The specific embodiment
Hereinafter, with the outdoor unit that is described in detail with reference to the attached drawings according to the air-conditioner of first embodiment.
Fig. 1 is the stereogram that illustrates according to the outdoor unit of the air-conditioner of first embodiment.Fig. 2 is the stereogram that illustrates according to the major part of the outdoor unit of the air-conditioner of first embodiment.Fig. 3 is the cutaway view that illustrates according to the major part of the outdoor unit of the air-conditioner of first embodiment.
With reference to figure 1, casing 10 defines the outward appearance of outdoor unit 1.The inlet hole (not shown) that is used for sucking room air is limited at casing 10 with the tap 20 that is used to discharge the air in the casing 10.Discharging grid 30 is arranged in the tap 20.
The various piece of forming the heat exchange circulation is installed in the casing 10.For example, tube-axial fan 40 (see figure 2)s, fan electromotor (not shown), outdoor heat converter (not shown), compressor (not shown) and accumulator (accumulator) (see figure 2) are installed in the casing 10.
Tube-axial fan 40 forms inside or the outside air-flow that sucks or be discharged to casing 10 through inlet hole and tap 20.Fan electromotor is provided for making the driving force of tube-axial fan 40 rotations.Outdoor heat converter is used as condenser during refrigerating operation, and is heating operating period as evaporimeter.When the cold-producing medium of circulation is at inflow outdoor heat exchanger in the heat exchanger circulation, with flow air is carried out heat exchange through the operation of tube-axial fan 40.The cold-producing medium of compressor compresses circulation heat exchange circulation.
Referring to figs. 2 and 3, comprise that the tube-axial fan of hub 41 and a plurality of blades 43 uses as tube-axial fan 40.Rotating shaft is connected to hub 41.In addition, a plurality of blades 43 are arranged on the outer surface of hub 41.
Each blade 43 comprises taper (tip) 44 and leading edge 45 and trailing edge 47, and taper 44 is restricted to the end of blade 43, and leading edge 45 is restricted to the two ends that hub 41 are connected to taper 44 respectively with trailing edge 47.According to the direction of rotation of blade 43, the front end of blade 43 can be described as leading edge 45, and the rear end of blade 43 can be described as trailing edge 47.
At length, rotation aperture part 110 can be fixed to the position of the taper 44 of blades adjacent 43.Be fixed to the flow direction that the rotation aperture part 110 of blade 43 can be parallel to through tube-axial fan 40 flow air, perhaps tilt less than the angle of an acute angle with respect to this flow direction.
In the present embodiment, a plurality of auxiliary blades 111 are set at the outer surface of rotation aperture part 110.A plurality of auxiliary blades 111 can be along the outer surface that rotates aperture part 110 with about identical distance setting.
When rotation aperture part 110 rotated with tube-axial fan 40, each auxiliary blade 111 made air flow along a direction, and this direction is identical with the flow direction of the rotation flow air of passing through tube-axial fan 40.
Fixed orifice part 120 is placed in the casing 10.In addition, as rotation aperture part 110, fixed orifice part 120 can guide through tube-axial fan 40 flow air, to increase constant pressure.Fixed orifice part 120 is not independent member.For example, be used for fixing the member of discharging grid 30 and can be used as fixed orifice part 120.
Therefore, the inner periphery in aperture 121, i.e. the front end of fixed orifice part 120 can be along the direction perpendicular to the flow direction through tube-axial fan 40 flow air, and separates with the outer surface of rotation aperture part 110.
