Embodiment Construction

[0034] Such as figure 1 As shown, the fully automatic washing machine provided by the present invention includes a dehydration tank 2, a stirring blade 3, a dehydration shaft 5, a washing shaft 4, a brushless DC motor 7 and a clutch device. Wherein, the dehydration cylinder 2 is arranged in the outer cylinder 1 in a rotatable manner. The stirring blade 3 is installed in the dehydration vat 2 and can rotate independently of the dehydration vat 2 . Such as Figure 2a , Figure 2b As shown, the rotatable dehydration shaft 5 is supported by a bearing sleeve 20 and can transmit power to the dehydration cylinder 2 . The washing shaft 4 can transmit power to the stirring blade 3 . When the stator 7a of the brushless DC motor 7 is powered on, the rotor 7b will rotate accordingly. When switching between the washing mode or the dehydration mode, the clutch device can switch the transmission path of the brushless DC motor 7 to the washing shaft 4 or the dehydration shaft 5 . Clutch...

Abstract

The present invention relates to an initialization method of clutch motor in the automatic washing machine. Said method includes the following steps: stage for switching on power switch; stage for detecting switch of the clutch motor, if said switch is in switching-on state, starting the clutch motor and making the cam be rotated; at the same time starting time-counting stage; stage for judging that the clutch motor switch is in set time and can be converted into switching-off state or not; if it can be implemented in the set time, starding time-recounting stage; stage for judging that the driving time is reached to set time or not, if the driving time is reached to the set time, switching off the clutch motor, and retaining the cam in the initiating point. Said invented clutch motor can stably make drive switching between stirring blade and spindrier with short period of time.

Description

technical field [0001] The invention relates to a method for initializing a clutch motor in a fully automatic washing machine, in particular to a method for initializing a clutch motor in a fully automatic washing machine which can be washed with a stirring blade rotating at a low speed and dehydrated with a dehydration cylinder rotating at a high speed. Background technique [0002] Generally, a washing machine is a household appliance that uses the decontamination effect of detergent, the friction of water flow caused by the rotation of the stirring blades, and the impact of the stirring blades on water to wash daily necessities such as clothes. The washing machine first detects the amount and type of laundry through sensors, then automatically sets the washing mode, and performs washing under the control of a microcomputer after supplying water appropriately according to the amount and type of laundry. There are following two driving methods for traditional fully automati...
