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 the external appearance of a washing machine 1 according to embodiment 1.
The washing machine 1 is a vertical washing machine provided with a washing machine main body 10 and an upper cover 20. The washing machine body 10 has a laundry inlet 101 (see fig. 2), and the upper cover 20 is hinge-coupled to the washing machine body 10 to cover the laundry inlet 101 so as to be openable and closable. Specifically, the upper cover 20 is hinge-coupled to the upper panel 11 constituting the upper portion of the washing machine body 10.
In the washing machine 1, the upper cover 20 is a heavy member. In the example of fig. 1, the top surface of the upper cover 20 is formed as a glass plate, and an operation panel 21 (for example, a touch panel) is provided on the upper cover 20. In addition, an operation circuit may be incorporated in the upper cover 20. That is, the upper cover 20 of fig. 1 is heavy due to 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 from obliquely upward. 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 illustrated in fig. 3 (upper cover 20 side). In fig. 2 and 3, the upper panel 11 and the upper cover 20 are described as being separated from each other for easy 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 body 10, body-side hinge bearings 31 are provided to protrude from two positions at both ends. Further, a damper receiving member 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 side hinge bearings 31 serve as bearings for supporting outer end portions of the one hinge shaft 30, respectively. The damper acts as a resistance force when the upper cover 20 is opened or closed, and can prevent the upper cover 20 from being opened or closed severely.
As shown in fig. 3, the inner surface of the upper cover 20 is provided with groove portions 22 at two positions at both ends, and one ends (outer end portions) of the hinge shafts 30 are respectively disposed inside the groove portions 22. That is, in a state where the upper panel 11 and the upper cover 20 are connected, the main body side hinge bearing 31 is inserted into the inside of the slot 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 hinge joint periphery of the outer case member removed from the upper panel 11. As shown in fig. 4, hinge bases (bearing members) 50 forming bearing portions 52 are provided inside the upper panel 11 at two positions at both ends in the longitudinal direction. The hinge base 50 has a base portion 51 having the axis direction of the hinge shaft 30 as the longitudinal direction, and bearing portions 52 are provided at both ends of the base portion 51. The main body side hinge bearing 31 is configured to: the outer housing member of the upper panel 11 forms a bearing housing, and the bearing portion 52 of the hinge base 50 is inserted into the bearing housing. The hinge base 50 is fixed to the 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 member.
Fig. 5 is a perspective view showing an internal configuration of the periphery of 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 inside the upper cover 20 are pivotally supported. 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 urges 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 side. The other end of each hinge spring 32 is fixed to the upper cover 20 side.
In a state where the upper cover 20 is hinge-coupled to the upper panel 11, a load caused by 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 and the bearing portion 52 fixed to the frame member. 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. The washing machine 1 according to embodiment 1 is characterized in that the hinge base 50 is formed in a shape having high rigidity 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 each step 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, processing the metal plate into a predetermined shape, and then further performing a bending process.
As shown in fig. 6, the hinge base 50 includes a base 51, a bearing 52, and a leg 53. The base 51 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, with the axis direction of the hinge shaft 30 being the longitudinal direction. As described above, the hinge spring 32 disposed around the hinge shaft 30 has one end protruding from the inner surface of the upper cover 20 to be fixed to the upper panel 11 side. 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 the spring insertion hole 512 of the hinge base 50 and fixed thereto. Since the damper receiving member 41 is a member attached to the frame member in the same manner as the hinge base 50, a damper attaching hole 513 is formed in the hinge base 50 at a position where the damper receiving member 41 is attached. The base 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 at two positions on both ends of the base portion 51 in the longitudinal direction so as to be orthogonal to the main surface of the base portion 51. More specifically, the bearing portion 52 is formed by cutting and tilting 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 53 is a reinforcing portion extending from both ends in the longitudinal direction of the base 51, and is formed by bending downward so as to be orthogonal to the main surface of the base 51. More specifically, the leg portion 53 is formed by bending down the peripheral portion of the bearing portion 52 formed by tilting the slit. Accordingly, the leg portion 53 has an opening 531 at a position corresponding to the cut-and-raised bearing portion 52. The distal end of the leg portion 53 has an outwardly bent flange portion 532, and a screw hole 533 for fastening the leg portion 53 is formed in the flange portion 532. 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 tilting from the outside of the base 51. The bearing portion 52 formed by tilting from the outside of the base portion 51 is cut, so that the opening is not formed in the base portion 51 which is the inside of the bearing portion 52 after the bearing portion 52 is cut and tilted.
