The present invention relates to a kind of air regulator outdoor unit, the more special structure that relates to a kind of outdoor unit of saying, it can avoid the exhaust gas recirculation of air outlet slit.
The outdoor unit of the air regulator that one Daepori is logical has structure for example shown in Figure 6.The dividing plate 22 that the inside of its main body 21 is provided on the base is divided into heat-exchanging chamber 23 and machine chamber 24.In heat-exchanging chamber 23, be equipped with a heat exchanger 25 and an aerofoil fan 26, and in machine chamber 24,27, one of compressors are used to control the control device (not drawing) of compressor 27, and similarly device is assembled wherein.A toroidal annulus 28 is settled around the excircle of aerofoil fan 26, and exhaust outlet net grid 29 are fixed on bell-mouthed air outlet slit the place ahead.In the outdoor unit of making like this, when aerofoil fan 26 drove rotation by a fan motor 30, air outside was drawn in the main body 21 by the A direction.Air is subjected to heat exchange at heat exchanger 25 internal diameters, and the placement blades flows along aerofoil fan arrives air outlet slit then, and is discharged into the outside by exhaust net grid 29.Yet, in the outdoor unit of this routine, in order to allow air stream discharge farther along rectilinear direction, the wheel hub 31 of aerofoil fan 26 is made into a kind of cylinder, and here the external diameter of leading edge (at the external diameter of fan motor 30 1 sides) equates with the external diameter (at the external diameter of air outlet slit side) of its trailing edge haply.The shape of horn mouth 28 except the air intake side, is a kind of simple circle, and its wall is parallel with the periphery of wheel hub 31, and the strut rail of exhaust net grid 29 is also towards the place ahead.
But in recent years, because housing condition day by day increases the restriction of the outer cell position of installation room, for example an outdoor unit is installed in a place, there is not sufficient space there between the metope in the air outlet slit of outdoor unit and another house, family, the air stream of discharging from above-mentioned outdoor unit impacts, such as, on the metope in another house, family and reflux, just some problems have been caused, descend as the air discharge function, the heat exchanger effectiveness of outdoor unit descends, and the metope in another house, family is owing to the influence of discharging air stream is made dirty.Moreover, because the structure of conventional exhaust net grid makes the internal structure of outdoor unit cover all at one glance, also make the outward appearance of outdoor unit and building inharmonious.
An object of the present invention is to provide a kind of outdoor unit of air conditioner,, thereby can guarantee original heat exchange function even it does not reduce degassing function can have a face wall or similar meeting to stop to discharge the barrier of air stream in air outlet the place ahead the time yet.
Structure according to the outdoor unit of a kind of air conditioner of the present invention is as described below.Inside at main body is divided into a Heat Room and a machine chamber with dividing plate, and a heat exchanger and an aerofoil fan are installed in heat-exchanging chamber, a compressor, and a cover is used to control the control device of compressor, or similar device is installed in the machine chamber.An annular horn mouth centers on the excircle of described aerofoil fan, and exhaust net grid are installed in the place ahead of air outlet.Here, the external diameter of the trailing edge of described aerofoil fan wheel hub is made the external diameter greater than its leading edge, thereby the periphery of wheel hub becomes the inclined plane with its length direction, and the surface of described horn mouth outlet side is also done to such an extent that roughly parallel with the circumference of hub inclined-plane.Moreover the crosspiece of described exhaust net grid is also made vertical or level.The strut rail that is installed in the right and the left side tilts to the right and to the left front respectively, the strut rail that is installed in bottom and upper segment in other words respectively up and down the place ahead tilt and rightmost and Far Left or be made into parallel with described horn mouth outlet side inclined-plane haply with the surface of strut rail bottom topmost at least.
Because this structure from the air-flow of aerofoil fan air intake effluent to the air outlet slit side, will outwards flow along the periphery of aerofoil fan wheel hub.Because the strut rail of exhaust net grid is made into to the right and tilt left or up and down, air stream by aerofoil fan just is guided to the right and is tilted to outer direction left or up and down, even do not have under the situation in enough spaces between the air outlet slit of air conditioner outdoor unit and its opposite building wall like this, the air of discharge stream also can be gone out far.
Therefore, the air stream of discharge is discharged forward sideling, even the space between air outlet and another house is very narrow, the metope hole in another house can not made dirty yet.Moreover because the air of discharging stream can not recoil to outdoor unit, the discharge function of air is enhanced, thereby exchange capability of heat is enhanced.Because the strut rail of exhaust net grid tilts, the inside of outdoor unit be cannot see from the front, and its outward appearance is therefore improvement also, and easier and building is harmonious.
