Description

Centrifugal wind wheel structure suitable for fan

Technical Field

The utility model belongs to the technical field of the flue gas emission anti-downdraught technique and specifically relates to a centrifugal wind wheel structure suitable for fan.

Background

The gas stove is a kitchen utensil which is heated by direct fire with gas fuels such as liquefied petroleum gas, artificial gas, natural gas and the like, is also a national standard energy-saving periodic operation stove, and has good energy-saving effect. When the gas stove is used in high-rise or often windy places, normal combustion of gas can be influenced due to large outdoor wind power, and use and safety of users can be influenced in severe cases. If when wind power is too large, the flue gas can not be discharged normally, thereby influencing the combustion of the fuel gas and reducing the efficiency. In addition, when wind flows backwards and enters the gas furnace, the conditions of backfire and flameout can be caused, and dangerous conditions such as excessive CO and the like can be generated in the serious condition. As the air is easy to flow backwards when wind exists, particularly when the wind is strong, the smoke which is supposed to be discharged is caused to flow backwards into the room, on one hand, the smoke in the room is choked, the furnace combustion can be influenced after the wind enters, on the other hand, the personal safety is threatened, the carbon monoxide poisoning is easy to occur, and the people in the room can suffocate and die in serious cases.
