Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Prior Art Currently used fully automatic washing machines include
There are a type in which the side wall of the dehydration tank has a cylindrical shape and a type in which the upper part has a conical shape with a widened upper part. FIG. 8 shows a vertical cross-sectional view of a fully automatic washing machine of the type in which the side wall of the dehydration tub is cylindrical. An opening / closing lid 3 that is opened / closed at the time of putting in and taking out clothes is attached to an upper frame body 2 constituting an upper part of the main body 1 through a pin 3a, and a control panel is provided below a front operation panel 2 '. A circuit unit 4 is provided.

Inside the main body 1, a water tank 13 is elastically suspended and supported by a support member 14. In addition, a dehydration tank 91 is attached to the outside of the multiple shaft derived from the clutch mechanism 8 with a speed reduction function in the water tank 13 so that the dehydration tank 91 is rotatably supported around the central axis thereof. Is driven via the belt 7 and the clutch mechanism 8. A large number of dehydration holes 1 are provided on the side wall of the dehydration tank 91.
9 is formed, and the water contained in the clothes is discharged to the outside of the dehydration tank 91 through the dehydration hole 19 by the centrifugal force during the dehydration. Further, a water tank cover 17 is provided inside the periphery of the upper end opening of the water tank 13 so as to prevent clothes from entering the gap between the water tank 13 and the dehydration tank 91.

A balancer 11 having a thread waste filter 10 is integrally attached around the upper end opening of the dehydration tank 91, and the thread waste filter 10 is provided in a part of the dehydration tank 91.
A cover frame body 12 is provided which forms a circulating water channel 12 'for collecting yarn waste. A pulsator 5 for stirring clothes is rotatably supported at the bottom of the dehydration tub 91 by being attached to the inner side of the multi-spindle derived from the clutch mechanism 8, like the dehydration tub 91 itself. The rotation of the drive motor 6 is transmitted and driven.

Below the balancer 11 in the dehydration tank 91,
A pressing lid 161 for pressing the clothing so as not to protrude above the balancer 11 is attached. Since the pressing lid 161 needs to be bent when it is attached to and detached from the dehydration tank 91, it is molded using a flexible material such as EVA resin or soft polyethylene resin. The conventional pressing lid 161 which is already on the market is attached to the dehydration tub 91 only when the washing mode for large clothes such as a blanket is selected. In that case, the pulsator 5 does not rotate independently to agitate the inside of the dehydration tank 91, but integrally rotates when the dehydration tank 91 rotates.

Here, the procedure of washing using the conventional pressing lid 161 will be described. First, the opening / closing lid 3 is opened and large clothes are put into the dehydration tank 91 through the clothes insertion port 15. Next, the pressing lid 161 is bent to allow the dehydration tub 91 to pass through the clothes inlet 15.
Put it inside and press down the entire pressing lid 161 strongly. Then, holding the ring portion 18 provided in the central portion of the pressing lid 161, lightly pull it up until it comes into contact with the lower surface of the balancer 11.

At this time, the pressing lid 161 is attached so that the thread waste collecting filter 10 is exposed. Since the cover frame body 12 forming the circulating water channel 12 ′ for collecting the lint using the lint collection filter 10 bulges inward from the side wall of the dehydration tank 91,
The pressing lid 161 is attached such that the portion that contacts the cover frame 12 is curved.

FIG. 9 shows a top view of a conventional pressing lid 161. The holding lid 161 has a disk shape with a circular outer periphery, and a ring portion 18 having a hole large enough for a wrist to enter is provided in the center portion thereof.
A large number of small holes 20 for sprinkling are formed on the entire surface so that water can pass through when water is supplied to the.

Up to this point, the fully-automatic washing machine of the type in which the side wall of the dehydration tub is cylindrical and the pressing lid used therefor have been described, but at present, the side wall of the dehydration tub is of a conical shape with an expanded upper part. Fully automatic washing machines are also used. This does not have 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 due to the centrifugal force and is discharged from the upper end of the dehydration tank.When washing and rinsing, the water in the dehydration tank and the water tank surrounding it are removed. Since water does not collect in the meantime, it can save water.

[0010]

However, the pressing lid 161 of the conventional automatic washing machine shown in FIGS. 8 and 9 should be used only when the washing mode for large clothes such as blankets is selected. Therefore, for example, when the user carries out normal laundry including small clothes in the normal washing mode by filling the laundry with the full capacity or exceeding the rated capacity, the laundry in the dehydration tub 91 pops out. Even if the pressing lid 161 is used so as not to prevent the small clothes from popping out of the ring portion 18 provided in the central portion of the pressing lid 161, the small clothes are caught in the gap between the water tank cover 17 and the balancer 11 and suddenly placed in the dehydration tank 91. By applying the brake,
There was a possibility that an accident such as breakage or fall of the main body 1 occurred.

