Description

Field of the Invention The present invention relates generally to cooking systems and appliances, such as stove covers, braziers, heaters, grills, stoves or the like, and more specifically to conventional burners with or without bridges to provide a variety of heating configurations according to the needs of the operator of stove covers, brazier, heater, grill, stove or similar.
Description of the Prior Art Covers of stoves, braziers, heaters, grills or stoves that include one or more burners in a same axis are known in the prior art. It is common for a main burner to have a maximum thermal capacity of between about 4,220 kilojoules (4,000 BTU) to 10,600 kilojoules (10,000 BTU) per hour at its highest position. The minimum thermal capacity of a burner can be reduced to approximately 633 kilojoules (600 BTU) per hour without extinguishing the flame. It is logical that the diameter of the ring of the flame determines the heat output coefficient of the burner.
A higher output coefficient can be solved by the multiplicity of burners, or by orbital burners, such as star burners or concentric rings, which have several heat outputs in the same burner. Examples of the above exist in the prior art. U.S. Patent No. 5,842,849 discloses a gas burner which includes a base member, in which a plurality of nozzles are disposed and a disk is mounted to the base member with a plurality of gas management pipes connected between the disk and the base member. A central head member and a plurality of cameras are respectively mounted to the disk and communicate with the gas management pipes respectively. Each of the chambers and the central head member have a plurality of openings defined in themselves. Mexican patent No. 191876, discloses that by designing an oval-shaped burner, and through the design of slides, a space to burn larger than the normal space of a burner can be burned, providing greater capacity calorific (BTU's). U.S. Patent No. 6,132,205 incorporates a multi-ring burner assembly that uses at least two flame rings to evenly heat the food, and a third flame in conjunction with the first two flames, to cook the food. U.S. Patent No. 6,325,619 discloses a gas burner with multiple gas rings, comprising a burner body mountable below an upper plate, with a cut section, of an apparatus, and incorporating a first gas injector directed upwards, and a second gas injector followed by a horizontal Venturi tubular opening, towards a vertical well; an external burner head sitting above the plate in the section cut and spaced a distance above the plate and provided with an annular chamber open above the well and having one or two rows of flame holes; an internal burner head formed to have a radial divergence co-axially supplied by the first injector through the recess located in the central head, ports being provided in the head so that the primary air and secondary air needed to operate the multiple burner come from the top of the top plate of the appliance. Another way of supplying a heat greater than that of a burner is described in U.S. Patent No. 6,322,460, where a gas burner assembly particularly for incorporating cooking tops in an oven, having at least two feeding nozzles to form the mixture corresponding gas and air in two separate mixing chambers, provided with flame ports, where said flame ports can be positioned at two different levels. The burner assembly is selectively operable to provide a full range of cooking intensity. The North American patent No. 6, 435,173 discloses a combined burner and grill structure for use in connection with a stove, which includes one or more burner elements. Each burner element has one or more fuel inlets, one or more fuel outlets disposed on one or more side surfaces, and a top surface. A flat horizontal support for a cooking device is made of an upper surface for each burner element. A gas stove may include one or more of this combination of burner and grate structure. Another patent describing ring burners is US Patent No. 7,001,176, which discloses a burner for stoves, specifically for gas stoves, comprising at least two gas crowns, of which the central and at least one circumferential contain a mixing chamber with a Venturi effect, ducts for primary air inlet and radial ducts to feed the gas and primary air to said circumferential crown, comprising a body, a head and a separation element, which breaks the internal space to ducts for the entry of primary air and ducts for the distribution of the mixture of gas and primary air. Finally, US patent application No. 10 / 967,537 with publication number US 2005/0142511 discloses another way of giving a burner greater heat or thermal capacity. Said publication discloses a multiple gas burner assembly, which has two burners spaced by a bridge burner. An axis extending through the first and the third burner intersects the perimeter of the second bridge burner. The second burner provides a means for providing a substantially continuous perimeter of flame and a continuous heating intermediary for the first and third burners when the three burners are ignited. This publication is the closest prior art found. However, one of the differences between said publication and the present invention is that the distance between the main burner, the secondary burner and the satellite burner has a distance such that it allows the satellite burner to be ignited through the main burner, avoiding such burner. so that the flames of both burners have interference, which causes a bad appearance in the flame and higher production of carbon monoxide. In the figure 12 of said application a figure similar to that of the present invention is disclosed. However, it is apparent from the description of the invention, specifically on page 4, paragraphs 45 and 46, that the invention in this embodiment was not carried out. It is noted that the intermediate burner in the modalities of figures 10 to 13 of the application in question, do not have form of appropriate ignition, nor have thus, way to burn adequate.
