  • the present invention relates to an oven muffle.
  • the reference technical field of the invention is the one of (household and industrial) ovens for cooking or heating food. More specifically, the technical field of the invention relates to oven muffles, in which steam and water can be introduced into the cooking chamber through suitable ducts in order to perform steam cooking and cleaning cycles, respectively.
  • the invention further provides the presence of an inner wall inside the cooking chamber so as to create a pre-chamber, which accommodates a fan.
  • the invention deals with problem concerning how the ducts are arranged relative to the pre-chamber.
  • ⁇ As it is known, household or industrial ovens for cooking or heating food comprise a particular inner structure known as muffle, which defines the cooking chamber. On the outside of the muffle there is an outer frame and between the muffle and said frame there is an air gap where the devices used for the correct operation of the oven are arranged.
  • the muffle comprises a plurality of walls connected to one another or directly manufactured as one single piece.
  • the muffle comprises a back wall, a roof wall, a floor wall and two side walls. A front door is added to this structure.
  • the door is movable (usually hinged to a side wall or to the floor wall) between a first position, in which it closes the cooking chamber in order to reduce the dispersion of cooking heat, and a second position, in which it allows users to access the cooking chamber.
  • a fan which is coupled to one of the walls, usually the back wall, and is configured to create a forced movement of air in the cooking chamber.
  • a suitable inner wall which faces and is spaced apart from a wall supporting the fan, so that the cooking chamber is divided into a first chamber between the cooking chamber and the inner wall (which houses the fan) and a second chamber beyond the inner wall (which defines the usable portion of the cooking chamber).
  • the two chambers can communicate with one another in different ways. For example, openings can be provided in the central part of the wall or in the peripheral parts.
  • each duct has a first delivering end of its in the cooking chamber and a second supplying end on the outside of the cooking chamber, supplied with steam and water, respectively.
  • the steam is generated by a small electric boiler, which heats part of the water present in the tank, while part of the water is supplied, when requested, to the relative duct by a suitable pump.
  • the object of the invention is to provide an oven muffle provided with ducts for introducing steam and water into the cooking chamber, which is capable of offering a new and alternative solution.
  • the invention relates to a novel oven muffle, wherein said muffle comprises a cooking chamber with a substantially box-like shape and with a front opening (as known).
  • said cooking chamber is delimited by:
  • the muffle according to the invention further comprises:
  • the steam source and the water source supplying the first and the second duct can be independent or can comprise a common tank, which can be refilled with water and is located on the outside of the cooking chamber.
  • both the first and the second duct comprise a first end inside the cooking chamber and a second end on the outside of the cooking chamber, which is directly or indirectly connected to the steam and water sources.
  • the main aspect of the invention relates to how the two ducts enter the cooking chamber and where the corresponding first steam and water delivering ends are located relative to the inner wall.
  • the first end of the first steam delivering duct is located inside the first chamber between the wall of the cooking chamber and the inner wall.
  • the muffle preferably comprises a fan accommodated in said first chamber, where steam is delivered, so as to force steam to flow from the first chamber to the cooking chamber beyond the inner wall.
  • the inner wall preferably comprises at least one opening to allow steam to flow from the first to the chamber of the cooking chamber.
  • the first end of the second water delivering duct is preferably located inside the second chamber so as to directly deliver water beyond the inner wall.
  • Both ducts enter the chamber by going through the same wall, namely the back wall, facing the inner wall.
  • the second duct in this case, necessarily has an extension that is such as to go beyond the first chamber and reach the second chamber, going through a hole obtained in the inner wall.
  • the invention provides the presence of a single flange assembly, which supports both ducts in place astride the opening and seals the latter.
  • the flange assembly preferably comprises an outer flange integral to the ducts and configured to be coupled to the opening on the outside of the muffle.
  • the joining of the ducts to the outer flange can be directly obtained during the production phase, thus creating one single piece, or the ducts and the flange can be connected through welding.
  • the outer flange is preferably provided with holes, which, in use, are in the area of holes made in the wall of the muffle, so that the flange and the muffle are coupled through threaded bodies.
