Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to a rotary air outlet assembly capable of delivering air throughout the entire airflow area, an air conditioner, and an air conditioning delivery method. Background Technology

[0002] The casing of existing air conditioner indoor units is generally fixed to a wall or other fixed object. The air conditioner casing is a fixed structure, which keeps the air outlet duct fixed as well. In some installation environments, due to the size limitations of the air conditioner indoor unit and the limitations of the installation location, the position of the air outlet needs to be adjusted. Since the air outlet duct of the existing air conditioner indoor unit cannot be adjusted, if the position of the air outlet is to be adjusted, a special installation location needs to be selected, which restricts the installation location and increases the installation difficulty, or additional brackets need to be installed, thus increasing the overall cost of the air conditioner.

[0003] Current air conditioners require users to preset the on / off time via remote control or mobile phone to turn them on and off. They cannot automatically detect whether someone is in the room and turn them on or off, resulting in a low level of intelligence. Furthermore, users often forget to turn off the air conditioner when leaving the room, leading to wasted electricity. When the indoor temperature reaches the set value or the difference between the set value and the preset range, and a comfortable cooling or heating airflow is needed, the airflow volume and mode generally need to be manually adjusted, failing to achieve automatic comfortable airflow. Additionally, the air deflector of current air conditioners is usually rotated at the air outlet of the indoor unit, adjusting the airflow direction by swinging its angle. Due to the limited swing angle, when a small volume of comfortable airflow is needed, the deflector is usually swung to a small angle with the bottom or top of the air outlet. This causes the airflow to be directed towards people or directly towards the ceiling, thus limiting the airflow direction and preventing omnidirectional airflow.

[0004] Furthermore, existing air conditioning deflectors are generally located at the bottom of the indoor unit frame. In heating mode, hot air flows upwards in the room. The air outlet angle is limited by the swing angle of the deflector, the size of the deflector, and the size and angle of the outlet. During the rotation of the deflector, the back side of the deflector cannot be adjusted at a small angle with the air conditioning casing. As a result, most of the hot air flows out from the front of the deflector, and only a small portion flows out from the guide area between the back of the deflector and the casing. Moreover, since the hot air flowing out from the guide area between the back of the deflector and the casing is closer to the ground, the proportion of hot air flowing to the ground in existing technology is relatively small. This results in the temperature of the area close to the ground not being effectively improved, thus limiting the heating range and reducing heating efficiency. Summary of the Invention

[0005] To address the aforementioned technical problems, one objective of this invention is to provide a rotating air outlet assembly capable of delivering air throughout the entire airflow area. By incorporating an external rotating air guide, the length of the air outlet channel is extended, while also increasing the rotational adjustment of the air conditioning outlet channel. This ensures that the final air outlet position of the air conditioner can be adjusted according to the rotation angle of the external rotating air guide to meet the air outlet angle requirements of different installation environments. Furthermore, the external rotating air guide, in conjunction with the internal air guide plate, enables multi-angle adjustment of the air outlet angle of the air conditioner, achieving full-area airflow in comfortable scenarios such as sleep, high-volume airflow in cooling mode, and improved heating efficiency in heating mode.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows:

[0007] A rotary air outlet assembly capable of supplying air throughout the entire surface is installed at the air outlet of the housing of an indoor air conditioning unit. The air outlet is located on the front of the housing. The rotary air outlet assembly includes:

[0008] An external rotating air guide is rotatably installed at the air outlet. The external rotating air guide rotates at the air outlet by reciprocating oscillation, so that the external rotating air guide rotates to the outside or inside of the air outlet. A ventilation opening is formed on the external rotating air guide that communicates with the inner cavity of the housing.

[0009] An inner air guide plate is installed on an outer rotating air guide component. The inner air guide plate can rotate at the vent to adjust the angle between the inner air guide plate and the outer rotating air guide component, as well as the opening angle of the vent; and / or the inner air guide plate can be pushed and moved back and forth at the vent in a direction perpendicular to the vent. When the inner air guide plate moves into the interior of the outer rotating air guide component, it disengages from the vent and forms an annular air outlet gap with the inner wall of the outer rotating air guide component.

[0010] This design extends the length of the air outlet duct by rotating the external air guide, while also increasing the rotational adjustment of the air outlet duct. This allows the length and angle of the air outlet duct to be adjusted according to the installation and usage environment, ensuring that the final air outlet position can be adjusted according to the rotation angle of the external air guide to meet the air outlet angle in different installation environments. At the same time, the external air guide, in conjunction with the internal air guide plate, can achieve multi-angle adjustment of the air outlet angle, enabling full-area air outlet in comfortable scenarios such as sleep, large-volume air outlet in cooling mode, and improved heating efficiency in heating mode.

