Problems solved by technology

[0002] At present, European-style range hoods have no noise reduction structures on both sides of the fan. When the fan rotates, the strong airflow is directly sucked in through the two air inlets on both sides of the fan, forming vortices or turbulence at the two air inlets on both sides of the fan. flow, making the noise at the air inlet higher

Embodiment

[0013] Embodiment: A range hood with a noise-reducing structure, which includes a centrifugal wind turbine set 1 and an air duct housing 2, the centrifugal wind turbine set 1 includes a wind wheel, a motor and a volute, and the centrifugal wind turbine The wheel set 1 is arranged in the air duct housing 2, and the air inlet of the air duct housing 2 is perpendicular to the air intake surface of the centrifugal wind wheel set 1. Based on the installation and use direction, the inner side of the air duct housing 2 is in line with the air intake surface. The two opposite sides parallel to the radial plane of the wheel are respectively provided with a rectifying plate 3, and the two rectifying plates 3 are respectively located on the two opposite sides of the air inlet of the centrifugal wind turbine group 1, and the two rectifying plates 3 are fixed on the sides of the air duct housing 2. On the inner side, oil fume can pass through the rectifying plate 3 to reach the air inlet sm...

Abstract

The invention discloses a range hood with a noise reduction structure. The range hood comprises a centrifugal wind wheel set and an air duct shell, wherein the centrifugal wind wheel set comprises a wind wheel, a motor and a volute and is arranged in the air duct shell; an air inlet of the air duct shell is perpendicular to an air inlet surface of the centrifugal wind wheel set; two opposite side faces which are parallel to a radial surface of the wind wheel inside the air duct shell are provided with a rectification plate respectively in reference to the mounting and using direction; the two rectification plates are positioned on the two opposite sides of the air inlet position of the centrifugal wind wheel set respectively and are fixed inside the air duct shell; and due to the effect of the rectification plates, oil smoke cannot form turbulence at the air inlet and noise is not produced to fulfill the aim of reducing noise.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood with a noise reduction structure. Background technique [0002] At present, European-style range hoods have no noise reduction structures on both sides of the fan. When the fan rotates, the strong airflow is directly sucked in through the two air inlets on both sides of the fan, forming vortices or turbulence at the two air inlets on both sides of the fan. flow, making the noise at the air inlet higher. Contents of the invention [0003] In order to make up for the above shortcomings, the present invention provides a range hood with a noise-reducing structure, which can effectively reduce its noise. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: a range hood with a noise-reducing structure, which includes a centrifugal wind wheel set and an air duct housing, and the centrifugal wind wheel set includes a wind wheel, a mot...
