Definitions

  • the invention relates to a furnace for the heat treatment of Food, with a housing enclosed heated furnace chamber, which can be closed by means of a door is.
  • Such furnaces are basically with one or more Provide door wings that are pivotally attached to the housing and can be opened and closed using a door handle.
  • the open door panels are often a hindrance and give over cause burns, as the door panels are covered by the temperatures of up to 250 ° C and can be more heated.
  • the object of the invention is therefore an improved To create furnace that has the disadvantages of the prior art avoids, especially the risk of injury from hot Door leaf reduced during loading and unloading of the furnace and if possible better use of space even in confined spaces Conditions.
  • this object is achieved in a furnace according to the type mentioned solved in that the door at least has a sliding wing.
  • the at least a wing arched outwards.
  • At least one wing in an alternative Execution of the invention also up or down in the housing can be designed retractable.
  • the Door two wings that can be retracted into the housing.
  • the two are Wing over a joint line set back inwards a seal can be sealed against each other.
  • the two wings complement each other to form an exterior convex surface and are over a joint line a seal can be sealed against each other.
  • the furnace chamber is preferably in the essentially cuboid and the door on one narrow front surface provided.
  • the at least a wing by means of a frame, preferably by means of rollers, slidably guided on profiles on the housing.
  • This measure can reduce the energy consumption of the furnace and at the same time the temperature on the outside of the Glazing can be lowered so far that even in continuous operation there is no risk of injury when touching the glazing is.
  • the Double glazing can be designed so that a front disc and a rear disc with a central one Frame connected and sealed in a suitable manner.
  • the frame can do all the parts necessary for the sliding guide can accommodate or can all parts necessary for sliding guide attack the frame without risking damage to the Glass panes exist.
  • the with at least one wing with its frame in the profiles Play performed with an inner surface facing the wing the profile an elastic contact surface is provided and the inflatable seal on a wing facing External surface of the housing is provided.
  • the frame is on the Profiles run with play and by moving towards sealing the furnace chamber against a circumferential seal lockable.
  • Fig. 1 an oven according to the invention is shown in simplified form and designated overall by the number 10.
  • a cuboid oven chamber 12 Inside a housing 18 is a cuboid oven chamber 12 provided, the front face 32 the Represents the narrow side and the side surfaces 33, 35 the larger, i.e. form longer boundary surface of the furnace chamber 12.
  • slide-in guides 22 On the side faces of the furnace chamber 12 are slide-in guides 22 provided, into which a plurality of furnace plates 20 are inserted can be.
  • These furnace sheets 20 are normally of the type Size standardized and have a width of 40 cm and a Depth of 60 cm. As already mentioned, the arrangement is so made that the furnace sheets 20 with their narrow end face can be inserted into the slide guides 22.
  • a Fan 24 arranged, which is driven by a motor 26 and serves to circulate the furnace atmosphere.
  • the fan 24 is on the suction side a central suction opening is connected to the furnace chamber 12 and on the pressure side with the furnace chamber 12 via side supply air openings, Slots or the like connected.
  • the furnace chamber 12 is turned forward by a convex exterior arched door 14 completed a single wing 16 comprises, in not shown in Fig. 1 in correspondingly curved guides on the top and on the Bottom slidable to the right into the housing 18 and is completely retractable in the housing 18.
  • the right front surface 19 of the housing 18 can, as in Fig. 1 shown, depending on the desired design with a slight Be slanted or parallel to the back wall be trained.
  • the necessary ones are advantageous Controls for controlling the furnace included in it.
  • wing 16 in sliding guides is movably guided on the top and bottom and in the closed position by an inflatable seal 30 is sealable so that the furnace chamber 12 completely is sealed to the outside.
  • the wing 16 comprises a peripheral frame 34, on the Front surface of a glass sheet 36 and one on the rear surface Glass plate 38 is attached.
  • the frame 34 forms with the two Glass panes 36, 38 a completely closed composite, the glass panes 36, 38 with suitable sealing elements are connected to the frame 34 and sealed to it.
  • the frame 34 is within the upper profile 40 and the lower profile 42 with play is guided to be as simple and cost-effective as possible To allow construction.
  • the pressure of the wing 16 against the elastic contact surfaces 48, 49 is in the closed position shown in FIG. 2 by a inflatable seal 30 reached on the front surface of the Housing 18 completely around the opening of the furnace chamber 12 is arranged all around.
  • this inflatable seal 30 with a fluid pressure acts, so that on the one hand a seal of the furnace chamber 12 is reached on the door side and on the other hand the wing 16 is held securely in the closed position without this additional locking measures must be taken.
  • the displacement of the wing 16 in the guides can be done manually can be carried out with a handle or automatically, why appropriate drive options with a cable Gear motor or the like can be provided.
  • the curvature of the wing 16 inwards has the additional Advantage that a reflection of heat to the furnace chamber 12 out is supported, which is additionally supported by a reflective Coating on the inside of the glass pane 38 is supported can be.
  • FIG. 3 Such a modification is shown in FIG. 3 and overall designated with the number 60. Again, door 64 is on the narrow front surface of the furnace.
  • the door 64 is not a single wing 1 but consists of two wings 66, 67, which in the middle at their joining line 68 via an intermediate one Seal 70 in the closed position shown in FIG. 3 rest tightly against each other.
  • Both wings 66, 67 are convex arched outwards and have at their joint line 68 mutually parallel end faces, which over the seal 70th are mutually sealable.
  • Both wings 66, 67 can sideways, as indicated by the dashed lines 72, 73, moved into the housing and completely sunk into it. If necessary, the fan 74 can move a little to the rear be arranged offset, as can be seen from Fig. 3.
  • FIG. 8 a dot-dash line is shown in FIG further shape of the door 84 according to the invention indicated.
  • the door 84 in turn comprises two convexly curved wings 86, 87, which are curved such that the two Wing 86, 87 to an overall convex outward Add area.
