[0055] Embodiments of the present invention are described in detail below, examples of which 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0056] The following describes an air outlet frame assembly 40 according to an embodiment of the present invention with reference to the accompanying drawings.

[0057] Reference Figure 2-Figure 3 and Figure 9-10The air outlet frame assembly 40 according to the first embodiment of the present invention includes: an air outlet frame 5 and a protective net 6, the air outlet frame 5 includes a first frame body 51 and a second frame body 52, the first frame body 51 and the second frame body 52 are independently formed, and the first frame body 51 and the second frame body 52 jointly define an air outlet channel 50; the protective net 6 is arranged in the air outlet channel 50, and the first frame body 51 and the second frame body 52 jointly limit the protective net 6 to install the protective net 6 on the air outlet frame 5.

[0058] The first frame body 51 and the second frame body 52 are formed independently, and the first frame body 51 and the second frame body 52 can be separately processed and then assembled into the air outlet frame 5, which can reduce the difficulty of processing the air outlet frame 5.

[0059] By providing a protective net 6 in the air outlet passage 50, it is possible to prevent a human hand from reaching into the interior of the whole machine through the air outlet passage 50 and touching the internal rotating wind wheel 32, thereby improving safety. The above-mentioned air outlet frame assembly 40 can be used in an air conditioner, for example, the air outlet frame assembly 40 can be used in an air conditioner indoor unit 100 of an air conditioner, and the protective net 6 is provided in the air outlet passage 50, which can prevent a human hand from reaching into the air conditioner indoor unit 100 through the air outlet passage 50 and touching the wind wheel 32 and other components, thereby improving safety.

[0060] The first frame body 51 and the second frame body 52 jointly limit the protective net 6 so as to install the protective net 6 on the air outlet frame 5 . The protective net 6 can be sandwiched between the first frame body 51 and the second frame body 52 .

[0061] Since the first frame 51 and the second frame 52 are formed independently, the protective net 6 can be installed when the first frame 51 and the second frame 52 are assembled, so that the protective net 6 can be clamped between the first frame 51 and the second frame 52, and there is no need to insert hands or operating tools into the air outlet channel 50 of the air outlet frame 5 to install the protective net 6, thereby avoiding such inconvenient operation; thus, the protective net 6 is installed by limiting the position of the protective net 6 by the first frame 51 and the second frame 52, which makes the installation operation of the protective net 6 more convenient.

[0062] Reference Figure 4 According to some embodiments of the present invention, the first frame 51 and the second frame 52 are arranged along the second direction, the first frame 51 is located on the side of the second frame 52 adjacent to the air outlet 110, and the second direction intersects with the thickness direction of the protective net 6. Through the arrangement of the first frame 51 and the second frame 52, the structure of the air outlet frame assembly 40 is more compact, and the space occupied by the air outlet frame assembly 40 can be reduced.

[0063] For example, refer to Fig. 9 and Fig.10The second direction can refer to the left-right direction in the drawings, and the thickness direction of the protective net 6 can refer to the front-back direction in the drawings. The second direction is perpendicular to the thickness direction of the protective net 6. When the first frame 51 and the second frame 52 are arranged along the second direction, the first frame 51 and the second frame 52 jointly define the air outlet channel 50, and a portion of the first frame 51 forms a right side wall 510 of the air outlet channel 50, and a portion of the second frame 52 forms a left side wall 520 of the air outlet channel 50.

[0064] According to the air outlet frame assembly 40 of the first aspect of the embodiment of the present invention, a protective net 6 is arranged in the air outlet channel 50 to prevent human hands from reaching into the interior of the whole machine through the air outlet channel 50 and touching the wind wheel 32 rotating inside the whole machine, thereby improving safety; the first frame body 51 and the second frame body 52 are formed independently, and the protective net 6 can be installed when the first frame body 51 and the second frame body 52 are assembled, so that the protective net 6 can be clamped between the first frame body 51 and the second frame body 52. ​​The protective net 6 is installed in such a way that the first frame body 51 and the second frame body 52 limit the protective net 6, which makes the installation operation of the protective net 6 more convenient.

