Abstract
Description
Technical Field
[0001] This invention relates to the field of air handling equipment technology, and in particular to a ceiling air handling unit with an extension mechanism. Background Technology
[0002] A ceiling-mounted air conditioner is a type of air conditioner that is recessed into the ceiling to reduce space usage. It exchanges heat through air outlets on its surface. Due to the limited location of these outlets, it can only blow air in a set direction and cannot provide horizontal airflow when cooling. This is particularly problematic in commercial and industrial settings, where the downward airflow can cause discomfort and, with prolonged exposure, can lead to colds and other illnesses. Summary of the Invention
[0003] In order to solve the technical problem that the downward airflow of the existing ceiling fan causes discomfort, a ceiling fan with an extension mechanism is provided to increase the horizontal air outlet distance.
[0004] A ceiling hoist with an extension mechanism includes:
[0005] Main framework;
[0006] An air outlet assembly, wherein a first air outlet is formed between the air outlet assembly and the main frame;
[0007] An extension mechanism is provided on the air outlet assembly, and the airflow from the first air outlet flows horizontally out after passing through the extension mechanism from above;
[0008] The extension mechanism is capable of moving in a direction away from or towards the main frame.
[0009] An air supply duct is formed between the main frame and the air outlet assembly. One end of the air supply duct forms the first air outlet. The extension mechanism constitutes part of the lower side of the air supply duct. The extension mechanism can increase the length of the lower side of the air supply duct when moving away from the main frame or decrease the length of the lower side of the air supply duct when moving closer to the main frame.
[0010] The extension mechanism includes:
[0011] A drive mechanism, which is disposed on the air outlet assembly or the main frame;
[0012] An extension plate is connected to the drive mechanism, and the drive mechanism is capable of moving the extension plate in a direction away from or towards the main frame.
[0013] The driving mechanism includes a driving member and a rack, the extension plate is connected to the rack, and the driving member meshes with the rack.
[0014] The drive mechanism also includes a guide rail, and the extension plate is movably mounted on the guide rail.
[0015] The air outlet assembly is provided with a second air outlet, and the airflow of the ceiling machine flows through the second air outlet and the extension mechanism in sequence.
[0016] The ceiling machine also includes an air guide plate, which is rotatably disposed at the second air outlet.
[0017] The air outlet assembly can be lowered relative to the main frame to form the first air outlet, and the extension mechanism is disposed on the air outlet assembly.
[0018] The air outlet assembly includes an air outlet frame, which can be raised and lowered independently, and the extension mechanism is disposed on the air outlet frame.
[0019] The air outlet assembly includes an air outlet frame and a return air panel. The return air panel is provided with a return air inlet. The air outlet frame is connected to the return air panel and moves up and down together. The extension mechanism is provided on the air outlet frame.
[0020] The ceiling fan with an extension mechanism provided by this invention increases the guidance of airflow by increasing the length of the lower side of the air supply duct, so that the air outlet of the first outlet is far away from the main frame. This effectively overcomes the problem of the existing technology that can only produce downward airflow and cause people to be blown away, and achieves "waterfall-style" cooling. At the same time, in order to ensure the air outlet effect, a second air outlet for downward air outlet is also provided, so that the ceiling fan can simultaneously meet the downward air outlet requirement of the existing technology. By opening and closing the first air outlet and the second air outlet, the air outlet mode of the ceiling fan is increased, and the air outlet effect of the ceiling fan is further improved.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.
[0027] like Figure 1 The ceiling fan with an extension mechanism shown includes: a main frame 1; an air outlet assembly 2, forming a first air outlet 10 between the air outlet assembly 2 and the main frame 1; and an extension mechanism 3, which is disposed on the air outlet assembly 2, and the airflow from the first air outlet 10 flows horizontally after passing over the extension mechanism 3; the extension mechanism 3 can move in a direction away from or towards the main frame 1. Compared to ceiling fans without an extension mechanism 3, the horizontal flow distance of the airflow from the first air outlet 10 is increased, that is, due to the guiding effect of the extension mechanism 3, the airflow from the first air outlet 10 can flow further away from the main frame 1, thereby effectively increasing the air delivery distance and avoiding the problem of blowing air into people caused by only producing downward airflow in the prior art, ultimately achieving a "waterfall-like" cooling effect.
[0028] An air supply duct 11 is formed between the main frame 1 and the air outlet assembly 2. One end of the air supply duct 11 forms the first air outlet 10. The extension mechanism 3 constitutes part of the lower side of the air supply duct 11. The extension mechanism 3 can increase the length of the lower side of the air supply duct 11 when moving away from the main frame 1, or decrease the length of the lower side of the air supply duct 11 when moving closer to the main frame 1. When the extension mechanism 3 moves away from the main frame 1, it increases the length of the lower side of the air supply duct 11, thereby increasing the flow distance of the airflow on the lower side of the air supply duct 11 and restricting the downward flow of the airflow. This effectively increases the horizontal flow distance of the airflow at the first air outlet 10 of the ceiling fan, achieving the purpose of increasing the air supply distance. Moreover, when the extension mechanism 3 moves closer to the main frame 1, it is retracted, which avoids the extension mechanism 3 from affecting the aesthetics of the ceiling fan and also prevents the extension mechanism 3 or its related structures from being constantly exposed to the outside, thus avoiding damage.
