Japanese Patent Laid-Open No. 3-184597 Japanese Patent No. 3067923

By the way, recently, it has been demanded to refrain from power consumption by electric devices in a power consumption peak time zone in one day. As one of the methods for suppressing the power consumption in the power consumption peak time zone, the following method can be considered in order to avoid the operation in the time zone. In the washing machine, when the power consumption peak time zone is reached during the washing operation, if the washing operation is temporarily suspended and the operation is resumed after the peak time zone has passed, there is no problem in terms of power. However, in this case, since the washing operation is temporarily interrupted, when the operation is resumed from the state of the interruption after the interruption and the operation is ended as it is, the finish of the washing may be deteriorated.
Note that the reservation function sets the driving start time earlier than the current time, and does not temporarily stop driving and resume driving after a predetermined time.

  Therefore, an object of the present invention is to provide a washing machine capable of preventing the finish of the laundry from being deteriorated even if the operation is resumed after the operation is temporarily suspended.

A washing machine according to an embodiment includes a pause switch, a display unit, and a control device, and the control device is operated by the user during a washing operation or a washing / drying operation. Based on the above, the currently running operation is paused, the point at which the process was stopped is memorized, the interruption time is displayed on the display unit, and the operation is automatically resumed after the displayed time has elapsed. The washing process of the washing operation includes a water supply operation and a washing operation, and the control device resumes the operation regardless of the stage when the control device is temporarily interrupted during the washing process. After that, start the washing operation from the beginning.

Is provided. The operation dial 55 outputs a signal corresponding to the rotation angle and gives it to the control device 39. The display unit 56 includes a time display unit 56a.

  The control device 39 is composed mainly of a microcomputer and functions as a control means for controlling the overall operation of the washing machine. As shown in FIG. 3, the control device 39 receives various signals from the switches 41 to 54 provided on the operation panel 40, signals according to the rotation angle from the operation dial 55, and a signal in the water tank 5. A water level detection signal from the water level sensor 57 that detects the water level, an exhaust temperature sensor 58 that detects the exhaust temperature, and a temperature detection signal from the water tank temperature sensor 59 that detects the temperature in the water tank 5 indicate the rotational speed of the motor 12. A rotation speed detection signal is input from the rotation sensor 60 to be detected. A non-volatile memory 61 is connected to the control device 39.

  Based on these input signals and a pre-stored control program, the control device 39 supplies the display unit 56 of the operation panel 40, the motor 12, the water supply valve 62 for supplying water into the tank 4, the drain valve 34, and the finishing.

Control.

  Further, the control device 39 has a built-in clock means and can recognize the current time. The time information in the clock means may be obtained from an external network such as the Internet, or may be set by the user.

  FIG. 4 shows an example of a standard course of a washing course (washing operation) and a drying course (drying operation). The washing course is a course in which after the weight is detected, a washing process (water supply, washing), a rinsing process (drainage, dehydration, shower rinsing, dehydration, water supply, rinsing), and a dehydration process (drainage, dehydration (final dehydration)) are performed in this order. It is. The weight detection operation before the washing process is performed by turning the pulsator 10 while the laundry is stored in the rotating tub 6 (without water) and detecting the electrical load (current, etc.) applied to the motor 12. Is detected. Based on this result, the water level, required time, etc. are determined.

  In the washing course, the water supply operation is performed by opening the water supply valve 62 and supplying water into the tank 4. The water level at this time is detected by the water level sensor 57. The washing operation is performed by rotating the pulsator 10 forward and backward at a predetermined rotational speed in a state where water is stored in the tank 4 and a detergent is added. The draining operation is performed by opening the drain valve 34 and discharging the water in the tank 4 to the outside of the machine. The dehydrating operation is performed by rotating the rotating tub 6 at a high speed in one direction. The shower rinsing operation is performed while supplying water into the rotary tank 6 and rotating the rotary tank 6 while dehydrating, and is performed with the drain valve 34 opened. Therefore, the rinsing operation is performed by rotating the pulsator 10 forward and backward at a predetermined rotational speed in a state where water is accumulated in the tank 4 (the drain valve 34 is closed).

