In-vehicle heating device

Abstract

An in-vehicle heating device according to the present invention is provided on a lower part of a front side of a seat cushion ( 31 ) serving as a seating unit of a vehicle seat ( 30 ). The in-vehicle heating device includes: an air feeder ( 11 ) including a suction opening ( 11 a ) through which external air is sucked into the air feeder ( 11 ); a warm air generator ( 12 ) including a heater ( 22 ) therein, the warm air generator ( 12 ) being configured to heat air fed from the air feeder ( 11 ) to generate warm air; and a blow-out unit configured to blow out the warm air from the warm air generator ( 12 ), such that the warm air is blown out forward of the seat cushion ( 31 ). At least a part of the blow-out unit is positioned at a front of the seat cushion ( 31 ), and doubles as a front shield, which serves as a decorative member.

         20 . An in-vehicle heating device comprising:
 an air feeder positioned at a front reverse side of a seat cushion serving as a seating unit of a vehicle seat and including a suction opening through which external air is sucked into the air feeder, the suction opening being provided facing downward;   a warm air generator positioned downstream of the air feeder and including a heater therein, the warm air generator being configured to heat an air flow from the air feeder to generate warm air; and   a blow-out unit positioned forward of the warm air generator, the blow-out unit being configured to blow out the warm air from the warm air generator, such that the warm air is brown out forward of the seat cushion, wherein   the blow-out unit is configured to blow out the warm air forward from a position above the suction opening.   
     
     
         21 . The in-vehicle heating device according to  claim 20 , wherein
 the blow-out unit has a flat shape that is wide in a width direction of the seat cushion,   the blow-out unit has a thickness less than that of the warm air generator, and an interior of the blow-out unit serves as a warm air passage, through which the warm air from the warm air generator flows, and   a front end of the blow-out unit is disposed at a position that is above the suction opening and that is at a front of the seat cushion, and a blow-out opening configured to blow out the warm air is provided at the front end of the blow-out unit.   
     
     
         22 . The in-vehicle heating device according to  claim 21 , wherein
 the blow-out opening is provided facing diagonally downward at the front of the seat cushion.   
     
     
         23 . The in-vehicle heating device according to  claim 21 , wherein
 the blow-out opening is configured as a slit-shaped opening, which is wide in the width direction of the seat cushion.   
     
     
         24 . The in-vehicle heating device according to  claim 20 , wherein
 a blow-out opening configured to blow out the warm air is provided at a front of the warm air generator, and is positioned above the suction opening, and   the blow-out unit is plate-shaped and extends from an upper edge of the blow-out opening to reach a position at a front of the seat cushion, the blow-out unit being configured as a warm air guide plate guiding the warm air from the blow-out opening along a front surface of the warm air guide plate to the front of the seat cushion.   
     
     
         25 . The in-vehicle heating device according to  claim 24 , wherein
 a distal end of the warm air guide plate is curved diagonally downward at the front of the seat cushion.   
     
     
         26 . The in-vehicle heating device according to  claim 20 , wherein
 a blow-out opening configured to blow out the warm air is provided at a front of the warm air generator and is positioned above the suction opening, such that the warm air generator doubles as the blow-out unit, and   a suction guide member, which is configured to introduce external air from a position forward of the seat cushion into the suction opening, is provided below the air feeder.   
     
     
         27 . The in-vehicle heating device according to  claim 20 , wherein
 the heater is provided in the warm air generator such that the heater extends in a manner to cross an air-feeding direction from the air feeder, and   in the warm air generator, a straightening member configured to direct the air flow from the air feeder toward the heater is provided at a position rearward of the heater.
