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 air conditioner has a ring-shaped air outlet to enable 360° circular air delivery. However, the ceiling air conditioner in this technology has poor air sweeping effect, making it difficult to evenly distribute the airflow to all parts of the indoor space, resulting in 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 poor air sweeping effect of the ceiling-mounted air conditioner.

[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, and the air outlet is connected to the air duct.

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

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

[0011] When the first air guide ring opens the air outlet and the second air guide ring is within the first height range, the second air guide ring defines the air outlet direction; when the first air guide ring opens the air outlet and the second air guide ring is within the second height range, the first air guide ring and the second air guide ring together define the air outlet direction.

[0012] In one possible implementation, the second air guide ring includes a first air guide portion and a second air guide portion connected in sequence. The first air guide portion is provided with a first air guide surface, and the second air guide portion is provided with a second air guide surface. The first air guide surface is connected to the second air guide surface.

[0013] When the first air guide ring opens the air outlet and the second air guide ring is located within the first height range, the first air guide surface and the second air guide surface together define the air outlet direction.

[0014] In one possible implementation, the angle between the tangent of the second air guide surface at the end away from the first air guide surface and the vertical direction is α, where 30°≤α≤40°.

[0015] In one possible implementation, the first air guide ring is provided with an air-guiding surface;

[0016] When the first air guide ring opens the air outlet and the first air guide ring is located within the first height range, the first air guide surface, at least a portion of the second air guide surface, and the air intake surface together define the air outlet direction.

[0017] In one possible implementation, the length of the air-drawing surface in the horizontal direction is L, where 20mm ≤ L ≤ 40mm.

[0018] In one possible implementation, the first air guide ring has a fitting groove, and when the second air guide ring moves to abut against the first air guide ring, the end of the second air guide portion away from the first air guide portion is placed into the fitting groove.

[0019] In one possible implementation, a sealing plate is provided on the side of the second air guide ring near the first air guide ring, and a sealing groove is provided on the side of the first air guide ring near the second air guide ring to engage with the sealing plate; and / or, a sealing plate is provided on the side of the first air guide ring near the second air guide ring, and a sealing groove is provided on the side of the second air guide ring near the first air guide ring to engage with the sealing plate.

[0020] In one possible implementation, the body is provided with a return air component, the second air guide ring is movably sleeved on the return air component, and the first air guide ring is movably sleeved on the second air guide ring.

[0021] In one possible implementation, the return air component includes a return air section and a windbreak section, the second air guide ring is movably sleeved on the return air section, and the windbreak section is disposed in the air duct to guide the outgoing air away from the gap where the return air section and the second air guide ring are sleeved.

[0022] 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.

[0023] Compared with the prior art, this application has the following beneficial effects:

[0024] The air guiding structure provided in this application embodiment, by movably setting the first and second air guiding rings, allows the first air guiding ring to close the air outlet when the ceiling-mounted air conditioner is off, thereby reducing the entry of dust, insects, and moisture into the machine body and extending the service life of the machine. When the first air guiding ring opens the air outlet, and the second air guiding ring is within a first height range, the airflow is guided only by the second air guiding ring, which helps to increase the maximum airflow range. When the second air guiding ring descends to abut against the first air guiding ring, the airflow is guided by both the second and first air guiding rings, further increasing the maximum airflow range. When the second air guiding ring is within a second height range, the airflow can pass sequentially through the second air guiding ring and at least part of the first air guiding ring. By changing the height of the second air guiding ring, the influence of the first air guiding ring on the airflow can be changed, thereby changing the airflow angle. This allows the airflow to be blown out at multiple continuous angles, ensuring that the airflow is evenly delivered to various locations in the indoor space, solving the problem of poor sweeping effect in ceiling-mounted air conditioners.

[0032] 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.

[0033] 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.

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0035] 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.

[0036] Please see Figure 1 and Figure 2 This application provides an air guiding structure, including a body 1, a first air guiding ring 2, and a second air guiding ring 3. The body 1 is provided with an air duct 11 and an air outlet 12, the air outlet 12 being connected to the air duct 11. The first air guiding ring 2 is movably mounted on the body 1 via a first lifting mechanism to open and close the air outlet 12. The second air guiding ring 3 is movably mounted between the body 1 and the first air guiding ring 2 via a second lifting mechanism.