  The drying course is a course in which, after detecting the weight, heat drying, finishing, and blowing are executed in order. In the weight detection operation, the rotating tub 6 is rotated after the final dehydration process, and the drying load amount (moisture amount) of the material to be dehydrated (laundry after dehydration) is estimated based on the electrical load of the motor 12 or the rotation state of the rotating tub 6. To do. In the heating and drying operation, the heater 24 generates heat, the fan 21 is rotated by the fan motor 23, hot air is supplied into the tub 4, and the rotating tub 6 and the pulsator 10 are appropriately rotated, thereby washing the laundry. Dry. In the finishing operation, the amount of heat generated by the heater 24 is lowered, and the rotational speed of the fan 21 is also lowered. The air blowing operation (soft keep) rotates the fan 21 in a state where the heater 24 is turned off. Dryness is detected in the second half of the heat drying operation. Dryness detection is determined based on the detected temperatures of the exhaust temperature sensor 58 and the water tank temperature sensor 59.

The washing / drying course (washing / drying operation) is a course for sequentially executing the above-described washing course and drying course.
In the above configuration, when the user selects an arbitrary course and presses the start / pause switch 43, the control device 39 starts operation of the selected course. During this operation, when the user presses the start / pause switch 43 in order to avoid, for example, the operation in the power consumption peak time zone, the control device 39 stops the operation being executed and The time at which the stop has occurred is stored, and “3:00” is displayed on the time display unit 56a of the display unit 56 as the interrupting time, for example, as shown in FIG. This display is a display that the operation is automatically resumed after 3 hours.

  The control device 39 determines that the operation is automatically restarted after 3 hours when a predetermined time, for example, 30 seconds elapses from the time display. If the user operates the operation dial 55 before 30 seconds have elapsed since the time display, the control device 39 changes and displays the display time of the time display unit 56a based on the signal from the operation dial 55. . When 30 seconds have elapsed from the changed display, the interruption time is determined.

  The control device 39 automatically restarts operation when a set interruption time (for example, 3 hours) has elapsed. At this time, as shown in FIG. 5, as a restart process when the operation is temporarily interrupted during the washing process in the washing course, the control device 39 performs the washing operation regardless of the stage of the washing process. Start over from the beginning (step S1).

  When it is temporarily interrupted during the washing process, the laundry in the rotating tub 6 is left in a state where it is left in the washing liquid containing the detergent for a long time. If the washing time is interrupted when the remaining 30 seconds, and if the washing operation is performed only for the remaining 30 seconds after the operation is resumed, there is a possibility that the stains reattached to the laundry may not be removed due to the application. In this regard, as in this embodiment, when operation is temporarily interrupted in the middle of the washing process, the set washing time is ensured by restarting the washing operation from the beginning after resuming operation, regardless of the stage where the operation is interrupted. In addition, the laundry can be washed sufficiently and the finish can be improved.

(Second Embodiment)
FIG. 6 shows a second embodiment. The second embodiment is different from the first embodiment described above in the following points. The control device 39 determines whether or not the remaining time of the washing time is less than 3 minutes as a resumption process when the operation is resumed after being temporarily interrupted in the middle of the washing process (step S2). In accordance with “NO”, the process proceeds to step S3, and after the washing operation is performed for the set remaining time, the process proceeds to the next step. If it is determined in step S2 that the remaining washing time is less than 3 minutes, the process proceeds to step S4 according to “YES”, and the washing operation is performed for a minimum fixed time, in this case, 3 minutes. Proceed to the next process.

  In this embodiment, when the operation is temporarily interrupted during the washing process, the washing operation is performed for a minimum fixed time (in this case, 3 minutes) after the operation is resumed. If the washing time is interrupted when the remaining 30 seconds, and if the washing operation is performed only for the remaining 30 seconds after resuming operation, there is a possibility that the stains that have re-attached to the laundry may not be removed due to the application. According to the present embodiment, the laundry can be washed well and the finish can be improved by performing the washing operation for a minimum fixed time (3 minutes) after restarting the operation.

(Third embodiment)
FIG. 7 shows a third embodiment. The third embodiment is different from the above-described second embodiment in the following points. The control device 39 is configured to change the minimum washing operation time after the restart according to the length of the interruption time as a restart process when the operation is resumed after being temporarily interrupted during the washing process.