[0011] Preferably, the outer rotating air guide has an air guide cavity that is connected to the vent. Any cross-sectional dimension of the air guide cavity along the length of the outer rotating air guide is larger than the cross-sectional dimension of the vent.

[0012] Preferably, the external rotating air guide includes a front plate, two oppositely arranged side plates, a bottom plate, and a top plate. The front plate is located on the side of the external rotating air guide near the air outlet. The two side plates are respectively located on both sides of the front plate. The bottom plate and the top plate are located above and below the front plate, respectively. The vent is located on the front plate. The outer ring of the front plate is adapted to the air outlet so that the front plate, together with the inner air guide plate located at the vent, can seal the air outlet. The front plate, the two oppositely arranged side plates, the bottom plate, and the top plate together form the air guide cavity.

[0013] With this configuration, when the outer rotating air guide is in its initial position, the front plate and the air outlet are on the same plane, and the air outlet is sealed together by the front plate and the inner air guide plate. At this time, the side plate, bottom plate, top plate of the outer rotating air guide and the air guide cavity are all located in the inner cavity of the housing. When the outer rotating air guide is rotated outward from the air outlet, the side plate and top plate rotate out of the inner cavity of the housing, so that the air guide cavity also rotates out of the inner cavity of the housing. At this time, the air guide cavity extends the length of the air outlet channel of the housing, and the rotation of the air guide cavity at a certain angle can adjust the final air outlet angle of the entire air outlet channel, thereby meeting the adjustment of the air outlet angle of the air outlet channel according to the needs.

[0014] Preferably, the top plate is an arc-shaped plate, which is bent upward from the inner cavity of the shell towards the air outlet, so that the side of the top plate near the air outlet is higher than the side of the top plate away from the air outlet.

[0015] This design allows the top plate to be an upwardly curved arc plate. When the outer rotating air guide rotates outward towards the air outlet, the top plate will not contact the top of the air outlet, thus hindering the rotation of the outer rotating air guide.

[0016] Preferably, one side of the top plate is connected to the top of the front plate, that is, the installation position of the top plate should be higher than the top of the vent. This allows the air guide cavity of the external rotating air guide to have sufficient air guide height and air guide space. As a result, when the external rotating air guide rotates to the outside of the air outlet, the air guide cavity has enough space to extend the air outlet channel of the housing.

[0017] Preferably, the width of the top of the side plate is greater than the width of the bottom of the side plate. This is because when the external rotating air guide rotates outward from the air outlet, the part of the side plate that rotates outward from the air outlet is a fan-shaped surface. Therefore, even if the width of the top of the side plate is greater than the width of the bottom, it can still ensure normal air outlet of the air guide cavity. At the same time, it can save the volume and weight of the side plate, thereby reducing the overall weight of the external rotating air guide.

[0018] Preferably, the outer rotating air guide is installed at the bottom of the inner cavity of the housing via a rotating drive mechanism, which includes a rotating drive motor and a rotating shaft. The rotating drive motor is installed at the bottom of the inner cavity of the housing near the air outlet. Specifically, the rotating drive motor can be located at the bottom of the inner cavity side wall or on the inner cavity bottom wall of the housing. One end of the rotating shaft is connected to the rotating drive motor, and the other end of the rotating shaft is connected to one side plate of the outer rotating air guide. The other side plate of the outer rotating air guide is rotatably connected to the inner cavity side wall of the housing via a rotating shaft, so that the rotating drive motor drives the outer rotating air guide to rotate at the air outlet.

[0019] Preferably, the inner cavity of the outer rotating air guide is provided with a rotating mechanism for driving the inner air guide plate to rotate. The rotating mechanism includes a rotating motor, a drive shaft and a connecting rod. The rotating motor is installed on one side wall of the outer rotating air guide. One side of the inner air guide plate is connected to the rotating motor through the drive shaft. The other side of the inner air guide plate is rotatably connected to the other side wall of the outer rotating air guide through the connecting rod.

[0020] This configuration allows the inner air guide plate to rotate via a rotating motor, thereby adjusting the opening angle of the vents on the outer rotating air guide and ultimately adjusting the airflow volume and direction of the airflow discharged from the outer rotating air guide.

