Abstract
A heating device includes an elongated heater, a first holding member configured to hold the heater, a power shut-off member configured to shut off power supply to the heater, a second holding member configured to hold the power shut-off member, a first urging member configured to press the power shut-off member against the heater, and a regulation member configured to regulate a position of the second holding member, wherein, in a longitudinal direction of the heater, one end side of the second holding member is urged by the first urging member, and another end side of the second holding member is regulated in position by the regulation member.
Claims16
A heating device comprising:
- a heater that is elongated;
- a first holding member configured to hold the heater;
- a power shut-off member configured to shut off power supply to the heater;
- a second holding member configured to hold the power shut-off member;
- a first urging member provided on one end side of the second holding member in a longitudinal direction of the heater;
- and
- a regulation member provided on another end side of the second holding member,
- wherein, in the longitudinal direction of the heater, the one end side of the second holding member is urged by the first urging member, and the other end side of the second holding member is regulated in position by the regulation member such that the second holding member turns about the regulation member to press and stably abut the power shut-off member against the heater.
A heating device comprising:
- a heater that is elongated;
- a first holding member configured to hold the heater;
- a temperature detection member configured to detect a temperature;
- a second holding member configured to hold the temperature detection member;
- an urging member provided on one end side of the second holding member in a longitudinal direction of the heater;
- and
- a regulation member provided on another end side of the second holding member,
- wherein, in the longitudinal direction of the heater, the one end side of the second holding member is urged by the urging member, and the other end side of the second holding member is regulated in position by the regulation member such that the second holding member turns about the regulation member to press and stably abut the temperature detection member against the heater.
A heating device comprising:
- a frame member;
- a heater that is elongated and configured to generate heat;
- a heater holder configured to hold the heater;
- a thermostat having an abutting portion;
- a thermostat holder configured to hold the thermostat and having a fulcrum at one end side of the thermostat holder where the fulcrum is fixed to the frame member;
- and
- a thermostat spring positioned between another end side of the thermostat holder and the frame member,
- wherein, as the thermostat spring presses against the thermostat holder, the thermostat holder turns about the fulcrum to press and stably abut the abutting portion of the thermostat against the heater as an electric contact configured to shut off power to the heater based on heat generated by heater without urging the both sides of the thermostat by springs.
