Description

The present invention relates to a drum-type washing machine having a reserved operation function.

Conventionally, in the reserved operation standby state, the lid is not locked, so the lid can be freely opened and closed, and after the lid is closed, the lid is automatically locked and the operation operation is started at the reserved time. However, in recent years, in order to meet the safety requirement that "after closing the lid, the operation must not be started without any operation", it has become necessary to always operate the start button or the like after closing the lid. For this reason, some washing machines are configured so that the lid cannot be opened and closed by locking the lid in the reservation standby state (see, for example, Patent Document 1).

However, in the conventional washing machine configured to lock the lid so that the lid cannot be opened and closed when the reserved operation is set, the lid can be opened when the user wants to add laundry in the reserved standby state. Since it cannot be done, it takes time to turn off the power and set the reservation again. Further, even if the lid can be opened, there is a problem that the reserved operation is not executed if the "start" button is forgotten to be operated again after the lid is closed.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a washing machine capable of suppressing forgetting to execute a reservation while the reservation operation is temporarily stopped.

In order to solve the above-mentioned conventional problems, the washing machine of the present invention provides a display or a notification prompting the user to restart the reserved operation during the reserved operation suspension and until the reserved operation is reset.

In addition, if the reserved operation is not restarted even after a predetermined time has passed after opening and closing the lid, a display or notification indicating that the reserved operation is still suspended is displayed or notified.

According to the present invention, the setting is made because the user forgets to operate the "start" button or the like again after opening and closing the lid for the purpose of adding laundry while waiting for the reserved operation. It is possible to prevent the reserved operation from being executed.
