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 having operation control means for automatically executing and controlling a washing operation.

[0002]

2. Description of the Related Art In a fully automatic washing machine, for example, when a standard course is executed as a washing course, normal washing is well-washed by performing washing, rinsing and dehydrating operations in a standard washing operation pattern. It is configured to: The washing machine is configured to be able to execute a strong course when washing heavyly soiled laundry and a hand washing course when washing laundry made of a delicate material. Furthermore, when the user wants to perform washing according to his / her preference, it is possible to manually set washing conditions (water level, strength of water flow, operation time, etc.) by operating various switches. Have been.

[0003]

In general, the user often performs a standard course because the opportunity to wash ordinary laundry is the largest. In a fully automatic washing machine, a standard course is automatically set and executed unless an operation for selecting a course is performed. By the way, when the standard course is executed, the driving noise is considerably large. For this reason, when a user performs washing at night, the user is worried about the driving noise, and there is a demand for reducing the driving noise. Also, when you run a standard course,
It takes a long time to finish the washing operation. For this reason, there is a demand for shortening the time required for finishing the washing operation when it is desired to finish the washing and dry the washed laundry before going out in the morning.

[0004] On the other hand, a silent course for executing a washing operation pattern in which operation noise is reduced and a speed course for executing a washing operation pattern in which the time required until the end of the washing operation is shortened can be selected. Fully automatic washing machines are being considered. However, in this configuration, since an operation for manually selecting a quiet course or a speed course is required, the operation is troublesome. In addition, the manually selected course may not be the most suitable as a washing operation pattern to be executed from now on. Furthermore, when washing is performed at night, the user often sleeps after starting the washing operation, and in such a case, the laundry is left until morning in a state where the washing is completed until the final dehydrating operation. For this reason, many wrinkles are formed on the laundry, and color change may occur.

Therefore, an object of the present invention is to automatically select an optimum washing operation pattern as a washing operation pattern to be executed from now on, so that the usability can be greatly improved. It is an object of the present invention to provide a fully automatic washing machine capable of minimizing the occurrence of color shift.

[0006]

According to the present invention, there is provided a fully automatic washing machine comprising operation control means for automatically executing and controlling a washing operation, comprising: clock means for measuring a current time; The operation control means has a plurality of washing operation patterns according to time and automatically selects a washing operation pattern corresponding to the current time measured by the clock means from among the plurality of washing operation patterns. It is characterized in that it is configured to

According to the above arrangement, the washing operation pattern corresponding to the current time measured by the clock means is automatically selected from the plurality of washing operation patterns corresponding to the time. Thereby, a washing operation pattern that is optimal as a washing operation pattern to be executed from now on, that is, a washing operation pattern in which, for example, the operation noise is reduced as necessary, a washing operation pattern in which the time required to complete the washing operation is shortened, The washing can be executed in the washing operation pattern in which the final dehydration operation is not executed until morning. Therefore, the usability is greatly improved, and the occurrence of wrinkles and color fogging can be prevented as much as possible.

Further, in the case of the above configuration, it is preferable to provide a backup power source which retains the timekeeping function of the clock means when the power is turned off or when a power failure occurs. Further, it is a good configuration that each time corresponding to a plurality of washing operation patterns corresponding to the time can be changed. Furthermore, it is preferable that when the time of the clock means is not set, a standard washing operation pattern is automatically selected from a plurality of washing operation patterns.

On the other hand, it is more preferable that a desired one of a plurality of washing operation patterns corresponding to time can be manually selected. Further, in the washing operation pattern corresponding to night time, the rotation speed of the motor during the washing or dehydration operation is reduced below the standard, and
It is preferable that a temporary stop immediately before the final dehydration operation be performed. Further, in the washing operation pattern corresponding to nighttime, it is preferable that the final dehydration operation is automatically started at a predetermined time after a temporary stop immediately before the final dehydration operation. In this case, it is a good configuration to set the predetermined time as the morning start time.

Next, the operation of the above configuration will be described with reference to FIGS. The flowchart of FIG.
9 shows a schematic control content of control for automatically selecting a washing operation pattern corresponding to the current time in the control program stored in the control program 9. Here, in the present embodiment, for example, four washing operation patterns are prepared to be selectable as a plurality of washing operation patterns corresponding to time. These four washing operation patterns are configured to be automatically selected according to the current time when a standard course is executed as a washing course.

The above four washing operation patterns are a morning mode, a day mode, an evening mode, and a night mode. In this case, the morning mode is a pattern executed during the time period from “6:00” to “9:00”, and the day mode is “9: 0”.
This pattern is executed during the time period from “0” to “17:00”. In the evening mode, the pattern is executed from “17:00” to “22:00”.
The pattern is executed during a time period from “20:00” to “6:00”, and the night mode is a pattern executed during a time period from “22:00” to “6:00”. Hereinafter, the operation contents of these four modes (washing operation patterns) will be described with reference to FIG.

