Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air outlet control method. Background Art

[0002] At present, the indoor unit of the air conditioner has multiple functions such as cooling and heating. In terms of air supply method, the general indoor unit uses a guide plate to change the direction of air discharge at the air outlet to achieve the effect of sweeping air.

[0003] In some air conditioning structures in the prior art, a conversion plate is provided inside the air conditioner to guide the airflow to different air outlets for discharge, thereby achieving upper exhaust or lower exhaust, or achieving front exhaust or side exhaust.

[0004] For example, Chinese patent application number 201820334363.2 discloses an air-conditioning indoor unit, which includes a shell, an air duct, an electromagnetic component and a wind direction conversion plate. The shell has an upper air outlet and a lower air outlet. The electromagnetic component is arranged on the lower surface of the upper air duct wall of the air duct. The wind direction conversion plate is arranged in the air duct, and a magnetically absorbable material layer is attached to its upper surface. The plate is configured to rotate upward to a rotation position when the electromagnetic component is energized, and return to the initial position when the electromagnetic component is de-energized.

[0005] The structure of the air conditioner indoor unit is that when the electromagnetic component is energized, the electromagnetic component magnetically attracts the wind direction conversion plate and rotates it upward, realizing the upward blowing mode; when the electromagnetic component is de-energized, the wind direction conversion plate rotates downward under the action of its own weight, realizing the downward blowing mode.

[0006] Therefore, the wind direction conversion plate cannot stay at any position between the two extreme rotation positions of the wind direction conversion plate, so that the air conditioner indoor unit can only perform a separate upward blowing mode or downward blowing mode, and cannot achieve air outlet adjustment in a single air outlet direction, or achieve air outlet in two directions at the same time. Therefore, the use of the air outlet structure of this air conditioner is limited.

[0007] Therefore, it is necessary to propose a new air-conditioning air outlet control scheme. Summary of the Invention

DETAILED DESCRIPTION

[0061] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0062] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0063] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0064] Example 1

[0065] See Figures 1 to 12 The present invention discloses an air conditioner 1, which includes a heat exchanger 11 and an air outlet system 2, wherein the air outlet system includes a shell 21, a fan 22 and an improved air duct structure 3, wherein an air inlet duct 211 and an air outlet duct 212 are provided on the shell 21, and the fan 22 is installed in the shell 21 and is located between the air inlet duct 211 and the air outlet duct 212 to provide power for the air flow, that is, to transport the air flow entering from the air inlet duct 211 to the air outlet duct 212.

[0066] The heat exchanger 11 is arranged in the shell 21 of the air outlet system 2 and is located in the air outlet duct 212 of the air outlet system 2. It is used to perform heat exchange on the air flow, heat or cool the air entering from the air inlet duct 211, and discharge it from the air outlet duct 212 to realize the heating or cooling process.

[0067] The housing 21 is further provided with a filter 2111 at the entrance of the air inlet channel 211 for filtering the intake air.

[0068] The air duct structure 3 is provided in the air outlet channel 212 for distributing the discharge of air flow.

[0069] In this embodiment, the air duct structure 3 includes a fixed air duct wall 31 and a movable air duct wall assembly 32 , wherein the fixed air duct wall 31 is provided with two air outlets 311 facing different directions, and two air outlets 311 are provided.

[0070] The movable air duct wall assembly 32 is connected to the fixed air duct wall 31 and is located on one side of one of the air outlets 311 , and is used to adjust the opening size of the corresponding air outlet 311 .

[0071] See Figures 1 to 5 In this embodiment, the movable air duct wall assembly 32 includes a driving device 321 and a telescopic panel 322, wherein the telescopic panel 322 is movably connected to the fixed air duct wall 31 to form an air guide inner wall (not marked in the figure), and the driving device 321 is connected to the telescopic panel 322 and can drive at least a portion of the telescopic panel 322 to move, so as to adjust the opening size of the telescopic panel 322 closed to the corresponding air outlet 311, that is, to adjust the opening size of the corresponding air outlet 311.

[0072] It should be noted that the telescopic panel 322 can be a flexible panel, a rigid panel, or a combination of a flexible panel and a rigid panel.

[0073] The beneficial effect of adopting this structure is that, since the telescopic panel 322 can be extended or retracted as the driving device 321 drives, the telescopic panel 322 can also adjust the direction of airflow. For example, when the telescopic panel 322 adjusts the opening of the corresponding air outlet 311 to be smaller, the telescopic panel 322 can guide the airflow to other air outlets 311, thereby reducing the airflow gathering at the air outlet 311 with a smaller opening and reducing the possibility of noise generation; and when the telescopic panel 322 adjusts the opening of the corresponding air outlet 311 to be larger, the telescopic panel 322 can correspondingly guide more airflow to the air outlet 311, thereby increasing the air output. Thus, further, the airflow rate allocated to the air outlet 311 can be adjusted according to the opening size of the air outlet 311, so that the flow path distribution of the airflow inside the air duct structure 3 is more reasonable and efficient, which is conducive to reducing the generation of vibration and noise; furthermore, the telescopic panel is retractable, which is convenient for the storage of the air outlet during the opening process, reducing the impact on the air output.

