Referring to fig. 3 and 4, in some embodiments, the panel 10 includes a circular outer frame 104 and a circular inner frame 106, the inner frame 106 is disposed coaxially with the outer frame 104, and the annular holes 102 are formed between the outer frame 104 and the inner frame 106.

In this way, the outer frame 104 can serve as the outer wall of the annular hole 102 to form the air outlet duct 13 together with the air guide strips 12 to guide the air outlet of the air conditioner, and the inner frame 106 can be used to support the air guide strips 12, so that the air guide strips 12 will not fall off under the action of gravity when the panel assembly 1000 is installed on the ceiling.

In the embodiment of the present invention, the annular hole 102 is formed at the interval between the outer frame 104 and the inner frame 106, and the annular hole 102 may be the annular hole 102 which is continuously formed for a whole circle, or the annular hole 102 which is formed by a plurality of holes which are spaced apart from each other.

Specifically, the diameter of inner frame 106 is smaller than the diameter of outer frame 104, and inner frame 106 and outer frame 104 may be disposed on the same plane. In other embodiments, inner frame 106 may protrude from outer frame 104 in a direction away from the air conditioner.

In some embodiments, the panel 10 includes a plurality of connecting portions 108, the connecting portions 108 connect the outer frame 104 and the inner frame 106, the connecting portions 108 divide the annular hole 102 into a plurality of arc-shaped holes 1022, the number of the air guide strips 12 is plural, and each air guide strip 12 and a hole wall of a corresponding one of the arc-shaped holes 1022 together form an arc-shaped air outlet duct 13.

In this way, the relative position between the inner frame 106 and the outer frame 104 is fixed, and the air outlet angle can be changed by changing the position of the air guide strip 12.

Meanwhile, each air guide strip 12 and the hole wall of a corresponding arc-shaped hole 1022 together form an arc-shaped air outlet channel 13, so that each air guide strip 12 can move relatively independently, different air outlet effects can be achieved in different directions of the air conditioner, and for example, different air outlet angles in different directions can be achieved by controlling a plurality of air guide strips 12 to move in different strokes; by controlling the plurality of air guide strips 12 to move back and forth at different speeds, the inconsistency of the wind sweeping modes in different directions can be realized.

In the embodiment of the present invention, the number of the connecting portions 108 is three, and the connecting portions 108 are uniformly spaced along the circumferential direction of the inner frame 106. Thus, the connection between the outer frame 104 and the inner frame 106 is reliable, and the safety of the air conditioner is improved.

Correspondingly, in the embodiment of the present invention, the number of the wind guide strips 12 is also three, each wind guide strip 12 moves in the arc-shaped hole 1022 between two adjacent connecting portions 108, and the diameter and the arc length of each wind guide strip 12 are equal. Thus, the three air guide strips 12 can move independently, so that the air conditioner can have different air outlet angles along three directions.

Of course, in other embodiments, the number of the connecting portions 108 and the number of the air guide strips 12 may be designed according to actual use requirements.

In some embodiments, the panel assembly 1000 includes a panel rear cover 14 fixedly connected to the panel 10, an accommodating space 15 is formed between the panel 10 and the panel rear cover 14, the wind guide strip 12 is disposed in the accommodating space 15, and the panel rear cover 14 is provided with a wind outlet 16 corresponding to the annular hole 102.

The position of the air outlet 16 corresponds to the position of the annular hole 102, so that the air flow can enter the air outlet channel 13 after passing through the air outlet 16.

In some embodiments, a driving portion (not shown) for driving the air guide strips 12 to move may be further disposed in the accommodating space 15 to achieve automatic adjustment of the air outlet angle of the air outlet duct 13, the number of the driving portions may be multiple, and two ends of each air guide strip 12 may be respectively provided with one driving portion, so that the difference of the moving strokes of the air guide strips 12 can be obtained by controlling the difference of the driving powers of the multiple driving portions, and the air conditioner may have different air outlet angles in different directions.

