Wall-mounted air conditioner indoor unit

Abstract

The invention provides a wall-mounted air conditioner indoor unit. The indoor unit comprises a shell, a volute tongue, a structural part and a flow guide part. A first air supply outlet is mounted atthe front side of the shell. The volute tongue is arranged in the shell, and the front end of the volute tongue extends to the position close to the upper portion of the first air supply outlet. The structural part is arranged in the shell, the front end of the structural part is close to the lower portion of the first air supply outlet, so that the structural part and the volute tongue jointly define an air outlet duct, and the inner wall, close to the first air supply outlet, of the air outlet duct is in a gradual shrinking shape with the overflowing section gradually becoming smaller in theairflow direction. The flow guide part is arranged in the air outlet duct, an air outlet gap is defined by the flow guide part and the gradually-shrinking part of the air outlet duct, and the flow guide part is used for guiding airflow to the air outlet gap, so that the airflow is guided by the inner wall of the air outlet duct to be gradually blown out of the first air supply outlet towards thecenter of the airflow in a gathered manner. The wall-mounted air conditioner indoor unit is longer in air supply distance and higher in air supply capacity.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a wall-mounted air conditioner indoor unit. Background technique [0002] Most of the existing wall-mounted air conditioner indoor units use a single cross-flow fan, and the air outlet is generally set at the lower front side of the indoor unit shell, which is relatively simple, resulting in a single appearance and structure of the wall-mounted air conditioner indoor units on the market. At the same time, the air supply angle is small and the air supply distance is short; the left and right, up and down air guidance is realized only by the air deflector and the swing blade, the cold air blows directly, the hot air blows down at a small angle, and the user experience is poor; The tuyere is generally set on the upper part of the shell, and can only enter the air from above, which cannot make full use of the heat exchanger. Contents of the invention [0003] The purpose ...
