Detailed Implementation

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] As mentioned in the background section, most existing ceiling fan outlets use guide vanes for air sweeping. However, the sweeping range of a single guide vane is limited. Figures 1 to 4 As shown, ceiling fans can only output air within a predetermined angle range, resulting in limited coverage of the air outlet area. Therefore, to address the aforementioned technical problems, the ceiling fan provided in this application includes a body 100 and an air guide assembly 200. The body 100 has an air outlet 110, and the air guide assembly 200 is located at the air outlet 110. The air guide assembly 200 includes multiple air guide components 210, each with a blocking position for obstructing the air outlet 110 and a yielding position for avoiding the air outlet 110, allowing the air outlet 110 to be closed or opened. Each air guide component 210 is rotatably arranged so that airflow passes sequentially through each air guide component before being blown out, or is blown out between adjacent air guide components. The arrangement of multiple air guide components 210 allows for effective guidance and distribution of airflow, avoiding dead zones caused by a single air guide plate, thereby improving air delivery efficiency. Meanwhile, by blocking and avoiding the air outlet 110 through the air guide component 210, dynamic management can be achieved, further expanding the air supply range. Through the relative rotation of the air guide component 210, the air supply direction is no longer limited to a single angle, but can achieve a wider coverage by adjusting the position of each air guide component 210, thus enhancing the flexibility and controllability of air conditioning air supply.

[0037] Please refer to Figures 5 to 14This application provides a ceiling fan, including: a body 100 with an air outlet 110; and an air guide assembly 200 disposed at the air outlet 110. The air guide assembly 200 includes multiple air guide components 210, each of which has a blocking position for blocking the air outlet 110 and a clearance position for avoiding the air outlet 110, so that the air outlet 110 is closed or opened. The air guide components 210 are rotatably arranged so that airflow passes through each air guide component sequentially and is then blown out, or is blown out between two adjacent air guide components.

[0038] According to the ceiling fan provided in this application, each air guide component 210 can rotate relative to each other, realizing the diversification of air outlet direction and enabling wider radiation in both horizontal and vertical directions, thus meeting the air supply needs of large spaces. This design allows airflow to be guided to different directions, which not only enhances the coverage area of ​​the air outlet but also enables more complex airflow layouts.

[0039] Specifically, in the first embodiment provided in this application, such as Figures 5 to 8 As shown, each air guide component 210 is arranged side by side at the air outlet 110, and each air guide component 210 is connected to each other to close the air outlet 110; the airflow is blown out between two adjacent air guide components to open the air outlet 110.

[0040] In the first embodiment, the air guiding components 210 of the air guiding assembly 200 are installed side by side along the air outlet 110, forming a tight barrier. Each air guiding component 210 is driven by a third drive member 250, which is a drive motor. When all air guiding components 210 are in the closed position (blocked position), such as... Figure 5 As shown, they are connected to each other, completely blocking the air outlet 110, thus closing the air outlet. When some or all of the air guiding components 210 move to the avoidance position, such as Figures 6 to 8 As shown, an opening is formed between two adjacent air guiding components, allowing airflow to be blown out directly or indirectly through these opening areas, realizing the diffusion and directional delivery of airflow, thereby opening the air outlet 110.

[0041] When the air outlet 110 is opened, this embodiment takes two air guide components 210 as an example. The two air guide components 210 rotate relative to each other, and multiple air delivery angles can be formed between the two air guide components 210 to achieve composite guidance of airflow in the vertical and horizontal directions.

[0042] In the second embodiment provided in this application, each air guide component 210 includes a first air guide 211 and at least one second air guide 212. At least one second air guide 212 is disposed on the first air guide 211. The second air guide 212 is rotatably disposed relative to the first air guide 211. The airflow passes through the first air guide 211 and the second air guide 212 in sequence and is then blown out.

[0043] In this embodiment, the first air guide 211 serves as the basic air guiding structure, responsible for initially guiding the direction of the airflow. At least one second air guide 212 is disposed on the first air guide 211 and is capable of rotating relative to the first air guide 211. This design means that after the airflow passes through the first air guide, the subsequent path of the airflow can be changed by adjusting the angle of the second air guide 212, achieving secondary precise guidance of the airflow.

[0044] Due to the rotatable nature of the second air guide 212, it can deflect or directly release the airflow to different degrees depending on its position, thereby adjusting the airflow distribution pattern. For example, when long-distance delivery of hot or cold air is required, the second air guide 212 can be positioned at a more focused angle to enhance the airflow range; while when wide coverage is needed, the second air guide 212 can be positioned in a more dispersed state, allowing the airflow to cover a wider area.

