Title: Hot air heater
Inventor: MASUKO YOSHIO
IPC: F24C3/00
Filed: 1983-10-07
Abstract: PURPOSE:To eliminate the influence of blast from a fan at firing and to improve firing property, by a method wherein a fan, which serves to feed out a combustion heat from a burner to the interior of a room through a hot air supply port, is rotated through utilization of a change in the shape of a shape memory alloy due to the heat. CONSTITUTION:When combustion is started, a main drying pulley 17, located in the vicinity of a flame port part 3 of a burner 1, is heated by a combustion heat and is increased in temperature, while a belt 18 formed of a shape memory alloy is partially heated. In the belt 18, a change in a shape is produced due to a heat, a stress, produced due to the change in a shape, is exerted as a rotation force upon a main driving pulley 17, and the rotation force is transferred to a driven pulley through the belt 18. With a fan 15 driven, blast is supplied into a wind tunnel 2, and a combustion heat, which rises from the burner 1 within the wind tunnel 2, is forcibly supplied through a hot air supply port 10 to the interior of a room. This prevents the fan 15 from being driven simultaneously with firing and enables the fan 15 to be driven with a slight delay, and as a result, there is no fear of failure in firing based on the influence of blast from the fan 15 at firing.
