Detailed Description
(example 1)
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 1 according to embodiment 1.
The washing machine 1 is a vertical washing machine including a washing machine main body 10 and an upper cover 20. The washing machine main body 10 has a laundry inlet 101 (see fig. 2), and the upper cover 20 is hinged to the washing machine main body 10 to openably and closably cover the laundry inlet 101. Specifically, the upper cover 20 is hinge-coupled to the upper panel 11 constituting the upper portion of the washing machine main body 10.
In the washing machine 1, the upper cover 20 is a heavy component. In the example of fig. 1, the top surface of the upper cover 20 is formed as a glass plate, and the upper cover 20 is provided with an operation panel 21 (e.g., a touch panel). Further, an operation circuit may be built in the inside of the upper cover 20. That is, the upper cover 20 of fig. 1 is heavy due to the provision of the glass plate, the operation circuit, and the like.
Next, a specific structure of the hinge joint portion between the upper panel 11 and the upper cover 20 will be described. Fig. 2 is a perspective view of the upper panel 11 with the upper cover 20 removed, viewed from obliquely above. Fig. 3 is a perspective view of the upper cover 20 viewed obliquely from below. In fig. 2 and 3, the hinge shaft 30 is shown in fig. 3 (on the upper cover 20 side). In fig. 2 and 3, the upper panel 11 and the upper cover 20 are shown as being separated from each other to facilitate understanding of the structure of the hinge joint, but the order of assembling the upper panel 11 and the upper cover 20 is not considered.
As shown in fig. 2, on the upper surface of the upper panel 11, at the rear of the washing machine main body 10, main body side hinge bearings 31 are provided to protrude from two positions at both ends. Further, a damper receiver 41 for holding a shaft 40 (see fig. 5) of a damper (disposed in the upper cover 20) is disposed between the main body side hinge bearings 31. The upper panel 11 and the upper cover 20 are coupled via two hinge shafts 30 divided into left and right, and the main body hinge bearings 31 serve as bearings for supporting outer ends of the respective hinge shafts 30. The damper acts as a resistance when the upper lid 20 is opened and closed, and prevents the upper lid 20 from being opened or closed violently.
As shown in fig. 3, grooves 22 are provided at two positions at both ends of the inner surface of the upper cover 20, and one ends (outer ends) of the hinge shaft 30 are respectively disposed inside the grooves 22. That is, in a state where the upper panel 11 and the upper cover 20 are coupled, the main body side hinge bearing 31 is inserted into the groove portion 22, and one end of the hinge shaft 30 is supported by the main body side hinge bearing 31.
Fig. 4 is a perspective view showing an internal configuration of the periphery of the hinge joint portion in which the outer case member is removed from the upper panel 11. As shown in fig. 4, a hinge base (bearing member) 50 forming a bearing portion 52 is provided at two positions at both ends in the longitudinal direction in the upper panel 11. The hinge base 50 has a base 51 having a longitudinal direction of the axis of the hinge shaft 30, and has bearing portions 52 at both ends of the base 51. Further, the main body side hinge bearing 31 is configured to: a bearing housing is formed as an outer housing part of the upper panel 11, and a bearing portion 52 of the hinge base 50 is inserted into the bearing housing. The hinge base 50 is fixed to a frame member inside the upper panel 11 by screw fasteners. At least the base 51 of the hinge base 50 is fastened to the frame part.
Fig. 5 is a perspective view showing an internal configuration around the hinge joint portion with the inner panel member of the upper cover 20 removed. As shown in fig. 5, two hinge shafts 30 arranged coaxially are pivotally supported inside the upper cover 20. In addition, each hinge shaft 30 is provided with a hinge spring 32 around the shaft to assist in opening the upper cover 20. The hinge spring 32 is a torsion spring that biases the upper cover 20 toward the upper panel 11 in the opening direction. As shown in fig. 3, one end of each hinge spring 32 protrudes from the inner surface of the upper cover 20 and is fixed to the upper panel 11. The other end of each hinge spring 32 is fixed to the upper cover 20.
