  The bath water setting has a plurality of bath water setting contents, for example, “not used”, “washing”, “rinse 1”, and the like, which are desired from the setting contents. The bath water settings can be selected.

  Washing process setting, rinsing process setting, dehydration process setting and drying process setting are set (adjusted) in detail for the operation intensity of each process from the washing course contents, washing drying course contents and drying course contents selected by the user. It is used when performing so-called manual operation.

  Specifically, in the setting of the washing process, the desired washing time can be selected in minutes with the washing time as the setting content, and in the rinsing process setting, the desired number of rinsing operations can be selected with the setting number of rinsing as the setting contents. In the dehydration process setting, a desired dehydration time can be selected in minutes with the dehydration time as a setting content. The drying process settings include the contents of the drying process with different operating strengths, such as “automatic”, “quality finish”, “iron”, “reducing shrinkage”, etc. In addition, the drying process setting includes a drying time as a setting content, and a desired drying time can be selected in units of 10 minutes.

  Next, the operation of the washing machine 1 configured as described above will be described.

  First, in an initial state when the power is turned on when the “ON” of the power key 70 is pressed, for example, “washing” is displayed on the operation mode display portion 71 by selecting the washing mode, and the washing course is displayed. By selecting “standard” from the contents of the laundry courses that are included, “standard” in the course content display section 72 is displayed. In addition, the current time is displayed on the number display unit 74 in the liquid crystal display panel 80, and “time” is displayed on the display content display unit 75. Then, the washing key 54, the rinsing key 55, and the dehydration key 56 are turned on to indicate that the washing process, the rinsing process, and the dehydration process are executed. At this time, in the liquid crystal display panel 80, a white backlight is turned on, and the background color of the panel is set to white.

  In order to select the washing course contents from this state, the washing course contents are changed from “standard” → “hot mist” → “speedy” → “soft finish” every time the operation dial 90 is rotated clockwise by a predetermined angle. ”→“ Careful ”→“ Memory ”→“ Small amount ”→“ Dry ”→“ Blanket ”→“ Bath cleaning ”The operation dial 90 is further turned clockwise from“ Bath cleaning ”. Return to "Standard". On the other hand, when the operation dial 90 is turned counterclockwise, the contents of the washing course are selected in the reverse order.

  The selection of the washing course contents can also be performed by pressing the washing mode key 53. In this case, the course is operated in the same order as when the course rotates the operation dial 90 clockwise each time the key operation is performed. To be selected.

  When the laundry course content is selected as described above, the course content display unit 72 displays the selected laundry course content by turning on a light emitting diode corresponding to the selected laundry course content. .

  After the selection of the washing course content is completed, the start / pause key 62 is pressed to start the operation of the washing machine 1 based on the selected washing course content. At that time, the backlight of the liquid crystal display panel 80 is turned on from white to blue, and the background color of the panel is changed to blue so that the user is informed that the washing machine 1 is in operation. .

  Note that the current time displayed on the number display portion 74 in the initial state disappears when the laundry course content is first switched.

  In order to select the washing / drying mode from the initial state in which the washing mode is selected, first, the laundry / drying mode key 52 is pressed. Then, “washing and drying” in the operation mode display section 71, “standard” in the course content display 72 and “automatic” in the drying process content display section 73 are displayed, and the washing key 54, the rinsing key 55, the dehydration key 56, The drying key 57 is turned on to indicate that a washing process, a rinsing process, a dehydrating process, and a drying process are executed. This indicates that the mode has been switched to the washing / drying mode. At this time, in the liquid crystal display panel 80, the white backlight is turned on, and the background color of the panel is set to white.

  Every time the operation dial 90 is rotated clockwise by a predetermined angle from this state, the content of the washing / drying course is “standard” → “hot mist” → “speedy” → “careful” → “memory” → “blank” When the operation dial 90 is further rotated clockwise from “Blanket”, the setting returns to “Standard”. At this time, the course content display unit 72 also displays the selected washing / drying course content. On the other hand, when the operation dial 90 is turned counterclockwise, the contents of the washing course are selected in the reverse order. The selection of the washing / drying course content can also be performed by pressing the washing / drying mode key 52. In this case, each time the key is operated, the course rotates the operation dial 90 clockwise. Are selected in the same order.

