The operation unit 400 and the display unit 500 constitute the operation panel 22. The display unit 500 is a display unit that displays various types of information such as display of setting contents of the washing machine 10 and display of an operation status of the washing machine 10 during operation. The operation unit 400 is an operation unit that performs operations such as selection of a driving course, and the setting content is displayed on the display unit 500.

  FIG. 3 is a view showing an outline of the operation panel 22 of the washing machine 10 according to the first embodiment. Hereinafter, regarding the display on each display unit, “lighting” simply includes “flashing”. The operation panel 22 includes a display unit 500 and an operation unit 400. The operation panel 22 may have a configuration in which a transparent electrode film and an LED lamp as a light source are combined inside the display panel 22 so that the operation unit is recognized when characters of the display panel 22 shine by transmitted light. it can. In the present embodiment, the operation panel 22 will be described as this configuration.

  The operation unit 400 is an operation button, an operation unit 420 (driving operation operation unit, driving course display unit) for selecting a driving course, an operating unit 430 for starting / pausing, and a process for setting details of each process of the driving course. The display unit 440 includes a power-off button 410 (power-off operation unit) and a power-on button 412. The process display unit 440 includes, for example, a washing button 441, a rinsing button 442, a dehydrating button 443, a drying button 444, a bathing water button 445, a reservation button 446, and a water level button 447 (water level setting unit). The power on button 412 is a button for turning on the power of the washing machine 10, and the power off button 410 is a button for turning off the power of the washing machine 10.

  The operation units 400, 420, and 430 and the process display unit 440 serve both as an operation unit and a display unit. The operation units 400, 420, and 430 and the process display unit 440 are operation units that can be operated by pressing them. It is also a display unit that displays that the device is operating or operating. The operation unit 400 and the operation unit 420, the operation unit 430, and the process display unit 440 included in the operation unit 400 can turn on or off the display for each frame in addition to displaying characters on the display unit. The display unit 500 includes a display unit 501 that displays settings and operating conditions in the selected driving course, and a display unit 502 that displays setting contents and remaining time of each process.

  The washing machine 10 can arbitrarily set the time of the washing process, the number of rinsing processes, the time of the dehydration process, and the like. These settings are input to each operation unit of the process display unit 440 of the operation panel 22. Is done. In addition, the washing machine 10 includes an operation course corresponding to various purposes such as the type of clothes to be washed and the degree of washing.

  The operation panel 22 includes an operation unit 420 that selects a driving course. The operation unit 420 includes a washing button 421, a washing / drying button 422, and a drying button 423. There are various washing courses selected by the washing button 421, such as a standard course that is a standard driving course, a rough course that is suitable for washing heavily-washed laundry, and a careful course for washing clothes carefully. Course can be selected. A desired course can be selected by switching the display in order each time the washing button 421 is pressed.

  By pressing the operation unit 420 (421 to 423), it is possible to set and change the operation courses of washing, washing and drying. Which driving course is selected by the operation unit 420 is displayed on the display unit 501, and any one of the selected washing button 421, washing button 422, and drying button 423 is lit during driving. .

  Further, in the set driving course, the course contents can be set in more detail. For example, the washing process time can be set in the range of 5 to 30 minutes by operating the washing button 441, and the number of rinsing processes can be set in the range of 0 to 4 times by operating the rinsing button 442. It is configured.

  The dehydration process can be set in the range of 0 to 9 minutes by operating the dehydration button 443, and the drying process can be selected by selecting the drying course such as automatic drying, rushing, etc. and the process time by operating the drying button 444. It is configured to be settable. Further, the use of bath water can be set by the bath water button 445, and the reservation can be set by the reservation button 446. The water level button 447 is an operation unit that adjusts the water level in the washing and rinsing process. The display example of FIG. 3 shows a display example in which the washing course is selected and the washing process = 30 minutes, the rinsing process = 4 times, and the dehydration process = 9 minutes.

  Further, during the operation of the washing machine 10, the display unit 502 displays the remaining time of the washing process, the remaining number of times of the rinsing process, and the remaining time of the dehydration process. The time required for a certain stroke differs depending on each setting content and driving course, and the remaining time is sequentially subtracted and displayed as the stroke progresses. In addition, in the stroke display unit 440, the stroke that is currently in progress is lit and displayed so that it is possible to determine which stroke is currently being driven, for example, whether it is a washing stroke or a dehydration stroke. It is configured as follows. For example, if the washing process is being performed, the washing display 441 is lit, if the rinsing process is performed, the rinsing display 442 is displayed, if the dehydration process is being performed, the dehydration display 443 is displayed, and if the drying process is being performed, the drying display 444 is lit.