  Specifically, the control device 39 first determines whether or not the interruption time is 30 minutes or less (step S5). If the interruption time is 30 minutes or less, the process proceeds to step S6 according to “YES”, and the minimum operation time is reached. Is set to 2 minutes, and then the process proceeds to step S7. If it is determined in step S5 that the interruption time is longer than 30 minutes and is not 30 minutes or less, the process proceeds to step S8 according to “NO” to determine whether or not the interruption time is 2 hours or less. If it is determined that the interruption time is 2 hours or less (30 minutes to 2 hours), the process proceeds to step S9 according to “YES”, and after the minimum operation time is set to 3 minutes, the process proceeds to step S7. If it is determined in step S8 that the interruption time is longer than 2 hours and is not less than 2 hours, the process proceeds to step S10 according to “NO”, and it is determined whether or not the interruption time is 4 hours or less. If it is determined that the interruption time is 4 hours or less (2 hours to 4 hours), the process proceeds to step S11 according to “YES”, and the minimum operation time is set to 4 minutes, and then the process proceeds to step S7. If it is determined in step S10 that the interruption time is longer than 4 hours and not less than 4 hours, the process proceeds to step S12 according to “NO”, and the minimum operation time is set to 5 minutes, and then the process proceeds to step S7.

  In step S7, the control device 39 determines whether or not the remaining washing time after the restart of operation is less than the set minimum operation time (the time set in steps S6, S9, S11, and S12). If it is less, the process proceeds to step S13 according to “YES”, and after performing the washing operation for the set minimum operation time, the process proceeds to the next process. In Step S7, when it is determined that the remaining time of the washing time after the restart of operation is equal to or longer than the set minimum operation time, the washing operation for the remaining time is performed, and then the process proceeds to the next step.

  In this embodiment, as a restart process when the operation is resumed after being temporarily interrupted in the middle of the washing process, the minimum operation time of the washing after the restart is changed according to the length of the interruption time. Since the state of setting changes according to the length of the interruption time, the laundry can be washed well by changing the minimum operation time of the washing after the restart according to the length of the interruption time.

(Fourth embodiment)
FIG. 8 shows a fourth embodiment. The fourth embodiment is different from the first to third embodiments described above in the following points. The control device 39 is configured to change the number of times of rinsing in the rinsing process after resumption according to the length of the interruption time as a resumption process when resuming the operation after being suspended in the middle of the washing process.

  Specifically, the control device 39 first determines whether or not the interruption time is 2 hours or less (step S15). If it is 2 hours or less, the control device 39 proceeds to step S16 according to “YES” and sets the number of times of rinsing. After the setting of adding once is performed, the process proceeds to step S17. If the interruption time is longer than 2 hours in step S15, the process proceeds to step S18 according to “NO” to determine whether or not the interruption time is 4 hours or less. If the interruption time is 4 hours or less (2 hours to 4 hours), the process proceeds to step S19 according to “YES”, and after setting to increase the number of times of rinsing twice, the process proceeds to step S17. In step S18, when the interruption time exceeds 4 hours, the process proceeds to step S20 according to “NO”, and after setting the number of times of rinsing to be increased by 3 times, the process proceeds to step S17.

  In step S17, the control device 39 adds the number of rinses set in advance in the rinse process and the number of rinses added in steps S16, S19, and S20, and determines whether or not the total number of rinses exceeds four. If it is determined that it exceeds four times, the process proceeds to step S21 according to “YES”. In step S21, the number of times of rinsing is set to the upper limit of 4 times, and the process proceeds to the next step. In step S17, if the number of rinses does not exceed 4, the process proceeds to the next step with the set number of rinses.

  In the case of a standard laundry course, the number of rinses is about two. In the case of FIG. 4, the total number of times of shower rinsing is one, and rinsing is twice. If it is temporarily interrupted during the washing process, the detergent that has soaked into the laundry may not be removed by only the normal rinsing operation. When the operation is temporarily interrupted during the washing process as in this embodiment, after the operation is resumed, it is possible to prevent the laundry detergent residue as much as possible by increasing the number of times of rinsing in the rinsing process.

  Further, in the present embodiment, the number of times of rinsing that is increased after restarting operation is changed according to the length of the interruption time, so that it is possible to cope with the length of the interruption time. However, the upper limit of the number of times of rinsing is 4 times, so that the number of times of rinsing can be prevented from increasing unnecessarily.

(Fifth embodiment)
FIG. 9 shows a fifth embodiment. The fifth embodiment is different from the first to fourth embodiments described above in the following points. The control device 39 determines whether there is a shower rinsing setting in the rinsing process of the washing course to be executed as a resumption process when the operation is resumed after being temporarily interrupted during the washing process (step S22). If there is a shower rinsing setting, the process proceeds to step S23 in accordance with “YES”, and the shower rinsing in the rinsing process is changed to the rinsing, and then the process proceeds to the next process. If there is no shower rinsing setting in step S22, the process proceeds to the next step as it is according to "NO".

