Description
Technical Field
The invention relates to a clothes care machine, in particular to a clothes care machine control hanger shaking method.
Background
The function of the shaking clothes rack of the clothes nursing machine is mainly to shake off dust and thread wadding on clothes. At present, the way of shaking clothes is mainly divided into two types, one type is as in chinese patent CN200980156036.6, the clothes-drying rod in the clothes nursing machine is shaken, and the other type is as in korean patent KR1020120097669, the clothes-drying rod is rotated and twisted to shake the dust. Both of these two ways are not ideal, and the way of shaking the clothes-horse in the laundry care machine, the laundry is almost gently fluttered, and the dust on the laundry hardly falls off. The clothes hanger is rotated and twisted, so that the dust removing effect on two sides of clothes is good, but the dust removing method cannot be used for removing the dust on the clothes in the central area. The speed of the dither cannot be controlled by a closed loop.
The existing clothes are mainly shaken in the horizontal direction, so that dust on the clothes drops, and because the clothes are in a dry environment, the horizontal shaking mode can cause the friction of adjacent clothes to generate static electricity, and the static electricity has an adsorption effect on the dust, so that the dust can not well drop. Static electricity also causes adjacent clothes to stick.
In addition, the existing method for controlling the shaking clothes hanger is to transmit a bearing of a motor to a vertical connecting rod, and the vertical connecting rod drives the clothes hanger to shake up and down. Ideally, the dithering frequency can be stably output by controlling the voltage or current parameters of the motor through the front end, but the needed output torque of the motor is also unstable due to uncertainty of the weight of clothes on the dithering clothes rack. Such a method belongs to an open-loop control method, and it is impossible to achieve a constant output of the frequency even after the jitter frequency is changed by the load. And thus, is in need of further improvement.