[0065] Reference Figure 6-Figure 8 According to some embodiments of the present invention, the protective net 6 has a first end 61 and a second end 62, and the first end 61 and the second end 62 are arranged opposite to each other along a first direction, and the first direction intersects with the thickness direction of the protective net 6. The first frame 51 is formed with a first limiting slot 511, and the second frame 52 and the first frame 51 jointly define a second limiting slot 521, and the first end 61 is inserted into the first limiting slot 511, and the second end 62 is inserted into the second limiting slot 521. The first limiting slot 511 can limit the first end 61 of the protective net 6, and the second limiting slot 521 can limit the second end 62 of the protective net 6, so that both ends of the protective net 6 along the first direction are limited, thereby realizing the installation of the protective net 6 on the air outlet frame 5, and the installation structure is simple, the operation is convenient, and the installation efficiency can be improved.

[0066] For example, refer to Figure 6-Figure 8 , the first direction can refer to the up-down direction in the accompanying drawings, and the first direction is perpendicular to the thickness direction of the protective net 6. The first limiting slot 511 is formed at the upper part of the first frame 51, and the lower part of the first frame 51 and the lower part of the second frame 52 jointly define the second limiting slot 521; the first end 61 is the upper end of the protective net 6, and the second end 62 is the lower end of the protective net 6. The first end 61 can be inserted into the first limiting slot 511 upwards, and the second end 62 can be inserted into the second limiting slot 521 downwards.

[0067] Reference Figure 7According to some optional embodiments of the present invention, the groove depth D of the first limiting slot 511 is 5 to 10 mm. For example, the groove depth D of the first limiting slot 511 may be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm.

[0068] It can be understood that there is airflow passing through the air outlet channel, and the airflow in the air outlet channel can have different temperatures. When the temperature in the air outlet channel changes, the air outlet frame will be deformed due to thermal expansion and contraction, and the groove wall of the first limiting slot will also be deformed. In this way, the first end of the protective net is easy to contact and rub against the groove wall of the first limiting slot, producing abnormal noise.

[0069] By ensuring that the groove depth D of the first limiting slot 511 is not less than 5 mm, the first end 61 of the protective net 6 can have sufficient mobility in the first limiting slot 511, thereby preventing the air outlet frame 5 from expanding and contracting due to temperature changes in the air outlet channel 50 and causing abnormal noise from contact and friction with the protective net 6; by ensuring that the groove depth D of the first limiting slot 511 is not greater than 10 mm, it can prevent the first limiting slot 511 from occupying too much space, thereby making the overall structure of the air outlet frame 5 compact.

[0070] Therefore, by making the groove depth D of the first limiting slot 511 5 to 10 mm, the compactness of the overall structure of the air outlet frame 5 can be ensured, and the first end 61 of the protective net 6 can have a certain amount of movement in the first limiting slot 511, thereby preventing the air outlet frame 5 from deforming due to thermal expansion and contraction and causing contact and friction with the protective net 6 to produce abnormal noise.

[0071] Reference Figure 7 According to some optional embodiments of the present invention, the end face of the first end 61 of the protective net 6 is the first end face 611, and the distance D1 between the first end face 611 and the bottom of the first limiting slot 511 is in the range of 2 to 5 mm. For example, the distance D1 between the first end face 611 and the bottom of the first limiting slot 511 may be 2 mm, 3 mm, 4 mm or 5 mm.

[0072] By ensuring that the spacing D1 between the first end face 611 and the bottom of the first limiting slot 511 is not less than 2 mm, the first end 61 can have sufficient mobility in the first limiting slot 511, thereby preventing the air outlet frame 5 from expanding and contracting due to temperature changes in the air outlet channel 50, causing the bottom of the slot to contact and rub against the first end face 611 and produce abnormal noise; by ensuring that the spacing D1 between the first end face 611 and the bottom of the first limiting slot 511 is not greater than 5 mm, the spacing between the first end face 611 and the bottom of the slot of the first limiting slot 511 is prevented from being too large, thereby making the overall structure of the air outlet frame assembly 40 more compact.

