Detailed Description

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

In the following description, "upper", "lower", "left" and "right" refer to the orientation of the extractor hood relative to the user during use, and are only for convenience of description, and do not constitute any structural limitation.

As shown in fig. 1 and 2, 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. An oil collecting cup 4 with an upward opening 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.

The air inlet of the fan system 2 is arranged in this embodiment towards the left and/or right side wall of the installation space 13. The fan system 2 of this embodiment can be a single air inlet fan system or a double air inlet fan system, and when the fan system is a single air inlet fan system, the air inlet of the fan system 2 is arranged toward the left or right side wall of the installation cavity 13, and when the fan system 2 is a double air inlet fan system, one air inlet of the fan system 2 is arranged toward the left side wall of the installation cavity 13, and the other air inlet of the fan system 2 is arranged toward the right side wall of the installation cavity 13.
