Abstract
The washing machine includes a touch panel type operation display unit. The operation display unit includes a front surface light-transmitting plate and a transparent electrode, which are adhered to and held on the front surface side of the same holding member.
Description
Technical Field
One aspect of the present invention relates to a washing machine including a touch panel type operation display unit.
Background
Conventionally, there is a structure in which a touch panel type operation display unit is provided on the front surface of a washing machine (for example, japanese patent No. 6254920, japanese patent No. 6099521, japanese patent No. 6396009, japanese patent No. 6393090, and japanese patent No. 6511643). The touch panel type operation display unit is generally configured to include a light transmitting plate such as a glass plate, a transparent electrode, and a circuit board from the front side.
Disclosure of Invention
In the conventional touch panel type operation display unit, the glass plate and the transparent electrode are usually mounted on separate members and held.
In this case, there is a problem that the distance between the surface of the glass plate serving as the operation surface of the touch panel and the transparent electrode varies, and the sensitivity of the touch panel becomes unstable.
In addition, in the touch panel type operation display unit, the circuit board may be replaced during maintenance such as coping with a failure or upgrading the version of the control program. In the conventional configuration, the glass plate and the transparent electrode are often separated during maintenance of the operation display unit, and when the glass plate and the transparent electrode are separated and then assembled again, foreign matter may be mixed between the glass plate and the transparent electrode. If a foreign substance is mixed between the glass plate and the transparent electrode, problems occur such as a decrease in sensitivity of the touch panel or a blocking of the display portion by the foreign substance.
In addition, in the conventional configuration, the transparent electrode is replaced at the same time when the circuit board is replaced. Since the transparent electrode is basically a member that is difficult to malfunction and deteriorate, in this case, the member that is not deteriorated is also a replacement target, which is disadvantageous in terms of cost.
In addition, in order to prevent foreign matter from entering between the glass plate and the transparent electrode during maintenance, the glass plate may be replaced. However, in this case, since the replacement object parts are further increased, there is a disadvantage in that the disadvantage in terms of cost becomes larger.
An aspect of the present invention is made in view of the above problems, and a first object of the present invention is to provide a washing machine in which a distance between a touch panel operation surface and a transparent electrode is not varied and sensitivity of a touch panel is stable in a touch panel type operation display unit. A second object of the present invention is to provide a washing machine capable of preventing foreign matter from entering between a glass plate and a transparent electrode during maintenance of an operation display unit and reducing the number of parts to be replaced.
In order to solve the above problem, a washing machine according to one aspect of the present invention includes a touch panel type operation display unit having a front surface light-transmitting plate and a transparent electrode, which are adhered to and held on a front surface side of a same holding member.
According to the above configuration, both the front surface light-transmitting plate and the transparent electrode are adhered to and held by the same holding member. Thus, as compared with the case where the light-transmitting plate and the transparent electrode are held by separate members, the variation in distance between the front surface light-transmitting plate and the transparent electrode is reduced, and the sensitivity of the touch panel is stabilized.
Further, the washing machine is configured to: the operation display unit includes a circuit board having a light emitting element, the circuit board being mountable on a back surface side of the holding member, and a reflector structure for diffusing light emitted from the light emitting element is integrally molded in the holding member.
According to the above configuration, the number of components in the operation display portion can be reduced, dimensional variations and assembly variations of each component can be eliminated, and the cost of molding cost and assembly cost of the operation display portion can be suppressed.
Further, the washing machine is configured to: the holding member is provided with an opening portion for connecting the transparent electrode on the front surface side and the circuit board on the back surface side, and the transparent electrode is electrically connected to a connector of the circuit board via the opening portion.
According to the above configuration, the electrical connection between the transparent electrode and the circuit board can be easily released when the circuit board is replaced, and the transparent electrode and the circuit board can be separated only by replacing the circuit board. Accordingly, the front surface light-transmitting plate and the transparent electrode do not need to be separated from each other, and there is no possibility that foreign matter is mixed between the front surface light-transmitting plate and the transparent electrode, and therefore, it is possible to prevent problems such as a decrease in sensitivity of the touch panel due to the mixing of foreign matter. In addition, by making only the circuit board the component to be replaced, the number of components to be replaced can be reduced.
