Embodiment 1
[0047] like figure 1 As shown, in this embodiment, the oil-water separator 1 of the dry cleaning machine is composed of a container with a certain volume. The top of the oil-water separation device 1 is provided with a liquid inlet, and the liquid inlet is connected to the drying air path through the condensation discharge pipe 2 . In this embodiment, the condensate discharge pipe 2 extends from the liquid inlet of the oil-water separation device into the oil-water separation device, and its extended end serves as the detection port 15 . The detection port 15 is provided with a photoelectric sensor 13 to detect the number of drops of oil-water mixture falling into the oil-water separation device 1 through the detection port 15 .
[0048] The photoelectric sensor 13 includes a transmitting end and a receiving end. The transmitting end and the receiving end are installed on the top of the oil-water separation device, and are arranged opposite to the detection port 15 axis. Th...
Embodiment 2
[0051] like figure 2 As shown, in this embodiment, a detection box 14 is provided in the middle of the condensate discharge pipe 2 of the dry cleaning machine, and the detection box 14 is composed of a box with a certain volume. There is a liquid outlet. The liquid inlet of the detection box is connected with the drying air duct through the upper part of the condensate discharge pipe, and the liquid outlet of the detection box is connected with the oil-water separation device through the lower part of the condensate discharge pipe. In this embodiment, the upper part of the condensate discharge pipe 2 extends into the detection box 14 from the liquid inlet at the top of the detection box 14 , and its extended end serves as the detection port 15 . The detection port 15 is provided with a photoelectric sensor 13 to detect the number of drops of the oil-water mixture flowing through the detection port 15 to obtain the number of drops of the oil-water mixture flowing into the oil...
Embodiment 3
[0055] like image 3 As shown, in this embodiment, the specific steps of the drying judgment method are as follows:
[0056] 1) After the dry cleaning machine is dried for a certain time T, the dry cleaning machine enters the drying stage, and starts to detect the number N of oil-water mixture droplets flowing into the oil-water separation device within each unit time t;
[0057] 2) Compare the number N of droplets detected in step 1) with the set value N'; when N>N', return to step 1), and the dry cleaner continues to dry;
[0058] When N≤N', the dry cleaner stops drying.
[0059] In this embodiment, the set value N' is calculated from the corresponding coefficient a of the material of the clothes washed by the dry washing machine and the weight m of the clothes to be washed.
[0060] The corresponding coefficient a of clothes of different materials is measured in advance through a large number of experiments, and the measured value is stored in the control circuit board of...
