Abstract
The utility model discloses a silent through-flow indoor ventilator. The indoor ventilator comprises a motor, wherein a left ventilating pipe connecting pipe and a right ventilating pipe connecting pipe are respectively fixed on the left side plate and the right side plate of a box body; a fan drum bracket is fixed in the box body; a fan drum is fixed on the fan drum bracket; the motor is fixed on the fan drum bracket; a wind wheel is fixed on a rotating shaft of the motor; the wind wheel is arranged in the fan drum; the fan drum is provided with a left part air inlet; the fan drum is connected with the right ventilating pipe connecting pipe through a pipeline; the left ventilating pipe connecting pipe is connected with the box body; a layer of silencing sponge is adhered and fixed on the inner wall of the box body; a plurality of silencing slots are formed in the silencing sponge. The indoor ventilator is low in noise and uniform in air supplied to the interior of the pipeline, and cannot cause uniformity in air supplied to the pipe and cannot cause noise.
Description
Technical field:
The utility model relates to blower fan technical field, more specifically to ventilator used in a kind of room ventilation road.
Background technique:
Existing indoor ventilator, the ventilator adopting in ventilation flue in parlour is most is axial-flow blower, its deficiency is: general axis flow fan exists the problem that noise is large, simultaneously inhomogeneous to the wind of sending in pipeline, easily causes room ventilation pipeline and produces sound.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of quiet tubular indoor ventilator is provided, and its noise is little, in pipeline, blows evenly, can not cause pipeline and because of uneven air, produce sound.
Technology solution of the present utility model is as follows:
Quiet tubular indoor ventilator, comprise motor, on the left sideboard of casing and right sideboard, be fixed with respectively left ventilation duct adapter and right ventilation duct and take over, in casing, be fixed with air duct support, on air duct support, be fixed with air duct, motor is fixed on air duct support, in the rotating shaft of motor, be fixed with wind wheel, wind wheel is placed in air duct, and air duct has left part intake grill, air duct is taken over and is connected mutually with right ventilation duct by pipeline, and left ventilation duct is taken over and connected mutually with casing;
On the inwall of casing, be adhesively fixed with one deck noise reduction sponge, on noise reduction sponge, form several noise reduction recesses.
Described wind wheel is cross flow blower impeller, wind wheel is comprised of blade, wheel disc and rotor shaft, two ends of blade are separately fixed on wheel disc, the rotating shaft of rotor shaft and motor is fixed together, rotor shaft is fixed on wheel disc, blade is arc sheet, and blade is that width becomes large shape gradually from the bottom to top.
Described air duct is cylindrical tube, and noise reduction recess is spherical cambered surface shape recess.
The beneficial effects of the utility model are:
Its noise is little, in pipeline, blows evenly, can not cause pipeline and because of uneven air, produce sound.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of wind wheel;
Fig. 3 is the structural representation of noise reduction sponge;
Fig. 4 is the structural representation of blade;
Fig. 5 is the A of Fig. 4---A sectional view.
In figure: 1, motor; 2, casing; 3, left ventilation duct is taken over; 4, right ventilation duct is taken over; 5, air duct support; 6, air duct; 61, left part intake grill; 7, wind wheel; 71, blade; 72, wheel disc; 73, rotor shaft; 8, noise reduction sponge; 81, noise reduction recess.
Embodiment:
Embodiment: see shown in Fig. 1,2, quiet tubular indoor ventilator, comprise motor 1, on the left sideboard of casing 2 and right sideboard, be fixed with respectively left ventilation duct adapter 3 and right ventilation duct and take over 4, in casing 2, be fixed with air duct support 5, on air duct support 5, be fixed with air duct 6, motor 1 is fixed on air duct support 5, in the rotating shaft of motor 1, be fixed with wind wheel 7, wind wheel 7 is placed in air duct 6, air duct 6 has left part intake grill 61, and air duct 6 is taken over 4 by pipeline and right ventilation duct and connected mutually, and left ventilation duct is taken over 3 and connected mutually with casing 2;
On the inwall of casing 2, be adhesively fixed with one deck noise reduction sponge 8, on noise reduction sponge 8, form several noise reduction recesses 81.
Described wind wheel 7 is cross flow blower impeller, wind wheel 7 is comprised of blade 71, wheel disc 72 and rotor shaft 73, two ends of blade 71 are separately fixed on wheel disc 72, rotor shaft 73 is fixed on wheel disc 72, rotor shaft 73 is fixed together with the rotating shaft of motor 1, blade 71 is arc sheet, and blade 71 is that width becomes large shape gradually from the bottom to top.
Described air duct 6 is cylindrical tube, and noise reduction recess 81 is spherical cambered surface shape recess.
Working principle: during use, left ventilation duct adapter 3 and right ventilation duct are taken over 4 and connect respectively outdoor air intake pipe and indoor ajutage, takes over the outdoor wind of coming in 3 from left ventilation duct and sends into right ventilation duct adapter 4 through wind wheel 7, thereby enter indoor.
On inwall due to casing 2, be adhesively fixed with one deck noise reduction sponge 8, on noise reduction sponge 8, form several noise reduction recesses 81.Noise when noise reduction recess 81 can cancellation wind flows in casing 2, so its noise is little.
Because motor 1 is fixed in casing 2, motor 1 has accounted for certain spatial position, left ventilation duct adapter 3 and right ventilation duct adapter 4 are just in time separately positioned on the position of left sideboard and right sideboard center, the relatively left ventilation duct adapter 3 of blade 71 and right ventilation duct take over 4 like this, there is deviation the position, middle of the position of blade 71 middles and ventilation duct adapter 3, it is on the high side that blade 71 is positioned at the part on left ventilation nozzle 3 shaft axis tops, so blade 71 is from the bottom to top for width gradually becomes large shape.Can allow like this wind taken over 4 out from right ventilation duct softer evenly.
