Description

IMPROVED BURNER BURNER I > AR? ECONOMIC COOKING EQUIPMENT BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a burner die cut for cooking equipment using L.P. Die-cut burners are normally used as surface units in industrial domestic type kitchen equipment.

The burner of the present invention is of economic type because it is manufactured with by-products of other white line manufacturing processes that use rolled steel with low thicknesses.

Conventional die-cut burners are usually fopnados by pieces of sheet die-cut and assembled so that the combustion chamber is permanently formed that is, its assembly is generated by a die.

However, the main problem with these burners is that they usually have a low thermal capacity, which represents a greater gas expense when carrying out the cooking operation. Another problem with this type of burners is the fact of presenting difficulty when regulating the entry of primary air into the combustion chamber, this is usually due to the fact that the regulation means are located below the cover of the equipment. of cooked. It is therefore an object of the invention to provide an improved die-cut burner that allows to increase the thermal capacity by 40% compared to the capacity that conventional burners handle, thereby reducing the cooking times of the food. One of the objects of the invention is to provide a compact burner that has a total integration of its parts necessary for its complete operation, that is, the tube and the air regulation ring can be manipulated by extracting the burner from the top of the cover, as these two elements are included in the burner assembly.

DESCRIPTION OF THE INVENTION The invention is described below according to the drawings of Figs. 1 to 5 wherein.

Figure 1 represents an isometric cascade view of coupling Figure 2 shows a front view of the burner assembly of fig. 1.

Figure 3 is a view in a longitudinal section of the burner of fig. 2. Figure 4 is an isometric view of the burner showing its assembly arrangement in the cooking equipment The iguia 5, cs a front view of the burner assembled to the cooking equipment The invention relates to a top burner for domestic gas stoves "LI", with ignition of the type whose main characteristic is that the air regulating tube is included, that is to say that together with the burner is a single compact unit. that is obtained by having the air regulator tube included in the burner provides faster and easier access, since currently the upper cover has to be lifted to regulate the entry of primary air to the burner, this involves removing burners, grills, removing or lifting the cover and then regulating the air.With the design of the present invention, it is no longer required to do this operation, since only the burner is raised and adjusted.Another new feature is the large thermal capacity in which it operates. the burner which is 7000 BTU / HR, since at present no economic burner has it, by means of the design of the invention a reduction in the time is obtained or cooking of food, as well as an effect of the flame pleasing to the eye.

According to figures 1 and 2, the burner 9 of circular type is constituted by an air regulating tube 10, a ring 11 for the air regulating tube, a combustion chamber 24 integrated by a burner base 12, a burner body 13, and a burner cap 14.

"The air regulating tube 10 is a section of tube that in its lower part has four punched windows 26 arranged equidistantly for the primary air inlet that is supplied to the combustion chamber of the burner 24. The ring 11 which is coupled concentrically to the air regulation tube is a piece of tubular section with a longitudinal opening for closing control, it is made of sheet and rolled steel for its tubular configuration, and it is adjustable by precision in the air regulation tube 10, and that depending on the geographical region where the burner is used, said ring covers a section of the window of the air regulation tube, that is, higher above sea level, the greater amount of air required by the burner.

The combustion chamber of the burner 24 is designed in order to have the volume of gas necessary to supply fuel to the slides, as well as to avoid an explosion inside the burner when it is turned off, this because when closing the valve it is tipped with the supply of gas, and is gradually disappearing, due to the difference in pressure that exists outside and in the interior, where the greatest pressure is that of the outside and the infepor is that of the interior, the gas is stored for a moment in the camera and causes a small explosion inside the burner.

The slides, arranged in the body, have a uniofopne distribution around them, with a predetermined number of them which is a function of the thermal capacity of each of them, as well as the load that is required for each port. The object of having two different diameters and at different heights, is for the flame to breathe, that is to say, so that it has the necessary supply of secondary air, which allows correct combustion, and on the contrary if the flames are joined more You would get secondary air will be contaminated, as you would not have enough space to be able to get clean air and carry out combustion. Said chamber is formed by three pieces of laminated steel which are: the base 12 which is a die-cut piece with a concentric orifice in the central part, where the air regulating tube 10 is coupled; the body 13 of cylindrical type with a lower section greater than the upper one, is also a die-cut piece that has in its outline a plurality of ports 27 disposed cquidistantly, said gas outlet ports are manufactured by means of punches that give the shape of a port circular 27 intercalated with a rectangular port with radial ends which allows a secondary aeration of the flames representing a greater oxygenation for the flames of the burner, that is to allow a complete combustion of the gas, the body 13 is coupled in turn to the base 12 by means of a bend assembly 25 that does not allow leaks in the lower part of the combustion chamber, the cover 14 is a circular rotary section punched out of rolled steel, which is engaged for assembly in the upper part of the body 13 by a fold assembly. In all the assemblies the seal is ensured by applying an enamel bath on the burner.

Operation of the burner "A line of LP gas supplies the fuel to the valve tube 21, with a constant flow and pressure to all the burners, the valve 23 is operated by an axial turn in a counter-clockwise direction, which allows the passage of the gas to the feed tube 18, at the opposite end is fastened to the support 16 by nuts 17 and 22, 19, to the valve 23 and a seal 20.

The gas supplied by the feeding tube 18 is discharged in the lower part of the air regulating tube 10, the gas passing through the aeration windows 26 creates the effect called momentum; here you get the first air-gas mixture, by following its path the gas is added with oxygen that is obtained from the air around it. The gas collides in the lower part of the lid 14 of the burner which, by its torispherical shape, uniformly distributes the gas-oxygen mixture to each of the ports to be ignited on the outside of the burner and achieve complete combustion of the gas.

The burner is supported by the upper cover 15 of the gas cooker unit. the distance that must be considered between the outlet of the feeding tube 10 and the internal part of the burner cap 14 also called the burner head, is very important because a mismatch in said dimension causes problems for the uniform distribution of the mixture gas-oxygen, resulting in harmful levels of free air CO.

As mentioned earlier in regions above sea level, the primary air that is supplied by the aeration windows 26 must be larger so that the ring (11) must be displaced along the air regulating tube 10 so as not to obstruct said aeration windows 26 Having ports of two different sizes and sizes provide a greater possibility of external oxygenation (addition of secondary air) this is in case the air supplied by the aeration windows 26 (primary air) is insufficient to achieve a complete combustion of the gas supplied to the burner.

Having described the invention is considered a novelty and therefore the content is claimed in the following:
