BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described in detail.

The storage tank used in the present invention is not particularly limited as long as it is provided with a dialysis membrane. For example, as shown in FIGS. 1 and 2, a bag body 11 made of a dialysis membrane and the bag body 11 are built therein. An example is a car body 12.

The bag body 11 constituting the storage tank 10 is a dialysis membrane formed into a bag shape by an appropriate method.
The processing agent is loaded in the bag 11. Here, the dialysis membrane is a semipermeable membrane that can be fractionated according to the molecular weight, and has a large number of communicating pores of substantially the same shape in the membrane, and the molecules are separated by the difference in concentration on both sides of the membrane. What can be done.

Various types of dialysis membranes can be used. Examples of the dialysis membrane include those made of cellulose ester, regenerated cellulose and the like, and the appearance of which is sheet-like or tube-like (diameter of about 5 to 101 mm). can give. The shape of the communicating hole may be a symmetric type (having the same hole diameter from the inlet to the outlet of the communicating hole) or an asymmetric type (having different hole diameters from the inlet to the outlet of the communicating hole). . When a dry finishing agent is used as the treatment agent, it is preferable that the communication hole has a symmetrical shape.

Commercially available products of the above dialysis membrane include Spectrum CE dialysis tube, Spectrum RC dialysis tube,
Spectrum Biotech Dialysis Tubing (Medical Indu
stries. Inc.) and the like are known, and these can be used as the bag body 11. The dialysis membrane is appropriately selected depending on the treating agent, solvent and the like. For example, the dialysis membrane has a molecular weight cut-off (MWCO) of 100 to 10
There are about 100,000, but it is assumed that about 90% of the molecular weight of the treatment agent blocked by the film remains, and the molecular shape of the treatment agent, hydration property, electric charge, solvent properties, pH,
It is selected in consideration of ionic strength and the like.

As a method for forming the dialysis membrane thus selected into the bag body 11, any known method may be applied. For example, after gathering the edges of the sheet-shaped dialysis membrane in one place and then adhering the edges, etc., or the sheet-shaped dialysis membrane, resin sheet or rubber at both openings of the tubular dialysis membrane. Examples include a method of adhering and closing the sheet.

The car body 12 containing the bag body 11 is made of metal or plastic in the form of a car by an appropriate method, and a wall surface thereof is provided with a notch 13 for communicating the inside and outside. . More specifically, the car body 12 is a tubular body having both ends closed in a dome shape,
A strip-shaped notch 1 extending parallel to the axial direction on the peripheral wall surface.
3a is provided, and radial notches 13b are provided on the dome-shaped upper and lower end surfaces. This notch 13
Since a and 13b serve as passages for the solvent and the eluate from the bag 11, the elution amount can be controlled according to the opening area of the notch 13. In addition, the dome-shaped upper end surface is an opening / closing lid.

As the bag body 11, in addition to the one-chamber type shown in FIGS. 1 and 2, for example, a partition is provided inside the bag body with a sheet-like dialysis membrane, a resin sheet or a rubber sheet. One is divided into two or more rooms. For example, FIG. 3 is an example in which two partitions 14a and 14b are provided in a direction orthogonal to the axial direction of the bag body 11 to form three chambers, and FIG. 4 is one partition 14a in the axial direction of the bag body 11.
Is an example in which two rooms are provided.

Further, the bag body 11 may be composed of one bag or two or more bags. For example, FIG. 5 shows an example in which three bags 15a, 15b and 15c each having one chamber are bundled, and FIG. 6 shows an example in which two bags 15a and 15b each having two chambers are arranged in parallel. is there. Thus, by partitioning into two or more chambers or using a plurality of bags, when using two or more components, each component can be loaded separately according to the molecular weight, solvent, etc., as a result, There is an advantage that the amount of elution can be controlled more accurately, and that the storage stability of which is particularly poor in the mixed state can be used.

