本实用新型涉及到一种吸油烟机。The utility model relates to a range hood.
背景技术Background technique
在现有技术中，市面上的吸油烟机大多为离心吸油烟机，离心吸油烟机由于占用空间不大，而且噪音低，吸力和风量也大等优点，受到越来越多的消费者青睐。离心风机作为吸油烟机的核心部件，通常由：蜗壳、电机、风轮、进风圈组成。当电机带动风轮旋转时，产生的离心力带动气体在进风圈外产生旋转涡流，此时进入风机的气流不均匀，从而影响风机的效率，易在进风处产生较大的噪音，致使存在影响风机效率，且噪音较大等缺陷。为克服这些缺陷，对吸油烟机进行了改进。In the prior art, most of the range hoods on the market are centrifugal range hoods, which are favored by more and more consumers due to their small footprint, low noise, and large suction and air volume. . As the core component of the range hood, the centrifugal fan usually consists of a volute, a motor, a wind wheel, and an air inlet ring. When the motor drives the wind wheel to rotate, the centrifugal force generated drives the gas to generate a rotating vortex outside the air inlet circle. At this time, the airflow entering the fan is not uniform, which affects the efficiency of the fan, and it is easy to generate large noise at the air inlet, resulting in Affect the efficiency of the fan, and the noise is large and other defects. In order to overcome these defects, the range hood has been improved.

挡流板5安装在进风圈4的中部。The baffle 5 is installed in the middle of the air inlet ring 4 .
挡流板5通过焊接、铆接或插铆固定于进风圈4上。The baffle 5 is fixed on the air inlet ring 4 by welding, riveting or riveting.
挡流板5的形状为平板型或S型。The shape of the baffle 5 is flat or S-shaped.
挡流板5固定在进风圈4上，挡流板5水平方向的高度比进风圈4高出20～50mm，优选的高度比进风圈4高出30～40mm。The baffle 5 is fixed on the air inlet ring 4, and the height of the baffle 5 in the horizontal direction is 20-50 mm higher than the air inlet ring 4, preferably 30-40 mm higher than the air inlet ring 4.
在进风圈4上增设档流板5，其水平方向的高度比进风圈4高，由于挡流板5的存在，气体进入风机时就不会在进风圈外产生旋转涡流，能使气体可以均匀的进入风机，能有效提高油烟机的全压效率，降低噪音。A baffle 5 is added on the air inlet circle 4, and its horizontal height is higher than that of the air inlet circle 4. Due to the existence of the baffle plate 5, when the gas enters the blower fan, a rotating vortex will not be generated outside the air inlet circle, which can make The gas can evenly enter the fan, which can effectively improve the total pressure efficiency of the range hood and reduce noise.
