As shown in FIG. 5, a pivot shaft 11 extending in the left-right direction is provided at the base end of the lid 3 that opens and closes the opening 10, and is covered with a hinge cover 31. The rotating shaft portion 11 is held by inserting and fitting the lower portion 32a of the damper holder 32 into the holder holding portion 34 (see FIG. 4) provided on the top cover 5 of the washing machine main body 2 and thereby the lid. 3 is fixed to the washing machine body 2. The holder holding portion 34 is made of, for example, a metal reinforcing plate, and as shown in FIG. 4, it serves as a receiving hole for the reinforcing plate provided in the top cover 5 of the washing machine body 2.

The hinge cover 31 is provided with a slit 31a, and a first spring end portion 36a of a spring 36 provided inside the rotating shaft portion 11 projects from the slit 31a. The spring 36 applies a biasing force to the opening side of the lid 3. The spring 36 and the first spring end portion 36a will be described later. Further, the rotating shaft portion 11 is provided with a gap portion 31b through which the shaft 38 provided inside is exposed. In the gap portion 31b, the shaft 38 is held by a shaft holding portion (not shown) provided on the top cover 5, so that the lid 3 is rotatably held.

As shown in FIG. 6, the rotating shaft portion 11 includes a reinforcing member 42. The reinforcing member 42 includes a damper holder 32, a damper cover 40 for holding an internal damper (not shown), a spring 36, and a shaft 38. ing. As shown in FIG. 10, the reinforcing member 42 is a metal plate member having a substantially S-shaped cross section and having the left-right direction as the longitudinal direction, and includes a front surface portion 42a, a bottom surface portion 42b, and a rear surface portion 42g. have. The portion having the above-mentioned substantially S-shape is a portion where an upper folded portion 42e described later is provided. The reinforcing member 42 has a screw hole 40b and is attached to the lid 3 by a screw (not shown). The reinforcing member 42 is provided with a pair of shaft fixing portions 38a and 38b that protrude forward and are provided with through holes 38c on the left and right of the back surface portion 42g, and the shaft 38 is provided in the through holes 38c of the shaft fixing portions 38a and 38b. It is installed through.

Further, the reinforcing member 42 is an upper portion that is a folded portion formed by bending the first restricting portion 43 for locking the first spring end portion 36a of the spring 36 rearward at a substantially right angle in the upper portion of the front surface portion 42a. The folded-back portion 42e and the lower folded-back portion 42f, which is formed by bending the lower portion of the front surface portion 42a at a substantially right angle to the rear, are provided. Further, the reinforcing member 42 includes a second restricting portion 44 for locking the second spring end portion 36b of the spring 36 on the bottom surface portion 42b.

The spring 36 is a torsion coil spring, and includes a coil portion 36c formed by winding a metal wire, and linear first spring end portions 36a and second spring end portions 36b at both ends thereof. The first spring end portion 36a and the second spring end portion 36b have an angle of approximately 180 degrees in a state where no torsion force is applied to the spring. The coil portion 36c is composed of a metal wire wound directly around the coil axis, and a cavity is formed along the coil axis. As shown in FIG. 7, in the spring 36, the shaft 38 penetrates the cavity of the coil shaft of the coil portion 36c, the first spring end portion 36a is locked to the first restricting portion 43, and the second spring end portion. 36b is locked and held by the second restricting portion 44.

The damper holder 32 inscribes and holds about half of a damper (not shown) held in the damper cover 40. The damper holder 32 is integrally attached to the lid 3 by a damper cover 40 that fixes the damper to the lid 3. The damper cover 40 is screwed to the reinforcing member 42 with a screw 40a. The damper holder 32 and the damper held inside the damper holder 32 constitute a damper mechanism. The damper holder 32 is configured to be rotatable with a damper held therein as a rotation axis in a state where a resistance force of the damper is applied. That is, the damper mechanism slows down the movement of the lid 3 by imparting a resistance force to the opening/closing operation of the lid 3 so that the lid 3 operates slowly.

The first spring end portion 36a of the spring 36 is locked to the first restriction portion 43, as shown in FIGS. 7 to 9. As shown in FIGS. 10 and 11(a), the first restricting portion 43 includes a rear restricting portion 43a, a left restricting portion 43b, a right restricting portion 43c, and a front restricting portion 43d. It should be noted that FIG. 11A is a top view of the first restricting portion 43 viewed from the D direction shown in FIGS. 7 to 10. An upper folded portion 42e is formed at the upper end of the front surface portion 42a so as to be bent rearward so as to form a substantially right angle. The upper folded portion 42e is provided with a U-shaped cutout portion 42c. The three inner sides of the portion 42c are configured to be a rear regulation portion 43a, a left regulation portion 43b, and a right regulation portion 43c. The rear restricting portion 43a, the left restricting portion 43b, and the right restricting portion 43c are provided at the upper end of the reinforcing member 42, and are located on the same plane as the upper folded portion 42e. The front portion of the left restricting portion 43b of the U-shaped notch portion 42c is open to the outside so that the first spring end portion 36a can be taken in and out.

