Abstract
The utility model relates to a lateral flow air exhausting device. A first cross flow fan is installed at an air inlet side of an air chamber of the utility model, and a second cross flow fan installed at an air outlet side of the air chamber of the utility model, a stator is arranged between the two cross flow fans to destroy partial flow field and to form a consistent ventilation flow field passageway, and air suction area of the air inlet side can be increased. The running noise of the utility model can be reduced, and the utility model is suitable for the implementation of a kitchen ventilator.
Description
The utility model is about a kind of venting gas appliance, particularly uses the venting gas appliance of cross flow fan.
Venting gas appliance is widely used in the space of closed shape, and as factory building, kitchen etc., the most normal application is lampblack exhauster in the kitchen.
The performance requirement of venting gas appliance is that it has bigger air draught area, and the high running noise of inlet air side negative pressure is low or the like.With the lampblack exhauster is example, and the design of increasing suction force is very many, announces patent No. 279496 just like Taiwan, and it has been used two groups of motors of two groups of motors in top and oblique side and has strengthened suction, and attempt increases the air draught area.
In any case but up to now, lampblack exhauster all is to utilize centrifugal exhausting, air-flow is after being sucked by central hole, borrow centrifugal force to extrude the air side, so the air draught area to be difficult to enlarge; And it uses centrifugal flow and then must just can prove effective by high speed rotating, so the noise of running promptly can't reduce.If utilize many induced draft fans to fit together, perhaps the intensity of draft can improve, but cost power consumption and noise all will increase thereupon.
The purpose of this utility model is to provide a kind of venting gas appliance, and its air draught area can significantly increase, even can axially widen.
The purpose of the utility model further is to provide a kind of venting gas appliance, though it has used two groups of its noise in operating of ventilating fan extremely low.
A purpose again of this case is to provide the venting gas appliance of a kind of oil supply and discharge cigarette machine use, and its cost is low, power consumption is few, noise is low, but air draught area and air draught usefulness can increase.
Realize the utility model purpose, be to be in the air compartment of venting gas appliance, one first cross flow fan and second cross flow fan in the air side that is installed in the inlet air side arranged, and between this two cross flow fan, be provided with a stator to destroy local flow field and to form consistent exhausting flow field channel, inlet air side draught wind area is increased, but the running noise of venting gas appliance can reduce.The inlet air side of the utility model can become the wind-collection cover of lampblack exhauster or other air draughts or collection pressure equipment by the air compartment wind-collection cover that stretches out.
Major advantage of the present utility model is:
1. the air draught area can significantly increase, even can axially widen;
2. noise in operating is extremely low;
3. cost is low, power consumption is few.
Now the embodiment with accompanying drawing illustrates feature of the present utility model and effect.
Fig. 1 is that the utility model crossing current is pumped formula venting gas appliance embodiment's sectional view;
Fig. 2 is the schematic side view of cross flow fan among Fig. 1;
Fig. 3 is the sectional view that the device of Fig. 1 is applied to lampblack exhauster embodiment.

The 21--first cross flow fan 22--second cross flow fan
23--flabellum 24--side ring sheet 25--actuator
31--stator 32--blade 41--wind-collection cover
As Fig. 1, shown in Figure 3, in the air compartment 11 of the utility model venting gas appliance foundation, an inlet air side 12 and an air side 13 are arranged, between inlet air side 12 and air side 13, be the exhausting flow field channel of the utility model venting gas appliance.
There is one first cross flow fan 21 to be installed in inlet air side 12 in the air compartment 11; Another second cross flow fan 22 is installed in the air side 13 in the air compartment 11; And there is a stator 31 to be installed between this first and second cross flow fan, the wind speed of air compartment 11 middle sections is reduced and the blast rising.
The cross flow fan 21 or 22 of the utility model application, as shown in Figure 2, be different from and practise the centrifugal fan that has, it has most radiation-like and is distributed in flabellum 23 on the same radius, the two ends of these flabellums 23 are solid respectively at side ring sheet 24, this side ring sheet 24 axle of ining succession is subjected to actuator 25, is motor or belt pulley etc. for example, drives and rotates.Among this cross flow fan the centre be empty, air-flow as shown in Figure 1, pass its central authorities and to the air side runner.Cross flow fan existing at present people be applied on the blast device of the indoor set in the separate cold machine, it mainly is to utilize the change of inlet air side and air side blast and the natural convection that causes air-flow, so its flabellum rotating speed is slow, noise is little but the air draft effect is very desirable.
The utility model increases the area of inlet air side 12, can make that flow field in the cross flow fan is uneven to be increased and improve its efficient, and two cross flow fans can increase usefulness each other after how contacting, and as detailed ripe this skill person, is the thing of difficulty very.
The utility model is installed two rectification fans 21,22 in air compartment 11, be a kind of embodiment, can make plural cross flow fan polyphone if use the technology of the utility model in fact, all can reach the effect of gain.Each cross flow fan can be driven by the different belt pulleys that are subjected to same motor driven individually, and fabricating cost and running noise all can be reduced.The utility model is in particular in air compartment 11, one stator of being made up of every air blade 32 majority 31 is set between per two cross flow fans, make the local flow field of destroying between two cross flow fans, make first cross flow fan 21 or second cross flow fan 22 all can respectively obtain the imbalance in flow field, both sides, and cause flowing naturally of air-flow, integrate, but constitute a consistent exhausting flow field channel.Aforementioned blade 3 preferably can be arcuation along the curved shape of air compartment 11.
As shown in Figure 3, the utility model can make first cross flow fan 21 be contained in side under second cross flow fan 22 if be applied to lampblack exhauster, and extends a wind-collection cover 41 by inlet air side 12 and strengthen air-breathing effect outside air compartment 11.
