When the wall-mounted air conditioner indoor unit is used for refrigerating, as shown in fig. 8, the second motor is used for driving the first air baffle 10 to deflect downwards, the outlet air flow of the wall-mounted air conditioner indoor unit forms two air flows at the air outlet 112, wherein the first air flow flows to the inner plate surface of the first air baffle 10, part of the first air flow is blown upwards and then naturally subsides, the refrigerating effect is good, the air flow is prevented from being directly blown to a user, the other part of the first air flow is diffused downwards through the air diffusing holes 3 in the first air baffle 10, and the part of the first air flow is cross-mixed with the second air flow on the outer plate surface of the first air baffle 10, so that the second air flow is dispersed to be changed into soft, and the wall-mounted air conditioner indoor unit has better non-wind-sensing air outlet effect.
Referring to fig. 9, in the second embodiment of the present invention, the difference from the first embodiment is that the casing 100 includes a lower volute casing 120, the wall-mounted indoor unit of an air conditioner is provided with a second air baffle 20 on an inner side surface of the lower volute casing 120, and the second air baffle 20 is rotatably connected to the lower volute casing 120, so that the second air baffle 20 is used to weaken an outlet airflow blown out from a gap at a lower edge of the air outlet 112, thereby achieving a better non-wind effect.
Specifically, both ends of the second wind deflector 20 have a rotating shaft, the lower volute 120 has a shaft hole for the rotating shaft to be inserted, and the lower volute 120 has a third motor connected to the rotating shaft to drive the second wind deflector 20 to turn.
Referring to fig. 10, after the first wind deflector 10 is opened, the second wind deflector 20 is turned outwards, and a portion of the airflow at the stop of the second wind deflector 20 flows downwards, so as to reduce the wind sensation of the outlet airflow blown out from the gap at the lower edge of the air outlet 112.
Referring to fig. 11, after the first wind deflector 10 is turned upwards at the same time, the second wind deflector 20 is turned 180 ° outwards, the first wind deflector 10 and the second wind deflector 20 enclose the air supply duct of the air outlet 112, so as to prolong the air supply distance of the air outlet, which is beneficial to supplying warm heat to the indoor bottom layer, thereby achieving the foot warming effect.
Referring to fig. 12, after the first wind deflector 10 is turned downward, the second wind deflector 20 is turned 180 ° outward, the first wind deflector 10 and the second wind deflector 20 enclose the air supply duct of the air outlet 112, and the air supply distance of the air outlet is extended, so as to facilitate the realization of rapid cooling at the initial stage of cooling.
Referring to fig. 12, in the present embodiment, on the premise of ensuring no wind-induced air output of the air conditioner, the air-diffusing range and the air-diffusing effect of the air conditioner are improved, and a plurality of air-diffusing holes 3 are formed through the second air baffle 20. And part of outlet air flow of the wall-mounted air conditioner indoor unit is diffused downwards through the air dispersing holes 3 on the second air baffle 20, and the air speed of the part of air flow is reduced, so that no wind feeling can be realized.
Referring to fig. 12 again, in the present embodiment, in order to reduce the space occupied by the second wind deflector 20 in the wind tunnel, an accommodating groove for accommodating the second wind deflector 20 is disposed on the inner side surface of the lower volute casing 120, so that when the second wind deflector 20 is not needed, the second wind deflector 20 is accommodated in the accommodating groove.
Referring to fig. 12, in this embodiment, in order to increase the non-wind-induced wind-dispersing range of the wall-mounted air conditioner indoor unit, the inner plate of the first wind deflector 10 is configured in a concave arc shape, so that the outlet wind can be diffused along the inner plate of the first wind deflector 10 to both sides, and the outlet wind is diffused in a hemispherical shape from the wind-dispersing holes 3 on the first wind deflector 10. Therefore, the inner plate surface of the first wind shield 10 is arranged in a concave arc shape, so that the wind-free wind-dispersing range of the wall-mounted air conditioner indoor unit can be effectively enlarged.
Referring to fig. 13, it is considered that if the air dispersing holes 3 are in a straight cylindrical shape and penetrate through the first air deflector 10, when the wall-mounted air conditioner indoor unit is used for cooling, the air flow passes through the air dispersing holes 3 and then directly blows to the outside, the air flow does not pass through the outer plate surface of the first air deflector 10, so that the temperature difference between the inside and the outside of the first air deflector 10 is large, and water vapor in the air is easily condensed into condensed water on the outer plate surface of the first air deflector 10.
Therefore, in this embodiment, to avoid the above situation, the outer end of the air dispersing hole 3 is arranged in an arc flaring shape from inside to outside. When the air current blows out from the inner plate surface air dispersing hole 3 of the first air deflector 10, the air current smoothly diffuses outwards to the outer plate surface of the first air deflector 10 at the flared end of the air dispersing hole 3, so that the temperature difference between the inner side and the outer side of the first air deflector 10 is balanced, and the formation of condensed water on the outer plate surface of the first air deflector 10 is avoided.
Referring to fig. 14, in other embodiments, in order to achieve a better non-wind-feeling effect, the penetration direction of the wind-dispersing holes 3 is curved, so that the first wind-blocking plate 10 or the second wind-blocking plate 20 is penetrated through the wind-dispersing holes 3 in a curved shape, and compared to the straight-tube-shaped wind-dispersing holes 3, in this embodiment, the wind resistance of the curved wind-dispersing holes 3 is larger, so as to more effectively reduce the wind speed of the airflow at the wind outlet 112, thereby achieving a better non-wind-feeling effect.
Referring to fig. 14, in the present embodiment, considering that the distance between two adjacent air dissipating holes 3 is not too large, otherwise, condensed water may be generated on the outer panel surface of the first wind deflector 10, so that the distance between the centers of two adjacent air dissipating holes 3 is limited to 5mm to 10 mm.
If the center distance between two adjacent air dispersing holes 3 is less than 5mm, the strength of the first air deflector 10 is poor due to the over-dense air dispersing holes 3, and the first air deflector is easy to deform; if the center distance between two adjacent air dispersing holes 3 is larger than 10mm, the air dispersing effect and the condensed water preventing effect are poor because the air dispersing holes 3 are too sparse. Therefore, the center-to-center distance between two adjacent air dispersing holes 3 is limited to 5 mm-10 mm, and specifically, the distance may be 6.5mm, 8.5mm or 9.5 mm.
Referring to fig. 14, in order to ensure that the first baffle has a better air diffusion effect, the aperture of the air diffusion hole 3 is 2mm to 5mm, such as 2.5mm, 3.5mm, or 4.5 mm. If the aperture of the air dispersing hole 3 is smaller than 2mm, the air resistance is large due to the small air dispersing hole 3, and the outlet air flow is difficult to diffuse out through the air dispersing hole 3; if the aperture of the air dispersing hole 3 is larger than 5mm, the air resistance is smaller due to the overlarge air dispersing hole 3, the air outlet air flow still has larger air speed after passing through the air dispersing hole 3, and the realization of non-wind-sensing air outlet of the indoor unit of the wall-mounted air conditioner is not facilitated.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or any other related technical fields, which are directly or indirectly applied to the present invention, are included in the scope of the present invention.