[0037] When the first air guide ring 2 opens the air outlet 12 and the second air guide ring 3 is located within the first height range, the second air guide ring 3 defines the air outlet direction; when the first air guide ring 2 opens the air outlet 12 and the second air guide ring 3 is located within the second height range, the first air guide ring 2 and the second air guide ring 3 together define the air outlet direction.

[0038] By movably configuring the first air guide ring 2 and the second air guide ring 3, the first air guide ring 2 can be controlled to close the air outlet 12 when the ceiling-mounted unit is off, thereby reducing the entry of dust, insects, moisture, etc., into the unit 1 and extending the service life of the unit 1. When the first air guide ring 2 opens the air outlet 12, and the second air guide ring 3 is within the first height range, the airflow is guided only by the second air guide ring 3, which helps to increase the maximum airflow range. When the second air guide ring 3 descends to abut against the first air guide ring 2, the airflow is guided by both the second air guide ring 3 and the first air guide ring 2, which also helps to increase the maximum airflow range. When the second air guide ring 3 is within the second height range, the airflow can flow sequentially through the second air guide ring 3 and at least part of the first air guide ring 2. By changing the height of the second air guide ring 3, the influence of the first air guide ring 2 on the airflow can be changed, thereby changing the airflow angle. This allows the airflow to be blown out at multiple continuous angles, ensuring that the airflow is evenly delivered to various locations in the indoor space, solving the problem of poor sweeping effect of the ceiling-mounted unit.

[0039] It should be noted that the first lifting mechanism is used to drive the first air guide ring 2 to rise or fall, and the second lifting mechanism is used to drive the second air guide ring 3 to rise or fall. There are various ways to implement the first lifting mechanism and the second lifting mechanism, which are not limited here.

[0040] Please see Figure 1 and Figure 4 The body 1 includes a body 13, a panel 14, a return air component 15, and a filter 16. The panel 14 is fixedly connected to the bottom side of the body 13. The first air guide ring 2 is directly opposite the air outlet 12. The first lifting mechanism drives the first air guide ring 2 to move upward until it is in close contact with the panel 14, thereby closing the air outlet 12. The first lifting mechanism drives the first air guide ring 2 away from the panel 14, thereby opening the air outlet 12 with the second air guide ring 3.

[0041] Please see Figure 1 and Figure 2 The return air component 15 is disposed within the body 13, and the return air component 15 and the body 1 together define the air outlet duct 11. The second air guide ring 3 is movably sleeved on the return air component 15, and the first air guide ring 2 is movably sleeved on the second air guide ring 3. Specifically, the return air component 15 includes a return air section 151, and the second air guide ring 3 includes a connecting section 33. Both the return air section 151 and the connecting section 33 are arranged in a ring shape. The connecting section 33 is movably sleeved on the return air section 151, and the first air guide ring 2 is movably sleeved on the connecting section 33. The filter screen 16 is fixedly connected to the bottom side of the first air guide ring 2, so that the return air of the air conditioner can sequentially pass through the filter screen 16, the first air guide ring 2, and the second air guide ring 3 into the return air component 15, thus meeting the return air requirements of the air conditioner.

[0042] Please see Figure 1 and Figure 2In addition, the return air component 15 also includes a windbreak 152, which is connected to the outer side of the return air component 151 and located in the air duct 11 to guide the air out of the gap between the return air component 151 and the connecting part 33, thereby reducing condensation and abnormal noise caused by the air out entering the return air component 15 from the gap between the return air component 151 and the connecting part 33.

