  FIG. 3 schematically shows a functional configuration of the control system of the drum type washing machine described above. The control device 5 includes various operation signals from an operation unit 49 including various buttons provided on the operation panel 4, a water level detection signal from the water level sensor 33, and a rotation sensor 50 that detects the rotation speed of the washing machine motor 9. The speed detection signal is input. And the control apparatus 5 drives the water supply valve 34, the drain valve 24, the washing machine motor 9, the circulation pump 26, the said display part 43, etc. which are not shown in figure based on the said various input signals and the control program memorize | stored previously. Control through the circuit.

Here, the “standard” course, the “careful” course, and the “lightly dirty” course corresponding to the automatic driving course in this embodiment will be described.
In the “standard” course, as shown in FIG. 5, the following washing process, first rinsing process (rinsing process), second rinsing process (rinsing process), and final dehydrating process (dehydrating process) are executed. In FIG. 5, the shaded area indicates a state where the corresponding device or operation is functioning.

Washing process: This consists of a water supply operation and a stirring operation.
Water supply operation: In this operation, the water supply valve 34 is opened to supply water into the water tank 6 to a water level equivalent to 30 L (liter), and the drum 12 is intermittently rotated at 50 rpm. At this time, the intermittent mode of the drum 12 is driven for 20 seconds (energization of the washing machine motor 9) and stopped for 10 seconds (disconnection of the washing machine motor 9). Water is supplied into the water tank 6 by this water supply, and at the initial stage of water supply, the detergent is supplied into the water tank 6 (in the drum 12) by water supply. In this water supply operation, the laundry is supplied with water while being washed by so-called tapping (the drum 12 is raised to a substantially intermediate height by the rotation of the drum 12 and then dropped).

    Stirring operation: The stirring operation in this washing process corresponds to a washing operation. In this stirring operation, the washing machine motor 9 is alternately energized at 50 rpm for 20 seconds and then turned off for 10 seconds. The execution time of this stirring operation is 15 minutes, and the drum 12 is intermittently rotated by the intermittent operation of the washing machine motor 9. The laundry in the drum 12 is agitated by the intermittent rotation of the drum 12. Therefore, the washing machine motor 9 functions as a drive source for stirring the laundry in this washing process and the following first and second rinsing processes. Further, the circulation pump 26 is repeatedly driven (energized) for 5 seconds and stopped (disconnected) for 5 seconds. Thus, the laundry is beaten and washed by the drum 12 in the water storage state, and the water in the water tub 6 is intermittently sprinkled onto the laundry from above by the circulation pump 26.

First rinsing process: This consists of a draining operation, a dehydration 1 operation, a water supply operation, and a stirring operation.
Draining operation: Draining is performed by opening the drain valve 24.
Dehydration 1 operation: This dehydration 1 operation corresponds to an intermediate dehydration operation. In this dehydration 1 operation, the drum 12 is rotated at a high speed to 1500 rpm while the drain valve 24 is opened. Do this for 1 minute. Thereby, the water containing the detergent in the laundry is dehydrated.

Water supply operation: This is to supply water into the water tank 6 to a water level corresponding to 30 L (liter) by opening the water supply valve 34 and to continuously rotate the drum 12 at 100 rpm. The laundry is stuck to the inner surface of the rotary drum 12 and rotated by the centrifugal force generated by the rotation.
Stirring operation: The stirring operation in this rinsing process corresponds to a rinsing operation. In this stirring operation, an operation with the same operation content as the stirring operation in the washing process is performed for 2 minutes. Thereby, the laundry is beaten and washed by the drum 12 in the water storage state, and the water in the water tub 6 is intermittently sprinkled on the laundry from above by the intermittent operation of the circulation pump 26.

Second rinsing process: This is different from the first rinsing process in that the rotation speed of the drum 12 in the water supply operation is 50 rpm, and the other operation contents are the same as the first rinsing process. The dehydration 2 operation in the second rinsing process corresponds to an intermediate dehydration operation.
Final dehydration process: This consists of a draining operation and a dehydrating operation.
Draining operation: This is the same as the draining operation in the first rinsing process.
Dehydration operation: The drum 12 is rotated at a high speed up to 1000 rpm with the drain valve 24 open. Do this for 4 minutes. Thereby, the laundry is dehydrated.