[0074] In the figure, P and Q indicate the inlet airflow direction and the outlet airflow direction respectively.

[0075] As a preferred embodiment, an active node 33 is provided at one end of the telescopic panel 322 or between its two ends, and the driving device 321 is connected to the active node 33. The driving device 321 drives the active node 33 to move, thereby achieving the purpose of driving the telescopic panel 322 to move and adjusting the opening size of the corresponding air outlet 311.

[0076] See Figures 4 and 5In this embodiment, the telescopic panel 322 includes a flexible roller blind 34 provided on one side of the air outlet 311. The driving device 321 includes a reel assembly 35 for reeling in the flexible roller blind 34 and a movable driving assembly for driving the movable 33 to move. One end of the flexible roller blind 34 is fixed to the fixed air duct wall 31, and the other end is connected to the reel assembly 35. The movable node 33 is a movable rod (not marked in the figure) provided between the two ends of the flexible roller blind 34. The movable rod is connected to the movable driving assembly and is connected to the flexible roller blind 34. The surfaces of the rolling curtain 34 are in contact with each other; thus, when the mobile driving assembly drives the movable rod to move, the winding shaft assembly 35 cooperates with the action of the mobile driving assembly to wind up the flexible rolling curtain 34. Specifically, the winding shaft assembly 35 applies a winding force to the flexible rolling curtain 34 to keep the flexible rolling curtain 34 taut. The tensioned flexible rolling curtain 34 is equivalent to a gate that closes the air outlet 311, and can block the air outlet 311. The mobile driving assembly drives the movable rod to move, and can adjust the size of the air outlet 311 closed by the flexible rolling curtain 34.

[0077] Furthermore, it should be noted that, in order to ensure the sealing effect of closing the air outlet 311, the flexible roller blind 34 is made of an airtight flexible material, such as polyester fiber cloth.

[0078] The structure of the winding shaft assembly 35 includes a rotating shaft (not shown in the figure) and a power component (not shown in the figure) that drives the rotating shaft to rotate. The power component can be a motor or a torsion spring. One end of the flexible roller blind 34 is fixed to the rotating shaft, and tensioning and winding are achieved under the drive of the power component.

[0079] The surface where the movable rod contacts the flexible rolling curtain 34 is smoothed.

[0080] Preferably, the movable rod is configured to be rotatable, that is, it can rotate as the flexible roller blind 34 extends or contracts, so that the contact between the movable rod and the flexible roller blind 34 is replaced by rolling friction instead of sliding friction, reducing damage to the flexible roller blind 34 and extending its service life.

[0081] Alternatively, in other solutions, a roller or a ball may be provided on the movable rod, and the roller or the roller may abut against the surface of the flexible rolling curtain 34 , thereby also achieving the purpose of reducing wear on the flexible rolling curtain 34 .

[0082] See Figures 1-3 In this embodiment, the fixed air duct wall 31 includes a side wall 312 and an inner wall 313. The side walls 312 are located on both sides of the inner wall 313. The air outlet 311 is opened on the inner wall 313. The movable air duct wall component 32 is also arranged on the inner wall 313. The side wall 312 is also provided with a guide component 36 that provides movement guidance for the movable node 33.

[0083] The flexible rolling curtain 34 is fixed to the inner walls 313 on both sides of the side wall 312 via a connecting plate 341 .

[0084] Further, as a preferred embodiment, in this embodiment, the guide assembly 36 includes a slide groove 361 arranged on the side wall 312, and the movable node 33 is slidingly connected to the slide groove 361. In this embodiment, the movable rod is slidingly matched with the slide groove 361 and slides in the slide groove 361.

[0085] Furthermore, the sliding groove 361 may be arranged along an air outlet direction perpendicular to the air outlet 311 ; this arrangement is the optimal arrangement, which can simplify the installation structure.

[0086] In other embodiments, the opening direction of the slide groove 361 can also be at an inclined angle to the air outlet direction of the air outlet 311; through such a setting, the purpose of enabling the telescopic panel 322 to change the size of the opening of the air outlet 311 when the active node 33 moves along the slide groove 361 can be achieved.

[0087] In addition, in other possible implementations, the guide component 36 may also be a slide rail. The slide rail may be a conventional slide rail on the market, and is connected to the active node 33 via the slide rail, thereby providing a movement guide for the active node 33 .

