Preventing Odor Diffusion: An Innovative Hood Design

Abstract

This study illustrates the developmental design processes and innovative findings emerging in new products using an example aimed at producing an efficient cooker hood design that can prevent odor diffusion. Hoods used in kitchens are used to remove smoke generated during cooking. Depending on the type of food, odor—which usually diffuses away from the kitchen—adversely affects the user, thereby creating discomfort. Although this problem can be overcome using different designs of cooker hood structures, and by various flow controls, it is known that undesirable conditions persist. In this study, the smoke analysis of a current hood was conducted in an installation known as an island kitchen, and an efficient hood design was developed producing a flow effect to prevent smoke diffusion. In the innovative model, the aim was to prevent smoke diffusion by creating air curtains with reverse air channels added to the current hood. When taking the design decisions, an innovative, performance-based suction system was introduced using time-dependent analyses with the help of a CFD (Computational Fluid Dynamics) program. An ANSYS program was used during the development of this innovative hood to analyze the current hood and the validity of the results was checked by comparing both designs.
