A ducted rotary ceiling machine

Abstract

This utility model provides a duct-driven rotating ceiling air conditioner, comprising a housing, mounting blocks, and an automatic rotating duct. By installing mounting blocks and their corresponding angle adjustment structures on both sides of the housing, the entire housing can rotate within a certain range during installation. This allows for large-angle adjustment of the airflow direction to suit different installation environments and usage requirements, improving the equipment's spatial adaptability. Compared to traditional methods that rely solely on guide vanes for fine-tuning, housing rotation allows for a greater range of airflow direction adjustments, making it particularly suitable for scenarios with varying ceiling heights and complex interior layouts, enhancing the directionality and effectiveness of airflow. Furthermore, the automatic rotating duct inside the housing employs a rotatable structure, enabling independent angle rotation from the pre-adjusted housing angle to adjust the airflow angle. This not only improves airflow efficiency but also allows for adjustment of the airflow angle according to environmental changes or user needs.

Description

Technical Field

[0001] This utility model relates to the field of ceiling machine technology, specifically a duct-type rotary ceiling machine. Background Technology

[0002] Ceiling fans are air delivery devices installed on the ceiling, widely used in various indoor spaces such as office buildings, shopping malls, and residences. Their main function is to circulate and regulate indoor air to improve air quality and living comfort. Existing ceiling fans adjust the airflow direction and angle by swinging a guide vane. However, these guide vanes have several drawbacks. In practical applications, the swing angle of traditional guide vanes is limited, failing to achieve wide-area airflow coverage, especially in large spaces where they struggle to meet the needs of multi-zone airflow, leading to uneven airflow and uneven temperature distribution. Furthermore, because the guide vane has a sheet-like structure, its airflow adjustment method is relatively simple, only allowing up-and-down swinging. Therefore, at certain installation angles or locations, it cannot meet users' personalized needs for airflow angle or intensity. Thus, it is necessary to develop a ceiling fan with a wide adjustable airflow angle and the ability to adjust the entire unit. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a duct-type rotating ceiling air conditioner, which effectively improves some of the problems of traditional ceiling air conditioners, such as small air supply angle adjustment range, single air guiding method, and poor air supply comfort.

One side of the housing along its length is open, and a panel is provided at the opening. The panel has inlet and outlet air grilles. The mounting blocks are fixed to both sides of the housing along its length and have angle adjustment structures. The automatically rotating air duct is disposed inside the housing and includes a rotatable duct and a fan. The rotatable duct is an open duct along its length and is rotatably disposed within the housing. The fan is rotatably disposed within the rotatable duct.

The end of the second bearing seat away from the rotatable air duct is provided with another bearing, and the end of this bearing away from the rotatable air duct is rotatably connected to another motor frame. The motor frame closer to the second bearing seat is disposed on the right mounting plate.

[0006] Furthermore, a motor is mounted on the right mounting plate of the air duct, and the output end of the motor is connected to the side of the impeller near the right mounting plate of the air duct.

[0007] Furthermore, it also includes an air duct reinforcing plate, on which the left air duct fixing plate and the right air duct mounting plate are connected and disposed, and the air duct reinforcing plate is connected to the housing.

[0008] Preferably, the impeller is provided with a rotating shaft on the side near the left fixed plate of the air duct, and the rotatable air duct is provided with a through hole on the side near the left fixed plate of the air duct.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a duct-type rotating ceiling air conditioner, comprising a housing, mounting blocks, and an automatic rotating air duct. By setting mounting blocks and their matching angle adjustment structures on both sides of the housing, the entire housing can rotate within a certain range during installation. This allows for large-angle adjustment of the airflow direction to suit different installation environments and usage requirements, improving the equipment's spatial adaptability. Compared to traditional methods that rely solely on guide vanes for fine-tuning, housing rotation allows for a greater range of airflow direction adjustments, making it particularly suitable for scenarios with varying ceiling heights and complex interior layouts, enhancing the directionality and effectiveness of airflow. Furthermore, the automatic rotating air duct inside the housing employs a rotatable structure, enabling independent angle rotation from the already adjusted housing angle to adjust the airflow angle.

