Air rectification device and air conditioner

Abstract

The invention discloses an air rectifying device. The air rectifying device comprises a rectifying baffle block and an air channel volute. A cross-flow wind wheel of an air conditioner is accommodated in the air channel volute. The air channel volute comprises an upper frame and a lower frame which form an air channel of the air conditioner. Airflow introduced by the cross-flow wind wheel of the air conditioner is guided to an air outlet by the air channel volute and flows out. The rectifying baffle block is arranged in a region radiated by an eccentric vertical line on the lower frame at a preset angle. The eccentric vertical line is a vertical line which is made towards the plane where the lower frame is located with the center of an eccentric vortex of the air channel of the air conditioner as the base point. The invention further discloses the air conditioner. According to the scheme, the air outlet interface of the air outlet is reduced, and the flow rate of outflowing air is locally increased, so that the dynamic pressure of the outflowing air is increased; accordingly, the higher the dynamic pressure of the outflowing air is, the higher airflow backflow static pressure can be overcome through the higher dynamic pressure of the outflowing air, so that air outside the air outlet is prevented from flowing back into the air outlet, and then pulsation and surging sounds are suppressed.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air rectifying device and an air conditioner. Background technique [0002] Ordinary split wall-mounted air conditioners (cross-flow wind wheels), some hang-ups take into account that the wind can be blown upward as much as possible during cooling, and the wind can be blown downward during heating, and at the same time prevent the wind from the air outlet from flowing back to the air inlet. In the air duct of the air outlet, the upper end of the air outlet is consciously pressed down, but in order to maintain the expansion angle of the air outlet expansion section, the lower end of the air outlet is also consciously pressed down, in the direction of the air outlet, under the expansion section of the air outlet The chassis will form a low speed zone relative to the rest of the air outlet. After long-term use, dust will accumulate on the filter, resulting in increased ...

AI Technical Summary

Problems solved by technology

After long-term use, dust will accumulate on the filter, resulting in increased air intake resistance and unsmooth air intake. When the speed is high, the air volume will decrease sharply compared with the normal state. The local wind speed is too small, and some low-speed areas are not enough to overcome the internal static pressure of the air duct. The gas outside the air outlet will flow back into the air outlet, which will cause pulsation and surge sound, which will affect users. experience
