PROBLEM TO BE SOLVED: To provide a vehicular heating device capable of effectively using radiant heat radiated from a radiation heater and thus contributing to power saving during heating operation.SOLUTION: A vehicular heating device 1 includes: a radiation heater having an armrest heater 10A and a rear heater; and a seat air-conditioning device 20. The armrest heater 10A includes: a radiation body 11 emitting radiant heat RH; and a radiant heat recovery member 15 disposed on a second surface side of the radiation body 11 and constituted by a material having high thermal conductivity. The armrest heater 10A is disposed to make the radiant heat recovery member 15 come into contact with a side surface on a seating surface 51 side of an armrest duct 22 of a front side seat. The radiant heat RH from a first surface side of the armrest heater 10A warms a portion around legs of an occupant seated on the front side seat. The radiant heat RH on a second surface side of the armrest heater 10A is recovered by the radiant heat recovery member 15, is transmitted to blowing air B blown in the armrest duct 22 and is used for heating inside of a cabin.SELECTED DRAWING: Figure 4
【課題】輻射ヒータから放射される輻射熱を有効活用し、暖房運転時の省動力化に貢献可能な車両用暖房装置を提供する。【解決手段】車両用暖房装置1は、肘掛ヒータ10A、後部ヒータを含む輻射ヒータと、シート空調装置20とを有している。肘掛ヒータ10Aは、輻射熱RHを発する輻射体11と、輻射体11の第2面側に配置され、高い熱伝導性を有する材料で構成された輻射熱回収部材15とを有している。肘掛ヒータ10Aは、前側座席の肘掛ダクト22における座面51側の側面に対して、輻射熱回収部材15を接触させて配置される。肘掛ヒータ10Aの第1面側からの輻射熱RHは、前側座席に座っている乗員の脚部周辺を暖める。肘掛ヒータ10Aの第2面側の輻射熱RHは、輻射熱回収部材15によって回収され、肘掛ダクト22を送風される送風空気Bに伝達されて、車室内の暖房に用いられる。【選択図】図4
