  Embodiments of the present invention will be described below with reference to the drawings. In the following drawings, the vertical and horizontal directions of the washing machine are indicated by arrows as appropriate.

1 and 2 are perspective views of the washing machine of this embodiment. A top cover 4 and an opening / closing lid 1 are provided on the upper portion of the washing machine 2 to cover the washing tub 3. That is, as shown in FIG. 1, a rear panel 11 is provided at the rearmost part of the upper part of the washing machine 2, and an operation panel 12 is provided at the foremost part of the upper part of the washing machine 2. The opening / closing lid 1 is provided between the rear panel 11 and the operation panel 12. The opening / closing lid 1 can be folded in half as shown in FIG. 2, and the upper part of the washing tub 3 is exposed by opening. The opening / closing lid 1 includes a rear opening / closing lid 31 constituting the washing machine rear side of the opening / closing lid 1 and a front opening / closing lid 41 constituting the washing machine front side of the opening / closing lid 1. A glass plate 34 is provided on the upper surface of the rear opening / closing lid 31.
A pair of hinge portions (first hinge portions) 22 are provided at the base end portion 21 on the rear side of the opening / closing lid 1, and the opening / closing lid 1 is supported by the hinge portion 22 on the upper rear side of the washing machine 2. ing.

  3 is a top view of the washing machine of the present embodiment, FIG. 4 is an AA longitudinal sectional view of FIG. 3, (a) is an overall view, and (b) is an enlarged view of a portion B of (a). FIG. 4C is an enlarged view of a C portion. As shown in FIG. 2, the rear opening / closing lid 31 and the front opening / closing lid 41 are connected by a hinge mechanism, which will be described later, and the rear opening / closing lid 31 is lifted upward and the front opening / closing lid 41 is bent forward and downward. Can be folded.

By the way, in such an openable lid 1 that can be folded in two, it is conceivable to form a glass plate on the surface in order to enhance the design. And considering the design, I want to make the glass plate look as big as possible. Therefore, it is conceivable to form a glass plate on each of the rear opening / closing lid 31 and the front opening / closing lid 41 to make the entire glass plate look larger.
However, when the glass plate is formed and the entire glass plate is enlarged, when the dryer 102 (see FIG. 6) is installed on the upper part of the washing machine 2, there is a problem that the opening / closing lid 1 hits the dryer 102.
Therefore, the technical contents of the present embodiment for solving such problems and other problems will be described below.

As shown in FIGS. 3 and 4, the rear opening / closing lid 31 includes a main body panel 32 made of, for example, resin. A glass support portion 33 is formed on the upper surface of the main body panel 32. That is, a single glass plate 34 is provided on the upper surface of the main body panel 32, and the glass plate 34 is supported on the glass support portion 33. A hook-shaped locking portion 35 is provided on the entire front edge portion of the rear opening / closing lid 31, and the distal end portion of the locking portion 35 faces the rear side. Similarly, a hook-shaped locking portion 36 is provided on the entire rear edge portion of the rear opening / closing lid 31, and the leading end of the locking portion 36 faces the front side. That is, the latching portion 35 latches the front edge portion 34a of the glass plate 34, and the latching portion 36 latches the rear edge portion 34b of the glass plate 34, thereby fixing the glass plate 34 to the main body panel 32. It is fixed to.
A handle 42 for opening and closing the opening / closing lid 1 is provided at a position near the rear opening / closing lid 31 at the center in the left-right direction of the front opening / closing lid 41.

  In order to enhance the design, the boundary 43 between the rear opening / closing lid 31 and the front opening / closing lid 41 has a gentle arc shape in which the central portion in the left-right direction swells forward. That is, the front edge portion of the rear opening / closing lid 31 has a gentle arc shape such that the central portion in the left-right direction swells forward. Moreover, the edge part of the rear side of the front opening / closing lid 41 has a gentle arc shape in which the central part in the left-right direction is recessed forward. Then, the shape of the front edge portion of the rear opening / closing lid 31 and the shape of the edge portion of the rear side of the front opening / closing lid 41 are matched as shown in FIG. 3 with the opening / closing lid 1 closed.

As shown in FIG. 3, the length L1 of the rear opening / closing lid 31 out of the length L of the opening / closing lid 1 as viewed from the front exceeds half, more desirably more than one third. The length L2 of the front opening / closing lid 41 is shortened. In the example of FIG. 3, the length L1 is about three quarters of the length L, but this is only an example.
In addition, the code | symbol which is not demonstrated in FIG. 4 is mentioned later.

