Disclosure of Invention
Technical problem to be solved by the invention
In a conventional washing machine, the general configuration is as follows: hinge shaft portions are provided at two positions on both left and right sides near the rear end portion of the lid body, and stopper portions are provided near the hinge shaft portions. However, for example, when a user applies an excessive force or the like to open the lid body and an excessive load is applied to the stopper portion, if the distance between the stopper portion and the hinge shaft portion is short, a large load may be applied to the hinge shaft portion and the bearing or the like may be damaged.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a washing machine capable of reducing a load applied to a hinge shaft portion.
Means for solving the problems
In order to solve the above-described problems, the present invention provides a washing machine including a cover body hinged to a washing machine main body via a hinge shaft portion and openably and closably covering a laundry inlet provided in an upper surface of the washing machine main body, wherein the cover body includes first stoppers which come into contact with a part of the washing machine main body when the cover body is opened to the maximum, the hinge shaft portions are provided at two positions on both left and right sides near a rear end portion of the cover body, and the first stoppers are provided between the hinge shaft portions at the two positions.
According to the above configuration, by providing the first stopper portion between the two hinge shaft portions, the distance between the first stopper portion and the hinge shaft portion can be increased along the axial direction of the hinge shaft portion. Thus, even if an excessive load is applied to the first stopper portion, the force can be absorbed by deformation of the lid body or the like, and an excessive large load can be prevented from being applied to the bearing of the hinge shaft portion. As a result, the bearing of the hinge shaft portion can be prevented from being damaged.
The washing machine may be configured to include a second stopper portion that does not abut against the washing machine main body only when the cover is in the maximally opened state, and that abuts against the washing machine main body when an external force is applied in the opening direction to the cover in the maximally opened state.
According to the above configuration, when an external force is applied to the cover in the opening direction from the state in which the cover is opened to the maximum, the second stopper abuts against the washing machine main body by the external force. Thus, the external force applied to the upper cover 30 is dispersed to the first stopper and the second stopper, and the allowable load of the cover can be further increased.
In the washing machine, an adjustment protrusion may be provided on a surface of the first stopper portion that contacts the washing machine main body.
According to the above configuration, the adjustment projection can be easily fine-tuned in height by adjusting the part shape of the die when the resin member of the lid body is molded. Then, by finely adjusting the height of the adjustment projection, it becomes easy to set the gap between the second stopper and the washing machine main body to an appropriate size when the cover is in the maximally opened state.
Advantageous effects
In the washing machine according to one embodiment of the present invention, the following effects can be achieved: by increasing the distance between the first stopper portion and the hinge shaft portion in the axial direction, when an excessive load is applied to the first stopper portion, an excessive large load can be prevented from being applied to the bearing of the hinge shaft portion, and the bearing of the hinge shaft portion can be prevented from being damaged.

Detailed Description
(first embodiment)
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view of an external appearance of a washing machine 10 according to a first embodiment.
The washing machine 10 is a vertical washing machine including a washing machine main body 11 and an upper cover (lid body) 30. The washing machine main body 11 is constituted by an outer casing 12 and an upper panel 20, and an upper cover 30 is attached to the upper panel 20. That is, the washing machine body 11 has a laundry inlet 21 in the upper panel 20, and the upper cover 30 is hinge-coupled to the upper panel 20 via a hinge shaft portion described later so as to openably cover the laundry inlet 21. The top panel 20 is also provided with an operation panel 22 (see fig. 3) for inputting operations to the washing machine 10 by a user. Since the washing machine 10 according to embodiment 1 has a feature that the upper cover 30 is attached to the upper panel 20, only the upper panel 20 and the upper cover 30 will be described below.
First, the structure of the upper cover 30 will be described with reference to fig. 2. In fig. 2, (a) is a plan view showing the upper cover 30, (B) is a rear view, (c) is a sectional view a-a of (B), and (d) is a sectional view B-B of (B).
The upper cover 30 is a flat plate-like cover body having a substantially circular shape, and is configured such that a resin frame body portion 32 is attached to one glass plate 31. Accordingly, in the washing machine 10, even in a state where the upper cover 30 is closed, the inside of the washing machine main body 11 (i.e., the inside of the washing tub) can be viewed through the glass plate 31.
