The washing step of the washing machine 1 includes, for example, a washing step, a rinsing step, a dehydration step, and a drying step.

The charge control unit 132 controls the charge unit 70 to charge the ultrasonic cleaner 80. Specifically, the charge control unit 132 controls the charge unit 70 to start power supply from the power transmission coil 73 to the power receiving coil 83 when the limit switch of the accommodation detection unit 72 is turned from the off state to the on state. , Start charging the ultrasonic cleaner 80. Further, the charge control unit 132 detects when the limit switch of the accommodation detection unit 72 is changed from the on state to the off state, or the charge state detection unit 122 detects that the charge state of the ultrasonic cleaner 80 is not being charged. In that case (that is, when the infrared signal off is detected), the charging unit 70 is controlled to stop the power supply from the power transmitting coil 73 to the power receiving coil 83, and the charging of the ultrasonic cleaner 80 is completed.

Further, the charge control unit 132 is, for example, from the time when the limit switch of the accommodation detection unit 72 is turned on from the off state and the power supply from the power transmission coil 73 to the power receiving coil 83 of the ultrasonic cleaner 80 is started (at the start of charging). When the infrared sensor of the charging state detection unit 122 does not receive the infrared signal output from the ultrasonic cleaner 80 within 2 minutes (that is, the ultrasonic cleaner 80 is housed in the accommodating recess 71 of the charging unit 70. Then, charging of the ultrasonic cleaner 80 was started, but the state in which the charging state of the ultrasonic cleaner 80 was not detected as being charged by the charging state detecting unit 122 continued for 2 minutes), and the charging control unit 132 charged. The unit 70 is controlled to end the charging of the ultrasonic cleaner 80.

When the ultrasonic cleaner 80 is completely discharged, the infrared output unit 84 outputs an infrared signal during the time for determining whether or not to finish charging the ultrasonic cleaner 80 (2 minutes in this embodiment). This is the time required to output.

The accommodating state determination unit 133 includes a detection result by the accommodating detection unit 72 (that is, whether or not the ultrasonic cleaner 80 is accommodated in the accommodating recess 71) and a detection result by the charging state detecting unit 122 (that is, the ultrasonic cleaner 80). Based on whether the charged state is the charged state or the non-charged state), it is determined whether or not the ultrasonic cleaner 80 is accommodated in the accommodating recess 71 in a rechargeable state.

Specifically, when the accommodation detection unit 72 detects that the ultrasonic cleaner 80 is accommodated in the accommodation recess 71, and the charging state detecting unit 122 detects that the charging state of the ultrasonic cleaner 80 is in the charging state. The accommodating state determination unit 133 determines that the ultrasonic cleaner 80 is accommodating in the accommodating recess 71 in a rechargeable state. On the other hand, when the accommodation detection unit 72 detects that the ultrasonic cleaner 80 is accommodated in the accommodation recess 71, but the charge state detection unit 122 detects that the charge state of the ultrasonic cleaner 80 is a non-charged state. The accommodating state determination unit 133 determines that the ultrasonic cleaner 80 is not accommodating in the accommodating recess 71 in a rechargeable state.

The determination by the accommodation state determination unit 133 is performed from the time when the accommodation detection unit 72 detects that the ultrasonic cleaner 80 is accommodated in the accommodation recess 71 (that is, the limit switch of the accommodation detection unit 72 is on). Until it is detected by the unit 72 that the ultrasonic cleaner 80 is not accommodated in the accommodating recess 71 (that is, the limit switch of the accommodating detection unit 72 is in the off state), or until the power of the washing machine main body 2 is turned off. It is repeated at predetermined intervals.

When the ultrasonic cleaner 80 is not accommodated in the accommodating recess 71 in a rechargeable state, the end portion of the ultrasonic cleaner 80 provided with the infrared output portion 84 is located on the left side of FIG. When the infrared output unit 84 is accommodated in the accommodating recess 71 and does not face the charging state detecting unit 122, or the ultrasonic cleaner 80 is tilted toward the accommodating recess 71 so that the limit switch of the accommodating detection unit 72 is turned on. This includes the case where the infrared output unit 84 does not face the charge state detection unit 122 because the infrared output unit 84 is housed in the state of being in the state.

When the washing process is completed, the power supply control unit 134 switches the power supply of the washing machine main body 2 from on to off. Further, the power supply control unit 134 determines whether or not the charging state of the ultrasonic cleaner 80 is charging when the washing process is completed, based on the detection result by the charging state detecting unit 122. When it is determined that the charging state of the ultrasonic cleaner 80 is charging when the washing process is completed, the power supply control unit 134 determines that the charging state of the ultrasonic cleaner 80 is not charged by the charging state detecting unit 122. The switching of the power of the washing machine main body 2 from on to off is suspended until it is detected.

