Volute and warmer

The utility model relates to the technical field of bathroom electric appliances, and discloses a volute and a warmer, the volute comprises: a main body in which an air duct is formed, and the two ends of the air duct are respectively provided with an air outlet and an air blowing port; the first volute tongue is located in the air duct and is arranged close to the air blowing opening; the second volute tongue is positioned in the air duct and is arranged close to the air outlet; in the air flow direction, an air channel between the first volute tongue and the fan is gradually widened, and an air channel between the second volute tongue and the fan is gradually widened. According to the volute, the pressure loss generated by air flow on the inner wall of the volute is reduced, so that the air flow uniformity of the air blowing opening and the air exhaust opening is high, air flow backflow is reduced, the flow field is greatly improved, and the service life of the volute is prolonged. The water vapor discharge
