[0001] It is the multi-burning system mountable to domestic gas cooking appliances used
in houses and provides homogeneous heating of cooker placed on it. This burning system
provides homogeneous distribution of flame by burning so as ring with three or four
levels. There are one or two inner ring burning and one and two outer ring burning
according to the burning system. The flow rate of gas is regulated by means of a gas
valve and thus the control of inner ring and outer ring are made. The burner systems
used in currently used ovens or cookers sing burning system is used. Totally three
different burnings as small, medium and large are provided on oven or cooker in three
different burner. Besides them also burners those accommodates two or three burning
systems inside them are started to be used. These burners those accommodate two types
of burning inside them are usually accommodate small and large burner inside of them
simultaneously: These burners are separated as power systems 2.5 kW, 3.6 Kw, 3.8 kW,
4.5kW and 5kW generally. But it is required to send air and gas mixture with correct
ratio to the ports of the burner by designing each of these burners separately in
order to obtain this power.
[0002] The burners those have this type one inner ring and one outer ring burning system
have been used in Far East countries for many years. But this type of burning systems
used in the Far East countries do not provide excessive control. A mixing chamber
is implemented to these types of systems today and they took their current modern
form. In case of to talk on technical space in the operation of the system requires,
one or more inlet provides air entrance and this primary air mixes with gas in a mixing
chamber this is carried to burning chambers by venturi effect. The air - gas mixture
those come out through burning ports are provided to burn by a means of ignition.
For continuity of burning secondary air drawn out of the environment during burning.
[0003] At the same in order to be able to mount such type or similar burners to cooker or
oven they need to have same mechanical connections. Since oven producer places holes
and connection points on the iron sheet placed on the iron sheet according to this.
If it is needed to give a simple example to this, the centers of the ears those are
called as ear in which thread is opened and the center of bore of bored place located
on the top iron sheet of the oven and to which this burner will be attached are same.
Therefore, burner producers keep these connection points fixed while they are making
designs. If these connection points are changed, oven producers may not use them.
PREVIOUS TECHNIC
[0004] Burners for ovens or cookers those equipped two or more gas head exist so as known
burners those have three heads one of them looks at inside and two of them looks outer
side of the cooker.
[0005] There is a patent application with patent number
GB2233444 made on 16the August 1989 in the name of Cheng-San Lee. The multi-burner is described
in the mentioned patent application such that: A groove placed vertically that supports
the burner and feeds the gag coming and the head placed on this groove that has three
crowns The crown which is placed in middle part is in the coaxial situation with before
mentioned vertical groove and in connection with it. Three linking rods those are
separated from this vertical groove are going to peripheral flame differentiation
surface at the outer side by feeding basic air and gas mixture. Here the two peripheral
crowns for outer and inner flames are placed on this flame ring.
[0006] However the above mentioned structure unfortunately is not quite convenient to use
in side supplements of gas cookers. The reason of this is the low profiles of these
burners those do not allow the use of long grooves those mix gas and air mixture.
Furthermore, peripheral flame crown oriented to inner side will have lesser flame.
Also the reason of this is the burning problem in this type of burners resulted from
interferences of crowns of which their opposite surfaces facing each other to each
other.
[0007] There is patent application with patent number
WO 2007007298 (A2) on 13th July 2006 recorded in the name of Bek Metal Enjeksiyon San. Ve Tic. Ltd. Sti.. The said patent
application is related with burners those are used in gas cookers and have multi flame
crown. A chamber cover that is developed and can be easily removed and attached is
mentioned in the said invention. The said cover is shown with figure 4 in the invention.
This chamber cover placed in the system causes cost overrun in these type products
and it may hinder the arrival of air gas mixture homogeneously in case of this cover
gets loose in the system.