When the power control unit 134 suspends the switching of the washing machine main body 2 from on to off, the notification unit 135 holds the switching of the washing machine main body 2 from on to off. Is notified to the user via the display unit 112 of the operation panel 5.

Further, the notification unit 135 notifies the user of the detection result by the accommodation state determination unit 133 via the display unit 112 of the operation panel 5. For example, when the accommodation state determination unit 133 detects that the ultrasonic cleaner 80 is accommodated in the accommodation recess 71 in a rechargeable state, the notification unit 135 indicates that charging of the ultrasonic cleaner 80 has started. It is displayed on the display unit 112 of the operation panel 5 to notify the user. Further, for example, when the accommodation state determination unit 133 detects that the ultrasonic cleaner 80 is not accommodated in the accommodation recess 71 in a rechargeable state, the notification unit 135 "cannot charge the ultrasonic cleaner 80". Then, "I want you to confirm the accommodation direction of the ultrasonic cleaner 80 in the accommodation recess 71" is displayed on the display unit 112 of the operation panel 5 to notify the user. This notification is performed, for example, when the infrared sensor of the charging state detection unit 122 does not receive the infrared signal output from the ultrasonic cleaner 80 even after 1 second has passed from the start of charging the ultrasonic cleaner 80.

Further, the notification unit 135 detects, for example, a high level pulse continuously for 1 second or longer before the limit switch of the accommodation detection unit 72 is turned on from the off state and charging of the ultrasonic cleaner 80 is started. In this case, the display unit 112 of the operation panel 5 is displayed to notify the user that "a circuit error has occurred". Further, when a low level pulse is continuously detected for, for example, 5 seconds or more during charging, the notification unit 135 displays "charging is completed" on the display unit 112 of the operation panel 5 to notify the user. do.

The measuring unit 136 measures, for example, the time elapsed from the start of charging of the ultrasonic cleaner 80 and the time when the high level pulse or the low level pulse is continuously detected by the infrared sensor of the charging state detecting unit 122.

Next, with reference to FIG. 5, the power on / off process of the washing machine main body 2 at the end of the washing process will be described. The process described below is performed by the control device 100 executing a predetermined program.

When the washing process is completed (step S1), the power supply control unit 134 determines whether or not the charging state of the ultrasonic cleaner 80 is being charged at the end of the washing process based on the detection result by the charging state detecting unit 122. Determine (step S2).

When it is determined that the charging state of the ultrasonic cleaner 80 is being charged at the end of the washing process, the power supply control unit 134 suspends switching from the power on to the power of the washing machine main body 2 (step S3). Further, the notification unit 135 notifies the user by displaying on the display unit 112 of the operation panel 5 that the switching of the power supply of the washing machine main body 2 from on to off is suspended (step S4). Then, steps S2 to S4 are repeated until the charging state detecting unit 122 detects that the charging state of the ultrasonic cleaner 80 is not being charged and it is determined that the charging state of the ultrasonic cleaner 80 is not being charged. Is done.

On the other hand, when it is determined that the charging state of the ultrasonic cleaner 80 is not charging, the power supply control unit 134 switches the power supply of the washing machine main body 2 from on to off (step S5), and at the end of the washing process. The power processing of the washing machine main body 2 is completed.

Subsequently, with reference to FIG. 6, the timer interrupt process after the charging of the ultrasonic cleaner 80 is started will be described. This timer interrupt process is set to be performed at regular intervals after the charging of the ultrasonic cleaner 80 is started until the charging of the ultrasonic cleaner 80 is completed. The process described below is performed by the control device 100 executing a predetermined program.

When charging of the ultrasonic cleaner 80 is started and a timer interrupt process is generated, the charge control unit 132 determines whether or not the limit switch of the accommodation detection unit 72 is in the ON state (that is, the ultrasonic cleaner 80 has the accommodation recess 71). (Whether or not it is housed in) is determined (step S11).

When it is determined that the limit switch of the accommodation detection unit 72 is in the ON state, the charge control unit 132 determines that the infrared sensor of the charge state detection unit 122 outputs the first infrared ray from the infrared output unit 84 of the ultrasonic cleaner 80. It is determined whether or not the signal has been received (step S12).

On the other hand, when it is determined that the limit switch of the accommodation detection unit 72 is in the off state, the charge control unit 132 ends the charging of the ultrasonic cleaner 80 (step S19), and the timer interrupt process ends.

