Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 3, the range hood of the present embodiment includes a housing 1 and a fan system 2 disposed in the housing 1. The lower part of the shell 1 is provided with a vertically extending smoke inlet cavity 11, the front side wall of the lower part of the shell 1 is provided with a smoke inlet 111 communicated with the smoke inlet cavity 11, the upper part of the shell 1 is provided with a smoke collecting cavity 12 communicated with the smoke inlet cavity 11, the smoke collecting cavity 12 extends forwards to form a mounting cavity 13 for mounting the fan system 2, it should be noted that the mounting cavity 13 is used for mounting the fan system 2, but the mounting position of the fan system 2 is not completely limited in the mounting cavity 13, and because the smoke collecting cavity 12 and the mounting cavity 13 are integrated, when the fan system 2 is mounted, the part of the fan system 2 can be positioned in the smoke collecting cavity 12 according to requirements. The air inlet of the fan system 2 can be arranged forward or backward, as long as the air inlet is communicated with the smoke collection cavity 12, and the air outlet of the fan system 2 is arranged upward. Because the smoke inlet cavity 11 at the lower part of the shell 1 vertically extends, the smoke inlet cavity 11 can be made thinner along the width in the front-back direction and can extend downwards to be sufficiently close to the cooker and a smoke generating source, so that the smoke can be quickly sucked into the smoke inlet cavity to be discharged upwards once being generated, and the smoke suction effect is improved.