  After starting the operation of the laundry course, only the display of the selected laundry course (washing button 421) is lit on the display of the operation unit 420, so that it is possible to recognize what the driving course is being operated. In the display of the process display unit 440, only the process that is currently in progress is turned on and the process that has been completed is turned off. By doing so, it becomes possible to recognize the operating status of the washing machine 10, that is, which driving course is selected, which stroke is in progress, and which stroke remains.

  The display panel 22 is printed with a preset pattern, and a display substrate (not shown) for changing display specifications is attached to the inside of the display panel 22. An LED lamp (not shown) is disposed on the display substrate. For example, when a standard course is displayed as a washing course, an LED lamp arranged under the standard course letter is turned on, and other courses are turned off. By doing so, only the standard course part is lit, and it can be recognized that the standard course is selected. When the washing course is changed, a desired driving course is selected by sequentially turning on the LED lamps arranged under the characters indicating other driving courses. When the operation panel 22 is configured by combining an LED lamp, a transparent electrode film, and the like, the power consumption increases. Therefore, the unnecessary power reduction effect is increased by turning off the display that is no longer necessary.

  In this embodiment, in order to reduce waste of electric power, after a predetermined period of time has elapsed from the start of operation, after the predetermined timing has elapsed, the unnecessary display on the operation panel 22 is turned off, and the first display described below is displayed. Transition. In the first display, for example, as shown in FIG. 4, the washing button 441 of the process display unit 440 blinks, and the other rinse button 442, dehydration button 443, dry button 444, bath water button 445, reservation button 446, The water level button 447 is turned off. In the operation of the washing / drying course, the flashing display shifts to the washing button 441, the rinsing button 442, the dehydrating button 443, and the drying button 444 as the steps of washing, rinsing, dehydration, and drying proceed. Other buttons that are not flashing are turned off.

  In the first display, the remaining time is displayed on the remaining time display portion 502a. In the operation unit 400, the operation unit 430, the power-off button 410, and the power-on button 412 are lit and the washing / drying button 422 is blinking. Since the washing button 441 and the washing button 422 are displayed in a blinking manner, it can be recognized that the currently selected course is the “washing course” and the process currently being performed is the “washing process”. Further, since the remaining time is displayed in the remaining time display section 502a, the remaining time of the entire process can be recognized. In addition, since the buttons of the operation unit 430, the power-off button 410, and the power-on button 412 are lit, a predetermined operation assigned to them can be performed.

  In many cases, the user leaves the washing machine 10 after a while after starting the washing. Therefore, in such a case, even if the display on the operation panel 22 is fully lit, power is wasted. Therefore, in the first embodiment, after a predetermined period has elapsed after the laundry is started, the unnecessary display is set to the first display as shown below.

  The predetermined period can be a period in which the operation of the washing machine 10 can be changed. The predetermined period can be, for example, a period (timing) in which additional laundry can be input, and can be, for example, a period until the end of the washing process. Since the washing water containing the detergent remains from the start of the washing process to the start of drainage after the washing is completed, it is possible to allow additional addition of laundry. Accordingly, there is a case where display of the stroke display unit 440 of the operation panel 22 is necessary until then. Here, when additional laundry is added, settings such as further extending the washing time may be performed. During the washing process, the contents of the washing process may be changed by the washing button 441, the water level may be changed by the water level button 447, or the dehydration time may be changed. For this reason, the buttons (441 to 447) of the process display unit 440 are turned on until the washing process ends, and after the washing process is finished, the buttons are turned off because they are no longer necessary.

  The predetermined period may be, for example, 5 minutes before the end of the washing process, that is, 5 minutes before the start of drainage. During this period (timing), it is possible to add additional laundry, and until the end of most of the washing process, such as 5 minutes before the start of drainage, add additional laundry until the time is extended. Suitable when you don't want to do it.

