  About the washing machine comprised as mentioned above, the operation | movement flowchart at the time of a course driving | operation is described in FIG.5 and FIG.6, and the operation | movement and an effect | action are demonstrated below. FIG. 5 shows an operation flow in the first washing tub, and FIG. 6 shows an operation flow in the second washing tub.

  The lids 105 and 205 of the first and second washing tubs are opened, and the laundry sorted by the fiber material and the color is put into the rotating drums 101 and 201 from the clothing loading ports 106 and 206, respectively ( Steps S101 and S201) After closing the lids 105 and 205, the operation units 4a and 4b for performing input settings for the first and second washing tubs and the display units 5a and 5b for displaying the input setting contents are used for the respective washing tubs. Are set (steps S102 and S202), and each operation is started (steps S103 to S104 and S203 to S204).

  The control units 1a and 1b of the control unit 112 set the optimum water level according to the amount of laundry in each of the rotary drums 101 and 201, and control the water supply unit 21 to control the inside of the rotary drums 101 and 201. Water is supplied into the water receiving tanks 102 and 202. Then, when the water level is detected by the water level detection means 10 and reaches the set water level, the water supply is terminated, the motors 104 and 204 are controlled, the rotating drums 101 and 201 are rotated, and the washing set in each washing tub is set. Do the journey. When the set predetermined washing time has elapsed (steps S105 and S205), the washing process is ended (steps S106 and S206).

  After each washing process, the drainage means 20 is controlled to drain the washing water, and after dehydration, the water supply means 21 is controlled again to supply water into the rotating drums 101 and 201 and the water receiving tanks 102 and 202. . Then, when the water level is detected by the water level detection means 10 and reaches the set water level, the water supply is terminated, the motors 104 and 204 are controlled, the rotary drums 101 and 201 are rotated, and the rinse set in each washing tub. The process is started (steps S107 and S207). When the predetermined rinsing time and the number of times of rinsing are set (steps S108 to S109, S208 to S209), the rinsing process is terminated (steps S110 and S210).

  After completion of the rinsing process, the draining means 20 is controlled to drain the water after rinsing, and each final dehydration is performed (steps S111 to S113, S211 to S213), and the operation is terminated (steps S114 and S214).

  As described above, the control units 1a and 1b of the control unit 112 sequentially perform the washing, rinsing, and dehydration processes in the same operation flow for both the first washing tub and the second washing tub. Although controlled and executed, the same process is not executed at the same timing for both washing tubs. That is, for the first washing tub, the operation flow shown in FIG. 5 is executed, and for the second washing tub, the operation flow shown in FIG. 6 is executed. In both operation flows, the selected courses a and b, the input settings a and b, the washing times a and b, the rinsing times a and b, the rinsing times a and b, and the dewatering times a and b are shown. Each can be operated under different washing courses and conditions.

  Thus, control part 1a, 1b of the control means 112 of the washing machine in this Embodiment enabled it to drive (washing, rinsing, dehydrating) each of two washing tubs on different courses and conditions. Thus, the laundry sorted according to the fiber material and color can be operated simultaneously on the washing courses and conditions suitable for each, so that the time can be effectively utilized and the total washing time can be shortened.

  In this embodiment, the controller is provided with one control unit for each of the two washing tubs, and the washing operation is performed. However, the washing operation of the two washing tubs is performed by one control unit. Also good.

(Embodiment 2)
The structure of the washing machine in the second embodiment of the present invention is the same as that in the first embodiment. The operation flow of the control means during the washing operation is also the same as that described in FIGS.

  The point that the washing machine in the present embodiment is different from that in the first embodiment is that time adjustment is performed in one or a plurality of steps of washing, rinsing, and dewatering, and the operation end time of the course is set as the first washing tub. It is the point which comprised so that it might correspond with a 2nd washing tub.

