Description

  Embodiments of the present invention relate to a fully automatic washing machine.

  Conventionally, in a fully automatic washing machine, a rotating tub is arranged in a water tub, and an agitator is arranged in the rotating tub. By rotating the agitator during washing operation, washing and rinsing are performed, and rotation is performed. The tank is rotated so that dehydration is performed, and a finishing agent such as a softening agent is sequentially transferred from room to room as the washing operation progresses, and finally finished in the water tank. The one provided with the agent feeder.

  In this case, the transfer of the finishing agent is specifically based on the transfer due to the centrifugal force of the rotation of the rotating tub in the dehydration of the washing operation. Therefore, the finishing agent is transferred by the number of times of the dehydration, and the final rinse is performed. It is designed to be put in the water tank before. For example, when two washing operations are selected, the control device for controlling the washing operation is configured to perform washing, dehydration, first rinse, dehydration, second rinse, and dehydration in that order. Accordingly, the finishing agent is put into the water tank from the finishing agent feeder by the second dehydration before the second rinse which is the final rinse.

JP 07-031783 A

  In the washing operation, there is a course or manual for performing three times of rinsing, and when this is selected, the finishing agent is thrown into the water tank from the finishing agent feeder during dehydration between the first rinse and the second rinse. As a result, there arises a problem that the effect of the finishing agent cannot be obtained at the time of the third rinse, which is the final rinse.

  Therefore, recently, when three washing operations are selected, the control device omits the dehydration between the first rinse and the second rinse, and dewaters before the third rinse that is the final rinse. Sometimes, the finishing agent is put into the water tank from the finishing agent feeder. However, when this is done, the dehydration between the first rinse and the second rinse is eliminated, so that there is no interruption period in which the continuous stirring of the laundry in the washing water for a long time is interrupted. As a result, the first rinse and the second rinse of the two washing operations are continuously performed, and the laundry is continuously stirred in the washing water. The degree of entanglement increases, and an unbalanced state is likely to occur, and the possibility that the rotating tank will generate abnormal vibration during the next dehydration increases.

  Thus, a fully automatic washing machine is provided that can reduce the degree of entanglement of the laundry during rinsing and suppress the occurrence of an unbalanced state as much as possible when the washing operation is performed three or more times.

  The fully automatic washing machine of the present embodiment includes a water tank elastically supported in an outer box, a rotary tank that is rotatably arranged in the water tank and is driven to rotate during dehydration, and a rotary tank that is rotationally driven during dehydration. A stirring body that is rotationally driven at the time of rinsing, and a plurality of chambers that are attached to the rotating tub and sequentially transfer the finishing agent to each dehydration by the rotating tub accompanying the progress of the washing operation and finally put into the water tub And a control means for controlling a washing operation including washing by the stirrer, rinsing, and dewatering by a rotating tub. When the washing operation is selected twice, the control means executes washing, dewatering, first rinsing, dewatering and second rinsing, and finishes from the finishing agent feeder by two dehydrations. When the washing operation is selected three times or more, the dehydration between the first rinse and the second rinse is omitted, and the execution time of the first rinse and the second rinse is set. Each is characterized in that it is set to be shorter than the execution time of the first rinse in the two washing operations.

(First embodiment)
The first embodiment will be described below with reference to FIGS. 1 to 6.
First, FIG. 2 shows an outer case 1 of a fully automatic washing machine, in which a water tank 2 is elastically supported by a suspension mechanism 4 mainly composed of a plurality of suspension rods 3 (only one is shown). Yes. In the water tank 2, a rotating tank 6 having a large number of dewatering holes 5 on the circumferential side is arranged, and in the rotating tank 6, a stirring body 7 is arranged at the bottom. Further, a finishing agent dispenser 8 is detachably attached to the upper part of the peripheral side surface in the rotary tank 6.

  As shown in FIGS. 3 and 4, the finishing agent feeder 8 has a second chamber 10 in the upper rear portion of the first chamber 9, and is located in front of the second chamber 10 and the first chamber 10. A third chamber 11 is provided on the side of the chamber 9, and a finishing agent inlet 13 facing the inside of the first chamber 9 is formed in a lid 12 common to them. The first chamber 9 communicates with the second chamber 10 through a communication port 14 formed in the upper portion of the back wall of the first chamber 9, and the second chamber 10 communicates with the third chamber 11. It communicates with a communication passage 15 formed from the bottom surface of the second chamber 10 to the inside of the third chamber 11, and further from the third chamber 11 to the outside of the finishing agent feeder 8 (inside the water tank 2, and hence in the rotating tank 6). The top faces the discharge port 16 formed in the upper part of the back wall of the third chamber 11.

