The invention relates to an adaptive noise reduction cover device with an air duct structure, which includes a cover plate, a driving motor and a gear, an upper frame is provided on the upper end of the cover plate, a lower frame is provided on the lower end of the cover plate, and a driving motor is provided on the upper frame. The drive motor is connected to the gear through the motor output shaft, and the cover is provided with an air inlet and an air outlet; the inner side of the cover is provided with a movable cover part, and the movable cover part includes two movable cover plates, two movable The top of the cover plate is equipped with a gear rack that meshes with the gear, and the lower end of the two movable cover plates is equipped with rollers, which move on the lower frame; the inner sides of the two movable cover plates are equipped with L-shaped movable sound-absorbing materials. The two L-shaped movable sound-absorbing materials fit each other; sound-absorbing materials are provided around the inner side of the cover plate; the self-adaptive noise-absorbing cover plate device of an air duct structure disclosed by the present invention can control the movable cover plate to drive the internal The L-shaped movable sound-absorbing material moves to change the size of the air inlet and outlet to achieve the purpose of changing the internal air duct.
Description
technical field [0001] The invention relates to an adaptive noise reduction cover device with an air duct structure, which belongs to the field of cover equipment. Background technique [0002] In the development and upgrading of home appliances, energy saving and noise reduction are always the common product goals of home appliances. But at the same time, large-capacity inter-cooling refrigerators also have problems such as high noise and high energy consumption that are difficult to solve. The above-mentioned technical problems have become a major obstacle to the development and progress of refrigerators. The air conditioner compressor cabin is noisy, and heat exchange is accompanied by the work. Faced with different working conditions, the engine compartment has requirements for heat preservation and heat dissipation, and also requires reduction of noise radiation. Therefore, it is very important to research and explore the design of the cooling air duct in the power ca...
