However, the conventional washing machine has the following disadvantages.

[0004] That is, for example, the stains of clothes are removed by washing because the washing liquid penetrates into the cloth of the clothes, so that the stains adhering to the fibers are separated from the fibers and include the separated stains. This is because the washing liquid leaks out of the clothes again. On the other hand, in the above-mentioned conventional washing machine, the rotation of the drum merely generates a vortex in the washing liquid, and cannot efficiently generate a water stream that allows the washing liquid to directly permeate the cloth of the clothes. Therefore, in the related art, the washing ability is low and the washing time has to be long in some cases. The longer the washing time, the more the clothes will be damaged.

[0005] Conventionally, when the washing liquid is stirred, the clothes rub against each other, and as a result, the fabric of the clothes is easily damaged or the clothes are entangled. Furthermore, in the past, for example, when a part of clothing is more dirty than other parts, it is not possible to wash that part more carefully than other parts, which also causes inconvenience. I was

Is lowered, and when the laundry object W is pressed downward,
The washing liquid contained in the laundry W is forcibly discharged to the outside of the laundry W. The mat 6 and the belt 31c have water permeability, and a part of the washing liquid is discharged below the mat 6 and the belt 31c, so that the washing liquid can be smoothly discharged from the inside of the washing object W to the outside. Be transformed into For this reason, the action of removing dirt from the laundry object W is excellent. As a result, according to the washing machine A, the washing time can be shortened, and the damage to the washing object W can be reduced correspondingly. Further, in the above-described push washing, since the cloths of the laundry object W do not rub against each other, the damage to the laundry object W is also reduced. Further, no entanglement occurs in the laundry object W.

The laundry W is intermittently fed by a predetermined pitch by the second conveyor 3B, and every time the laundry W is stopped, the washing is performed by the plurality of pressing members 21A. Therefore, the entirety of the laundry object W is appropriately washed by repeating the partial push washing of the laundry object W at various places. In particular, as described with reference to FIG. 6, the pressing members 21A of the first and third rows R1 and R3 and the pressing members 21A of the second and fourth rows R2 and R4 mutually move in a direction orthogonal to the transport direction. Because of the overlap, it is possible to prevent the unwashed portion from being generated on the laundry W in the same direction.

On the other hand, when washing the washing object W, only a suitable one of the plurality of pressing members 21A is selected and operated based on the information of the bar code 60, so that a part of the washing object W is partially It can be intensively pressed and washed. Therefore, the stain can be removed properly. During the stain removal, the other parts of the laundry object W are not washed unnecessarily, so that the damage to the laundry object W can be reduced. Since each pressing member 21A is elastically deformable, for example, it is possible to suppress the buttons and accessories attached to the laundry W from being crushed by the pressing members 21A. Furthermore, even when the thickness of the laundry object W is different for each part, the degree of elastic deformation of each pressing member 21A is different depending on the thickness,
There is also an effect that an appropriate pressing force can be applied to any of those portions. The mat 6 is also elastically deformable, and when the object to be washed W is pressed, the mat 6 is also deformed according to the pressing force and the shape and hardness of the object to be washed W. It will be excellent.

In parallel with the above-mentioned washing of the washing object W, bubble water of the washing liquid is jetted from the plurality of nozzles 23A to the washing object W. This bubble water is supplied to the washing tank 1A.
The washing liquid L1 in the inside is agitated to help prevent dirt washed off around the laundry object W. The bubbles contained in the bubbled water also exert an effect of performing what is called bubble cleaning for the laundry object W. In addition, when the bubble water is sprayed on the laundry W, the penetration of the washing liquid L1 into the fabric of the laundry W is also promoted. Therefore,
It is also suitable for washing an object to be washed which is difficult to penetrate the washing liquid, for example, made of water-repellent fibers.

After the above-mentioned washing process is completed, the mat 6 and the laundry object W are carried into the rinsing tub 1B by the third conveyor 3C and delivered to the fourth conveyor 3D. Also at this time, the barcode 60 and the end mark 62 of the mat 6 are detected by the barcode reader 76B and the end mark sensor 77A, and the plurality of pressing members 21B of the rinsing mechanism 2B move up and down and bubbles from the nozzle 23B. Water injection starts and ends at a predetermined appropriate time. Each pressing member 21B presses the laundry object W from above, as in the case of the above-described washing process. Therefore, the washing liquid contained in the cloth of the laundry W is forcibly discharged to the outside of the cloth, and the rinsing of the laundry W is efficiently performed. Also in the case of this rinsing, there is no possibility that the laundry W is damaged or entangled by rubbing. Also in this rinsing process, by selecting a part of the plurality of pressing members 21B, a part of the laundry object W can be rinsed more carefully than other parts. Since the rinsing water containing air bubbles is jetted from each nozzle 23B to the washing object W, the rinsing is also promoted by this.