  In the lower part outside the water tank 2, a drive mechanism 18 mainly composed of a motor 17 made of a condenser motor is disposed. By this drive mechanism 18, the rotary tank 6 is restrained and agitated during washing and rinsing. The body 7 is rotated forward and backward, and the rotating tub 6 is rotated in one direction together with the stirring body 7 during dehydration. In addition, the motor 17 is provided with a rotation sensor 19 that includes, for example, a magnet that rotates together with a rotation shaft and a corresponding hall element (none of which is shown), and detects the rotation of the motor 17. Yes. Further, a drain valve 20 and a drain hose 21 for draining from the inside of the water tank 2 (inside the rotary tank 6) are disposed in the lower part outside the water tank 2.

  On the other hand, a top cover 22 is mounted on the outer box 1. A water supply valve 23 for supplying water into the rotating tank 6 and an inside of the water tank 2 (inside the rotating tank 6) are disposed at the rear inner side of the top cover 22. And a water level sensor 24 for detecting the water level of the water tank, and an abnormal vibration detection switch 26 which is an abnormal vibration detecting means for detecting abnormally large vibrations of the rotating tank 6 by the contact of the water tank 2 with the detection lever 25. It is arranged. When the abnormal vibration detection switch 26 performs the detection operation, the washing operation (dehydration) is stopped as is well known.

  A control device 27 is disposed inside the front portion of the top cover 22. The control device 27 is mainly composed of a microcomputer and functions as a control means. As shown in FIG. 5, various operation signals are input from a switch input unit 28 including various operation switches, and A water level detection signal is input from the water level sensor 24, an abnormal vibration detection signal is input from the abnormal vibration detection switch 26, and a rotation detection signal is input from the rotation sensor 19. The control device 27 counts the rotation speed of the motor 17 from the rotation detection signal input from the rotation sensor 19 and divides it by the reduction ratio of the drive mechanism 18 and the required time to detect the rotation speed of the rotating tub 6. Therefore, the rotation sensor 19 functions as a rotation speed detecting means for detecting the rotation speed of the rotating tub 6.

  Accordingly, the control device 27 is a display unit 29 composed of various displays, an end notification device, and an abnormality notification based on those inputs and a control program selected from a plurality of control programs stored in advance. A drive control signal is given to a drive circuit 31 for driving the buzzer 30, the water supply valve 23, the motor 17, and the drain valve 20, which is also a container, so that the washing operation selected from a plurality of washing operations is controlled. It has become.

Next, the operation of the first embodiment will be described with reference to FIGS.
First, the case where the two washing operations are selected by the course or the manual will be described with reference to FIG.
When the operation starts, the control device 27 executes normal [washing] for a predetermined time, although not shown in the drawing. In this [washing], the finishing agent 32 placed and set in the first chamber 9 from the finishing agent inlet 13 of the finishing agent feeder 8 as shown in FIG. 6A remains in the first chamber 9. ing.

  Next, in the first “dehydration 1”, the finishing agent 32 is secondly passed from the first chamber 9 through the communication port 14 by the centrifugal force generated by the rotation of the rotating tank 6 as shown in FIG. To the chamber 10. This “dehydration 1” is performed for “4 minutes and 30 seconds” (in the figure, shown as “4′30 ″”, the same applies hereinafter). During this “dehydration 1”, the finish 32 remains in the second chamber 10.

  Next, in the “reservoir 1 (first rinse)”, the finishing agent 32 is transferred from the second chamber 10 to the third chamber 11 through the communication passage 15 as shown in FIG. And stays in the third chamber 11 during the “rinse 1”. In this “rinse rinse 1”, “water supply” is performed by the water supply valve 23, and when the water level in the water tank 2 reaches the set water level and this is detected by the water level sensor 24, “water supply” is stopped, and the stirring body 7 “Preliminary stirring” by rotation of “1 min 00 sec” is performed. This “preliminary stirring” is carried out with a short period of water flow. Next, “main stirring” by water flow in a normal cycle is performed for “2 minutes 30 seconds”. In the above-mentioned “preliminary stirring”, stirring is performed with a water stream having a shorter cycle than “main stirring” before “main stirring”. In addition, the “stirring stirring” by the short-cycle water flow is performed for “30 seconds”, and then “drainage” by the drain valve 20 is performed. This “drainage” is continued for “70 seconds” after the washing water in the water tank 2 by the drain valve 20 is discharged and becomes lower than the minimum detection water level of the water level sensor 24 and the water level sensor is reset.

  That is, in “Rinse 1”, “preliminary stirring”, “main stirring”, and “relaxation stirring”, which are a plurality of stirring modes, are executed, and the total stirring time is “4 minutes 00 seconds”. In this case, “preliminary agitation” is agitation for peeling the laundry pressed against the inner wall of the rotating tub 6 and “main agitation” is agitation for obtaining a strong detergency. Agitation] is an agitation that loosens the intertwined laundry.

