When the decoration ring 13 is assembled with the air outlet plate 11, the fixing hooks 131 on the decoration ring 13 can extend into the corresponding fixing holes 111 and are matched with the fixing holes 111 in a rotating mode, and the fixing hooks 131 can be hooked on the side wall of the air outlet plate 11 when rotating relative to the fixing holes 111, so that displacement of the decoration ring 13 in the axial direction (front-rear direction) can be limited. Also, the stopper boss 132 on the bezel 13 may cooperate with the stopper 112 and limit displacement of the bezel 13 in the axial direction. Therefore, through the arrangement, the decoration ring 13 and the air outlet plate 11 can adopt a mode that the fixing hooks 131 are matched with the fixing holes 111 and the limiting bosses 132 are matched with the limiting pieces 112, so that the axial direction and the circumferential direction of the decoration ring 13 can be simultaneously limited, looseness between the decoration ring 13 and the air outlet plate 11 can be prevented, the matching structure of the decoration ring 13 and the air outlet plate 11 can be firmer, and the structural firmness of the air outlet frame component 1 can be improved.

In the specific example shown in fig. 6 to 8, a fixing hook 131 is provided on the rear end surface of the bezel 13, and the bezel 13 is connected to the air outlet plate 11 located on the rear side. The fixing hook 131 includes a first extending portion 131a and a second extending portion 131b, two ends of the first extending portion 131a are respectively connected with the decorative ring 13 and the second extending portion 131b and extend in the front-rear direction, the extending direction of the second extending portion 131b is different from the extending direction of the first extending portion 131a, and the second extending portion 131b is spaced from the rear end face of the decorative ring 13. When the fixing hooks 131 are engaged with the fixing holes 111, the second extension portions 131b are rotatably engaged with the fixing holes 111 and hooked on the rear sidewall of the air outlet plate 11, whereby the bezel 13 can be prevented from moving forward and backward with respect to the air outlet plate 11.

According to the air outlet frame component 1 of the air conditioner indoor unit 100 provided by the embodiment of the invention, the fixing holes 111 and the limiting pieces 112 are arranged on the air outlet plate 11, the fixing hooks 131 and the limiting bosses 132 are arranged on the decorative ring 13, and displacement of the decorative ring 13 in the axial direction and the circumferential direction can be limited simultaneously by adopting a mode of combining the fixing hooks 131 with the fixing holes 111 and the limiting bosses 132 with the limiting pieces 112, so that looseness between the decorative ring 13 and the air outlet plate 11 can be prevented, the matching structure of the decorative ring 13 and the air outlet plate 11 is firmer, and the structural firmness of the air outlet frame component 1 can be improved.

According to some embodiments of the present invention, the number of the limiting bosses 132 and the limiting pieces 112 may be plural, and the plurality of limiting bosses 132 and the plurality of limiting pieces 112 may be distributed at intervals in the circumferential direction of the air outlet frame 112 and be matched in a one-to-one correspondence manner, so that each limiting boss 132 may be simultaneously matched with the corresponding limiting piece 112, and may stably limit the displacement of the decorative ring 13 in the circumferential direction, so that the matching structure of the decorative ring 13 and the air outlet plate 11 may be more firm.

According to some embodiments of the present invention, the fixing holes 111 and the fixing hooks 131 may be multiple, and the fixing holes 111 and the fixing hooks 131 may be distributed at intervals in the circumferential direction of the air outlet frame 112 and are correspondingly matched one by one, so that multipoint connection between the decorative ring 13 and the air outlet plate 11 may be achieved, and each fixing hook 131 may be simultaneously matched with the corresponding fixing hole 111 to firmly limit displacement of the decorative ring 13 in the axial direction, so that the matching structure of the decorative ring 13 and the air outlet plate 11 is more firm.

As shown in fig. 6, according to some embodiments of the present invention, the limiting boss 132 may be provided with a guide slope 132a, and the guide slope 132a may be inclined to extend toward a direction approaching the central axis of the bezel 13 in a direction away from the bezel 13 (front-to-rear direction as shown in fig. 5-6), and the guide slope 132a may be slidably engaged with the limiting member 112 when the fixing hook 131 is rotatably engaged with the fixing hole 111. Specifically, the guiding slope 132a may serve as a guide for the engagement between the stopper boss 132 and the stopper 112. When the decorative ring 13 is assembled with the air outlet plate 11, the fixing hooks 131 are rotationally matched with the fixing holes 111, and at the moment, the fixing bosses are in sliding fit with the limiting pieces 112 through the guide inclined planes 132 a. Therefore, through the arrangement, the matching mode between the limiting boss 132 and the limiting piece 112 is simpler, and the assembling efficiency between the decorative ring 13 and the air outlet plate 11 can be improved.

