Abstract

The invention provides a volute, a fan and a range hood and relates to the technical field of purification equipment. The volute comprises a coaming and two side plates; the coaming is connected between the two side plates to form an air flue together in an enclosing manner; each side plate is provided with an opening; at least one side plate is provided with a flow guide area; the bottom edge ofthe flow guide area is coincided with the bottom edge of the corresponding side plate; and the flow guide area is inclined inwards from top to bottom. The fan comprises an impeller, a drive device andthe volute; the impeller is installed in the volute; and the drive end of the drive device is connected with the impeller and is used for driving the impeller to rotate. The range hood comprises a box body and the fan; the box body is provided with a smoke suction hole and a smoke exhaust which are mutually communicated; and the fan is installed in the box body. The fan applying the volute is relatively high in performance in the running process and small in generated noise pollution.

Description

Technical field [0001] The invention relates to the technical field of purification equipment, in particular to a volute, a fan and a range hood. Background technique [0002] The production process of traditional Chinese food culture includes frying, frying, frying, roasting, etc. A large amount of oil fume is generated during the food preparation process, and the oil fume not only pollutes the kitchen environment seriously, but also the kitchen operators are harmful to the body when they are in the oil fume environment for a long time Larger, serious, and even cancer. Therefore, range hoods are widely used in kitchens. [0003] The fan is the core component of the range hood, which is mainly used to suck the inside of the range hood into a negative pressure state, and promote the kitchen range hood to enter the interior of the range hood and be discharged to the outside through the fan; because the air inlet of the fan volute is set on its side , The air outlet of the fan is set...
