Ceiling-type air conditioner indoor unit

Abstract

The invention provides a ceiling-type air conditioner indoor unit. The ceiling-type air conditioner indoor unit includes a shell; the shell is provided with a circular air inlet and an air supply outlet; the bottom wall of the shell around the air inlet is a drainage surface extending radially outward from the edge of the air inlet and gradually extending downward in an inclined mode, and the drainage surface is a rotating surface coaxial with the air inlet; a laminar flow fan is arranged in the shell, and the laminar flow fan includes a plurality of annular discs arranged in parallel and at intervals; the annular discs are fixedly connected to each other, and the axes of the annular discs extend vertically; a flow guide piece is arranged at the air inlet, and the outer peripheral surfaceof the flow guide piece is a rotating surface that gradually expands radially outward from top to bottom and is coaxial with the air inlet, so as to guide the air to flow to the air inlet through thegap between the outer peripheral surface of the flow guide piece and the bottom surface of the shell; the drainage surface includes an arc-shaped transition section, an arc-shaped pressurizing sectionand an arc-shaped extension section which are smoothly connected successively from inside to outside in the radial direction; the outer peripheral surface of the flow guide piece includes a straight-line inclined section, an upper arc-shaped section and a lower arc-shaped section which are smoothly connected successively from top to bottom; and the distance between the top end of the arc-shaped transition section and the top end of the lower arc-shaped section is smaller than the distance between the bottom end of the arc-shaped extension section and the bottom end of the lower arc-shaped section.

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...
