Abstract

The invention provides a ceiling type air conditioner indoor unit. The ceiling type air conditioner indoor unit comprises a shell, a laminar flow fan and a heat exchanger, wherein an air inlet is formed in the bottom surface of the shell, and at least one air outlet is formed in the side surface; the rotating axis of the laminar flow fan vertically extends into the shell, air is sucked from the axial bottom of the laminar flow fan during operating, and laminar flow air is produced by the viscous effect of air and is blown outwards in the radial direction; the heat exchanger surrounds the laminar flow fan on the outer side of the laminar flow fan in the radial direction; and when the laminar flow fan operates, indoor air is promoted to enter the shell from the air inlet and then is sucked in, and then the indoor air is blown into the heat exchanger for heat exchange and is blown back to the interior through the at least one air outlet finally. Multi-direction large-range air supply of the ceiling type air conditioner indoor unit is realized, air supply noise is reduced, and 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...
