Specific implementation mode
It is cabinet air-conditioner in the prior art in conjunction with shown in Figure 1 comprising shell 4 ' and setting are in shell 4 '
Wind shield 3 ', shell 4 ' further includes air outlet 6 ', and the windward side of wind shield 3 ' is wind-guiding face, which is perpendicular.
This kind of cabinet air-conditioner generally there are the problem of air outlet unevenness, on air outlet grate the most upper lattice wind speed of wind deflector with it is most next
Lattice differ larger, specific test data such as following table：
Due to outlet air unevenness problem, cause leaving air temp there are deviation, the most next lattice of wind deflector and most upper leaving air temp are poor
Away from larger, most next lattice are blown a cold wind over, specific test data such as following table：
By above-mentioned two table it is found that cabinet air-conditioner in the prior art, has two side air-outs up and down of air outlet not
, and up and down the larger problem of both sides leaving air temp deviations, this results in air conditioner to have the possibility blown a cold wind in heating so that
It experiences poor when user's use, be easy to cause customer complaint.
L1 ' in Fig. 1 is to throw away the inlet air flow path that the air come is reflected through wind shield 3 ' from centrifugal blower fan system,
L2 ' is the inlet air flow path that the air thrown away from centrifugal blower fan system is reflected without wind shield 3 ', it can be seen from the figure that
There are the reason of above problem to be, along the air that L2 ' flows, is thrown away from centrifugal blower fan system by evaporator part
Afterwards, carry out heat exchange after-blow to wind shield 3 ' above, by the reflection of wind shield 3 ', secondary heat exchange；It has been in air outlet at this time
6 ' tops, using the secondary reflection of back plate, air is left by the air outlet 6 ' of upper end；And the sky reflected without wind shield 3 '
Gas flows directly at the ceiling location of shell 4 ', is then flowed out from the air outlet 6 ' of upper end under the action of top plate, to
Cause the wind speed above air outlet 6 ' higher than lower section, leaving air temp is same.
Based on the above issues, applicant spy proposes this programme.
In conjunction with referring to shown in Fig. 2 and 3, according to an embodiment of the invention, wind shield includes plate body 1 and is arranged in plate body 1
The air dam 2 of side, air dam 2 protrudes from the medial surface 10 of plate body 1, and the height protruded is incremented by along direction from bottom to top.
The inside of wherein plate body 1 refer to plate body 1 windward side namely plate body 1 deviate from air outlet 6 side.
Due to being provided with air dam 2 on the plate body 1 of wind shield, and the height of air dam 2 is passed along direction from bottom to top
Increase, therefore can be during reflecting the air flowing inside air conditioner, by air dam 2 to the flowing side of air
To the adjustment for carrying out certain angle so that by the air-flow of 2 water conservancy diversion of air dam on plate body 1 and directed along air conditioner inside stream
Dynamic air-flow can be distributed in the upper and lower directions of air conditioner wind outlet so that the wind speed of the air outlet up and down of air-conditioning can be equal
It is even, and then ensure that the air outlet temperature of air conditioner is uniform, improve the usage experience of user.
Air dam 2 includes wind deflector, wind deflector from the medial surface 10 of plate body 1 away from medial surface 10 direction obliquely
Extend.
L1 in Fig. 2 is to throw away the air flowing that air dam of the air come through wind shield 3 reflects from centrifugal blower fan system
Path, L2 are the inlet air flow path that the air for throwing away to come from centrifugal blower fan system is reflected without the air dam of wind shield 3.Work as sky
When gas is flowed along the paths L1, after increasing wind deflector, wind deflector can form the wind-guiding face of pushing, therefore, when wind turbine is sent
When the air gone out flows through wind-guiding face, it can be pushed under the reflex of wind-guiding face, to reduce the reflection height of air, work as air
When carrying out secondary reflection through back plate, it can be flowed out from the lower position of air outlet 6, and along the paths L2 directed along in air conditioner
The air-flow of portion's flowing can be flowed out from the upper side position of air outlet 6, to be improved on the downside of air outlet by the air in the paths L1
Wind speed so that the gap of the wind speed of the both sides up and down of air outlet becomes smaller or unanimously so that air outlet goes out wind velocity more
Uniformly, and then ensure air outlet leaving air temp more uniformity up and down, obtain more preferably air-out effect.Air dam 2 can also
The structure of the wind-guiding face of pushing can be formed for non-platy structure, such as the arc block etc. of wedge block or uneven thickness.
Wind deflector include be located at wind-guiding face of the wind deflector far from 1 side of plate body, wind-guiding face be plane, cambered surface or corrugated surface,
As long as can be pushed to the air-flow for reaching wind-guiding face, the flow locations of the air after back plate reflects are reduced so that reflection
Air-flow can be more towards distribution on the downside of air outlet.
Angle between wind-guiding face and the medial surface 10 of plate body 1 is 7 ° to 10 °, and it is good to thereby may be ensured that wind-guiding face has
Angle of inclination, can to the angle of reflected gas stream adjust it is more reasonable, both ensured the reflected gas stream mainly effluent under air outlet
Go out, and reflected gas stream is avoided excessively can not normally to be flowed out by the blocking of wind shield, improves the air-out effect of reflected gas stream.
When wind-guiding face is cambered surface, cambered surface is inner concave arc surface, can further adjust the reflection angle of air-flow so that air-flow is anti-
There is more good reflection angle when being incident upon back plate, more uniform air-out effect can be formed at air outlet, further
The outlet air uniformity is improved, temperature uniformity is improved.
Angle of the wind deflector between plate body 1 is adjustable, and wind deflector can be made to be carried out according to the wind velocity that goes out of wind turbine
The adjustment of angle ensures that wind deflector can be suitable for the air-conditioning of different situations to improve the adaptability of wind deflector so that
Side air-out can more uniformly up and down for various types of air-conditioner air outlets.
In conjunction with shown in Figure 4, the medial surface 10 of plate body 1 includes concave part, and concave part and air dam 2 are along air-flow flowing side
To setting gradually, it is ensured that air dam 2 has larger wind-guiding face, forms greater area of wind-guiding to air-flow, further carries
The wind effect of high air dam 2.The medial surface 10 of plate body 1 uses concave part, can increase wind chamber volume, improves outlet air ability.
After above-described embodiment using the application, the wind conditions of air outlet are as shown in the table：
Air outlet temperature difference situation is as shown in the table：
From two tables as can be seen that in terms of existing technologies, the wind velocity lift of the most next lattice of wind deflector one
Times, wind speed improves obviously, and wind speed is more uniform.
In addition, the maximum temperature difference at air outlet becomes 7.8 DEG C from original 13.3 DEG C, the temperature difference improves obviously, substantially reduces
The uniformity of leaving air temp, especially in winter, it is possible to prevente effectively from the phenomenon that most next lattice are blown a cold wind over, improves making for user
With experience.
Above-mentioned wind shield is particularly suitable for rectangular cabinet-type air conditioner.
In conjunction with shown in referring to Fig. 1 and Fig. 2, according to an embodiment of the invention, air conditioner indoor unit includes shell 4, indoor heat exchange
Device 5, air outlet 6 and wind shield 3, wind shield 3 are above-mentioned wind shield 3, and wind shield 3 is located at below air outlet 6, and wind deflector
