Description

The present disclosure relates to a washing machine for washing laundry.

The vertical washing machine has an opening formed on the upper surface of the housing, and the lid is opened to allow laundry to enter and exit the opening.

In recent years, there has been a tendency for a washing machine having a flat design that uses a glass material as a member constituting the surface of the lid to be preferred. By adopting the glass material, the weight of the lid is heavier than that of the lid made of conventional resin parts.

Therefore, consideration must be given to operability when opening and closing the lid, and a torsion spring is placed at the hinge of the lid to urge the lid in the opening direction to reduce the speed at which the lid is opened and closed. Can be considered.

However, by disposing the torsion spring, torque is generated in the direction of opening the lid around the hinge portion of the lid when the lid is closed. Around the hinge part, torque is applied to the resin part that is the base of the lid in the opening direction, but the torque does not act on the glass material, so there is peeling between the glass material and the base resin part. There is a problem that it occurs or causes the hinge portion to break.

In order to solve this problem, a configuration has been proposed in which the end face of the glass material is sandwiched between different fitting parts from the lower surface to the upper surface (Patent Document 1).

In the configuration of Patent Document 1, by mechanically fixing the glass material, it is possible to prevent the glass material from peeling off and improve the strength.

JP-A-2017-221326

However, in the configuration of Patent Document 1, since the unevenness of parts other than the glass material appears around the lid, it is not possible to express a flat design on the entire surface. Further, when the user cares for the lid, the steps and uneven gaps around the lid may be harmful, and dust and dirt may collect in the steps and uneven gaps around the lid.

The present disclosure provides a washing machine capable of suppressing peeling of a glass material and breakage of a hinge structure while maintaining a design in which the surface of a lid is flat.

The washing machine in the present disclosure includes a housing, an opening for entering and exiting laundry provided in the upper part of the housing, and a lid for opening and closing the opening, and the lid has a surface portion. A constituent design surface member, a lid resin member that supports the back surface side of the design surface member, an adhesive member that adheres the design surface member and the lid resin member, and a lid back resin that covers the back surface of the lid resin member. It has a member and a hinge portion structure that rotatably supports the lid body, and the hinge portion structure is attached to a main support plate that supports the lid body and the main support body. It has a shaft that serves as the center of rotation of the lid, and an elastic body that is attached to the main support and urges the lid in the opening direction, and is connected to the main support plate to the left and right of the lid. A pair of support plates for supporting the side portions are provided.

The washing machine in the present disclosure can suppress peeling of the glass material and breakage of the hinge structure while maintaining a design in which the surface of the lid is flat.

The main support plate 541 is joined to the lid resin member 530 with screws. The main support plate 541 is provided with a stepped shape 544 on the left and right. The lid resin member 530 has an opening 531 formed at a position corresponding to the stepped shape 544, and the stepped shape 544 is directly adhered to the design surface material 510 by the adhesive member 520 via the opening 531. .. Since the main support plate 541 uses sheet metal, the lid resin member 530 and the design surface material 510 are adhered to each other by adhering the design surface material 510 to the sheet metal which is higher in adhesion than the resin. Demonstrates strong adhesive strength. When concentrated stress is generated in the hinge portion, the design face material 510 and the main support plate 541 are firmly adhered to each other, which has an effect of preventing the design face material from peeling off.

A left spring 545 and a right spring 546 are arranged on the main support plate 541. In the present embodiment, the left spring 545 and the right spring 546 use torsion springs, but other springs may be used. The left spring 545 and the right spring 546 are provided with a spring support member 547 and a shaft 548, respectively. When opening the heavy lid body 500, a higher opening torque is generated by the left spring 545 and the right spring 546 in order to reduce the load on the user. By preventing the spring support member 547 and the shaft 548 from deforming the left spring 545 and the right spring 546 with respect to the center of the rotating shaft, the twist of the spring is regulated and the loss of the opening torque is reduced.

The main support plate 541 includes a right support plate 542 and a left support plate 543. The right support plate 542 and the left support plate 543 are formed of a metal material, extend in a direction away from the main support plate 541, and are bent in the extending direction to form a U-shaped cross section.

The right support plate 542 and the left support plate 543 are joined to the lid resin member 530 and the main support plate 541 with screws. The joining of each of these parts may be a joining by welding or an integral part configuration.

Since the left support plate 543 and the right support plate 542 are made of separate parts from the main support plate 541, they can be formed in a different material and thickness from the main support plate 541, and are appropriately selected depending on the applied stress. Can be done.

Bending stress is generated on the end face of the hinge portion of the lid 500 due to the opening torque generated from the left spring 545 and the right spring 546, and the design face material 510 and the lid resin member 530 are peeled off via the adhesive member 520. Stress is generated, and there is a risk that the design face material 510 may be peeled off, deformed, or broken.

Generally, as a preventive measure against such a problem, as described in the column of the prior art, another part is fitted to the end face of the hinge portion of the lid to increase the strength and prevent peeling.

However, in this configuration, the entire upper surface of the lid cannot be flattened, which hinders the sense of quality. Further, since the design surface material 510 has an uneven fitting portion, dust and dirt are clogged on the appearance surface, which causes a problem from the viewpoint of maintainability.

By providing the right support plate 542 and the left support plate 543, the area that receives the opening torque by the hinge portion can be increased, and the bending stress generated on the end face of the hinge portion of the lid 500 due to the opening torque is relaxed. can do. The maximum deformation portion of the lid resin member 530 due to the action of the opening torque can be dispersed from the end face of the hinge portion to the lid body 500 and the central portion. This prevents the design face material 510 from peeling, deforming, or breaking. Therefore, unlike a general washing machine lid, the design surface material 510 can be formed on the entire surface of the lid body 500 to express a flat feeling and a high-class feeling.

In addition, since the design surface material 510 is used on the entire surface and there is no fitting configuration with other parts, dust and dust accumulation are suppressed, and maintainability is improved for easy maintenance.

The lid resin member 530, the main support plate 541, the right support plate 542, and the left support plate 543 are covered with the lid back resin material 570 to form the lid body 500.

By covering the hinge structure 540 with the lid back resin material 570, a complicated configuration can be hidden, the back surface of the lid 500 can be made smooth, and the back surface of the lid 500 can be easily maintained. can do.

A recess is provided in the front end portion of the lid back resin material 570 to form a handle portion for opening and closing the lid body 500 of the user.

FIG. 7 is a schematic perspective view of the washing machine in a state where the lid is separated from the housing.

The lid body 500 is configured as described above and is inserted into the top wall 250. A top wall support member 600 is arranged inside the top wall 250. The top wall support member 600 is mainly composed of sheet metal parts. The top wall support member 600 is provided with a spring receiving portion (not shown).

The left spring 545 and the right spring 546 are erected on the spring receiving portion and the main support plate 541 to urge the lid body 500 in the opening direction.
