Description

  The present invention relates to a lid device for a washing machine that opens and closes as a folded lid structure by pivotally supporting front and rear lid bodies on the upper surface of a washing machine body.

  Conventionally, in this type of washing machine lid device, a plurality of lids are pivotally supported with each other to form a folded lid structure, and further, the laundry apparatus is made of a fluoroscopic material for visualizing the movement of clothing during washing. It was provided on the upper surface of the machine main body so as to be opened and closed (see, for example, Patent Document 1).

  FIG. 6 shows a plan view of a lid of a conventional washing machine described in Patent Document 1, and FIG. 7 (a) is a side view of the mating surface side of the rear lid of the washing machine, (b) Is a sectional view of the main part of the rear lid of the washing machine, (c) is a side view of the mating surface side of the front lid of the washing machine, and (d) is a sectional view of the principal part of the front lid of the washing machine.

  As shown in FIG. 6, the opening / closing lid 8 is provided on the upper surface of a washing machine main body (not shown) with one end pivotally supported by a shaft support portion 9 so as to be rotatable upward. The opening / closing lid 8 is composed of two lid bodies 8 a and 8 b that can be folded along the axis 10.

  As shown in FIG. 7 (a), a plurality of support shafts 11a that are cantilevered along the axis 10 are provided at substantially equal intervals at the end of one lid 8a in the lid. As shown in FIG. 7 (c), the other lid body 8b is integrally formed with a bearing portion 12a having the same number of horizontal holes for holding the support shaft 11a at a position corresponding to the support shaft 11a. The shaft support portion 13 of FIG. 6 is formed, and the lid body 8a and the lid body 8b are connected by the shaft support portion 13 to form an opening / closing lid.

  The lid bodies 8a and 8b are made of a transparent material, and a handle portion 14 is provided on the lid body 8b on the front side of the washing machine body, and the lid bodies 8a and 8b are mutually pivoted at positions corresponding to the handle portion 14. It is pivotally supported by the support 13.

  In the above configuration, since the two cover bodies 8a and 8b are mutually centered at substantially the center portion, the support shaft 11a is passed through the bearing portion 12a and is pivotally supported by the shaft support portion 13 to form a folded lid structure. , 8b is slightly warped because the amount of warpage of the substantially central portion of the lids 8a, 8b is small compared to the amount of warpage of the support shaft 11a and the bearing portion 12a as both ends. The lid bodies 8a and 8b can be easily connected to form a folded lid.

  Further, a handle portion 14 of an opaque member is provided at a substantially central portion of the lid body 8b on the front side of the washing machine body, and a shaft support portion 13 that pivotally supports the lid bodies 8a and 8b at a position corresponding to the handle portion 14 is provided. Thus, even when the lids 8a and 8b are made of a material having transparency, it is possible to make it difficult to see the shaft support structure on the back surface of the lid from the front surface, and consideration is given so as not to impair the design.

  In addition, U-shaped opaque decorative plates 23 and 24 are attached to the outer peripheral portions of the transparent material lids 8a and 8b to enhance the strength of the outer peripheral portions of the lids 8a and 8b along with design cooperation. It is said.

Japanese Patent Laid-Open No. 2000-279589

  However, in such a conventional lid configuration, the strength of the lid depends on the strength of the transparent material lids 8a and 8b, and even if the U-shaped decorative plates 23 and 24 are constructed, the lid is particularly opened and closed. The strength in the torsional direction during operation was weak, and there was a problem in productivity, such as increasing the thickness beyond the thickness required for the lids 8a and 8b, and providing a rib for securing strength on the back surface. . In particular, when the handle portion 14 is operated with a strong force, stress is easily applied to the lid body 8a that is pivotally supported by the support portion 9 for rotating one of the grip portions 14, and there is a problem in strength in particular.

  The present invention solves the above-described conventional problems and aims to increase the strength of the lid device.

  In order to achieve the above object, a lid device for a washing machine according to the present invention includes a front lid having a transparent portion configured to be foldable by a pivotal support structure, a rear lid having a transparent portion, and a lid opening / closing configured on the front lid. And a rear lid backing plate disposed on the back surface of the rear lid, the front lid backing plate and the rear lid backing plate are opaque members. The flat cover plate is mounted in the vicinity of the outer periphery of the front cover or the rear cover except the vicinity of the shaft support structure, and the rear cover plate has an opening in the center and is continuous with the periphery of the opening. A rib is formed and attached to the rear surface of the rear lid.

