Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning technology, specifically to a ceiling-mounted air conditioning unit. Background Technology
[0002] Ceiling-mounted or recessed air conditioners, also known as ceiling-mounted units, are widely used due to their space-saving and aesthetically pleasing design.
[0003] Currently, ceiling-mounted air conditioners often use a method where the air outlets are located on the frame, typically four in number. Air is directed from the ceiling into the room at specific angles, meaning air is delivered in four directions along the angles set at each of the four outlets. However, because the air outlets form an angle with the horizontal plane of the ceiling, and the airflow direction is limited, when the air conditioner is in cooling mode, the cold air blows directly downwards. If someone is near the air conditioner, the cold air will blow directly onto their body, reducing comfort.
[0004] To address this issue, a ceiling-mounted air conditioner with a liftable air outlet component has been developed. This ceiling-mounted air conditioner includes a main frame mounted on the ceiling and an air outlet component. The air outlet component is mounted on the main frame via a lifting mechanism. When the air conditioner is discharging air, the air outlet component descends relative to the main frame under the action of the lifting mechanism. After the air outlet component descends, its outer edge and the inner edge of the main frame form a horizontal air outlet, allowing the air to blow horizontally and achieve waterfall-style cooling, thus improving user comfort.
[0005] Since the air outlet component is a height-adjustable structure, the air duct structure changes during the lifting and lowering process, and many irregular structures are added inside the air duct, which can easily cause energy loss in the air outlet. Therefore, how to avoid energy loss in the air outlet within the air duct is an urgent problem to be solved in this technical field. Summary of the Invention
[0006] This invention discloses a ceiling fan that solves the problem that the air duct of existing ceiling fans has many irregular structures, which easily cause energy loss during air output.
[0007] To address the aforementioned problems, this invention discloses a ceiling fan, comprising a main frame, an air outlet assembly, and a lifting mechanism. An air outlet duct is formed within the main frame. The air outlet assembly is connected to the main frame via the lifting mechanism. The air outlet assembly forms a first air outlet between itself and the main frame as it descends. The main frame has a first windbreak located between the air outlet duct and the return air inlet. The air outlet assembly has a second windbreak located between the air outlet duct and the return air inlet. When the air outlet assembly descends to its working position, the first and second windbreaks cooperate to isolate the return air inlet from the first air outlet. The ceiling fan further includes a guide plate located within the air outlet duct. A first end of the guide plate is swayably mounted on the main frame. When the air outlet assembly descends to its working position, a second end of the guide plate overlaps the second windbreak. The guide plate covers at least a portion of the surface structure of the first and second windbreaks, and is used to guide the air outlet towards the first air outlet.
[0008] Furthermore, the air outlet assembly causes the air guide plate to swing by raising and lowering; during the descent of the air outlet assembly, the second end of the air guide plate descends by gravity and rests on the air outlet assembly; during the ascent of the air outlet assembly, the air outlet assembly pushes the air guide plate upward.
[0009] Furthermore, the second windbreak is provided with a first air guide surface, which is located on the side of the second windbreak facing the first air outlet, and the second end of the air guide plate can overlap on the first air guide surface.
[0010] Furthermore, the windward surface of the air guide plate forms a second air guide surface; when the air outlet assembly descends to the working position, the second air guide surface connects with the first air guide surface to form an air guide structure.
[0011] Furthermore, when the air outlet assembly rises to the retracted position, the air guide plate is in the avoidance position, and the air guide plate swings upward to avoid the retracted air outlet assembly.
[0012] Furthermore, a heat insulation layer is provided on the first windbreak and / or the second windbreak.
[0013] Furthermore, the air outlet assembly includes an air outlet frame, and the first air outlet is formed between the air outlet frame and the main frame. The air outlet frame can be raised and lowered independently.
[0014] Furthermore, the air outlet assembly includes an air outlet frame and a return air panel. The air outlet frame forms the first air outlet between itself and the main frame. The return air panel is provided with a return air outlet. The air outlet frame and the return air panel are connected and move up and down together.
