[0002] In related technologies, air conditioners with two air outlets, one on the left and one on the right, experience less airflow directly in front of the unit during operation. Users positioned directly in front of the unit do not feel any breeze, resulting in poor temperature regulation in the area directly in front of the unit and uneven indoor temperature distribution. Therefore, improvements are needed. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this utility model is to provide an air conditioner whose air guide grille includes a first grille section and a second grille section, wherein the first grille section is located above the second grille section.

The surface of the first grille ribs facing the first guide channel is a first guide surface. The second grille section includes a plurality of second grille ribs spaced apart in a horizontal direction, and a second guide channel is defined between adjacent second grille ribs. The surface of the second grille ribs facing the second guide channel is a second guide surface. By making the angle α1 between the first guide surface and the reference plane smaller than the angle α2 between the second guide surface and the reference plane, the air blown from the first guide surface at the upper part of the air conditioner outlet can be closer to the front center of the air conditioner, which can more effectively regulate the temperature at the front of the unit. Furthermore, the air blown from the second guide surface at the lower part of the air conditioner outlet can be closer to the sides of the air conditioner, reducing or avoiding the discomfort caused by cold air blowing directly on the legs of the user located at the front of the unit. In addition, the combination of the first and second air guide surfaces allows the airflow at the air outlet to blow in different directions, which can enhance the uniformity of room temperature and improve user comfort.

[0030] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0031] Reference below Figure 1-Figure 5 This invention describes an air conditioner according to an embodiment of the present invention.

[0032] The air conditioner according to an embodiment of the present utility model, with reference to... Figure 1-Figure 5 It includes: housing component 10, heat exchanger assembly, fan assembly 21, and air guide grille 30. For example, the air conditioner is a split-type air conditioner, which includes an indoor unit 100 and an outdoor unit. For example, the air conditioner can be a split-type floor-standing air conditioner, in which case the indoor unit 100 can be a floor-standing indoor unit 100.

[0033] The housing component 10 has an air inlet 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 component 10, and the other air outlet 12 is located at the right end of the housing component 10. Each air outlet 12 extends vertically and includes a first air outlet area 13 and a second air outlet area 14, with the first air outlet area 13 located above the second air outlet area 14.

[0034] For example, the housing component 10 includes a partition strip 15 located at the air outlet 12. The partition strip 15 can extend horizontally. The air outlet area above the partition strip 15 is designated as the first air outlet area 13, and the air outlet area below the partition strip 15 is designated as the second air outlet area 14. By providing the partition strip 15 at the air outlet 12, the air outlet 12 can be conveniently divided into the first air outlet area 13 and the second air outlet area 14 arranged vertically. In addition, the partition strip 15 can also enhance the strength of the housing component 10, for example, by strengthening the structural strength near the air outlet 12 and reducing deformation.

[0035] The heat exchanger assembly and fan assembly 21 are housed within the casing 10, and the air guide grille 30 is also housed within the casing 10 and located at the air outlet 12. When the air conditioner is operating, the fan assembly 21 operates, driving indoor air into the casing 10 from the air inlet. After exchanging heat with the heat exchanger assembly, 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 it. As the airflow after heat exchange exits from the air outlet 12, it passes through the air guide grille 30, which thus regulates the direction of the airflow at the air outlet 12.

[0036] The air guide grille 30 includes a first grille section 31 and a second grille section 40. The first grille section 31 is located above the second grille section 40. The first grille section 31 corresponds to the first air outlet area 13, and the second grille section 40 corresponds to the second air outlet area 14. The airflow blowing out from the first air outlet area 13 is guided by the first grille section 31, and the airflow blowing out from the second air outlet area 14 is guided by the second grille section 40.

[0037] The first grille section 31 includes a plurality of first grille ribs 32 spaced apart in a horizontal direction. A first guide channel 33 is defined between adjacent first grille ribs 32, and the surface of the first grille ribs 32 facing the first guide channel 33 is a first guide surface 34. The airflow blown out from the first air outlet area 13 flows through the first guide channel 33 of the first grille section 31. During the flow through the first guide channel 33, the airflow is guided by the first guide surface 34 to adjust the airflow direction of the first air outlet area 13.

[0038] The second grille section 40 includes a plurality of second grille ribs 41 spaced apart in a horizontal direction. A second guide channel 42 is defined between adjacent second grille ribs 41, and the surface of the second grille ribs 41 facing the second guide channel 42 is a second guide surface 43. The airflow blown out from the second air outlet area 14 flows through the second guide channel 42 of the second grille section 40. During the flow through the second guide channel 42, the airflow is guided by the second guide surface 43 to adjust the airflow direction of the second air outlet area 14.

