Definitions

  • the invention relates to a gas-heated clothes dryer with a program selection and Control device, a device for regulating the heating operation and a device for the gas supply to a gas burner that can be operated either with natural gas or LPG as well as with a fan that promotes the combustion air.
  • EP 0761 863 A1 describes a gas-heated clothes dryer known with a primary air controlled premix burner, in which no secondary air supply to the burner surface. The combustion air supply to the burner surface becomes alone regulated via the primary air supply. The process air for the drying process is the one Process air duct surrounding the combustion chamber and does not come into direct contact with the burner surface. This training causes low-pollutant combustion.
  • gas-fired devices with devices for regulating heating operation known in which an adjustment of the gas supply to different types of gas manually replaceable nozzles.
  • the manual replacement of the nozzles is e.g. B. from the Heating construction known.
  • gas-heated clothes dryers are known, in which also an adaptation to different gas types via manually exchangeable nozzles he follows.
  • the invention thus presents the problem of adapting the device to different ones To simplify and automate gas types or nominal gas pressures, so that a Adaptation with simple means or automatically through devices in the device can be done.
  • the advantages that can be achieved with the invention are, in particular, that adaptation to the existing gas type with simple means without changes to the gas supply or Gas system can also be done automatically if necessary. All that is required is the air ratio be corrected, which is possible by simply changing the primary air supply.
  • the primary air volume is varied by changing the vacuum in the combustion chamber. This happens advantageously through the use of an air throttle in the exhaust air duct or Change in fan speed.
  • the air throttle can be easily removed from the Operator are used.
  • a change in the fan speed is also over corresponding selector switch on the program selection and control device possible.
  • a combination of air throttle and speed change is also conceivable.
  • FIG. 1 shows the structure of a gas-heated clothes dryer and the air flow from Process air and combustion air are shown schematically.
  • the tumble dryer comes with a Program selection and control device (1), a device for controlling the heating operation (2) and a device for the gas supply (3) to either with natural gas or LPG operable gas burner (4).
  • the tumble dryer has a rotatably mounted Drum (5) for receiving the laundry to be dried, which is closed by a door (6) is in the process air duct (7) to the drum inlet (8) the burner (4) arranged gas-heated heating device.
  • the process air as well as the combustion air is via the process air blower (9) in the process air duct (10) from the drum outlet (11) sucked in and passed through the drum (5) and then via the exhaust air duct (12) to the Environment.
  • the burner (4) is a primary air controlled premix burner.
  • the Mixing chamber (13) has a primary air opening (14).
  • the gas nozzle (15) opens into the Mixing chamber (13) and is arranged so that the primary air supply through the Injector effect of the gas nozzle (15), but by the generated by the blower (9) Negative pressure is determined. This is achieved in that the fan (9) in Flow direction of the process air seen behind the drum (5) and the burner (4) is arranged so that drum (5) and burner (4) are in the vacuum region.
  • a first embodiment provides for the fan speed to vary.
  • a setting option is available via a keyboard, not shown on the program selection and control device (1).
  • a second version is in the Exhaust duct (12) an air throttle (16) arranged.
  • the throttle (16) can be fixed Have opening cross-section or be provided with adjusting means, not shown, the one Allow changing the opening cross-section. It is also a combination of Air throttle (16) and change in fan speed possible.
  • Figure 2 shows a section of the rear wall (17) of the dryer and the ring-shaped reducing insert (18) in the exhaust air opening (19) of the exhaust air duct (12) in the rear wall (17).
  • the reducing insert (18) is installed before the Connection piece (20) used for the exhaust air line.
  • the reducing insert shown here (18) has a fixed opening cross-section.
