The embodiments described in the figures are exemplary and intended to be illustrative of the invention and are not to be construed as limiting the invention.
An air conditioning indoor unit 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 10. In which the indoor unit 100 and the outdoor unit are assembled together to form an air conditioner for adjusting the indoor ambient temperature.

As shown in fig. 1, an air conditioning indoor unit 100 according to an embodiment of the present invention includes: the air conditioner comprises a machine body 1, an outer air deflector 2 and an inner air deflector 3. All the components of the indoor unit 100 of the air conditioner are installed in the machine body 1, and the machine body 1 can play a role in supporting and protecting internal components on one hand and can also play a certain decorative effect on the other hand.
The machine body 1 comprises a chassis, a face frame and a panel, wherein the face frame is arranged on the chassis, the front side of the face frame is open, the panel is arranged on the front side of the face frame, and an air outlet 11 is defined between the lower end of the panel and the face frame. Specifically, the face frame can be rotatably or detachably arranged on the chassis, and the panel can be rotatably or detachably arranged on the face frame. It can be understood that the inside of the machine body 1 is provided with an air outlet frame for circulating air, and the indoor unit of the air conditioner further comprises elements such as a heat exchanger, a fan, an electric control box and the like arranged in the machine body 1.
Specifically, the machine body 1 is provided with an air outlet 11; the outer air deflector 2 is arranged at the air outlet 11, and the outer air deflector 2 is used for opening and closing the air outlet 11; for example, the outer wind deflector 2 may be pivotally connected to the edge of the outlet 11, and the outlet 11 may be opened and closed by rotating the outer wind deflector 2. When the air outlet 11 is opened by the outer air deflector 2, the airflow can be blown into the room through the air outlet 11, at this time, the outer air deflector 2 can play a role in guiding the blown airflow, and when the air outlet 11 is closed by the outer air deflector 2, the outer air deflector 2 is flush with the outline of the outer edge of the machine body 1.
Of course, it can be understood that, during the operation of the air conditioning indoor unit 100, the outer air guiding plate 2 may also rotate around the rotating shaft of the outer air guiding plate 2 to swing the air.
The outer air deflector 2 is provided with an air dispersing area, which is an area capable of discharging air on the outer air deflector 2, and the air in the indoor unit of the air conditioner can be discharged through the air dispersing area without opening the outer air deflector 2. The structure of the wind dispersing area can be various, for example, the wind dispersing area can be constructed into a large number of micropores, or openings are arranged on the outer wind deflector 2, and a net-shaped material is laid at the openings. Of course, it is understood that the structure of the wind dispersing area may be various, and the present invention does not limit the specific structure or material of the wind dispersing area.
Preferably, the air dispersing area has a plurality of air dispersing holes 21, and the outer air guiding plate 2 may have a plurality of air dispersing holes 21 penetrating in the thickness direction. Wherein, optionally, the cross section of the air dispersing hole 21 is circular, oval, triangular or polygonal.
Further, the outer wind guide plate 2 is rotatable between a non-wind sensing state (e.g., the state of the outer wind guide plate 2 shown in fig. 5) and an open state (e.g., the state of the outer wind guide plate 2 shown in fig. 7). The air outlet 11 is opened when the outer air deflector 2 is in an open state, and the air outlet 11 is closed when the outer air deflector 2 is in a no-wind-sensing state.
As shown in fig. 4 and 5, when the outer air deflector 2 closes the air outlet 11 in the no-wind-sensation state, the airflow in the machine body 1 can be blown out through the air-dispersing holes 21 on the outer air deflector 2, at this time, the indoor unit of the air conditioner is in the no-wind-sensation mode, the outer air deflector 2 can play a certain blocking effect on the blown airflow, and only the airflow is allowed to be blown out through the air-dispersing holes 21, so that the wind speed and the wind volume can be reduced, the wind tends to be no-wind, and the no-wind-sensation effect is achieved. Effectively avoid suffering from air conditioning disease because the air current directly blows the people, user experience is better. At this time, the air-conditioning indoor unit is in a no-wind-sense mode.
As shown in fig. 6 and 7, when the air outlet 11 is opened by the external air deflector 2 in the open state, the airflow is directly blown out from the air outlet 11, and the air-conditioning indoor unit is in the air-sensitive mode.
