Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for draining a solvent in a dry cleaning machine.

[Conventional technology]

In the dry cleaning operation, a cleaning process in which a solvent is supplied from a storage tank into the basket, and a dehydration process in which the washed solvent is discharged from the basket are repeatedly performed, and then drying and deodorizing processes are performed in sequence.

In recent years, there has been a strong desire to improve the efficiency of dry cleaning operations, but when trying to shorten the working time in the above work process, shortening the cleaning time directly reduces the cleaning power, and shortening the drying time also reduces the amount of solvent recovered. resulting in a decrease in

Among them, the length of time for supplying and draining the solvent to the basket does not affect the cleaning function. Therefore, in order to maintain the current cleaning function and shorten the working time, it is necessary to shorten the supply and drain time of the solvent. The important point is to shorten the time.

[Problem that the invention seeks to solve]

The conventional solvent draining method, as shown in Figure 2 (al to (C1),
While the basket 1 is being repeatedly rotated for cleaning, that is, forward and reverse, the pulp in a drain pipe 3 provided below the outer drum 2 is opened and drained. In this case, the solvent falls through the drain pipe 3 due to its own weight.

However, in the above liquid draining method, as shown in FIG.
Since the No. 8 agent is stirred up, the surface of the solvent is lowered, and the rate of discharge of the solvent falling under its own weight is reduced, resulting in a problem that it takes a long time to drain the liquid.

The object of the present invention is to solve the above-mentioned problems and provide a method for draining a solvent in a short time and efficiently.

[Means for solving problems]

In order to solve the above problems, the present invention drains the solvent with the basket stopped until the liquid level reaches the lower end of the basket, and then rotates the basket.

[Effect]

At the beginning of draining, the basket is stopped to prevent the liquid level from falling, and when the liquid level is lower than the bottom edge of the basket, the basket is rotated to prevent the solvent from being contained in the items to be washed. Sift off the solvent.

〔Example〕

Figure 1 shows the liquid drainage method of the present invention.
(As shown in bl, after the cleaning process is completed, Buskent 1 is stopped, and in that state, the valve of drain pipe 3 is opened to drain the solvent. In this case, the solvent is not scraped up by Buskent 1. Since the liquid level is maintained high, the falling speed of the solvent due to its own weight is maintained high, and the solvent is efficiently discharged.

As the liquid continues to drain, when the liquid level of the solvent drops below the lower end of the basket 1, as shown in Figure 1 (C1), the basket 1 is rotated forward and reverse to remove the inside of the items to be washed and the items to be washed. Sift off the solvent contained during washing and complete the drainage (first step
Figure cd)). The above operation can be carried out by providing a liquid level sensor on the outer drum 2 that is activated by a drain start signal, for example, and outputting a signal to drive the rotation of the basket 1 when the liquid level of the solvent passes the lower end of the basket 1. Set to .

〔Effect of the invention〕

As described above, this invention uses free solvent in the outer drum,
The system drains the liquid while maintaining a high liquid level, and then drains the solvent contained in the items to be washed, allowing efficient drainage and shortening the drain time. can.
