Description

Water supply method of washing tank washing course {WASHING MACHINE}

본 발명은 세탁조 세정코스의 급수방법(이하, 급수방법이라 칭함)에 관한 것으로써, 상세하게는 온수와 냉수를 동시에 급수하는 상태에서 세탁조 내의 온도를 설정된 온도와 비교판단하고, 그 결과에 따라 계속 급수를 진행하거나 냉수의 급수를 중지시켜 세탁조 세정에 가장 적합한 설정온도로 급수하는 과정이 빠르게 수행되도록 한 것이다.The present invention relates to a water supply method (hereinafter, referred to as a water supply method) of a washing tank cleaning course. Specifically, the temperature in the washing tank is compared with the set temperature in the state of simultaneously supplying hot water and cold water, and the result is continued according to the result. By supplying water or stopping the supply of cold water, the process of supplying water to the set temperature most suitable for washing the washing tank is performed quickly.

일반적으로 세탁기는 케이스의 내부에 세탁외조와 세탁내조가 구비되고, 세탁내조를 회전시키기 위해 세탁외조에 모터가 설치되어 구성된다.In general, the washing machine is provided with a washing tub and a washing tub inside the case, and a motor is installed in the washing tub to rotate the washing tub.

상기와 같은 세탁기는 여러횟수의 세탁을 수행한 후, 세탁물의 오염된 찌꺼기나 세탁세제의 잔여물이 세탁내조나 세탁외조에 침적되어 침적된 오염물질에 의한 악취나 다음번 세탁에서 세탁물이 재오염되는 등의 문제점이 발생된다.The washing machine may be washed several times, and contaminated garbage or residues of the laundry detergent may be deposited in the washing tank or the washing tank, and the smell may be recontaminated in the next laundry. Problems such as this occur.

따라서, 상기 세탁조 내의 오염된 침적물을 세정하기 위해 세탁조내에 물을 급수하고 세정세제를 투입한 상태에서 일정수류를 발생시켜 상기 침적물을 씻어내는 세정코스를 수행한다.Therefore, to clean the contaminated deposits in the washing tank, water is supplied to the washing tank and a washing course is generated to generate a certain water flow while the washing detergent is put therein to wash the deposits.

상기 세정코스에서 물은 세정세제의 희석 및 세정효율을 높이기 위해 가급적 설정된 온도의 온수가 급수되는데, 종래에는 상기 급수되는 물이 설정온도의 세정수가 되도록 하기 위해서는 우선 온수만을 급수한 상태에서 냉수를 급수하며 설정온도를 맞추게 된다.In the cleaning course, water is supplied with hot water at a predetermined temperature to increase the dilution and cleaning efficiency of the cleaning detergent. In the related art, in order to ensure that the water to be supplied is washing water at a predetermined temperature, cold water is first supplied with only hot water. And the set temperature is adjusted.

상기와 같은 급수과정은 일정량의 온수를 급수한 후, 냉수를 급수해야 하기때문에 설정수위까지 물이 도달되는 시간이 지연된다.In the water supply process as described above, since water must be supplied after supplying a certain amount of hot water, the time for reaching the water level is delayed.

또한, 상기와 같이 냉수와 온수가 초기부터 구분되어 급수되는 상태는 이들이 효율적으로 혼합되지 못하는 상태이기 때문에 급수된 세정수의 여러구간에서 온도의 변화가 심해, 세탁외조의 일측에 설치된 온도감지센서에서 정확한 온도를 감지하기 어려운 문제점이 발생된다.In addition, since the cold water and hot water are separated from the initial water supply as described above, since they are not mixed efficiently, the temperature change is severe in various sections of the supplied water, so that the temperature sensor installed at one side of the washing tank The problem is that it is difficult to detect the correct temperature.

본 발명은 상기와 같은 문제점을 해소시키기 위해 창안된 것으로써, 설정수위까지 물을 급수하는 시간을 단축시키고, 물이 급수될 때의 온도감지가 보다 정확하도록 하는 급수방법을 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, the object of the present invention is to provide a water supply method to shorten the time for watering water up to the set water level, and to more accurately sense the temperature when water is supplied. .