[0073] Therefore, there is a suitable spacing range between the first end face 611 and the bottom of the first limiting slot 511, which can not only ensure the compactness of the overall structure of the air outlet frame 5, but also allow the first end 61 of the protective net 6 to have a certain amount of activity in the first limiting slot 511, thereby preventing the air outlet frame 5 from deforming due to thermal expansion and contraction and causing contact and friction with the protective net 6 to produce abnormal noise.

[0074] Reference Figure 6-Figure 12 According to some optional embodiments of the present invention, the protective net 6 includes a net body 63, the net body 63 includes a plurality of mesh strips 64, the plurality of mesh strips 64 are arranged at intervals along the second direction, and the mesh strips 64 extend along the first direction. The second frame 52 is provided with a first limiting structure 522, the first limiting structure 522 is located between adjacent mesh strips 64 to limit the protective net 6 in the second direction, the second direction, the first direction and the thickness direction of the protective net 6 intersect each other, for example, the second direction can refer to the left and right direction in the accompanying drawings, and the second direction, the first direction and the thickness direction of the protective net 6 are perpendicular to each other.

[0075] By locating the first limiting structure 522 between adjacent mesh strips 64 , the first limiting structure 522 can limit the position of the protective net 6 in the second direction, thereby reducing the possibility of the protective net 6 moving in the second direction, thereby further improving the stability and reliability of the protective net 6 .

[0076] Reference Figure 6-Figure 11 In some optional embodiments of the present invention, the first limiting structure 522 includes a first limiting protrusion 523 and a second limiting protrusion 524, and the first limiting protrusion 523 and the second limiting protrusion 524 are respectively located at the two ends of the second frame 52 along the first direction. For example, the first limiting protrusion 523 is located at the upper end of the second frame 52, and the second limiting protrusion 524 is located at the lower end of the second frame 52. The first limiting protrusion 523 and the second limiting protrusion 524 are both located between adjacent mesh strips 64, and can both limit the protective net 6 in the second direction.

[0077] The first limiting protrusion 523 is adjacent to the first limiting slot 511, and the second limiting protrusion 524 is adjacent to the second limiting slot 521. The first limiting protrusion 523 can limit the first end 61 of the protective net 6 in the second direction, and the second limiting protrusion 524 can limit the second end 62 of the protective net 6 in the second direction, thereby achieving the upper limit positioning of the protective net 6 in the second direction, so as to further improve the stability of the installation of the protective net 6 on the air outlet frame 5 and improve the reliability of the protective net 6.

[0078] For example, when assembling the protective net 6, the first end 61 of the protective net 6 can be inserted into the second limiting slot 521, and the second end 62 of the protective net 6 can be inserted into the first limiting slot 511, so that the protective net 6 cooperates with the first frame 51; then the second frame 52 is assembled with the first frame 51, so that the first limiting protrusion 523 and the second limiting protrusion 524 are both located between adjacent mesh strips 64, so as to limit the protective net 6 in the second direction.

[0079] Reference Fig.10 and Fig.11 In some optional embodiments of the present invention, the first limiting protrusions 523 may be two arranged at intervals along the second direction, and the two first limiting protrusions 523 are adjacent to the opposite ends of the protective net 6 along the second direction. The first limiting protrusions 523 can limit the protective net 6 at the opposite ends of the protective net 6 along the second direction to further ensure the installation stability of the protective net 6.

[0080] In some optional embodiments of the present invention, the second limiting protrusions 524 may be two arranged at intervals along the second direction, and the two second limiting protrusions 524 are adjacent to the opposite ends of the protective net 6 along the second direction. The second limiting protrusions 524 can limit the protective net 6 at the opposite ends of the protective net 6 along the second direction to further ensure the installation stability of the protective net 6.

