Technical Field

The utility model relates to an oil smoke purifier, especially a range hood.

Background

The range hood has become one of indispensable kitchen electrical appliances in modern homes, and generally the range hood comprises a top suction type and a side suction type. The air inlet of the top-suction type range hood is usually arranged right above the smoke source, generally, the air inlet of the top-suction type range hood is far away from the linear distance of the smoke source, and the top-suction type range hood has a good cooking operation space. And the air intake of side-draught range hood sets up in the upside side of smoke source usually, and generally, its air intake position is nearer apart from the straight line distance of smoke source, and under the same flow, the negative pressure zone of side-draught range hood is closer to the smoke source, and its smoking effect can be more outstanding than the top-draught range hood.

The utility model discloses a chinese utility model patent of application number 202122402075.0 discloses a top suction formula range hood, including the collection petticoat pipe, seted up the air intake on the collection petticoat pipe, air intake department is provided with the filter screen subassembly, and the filter screen subassembly includes first filter screen, and first filter screen has mutually independent at least two and control interval arrangement, and interval arrangement's net piece about every first filter screen includes at least two, constitutes air inlet channel between two adjacent net pieces, and the net piece can be around the rotation of the axle that the fore-and-aft direction extends.

Still like the utility model discloses a side-draught range hood as application number 202121551350.9's chinese utility model patent discloses, including casing and the panel of setting in the casing front side, the air intake has been seted up on the panel, range hood is still including setting up the baffle subassembly in the casing, the baffle subassembly is including controlling first baffle and the second baffle of arranging side by side, on oil smoke flow path, first baffle and second baffle are located the low reaches of air intake, the left side setting of first baffle corresponding air intake, the right side setting of second baffle corresponding air intake, first baffle and second baffle homoenergetic are round the axis rotation of extending around.

At present, the size and the height of common household cookware are different from each other, if a cookware with a low height is matched with a top-suction type range hood to be used, namely, the smoke source is far away from a smoke inlet in the vertical direction, the smoke rising path is long, so that the smoke is easy to diffuse and escape, if the cookware with a high height is matched with a side-suction type range hood to be used, the cooking space of a user is limited, and the user cannot turn the cookware or even influence cooking and cooking.

In addition, after the range hood is used for a long time, a large amount of oil stains can be adsorbed inside the range hood, especially the oil stains of a fan system are serious, and the oil stains can generate peculiar smell to be diffused into a kitchen, so that the life quality of people is influenced. If the range hood is connected into a public flue, the fire damper at the flue opening is not tightly closed, and the phenomena of smoke dumping and smell channeling can be caused. When the existing top-suction type range hood is in a non-working state, an air inlet of the existing top-suction type range hood cannot be closed normally, so that peculiar smell in the range hood and oil smoke from a public flue enter a kitchen environment.