[0008] Also it is asserted that there is a burner that ensures the protection of impurities
to skip in injector inlet by closing the top of the injector that provides gas entrance
and prevention of blockages those may occur by means of this. But the cover that closes
the top of the injector is not connected to the system mechanically. It is quite difficult
to prevent entrance of impurities between this kind of a cover that does not connected
mechanically and is left idle in the system. Since cleaning agents of this type of
system are composed of very small particles and liquids. As it is known liquids and
very small particles may move from the smallest emptiness that they find and they
may pass from the smallest emptiness in the system. In this sense the invention cannot
solve the problem absolutely
[0009] The solution of the technical problem explained in above can be possible with the
burner that is our invention. The above mentioned patent application does not cover
our invention although it constitutes a technical infrastructure to our invention.
Gas - air mixture does not come out from a middle point and this zone is closed. Therefore,
it s impossible any substance that enters from outside to block gas outlet and gas
exit points. Also housewives of today have difficulty in cleaning of this kind of
systems. Because the design structure of burners those have multi-burning system is
quite complex. Therefore, dismantling these burners is quite hard.
[0010] In the patent application recorded in the name of SABAF SPA (IT) on 24
th June 1997 with patent number
EP 0797048 (A1), a burner is mentioned with a central flame ring, two co-central circular crown,
basically a horizontal venturi effect chamber and bore or grooves for providing air
and gas from venturi chamber to central crown for gas cooking appliances. The said
patent said that the total vertical height of the burner is reduced relative to the
previous one. But the height of circular crown that provides small burning and located
in the middle of cylindrical head shown with figure 16 is reduced. In the said invention
the secondary air that was given from the bottom was insufficient and at the same
time a secondary air feeding is required from a second place. Therefore, the crown
at the middle part is raised a little more.
[0011] The patent application dated 23
rd January 1004 with number
WO2005080870 A1 recorded in the name of BURNER SYSTEM INTERNATIONAL(BSI) is related with a burner
head that has a peripheral crown and carries burning head that is fed by radial grooves
extended from the said central head fed by a central orifice for gas cooking appliances.
In the mentioned system wastes those come from outside to burner cup that carries
the burning head and that is shown by figure 1 may be very easy and the burning of
the system may be affected by time because of central head in the middle is fed through
an orifice.
Also the said radial grooves may become dirty in time and air-gas mixture may not
be fed in the desired efficiency within the system. Also the said central head is
located very high relative to peripheral crown and therefore, total vertical height
of burner is increased. This also causes higher cooker production of cooker producers.
Thus the invention is not an economic solution.
[0012] The solution of the technical problem explained in above can be possible with the
burner that is our invention. The above mentioned patent application does not cover
our invention although it constitutes a technical infrastructure to our invention.
This vertical height can be drawn to lower heights as per the requirement of the design
of our invention and secondary air quantity that comes through cooker and burner to
middle crown section is increased. The design of our invention allows this. Therefore,
our invention is exceeded the known state of art and contains innovation.
[0013] In the patent application in June 2001 with number
EP1297281 (A1) recorded in the name of SABAF SPA [IT] a burner is explained that covers minimum
two gas heads minimum a circular one, a mixing chamber that carries venturi effect,
grooves for incoming primary air to minimum one of the mentioned circular head, a
house, a head and the grooves for enterance of primary air that contains radial grooves
for feeding gas/primary air and a seperationdividing into grooves component for distribution
of gas/primary air. The part that separates air-gas mixture and primary air is called
by figure 4 in the said invention. This part mentioned in the invention separates
primary air and air gas mixture by connecting with screws those are mechanical connection
components or with the help of deformed pins by forging. However, in case of the mentioned
part with figure 4 is connected to system by using a connection component such as
screw, the leakages may connection points and this also may effect the efficiency
of the system negatively. The connection with screw is not an ideal solution. On the
hand in case of part deformed by forging is used the small leakages may be prevented
but in this case it is impossible to adjust defective manufacturing. This also may
open way time and cost lose in serious sense. Also a burner's that is connected to
the system in the shape of cross by the help of screws or pins deformed by forging
groves through which primary air and gas/primary air pass may be blocked in a very
short period. This groove cannot be cleaned fully since housewives cannot dismantle
this part shown with number 4 and this causes the blockage of them in the future.
