<p>The cabinet (1), fitted with several boards (10, 11, 12), has two lateral panels (3, 4), a bottom panel (5), a top unit (6) and two hinged doors (7, 8). The top unit is designed as a box-shaped housing (14) containing a fanning device for moving fresh air into the housing (14) and can additionally be equipped with a heating arrangement. The fresh air is guided through small ducts (17, 18, 19, 20) into the space between the outer panel and the inner lining (50) of each of the doors (7, 8) and from there into the cabinet (1) through a multitude of holes (22).
