DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic washing machine provided with a detergent dispenser having a plurality of storage rooms capable of storing detergents and the like, and supplying water into a washing tub through the storage rooms.

[0002]

2. Description of the Related Art Conventionally, in a fully automatic washing machine, in addition to a standard course for washing ordinary laundry, a laundry with a high degree of soiling, or a stubborn soil with oil or chemicals penetrated. There is provided a so-called "stubborn dirt" course for washing laundry. In such a "stubborn dirt" course, it is set so that the execution time of the washing step is longer than in the standard course, and that the water flow is stronger.

[0003]

By the way, dirt of laundry put in water (hereinafter, washing liquid) mixed with detergent is dissolved in the washing liquid as the washing process proceeds. As much as the dirt on the laundry is removed, the washing liquid becomes dirty. When the washing liquid is contaminated to some extent, it is conceivable that the stain on the laundry is not eluted in the washing liquid. Therefore, even if the washing process is performed for a long time in the dirty washing liquid, not only the sufficient washing effect cannot be obtained, but also the dirt that has been dropped from the washing adheres to the washing again, and the washing action is rather performed. Was likely to decrease.

[0004] Therefore, it is conceivable to wash laundry with a high degree of soiling, for example, by repeating the standard course twice. However, in this case, when the first course is completed, it is necessary to press the start switch again or to supply the detergent again, which is troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fully automatic washing machine which can easily and reliably remove dirt even when washing heavy dirt.

[0006]

According to a first aspect of the present invention, there is provided a fully automatic washing machine including a washing tub, a detergent dispenser having a plurality of storage rooms capable of storing detergents, and the like, and the washing tub passing through the storage room. A water supply means for supplying water to the water supply means, and a control means for controlling the water supply means, wherein a multi-washing course for performing a washing step and a draining step a plurality of times is provided. Is selectively performed through the plurality of storage chambers.

[0007] According to the above configuration, when the detergent is stored in each storage room and the multi-washing course is executed, the washing process and the draining process are automatically performed a plurality of times, and the detergent is supplied when water is supplied in each washing process. Can be automatically input. In addition, since the washing liquid contaminated in the previous washing step can be discharged and the next washing step can be performed in the new washing liquid, the stain on the laundry can be surely removed.

In this case, if the rinsing step and the dewatering step are performed at least before the last washing step in the multiple washing course, it is possible to more reliably remove dirt from the laundry. Invention).

[0009] Further, there is provided a cloth amount detecting means for detecting the amount of the laundry stored in the washing tub, and at the time of execution of the over-washing course, the control means controls the amount of laundry based on the detection result of the cloth amount detecting means. Set the amount of water supply in the second washing
It is preferable that the water supply amount in the second and subsequent washing steps is set based on the water supply amount in the second washing step (the invention of claim 3).

[0010] According to the above configuration, the detecting operation by the cloth amount detecting means in the second and subsequent washing steps can be omitted, so that compared to the case where the detecting operation is performed in all the washing steps, the overlapping washing course is performed. Execution time can be shortened.

By the way, in the multiple washing course, laundry with a high degree of soiling is washed, so that the washing tub is more often stained at the end of the multiple washing course than at the end of the normal washing course. Therefore, it is preferable that, when the execution of the repetitive washing course is completed, it is configured to wait for the execution of the tub washing course for washing the washing tub (the invention of claim 4).

In this case, a water level detecting means for detecting a water level in the washing tub is provided, and the control means makes the water level in the washing tub in the tub washing course higher than the water level in the washing tub in the double washing course. If the water supply means is configured to perform a water supply operation, the dirt attached to the washing tub can be reliably removed (the invention of claim 5).

[0013] It is also good to provide a notifying means for notifying that the elapsed time from the end of the repetitive washing course has reached a predetermined set time (the invention of claim 6). According to such a configuration, for example, a user who forgets to take out the laundry from the washing tub despite the completion of the multiple washing course can be notified of the fact. In a configuration in which the tank cleaning course is waited for after the completion of the repeated washing course, the user can be prompted to execute the tank cleaning course.

