Fig. 25 is a partially cutaway cross-sectional view of an important part of a conventional washing machine described in JP 2000-167290 A. Fig. 26 is a partially cutaway cross-sectional view of the cover body of the conventional washing machine described in JP 2000-167290 A.

In FIGS. 24, 25, and 26, the water tank 242 is supported by the elastic support mechanism 243 as a hanging support and is housed in the main body 241, and the washing and dehydration tank 244 is arranged in the center of the water tank 242 so as to be capable of dehydrating and rotating. At the bottom, the washing and dehydrating tank 244 is equipped with a rotatable stirring blade 245 for stirring. The stirring blade 245 and the washing and dehydrating tank 244 are rotationally driven by a motor 247 fixed to the outer bottom of the water tank 242.

In addition, a top cover 255 is mounted on the uppermost part of the outer box 241. At the center of the top cover 255, there is a laundry inlet 256 facing the washing and dehydration tank 244, and the flat cover 257 is pivotally supported so that the laundry can The upper part of the entrance 256 can be opened and closed freely. The cover 257 is composed of a front cover 259 that a user performs opening and closing operations, and a rear rear cover 258 that is rotatably connected to the front cover 259. The open state of the cover 257 is shown in FIG. 24 as the cover 257a, and the front cover 259a is bent in a parallel state with respect to the rear cover 258a. In addition, the lid body 257 rotates in a slightly vertical state when it is opened, as shown by the lid body 257a.

As shown in FIG. 25, the left and right lateral shaft holes 260 are formed at the rear end of the rear cover 258. On the other hand, the shaft support portion 262 is protruding from the top cover 255, and the shaft 261 can slide in the shaft hole 260. It protrudes laterally freely, and fits the shaft hole 260 of the rear cover 258 with the shaft 261 with a gap, and pivotally supports the cover body 257 to be rotatable.

A rod body 264 with a sector gear portion 269 is integrally formed behind the shaft hole 260 of the rear cover 258, and the sector gear portion 269 formed at the lower end of the rod body 264 engages with the spur gear 271 of the rack 265. The rack 265 constitutes It can move back and forth inside the rear part of the top cover 255. The rack 265 is linked with a shock absorber body 267 having resistance in the horizontal axis direction. The shock absorber body 267 is connected to the piston rod 266 and is fixedly arranged below the rear part of the top cover 255.

In addition, in order to apply a force capable of imparting potential energy to the lid 257 in the opening or closing direction, a toggle spring 270 extending outward from the arm of the torsion coil portion is clamped on the rod 264, and the lid 257 is In the horizontal state, the rod 264 is given the potential energy in the counterclockwise (arrow F) direction with the shaft hole 260 as the center to close the cover 257.

In addition, the shock absorber body 267 has a unidirectional actuation structure that gives resistance only when it moves toward the rear of the piston rod 266 (in the direction of arrow G), and is configured to move toward the front of the piston shown in the direction of arrow C in the opposite direction. , Will not give resistance.

Therefore, when the cover 257 is opened in the direction of arrow A, the rod 264 will be rotated in the B direction with the shaft 261 as the center. Although the rack 265 engaged in the sector gear portion 269 will move in the C direction, there will be no The resistance of the shock absorber body 267. On the other hand, when the cover 257 is to be closed from the open state (E direction), the rack 265 engaged with the sector gear portion 269 will move backward (G direction), bear the resistance of the shock absorber body 267, and move the cover The rotation of 257 is attenuated.

In addition, as shown in JP-A-6-315597, a conventional washing machine is provided with a cover that can open and close the entrance and exit of the laundry, and is supported so as to be rotatable by a hinge structure. In order to improve the operability of the lid, a hinge spring is provided to reduce the opening force of the lid. The hinge spring fixes one end to the hinge part formed on the cover, and installs the other end to the upper frame of the washing machine, thereby imparting rotational force to the cover.

27 and 28 are exploded perspective views of the lid of the conventional washing machine.