The rear regulating portion 43a abuts the first spring end portion 36a, which is biased in the rearward direction, from the rearward direction to the frontward direction, and regulates the rearward movement of the first spring end portion 36a. The left restricting portion 43b has a protrusion shape and protrudes forward, and a side surface is formed on the right side thereof, and the side surface shape constitutes a catching portion. The left restricting portion 43b is in contact with the first spring end portion 36a by this side surface and restricts the leftward movement thereof. The right restricting portion 43c constitutes a side surface located on the right side of the rear restricting portion 43a, contacts the first spring end portion 36a, and restricts the rightward movement thereof. In addition, in the embodiment, the example in which the right restricting portion 43c is provided in the cutout portion 42c of the upper folded portion 42e is shown, but the invention is not limited to this. For example, the right regulation portion 43c may be provided in the hole portion 42d of the lower folded portion 42f, that is, at a position adjacent to the front regulation portion 43d.

A hole 42d is formed in a lower folded portion 42f provided on the reinforcing member 42 located below the rear regulating portion 43a. The front end of the hole 42d constitutes a front regulation portion 43d. The front regulating portion 43d abuts the first spring end portion 36a from the front side and regulates the forward movement of the first spring end portion 36a indicated by the arrow E in FIG. Positioning of the first spring end portion 36a in the front-rear direction is performed by the above-described rear regulation portion 43a and this front regulation portion 43d. At the time of assembly, the first spring end 36a is passed through the hole 42d and the notch 42c and is locked to the first restriction portion 43.

The hole 42d and the notch 42c are formed large. The larger the hole portion 42d and the cutout portion 42c, the greater the degree of freedom of the spring 36 and the easier handling. Therefore, when the washing machine 1 is assembled, the spring 36 can be easily attached.

Further, the front regulation portion 43d regulates the movement of the first spring end portion 36a indicated by the arrow E in FIG. 10 in the front direction. As a result, the biasing force of the spring 36 suppresses the biasing force that pushes the spring 36 forward. Therefore, the inside of the hollow portion of the coil portion 36c of the spring 36 is prevented from coming into contact with the shaft 38. By suppressing the contact of the spring 36 with the shaft 38, friction is eliminated, so that the opening/closing torque when the lid 3 is opened/closed can be reduced, and thus the lid 3 can be opened/closed smoothly.

Further, the position where the first spring end portion 36a comes into contact with the rear regulating portion 43a is different from the position where it comes into contact with the front regulating portion 43d. That is, as shown in FIG. 10, the length L1 from the coil portion 36c of the spring 36 to the position where the first spring end portion 36a contacts the rear regulating portion 43a is equal to the length L1 from the coil portion 36c of the spring 36 to the front regulating portion 43d. Is longer than the length L2 up to the position where it abuts against, that is, the rear regulating portion 43a is located farther from the coil portion 36c than the front regulating portion 43d. In this way, the first spring end portion 36a is provided between the rear restricting portion 43a that restricts the backward movement of the first spring end portion 36a and the coil portion 36c of the spring 36 that generates the biasing force of the spring 36. Since the front restricting portion 43d that restricts the forward movement of the spring is positioned, the lever 36 can effectively prevent the spring 36 from pushing the spring 36 forward due to its urging force. This can prevent the inside of the hollow portion of the coil shaft of the spring 36 from coming into contact with the shaft 38, so that the occurrence of friction due to the contact can be avoided and the opening/closing torque when the lid 3 is opened/closed can be reduced. Since it is reduced, the lid 3 can be opened and closed smoothly.

The second spring end portion 36b is locked to the second restriction portion 44. The second restricting portion 44 to which the second spring end portion 36b is locked is a slit opened in the front direction. When the washing machine 1 is assembled, the second spring end portion 36b is attached and detached through the slit, so that the spring 36 can be easily attached.

As shown in FIG. 11B, the second restriction portion 44 is a slit portion 44d provided on the bottom surface portion 42b, and the slit portion 44d includes a rear restriction portion 44a, a left restriction portion 44b, and a right restriction portion 44c. Equipped with. Note that FIG. 11B is a bottom view of the second restricting portion 44 as viewed from the F direction shown in FIGS. 7 to 10.

The rear regulating portion 44a regulates the backward movement of the second spring end portion 36b, the left regulating portion 44b regulates the leftward movement, and the right regulating portion 44c regulates the rightward movement. When the spring 36 is attached, the second spring end portion 36b is biased in the rear direction and is in close contact with the rear regulation portion 44a, and is positioned by the rear regulation portion 44a, the left regulation portion 44b, and the right regulation portion 44c. ..

