Abstract
The utility model relates to a flow-ejecting inducing fan, which comprises a machine shell, a spiral shell, an impeller, a motor and an air inlet. The utility model is characterized in that the air outlet part of the spiral shell is provided with a flow guiding pipeline. The tail end of the flow guiding pipeline is provided with a nozzle and the direction of the nozzle can be adjusted. The utility model has the advantages that the installation cost of a ventilating pipeline is saved and ventilation can be conducted in an occasion that the ventilating pipeline can not be installed.
Description
Technical field
The utility model relates to a kind of blower fan, particularly a kind of jet Induced fan.
Background technique
The general ventilation equipment that uses in the heavy construction at present, existing ventilation equipment will could be delivered to new wind everywhere by ventilation duct is installed, but pipe laying needs certain project installation expense, and in some special places ventilation duct can't be installed, and there is the dead angle in ventilation.
Summary of the invention
The purpose of this utility model is to solve the general ventilation equipment that uses in the medium-and-large-sized building of prior art, existing ventilation equipment will could be delivered to new wind everywhere by ventilation duct is installed, but pipe laying needs certain project installation expense, and in some special places ventilation duct can't be installed, there is the problem at dead angle in ventilation.The utility model design jet Induced fan comprises casing, spiral case, impeller, motor, intake grill, and it is characterized in that: there is conduction pipe at the place at the spiral case exhaust outlet, and the end of conduction pipe has the direction adjustable nozzles.The utility model has the advantages that the mounting cost of saving ventilation duct, and can the occasion ventilation of ventilation duct can't be installed.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated, accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is a plan structure schematic representation of the present utility model
Comprise casing 1, spiral case 2, impeller 3, motor 4, intake grill 5 among the embodiment figure, it is characterized in that: there is conduction pipe 7 at 6 places at spiral case 2 exhaust outlets, and the end of conduction pipe 7 has direction adjustable nozzles 8.Fan motor 4 starts during use, and air sucks spiral cases 2 from intake grill 5, through impeller 3 pressurizations, flows into conduction pipes 7 by spiral case 2 exhaust outlets 6, has direction adjustable nozzles 8 that new wind is delivered to by the end of conduction pipe 7 again and changes Feng Chu, rice surplus novel wind energy send 10.
