#CMT# #/CMT# Device has a switch (6) selectively moved between a configuration, in which electric heating units (4) are powered and a configuration, in which electric power supplied to the units is cut off. A ring shape thermally-fusible part (7) partially fuses when an area (8) of the units exceeds a critical temperature threshold and moves the switch (6) from the power supply configuration to the power cut-off configuration. The part is made up of an electrically non-conducting plastic material. The switch has a connection terminal formed on an outer surface (12) of a complementary element (3). #CMT#USE : #/CMT# Used for electrical heating of a fluid. #CMT#ADVANTAGE : #/CMT# Combination of the switch and the fusible part permits to have a free power cut-off and to detect the passage of reliable critical temperature threshold. The connection terminal is formed directly on the complementary element, thus simplifying the connection of the switch with heating units, suppressing the necessity of a connecting cable between the terminal and the heating units, and facilitating the assembling operations of the device by reducing the number of parts necessary for its fabrication. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a fluid-heating device with its switches in power supply configuration and with the fusible part. 3 : Complementary element 4 : Electrical heating units 6 : Switch 7 : Ring shape thermally-fusible part 8 : Area 12 : Outer surface. |
