Embodiment 1

[0037] Such as Figure 1-10 As shown, a range hood includes a casing 71 with an inner cavity 710 and an air outlet cover 711, the inner cavity 710 is provided with a fan 72, the above air outlet cover 711 is provided with an air outlet cavity 73, and the outlet The air chamber 73 is located above the inner chamber 710 and communicates with the inner chamber 710 through the air inlet 736. The top of the air outlet chamber 73 has an air outlet 731, and the air outlet 731 is provided with an air outlet valve plate capable of opening and closing the air outlet 731. (not shown, the air outlet valve plate can adopt a conventional structure in the prior art).

[0038] The air outlet hood 711 is also provided with a purification chamber 74 and a heating chamber 75 , which are arranged in parallel with the air outlet chamber 73 respectively, and all three are located above the inner chamber 710 . The purification chamber 74 has a vertically extending first side wall 732 shared with th...

Embodiment 2

[0047] Such as Figure 11 with Figure 12 As shown, the difference from Embodiment 1 is that in this embodiment, both the first mounting base 770 and the second mounting base 780 include a cylindrical cover body, and circular end caps are respectively fixed on both ends of the cover body. . The end cover of the first mounting base 770 adjacent to the first air inlet 733 (the end face of the end cover is the above-mentioned 7701) matches the first air inlet 733, and the end cover of the second mounting base 780 adjacent to the second air inlet 735 The end cover (the end face of the end cover is the above-mentioned 7801 ) is matched with the above-mentioned second air inlet 735 . The above-mentioned sterilizing device 77 and heating device 78 are respectively installed in the first mounting base 770 and the second mounting base 780, and the two ends of the first mounting base 770 are respectively provided with first ventilation holes 7703, and the first ventilation holes 7703 ...

Embodiment 3

[0049] Such as Figures 13 to 17As shown, the difference from Embodiment 1 is that in this embodiment, the purification chamber 74 and the heating chamber 75 are arranged side by side, and the air outlet chamber 73 is provided on one side of the two, and the air outlet chamber 76 is provided on the other side. The air outlet chamber 76 has a vertical side wall 762 common to the purification chamber 74 and the heating chamber 75 . The above-mentioned first air outlet 741 and second air outlet 751 have the same structure and are arranged in the air outlet chamber 76, that is, the air outlet 761 opened on the bottom wall of the air outlet chamber 76, and the air outlet is also located at the air inlet of the fan 72. above port 721. The purification chamber 74 and the heating chamber 75 communicate with the air outlet chamber 76 through the first vent hole 7621 and the second vent hole 7622 respectively, and the first vent hole 7621 and the second vent hole 7622 are set on the ve...

Abstract

The invention relates to an extractor hood. The extractor hood comprises an air outlet chamber and a purification chamber. The purification chamber and the air outlet chamber are arranged side by side. The purification chamber is provided with a first air inlet and a first air outlet. A sterilization device, a first mounting base and a first movement assembly are arranged in the purification chamber. The sterilization device is driven by the first movement assembly to move back and forth between the air outlet chamber and the purification chamber and at least has two states. In the first state, at least one part of the sterilization device is located in the air outlet chamber and the first and second air outlets are open. In the second state, the sterilization device is completely locatedin the purification chamber, and the first air inlet and the first air outlet are both closed. In the cooking state, the sterilization device can be placed in a closed space so that the soot-caused pollution damage to the sterilization device is avoided. The airflow generated by a fan can effectively diffuse and flow the ozone, so that the ozone concentration in the extractor hood is uniform and the treatment effect of ozone on the interior of the extractor hood is guaranteed.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood with sterilization and purification functions. Background technique [0002] The range hood is used to discharge the flue gas outside. After a period of use, the inside of the range hood tends to accumulate oil, such as the smoke collection hood and fan of the range hood. The long-term accumulation of oil stains will easily lead to the breeding of bacteria inside the range hood, and lead to the generation of peculiar smell, which will affect the kitchen environment and the health of users. [0003] Traditional range hoods generally do not have a sterilization and purification function. Currently, new type range hoods with sterilization and purification functions are generally equipped with ultraviolet lamps or ozone generators. Among them, ozone is a gas with strong bactericidal ability, its bactericidal ability is about 3000 times that of chlorine gas, and it has been ap...
