The control device 19 accesses a predetermined external site, and information on the power supply / demand of a power supply source such as a power company, for example, the power supply / demand ratio (power usage rate) Rate), “stable supply / demand situation”, “slightly demand / supply situation”, “severe supply / demand situation”, etc. Get power supply and demand tight warnings.

  And the control apparatus 19 sets the index | exponent (henceforth an electric power supply-and-demand index) which becomes large so that electric power supply-and-demand becomes tight based on the information regarding the acquired electric power supply-and-demand. As a specific example, if the information acquired from the outside is the power supply / demand ratio, the power supply / demand ratio is set as the power supply / demand index. If the information obtained from the outside is a rank determined according to the power supply and demand, the rank is indexed, for example, “1” for “stable supply and demand”, “slightly demand and supply” For example, “2” is set as the power supply and demand index. If the information acquired from the outside is a power supply / demand tight alarm issued by the government, “1” is set if there is no power supply / demand tight warning, and “2” is set if there is a power supply / demand tight warning. In other words, in the present embodiment, the control device 19 functions as an acquisition unit that acquires information on the power supply / demand of the power supply source from the outside, and the power that increases as the power supply / demand tightens based on the acquired information on the power supply / demand It also functions as an index setting means for setting the supply and demand index.

  As shown in FIG. 5, the washing course executed by the control device 19 includes a weight detection process, a washing operation (water supply and washing processes), and a rinsing operation (drainage, dehydration, shower pouring, dehydration, water supply, and pool rinsing). ), And dehydration operation (each process of drainage and dehydration). In the present specification, the washing operation and the rinsing operation are collectively referred to as a washing operation.

  The weight detection process before the washing operation described above is performed by rotating the agitator 12 in a state where the laundry is stored before supplying the washing water to the water tank 2 and detecting the electric load applied to the motor 13a. Detect weight.

  The drainage process is performed by opening the drainage valve 16, and the water supply process is performed by opening the water supply valve 40 and supplying water to a predetermined water level. In the washing process, the stirring member 12 is rotated forward and backward at a predetermined rotational speed. In the dehydration process, the rotary tank 10 is rotated in one direction at a predetermined dehydration rotation speed. Shower water is poured (supplied) into the rotary tank 10 while rotating the rotary tank 10. In the reservoir rinsing process, the agitator 12 is rotated forward and backward at a predetermined rotational speed with water stored in the water tank 2.

  The drying course is a course for executing a weight detection process, a drying operation (each process of tank rotation, stirring, tank rotation, stirring, and tank rotation) and a soft keeping process.

  In the tank rotation process, the fan 41 and the heater 42 are driven to rotate the rotating tank 10 at a predetermined speed while supplying warm air to the rotating tank 10. In the stirring process, the supply of warm air is stopped and the stirring body 12 is rotated forward and backward.

  In the soft keeping process, only the fan 41 is driven to supply normal-temperature wind to the rotating tank 10, and the rotating tank 10 is appropriately rotated in the forward and reverse directions.

  The washing / drying course is a course for executing the above-described washing course and the drying course in order.

  After such a control device 19 has selected any course from the above-described washing course, drying course, and washing / drying course by operating various switches 23 to 36 provided on the operation panel 22, the control device 19. When the power saving switch 36 is operated, the selection of the power saving operation, whether the peak cut operation or the peak shift operation is executed when the power saving mode is executed, and the maximum power consumption value during the peak cut operation are set. .

  In the power saving operation, the standard mode is executed when the information on the power supply / demand of the power supply source acquired from the outside by the control device 19 is the same as the predetermined condition or when the power supply / demand is not tightened from the predetermined condition, In this embodiment, the power supply / demand index is set based on information acquired from the outside by the control device 19, and the standard mode is selected when the power supply / demand index is equal to or less than a predetermined value. When the power supply / demand index is greater than a predetermined value, the power saving mode is executed. That is, in the present embodiment, a predetermined condition is whether or not the power supply and demand index set by the control device 19 is greater than a predetermined value.