Further, the washing machine is configured to: the circuit board is configured to be mounted on the back surface side of the holding member in a state of being fitted in the board housing member, and a shield member is interposed between the board housing member and the holding member so as to surround the circuit board.
According to the above configuration, the waterproof structure of the circuit board can be easily obtained by the sealing member interposed between the board housing member and the holding member.
Further, the washing machine is configured to: a cover member is provided, which is clamped around the front surface light-transmitting plate and the holding member.
According to the above configuration, the front transparent plate and the periphery of the holding member are mechanically sandwiched by the cover member, and therefore, the front transparent plate can be reliably prevented from being peeled off from the holding member. Further, since the cover member covers the periphery of the portion where the front surface light-transmitting plate and the holding member are bonded, it is possible to prevent water from entering from the periphery of the portion where the light-transmitting plate and the holding member are bonded to the transparent electrode.
In the washing machine according to one aspect of the present invention, the front surface light-transmitting plate and the transparent electrode are adhered to the same holding member, and the transparent electrode is held, so that the distance deviation between the front surface light-transmitting plate and the transparent electrode is reduced, and the sensitivity of the touch panel is stabilized.

Detailed Description
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view showing an external appearance of a drum-type washing machine (washing machine) 1 according to a first embodiment. The drum-type washing machine 1 may be a washing machine that performs only washing without drying, or may be a washing and drying machine that can perform washing and drying. Further, although the washing machine 1 shown in fig. 1 exemplifies a drum-type washing machine, the present invention is not limited thereto, and a washing machine to which the present invention is applied may be a vertical-type washing machine.
The drum-type washing machine 1 is generally composed of a washing machine main body 10, a door 20, and an operation panel (operation display unit) 30, and the washing machine main body 10 has a laundry inlet on its front surface. The door 20 is pivotally supported by the washing machine main body 10 via a hinge so as to be rotatable, and is provided to open and close a laundry inlet on the front surface of the washing machine main body 10. The operation panel 30 is attached to the door 20 so as to extend from an upper end portion of the door 20.
The operation panel 30 is assembled to an upper portion of the door 20. Accordingly, the operation panel 30 rotates integrally with the door 20 with respect to the washing machine body 10. However, the operation panel 30 is not formed to cover the laundry inlet, unlike the door 20. The operation panel 30 is attached to the door 20 such that its panel surface is inclined rearward in a direction not parallel to the vertical plane. This makes the operation panel 30 easy to see when the user looks from above, and is highly visible and operable.
Fig. 2 is an exploded perspective view of the door 20 and the operation panel 30 as viewed from the front surface side. As shown in fig. 2, the door 20 and the operation panel 30 are substantially constituted by the operation panel 30, the door front surface member 21, and the door back surface member 22.
For example, when the operation panel 30 is assembled to the door 20, the following mounting method can be considered: first, the operation panel 30 is inserted into the upper end portion of the door front surface member 21, and then the door back surface member 22 is attached from the back surface side so as to overlap the operation panel 30 and the door front surface member 21, and is fixed by screw fastening. In the case where the operation panel 30 is detached from the door 20, the procedure is reversed from the above description. Alternatively, the operation panel 30 may be configured such that only the operation panel 30 can be attached and detached in a state where the door front surface member 21 and the door back surface member 22 are assembled.
Next, a more detailed configuration of the operation panel 30 will be described. Fig. 3 is an exploded perspective view of the operation panel 30. Fig. 4 is a longitudinal sectional view of the operation panel 30. As shown in fig. 3 and 4, the operation panel 30 includes a front glass plate (front light-transmitting plate) 31, a transparent electrode 32, a display sheet 33, a reflector member 34, a circuit board 35, a board case member 36, and a glass cover 37. The front glass plate 31 may be a transparent resin plate such as acrylic or polycarbonate, or may be partially transparent or translucent. Since the transparent electrode 32 and the display sheet 33 are thin members, the transparent electrode 32 and the display sheet 33 are integrally illustrated in a state of being overlapped with each other in the cross-sectional view of fig. 4 for convenience.
