Air rectification device and air conditioner

Abstract

The invention discloses an air fairing device. The air fairing device comprises fairing stop blocks and an air flue volute; a through-flow wind wheel of an air conditioner is contained in the air flue volute, and the air flue volute comprises a lower frame and an upper frame and guides air flow guided by the through-flow wind wheel of the air conditioner to an air outlet for flowing out, wherein the lower frame and the upper frame form an air flue of the air conditioner; the fairing stop blocks are arranged at the two ends, close to the air outlet, of the lower frame and each comprise a plurality of rows of wedge-shaped structures arranged in a tooth mode. The invention further discloses the air conditioner. According to the scheme, the flow speed of air flowing out can be increased partially, and the flowing instability is prevented; when backflow may cause a surge, the fairing stop blocks can stop backflow air flow, the surge sounds caused by the backflow air flow can be lowered, then the pulse surge sounds can be restrained, the technical problem that the pulse surge sounds exist in the air conditioner is solved, and the problem that condensation exists in the fairing stop blocks is solved.

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, consciously press down the molded line at the upper end of the air outlet. In the direction of the air outlet, the lower chassis of the diffuser section of the air outlet will form a low-speed zone relative to other positions of the air outlet. 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...

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