  Specifically, as shown in FIG. 6, first, when any one of the various switches 23 to 36 is operated in step S <b> 1, course selection according to the operation, selection of driving, and reservation driving are performed. Settings, power saving operation settings, etc. are executed (step S2). After that, when the start switch 25 is operated in step S3, the operation proceeds to step S4 to start the operation of the washing machine 1, and the start switch 25 must be operated. Return to step S1.

  When the operation of the washing machine 1 starts, the weight detection process is executed in step S4, and then in step S5, it is determined whether or not the power saving operation is set in step S2. If the power saving operation is not set, the process proceeds to step S15, and the course or operation is performed with predetermined contents determined in advance from the weight of the laundry detected in the weight detection process and the selected course or operation. Run. When the power saving operation is set, the process proceeds to step S6.

  In step S6, it is determined whether or not the power supply / demand index set by the control device 19 based on the information on the power supply / demand of the power supply source acquired from the outside is larger than a predetermined value. If the power supply / demand index is less than or equal to a predetermined value in step S6, the process proceeds to step S10, and predetermined operation contents predetermined from the weight of the laundry detected in the weight detection process and the selected course or operation are performed. After executing the course or driving in the standard mode, the process proceeds to step S11. If the power supply / demand index is larger than the predetermined value in step S6, the process proceeds to step S7.

  In step S7, it is determined whether or not the peak shift operation is set in step S2. If the peak cut operation is set, the process proceeds to step S8, and if the peak cut operation is not set, that is, the peak shift operation is performed. If set, the process proceeds to step S9.

  In step S8, the power saving mode in which the peak cut operation for executing the course or the operation selected in step S2 is executed while suppressing the power consumption from the standard mode is executed, and the process proceeds to step S11.

  Specifically, in the washing operation and the rinsing operation, the stirrer 12 is intermittently rotated in both forward and reverse directions. At this time, the time for rotating the stirrer 12 during the peak cut operation (that is, the ON time limit) is standard. The time is shortened compared to the mode, and the time for stopping the stirring body 12 (that is, the OFF time) is lengthened compared to the standard mode. In the dehydration operation, the rotating tank 10 and the stirring body 12 are rotated in one direction. At this time, the number of rotations during the peak cut operation is made smaller than that in the standard mode. In the drying operation, the output of the heater 42 in the peak cut operation is made smaller than in the standard mode.

  In the peak cut operation as described above, the time (operation time) for executing the washing operation and the dehydration operation may be set longer than that in the standard mode. As described above, in the peak cut operation, the power consumption can be suppressed without degrading the performance of the washing operation and the dewatering operation by extending the operation time as compared with the standard mode. In the drying operation, the rotational speed of the fan 41 may be reduced in addition to the heater 42.

  Furthermore, in step S2, the power consumption value during the washing operation, the dehydration operation, and the drying operation is suppressed from the standard mode so that the power consumption value during the peak cut operation set in step S2 does not exceed the maximum power consumption value. The selected course or driving may be executed.

  In step S11, it is determined whether or not all the courses or driving set in step S2 have been completed. If all the courses or driving have been completed, the operation of the washing machine 1 is stopped. Until the operation ends, the control device 19 continues to determine whether or not the power supply and demand index set based on the information on the power supply and demand of the power supply source acquired from the outside is larger than a predetermined value.

  In step S9, it is determined whether or not the washing machine 1 is in operation. If it is stopped, the process proceeds to step S12, and if it is in operation, the process proceeds to step S13.

  In step S12, the power saving mode in which the peak shift operation in which the course or operation selected in step S2 is not performed and the operation of the washing machine 1 is temporarily stopped for a predetermined period is performed is executed, and the process proceeds to step S6. The peak shift operation for temporarily stopping the operation of the washing machine 1 is continuously performed until the power supply / demand index set based on the information on the power supply / demand of the power supply source acquired from the outside becomes equal to or less than a predetermined value (step S6), When the power supply / demand index becomes a predetermined value or less, the mode is shifted from the power saving mode in which the peak shift operation is performed to the standard mode, and the selected course or operation is executed (step S10).

