The ozone generator 5 starts to operate, the fan 2 is in a low-speed operation state (namely, the rotating speed of the fan is lower than that of the fan in a cooking state), air flow generated by the fan 2 enters a cavity where the ozone generator 6 is located through the air inlet 33, ozone generated by the ozone generator 6 enters the cavity 10 through the air outlet 41 under the action of the air flow, and as the air outlet 41 is positioned above the air inlet port 21 of the fan 2, the ozone can quickly enter the fan 2 after being dispersed in the cavity 10 under the action of the air flow, and is led into the air outlet cavity 3 through the rotation of the fan 2 after being dispersed in the cavity of the fan 2, so that dynamic circulation is formed in the sterilizing and purifying cavity 4, the cavity 10, the cavity of the fan 2 and the air outlet cavity 3, and the concentration of the ozone reaches dynamic balance in the range hood. The ozone can not be automatically dispersed under the action of no external force because the specific gravity of the ozone is greater than that of the air, and the air flow generated by the fan 2 is introduced through the air inlet 33, so that the ozone can be effectively dispersed and flowed, the ozone can be uniformly distributed in all parts of the interior of the range hood, the ozone concentration in all parts of the interior of the range hood is uniform, the ozone in all parts of the interior of the range hood can be timely supplied through the action of the air flow, the concentration non-uniformity caused by the automatic decomposition of the ozone is avoided, the ozone concentration can be dynamically balanced in the whole sterilization and deodorization process, and the treatment effect of the ozone on the interior of the range hood is ensured.
In the third state, the air outlet valve plate closes the air outlet 31, the partition 5 is in a horizontal state, the second air vent 682 overlaps the air inlet 33, the first air vent 681 overlaps the vertical side wall 32, the ozone generator 6 is in a sealed cavity, the air outlet valve plate 9 is vertically arranged in the air outlet 41, so that the air outlet 41 is opened, the heating device 7, the air inlet 33 and the air outlet 41 are in the same cavity, namely, the range hood is in a heating decomposition state at the moment. The heating device 7 starts to operate, and the cavity in which the heating device 7 is positioned is quickly heated, so that the ozone in the cavity is quickly decomposed. Meanwhile, the fan 2 keeps in a low-speed operation state, so that heated hot air can be quickly led into the inner cavity 10 through the air outlet 41 by air flow generated by the fan 2, after the hot air is dispersed in the inner cavity 10, the hot air is led into the inner cavity of the fan 2 and is led into the air outlet cavity 3 under the rotation of the fan 2, and accordingly the hot air is circulated in the sterilizing and purifying chamber 4, the inner cavity 10, the inner cavity of the fan 2 and the air outlet cavity 3, the heating decomposition of ozone in the range hood can be quickened, the inside of the range hood can be fully filled with the hot air, and bacteria are effectively prevented from breeding under the dry state. The above heating device 7 can be implemented in various ways, and in this embodiment, the heating device 7 is a heating tube.
