The support 211 integrally includes a rectangular bottom wall 211a and four side walls (wall portions) 211b to 211e that rise from the four side ends of the bottom wall 211a.
The circuit board 212 is placed on the bottom wall 211a of the support 211 (see FIG. 7). On one surface of the circuit board 212, a plurality of LEDs 213 and a 7-segment LED display 214 are mounted as a light source group.

  The light reflecting member 215 includes a plurality of reflection holes 215 a corresponding to the arrangement of the LEDs 213 and a plurality of through holes 215 b corresponding to the arrangement of the 7-segment LED displays 214. The inner surfaces of the reflection hole 215a and the through hole 215b have light reflectivity, and reflect the light of the plurality of LEDs 213 and the 7-segment LED display 214 toward the panel cover 220 (see FIG. 3).

  The touch key film 216 is a transparent or translucent flexible substrate placed on the upper surface of the light reflecting member 215 facing the panel cover 220. The touch key film 216 includes a flat upper surface 216a, one front end 216b whose front side (front side) is bent downward, a rear end 216c opposite to the front end 216b, and a plurality of transparent windows. Part 216d. A rear end 216 c of the touch key film 216 serves as a boundary between the operation unit 230 and the display unit 250 of the operation panel 200.

  The touch key film 216 is provided with a detection electrode (not shown) for detecting a change in capacitance due to the operation of the touch keys 234 to 237. Each detection electrode is made of a transparent conductive film and has a one-to-one correspondence with the touch keys 234 to 237 (see FIG. 4) arrangement position of the operation panel 200. The detection electrode (not shown) is disposed directly above each reflection hole 215a of the light reflection member 215.

  The touch key film 216 is irradiated with light from the LED 213 and the 7-segment LED display 214 from the back through the reflection hole 215a and the through hole 215b of the light reflection member 215. The touch key film 216 transmits the light of the LED 213 that emits light in each operation mode through the transparent window 216d.

  The rib 221 is a standing wall that protrudes from the back surface 220b (see FIGS. 9 and 10) of the panel cover 220 toward the touch key film 216 side. The rib 221 is provided at the boundary between the touch key film 216 and the display unit 250. After assembling the operation panel 200, the rib 221 contacts the upper surface 216a of the touch key film 216, and is on the touch key film 216 (particularly, a detection electrode (not shown)) from the display unit 250 side (the upper side with the gradient). Side) to prevent water from entering.

  The groove portion 217 is provided along the outer edge of the rear end portion 216c of the touch key film 216. For example, the groove 217 may be formed on the upper surface of the light reflecting member 215, or may be formed of a member different from the light reflecting member 215. Furthermore, it may be formed on the upper surface 216a of the touch key film 216. The groove portion 217 is more reliably prevented from entering water from the display portion 250 side onto the touch key film 216 by engaging the tip portion of the rib 221 after the operation panel 200 is assembled.

  In addition, what is necessary is just to provide the rib 221, and the groove part 217 is not essential. However, by providing the groove portion 217 that engages with the rib 221, it is possible to more firmly prevent water from entering the touch key film 216 from the display portion 250 side.

<Panel cover 220>
FIG. 8 is a plan view of the panel cover 220 as viewed from above. FIG. 9 is a rear view of the panel cover 220 of FIG. 8 viewed from below by turning over without changing the left-right direction. FIG. 10 is a cross-sectional view taken along the line AA of FIG.
As shown in FIG. 8, the panel cover 220 is a cover that covers the upper portion of the panel body 210 (see FIGS. 5 to 7), and when assembled as the operation panel 200, the user touches or presses with a finger to operate the operating conditions. The display unit 250 has a function of displaying various setting conditions, setting time, and the like.
The panel cover 220 is made of, for example, PET (polyethylene terephthalate) resin, and at least a part of the operation unit 230 and the display unit 250 has translucency.

  As shown in FIGS. 8 to 10, the panel cover 220 includes an upper surface 220a (see FIG. 8), a back surface 220b (see FIG. 9) as a back surface, and an end portion 220c (see FIG. 10) curved downward on the front end side. ), An end 220d (see FIG. 10) combined with the upper end surface 115b (see FIG. 1) on the rear end side, and a drain hole 220e (see FIGS. 9 and 9) formed downward from the inner surface of the end 220c. 10) and a rib 221 (water intrusion prevention structure) (see FIGS. 9 and 10) that prevents water intrusion into the operation unit 230.

