Description
技术领域technical field
本实用新型涉及制冷设备领域，更具体而言，涉及一种空调器室内机和包括该空调器室内机的空调器。The utility model relates to the field of refrigeration equipment, in particular to an indoor unit of an air conditioner and an air conditioner including the indoor unit of the air conditioner.
背景技术Background technique
目前，空调室内挂机或柜机很多都是采用贯流风轮进行送风，传统的贯流风道都是采用V字型扩张结构，当风轮转速较高，风量较大时，出风口处气流会充满整个出风口，这时，出风口处后蜗舌的壁面处不会出现蜗流和回流的现象，出风连续性较好，舒适性也较好，但当室内机调至低风档，风轮转速较低时，气流沿着蜗壳的前蜗舌的壁面流出，后蜗舌的壁面处气流较弱，就会出现负压，形成蜗流和回流，阻挡了低速气流的流出，进而出现了出风不稳、不连续的现象，且出风口可能会出现凝露现象。尤其是呈S型的贯流风道，其在后蜗舌拐弯处的一定角度范围内更容易出现出风不稳、不连续的现象，降低了出风的舒适性，并增大了出风噪音和异音。At present, many air-conditioning indoor hanging units or cabinet units use cross-flow wind wheels to supply air. Traditional cross-flow air ducts use V-shaped expansion structures. When the speed of the wind wheel is high and the air volume is large, the air flow at the air outlet will Fill the entire air outlet. At this time, there will be no spiral flow and backflow phenomenon on the wall of the rear volute tongue at the air outlet. The continuity of the air outlet is better and the comfort is better. But when the indoor unit is adjusted to the low wind gear, When the speed of the wind wheel is low, the airflow flows out along the wall surface of the front volute tongue of the volute, and the airflow at the wall surface of the rear volute tongue is weak, and negative pressure will appear, forming a vortex flow and backflow, blocking the outflow of low-speed airflow, and then The air outlet is unstable and discontinuous, and condensation may appear at the air outlet. In particular, the S-shaped cross-flow air duct is more likely to have unstable and discontinuous air outlet within a certain angle range at the corner of the rear snail tongue, which reduces the comfort of the air outlet and increases the noise of the air outlet and different sounds.
