Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to an air conditioner. Background Technology

[0002] In related technologies, air conditioners with two air outlets, one on the left and one on the right, offer a wider airflow angle. However, during operation, the airflow after heat exchange is directed to the left and right sides, resulting in less airflow directly in front of the air conditioner and a poorer airflow experience for those directly in front. This leads to poorer temperature regulation in front of the air conditioner and less uniform indoor temperature. Therefore, this issue needs to be addressed. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this invention is to provide an air conditioner whose air guide grille includes a first grille portion and a second grille portion, wherein the first grille portion is located above the second grille portion. The first grille portion includes a plurality of first grille ribs spaced apart in a horizontal direction, with a first air guide channel defined between adjacent first grille ribs. The surface of the first grille ribs facing the first air guide channel is a first air guide surface. The second grille portion includes a plurality of second grille ribs spaced apart in a horizontal direction, with a second air guide channel defined between adjacent second grille ribs. The surface of the second grille ribs facing the second air guide channel is a second air guide surface. By making the first air guide surface and the base... The angle α between the guide plane and the reference plane is smaller than the angle β between the second guide plane and the reference plane. Compared with the air blown out by the second air outlet area, the air blown out by the first air outlet area, which is located slightly above the air conditioner, can be closer to the front center of the air conditioner. This can effectively regulate the temperature directly in front of the unit and enhance the uniformity of the indoor temperature. The higher air outlet position of the first air outlet area can also reduce the discomfort caused by direct airflow, thereby improving the user experience. Furthermore, compared with the air blown out by the first air outlet area, the air blown out by the second air outlet area, which is located slightly below the air conditioner, can be closer to the left and right sides of the air conditioner. This can effectively reduce the discomfort caused by direct airflow, thereby improving the user experience.

[0004] In addition, by cooperating with the first and second air guide surfaces, the airflow in the first and second air outlet areas blows in different directions, which can make the air outlet of the air conditioner more comfortable and enhance the uniformity of indoor temperature.

[0005] An air conditioner according to an embodiment of the present invention includes: a casing component having an air inlet and two air outlets, the two air outlets being located at the left and right ends of the casing component respectively; the casing component having two air outlet channels arranged in a left-right direction, the two air outlet channels corresponding to the two air outlets respectively; each air outlet being located at the air outlet end of the corresponding air outlet channel; each air outlet extending in a vertical direction and including a first air outlet area, a second air outlet area, and a third air outlet area arranged sequentially from top to bottom; a heat exchanger assembly and a fan assembly disposed within the casing component; and an air guide grille disposed in the casing component and located at the air outlets, the air guide grille including a first grille section, a second grille section, and a third grille section arranged sequentially from top to bottom, the first grille section being located in the first air outlet area, the second grille section being located in the second air outlet area, and the third grille section being located in the third air outlet area; the first grille section including a plurality of first grille ribs spaced apart in a horizontal direction, adjacent to the first grille ribs... A first flow channel is defined between the grid ribs. The surface of the first grid rib facing the first flow channel is a first flow surface. The second grid portion includes a plurality of second grid ribs spaced apart in the horizontal direction. A second flow channel is defined between adjacent second grid ribs. The surface of the second grid rib facing the second flow channel is a second flow surface. The angle between the first flow surface and the reference surface is α, and the angle between the second flow surface and the reference surface is β, where α is less than β. The reference surface passes through the longitudinal central axis of the housing component and is perpendicular to the left-right direction. The longitudinal central axis of the housing component extends in the up-down direction. When the setting surface extends obliquely away from the reference surface in the direction from back to front, the angle between the setting surface and the reference surface is positive. When the setting surface extends obliquely towards the reference surface in the direction from back to front, the angle between the setting surface and the reference surface is negative. The setting surface includes the first flow surface and the second flow surface.

The surface of the second grille rib facing the second air guide channel is a second air guide surface. By clamping the first air guide surface with a reference surface... Angle α is smaller than the angle β between the second air guide surface and the reference surface. Compared to the air blown out by the second air outlet area, the air blown out by the first air outlet area, which is located slightly above the air conditioner, can be closer to the front center of the air conditioner.

[0050] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0051] The following is for reference. Figures 1-14 An air conditioner 100 according to an embodiment of the present invention is described.

[0052] Reference Figure 1 , Figure 3 , Figure 13 and Figure 14 According to an embodiment of the present invention, the air conditioner 100 includes a casing component 10, a heat exchanger assembly 20, a fan assembly 30, and an air guide grille 40. For example, the air conditioner 100 is a split-type air conditioner 100, which includes an indoor unit and an outdoor unit. For example, the air conditioner 100 can be a split-type floor-standing air conditioner 100, in which case the indoor unit can be a floor-standing indoor unit.

[0053] The housing component 10 has an air inlet 11 and two air outlets 12, which are located at the left and right ends of the housing component 10, respectively. One air outlet 12 is located at the left end of the housing, and the other air outlet 12 is located at the right end of the housing. The housing component 10 has two air outlet channels 131 arranged in the left-right direction. The two air outlet channels 131 correspond to the two air outlets 12, and each air outlet 12 is located at the air outlet end of the corresponding air outlet channel 131. Each air outlet 12 extends in the vertical direction and includes a first air outlet area 121, a second air outlet area 122, and a third air outlet area 123 arranged from top to bottom. The first air outlet area 121 is located above the second air outlet area 122, and the second air outlet area 122 is located above the third air outlet area 123. For example, the housing component 10 includes a first partition strip and a second partition strip arranged sequentially from top to bottom. Both the first and second partition strips are located at the air outlet 12. Both the first and second partition strips can extend horizontally. The air outlet area above the first partition strip of the air outlet 12 is the first air outlet area 121, the air outlet area below the first partition strip and above the second partition strip of the air outlet 12 is the second air outlet area 122, and the air outlet area below the second partition strip of the air outlet 12 is the third air outlet area 123. By setting the first and second partition strips at the air outlet 12, the air outlet 12 can be more easily divided into the first air outlet area 121, the second air outlet area 122, and the third air outlet area 123 arranged sequentially in the vertical direction. In addition, the first and second partition strips can also enhance the structural strength of the housing component 10, for example, they can enhance the structural strength near the air outlet 12 of the housing component 10 and reduce deformation.