In some embodiments, the driving portion may drive the gear to rotate and drive the rack to move, and the rack drives the wind-guiding strip 12 to move. Of course, in other embodiments, the specific implementation of the driving section for driving the air guide strips 12 may be other options, and is not limited herein.

Referring to fig. 5 and 6, in the embodiment of the present invention, the inside of the wind-guiding strip 12 is designed to be hollow.

Therefore, materials for manufacturing the air guide strips 12 are saved, the air guide strips 12 are light and convenient, the air guide strips 12 are easily driven by the driving part, and energy for driving the air guide strips 12 is saved.

Referring to fig. 7 and 8, in some embodiments, the panel assembly 1000 includes a plurality of guide rods 17, the guide rods 17 are fixedly disposed on the air guide bars 12, the guide rods 17 are provided with guide grooves 172, the panel rear cover 14 includes a plurality of guide post sets 142, and the guide post sets 142 penetrate through the guide grooves 172 to guide the air guide bars 12 to move.

In this way, the guide column group 142 is matched with the guide groove 172 to guide the movement of the air guide bar 12, so that the movement of the air guide bar 12 is stable and the movement track of the air guide bar 12 is easily controlled.

Referring to fig. 5 and 6, specifically, the guide rod 17 extends into the hollow portion of the wind guide bar 12 and is fixedly connected to the wind guide bar 12, the guide groove 172 is formed in the middle portion of the guide rod 17, and the length direction of the guide groove 172 is the same as the moving direction of the whole wind guide bar 12. In this manner, the guide post set 142 can guide the wind strip 12 to move along the radial direction of the annular hole 102 by cooperating with the guide slot 172.

Preferably, the inner wall of the guide slot 172 and the outer wall of the guide column set 142 are smooth surfaces. In this way, the frictional force between the guide post group 142 and the guide groove 172 is reduced, and the air guide bar 12 is easily driven to move.

In the embodiment of the present invention, each wind guide bar 12 is fixedly connected to two guide rods 17, the two guide rods 17 are arranged in parallel, and the length directions of the two guide grooves 172 are parallel. Correspondingly, each wind guide bar 12 is matched with the two guide grooves 172 by the two guide column groups 142.

Referring to fig. 9, in some embodiments, the guide slot 172 includes a first position-limiting end 1722, the guide post set 142 includes a first guide post 1422, and the first guide post 1422 is used for engaging the first position-limiting end 1722 to limit the maximum moving stroke of the air guide bar 12 close to the inner frame 106 along the radial direction of the annular hole 102.

Thus, the first guiding column 1422 cooperates with the first position-limiting end 1722 to limit the maximum moving stroke of the wind-guiding strip 12 close to the inner frame 106 along the radial direction of the annular hole 102, so that the wind-guiding strip 12 can move in the annular hole 102 all the time, and the wind-guiding strip 12 is prevented from separating from the annular hole 102 and the wind outlet angle cannot be changed.

Specifically, the first limiting end 1722 is disposed at one end of the guiding rod 17 extending into the hollow portion of the air guiding bar 12, and as the air guiding bar 12 gradually approaches the inner frame 106 along the radial direction of the annular hole 102, the first limiting end 1722 gradually approaches the first guiding post 1422 and is finally clamped on the first guiding post 1422, so that the air guiding bar 12 can no longer approach the inner frame 106. At this time, the air outlet angle of the air conditioner is substantially perpendicular to the plane where the annular hole 102 is located, and in the embedded air conditioner of the embodiment of the present invention, when the embedded air conditioner is installed on a ceiling, the air outlet direction is substantially in a vertical downward direction.

In the present embodiment, the first guiding post 1422 is cylindrical, and the first position-limiting end 1722 includes a cylindrical inner wall. Thus, the friction between the cylindrical first guiding post 1422 and the guiding slot 172 is smaller, and the matching degree between the first guiding post 1422 and the first position-limiting end 1722 is higher. Of course, in other embodiments, the specific shapes of the first guiding post 1422 and the first position-limiting end 1722 can be selected according to the actual requirement.

