Easy-maintenance axial flow smoke fan with inlet air and outlet air in different directions

Abstract

The invention provides an easy-maintenance axial flow smoke fan with inlet air and outlet air in different directions. The easy-maintenance axial flow smoke fan comprises an axial flow air drum, a motor, a fan body, a shaft and a motor base. The axial flow air drum comprises an extending drum, an air inlet drum and an air discharging drum which are communicated with one other. The axis of the air inlet drum and the axis of the air discharging drum intersect, the extending drum is arranged at a communication position of the air inlet drum and the air discharging drum, the axis of the extending drum is coincided with the axis of the air discharging drum, the motor base is connected with the extending drum in detachable mode, the motor is arranged on the motor base, the motor is connected with the fan body through the shaft, the axis of the shaft is coincided with the axis of the air discharging drum, and the fan body is arranged in the air discharging drum. The easy-maintenance axial flow smoke fan with the inlet air and the outlet air in different directions has the advantages of remaining and developing the advantages of an axial flow fan of being large in air quantity and simple in structure and changing an inherent feature of a traditional axial flow fan of being same in air inlet direction and the air discharging direction. The motor is externally arranged and can not be smoked by oily smoke, and the motor and the fan body are convenient to detach, install, clean and maintain. The easy-maintenance axial flow smoke fan is favorable for being applied to the field of range hoods, especially the field of ceiling range hoods.

Description

technical field [0001] The invention relates to an oil fume fan, in particular to an easy-maintenance axial flow oil fume fan with opposite directions of air intake and exhaust. Background technique [0002] The invention of the curved tube axial flow oil fume fan has realized the change of the same inherent characteristics of the traditional axial flow fan with the same air intake and exhaust directions. The inherent feature of the same wind direction supports its application in the field of range hoods, especially in the field of top suction range hoods, and provides a brand new and valuable axial flow fan that can act as a range hood fan for the range hood field . [0003] However, the motor of the curved tube axial flow oil fume blower is still installed inside the air duct, and has been subjected to oil fume for a long time. The working environment is harsh, and it is prone to failure, which affects the service life; The parts with the most severe immersion in oil fum...

Problems solved by technology

[0003] However, the motor of the curved tube axial flow oil fume blower is still installed inside the air duct, and has been subjected to oil fume for a long time. The working environment is harsh, and it is prone to failure, which affects the service life; The parts with the most severe immersion in oil fume will easily cause the dynamic balance of the fans to deteriorate, resulting in increased noise and reduced air extraction and exhaust efficiency; in order to eliminate such adverse effects, it is necessary to clean the fans frequently, because The fan body and the motor are installed inside the fan cylinder, which is inconvenient to disassemble and assemble. Therefore, it is difficult to carry out regular cleaning of the fan body, as well as the maintenance of the motor and motor bearings. Once the fan fails, its maintenance is also quite difficult.
