[0046] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0047] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0048] like Figure 1 As shown, this embodiment of the present disclosure provides an air outlet device 100, including a panel 1 and a turntable 2. The panel 1 has an installation port, and the turntable 2 is rotatably disposed at the installation port. The turntable 2 has an air outlet 21. Preferably, the installation port is a circular installation port, and the turntable 2 cooperates with the circular installation port, allowing the turntable 2 to rotate within it.

[0049] like Figure 2 and Figure 3As shown, to drive the turntable 2 to rotate, a first drive mechanism 3 is fixed on the panel 1. The first drive mechanism 3 is used to drive the turntable 2 to rotate relative to the panel 1, so as to adjust the air outlet direction by rotating the turntable 2. Specifically, a rack 6 is fixed on the periphery of the turntable 2. The first drive mechanism 3 includes a first stepper motor 31 and a gear 32. The gear 32 meshes with the rack 6. The first stepper motor 31 is connected to the gear 32 and is used to drive the gear 32 to rotate, so as to drive the rack 6 and the turntable 2 to rotate, thereby adjusting the air outlet direction by rotating the turntable 2. Preferably, in this embodiment, the turntable 2 can rotate 180 degrees.

[0050] Furthermore, to prevent the gear 32 from shifting along its own axis during rotation, a gear cover 33 is provided between the first stepper motor 31 and the gear 32 to axially limit the gear 32 and ensure the stability of the gear 32's engagement with the rack 6.

[0051] like Figure 2 and Figure 3 As shown, the air outlet device 100 of this embodiment further includes an air guide assembly 4. The air guide assembly 4 includes an air guide plate 42 and a second drive mechanism. The air guide plate 42 is disposed at the air outlet 21. The second drive mechanism is connected to the air guide plate 42 and is used to drive the air guide plate 42 to swing relative to the turntable 2, so as to guide the air passing through the air outlet 21 using the air guide plate 42, thereby adjusting the air outlet direction.

[0052] Specifically, the air guide plate 42 has connecting shaft holes at both ends along its length. The second driving mechanism includes a second stepper motor 41, which is fixed on the turntable 2. The motor shaft of the second stepper motor 41 is fixedly connected to the connecting shaft holes to drive the air guide plate 42 to swing. This method of directly driving the air guide plate 42 to swing using the second stepper motor 41 simplifies the structure. Preferably, in this embodiment, the air guide plate 42 can be positioned relative to... Figure 1 and Figure 2 The initial position shown is rotated 90 degrees clockwise or counterclockwise respectively.

[0053] In a specific embodiment, the turntable 2 can rotate 180 degrees, specifically, it can rotate 90 degrees in each of the two directions from the initial position; the air guide plate 42 can rotate 180 degrees, specifically, it can rotate 90 degrees in each of the two directions from the initial position. This setting not only prevents the wire from twisting, but also achieves the effect of 360-degree all-round air supply.

[0054] like Figures 1 to 3 As shown, the air outlet device 100 of this embodiment further includes a human information sensor 8, which is disposed on the panel 1 and is used to detect user position information. Based on the user position information, the rotation angle of the turntable 2 and the swing angle of the air guide plate 42 can be adjusted to meet the user's requirements for different air delivery angles.

[0055] The air outlet device 100 provided in the above embodiments of this disclosure drives the turntable 2 to rotate relative to the panel 1 through the first drive mechanism 3, and drives the air guide plate 42 to swing relative to the turntable 2 through the second drive mechanism. The rotation of the turntable 2 and the swing of the air guide plate 42 expand the selection range of the air supply direction. The human body information sensor 8 detects the user's position information, so the rotation angle of the turntable 2 and the swing angle of the air guide plate 42 can be automatically adjusted according to the user's position information to achieve the purpose of adjusting the air supply direction, thereby meeting the user's requirements for the air supply angle and improving the user's experience.

[0056] In some embodiments, the air outlet device 100 provided in this disclosure further includes an air dispersion component, which is fixed on the turntable 2 and is used to guide the air from the middle of the air outlet 21 along the length direction to both ends of the air outlet 21, thereby making the air outlet more uniform.

