Embodiment 1

[0061] Such as figure 2 As shown, in this embodiment, the damping rod 5 is composed of a fixed rod 51 and a telescopic rod 52, and the fixed rod 51 is provided with a hollow chamber for telescopic movement of the telescopic rod. The first end of the fixed rod 51 is mounted on the outer cylinder 3 via a hinge, and the first end of the telescopic rod 52 is mounted on the casing 1 via a hinge; the second end of the fixed rod 51 is provided with a hollow The cavity communicates with the opening for the second end of the telescopic rod 52 to be installed in the hollow cavity. Preferably, a damping member (not shown in the drawings) is provided at the opening of the second end of the fixed rod to provide buffering and damping force for the telescopic rod.

[0062] The second end of the fixed rod 51 extends toward the direction of the telescopic rod 52 and is provided with a mount 53 for installing the photoelectric sensor 6 . The photoelectric sensor 6 includes a transmitting end...

Embodiment 2

[0066] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that: the second end of the fixed rod 51 extends toward the direction of the telescopic rod 52 to provide a first mounting seat 54 and a second mounting seat 55 for the photoelectric sensor 6 to install. The above-mentioned first mounting base 54 and second mounting base 55 are symmetrically arranged relative to the telescopic rod 52 . One end of the first mounting seat 54 and the second mounting seat 55 are respectively connected to the fixed rod 51 , and the other ends extend in the air along the axis of the telescopic rod 52 . The photoelectric sensor 6 includes a transmitting end 61 and a receiving end 62 , the transmitting end 61 and the receiving end 62 are arranged facing each other, and are respectively installed at the suspended ends of the first mounting base 54 and the second mounting base 55 . A scale plate 56 matched with the transmitting end 61 and the receiving end 62 i...

Embodiment 3

[0070] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the fixed rod 51 and the telescopic rod 52 are respectively provided with a first mounting seat 54 and a second mounting seat 55, and the first mounting seat 54 and the second mounting seat 55 The transmitting end 61 and the receiving end 62 of the photoelectric sensor 6 are respectively installed on it, and the transmitting end 61 and the receiving end 62 are arranged facing each other.

[0071] The transmitting end continuously sends out detection gratings to the receiving end. After the relative displacement between the telescopic rod and the fixed rod, the distance between the transmitting end and the receiving end changes, and the transmission time of the detection grating received by the receiving end changes, the control circuit of the photoelectric sensor generates a signal to the control circuit board of the dryer, and the control The circuit board analyzes and processe...

Abstract

The invention relates to a household dry washer and a control method thereof, and belongs to the clothes washer field. The household dry washer comprises a housing, an outer barrel, an inner barrel and a drying system, wherein the bottom of the outer barrel is installed in the housing through at least one damping piece which can elastically expand and contract along the axial direction, and a sensor is arranged on each damping piece so as to detect changes of an expansion amount of each damping piece, and thereby obtains changes of the load weight of the outer barrel of the household dry washer so as to judge whether drying is completed. The household dry washer judges whether liquid feeding and the drying are completed according to the changes of the load weight of the outer barrel during the liquid feeding and drying process. The household dry washer is simple in structure, convenient to use, remarkable 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, 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...