[0014] In the patent application dated
9th January 1998 with patent number WO9830838 A1 recorded in the name of ROBERTSHAW CONTROLS CO [US] a burner that has surfaces more
than one however burning is realized in only one of them and provides either narrower
or broader heating surface in this way. In this application heating is provided on
a single surface and quick cooking by means of burning on many surfaces is not possible.
In the patent application in July 1994 with patent number
EP0634608 A2 recorded in the name of DEFENDI OFF MEC 10 SRL [IT] a burner having multi-pieces
that contains flame outlets from two surfaces and radial grooves that will connect
these outlets are explained. This invention is composed of five components. The production
of this burner which operates with injector holder system is difficult and costly.
[0015] The patent application dated
23rd September 1997 with patent number EP0903538 A1 recorded in the name of SABAF SPA [IT] contains a central flame crown and two peripheral
flame crowns. There is a horizontal venture chamber formed between house and flame
cover in this burner. However the said burner has many disadvantages besides its advantages.
Since the venturi effect is formed between the house and flame cover the geometric
form of the cover that will create this effect has great importance and it increase
the cost of production. This venture effect if formed by the flame cove that is produced
for this burner only and use of similar covers are not possible. Again this venture
effect is affected negatively in any deformation that will be formed in the said cover.
The open top of the injector that provides gas to the chamber in which venturi effect
is formed and during cleaning of the burner some impurities may run inside may cause
blockages.
[0016] Consequently the existence of the need for multi-burners those eliminate the disadvantages
of multi-burners in the current technology and insufficiency of available solutions
require to make a development in the related technological area.
PURPOSE OF INVENTION
[0017] The purpose of the invention is to develop a burner that uses both horizontal and
vertical venturi effect and provides homogeneous heating of saucepans and pans those
are put on ovens and cookers in houses.
[0018] The other purpose of the invention is to realize the said horizontal venturi effect
independent from the flame cover.
[0019] Another purpose of the invention is to prevent impurities to run into the inlet of
injector and to avoid from blockages those may occur by means of this.
[0020] Another purpose of the invention is easy mounting and dismantling.
[0021] Another purpose of the invention is easy cleaning of gas feeding routes because of
its easy dismantling.
[0022] Another purpose of the invention is two flame crowns those may engage to each other
and the injector holder that caries these two flame crowns can be produced by easy
casting method.
[0023] Another purpose of the invention is that the invention can be mounted without making
any changes instead of this type of burners in the known state of art.
The burner realized in order to reach the purposes of the invention is basically composed
of two flame crowns those create horizontal and vertical venturi effect when they
are mounted to each other and a injector holder that carries these two flame crowns
and provides the attachment of the burner to cooker or oven and two flame covers those
close these two flame crowns and direct flame to gas outlet ports. The structural
and characteristic specifications of the invention and all of its advantages will
be understood more clearly by means of figures those are given below and detailed

DETAILED EXPLANATION OF THE INVENTION
[0026] The invention is tried to be explained in details based upon the attached drawings.
In order to mount said invention burner (1) to a cooker; there are the injector holder
(5) that carries the injector (2), thermo coupling (11) and ignition unit (12), small
flame crown (3) and big flame crown (4) to be mounted to oven iron sheet (6), four
bores (5.2) on the periphery of injector holder skirts (5.1), two thermo coupling
slots (5.3) for the purpose of providing the attachment of security system to the
invention, an ignition unit slot (5.4) for the purpose of providing more rigid attachment
of the invention three pins (5.5) and two bores (5.6) in points close to these pins
(5.5) as shown in Figure 2. The said invention can be mounted into the oven easily
by screws (13) by means of four bores (5.2) on the periphery of the injector holder
skirts (5.1), three pins (5.5) located at the bottom of the injector holder (5) and
two bores (5.6) at close points to these pins (5.5). Four bores (5.2) on the periphery
of the injector holder skirts (5.1), three pins (5.5) located at the bottom of the
injector holder (5) and two bores (5.6) at close points to these pins (5.5) are designed
with the same distances of bore centers of the burners in the known state of art.
