[0032] The air conditioner 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0033] According to the air conditioner 100 of the embodiment of the present utility model, Figure 1 and Figure 3 As shown, the air conditioner 100 includes: an air conditioner body 1 and an air outlet grille 2, the air conditioner body 1 includes a front panel 11 and air outlets 12 located on both sides of the front panel 11, the air outlet grille 2 is arranged at the air outlet 12, and the air outlet grille 2 includes longitudinal bars 21 extending along the length direction of the air outlet 12, the longitudinal bars 21 are multiple and spaced along the width direction of the air outlet 12, and an air flow channel 22 is defined between two adjacent longitudinal bars 21, and the longitudinal bars 21 include an upstream section 211 and a downstream section 212 arranged in sequence along the air outlet direction, and the downstream section 212 is deflected relative to the upstream section 211 toward the direction close to the front panel 11.

[0034] The air conditioner body 1 includes a front panel 11 located on the front side, and air outlets 12 are provided on both sides of the front panel 11. The air conditioner 100 supplies air through the air outlet 12 to adjust the temperature. The air outlet grille 2 is arranged at the air outlet 12. The air outlet grille 2 includes longitudinal bars 21 extending along the length direction of the air outlet 12 and transverse bars extending along the width direction of the air outlet inlet. The air outlet grille 2 blocks the air outlet 12 to prevent the user from putting his hand into the air conditioner body 1, preventing the user from touching the live components inside the air conditioner body 1, and protecting the user's safety.

[0035] There are multiple longitudinal bars 21 spaced apart, forming airflow channels 22 between the bars 21 for the airflow of the air conditioner 100. The longitudinal bars 21 of the present invention not only serve as a barrier for the user's safety, but also guide the airflow passing through, thereby improving the air supply effect of the air conditioner 100.

[0036] It is understandable that the air conditioner 100 includes a front panel 11 arranged on the front side, so the front panel 11 has a certain shielding effect on the air supply of the air conditioner 100 toward the front. In the related art, the air conditioner has the problem that no air can be blown in the front area.

[0037] The utility model improves the structure of the longitudinal grid bar 21. The longitudinal grid bar 21 includes an upstream section 211 and a downstream section 212 arranged in sequence along the air outlet direction. The airflow flowing out of the air outlet 12 passes through the upstream section 211 and the downstream section 212 in sequence. The downstream section 212 is deflected relative to the upstream section 211 in the direction close to the front panel 11. When the airflow passes through the longitudinal grid bar 21 and is sent out from the air outlet 12, it will be guided forward by the downstream section 212. Figure 1 As shown, the dotted line with an arrow is the direction of air flow, which can increase the forward air supply volume, improve the problem of insufficient air volume on the front side of the air conditioner 100, and enhance the air supply effect of the air conditioner 100.

[0038] According to the air conditioner 100 of the embodiment of the present invention, by designing the longitudinal grille 21 to be deflected in the direction of the downstream section 212 relative to the upstream section 211 close to the front panel 11, when the air flow passes through the longitudinal grille 21 and is sent out from the air outlet 12, it will be guided toward the front by the downstream section 212, thereby increasing the forward air supply volume, improving the problem of insufficient air volume on the front side of the air conditioner 100, and improving the air supply effect of the air conditioner 100.

[0039] In some embodiments of the present invention, the upstream section 211 extends along the outlet direction of the airflow, and the downstream section 212 is bent relative to the upstream section 211 toward the front panel 11. The upstream section 211 guides the airflow, reducing resistance at the air outlet 12 and improving airflow fluidity. After flowing along the upstream section 211, the airflow is then guided forward by the downstream section 212, thereby reducing airflow turbulence and improving airflow efficiency.

[0040] In some embodiments of the present invention, Figure 2 As shown, the angle θ1 between the side surface of the upstream section 211 close to the front panel 11 and the side surface of the downstream section 212 close to the front panel 11 is 90° to 165°.

[0041] It is worth noting that the thickness of the upstream section 211 may be non-uniform in the extension direction, or the thickness of the downstream section 212 may be non-uniform in the extension direction. Therefore, the embodiment of the present invention selects the angle between the side surface of the upstream section 211 close to the front panel 11 and the side surface of the downstream section 212 close to the front panel 11 that guides the airflow to describe the structural characteristics of the upstream section 211 and the downstream section 212.

