Description

The invention relates to an all-gas grill

  carrying an envelope, two horizontal heaters

  which can be put into service, independently of any other

  and a cooking chamber formed in the envelope, which opens towards the service side, the side walls of which are provided with support devices for the placement of containers or the like intended for

  receive the dishes to prepare. It relates in part

  bottom to an all gas grill for large kitchens and restaurants

  taurants in which it is necessary to have

  a device that can be quickly and conveniently adapted

  has different modes of operation.

  The grills already known are preferably constructed for a single mode of operation and, in most

  cases, they have only a weak capacity to adapt

  different ways of preparing food.

  Furthermore, devices which admit an adaptive capacity limited to operating variants

  are relatively bulky, require extensive maintenance

  bearing and are relatively expensive.

  The object of the invention is therefore to propose a grill which can be heated with different kinds of gas.

  such as town gas, natural gas, propane, etc.

  which is not only of simple and easy construction but also easily adaptable to different needs of use, According to the invention, this problem is solved with an all gas grill which is characterized in that the heating bodies are arranged one above each other in the cooking chamber, in that the lower heating body has first outlet openings

  horizontally oriented gas and second or

  vertically oriented gas outlet vertices,

  that the vertically oriented gas outlet openings

  can be selectively closed or released

  using a slide, in that above the pre-

  first gas outlet openings of the lower heating body is arranged a heating grid which accumulates the heat and transfers it up and down and in

  that the height position of the upper heating body

  can be adjusted in relation to the heating body

continuously lower.

  A particular advantage of the grill according to the invention is that, thanks to the individually adjustable heating bodies, it is possible to produce or prepare different culinary preparations in an extremely small space,

  practically without that. these preparations do not bother

kills,

  Other features and advantages of the invention

  tion will appear during the description which follows

  vre. In the accompanying drawings, given only by way of example

  ple: Fig, 1 is a schematic perspective view, partially broken away, of a grill according to the invention;

  Fig.2 is a schematic view of the heater body

  fe lower, in section along the line: x-II of Fig. l 1 and Fig, 3 shows schematically the upper heater, in section along the line III-III of

Figl.

  La'Fig. 1 gives an overview of the grill which can

  be supplied with several kinds of gas and which includes

  te two heating bodies 2 and 3 arranged one above the other in an envelope designated as a whole by the reference 1, The lower heating body 2 which is shown in Fig, 2 with more details present the shape of a

  flat tube construction and is fitted with distri-

  stopers 6,7 oriented longitudinally, placed at a distance from each other and comprising gas outlet nozzles 4,5,

  these distributor tubes being welded at their two ends

  mites, each in a collecting tube 8. These col-

  readers are connected to the envelope 1 of the grill by means of connection elements not shown, so

  that the heating body 2 is fixed in the casing 1.

  Among the distributor tubes 6,71, the central distributor tube 6 comprises a lateral series of nozzles 4 provided for the horizontal outlet of the gas. The two external distributor tubes 7 each comprise a series of horizontal nozzles 4 which face the nozzles 4 of the central distributor tube 6. In this way, two flame beds 9 are obtained, each supplied by two rows of nozzles and which emit heat up and down. The external distributor tubes 7 comprise are directed to be closed obturators represented to be brought ment or in diary of in addition each one a series of nozzles 5 which vertically upwards and which can or opened selectively by sliding plates, The obturating plates 10 schematically in Figs, 1 and 2 can

  simultaneously in their release position-

  their obturation position through

  li linkage operated by hand and

of a handle 11 '.

  Above each of the flame beds 9 comprised between the neighboring distributor tubes 6,7 is disposed a heating grid 12 which bears on these tubes, this grid being heated by the flames

  leaving the nozzles 4 and radiating the heat thus absorbed

  open up and down with good distribution.

  - The heating grates are composed of metal bars-

  intersecting liques and, apart from an accumulation

  short of heat, their purpose is to avoid over-

  local product heating - grilling which is heated di-

directly or indirectly.