Brief Description of the Invention One of the problems found in the covers of stoves, braziers, heaters, grills or hotplates, is that they have predetermined fixed areas of cooking by means of fixed burners, so that the user selects between said predetermined fixed areas. which burner you will be using. Another problem found in the covers of stoves, braziers, heaters, grills or hotplates, is that these predetermined fixed areas of cooking do not provide enough thermal capacity to heat or cook evenly to a casserole, comal, or other type of utensil for cooking, that has a larger dimension to the burner area of the burner, so you have to be rotating and turning to the pan, comal or utensil to cook or heat the contents. Another problem found in the covers of stoves, braziers, heaters, grills or hotplates, is that there are no burners that have a cooperation between them, allowing the user to select the burners to be used, and the number of burners to be used. Therefore, an object of the present invention is to provide an assembly of burners that includes at least two different burners on the same axis, for the best cooking and heating of the user's food. Another object of the present invention is to provide sufficient thermal capacity to heat or cook evenly the contents of a casserole, comal or the like having a larger dimension than a fixed cooking area. Still another object of the present invention is to provide burners that have a cooperation with each other, allowing the user to select the burners to be used, and the number of burners to be used. Another object of the invention is that there is a predetermined distance between a main burner and a secondary burner according to a third burner, in order that the flames of the burners do not have interference.
Another object of the present invention is to provide a stove cover or grill with a multiplicity of burners, for the user to select the burner (s) that it requires to use. Another object of the present invention is to provide burners that have cooperation with each other, and that said burners are easy to produce, assemble, clean and maintain. Another object of the present invention is to realize a design of slides, which can be used appropriately with the aforementioned burners. Finally, another object of the present invention is to provide covers for stoves, braziers, heaters, grills, stoves, or the like, with the burner of the present invention.

Detailed Description of the Invention Users of stove covers, braziers, heaters, grills, stoves, or the like, require that the stove cover, grate, etc. its burners have such a geometry and are arranged in such a way that they allow the user to have great flexibility to heat their utensils, which vary in size and shape, not only being round, but also with a square, rectangular, hemispherical base ( wok's), irregular, star-shaped, etc. Added to this, the problem is complicated if we consider the different measures of the cooking utensils and the different calorific capacities that it is required to transmit from a burner (or set of these) to a cooking utensil, depending on the dish, ingredients, recipe, or other variables of culinary aspect.
The present invention aims to provide a stove cover, grills etc., burners that can provide a wide range of heat capacities, as well as a better distribution of burners on the deck that accommodate a variety of tool geometries. cooked First Mode of the Invention Figure 1 shows an isometric top view of the satellite burner 2 of the present inventionsaid burner has a semi-rectangular shape, with longer lengths of port zones 30 standing out on its sides. On its perpendicular sides, the satellite burner 2 has a neck 14 or arc segment, to cooperate at its ends with main burners 1 , which preferably have a round geometry. As seen in Figure 3a, a mixing tube 10 or Venturi that allows the fuel gas mixture, coming from flow regulating valves 15, to be directed towards a nozzle 16, which reduces the pressure and grants a flow velocity determined. The mixing tube 10 embraces the nozzle 16, by means of a throat 19, which can be above said nozzle 16, so that the flow leaving the nozzle 16 is introduced by the mixing tube 10, generating a Venturi effect, dragging the surrounding air, introduced by windows 18. The mixing tube 10 consists of a regulating ring (not shown), which restricts the passage of air into the mixing tube 10, to modify the ratio of the combustible air of the mixture. Another embodiment of the mixing tube 10 is shown in Figure 3b, which can be used with the burner or set of burners of the present invention, such as a conical short tube inside, which does not embrace the nozzle 16, but between said nozzle 16 and mixing tube 10 there is a certain distance which allows air intake by venturi effect, while the air is drawn or introduced by the widest part of the conical mixing tube 10 thanks to the speed printed by the nozzle 16 to the fuel fluid; the fluid already mixed with air and fuel is guided through the internal body of the mixing tube 10 until it reaches the body of the burner 2, which consists of an internal chamber 7, which serves to