  In step S13, it is determined whether the operation being performed is a drying operation. If the running operation is a drying operation, the process proceeds to step S12, where the drying operation is stopped halfway and the peak shift operation is executed. If the running operation is not a dry operation, that is, if it is a washing operation or a dehydrating operation, the operation proceeds to step S14 and continues until the running operation is completed. Proceeding to S12, the washing machine 1 is stopped without performing the next operation, and the peak shift operation is executed.

  During peak shift operation, the fact that the peak shift operation is being performed may be displayed on the display 37, for example, so that the user can be notified of this. Sleep that restricts functions other than the operation of the switches 23 to 36, such as notifying that the peak shift operation is being performed, then accepting only the operations of the various switches 23 to 36, and stopping the display of the display 37 You may enter mode.

  In the present embodiment described above, the control device 19 reduces the power consumption when the power supply / demand index set based on the information on the power supply / demand of the power supply source such as the power company acquired from the outside is larger than the predetermined value. Since the operation or the peak shift operation is performed, the operation content is changed according to the power supply / demand situation, and the power consumption can be suppressed during the time when the power supply / demand is tight, which contributes to the solution of the power shortage.

  In the present embodiment, when the power supply and demand index is larger than a predetermined value, the user can set whether to perform peak cut operation or peak shift operation, so the user selects the degree of power saving. And convenience can be improved.

  Moreover, in this embodiment, since it shifts to the sleep mode which restrict | limits some functions, such as accepting only operation of various switches 23-36 and restricting other operation during peak shift operation, during peak shift operation, Power consumption can be minimized.

  Further, in the present embodiment, when the peak shift operation is performed by shifting from the standard mode to the power saving mode during the washing operation or the dehydrating operation, the operation of the washing machine 1 is stopped after the running operation is completed, and the power saving mode It is possible to operate efficiently without the need for redundant washing and dehydrating operations when returning to the standard mode from the current mode. The drying operation with large electric power can be stopped in the middle, and the power consumption by the washing machine 1 can be greatly reduced to contribute to the solution of power shortage.

  In the present embodiment described above, the power supply / demand index is set based on the information on the power supply / demand of the power supply source acquired from the outside, and whether or not the set power supply / demand index is larger than a predetermined value is determined based on the standard mode and the power saving. The predetermined condition for determining the mode to be executed from the mode is set, but the present invention is not limited to this. For example, without setting the power supply and demand index from the information acquired from the outside, such as a power supply and demand tight alarm The power saving mode and the standard are set based on whether or not the predetermined information is acquired from the outside, such as executing the power saving mode when the predetermined information is acquired and executing the standard mode when the predetermined information is not acquired. The mode may be switched and executed.

(Example of change)
Next, a modified example of the present embodiment will be described. In the peak cut operation of the present embodiment described above, the ON time period during the peak cut operation is set shorter than the standard mode during the washing operation, the OFF time is set longer than the standard mode, and the dehydration operation is performed. While the description has been given of the case where the rotational speed of the rotary tank 10 and the stirring body 12 is set to be smaller than that in the standard mode and the output of the heater 42 is set to be smaller than that in the standard mode during the drying operation. In addition to this, in addition to this, the operation content of the standard mode may be changed as follows as the peak cut operation.

  For example, when water is supplied while rotating the stirrer 12 in the washing operation during execution of the standard mode, water may be supplied while the stirrer 12 is stopped in the power saving mode in which the peak cut operation is performed. By changing the operation content in this way, power consumption can be suppressed, which can contribute to the elimination of power shortage.

  In addition, the amount of water less than the water level required for operation (regulated water level) in the washing operation during the standard mode is supplied, and then the agitator 12 is rotated while temporarily stopping the water supply. When supplying water in multiple times until the specified water level is reached by repeating the rotation, water is supplied to the specified water level at once without repeating the water supply and the rotation of the stirrer 12 in the power saving mode in which the peak cut operation is performed. Also good. By changing the operation content in this way, power consumption can be suppressed, which can contribute to the elimination of power shortage.

  In addition, more specified water levels may be set in the case of performing the washing operation in the power saving mode in which the peak cut operation is performed than in the specified water level necessary for the washing operation when executing the standard mode. By changing the operation content in this way, the movement of the laundry such as clothes becomes smooth during the washing operation and the load on the motor 13a is reduced, so that the power consumption can be suppressed and the power shortage can be solved. .

