Humidifier and layered heating element

摘要

A heating apparatus (36) includes a heating element (48) which converts electrical power to heat energy, a heatable element (44) having a first surface and a second surface, and a dielectric laminate layer (46) between the heating element and the first surface of the heatable element. The dielectric laminate layer is thermally conductive to transfer heat energy from the heating element to the heatable element. The second surface of the heatable element is configured heat a liquid in a container. The heating apparatus is assembled using an automated assembly process. The heating apparatus is typically used in a humidifier.
