  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
1 and 2, a water tub 2 is suspended in a body 1 of a drum-type washing machine, and a rotating drum 3 formed in a bottomed cylindrical shape in the water tub 2 has its axial direction facing the front. Inclined downward from the side toward the back side and is rotatably arranged. On the front side of the water tank 2 is formed a clothing doorway 4 leading to the opening end of the rotating drum 3, and an opening provided on an upward inclined surface formed at the front portion of the front frame body 5 constituting the front surface of the main body 1. By opening the door 9 that opens and closes the part 6, the laundry in the rotary drum 3 can be taken in and out through the clothing entrance 4. Since the door 9 is provided on the upward inclined surface, the work for putting in and out the laundry can be carried out without bending the waist, and generally the workability of the drum type washing machine for taking in and out the laundry from the sideways opening is provided. The evil has been improved.

  A large number of through holes 10 communicating with the water tank 2 are formed on the peripheral surface of the rotating drum 3, and are driven to rotate in the forward and reverse directions by a motor 11 attached to the back side of the water tank 2. A water injection pipe 12 and a drain pipe 13 are connected to the water tank 2, and water injection and drainage into the water tank 2 are performed by controlling the water injection valve 14 and the drain valve 15.

  An operation display panel 16 is disposed on the upper part of the front frame 5, and a detergent charging case 17 (shown in FIG. 1) is disposed on the front frame 5 so as to be able to be drawn forward. Prior to driving, the user puts the detergent into the detergent case 17 and operates the pressing operation unit 21 arranged on the operation display panel 16 as necessary to set the desired driving content, start driving, temporarily It is possible to stop and recognize the progress of driving.

  When the door 9 is opened and the laundry is put into the rotating drum 3 to start operation, the water injection valve 14 is opened, water is poured into the detergent charging case 17, and the detergent that has been poured therein is being poured. A predetermined amount of water is injected into the water tank 2 through the water injection pipe 12, and the rotating drum 3 is driven to rotate by the motor 11 to start the washing process. The laundry in the washing process is washed by repeating the stirring operation of being lifted and dropped in the rotational direction by the rotation of the rotary drum 3.

  After the required washing time, the drain valve 15 is opened, the dirty washing liquid is discharged from the drain pipe 13, and the washing liquid contained in the laundry is dehydrated by a dehydrating operation of rotating the rotating drum 3 at a high speed. Water is poured into the water tank 2 from the water injection pipe 12 and a rinsing process is performed. Also in the rinsing process, the laundry is rinsed by repeating the stirring operation by the rotation of the rotating drum 3.

  3 and 5, the operation display panel 16 is disposed between the upper part of the front frame 5 and the top plate 18, and the surface of the transparent resin portion 19 is covered with an insert-molded film 20 (PET film). It forms a decorative surface that is colored and printed, and has a pressing operation portion 21 and a light emitting display portion 22. Inside the operation display panel 16, there is a control board unit 25 in which a switch 23, a light emitting element 24, and the like are mounted at positions corresponding to the pressing operation unit 21 and the light emitting display unit 22, respectively. The light guide path 26 for irradiating the portion 22 and the operation member 28 having the button portion 27 for pressing the switch 23 by the pressure generated by the user pressing the pressing operation portion 21 are fixed to the operation display panel 16. The Since the diffusing film 29 is interposed between the operation display panel 16 and the operation member 28, the light emitted from the light emitting element 24 is diffused to make the light emitting display portion 22 of the operation display panel 16 substantially uniform. Can emit light.

  Note that the transparent resin portion 19 and the film 20 are not necessarily transparent and may be translucent.

  While viewing the menu displayed on the light emitting display unit 22 by the light emitting element 24, the user presses the pressing operation unit 21 to select a desired driving course and starts washing, rinsing, dehydration, and the like. Although there are many display menus in the light emitting display unit 22, since it becomes difficult to use if light is emitted even to an irrelevant display, only the display menu that can be selected emits light.

  For example, as shown in FIG. 6, “Course” which is one of the pressing operation units 21 is pushed several times, and when a desired “Random” course is set, for example, a “Start” button is pushed to start driving. Since only the display section of the set course emits light during driving, it is easy for the user to grasp the usage status.

  For example, course names such as “Omakase” have a wide range, and in order to make it easy for the user to see when emitting light, it is necessary to emit light uniformly not only to the center but also to the end of the display range. If the number of the light emitting elements 24 is increased, the effect can be obtained, but the cost is increased. Therefore, by disposing the diffusion film 29 on which the ink having a high light diffusion effect is printed between the operation display panel 16 and the operation member 28, the light emission in the light guide path 26 is diffused to illuminate the light emission display unit 22. Without increasing the number of light emitting elements, light can be emitted substantially uniformly not only from the center of the display range but also from end to end. Further, since the light is emitted uniformly, the visibility is improved, and if the periphery of the display range where light is emitted as shown in FIG.

  What has been described above is a state in which the light emitting display unit 22 emits light at the start of driving and during driving. However, when not driving (when the light is turned off), it is clear that nothing is displayed on the light emitting display unit 22 in terms of design. And a sense of luxury increases. This is a printing process called a half mirror. For example, the display menu such as “Random” is a print character of the film 20 that is insert-molded on the operation display panel 16. Appearance color should be almost the same.

