Abstract

The invention discloses an air duct type air conditioner indoor unit, which comprises an air outlet, an air outlet extension part arranged at the air outlet, and an active noise reduction device. A cavity is formed in the air outlet extension part, and the cavity communicates with the air outlet. The air outlet of the air outlet extension part is provided with a grille, and the active noise reduction device is arranged in the cavity. The Active Noise Cancellation can be serviced by removing the grille. Realize the front maintenance and maintenance convenience of the active noise reduction device, and meet the maintenance needs of the ducted air conditioner indoor unit in the hoisting usage scenario.

Description

technical field [0001] The invention relates to the technical field of air conditioner adjustment equipment, in particular to an air duct type air conditioner indoor unit. Background technique [0002] The ducted air conditioner includes an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit are connected by pipelines. Compared with the traditional central air conditioner, the air conditioning effect of the ducted air conditioner is almost the same as that of the central air conditioner, but the price of the ducted air conditioner is cheaper, and it is also hidden installation. Therefore, the ducted air conditioner has become popular in recent years. It has been favored by more and more consumers. [0003] In order to improve user comfort, reducing the noise generated by the indoor unit of the ducted air conditioner during operation is a problem that those skilled in the art have been working on. In the prior art, there is theoretical research on appl...