[0054] The heat exchanger assembly 20 and the fan assembly 30 are disposed within the housing component 10, and the air guide grille 40 is disposed within the housing component 10 and located at the air outlet 12. For example, the housing component 10 of the air conditioner 100 includes a front housing component 1a and a rear housing component 1b. The front housing component 1a is connected to the front side of the rear housing component 1b. The front housing component 1a forms an air outlet 12, and the rear housing component 1b forms an air inlet 11. The heat exchanger assembly 20 is disposed within the housing component 10 and is located within the rear housing component 1b. The fan assembly 30 is disposed within the housing component 10 and is located between the heat exchanger assembly 20 and the air outlet 12.

[0055] When the air conditioner 100 is operating, the fan assembly 30 drives indoor air from the air inlet 11 into the casing component 10. After exchanging heat with the heat exchanger assembly 20, the air is blown out into the room through at least one of the two air outlets 12 to regulate the indoor temperature, for example, by lowering or raising the indoor temperature. As the airflow after heat exchange exits from the air outlet 12, it flows through the air guide grille 40, which can regulate the direction of the airflow passing through the air outlet 12.

[0056] The air guide grille 40 includes a first grille section 41, a second grille section 42, and a third grille section 43 arranged sequentially from top to bottom. The first grille section 41 is located in the first air outlet area 121, the second grille section 42 is located in the second air outlet area 122, and the third grille section 43 is located in the third air outlet area 123. The first grille section 41 corresponds to the first air outlet area 121, the second grille section 42 corresponds to the second air outlet area 122, and the third grille section 43 corresponds to the third air outlet area 123. The airflow blowing out from the first air outlet area 121 is guided by the first grille section 41, the airflow blowing out from the second air outlet area 122 is guided by the second grille section 42, and the airflow blowing out from the third air outlet area 123 is guided by the third grille section 43.

[0057] The first grille section 41 includes a plurality of first grille ribs spaced apart in a horizontal direction. A first guide channel 414 is defined between adjacent first grille ribs. The surface of the first grille rib facing the first guide channel 414 is a first guide surface 415. The airflow blown out from the first air outlet area 121 flows through the first guide channel 414 of the first grille section 41. During the flow through the first guide channel 414, the airflow is guided by the first guide surface 415 to adjust the airflow direction of the first air outlet area 121.

[0058] The second grille section 42 includes a plurality of second grille ribs spaced apart in a horizontal direction. A second guide channel 424 is defined between adjacent second grille ribs. The surface of the second grille ribs facing the second guide channel 424 is a second guide surface 425. The airflow blown out from the second air outlet area 122 flows through the second guide channel 424 of the second grille section 42. During the flow through the second guide channel 424, the airflow is guided by the second guide surface 425 to adjust the airflow direction of the second air outlet area 122.

[0059] The angle between the first guide surface 415 and the reference surface s is α, and the angle between the second guide surface 425 and the reference surface s is β, where α is less than β. The reference surface s passes through the longitudinal central axis of the housing component 10 and is perpendicular to the left-right direction. The longitudinal central axis of the housing component 10 extends in the up-down direction. When the setting surface extends obliquely away from the reference surface s in the direction from back to front, the angle between the setting surface and the reference surface s is positive. When the setting surface extends obliquely towards the reference surface s in the direction from back to front, the angle between the setting surface and the reference surface s is negative. The setting surface includes the first guide surface 415 and the second guide surface 425.

[0060] By making the angle α between the first airflow guide surface 415 and the reference surface s smaller than the angle β between the second airflow guide surface 425 and the reference surface s, the air blown out by the first airflow guide surface 121, which is slightly higher than the air blown out by the second airflow guide surface 122, can be closer to the front center of the air conditioner 100. This can effectively regulate the temperature in front of the air conditioner 100 and enhance the uniformity of the indoor temperature. The higher airflow position of the first airflow guide surface 121 can also reduce the discomfort caused by direct airflow, thereby improving the user experience. Furthermore, compared to the air blown out by the first airflow guide surface 121, the air blown out by the second airflow guide surface 122, which is slightly lower than the air conditioner 100, can be closer to the left and right sides of the air conditioner 100. This can effectively reduce the discomfort caused by direct airflow, thereby improving the user experience.

[0061] In addition, by cooperating with the first guide surface 415 and the second guide surface 425, the airflow of the first air outlet zone 121 and the second air outlet zone 122 blows in different directions, which can make the air outlet of the air conditioner 100 more comfortable and enhance the uniformity of indoor temperature.

[0062] Optionally, the air guide grille 40 can be a one-piece molded part, for example, the air guide grille 40 can be a one-piece injection molded part.

[0063] For example, the housing component 10 includes a first partition and a second partition, both of which are located at the air outlet 12. The air outlet area of ​​the air outlet 12 located above the first partition is the first air outlet area 121. The portion of the air guide grille 40 located above the first partition is the first grille portion 41. The air outlet area of ​​the air outlet 12 located below the first partition and above the second partition is the second air outlet area 122. The portion of the air guide grille 40 located below the first partition and above the second partition is the second grille portion 42. The air outlet area of ​​the air outlet 12 located below the second partition is the third air outlet area 123. The portion of the air guide grille 40 located below the second partition is the third grille portion 43. By setting the first partition and the second partition at the air outlet 12, the air guide grille 40 can be easily divided into the first grille portion 41, the second grille portion 42, and the third grille portion 43 arranged in the vertical direction.

[0064] For example, the divider can extend horizontally and be thickened vertically to reduce the appearance differences between the first grille section 41, the second grille section 42, and the third grille section 43.

[0065] For example, the partition strip also serves to support and connect. The first grid rib is connected to the upper side of the first partition strip, the second grid rib is connected to the lower side of the first partition strip and the upper side of the second partition strip, and the third grid rib is connected to the lower side of the second partition strip. By connecting the first, second, and third grid ribs to the partition strip, the air guide grille 40 can achieve higher structural strength and greater structural stability.

[0066] Optionally, the air conditioner 100 also includes an air guide plate 15, which is used to open and close the air outlet 12. The air guide plate 15 can guide the airflow flowing out of the air outlet 12. For example, the air guide plate 15 is rotatably disposed at the air outlet 12. By adjusting the rotation range of the air guide plate 15, the air outlet 12 can be opened or closed, and the direction of the airflow at the air outlet 12 can also be adjusted.

[0067] For example, multiple ventilation holes are formed on the air guide plate 15, which penetrate the air guide plate 15 along its thickness direction. The air conditioner 100 has a windless mode, in which the air guide plate 15 closes the air outlet 12. When the air conditioner 100 is in the windless mode, the air guide plate 15 is in the closed position, and the airflow enters the casing component 10 through the air inlet 11 and flows to the heat exchanger assembly 20. After heat exchange by the heat exchanger assembly 20, the airflow can be blown out through the ventilation holes on the air guide plate 15, making the airflow from the air outlet 12 gentler and thus improving the user experience.