The torsional load generated by the spring force of the hinge spring 32 acts largely on the base 51 inside the bearing portion 52. Accordingly, if the opening is formed in the base portion 51 after the bearing portion 52 is cut and tilted (that is, if the bearing portion 52 is formed by cutting and tilting from the inside), the rigidity at the position receiving a large torsional load is lowered by the opening, and it becomes difficult to use the hinge spring 32 having a large spring force (there is a concern that the base portion 51 may be bent). In the hinge base 50 according to embodiment 1, the rigidity of the base 51 is not reduced by the opening, and the hinge base is suitable for a structure using the hinge spring 32 having a large spring force.
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 to the bearing portion 52 as possible. In the example shown in fig. 6, the screw hole 511A is a screw hole provided as close to the bearing portion 52 as possible. Since the torsional load of the hinge base 50 is generated by the torsional moment between the base 51 and the bearing hole 51 of the bearing portion 52, the base 51 is preferably fastened as close to the bearing portion 52 as possible in order to improve the rigidity corresponding to the torsional moment. The hinge base 50 according to embodiment 1 can be fastened by bringing the base 51 as close to the bearing 52 as possible through the screw hole 511A.
Example 2
The hinge base 50 according to embodiment 2 is characterized by providing the leg portion 53 as a second feature of the present invention.
As described in embodiment 1, the bearing portion 52 of the hinge base 50 is formed by cutting and tilting from the outside of the base 51. Therefore, a sheet metal portion remains after the bearing portion 52 is cut and lifted up is present on the outer side of 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 opposite side of the bearing portion 52 from the base portion 51.
The leg portion 53 has a flange portion 532 having screw holes 533 at the front end thereof, and the flange portion 532 is fastened to the frame member inside the upper panel 11. Thus, the leg portion 53 functions as a reinforcing portion against the 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 after the bearing portion 52 is cut and raised is bent downward as the leg portion 53, but the remaining sheet metal portion may not be bent and may be a reinforcing portion extending outward on the same surface as the base portion 51. However, in the case of forming the leg portion 53, the following two advantages are obtained, and thus are particularly preferable.
(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 is applied to the end portion of the base portion 51. This improves the function as a reinforcement portion against the torsional load applied to the base portion 51. In addition, regarding this effect, if the distance between the base 51 and the screw hole 533 of the flange portion 532 is longer than the distance between the base 51 and the bearing hole 521 of the bearing portion 52, the load applied to the leg portion 53 is preferably reduced.
(2) By cutting the bearing portion 52 and bending the sheet metal portion remaining after the raising downward, the length of the hinge base 50 can be shortened as compared with a case where the sheet metal portion is provided extending outward without bending. In other words, in the case where the length of the hinge base 50 is determined, the distance between the bearing portions 52 can be set longer.
In addition, the hinge base 50 shown in fig. 6 may be configured as follows: a flange portion 532 is provided at the front end of the leg portion 53, which is bent outward, and the flange portion 532 is fastened. That is, the flange portion 532 is fastened to the upper surface of the frame member to which the leg portion 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, it is preferable to dispose the leg portion 53 and the bearing portion 52 at different positions in the longitudinal direction of the hinge base 50 in some cases, as shown in fig. 7 (b).
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 body and the upper cover; a bearing member mounted on the washing machine body and serving as a bearing of the hinge shaft, the bearing member having: a base part having a shape in which an axial direction of the hinge shaft is a longitudinal direction, and being fixed to a frame member inside the washing machine main body; bearing parts formed protruding upward from the base part at two positions at both ends of the base part in the longitudinal direction, and mounted with the hinge shaft; and a reinforcing part extending from both ends of the base 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 tilting from the outside in the longitudinal direction of the base.