  The nozzles 5 of the exterior distributor tubes 7 which are directed upwards and can be opened or closed are used above all for direct heating of the marginal zones of the containers of grilling products which are located below the lower heating element 2. By the closure of these nozzles 5, it causes an increase in the pressure of the gas in the distributor tubes 7r In this way, more gas comes out of the nozzles 4 of these tubes

  7 which remained open and, as a result of the increase in

  ment of the heating power from below, we obtain a stronger heating of the heating grates 12. The quantity of. heat radiated downward by these grates is thus increased while the amount of heat radiated upward is reduced to the same extent as a result of the removal of direct heating by the

flames coming out of the nozzles 5.

  The gas is transported from a

  fitting not shown, mounted in the rear wall of.

  the envelope, via a main inlet pipe 13 to which the supply pipe 15 of the

  lower heating element 2 is connected via

  diary of an adjustment valve 14 provided on the front face

of grill envelope 1.

  According to Fig, 1, there is provided a lower support device 16 and an upper support device 17 each of which is composed of two L-shaped profiles, which are combined with the lower heating body 2 and are fixed in pairs to the two interior walls 1R , 20 of the envelope,

  away from the heater 2. In the example shown

  tee, the lower support device 16 carries a tray

  21 that can be removed from the cooking chamber

  sound 22 and the upper support device 17 carries a plate

  that cooking 23 shown with cutaway and that can also be removed from the cooking chamber 22. It goes without saying that in place of djspositîfs of supports for products to grill different from each other, one can also use identical devices That is to say either two baking trays 21 or two baking trays 23) or that the baking tray 21 can be placed in the upper position and the baking tray 23

in the lower position.

  The upper heating body 3, of which Fig. 3 is a sectional view, is advantageously constituted by a closed rectangular construction, of elongated shape, made of round tubes, in which sections of tubes, 25 'extend respectively slightly. close parallel to each other on opposite sides. Both the sections of tubes 25 which extend in the longitudinal direction of the cooking chamber 22 as well as the sections of tubes 25 '(shorter) which extend perpendicular to the former are each provided with a number of nozzles 24 , uniformly distributed, inclined obliquely towards

  outside and down, with a slope of about 30.

  One of the two short sections 25 ′ is provided with a gas inlet pipe 26 which passes through the interior wall 19

  of the envelope passing through the slot 27 and which is connected

  cord 1 an adjustment valve 28. The latter is connected to.

  the main inlet pipe 13 via a flexible inlet pipe 29, the body of the upper heater 3 is continuously adjustable in height over a certain range, indicated by the arrow A. A this effect and as it emerges from Fig.3, it is held in a slide which includes two guide sleeves 30 welded to short tube sections' and which can move up and down, each along of a guiding amount 32, under the action of a device 31. Pivoting lever which is represented

schematically in Fig. 3.

  The possibility of adjusting the height of the upper heating body 3 makes it possible essentially to adopt three different operating modes for the grill according to the invention: the heating body 3 in the extreme high position the part 33 of the upper plate of the envelope located above the cooking chamber 22 is heated by the

  heat rising from the heater 3 and can be used

  designed as a warming and / or plate warming surface.

  248850o3 G On a support device 34 (analogous to the devices

  16 and 17) placed at a medium level, one can place a

  tin or a baking sheet 35 like the tray 21 or

  plate 23 and, on this tray or on this heating grid

  iron the product to be grilled by direct heating by the nozzles 24. The plate 35 can selectively serve as an upper heating element for the product 2 to be grilled, which is located in a grilling tray placed on the device.

  support 17 of the lower heating body 2.

  2 - Heating body 3 in the contrale position: on a support device 36 located above the body. heater 3, a tray or a cooking plate 38 can be placed. The heater 3 then works as a lower heating element. On the support device 34, a tray or a cooking plate 35 is also placed. This heating body 3 then works as an upper heating element. However, the heat which rises higher than the cooking plate 38 is sufficient. to heat the part 33 of the envelope which is used as a surface

dish warmer.

  This lower heating body 2 can be used

  read independently in working modes 1 and 2.

  3 - Heating body 3 in the low position: the support device 34 is not used and the heating body 3 works as an upper heating element

  for the product to be grilled contained in a cooking tray

  sound or on a plate 23 placed on the support device

  port 17, the lower body 2 working as a lower heating element. Here, it is also possible to use the two different heating possibilities by means of the vertical nozzles 5 of the external distributor tubes 7 of the lower heating body 2, The grill thus works at the way of a cooking appliance or a

  heating above or below.