  If the process is temporarily interrupted during the washing process, the shower rinsing operation may not allow the detergent soaked in the laundry to fall off. Therefore, in the rinsing operation, since the rinsing operation is performed in a state where water is accumulated in the tub 4 as in the washing operation, the detergent soaked in the laundry can be rinsed out well, and the detergent remaining in the laundry can be prevented. .

  In the present embodiment, when the operation is performed with the setting including the shower rinsing operation in the rinsing process, and when the operation is temporarily interrupted during the washing process, the shower rinsing operation is stopped and the rinsing operation is performed after the operation is resumed. As a result, it is possible to satisfactorily rinse out the detergent soaked in the laundry due to the temporary interruption, and the laundry detergent remaining in the laundry can be prevented. In the present embodiment, the rinsing operation is performed twice in the rinsing process.

(Sixth embodiment)
FIG. 10 shows a sixth embodiment. The sixth embodiment is different from the first to fifth embodiments described above in the following points. The control device 39 restarts the dehydration operation from the beginning as a restart process when the operation is resumed after being temporarily interrupted during the dehydration operation in the dehydration process (final dehydration) (step S24).

  When the dehydrating operation is resumed after being temporarily interrupted during the dehydrating operation, the rotation speed of the rotating tub 6 is increased from zero. If the remaining time of the dehydrating operation after resumption is short, the dehydrating operation time may end before reaching the top rotation speed for dehydration. In such a case, compared with the normal time when there is no temporary interruption, the rotational speed is different for the start-up period, so that the dewatering performance is reduced accordingly.

  In this regard, if the suspension is temporarily interrupted during the dewatering operation as in this embodiment, the dewatering operation is restarted from the beginning after the operation is restarted, so that the set dewatering operation time is secured and the dewatering performance is reduced. Can be prevented. This control can be applied not only to the final dehydrating operation but also to the intermediate dehydrating operation in the rinsing process.

(Seventh embodiment)
FIG. 11 shows a seventh embodiment. The seventh embodiment is different from the above-described sixth embodiment in the following points. The control device 39 first supplies water to the set water level in the tub 4 to wet the laundry as a resumption process when the operation is resumed after the suspension during the dehydration operation in the dehydration process (final dehydration) (step S25). ). At this time, the drain valve 34 is closed. Then, the drain valve 34 is opened to drain water (step 26), and then the dehydration operation is started again (step S27).

  When temporarily interrupted during the dehydration operation, the laundry in the rotating tub 6 remains attached to the inner surface of the rotating tub 6. If the operation is continued for a long time until the operation is resumed, the laundry is more likely to wrinkle than during normal dehydration. In particular, in the case of a course in which preheat dehydration is performed before the drying operation, since warm air is supplied into the tub 4, there is a situation that wrinkles are more likely to wrinkle on the laundry.

  In this respect, as in this embodiment, when the operation is temporarily interrupted during the dehydration operation, after restarting the operation, water is supplied into the tub 4 to wet the laundry, and then the dehydration operation is performed again. It becomes possible to prevent the performance from being lowered.

(Eighth embodiment)
FIG. 12 shows an eighth embodiment. The eighth embodiment is different from the first to seventh embodiments described above in the following points. The control device 39 adds a predetermined drying time to the remaining drying time after the operation is resumed as a restart process when the operation is resumed after being temporarily interrupted during the drying process, and according to the length of the interruption time. Change the drying time.

  Specifically, the control device 39 first determines whether or not the interruption time is 30 minutes or less when the operation is resumed after being temporarily interrupted during the drying process (step S30). In step S31, the process proceeds to step S31. After setting for adding the drying time of 30 minutes to the remaining drying time, the process proceeds to step S32 to execute the drying operation. In the drying operation, the drying operation is performed for the total time of the remaining drying time and the added drying time.

  If the interruption time is longer than 30 minutes in step S30, the process proceeds to step S33 according to “NO” to determine whether or not the interruption time is 2 hours or less. When it is determined that the interruption time is 2 hours or less (30 minutes to 2 hours), the process proceeds to step S34 according to “YES”, and the setting is made to add the drying time of 50 minutes to the remaining drying time. Then, it transfers to step S32 and performs a drying operation.

