Description
Technical field
The present invention relates to a kind of fan assembly.
Background technique
The Chinese patent application that on May 6th, 2009, publication number was CN 101424279A (application number: 200810177844.8) disclose a kind of no blade fan device that is used to produce air stream, described fan assembly comprises nozzle and the member that is used to produce by the air-flow of described nozzle, described nozzle comprises the inner passage, be used to receive from the relief opening of the air-flow of described inner passage and the coanda surface that is close to described relief opening location, described relief opening is set to steering flow and flows through described coanda surface, described nozzle limits an opening, and described fan assembly air outside is entrainmented from the air-flow that relief opening sprayed by this opening.
This kind fan assembly is close to the coanda Surface runoff of next-door neighbour's relief opening location from the quick air-flow that relief opening sprayed, or inject directly on the described coanda surface, violent rubbing action between the air-flow of its rapid movement and the described coanda surface not only causes the energy loss of the air-flow that is sprayed, and produces very big noise.
Summary of the invention
The present invention aims to provide a kind of improved fan assembly to overcome above-mentioned defective of the prior art.The objective of the invention is to provide the no blade fan device that a kind of noise is low, efficient is high.
In order to achieve the above object, the technical solution used in the present invention is: the no blade fan device that is used to produce air stream, described fan assembly comprises: nozzle and the member that is used to produce by the air-flow of described nozzle, described nozzle comprises the inner passage that is used to receive air-flow, be used to receive relief opening from the air-flow of described inner passage, be used for the training wall of steering flow and the spacing wall that is used to locate, wherein, described spacing wall is arranged between described relief opening and the described training wall, makes described relief opening and described training wall in the certain spacing of being separated by perpendicular to the direction of axis.
Described nozzle can not limit opening, described relief opening can be arranged on nozzle around on the wall, entrainmented by the air-flow that relief opening sprayed of wall around be positioned at from described fan assembly air outside; Described nozzle can limit at least one opening, is entrainmented from the air-flow that relief opening sprayed by described opening from described fan assembly air outside.
Described relief opening and described training wall in the spacing of being separated by perpendicular to the direction of described axis usually between 1 millimeter to 15 millimeters, preferably between 3 millimeters to 10 millimeters.
The Way out of described relief opening and the angle of described axial direction are usually between 0 degree is spent to 30, preferably between 0 degree is spent to 20.
Described relief opening is generally slot-shaped relief opening, described relief opening at the width in its outlet port usually between 1 millimeter to 10 millimeters, preferably between 1 millimeter to 6 millimeters.
Along on the cross section of described axis, described training wall can be one section curve, also can be one section straight line, the angle of described straight line and described axis usually at 0 degree between 20 degree.
Described nozzle along the size of described axial direction usually between 50 millimeters to 350 millimeters, preferably between 60 millimeters to 250 millimeters.
Described training wall along the size of described axial direction usually between 50 millimeters to 300 millimeters, preferably between 50 millimeters to 150 millimeters.
Described member can comprise AC induction motor, also can comprise dc brushless motor.
The present invention has following good effect:
Because apparatus of the present invention are not close to the coanda surface of relief opening location, the quick air-flow that sprays from relief opening can not take place because and the violent rubbing action between next-door neighbour's the coanda surface cause energy loss and the very big noise of generation.Apparatus of the present invention are provided with the spacing wall setting between relief opening and training wall, make relief opening and training wall in the certain spacing of being separated by perpendicular to the direction of axis, like this from air-flow that relief opening sprayed, not being close to training wall at its air-flow of incipient stage flows, the air-flow in this stage has the feature of free jet, can not produce very big noise and energy loss; In follow-up phase, the air-flow that air-flow that is sprayed and quilt are entrainmented is because the existence of training wall is just mobile near training wall gradually.Therefore, apparatus of the present invention greatly reduce the noise that is produced and have reduced frictional loss.
