An automatic opening and closing device for the oil screen of a European-style range hood

Abstract

The invention discloses an automatic opening and closing device for the oil net of a European-style range hood, which comprises a chassis, a lifting mechanism and an oil net. The bottom of the chassis is provided with an air inlet, and the lifting mechanism is accommodated in a protective box, including a fixing plate and a side rail. , racks, motors and connectors, the fixing plate is fixed under the fan system inside the chassis, the track bracket is a cuboid structure, the upper end is fixed at the bottom of the fixing plate, side rails are provided on both sides, rack rails and motors are provided on the front Bracket, the rack is fixed on the rack rail, the motor is fixed on the motor bracket, the power output end of the motor is provided with a gear, and the gear is meshed with the rack. A connecting bump is arranged upward, the positioning groove is connected to the bottom of the side rail, the connecting bump is connected to the bottom of the rack, the outer bottom of the connector is connected to the oil net, the upper part of the oil net is provided with a protective net, and the lower part is provided with an oil cup. By adopting the above-mentioned structure, a clean and environment-friendly European-style range hood capable of blocking backflow of oil fume can be obtained.

Description

technical field [0001] The invention relates to an automatic opening and closing device for an oil net of a European-style range hood. Background technique [0002] The European-style range hoods currently on the market have a lot of long or round holes on the oil net. The oil fume is sucked by the fan system through these holes and then discharged to the outside. This European-style range hood absorbs a large amount of oil dirt on the oil net. In addition to the formation of surface pollution on the surface, after long-term use, the oil accumulated in the fan system will also be distributed into the kitchen environment through this mesh, polluting the kitchen environment. In addition, most of the urban houses are public flues at present, and the structure of the existing range hood check valve cannot effectively prevent the oil fume from other users from flowing back from the public flue, causing the fumes to flow back and pollute the kitchen air, seriously affecting people...

The oil fume is sucked by the fan system through these holes and then discharged to the outside. This European-style range hood absorbs a large amount of oil dirt on the oil net. In addition to surface pollution, after long-term use, the oil accumulated in the fan system will also be released into the kitchen environment through this mesh, polluting the kitchen environment

In addition, at present, most of the urban houses are public flues, and the structure of the existing range hood check valve cannot effectively prevent the oil fume from other users from flowing back from the public flue, causing the oil fume to flow back and pollute the kitchen air, seriously affecting people's health
