Abstract
The utility model relates to an induced draft fan. The utility model comprises a centrifugal wind wheel, a wind exhaust channel and an outlet of the wind exhaust channel, wherein, an outlet is also arranged on a pipe wall of the wind exhaust channel, a movable wind door is correspondingly arranged on the outlet, and the movable wind door is in shaft connection with the pipe wall; after rotating, the movable wind door can close the wind exhaust channel arranged on the lower section of the utility model. The arranged movable wind door is skillfully utilized by the utility model; multidirectional wind exhaust is realized on the precondition that the sense of rotation of the centrifugal fan is not changed; the work of the centrifugal fan is identical with that of unidirectional wind exhaust, and thus, the wind exhaust efficiency of the centrifugal fan is equivalent to that of the unidirectional wind exhaust.
Description
The utility model relates to a kind of wind-guiding machine.
Existing wind-guiding machine utilizes centrifugal wind wheel vertically to suck air, air is laterally discharged again.This wind-guiding machine is realized two-way air draft at the most, and also can only adopt the method that changes blower fan turning, adopts its ventilation efficiency of the two-way air draft of this structure more unidirectional air draft to descend a lot because the structure of blade is limit.
The purpose of this utility model be to provide a kind of can not only be two-way and can multidirectional air draft, wind-guiding machine that ventilation efficiency is high.
For achieving the above object, the utility model is by the following technical solutions: it comprises centrifugal wind wheel, exhausting duct and outlet thereof, also be provided with outlet on the tube wall of exhausting duct, this outlet correspondence is provided with movable air door, this activity air door be connected with the tube wall axle and rotate after the exhausting duct in its downstream can be closed.
When adopting above technical scheme, the utility model also can adopt following further technical scheme:
Described exhausting duct is approximate spiral of Archimedes to launch.
Outlet on the described tube wall is an extensional pipeline of taking mouth out of.
Also be provided with outlet on the above-mentioned extensional pipeline wall, this outlet correspondence is provided with movable air door, this activity air door be connected with the tube wall axle and rotate after the extensional pipeline in its downstream can be closed.
Movable air door in the exhaust duct is provided with the travel switch of motor by driven by motor with respect to the limit of sports record point of movable air door.
Owing to adopted technique scheme, the utility model to utilize dexterously to be provided with movable air door to realize multidirectional air draft not changing the prerequisite that centrifugal blower turns to, and the work of centrifugal blower is identical with unidirectional air draft thereby ventilation efficiency is also suitable with unidirectional air draft.When the extensional pipeline wall also was provided with movable air door, air-out direction of the present utility model also can double and even several times.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is the schematic diagram of the utility model shell.
With reference to accompanying drawing.The utility model comprises centrifugal wind wheel 1, exhausting duct 2 and exports 3, exhausting duct 2 can be approximate spiral of Archimedes to launch, certainly also can be other formal expansion, but expand into goodly with approximate spiral of Archimedes, can make compact conformation can make the loss of blast reduce to minimum again like this; Also be provided with on the tube wall 8 of exhausting duct the outlet 5, this exports 5 correspondences and is provided with movable air door 4, this activity air door 4 be connected with 8 of tube walls and rotate after the exhausting duct in its downstream can be closed.Twice activity air door 4 is set in the present embodiment, adopts the technical solution of the utility model certainly, the quantity of movable air door is unrestricted.
Outlet 5 can be the extensional pipeline 7 of taking mouth 6 out of.
Adopt when taking mouthfuls 6 extensional pipeline 7 out of when outlet 5, extensional pipeline wall 13 also can be provided with outlet 9, and this exports 9 correspondences and is provided with movable air door 10, this activity air door 10 be connected with 7 of tube walls and rotate after the extensional pipeline 7 in its downstream can be closed.
Exhausting duct tube wall 8 and extensional pipeline wall 13 can be provided with weather strip 10 with its sealing function with respect to the limit of sports record point place of movable air door 4 and movable air door 10.
The rotation of movable air door 4,10 can be driven by motor 11, and the travel switch 12 of motor is set with respect to the limit of sports record point of movable air door 4,10 like this.
