Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
Air intake wind-tunnel blast device in a kind of, using as blast device on the products such as air-conditioning, humidifier, air cleaner, stand fan, the vane 3 that it comprises wind-tunnel 2 and is arranged in wind-tunnel.
Different with the existing construction of wind tunnel without blade fan, intake grill 5 is arranged on the inwall of wind-tunnel 2 by it, the cross section of described intake grill 5 is domatic or multi-step face, thus the entrance of wind-tunnel 2 is larger, and outlet is less, after air enters wind-tunnel 2, the air near wind-tunnel inwall is drawn in wind-tunnel inner chamber by intake grill 5, and is entered in main frame 1 by the air intake pipe 4 be connected with wind-tunnel inner chamber.
Described main frame comprises refrigerator, the heating device of air-conditioning, humidifier, air cleaner etc., (said structure is same as the prior art), through driving finally by the high-speed motor be arranged in main frame and impeller (omitting in figure) accordingly, forms high pressure draught, vane 3 is got back to by ajutage 6, and realize air-out by the high pressure exhaust outlet being arranged on vane side in the inside of wind-tunnel, and then drive the air flowing in wind-tunnel, form stable wind-force.High pressure outlet air mouth on described vane is slot-shaped structure or is uniform porous structure.
The curvilinear structures that the shape of described vane is circle, polygonal, heart, the head and the tail such as quincunx are closed, wind Ring current distribution be empty.This cavity can allow air in most wind-tunnel through this cavity, and at high pressure exhaust outlet, place forms suitable wind-force.
Advantage intake grill being arranged on wind turbine apparatus is, it can effectively utilize the suction of intake grill, improves the air draught ability of wind-tunnel, increases the air flowing of wind turbine apparatus.Fig. 1 and Fig. 2 is embodiment one, and its wind-tunnel inwall is domatic, and the suction port on domatic is the staggered slot-shaped structure of multiple tracks or porous structure, is that to reduce dust inhalation device inner, suction port increases filter screen and is necessary.
Directly blow to from the high speed air outlet of vane the suction port be arranged on wind-tunnel inwall for preventing high speed winds, reduce air-out efficiency, the size of vane is less than wind-tunnel inwall, and the external diameter of vane and the ratio of wind-tunnel internal diameter are proper between 2/1 to three/2nds.
Fig. 3 is the construction of wind tunnel of embodiment two, and its wind-tunnel 2 inwall is hierarchic structure, and in step structure, be provided with multilayer intake grill 5.
Due to the electrical equipment that this exhaust apparatus is fixed for external structures such as air-conditionings, therefore can not realize wind-tunnel left-right rotation as electric fan, as air-conditioning, air supply direction can not be changed by shutter.The utility model changes the air supply direction of wind-tunnel entirety by the wind direction changing vane.As shown in Figure 3, embodiment two has installed gear and rotating shaft 8 additional on the ajutage of vane, this gear with horizontally rotate motor 7 and be connected.Horizontally rotating motor drives ajutage 4 to rotate, and realizes left and right and sweeps wind.
For increasing the function of exhaust apparatus further, the utility model also discloses a kind of mechanism allowing vane to rotate up and down, it comprises the ball valve be arranged on bottom vane, vane is connected by ball valve 9 with ajutage, ball valve is provided with gear, the luffing angle of vane can be regulated manually in small angle, and then change the air supply direction of exhaust apparatus.
Because vane size is less, vane directly installs additional the motor changing luffing angle and understands air-out effect by affecting wind, and unsightly also dangerous.As shown in Figure 4, the ball valve 9 of the utility model between vane and ajutage is connected with moving runner 10, this moving runner is connected with the vertical rotation motor (figure does not draw) be arranged on below suction tude by driving belt, this vertical rotation motor drives the moving runner 10 of ball valve 9 inside to rotate by driving belt 11, and then vane realizes sweeping wind up and down.
Vertical rotation motor (figure does not draw) can be hidden in the below of wind-tunnel by this structure, and the protecting jacket of driving belt ajutage protects, and does not expose; therefore Security is better; elegant in appearance, also decrease taking the cross section of wind-tunnel as far as possible, ensure that maximum air-supply efficiency.
Owing to horizontally rotating motor and vertical rotation motor is Electronic control, the automatic control that control circuit and program therefore can be adopted easily to realize left and right sweep wind and sweep wind up and down, the wind direction of increase exhaust apparatus.It is also applicable to installing remote device, further facilitates user and uses.