[0015] Furthermore, the air outlet assembly is provided with at least one second air outlet, which is connected to the air outlet duct; when the air outlet assembly descends to the working position, the first wind baffle and the second wind baffle cooperate to isolate the airflow between the return air port and the first air outlet, and between the return air port and the second air outlet; when the air outlet assembly descends to the working position, the air guide plate is used to guide the air outlet to the first air outlet and / or the second air outlet.
[0016] Furthermore, when the air outlet component forms the first air outlet by descending and being positioned between itself and the main frame, a gap is formed between the air outlet component and the main frame, and the gap forms an air supply duct. One end of the air supply duct is connected to the air outlet duct, and the other end of the air supply duct forms the first air outlet.
[0017] Furthermore, the main frame also includes a frame. When the air outlet component descends to form the first air outlet between itself and the main frame, the air outlet component and the frame form the air supply duct. On the mounting plane of the main frame, the projection of the air outlet component and the projection of the frame at least partially overlap.
[0018] Furthermore, the hoist has a first air outlet mode, a second air outlet mode, and a third air outlet mode; when the hoist is in the first air outlet mode, the first air outlet is open and the second air outlet is closed; when the hoist is in the second air outlet mode, the first air outlet is open and some or all of the second air outlets are open; when the hoist is in the third air outlet mode, the first air outlet is closed and some or all of the second air outlets are open.
[0019] Furthermore, when the ceiling fan is in cooling mode, the ceiling fan is in either the first air outlet mode or the second air outlet mode;
[0020] When the ceiling fan is in heating mode, the ceiling fan is in either the third air outlet mode or the second air outlet mode.
[0021] The ceiling fan of the present invention oscillates one end of a guide plate on the main frame. When the air outlet assembly descends to the working position, the guide plate oscillates so that the other end overlaps the second windbreak and covers at least part of the surface structure of the first windbreak and at least part of the surface structure of the second windbreak. In other words, by blocking the irregular structure inside the air duct by the guide plate, not only can the air outlet be prevented from flowing through the irregular structure, thereby avoiding the generation of turbulence, but the air outlet in the air duct can also be guided to the air outlet by the guide plate, thereby increasing the air outlet efficiency and reducing air volume loss.

[0027] The present invention will be further described below with reference to embodiments, but is not limited to the contents of the specification.
[0028] like Figure 1 and Figure 2 The first embodiment of the present invention, as shown, discloses a ceiling fan, including a main frame 10, an air outlet assembly 20, a lifting mechanism, and an air guide plate 40. An air outlet duct 14 is formed within the main frame 10. The air outlet assembly 20 is connected to the main frame 10 via the lifting mechanism. The air outlet assembly 20 forms a first air outlet 31 between itself and the main frame 10 as it descends. The main frame 10 has a first windbreak portion 11 located between the air outlet duct 14 and the return air inlet. The air outlet assembly 20 has a second windbreak portion 21 located between the air outlet duct 14 and the return air inlet. Between the air outlets, when the air outlet assembly 20 descends to the working position, the first wind deflector 11 and the second wind deflector 21 cooperate to isolate the return air outlet and the first air outlet 31; the air guide plate 40 is located inside the air outlet duct 14, and the first end of the air guide plate 40 is swayably mounted on the main frame 10. When the air outlet assembly 20 descends to the working position, the second end of the air guide plate 40 overlaps the second wind deflector 21. The air guide plate 40 covers at least a portion of the surface structure of the first wind deflector 11 and at least a portion of the surface structure of the second wind deflector 21. The air guide plate 40 is used to guide the air outlet to the first air outlet 31.
[0029] The ceiling fan of the present invention has one end of the air guide plate 40 swayably mounted on the main frame 10. When the air outlet assembly 20 first descends to the working position, the air guide plate 40 swings so that the other end overlaps the second wind baffle 21 and covers at least part of the surface structure of the first wind baffle 11 and at least part of the surface structure of the second wind baffle 21. In other words, by blocking the irregular structure inside the air duct by the air guide plate 40, not only can the air outlet be prevented from flowing through the irregular structure, thereby avoiding the generation of turbulence, but the air outlet in the air duct can also be guided to the first air outlet 31 by the air guide plate 40, thereby making the air outlet efficiency higher and reducing the air volume loss.