When attaching the cover 302 and the upper frame 301, the hinge shaft 305 formed on the upper frame 301 is inserted into the hinge hole 304a formed at the end of the cover 302. A protrusion is formed on the hinge portion 304 of the lid body 302, and the locking portion 303a at one end of the hinge spring 303 is inserted into the mounting hole 304b formed in the protrusion to be locked, and the locking portion 303b at the other end of the hinge spring 303 is inserted to form It is locked in the locking hole 307a of the upper frame 301. In addition, an insertion hole 306 into which the hinge part 304 can be inserted is formed in the upper frame 301, and a recess 307 for supporting the hinge spring 303 is connected to the insertion hole 306 and is formed.

SUMMARY OF THE INVENTION However, in the conventional structure shown in FIGS. 24 to 26, when the lid 257 is closed from opening, the sudden shock sound is eliminated to a certain extent, but when opening from the closed state, except for springs In addition to the resistance of, the resistance to the rotational force generated by the engagement of the gear portion 269 and the rack 265 will also be generated at the same time, which will cause a heavy cover opening operation for the user. Furthermore, when the rear cover 258 is opened and stopped slightly perpendicular to the top cover 255, since there is no resistance of the shock absorber body 267, a violent collision sound will be generated at the stop part of the rear cover 258 and the top cover 255. The problem exists.

In addition, in the conventional example, a structure in which the cover body 257 is divided into the front cover 259 and the rear cover 258 is shown. However, as a recent design trend, a large cover with a single structure is often used in many cases. In this situation, when lifting up to open from the closed state, the force of the toggle spring 270 imparts the opening potential energy plus the inertial force of the whole cover to open it strongly, thereby generating a stronger impact sound or use The discomfort of the above, such a problem exists.

The present invention provides a washing machine that can suppress the impact sound generated when the cover is opened, and can smoothly open and close, and can prevent the shock of the shock absorber holding body by reliably fixing the shock absorber holding body and the cover. Deformation can also improve productivity through stabilization of work.

Furthermore, a space is formed in the cushioning and damping damper holder of the cover, and the damper holder has one end screwed to the cover, and the hooking protrusion is engaged with the engagement portion formed on the cover To fix the other end.

With this structure, the lid body can suppress impact sound and can be closed smoothly. In addition, when the lid is opened, the impact is reduced and the resistance of the shock absorber is reduced by the force of the potential energy imparted by the hinge spring, so as with the opening, the impact sound can be suppressed and the opening can be smooth.

In addition, since the shock absorber holder can be temporarily fixed during assembly, productivity can be improved, and since the shock absorber holder is surely fixed to the cover, the impact caused by the rotating action of the shock absorber can be suppressed. Deformation and damage to improve reliability.

In addition, in the cover structure of other conventional washing machines, the shock absorber holder that accommodates the shock absorber is mounted in a cantilever type, and a large load is applied to the mounting part. Therefore, the weight of the cover may increase, and there is a fear There is a risk that the cover or shock absorber holder may be deformed or damaged.

The invention provides a washing machine, which can prevent deformation and damage of the cover or the shock absorber even if the weight of the cover becomes heavier.

The washing machine of the present invention is configured to include: a top cover placed on the upper part of the washing machine body, a cover that can be opened and closed freely above the top cover by a hinge shaft of the cover, and a cover that imparts potential energy to the opening side of the cover A spring, a spring shaft supporting the cover spring, a rotary impact mitigation and shock absorber that attenuates the rotation of the cover body, and a shock absorber holding body that accommodates the impact mitigation and shock absorber. In addition, the shock absorber holder is provided with mounting ribs for fixing to the cover body by screws or the like, and positioning ribs in a direction slightly opposite to the mounting ribs, and the cover body is provided with screws and the like. The mounting part to be mounted with the mounting rib, and the groove into which the positioning rib can be inserted.

