Abstract

The invention provides a volute tongue structure. The volute tongue structure comprises a volute tongue front end which is connected with the side wall of an air outlet of a fan, a volute tongue rearend which is connected with a volute of the fan and a connecting piece for connecting the two ends into an integrated structure, wherein the volute tongue front end comprises a first volute tongue wall located on the motor mounting side and a second volute tongue wall on the blade mounting side, the bottoms of the two volute tongue walls are connected with the top of the connecting piece, and thetwo volute tongue walls are longitudinally connected into a V-shaped structure. The invention further provides a volute structure applying the volute tongue structure and a range hood. According to the volute tongue structure, the fan volute and the range hood which are provided in the utility model, the air pressure and the air noise can be effectively reduced, and the air outlet amount can be increased.

Description

technical field [0001] The invention belongs to the technical field of fans, in particular to the technical field of the volute tongue structure at the air outlet of the fan. Background technique [0002] With the rapid development of society and the improvement of the quality of life, consumers' requirements for household electrical appliances such as range hoods are increasing year by year. As a range hood manufacturer, in order to gain a larger market share, win a good reputation from consumers and bring high-quality experience to users, it is urgent to start with structural performance and appearance, optimize the structure of range hood products and Performance improvements. [0003] Through a large number of market research and related literature, most of the range hoods on the market use ordinary centrifugal fans and air duct volute structures. The noise of centrifugal fans is mainly the aerodynamic noise generated during the unsteady flow of gas, including basic Fr...