  The control units 1a and 1b of the control means 112 set the process contents of the respective washing tubs using the operation units 4a and 4b and the display units 5a and 5b of the first and second washing tubs, When the start of operation is instructed, the operation time of washing, rinsing and dehydration is adjusted, and the operation of both washing tubs is ended at the same time.

  Specific examples of the method will be described later as Embodiments 3 to 5. In addition to these, for example, the control units 1a and 1b or the user depending on the quantity and quality of the laundry put into both washing tubs. With this setting, the time and number of washing, rinsing, and dehydration for each washing tub and the operation time of the entire course (operation end time) can be predicted for the control units 1a and 1b before the start of operation. If there is a surplus, the priority of the process that is desired to be extended is taken into consideration, and the execution time of one or more processes is extended by a difference between the two washing tubs, and the operation of both washing tubs is terminated at the same time.

  For example, if the laundry is left on the inner periphery of the rotary drums 101 and 201 for a long time after dehydration, the laundry may be wrinkled or smelled. In the state where the laundry is immersed in the rinse water before the final drainage of the rinsing process (before the drainage in steps S110 and S210) before the stroke starts (before the start of steps S111 and S211), The driving | running | working which carries out difference time and operation | movement standby is also considered.

  In addition, for example, in the dehydration process, it is necessary to start up the motor from a stopped state to a high speed rotation, and stop the process as quickly as possible at the end of the process, and a considerably large current flows through the motors 104 and 204 and the motor drive circuit. A considerable temperature rise occurs. In addition, since the high-speed rotation of the rotary drums 101 and 201 generates large vibrations and operation noises, undesired phenomena such as movement of the washing machine bodies 109 and 209 and generation of noise when both the rotary drums 101 and 201 rotate at the same time at high speed. May occur. In order to suppress these, an operation in which the start of the dehydration process (steps S111 and S211) is shifted in the two washing tubs by the difference time between the two washing tubs is also conceivable.

  As described above, in the washing machine according to Embodiment 2 of the present invention, the control units 1a and 1b arranged in the respective washing tubs operate (wash, rinse, and dehydrate) the two washing tubs on different courses. The laundry can be finished at the same time in the laundry courses and washing conditions suitable for each of the textile materials and colors. Objects can be taken out at the same time, and the operability and convenience of customers can be improved in accordance with the effective use of time.

In addition, if left in the dehydrated state, there is a tendency for wrinkles and odors to adhere to the laundry. However, it is possible to take out the laundry from both washing tubs at the same time and immediately after dehydration. The occurrence of defects can be suppressed. Furthermore, the washing operation can be performed in consideration of the movement of the washing machine bodies 109 and 209 during the washing operation, the suppression of noise generation, and the like.

(Embodiment 3)
The configuration of the washing machine in the third embodiment of the present invention is the same as that in the first embodiment.

  The point that the washing machine in the present embodiment is different from that in the first embodiment is that there is a difference in the set operation time of the course of washing, rinsing, and dehydrating in the first washing tub and the second washing tub. By shifting the operation start time on the short side of the time difference and the set operation time, the operation end time is controlled so as to coincide between the first washing tub and the second washing tub. .

  The control units 1a and 1b of the control means 112 set the process contents of the respective washing tubs using the operation units 4a and 4b and the display units 5a and 5b of the first and second washing tubs, When the start of operation is instructed, the start time of the course for which the shorter operation time is set is automatically delayed so that the end of the operation is adjusted to the same time.

  As shown in FIGS. 7 and 8, the operation flow of the washing machine control means in the present embodiment is the same as that shown in FIGS. 7 and 8, with the start button ON (steps S103 and S203) in the operation flow shown in FIGS. During the start of the washing process (steps S104 and S204), an operation flow for automatically delaying the start time of the set course of the washing tub with the shorter set operation time is inserted.

