Abstract
The utility model discloses a novel air outlet mesh enclosure of an outdoor air-conditioner, which is characterized by comprising a flow deflecting ring arranged at an air outlet of the outdoor air-conditioner, and a protection grid arranged on the flow deflecting ring. Compared with the prior art, the novel air outlet mesh enclosure has the advantages of effectively reducing noise, especially low-frequency noise, and avoiding flow diffusion.
Description
Technical field
The utility model relates to a kind of air-conditioning member.
Background technology
In order to prevent that foreign matter from entering air-conditioner outdoor unit, also in order to prevent to accidentally injure the people, all air-conditioner outdoor units all can be installed air outlet mesh.At present, the air-conditioning air outlet mesh can be divided into two kinds, the plastics air outlet mesh (as shown in Figure 1, 2, 3) and the metal air outlet mesh (shown in Fig. 4,5) of band diversion function.Wherein the plastics air outlet mesh with diversion function has certain height owing to its baffle liner 14, can play good diversion function, the air-flow of avoiding blowing out is dispersed, but because plastics intensity is limited, consider mould process simultaneously, grid width 12 and height dimension are bigger, not only influence air quantity but also can cause noise, especially low-frequency noise increases, and can influence the tonequality of air-conditioning.Metal air outlet mesh (shown in Fig. 4,5) is owing to adopt metallic grid, and under the prerequisite of proof strength, grid diameter 21 can be accomplished very little, thereby can avoid air quantity and The noise.But because it does not have baffle liner, but directly be fixed on the front panel 35 by buckle 22, therefore the air-flow of the spirality scattering to the periphery that blows out through axial-flow windwheel, under the drag effect of grid, cause air-out to be dispersed easily, the part air-flow parallel with the air outlet plane to around blow out, and sucked condenser again by axial flow blower and form " crossfire ", thereby influence the heat exchange effect of air-conditioning.
In order to describe the utility model background in detail, describe (as shown in Figure 6) in conjunction with its working condition.Air-conditioner outdoor unit is relevant with air-flow mainly contains top cover 31 axial-flow windwheels 32, motor 33, air outlet mesh 34, front panel 35, chassis 36, condenser 37 and electric machine support 38.In the running, axial-flow windwheel 32 is rotation at a high speed under the driving of motor 33, air-flow is blown out through air outlet mesh 34, and form negative pressure between axial-flow windwheel 32 and condenser 37, and then suck air, and then realize the purpose of heat exchange with certain temperature difference through condenser 37.The air-flow streamline that axial-flow windwheel blows out becomes the rotation divergent shape, if air outlet mesh has baffle liner, can allow the vertical air outlet of air-flow blow out.If but air outlet mesh does not have baffle liner, but adopt such as metal guard (shown in Fig. 4,5), the air-flow of so already dispersing stops because of the air outlet mesh grid, disperse even more serious, even the part air-flow is parallel and air outlet blows out, and under the effect of condenser negative pressure, suck blower fan again, shown in Fig. 3 airflow arrows, form " crossfire " thus influence heat exchange effect and efficient.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of can effectively reduce noise, especially low-frequency noise, can avoid the air-conditioning air outlet mesh of outdoor unit that looses and flow again.
The utility model is achieved in that and comprises the baffle liner that is arranged on the air-conditioner outdoor unit air outlet, is arranged on the protective grille on the baffle liner.The utility model combines the advantage of existing two kinds of air outlet mesh, can realize the diversion function of air-out on the one hand by baffle liner, avoid the stream that looses, and the employing metallic grid that diameter is less, intensity is high, not only can guarantee the windage minimum, under the constant prerequisite of wind wheel and motor, improve air quantity, reduce power, and can reduce the above noise of 2dB.It is ingenious to the utlity model has design, function admirable, characteristics such as convenient and practical.
Here, the water diversion part of the baffle liner of air outlet mesh has the above height of 5mm, and the protective grille of air outlet mesh is the circular metal bar of diameter below 4mm.
Install protective grille for convenience, have the hole or the draw-in groove of fixed protection grid on the baffle liner of air outlet mesh.
Have buckle and screw hole on the baffle liner of air outlet mesh, be used for air outlet mesh is fixed on the front panel of air-conditioner outdoor unit.
Compared with the prior art the utility model owing to adopted the combination of baffle liner and protective grille, therefore, has and can effectively reduce noise, especially low-frequency noise, and that can avoid again loosing and flow has a few.

The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is done and is described in further detail:
Shown in Fig. 7,8,9,10,11,12, the utility model air outlet mesh, it is made up of demountable baffle liner 61 and protective grille 62, and wherein protective grille 62 can be shown in Figure 11 square, also can do in the arc-shaped or spirality.Baffle liner 61 detailed formations can be referring to Fig. 7,8,9,10, and it is divided into and has the water diversion part 44 that is no less than 5mm height, is used for fixing the fixing hole 41 of protective grille 62, and is used for baffle liner is fixed on buckle 42 and screw hole 43 on the air-conditioner outdoor unit.Baffle liner can be made into square or circular arc accordingly according to the profile of protective grille.Protective grille 62 is welded by bonding jumper 52, and each bonding jumper can the simple arrangements squarely, can be the circular arc (as shown in figure 13) or the spirality of round dot with the air outlet center also.
Figure 14,15 is used for the specific embodiment of air-conditioner outdoor unit for the utility model.Wherein the utility model air outlet mesh (84) is fixed on the front panel 83 of off-premises station by buckle and screw hole.The common air-conditioner outdoor unit of the common formation of the condenser of front panel 83 and right plate 82, top cover 81, chassis 87, axial-flow windwheel 85, motor, electric machine support 86, compressor, pipe-line system and back.
In the running, axial flow blower has the air of a fixed difference difference from condenser sucks environment under the startup of motor, and carries out water conservancy diversion through the baffle liner of air outlet mesh, makes it vertical with air outlet and pass through protective grille and blow out.Because baffle liner has certain height, not only can play guide functions, avoid air-flow to around disperse, formation " crossfire ", but also can reduce " dissection " of air-flow and protective grille reduces eddy current crack greatly.In addition, because the diameter of protective grille is less, can makes windage drop to minimum under the prerequisite of proof strength, thereby air quantity is improved, power descends.Because reducing of grid diameter also can reduce low-frequency noise, improve the tonequality of air-conditioner outdoor unit greatly.
Actual test finds, adopt novel air outlet mesh after, cover on power of motor than plastic wire and reduce under 6% the prerequisite, it is nearly 10% that air quantity has improved, and noise has reduced more than the 2dB.Figure 16 is for joining the noise curve that improves the front and back air outlet mesh with the money air-conditioner outdoor unit.Still be the metal guard for the plastics guard no matter as can be seen from the figure, noise figure of the present utility model all has reduction, and especially relatively with the plastics guard, its low-frequency band noise obviously reduces a lot, thereby improves its tonequality greatly, the raising market competitiveness.
