Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a washing machine.

(B) Conventional technology Conventionally, we have multiple types of course programs with different process times and partial course programs that perform partial washing operations such as kami->dehydration, wash-rinse, etc. A washing machine that selects and executes these programs according to the washing machine is disclosed in Japanese Patent Publication No. 60-39399 (DO6
F 33102).

In recent years, fully automatic washing machines like this have become popular and the operability of washing machines has improved, so even people who are not very familiar with how to operate a washing machine can now do everything from washing to spin drying with a single button. Now it can be done automatically.

However, for those who are not familiar with the operation of washing machines, it is still difficult to select a program suitable for the condition of the laundry from among the many programs in the washing machine. Ta.

Therefore, as a means to solve this problem,
As disclosed in Japanese Patent No. 1-22889 <D06F 33102), there is a washing machine that automatically sets frequently used programs immediately after the power is turned on. However, with this washing machine, the automatic program settings are only effective for the first wash, and the power must be turned off before the next wash, and the programs specified by the manufacturer are not necessarily used in all households. I can't say it happens frequently.

Furthermore, it is conceivable to display the program executed last time as it is, but this would cause confusion if the washing machine is equipped with special programs such as partial course programs.

(c) Problems to be Solved by the Invention The present invention aims to improve the operability of a washing machine.

(d) Means for Solving the Problems The washing machine of the present invention stores in its memory a plurality of courses in which washing, rinsing, and spin-drying processes and different process times are appropriately combined, and a plurality of courses are selected. λ1, the control device according to Art. It is configured so that a predetermined course is automatically initialized and displayed immediately after the power is turned on, and after a certain course program is finished, this :J-S is set and displayed again, or the predetermined course is set and displayed. The control device is provided with a key for manually inputting a signal to select whether to do so.

(e) In other words, in the will of the user, if the predetermined course specified by the manufacturer is the one that is frequently used, then after the course is completed, the predetermined course of Party B will be set and If the frequency is low, select the high frequency course using the key so that it is set repeatedly.

(to) Examples Embodiments of the present invention will be described with reference to the drawings.

, display of the current time or remaining process time (40), display of the scheduled end time of washing (41), display of whether the program is set to repeat (42), and buzzer display (43).
This will be announced by the flashing ED.

(44> is a setting area where various operation setting keys are consolidated, and (45), (46), and (47) are for changing the settings of washing, spin-drying process time, and number of rinses individually when you select your favorite course. By pressing the time change key, the change time (number of times) is displayed on the process time display <40). (48) is a pre-soak washing selection key for selecting whether or not to soak the laundry in the washing liquid without rotating the rotor for a predetermined period of time before the washing process, and each time the key is pressed, the pre-soaking display (38) is displayed. The point disappears. (49) is a water rinsing selection key for selecting whether or not to perform the rinsing process while supplying water; each time the key is pressed, the water rinsing display (3)
9) turns on and off. (50) is the water flow strength selection key,
Each time it is pressed, the water flow intensity display (35) turns on and off cyclically. (51) is a buzzer key for selecting whether or not a buzzer is required to notify when the program ends; each time it is pressed, the water flow intensity display (43) ) will turn on and off. (52) will be described later, but after the program ends, it will automatically return to the initial setting state (the washing machine in this example will automatically set the "approximately 18 minute course" immediately after the power is turned on. This is a repeat key for selecting whether to automatically set the current program contents again.Each time the key is pressed, the above-mentioned repeat display (42) turns on and off, and when it is turned off, , the program returns to its initial state. (53) and (54) are keys for selecting whether to change the current time or set a laundry reservation time;
(55) and (56) are hour and minute change keys, which are used to change the display of the current time (40) and the display (41) of the scheduled end time of washing. (57> is a completion key that is pressed at the end of the time change operation.

Membrane switches (58) are arranged on the bottom surfaces of these operation setting keys (45) to (57), and when pressed, the membrane switches (58) are activated.
The corresponding contact is closed, and the closing signal is input to the microcomputer (6).

Now, the setting area (44) has a lid (59) that can be opened and closed.
), and four operation keys (60) to (63) are arranged on this lid (59). Each of these operation keys (60) to (63) is constituted by a flexible piece that is partially continuous with the lid (59), and is bent downward when pressed and returns to its original position when released. The lid body (59) is provided on the bottom surface of each of the operation keys (60) to (63).
When the is closed, each of the operation setting keys (45) to (57)
Among these, protrusions (64) are vertically provided on two predetermined keys, which abut or closely face each other.

That is, the operation key (60) is only used to change the water level, and by pressing it with the lid (59) closed, the current time change selection key (53) and the laundry reservation time setting can be changed. The selection key (54) can be pressed at the same time. Each time a signal is simultaneously input from both selection keys (53) and (54), the microcomputer (6) accepts a change in the water level and simultaneously turns on and off the water level display (34) cyclically.

