Problems solved by technology

As such, if the door is designed to open during or after the wash cycle, the user can get burned due to contact with the rotating drum
Meanwhile, in order to prevent the user from being burned, if the door is controlled to be closed until the washing, rinsing, and spinning cycles are completed, the user may complain that the door cannot be opened at the beginning of the operation.

Abstract

Provided is a drum type washing machine including a heating unit (41) for heating the washing water in the heating water tunnel (26), a water feeding unit (37 or 38b) for controlling the washing water feeding to the water tunnel (26), a water draining unit (36) for controlling the washing water draining from the water tunnel (26), and a control unit (44) for controlling a series of circulation including washing, rinsing, and spin-drying. The control unit (44) executes a cooling circulation of repeat water feeding and draining by controlling the feeding unit (37 or 38b) and draining unit, the heated washing water is cooled to a predetermined temperature till the draining operation stage after the high-temperature washing circulation, wherein the high-temperature washing circulation is for a washing operation with washing water heated by the heating unit (41) to a higher temperature than the predetermined temperature.

Description

technical field [0001] The present invention relates to a drum type washing machine for performing washing, rinsing, dehydration cycles, etc. in a rotary drum having a horizontal or inclined rotation axis. Background technique [0002] FIG. 6 shows a conventional drum type washing machine. Next, its configuration will be described. [0003] As shown in FIG. 6 , a rotary drum 1 provided with a plurality of drum holes 2 throughout its cylindrical wall is housed in a water tub 3 in such a manner that the rotary drum 1 is allowed to rotate in the water tub 3 . One end of the rotary shaft 4 is fixed to the central axis of rotation of the rotary drum 1 in an approximately horizontal direction. And, the other end of the rotary shaft 4 is fixed to an idler pulley (idling pulley) 5 . The rotary drum 1 is rotated by the first motor 6 at a first rotation speed N1 (for example, 53 rpm) during a washing or rinsing cycle. And, the rotary drum 1 is driven to rotate by the second motor ...
