Description

Pollutant Removal Module in Oven and Pollutant Removal Method in Oven Using the Same The present invention relates to a contaminant treatment module for an oven and a method for treating contaminants in an oven using the same. For example, the present invention relates to a system for treating oil mist and odors generated during the cooking process inside an oven. Harmful substances that naturally occur through cooking include acrylamide and benzopyrene. Acrylamide is a substance produced by the chemical reaction between aspartic acid and sugar when carbohydrate-rich foods are cooked at high temperatures, and its production tends to increase with temperature and time when starchy foods such as potatoes and grains are heated at high temperatures. Benzopyrene is known to be produced by the incomplete combustion of organic matter during the process of high-temperature treatment of food. In addition, frying emissions from high-temperature or cooking oil fume (COF) are potentially carcinogenic substances. These COFs are a complex of particulate matter and gaseous substances, including oil particles, thermal decomposition products of oil, and ultrafine particles generated from the incomplete combustion of food ingredients and spices. Representative thermal decomposition products of oil include aldehydes, such as formaldehyde and acrolein, which are causative agents of nasopharyngeal cancer and leukemia. In addition, because various sauces and spices are used during cooking, one may be exposed to diacetyl, which causes diseases such as asthma, bronchiolitis obstruction, and COPD. As such, during the cooking process, one may be exposed to harmful gaseous substances such as acrolein, formaldehyde, and diacetyl along with particulate matter. Furthermore, it is estimated that fine dust in indoor spaces is increasing due to the use of cooking appliances such as gas stoves, grills, and ovens. However, conventional cooking appliances such as ovens have not been able to provide a function to remove contaminants such as oil mist and odors generated during the cooking process, and accordingly, there is a need to develop an oven contaminant treatment module that can be efficiently operated with a simple structure and low energy. The technology forming the background of this invention is disclosed in Korean Registered Patent Publication No. 10-2294377.
