  • a washing machine capable of performing the reservation operation is disclosed. The washing machine disclosed in the patent literature 1 does not start a washing operation immediately even if a reservation operation start key is operated, but actually starts the washing operation after a reservation waiting time since the reservation operation start key is operated.
  • Patent Literature 1 Japanese Laid-Open Patent Publication No. 2004-65408
  • a conventional washing machine tends to focus on shortening an operation time, such as increasing a rotation speed of the motor, increasing the rotation speed of the washings in the washing drum and improving cleaning power per unit time, in ordinary washing operation rather than the reservation operation.
  • the washings are easy to be damaged and wrinkled in the case of increasing the rotation speed in this way, and intact conditions of the washings may be sacrificed to some extent to ensure the shortening of the operation time and the cleaning power.
  • the washing machine having a reservation operation function described above usually performs the ordinary washing operation and the reservation operation in substantially same conditions, besides starting the washing operation after the reservation waiting time. Therefore, the washing machine disclosed in the patent literature 1 has a space for improvement in an aspect of considering that the operation times (execution times) of various processes and the rotation speeds of the motor in various processes during the ordinary washing operation and the reservation operation are substantially the same and in an aspect of considering that the intact conditions of the washings also are sacrificed in the case of the reservation operation regardless of the shortening of the operation time.
