DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding lid mounted on a dehydration tub of a fully automatic washing machine.

[0002]

2. Description of the Related Art Currently used fully automatic washing machines include:
There are a type in which the side wall of the dewatering tub is cylindrical, and a type in which the upper part has a conical shape in which the upper part is widened. FIG. 8 shows a vertical sectional view of a fully automatic washing machine of a type in which the side wall of the dewatering tub is cylindrical. An opening / closing lid 3 which is opened / closed when putting on and taking out clothes is attached to an upper frame 2 constituting an upper part of the main body 1 via a pin 3a. A circuit unit 4 is provided.

[0003] A water tank 13 is elastically suspended and supported by a support member 14 in the main body 1. In the water tub 13, a dehydration tub 91 is rotatably supported around its central axis by being attached to the outside of a double shaft derived from the clutch mechanism 8 with a deceleration function. Is received via the belt 7 and the clutch mechanism 8. Many dehydration holes 1 are provided on the side wall of the dehydration tank 91.
9 are formed, and water contained in the clothes is drained out of the dehydration tub 91 through the dehydration holes 19 by centrifugal force at the time of dehydration. Further, a water tank cover 17 is provided on the inner side around the upper end opening of the water tank 13 so that clothing does not enter the gap between the water tank 13 and the dehydration tank 91.

A balancer 11 having a lint filter 10 is integrally mounted around the upper end opening of the dewatering tub 91.
The cover frame 12 which forms the circulation water channel 12 'for collect | recovering lint using this is provided. At the bottom of the dewatering tub 91, a pulsator 5 for stirring the clothes is rotatably supported by being attached to the inside of the multiple shaft led out from the clutch mechanism 8, and is similar to the dewatering tub 91 itself. The rotation of the drive motor 6 is transmitted and driven.

[0005] Below the balancer 11 in the dewatering tank 91,
A holding lid 161 for holding clothing so as not to protrude above the balancer 11 is attached. Since the holding lid 161 needs to be bent when it is attached to and detached from the dewatering tub 91, it is molded using a flexible material such as an EVA resin or a soft polyethylene resin. The conventional holding lid 161 already on the market is mounted on the dewatering tub 91 only when a washing mode dedicated to large clothing such as a blanket is selected. In this case, the pulsator 5 does not rotate alone and stirs the inside of the dewatering tub 91, but rotates integrally when the dewatering tub 91 rotates.

Here, a procedure for washing using the conventional holding lid 161 will be described. First, the opening / closing lid 3 is opened and large clothing is put into the dehydration tub 91 through the clothing input port 15. Next, the holding lid 161 is bent, and the dehydration tub 91 is moved from the clothing input port 15.
And press down the whole holding lid 161 strongly downward. Then, the user holds the ring portion 18 provided at the central portion of the holding lid 161 and gently pulls up the ring portion 18 until it comes into contact with the lower surface of the balancer 11.

At this time, the holding lid 161 is attached so that the lint collecting filter 10 is exposed thereon. Since the cover frame 12 forming the circulation channel 12 ′ for collecting the lint using the lint collection filter 10 swells inward from the side wall of the dewatering tank 91,
The holding cover 161 is attached with a portion corresponding to the cover frame body 12 curved.

FIG. 9 shows a top view of a conventional holding lid 161. As shown in FIG. The holding lid 161 has a circular disk shape on the outer periphery, and a ring 18 having a hole large enough to receive a wrist is provided at the center thereof.
A large number of small holes 20 for watering are formed on the entire surface so that water passes when water is supplied.

[0009] Although a fully automatic washing machine in which the side wall of the dewatering tub has a cylindrical shape and a holding lid used therein have been described above, a type in which the side wall of the dewatering tub has a conical shape in which the upper portion is widened at present. Fully automatic washing machines are also used. This does not provide a dehydration hole on the side wall of the dehydration tank,
At the time of dehydration, the water contained in the clothes rises along the side wall by centrifugal force and is discharged out of the upper end of the dehydration tub.During the washing and rinsing steps, the dehydration tub and the water tub surrounding it are dehydrated. Since water does not accumulate in between, it can save water.