[0068] In some embodiments, the housing component 10 of the air conditioner 100 includes an air outlet frame 13, on which an air outlet channel 131 is formed. The air outlet end of the air outlet channel 131 is connected to the air outlet 12. An air guide grille 40 is installed on the air outlet frame 13 and located at the air outlet end of the air outlet channel 131. For example, the air guide grille 40 can be integrally formed with the air outlet frame 13, which can enhance the overall structural strength of the air outlet frame 13 and eliminate the assembly process between the air guide grille 40 and the air outlet frame 13. Of course, the air guide grille 40 can also be detachably provided on the air outlet frame 13, which can facilitate the maintenance or replacement of the air guide grille 40.

[0069] In the description of this invention, "a plurality of" means two or more.

[0070] According to an embodiment of the air conditioner 100, the air guide grille 40 of the air conditioner 100 includes a first grille portion 41 and a second grille portion 42, wherein the first grille portion 41 is located above the second grille portion 42. The first grille portion 41 includes a plurality of first grille ribs spaced apart in a horizontal direction, and a first air guide channel 414 is defined between adjacent first grille ribs. The surface of the first grille rib facing the first air guide channel 414 is a first air guide surface 415. The second grille portion 42 includes a plurality of second grille ribs spaced apart in a horizontal direction, and a second air guide channel 424 is defined between adjacent second grille ribs. The surface of the second grille rib facing the second air guide channel 424 is a second air guide surface 425. By making the first air guide surface 415 and the second grille portion 425 form a first air guide surface 425, the air guide surface 425 is formed by the first air guide surface 415 and the second grille portion 424. The angle α between the reference plane s and the reference plane s is smaller than the angle β between the second guide surface 425 and the reference plane s. Compared with the air blown out by the second air outlet 122, the air blown out by the first air outlet 121, which is slightly higher than the air conditioner 100, can be closer to the front center of the air conditioner 100. This can effectively regulate the temperature directly in front of the unit and enhance the uniformity of the indoor temperature. The higher air outlet position of the first air outlet 121 can also reduce the discomfort caused by direct airflow, thereby improving the user experience. Furthermore, compared with the air blown out by the first air outlet 121, the air blown out by the second air outlet 122, which is slightly lower than the air conditioner 100, can be closer to the left and right sides of the air conditioner 100. This can effectively reduce the discomfort caused by direct airflow, thereby improving the user experience.

[0071] In addition, by cooperating with the first guide surface 415 and the second guide surface 425, the airflow of the first air outlet zone 121 and the second air outlet zone 122 blows in different directions, which can make the air outlet of the air conditioner 100 more comfortable and enhance the uniformity of indoor temperature.

[0072] Reference Figure 4 and Figure 8 According to some embodiments of the present invention, α is a positive value and the value of α ranges from 10° to 25°. For example, the value of α can be 10°, 14°, 18°, 23°, 25°, etc. By ensuring that the value of α is not less than 10°, the air blown out of the first air outlet zone 121 can be prevented from being too concentrated in front of the whole unit; by ensuring that the value of α is not greater than 25°, the air volume blown out of the first air outlet zone 121 towards the front of the whole unit can be sufficient to effectively regulate the temperature in front of the air conditioner 100.

[0073] By ensuring that α is positive and its range is 10° to 25°, the air blown out of the first air outlet zone 121 can be prevented from being too concentrated in front of the whole unit, and the air volume in front of the whole unit can be sufficient.

[0074] Reference Figure 4 and Figure 8According to some embodiments of the present invention, the difference between β and α ranges from 10° to 30°. For example, the difference between β and α can be 10°, 15°, 20°, 25°, 30°, etc. By ensuring that the difference between β and α is not less than 10°, the direction of the air blown from the first air outlet zone 121 is significantly different from the direction of the air blown from the second air outlet zone 122, so that the air blown from the first air outlet zone 121 can effectively regulate the temperature in front of the air conditioner 100, and reduce or avoid discomfort caused by the air blown from the second air outlet zone 122 blowing directly on the user located in front of the unit; by ensuring that the difference between β and α is not greater than 30°, the difference in the air outlet direction between the first air outlet zone 121 and the second air outlet zone 122 is avoided from being too large, thereby making the temperature distribution in the room more uniform.

[0075] Reference Figure 7 and Figure 8 According to some embodiments of the present invention, the housing component 10 includes a front panel 14, which is located between two air outlets 12. The side wall of the air outlet duct 131 near the front panel 14 is a first side wall 132. The setting surface includes the first side wall 132. The angle between the first side wall 132 and the reference surface s is γ, where β and γ are both positive values, and γ+5°≤β≤γ+25°. For example, the value of β can be γ+5°, γ+10°, γ+15°, γ+20°, γ+25°, etc. By ensuring that β is not less than γ+5°, the air blown out by the second air outlet 122 can be directed towards the left and right sides of the air conditioner 100, thereby reducing or avoiding discomfort caused by the air blown out by the second air outlet 122 directly blowing on the user located in front of the air conditioner 100. By ensuring that β is not greater than γ+25°, the air blown out by the second air outlet 122 can be prevented from being too concentrated on the left and right sides of the air conditioner 100, or even flowing backward, thus weakening the temperature regulation effect on the front of the air conditioner 100.

[0076] By using γ+5°≤β≤γ+25°, the discomfort caused by the air blown directly from the second air outlet 122 to the user located directly in front of the air conditioner 100 can be reduced or avoided. It can also prevent the air blown from the second air outlet 122 from being too concentrated on the left and right sides of the air conditioner 100, or even flowing backward, thus weakening the temperature regulation effect on the front of the air conditioner 100.

[0077] Reference Figure 7 and Figure 8According to some embodiments of the present invention, the housing component 10 includes a front panel 14 located between two air outlets 12. The side wall of the air outlet duct 131 near the front panel 14 is a first side wall 132. The angle between the second guide surface 425 on the second grille rib furthest from the first side wall 132 in the same second air outlet area 122 and the reference plane s is a first angle β1. The angle between the second guide surface 425 on the remaining second grille ribs and the reference plane s is a second angle β2. The first angle β1 is smaller than the second angle β2. By making the first included angle β1 smaller than the second included angle β2, compared with the airflow guiding direction of the other second grille ribs in the same second air outlet area 122, the second grille rib furthest from the first side wall 132 in the same second air outlet area 122 can adjust the airflow guiding direction of the second air outlet area 122 furthest from the first side wall 132 to be biased towards the front. This can reduce or avoid the airflow blown out by the second guide surface 425 of the second grille rib furthest from the first side wall 132 being too biased towards the left and right sides of the air conditioner 100, thereby reducing or avoiding the possibility of the airflow in the second air outlet area 122 flowing towards the rear of the air conditioner 100, thus ensuring the temperature regulation effect of the air conditioner 100 on the front.