[0057] In one specific embodiment, such as Figure 2 and Figure 3 As shown, the air dispersing component includes two air dispersing vanes 7, which are respectively disposed on both sides of the air outlet 21. The middle of the air dispersing vane 7 is raised, and the height of the air dispersing vane 7 gradually decreases from the middle to both ends along the circumferential direction of the turntable 2. Along the radial direction of the turntable 2, the height of the air dispersing vane 7 gradually decreases from the side away from the air outlet 21 to the side closer to the air outlet 21, so that the air dispersing vane 7 can guide the air from the middle of the air outlet 21 along the length direction to both ends of the air outlet 21.

[0058] In a specific embodiment, the turntable 2 may include a disc body and a surrounding wall connected to the disc body. An air outlet 21 is formed on the disc body, and a diffuser 7 is disposed on the side surface of the disc body facing the surrounding wall. Specifically, the diffuser 7 may include a diffuser body and supporting ribs connected to the lower surface of the diffuser body. The diffuser body may be arc-shaped and supported on the disc body of the turntable 2 by the supporting ribs. The side of the diffuser body away from the air outlet 21 is adapted to the shape of the surrounding wall. Further, spaced-apart limiting ribs may be provided on the side surface of the disc body facing the surrounding wall to limit the diffuser 7 between two limiting ribs.

[0059] Specifically, the main unit 100 of the ceiling electrical appliance 1000 is usually provided with a main unit air outlet 201, which is usually rectangular in shape. The air outlet 21 on the turntable 2 of the air outlet device 100 provided in this embodiment (to distinguish it from the main unit air outlet 201, the air outlet 21 on the turntable 2 can be called the turntable air outlet) is also usually set as rectangular. In this way, when the air outlet direction is adjusted by rotating the turntable 2, the length direction of the main unit air outlet 201 and the length direction of the turntable air outlet 21 will form a certain angle or even be perpendicular. This will make it difficult for the air blown out of the main unit air outlet 201 to reach both ends of the turntable air outlet 21 along the length direction, resulting in the problem that the air is concentrated and blown out from the middle part of the turntable air outlet 21. To this end, the air outlet device 100 of this embodiment provides air diffusers 7 on both sides of the air outlet 21, which can guide the air from the middle of the turntable air outlet 21 along the length direction to both ends of the turntable air outlet 21, thereby making the air outlet more uniform.

[0060] In some embodiments, such as Figures 1 to 3 As shown, the air outlet device 100 of this embodiment further includes a mounting frame 5, which is fixed on the panel 1 and used to connect with the keel 300 integrated on the ceiling to install the air outlet device 100 on the ceiling.

[0061] like Figure 4 and Figure 5 As shown in the illustration, this disclosure also provides a ceiling-mounted electrical appliance 1000, including a main unit 100 and an air outlet device 100 as described in any of the above embodiments. The air outlet device 100 is connected to the air outlet 201 of the main unit to discharge the air generated by the main unit 100. A controller 202 is provided on the main unit 100, and the controller 202 is electrically connected to the first drive mechanism (specifically, the first stepper motor 31), the second drive mechanism (specifically, the second stepper motor 41), and the human body information sensor 8 of the air outlet device 100. When the controller 202 receives user location information transmitted by the human body information sensor 8, it can drive the first stepper motor 31 and the second stepper motor 41 to work according to a preset mode, thereby controlling the rotation of the turntable 2 and the oscillation of the air guide plate 42, and thus adjusting the air outlet direction of the air outlet device 100 to meet the user's functional needs for different air delivery directions. Specifically, the ceiling-mounted electrical appliance 1000 can be an air conditioner, a bathroom heater, a cooling heater, a fresh air system, etc.

[0062] In a specific embodiment, such as Figure 4 As shown, the aforementioned main unit 100 can be a structure directly corresponding to the air outlet device 100; for example... Figure 5 As shown, the host unit 100 can also be connected to the air outlet device 100 by setting a connecting duct 400.