With this structure, the force applied to the shock mitigation and shock absorber when the cover is closed can be absorbed by the mounting ribs and positioning ribs, so that deformation and damage of the cover or shock absorber can be prevented.

In addition, in the conventional structure shown in FIG. 27 and FIG. 28, in order to fix the hinge spring 303, it is necessary to bend the hinge spring 303 from a free length state to an attached state during assembly and attach it to the cover 302. The mounting hole 304b and the locking hole 307a of the upper housing 301 have a problem of poor workability.

The present invention provides a washing machine, which can easily assemble a cover and an upper frame.

The present invention is configured to include: a housing, an upper frame mounted on the upper part of the housing and having a clothing inlet for taking out and putting the laundry at approximately the center, and an upper frame rotatably installed and capable of opening and closing the cover The cover of the clothing inlet. In addition, a cover hinge shaft is provided at the rear of the cover, a hinge part supporting the rotation of the cover is formed at the rear of the upper frame body, a bearing for receiving the cover hinge shaft is provided at the hinge part, and a fixing member is fixed at the rear of the cover body. For sheet metal, the sheet metal has a bent portion that is bent into a slightly vertical direction by bending. Furthermore, a through hole is formed in the bent portion, and a spring shaft that pivotally supports the hinge spring is inserted into the through hole.

Fig. 7A is a transverse cross-sectional view of the main part of the cover of the washing machine in the first embodiment of the present invention. Fig. 7B is an enlarged view of part H of Fig. 7A. Fig. 8 is a longitudinal sectional view of the main part of the cover of the washing machine in the first embodiment of the present invention.

In FIGS. 1, 2, and 3, a top cover 2 is placed on the upper part of the washing machine body 1, and a clothing inlet 30 is formed in the approximate center of the top cover 2, and in order to cover the clothing inlet 30, a hinged A cover 3 that is axially supported by the top cover 2 and can be opened and closed upwardly.

On the top cover 2, an operation display unit 4 for performing various input settings and displaying the setting content is arranged behind the cover 3. A control device (not shown) for controlling the operation of the washing machine is housed inside the operation display unit 4.

The cover body 3 is divided into two upper and lower parts, which are composed of an upper cover body 5 and a lower cover body 6, and a cover window 7 is assembled above the upper cover body 5. In addition, a lid hinge portion 31 is formed on the left and right of the lid lower body 6, and a lid hinge cover 9 is placed on the lid hinge portion 31 in order to cover the internal structure, and the appearance design shape is matched with the lid lower body 6.

The cover body 3 is a kind of which is pivotally supported on the top cover 2 by the cover hinge shaft 10, with the cover hinge shaft 10 as the center of rotation, rotating from the position of the closed state LO to the fully open state LH which is close to a slightly vertical angle. The structure of the location. When closing the lid 3 from the open state LH, after passing the position of the inclined state L1, the shock absorber structure equipped on the lid hinge shaft 10 described later will ease the rotation without applying a violent impact to the lid 3. And reach the position of the occlusion state LO.

As shown in FIG. 4, a cover window 7 is fixed to the upper cover body 5 with a double-sided tape 11, and at the front portion of the upper cover body 5, a cover decorative plate 8 is held and fixed by sandwiching the cover window 7 therebetween.

Between the pair of lid hinge portions 31 of the lid body 3, in order to reduce the opening force of the lid body 3 and improve operability, a hinge mounting plate 14 is arranged, and on the hinge mounting plate 14, there are symmetrically installed There are two hinge springs 12 for directional application of potential energy and two lid hinge shafts 13 for rotation support.

The hinge mounting plate 14 is made of a metal steel plate or the like, and is provided with shaft holes 15 on both side surfaces bent to support the lid hinge shaft 13. The lid hinge shaft 13 penetrates both sides of the shaft hole 15 of the hinge mounting plate 14 for support, and penetrates and holds the coil center of the hinge spring 12 therein. The hinge mounting plate 14 to which the cover hinge shaft 13 and the hinge spring 12 are mounted is tightly fixed with a tapping screw 16 to a screw post 17 integrally formed with the lower body 6 of the cover. The cover 3 is composed of the above parts and has been unitized.

