Air duct three-way joint for ceiling unit

Abstract

The invention provides an air duct three-way joint for a ceiling unit and belongs to the field of ventilating pipes. The air duct three-way joint comprises a ceiling fan, a reducing air duct, a three-way air duct, a linear air duct and a connecting board, wherein the ceiling fan is provided with a round air outlet flange; a round ventilating opening is formed in one end of the reducing air duct, a rectangular ventilating opening is formed in the other end of the reducing air duct, the connecting board is arranged on the inner side of the rectangular ventilating opening which is provided with an aperture enlarging part, the round ventilating opening is provided with an aperture reducing part, and the aperture enlarging part and the aperture reducing part are connected; the three-way air duct comprises a communicating part and a corner part communicating to the middle of the communicating part, the section shape of the communicating part corresponds to the rectangular ventilating opening, and the connecting board is arranged at one end of the communicating part and the corner part; the section of the linear air duct is rectangular, and openings in one end and in the other end of the linear air duct correspond to the rectangular ventilating opening; and the rectangular ventilating opening, the three-way air duct and the linear air duct are in inserting connection through the connecting board. A pipeline can be turned, wind noise can be reduced, and ceiling space can be saved.

Description

technical field [0001] The invention provides an air pipe tee of a ceiling unit, which belongs to the field of air pipes. Background technique [0002] The layout of the house is various. Sometimes when installing a ceiling fan, it is often equipped with multiple air outlets. Therefore, when the pipe reaches each air outlet, a section of pipe needs to be separated to connect to each air outlet. The existing method is to use The branch connection of the canvas will cause relatively large wind noise, and the installation of the air duct of the ceiling unit currently adopts a soft canvas variable-diameter connection. Using a soft canvas connection has the problems of complicated processing and assembly, large wind noise, and irregular installation. The air duct with reduced diameter is still circular after the diameter is reduced, and the circular air duct ceiling is installed on the top of the wall. For the sake of beauty, the ceiling decoration will be carried out under the a...

[0002] The layout of the house is various. Sometimes when installing a ceiling fan, it is often equipped with multiple air outlets. Therefore, when the pipe reaches each air outlet, a section of pipe needs to be separated to connect to each air outlet. The existing method is to use The branch connection of the canvas will cause relatively large wind noise, and the installation of the air duct of the ceiling unit currently adopts a soft canvas variable-diameter connection. Using a soft canvas connection has the problems of complicated processing and assembly, large wind noise, and irregular installation. The variable diameter air duct, after the diameter reduction, the air duct is still circular, and the circular air duct ceiling is installed on the top of the wall. For the sake of beauty, the ceiling decoration will be carried out under the air duct, which greatly wastes the ceiling space
