Definitions

  • the present invention relates to a device for treating and preparing Food, the device being a cooking space in which the food is treated or be cooked, a motor-driven fan wheel that is used for circulation serves the cooking chamber atmosphere prevailing in the cooking chamber, a burner which is used for Combustion of a gas-air mixture is used, and a heat exchanger device has a heat exchanger tube device which surrounds the fan wheel.
  • the present invention relates to a heat exchanger device for a such device.
  • a heat exchanger device for cooking devices is for example from DE 197 08 231 A1 known.
  • the heat exchanger device of this prior art has a substantially horizontally arranged combustion chamber, which with a Heat exchanger pipe communicates in which the burned gas-air mixture is fed.
  • the heat exchanger tube runs along the four sides of the cooking space in the direction away from the combustion chamber and returns at the end of the fourth side by means of a cantilevered bend around the same distance parallel to put back the pipe string leaving the combustion chamber.
  • the only heat exchanger tube extends along the combustion chamber to below the cantilevered bend, from where the exhaust gas is discharged to the outside.
  • the present invention is therefore based on the object of a device for Treating and preparing food with a cooking space which is heated by gas firing, in which the heat exchanger device provides significantly improved heat transfer, which is significantly less Makes heating power possible, which means significantly lower exhaust gas losses arise.
  • the heat exchanger tube device at least two pipe strings has, which is continuously around the ventilation wheel essentially in a border extend the fan wheel, it is achieved that on the one hand an optimal flow path is created for the heating gas of the heat exchanger tube device and also a significantly improved heat exchanger function is achieved.
  • the heat exchanger function is advantageously increased by the fact that three Pipe strings are provided, d. H. the heated gas stream is divided into three parts.
  • the three tube strands are advantageously triangular in the tube longitudinal direction arranged.
  • the tubing strands extend essentially along all of them four sides of the cooking space, but not along the burner. This will, on the one hand realized a compact design of the cooking device and on the other hand the possible diameter of the burner chamber increases, creating a better and more complete combustion of the gas-air mixture is achieved.
  • Pipe string preferably all pipe strings have at least one flow deflecting device on. With the help of the flow deflector, the flowing gas from a laminar flow can be converted back into the turbulent flow, so that areas in the middle of the flow get out again and thus the efficiency of the heat exchange process is significantly increased. On the other hand this also creates the advantage that the length of the respective Pipe string can be significantly shortened compared to the prior art.
  • two flow deflection devices are in each pipe string Spaced from each other so that a multiple change in flow from a laminar flow to a turbulent flow to increase efficiency of the heat exchanger is realized.
  • the burner chamber arranged substantially vertically becomes a particularly efficient Combustion of the gas-air mixture achieved. But that is particularly advantageous Flame down in the burner chamber.
  • a guidance of the exhaust gas is made possible such that the gas path in The appliance outside the cooking space can be kept as short as possible.
  • the present invention also has a heat exchanger device for an apparatus for treating and preparing food, the subject Has heat exchanger tube device.
  • the heat exchanger tube device has at least two strings of tubing that are continuous around the fan wheel essentially extend in a border to the fan wheel.
  • FIG 1 is a schematic side view of the structure of an inventive Device 1 for treating and preparing food, in the form of a Combi steamer shown, which has a housing 3. Inside the case 3, a cooking chamber 5 is provided, in which the food to be treated is introduced can be. The front of the cooking chamber 5 is known per se Lockable and openable with a door 7.
  • a radial fan 9 Located behind a substantially vertically arranged air baffle 25 there is a radial fan 9, the structure of which can be clearly seen from FIG.
  • the radial fan 9 is driven by an asynchronous motor 11.
  • the asynchronous motor 11 is arranged behind a rear wall 13 of the cooking space 5 and has a drive shaft 15, which is connected to the radial fan wheel 9 for driving it.
  • a supply air duct 17 is provided in order to adjust the humidity in the cooking chamber 5 which a controllable flap 19 is arranged.
  • a water inlet 21 is also provided, which has a controllable inlet valve 23 has.
  • the water inlet 21 ends in the center area of the fan wheel 9, d. that is, the water to be evaporated is in the center of the fan wheel 9 injected and due to the rotation of the fan wheel 9 radially outwards flung, with part of the water already evaporating.
  • the between that Radial fan 9 and the baffle 5 provided air baffle 25 is used for distribution the air in the cooking space.
  • an outlet 27 is also provided, via which Liquid, especially vapors, can run off and also pressure equalization serves.
  • a heat exchanger device 29 extends around the radial fan wheel 9 is described in more detail below with reference to FIG. 2.
  • the heat exchanger device 29 extends around the radial fan wheel 9 and essentially follows the inner contour of the cooking device 1.
  • the heat exchanger device 29 is fed by a gas firing 31, which has a burner chamber 33.
  • the burner chamber 33 is as out Figure 2 can be seen, arranged vertically. It has a gas inlet 35 through which a gas-air mixture is introduced into the burner chamber 33.
  • a heat exchanger connection 39 is provided, which is connected to two pipe strands 41, which are the heat exchanger device 29 form.
  • the pipe strands 41 extend in a border or loop around the fan wheel 9 and end in an exhaust gas collection and discharge device 43rd
  • Each pipe string 41 has a substantially short first vertical pipe section 45, a first substantially horizontal tube section 47, a second substantially vertical tube section 49 and a second substantially horizontal pipe section.
  • the pipe sections 45 to 51 are over Pipe bend sections 53 connected.
  • the heat exchanger gas moves in the Pipe string 41 in front of the flow deflector 55 essentially according to one Flow profile 57.
  • the laminar Flow 57 swirls as indicated by arrow 58. Then it turns ideally, a steady flow, as is the case with the turbulent flow profile 59 is specified.
  • FIG 2 there are schematically only two flow deflectors 55 in the foremost Pipe string 41 shown. At least two flow deflection devices are advantageous 55 arranged in each of the tubing strings 51, wherein also a further flow deflector 55 in the first horizontal pipe section 47 can be arranged and / or a further flow deflection device 55 can be arranged in the second horizontal tube section 51.
  • FIG 2 schematically illustrated configurations of the flow deflection device 55 in that the back pressure and thus the fan power to be applied can be minimized.
  • the fan can be kept small, which is probably the compact design of the overall device also promotes energy consumption reduced for the operation of the blower.
  • the gas firing 31 is shown schematically in FIG.
  • a substantially circular grid 61 is arranged, and the gas-air mixture, which enters the burner chamber 33 via the gas inlet 35 flows through the grating 61.
  • An ignition device is located below the grating 61 63, which ignites the gas-air mixture and a dashed firing cone 65 forms, which extends vertically downward in the burner chamber 33.
  • the arrangement of the flame cone 65 has the advantage of being essentially complete Combustion of the gas-air mixture, due to the grid itself the flame cone 65 from a large number of individual flames due to the Grid structure of the grid 61 is composed.
  • the present invention thus provides a device for treatment and preparation of foods with a very advantageous gas firing and advantageous switched off heat exchange device created.
