HOT AIR HEATING DEVICE

PROBLEM TO BE SOLVED: To provide a heating device capable of performing a heating operation in which some advantages of each of several heating units can be utilized in maximum degree when the heating units are operated simultaneously without performing data communication among the heating units.SOLUTION: This invention relates to a hot air heating device having a parallel usage operation mode for selecting it when it is applied together with another heating device in addition to a normal operation mode for setting a heating output in reference to a set temperature and a room temperature. When the parallel usage operation mode is selected, if the room temperature reaches a first predetermined temperature lower than the set temperature, a heating operation is carried out with this first predetermined temperature being applied as a target room temperature, and after this operation, if the room temperature reaches a second predetermined temperature, heat generating means is stopped in its operation and the heating operation is stopped. With this arrangement as above, at the time of starting operation, the room temperature is rapidly increased by the heating capability of the hot air heating device and after increasing the room temperature to a certain degree, the heating output of the hot air heating device is reduced and the heating capability of other heating units is utilized.SELECTED DRAWING: Figure 3 【課題】暖房器具間でデータの通信を行うことなく、かつ複数の暖房器具を併用して運転した際に夫々の持つ利点を最大限活用できるような暖房運転を行うことのできる暖房装置を提供すること。【解決手段】設定温度と室温から暖房出力を設定する通常運転モードのほかに、他の暖房器具と併用して使用する際に選択する併用運転モードを備えた温風暖房装置であって、併用運転モードが選択された際には、運転を開始後、室温が設定温度よりも低い第１所定温度に到達すると、この第１所定温度を目標室温として暖房運転を行い、その後室温が第２所定温度に到達すると熱発生手段を停止して暖房運転を停止する。これにより、運転開始時には温風暖房装置の暖房能力によって室温をすばやく上昇させ、ある程度室温が上昇した後は、温風暖房装置の暖房出力を低下させて他の暖房器具の暖房能力を活用する。【選択図】図３
