Abstract

A smart hood system for a cooking room is provided, capable of purifying cooking fumes generated from cooking appliances indoors using a bio-hood device and a dust collector without external discharge. This smart hood system for a cooking room comprises: a hood positioned above the cooking appliance to collect cooking fumes; an intake pipe section installed below the hood to suck in the cooking fumes collected by the hood; a dust collector that charges and captures dust particles among the cooking fumes introduced from the intake pipe section for purification; and an exhaust pipe section positioned on the side of the cooking appliance to discharge purified air, purified by the dust collector, upward toward the hood. Here, the purified air discharged upward through the exhaust pipe section flows into the hood to form an air curtain.

Description

Smart hood system for kitchen The present invention relates to a smart hood system for a kitchen, and more specifically, to a smart hood system for a kitchen that can purify cooking fumes generated from cooking appliances indoors using a bio-hood device and a dust collection device without external discharge. According to the Korea Occupational Safety and Health Agency, as of 2018, the number of workers in the food service industry reached approximately 1.05 million, with vulnerable groups, primarily women in their 40s and 50s, working as food service cooks. Recently, the death of a food service worker from lung cancer has raised concerns regarding lung diseases among food service cooks, and in February 2021, the Korea Workers' Compensation and Welfare Service recognized this as an industrial accident. The International Agency for Research on Cancer (IARC) has classified cooking fumes from oil-based cooking processes as potentially carcinogenic substances, and poor working conditions in cooking, such as the occurrence of carbon monoxide poisoning accidents, are becoming a social issue. Cooking fumes are smoke generated when biological proteins burn or various components decompose during deep-frying using high-temperature oil; they contain various harmful substances and, from an industrial hygiene perspective, are defined as ultrafine solid particles created by the cooling of hot oil vapors. Currently, the method for handling cooking fumes in kitchens follows a concentrated external exhaust system via a main duct. Specifically, a main duct is connected to a hood located above the cooking equipment to discharge cooking fumes to the outside; after discharge, the fumes are either purified by a dust collector outside the building or diffused into the atmosphere without a separate treatment process. Since external exhaust ducts are not subject to environmental regulatory monitoring, most food service facilities evade environmental standards by reducing pollutant concentrations through diffusion dilution via atmospheric release, without equipping them with separate dust collectors. Consequently, when atmospheric diffusion is insufficient due to atmospheric pressure or wind conditions, it becomes a subject of complaints from nearby residents. Because current cooking fume treatment methods focus solely on reducing the concentration of pollutants within the kitchen, they run counter to the national goal of reducing the total emissions of air pollutants or greenhouse gases in the urban environment.
