These holes could cause inconveniences in a cooking apparatus encased in a gas range top.
- burners have been also used with three concentric flames or crowns obtained by two rings in a single piece, but with two separate gas deliveries on the inner ring and the outer ring, separately controlled by two different gastaps or even a single gastap which controls the gas feeding to the outer ring only from a certain level of opening of the delivery onwards, while for reduced supplies the gas flows only from one of the rings or crowns, usually from the innermost one.

- the object of this invention is to provide an arrangement comprising a burner providing three concentric flames obtained by two members only, to be encased in a worktop of a gas range top, which is free from the aforesaid faults and drawbacks, since it may be fed by a single gas delivery with a single control tap and therefore has a single spark-plug and a single safety thermocouple.

Description
- This invention concerns an arrangement comprising an improved gas cooker burner with three concentric flames, and precisely, of the type with flame dividing member in a single piece.
- It is known that in hobs or gas cooker at least one of the burners, intended to be used with the cooking containers of greater diameter, is preferably provided with multiple concentric flames, typically three, to improve the distribution of heat on the bottom of the container itself and thereby have a greater cooking efficiency. This can be achieved with burners and relative flame dividers dismountable into several pieces, but presenting in such a case drawbacks caused by the poor maintenance practicality and the difficulty in obtaining a satisfying level of cleanliness of the pieces themselves.
- For example GB-A-2 233 444 discloses a cooker gas burner composed of at least a burner core, a cylinder with upper hollow chamber and lower hollow chamber, with a dripping plate due to the primary air being untaken from the space underneath the top-plate, what requires air intake holes formed on the top plate on which the burner is mounted. These holes could cause inconveniences in a cooking apparatus encased in a gas range top.
- To overcome these inconveniences burners have been also used with three concentric flames or crowns obtained by two rings in a single piece, but with two separate gas deliveries on the inner ring and the outer ring, separately controlled by two different gastaps or even a single gastap which controls the gas feeding to the outer ring only from a certain level of opening of the delivery onwards, while for reduced supplies the gas flows only from one of the rings or crowns, usually from the innermost one. Actually it proves to be particularly difficult to achieve an even distribution of the gas in the different members which give rise to the concentric flames, so as to have both an exact balancing of the pressures and an adequate flow of secondary air by the different flame areas, while assuring the propagation and preservation of the flame itself, without the presence of frequent flame separation phenomena.
- In any case accomplishing a burner of the last indicated type, manufactured according to the prior art, would have required the adoption of at least two spark-plugs and two safety thermocouples, even in case of single delivery, supposing that such a burner would have been able to work.
- Consequently the object of this invention is to provide an arrangement comprising a burner providing three concentric flames obtained by two members only, to be encased in a worktop of a gas range top, which is free from the aforesaid faults and drawbacks, since it may be fed by a single gas delivery with a single control tap and therefore has a single spark-plug and a single safety thermocouple. In this way the flames spread immediately from the ignition point on the outer crown all the way to the innermost one and there remain, with no flame separation, even for reduced gas delivery, controlled by a single gastap quite similar to the conventional ones for single flame burners.
- This is achieved through a burner comprising a basic distributing body, connected to the outlet of a gas delivery tube and a flame dividing member to be placed on said distributing body, wherein said body has three radial gas passage areas and three intermediate secondary air inlet areas, and said flame divider is formed by two concentric rings connected by three radial members which form the respective cover of the above-mentioned gas passages, with intermediate through apertures for the secondary air, the inner ring having on its periphery two staggered rows of holes, one above the other, as well as staggered rows of holes on the confronting surface formed by the inner periphery of the outer ring, whose outer periphery has other two series of holes, also one above the other and there being provided a single spark-plug and a safety thermocouple level with the upper series of holes, wherein said distributing body is mounted on a raised area of the worktop surrounding said burner, whereby the latter remains raised some millimeters from said worktop making easier the adduction of the secondary air both to said outer holes and, through said internal passages, to the inner ones.
- These and other objects, advantages and characteristics of the improved burner according to this invention will appear more clearly from the following detailed description of its preferred embodiment, reported as non-limiting example, referring to the annexed drawings wherein:
- Fig. 1 shows an exploded view of the burner according to the invention; and
- Fig. 2 shows a partial radial sectional view of the burner of fig. 1 assembled for its operation.
