That is, according to the present embodiment, the heater 15 does not exist in a portion upstream of the fan 14 in the air flow path 13. According to such a configuration, the pressure loss of the flow in the air flow path 13 upstream of the fan 14 is reduced, so that the suction force of the fan 14 is suppressed from decreasing. Further, since the heater 15 is located in a portion of the air flow path 13 on the downstream side of the fan 14, the air flow path 13 between the left heater 15l and the left nozzle 12l or between the right heater 15r and the right nozzle 12r.

- the air flow rate of the fan 14 is, for example, 1.8 to 15 m 3 / hour. According to this, the circulating airflow of warm air like the circulating airflows F1 and F2 is likely to be formed.
- the heater 15 is an electric heater such as a PTC (Positive Temperature Coefficient) heater or a ceramic heater. In this case, the heater 15 generates heat by receiving power supply from a power source (not shown) and heats the air flowing toward the left nozzle 12l or the right nozzle 12r.
- the output of the heater 15 is not particularly limited, but is 50 to 300 W, for example.
- the heater 15 may be a hot water heater that heats with a coolant that exchanges heat with an external heat source (for example, a water-cooled engine) of the vehicle heating device 10a.
- the angle ⁇ between the normal A and the horizontal plane H is not particularly limited as long as it exceeds 0 ° and is less than 90 °.
- the angle ⁇ is, for example, 30 ° to 70 °.
- the warm air blown from the left nozzle 12l and the right nozzle 12r tends to flow along the occupant's lower leg, and the warm air easily reaches the intake port 11. For this reason, it is easy to achieve both easy reach of the warm air to the air inlet 11 and securing of a warm feeling in the occupant's lower leg.
- the angle ⁇ is desirably in the range of 35 ° to 60 °, and more desirably in the range of 40 ° to 50 °.
- the angle ⁇ formed between the normal B and the normal A is not particularly limited as long as it exceeds 0 ° and is within 90 °.
- the angle ⁇ is preferably determined so that the air curtain airflow F4 is formed below the lower surface 30b of the instrument panel 30 of the vehicle (vehicle). Thereby, it can suppress effectively that a warm air raises by the air curtain airflow F4. Further, it is desirable that the angle ⁇ is determined so that the air curtain airflow F4 is formed upward from the position where the passenger's foot is placed. Thereby, the thermal sensation around the occupant's toes can be effectively enhanced.
- the air curtain nozzle 12c may be formed so that, for example, air is blown out in a substantially horizontal direction or below the horizontal direction in a use state.