[0063] In one specific embodiment, such as Figure 4As shown, the air outlet device 100 is located below the main unit 100, so that the air blown out by the main unit 100 is directly blown out through the air outlet device 100; preferably, in this embodiment, the air outlet device 100 can be directly inserted into the keel 300 of the integrated ceiling through the mounting frame 5, and the main unit 100 is fixed on the keel 300.

[0064] In another specific embodiment, such as Figure 5 As shown, the ceiling appliance 1000 also includes a connecting duct 400. The main unit 100 is connected to the air outlet device 100 through the connecting duct 400. The main unit 100 is provided with a main unit air outlet 201. The two ends of the connecting duct 400 are respectively fixed to the panel 1 of the air outlet device 100 and the main unit air outlet 201, and rotate in cooperation with the turntable 2 of the air outlet device 100. When the turntable 2 rotates, the connecting duct 400 remains fixed. Preferably, in this embodiment, the air outlet device 100 can be directly inserted into the keel 300 of the integrated ceiling through the mounting frame 5. The main unit 100 can be installed and fixed on the keel 300, or it can be installed through a hanging rod. In this embodiment, except that the air outlet of the main unit 100 needs to pass through the connecting duct 400 to enter the air outlet device 100, the rest of the principle is the same as that of the previous embodiment. Figure 4 The embodiments shown are the same and will not be described again here.

[0065] A schematic diagram of the system structure of the ceiling electrical appliance 1000, as shown below. Figure 6 As shown, the first stepper motor 31, the second stepper motor 41, and the human body information sensor 8 of the air outlet device 100 are connected to the controller 202 inside the host 100. When the controller 202 receives the user's location and status information transmitted by the human body information sensor 8, it can drive the first stepper motor 31 and the second stepper motor 41 to work according to the preset mode, thereby controlling the rotation of the turntable 2 and the swing of the air guide plate 42, thereby adjusting the air outlet direction of the air outlet device 100, so as to meet the user's functional needs for different air supply directions.

[0066] like Figure 7 As shown, this disclosure also provides a control method for a ceiling electrical appliance 1000, used to control the ceiling electrical appliance 1000 in any of the above embodiments, including the following steps:

[0067] S11, obtain the air supply mode input by the user, the air supply mode is either wind blowing on people mode or wind avoiding people mode;

[0068] S12, acquire user location information detected by human body information sensor 8;

[0069] S13, based on the air supply mode and user location information, controls the rotation of the turntable 2 and the oscillation of the air guide plate 42.

[0070] In some embodiments, such as Figure 8As shown, the air supply modes include a "blowing-to-person" mode and a "wind-avoiding-person" mode. When the air outlet device 100 is in "blowing-to-person" mode, the human body information sensor 8 detects the user's location information and transmits it to the controller 202. The controller 202 controls the first stepper motor 31 and the second stepper motor 41 to rotate based on the received user location information, thereby adjusting the angle between the turntable 2 and the air guide plate 42, so that the air blown by the air outlet device 100 can directly blow onto the human body. When the air outlet device 100 is in "wind-avoiding-person" mode, the human body information sensor 8 detects the user's location information and transmits it to the controller 202. The controller 202 determines whether the air is directly blowing onto the human body based on the received user location information. If the air is not directly blowing onto the human body, the turntable 2 and the air guide plate 42 remain in their original positions. If the air is directly blowing onto the human body, the controller controls the first stepper motor 31 and the second stepper motor 41 to rotate and adjust the angle between the turntable 2 and the air guide plate 42, so that the air avoids the human body.

[0071] In some embodiments, such as Figure 9 As shown, based on the air supply mode and user location information, the rotation of the turntable 2 and the oscillation of the air guide plate 42 are controlled, including:

[0072] S131, with the longitudinal symmetry plane of the air guide plate 42 in the initial state of the air outlet device 100 as the dividing line (e.g. Figure 9 The dashed lines shown divide the detection area into a first region and a second region (as indicated). Figure 9 (As shown in regions A and B).