The transparent electrode 32 is an electrode portion for sensing a finger of a user operating the touch panel. The display sheet 33 is a sheet having a light-transmitting background such as a light-shielding portion and characters, frames, and the like, and displays characters and frames at a portion where the light-emitting element provided on the circuit board 35 emits light (in fig. 3, the characters and frames on the display sheet 33 are not illustrated). The reflector member 34 is a holding member that holds the front glass plate 31, the transparent electrode 32, and the circuit board 35 in a predetermined positional relationship. The substrate case member 36 is a member that holds the circuit substrate 35 and is mounted on the back surface side of the reflector member 34.
The reflector member 34 is a holding member for the front glass plate 31, and is provided with a plurality of small holes for diffusing and Emitting light emitted from light Emitting elements (for example, leds (light Emitting diodes), not shown) provided on the circuit board 35 forward (toward the front glass plate 31, the transparent electrodes 32, and the display sheet 33). Further, openings (opening portions) 341 and 331 are also provided in the reflector member 34 and the display sheet 33, and the openings (opening portions) 341 and 331 are used to electrically connect the transparent electrode 32 and the circuit substrate 35. That is, since the transparent electrode 32 is a flexible circuit board, a part thereof is bent (or bent) so as to pass through the openings 331 and 341 and be connected to the circuit board 35 on the back surface side of the reflector member 34.
The front glass plate 31, the transparent electrode 32, and the display sheet 33 are attached to the front surface side of the reflector member 34 using a double-sided tape not shown.
Specifically, first, the display sheet 33 and the transparent electrode 32 are sequentially attached to the front surface of the reflector member 34. Shapes or marks for mutual positioning are provided in the transparent electrode 32, the display sheet 33, and the reflector member 34. For example, the transparent electrode 32 and the display sheet 33 are provided with positioning portions such as slits and holes. The display sheet 33 and the transparent electrode 32 are positioned and adhered to the front surface of the reflector member 34 by being arranged so as to overlap with a positioning portion such as a hole provided in the reflector member 34.
Next, the reflector member 34 is attached to the front surface glass plate 31. The reflector member 34 is provided with a positioning portion, and the front surface glass plate 31 is aligned with the positioning portion. The positioning portion on the front glass plate 31 side may be provided with a dedicated shape or mark, but the edge of the front glass plate 31, a pattern, or the like is preferably used. This prevents the front glass plate 31 from being provided with an extra mark or the like, thereby improving the design. Further, the positioning portion of the reflector member 34 may be provided with no special shape or mark, and a rib or the like covering the side end surface of the front glass plate 31 may be used.
A double-sided tape is attached to the peripheral edge portion of the front glass plate 31, and the reflector member 34 is attached to the front glass plate 31 while being positioned. As described above, by providing the positioning portion in the reflector member 34 and positioning the transparent electrode 32, the display sheet 33, and the front surface glass plate 31 with reference to the reflector member 34, it is possible to minimize positional deviation among the transparent electrode 32, the display sheet 33, and the front surface glass plate 31.
The display sheet 33 may be contained in the reflector member 34, and may be contained in the transparent electrode 32. Basically, the front glass plate 31 and the transparent electrode 32 are attached to the reflector member 34 and the display sheet 33, respectively, but the front glass plate 31 and the transparent electrode 32 may be attached by a double-sided tape in a part of the area.
In the operation panel 30, a reflector structure (i.e., a plurality of small holes formed in the reflector member 34) for diffusing the irradiation light of the LED is integrally formed in the reflector member 34 having the circuit board 35 mounted on the back surface side thereof. This can reduce the number of components in the operation panel 30, and can suppress the cost of the operation panel 30 in terms of molding cost and assembly cost. Further, by integrating the reflector structure to the holding member to which the front surface glass plate 31 is bonded, the transparent electrode 32 can be bonded to the same holding member.