前記エアカーテンノズルは、前記左ノズルと前記右ノズルとの間に位置し、前記使用状態において、前記左ノズル及び前記右ノズルからの前記温風の吹出方向に対して上方に90°以内の角度で傾いた方向に、前記ファンによって送り出された空気を吹出すように形成されている、乗物用暖房装置を提供する。
乗物用シートと、
前記乗物用シートの座部より下方で前記乗物用シートに装着又は内蔵されている第1態様~第8態様のいずれか1つの乗物用暖房装置と、を備える暖房付き乗物用シートを提供する。
図1に示す通り、暖房付き乗物用シート1aは、座面クッション2a、背面クッション2b、及びヘッドレスト2cを有する乗物用シート2と、乗物用暖房装置10aとを備えている。暖房付き乗物用シート1aは、乗物の床面に設けられたベース部材3に取り付けられている。座面クッション2aは、乗員の上腿を支持する座部Sを形成している。背面クッション2bは、乗員の背面を支持する。乗物用暖房装置10aは、座部Sより下方で乗物用シート2に装着されている。すなわち、暖房付き乗物用シート1aは、乗物用シート2と、乗物用シート2の座部Sより下方で乗物用シート2に装着されている乗物用暖房装置10aを備えている。乗物用暖房装置10aは、乗物用シート2の前方(X軸正方向)の端部に設けられており、主として乗員の下腿に温風を供給する。なお、添付の図面において、XY平面が水平である。暖房付き乗物用シート1aの前方をX軸の正方向とする。また、暖房付き乗物用シート1aの幅方向をY方向とし、乗員の右足から左足に向かう方向をY軸の正方向とする。また、Z軸は、XY平面に垂直であり、Z軸方向が鉛直方向である。本明細書において「左」及び「右」は、暖房付き乗物用シート1aに着座する乗員を基準にして定めている。
次に、本開示の第2実施形態に係る乗物用暖房装置10bについて説明する。なお、特に説明する場合を除き、第2実施形態は第1実施形態と同様に構成される。第1実施形態と同一または対応する第2実施形態の構成要素には、第1実施形態と同一の符号を付し、詳細な説明を省略することがある。すなわち、第1実施形態に関する説明は、技術的に矛盾しない限り、本実施形態にも適用されうる。このことは、後述する実施形態ついても同様である。
次に、第3実施形態に係る乗物用暖房装置10cについて説明する。図7に示す通り、乗物用暖房装置10cにおいては、筐体20の内部空間13にファン14が1つだけ設けられている。吸気口11は、左ノズル12l、右ノズル12r、及びエアカーテンノズル12cに供給されるべき空気を吸込むための共通吸気口11uとして形成されている。乗物用暖房装置10cは、分流部材16をさらに備えている。分流部材16は、内部空間13における空気の流れ方向のファン14より下流側に設けられている。分流部材16は、左ノズル12l、右ノズル12r、及びエアカーテンノズル12cのそれぞれに向かって流れる空気の量を調整する。分流部材16は、例えば、複数の通気孔が形成された板状の部材である。左ノズル12l、右ノズル12r、及びエアカーテンノズル12cから吹出される空気の流れの流速に過不足がないように板状の部材の任意の領域における通気孔の開口面積及び通気孔の数等が定められている。
次に、第4実施形態に係る乗物用暖房装置10dについて説明する。図8に示す通り、使用状態の乗物用暖房装置10dにおいて、エアカーテンノズル12cは、エアカーテンノズル12cにおける内部空間13の乗物用シート2の幅方向(Y軸方向)の長さがエアカーテンノズル12cの開口Pcに近づくに従って増加するように形成されている。すなわち、使用状態の乗物用暖房装置10dを平面視したときに、エアカーテンノズル12cのY軸方向の端部は、水平面(XY平面)におけるX軸に平行な直線Cに対して角度γだけ傾斜している。これにより、乗物用シート2の幅方向に拡がるように、エアカーテンノズル12cから空気が吹出される。その結果、左ノズル12l及び右ノズル12rによって吹出された温風が上昇することを広い範囲で抑制できる。
次に、第5実施形態に係る乗物用暖房装置10eについて説明する。図9に示す通り、乗物用暖房装置10eにおいて、筐体20の内部空間13は、仕切板17によって仕切られている。使用状態において、仕切板17は左ヒータ15lの右端から筐体20の中央に向かって上方に延びている。また、仕切板17は、右ヒータ15rの左端から筐体20の中央に向かって上方に延びている。左ヒータ15lの右端から延びている仕切板17と右ヒータ15rの左端から延びている仕切板17とは内部空間13の中央で接続している。すなわち、仕切板17は、左ヒータ15lの右端と右ヒータ15rの左端とを接続し使用状態における筐体20の上方に向かって突出したV字状の形状を有している。これにより、左ヒータ15lを通過した温風の一部はエアカーテンノズル12cから吹出され、右ヒータ15rを通過した温風の一部はエアカーテンノズル12cから吹出される。ヒータ15を通過した温風がエアカーテンノズル12cから吹出されるので、エアカーテンノズル12cから吹出される空気の温度が高い。このため、エアカーテンノズル12cから吹出された温風によって乗員のつま先周辺を温めることができる。
次に、第6実施形態に係る乗物用暖房装置10fについて説明する。図10Aに示す通り、乗物用暖房装置10fは、エアカーテンノズル12cの開口を開閉する開閉構造18を備えている。開閉構造18は、エアカーテンノズル12cの開口が閉じられる位置と開口が開かれる位置とを往復動するパネル18aを含む。具体的に、開閉構造18は、複数のパネル18aと、つまみ18bと、リンク18cとを含んでいる。複数のパネル18aは、エアカーテンノズル12cの幅方向(Y軸方向)に並んでおり、エアカーテンノズル12cの開口近傍においてエアカーテンノズル12cの内周面に軸支されている。それぞれのパネル18aは、複数のパネル18aが並んでいる方向に揺動可能にエアカーテンノズル12cの内周面に軸支されている。リンク18cは、複数のパネル18aを互いに連結している。これにより、いずれか1つのパネル18aの揺動に連動して他のパネル18aが揺動する。それぞれのパネル18aは、複数のパネル18aが並んでいる方向に他のパネル18aを平行移動させた姿勢をとる。
