On the other hand, the sterilization device 77, the first mounting seat 770 for mounting the sterilization device 77, and the first moving assembly 79 for driving the first mounting seat 770 to move are disposed in the purification chamber 74. In this embodiment, the sterilization device 77 is an ultraviolet lamp tube capable of generating ozone, and the sterilization device 77 can move back and forth between the air outlet chamber 73 and the purifying chamber 74 under the driving of the first moving assembly 79 and has at least two states: in the first state, the sterilizing device 77 is at least partially located in the air outlet cavity 73, and the first air inlet 733 and the first air outlet 741 are both opened; in the second state, the sterilizing device 77 is completely located in the purge chamber 74, and the first air inlet 733 and the first air outlet 741 are both closed.
On the other hand, the heating chamber 75 is provided with a heating device 78 for heating the gas, a second mount 780 for mounting the heating device 78, and a second moving assembly 70 for moving the second mount 780. In this embodiment, the heating device 78 is a far infrared heating tube, and the heating device 78 can be driven by the second moving assembly 70 to move back and forth between the air outlet chamber 73 and the purifying chamber 74 and has at least two states: in the first state, the heating device 78 is at least partially located in the air outlet cavity 73, and the second air inlet 735 and the second air outlet 751 are both open; in the second state, the heating device 78 is completely located in the heating chamber 75, and the second air inlet 735 and the second air outlet 751 are both closed.

In the sterilization and deodorization state, the air outlet valve plate closes the air outlet 731, the sterilization device 77 moves from the purification cavity 74 to the air outlet cavity 73, the first air inlet 733 and the first air outlet 741 are both opened, ultraviolet rays generated by the sterilization device 77 can irradiate the inner walls of the fans 72 and the air outlet cavity 73 (as shown in fig. 11), and when the ultraviolet rays completely enter the air outlet cavity 73, the optimal ultraviolet irradiation sterilization effect can be achieved on the inner walls of the fans 72 and the air outlet cavity 73 (as shown in fig. 12). Further, at this time, the fan 72 is in a low-speed operation state (i.e. the rotation speed of the fan is lower than that of the cooking state), the air flow generated by the fan 72 drives the ozone generated by the sterilizing device 77, the ozone gas enters the inner cavity 710 through the first air outlet 741 under the action of the air flow, and as the first air outlet 741 is located above the air inlet 721 of the fan 72, the ozone can quickly enter the fan 72 after being dispersed in the inner cavity 710 under the action of the air flow, and is led into the air outlet cavity 73 through the rotation of the fan 72 after being dispersed in the inner cavity of the fan 72, so that dynamic circulation is formed in the purifying cavity 74, the inner cavity 710, the inner cavity of the fan 72 and the air outlet cavity 73, and the concentration of the ozone reaches dynamic balance inside 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 72 is introduced through the first air inlet 733, 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 of all parts of the interior of the range hood is uniform, the ozone of 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.
After the sterilization and deodorization are finished, the air outlet valve plate continues to close the air outlet 731, the sterilization device 77 is closed, and the first air inlet 733 and the first air outlet 741 are closed at the same time.

The heating device 78 makes the heating cavity 75 quickly heat up, so that ozone entering the heating cavity 75 is quickly decomposed, meanwhile, the fan 72 keeps in a low-speed operation state, so that air flow generated by the fan 72 can quickly guide heated hot air into the inner cavity 710 through the second air outlet 751, the hot air is dispersed in the inner cavity 710 and then is guided into the inner cavity of the fan 72, and is guided into the air outlet cavity 73 under the rotation of the fan 72, so that the hot air is circulated in the heating cavity 75, the inner cavity 710 and the inner cavity of the fan 72 and the air outlet cavity 73, the heating decomposition of ozone inside the range hood can be accelerated, the inside of the range hood can be fully filled with the hot air, and bacteria are effectively prevented from breeding in a dry state. In addition, the heating device 78 entering the air outlet cavity 73 irradiates and heats the fan system and the inner wall of the air outlet cavity 73 directly by emitting far infrared rays, so that not only can the decomposition efficiency of ozone be further heated, but also the fan system and the air outlet cavity 73 can be enabled to be drier, and bacterial breeding is further prevented (as shown in fig. 11 and 12).
