In one embodiment, referring to Figures 2 and 7, the illuminating lamp 22 is located at a corresponding position on the upper side of the front side plate 111, and the upper side of the upper cover 116 is a transparent plate. When the upper cover 116 is opened, it can be shielded from the illumination The lamp 22 can protect the illuminating lamp 22 and prevent oily smoke generated by cooking from adhering to the illuminating lamp 22 to facilitate cleaning.

In one embodiment, referring to FIG. 8, the illuminating lamp 22 is located at a corresponding position on the upper side of the front side plate 111, and when the upper cover 116 is opened, the upper side of the upper cover 116 is located below the illuminating lamp 22. This structure can facilitate The color of the upper cover 116 is set.

In one embodiment, referring to FIG. 9, the lower cover 114 is at least two pieces arranged side by side along the length of the box 10, and the number of the lower driving mechanism 115 corresponds to the number of the lower cover 114 one-to-one. When the dual-intake range hood 100 covers multiple stoves, multiple lower cover plates 114 and corresponding lower driving mechanisms 115 are provided. If only part of the stoves is used, only the lower cover at the corresponding position of the stove can be opened The plate 114 allows a part of the lower air inlet 112 to inhale, so as to inhale quickly, improve the efficiency of air inhalation, and reduce noise.

The above are only optional embodiments of the present application, and are not used to limit the present application. For those skilled in the art, this application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included in the scope of the claims of this application.