[0042] If the angle θ1 between the side surface of the upstream section 211 near the front panel 11 and the side surface of the downstream section 212 near the front panel 11 is too large or too small, it is not conducive to the air outlet of the air conditioner 100. When the angle θ1 between the side surface of the upstream section 211 near the front panel 11 and the side surface of the downstream section 212 near the front panel 11 is too large, the extension directions of the upstream section 211 and the downstream section 212 tend to be consistent, and the guiding effect on the airflow is small, resulting in a small airflow in the direction of the front panel 11; when the angle θ1 between the side surface of the upstream section 211 near the front panel 11 and the side surface of the downstream section 212 near the front panel 11 is too small, the wind resistance of the airflow will increase, resulting in air volume loss.

[0043] In the embodiment of the present invention, the angle θ1 between the side surface of the upstream section 211 close to the front panel 11 and the side surface of the downstream section 212 close to the front panel 11 is set to 90°~165°, which can balance the airflow resistance and the forward wind guiding effect.

[0044] Optionally, the angle θ1 between the side surface of the upstream section 211 close to the front panel 11 and the side surface of the downstream section 212 close to the front panel 11 may be 90°, 100°, 120°, 150°, 165°, etc.

[0045] In other embodiments of the present invention, the thickness of the upstream section 211 is uniform, the thickness of the downstream section 212 is uniform, and the angle θ1 between the upstream section 211 and the downstream section 212 is 90° to 165°.

[0046] In some embodiments of the present invention, Figure 2 As shown, a side surface of the upstream section 211 close to the front panel 11 and a side surface of the downstream section 212 close to the front panel 11 are connected by a circular arc transition.

[0047] The side surface of the upstream section 211 close to the front panel 11 is used to guide the airflow, and the side surface of the downstream section 212 close to the front panel 11 is used to guide the airflow to the front. The side surface of the upstream section 211 close to the front panel 11 and the side surface of the downstream section 212 close to the front panel 11 are connected by a circular arc surface transition. The airflow transitions smoothly at the connection point, which can reduce the turbulence of the airflow, reduce the wind volume loss, and improve the air supply effect of the forward guide.

[0048] In some embodiments of the present invention, Figure 2 As shown, the thickness of the upstream section 211 gradually increases along the direction from the air inlet end of the upstream section 211 to the air outlet end of the upstream section 211; the thickness of the downstream section 212 gradually decreases along the direction from the air inlet end of the downstream section 212 to the air outlet end of the downstream section 212.

[0049] When air flows through the upstream section 211, it first passes through the air inlet end of the upstream section 211 and then flows through the air outlet end of the upstream section 211. The thickness of the upstream section 211 gradually increases from the air inlet end of the upstream section 211 to the air outlet end of the upstream section 211. The area of ​​the air flow channel 22 between the upstream sections 211 of two adjacent longitudinal bars 21 gradually decreases, thereby increasing the flow rate of the air from the air inlet end of the upstream section 211 to the air outlet end of the upstream section 211 and improving the air flow effect.

[0050] When air flows through the downstream section 212, it first passes through the air inlet end of the downstream section 212 and then flows through the air outlet end of the downstream section 212. The thickness of the downstream section 212 gradually decreases from the air inlet end of the downstream section 212 to the air outlet end of the downstream section 212. The area of ​​the air flow channel 22 between the downstream sections 212 of two adjacent longitudinal bars 21 gradually increases, which facilitates the smooth outflow of air from the air outlet grille 2.

[0051] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the air conditioner 100 is a cabinet unit, the length direction of the front panel 11 is the up-down direction, the length direction of the air outlet 12 is also the up-down direction, the two air outlets 12 are distributed on the left and right sides of the front panel 11, and the downstream section 212 is deflected toward the front side of the front panel 11 relative to the upstream section 211 to guide the airflow toward the front side of the front panel 11.

[0052] The air conditioner 100 is a cabinet unit, and two air outlets 12 are located on the left and right sides of the front panel 11. Therefore, two air outlet grilles 2 are provided, one corresponding to each of the air outlets 12. The front panel 11 provides some shielding for the air supply from the air conditioner 100 toward the front. The downstream section 212 is deflected relative to the upstream section 211 toward the front of the front panel 11, thereby increasing the forward airflow. This can improve the airflow problem of insufficient airflow at the front of the air conditioner 100 and enhance the air supply efficiency of the air conditioner 100.

