Description

Technical Field

[0001] The utility model relates to the field of exhaust equipment, in particular to a side plate of a crossflow fan. Background Art

[0002] The cross-flow fan is a fan in which the impeller rotates under the drive of the motor, so that the air flows from the impeller inlet into the center of the impeller under the action of centrifugal force, forming a high-speed rotating airflow, and then flows out from the impeller outlet. At the outlet, the airflow enters the diffuser, undergoes static pressure rectification, and makes the airflow flow evenly to the fan outlet, while reducing the airflow speed and converting its kinetic energy into pressure energy. Finally, the airflow passes through the muffler to eliminate noise and is transported to various air-using points through the air duct.

[0003] For example, the Chinese utility model patent with application number: 2021109578943, the invention is named as an integrated crossflow fan, which discloses: "including an air duct shell, a wind wheel and a motor, the motor including a shaft, a stator and a rotor, the motor and the wind wheel are both arranged in the air duct shell; the shaft is fixedly connected to the inner side of the stator, and the rotor is arranged on the outer side of the stator; the rotor is connected to an end cover, and the end cover is connected to the shaft through a bearing; the wind wheel includes a bottom plate and blades arranged in a circular array along the central axis of the bottom plate, and the bottom plate and the end cover are injection molded as one piece", and the shell of the fan in the above technology is also That is, the air duct shell in the original text is C-shaped, and the wind wheel is cylindrical. When the wind wheel is installed on the air duct shell, most of the area of ​​the wind wheel will protrude from the air duct shell. When the crossflow fan needs to be repaired or cleaned, the crossflow fan needs to be disassembled, but most of the area of ​​the wind wheel will protrude from the air duct shell. Disassembly may cause the wind wheel to collide with other objects and deform. After the wind wheel deforms, it will vibrate when it rotates. In mild cases, abnormal noise will be generated, and in severe cases, the vibration is too large to damage the drive motor. In addition, when installing the drive motor and bearings and other parts due to the C-shaped air duct shell, the area at both ends of the air duct shell is small, so it is difficult to install and there is a risk of falling off.