The housing portion 32 is formed with a lid-side bearing portion 33, a first stopper portion 34, and a second stopper portion 35 in the vicinity of the rear end portion on the back surface side of the upper lid 30.
The lid-side bearing portion 33 serves as a bearing for a shaft member 40 (see fig. 3) described later, and thereby the upper lid 30 and the upper panel 20 are hinge-coupled to each other. The cover side bearing portions 33 are provided at one position near both left and right ends of the upper cover 30 along the axial direction of the hinge shaft portion, and the cover side bearing portions 33 are provided at two positions in total.
The lid-side bearing 33 is a shaft hole formed inside the back surface of the upper lid 30. Therefore, the shaft member 40 passes through the opening 33A provided in the back surface of the upper cover 30
(see fig. 3) is inserted into the lid side bearing 33. Then, except when the shaft member 40 is removed, the opening 33A is covered with a cover member 36 that is detachable from the upper cover 30.
The first stopper 34 is a member for holding the center rear end portion of the upper cover 30 in a stationary state. The second stopper 35 is an arm-shaped stopper formed to protrude further downward from the back surface. The second stoppers 35 are stoppers provided close to the lid-side bearing 33, and are provided at one position near both left and right ends of the upper lid 30 in the axial direction of the hinge shaft, and are provided at two positions in total, similarly to the lid-side bearing 33. Although the second stopper 35 is also shown in the drawings referred to in the first embodiment, the second stopper 35 is one of the components suitable for the present invention, and is not an essential component in the present invention. Therefore, specific contents regarding the second stopper 35 will be described in a second embodiment to be described later.
Next, a mounting structure of the upper cover 30 to the upper panel 20 will be described with reference to fig. 3 to 5. Fig. 3 is an exploded perspective view showing an attachment structure of the upper panel 20 and the upper cover 30. Fig. 4 is an enlarged sectional view of a section of the hinge shaft portion included in the mounting structure of fig. 3.
The upper panel 20 has a main body side bearing 23 and a recess 24 on the rear side of the laundry inlet 21.
The main body side bearing 23 and the lid side bearing 33 of the upper lid 30 are coaxially arranged, and the same shaft member 40 is fitted into the main body side bearing 23 and the lid side bearing 33, whereby the upper lid 30 and the upper panel 20 are hinge-coupled. As shown in fig. 4, one end of the shaft member 40 is pivotally supported by the main body side bearing portion 23, and the other end of the shaft member 40 is pressed by the cover member 36. Thereby, the movement of the shaft member 40 in the axial direction is restricted. That is, in the washing machine 10 according to the first embodiment, the hinge shaft portion is constituted by the main body side bearing portion 23, the lid body side bearing portion 33, the shaft member 40, and the lid member 36. Although not specifically shown here, a brake damper for suppressing abrupt displacement of the upper cover 30 is preferably provided on the hinge shaft portion. As an example, a brake damper is provided on the shaft member 40 to brake rotational displacement between one end and the other end of the shaft member 40.
The recess 24 is formed to be recessed downward from the upper surface of the upper panel 20, so that a rotation space of a part of the upper cover 30 (specifically, a part rearward of the hinge shaft portion) is secured when the upper cover 30 is opened and closed by the recess 24.
When the upper cover 30 is attached to the upper panel 20, first, the rear end portion of the upper cover 30 is inserted into the recess 24, and the cover side bearing portion 33 and the main body side bearing portion 23 are coaxially arranged. Next, the shaft member 40 is inserted from the opening 33A and is slid outward, whereby the shaft member 40 is inserted into the cover-side bearing portion 33 and the main-body-side bearing portion 23. Finally, the lid member 36 is fitted into the opening 33A, and the lid member 36 is fixed to the upper cover 30 by screws or the like. Thus, the shaft member 40 is disposed across the cover side bearing 33 and the main body side bearing 23, and the upper cover 30 functions as a rotation shaft at the time of rotation that can be opened and closed with respect to the upper panel 20.
Fig. 5 is a side view of the upper panel 20 and the upper cover 30 in a state where the upper cover 30 is closed. As shown in fig. 5, the upper surface of the upper panel 20 has a slope that is slightly lower in the front than in the rear. On the other hand, the upper surface of the upper cover 30 may have the same inclination as the upper panel 20, but the inclination angle is set to be gentler than the upper panel 20. The upper surface of the upper cover 30 may be horizontal and not inclined.
