Description

Technical Field

[0001] This application belongs to the field of air conditioning technology, and particularly relates to air guide structures and ceiling-mounted units. Background Technology

[0002] Ceiling-mounted air conditioners, also known as recessed ceiling air conditioners, can be installed in the interior ceiling. Compared to conventional air conditioning equipment, ceiling-mounted units do not occupy low-ceiling space, and therefore are increasingly widely used in public places.

[0003] In related technologies, a ceiling-mounted air conditioner has a ring-shaped air outlet to enable 360° circular airflow. However, the airflow range of this type of ceiling-mounted air conditioner is narrow, resulting in uneven temperature distribution in different parts of the indoor space and poor comfort.

[0004] Therefore, improvements to existing technologies are necessary.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0006] This application provides an air guide structure and a ceiling-mounted air conditioner to solve the problem of narrow air delivery range of ceiling-mounted air conditioners.

[0007] In a first aspect, embodiments of this application provide an air guiding structure, including:

[0008] The body is provided with an air duct and an air outlet communicating with the air duct;

[0009] The second air guide ring is movably mounted on the body via the second lifting mechanism to open and close the air outlet;

[0010] The first air guide ring is movably disposed between the body and the second air guide ring via the first lifting mechanism;

[0011] When the second air guide ring opens the air outlet, a first air duct is defined between the first air guide ring and the body, and a second air duct is defined between the second air guide ring and the first air guide ring. The ratio of the air volume of the first air duct to the air volume of the second air duct changes with the change of the position of the first air guide ring.

[0012] In one possible implementation, the first air guide ring is provided with a first air guide surface and a second air guide surface, the first air guide surface and the bottom end of the body define a first air duct, and the second air guide surface and the first air guide ring define a second air duct.

[0013] In one possible implementation, the second air guide ring is provided with a third air guide surface and a fourth air guide surface connected together. The second air guide surface matches the fourth air guide surface, and the first air guide surface matches the panel of the body. When the first air guide ring moves to the point where the second air guide surface and the fourth air guide surface are in contact, the third air guide surface, the first air guide surface, and the panel define a first air outlet direction. When the first air guide ring moves to the point where the first air guide surface and the panel are in contact, the second air guide surface, the third air guide surface, and the fourth air guide surface define a second air outlet direction.

[0014] In one possible implementation, the first air guide ring is provided with air guide holes, which are used to guide at least a portion of the airflow in the first air duct to mix with the airflow in the second air duct.

[0015] In one possible implementation, the cross-sectional area of ​​the air guide hole at the end closer to the body is greater than the cross-sectional area of ​​the end farther from the body.

[0016] In one possible implementation, the angle between the core axis of the air guide hole and the horizontal direction is α, where 30°≤α≤45°.

[0017] In one possible implementation, the width of the first air guide ring is 'a', and the width of the second air guide ring is 'b'.

[0018] In one possible implementation, the first air guide ring is concentrically arranged with the air outlet, and the inner diameter of the first air guide ring is not less than the outer diameter of the air outlet.

[0019] In one possible implementation, the machine body includes a body and a return air component. The bottom side of the body has an opening, and the return air component is disposed on the bottom side of the body. The body and the return air component define an annular air outlet, and the second lifting mechanism is disposed on the return air component.

[0020] Secondly, embodiments of this application also provide a ceiling machine, the ceiling machine including the air guiding structure as described in any of the preceding claims.

[0021] Compared with the prior art, this application has the following beneficial effects:

[0022] The air guiding structure provided in this application defines a first air duct between a first air guide ring and the bottom of the unit, and a second air guide ring between the first and second air guide rings. This allows airflow from the outlet to flow into both the first and second air ducts. The airflow from the first and second air ducts merges on one side of the first air guide ring. The direction of the merging airflow is deflected compared to the airflow from the outlet. By adjusting the height of the first air guide ring, the ratio of airflow flowing into the first and second air ducts can be adjusted, thereby regulating the deflection angle of the merging airflow. Adjusting the height of the first air guide ring to regulate the deflection angle of the merging airflow improves the maximum outlet angle of the ceiling-mounted air conditioner, solving the problem of narrow air delivery range.

[0031] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0032] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0034] This application provides an air guide structure and a ceiling-mounted air conditioner to solve the problem of narrow air delivery range of ceiling-mounted air conditioners. The following description will be provided in conjunction with the accompanying drawings.

