Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a rotary washer-extractor for futons.

[Conventional technology]

A conventional washer-extractor for futons of this type has a cylindrical inner cylinder 20 as shown in FIG.
It is divided into two parts by a partition plate 21 that passes through the rotation axis, and a futon 23 is placed in a circle in each space 22, and the inner cylinder 20
There are devices that rotate and drive the water for cleaning and dehydration.

[Problem that the invention seeks to solve]

However, in such conventional examples,
A concave recess 22a is formed at the joint between the inner cylinder 20 and the partition plate 21, and as the inner cylinder 20 rotates, the futon 23 is slammed against the recess 22a, damaging the futon fabric. The problem is that the cotton may twist or separate, making it impossible to recycle it as a product.

Furthermore, since the washing liquid flows along the partition plate 21, the washing liquid is difficult to spray onto the futon 23, resulting in a problem that the efficiency of washing and rinsing is low.

Furthermore, since the amount of movement of the futon 23 in the space 22 is large, there is a problem in that the impact applied to the futon 23 is large and damages the futon fabric.

[Means for solving problems]

The washer-dehydrator for futons of the present invention has a structure comprising a sealable outer cylinder and an inner cylinder having a large number of small holes, which is rotatably driven within the outer cylinder to wash and dehydrate the futons. The inner cylinder is arranged with its axis horizontally, and a plurality of futon processing cylinders each having a circular cross section are arranged inside the inner cylinder so that their axes are parallel to the axis of the inner cylinder, so that adjacent futon processing cylinders can be processed. A space is formed between the outside of the cylinder and the inside of the inner cylinder, and a large number of cleaning liquid permeation holes are formed in the peripheral wall of the futon processing cylinder.

[Effect]

The futon placed in the futon processing cylinder rolls in the futon processing cylinder as the inner cylinder rotates and is beaten and washed. Further, since the inner surface of the futon processing tube is curved, the futon that falls as it rotates comes into uniform contact with the futon, thereby preventing damage to the futon.

The cleaning liquid permeation hole formed in the inner wall of the futon processing cylinder is designed to guide the cleaning liquid into the futon processing cylinder, the gap between the futon processing cylinders, and the futon processing cylinder in sequence as the inner cylinder rotates. The washing liquid is supplied from above the futon by dropping the washing liquid from above.

The washing liquid passes through a small hole formed in the inner wall of the inner cylinder, reaches the futon processing cylinder, and performs the action of rinsing the futon.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described in detail below.

In the figure, reference numeral 1 denotes an inner cylinder installed inside an outer cylinder (not shown) which has a sealable structure and into which a cleaning liquid is injected. It is rotated as follows.
Note that the rotation axis of the inner cylinder 1 is kept horizontal. Then, a large number of small holes 2 are opened in the inner wall of the inner cylinder 1,
The washing liquid can be freely flowed in and out. Further, this inner cylinder 1 is open only on one end surface, and
A plurality of futon processing tubes 3 are provided on the inner surface of the inner wall.

The futon processing cylinders 3 to 3 are arranged so that their axes are parallel to the rotation axis of the inner cylinder 1, and are adjacent to each other, and the futon processing cylinders 3, 3 and the inner cylinder are adjacent to each other. A gap 4 is formed between the holes 1 and 1.

Furthermore, the inner wall of the futon treatment cylinder 3 is provided with a large number of cleaning liquid passage holes 5, and the diameter of the holes 5 is 8.
mm and pitch are set to 23mm. The cleaning liquid can be moved to each space through the cleaning liquid permeation hole 5.

The inner cylinder 1 having such a structure is immersed in the cleaning liquid injected into the outer cylinder to the level shown by the dashed line in FIG. The futon 6 housed in the processing tube 3 is subjected to the following various actions.

First, the futon 6 in position (1) in Figure 2
Rinsing is performed by absorbing the cleaning liquid and moving to position (2). Next, at positions (3) and (4), the cleaning liquid is discharged. At this time, the futon 6 at position (2) receives the washing liquid discharged from the futon 6 at position (3) and rinses as it rises, and the washing liquid temporarily fills the gap 4a. Therefore, even if the futon 6 at the position (2) is raised, it is supplied with the washing liquid that falls from the gap 4a for a while.

Next, the futon 6 at position (5) is dropped and washed in the futon processing tube 3. At this time, since the inner surface of the futon processing cylinder 3 is a curved surface, the futon 6 will not be damaged and the cotton inside will not be twisted or cut.

In addition, when performing dehydration, the cleaning liquid in the outer cylinder may be drained and the inner cylinder 1 may be rotated at high speed.

Further, in the figure, reference numeral 7 denotes a donut-shaped lid provided on the opening edge of the inner cylinder 1, which prevents the futon 6 from flying out due to the rotation of the inner cylinder 1.

In addition, in the above-described embodiment, five futon processing tubes 3 are provided as shown in the drawings, but four
Even if the futon processing tubes 3 are provided in a range of 7 to 7, good results of washing efficiency are obtained.

In the embodiment described above, the futon processing tubes 3 are provided adjacent to each other, but they may be provided with a gap between them. Any configuration is sufficient as long as the cleaning liquid is temporarily stored in the gap.

Further, the rotation speed of the inner cylinder 1 is appropriately selected depending on the number and diameter of the futon processing cylinders 3 provided.

〔Effect of the invention〕

In this invention, by providing a futon disposal cylinder, the futon falls as the inner cylinder rotates, and the surface that is struck becomes a curved surface, eliminating the deviation of the load that occurs on the underside of the futon, and damaging the futon fabric, cotton, etc. It has the effect of preventing separation and twisting.

In addition, by providing multiple futon processing cylinders in the inner cylinder, the washing liquid that falls through the washing liquid permeation hole of the futon processing cylinder is prevented from immediately flowing into the futon processing cylinder below, and temporarily Washing water is stored in the gap between the futon disposal tubes, and the washing liquid drips from the top of the futon treatment tube below, so even if the futon rises above the level of the washing liquid, it will not be washed from the futon treatment tube above it. The liquid is supplied, which has the effect of making cleaning and rinsing better.

Furthermore, since the futon processing cylinder is cylindrical, it is easy to assemble to the inner cylinder, requiring no effort in manufacturing, and has the effect of reducing manufacturing costs.
