Abstract
An electric toaster has heating elements, at least one toast well into which the toast is fed through a loading and unloading opening, and a multi-walled housing. The multiple housing walls are separated from one another and form a meander-shaped flow channel for an air stream introduced from outside. An air stream enters the flow channel through an air inlet opening and cools the outer walls of the housing by convection as it passes through the meander-shaped flow channel and emerges through an air outlet opening into the toast wall. The meander-shaped flow channel includes reversing curve portions located in top and bottom areas of the meander-shaped flow channel structure such that the air stream flows in an upward direction in one portion and in a downward direction in another portion of the meander-shaped flow channel.
