Definitions
- an area of heater is an area of the heater and / or cooking appliance capable of being heated by the means of heat generation when is next to it.
- the present invention therefore proposes to solve a part of less of these drawbacks, by proposing a heater and / or cooking of the type already described, characterized in that the means for producing heat is mobile vis-à-vis the frame and the heating zone (s).
- the means of production of heat can in particular be linked to a support mounted rotating opposite the built opposite the heating zone in order to obtain an easy movement to create and manage heat production means, particularly favorable for a homogeneous distribution of the heat thus produced.
- the means of producing heat may be fitted with at least one element with a radiant surface which can move with it to radiate towards the heating zone.
- the energy source to which the medium is connected heat production will advantageously be a mixture of gases fuel and combustion air, and the means of producing heat will then include at least one burner.
- the apparatus may further comprise a fixed element with a surface radiant opposite which is placed the means of producing heat in a determined position of it to radiate, in this position from the heat generating means, to the heating zone (s).
- the means of production of heat will preferably be placed between the internal enclosure and the enclosure outside of the oven. In this way, the interior of the internal enclosure is heated from the outside and the means of heat production does not interfere the introduction of a container or food to be cooked or heated in the internal oven enclosure.
- these can be substantially concentric and the heat generating device is mounted rotating between them.
- the means of production of heat extends in the direction of the oven depth, that is to say between the bottom and front part of the internal enclosure (in normal position of use). In this way, most of the heating area and the space between the two speakers is heated.
- the energy source to which the heat generating means is connected is a mixture of combustible gas and combustion air, and the means of heat production includes at least one burner supplied by said gas mixture.
- the internal enclosure comprises side walls, a bottom wall, a top wall and a substantially vertical bottom in normal position of use, and the means of producing heat rotates at least 180 ° around the internal enclosure along an axis xx ' perpendicular to said bottom.
- the means of production of heat will be able to rotate around the internal enclosure in order to offer the possibility to perform the cooking function in a fixed position under the lower wall, the grill function in a fixed position above the upper wall, the fan function in mobile position around the enclosure constant speed, and the pyrolysis function in slow rotation around the internal enclosure with maximum heating power.
- the burner can include a row of ignited gas outlets aligned along an axis zz 'parallel to the axis xx', and said outlets for ignited gases can be located laterally on the burner, so that the flames emanating from the burner do not develop towards the internal enclosures and external.
- the external enclosure can be provided a metal plate placed above the upper wall of the internal enclosure, which can then be partly constituted by a material transparent at least to infrared rays, typically glass ceramic material.
- a material transparent at least to infrared rays typically glass ceramic material.
- the means or one of the means heat production can be mounted rotating around an axis yy ' perpendicular to the bottom wall of the internal enclosure. In this way, the heat produced by the means of heat production will be more homogeneous under the lower wall for the cooking function, or above the wall upper for the broiler function.
- the means of production of heat can be provided with at least one element with a mobile radiant surface with him to radiate towards the heating zone.
- the means (s) of production heat can be linked to a means of translational movement allowing to keep it away from the heat zones and / or from it move between several heat zones. In this way, we can avoid to have to move a container or food placed above its area of corresponding heating, which will heat alternately each heating zone. We can also use several means of heat production of different powers (cooking, simmering) move alternatively to heat the same container without having to move it.
- the number of heating zones will be at least equal to two and will be strictly greater than the number of means (s) of heat production. So he can there is only one means of producing heat for two zones of heating or more, said (each) means of producing heat being movable relative to these heating zones to eventually come alternately heat the containers or food placed on these areas.

- Figure 13 is a variant of Figures 1 to 5 in which the means of producing heat is an electrical resistance.
- FIG. 1 An oven 1, equipped with a means 2 for producing heat according to the present invention, is shown in Figure 1.
- This oven 1 includes an internal enclosure 5 made of a good metallic material relatively thin heat conductor such as sheet steel.
- the enclosure internal 5 comprises side walls 6 which are substantially flat and parallel, a bottom wall 8 (called “sole") substantially planar and provided with vents 9 ending in the internal enclosure 5, an upper wall 10 (called vault) in the shape of a dome comprising at least one transparent part 11 infrared rays, typically made of glass ceramic material, and a bottom 12 substantially planar.
- the bottom 12 and the side walls 6, on the one hand, and the bottom wall, on the other hand, are normally respectively essentially vertical and horizontal in normal position of use of the oven 1.
- the bottom 12 is further provided with an elongated opening 13 placed close to the upper wall 10 and the largest dimension of which is parallel to the bottom wall 8.
- the enclosure internal (5) will constitute all or part of a heating zone referenced 14.
- the oven 1 is provided with an external enclosure 17 defining at least part of a frame 18 and arranged around the enclosure internal 5.
- the external enclosure 17 is preferably of generally cylindrical shape circular, and is provided with an upper recess 20 inside which is fixed a metal plate 21 intended to be brought to red by the heat generating means 2 when it is in static position low under the plate 21.
- the internal enclosure 5 and the external enclosure 17 define a space 25 inside which can move the means 2 of heat production illustrated in FIG. 4.