[0035] Please see Figure 1 and Figure 2 This application provides an air guiding structure. The main body has an air duct and an air outlet communicating with the air duct. A second lifting mechanism is movably mounted on the main body to open and close the air outlet. A first lifting mechanism is movably mounted between the main body and a second air guiding ring. When the second air guiding ring opens the air outlet, a first air duct is defined between the first air guiding ring and the main body, and a second air duct is defined between the second air guiding ring and the first air guiding ring. The ratio of the air volume output from the first air duct to the air volume output from the second air duct changes with the position of the first air guiding ring.

[0036] By defining a first air duct 4 between the first guide ring 2 and the bottom of the body 1, and defining a second air duct 5 between the second guide ring 3 and the first guide ring 2, the airflow from the outlet 14 flows into the first air duct 4 and the second air duct 5 respectively. The airflow from the first air duct 4 and the airflow from the second air duct 5 merge on one side of the first guide ring 2. The direction of the merging airflow is deflected compared to the airflow from the outlet 14. Furthermore, by adjusting the height of the first guide ring 2, the ratio of the airflow flowing into the first air duct 4 to the airflow flowing into the second air duct 5 can be adjusted, thereby adjusting the deflection angle of the merging airflow. By adjusting the height of the first guide ring 2 to adjust the deflection angle of the merging airflow, the maximum air outlet angle of the ceiling-mounted air conditioner is improved, solving the problem of the narrow air supply range of the ceiling-mounted air conditioner.

[0037] Please see Figure 2 and Figure 3In this embodiment, the body 1 is used to realize the air supply and return of the air conditioner. The body 1 includes a main body 11, a return air component 12, and a panel 13. An opening is provided on the bottom side of the main body 11. The panel 13 is fixedly connected to the bottom side of the main body 11. One end of the return air component 12 extends into the main body 11 from the opening and is fixedly connected to the main body 11 through a connector. The return air component 12 is cylindrical. A filter screen 15 is provided at the bottom of the return air component 12 so that the return air of the air conditioner can pass through the filter screen 15 and enter the return air component 12. The main body 11 and the return air component 12 define an air outlet 14. A second air guide ring 3 is connected to the return air component 12 through a second lifting mechanism. A first air guide ring 2 is movably disposed between the panel 13 and the second air guide ring 3 through a first lifting mechanism.

[0038] Please see Figure 2 and Figure 3 The second air guide ring 3 is provided with a third air guide surface 31 and a fourth air guide surface 32 connected to each other. The second air guide surface 22 matches the fourth air guide surface 32, and the first air guide surface 21 matches the panel 13 of the body 1. When the first air guide ring 2 moves to the point where the second air guide surface 22 and the fourth air guide surface 32 are in contact, the third air guide surface 31, the first air guide surface 21 and the panel 13 define the first air outlet direction. When the first air guide ring 2 moves to the point where the first air guide surface 21 and the panel 13 are in contact, the second air guide surface 22, the third air guide surface 31 and the fourth air guide surface 32 define the second air outlet direction.

[0039] Please see Figure 2 and Figure 3 Specifically, in this embodiment, the first air guide ring 2 is provided with a first air guide surface 21 and a second air guide surface 22, and the second air guide ring 3 is provided with a third air guide surface 31 and a fourth air guide surface 32. The third air guide surface 31 faces the air outlet 14, and the fourth air guide surface 32 is connected to the side of the third air guide surface 31 and the second air guide ring 3. In this embodiment, the first air guide surface 21 is a horizontally arranged plane, the second air guide surface 22 and the third air guide surface 31 are both concave curved surfaces, and the fourth air guide surface 32 is an outwardly convex curved surface. A first air duct 4 is defined between the first air guide surface 21 and the side of the panel 13 away from the body 1, and a second air duct 5 is defined between the second air guide surface 22 and the third air guide surface 31. The first air duct 4 is used to guide the airflow to flow horizontally, and the second air duct 5 is used to guide the airflow to flow obliquely downward. The air outlets of the first air duct 4 and the second air duct 5 can merge obliquely downward from the first air guide ring 2. The direction of the merging airflow is deflected compared to the airflow flowing out from the air outlet 14. The height of the first air guide ring 2 can be adjusted by the first lifting mechanism, thereby adjusting the ratio of the airflow flowing into the first air duct 4 and the airflow flowing into the second air duct 5, and thus adjusting the deflection angle of the merging airflow.

