The present invention relates to a large-capacity exhaust system, and more particularly, to a large-capacity exhaust system capable of effectively exhausting oil vapor generated in a large capacity using a baffle-exhaust means having a baffle portion.

In general, the kitchen is a place for making food, and because food is cooked using a heating cooker such as a gas stove, when the food is cooked, contaminated air such as heat, steam, smoke, and smell is generated.

Accordingly, an exhaust system mainly for discharging the contaminated air to the outside is disposed above the countertop.

The exhaust system is largely a small exhaust system used in the kitchen of a normal home and a large capacity exhaust system used in a large kitchen, such as hotels, schools, restaurants.

Recently, as a large number of restaurant companies are created, as well as group meals such as school meals, the need for a large-capacity exhaust system is increasing.

In particular, large kitchens such as hotels, large malls, buildings, schools, and department stores generally prepare foods with an average of 100 people or more, resulting in a large amount of vapor.

The oil vapor is about 60 to 65 degrees, not only a dangerous factor for the worker in the kitchen, but also the worker can not work comfortably because of the warm air or unpleasant food smell.

In addition, the oil vapor generated in this way contains contaminants such as oil, and thus cannot provide a pleasant environment in the case of spreading into or out of a hotel, a large shopping mall, a building, or a building.

In addition, when the oil or the like contained in the generated steam is not filtered properly or accumulated without being cleaned, there is a risk that a fire may be generated due to hot steam or the like.

In addition, the oil vapor generated as described above has a problem in that the kitchen ceiling or the wall is damp and sticky, and provides an environment where roaches can live, but the conventional exhaust system has a problem that cleaning and maintenance are difficult.

In addition, the existing exhaust system not only can not process the steam quickly when a large amount of steam is continuously supplied, but also limited the filtering efficiency of the pollutants, it was impossible to manage hygiene.
