Definitions
- the invention relates to a heating device for vehicles, with a burner, which has a fuel supply device and a combustion air blower, and a heating power control device, it being possible to switch between different power levels, in which the combustion air blower runs in each case mix at a predetermined speed.
- the heating power is regulated in accordance with one or different parameters, for example the temperature of the heating medium (air or water).
- a more comfortable version of such heating devices provides several, for example two, power levels. In normal operation, there is then a constant change between, for example, full load and partial load, depending on the state of the parameter parameters which are decisive for the regeneration process.
- ERSATZBL ⁇ I7 (RULE 26) When switching from one to the other power level, there is in particular a change in the speed of the combustion air blower, and accordingly also a change in the fuel supply via the fuel pump.
- the speed changeover of the combustion blower now brings not only considerable switching noise with devices controlled by means of relays, but also when using semiconductor switching elements and the like.
- the rapid change in speed of the combustion air blower is usually accompanied by clearly audible and possibly unpleasant noises, which are caused, for example, by vibrations in the housing or the like.
- the present invention is intended to remedy this.
- the object of the invention is to develop a heating device of the type mentioned at the outset in such a way that the transition between different power levels is practically silent.
- This object is achieved in that a smooth transition is provided in the case of a transition from one power level to another.
- “Sliding transition” here means in particular the departure from the sudden change in the speed of the combustion air fan. If the speed of the combustion air blower decreases, for example, from a high Wen at full load to a half of Wen at partial load, the "smooth transition" takes place within a time interval of, for example, one minute. A correspondingly long transition area is also provided when the speed increases.
- SPARE BLADE (RULE 26)
- the transition from one speed to the other of the combustion air blower is extended so long that the desired power level (speed of the combustion air blower) is not reached at all, but before that there is yet another switchover so that after a downshift, for example gradual decrease in the speed of the combustion air fan, a subsequent gradual increase in the speed of the fan takes place, and vice versa.
- Fig. 1 is a block diagram of a heater for vehicles
- Fig. 2 different speed curves in a combustion air fan of a heating device.
- FIG. 1 The construction of a heating device for vehicles shown in FIG. 1 is known per se.
- a burner 2 In order to generate a flame in a combustion chamber 4, a burner 2 contains a fuel feed line 6 with a fuel pump 8 for supplying fuel to an evaporator, atomizer or other comparable device (not shown here).
- a combustion air blower 10 serves to supply combustion air in accordance with the direction of the arrow shown.
- the fuel / air mixture is ignited by an ignition device 12 at the beginning of an operating cycle, so that a flame is produced in a flame tube 14 of the combustion chamber 4.
- the exhaust gases escape through an exhaust duct 16.
- the flame tube 14 is surrounded by a water jacket 18, in which the water serving as heat carrier is circulated by a pump 20.
- the temperature of the water is detected by a temperature sensor 24 in the area of a water outlet 22.
- the temperature sensor sends corresponding signals to a heating power control circuit 26.
- the arrangement of the flame tube 14 and the water jacket 18 forms a heat exchanger 18 which ensures the heat transfer from the combustion gases to the water in the water jacket 18.
- the water flowing in the direction of the arrow is cooled by a water / air heat exchanger 28 shown on the right in FIG. 1. That one- when warm air coming from the heat exchanger 28 reaches a passenger compartment shown here in dash-dotted lines.
- FIG. 2 shows at "A" the time course of the fan speed of the combustion air fan 10 shown at the bottom left in FIG. 1.
- VL full load
- TL part load
- Fig. 2 "B” the transition of the fan speed from full load (VL) to partial load (TL) takes place gradually, e.g. within a period of more than about a minute. Conversely, the transition between partial load (TL) and full load (VL) also takes place gradually, e.g. within a period of about a minute.
- the heating power control circuit shown in FIG. 1 contains corresponding circuit elements with which the gradual transitions shown in FIGS. 2B and 2C are implemented.
- a microprocessor is provided in the heating power circuit 26, which adjusts the desired course of the speed of the combustion air blower.