In FIGS. 5, 6, 7A, and 7B, the space portion 6a of the lid hinge portion 31 formed on the left and right sides of the lid body 3 is provided with a shock absorber holder 18 that holds the shock absorber and shock absorber 19, and is The hooking convex portion 18a of the shock absorber holding body 18 is engaged with the groove portion 22 of the cover lower body 6 by hook fitting.

In addition, the cover hinge bearing 24 is tightly fixed to the screw post 26 integrally formed with the top cover 2 with a plurality of mounting self-tapping screws 25.

The shock mitigation and shock absorber 19 will exert resistance to the direction of rotation of the arrow M shown in FIG. 6, and for the rotation relative to the shock absorber shaft 19a, the shock mitigation and shock absorber 19 is enclosed by viscous oil. The resistance produces a damping effect that cushions the rotation of the cover 3 in the closing direction. In this way, the cover 3 will not have impact sound and can be closed smoothly. In addition, when the lid 3 is opened, since the impact resistance and the resistance of the shock absorber 19 are reduced by the force of the potential energy imparted by the hinge spring 12, there is no impact sound and it can be opened smoothly.

A flat surface 19b is formed in the impact mitigation shock absorber, and it is fitted with a gap in the opening hole 18b of the shock absorber holder 18 formed in the same shape to fix the position in the rotation direction.

In addition, the damper shaft 19a is also formed with a damper shaft flat surface portion 19c, and is fitted into the damper bearing hole 24a of the lid hinge bearing 24 with a gap, and the position in the rotation direction is fixed.

To install the unitized cover 3 on the top cover 2, first insert the end of the hinge spring 12 into the spring insertion hole 23 of the top cover 2. Then, for the engagement, the cover 3 is set from a nearly vertical angle The downward bearing is arranged on the top cover 2. This is a free state without the repulsive force of the hinge spring 12, and the spring insertion hole 23 can be easily inserted. Next, insert the hooking convex portion 18a of the shock absorber holder 18 holding the shock absorption shock absorber 19 into the groove 22 of the cover lower body 6, and then slide it outward to make a shock absorber that relaxes the shock absorber 19 The shaft 19a is engaged with the shock absorber bearing hole 24a of the cover hinge bearing 24 provided in the top cover 2, and the shock absorber holder 18 is tightly fixed to the cover lower body 6 by a plurality of self-tapping screws 20. The screw column 21 is used for installation. Finally, install the cover hinge cover 9.

In Fig. 8, when the cover 3 is closed, the resistance of the shock mitigation and shock absorber 19 is large, and the torque in the direction of the arrow M2 in the opening direction of the cover 3 is also added, but the center of gravity of the cover 3 Balance, while stability is off.

Here, although the impact mitigation and the resistance of the shock absorber 19 are in a state in which a torque is applied in the direction in which the shock absorber holder 18 separates from the lower cover body 6, that is, in the direction of the arrow M3, since one end of the shock absorber holder 18 is The self-tapping screw 20 is screwed, and the hooking convex portion 18a at the other end is inserted into the groove 22 of the cover lower body 6, so that both ends of the shock absorber holder 18 are fixed to the cover 3, thereby suppressing the rotation of the shock absorber Deformation and damage caused by the impact of the action. Thereby, the reliability of the lid action can be improved. In addition, during assembly, it can be temporarily fixed by hook fitting before screwing, so that productivity can be improved.