  Further, the predetermined period may be a period until the display of the detergent input after the weight measurement of the laundry is finished. During this period, since the user is working in front of the washing machine 10 to put in the detergent, it is convenient to keep the display on the operation panel 22 on. As described above, in the present embodiment, the predetermined period can be a period in which the operation of the washing machine 10 can be changed.

  Since the operation unit 430 may temporarily stop the washing machine 10, the operation unit 430 continues to be lit even after a predetermined period has elapsed. Further, since it is desirable that the power-off button 410 and the power-on button 412 are lit for safety reasons, these buttons also remain lit.

  After the elapse of the predetermined period, the display on the operation panel 22 shifts to the first display. In the first display, most of the displays are turned off. Therefore, in preparation for the case where the user wants to restart the operation of the washing machine 10 for some reason, the control panel 22 is controlled to be fully lit by an input to any of the operation units 400 of the operation panel 22. When the user touches any operation unit 400 on the operation panel 22, an input signal is transmitted from the operation unit 400 to the control device 30. Upon receiving this reception, the control device 30 performs control to turn on the display unit 500 of the operation panel 22. Further, for example, the entire surface of the operation panel 22 may be set as a sensing unit of the touch sensor, and the above-described control may be performed when any portion of the operation panel 22 is touched.

  Alternatively, it may be possible to detect that the user has approached the vicinity of the washing machine 10 by the human sensor 44 and thereby control the entire operation panel 22 to be lit. In this case, when the user approaches the washing machine 10 and the human sensor 44 detects this, the human sensor 44 transmits a detection signal to the control device 30. Upon receiving this reception, the control device 30 performs control to turn on the display unit 500 of the operation panel 22. The human sensor 44 may be installed separately from the washing machine 10, for example, at the entrance of a washroom. Such a configuration is convenient when it is desired to check the situation of the washing machine 10 from a slightly distant place, and contributes to an improvement in convenience. Further, the same control may be performed by an opening / closing signal of the door 16 detected by the door sensor 38.

  Further, for example, five minutes before the end of the operation of the washing machine 10, control may be performed to turn on the display that was turned off in the first state. When the user is about to finish the laundry, the user is concerned whether or not the operation of the washing machine 10 has ended. Therefore, as described above, all items on the operation panel 22 are turned on 5 minutes before the end of the entire process. This is convenient because the user can recognize that the remaining time is about 5 minutes even from a slightly distant place. Also, this time can be freely set by the user. For example, it can be arbitrarily set to say 5 minutes before, 10 minutes before and 15 minutes before the end of washing, or every minute. Accordingly, the user can set the time according to his / her preference, which contributes to improvement in convenience.

  With this configuration, wasteful power consumption during operation of the washing machine 10 can be reduced, and energy saving performance can be improved. In addition, while providing necessary information to the user during a necessary period, it is possible to reduce wasteful power without losing convenience.

  After a predetermined period of time has elapsed, for example, even after the transition to the dehydration process, there are cases where it is desired to add additional laundry or to change other settings. In this case, as a matter of course, it is possible to start from the point of setting again from the beginning after the operation unit 430, the power-off button 410, etc. are pressed to temporarily stop the operation of the washing machine 10, as usual.

  In addition, for example, there is a case where it is desired to set a child lock setting if necessary even after a predetermined period has elapsed. For example, if the child lock is set to be executed by simultaneously pressing the water level button 447 and the operation unit 430, the water level button 447 and the operation unit 430 function as a child lock release operation unit in this case. Take on. However, if the setting is such that the water level button 447 and the operation unit 430 are turned off after the predetermined period has elapsed, the child lock is set and the washing is started. After the predetermined period has elapsed, the water level button 447 and the operation unit 430 are operated. 430 is turned off. Here, when it is desired to release the child lock, the display is turned on again from the extinguished state, and then the child lock release operation is performed, which is inconvenient. Therefore, as described above, for example, like a child lock, it is set at the start of operation of the washing machine 10, and the water level button 447 and the operation unit 430 are continuously lit even after a predetermined period of time has elapsed since the start of washing. Further, in this case, after the child lock is released, the normal display is performed, and when the predetermined period has elapsed, the operation panel 22 is the first display.

  In this way, even after a predetermined period has elapsed, for example, child lock can be easily released, improving user convenience, and after performing necessary operations Since it is the first display, it is possible to reduce useless power.