  As a result, the configuration around the rear lid, in particular, increases the rigidity in the torsional direction, and therefore has resistance to an operation with a strong force in the lid opening / closing operation.

  The lid device of the washing machine of the present invention can increase the strength of the lid in the folding lid configuration of the transparent material.

Further, the present invention is not limited by this embodiment.

(Embodiment 1)
FIG. 1 shows a perspective view of a washing machine provided with a lid of the washing machine in Embodiment 1 of the present invention.

  In the perspective view of FIG. 1, a lid 33 is disposed in a substantially central portion of an upper surface cover 32 that covers the upper surface of the washing machine body 31 so as to be freely opened and closed. The lid body 33 is configured such that the front lid body 34 and the rear lid body 35 can be folded at a substantially central portion 36 with a shaft support structure to be described later, and the central portion 34a of the front lid body 34 and the rear lid body 35 The central portion 35a has a transparent structure so that the inside of the washing machine body can be visually recognized.

  Further, a handle portion disposed at a position facing the rear lid body 35 and at a front portion of the front lid body 34 and disposed at a position close to the operation display panel 38 on the front upper portion of the washing machine body 31 of the front lid body 34. By operating 37 upward, the lid can be opened.

  In the perspective view of the washing machine when the lid is opened in FIG. 2, the lid 33 is opened while being bent at the substantially central portion 36 by lifting the handle portion 37 and pushing it backward, and clothes and the like are placed in the washing tub 39 inside. Laundry can be put in and detergent can be put in. In the closed state, the state of the internal washing tub 39 such as the movement of clothing can be visually recognized from the central portion 34a of the transparent structure.

  The reason why the lid 33 is foldable with a pivotal support structure is that when the lid 33 is opened to increase the size of the lid 33 so that clothes can be easily put in and taken out. Then, in order to avoid that the height at the time of opening becomes high too much and to reduce operativity, and to avoid interference with other members in the space above the washing machine installation place.

  In the external perspective view of the lid of FIG. 3, the front lid body 34 has a handle portion 37 and is made of a transparent material having a substantially semicircular front lid 40 and an opaque member attached from the back surface of the front lid 40. The rear lid body 35 is configured by a substantially horseshoe-shaped front lid plate 41, and is mounted from the rear surface of the rear lid 42 and a rear surface of the rear lid 42, and has an opening 43 in the center. Is constituted by a rear cover plate 44 that approximates the shape of the rear cover 42.

  Further, the outer peripheries of the front lid 40 and the rear lid 42 are constituted by substantially meshed portions B and C, which increase the rigidity of the front lid body 34 and the rear lid body 35 (details will be described later with reference to FIG. 5). ).

  The rear abutting plate 44 has a shaft support structure (described later in FIG. 4) that supports the folding of the lid at a substantially central portion 36, and a rear lid 35 that can be freely opened and closed on the top panel of the washing machine body. A pivoting support portion 55 to be supported is configured.

  Members such as the front lid 40, the front lid plate 41 and the rear lid 42, and the rear lid plate 44 of the front lid 40 are adaptable to complex shapes, can be adapted to a variety of designs, and have a high productivity. High plastic molded products are often used.

  In the cross-sectional view of the lid of FIG. 4, the contents constituting the folding lid of the pivot support structure 53 in which the front lid 40 and the rear lid 42 are pivotally supported are described.

  A plurality of bearing ribs 47 having a through hole bearing portion 46 are integrally formed on the front lid 40 behind the rear wall 50, while the rear lid backing plate 44 mounted from the lower back side of the rear lid 42 includes: A support shaft rib 49 having a support shaft 45 is integrally formed at a position corresponding to the bearing portion 46 of the front lid 40.

  The support shaft 45 is attached to the bearing portion 46 so that the front lid 40 and the rear lid 42 are rotatable, and a shaft support structure 53 is configured.

  Since the bearing portion 46 and the bearing rib 47 of the front lid 40 extend to a position protruding rearward of the rear wall 50 of the front lid 40, the arrangement of the support shaft 45 and the support shaft rib 49 of the rear lid pad 44 is as follows. In addition, it is arranged substantially below the shielding rib 52 extending toward the opening 43 side. Therefore, when the lid 33 is closed, the bearing portion 46, the support shaft 45, the support shaft rib 49, and the like are difficult to see when the inside of the tank is visually confirmed through the transparent material from above and obliquely forward, which is a state often viewed by the user. Thus, the design in the state where the lid 33 is closed is improved.

