Here, the setting items are "course",
There are four items: "detergent", "water level", and "manual".
The content of the "course" includes four washing courses of "putting on", "large items", "hand washing", and "standard", and the content of the "detergent" is "powder",
There are three types of "standard" and "concentrated", and "water level" has four water levels of "small amount", "low", "medium", and "high",
The "manual" has three operations: "wash", "rinse", and "dehydration".

The four courses included in the setting item "Course" are for automatically executing a series of washing steps from the washing step to the dehydration step in accordance with a predetermined program. Suitable for washing heavily soiled laundry, with a step of immersing the laundry in the washing water for a specified time before the washing process, "Large items" course is a "hand wash" course when washing large items such as blankets The "standard" course is suitable for washing wool laundry such as sweater, and the "standard" course is suitable for washing ordinary laundry. Of these, the "standard" course is generally and most often used.

The rotary shaft 15a of the rotary encoder 15 penetrates the operation panel 12 and projects to the upper surface thereof, and the dial 1 as a knob is provided at the upper end of the projection.
6 is attached. And the rotary encoder 15
When the dial 16 is operated to rotate, it outputs the A-phase pulse PA and the B-phase pulse Pb as shown in FIG. 4, and the outputs are given to the microcomputer 13.

Here, A-phase pulse PA and B-phase pulse P
b is 90 degrees out of phase, and when the dial 16 is rotated in the positive direction indicated by the arrow A in FIG. 1, the B phase output is at the high level (H) (while the B phase pulse Pb is being output). , The A phase output changes from the high level to the low level (L) (disappearance of the A phase pulse PA), and when the dial 16 is rotated in the opposite direction to the arrow A, the B phase output becomes the low level. (While the B-phase pulse Pb is not being output), the A-phase output changes from the high level to the low level. Then, the microcomputer 13 is configured to detect whether the dial 16 is rotated in the forward or reverse direction based on the output states of both the A and B phases.

Further, the rotary shaft 1 of the rotary encoder 15
As shown in FIG. 3, a gear 17 having a plurality of teeth 17a on the outer periphery is attached to the 5a as a moderating rotary body having a plurality of protrusions on the outer periphery, and is provided on the back side of the operation panel 12.

When 7 rotates integrally with the rotating shaft 15a, the leaf springs 18 elastically deform and pass over the teeth 17a one by one.
A sense of moderation is given to the fingers that rotate the dial 16. Therefore, the gear 17 and the leaf spring 18 function as a detent mechanism 19. In the case of this embodiment, the leaf spring 18
Emits a click sound "click, click" every time it comes off one tooth 17a and hits the next tooth 17a.

Inside the rotary encoder 15,
For example, an item selection switch 20 including a tact switch
(See FIG. 5) is provided, and the push button 21 of the item selection switch 20 is inserted through the central portion of the dial 16 and protrudes from the upper surface of the dial 16. The ON signal of the item selecting switch 20 is the microcomputer 1
It is given to three.

On the other hand, the operation panel 12 is provided with a display section 22 as shown in FIG. 1, and the display section 22 has "course", "detergent", and "setting items" as setting items necessary for washing operation. The four levels of "water level" and "manual" are displayed in a positional relationship of left and right front and back (left and right top and bottom in FIG. 1).
Of these, the contents of the "course" display portion 22a are "standard", "hand wash", "large items", from the right in order.
The four courses of "putting on" are displayed in letters, and the three kinds of "concentrate", "standard", and "powder" are displayed on the "detergent" display portion 22b in order from the right as "water level". In 22c, the content is "high" in order from the right.
"Medium", "Low", "Small" 4 water levels are "Manual"
In the display portion 22d of, the three processes of “dehydration”, “rinse”, and “wash” are displayed in order from the right as their contents. Then, on the front side (lower side in FIG. 1) of these character displays, the light emitting diodes 23a to
3d, 24a to 24c, 25a to 25d, 26a to 26
c is provided.

Each of the light emitting diodes 23a to 23d, 2 described above.
4a to 24c, 25a to 25d, and 26a to 26c, as shown in FIG. 5, the anodes are connected to the plus side terminal (+ V) of the DC power supply circuit through the transistors 27, respectively, and the cathodes are connected to the resistor 28. It is connected to the earth line via. And the microcomputer 13
Is a light emitting diode 23a-23d, 24a-24c, 25 by controlling on / off of the transistor 13.
Lighting and extinguishing of a to 25d and 26a to 26c are controlled.

Among the above setting items, "manual"
For other setting items except,
For each setting item, the most standard one, that is, "Course", which is a general course, "Standard", "Detergent", it is common to use concentrated detergent recently. "High" is located at the right end because the high water level is normal.