In a state where the upper cover 20 is hinge-coupled to the upper panel 11, a load due to the hinge spring 32 is generated in the hinge base 50. Specifically, a torsional load in the longitudinal direction is generated between the base portion 51 fixed to the frame member and the bearing portion 52. In the washing machine 1 according to embodiment 1, the upper cover 20 is a relatively heavy member, and the spring force of the hinge spring 32 is also set to be a large spring force, so that the torsional load generated in the hinge base 50 is also increased accordingly. The washing machine 1 according to embodiment 1 is characterized in that the hinge base 50 is formed in a highly rigid shape so that the hinge spring 32 having a large spring force can be used without any problem.
Fig. 6 is a perspective view showing the hinge base 50. The hinge base 50 is a member manufactured by sheet metal working, and is manufactured by performing steps of cutting, punching, and bending a metal plate (sheet metal). That is, the hinge base 50 is manufactured by performing a cutting and punching process on a metal plate to form a predetermined shape, and then performing a bending process.
As shown in fig. 6, the hinge base 50 includes a base portion 51, a bearing portion 52, and a leg portion 53. The base 51 has a longitudinal axis of the hinge shaft 30, and has a plurality of screw holes 511, spring insertion holes (spring mounting portions) 512, and damper mounting holes 513 for fastening the hinge base 50. As described above, the hinge spring 32 disposed around the hinge shaft 30 is fixed to the upper panel 11 by having one end thereof protruded from the inner surface of the upper cover 20. That is, one end of the hinge spring 32 fixed to the upper panel 11 side is inserted into the through hole 102 (see fig. 2) formed in the outer case member of the upper panel 11, and is also inserted into and fixed to the spring insertion hole 512 of the hinge base 50. Since the damper receiver 41 is attached to the frame member in the same manner as the hinge base 50, the damper attachment hole 513 is formed in the hinge base 50 at a position where the damper receiver 41 is attached. Further, the base portion 51 may be provided with a reinforcing rib 514, and the reinforcing rib 514 may be formed by bending a side along the longitudinal direction of the sheet metal.
The bearing portions 52 are formed to protrude upward so as to be orthogonal to the main surface of the base portion 51 at two positions at both ends of the base portion 51 in the longitudinal direction. More specifically, the bearing portion 52 is formed by cutting and raising the base portion 51 from the outside. The bearing portion 52 is formed with a bearing hole 521 for inserting the hinge shaft 30.
The leg portions 53 are reinforcing portions extending from both ends of the base portion 51 in the longitudinal direction, and are formed by being bent downward so as to be orthogonal to the main surface of the base portion 51. More specifically, the leg portion 53 is formed by bending downward a portion around the bearing portion 52 formed by cutting and raising. Therefore, the leg portion 53 has an opening 531 at a position corresponding to the cut and raised bearing portion 52. The front end of the leg 53 has an outwardly bent flange 532, and a screw hole 533 for fastening the leg 53 is formed in the flange 532. Further, the leg portion 53 may be provided with a reinforcing rib 534, and the reinforcing rib 534 may be formed by bending a side along the longitudinal direction of the sheet metal.
A first feature of the hinge base 50 according to embodiment 1 is that the bearing portion 52 is formed by cutting and raising from the outside of the base portion 51. By the bearing portion 52 formed by cutting and raising from the outside of the base portion 51, the bearing portion 52 is not opened after cutting and raising the bearing portion 52 in the base portion 51 which is the inside of the bearing portion 52.
A large torsional load due to the spring force of the hinge spring 32 acts on the base portion 51 inside the bearing portion 52. Thus, if an opening is formed in the base portion 51 after the bearing portion 52 is cut and raised (that is, if the bearing portion 52 is formed by cutting and raising from the inside), the rigidity at a position receiving a large torsional load is reduced by the opening, and it becomes difficult to use the hinge spring 32 having a large spring force (there is a possibility that the base portion 51 is bent). In the hinge base 50 according to embodiment 1, the rigidity of the base portion 51 is not reduced by the opening, and a structure suitable for using the hinge spring 32 having a large spring force is provided.