[0021] Preferably, the rotating motor is installed inside the side plate of the outer rotating air guide, one end of the drive shaft is fixedly connected to the middle position of one side width of the inner air guide plate, and one end of the connecting rod is fixedly connected to the middle position of the other side width of the inner air guide plate. This arrangement allows the inner air guide plate to rotate around its center line when the rotating motor drives the inner air guide plate to rotate, thereby causing the airflow to flow out from above or below the inner air guide plate.

[0022] Preferably, the inner air guide plate is a hollow plate with a slot extending along its length and running through the entire inner air guide plate. This design reduces the overall weight of the inner air guide plate. Furthermore, both the front and rear sides of the inner air guide plate can be curved, allowing for better airflow on both the front and rear sides of the inner air guide plate when it rotates towards the inside or outside of the vent, thus improving the airflow guiding effect.

[0023] Preferably, both sides of the inner air guide plate are provided with connecting plates extending inward to the vent. The connecting plates are perpendicular to the width of the inner air guide plate. The connecting plates are provided with mounting holes for assembly with the drive shaft or connecting rod. The connecting plates allow for a certain gap between the drive motor and the vent, so that the inner air guide plate can better fit with the vent and thus better seal the vent. There is no excessive gap between the inner air guide plate and the vent.

[0024] Preferably, the inner cavity of the outer rotating air guide is further provided with a pushing device for driving the inner air guide plate to reciprocate at the vent in a direction perpendicular to the vent.

[0025] Preferably, the pushing device includes a translational pushing motor, a driving gear, and a driven rack. The translational pushing motor is mounted on one side wall of the outer rotating air guide. The driving gear is connected to the output shaft of the translational pushing motor. The driven rack is mounted on the outer wall of the rotating motor. The rack surface of the driven rack meshes with the driving gear. The translational pushing motor drives the driving gear to rotate. The driving gear drives the driven rack to make outward or inward movements along the air outlet direction perpendicular to the vent, so as to drive the rotating motor and the inner air guide plate to move into the air guide cavity of the outer rotating air guide.

[0026] Preferably, a motor mounting base is provided on the side of the driven rack away from the rack surface. The motor mounting base is connected to the mounting plate inside the outer rotating air guide through a slide rail assembly. The mounting plate is arranged parallel to the side plate of the outer rotating air guide. A mounting cavity for mounting the motor mounting base and the pushing device is formed between the mounting plate and the adjacent side plate. The mounting plate is also provided with a slide groove for the rotating shaft to pass through. The slide rail assembly includes a slider provided on one side of the motor mounting base and a slide rail provided on the mounting plate. The slide rail assembly can ensure that the pushing motor maintains stable operation when pushing the rotating motor and the inner air guide plate to move in the air guide cavity of the outer rotating air guide. One side of the motor mounting base is used to fix the rotating motor. The connecting rod is slidably connected to the sliding groove on the side plate of the outer rotating air guide, so that the connecting rod can move together with the inner air guide plate without affecting the rotation of the subsequent connecting rod.

[0027] This design uses a pushing device to move the inner air guide plate within the air guide cavity of the outer rotating air guide. When the inner air guide plate moves into the outer rotating air guide, it disengages from the vent and forms an annular air outlet gap with the inner wall of the outer rotating air guide. The airflow generated by the indoor unit of the air conditioner flows out from the vent of the outer rotating air guide after passing through this annular air outlet gap, forming an annular full-area air outlet. This achieves annular full-area air outlet in full-area wind mode and low-volume air outlet in sleep mode. This annular full-area air outlet can both expand the air outlet direction, allowing airflow to be discharged from all directions around the vent, and reduce air volume, thus reducing the power consumption of the air conditioner.

[0028] A second objective of this invention is to provide an air conditioner, including an indoor unit, wherein the indoor unit is equipped with a rotating air outlet assembly capable of delivering air throughout the entire airflow area as described above.

[0029] The third objective of this invention is to provide an air conditioning air supply method, which employs the air conditioner described above and includes the following steps:

[0030] S1. The radar emits radar waves to scan the room to determine whether there are users in the room. If no one is detected in the room, the controller controls the air conditioner to be in standby mode. If someone is detected in the room, the controller controls the air conditioner to cool or heat and blow air according to the indoor temperature information detected by the temperature detector. The initial time when the radar waves detect someone in the room is recorded as T0.