[0040] Please see Figure 4 and Figure 5When the first air guide ring 2 rises to the bottom side of the body 1, the first air guide surface 21 abuts against the panel 13, causing the airflow from the air outlet 14 to flow directly to the second air guide ring 3. The airflow is then guided by the third and fourth guide surfaces sequentially and blown diagonally downwards from the second air guide ring 3. When the first air guide ring 2 lowers to connect with the second air guide ring 3, the second air guide surface 22 abuts against the fourth air guide surface 32, causing the airflow from the air outlet 14 to flow directly to the second air guide ring 3. The airflow is then guided by the third and first guide surfaces sequentially and blown horizontally. When the first air guide ring 2 moves to the bottom side of the body 1 and between the second air guide ring 3, the airflow from the air outlet 14 flows into the first air duct 4 and the second air duct 5 respectively. The airflow from the first air duct 4 and the airflow from the second air duct 5 merge and are blown out diagonally downwards from the first air guide ring 2.

[0041] Please see Figure 4 The width of the first air guide ring 2 is 'a', and the width of the second air guide ring 3 is 'b'. In this embodiment, when At that time, the width of the first guide ring 2 is relatively short, resulting in a poor effect of the first guide ring 2 in dividing the airflow blown from the air outlet 14, and a poor effect in adjusting the deflection angle of the converging airflow when the first guide ring 2 rises and falls; when At that time, the width of the first guide ring 2 was too long, resulting in an excessively long length of the first air duct 4, making it difficult for the airflow from the first air duct 4 to merge with the airflow from the second air duct. At the same time, it can not only meet the needs of adjusting the deflection angle of the converging airflow when the first air guide ring 2 rises and falls, but also facilitate the merging of the air outlet of the first air duct 4 and the air outlet of the second air duct.

[0042] Please see Figure 2 and Figure 3 In this embodiment, the air outlet 14, the first air guide ring 2, and the second air guide ring 3 are all arranged in a circular shape. In some embodiments of this application, the air outlet 14, the first air guide ring 2, and the second air guide ring 3 are all arranged in an elliptical ring, a square ring, or a polygonal ring. In this embodiment, the first air guide ring 2 and the second air guide ring 3 are both concentrically arranged with the air outlet 14, and the inner ring diameter of the first air guide ring 2 is not less than the outer ring diameter of the air outlet 14. By making the inner ring diameter of the first air guide ring 2 greater than or equal to the outer ring diameter of the air outlet 14, excessive airflow from the air outlet 14 into the first air duct 4 when the first air guide ring 2 is close to the panel 13 is avoided, which would result in a deterioration in the air sweeping effect of the air conditioner.

[0043] Please see Figure 4 and Figure 5The first air guide ring 2 has an air guide hole 23. Specifically, the air guide hole 23 is formed on the first air guide surface 21. The air guide hole 23 is used to guide at least part of the airflow in the first air duct 4 to mix with the airflow in the second air duct 5. In this embodiment, the number of air guide holes 23 is set to one, and the size of the air guide hole 23 is relatively large. In some embodiments of this application, the number of air guide holes 23 is set to multiple, and the multiple air guide holes 23 are spaced apart to form a perforated structure. The setting of the air guide hole 23 can guide part of the airflow in the first air duct 4 to mix with the airflow in the second air duct 5 in advance. This can not only increase the initial velocity of the airflow at the outlet of the second air duct 5, but also increase the deflection angle of the airflow at the outlet of the second air duct 5, thereby reducing the occurrence of the airflow at the outlet of the second air duct 5 being drawn back into the return air member 12.

[0044] Please see Figure 5 In this embodiment, the angle between the axis of the air guide hole 23 and the horizontal direction is α, where 30°≤α≤45°. In this embodiment, the value of α is 30°. In some embodiments of this application, the value of α is any one of 33°, 36°, 39°, 41°, and 45°. By ensuring that 30°≤α≤45°, not only can the occurrence of air recirculation from the air conditioner's outlet be reduced, but the air sweeping effect of the air conditioner can also be improved.

[0045] Please see Figure 4 and Figure 5 The cross-sectional area of ​​the air guide hole 23 near the body 1 is larger than the cross-sectional area of ​​the air guide hole 23 away from the body 1. In this embodiment, the air guide hole 23 is a circular hole, and the diameter of the air guide hole 23 gradually decreases from the end near the body 1 to the end away from the body 1. This not only helps to increase the air inlet area of ​​the air guide hole, but also increases the speed of the airflow flowing out of the air guide hole 23.

[0046] This application also provides a ceiling-mounted air conditioner, which includes the air guiding structure described above. Since this ceiling-mounted air conditioner has the aforementioned air guiding structure, it possesses at least some or all of the beneficial effects of the aforementioned air guiding structure, which will not be elaborated upon here.

[0047] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0048] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
