Method for controlling clutch of single-tube washing machine

Abstract

To provide a motor that does not use a pulse motor to make the rotation speed of the clutch switch to an ultra-low speed, even when the gap between the meshing parts of the clutch is reduced, it can still be connected reliably, and can prevent a large impact sound when switching to achieve A clutch control method for a quiet single-tub washing machine. The dehydration shaft is connected with the washing shaft through a clutch device. The structure of the clutch device is that the clutch pin arranged on the plunger can be freely connected and disengaged combined with the clutch plate fixed on the washing shaft as the drive shaft of the motor, wherein The plunger can be attracted or repelled by the electromagnetic coil fixed on the dehydration shaft to switch between the washing mode and the dehydration mode. In the clutch control method of the single-cylinder fully automatic washing machine, when switching the washing mode and the dehydration mode, the aforementioned motor After starting, turn off the power supply, and when the rotation speed of the drive shaft is decelerated to a predetermined value by the subsequent inertial rotation, the electromagnetic coil is energized to connect the clutch pin to the clutch disc.

Description

technical field [0001] The invention relates to a clutch control method of a single-cylinder fully automatic washing machine. Background technique [0002] Existing single-cylinder fully automatic washing machines such as image 3 Shown, well-known in outer case 20, be provided with water tank 21 freely swingingly, in this water tank 21, be provided with washing and dewatering tank 18 freely, at the bottom of this washing and dewatering tank 18, rotary vane 3 is provided. [0003] And, the drive shaft as the washing shaft that is connected on the rotary blade 3 is connected with the motor 1 by a deceleration mechanism, and the dehydration shaft that is connected to the washing and dehydration tank 18 is connected with the drive shaft through a clutch device 8, and only when washing and rinsing The rotary blade 3 rotates at a low speed, so that a vortex occurs in the washing and dehydrating tank 18 for washing and rinsing. Moisture content of the laundry in 18 is scattered b...

Problems solved by technology

[0013] When the gap in the rotation direction of the engagement portion of the fitting protrusion 13 and the engagement recess 15 is large, the shock noise during the torque variation due to the vibration of the rotation direction of the clutch engagement portion is also increased, which cannot meet the requirements of recent years. mute request

[0014] In order to eliminate the aforementioned problems, the shaking of the rotation direction of the meshing part can be reduced, but if so, in the current method of controlling the low speed of the motor through a switch or phase control, the speed increases, and the jumping phenomenon that the meshing part is not meshed will occur. There is a possibility of damage to the engaging part

In addition, if a pulse motor is used in the motor, it can rotate at an ultra-low speed, but it will increase the cost
