Definitions

  • the present invention relates to an infrared oven for heating and / or keeping food warm, the housing of which has an oven door hinged along the lower edge and the interior of which has a grate that can be pulled out or pushed in to place at least one food container, and one below and one above the grate arranged, rod-shaped infrared radiator.
  • Infrared ovens for baking, toasting, roasting and roasting or for heating prefabricated, chilled or frozen foods or for keeping prepared meals warm are known in a large number of different embodiments. These embodiments make insufficient use of the economic advantages of heating with infrared radiation because the radiation emitted by the radiation source usually diverges greatly and therefore only impinges on the material to be heated to a lesser extent and because the majority of the infrared radiation comes from the Surface of the material to be heated is converted into heat. In order to avoid excessive browning or even burning of the surface layers, the radiation source and the furnace are therefore usually dimensioned for weak heating with relatively poor efficiency. These known embodiments also have the disadvantage that the interior of the oven we is difficult to access due to the compact construction, which increases the risk of painful burns for the operator.
  • the present invention was therefore based on the object of providing an infrared oven which is economically advantageous, which can be used for a large number of different applications and which is user-friendly.
  • this object is achieved with an infrared oven of the type mentioned at the outset, which is characterized in that, in order to generate infrared radiation which strikes the grate practically perpendicularly, the bottom and top surfaces are bent in cross section to form a cylindrical concave mirror and each infrared -Heater is arranged practically in the focal line of the concave mirror of the associated floor or top surface, that for warming up without burning and for keeping warm without drying out the dishes, a program circuit with a first switch for selecting the heating periods and with a second switch for setting the operating time is provided is and that to prevent the risk of injury when setting and removing the food containers, the grate is slidably mounted in the transverse direction of the interior and is connected to the oven door by means of articulated rods.
  • the cross-sectional shape of the bottom and top surfaces and the arrangement of the infrared emitters relative to these surfaces mean that the infrared radiation strikes the grate or the material placed on the grate unimpeded and practically perpendicular.
  • most of the radiation energy is used for heating Well supplied and strikes at an angle at which the radiation is optimally absorbed.
  • Switching on the infrared emitters during an operating period with selectable heating periods enables the heat generated on the surface of the material to be heated to penetrate into the material without the surface burning due to overheating.
  • the mechanical connection between the oven door and the sliding grate means that when the door is opened, the grate together with the goods placed is pulled out of the oven interior and is accessible without hindrance, which simplifies the operator's work and in particular significantly reduces the risk of burns.
  • the infrared oven shown in FIGS. 1 and 2 has a housing 10, the front of which is provided with an opening 11 which forms the access to the interior 12 of the oven.
  • the interior of the furnace is enclosed by two side walls, of which only one side wall 13 can be seen in the figures, a rear wall 14 and a bottom and a top surface 16 and 17, respectively.
  • the bottom and the top surface have a bend 18 and 19 which is parabolic in cross-section and runs in the longitudinal direction of the furnace interior, downwards and upwards.
  • the deflection is a rod-shaped infrared radiator 21, 22 is arranged, which is held in (not shown) sockets, which are fixed in the side walls.
  • All walls of the furnace interior are highly polished or have a mirror finish.
  • a horizontal guide rail 23 is attached to each side wall, which two guide rails are provided for placing and moving a grating 24.
  • An oven door 26 is articulated on the lower horizontal edge of the opening 11.
  • An articulated rod 27 is provided on both sides of the oven door, which form a movement connection between the oven door and the grating. (The grating and the articulated rods are not shown in FIG. 1 for the sake of clarity.)
  • a glass pane is preferably inserted into the oven door, through which the material to be heated can be observed during the warming up.
  • two electrical switches 31, 32 are arranged on the front wall of the housing 10, by means of which the ratio of the switch-on to switch-off time (heating time to pause time) of the infrared radiators during a heating period and the total operating time are set.
  • Two signal lamps 34, 35 which are provided to indicate the operation or the expiry of a switched-on operating period, are also mounted adjacent to the switches.
  • the space between the furnace walls and the housing is filled with electrical lines, switching elements for the infrared radiators and with insulating material 33.
  • a connection (not shown) for the household power supply is provided on the rear of the housing.
  • the oven door 26 is opened first.
  • the grating 24 is partially pulled out of the furnace chamber 12 by the articulated rods 27, so that the material to be heated can simply be placed on the grating.
  • the oven door is closed, the grille and the items to be heated are pushed into the oven space by the hinged rods. Then, with the help of tables or empirical values, the optimal heating period and the entire operating time for the goods to be heated are set and the infrared emitters activated.
  • the radiation reflected from the bottom and top surfaces is practically vertically raised or reflected below in the part of the furnace space occupied by the material to be heated.
  • the corresponding signal lamp lights up When the oven door is opened, the grate is then pulled out of the oven space at the same time, so that the heated goods placed on the grate can be handled without touching hot oven parts.
  • a practically tested embodiment of the infrared oven described has a usable oven interior of 30 cm long, 20 cm deep and (above the grating) 7 cm high.
  • Each of the two rod-shaped infrared emitters has a power consumption of 500 watts.
  • the oven door can be swiveled by 60 ° when opening, the grille being pulled out about 12 cm from the oven.
  • the heat period switch 31 enables the heating time for every 60 seconds selectable time period of 15 sec or 30 sec or 45 sec to interrupt or to heat without interruption.
  • the operating time switch 32 is provided for setting the total operating time.
  • the infrared oven is particularly suitable for heating prepared dishes, whereby frozen "hot dogs", apple strudel or cheese cake with a setting of the heat period switch to 15 seconds interruption between successive heating times of 60 seconds after a total operating time of 5 to 6 minutes are heated consistently and got an appetizing brown crust. The same result was achieved for half of the total operating time for the same dishes when they were placed in the oven when thawed.
  • An obvious modification of the described embodiment relates to the signal lamps, one of which indicates the operation of the furnace can be dispensed with without disadvantage and the other which indicates that a set operating time has expired can be replaced by an acoustic signal generator.
  • the latter is particularly advantageous in embodiments which are intended for installation in Loka len or common rooms are provided, where acoustic signals are perceived better than optical signals.