[0081] In some optional embodiments of the present invention, there are two first limiting protrusions 523 arranged at intervals along the second direction, and the two first limiting protrusions 523 are adjacent to the opposite ends of the protective net 6 along the second direction; and, there are two second limiting protrusions 524 arranged at intervals along the second direction, and the two second limiting protrusions 524 are adjacent to the opposite ends of the protective net 6 along the second direction.

[0082] Therefore, the first limiting protrusion 523 can limit the protective net 6 at the opposite ends of the protective net 6 along the second direction, and the second limiting protrusion 524 can limit the protective net 6 at the opposite ends of the protective net 6 along the second direction, so that the installation of the protective net 6 on the air outlet frame 5 is more stable and reliable.

[0083] Reference Figure 7-Figure 8 and Figure 12-13 In some optional embodiments of the present invention, the protective net 6 includes a net convex strip 65, which is protruded on at least one side of the net body 63 in the thickness direction and extends along the second direction. The net convex strip 65 located at the first end 61 is a first net convex strip 651, and the net convex strip 65 located at the second end 62 is a second net convex strip 652.

[0084] The mesh convex strips 65 are convexly arranged on at least one side in the thickness direction of the mesh main body 63, which may include the following situations: the mesh convex strips 65 are convexly arranged on one side in the thickness direction of the mesh main body 63; or, the mesh convex strips 65 are convexly arranged on two opposite sides in the thickness direction of the mesh main body 63. For example, according to a specific embodiment of the present invention, the mesh convex strips 65 are all located on the rear side of the mesh main body 63.

[0085] Among them, refer to Figure 7-Figure 8 The first mesh convex strip 651 is located in the first limiting slot 511, and the first mesh convex strip 651 is located on the side of the first limiting protrusion 523 adjacent to the bottom of the first limiting slot 511, the first mesh convex strip 651 and the first limiting protrusion 523 are arranged opposite to each other in the first direction, and the first limiting protrusion 523 can limit the first mesh convex strip 651 in the first direction to prevent the first end 61 from escaping from the first limiting slot 511 in the direction away from the bottom of the slot, thereby preventing the protective net 6 from escaping from the air outlet frame 5 and ensuring the stability of the protective net 6.

[0086] The second mesh convex strip 652 is located in the second limiting slot 521, and the second mesh convex strip 652 is located on the side of the second limiting protrusion 524 adjacent to the bottom of the second limiting slot 521, the second mesh convex strip 652 and the second limiting protrusion 524 are arranged opposite to each other in the first direction, and the second limiting protrusion 524 can limit the second mesh convex strip 652 in the first direction to prevent the second end 62 from escaping from the second limiting slot 521 in the direction away from the bottom of the slot, thereby preventing the protective net 6 from escaping from the air outlet frame 5 and ensuring the stability of the protective net 6.

[0087] For example, the first direction can be the up and down direction, the first limiting protrusion 523 can be located on the lower side of the first mesh protrusion 651, and the first limiting protrusion 523 can limit the first mesh protrusion 651 in the downward direction, limit the downward movement of the protective net 6, and prevent the protective net 6 from escaping from the first limiting slot 511; the second limiting protrusion 524 can be located on the upper side of the second mesh protrusion 652, and the second limiting protrusion 524 can limit the second mesh protrusion 652 in the upward direction, limit the upward movement of the protective net 6, and prevent the protective net 6 from escaping from the second limiting slot 521.

[0088] Therefore, through the matching relationship between the first limiting protrusion 523 and the first net protrusion 651, and through the matching relationship between the second limiting protrusion 524 and the second net protrusion 652, the first limiting structure 522 can limit the protective net 6 in the first direction to prevent the protective net 6 from escaping from the first limiting slot 511 or the second limiting slot 521, thereby further enhancing the stability of the installation of the protective net 6.

[0089] Reference Figure 7In some optional embodiments of the present invention, the distance D2 between the first mesh protrusion 651 and the first limiting protrusion 523 in the first direction is 2 to 5 mm, for example, the distance D2 may be 2 mm, 3 mm, 4 mm or 5 mm.