After the rinsing is completed, the mat 6 and the object to be washed W are transferred to the winding device 4 by the fifth conveyor 3E.
Sent to In the winding device 4, as described with reference to FIGS. 8 and 9, the mat 6 and the laundry object W are wound around the winding drum 40 in a cylindrical shape. Since the take-up drum 40 has a one-stick shape, the belt 41 is moved by moving the roller 41a to a position indicated by reference numeral N1 in FIG.
If a gap is formed between the winding drum 2 and the winding drum 40, FIG.
As shown in FIG. 0, the mat 6 and the object to be washed W can be easily pulled out in the direction of the arrow N2 on one side of the winding drum 40 while keeping the cylindrical shape.

Thereafter, the laundry W is dehydrated using, for example, a drum type dehydrator (not shown). Preferably, the dehydrator is disposed near the winding device 4. When the laundry object W is loaded into the drum of the dehydrator, for example, the laundry object W is loaded together with the mat 6 in a tubular shape when the laundry object W is extracted from the winding drum 40.
This makes it easier to load the laundry W into the drum of the dehydrator, and also makes it easier to bring the laundry W along the peripheral wall of the drum. In operation of the dehydrator, the mat 6 may be extracted in advance from the drum of the dehydrator and only the laundry W may be dehydrated, or the laundry W and the mat 6 may be removed together without removing the mat 6. May be dehydrated.

After the dehydration process is completed, the laundry W is sent to the next step such as drying and ironing. For the mat 6, the sixth and seventh conveyors 3
F, 3G is used to return to the vicinity of the first conveyor 3A. This makes it convenient to use the mat 6 repeatedly. Both or one of the sixth and seventh conveyors 3F may place the dehydrated laundry object W on a mat 6.
It can also be used as a workbench for folding it up or exchanging the display pieces of the barcode 60.

FIG. 13 shows another example in which the washing machine A is used. In this usage example, the cover 8 is further placed on the washing object W when the washing object W is put into the washing machine A while being placed on the mat 6. The cover 8 has water absorbability and is elastically deformable, and is made of, for example, a plate-like sponge. The cover 8 is formed in a smaller size than the mat 6, for example, so that the bar code 60 and the end mark 62 of the mat 6 are not obscured.
A notch for exposing the 0 and the end mark 62 is formed. However, it is also possible to adopt a configuration in which the cover 8 is of the same size as the mat 6 and means corresponding to the barcode 60 and the end mark 62 is provided on the upper surface of the cover 8.

When the object W to be washed is put into the washing machine A in the above-described manner, for example, as shown in FIG. Is also pressed. Therefore, this cover 8
Is forced to permeate the laundry object W downward from above. Therefore,
Even when the thickness of the washing object W is small and the washing object W itself does not contain much washing liquid, the amount of the washing liquid that permeates the washing object W in the thickness direction can be increased. . Therefore, it is suitable for washing the thin laundry object W.

The specific configuration of each part of the washing liquid according to the present invention can be variously changed in design. Further, the specific configuration of each step of the method for using the washing machine according to the present invention can be variously changed.

For example, in the present invention, a brush 25 having a large number of bristles 25a as shown in FIG. 15 is used together with each of the pressing members 21A and 21B of the above-described embodiment, or as a pressing member in place of the pressing members 21A and 21B. It may be used as. Of course, the pressing member in the present invention is not limited to a rubber plate-shaped member or brush,
Other than these can be used. In addition, the size and number of the pressing members can be variously changed. For example, a plurality of pressing members may be provided in only one row in an appropriate direction, or the number of pressing members may be reduced to one.
As means for raising and lowering the pressing member, means other than the air cylinder may be employed.

As means for sequentially transporting the objects to be washed along a predetermined path, instead of using a plurality of conveyors,
Means using two conveyors can also be used. The object to be washed in the washing tub may be supported using equipment or members other than the belt conveyor, and the support means in the present invention is not limited to the belt of the conveyor. In the present invention, instead of the belt conveyor, for example, a chain conveyor may be used to convey the laundry object.