  When the start button is turned on and the start of operation is instructed (steps S103 and S203), the set operation times of the courses of both washing tubs are compared. For example, the set time of course a of the first washing tub is set to the second time. If it is shorter than the set time of course b of the washing tub (Yes in step S301), the operation start of the first washing tub is temporarily stopped (step S302) and the time is adjusted. On the other hand, since it is naturally determined No in step S401 on the second washing tub side, the process proceeds to step S204, and the operation is immediately started from the washing process.

  As the operation on the second washing tub side proceeds, the remaining operation time of course b decreases. On the first washing tub side, during the temporary stop, the decrease in the remaining operation time of the course b on the second washing tub side is continuously detected, and the remaining operation time of the course b is that of the first washing tub. When it becomes equal to the set time of the course a (step S303), the temporary stop is finished and the operation is started from the washing process (step S104). Thereafter, as in the first embodiment, the washing operation is performed up to steps S114 and S214, and the operation is terminated.

  In addition, when the setting time of the course b of the second washing tub is shorter than the setting time of the course a of the first washing tub (Yes in Step S401), the first washing tub and the second washing tub Since the operation is only the reverse of the above operation, the description is omitted.

  As described above, in the washing machine according to the third embodiment of the present invention, when the control units 1a and 1b arranged in the respective washing tubs instruct to start operation of two washing tubs simultaneously on different courses, either Setting a short driving time By automatically delaying the start time of the course, it is possible to maintain the performance of each course (cleaning, rinsing, dehydration) and to finish simultaneously while preventing fabric damage and increasing power consumption. In addition, the operability and convenience of customers can be improved in accordance with the effective use of time.

  Further, when left in the dehydrated state, there is a tendency that wrinkles and odors adhere to the laundry. However, after the dehydration is completed, the laundry can be taken out from the rotating drums 101 and 201 simultaneously and immediately. Therefore, the occurrence of these problems can be suppressed.

(Embodiment 4)
The configuration of the washing machine according to the fourth embodiment of the present invention is the same as that of the first embodiment.

  The point that the washing machine in the present embodiment is different from that in the first embodiment is that there is a difference in the set operation time of the course of washing, rinsing, and dehydrating in the first washing tub and the second washing tub. By performing immersion washing with less agitation and longer stop time in the washing process on the short side of the time difference and the set operation time, the operation end time is controlled to be the same between the first washing tub and the second washing tub. It is the point which constituted so as to.

  The control units 1a and 1b of the control means 112 set the process contents of the respective washing tubs using the operation units 4a and 4b and the display units 5a and 5b of the first and second washing tubs, When the start of operation is instructed, adjust so that the end of operation is at the same time by adding and extending immersion washing with less agitation and longer stop time in the washing course of the setting course with the shorter operation time.

  The operation flow during the washing operation of the control means of the washing machine in the present embodiment is as shown in FIGS. 9 and 10, starting with the washing process of the operation flow shown in FIGS. 5 and 6 (steps S104 and S204). During the determination of whether the predetermined washing time has elapsed (steps S105 and S205), an operation flow for performing immersion washing with less agitation and longer stop time in the washing process on the shorter set operation time side is inserted. .

  When the start button is turned on and the start of operation is instructed (steps S103 and S203), the washing process of both washing tubs is started (steps S104 and S204). Thereafter, the set operation times of the courses of the two washing tubs are compared. For example, when the setting time of the course a of the first washing tub is shorter than the setting time of the course b of the second washing tub (Yes in step S501) ), The first washing tub side starts immersion washing with a long stop time in a state where the laundry is less stirred and soaked in washing water (step S502). On the other hand, since it is naturally determined No in step S601 on the second washing tub side, the process proceeds to step S205, and a washing process is performed until a predetermined washing time elapses.

  As the washing process on the second washing tub side progresses, the remaining operation time of the course b decreases. On the first washing tub side, during the above-described immersion washing process, the decrease in the remaining operation time of the course b on the second washing tub side is continuously detected, and the remaining operation time of the course b is the first washing time. When it becomes equal to the set time of the course a of the tank (step S503), the immersion washing process is finished (step S504), and the process shifts to a normal washing operation. Thereafter, as in the first embodiment, the washing operation is performed up to steps S114 and S214, and the operation is terminated.