[0039] The angle between the first guide surface 34 and the reference surface is α1, and the angle between the second guide surface 43 and the reference surface is α2, where α1 is less than α2. The reference surface passes through the longitudinal central axis s 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 first guide surface 34 extends obliquely from back to front in a direction away from the reference surface, α1 is a positive value. When the first guide surface 34 extends obliquely from back to front in a direction closer to the reference surface, α1 is a negative value. When the second guide surface 43 extends obliquely from back to front in a direction away from the reference surface, α2 is a positive value. When the second guide surface 43 extends obliquely from back to front in a direction away from the reference surface, α2 is a negative value. By making the angle α1 between the first guide surface 34 and the reference surface smaller than the angle α2 between the second guide surface 43 and the reference surface, the air blown out by the first air outlet 13 at the top of the air conditioner can be closer to the front center of the air conditioner, which can more effectively regulate the temperature in front of the air conditioner, enhance the uniformity of the room temperature, and thus enhance the user experience. In addition, the air blown out by the second air outlet 14 at the bottom of the air conditioner can be closer to the sides of the air conditioner, preventing the air from blowing directly on the legs and enhancing the user experience.

[0040] Optionally, the air guide grille 30 can be a one-piece molded part, for example, the air guide grille 30 can be a one-piece injection molded part.

[0041] For example, the housing component 10 includes a partition strip 15 located at the air outlet 12. The air outlet area of ​​the air outlet 12 located above the partition strip 15 is the first air outlet area 13. The portion of the air guide grille 30 located above the partition strip 15 is the first grille portion 31. The air outlet area of ​​the air outlet 12 located below the partition strip 15 is the second air outlet area 14. The portion of the air guide grille 30 located below the partition strip 15 is the second grille portion 40. By providing the partition strip 15 at the air outlet 12, the air guide grille 30 can be easily divided into the first grille portion 31 and the second grille portion 40 arranged in the vertical direction.

[0042] For example, the divider 15 can extend horizontally and be thickened vertically, thereby reducing the significant difference in appearance between the first grille section 31 and the second grille section 40.

[0043] For example, the partition strip 15 also serves to support and connect for fixation. The first grid rib 32 is connected to the upper side of the partition strip 15, and the second grid rib 41 is connected to the lower side of the partition strip 15. By connecting both the first grid rib 32 and the second grid rib 41 to the partition strip 15, the air guide grille 30 can achieve higher structural strength and greater structural stability.

[0044] According to an embodiment of the present invention, the air conditioner's air guide grille 30 includes a first grille portion 31 and a second grille portion 40, wherein the first grille portion 31 is located above the second grille portion 40, the first grille portion 31 includes a plurality of first grille ribs 32 spaced apart in a horizontal direction, a first air guide channel 33 is defined between adjacent first grille ribs 32, and the surface of the first grille ribs 32 facing the first air guide channel 33 is a first air guide surface 34. The second grille portion 40 includes a plurality of second grille ribs 41 spaced apart in a horizontal direction, a second air guide channel 44 is defined between adjacent second grille ribs 41. 2. The surface of the second grille rib 41 facing the second airflow channel 42 is the second airflow guide surface 43. By making the angle α1 between the first airflow guide surface 34 and the reference plane smaller than the angle α2 between the second airflow guide surface 43 and the reference plane, the air blown from the first airflow guide surface 34 at the upper part of the air conditioner outlet 12 can be closer to the front center of the air conditioner, which can more effectively regulate the temperature directly in front of the unit. Furthermore, the air blown from the second airflow guide surface 43 at the lower part of the air conditioner outlet 12 can be closer to the sides of the air conditioner, reducing or avoiding discomfort caused by cold air blowing directly onto the legs of the user located directly in front of the unit. In addition, the cooperation of the first airflow guide surface 34 and the second airflow guide surface 43 allows the airflow from the outlet 12 to blow in different directions, which can enhance the uniformity of room temperature and improve user comfort.

[0045] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The difference between α2 and α1 is greater than 5°. For example, the difference between α2 and α1 can be 5°, 6°, 8°, 10°, 20°, etc. By making the difference between α2 and α1 greater than 5°, the direction of the air blown from the first air outlet zone 13 is significantly different from the direction of the air blown from the second air outlet zone 14, thereby making the temperature distribution in the room more uniform. It also makes the air blown from the first air outlet zone 13 more effective in regulating the temperature in front of the air conditioner, and reduces or avoids the discomfort caused by the air blown from the second air outlet zone 14 blowing directly on the legs of the user located directly in front of the unit.

[0046] According to some embodiments of this utility model, refer to Figure 4 and Figure 5The difference between α2 and α1 is less than 35°. For example, the difference between α2 and α1 can be 34°, 32°, 30°, 28°, etc. By making the difference between α2 and α1 less than 35°, the difference in air outlet direction between the first air outlet zone 13 and the second air outlet zone 14 can be avoided, thereby making the temperature distribution in the room more uniform.

