Abstract

The present invention provides a vertical air conditioner indoor unit, comprising: a housing with a first air supply port and a second air supply port on the front side; an air duct arranged in the housing and having an air inlet and a first air outlet and a second air outlet, the first air outlet faces the first air outlet, the second air outlet faces the second air outlet, and the air duct is used to guide the airflow in the housing to the The first air supply port, the second air supply port, and the inner wall of the air duct adjacent to the first air outlet is tapered in which the flow cross section gradually becomes smaller along the air flow direction; and the flow guide is provided An annular air outlet gap is defined in the air duct and its tapered part, which is used to guide the airflow to the annular air outlet gap so that the airflow gradually converges toward the center of the airflow under the guidance of the inner wall of the air duct and flows out of the airflow in sequence. The first air outlet and the first air supply port. The vertical air conditioner indoor unit of the present invention has stronger wind force and longer air supply distance.

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...
