dry. The solvent gas evaporated from clothing 2 is transferred to air cooler 1.
7T: Condenses, enters the water separator 22 via the recovery path 21, and enters the clean tank 24 via the solvent pipe 23.

■When the drying is finished, the dampers 25 and 26 open as shown by the broken lines, and fresh air is taken in from the damper 25.
6 exhausts uncondensed solvent gas that cannot be recovered by the air cooler 17 to deodorize the solvent odor in the clothing 2.

The solvent 4 that entered the distiller 15 in the step of item 0.0 is evaporated, condensed and recovered in the condenser 27, passes through the water separator 22 and the solvent pipe 23, enters the clean tank 24, and is transferred to the overflow partition plate 28. Then return to solvent tank 3. In this case, the water separated by the water separator 22 is discharged to the outside of the system by the water distributor 29.

The above is an overview of the conventional dry cleaning process, and currently all dry cleaners that use these solvents process various types of aged clothing at the same time using large-capacity processing drums.

(Problems to be Solved by the Invention) Therefore, according to the conventional dryer one-leaning method, there are problems in that very lightly soiled clothing is contaminated by heavily soiled clothing, and that clothing belonging to an unspecified number of other people is contaminated. Since the cleaning process is performed at the same time, it is currently not possible to meet the demands of small-lot cleaning processes for individual consumers due to processing capacity, cost, etc.

The present invention aims to solve the problem that conventional dry cleaners are designed to wash a wide variety of clothes at the same time, and are unsuitable for washing in small loft units. The present invention also meets the recent latent needs of consumers, who do not want to wash clothes together with other people's clothes, and aims to provide a device that can perform individual dry cleaning in the true sense of the word. It is.

(Means for solving the problem) Therefore, the present invention has two or more independent treatment tanks,
In addition, the distiller, solvent tank, filter, and recovery air duct are shared, the cleaning solution is a cleaning solvent filtered by a filter, and each treatment tank can be operated and stopped independently. It is intended as a means to solve problems.

(Function) Since each treatment tank can be washed and dried independently by operating each valve, it is possible to run each treatment tank at random, and it is possible to perform cleaning and drying according to the degree of dirt, classification by clothing material, and individual It is possible to put small lots of clothing, such as, into each processing tank and start the operation at random. As a result, it is possible to sufficiently handle the cleaning of clothing in sections depending on the degree of soiling and the cleaning of small lots such as those for individuals.

(Example) The present invention will be described below with reference to the embodiments shown in the drawings. Fig. 1 shows an embodiment of the present invention, and the main difference from the conventional example (Fig. 2) is that it is possible to process clothing weighing approximately 2 to 3 kg. have the ability,
It has two or more processing tanks 103゜103a'-, and
07 to each processing tank 1'03.103a--, independently,
In addition, it has a button trap 113 with a float switch 119 that can be randomly fed and circulated through a filter 136 for cleaning.

Next, the drying recovery air duct 151 will be explained. As in the conventional case, it is provided with a lint filter 114, a fan 115, an air cooler 116, and an air heater 117, and the drying path can be switched by mivalve 1'24.
125, 202, 124a, 125a, and 202a, and if necessary, each treatment tank 103゜10
Dry air can be sent to 3a. A deodorizing device 200 can also be connected as an option.

Now, to explain the operation of the dry cleaning apparatus of the embodiment configured as above, first, the door 101
．． From 101a, clothing 102.102a of a small loft based on the degree of dirtiness, classification by clothing material, or individual unit is put in, the door 101.101a is closed, and operation is started. Each process proceeds in each processing tank 1o3° 103a, but since the processes are similar except for the time difference, only the processing tank 103 will be described below.

■ From the solvent tank 106 to the valve 129 and the pump 120
, the required amount of solvent 107 is pumped up into the processing tank 103 via the valve 128, filter 130, and valve 121.

(2) Slowly rotate the processing drum 104 and transfer the solvent 107 to the processing tank 103, valve 122, button trap 113, valve 127, pump 120, valve 128, filter 1.

16 and enters the water separator 110 via a recovery path 118. The solvent enters the ink 106 through the solvent pipe 111.

■If the deodorizing device 200 is attached, when drying is completed, the damper 201 opens as shown by the broken line, and the valve 202 opens.
A deodorizing fan (not shown) built into the deodorizing device 200 takes in fresh air from the damper 201 through a path consisting of Deodorize.

(2) The washed solvent that entered the distiller 10B in the step (2) above is heated, evaporated, condensed and recovered in the condenser 109, and enters the solvent tank 106 through the water separator 110 and solvent piping 111. In addition, the water separated by the water separator 110 is
It is discharged to the outside of the system through the water pipe 112. Incidentally, the float switch 119 of the button trap 113 serves to maintain the liquid level at a specified value G in order to maintain the process (2).

The above is the entire process of the dry cleaning apparatus of the present invention, and as mentioned above, each processing tank 103, 103a, - can be cleaned and dried independently by operating each valve. A feature of the present invention is that random operation of 1o3°103a- is possible.

For example, the processing tank 103 is connected to the clothing 102 through a path consisting of a valve 125, a recovery air duct 151, and a valve 124.
is being dried, and the processing tank 103a is drying the solvent tank 106.
The clothing 10 is made up of a valve 129, a pump 120, a valve 128, a filter 30, and a valve 121a.
The solvent 107 necessary for washing the clothes 102a is pumped up to wash the clothes 102a.
It seems like the machine is being cleaned. □If each of the processing tanks 103, 101a, etc. operates independently and randomly, the pump 120 and the fan 115 may operate constantly. Of course, each treatment tank.

It is also possible to simultaneously load the clothes 102 and 102a into the machines 103 and 103a and operate them at the same time. Further, the completion of all processes can be easily recognized by the operator using individual lamps, buzzers, etc. (not shown).

The embodiment shown in the drawings is a dry cleaning apparatus having two processing tanks for the sake of simplicity as shown in FIG. 1, but in order to make the most effective use of the present invention,
It is optimal to have 4 to 6 treatment tanks. Furthermore, in the above embodiment, an example was introduced in which the deodorizing device 200 was attached.
Of course, the solvent recovery rate can be improved by attaching a solvent recovery device, which is commonly used at present. Furthermore, in the example shown in Fig. 1, an example of a nonflammable solvent that can be used continuously from cleaning to drying was explained, but the same concept can be applied to so-called petroleum-based dry cleaners that use mineral turpentine. It goes without saying that it can be done.

(Effects of the Invention) The present invention is configured as explained above in detail, and since each treatment tank can be operated independently, it is possible to sufficiently respond to cleaning requests in small lots such as individual units. can.
