Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Present invention seek to address that air duct noise abnormal problem caused by being limited because of shell dimension, proposes a kind of through-flow air duct
Structure, including spiral case, panel, air inlet and outlet are provided with through-flow fan blade, the panel and the through-flow in the spiral case
The space that unequal spacing is formed between fan blade, the minimum spacing between the panel and through-flow fan blade is L, in the positions of panels
It is provided with air guide structure.Through-flow air channel structure of the invention can be adapted in warm-air drier and air conditioner.
The present invention promotes volute tongue to go out stream and mentions by using special air guide structure in through-flow fan blade and panel minimum gap location
Before return to through-flow area, to achieve the purpose that mention effect noise reduction.
Embodiment one
The present embodiment is further described through-flow air channel structure by taking warm-air drier as an example.
The structure of the warm-air drier is as shown in Figure 1, primary structure includes air inlet 1 and air-inlet grille, panel 2, through-flow fan blade
3, air guide structure 4, volute tongue 5, heat exchange equipment 6, air outlet 7, spiral case 8, snail larynx 9 etc..Wherein: air inlet 1 and air-inlet grille, it is described
Air inlet 1 is placed in air inlet 1 in warm-air drier upper end, the air-inlet grille, and air-inlet grille has the function of preventing scald；Panel
2, the panel 2 is unilateral in air inlet 1 and air-inlet grille lower part, after warm-air drier installs, 2 face client of panel；Through-flow wind
Leaf 3, the through-flow fan blade 3 are high speed rotary motion component inside warm-air drier；Air guide structure 4 is set to 2 position of panel；It passes through
5 structure of volute tongue in air duct is flowed, 5 structure of volute tongue in the through-flow air duct is between heat exchange equipment 6 and the through-flow fan blade 3, with
The through-flow fan blade 3 is in a fixed spacing；Heat exchange equipment 6, the heat exchange equipment 6 are the heat-producing device in warm-air drier, are passed through described
Flow the downstream of fan blade 3；Air outlet 7, the air outlet 7 is in 6 downside of cross flow fan and the heat exchange equipment, close to panel 2, institute
Belong to air outlet 7 to include and be not limited to the structures such as air outlet grate, guide vane, wind deflector；8 structure of spiral case, 8 structure of spiral case is described
The through-flow fan blade 3, the spiral case 8 and the volute tongue 5 are wrapped up in the left and right sides with the panel 2 in the other side of through-flow fan blade 3
Together with the panel 2, the through-flow air duct of warm-air drier is formed with the through-flow fan blade 3；9 structure of snail larynx, 9 structure of snail larynx exist
Between the spiral case 8 and the air inlet 1, it is connected with the upstream of 8 structure of spiral case.
As a kind of alternative solution of air guide structure, the air guide structure 4 is bending plate, and one end of which is fixed on the faces
On plate 2, other end suspension.The entirety that the air guide structure 4 is preferably set as shown in Figure 1 is upwarped in arcuation, the side upwarped
It is identical to the circumferential speed vector rotated with the through-flow fan blade blade nearest apart from the position.
As a kind of alternative solution of air guide structure, the air guide structure 4 is straight panel structure as shown in Figure 7, one end
It is fixed on the panel 2, other end suspension.
When air guide structure is straight panel or bending plate, the setting of air guide structure meets the following conditions:
Wherein, DminIndicate the minimum clearance between through-flow fan blade 3 and panel 2；The horizontal length of d expression air guide structure.
When air guide structure be straight panel or bending plate when, it is preferable that the air guide structure can be set it is multiple, that is, use 2
To the air guide structure of n identical or different length, identical or different spacing.The present embodiment is with three equidistant air guide structures
Example is illustrated.As a kind of alternative solution of air guide structure, the arrangement of multiple air guide structures is as shown in figure 5, edge
Close to 7 side of air outlet panel 2 on successively arrange, wherein first air guide structure is set between panel 2 and through-flow fan blade 3
Minimum spacing at.In that case it is preferable that each air guide structure suspension end and 3 rotation center of through-flow fan blade away from
From identical, which can preferably promote the air-out volume of cross flow fan, more effectively improve blower integrally mute performance.
As a kind of alternative solution of air guide structure, the air guide structure is as shown in fig. 6, set court for the panel 2
To the arcuate structure of through-flow air duct internal protrusion.
As a kind of alternative solution of air guide structure, the air guide structure can also be the knot as shown in scheme 1 in Fig. 3
Structure, that is, 2 position of panel is pushed outward, the minimum clearance between panel 2 and through-flow fan blade 3 is made to be greater than L.This scheme
The advantages of be: since the position of panel 2 is pushed outward, the distance between through-flow fan blade 3 increase, to reduce due to face
Plate 2 and through-flow fan blade 3 it is too close and caused by interfere, so as to effectively reduce noise.But this scheme can be into one
The current leakage phenomenon of step aggravation volute tongue position.Therefore, this programme be mainly used for verify noise Producing reason whether with panel and wind
The distance between leaf is related.
In order to control fan noise, cross flow fan volute tongue needs to keep certain distance with fan blade, but the gap is also leakage current
Main positions, high-speed flow from volute tongue gap leak out after, return to panel zone, since panel is closer from fan blade, high-speed flow
It interacts with panel and generates abnormal sound.By increasing local flow-guiding structure at through-flow fan blade and panel minimum clearance, although seeing
Panel and fan blade gap are seemingly further shortened, but since the section of flow-guiding structure is small, souring limited area is led simultaneously
Flow structure by volute tongue leakage current again Bi Hui through-flow area, reduce volute tongue leakage current flow and eccentric vortex size (specific visible Fig. 3 and under
Table), simulation result shows to increase the part flow-guiding structure, and flow enhancement 17%, Kuanping Terrane is declined.
Each scheme based on Fig. 3 emulates data statistic
| Air quantity (m3/h) | Kuanping Terrane value (dB) | |
| Former scheme | 152 | 96.9 |
| Scheme 1 | 181 | 89.7 |
| Scheme 2 | 137 | 84.6 |
| Scheme 3 | 169 | 85.1 |
| Scheme 4 | 178 | 86.4 |
| Scheme 5 | 152 | 81.3 |
Wherein: scheme 1 is to push 2 position of panel outward；Scheme 2 is directed towards the arc of through-flow air duct internal protrusion
Structure；Scheme 3 is that shorter straight panel is arranged at minimum clearance between through-flow fan blade 3 and panel 2；Scheme 4 is in through-flow wind
Longer straight panel is set at the minimum clearance between leaf 3 and panel 2；Scheme 5 is the minimum between through-flow fan blade 3 and panel 2
Straight panel is arranged in the top of gap location.
In conclusion the present invention increases air ducting by part, promotes through-flow air duct volute tongue to go out and flow in place mention
Preceding return through-flow area has achieved the purpose that propose effect to improve the air quantity of cross flow fan；By allowing the high speed gas of volute tongue position
It flows to end and reenters through-flow area fastly, reduce the action time of the position high-speed flow and panel, utmostly reduce because sound is dry
Noise caused by relating to is abnormal.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention.It is all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
