Description

Embodiments of the present invention relate to washing machines.

For example, as disclosed in Patent Document 1, a washing machine in which a flat glass surface material is provided on a lid for opening and closing an opening for entering and exiting laundry provided in the washing machine main body is considered. According to a washing machine having a glass surface material on a lid that is easily visible to the user, it is possible to improve the design of the washing machine as a whole.

Japanese Patent No. 4719433

However, the conventional washing machine has a configuration in which a glass surface material is attached to a resin member constituting the main body of the lid with a double-sided adhesive tape. That is, a glass surface material having a thermal deformation rate different from that of the resin member is attached to the resin member. Therefore, due to the difference in the thermal deformation rates of both members, both members are deformed by different amounts of deformation due to temperature changes at the installation location of the washing machine and temperature changes due to operating conditions. When the resin member and the glass surface material constituting the lid are deformed by different amounts of deformation, a large shearing force is generated on the adhesive surface of the double-sided adhesive tape that attaches both members, and the glass surface material is released from the resin member. It will peel off. The thermal deformation includes both the contraction of the member due to heat and the expansion of the member due to heat.

Therefore, in a configuration in which a planar member having a thermal deformation rate different from that of the resin member is attached to the resin member constituting the main body of the lid with a double-sided adhesive tape, it is possible to prevent the planar member from peeling off from the resin member. Provide a washing machine that can.

The washing machine according to the present embodiment includes a washing machine main body, an opening for entering and exiting laundry, a lid, a resin member, a planar member, and a double-sided adhesive tape. An opening for entering and exiting the laundry is provided in the washing machine body. The lid opens and closes the opening. The resin member constitutes the main body of the lid. The planar member has a thermal deformation rate different from that of the resin member. The double-sided adhesive tape attaches a planar member to a resin member. The resin member is provided with a reinforcing rib at a central portion for keeping the resin member flat, and is not provided with the reinforcing rib at an end portion other than the central portion. The double-sided adhesive tape is provided with a deformable portion and an adhesive portion provided on both sides of the deformable portion and having adhesiveness, and is provided at the end portion of the lid not provided with the reinforcing rib. It is arranged in a portion where the resin member and the planar member face each other .

Hereinafter, an embodiment relating to the washing machine will be described with reference to the drawings. The washing machine 1 illustrated in FIGS. 1 to 3 is a so-called vertical axis type washing machine in which the rotation axis of the washing tub is in the vertical direction, and a rectangular plate-shaped lid 3 is provided on the upper part of the washing machine main body 2. The width of the lid 3 in the left-right direction is substantially the same as the width of the washing machine main body 2 in the left-right direction. In the following, "almost the same size" includes a case where the two dimensions are completely the same, and also includes a case where the two dimensions are slightly different so as to be regarded as the same.

The washing machine main body 2 includes, for example, a rectangular box-shaped outer box 4 made of steel plate, and a top cover 5 made of, for example, synthetic resin. The top cover 5 is provided on the upper part of the outer box 4. That is, the top cover 5 constitutes the upper part of the washing machine main body 2. Inside the outer box 4, a water tank (not shown) for storing washing water is elastically supported by an elastic suspension mechanism. Then, as illustrated in FIG. 2, a washing tub 6 for accommodating laundry is rotatably provided inside the water tub. The rotation axis of the washing tub 6 is a vertical axis extending in the vertical direction of the washing machine main body 2.

The top cover 5 has a thin hollow box shape in which the lower surface is open and the upper surface is inclined downward toward the front. At the center of the top cover 5, an opening 7 for entering and exiting laundry is provided above the washing tub 6. The opening 7 opens in an arc shape on the front side and in a rectangular shape on the rear side. The front surface portion and the side surface portion of the opening portion 7 are inclined toward the inside of the opening portion 7 toward the lower side, so that the opening portion 7 has a smaller opening area toward the lower side. Further, the opening 7 is a wall portion whose rear surface portion is vertical. A detergent case 8 into which detergents are put is provided at the center of the rear surface of the opening 7 in the left-right direction. The detergent case 8 is provided so that it can be taken in and out along the front-rear direction of the washing machine 1. In this case, as illustrated in FIG. 3, the upper surface of the top cover 5 is inclined downward toward the front. Therefore, the depth of the opening 7 is deeper on the rear side than on the front side.