Thus, in the state where the upper lid 30 is closed, the rear end side of the upper lid 30 is in a state where it is hardly lifted from the upper surface of the upper panel 20, and the front end side of the upper lid 30 can be in a state where it is lifted from the upper surface of the upper panel 20 to some extent. When opening the upper cover 30, the user can open the upper cover 30 by pulling the gap G between the front edge of the upper cover 30 and the upper panel 20 (the front edge of the upper cover 30 is used as a handle). This eliminates the need to provide a handle for opening the upper cover 30 on the upper surface of the upper cover 30 or to provide a recess for inserting a hand into the lower surface of the upper cover 30 in front of the upper panel 20.
In the case of the structure in which the handle is provided on the upper surface of the upper cover, the handle faces rearward as the upper cover is opened, and therefore the upper cover needs to have such a function as to be folded as the upper cover is opened and closed. However, the upper cover 30 having no handle on the upper surface does not need to have such a folding function, and the structure of the upper cover 30 can be simplified, which can also lead to cost reduction. In addition, when a recess for inserting a hand into the lower surface of the upper cover 30 is provided in front of the upper panel 20, the recess is provided outside the laundry inlet 21, and therefore it is difficult to form the laundry inlet 21 large relative to the upper panel 20. However, in the configuration of the present embodiment, it is not necessary to provide a recess in the top plate 20, and the laundry inlet 21 can be formed large, thereby improving usability.
Next, the function of the first stopper 34 according to the first embodiment will be described with reference to fig. 6. Fig. 6 is a sectional view of the upper cover 30 in a state of being opened to the maximum, and the upper cover 30 corresponds to the section a-a of fig. 2 (c).
In the cross section shown in fig. 6 (cross section along the front-rear direction of the washing machine 10), the central rear end portion of the upper cover 30 including the first stopper 34 is rotatable in the recess 24. When the upper cover 30 is in the state of being opened to the maximum, the first stopper 34 comes into contact with the front wall surface 24A in the recess 24, and the upper cover 30 is stopped at an appropriate position. In the upper cover 30 in the maximally opened state, the center of gravity of the upper cover 30 is located to some extent at a position rearward of the axial center of the shaft member 40. Thus, even if the user releases his or her hand from the upper cover 30, the upper cover 30 in the maximally opened state can be stably maintained in this state.
In the washing machine 10 according to the first embodiment, two hinge shaft portions are provided in the vicinity of both ends of the rear end portion hinge-coupled to the top panel 20 with respect to the top cover 30, and the first stopper portion 34 is provided between the two hinge shaft portions at the rear end portion of the top cover 30. For example, the first stopper portion 34 is provided at the center of the hinge shaft portions at two places. Therefore, the distance between the first stopper portion 34 and the hinge shaft portion can be increased along the axial direction of the hinge shaft portion. Thus, for example, even when a user applies excessive force or the like to the first stopper 34 when the upper cover 30 is opened and a large load is applied to the first stopper 34, the load applied to the bearings (the main body side bearing portion 23 and the cover side bearing portion 33) of the hinge shaft portion can be reduced by absorbing the force by deformation of the upper cover 30 between the first stopper 34 and the hinge shaft portion or the front wall surface 24A in the recess 24. As a result, the bearing of the hinge shaft portion can be prevented from being deformed or damaged.
The first stopper 34 provided at the central rear end portion of the upper cover 30 is also likely to have a wide contact width in the axial direction with the front wall surface 24A in the recess 24. Then, by forming the contact width of the first stopper 34 in a wide range, the load applied to the first stopper 34 is also dispersed, and the allowable load on the upper cover 30 or the front wall surface 24A can be increased.
In the upper cover 30 according to the first embodiment, the glass plate 31 is not completely circular in plan view, but is formed in a shape having a D-shaped cutout portion in a part thereof (a shape obtained by cutting a part of a circle with a chord). By providing the D-shaped notch portion in the glass plate 31, the glass plate 31 can be easily aligned in a predetermined direction when the upper cover 30 is assembled, and for example, when characters or patterns are printed on the glass plate 31, the characters or patterns can be prevented from being inclined.