  If the interruption time is longer than 2 hours in step S33, the process proceeds to step S35 according to “NO”, and it is determined whether or not the interruption time is 4 hours or less. If it is determined that the interruption time is 4 hours or less (2 hours to 4 hours), the process proceeds to step S36 according to "YES", and a setting is made to add a drying time of 70 minutes to the remaining drying time. Then, it transfers to step S32 and performs a drying operation. If the interruption time is longer than 4 hours in step S35, the process proceeds to step S37 according to “NO”, and after setting for adding the drying time of 90 minutes to the remaining drying time, the process proceeds to step S32. Execute dry operation.

  When temporarily interrupted during the drying process, the supply of hot air into the tank 4 is also stopped, and the temperature in the tank 4 decreases. Then, since subsequent drying detection is not performed accurately, the laundry may not be sufficiently dried even after the drying operation is finished.

  In this regard, according to the present embodiment, after the suspension during the drying process, after restarting the operation, a predetermined drying time is added to the remaining drying time to perform drying, thereby preventing the laundry from being dried. It can be avoided. In addition, by changing the drying time to be added according to the length of the interruption time, it is possible to perform control corresponding to the interruption time, and to further avoid the situation where the laundry cannot be dried.

(Ninth embodiment)
13 and 14 show a ninth embodiment. When temporarily interrupted during the drying process, as described above, the supply of hot air into the tank 4 is also stopped, and the temperature in the tank 4 decreases. If it becomes so, subsequent drying detection will not be performed correctly and laundry may not be dried enough. However, if it is interrupted just before the end of the drying process, there may be no problem even if the drying time after restarting is not changed. Thus, the appropriate additional drying time after the restart varies depending on the timing of the suspension in the drying process. Therefore, in the present embodiment, the additional drying time is changed depending on the timing at which the drying process is temporarily suspended.

  FIG. 14 shows an example of a plurality of sections and contents in the drying process. The section is divided into a heating section, a drying detection section, a finishing section, and an air blowing section (soft keep). Among these, in the heating section, the heater output is “strong” and the rotational speed of the fan is 3500 rpm. In the drying detection section, the heater output is “strong” and the rotation speed of the fan is 4500 rpm, which is higher than that in the heating section. In the finishing section, the heater output is “weak” and the rotational speed of the fan is 2500 rpm. And in a ventilation area, a heater cuts off electricity and the rotational speed of a fan is 3500 rpm.

  When the operation is resumed after being temporarily interrupted during the drying process, the control device 39 first determines at which timing (section) the process is interrupted as shown in FIG. 13 (steps S38 and S39). , S40). If interrupted during the heating section, the process proceeds to step S41 according to “YES” in step S38, and after setting to add a drying time of 40 minutes to the remaining drying time, the process proceeds to step S42 and set. Perform the drying operation with the corrected drying time. If interrupted during the drying detection section, the process proceeds to step S43 according to “YES” in step S39, and after setting to add a drying time of 60 minutes to the remaining drying time, the process proceeds to step S42. The drying operation is executed with the re-dried drying time.

  If interrupted during the finishing section, the process proceeds to step S44 according to “YES” in step S40, and after setting to add a drying time of 20 minutes to the remaining drying time, the process proceeds to step S42 and set. Perform the drying operation with the corrected drying time. In addition, when interrupted during the blowing section, the process proceeds to step S45 according to “NO” in step S40, and after setting to not add the drying time, the process proceeds to step S42, and the drying operation is performed with the remaining drying time set. Execute. In this embodiment, the additional time (60 minutes) when interrupted during the drying detection period is longer than the additional time (40 minutes) when interrupted during the heating period. This is for the purpose of making the dryness detection more accurate because it is expected that the dryness detection will not be accurately performed after the restart.

  According to the above-described embodiment, the additional drying time after the restart is changed depending on at which timing of the drying process, the drying according to the situation can be performed, and an appropriate drying finish can be obtained. it can.

(10th Embodiment)
FIG. 15 shows a tenth embodiment. When temporarily interrupted during the drying process, as described above, the supply of hot air into the tank 4 is also stopped, and the temperature in the tank 4 decreases. If it becomes so, subsequent drying detection will not be performed correctly and laundry may not be dried enough. Therefore, in the present embodiment, after the drying operation is restarted and the drying process (drying operation) is once completed, an additional drying operation can be performed.