  In addition, as the operation panel 22, not only the above-mentioned structure but a liquid crystal panel having a touch sensor function may be used, for example. Even when a liquid crystal panel is used to display the operation panel 22, power is used in the same manner as when an LED lamp is used. Therefore, unnecessary power is reduced by turning off the display that is no longer necessary. be able to.

(Second Embodiment)
Next, a second embodiment will be described. The same elements as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the second embodiment, the user can arbitrarily arbitrarily set up to which timing of which process as a predetermined period. In the second embodiment, for example, the user can freely set, for example, at the end of the washing process, before draining before the washing process, before starting rinsing, and before the dehydrating process. The predetermined period may be a preset time, for example, 5 minutes after the start of operation, or the user may freely set the predetermined period. For example, a predetermined period may be set in the initial setting at the time of power-on when the washing machine 10 is purchased.

  Hereinafter, an example of a procedure when the user sets a predetermined period for each item will be described. FIG. 5 is a display example of the operation panel 22 in this case. The setting described below is assumed to be set when the washing machine is purchased in the war record or when the washing machine is returned to the state at the time of shipment and is turned on for the first time.

  When you turn on the main unit for the first time after purchasing a new washing machine and installing the main unit, or when you turn on the main unit for the first time after resetting the setting of the washing machine and returning to the factory default state, The display 22 is automatically set to each setting mode. The user can operate and make settings in accordance with an instruction manual or the like.

  FIG. 5 shows a display example of the operation panel 22 in the setting mode after the power is turned on. On the operation panel 22, “SEt1” (set 1) indicating the first screen of the setting display is displayed on the remaining time display portion 502a for displaying the remaining time. “1”, “0”, and “0” are respectively displayed on the washing time display portion 502b, the rinse count display portion 502c, and the dehydration time display portion 502d. Here, “1” is a setting content that the lighting display is ON after a predetermined period has elapsed, and “0” is a setting content that the lighting display is OFF after a predetermined period has elapsed. The display units 502b, 502c, and 502d are set by pressing the washing button 441, the rinsing button 442, and the dehydrating button 443, respectively. Thereby, the process (timing) to turn off is set. For example, when “washing = 1”, the timing at the end of the washing process, when “rinsing = 1”, when the rinsing process ends, and when “dehydration = 1”, the timing at the end of the dehydration process A period is set.

  As described above, since the predetermined period can be arbitrarily set by the user, it can be matched to the user's usage, usage, and user's preference, which contributes to the improvement of convenience.

(Third embodiment)
Next, a third embodiment will be described. The same elements as those in the first and second embodiments are denoted by the same reference numerals, and description thereof is omitted. In the third embodiment, the user can freely set items to be displayed after a predetermined period has elapsed. An example of the setting procedure will be described below.

  On the operation panel 22, items to be displayed after a predetermined period have elapsed, when the washing machine 10 is newly purchased and the main body is turned on for the first time after the main body is installed, or the setting of the washing machine is reset and returned to the factory default state. When the power of the main body is turned on for the first time after that, the display automatically enters a preset setting mode. The user can operate and make settings in accordance with an instruction manual or the like. When the start / pause operation unit 430 is pressed after the setting in the second embodiment shown in FIG. 5 is completed, the remaining time display unit 502a for displaying the remaining time is displayed on the operation panel 22, as shown in FIG. “SEt2” (set 2) indicating the second surface of the setting display is displayed. As shown in FIG. 6, the setting contents are displayed on the washing time display section 502b, the rinse count display section 502c, and the dehydration time display section 502d. Here, “1” means display ON, and “0” means display OFF. By pressing each of the washing button 441, the rinsing button 442, and the dehydrating button 443, the setting items to be displayed on the 502b to 502d are set, and the display to be turned off is set. The washing time display unit 502b indicates ON / OFF of the remaining time display unit 502a, the rinse count display unit 502c indicates ON / OFF of the display unit 501 that displays the operation status, and the dehydration time display unit 502d displays the drying of the display unit 502. Mode ON / OFF is shown. Here, an example is shown in which “1”, “0”, and “0” are set, respectively, the remaining time display unit 502a is ON, the display unit 501 is OFF, and the drying mode is OFF. Subsequently, when the start / pause operation unit 430 is further pressed, as shown in FIG. 7, the operation panel 22 displays “SEt3” indicating the third screen of the setting display on the remaining time display unit 502a for displaying the remaining time. "(Set 3)" is displayed, and the process display and the driving course display are set. Here, the washing time display unit 502b indicates ON / OFF of the stroke display unit 440, and the rinse count display unit 502c indicates ON / OFF of the operation unit 420 indicating the operation course contents. Here, “3” is display ON, and “4” is display OFF. Since there are many setting items, it is possible to recognize which display ON / OFF is set by changing the setting numerical value while using the same display unit in this way. Here, the stroke display unit 440 is set to “3” and ON, and the operation unit 420 is set to “4” and OFF.

