Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a washing machine.

[0002]

2. Description of the Related Art For example, as one of the conventional washing machines, a washing tub (for example, comprising an inner tub and an outer tub) for washing and dewatering is disposed on the front surface of a rectangular cylindrical outer frame. There is a washing machine in which an opening communicating with the inside is provided, and the opening is covered with a removable cover. In such a washing machine,
By providing an opening on the front side, inspection and inspection of internal parts
Repairs can be performed without moving the washing machine, improving serviceability.

[0003]

(1) In the above washing machine, a screw through hole is formed in the cover, a screw mounting hole is formed in the outer frame, and a metal screw is inserted through the through hole. The cover is fixed to the outer frame by being attached to the attachment hole. In some cases, hooks such as claws are formed on the cover, fixed to some extent by a structure that hooks and locks on the outer frame, and finally fixed with screws so that the hooks do not come off.

[0004] However, since the outer frame is made of metal and has a small material thickness, it is not possible to obtain a sufficient threading allowance. For this reason, there is a problem that the screws are easily loosened due to vibrations during the washing operation. In addition, there is also a problem that if the screw is tightened strongly when screwing, the screw tends to be ridiculous.

(2) In the above-mentioned washing machine, a structure in which the washing tub is inclined to the front side to make it easy to take out the laundry is also conceivable. And in such a case, the upper part of the washing tub comes out a little earlier than before, so the shape of the cover, whose front is all flat, was adjusted so that only the upper part of the front avoids the washing tub. It is conceivable to have a shape that expands forward. In this case, the entire outer frame does not need to be large, and the washing machine can be installed in the same waterproof pan as before.

A cover having a shape in which a specific portion swells forward is used not only for avoiding a part of the outer frame projecting forward but also for a design purpose. Conceivable.

[0007] However, such a cover is manufactured by processing a flat steel plate. However, the completed cover is formed on the inner side (back side) near the boundary between the flat part and the part protruding forward. ), The width becomes slightly narrower near the boundary. (At the boundary, the sides on both sides are slightly inward and become constricted.) Therefore, if such a cover is attached to the outer frame as it is, the following problem occurs. That is, while the line on the side surface of the outer frame is straight, the line on the side surface of the cover is not straight, which impairs the appearance. Also, when the front part near the boundary is pushed by hand from the front, the warp easily returns. In other words, the front part is easily pressed by hand when pressed.

(3) Further, in the above-mentioned washing machine, if the laundry is not biased at the time of starting dehydration, the washing tub shakes greatly. In this case, if the shaking is too severe, dehydration is stopped by being detected by a vibration detection lever or the like, but sometimes the vibration is not detected. When the laundry rises, water in the laundry is soon drained, the bias becomes smaller, and the laundry sometimes rotates normally at a high speed without hitting the outer frame.

[0009] However, since the washing tub hits the outer frame, a certain impact force is applied to the outer frame. In particular, when this impact force is applied to the cover attached to the outer frame, the fixing structure portion such as a screw is attached. And the screws may be loosened or come off, which may cause problems.

According to the present invention, an opening is provided on one side surface of the outer frame,
Such a problem is solved in a washing machine further provided with a cover that removably covers the opening.

[0011]

According to the first aspect of the present invention, a washing tub for washing and dewatering is disposed inside, and one side has an opening communicating with the inside. A metal outer frame whose surface is painted, a resin pedestal that is arranged below the outer frame and supports the outer frame, and covers the opening of the outer frame, a metal surface that is painted And a cover made of a metal, and a screw through hole is formed in a lower portion of the cover, a screw mounting hole is formed in the pedestal, and a metal screw is inserted through the through hole. By attaching to the mounting hole, while fixing the lower part of the cover to the pedestal, while the cover and the pedestal are fixed by the screw,
The through hole is configured such that the screw contacts an inner peripheral edge portion of the through hole.

In this configuration, the lower part of the cover is screwed,
Since it is attached to a resin pedestal that is relatively thick and can easily form mounting bosses etc., it is possible to take a large amount of screwing allowance, and to prevent screws from becoming loose or stupid Can be prevented.

Further, since the cover is fixed across the outer frame and the pedestal, the cover is reinforced and the fixing between the pedestal and the outer frame is strengthened.

