Description

Technical Field

[0001] This utility model relates to the field of ceiling air conditioning technology, specifically to a ceiling air conditioning unit air outlet panel assembly and the ceiling air conditioning unit thereof. Background Technology

[0002] Ceiling-mounted air conditioners are a type of recessed air conditioner widely used in light commercial applications. Their indoor units typically consist of a main unit and a panel assembly. The panel assembly primarily serves as the air intake and exhaust system, with the exhaust areas generally distributed around the central air intake.

[0003] During the operation of a ceiling-mounted air conditioner, the airflow is easily drawn back into the air conditioner due to the air inlet position and air outlet direction, causing a backflow phenomenon that affects the cooling or heating effect. To improve this problem, existing technology usually adjusts the angle of the air guide vane in cooling mode to direct the cold air as far as possible to the surroundings, allowing the airflow to move away from the air inlet and then fall naturally, thereby reducing airflow backflow.

[0004] However, in heating mode, because hot air has the property of rising, directing the hot air away from the air inlet will cause the hot air to concentrate near the ceiling and make it difficult to flow back to the air inlet in time, resulting in low heating efficiency and uneven indoor temperature distribution. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a ceiling air outlet panel assembly and ceiling air outlet of the ceiling air conditioner, so as to solve the problem that the existing ceiling air outlet structure is simple and it is difficult to take into account the airflow guidance effect under both cooling and heating conditions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A ceiling-mounted air outlet panel assembly includes: The panel has an air inlet and at least one air outlet disposed around the air inlet; the air outlet has an inner wall near the air inlet and an outer wall near the periphery of the panel; wherein the outer wall and / or inner wall of the air outlet includes a fixed section and a flared section that connects to the outer end of the fixed section and extends outward. A deflector is installed on the inside of the air outlet and located between the inner and outer walls of the air outlet. An air guide plate is installed at the air outlet to cover or open the air outlet.

[0007] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting flared sections on the outer and / or inner walls of the air outlet, the airflow forms a diffusion and guiding effect when passing through the flared sections. This can effectively reduce the phenomenon of cold air recirculation along the ceiling in cooling mode, enhance the downward sinking of cold air, and improve the distribution of indoor airflow. In heating mode, the flared sections guide hot air to be delivered downwards over long distances, improving the uniformity and comfort of hot air in the space and avoiding the phenomenon of heat accumulation at the top.

[0008] 2. By installing a guide vane inside the air outlet, the airflow can be rectified and split a second time. Combined with the openable guide vane, the airflow direction becomes more focused and controllable, enabling multi-angle and multi-mode airflow guidance adjustment, thereby improving air delivery efficiency and air circulation effect.

[0009] Furthermore, each end of the air guide plate is provided with a mounting bracket, one of the mounting brackets is rotatably equipped with a drive shaft, and the other mounting bracket is rotatably equipped with a mounting shaft.

[0010] Furthermore, it also includes a motor mounted on the panel, which drives the drive shaft to rotate, thereby causing the air guide plate to rotate.

[0011] Furthermore, the fixed section is arranged in a vertical plane, and the flared section is a curved surface or an inclined surface that slopes from the inside out.

[0012] Furthermore, the panel is square in shape, and the panel has four air outlets, which are evenly arranged around the outer periphery of the air inlet.

[0013] Furthermore, the cross-section of the air outlet is arc-shaped, and the cross-section of the air guide plate is also arc-shaped to match the air outlet.

[0014] Furthermore, both sides of the guide plate are curved surfaces.

[0015] Furthermore, the air guide plate has a folded edge structure around its perimeter.

[0016] Furthermore, the panel is provided with an air intake grille at the air inlet.

[0017] This utility model also provides a ceiling-mounted air conditioner, including the above-mentioned ceiling-mounted air conditioner exhaust panel assembly. Attached Figure Description

[0019] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0021] In the description of this utility model, it should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0022] Example 1 like Figure 1-5As shown in the figure, this utility model embodiment proposes a ceiling air outlet panel assembly, including: a panel 10, having an air inlet 11 and at least one air outlet 12 disposed around the air inlet 11; the air outlet 12 has an inner sidewall 121 near the air inlet 11 and an outer sidewall 122 near the periphery of the panel 10; wherein the outer sidewall 122 and / or the inner sidewall 121 of the air outlet 12 includes a fixed section 12a and a flared section 12b extending outward from the outer end of the fixed section 12a; a guide plate 20, installed on the inner side of the air outlet 12 and located between the inner sidewall 121 and the outer sidewall 122 of the air outlet 12; and a guide vane 30, installed at the air outlet 12 for covering or opening the air outlet 12.