[0053] In some embodiments of the present invention, Figure 2 As shown, the angle θ2 between the side surface of the downstream section 212 close to the front panel 11 and the normal of the front panel 11 is 0° to 45°.

[0054] The side surface of the downstream section 212 near the front panel 11 is used to deflect the airflow toward the front side. If the angle θ2 between the side surface of the downstream section 212 near the front panel 11 and the normal of the front panel 11 is too large or too small, it will be detrimental to the air output of the air conditioner 100. When the angle θ2 between the side surface of the downstream section 212 near the front panel 11 and the normal of the front panel 11 is too large, the airflow guiding effect of the downstream section 212 is reduced, and the effect of guiding the airflow toward the front side of the front panel 11 is weakened; when the angle θ2 between the side surface of the downstream section 212 near the front panel 11 and the normal of the front panel 11 is too small, it will increase wind resistance, cause air volume loss, and reduce the air volume output of the air conditioner 100.

[0055] In the embodiment of the present invention, the angle θ2 between the surface of the side of the downstream section 212 close to the front panel 11 and the normal of the front panel 11 is set to 0° to 45°, which can improve the air supply effect of the airflow flowing toward the front side of the front panel 11. It is worth noting that there are two air outlet grilles 2 and they are distributed on the left and right sides of the front panel 11. Figure 2 As shown, the downstream section 212 of the longitudinal grid bar 21 located on the left side of the front panel 11 is located on the left side of the normal direction of the front panel 11 to guide the airflow. Correspondingly, the downstream section 212 of the longitudinal grid bar 21 located on the right side of the front panel 11 is located on the right side of the normal direction of the front panel 11 to guide the airflow.

[0056] Optionally, the angle θ2 between the side surface of the downstream section 212 close to the front panel 11 and the normal of the front panel 11 may be 0°, 15°, 22.5°, 30°, 45°, etc.

[0057] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the air conditioner body 1 includes a fan component 13 located on the rear side of the front panel 11, and a duct component 14 located between the front panel 11 and the fan component 13. The duct component 14 defines two air outlet ducts 15. The fan component 13 includes a cross-flow impeller 131 whose axis extends in the up-down direction. The two air outlet ducts 15 extend from the outlet of the fan component 13 toward the air outlets 12 on the left and right sides respectively.

[0058] The cross-flow impeller 131 provides a flowing airflow, and the fan component 13 sends the airflow to the two air outlet ducts 15, and finally sends the airflow out from the air outlets 12 on the left and right sides, thereby increasing the air supply range of the air conditioner 100.

[0059] like Figure 1 and Figure 4 As shown, the air duct component 14 includes a front air duct wall 141 and a rear air duct wall 142 for defining the air outlet duct 15. The front air duct wall 141 and the rear air duct wall 142 extend in the up-down direction, and the front air duct wall 141 is arranged relative to the rear air duct wall 142 close to the front panel 11. Figure 2 As shown, the angle θ3 between the side surface of the upstream section 211 close to the front panel 11 and the rear air duct wall 142 is 0° to 45°.

[0060] There are two air outlet ducts 15, each of which includes a front air outlet wall 141 and a rear air outlet wall 142. The outlet of the air outlet duct 15 forms an air outlet 12, and the air outlet grille 2 is arranged at the air outlet 12. The angle θ3 between the side surface of the upstream section 211 close to the front panel 11 and the rear air outlet wall 142 refers to the angle between the upstream section 211 of the longitudinal grid bar 21 and the rear air outlet wall 142 of the air outlet duct 15 forming the air outlet 12 arranged corresponding to the longitudinal grid bar 21.

[0061] An outlet duct 15 for air flow is formed between the front duct wall 141 and the rear duct wall 142. The angle θ3 between the side surface of the upstream section 211 close to the front panel 11 and the rear duct wall 142 is 0°~45°. The extension direction of the upstream section 211 is slightly different from the flow direction of the air flow in the outlet duct 15, thereby reducing the turbulence of the air flow, reducing the wind resistance of the air flow, and improving the fluidity of the air flow of the upstream section 211. The upstream section 211 guides the air flow, which is then guided forward by the downstream section 212 in sequence, thereby improving the air outlet effect.