evenly distribute the fuel-air mixture. The chamber 7 consists of an internal table 6, which reduces the space of the chamber, to standardize and speed the flow of the fuel-air mixture. Therefore, the ports in general of the burner, which will be addressed in detail later, will have approximately the same fluid velocity so that the flame darts are similar. Figure 2 shows an isometric view of the bottom view of the burner 2 of the embodiment in question, showing the support ingots on which the body of the satellite burner 2 rests. The assembly between the mixing tube 10 and the body of the satellite burner 2, which can be subjected by any type of mechanical fixation, such as: dimensional interference, fastening, riveting, by means of some binder, etc. Figure 4 illustrates an isometric view of a possible configuration of burners, specifically three burners (1, 2, 1 ') in line where in the center is the satellite burner 2 or secondary and at the ends to two main burners 1, 1 ' This configuration allows to obtain a larger heating area, along an axis, allowing to heat larger utensils, such as a tamales pot, tortilla griddle, etc., which require a high uniform heat quantity throughout of an axis, so that the comal has a greater surface area of heating, heating a greater quantity of tortillas, tamales or other foods. You can also heat three pans or a large pot and a pan at the same time. HE You can appreciate that a large range of kitchenware combinations, which may require different heating capacities can be heated with this combination. The configuration or arrangement allows the satellite burner 2 to interact with at least one main burner 1 or 1 ', since, in a preferential circumstance, a main burner 1 or 1' and the satellite burner 2 are connected to a control burner valve. flow 15 having two fuel outlets towards each burner 1 or 1 'and 2 respectively. Figure 5 illustrates the rotation angle of the knob vs. the fuel flow emitted by valve 15 (in heat capacity, namely that the ratio is somewhat linear, at higher heat capacity greater fuel flow is required). The valve 15 controls the flame of the main burner 1, so that when the knob is in the closed position at zero degrees of rotation, the valve 15 does not deliver any supply of fuel fluid to the burners. By turning the knob approximately ninety degrees, the valve 15 delivers maximum fuel flow to the main burner 1. Continuing with the rotation in the same direction, at approximately one hundred thirty degrees of rotation, the flow of fuel given by the valve 15 to the burner Main 1 is the minimum.
Continuing with the rotation in the same direction, approximately two hundred degrees of rotation, the valve 15 grants a maximum flow of fuel to both burners 1 and 2, igniting the satellite burner 2 through flare transfer ports 36, located in the corners closest to the main burner 1. When igniting the flap transfer slides 36, they transport the flame to the rest of the slides 31 and 32, in the area of ports 30 of the satellite burner 2. Continuing with the rotation in the same direction of the knob, reaching the limit of rotation of the valve 15, at approximately 270 degrees of rotation, the valve 15 allows a minimum flow of fuel to the burners 1 and 2. Another mode of operation of the present embodiment is presented at provide the satellite burner 2 with a pair of spark plugs 20, a spark plug 20 for each zone of ports 30. Additionally, an independent valve 15 is needed for each burner, making it unnecessary to use transport slides 36. Ideally, it is preferred that in this mode of operation there is a valve knob 15 for better operation. The proposed geometry should not be understood as limiting or constraining the invention in any of its modalities to this particular port configuration, since the invention is designed to operate with an area of portals determined from five square millimeters to seven square millimeters for the main portals 31, from three square millimeters to six square millimeters for the secondary portals 32, and from one square millimeter to three square millimeters for the flame transfer portals 36 Therefore, the slides can be round, square or have any geometry having a porta area limited to the aforementioned, and a separation between them, granting a finite and calculable number, starting from the periphery of the portals area 30 in the satellite burner 2, in which case, the total port area ranges from one square centimeter to three square centimeters. The mass flow of fuel gas output mixed with primary air, is linked to the portal area, regulating the passage of said fuel flow and mixed primary air. The heat capacity of a burner is a function, among others, of the area of ports, as well as the performance of the burners, since when crossing a mass flow of gas through a certain area, its speed is modified and therefore the stability of the flame is affected by the size of the portal area. The heat capacity, in conjunction with the portal area, defines the charge of the portal, which is the amount of kJ / Hr emitted by the burner per unit area (kJ / Hr * mm2). Next, the geometry of the slides is described. Figure 6 