Description
Technical field
The utility model relates to the structure member technical field of air-conditioner, refers more particularly to a kind of noise-lowering centrifugal wind wheel.
Background technology
Centrifugal wind wheel is widely used in various conditioner, particularly in air-conditioning cleaner, cabinet type detachable air conditioner, the product such as machine, window machine, mobile air conditioner, dehumidifier uses in a large number.Generally speaking, we require that pressure fan is low in energy consumption, and air quantity is large, and noise is low, and these three indexs are used to the principal element weighing pressure fan performance quality.
The noise that traditional centrifugal wind wheel spiral case produces mainly comprises air inlet noise, spiral case noise, fan noise, wherein fan noise comprises Rotation Noise and eddy current noise, eddy current noise refers to that centrifuge blade is when rotating, ambient gas is made to produce eddy current, these eddy current, due to the effect of viscosity, are divided into again a series of discrete little eddy current, and eddy current and eddy current divide makes air generation disturbance, form compression and sparse process, thus produce noise.For air-conditioner centrifugal wind wheel, eddy current crack accounts for major part.
Application number is that the Chinese patent of CN201420243983.7 discloses a kind of high-efficiency air-condition centrifugal blower, comprise base, spiral case and wind wheel, two power transmission shaft is individually fixed in the wind wheel in spiral case, spiral case and motor are fixed on base, the setting angle of the blade of wind wheel is 30 °-40 °, if adopt this patent, in actual use, setting angle due to the centrifuge blade of centrifugal wind wheel is fixing, nonadjustable, can not be adjusted accordingly according to the change of blast, wind pushing performance is poor, when blast is large, air-supply will reduce the service life of centrifugal wind wheel by force, produce harsh noise, reduce the overall quality of air-conditioning, can not meet the demand of client.So be badly in need of improving the deficiencies in the prior art.
Summary of the invention
The purpose of this utility model solves above-mentioned Problems existing.
The utility model is achieved in that a kind of noise-lowering centrifugal wind wheel, comprise housing, housing upper left end is provided with air outlet, on the left of the bottom of air outlet and housing, the junction of outer end is provided with snail tongue, it is characterized in that: described enclosure interior is provided with centrifugal wind wheel, be provided with gap between centrifugal wind wheel and inner walls, centrifugal wind wheel is evenly distributed in several arc wind wheel blades, and wind wheel blade realizes synchronous adjustment by linkage.
The adjustable angle of wind wheel blade described in the utility model is α, α is 45 °-55 °.
Gap between centrifugal wind wheel described in the utility model and inner walls is d, d is 2mm-8mm.
Wind wheel blade described in the utility model is arcwall face, and unified to deflecting clockwise or counterclockwise.
Snail tongue described in the utility model is higher than the center of centrifugal wind wheel.
The material that housing described in the utility model adopts is that galvanizing is without zinc card.
The utility model simplicity of design, rationally, low-power consumption, can adjust the angle of centrifuge blade, the gap between housing and centrifugal wind wheel timely according to the change of blast, not only improve wind pushing performance, and improve the service life of centrifugal wind wheel, reach the effect reducing noise simultaneously, meet the demand of client.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, a kind of noise-lowering centrifugal wind wheel, comprise housing 4, housing 4 upper left end is provided with air outlet 1, on the left of the bottom of air outlet 1 and housing 4, the junction of outer end is provided with snail tongue 3, it is characterized in that: described housing 4 inside is provided with centrifugal wind wheel 2, is provided with gap between centrifugal wind wheel 2 and housing 4 inwall, centrifugal wind wheel 2 is evenly distributed in several arc wind wheel blades 201, and wind wheel blade 201 realizes synchronous adjustment by linkage; The described adjustable angle of wind wheel blade 201 is α, α is 45 °-55 °; Gap between described centrifugal wind wheel 2 and housing 4 inwall is d, d is 2mm-8mm; Described wind wheel blade 201 is arcwall face, and unified to deflecting clockwise or counterclockwise; Described snail tongue 3 is higher than the center of centrifugal wind wheel 2; The material that described housing 4 adopts is that galvanizing is without zinc card.
During concrete enforcement, air-flow enters housing 4, and centrifuge blade 201 rotates to be sent air-flow from air outlet 1.When blast increases, the angle of centrifuge blade 201 reduces, and housing 4 increases with the gap of centrifugal wind wheel 2; When blast reduces, the angle of centrifuge blade 201 increases, and housing 4 reduces with the gap of centrifugal wind wheel 2; Be not difficult to find out from foregoing, the utility model not only improves wind pushing performance, and improves the service life of centrifugal wind wheel, reaches the effect reducing noise simultaneously, meets the demand of client.
The utility model adopts ultra-wide angle spiral case, centrifugal multiblade welding wind wheel, and every platform all passes through strict dynamic and static balance adjustment; Housing 4 of the present utility model adopts galvanizing without zinc card, has excellent waterproof and dustproof, Corrosion Protection, can normally work under dark wet environment.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; some improvements and modifications can also be made; these improvements and modifications also should be considered as protection domain of the present utility model, and all available prior art of each part not clear and definite in the present embodiment is realized.