  After the selection of the contents of the washing / drying course is completed, the operation of the washing machine 1 is started based on the contents of the selected washing / drying course by pressing the start / pause key 62. At that time, the backlight of the liquid crystal display panel 80 is turned on from white to blue, and the background color of the panel is changed to blue so that the user is informed that the washing machine 1 is in operation. .

  In order to select the drying mode from the initial state in which the washing mode is selected, first, the drying mode key 53 is pressed. Then, “drying” in the operation mode display unit 71 and “automatic” in the drying process content display unit 73 are displayed, and the drying key 57 is turned on to display that the drying process is executed. This indicates that the mode has been switched to the selection of the drying mode. At this time, in the liquid crystal display panel 80, the white backlight is turned on, and the background color of the panel is set to white.

  Every time the operation dial 90 is rotated by a predetermined angle in the clockwise direction from this state, the content of the drying course is “standard” → “careful” → “memory” → “blank” → “pollen” → “drying of the tank”. When the operation dial 90 is further rotated in the clockwise direction from “tan drying”, the setting returns to “standard”. At that time, the course content display unit 72 also displays the selected dry course content. On the other hand, when the operation dial 90 is turned counterclockwise, the contents of the washing course are selected in the reverse order. The drying course content can also be selected by pressing the drying mode key 53. In this case, the course is operated in the same order as when the course rotates the operation dial 90 clockwise each time the key operation is performed. Selected.

  Then, after the selection of the washing / drying course content is completed, the operation of the washing machine 1 is started based on the selected washing course content by pressing the start / pause key 62. At that time, the backlight of the liquid crystal display panel 80 is turned on from white to blue, and the background color of the panel is changed to blue so that the user is informed that the washing machine 1 is in operation. .

  The washing mode, the washing / drying mode, and the drying mode can be switched at any time during the mode selection.

  Next, in order to perform the manual course operation from the washing mode, first, “ON” of the power key 60 is pressed, and a desired washing course content is selected by the dial operation 90 or the washing mode key 51.

  Then, when setting the washing time of the washing process, the washing key 54 is pressed. When the washing key 54 is operated, the washing process is selected, the indication of the washing key 54 is turned on, and the indications of the rinsing key 55 and the dehydration key 56 are turned off. When the operation of the washing machine 1 is started in this state, the washing time is automatically set based on the previously selected washing course content and the weight of the laundry. Subsequently, when the operation dial 90 is rotated by a predetermined angle in the clockwise direction, the currently set washing time is displayed on the number display portion 74, and the currently set washing time is known. The initial value of the washing time initially displayed on the number display unit 74 by the turning operation of the operation dial 90 differs depending on the selected washing course content. For example, as shown in FIG. When “standard”, “soft finish”, and “small amount” are selected as the contents, the initial value is 14 minutes.

  Thereafter, each time the operation dial 90 is rotated by a predetermined angle in the clockwise direction, the washing time increases by 1 minute. When the operation dial 90 is operated at the maximum setting time (for example, 30 minutes), The washing key 54 disappears without the washing process. When the operation dial 90 is operated from this state, the washing process for automatically setting the washing time is selected and the washing key 54 is displayed again. When the operation dial 90 is further operated, the minimum setting time (for example, 5 minutes) is displayed on the number display unit 74, and then the washing time is increased by 1 minute to the initial value, and thereafter, each setting content is repeated.

  The maximum set time and the minimum set time vary depending on the selected laundry course content. When the operation dial 90 is rotated by a predetermined angle in the counterclockwise direction, each time the operation dial 90 is operated, the washing time is set in the reverse order. The washing time can also be set by operating the washing key 54. In that case, each time the key is operated, the washing time is selected in the same order as when the dial is rotated clockwise.

