Zusammenfassung:To provide a vehicle heater device capable of heating air to be introduced into a vehicle inner chamber without time delay when starting heating operation.SOLUTION: A heater device casing (12) includes: a heated air inflow region (14) having a heated air inflow opening (16); a heated air outflow region (22) having a heated air outflow opening (24); and a heated airflow chamber (48) through which heated air can flow in a casing inner chamber (26) surrounded by the heater device casing. Disposed in the casing inner chamber are: a combustion unit (28) to which fuel and combustion air are supplied; a combustion air fan (34) for pumping combustion air (V) to the combustion unit; a heat exchanger assembly (36) for transferring the heat provided during combustion operation to the heated air; a heated air fan (42) for pumping heated air through the heated airflow chamber; and an electrically excitable heating unit (54) for heating the heated air.SELECTED DRAWING: Figure 1 【課題】加熱運転の開始時に車両内室内に導入すべき加熱空気を時間的な遅延なく加熱することができる車両ヒータ装置を提供する。【解決手段】ヒータ装置ケーシング(12)は加熱空気流入開口(16)を備えた加熱空気流入領域(14)と加熱空気流出開口(24)を備えた加熱空気流出領域(22)とヒータ装置ケーシングによって取り囲まれるケーシング内室(26)内における加熱空気が通流可能な加熱空気流室(48)を有しており、ケーシング内室内には、燃料と燃焼空気とが供給される燃焼装置(28)と、燃焼空気(V)を燃焼装置に圧送するための燃焼空気ファン(34)と、燃焼運転時に提供される熱を加熱空気に伝達するための熱交換器アセンブリ(36)と、加熱空気流室を通して加熱空気を圧送するための加熱空気ファン(42)と、加熱空気を加熱するための、電気的に励起可能な加熱ユニット(54)が配置されている。【選択図】図1
