Disclosed is a portable radiant heating device that has a base, a radiant heat source mounted in a tiltable reflector, and a safety interlock device located in the base. The safety interlock uses a pressure-sensitive foot that prevents the heater from producing infrared heat when not in contact with a mounting surface. The safety interlock device also prevents the heater from producing infrared heat when the reflector is not tilted so as to prevent excessive amounts of infrared heat from being directed towards the mounting surface.

A full body dryer. The dryer includes a semi-circular base with a plurality of air tubes extending arcuately upward therefrom. The air tubes are extendable and retractable to adjust a height of the air tubes for use or for compact storage or transport. An upper end of each air tube of the plurality of air tubes includes an air vent to direct forced air toward a portion of an individual's body to dry the individual's body.

First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.

A system for coating removal comprises a frame having a platform extending within the frame. A plurality of heat lamps are mounted on the platform. The plurality of heat lamps are arranged to provide a heat density of at least 40 watts per square inch. A method of removing a coating is also disclosed.

Provided is a heating blower, comprising an air duct, a motor and a wind wheel arranged in the air duct, and a heating device arranged at a first air outlet of the air duct; the wind wheel is fixed to a rotating shaft of the motor; the heating device comprises a housing, an electric heater and a moving assembly; the housing is sleeved on the first air outlet, forming an inner chamber, which comprises a first area facing directly to the first air outlet and a second area not facing directly to the first air outlet; the electric heater is arranged on the moving assembly, and moves between the first area and the second area along with the moving assembly, so that an airflow blown from the first air outlet switches between a state of passing the electric heater and a state of not passing the electric heater, and is blown out from a second air outlet provided at the housing.

A portable space heater includes a housing with an air inlet through which ambient air is received and an air vent through which heated air is expelled. A centrifugal fan of the heater is configured to drive air flow into the air inlet. A flow channel of the heater is configured to direct the air flow toward the air vent and a heating element heats the air flow in the flow channel. The heater additionally includes a sensor configured to sense proximity of a body part to the air vent and a controller configured to pause operation of the heating element based on the sensing, wherein the centrifugal fan, the flow channel, the heating element, the sensor and the controller are housed in the housing.

There is provided a generator system for generating power and heat. The system comprises an engine, an electrical power generator driven by the engine, a radiator for cooling engine coolant, a heater powered by the electrical power generator, and an airflow generation device driven by the engine. The heater has an airflow outlet and an airflow inlet. The airflow generation device has an air intake inlet and an air exhaust outlet. The system further comprises a first conduit directing airflow through the radiator into the air intake inlet of the airflow generation device. The system also includes a second conduit directing airflow from the air exhaust outlet of the airflow generation device to the airflow inlet of the heater. The airflow generation device may be a centrifugal fan that draws air through the radiator and pushes the air through the heater.

A system for coating removal comprises a frame having a platform extending within the frame. A plurality of heat lamps are mounted on the platform. The plurality of heat lamps are arranged to provide a heat density of at least 40 watts per square inch. A method of removing a coating is also disclosed.

First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.

A portable space heater is provided having a heating assembly that includes at least one heating element positioned in front of a fan (defined by the direction of the air flow with the air blowing toward the front) such that the heating element is in linear alignment with the fan along the axis of rotation of the fan. The fan and the at least one heating element may be further positioned within a duct assembly that narrows as it approaches a front grill of the portable space heater.