  In the state where the above-described washing course contents are selected, the rinsing key 55 is pressed when setting the number of times of rinsing in the rinsing process. When the rinsing key 55 is operated, the rinsing process is selected, the display of the rinsing key 55 is lit, and the washing key 54 and the dewatering key 56 are turned off. When the operation of the washing machine 1 is started in this state, the number of times of rinsing is automatically set according to the previously selected laundry course content and the weight of the laundry. Subsequently, when the operation dial 90 is rotated by a predetermined angle in the clockwise direction, the number of rinses currently set is displayed on the number display portion 74, and the number of rinses currently set can be known. The initial value of the number of times of rinsing that is initially displayed on the number display unit 74 by the turning operation of the operation dial 90 varies depending on the selected washing course content. For example, as shown in FIG. When “Standard”, “Hot Mist”, “Speech”, and “Blanket” are selected as the contents, the initial value is twice.

  Thereafter, each time the operation dial 90 is rotated by a predetermined angle in the clockwise direction, the number of times of rinsing increases by one, and when the operation dial 90 is operated at the maximum set number of times (for example, four times), The rinse key 55 disappears without the rinse process. In this state, when the operation dial 90 is further operated in the clockwise direction, the rinsing process for automatically setting the number of times of rinsing is selected, and the rinsing key 55 is displayed again. When the operation dial 90 is further operated, the minimum set number of times (for example, once) is displayed on the number display unit 74, and then the number of times of rinsing is incremented by one up to the initial value, and thereafter, each setting content is repeated.

  The maximum set number and the minimum set number vary depending on the selected laundry course content. When the operation dial 90 is rotated by a predetermined angle in the counterclockwise direction, the number of times of rinsing is set in the reverse order to the above each time it is operated. The number of times of rinsing can also be set by operating the rinsing key 55. In that case, each time the key is operated, the number of times of rinsing is set in the same order as when the dial is rotated clockwise.

  In addition, in the state where the washing course content is selected, the dehydration key 56 is pressed to set the dehydration time for the dehydration process. When the dehydration key 56 is operated, the dehydration process is selected, the display of the dehydration key 56 is lit, and the display of the wash key 54 and the rinse key 55 is turned off. When the operation of the washing machine 1 is started in this state, the dehydration time is automatically set according to the previously selected laundry course content and the weight of the laundry. Subsequently, when the operation dial 90 is rotated by a predetermined angle in the clockwise direction, the currently set dehydration time is displayed on the numerical display 74, and the currently set dehydration time can be known. The initial value of the dehydration time that is initially displayed on the numeric display unit 74 by the turning operation of the operation dial 90 differs depending on the selected course, and for example, as shown in FIG. When “Standard”, “Hot Mist”, “Speedy”, and “Blanket” are selected, the initial value is 4 minutes.

  Thereafter, every time the operation dial 90 is rotated in a clockwise direction by a predetermined angle, the dehydration time increases by 1 minute. When the operation dial 90 is operated at the maximum set time (for example, 9 minutes), The display 16 of the dewatering key 56 disappears without performing the dewatering process. If the operation dial 90 is further operated clockwise in this state, a dehydration process for automatically setting the dehydration time is selected, and the display of the dehydration key 56 is turned on again. When the operation dial 90 is further operated, the minimum setting time (for example, 1 minute) is displayed on the number display unit 74, and then the dehydration time is increased by 1 minute until the initial value is reached. Thereafter, the setting contents are repeated.

  The maximum set time and the minimum set time vary depending on the selected laundry course content. When the operation dial 90 is rotated by a predetermined angle in the counterclockwise direction, each time the operation dial 90 is operated, the dehydration time is set in the reverse order. The dehydration time can also be set by operating the dehydration key 56. In that case, each time the key is operated, the dehydration time is set in the same order as when the dial is rotated clockwise.

  In addition, depending on the content of the selected washing course, it may be provided so that the predetermined process cannot be eliminated. For example, “hot mist” is provided so that the washing process cannot be eliminated, and “soft finish” is provided. You may provide so that a dehydration process cannot be eliminated. In such a case, it is not possible to eliminate the process, and the setting of the time and the number of times is the same as described above.

  Furthermore, the above is a description of the case where each stroke is set independently. However, when the washing stroke, the rinsing stroke, and the dewatering stroke are desired to be set in combination, the above operations may be performed sequentially (the setting order is It may be freely configurable). As a result, the contents of the set process remain lit as they are, so that the combination result of the desired process can be finally confirmed.

