Embodiment
Core of the present invention is to provide the assembly of a kind of centrifugation blade and spiral case, to reduce eddy current crack, improves air quantity and efficiency.Present invention also offers a kind of centrifugation blade and indoor apparatus of air conditioner.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is the structural representation of the assembly of centrifugation blade provided by the present invention and spiral case; Fig. 2 is the structural representation of centrifugation blade provided by the present invention; Fig. 3 is the close-up schematic view of part A in Fig. 2.
In this embodiment, the assembly of centrifugation blade and spiral case comprises centrifugation blade and spiral case 3.Wherein, the blade 2 of centrifugation blade is provided with chamfering 21 towards the end of the side at the center of centrifugation blade; Spiral case 3 has the baffle liner 4 extended to spiral case 3 inside; In the space that the chamfering 21 that baffle liner 4 stretches into blade 2 towards one end of spiral case 3 inside is vacated.
The assembly of the centrifugation blade that the embodiment of the present invention provides and spiral case, by arranging chamfering 21 in the end of blade 2, the end avoiding blade 2 makes air-flow increase situation because of corner structure, and then reduce the voorticity of this position.In the space that the blade 2 that the baffle liner 4 of spiral case 3 extend into centrifugation blade towards one end of spiral case 3 inside produces because arranging chamfering 21, making the end of blade 2 overlapping with one end of baffle liner 4, reducing the region of eddy current.By above-mentioned setting, reduce the voorticity of the end of blade 2, and, reduce the region of eddy current, and then significantly reduce eddy current crack, and, improve air quantity and the efficiency of blower fan.
In order to improve the stability of strutting system to blade 2 end, reduce noise further, centrifugation blade also comprises the end being arranged at blade 2 and is provided with retainer ring 1.By arranging retainer ring 1, effectively improve the stability of blade 2 end, reducing the vibration of blade 2 end.
Blade 2 is the buckling blade bending towards windward side, and it comprises linkage section 23 and is positioned at the bend section 22 of linkage section 23 towards the side at the center of centrifugation blade.That is, linkage section 23 and bend section 22 joint form bending angle, and blade 2 is bending towards windward side, further increases air output.Wherein, chamfering 21 is positioned on bend section 22.Also chamfering 21 can be arranged at linkage section 23 and bend section 22 place, make chamfering 21 cross over the joint of linkage section 23 and bend section 22.
In the assembly of the centrifugation blade that the embodiment of the present invention provides and spiral case, baffle liner 4 is by the gradually expansion type baffle liner of spiral case 4 externally to its internal direction.Wherein, by spiral case 4 externally to its internal direction and air intake direction.When baffle liner 4 is convergence pattern (horn mouth pattern, contrary with gradually expansion type) structure, suction port dorsal area can produce larger eddy region, causes noise to increase.Therefore, preferably baffle liner 4 is set to gradually expansion type baffle liner, effectively reduces the range size of eddy region.
In order to improve air intake smoothness, the guide face of baffle liner 4 is towards the cambered surface of its center curvature.Also the guide face of baffle liner 4 can be set to plane, that is, baffle liner 4 be set to conical structure.Wherein, the guide face of baffle liner 4 is the inner ring face of baffle liner 4.
As shown in Figure 4, Figure 5 and Figure 6, the one end due to the baffle liner 4 of spiral case needs chamfering 21 position of the blade 2 stretching into centrifugation blade, therefore, needs one end of baffle liner 4 to insert in centrifugation blade.For the ease of assembling, spiral case 3 comprises the first spiral case part 31 and the second spiral case part 32; Baffle liner 4 comprises the first baffle liner part 41 and the second baffle liner part 42, first baffle liner part 41 and is positioned at the first spiral case part 31, second baffle liner part 42 and is positioned in the second spiral case part 32.In installation process, now a volute section in centrifugation blade and the first spiral case part 31 and the second spiral case part 32 is divided and be mounted opposite, again another spiral case part and centrifugation blade are mounted opposite, then pass through the relatively fixing of two spiral case parts, complete the assembling of centrifugation blade and spiral case.
First baffle liner part 41 and the second baffle liner part 42 are semicircle baffle liner.By above-mentioned setting, facilitate the mutual assembling of centrifugation blade and spiral case further.
In the present embodiment, the first spiral case part 31 is connected by buckle 5 with the second spiral case part 32.That is, the first spiral case part 31 and the second spiral case part 32 link together by buckle 5 is dismountable, the convenient maintenance to the component (as centrifugation blade) of spiral case 3 inside and maintenance.
The embodiment of the present invention additionally provides a kind of centrifugation blade, comprises blade 2, and the blade 2 of centrifugation blade is provided with chamfering 21 towards the end of the side at the center of centrifugation blade.By arranging chamfering 21, the end avoiding blade 2 makes air-flow increase situation because of corner structure, and then reduce the voorticity of this position.
The embodiment of the present invention additionally provides a kind of indoor apparatus of air conditioner, comprises the assembly as any one centrifugation blade above-mentioned and spiral case.Because the assembly of above-mentioned centrifugation blade and spiral case has above-mentioned technique effect, there is above-mentioned centrifugation blade and also should have same technique effect with the indoor apparatus of air conditioner of the assembly of spiral case, tire out no longer one by one at this and state.
Above the assembly of centrifugation blade provided by the present invention and spiral case is described in detail.Apply specific case herein to set forth principle of the present invention and mode of execution, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