[0029] Specifically, an air outlet duct is provided inside the main frame 1. One end of the air supply duct 11 is connected to the air outlet duct, and the other end of the air supply duct 11 forms the first air outlet 10. The airflow in the air outlet duct can flow through the air supply duct 11 to the first air outlet and finally blow out of the ceiling machine.
[0030] Specifically, the extension mechanism 3 includes: a drive mechanism disposed on the air outlet assembly 2 or the main frame 1; and an extension plate 31 connected to the drive mechanism, which can drive the extension plate 31 to move in a direction away from or towards the main frame 1. The drive mechanism controls the movement of the extension plate 31, which can guide the airflow passing above it, preventing the airflow from flowing downwards due to gravity.
[0031] The driving mechanism includes a driving component 32 and a rack 33. The driving component 32 is disposed on the air outlet assembly 2 or the main frame 1. The extension plate 31 is connected to the rack 33, and the driving component 32 and the rack 33 mesh with each other. The driving component 32 is provided with an output gear, which meshes with the rack 33 to realize the movement of the extension plate 31.
[0032] Preferably, the driving component 32 is a stepper motor.
[0033] The drive mechanism also includes a guide rail 34, which is disposed on the air outlet assembly 2 or the main frame 1, and the extension plate 31 is movably disposed on the guide rail 34. The guide rail 34 can restrict the extension plate 31 to move in a set direction, avoiding interference between the extension plate 31 and other structures that would affect the reliability of the ceiling fan.
[0034] The air outlet assembly 2 is provided with a second air outlet 12, and the airflow of the ceiling fan flows sequentially through the second air outlet 12 and the extension mechanism 3. That is, the extension mechanism 3 does not affect the airflow from the second air outlet 12, which enables the ceiling fan to meet the requirements of downward or even vertical downward airflow. Furthermore, the cooperation between the first air outlet 10 and the second air outlet 12 increases the number of airflow methods for the ceiling fan, thereby increasing its airflow effect and the accuracy and speed of temperature regulation.
[0035] It should be noted that the main frame 1 is the primary load-bearing structure of the joist unit. During installation, the main frame 1 is used to mount the joist unit to the ceiling. Other structures can be directly or indirectly mounted on the main frame 1 and fixed to the ceiling via the main frame 1. The joist unit has an indoor unit installed inside the ceiling. The main frame 1 is connected to the indoor unit, and the air outlet assembly 2 is connected to the main frame 1. The indoor unit has an indoor unit exhaust vent. The first end of the air outlet duct of the main frame 1 is connected to the indoor unit exhaust vent. The airflow path is: return air inlet - evaporator - indoor unit exhaust vent - first end of air outlet duct - second end of air outlet duct - air outlet (first air outlet 10 and / or second air outlet 12) blown out.
[0036] The ceiling fan also includes an air guide plate 4, which is rotatably mounted at the second air outlet 12. The air guide plate 4 can close or open the second air outlet 12. When the second air outlet 12 needs to be opened, the air guide plate 4 gradually rotates, connecting the second air outlet 12 with the air outlet duct on the main frame 1, allowing airflow in the air outlet duct to be blown out through the second air outlet 12. The air guide plate 4 can adjust its tilt angle to adjust the airflow direction and / or airflow volume of the second air outlet 12 as needed. When the second air outlet 12 needs to be closed, the air guide plate 4 returns to a sealed position with the air outlet assembly 2, thereby closing the second air outlet 12. At this time, airflow in the air outlet duct cannot be discharged through the second air outlet 12.
[0037] The air outlet assembly 2 can descend relative to the main frame 1 to form the first air outlet 10, and the extension mechanism 3 is disposed on the air outlet assembly 2. After the air outlet assembly 2 descends, a gap is formed between it and the main frame 1, which forms an air supply duct 11. Simultaneously, to facilitate the arrangement of the extension mechanism 3, the extension mechanism 3 is disposed on the air outlet assembly 2 and rises and falls together with the air outlet assembly 2. When the ceiling fan is in a stopped state, the air outlet assembly 2 can rise and seal against the main frame 1, thereby preventing dust and impurities from entering the ceiling fan through the first air outlet 10 and causing a decrease in the reliability of the ceiling fan. At the same time, the rising air outlet assembly 2 increases the aesthetics of the ceiling fan. When the ceiling fan needs to operate, the air outlet assembly 2 can descend to form the first air outlet 10 for air outlet, achieving a waterfall-style cooling effect.
[0038] The air outlet assembly 2 includes an air outlet frame, which can be raised and lowered independently, and the extension mechanism 3 is disposed on the air outlet frame.
[0039] In other embodiments not shown, the air outlet assembly 2 includes an air outlet frame and a return air panel, the return air panel is provided with a return air inlet, the air outlet frame is connected to the return air panel and rises and falls together, and the extension mechanism 3 is disposed on the air outlet frame.
[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
