The invention provides a volute tongue part, a draught fan device and an air conditioner. The volute tongue part comprises a volute tongue main body and a guide wheel, the volute tongue main body is rotatably arranged in a volute part around a preset axis, a pressurization starting end is arranged on the volute tongue main body, the guide wheel is arranged on the volute tongue main body and located at one end, away from the pressurization starting end, of the volute tongue main body, in the direction surrounding the preset axis, part of a wheel body of the guide wheel protrudes out of the volute tongue main body, and when the volute tongue main body moves towards the preset position of the volute part in the preset direction, the wheel body makes contact with a sharp corner structure before making contact with the sharp corner structure of the volute part so that a role in guiding the volute tongue body is achieved. The volute tongue part solves the problem that in the prior art, a movable volute tongue in a draught fan is prone to deformation, and consequently, normal work of the volute tongue is affected.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a volute tongue component, a fan device and an air conditioner. Background technique [0002] The volute tongue in the fan of the vertical air conditioner in the prior art is a fixed structure, but for the vertical air conditioner with reversible air supply, it is necessary to design a volute tongue that is movable relative to the volute to change The direction of the wind can realize the function of reversible airflow. [0003] However, the end of the moving volute tongue is likely to interfere with the volute due to deformation, produce abnormal noise or even get stuck, thereby affecting the normal operation of the volute tongue. Contents of the invention [0004] The main purpose of the present invention is to provide a volute tongue component, a fan device and an air conditioner to solve the problem in the prior art that the movable volute tongue in the fan is eas...
