Problems solved by technology

At this time, the ambient temperature of the motor is 70-80°C, and the outer casing is not much different from the ambient temperature, which will cause the motor to fail to dissipate heat.
When the motor winding works in a temperature environment of about 90°C for a long time, the motor cannot be effectively cooled, which affects the operating life of the motor, thereby affecting the reliability and life of the dryer.

Abstract

The invention relates to a motor cooling component, a control method, a control device and electrical equipment and belongs to the technical field of motor cooling. The motor cooling component comprises multiple cold air ducts, wherein each cold air duct can output one path of cold air capable of reaching a motor; the reachable positions, of the cold air output from various cold air ducts, on themotor are different; and uniformly distributed cooling for the motor is formed by multiple paths of cold air output from the multiple cold air ducts. Through the motor cooling component, reduction ofthe temperature of the motor during high-speed operation is facilitated to prolong the operating life of the motor.

Description

technical field [0001] The application belongs to the technical field of motor cooling, and specifically relates to a motor cooling component, a control method, a control device and electrical equipment. Background technique [0002] For wet laundry, it can be dried in a dryer. According to the demand of drying temperature. It can be divided into three categories: low, medium and high temperature. According to the statistics of the current differences in climate data in various regions of the country, most dryers work in the medium or high temperature range for a long time. When the dryer is running in the medium temperature or high temperature section, the temperature in the dryer will stay at 70-80°C for a long time. At present, when the drum motor used in most dryers is running at high speed, the winding temperature will reach about 90°C for a long time. At this time, the ambient temperature of the motor is 70-80°C, and there is not much difference between the outer c...