  Specifically, as shown in FIG. 15, the control device 39 finishes the drying operation as an additional drying process (step S <b> 46), and then whether or not the lid 16 has been opened and closed by 10 minutes. Is determined (steps S47 and S48). Open / close detection of the lid 16 is performed by detecting a lid switch (not shown). If opening / closing of the lid 16 is not detected before 10 minutes have passed, the power is turned off.

  When the user opens and closes the lid 16 by 10 minutes and the control device 39 detects this, the process proceeds to step S49 according to “YES” in step S47 to determine whether or not there has been a temporary interruption process during the drying operation. . If there is a temporary interruption process, the process proceeds to step S50 according to “YES” in step S49, and the additional drying time 30 minutes is displayed on the time display unit 56a of the display unit 56. Thereafter, the control device 39 determines whether or not the start / pause switch 43 has been pressed until 10 minutes have passed (steps S51 and S52). If it is determined that the start / pause switch 43 has been pressed before 10 minutes have elapsed, the process proceeds to step S53 according to “YES” in step S51, and an additional drying operation of 30 minutes is executed.

  If the start / pause switch 43 is not pressed after 10 minutes after the additional drying time of 30 minutes is displayed in step S50, the control device 39 determines that the user does not intend to perform additional drying. In step S52, the power is turned off according to “YES”. If it is determined in step S49 that there has been no temporary interruption process during the drying operation, the process proceeds to step 54 according to “NO”, and the power is turned off after 10 minutes.

  In the above-described embodiment, after the drying operation is completed, additional drying can be performed at the user's will, and when the user determines that the drying is not sufficient, it can be compensated. Thereby, even when the operation is resumed after being temporarily interrupted during the drying operation, the finished state can be improved.

(Eleventh embodiment)
FIG. 16 shows an eleventh embodiment. In the tenth embodiment described above, the drying time added when there is a temporary interruption during the drying operation is limited to a certain time of 30 minutes (see step S50 in FIG. 15). However, the longer the interruption time, the lower the temperature in the tub 4, so it takes more time to raise the temperature in the tub 4 after restarting the operation, and the drying condition of the laundry at the end of the operation also changes. . Therefore, even if additional drying is performed, there is a possibility that the laundry will not dry sufficiently. Therefore, in the present embodiment, in the process of setting the additional drying time in step 50 of FIG. 15, as shown in FIG. 16, the additional drying time is changed according to the interruption time of the drying time.

  Specifically, the control device 39 first determines whether or not the interruption time is 30 minutes or less (step S55). If it is determined that the interruption time is 30 minutes or less, the process proceeds to step S56 according to “YES”. After the additional drying time is set to 30 minutes, the process proceeds to the next process. If the interruption time is longer than 30 minutes in step S55, the process proceeds to step S57 according to “NO” to determine whether or not the interruption time is 2 hours or less. If it is determined that the interruption time is 2 hours or less (30 minutes to 2 hours), the process proceeds to step S58 according to “YES”, and after the additional drying time is set to 50 minutes, the process proceeds to the next process.

  If the interruption time is longer than 2 hours in step S57, the process proceeds to step S59 according to "NO" to determine whether or not the interruption time is 4 hours or less. When it is determined that the interruption time is 4 hours or less (2 hours to 4 hours), the process proceeds to step S60 according to “YES”, and after the additional drying time is set to 70 minutes, the process proceeds to the next process. In step S59, when the interruption time is longer than 4 hours, the process proceeds to step S61 according to “NO”, and after the additional drying time is set to 90 minutes, the process proceeds to the next process.

According to the above-described embodiment, it is possible to further improve the drying state by changing the additional drying time according to the length of the interruption time interrupted during the drying operation.
(Other embodiments)
In the tenth embodiment of FIG. 15, when the additional drying time is displayed in step 50, the additional drying time may be arbitrarily changed and set by the user. In this case, the dry state can be adjusted to the user's preference.

  For example, the following specifications may be used as a specification for temporarily interrupting the washing operation or the washing / drying operation and automatically restarting the operation after a predetermined time. When the power consumption peak time zone is set in advance in the control device and the user sets the reserved operation, when the power consumption peak time zone is reached during the operation, the control device temporarily stops the operation, A specification is considered that the operation is automatically restarted when the power consumption peak time period has passed.