Due to this oven producers may use this invention without making any modification
in the designs of ovens and cookers those they use previously. However, in case of
requested, these mounting points may be brought to requested measures.
Two thermo coupling slots (5.3) for the purpose of providing the attachment of security
system to the above said invention do not exist in the known state of art.
[0027] The purpose for making these slots (5.3) as two units one of these slots is placed
in a different position and in another implementation it is placed in another position
in the previous known state of art This invention gets together two different implementation
on a single injector holder (5). Due to this oven and cooker producers can use this
invention without modifying security slot bores (6.1) bored on the iron sheet (6)
placed on ovens or cookers.
[0028] Grooves (5.7) having a specific tapered profile minimum two units distributed radially
are used in perspective view of the injector holder of the burner (5) used in the
invention on Figure 8. These grooves (5.7) may be used as four units preferably. The
α angle of this said groove is between 20° and 80° relative to A axis and inclined
around 60° preferably. The invention is designed such that when the above said big
flame crown (4) is joined with the injector holder, a volume (7) is formed when the
groove of the said injector holder (5.7) is joined with grooves (4.1) located at the
bottom of big flame crown (4). Inlet orifice (7.1) of this volume provides primary
air suction from external environment by staying at the top of iron sheet (6) of oven
or cooker. The outlet orifice of this volume (7.2) is opened to mixing chamber of
the injector holder (5).
[0029] There are walls (5.8) rising around the grooves (5.7) of the injector holder (5)
at the surrounding of the groove of the injector holder of the burner. Turning of
big flame crown (4) to right or left is prevented by clamping the level (4.2) of grooves
(4.1)located at the bottom of the big flame crown (4) by means of elevating these
walls (5.8) with a certain angle. An angle relative to B axis of the elevated walls
(5.8) is between 5° and 45° and inclined an angle around 10° preferably. The injector
holder (5) and the big flame crown is connected to each other in the way that is explained
in above.
[0030] There is bore (4.3) located in the middle center of big flame crown (4) and created
venturi effect. There is a certain tapered angle in this bore (4.3). By way of mixing
this flammable gas exiting from the orifice of injector (2) and air that comes from
the exit orifice (7.2) of the volume (7) from which primary air comes are suctioned
towards above from this bore (4.3). Four air grooves (4.4) minimum two which provide
secondary air suction those look like slices so as triangle distributed radially around
the bore (4.3) located at the middle center of big flame crown(4). These air grooves
(4.4) in the invention provides air feeding of ports (3.1) of small flame crown (3)
and inner ports (4.5) of big flame crown (4) by suctioning secondary air from external
environment from just external side of iron sheet of oven and cooker (6).
[0031] The purpose in here is to prevent the cutoff of the secondary air by saucepan or
pan located multi-burning burner (1) during cooking on oven or cooker. If the secondary
air is not suctioned into the system, the feeding the ports of small flame crown and
inner ports of big flame crown will be cut and these ports will be turned off. The
emission rates of burner will be increased by blowing unburned gas to environment.