  For printing the character part, ink having a certain diffusion effect is used. However, since the color is limited, it cannot be made the same as the appearance color, and the display menu can be clearly seen when the light is turned off. Therefore, by disposing the diffusion film 29 between the operation display panel 16 and the operation member 28, a substantially uniform diffusion effect at the time of light emission can be secured by the diffusion film 29. At the same time, the characters can be erased when the lights are turned off by selecting the printing ink of the film 20 insert-molded on the operation display panel 16 so as to have substantially the same color as the appearance color. Therefore, the visibility and design at the time of lighting can be improved, and the design at the time of turning off can be improved.

  FIG. 4A shows a state where the diffusion film 29 is attached to the back surface of the operation display panel 16.

  In FIG. 4 (B), the front view (upper stage figure) which shows the notch 30 of the diffusion film lower part in FIG. 4 (A), the front view of the state which the notch 30 is latched by the latching | locking part 32 (middle stage figure). The aa sectional view (lower stage figure) in the state where notch 30 is locked to locking part 32 is shown.

  4B, a front view showing the cut 31 at the top of the diffusion film in FIG. 4A (upper view), and a front view showing the state where the cut 31 is locked to the locking portion 33 (middle row). Figure) shows a cross-sectional view (lower view) of the state in which the cut 31 is locked to the locking portion 33.

  The diffusion film 29 is provided with a plurality of substantially U-shaped cuts 30 and 31, and locking portions 32 and 33 are provided at corresponding positions on the back surface of the operation display panel 16 to elastically deform the cuts 30 and 31. The locking portions 32 and 33 are locked.

  Since the substantially U-shaped cuts 30 and 31 are cut toward the outer peripheral side of the diffusion film 29, the cuts 30 and 31 have a vertically symmetrical shape. Further, the locking portions 32 and 33 are provided with convex portions for locking toward the inner side of the diffusion film 29.

  The diffusion film 29 is, for example, a PET film having a thickness of about 0.2 mm, and the cuts 30 and 31 are easily applied by Thomson processing and elastically deformed with a light force, so that they can be easily attached to the engaging portion. The Thomson process is to make a slit with a thin blade such as a razor, and naturally, the cuts 30 and 31 of the locking portions 32 and 33 are elastically deformed and locked. Therefore, once the locking portions 32 and 33 are in the locked state, a force acts in a direction to enter the locking portions 32 and 33 so that the elastically deformed portion returns, so that the diffusion film 29 is locked into the locking portions 32 and 33. It is not easy to get out of it.

  Since the diffusion film 29 is an elastic member, when the diffusion film 29 is attached to the operation display panel 16, the operation display panel 16 is turned face down, and then the control board unit 25 to which the operation member 28 is attached is operated. When assembling with the display panel 16, the operation display panel 16 is faced up and assembled from above.

  At this time, if the diffusion film 29 is easily detached from the operation display panel 16, the assemblability deteriorates. For example, there is a method of bonding the diffusion film 29 to the operation display panel 16 with a double-sided tape. The work at the time of assembling that has to be peeled off also increases. Therefore, as described above, when the diffusion film 29 is fitted into the operation display panel 16, the substantially U-shaped cuts 30 and 31 are elastically deformed and locked to the locking portions 32 and 33. Assembly can be improved.

  The direction of the plurality of cuts is set in the direction of the cuts 30 and the locking portions 32 as shown by the cross section aa in FIG. 4B at the position near the lower side of the diffusion film 29, for example, at the position near the upper side. As shown in the cross section bb in FIG. 4C, the notches 31 and the locking portions 33 are set to face each other, and the notches 30 and 31 are opposed to each other, and the protrusions of the locking portions 32 and 33 are also formed. They are provided so as to face each other. With such a configuration, the diffusion film 29 can be firmly attached to the operation display panel 16 by fixing the diffusion film 29 so as to be sandwiched by the locking portions 32 and 33 from the outer peripheral side thereof, thereby improving the reliability. Can do.

  The locking portions 32 and 33 can be more securely held at the end than the center of the diffusion film 29. However, when the locking portions 32 and 33 are provided at the end, the strength when the substantially U-shaped cuts 30 and 31 are elastically deformed decreases. There is a case. Therefore, if the bases of the substantially U-shaped cuts 30 and 31 are away from the outer periphery of the diffusion film 29 as described above, the width of the film where stress is concentrated when elastically deformed can be sufficiently secured. The diffusion film 29 can be more securely attached to the operation display panel 16 without being damaged when the diffusion film 29 is attached, and the reliability can be improved.

  As described above, the drum-type washing machine according to the present invention does not need to increase the number of issuing elements so much even when a long horizontal display is lit, and evenly extends from one end of the character to the other end. Because it can be shining, it will not only be excellent in appearance, it will also make it easier to recognize the course selected by the user, it will be cheap, it will be easy to assemble, and reliability will be improved, so other types of washing It is also useful for machines.
