Definitions

  • the present invention relates to an oven with a vapor opening in a muffle wall, in the area of which a filter or a catalyst is arranged in a filter housing, and with a suction fan that pulls the vapor through the filter out of the oven muffle and presses it out of the oven.
  • Such an oven is generally known, with a simple assembly of the filter or catalyst housing without damage to the muffle wall in the area of the vapor opening being problematic.
  • screw connections or unfavorable contact points between the filter housing and the enamelled muffle wall lead to flaking of the enamel when the oven muffle is thermally stressed.
  • the assembly of the filter housing and the removal of the filter by an operator is only possible with great difficulty.
  • the object of the present invention is to improve an oven according to the preamble of claim 1 in such a way that the mounting and mounting of the filter housing does not impair the properties of the oven.
  • a mounting part is arranged outside and the filter housing inside the muffle wall of the oven muffle in the area of the vapor opening, and in that the filter housing is held on the mounting part.
  • a bottom plate of a blow-out duct of the suction fan serves as the mounting part.
  • This is particularly simple in terms of production technology and also leads to a tight connection between the filter housing and the blow-out duct. A disadvantageous escape of vapors in the space between the oven muffle and the oven housing is avoided with simple means.
  • an additional sealing hose which connects the vapor opening with a suction opening of the exhaust duct, can be omitted.
  • the filter housing advantageously has a housing base and a housing cover, the housing cover being fastened to the mounting plate, and the housing base being easily detachably held on the housing cover.
  • this enables a simple and tight connection between the filter housing and in particular the exhaust duct of the suction fan.
  • the operator can easily replace the filter or the catalyst.
  • the tightness of the entire arrangement is also increased, since the housing cover lies tightly in the edge area of the vapor opening on the muffle inner wall and the housing base, which is movable relative to the housing cover and provided with suitable sealing surfaces, provides the tight connection to the housing cover.
  • the housing base is pot-shaped.
  • the housing cover has special holding means for loosely hanging or preassembling in the vapor opening of the muffle wall of the oven muffle.
  • a stove 1 with a hob has a metallic housing 3 which encloses an oven muffle 5. This is covered in a manner known per se with a heat insulation material and can be closed on its front side with an articulated oven door 7.
  • the door 7 consists of a trough-shaped metallic door floor 9, in which a viewing window 11 is held. In the front region of the door 7, a front plate 13 spaced apart from the viewing window 11 is fastened to the door base 9. Between the door base 9 and an oven flange 15 of the oven muffle 5 there is arranged a seal 17 which essentially covers the entire muffle opening.
  • an upper-level heating element 19 is shown, which is fastened below a top wall 21 of the oven muffle 5.
  • a vapor opening 23 is also provided in the top wall 20 (FIG. 1).
  • the vapor opening 23 is tightly connected to a blow-out duct 27 via a funnel-shaped connection piece 25 which opens out into the open above the door 7 in the front area of the cooker 1.
  • a motorized fan 28 for sucking air or vapors out of the oven muffle 5 as required.
  • the operation of a control unit 29 for controlling all operating modes of the cooker 1, such as in particular the baking operation, a pyrolytic self-cleaning operation or cooking with an integrated microwave, is possible via several handles 30 held in the front area of the cooker 1.
  • a cover plate 31 is tightly connected on the circumferential side to its annular edge.
  • the cover plate 31 has a plurality of centrally arranged vapor openings (not shown) and in the region of the vapor opening 23 is also tightly connected on the circumference to the outside of the top wall 21 of the oven muffle 5.
  • a cup-shaped filter housing 33 with vapor openings (not shown) is fastened in a removable manner in the bottom thereof by means of a bayonet catch, not shown.
  • a filter which is not described in more detail and is known per se, is arranged for cleaning the vapor-containing air sucked out of the oven muffle 5 (FIG. 1).
  • FIGS. 2 and 3 The second exemplary embodiment shown in FIGS. 2 and 3 is described below. For simplicity, only a small section of the cooker is shown.
  • a circular vapor opening 43 is provided in an enamelled top wall 41 of the oven muffle.
  • a heat insulation 45 known per se is arranged outside the top wall 41.
  • a fan base plate 47 of an otherwise not shown suction fan with a blow-out duct according to the first exemplary embodiment according to FIG. 1 is seated on the heat insulation 45 arranged base plate screw holes 51 (Fig. 3).
  • a two-part, metallic filter housing 53 is held in the vapor opening 43, in which a metal knitted fabric serving as a filter 55 is arranged.
  • the filter housing 53 consists of a filter bowl 57 serving as a base part and a filter cover 59 which can be connected to it.
  • the filter cover 59 is plate-shaped with a centrally formed cover cover 61.
  • the cover scoop 61 corresponding to the base plate vapor opening 49 corresponding cover vapor openings 63 and to the base plate screw openings 51 corresponding thread impressions 65 are provided.
  • the cover cover 61 can be inserted into the vapor opening 43 of the cover wall 41.
  • mounting tabs 69 of the filter cover 59 are to be inserted into corresponding notches 67 in the cover wall 41 (FIG. 3).
  • the filter cover 59 is rotated and engages behind the cover wall 41 with its mounting tabs 69 in the area of support surfaces 71.
  • the filter cover 59 is screwed to the fan base plate 47 via the thread impressions 65 and the base plate screw openings 51. This creates a vapor-tight connection between the fan base plate 47 and the filter cover 59.
  • the filter bowl 57 of the filter housing 53 has shaped embossments 73 which are uniformly distributed on the circumference and which facilitate rotation of the filter bowl 57 during its assembly or disassembly.
  • a pot flange 77 is interrupted at opposite points by flange notches 79.
  • the pot flanges 77 each have a locking embossment 81 on one of their end sections.
  • resilient latching arms 83 with spherical embossments 85 formed on the upper side thereof are provided in two opposite notches 82 of the filter cover (FIGS. 2, 3).
  • the filter bowl 57 lies with an annular sealing edge 87 on the underside of the filter cover 59.