[0023] In this embodiment of the invention, when the air conditioner is running, the air processed by the heat exchanger is blown out from the air outlet 12. By providing a flared section 12b on the outer sidewall 122 and / or the inner sidewall 121 of the air outlet 12, the air outlet 12 forms an outwardly expanding airflow channel. When the airflow passes through the flared section 12b, its velocity gradually decreases and its flow direction becomes more dispersed. In cooling mode, this effectively prevents cold air from flowing back to the air inlet 11 along the ceiling, improves the downward effect of cold air, and makes the indoor temperature distribution more uniform. In heating mode, the structure of the flared section 12b can change the flow direction of the hot air, causing it to be sent downward at a larger angle, thereby reducing the phenomenon of hot air lingering near the ceiling, promoting the rapid circulation of hot air in the room, and improving heating efficiency and comfort.

[0024] Meanwhile, the guide vane 20, located inside the air outlet 12, performs secondary rectification and distribution of the airflow, making the airflow direction more stable, preventing turbulence, and improving the uniformity of air delivery. The air guide plate 30 is used to adjust the air outlet angle or close the air outlet 12 for flexible use in different operating modes. Thus, the overall structure of this utility model, through the synergistic effect of the flared section 12b, the guide vane 20, and the air guide plate 30, achieves the guidance and balanced distribution of airflow under cooling and heating conditions, improving the shortcomings of traditional ceiling-mounted air conditioners such as easy backflow and uneven temperature distribution, and has the advantages of excellent air delivery effect, high energy efficiency, and good comfort.

[0025] In this embodiment, the inner wall 121 and the outer wall 122 are preferably integrally formed into the air outlet 12. This integral forming method avoids problems such as air leakage and abnormal noise caused by assembly gaps or loose connections in traditional assembled structures, thereby improving the overall sealing and structural stability of the air outlet 12. It also reduces the number of parts and assembly steps, lowering production costs and improving manufacturing efficiency. Furthermore, the integral forming structure makes the air outlet channel smoother and reduces airflow resistance, which helps improve the uniformity of air delivery and the quietness of the operation.

[0026] Specifically, such as Figure 4-5 As shown in this embodiment of the invention, both ends of the air guide plate 30 are provided with mounting brackets 40. One mounting bracket 40 is rotatably equipped with a drive shaft 50, and the other mounting bracket 40 is rotatably equipped with a mounting shaft 60. The drive shaft 50 and the mounting shaft 60 cooperate to support the air guide plate 30, so that the air guide plate 30 can rotate around the axis, thereby realizing the adjustment of the air volume and air direction of the air outlet 12. Furthermore, in order to facilitate the automated control of the air guide plate 30, this embodiment has a motor 70 installed on the panel 10. The motor 70 drives the drive shaft 50 to rotate, thereby controlling the rotation of the air guide plate 30.

[0027] Specifically, one end of the drive shaft 50 has a polygonal structure (e.g., a regular hexagon or octagon), and the corresponding mounting bracket 40 has a polygonal hole that mates with it. The polygonal structure enables an anti-slip fit, ensuring that the drive shaft 50 will not slip or rotate relative to the shaft during rotation, thereby reliably transmitting the driving force to the air guide plate 30. At the same time, the polygonal hole and the polygonal shaft mate with each other, simplifying the installation process and enabling a stable connection without additional fasteners, thereby improving installation efficiency and structural reliability.

[0028] In this embodiment, the two ends of the air guide plate 30 and the mounting frame 40 are preferably integrally molded. The air guide plate 30 and the mounting frame 40 are connected by integral molding, which not only ensures the rotational stability of the air guide plate 30, but also reduces the number of parts, thereby reducing assembly difficulty and cost. At the same time, the integral molding structure also enhances the structural strength of the air guide plate 30 and ensures the reliability of long-term operation.

