Definitions

  • the invention relates to a vehicle heater with a burner, a combustion air blower with a combustion air blower motor, and a control unit, the control unit being arranged in the same housing as the combustion air blower motor.
  • the invention further relates to a method for assembling a vehicle heater.
  • Vehicle heaters can be used, for example, as additional heaters or as auxiliary heaters in motor vehicles. It is particularly preferred if the vehicle heaters can work independently of the internal combustion engine of the motor vehicle.
  • the heat energy in vehicle heaters is generally generated by burning the motor vehicle fuel, for example diesel or gasoline, in a burner.
  • a combustion air blower is often provided which is operated by means of a combustion air blower motor.
  • a control device assigned to the vehicle heater which controls or regulates the functions of the vehicle heater.
  • the control unit receives different information, for example information from sensors or also information from operating elements, so that the operation of the vehicle heater can be influenced as a function of this information.
  • This influencing the operation of the vehicle heater affects, for example, the fuel supply or the operation of the combustion air fan. The latter will achieved by the control unit controlling the combustion air blower motor.
  • control device is arranged in the area of the heat exchanger, that is to say in the area in which thermal energy is absorbed by a heat-carrying medium, for example water.
  • a heat-carrying medium for example water.
  • This arrangement of the control device has the advantage that, for example, temperature sensors which are intended to determine the temperature of the heat transfer medium can be arranged directly on a circuit board of the control device. This makes cumbersome cable routing unnecessary and the temperature determination is not prone to errors.
  • a disadvantage of such a solution is that very high temperatures occur on the control unit, if this is arranged in the area of heat transfer, which can sometimes assume values at which reliable operation of the control unit can no longer be guaranteed, or even damage to the control unit can.
  • US Pat. No. 5,855,319 describes a vehicle heating device in which the control device is not arranged on the heat exchanger. Rather, the control unit is provided in a housing end part, which forms a common housing for the control unit and combustion air blower motor in the assembled state of the vehicle heater. In this way, the control unit is protected against excessive exposure to heat. However, additional cabling is required.
  • a temperature sensor which can be arranged, for example, in the area of the heat exchanger, would have to be connected to the remote control device via a cable.
  • the invention has for its object to provide a vehicle heater in which the disadvantages of the prior art are eliminated, in particular re a control unit arranged away from the heat exchanger is to be provided, which does not require excessive cabling.
  • the invention is distinguished from generic vehicle heaters by the fact that the combustion air blower motor is brought into direct engagement with mating contacts on a circuit board of the control unit with contacts guided to the outside.
  • the additional wiring effort for temperature sensors that may be provided in the area of the heat exchanger is accepted.
  • the additional wiring effort is compensated for by reducing the line connection between the combustion air blower motor and the control unit. By contacting the combustion air blower motor directly with the circuit board of the control unit, any cabling in this area can be omitted, so that the present invention provides an inexpensive and easy-to-assemble structure.
  • the vehicle heater according to the invention is developed in a particularly advantageous manner in that the vehicle heater is a water heater.
  • an arrangement of the control device in the blower housing is particularly advantageous in such a water heater, in which case the advantage according to the invention of Contacting the motor directly with the circuit board of the control unit can come into play.
  • the invention further consists in a method for assembling a vehicle heating device, in which contacts of a combustion air blower motor which are led to the outside are directly contacted directly with a circuit board of a control device.
  • a combustion air blower motor which are led to the outside are directly contacted directly with a circuit board of a control device.
  • the invention is based on the knowledge that the control device can be protected against excessive heat by being arranged at a distance from the heat exchanger.
  • the increase in cabling between temperature sensors in the heat exchanger area and the control unit is compensated for by the fact that cabling between the combustion air blower motor and the control unit can be omitted.
  • Fig. 1 is a schematic representation of part of a vehicle heater according to the invention.
  • Fig. 2 is an enlarged view of a contact area between the combustion air blower motor and the circuit board of the control unit.
  • FIG. 1 shows a schematic illustration of part of a combustion air blower housing 10.
  • a combustion air blower is located in this combustion air blower housing 10.
  • motor 12 which drives a shaft 14.
  • the blower motor 12 is connected directly to mating contacts 22, 24 on a circuit board 20 of the control unit via two contacts 16, 18 which are led to the outside.
  • the connection can be established by inserting spring-loaded contacts 16, 18 into corresponding bores in corresponding conductor tracks that form the counter-contacts 22, 24.
  • the resilient preload can be achieved by forming corresponding resilient tongues 16A (see FIG. 2, corresponding to the detail X in FIG. 1) on the contacts 16 themselves or by a slight undersize or oversize in the spacing of the contacts 16, 18 with respect to the counter-contacts 22, 24 are generated.
  • the combustion air blower motor 12 is additionally mechanically connected, for example by locking or screwing, to at least one wall of the combustion air blower housing 10.
  • the contour of the walls 26 of the same possibly with corresponding projections 28 or pins, can also fix the combustion air blower motor 12 directly in its position without additional fixings being necessary.
  • the shaft 14 is fixed in the axial direction by a cover 30 of the combustion air blower housing 10.