[0078] Reference Figures 3-6 According to some embodiments of the present invention, the width of the first grille rib is 10mm to 30mm. For example, the width of the first grille rib can be 10mm, 15mm, 20mm, 25mm, 30mm, etc. By ensuring that the width of the first grille rib is not less than 10mm, the width of the first grille rib can be sufficiently long, thereby improving the airflow guiding effect of the first grille rib and improving the temperature regulation effect at the upper part in front of the air conditioner 100. It can also give the first grille rib strong structural strength. By ensuring that the width of the first grille rib is not greater than 30mm, while effectively regulating the airflow direction, the obstruction area of ​​the first grille rib on the airflow cross-section can be reduced, thereby reducing airflow resistance and airflow loss.

[0079] By using a first grille rib width of 10mm to 30mm, the airflow guiding effect of the first grille rib and the air volume loss can be better balanced.

[0080] Reference Figures 7-9According to some embodiments of the present invention, the width of the second grille rib is 8mm to 15mm. For example, the width of the second grille rib can be 8mm, 10mm, 12mm, 14mm, 15mm, etc. By ensuring that the width of the second grille rib is not less than 8mm, the width of the second grille rib can be sufficiently long, thereby improving the airflow guiding effect of the second grille rib and effectively reducing the discomfort caused by the direct blowing of the air from the second air outlet 122. It can also give the second grille rib strong structural strength. By ensuring that the width of the second grille rib is not greater than 15mm, the area of ​​airflow obstruction caused by the second grille rib on the airflow cross section can be reduced, thereby reducing the flow resistance and airflow loss.

[0081] By using a second grille rib with a width of 8mm to 15mm, the airflow guiding effect and air volume loss of the second grille rib can be better balanced.

[0082] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8 According to some embodiments of the present invention, the width of the first grille rib is 10mm to 30mm; and the width of the second grille rib is 8mm to 15mm, which can better balance the air guiding effect and air volume loss of the first grille rib and the second grille rib in the corresponding air outlet area.

[0083] Reference Figures 3-6 According to some embodiments of the present invention, the housing component 10 includes a front panel 14 located between two air outlets 12. The air outlet channel 131 includes a first side wall 132 and a second side wall 133 arranged opposite each other in a horizontal direction. The first side wall 132 is closer to the front panel 14 than the second side wall 133. A plurality of first grille ribs are divided into multiple groups of first grille ribs. Each group of first grille ribs includes at least one first grille rib. The multiple groups of first grille ribs are arranged sequentially in the direction from the first side wall 132 to the second side wall 133. The width of the group of first grille ribs that is closer to the first side wall 132 in two adjacent groups of first grille ribs is less than or equal to the width of the other group of first grille ribs in two adjacent groups of first grille ribs. The width of the first grille rib refers to the width of the first grille rib in the air outlet direction of the corresponding first air outlet area 121. For example, the width of the first grid ribs that are relatively closer to the first side wall 132 in two adjacent groups of first grid ribs can be less than the width of the other group of first grid ribs in two adjacent groups of first grid ribs; as another example, the width of the first grid ribs that are relatively closer to the first side wall 132 in two adjacent groups of first grid ribs can also be equal to the width of the other group of first grid ribs in two adjacent groups of first grid ribs.

[0084] Since the airflow that is relatively far from the first side wall 132 is closer to the left and right sides of the air conditioner 100 in the flow cross section, by making the width of the first grille rib that is relatively close to the first side wall 132 in two adjacent sets of first grille ribs less than or equal to the width of the other set of first grille ribs in two adjacent sets of first grille ribs, the other first grille rib that is relatively far from the first side wall 132 in two adjacent sets of first grille ribs can have a stronger air guiding effect. This can effectively adjust the guiding effect of the airflow that is relatively far from the first side wall 132, so that the airflow that is relatively far from the first side wall 132 is directed as far as possible toward the front of the unit, thereby effectively regulating the temperature in front of the air conditioner 100.

[0085] Reference Figures 3-6 According to some embodiments of the present invention, in the direction from the first side wall 132 to the second side wall 133, multiple groups of first grid ribs are respectively first grid rib group one 411, first grid rib group two 412, and first grid rib group three 413. The width of the first grid rib in first grid rib group one 411 is P1, the width of the first grid rib in first grid rib group two 412 is P2, and the width of the first grid rib in first grid rib group three 413 is P3, where P1 < P2 ≤ P3.

[0086] Because the first grid rib in the first grid rib group 1 411 is closer to the first side wall 132, and the first grid rib in the first grid rib group 3 413 is closer to the second side wall 133, by using P1 < P2 ≤ P3, the width of the first grid rib in the first grid rib group 1 411 can be smaller than the width of the first grid rib in the first grid rib group 2 412, and the width of the first grid rib in the first grid rib group 2 412 can be less than or equal to the width of the first grid rib in the first grid rib group 3 413. The first grille ribs in the first grille rib group 1, which are relatively close to the first side wall 132, can make the first grille ribs in the first grille rib group 2 412 and the first grille rib group 3 413, which are relatively far away from the first side wall 132, have a stronger air guiding effect. This can effectively adjust the flow direction of the airflow that is relatively far away from the first side wall 132, so that the airflow that is relatively far away from the first side wall 132 is as far as possible towards the front of the whole unit with a sufficient air volume, so as to effectively regulate the temperature in front of the air conditioner 100.

[0087] Reference Figures 3-6According to some embodiments of the present invention, 10mm≤P1≤15mm, 12mm≤P2≤30mm, and 15≤P3≤30mm. For example, the value of P1 can be 10mm, 12mm, 13mm, 14mm, 15mm, etc.; the value of P2 can be 12mm, 15mm, 20mm, 25mm, 30mm, etc.; and the value of P3 can be 15mm, 20mm, 23mm, 27mm, 30mm, etc.

