Description

Technical Field

[0001] The present invention relates to the technical field of automobile air-conditioning duct structure, and in particular to an automobile air-conditioning duct structure and an air-conditioning duct optimization design method. Background Art

[0002] The air duct system of automobile air conditioning is a key component of automobile air conditioning. It is responsible for delivering air from the air conditioning system into the car to ensure that the temperature and humidity of the air in the car reach a comfortable state. The design of the entire air duct system directly affects the cooling and heating effects of the air conditioner and the air circulation efficiency. The air duct is the channel responsible for transmitting air in the air conditioning system, usually made of plastic or soft materials (such as PVC, rubber, aluminum alloy, etc.). The structure of the automobile air conditioning duct system is complex and involves the collaboration of multiple components. The core components include air ducts (pipes), fans, air filters, evaporators, condensers, air outlets and regulating devices. Reasonable design and layout can effectively improve the working efficiency of the air conditioning system and ensure that car owners can enjoy a comfortable in-car environment under various climatic conditions.

[0003] The document with prior art publication number CN221188050U provides an automobile air-conditioning duct connection structure. By providing a fixing mechanism, a first card slot, a card block, a reed and a second card slot, workers can quickly connect the first air-conditioning duct with the second air-conditioning duct, thereby improving the efficiency of workers in installing the first air-conditioning duct and the second air-conditioning duct. By providing a first soft pad, a second soft pad, a first fixed frame and a second fixed frame, the sealing between the first air-conditioning duct and the second air-conditioning duct can be improved. By providing a filter component, the odor inside the vehicle body can be filtered.

[0004] The existing technology filters the passing air through the filter assembly, but the filter assembly will accumulate dust over time and gradually lose its filtering effect. It is usually necessary to disassemble the air conditioning system for manual cleaning or replace the filter, which is relatively troublesome in actual use. If the filter is not cleaned or replaced for a long time, excessive dust accumulation will cause the air duct to be blocked or the filtering efficiency to decrease, and the air circulation will be weakened, affecting the performance of the air conditioning system. Dust accumulation on the filter may cause mold growth, thereby producing odor and affecting the air quality in the car.

[0005] In summary, the prior art lacks a technology for automatically cleaning the filter components in the air duct of an automobile air conditioner. Summary of the invention

[0010] Preferably, a limiting groove is provided on the lower surface of the filter plate, and the limiting groove is movably plugged with the mounting bar.

Regular cleaning of the filter plate can prevent excessive dust accumulation, maintain the performance of the filter plate, and extend its service life, so that the air circulation efficiency will not be affected due to the blockage of the filter plate;

[0018] 2. By setting up a transmission mechanism, the automatic dust cleaning mechanism can be driven to automatically approach the filter plate while the sealing plate is retracted and released. At the same time, by setting up fan blades on the mobile frame, the fan blades can be driven to rotate while the automatic dust cleaning mechanism is in use, which is conducive to the discharge of cleaned dust from the dust outlet, which helps to remove the dust on the filter plate. It can also provide additional airflow support during the dust cleaning process, so that the cleaned dust can be quickly taken away to avoid dust re-deposition on the filter plate surface;

[0019] 3. By setting up a sealing plate, the air inlet and outlet ducts can be blocked when the filter plate is cleaned, effectively preventing dust from entering the air inlet and outlet ducts during cleaning, thereby preventing dust from contaminating other parts of the system or being re-inhaled into the car air-conditioning duct, ensuring the smooth progress of the cleaning work, and also preventing the risk of secondary pollution.
