BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic washing machine in which water other than tap water, such as bath water, can be supplied to a washing tub by a water absorption pump.

[0002]

2. Description of the Related Art A washing machine with a water absorption pump of this type is known, for example, from Japanese Patent Application Laid-Open No. 62-148694. There, as a laundry course, a bath water water supply course in which water other than tap water such as bath water (hereinafter simply referred to as bath water) is supplied by a water suction pump when water is supplied other than the final rinse,
The whole process is divided into a course where tap water is supplied, and any one of these courses can be arbitrarily selected.

Further, fully automatic so that it is possible to select whether to supply the bath water by the water absorption pump "only during washing" or "at the time of washing other than the final rinsing" by the following method. Washing machines are commercialized. FIG.
Shows an operation / display panel provided in the washing machine, in which a course switch 33, a bath water water supply start switch 32, and a tap water water supply start switch 31 are arranged side by side.

The course switch 33 allows selection of a bath water supply course and a course other than the bath water supply course. When the bath water supply course is selected by the course switch 33 and the start switch 32 for bath water supply is turned on to start washing, the bath water supply by the water suction pump is performed at the time of washing and rinsing other than the final rinsing. When a course other than the bath water supply course is selected by the course switch 33 and the start switch 32 for bath water supply is turned on to start washing, the bath water is supplied only during washing. Regardless of which course is selected by the course switch 33, when the tap water supply start switch 31 is turned on to start washing, tap water is supplied to all courses.

[0005]

However, in the above-mentioned conventional example, the selection of the bath water supply course or the tap water supply course by the water absorption pump is performed by a plurality of types of switch operations. Also, the bath water supply is "only when washing" or "when washing and rinsing other than final rinsing"
Which of the two is to be selected (hereinafter, simply referred to as the selection of the bath water supply step) is also made by operating a plurality of types of switches. For this reason, such a selection operation is troublesome, and there is a risk of erroneous operation. In addition, since there is no means for displaying or notifying the selection of the bath water supply process, the user cannot confirm the correctness after the selection, and the user will not know the selection error until he / she operates it. However, there was a handling disadvantage and inconvenience of re-selecting.

The present invention has been made in view of the above problems, and it is possible to improve the operability of the presence / absence setting of the bath water supply course and the selection setting of the bath water supply process and prevent erroneous operations. The purpose is to provide a fully automatic washing machine. Another object of the present invention is to provide a fully-automatic washing machine capable of facilitating confirmation of selection of a bath water supply process.

[0007]

[Means for Solving the Problems] According to the present invention, the user can use one switch to "supply the bath water for washing only", "supply the bath water for rinsing other than washing and final rinsing", and "supply the tap water for all steps". The configuration is such that the three settings can be set arbitrarily. For that purpose, whether or not there is a bath water supply course that supplies water other than tap water such as bath water to the aquarium with a water supply pump,
Select whether or not the bath water is supplied "only when washing" or "when washing and rinsing other than final rinsing".
It is provided with operating means that can be operated by one bath water switch, and display means for displaying the operation progress state and the presence / absence of setting of the bath water supply course.

The present invention further uses existing display means to notify the user of the selected states of "flush water supply only during washing" and "flush water supply during washing and rinsing other than final rinsing". A means for displaying using a certain driving progress display is provided.

According to the present invention, any one of the above three settings is selected, and a storage means for storing the setting is provided even after a series of washing steps is completed, and the stored setting is automatically set at the next setting. The configuration selected in.

According to the present invention, a normal driving progress display blinks and
In order to inform the user of the difference between the above-mentioned "brush water supply only during washing" and "blinking of progress water display by" bath water supply during washing and rinsing other than final rinsing ", the blinking cycle of both is different. I shall.

[0011]

[Operation] With the above operating means, the user can freely set the presence or absence of the setting of the bath water supply course and the selection of the bath water supply process with one bath water switch, and the user can use the bath water supply course. Very easy for

By using the operation progress display which is an existing display means, it is used to determine whether the setting state of "flush water supply only when washing" or "flush water supply when washing and rinsing other than final rinsing" is set. Can be clearly displayed to the person.

Of the three settings, "Flush water supply only when washing", "Frost water supply when washing and rinsing other than final rinsing", and "All process tap water supply", the last used setting is stored. Since it is stored and selected in the initial state at the time of the next setting, the user can save the trouble of switching to the setting that is always used each time it is used.

By having different blinking cycles, it is clarified that the display means of "Flush water supply only during washing" and "Flush water supply during washing and rinsing other than final rinsing" is not a progress indicator of normal operation. The user can be informed.

Next, a method of setting the bath water supply course will be described. Here, the bath water water supply course normally supplies water to the inside of the water tank 10 by supplying tap water by ON-OF of the water supply valve 2. However, when the bath water water supply course is selected, water supply to the water tank 10 is performed. Is the water suction pump 12 ON-O
By F, water other than tap water such as bath water is automatically supplied. Therefore, the user does not have to perform the ON-OF of the water absorption pump 12 by himself, and all can automatically wash the water by using the water other than tap water such as bath water to the maximum. is there.

