Detailed Description

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

As shown in fig. 1 to 8, 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, an air inlet 21 of the fan system 2 is communicated with the smoke collecting cavity 12, and an air outlet 22 of the fan system 2 is arranged upwards. An oil collecting cup 4 with an upward opening 41 is arranged at the lower edge of the shell 1, and the bottom of the smoke inlet cavity 11 is connected with the oil collecting cup 4. 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.