  Further, regarding the operation content of the power saving mode in which the peak cut operation is performed, the process of supplying water to the water tank 2 while stopping the agitator 12 during the accumulation process of the rinse operation and causing the predetermined amount of washing water to overflow from the water tank 2 is performed 1 The operation content of the standard mode may be changed so as to be performed once or multiple times. By changing the operation content in this way, it is possible to reduce the concentration of detergent in the laundry at an early stage after the end of the washing operation and to shorten the rinsing operation, thereby reducing power consumption and contributing to the elimination of power shortage. be able to.

  In the power saving mode in which the peak cut operation is performed as compared with the standard mode, the number of rinsing operations may be reduced. By changing the operation content in this way, power consumption can be suppressed, which can contribute to the elimination of power shortage.

  Further, in the power saving mode in which the peak cut operation is performed, a control for repeatedly supplying and draining water to the water tank 2 may be added after completion of the washing operation or during the rinsing operation. By changing the operation content in this way, it is possible to reduce the concentration of detergent in the laundry at an early stage after the end of the washing operation and to shorten the rinsing operation, thereby reducing power consumption and contributing to the elimination of power shortage. be able to.

  In addition, the number of dehydration operations in the power saving mode in which the peak cut operation is performed may be set to a smaller number than the standard mode. By changing the operation content in this way, power consumption can be suppressed, which can contribute to the elimination of power shortage.

  Further, in the power saving mode in which the peak cut operation is performed, in the drainage process performed in the rinsing operation or the dewatering operation, the drainage time, that is, the time during which the drainage valve 16 is kept open after the water level sensor detects the lower limit value (reset water level). It may be set longer than the standard mode. By changing the operation content in this way, the detergent concentration in the laundry can be reduced at an early stage after the end of the washing operation, reducing the time for the rinsing operation without reducing the rinsing performance and reducing the power consumption. Can be suppressed.

(Second Embodiment)
Next, a second embodiment will be described. In the present embodiment, when the execution time zone in which the operation of the washing machine 1 is executed does not overlap with the power saving time zone, the standard mode is executed, and when the execution time zone overlaps with the power saving time zone Execute power saving mode.

  Specifically, the control device 19 has a built-in clock means and can recognize the current time. For example, when the power-saving switch 36 is pressed for a predetermined time or longer, the time during which the power consumption increases in one day. The band (power saving time zone) can be input. When the power saving switch 36 is further pressed after the power saving switch 36 is pressed for a long time, the start time of the power saving time zone is input according to the number of times, and the input of the start time is determined by operating the reservation switch 35. The end time of the power saving time zone is input according to the number of operations of the switch 36, and the input of the end time is confirmed by operating the reservation switch 35.

  The control device 19 stores the power saving time zone as a recognition means for recognizing the power saving time zone based on the start time and the end time of the power saving time zone thus input. The power saving time zone may be input other than the above-described operation, or may be stored in the memory of the control device 19 in advance by the manufacturer.

  When the power saving operation is set, the control device 19 performs the washing operation and the dehydration in the standard mode when the time for executing the operation of the washing machine 1 is not included in the power saving time zone recognized as described above. A driving operation or a drying operation is performed, and when included in the power saving time period, a washing operation, a dehydrating operation, or a drying operation is performed in a power saving mode of either a peak cut operation or a peak shift operation.

  In the case of this embodiment, the power consumption of the washing machine 1 can be suppressed during a time period in which power supply and demand is tight with a simple configuration without being connected to the external network 50.

  In addition, except the above-mentioned structure and effect, it is the same as that of 1st Embodiment, and detailed description is abbreviate | omitted.

(Third embodiment)
Next, a third embodiment will be described. In the present embodiment, when the power saving operation is set, the standard mode is executed when the detected temperature of the room temperature sensor 52 is equal to or lower than a predetermined value, and the detected temperature Tr of the room temperature sensor 52 is higher than the predetermined value Tth (Tr> The power saving mode is executed at (Tth).

