Definitions

  • the invention relates to a device for venting a Oven with muffle, with fan means and at least an engine.
  • Cookers and ovens can be equipped with filters for the vapors his.
  • the filters are usually made of one Wire mesh or have catalysts, whereby there is always a not inconsiderable resistance. So that enough vapors can be extracted from the muffle, the fan must pass through small suction cross sections of the housing be throttled, which in turn increases Noise emission leads.
  • a fan is specially designed for the Housing cooling is used, which is usually used as a cross-flow fan is designed.
  • a second fan is as Radial fan designed for the fume extraction. Since both fans each have their own motor, the disadvantage of this system is a high space requirement and an increased construction effort.
  • the invention is therefore based on the object of a device to ventilate an oven where optimal cooling with simple and inexpensive construction as well as good ventilation of the baking muffle with a motor can be achieved.
  • the object is achieved by at least one Air duct for the extraction of cooling air and vapors, with at least a first flow connection for a vapor air flow from the baking muffle and at least one second Flow connection for the cooling air flow for the outside environment the baking muffle loosened, the motor both a first fan wheel for the cooling air flow, as well as a second Fan wheel for the vapor air flow drives.
  • the fan wheel for the cooling air flow is advantageous an axial fan wheel and the fan wheel for the vapor air flow a radial fan wheel.
  • the motor can be between the fan wheel for the cooling air flow and the fan wheel for the vapor air flow, whereby it lies in the cooling air flow, whereby an additional Cooling the motor is effected.
  • the respective fan wheels that they are in each case in the flow connection, in particular in the opening of the air duct to the outside of the baking muffle or arranged in the opening of the air duct to the baking muffle are.
  • the Air duct can also be formed in two parts and for the Vapors and the cooling air each have a separate duct, which then lead to a mixing area in which both Streams are mixed together so that the vapors do not remains in its pure form in the area.
  • a plate that also serves to hold the motor, so form that they together with prefabricated pages and Connecting walls form the channel.
  • Fig. 1 is a schematic representation of an oven 2 shown with a device for ventilation 1.
  • the Oven is provided with a baking muffle 3, at the Top of the device 1 is arranged.
  • the device for ventilation points for the joint extraction of cooling air and vapors an air duct 5 which is connected to its in the Drawing right end to front 18 of oven 2 flows out and on its left in the drawing to Baking muffle 3 directed a flow connection 6 for the Vapor air flow 7 and opposite a flow connection 8 for the cooling air flow 9 for the outside environment 10 the baking muffle 3.
  • baffles or channel arrangements for the cooling air flow on the outside of the baking muffle be provided.
  • the motor shaft In the illustrated embodiment is in the space between the two Fan wheels 11 arranged a motor 4, the motor shaft a common shaft 13 for the first fan wheel 11 and forms the second fan wheel 12.
  • the first fan wheel for the cooling air flow 9 is an axial fan wheel trained, whereas the second fan wheel for the vapor air flow 7 is a radial fan wheel.
  • the radial fan wheel 12 can be a simple wheel without a cover disk a) with backward curved, b) with radially ending or c) with forward curved blades, as a wheel with Cover plate (also all three variants a), b) and c)) or be designed as a drum rotor.
  • the engine is between the radial fan and the axial fan.
  • the motor outside the air duct e.g. above the flow connection 8 be provided for the cooling air flow, so that the radial fan and the axial fan essentially side by side are arranged.
  • the Vapor duct 15 has a plate 17 which forms the air duct separates from the vapor channel and as the basis for the attachment of the engine. Under the plate 17 is the volute arranged for the radial wheel. Channel 5 is and connecting walls 5 'to 5' '' and the plate 17 formed, this plate on the one hand and the walls on the other can be individually manufactured components.
  • FIG. 2 shows a further embodiment in dashed lines Representation shown.
  • the respective flows of cooling air and of the fumes are in separate channels 14 and 15 up to one Mixing area 16 out. Both streams are there again merged.
  • the mixing area 16 can also be outside the oven immediately at the outlet of the two channels lie.
  • the motor can also be arranged outside the duct, and the drive of the two fan wheels 11 and 12 common shaft 13 take place via a belt drive.
  • the fan wheels 11 and 12 run on separate shafts that each with a different speed from the common Motor driven by separate belt drives.