shows a front view of the satellite burner 2, showing the geometry of the slides used. This geometry consists of three types of slides: a main portal 31, which gives a long and stable dart, a secondary portal 32, which complements the primary carrier 31, and provides flame transport between primary or main ports 31, and a flame transfer port 36 located at the corners of the port area 30, at the end closest to the burner main 1, which gives a long flame dart that is ignited when the burners 1 and 2 have maximum fuel flow, the function of the transfer port 36 being to obtain flame from the main burner 1 and transmit it along the zones of ports 30 of the satellite burner 2. Figure 6 also shows the area of ports 30 of the satellite burner 2, where it can be seen that the main ports 31 have a semi-rectangular shape, where their base is less than their height. The corners where the horizontal base is joined with the vertical sides, which determine its height, are rounded. The sides are not completely perpendicular to the base, but approximately have one to three degrees of inclination.
The semi-rectangle closes when the cover 9 of the satellite burner 2 is placed, where the construction ratio of the semi-rectangle is that the height of the sides should be 15% to 40% larger than the size of the base. In figure 6 together with figure 6a and 6b it is observed that the geometry of the secondary slides 32, which have a smaller area than the primary slides 31, also resemble a rectangle, with the exception that compared to the main slides 31, the base is longer than the sides, thus having a height ratio of the sides of 5% to 20% of the base dimension. Like the primary portals 31, the open side of the rectangle is closed when placing the cover 9 of the satellite burner 2. The distance between main ports must be between 4mm and 8mm, where on the upper face of this separation the secondary slides are located 32, as shown in Figures 6, 6 a and 6b. The transport slides 36 are located at the end of the port area 30 closest to the main burner 1. These ports have a peculiar construction, since they must emit a long flare dart that can be ignited with some flame dart main burner 1, located in the two corners closest to the main burner 1. Figure 6a allows to appreciate that the transport carrier 36 has a valley of about 0.05mm to 1.5mm lower than the part highest of the distance between slides, dimension denominated as H highlighted in figure 6a with a horizontal fan from 70 ° to 110 ° from the main portal 31 closest to the center coinciding with the arc formed at the end of the zone of slides 30 and the adjacent end of the front side 14 of the satellite burner 2. The distance between the side side 14 of the satellite burner 2 and the nearest part of the main burner 1 is represented by the dimension Z, which is calculated partially with respect to to the length of the flame darts of the main burner 1 so that there is no interference or objects that hinder the path of the dart, in order to have a combustion and correct formation of the flame dart. Therefore, the Z dimension must range between seventeen to thirty-two millimeters. For its part, the dart emitted by the flame transfer port 36 has an approximate dimension of four to nine millimeters. A flare dart emitted by the main holder 31 of a main burner 1 measures about fourteen to eighteen millimeters, so the Z dimension apart from the flame length criterion and configuration for the flame transfer, also obeys a ratio of separation between burners 1 and 2 that allows them to properly develop their respective darts and grant enough secondary air to these to obtain a correct combustion. As can be seen in figure 7, the satellite burner 2 has a limited length according to the radius R of the main burner 1. The maximum distance of the length of the satellite burner 2 is limited, in this mode, by the radius R of the main burner 1 and the radius Rx of the main opposite burner 1 and a predetermined distance Y so that the operation of the three burners 1, 2, 1 'is appropriate when they are lit at the same time. The distance Y prevents the flames of the main burner 1 and the satellite burner 2 from interfering with each other, even when both the main burners 1 and 1 'and the satellite burner 2 are switched on. If the flames cross, it causes a bad appearance of the flame and a greater production of carbon monoxide, and therefore poor efficiency and combustion. The distance Y in any case should not be less than fifteen millimeters, however, the greater this distance there will be more secondary air around the flame darts. The width of the satellite burner 2, is equal to the diameter of the main burner 1, being equal to twice the size of the radius R. The arc segments 14 of the satellite burner 2, do not have ports, except the transfer port Flame 36 in the corner. The above in order to avoid contact between the flames of the main burner 1 and the secondary burner 2. Once the cover 9 of the satellite burner 2 is put, the arc segments 14 of the satellite burner 2 are sealed, so it is not allowed gas outlet in satellite burner 2, except for ports 31, 32 and 36.