  The rib 221 is a standing wall that protrudes from the back surface 220 b of the panel cover 220 toward the touch key film 216. The rib 221 is formed to extend in the longitudinal direction of the boundary portion between the operation unit 230 and the display unit 250, and prevents water from entering the operation unit 230 (particularly, the touch keys 234 to 247 of the operation unit 230).

  When the panel cover 220 is attached to the panel main body 210, the rib 221 prevents water from entering from the display unit 250 side to the operation unit 230 side by the projecting end of the rib 221 coming into contact with the touch key film 216. Further, in the present embodiment, a part of the rib 221 is fitted into the groove 217 on the outer periphery of the touch key film 216, thereby more reliably preventing water from entering from the display unit 250 side to the operation unit 230 side. Thus, by providing the rib 221 on the back surface 220b of the panel cover 220, water intrusion from the display unit 250 side to the operation unit 230 side can be prevented. Details will be described later.

  The drain hole 220e drops water droplets generated in the operation unit 230 on the touch key film 216 downward on the front end side (front side).

  The upper surface 220a of the panel cover 220 is the same as the surface 200a (see FIG. 1) of the operation panel 200. Further, the end portion 220c of the panel cover 220 is substantially the same as the end portion 200b (see FIG. 1) of the surface 200a of the operation panel 200. A display sheet as shown in FIG. 4 is attached to the upper surface 220 a of the panel cover 220. This display sheet is partially light-shielding and the other part is translucent. The display sheet is for displaying a range where the user should perform a touch operation, that is, an operation button. The translucent part of the display sheet functions as a frame line of operation buttons, for example. Instead of covering the upper surface 220a of the panel cover 220 with a display sheet, a configuration in which a range to be touched by the user is printed in advance on the upper surface 220a.

<Water entry prevention structure>
Next, the water intrusion prevention structure will be described.
11A and 11B are cross-sectional views of the main part for explaining prevention of water intrusion. FIG. 11A shows an example in which the rib contacts the touch key film, and FIG. 11B shows that the rib is fitted in the groove. This is an example of the case.
In the present embodiment, in order to prevent water from adhering to the touch key film 216 of the operation unit 230 of the operation panel 200 (particularly, the touch keys 234 to 247 of the operation unit 230), the back surface 220a of the panel cover 220 is provided. A rib 221 for preventing water from entering the operation unit 230 is provided. As shown in FIG. 9, the rib 221 is formed on the back surface 220 a of the panel cover 220 at the boundary between the operation unit 230 and the display unit 250 over the longitudinal direction. When the panel cover 220 is attached to the panel main body 210, the rib 221 comes into contact with the touch key film 216 (see FIG. 11A). Moreover, a part of rib 221 is engage | inserted by the groove part 217 of the outer periphery of the film 216 for touch keys (refer FIG.11 (b)).

  Since the touch key film 216 is flexible, when the rib 221 on the back surface 220 a of the panel cover 220 is pressed against the touch key film 216, the pressed touch key film 216 follows the pressing of the rib 221 and deforms. Then, the protruding end portion of the rib 221 and the upper surface of the touch key film 216 are in close contact with each other.

  Further, as shown in FIG. 11B, a part of the rib 221 is fitted into a groove portion 217 provided on the outer periphery of the touch key film 216. That is, a rib 221 (see FIG. 9) is formed in the groove 217 provided on the outer periphery of the rear end 216b of the touch key film 216 so as to protrude inward from the back surface 220b of the panel cover 220 (see FIGS. 9 and 10). 9 and FIG. 10) are engaged. This more reliably prevents water (moisture-containing air) from entering the touch key film 216 from the display unit 250 side.

  Thus, the rib 221 is provided at the boundary between the operation unit 230 and the display unit 250 on the back surface 220a of the panel cover 220. As a result, when water enters the operation panel 200 from the outside, or water droplets are formed on the display unit 250 of the operation panel 200 due to condensation (the washing machine 100 is often placed near a bathroom or the like). In any case, the rib 221 serves as a standing wall that prevents water from entering the operation unit 230 from the display unit 250 side (particularly, touch keys 234 to 247 of the operation unit 230). It is possible to prevent water from entering the side.