  Next, in the second “dehydration 2”, the finishing agent 32 is a centrifugal force generated by the rotation of the rotary tank 6 and the finishing agent feeder is passed through the discharge port 16 from the third chamber 11 as shown in FIG. 8 is discharged outside and put into the water tank 2. “Dehydration 2” is set to “4 minutes 30 seconds” in the same manner as “Dehydration 1”. During this “dehydration 2”, the finishing agent 32 remains on the inner peripheral surface portion of the water tank 2.

Further, in the “final rinsing (second rinsing)”, the finishing agent 32 reaches the lower part in the water tank 2 by natural flow. In the “final rinsing”, first, “water supply” is performed, and the finishing agent 32 enters the rotary tub 2 through the dewatering holes 5 together with the supplied washing water. In the “final rinsing”, “preliminary stirring”, “main stirring”, and “unraveling stirring” are performed for the same time in the same manner as “irrigation 1” (the total stirring time is “4 minutes 00 seconds”). After that, “drainage” is performed in the same manner. Accordingly, the finishing agent 32 is effective in this “final rinse”.
The control device 27 executes “final dehydration” for “8:00 minutes”, which is a predetermined time, and “washing”, “dehydration 1”, “reserve rinse 1 (first rinse)”, “dehydration 2”. , Two washing operations including “final rinsing (second rinsing)” and “final dewatering” are executed, and the process ends.

Next, a case where three washing operations are selected by a course or a manual will be described with reference to FIG.
When the operation is started, the control device 27 first executes normal [washing] for a predetermined time in the same manner as the above-described two washing operations. In this [washing], the finishing agent 32 placed and set in the first chamber 9 from the finishing agent inlet 13 of the finishing agent feeder 8 as shown in FIG. 6A remains in the first chamber 9. ing.

  Next, in the first “dehydration 1”, the finishing agent 32 is secondly passed from the first chamber 9 through the communication port 14 by the centrifugal force generated by the rotation of the rotating tank 6 as shown in FIG. To the chamber 10. This “dehydration 1” is performed for “3 minutes 30 seconds”. That is, the execution time of “dehydration 1” in the three washing operations is set shorter than the execution time of “dehydration 1” in the two washing operations described above. During this “dehydration 1”, the finish 32 remains in the second chamber 10.

  Next, in the “reservoir 1 (first rinse)”, the finishing agent 32 is transferred from the second chamber 10 to the third chamber 11 through the communication passage 15 as shown in FIG. And stays in the third chamber 11 during the “rinse 1”. In “Rinsing 1”, “water supply” is performed by the water supply valve 23, and when the water level in the water tank 2 reaches a predetermined water level (lower than the set water level) and the water level sensor 24 detects this, the stirrer 7 It is rotated and “feed water agitation” is performed. Thereafter, when the water level in the water tank 2 reaches the set water level and the water level sensor 24 detects this, the water supply by the water supply valve 23 is stopped, and the “water supply agitation” ends. This “feed water agitation” is for peeling off the laundry containing the detergent pressed against the inner wall of the rotating tub 6 in the “dehydration 1” in the previous stage or for facilitating peeling.

  In “Rinse rinse 1”, “preliminary agitation”, “main agitation”, “relaxation agitation”, and “drainage” are sequentially performed in the same manner as “Rinse rinse 1” in the two washing operations. “Preliminary stirring” is set to “1 minute 00 seconds”, “Main stirring” is set to “45 seconds”, and “Unraveling stirring” is set to “30 seconds”. That is, the total stirring time of “preliminary stirring”, “main stirring”, and “unwinding stirring” of “Train Rinse 1” in the three washing operations is “2 minutes 15 seconds”, and the washing operation is performed twice. The total stirring time of “preliminary stirring”, “main stirring”, and “loosening stirring” of “Rinse rinse 1” is set shorter than “4 minutes 00 seconds”.

  Next to “Take Rinse 1”, “Take Rinse 2 (Second Rinse)” is executed. In other words, in this three-rinsing washing operation, unlike the two-rinsing washing operation, the “dehydration 2” after the “rinse 1” is omitted and not executed. In this “rinse rinse 2”, “feed water stirring” next to “water supply” is not performed, and when the water level in the water tank 2 reaches the set water level, “main stirring” is performed. "Draining" is performed sequentially. In this “rinse rinse 2”, “preliminary stirring” (time “0 second”) is not performed in addition to “feed water stirring”. This is because there is no “dehydration 2” between “spin rinse 1” and “spin rinse 2”.

