Detailed description of the invention
Below, embodiments of the invention are described in detail with reference to accompanying drawing.
Fig. 1 is the stereogram of the air conditioner roughly illustrated according to a first embodiment of the present invention, and Fig. 2 is the sectional view according to air conditioner of the present invention, illustrates that front panel is by the state opened.
As depicted in figs. 1 and 2, air conditioner comprises according to an embodiment of the invention: the housing 10 opened above; Be arranged at the air exhausting device 11 of the lower space of housing 10 inside; Be arranged at the heat exchanger 13 of the upper space of housing 10 inside; The front panel 30 before housing 10 can be arranged at movably forward and backward; For the panel mobile device (not shown) of mobile front panel 30.
Front panel 30 is arranged at before housing 10 movably.Moved forward by front panel 30, between housing 10 and front panel 30, externally expose the air outlet 33 for discharging air.
Further, the two sides, bottom of front panel 30 have front wall 30 to the side air suction inlet 35 that externally exposes during the front reach of housing 10.
Side air suction inlet 35 enters into the inside of housing 10 when front panel 30 moves to closed position, only just externally expose when front panel 30 moves to enable possition.
Under the state that front panel 30 moves to enable possition, if air exhausting device 11 runs, then extraneous air is flow in air exhausting device 11 by the side air suction inlet 35 of air suction inlet 15 and the front panel 30 below of housing 10.
Flow into the air of air exhausting device 11 and be discharged to the heat exchanger 13 being arranged at housing 10 top, by externally being discharged by the air outlet 33 exposed under the state that moves to enable possition at front panel 30 through the air of heat exchange during heat exchanger 13.
Now, the two sides, top of front panel 30 possess airflow guide 31, and for when being discharged by air outlet 33 through the air of heat exchange, the front to housing 10 guides air.
If front panel 30 moves to closed position, then airflow guide 31 enters into the inside of housing 10, if front panel 30 moves to enable possition, then airflow guide 31 exposes to the side of air conditioner.Therefore, no matter front panel 30 is positioned at closed position or enable possition, and airflow guide 31 can not expose before air conditioner.
As shown in Figure 2, discharge air to be guided together with airflow guide 31 when front panel 30 opens, the inside, two sides being adjacent to the housing 10 of airflow guide 31 possesses the madial wall 17 extended along the longitudinal direction respectively.Madial wall 17 is formed as parallel with the discharge direction of air plane, and these are different from airflow guide 31.
Therefore, between the airflow guide 31 and the madial wall 17 of housing 10 be adjacent of front panel 30, form passing away, and can utilize and forwards to move along with front panel 30 and the spacing of the air outlet 33 of the lateral space formed between front panel 30 and housing 10 controls to discharge air-flow.That is, if when front panel 30 shifts out more forward, the width along with air outlet 33 becomes large, and the quantitative change of discharging air is many, discharges to towards laterally inclined front direction simultaneously.
And, if the width of air outlet 33 is narrower, the wind speed of the air of then discharging can accelerate, now, the air of discharge according to the airflow guide 31 of curved shape, due to the section's Anda effect (Coande Effect) flowed along curved shape, easily form air-flow forward.
Discharge blade 50 is arranged at front panel 30, and is assemblied in suitable pivot.
Fig. 3 is the schematic diagram of the shape of discharge blade according to a first embodiment of the present invention, shows the flowing of the discharge air-flow around discharge blade, Fig. 4 be Fig. 2 ' detail drawing of A ' part.
As shown in Figure 3, discharge blade 50 according to a first embodiment of the present invention comprises: outside aerofoil 101 and inner side aerofoil 102.
Outside aerofoil 101 and inner side aerofoil 102 connect and form end points (edge), the end points being wherein formed at front end is anterior end points (leading edge) 104, and the end points being formed at rear end is rear portion end points (trailingedge) 105.
Connect anterior end points 104 and be called wing chord (chord) 106 with the straight line of rear portion end points 105, and be called wing chord 106 direction by from anterior end points 104 along the direction of wing chord 106.
Thickness refers to, the distance between the point crossing with outside aerofoil 101 and inner side aerofoil 102 when drawing the straight line perpendicular to wing chord 106, wherein the length in thickness is called maximum gauge 107.
Discharge blade 50 has following shape.That is, thickness increases from anterior end points 104 along wing chord 106 direction and forms maximum gauge 107, and near rear portion end points 105, thickness reduces again.
