Definitions

  • the present invention relates to a food warming device of the plate type, particularly suitable for cooking and/or warming sandwiches, toasts, piadinas, small pizzas, garlic bread, vegetables and the like.
  • Conventional food warming devices of the plate type substantially comprise a frame which supports a first plate which forms a first cooking surface and a second plate which forms a second cooking surface which is associated with the frame by articulation means.
  • the articulation means are generally constituted by hinges and/or tubular guides and allow the second plate to face the first one in order to form a cooking space in which the food is placed.
  • the cooking space is delimited in a downward region by the first plate and in an upward region by the second plate and is open along its perimeter.
  • One or more electric resistors associated with each plate and supplied by a power supply unit heat the food.
  • One of the main drawbacks of the described conventional devices is that they have a high and undesirable heat loss. This is due to the fact that the cooking space is not closed.
  • Another drawback is the low efficiency of the device, which again is caused by the fact that part of the electric power used to supply the electric resistors is lost into the environment as heat and is therefore not used for cooking.
  • Another drawback is the poor hygiene that the device provides for the food during its cooking and/or warming. Since the cooking space is open laterally, it exposes the food to possible contact with contaminants or unintended objects. Disclosure of the Invention The aim of the present invention is to overcome these drawbacks. Within this aim, an object of the invention is to provide a device which allows to minimize heat loss during the cooking and/or warming of the food.
  • Another object of the invention is to provide a device which allows, in equal conditions, to reduce the cooking time of the food with respect to conventional devices.
  • Another object of the invention is to create a closed environment in which the food is placed so as to prevent it from making contact with foreign matter.
  • Another object of the present invention is to provide a device which allows to filter the fumes produced by the cooking process.
  • Another object of the present invention is to provide a device which allows to increase, with respect to conventional devices, the efficiency of the cooking and/or warming process in terms of energy saving and cooking time.
  • ⁇ a frame which supports at least one first plate which forms a first cooking surface
  • At least one second plate which forms a second cooking surface and is associated with said frame by articulation means adapted to arrange said first and second plates so that they face each other in order to form a cooking space in which the food is placed;
  • ⁇ means for heating at least one of said at least one first plate and said at least one second plate; characterized in that one or more walls are provided which are adapted to close the cooking space along its perimeter.
  • the provision of a substantially closed cooking environment allows the device to operate also as a conventional oven, thus extending the range of use of the device.
  • Figure 1 is a perspective view of the food warming device according to the present invention.
  • Figure 2 is a side view of the device of Figure 1;
  • Figure 3 is a side view of some components of the device of Figure 1;
  • Figure 4 is a side view of a second embodiment of the device according to the present invention;
  • Figure 5 is a sectional side view of a third embodiment of the device of the present invention. Ways of carrying out the Invention The food warming device according to the present invention is shown in
  • Figure 1 where it is generally designated by the reference numeral 1, and comprises a frame 2 which supports at least one first plate 3 which forms a cooking surface 4 and at least one second plate 5 which forms a second cooking surface 6.
  • the second plate 5 is associated with the frame 2 by articulation means, generally designated by the reference numeral 7, which are adapted to arrange the two plates 3 and 5 so that they face each other, as shown in dashed lines in Figure 2, in order to form a cooking space 10 in which a food V is placed.
  • the device further comprises means for heating at least one of the plates 3 and 5, which are generally designated by the reference numeral 8 and are shown in detail in Figure 3.
  • the food warming device 1 is provided with one or more walls 9 which are adapted to close, along its perimeter, the cooking space 10 in which the food V is arranged.
  • the walls 9 are rigidly coupled to the plate 5 by means of protruding elements 11 which are rigidly coupled to a housing 13 fixed to the second plate 5 and mate with a guiding slot 12 formed in each side wall 9.
  • Such sliding coupling allows the walls 9 to move freely in a direction 14 which is substantially perpendicular to the second cooking surface 6. This allows the second plate 5 to approach the first plate 3 until it makes contact with it, adapting the height 15 of the cooking space 10 to the dimensions of the food V and ensuring its perimetric closure.