As described above, in this embodiment, a shock absorber holder 18 and a rotary impact mitigation shock absorber 19 are provided. The shock absorber holder 18 is provided in the space portion 6a of the lid hinge portion 31 formed in the lid body 3. The rotary impact mitigation shock absorber 19 attenuates the rotation of the cover 3 by fitting one end to the shock absorber holding body 18 with a gap, and pivotally supporting the other end on the cover hinge bearing 24. In addition, the damper holder 18 is configured such that the front end is screwed and fixed to the cover with a tapping screw 20, and the hooking convex portion 18 a formed at the rear end is inserted and fixed to the groove 22 formed in the cover 3. With this structure, the lid body 3 does not have a crash sound and can be closed smoothly. In addition, when the lid 3 is opened, the impact resistance and the resistance of the shock absorber 19 are reduced by the potential energy imparted by the hinge spring 12, so there is no impact sound and can be opened smoothly.

Furthermore, since the shock absorber holder 18 can be temporarily fixed during assembly, productivity can be improved, and since the shock absorber holder 18 is surely fixed to the cover 3, it is possible to suppress the rotation of the shock absorber. Deformation and damage caused by impact force, thereby improving reliability. (Second Embodiment)

Fig. 9 is an external perspective view of a washing machine in a second embodiment of the present invention. Fig. 10 is a partially cutaway side view showing the opening and closing action of the lid of the washing machine in the second embodiment of the present invention. Fig. 11A is a cross-sectional view of the main part showing the structure of the lid portion of the washing machine in the second embodiment of the present invention. Fig. 11B is a cross-sectional view of the main part showing the opened state of the lid of the washing machine in the second embodiment of the present invention.

As shown in the external view of FIG. 9, a top cover 52 is placed on the upper part of the washing machine body 51, a cover 53 is detachably arranged at the center of the upper surface of the top cover 52, and a control unit for controlling the operation of the washing machine is disposed in front of the top cover 52 Control board 55.

The cover body 53 is configured to form a slightly rounded planar shape with excellent design and aesthetics, and has a slightly rounded transparent window 54 in the central part so that the inside can be visually seen. When the user wants to open the cover body 53, it will be formed in The recess 56 in the front of the top cover 52 is raised.

Figure 10 shows the opening and closing operation of the lid 53. The lid 53 is a structure that takes the shaft hole 57 as the center of rotation and opens from the closed state L0 to the fully opened open state LH that is close to a slightly vertical angle. .

In the opening operation of the lid body 53 of the user, the lid body 53 can be lifted from the closed state L0 to the open state LH with a slight force by the force of the potential energy imparted by the lid spring 69 described later.

When the LH is to be closed from the open state, slightly close the lid 53 and remove the hand, the lid 53 will close due to its own weight, but the potential energy of the lid spring 69 and the shock and shock absorber 72 described later will alleviate The turning action of closing prevents the lid body 53 from applying a violent impact to the top lid 52 and closes to the position of the closed state L0.

The shock mitigation and shock absorber 72 does not work when the cover 53 is opened, and only works when the cover 53 is closed. Therefore, when the cover body 53 is opened, it can be lifted with a slight force, and when the cover body 53 is closed, the rotating action can be relaxed and the cover body 53 can be slowly closed.

As shown in FIGS. 11A and 11B, the cover body 53 is formed by superimposing a cover body 58 with a substantially circular planar shape and a convex spherical cross-section to support the outer peripheral portion of the cover body 58 from below to form a slightly doughnut-shaped planar shape. The lower cover frame 59 and the outer peripheral portion of the main body 58 covered from above are formed by a cover frame 60 whose planar shape is a horseshoe shape. In particular, the cover main body 58 is formed of, for example, a transparent resin member. The user can visually confirm The state of the laundry inside.

A drop portion 61 is formed at the rear of the cover body 58, and a cover 62 on a flat plate formed of a non-transparent material is installed from above as a connecting component of the horseshoe-shaped cover frame 60, and is designed to be considered The structure of the internal structure described later cannot be seen from the cover body 58 of the transparent resin member.

A hinge portion 63 is integrally formed at the rear of the cover lower frame 59 and constitutes a shaft hole 57 and the like at the center of the opening and closing rotation motion of the cover body 53.