[0032] There are four grooves (4.6) as minimum two distributed radially in the inner side
of big flame crown (4). Side walls (4.7) of this groove (4.6) is made in the form
that it will be leveled. The side walls (3.8) of four air grooves (3.2) minimum two
grooves which are distributed radially located at the bottom of small flame crown
(3) are designed to be engaged inside of four air grooves (4.6) at least two grooves
distributed radially inner side of big flame crown (4). Ω angle of top walls of (3.9)
said grooves (3.2) are inclined between 2° and 25° preferably 5° to C axis. Small
flame crown (3) and big flame crown (4) are attached to each other by this way. Turning
of small flame crown (3) to right or left is prevented by locking it to the big flame
crown (4) in this way. A second volume is formed by the engagement of side walls (4.7)
of four grooves (3.2) minimum two distributed radially and located at the bottom of
small flame crown (3) into side walls (4.7) of four grooves (3.2) minimum two distributed
radially located inside of the big flame crown (4). The said volume (8) provides feeding
of ports (3.1) of small flame crown (3), inner ports (4.5) and outer ports (4.8) of
big flame crown(4) by the suction of primary air/gas mixture that comes out from the
bore (4.3) located at middle center of big flame crown (4) and that creates vertical
venturi effect by this volume (8). Before the primary air/gas mixture that comes our
from the bore (4.3) that creates vertical venturi effect fill into the second volume
(8) acts towards the said volume by striking to the bottom surface (3.3) located at
the center of small flame crown (3) and creates horizontal venturi effect. A part
of primary air/gas mixture reached to upper surface (3.5) of small flame crown (3)
by coming out from four bores (3.4) minimum one distributed radially around the center
of small flame crown (3). The primary air/gas mixture that comes our with a certain
form from here is provided to come out from ports (3.1) of small flame (3) crown by
striking to the cover of small flame (9). The exit of the other part of the primary
air/gas mixture from the inner (4.5) and outer (4.8) ports of big flame crown (4)
is provided by continuing its movement, coming out of outlet orifice (8.1) second
volume (8), striking onto the big flame cover (9) located on big flame crown, distributing
into peripheral groove located into big flame crown (4).
[0033] Burning of the system is provided by ignition unit (12) placed to an ignition unit
slot (5.4) located for providing the attachment of ignition unit to the invention.
The burning together with ignition starts in outer port (4.8) and inner port (4.5)
of big flame crown (4) of the burner (1). Inner ports (4.5) of big flame crown (4.5)
is located such that burning is provided in outer ports (3.1) of small flame crown
(3)immediately after the initial ignition. 10
[0034] Another specification of the invention is that the area of outlet orifice (8.1) of
second volume (8) is between 1 % and 15 % preferably around 3 % of total area of peripheral
groove (4.9) located in big flame crown.
[0035] Another specification of the invention is that at least the area of one of the bores
from four bores (3.4) distributed radially around the center of small flame crown
(3) is between 1 % and 10 % preferably around 2 % of the total area of the upper surface
(3.5) located at the center of small flame crown (3).
[0036] Another specification of the invention is that the angle γ of the angled surface
(3.6) located at the end of the bottom surface located at the center of small flame
crown and creates horizontal venturi effect is inclined between 20° and 70° preferably
around 50° relative to A axis.
[0037] Another specification of the invention is that the distance between surface(4.3)
at the end of the bore (4.3) that created vertical venturi effect in big flame crown
(4) after small flame crown (3) is mounted to big flame crown (4) and bottom surface
(3.3) located at small flame crown (3) and creates horizontal venturi effect is between
1 and 10 mm preferably around 2.5 mm.
[0038] Another specification of the invention is the burning may be increased or decreased
in small flame crown (3) by changing diameter of the ports of small flame crown (3).
This change may only be possible by changing small flame crown (3).
[0039] Another specification of the invention is that ϕ angle of external surface (4.11)
that covers the bore (4.3) which creates vertical venturi effect at big flame crown
(4) is inclined between 5° and 45°, preferably 10° relative to A axis.
[0040] Another specification of the invention is that there are at least four elevations
(3.7) distributed radially to outer periphery of the ports of small flame crown (3).
The external diameter distances of these elevations (3.7) to each other is smaller
than the internal diameter of big flame cover (10) Sliding of the big flame cover
(10) to the ports of the small flame crown (3.1) is prevented by this way. Also another
purpose of this elevation (3.7) is to prevent turn off of these ports (3.1) by closing
small flame crown ports (3.1) directly with their bottoms, in case of saucepan, pan
or pot with small diameter are put on the burner.
