Explanatory drawing which shows the relationship between a LED light-emitting body and a light-guide plate, FIG. 13 is the operation display part of the refrigerator It is a cross-sectional view of the kick light guide plate.

  In FIG. 1, the refrigerator main body 1 is formed by filling and foaming urethane or the like between a metal outer box opened to the front and a hard resin inner box. The refrigerator main body 1 has storage chambers 5 to 9 therein. The storage chambers 5 to 9 are located in the lower part of the refrigerating room 5, the switching room 6 located below the refrigerating room 5, the ice making room 7 arranged in parallel with the switching room 6, the switching room 6 and the ice making room 7. The freezer compartment 8 is a vegetable compartment 9 located below the freezer compartment 8.

  Further, the front surface of the refrigerator compartment 5 is opened and closed freely by, for example, double doors 10 and 10, and the front portions of the switching chamber 6, the ice making chamber 7, the freezer compartment 8 and the vegetable compartment 9 are drawn out doors 11 and 10. 12, 13, and 14 are freely opened and closed, and each of the doors 10 to 14 is a heat insulating door having a foam heat insulating material 15 (see FIG. 3) filled and foamed with hard urethane or the like like the refrigerator main body 1. ing.

  Here, among the doors 10 to 14, the right door 10 of the double door type door is provided with an operation display unit 16, and the configuration thereof will be described below.

  2 to 13, reference numeral 17 denotes a substrate storage portion provided on the front surface of the door 10 so as to form a recess from the front surface of the door 10 toward the foamed heat insulating material 15, and above and below the long side end portion of the door 10. Is provided. Reference numeral 18 denotes a substrate holding unit installed in the substrate storage unit 17, as is clear from FIGS. 4, 5, 7, etc. It is attached.

  Reference numeral 21 denotes an electrostatic touch sensor incorporated in the substrate 19 for the operation unit. In this embodiment, three electrostatic touch sensors 21 for increasing and decreasing the cooling capacity and for menu / decision are incorporated.

Reference numeral 22 denotes a light guide plate that is superposed on each of the electrostatic touch sensors 21, and a LED light emitter 23 is provided on the substrate 19 so as to face one piece, in this embodiment, the upper side. The light guide plate 22 is positioned substantially on the same plane as the LED light emitter 23. As shown in FIGS. 12 and 13, one piece facing the LED light emitter 23 is provided with an arc-shaped recess 22a having a different curvature, which will be described later. A textured surface 22b is formed on the flat surface on the decorative plate side, and an inclined surface 22c is formed on the outer peripheral portion excluding the flat surface. When each of the electrostatic touch sensors 21 detects a touch operation, the LED light emitter 23 corresponding to the electrostatic touch sensor 21 is energized, and the light guide plate 22 shines with the light.

  Reference numeral 24 denotes a decorative plate attached to the substrate storage portion 17 so as to cover the front surfaces of the substrate holding portion 18 and the operation portion substrate 19, and is a portion facing the electrostatic touch sensor 21 and the light guide plate 22 superposed on the electrostatic touch sensor 21. For example, “∧”, “∨”, “menu determination” and the like are written as the operation unit 25. Further, as shown in FIGS. 10 and 11, a light guide plate housing recess 24a is formed on the inner surface portion of the operation unit 25, that is, the inner surface portion facing the light guide plate 22 of the upper and lower electrostatic touch sensors 21. In addition, the outer peripheral portion of the light guide plate housing recess 24a is inclined in correspondence with the inclined surface 22c of the light guide plate 22. This inclination makes it possible to install the light guide plate 22 without any gaps, and it is possible to prevent sink marks due to a sudden change in the thickness of the decorative plate 24, and the appearance of the operation unit 25 that also serves as a display unit on the outer surface of the decorative plate. It can be good.

  As shown in FIGS. 5 and 7 and the like, the substrate holding portion 18 for the operation portion is integrally formed with a substrate pressing portion 26 having elasticity, and urges the substrate 19 toward the decorative plate 24 side. Thus, each electrostatic touch sensor 21 on the substrate 19 and the light guide plate 22 placed on the electrostatic touch sensor 21 are pressed against the operation unit 25. In particular, in this embodiment, the substrate pressing part 26 is provided in correspondence with each electrostatic touch sensor 21 so that each electrostatic touch sensor 21 is individually pressed against the operation part 25 of the decorative plate 24. .

  Further, as shown in FIGS. 5, 7, etc., the substrate holding portion 18 is provided with substrate separation preventing stoppers 27 at portions corresponding to the upper and lower end portions of the substrate 19. By fitting the upper and lower end portions of the substrate 19, the substrate 19 is prevented from being detached from the substrate holding portion 18 by the elastic force of the substrate pressing portion 26. Since the thickness of the substrate removal prevention stopper 27 is smaller than the thickness of the light guide plate 22, the depth of the light guide plate housing recess 24a corresponding to the light guide plate 22 and the substrate separation prevention stopper 27 can be made the same. It has no aspect.

  In the above configuration, when the operation display unit 16 of the refrigerator touches the notation of the operation unit 25, the LED light emitter 23 emits light, the light guide plate 22 shines, and the display written on the operation unit 25 illuminates brightly. That is, the light guide plate 22 is irradiated with light from the LED light-emitting body 23 from one piece, shines brightly, and illuminates the display described on the operation unit 25.

  At this time, since the light guide plate 22 has an outer peripheral portion as an inclined surface 22c, the light irradiated into the light guide plate 22 is refracted into the light guide plate 22 by the inclined surface 22c and remains in the light guide plate 22. And more brightly than in the case where there is no inclined surface 22c. Accordingly, the notation of the operation unit 25 is brightened over a wide range, and the display quality is remarkably superior to that of the spot illuminated.