[0031] S2. The controller sets the temperature parameters based on the weather information of the day and the indoor temperature information detected in step S1. When the controller controls the air conditioner to start cooling or heating from time T0, the air control air conditioner starts the normal air supply mode. When the temperature detector detects that the difference between the indoor temperature and the set temperature reaches the set difference, the controller controls the air conditioner to activate the full-area wind mode. In the full-area wind mode, the air conditioner's inner air guide plate rotates outward and moves inside the air guide component and separates from the vent, so that an annular air outlet gap is formed between the inner air guide plate and the inner wall of the outer rotating air guide component.

[0032] Preferably, when the air conditioner is in standby mode, the external rotating air guide is retracted into the inner cavity of the indoor unit. When the front panel of the external rotating air guide and the inner air guide plate at the vent are both vertical and the vent is closed, the air outlet of the indoor unit is also closed, thus putting the air conditioner in standby mode. Normal air supply modes include normal cooling air supply mode and normal heating air supply mode. In normal cooling air supply mode, the external rotating air guide can rotate a certain angle outwards from the air outlet according to the environment or user instructions, thereby changing the air outlet angle at the end of the air outlet channel. Alternatively, the external rotating air guide can remain stationary within the inner cavity of the casing. By rotating the inner air guide plate to a position perpendicular to the vent, the obstruction of the vent by the inner air guide plate is minimized, thus maximizing the airflow and achieving the strongest cooling effect. Therefore, in normal cooling air supply mode, the inner air guide plate needs to be rotated to a position perpendicular to the vent to achieve rapid and normal cooling airflow. In normal heating and air supply mode, the external rotating air guide is driven by a rotary drive mechanism to rotate at the air outlet, thereby adjusting the overall air outlet angle of the air outlet duct of the indoor unit of the air conditioner. This causes the air outlet of the external rotating air guide to bend towards the ground. At the same time, the internal air guide plate is driven by the rotary mechanism to rotate at the air outlet, causing the lower half of the internal air guide plate to rotate outward from the air outlet and the upper half of the internal air guide plate to rotate inward from the air outlet. This ensures that the airflow from the air outlet is guided obliquely downward to an area closer to the ground, thereby improving the heating effect of the air conditioner. When the controller activates the full-area airflow mode, the inner air guide plate remains parallel to the vent and moves inward in a direction perpendicular to the vent within the air guide cavity of the outer rotating air guide. As the inner air guide plate moves into the outer rotating air guide, it disengages from the vent and forms an annular air outlet gap with the inner wall of the outer rotating air guide. The back of the inner air guide plate can block most of the air conditioning air discharged from the indoor unit's fan wheel, thus ensuring that the air conditioning air is discharged only from the annular air outlet gap, thereby forming full-area airflow, improving the comfort of the airflow, and ensuring that the difference between the indoor temperature and the set temperature is maintained within the set difference.

[0033] Preferably, during the operation of the air conditioner, when the radar wave scan detects that no one has been in the room for a certain period of time △T1, the controller controls the air conditioner to reduce its frequency, thereby improving the energy-saving effect of the air conditioner and preventing the indoor temperature from dropping or rising rapidly when the user turns off the air conditioner during a short period of time away from home. This frequency reduction step enables the air conditioner to operate under low-frequency conditions during the short period of time when the user leaves.

[0034] Preferably, when the radar wave scan detects that no one has been in the room for a certain period of time △T2, the controller controls the air conditioner to turn off, where △T2 > △T1.

[0035] Preferably, in step S1, the radar scans the room by emitting radar waves once per minute or twice per minute to determine whether there are people in the room.

[0036] Compared with the prior art, the present invention has achieved beneficial technical effects:

[0037] 1. The rotating air outlet assembly of the present invention, which can deliver air throughout the entire area, increases the rotational adjustment of the air outlet at the end of the air outlet channel by setting an external rotating air guide, so that the air outlet channel of the air conditioner can be extended and the angle adjusted according to the installation and use environment. This ensures that the position of the air outlet can meet the adjustment and use in complex installation environments. At the same time, the external rotating air guide, together with the internal air guide plate, can realize multiple degrees of adjustment of the air outlet angle of the air conditioner, so as to achieve full-area air delivery in comfortable scenarios such as sleep, large air volume in cooling mode, and improved heating efficiency in heating mode.

[0038] 2. The rotating air outlet assembly of this invention, capable of providing omnidirectional airflow, uses a pushing device to move the inner air guide plate within the air guide cavity of the outer rotating air guide component. When the inner air guide plate moves inward into the outer rotating air guide component, it disengages from the vent and forms an annular air outlet gap with the inner wall of the outer rotating air guide component. The airflow generated by the indoor unit of the air conditioner flows out from the vent of the outer rotating air guide component after passing through this annular air outlet gap, forming an annular omnidirectional airflow. This achieves annular omnidirectional airflow in omnidirectional wind mode and low-volume airflow in sleep mode. This annular omnidirectional airflow not only expands the airflow direction, allowing airflow to be discharged from all directions around the vent, but also reduces the airflow volume and lowers the power consumption of the air conditioner.

