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.
