Abstract
The utility model relates to an air conditioner, which comprises a centrifugal air fan (1) and an air fan motor (2). The parts of a central bracket (5) and a back cover (4), which correspond to the front end and the lower end of the centrifugal air fan (1), are both closed plates. The centrifugal air fan (1) is enclosed into a semi-enclosed structure by the central bracket (5). An air inlet (6) is arranged at the back end of the central bracket (5). An air guiding opening 7 is arranged on the side edge of the central bracket (5). An air channel cavity (8) is formed between the central bracket (5) and the back cover (4). The air intake noise of the centrifugal air fan of the utility model can not be easily sent out of the air conditioner. The central bracket has an integral structure. Noise is well sealed in a machine casing. Compared with the existing same air conditioner, the noise of the air conditioner of the utility model can be decreased by 6-10 decibels or so.
Description
The utility model relates to a kind of air-conditioner, especially relates to a kind of low-noise air conditioner.
The supply air system of existing air-conditioner mainly contains three kinds, i.e. aerofoil fan supply air system, cross-flow fan air-supply system and centrifugal fan supply air system etc.In the centrifugal fan supply air system, generally adopt the front to concentrate the mode of air intake, promptly face on the front panel of centrifugal fan inlet scoop and have air inlet.When room air was inhaled into centrifugal fan, air produced quite big noise with the flabellum meeting of interaction of rotation at a high speed; Also will produce a part of noise when on the other hand, centrifugal fan and motor move.Because in fact the air inlet of this structure air-conditioner front panel does not keep apart centrifugal fan inlet scoop or fan and motor itself and the interior space, is directly to propagate in the room so noise that the centrifugal fan air draught is produced and motor and fan move the noise that is produced.The noise of experiencing the air-conditioner complete machine in the room is just bigger, can not satisfy high-quality household requirement.
The purpose of this utility model is to provide a kind of and has more low noise air-conditioner by improving the air draught mode.
For achieving the above object, the utility model adopts following technical proposals: air-conditioner, comprise centrifugal fan, fan electromotor, fan electromotor embeds in the centrifugal fan, and centrifugal fan is fixed on the center bearing bracket by fan electromotor, and center bearing bracket and back cover are closure plate corresponding to the position of centrifugal fan front and back end, center bearing bracket surrounds semi-enclosed structure with centrifugal fan, there is air inlet its rear end, and side has the wind-guiding air port, forms the chamber, air channel between center bearing bracket and back cover.
As a kind of improvement, the chamber, air channel of air-conditioner can be bending, and its wind passage mouth is positioned on the air-conditioner front panel.
The wind passage mouth in the chamber, air channel of the utility model air-conditioner can also be positioned on the outer cover of the air-conditioner left and right sides.
On the other hand, the heat exchanger of air-conditioner can be installed between chamber, air channel and the centrifugal fan rear end.
The scheme that can take as another kind, the utility model air-conditioner, comprise centrifugal fan, fan electromotor, fan electromotor embeds in the centrifugal fan, and centrifugal fan is fixed in by fan electromotor on the back cover of air-conditioner, and the front panel of air-conditioner and back cover are closure plate corresponding to the position of centrifugal fan front and back end, center bearing bracket surrounds semi-enclosed structure with centrifugal fan, its front end has air inlet, and side has the wind-guiding air port, forms the chamber, air channel between center bearing bracket and front panel.
The front panel of the utility model air-conditioner and back cover are closure plate corresponding to the position of centrifugal fan front and back end, and centrifugal fan sucks room air by the chamber, air channel.The utility model changes the air draught mode of centrifugal fan, and the existing mode that directly from the front wind is sucked by centrifugal fan is changed into wind from different directions, through sucking in the centrifugal fan behind the chamber, one section air channel again.The induction noise that centrifugal fan is produced when sucking room air owing to be against the wind, is difficult for spreading out of outside the machine; In addition, center bearing bracket is an overall structure, and the noise that produces in the time of can be with the operation of fan and motor is sealed in the casing preferably, thereby reaches the purpose that reduces total noise of centrifuge.Under the equivalent technology condition, the comparable existing air-conditioner of the noise of the utility model air-conditioner reduces about 6-10 decibel.