[0039] 3. The air conditioning air supply method of the present invention can automatically identify whether there are people in the room by radar waves to start and stop the air conditioner, which has a high degree of intelligence. When the user leaves the room for a certain period of time, the air conditioner will first reduce the frequency to reduce the power consumption of the air conditioner. When the user leaves for a longer period of time, the air conditioner will be turned off to avoid the user forgetting to turn off the air conditioner. When the air conditioner controller detects that the difference between the indoor temperature and the set temperature reaches the set difference, the controller controls the air conditioner to activate the full-area air mode, so that the air conditioner can automatically output comfortable cooling or heating air throughout the room, while ensuring that the difference between the indoor temperature and the set temperature is maintained within the set difference.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments. However, the scope of protection of this invention is not limited to the specific embodiments described below.

[0051] Example 1

[0052] refer to Figure 1-4As shown, this embodiment discloses a rotary air outlet assembly capable of supplying air throughout the entire area. The rotary air outlet device is installed at the air outlet 11 of the housing 1 of the air conditioner indoor unit. The air outlet 11 is located on the front of the housing 1. The rotary air outlet device includes an outer rotary air guide 2 and an inner air guide plate 3. The outer rotary air guide 2 is rotatably installed at the air outlet 11. The outer rotary air guide 2 rotates at the air outlet 11 by reciprocating oscillation, so that the outer rotary air guide 2 rotates to the outside or inside of the air outlet 11. The outer rotary air guide 2 forms a surface that is flush with the housing. The inner cavity of 1 is connected to the ventilation opening 211; the inner air guide plate 3 is installed on the outer rotating air guide 2, and the inner air guide plate 3 can rotate at the ventilation opening 211 to adjust the angle between the inner air guide plate 3 and the outer rotating air guide 2 and the opening angle of the ventilation opening 211; and / or the inner air guide plate 3 can be pushed and translated back and forth at the ventilation opening 211 in a direction perpendicular to the ventilation opening 211. When the inner air guide plate 3 moves into the interior of the outer rotating air guide 2, it disengages from the ventilation opening 211 and forms an annular air outlet gap with the inner wall of the outer rotating air guide 2.

[0053] The rotation of the outer rotating air guide 2 extends the length of the air outlet channel and increases the rotation adjustment of the air outlet channel, so that the length and angle of the air outlet channel can be adjusted according to the installation and use environment. This ensures that the final air outlet position of the air conditioner can be adjusted according to the rotation angle of the outer rotating air guide 2 to meet the air outlet angle in different installation environments. At the same time, the outer rotating air guide 2, together with the inner air guide plate 3, can realize multi-angle adjustment of the air outlet angle of the air conditioner outlet 11, so as to achieve full-area air outlet in comfortable scenarios such as sleep, large air volume air outlet in cooling mode, and improved heating efficiency in heating mode.

[0054] refer to Figure 4 As shown, the outer rotating air guide 2 has an air guide cavity that communicates with the vent 211. The cross-sectional dimension of the air guide cavity along the length of the outer rotating air guide 2 is larger than the cross-sectional dimension of the vent 211. The outer rotating air guide 2 includes a front plate 21, two opposing side plates 22, a bottom plate 24, and a top plate 23. The front plate 21 is located on the side of the outer rotating air guide 2 closest to the air outlet 11. The two side plates 22 are respectively located on both sides of the front plate 21. The bottom plate 24 and the top plate 23 are located above and below the front plate 21, respectively. The vent 211 is located on the front plate 21. The outer ring of the front plate 21 is adapted to the air outlet 11 so that the front plate 21, together with the inner air guide plate 3 placed at the vent 211, seals the air outlet 11. The front plate 21, the two opposing side plates 22, the bottom plate 24, and the top plate 23 together form the air guide cavity.

