The utility model proposes a kind of air-conditioning internal machine, referring to Fig. 1, the air-conditioning internal machine 100 includes air channel structure, it is described Air channel structure includes snail tongue 10, and Fig. 2 to Fig. 3 is an embodiment of snail tongue 10 provided by the utility model.

Fig. 2 and Fig. 3 are referred to, to form the air channel 20 of air-conditioning internal machine 100, the snail tongue 10 includes interior the snail tongue 10 Side plate 1, outer panel 2 and absorbent treatment 3, the interior plate 1 are set to form the snail tongue towards the air channel 20 and in bending 10 outline, the interior plate 1 are provided with perforation 4, and the outer panel 2 is back to the air channel 20, and with the two of the interior plate 1 End connection, so that the interior plate 1 encloses to form accommodating chamber jointly, the filling of absorbent treatment 3 is located in the accommodating chamber, and by Sound-absorbing material is made.

In technical scheme provided by the utility model, the inside of snail tongue 10 of air-conditioning internal machine 100 is provided with accommodating chamber, the receiving Intracavitary is provided with absorbent treatment 3 made of sound-absorbing material, and the interior plate 1 of the snail tongue 10 is provided with and the accommodating chamber identical perforation 4, in this way, the sound wave of noise caused by the tubular wine wheel 30 of the air-conditioning internal machine 100, can be by described in the perforation 4 entrance Accommodating chamber, given and absorb by the absorbent treatment 3, so that lower noise, also, relative to spiral case in the air-conditioning internal machine 100 etc. Other positions set absorbent treatment, by setting the absorbent treatment 3 in the snail tongue 10, to the appearance and size of the tubular wine wheel 30 Can be especially suitable without modification, therefore to requiring not change the air-conditioning internal machine 100 of the appearance and size of tubular wine wheel 30.

The sound wave of noise is the inside for entering the snail tongue 10 by the perforation 4, is absorbed by the absorbent treatment 3, Therefore the perforation 4 sets how much with the quality of acoustically effective have certain relation, and in view of the perforation 4 to the snail tongue 10 The influence of bulk strength, set the excessive perforation 4 to reduce the intensity of the snail tongue 10, shorten the use of the snail tongue 10 In the life-span, after considering factors above, in the present embodiment, the punching rate of the interior plate 1 is 0.08~0.2, is so set Put, that is, ensure that the acoustically effective of the snail tongue 10, do not interfere with the service life of the snail tongue 10 again.

Equally, the diameter of the perforation 4 can also impact to the acoustically effective of snail tongue 10, consider at the same time The acoustically effective of the snail tongue 10, and processing technology and production cost in view of the perforation 4, in the present embodiment, institute State a diameter of 1mm~3mm of perforation 4.

Further, in the present embodiment, the pitch of holes of adjacent two perforations 4 is 3mm~5mm.

The interior plate 1 of the snail tongue 10 is the internal face for forming the air channel 20, and wheel blower fan 30 institute is passed through in order to described Caused air-flow can at the pot tongue 10 gentle transition, avoid produce noise, in the present embodiment, the interior plate 1 includes Form the bent intermediate section 11 of the contouring head of the snail tongue 10 and correspondingly extend from the both ends of the bent intermediate section 11 The first extension 12 and the second extension 13, wherein, when the snail tongue 10 is attached in the air channel 20, described second prolongs Air outlet 40 of the section 13 close to the air channel 20 is stretched to set.It is arranged such, moreover it is possible to increase described 11 pairs of noises of bent intermediate section Receiving area, further improve the acoustically effective of the snail tongue 10.

In order to increase receiving area of the snail tongue 10 to noise, while the snail tongue 10 considered is to the air-conditioning internal machine The influence of 100 air outputs, referring to Fig. 3, in the present embodiment, the folder between the extension 13 of the first extension 12 and second Angle is α, and 50 °≤α≤70 °.

The snail tongue 10 is to carry out the sound wave of absorption of noise by the absorbent treatment 3 made of sound-absorbing material, therefore the sound absorption The acoustic absorptivity size of material directly influences the acoustically effective of the snail tongue 10, while takes into account production cost, material The factor such as stability and use environment, in the present embodiment, the sound-absorbing material be centrifugally glass-wool, rock wool, mineral wool or String.

It is influential on the air-out effect of the air-conditioning internal machine 100 that the set location of the snail tongue 10, which is, is considered simultaneously To the acoustically effective of the snail tongue 10, referring to Fig. 1, in the present embodiment, the snail tongue 10 is located at the air-conditioning internal machine 100 The angle between the spiral case air-out wall of chassis 50 of air outlet 40, second extension 13 and the air channel structure is β, And 15 °≤β≤25 °.

Equally, the distance between the tubular wine wheel 30 and the snail tongue 10, also can be to the acoustically effective of the snail tongue 10 Have an impact, in the present embodiment, the minimum clearance between the tubular wine wheel 30 and snail tongue 10 is 4mm~6mm, in this area Between, the acoustically effective of the snail tongue 10 is optimal.

Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, Every equivalent structure change under inventive concept of the present utility model, made using the utility model specification and accompanying drawing content Change, or directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
