Abstract
The utility model discloses a ventilating duct of a central air conditioner. The ventilating duct comprises a main ventilating pipe, wherein the main ventilating pipe is vertically provided with a plurality of branch ventilating pipes, an air inlet of each branch ventilating pipe is provided with an air deflector, the included angle between each air deflector and the main ventilating pipe is 45 degrees, a grid plate is arranged in each branch ventilating pipe, and each grid plate is uniformly provided with air outlet holes. Compared with an existing air duct, the main ventilating pipe of the ventilating duct is vertically provided with the branch ventilating pipes, the air inlets of the branch ventilating pipes are provided with the air deflectors to guide airflows to enter the branch ventilating pipes, the included angle between each air deflector and the main ventilating pipe is 45 degrees, the air inducing effect is good, the grid plates are arranged in the branch ventilating pipes, the grid plates are uniformly provided with the air outlet holes to filter turbulent airflows into laminar flows and filter fly ash, and each grid plate is in an arc shape, and has a large contact area and a good filtering effect.
Description
Technical field
The utility model relates to a kind of ventilation duct, relates in particular to a kind of central air-conditioning ventilation shaft.
Background technology
Existing ventilation shaft is simple in structure, and efficient is lower, and air is easy to produce turbulent flow in flowing, and causes branch vent self shake, and ventilating system when opening the deposition ash in the pipeline be easy to take out of with the wind contaminated environment.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of central air-conditioning ventilation shaft that has solved above problem.
The technical solution of the utility model is: a kind of central air-conditioning ventilation shaft, comprising ventilates is responsible for, described ventilation vertically is provided with several branch vents on being responsible for, described branch vent air inlet place is provided with wind deflector, described wind deflector is 45 ° with the angle of being responsible for that ventilates, be provided with waffle slab in the described branch vent, evenly offer venthole on the described waffle slab.
As preferably, described waffle slab is curved.
As preferably, described branch vent is two or more.
The beneficial effects of the utility model are: ventilation described in the utility model vertically is provided with several branch vents on being responsible for, described branch vent air inlet place is provided with wind deflector, and steering current enters branch vent, and described wind deflector is 45 ° with the angle of being responsible for that ventilates, blower effect is good, be provided with waffle slab in the described branch vent, evenly offer venthole on the described waffle slab, will filter turbulent airflow and become advection, filter flying dust, described waffle slab is curved, and contact area is big, good filtration effect.
