Abstract
The invention discloses an air outlet mesh of an outdoor unit of an air conditioner, which comprises a frame body and a grate, wherein the grate is arranged in the frame body and comprises a plurality of annular strips; a plurality of radial strips are arranged between the adjacent annular strips; and the air guide surfaces of the radial strips and the axial direction of the frame body form an acute angle. The air outlet mesh of the outdoor unit of the air conditioner can increase the circulating air volume of an outdoor unit, reinforce the heat exchange effect of a heat exchanger, improve the air-conditioner performance and save energy sources.
Description
Technical field
The present invention relates to air-conditioning technical field, relate in particular to a kind of air outlet mesh of outdoor unit of air conditioner.
Background technology
On air-conditioner outdoor unit, the operated by rotary motion air outlet mesh.The main effect of air outlet mesh of outdoor unit of air conditioner provides the security protection to air-conditioner outdoor unit, but this kind air outlet mesh has certain barrier effect to the air-out of off-premises station, this point is not paid attention to by most air-conditioning manufacturer, the design of the air outlet mesh of air-conditioner outdoor unit mostly, all be how to coordinate to consider, really do not consider from the outdoor air flow field with complete machine from the outward appearance of air outlet mesh.
When air-conditioner was worked, by aerofoil fan, thereafter, air was not the axial flow along aerofoil fan under the forced convertion of the aerofoil fan of air in being arranged on air-conditioner, but was the oblique rotational flow at center with the axle center of fan.
Existing air outlet mesh of outdoor unit of air conditioner, referring to accompanying drawing 1, its barrier wind-guiding face all adopts and is parallel to the design of air outlet mesh axle center, be not inconsistent with the airflow direction of reality, air need change airflow direction by grid, this has just increased the resistance of air by the air outlet mesh grid, thereby influences air circulation, influences off-premises station heat exchange effect.The patent No. is 200720127941.6 Chinese utility model patent a kind of novel air outlet mesh of openly knowing clearly, but its main purpose is to prevent that rainwater, foreign matter from entering air-conditioner outdoor unit.
Summary of the invention
The object of the present invention is to provide a kind of air outlet mesh of outdoor unit of air conditioner, structural design meets the off-premises station air flow field, improves the heating air conditioner performance, energy savings.
Air outlet mesh of outdoor unit of air conditioner of the present invention, comprise framework, and be arranged on the grid in the described framework, described grid comprises some annular bar, be provided with some radially bars, the wind-guiding face of described radially bar and axially acutangulating of described framework between the described adjacent annular bar.
The aerofoil fan that cause is arranged in the air-conditioner outdoor unit is an axially symmetric structure, and the air-out air-flow also is similar to axial symmetry, and therefore, air outlet mesh grid general shape adopts circulus, reduces in the interference of radial direction to air-flow.Some radially bars are set between annular bar, and described radially bar favours the framework setting, and promptly radially the axis of the wind-guiding face of bar and described framework is not parallel, forms an angle.When air outlet mesh is installed on the air-conditioner outdoor unit, described radially bar also can with the aerofoil fan axioversion, form an acute angle angle.Because bar inclination certain angle radially, its wind-guiding face conforms to the actual airflow direction, and air-flow is more smooth and easy, and grid is littler to the obstruction of air-flow.Angle of inclination and fan structure, revolution and guard and fan distance have certain relation.Generally speaking, far away more apart from the axle center, the angle of inclination also should be big more.And for the fan of different rotation directions, the incline direction of grid is opposite.
Preferably, described annular bar is the annular bar.
Preferably, described annular bar is the oval ring bar.
Preferably, the wind-guiding face of described radially bar and described framework axial becomes 10 °～60 ° angles.
Preferably, the wind-guiding face of described radially bar and described framework axial becomes 20 °～50 ° angles.
Preferably, the wind-guiding face of described radially bar and described framework axial becomes 30 ° of angles.
Air outlet mesh of outdoor unit of air conditioner of the present invention, framework is set and annular bar is set in framework, radially bar is set between the adjacent annular bar, thereby formation grid, because the radially axioversion setting of bar and framework, radially the wind-guiding face of bar and framework axially form the acute angle angle, consistent with the direction of actual air-out air-flow, make air-flow more smooth and easy, grid is littler to the obstruction of air-flow, and therefore air outlet mesh of outdoor unit of air conditioner of the present invention can increase the off-premises station air circulation, strengthens heat exchanger heat exchange effect, improve heat pump performance, energy savings.

The specific embodiment
For a better understanding of the present invention, the invention will be further described below in conjunction with embodiment, but the scope of protection of present invention is not limited to the described scope of embodiment.
Referring to Fig. 2, in the present embodiment, air outlet mesh of outdoor unit of air conditioner comprises framework 1, some annular bars 2, between adjacent annular bar 2, also is provided with several radially bars 3.Referring to Fig. 3, this is 4 one-tenth angle α of axis of wind-guiding face 31,32 and the framework 1 of bar 3 radially.According to fan structures different in the air-conditioner outdoor unit, revolution, and the different distance of air outlet mesh and fan, the wind-guiding face of bar radially can be arranged to different angles with the axial angle that becomes of framework, generally between 10 °～60 °.
The air outlet mesh of outdoor unit of air conditioner of present embodiment, owing to some annulus bars are set and between adjacent annulus bar, radially bar are set, and radially the wind-guiding face of bar and air outlet mesh framework axially acutangulates angle, make the cell structure that forms meet the air-out air flow direction, therefore reduced the obstruction of air outlet mesh, increased air output the air-out air.With the 1.5P off-premises station is example, adopt air outlet mesh of the present invention after, through experimental verification, compare with traditional net cover structure, under the constant prerequisite of noise, per hour air quantity can increase 100 cubes～150 cubes.
More than air outlet mesh of outdoor unit of air conditioner provided by the present invention is described in detail.It is to be noted; the described content of the specific embodiment be for better implement the present invention preferred embodiment; protection scope of the present invention is not limited to the described technical scheme of above-mentioned embodiment; and should be as the criterion with the described flesh and blood of claims, any possible composition, content and technologic change is only otherwise the scope that the flesh and blood that breaks away from claim of the present invention all belongs to the present invention to be protected.