[0043] Please see Figure 2 and Figure 3 The second air guide ring 3 also includes a first air guide section 31 and a second air guide section 32. One end of the first air guide section 31 is connected to the outer ring surface of the connecting section 33, and the second air guide section 32 is connected to the end of the first air guide section 31 away from the connecting section 33. The upper side of the first air guide section 31 is provided with a first air guide surface 311, and the upper side of the second air guide section 32 is provided with a second air guide surface 321. The first air guide surface 311 is a concave arc surface, and the second air guide surface 321 is a convex arc surface. The first air guide surface 311 and the second air guide surface 321 are connected. When the second air guide ring 3 is located within the first height range, the airflow direction is guided and modified to the tangential direction of the end of the second air guide surface 321 away from the first air guide surface 311. The airflow flowing along the tangential direction is affected by the return airflow flowing along the vertical direction, causing the airflow angle to be deflected to the vertical or near-vertical direction, so that the airflow can quickly reach the ground.

[0044] Please see Figure 2 and Figure 3 The angle between the tangent of the end of the second air guide surface 321 away from the first air guide surface 311 and the vertical direction is α, where 30°≤α≤40°. In this embodiment, the value of α is 35°. In some embodiments of this application, the value of α is any one of 30°, 31°, 32°, 33°, 34°, 36°, 37°, 38°, 39°, and 40°. When α < 30°, even if the second air guide ring 3 is located within the first height range, the first air guide ring 2 can easily affect the airflow exiting the second air guide surface 321. When α > 40°, the return air is unlikely to affect the airflow flowing along the tangential direction and deflect it to the vertical direction. By making 30°≤α≤40°, it is not only beneficial to make the airflow exiting the second air guide surface 321 deflect to the vertical direction under the influence of the return air, but also beneficial to reduce the influence of the first air guide ring 2 on the airflow.

[0045] It should be noted that in this embodiment, when the tangent of the second air guide surface 321 at the end away from the first air guide surface 311 passes through the first air guide ring 2, the second air guide ring 3 is located within the second height range; when the tangent of the second air guide surface 321 at the end away from the first air guide surface 311 is located above the first air guide ring 2, the second air guide ring 3 is located within the first height range.

[0046] Please see Figure 2 and Figure 3The first air guide ring 2 is provided with an air-guiding surface 21, which is located on the top side of the first air guide ring 2. In this embodiment, the first air guide surface 311 is planar and horizontally arranged to guide the airflow passing through the first air guide surface 311 to flow horizontally. The length of the air guide surface 21 in the horizontal direction is L, specifically, the width of the air guide surface 21 is L, 20mm≤L≤40mm. In this embodiment, the width of the air guide surface 21 is 30mm. In some embodiments of this application, the width of the air guide surface 21 is any value among 20mm, 22mm, 24mm, 26mm, 28mm, 32mm, 34mm, 36mm, 38mm, and 40mm. By ensuring that 20mm≤L≤40mm, not only can the guiding effect of the air guide surface 21 be ensured, but the size of the first air guide ring 2 can also be reduced.

[0047] Please see Figure 2 and Figure 3 To further enhance the airflow effect of the first air guide ring 2, a fitting groove 22 is provided on the top side of the first air guide ring 2. When the first air guide ring 2 opens the air outlet 12 and the second air guide ring 3 abuts against the first air guide ring 2, the end of the second air guide portion 32 away from the first air guide ring 2 is placed into the fitting groove 22. This reduces the pressure loss when the air flows from the second air guide surface 321 to the air intake surface 21, increases the air delivery distance, and thus enhances the airflow effect of the first air guide ring 2.

[0048] Please see Figure 2 and Figure 3 In addition, in this embodiment, a sealing plate 34 is integrally formed on the side of the second air guide ring 3 near the first air guide ring 2, and a sealing groove 23 is formed on the side of the first air guide ring 2 near the second air guide ring 3 to engage with the sealing plate 34. In some embodiments of this application, a sealing plate 34 is integrally formed on the side of the first air guide ring 2 near the second air guide ring 3, and a sealing groove 23 is formed on the side of the second air guide ring 3 near the first air guide ring 2 to engage with the sealing plate 34. The engagement of the sealing plate 34 and the sealing groove 23 can reduce the flow of air from the gap where the first air guide ring 2 and the second air guide ring 3 fit together into the return air component 15, thereby reducing condensation and abnormal noise.

[0049] 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.

[0050] 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.

[0051] 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.