[0088] See Figures 4 and 5 In this embodiment, the driving device 321 includes a driving motor 3211 and a connecting rod mechanism 3212, wherein the connecting rod mechanism 3212 includes a crank 32121 and a connecting rod 32122, the driving motor 3211 is connected to the crank 32121 and drives it to rotate, one end of the connecting rod 32122 is hinged to the crank 32121, and the other end is hinged to the movable rod; thus, by driving the connecting rod 32122 to drive the movable rod to move, the telescopic panel 322 can be extended or retracted, that is, the flexible roller blind 34 can be extended or retracted, and this structure has a smaller volume when retracted, thereby ensuring that the air outlet of the air outlet 311 is blocked as little as possible in the retracted state, so that the air outlet of the air outlet 311 is not blocked.

[0089] In other possible implementations, the driving device 321 may also be a conventional telescopic rod, such as an electric telescopic rod.

[0090] Furthermore, as a preferred embodiment, an air guide plate assembly 23 and an annular air outlet structure 24 are also provided on the shell 21. The air guide plate assembly 23 and the annular air outlet structure 24 are connected to different air outlets 311 in the air duct structure 3, wherein the air guide plate assembly 23 is used to achieve fixed-angle air outlet or swept air, and the annular air outlet structure 24 is used for annular air outlet, which reduces the airflow directly hitting the human body, moderates the air outlet, and achieves the purpose of comfort.

[0091] Furthermore, the air guide plate assembly 23 and the annular air outlet structure 24 are arranged on different sides of the housing 21 .

[0092] Further, as a preferred embodiment, Figure 1 As shown, in this embodiment, the annular air outlet structure 24 is provided at the front end of the housing 21 , that is, the right side in the figure.

[0093] See Figure 9 As a possible implementation manner, the annular air outlet structure 24 is provided on the side of the shell 21 .

[0094] Through such an arrangement, compared with the forward air outlet from the front end of the shell, the circular air outlet from the side can further mitigate the air outlet and achieve a windless feeling.

[0095] Further, as a preferred embodiment, see Figure 1 In this embodiment, the air guide plate assembly 23 is arranged at the lower end of the shell 21.

[0096] In other possible implementations, the air deflector assembly 23 may also be disposed at the upper end or side of the housing 21 .

[0097] The setting of the air guide plate assembly 23 and the annular air outlet structure 24 further increases the diversity of the air outlet mode, and can realize sweeping air and annular air outlet. Combined with the air duct structure 3, when the air duct structure 3 is configured with different air outlets 311 to discharge air, the air guide plate assembly 23 and the annular air outlet structure 24 can be combined to meet different usage needs.

[0098] For example, Figure 1 、 Figures 10-12 As shown, the air duct structure 3 is configured so that when only the air outlet 311 located on the lower side of the housing 21 is discharged, the wind guide plate assembly 23 adjusts the angle of the wind outlet downward, or the wind guide plate assembly 23 can swing periodically to achieve wind sweeping;

[0099] like Figure 10 As shown, when the air duct structure 3 is configured so that the air outlets 311 located on the lower side and right side of the shell 21 discharge air at the same time, if the air guide plate assembly 23 is closed, the air outlet 311 on the lower side of the shell 21 is closed. At this time, the annular air outlet structure 24 realizes an annular air discharge to the right side of the shell 21; Figure 1 As shown, if the air guide plate assembly 23 is operated simultaneously, the air outlet angle adjustment and air sweeping on the lower side of the shell 21 can be achieved, and the annular air outlet on the right side of the shell 21 can also be achieved;

[0100] like Figure 12 As shown, if the air guide plate assembly 23 is closed and the variable air duct wall assembly closes the corresponding air outlet 311, the air outlet 311 is closed and the air duct system stops discharging air.

[0101] Furthermore, the annular air outlet structure 24 includes an outer frame 241 and a center panel 242, wherein the outer frame 241 and the center panel 242 are both fixed to the shell 21, the center panel 242 is arranged within the range of the outer frame 241, and is connected and fixed to the outer frame 241 by a fixing rod 2421, and an air outlet gap 243 is formed between the circumference of the center panel 242 and the circumference of the outer frame 241, and a gap is maintained between the plate surface of the center panel 242 and the surface of the outer frame 241 to form an internal cavity 244 connected to the air outlet 311, so that the airflow discharged from the air outlet 311 is transported to the air outlet gap 243 on the circumferential side.

[0102] Furthermore, the air deflector assembly 23 includes an air deflector body 231 and an air deflector drive component 232. The air deflector body 231 is rotatably connected to the shell 21 and can move relative to the shell 21 to open or close the corresponding air outlet 311. The air deflector drive component 232 includes a rotating drive element (not shown in the figure) for driving the air deflector body 231 to rotate and a moving drive element (not shown in the figure) for driving the air deflector body 231 to move.

[0103] like Figure 10 、 Figure 12 As described above, the air deflector body 231 is movably connected to the shell 21 in the vertical direction and is vertically raised and lowered by the moving driving element. When the air deflector body 231 is raised, the air outlet 311 can be closed, and when the air deflector body is lowered, the air outlet 311 can be opened.