- a front plate 22, substantially annular, enables said space 25 to be closed at the front of the oven.
- the external enclosure 17 further comprises a bottom 23, typically a metal plate parallel to the bottom 12 having substantially the shape of a disk. This bottom 22 is also provided with an elongated opening 24 having substantially the same dimensions as the opening 13 and which is placed slightly above the upper wall 10 of the internal enclosure 5.
- This burner 32 has substantially the shape of a hollow rod extending along the depth of the oven (parallel to the axis xx ') and is provided with at least one combustion rail 33 (see FIG. 5), and preferably two, which are opposite and supplied with a mixture of combustible gases and of combustion air, as shown in Figure 4.
- said means 2 of heat production can rotate on its support 30 around the axis xx ' at least 180 °, and preferably 360 °, between the internal enclosure 5 and the external enclosure 17, thanks to a motor 39 also shown on the figure 4.
- FIG. 3 shows the furnace 1 with the means 2 for producing heat in a fixed position above the upper wall 10.
- This position is also called “grill" position or broiler function because the burner 32 heats the metal plate 21 placed above the means 2 for producing heat and take it red so that it emits infrared rays passing through the transparent zone 11 of the upper wall 10 in order to heat inside the internal enclosure 5.
- food placed at the interior of the enclosure, and in particular close to the upper wall 10 can be grilled.
- FIG 4 shows in detail the system for powering the burner 32 and rotate the support 30.
- the support 30 is hollow and is connected to a pipe 36 inside which circulates air put under pressure by a fan 37, and combustible gas (such as natural gas) supplied downstream of the fan 37 by an injection line 38.
- the support 30 is mounted rotating on its axis xx 'and is connected to motor 39 to using cogwheels 41 and a chain 40.
- the supply system of the burner 32 and the support rotation system 30 are mounted behind the bottom 23. Part of the air supplied by the fan 37 can be deflected by direction of space 25 by a pipe 42 (see Figure 2), and move between the internal enclosure 5 and the external enclosure 17 as illustrated by the arrows T shown in particular in Figures 1 and 2.
- the burner 32 and its arm 30 movable around axis xx '.
- the burner 32 comprises at least one lateral ramp 33 provided with a series of orifices 34 aligned along an axis zz 'parallel to the axis xx'.
- These holes 34 are intended for the passage of ignited gases, the air / gas mixture operating in total air put under pressure by the fan 37.
- the flames preferably qualified as "blue flames”
- they are substantially tangential to the upper wall 10 and parallel to the side walls 6 and bottom 8, this in order to avoid carrying the speakers 5 and 17 in red, while sufficiently heating the heating 14 so that it in turn heats the interior of the internal enclosure 5.
- the means 2 for producing heat can take all possible positions in rotation between the two speakers.
- it can be kept under the lower wall 8 of the enclosure internal 5 ( Figure 2) to heat the lower part of the heating zone 14 (the bottom element of the oven); it's classic cooking.
- the heat released by the heat generating means 2 then passes to the through vents 9, moves vertically by convection inside the internal enclosure 5 according to the arrows T for heating or cooking a food placed inside it, and crosses the vent 13 then the vent 24 to exit behind the oven 1.
- the means 2 for producing heat can also be kept above of the upper wall 10 of the internal enclosure 5 (FIG. 3), and heat the metal plate 21 in order to bring it to red, the infrared as well created then passing through the transparent part 11 of said upper wall 10 to heat the interior of the internal enclosure 5; it's the grill function or broiler performed here by radiation (infrared), then by convection at inside the internal enclosure 5.
- a third function, called “fan heat”, is also proposed, this one being important and unprecedented in this type of oven.
- the support 30 rotates around the axis xx 'thanks to the motor 39 (shown in the Figure 3) which drives it.
- the means 2 for producing heat rotates around the internal enclosure 5 the arrows F (figure 1) to heat the heating zone 14, and flames exit laterally from the ramps opposite 33 by the holes 34 without contact with the speakers.
- This is pyrolysis. For this, we make sure that the temperature inside oven 1 is around 480 ° C by putting the burner 32 at full power, and let the means 2 of heat production at relatively slow speed (less than 1 revolution per minute). We can thus perform a complete pyrolysis in one hour by incineration of fats attached to the internal enclosure 5, while that the same operation takes between two and three hours in an oven traditional electric and consumes more energy.
- Figures 6 and 7 show an alternative embodiment of the means 102 of heat production for an oven 100 (also called “broiler") of identical structure to the oven 1. To facilitate the description, the parts of the oven 100 identical to oven 1 will have the same references.
- Medium 102 of heat production includes at least one blade-shaped burner 45, and preferably three, arranged at 120 ° from each other and mounted (s) rotating (s) on a shaft 46. These blades are supplied with combustible gas and combustion air to create an inflamed mixture.
- each burner 45 comprises at minus a radiant zone 47 of fibrous refractory material of the fiber type randomly braided ceramic. So there is no flame coming out of the means 102 of heat production, since this heats by radiation.
