By the way, in the above-described kitchen ventilation equipment, contaminants generated due to the heat source for cooking (for example, dust such as smoke caused by cooking by the heat source for cooking, Mist-like oil, steam, etc.) and bad odors are sucked into the ventilation hood and exhausted to the outside, but some of the pollutants and bad odors are indoors such as in the kitchen where the kitchen stand is installed. And then the room is contaminated.

In addition, in the layout of the apartment,
There is a case where the room where the kitchen stand is installed is placed in a place where it does not contact the outside (for example, the case where the room is placed in the center). Duct construction is required to remove pollutants and odors to the outside, and this duct construction hinders space saving, shortened construction period, and reduced construction costs.

Therefore, the inventor of the present invention uses an air curtain to block outflow of pollutants and offensive odors caused by the cooking heat source of the kitchen stand, and sucks and purifies air containing the pollutants and offensive odors. Then, the ventilation equipment for the kitchen used as the air of the air curtain was proposed.

According to the kitchen ventilation equipment proposed by the present inventor, the air curtain prevents the outflow of pollutants and malodors in the air caused by the heat source for cooking, etc. The environment can be significantly improved.
