BACKGROUND OF THE INVENTION The present invention relates to a device for washing, dehydrating, drying or simply drying suits, women's clothing, knit products and other general clothing, hotel linen, hospital standard bedding, etc. The present invention relates to a drum type processing device for laundry, which can be applied to machines, general household dryers and the like.

[0002]

2. Description of the Related Art In the laundry industry, used dirty towels, sheets, bandages and other laundry received from hotels and hospitals are processed and shipped as clean linen to hotels and hospitals. The processing steps include washing, dehydration,
Separately from drying and finishing, towels and other items that are completely dried are included in the process of ~, and sheets and bandages that require ironing are included in the process of ~ (however, the process is short). In the conventional machines, it is general that washing and dehydration are performed first, and then the laundry is transferred to another dryer for a drying process. Further, in a machine for continuously performing washing and dewatering, the outer circumference of the rotary drum is a perforated plate, and a plurality of so-called beaters for lifting the laundry are attached inside the rotary drum. Generally, the laundry is lifted upwards by the impact of falling and washed with detergent, chemical force such as temperature, etc. When the washing process is completed, this rotating drum is rotated at high speed and centrifugal force causes the laundry to wash. The water adhering to is shaken off and dehydrated. When the dehydration process is completed, the worker stops the washing and dehydrating machines, loads the laundry on a trolley or the like, and conveys it to the dryer.
After that, the laundry that has been washed and dehydrated is put into the drum of the rotary drum type dryer, and then the dryer dries the laundry by blowing hot air into the drum. In addition, some linens or sheets that need to be completely dried such as towels and semi-drying such as bandages move to the next ironing step.The drying time varies depending on the type of laundry, and the drying time is selected accordingly. Be done. The general prior art in which washing, dehydration, and drying are performed by separate machines has been described above. As a special example, so-called washing, dehydration, and dryer in which washing, dehydration, and drying are continuously performed by one machine. Is also commercially available.

A conventional washing technique will be described below with reference to FIG. 3 showing a conventional drum type processing apparatus for laundry.
Is a treatment tank, 2 is a drum, 3 is a beater for lifting laundry by rotation of the drum 2 (in the direction of arrow 6), and 4 is washing water supplied through a water supply valve 10 through a water supply pipe 11. Reference numeral 7 is a filter for removing thread waste, lint, etc. that are detached from the laundry 5, and is housed in a filter box 8 having a drain valve 9. Further, in this system, the liquid level of the wash water 4 is controlled by a liquid level gauge (not shown, such as a float type or a water pressure type), and when a specified amount flows in, the water supply valve 10
Is automatically closed. The drum 2 rotates from the start of water supply, and even after the liquid level of the wash water 4 reaches a specified value, the drum 2 rotates for a time determined by a timer, a circuit, or the like (not shown) to lift the laundry 5 with the beater 3. Is dropped and so-called tap washing is performed in the drum 2 to wash the laundry 5. After the washing is completed, the drain valve 9 is opened and the washing water 4 is discharged through the filter 7.

[0004]

As described above, the conventional drum-type washing method is a method of washing or drying by washing the laundry 5 with the beater 3 and dropping it naturally by gravity. Alternatively, during drying, the laundry 5 is continuously subjected to the dropping action, the stirring action, and the rubbing action from the drum 2. Drum 2 to laundry 5 as above
When the laundry 5 is an animal hair product representative of wool fibers, for example, a suit or a knit for women, the laundry 5 shrinks in the presence of water, as is widely known. This will result in a shrinkage accident. For this reason, animal hair products have conventionally been generally treated by so-called dry cleaning using an organic solvent as a washing liquid. However, due to the recent ozone depletion problem and groundwater pollution problem,
Freon 113 or perchloroethylene, which is a dry cleaning solvent that is currently widely used, is subject to very strict regulations, and thus it is desired to limit its use. SUMMARY OF THE INVENTION The present invention provides a drum type processing apparatus for laundry that does not shrink even when it is washed with water without using a dry cleaning solvent, and is intended to solve the conventional problems.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention is a drum type processing apparatus for laundry, in which laundry is washed, dehydrated, dried or washed with water for washing and dehydration. Alternatively, a water-permeable basket-like structure having a perforated wall surface such as a wire net is detachably attached, and the laundry is stored in the space formed by the inner wall of the drum and the outer wall of the basket-like structure and is washed or dried. The movement of the laundry due to the rotation of the drum is regulated, and this is a means for solving the problem.

[0006]

The present invention has been proposed for embodying a method of washing with water that does not cause shrinkage, and is necessary when laundry such as animal hair products may shrink during the washing or drying process. According to the structure, the drum has a perforated plate or a perforated wall surface such as a wire mesh so that a basket-like structure having water permeability can be mounted, and the space formed by the basket-like structure outer wall and the drum inner wall is formed. By holding the laundry and restricting the movement of the laundry during rotation of the drum, shrinkage of the laundry is prevented.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. FIG. 1 and FIG. 2 show an embodiment of the present invention. FIG. 1 is a front sectional view of a drum main portion, and FIG. .. In addition,
1 and 2, the same parts as those in FIG. 3 will be described with the same reference numerals. Now, the characteristic structure of the present invention is
The processing tank 1, a drum 2 having a beater for lifting the laundry 5 made of a perforated plate, and a basket-like structure 12 having a perforated wall such as a perforated plate or a wire mesh inserted in the drum 2 In this embodiment, the recess 12a that engages with the beater 3 is provided on the outer wall of the basket-shaped structure 12, the beater 3 is used as a kind of rail, and elasticity is easily utilized in the drum 2. It can be attached or detached. In addition, other configurations, that is, the filter 7,
Filter box 8, drain valve 9, water supply valve 10,
The water supply pipe 11 is exactly the same as the conventional technique shown in FIG.

The operation of the embodiment constructed as described above will now be described. First, after the basket-like structure 12 is inserted from the door 13 into the drum 2, the inner wall of the drum 2 and the outer wall of the basket-like structure 12 are inserted. The laundry 5 is stored in the space constituted by, and after the door 13 is closed, the drum 2 is rotated, for example, in the direction of arrow 6 by a motor and a control device (not shown). Next, the wash water 4 is supplied through the water supply valve 10 through the water supply pipe 11 until the liquid level reaches a specified value.
The laundry 5 proceeds while the movement of the laundry 5 is restricted. After the washing is finished, the drain valve 9 is opened to drain the washing water 4 through the filter 7. Further, when the drum 2 is rotated at a high speed when a dehydrating function is added, the laundry 5 is dehydrated by the centrifugal force and drained in the same manner as described above. Although the present embodiment has been described with respect to a drum type laundry processing device for business use, even in a domestic washing machine, by providing a basket-like structure having the same concept in the drum, exactly the same action and effect can be obtained. It goes without saying that you can expect it.

[0009]

As described above in detail, according to the present invention, when the laundry is an animal hair product and there is a risk of shrinking in ordinary laundry,
The movement of the laundry can be regulated by mounting the basket-like structure in the drum and storing the laundry in the space formed by the inner wall of the drum and the outer wall of the basket-like structure. Therefore, the laundry is prevented from being lifted by the beater and falling, and the shrinkage of the laundry can be prevented because it is not subjected to the stirring action or the rubbing action. If the laundry is made of a material such as hotel linen (cotton, cotton / polyester blend, polyester, etc.) that does not cause shrinkage, wash the basket-like structure without pre-installing it in the drum. The conventional washing is possible.
