Description

[Detailed description of the invention] This invention allows laundry containing moisture stored in an airtight box to
This invention relates to a wringer for a washing machine that depresses laundry by reducing the pressure in an airtight box with a vacuum device to inflate an airtight bag and press the laundry.

Conventional washing machine wringer has two parts that rotate in opposite directions.
The so-called roll method dehydrates the water-containing laundry by passing it between parallel rolls of books, and the other method involves storing the water-containing laundry in a perforated cylinder and centrifuging the water by rotating the cylinder at high speed. There is a centrifugal separation method.

However, the former roll method requires a considerable amount of effort as the rolls are rotated manually, and if there are protrusions such as buttons, they may get caught between the rollers and be torn to pieces. There is a drawback that it is difficult to narrow things down or that it cannot be narrowed down.

On the other hand, the centrifugal separation method does not require any labor as it is electric, but if the laundry is placed in a well-balanced cylinder and the rotation does not start, it tends to cause abnormal vibrations, which can lead to damage to the wringer. However, there are disadvantages in that wrinkles tend to remain on the laundry after spin-drying.

The present invention has been made with the aim of providing a wringer for a washing machine that eliminates all of the various drawbacks of these conventional devices.

The present invention will be explained in detail based on the following examples.

Reference numeral 1 denotes an airtight box, which consists of an airtight box body 2 and a lid 3.

First, the airtight box main body 2 is formed into a cylindrical body with an open top.The upper part is a space 2a for storing the laundry 5, and the lower part has a receiving plate 8 with a slight gap 7 between it and the push plate 18. of,
It is supported within the airtight box body 2 via a support frame 9.

The receiving plate 8 has a large number of small holes 10, 10, .

Further, a drain pipe 11 is connected through the bottom plate 6, and an on-off valve 12 is installed at its tip.

Reference numeral 13 denotes a suction pipe connected to a vacuum pump 4a, which will be described later, which passes through the bottom plate 6 in an airtight manner, extends upright to just below the receiving plate 8, bends its tip into an inverted U-shape, and connects the suction pipe to the opening of the suction pipe 13. Hole 1
4 is directed downward, so as not to inhale water that is dehydrated from the laundry 5 and falls through the small holes 10.

Further, reference numeral 15 denotes an air introduction pipe which is provided to penetrate airtightly through the airtight box main body 2, and is opened and closed by an on-off valve 16.

Next, the lid body 3 is a flat plate that is approximately equal to the outer diameter of the airtight box body 2, and has a smaller diameter than the airtight lid 17 that serves as the lid of the airtight box body 2, and the inner diameter of the airtight box body 2 for pressing the laundry 5. An expandable airtight bag 19, which almost reaches the receiving plate 8 when stretched like a bellows, is airtightly fixed between the pressing plate 18, which is a circular disc, and the airtight lid 17 and the pressing plate 18. Furthermore, a ventilation hole 20 is provided in the center of the airtight lid 17 to communicate the inside of the airtight bag 19 with the atmosphere.

21 is a guide ring wrapped around the outer periphery of the push plate 18;
Its outer surface is parallel to the inner surface of the peripheral wall of the airtight box main body 2, and the diameter is such that a slight gap is left at the peripheral edge.

The lid body 3 is attached with a backing 2 on the top surface of the opening of the airtight box body 2.
2 and place it airtightly.

Further, an airtight box support frame 23 is provided at the bottom of the airtight box 1,
A vacuum pump 4a is housed inside this airtight box support frame 23, and the above-mentioned suction pipe 13 is connected to the vacuum pump 4a.

Note that 24 is an exhaust pipe of a vacuum pump, and 25 is a vacuum gauge that indicates the airtight state of the airtight box 1.

Next, we will discuss the operation of the wringer of the washing machine of the present invention. First, the lid 3 of the airtight box 1 is removed, and the laundry 5 containing water to be wrung is placed in the space above the receiving plate 8 inside the airtight box body 2. 2a
and close the lid body 3 via the backing 22.

At this time, the lid 3 only needs to be placed on the airtight box body 2.

Next, the on-off valve 12 at the tip of the drain pipe 11 and the on-off valve 16 on the air introduction pipe 15 are closed, and the vacuum pump 4a is closed.
Activate.