The lid 3 that opens and closes the opening 7 is provided on the upper surface of the top cover 5 so as to be rotatable in the front-rear direction. As will be described later, the upper surface of the top cover 5 is formed in a flat shape without steps. A rotating shaft portion 9 extending in the left-right direction is provided at the base end portion of the lid 3. The rotating shaft portion 9 rotatably supports the lid 3 with respect to the washing machine main body 2. The rotating shaft portion 9 has a substantially cylindrical shape extending in the left-right direction of the lid 3 at the base end portion of the lid 3.

On the other hand, a recess 10 extending in the left-right direction of the top cover 5 is provided in a portion of the upper portion of the top cover 5 directly above the rear surface portion of the opening 7. The recess 10 has a shape recessed in an arc shape in cross section so as to correspond to the shape of the cylindrical rotating shaft portion 9. The width of the recess 10 in the left-right direction is substantially the same as the width of the top cover 5 in the left-right direction, in other words, the width of the washing machine main body 2 in the left-right direction. Therefore, both ends of the recess 10 in the left-right direction are not closed, and the recess 10 is exposed toward the side of the washing machine main body 2. Then, the rotating shaft portion 9 of the lid 3 is housed in the recess 10 on the washing machine main body 2 side. As a result, the lid 3 is rotatably supported on the upper part of the washing machine main body 2.

A lid support portion 11 for supporting the lid 3 with the opening 7 closed is provided on the upper portion of the top cover 5, in other words, the upper portion of the washing machine main body 2. The lid support portion 11 is provided in a flat shape around the opening 7. In this case, the lid support portion 11 is formed so as to surround the periphery of the opening 7 except for the front end portion of the opening 7.

Further, an operation panel 12 for inputting various operations to the washing machine 1 is provided on the upper part of the front part of the top cover 5, in other words, the upper part of the front part of the washing machine main body 2. The operation panel 12 is provided at the front portion of the lid support portion 11 so as to be continuous with the lid support portion 11. The upper surface of the lid support portion 11 and the upper surface of the operation panel 12 are flush with each other. As a result, the periphery of the opening 7 is surrounded by a continuous flat surface portion having no step, which is composed of the upper surface of the lid support portion 11 and the upper surface of the operation panel 12. In the central portion of the rear portion of the operation panel 12, a recess portion 13 that is recessed in an arc shape along the opening shape on the front side of the opening portion 7 is provided.

As illustrated in FIGS. 4 and 5, the lid 3 has a so-called two-fold structure, and includes a main body portion 21 and a tip portion 22. The main body 21 of the lid 3 is configured to include a resin member 23 and a planar member 24. The resin member 23 is a member that constitutes the back surface side portion of the lid 3, and is made of, for example, a crystalline synthetic resin material having high chemical resistance and strength. The crystalline resin material is, for example, polypropylene resin, polyethylene resin, polyethylene terephthalate resin, polyacetal resin, or the like. The resin member 23 constitutes the back surface of the main body 21 of the lid 3, that is, the surface on the opening 7 side. The back surface of the main body 21 of the lid 3 is the lower surface when the lid 3 is closed with the opening 7 as illustrated in FIGS. 1 and 3, and the lid 3 is the opening as illustrated in FIG. This is the front surface when the 7 is opened.

Inclined surface portions 23a are provided at both ends of the resin member 23 in the left-right direction. The inclined surface portion 23a constitutes both ends of the main body portion 21 of the lid 3 in the left-right direction. Since the inclined surface portion 23a is inclined, both ends of the main body portion 21 of the lid 3 in the left-right direction are in a so-called chamfered state. Further, on the tip end side of the resin member 23, a tip end support portion 23b for rotatably supporting the tip end 22 is provided. Further, as illustrated in FIG. 6, a plurality of reinforcing ribs 52 for keeping the resin member 23 flat are provided in the central portion 51 of the resin member 23. Further, the end portion 53 of the resin member 23 excluding the central portion 51 is formed in a flat shape.

The planar member 24 is a member that constitutes the surface side portion of the lid 3, and is formed of, for example, a hard glass plate having a thickness of about 5 mm and has a rectangular thin plate shape. The planar member 24 may be colored or transparent. When the planar member 24 constituting the surface side portion of the lid 3 is fixed by a fixing member such as a screw, the fixing member becomes conspicuous on the surface of the lid 3 and spoils the aesthetic appearance. Therefore, the planar member 24 is attached to the upper surface of the resin member 23 via a plurality of, in this case, four double-sided adhesive tapes 26. The double-sided adhesive tape 26 is arranged at an end portion 53 on the upper surface of the resin member 23 constituting the lid 3 at a portion where the resin member 23 and the planar member 24 face each other. That is, the double-sided adhesive tape 26 is arranged so as to intermittently form a rectangular shape so as to surround the central portion 51 of the resin member 23 provided with the reinforcing rib 52.