Second Modality of the Invention Figure 8 shows a second embodiment of the burner of the present invention. The main burner 1 has modified its shape to a kind of horseshoe. On the periphery of this horseshoe is the area of portas 30. Once the circular shape of the main burner 1 has been changed to this new horseshoe shape, we will call this burner as the main burner horseshoe 5. When merging the horseshoe main burner 5 with the secondary burner 2, a body 37 with a semi-rectangular shape is obtained in the front of the two burners 5, 2, and with the ends lateral of semicircular form. The horseshoe main burner 5 and the satellite burner 2 are fused in the same body 37, providing advantages when both burners 5, 2 are assembled, produced, maintained and installed.
Descriptive but not limiting can be considered a design of slides as described in the previous modality. It can be observed in FIG. 8 that the arc segment 14 of the satellite burner 2 is without ports, so that no flame is emitted in said zone. Between the satellite burner 2 and the horseshoe main burner 5, a separation 39 is located, so that the gas emitted by the double fuel outlet valve 15 connected to both burners 5, 2, does not pass between the burners 5, 2, managing to light the horseshoe main burner 5 first and only use this heating zone. Additionally, if the knob of the dual fuel outlet regulating valve 15 is still rotated, the satellite burner 2 can also be ignited. In this embodiment, a tertiary carrier 33, previously described as a flame transfer carrier, is provided by a groove starting from an inner point and proceeding towards an outer point and occupying the entire portion of the separation 39. The groove ends on the same spacing 39, since to reach the side of the satellite burner 2, the combustible fluid emitted by the respective valve 15 could pass from the primary burner 1 to the satellite burner 2 or vice versa, igniting both burners at the same time, which is an undesired effect. Therefore, the cut of the slot is close to the separation 39. The slots in their respective sides, serve as tertiary ports 33, where said tertiary carrier 33 transports the flame between the main burner horseshoe 5 and the satellite burner 2. As in other embodiments, the flame emitted by the tertiary carrier 33, given its configuration, it will light the main port 31 closer to the tertiary port 33, the flame will then turn on the secondary port 32 closest to the tertiary port 33, the sequence is repeated until all the primary 31 and secondary portals, 32 are located. lit. The ignition of the second embodiment is similar to the satellite burner 2 described in the first section, since it contains a double flow valve 15 and only one spark plug 20, as can be seen from figure 9. However, it is possible that the burner may have independent flow regulating valves, as mentioned above for the first embodiment of the invention. In figure 9 which is an isometric lower view of the body 37 formed by the fusion of a horseshoe main burner 5 and a satellite 2, it can be seen that said burners 1 and 2 each have their feeding tube 10. The main burner horseshoe 5 keeps the spark plug 20 for ignition. Other characteristics that both have Burners 1 and 2 when merged in the body 37, are the burner chambers 7 and tables 6, as seen in Figure 8, with both burners sharing a lid 13, as illustrated in Figure 10. In Figure 10 , another mode of operation of the burners fused in the body 37 is observed, by including in the stove cover a round main burner 1 where, as discussed in the first embodiment, the dimension Y must maintain its relationship with the characteristics described for the first embodiment of the invention, such as that the dimension should not be less than fifteen millimeters, and that the greater the distance from the main burner 1 of the body 37 of the burners burned will be better, for reasons of secondary air supply as well as by dart interference. Figure 10a in turn shows a front view of the main burner arrangement 1 with the body 37 of the burners 5 and 2 fused, where both the main burner 1, and the body 37 of the burners 5 and 2 fused, each keep a spark plug 20, so that it is not necessary to store the dimension Z discussed for the first embodiment of the invention, since the flame transfer ports 36 are not necessary. Similarly, in figure 10a, it can be seen that the mixing tubes 10 feeding the three burner chambers 7 are independent in each case.