[0045] The dual air guiding mechanism of the first and second air guiding components not only enables the initial orientation of airflow, but also allows for further refinement of airflow distribution through the fine-tuning control of the second air guiding component. This ensures both long-distance air delivery capability and near-field temperature balance.

[0046] In specific implementation, such as Figure 9 and Figure 10 As shown, the plurality of air guiding components 210 include: a first air guiding component 211, which is disposed at the air outlet 110 and is rotatably disposed around a first axis so that the air outlet 110 can be opened or closed; and a second air guiding component 212, which is disposed on the first air guiding component 211 and is rotatably disposed around a second axis so that the airflow is blown out after being guided by the first air guiding component 211 and the second air guiding component 212.

[0047] Unlike Embodiment 1, the second air guide 212 is not directly disposed at the air outlet, but is mounted on top of the first air guide 211. It is rotatable about a second axis, which means that it can further adjust the direction of airflow based on the first air guide 211, especially in the horizontal direction, to achieve finer airflow control and cover a wider area.

[0048] By combining the first air guide 211 and the second air guide 212, the air delivery angle can be adjusted not only in the vertical direction but also in the horizontal direction, greatly enhancing the range and flexibility of the air conditioning air delivery and ensuring the temperature balance of the entire space.

[0049] Along the direction of the airflow, the first air guide 211 includes a windward end 2110 and an air outlet end 2111; the second air guide 212 is disposed at the air outlet end 2111.

[0050] The air outlet 110, facing the main body 100, is the part where the airflow first contacts the first air guide 211. The design of the air-facing end needs to consider the smooth introduction of airflow and avoid excessive turbulence or noise. After passing through the interior or surface of the first air guide 211 from the air-facing end, the airflow flows out from the air outlet, ready to enter the second air guide 212 or be directly discharged into the indoor space.

[0051] The second air guide 212 is set at the air outlet 2111 of the first air guide 211. The purpose of this design is to allow the airflow to be adjusted or dispersed again by the second air guide 212 after the initial guidance of the first air guide 211, so as to achieve more precise air supply control.

[0052] Both the first air guide 211 and the second air guide 212 can rotate relative to each other via a drive mechanism (such as a motor). This independent control capability allows the air delivery direction and range to be adjusted in real time according to changes in the indoor environment or user needs, improving the flexibility and efficiency of air delivery.

[0053] In the specific implementation process, the second air guide 212 has an initial position and an open position. The second air guide 212 and the first air guide 211 are arranged parallel to each other so that the second air guide 212 is in the initial position.

[0054] The second air guide 212 is arranged parallel to the first air guide 211. In the initial position, the second air guide 212 and the first air guide 211 are aligned in the same direction, which usually means that they are in the closed state, jointly blocking the air outlet 110 and forming a closed air passage. Alternatively, the first air guide 211 and the second air guide 212 are aligned in the same direction.

[0055] In the third embodiment provided in this application, such as Figures 11 to 14As shown, the plurality of air guiding components 210 include: a first air guiding component 211, which is rotatably arranged around a third axis to open or close the air outlet 110, and has an installation opening 2112; and a second air guiding component 212, which is disposed at the installation opening 2112 and connected to the first air guiding component 211, and is rotatably arranged relative to the first air guiding component 211 around a fourth axis to allow airflow to be guided by the first air guiding component 211 and the second air guiding component 212 in sequence before being blown out.

[0056] The first air guide 211 can rotate around the third axis, which allows it to effectively open or close the air outlet 110, control the entry or exit of airflow, and thus regulate the air supply status of the air conditioner. The first air guide 211 is provided with an installation opening 2112, the purpose of which is to provide an installation position for the second air guide 212, so that the second air guide can be embedded therein without affecting the basic structure and function of the first air guide.

[0057] The second air guide 212 is precisely installed within the mounting opening 2112 of the first air guide 211. Its position and design ensure that the airflow is initially guided by the first air guide 211 and then further regulated by the second air guide. The second air guide 212 can rotate about a fourth axis, allowing it to be angularly adjusted relative to the first air guide 211 to change the direction of the airflow passing through the first air guide, thus achieving more precise airflow control.