[0090] It is understandable that the airflow in the air outlet channel can have different temperatures. When the temperature in the air outlet channel changes, the air outlet frame will be deformed due to thermal expansion and contraction, the second frame will be deformed, and the first limiting protrusion and the second limiting protrusion may also be deformed. In this way, the distance between the first limiting protrusion and the first mesh protrusion may be reduced, and the distance between the second limiting protrusion and the second mesh protrusion may also be reduced. The first limiting protrusion is easy to contact and rub with the first mesh protrusion and produce abnormal noise, and the second limiting protrusion is easy to contact and rub with the second mesh protrusion and produce abnormal noise.

[0091] By ensuring that the spacing D2 between the first mesh ridge 651 and the first limiting protrusion 523 in the first direction is not less than 2 mm, the first mesh ridge 651 can have sufficient mobility, ensuring that there is a sufficient spacing between the first mesh ridge 651 and the first limiting protrusion 523, thereby preventing the first frame body 51 from contacting and rubbing with the first mesh ridge 651 to produce abnormal noise due to thermal expansion and contraction deformation caused by temperature changes in the air outlet channel 50; by ensuring that the spacing D2 between the first mesh ridge 651 and the first limiting protrusion 523 in the first direction is not greater than 5 mm, it can be avoided that the spacing between the first mesh ridge 651 and the first limiting protrusion 523 is too large, thereby making the structure of the air outlet frame assembly 40 compact.

[0092] Therefore, the distance D2 between the first mesh protrusion 651 and the first limiting protrusion 523 in the first direction is 2 to 5 mm, which can not only ensure the compactness of the overall structure of the air outlet frame assembly 40, but also ensure that there is a sufficient distance between the first mesh protrusion 651 and the first limiting protrusion 523, so as to avoid the second frame body 52 from deforming due to thermal expansion and contraction and contacting and rubbing with the first mesh protrusion 651 to produce abnormal noise.

[0093] Reference Figure 8 In some optional embodiments of the present invention, the distance D3 between the second mesh protrusion 652 and the second limiting protrusion 524 in the first direction is 3 to 8 mm, for example, the distance D3 may be 3 mm, 4 mm, 5 mm, 6 mm, 7 mm or 8 mm.

[0094] By ensuring that the spacing D2 between the second mesh ridge 652 and the second limiting protrusion 524 in the first direction is not less than 3 mm, the second mesh ridge 652 can have sufficient mobility, ensuring that there is a sufficient spacing between the second mesh ridge 652 and the second limiting protrusion 524, thereby preventing the second frame 52 from expanding and contracting due to temperature changes in the air outlet channel 50 and causing contact and friction with the second mesh ridge 652 to produce abnormal noise; by ensuring that the spacing D2 between the second mesh ridge 652 and the second limiting protrusion 524 in the first direction is not greater than 8 mm, it can prevent the spacing between the first mesh ridge 651 and the first limiting protrusion 523 from being too large, thereby making the structure of the air outlet frame assembly 40 compact.

[0095] Therefore, the distance D2 between the second mesh ridge 652 and the second limiting protrusion 524 in the first direction is 3 to 8 mm, which can not only ensure the compactness of the overall structure of the air outlet frame assembly 40, but also ensure that there is a sufficient distance between the second mesh ridge 652 and the second limiting protrusion 524, so as to avoid the second frame body 52 from deforming due to thermal expansion and contraction and contacting and rubbing with the second mesh ridge 652 to produce abnormal noise.

[0096] Reference Figure 7 and Figure 8 In some optional embodiments of the present invention, the distance D3 between the second mesh protrusion 652 and the second limiting protrusion 524 in the first direction is 3 to 8 mm, and the distance D2 between the first mesh protrusion 651 and the first limiting protrusion 523 in the first direction is 2 to 5 mm.