[0014] Further, the detergent dispenser is configured to include a detergent storage chamber used for storing the detergent and a finish agent storage chamber used for storing the finish agent, and the execution of the above-mentioned multiple washing course is performed. In some cases, the detergent may be stored in both the detergent storage chamber and the finish storage chamber (the invention of claim 7). In order to automatically supply the detergent in all the washing steps of the multiple washing course, it is necessary to provide a plurality of detergent storage rooms, but according to the above configuration, to use the finishing agent storage room as a detergent storage room, There is no need to set up a special detergent storage room for multiple washing courses.

Specifically, a washing operation in which a water supply step, a washing step, a drainage step, a dehydration step, a water supply step, a rinsing step, a drainage step, and a dehydration step are sequentially performed is 2
It is executed repeatedly. Therefore, in this embodiment,
This "stubborn dirt" course corresponds to the repeated washing course.

At this time, as will be described in detail later, in the water supply process in the first washing operation, the first valve 19 of the double water supply valve 16 is opened to supply tap water. Also, in the water supply process in the second washing operation, the second valve 20 of the double water supply valve 16 is opened to supply tap water. Further, in this embodiment, when all the steps of the "stubborn dirt" course are completed, the "tank washing" course for washing the rotary tank 6 is automatically set to stand by.

Although a detailed description is omitted, the washing machine of this embodiment is automatically executed when the start switch is turned on without pressing the course selection key in addition to the "stubborn dirt course". In addition to the standard course, a “hand-washing” course, a “blanket washing” course, and the like, which are executed by selecting a course selection key and turning on a start switch, are provided. In these courses, the washing process is performed only once. Further, it is also possible to execute the “bath cleaning” course alone by pressing the course selection key. Further, in the washing machine of the present embodiment, when the “bath water supply” mode is selected on the operation panel 13, a predetermined water supply stroke is set to the water supply operation by the pump device 17.

Next, the operation of the above configuration will be described with reference to FIGS. The flowcharts of FIGS. 1 and 2 show the control circuit 3 when the “stubborn dirt” course is selected.
8 shows a processing procedure of the washing operation performed by the washing machine 8.
First, the operator operates the "stubborn dirt" course selection key on the operation panel 13 with the laundry stored in the rotating tub 6, and turns on the start switch.

Then, first, in step S1, an operation of detecting the weight of the laundry by the weight sensor 42 is performed, and the water level X (l) is set according to the detection result (step S1).
2). When the water level is set, the display unit 1 of the operation panel 13
3b, the detergent amount corresponding to the laundry amount (water level) is displayed (step S3). The operator looks at the display of the detergent amount and puts the unit container 25 of the detergent dispenser 15 into the water injection case 2.
In the state of being pulled out from the container 4, a predetermined amount of detergent is introduced into the detergent storage chamber 27 and the finish agent storage chamber 28, respectively.

Then, the unit container 25 is filled with the water injection case 2.
When it is detected that the sheet is accommodated in the washing machine 4, the first washing operation is started (step S4). That is, first, in step S5, the first valve 19 of the double water supply valve 16 is opened to start water supply. As a result, the tap water passes through the first passage 35 and further flows through the detergent storage chamber 27 into the rotary tank 6. At this time, since the detergent is stored in the detergent storage chamber 27, the detergent is supplied into the rotary tank 6 while being dissolved in tap water. That is, the detergent is automatically put into the rotary tank 6.

Tap water is supplied by the double water supply valve 16 until the water level in the rotary tank 6 reaches the set water level X (l). When the water level reaches the set water level (YE in step S6).
S), the water supply operation is terminated, and the remaining steps of the first washing operation, that is, the steps after the washing step are sequentially executed (step S7). The water supply operation before the rinsing step in the first washing operation is also performed by opening the first valve 19 of the double water supply valve 16 and until the set water level reaches X (l). At this time, since no detergent is stored in the detergent storage chamber 27, only tap water is supplied into the rotary tank 6.

