The specific embodiment
As shown in Figure 4 and Figure 5, the off-premises station of air-conditioner of the present invention includes following structure: top cover 54, safety grids 56, pressure fan 60 and heat exchanger.Above-mentioned top cover 54 forms the top of off-premises station, is formed with the wind pushing hole 53 that is used to discharge air; Safety grids 56 is arranged on the top cover 54, is used to prevent that foreign matter from flowing into wind pushing hole 53; Pressure fan 60 and heat exchanger are arranged on above-mentioned off-premises station inside, and the circular chamber outer air makes outdoor air and room air carry out the medium of heat exchange cooling heating.
Above-mentioned pressure fan 60 is made of motor 61 and blowing fan 62.Motor 61 is arranged on the downside of safety grids 56, and its rotating shaft 61a prolongs formation downwards; Blowing fan 62 is arranged on the above-mentioned rotating shaft 61a, is used to transmit air.
Wherein, said fan 62 includes a plurality of blades 63, body 64 and the osculum on it 67.The center of above-mentioned a plurality of blade 63 forms with radial setting towards axle, is used for the force feed air; Above-mentioned body 64 is integrally formed in the central part of blade 63, is open above the above-mentioned body 64, and central authorities are formed with the secure bond hole 66 that is used for fixing in conjunction with the rotating shaft 61a of above-mentioned motor 61; At least more than one above-mentioned osculum 67 is formed on a side, flow into the water of body 64 inside when discharging rainy or washing by wind pushing hole 53.
The central part of above-mentioned safety grids 56 is formed with tabular fixed part 58, is formed with a plurality of fixing hole 58a that are used for fixing motor 61 in the said fixing portion 58; Be formed with the grid portion 57 of sieve aperture (MESH) or web frame around the said fixing portion 58, above-mentioned grid portion 57 is used to cover the edge of wind pushing hole 53 and the space between the fixed part 58.
In addition, carriage 61b is installed on the motor 61, is formed with corresponding installing hole 61c on the carriage 61b with said fixing hole 58a; Secure bond parts by screw or rivet RIVET etc. are said fixing hole 58a and installing hole 61c fixedly.
Wherein, said fixing hole 58a and installing hole 61c form with equidistant formation or left and right symmetrically along circumferencial direction, the minimum vibration that makes motor 61 generations.
In addition, because the rear portion that said fixing portion 58 can fully cover motor 61 convexes to form to upside,, also can prevent to flow into motor 61 even rain or have water to flow into during cleaning.
On the one hand, the rotating shaft 61a of above-mentioned motor 61 is arranged on the fixed part 58 towards downside, makes can link blowing fan 62 on the rotating shaft 61a of downside, makes wind pushing hole 53 be positioned at the upside of motor 61.
So, for blowing fan 62 being driven by motor 61 and discharging air, need above-mentioned motor 61 to be rotated towards the direction opposite with the direction of rotation of prior art by wind pushing hole 53, perhaps suitably change the paddle shape of blowing fan 62.
Shown in Fig. 6,7, on go back blowing fan 62 body 64 below be formed with osculum 67, make and to discharge the water that flow into body 64 downwards that osculum 67 serve as spool with radial arrangement formation with secure bond hole 66 by osculum 67.
In addition, be formed with guide rail 65 in above-mentioned body 64, guide rail 65 projects upwards formation around secure bond hole 66, guide the insertion of above-mentioned rotating shaft 61a; Be formed with a plurality of timbers 68 between guide rail 65 and above-mentioned body 64 inwalls, a plurality of timbers 68 can prevent said fan 62 distortion and can reinforcement because osculum 67 causes the intensity that dies down.
At this moment, timber 68 is formed between the above-mentioned osculum 67, prevents that osculum 67 from being blocked by above-mentioned timber 68 or interdict.
In addition, a side of above-mentioned timber 68 is formed with flute profile rib 69, and section configuration vertically is formed on the above-mentioned timber 68 with the above-mentioned flute profile rib 69 that circle forms, and is used for the intensity of the above-mentioned timber 68 of reinforcement.
That is to say, be formed with osculum 67 in said fan 62, above-mentioned osculum 67 is to the outside discharge water of body 64, and anti-sealing amasss in above-mentioned body 64 inside; By timber 68 reinforcement are set because above-mentioned osculum 67 causes the intensity that dies down.
In addition, the flute profile rib 69 that the section size is bigger than the thickness of timber 68 is integrally formed in a side of above-mentioned timber 68, can prevent the distortion of above-mentioned timber 68.
Above-mentioned flute profile rib 69 can flatly form, and still preferably is vertically formed for easy injection mo(u)lding.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
