  By operating the power-off button 73 disposed on the operation display panel unit 25, the washing machine can be turned off at any timing.

  FIG. 12 is a front view of the transparent electrode sensor of the touch panel operation display unit of the washing machine in the embodiment of the present invention, and FIG. 13 is a side view of the touch panel operation display unit of the washing machine.

  In FIG. 12, the transparent electrode sensor 33 forms a transparent electrode 95 by depositing and depositing highly conductive indium tin oxide called ITO on a glass substrate 65 and performing etching.

  Among the bright electrodes 95, the "water level" transparent electrode 85 is located at the position opposite to the "water level" enclosure display 75b of the liquid crystal panel, the "wash" transparent electrode 86 is located at the opposite position of the "wash" enclosure display 76b, and the "rinse" enclosure display 77b. "Rinse" transparent electrode 87 at the opposite position, "Dehydration" transparent electrode 88 at the opposite position of "Dehydration" enclosure display 78b, "Reservation" transparent electrode 89 at the opposite position of "Reservation" enclosure display 79b, and "Bath water" enclosure display "Bath water" transparent electrode 90 at the opposite position of 80b, Omakase course transparent electrode 91 at the relative position of the Omakase course enclosure display 81b, "Blanket" transparent electrode 92 at the opposite position of the "Blanket" enclosure display 82b, "My style" enclosure A “private” transparent electrode 93 is formed at a position opposite to the display 83b, and a “delicate” transparent electrode 94 is formed at a position opposite to the “delicate” enclosure display 84b. Although not shown, the transparent electrode 95 is electrically connected to the touch panel dedicated IC 40, and the touch panel dedicated IC 40 is electrically connected to the control means 39.

  In FIG. 13, a shield electrode 69 is formed on the back surface of the transparent electrode sensor 33 by depositing ITO on one surface. The shield electrode 69 is connected to the GND line of the main control board 36 through the FPC wiring 70 to improve power noise resistance. The touch panel operation display unit 38 is caused by switching noise from the liquid crystal panel 34 disposed below. Prevent malfunction.

  The transparent electrode sensor 33 is bonded and fixed to the transparent glass plate 31 with a transparent double-sided tape 37.

  The change in capacitance is determined by the dielectric constant of the substance touched by the finger. The larger the dielectric constant, the larger the change in capacitance and the higher the sensitivity. Note that high sensitivity means that the position pressed by the finger can be recognized accurately and quickly, for example, it is difficult to cause false detection that recognizes the attachment of water droplets as being touched by the finger, and false detection due to the effect of external noise. It is difficult to do.

  For example, the dielectric constant of glass is about 9, the dielectric constant of ABS resin or PET resin is about 3, and the change in capacitance is inversely proportional to the thickness, so if the material of the part touched by the finger is a glass plate, Even if the thickness is three times that of ABS resin or PET resin, the sensitivity can be equalized.

  In the present embodiment, the transparent electrode sensor is a glass substrate, but it goes without saying that a similar effect can be obtained even with a resin sheet such as PET.

  In this embodiment, the electrodes are wired only at the positions corresponding to the display portions of the liquid crystal panel so that only the positions corresponding to the display portions can be detected. Needless to say, the same performance can be obtained even if the configuration is such that the wiring can be detected by touching any part of the glass substrate.

  A detection mechanism during a touch operation will be described with reference to FIGS.

  The transparent electrode 95 formed on the transparent electrode sensor 33 has a very small electrostatic capacitance component (about 2 to 3 PF), and the voltage is constantly applied to the X electrode 66 from the touch panel dedicated IC 40 with a predetermined cycle. Is applied repeatedly. The Y electrode 67 constantly outputs a voltage applied from the X electrode 66 and passed through the electrostatic capacitance component, and returns a voltage signal to the touch panel dedicated IC 40, so that the Y electrode 67 always has the electrostatic capacitance component present in the touch panel operation display unit 38. Monitor voltage changes.

  When a person touches the transparent glass plate 31, the finger is electrically connected between the transparent glass plate 31, the transparent double-sided tape 37, and the transparent electrode sensor 33, and the electrostatic capacity component of the person (generally about 100 to 150 PF). ) Flows, and as a result, the voltage of the electrostatic capacitance component existing in the touch panel operation display unit 38 detected by the touch panel dedicated IC 40 is largely changed, so that the touch panel dedicated IC 40 confirms that the touch operation has been performed, and the confirmation signal Is transmitted to the control means 39.

  FIG. 14 is a diagram illustrating detection at the time of touch detection of the touch panel display unit of the operation display unit of the washing machine in the embodiment of the present invention, and FIG. 15 is at the time of touch detection of the touch panel display unit of the operation display unit of the washing machine. FIG.

