The specific embodiment
A kind of as shown in Figure 1, 2, 3 low noise cabinet air conditioner includes:
Air-conditioner cabinet, described air-conditioner cabinet surround described air-conditioner the rear portion, about portion, top and bottom; The and arranged on left and right sides of described air-conditioner cabinet is provided with air intake panel 1, and described air intake panel 1 is provided with air inlet;
Top plate body, plate body combines with the leading flank of cabinet air conditioner cabinet above this, and the top of this top panel is provided with the wind outlet panel 8 that is used for discharging air, and described wind outlet panel 8 is provided with exhaust outlet;
Following plate body, downside of plate body plate body on described combines with described cabinet below this;
The air-supply parts, described air-supply parts are positioned at air-conditioner cabinet inner chamber bottom, the rear side of described following plate body, described air-supply parts are installed on the described air-conditioner cabinet; Described air-supply parts include motor 2, centrifugation blade 3, spiral case 4, electric machine support 6 and installing plate 7;
Wherein, described motor is a kind of dual-gripper external rotor electric machine, and the main body of described motor is positioned at the centre position of air-conditioner cabinet inner chamber bottom, and described motor driving shaft 5 all stretches out both sides to the left and right; Described motor is fixed on the installing plate 7 by the electric machine support 6 that is connected with the diaxon end; Described centrifugation blade is a kind of double-suction centrifugal pump fan blade, and described motor 2 is positioned at described centrifugation blade middle part, and the rotor of described motor is connected by bolted with the metal flange of described centrifugation blade 3; Described spiral case 4 is fixed on the installing plate 7 by tapping screw.
From described cabinet air conditioner front, described air-supply parts are for being the symmetrical structure of center line with the air-conditioner vertical center line.
Described double-suction centrifugal pump fan blade 3 is metalwork or moulding, and the mid-game of moulding fan blade studs with the metal fan blade mold insert 31 of flange-type, and with the fan blade injection mo(u)lding, described fan blade mold insert 31 is connected by bolt with the flange of motor 2.
Two air inlets of described spiral case are corresponding with the air intake panel of the both sides of cabinet air conditioner cabinet respectively.
The mid-game of moulding fan blade studs with the metal inserted piece of flange-type, and with the fan blade injection mo(u)lding, the fan blade mold insert 31 of flange-type is connected by bolt with the flange of motor.Described double-suction centrifugal pump fan blade 3 can also be the metal fan blade, and the blade of metal fan blade and mid-game all are metalwork, and fan blade mid-game flange direct and motor passes through Bolt Connection.
Described fan blade is a double suction forward multiple wing centrifugal fan blade.
The log spiral spiral case that described spiral case 4 is equilateral basic circle methods is connected and fixed with tapping screw and installing plate 7.
Therefore the present invention has increased the incoming air area of blower fan owing to adopt the double-suction centrifugal pump fan blade, makes the air intake flow velocity more even, and size is littler than traditional blower fan simultaneously, and the fan blade peripheral speed is lower, thereby reaches the purpose that reduces noise.Because the air intake panel in the left and right sides of cabinet air-conditioner, has therefore improved the air intake efficiency of air-conditioning effectively, thereby has improved the heat exchange efficiency of air-conditioning and reduce aerodynamic noise.
Traditional centrifugal blower is changed into the small size double suction fan of an outer rotor motor driven, external diameter is more much smaller than traditional fan blade, adopt a undersized double suction fan blade lower than the noise that adopts a single suction fan blade, waiting under the air quantity situation, novel air supply air-conditioner noise will reduce about 2dB (A), and because the directive property of fan noise is stronger, the noise of the cabinet-type air conditioner noise ratio front air intake of side air inlet reduces 3dB (A) approximately.
Behind the fan starting, gas sucks from air intake panel 1, enters simultaneously from spiral case 4 two ends between the leaf road of rotary blade, and blade does work to gas, and the gas around blade hit when gas obtained energy produces the gas pressure pulsation, causes noise.When air flow stream is crossed blade, on blade surface, form boundary-layer, produce many vortexs, form noise.The inhomogeneous air-flow of blade exit also forms noise, and the size of centrifugation blade is big more, and noise figure is also high more.Gas enters spiral case with certain speed after leaving blade, blows out from wind outlet panel 8 by evaporimeter 9 backs.Because the utility model adopts undersized double-suction centrifugal pump fan blade, the two-way centrifugation blade that enters of air, air quantity is identical with common large scale centrifugation blade effect, therefore, has reduced noise figure, and household air-conditioner is optimized.
Above-mentioned listed specific implementation is nonrestrictive, and concerning the person skilled in the art of this area, in not departing from the utility model scope, various improvement and the variation carried out all belong to protection domain of the present utility model.
