Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and be not considered as limiting the invention.
Weighed below in conjunction with the accompanying drawings come fuzzy Weighing method, the fuzzy of washing machine of the washing machine for describing the embodiment of the present invention
Device and washing machine.
Fig. 1 is the flow chart of the fuzzy Weighing method of the washing machine according to the embodiment of the present invention.Wherein, implementation of the invention
Washing machine in example can be rotary drum washing machine, and the washing machine may include the clutch that motor and correspondence motor are set.
For example, clutch and motor can be installed on bottom plate, and keep certain spacing distance between the two, motor is passed
Driving wheel is arranged in the rotating shaft of motor, and driven by clutches wheel is set on the clutch, between motor drive and driven by clutches wheel
It is connected with being tensioned by driving belt, and Hall sensor is provided with clutch.
As shown in figure 1, the fuzzy Weighing method of the washing machine comprises the following steps：