  • the flange assembly preferably comprises an inner flange configured to be coupled to the opening inside the cooking chamber and provided with holes to receive the aforesaid threaded bodies and with holes for the passage of the ducts.
  • an inner plate or seal and an outer plate or seal are provided in the area of the opening between the wall of the muffle and the inner and outer flanges.
  • Said plates or seals are provided with holes for receiving the threaded bodies (which, hence, pack the entire flange assembly together) and with holes for the passage of the ducts.
  • the inner and outer flanges are preferably made of a metal material.
  • the plates or seals are preferably made of a metal material or rubber.
  • the invention also applies to an oven comprising a muffle as described above.
  • figure 1 shows an example of an oven muffle according to the invention indicated, as a whole, with number 1.
  • Said muffle 1 defines a cooking chamber 2 having an opening and delimited by a back wall 3 opposite the opening, a roof wall 4, a floor wall 5 and two side walls 6, 7.
  • the muffle of figure 1 is a muffle configured to deliver steam to the cooking chamber, in order to cook food with steam, as well as water to perform cleaning cycles.
  • the muffle comprises a water loading cup 30 accessible from the front and, at the back, a water tank connected to a small boiler for the generation of steam as well as a suction pump.
  • FIG 1 the back wall 3 is not visible or is only partly visible due to the presence of an inner wall 20 facing and spaced apart from the back wall 3.
  • the inner wall 20 divides the cooking chamber into a first chamber between the back wall 3 and the inner wall 20 and a second chamber beyond the inner wall 20 towards the opening of the muffle 1.
  • the references 25 of figure 1 indicate possible concentric circular openings, which are a mere example of a possible fluid connection between the two chambers.
  • Figure 2 shows a different perspective view of the muffle of figure 1 , in which the inner wall 20 was removed.
  • Figure 2 shows a detail of the back wall 3 indicated with III, a portion that is shown in figure 3 in an enlarged view.
  • number 8 relates to a first duct configured to introduce steam into the cooking chamber and number 9 relates to a second duct configured to introduce water into the cooking chamber.
  • number 28 relates to a fan and, as shown, the ducts and the fan are associated with the same back wall 3.
  • the invention does not deal with how the ducts 8 and 9 are supplied with steam and water, since this subject-matter is known to a person skilled in the art.
  • the figures show an embodiment of the invention, namely they show how both ducts 8, 9 enter the cooking chamber 2 going through a common opening 10 obtained, in this example, in the back wall 3 of the muffle 1.
  • the opening is a slot and the ducts 8, 9 are arranged at the ends thereof.
  • Number 11 of figure 3 identifies the flange assembly arranged in the area of the opening 10, in which one single flange assembly supports both ducts 8, 9 in place and seals the opening 10.
  • how the ducts cooperate with the wall 3 is an important, though not primary aspect, since the primary aspect is the relationship between the ducts and the inner wall 20.
  • FIG 4 shows a cross section view of the detail of figure 3 , in which the cross section plane is parallel to the side walls of the muffle.
  • This cross section shows the components making up the flange assembly 11 as well as the extensions of the ducts in the cooking chamber.
  • the first end 23 of the first duct 8 (from which steam is dispensed) is located inside the first chamber 21 between the back wall 3 and the inner wall 20, whereas the first end 24 of the second duct 9 (from which water is dispensed) is located inside the second chamber 26 beyond the inner wall 20.
  • both ducts enter the cooking chamber 2 by going through the same wall 3 facing the inner wall 20, however only the second duct has an extension that is such as to go beyond the first chamber 21, going through a hole 27 made in the inner wall 20.
  • the flange assembly 11 comprises:
  • the outer flange 12 is manufactured as one single piece together with the ducts 8, 9, whereas the inner flange 17 and the plates or seals 18, 19 are provided with holes configured to allow the passage of the ducts 8, 9.
  • the fixing in place and the fastening of the flange assembly 11 is carried out by means of threaded bodies 15, 16 coupled to respective holes made in the wall 3 of the muffle, in the flanges 12 and in the plates 18, 19.