Hereinafter, when the lid body (59>) is closed, the operation key (61) is used to change the course, and by pressing it, the minute change key (56) and the completion key (57) are pressed. ) can be pressed at the same time.And,
Every time signals are input from these keys (56) and (57) at the same time, the microcomputer (6) accepts a course change and simultaneously displays the course setting status display (37), water flow strength display (35), and water level display. (34) is turned on and off in the corresponding state.

Figure 7 shows the program content of each course. In the same figure, when each course is set to ``Toronko'', ``Wool'', and ``Blanket'', the water flow display <35) will all turn off, but this is because each course is different from the other as shown in Figure 8. This is because it is washed with a special water stream, and each course is unique, so it is expressed by turning off all LEDs without installing a new dedicated display LED.Therefore, the cost does not increase. In FIG. 8, the horizontal axis represents time, and the vertical axis represents the rotational speed of the rotor.

Also, if you select the "Mud" course, the water level display (
34) is also turned off, but since only the 1-dronko course is washed at a water level lower than the low water level, this is expressed by turning off all the LEDs.

In addition, if you select "Preference", the water level will be automatically set to standard water flow and high water level.The water flow for "Mud", 'Wool' and "Blanket" courses and the water level for "Mud" course will be changed. is not marked, and everything else can be changed freely.

The operation key (62) is for pre-washing, and when pressed, the pre-set key (48) is pressed.
and the water injection rinse key <49) can be pressed at the same time. When signals are input from these keys (48> (49)) at the same time, the microcomputer (6) calculates backwards from the time displayed on the reservation time display (41) and calculates the required time before the set course. The machine waits until then and operates the washing machine so that the course finishes at the reserved time.

The operation key (63) is used to start the course, and when pressed, the water flow key (50) is used to start the course.
) and the buzzer key (51) can be pressed at the same time, and when signals are input from these keys (50) and (51) at the same time, the microcomputer (6) immediately starts the setting course.

In addition, a waterproof sheet <65) is pasted on the upper surface of each of the operation setting keys (45) to (57) and each operation key (60) to (63), and the sheet 1-<65) At the top, there are displays corresponding to the various keys.

As described above, in this embodiment, by simultaneously suppressing two specific operation setting keys, different operation settings can be performed, which reduces the number of operation setting keys and saves space. It is possible to create a design with plenty of leeway. Moreover,
Since operation keys for simultaneous operation are provided on the lid (59), keys for complicated operation settings are shielded by the lid (59) so that the minimum operations can be performed using the operation keys. You can also do this, and in this way even those who are not familiar with it can easily operate it. Note that the number of operation setting keys pressed at the same time is not limited to two.

Finally, the operation of the washing machine of this embodiment will be explained according to the flowchart of FIG.

When the Kangen switch (59) is turned on, the microcomputer (6) automatically sets the operating state of the washing machine to the course "1 about 18 minutes" and at the same time sets the operating state of the washing machine to the course corresponding to "about 18 minutes". The display (37a), high water level display (34a), and strong water flow display (35a) are turned on (S-1>).

If the user wants to change this operating state, he/she can change it using the operation setting key or operation key (assuming that the user changes it to the "standard" course), and then repeats this changed course (r standard" course) twice. If you plan to execute the above repeatedly,
Operate the repeat key (52) and keep the repeat display (42) lit (S-2>.Next, press the reserved washing start operation key (62) or start operation key (63). (S-3) and executes the program (S-4).Then, the microcomputer (6)
When the course program ends, the above-mentioned repeat display (42
) is lit or not (5-5), and if it is lit, the operating status is automatically changed to the current course ("Standard" course).
and at the same time display the "standard" course (37b),
The standard water flow indicator (35b) and high water level indicator (3aa) are turned on.

Further, if the repeat display (42) is not lit, the operating state is automatically set and displayed to the initial setting state of "about 18 minutes" course.

In this way, if you operate the repeat key (52) and keep the repeat display (42> lit), in (S-2) you can change the course to "Favorite, Course" and change the time for each process. For example, if you set the washing time to zero and the number of rinses to zero and set a course that only performs dehydration, there is no need to reset the dehydration-only course every time you finish it, just by operating the start operation key (63). You can repeat the course as many times as you want.Also, even if the most frequently used course is not the 18 minute course, you can repeat that course many times in a row by simply changing to the most frequently used course. Can be repeated.

(g) Effects of the Invention The washing machine of the present invention can be used in a washing machine according to the user's will, if a predetermined course specified by the manufacturer is used frequently and repeatedly in the user's household, then the washing machine can be used after the user has finished the predetermined course. If the course is infrequently used, the frequently used course or the course to be executed repeatedly can be set automatically after the course is completed. Since the selection can be made using the keys, it is possible to omit the setting work when repeating the course, and it has excellent operability.