The inner air deflector 3 is arranged at the air outlet 11, the inner air deflector 3 is positioned at the inner side of the outer air deflector 2, and the inner air deflector 3 is used for opening and covering at least one part of the outer air deflector 2. That is, when the outer air guiding plate 2 closes the air outlet 11, the inner air guiding plate 3 can open or cover at least a portion of the outer air guiding plate 2. For example, the inner air guiding plate 3 is rotatably disposed at the air outlet 11, and the inner air guiding plate 3 can be rotated to open and cover the outer air guiding plate 2.
Specifically, when the inner wind guide plate 3 rotates perpendicular to the wind outlet direction, as shown in fig. 2, the inner wind guide plate 3 may cover at least a portion of the outer wind guide plate 2, and when the inner wind guide plate 3 rotates parallel to the wind outlet direction, as shown in fig. 5, the inner wind guide plate 3 opens the outer wind guide plate 2, that is, the inner wind guide plate 3 does not block the airflow from flowing to the outer wind guide plate 2.
Of course, it is understood that the inner wind deflector 3 can also rotate around its pivot axis to swing the wind, i.e. to adjust the direction of the air flow blowing towards the outer wind deflector 2.
According to the air conditioner indoor unit provided by the embodiment of the invention, the plurality of air dispersing holes 21 are formed in the outer air deflector 2, so that when air flow is blown out through the air dispersing holes 21, the air speed and the air quantity can be effectively reduced, the air flow is prevented from directly blowing to a human body, the effect of no wind sense is realized, and the user experience is improved.
In one embodiment of the present invention, the sum of the areas of the plurality of air dispersing holes 21 on the outer air guiding plate 2 is not less than 50% of the total area of the outer air guiding plate 2. Therefore, the refrigeration and heating efficiency of the indoor environment can be ensured on the premise of reducing the air speed and the air quantity of the outlet air.
Here, the total area of the outer wind guide plate 2 includes the area of the wind dispersing holes 21 of the outer wind guide plate 2.
The diffuser hole 21 may include a first hole section 211 and a second hole section 212 connected in the outlet direction, and an outlet size of the first hole section 211 is different from an inlet size of the second hole section 212 to form a parting plane 213. That is, the outlet size of the first bore section 211 may be larger than the inlet size of the second bore section 212, or the outlet size of the first bore section 211 may also be smaller than the inlet size of the second bore section 212.
In some embodiments of the present invention, as shown in fig. 3, the diffuser hole 21 may include a first hole section 211 and a second hole section 212, the first hole section 211 and the second hole section 212 are sequentially connected along the outlet direction (e.g., the direction of the arrow shown in fig. 5), and the outlet size of the first hole section 211 is smaller than the inlet size of the second hole section 212, so that a parting plane 213 is formed at the connection position of the first hole section 211 and the second hole section 212. The parting surface 213 can further reduce the air velocity and the air volume of the air flow in the air diffusing hole 21, and further realize the non-wind feeling effect. In addition, the parting surface 213 is arranged to facilitate the molding of the air dispersing hole 21 and simplify the structure.
Further, as shown in fig. 3, the first hole section 211 gradually shrinks along the air outlet direction, and the second hole section 212 gradually enlarges along the air outlet direction. In other words, in the air outlet direction, the aperture of the first hole section 211 is gradually reduced, and the aperture of the second hole section 212 is gradually increased, so that the air volume of the airflow can be gradually reduced in the first hole section 211, and the flow speed of the airflow can be gradually reduced in the second hole section 212, which is beneficial to realizing the no-wind effect.
Alternatively, referring to fig. 3, the parting plane 213 may be a plane. Therefore, the structure can be simplified, the processing and the manufacturing are convenient, and the effects of reducing the air quantity and the air speed are achieved.
In some embodiments, as shown in fig. 2, the inlet area of the air dispersing holes 21 is not larger than the outlet area, that is, the inlet area of the air dispersing holes 21 may be equal to the outlet area, and the inlet area of the air dispersing holes 21 may be smaller than the outlet area. Therefore, the outlet air speed of the air dispersing holes 21 is not larger than the inlet air speed, and the outlet air speed of the air dispersing holes 21 is smaller than the inlet air speed, so that the air quantity and the air speed can be reduced, and the air outlet is free of wind feeling.
Of course, the present invention is not limited thereto, and the inlet area of the air dispersing holes 21 may be larger than the outlet area. So as to reduce the air output of the outlet.
In some embodiments, as shown in FIG. 3, the parting plane 213 of the diffuser holes 21 is spaced from the outlet end by no more than one-half of the total length of the diffuser holes 21. This can further contribute to the achievement of the no-wind effect.