  • the protruding elements 11 can be rigidly coupled to each side wall 9 and the slots can be formed in the housing 13.
  • the walls 9, as described above, may be rigidly coupled to the frame 2 instead of being coupled to the second plate 5.
  • each wall 9 is of the elastic type in order to allow the walls 9 to first descend under the weight of the second plate 5 and then rise to return into the initial position.
  • the side walls 9 may be constituted by laminar elements which are elastically and telescopically coupled to each other, or only part of the side walls might be movable along the direction 14.
  • the walls 91 are fixed to the housing 13a, while the plate 51 is associated with the housing 13a by guiding means 35 which allow it to move in a substantially vertical direction 36.
  • each guiding means 35 is constituted by a tubular guide 38 which is rigidly coupled to the housing 13a and with which a ring 39, monolithic with the plate 51, is coupled.
  • the invention provides for the presence of a device, not shown, which compensates for the weight of the plate 51 so as to prevent it from crushing, under its own weight, the food V. In this case, therefore, it is the plate 51 that descends, varying the height 151 of the cooking space by gravity until it touches the food V.
  • the articulation means 7 comprise means for adjusting the distance between the two plates 3 and 5 which are constituted by two tubular elements 15, which are arranged substantially at right angles to the first plate 3, and by two hinges 16 which form a rotation axis 17 which is substantially perpendicular to the axis 18 of each tubular element 15.
  • each hinge 16 as shown in detail in Figure 1, has a first annular element 19 which is slidingly coupled to the tubular element 15 and a second element 20 which is rigidly coupled to a support 21 which belongs to the housing 13.
  • each tubular element 15 is replaced with a corresponding number of guiding slots 24 formed in the frame 2a, with which a corresponding number of protruding pins 25 which belong to the support 21a rigidly coupled to the housing 13b are coupled.
  • the coupling of the protruding pin 25 and the guiding slot 24 allows the rotation of the second plate 5 in the direction designated by the reference numeral 26 and its vertical sliding in the direction designated by the reference numeral 27, so as to place the second plate 5 into the position shown in dashed lines.
  • the heating means 8 they are constituted by a plurality of electrical resistors 28, shown in detail in Figure 3, which are arranged in contact with each plate 3 and 5 and are supplied by a respective power supply unit, not shown, which is connected to the electric mains.
  • first plate 3 has lateral shoulders 30 which allow to increase the radiating surface, thus increasing heat exchange and therefore the efficiency of the cooking/warming process.
  • the user U after placing the food V on the first plate 3, by acting on the handle 29 which is rigidly coupled to the housing 13, turns the second plate 5 until it lies parallel to the first plate 3 and at the same time lowers it so as to vary the distance between the two plates 3 and 5 and adapt it to the food V.
  • the side walls 9, by contrasting against the frame 2, form a closed environment inside which the food V is cooked and/or heated.
  • the fumes F produced during the cooking process are evacuated and released into the environment, as shown in detail in Figure 5, by means of one or more openings 29 which are preferably but not necessarily formed in the upper part of the housing 13a, after being filtered by means of the filtering element 30.
  • an extractor unit whose inlet is located proximate to the openings 29 and whose outlet is connected to a duct dedicated to fume evacuation.
  • the device according to the invention is provided with a locking device 37, shown in detail in Figure 2, which allows the user to set in advance the distance between the two plates 3 and 5 during cooking.
  • Said device is preferably but not necessarily constituted by a clamp 33 which is slidingly coupled to the tubular element 15, with which it is rigidly coupled by acting manually on actuation means which are constituted by a locking knob 34. Once it has been fixed to the tubular element 15, the clamp 33 blocks the vertical sliding of the hinge 16 in the chosen point, preventing contact between the second plate 5 and the food V, thus converting the device into a conventional electric oven.
