Description

Low noise air-conditioning draught fan

Technical field

This utility model relates to blower fan technical field, particularly relates to a kind of low noise air-conditioning draught fan.

Background technology

Currently used air-conditioning draught fan has following deficiency: 1, the blade of the impeller of air-conditioning draught fan uses with shroud, hub disk Being welded to connect, weld job makes poor working environment, and product appearance is unsightly；2, the wind collecting unit air spots of air-conditioning draught fan is sliding, Cause that air intake resistance is big, efficiency is low；3, efficiency of blowing in the running of air-conditioning draught fan is low.

Summary of the invention

In order to solve deficiency of the prior art, the purpose of this utility model is to provide a kind of low noise air-conditioning draught fan, It is optimized design by construction package each to product, improves product combination property and technical specification.

This utility model solves its technical problem and be the technical scheme is that

A kind of low noise air-conditioning draught fan, the spiral case including main body rack, being arranged in main body rack, is arranged in spiral case Impeller, the main shaft two ends of impeller are connected fixing by bearing with main body rack, are provided with air outlet, the two of spiral case on the upside of spiral case front end It is equipped with air inlet on individual sidewall, it is characterised in that: the blade two ends of described impeller are respectively with its shroud, hub disk riveting even Connecing, the wind collecting unit of spiral case both sides air inlet is to seamlessly transit structure by mould punching molding, inside two wind collecting units all Being provided with air-supply inner core, air-supply inner core and wind collecting unit and connected by connecting rod fixing, the outer end of air-supply inner core is to put down with wind collecting unit The flare openings structure and aperture area is wind collecting unit aperture area the 1/2 of its outer end that row is arranged, the interior of inner core of blowing End is flare openings structure and its inner end and impeller inwall interval 3-5cm is arranged.

The 1/4 of a length of impeller length of described air-supply inner core, the outer end of air-supply inner core and spiral case side are positioned at same In one plane.

The beneficial effects of the utility model are:

1, the blade two ends of impeller are connected by rivet with its shroud, hub disk respectively, the most singly improve product appearance Quality and aesthetic measure, be also greatly improved firmness and the assembly precision quality of product, make impeller carry in running up High safety reliability, it is ensured that impeller stability in operation process.

2, wind collecting unit uses advanced UG Design of Dies and the diel of making, makes stamping forming wind collecting unit surface light Sliding circular curve transition, improves the smooth degree of spiral case both sides air intake, substantially increases airflow pressure and the blower fan effect of blower fan Rate.

3, arranging of inner core of air-supply can make the intake of air inlet effectively distribute, make the inner wall surface of impeller with Air is fully contacted, and improves the air-supply efficiency of air-conditioning draught fan, reduces operation cost.
