Description

Technical Field

[0001] This utility model specifically relates to the field of air conditioning equipment technology, and more specifically to a blower structure. Background Technology

[0002] In the structure of a wall-mounted air conditioner, the blower unit is a key component for achieving air circulation and cooling or heating effects. Its performance directly affects the air conditioner's operating efficiency, noise level, and lifespan. Current technology for blower structures in wall-mounted air conditioners typically suffers from the following problems: some impellers are made of plastic, which, while lightweight, has poor durability and is prone to blade deformation and breakage after prolonged use; it also lacks fire resistance. Furthermore, the manufacturing process for the blower is complex, often employing modular assembly or multiple processing steps, resulting in low production efficiency and high production costs, making it difficult to meet the demands of large-scale industrial production. Therefore, improvements to the existing blower structure are needed to enhance its durability, reduce production costs, and increase production efficiency. The traditional fan blades inside the blower can easily cause air turbulence when they rotate, which prevents the air from circulating effectively and regularly during cooling or heating. The airflow also rubs and impacts solid surfaces, generating high-frequency or low-frequency noise. This turbulence noise is more noticeable, especially at night in low-speed mode, and can disrupt rest. Utility Model Content

[0003] The purpose of this invention is to provide a blower structure in which turbulence grooves with equal spacing are provided on the edge of the impeller. This effectively avoids noise generation when the air conditioner is working. When the impeller rotates through the rotating disk, one end of the rotating disk is engaged with a wear-resistant bushing through a rotating shaft, and the other end is fixed to the reducer shaft. The wear-resistant bushing effectively prevents abnormal noise caused by friction between the rotating shaft and the reducer shaft when the impeller rotates, thus solving the problems mentioned above in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A blower structure includes an integrally injection-molded blower; two limit posts and positioning posts are respectively provided on the top of the blower; the tops of the limit posts and positioning posts are flush; through grooves are provided on the side walls of both sides of the blower to facilitate the installation of wear-resistant bushings; a blower wheel is movably installed inside the blower; multiple blowers are provided; the two ends of the multiple blowers are fixedly installed to a rotating disk; and turbulence grooves are provided on the edge of each blower wheel.

[0005] As a further technical solution of this utility model, one end of the rotating disk is movably installed with a wear-resistant bushing via a rotating shaft; the other end of the rotating disk is fixedly installed with the rotating shaft of the reducer; the reducer is fixedly installed at one end of the blower via bolts and connecting columns.

[0006] As a further technical solution of this utility model, the air inlet of the blower is detachably equipped with a protective net; and an installation groove is provided on the bottom side of the blower to facilitate the installation of the guide plate.

[0007] As a further technical solution of this utility model, the inner surface of the guide plate is arc-shaped; the top of the guide plate is integrally provided with multiple insertion posts; the insertion posts are inserted and fixed with the round holes opened on the blower.

[0008] As a further technical solution of this utility model, a uniform gap is reserved between the outer edge of the rotating disk and the impeller and the inner surface of the blower and the guide plate.

[0009] As a further technical solution of this utility model, the wind turbine has a diameter of 50mm and a length of 145mm; the wind turbine is made of aluminum material.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the impeller is made of aluminum material. Aluminum material is durable, has good fire resistance and is lightweight, which effectively improves the service life and safety of the impeller. It can adapt to the working environment of long-term operation of air conditioner. Furthermore, turbulence grooves are opened on the impeller to ensure air stability and avoid noise caused by collision between air and the air conditioner casing. 2. In this utility model, the protective net installed on the top of the blower can effectively filter external impurities, preventing them from entering the blower and affecting the working efficiency of the impeller. The protective net is detachable, making it easier to clean and maintain compared to the traditional integrated protective net. 3. In this utility model, when installing the blower, the limiting posts and positioning posts at both ends of the top effectively ensure the coaxiality of the two ends of the blower, avoiding the blower from tilting during installation, thereby effectively ensuring the working efficiency of the air conditioner; 4. This utility model effectively ensures that the air generated by the impeller during rotation is evenly discharged from the air outlet of the impeller by installing a guide plate at the bottom of the blower.

