Abstract
A water distiller has a steam chamber that includes a tray for containing water to be distilled. Water is conveyed from a source to the tray for distillation. A valve operates in an open position to convey water to the tray and a closed position to block the passage of water to the tray. A heating element means extends in the steam chamber for submersion in the water carried by the tray. The heating element is operable within a range of temperatures to heat the water in the tray. The heating element includes a main body portion having an axis that extends in a plane generally parallel to the water in the tray and a section havign an axis that is deflected above the axis of the main body portion. A heat sink surrounds the deflected section of the heating element means. A heat sensor detects the temperature of the heat sink. A control connects the valve and the heat sensor means. The control closes the valve when the sensed temperature of the heat sink is equal to or less than a predetermined amount. The control opens the valve when the sensed temperature of the heat sink is greater than the predetermined temperature.