  Next, the “careful” course will be described with reference to FIG. Compared to the “Standard” course, this “careful” course has a longer run time for the stirring operation of the washing process as 30 minutes, a third rinsing process, and an execution time of the dehydration operation for the final dehydration process. The difference is that it is 10 minutes. The driving details of the third rinsing stroke in this “careful” course are the same as the driving details of the second rinsing stroke.

Next, the “light dirt” course will be described with reference to FIG. This “lightly soiled” course differs from the “standard” course in that the rinsing process is only the first rinsing process.
The control device 5 has functions as a modest correspondence changing means and control means, and the control contents of the control device 5 including these functions will be described with reference to FIG. The user sets the driving course by operating the operation panel 4 in a state where the laundry is accommodated in the drum 12. In step S1, the control device 5 determines whether or not any of the driving courses has been set. If it is determined that any of the courses has been set, the control device 5 proceeds to step S2 and determines whether the “memory” course has been selected. Judge whether or not.

  If “NO” in the step S2, the process shifts to a step S3 to determine whether any of the “standard” course, the “careful” course, and the “lightly dirty” course among the automatic driving courses is selected. . If “YES”, the process proceeds to step S4, and it is determined whether or not a conservative content (any one of “water saving”, “power saving”, “silent”, and “saving time”) is designated. If it is determined that there is a modest content specification and it is determined in step S5 that a start operation has been performed by the start / pause button 42, the process proceeds to step S6, and the "standard" course, The automatic course selected from the “course” and the “lightly soiled” course is changed according to the specified content of the moderation (moderate correspondence changing means).

That is,
(A) When the “standard” course is selected and “water saving” is designated, the operation content of the “standard” course shown in FIG. 5 is changed as shown in FIG. In addition, the “standard” course changed by “water saving” is referred to as “standard / water saving” course. Changes in the “Standard / Water Saving” course with respect to the “Standard” course are indicated by “*” in FIG. In the “Standard / Water Saving” course, the drum speed of the dehydration 1 operation in the first rinsing process and the dehydration 2 operation in the second rinsing process is changed to “1700 rpm” (“1500 rpm” in the “Standard” course) and the first rinsing process The amount of water supply in the process and the second rinsing process is changed to “25 L” (“30 L” in the “standard” course, respectively).

  Here, in the moderation response changing means, “changing the driving content of the automatic driving course” means, in this embodiment, every time the automatic driving course is selected and the modest content is designated, the driving content is set as described above. In addition to this, in addition to this, an automatic driving course (in this case, the above-mentioned “standard / water-saving” course) in which the driving contents are changed according to the modest contents is created and stored in advance, and automatic driving is performed. Each time a course is selected and conservative content is specified, the stored modified automatic driving course ("Standard / Water Saving" course) is read, and the read modified automatic driving course ("Standard / Water Saving") is read. "Course") includes changing and setting the previous automatic driving course ("Standard" course).

  (B) As a conservative content, when “power saving” is designated for the “standard” course, the operation content of the “standard” course shown in FIG. 5 is shown in FIG. 9 and FIG. Change to The “standard” course changed in this “power saving” is called “standard / power saving” course. In this “Standard / Power Saving” course, the period of intermittent drum rotation of the stirring operation (washing operation) in the washing process is set to “5 seconds on (energized), 115 seconds off (energized)” (“20 seconds in the“ standard ”course). On, 10 seconds off "), and the execution time of the stirring operation is changed to" 120 minutes "(" 15 minutes "in the" standard "course). As a result, in the “standard / power saving” course, the total energization time of the washing machine motor 9 during the washing process is changed to “5 minutes” (“10 minutes” in the “standard” course).

Further, the circulation pump 26 is not operated in the stirring operation in the washing process (see FIG. 10).
(C) As a conservative content, when “silent” is designated for the “standard” course, the operation content of the “standard” course shown in FIG. 5 is changed as shown in FIG. . The “standard” course changed by this “silent” is called “standard / silent” course. In the “Standard / Silent” course, the drum rotation speed of the first dehydration stroke in the first rinsing process and the drum rotation speed of the second dehydration stroke in the second rinsing stroke are set to “1000 rpm” (“1500 rpm” in the “Standard” course), respectively. The water supply amounts in the first rinsing process and the second rinsing process are each changed to “35L” (each “30L” in the “standard” course).

  (D) As a conservative content, when “save time” is specified for the “standard” course, the operation content of the “standard” course shown in FIG. 5 is changed as shown in FIG. To do. Note that the “standard” course changed in this “time saving” is called “standard / time saving” course. In this “Standard / Save Time” course, the execution time of the first dehydration operation in the first rinsing process and the second dehydration operation in the second rinsing process was changed to “30 seconds” (“1 minute” in the “Standard” course). The drum rotation speeds of the dehydration 1 operation in the first rinsing process and the dehydration 2 operation of the second rinsing process are respectively changed to “1700 rpm” (“1500 rpm” in the “standard” course), respectively. Change the water supply amount in the rinsing process to “25L” (each “30L” in the “Standard” course), and “2 minutes” in the final dehydration process (4 minutes in the “Standard” course) And the drum rotational speed of the dehydration operation is changed to “1700 rpm” (“1000 rpm” in the “standard” course).

  (E) As a conservative content, when “water saving” is designated for the “careful” course, the operation content of the “careful” course shown in FIG. 6 is changed as shown in FIG. . In addition, the “careful” course changed in “water saving” is called “careful / water saving” course. In the “careful / water-saving” course, the following operation details are changed with respect to the “careful” course (“*” in FIG. 13 is changed). The drum rotation speeds of the dehydration 1 operation in the first rinsing process, the dehydration 2 rinsing operation in the second rinsing process, and the dehydration 3 operation in the third rinsing process are respectively changed to “1700 rpm” (“1500 rpm” in the “careful” course). At the same time, the water supply amounts in the first rinsing process to the third rinsing process are each changed to “25 L” (“30 L” in the “careful” course).

(F) As a conservative content, when “water saving” is designated for the “lightly soiled” course, the “lightly soiled” course shown in FIG. 7 is changed as shown in FIG. The “light dirt” course changed with this “water saving” is called “light dirt / water saving” course. In this “light dirt / water saving” course, the drum rotation speed of the first dehydration operation in the first rinsing process is changed to “1700 rpm” (“1500 rpm” in the “light dirt” course) and the water supply amount in the first rinsing process is changed to “ 25L "(" 30L "for the" lightly dirty "course).
In step S7 following step S6 described above, the above-mentioned “standard / water saving” course, “standard / power saving” course, “standard / silent” course, “standard / saving time” course, The automatic driving course of either the “careful / water saving” course or the “light dirt / water saving” course is executed (changed operation control means).

Here, among the “standard / water saving” course, “standard / power saving” course, “standard / silent” course, “standard / saving time” course, “careful / water saving” course, “light dirt / water saving” course,
(A) When the “standard / water saving” course (see FIG. 8) is executed, the drum rotation speed in the dehydration 1 operation and the dehydration 2 operation is the same as that in the dehydration 1 operation and the dehydration 2 operation in the “standard” course. By setting the drum rotation speed to “1700 rpm” higher than “1500 rpm”, the effect of removing the detergent in the laundry (rinsing effect) is high, and the amount of water required for rinsing can be reduced. In this embodiment, the amount of water supplied in each rinsing process is changed from 60 L (30 L × 2) in the case of the “standard” course to 50 L (25 L × 2), and the actual amount of water used is reduced without reducing the rinsing effect. doing.

  In this way, if the user wishes to save washing water and designates “conserving water” which is a conservative content, the control device 5 automatically changes the automatic operation course to the operation content corresponding to water saving. On the user's side, it is not necessary to take the troublesome and difficult-to-understand response of changing the operation content in response to saving water (so-called manual setting), so that the user can easily save water on the automatic driving course. In addition, it can maintain the same cleaning effect as the original automatic driving course (in this case, the “standard” course).

(B) When the “standard / power-saving” course is executed in step S7, as shown in FIGS. 9 and 10, the drum rotation time limit in the stirring operation (washing operation) in the washing process is one time. Since the total energization time of the washing machine motor 9 is shortened from 10 minutes to 5 minutes, power saving can be achieved. Here, since the drum rotation-off time per one time is changed to be as long as 115 seconds, that is, the washing time when the so-called laundry is soaked is “115 minutes” (in the “standard” course, “ 5 minutes "), the cleaning effect can be prevented from being lowered.
In this way, if the user wishes to save time and designates “power saving”, the control device 5 automatically changes the automatic driving course to the operation content corresponding to power saving. Therefore, it is possible to easily save power with respect to the automatic driving course and to maintain the same cleaning effect as that of the original automatic driving course.

(C) When the “standard / silent” course is executed in step S7, as shown in FIG. 11, the drum rotational speed of the dehydration 1 operation and the dehydration 2 operation is reduced to “1000 rpm”. Therefore, driving noise can be reduced. In this case, there is a concern that the rinsing effect may be reduced due to the reduction in the drum rotation speed. Therefore, it is possible to expect a rinsing effect equivalent to that of the “standard” course, and thus a cleaning effect.
As described above, if the user desires to reduce noise and designates “silent”, the control device 5 automatically changes the automatic driving course to the driving content corresponding to the silent sound. Therefore, quiet operation can be easily achieved with respect to the automatic driving course, and the cleaning effect substantially the same as that of the original automatic driving course can be maintained.

  (D) When the “standard / save time” course is executed in step S7, as shown in FIG. 12, each execution time of the dehydration 1 operation and the dehydration 2 operation is changed from “1 minute” to “30”. "Second" and the execution time of the dehydration operation in the final dehydration process has been changed from "4 minutes" to "2 minutes", so the execution time of the automatic operation course has been shortened (4 minutes in total) And save time. In this case, there is a concern that the rinsing effect will be reduced by saving time for the dehydration 1 operation and the dehydration 2 operation, but the drum rotation speed in these dehydration 1 operation and dehydration 2 operation is increased from “1500 rpm” to “1700 rpm”. Therefore, the rinsing effect can be maintained even if the execution time of the dehydrating operation is shortened. In addition, there is a concern about a decrease in the dewatering rate by shortening the execution time of the dewatering operation in the final dewatering process, but in this embodiment, the drum rotation speed is increased from “1000 rpm” to “1700 rpm”. There is no decrease in dehydration rate.

  As described above, when the user desires to save time and designates “saving time”, the control device 5 automatically changes the automatic driving course (“standard” course) to the driving content corresponding to the saving time. Therefore, also in this case, the user can easily save time with respect to the automatic driving course, and can maintain substantially the same cleaning effect as the original automatic driving course.

  (E) When the “careful / water-saving” course is executed in step S7, as shown in FIG. 13, each water supply in the first, second and third rinsing steps is performed on the “careful” course. Since the amount is reduced from “30L” to “25L”, respectively, the amount of water can be reduced by 15L in total for the “careful” course. In this case, the drum rotation speed of each dehydration 1 operation, dehydration 2 operation and dehydration 3 operation in the first, second and third rinsing steps preceding each water supply operation is increased from “1500 rpm” to “1700 rpm”. Therefore, by making the removal effect of the detergent portion high in advance, it is possible to guarantee a decrease in the rinsing effect due to the decrease in the amount of rinsing water, and eventually the rinsing effect can be maintained.

  In this way, if the user wishes to save water for the “careful” course and designates “water saving”, the controller 5 operates the automatic driving course (“careful” course) corresponding to water saving. Since the contents are automatically changed, the user can easily save water in the automatic driving course, and can maintain the same cleaning effect as the original automatic driving course.

