Air conditioner air outlet structure and air conditioner

Abstract

The invention discloses an air conditioner air outlet structure and an air conditioner. The air conditioner air outlet structure comprises a fan (1), an air supply duct (2) and a heat exchanger (3), wherein the fan (1) comprises a fan air inlet (4) and a fan air outlet (5), the air supply duct (2) is connected to the fan air outlet (5), the front side wall (6) of the air supply duct (2) extends to the side, close to the fan air outlet (5), of the heat exchanger (3) from the fan air outlet (5), and the rear side wall (7) of the air supply duct (2) extends to the other side, away from the fan air outlet (5), of the heat exchanger (3) from the fan air outlet (5). The heat exchanger (3) is arranged at an outlet of the air supply duct (2), and the section of the air supply duct (2) is gradually reduced in the direction away from the fan air outlet (5). The air conditioner air outlet structure is uniform in air output, and can effectively guarantee the air output efficiency of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air outlet structure of an air conditioner and an air conditioner. Background technique [0002] The traditional air conditioner has a small air outlet surface and a high airflow velocity. The wind speed passing through the human body surface is higher than the minimum wind speed perceived by the human body. The aerodynamic noise is obvious and the human body feels poor comfort. [0003] If the air outlet is set to supply air in a large area, the air will rush to the bottom of the channel due to inertia after entering the air flow channel at high speed after the fan does work, and will flow out from the lower end at high speed due to flow obstruction, and the upper end will be caused by internal high-speed air flow. Due to the jet flow effect, not only can no air flow out from the upper side of the heat exchanger, but even a "backflow phenomenon" in which the external...

[0002] Traditional air conditioners have a small air outlet surface and a high airflow velocity. The wind speed passing through the human body surface is higher than the minimum wind speed perceived by the human body. The aerodynamic noise is obvious and the human body feels poor comfort.

[0003] If the air outlet is set to supply air in a large area, the air will rush to the bottom of the channel due to inertia after entering the air flow channel at high speed after the fan does work, and will flow out from the lower end at high speed due to flow obstruction, and the upper end will be caused by internal high-speed air flow. The jet flow effect causes not only no air flow from the upper heat exchanger side, but even a "backflow phenomenon" in which the outside air is forced into the circulation channel, which not only produces uneven air flow, but also affects the air output efficiency of the air conditioner