[0029] Specifically, such as Figure 2-3 As shown in the embodiment of this utility model, the fixed section 12a is arranged vertically, and the flared section 12b is curved or inclined from the inside out. By arranging the fixed section 12a vertically, the basic width of the air outlet 12 can be maximized, preventing the inner sidewall 121 from tilting towards the air inlet 11, which would cause some of the exhaust gas to flow directly back to the air inlet 11, thereby reducing the heat exchange efficiency of the ceiling-mounted air conditioner. Conversely, arranging the flared section 12b as curved or inclined from the inside out can effectively guide the exhaust airflow, ensuring uniform airflow diffusion, increasing the air supply range, and thus expanding the air supply coverage area. Therefore, by combining the vertical fixed section 12a with the curved or inclined flared section 12b, the air supply range, airflow guidance, and heat exchange efficiency can be balanced, thereby ensuring the comfort and energy efficiency of the ceiling-mounted air conditioner under various operating conditions.

[0030] It is worth mentioning that when the above-mentioned flared section 12b is a slope, it is slightly inclined downwards to avoid the problem of excessive upward or downward exhaust of air: if the flared section 12b is inclined too upwards, a large amount of airflow will blow directly onto the ceiling, affecting the uniformity of indoor temperature and possibly causing erosion of the ceiling; if it is inclined too downwards, the air supply range will be greatly reduced, affecting the cooling and heating effect.

[0031] Specifically, such as Figure 1 As shown, in this embodiment of the present invention, the panel 10 is square in shape, and the panel 10 has four air outlets 12, which are evenly arranged around the outer periphery of the air inlet 11. Furthermore, the air outlets 12 are elongated, extending along the side length of the panel 10. By evenly arranging four air outlets 12 around the air inlet 11, multi-directional and balanced airflow can be achieved, avoiding localized airflow backflow or insufficient airflow, thereby improving the uniformity of indoor temperature. It should be understood that each air outlet 12 has a fixed section 12a and a flared section 12b.

[0032] Specifically, such as Figure 2 As shown in the embodiment of this utility model, the cross-section of the air outlet 12 is arc-shaped, and the cross-section of the air guide plate 30 is also arc-shaped to match the air outlet 12. By cooperating with the arc-shaped air guide plate 30 and the arc-shaped air outlet 12, the airflow can flow smoothly out along the air outlet 12, reducing airflow turbulence and resistance, thereby reducing noise and improving air delivery efficiency; it also ensures uniform airflow distribution, improves indoor air circulation, and enhances the comfort and uniformity of cooling and heating; furthermore, the arc-shaped structure facilitates precise matching between the air guide plate 30 and the air outlet 12, meaning that when closed, the air guide plate 30 can completely close the air outlet 12, and when open, the air guide plate 30 can block the backflow area, reducing airflow backflow.

[0033] Specifically, such as Figure 2-3 As shown in this embodiment of the invention, both sides of the guide plate 20 have curved guide surfaces 21. The curved guide surfaces 21 can effectively guide the airflow to flow smoothly in a predetermined direction, reducing the generation of turbulence and local eddies, thereby reducing operating noise and improving air delivery efficiency.

[0034] Specifically, such as Figure 3-4 As shown in this embodiment of the invention, the air guide plate 30 has a folded edge structure 31 around its perimeter, so that an insulation pad (not shown in the figure) can be pasted on the inner side of the folded edge. By installing the insulation pad, the temperature difference on the surface of the air guide plate 30 can be effectively reduced, thereby avoiding the generation of condensation and preventing it from falling into the room. It should be understood that the insulation pad has little impact on the shape of the air guide plate 30 and the airflow direction, thus achieving the anti-condensation function while maintaining the air supply effect.

[0035] Specifically, such as Figure 1 As shown in this embodiment of the invention, the panel 10 is provided with an air inlet grille 13 at the air inlet 11. The air inlet grille 13 can perform preliminary rectification and filtration of the air entering the ceiling fan, preventing large dust particles or debris from entering the interior, thereby protecting the heat exchanger and fan components, and thus improving the reliability and service life of the overall device.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
