Problems solved by technology

[0002] In order to adjust the wind direction of the air outlet, the current air-conditioning internal unit generally adopts a flip-type adjustment plate. When the airflow hits the adjustment plate, due to the asymmetrical force on the upper and lower sides of the adjustment plate, there will be a large vibration noise. In addition, the strip-shaped upper edge of the adjusting plate itself constitutes the windward cutting edge for cutting the airflow, forming a large airflow tearing sound, which makes the air conditioner inner unit generate greater noise when the air is discharged.

Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0014] exist figure 1 In the shown first embodiment, the low-noise air conditioner indoor unit includes a cylindrical cross-flow fan 1, the end of the cross-flow fan 1 has an air inlet hole 10, and a rotating shaft 11 along the axis, and the cross-flow fan 1 is composed of a fan motor ( figure 1 (not shown in the figure) drive, when the cross-flow fan rotates, the airflow enters the inside of the cross-flow fan from the end and is discharged radially; 20, the airflow discharged radially by the cross-flow fan 1 is discharged from the axial slit 20 of the open cylinder 2; the open cylinder 2 is controlled by the steering control system, so that the open cylinder 2 can Rotate around the common axis of the open cylindrical body 2 and the cross-flow fan 1 .

[0015] In addition, the upper and lower edges of the axial slit 20 of the open cylinder 2 are rolled outward...

Abstract

The invention provides a low-noise air conditioner internal unit. The low-noise air conditioner internal unit comprises a cylindrical cross-flow fan. The cross-flow fan is driven by a fan motor. An open cylinder is arranged outside the cross-flow fan, is coaxial with the cross-flow fan and is provided with an axial notch. Air flow discharged by the cross-flow fan in the radial direction is discharged from the axial notch of the open cylinder. The open cylinder is controlled by a steering control system so that the open cylinder can rotate around the common axis of the open cylinder and the cross-flow fan. The air outlet direction of the low-noise air conditioner internal unit can be effectively adjusted, and the air outlet noise of the low-noise air conditioner internal unit is low.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an air conditioner inner unit. Background technique [0002] In order to adjust the wind direction of the air outlet, the current air-conditioning internal unit generally adopts a flip-type adjustment plate, and when the airflow hits the adjustment plate, due to the asymmetrical force on the upper and lower sides of the adjustment plate, there will be a large vibration noise, And the strip-shaped upper edge of the adjusting plate itself constitutes the windward cutting edge for cutting the airflow, forming a larger tearing sound of the airflow, so that the air conditioner inner unit produces a larger noise when the air is discharged. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a low-noise air-conditioning inner unit, which can not only effectively adjust the direction of the air outlet, but also has ...