[0058] The airflow first enters from the outlet 110 and, through the initial guidance of the first air guide 211, begins to change its original path. Subsequently, the airflow passes through the installation opening 2112 on the first air guide and encounters the second air guide 212. At this point, the second air guide 212 can further adjust the direction and intensity of the airflow according to its rotation angle around the fourth axis, thereby achieving secondary control and optimization of the airflow.

[0059] With the dual adjustment of the first air guide 211 and the second air guide 212, more precise control of airflow can be achieved, allowing users to adjust the air supply angle and direction according to room layout or personal preferences, significantly enhancing the adaptability and flexibility of the air conditioning air supply mode.

[0060] In the specific implementation process, such as Figure 14 As shown, the second air guide 212 is provided with a hollow structure 220, which extends along the length of the second air guide 212, and some airflow is blown out through the hollow structure 220.

[0061] The perforated structure 220 can take various shapes, such as groove, hole, and grid. The key is to ensure that when the airflow passes through the second air guide 212, a portion of it can penetrate directly through these perforations and be blown out, without having to completely follow the guidance of the second air guide 212.

[0062] By incorporating the perforated structure 220, even when the second air guide 212 is adjusted to a specific angle, the airflow can still diffuse to a wider area, avoiding localized temperature differences caused by overly concentrated airflow and improving the uniformity of indoor temperature. This not only improves the air delivery effect of the air conditioning system and reduces energy consumption, but also enhances user comfort, helps disperse and reduce airflow noise, and lowers operating noise.

[0063] Specifically, the hollow structure 220 includes: ventilation holes 221, which are disposed on the second air guide 212. There are multiple ventilation holes 221, which are spaced apart along the length of the second air guide 212.

[0064] The perforated structure 220 has multiple ventilation holes 221, which are evenly spaced along the length of the second air guide 212. This arrangement ensures that the airflow can be evenly dispersed through these holes when the second air guide is open, avoiding the problem of uneven airflow or local overheating or overcooling caused by the airflow concentrating at a certain point.

[0065] Ventilation holes 221 are round, elliptical or other shapes to reduce airflow resistance and ensure smooth airflow.

[0066] The opening and closing of the second air guide 212, and the presence of the ventilation hole 221, allow for a highly flexible air supply mode. When the second air guide 212 is closed, the airflow is directly directed to the air outlet 110; when the second air guide 212 is open, some airflow passes through the ventilation hole 221, forming a more dispersed and uniform air supply mode to meet the needs of different scenarios.

[0067] Furthermore, such as Figure 11 As shown, the second air guide 212 has a windward end face 2120 and a leeward end face 2121. The multiple air guide components 210 also include a third air guide 213, which is disposed on the leeward end face 2121 of the second air guide 212. The third air guide 213 is rotatably disposed relative to the second air guide 212 to block or avoid the hollow structure 220.

[0068] The windward end face 2120 of the second air guide 212 faces the first air guide 211 directly and receives the airflow guided by the first air guide; the leeward end face 2121 faces away from the airflow and is the last contact surface for the airflow to reach the next air guide element or directly enter the room.

[0069] The third air guide 213 is disposed on the leeward end face 2121 of the second air guide 212. This design means that after the airflow is guided by the hollow structure 220, it can be further regulated by the third air guide 213. At the same time, the third air guide 213 has the ability to rotate relative to the second air guide 212, which provides an additional dimension of control for the final path of the airflow.

[0070] By using the third air guide 213 to block the perforated structure 220 on the second air guide 212, the direction and flow of air can be effectively adjusted. Especially when it is necessary to concentrate or guide the airflow to a specific direction, or when a more uniform airflow distribution or an increased air supply range is required, the third air guide 213 can make way, that is, rotate to a position that allows the airflow to pass freely through the perforated structure 220, thereby promoting the diffusion of airflow.

[0071] The two ends of the second air guide 212 are respectively hinged to the first air guide 211 so as to rotate within the mounting opening 2112. The air guide assembly 200 also includes: a first driving member 230, which is disposed on the first air guide 211. The first driving member 230 is drivenly connected to the second air guide 212 so as to drive the second air guide 212 to rotate.

[0072] The two ends of the second air guide 212 are hinged to the first air guide 211. This hinged design allows the second air guide to rotate freely within a certain range without being restricted by the first air guide. This freedom provides the possibility for secondary airflow guidance, enabling the air supply system to be fine-tuned according to different scenarios or user needs, thus improving the accuracy and flexibility of air supply.