As shown in fig. 4 and 9, in some embodiments of the present invention, the air outlet plate 11 may be provided with a placement groove 113, the limiting member 112 may be disposed on an inner wall of the placement groove 113, the limiting member 112 may be an elastic member, when the fixing hook 131 is rotationally matched with the fixing hole 111, the limiting boss 132 may press the limiting member 112 to deform in a direction away from the air outlet plate 11, and when the bezel 13 rotates in place, the limiting boss 132 may be matched with a free end 112b of the limiting member 112 to limit the bezel 13 to rotate reversely, thereby making the matching structure of the limiting boss 132 and the limiting member 112 more firm.

Specifically, the stopper 112 includes a connecting end 112a and a free end 112b connected in sequence, the connecting end 112a being connected to the inner portion Zhou Bixiang of the placement groove 113, and the free end 112b extending in the placement groove 113 and being movable back and forth with respect to the connecting end 112 a. When the fixing hook 131 is rotationally matched with the fixing hole 111, the limiting boss 132 can be abutted against the limiting piece 112. Along with the continuous rotation of the fixing hooks 131 relative to the fixing holes 111, the decorative ring 13 moves towards the direction close to the air outlet plate 11, therefore, the limiting boss 132 can press the limiting piece 112 backwards, the limiting boss 132 can move towards the direction close to the central axis of the air outlet frame 112 relative to the limiting piece 112, the limiting piece 112 elastically deforms while being in sliding fit with the limiting boss 132, and the free end 112b of the limiting piece 112 can move backwards relative to the fixed end. When the bezel 13 is mounted in place, the free end 112b of the stopper 112 can move forward under the action of the elastic force to firmly stop against the stopper boss 132. Thus, by the arrangement, the fitting structure of the decorative ring 13 and the air outlet plate 11 can be firmer.

In the specific example shown in fig. 4, the stopper 112 includes a connection end 112a and a free end 112b connected in sequence, the connection end 112a being connected to the inner portion Zhou Bixiang of the placement groove 113, and the free end 112b extending in the placement groove 113 and being movable back and forth with respect to the connection end 112 a. When the fixing hook 131 is rotationally matched with the fixing hole 111, the fixing hook 131 can rotate relative to the fixing hole 111, the decorative ring 13 moves towards the direction close to the air outlet plate 11, the limiting boss 132 can backwards press the limiting piece 112, the limiting piece 112 is elastically deformed, and the free end 112b can backwards move relative to the fixed end. As the fixing hook 131 continues to rotate relative to the fixing hole 111, the limiting boss 132 may move relative to the limiting member 112 toward a direction approaching the central axis of the air outlet frame 112. When the decorative ring 13 is installed in place, the fixing hook 131 can be hooked on the air outlet plate 11, the limiting piece 112 moves to the radial inner side of the limiting boss 132 and is located in the placing groove 113, the limiting piece 112 is separated from the guiding inclined plane 132a, and the free end 112b returns to the initial state under the action of elastic force.

Thus, not only the structural design form of the stopper 112 can be made simpler. Moreover, when the decorative ring 13 is mounted in place, the free end 112b of the limiting member 112 can rebound under the action of the elastic force, so that rebound noise can be generated, the rebound noise can play a role in prompting the decorative ring 13 to be mounted in place, and the mounting efficiency of the decorative ring 13 can be improved.

As shown in fig. 3, according to some embodiments of the present invention, the fixing hole 111 may include a first portion 111a and a second portion 111b that are connected to each other, and a radial width of the first portion 111a may be greater than a radial width of the second portion 111b, so that the fixing hole 111 may perform a good guiding function on the fixing hook 131, and assembly efficiency of the decorative ring 13 may be improved.

For example, as shown in fig. 3, the first portion 111a may have a first side wall and a second side wall disposed opposite to each other, and the first side wall is located outside the second side wall in the radial direction of the air outlet frame 112. The second portion 111b may also have a third side wall and a fourth side wall disposed opposite to each other, and the third side wall is located outside the fourth side wall in the radial direction of the air outlet frame 112. The distance between the first side wall and the second side wall is greater than the distance between the third side wall and the fourth side wall, the first side wall is located at the radial outer side of the third side wall, and the distance between the second side wall and the fourth side wall and the central axis of the air outlet frame 112 is equal. When the fixing hook 131 is rotatably engaged with the fixing hole 111, the fixing hook 131 can rotate from the first portion 111a into the second portion 111b, and the fixing hook 131 can rotate along the first sidewall and the third sidewall.

