Abstract

The invention provides a suspended ceiling type air conditioner indoor unit. The suspended ceiling type air conditioner indoor unit comprises a shell, a heat exchanger and a laminar flow fan, whereinthe bottom of the shell is provided with an air inlet, and the side surface of the shell is provided with at least one air outlet; the heat exchanger is arranged in the shell and is adjacent to the air inlet; and the rotation axis of the laminar flow fan is arranged in the shell in a vertical extending mode, and laminar flow air is generated by utilizing the viscous effect of air during operation,so that indoor air is promoted to enter the shell from the air inlet and is blown back into a room through the air outlets after being subjected to heat exchange with the heat exchanger. According tothe suspended ceiling type air conditioner indoor unit, multi-directional and wide-range air supply is realized, the air supply noise is reduced, and the noise quality is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a ceiling-mounted air conditioner indoor unit. Background technique [0002] Existing indoor units of air conditioners basically use cross-flow fans, and the air outlet direction is the front. Although there are air deflectors to guide the flow left and right, and swing leaves to guide the flow up and down, but due to the structure of the volute, the left and right air supply angle is usually less than 80° , The upper and lower air supply angles are usually less than 100°. It can be seen that the existing indoor units have fewer air supply directions, and the air supply range is very limited. [0003] Moreover, the current cross-flow fan mainly has forward blades, and the blades periodically impact the passing air flow, resulting in obvious rotating noise. The volute cooperates with the fan to achieve the air supply effect, and the front and rear volute tongues will al...
