Background

The existing food processing machines such as wall breaking machines and food processing machines adopt a high-speed motor as a power source, and the rotating speed of the motor is more than 20000 rpm. The high-speed rotation of the motor generates more heat, so that the motor needs to be cooled. The existing scheme adopts an air cooling mode. The motor fan blades rotate at a high speed, outside air is sucked into the main machine from the air inlet, a part of heat is taken away, and the outside air is discharged from the air outlet.

Most of the existing air outlets adopt a grid structure, and air flows along the direction of a motor shaft and can directly reach the position of the air outlet. In order to meet the safety requirements, the distance between the grids of the air outlet is often smaller. Because the motor rotating speed is higher, the air discharge amount is larger, and when air flowing at high speed passes through the air outlet grids, more vortex flows are generated, and larger noise is formed. In addition, as shown in fig. 1, the central position of the air outlet has a larger area without holes, which generates larger resistance to air and reduces the air exhaust amount; on the other hand, after the air flows through the surroundings, more eddy flows are formed below the air, and noise is generated. Meanwhile, after flowing air passes through the air outlet, the flowing air can vertically strike the supporting surface of the machine, so that large wind resistance is generated, and the heat dissipation efficiency is reduced.