[0073] It should be noted that, Figure 9 This is a top view of a ceiling appliance installed in a room ceiling according to an embodiment of the present disclosure. The squares in the figure represent integrated ceiling panels, and the outer ring represents the wall.

[0074] It should be understood that when the ceiling electrical appliance 1000 is in a non-working state, the turntable and air guide plate of the air outlet device 100 are reset to the initial state position. In the initial state position, the air guide plate is in a horizontal state to block the air outlet on the turntable. The longitudinal symmetry plane of the air guide plate 42 is also the vertical symmetry plane of the air guide plate along the length direction when the air guide plate is in a horizontal state.

[0075] In practice, the air guide plate can rotate 90 degrees in each of two directions from its initial position. When the air guide plate rotates (or swings) a certain angle in one direction, it directs the air to the first area, at which point the second area is not exposed to direct airflow. When the air guide plate rotates (or swings) a certain angle in the other direction, it directs the air to the second area, at which point the first area is not exposed to direct airflow.

[0076] S132, Determine the user's location area based on the user's location information;

[0077] In other words, based on the user's location information detected by the human body information sensor, it can be determined whether the user is in the first or second area, thus facilitating the control of the swing direction of the air guide plate according to the area where the user is located.

[0078] S133, depending on the air supply mode and the area where the user is located, control the air guide plate 42 to open towards the side where the user is located (when the air supply mode is the wind blowing to people mode), or control the air guide plate 42 to open away from the side where the user is located (when the air supply mode is the wind avoiding people mode).

[0079] In other words, the swing direction of the air guide plate is controlled according to whether the air supply mode is "wind blowing on people" or "wind avoiding people", thus making it easier to control whether the wind blows on people or avoids people.

[0080] Furthermore, such as Figure 10 and Figure 11 As shown, when the air supply mode is set to "wind blowing on people":

[0081] Depending on the air supply mode and the area where the user is located, the air guide plate 42 is controlled to open towards the side of the user's area;

[0082] Calculate the angle α between the user's horizontal coordinates and the horizontal airflow direction of the initial position air guide plate 42, and control the rotation angle of the turntable 2 according to the angle α;

[0083] Calculate the angle β between the user's coordinates and the vertical direction, and control the swing angle of the air guide plate 42 based on the angle β.

[0084] It should be noted that the user's coordinates can be determined using the location of the human information sensor as the origin (or the center of the air guide plate of the air outlet as the origin). Based on the user's position relative to the air outlet 100, the required rotation angle of the turntable 2 and the required swing angle of the air guide plate 42 can be calculated.

[0085] In practical implementation, for example, when a user is detected to be in a certain position... Figure 10 and Figure 11 When the position is shown, the rotation of turntable 2 can be controlled according to the included angle α (as shown). Figure 10 The rotation angle α (clockwise as shown) controls the swing of the air guide plate 42 according to the included angle β (as shown). Figure 11 The counterclockwise swing angle β, as shown, ensures that the wind direction is directly facing the user, thus achieving the purpose of the wind blowing on the person.

[0086] It should be noted that when the air supply mode is in the "wind avoids people" mode, simply control the air guide plate 42 to open towards the side opposite the user's location, depending on the area the user is in. In other words, if the user is in the first area, simply control the air guide plate to open towards the side of the second area. Of course, when the air supply mode is in the "wind avoids people" mode, it can also be achieved by controlling the rotation of the turntable, or by controlling the rotation of the turntable and the swing of the air guide plate, or by controlling the air guide plate to swing to a position where it is almost impossible for anyone to be present.

[0087] In summary, the air outlet device, ceiling electrical appliance, and control method provided in this disclosure, compared with the air outlet device of traditional ceiling electrical appliances, can adjust the air supply direction and expand the air supply range by driving the rotation of the turntable and the swing of the air guide plate through the drive mechanism; and can automatically adjust the air supply direction according to the user's position information by detecting the user's position information through the human information sensor, so as to realize the function of blowing on people and avoiding people, thereby improving the user experience.

[0088] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0089] The above description is merely a specific embodiment of this disclosure, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure.