[0097] Therefore, the spacing D2 between the first mesh ridge 651 and the first limiting protrusion 523 in the first direction is 2 to 5 mm, and the spacing D2 between the second mesh ridge 652 and the second limiting protrusion 524 in the first direction is 3 to 8 mm, which can not only ensure the compactness of the overall structure of the air outlet frame assembly 40, but also ensure that there is sufficient spacing between the first mesh ridge 651 and the first limiting protrusion 523, and ensure that there is sufficient spacing between the second mesh ridge 652 and the second limiting protrusion 524, so as to avoid the second frame body 52 from contacting and rubbing with the first mesh ridge 651 due to thermal expansion and contraction deformation and producing abnormal noise, and avoid the second frame body 52 from contacting and rubbing with the second mesh ridge 652 due to thermal expansion and contraction deformation and producing abnormal noise.

[0098] Reference Fig.12 and Fig.13In some optional embodiments of the present invention, the two ends of the second mesh convex strip 652 along the second direction are respectively a first extension end 653 and a second extension end 654. In the second direction, the length of the first extension end 653 protruding from the mesh body 63 is L1, and the length of the second extension end 654 protruding from the mesh body 63 is L2. L1 is greater than L2, and the ratio of L1 to L2 ranges from 2 to 4. For example, the ratio of L1 to L2 can be 2, 3 or 4. When the ratio of L1 to L2 is 3, L1 can be 9 mm and L2 can be 3 mm.

[0099] The length L1 of the first extension end 653 protruding from the net body 63 and the length L2 of the second extension end 654 protruding from the net body 63 are quite different. This can clearly distinguish the assembly direction of the protective net 6 in the second direction, prevent the protective net 6 from being installed incorrectly on the air outlet frame 5, and ensure the limiting effect of the second limiting protrusion 524 on the second net protrusion 652, and ensure the limiting effect of the first limiting protrusion 523 on the first net protrusion 651, thereby ensuring the limiting effect of the first limiting structure 522 on the protective net 6 in the first direction.

[0100] Reference Fig.17 According to some optional embodiments of the present invention, in the second direction, the second end 62 is spaced apart from the side walls of the second limiting slot 521 on opposite sides along the second direction, and the second direction, the first direction and the thickness direction of the protective net 6 intersect each other.

[0101] When the temperature in the air outlet channel changes, the first frame body will be deformed, and the groove wall of the first limiting slot may also be deformed, so that the second end is easy to contact and rub with the first mesh convex strip and produce abnormal sound.

[0102] The second end 62 is spaced apart from the side walls of the second limiting slot 521 on both sides opposite to each other along the second direction to ensure that there is a sufficient distance between the second end 62 and the side walls of the second limiting slot 521. This can prevent the first frame 51 from expanding and contracting due to temperature changes in the air outlet channel 50 and causing contact and friction with the second end 62 to produce abnormal noise, and facilitate the assembly of the protective net 6.

[0103] Reference Fig.17 In some optional embodiments of the present invention, in the second direction, a distance L3 between two opposite sides of the second end 62 along the second direction and the side wall of the second limiting slot 521 is 1 to 3 mm.

[0104] For example, the second web convex strip 652 is located in the second limiting slot 521, and the spacing between the two opposite sides of the second end 62 along the second direction and the side wall of the second limiting slot 521 can be considered as the spacing between the two ends of the second web convex strip 652 along the second direction and the side wall of the second limiting slot 521, which is respectively the spacing between the first extension end 653 and the second extension end 654 and the side wall of the second limiting slot 521. The first extension end 653 is adjacent to the side wall of one side of the second limiting slot 521 along the second direction, and the spacing L3 between the two is 1 to 3 mm, and the first extension end 653 is adjacent to the side wall of the other side of the second limiting slot 521 along the second direction, and the spacing L3 between the two is 1 to 3 mm. Among them, the spacing L3 can be 1 mm, 2 mm or 3 mm.