  In addition, when the setting time of the course b of the second washing tub is shorter than the setting time of the course a of the first washing tub (Yes in step S601), the first washing tub and the second washing tub Since the operation is only the reverse of the above operation, the description is omitted.

  As described above, in the washing machine according to the fourth embodiment of the present invention, when the control units 1a and 1b arranged in the respective washing tubs instruct to start operation of two washing tubs simultaneously on different courses, either By adding a predetermined immersion washing process to the washing process of the setting course with a short operation time and extending the time, it is possible to finish the course with a long operation time while improving the cleaning performance of the course with a short setting operation time. In addition to the cleaning performance, the operability and convenience for customers can be improved.

  Further, when left in the dehydrated state, there is a tendency that wrinkles and odors adhere to the laundry. However, after the dehydration is completed, the laundry can be taken out from the rotating drums 101 and 201 simultaneously and immediately. Therefore, the occurrence of these problems can be suppressed.

(Embodiment 5)
The configuration of the washing machine in the fifth embodiment of the present invention is the same as that in the first embodiment.

  The point that the washing machine in the present embodiment is different from that in the first embodiment is that there is a difference in the set operation time of the course of washing, rinsing, and dehydrating in the first washing tub and the second washing tub. By suspending the operation for a predetermined time after the final rinsing and stirring of the rinsing process on the short side of the time difference and the set operation time, and adjusting the final rinsing time, the operation end time is set to the first washing tub and the second washing time. It is the point comprised so that it might correspond with a tank.

  The control units 1a and 1b of the control means 112 set the process contents of the respective washing tubs using the operation units 4a and 4b and the display units 5a and 5b of the first and second washing tubs, When the start of operation is instructed, a predetermined stop time is provided after the final agitation of the final rinsing process of the course for which the shorter operation time is set, and adjustment is made so that the end of operation is at the same time.

(Embodiment 6)
The configuration of the washing machine in the sixth embodiment of the present invention is the same as that in the first embodiment.

  The washing machine in the present embodiment is obtained by adding a cloth unwinding process in which stirring is repeated intermittently for a predetermined time after the course operation of the washing machine in the first embodiment is completed.

  The operation flow during the washing operation of the control means of the washing machine in the present embodiment is a predetermined flow after the completion of the course operation shown in FIGS. 5 and 6 (steps S114 and S214), as shown in FIGS. The cloth unwinding process (steps S701 to S703, S801 to S803) in which stirring is repeated intermittently for a period of time is added. Detailed description is omitted.

  Although this cloth unraveling process is configured to be performed for a predetermined time, it is not so much related to the basic cleaning performance of washing away dirt, and thus ends when the user opens the lid 105, 205 during the process. (Steps S702 and S802).

  As described above, in the washing machine according to the fifth embodiment of the present invention, the control units 1a and 1b arranged in the respective washing tubs add a cloth unwinding process that repeats stirring intermittently for a predetermined time after the completion of each course operation. As a result, it is possible to further reduce the wrinkle of the laundry after dehydration that occurs between the end of dehydration and the time when the customer takes out the laundry. Further, by performing the cloth unraveling process after the dehydration is completed, there is no concern that the laundry is left on the inner periphery of the rotary drums 101 and 201 for a long time after the dehydration and the laundry is left unwrinkled. Therefore, it is not necessary to comprise so that a driving | operation may be complete | finished at the same time with a 1st washing tub and a 2nd washing tub like Embodiment 2-5.

  As described above, the washing machine according to the present invention can drive each of the first washing tub and the second washing tub in separate washing operation courses, and further, by operating the washing operation courses in substantially the same time. Since effective use of time and operability and convenience can be improved, it can be applied to other washing machines with a drying function.