When all the steps of the first washing operation have been completed (step S8), the second washing operation is started in step S9. That is, first, step S1
At 0, the second valve 20 of the double water supply valve 16 is opened and the water supply operation is started. As a result, the tap water passes through the second passage 36 and further passes through the finishing agent storage chamber 28 and the rotary tank 6.
Water is injected inside. At this time, since the detergent is stored in the finishing agent storage chamber 28, the detergent is automatically charged into the rotary tank 6.

The tap water is supplied by the double feed valve 16 until the water level in the rotary tank 6 reaches the set water level X (l). When the set water level is reached (step S1)
1 (YES), the water supply operation is terminated, and the remaining steps of the second washing operation are sequentially executed (step S12). In this case, the water supply operation before the rinsing stroke in the second washing operation is performed by opening the second valve 20 of the double water supply valve 16 and until the set water level reaches X (l). At this time, since the detergent is not stored in the finishing agent storage chamber 28, only the tap water is supplied into the rotary tank 6.

When all the steps of the second washing operation are completed (step S13), the buzzer 4 is turned on at step S14.
3 is sounded (for example, 1 second ON / 1 second OFF is repeated six times), the end of the “stubborn dirt” course is notified, and time counting is started. Step S15
The “bath cleaning” course is automatically set at
Is set to “0”.

When the operator notified of the end of the "stubborn dirt" course is to start the execution of the "tub washing" course, he takes out the laundry from the rotating tub 6 and turns on the start switch. Yes (YE in step S16)
S). Then, the process proceeds to step S17, and the “tank cleaning” course is started. That is, in step S18, the first valve 19 of the double water supply valve 16 is broadcast and water supply is started. In this water supply operation, the water level in the rotary tank 6 is (X + 5) l
Until the set water level is reached (step S
19 (YES), the water supply operation ends, and the remaining steps of the “tank cleaning” course are executed (steps S20 and S2).
1). In the “tank cleaning” course, a cleaning agent (bleach) for cleaning the tank is directly charged into the rotary tank 6.

Further, even if the start switch is not turned on immediately after the end of the "stubborn dirt" course (NO in step S16), the setting state of the "tank washing" course is continued for a predetermined time. That is, in step S21, it is determined whether or not a predetermined time, for example, 60 minutes, has elapsed from the end of the "stubborn dirt" course, and if the predetermined time has elapsed (YES), the value of N is increased by 1 in step S22. . If N is not 2 (NO in step S23), the buzzer 43 sounds again (step S23).
24).

After the second notification by the buzzer 43, if the operator turns on the start switch (YES in step S16), the "tank cleaning" course is started as described above. On the other hand, the second buzzer 43
If the start switch is not turned on by the operator even if the notification is given by (NO in step S16)
O), the setting of the “bath cleaning” course is canceled, that is, “bath cleaning”
The waiting state of the course ends.

According to the present embodiment, when the "stubborn dirt" course is executed, the washing step and the draining step are performed twice, and when the water is supplied before the first washing step and when the second washing step is performed. Detergent is automatically added at the time of previous water supply. Therefore, if the operator starts the "stubborn dirt" course and stores the detergent in the storage rooms 27 and 28, there is no need to operate anything in the course of the course, so that the operator is convenient. And
In this way, since the two washing steps can be performed in different washing liquids, it is possible to surely remove stains from the laundry.

In this embodiment, instead of performing the second washing step immediately after the first washing step and draining step, water supply, washing, draining, dehydrating, supplying water, rinsing, draining, and so on are not performed. The washing operation for sequentially performing each step of dehydration was repeated twice. Therefore, the dirt on the laundry can be more reliably removed.

Further, in the present embodiment, all the water supply of the "stubborn dirt" course is performed up to the water level set by detecting the weight of the laundry at the start of the first washing operation. Therefore, the weight detection operation of the laundry can be completed only once, and the execution time of the “stubborn dirt” course can be reduced.

