Abstract

본 발명은 세탁기의 세제 투입량 제어장치 및 방법에 관한 것으로서, 특히 세탁시 세탁수의 성분에 따라 세제 투입량을 결정하여 세탁성능을ㄹ 향상시키고 세제 과다투입에 따른 경제적손실 및 환경오염을 방지하도록 한 세탁기의 세제 투입량 제어장치 및 제어장치 및 방법에 관한 것이다. 상기와 같은 목적을 달성하기 위해서 본 발명에 따른 세제 투입량 제어장치 및 방법은 제어신호에 따라 세탁수를 공급하는 급수 밸브와, 상기 세탁수의 TDS농도와 온도를 센싱하여 출력하는 감지 수단과, 상기 감지 수단을 거친 세탁수와 세탁물과 세제가 혼합되어 세탁행정이 수행되는 세탁조와, 상기 세탁조에 담긴 세탁수의 수위를 감지하여 출력하는 수위감지부와, 제어신호에 따라 상기 세탁조의 세탁수를 배출하는 배수 밸브와, 상기 감지 수단의 출력신호를 받아 세제 투입량을 산출하는 제어 수단과, 상기 제어 수단에서 산출된 세제 투입량을 표시하는 표시부로 이루어지며, 세탁행정을 위해 세탁물(物), 세탁수와, 수위의 조건을 설정하는 제1단계와, 현수위가 상기 설정수위와 같을 때까지 급수하여 TDS농도 및 온도를 센싱하는 제2단계와, 현시간이 보상시간으로 될때까지 경도농도을 연산하고 세제 투입량을 산출하는 제3단계와, 상기 보상시간이후 사용자에게 세제 투입량을 알려주는 제4단계와, 상기 설정수위에서 상기 세제량을 투입하여 세탁행정을 수행하는 제5단계로 이루어짐을 특징으로 한다. 따라서, 본 발명에 따른 세탁기의 세제 투입량 제어장치 및 방법은 세탁수의 환경에 적극적으로 대응하여 과다투입 되는 세제량을 방지하므로 사용자들의 세제사용을 절감하고 동시에 환경보호 효과도 있으며, 최적의 세제량으로 항상 일정한 세탁 성능을 나타내는 효과가 있다.The present invention relates to a detergent input control device and method of the washing machine, in particular, to determine the detergent input amount according to the components of the washing water during washing to improve the washing performance and to prevent the economic loss and environmental pollution due to excessive detergent input It relates to a detergent dosage control device and a control device and a method of the. In order to achieve the above object, the detergent input amount control apparatus and method according to the present invention includes a water supply valve for supplying wash water according to a control signal, sensing means for sensing and outputting the TDS concentration and temperature of the wash water, Washing tank through the washing means and the laundry and the detergent is mixed with the washing means and the washing tank is performed, the water level sensing unit for detecting and outputting the water level of the washing water contained in the washing tank, and discharges the washing water of the washing tank in accordance with a control signal It consists of a drain valve, a control means for calculating the detergent input amount in response to the output signal of the sensing means, and a display unit for displaying the detergent input amount calculated by the control means, and the laundry (thing), washing water and A first step of setting the condition of the water level, a second step of sensing the TDS concentration and temperature by supplying water until the suspension level is equal to the set water level; A third step of calculating the hardness concentration and calculating the detergent input amount until the compensation time is reached; a fourth step of informing the user of the detergent input amount after the compensation time; and performing the laundry administration by inputting the detergent amount at the set water level. Characterized in that the fifth step. Therefore, the detergent input amount control apparatus and method of the washing machine according to the present invention actively prevents the detergent amount to be over-injected in response to the environment of the wash water, thereby reducing the use of detergent of the user and at the same time protect the environment, and always with the optimal amount of detergent It has the effect of showing a constant washing performance.