It is a point that is turned off. In the second display, the remaining time display portion 502a is lit. Since the process display unit 440 and the washing / drying button 422 are turned off, the currently selected driving course and the currently performed process cannot be recognized, but the remaining time display unit 502a is displayed, so the entire process is performed. Remaining time can be recognized. If the user thinks that it is enough to grasp the remaining time, the remaining time display unit 502a may be displayed, and other displays may be turned off. Therefore, this is displayed in the third display. In the third display, since the display is further reduced compared to the first display, it can contribute to further power reduction.

  However, the operation unit 430 is lighted for safety reasons such as an emergency stop. Further, the power-off button 410, the power-on button 412, and the display switching button 450 are lit because they may be used. The same applies to third to fifth displays described later.

  Next, when the display switching button 450 is further pressed, the third display shown in FIG. 9 is switched to the fourth display shown in FIG. The fourth display is different from the second display in that the remaining time display unit 502a and the operation unit 420 that displays the selected driving course are turned off. That is, in the fourth display, instead of this, the process currently being performed in the process display unit 440 (in FIG. 10, the washing button 441) is lit. In the fourth display, the remaining time cannot be recognized because the remaining time display portion 502a is not displayed. However, the stroke display portion 440 is lit and displayed in accordance with the progress of the stroke, so that the currently performed stroke is recognized. can do. If the user thinks that the remaining time display unit 502a is unnecessary and that it is sufficient to recognize the current progress, the process display unit 440 is displayed and the remaining time display unit 502a is turned off. It does not matter. Therefore, this is displayed in the fourth display. In the fourth display, since the display is further reduced compared to the first display, it can contribute to further power reduction.

  Next, when the display switching button 450 is further pressed, the fourth display shown in FIG. 10 is switched to the fifth display shown in FIG. The fifth display is different from the second display in that the remaining time display portion 502a and the stroke display portion 440 are turned off in the fifth display. Here, the operation unit 420 that displays the currently selected driving course is lit. FIG. 11 shows an example in which the washing course is selected, and the washing button 422 is lit.

  In the fifth display, since the remaining time display unit 502a and the process display unit 440 are not displayed, the remaining time and the currently performed process cannot be recognized, but the operation of the currently selected driving course in the operation unit 420 is not performed. Since the part is lit up, it is possible to recognize the driving course currently being implemented. If the user does not need to display the remaining time display unit 502a and the process display unit 440 and only needs to be able to recognize the currently selected driving course, the currently selected operation unit 420 is selected. The operation part of the driving course that is present may be turned on, and the remaining time display part 502a and the process display part 440 may be turned off. Therefore, this is displayed in the fifth display. In the fifth display, since the display is further reduced compared to the first display, it can contribute to further power reduction.

  Next, when the display switching button 450 is further pressed, the fifth display shown in FIG. 11 is switched to the second display shown in FIG. Thereafter, each time the display switching button 450 is pressed, the second display, the third display, the fourth display, and the fifth display are sequentially switched, and this is repeated. When the desired display is obtained, the user may stop pressing the display switching button 450 further.

  With the configuration described above, the display setting of the operation panel 22 can be switched so that the display item that the user feels unnecessary is turned off during the operation of the washing machine 10. For this reason, since it can be set as the display which reduced useless display, it can be connected with energy saving. In addition, since it can be set while actually displaying the content, it is possible to set the display setting more suited to the user's preference and usage.

  Note that when the display pattern is switched from the second display to the fifth display by pressing the display switching button 450 as described above, the control device 30 displays the last display pattern. Control to store in the storage device provided. In the next operation, the control device 30 calls the stored display pattern setting and performs control to display the display pattern.

  This eliminates the need to set a display pattern every time when the washing machine 10 is used, thereby eliminating the need for wasteful operations and preventing forgetting to set, thereby improving convenience. .