[0104] The mobile drive element can adopt an electric push rod.

[0105] Alternatively, the mobile driving element can be configured to include a motor, a gear, and a rack, wherein a driving rack is fixed on the air guide plate, a motor is provided on the shell 21, and a gear meshing with the driving rack is fixed on the rotating shaft of the motor. Thus, the gear rack is driven by the motor to operate, and the lifting and lowering of the air guide plate body 231 can also be achieved.

[0106] The rotation driving element may be a servo motor.

[0107] In other possible embodiments, the rotating drive element can also be configured to include a motor and a synchronous belt transmission assembly. The synchronous belt transmission assembly can also be replaced by a gear transmission assembly. The power of the motor is transmitted to the air deflector body 231 through the synchronous belt transmission assembly, thereby achieving the purpose of driving the air deflector body 231 to rotate.

[0108] To facilitate installation, the air deflector body 231 can be rotatably set on a lifting frame 2311, the lifting frame 2311 is connected to the movable driving element, and the rotating driving element is set on the lifting frame 2311 and connected to the movable part, thereby driving the air deflector body 231 to rotate relative to the lifting frame 2311, that is, driving the air deflector body 231 to rotate relative to the shell 21, thereby adjusting the air outlet direction of the air outlet 311.

[0109] Furthermore, the air guide plate body 231 can block another air outlet 311 under the driving of the rotating driving element, such as Figure 11 As shown, when the air guide plate body 231 rotates to a vertical position, the air guide plate body 231 closes the air outlet 311 on the right side.

[0110] Furthermore, the air guide plate body 231 abuts against the active node 33 in the air duct structure 3 to form a baffle that closes the air outlet 311, thereby closing the air outlet of the right air outlet 311 and achieving vertical downward air outlet of the lower air outlet 311.

[0111] Air conditioner 1 also includes an insulation layer 12 fixedly mounted on central panel 242 and a display assembly 13 fixed to central panel 242. Insulation layer 12 is used to insulate central panel 242 and reduce condensation. Display assembly 13 primarily includes a display screen and a circuit board, and is used to display various parameters of air conditioner 1, such as temperature and humidity.

[0112] The working principle of the movable air duct wall assembly in this embodiment is:

[0113] When it is necessary to reduce the air volume of the air outlet, the driving device 321 drives the movable rod to move downward along the slide groove 361 in the direction shown in the figure. When the movable rod moves downward, the flexible roller curtain 34 is driven to tilt and extend downward. The surface of the flexible roller curtain 34 on one side of the movable rod (the surface of the flexible roller curtain 34 on the right side of the movable rod in the figure) blocks the corresponding air outlet 311, and the surface of the flexible roller curtain 34 on the other side tilts the airflow to the open air outlet 311, thereby reducing the air volume of the air outlet 311 set at the corresponding movable air duct wall component.

[0114] When it is necessary to increase the air volume of the air outlet 311 set at the corresponding movable air duct wall component and realize simultaneous air outlet of the two air outlets 311, the driving device 321 drives the movable rod to move upward in the slide groove 361 as shown in the figure. During the upward movement of the movable rod, the winding shaft assembly 35 retracts the flexible roller curtain 34 accordingly to keep the flexible roller curtain 34 tensioned, so that the flexible roller curtain 34 opens the corresponding air outlet 311, realizing simultaneous air outlet of the two air outlets 311, and the driving device 321 drives the movable rod to stop at any position of the slide groove 361, and can maintain a fixed opening size, thereby maintaining the air volume of the corresponding air outlet 311, and can realize the adjustment and control of the air volume size of the corresponding air outlet 311.

[0115] Therefore, the air conditioner 1 of the present invention can realize a variety of air outlet modes according to actual application needs in the heating or cooling mode, such as Figure 1 The lower air outlet 311 shown in the figure discharges air and annular air, as shown in the figure Figure 10 The figure shows only the annular air outlet. Figure 11 The lower air outlet 311 shown discharges air vertically, or the lower fixed-angle air discharge and sweeping air are controlled only by the air guide plate assembly 23, making the user's use more comfortable and meeting more diverse usage needs.

[0116] It should be pointed out that this embodiment takes the setting of two air outlets as an example. In other embodiments, if one air outlet or more than three air outlets are set, technical personnel in this field can also perform adaptive design according to the similar settings of this embodiment to achieve the purpose of adjusting the air volume of the air outlet. Under the adopted air duct structure, structures that do not have two air outlets should also fall within the scope of protection of the present invention.

[0117] Example 2

[0118] Based on Example 1, the difference between this embodiment and Example 1 is that:

[0119] See Figure 6 The telescopic panel 322 includes two winding shaft assemblies 35, and the two ends of the flexible roller blind 34 are respectively connected to two different winding shaft assemblies 35; thus, when the mobile driving assembly drives the movable rod to move, the two winding shaft assemblies 35 can be wound or unwound at the same time, so that the tension of the flexible roller blind 34 is better and the sealing effect of the sealed air outlet 311 is better.