Now, maximum gauge 107 is preferably more than 1/10 of wing chord 106 length.
Further, discharge blade 50 can have following thickness distribution.That is, with wing chord 106 for benchmark, inner side aerofoil 102 compare outside aerofoil 101 thicker.That is, outside aerofoil 101 is compared inner side aerofoil 102 and can be formed as milder.
Below, by discharge blade 50 is according to a first embodiment of the present invention applied on air conditioner, so that the principle that the speed of the principle that discharge air is concentrated and air is accelerated to be described.
As shown in Figure 3 and Figure 4, the air of discharging from air outlet 33 forms more stable flowing through discharge blade 50.
The discharge air flowed into from the anterior end points 104 of discharge blade 50 roughly separates centered by anterior end points 104, and flows along outside aerofoil 101 and inner side aerofoil 102 respectively.
The air flowed along outside aerofoil 101 and inner side aerofoil 102 is in the space formed with outside aerofoil 101 or the inner side aerofoil 102 of discharge blade 50 through airflow guide 31 or madial wall 17, and speed can increase.
If phenomenon as above is based on the speed increase when fluid is through relative narrower interval, the result of " Bernoulli Jacob (Bernoulli) principle " of pressure drop.
Further, according to continuity law, the air separated centered by the anterior end points 104 of discharge blade 50 should converge at rear portion end points 105 after outside aerofoil 101 and inner side aerofoil 102 flow simultaneously.Because discharge blade 50 is according to a first embodiment of the present invention formed as with wing chord 106 as benchmark, inner side aerofoil 102 compares the thicker shape of outside aerofoil 101, and the air therefore flowed along inner side aerofoil 102 is compared the air flowed along outside aerofoil 101 and should be flowed after farther distance and arrive rear portion end points 105 simultaneously.
Therefore, have and make the speed of air flowed along inner side aerofoil 102 become effect faster.
As mentioned above, the discharge air that speed is accelerated is forming interflow again when the rear portion end points 105 of discharge blade 50, and the direction at interflow, namely separately almost identical with the discharge direction of air with make a concerted effort (arrow with reference to shown in Fig. 4) of the velocity attitude of the air flowed along inner side aerofoil 102 along the velocity attitude of air of outside aerofoil 101 flowing centered by anterior end points 104, thus the speed of discharging air can improve further.
The spacing with airflow guide 31 or madial wall 17 is reduced by the thickness strengthening discharge blade 50, improve the speed of air thus, and with wing chord 106 for benchmark, make inner side aerofoil 102 compare outside aerofoil 101 and be formed as thicker, improve the speed of the air flowed along inner side aerofoil 102 thus, and pass through from anterior end points 104 along wing chord 106 direction, after thickness increases, the shape that thickness diminishes again near rear portion end points 105, the air flowed along outside aerofoil 101 and inner side aerofoil 102 is made to focus on predetermined place through rear portion end points 105, improve the speed of air thus.
Therefore, there is discharge air that speed as above is increased and can arrive effect from the region away from air conditioner.
Further, the air flowed along outside aerofoil 101 and inner side aerofoil 102 focuses on predetermined place after rear portion end points 105, therefore can divide the region that there is air-flow and the region that there is not air-flow clearly.

As shown in Figure 5, discharge blade 51 according to a second embodiment of the present invention has following shape.That is, from anterior end points 204 along wing chord 206 direction, thickness increases and forms maximum gauge 207, and the interval forming maximum gauge 207 maintains more than 2/3 of wing chord 206 length along wing chord 206 direction, and near rear portion end points 205, thickness reduces again.
As shown in Figure 6, discharge blade 52 according to the third embodiment of the invention has following shape.That is, from anterior end points 304 along wing chord 306 direction, thickness increases and forms maximum gauge 307, and the interval forming maximum gauge 307 maintains more than 1/3 of wing chord 306 length along wing chord 306 direction, and near rear portion end points 305, thickness reduces again.
As shown in Figure 7, discharge blade 53 according to a fourth embodiment of the present invention for illustrating the position that maximum gauge 407 is formed, from anterior end points 404 along wing chord 406 direction, thickness increase, and roughly wing chord 406 length 1/2 position formed maximum gauge 407.
In order to improve performance, the position of maximum gauge 407 can be changed arbitrarily.Such as, maximum gauge also can be formed in be less than chord length 1/10 position, or be formed in more than 1/10 of chord length and be less than the position of 1/3 of chord length, or be formed in chord length more than 1/3 position.
