VEHICLE SAFETY DEVICE

摘要

A vehicle safety device installed in a hybrid electric vehicle or an electric vehicle is provided to be capable of interrupting a current supplied from a power supply to a load via a supply line. The vehicle safety device includes first interrupting mechanism adapted to set the supply line in an interrupted condition when a temperature of the load reaches a first set temperature and second interrupting mechanism adapted to set the supply line in the interrupted condition such that the supply line cannot be returned to an energized condition when the temperature of the load reaches a second set temperature that is higher than the first set temperature.

主权项

1. A water-heating device installed in a hybrid electric vehicle or an electric vehicle, the water-heating device being configured to heat water as a refrigerant, the water-heating device comprising:
a warm water tank including a supply passage and an exhaust passage, the refrigerant being supplied through the supply passage and discharged through the exhaust passage; an electric heater housed in the warm water tank; a supply line configured to supply a current to the electric heater from a power supply; and an interrupting system including a heat detector, the heat detector being configured to detect heat from the electric heater, the interrupting system being configured to set the supply line in an interrupted condition when a temperature of the electric heater reaches a set temperature, wherein the heat detector is in contact with the electric heater at a position in the warm water tank, the position being closer to the supply passage than the exhaust passage.