[0055] When the outer rotating air guide 2 is in its initial position, the front plate 21 and the air outlet 11 are on the same plane. The air outlet 11 is closed by the front plate 21 and the inner air guide plate 3. At this time, the side plate 22, bottom plate 24, top plate 23 and air guide cavity of the outer rotating air guide 2 are all located in the inner cavity of the housing 1. When the outer rotating air guide 2 is rotated to the outside of the air outlet 11, the side plate 22 and top plate 23 rotate out of the inner cavity of the housing 1, so that the air guide cavity also rotates out of the inner cavity of the housing 1. At this time, the air guide cavity extends the length of the air outlet channel of the housing 1. The air guide cavity rotates at a certain angle, which can adjust the final air outlet angle of the overall air outlet channel, thereby meeting the adjustment of the air outlet angle of the air outlet channel according to the needs.

[0056] The top plate 23 is an arc-shaped plate, which extends upward from the inner cavity of the housing 1 toward the air outlet 11, such that the side of the top plate 23 closer to the air outlet 11 is higher than the side of the top plate 23 farther away from the air outlet 11. This arrangement makes the top plate 23 an upwardly curved arc-shaped plate, so that when the outer rotating air guide 2 rotates outward toward the air outlet 11, the top plate 23 will not contact the top of the air outlet 11, thus hindering the rotation of the outer rotating air guide 2.

[0057] One side of the top plate 23 is connected to the top of the front plate 21, that is, the installation position of the top plate 23 is higher than the top of the vent 211. This allows the air guide cavity of the outer rotating air guide 2 to have sufficient air guide height and air guide space. As a result, when the outer rotating air guide 2 rotates to the outside of the air outlet 11, the air guide cavity has enough space to extend the air outlet channel of the housing 1.

[0058] The width of the top of the side plate 22 is greater than the width of the bottom of the side plate 22. This is because when the outer rotating air guide 2 rotates outward from the air outlet 11, the part of the side plate 22 that rotates outward from the air outlet 11 is a fan-shaped surface. Therefore, even if the width of the top of the side plate 22 is greater than the width of the bottom, it can still ensure normal air outlet of the air guide cavity. At the same time, it can save the volume and weight of the side plate 22, thereby reducing the overall weight of the outer rotating air guide 2.

[0059] refer to Figure 4 As shown, the outer rotating air guide 2 is installed at the bottom of the inner cavity of the housing 1 through a rotating drive mechanism 4. The rotating drive mechanism 4 includes a rotating drive motor 41 and a rotating shaft. The rotating drive motor 41 is installed in the inner cavity of the housing 1 near the bottom of the air outlet 11. Specifically, the rotating drive motor 41 can be set at the bottom of the inner cavity side wall of the housing 1 or on the inner cavity bottom wall of the housing 1. One end of the rotating shaft is connected to the rotating drive motor 41, and the other end of the rotating shaft is connected to one side plate 22 of the outer rotating air guide 2. The other side plate 22 of the outer rotating air guide 2 is rotatably connected to the inner cavity side wall of the housing 1 through a rotating shaft, so that the rotating drive motor 41 drives the outer rotating air guide 2 to rotate at the air outlet 11.

[0060] refer to Figure 7 and 8 As shown, the outer rotating air guide 2 has a rotating mechanism 5 inside its air guide cavity for driving the inner air guide plate 3 to rotate. The rotating mechanism 5 includes a rotating motor 51, a drive shaft 52, and a connecting rod. The rotating motor 51 is mounted on one side wall of the outer rotating air guide 2. One side of the inner air guide plate 3 is connected to the rotating motor 51 via the drive shaft 52, and the other side of the inner air guide plate 3 is rotatably connected to the other side wall of the outer rotating air guide 2 via the connecting rod. The rotating motor 51 can drive the inner air guide plate 3 to rotate, thereby adjusting the opening angle of the vent 211 on the outer rotating air guide 2, and thus adjusting the airflow volume and direction of the airflow finally discharged from the outer rotating air guide 2.

[0061] The rotating motor 51 is installed inside the side plate 22 of the outer rotating air guide 2. One end of the drive shaft 52 is fixedly connected to the middle position of one side width of the inner air guide plate 3, and one end of the connecting rod is fixedly connected to the middle position of the other side width of the inner air guide plate 3. This arrangement allows the inner air guide plate 3 to rotate around its center line when the rotating motor 51 drives the inner air guide plate 3 to rotate, thereby causing the airflow to flow out from above or below the inner air guide plate 3.

[0062] Both sides of the inner air guide plate 3 are provided with connecting plates 31 extending into the air vent 211. The connecting plates 31 are perpendicular to the width of the inner air guide plate 3. The connecting plates 31 are provided with mounting holes for assembly with the drive shaft 52 or connecting rod. The connecting plates 31 allow for a certain gap between the drive motor and the air vent 211, so that the inner air guide plate 3 can better cooperate with the air vent 211 and better seal the air vent 211. There is an excessive gap between the inner air guide plate 3 and the air vent 211.

