Detailed description of the invention

Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 1, Fig. 1 is the sectional view of a kind of air conditioner room unit of the utility model preferred embodiment.This air conditioner room unit is specially a kind of indoor machine, and it comprises housing, is arranged on the evaporimeter 5 in housing and spiral case 6, and be arranged on the centrifugal wind wheel 1 in spiral case 6, air-ducting ring 2, centrifugal wind wheel 1 has multiple blade, housing is provided with air inlet 3 and air outlet 4; Air-ducting ring 2 can be fixedly connected with centrifugal wind wheel 1 by the mode such as buckle or screw.

Wherein, namely spiral case 6, centrifugal wind wheel 1 and air-ducting ring 2 form the air ducting of the utility model one embodiment, shown in composition graphs 2 and Fig. 3, in the present embodiment, described air-ducting ring 2 is arranged on air inlet 3 place of described centrifugal wind wheel 1, and described air-ducting ring 2 is provided with multiple projection 21 for rectification.

Thus, by arranging multiple projection 21 for rectification in air-ducting ring 2, the air-flow entering centrifugal wind wheel 1 can be guided to carry out rectification, air-flow is made to become more smooth and easy, and reduce the quantity in whirlpool in air-flow and weaken the intensity in whirlpool, thus the energy loss caused when reducing turbo-charger set, improve the efficiency of centrifugal wind wheel 1, and reduce noise.

Particularly, preferably, the quantity of protruding 21 can be 10-100.

As a kind of embodiment, above-mentioned multiple protruding 21 evenly can be arranged along the periphery of described air-ducting ring 2, as shown in Fig. 2, Fig. 3 and Fig. 5, can guide the air-flow rectification better entering centrifugal wind wheel 1 like this.In the present embodiment, described protruding 21 inner surfaces being arranged on described air-ducting ring 2, as shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, to strengthen protruding 21 to the rectification effect of air-flow entering centrifugal wind wheel 1.

Preferably, described air-ducting ring 2 can integrated injection molding with protruding 21, which not only adds the intensity of protruding 21, also makes the manufacturing of protruding 21 simpler.

The present embodiment is not construed as limiting, particularly, as a kind of embodiment the shape of protruding 21, described protruding 21 can be straight flange strip, as shown in Fig. 5, Fig. 6 and Fig. 7, the air-flow entering centrifugal wind wheel 1 better can be guided like this to carry out rectification, make air-flow become more smooth and easy.

As a kind of embodiment, described protruding 21 vertically can be arranged at the inner surface of described air-ducting ring 2, as shown in Figures 5 and 6, namely roughly survey direction setting along the axle of air-ducting ring 2.

As another kind of embodiment, described protruding 21 also can be obliquely installed along the inner surface of described air-ducting ring 2, as shown in Figure 7.Wherein, tilt angle alpha=90 of protruding 21 ° ± 45 °, than 90 as shown in Figure 6 °, are less than 90 ° shown in Fig. 7.

The present embodiment passes through such scheme, especially by arranging multiple projection 21 for rectification in air-ducting ring 2, the air-flow entering centrifugal wind wheel 1 can be guided to carry out rectification, air-flow is made to become more smooth and easy, and reduce the quantity in whirlpool in air-flow and weaken the intensity in whirlpool, thus the energy loss caused when reducing turbo-charger set, improve the efficiency of centrifugal wind wheel 1, and reduce noise.

Compared to existing technology, the air-ducting ring 2 that the utility model provides, not only has advantages of simple, be easy to the advantage of processing, and its noise reduction is obvious, applied widely, embody the design concept that enterprise product is optimized better, also can promote the experience of user simultaneously.

The air-conditioner that the utility model proposes, can comprise the air ducting described in above-described embodiment, not repeat them here.

When same air quantity, the air-conditioner of the utility model embodiment air ducting is adopted about to reduce by 0.3 ~ 0.5dB than the noise of the air-conditioner of the air-ducting ring 2 in existing correlation technique.

The utility model embodiment air ducting and there is the air-conditioner of this air ducting, by arranging multiple projection 21 for rectification in air-ducting ring 2, the air-flow entering centrifugal wind wheel 1 can be guided to carry out rectification, air-flow is made to become more smooth and easy, and reduce the quantity in whirlpool in air-flow and weaken the intensity in whirlpool, thus the energy loss caused when reducing turbo-charger set, improve the efficiency of centrifugal wind wheel 1, and reduce noise.The air-ducting ring 2 that the utility model provides, not only has advantages of simple, is easy to the advantage of processing, and its noise reduction is obvious, applied widely, embodies the design concept that enterprise product is optimized better, also can promote the experience of user simultaneously.

The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
