도 3과 도 4에 도시된 바와 같이, 상기 거품량을 검출하는 방법에 있어서, 수위센서(도1의 7참조)에 의한 검출방법은 다음과 같이 이루어진다.That is, as shown in Figs. 3 and 4, in the method for detecting the amount of bubbles, the detection method by the water level sensor (see 7 in Fig. 1) is performed as follows.

수위센서(7)의 주파수값을 이용하여, 상기 수위센서의 주파수값이 설정값 이하이면 거품량이 설정값보다 많은 것으로 판단하고, 상기 수위센서의 주파수값이 설정값 이상이면 거품량이 설정값보다 적은 것으로 판단하여 이루어진다.By using the frequency value of the water level sensor 7, it is determined that the bubble amount is higher than the set value if the frequency value of the water level sensor is lower than or equal to the set value. It is judged to be made.

상기와 같은 판단에 의해 본 발명에 적용되는 수위센서(7)는 다음과 같은 역할을 수행한다.The water level sensor 7 applied to the present invention by the above judgment performs the following role.

탈수행정시 초기 탈수가 진행되는 동안 세탁물에 잔류하는 세제거품 및 수분이 상기 내조(3)의 회전에 의해 계속적으로 반응하여 거품의 양이 증가하게된다(도 3참조).During the dehydration administration, the detergent and water remaining in the laundry during the initial dehydration proceed continuously by the rotation of the inner tank 3 to increase the amount of foam (see Fig. 3).

그리고 상기 거품은 원심력에 의해 내조(3)와 외조(2) 사이에 형성된 유로를 따라 계속 상승하게되는데, 이때 상기 유로에 위치한 상기 수위센서(7)의 에어챔버(7a)에도 상기 거품이 차게된다.The foam continues to rise along the flow path formed between the inner tank 3 and the outer tank 2 by centrifugal force, and the foam is also filled in the air chamber 7a of the water level sensor 7 located in the flow path. .

따라서 상기 원심력 및 세제분해작용으로 형성된 거품의 압력이 상기 수위센서(7)의 다이어프램(도시생략)으로 인가되어 상기 다이어프램이 부풀게됨에 따라 상기 수위센서의 구성요소인 코아(도시생략)와 코일보빈(도시생략)이 서로 상대변위를 일으키게된다.Therefore, the pressure of the foam formed by the centrifugal force and the detergent decomposition action is applied to the diaphragm (not shown) of the water level sensor 7 and the diaphragm is inflated, which is a core (not shown) and coil bobbin (components of the water level sensor). (Not shown) causes relative displacement with each other.

그리고 상기 상대변위에 의해 발생된 자속밀도가 높아지게되고, 그에 따라 인덕턴스값이 상승하여 결국 상기 수위센서(7)의 주파수값이 줄어들게된다(도4 참조).In addition, the magnetic flux density generated by the relative displacement is increased, thereby increasing the inductance value, thereby reducing the frequency value of the water level sensor 7 (see Fig. 4).

즉, 상기 거품의 양과 원심력이 커질수록, 상기 수위센서(7)의 주파수값이 작아지는 원리를 이용하여 탈수시 거품의 양을 검출하도록 한 것이다.That is, the greater the amount of foam and the centrifugal force, the smaller the frequency value of the water level sensor 7 is to detect the amount of foam when dewatering using the principle.

한편, 도 5에 도시된 바와 같이, 본 발명에서 기술된 상기 설정RPM은 300이고, 상기 수위센서의 주파수값과 비교되는 설정값은 26.4Hz이며, 상기 설정횟수는 100회임이 바람직하다.On the other hand, as shown in Figure 5, the set RPM described in the present invention is 300, the set value compared with the frequency value of the water level sensor is 26.4Hz, the set number is preferably 100 times.

하지만 상기 설정RPM, 설정값 그리고 설정횟수는 세탁기의 종류 및 세탁량 등에 따라 다르게 설정됨이 당연하다.However, the set RPM, the set value and the set number of times is naturally set according to the type and washing amount of the washing machine.

또한, 상기 거품량을 검출하여 세탁을 제어하는 것은 탈수시에만 한정되는것이 아니라, 필요에 따라 상기 설정RPM의 값을 변화시켜 세탁 및 헹굼시에도 적용가능함은 당연하다.In addition, controlling the washing by detecting the amount of foam is not limited only to dehydration, it is natural that the change in the value of the set RPM can be applied to washing and rinsing as necessary.

이상에서와 같이, 본 발명은 상기 구동부에 의해 회전되는 상기 내조가 상기 거품에 의한 저항을 받지 않게되어 원하는 내조 RPM을 얻을 수 있다.As described above, in the present invention, the inner tank rotated by the driving unit is not subjected to resistance by the foam, thereby obtaining a desired inner RPM.

또한, 상기 거품에 의한 저항을 받지 않게됨에 따라 상기 구동부에 과부하가 걸리는 것을 미연에 방지할 수 있어 기기의 수명을 증가시킬 수 있다.In addition, it is possible to prevent the overload of the driving unit in advance by not receiving the resistance caused by the foam, thereby increasing the life of the device.