[0088] Because the first grille rib in the first grille rib group is closer to the front panel 14, and the width P1 of the first grille rib in the first grille rib group 411 is not less than 10mm and not more than 15mm, the first grille rib in the first grille rib group 411 has strong structural strength and can reduce the area of ​​airflow obstruction on the airflow cross section, thereby reducing the airflow loss in the first air outlet area 121 and making the airflow towards the central front part of the whole unit more sufficient. Because the width P2 of the first grille rib in the second grille rib group 412 is not less than 12mm and not more than 30mm, the first grille rib in the second grille rib group 412 has strong structural strength and, compared to the first grille rib in the first grille rib group 411, the first grille rib in the second grille rib group 412 has a stronger guiding effect, causing the airflow direction passing through the first grille rib in the second grille rib group 412 to flow as far towards the central front part of the whole unit as possible.

[0089] Because the airflow passing through the first grille ribs in the first grille rib group 3 413 is closer to the left and right sides of the air conditioner 100, and the first grille ribs in the first grille rib group 3 413 are larger than 15mm, the air guiding effect of the first grille ribs in the first grille rib group 3 413 can be greater, so as to more effectively adjust the airflow direction and make the airflow flow towards the front center of the whole unit, so as to effectively regulate the temperature at the front of the whole unit. Furthermore, the first grille ribs in the first grille rib group 3 413 are smaller than 30mm, so as to reduce the area of ​​the first grille ribs in the first grille rib group 3 413 that blocks the airflow in the airflow cross section, thereby reducing the impact of the first grille ribs in the first grille rib group 3 413 on the airflow loss.

[0090] Reference Figures 7-9According to some embodiments of the present invention, the housing component 10 includes a front panel 14 located between two air outlets 12. The air outlet channel 131 includes a first side wall 132 and a second side wall 133 arranged opposite each other in a horizontal direction, wherein the first side wall 132 is closer to the front panel 14 than the second side wall 133. A plurality of second grille ribs are divided into multiple groups of second grille ribs, each group of second grille ribs including at least one second grille rib. The multiple groups of second grille ribs are arranged sequentially in the direction from the first side wall 132 to the second side wall 133. The width of the group of second grille ribs that is closer to the first side wall 132 in two adjacent groups of second grille ribs is less than or equal to the width of the other group of second grille ribs in two adjacent groups of second grille ribs. The width of the second grille rib refers to the width of the second grille rib in the air outlet direction of the corresponding second air outlet area 122.

[0091] For example, the width of the second grid ribs that are relatively closer to the first side wall 132 in two adjacent groups of second grid ribs can be less than the width of the other group of second grid ribs in two adjacent groups of second grid ribs; as another example, the width of the second grid ribs that are relatively closer to the first side wall 132 in two adjacent groups of second grid ribs can also be equal to the width of the other group of second grid ribs in two adjacent groups of second grid ribs.

[0092] Since the airflow that is relatively far from the first side wall 132 is closer to the left and right sides of the air conditioner 100, by making the width of the second grille rib that is relatively close to the first side wall 132 in two adjacent sets of second grille ribs less than or equal to the width of the other set of second grille ribs in two adjacent sets of second grille ribs, the other second grille rib that is relatively far from the first side wall 132 in two adjacent sets of second grille ribs can have a stronger air guiding effect. This can effectively adjust the guiding effect of the airflow that is relatively far from the first side wall 132. This can reduce or avoid the airflow blown out by the second guide surface 425 of the second grille rib that is furthest from the first side wall 132 being too biased to the left and right sides of the air conditioner 100, thereby reducing or avoiding the possibility that the airflow in the second air outlet area 122 will flow toward the rear of the air conditioner 100, thus ensuring the temperature regulation effect of the air conditioner 100 on the front.

[0093] Reference Figures 7-9 According to some embodiments of the present invention, in the direction from the first side wall 132 to the second side wall 133, multiple sets of second grid ribs are respectively second grid rib group one 421, second grid rib group two 422, and second grid rib group three 423. The width of the second grid rib in second grid rib group one 421 is Q1, the width of the second grid rib in second grid rib group two 422 is Q2, and the width of the second grid rib in second grid rib group three 423 is Q3, where Q1 = Q2 ≤ Q3.

[0094] Because the second grid ribs in the first grid rib group 421 are closer to the first side wall 132, and the second grid ribs in the third grid rib group 423 are closer to the second side wall 133, by using Q1=Q2≤Q3, the width of the second grid ribs in the first grid rib group 421 can be equal to the width of the second grid ribs in the second grid rib group 422, and the widths of the second grid ribs in the first grid rib group 411 and the second grid ribs in the second grid rib group 422 are less than or equal to the width of the second grid ribs in the third grid rib group 423, compared to those relatively closer to the first side wall 132. The second grille ribs in the second grille rib group 1 and the second grille ribs in the second grille rib group 2 422 can make the second grille ribs in the second grille rib group 3 423 have a stronger air guiding effect, which can effectively adjust the flow direction of the airflow that is relatively far away from the first side wall 132. This can reduce or avoid the airflow blown out by the second guide surface 425 of the second grille rib that is furthest away from the first side wall 132 being too biased to the left and right sides of the air conditioner 100, thereby reducing or avoiding the possibility that the airflow in the second air outlet area 122 will flow towards the rear of the air conditioner 100, thus ensuring the temperature regulation effect of the air conditioner 100 on the front.

[0095] Reference Figures 3-6 According to some embodiments of the present invention, at least a portion of the first guide surface 415 is formed as a planar or arcuate surface. The formation of at least a portion of the first guide surface 415 as a planar or arcuate surface may include the following: for example, a portion of the first guide surface 415 may be formed as a planar or arcuate surface; or, for another example, the entire first guide surface 415 may be formed as a planar or arcuate surface.

[0096] For example, at least a portion of the first guide surface 415 is formed as a plane. By making at least a portion of the first guide surface 415 as a plane, the structure of the first grille rib is simple and easy to process and form. As another example, at least a portion of the first guide surface 415 is formed as an arc surface. By making at least a portion of the first guide surface 415 as an arc surface, the first guide surface 415 can have a better guide effect while reducing the impact of the first guide surface 415 on the air volume of the first air outlet zone 121.

[0097] Reference Figures 3-6 According to some embodiments of the present invention, at least a portion of the second guide surface 425 is formed as a planar or arcuate surface. The formation of at least a portion of the second guide surface 425 as a planar or arcuate surface may include the following: for example, a portion of the second guide surface 425 may be formed as a planar or arcuate surface; or, for another example, the entire second guide surface 425 may be formed as a planar or arcuate surface.

[0098] For example, at least a portion of the second guide surface 425 is formed as a plane. By making at least a portion of the second guide surface 425 as a plane, the structure of the second grille ribs is simple and easy to process and form. As another example, at least a portion of the second guide surface 425 is formed as an arc surface. By making at least a portion of the second guide surface 425 as an arc surface, the second guide surface 425 can have a better guide effect while reducing the impact of the second guide surface 425 on the air volume of the second air outlet zone 122.

