As shown in fig. 7, when the inner air guiding plate 3 is in the second open state, the inner air guiding plate 3 extends into the air outlet 11 and is disposed along the air outlet direction (i.e. the inner air guiding plate 3 is substantially parallel to the air outlet direction), at this time, the air flow can be directly blown out through the air outlet 11, and the indoor air conditioning unit 100 is in a wind sensing mode, i.e. the indoor air conditioning unit 100 directly blows out hot air or cold air, so as to achieve the purpose of adjusting the indoor temperature.

In the process, the inner air guide plate 3 and the outer air guide plate 2 both have a blocking effect on the blown air flow, so that the air speed and the air quantity can be remarkably reduced, and the effect of no wind feeling is realized.
According to the air conditioning indoor unit 100 of the embodiment of the present invention, the first air dispersing holes 21 and the air dispersing holes are provided in the outer air guide plate 2 and the inner air guide plate 3, so that the air speed and the air volume of the air outlet 11 can be reduced, and the effects of a breeze sensation and a no-breeze sensation can be achieved. Realize the switching of multiple wind sense mode, promote user experience.
The outer air guiding plate 2 will be further described with reference to the accompanying drawings.
In one embodiment of the present invention, the sum of the areas of the first 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, it should be noted that the total area of the outer wind guide plate 2 includes the area of the first wind dispersing holes 21 on the outer wind guide plate 2.
In some embodiments of the present invention, referring to fig. 3, the first dispersing hole 21 may include a first hole section and a second hole section, which are sequentially connected in the wind outlet direction, and an outlet size of the first hole section is smaller than an inlet size of the second hole section, so that a parting plane is formed at a connection position of the first hole section and the second hole section. The parting surface can further reduce the air speed and the air volume of the air flow in the first air dispersing hole 21, and further realize the no-wind effect. In addition, the arrangement of the parting surface is convenient for the molding of the first air dispersing hole 21, and the structure is simplified.
Further, the first hole section of the first air dispersing hole 21 gradually shrinks along the air outlet direction, and the second hole section gradually enlarges along the air outlet direction. In other words, in the air outlet direction, the aperture of the first hole section is gradually reduced, and the aperture of the second hole section is gradually increased, so that the air volume of the air flow can be gradually reduced in the first hole section, and the flow speed of the air flow can be gradually reduced in the second hole section, thereby being beneficial to realizing the no-wind effect. Alternatively, referring to fig. 3, the parting plane may be planar. 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 first dispersion holes 21 is not larger than the outlet area, that is, the inlet area of the first dispersion holes 21 may be equal to the outlet area, and the inlet area of the first dispersion holes 21 may be smaller than the outlet area. Therefore, the outlet air speed of the first air dispersing holes 21 can be enabled to be not larger than the inlet air speed, and the outlet air speed of the first air dispersing holes 21 is enabled to be smaller than the inlet air speed, so that the air quantity and the air speed can be reduced, and the effect that the air is discharged without wind feeling is achieved. Of course, the present invention is not limited thereto, and the inlet area of the first air dispersing holes 21 may be larger than the outlet area. So as to reduce the air output of the outlet.
In some embodiments, the separation of the parting plane of the first louvers 21 from the outlet end is no more than one-half of the total length of the first louvers 21. This can further contribute to the achievement of the no-wind effect.
In some embodiments, as shown in fig. 10 and 11, at least a portion of the first air dispersing holes 21 have 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 first air dispersing holes 21 on the outer air guiding plate 2 may decrease sequentially, may also increase sequentially, and may also be uniform, that is, the aperture remains unchanged. 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. 10 and 11, at least a portion of the plurality of first air dispersing holes 21 may be arranged along a predetermined straight line, and at least a portion of the plurality of first air dispersing holes 21 may be arranged sequentially along a predetermined curve. Therefore, the positions of the first air dispersing holes 21 can be reasonably arranged according to requirements, and meanwhile, the appearance is beautified.
For example, a plurality of rows of first air dispersing 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. 10), and each row of first air dispersing hole group comprises a plurality of first air dispersing holes 21 arranged at intervals along the up-down direction. Wherein, a plurality of first air dispersing holes 21 in two adjacent rows of first air dispersing hole groups are staggered along the up-down direction. In addition, the plurality of first air dispersing holes 21 in the two adjacent rows of first air dispersing hole groups may be arranged in a left-right alignment.