When it is determined that the infrared sensor of the charge state detection unit 122 has not received the first infrared signal output from the infrared output unit 84 of the ultrasonic cleaner 80, the charge control unit 132 is measured by the measurement unit 136. Based on the time, it is determined whether or not the first time (for example, 1 second) has elapsed from the time when the charging of the ultrasonic cleaner 80 is started (step S13).

If it is determined that the first time has not elapsed, the charge control unit 132 continues charging the ultrasonic cleaner 80 (step S17), and the timer interrupt process ends.

On the other hand, when it is determined that the first time has elapsed, the notification unit 135 starts charging the ultrasonic cleaner 80, and then the infrared output unit of the ultrasonic cleaner 80 even if the first time elapses. It is determined whether or not the error notification (charging error notification) indicating that the first infrared signal output from 84 has not been received has already been performed by the timer interrupt processing prior to the timer interrupt processing currently being performed. (Step S14). When it is determined that the charging error notification has not yet been performed, the notification unit 135 notifies the user of the charging error notification via the display unit 112 of the operation panel 5 (step S15).

When it is determined that the first time has passed and the charging error notification is performed, the charging control unit 132 starts charging the ultrasonic cleaner 80 based on the time measured by the measuring unit 136. It is determined whether or not the second time (for example, 2 minutes) has elapsed from (step S16).

If it is determined that the second time has not elapsed, the charge control unit 132 continues charging the ultrasonic cleaner 80 (step S17), and the timer interrupt process ends.

On the other hand, when it is determined that the second time has elapsed, the charge control unit 132 ends the charging of the ultrasonic cleaner 80 (step S19), and the timer interrupt process ends.

Further, in step S12, when it is determined that the infrared sensor of the charge state detection unit 122 has received the first infrared signal output from the infrared output unit 84 of the ultrasonic cleaner 80, the charge control unit 132 is in the charge state. It is determined whether or not the infrared signal off is detected by the detection unit 122 (that is, whether or not it is detected that the charged state of the ultrasonic cleaner 80 is not being charged) (step S18).

If the infrared signal off is not detected, the charge control unit 132 continues charging the ultrasonic cleaner 80 (step S17), and the timer interrupt process ends. On the other hand, when the infrared signal off is detected, the charge control unit 132 ends the charging of the ultrasonic cleaner 80 (step S19), and the timer interrupt process ends.

According to the washing machine 1 of the first embodiment, when it is determined that the ultrasonic cleaner 80 is being charged when the washing process is completed, it is determined that the ultrasonic cleaner 80 is not being charged. The switching of the power of the washing machine main body 2 from on to off is suspended until the power is turned on. As a result, the ultrasonic cleaner 80 can be reliably charged, and it is possible to avoid the occurrence of a situation in which the ultrasonic cleaner 80 is intended to be charged but cannot be charged.

Further, when the switching of the power supply of the washing machine main body 2 from on to off is suspended, the display unit of the operation panel 5 indicates that the switching of the power supply of the washing machine main body 2 from on to off is suspended. The user is notified via 112. As a result, when the ultrasonic cleaner 80 is being charged after the washing process is completed, the user accidentally turns off the power of the washing machine main body 2 and intends to charge the ultrasonic cleaner 80, but the charging is not possible. You can avoid the situation.

Further, it is determined whether or not the ultrasonic cleaner 80 is accommodated in the accommodating recess 71 in a rechargeable state, and the determination result is notified to the user via the display unit 112 of the operation panel 5. As a result, for example, when the ultrasonic cleaner 80 is housed in the accommodating recess 71 in a non-chargeable state, the ultrasonic cleaner 80 remains housed in the accommodating recess 71 in a non-chargeable state and the ultrasonic cleaner It is possible to avoid the occurrence of a situation in which the 80 is intended to be charged but cannot be charged. Further, for example, when the ultrasonic cleaner 80 is housed in the storage recess 71 in a rechargeable state, it can be confirmed that the charging of the ultrasonic cleaner 80 has started, and the convenience can be improved.

Regarding the accommodation state determination unit 133 and the notification unit 135, either one or both of them may be omitted. Further, the blower fan 101 and the heater 103 can also be omitted.

The accommodation detection unit 72 is not limited to the case where it is configured by a limit switch, and any configuration that can detect whether or not the ultrasonic cleaner 80 is accommodated in the accommodation recess 71 can be adopted.

The charge state detection unit 122 is not limited to the case where it is composed of an infrared sensor, and can adopt any configuration that can detect whether the charge state of the ultrasonic cleaner 80 is charging or not charging.
