Abstract
The utility model relates to a low-noise central air conditioner fan, comprising a casing, a vane wheel and a leaf blade on the vane wheel. The utility model is characterized in that the leaf blade is composed of two arched pieces, one arched piece of the leaf blade is inwards concave, and the other arched piece is outwards convex; the cross section of the leaf blade is in the shape of an aerofoil, ribs are arranged on the two arched pieces, and the direction of the ribs is the rotation direction of the leaf blade. The utility model has the advantage that the noise of a central air conditioner can be lowered.
Description
The utility model relates to a kind of central air-conditioner blower fan, particularly a kind of low noise central air-conditioner blower fan.
The noise of the centrifugal blower that at present general central air-conditioner blower fan adopts is bigger, mainly is that the blade flow-disturbing is caused.
The purpose of this utility model provides a kind of low noise central air-conditioner centrifugal blower of tool fluid blade.
The technical solution of the utility model is a kind of low noise central air-conditioner blower fan of design, comprise the blade on casing, impeller, the impeller, it is characterized in that: blade is that two camber sheets constitute, a slice camber sheet indent of blade, another camber sheet is an evagination, the cross section of blade is a wing blade, on the two camber sheets muscle is arranged, and the direction of muscle is the blade rotation direction.
The utility model has the advantages that the noise that can reduce the central air-conditioner blower fan.
Below in conjunction with accompanying drawing the utility model is elaborated,
Accompanying drawing 1 is an impeller schematic perspective view of the present utility model,
Accompanying drawing 2 is a blade structure schematic representation of the present utility model,
Accompanying drawing 3 is A-A cut-away view of the utility model Fig. 2,
Comprise the blade 3 on casing, impeller 1, the impeller 1 among the figure, it is characterized in that: blade 3 is that two camber sheets constitute a slice camber sheet 4 indents of blade 3, another camber sheet 5 is an evagination, the cross section of blade 3 is a wing blade, on the two camber sheets 4,5 muscle 2 is arranged, and the direction of muscle 2 is blade 3 sense of rotation.
Owing to the transversal mask wing blade of blade 3, therefore blade 3 has good air flow channel shape when rotating during use, and noise is minimum during work.
