Further, the operation panel 30 may be provided with a display unit (not shown) for displaying.

FIG. 3 is an exploded perspective view of the door 20 and the operation panel 30 as viewed from the front side. As shown in FIG. 3, the operation panel 30 is roughly composed of a panel front member (front member) 31 and a panel back member (back member) 32. The operation panel 30 is attached to and detached from the door 20 by being divided into a panel front member 31 and a panel back member 32.

Subsequently, the procedure for attaching the operation panel 30 to the door 20 will be described. 4 (a) to 4 (c) are views showing the procedure for attaching the operation panel 30 to the door 20, and are perspective views of the vicinity of the upper end portion of the door 20 as viewed from the back side.

FIG. 4A shows the upper end portion of the door 20 before the operation panel 30 is attached. A panel mounting portion 21 for mounting the operation panel 30 is provided at the upper end portion of the door 20. A panel insertion base 211 is provided on the upper end edge of the panel mounting portion 21.

On the other hand, the panel front member 31 of the operation panel 30 is provided with an insertion portion 311 (see FIG. 3) at the lower end edge thereof. When the operation panel 30 is attached to the door 20, only the panel front member 31 is attached to the door 20 as shown in FIG. 4 (b). At this time, the insertion portion 311 of the panel front member 31 is attached so as to be inserted into the panel insertion base 211 of the door 20 from above.

After that, as shown in FIG. 4C, the panel back member 32 is attached from the back side so as to overlap the panel front member 31, and is fixed by screwing. Some of the screws used at this time (the screws near the upper part) fix the panel front member 31 to the panel back member 32. The remaining screws (screws near the lower part) fix the panel back member 32 to the panel mounting portion 21.

When the operation panel 30 is removed from the door 20, the procedure is the reverse of the above description. Further, the operation panel 30 can be attached / detached while the door 20 is attached to the washing machine main body 10.

As described above, in the drum-type washing machine 1 according to the first embodiment, the operation panel 30 is detachably attached to the door 20. Therefore, for example, when it is necessary to replace the operation panel 30, it is not necessary to remove the operation panel 30 from the inside of the door after removing the outer cover member of the door, and the maintainability of the operation panel 30 is improved. Can be made to.

Further, the operation panel 30 is composed of a panel front member 31 and a panel back member 32, and the panel back member 32 is detachable from the panel front member 31. This facilitates the work of attaching and detaching the operation panel 30 to and from the door 20. The effect is particularly remarkable when the operation panel 30 is tilted with respect to the door 20.

Even in such a case), the door 20 and the operation panel 30 can be easily manufactured, and the manufacturing cost can be suppressed.

[Embodiment 2]
In the second embodiment, a more suitable structure of the operation panel 30 will be described. FIG. 5 is an exploded perspective view of the panel front member 31. FIG. 6 is an exploded perspective view of the panel back member 32.

As shown in FIG. 5, the panel front member 31 is composed of a front glass plate 33, a glass cover 34, and a frame member 35. The frame member 35 is a resin member arranged on the back side of the panel front member 31, and is formed with the above-mentioned insertion portion 311 and screw holes. Further, the frame member 35 is formed with an opening 351.

The front glass plate 33 is arranged on the front side of the frame member 35. The glass cover 34 holds the front glass plate 33 against the frame member 35 so as to sandwich the outer periphery (three sides excluding the lower side) of the front glass plate 33 and the frame member 35. The glass cover 34 can be attached to the front glass plate 33 and the frame member 35 which are overlapped with each other so as to be inserted from above. As described above, the structure in which the front glass plate 33 is superposed on the frame member 35 and the periphery thereof is held by the glass cover 34 facilitates a large screen of the operation panel 30 (large area of the front glass plate 33). Further, since the peripheral edge of the front glass plate 33 is mechanically sandwiched between the glass cover 34 and the frame member 35, the front glass plate 33 can be reliably prevented from peeling off from the frame member 35.

