Abstract

본 발명은 탈수동작시 탈수조를 회전운동시키는 전동모터의 회전수를 근거로 세탁물의 탈수정도를 검출하여 탈수상태를 제어하는 것을 목적으로 하는 세탁기의 탈수제어장치에 관한 것으로, 탈수조(20)와 간섭을 일으키지 않은 펄세이터(21)와 연결되어 있는 펄세이터 구동축(22)의 하단에 전동모터(23)가 지지체(24)에 설치되어 있는 세탁기에 있어서, 상기 전동모터(23)의 회전수를 검출하기 위한 회전수검출사단과, 탈수모드설정시 검출된 회전수가 기설정치 이상인 상태로 소정시간이 경과되면 상기 전동모터(23)의 구동이 정지되도록 제어하는 제어부(102)를 포함하여 구성되고, 상기 회전수검출수단은 상기 펄세이터 구동축(22)과 전동모터(23)의 사이에 등간격으로 홀이 형성된 홀원판(70)을 상기 펄세이터 구동축(22)과 일체형으로 구성하고, 상기 홀과 대응적인 위치에 발광소자(72)와 수광소자(73)가 형성된 브라켓트(71)를 상기 전동모터(23)에 고정설치하여 사용자가 별도로 탈수시간을 설정하지 않아도 최적의 상태로 탈수동작을 수행되어진다.The present invention relates to a dehydration control device for a washing machine for controlling the dehydration state by detecting the degree of dehydration of laundry based on the rotational speed of the electric motor for rotating the dehydration tank during the dehydration operation, the dehydration tank (20) In a washing machine in which an electric motor 23 is installed on a support 24 at a lower end of a pulsator drive shaft 22 connected to a pulsator 21 that does not cause interference with the pulsator 21, the rotation speed of the electric motor 23 is reduced. And a controller 102 for controlling the driving of the electric motor 23 to be stopped when a predetermined time has elapsed in a state in which the number of revolutions detected when the dehydration mode is set is equal to or greater than a preset value. The rotation speed detecting means may be configured such that the hole disc 70 having holes formed at regular intervals between the pulsator drive shaft 22 and the electric motor 23 is integrally formed with the pulsator drive shaft 22, and the holes Exaggerated The bracket 71 formed with the light emitting element 72 and the light receiving element 73 at a corresponding position is fixedly installed on the electric motor 23 to perform the dehydration operation in an optimal state even if the user does not separately set the dehydration time. Lose.
