Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more specifically, to an air duct component, an air conditioner cabinet and an air conditioner. Background Art

[0002] Air conditioners are currently commonly used indoor temperature and humidity control devices that can blow cold or hot air into the room according to demand.

[0003] Since hot air is lighter than cold air and is located at a higher position than cold air, when the air conditioner is in heating mode, the hot air blown from above will stay at a higher position in the room, which is not conducive to uniform mixing with the cold air at a lower position, resulting in a slow indoor temperature rise and poor user experience. In addition, as the concentration of carbon dioxide increases due to human activities, the inability to exchange fresh air or the improper location of the fresh air exchange will also reduce human comfort.

[0004] The prior art adopts reversible air-conditioning technology, and sets two air outlets, one upper and one lower. Then, through the operation of the upper and lower double fans, the air conditioner can discharge air from the upper air outlet under the action of one fan, or discharge air from the lower air outlet under the action of one fan. However, the existing reversible air duct set for the double fans has a long air duct opening, low wind pressure, and poor air supply capacity of the single fan, resulting in a large air volume loss in the air duct, a small air volume, and a short air supply distance, which affects the cooling or heating effect and affects the user experience.