[0099] Reference Figures 3-6 According to some embodiments of the present invention, at least a portion of the first guide surface 415 is formed as a planar or arc-shaped surface; and at least a portion of the second guide surface 425 is formed as a planar or arc-shaped surface. For example, at least a portion of the first guide surface 415 and the second guide surface 425 are formed as planar surfaces. By forming at least a portion of the first guide surface 415 and the second guide surface 425 as planar surfaces, the structure of the first grid ribs and the second grid ribs is simple and easy to process and form. As another example, at least a portion of the first guide surface 415 and the second guide surface 425 are formed as arc-shaped surfaces. By forming at least a portion of the first guide surface 415 and the second guide surface 425 as arc-shaped surfaces, the first guide surface 415 and the second guide surface 425 can have a better guide effect while reducing the influence of the first guide surface 415 on the first air outlet area 121 and the second guide surface 425 on the air outlet area 122.

[0100] Reference Figures 10-12 According to some embodiments of the present invention, the third grille portion 43 of the third air outlet zone 123 on the left side is the left third grille portion 431, and the third grille portion 43 of the third air outlet zone 123 on the right side is the right third grille portion 432. The left third grille portion 431 includes a plurality of left third grille ribs 4311 spaced apart in the horizontal direction. A left third guide channel 4312 is defined between adjacent left third grille ribs 4311, and the surface of the left third grille ribs 4311 facing the left third guide channel 4312 is the third guide surface 431. 3. The right third grille section 432 includes a plurality of right third grille ribs 4321 spaced apart in the horizontal direction. A right third flow channel 4322 is defined between adjacent right third grille ribs 4321. The surface of the right third grille ribs 4321 facing the right third flow channel 4322 is a fourth flow surface 4323. The angle between the third flow surface 4313 and the reference surface s is δ, and the angle between the fourth flow surface 4323 and the reference surface s is θ. The values ​​of δ and θ are different. The set surface includes the third flow surface 4313 and the fourth flow surface 4323.

[0101] The airflow from the third air outlet zone 123 on the left flows through the left third guide channel 4312 of the left third grille section 431. During its flow through the third guide channel, it is guided by the third guide surface 4313 to adjust the airflow direction of the third air outlet zone 123 on the left. Similarly, the airflow from the third air outlet zone 123 on the right flows through the right third guide channel 4322 of the right third grille section 432. During its flow through the third guide channel, it is guided by the fourth guide surface 4323 to adjust the airflow direction of the third air outlet zone 123 on the right. By making the angle δ between the third guide surface 4313 and the reference plane s different from the angle θ between the fourth guide surface 4323 and the reference plane s, the airflow directions on the left and right sides of the lower third air outlet zone 123 of the air conditioner 100 can be different, thus meeting different usage needs and improving the user experience.

[0102] For example, if δ is less than θ, the air blown from the third air outlet zone 123 located on the right side of the lower part of the air conditioner 100 can be closer to the right side of the air conditioner 100, preventing the air from blowing directly onto the legs and improving the user experience.

[0103] Reference Figures 10-12 According to some embodiments of the present invention, an air inlet temperature sensor is included, which is located in the third air outlet zone 123 on the left side, where δ is less than θ. By making the angle δ between the third guide surface 4313 and the reference surface s less than the angle θ between the fourth guide surface 4323 and the reference surface s, the air blown out from the third air outlet zone 123 located on the lower left side of the air conditioner 100 can be brought closer to the front center of the air conditioner 100, reducing or avoiding the airflow direction after heat exchange being too close to the left side of the air conditioner 100. This reduces the impact of the air blown out from the third air outlet zone 123 on the accuracy of the air inlet temperature measured by the air inlet temperature sensor.

[0104] Reference Figures 10-12 According to some embodiments of the present invention, δ is a positive value and the value range of δ is 10° to 25°. For example, the value of δ can be 10°, 13°, 18°, 22°, 25°, etc. By ensuring that the value of δ is not less than 10°, the air blown out by the third air outlet zone 123 on the left side can be concentrated too much in front of the whole unit, reducing the discomfort caused by direct airflow to users located directly in front of the air conditioner 100; by ensuring that the value of δ is not greater than 25°, the air blown out by the third air outlet zone 123 on the left side can be prevented from being too concentrated on the left side of the air conditioner 100, thereby reducing the impact of the air blown out by the third air outlet zone 123 on the accuracy of the inlet air temperature measured by the inlet air temperature sensor.

[0105] By setting the value of δ to a range of 10° to 25°, the discomfort caused by direct airflow to users located directly in front of the air conditioner 100 can be reduced, and the impact of the air blown out from the third air outlet zone 123 on the left side on the accuracy of the air inlet temperature measured by the air inlet temperature sensor can be reduced.

[0106] Reference Figures 10-12 According to some embodiments of the present invention, the difference between θ and δ ranges from 10° to 30°. For example, the difference between θ and δ can be 10°, 15°, 20°, 25°, 30°, etc. By ensuring that the difference between θ and δ is not less than 10°, the direction of the air blown from the third air outlet zone 123 on the left side is significantly different from the direction of the air blown from the third air outlet zone 123 on the right side. For example, the air blown from the third air outlet zone 123 on the left side is closer to the front center of the air conditioner 100, thereby reducing the impact of the air blown from the third air outlet zone 123 on the accuracy of the air inlet temperature measured by the air inlet temperature sensor, and making the air blown from the third air outlet zone 123 on the right side as far to the right as possible, thereby reducing the discomfort caused to the user by direct airflow. By ensuring that the difference between θ and δ is not greater than 30°, the difference in the air outlet direction between the third air outlet zone 123 on the left side and the third air outlet zone 123 on the right side is avoided, thereby making the indoor temperature distribution more uniform.

[0107] By using a difference between θ and δ ranging from 10° to 30°, the difference in airflow direction between the third air outlet zone 123 on the left and the third air outlet zone 123 on the right can be avoided. This also reduces the impact of the air blown out by the third air outlet zone 123 on the accuracy of the air inlet temperature measured by the air inlet temperature sensor, and reduces the discomfort caused by the air blown out by the third air outlet zone 123 on the user located in front of the air conditioner 100.

