With continued reference to Fig. 5, further, agitator 40 is that upper surface is provided with radial protrusion 404 and circumferential recess 402
Disk-like structure, and mesh 406 is provided with agitator 40, therefore, in the rotation process of agitator 40, the water under agitator 40
The clothing that can be impacted in washing machine 001 upwards by mesh 406, strengthen the effect of the washing clothing of washing machine 001 with this.Separately
Outside, the radial protrusion 404 that the upper surface of agitator 40 is set can guide the water on agitator 40 to make circumferential flow, on agitator 40
The circumferential recess 402 that surface is set can guide the water on agitator 40 to make radial direction centrifugal flow.
In summary, decelerator 10 of the invention can make washing machine in washing shape by switching the position of clutch cover 128
Switch between state and dewatering state.When washing machine is in washing state, impeller 30 and agitator 40 can be according to default turns
Speed rotates than in opposite direction, improves the stirring capacity of washing machine.When washing machine is in dewatering state, interior bucket 20 is driven
It is dynamic.Therefore, decelerator 10 of the invention also makes impeller 30 and stirring on the premise of the original function of pulsator washing machine is ensured
Device 40 can rotate so as to make the water in washing machine form multiple vortex in opposite direction according to default rotating ratio
Shape current, the vortex shape current to the more preferable Ground shock waves of clothing in washing machine and beating, can improve the washing effect of washing machine
Fruit.
So far, combined preferred embodiment shown in the drawings describes technical scheme, still, this area
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these embodiments.Without departing from this
On the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to correlation technique feature, these
Technical scheme after changing or replacing it is fallen within protection scope of the present invention.
