Description

[Detailed Description of the Invention] [Industrial Field of Application] This 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 attempts to solve]

However, in such conventional examples,
A concave recess 22a is formed at the joint between the cylinder 20 and the partition plate 21, and as the cylinder 20 rotates, the futon 23 is struck against the recess 22a, and the futon fabric is damaged. This method has the problem of twisting and separating the cotton, making it impossible to recycle it as a product.

In addition, since the washing liquid flows along the partition plate 21, the washing liquid is less likely to splash onto the futon 23.
The problem is that the rinsing efficiency 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]

This invention has a structure consisting of a sealable outer cylinder and an inner cylinder with many small holes that is rotated within the outer cylinder to wash and dehydrate the futon.
The internal space of the inner cylinder is divided into a plurality of futon processing spaces using partitions having a radial cross section centered on the rotation axis, and the partitions have a washing liquid permeation space provided therein, and Its structure includes a large number of small holes that communicate the futon processing space located on both sides and the washing liquid permeation space, and the surface near the inner cylinder is curved in a concave shape toward the facing futon processing space. It is said that

[Effect]

The futon placed in the futon processing space of the inner cylinder is
As the inner cylinder rotates, it rolls in the space and falls from one partition to the other, where it is beaten and washed. The curved edge of the partition closer to the inner cylinder makes uniform contact with the falling futon on its curved surface, thereby preventing the futon from being damaged.

As the inner cylinder rotates, the small holes opened in the partition body allow the cleaning liquid to pass through the futon processing space, the cleaning liquid permeation space, and the cleaning liquid permeation space.
By introducing the washing liquid into the futon processing space, the washing liquid is caused to fall through the small hole and is supplied to the futon from above the futon. For this reason, the cleaning liquid that adheres to the futon when passing through the cleaning liquid that has entered the lower part of the inner cylinder that is stored at the bottom of the outer cylinder will flow down from the futon that is raised from the washing liquid level. Since the washing liquid supplied from above is attached to the following futon, the time that the washing liquid is attached to the futon becomes long.

The cleaning liquid flows through small holes formed in the peripheral wall of the inner cylinder, and has the effect of rinsing the futon inside the inner cylinder.

〔Example〕

Hereinafter, details of this invention will be described with reference to an embodiment shown in the drawings.

In the figure, reference numeral 1 denotes an inner cylinder provided within an outer cylinder (not shown), and this inner cylinder 1 is rotationally driven around a rotation axis by a rotation drive device provided separately. A large number of small holes 18 are provided in the peripheral wall of the inner cylinder 1.
has been opened, and the washing liquid can be freely accessed. Further, the inner cylinder 1 is open only on one end surface, and its internal space is partitioned into six spaces by six partition plates 2 to 2 provided radially in cross section. A large number of small holes 3 are formed in the partition plate 2, and the diameter of the small holes is set to 8 mm, and the pit size is set to 23 mm. The cleaning liquid is allowed to move into each space through these small holes.

Further, the partition plates 2 to 2 constitute three pairs of partition bodies 19, two each, and a pair of partition plates 2,
The gap between the partitions 19 and 2 is a relatively narrow washing liquid permeation space 4, and the gap between these three partitions 19 is a futon processing space 5 in which the futon is washed or dehydrated.

Furthermore, the vicinity of the joint part of the partition plate 2 with the inner cylinder 1 is
The partition plate 2 is bent toward the facing futon processing space 5 side to form a curved portion 2a. This curved portion 2a is
The bottom surface of the futon 6 falling through each futon processing space 5 as the inner cylinder 1 rotates is evenly received, and the futon 6
to reduce the burden on the person, and as the futon 6 falls,
The futon 6 is slammed against the partition plate 2 to wash it.