Third Modality of the Invention With the fusion of both burners in a single body 37, a main burner 1 and a satellite burner 2 are once again united in a single body, giving advantages of: manufacturing, assembly, maintenance, fewer parts to handle . The main burner 1 and the satellite burner 2 or secondary burner are fitted on a single base 38, where the main burner 1 is called the circumscribed main burner 21. As n in FIGS. 11 and 11, said circumscribed main burner 21 retains its zone of ports 30, spark plug 20, table 6, camera 7 and cover 11, with the peculiarity of being connected to satellite burner 2 through a base 38, allowing both burners 21 and 2 contained in a single piece. For its part, the secondary burner 2 also retains its area of slides 30, table 6, chamber 7, lid 12 and a pair of flame transfer slides 36 at its ends in the area of slots 30 closest to the circumscribed burner 21, such and as they were described for the first embodiment of the invention. This description is held here as if the letter were read. Like the first modality the distance Z that refers to the distance between the flame transfer port 36 of the satellite burner 2 and the main carrier 31 closest to the circumscribed burner 21, it must keep the same characteristics specified, such as said distance Z which refers to the distance between the circumscribed burner 21 and the satellite burner 2, and is in function length of the flare dart of the circumscribed burner 21 and the length of the flare dart emitted by the flame transfer port 36 of the satellite burner 2, so that there is no interference with any object or the wall of the secondary burner, considerations to be taken account when determining the separation between circumscribed burner 21 and secondary burner 2 fitted to the base 38. These considerations are made by having both burners at the same horizontal level, that is, that the port zones 30 of both burners 21 and 2, are collinear as illustrated in figure 12, on which an aa axis has been arranged for better reference. Another embodiment of the present invention occurs when the areas of ports 30 of both burners 21, 2 are not collinear, as seen in Figure 12a, where it is observed that the circumscribed burner 21 has a greater height than the satellite burner 2. configuration obeys to an optimization of the distance between burners, as well as to a better accommodation of these in the space. Having a distance To lower the satellite burner 2 of the circumscribed main burner 21, obstructions of the flame darts emitted by the ports of the main burner 21 are avoided. Additionally, the raised position helps to improve the combustion, since the flame darts reach from better secondary air, also improving the efficiency and heat transfer, since the main circumscribed burner 21 is closer to the cooking utensils. Figure 12a s a dotted box that is amplified in Figure 12b, where you can see in detail the difference in height A highlighted by the axes cc and bb whose vertical difference represents the dimension A. Said axes cc and bb in relation to geometries of slides, are constructed taking as reference a point of reference of the slides, as its axis of symmetry, valley, peak, etc. The distance A obeys to the height of the flare dart that by criteria of efficiency and combustion, it is preferable to find the uneven darts, where A is between three to five millimeters preferably. Another embodiment as seen in Figure 13a, is presented by including a window 22 in the base 38 in the area between burners 21 and 2, the window 22 is accompanied by a certain separation between the base 38 of the burners 21 and 2 Y the stove or kitchen cover, allowing the flow between the lower part of the base 38 and the stove or kitchen cover on which the burners 21 and 2 are mounted., creating an air flow that is exploited by the circumscribed primary burner 21 flame flares emitted in the area between the satellite burner 2 and the circumscribed primary burner 21 itself, which helps supply secondary air to the flame darts. Figure 13b shows an isometric view of the third embodiment of the present invention, with the window 22, which helps to supply secondary air to the slides in this zone of the circumscribed main burner 21. Said main burner 1 shows the lid 11 that it is supported by the port area 30 and closes the burner chamber 7. The figure also shows that the satellite burner 2 shows the cover 12 that closes the chamber 7 of the burner which is also supported by the area of ports 30 and sealing the arc segments 14 of the satellite burner 2. It should be mentioned that the burners 21 and 2 may each be fed by an independent flow regulating valve.