The slit portion 44d is opened in the front direction, and when the lid 3 is closed with the second spring end portion 36b locked in a locking hole (not shown) provided in the top cover 5, The spring end portion 36b rotates in the front direction of the slit portion 44d.

12 to 14 are views showing modified examples of the washing machine 1 according to the embodiment. 12 is a view corresponding to FIG. 8, FIG. 13 is a view corresponding to FIG. 10, and FIG. 14 is a view corresponding to FIG. The difference between the modified examples is that the notch 42c in FIG. 8 is replaced with a hole 46 that is a hole provided in the upper folded portion 42e, as shown in FIGS. 12 to 14. The first spring end 36 a is locked in the hole 46 by passing through the hole 46. When the first spring end portion 36a is attached, the first spring end portion 36a is biased toward the rear wall of the hole 46 by the biasing force of the spring 36 in the rear direction. Other configurations are the same as those of the embodiment described in FIGS. 1 to 11.

With this configuration, the movement of the first spring end portion 36a in the front-rear and left-right directions is omnidirectionally restricted, so that the first spring end portion 36a is prevented from falling out of the hole portion 46 when the lid 3 is opened and closed. As a result, the first spring end portion 36a is positioned in the front-rear direction and the left-right direction, so that when the shaft 38 is attached, the spring 36 can be prevented from moving in the front-rear direction and the left-right direction, and the work of attaching the shaft 38 becomes easy.

The washing machine 1 according to the embodiment has the following effects.
In the washing machine 1 according to the embodiment, the first spring end portion 36a of the spring 36 is in contact with and locked by the rear regulation portion 43a and the front regulation portion 43d. Thereby, the first spring end portion 36a is restricted from moving in the rearward direction by the rear restricting portion 43a, and is restricted from moving in the forward direction by the front restricting portion 43d. Therefore, the movement of the spring 36 pushed forward by the biasing force of the spring 36 in the opening direction is suppressed, and thus the inside of the cavity of the coil shaft of the coil portion 36c of the spring 36 is prevented from coming into contact with the shaft 38. .. Therefore, the contact of the spring 36 with the shaft 38 is suppressed, so that the opening/closing torque when the lid 3 is opened/closed can be reduced, and thus the lid 3 can be opened/closed smoothly.

In the washing machine 1 according to the embodiment, the left restricting portion 43b restricts the leftward movement of the first spring end 36a. This prevents the first spring end portion 36a from coming off to the left. The right restricting portion 43c restricts the rightward movement of the first spring end portion 36a, which prevents the first spring end portion 36a from coming off in the rightward direction. Further, as a result, the first spring end portion 36a is positioned in the left-right direction, so that the first spring end portion 36a is prevented from falling off in the left-right direction. Furthermore, since the spring 36 can be restrained from moving to the left and right when the shaft 38 is attached, the work of attaching the shaft 38 becomes easy.

In addition, in the washing machine 1 according to the embodiment, the front portion of the left restricting portion 43b is opened outward, and the large notch portion 42c is provided. Further, a hole 42d is formed in the lower folded portion 42f provided on the reinforcing member 42, and the front end of the hole 42d constitutes a front regulating portion 43d. Accordingly, when the first spring end portion 36a is routed during the assembly of the washing machine 1, the left restricting portion 43b is formed in the open portion, the large cutout portion 42c, and the lower folding portion 42f. The formed hole 42d can be used. Therefore, the space around the first spring end portion 36a can be set large, and the coil portion 36c can be easily arranged at a position suitable for inserting the shaft 38, so that the spring 36 can be easily attached.

Further, in the washing machine 1 according to the embodiment, the first spring end portion 36a abuts the rear regulation portion 43a and the front regulation portion 43d, whereby movement of the first spring end portion 36a in the front direction and the rear direction is regulated. .. If the front regulating portion 43d does not exist and the first spring end portion 36a is attached to the reinforcing member 42, the worker presses the spring 36 backward while countering the strong biasing force of the spring 36. The first spring end portion 36a is brought into contact with the first restricting portion 43 while at the same time inserting the shaft 38 into the spring 36 to fix the shaft 38 to the shaft fixing portions 38a and 38b. Become. In the washing machine 1 according to the present embodiment, since the rear regulating portion 43a and the front regulating portion 43d are present, if the first spring end portion 36a is brought into contact with these, the movement of the spring 36 in the front-rear direction is regulated. can do. Therefore, when assembling the washing machine 1, it is possible to avoid difficult work such as inserting the shaft 38 into the spring 36 while opposing the strong urging force of the spring 36, so that the spring 36 can be easily attached to the reinforcing member 42. .. Further, when the washing machine 1 is assembled, the position of the coil portion 36c can be easily held at an appropriate position, so that the work of passing the shaft 38 through the coil portion 36c is simplified, and thus the ease of assembly is improved.