Then, the tip end portion of the planar member 24 attached to the resin member 23 via the resin member 23 is suppressed by the pressing member 27. The width of the holding member 27 in the left-right direction is substantially the same as the width of the main body portion 21 in the left-right direction. The planar member 24 constitutes the surface of the main body 21 of the lid 3. The surface of the main body 21 of the lid 3 is an upper surface when the lid 3 closes the opening 7 as illustrated in FIGS. 1 and 3, and the lid 3 has an opening as illustrated in FIG. This is the rear surface when the 7 is opened.

The tip portion 22 of the lid 3 has a rectangular plate shape smaller than that of the main body portion 21. The width of the tip portion 22 of the lid 3 in the left-right direction is substantially the same as the width of the main body portion 21 of the lid 3 in the left-right direction. The tip portion 22 of the lid 3 includes a back surface side member 31 and a front surface side member 32. The back surface side member 31 is made of, for example, a crystalline synthetic resin material, like the resin member 23 of the main body portion 21. Inclined surface portions 31a are provided at both ends of the back surface side member 31 in the left-right direction. The inclined surface portion 31a constitutes both ends in the left-right direction of the tip portion 22 of the lid 3. Since the inclined surface portion 31a is inclined, both ends of the tip portion 22 of the lid 3 in the left-right direction are in a so-called chamfered state.

The surface side member 32 is made of, for example, a synthetic resin material. The synthetic resin material constituting the surface side member 32 may be a crystalline synthetic resin material or other synthetic resin material. Further, the surface side member 32 is provided with a handle portion 33 for hooking a finger when the user opens and closes the lid 3.

The tip portion 22 of the lid 3 has a configuration in which the back surface side member 31 and the front surface side member 32 are combined. The base end portion of the tip portion 22 of the lid 3 is rotatably supported by the tip end portion support portion 23b of the main body portion 21. The back surface side member 31 of the lid 3 constitutes the back surface of the tip end portion 22 of the lid 3, that is, the surface on the opening 7 side. The back surface of the tip portion 22 of the lid 3 is a lower surface when the lid 3 closes the opening 7 as illustrated in FIGS. 1 and 3, and the lid 3 has an opening as illustrated in FIG. In the open state where 7 is opened, it is a surface facing the back surface of the main body 21.

That is, in this case, the lid 3 has a so-called foldable lid structure composed of two independent portions, a main body portion 21 and a tip portion 22. Therefore, in the closed state in which the lid 3 closes the opening 7, as illustrated in FIGS. 1 and 3, the main body 21 and the tip 22 of the lid 3 are in a flush plate state, and the opening 7 is in this state. Close. On the other hand, in the open state in which the lid 3 opens the opening 7, as illustrated in FIG. 2, the main body 21 of the lid 3 stands substantially in the vertical direction on the recess 10, and the tip 22 of the lid 3 Is in a state of being folded downward from the upper end of the main body portion 21. That is, the lid 3 is in a state in which the resin member 23 of the main body 21 and the back surface side member 31 of the tip 22 face each other.

As illustrated in FIG. 5, a convex portion 41 is provided on the back surface of the lid 3. The convex portion 41 has an arcuate shape on the tip end side, which is the tip end portion 22 side, and a substantially rectangular shape on the base end side, which is the main body portion 21, corresponding to the opening shape of the opening portion 7. When the lid 3 closes the opening 7, the convex portion 41 fits into the opening 7. As a result, sound leakage from the inside of the washing machine main body 2 can be prevented, and foreign matter such as dust can be prevented from entering the inside of the washing machine main body 2 from the opening 7.

Next, a configuration example of the double-sided adhesive tape 26 will be described. As illustrated in FIG. 7, the double-sided adhesive tape 26 includes a deformable deformable portion 26a and an adhesive adhesive portion 26b provided on both sides of the deformable portion 26a. The deformable portion 26a is made of a foamable resin material such as acrylic foam, has elasticity and elasticity, and can be deformed when an external force is applied. Further, the deformable portion 26a made of such a foamable resin material has a certain thickness and also has cushioning properties. The adhesive portion 26b is made of, for example, an acrylic adhesive.