Detailed Implementation

[0017] The embodiments described below are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] See Figures 1-7 This embodiment provides a duct-type rotating ceiling air conditioner, which includes a housing 3, a mounting block 1, and an automatically rotating air duct. One side of the housing 3 along its length is open, and a panel is provided at the opening. The panel has an inlet / outlet grille 2. The mounting block 1 is fixed to both sides of the housing 3 along its length, and an angle adjustment structure is provided on the mounting block 1. The automatically rotating air duct is disposed inside the housing 3 and includes a rotatable air duct 8 and a fan wheel 5. The rotatable air duct 8 is an open air duct along its length and is rotatably disposed within the housing 3. The fan wheel 5 is rotatably disposed within the rotatable air duct 8.

[0019] Specifically, the automatic rotating air duct also includes a left fixed plate 4, a right mounting plate 7, a first bearing seat 9, a second bearing seat 12, a pair of bearings 10, and a pair of motor frames 11. The two motor frames 11 are respectively disposed on the outer sides of both ends of the rotatable air duct 8 in the length direction. One motor frame 11 is disposed on the rotatable air duct 8, and its end away from the rotatable air duct 8 is rotatably connected to a bearing 10, which is disposed on the first bearing seat 9. The first bearing seat 9 is mounted on the left fixed plate 4. The end of the rotatable air duct 8 away from the first bearing seat 9 is provided with the second bearing seat 12. The end of the second bearing seat 12 away from the rotatable air duct 8 is provided with another bearing 10, and the end of the bearing 10 away from the rotatable air duct 8 is rotatably connected to another motor frame 11. The motor frame 11 near the second bearing seat 12 is disposed on the right mounting plate 7.

[0020] See Figure 2 , Figure 3Specifically, in this application, the first bearing seat 9 is snapped onto the left fixing plate 4 of the air duct. The motor frame 11 on the side near the first bearing seat 9 is fixed to the side wall of the rotatable air duct 8 with ST4.2*10 self-tapping screws. The motor frame 11 on this side is rotatably connected to the bearing 10 disposed on the first bearing seat 9. Simultaneously, the second bearing seat 12 is fixed to the side wall of the rotatable air duct 8 with ST4.2*10 self-tapping screws. The motor frame 11 on the side near the second bearing seat 12 is fixed to the right mounting plate 7 of the air duct with ST4.2*10 self-tapping screws. The motor frame 11 on this side is rotatably connected to the bearing 10 disposed on the second bearing seat 12.

[0021] Furthermore, a motor 6 is mounted on the right mounting plate 7 of the air duct. The motor 6 is fixed to the right mounting plate 7 of the air duct by M4*10 screws and nuts. The output end of the motor 6 passes through the openings in the right mounting plate 7 of the air duct, the motor frame 11, the bearing 10, and the second bearing seat 12, and is connected to the impeller 5. Furthermore, the impeller 5 is a horizontally arranged cross-flow impeller 5 or a centrifugal impeller 5, which is driven to rotate by the output shaft of the motor 6 and is located inside the rotatable air duct 8 to transport air along the opening of the air duct.

[0022] See Figure 3 , Figure 6 , Figure 7Preferably, a synchronous motor assembly 13 is mounted on the side of the second bearing housing 12 near the rotatable air duct 8. A transmission mechanism 16 is connected to the output end of the synchronous motor assembly 13, and the transmission mechanism 16 is connected to the rotatable air duct 8. Specifically, in this application, the synchronous motor assembly 13 is fixed to the right mounting plate 7 of the air duct near the second bearing housing 12 using ST3.2*10 self-tapping screws. One end of the transmission mechanism 16 is connected to the output end of the synchronous motor assembly 13, and the output end of the transmission mechanism 16 is connected to the rotatable air duct 8. The transmission mechanism 16 includes a connecting rod 17 pivotally connected to the synchronous motor assembly 13. A screw is provided at the end of the connecting rod 17 away from the synchronous motor assembly 13, and an arc-shaped rod 18 is rotatably mounted on the screw. The end of the arc-shaped rod 18 away from the connecting rod 17 is rotatably connected to the rotatable air duct 8 via the screw. Through the cooperation of the synchronous motor assembly 13 and the transmission mechanism 16, reliable drive adjustment of the rotatable air duct 8 can be achieved. Specifically, when the synchronous motor assembly 13 operates, its output shaft drives the connecting rod 17 to rotate, and the screw at the distal end of the connecting rod 17 rotates accordingly, thereby causing the arc-shaped rod 18 mounted on the screw to deflect at an angle. Since the end of the arc-shaped rod 18 furthest from the connecting rod 17 forms a rotatable connection structure with the rotatable duct 8 through the screw, when the arc-shaped rod 18 rotates, it causes the rotatable duct 8 to adjust its angle around its axis. Therefore, it can adjust the orientation of the opening of the rotatable duct 8 along its length, thereby adjusting the air outlet angle.