Further, as shown in FIG. 2, the small hole 3 guides the cleaning liquid 7 flowing out from the futon 6 into the cleaning liquid permeation space 4 as the inner cylinder 1 rotates. The cleaning liquid 7 passes through the small hole 3 of the partition plate 2 located further below and drips onto the futon 6 located in the futon processing space 5 located below. For this reason, the futon 6 is supplied with washing liquid over the entire area by the washing liquid up to the level shown by the dashed line in the figure and the washing liquid 7 dripping, so that efficient washing is performed. In particular, as described above, by constructing the structure in which the washing liquid reaches the futon processing space 5 below through the two partition plates 2 through the washing liquid permeation space 4, the washing liquid 7 can be easily transferred to the futon processing space 5. It can be applied dropwise to

In addition, FIG. 3 explains the method of folding the futon 6 to be placed in the futon processing space 5. First, the futon 6 is folded lengthwise into three, and then both horizontal sides are folded inward. It is suitable for rotational movement within the space 5. Of course, it is also possible to fold the futon 6 in this way and put it in a net or the like for processing.

In the figure, reference numeral 8 denotes a donut-shaped lid provided at the opening of the inner cylinder 1 to prevent the futon 6 from flying out due to rotation of the inner cylinder 1.

The inner cylinder 1 having such a structure is installed in the above-mentioned sealable outer cylinder, and as shown in FIG. The lower part of the inner cylinder 1 is immersed in the cleaning liquid and soaks into the futon 6.

In the embodiment described above, the futon processing space 5
There are three futon processing spaces, but there are four to seven futon processing spaces5.
It is also possible to wash multiple futons at the same time. In this case, it goes without saying that the curvature of the curved portion 2a of the partition plate 2 should be selected appropriately so that it comes into even contact with the lower surface of the futon 6 at the position where the futon 6 falls. In particular, by setting the number of futon processing spaces 5 to an odd number, the weight of the inner tube 1 containing the futon is kept balanced.

It goes without saying that, in addition to the structure consisting of two partition plates, various structures having substantially a cleaning liquid permeation space can be applied to the partition body.

Further, the rotational speed of the inner cylinder 1 in the above embodiment is suitably 440 rotations per minute, but may be changed depending on the number of futon processing spaces 5.

Further, in the above embodiment, only the case of washing was described, but in the case of dehydration, the inner cylinder 1 is rotated at high speed to discharge water by centrifugal force.

[Effect of idea]

In this device, the horizontal inner cylinder is divided into three or more parts by partitions, so that while the futon made by one partition is moving upwards, it can be made by the next partition. The subsequent futons that are being raised begin to rise. Here, the washing liquid adhering to the upper futon flows down and is supplied to the lower futon through the small holes in the partition body and the washing liquid permeation space, so that the washing liquid adhering to the futon starts to rise and the washing liquid adhering to it flows down. Since the washing liquid is additionally supplied from above to the futon below which the liquid flows, the time for which the washing liquid adheres to the futon becomes longer and the cleaning effect becomes higher.

In particular, in this device, the cleaning liquid that passes through the partition and flows downward from the upper futon processing space to the lower futon processing space, once passes through the internal washing liquid permeation space when passing through the small holes in the partition. Even if there is a difference in the amount of washing liquid that passes through the small hole that contacts the futon and the small hole that does not touch the futon, the amount of washing liquid will decrease as it passes through the washing liquid permeation space and the small hole below. is averaged and supplied to the futon treatment space below, thereby making it possible to make the cleaning action uniform.

Furthermore, as mentioned above, since the inner cylinder is divided into three or more parts, when one of the partitions reaches above the rotating shaft, the partition on the front side of the rotation is still below the rotating shaft. It's not on. For this reason, the futon that is lifted by the partition on the post-rotation side of the futon processing space will fall onto the pre-rotation partition when the partition reaches the top of the rotation axis. It is washed by being beaten by the force of beating.

In this way, in this invention, the time for the cleaning solution to adhere to the futon is long, and the futon that has been lifted falls onto the partition on the front side of rotation and is washed by being beaten, making it difficult to wash the futon thoroughly. In addition, since the surface of the partition closer to the inner cylinder is curved in a concave manner, damage to the futon due to the washing by beating can be minimized.