First, the morning mode will be described. In this mode, the speed driving is performed to reduce the time required for the washing operation. Specifically, the rotation speed of the motor 17 for the washing operation is increased (for example, 150 rpm) to shorten the execution time of the washing operation, and the rotation speed of the motor 17 for the initial dehydration operation for the rinsing process is increased (for example, 1000 rpm).
rpm), the execution time of the initial dehydration operation is shortened, and the rotation speed of the motor 17 in the rinsing operation is increased (for example, 150 rpm).
pm), the execution time of the rinsing operation is shortened, and the execution time of the final dehydration operation is shortened. This shortens the time required for the washing operation and shortens the execution time of the final dehydrating operation, so that wrinkles on the laundry can be reduced. As a result, the laundry can be easily taken out from the tub, and the laundry can be easily dried, and the post-washing process can be easily performed.

In the daytime mode, strong dehydration is performed in the final dehydration operation to reduce the amount of water contained in the laundry. Specifically, the rotation speed of the motor 17 in the final dehydration operation is increased (for example, 1000 rpm), and the execution time of the final dehydration operation is extended (for example, 4 minutes 30 minutes).
Seconds). As a result, the amount of moisture contained in the laundry decreases, so that even if the laundry is dried from noon, the laundry can be dried by the evening.

The evening mode is a combination of a morning mode and an evening mode. The speed mode is executed to reduce the time required for the washing operation. To reduce the amount of water contained. Specifically, the rotation speed of the motor 17 for the washing operation is increased (for example, 150 rpm) to shorten the execution time of the washing operation, and the rotation speed of the motor 17 for the initial dehydration operation for the rinsing process is increased (for example, 1000 rpm).
m) to shorten the execution time of the initial dehydration operation and increase the rotation speed of the motor 17 in the rinsing operation (for example, to 150 rpm).
m) to shorten the execution time of the rinsing operation, increase the rotation speed of the final dehydration operation (for example, 1000 rpm), and increase the execution time of the final dehydration operation (for example, 4 minutes 30 minutes).
Seconds). As a result, the time required for the washing operation can be reduced, and the amount of moisture contained in the laundry can be reduced. As a result, it is possible to satisfactorily cope with drying the laundry in the house or drying the laundry at night.

On the other hand, in the night mode, all the strokes are executed quietly, and the final dehydration operation is executed at the start time of the morning mode ("6:00"). Specifically, the rotation speed of the motor 17 for the washing operation is reduced (for example, 100 rpm), the execution time of the washing operation is lengthened, and the rotation speed of the motor 17 for the initial dehydration operation in the rinsing process is reduced (for example, 750 rpm). At the same time, the execution time of the initial dehydration operation is increased (for example, 6 minutes), and the rotation speed of the motor 17 for the rinsing operation is reduced (for example, 100 rpm).
And increase the execution time of the rinsing operation (for example, 3
Minutes), and after the rinsing operation, perform a weak dehydration operation (a dehydration operation in which the rotation speed is reduced (for example, 400 rpm) and the execution time is shortened (for example, 1 minute)) to temporarily stop (stand by), and thereafter, The final dehydration operation is executed at the start time of the morning mode ("6:00"). This final dehydration operation is the same operation as the final dehydration operation in the morning mode. That is, the rotation speed of the final dehydration operation is increased (for example, 1000 rpm), and the execution time of the final dehydration operation is set to, for example, 3 minutes.

Thus, the entire washing operation can be executed quietly. After the rinsing operation, the weak dehydration operation is performed to start the morning mode ("6: 0
0 "), and when the start time of the morning mode is reached, the final dehydration operation is executed, so that wrinkles on the laundry can be reduced and the color change of the laundry can be reduced. be able to.

Next, a process of automatically selecting one of the above four modes in accordance with the current time will be described with reference to FIG. In this case, first, in step S1 of FIG. 4, it is determined whether or not the standard course has been selected. When the switch for selecting the washing course is not operated, the standard course is automatically set.
Now, if the standard course is selected, step S
The process proceeds to "YES" at 1 to determine whether or not the count value of the clock counter is "00:00" (step S).
2). This determination is processing for determining whether or not the time of the clock has been set by the user.

Here, if the time is set,
Since the count value of the clock counter is not "00:00", the process proceeds to "NO" in step S2. Subsequently, it is determined whether or not the current time is before 6:00 AM, that is, before “6:00” based on the count value of the clock counter (step S3). In this case, if the current time is before “06:00” (that is, at night), the process proceeds to “YES” in step S3 to select and set the night mode, and thereafter, the start temporary stop switch 26 Is operated, the washing operation is executed in the night mode (step S4). When the night mode is selected and set,
The upper left LED 47 of the night switch 43 is configured to be turned on.

On the other hand, if the current time is after "06:00" in step S3, the process proceeds to "NO" to determine whether the current time is at 9:00 AM, that is, whether it is before "9:00". (Step S5). In this case, if the current time is before “9:00” (ie, in the morning),
The process proceeds to "YES" in step S5 to select and set the morning mode, and thereafter, when the start temporary stop switch 26 is operated, the washing operation is performed in the morning mode (step S6). When the morning mode is selected and set, the upper left LED 44 of the morning switch 40 is turned on.

