A tube 36 defining the inlet 34 telescopes within the tube 50 and includes a oneway flap valve 43. The heater housing is packed with insulation 59 which is anchored by buttons 60, and is frictionally received under the wall 44 defining the container. In an alternative embodiment a container (106), Fig. 8, (not shown) has cooling fins (126) and a water reservoir (114) with tubes (108, 110) for maintaining the water level in the container (106) constant. In another embodiment a container (112), Fig. 9, (not shown) has cooling fins (116a) and a pressure relief valve (138). An inlet tube (166), Fig. 10, (not shown) is integrally formed with a dispersion plate (172) which has a plurality of 3/64 inch diameter holes in concentric and radial lines, and strengthening ribs (174). The plate (174) supports water which is separated from the water in the chamber (188) below the plate (172) by an air gap (194). The components of the humidifiers may be made from a thermoplastics material which is stable up to at least 100�F. |
