According to a first aspect of the embodiments of the present invention, an air outlet structure of an air conditioner is provided.
As shown in fig. 3, in an alternative embodiment, the air outlet structure of the air conditioner includes:
the first air deflector 41 is arranged in a first static pressure cabin 51 at the upper part of the air conditioner, the first surface of the first air deflector is a first curved surface with a first set curvature, and the first curved surface can guide air blown to the first curved surface from an upper air outlet 71 of the air conditioner to the outside of the air conditioner;
and/or the presence of a gas in the gas,
and the second air deflector 42 is arranged in the second static pressure cabin 52 at the lower part of the air conditioner, the second surface of the second air deflector is a second curved surface with a second set curvature, and the second curved surface can guide the air blown to the first curved surface from the lower air outlet 72 of the air conditioner to the outside of the air conditioner.
The first guide plate 41 and/or the second guide plate 42 may reduce the risk of generating a vortex when the air conditioner is outputting air, or even not generate a vortex, thereby reducing the noise of the output air. When the air outlet structure only comprises the first guide plate 41, the air outlet structure is suitable for an air conditioner only provided with the upper air outlet 71; when the air outlet structure only comprises the second guide plate 42, the air outlet structure is suitable for the air conditioner only provided with the lower air outlet 72; when the air outlet structure includes the first guide plate 41 and the second guide plate 42, the air outlet structure is suitable for an air conditioner with an upper air outlet 71 and a lower air outlet 72.
One end of the first curved surface close to the upper air outlet 71 is tangent to the top surface of the inner side of the first static pressure cabin 51, and one end of the first curved surface far away from the upper air outlet 71 is tangent to the vertical side surface of the first static pressure cabin 51 far away from the upper air outlet 71.
The first set curvature of a point on the first curved surface is related to the first distance between the point and the upper air outlet 71, and the larger the first distance is, the larger the first set curvature is. The first guide plate 41 with the proper first set curvature can ensure that the height of the upper air outlet 71 is reduced to the maximum extent under the condition of no vortex.
In order to accurately determine the first set curvature, the cross section of the first curved surface may be any one of a parabola and a hyperbola. When the cross section of the first curved surface is a parabola, the first set curvature has a linear relation with the first distance. The greater the cooling/heating power of the air conditioner, the greater the rate of change of the first set curvature with increasing first distance.
Correspondingly, one end of the second curved surface close to the lower air outlet 72 is tangent to the bottom surface of the inner side of the second static pressure cabin 52, and one end of the second curved surface far from the lower air outlet 72 is tangent to the vertical side surface of the second static pressure cabin 52 far from the lower air outlet 72.
The second set curvature of a point on the second curved surface is related to a second distance between the point and the lower air outlet 72, and the larger the second distance, the larger the second set curvature. The second guide plate 42 with the second set curvature suitable for the air outlet is arranged, so that the height of the lower air outlet 72 can be reduced to the maximum extent under the condition that no vortex is generated.
In order to accurately determine the second set curvature, the cross section of the second curved surface may be any one of a parabola and a hyperbola. When the cross section of the second curved surface is parabolic, the second set curvature has a linear relationship with the second distance. The greater the cooling/heating power of the air conditioner, the greater the rate of change of the second set curvature with increasing second distance.
As shown in fig. 4, in an alternative embodiment, the first curved surface of the first baffle plate 41 is provided with a first mixed flow inlet 43;
in an alternative embodiment, the second curved surface of the second baffle 42 opens the second mixed flow wind inlet.
Wherein, first mixed flow wind entry 43 and second mixed flow wind entry are used for inhaling the indoor air in the air conditioner, and will blow off the wind neutralization, under the prerequisite of guaranteeing the refrigeration/heating ability of air conditioner, guarantee that the difference between the temperature of the wind that the air conditioner blew off and the temperature of indoor air can not differ too much, improve the comfort level of blowing and experience.

When the air outlet structure only comprises the first rotary air supply assembly 61, the air outlet structure is suitable for the air conditioner only comprising the upper air outlet 71; when the air outlet structure only comprises the second rotary air supply assembly, the air outlet structure is suitable for the air conditioner only comprising the lower air outlet 72; when the air outlet structure comprises the first rotary air supply assembly 61 and the second rotary air supply assembly, the air outlet structure is suitable for an air conditioner which simultaneously comprises an upper air outlet 71 and a lower air outlet 72.
In an optional embodiment, the air outlet structure of the air conditioner further includes:
the air outlet end of the first air guide duct 31 is used for being communicated to the first static pressure cabin 51, the air outlet end of the first air guide duct 31 is fixed relative to the first guide plate 41, and the first curved surface guides air blown out from the first air guide duct 31 to the outside of the air conditioner through the upper air outlet 71 of the air conditioner;

In an optional embodiment, the air outlet structure includes a second air valve disposed in the second air guiding duct 32, and the second air valve is used for controlling on/off of the second air guiding duct 32.
When the air-out structure only included first wind-guiding wind channel 31, not only can controlled the air-out of air outlet 71, can also be through the further accurate control air output of first pneumatic valve, and on the same way, when the air-out structure only included second wind-guiding wind channel 32, the air output of the lower air outlet 72 of air conditioner can further accurate control by the second pneumatic valve. When the air outlet structure includes the first air guiding duct 31 and the second air guiding duct 32, the ratio of the air output of the upper air outlet 71 to the air output of the lower air outlet 72 can be adjusted by the opening and the on/off of the first air valve and the second air valve, or the air is exhausted only through the first air outlet/the second air outlet at a set time.

Similarly, in the process of the air flowing in the second wind guiding channel 32, the wind speed is gradually reduced, the air pressure is gradually reduced, and the noise is reduced. First wind-guiding wind channel 31 and first static ballast 51 mutually support, or second wind-guiding wind channel 32 mutually supports with second static ballast 52, further reduces the air-out dynamic pressure, increases the dynamic pressure, and the air-out is releived, and the comfort level is experienced.

The air outlet speed can be reduced to a set speed, and comfortable air blowing is realized. For example, the air outlet speed is reduced to 2.5m/s, 3m/s or 3.5m/s or less. The larger the refrigerating/heating power of the air conditioner is, the larger the air output of the air conditioner is, the faster the air outlet speed is, and the first cone angle and/or the second cone angle are/is increased, so that the effect of reducing the air speed can be realized, and comfortable blowing can be realized.
