Abstract
The utility model provides a window type air conditioner centrifugal fan, consisting of a wheel disc and a plurality of vanes with one end of each to be connected with the wheel disc. The utility model is characterized in that the length of the vane is more than half of the radius of the wheel disc; the other end of each vane is connected with an air deflector ring coaxial with the wheel disc; the air deflector ring is extended outward from the end in connection with the vanes and the extended part of the air deflector ring is a round necked opening with diminishing diameters. The utility model solves the technical problems of high noise and low efficiency of the existing window type air conditioner centrifugal fan.
Description
Technical field
The utility model belongs to a kind of improvement of fan structure, is a kind of window air conditioner centrifugal cutter specifically.
Background technique
Existing window air conditioner centrifugal cutter is to be made of wheel disc and the blade that is connected with wheel disc, and its blade quantity is more, and length of blade is less than half of wheel disc radius.Like this, air-flow turns back to intakeport from the fan edge easily, and the noise of generation is big, and fan efficiency is lower.
Summary of the invention
The utility model is that will to solve existing window air conditioner centrifugal cutter noise big, the technical problem that fan efficiency is low.
The technical solution of the utility model is: a kind of window air conditioner centrifugal cutter, comprise that a plurality of blades that a wheel disc and an end are connected with wheel disc constitute, it is characterized in that described length of blade greater than half of wheel disc radius, the blade the other end connect one with the air-ducting ring of wheel disc coaxial inner conductor.
Described air-ducting ring stretches out from the end that links to each other with blade, and the air-ducting ring extension is diminishing circular closing in of diameter.
Described blade inboard is a hypotenuse.
Described blade is that the 5-8 sheet all is vertically set on the wheel disc same side, and blade sense of rotation inclination dorsad, makes projection and the wheel disc radial ray of blade on wheel disc that certain angle be arranged.
The utility model compared with prior art has many advantages and good effect: the utility model adopts big blade, and the blade inboard is hypotenuse, can increase air quantity.Because of blade sense of rotation inclination dorsad, when fan moved, the blast pressure head was little, and noise is low; In the air-ducting ring of blade the other end connection one with the wheel disc coaxial inner conductor, during operation, the draft of fan is more concentrated, simultaneously, also can effectively stop air-flow to turn back to intakeport from the fan edge, thereby improve fan efficiency.