  FIG. 5 is an exploded perspective view of the opening / closing lid 1. Overhanging portions 52 and 53 project to the front side at both ends in the left-right direction of the front edge 51 of the rear opening / closing lid 31, respectively. Cylindrical support shafts 52a and 53a are provided on the overhang portions 52 and 53, respectively, with the axial direction being the left-right direction, the tip portions thereof being provided with the support shaft 52a on the right side and the support shaft 53a on the left side.

  A blocking member 54 projects from the end edge 51 toward the front side (front opening / closing lid 41 side) at the center in the left-right direction at the front edge 51 of the rear opening / closing lid 31. The blocking member 54 has a cylindrical shape in which the portion protruding from the edge 51 has a longitudinal direction in the left-right direction (FIG. 4B), and the user holds the hand on the handle 42 by forming the cylindrical shape. It is prevented that a finger is inserted when trying to close the opening / closing lid 1 by hanging. Support shafts 54a and 54b are provided at both ends in the left-right direction of the blocking member 54, with the axial direction being the left-right direction. The blocking member 54 is not limited to a cylindrical shape, and may be a polygonal cylinder shape such as an octagonal cylinder as long as it prevents the user's finger from being inserted.

  The front opening / closing lid 41 includes an upper panel 61 and a lower panel 62. Notch portions 63 and 64 into which the overhang portions 52 and 53 are respectively inserted are provided at both left and right end portions on the rear side of the lower panel 62. Bearing portions 63a and 64a for bearing the support shafts 52a and 53a are provided in the notches 63 and 64, respectively. A notch 65 into which the blocking member 54 is inserted is provided at the center in the left-right direction on the rear side of the lower panel 62. Bearing portions 65a and 65b for bearing the support shafts 54a and 54b are provided at the left and right ends of the notch 65, respectively.

  Although not shown in FIG. 5, on the lower surface of the upper panel 61, bearing portions similar to the respective bearing portions are formed at positions corresponding to the bearing portions 63a, 64a, 65a, and 65b, respectively. When the upper panel 61 and the lower panel 62 are fixed by screwing or the like, they are supported by the bearing portions 63a, 64a, 65a, 65b of the lower panel 62 and the corresponding bearing portions of the upper panel 61. The shafts 52a, 53a, 54a, and 54b are respectively bearings.

In the present embodiment, with such a configuration, the rear opening / closing lid 31 and the front opening / closing lid 41 are connected, and the rear opening / closing lid 31 and the front opening / closing lid 41 allow the opening / closing lid 1 to be folded in two. The structure (second hinge part) is realized.
That is, the front opening / closing lid 41 can be rotated downward with respect to the rear opening / closing lid 31 by this hinge structure. Further, as shown in FIG. 4B, the rear edge 66 of the upper panel 61 is in contact with the front edge 51 of the rear opening / closing lid 31. The opening / closing lid 41 cannot be rotated upward beyond a certain level.

Further, as shown in FIG. 5, the blocking member 54 is provided at the center in the left-right direction of the front edge 51 of the rear opening / closing lid 31. The handle 42 is provided at the center in the left-right direction on the rear side of the front opening / closing lid 41. Therefore, the blocking member 54 is located in the vicinity of the handle 42.
FIG. 6 is a side view of the washing machine 2. A stand 101 is attached to the washing machine 2, and a dryer 102 is attached on the stand 101. FIG. 6 shows a state in which the opening / closing lid 1 is folded in half and opened.

  As shown in FIG. 3, the length L1 of the rear opening / closing lid 31 out of the length L of the opening / closing lid 1 viewed from the front exceeds half of that, and the length L2 of the front opening / closing lid 41 is accordingly It is getting shorter. In this way, the length L1 of the rear opening / closing lid 31 is increased. However, as shown in FIG. 6, when the opening / closing lid 1 is folded in two, the tip of the rear opening / closing lid 31 is provided at the top of the washing machine 2. The length of the dryer 102 or the stand 101 supporting the dryer 102 is not reached (when the tip of the rear opening / closing lid 31 is at the highest position). That is, the length L1 of the rear opening / closing lid 31 is made as long as possible as long as the rear opening / closing lid 31 does not hit the dryer 102 or the stand 101.

  Thereby, the surface of the rear opening / closing lid 31 can be made as wide as possible. Therefore, it becomes possible to make the single glass plate 34 provided on the surface of the rear opening / closing lid 31 as wide as possible and to improve the design. Further, the stand 101 can be configured to be height adjustable in a plurality of stages (for example, three stages). In this case, the length L1 of the rear opening / closing lid 31 is made as long as possible so that the rear opening / closing lid 31 does not come into contact with the dryer 102 or the stand 101 when the stand 101 is installed at the highest height where it can be installed. Thus, the single glass plate 34 provided on the surface of the rear opening / closing lid 31 can be widened as much as possible, and the design can be improved.