[0030] It should be noted that the air guide plate 40 covering at least a portion of the surface structure of the first windbreak 11 and at least a portion of the surface structure of the second windbreak 21 refers to the space in which the first windbreak 11 and the second windbreak 21 cooperate to separate the return air inlet and the first air outlet 31. When the air outlet assembly 20 descends to the working position, this space will form a groove structure (e.g., C-shaped, L-shaped, inverted T-shaped). After the airflow passes through the groove structure, vortices will be generated, resulting in air volume loss. When the air outlet assembly 20 descends to the working position, the air guide plate 40 is located at the opening position of the first windbreak 11. The air guide plate 40 blocks the groove structure at the opening position, thereby avoiding the generation of vortices and reducing the air volume loss of the air outlet.
[0031] It should be noted that the main frame 10 is the primary load-bearing structure of the joist unit. During installation, the main frame 10 is mounted on the ceiling. Other structures can be directly or indirectly mounted on the main frame 10 and fixed to the ceiling via the main frame 10. The joist unit has an indoor unit installed within the ceiling. The main frame 10 is connected to the indoor unit, and the air outlet assembly 20 is connected to the main frame 10. The indoor unit has an exhaust vent, and the air outlet duct 14 of the main frame 10 is connected to the indoor unit's exhaust vent. The airflow path is: return air inlet - evaporator - indoor unit exhaust vent - air outlet duct 14 - air blown out from the exhaust vent.
[0032] Furthermore, one end of the air guide plate 40 is provided with a rotating shaft, and the air guide plate 40 is installed on the top of the first windproof part 11 through the rotating shaft. The air guide plate 40 can swing around the rotating shaft. The second end of the air guide plate 40 extends to the bottom of the first windproof part 11.
[0033] The air outlet assembly 20 causes the air guide plate 40 to swing through its lifting mechanism. When the ceiling fan is turned on, the air outlet assembly 20 descends, and the second end of the air guide plate 40 descends by gravity and overlaps the air outlet assembly 20. During the ascent of the air outlet assembly 20, it pushes the air guide plate 40 upward. The air outlet assembly 20's lifting mechanism causes the air guide plate 40 to swing, creating a linkage between the air outlet assembly 20 and the air guide plate 40. During descent, the air guide plate 40 automatically swings to a position that covers the first wind deflector 11 and the second wind deflector 21, and automatically retracts during ascent, avoiding manual adjustment, simplifying operation, and improving user experience.
[0034] The second windbreak 21 is provided with a first air guide surface 211, which is located on the side of the second windbreak 21 facing the first air outlet 31. The second end of the air guide plate 40 can overlap the first air guide surface 211. By providing the first air guide surface 211 on the second windbreak 21, the airflow can be guided to the first air outlet 31, reducing air volume loss and improving the air delivery effect.
[0035] The windward surface of the air guide plate 40 forms a second air guide surface 41. When the air outlet assembly 20 descends to the working position, the second air guide surface 41 connects with the first air guide surface 211 to form an air guide structure. By connecting the first air guide surface 211 and the second air guide surface 41 to form an air guide structure, the air originally blown towards the first wind deflector 11 and the second wind deflector 21 can be guided to the first air outlet 31. This not only avoids the generation of eddies but also makes the airflow path smoother, significantly reducing air volume loss and improving the air outlet effect.
[0036] like Figure 2 As shown, when the auger is closed, the air outlet assembly 20 rises to the retracted position, and the air guide plate 40 is in a clearance position. The air guide plate 40 swings upward to avoid the retracted air outlet assembly 20. By setting the clearance position, interference between the air outlet assembly 20 and the air guide plate 40 can be avoided when the auger is retracted, preventing damage to both and improving the reliability of the auger.
