The invention provides a fan and a range hood, and relates to the technical field of kitchen appliances. The fan comprises a volute, an impeller and a driving device; the volute comprises a coaming and two side plates arranged in a spaced mode, the coaming is arranged between the two side plates, the coaming and the two side plates jointly form an air duct, and the side plates are provided with air inlets; the impeller is arranged in the volute and connected with a driving shaft; and the driving device comprises a driving part and a transmission part, the driving part is installed on the outerwall of the coaming, and the transmission part is connected to the position between the driving end of the driving part and the driving shaft. The range hood comprises a box body and the fan, and thefan is installed in the box body. Pollution of oil contamination to the driving part in the fan is small, and the service life is long.
Description
technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a fan and a range hood. Background technique [0002] The range hood is a purification device widely used in the kitchen. The fan in the range hood operates to generate negative pressure, which sucks the fume from the kitchen side into the fan, and transports the fume to the public flue through the exhaust pipe. Therefore, the fan is a fume collector. The core component of the range hood, its effect directly determines the purification effect of the range hood on the range hood. [0003] During the operation of the existing range hood, the oil pollution caused by the oil fume flow to the motor of the fan is relatively serious, resulting in a decrease in the operating efficiency of the motor and a shortened service life. Contents of the invention [0004] The purpose of the present invention is to provide a fan and range hood to solve the technical problems in the pr...