FIG. 7 shows the rear opening / closing lid 31 in a state where the opening / closing lid 1 is folded in half. FIG. 7A is a plan view, and FIG. 7B is a front view of the front opening / closing lid 41. 8 is a longitudinal sectional view taken along the line DD of FIG. 7A, FIG. 8A is an overall view, and FIG. 8B is an enlarged view of a portion E in FIG.
As shown in FIGS. 7 and 8, when the opening / closing lid 1 is folded in half, a gap 71 between the front opening / closing lid 41 and the rear opening / closing lid 31 is formed in the vicinity of the handle 42. When the user puts his hand on the handle 42 and tries to close the open / close lid 1, his / her finger may be inserted into the gap 71.

On the other hand, the blocking member 54 extends forward from the front edge 51 of the rear opening / closing lid 31, and closes the gap 71 as shown in FIG. Therefore, the blocking member 54 can block the insertion of a finger in the vicinity of the handle 42 between the rear opening / closing lid 31 and the front opening / closing lid 41.
Further, since the blocking member 54 closes the gap 71 and the blocking member 54 can be easily wiped and cleaned, the cleanability of the open / close lid 1 can be improved.

Furthermore, since the locking portions 35 and 36 shown in FIGS. 4B and 4C are bowl-shaped and integrated with the main body panel 32, the main body panel 32 is attached using a general mold. Molding makes it difficult to remove the locking portions 35 and 36.
Therefore, in order to mold the main body panel 32 with a mold, the mold part for molding the inside of the hook part of the locking portions 35 and 36 is separated from the mold for molding the other part, and the former is the latter. By adopting a slide mold structure that can be slid and removed from the mold, it is easy to mold the locking portions 35 and 36.

  Further, the blocking member 54 is not provided along the entire circumference of the locking portion 35, but is provided only along a part of the circumference including the central portion of the locking portion 35. This is because the locking portion 35 is not a linear shape, but has a substantially arc shape in order to ensure designability, while the blocking member 54 has a linear shape from the viewpoint of cost and the like. Thereby, while improving designability, insertion of a user's finger | toe can be blocked | prevented.

  Next, in the present embodiment, as described above, the glass plate 34 is formed on the opening / closing lid 1 in order to improve the design, so that the weight is heavier than the conventional opening / closing lid. Therefore, in order to prevent the lid from collapsing when used by a customer, an engagement shape is provided between the opening / closing lid 1 and the top cover 4, and the lid is fixed as a stopper at the engagement portion when the lid is collapsed.

  FIG. 9 shows a schematic view of the opening / closing lid. (A) is an enlarged view of G part, (b) shows a FF cut longitudinal cross-sectional view. An engaging member 32 is attached between the rear opening / closing lid 31 and the locking portion 36. When an external force is applied from the P direction, the elastic member 33 sandwiched between the engaging member 32 and the rear opening / closing lid 31 expands and contracts, so that the engaging member 32 expands and contracts in the H direction.

  FIG. 2 shows a state in which the lid 1 is attached to the main body and the state in which the opening / closing lid 1 is opened. FIG. 10 shows an enlarged view of a portion J in FIG. The top cover 4 is provided with an engagement portion 4a that engages with the opening / closing lid 1, and the engagement portion 4a engages with the engagement member 32 of the opening / closing lid so that the lid becomes a stopper and is fixed. It has become. FIG. 11 shows a state in which the opening / closing lid 1 is fixed by a stopper.

  The engagement structure is shown in FIG. FIG. 12A shows a longitudinal sectional view taken along the line KK of FIG. FIG.12 (b) shows the said shape part at the time of engagement. When the opening / closing lid is fully opened, the engaging member 32 provided on the opening / closing lid is pushed in the H direction by the elastic body 33. Here, the engaging member 32 has a first substantially convex shape, and the top cover engaging portion 4a has a second substantially convex shape. The first substantially convex shape of the engaging member 32 is also pushed in the H direction by the elastic body 33 (FIG. 12A). When the opening / closing lid is closed from this state, the first substantially convex shape of the engaging member 32 comes into contact with the second substantially convex shape of the top cover engaging portion 4a. At this time, the direction opposite to the H direction Thus, the first substantially convex shape of the engaging member 32 is pushed (FIG. 12B). Thus, the engaging member 32 has the first substantially convex shape abuts on the second substantially convex shape of the top cover engaging portion 4a, and the repulsive force of the elastic body 33 causes the engaging member 32 to engage with the top cover. The opening / closing lid 1 is fixed by engaging with the portion 4a.

With this structure, the lid can be prevented from falling down suddenly, and even if a heavy material is used for the lid, it can be used safely.
In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described 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.
