Definitions

  • the invention relates to a warm air heater according to the Preamble of claim 1.
  • the warm air can either be caused by a chimney-like one Generate heating system and / or by an electric heater.
  • the Warm air then circulates over heat storage stones.
  • the input temperature should be relatively high via storage stones adequate heat radiation along the entire circulation path to get the warm air.
  • the air circulation must pass through a Fan to be supported, which is to be arranged in a heat chamber. As the temperature of the hot air to be circulated increases Difficulty with the bearings of the fan because of the temperature which endure the bearings in continuous operation without damage, is limited.
  • the object of the invention is to be achieved in a warm air heating system the bearings of a fan arranged in a heat chamber to protect against overheating.
  • shut-off devices either on recirculated air, fresh air and room air supply or can be switched to storage mode.
  • the generation of warm air can be done either by a fireplace, for example of the type shown in Fig. 3 or by Electric heating. It is also possible to combine the two types of heating to combine so that, for example, in the event of a long absence the electric heater is switched on manually or automatically as required can be.
  • a pre-heating chamber is located on a base box or base 7 7 or overpressure chamber in which a ventilation box 21 is built into it.
  • the warm air to be circulated is here fireplace not shown, for example a natural stone oven, warmed, which housed in a remote housing is.
  • a fan designed as a radial fan 24 - also a radial fan called - serves for the closed circulation of warm air and is located inside a heat chamber 20.
  • the variable speed electric drive motor 22 - at most together with control electronics - Is arranged outside the heat chamber 20.
  • the motor 22 is outside of a casing 19 surrounded with openings for access to room air.
  • the two lateral bearings 50, 51 of the fan 24 are preferably ball bearings, the resiliently supported on a housing surrounding the fan impeller or are hung.
  • the fan housing is one after Provide outlet opening facing above.
  • the cooling of the ball bearings 50.51 takes place by supplying cooling air such as this is indicated by arrows in Fig. 1.
  • the cooling air for the bearing 50 is fed through a channel 54 which is between the radial fan and the housing 19 is located. In Fig. 2, this channel is the For the sake of clarity, partially open.
  • a hose or pipeline 60 is provided, which starts from the housing 19 which surrounds the motor 22.
  • the cooling air could instead of from space 23 also from anywhere in the area be sucked in.
  • the cooling air is then turned of the fan impeller 24 by its axially extending, inclined blades spaced apart from one another in the circumferential direction 29 is transported radially outwards, where it finds itself with the warm air in the heating chamber 20 mixes.
  • the cooling air for the ball bearings is thus from Fan impeller 24 is sucked in without an additional fan or Like. is necessary.
  • the cooling air causes the temperature of the bearings be kept at a temperature permissible for continuous operation can.
  • the warm air is circulated by the radial fan 24 through a Nozzle 25 discharged upwards and then to the storage stones passed, as explained below with reference to FIGS. 2 and 3 becomes.
  • the embodiment shown in Fig. 2 relates to an electric heater, in which the heat by a resistance heater, not shown is produced.
  • the structure is similar to that in Fig. 1, wherein same reference numbers mean same parts.
  • the housing 19 stands for Cooling of the bearings 50, 51 in connection with the room air.
  • the cooling channel 54 is shown partially open to make the drive shaft 56 visible.
  • the drive motor 22 together with any associated electronics is from the heat chamber 20 through a heat insulating partition 69 severed.
  • the 3 contains a housing 1 with a Base 2.
  • the combustion chamber 4 with grate 5 is through a movable viewing window 3 lockable. From the combustion chamber 4 leads in the usual way a flue gas pipe 6 in a chimney.
  • a conventional heat exchanger 8 which is heated by the flue gases is and gives off heat to the circulating air, which circulates through the tube 10 Emits air.
  • the hot air passes from this pipe section 10 on upper end of the housing through lines 12 via an inlet connection 9
  • Storage stones 12 are hollow and preferably contain baffles 14 to create turbulence.
  • Of the Outlet 16 of the storage stones 12 stands for the return air via a line with a pipe stub 18 in the base 2 in flow connection. Thereby the warm air can move in a closed circulating air system.
  • Fig. 4 shows a horizontal section through the base 2 of a heating device 3 with the heat chamber 20 with a mixing room 17 is combined.
  • the heat chamber 20 is the through the radial fan 24 driven by the motor 22.
  • the two pairs of end flaps 30, 31 and 36, 37 are via holders 39, 40 with a common actuating rod 42 connected.
  • actuating rod 42 One engages in this actuating rod 42 Pivot 44 a pivotable lever 46, which - according to FIG. 5 - over a further linkage 48 connected to an outwardly projecting hand lever 49 is.
  • the lever movement is thus a multiple translation on the operating rod 42 transferred.
  • the extreme locations are either the openings 26, 28 closed by the flaps 30, 31 and at the same time the Openings 32, 34 opened by the flaps 36, 37 and vice versa.
  • the Bearings 50, 51 of the fan 24 in the heat chamber 20 fresh air the fresh air inlet duct 54 is supplied. This allows the temperature to succeed cool the bearings to such an extent that the bearings - preferably ball bearings - take no damage, even if the temperature in the heating chamber 20 is relatively high.
  • the flaps 36, 37 are opened, fish air and Indoor air via the nozzles 53 and 66 in the combined heat and Mixing chamber 20, 17 and then flows into the driven by the fan 24 Outlet pipe 64 (Fig. 3). From there, the warm air flows openly into the one to be heated Rooms.
  • the fresh air can be connected via connections 53/66 or 18/62 will.
  • connections 53/66 the flaps 36, 37 are closed and at the same time the Connections 18/62 from and to the storage stones open, so that one internal circuit (circulating air) via the storage stones 12 forms.