Further, when the cover and the pedestal are fixed by screws, the screws are brought into contact with the inner peripheral portion of the unpainted through-hole, so that the charging portion of the washing machine and the washing machine At the time of an insulation resistance test with respect to the entire outer frame (including the cover) and a withstand voltage test, the test can be easily performed by applying a terminal of the tester to a screw head.

Further, as in the configuration according to claim 2, the inner diameter of at least one direction of the through hole is made smaller than the outer diameter of the screw, so that the screw contacts the inner peripheral edge portion of the through hole. In this case, the screw has a small inner diameter and pushes through the screw, so that the screw can be surely brought into contact.

In order to make the contact better, it is desirable that the inner diameter of the through hole is smaller than the root diameter of the screw.

Further, as in the configuration according to a third aspect, the through hole has a long hole shape having an inner diameter larger than an outer diameter of the screw and an inner diameter smaller than the outer diameter of the screw. With the configuration that contacts the peripheral portion, in the direction where the inner diameter is larger than the outer diameter of the screw, it is possible to cope with a slight deviation due to a dimensional error between the through hole and the mounting hole of the pedestal. When the cover is mounted on the pedestal, the through holes and the mounting holes can be made as easy as possible.

Further, as compared with the case where the through hole is circular and all the inner diameters are smaller than the outer diameter of the screw, the force for expanding the hole when penetrating the screw is small, and the screw is easily fixed.

According to a fourth aspect of the present invention, there is provided an outer frame in which a washing tub for washing and dewatering is disposed, and which has an opening communicating with the inside on one side, and the opening of the outer frame. In a washing machine having a metal cover that covers a portion, a front plate having a flat portion and a bulging portion that bulges forward from the flat portion, and both side ends of the front plate are moved rearward. The outer frame, on both sides of the opening, a flange plate to which the cover is attached, further in the flange plate,
When the cover is attached to the outer frame, a portion of the cover facing the vicinity of the boundary between the flat portion and the bulging portion has a lower end of the side plate when the cover is attached to the outer frame. A projection is provided which abuts on the inside of the portion and pushes a portion near the boundary of the side plate outward to a desired position.

In this configuration, the inner side is slightly warped in processing,
The portion near the boundary between the flat portion and the bulging portion on the side surface of the cover, which has become slightly narrower, is pushed outward by the convex portion when the cover is attached to the outer frame, and the warpage is corrected.

Therefore, the line on the side surface of the cover is straightened, and the appearance is not impaired. Also, even if the part near the boundary is pushed by hand from the front, it is difficult for the user to stick.

According to a fifth aspect of the present invention, there is provided a rectangular cylindrical outer frame in which a washing tub for washing and dewatering is suspended and supported inside, and one side has flanges at both ends. And an opening communicating with the inside at the center, and an outer frame reinforced at the upper end of each corner with a reinforcing member, and attached to the flange of the outer frame to cover the opening. In the washing machine provided with a cover, when the washing tub swings to the cover side, before the washing tub hits the cover, an abutting member that hits the flange portion is provided at an upper portion of the washing tub. It is provided so as to protrude toward the flange portion.

When the washing tub swings due to the bias of the laundry at the start of dehydration, even if the washing tub swings in the direction of the cover,
Before the washing tub hits the cover, the abutment member provided on the washing tub has its corners reinforced by the reinforcing member and hits the upper part of the flange portion in a strong state. Therefore, a large impact force is not applied to the cover, and it is possible to prevent a fixing member such as a screw fixing the outer frame and the cover from being loosened or detached.

According to a sixth aspect of the present invention, when a portion of the abutting member that hits the flange portion is provided with a cushioning member, the impact force when hitting the flange portion is reduced. Thus, the load on the flange portion is reduced. Furthermore, the impact noise is reduced.

Now, the outer frame 21 of the front plate 22 and the pedestal 24
Hereinafter, the structure for attachment to the vehicle will be described with reference to FIGS. 2 and 4 to 6.

The left and right mounting flange pieces 2 of the front plate 22
A hook portion 22f (only a part is shown) is provided at an inner end portion of the inner portion 24 at three locations, that is, an upper portion, a central portion, and a lower portion. The hook 21f is shaped like a hook with its tip directed upward. The hook 22f is hooked on a locking hole 21f provided at an upper portion, a center portion, and a lower portion of the extension plate 21a of the outer frame 21, and
The front plate 22 is attached to the outer frame 21. Specifically, after inserting the hook portion 22f into the locking hole 21f, the front plate 22 is slid upward. Then, the tip of the hook portion 22f is caught on the upper edge of the locking hole 21f, and the front plate 22 does not come off in the forward direction.