[0073] The first driving component (such as a motor) is mounted on the first air guide 211 and is driven to connect with the second air guide 212. This means that the first driving component can directly control the rotation of the second air guide, thereby adjusting the direction and intensity of the airflow. The introduction of this driving method ensures the stability and accuracy of the second air guide's rotation, avoiding the errors and inconveniences that may result from manual adjustment or indirect driving methods.

[0074] In this embodiment, the first air guide 211 has mounting holes at both ends, and the second air guide 212 has rotating shafts at both ends. The rotating shafts are inserted into the mounting holes, and the first drive member 230 is drivenly connected to the rotating shafts.

[0075] The body 100 is also provided with a second drive component 240, which is driven to connect with the first air guide component 211. The first drive component 230 and the second drive component 240 are controlled independently to make the first air guide component 211 and the second air guide component 212 rotate relative to each other.

[0076] In the ceiling fan provided in this application, the number of air guide components 210 is not limited; there can be one, two, or even more. The angle of the air guide component 210 in this application depends on the rotation of the drive motor. The air guide component is fixed on the moving part of the drive motor. When the drive motor receives an electrical signal, its moving part will rotate at a certain angle, thereby driving the air guide component fixed on the moving part to rotate at the corresponding angle.

[0077] When the drive motor receives a signal to return to the initial state, it will drive the air guide component to rotate to the closed state. When the drive motor receives an open state signal, it will drive the air guide component to rotate to the open state. The definition of the open state does not refer to an opening angle. Based on the simulation of the relevant airflow field, in order to meet customer needs and improve energy-saving effects, the opening state can be many angles, such as 30°, 60°, etc. This opening angle will be matched with different mode settings.

[0078] To meet the requirements of airflow guidance and aesthetics for large air vents, multiple air guide components can be used; this example uses two air guide plates. When the drive motor receives an activation command, it will rotate the air guide component to the corresponding angle to achieve the airflow guidance function. If this unit has two air guide components, different combinations of the number of components can be activated depending on the setting mode. For example, the first air guide component 211 can be activated while the second air guide component 212 is closed, or the second air guide component 212 can be activated while the first air guide component 211 is closed.

[0079] To address the limitation of some air conditioning products, such as ceiling-mounted units, having a relatively singular air outlet area, this application incorporates a second air guide component 212 to increase the airflow direction and outlet coverage area. The function and principle of this second air guide component 212 will be explained here as an example. Figure 11 When the first driving component 230 receives the signal to return to the initial state, it will drive the second air guide component 212 to the closed state; for example Figure 12 When the first drive component 230 receives the activation signal, it will drive the second air guide component 212 to the deployed state. When the second air guide component 212 is deployed, the outflow area of ​​the air outlet will decrease. Compared with when the second air guide component 212 is not deployed, its air outlet pressure will increase as the air outlet area decreases, and the corresponding initial air outlet velocity will increase, thereby allowing the air outlet to cover a farther area.

[0080] To further optimize the coverage of the air outlet range, considering that the second air guide 212 neglects part of the air outlet coverage directly below it in order to increase the air outlet velocity, such as Figure 14The second form of the second air guide 212 increases the airflow velocity while also ensuring that the airflow covers the area directly below. The middle section of the second air guide 212 is a perforated area, allowing some airflow to cover the lower area even when the second air guide 212 is open. Furthermore, a third air guide 213 is provided on the leeward end face 2121 of the second air guide 212, which further guides the airflow from the perforated area.

[0081] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0082] According to the ceiling fan provided in this application, it includes a body 100 and an air guide assembly 200. The body 100 is provided with an air outlet 110, and the air guide assembly 200 is located at the air outlet 110. The air guide assembly 200 includes a plurality of air guide components 210. Each air guide component 210 has a blocking position for blocking the air outlet 110 and a clearance position for avoiding the air outlet 110, so that the air outlet 110 is closed or opened. The air guide components 210 are rotatably arranged so that the airflow flows through each air guide component in sequence and is blown out, or is blown out between two adjacent air guide components.

[0083] The arrangement of multiple air guide components 210 allows for effective guidance and distribution of airflow, avoiding dead zones caused by a single air guide plate and thus improving air delivery efficiency. Simultaneously, the blocking and avoidance by the air guide components 210 enables dynamic management of the air outlet 110, further expanding the air delivery range. Through the relative rotation of the air guide components 210, the airflow direction is no longer limited to a single angle; instead, wider coverage can be achieved by adjusting the position of each air guide component 210, enhancing the flexibility and controllability of the air conditioning system.

[0084] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0085] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below."