Further, the cover 161 of the fully automatic washing machine according to the prior art has a simple circular outer periphery and is formed so as to partially project inside the dehydration tub 91.
Since the shape does not fit in 2, it is attached to the lower side of the balancer 11 in the dehydration tank 91, and a part thereof is attached in a curved shape. As a result, the fitting state between the dehydration tub 91 and the pressing lid 161 becomes incomplete and the locking force becomes weak, so that the pressing lid 161 may fall into the dehydrating tub 91. In such a case, with the rotation of the dehydration tub 91, the pressing lid 161 is entangled with the clothes, or a part thereof protrudes above the balancer 11 and comes into contact with the water tub cover 17 to hinder the rotation of the dehydration tub 91. There was a possibility that problems such as

Further, since the pressing lid 161 of the conventional fully automatic washing machine has a simple circular outer periphery, it is applied to a fully automatic washing machine of the type in which the side wall of the dehydrating tub has a conical shape with its upper portion widened. If this is attempted, the water contained in the clothes will rise up the side wall of the dehydration tub during dewatering and will escape to the water tub, blocking the water draining part provided in the balancer. Therefore, the pressing 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 clothes of any size and any washing mode, and falls into the spinning tank while it is rotating. It is easy to install it firmly according to the shape of the dehydration tank so that it can be used even in a fully automatic washing machine of the type that has a conical shape with the side wall of the dehydration tank widened. It is intended to provide a holding lid.

[0014]

In order to achieve the above object, in the present invention, a lower side of a balancer made of a flexible material and provided around an upper end opening of a dehydration tub of a fully automatic washing machine. In a pressing lid of a fully automatic washing machine having a substantially disc shape that is attached to a hole, a hole is formed in the vicinity of its central portion and has a size for inserting a few fingers when attaching and detaching, and a large number of holes formed on the entire surface. It has a small hole for watering.

Further, according to the present invention, a cutout portion which fits into a frame body which forms a circulating water channel for collecting lint provided in a part of the dehydration tank is formed in the outer peripheral portion.

Further, according to the present invention, the dewatering tank is provided with a conical side wall having a widened upper portion, and a balancer provided around the upper end opening thereof is provided with a draining portion for draining water during dewatering. When used in a fully automatic washing machine, a cutout portion is formed in the outer peripheral portion so as not to block the water draining portion.

[0017]

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

Further, according to the present invention, the pressing lid can be easily attached in conformity with the shape of the dehydration tank, and the pressing lid can be attached to the dehydration tank without bending.
The fitting state becomes perfect and the locking force becomes strong, and the pressing lid does not drop into the dehydration tank.

Further, according to the present invention, when used in a fully automatic washing machine of the type in which the side wall of the dehydration tub is a conical shape with its upper part widened, the holding lid is also provided with a notch. Therefore, it is possible to prevent the drainage portion provided in the balancer from being blocked. Moreover, since it is easy to attach the pressing lid in conformity with the shape of the dehydration tank, it is easy to prevent the cutout portion from blocking the drainage portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a pressing lid of a fully automatic washing machine to which the present invention is applied will be described below with reference to the drawings. FIG. 1 is a vertical sectional view of a fully automatic washing machine equipped with a pressing lid according to an embodiment of the present invention. This fully automatic washing machine is of a type in which the side wall of the dehydration tub 9 has a conical shape with an expanded upper part, and the side wall of the dehydration tub 91 used in the description of the prior art in FIG. 8 is of a cylindrical type. Unlike the automatic washing machine, the side wall of the dehydration tub 9 is not provided with a dehydration hole. However, since the other components are the same, the same reference numerals are given and the description thereof is omitted.

FIG. 2 is a top view of the pressing lid 16 of the fully automatic washing machine according to this embodiment. Two holes 16a, 16a are formed in the vicinity of the central portion of the pressing lid 16, and serve as a handle when the pressing lid 16 is attached to and detached from the dehydration tub 9. Since the hole 16a is only large enough to accommodate a few fingers, the user may wash the normal laundry including small clothes to the full capacity or to exceed the rated capacity to wash in the normal washing mode. Even if this holding lid 16
If the is attached to the dehydration tub 9, small clothes do not jump out while the dehydration tub 9 is rotating, and can be operated safely. Needless to say, when a large clothes such as a blanket is put in the dehydration tub 9 for washing, by attaching the pressing lid 16, it is possible to prevent the large clothes from floating and protruding above the balancer 11.

