The minimum 0.5L2 of nozzle opening width that flow control valve piece 13 in fresh air runner 4 is formed, implies that the stream in fresh air runner 4
Road controls the half that 13 nozzle opening width minimum of valve block can be fresh air runner 4, and the flow control valve piece 13 in return air runner 5
Nozzle opening width minimum can also be controlled to the half of fresh air runner 4, and the size of jet hole can be according to the fresh air of indoor demand
Amount is adjusted, generally under 22 starting state of centrifugal blower of new wind turbine, the runner control in fresh air runner 4 and return air runner 5
Valve block 13 processed is fully open state, i.e. flow control valve piece 13 is adjacent to runner side wall completely, when the centrifugal blower in new wind turbine
It in the case that 22 is inoperative, and needs to reach indoor cross-ventilation, you can the flow control valve piece 13 in control fresh air runner 4
It inwardly reduces and forms jet hole so that the gas flow rate for flowing through jet hole is accelerated, while can control fresh air valve block 11 or return air
Valve block 12 rotate to 90 degree, thereby by aerodynamics nature drive gas flow move, make room air centrifugal blower 22 not
It can still provide for the flowing of air in the case of operating.
It please refers to Fig.4 in both of the aforesaid embodiment, the valve block edge of fresh air valve block 11 and return air valve block 12 is equipped with close
Sealing piece 14,14 material of sealed film are wearable elastic resin, such as can be the polyurethane material films after solidification, and setting exists
The edge of fresh air valve block 11 and return air valve block 12 and with flow path wall be fitted close or or interference fit, avoid vertically sealing in valve block
Gas leakage is generated under closed state, the film of polyurethane material has the advantages that wear-resisting, resistance to deformation, waterproof and elasticity are good.
In addition, being additionally provided with cleaning module in the downstream of coaxial incorgruous valve block 9, cleaning module includes sequentially electrostatic charging area
15, the high efficiency particulate air filter 18 in electrostatic precipitation area 16, ozone sterilization area 17 and physical filtering form, while in order to effectively filter
Indoor formaldehyde is also provided with purifying formaldehyde module 19 in return air runner 5.
Embodiment 3
In addition, the invention also provides a kind of control methods of house air purification fresh air blower：Include the following steps：1)
Gas concentration lwevel, PM2.5 concentration and concentration of formaldehyde in sensing space；2) dense according to the gas concentration lwevel, PM2.5 that are sensed
Degree and concentration of formaldehyde adjust coaxial 9 rotation angle of incorgruous valve block, and coaxial incorgruous valve block 9 includes fresh air valve block 11, return air valve block
12 and axle center 10, fresh air valve block 11 is set to the both ends in axle center 10 with return air valve block 12, fresh air valve block 11 and return air valve block 12 it
Between there is angle theta, return air width of flow path to be L1, fresh air width of flow path is L2, and relationship between L1, L2 and θ is sin θ=1-
(L2/L1), when gas concentration lwevel, PM2.5 concentration and concentration of formaldehyde are below preset value, returning in coaxial incorgruous valve block 9
Air valve piece 12 is rotated to upright position；3) flow control valve piece 13 is set on the flow path wall of return air runner 5 and fresh air runner 4,
It is tightened from flow path wall to runner center, makes that tapered nozzle is presented along gas flow direction in return air runner 5 or fresh air runner 4
Shape, when gas concentration lwevel, PM2.5 concentration and concentration of formaldehyde are below preset value, the runner control in adjustment fresh air runner 4
Valve block 13 is adjusted to 1/2 that jet hole openings of sizes is return air runner 5.
When gas concentration lwevel, PM2.5 concentration and concentration of formaldehyde are below preset value, Interior Space gas phase at that time is indicated
To clean, therefore centrifugal blower 22 implies that the ventilation for not forcing to carry out room air without operating in most of new wind turbine,
The indoor occupant that gets off for a long time is easy to feel unhappy, in addition, persistently starting in the room air for having had relative clean
Centrifugal blower 22 not only generates running noise, while also expending electric power, therefore utilizes house air purification proposed by the present invention
The control method of new wind turbine does not start centrifugal blower 22, but adjusts in fresh air runner 4 under the air conditions of relative clean
The jet hole size of flow control valve piece 13 so that accelerated by the wind speed of jet hole size, with aerodynamic principle
So that room air is carried out microcirculation, achievees the effect that not consume energy while gas Natural Circulation.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