Referring to fig. 10 and 11, in some embodiments, the guide slot 172 includes a second position-limiting end 1724, the guide post set 142 includes a second guide post 1424, and the second guide post 1424 is used for engaging the second position-limiting end 1724 to limit the maximum moving stroke of the air guide bar 12 away from the inner frame 106 along the radial direction of the annular hole 102.

Thus, the second guiding column 1424 cooperates with the second position-limiting end 1724 to limit the maximum moving distance of the wind-guiding strip 12 along the radial direction of the annular hole 102 away from the inner frame 106, so as to prevent the wind-guiding strip 12 from closing the annular hole 102 and preventing the air conditioner from smoothly discharging air.

Specifically, the second limiting end 1724 is disposed at an end of the guiding rod 17 away from the air guiding bar 12, and as the air guiding bar 12 gradually gets away from the inner frame 106 along the radial direction of the annular hole 102, the second limiting end 1724 gradually gets close to the second guiding post 1424 and finally is clamped on the second guiding post 1424, so that the air guiding bar 12 can not get away from the inner frame 106 any more. At this time, the air outlet angle of the air conditioner is substantially parallel to the plane of the annular hole 102, and in the embedded air conditioner according to the embodiment of the present invention, when the embedded air conditioner is installed on the ceiling, the air outlet direction is substantially horizontal.

In one embodiment, the second guiding post 1424 is cylindrical, and the second limiting end 1724 includes a cylindrical inner wall. Thus, the friction between the cylindrical second guiding post 1424 and the guiding slot 172 is smaller, and the matching degree between the second guiding post 1424 and the second limiting end 1724 is higher. Of course, in other embodiments, the specific shapes of the second guiding column 1424 and the second limiting end 1724 can be selected according to actual needs.

In some embodiments, the inner frame 106 defines air inlet openings 1062 spaced from the annular opening 102, and the panel assembly 1000 includes an air inlet grille 18 fixedly attached to the inner frame 106, the air inlet grille 18 covering the air inlet openings 1062.

Thus, the outside air can enter the air conditioner through the air inlet grille 18 and the air inlet 1062.

In the embodiment of the present invention, the air inlet grille 18 is formed with the grille holes 182 having long strips, air can enter the air conditioner through the grille holes 182, and the grille holes 182 can block foreign matters from entering the air conditioner, such as paper scraps having a large volume.

Specifically, the inner frame 106 and the air intake grille 18 may be connected by a snap-fit connection.

Thus, the connection between the air inlet grille 18 and the inner frame 106 is simple and reliable, and the air inlet grille 18 is easy to disassemble and assemble.

Of course, in other embodiments, the air intake grille 18 and the inner frame 106 may be connected in other ways.

In some embodiments, the wall of the annular hole 102 is formed with a first wind guiding surface 1042, the wind guiding strip 12 is formed with a second wind guiding surface 122, the wind guiding surface 13 is formed between the first wind guiding surface 1042 and the second wind guiding surface 122, and the wind guiding strip 12 moves to make the second wind guiding surface 122 approach or separate from the first wind guiding surface 1042 to change the wind outlet angle of the wind guiding channel 13.

In this way, the first air guiding surface 1042 is fixed, and the air outlet angle can be changed by moving the air guiding strip 12, that is, moving the second air guiding surface 122, which is simple to operate.

In the embodiment of the present invention, the first air guiding surface 1042 is formed on the frame 104.

Specifically, the first air guiding surface 1042 and the second air guiding surface 122 are both designed to be streamlined, so that friction between air and the first air guiding surface 1042 and the second air guiding surface 122 is small, and influence on air outlet force of the air conditioner is reduced.

The air conditioner according to an embodiment of the present invention includes the panel assembly 1000 according to any one of the above embodiments.

So, in the panel components 1000 of air conditioner, air guide strip 12 forms curved exhaust duct 13 with the pore wall of annular hole 102, and the air conditioner of using panel components 1000 can realize the air supply angle bigger than square air outlet, and through the radial movement with air guide strip 12 along annular hole 102, can change the air-out angle of exhaust duct 13 simultaneously for the air-out effect of air conditioner is better.
