Volute tongue structure, wall-mounted unit and air conditioner

Abstract

The invention provides a volute tongue structure, a wall-mounted unit and an air conditioner. The volute tongue structure comprises a first tongue plate and a tongue tip plate. The first tongue plateis arranged near a cross-flow fan, one end of the tongue tip plate is connected with the first tongue plate, the first tongue plate is connected with a driving assembly, and the driving assembly is used for adjusting the gap between the first tongue plate and the cross-flow fan. According to the volute tongue structure, through the combined design of a volute tongue and the flexible design of a connecting rod connected with the volute tongue, the gap between the first tongue plate and the cross-flow fan can be reduced at the initial running moment of the air conditioner, the air pressure and the air outlet speed at the tongue tip plate are increased, the flow is increased, the heat exchange efficiency is improved, after the room temperature is stable, the gap between the first tongue plateand the cross-flow fan is increased, the impact of the air pressure and the airflow at the tongue tip plate on the volute tongue structure is reduced, noise is lowered, meanwhile, the position changeof the first tongue plate is controlled in real time according to the working condition change, and the effects of rapid cooling, energy conservation and noise reduction can be achieved.

Description

technical field

[0001] The invention belongs to the technical field of air conditioning, and in particular relates to a volute tongue structure, a wall hanging machine and an air conditioner. Background technique

[0002] In the current air conditioner industry, the structure and position of the volute tongue of the wall-mounted machine are fixed, and the gap between the volute tongue and the impeller cannot be adjusted according to the change of working conditions, and the gap between the volute tongue and the impeller has a significant impact on the air volume and noise . Contents of the invention

[0003] Therefore, the technical problem to be solved by the present invention is that the structure and position of the volute tongue are fixed, and the gap cannot be adjusted according to the working conditions, thereby providing a volute tongue structure, a wall-mounted machine and an air conditioner.

[0004] In order to solve the above problems, the present invention pro...
