Embodiment Construction

[0021] The principle and structure of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0022] This application discloses a structure of air duct 1, such as figure 1 As shown, one end of the air duct 1 is an air inlet 11, and the other end is an air outlet 12, the air inlet 11 is arranged above the air duct 1, and the air outlet 12 is arranged below the air duct 1; There is a centrifugal fan 13 opposite to the air inlet 11. The centrifugal fan 13 is used to form negative pressure and form an air flow from the outside of the air duct 1 to the inside of the air duct 1. A heat exchanger 14 is also arranged in the air duct 1. The heat exchanger 14 It is arranged near the air outlet 12 and is used to exchange heat for the air in the air duct 1 .

[0023] The present application is provided with a water baffle 2 in the air duct 1, the water baffle 2 is arranged on the air outlet side of the heat exchanger 14, and the water b...

Abstract

The invention discloses an air duct structure and an air conditioner. The air duct structure comprises an air outlet, a water baffle arranged in an air duct and close to the air outlet, a vibrator arranged on the water baffle, a noise signal collecting module and a controller. The water baffle comprises a frame and at least one group of water baffle sheets arranged in the frame, and the vibrator is arranged on the frame; each group of water baffle sheets comprises a plurality of water baffle sheets, the cross section of each water baffle sheet is herringbone, and each water baffle sheet is provided with a flow guide groove; the plate surface of the water baffle is inclined to the cross section of the air duct; and the air duct structure further comprises a water pan communicated with the flow guide groove, sound absorption cotton is further attached to the inner wall of the air duct, and foaming rubber is further attached to the outer wall of the air duct. The vibrator is used for driving the water baffle to vibrate, and noise of the air outlet of the air duct is reduced by means of interference of sound waves; and meanwhile, the water baffle capacity of the water baffle is improved.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an air duct structure suitable for large air conditioners and an air conditioner using the air duct structure. Background technique [0002] In the current air conditioners, especially large air conditioners, due to the large air volume, the fan speed of the air conditioner is high, resulting in high noise, which seriously affects the customer experience. It is easy to be blown out from the air outlet, so a water baffle will be installed at the air outlet of the air-conditioning duct to block the wind. Since the outlet air contains a lot of water, the water baffle can effectively block the condensed water. Because the water and the blades of the water baffle The impact sound will further increase the noise of the air outlet. And in the existing technology, the noise is generally eliminated through the resonance of the resonant cavity, or the corresponding noise is fed back throug...
