Abstract

The present invention provides a ceiling-mounted air-conditioning indoor unit, which includes a shell with a circular air inlet and an air supply port. The bottom wall of the shell around the air inlet extends radially outward from the edge of the air inlet and gradually slopes downward. The drainage surface is a rotary surface coaxial with the air inlet; the laminar flow fan is arranged in the casing, including a plurality of annular discs arranged in parallel and spaced apart and fixedly connected to each other, and the axes all extend vertically; the flow guide is arranged at the inlet At the tuyere, the outer peripheral surface is a rotary surface that gradually expands radially outward from top to bottom and is coaxial with the air inlet to guide the air to flow to the air inlet through the gap between the outer peripheral surface of the air guide and the bottom surface of the shell; From the inside to the outside, it includes a smoothly connected arc-shaped transition section, an arc-shaped booster section, and an arc-shaped expansion section; The lower arc segment; the distance between the top of the arc transition segment and the top of the lower arc segment is smaller than the distance between the bottom end of the arc extension segment and the bottom end of the lower arc segment.

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] Traditional household air conditioners are usually cabinet units or on-hook units. Air conditioner cabinets and indoor units on-hook usually have only one air supply port to supply air to the room. Moreover, the cabinet machine and the hanging machine are limited by the structure, which can only supply air in one direction, and the air supply direction is relatively single. [0003] In addition, although there are air deflectors and swing leaves to guide the air, the air supply range of traditional air conditioner cabinets or hanging units is still not large. Contents of the invention [0004] An object of the present invention is to provide an air conditioner indoor unit capable of multi-angle and omni-directional air supply. [0005] Another object of the present invention is to stabilize...
