Thereby, it can be set as a more intuitive and easy-to-understand information provision and operation means.

  As described above, with the washing machine having such a configuration, even if the user leaves the washing machine 1 while the reserved operation cannot be started due to forgetting to close the door 2, the washing machine No. 1 detects that the user is away from the place and notifies the abnormality so that the user can understand the situation and can take appropriate measures such as closing the door 2 so that the operation can be continued. Impossible state can be reduced / suppressed.

  In the present embodiment, the human body sensor 17 detects that the user leaves the washing machine 1 and notifies the abnormal state of the device again by the notification means 16. The approach may be detected, and the notification unit 16 may notify the abnormal state of the device again. According to the washing machine of this form, even when the operation cannot be continued due to forgetting to close the door 2, the washing machine 1 cannot continue the operation when a user or a person other than the user approaches the washing machine 1. It becomes possible to grasp that it is in a state.

(Embodiment 2)
In the present embodiment, the description of the same configuration and operation as in the first embodiment will be omitted.

  FIG. 6 is a system block diagram of the washing machine according to the second embodiment. In addition to the configuration of the first embodiment, the washing machine 1 shown in FIG. 6 is provided with a driving continuation determination unit 18 that determines whether driving operation can be continued.

  FIG. 7 is an operation flowchart of the washing machine according to the second embodiment. The human body sensor 17 operates in the same manner as in the first embodiment to detect the approach of a person (steps S101 to S105), and notifies the abnormal state of the device again by the notification means 16 (step S106). It is determined by means 18 whether the operation can be continued (step S107). If it is determined that the operation can be continued, the operation is resumed (step S109). If it is determined that the operation cannot be continued, the abnormality notification is continued (step S110).

  The abnormality notification in step S110 may be, for example, one that continues to notify the abnormality notification sound or one that notifies the abnormal sound every few minutes or several hours. When the abnormality notification is performed with the notification sound, the notification may be performed only for a certain period of time as a noise countermeasure by continuous notification. However, the configuration is such that the notification is performed only when the human body sensor 17 detects the approach of a person. It becomes possible to make the user recognize the continuation impossible state without making a noise for a long time.

For example, when the door 2 that has been opened receives an abnormality notification and determines whether or not it has been closed by the user, the operation continuity determination unit 18 can use a door open / close detection switch.

  In addition, although the washing machine of each said embodiment described what was called a washing dryer which has a drying function, it is clear that this invention is applicable also to the washing machine which does not have a drying function. Accordingly, the “laundry drying means for washing, rinsing, dehydrating, drying, etc. on the laundry” in each claim is replaced with the “laundry drying means” for “washing means for washing, rinsing, dehydration, etc. on the laundry”. Those replaced with “washing means” are also included in the present invention.

  As described above, even if the washing machine according to the present invention leaves the washing machine in a state in which the operation cannot be continued during the reserved operation, it detects that it has left or approached the place and reports an abnormality. Therefore, the user can recognize the state where driving cannot be continued and can reduce or suppress the state where driving cannot be continued, which is useful as a washing machine having a reserved driving function.
