It generates, so as to be impacted to the health of kitchen environment and user.
For traditional range hood generally without bactericidal purifying function, ozone is a kind of very strong gas of sterilizing ability,
Sterilizing ability is 3000 times or so of chlorine, has patent and is applied in the bactericidal purifying of range hood, such as：Application No. is
The Chinese invention patent of 201110258991.X (application publication number is 102966987 A of CN) discloses one kind, and there is disinfection to remove
Smelly multi-functional smoke suction device, inside ozone generator is installed, ozone generator outlet is connected to a solenoid valve control
Threeway, the outlet of threeway one end are directed toward housing cavity, shell are fastened on to sealing ring and clamp nut after other end stretching housing is outer
On body wall, threeway external part is connected with a leather hose.The inlet scoop of the device is able to turn on or off, thus can realize the device operation and it is static
Ozone goes mouldy the germ of growth because accumulating greasy dirt to its inside under state and the foul smell that distributes is carried out disinfection and removed.
Device in above-mentioned patent generates ozone in range hood by setting ozone generator, using ozone generator
Portion carries out bactericidal purifying, but ozone generator is chronically in the oil smoke surroundings inside range hood, a large amount of greasy dirts or dust
Attachment can make the short circuit of ozone generator and damage ozone generator, so as to influence the effect of its bactericidal purifying.Into one
Step, the proportion of ozone molecule are more than air, thus the ozone that generates of ozone generator will not automatic disperse, so as to cause fume-exhausting
Ozone concentration is uneven inside machine, i.e., the ozone concentration near ozone generator is higher, and the ozone concentration of ozone generator distant place
It is relatively low, and ozone molecule is extremely unstable, it is easy to it decomposes, has been further exacerbated by range hood inside ozone concentration so not
, and ozone plays the effect of effective sterilizing deodoring and need to reach certain concentration and act on the regular hour.As it can be seen that existing tool
The structure for having the range hood of ozone generator gives full play to ozone sterilizing deodoring function and causes limitation, need further
It improves.