During the installation of the blower 2, the limiting post 3 and the positioning post 4 effectively ensure the coaxiality of the two ends of the blower 2, thereby ensuring the accuracy of the installation of the blower wheel 5 and preventing the blower wheel 5 from tilting.

[0021] One end of the rotating disk 9 is movably installed with the wear-resistant bushing 8 via a rotating shaft; the other end of the rotating disk 9 is fixedly installed with the rotating shaft of the reducer 1; the reducer 1 is fixedly installed at one end of the blower 2 by bolts and connecting column 12. The wear-resistant bushing 8 effectively reduces the wear of the rotating shaft and the output shaft of the reducer 1, ensuring the stability of the impeller 5.

[0022] By adopting the above technical solution, the impeller 5 is made of aluminum material. Aluminum material is durable, has good fire resistance and is lightweight, which effectively improves the service life and safety of the impeller and can adapt to the working environment of long-term operation of air conditioner. Furthermore, a turbulence groove 10 is provided on the impeller 5 to ensure air stability and avoid noise caused by collision between the air and the air conditioner casing.

[0023] In this embodiment, the air inlet of the blower 2 is detachably equipped with a protective net 6; a mounting groove 11 is provided on the bottom side of the blower 2 to facilitate the installation of the guide plate 7; the protective net 6 effectively filters external impurities, preventing them from entering the blower and contacting the impeller 5, thus affecting the working efficiency of the impeller 5; the protective net 6 is easy to disassemble, allowing for separate cleaning or maintenance of the protective net 6. In this embodiment, the inner surface of the guide plate 7 is arc-shaped; the top of the guide plate 7 is integrally provided with multiple insertion posts 13; the insertion posts 13 are inserted and fixed with the round holes opened on the blower 2; the inner walls of the guide plate 7 and the blower 2 effectively form a stable airflow generated by the impeller 5. By adopting the above technical solution, the protective net 6 installed on the top of the blower 2 can effectively filter external impurities, preventing impurities from entering the interior of the blower 2 and affecting the working efficiency of the impeller 5. The protective net 6 can be disassembled, making it easier to clean and maintain compared to the traditional integrated protective net.

[0024] Furthermore, during the installation of the blower 2, the limiting posts 3 and positioning posts 4 at both ends of the top effectively ensure the coaxiality of the two ends of the blower 2, preventing the blower 2 from tilting during installation, thereby effectively ensuring the working efficiency of the air conditioner. In this embodiment, a uniform gap is reserved between the outer edge of the rotating disk 9 and the impeller 5 and the inner surface of the blower 2 and the guide plate 7; this avoids friction between the impeller 5 and the surface of the blower 2 or the guide plate 7 when the impeller 5 rotates, thus preventing noise generation. The wind turbine 5 has a diameter of 50mm and a length of 145mm; the wind turbine 5 is made of aluminum; the aluminum material effectively improves the practicality of the wind turbine 5. By adopting the above technical solution, the guide plate 7 installed at the bottom of the blower 2 effectively ensures that the wind generated by the impeller 5 during rotation is evenly discharged from the air outlet of the blower 2.

The output shaft is engaged with a groove on the side wall of one end of the blower 2 via the wear-resistant bushing 8. The wear-resistant bushing 8 effectively reduces the wear on the rotating shaft. When the reducer 1 drives the impeller 5 to rotate, the wind generated by the impeller 5 forms a stable airflow through the inner wall of the blower 2 and the guide plate 7. The turbulence groove 10 opened on the impeller 5 further ensures the stability of the airflow. The impeller 5 is made of aluminum, which ensures the durability and stability of the impeller 5 and avoids damage during long-term use.
