[0001] The invention is of the type in which each burner uses a mixer or Venturi pipe in
which the gas issuing from a nozzle is mixed with a part of combustion air and sent
on to a head, or a ring.
[0002] Prior art realisations exhibit a cooking range, comprising cooking burners, which
is constituted by a dismountable drip tray which enables access to inside the apparatus
for maintenance or cleaning purposes.
[0003] It is in fact quite easy for liquids in the cooking recipients to spill over the
barrier, which in effect is the drip-tray, and penetrate into the apparatus, reaching
areas which are difficult to access for cleaning.
[0004] The tray, then, must be removable so that normal and not easy cleaning operations
can be carried out below the cooking range.
[0005] It is also very likely that, while removing the tray for cleaning, further dirt will
drop down onto the apparatus, penetrating inside it and causing even more cleaning
problems.
[0006] It is worthy of note that in the prior-art realisations, the burner arrangement is
fixed, as is the disposition of the spill trays, which exhibit various and different
seatings which are specially predisposed for the single burners - usually there are
bigger and smaller burners necessitating differently-sized seatings.
[0007] In other words, each tray is made specially for a predetermined burner arrangement
in which the burners are not identical.
[0008] This obviously leads to producing, for each cooking range, a number of trays, different
among themselves, which correspond to the combination and arrangement of the burners
(of different sizes and power) on a single cooking range.
[0009] The main aim of the present invention is to obviate the above-mentioned limitations
and drawbacks in the prior art.
[0010] More specifically, the invention both provides a cooking range which prevents dirt
from fouling the underlying parts and enables easy and rapid cleaning, as well as
simplifying production by standardising the characteristics of the drip tray which
is the base of the cooking range.
[0011] An advantage of the invention, connected with the ease of cleaning, is that the internal
part of the apparatus is protected from fouling, and is therefore free of unhygienic
matter.
[0012] Another advantage of the invention is the flexibility of burner arrangement on the
cooking range, which is not restricted by conformational necessities.
[0013] These aims and advantages and others besides are all attained by the invention as
it is characterised in the appended claims.
[0014] Further characteristics and advantages of the present invention will better emerge
from the detailed description that follows of a preferred but non-exclusive embodiment
of the invention, illustrated purely by way of nonlimiting example in the accompanying
figure of the drawing, in which:
figure 1 is a schematic plan view from above of the invention;
figure 2 is a schematic section made according to line II-II of figure 1;
figure 3 is a schematic section made according to line III-III of figure 2.
[0015] With reference to the figures of the drawings, 1 denotes in its entirety a cooking
range with gas burners 3 for apparatus for food cooking.
[0016] Each gas burner 3 uses a mixer pipe, scientifically known as a Venturi pipe, in which
the gas issuing from a nozzle is mixed with a predetermined quantity of combustion
air before being sent on to a ring 32a or 32b.
[0017] The gas burners 3 are sealedly mounted on a drip-tray 2 in which they are housed
in seatings 30.
[0018] In particular, a terminal part (outlet mouth) of the mixer pipe of each burner 3
is stably and sealedly coupled in each seating 30, while the head or gas ring 32a
or 32b is coupled by simple resting, and can be removed in a vertical direction.
[0019] The seatings 30 of the drip tray 2 are identical to one another, so that each of
them can house different burners 3 of different power rating.
[0020] Each seating 30 can be equipped with fittings that enable them to couple only with
one kind of burner 3, of a predetermined power rating.
[0021] In the illustrated embodiment two fittings can be equipped, characterised by two
different positions with respect to the seatings 30, inasmuch as it is envisaged that
in each seating 30 two different types of burner 3 can be coupled, characterised by
two different power ratings.
[0022] In other embodiments of the invention, it is possible to provide a system of fittings
which allows each seating 30 to receive a predetermined number of burners 3 (more
than 2) characterised by having different power ratings.
[0023] Each fitting is predisposed to enable coupling with only the gas ring 32a or 32b
of a burner 3 of predetermined power rating and is constituted by a pivot 31 which
can be fixed to the drip-tray 2 in one of the two predetermined positions with respect
to the seating 30.
[0024] These two different positions are determined by the two coupling holes 35 and 36
located by the side of the seatings 30 in each of which the pivot 31 can be inserted.
[0025] The pivot 31 couples in special seatings 33, 34 afforded in two different types of
gas rings 32a and 32b which are parts of two differently-rated burners (ring 32a is
larger and equips a higher-rated burner).
[0026] Since each type of burner 3 has a precise and single coupling position in a single
seating 30, the presence of the reference pivot 31 in the hole 36 enables coupling
in the seating 30 corresponding only to the gas ring 32a of the burner mounted on
the same seating 30.
[0027] Similarly, the presence of the reference pivot 31 in the hole 35 enables coupling
of only the gas ring 32b of the burner mounted in the same seating 30.
[0028] Thus no error can be made during assembly.
[0029] In a further embodiment (not illustrated) of the invention at least one fitting for
a burner of a given power rating is constituted by a plurality of pivots positioned
in a plurality of holes by the side of the seatings 30. The relative positions of
the pivots enable a dedicated fitting for only one type of burner to be set up.
[0030] The accessories for igniting and controlling the flame (thermocouple, ignition and
pilot light) are located at a same distance from the respective seatings 30 on a single
drip-tray 2 and form, for each burner 3, a flame ignition and control group 4 which,
located at a fixed distance from the respective seating 30, is removably connected
to the drip-tray 2 by means of a fixed and sealed coupling.
[0031] Each flame ignition and control group 4 is also protected from above by a cover 5
fixed to the support grill for the cooking recipients, usually located removably above
the drip-tray 2 and the burners 3.
[0032] The drip-tray 2 is fixed and, being sealed, does not allow any dirt to permeate through
into the parts underlying the apparatus.
[0033] The whole assembly is easy to clean and problem-free as far as the remounting of
the gas rings is concerned, which is error-proof in the sense that no ring can be
inserted in a seating housing a burner which is different from that on which the ring
is to be fitted.