[0120] Example 3

[0121] See Figure 7Based on Example 1, the difference between this embodiment and Example 1 is only that, in this embodiment, the structure of the telescopic panel 322 is: one end of the flexible roller blind 34 is connected to the winding shaft assembly 35, and the other end is the active node 33. The mobile driving assembly is connected to the active node 33 to drive the active node 33 to move, thereby cooperating with the winding and unwinding of the winding shaft assembly 35 to achieve the adjustment of the opening value of the air outlet 311.

[0122] The working principle of this embodiment differs from that of embodiment 1 in that one end of the flexible roller curtain 34 driven by the driving device 321 moves, thereby driving the flexible roller curtain 34 to expand or contract, thereby controlling the size of the opening blocked by the flexible roller curtain 34 and controlling the opening size of the corresponding air outlet 311, thereby adjusting the air output.

[0123] Specifically, when the mobile drive assembly drives one end of the flexible rolling curtain 34 to move and unfold the flexible rolling curtain 34, the area covered by the flexible rolling curtain 34 on the air outlet 311 is increased, thereby reducing the air flow from the air outlet 311. In addition, when the mobile drive assembly drives the flexible rolling curtain 34 to unfold, the inclination angle formed by its surface and the fixed air duct wall 31 changes, and the inclination angle of the air guide inner wall also changes, thereby reducing the air flow directed to the air outlet 311.

[0124] On the contrary, when the mobile driving component drives one end of the flexible roller curtain 34 to move and shrink the flexible roller curtain 34, the area of ​​the air outlet 311 blocked by the flexible roller curtain 34 is reduced, thereby increasing the air output of the air outlet 311, and the inclination angle formed by the surface of the flexible roller curtain 34 and the fixed air duct wall 31 changes, even if the inclination angle of the air guide inner wall changes, the air flow directed to the air outlet 311 is increased.

[0125] Thus, the opening value of the corresponding air outlet 311 is adjusted by the movable air duct wall component 32 .

[0126] Example 4

[0127] See Figure 7 Based on Example 3, the only difference between this embodiment and Example 3 is that the mobile driving component of the driving device 321 is a driving telescopic plate 3213, and the driving telescopic plate 3213 includes a fixed end 32131 and a telescopic end 32132 that is telescopic relative to the fixed end 32131, wherein the fixed end 32131 is connected to the fixed air duct wall 31, and the telescopic end 32132 is connected to the active node 33; the fixed end 32131 and the telescopic end 32132 are both plates, which can block the air outlet 311 to achieve shielding of the opening.

[0128] The telescopic structure of the telescopic end 32132 and the fixed end 32131 can be configured to include a motor and a gear rack structure, that is, a gear is provided on the telescopic end 32132 (or the fixed end 32131), and a rack is provided on the fixed end 32131 (or the telescopic end 32132). The motor drives the gear to operate, driving the rack to move in a straight line, thereby causing the telescopic end 32132 and the fixed end 32131 to move relative to each other to achieve telescopic and retracting.

[0129] Of course, an electric push rod may also be used to drive the telescopic end 32132 to move relative to the fixed end 32131 .

[0130] Furthermore, in this embodiment, the fixed end 32131 is fixed to the fixed air duct wall 31, and the telescopic direction of the driving telescopic plate 3213 is along the opening direction of the slide groove 361, so that the driving telescopic plate 3213 can fit with the side of the air outlet 311 to form a better sealing effect.

[0131] In other embodiments, the fixed end 32131 can also be hinged to the fixed air duct wall 31, that is, the extension and retraction direction of the driving telescopic plate 3213 can be set to be not parallel to the direction of the slide groove 361. On the premise that the slide groove 361 provides guidance for the movable rod, the extension and retraction of the driving telescopic plate 3213 can also achieve the above-mentioned purpose of the invention, that is, to achieve the guidance of the airflow and the adjustment of the opening size of the corresponding air outlet 311.

[0132] The working principles of this embodiment differ from those of embodiment 3 in that:

[0133] In the process of driving the telescopic plate 3213 to extend or shorten, on the one hand, the flexible roller curtain 34 can be extended or contracted, and the airflow is guided by the flexible roller curtain 34; on the other hand, the driving telescopic plate 3213 itself can form a shield for the air outlet 311, thereby controlling the opening size of the air outlet 311. Therefore, the cooperation between the flexible roller curtain 34 and the driving telescopic plate 3213 can realize the guidance of the airflow and the adjustment of the opening size of the corresponding air outlet 311.

[0134] Example 5

[0135] See Figure 8 Based on Example 3 or Example 4, the only difference between this embodiment and Example 3 or Example 4 is that, in this embodiment, the telescopic panel 322 is a telescopic plate assembly 37, one end of the telescopic plate assembly 37 is connected to the fixed air duct wall 31, and the other end is an active node 33.