Then, the air inside the airtight box 1 is sucked in through the intake hole 14 of the suction pipe 13 and exhausted to the outside through the exhaust pipe 24 of the vacuum pump 4a.

As the evacuation progresses, the pressure inside the airtight box 1 is gradually reduced, the degree of vacuum increases, and the lid 3 is sucked into the inside and compresses the backing 22, so that the lid 3 maintains airtightness without tightening the airtight box body 2. Can be retained.

As the pressure decreases, outside air is sucked into the airtight bag 19 through the vent hole 20, and the airtight bag 19 expands due to the pressure difference between the inside and outside. , it moves downward along the inner surface of the circumferential wall of the airtight box main body 2 while remaining almost horizontal without tilting like a piston of a pump, and presses the laundry 5 between the receiving plate 5 and the pushing plate 18. do.

Therefore, the moisture in the laundry 5 is squeezed out, and the small hole 10 provided in the receiving plate 8 and the inner wall of the airtight box body 2 and the receiving plate 8 are compressed.
It falls through the space between the two and accumulates on the bottom plate 6.

When the vacuum gauge 25 indicates that the pressure inside the airtight box 1 reaches the maximum degree of vacuum and stabilizes, the operation of the vacuum pump is stopped.

Next, when the on-off valve 16 of the air introduction pipe 15 is opened, the atmosphere is introduced into the airtight box 1 through the air introduction pipe 15, the pressure difference between the inside and outside of the airtight box 1 is eliminated, and the lid 3 can be opened easily.

At this time, the airtight bag 19 contracts due to the elasticity of the material.
The lid 3 can be easily removed.

The dehydrated water accumulated on the bottom plate 6 is discharged to the outside by opening the on-off valve 12 of the drain pipe 11.

In the above description, a vacuum pump 4a was used as the vacuum device 4, but a hydraulic sector 4b may be used instead of the vacuum pump, as shown in FIG.

When using this water ejector 4b, the suction pipe 13
It is not necessary to penetrate the bottom plate 6 and install the intake hole 14 in the bottom plate 6, and connect the water inlet of the water ejector 4b to the water pipe 2.
6 via an on-off valve 27, the water outlet is connected to a drain pipe, and the pressure inside the airtight box 1 is reduced by a water ejector.The other structure is the same as the vacuum pump described above. It is omitted because it has the same function and function.

In this case, the drain pipe 11 of the above embodiment can be omitted.

Further, in the above embodiment, the airtight box 1 is configured in a cylindrical shape, but it goes without saying that it may be configured in a rectangular tube.

Next, another embodiment of the present invention will be described based on FIG. 4.

In the embodiment shown in FIGS. 1 to 3, the airtight bag 19
is fixed to the airtight lid 17, but in the embodiment shown in FIG. The tip is opened in the bottom plate 6 to form a ventilation hole 20'.

When the pressure inside the airtight box 1 is reduced by the vacuum pump 4a, air flows into the airtight bag 19 through the ventilation hole 20', causing the airtight bag 19 to expand and push the push plate 18 upward, thereby closing the airtight lid 17 and the push plate 18. The laundry 5 is collected between the two and compressed and dehydrated.

In the embodiment shown in FIG. 4, it goes without saying that the airtight lid 17 does not require the ventilation hole 20.

The method of the present invention has a structural effect similar to that of the previous generation, so it uses atmospheric pressure to press the water-containing laundry very quietly, so it does not make any noise and is different from the conventional roll method. This is the most ideal squeezing method that squeezes the laundry without damaging the laundry or causing fine wrinkles like in the centrifugal separation method.

Furthermore, since there is no need to tighten the lid 3 to the airtight box body 2 each time during dehydration, the operation is easy and safe.

The squeezing force is extremely strong, reaching a maximum of 1kg/
cn! Therefore, a force corresponding to the area of the push plate can be exerted.

For example, if the area of the pressing plate is 500a+f, a maximum of 500ka can be applied, and if the area of the pressing plate is 700cJ, a maximum of 700kg can be applied, which is surprisingly large at first glance.

Therefore, by forming the volume of the airtight box to the required size, it is possible to easily dehydrate even so-called large laundry items such as blankets, curtains, and sheets used at home, making it extremely practical. It is a washing machine wringer.

Also, for those that use a water ejector as a vacuum device,
This has the effect of making the device smaller and cheaper.
