Description

식기세척기의 배수방법Drainage of the dishwasher

본 발명은 식기세척기의 배수방법에 관한 것으로, 특히 세척초기에 세척실내에 잔수를 배수할 때 세척실내에 잔수를 감지하고 이 감지된 잔수에 따라 배수시간을 재설정하여 배수하도록 함으로써, 상기 세척실내에 잔수가 존재하지 않도록 한 식기세척기의 배수방법에 관한 것이다.The present invention relates to a method for draining a dishwasher, and in particular, when the remaining water is drained into the washing chamber in the initial stage of washing, the remaining water is sensed in the washing chamber and the drainage time is reset according to the detected residual water to drain the water. The present invention relates to a drainage method of a dishwasher in which residual water does not exist.

일반적으로 우리의 가정에서 사용되는 식기세척기의 경우 일련의 세척,헹굼,건조행정완료후에는 배수가 완전히 이루어지지 않고 세척실내에 세척수가 남아 있게 된다.In general, the dishwasher used in our homes, after a series of washing, rinsing, and drying administration, drainage is not completely done and the washing water remains in the washing chamber.

그러므로 식기세척시 초기에는 바로 급수를 하지 않고, 상기 세척실에 남아 있는 세척수를 배수시키기 위하여 초기배수시간(7초)동안 배수를 실시한후, 이어서 세척실에 소정의 수위로 급수를 하면서 세척행정을 진행하고, 상기 세척행정완료후에는 매행정마다 발생되는 오염된 세척수를 중간배수시간(20초 배수, 3 초 휴지, 5초 배수)동안 배수한후 다시 소정의 수위로 급수하고 일련의 세척행정을 진행하도록 되어 있다.Therefore, do not immediately supply water at the time of dish washing, drain water for the initial draining time (7 seconds) in order to drain the remaining washing water in the washing chamber, and then wash water while supplying water to the washing chamber at a predetermined level. After the completion of the washing stroke, the contaminated washing water generated every stroke is drained for an intermediate drainage time (20 seconds drain, 3 seconds pause, 5 seconds drain), and then water is supplied again to a predetermined level and a series of washing strokes are performed. It is supposed to be.

그러므로 종래의 식기세척기에서는 세척초기 급수전에 세척실내에 잔수량에 관계없이 무조건 기설정된 초기배수시간(7초)동안 배수를 실시한후 이어서 급수하면서 세척을 하도록 되어 있어, 가령 사용중에 세척행정을 재설정하거나 혹은 마이콤이 운전신호를 인식하지 못하여 정상적인 배수가 이루어지지 않아 세척실에 잔수가 많이 남아 있는 상태에서 식기세척 초기에 상기 기설정된 초기배수시간(7초)동안에는 상기 많이 남아 있는 세척수를 배수시키지 못한 상태에서 새로운 세척수를 급수하면서 세척을 하게 되므로 상기 새로이 급수되는 세척수는 상기 남아있는 세척수에 의하여 오염되거나 혹은 원하는 정도의 깨끗한 세척수로 세척을 하지 못하게 되는 문제점을 가지게 되었다.Therefore, in the conventional dishwasher, irrespective of the amount of water remaining in the washing room before the initial water supply, the water is unconditionally drained for a predetermined initial drainage time (7 seconds) and then washed with water. Alternatively, when the microcomputer does not recognize the operation signal and normal drainage is not performed, a large amount of water remains in the washing room, and thus the remaining washing water cannot be drained during the preset initial drainage time (7 seconds) in the initial stage of dish washing. Since the new washing water is washed at the water supply, the newly watered washing water is contaminated by the remaining washing water or has a problem that it cannot be washed with the desired amount of clean water.

본 발명의 목적은 초기 식기세척시 급수전에 세척실의 잔수를 배수함에 있어서, 상기 세척실에 남아있는 잔수를 감지하여 이 감지된 잔수가 기설정된 소정의 수위이상이면, 기설정된 초기배수시간보다 긴 중간배수시간으로 배수하여 세척실내에 잔수가 존재하지 않도록 함으로써, 초기 세척시 보다 깨끗한 세척수로 세척을 할수 있도록 하고자 하는데 있다.An object of the present invention is to detect the residual water remaining in the washing chamber in draining the residual water of the washing chamber before the water supply during the initial dish washing, if the detected residual water is more than the predetermined predetermined level, longer than the predetermined initial draining time By draining to the middle drainage time so that no residual water is present in the washing room, it is intended to be able to wash with cleaner water at the time of initial washing.

상기의 목적을 실현하기 위하여 본 발명은 초기화상태에서 급수전에 세척실에 남아 있는 잔수를 감지하고, 이 감지된 잔수가 기설정된 소정의 잔수 이상인가를 판단하여, 상기 잔수가 기설정된 소정의 잔수 이상이 아니면, 기설정된 초기배수시간으로 배수하고, 급수하면서 세척하고, 상기 감지된 잔수가 기설정된 소정의 잔수 이상이면, 중간배수시간으로 배수한후 급수하고 세척을 하도록 한 것을 특징으로 한다.In order to realize the above object, the present invention detects the residual water remaining in the washing chamber before the water supply in the initialization state, and determines whether the detected residual water is equal to or greater than the predetermined residual water, and the residual water is equal to or greater than the predetermined residual water. Otherwise, it is drained by a predetermined initial drainage time, and washed while supplying water, and if the detected residual water is more than a predetermined predetermined residual water, it is characterized in that it is drained to an intermediate drainage time and then watered and washed.
