Abstract

The utility model discloses a transverse flow double direction air exhausting fan which belongs to a household appliance, mainly comprising a motor, a casing, an impeller, a top frame and a volute matched with the inner of the casing. The transverse flow double direction air exhausting fan is characterized in that the casing is provided with two air inlets and two air outlets, the volute is provided with an air inlet and an air outlet, and the volute is movably matched with the casing in an axial direction. The volute can axially rotate certain angle to select one air inlet and one air outlet and simultaneously isolate the other air inlet and the other air outlet. The transverse flow double direction air exhausting fan has the advantages of artful design, reasonable structure, low noise and large air quantity, and the transverse flow double direction air exhausting fan can achieve bidirectional air exchange and ideal air inlet and outlet effect without changing the steering and speed of the impeller.

Description

Transverse flow double direction air exhausting fan
The utility model belongs to a kind of household electric appliance, relates to a kind of cross-flow type dual direction ventilating fan.
Existing dual direction ventilating fan mostly is a kind of axial flow fan, by the forward or reverse of motor, the characteristic of fan blade reaches the purpose of air inlet or exhaust, owing to can only be designed a kind of steering behaviour fan blade preferably, if the counter-rotating fan blade, air quantity will reduce, and noise increases.During use, can only turn down motor speed and overcome strong noise, but so just make that air quantity reduces again, therefore itself also there is its irrational one side in design in existing dual direction ventilating fan.
The purpose of this utility model is to overcome the defective of above existence, and the structure of existing dual direction ventilating fan is improved, and provides a kind of and need not change that impeller turns to, speed, just can reach the cross-flow type dual direction ventilating fan of inlet and outlet purpose.
This cross-flow type dual direction ventilating fan, mainly comprise motor, casing, impeller, face frame and with casing in the spiral case of joining.The designer improves to casing structure and with the combination of spiral case.Have two groups of suction ports and relief opening on the casing and with the arbor Vertical direction, spiral case is provided with one group of inlet, outlet, and the axial activity of casing and spiral case connects.But spiral case axial rotation several angle is selected one group of suction port and relief opening, isolated simultaneously another group suction port and relief opening.
Described cross-flow type dual direction ventilating fan designs ingenious, rational in infrastructure, need not change that impeller turns to, under the situation of speed, just can realize two-way ventilation, and inlet and outlet all reach comparatively ideal effect, noise is low, air quantity is big, thereby realizes the purpose of this utility model.
Below in conjunction with Figure of description, the utility model is described in further detail.
Fig. 1 is a cross-flow type dual direction ventilating fan structural representation.
Fig. 2, Fig. 3 are dual direction ventilating fan user mode figure.
Motor 7, speed control switch 8 are installed in the motor protective case 6, and motor protective case 6 is fixed on casing 2 the right, and impeller shaft-cup 13 is fixed on casing 2 left sides, and 5 in impeller inserts interior the living of axle sleeve of impeller shaft-cup 13 joins, and the other end and motor shaft connect.Spiral case 4 is installed in the casing 2 and with casing 2 work joins, but spiral case axial rotation several angle is selected one group of suction port and relief opening, isolated simultaneously another group suction port and relief opening.Blow formula blinds 3 upper ends two pins and 2 alive joining of casing open, the outer side-inlet on the casing 2 is installed a screen cloth 12.Spiral case 4 one end faces are provided with positioning work piece 14, and the other end has the cylinder of two protrusions.Positioning work piece 14 is made up of plug screw, spring, steel ball, be installed in the impeller shaft-cup 13 and with spiral case 4 end faces on two circular holes make positioning action.Triangle weighs down backguy 10 and rectangular and weighs down that backguy 11 is connected on two cylinders that spiral case 4 end faces protrude two protrusion cylinders and the end face center of circle is preferably 90 ° of positions, is used to rotate spiral case 4, to select air inlet or exhaust.The circular backguy 9 connection backguy speed control switchs 8 that weigh down, face frame 1 covers casing 2 and motor protective case front and close-fitting.

Claims (2)

1, a kind of cross-flow type dual direction ventilating fan, mainly comprise motor (7), casing (2), impeller (5), face frame (1) and with casing (2) in the spiral case (4) of joining, it is characterized in that casing (2) upward and with the arbor Vertical direction has two groups of suction ports and relief opening, spiral case (4) is provided with one group of inlet, outlet, and casing (2) connects with the axial activity of spiral case (4).
2, a kind of cross-flow type dual direction ventilating fan as claimed in claim 1 is characterized in that spiral case (4) one end faces are provided with positioning work piece (14), and the other end has the cylinder of two protrusions.