  In particular, since the light guide plate 22 has a textured surface 22b on the flat surface of the display unit other than the inclined surface 22c, the entire surface facing the operation unit 25 is irregularly reflected by the texture of the light incident on the light guide plate 22. Shine brightly. Therefore, the notation of the operation unit 25 is further brightly illuminated throughout the entire area.

Moreover, in this embodiment, since the circular arc-shaped recessed part with a different curvature is provided in the piece which receives the light irradiation from the said LED light-emitting body 23 of the said light-guide plate 22, the light of the LED light-emitting body 23 is utilized efficiently. Can shine brightly and evenly.

  That is, the broken line in FIG. 12 shows the light beam from the LED light emitter 23, and the light from the highly directional LED light emitter 23 spreads only about 20 to 30 degrees, but the light from the central portion is a broken line. As shown by A, the light is polarized in the left-right direction in the drawing by the arc-shaped concave portion having a small curvature at the center, and is dispersed throughout the light guide plate 22 to brighten it. On the other hand, the light from the outer peripheral portion of the LED light emitter 23 is polarized in the direction in which the spread in the left-right direction is suppressed as shown by the broken line b, and the useless light emitted outside the light guide plate 22 is reduced and guided. The amount of light that irradiates the light plate 22 increases. As a result, the light guide plate 22 uses the light from the LED light emitters 23 efficiently to shine brightly and uniformly. Therefore, even if the LED light emitter 23 is installed on one side of the light guide plate 22 and irradiated from the one side, the notation of the operation unit 25 can be easily seen with sufficient brightness.

  Further, by forming the arc-shaped concave portion 22a on a piece of the light guide plate 22 facing the LED light emitter 23, even if the light guide plate 22 and the LED light emitter 23 are disposed close to each other, due to the polarization action by the concave portion 22a. As described above, the entire light guide plate can be illuminated efficiently and uniformly. That is, it is possible to illuminate the light guide plate 22 and thus the entire display of the operation unit 25 brightly and uniformly while minimizing the size between the light guide plate 22 and the LED light emitter 23 and reducing the installation space.

  On the other hand, since the LED light emitter 23 is installed on one side of the light guide plate 22 as described above, the dimension in the depth direction from the operation unit 25 is only the thickness of the light guide plate 22. Compared with the case where the optical plates 22 are superposed, the dimension in the depth direction can be reduced, and the thickness of the foam heat insulating material 15 of the door can be increased accordingly. In particular, since the LED illuminant 23 has a strong directivity of light as described above, when it is superposed on the light guide plate 22, a certain distance from the light guide plate 22 is secured in order to brighten the entire planar area of the light guide plate 22. This is effective because the thickness of the foamed heat insulating material 15 is reduced accordingly. By increasing the thickness of the foam heat insulating material 15, the heat insulating effect can be enhanced, and energy saving can be promoted accordingly. In particular, in the case where the operation display unit 16 is provided on the door edge as in this embodiment, the foam heat insulating material 15 is used because the door edge is the place where the temperature rises most easily in the entire door. It is effective to be thick.

  Further, in this embodiment, the portion provided with the display configuration is an operation unit 25 provided with an electrostatic touch sensor 21. When the user touches the operation unit 25, the LED light emitter 23 emits light. The light guide plate 22 shines and the display displayed on the operation unit 25 is easily visually recognized. Therefore, smoke can be applied to the decorative plate 24 to make it difficult to see the notation of the operation unit 25 to improve the design, and it is also possible to prevent mischief and the like caused by the child visually observing the operation unit. . Moreover, even if the decorative plate 24 is smoked to improve the design and prevent mischief in this way, the display becomes visible once the operation unit 25 is touched, so that the operability is also good. can do.

  Further, since the electrostatic touch sensor 21 is always pressed against the operation unit 25 side of the decorative plate 24 by the substrate pressing unit 26, the electrostatic touch sensor 21, the light guide plate 22, and the operation unit 25 of the decorative plate 24 are not connected. It will always be in close contact with no gaps. Therefore, when the touch operation is performed on the operation unit 25 of the decorative plate 24, the electrostatic touch sensor 21 can detect this with high sensitivity via the light guide plate 22, and can eliminate or greatly reduce an input error.

  In addition, the portion facing the electrostatic touch sensor 21 is thinned by the light guide plate housing recess 24a provided on the decorative plate 24, and the sensitivity of the electrostatic touch sensor 21 can be further improved, such as an input error. There are few and it can be set as a reliable operation part.

  Further, since the substrate 19 provided with the electrostatic touch sensor 21 is held by the substrate holding portion 18 by the substrate removal prevention stopper 27, the substrate 19 provided with the electrostatic touch sensor 21 and the substrate holding portion 18 are not pressed by the substrate. The unit can be united against the resilience of the unit 26, and in the process of assembling the operation display unit, the substrate 19 provided with the electrostatic touch sensor 21 and the substrate holding unit 18 are separated and the assemblability is lowered. Can be prevented and productivity can be improved.

  Although not described in detail, the display configuration shown in this embodiment is applied to the notation of the operation unit 25, but it goes without saying that the display configuration can also be applied to a display-dedicated portion.

  As described above, the present invention is such that a light guide plate is arranged on the display unit, and the light of the LED light emitter can be irradiated from one side of the light guide plate to illuminate the display unit widely. However, the display device described in the above embodiment is the same as that of the device main body and the present embodiment. It can be provided in various things such as a door or a remote control.

  As described above, the present invention can achieve both improvement in display quality and reduction in power consumption, and can be widely applied to many devices such as general-purpose refrigerators, home appliances, office equipment, and electronic devices.
