Problems solved by technology

[0011] Because there is an axial gap between the ball bearing inner ring 110a at the front of the support shaft 17 and the shaft 17, when the drum 9 rotates, the drum 9 and the shaft 17 will move within the size of the axial gap, which will cause the shaft 17 and The ball bearing inner ring 110a collides, causing friction noise

Embodiment Construction

[0027] The present invention is described in detail below with reference to accompanying drawing and embodiment:

[0028] Such as image 3 , 4 As shown, the technical solution of the present invention is: the stator 7 is fixed on the back of the outer cylinder 3, the rotor 8 is directly connected to the coupling shaft of the drum 9 arranged on the inner side of the outer cylinder 3, and when the stator 7 is powered on, the rotor 8 The rotation of the drum 9 drives the rotation of the drum 9, thereby realizing the functions of washing and dehydration, and in the directly connected drum washing machine with a gap between the ball bearing inner ring supporting the shaft 17 directly connected to the drum 9 and the shaft 17, the shaft 17 Between the inner ring 110a of the ball bearing 11a at the front and the front protrusion 170 of the shaft 17, a shaft with elastic force is provided along the direction of the rotation axis of the drum 9, which can reduce the vibration of the dru...

Abstract

The invention discloses an axial mobile noise preventing structure of barrel washing machine, which is characterized by the following: fixing stator on the back of outer cylinder; connecting rotor and cylinder in the outer case directly; remaining gap between ball bearing and axle to connect in the barrel washing machine directly; setting axial mobile elastic part of cylinder and axle to reduce the rotation of cylinder. The invention reduces noise due to air friction of cylinder and rotary axle along axial movement, which can be applied for barrel washing machine with certain incidence.

Description

technical field [0001] The invention belongs to a device for a drum washing machine, in particular to a noise preventing structure for axial movement of a drum washing machine capable of reducing noise generated by air friction caused by axial movement when the rotor of a brushless DC motor driving the drum washing machine rotates. Background technique [0002] Generally speaking, a drum washing machine is a device in which detergent, washing water, and laundry are put into a drum, and the drum is rotated by a driving force of a motor to wash the laundry. Such a drum washing machine has the advantages of minimizing the damage to the laundry, and the laundry is not easily entangled, and has the advantages of beating and rubbing. [0003] Such as figure 1 , 2 As shown, an outer cylinder 3 that can store washing water is provided inside the casing 5, and a drum 9 that can put laundry into it is provided inside the outer cylinder 3. A shaft 17 that can transmit the driving fo...
