Definitions

  • the present invention relates to an oven with an oven muffle, in the Wall a vapor opening is provided, on which a suction housing with two from each other separate suction chambers is set, in which a vapor fan and a Cooling air fan wheel of a common fan motor are arranged, the vapor suction chamber with the oven muffle for vacuuming and blowing out the vapors is connected and the cooling air suction chamber with the housing space of the oven for sucking in and blowing out the housing space outside the oven muffle flowing cooling air is connected, and wherein both suction chambers discharge side at least into a blow-out duct and the fan motor is arranged in the cooling air flow.
  • Such an oven is known from the German utility model G 87 06 668, with a circular vapor opening in the upper corner area of the furnace muffle is provided in the muffle wall, on which a pipe flange is placed.
  • a pipe flange is placed at this Pipe flange.
  • the fan drive drives one through the cover part in the suction housing protruding output shaft, the two Wears fan wheels.
  • the object of the present invention is an oven according to the preamble of claim 1 to simplify the design with simple means and thus to make it cheaper.
  • this is achieved in that in an oven according to the preamble of claim 1 of the fan motor between the two fan wheels in arranged in the suction housing and held on a partition between the two suction chambers.
  • this is the distance between the cooling air fan wheel from the hot vapors enlarged, which makes this fan wheel cheaper can be designed.
  • the arrangement of the fan motor between the two fan wheels a better and easier mounting of the fan motor and thus a smoother running of the fan wheels possible.
  • the Arrangement of the fan motor in terms of flow behind the cooling air fan wheel for this an undisturbed intake of the cooling air with a large free intake cross-section realized. This can also reduce the noise when the cooling air is drawn in become.
  • the blow-out channel is funnel-shaped in the blow-out direction except for the Width of the oven muffle extended.
  • a reduction in the temperature of the vapor-air mixture when leaving the oven can be achieved in particular be provided that air guide means in the region of the blow-out openings of the suction chamber are, which means that the vapors over substantially the entire width of the exhaust duct is blown out mixed with the cooling air.
  • An oven has an oven muffle 1 which is open at the front and which is articulated by an articulated one Door is lockable.
  • the oven muffle 1 are known heating elements assigned to heat the cooking space. Furthermore, the oven muffle 1 is surrounded from a known housing of the oven (not shown). Above one Cover wall 3, an oven insulation 5 is arranged, which essentially on all sides Oven muffle 1 surrounds. There is a vapor opening in the top wall 3 of the oven muffle 1 7 formed in which a metallic filter housing 9 is held.
  • the filter housing 9 has a cup-shaped housing base 11 and an associated one Housing cover 13 on. In the filter housing 9 is a metal mesh serving as a filter 15 arranged.
  • the housing base 11 and the housing cover 13 have suitable Openings for pulling the vapors out of the oven muffle 1 through the filter 15 on.
  • Above the oven insulation 5 of the oven muffle 1 is a multi-part Fan unit 17 supported.
  • the base plate 19 is on the oven insulation 5 or attached to the housing of the oven muffle 1.
  • Has in the area of the vapor opening 7 the base plate 19 a suitably pulled down base plate pot 20 with corresponding Intake.
  • the housing cover 13 is on the base plate pot 20 the filter housing 9 attached.
  • On which is funnel-shaped in the direction of flow widening base plate 19 (FIG. 2) sits a correspondingly designed air shaft hood 21 (Fig. 1). in the air chamber formed between them is vertical standing a fan motor 23 known per se with a motor shaft 25.
  • the spiral housing 27 has first centering pins 29 and second centering pins 31.
  • the first centering pins 29 of the volute 27 sit in corresponding openings in the base plate 19.
  • the second Centering pins 31 of the spiral housing 27 are seated in corresponding openings in the air shaft hood 21.
  • Through the spiral housing 27, which sits tightly on the base plate 19 is in the area of the vapor opening 7 a vapor suction chamber which is only open at the front 33 formed (Fig. 1, 2).
  • the fan motor 23 there is a cooling air suction chamber in the air shaft hood 21 35 formed. Both suction chambers 33 and 35 open into a front open and expanding funnel-shaped blow-out channel 36, the top and bottom through the Base plate 19 and the manhole cover 21 is limited.
  • the air shaft hood 21 has the circular cooling air intake opening 28 which is limited by a chamber ring 37. The one facing the sucked cooling air The end face of the ring 37 is designed to be rounded in terms of flow technology.
  • an axial fan 39 for sucking in the heated cooling air between the The housing of the oven and the oven muffle 1 flows.
  • the axial fan wheel 39 there is a radial fan wheel 41 on the motor shaft 25 of the fan motor 23 attached.
  • the suitably dimensioned radial fan wheel pulls 41 out of the oven muffle 1 through the filter 15 warm vapors Air into the volute 27 (arrows in Fig. 1).
  • the vapor then becomes essentially horizontally from a vapor outlet opening 43 of the spiral housing 27 into the outlet duct 36 pressed.
  • the axial fan 39 draws heated cooling air into it Suction fan housing 19, 21 and presses it past the fan motor 23 into the exhaust duct 36 (arrows in Fig. 1).
  • the cooling air essentially flows around the volute casing on all sides 27 to cool it down.
