Abstract
The utility model discloses a non-duct inducing fan, which comprises a housing and a cover plate. A motor and a worm fan arranged therewith are arranged in the housing; a first partition board and a second partition board which are basically perpendicular are arranged in the housing, wherein the second partition board is parallel to a lateral board, and divides the fan into two chambers; a gas accumulating chamber is formed between the second partition board and the housing with an air duct interface arranged thereon; the other room is divided into an anterior chamber and a posterior chamber;the worm fan is arranged in the anterior chamber; the motor is arranged in the posterior chamber; and an air outlet is formed at the lower part of the second partition board in the anterior chamber. As the aerodynamic principles are applied to drive the air flow, and gradually increase the induced air capacity at the periphery, the non-duct inducing fan is suitable for being mounted in the underground space and can be arranged easily and flexibly; the induced air is completely circulated, so that no dead space exists, and the accumulation of pollution can be avoided, thereby improving the airquality; and not more air ducts are required to be mounted, so that the floor height of an underground garage can be lowered, and the construction cost can be saved.
Description
Technical field
The utility model relates to a kind of no airduct Induced fan.
Background technology
In some buildings,,, often need to install blower fan to improve indoor air quality because the ventilation condition of self is limited such as gymnasium, market place builet below the ground, underground garage etc.Existing blower fan kind is a lot, is centrifugal type mostly, and many crisscross airducts are installed, and this device exists a lot of weak points: there is the dead angle of foul atmosphere in the airduct ventilating system, and it is not thorough to take a breath; Airduct ventilating system cost height, it is bigger to take up room, and takes electricity, not energy-conservation; The airduct ventilating system is installed complicated, is difficult for investigation, safeguards very difficult; For these crisscross airducts are installed, often need to increase the floor height of underground garage, the waste construction cost.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of no airduct Induced fan.
The technical solution of the utility model is such: a kind of no airduct Induced fan, comprise housing and cover plate, and the snail fan that in housing, is provided with motor and is set together with motor, be provided with vertical substantially first dividing plate and second partition in the described housing, wherein second partition is parallel to the side plate setting, and blower fan is divided into two Room; Described second partition and be provided with between the housing of duct collar and constitute air storage chamber, another chamber is divided into cup and chamber, back by first dividing plate; Described snail fan is arranged in the cup, and it is indoor that described motor is arranged on the back; The bottom of second partition is provided with air outlet in the described cup.
In the described cup spiral case is set, snail fan is arranged in the described spiral case, and the spiral case lower ending opening also is communicated with described air outlet.The side plate of chamber, described back is provided with the air intake grid, also is provided with the air intake grid on the cover plate of chamber, described back; First dividing plate between described motor and the snail fan is provided with fresh air inlet, and described air intake grid and fresh air inlet constitute air inlet system jointly.Described motor is fixed on first dividing plate by electric machine support, and the end of motor shaft is provided with snail fan support, and the base portion of described snail fan is fixed on the snail fan support.
No airduct Induced fan utilization aerodynamic principle with the disturbance characteristic of a small amount of high speed jet gas, comes a large amount of still airs of inducing peripheral, thereby drives circulation of air.Under the prerequisite of no airduct, the central speed of jet flow is risen gradually by air outlet and reduces, but the width of jet flow increases also increase gradually of the air capacity of being induced on every side gradually.No airduct Induced fan need not to install so much airduct, can reduce the floor height of underground garage, saves building cost.
Adopt technique scheme, the beneficial effect that brings to the utility model is: structure is comparatively simple, and compactness is in light weight, need not airduct; Be applicable to the installation of the underground space, can select the air-out of one or more direction jet flow arbitrarily, be easy to flexible arrangement; Duct collar can be done 360 ° adjustment as requested, induces gas to circulate fully, can not produce the dead angle, avoids pollution accumulation, improves air quality more.
