Abstract

The invention provides a ceiling-type air conditioner indoor unit. The ceiling-type air conditioner indoor unit includes a shell, a heat exchanger and a laminar flow fan; the upper part of the side surface of the shell is provided with at least one air inlet, and the lower part of the side surface of the shell is provided with at least one air outlet; the heat exchanger is arranged in the shell with the rotation axis extending vertically; and the laminar flow fan is located under the heat exchanger. When the laminar flow fan runs, the laminar flow fan prompts the indoor air to enter the spaceabove the heat exchanger from the air inlet, and then flow downward through the heat exchanger to exchange heat with the heat exchanger to form heat exchange wind; and then the heat exchange wind is blown back into the room through the air outlet. The ceiling-type air conditioner indoor unit provided by the invention realizes multi-directional and large-scale air supply, reduces the air supply noise, and improves the noise quality.

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...