According to the washing machine 1 according to the present embodiment, in a configuration in which a planar member 24 having a thermal deformation rate different from that of the resin member 23 is attached to the resin member 23 constituting the main body 21 of the lid 3 with a double-sided adhesive tape 26. The double-sided adhesive tape 26 is configured to include adhesive portions 26b on both sides of the deformable deformable portion 26a. Therefore, even if a large shearing force is generated on the adhesive surface of the double-sided adhesive tape 26 due to the difference in the thermal deformation rate between the resin member 23 and the planar member 24, the action can be absorbed by the deformable deformable portion 26a. This makes it possible to prevent the planar member 24 from peeling off from the resin member 23.

Further, according to the washing machine 1, since the deformable portion 26a is made of a foamable resin material, it has a high deformability with respect to an external force. Therefore, when a large shearing force is generated on the adhesive surface of the double-sided adhesive tape 26 due to the difference in the thermal deformation rate between the resin member 23 and the planar member 24, the shearing force can be sufficiently absorbed from the resin member 23. It is possible to further prevent the planar member 24 from peeling off.

Further, according to the washing machine 1, since the resin member 23 is made of a crystalline resin material, for example, it has high chemical resistance and strength. Therefore, it is possible to prevent solvent cracks, so-called solvent cracks, from occurring in the main body 21 of the lid 3. Further, it is possible to realize a main body portion 21 having high strength, and to realize a structure that is strong against an impact when opening and closing the lid 3.

Further, according to the washing machine 1, the double-sided adhesive tape 26 is arranged at a portion of the end portion 53 of the main body portion 21 of the lid 3 where the resin member 23 and the planar member 24 face each other. That is, since the planar member 24 can be firmly attached to the resin member 23 without arranging the double-sided adhesive tape 26 in the central portion 51 of the main body portion 21 of the lid 3, the central portion 51 of the main body portion 21 can be firmly attached. For example, the reinforcing rib 52 can be provided.

As illustrated in FIG. 8, an opening 61 penetrating the resin member 23 is provided in the central portion 51 of the resin member 23, and the planar member 24 is all or one of the portions facing the opening 61. A transparent portion 62 may be provided in the portion. According to this configuration, the user can check the inside of the washing machine 1, that is, the inside of the washing tub 6 through the transparent portion 62 provided on the lid 3.

The washing machine 1 may be configured to include a single rectangular plate-shaped lid instead of the so-called two-fold type lid 3. Also in this case, by sticking the planar member to the resin member constituting the main body of the lid with the double-sided adhesive tape 26, it is possible to prevent the planar member from peeling off from the resin member. In the so-called two-fold type lid 3 provided with the main body portion 21 and the tip portion 22, the double-sided adhesive tape 26 is not arranged at the end portion of the lid 3 as a whole. In the two-fold type lid 3, the double-sided adhesive tape 26 is arranged at the end of the main body 21 of the lid 3 to which the planar member 24 is attached. That is, the "end of the lid" in the present embodiment can be defined as the end of the portion of the lid to which the planar member is attached.

Further, the surface member 24 may be formed of a member whose lid surface is made of, for example, a resin material such as acrylic or a metal material such as stainless steel, instead of a glass plate material. Acrylic is a material having a slightly lower thermal deformation rate than the resin member 23, while glass and stainless steel are materials having a lower thermal deformation rate than acrylic. Further, the resin material constituting the resin member 23 is a material having a relatively high thermal deformation rate, at least a material having a higher thermal deformation rate than the material constituting the planar member 24. Further, the foamable deformable portion 26a constituting the double-sided adhesive tape 26 may be made of, for example, urethane foam or polyethylene foam.

Further, the double-sided adhesive tape 26 may be provided only on the left-right end 53 or the front-rear end 53 of the resin member 23. Further, the double-sided adhesive tape 26 may have a single frame-like structure surrounding the central portion 51 of the resin member 23. That is, the arrangement mode of the double-sided adhesive tape 26 can be appropriately changed as long as it can prevent the planar member 24 from peeling off from the resin member 23.

According to the washing machine according to the present embodiment, in a configuration in which a planar member having a thermal deformation rate different from that of the resin member is attached to the resin member constituting the main body of the lid with the double-sided adhesive tape, the double-sided adhesive tape is deformed. Adhesive parts are provided on both sides of the possible deformable parts. According to this configuration, the shearing force acting on the adhesive surface of the double-sided adhesive tape can be absorbed by the deformable portion due to the difference in the thermal deformation rate between the resin member and the planar member, and the planar member is peeled off from the resin member. It is possible to avoid the problem.
