Description

Kitchen Hood Filter System {Kitchen Hood Filter System}

The present invention relates to a kitchen hood filter system, and more particularly, to a kitchen hood filter system implemented to enable installation of a detachable filter.

In general, an exhaust hood has been installed on the upper part of a combustion appliance for cooking in a kitchen to smoothly exhaust a mixed gas of oil-containing steam generated in the cooking process and exhaust gas discharged from the combustion appliance. The exhaust hood includes a main body communicating with an exhaust duct installed on the ceiling and a non-woven fabric filter disposed inside the main body.

However, such a conventional exhaust hood has problems in that oil or foreign substances contained in the exhaust adhere to the filter, resulting in poor appearance, deterioration of the filter effect, cumbersome maintenance such as the need to replace the filter, and increased maintenance cost. However, since the filter was not fixed, there was a problem in that the filter fluctuated inside the housing due to the blowing pressure and dust or foreign substances fell.

The kitchen hood is a device to prevent indoor contamination by smell by inhaling heat and odor generated in the process of cooking food using a gas stove and discharging it to the outdoors. Currently, kitchen hoods in restaurants and the like have a tubular structure and are inconvenient to manage.

Filters installed in conventional kitchen hoods have to be separated from the housing and washed individually when contaminated, and in food service establishments, there is a problem in that there is difficulty in managing the overall system such as filters and duct assemblies because frequent cleaning is required due to the short service life of filters. .

On the other hand, the above-mentioned background art is technical information that the inventor possessed for derivation of the present invention or acquired in the process of derivation of the present invention, and cannot necessarily be said to be known art disclosed to the general public prior to filing the present invention. .