[0063] The outer rotating air guide 2 is also equipped with a pushing device in its inner cavity for driving the inner air guide plate 3 to reciprocate in a direction perpendicular to the vent 211 at the vent 211. The pushing device includes a translational pushing motor, a driving gear, and a driven rack. The translational pushing motor is mounted on one side wall of the outer rotating air guide 2. The driving gear is connected to the output shaft of the translational pushing motor. The driven rack is mounted on the outer wall of the rotating motor 51. The rack surface of the driven rack meshes with the driving gear. The translational pushing motor drives the driving gear to rotate. The driving gear drives the driven rack to push outward or inward in a direction perpendicular to the air outlet of the vent 211, thereby moving the rotating motor 51 and the inner air guide plate 3 into the inner cavity of the outer rotating air guide 2.

[0064] Example 2

[0065] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is as follows:

[0066] The inner air guide plate 3 is a hollow plate. The inner air guide plate 3 is provided with a slot 32 that extends along the length of the inner air guide plate 3 and runs through the entire inner air guide plate 3. This design can reduce the overall weight of the inner air guide plate 3. The front and rear sides of the inner air guide plate 3 can be designed as arc surfaces. Therefore, when the inner air guide plate 3 rotates to the inside or outside of the ventilation opening 211, the airflow can be better flowed on both the front and rear sides of the inner air guide plate 3, thus improving the air guiding effect.

[0067] Example 3

[0068] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is as follows:

[0069] refer to Figure 5 and 6 As shown, a motor mounting base 6 is provided on the side of the driven rack away from the rack surface. The motor mounting base 6 is connected to the mounting plate 25 inside the outer rotating air guide 2 via a slide rail assembly. The mounting plate 25 is arranged parallel to the side plate 22 of the outer rotating air guide 2. A mounting cavity for mounting the motor mounting base 6 and the pushing device is formed between the mounting plate 25 and the adjacent side plate 22. The mounting plate 25 is also provided with a slide groove 26 for the rotating shaft to pass through. The slide rail assembly includes a slider provided on one side of the motor mounting base 6 and a slide rail provided on the mounting plate 25. The slide rail assembly can ensure that the pushing motor maintains stable operation when pushing the rotating motor 51 and the inner air guide plate 3 to move in the air guide cavity of the outer rotating air guide 2. The motor mounting base 6 is provided with a mounting groove for fixing the rotating motor 51. The connecting rod is slidably connected to the sliding groove on the side plate 22 of the outer rotating air guide 2. This allows the connecting rod to move together with the inner air guide plate 3 without affecting the rotation of the subsequent connecting rod.

[0070] The inner air guide plate 3 moves within the air guide cavity of the outer rotating air guide 2 by a pushing device. When the inner air guide plate 3 moves into the outer rotating air guide 2, it disengages from the vent 211 and forms an annular air outlet gap with the inner wall of the outer rotating air guide 2. The airflow generated by the indoor unit of the air conditioner flows out from the vent 211 of the outer rotating air guide 2 after passing through this annular air outlet gap, forming an annular full-area air outlet. This achieves small air volume full-area air outlet in unattended mode and small air volume air outlet in comfort modes such as sleep mode. This annular full-area air outlet can both expand the air outlet direction, allowing airflow to be discharged from all directions around the vent 211, and reduce the air volume and reduce the power consumption of the air conditioner.

[0071] Example 4

[0072] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is as follows:

[0073] A motor mounting base 6 is provided on the side of the driven rack away from the rack surface. The motor mounting base 6 is connected to the inner side of the side plate 22 of the outer rotating air guide 2 through a slide rail assembly. The slide rail assembly includes a slider provided on one side of the motor mounting base 6 and a slide rail provided on the side plate 22.

[0074] Example 5

[0075] Based on embodiments one to four, this embodiment discloses an air conditioner, including an outdoor unit and an indoor unit. The indoor unit is equipped with a rotating air outlet assembly capable of supplying air throughout the entire area, as described in embodiments one to four, at its air outlet 11.

[0076] Example 6

[0077] Based on Embodiment 5, this embodiment discloses an air conditioning air supply method. The air conditioning air supply method of this embodiment uses the air conditioner in Embodiment 5, and the air conditioning air supply method includes the following steps:

[0078] S1. The radar emits radar waves to scan the room to determine whether there are users in the room. If no one is detected in the room, the controller controls the air conditioner to be in standby mode. If someone is detected in the room, the controller controls the air conditioner to cool or heat and blow air according to the indoor temperature information detected by the temperature detector. The initial time when the radar waves detect someone in the room is recorded as T0.