Therefore, the microcomputer 13
Selects one of the setting items in a predetermined order for each ON signal from the item selection switch 20. Specifically, "course" → "detergent" → "water level" → "manual" is selected in this order, "manual" is followed by "course", and so on. And
When the dial 16 is rotated while one setting item is selected, the microcomputer 13 washes the contents in a predetermined order each time one or a predetermined number of A-phase pulses PA are input.

Specifically, the microcomputer 13 detects the rotation direction of the dial 16 from the two-phase pulses PA and PB of A and B of the rotary encoder 15, and the rotation direction is the positive direction shown by the arrow A in FIG. In case of display 2
The contents displayed in 2 are sequentially selected from the right to the left, and in the case of reverse rotation, the contents displayed on the display unit 22 are sequentially selected from the left to the right. In this case, for the "manual" only, by rotating the dial 16 in the forward direction, "wash-rinse-dehydrate" to "rinse and dehydrate" → "wash and rinse" → "dehydrate" →
"Rinse"->"Wash" is selected in this order, and by reverse rotation, selection is made in the reverse order.

Here, the microcomputer 13 selects the contents at the left end or the contents at the right end when the dial 16 is rotationally operated in the forward or reverse direction and the amount of the rotational operation reaches a predetermined amount. Dial 1 from the time
No matter how much 6 is further rotated in the forward direction or the reverse direction, the contents at the left end or the contents at the right end are kept selected.

On the other hand, when a setting item is selected by the item selection switch 20, the microcomputer 13 initially causes the light emitting diode, for example, to display the rightmost one of the plurality of contents of the selected setting item to blink.
When contents are selected by the rotary encoder 15 in this state, the microcomputer 13 turns off the light emitting diode which has been blinking until then, and blinks the light emitting diode which displays the selected contents.

Next, the operation of the above configuration will be described. When a power switch (not shown) is turned on, the light emitting diode 23 indicating "standard" in "course" is displayed on the display unit 22.
a is in a blinking state, and the light emitting diode 24a indicating "concentration" in the "detergent", the light emitting diode 25a indicating "high" in the "water level", and all the light emitting diodes 26a to 26c in the "manual" are in the constant lighting state. Then, the setting item "course" is set by blinking the light emitting diode 23a.
Is displayed and the contents can be selected by rotating the dial 16. At this time, the fact that all the light emitting diodes 26a to 26c are turned on in the "manual" means that the entire process from washing to dehydration is performed.

As described above, when the power is turned on, the "standard" course, the "concentrated" detergent and the "high" water level are selected. Therefore, when washing is performed as it is, the start switch (not shown) is operated. Then, the washing operation suitable for the high water level and the concentrated detergent is performed in the standard course.

By the way, in some cases, it may be desired to wash at a course other than "standard", a detergent other than "concentrate", a water level other than "high" water level, or only wash, or only wash and rinse. is there. In this case, the dial 16 is rotated in the forward direction indicated by arrow A in FIG. 1 while the setting item "course" is selected. Then, the light emitting diodes which are in a blinking state move from the right side to the left side in order, so for example, when it is desired to select the "large" course, the rotation of the dial 16 is stopped when the light emitting diode 23c is in the blinking state. This makes it a "big game"
The course has been selected.

Here, when the pushbutton 21 is pressed once to turn on the item selection switch 20, the setting item "detergent" is selected and the "concentrated" light emitting diode 24a, which has been constantly lit, blinks. Become. At this time, the light emitting diode 23b of the "big game" course is constantly switched to the lighting state. In this state, if the dial 16 is rotated in the forward direction, the light emitting diodes which are in the blinking state move from the right side to the left side in order, so for example, when selecting "powder", the light emitting diode 24c is in the blinking state. Stop rotating the dial 16 at the open position. As a result, "powder" is selected.

Further, when the pushbutton 20a is pressed once again to turn on the item selecting switch 20, the setting item "water level" is selected and "high" which has been in the constantly lit state until then.
The light emitting diode 25a of is turned on and off. At this time, the "powder" light emitting diode 24a is constantly switched to the lighting state. In this state, when the dial 16 is rotated in the forward direction, the light emitting diodes which are in a blinking state move from the right side to the left side in order, so for example, when it is desired to select the "medium" water level, the light emitting diode 25c is in a blinking state. Stop rotating the dial 16 at the open position. This allows
This means that the "medium" water level has been selected. After that, when the start switch is operated, a washing operation suitable for powder detergent is performed at a medium water level in the course of a large game.