  In FIG. 14, the X-axis direction indicates the long side of the transparent glass plate 31, the Z-axis direction indicates the short side of the transparent glass plate 31, and the Y-axis direction indicates touch sensitivity when a touch operation is performed. . FIG. 14 shows that the sensitivity increases when the touch operation is performed in the Y-axis direction. FIG. 14 shows data in which a touch signal detected by the touch panel dedicated IC 40 is confirmed on a personal computer (not shown). Generally, a threshold value S for determining a touch operation is set in the touch panel dedicated IC 40, and whether or not the touch operation is performed is determined by whether or not the height H of the touch signal exceeds the threshold value S.

  In FIG. 15, (a) shows an example of high sensitivity when water adheres to the transparent glass plate 31, and (b) shows an example of high sensitivity when the liquid detergent adheres to the transparent glass plate 31. (C) has shown the example of the sensitivity height when the transparent glass plate 31 touch operation is carried out with a finger | toe.

  From this example, water having low conductivity with respect to high sensitivity has a high sensitivity of the threshold value S or less, but a highly conductive liquid detergent has high sensitivity of the threshold value S or more and malfunctions due to erroneous detection. There is a fear.

  This problem can be solved by setting the threshold value S to be higher than the sensitivity level of the liquid detergent. However, if the threshold value S is set high, the responsiveness at the time of touch operation with a finger is deteriorated and the usability is poor. There is a possibility. (C) in FIG. 15 shows an example of the high touch sensitivity by the touch operation with the finger, but the area where the finger touches the transparent glass plate 31 directly affects the capacitance, so that the operation is performed. Changes in the height of touch sensitivity depending on the size of a person's finger and the instantaneous touch area when touched can also cause a decrease in responsiveness.

  As described above, in this embodiment, a mode such as a driving course and various functions can be selected, and the operation display panel unit 25 that performs display based on the input information and the operation display panel unit 25 are provided. A touch panel operation display unit 38 that accepts a touch operation instruction with a finger, a setting button unit 71 and a course selection button unit 74 that are provided on the touch panel operation display unit 38 and that can be operated by touch operation are provided. At the time of setting, only the buttons that can be touch-operated in the setting button section 71 and the course selection button section 74 are displayed with their button names, and an enclosure is displayed around the buttons to perform the operation. This makes it easy to distinguish between operation units that can be touch-operated and display units that contain only characters and symbols, improving operability. It is possible.

  Further, in the course selection button section 74 having a plurality of options, the selected button displays a selection pattern indicating that it has been selected above and below the button name displayed in the substantially central portion, and all the course selection buttons By configuring an enclosure indicating that the button is a touch-operable button around the unit 74, it is possible to reliably tell the user the selection content currently selected among a plurality of options, Further operability can be improved.

  In addition, when the operation start button 72 of the pressing operation button section 48 is pressed, only the button name is displayed for the buttons that cannot be touched among the set button section 71 and the course selection button section 74 that have been selected. The buttons that can be touch-operated are configured to display the button name and the button's surroundings so that the buttons that can be operated and cannot be operated can be clearly identified even after the start of operation. As a result, further operability can be improved.

  In the present embodiment, when the driving course is selected, the selected selection displays 81c to 84c are displayed. However, the selected selection displays 81c to 84c may be hidden, and the selected selection display is displayed. You may make it blink 81c-84c. When a liquid crystal panel capable of color display is used as the liquid crystal panel 34, the color of the selected display units 81 to 84 may be different from the color of the display units 81 to 84 that are not selected. In addition, as long as the display of the selected display units 81 to 84 is different from the other display units 81 to 84 that are not selected, other display methods may be adopted.

  Further, in the present embodiment, the enclosure displays 75b to 80b of the display units 75 to 80 that can be selected are displayed, but the displays 75a to 80a or the enclosure displays 75b to 80b are blinked. May be. When a liquid crystal panel capable of color display is used as the liquid crystal panel 34, the colors of the display portions 75 to 80 that can be selected may be different from the colors of the display portions 75 to 80 that cannot be selected. In addition, other display methods may be adopted as long as the display of the selectable display portions 75 to 80 is different from the display portions 75 to 80 that cannot be selected.

  As described above, the washing machine according to the present invention is displayed on the touch panel operation display unit of the operation display panel unit while facilitating the operation by adopting a touch panel system that can be operated by touching the operation display panel unit with a finger. By displaying characters and symbols in an easy-to-understand manner and easy to select, it becomes possible to improve operability, and thus can be applied to other electrical appliances having a touch panel display unit.