[0108] Reference Figures 10-12 According to some embodiments of the present invention, δ is a positive value and its value ranges from 10° to 25°; and the difference between θ and δ ranges from 10° to 30°. This can reduce the discomfort caused by direct airflow to users located directly in front of the air conditioner 100, and can reduce the influence of the air blown out by the third air outlet zone 123 on the accuracy of the air inlet temperature measured by the air inlet temperature sensor. It can also avoid excessive differences in the air outlet direction between the third air outlet zone 123 on the left and the third air outlet zone 123 on the right, thereby making the indoor temperature distribution more uniform.

[0109] Reference Figure 1 , Figure 13 and Figure 14According to some embodiments of the present invention, the distance between the lower edge of the air outlet 12 and the bottom surface of the housing component 10 in the vertical direction is H1, and the range of H1 is 0.35m to 0.6m. For example, the value of H1 can be 0.35m, 0.40m, 0.45m, 0.5m, 0.55m, 0.6m, etc. By ensuring that the value of H1 is not less than 0.35m, the area between the lower edge of the air outlet 12 and the bottom surface of the housing component 10 can have a larger space in the vertical direction, so that other components can be accommodated in this space. By ensuring that the value of H1 is not greater than 0.6m, other components can be avoided from being installed in the space between the lower edge of the air outlet 12 and the bottom surface of the housing component 10, thus limiting the size of the air outlet 12. This effectively utilizes the space of the housing component 10 in the vertical direction, making the size of the air outlet 12 larger in the vertical direction. As a result, the air outlet area of ​​the whole unit can be larger, which is beneficial to improving the cooling / heating effect of the air conditioner 100.

[0110] With H1 ranging from 0.35m to 0.6m, the area between the lower edge of the air outlet 12 and the bottom surface of the housing component 10 can have a large space in the vertical direction, so that other components can be accommodated in this space, and the size of the air outlet 12 in the vertical direction can be large, thereby making the air outlet area of ​​the whole unit larger.

[0111] Reference Figure 1 , Figure 13 and Figure 14 According to some embodiments of the present invention, the distance between the lower edge of the air outlet 12 and the bottom surface of the housing component 10 in the vertical direction is H1, and the height dimension of the third air outlet zone 123 in the vertical direction is H2, where 0.7m-H1≤H2≤1.0m-H1 or H2≤H1. For example, the value of H2 can be 0.7m-H1, 0.8m-H1, 0.85m-H1, 0.95m-H1, 1.0m-H1, etc., or H2 is less than H1. This allows the height dimension of the third air outlet zone 123 in the vertical direction to be larger, so that the air supply volume of the third air outlet zone 123 is larger. It also avoids the third air outlet zone 123 being too large in the vertical direction, which would limit the size of the first air outlet zone 121 and the second air outlet zone 122. This facilitates the air conditioner 100 to achieve different air supply effects in multiple areas in the vertical direction.

[0112] Reference Figure 1 , Figure 13 and Figure 14According to some embodiments of the present invention, the vertical distance between the lower edge of the air outlet 12 and the bottom surface of the housing component 10 is H1, the vertical height of the third air outlet area 123 is H2, and the vertical height of the second air outlet area 122 is H3, where 0.35*(H1+H2)≤H3≤0.7*(H1+H2). For example, the value of H3 can be 0.35*(H1+H2), 0.4*(H1+H2), 0.55*(H1+H2), 0.6*(H1+H2), 0.7*(H1+H2), etc. By ensuring that the value of H3 is not less than 0.35*(H1+H2), the air outlet area of ​​the second air outlet area 122 can be sufficiently large, allowing more air blown from the air conditioner 100 to be directed towards the left and right sides of the air conditioner 100, thus increasing the air volume of the air conditioner 100. While being large enough, it can effectively reduce the discomfort caused by the air blown directly from the second air outlet zone 122 located in the middle of the air conditioner 100 to the user in front of the air conditioner 100; by ensuring that the value of H3 is no greater than 0.7*(H1+H2), it can avoid the second air outlet zone 122 being too large in the vertical direction, which would limit the size of the first air outlet zone 121 and the third air outlet zone 123, thereby facilitating the air conditioner 100 to achieve different air supply effects in multiple areas in the vertical direction.

[0113] By ensuring that the value of H3 satisfies 0.35*(H1+H2)≤H3≤0.7*(H1+H2), the air volume of the second air outlet zone 122 located in the middle of the air conditioner 100 can be increased. This also prevents the height of the second air outlet zone 122 from being too large in the vertical direction, which would limit the size of the first air outlet zone 121 and the third air outlet zone 123. Consequently, the air conditioner 100 can achieve different air supply effects in multiple areas in the vertical direction.

[0114] Reference Figure 1 , Figure 13 and Figure 14 According to some embodiments of the present invention, the height dimension of the housing component 10 in the vertical direction is H, and the height dimension of the first air outlet zone 121 in the vertical direction is H4, where 0.15*H≤H4≤0.45*H. For example, the value of H4 can be 0.15H, 0.2H, 0.3H, 0.35H, or 0.45H. By ensuring that the value of H4 is not less than 0.15H, the air outlet area of ​​the first air outlet zone 121 can be large enough, allowing more air blown from the air conditioner 100 to be closer to the front center of the air conditioner 100, enabling the air conditioner 100 to more effectively regulate the temperature in front of the air conditioner 100. By ensuring that the value of H4 is not greater than 0.45H, the height dimension of the first air outlet zone 121 in the vertical direction is not too large, which would limit the size of the second air outlet zone 122 and the third air outlet zone 123, thereby facilitating the air conditioner 100 to achieve different air supply effects in multiple areas in the vertical direction.

[0115] By ensuring that the value of H4 satisfies 0.15*H≤H4≤0.45*H, more air blown from the air conditioner 100 can be brought closer to the front center of the air conditioner 100, enabling the air conditioner 100 to more effectively regulate the temperature in front of the air conditioner 100. It can also prevent the first air outlet zone 121 from having an excessively large vertical dimension, which would limit the size of the second air outlet zone 122 and the third air outlet zone 123. This makes it easier for the air conditioner 100 to achieve different air delivery effects in multiple areas in the vertical direction.

[0116] Reference Figure 1 , Figure 13 and Figure 14 According to some embodiments of the present invention, the height dimension of the housing component 10 in the vertical direction is H, the distance between the lower edge of the air outlet 12 and the bottom surface of the housing component 10 in the vertical direction is H1, the height dimension of the third air outlet area 123 in the vertical direction is H2, the height dimension of the second air outlet area 122 in the vertical direction is H3, and the height dimension of the first air outlet area 121 in the vertical direction is H4, where H = H1 + H2 + H3 + H4. This allows the upper side of the first air outlet area 121 to be located at the top of the housing in the vertical direction, resulting in a larger height dimension of the air outlet 12 in the vertical direction. This, in turn, increases the overall air outlet area of ​​the air conditioner 100, thereby enhancing the cooling / heating effect of the air conditioner 100.

