Abstract
A heating element for use in a portable humidifier is provided, which is at least partially disposed within a tray of water within the humidifier. The heating element includes a mounting portion, a leg portion and a foot portion. The mounting portion is coupled to the housing and an tipper end of the leg portion, which extends vertically downward from the mounting portion. The foot portion is coupled to a lower end of the leg portion, and extends horizontally therefrom. The leg portion is elongated and separates the mounting portion and the foot portion. The foot portion is shaped such that a line from the upper surface to the lower surface must pass through a perimeter of the heating element when viewed from above. A bottom surface of the foot portion is curved or slanted upward from a nadir to the perimeter of the heating element.