  In the present embodiment, since it is determined whether the washing machine 1 is in a time zone in which power supply and demand is tight from the temperature of the installation atmosphere, the power consumption of the washing machine 1 is reduced in a time zone in which power supply and demand is tight with a simple configuration. Can be suppressed.

  In the present embodiment, the predetermined value Tth for switching between the standard mode and the power saving mode may be larger during the drying operation than during the washing operation. Thus, by changing the predetermined value Tth between the drying operation and the washing operation, even if the temperature of the installation atmosphere of the washing machine 1 temporarily rises due to the heat generated from the washing machine 1 during the drying operation, it is accurate. Power consumption can be reduced during periods of tight power supply and demand.

  In the present embodiment, the predetermined value Tth for switching between the standard mode and the power saving mode may be made smaller during the drying operation than during the washing operation. In this way, by changing the predetermined value Tth between the drying operation and the washing operation, it becomes easier to execute the power saving mode in which the power consumption is suppressed in the drying operation where the power consumption is larger than the washing operation, and the power consumption is more effectively performed. Can be reduced.

  In the present embodiment, when the temperature Tr acquired by the room temperature sensor 52 during execution of the power saving mode falls below a predetermined value Tth, the mode may be shifted from the power saving mode to the standard mode. The contents can be accurately changed, and the power consumption can be suppressed during the time when power supply and demand is tight, which can contribute to the solution of power shortage.

  In addition, except the above-mentioned structure and effect, it is the same as that of 1st Embodiment, and detailed description is abbreviate | omitted.

(Fourth embodiment)
Next, a fourth embodiment will be described. In the present embodiment, when the power saving operation is set, the standard mode is executed when the detected temperature of the water temperature sensor 51 is a predetermined value or less, and the power saving mode is executed when the detected temperature of the water temperature sensor 51 is larger than the predetermined value. To do.

  In this embodiment, in order to determine whether or not the power supply / demand is tight from the temperature of the wash water supplied to the water tank 2, the simple configuration of the washing machine 1 during the time when power supply / demand is tight is determined. The power consumption can be suppressed, and the power supply / demand situation can be grasped without being affected by the installation environment of the washing machine 1.

  In addition, except the above-mentioned structure and effect, it is the same as that of 1st Embodiment, and detailed description is abbreviate | omitted.

(Other embodiments)
In the first to fourth embodiments described above, the power supply / demand index set based on the information on power supply / demand acquired from the outside, the user or a preset power saving time zone, the detection temperature of the room temperature sensor, and the water temperature sensor Although the case where the power saving mode and the standard mode are switched and executed based on any one of the detected temperatures has been described, the power saving mode and the standard mode are based on a plurality of conditions selected from the above four conditions. You may control to switch.

  At that time, when the control device 19 can acquire information on the power supply / demand of the power supply source from the outside, the control device 19 executes the control by switching between the standard mode and the power saving mode based on the power supply / demand index set from the acquired information. When the device 19 cannot obtain information on the power supply / demand of the power supply source from the outside, information other than the power supply / demand index, that is, the power saving time zone recognized by the control device 19 and the washing machine 1 detected by the room temperature sensor 51. The standard mode and the power saving mode may be switched and executed based on either the temperature of the installation atmosphere or the temperature of the washing water detected by the water temperature sensor 52. In other words, the control device 19 determines whether to switch between the standard mode and the power saving mode by giving priority to the power supply / demand index over information other than the power supply / demand index when information on the power supply / demand of the power supply source can be acquired from the outside. Good. In such a case, if the installation environment of the washing machine 1 is an environment in which information on the power supply / demand of the power supply source can be acquired from the outside, the operation content is changed appropriately according to the power supply / demand situation and the power supply / demand The power consumption of the washing machine 1 can be reduced during tight periods, and even if the installation environment of the washing machine 1 cannot obtain information on the power supply and demand of the power supply source from the outside Thus, it is possible to suppress the power consumption of the washing machine 1 during the time when power supply and demand is tight.

  As mentioned above, although embodiment of this invention was described, these embodiment was shown as an example and is not intending limiting the range of invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof as well as included in the scope and gist of the invention.