  Here, it is possible that condensation also occurs in the operation unit 230 (particularly, the touch type keys 234 to 247 of the operation unit 230) on the back surface 220a of the panel cover 220, and water droplets are formed on the touch key film 216. However, since the area on the touch key film 216 of the touch keys 234 to 247 of the operation unit 230 is smaller than the area of the back surface 220a of the panel cover 220, the condensation that occurs in places other than the operation unit 230 There are many. Therefore, it is important not to allow water droplets generated in places other than the operation unit 230 to enter the operation unit 230 side. The rib 221 can effectively prevent water from entering from the display unit 250 side to the operation unit 230 side.

<Water discharge structure>
Next, the water discharge structure will be described.
As described above, water may adhere to the touch key film 216 of the operation unit 230 due to condensation or the like.
In the present embodiment, in addition to the operation panel 200 being inclined downward toward the front, the end 216a of the operation panel 200 is gently bent downward. Accordingly, the end portion 220c of the panel cover 220 is also curved downward. Further, the front end 216a of the touch key film 216 disposed below the panel cover 220 is also bent downward on the front side (front side). Further, an end 220c of the panel cover 220 is formed downward from the drain hole 220e.

Therefore, even if water droplets are present on the back surface 220b of the panel cover 220, the operation panel 200 itself has a downward slope, and further, the end 216a of the operation panel 200 is gently bent downward. The water drops travel along the back surface 220b of the panel cover 220 to the end portion 220c of the panel cover 220. Similarly, even if water droplets are present on the touch key film 216, the touch key film 216 is disposed in a downward slope, and the front end portion 216a of the touch key film 216 is gently bent downward. As a result, the water droplet travels through the touch key film 216 to the end 220 c of the panel cover 220.
And the water droplet which moved to the edge part 220c of the panel cover 220 is guide | induced to the drain hole 220e, and is discharged | emitted below from the drain hole 220e.

  As described above, in the washing machine 100 of the present embodiment, the operation panel 200 is disposed adjacent to the touch key film 216 having the detection electrodes for detecting the touch operation and the touch key film 216. A panel main body 210 having a display unit 250, a touch key film 216 of the panel main body 210 and a panel cover 220 covering the display unit 250, and a back surface 220 b of the panel cover 220 and an upper surface of the touch key film 216. In the meantime, a rib 221 is provided to prevent water from entering the detection electrode. The rib 221 protrudes from the back surface 220 b of the panel cover 220 toward the touch key film 216 at the boundary between the touch key film 216 and the display unit 250. When the panel main body 210 and the panel cover 220 are assembled, the rib 221 comes into contact with the upper surface 216 a of the touch key film 216 or the groove 217 provided at the edge of the touch key film 216.

  Accordingly, it is possible to prevent water from entering from the display unit 250 to the operation unit 230 (particularly, the touch keys 234 to 247 of the operation unit 230) at a low cost by a simple configuration in which the rib 221 is provided. A rib 221 (see FIG. 9) is formed in the groove 217 provided on the outer periphery of the rear end portion 216b of the touch key film 216 so as to protrude inward from the back surface 220b of the panel cover 220 (see FIGS. 9 and 10). 9 and FIG. 10) is engaged, water permeation itself onto the touch key film 216 from the display unit 250 side is prevented.

  Further, the water droplets on the back surface 220b of the panel cover 220 or the touch key film 216 are formed on the edge of the panel cover 220 by the downward gradient of the front end portion 216a of the touch key film 216 or the touch key film 216 and subsequent bending. It moves to 220c and is discharged downward from the drain hole 220e. As described above, the operation panel 200 is inclined forward and is steeply inclined downward at the end portion 200b. Therefore, even if water droplets are formed inside the panel cover 220 of the operation panel 200, the water droplets are not formed. It flows forward and is discharged to the outside from the drain hole 220e of the panel cover 220.

  By the way, if the operation panel has a configuration in which the panel cover and the touch key film are in close contact with each other, there is no gap between them, so that water does not enter. However, such an operation panel having a structure in which the panel cover and the touch key film are in close contact with each other has disadvantages that the assembly cost is high, the layout flexibility is small, and the specification cannot be easily changed. On the other hand, in this embodiment, the panel body 210 and the panel cover 220 are configured as separate parts, so that the part cost and assembly cost can be kept low, and the button layout and the like by changing the layout and specifications are simple. There is an advantage that can be done.

The above-described exemplary embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
For example, in the present embodiment, an example of a vertical washing machine has been described, but the present invention can be similarly applied to a drum-type washing machine and a washing / drying machine. Further, the present invention can be similarly applied to a device that should take into account the water intrusion into the key operation unit, for example, a dryer or a humidifier.