When the power switch 21 is off, all of the display devices are off. When the power switch 21 is turned on, the display state as shown in FIG. 4 is obtained. At this time, when the course switch 23 is turned on, the course display 38 is sequentially "standard" → "careful" → "washing" → "blanket" →
It switches to "wool" (in the example of Fig. 4, "standard" is displayed). When the washing switch 26 is turned on, the washing time display 30a is switched, and an arbitrary washing time can be selected (in the example of FIG. 4, "10 minutes" is displayed).

When the rinsing switch 25 is turned on, the rinsing number display 30b is switched, and the rinsing number can be arbitrarily selected (in the example of FIG. 4, "1" is displayed). When the dehydration switch 24 is turned on, the dehydration time display 30c is switched, and an arbitrary dehydration time can be selected (“6 minutes” is displayed in the example of FIG. 4).

The reservation switch 27 is used for setting reserved operation. When the water level switch 29 is turned on, the water level display 36 is sequentially switched to "high", "medium", "low", and "small amount", and any one of the water levels can be arbitrarily selected (in the example of FIG. 4, " Display a small amount "). Bath water switch 28
Is used to set the bath water supply course. Washing time display 30a, rinse number display 30b, and dehydration time display 30
The driving progress display 30 of c notifies the user of the current driving state by blinking the process currently being executed during driving.

When setting the bath water supply course, the power switch 21 is first turned on. At this time, as a default setting, the bath water display 20 is turned off and the bath water supply course is not set (state of FIG. 4). Next, when the bath water switch 28 is turned on, the bath water display 20 is turned on, and the washing time display 30a of the operation progress display 30 is displayed.
Blinks in a cycle different from that of the progress display during operation (state of FIG. 5).

Next, when the bath water switch 28 is turned on again, the bath water display 20 remains lit, and the washing time display 30a and the rinsing frequency display 30b of the progress display 30 indicate the progress display during operation. Flashes in a cycle different from the flashing cycle (state of FIG. 6). Next, when the bath water switch 28 is turned on again, the bath water display 20 is turned off, the operation progress display 30 is turned on, and the bath water supply course is not set (state of FIG. 4).

When the operation is started by the start / pause switch 22 from each of the above set states, the water supply valve 2 is used to supply water for all processes from the set state without the bath water supply course (FIG. 4). I can wash it. Illumination of bath water display 20 and washing time display 30
From the blinking state of a (FIG. 5), the water supply in the washing process is performed by the bath water supply by the water absorption pump 12, and the water supply in the rinsing process is performed by tap water supply by the water supply valve 2.

The operation progress display 30 after the operation is started is a display showing the progress of each step as usual. Regarding the blinking cycle indicating the driving progress state at this time and the blinking cycle at the time of setting the bath water supply course, specifically, for example, 0.5 ″ ON / 0.5 ″ OF during normal driving progress display Then, the blinking cycle when the bath water supply course is set is 0.5 "ON /
0.2 ″ OF.

Illumination of the bath water display 20 and washing time display 30
From the blinking state of "a" and the number of times of rinsing 30b display (Fig. 6), water supply at the time of washing and rinsing other than the final rinsing is performed by bath water supply by the water absorption pump 12, and water at the final rinsing is tap water by the water supply valve 2. It is done by water supply. The operation progress display 30 after the operation is started is a display showing the progress of each process as usual. When a series of washing operations as set for each is completed, the power is automatically turned off.

The setting state of the bath water supply course set as described above is stored in the storage unit 35 of the microcomputer 19. Therefore, when the power switch 21 is turned on next time to turn on the power again, at this time, the above setting state, that is, the setting state of the bath water supply course set at the time of the previous setting is displayed as the initial setting. Of course, if the vehicle is started as it is, the operation can be performed with the same setting as the previous time, and if the setting is switched by the bath water switch 28, the operation can be performed with an arbitrary setting (see the flowchart of FIG. 7).

As described above, according to the above embodiment, it is possible to set the presence / absence of the bath water supply course and to selectively set the bath water supply process with one bath water switch 28. Although the display device has been described as a fluorescent display tube in the above-described embodiments, it may be an LED or a liquid crystal display device generally used as a display element.

[0032]

As described above, according to the present invention, the user can freely set the presence / absence of the bath water supply course and the selection setting of the bath water supply process with one bath water switch. The use of the bath water supply course becomes very easy for the user, and the bath water can be effectively used to improve the water saving effect.

Since the state of selection of the bath water supply process can be clearly displayed to the user by using the operation progress display which is an existing display means, the user does not have to be familiar with the operation method. It is convenient because it is easy to select the bath water supply process. Further, since the existing display is used, the cost of the display device such as the display element can be reduced.

Since the setting of the presence / absence of the bath water supply course and the setting contents of the selection of the bath water supply process are stored in the storage means and this is the initial state at the next setting, the user is required to use each time. , You don't have to switch to the settings that you always use, and the usability is great.

Since the display blinking cycle of the normal operation progress display and the display blinking cycle of the progress display in the selected state of the bath water supply process are different, it is possible to clearly inform the user of the difference between the two. Therefore, it is possible to prevent misperception and misunderstanding in the operation of the user.