Further, since the inside of the bearing portion 52 is not opened in the base portion 51, the screw hole 511 for fastening the hinge base 50 can be provided as close as possible to the bearing portion 52. In the example shown in fig. 6, screw hole 511A is provided as close as possible to bearing portion 52. Since the torsional load of the hinge base 50 is generated by the torsional moment between the base portion 51 and the bearing hole 51 of the bearing portion 52, the base portion 51 is preferably fastened as close to the bearing portion 52 as possible in order to increase the rigidity corresponding to the torsional moment. The hinge base 50 according to embodiment 1 can be fastened by the screw holes 511A as close as possible to the bearing portion 52 of the base 51.
(example 2)
The hinge base 50 according to embodiment 2 is a second feature of the present invention in that a leg portion 53 is provided.
As described in embodiment 1, the bearing portion 52 of the hinge base 50 is formed by cutting and raising from the outside of the base portion 51. Therefore, there is a sheet metal portion remaining after the bearing portion 52 is cut and raised, outside the base portion 51. In the hinge base 50, the remaining sheet metal portion is bent downward to form a leg portion 53. That is, the leg portion 53 is provided at the same position as the bearing portion 52 in the longitudinal direction of the hinge base 50. The leg portion 53 is bent toward the base portion 51 opposite to the bearing portion 52.
The leg portion 53 is provided at its front end with a flange portion 532 having a screw hole 533, and the flange portion 532 is fastened to a frame member inside the upper panel 11. Thus, the leg portion 53 functions as a reinforcing portion against a torsional load applied to the base portion 51, and the rigidity of the hinge base 50 can be further improved.
In the hinge base 50 shown in fig. 6, the remaining sheet metal portion cut and raised at the bearing portion 52 is bent downward to form the leg portion 53, but the remaining sheet metal portion may be formed as a reinforcing portion extending outward on the same surface as the base portion 51 without being bent. However, the leg portion 53 is particularly preferable because the following two advantages are obtained.
(1) Since the leg portion 53 bent downward is fixed at a position distant from the main surface of the base portion 51, when a torsional moment is generated between the base portion 51 and the bearing hole 521 of the bearing portion 52, a counter moment against the torsional moment acts on the end portion of the base portion 51. This improves the function as a reinforcing portion against a torsional load applied to the base portion 51. Further, regarding this effect, it is preferable that the distance between the base portion 51 and the screw hole 533 of the flange portion 532 is longer than the distance between the base portion 51 and the bearing hole 521 of the bearing portion 52, because the load applied to the leg portion 53 is reduced.
(2) By bending the remaining sheet metal portion of the bearing portion 52 after the cutting and raising downward, the length of the hinge base 50 can be shortened as compared with the case where the sheet metal portion is extended outward without being bent. In other words, in the case where the length of the hinge base 50 is determined, the distance between the bearing parts 52 may be set longer.
In addition, the hinge base 50 shown in fig. 6 may be configured as follows: a flange 532 bent outward is provided at the tip of the leg 53, and the flange 532 is fastened. That is, the flange 532 is fastened to the upper surface of the frame member to which the leg 53 is fastened. However, the present invention is not limited to this, and the leg portion 53 may be fastened to the side surface of the frame member without providing the flange portion 532 to the leg portion 53.
(example 3)
In the hinge base 50 shown in fig. 6, the leg portion 53 is provided at the same position as the bearing portion 52 in the longitudinal direction of the hinge base 50 (see fig. 7 (a)). However, the present invention is not limited to this, and the leg portion 53 may be provided at a position different from the bearing portion 52 in the longitudinal direction of the hinge base 50. Specifically, the leg portion 53 may be provided on the outer side of the bearing portion 52 in the longitudinal direction of the hinge base 50 (see fig. 7 (b)).
Depending on the size and shape of the frame member to which the hinge base 50 is fastened, as shown in fig. 7 (b), it may be preferable to provide the leg portion 53 and the bearing portion 52 at different positions in the longitudinal direction of the hinge base 50.