The car body 12 is not limited to the shape shown in FIGS. 1 and 2, but may be any shape as long as it can hold the bag body 11 inside. For example, a tubular body with both ends closed on a flat surface, a tubular body with only one end closed, or a tubular body with both ends open is given. Further, the shape is not limited to the cylindrical body, and may be a polygonal column body, a cone body, a polygonal cone body, or the like. However, if the bag 11 has a large opening, it is necessary to provide a stopper or the like so that the bag 11 does not fall out of the opening, or to install the bag 11 so that the opening does not face downward. The notch 13 formed in the car body 12 is not limited to the shape shown in FIGS. 1 and 2, and any shape may be formed in any part.

Further, the car body 12 has a shape other than the shape shown in FIGS. 1 and 2, for example, as shown in FIG.
The large-diameter tubular body 18 and the small-diameter tubular body 19 may be fitted together. According to this car body 12, the large-diameter tubular body 18 or the small-diameter tubular body 19 is rotated in the circumferential direction by an appropriate method to change the overlapping position of the tubular bodies 18 and 19 to form the cutout portion. The elution amount can be controlled by opening / closing the openings of 13c and 13d or changing the opening area.

The method of rotating is not particularly limited, and it can be performed not only manually but also by an electric method or the like. Further, there is no particular limitation on the timing of turning, and it may be performed at any time. Then, when the basket 12 shown in FIG. 7 is used and a dry finish is supplied in an automatic commercial dishwasher or a domestic dishwasher,
The above rotation can be performed as follows. That is, at the same time as the start of the rinsing step, at least one of the large-diameter tubular body 18 and the small-diameter tubular body 19 is electrically rotated to form the opening formed by the notches 13c and 13d, and the rinsing step is completed at the same time. This is performed by closing the opening formed by the notches 13c and 13d. As described above, it is not always necessary to rotate the rinsing process at the same time, and a timer or the like may be used to form the openings by the notches 13c and 13d after a predetermined time (several seconds to several minutes) has elapsed from the start of the rinsing process. Alternatively, the openings formed by the cutouts 13c and 13d may be closed before or after the rinsing process.

The shapes of the cutouts 13c and 13d are not limited to those shown in FIG. 7, and any shape may be used. The shapes of the cutout portions 13c and 13d of the large-diameter tubular body 18 and the small-diameter tubular body 19 may be the same or different from each other. For example, in FIG.
This is an example in which the notches 13c and 13d of both tubular bodies 18 and 19 are parallelograms of the same size, and FIG. 9 shows the shapes of the notches 13c and 13d of both tubular bodies 18 and 19. Are both squares of the same size. Further, FIG. 10 shows the cutout portions 13c of the tubular members 18 and 19,
The shapes of 13d are both triangular with the same size,
This is an example in which the directions of the apex angles of both triangles are arranged in the same direction, and FIG.
Is a triangular shape having the same size, and the apex angles of both triangles are arranged in opposite directions. Also,
7 to 11 show an example of a two-layered tubular body with both ends open, but the invention is not limited to this, and a two-layered tubular body with one end or both ends closed may be used. However, it may be a conical body having a double-layered structure with an open or closed bottom.

Further, the car body 12 does not necessarily need to have the notch 13 opened in advance.
The structure may be such that the opening is formed by a temperature change by using a shape memory alloy or a shape memory plastic. For example, as shown in FIG. 12, a state in which a car body 12 is formed of a shape memory alloy or a shape memory plastic, and a plurality of band-shaped bodies 12a are closed to cover a bag body 11 (not shown) at a predetermined temperature or lower. And at higher temperatures, each strip 12a opens outwards,
As shown in FIG. 13, the bag 11 may be exposed. With this structure, the release area can be changed by utilizing the temperature difference, and thereby the elution amount can be controlled.

Next, the treatment liquid supply method of the present invention will be described by taking the household dishwasher / dryer shown in FIG. 14 as an example. In the figure, 21 is a cleaning tank, a water supply pipe 22 communicates with the upper part of its side wall, and a water supply valve 23 is opened and closed,
Water is being introduced. Further, a dish basket 25 for storing an object to be washed 24 such as tableware is provided in the approximate center of the washing bath 21, and the storage bath 10 (dry finish) is provided inside the dish basket 25. The drug container for the drug is attached by the hook 33. 26
Is a cleaning nozzle having an injection hole 27 facing the object to be cleaned 24, and is capable of injecting a dry finish aqueous solution or the like transferred through a pipe 28 and a cleaning pump 29. In the figure, 30 is a heater for heating the wash water, and 31 is a filter for collecting the leftover food.