[0047] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The difference between α2 and α1 ranges from 15° to 30°. By setting the difference between α2 and α1 within the range of 15° to 30°, it is possible to avoid excessive differences in the air outlet directions between the first air outlet zone 13 and the second air outlet zone 14, resulting in a more uniform temperature distribution in the room. It also allows the air blown from the first air outlet zone 13 to more effectively regulate the temperature in front of the air conditioner, and makes the air blown from the second air outlet zone closer to the sides of the air conditioner to prevent direct airflow onto the legs.

[0048] According to some embodiments of this utility model, α1 and α2 are both positive values, with α1 ranging from 2° to 18° and α2 ranging from 12° to 32°. For example, α1 can be 2°, 5°, 8°, 10°, 15°, 18°, etc. By setting α1 to a range of 2° to 18°, airflow can be avoided from concentrating directly in front of the unit, ensuring sufficient airflow in front of the unit. By setting α2 to a range of 12° to 32°, airflow can be avoided from concentrating on the left and right sides of the unit, reducing or preventing discomfort caused by airflow from the second air outlet 14 blowing directly onto the legs of the user located directly in front of the unit. This ensures sufficient airflow in front of the unit and on both sides, resulting in a more uniform airflow distribution around the unit, which is beneficial for uniform indoor temperature and reduces or prevents discomfort caused by cold air blowing directly onto the legs of the user located directly in front of the unit. According to some embodiments of this utility model, refer to... Figure 4 and Figure 5The housing component 10 has two air outlet channels 16 arranged in a left-right direction. The two air outlet channels 16 correspond to two air outlets 12, with the left air outlet channel 16 corresponding to the left air outlet 12 and the right air outlet channel 16 corresponding to the right air outlet 12. Each air outlet 12 is located at the outlet end of its corresponding air outlet channel 16. The airflow after heat exchange with the heat exchanger assembly within the housing component 10 flows to the two air outlet channels 16 and is blown out of the room from the two air outlets 12. The housing component 10 includes a front panel located between the two air outlets 12. The side wall of the air outlet channel 16 near the front panel is a first side wall 17, with an angle β between the first side wall 17 and a reference plane, where α1 < β - 15°. By making α1 < β - 15°, the first guide surface 34 can effectively guide air to the central part in front of the air conditioner, so that there is a large amount of air in front of the air conditioner, and users located in front of the air conditioner can have a noticeable breeze.

[0049] For example, the range of β mentioned above can be 45° to 75°, such as β can be 50°, 55°, 65°, 70°, etc.

[0050] According to some embodiments of this utility model, α1 < 40°. For example, the value of α1 can be 41°, 42°, 43°, 44°, 45°, etc. By making α1 < 40°, the air blown out by the first air outlet zone 13 can be closer to the front center of the air conditioner, which can more effectively regulate the temperature at the front of the entire unit.

[0051] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The housing component 10 has two air outlet channels 16 arranged in a left-right direction. The two air outlet channels 16 correspond to two air outlets 12, and each air outlet 12 is located at the air outlet end of the corresponding air outlet channel 16. The housing component 10 includes a front panel, which is located between the two air outlets 12. The side wall of the air outlet channel 16 near the front panel is a first side wall 17, and the angle between the first side wall 17 and the reference plane is β, where α2 < β - 15°. By making α2 < β - 15°, it is possible to avoid the air blown from the second air blowing area directly onto the user's legs, causing discomfort, and at the same time, to avoid the airflow below being too concentrated on both sides. This results in a larger airflow in the upper part of the space in front of the unit and a smaller airflow in the lower part. This allows the user to feel a noticeable breeze in the upper body while avoiding the discomfort caused by the larger airflow in the lower part blowing directly onto the legs.

[0052] According to some embodiments of this utility model, α2 < 40°. For example, the value of α2 can be 41°, 42°, 43°, 44°, 45°, etc. By making α2 < 40°, it is possible to avoid the air blown from the second air blowing zone directly onto the legs of the user located in front of the air conditioner, which would cause discomfort. At the same time, it is possible to avoid the airflow below being too concentrated on both sides, so that the upper air volume in the space in front of the whole unit is larger and the lower air volume is smaller. This way, the user can feel a clear breeze on the upper body, while avoiding the discomfort caused by the larger air volume in the lower layer blowing directly onto the legs.

[0053] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 In the air outlet direction of the air outlet 12, the width of the first grille rib 32 is greater than or equal to the width of the second grille rib 41. By making the width of the first grille rib 32 greater than or equal to the width of the second grille rib 41, the length of the first grille rib 32 can be made sufficiently long, thus giving the first grille rib 32 sufficient air guiding capacity and better air guiding effect. This results in better temperature regulation effect in the upper part of the air conditioner, allowing the user to feel a noticeable breeze on their upper body while avoiding the discomfort caused by a large airflow blowing directly on the legs from the lower part of the air conditioner.