As described above, the washing machine according to the present embodiment is a washing machine including a washing machine main body and an upper cover, and includes: a hinge shaft connecting the washing machine main body and the upper cover; a bearing member mounted on the washing machine main body and serving as a bearing of the hinge shaft, the bearing member having: a base fixed to a frame member inside the washing machine main body, the base having a shape in which an axial direction of the hinge shaft is a longitudinal direction; bearing portions formed to protrude upward from the base portion at two positions at both ends of the base portion in the longitudinal direction, and to which the hinge shaft is attached; and a reinforcing part extending from both ends of the base part in the longitudinal direction and fixed to a frame member inside the washing machine main body, wherein the bearing part is formed by cutting and raising from the outside in the longitudinal direction of the base part.
In addition, the washing machine may be configured as follows: the washing machine is provided with a hinge spring which is connected with the washing machine main body and the upper cover and applies force to the direction of opening the upper cover, and the base part is provided with a spring mounting part on which the hinge spring is mounted.
In addition, the washing machine may be configured as follows: the reinforcing portion is bent toward the opposite side of the bearing portion with respect to the base portion.
In addition, the washing machine may be configured as follows: the distance from the base portion to the end portion of the reinforcing portion is longer than the distance from the base portion to the end portion of the bearing portion.
In addition, the washing machine may be configured as follows: at least one of the base portion and the reinforcing portion has a reinforcing rib formed by bending.
The washing machine according to the present invention can be described as follows. The present invention provides a washing machine having a washing machine main body and an upper cover hinged to the washing machine main body, the washing machine comprising: a hinge axis; a hinge spring disposed around the hinge shaft and urging the upper cover in an opening direction; a bearing member which is attached to the washing machine main body and serves as a bearing for the hinge shaft, the bearing member being formed by bending a metal plate and including: a base fixed to a frame member inside the washing machine main body, the base having a longitudinal direction of the hinge shaft; and bearing portions formed by protruding upward at two positions at both ends of the base portion in the longitudinal direction so as to be orthogonal to the main surface of the base portion, the bearing portions being formed by cutting and raising the base portion from the outside of the base portion.
According to the above configuration, in the bearing member manufactured by sheet metal working, the bearing portion is formed by cutting and tilting the bearing portion from the outside of the base portion, and the opening is not formed in the base portion which becomes the inside of the bearing portion after cutting and tilting the bearing portion. Thus, the rigidity of the base portion on which the spring force of the hinge spring acts is not reduced by the opening, and a structure suitable for using a hinge spring having a large spring force is obtained.
In addition, the washing machine may be configured as follows: the washing machine further includes a reinforcing portion extending from both ends of the base portion in the longitudinal direction and fixed to the frame member inside the washing machine main body.
According to the above configuration, the rigidity of the hinge base can be further improved by the reinforcing portion. In addition, the remaining metal plate portion after the bearing portion is cut and raised can be effectively used.
In addition, the washing machine may be configured as follows: the reinforcing portion is bent toward the opposite side of the bearing portion with respect to the base portion.
According to the above configuration, when the reinforcing portion bent to the opposite side to the bearing portion generates a torsional moment between the base portion and the bearing hole of the bearing portion, a reaction moment to the torsional moment can be applied to the end portion of the base portion, thereby improving the function as the reinforcing portion. In addition, the reinforcement portion can prevent the bearing member from becoming long.
In addition, the washing machine may be configured as follows: the reinforcement portion is fixed to the frame member, and a distance between the screw holes of the base portion and the reinforcement portion is set to be longer than a distance between the bearing holes of the base portion and the bearing portion.
According to the above configuration, when a reaction moment acts on the end portion of the base portion, the load applied to the reinforcing portion can be reduced.
In addition, the washing machine may be configured as follows: the base portion is fixed to the frame member by a screw fastener, and the screw hole provided in the base portion includes a screw hole provided close to an inner side of the bearing portion.
According to the above configuration, since the base portion can be fixed as close to the bearing portion as possible, the rigidity against the torsional moment between the base portion and the bearing hole of the bearing portion can be improved.
In addition, the washing machine may be configured as follows: at least one of the base portion and the reinforcing portion has a reinforcing rib formed by bending a side along a longitudinal direction of the metal plate.
According to the above configuration, the rigidity of the base portion or the reinforcing portion can be improved by the reinforcing rib which is simply formed.
The embodiments disclosed herein are all examples in all aspects and are not to be construed 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. The meaning and range equivalent to the scope of the claims are intended to be encompassed by the present invention.
