Problems solved by technology

Although the thin structure range hood has a beautiful appearance, takes up less space, does not block the operator's sight, and does not restrict and hinder the operator's actions during cooking, it has a poor effect on the caged smoke, resulting in the exhaustion of the oil fume. low rate
Deep and cabinet-type range hoods have a better effect on cage smoke. However, because they occupy a lot of space, they block the operator's sight and make the operator somewhat cramped and inconvenient when cooking; Modern and stylish kitchen furniture is not easy to match

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] In the embodiment shown in FIG. 1 , the air curtain fan 1 is a cylindrical centrifugal fan whose length is equal to that of the air distribution opening 3 . The quantity is two, located on both sides of the range hood. The air volume generated by the rotation of the air curtain fan 1 is transported to the air distribution outlet 3 through the air duct 2, and forms an air curtain after blowing out to prevent the oil fume from escaping.

[0014] figure 2 In the shown embodiment, only one air curtain fan 1 is used. In order to allow enough space for the passage of oil fume, the air curtain fan 1 uses a short centrifugal fan, and the air volume generated is transported to the air distribution outlet 3 through the air duct 2. In order to achieve the uniformity of the air volume, deflectors can be arranged in the air duct 2.

Description

technical field [0001] The invention relates to a range hood, in particular to a smoke cage structure of the range hood. Background technique [0002] At present, there are three types of range hoods for home use, as far as the structure of the smoke cage is concerned, thin type, deep type and cabinet type. Although the thin structure range hood has a beautiful appearance, takes up less space, does not block the operator's sight, and does not restrict and hinder the operator's actions during cooking, it has a poor effect on the caged smoke, resulting in the exhaustion of the oil fume. rate is low. Deep and cabinet-type range hoods have a better effect on cage smoke. However, because they occupy a lot of space, they block the operator's sight and make the operator somewhat cramped and inconvenient when cooking; Modern and stylish kitchen furniture is not easy to match.
