Description

세탁기의 헹굼수 순환장치Rinse water circulator in washing machine

본 발명은 세탁기의 헹굼장치에 관한 것으로, 특히 헹굼수를 펌핑하여 이를 정화시킨 다음 다시 재 급수 하도록 함으로써 총 세탁수의 소비량을 줄일 수 있도록 한 세탁기의 헹굼수 순환장치에 관한 것이다.The present invention relates to a rinsing apparatus of a washing machine, and more particularly, to a rinsing water circulation system of a washing machine to reduce the consumption of the total washing water by pumping the rinsing water to purify it and then rewater it again.

도1은 종래 세탁기의 구조도로서, 이에 도시된 바와같이 세탁조(140)내에 물을 급수하기 위한 급수구(100)와; 세탁 및 헹굼을 수행하기 위한 펄세이타(120)와; 상기 펄세이타(120)를 회전시키기 위한 모터(130)로 구성된다.1 is a structural diagram of a conventional washing machine, and the water supply port 100 for supplying water in the washing tank 140 as shown therein; A pulsator 120 for performing washing and rinsing; It is composed of a motor 130 for rotating the pulsator 120.

미설명부호 110은 세제통이다Reference numeral 110 is a detergent container.

이와같이 구성된 종래 세탁기의 동작을 설명하면 다음과 같다.Referring to the operation of the conventional washing machine configured as described above is as follows.

먼저, 사용자가 세탁물을 세탁조(140)내에 넣고 임의의 코스를 선택하면, 마이크로컴퓨터(미도시)는 급수구(100)를 통해 일정수위까지 급수를 시작한다. 이때, 세제통(110)에 세제가 있으면 물과함께 혼합되어 투입된다.First, when a user puts laundry into the washing tank 140 and selects an arbitrary course, the microcomputer (not shown) starts water supply to a predetermined level through the water inlet 100. At this time, if there is a detergent in the detergent container 110 is mixed with water is added.

이후, 세탁코스에 따른 일정수위가 되면 본 세탁을 진행한다.After this, if a certain level according to the washing course proceeds to the main wash.

세탁동작이 끝나면 배수와 탈수를 행하고 다시 물을 급수하여 헹굼동작(표준 2회)을 진행한다음 세탁을 완료하게 된다.After the washing operation, drain and dewater, and then water again to proceed with the rinsing operation (standard twice) to complete the washing.

이를 순서적으로 타나내면 다음과 같다.If this appears in order, it is as follows.

세탁물투입-수위결정-세탁수급수-세탁-배수-탈수-헹굼수급수-헹굼-배수-탈수-완료Laundry input-Water level determination-Washing water supply-Washing-Drainage-Dewatering-Rinsing water supply-Rinsing-Drainage-Dewatering-Completion

이때, 일반적인 세탁기에 있어서, 디폴트(DEFOULT)된 세탁행정으로 세탁진행 시의 순서는 세탁 1회- 헹굼2회 정도이다.At this time, in the general washing machine, the order of the washing process by the default washing stroke (DEFOULT) is about once washing-twice rinsing.

따라서 이 때 사용한 물의 총 사용량은 중수위(약 70리터)를 예를들면 210리터이다.Therefore, the total amount of water used at this time is 210 liters, for example, the medium level (about 70 liters).

그러나 소비자들의 실제 세탁습관에 따른 헹굼횟수는 4회 정도 이므로 실제 소비량은 350리터 정도가 된다.However, since the number of rinses is about four times according to the actual washing habits of consumers, the actual consumption is about 350 liters.

이상에서 설명한 바와같이 종래의 세탁기는 헹굼횟수에 비례하여 물을 급수/배수하는 동작을 반복하기 때문에 물의 소비량이 많고, 상대적으로 세탁시간이 길어지는 문제점이 있었다.As described above, the conventional washing machine has a problem in that a large amount of water is consumed and the washing time is relatively long because the washing / receiving operation is repeated in proportion to the number of rinses.

본 발명의 목적은 이러한 종래의 문제점을 해결하기 위해 헹굼수의 세제농도가 타 용도로의 이용이 가능한 30ppm 이하인 것에 착안하여 헹굼시 헹굼수를 펌핑하여 정화시킨 후 다시 재 급수하도록 함으로써 물의 소비량 및 세탁시간을 줄일 수 있도록 한 세탁기의 헹굼수 순환장치를 제공하는데 있다.The purpose of the present invention is to solve the problems of the prior art by rinsing the detergent concentration of rinsing water is 30ppm or less that can be used for other purposes by pumping and purifying the rinsing water when rinsing and then re-water supply to consume water and washing It is to provide a rinsing water circulation system of a washing machine to reduce the time.

이하, 본 발명의 작용 및 효과에 관하여 일 실시예를 들어 설명한다.Hereinafter, the operation and effects of the present invention will be described with reference to one embodiment.

