Embodiment Construction

[0037] In order to make the object, scheme and beneficial effect of the present invention more clear, the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments. First of all, it needs to be explained that the "tornado" mentioned in the present invention only refers to the rotating and rising airflow similar to the natural tornado in appearance, rather than the real natural tornado.

[0038] A kind of range hood embodiment that the present invention proposes, such as Figure 5 and 6 As shown, the range hood includes a fan system and two air inlets respectively connected with the fan system. Further, the range hood also includes two tornado generating devices 1 respectively arranged under the two air inlets. The tornado generating device 1 is used for cooperating with the fan system to guide the flow direction of the airflow, and then generate the tornado airflow flowing to the air inlet above the tornado gene...

Abstract

The invention provides a range hood and a whirlwind generating device thereof. The range hood comprises a fan system and wind inlets communicated with the fan system. The range hood also comprises the whirlwind generating device used for steering airflow directions together with the fan system and then generating whirlwind airflow flowing toward the wind inlets, wherein the whirlwind generating device comprises a hollow column body part and first flow jet parts; and the first flow jet parts are arranged on the inner wall of the hollow column body part and are used for jetting airflow toward the inner wall of the hollow column body part. As the whirlwind flow can be generated, the oil fume suction of the range hood is obviously increased, thus oil fume escape can be reduced and the oil fume suction effect can be promoted. Besides, as the whirlwind effect can be generated, the user experience can be promoted.

Description

【Technical field】 [0001] The invention relates to the field of range hoods. 【Background technique】 [0002] Range hood, also known as range hood, is a kitchen appliance that purifies the kitchen environment. It is installed on the top of the stove in the kitchen, and can quickly take away the waste burned by the stove and the oily fumes harmful to the human body produced during the cooking process, and discharge them to the outside, reduce indoor pollution, purify the indoor air, and have the safety guarantee function of anti-virus and explosion-proof . [0003] How to reduce the escape of oily fume, and then improve the effect of oily fume suction, has always been a technical problem that has attracted wide attention in this field, and it is directly related to the market competitiveness of range hood products. Aiming at the above-mentioned technical problems, various solutions have appeared in the prior art: for example, installing curtains to prevent oil fumes from esca...