- With reference to the drawings the burner according to this invention, fed by the
outlet 10a of agas delivery tube 10 of conventional type, is formed by a body 1 of the real burner upon which a flame dividing member 2 is placed, as it generally occurs in the known single flame burners. The body of the burner 1 serves the purpose, particularly important in this case, of properly distributing the gas, or rather the mixture of gas and primary air fed by thetube 10, to the different flames of the member 2. In order to do this the body 1 has radial passages 3 communicating with a central hole 5 coaxial with 10a, and separated one from the other by the raised walls 7 defining the vertical passages 9, therefore perpendicular to the plane of the body 1, for the entry of the secondary air by the central flames. The passages 3, as shown in Fig. 1, are three, as well as the secondary air inlet areas 9. - The flame dividing member 2, in a single piece according to the invention, substantially includes an
outer ring 4 and aninner disc 6. The three flames rise from proper holes on the outer and inner periphery of thering 4, as well as on the outer periphery of thedisc 6. Theouter ring 4 and theinner disc 6 are connected by radial connecting members 8, coinciding in number and position with said passages 3 of which they define the upper wall or closing cover. On the outer edge of the circular plate forming the burner body 1 there are also two holes 11a and 13a for the positioning of a spark-plug 11 and asafety thermocouple 13 respectively, as well as for the passage of the relative connections to the respective controls, in such a position that the active parts of bothelements 11 and 13 are near the outer periphery ofsaid ring 4 of the flame divider 2. - With particular reference to fig.2, the holes on the flame divider 2, through which the gas comes out and by which the flame is formed, are shown in greater detail. The holes on the
inner crown 6 are indicated by 12 and those on theouter ring 4 by 14 and 16, on the inner and outer side respectively. All the holes are preferably oriented upwards and particularly those indicated by 12 and 14, on confronting surfaces, are directed one against the other so as to produce converging gas flows, thus meeting in an intermediate position, substantially along a circumference having its diameter included between that of thecentral crown 6 and the inner diameter of thering 4. - According to a preferred embodiment of this invention all the
holes - It should be noted that the gas flow is directed radially outwards, as already said before, while the flame spreads inwards starting from the external spark-plug 11. It should also be noted that by the
inner holes 12 the gas has a higher pressure, consequently their diameter will be smaller than that of theholes 14 and even smaller compared to theouter holes 16. Moreover to avoid the separation of the flame, which could take place anyway due to this higher pressure, above saidholes 12, along the periphery of theinner disc 6, a projectingledge 18 is provided, capable of reducing this pressure and the occurrence of this phenomenon. - Always with reference to the figures, it clearly appears that the
holes 14 are provided on limited areas only of the inner periphery of thering 4, and precisely they are missing by the radial connections 8, that is by the gas passages 3. Therefore in the case shown and above illustrated there are threehole areas 14 by the secondary air inlets 9. - As far as the outer flame is concerned the
relative holes 16, of greater diameter, are only slightly inclined upwards, while there is a second series of holes 16a below, of smaller diameter, wherein each hole 16a is preferably vertically aligned with anupper hole 16 for which it acts as pilot light, as besides is known in prior art. The secondary air for the outer flame reaches theholes 16 and 16a with no particular problems, but this is made easier by a preferred shape of theworktop 20, which forms a raisedarea 21 on which the burner body 1 is mounted, so that between the latter and the surrounding top remains a space of some millimeters, suitable to make the passage of the secondary air easier, especially in the inner part through the ducts 9. - From what comes before it clearly appears that with a
single delivery 10, adjustable through a single control tap (not shown), the gas flow is adjusted from a minimum to a maximum always preserving the three concentric flames. The ignition is single as well by means of a single spark-plug 11 which first of all causes the ignition of the gas that comes out of theholes 16 of theouter ring 4 and then the gas which is pushed outwards from theinner holes 12, which in turn spreads the flame to the as flow, converging with it, coming from thecentral holes 14. Obviously thethermocouple 13 is single too and controlled by the existence of the outer flame, which presupposes the presence of the two innermost flame crowns too.