  Next, a case where the manual course operation is performed from the washing / drying mode will be described. In this case, first, “ON” of the power key 60 is pressed, and a desired washing / drying course content is selected by the dial operation 90 or the washing / drying mode key 52.

  The setting method of the washing time and the number of times of rinsing from this state is basically the same as in the above-described washing mode, but when the washing key 54 or the rinsing key 55 is operated, there is no process other than the set process. Never become. That is, even if the washing key 54 is operated, the rinsing process is not lost, and even if the rinsing key 55 is operated, the washing process is not lost. In many cases, the washing mode is used when the washing process or the rinsing process is performed alone, and in this case, there is no process other than the selected process. On the other hand, in the case of the washing / drying mode, it is considered that it was intended to be performed until the last drying process at the time of selecting this, that is, most of the processes are performed through the entire process. The display of the process is also left.

  When setting the content of the drying process, the user presses the drying key 57 in a state where a desired washing / drying mode is selected. When the drying key 57 is operated, for example, when “standard”, “hot mist”, and “memory” are selected as the contents of the washing / drying course, the contents of the washing / drying process are set from “automatic” to “quality finish” The drying process content display unit 73 is switched from “automatic” to “quality finish”. Subsequently, when the operation dial 90 is rotated by a predetermined angle in the clockwise direction, the content of the drying process is selected in the order of “quality finish” → “iron” → “reducing shrinkage”, and the operation dial 90 is further rotated in the clockwise direction. When the rotary operation is performed, the drying time increases from “10 minutes” to “90 minutes” every 10 minutes, and then the content of the drying process returns to “automatic”, and thereafter, each setting content is repeated. (See FIG. 5). At that time, the display of the drying process content display unit 73 is also switched to the display corresponding to the selected drying process content.

  In addition, when the operation dial 90 is rotated by a predetermined angle in the counterclockwise direction, the contents of the drying process are selected in the reverse order to the above each time the operation dial 90 is operated. Selection of the content of the drying process can also be performed by operating the drying key 57. In that case, each time the key is operated, the drying content is selected in the same order as when the dial is rotated clockwise.

  When manual course operation is performed from the washing / drying mode, it is set so that the dehydration time of the dewatering process cannot be selected, and the setting for eliminating the drying process cannot be performed. The selection of the dehydration process is prohibited because it is indispensable to perform the previous dehydration process in order to shorten the time required for the drying process. Further, in the washing / drying mode, when it is desired to set each process in combination, the above-described operations may be executed sequentially as in the washing course.

  Next, a case where the manual course operation is performed from the drying mode will be described. Since only the drying process is performed in the drying mode, each process cannot be selected and set even if the washing key 54, the rinsing key 55, and the dewatering key 56 are operated. About the setting method of the content of a drying process, since it is the same as that of the case where the content of a drying process is set in washing drying mode, it omits. The selectable drying process contents may be different from that in the washing / drying mode.

  Next, a setting method for bath water setting will be described. When the bath water key 59 is operated, “wash” in the bath water setting display section 76 is displayed, and the bath water setting content is set such that the bath water is used for water supply in the washing process. Subsequently, when the operation dial 90 is rotated by a predetermined angle in the clockwise direction, “rinse 1” is displayed in addition to “washing” on the bath water setting display section 76, and in addition to the washing process, the first rinsing is performed. It is set to the bath water setting content of using bath water for water supply. When the operation dial 90 is further operated, the display of the 1 bath water setting display section 76 is all turned off and the bath water setting content is set such that the bath water is not used. Thereafter, each setting content is repeated. When the dial is rotated in the counterclockwise direction, each time the dial is operated, the water setting content is selected in the reverse order.

  The selection of the bath water setting content can also be performed by operating the bath water key 59. In that case, every time a key operation is performed, the set water content is selected in the same order as when the operation dial 90 is rotated in the clockwise direction. In the setting of the bath water, the bath water washing cannot be set unless there is a washing process, and the bath water rinse cannot be set unless the number of rinses is two times or more. In that case, when the operation dial 90 is operated or a key operation is performed, the setting contents that cannot be set are skipped and the next setting contents are selected.

  Next, setting of timer reservation will be described. First, a desired operation mode is selected by the above-described method, and after selecting a desired course content, the reservation key 58 is pressed. When the reservation key 7 is operated, the current time is displayed on the number display portion 74, and “reservation time” is displayed on the display content display portion 75. As for the time displayed on the number display section 74, if the reservation setting has not been made in the past, the current time is displayed. If the reservation setting has been made in the past, the set time at that time is displayed. This set time represents the time when the operation ends. The set time is stored in the memory 112 whenever the reservation is set. In this state, when the operation dial 90 is rotated by a predetermined angle in the clockwise direction, the reservation time advances in units of 10 minutes each time the operation dial 90 is operated. If the one-digit digit is 1 to 9, the time advances in increments of 10 minutes after the carry. If the dial operation is performed at 23:50, the reserved time becomes 0:00, and thereafter, each setting content is repeated. When the operation dial 90 is rotated in the counterclockwise direction, the time is set in the reverse order to that described above each time the operation dial 90 is operated. The reservation time can also be set by operating the reservation key 58. In that case, each time the key is operated, the reservation time is set in the same order as when the dial is rotated clockwise.

  The current time is set by, for example, performing a specific key operation such as pressing the “ON” of the power key 60 while pressing the reservation key 58 to turn on the washing machine 1. The mode can be set. At this time, the time before setting is flashed on the number display portion 74, and “time” is displayed on the display content display portion 75. In this state, when the operation dial 90 is rotated clockwise by a predetermined angle, the time advances by 1 minute each time the operation dial 90 is operated. When the operation dial 90 is rotated by a predetermined angle in the counterclockwise direction, the time is delayed by one minute each time it is operated. The current time can be set by key operation. In this case, moving forward by 1 minute and delaying by 1 minute are performed by operating different keys. For example, when the reservation key is operated, the time advances by 1 minute, and when the bath key is operated, the time is delayed by 1 minute. After the operation dial 90 or a predetermined key is operated to set a desired time, when the start / pause key 62 is operated, the displayed time is set as the current time.

  In the present embodiment, the operation dial 90 is operated in both the clockwise direction and the counterclockwise direction. However, the operation dial 90 can be operated only in the clockwise direction or counterclockwise by a specific key operation. It is also possible to set so that it works only in one direction only in the turning direction, or does not accept the operation itself.

  In addition, when the operation dial 90 is rotated in the initial state after the power is turned on by operating the “ON” of the power key 60, the setting item selected can be set to an item other than the washing course. For example, when driving with the washing / drying mode selected, if the power-on key is operated again after the power is turned off after the operation is completed, “standard” of the washing / drying course is selected in the initial state. When the dial is turned in this state, the contents of the washing / drying course are selected. On the other hand, when the washing machine / drying mode is selected and the washing mode is selected and the driving is performed, the power is turned off after the driving is finished and the power key 60 is turned on again. The “standard” washing mode is selected. When the dial is turned in this state, the contents of the washing course are selected. In addition, any of the items such as the washing time, the number of times of rinsing, the dehydration time, and the content of drying can be set when the operation dial 90 is rotated in the initial state.

  The operation dial 90 is provided so as to obtain a feeling of movement whenever it is operated by a certain angle, and the contents of each item are basically switched every time this angle is operated. This angle can be changed by a specific key operation. By doing so, even if the dial is turned many times, items can be switched only a little, and an operation suitable for the sensitivity of the user can be performed.

  During operation of the operation panel 50, the backlight of the liquid crystal display panel 80 is white and the background color of the panel is white, so that characters displayed on the liquid crystal display panel 80 are easy to see. Operability can be improved. On the other hand, while the washing machine 1 is in operation, the backlight of the liquid crystal display panel 80 is switched from white to blue so that the background color of the panel is blue, thereby informing the user that the washing machine 1 is in operation. Can do.

  As described above, in the washing machine of the present invention, the setting content can be selected from the setting items not only by the rotation operation of the operation dial 90 but also by various key operations. When a small number of switchovers are required, each operation key can be operated so that the number of pressing operations of the operation key is not increased, and the selection operation is difficult due to the small rotation angle of the operation dial. By properly using either the operation key or the operation dial according to the setting item, the operability when selecting a predetermined setting content from a plurality of setting contents of the setting item should be accurate and quick. Can do.