[0054] According to some embodiments of this utility model, refer to Figure 2 The housing component 10 includes a front panel located between two air outlets 12. The first grille rib 32 closest to the front panel among a plurality of first grille ribs 32 is the first main grille rib 35, and the remaining first grille ribs 32 are first auxiliary grille ribs 36. In the air outlet direction of the air outlets 12, the width of the first main grille rib 35 is W3, and the width of the first auxiliary grille rib 36 is W4, where W3 > 15mm and 8mm < W4 < 20mm. For example, the value of W3 can be 16mm, 16.5mm, 17mm, 18mm, etc.; the value of W4 can be 8.5mm, 9mm, 10mm, 12mm, 14mm, 16mm, 18mm, 19mm, etc. Because the first main grille rib 35 is closer to the front panel of the air conditioner, its airflow guiding effect is greater. By making the width (W3) of the first main grille rib 35 greater than 15mm, it can more effectively guide the airflow and change its direction. Similarly, by making the width (W4) of the first auxiliary grille rib 36 greater than 8mm, it can also effectively guide the airflow and change its direction. If the length of the first auxiliary grille rib 36 exceeds 20mm, it will reduce the airflow from the air conditioner by more than 40m³. 3 / h, by making the length of the first auxiliary grille rib 36 less than 20mm, the impact of the first auxiliary grille rib 36 on airflow loss can be reduced.

[0055] According to some embodiments of this utility model, refer to Figure 3 The housing component 10 includes a front panel located between two air outlets 12. Among the plurality of second grille ribs 41, the second grille rib 41 closest to the front panel is the second main grille rib 44, and the remaining second grille ribs 41 are second auxiliary grille ribs 45. In the air outlet direction of the air outlets 12, the width of the second main grille rib 44 is W5, and the width of the second auxiliary grille rib 45 is W6, where W5 > 15mm and 8mm < W6 < 20mm. For example, the value of W5 can be 16mm, 16.5mm, 17mm, 18mm, etc.; the value of W6 can be 8.5mm, 9mm, 10mm, 12mm, 14mm, 16mm, 18mm, 19mm, etc. Because the second main grille rib 44 is closer to the front panel of the air conditioner, its airflow guiding effect is greater. By making the width (W5) of the second main grille rib 44 greater than 15mm, it can more effectively guide the airflow and change and guide its direction. Similarly, by making the width (W6) of the second auxiliary grille rib 45 greater than 8mm, it can also effectively guide the airflow and change its direction. However, if the length of the second auxiliary grille rib 45 exceeds 20mm, it will reduce the airflow volume from the air conditioner by more than 40m³. 3 / h, by making the length of the second auxiliary grille rib 45 less than 20mm, the impact of the second auxiliary grille rib 45 on the loss of air volume can be reduced.

[0056] According to some embodiments of this utility model, refer to Figure 2 At least a portion of the first guide surface 34 is formed as a plane. By making at least a portion of the first guide surface 34 a plane, the structure of the first guide surface 34 is simple and easy to process and shape.

[0057] According to some embodiments of this utility model, refer to Figure 3 At least a portion of the second guide surface 43 is formed as an arc-shaped surface. By forming at least a portion of the second guide surface 43 as an arc-shaped surface, the second guide surface 43 can have a better guiding effect while reducing the impact of the second guide surface 43 on the outlet air volume.

[0058] According to some embodiments of this utility model, refer to Figure 1The first air outlet zone 13 has a vertical length of L1, and the second air outlet zone 14 has a vertical length of L2. The ratio of L1 / L2 ranges from 0.8 to 1.2. By setting the range of L1 / L2 to 0.8 to 1.2, for example, L1 / L2 can take values ​​of 0.8, 0.9, 1.0, 1.1, 1.2, etc., the airflow from the air outlet 12 facing directly in front of the air conditioner is less different from the airflow from the air outlet 12 facing the left and right sides of the air conditioner. This results in more uniform airflow around the entire unit, which helps improve the uniformity of indoor temperature.

[0059] According to some embodiments of this utility model, refer to Figure 1 The length of the first air outlet zone 13 in the vertical direction is L1, and the total length of the air outlet 12 in the vertical direction is L3, where L1 / L3 ≥ 1 / 3. For example, the value of L1 / L3 can be 1 / 3, 1 / 2, 2 / 3, 3 / 4, etc. By ensuring that the ratio of the length L1 of the first air outlet zone 13 in the vertical direction to the total length L3 of the air outlet 12 in the vertical direction is not less than 1 / 3, the area of ​​the first air outlet zone 13 can be made large enough, allowing more air blown from the air conditioner to be closer to the front center of the air conditioner, enabling the air conditioner to more effectively regulate the temperature in front of the air conditioner.
