The basic structure of the washing machine 100 will be described with reference to fig. 1 and 2.

The washing machine 100 includes an outer frame 110 constituting a housing, an upper cover 300 constituting the housing, a cover 500, and an operation display unit 400 as an operation display part. The upper cover 300 forms an inlet 310 for putting clothes and is fixed to the upper portion of the outer frame 110. A washing tub 200 constituting a storage part is built in the outer frame 110. The washing tank 200 is a bottomed cylindrical shape having an upward opening, and is disposed so that its opening faces the inlet 310.

The lid 500 is formed of a front lid 510, a rear lid 520, and a folding lid shaft portion 530, and the lid 500 is openably and closably provided on the upper cover 300 so as to cover the inlet 310. The front cover 510 and the rear cover 520 are pivotably connected to each other with a folding cover shaft portion 530 as a fulcrum. The rear cover 520 is rotatably coupled to the rear of the upper cover 300 as a housing. A grip 513 is formed on the front cover 510, and the grip 513 is configured to be grasped by a user inserting a hand. The user can open the lid body 500 by gripping the grip 513, lifting the front lid body 510 upward, and pressing it rearward. As shown in fig. 2, the lid body 500 in the open state is folded so that the folded lid body shaft portion 530 is positioned above and is positioned at the rear upper portion of the upper cover 300.

The operation display unit 400 as an operation display portion includes a display 411, operation buttons 412, and a unit cover 421 in which the display 411 and the operation buttons 412 are arranged. The user can confirm the washing operation information displayed on the display 411 and set an instruction related to the washing operation using the operation button 412. The operation display unit 400 is disposed at the rear of the upper cover 300 as a housing. By positioning the operation display unit 400 behind the input port 310, it is easy for the user to input laundry into the input port 310 or take laundry out of the input port 310. The width of the operation display unit 400 is substantially the same as the width of the cover 500 and the upper cover 300 as a housing. The long side of the operation display unit 400 as the operation display unit and the rear cover 520 are configured not to have a height difference when the cover 500 is in the closed state. Thus, when the cover 500 is in the closed state, the operation display unit 400 and the cover 500 form a flat plane. When the cover 500 is in the open state, the state shown in fig. 2 is achieved, and the cover 500 is positioned behind the operation display unit 400. Therefore, even when the cover 500 is in the open state, the user can visually confirm the display 411 and the operation buttons 412.

The structure of the cover 500 will be described with reference to fig. 3. The front cover 510 is configured by disposing a front cover top surface portion 511, a front cover outer peripheral portion 512, and a front cover back surface portion 514 from top to bottom. The front cover outer circumferential portion 512 is provided so as to be sandwiched between the front cover top surface portion 511 and the front cover back surface portion 514, but the side surface of the front cover outer circumferential portion 512 is configured so as to be visually recognized from the outside.

The rear cover 520 includes a rear cover top surface portion 521, a rear cover outer peripheral portion 522, and a rear cover rear surface portion 524. The rear cover reverse surface portion 524 is provided below the rear cover top surface portion 521. The rear cover outer peripheral portion 522 is disposed on the side surface of the rear cover top surface portion 521, and is provided at two positions on the left and right.

A part of the folding lid shaft portion 530 is formed at each of the rear end portion of the front lid back surface portion 514 and the front end portion of the rear lid back surface portion 524. The folded cover shaft portion guide plate 604 is fixed to a part of the folded cover shaft portion 530 at the rear cover reverse portion 524 with screws. The front cover 510 and the rear cover 520 are coupled to be rotatable by engaging a part of the folded cover shaft 530 on the front cover reverse surface portion 514 with a part of the folded cover shaft 530 on the rear cover reverse surface portion 524 and covering the part with the folded cover shaft guide plate 604.

The hinge section 700 shown in fig. 7 will be described as a cross-sectional view with reference to fig. 4 as an exploded perspective view. The hinge portion 700 is configured by combining the lid body 500, the upper cover 300 as a housing, and the respective members at the operation display unit 400 as an operation display portion. The hinge 700 mainly includes a cover rotation shaft 525, a cover rotation bearing 321, and a cover rotation shaft guide plate 602, and the hinge 700 is rotatably connected to the cover 500.