  In this case, in “Rinse rinse 2”, “Preliminary stirring” is “0 second”, “Main stirring” is “1 minute 45 seconds”, “Unraveling stirring” is “30 seconds”, and the total stirring time is “2 minutes” “15 seconds” is set to be shorter than the total stirring time “4 minutes 00 seconds” of “reservoir 1” in the two washing operations. The total stirring time (“2 minutes 15 seconds”) of “preliminary stirring”, “main stirring”, and “relaxing stirring” of “rinse rinse 2” is “preliminary stirring”, “main Same as the total stirring time (“2 minutes 15 seconds”) of “stirring” and “relaxing stirring”, but the time distribution of “preliminary stirring”, “main stirring”, and “relaxing stirring” as multiple stirring modes is different. .

  After “Take Rinse 2”, the second “Dehydration 2” is performed. In this “dehydration 2”, the finishing agent 32 is discharged out of the finishing agent feeder 8 from the third chamber 11 through the discharge port 16 as shown in FIG. Then, it is put into the water tank 2. This “dehydration 2” is set to “3 minutes and 30 seconds” in the same manner as “dehydration 1”. During this “dehydration 2”, the finishing agent 32 stays on the inner peripheral surface portion of the water tank 2.

  Further, in the “final rinsing (third rinsing)”, the finishing agent 32 reaches the lower part in the water tank 2 by natural flow. In the “final rinsing”, first, “water supply” is performed, and the finishing agent 32 enters the rotary tub 2 through the dewatering holes 5 together with the supplied washing water. In the “final rinsing”, “preliminary stirring”, “main stirring”, and “relaxation stirring” are performed for the same time in the same manner as the “final rinsing (second rinsing)” in the two washing operations. (Total stirring time is “4 minutes 00 seconds”), and then “drainage” is performed in the same manner. The finishing agent 32 is effective in this “final rinse”.

  The control device 27 executes “final dehydration” for “8:00 minutes”, which is a predetermined time, and “washing”, “dehydration 1”, “reserve rinse 1 (first rinse)”, “refresh rinse 2”. The washing operation is performed three times including (second rinsing), “dehydration 2”, “final rinsing (third rinsing)” and “final dehydration”, and the process ends.

  Thus, according to the first embodiment, in the washing operation of three rinses, “dehydration 2” between “spin rinse 1” and “spin rinse 2” is omitted, and “dehydration 2” ”Is executed between“ Rinse rinse 2 ”and“ Final rinse (third rinse) ”, so that the finishing agent 32 of the finishing agent feeder 8 is placed in the water tank 2 at the“ final rinse ”. The finishing agent 32 can be sufficiently exerted in the “final rinse”.

  In addition, the execution stirring time of each of “washing rinse 1” and “washing rinse 2” of the three washing operations is set shorter than that of “washing rinse 1” of the two washing operations. As a result, the time during which the laundry is agitated in the washing water is shortened, and the degree of entanglement of the laundry can be reduced. Therefore, the occurrence of an unbalanced state of the laundry can be suppressed as much as possible. It is possible to prevent the washing operation from being stopped due to the abnormal vibration detection switch 26 operating due to the abnormal vibration of the rotating tub 6 during the “dehydration”. In this case, the total effective stirring time (“4 minutes and 30 seconds”) of “Rinse rinse 1” and “Torrow rinse 2” is equal to the effective stirring time of “Rinse rinse 1” in the two washing operations (“4 minutes”). 00 seconds "), the rinse effect is sufficiently obtained.

  Furthermore, in the three washing operations, the time distribution of “preliminary stirring”, “main stirring”, and “unwinding stirring” as a plurality of stirring modes is different between “rinsing rinse 1” and “spinning rinse 2”. Since it is set, optimal rinsing can be performed depending on whether or not “dehydration” is performed in the previous stage.

  In addition, in “dehydration 1”, the laundry containing the detergent easily comes into pressure contact with the inner wall of the rotating tub 6, but in the first embodiment, “feed water agitation” is performed in “reservoir rinse 1”. Therefore, the laundry can be peeled off from the inner wall of the rotating tub 6 or can be easily peeled off.

  The execution time of “dehydration 1” and “dehydration 2” in the three washing operations is set shorter than the execution time of “dehydration 1” and “dehydration 2” in the two washing operations. The time required as a whole is not so different from the time required for two washing operations, and an increase in power consumption can be suppressed.

(Second Embodiment)
Next, the second embodiment will be described with reference to FIG. 7. For convenience of description, FIG. 2 and FIG. 5 are also referred to.
FIG. 7 shows “dehydration” of three washing operations when the water level (the amount of laundry as a load amount) provided in the water tank 2 is set according to “high”, “medium”, and “low”. The specifications of “1”, “Rinse 1”, “Rinse 2”, “Dehydration 2”, “Final Rinse” and “Final Dehydration” are shown.