  (F) Also, when the “light dirt / water saving” course is executed in step S7, the water supply amount in the rinsing process is reduced from “30L” to “25L” as shown in FIG. The amount of water can be reduced by 5 L with respect to the “light dirt” course. In this case, since the drum rotation speed of the dehydration 1 operation preceding the water supply operation is increased from “1500 rpm” to “1700 rpm”, the amount of rinse water can be reduced by increasing the detergent removal effect in advance. Therefore, the rinsing effect can be kept low, and the rinsing effect can be maintained.

  Thus, if the user wishes to save water for the “lightly dirty” course and designates “water saving”, the control device 5 corresponds to the automatic driving course (“lightly dirty” course) for water saving. Since the operation contents are automatically changed, the user can easily save water in the automatic operation course, and can maintain the same cleaning effect as the original automatic operation course.

In step S8 following step S7 described above, the changed automatic driving course executed in step S7 is stored in the nonvolatile memory 39. In the stored automatic driving course, when the “memory” course is specified in the above-described step S2 (“YES”), and there is a start operation in step S11, the stored automatic driving course is displayed in step S12. It will be read and executed.
If “NO” in step S3 and “NO” in step S4, the process proceeds to step S9. If it is determined in step S9 that a start operation has been performed, it is set in step S10. The course is executed.

  As described above, in the above-described embodiment, the preference setting button 44 is provided as input means for designating conservative content, and the discreet correspondence changing means in the control device 5 is the discreet content designated by the preference setting button 44. Therefore, the operation content of the automatic driving course is changed, and the changed driving control means in the control device 5 executes the automatic driving course changed by the modest response changing means. If you specify the modest content you want, such as the laundry environment at that time or the user's preference, such as a quiet night, you can automatically change the driving content according to the modest content , This modified automatic driving course can be executed, even if the user is into the driving content of the automatic driving course, the modest content that he wants easily It is possible to carry out the suits laundry.

  Furthermore, in the above embodiment, when the driving content is changed according to the modest content in the automatic driving course, when there is a concern about the cleaning effect such as the washing effect, the rinsing effect or the dehydrating effect, In order to secure this, since the operation content other than the operation content changed according to the modest content is changed, it is possible to maintain a cleaning effect substantially equivalent to the automatic operation course before the change.

In the above embodiment, when “water saving” is designated, the dehydration speed of the intermediate dehydration operation (dehydration 1 operation, dehydration 2 operation) of the automatic operation course is increased and the rinsing process (first rinsing process, second rinsing process). Since the amount of water used in the rinsing process) is reduced, the reduction of the rinsing effect can be prevented while saving water.
Further, in the above embodiment, when “power saving” is designated, the total energization time of the washing machine motor 9 in the stirring operation (washing operation) of the washing process of the automatic operation course is shortened and the total interruption of the washing machine motor 9 is changed. Since the power transmission time has been changed for a long time, it is possible to prevent the deterioration of the washing effect due to the soaking and washing effect while saving power.

In the above embodiment, when “silent” is designated, the dehydration speed of the intermediate dehydration operation (dehydration 1 operation and dehydration 2 operation) of the automatic operation course is lowered and the water supply amount in the subsequent water supply operation is increased. Therefore, it is possible to reduce operation noise during dehydration and to prevent a decrease in rinsing effect.
Further, in the above embodiment, when “saving time” is designated, the dewatering rotation speed (dehydration 1 operation, dewatering 2 operation and dewatering rotation speed (drum rotation speed) of the final dewatering process) of the automatic operation course is changed to a high value. At the same time, since the execution time of the dehydrating operation is changed to be shorter, the time for the automatic driving course can be shortened, that is, the time can be saved. In this case, since the rinsing effect is increased by increasing the dehydration speed in the first and second rinsing steps, the amount of water supplied in the first and second rinsing steps can be reduced (see FIG. 5). Water supply amount “25L” × 2 in FIG. 12 with respect to water supply amount “30L” × 2 in the process).