[0037] Furthermore, an insulation layer is provided on the first windbreak 11 and / or the second windbreak 21. By providing an insulation layer, the loss of cold air can be effectively prevented, the air supply effect can be improved, and condensation can also be prevented.
[0038] It should be noted that in this embodiment, the air outlet assembly 20 includes an air outlet frame, and a first air outlet 31 is formed between the air outlet frame and the main frame 10. The air outlet frame can be raised and lowered independently.
[0039] In another embodiment not shown, the air outlet assembly 20 includes an air outlet frame and a return air panel. A first air outlet 31 is formed between the air outlet frame and the main frame 10. The return air panel is provided with a return air outlet. The air outlet frame and the return air panel are connected and rise and fall together.
[0040] It should be noted that the lifting mechanism includes a transmission mechanism and a drive device. The transmission mechanism is connected between the main frame 10 and the air outlet assembly 20, and the drive device is driven by the transmission mechanism, thereby driving the transmission mechanism to lift the air outlet assembly 20. There can be multiple transmission mechanisms; in this embodiment, there are four transmission mechanisms, located at the four corners of the ceiling machine to ensure uniform force distribution. Preferably, the transmission mechanism can employ a belt drive structure, a rack and pinion drive structure, or a guide rail structure.
[0041] It should also be noted that in this embodiment, the driving device is a single motor, and each motor drives one transmission mechanism. However, the coordination between the motor and the transmission mechanism is not limited to this. In another embodiment (not shown in the figure), the other structures are the same as in this embodiment, except that one motor drives two transmission mechanisms, thereby reducing the number of motors and lowering costs. Similarly, one motor can also drive four lifting transmission mechanisms simultaneously, thereby further saving manufacturing costs.
[0042] according to Figure 3 and Figure 4 The second embodiment disclosed is a ceiling fan, whose structure is basically the same as that of the first embodiment, except that the air outlet assembly 20 is provided with at least one second air outlet 32, which is connected to the air outlet duct 14. When the air outlet assembly 20 is lowered to the working position, the first wind baffle 11 and the second wind baffle 21 cooperate to isolate the airflow between the return air port and the first air outlet 31, and between the return air port and the second air outlet 32. The ceiling fan also includes a guide plate 40, which is located in the air outlet duct 14 of the ceiling fan. The first end of the guide plate 40 is swayably set on the main frame 10. When the air outlet assembly 20 is lowered to the working position, the second end of the guide plate 40 overlaps the second wind baffle 21. The guide plate 40 covers at least part of the surface structure of the first wind baffle 11 and at least part of the surface structure of the second wind baffle 21. The guide plate 40 is used to guide the air outlet to the first air outlet 31 and / or the second air outlet 32.
[0043] The ceiling fan of the present invention has one end of the air guide plate 40 swayably mounted on the main frame 10. When the air outlet assembly 20 first descends to the working position, the air guide plate 40 swings so that the other end overlaps the second wind baffle 21 and covers at least part of the surface structure of the first wind baffle 11 and at least part of the surface structure of the second wind baffle 21. In other words, by blocking the irregular structure inside the air duct by the air guide plate 40, not only can the air outlet be prevented from flowing through the irregular structure, thereby avoiding the generation of turbulence, but the air outlet in the air duct can also be guided to the first air outlet 31 by the air guide plate 40, thereby making the air outlet efficiency higher and reducing the air volume loss.
[0044] The first air outlet 31 allows the ceiling fan to direct airflow to a distance, even horizontally or at an angle upwards, overcoming the problem of cold air blowing downwards and directly onto the human body in existing technologies. Simultaneously, the second air outlet 32 enables the ceiling fan to meet the requirements of angled downwards or even vertical downwards. Furthermore, the combination of the first and second air outlets 31 increases the number of air outlet methods available for the ceiling fan, thereby improving its airflow effect and enhancing the precision and speed of temperature regulation.
[0045] It should be noted that the main frame 10 is the main load-bearing structure of the ceiling hoist. During the installation of the ceiling hoist, the main frame 10 is used to install it on the ceiling. Other structures can be directly or indirectly installed on the main frame 10 and fixed to the ceiling through the main frame 10.