Further, the holding lid 16 according to the present embodiment has a large number of small holes 20 for sprinkling formed on the entire surface thereof so that water can pass through when the water is supplied to the dehydration tub 9, like the conventional holding lid 161. There is. However, unlike the conventional pressing lid 161 having a simple circular outer periphery, the pressing lid 1 according to the present embodiment is different.
The outer peripheral portion of 6 has a cutout portion 16c shaped to fit the cover frame body 12 formed so as to partially project inside the dehydration tank 9.
And a plurality of notches 16b for not blocking the drainage path (described later). The cover 1
Since 6 needs to be bent when it is attached to and detached from the dehydration tub 9, it is molded using a flexible material such as EVA resin or soft polyethylene resin, like the conventional pressing lid 161.

Now, the procedure for washing using the pressing lid 16 according to this embodiment will be described. First, the opening / closing lid 3 is opened, and clothes are put into the dehydration tank 9 through the clothes insertion port 15. Next, the pressing lid 16 is inserted into the dehydration tub 9 through the clothes insertion port 15 while bending the whole by placing a finger on the hole 16a. At this time, when the amount of clothes is large and the pressing lid 16 cannot fit under the balancer 11, the upper surface of the pressing lid 16 is pressed downward so that the entire outer peripheral portion of the pressing lid 16 reaches the lower side of the balancer 11. I will enter.

After that, the hole 16a is held and lightly pulled up until it comes into contact with the balancer 11, and the state shown in FIG. 1 is maintained. At this time, if the cover frame 12 bulging inward from the side wall of the dehydration tub 9 and the notch 16c are fitted together, the pressing lid 16 can be easily and reliably positioned in the circumferential direction of the dehydration tub 9.

During the water supply, washing, and rinsing steps, as shown in FIG. 3, the clothes are evenly distributed in the dehydration tub 9 and are not pressed above the balancer 11 by being pressed by the pressing lid 16. Further, during the dehydration operation, as shown in FIG. 4, the clothes are pressed against the wall surface of the dehydration tank 9 by centrifugal force.
Again, the pressing lid 16 ensures that the balancer 11 is prevented from rising upward. When the whole process is completed, just hold the hole 16a and pull it up
Can be removed, and the washed clothes can be taken out from the clothes insertion port 15.

In this series of procedures, when the pressing lid 16 is attached to the dehydration tub 9, the cover frame 12 and the cutout portion 16c are fitted to each other in order to perform circumferential positioning. FIG. 5 is a view of the xx ′ cross section of FIG. 1 seen from below to show the mounting state. As described above, when the pressing lid 16 according to the present embodiment is attached to the dehydration tank 9, the portion that abuts the cover frame 12 is not curved unlike the prior art, so that the pressing lid 16 and the dehydration tank 9 are fitted together. Since the combined state is complete and the locking force becomes large, the pressing lid 16 does not drop into the dehydration tub 9. In the figure, reference numeral 11a is a drainage passage provided in the balancer 11, and 16b is a cutout portion formed on the outer peripheral portion of the pressing lid 16 so as not to block it.

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

As shown in FIG. 6, at the time of dehydration, the water that has climbed up the side wall of the dehydration tank 9 is discharged to the water tank 13 through the water 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 being stagnant.

FIG. 7 shows the drainage path 11a and the cutout portion 1.
It is the figure which looked at the xx 'cross section of Drawing 1 from the lower part in order to show the physical relationship of 6b. As shown in FIG.
The a's are provided below the balancer 11 at equal intervals along the circumferential direction. Also, the cutout portion 16b
Is formed so that two drainage paths 11a are accommodated within the range when the pressing lid 16 and the dehydration tank 9 are properly aligned.

As shown in FIGS. 2 and 5, the pressing lid 16 has a notch 16 having a shape that fits the cover frame 12.
Since c is also provided, the pressing lid 16 and the dehydration tub 9 can be easily positioned. Therefore, in FIG. 7, the positions of the drainage path 11a and the cutout portion 16b can be surely aligned with each other, so that the dehydration efficiency does not decrease even if the pressing lid 16 is attached to the dehydration tank 9. Even if the positions of the holding lid 16 and the dehydration tub 9 are not properly aligned, at least every other drainage path 11a comes to the position of the notch 16b and is opened. Therefore, the dehydration operation should be performed. Is possible.