As shown in FIG. 6, the panel back member 32 is composed of a panel circuit unit (operation display circuit unit) 36, a substrate case member 37, and a back cover 38. The panel circuit unit 36 is an integral combination of a touch panel and an operation display circuit board for driving the touch panel. The panel back member 32 is configured such that the panel circuit portion 36 is fitted into the bottomed frame-shaped board case member 37 and fixed, and the board case member 37 is fixed to the front side of the back cover 38 by screwing. (See Fig. 3). Therefore, the substrate case member 37 has a plurality of protrusions along the outer circumference thereof, and screw holes are formed in the protrusions. It should be noted that the use of the board case member 37 in the operation panel 30 is not essential, and even if the operation display circuit board of the panel circuit unit 36 is provided with a screw hole and the panel circuit unit 36 is directly screwed to the back cover 38. Good. Further, in the panel circuit unit 36, a capacitance type touch panel is used so that the operation can be performed via the front glass plate 33.

In the second embodiment, in the panel circuit unit 36, the touch panel is fixed to the operation display circuit board, and the panel circuit unit 36 in which the touch panel and the operation display circuit board are combined is fixed to the panel back member 32. Is illustrated. However, the present invention is not limited to this, and a panel circuit is formed by fixing the touch panel to the panel front member 31 and combining the panel front member 31 and the panel back member 32 to which the operation display circuit board is fixed. The unit 36 may be configured.

In the operation panel 30 in which the panel front member 31 and the panel back member 32 are combined, the panel circuit portion 36 is arranged between the front glass plate 33 and the back cover 38 of the panel front member 31. At this time, the touch panel of the panel circuit unit 36 is fitted into the opening 351 of the frame member 35 and faces the front glass plate 33. With such a configuration, the touch panel can be protected by the front glass plate 33, and the touch panel can be arranged close to the front glass plate 33.

At this time, the touch panel is only close to the front glass plate 33 and does not need to be in contact with the touch panel. That is, in the operation panel 30 to be assembled, the touch panel may be separated from the front glass plate 33, which facilitates the manufacture of each member of the operation panel 30 (it becomes easy to provide a margin in the dimensions of each member). .. However, the touch panel may be in contact with the front glass plate 33 without being separated from the front glass plate 33. In this case, the sensitivity of the touch panel is improved.

As described above, in the operation panel 30 according to the second embodiment, the panel circuit unit 36 is attached to the back cover 38 to form the panel back member 32. Therefore, by removing the panel back member 32, that is, by removing the back cover 38, the panel circuit portion 36 is also removed at the same time, and the maintainability is further improved.

For example, in a configuration in which the panel circuit section is provided on the door, if the panel circuit section needs to be replaced and a screw or the like is dropped when the panel circuit section is removed from the inside of the door, the dropped screw will be used on the door. It may get inside, and in such a case, it is necessary to disassemble the entire door and take out the dropped screw.

In the configuration of the operation panel 30, it is possible to remove only the panel back member 32 and replace the panel circuit unit 36 together with the panel back member 32, which facilitates maintenance such as replacement of the panel circuit unit 36. Further, even when only the panel circuit unit 36 is replaced, the panel circuit unit 36 can be removed from the back cover 38 with the panel back member 32 removed from the door 20. Therefore, there is no risk of the screw falling inside the door 20.

Further, by attaching the panel circuit portion 36 to the back cover 38, the panel front member 31 does not include the panel circuit portion 36, and the panel front member 31 can be reduced in weight. This makes it possible to simplify the configuration for attaching the panel front member 31 to the door 20. For example, as described above, the panel front member 31 can be attached to the door 20 by a simple operation such as inserting the insertion portion 311 of the panel front member 31 into the panel insertion base 211 of the door 20. Further, since the panel front member 31 is reduced in weight, even if the panel front member 31 is accidentally hit by something during transportation or maintenance work, the impact at that time is reduced, and the front glass plate 33 is reduced. The risk of damage is reduced.

Further, in the above description, the panel circuit unit 36 is fixed to the back cover 38 by screwing, and the operation display circuit board (or the substrate case member 37) in the panel circuit unit 36 is provided with a plurality of screw holes. ing. However, some of these screw holes may be through which screws for fastening the panel back member 32 and the panel front member 31 are passed. That is, the operation panel 30 has a screw that fastens the panel front member 31 (for example, the frame member 35), the panel circuit unit 36 (for example, the operation display circuit board), and the panel back member 32 (for example, the back cover 38) together. It may be a thing. As a result, the number of screws used in the operation panel 30 can be reduced.

[Embodiment 3]
In the third embodiment, another suitable structure of the operation panel 30 will be described.

In the description of the second embodiment, in the panel back member 32, the panel circuit portion 36 is attached to the back cover 38 by screwing, but the present invention is not limited to this.