[0046] When the air outlet assembly 20 descends and forms the first air outlet 31 between itself and the main frame 10, a gap is formed between the air outlet assembly 20 and the main frame 10, forming an air supply duct 12. One end of the air supply duct 12 is connected to the air outlet duct 14, and the other end of the air supply duct 12 forms the first air outlet 31. The airflow in the air outlet duct 14 is guided by the air supply duct 12 and then blown out through the first air outlet 31. The air supply duct 12 guides the vertically downward airflow in the air outlet duct 14 into a direction that is roughly horizontal and away from the ceiling machine, or even tilted upward relative to the horizontal plane, thereby achieving horizontal airflow to the ceiling machine.
[0047] In the prior art, ceiling fans all use vents on the surface facing the ground to deliver air. To change the direction of the airflow, a guide vane is installed at the vent. However, on the mounting plane of the ceiling fan, the projection of the guide vane does not coincide with the projection of the ceiling fan panel, resulting in poor airflow guidance and ultimately reducing the air delivery distance of the ceiling fan. To address this, the main frame 10 of this application also includes a frame 13. When the air outlet component 20 descends to form the first air outlet 31 between itself and the main frame 10, the air outlet component 20 and the frame 13 form the air delivery duct 12. On the mounting plane of the main frame 10 (such as the ceiling), the projection of the air outlet component 20 and the projection of the frame 13 at least partially coincide. When the projection of the air outlet component 20 coincides with the projection of the frame 13, it effectively extends the air outlet component 20 compared to the prior art, resulting in better horizontal blowing effect of the ceiling fan and increased air delivery distance. When the ceiling fan opens the first air outlet 31, the air outlet component 20 gradually moves away from the main frame 10 to form the air delivery duct 12. At this time, the corresponding part of the air outlet component 20 forms the lower side of the air delivery duct 12. When the airflow passes through the air delivery duct 12, the airflow flows horizontally or even blows out in an upward tilting direction under the guiding effect of the lower side of the air delivery duct, thereby increasing the air delivery distance of the ceiling fan and achieving the effect of horizontal air outlet.
[0048] In another implementation, the projection of the air outlet assembly 20 completely overlaps with the projection of the frame 13. In this case, compared to the case where the projection of the air outlet assembly 20 partially overlaps with the projection of the frame 13, the air outlet assembly can be further extended, thereby improving the flat blowing effect of the auger and further increasing the air delivery distance. Simultaneously, when the auger is in the off state, the air outlet assembly 20 is attached to the main frame 10, and the corresponding part of the air outlet assembly 20 is attached to the frame 13. When personnel observe the auger from the ground, they can only see the air outlet assembly 20 and not the main frame 10, effectively increasing the aesthetics of the auger.
[0049] It should be noted that the ceiling fan has a first air outlet mode, a second air outlet mode, and a third air outlet mode:
[0050] When the well rig is in the first air outlet mode, the first air outlet 31 is opened and the second air outlet 32 is closed. At this time, all the airflow in the air outlet duct 14 is blown out through the first air outlet 31, which forms a horizontal air outlet or even an upward tilted air outlet.
[0051] When the well machine is in the second air outlet mode, the first air outlet 31 and the second air outlet 32 are opened. At this time, part of the airflow in the air outlet duct 14 is blown out through the first air outlet 31, and the remaining part is blown out through the second air outlet 32, so as to achieve circumferential air supply and improve the uniformity of room temperature.
[0052] When the well rig is in the third air outlet mode, the first air outlet 31 is closed and the second air outlet 32 is opened. At this time, all the airflow in the air outlet duct 14 is blown out through the second air outlet 32, which forms a downward air outlet or even a vertical downward air outlet.
[0053] Based on the aforementioned air outlet patterns, the joist re-plans its heating and cooling modes. When the joist is in cooling mode, it operates in either the first or second air outlet mode. When the joist is in heating mode, it operates in either the third or second air outlet mode.
[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all embodiments here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