[0010]

However, the holding lid 161 of the fully automatic washing machine according to the prior art shown in FIGS. 8 and 9 is used only when a washing mode exclusively for large clothes such as a blanket is selected. For example, when a user puts ordinary laundry including small clothing into the full capacity or more than the rated capacity and performs laundry in the ordinary laundry mode, the laundry in the dehydration tub 91 is popped out. Even if it is attempted to use the holding lid 161, small clothing jumps out of the ring portion 18 provided at the center of the holding lid 161, and is suddenly inserted into the gap between the water tank cover 17 and the balancer 11 to the dehydration tank 91. By applying the brake,
There is a possibility that an accident such as breakage or fall of the main body 1 may occur.

A cover lid 161 of a fully automatic washing machine according to the prior art has a simple circular outer periphery and a cover frame 1 formed so as to partially protrude inside the dewatering tub 91.
Since it is not fitted to the shape 2, a part of the dewatering tank 91 is mounted in a curved shape when it is mounted below the balancer 11. As a result, the fitting state between the dewatering tub 91 and the pressing lid 161 is incomplete, and the locking force is weakened, so that the pressing lid 161 may fall into the dewatering tub 91. In such a case, with the rotation of the dewatering tub 91, the holding lid 161 is entangled with the clothing, or a part thereof protrudes above the balancer 11 and comes into contact with the water tank cover 17 to hinder the rotation of the dewatering tub 91. There is a possibility that problems such as this may occur.

Further, since the holding lid 161 of the prior art fully automatic washing machine has a simple circular outer periphery, it is applicable to a fully automatic washing machine of a type in which the side wall of the dewatering tub has a conical shape in which the upper portion is widened. In this case, the water contained in the clothes at the time of dehydration rises on the side wall of the dehydration tub and drops into the water tub, thereby blocking the drainage portion provided in the balancer. Therefore, the holding lid 161 cannot be used in this type of fully automatic washing machine.

The present invention has been made to solve such a problem, and can be used for clothing of any size, for any washing mode, and falls into the spinning tub during rotation. A fully automatic washing machine that can be easily mounted firmly in accordance with the shape of the dehydration tub so that it can be used in a fully automatic washing machine of the conical shape with the side wall of the dehydration tub expanded at the top An object is to provide a holding lid.

[0014]

In order to achieve the above object, according to the present invention, a lower part of a balancer made of a flexible material and provided around a top opening of a dehydration tank of a fully automatic washing machine is provided. In a holding lid of a fully automatic washing machine having a substantially disc shape attached to a hole formed in the vicinity of the center thereof and having a size such that a few fingers can be inserted when attaching and detaching, and a large number of holes formed on the entire surface thereof A small hole for watering is provided.

Further, in the present invention, a cutout portion which fits into a frame forming a circulating water channel for collecting lint provided in a part of the dewatering tub is formed on the outer peripheral portion.

Further, according to the present invention, the balancer provided with the conical side wall whose upper part is widened and provided around the opening at the upper end thereof is provided with a dewatering tank provided with a drainage passage through which water is drained during dewatering. When used in a fully automatic washing machine, a notch is formed in the outer peripheral portion so as not to block the drainage path .

[0017]

Therefore, according to the present invention, since the hole used as a handle when attaching and detaching the holding lid is smaller than in the prior art, the laundry including small clothes is washed in the normal washing mode. Even so, small clothing does not jump out of the hole. Further, since a large number of small holes for watering are formed on the entire surface of the holding lid, water can be supplied to the dewatering tank even with the holding lid attached.

Further, according to the present invention, it is easy to mount the holding lid according to the shape of the dewatering tub, and the holding lid can be mounted on the dewatering tub without bending.
The fitting state is completed, the locking force is increased, and the holding lid does not fall into the dewatering tub.

