Mixed flow fan and range hood including same

Abstract

The invention discloses a mixed flow blower and a range hood comprising the mixed flow blower. The mixed flow blower is applied to the range hood, and comprises a shell, a motor and impellers connected onto a drive shaft of the motor. The impellers and the motor are arranged on the inner side of the shell; and an oil guiding structure is arranged on the shell and is used for guiding oil contaminations on an inner wall of the shell so as to enable the oil contaminations to flow into an oil contamination collecting structure of the range hood. According to the mixed flow blower provided by the invention, through arranging the oil guiding structure, an oil guiding function of the mixed flow blower is realized, and the oil contaminations on the inner wall surface of the mixed flow blower can be effectively guided out so as to be prevented from dropping on a surface of a cooking bench, so that a use effect of a user cannot be affected.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a mixed flow fan and a range hood comprising the same. Background technique [0002] At present, the range hoods of most household users in middle and high-rise buildings are connected to the public flue through the exhaust pipe to exhaust the smoke. When the size of the public flue is small, or there are many range hoods working at the same The resistance in the flue will be very large, which will affect the smoke exhaust effect of the user's range hood. The method to break through the resistance of the flue is nothing more than increasing the air volume of the range hood and increasing the wind pressure. For example, a range hood equipped with a mixed flow fan can greatly increase the wind pressure, but this mixed flow hood has a special structure: The wind and the wind come out from the top, and the lowest point is inside the air duct, so it cannot guide oil.

[0002] At present, the range hoods of most household users in middle and high-rise buildings are connected to the public flue through the exhaust pipe to exhaust the smoke. When the size of the public flue is small, or there are many range hoods working at the same The resistance in the flue will be very large, which will affect the smoke exhaust effect of the user's range hood

The method to break through the resistance of the flue is nothing more than increasing the air volume of the range hood and increasing the wind pressure. For example, a range hood equipped with a mixed flow fan can greatly increase the wind pressure, but this mixed flow hood has a special structure: Wind and upward air flow, the lowest point is inside the air duct, so it cannot conduct oil