[0023] See Figure 3 , Figure 4 Preferably, it also includes a duct reinforcing plate 15, on which the left duct fixing plate 4 and the right duct mounting plate 7 are connected and disposed, and the duct reinforcing plate 15 is connected to the housing 3. The duct reinforcing plate 15 thus fixes the entire automatic rotating duct within the housing 3.

[0024] See Figure 3 Preferably, the impeller 5 has a rotating shaft on the side near the left fixed plate 4 of the air duct, and the rotatable air duct 8 has a through hole on the side near the left fixed plate 4. The rotating shaft of the impeller 5 passes through the through hole and connects to the motor frame 11. This structure can provide radial support at the other end of the impeller 5 during the rotation driven by the motor 6, improving the balance and stability of the impeller 5 during rotation and avoiding problems such as shaking, jumping or abnormal noise during operation.

[0025] Preferably, the angle adjustment structure includes an arc-shaped groove and a locating pin slidably connected to the arc-shaped groove. Specifically, the arc-shaped groove is formed on one side of the connecting surface of the mounting block 1, and its groove body extends along an arc trajectory, with its center pointing to the rotation axis of the housing 3, facilitating angle adjustment around the mounting point. The locating pin is inserted into the arc-shaped groove, and the end of the locating pin is fixedly connected to the mounting block 1 by a threaded structure, or is provided with a knob handle for easy manual tightening or loosening. During adjustment, the locating pin can be loosened, allowing the housing 3 to rotate around the axis of the mounting block 1 along the arc-shaped groove trajectory. After adjusting to the target angle, the locating pin is tightened to lock the angle, ensuring stability and reliability during use, thereby achieving adjustment of the angle of the housing 3. The locating pin is used to connect with the mounting structure at the mounting position.

[0026] See Figure 5 Preferably, the openings on the air inlet / outlet grille 2 are teardrop-shaped, thus forming a flow-guiding structure with good airflow guiding effect. Furthermore, by adopting a teardrop-shaped opening design, compared to traditional round or rectangular hole structures, this application can effectively reduce airflow resistance when passing through the grille, reduce eddies and wind noise, and improve wind speed output efficiency and air intake efficiency; at the same time, the teardrop-shaped structure is more streamlined visually, which helps to improve the overall aesthetics and product quality. It should also be noted that in this application, the air inlet / outlet grille 2 is fixed to the housing 3 with ST4.2*10 self-tapping screws. One side of the air inlet / outlet grille 2 serves as an air inlet, and the other side serves as an air outlet, adjusting the air inlet / outlet position according to the orientation of the opening along the length of the rotatable air duct 8.

[0027] Preferably, it also includes a decorative panel 14, which is installed at the opening of the housing 3 on one side of the motor 6, making the product more aesthetically pleasing.

[0028] This utility model provides a duct-type rotating ceiling air conditioner, comprising a housing 3, mounting blocks 1, and an automatic rotating air duct. By setting mounting blocks 1 and their matching angle adjustment structures on both sides of the housing 3, the entire housing 3 can rotate within a certain range in the installed state. This allows for large-angle adjustment of the air outlet direction according to different installation environments and usage requirements, improving the spatial adaptability of the equipment. Compared with the traditional method of relying solely on guide vanes for fine-tuning the angle, the rotation of the housing 3 allows for a greater range of airflow direction adjustment, making it particularly suitable for scenarios with varying ceiling heights and complex interior layouts, enhancing the directionality and effectiveness of airflow. Furthermore, the automatic rotating air duct inside the housing 3 has a rotatable structure, enabling independent angle rotation based on the already adjusted angle of the housing 3, thus adjusting the air outlet angle. This not only improves airflow efficiency but also allows for adjustment of the airflow angle according to environmental changes or user needs. Therefore, this duct-type rotating ceiling air conditioner significantly expands the airflow range and the freedom of angle adjustment, significantly improving airflow coverage and comfort, and is suitable for various complex installation scenarios.

Therefore, any equivalent changes made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
