Title
(EN) Induction cooking apparatus having cooling arrangement therefor
Abstract
(EN)

An induction cooking apparatus having a plurality of induction heating coils disposed in an array for induction-heating a metallic heating load by electromagnetic induction. Air inlet ports are formed at the front end of the appliance to admit cooling air for cooling the interior of the cooking appliance and air outlet ports are formed at the rear end of the appliance. The apparatus ensures comfortable cooking without exposing the user to hot exhaust air and, also, better cooling without drawing in hot exhaust air or hot steam from the food materials. Furthermore, a partition is provided within the appliance for separating the power converter unit from the operating unit for blocking objectionable movement of cooling air and blocking induction radiation from the power converter unit so as to protect the operating unit from the induction radiation from the power converter unit and prevent faulty operation thereof, and a cooling fan is disposed in an orifice in the partition for circulating cooling air within the appliance and ensuring an efficient cooling performance.
