Definitions

  • the invention relates to an oven with a baking muffle, wherein a cross-flow fan with a subsequent cooling air duct generates a cooling air flow, the discharge takes place into the open, and wherein in the cooling air duct a Wrasenabzugskanal opens, through which the vapor is sucked out of the baking muffle.
  • an oven in which the point of confluence of the vapor extraction channel is arranged in the vicinity of the air outlet opening of a formed as a cooling air collecting duct exhaust duct.
  • an air guide plate is arranged in the known embodiment in the cooling air collecting channel, in order to mix the cooling air flow, which flows at a relatively high speed, the vapors according to the injector principle.
  • DE 37 41 975 is a device for controlling a steam-operated cooking appliance, which is equipped with one of a fan with the cooling air flow generated in the pressure channel.
  • the blower is provided with a leading from the pressure channel to the suction side of the blower return line, which communicates with the cooking chamber via a closable steam outlet opening.
  • the vapor outlet can be controlled.
  • the invention thus raises the problem of further developing an oven with a baking muffle in such a way that the connection of a vapor extraction channel to its constructional or structural design is substantially simplified.
  • connection of a vapor extraction channel is considerably simplified by its structural or structural design.
  • the cross-flow fan draws in strong air from the outside and into the cooling air duct.
  • an opening in the housing of the cross-flow fan is provided, so that a simple direct coupling of the underlying treatment space by means of the Wrasenabzugskanals.
  • the exhaust duct and the exhaust pipe / mixing box can be reduced to a minimum.
  • the entire Wrasenabsaugung consists in minimal form only from the modified cross-flow fan and two underlying openings in the mounting plate and in the baking muffle to realize the flow-conducting coupling of the baking muffle by means of the vapor evacuation channel thus formed.
  • the exhaust duct can be omitted if the cross-flow fan is arranged with its blow-out in the immediate vicinity of the exhaust opening of the oven housing.
  • the mouth region of the vapor extraction channel is in this case arranged directly in the vicinity of the blow-out region of the cross-flow fan, at which the required suction capacity for the vapor from the vapor extraction channel is established at a minimum rotational speed of the fan wheel.
  • the mouth region is arranged in the flow direction of the cooling air flow behind the fan.
  • the mouth region is arranged relative to the cross flow fan such that the pumping speed is greatest at maximum speed of the cross flow fan. It is advantageous to the discharge of the Cross-flow fan an exhaust duct for discharging the mixed air flow from cooling air and vapor attached.
  • the cross-flow fan with the suction opening for the mouth region of the vapor extraction channel is in this case arranged on a mounting part, wherein the mounting part for this purpose has an opening.
  • the FIG. 1 shows a baking oven 1 with a baking muffle 2, wherein above the baking muffle 2 a cross-flow fan 3 with a subsequent cooling air duct 4 generates a cooling air flow, the discharge takes place in the open.
  • the mouth region 5 of a vapor withdrawal channel 6 is arranged directly in the vicinity of the blow-out region 7 of the cross-flow fan 3.
  • a pumping speed for the vapor from the vapor outlet channel 6 a arises at an empirically determined minimum speed of the fan 8, a pumping speed for the vapor from the vapor outlet channel 6 a.
  • the mouth region 5 is arranged in the flow direction of the cooling air flow behind the impeller 8, which is only hinted at here.
  • the mouth region 5 is arranged relative to the cross-flow fan 3 such that the pumping speed is greatest at the maximum rotational speed of the cross-flow fan 3.
  • an exhaust air duct 9 for discharging the mixed air flow from cooling air and vapor can be attached to the blow-out region 7 of the cross-flow fan 3.
  • the cross-flow fan 3 is arranged with a suction opening 10 for the mouth region 5 of the vapor withdrawal channel 6 on a mounting part 11, wherein the mounting part 11 for this purpose has a corresponding opening 10 to the suction port.
  • the mounting part 11 in its functional effect is better seen in the FIG. 3 , Of the Cross-flow fan 3 is fixed by means of the mounting part 11 in a simple manner to the rest of the oven 1.
  • the jacket region 12 of the cross-flow fan 3 is provided with letters from "A" to "L". These letters indicate the pressure measurement points of tests performed and are also plotted on the x-axis in the diagrams below, from “A” to "L”. On the Y-axis, the pressure conditions, ie overpressure or negative pressure, indicated that set at maximum speed of the cross-flow fan 3.
  • the range from "A" to about "D" of the blow-out 7 a Represents suction zone.
  • FIG. 4 shows a further graph, wherein in the graph on the X-axis, the measuring points "A" to "L" of the lateral surface 12 of the cross-flow fan 3 are plotted, wherein the solid line represents the suction pressure behavior of the cross-flow fan 3, if he with his Maximum speed is operated. Recognizable in the graph is a pumping speed of the cross-flow fan 3 in the region between the first and fourth measuring point. If the fan speed is reduced, as shown by the dashed line, the result is also in the range of the first to fourth measuring point "A" to "D” a pressure range.