Further, for example, when it is desired to perform only the washing process or only the washing process and the rinsing process, the item selection switch 20 is turned on until the "manual" light emitting diodes 26a to 26c are in the blinking state. Select "Manual". When the dial 16 is rotated in the forward direction in this state, the light emitting diodes 26a to 26c are individually turned off or in a blinking state.
Only the light emitting diode 26c of blinks, or when the light emitting diodes 26c and 26b of "wash" and "rinse" blink, stop the rotation of the dial 16 and operate the start switch to wash only the wash stroke or wash. The operation of sequentially performing the stroke and the rinsing stroke is performed. At this time, when the "course" is selected as "standard", only the washing step in the "standard" course, or the washing step and the rinsing step are performed.

By the way, when a visually impaired person wants to wash, in this embodiment, when the power is turned on, the course is "standard", the detergent is "concentrated", and the water level is "high". Therefore, if the laundry is to be washed with the same setting, the start switch can be operated immediately. Also, if you want to select and set the course to, for example, "big game" other than "standard", the "big game" is located at the second position from "standard", so the dial 16 is rotated in the forward direction by an amount corresponding to that. Just operate it.

Here, the dial 1 to move the contents to the next contents
The rotation angle of 6 is fixed, and the constant rotation angle can be sensed depending on how many times the detent mechanism 19 gives detent. For example, in the case where the content shifts to the next content when the moderation feeling is obtained once, when the rotation of the dial 16 is stopped when the moderation feeling is obtained twice,
This means that the "big game" course has been selected. At this time, since a click sound is also generated at the same time, the rotation amount of the dial 16 can be sensed by the sound. This also applies to "detergent,""waterlevel," and "manual." Therefore, in each setting item, as long as it is memorized in what order the contents change from the right end. The washing operation can be performed with desired contents.

Moreover, in the present embodiment, when the dial 16 is rotated in the opposite direction (one direction) by a predetermined amount or more, the content remains selected at the right end.
If you do not know how much you have rotated 6 while rotating it in the forward direction, once rotate it in the opposite direction a little more, the contents will return to the right end, so dial again from there. It suffices to rotate 16 in the forward direction so that the desired content can be selected without fail.

7 and 8 show another embodiment of the present invention. The same parts as those in FIGS. 1 and 5 are designated by the same reference numerals and different parts will be described. The display unit 29 is provided with setting items of “water level”, “wash”, “rinse”, “dewatering”, and “course” in order from the rear side (upper side in FIG. 7). Then, on the display portion 30 of "water level", the character display of "small amount" and "high" are attached at a predetermined distance in the left-right direction, and an elongated rectangular frame 30a is attached to the lower side thereof. . Further, four light emitting diodes 31 are arranged side by side in the lateral direction in the frame 30a, and they display "high", "medium", "low", and "small amount" in order from the right.

The "wash" display portion 32 is provided with a 15-minute character display and a triangular frame 32a beside it.
Then, 15 light emitting diodes 3 are provided in the frame 32a.
3 are provided and they are 15 minutes from the right, 14
Minute …… Displays 1 minute.

The "rinse" display portion 34 is provided with a character display three times and a triangular frame 34a beside it.
Then, three light emitting diodes 35 are provided in the frame 34a.
Are provided three times, two times, and 1 from the right.
Display times.

The "dehydration" display portion 36 is provided with a character display three times and a triangular frame 36a beside it. Then, nine light emitting diodes 37 are provided in the frame 36a, and these are sequentially arranged from the right for 9 minutes, 8 minutes, ...
Display 1 minute.

A light emitting diode 39 is provided on the lower side of the “course”, “large”, “hand wash”, and “standard” character displays of the “course” display portion 38.

The light emitting diodes 31, 33, 35, 3
As shown in FIG. 8 (only one light emitting diode is shown), reference numerals 7 and 39 denote light emitting diodes 31a, 33a, 35a, 37a, 39a that emit red light and light emitting diodes 31b, 33b that emit green light, respectively. 35b, 37
b and 39b, which are transistors 40a and 40b controlled by the microcomputer 13, respectively.
The light emitting diode of the item which is turned on and off by the item selecting switch 20 is always turned on by the red light emitting diode, and the light emitting diodes of the other items are always turned on by the green light emitting diode.

Further, in front of the "course" display portion 38, there is provided a time display portion 41 as a 4-digit numerical value display portion composed of a 7-segment light emitting diode. The time display unit 41 normally displays the time. Then, when “wash”, “rinse” and “dehydrate” are selected, the time display section 41 is in a blinking state. And
When “wash” and “dewatering” are selected, the operating time is set by the time display unit 41, and when “rinsing” is selected, the number of times is set by the time display unit 41. ing. The time display unit 41 is also used when the start time of the selected operation is reserved and set.