도2는 본 발명의 일 실시예시도로서, 이에 도시한 바와같이 세탁조(140)내에 물을 급수하기 위한 급수구(100)와; 세탁 및 헹굼동작을 수행하기 위한 펄세이타(120)와; 상기 펄세이타(120)를 회전시키기 위한 모터(130)와; 헹굼수를 펌핑하기 위한 펌프(210)와; 상기 펌핑된 헹굼수의 전도도를 측정하기 위한 전도도센서(220)와; 상기 전도도센서(220)의 측정값이 소정값이 될 때 까지 상기 펌핑된 헹굼수를 정화시켜 세탁조(140)내로 재 급수하는 필터부(230)로 구성한다.Figure 2 is an embodiment of the present invention, as shown in the water supply port 100 for supplying water in the washing tank 140; A pulsator 120 for performing washing and rinsing operations; A motor (130) for rotating the pulsator (120); A pump 210 for pumping rinsing water; A conductivity sensor 220 for measuring the conductivity of the pumped rinsing water; The filter unit 230 is configured to purify the pumped rinse water until the measured value of the conductivity sensor 220 reaches a predetermined value, and re-water the washing tank 140.

미설명부호 110은 세제통이다.Reference numeral 110 is a detergent container.

이와같이 구성한 본 발명의 일 실시예의 동작은 다음과 같다.Operation of one embodiment of the present invention configured as described above is as follows.

먼저, 세탁진행 과정은 종래와 동일하다. 즉, 사용자가 세탁물을 세탁조(140)내에 넣고 임의의 코스를 선택하면 마이크로컴퓨터(미도시)는 선택된 코스에 따른 수위만큼 급수구(100)를 통해 세탁수를 급수하도록 제어한다.First, the washing process is the same as before. That is, when the user puts the laundry into the washing tank 140 and selects an arbitrary course, the microcomputer (not shown) controls the water supply through the water supply port 100 by the water level according to the selected course.

이후, 소정수위까지 세탁수가 급수되면 모터(130)가 펄세이타(120)를 회전시켜 본 세탁을 진행한다.Then, when the wash water is supplied to a predetermined water level, the motor 130 rotates the pulsator 120 to perform the main washing.

상기에서 본 세탁이 끝나면 일단 배수를 하고, 헹굼수를 급수하여 헹굼동작을 진행한다.After the washing in the above, once the drainage, the rinsing water to proceed with the rinsing operation.

상기와 같이 헹굼동작을 하는 중에 펌프(210)는 헹굼수를 펌핑하고, 전도도센서(220)는 그 펌핑된 헹굼수의 전도도를 측정하며, 필터부(230)는 그 펌핑된 헹굼수를 정화시켜 세제통을 통해 세탁조내로 재 급수한다.During the rinsing operation as described above, the pump 210 pumps the rinsing water, the conductivity sensor 220 measures the conductivity of the pumped rinsing water, and the filter unit 230 purifies the pumped rinsing water. Refill the wash tub through the detergent container.

이때, 상기 필터부(230)는 활성탄 필터에 의한 흡착, 세라믹필터에 의한 제거, 중화제에 의한 중화 그리고 자외선 또는 초음파에 의한 분해 동작을 통해 급수된 헹굼수를 정화시킨다.At this time, the filter unit 230 purifies the rinsed water supplied through adsorption by activated charcoal filter, removal by ceramic filter, neutralization by neutralizing agent and decomposition by ultraviolet or ultrasonic wave.

이와같은 동작을 반복하면 헹굼수의 세제농도는 점점 줄어든다.Repeating this operation, the detergent concentration of the rinsing water is gradually reduced.

한편, 상기 전도도센서(220)에서 헹굼수의 전도도를 측정하면 이를 전도도와 세제농도 상관보정계수를 이용하여 환산함으로써 세제농도를 알 수 있다.Meanwhile, when the conductivity of the rinsing water is measured by the conductivity sensor 220, the detergent concentration may be determined by converting the conductivity using the conductivity and the detergent concentration correlation correction coefficient.

따라서 상기 전도도센서(220)의 측정값이 일반적으로 헹굼이 완전히 완료되었을 때의 세제농도인 3ppm이 되는 값이 되면 정화작용을 멈추고 탈수를 행한 다음 세탁을 종료한다.Therefore, when the measured value of the conductivity sensor 220 becomes a value of 3 ppm, which is generally a detergent concentration when rinsing is completely completed, the purification operation is stopped, dehydration is performed, and washing is terminated.

이와같이 하면 헹굼 4회 기준 그리고 고수위를 기준으로 했을 때 최대 270리터의 물을 절수할 수 있고, 세탁시간은 30분 정도를 줄일 수 있다.This saves up to 270 liters of water, based on four rinsing cycles and high water levels, and reduces washing time by 30 minutes.

이상에서 상세히 설명한 바와같이 본 발명은 헹굼수를 펌핑하여 정화시킨다음 재 급수하도록 함으로써 물의 사용량을 줄일 수 있고, 급수 및 배수시간을 줄임으로 인해 세탁시간을 줄일 수 있는 효과가 있다.As described in detail above, the present invention can reduce the amount of water used by pumping and purifying the rinsing water and then re-watering, thereby reducing the washing time by reducing the water supply and drainage time.