After the front plate 22 is locked to the outer frame 21, in this state, the lower end of the front plate 22 is fixed to the pedestal 24 with a metal screw 80.

That is, on the lower end surface of the front plate 22, right and left fixing flange pieces 22c are provided. The fixing flange piece 22c is provided with a through hole 22d through which the screw 80 passes. The through hole 22d has a vertically long elliptical shape, the horizontal inner diameter X is slightly smaller than the root diameter of the penetrating screw 80, and the vertical inner diameter Y is considerably larger than the outer diameter of the screw 80.

On the other hand, mounting bosses 24e for screws 80 are integrally formed on the front surface of the pedestal 24 on the left and right sides, and mounting holes 24d are formed in the mounting boss 24e. Mounting boss 2
4e, that is, the length of the mounting hole 24d is longer than the insertion length of the screw 80, and the margin of the screw 80 is sufficiently large. The mounting hole 24d has a circular shape, and the inner diameter is slightly smaller than the root diameter of the screw 80, like the inner diameter next to the through hole 22d.

A tapping screw is used as the metal screw 80. Therefore, it is not necessary to form a female screw portion in the mounting hole 24d.

The positions of the through hole 22d and the mounting hole 24d are as follows.
When the hook 22f is locked in the locking hole 21f, the front plate 22 is locked.
Are attached to the outer frame 21 in a state where they are attached to each other. After the holes are aligned, the lower portion of the front plate 22 is fixed to the pedestal 24 by attaching the screw 80 to the mounting hole 24d through the through hole 22d.

At this time, since the horizontal inner diameter of the through hole 22d is smaller than the root diameter of the screw 80, the screw 80 is
When the screw 80 is screwed, the body of the screw 80 comes into contact with the uncoated inner peripheral portion of the through hole 22d (the inner wall of the hole).

As described above, in the above mounting structure, the outer frame 2
As compared with the method in which the screw is fixed to 1, the screw allowance can be increased, and the screw can be prevented from being loosened or ridiculous.

The front plate 22 and the pedestal 24 are
In this state, the screw 80 comes into contact with the inner peripheral portion of the unpainted through-hole 22d, so that the insulation between the charged portion of the washing machine 1 and the housing 2 of the washing machine 1 is provided. At the time of the resistance test or the withstand voltage test, the test can be easily performed by applying the terminal of the tester to the head of the screw 80.

Furthermore, by making the lateral inner diameter of the through hole 22d smaller than the root diameter of the screw 80, the screw 80 pushes the hole and penetrates, so that the screw 80 is securely inserted into the inner peripheral edge portion. Can be contacted.

Further, since the vertical inner diameter of the through hole 22d is sufficiently larger than the outer diameter of the screw 80, in this direction, it is possible to cope with a slight deviation due to a dimensional error between the through hole 22d and the mounting hole 24d. In addition, it is possible to easily match the through hole 22d and the mounting hole 24d as much as possible while ensuring the easiness of the insulation resistance test and the withstand voltage test.

Further, as compared with the case where the through hole 22d is circular and the inside diameter is smaller than the root diameter of the screw 80, the force for expanding the hole when penetrating the screw 80 is small, and the screwing is facilitated.

The front plate 22 is manufactured by processing a flat steel plate. However, the finished front plate 22 has an inner side near the boundary between the bulging portion 22b and the lower flat portion 22a in terms of manufacturing. (Back side) and the width is near the boundary (A in FIG. 2).
), The state becomes slightly narrower. In other words, the sides on both sides are slightly inward at the boundary portion, and are in a constricted state. (If drawn extremely, a state as shown in FIG. 2B is obtained.) In the washing machine 1 according to the embodiment of the present invention, the front plate 22 is attached to the outer frame 21.
Has a structure that eliminates such warpage of the front plate 22 when attached to the front panel 22. This structure will be described with reference to FIGS.

In both the left and right extension plates 21a of the outer frame 21, a projecting portion 81 projecting forward is formed at a position slightly above the locking hole 21f at the center. The convex portion 81 has a steep inclined surface 81a when facing outward, and no gentle inclined surface 81b when facing inward, and has a triangular shape when viewed from above.