[0117] The following reference Figures 1-14 An air conditioner 100 is described according to some embodiments of the present invention.

[0121] The height dimension of the housing component 10 in the vertical direction is H, the distance between the lower edge of the air outlet 12 and the bottom surface of the housing component 10 in the vertical direction is H1, the height dimension of the third air outlet zone 123 in the vertical direction is H2, the height dimension of the second air outlet zone 122 in the vertical direction is H3, and the height dimension of the first air outlet zone 121 in the vertical direction is H4. H = H1 + H2 + H3 + H4.

[0122] The range of H1 is 0.35m to 0.6m. The vertical height of the third air outlet zone 123 is H2, which satisfies 0.7m-H1≤H2≤1.0m-H1 or H2≤H1. The vertical height of the second air outlet zone 122 is H3, which satisfies 0.35*(H1+H2)≤H3≤0.7*(H1+H2). The vertical height of the first air outlet zone 121 is H4, which satisfies 0.15*H≤H4≤0.45*H.

[0123] The first grille section 41 includes a plurality of first grille ribs spaced apart in a horizontal direction, with a first flow channel 414 defined between adjacent first grille ribs, and the surface of the first grille rib facing the first flow channel 414 being a first flow surface 415.

[0124] The reference surface s passes through the longitudinal central axis of the housing component 10 and is perpendicular to the left and right direction. The longitudinal central axis of the housing component 10 extends in the up and down direction. When the setting surface extends inclined away from the reference surface s in the direction from back to front, the angle between the setting surface and the reference surface s is positive. When the setting surface extends inclined towards the reference surface s in the direction from back to front, the angle between the setting surface and the reference surface s is negative. The setting surface includes a first guide surface 415, a second guide surface 425, a third guide surface 4313, a fourth guide surface 4323, a first side wall surface 132, and a second side wall surface 133.

[0125] Wherein, at least a portion of the first guide surface 415 is formed as a planar or arcuate surface; and / or, at least a portion of the second guide surface 425 is formed as a planar or arcuate surface.

[0126] The first guide surface 415 forms an angle α with the reference surface s, the second guide surface 425 forms an angle β with the reference surface s, α is less than β, α is a positive value and its value ranges from 10° to 25°, and the difference between β and α ranges from 10° to 30°. The first sidewall surface 132 forms an angle γ with the reference surface s, both β and γ are positive, and γ+5°≤β≤γ+25°. The third guide surface 4313 forms an angle δ with the reference surface s, the fourth guide surface 4323 forms an angle θ with the reference surface s, δ is less than θ, δ is a positive value and its value ranges from 10° to 25°, and the difference between θ and δ ranges from 10° to 30°.

[0127] The angle between the second guide surface 425 on the second grille rib furthest from the first side wall 132 in the same second air outlet zone 122 and the reference plane s is the first included angle β1, and the angle between the second guide surface 425 on the other second grille ribs and the reference plane s is the second included angle β2. The first included angle β1 is smaller than the second included angle β2.

[0128] Multiple first grid ribs are divided into multiple groups of first grid ribs. Each group of first grid ribs includes at least one first grid rib. In the direction from the first side wall 132 to the second side wall 133, the multiple groups of first grid ribs are designated as first grid rib group one 411, first grid rib group two 412, and first grid rib group three 413. The width of the first grid rib in first grid rib group one 411 is P1, the width of the first grid rib in first grid rib group two 412 is P2, and the width of the first grid rib in first grid rib group three 413 is P3, where P1 < P2 ≤ P3. Specifically, 10mm ≤ P1 ≤ 15mm, 12mm ≤ P2 ≤ 30mm, and 15mm ≤ P3 ≤ 30mm.

[0129] Multiple second grid ribs are divided into multiple groups of second grid ribs. Each group of second grid ribs includes at least one second grid rib. In the direction from the first side wall 132 to the second side wall 133, the multiple groups of second grid ribs are second grid rib group one 421, second grid rib group two 422, and second grid rib group three 423. The width of the second grid rib in second grid rib group one 421 is Q1, the width of the second grid rib in second grid rib group two 422 is Q2, and the width of the second grid rib in second grid rib group three 423 is Q3, where Q1 = Q2 ≤ Q3.

[0130] When the air conditioner 100 is operating, the fan assembly 30 drives indoor air from the air inlet 11 into the casing component 10. After exchanging heat with the heat exchanger assembly 20, the air is blown out into the room through at least one of the two air outlets 12 to regulate the indoor temperature, for example, by lowering or raising the indoor temperature. As the airflow after heat exchange exits from the air outlet 12, it flows through the air guide grille 40, which can regulate the direction of the airflow passing through the air outlet 12.

[0131] The airflow blown out from the first air outlet 121 flows through the first guide channel 414 of the first grille section 41. During the flow through the first guide channel 414, the airflow is guided by the first guide surface 415 to adjust the air outlet direction of the first air outlet 121, so that the air blown out from the first air outlet 121 is directed towards the front center of the whole unit, so as to effectively regulate the temperature in front of the air conditioner 100.

[0132] The airflow from the second air outlet 122 flows through the second guide channel 424 of the second grille section 42. During the flow through the second guide channel 424, the airflow is guided by the second guide surface 425 to adjust the airflow direction of the second air outlet 122, so that the airflow from the second air outlet 122 is directed to the left and right sides, thereby reducing the discomfort caused by direct airflow to users located in front of the unit.

[0133] The airflow from the third air outlet zone 123 on the left flows through the left third guide channel 4312 of the left third grille 431. During the flow through the third guide channel, the airflow is guided by the third guide surface 4313 to adjust the air outlet direction of the third air outlet zone 123 on the left. This makes the air blown out of the third air outlet zone 123 on the left closer to the front center of the air conditioner 100, reducing or avoiding the airflow direction after heat exchange being too close to the left side of the air conditioner 100. This can reduce the impact of the air blown out of the third air outlet zone 123 on the accuracy of the inlet air temperature measured by the inlet air temperature sensor.

[0134] The airflow from the third air outlet zone 123 on the right side flows through the third guide channel 4322 of the third grille section 432 on the right side. During its flow through the third guide channel, it is guided by the fourth guide surface 4323 to adjust the airflow direction of the third air outlet zone 123 on the right side. This allows the airflow from the third air outlet zone 123 on the right side to be closer to the right side of the air conditioner 100, preventing the air from blowing directly onto the legs and improving the user experience.