It is considered that some users tend to take a setting pattern in which a specific automatic driving course is always selected and a specific content is always designated as a conservative content when washing is performed in the automatic driving course.
In this regard, according to the above embodiment, when there is a change in the driving content based on the designation of the conservative content for the automatic driving course, the changed automatic driving course is stored in the nonvolatile memory 39 and the washing operation is started. The automatic driving course previously stored in the non-volatile memory 39 can be specified and executed by selecting the “memory” course, so it is easy to always specify the same discreet content in the same automatic driving course. It is possible to designate and execute an automatic driving course having the same driving content as the previous time, which is excellent in convenience.

(Second Embodiment)
FIG. 15 shows a second embodiment. The second embodiment is different from the “standard / water-saving” course of the first embodiment in the change of the operation content when “water-saving” is designated for the “standard” course. In the first embodiment, as shown in FIG. 8 with respect to the “standard” course of FIG. On the other hand, in the second embodiment, as shown in FIG. 15, the water supply amount of each water supply operation in the first rinsing process is set to “10L” (in the “standard” course, as compared with the “standard” course in FIG. In addition, the shower rinsing operation is performed twice in place of the stirring operation (the rinsing operation) in the first rinsing process in the “standard” course.

  In the shower rinsing operation, the drum 12 is rotated at 100 rpm and the circulation pump 26 is continuously operated, for example, for one minute. Thereby, the laundry is rotated in a state of sticking to the inner surface of the drum 12, and the sprinkled water passes through the laundry by centrifugal force.

  In the second embodiment, it is possible to save water by reducing the water supply amount as described above. Then, there is a concern about the reduction of the rinsing effect due to saving water, but this can be solved by providing two shower rinsing operations instead of the rinsing operation. That is, the rinse operation requires a relatively large amount of water. On the other hand, in the shower rinsing operation, the drum 12 is increased to 100 rpm, thereby increasing the centrifugal force and sticking it to the inner surface of the drum 12 of the laundry and facilitating the passage of the laundry by the centrifugal force. As a result, the amount of detergent contained in the laundry can be effectively reduced, and further, the water in the tub can be continuously poured into the laundry by the continuous operation of the circulation pump 26, and rinsing is performed even if the water supply amount is reduced as a whole. The effect can be maintained sufficiently. The shower rinsing operation may be performed once. In this case, the water supply amount of the water supply operation in the first rinsing process may be changed from “10L” twice to “15-25L” once.

(Third embodiment)
FIG. 16 shows a third embodiment. The third embodiment is different from the first embodiment in the change in operation content in the “standard / water saving” course. In the third embodiment, as the rinsing process, a third rinsing process is provided in addition to the first rinsing process and the second rinsing process. Then, the drum rotation speed in each water supply operation of the first rinsing process and the second rinsing process is changed to “50 rpm” (“100 rpm” in the water supply operation of the first rinsing process in the “standard” course), and the subsequent water supply operation Is changed to “17 L” (“30 L” in the “standard” course). The third rinsing stroke has the same operation content as the first and second rinsing strokes after these changes.

In the third embodiment, the total water amount (used water amount) in the rinsing process is “17 L” × 3 = “51 L”, and is based on the total water amount in the “standard” course rinsing process (“30 L” × 2 = “60 L”). Less. In this case, there is a concern about a decrease in the rinsing effect due to a decrease in the amount of water supplied, but the rinsing effect can be maintained because the number of rinsing strokes is increased.
In each of the above embodiments, the driving contents corresponding to the modest contents are changed for the “standard” course, the “careful” course, and the “lightly dirty” course as the automatic driving course. For other automatic driving courses, the driving content corresponding to the modest content may be changed.

  According to the embodiment described above, in a washing machine capable of executing a preset automatic driving course, the automatic operation is performed in accordance with the content of the mode specified by the input unit and the mode of the mode specified by the input unit. A modest response change means for changing the driving content of the course and a change operation control means for executing the automatic driving course changed by the moderation response change means are provided, so that the user selects the modest content for the automatic driving course. Then, according to the modest content, the operation content of the automatic operation course can be automatically changed and executed.