Further, according to the present invention, even when used in a fully automatic washing machine of the type in which the side wall of the dewatering tub has a conical shape in which the upper part is widened, the notch portion is provided in the holding lid. Therefore, it is possible to prevent the drain path provided in the balancer from being blocked. In addition, since it is easy to mount the holding lid in accordance with the shape of the dewatering tub, it is easy to prevent the cutout portion from blocking the drainage path .

[0020]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a holding lid of a fully automatic washing machine to which the present invention is applied. FIG. 1 is a longitudinal sectional view of a fully automatic washing machine provided with a holding lid according to one embodiment of the present invention. This fully automatic washing machine is of a type in which the side wall of the dewatering tub 9 has a conical shape in which the upper portion is widened, and in FIG. 8, the side wall of the dewatering tub 91 used in the description of the prior art has a cylindrical shape. Unlike an automatic washing machine, a dehydration hole is not provided in the side wall of the dehydration tub 9. However, since the other components are the same, they are denoted by the same reference numerals, and description thereof will be omitted.

FIG. 2 is a top view of the holding lid 16 of the fully automatic washing machine according to the present embodiment. Two holes 16a, 16a are formed in the vicinity of the center of the holding lid 16, and serve as a handle when attaching / detaching the holding lid 16 to / from the dehydration tub 9. Since this hole 16a is only large enough to accommodate a few fingers, it is possible for a user to wash normal laundry including small clothing in the normal washing mode with the capacity being full or exceeding the rated capacity. Even in this case,
When the garment is mounted on the dewatering tub 9, the small clothing does not fly out during the rotation of the dewatering tub 9, and the operation can be safely performed. Of course, when large clothing such as a blanket is put into the dewatering tub 9 for washing, attaching the holding lid 16 can prevent the large clothing from floating and protruding above the balancer 11.

The holding lid 16 according to the present embodiment has a large number of small holes 20 for watering on the entire surface of the holding lid 16 so that water flows when water is supplied to the dewatering tub 9, similarly to the conventional holding lid 161. I have. However, unlike the conventional holding lid 161 having a simple circular outer circumference, the holding lid 1 according to the present embodiment is different from the holding lid 161 according to the present embodiment.
6, a notch 16c formed in a shape protruding inside the dewatering tub 9 so as to fit the cover frame 12 is formed.
And a plurality of notches 16b for not blocking the drain path (to be described later). In addition, holding lid 1
6 is formed by using a flexible material such as an EVA resin or a soft polyethylene resin as in the case of the conventional holding lid 161 because it needs to be bent when it is attached to and detached from the dewatering tub 9.

Here, a procedure for washing using the holding lid 16 according to the present embodiment will be described. First, the opening / closing lid 3 is opened, and clothes are put into the dehydration tub 9 through the clothes input port 15. Next, the holding lid 16 is inserted into the dehydration tub 9 from the clothing slot 15 while putting a finger on the hole 16a and bending the whole. At this time, when the amount of clothing is large and the holding lid 16 cannot be fully inserted below the balancer 11, the upper surface of the holding lid 16 is pressed downward, and the entire outer peripheral portion of the holding lid 16 reaches the lower side of the balancer 11. To enter.

Thereafter, it is pulled up gently with the hole 16a until it comes into contact with the balancer 11, and is held in the state shown in FIG. At this time, if the notch portion 16c and the cover frame body 12 bulging inward from the side wall of the dewatering tub 9 are fitted together, the positioning of the holding lid 16 in the circumferential direction of the dewatering tub 9 can be performed easily and reliably. Can be done.

Then, the operation is started in the normal washing mode. During the water supply, washing, and rinsing steps, as shown in FIG. 3, the clothes are uniformly distributed in the dewatering tub 9, and are not pressed above the balancer 11 by the pressing lid 16. In addition, at the time of the dehydration operation, as shown in FIG. 4, the clothes are pressed against the wall surface of the dehydration tub 9 by centrifugal force.
Again, the presser lid 16 reliably prevents the lifter 16 from rising above the balancer 11. When the entire process is completed, the holding lid 16 can be obtained simply by grasping the hole 16a and pulling it up.
Can be removed, and the washed clothes can be taken out from the clothes slot 15.