It should be noted that, changing the aperture of the first air dispersing hole 21 can change the air outlet speed and the air outlet volume, which is beneficial to achieving the effect of no wind sensation. Therefore, in some embodiments, the aperture of the first air dispersing hole 21 is in the range of 2mm to 4mm, so that the wind speed and the wind volume can be effectively reduced, and the cooling and heating rate can be ensured.
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 first 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 center line of the first wind dispersing hole 21 and the horizontal plane is in the range of-5 ° to 5 °. Preferably, when the outer wind deflector 2 is perpendicular to the wind outlet direction, the center line of the first 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 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.
The inner air guiding plate 3 is further described below with reference to the drawings.
In some embodiments of the present invention, the sum of the areas of the plurality of second air dispersing holes 31 on the inner air guiding plate 3 is not less than 50% of the total area of the inner air guiding plate 3. 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, when the total area of the inner wind deflectors is too small, the effect of reducing the wind speed and the wind volume of the outlet 11 is not good, and therefore, it is preferable that the total area of the inner wind deflectors 3 is not less than 45% of the area of the outlet 11 in one embodiment of the present invention. Therefore, the air outlet speed and the air outlet quantity can be effectively reduced when the inner air guide plate is perpendicular to the air outlet direction, and the effect of no wind feeling is achieved. For example, the total area of the inner air deflectors 3 may be greater than 55%, 65%, 75%, or the like, of the area of the air outlet 11.
Here, the total area of the inner air guiding plate 3 includes the area of the second air dispersing holes 31 in the inner air guiding plate 3.
In some embodiments of the present invention, the projected area of the inner air deflector 3 along the thickness direction thereof is not less than 70% of the total area of the outlet 11. From this, interior aviation baffle 3 can effectively block the air-out amount of wind and the air-out wind speed of air outlet 11, realizes the effect of no wind sense, improves user experience. For example, the projection area of the inner air deflector 3 along the thickness direction thereof may be 80%, 85%, or 90% of the total area of the air outlet 11, and so on.
In some embodiments of the present invention, as shown in fig. 3, the second dispersing hole 31 may include a first hole section 311 and a second hole section 312, the first hole section 311 and the second hole section 312 are sequentially connected along the wind outlet direction, and an outlet size of the first hole section 311 is smaller than an inlet size of the second hole section 312, so that a parting plane 313 is formed at a connection position of the first hole section 311 and the second hole section 312. The parting surface 313 can further reduce the wind speed and the wind volume of the airflow in the second air dispersing hole 31, and further achieve the no-wind effect. In addition, the parting surface 313 is arranged, so that the second air dispersing hole 31 is convenient to mold, and the structure is simplified.
Further, as shown in fig. 3, the first hole section 311 gradually shrinks along the air outlet direction, and the second hole section 312 gradually enlarges along the air outlet direction. In other words, in the air outlet direction, the aperture of the first hole section 311 is gradually reduced, and the aperture of the second hole section 312 is gradually increased, so that the air volume of the airflow can be gradually reduced in the first hole section 311, and the flow speed of the airflow can be gradually reduced in the second hole section 312, which is beneficial to realizing the no-wind effect.
Alternatively, referring to fig. 3, the parting surface 313 in the second air dispersing hole 31 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, the inlet area of the second dissipating holes 31 is not greater than the outlet area, that is, the inlet area of the second dissipating holes 31 may be equal to the outlet area, and the inlet area of the second dissipating holes 31 may be smaller than the outlet area. Therefore, the outlet air speed of the second air dispersing holes 31 can be enabled to be not larger than the inlet air speed, and the outlet air speed of the second air dispersing holes 31 is enabled to be smaller than the inlet air speed, so that the air quantity and the air speed can be reduced, and the effect that the air is discharged without wind feeling is achieved.
Of course, the present invention is not limited thereto, and the inlet area of the second air dispersing holes 31 may be larger than the outlet area. So as to reduce the air output of the outlet.
In some embodiments, the parting plane 313 of the second louvers 31 is spaced from the outlet end by no more than one-half of the total length of the second louvers 31. This can further contribute to the achievement of the no-wind effect.
In some embodiments, as shown in fig. 12 and 13, at least a portion of the plurality of second air dispersing holes 31 have 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 second air dispersing holes 31 in the inner air guiding plate 3 may decrease gradually, may increase gradually, and may be uniform, that is, the aperture may be constant. Therefore, the apertures of the inner air guide plate 3 at different positions can be set according to different air outlet requirements, and the applicability is improved.
