ータの空焚き防止装置。 −A heating chamber is formed inside by a body and a housing attached to the body, and the body has an inlet passage whose inlet side is connected to an air source and whose outlet side is open to the heating chamber, and whose inlet side is open to the heating chamber and whose outlet side is connected to the heated air source. The equipment used is provided with five consecutive outflow passages, and the body includes an inflow pipe whose one end is connected to the outflow side opening of the front inflow passage, extends inside the heating chamber, and whose other end opens at the bottom of the housing. A heating heater is provided in the heating chamber and around the inflow pipe, and the body further includes a thermoswitch' and a temperature fuse that operate by detecting the temperature in the outflow passage. In an air heater in which the heat source, thermoswitch, and temperature fuse are connected to the power source as a series circuit, a core pressure number is installed in the air system path between the air source and the equipment using heated air. A device for preventing dry heating of an air heater, characterized in that a pressure detection switch mechanism for detecting pressure is provided, and a switch of the pressure detection switch mechanism is inserted in the middle of the series circuit. −