Further, on the front side of the time display section 41, there are provided an up switch 42 and a down switch 43, which are located on the right side of the dial 16 and serve as changeover switches, for example, tactile switches. These two switches 42 and 43 are for switching the selection order of the setting items, and when the up switch 42 is operated to turn on the item selection switch 20, the setting items move from the "course" side to the "water level" side. When the down switch 43 is operated and the item selection switch 20 is turned on, the setting items are sequentially switched from the "water level" side toward the "course" side. When the water level is selected in the state where the up switch 42 is turned on, the "course" is selected next, and when the "course" is selected in the state where the down switch 43 is turned on, the next "Water level" will be selected.

In the above structure, when the power switch is turned on, the green LEDs 31b, 33b and 37b of the rightmost ones of the "wash", "rinse" and "dehydrated" light emitting diodes 31, 33 and 37 are turned on, and " The light emitting diode of "Course" is the rightmost red light emitting diode 39a.
Is lit up, and the display shows that "Course" is selected.

In this state, for example, when the up switch 42 is operated to turn on the item selecting switch 20, the setting items are sequentially selected from the "course" toward the "water level". Then, for example, when “dehydration” is selected, the light emitting diode 37 at the right end of the selected “dehydration” is switched to the constant lighting of the red light emitting diode 37a, and
The time display unit 41 is in a state of blinking while displaying "9".

At this time, the light emitting diode 39 at the right end of the "course" is switched to the constant lighting of the green light emitting diode 39b. In this state, when the dial 16 is rotated in the forward direction, the light emitting diode 37 that emits red light moves to the left side in order, and the time display portion 41 displays "8", "7" ...
Down display such as "0". Then, when the desired numerical value is reached, the rotation of the dial 16 is stopped. In addition, when the time display portion 41 becomes "0", "dehydration" means 0 minute, that is, the dehydration process is not executed, and none of the light emitting diodes 37 is turned on.

When "rinse" is selected, the light-emitting diode 34 at the right end of "rinse" is switched to the constant lighting of the red light-emitting diode 34a, and the time display section 4 is displayed.
1 becomes a state of blinking while displaying "3". Then, in the "dehydration", the light emitting diode 37 indicating the selected time is switched to the constant lighting of the green light emitting diode 37b. In this state, when the dial 16 is rotated in the forward direction, the light emitting diode 34a that emits red light moves to the left side in order, and the time display portion 39 displays "2", "1",
Down display such as "0". Then, when the desired numerical value is reached, the rotation of the dial 16 is stopped. Also here, when the time display portion 41 becomes "0", it means that the rinsing step is not executed, and the light emitting diode 34
Neither lights up.

When "wash" is selected, the light emitting diode 33 at the right end is switched to the constant lighting of the red light emitting diode 33a, and the time display section 41 is in a state of blinking while displaying "15". Then, in the “rinsing”, the light emitting diode 34 corresponding to the selected number of times.
Turns on the green light emitting diode 34b at all times. In this state, when the dial 16 is rotated in the forward direction, the light emitting diode 33a that emits red light moves to the left side in order, and the time display unit 39 displays "14", "13" ...
Down display such as "0". Then, when the desired numerical value is reached, the rotation of the dial 16 is stopped. Also at this time, when the time display portion 41 becomes “0”, it means that the washing process is not executed, and the light emitting diode 33
Neither lights up.

At the time of selecting such a setting item, for example, when the "washing" time is selected and set and the "rinsing" time is desired to be set again, the down switch 42 is operated to operate the item selecting switch 20. When is operated, the selection item moves from "wash" to "rinse", so it is not necessary to operate the item selection switch 20 many times such as "water level" → "course" → "dehydration" → "rinse". .

As described above, according to the present embodiment, the light emitting diodes of the item selected by the item selecting switch 20 become red and the light emitting diodes of the other items remain green, so that the item selecting switch 20 causes The selected item can be seen at a glance. When the item for which the time or the number of times has to be set, that is, "wash", "rinse", and "dehydration" is selected, the time display section 41 starts blinking, so the user sets a numerical value. You can intuitively understand what you have to do, and there is no risk of erroneous operation of selecting the next setting item without setting the time and number of times. The light emitting element is not limited to the light emitting diode and may be a lamp LCD or the like.

As described above, the present invention can obtain the following effects. According to the washing machine of the first aspect, since the contents of the setting items can be selected by rotating the dial of the setting device, the operability is improved as compared with the conventional case in which the switch has to be pressed many times. Moreover, when the setter is turned in one direction by a predetermined amount or more, the standard contents are selected, and therefore, the desired contents can be selected by turning the dial in the opposite direction by a predetermined amount. Therefore, even a person with an eye disorder can wash with desired contents.