In some embodiments, at least a portion of the plurality of second dissipating holes 31 may be arranged along a predetermined straight line, and at least a portion of the plurality of second dissipating holes 31 may be arranged in sequence along a predetermined curved line. Therefore, the positions of the second air dispersing holes 31 can be reasonably arranged according to requirements, and meanwhile, the appearance is beautified.
For example, a plurality of rows of second air dispersing hole groups are arranged on the inner air guiding plate 3 at intervals along the length direction (for example, the left-right direction shown in fig. 13), and each row of second air dispersing hole group includes a plurality of second air dispersing holes 31 arranged at intervals along the up-down direction. Wherein, a plurality of second air dispersing holes 31 in two adjacent columns of second air dispersing hole groups are staggered along the up-down direction. In addition, the plurality of second air dispersing holes 31 in the two adjacent rows of second air dispersing hole groups may be arranged in a left-right alignment.
The size of the aperture of the second air dispersing hole 31 is changed to change the air outlet speed and the air outlet volume, which is beneficial to achieving the effect of no wind sensation. Therefore, in some embodiments, the aperture of the second air dispersing holes 31 is in the range of 4mm to 8mm, so that the wind speed and the wind volume can be effectively reduced, and the cooling and heating rates can be ensured.
In some embodiments, as shown in fig. 2, when the inner wind deflector 3 is perpendicular to the wind outlet direction, the included angle between the center line of the second wind dispersing hole 31 and the horizontal plane is in the range of-10 ° to 10 °. Preferably, when the inner air guiding plate 3 is perpendicular to the air outlet direction, the included angle between the center line of the second air dispersing hole 31 and the horizontal plane is in the range of-5 ° to 5 °. Preferably, when the inner wind deflector 3 is perpendicular to the wind outlet direction, the center line of the second wind dispersing hole 31 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.
The operation of the indoor unit 100 of an air conditioner according to the embodiment of the present invention will be described.
The air-conditioning indoor unit 100 of the embodiment of the present invention has a no-wind-sensation mode, a first breeze-sensation mode, a second breeze-sensation mode, a cooling wind-sensation mode, and a heating wind-sensation mode, and when the air-conditioning indoor unit 100 is in operation:
starting the indoor unit 100 of the air conditioner and selecting an air outlet mode;
when the first breeze sensing mode is selected, the outer air deflector 2 opens the air outlet 11, and the inner air deflector 3 rotates to be substantially vertical to the air outlet direction, as shown in fig. 8 and 9;
when the second breeze sensing mode is selected, the outer air deflector 2 closes the air outlet 11, and the inner air deflector 3 rotates to be substantially parallel to the air outlet direction, as shown in fig. 4 and 5;
when the no-wind mode is selected, the outer air deflector 2 is turned to a closed state (the air outlet 11 is closed), and the inner air deflector 3 is rotated to a position vertical to the air outlet direction, as shown in fig. 1 and 2;
when the cooling air-conditioning mode or the heating air-conditioning mode is selected, the outer air deflector 2 opens the air outlet 11, and the inner air deflector 3 rotates to be substantially parallel to the air outlet direction, as shown in fig. 6 and 7.
In the first breeze sensation mode, the inner air guide plate 3 is rotated to a position perpendicular to the wind speed, and the wind in the machine body 1 is blown out from the plurality of second wind dispersing holes 31, so that the wind speed is reduced, but the breeze sensation still exists because the aperture of the second wind dispersing holes 31 is relatively large (the aperture of the second wind dispersing holes 31 is larger than that of the first wind dispersing holes 21), as shown in fig. 9.
In the second breeze induction mode, the outer air guiding plate 2 is rotated to the closed state, the wind in the machine body 1 is blown out from the plurality of first wind dispersing holes 21, the wind speed is reduced, and the breeze effect which is lighter than that in the first breeze induction mode can be realized because the aperture of the first wind dispersing holes 21 is smaller than that of the second wind dispersing holes 31, as shown in fig. 5.
In the no-wind-sense mode, the outer wind deflector 2 is rotated to the closed state, the inner wind deflector 3 is rotated to the position vertical to the wind speed, the wind in the machine body 1 sequentially passes through the plurality of second wind-dispersing holes 31 and the plurality of first wind-dispersing holes 21 to be blown out, the wind speed and the wind volume are reduced twice, and therefore the no-wind-sense effect is achieved, as shown in fig. 2.
