Vertical air conditioner indoor unit

Abstract

The present invention provides a vertical air-conditioning indoor unit, comprising an air supply body, the front air supply port of which is oblong, and the inner wall of the air supply body adjacent to the air supply port is a tapered shape in which the flow cross section gradually becomes smaller along the air flow direction; The deflector is arranged on the rear side of the air outlet, including a front end surface and two first deflector surfaces and two second deflector surfaces respectively extending backward from the upper and lower sides and lateral sides of the front face, and the front end surface is oblong shape; the guide piece and the tapered part of the air supply body define an annular air outlet gap, and the guide piece guides the airflow to the annular air outlet gap, and the airflow is guided by the inner wall of the air supply body, and gradually converges towards the airflow center; the first guide The flow surface extends from the back to the front and gradually moves away from the central horizontal symmetrical plane of the flow guide and includes a connected first concave arc segment and a second convex arc segment; the second flow guide surface extends from the back to the front and It is gradually away from the central longitudinal vertical symmetry plane of the flow guide, and includes a third concave arc segment, a fourth convex arc segment and a fifth arc segment convex.

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. Contents of the invention [0004] The object...
