As shown in FIG. 2, the dry cleaning machine has a basket 2 installed inside the washing tub 1 that accommodates the laundry and rotates forward and backward, and a button trap 4, which carries the solvent supplied from the base tank 3 into the washing tub 1. Cleaning is carried out by circulating the solvent through the solvent circulation circuit A which passes through the pump 5 and the basket 2. After this washing step is completed, the solvent is removed from the washing tub 1, and then the washing tub 1 is dried while recovering the solvent contained inside the washing tub 1.

This is done by circulating the air through the heater 8 and the gas circulation circuit B of the basket 2. That is, the air heated by the heater 8 contacts and dries the items to be washed in the basket 2, while gasifying the solvent contained in the items to be washed. After the air containing the solvent gas collects lint and the like in the lint filter 9, it is sucked into the fan 6 and sent to the cooler 7. In the cooler 7, the solvent gas is liquefied by the cooling and condensation action and air is The liquefied solvent is separated from water in a water separator 10 and then collected in a clean tank 11.

収のみとなる（乾燥工程後期）。 On the other hand, the air from which the solvent gas has been removed is heated to the heater 8.
The water is reheated and sent into the washing tub 1. This circulation continues until the inside of the washing tub 1 reaches a predetermined drying temperature (the first half of the drying process). After reaching the drying temperature, the heater 8 shuts off the steam and only the solvent is recovered by the cooler 7 (the second half of the drying process). ).

By the way, in the above drying process, when the drying state of the clothes is measured over time, in the first half of the drying process,
The amount of solvent recovered per hour increases rapidly, but in the latter stages of the drying process when the concentration of solvent contained in the clothes decreases, the amount recovered per hour decreases dramatically. The work of drying clothes on the street cannot be completed.

燥に比べて乾燥工程前期における時間当りの溶剤
回収量の上昇も早く、また、乾燥工程後期の溶剤
濃度が低い状態でも時間当りの回収量が増加し、
乾燥時間が大きく短縮される効果がある。 As a solution to this problem, a device has been proposed that reduces the pressure inside the washing tub 1 to dry the washing tub. In other words, this method aims to reduce the vaporization and condensation temperature of the solvent by reducing the pressure inside the washing tub 1, thereby increasing the recovery efficiency of the solvent.Drying by this reduced pressure drying is faster than drying without reducing the pressure. The amount of solvent recovered per hour in the first half of the drying process increases quickly, and the amount recovered per hour increases even when the solvent concentration is low in the latter half of the drying process.
This has the effect of greatly shortening drying time.

高級になり、装置自身も大きなものとなるため、
全体として高価なものになるという問題がある。 However, in the above-mentioned vacuum drying method, in order to reduce the pressure inside the washing tub, the gas (air and solvent vapor) in the washing tub is usually sucked in with a vacuum pump, etc., the solvent is recovered from the sucked gas, and, You have to save it. For this reason, the specifications of the vacuum pump become high-grade, and the equipment itself becomes large.
There is a problem in that the overall cost is high.

In order to solve the above problems, this invention

The interior of the washing tub exhibits a pressure higher than normal pressure due to the supply of solvent during the washing process, and when the drying process begins, the internal pressure increases due to the partial pressure of the evaporated solvent gas. Therefore, when the gate valve is opened during or before the drying process, air containing solvent gas in the washing tub flows into the air bag via the solvent recovery device due to the pressure difference. When air is stored in the air bag and the air in the washing tub becomes diluted, close the gate valve and perform drying in this state. As the solvent is recovered, the pressure inside the washing tub will be reduced. do.

FIG. 1 shows an example of implementing the invention. As shown in the figure, a solvent recovery cooler 13 is connected to the washing tub 1 via a gate valve 12.
3, an inflatable air bag 14 and a water separator 15 are connected. The water separator 15 is provided with a solvent recovery pipe 16 that communicates with the solvent tank 11 .

アバツグ１４を膨張させる。 In the dry cleaning machine of the embodiment configured as described above, the gate valve 12 is opened to communicate the washing tub 1 and the air bag 14 during the drying process or between the end of the washing process and the drying process. In this case, before the gate valve 12 is opened, the pressure inside the washing tub 1 is normally 1.2 to 1.3 Kg, depending on the solvent vapor pressure, etc.
f/cm 2 is greater than atmospheric pressure (1Kg/cm 2 ), and when the gate valve 12 is opened, air containing solvent gas in the washing tub 1 flows into the air bag 14 and inflates the air bag 14. .

後、タンク１１に戻される。 The gate valve 12 is opened for a required period of time, and when the pressure inside the washing tub 1 becomes equal to or lower than atmospheric pressure, the gate valve 12 is closed. During this operation, the air containing the solvent gas passes through the solvent recovery cooler 13 to recover the solvent gas, and only the air is guided to the air bag 14. On the other hand, the solvent liquefied in the cooler 13 is sent to the water separator 15 and separated from water, and then returned to the tank 11.

できる。 With the gate valve 12 closed, the air inside the washing tub 1 is in a dilute state, and as the drying process progresses to the latter stage, the pressure gradually decreases due to a decrease in the solvent vapor pressure due to the recovery of the solvent. It has been confirmed that the degree of pressure reduction is such that when the laundry in the basket 2 is completely dry, the pressure in the washing tub 1 is reduced to 0.7 to 0.8 Kg・f/ cm2 . There is. In this way, the pressure reduction progresses as the solvent vapor concentration decreases, so the drying rate is always maintained at a high level, making it possible to significantly shorten the drying process.

As explained above, in this invention, the pressure inside the washing tub can be reduced by a simple structure in which a solvent recovery device and an air bag are connected to the washing tub. It can be produced at a much lower cost.
