A heat storage device () of the present disclosure includes: a heat storage container () having an inlet () and an outlet () for a heat medium; a plate-like heat storage body () disposed in the heat storage container () and having a heat storage material () and an envelope () containing the heat storage material (); a plate-like spacer () placed on the heat storage body () in the heat storage container () and having a plurality of contact portions () that are in contact with the heat storage body () and a plurality of non-contact portions () that are spaced from the heat storage body (), the contact portions () and the non-contact portions () being alternately formed in a specific direction; and a plurality of flow paths () for leading the heat medium from the inlet () to the outlet (), the flow paths being formed by a surface of the heat storage body () and the non-contact portions () and extending in a direction intersecting the specific direction. Thereby, the heat transfer characteristics between the heat storage material and the heat medium are good.

Heat storage device

A vehicle heating apparatus is a heating apparatus to be mounted on or built in a vehicle seat at a position below a sitting portion of the vehicle seat. The vehicle heating apparatus includes: a housing having an intake port, a blowing port, and an internal space serving as a flow path of air from the intake port to the blowing port; a fan provided in the internal space of the housing; and a heater provided in the internal space of the housing. In a usage state where the vehicle heating apparatus is mounted on or built in the vehicle seat, the blowing port is located above the intake port and opens downwardly with respect to a horizontal direction. Thereby, the amount of heating required for the heater is further reduced.

Vehicle heating apparatus and heater-equipped vehicle seat

A vehicle heating apparatus () to be mounted on or built in a vehicle seat () at a location below a sitting portion S of the vehicle seat () includes a housing (), a fan (), and a heater (). The housing () has an intake port (), a left nozzle (), a right nozzle (), an air curtain nozzle (), and an internal space () serving as air flow paths from the intake port () to the left nozzle (), to the right nozzle (), and to the air curtain nozzle (). The air curtain nozzle () is located between the left nozzle () and the right nozzle (), and is formed so as to, in the usage state, blow air delivered by the fan () in a direction inclined upward at an angle of not more than 90&#xb0; to a direction in which warm wind is blown out of the left nozzle () and the right nozzle ().

A vehicle heating apparatus (A) of the present disclosure is a heating apparatus to be mounted on a vehicle seat () at a position below a sitting portion (S) of the vehicle seat (). The vehicle heating apparatus (A) includes: a housing () having an intake port (), a blowing port (), and an internal space () serving as a flow path of air from the intake port () to the blowing port (); a fan () provided in the internal space (); a heater () provided in the internal space (); and a mounting structure () adapted to mount the housing () to the vehicle seat () in such a manner that the housing () is movable in a width direction of the vehicle seat (). Therefore, the vehicle heating apparatus (A) of the present disclosure is highly convenient for occupants.
