Ceiling variable-diameter bending air pipe

Abstract

The invention provides a ceiling variable-diameter bending air pipe, and belongs to the field of ventilation pipes. The ceiling variable-diameter bending air pipe comprises a ceiling fan, wherein the ceiling fan is provided with a circular water outlet flange; a variable-diameter air pipe is arranged; a circular ventilation port is arranged in one end of the variable-diameter air pipe, and a rectangular ventilation port is arranged in the other end of the variable-diameter air pipe; a connection table is arranged at the inner side of the rectangular ventilation port; the rectangular ventilation port is provided with a diameter expansion part; the circular ventilation port is provided with a diameter reduction part; the diameter expansion part is connected with the diameter reduction part; a three-way air pipe is arranged; the three-way air pipe comprises a communication part and a corner part; the corner part is communicated to the middle position of the communication part; the section shape of the communication part corresponds to the rectangular ventilation port; a connection table is arranged at one end of the communication part and the corner part; a bent pipe is arranged; the section of the bent pipe corresponds to the section of a linear air pipe; and one end of the bent pipe is connected with the linear air pipe in an insertion manner through the connection table of the linear air pipe, and a connection table the same as the connection table of the linear air pipe is arranged at the other end of the bent pipe. A pipeline can be turned, an air noise can be lowered, and a ceiling space is saved.

Description

technical field [0001] The invention provides a suspended ceiling variable-diameter curved air duct, which belongs to the field of air ducts. 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 variable-diameter air duct, the air duct is still circular after the diameter is changed, and the circular air duct ceiling is installed on the top of the wall. For the sake of beauty, the ceiling decoration w...

[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, and the existing The variable-diameter air duct, the air duct 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 air duct, which greatly wastes the ceiling space. Sometimes the branch road needs to bypass the uneven part when the roof is uneven. The existing pipes generally use circular air ducts, which occupy a lot of ceiling space
