The invention provides a volute assembly which comprises a volute provided with at least one air outlet. The volute tongue is movably installed on the downstream side, in the airflow direction, of the air outlet, and the volute tongue can move in the radial direction of the volute so as to stretch out and retract back in the air channel. According to the volute assembly, the volute tongue structure moving in the radial direction of the air duct is adopted, the volute tongue structure only translates in one direction, the volute tongue serves as a flow guide component to guide airflow to the air outlet when stretching out, and when the volute tongue is retracted, the internal flow field resistance can be effectively reduced. The driving structure can be made more simply, the movement stability and reliability are higher, meanwhile, the movement range of the volute tongue can be increased in the mode that the volute tongue moves in the radial direction of the air channel, and the guide selectivity of the volute tongue to air outlet is more.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a volute assembly, a wall-mounted machine and an air conditioner. Background technique [0002] The wall-mounted unit with centrifugal fan can be designed with more air outlets to diversify the air supply mode of the air conditioner and meet the needs of more users. The design of multiple air outlets for centrifugal fans mostly adopts the motion design of the volute tongue to achieve the purpose of changing the number of air outlets and the direction of air outlet of the centrifugal fan. However, the existing cochlear tongue motion structures are generally complicated in structure, and the movement stability and reliability of the cochlear tongue are difficult to guarantee. SUMMARY OF THE INVENTION [0003] Therefore, the technical problem to be solved by the present invention is that the existing volute tongue motion structure is generally complicated in ...