- the feeding and rotation system of this variant of realization is identical to that of the means 2 for producing heat from Figures 1 to 5 but it is fixed inside the recess 20 of the enclosure external 17 replacing the metal plate 21.
- the means 102 for producing heat is constituted by a burner 45a whose surface is completely covered with fibrous refractory material forming a radiant zone 47, and two others burners 45b comprising a peripheral section 49 covered by said refractory material and a central section 48 close to the axis of rotation yy ' not producing heat.
- FIG 9 shows a variant of Figure 6 in which the 102 medium heat production is provided with two burners 45.
- Each of these burners 45 comprises a radiant zone 47 cut into a section central 48 close to the axis of rotation yy 'and a peripheral section 49 of different shape.
- the surface of the central section 48 is very small wide and straight (rectangular shape) while the surface of the section peripheral 49 is triangular in shape widening towards the most away from the axis of rotation yy '. In this way, the distribution of heat is different and progressive from the center towards the end of each blade 45.
- Figure 10 shows another variant of Figure 6 in which the means 102 for producing heat is provided with only one burner 45 whose radiant zone 47 has a triangular shape widening from the axis yy 'of rotation.
- the distribution of heat is different from the variant embodiments illustrated in FIGS. 6, 8 and 9.
- the principle of the broiler thus illustrated in particular by FIG. 7 is relatively simple.
- the means 102 for producing heat described previously is arranged between the external enclosure 17 and the internal enclosure 5, above the upper wall 10, part 11 of which is preferably constituted by a material transparent to infrared rays, typically a ceramic glass material.
- the means 102 of production of heat heats by radiation is rotated by a motor 39 (see FIG. 6) which rotates it at around two revolutions per minute along an axis yy ' perpendicular to the bottom wall 8.
- the distribution of the heat is uniform, allowing for example to grill easily and quickly slices of bread or other food placed on a rack in oven 1.
- the infrared rays will also heat the area of heating 14, and in particular the non-transparent part of the wall superior 10.
- This operating mode can also be adapted to the cooking function by placing the means 102 for producing heat under the bottom wall 8 and rotating it in the same way as previously around the axis yy '.
- the means 102 for producing heat describes and illustrated by figures 6 to 10 can also be applied to small devices heating / and / or cooking appliances such as a vertical toaster, in which case said means 102 for producing heat is placed on the side (s) of the slices to grill and not above.
- FIG. 11 describes an alternative embodiment in which at at least one means 202 for producing heat is arranged in a cooker 200 or in a similar appliance (for example a simple built-in hob).
- This stove 200 includes a rack 205 provided with an upper wall 206 above which a grid is fixed here 208 of known type in this type of device, although a plate full glass ceramic can also be used.
- This grid materializes several heating zones 207 which can be located directly on the grid (by changing the color or appearance of the grid), or on the wall upper 206 (for example by screen printing).
- Production means 202 heat includes a burner 209a of blue flame and of known type connected to a foot 215 itself engaged on a linkage 210 (shown schematically) to form displacement means intended for the make it movable relative to the frame 205 and to at least one of the zones of heating 207.
- a linkage 210 shown schematically to form displacement means intended for the make it movable relative to the frame 205 and to at least one of the zones of heating 207.
- two means of heat generation 202 are shown, each comprising a burner mobile (referenced 209a and 209b). They are arranged so that they can move laterally respectively in two parallel lines referenced K and L.
- this stove 200 is relatively simple, and in particular makes it possible to avoid to have to move heavy containers 212 over each of the zones 207 of the grid 208.
- the burner 209a and / or the burner 209b can translate laterally along the K / L line of each linkage 210 using their respective feet 215, to come and place themselves under one of the containers 212 placed on the grid 208. It is therefore no longer container 212 or the food placed on the rack 208 which is moved, but the means 202 of heat production itself which is put in translation or in rotation by mechanical means under the heating zones 207 on which is (are) placed (s) container (s) 212 (see Figure 12).
- burners additional or with a displacement in the direction of the depth of the stove, that is to say perpendicular to the lines K and L.
- Burner 209a can therefore be move laterally along line L to heat one of the two containers 212 from below.
- each heating zone can be heated by two separate means of producing heat (one powerful and the other weak) arranged one below the other or one next to the other on means respective displacement. So it will be possible to heat the same container placed on a heating zone using a first means of heat production (cooking function), then, without moving the container its heating zone, to place the first means of producing heat at away from said heating zone and move the second means of production of heat under it (simmer function).
- a first means of heat production cooking function
- simmer function the second means of production of heat under it
- the heat generating means of Figures 1 to 5 can be different from a gas mixture burner.
- a solution proposed and illustrated in Figure 13 plans to use a resistor electric 52 supplied with electric energy by a cable 53 passing through the support 30.
- the heat is mainly produced by radiation (especially infrared), and the use of the plate metallic 21 is not essential for the "broiler" function.
- Use of an electrical resistance as a means of producing heat can also apply to Figures 6 to 10, in which case the blade (s) is (are) replaced by one or more resistors producing in particular radiant heat.