[0136] Specifically, the telescopic plate assembly 37 includes a fixed plate 371 and a movable plate 372. The movable plate 372 can move relative to the fixed plate 371 to achieve telescoping. One of the fixed plate 371 and the movable plate 372 is connected to the fixed air duct wall 31, and an active node 33 is provided at one end of the other for connecting to the mobile drive assembly of the drive device 321 and moving under the drive of the mobile drive assembly.

[0137] In this embodiment, the movable plate 372 is connected to the fixed air duct wall 31 , and the fixed plate 371 is connected to the driving device 321 .

[0138] Furthermore, since the telescopic plate assembly 37 will swing in an angular direction during the movement of extending and closing the air outlet 311 under the drive of the driving device 321 , the movable plate 372 needs to be arranged to be hinged to the fixed air duct wall 31 .

[0139] The working principle of this embodiment differs from the working principle of Embodiment 3 or 4 in that:

[0140] The telescopic plate assembly 37 replaces the retractable flexible roller blind 34 as the telescopic panel 322. When the mobile driving assembly drives the active node 33 to move, it can drive the telescopic plate assembly 37 to extend or contract, and the fixed plate 371 and the movable plate 372 of the telescopic plate assembly 37 can form a movable air duct wall to guide the airflow and cooperate with the adjustment of the opening size of the air outlet 311.

[0141] Specifically, when the mobile driving assembly drives the telescopic plate assembly 37 to move and unfold the telescopic plate assembly 37, similar to a flexible rolling curtain, after the telescopic plate assembly 37 is unfolded, the area blocked by the air outlet 311 is increased, thereby reducing the opening value of the air outlet 311, that is, reducing the air output of the air outlet 311, and the inclination angle formed by the surface of the telescopic plate assembly 37 and the fixed air duct wall 31 changes, that is, the inclination angle of the air guide inner wall changes, thereby reducing the air flow directed to the air outlet 311;

[0142] On the contrary, when the mobile driving assembly drives the telescopic plate assembly 37 to move and drives the telescopic plate assembly 37 to retract, the area blocked by the air outlet 311 is reduced, thereby increasing the opening value of the air outlet 311, that is, increasing the air output of the air outlet 311, and the inclination angle formed by the surface of the telescopic plate assembly 37 and the fixed air duct wall 31 changes, that is, the inclination angle of the air guide inner wall changes, thereby increasing the air flow directed to the air outlet 311.

[0143] Example 6

[0144] Based on Example 1, the difference between this embodiment and Example 1 is that, in this embodiment,

[0145] The air outlet 311 is arranged on the side of the fixed air duct wall 31, the telescopic panel 322 includes a flexible roller curtain 34, and the driving device 321 includes a winding shaft assembly 35 for winding the flexible roller curtain 34, wherein the winding shaft assembly 35 is fixed relative to the fixed air duct wall 31, one end of the flexible roller curtain 34 is fixed to the fixed air duct wall 31, and the other end is connected to the winding shaft assembly 35, and a counterweight rod (not marked in the figure) is also provided between the two ends of the flexible roller curtain 34, and the counterweight rod is movably arranged in the vertical direction relative to the fixed air duct wall 31, and the counterweight rod is in contact with the surface of the flexible roller curtain 34.

[0146] In this embodiment, as the reel assembly 35 cooperates with the unwinding of the flexible curtain 34, the weight of the counterweight rod stretches the flexible curtain 34 downward, causing the flexible curtain 34 to extend, thereby changing the inclination angle between the flexible curtain 34 and the fixed air duct wall 31, adjusting the inclination angle of the air guide inner wall, and increasing the area of ​​the air outlet 311 covered by the flexible curtain 34, thereby reducing the opening value of the air outlet 311.

[0147] When the flexible roller curtain 34 is retracted, the gravity of the counterweight rod is overcome by the reeling shaft assembly 35, and the flexible roller curtain 34 is retracted, thereby causing the telescopic panel 322 to shrink and swing relative to the fixed air duct wall 31, changing the inclination angle between the flexible roller curtain 34 and the fixed air duct wall 31, adjusting the inclination angle of the air guide inner wall and reducing the area of ​​the air outlet 311 blocked by the flexible roller curtain 34, increasing the opening value of the air outlet 311 and adjusting the air flow direction and air volume.

[0148] In other possible implementations, the counterweight rod may also be configured to move up and down relative to the fixed air duct wall 31 in a direction forming an inclination angle with the vertical direction.

[0149] Example 7

[0150] See Figures 13-15 Based on the above embodiments, the difference between this embodiment and the above embodiments is that:

[0151] The fixed air duct wall 31 includes two first fixed walls 3101 and a second fixed wall 3102 that are opposite and spaced apart. Two groups of movable air duct wall components 32 are provided, wherein one group of movable air duct wall components 32 is connected to the first fixed wall 3101 to form a first air guide wall (not marked in the figure), and the other group of movable air duct wall components 32 is connected to the second fixed wall 3102 to form a second air guide wall (not marked in the figure). The first air guide wall and the second air guide wall form a ventilation flow channel (not marked in the figure) for air flow; thus, the two groups of movable air duct wall components 32 can be adjusted independently or simultaneously to adjust the flow direction and flow area of ​​the ventilation flow channel.