[0105] By ensuring that the spacing L3 between the second end 62 and the side walls of the second limiting slot 521 along the second direction is not less than 1 mm, there is a sufficient spacing between the second end 62 and the side walls of the second limiting slot 521 to prevent the first frame body 51 from expanding and contracting due to temperature changes in the air outlet channel 50 and causing contact and friction with the second end 62 to produce abnormal noise; by ensuring that the spacing L3 between the second end 62 and the side walls of the second limiting slot 521 along the second direction is not greater than 3 mm, it is possible to prevent the second section from having an excessively large spacing with the side walls of the second limiting slot 521, thereby making the structure of the air outlet frame assembly 40 compact.

[0106] Reference Figure 12-Figure 17 According to some optional embodiments of the present invention, the protective net 6 includes a net body 63, the net body 63 includes a plurality of net strips 64, the plurality of net strips 64 are arranged at intervals along the second direction, and the net strips 64 extend along the first direction. The first direction is the up-down direction, the second end 62 of the protective net 6 is the lower end of the protective net 6, the bottom of the second limiting slot 521 is provided with a support structure 53, the lower end of the protective net 6 is supported by the support structure 53, and the second direction, the first direction and the thickness direction of the protective net 6 intersect each other.

[0107] The lower end of the protective net 6 is supported on the support structure 53, and the support structure 53 can limit the protective net 6 in the downward direction, preventing the protective net 6 from moving downward under the action of external force or its own gravity, and preventing the second end 62 of the protective net 6 from escaping from the second limiting slot 521, so as to improve the installation stability of the protective net 6. In addition, the lower end of the protective net 6 is supported on the support structure 53, so that the contact area between the lower end of the protective net 6 and the air outlet frame 5 is small, which is conducive to reducing the friction between the lower end of the protective net 6 and the air outlet frame 5, and can reduce abnormal noise.

[0108] Reference Fig.17In some optional embodiments of the present invention, the supporting structure 53 is a supporting protrusion 531, and the supporting protrusion 531 is located in the middle of the protective net 6 along the second direction. The supporting protrusion 531 can support the protective net 6 in the middle of the protective net 6 along the second direction, and limit the protective net 6. It can enhance the uniformity of the force at both ends of the protective net 6 along the second direction, thereby improving the stability of the protective net 6.

[0109] Reference Figure 12-14 According to some optional embodiments of the present invention, the protective net 6 includes a net body 63, the net body 63 includes a plurality of net strips 64, the plurality of net strips 64 are arranged at intervals along the second direction, and the net strips 64 extend along the first direction; the second direction, the first direction, and the thickness direction of the protective net 6 intersect each other.

[0112] Reference Fig.16 A limiting notch 541 is formed on the limiting crossbeam 54, and the limiting notch 541 is open along the thickness direction of the protective net 6, and at least part of the mesh strips 64 are inserted through the limiting notch 541. For example, part of the mesh strips 64 are inserted through the limiting notch 541; or, all of the mesh strips 64 are inserted through the limiting notch 541.

[0113] By at least part of the mesh strips 64 being passed through the limiting notches 541, the mesh strips 64 can be positioned in the limiting notches 541, and the limiting notches 541 can also limit the mesh strips 64 in the second direction, thereby further enhancing the stability of the protection net 6 installed on the air outlet frame 5. For example, when there are multiple limiting beams 54 arranged at intervals in the up-down direction, the multiple limiting notches 541 on the multiple limiting beams 54 can all position the protection net, thereby further enhancing the stability of the protection net 6 installed on the air outlet frame 5.

[0119] The protective net 6 is located at the downstream side of the first air guide mechanism 7. The net protrusions 65 are opposite to the first air guide louvers 73 in the thickness direction of the protective net 6, so that the wind blocking of the net protrusions 65 can be reduced, thereby increasing the air supply volume.

When the first air guide louvers 73 move as a whole to a horizontal state, the first air guide louvers 73 guide the air toward the front, and the net convex strips 65 and the corresponding first air guide louvers 73 are approximately on the same horizontal plane, reducing the obstruction of the net convex strips 65 to the airflow in the air outlet channel 50, and effectively increasing the air volume at the air outlet 110.