The circuit board 35 is embedded on the front surface side with respect to the board housing member 36. The substrate case member 36 in which the circuit substrate 35 is embedded is mounted on the back surface side of the reflector member 34 by screw fastening. Thereby, the circuit board 35 can be disposed at a predetermined position on the rear surface side of the reflector member 34.
When the circuit substrate 35 is replaced, the electrical connection between the transparent electrode 32 and the circuit substrate 35 can be easily released and reconnected. For example, a connector capable of connecting a part of the transparent electrode 32 is provided on the circuit board 35, the transparent electrode 32 and the circuit board 35 are electrically connected using the connector, and the connection can be easily released if the connector is removed.
Further, a gasket (sealing member) 38 is interposed between the substrate case member 36 and the reflector member 34 so as to surround the circuit board 35, and the gasket 38 can easily provide a waterproof structure of the circuit board 35.
A glass cover (cover member) 37 is attached to insert the front surface glass plate 31 and the reflector member 34, which are overlapped with each other, from above. As described above, the front glass plate 31 is overlapped with the reflector member 34, and the periphery of the front glass plate 31 and the reflector member 34 is held by the glass cover 37, so that the peripheral edge portions of the front glass plate 31 and the reflector member 34 are mechanically sandwiched by the glass cover 37, and therefore, the peeling of the reflector member 34 of the front glass plate 31 can be reliably prevented. Further, since the glass cover 37 covers the periphery of the portion where the front glass plate 31 and the reflector member 34 are bonded, water can be prevented from penetrating into the back surface of the front glass plate 31, and stability of the touch sensitivity can be ensured.
In the operation panel 30 according to the present embodiment, both the front surface glass plate 31 and the transparent electrode 32 are stuck on the reflector member 34. That is, the front surface glass plate 31 and the transparent electrode 32 are held by the same member (reflector member 34). Therefore, as compared with the case where the front glass plate and the transparent electrode are held by separate members, the distance deviation between the front glass plate 31 and the transparent electrode 32 is reduced, and the sensitivity of the touch panel is stabilized.
In addition, when the circuit board 35 is replaced in the operation panel 30 as maintenance, only the circuit board 35 can be removed from the operation panel 30 and replaced. That is, it is possible to remove the substrate case member 36 from the reflector member 34 of the operation panel 30 and replace the circuit substrate 35 with respect to the removed substrate case member 36. When the substrate case member 36 is removed from the reflector member 34, the electrical connection between the transparent electrode 32 and the circuit board 35 is released, and the transparent electrode 32 and the circuit board 35 are separated. If the substrate case member 36 after the circuit substrate 35 is replaced is mounted on the reflector member 34 again, only the circuit substrate 35 can be replaced.
As described above, in the operation panel 30, only the circuit substrate 35 may be replaced as maintenance, and in the replacement operation, the front surface glass plate 31 and the transparent electrode 32 are not separated. Therefore, it is possible to prevent foreign matter from being mixed between the front glass plate 31 and the transparent electrode 32 at the time of maintenance, thereby causing a problem that the sensitivity of the touch panel is lowered or no response is made. Further, when the substrate case member 36 is detached from the reflector member 34, most of the back surface side of the front glass plate 31 is covered with the reflector member 34 to the extent that the small holes or openings 341 of the reflector structure are opened, so that it is possible to prevent the fingers of the operator or the like from touching the back surface of the transparent electrode 32 or the front glass plate 31. Therefore, it is possible to prevent fingerprints or attachments from adhering to the back surface of the front glass plate 31 or the transparent electrode 32, and to easily maintain the quality of the touch panel type operation display unit. In addition, when the circuit board 35 is replaced, it is not necessary to replace the transparent electrode 32 and the front glass plate 31 at the same time, which is advantageous in terms of cost.
The embodiments disclosed herein are all examples and are not intended to be interpreted as limiting. Therefore, the technical scope of the present invention is defined not by the description of the above embodiments but by the claims. The scope of the present invention is defined by the claims and all modifications within the scope.