The D-shaped notch of the glass plate 31 is provided on the rear end side of the upper cover 30, and the surface of the first stopper 34 that contacts the front wall surface 24A is located in the notch region of the glass plate 31 formed by the D-shaped notch when the upper cover 30 is viewed in plan. Thus, as shown in fig. 6, in a state where the first stopper 34 is in contact with the front wall surface 24A, the stress (force in a direction orthogonal to the contact surface of the first stopper 34) applied to the upper cover 30 from the front wall surface 24A via the first stopper 34 acts only on a region not overlapping with the glass plate 31, and does not act directly on the glass plate 31. Therefore, the glass plate 31 can be prevented from floating from the frame portion 32 or from being broken or the like on the glass plate 31.
(second embodiment)
In the second embodiment, the function of the second stopper 35 will be described with reference to fig. 7. Fig. 7 is a sectional view of the upper cover 30 in a state of being opened to the maximum, and the upper cover 30 corresponds to a section B-B of fig. 2 (d).
In the cross section shown in fig. 7 (cross section along the front-rear direction of the washing machine 10), the rear end portion of the upper cover 30 including the first stopper 35 is rotatable in the recess 24. However, even in a state where the upper cover 30 is opened to the maximum, the second stopper 35 does not abut against the front wall surface 24B in the recess 24 unless an external force is applied to the upper cover 30 from a user or the like. That is, in the state shown in fig. 7, the second stopper 35 is located at a small gap (suitably, about 0.5mm to 2 mm) between the recess 24 and the front wall surface 24B.
When the upper cover 30 is in the state of being opened to the maximum, the second stopper 35 is not normally stressed because there is a gap between the second stopper 35 and the front wall surface 24B. However, when the upper cover 30 is in the state of being opened to the maximum, since the gap between the second stopper 35 and the front wall surface 24B is small, if an external force is applied from this state in the opening direction of the upper cover 30, the upper cover 30 or the hinge shaft portion is deformed by the external force, and the second stopper 35 abuts against the front wall surface 24B. Since the second stopper 35 abuts against the front wall surface 24B, the external force applied to the upper cover 30 is dispersed to the first stopper 34 and the second stopper 35, and the allowable load of the upper cover 30 can be further increased. Further, since the second stopper 35 abuts against the front wall surface 24B, deformation of the upper cover 30 or the front wall surface 24A can be suppressed, and thus deformation or breakage of the upper cover 30 or the front wall surface 24A to such an extent that the original shape is not restored can be prevented.
(third embodiment)
The first stopper 34 provided in the upper cover 30 can be configured to have an adjustment protrusion 34A on a surface in contact with the front wall surface 24A in the recess 24 (see fig. 3).
In the upper cover 30, the frame portion 32 on which the first stopper portion 34 is formed is made of resin, and is generally manufactured by mold forming using a mold composed of a plurality of parts. In such mold forming, it is difficult to ensure a minute dimensional accuracy as a whole. That is, in the case where the second stopper 35 of the second embodiment is provided in the upper cover 30, when the upper cover 30 is in the state of being opened to the maximum, a method is required for setting the gap between the second stopper 35 and the front wall surface 24B to an appropriate size. In addition, the posture of the upper cover 30 in the maximum opened state needs to be set appropriately. The adjustment projection 34A is provided for these methods.
The adjustment projection 34A allows the height to be easily adjusted finely by adjusting the shape of the part of the mold when the frame body 32 is molded. Then, by finely adjusting the height of the adjustment projection 34A, it becomes easy to set the gap between the second stopper 35 and the front wall surface 24B to an appropriate size when the upper cover 30 is in the maximally opened state. Further, by finely adjusting the height of the adjustment projection 34A, even if there is variation in the attachment dimension between the upper cover 30 and the upper panel 20, the posture in which the upper cover 30 is opened to the maximum can be appropriately set.
The embodiments disclosed herein are all examples and are not intended to be interpreted as limiting. Therefore, the technical scope of the present invention is defined not by the embodiments described above but by the description of the scope of the claims. Further, the scope of the present invention includes all modifications within the meaning and range equivalent to the claims.