Next, the structure of the cover rotation shaft 525 will be described with reference to fig. 3 and 4. The rear cover hinge cover portion 523 as a cover portion is a substantially semicircular plate-shaped member extending rearward of the back surface of the rear cover 520 and protruding downward. A lower rotation shaft 525a of the lid rotation shaft 525 formed in a substantially semi-cylindrical shape is provided on the inner surface of the rear lid hinge cover portion 523. An upper rotating shaft 525b of the lid rotating shaft 525 formed in a substantially semi-cylindrical shape is provided on the rear lid outer peripheral portion 522. An upper rotation shaft 525b of the lid rotation shaft 525 at the rear lid outer peripheral portion 522 and a lower rotation shaft 525a of the lid rotation shaft 525 at the rear lid reverse surface portion 524 are fixed with screws to form the lid rotation shaft 525. In addition, in order to secure the strength of the cover rotation shaft 525, a hinge reinforcing plate 605 is provided between the upper rotation shaft 525b and the lower rotation shaft 525a of the cover rotation shaft 525. The hinge reinforcing plate 605 is fixed to the lower rotation shaft 525a of the cover rotation shaft 525 and the rear cover reverse surface portion 524 by screws.

Fig. 5 is a plan view showing a structure around a hinge portion of a lid body of the washing machine according to the present embodiment.

In fig. 4 and 6, the cover rotation shaft 525 includes a cover rotation shaft recess 541. Upper cover 300 as a housing includes cover rotation bearing 321 and cover rotation shaft protrusion 322. The cover rotation shaft 525 is disposed on the semicircular cover rotation bearing 321 in a state where the cover rotation shaft convex portion 322 is inserted into the cover rotation shaft concave portion 541. This supports the body portion and the distal end portion of the lid rotation shaft 525. Further, a lid rotation shaft guide plate 602 is disposed on the lid rotation shaft 525, and the lid rotation shaft guide plate 602 is fixed to the upper cover 300 by a hinge screw 603.

The upper cover 300 as a housing is provided with a substantially semicircular concave portion 320 recessed downward at a position corresponding to the rear cover hinge cover portion 523 as a cover portion. The rear cover hinge cover portion 523 is received in the concave portion 320 and rotated, so that the cover 500 does not protrude laterally from the upper cover 300.

Next, the relationship between the hinge portion 700 and the operation display unit 400 will be described. The unit cover 421 of the operation display unit 400 is fixed to the upper cover 300 as a housing by fitting the front side thereof with a claw and fixing the rear side thereof with a screw. The cover rotation axis cutout 431 provided in the unit cover 421 is a semicircular cutout, and forms a circular hole together with the cover rotation bearing 321. The unit cover 421 is disposed such that the lid rotation shaft notch 431 abuts on the lid rotation bearing 321. That is, the cover rotation shaft 525 constituting the hinge portion 700 is disposed so as to penetrate a hole formed by the cover rotation shaft notch 431 and the cover rotation bearing 321. Therefore, most of the hinge portion 700 is built in the unit cover 421. The end portion not built in the unit cover 421 is covered with the rear cover hinge cover portion 523 as a cover portion, and is not visually confirmed from the outside. In other words, the hinge 700 that supports the lid body 500 so as to be openable and closable is located below the operation display unit 400 as the operation display unit.

Differences in the hinge section 700 between the closed state and the open state of the lid body 500 will be described with reference to fig. 7 and 8. Although reference numerals of the hinge unit 700 are not shown in fig. 7 and 8, the hinge unit 700 includes the lid rotation bearing 321, the lid rotation shaft 525, the lid rotation shaft guide plate 602, the hinge unit screw 603, and the hinge reinforcing plate 605 disclosed in any one of fig. 7 and 8. The hinge portion 700 includes a spring receiving portion 324, a spring 601, a stopper receiving convex portion 543, and a stopper receiving surface 325.

Fig. 7 shows the configuration of the hinge part 700 in the closed state. In fig. 7 and 8, the spring housing 324 constituting the hinge 700 is formed in the upper cover 300 and is disposed at the rear lower portion of the lid body rotation shaft 525. The spring 601 is disposed inside the spring housing 324. One end of the spring 601 is fixed to a spring mounting groove 323 provided in the upper cover 300, and the other end is fixed to a spring mounting hole 542 formed in the cover body rotation shaft 525. The spring 601 is compressed in the closed state and biases in a direction to become the open state. When the user lifts the lid body 500 upward, the urging force of the spring 601 acts in the opening direction. The user can easily put the cover 500 in the open state.

A stopper receiving projection 543 is provided on the upper portion of the cover rotation shaft 525, and a stopper receiving surface 325 is provided on a side surface of the spring housing portion 324. In the closed state, the stopper receiving projection 543 is not in contact with the stopper receiving surface 325.

Fig. 8 shows the configuration of the hinge part 700 in the opened state. Since the stopper receiving projection 543 is in contact with the stopper receiving surface 325, the lid body 500 cannot be further opened. With this structure, the lid body 500 can be held at a constant opening angle.

The operation of the hinge section 700 of the present embodiment has been described above.