Also, in this embodiment, "stubborn dirt"
When the course is executed, the rotating tank 6 is soiled, so that the "tank washing" course is automatically set when the "stubborn soiling" course is completed. Therefore, if it is desired to continue the tank cleaning after the “stubborn dirt” course is completed, the “tank cleaning” course can be started only by turning on the start switch, and the “tank cleaning” course is set again. This saves time and effort compared to the case.

When the “tank cleaning” course is followed by the “tank cleaning” course, the water level in the rotary tank 6 in the “tank cleaning” course is higher than the water level in the rotary tank 6 in the “stubborn dirt” course. The water level was set higher.
In particular, in the present embodiment, the water level in the "tank cleaning" course is set to be higher by 5 l than in the "stubborn dirt" course. Therefore, without using unnecessarily much water,
When the “stubborn dirt” course is executed, the rotating tub 6 that has become dirty can be reliably washed.

In the present embodiment, "stubborn dirt"
If the start switch is not turned on during a predetermined time from the end of the course, the buzzer 4
3 was made to ring. Therefore, the user can be encouraged to execute the “tank cleaning” course. In addition, when the worker forgets to take out the laundry from the rotating tub 6 even though the “stubborn dirt” course has been completed, this fact can be notified.

It should be noted that the present invention is not limited to the above-described embodiment, but may be modified as follows, for example. In the water supply in the second washing operation of the “stubborn dirt” course, both the first and second valves 19 and 20 are opened because the detergent in the detergent storage chamber 27 has already been charged into the rotary tank 6. You may go. With this configuration, the time required for water supply can be reduced by opening both the first and second valves 19 and 20 to supply water.

Once the washing operation has been performed, the laundry is in a state of containing water, so the second water supply operation of the “stubborn dirt” course (ie, the rinsing operation of the first washing operation) After (the previous water supply), it may be configured to be lower by a predetermined amount than the set water level. According to such a configuration, the amount of water used in the “stubborn dirt” course can be saved. Further, even before the second water supply process, it is possible to execute the laundry weight detection operation and set the water level based on the detection result.

It is also possible to omit the dehydration step and the rinsing step in the first washing operation of the "stubborn dirt" course. That is, the above-described series of steps may be performed only in the second washing operation. Even in such a configuration,
Since the second washing process is performed by replacing the dirty washing liquid with new washing liquid in the first washing process, compared to the conventional "stubborn dirt" course in which the washing process is performed for a long time in the same washing solution. To remove dirt from the laundry.

The present invention can be applied to a configuration in which the “tank cleaning” course is not automatically set even after the “stubborn dirt” course is completed. Further, in the “stubborn dirt” course, the washing process and the draining process may be performed three times or more. When the washing step and the draining step are performed three or more times, it is preferable that the rinsing and dewatering steps be performed at least before and after the final washing step. Further, the present invention can be applied to a washing machine provided with a detergent dispenser having three or more storage rooms.

The repeated washing course can be provided not only as a "stubborn dirt" course, but also as a washing course for the purpose of, for example, carefully removing dirt from laundry.

Further, the present invention is not limited to the washing machine in which the rotating tub and the stirring body are directly rotated by the motor, and the rotational force of the motor is transmitted to the rotating tub and the stirring body via the belt transmission mechanism. The present invention can be applied to a washing machine having a configuration.

[0052]

As is apparent from the above description, according to the fully automatic washing machine of the present invention, the washing step and the draining step are performed a plurality of times, and the water is supplied in the plurality of washing steps to the plurality of storages. Since a multi-layer washing course with a configuration that selectively passes through the chamber is provided, if the execution of this multi-layer washing course is started, the washing step and the draining step can be automatically performed a plurality of times,
Moreover, by storing the detergent in each of the storage rooms, the detergent can be automatically supplied at the time of supplying water in each washing process. Therefore, the dirt on the laundry can be surely removed and the usability can be improved.
