Description

Kitchen Ventilation System

The present disclosure relates to a kitchen ventilation system, and more particularly, to a kitchen ventilation system capable of physically and chemically removing oil particles generated during food cooking.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and inclusion in this section is not an admission that it is prior art.

In a kitchen in a general home or restaurant, a ventilation system is installed to remove gas, smoke, or oil vapor generated during cooking. The ventilation system is configured to discharge gas or oil vapor generated by installing a ventilation fan or exhaust duct to the outside, but the ventilation fan or exhaust duct does not have a function to remove oil components or contaminants contained in the gas or oil vapor. It is deposited inside the ventilation system to form deposits, which causes problems.

For example, a heating appliance such as a gas range or induction is used to cook food. During cooking, a spark is generated in a place where a flame or oil vapor in the duct is deposited, resulting in a fire risk. In addition, as oil is deposited on a ventilation fan or exhaust duct, mold or bacteria are generated, resulting in problems in hygiene or health of people working in the kitchen. In addition, work efficiency may be reduced due to odors generated from oil deposits, and additional costs or efforts are incurred due to periodic cleaning to remove deposits deposited in the exhaust duct.

A technique for preventing oil deposition by installing a grease filter inside the exhaust duct to remove the oil component is known. In one embodiment, in Korean Patent Registration No. 10-1540546, the filter efficiency including front and rear plates having front and rear suction parts extended to have a bent part between the vents for sucking odors or smoke generated in the kitchen is shown. Disclosed is an excellent vertical exhaust type grease filter. However, the grease filter has a disadvantage in that the oil collection efficiency is quite low, and as a result, oil particles are steadily deposited inside the grease filter, thereby contaminating the exhaust duct or the ventilation fan.
