Title: Hot air space heater
Inventor: YAMAZAKI YASUSHI
IPC: F24H3/02
Filed: 1987-05-01
Abstract: PURPOSE:To make it possible to perform uniform room heating at the time of the low capacity operation by holding the strength of discharging hot air at the strength of discharging of one rank higher even if the amount of combustion is switched to 'small' and at the same time discharging hot air intermittently so that the average calorie in the discharged air is a calorie which is specified for the low capacity operation. CONSTITUTION:The amount of fuel supply and the air supply for combustion are switched in three steps in response to the strong, medium and weak operations in three steps and the amount of combustion is changed over among three steps, large, medium, and small. For the three-step switchings for the room heating capability the switching of the strength of discharging air by a fan 6 is in two steps, large and medium. Namely following the switching of the room heating capability, if the amount of combustion is switched from large to medium, the amount of discharge by the fan 6 is changed from large to medium, but the strength of discharging hot air is maintained at medium. When the room heating capability is 'weak' and the amount of combustion is small, the strength of discharging hot air is in the state of medium, and, on the other hand, the discharge is intermittent. The fan 6 for discharging hot air is changed for its rotational speed in two steps, large and medium by a control section 10 following the switching operation of the room heating capability.
