Figure 1 shows the circuit structure of a dry cleaning machine. Cleaning in such a dry cleaning machine involves pumping solvent from base tank 2 into basket 1.
The cleaning process is carried out in such a way that the basket 1 is rotated forward and backward to mix the solvent and soap with the items to be washed inside, thereby removing dirt from the items to be washed.

When cleaning is completed, the dirty solvent is drained into the distiller 3, where it is indirectly heated by a steam heat source. Due to this heating, the solvent boils at 121°C at normal pressure (atmospheric pressure) in the distiller 3, and the evaporated solvent vapor enters the condenser 5 via the standpipe 4, where it is liquefied and then passed through the water separator. In step 6, the solvent and water are separated by specific gravity and collected in the base tank 2.

When the solvent boils down in the distiller 3 in this way,
The solvent becomes foamy and grows toward the top of the distiller 3, and as boiling continues, the foam of the solvent flows into the condenser 5.
The solvent penetrates into the water separator 6 and base tank 2, and the soap, dirt, water, etc. contained in the froth mix into the solvent. When cleaning is performed by circulating the solvent mixed with soap, dirt, etc. into basket 1 in this way,
This has negative effects such as shrinking the laundry and making the laundry discolored or stained.

However, since there is a lot of soap and dirt inside the distiller 3 along with the solvent, the detection structure using a phototube mistakenly detects the soap and dirt attached to the inner wall of the distiller 3. This has the disadvantage that detection may become unstable.