For another example, the first portion 111a may have a first side wall and a second side wall disposed opposite to each other, and the first side wall is located outside the second side wall in the radial direction of the air outlet frame 112. The second portion 111b may also have a third side wall and a fourth side wall disposed opposite to each other, and the third side wall is located outside the fourth side wall in the radial direction of the air outlet frame 112. The distance between the first side wall and the second side wall is greater than the distance between the third side wall and the fourth side wall, the distance between the first side wall and the central axis of the air outlet frame 112 is equal to the distance between the third side wall and the central axis of the air outlet frame 112, and the fourth side wall is located on the radial outer side of the second side wall. When the fixing hook 131 is rotatably engaged with the fixing hole 111, the fixing hook 131 may rotate from the second portion 111b into the first portion 111a, and the fixing hook 131 may rotate along the fourth sidewall and the second sidewall.

As shown in fig. 3, in some embodiments of the present invention, one of the sidewalls of the second portion 111b may be connected with the sidewall of the same side of the first portion 111a through a slope transition, so that the engagement between the fixing hook 131 and the fixing hole 111 may be smoother. Alternatively, one of the side walls of the second portion 111b may also be in arc surface transition with the side wall on the same side of the first portion 111 a.

According to some embodiments of the present invention, the fixing hole 111 may be formed in a circular arc shape, a radial distance between both ends of the fixing hole 111 and a central axis of the air outlet frame 112 may be different, an end of the fixing hole 111 having a large radial distance from the central axis of the air outlet frame 112 may be a distal end, and an end of the fixing hole 111 having a small radial distance from the central axis of the air outlet frame 112 may be a proximal end. When the fixing hook 131 is rotatably engaged with the fixing hole 111, the fixing hook 131 may be rotatably engaged with and rotated to the proximal end from the distal end at the fixing hole 111. Thus, by the arrangement, the design form of the fixing hole 111 is simpler, and the fixing hole 111 and the fixing hook 131 can be matched more smoothly.

As shown in fig. 2 and 7, according to some embodiments of the present invention, a portion of the wind outlet plate 11 may protrude toward a direction away from the bezel 13 to form a first stepped portion 114, and both the fixing hole 111 and the stopper 112 may be provided on the first stepped portion 114. It will be appreciated that the first step portion 114 may provide reinforcement to the air outlet plate 11 to prevent the air outlet plate 11 from being perforated to affect the structural integrity of the air outlet plate 11. Alternatively, the first stepped portion 114 may be formed in a closed loop shape, whereby not only the external appearance of the air outlet plate 11 may be more attractive, but also the reinforcing effect of the first stepped portion 114 on the air outlet plate 11 may be enhanced.

As shown in fig. 2, according to some embodiments of the present invention, two air outlet frames 112 may be provided, two air outlet frames 112 may be disposed at intervals, a portion of the air outlet plate 11 located between the two air outlet frames 112 may protrude toward a direction away from the decorative ring 13 to form a second step portion 115, and the second step portion 115 may play a role in reinforcing the air outlet plate 11, so as to further improve structural firmness of the air outlet frame component 1.

According to some embodiments of the present invention, one of the air outlet plate 11 and the bezel 13 may be provided with a screw post 133, and the other of the air outlet plate 11 and the bezel 13 may be provided with a mounting hole 114a disposed opposite to the screw post 133. That is, the air outlet plate 11 may be provided with the screw post 133 and the bezel 13 may be provided with the mounting hole 114a, or the air outlet plate 11 may be provided with the mounting hole 114a and the bezel 13 may be provided with the screw post 133. The air outlet frame member 1 may further include a fixing member which may be screwed with the screw post 133 through the mounting hole 114a. Therefore, through the arrangement, the decoration ring 13 and the air outlet plate 11 can be assembled in a mode that the fixing hole 111 is matched with the fixing clamping hook 131, the limiting boss 132 is matched with the limiting piece 112 and the fixing piece is connected with the screw post 133 through screws, so that the matching structure between the decoration ring 13 and the air outlet plate 11 is firmer.