The lid rotation shaft 525 of the present embodiment is formed in a cylindrical shape. The lid rotation shaft 525 can stably support the lid 500 on the upper cover 300 by coming into contact with the semicircular lid rotation bearing 321. The rear lid hinge cover portion 523 exposed to the outside is not subjected to much stress, and therefore can be made thin.

The hinge portions 700 of the present embodiment are disposed at two locations on the left and right sides of the upper portion of the upper cover 300, which is a housing. A spring 601 is disposed at the rear lower portion of the cover rotation shaft 525. This allows the hinge section 700 to be reduced in size, and therefore, the space inside the cell cover 421 for operating the display substrate 422 (see fig. 6) is not lost.

Since the width of the operation display unit 400 as the operation display unit of the present embodiment can be made substantially the same as the width of the cover 500 and the upper cover 300 as the housing, the operation buttons 412 and the display 411 can be arranged widely. This can increase the number of operation buttons 412 or increase the interval between the operation buttons 412, thereby improving operability.

The cover rotation shaft 525 of the hinge portion 700 of the present embodiment is inserted into the hole formed by the cover rotation shaft notch 431 and the cover rotation bearing 321, so that the hinge portion 700 can be positioned below the operation display unit 400 as the operation display portion and covered by the unit cover 421 of the operation display unit 400. Therefore, a special cover for covering the hinge portion 700 is not provided. This can reduce the number of parts and the number of assembly steps.

The hinge portion 700 of the present embodiment is housed inside the unit cover 421, so that the hinge portion 700 cannot be visually confirmed from the outside even when the lid body 500 is in the open state. This makes it difficult for the user to feel the presence of the hinge portion 700, and the quality of the appearance when the lid body 500 is opened is not lost. Since the hinge portion 700 and the operation display substrate 422 are integrally covered with the unit cover 421, there is no gap or unevenness on the surface of the unit cover 421. Therefore, even if the detergent or the like is sprinkled, the cleaning can be immediately performed.

As described above, in the present embodiment, washing machine 100 includes outer frame 110 and upper cover 300 constituting a housing, washing tub 200 constituting a storage portion, lid 500, hinge 700, and operation display unit 400 as an operation display portion. The upper cover 300 has an inlet 310 for putting clothes. The washing tub 200 is opened upward and is built in the outer frame 110. The cover is provided to cover the upper side of the inlet 310. The hinge 700 supports the lid 500 to be openable and closable. The operation display unit 400 is provided behind the input port 310, and sets and displays instructions related to the washing operation. The width of the operation display unit 400 is substantially the same as the width of the upper cover 300 as a housing, and the hinge portion 700 is located below the operation display unit 400.

Thus, a special cover for covering the upper portion of the hinge 700 is not required, and the hinge 700 is not exposed to the outside even when the cover 500 is opened. Therefore, the ease of maintenance around the operation display unit 400 can be improved, and the appearance quality when the lid body 500 is in the open state can be improved.

As in the present embodiment, the hinge 700 may have a cover rotation shaft 525 provided at the rear portion of the cover 500, a cover rotation bearing 321 for supporting the cover rotation shaft 525, and a cover rotation shaft guide plate 602.

This allows the hinge 700 to be housed inside the operation display unit 400, and the lid 500 to be supported by the upper cover 300 only by the left and right hinge 700. In addition, the rear cover hinge cover portion 523 that covers the side surfaces of the hinge portion 700 can be made thin. Therefore, the user does not easily feel the presence of the hinge part 700, and the appearance quality of the washing machine 100 is improved.

As in the present embodiment, the cover rotation shaft 525 may have a substantially cylindrical shape extending from the rear cover hinge cover portion 523 toward the inside of the operation display unit 400, and may be configured to pass through a hole formed by the cover rotation shaft cutout portion 431 and the cover rotation bearing 321.

This allows the hinge 700 to be housed inside the operation display unit 400, and the lid 500 to be supported by the upper cover 300 only by the left and right hinge 700. In addition, the rear cover hinge cover portion 523 that covers the side surfaces of the hinge portion 700 can be made thin. Therefore, the user does not easily feel the presence of the hinge part 700, and the appearance quality of the washing machine 100 is improved.

As in the present embodiment, the lid 500 may have a rear lid hinge cover portion 523 formed in a substantially semicircular plate shape extending rearward and protruding downward, and the lid rotation shaft may be provided on the inner surface side of the cover portion. The upper cover 300 may be configured to have a substantially semicircular concave portion 320 recessed downward at a position corresponding to the rear cover hinge cover portion 523, and the rear cover hinge cover portion 523 may be configured to be received in the concave portion 320 and rotated.

This makes it possible to prevent lid 500 from protruding laterally from upper cover 300, and to improve the appearance quality without increasing the width of washing machine 100.
