Embodiment 1

[0054] In this embodiment, the set value Pb is stored in the dry cleaning machine, which is compared with the detection value P to determine whether the drying of the dry cleaning machine is over; and the safety value Pa is compared with the detection value P to determine The value of whether the door of the dry cleaner can be opened. Said set value Pb>safety value Pa.

[0055] like figure 1 As shown, the specific working process of the dry cleaning machine is as follows:

[0056] 1) The dry cleaning machine starts to work. After performing the washing and drying procedures in sequence, it starts to enter the drying procedure, and uses the concentration sensor to detect the concentration value of the dry cleaning solvent vapor in the circulating air path composed of the drying air path and the outer cylinder, and obtains the detection value. value P;

[0057] 2) Compare the detection value P with the preset value Pb in the dry cleaning machine: when P>Pb, the dry cleaning m...

Embodiment 2

[0064] The difference between this embodiment and the first embodiment is that: the set value Pb=safety value Pa.

[0065] like figure 2 As shown, the specific working process of the dry cleaning machine is as follows:

[0066] 1) The dry cleaning machine starts to work. After performing the washing and drying procedures in sequence, it starts to enter the drying procedure, and uses the concentration sensor to detect the concentration value of the dry cleaning solvent vapor in the circulating air path composed of the drying air path and the outer cylinder, and obtains the detection value. value P;

[0067] 2) Compare the detection value P with the preset value Pb in the dry cleaning machine: when P>Pb, the dry cleaning machine continues to dry, and perform step 3); when P≤Pb, the dry cleaning machine stops drying, Execute step 4);

[0068] 3) After a certain period of time t, the concentration sensor detects the concentration value of the dry cleaning solvent vapor again t...

Embodiment 3

[0071] The difference between this embodiment and Embodiment 1 is that the dry cleaning machine is provided with a pre-judgment time T0-T1. When the dry cleaning machine satisfies the following two conditions at the same time: the drying time T is between the predicted time T0 ~ T1, and the detection value of the dry cleaning solvent vapor concentration P ≤ the set value Pb, the dry cleaning machine will finish drying.

[0072] like image 3 As shown, the specific working process of the dry cleaning machine is as follows:

[0073] 1) The dry cleaning machine starts to work. After performing the washing and drying procedures in sequence, it starts to enter the drying procedure, time the drying time T, and use the concentration sensor to detect the concentration in the circulating air path composed of the drying air path and the outer cylinder The concentration value of dry-cleaning solvent vapor obtains the detection value P;

[0074] 2) Compare the detection value P with the...

Abstract

The invention relates to a control method of a dry cleaning machine and a dry cleaning machine. The control method comprises steps of during the work of the dry cleaning machine, detecting concentration of dry cleaning solvent steam in a washing drum and/or a drying air path, locking a machine door when the detection value is larger than a safety value, and opening the machine door when the detection value is smaller than the safety value. The dry cleaning machine comprises a circulating air path formed by the washing drum and the drying air path communicated with the washing drum. A drying assembly is disposed in the drying air path; and a concentration sensor is disposed in the circulating air path to detect concentration value (P) of dry cleaning solvent steam contained in the air flow flowing through the concentration sensor in the circulating air path. The washing machine door can be opened and closed via detection of concentration of dry cleaning solvent air in the washing drum so as to prevent leakage of the dry clean solvent and guarantee user safety; dry cleaning machine safety can be improved; and possibility of wrong operation of the user can be lowered. The dry cleaning machine is simply structured and convenient to operate, has obvious effect and can be 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, especially a method for controlling 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 enters the ...