For example, when the bezel 13 is engaged with the air outlet plate 11, the fixing hooks 131 may extend into the corresponding fixing holes 111 and be rotatably engaged with the fixing holes 111. When the fixing hook 131 is rotationally matched with the fixing hole 111, the fixing hook 131 can rotate relative to the fixing hole 111, the decorative ring 13 moves towards the direction close to the air outlet plate 11, the limiting boss 132 can backwards press the limiting piece 112, the limiting piece 112 is elastically deformed, and the free end 112b can backwards move relative to the fixed end. As the fixing hook 131 continues to rotate relative to the fixing hole 111, the limiting boss 132 may move relative to the limiting member 112 toward a direction approaching the central axis of the air outlet frame 112. When the decorative ring 13 is installed in place, the fixing hook 131 can be hooked on the air outlet plate 11, the limiting piece 112 moves to the radial inner side of the limiting boss 132 and is located in the placing groove 113, the limiting piece 112 is separated from the guiding inclined plane 132a, and the free end 112b returns to the initial state under the action of elastic force. Since the free end 112b can generate a rebound sound, the rebound sound can play a role in prompting the installation of the decorative ring 13 in place, and at the moment, the decorative ring 13 and the air outlet plate 11 can be firmly fixed together by adopting the screw connection of the fixing piece and the corresponding screw post 133 through the installation hole 114a.

The first wind wheel component is a disrotatory fan, and the second fan component is an axial flow fan. The first fan assembly comprises a first wind wheel and a second wind wheel which are opposite to each other in the front-back direction, the inclination direction of the blades of the first wind wheel is opposite to the inclination direction of the blades of the second wind wheel, the first wind wheel and the second wind wheel are guide vanes mutually in the air flow direction, so that the tangential rotation speed of air flow (namely dynamic pressure is converted into static pressure under the condition that the first wind wheel and the second wind wheel are at the same rotation speed) can be reduced or eliminated (under the condition that the first wind wheel and the second wind wheel are at different rotation speeds), the acting efficiency of the counter-rotating fan on air is improved, and the air flow passing through the two wind wheels flows towards the direction of an air outlet, thereby realizing the effect of remote air supply. It should be noted that, compared with a single cross flow fan, an axial flow fan or an oblique flow fan, the first wind wheel and the second wind wheel in the counter-rotating fan can realize the air supply of a longer distance regardless of the reverse rotation at different speeds or the reverse rotation at the same speed.

Moreover, the first wind wheel and the second wind wheel can expand the cold air conveying range under the condition of different rotating speeds. Because when one wind wheel rotates at a higher rotating speed and the other wind wheel rotates at a lower rotating speed, the wind wheel with the higher rotating speed plays a leading role, and the blade air outlet angle design based on the single-stage axial flow or diagonal flow fan deviates from the direction of the rotating shaft, the axial flow wind wheel or the diagonal flow wind wheel has a wind dispersing effect, so that the angle range of cold air flowing out from the upper air outlet frame 112 is larger, and wide-angle air supply is realized. In addition, based on the wind dispersing effect of the axial flow wind wheel or the diagonal flow wind wheel, the rotating speeds of the first wind wheel and the second wind wheel can be adjusted according to the requirement, so that the differential rotation of the first wind wheel and the second wind wheel is realized, soft wind sense or wind sense-free air supply is realized, and bad experience of direct blowing of cold wind after the cold wind flows out of the upper air outlet frame 112 is avoided. Therefore, the air conditioning indoor unit 100 according to the embodiment of the invention can realize soft air feeling or air supply without air feeling without using an air deflector with micropores, and has less air loss. It should be noted that, in order to realize wide-angle air supply and air supply without wind sense, the motor corresponding to one wind wheel is not operated, and the other wind wheel still supplies air in the forward direction towards one side of the air outlet frame 112. In addition, in order to realize wide-angle air supply and air supply without wind sense, one wind wheel can also reversely supply air to the inner side of the shell 3, and the other wind wheel can still supply air positively. The "forward air supply" is that the air flow is blown out from the air outlet frame 112 under the action of the wind wheel, and the "reverse air supply" is that the air flow is blown into the inner side of the casing 3.

According to the air conditioning indoor unit 100 provided by the embodiment of the invention, by arranging the air outlet frame component 1, the assembly efficiency of the air conditioning indoor unit 100 can be improved, and the whole structure of the air conditioning indoor unit 100 can be firmer and the operation is smoother.