[0152] Furthermore, in this embodiment, an air outlet 311 is provided at the bottom and side of the fixed air duct inner wall 313, wherein one group of movable air duct wall components 32 is provided on one side of the bottom air outlet 311, thereby adjusting the airflow direction and the size of the air outlet from the bottom air outlet 311, and another group of movable air duct inner walls 313 is provided on one side of the side air outlet 311, thereby adjusting the airflow direction and the size of the air outlet from the side air outlet 311.

[0153] It should be noted that, in the figure, P and Q indicate the direction of the inlet air flow and the direction of the outlet air flow, respectively.

[0154] In this embodiment, the two groups of movable air duct wall components 32 cooperate to change the flow area of ​​the ventilation duct and adjust the opening values ​​of the two air outlets 311.

[0155] Specifically, when it is necessary to increase the air flow from the bottom air outlet 311, the movable air duct wall assembly 32 corresponding to the side air outlet 311 is activated to increase the shielding area of ​​the side air outlet 311, reduce the air flow from the side air outlet 311, and direct more air flow toward the bottom air outlet 311.

[0156] At the same time, the movable air duct wall assembly 32 corresponding to the bottom air outlet 311 can be activated to reduce the blocking area of ​​the side air outlet 311, increase the air flow of the side air outlet 311, and direct more airflow toward the bottom air outlet 311.

[0157] When the air flow from the side air outlet 311 needs to be increased, the above process is reversed, and the movable air duct wall assembly 32 provided at the corresponding side air outlet 311 is actuated to reduce the blocking area of ​​the side air outlet 311, increase the air flow from the side air outlet 311, and direct more air flow toward the side air outlet 311.

[0158] At the same time, the movable air duct wall assembly 32 set at the corresponding bottom air outlet 311 can also be activated to increase the shielding area of ​​the side air outlet 311, reduce the air outlet volume of the side air outlet 311, and direct the airflow more toward the direction of the air outlet 311 at the bottom of the side wall.

[0159] In addition, if Figure 13 As shown, the movable air duct wall assembly 32 corresponding to the bottom air outlet 311 can move independently relative to the air guide plate body 231, so that the bottom air outlet 311 can discharge air in a fixed direction horizontally or at a certain angle to the horizontal plane.

[0160] like Figure 13As shown, the movable air duct wall assembly 32 provided corresponding to the bottom air outlet 311 can cooperate with the air guide plate assembly 23 to rotate the air guide plate body 231 to vertical, so that it cooperates with the movable air duct wall assembly 32 provided corresponding to the right air outlet 311 to close the right air outlet 311, and the air guide plate body 231 guides the airflow to vertical, so that the bottom air outlet 311 can discharge air in a fixed direction along the vertical direction.

[0161] Therefore, in summary, this embodiment can achieve the independent air outlet of the bottom air outlet 311, such as Figure 13 、 Figure 15 , and the two air outlets 311 at the bottom and side simultaneously discharge air, such as Figure 14 .

[0162] Example 8

[0163] An embodiment of the present invention discloses an air outlet control method, which uses any one of the air conditioners 1 of embodiments 1 to 5. The air outlet control method comprises: controlling the air outlet state of the air conditioner 1 through the air guide plate assembly 23 and the movable air duct wall assembly 32 to achieve different air outlet modes. Specifically, the method comprises the following steps:

[0164] Step S1: Select the air outlet mode, which includes the closed air outlet mode, the one-way air outlet mode, and the two-way air outlet mode. Among them, the one-way air outlet mode also includes the fixed-angle air outlet mode, the sweeping air mode, and the circular air outlet mode. The two-way air outlet mode also includes the fixed-angle and circular air outlet mode, the sweeping air and circular air outlet mode.

[0165] Step S2: When the selected air outlet mode is the closed air outlet mode, step S3 is executed;

[0166] If the selected air outlet mode is the one-way air outlet mode, execute step S4;

[0167] If the selected air outlet mode is the bidirectional air outlet mode, step S5 is executed.

[0168] Step S3: closing the air outlet, the movable air duct wall assembly 32 closes the corresponding air outlet 311, and the air guide plate assembly 23 moves to close another corresponding air outlet 311;

[0169] Specifically, see Figure 12 The mobile driving element drives the air guide plate body 231 to move and blocks the air outlet 311, thereby closing the corresponding air outlet 311. The driving device 321 drives the active node 33 to move, so that the telescopic panel 322 is unfolded and the corresponding air outlet 311 is closed, thereby closing all the air outlets 311, so that the air conditioner 1 is in the closed air outlet mode.

