专利汇可以提供Vehicle heater专利检索，专利查询，专利分析的服务。并且A self-contained automatic heater unit for a vehicle such as a truck trailer or the like in which a temperature sensor automatically ignites a pre-heater by means including a rechargeable power source to supply a mixture of hot air and fuel to a burner plate of large area the burners of which are ignited when the pre-heated mixture reaches a certain temperature and the products of combustion of which are first brought into contact with the hot junctions of a thermopile and then are passed through a heat exchanger to which air from the space to be heated is supplied by a fan which first moves this cool air past the cold junctions of the thermopile and then through the heat exchanger to the space to be heated and in which the voltage produced by the thermopile recharges the battery which provides a power source for the system.，下面是Vehicle heater专利的具体信息内容。
1. A self-contained heater unit for heating the air within a space including in combination, a housing having an inlet and an outlet communicating with said space, an indirect heat exchanger in said housing, a thermoelectric generator comprising a plurality of thermocouples each having a hot junction and a cold junction and means mounting said thermocouples in Said housing with said junction distributed over extended areas, a main burner plate comprising a plurality of burners in said housing distributed over an area adjacent to the hot junction area, a preheater, means including said preheater for supplying a mixture of preheated air and fuel to said main burner plate, a rechargeable source of power, means for sensing the temperature of the air within said space, means including said means for sensing the temperature of air within said space for connecting said source to said preheater to activate said preheater, means responsive to the temperature of said mixture for igniting fuel supplied to said burner plate to cause said burners to produce hot products of combustion, means for passing said hot products of combustion over said hot junctions and to said indirect heat exchanger, means for passing air from said space successively over said cold junctions and to said indirect heat exchanger and back to said space, said thermopile producing a voltage in response to the temperatures of said hot products and said air, and means for applying said voltage to said source of power to recharge the same, said preheater comprising a blower, means adapted to be energized to supply fuel to said preheater and means for igniting said fuel supplied to the preheater, said means responsive to the means for sensing temperature of said air in said space comprising means for connecting said blower and said fuel supply means and said igniting means to said source.
2. A self-contained heater unit for heating the air within a space including in combination, a housing having an inlet and an outlet communicating with said space, an indirect heat exchanger in said housing, a thermoelectric generator comprising a plurality of thermocouples each having a hot junction and a cold junction and means mounting said thermocouples in said housing with said junctions distributed over extended areas, a main burner plate comprising a plurality of burners in said housing distributed over an area adjacent to the hot junction area, a preheater, means including said preheater for supplying a mixture of preheated air and fuel to said main burner plate, a rechargeable source of power, means for sensing the temperature of the air within said space, means including said means for sensing the temperature of air within said space for connecting said source to said preheater to activate said preheater, means responsive to the temperature of said mixture for igniting fuel supplied to said burner plate to cause said burners to produce hot products of combustion, means for passing said hot products of combustion over said hot junctions and to said indirect heat exchanger, means for passing air from said space successively over said cold junctions and to said indirect heat exchanger and back to said space, said thermopile producing a voltage in response to the temperatures of said hot products and said air, and means for applying said voltage to said source of power to recharge the same, said preheater comprising a first blower, means adapted to be energized to supply fuel to said preheater and means for igniting said fuel supplied to said preheater, said mixture supplying means comprising a heat exchanger and fuel vaporizer adapted to receive air from said first blower and the hot products of combustion from said preheater and means for supplying fuel to the vaporizer, said means for passing air to be heated including a second blower, said means responsive to the means for sensing the temperature of air in said space including means for concomitantly connecting said first blower and said preheater fuel supply means and said preheater fuel igniting means to said power source, said unit including means responsive to ignition of said preheater fuel for disconnecting said preheater fuel igniter from said source, said means for igniting said mixture fuel including means for actuating said vaporizer fuel supply means, said unit including means responsive to ignition of said mixture fuEl for concomitantly deenergizing said mixture fuel igniting means and energizing said second blower.
