Problems solved by technology

[0007] However, the humidity sensor and temperature sensor used in the above schemes all have poor accuracy and are prone to wear and tear.
This makes the dry cleaning machine using the above-mentioned device and method prone to the situation that the judgment of the end of drying is not timely and the failure rate of the dry cleaning machine is high.

Embodiment 1

[0049] Such as Figure 4 As shown, in this embodiment, the fast imager 6 includes: a light emitting diode 61, emitting light to the coordinate positioning plate; an optical filter 62, filtering the emitted light reflected from the coordinate positioning plate; an optical sensor 63, filtering Fast imaging of light, converting the received filtered light into electrical signals; and image analysis chip 64, analyzing and processing the continuous images generated by the light sensor, and obtaining the moving displacement of the fast imager from the electrical signals.

[0050] The fast imager 6 is arranged horizontally, and one end thereof is a transmitting end 60 . One side of the launch end 60 is provided with a coordinate positioning plate 12, and the coordinate positioning plate 12 is vertically arranged to cover the moving path of the fast imager, so as to reflect the light emitted from the launch end by the fast imager moving with the outer cylinder , and transmit the refl...

Embodiment 2

[0058] In this embodiment, the fast imager 6 is arranged horizontally between the outer cylinder 2 and the casing 1 ; preferably, the fast imager 6 is arranged above the outer cylinder 2 and below the top plate of the casing 1 .

[0059] Such as figure 2 As shown, in this embodiment, a spring 13 is connected to the middle of the horizontal fast imager 6, and the spring 13 extends upward to connect with the top plate of the casing 1, and extends downward to connect with the top of the outer cylinder 2; Preferably, the spring 13 is on the same plane as the axis of the outer cylinder 2 . Therefore, after the outer cylinder 2 moves with the load variation, the fast imager 6 generates a vertical displacement L under the pulling force of the spring 13 . By detecting the displacement L of the fast imager 6, the displacement of the outer cylinder 2 of the dry-cleaning machine can be characterized, and thus the load m of the dry-cleaning machine can be characterized, and the indirect...

Embodiment 3

[0063] Such as image 3 As shown, in this embodiment, an installation box 14 protrudes downward from the top plate of the housing 1 of the dry cleaning machine, and the fast imager 6 is disposed in the installation box 14 . The fast imager 6 is connected to the top plate of the casing 1 via a spring 13 , and the spring 13 extends downward through a through hole provided on the bottom plate of the installation box 14 and is connected to the top of the outer cylinder 2 . The side plate of the installation box 14 close to the emitting end 60 of the fast imager constitutes the coordinate positioning plate 12 . Therefore, it is realized that the fast imager moving with the outer cylinder is installed in an independent installation box, and the loss caused by the moving collision of the fast imager during transportation is avoided.

Abstract

The invention relates to a household dry cleaning machine and a control method in the field of washing machines. The dry cleaning machine comprises a shell (1), an outer drum (2), an inner drum (3) and a drying system; the outer drum (2) is arranged in the shell (1) through at least one telescopic shock absorber; a quick imager (6) moving along with the outer drum (2) is arranged on the outer drum (2), a coordinate positioning plate (12) for reflecting emissive rays of the quick imager (6) is arranged on the shell (1), and the quick imager (6) receives reflected rays to obtain a displacement L. When the dry cleaning machine works, whether liquid feeding and / or drying is finished is judged according to the displacement L of the quick imager moving along with the outer drum. The dry cleaning machine is simple in structure, convenient to operate and significant in effect, and therefore is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a dry cleaning machine, especially a household dry cleaning machine and a control method. 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 air channel. After the ho...
