Abstract: A motor for a drum type washing machine is disclosed, wherein noise is reduced. To this end, the drum type washing machine is provided with a washing motor (20) comprising a stator (30) fitted at a rear surface of a tub (3) and having a plurality of slots (33) on which a coil (33a) is wound; a rotor (40) provided at an outer side of the stator (30) with a permanent magnet (41) and connected to a washing drum (9) inside the tub (3) by a driving shaft (17); and isolating means (50, 60, 70, 80) for isolating a gap (21) between the stator (30) and the rotor (40) not to be communicated with the stator (30) and the rotor (40).

Abstract: The present invention discloses a method for washing in a washing machine, which can measure an accurate washing load before actual washing is carried out. To do this, the present invention provides a method for controlling washing in a washing machine, including (a) introducing laundry into a drum of the washing machine, (b) measuring an initial washing load caused by the introduced laundry, (c) repeating water supply to the drum for a fixed time period for maintaining a minimum water level determined by the initial washing load, taking water absorbed to the laundry into account, (d) after the preset water supply time period, determining a final washing load in the drum based on a number of water resupply times for an elapsed time from the initial water supply, and (e) washing the laundry by a washing method preset according to the determined final washing load.

Abstract: Structure of driving unit in a drum type washing machine including a tub mounted inside of a cabinet, a drum mounted inside of the tub, a shaft connected to the drum mounted inside of the tub for transmission of a driving force from a motor to the drum, a front bearing and a rear bearing mounted on an outer circumference of the shaft at opposite end portions thereof respectively, a bearing housing built in a central portion of a rear wall of the tub for supporting the front bearing, a rotor composing the motor together with the rotor, and coupled to the rear end portion of the shaft, a stator fixed to the tub rear wall inward of the rotor to compose the motor together with the rotor, a connector serration coupled to the outer circumference of the shaft in front of the rear bearing and fixed to the rotor, for transmission of a rotating power from the rotor to the shaft, and a bearing bracket fixed to the rear wall of the tub to cover an outside of the rotor and support the rear bearing, thereby reducing noise,
