Description

Grease filter { GREASE FILTER OF EXHAUST HOOD }

The present invention relates to a grease filter, and more particularly, to a ventilation means installed at the top of a food cooker, which discharges contaminated air generated during the cooking process of food to the outside, but contains oil and impurities generated during the cooking process. The upper and lower parts face each other to capture moisture, suppress outdoor discharge and lower the risk of fire, and include the first and second edges, the first and second finishing materials, the first and second main guides, and the airflow inlet line. It relates to a grease filter that becomes

In general, a ventilation device installed in a kitchen makes the kitchen environment more pleasant by discharging polluted air (noxious gas) generated in the cooking process of food to the outside and introducing fresh air into the room.

These ventilation devices are equipped with a filter to remove harmful gases and a grease filter to prevent oil particles from accumulating in the duct. It is provided to discharge the purified air to the atmosphere after collection.

In addition, the grease filter collects fine oil particles generated during cooking to prevent contamination of ducts and other driving devices of the ventilation system. are disturbed and collided, so that the fine particles agglomerate and become trapped.

However, disrupting or colliding the flow of oil particles causes pressure loss in the flow field, which not only reduces the energy efficiency of the ventilation system, but also increases flow and vibration noise. It is difficult to clean, making it difficult to continuously maintain filter efficiency.

In order to solve this problem, Korean Patent Laid-Open No. 2005-0005886 has proposed a filter structure for improving collection. The problems of the prior art that are caused have not been completely solved.

In addition, as shown in FIG. 18, both side walls are respectively inserted into the openings of a plurality of lower channels and other lower channels that are opened in the upper direction and spaced apart from each other and positioned in parallel at a predetermined distance, and the upper ends of the both walls are positioned. and at least one upper channel having a closed surface vertically connecting, wherein the lower channel and the upper channel allow air introduced between the plurality of lower channels to flow along an inner side surface of a side wall of the upper channel. It is supposed to be filtered by a grease filter for ventilation equipment, characterized in that it is located apart so as to be introduced into the inside of the ventilator, but there is still a need to clean the filter from contaminants.

Here, in the conventional grease filter, polluted water generated by the entanglement of water contained in cooking gas and captured oil still exists in the grease filter, causing a problem in which bacteria and the like continue to multiply.