In this series of procedures, when the holding lid 16 is mounted on the dewatering tub 9, the cover frame 12 and the notch 16c are fitted to each other in order to perform positioning in the circumferential direction. FIG. 5 is a view of the section taken along line xx ′ of FIG. As described above, when the holding lid 16 according to the present embodiment is attached to the dewatering tub 9, the portion corresponding to the cover frame 12 does not bend unlike the related art, so that the holding lid 16 and the dewatering tub 9 are fitted. Since the engagement state becomes complete and the locking force increases, the holding lid 16 does not fall into the dewatering tub 9. In the figure, reference numeral 11a denotes a drainage path provided in the balancer 11, and 16b denotes a cutout formed in the outer periphery of the holding lid 16 so as not to block the drainage path.

Further, in a fully automatic washing machine in which the side wall of the dewatering tub 9 has a conical shape in which the upper part is widened, at the time of dewatering,
The water contained in the clothes rises on the side wall by centrifugal force and is discharged outward from the upper end of the side wall. FIG. 6 is an enlarged cross-sectional view showing a portion A of FIG. 1 and shows a state in which water that has risen on the side wall during dehydration passes through a portion of the balancer 11 provided around the upper end opening of the side wall. ing.

As shown in FIG. 6, during dewatering, water that has risen on the side wall of the dewatering tub 9 is discharged to the water tub 13 through a drainage path 11a provided below the balancer 11. In this case, since the holding lid 16 according to the present embodiment has the cutout portion 16b formed in the outer peripheral portion, water can pass under the holding lid 16 without stagnation.

FIG. 7 shows the drainage path 11a and the notch 1
FIG. 3 is a view of a cross section taken along line xx ′ of FIG. 1 viewed from below to show a positional relationship of FIG. As shown in FIG.
“a” is provided at equal intervals along the circumferential direction below the balancer 11. The notch 16b
Is formed so that when the positions of the holding lid 16 and the dewatering tub 9 are properly adjusted, two drainage paths 11a are included in the range.

As shown in FIGS. 2 and 5, the holding lid 16 has a notch 16
Since c is also provided, the positioning of the holding lid 16 and the dewatering tub 9 can be easily performed. Therefore, in FIG. 7, since the positions of the drainage path 11a and the notch 16b can be surely matched, the dehydration efficiency does not decrease even if the holding lid 16 is attached to the dehydration tank 9. Even if the holding lid 16 and the dewatering tub 9 are not properly aligned, at least every other drainage path 11a comes to the position of the notch 16b and is opened. Is possible.

The embodiment in which the holding lid of the fully automatic washing machine according to the present invention is applied to the fully automatic washing machine in which the side wall of the dewatering tub has a conical shape in which the upper portion is widened has been described.
The present invention is not limited to this. Of course, the present invention can be applied to a fully automatic washing machine in which the side wall of the dewatering tub has a cylindrical shape.

[0032]

The holding lid of the fully automatic washing machine according to the present invention is effective not only when the washing mode dedicated to large clothes is selected but also when the laundry including small clothes is washed in the normal washing mode. Also, since small clothing does not jump out of the hole used as a handle when attaching and detaching the holding lid, it can be used for clothing of all sizes and in all washing modes, and clothing jumps out of the dehydration tub Accidents can be eliminated. In addition, a number of small holes for watering are formed on the entire surface of the holding lid, and water can be supplied to the dehydrating tub even with the holding lid attached. It is not necessary to attach / detach the cover every time.

Further, according to the present invention, it is easy to mount the holding lid according to the shape of the dewatering tub, and furthermore, the fitting state is completed and the locking force becomes strong, so that the dewatering tub is provided. The lid does not fall into the inside. Therefore,
