Problems solved by technology

[0019] In order to overcome the disadvantage of high noise in the existing washing machine, the present invention provides an anti-motor noise structure of a fully automatic washing machine, which can prevent the air flowing along the space between the permanent magnet of the rotor and the stator in advance when the motor is driven. The phenomenon that the air that stays in the slit gap of the stator collides with each other to produce a crackling sound and the resulting resonance sound

Embodiment Construction

[0056] Embodiments of the present invention will be described in detail below with reference to FIGS. 5 a to 11 of the accompanying drawings.

[0057] In the present invention, the stator 7 is fixed on the back of the water bucket 3, and the rotor 8 is directly connected to the drum shaft 17 connected to the drum 9 installed in the water bucket 3, so that when the stator 7 is powered on, the rotation of the rotor 8 In the direct-connected drum washing machine that rotates the drum 9 to achieve washing and dehydration, the outer surface of the stator 7 has a plug member that is inserted into the gap 13 between the slits 16 and fills the gap 13 between the slits. 40.

[0058]Here, the plug member 40 includes a socket portion 41 installed on the frame 70 of the stator 7 , in order to be able to correspond to the first connecting arched protrusion 71 for fixing the stator 7 on the rear wall of the bucket 3 . And the second connection arched protruding part 42 formed integrally wi...

Abstract

The invention discloses an arrangement for preventing the motor noise from full-automatic washing machine, including a motor stator mounted behind the water tank and the motor rotor connected with the rotary drum shaft in connection with the drum in the water tank, the plug components inserted into the gaps between each seams and filled the gaps are arranged on the external surface of the stator. the breaking sound and resonance resulted from the air fiction caused by the air flow between the air kept in the stator seam gap and the space between the magnet body along the rotor and the seam of the stator during the motor driving process are eliminated, thus the washing machine noise is reduced effectively.

Description

technical field [0001] The invention relates to a drum washing machine, in particular to an anti-noise structure of an electric motor. Background technique [0002] Generally speaking, the drum washing method is a method of washing by using the friction between the rotating drum driven by the motor and the laundry when detergent and washing water are put into the drum. There is no damage to the laundry, and the laundry will not be entangled with each other, and the washing effect of beating and rubbing can be obtained. [0003] An example of a conventional direct-connected drum washing machine will be briefly described below with reference to FIGS. 1 to 4 . [0004] Fig. 1 is a longitudinal sectional view of an example of the structure of an existing direct-connected drum washing machine, and Fig. 2 is an enlarged detailed view of part A of Fig. 1, and a bucket 3 capable of holding washing water is housed inside a casing 5, Above-mentioned bucket 3 is equipped with the dru...