Further, since the spring 36 applies a biasing force to the opening direction side of the lid 3, the opening operation of the lid 3 becomes easy. At this time, the damper holder 32 and a damper mechanism (not shown) provide a resistance force to the opening operation by the urging force of the spring 36, so that the opening operation of the lid 3 becomes slow and vigorous. Since the lid 3 is prevented from rotating, the lid 3 can be smoothly opened. Further, when the lid 3 is closed, the damper mechanism applies a resistance force to the operation of closing the lid 3 vigorously by the weight of the lid 3, so that the lid 3 is closed slowly. It is possible to smoothly perform the closing operation of the lid 3. In particular, when the lid 3 is made of the glass surface material 17 having a large mass as in the embodiment, the action of assisting the opening operation by applying the urging force of the spring 36 to the opening side of the lid 3 and the closing operation. Since the closing operation is slowed by the resistance force applied by the damper mechanism during operation, a smooth operation of the lid 3 can be realized, which matches the taste of the user.

According to the washing machine 1 of the embodiment, the rotating shaft portion 11 (support member) includes the shaft 38 that serves as the rotating shaft of the lid 3, the spring 36 that applies a biasing force to the opening side of the lid 3, and the shaft 38. , And a reinforcing member 42 to which the spring 36 is attached. The spring 36 includes a coil portion 36c, a linear first spring end portion 36a (first end portion), and a second spring end portion 36b ( Second end portion), and the reinforcing member 42 includes at least a rear regulating portion 43a that regulates a backward movement of the first spring end portion 36a and a front regulating portion 43d that regulates a forward movement of the first spring end portion 36a. And are equipped with. With this configuration, since the movement of the spring 36 pushed in the forward direction is suppressed, the contact of the coil portion 36c of the spring 36 with the shaft 38 is suppressed, and the opening/closing torque when the lid 3 is opened/closed can be reduced.

According to the washing machine 1 of the embodiment, the reinforcing member 42 includes the left regulating portion 43b that regulates the leftward movement of the first spring end portion 36a and the right regulating portion 43c that regulates the rightward movement of the first spring end portion 36a. .. As a result, the first spring end portion 36a is positioned in the left-right direction, so that the first spring end portion 36a is prevented from falling off in the left-right direction, and the spring 36 moves left and right when the shaft 38 is attached. Since this can be suppressed, the work of attaching the shaft 38 becomes easy.

According to the washing machine 1 in the embodiment, the position where the first spring end portion 36a contacts the rear regulation portion 43a and the position where the first spring end portion 36a contacts the front regulation portion 43d are different. As a result, there is a difference in distance between the position where the first spring end portion 36a abuts on the rear regulating portion 43a and the position where the first spring end portion 36a abuts on the front regulating portion 43d. It is possible to effectively suppress the movement of the spring 36 that pushes the spring 36 forward due to the biasing force thereof.

According to the washing machine 1 in the embodiment, the left regulation part 43b or the right regulation part 43c is a regulation part of either the front regulation part 43d or the rear regulation part 43a, which is far from the coil part 36c. At least one of the restriction portions can be provided.

If the left regulating portion 43b and the right regulating portion 43c are arranged in the lower folded portion 42f, that is, the hole portion 42d, which is the regulating portion on the closer side, the front side, the right side, and the left side movement on the side closer to the coil portion 36c are moved. Since it is restricted, it becomes difficult to insert the first spring end portion 36a. On the other hand, when one of the left restricting portion 43b and the right restricting portion 43c is arranged in the upper folded portion 42e which is the restricting portion on the far side, the restriction by the hole portion 42d which is the restricting portion on the near side is restricted by the left restricting portion. Only one of 43b or the right regulating portion 43c is provided. Therefore, the hole portion 42d can be formed larger in the left-right direction by that amount, and the work of attaching the spring 36 becomes easy. Further, when the left restricting portion 43b and the right restricting portion 43c are arranged on the distant restricting portion, it is not necessary to provide the left restricting portion 43b and the right restricting portion 43c in the hole portion 42d that is the closer restricting portion. .. Therefore, the hole 42d can be formed larger in the left-right direction, and the work of attaching the spring 36 can be further facilitated.

According to the washing machine 1 in the embodiment, either the front regulation portion 43d or the rear regulation portion 43a far from the coil portion 36c is formed on the upper folded portion 42e of the reinforcing member 42. As a result, the first restricting portion 43 including the rear restricting portion 43a and the front restricting portion 43d can be provided on the same reinforcing member 42, so that the reinforcing member 42 can be easily processed and its strength can be improved. At times, the positioning of the first spring end portion 36a becomes easy.
