Embodiment 1

[0046] In this embodiment, the concentration sensor 6 of the dry cleaning machine is composed of an electrochemical sensor. The electrochemical sensor includes: a detection probe and a control circuit.

[0047] After the evaporator condenses the steam of the dry cleaning solvent contained in the circulating air flow, the dry cleaning solvent that becomes liquid no longer flows with the circulating air flow. Therefore, it is necessary to install a concentration sensor at the front of the evaporator, so as to detect the concentration of the dry cleaning solvent vapor on the circulating air flow that has not been condensed.

[0048] Such as figure 1 As shown, the concentration sensor 6 is arranged in the drying air path 3 between the evaporator 10 and the exhaust port of the outer cylinder. The detection probe of the electrochemical sensor constituting the concentration sensor 6 is arranged on the inner wall of the drying air passage 3 between the evaporator 10 and the exhaust ...

Embodiment 2

[0050] Such as figure 2 Shown, in the present embodiment, concentration sensor 6 is by electrochemical sensor; The difference with embodiment one is: the detection probe of electrochemical sensor is arranged in the inner space of outer cylinder 1 near the outlet of outer cylinder, to measure outer cylinder 1 Concentration value P of dry cleaning solvent vapor in the gas. Preferably, the detection probe is arranged on the side wall of the outer cylinder 1 at the lower part of the exhaust port to avoid concentration detection of the gas at the air inlet of the outer cylinder, so as to improve detection accuracy and avoid misjudgment.

Embodiment 3

[0052] Such as image 3 As shown, in this embodiment, a method for judging drying of a dry cleaning machine, the specific steps are as follows:

[0053] 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 concentration value P of the dry cleaning solvent vapor contained in the airflow passing through the concentration sensor in the circulating air path;

[0054] 2) Compare the concentration value P detected in step 1) with the set value P'; when P>P', return to step 1), and the dry cleaning machine continues to dry; when P≤P', the dry cleaning machine stops drying .

[0055] In this embodiment, the set value P' is calculated from the corresponding coefficient a of the laundry material to be washed by the dry cleaning machine and the weight m of the laundry.

[0056] In this embodiment, the dry cleaning machine pre-stores the corresponding coefficient a of clothes of different materials int...

Abstract

The invention relates to a drying judgment method of a dry washer and the dry washer. The drying judgment method of the dry washer includes: when concentration of dry cleaning solvent steam in a circulation wind path reaches a set value during the drying process of the dry washer, judging that the drying process is finished, and then enabling the dry washer to stop drying. The dry washer comprises the circulation wind path formed by an outer barrel and a drying wind path which are communicated, wherein a drying module is arranged in the drying wind path, and a concentration sensor is arranged in the circulation wind path so as to detect the concentration p of the dry cleaning solvent steam contained in an air current which flows through the concentration sensor. The drying judgment method of the dry washer and the dry washer use the concentration sensor to detect the concentration of the dry cleaning solvent steam contained in the air current which flows through the concentration sensor so as to judge whether the drying is completed, and effectively improve detection accuracy during the drying process of the dry washer. The dry washer is simple in structure, convenient to operate, significant in effect, and suitable for promotion and application.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a dry cleaning machine, in particular to a drying judging method of the dry cleaning machine and the dry cleaning machine. Background technique [0002] Existing dry-cleaning machines that use dry-cleaning solvents to clean clothes include: dry-cleaning solvent tanks, dry-cleaning solvent pumps, washing drums, liquid storage tanks, fans, heaters, condensers, distillers, oil-water separators, vacuum pumps, and the like. The dry-cleaning process is roughly as follows: the dry-cleaning solvent in the dry-cleaning solvent box enters the washing drum through the pipeline through the pump to realize the liquid washing of the dry-cleaning solvent. Separation of solvents from clothing. When drying, the fan works, and the cold air is heated by the heat pump system to become hot air and enters the drum. The hot air takes the dry cleaning solvent vapor away through the liquid outlet and ent...
