Description of reference numerals: 10, whirlpool tongue; 21, the first side wall; 22, curved wall; 23, the second sidewall; 31, fan blade spatial accommodation; 40, air channel; 50, air outlet.
Detailed description of the invention
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
As shown in Figure 1, according to embodiments of the invention, volute comprises volute sidewall and whirlpool tongue 10, whirlpool tongue 10 is fixedly installed on volute sidewall, volute sidewall comprises the first side wall 21, the first side wall 21 and whirlpool tongue 10 are oppositely arranged, and be diffusion district between whirlpool tongue 10 and the first side wall 21, the minimum widith in diffusion district is in the scope of 205mm to 220mm.Wherein, the minimum widith in diffusion district refers to that in Fig. 1, the point near the first side wall 21 of whirlpool tongue 10 arrives the distance of the first side wall 21 in the horizontal direction, it should be noted that this horizontal direction is the horizontal direction in Fig. 1.The minimum widith in diffusion district is in the scope of 205mm to 220mm, and can reduce wind speed when ensureing air quantity, and then reduce noise, make the noise of volute less, Consumer's Experience is better.
In the present embodiment, volute sidewall also comprises curved wall 22 and the second sidewall 23, and curved wall 22 is connected between the first end of the first side wall 21 and whirlpool tongue 10, and curved wall 22 and whirlpool tongue 10 surround fan blade spatial accommodation 31.Curved wall 22 effectively by the air intake rectification of volute, and then can reduce the noise of volute.Second sidewall 23 is connected with the second end of whirlpool tongue 10, and the first side wall 21, second sidewall 23, curved wall 22 and whirlpool tongue 10 surround air channel 40.Volute is provided with air outlet 50 away from the side of curved wall 22, and air channel 40 is communicated with air outlet 50.
Air channel 40 comprises diffuser, and diffusion district also belongs to air channel 40, and diffusion district is connected with diffuser, and along the direction near air outlet 50, the width of diffuser increases gradually.Diffuser can reduce wind speed effectively, and then reduces noise, can also ensure air output simultaneously.In the present embodiment, along the direction near air outlet 50, the second sidewall 23 extends to the direction gradually away from the first side wall 21, and such the first side wall 21 and the second sidewall 23 form this diffuser, significantly reduce noise, improve comfort level when user uses.
Preferably, the minimum widith in diffusion district is 215mm.Volute can be made like this to increase air output, reduce wind speed, to reduce noise simultaneously.In use, can obtain equal air quantity under the rotating speed that motor is less, this point can reduce level of noise when motor runs up.
In the present embodiment, whirlpool tongue 10 is protruding towards the first side wall 21, and whirlpool tongue 10 is 20mm towards the radius of the convex globoidal of the first side wall 21.Effectively can optimize the flow field of the wind in volute like this, the turbulent flow or eddy current avoiding profile to suddenly change causing, and then reduce noise, improve comfort level when using.
According to a further aspect in the invention, air-conditioner comprises volute, fan blade and motor, and this volute is above-mentioned volute, and fan blade is arranged in the fan blade spatial accommodation 31 of volute, and motor is connected with fan blade and drives fan blade to rotate.
Preferably, the minimum range between the first end of whirlpool tongue 10 and the outward flange of fan blade is 28.2mm.Air-flow effectively can be avoided like this to occur return air problem, and then avoid the generation of turbulent flow and eddy current, and reduce noise, improve comfortableness when using.
Following table is the experimental data of each wind shelves noise test of volute in embodiments of the invention:
Volute in embodiments of the invention shows that in test process each wind shelves noise when ensureing air output all decreases.
From above description, can find out, the above embodiments of the present invention achieve following technique effect: when motor and fan blade are determined, the parameter of motor and fan blade is all constant, can make motor under lower rotating speed, obtain the air output meeting user demand by the distance increased between whirlpool tongue and the first side wall, and then the noise avoiding motor High Rotation Speed to produce, gap simultaneously between whirlpool tongue and fan blade increases can avoid wind to reflux effectively, and then reduces the noise because turbulent flow and eddy current produce.
These are only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
