    • An inner shell is incorporated within an outer shell and is of smaller dimensions to provide side spaces for the upward flow of heat, a top space communicating with an outlet, and a rear space having a V-shaped baffle therein causing upward flow of heat in the rearward area to be circulated and slowed for increased heating efficiency. An extension is attachable to the baffle for extending it upwardly and forwardly to control the flow of heat at the baffle. The inner shell has an imperforate tray extending from side to side and arranged to be moved forwardly through an opening in the inner shell and providing a natural forced flow of heat around it from the bottom for heating room areas.
    • 内壳结合在外壳中并且具有较小的尺寸以提供用于向上的热流的侧空间,与出口连通的顶部空间以及具有V形挡板的后部空间,其中引起向上的热流 要循环和减慢的后部区域以提高加热效率。 延伸件可附接到挡板上,用于向上和向前延伸以控制挡板上的热量流动。 内壳具有从一侧延伸到另一侧并且被布置成向前移动穿过内壳中的开口的无孔托盘,并且从底部向其提供自然的强制流动热量,用于加热房间区域。