In the household dishwasher / drier having the above structure, a series of steps (washing step, rinsing step, drying step) including the supply of the treatment agent (dry finish) is performed as follows. First, the items to be cleaned 24 such as tableware are stored in the tableware basket 25, and the storage tank 10 is stored in the tableware basket 25.
Then, the dedicated cleaning agent is put into the cleaning tank 21, and the door of the dishwasher is closed. Then, after the water supply valve 23 is opened to supply water into the cleaning tank 21, the cleaning water heated by the heater 30 is transferred to the cleaning nozzle 26 by the cleaning pump 29 and is transferred to the object 24 to be cleaned in the dish basket 25. Jet it towards you. As a result, the object to be cleaned 24 is cleaned (cleaning step). Next, after draining the cleaning water, the water supply valve 23 is opened again to supply water into the cleaning tank 21. And
The supplied water is discharged by rinsing the bottom of the cleaning tank 21 without being sprayed from the cleaning nozzle 26.
Further, the water supply valve 23 is opened again to supply water into the cleaning tank 21. Then, the supplied water is transferred to the cleaning nozzle 26 by the cleaning pump 29, jetted, and rinsed for about 1 minute. After the jet rinsing for about 1 minute is repeated again, the water supply valve 23 is opened again to supply water into the cleaning tank 21, and then the water heated by the heater 30 is transferred to the cleaning nozzle 26 by the cleaning pump 29. Then, it sprays toward the tableware basket 25 and the storage tank 10 attached to it. As a result, the dry finish agent in the storage tank 10 is dissolved or diluted with water, and the dry finish agent aqueous solution passes through the communication holes of the dialysis membrane. The passed dry finishing agent aqueous solution is supplied to the article to be cleaned 24 in the tableware basket 25 to improve the finishing effect of the article to be cleaned 24. In this way, the cleaning target 24 is rinsed (rinsing step). Then, after a drying process, a series of operations of the household dishwasher / dryer are completed.

With the household dishwasher having the above-mentioned structure, it is possible to easily prepare and supply a treatment liquid having a predetermined concentration only by using the storage tank 10. Moreover, since the storage tank 10 is attached to the tableware basket 25 in the cleaning tank 21, an installation space for a processing agent storage tank, a pump for supplying the processing agent, etc. is not required, and space can be saved.
Further, even when the treatment agent is a liquid and insoluble matter such as a precipitate is generated during long-term storage, since the treatment agent hardly passes through the dialysis membrane, the treatment effect is not impaired. Furthermore, even if a treatment agent that is solid and difficult to maintain hardness is used, it is possible to supply a fixed amount by controlling the elution amount from the dialysis membrane, so the composition is very careful. There is nothing to pay attention to. In the case of the device having the above-mentioned configuration, once the bag 11 of the storage tank 10 is loaded with the treatment agent, storage, transportation, etc. may be carried out for each storage tank 10,
It has the advantage of being easy to manage. It is also advantageous from the viewpoint of hygiene management.

The present invention is not limited to the mode in which only one storage tank 10 is attached. For example, FIG.
As shown in FIG.
May be a mode in which two (not shown) are attached,
Alternatively, it may be a mode in which three or more storage tanks 10 are attached.

Also, as to the method of attaching the storage tank 10, as shown in FIGS. 14 and 15, the hook 33 is provided on the peripheral wall surface of the storage tank 10 and is attached to the tableware basket 25 by hooking it. However, it may be suspended by a string or the like. That is, the storage tank 10 is in the cleaning tank 21,
If it is a place where the washing nozzle 26 receives water spray,
It may be attached to any place in any way.

FIG. 16 shows an example of application to a household dishwasher / dryer in which the tableware basket 25 has two stages. Two storage tanks 10 each having a hook 33 on the peripheral wall are provided, and the tableware baskets above and below. The example attached to 25 is shown.