[0062] In some embodiments of the present invention, the front duct wall 141 and the rear duct wall 142 forming the outlet duct 15 are parallel to each other at least near the air outlet 12 , and an outlet section of equal width is formed between the front duct wall 141 and the rear duct wall 142 .

[0063] In some embodiments of the present invention, Figure 4 As shown, the air conditioner body 1 includes a duct component 14 located on the rear side of the front panel 11, and the duct component 14 defines two air outlet ducts 15. The two air outlet ducts 15 extend toward the air outlets 12 on the left and right sides respectively. The air conditioner body 1 also includes an air guide component 16. The air guide component 16 includes an air guide blade 161. The air guide blade 161 is an integrally formed part and includes two blade portions 1611. The two blade portions 1611 correspond to the two air outlet ducts 15 respectively.

[0064] The two air outlet ducts 15 supply air toward the air outlets 12 on the left and right sides, which can increase the air supply range of the air conditioner 100, and the blade portion 1611 arranged in the air outlet duct 15 can guide the air outlet of the air outlet duct 15, adjust the air outlet direction of the air conditioner 100, and further improve the air supply range of the air conditioner 100.

[0065] The air guide blade 161 is an integrally formed part and includes two blade portions 1611. Compared with the method of separately installing and matching multiple blades with the air conditioner body, by integrating the blade portions 1611 into a single part, the installation steps can be simplified and the assembly efficiency of the air guide component 16 can be improved.

[0066] like Figure 5 and Figure 6 As shown, the blade portion 1611 includes a flexible portion 1611a that can produce flexible deformation. The flexible portion 1611a includes a thin section 16111 and a thick section 16112 alternately arranged along the air outlet direction of the corresponding air outlet duct 15. The thickness of the flexible portion 1611a at the thick section 16112 is greater than the thickness at the thin section 16111.

[0067] Blade 1611 includes a flexible portion 1611a capable of recovering its deformation. Blade 1611 deforms in different directions and moves between different deformed shapes to direct airflow in different directions. The flexible portion 1611a of blade 1611 increases the deformation amplitude, broadening the range of motion of blade 1611 and improving airflow guidance. It also reduces damage caused by frequent deformation of blade 1611, thereby extending the service life of blade 1611.

[0068] The flexible portion 1611a includes a thin section 16111 and a thick section 16112. The thickness of the thick section 16112 is greater than the thickness of the thin section 16111. Therefore, the flexible portion 1611a is more likely to deform at the thin section 16111, which can increase the deformation amplitude of the blade portion 1611 and the movement range of the blade portion 1611, thereby enhancing the guiding effect of the airflow, so as to guide the airflow to a farther distance, thereby improving the air supply range of the air conditioner 100.

[0069] In some embodiments of the present invention, depressions are formed on both sides of the blade portion 1611 to form a thin section 16111 , which facilitates the deformation of the blade portion 1611 to swing upward or downward.

[0070] In some embodiments of the present invention, Figure 4As shown, the air duct component 14 includes a front air duct wall 141 and a rear air duct wall 142 for defining the air outlet duct 15. The front air duct wall 141 and the rear air duct wall 142 both extend in the up and down directions, and the front air duct wall 141 is arranged close to the front panel 11 relative to the rear air duct wall 142. The thick section 16112 is strip-shaped, and the two ends of the length of the thick section 16112 extend to both sides of the width of the blade portion 1611 respectively. The angle α between the length extension direction of the thick section 16112 and the corresponding front air duct wall 141 is 75°~105°.

[0071] There are two air outlet ducts 15, each air outlet duct 15 includes a front air duct wall 141 and a rear air duct wall 142. The outlet of the air outlet duct 15 forms an air outlet 12, and the air outlet grille 2 is arranged at the air outlet 12. The angle α between the length extension direction of the above-mentioned thick section 16112 and the corresponding front air duct wall 141 refers to the angle between the thick section 16112 of the blade portion 1611 and the front air duct wall 141 of the air outlet duct 15 arranged corresponding to the blade portion 1611.

