Abstract

The invention discloses an air conditioner which comprises a shell, a first air inlet, a second air inlet, a first air outlet and a second air outlet, a mounting cavity is formed in the shell, and the shell is provided with a first air outlet communicating with the mounting cavity; the first fan is arranged in the mounting cavity, the first fan comprises a first volute and a first cross-flow fan blade arranged in the first volute, the first volute comprises a first volute main body section, and a first air guide wall is formed on the side, facing the first cross-flow fan blade, of the first volute main body section; a first tangent section, a first arc section and a first linear section are sequentially formed on a plate body of the first volute rear extending section in the direction from the first air guide wall to the first air opening, the first tangent section is connected and tangent to the first air guide wall, and the linear section is connected with the first air opening.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner. Background technique [0002] At present, the times are progressing. The traditional wall-mounted air conditioner has a monotonous appearance and a unique air outlet method. The pressure angle is small, the air inlet resistance is large, and there is obvious backflow at the back of the volute at the air outlet, and single or multiple air vortices are formed at the backflow, which not only reduces the air output of the air conditioner, but also increases the vortex noise of the air conditioner , At the same time, the cold air returned during cooling also causes condensation on the lower edge of the air outlet. Therefore must provide a kind of air conditioner that can solve the air-conditioning air volume and noise problem that causes because of the air vortex at volute place. Contents of the invention [0003] In view of this, the present invention...