[0079] S2. The controller sets the temperature parameters based on the weather information of the day and the indoor temperature information detected in step S1. When the controller controls the air conditioner to start cooling or heating from time T0, the air control air conditioner starts the normal air supply mode. When the temperature detector detects that the difference between the indoor temperature and the set temperature reaches the set difference, the controller controls the air conditioner to activate the full-area wind mode. In the full-area wind mode, the inner air guide plate 3 of the air conditioner rotates outward and moves inside the air guide 2 and separates from the vent 211, so that an annular air outlet gap is formed between the inner air guide plate 3 and the inner wall of the outer rotating air guide 2.

[0080] The radar can emit millimeter radar waves. It can be installed on the indoor unit of an air conditioner or on other electronic devices in the room that can exchange data with the air conditioner's controller. The air conditioner's controller receives the radar scan results from other electronic devices to determine whether there is anyone in the room and how long the room will remain empty.

[0081] When the air conditioner is in standby mode, the external rotating air guide 2 is retracted into the inner cavity of the indoor unit of the air conditioner. When the front plate 21 of the external rotating air guide 2 and the inner air guide plate 3 at the vent 211 are both in a vertical state and the vent 211 is closed, the air outlet 11 of the indoor unit of the air conditioner will also be closed, thus putting the air conditioner in standby mode.

[0082] Normal air supply mode includes normal cooling air supply mode and normal heating air supply mode. In normal cooling air supply mode, the outer rotating air guide 2 can rotate a certain angle to the outside of the air outlet 11 according to the site environment or user operation instructions, thereby changing the air outlet angle at the end of the air outlet channel. Alternatively, the outer rotating air guide 2 can remain stationary in the inner cavity of the housing 1. By rotating the inner air guide plate 3 to a position perpendicular to the vent 211, the obstruction of the inner air guide plate 3 to the vent 211 is minimized, thereby maximizing the air supply of the air conditioner and achieving the strongest cooling effect. Therefore, in normal cooling air supply mode, the inner air guide plate 3 needs to be rotated to a position perpendicular to the vent 211 to achieve rapid and normal cooling air supply.

[0083] In normal heating and air supply mode, the external rotating air guide 2 is driven to rotate at the air outlet 11 by the rotating drive mechanism 4, thereby adjusting the overall air outlet angle of the air outlet duct of the indoor unit of the air conditioner. This causes the vent 211 of the external rotating air guide 2 to bend towards the ground. At the same time, the internal air guide plate 3 is driven to rotate at the vent 211 by the rotating mechanism 5, causing the lower half of the internal air guide plate 3 to rotate outward from the vent 211 and the upper half of the internal air guide plate 3 to rotate inward from the vent 211. This ensures that the airflow from the vent 211 is guided obliquely downward to an area closer to the ground, thereby improving the heating effect of the air conditioner.

[0084] When the controller activates the full-area airflow mode, the inner air guide plate 3 remains parallel to the vent 211 and moves inward in the air guide cavity of the outer rotating air guide 2 in a direction perpendicular to the vent 211. When the inner air guide plate 3 moves into the inner part of the outer rotating air guide 2, it disengages from the vent 211 and forms an annular air outlet gap with the inner wall of the outer rotating air guide 2. The back of the inner air guide plate 3 can block most of the air conditioning air discharged from the air conditioner indoor unit fan wheel, so that the air conditioning air is discharged only from the annular air outlet gap, thus forming full-area airflow, improving the comfort of the airflow and ensuring that the difference between the indoor temperature and the set temperature can be maintained within the set difference.

[0085] During the operation of the air conditioner, when the radar wave scan detects that no one has been in the room for a certain period of time △T1, the controller controls the air conditioner to reduce its frequency, thereby improving the energy-saving effect of the air conditioner. It can also prevent the indoor temperature from dropping or rising rapidly when the user turns off the air conditioner for a short period of time. This frequency reduction step can enable the air conditioner to operate under low frequency conditions during the short period of time when the user leaves.

[0086] When the radar wave scan detects that no one has been in the room for a certain period of time △T2, the controller will shut down the air conditioner, where △T2 > △T1.

[0087] In step S1, the radar scans the room by emitting radar waves once or twice per minute to determine whether there are people in the room.

[0088] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the invention.