[0072] A plurality of thick sections 16112 are provided on the blade portion 1611, and the plurality of thick sections 16112 are arranged at intervals along the air outlet direction of the air outlet duct 15. The angles α between the length extension directions of the plurality of thick sections 16112 and the corresponding front air duct wall 141 are all 75° to 105°. In this way, the deformation of the blade portion 1611 along the width direction of the air outlet duct 15 can be consistent, avoiding bending moments and certain angles being out of place.

[0073] In some embodiments of the present invention, multiple thick sections 16112 on the blade portion 1611 are arranged in parallel, allowing the blade portion 1611 to deform smoothly along the direction of airflow, thereby reducing airflow resistance and preventing interference between deformations of various parts of the blade portion 1611, thereby improving the operational reliability of the air guide blade 161. Furthermore, the parallel arrangement of multiple thick sections 16112 also reduces the manufacturing difficulty of the air guide blade 161, saving manufacturing costs.

[0074] In some embodiments of the present invention, the thickness of blade portion 1611 is equal at each thin section 16111. When blade portion 1611 is deformed by a driving force, the deformation of blade portion 1611 at each thin section 16111 is similar, allowing the entire blade portion 1611 to deform rapidly, improving response speed. Furthermore, the equal or similar thickness of blade portion 1611 at each thin section 16111 reduces the manufacturing difficulty of guide vane 161, saving manufacturing costs.

[0075] In some embodiments of the present invention, the thickness of the blade portion 1611 at the thin section 16111 ranges from 0.3 mm to 1.5 mm.

[0076] Optionally, the thickness of the blade portion 1611 at the thin section 16111 may be 0.3 mm, 0.35 mm, 0.5 mm, 0.55 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, etc.

[0077] In some embodiments of the present invention, Figure 5 As shown, the air guide blade 161 includes a mounting portion 1612 connected between two blade portions 1611. The air guide blade 161 is mounted to the air duct component 14 via the mounting portion 1612. The mounting portion 1612 is provided between the two blade portions 1611. The ends of the two blade portions 1611 away from the mounting portion 1612 are the air outlet ends of the blade portions 1611. The direction of airflow through the blade portions 1611 is the direction from the mounting portion 1612 to the air outlet ends of the blade portions 1611. The air outlet ends of the blade portions 1611 are close to the air outlet 12.

[0078] like Figure 6 and Figure 7 As shown, the blade portion 1611 has different thicknesses at at least two thin sections 16111 , and the thickness of the one relatively close to the mounting portion 1612 of the two thin sections 16111 with different thicknesses is not less than the thickness of the one relatively close to the air outlet 12 .

[0079] The thickness of the thin section 16111 of the blade portion 1611 near the air outlet 12 is less than or equal to the thickness of the thin section 16111 of the blade portion 1611 near the mounting portion 1612. Therefore, when the blade portion 1611 is driven to swing in the thickness direction to guide the air, the deformation of the part of the blade portion 1611 near the air outlet 12 is greater than the deformation of the part near the mounting portion 1612, so that the blade portion 1611 forms a smoothly transitioned curved surface, thereby improving the air guiding effect.

[0080] like Figure 8 As shown, the wind guide blade 161 swings downward, and the dotted line in the figure is a schematic line of the shape of the blade portion 1611 at the limit point of downward deformation, as shown in FIG. Figure 9 As shown, the wind guide blade 161 swings upward, and the dotted line in the figure is a schematic diagram of the shape of the blade portion 1611 at the extreme point of upward deformation. Compared with conventional rigid swing blades, the blade portion 1611 with the flexible portion 1611a in the embodiment of the utility model has lower flow resistance and higher flow efficiency. At the same wind guide angle, the windshield area of ​​the left and right blade portions 1611 is reduced by 24.0% and 26.6%, respectively. Moreover, compared with conventional rigid swing blades, the blade portion 1611 with the flexible portion 1611a in the embodiment of the utility model has a larger vertical wind guide angle. At the same driving force, the wind guide angle of the left and right blade portions 1611 is increased by 36.4% and 45.2%, respectively.

[0081] In some embodiments of the present invention, Figure 7As shown, the blade portion 1611 includes six thin sections 16111, A1-A6 are the thicknesses of the blade portion 1611 in the six thinning areas, and the thickness of the blade portion 1611 in multiple thin sections 16111 gradually increases from the air outlet 12 to the mounting portion 1612, A1<A2<A3<A4<A5<A6.