If it is determined in step S5 that the current time is after "9:00", the process proceeds to "NO", and it is determined whether the current time is before 5:00 PM, that is, before "17:00". (Step S7). In this case, if the current time is before “17:00” (that is, if it is noon),
In step S7, the process proceeds to "YES" to select and set the daytime mode. Thereafter, when the start temporary stop switch 26 is operated, the washing operation is performed in the daytime mode (step S8). When the daytime mode is selected and set, the LED 45 at the upper left of the daytime switch 41 is turned on.

In step S7, if the current time is after "17:00", the process proceeds to "NO" to determine whether the current time is before 10:00 PM, that is, before "22:00". (Step S9). In this case, if the current time is before "22:00" (i.e., in the evening), the process proceeds to "YES" in step S9 to select and set the evening mode.
Is operated, the washing operation is executed in the evening mode (step S10). When the evening mode is selected and set, the upper left LED 46 of the evening switch 42 is turned on.

Further, in step S9, if the current time is after "22:00", the process proceeds to "NO". In this case, it is night, so the night mode is selected and set, and thereafter, when the start temporary stop switch 26 is operated, the washing operation is executed in the night mode (step S4).

On the other hand, if the count value of the clock counter is "00:00" in step S2,
Proceed to “YES”. In this case, since the time is not set and the current time is not known, for example, day mode is selected and set as a standard washing operation pattern. Thereafter, when the start / stop switch 26 is operated, the washing operation is performed in the day mode. (Step S
8).

If it is determined in step S1 that the standard course has not been selected, the process proceeds to "NO" to execute another selected course (step S11). In this case, specifically, as a course other than the standard course, a blanket course, a hand washing course, a dry course, or a tank washing course is executed. When each of these courses is selected, the upper left LED of a switch (operated course switch) corresponding to the selected course is turned on.

Further, even if the standard course is selected, if any one of the morning switch 40, the daytime switch 41, the evening switch 42 and the nighttime switch 43 is operated, regardless of the current time, The washing operation is performed in a mode corresponding to the operated switch. That is, a desired one of the four modes of the standard course can be manually selected. When each of the above modes is selected, the upper left LED of the switch (operated switch) corresponding to the selected mode is illuminated.

According to the present embodiment having such a configuration, the mode corresponding to the current time measured by the clock function of the control circuit 49 is automatically selected from the four modes (washing operation patterns) corresponding to the time. Since it is configured to select and execute the washing, it is possible to execute the washing to be executed from now on in an optimal washing operation pattern.

More specifically, in the morning, since the morning mode is automatically selected and executed, the time required for the washing operation can be reduced, wrinkles on the laundry can be reduced, and It becomes easy to take out the laundry, and it becomes easy to execute the processing after washing. In the daytime, the daytime mode is automatically selected and executed, so the amount of water contained in the laundry after washing is reduced, so even if the laundry is dried from noon,
The laundry can be dry by evening.

In the evening, the evening mode is automatically selected and executed, so that the time required for the washing operation can be shortened and the amount of moisture contained in the laundry after washing is reduced. Therefore, it is possible to sufficiently cope with drying laundry in a house or drying laundry at night. In the case of nighttime, the night mode is automatically selected and executed, so that all the steps of the washing operation can be executed quietly, wrinkles on the laundry can be reduced, and color change of the laundry can be reduced. it can. Moreover, in this case, the user only has to operate the start switch 26 to start the washing operation, and no special operation is required, so that the usability is greatly improved.

Further, in the above embodiment, four times corresponding to the time
Each time corresponding to one mode (washing operation pattern) can be changed. Specifically, the time change switch 36
By operating the time display sections 32 to 39,
The start time of each mode displayed in can be changed. Thereby, the four modes can be set as the washing operation patterns more corresponding to the life of the user, and the usability is further improved.

Further, in the above embodiment, the control unit 49
When the time of the clock function is not set, the day mode is automatically selected as a standard mode from the four modes (washing operation patterns). This allows
Even if the time is not set, the standard course in the daytime mode is executed, so that the washing operation can be executed without any trouble.

On the other hand, in the above embodiment, a desired one can be manually selected from four modes (a plurality of washing operation patterns corresponding to time). Specifically, the morning switch 40, the daytime switch 41, the evening switch 4
By operating either the switch 2 or the night switch 43, the washing operation is executed in a mode corresponding to the operated switch, regardless of the current time.
Thereby, the usability for the user is further improved.

Further, in the above-described embodiment, in the night mode, the rotation speed of the motor 17 during the washing or spin-drying operation is made lower than the standard, and the apparatus is stopped immediately before the final spin-drying operation and stands by. Thereby, wrinkles on the laundry can be reduced, and color change of the laundry can be reduced. In particular, in the present embodiment, since the weak dewatering operation is performed before the standby, the wrinkles can be reduced without leaving the laundry soaked in water.

In this embodiment, in the night mode, after a temporary stop immediately before the final dehydration operation, a predetermined time,
Specifically, the configuration is such that the final dehydration operation is automatically started when the morning start time comes. In the morning,
When the user takes out the laundry and tries to dry it, the washing operation is completely finished. Therefore, usability is further improved.
