Definitions

  • the invention relates to an oven, comprising a baking chamber, a circulating air fan driven by an electric motor, a heat exchanger and devices for supplying Water and fresh and cooling air.
  • Such ovens are for example in EP 0 386 862 B1, EP 0 926 449 B1 or US 6,023,050. These ovens have a planar motor wall, in which a motor for Driving a forced air fan is provided, which on the has a carrier plate facing the baking chamber.
  • a separate blading is used for the air supply in EP 0 386 862 B1 needed, while in EP 0 926 449 B1 the air supply at a point where the highest is not Intake vacuum is present in the air circulation fan.
  • EP 0 926 449 B1 one is used to moisten at least partially Steam-filled cooking space of a steam cooker or a hot air-steam mixture by means of a fan wheel Radial fan circulated in the cooking space.
  • Radial fan circulated in the cooking space.
  • the gas mixture to be circulated essentially sucked axially and directed radially outwards.
  • Excess steam or excess hot air / steam mixture is drained from the cooking space through an exhaust air opening. Dry fresh air from outside is used for dehumidification fed on the rear above the axis of rotation of the fan wheel, by provided in the rear end of the fan wheel Opened openings and by means of deflection devices the fan wheel is deflected outwards.
  • the object of the invention is to design an oven in such a way that the heat exchanger through the circulated, fat droplets entrained air flow, is contaminated as little as possible and also regulates the fresh air drawn into the baking chamber is fed.
  • this object is characterized by the features in characterizing part of claim 1 solved.
  • advantageous Further training is the subject of subclaims.
  • FIG 1 is a preferred in a schematic longitudinal section Embodiment of a designated 1 in its entirety Oven shown with outer jacket 2.
  • Oven 1 has a baking space 3, which is connected to an oven door 6 is accessible.
  • In the baking room 3 are schematic baking containers 5 arranged one above the other for receiving baking foods indicated.
  • a drive for a circulating air fan 11 an electric motor 10 is provided.
  • a hub 11a of the circulating air fan 11 attached, which in turn also is referred to as a washer carrier plate 11b attached.
  • Buckets 11c are provided which are approximately parallel in number go to the axis 12 extending blades 11d.
  • the number of radially extending blades 11c can be the same, smaller and / or larger than the number of axially extending Be blades 11d.
  • an electric motor adjustable disc 11e provided that about the same diameter as the carrier disc 11b and about that same number, for example, arranged in the same position, preferably equally sized openings such has those in the support plate 11b.
  • an approx vertically aligned air baffle 17 is arranged between the actual Baking chamber 3 and the fan 11. Further a heat exchanger is arranged in the area of the circulating air fan wheel 11.
  • FIG 2 is also in a schematic longitudinal section an oven designated in its entirety with 1 ', which is a modification of the embodiment of the in Fig.1 illustrated oven 1.
  • the main difference is that the drive motor 10 is not in one Recess is housed, which is why the oven 1 ' has a greater depth.
  • this also results in a adequate suction negative pressure is generated in the recess 9.
  • About the more or less wide open or, if necessary completely closed openings in the carrier disc 11b and the disk 11d associated therewith can over it in addition, for example, by electric motor adjustment Disc 11b in relation to the carrier disc 11b the suction vacuum and at the same time the amount supplied Fresh air can be regulated or blocked accordingly.
  • locking mechanism for Control of the amount of fresh air may be provided. After mixing the fresh air with that in the baking chamber 3 climate becomes excess air through the outlet 7 to the outside blown.
  • the baking climate can also be from outside the baking chamber 3 provided (not shown) steam generator generated and steam directed into the baking chamber and / or also through the in the baking chamber 3 by injecting and evaporating the Water supplied via the pipeline 15 on the heat exchanger 16 developed steam can be humidified.
  • the injection water intended for evaporation is over the pipe 15 and the opening 15a to the axially aligned Blades 11d passed through which the supplied Water is atomized and transported to the heat exchanger 16, whereupon the water evaporates.
  • the water supply line 15 By laying the water supply line 15 in the interior of the recess 9, in which the temperature is much lower than in the baking room 3, is a heating and thus a quick calcification and possibly clogging the water supply line 15 as well how excluded. That is, due to the advantageous Laying the water supply line 15 outside the baking chamber 3 there is free water flow.
  • Figure 3 is also in a schematic longitudinal section an embodiment of an oven 1 "shown, in which the line 15 for water supply and the lines 14 for the supply of cooling air.
  • this embodiment is otherwise, as in the embodiments in Fig.1 and 2, in the space between the outer jacket of the Motor 10 and the side of the recess facing the motor 9 a thermal not shown in the drawings Insulation attached.