When the cover lower frame 59 is installed, it is formed in the space 90 behind the cover body 58. The cover spring 69, the spring shaft 80, and the cover reinforcement plate 79 are provided inside. The spring shaft 80 supports the cover spring 69 and the cover reinforcement The plate 79 is pressurized by a spring pressure from one end of the cover spring 69, is made of a metal steel plate or the like, and is fixed to the cover lower frame 59.

The other end 91 of the cover spring 69 points downward, and is inserted and clamped to the top cover reinforcing plate 76 installed on the top cover 52 from above.

In FIG. 11A showing the closed state of the lid body 53, the lid spring 69 adds a repulsive force around the rotation center of the spring shaft 80 in a clockwise direction (the lid hinge shaft 77 at the rotation center of the lid body 53 is also the same). The repulsive force is a force to bend the cover spring 69 slightly by 90 degrees to open the cover 53 through the cover reinforcement plate 79. At this time, since the repulsive force of the lid spring 69 to open the lid is set to be smaller than the increase caused by the weight of the lid body 53 itself, the lid body 53 is kept in the closed state.

In this configuration, in the open state where the lid body 53 is lifted to be slightly vertical and opened as shown in FIG. 11B, the lid spring 69 is in a state of extending into a substantially free shape that is slightly vertical, and it is not affected by a certain amount of potential energy. Let the lid fall.

In recent years, the lid body 53 is also illustrated in FIGS. 11A and 11B. The lid body 58 of a transparent resin member is combined with the lid lower frame 59 or the lid upper frame 60 to become a relatively strong and heavy structure. In order to reduce the load when the lid body 53 is opened, the lid spring 69 is configured to have the strongest spring force in the closed state where the lid body 53 is closed. As mentioned above, in order to support a strong spring force, the cover reinforcement plate 79 is made of a horizontally long metal steel plate or the like. It is configured so that one end of the cover spring 69 does not directly apply spring pressure to the cover lower frame 59 , And is configured to reinforce the rear portion of the lower cover frame 59 so as to withstand the cover opening and closing operation.

Although it is configured as described above to strengthen the spring force of the lid spring 69 against the weight of the lid body 53, there is no large force applied to the lid spring 69 when the lid is opened. Therefore, there will be a large amount of force in the middle of closing the lid. The force is applied to the shock absorber holding body 81.

Behind the cover setting portion 70 of the top cover 52 is formed a top cover side shaft support hole 71, a top cover reinforcing plate 76, and a shock absorber bearing structure 73 for alleviating impact. The top cover side shaft support hole 71 corresponds to the cover lower frame The shaft hole 57 of the body 59, the top cover reinforcement plate 76 is composed of a steel plate having a cover spring insertion hole 75 for inserting and holding the cover spring 69, and the shock absorber receiving structure 73 has a shock absorber 72 that can be mounted The slightly Y-shaped receiving portion 74.

The cover spring 69 is as illustrated in FIG. 11B. Before the cover body 53 is assembled to the top cover 52, the other end 91 is directed downward in a free state with almost no spring repulsive force, and in this state, the other end 91 is inserted and snapped into the configuration The top cover reinforcing plate 76 of the top cover 52.

Assemble the cover 53 to the top cover 52 from above, and insert and hold the cover hinge shaft 77 in the shaft hole 57 and the top cover side shaft support hole 71 from the horizontal direction, whereby the cover body 53 will be configured to be able to be mounted on the top cover 52 open and close freely.

In the exploded view of the cover body in FIG. 13, the cover body 58 having a substantially circular planar shape has a horseshoe-shaped drop portion 78 formed around it, and a drop portion 61 is formed behind it, and the planar shape of the cover body is roughly horseshoe-shaped. The frame body 60 and the cover 62 on the flat plate are respectively embedded or fixed by welding, adhesion or other methods.

In addition, the slightly doughnut-shaped lid lower frame 59 is tightly fixed to a boss 83 integrally formed on the inner surface of the horseshoe-shaped drop portion 78 with a plurality of mounting screws 82, and comes from below the lid body 58 installation.