[0170] Step S4: When the selected air outlet mode is the fixed angle air outlet mode, execute step 4.1;

[0171] When the selected air outlet mode is sweeping mode, go to step 4.2;

[0172] If the selected air outlet mode is circular air outlet mode, proceed to step 4.3;

[0173] Among them, step S4.1 is: the movable air duct wall component 32 closes the corresponding air outlet 311, the air guide plate component 23 moves and opens another corresponding air outlet 311, and the air guide plate component 23 rotates relative to the fixed air duct wall 31 and maintains a fixed inclination angle with the air outlet 311. Specifically, in this step, the action process of the deformable air duct wall is the same as step S3, that is, the driving device 321 drives the movable node 33 to move, so that the telescopic panel 322 is unfolded to close the corresponding air outlet 311, and the action process of the air guide plate assembly 23 is: the moving driving element drives the air guide plate body 231 to move and open the air outlet 311, that is, as shown in the figure, the moving driving element drives the air guide plate body 231 to move downward, and then the air guide plate assembly 23 rotates under the drive of the rotating driving element and rotates to a suitable angle according to the actual needs of the user, thereby maintaining the fixed direction of the lower air outlet 311 as shown in the figure;

[0174] It should be noted that in the fixed angle air outlet mode, there are two special air outlet situations, one of which is Figure 11 As shown, the lower air outlet 311 discharges air in a vertical direction, which is achieved by: the air guide plate assembly 23 is driven by the rotary drive element to rotate to a vertical position, and the rotating air guide plate body 231 abuts against the active node 33 in the air duct structure 3, forming a baffle that closes the right air outlet 311, thereby closing the right air outlet 311 and achieving vertical downward air discharge from the lower air outlet 311 to meet the user's high-volume vertical air outlet requirements;

[0175] Two of them are Figure 1 As shown, the air outlet 311 on the lower side discharges air along the two sides of the air guide body in the horizontal direction. The implementation process is as follows: under the premise that the air outlet 311 on the side is closed,

[0176] The air guide plate assembly 23 is driven by the mobile driving element to descend, opening the lower air outlet 311, and is driven by the rotating driving element to rotate to the horizontal, thereby closing the right air outlet 311 and allowing air to flow out of the lower air outlet 311. When air is discharged from the lower air outlet 311, the air flow is blown out from both sides of the air guide plate body 231 in the air guide plate assembly 23 due to the horizontal guidance of the air guide plate assembly 23, so as to meet the user's demand for this air outlet method.

[0177] Step S4.2: The movable air duct wall assembly 32 closes the corresponding air outlet 311, and the air deflector assembly 23 moves to open the other corresponding air outlet 311 and rotates and swings relative to the fixed air duct wall 31. Specifically, the process of the movable air duct wall assembly 32 closing the corresponding air outlet 311 is the same as the aforementioned step S4.1 and is not repeated here. The only difference between the operation process of the air deflector assembly 23 and step S4.1 is that the air deflector assembly 23 rotates and swings periodically under the drive of the rotary drive element, thereby realizing that the air conditioner 1 is in the wind sweeping operation mode of the lower air outlet 311;

[0178] Step S4.3: See Figure 10 , the air guide plate assembly 23 moves to close the corresponding air outlet 311, and the movable air duct wall assembly 32 moves and opens the corresponding other air outlet 311. Specifically, the action process of the air guide plate assembly 23 is the same as the process of the air guide plate assembly 23 closing the air outlet 311 in step S3, and in this step, the action process of the movable air duct wall assembly 32 is: the driving device 321 drives the movable node 33 to move, that is, the direction shown in the figure is to drive the movable node 33 to move upward, so that the telescopic panel 322 contracts, thereby opening the corresponding air outlet 311, and the air flow discharged through the air outlet 311 enters the annular air outlet structure 24, and is discharged through the annular flow channel of the annular air outlet structure 24, thereby realizing annular air outlet;

[0179] Step S5: When the selected air outlet mode is the fixed inclination angle and circular air outlet mode, execute step S5.1;

[0180] When the selected air outlet mode is the sweep air outlet mode or the circular air outlet mode, execute step S5.2;

[0181] Step S5.1: See Figure 1 , the movable air duct wall assembly 32 moves and opens the corresponding air outlet 311, and the air guide plate assembly 23 moves and opens another air outlet 311, and rotates relative to the fixed air duct wall 31, and maintains a fixed inclination angle. Specifically, the action process of the movable air duct wall assembly 32 is as follows: the driving device 321 drives the movable node 33 to move, that is, the direction shown in the figure is to drive the movable node 33 to move upward, so that the telescopic panel 322 contracts, thereby opening the corresponding air outlet 311, and the air flow discharged through the air outlet 311 enters In the annular air outlet structure 24, the air is discharged through the annular flow channel of the annular air outlet structure 24.
