Vertical air conditioner indoor unit

Abstract

The invention provides a vertical air conditioner indoor unit which comprises an air supply body, an air supply outlet in the front side of the air supply body is long circular, and the inner wall, close to the air supply outlet, of the air supply body is in a gradually-reduced shape with an overflowing section gradually reduced in the airflow direction. A flow guide piece is arranged on the rearside of the air supply outlet and comprises a front end face, two first flow guide faces and two second flow guide faces, and the two first flow guide faces and the two second flow guide faces extendbackwards from the upper side, the lower side and the two transverse sides of the front end face respectively. The front end face is long-circular. An annular air outlet gap is defined by the flow guide piece and the gradually-shrinking part of the air supply body, the flow guide piece guides airflow to the annular air outlet gap, and the airflow is guided by the inner wall of the air supply bodyto gradually gather towards an airflow center. The first flow guide faces extend from back to front, are gradually far away from the central horizontal symmetric surface of the flow guide piece and each first flow guide face comprise a first concave arc-shaped section and a second convex arc-shaped section which are connected with each other. The second flow guide faces extend from back to front,are gradually far away from the central longitudinal vertical symmetrical surface of the flow guide piece, and each second flow guide face comprises a concave third arc-shaped section, a convex fourtharc-shaped section and a convex fifth arc-shaped section which are connected with one another.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a vertical air conditioner indoor unit. Background technique [0002] Compared with the wall-mounted air conditioner indoor unit, the vertical air conditioner indoor unit has a larger number of horses and stronger cooling and heating capabilities, and is usually placed in a larger indoor space such as the living room. [0003] Since the indoor unit of the vertical air conditioner has a larger coverage area, it needs to have stronger long-distance air supply capacity and strong air output capacity. In order to realize long-distance air supply in existing products, the method of increasing the fan speed is usually used to increase the wind speed and air volume. However, the increase in fan speed will lead to a series of problems such as increased air conditioning power and increased noise, which will affect user experience.
