Abstract

A washing machine capable of performing a scheduled operation in which washing is completed until a scheduled end time, and the condition and cleaning power of laundry such as laundry are emphasized. The washing machine (1) is provided with a washing machine main body (2), a washing tub (4) and a motor (61), and can perform a scheduled operation to end a plurality of processes of washing clothes until the scheduled end time, and the washing machine (1) has a time The acquisition unit (27) and the control unit (7), wherein the time acquisition unit (27) acquires the remaining time until the end target time set based on the end scheduled time before the start of the washing process (SP2), and the control unit ( 7) According to the remaining time obtained by the time acquisition part (27), it is decided whether to execute each process in a normal reservation mode or a special reservation mode, wherein in the normal reservation mode, the average rotational speed of the motor (61) is adjusted to a specified value and A mode in which each process is executed with a predetermined execution time, and the special reservation mode is a mode in which the average rotation speed of the motor (61) is set smaller and the execution time is set longer than the normal reservation mode. This washing machine realizes the scheduled operation which reduces the damage and wrinkles of the laundry by simple control.

Description

technical field [0001] The present invention relates to a washing machine capable of executing a scheduled operation in which washing is completed and the condition and cleaning power of laundry such as laundry are emphasized until a scheduled end time. Background technique [0002] Conventionally, there is known a washing machine comprising: a main body of the washing machine; a washing tub disposed inside the main body of the washing machine; The scheduled operation of a plurality of courses (for example, a washing course, a rinsing course, and a spin-drying course) for washing the laundry can be automatically ended by the scheduled end time. Patent Document 1 discloses such a washing machine capable of scheduled operation. The washing machine disclosed in Patent Document 1 does not start the washing operation immediately even if the scheduled operation start key is operated, but actually starts the washing operation after the scheduled waiting time has elapsed since the ...
