Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a motor bracket and a range hood. Background Art

[0002] The range hood mainly relies on the centrifugal force of the fan to throw the oil smoke out of the kitchen operation area, but the centrifugal force is provided by the motor excitation source. If the vibration of the motor is large, or there is a sudden change in the vibration within a frequency band, the impact will be transmitted to the volute rear cover through the motor bracket, and the volute rear cover is directly transmitted to the whole machine through a rigid connection, causing the vibration of the whole machine and generating vibration noise. Since the motor is the excitation source and the motor bracket is the fixed structure of the motor, it determines the probability that the vibration of the motor can be transmitted to the whole machine. Therefore, improving the reliability of the motor bracket is particularly important in reducing vibration transmission and reducing the risk of abnormal noise. Utility Model Content
