Ventilation and dust filtering device for motor of washing machine

Abstract

The invention discloses a ventilation and dust filtration device for a motor of a washing machine. The ventilation and dust filtration device comprises a machine shell, a protective cover is installedat the corner of the upper end face of the machine shell, an air inlet is formed in one side of the protective cover, an air guide plate structure is obliquely arranged inside the protective cover, the air guide plate structure comprises an L-shaped connecting piece, a spring steel sheet, a linear air guide plate and an arc-shaped air guide plate, the spring steel sheet is fixed to the inner wallof the protective cover through the L-shaped connecting piece, and the spring steel sheet is inserted into the bottom of the linear air guide plate to be fixed. According to the ventilation and dustfiltration device for the motor of the washing machine, the designed air guide plate structure can guide the air feeding direction, dust is adsorbed through a filter bag, and therefore, the filtrationeffect is achieved; the designed spring steel sheet can be matched with vibration of the motor to enable the dust on the filter bag to be shaken off into a dust collection groove, so that the purposeof centralized collection is achieved; and a designed blocking cover prevents dust from overflowing, so that the device is suitable for different working conditions, and brings a better application prospect.

Description

technical field [0001] The invention relates to the field of external structures of motors, in particular to a ventilating and dust-filtering device for washing machine motors. Background technique [0002] The tiny particles in the cooling air that enter when the motor is working will cause damage to the insulation of the inner winding of the motor and affect the life of the motor. Therefore, the dust removal structure and device of the motor on the washing machine and its dust removal effect have attracted widespread attention; the existing Most washing machine motors rely on the air inlet to install a dust cover to meet the use requirements of clean cooling air. That is, the structure of the dust cover is to set several layers of filters at the air inlet, and the middle of the filter is filled with dense dust filter materials to achieve a certain dust filter effect. The structure is complex, the wind resistance is large, and the dust is easy to block the filter after it e...

[0002] The tiny particles in the cooling air that enter when the motor is working will cause damage to the insulation of the inner winding of the motor and affect the life of the motor. Therefore, the dust removal structure and device of the motor on the washing machine and its dust removal effect have attracted widespread attention; the existing Most washing machine motors rely on the air inlet to install a dust cover to meet the use requirements of clean cooling air. That is, the structure of the dust cover is to set several layers of filters at the air inlet, and the middle of the filter is filled with dense dust filter materials to achieve a certain dust filter effect. The structure is complex, the wind resistance is large, and the dust is easy to block the filter after it enters, and it is not easy to remove (it can only be removed manually), which affects the amount of cooling air entering, which in turn reduces the cooling effect and brings certain adverse effects during use. , for this reason, we propose a washing machine motor ventilation dust filter device