When the front plate 22 is attached to the outer frame 21, the portion where the convex portion 81 is formed is opposed to the vicinity of the boundary between the upper bulging portion 22b and the lower flat portion 22a of the front plate 22. Part.

When the front plate 22 is attached to the outer frame 21 as described above, in a portion where the lateral width is reduced, the inside of the lower end of the side plate 223 of this portion, that is, the mounting flange piece 2
As shown by the solid line from the broken line in FIG. 7, the side plate 223 is pushed outward by being guided by the steep inclined surface 81 a of the convex portion 81 and moved outward. Is corrected.

Therefore, the line on the side surface of the front plate 22 is straightened, matches the line on the side surface of the outer frame 21, and does not impair the aesthetic appearance. Also, even if the part near the boundary is pushed by hand from the front, it is difficult for the user to stick.

When the front plate 22 is pressed, the hooks 22f are positioned outside the locking holes 21f when the front plate 22 is attached to the outer frame 21, as shown in FIG. 21 g of folded pieces provided on the side and the outer side of the side
In this case, the movement of the side plate 223 to the outside is restricted, so that the movement is further suppressed.

FIG. 9 shows a construction in which the washing tub 3 does not hit the front plate 22 and does not give a large shock even if the washing tub 3 is greatly shaken due to the unevenness of the laundry at the start of the spin-drying operation. This will be described with reference to FIG.

The front left and right sides of the upper portion of the outer tank 31, that is, the outer frame 2
An abutment member 82 is attached to a portion near the first extension plate 21 a with a screw 83. The abutting member 82 includes a case 84 having mounting bosses 84a for screws 83 at both ends and a recess 84b formed at the center, and a recess 84b.
And a rubber body 85 as a buffer member housed therein.

A rib 84c for preventing the rubber body 85 from being displaced is provided at two places at the center of the bottom of the recess 84b.
The rubber body 85 has cutouts 85c corresponding to the ribs 84c.
Is provided. By fitting the rib 84c into the notch 85c, the rubber body 85 housed in the recess 84b is formed.
Misalignment is prevented. Also, triangular reinforcing ribs 84d are provided at four places on the upper and lower side surfaces of the case 84 so that the case 84 does not bend up and down due to an impact at the time of collision of the abutting member 82 with the extension plate 21a. ing.

The tip of the rubber body 85 protrudes forward from the case 84 in the state of being housed in the recess 84b. The distance between the abutting member 82 and the extension plate 21a is determined by the outer tub 3
1 is shorter than the distance between the front end portion and the front plate 22.

Thus, at the time of starting dehydration, the laundry tub 3 shakes due to the bias of the laundry, and even if the laundry tub 3 swings in the direction of the front plate 22,
The abutment member 82 contacts the upper portion of the extension plate 21a. Extension board 2
The upper part of 1a is in a strong state, with the corners reinforced by the receiving member 28.

Therefore, a large impact force is not applied to the front plate 22, and the screws fixing the outer frame 21 and the front plate 22 can be prevented from being loosened or removed.

Further, the tip end of the abutting member 82 is
Therefore, the impact force when hitting the extension plate 21a is weakened, and the load on the extension plate 21a is reduced. Furthermore, the impact noise is reduced.

In the above embodiment, the washing machine 1
Is a single-tub type in which the washing tub 3 having a double structure is suspended from the housing 2 and supported, but the present invention is not limited to this.
For example, the washing machine may be a two-tub type having a washing tub and a dehydrating tub, and the washing tub may be fixed to the housing with a single tub having stirring blades at the bottom. And
The above-mentioned washing tub alone may be provided in the housing.

The washing tub 3 is not limited to the one supported in an inclined manner, but may be one in which the rotation center axis CL is arranged along the vertical line VL.

Further, the opening 21b may be provided not on the front surface of the outer frame 21 but on the rear surface thereof.

Further, it is more preferable that the inner diameter of the mounting hole 22d in at least one direction is smaller than the root diameter of the screw 80, but it is sufficient that the inner diameter is smaller than the outer diameter of the screw 80. Further, the shape of the hole may be a circular shape or an elliptical shape that is long horizontally.

Further, the convex portion 81 and the abutting member 82 may have any shape as long as they fulfill their functions.

In addition, various design changes can be made without changing the gist of the present invention.
