Definitions

  • the present invention relates to an oven with a lockable oven muffle, with a cooling air blower outside the furnace muffle, the pressure side of which ins Free leading exhaust air duct arranged above the muffle is connected in the one on the edge, fluidly connected to the furnace muffle and one Vapor blower, vapors channel with a vapor injection opening that opens is extended by a vapor duct connector that extends across the exhaust duct extends and the vapor discharge opening arranged in the flow path of the exhaust duct and is turned away from the main exhaust air flow direction, which vapor duct connector on the bottom through a base plate of the exhaust air duct and on the top through a vapor guide plate is formed.
  • Such an oven is known from the publication DE 93 09 989 U1, the Mouth opening of the vapor duct in the edge area of the exhaust air duct in the flow path the exhaust air is arranged so that a laminar flow of the exhaust air and a laminar introduction of the vapor flow into the exhaust air is effected.
  • the damp vapor is therefore enveloped by the exhaust air and in the edge area of the front opening of the exhaust duct to the outside.
  • the object of the present invention is in an oven according to the preamble of claim 1 to improve the distribution of the blown vapors.
  • this is achieved in a generic oven in that the vapor duct connector extends at least over 1/3 of its width transversely to the main exhaust air flow direction extends. Due to the length extension of the vapor duct connector the vapors can be better targeted across the width of the exhaust air duct as well be distributed. This is particularly due to the use of the additional vapor blower evenly and with sufficient pressure possible. Through the vapor blower is excluded that the vapors due to the conveyed by the cooling air fan Main cooling air stream is pressed back into the furnace muffle.
  • the vapor duct connector is used to increase the free Flow cross section of the exhaust air duct in the area of the connector lowered in Exhaust duct arranged.
  • the vapor duct connector acts on the exhaust air flow hardly as a disadvantageous flow barrier.
  • the vapor blower is approximately at the level of Bottom plate of the exhaust duct or arranged above.
  • the vapor blower or the blower motor are still sufficiently spaced arranged above the hot muffle.
  • the fume duct connector has at least two vapor discharge openings arranged at a distance from one another on.
  • An oven 1 has an oven housing 3 known per se (in FIGS. 1, 2 for reasons of simplification (not shown), which is a cuboid oven muffle open at the front 5 surrounds. For heating the oven muffle 5 or the cooking space, these are not closer shown and controlled by a control unit of the oven 1 in heating elements assigned in a known manner.
  • the furnace muffle 5 has a suitable circumference thermal muffle insulation 7 provided.
  • the Cover hood 13 has a base plate serving as the top wall of the exhaust air duct 9 and on both sides of the base plate protruding at right angles as the side walls of the Exhaust duct side walls.
  • Via openings in the furnace housing, not shown in detail 3 sucks one connected to the rear opening of the exhaust air duct 9
  • Cooling air blower 15 Cooling air in a manner known per se into the furnace housing 3.
  • the cooling air blower 15 presses after cooling suitable components, e.g. electronics, or place the oven 1, the heated cooling air in the exhaust duct 9 ends in suitable cooling air front openings 17 of the oven 1 at the front.
  • the cooking space is used to discharge vapors that arise during the cooking process tubular or tubular vapor duct 19 with a muffle insulation on the top side 7 or the bottom plate 11 of the exhaust duct 9 arranged spiral housing 21 connected.
  • a fan wheel of a vapor blower 22 is located inside the volute casing 21 supported.
  • the fan motor 41 driving the fan wheel sits on the spiral housing 21.
  • the fume blower 22 draws when required, controlled by the control unit of the oven 1, the hot vapors from the oven muffle 5 through the vapor channel 19 into the spiral housing 21 and presses the vapors out of one provided in the edge region of the exhaust air duct 9 Vapor injection opening 23 of the volute casing 21.
  • the vapor fan can also be arranged in the vapor duct and the spiral housing is dispensed with, if the vapor channel with a vapor injection opening extends to the edge area of the exhaust duct 9 extends.
  • a vapor duct connector 25 is provided in the area of the vapor injection opening 23, an extension of the vapor channel 19 or the volute casing 21 .
  • the vapor duct connection piece 25 through an elongated recess 27 (FIG. 1) stamped in the base plate 11 and a vapor guide plate 29 mounted on the base plate 11 is formed.
  • the vapor guide means 29 can also be realized with a suitable plastic material.
  • first vapor discharge opening 31 which is spaced closer from the vapor blower 22, is different almost over half the length of the air baffle 29 and essentially exactly between the front edges of the air baffle 29 and the recess 27 of the Bottom plate 11 extends in this area, which is further apart from the vapor blower 22 second vapor discharge opening 31 is shorter and oblique to the first Vapor outlet opening arranged.
  • second vapor exhaust opening 31 in this area must also be provided with a sufficient opening cross section the vapor guide plate 29 cut back in comparison to the edge profile of the depression 27.
  • the vapor guide plate 29 has a hood-shaped connecting section 33, whose inlet cross-section corresponds to that of the vapor injection opening 23 of the volute 21.
  • connection section 33 At the connection section 33 is a flat drawn down Flow section 35 of the vapor guide plate 29. This projects in the flow section 35 Vapor guide plate 29 only slightly above the top of the base plate 11 in the Exhaust duct 9. This ensures that the cooling air blower 15 in the exhaust duct 9 flow promoted only slightly by the transverse to the main exhaust air flow direction arranged vapor duct connector is impaired. Because of the deepening 27 has the vapor channel connector 25 in the flow section 35 approximately same free flow cross-section as in the connection section 33 or the vapor injection opening 23 of the volute casing 21.