  In the exploded perspective view of the lid in FIG. 5, the rear lid 42 on the flat plate having a transparent material and a substantially trapezoidal shape is fitted with an opaque rear lid backing plate 44 from the back surface, and the rear lid backing plate 44 is centered. The lower part can be seen through through the opening 43 provided in.

  Further, the outer shape of the rear lid abutting plate 44 is approximated to the outer shape of the rear lid 42, and on the inner side, on the periphery of the opening 43, the plate-shaped shielding rib 52 on the support shaft 45 side and the rotation support portion 55 side. The plate-shaped rear rib 54 and the left and right plate-shaped connecting ribs 56a and 56b connecting the shielding rib 52 and the rear rib 54 form a planar rib.

  Further, a large number of curved convex ribs 57 are integrally formed on the upper surfaces of the connecting ribs 56a and 56b of the rear lid abutting plate 44, that is, on the surface on the rear lid 42 side so as to vortex in appearance.

  The spiral direction of the convex ribs 57 on the upper surface side of the rear lid abutting plate 44 is a spiral A having a twist in the counterclockwise direction when viewed from above the rear lid 42.

  On the other hand, on the back surface of the rear lid 42 (on the rear lid abutting plate 44 side), a curved shape having a twist in a direction opposite to the spiral A when viewed from above the rear lid 42, that is, in a clockwise spiral B direction. A large number of convex ribs 58 are provided and integrally formed, and are configured to abut on the convex ribs 57 on the rear lid abutting plate 44 side.

  Therefore, when the rear lid abutting plate 44 is attached to the rear lid 42, the convex ribs 58 in the direction of the spiral B on the back surface of the transparent lid 42 and the upper surface on the rear lid abutting plate 44 side are formed. The convex ribs 57 in the spiral A direction are overlapped and crossed to form a meshed state that can be viewed from the upper surface of the transparent lid 42 (the meshed portion C shown in FIG. 3).

  On the other hand, the front lid 40 having a transparent material with a handle portion 37 formed in the front and having a substantially semicircular planar shape is located below the central portion excluding an opaque substantially horseshoe-shaped front lid pad 41 attached from the back side. I can see through.

  Similarly, spiral convex ribs are formed on the front lid 40 and the front lid plate 41.

  That is, a convex rib 59 having a twist in the same spiral B direction as that of the rear lid 42 is integrally formed on the rear surface of the front lid 40 (front lid backing plate 41 side). A large number of spiral A convex ribs 60 are integrally formed on the surface of the front lid abutting plate 41 along a horseshoe shape, and are in contact with the convex ribs 59 on the front lid 40 side.

  Therefore, when the front cover plate 41 is attached to the front cover 40, the convex rib 59 in the direction of the spiral B on the back surface of the front cover 40 made of transparent material and the upper surface on the front cover plate 41 side. The formed convex ribs 60 in the spiral A direction overlap and can be visually recognized as a crossed mesh state (portion B in the mesh state shown in FIG. 3).

  Although not shown, the front lid 40, the front lid plate 41, the rear lid 42, and the rear lid plate 44 are mounted by general processing such as welding, adhesion, fitting, and fitting.

  The rear lid abutting plate 44 has an opening 43 in the center, and the peripheral edge of the opening is connected by a flat plate rib that is continuous with a shielding rib 52 and a rear rib 54 on the flat plate and connecting ribs 56a and 56b on the left and right. Since it is attached to the rear lid 42 in a beam configuration, the rigidity in the torsional direction of the rear lid body 35 can be enhanced, so that it is possible to withstand operation by a strong force in the lid opening / closing operation. is there.

  Further, the front lid 40 and the front lid abutting plate 41, and the rear lid 42 and the rear lid abutting plate 44 are provided with a convex rib 60 and a convex rib 57 having an inclination in the opposite direction to the convex rib 59 at the outer periphery. By forming convex ribs 58 having an inclination in the opposite direction and attaching them to each other, it is possible to provide strength without forming the plate thickness in the molding process of the lid by forming the convex ribs. It is excellent in productivity, such as being able to visually recognize a crossed mesh state having a profound feeling visually from the lid surface.

  Moreover, the convex ribs 57, 58, 59, 60 can obtain the same effect even if they are not curved but linear.

  As described above, since the lid device of the washing machine according to the present invention can increase the rigidity of the folding lid of the transparent member, it is also useful as a lid for household appliances with various opening and closing operations. .
