摘要
<p>The chamber has a base body (12) provided with a circumferential wall (16) and whose outline is cocoordinated with an outline of the base plate. A cover (13) is provided whose outline is cocoordinated to the outline of the base body and has a circulating fold (23) at a lower surface, and a folded fin of the fold is aligned perpendicularly to the lower surface. An air exchange device (25) is formed by a continuous air exchange opening, whose longitudinal axis is inclined from inward to outward. The air exchange device is arranged in the wall of the base body.</p>