In some embodiments, as shown in fig. 8 and 9, at least a portion of the plurality of air dispersing holes 21 has a hole diameter that decreases, increases, or remains constant in the top-down direction. That is, in the direction from top to bottom, the aperture of at least a part of the plurality of air-dispersing holes 21 on the outer air guiding plate 2 may decrease gradually, may increase gradually, and may be uniform, that is, the aperture may be kept constant. Therefore, the apertures of the outer air guide plate 2 at different positions can be set according to different air outlet requirements, and the applicability is improved.
In some embodiments, as shown in fig. 8 and 9, at least a portion of the plurality of air dispersing holes 21 may be arranged along a predetermined straight line, and at least a portion of the plurality of air dispersing holes 21 may be arranged in sequence along a predetermined curve. Therefore, the positions of the air dispersing holes 21 can be reasonably arranged according to requirements, and meanwhile, the appearance is beautified.
For example, a plurality of rows of air diffusing hole groups are arranged on the outer air guiding plate 2 at intervals along the length direction (for example, the left-right direction shown in fig. 8), and each row of air diffusing hole group comprises a plurality of air diffusing holes 21 arranged at intervals along the up-down direction. Wherein, a plurality of the air dispersing holes 21 in two adjacent rows of air dispersing hole groups are arranged in a staggered way along the vertical direction. In addition, the plurality of air dispersing holes 21 in two adjacent rows of air dispersing hole groups can also be arranged in left-right alignment.
As shown in fig. 8 and 9, the air dispersing holes 21 are formed in a plurality of rows arranged in the width direction of the outer air guide plate 2 and the plurality of rows are arranged in different densities in the width direction of the outer air guide plate 2. Specifically, the density of the air dispersing holes 21 below the outer air guide plate 2 is greater than the density of the air dispersing holes 21 above the outer air guide plate 2, and the general air speed at the lower side of the air outlet is the highest, so that the density of the air dispersing holes 21 below the outer air guide plate 2 is set to be greater than the density of the air dispersing holes 21 above the outer air guide plate 2, so that the air outlet speed of the outer air guide plate 2 is more uniform.
In some embodiments of the invention, the plurality of louvers 21 are different. The plurality of air-dispersing holes 21 may have different shapes or different cross-sectional areas. For example, in order to ensure a uniform wind speed of the wind discharged from the outer wind guide plate 2, the cross-sectional area of the wind dispersing holes 21 at the lower side of the outer wind guide plate 2 may be configured to be smaller than the cross-sectional area of the wind dispersing holes 21 at the upper side of the outer wind guide plate 2. Similarly, in order to ensure a uniform wind speed of the wind discharged from the outer wind guide plate 2, the shape of the wind dispersing holes 21 on the lower side of the outer wind guide plate 2 may be configured to be a shape that can more effectively reduce the wind speed with respect to the shape of the wind dispersing holes 21 on the upper side of the outer wind guide plate 2.
Wherein, changing the size of the aperture of the air dispersing hole 21 can change the air outlet speed and the air outlet quantity, which is beneficial to realizing the effect of no wind feeling. Therefore, in some embodiments, the aperture of the air dispersing hole 21 is in the range of 2mm to 4mm, thereby effectively reducing the wind speed and the wind volume while ensuring the cooling and heating rate.
As shown in fig. 2, in some embodiments, when the outer wind deflector 2 is perpendicular to the wind outlet direction, the included angle between the center line of the wind dispersing hole 21 and the horizontal plane is in the range of-10 ° to 10 °. Preferably, when the outer wind deflector 2 is perpendicular to the wind outlet direction, the included angle between the central line of the wind dispersing hole 21 and the horizontal plane is in the range of-5 degrees to 5 degrees. Preferably, when the outer wind deflector 2 is perpendicular to the wind outlet direction, the central line of the wind dispersing hole 21 is substantially parallel to the horizontal plane. Therefore, the airflow can be blown out along the direction which is approximately horizontal, the airflow is prevented from being directly blown to the human body, and the user experience is improved.
In some embodiments, the inner air guiding plate 3 is made of at least one material selected from the group consisting of normal ABS (acrylonitrile-styrene-butadiene copolymer), modified ABS, PC (polycarbonate), and modified PC.
In some embodiments, the outer air deflection plates 2 are made of at least one material of normal ABS (acrylonitrile-styrene-butadiene copolymer), modified ABS, PC (polycarbonate), and modified PC.
