All gas grill

The invention relates to an all-gas grill according to the preamble of claim 1. In particular It refers to an all-gas grill for large kitchens and restaurants, in which a quick and easy different Modes of operation aripassable device is required.

Known grills are preferably built for a single operating mode and usually provide one Little adaptability to different ways of preparing the dishes. On the other hand, devices that use a limited adaptability to Holriebsvar Lantc-n allow a lot of space, require extensive maintenance and are relatively expensive.

The object of the invention is therefore to provide one with different types of gas such as town gas, natural gas, propane gas, etc. To propose a heated grill, which is not only simple and clear, but can also be easily adapted to different application needs.

This object is according to the invention with a All gas grill solved, which is characterized by the features of claim 1. Preferred embodiment variants are defined by the dependent claims.

A particularly advantageous feature of the grill according to the invention is that it uses individually adjustable heating registers Different dishes can be prepared or prepared in a confined space with practically no mutual hindrance can.

A preferred embodiment of the invention is described below with reference to the drawing, for example. In it shows

1 shows a partially sectioned schematic perspective of a grill according to the invention,

Fig. 2 schematically shows the lower heating register in section along the line II-II in Fig. 1, and 3 schematically, the upper heating register in section along the line III-III in FIG. 1.

Fig. 1 gives an overall view of the grill with two in one that can be operated with several types of gas Housing generally designated 1, superposed heating registers 2 and 3-.

The lower heating coil 2, which is shown in Fig. 2 in more detail. Is designed as a flat tubular structure and provided with gas outlet nozzles ¹ J, 5 containing longitudinally oriented and mutually spaced distributor tubes 6, which are welded on both ends in a respective Kollektorröhr. 8 The latter are connected to the grill housing 1 by means of connection elements (not shown) in such a way that the lower heating register 2 is fixed in the housing 1.

Of the distribution tubes 6, 7 contains the middle one

- γ- Γ.

Distributor pipe 6 each have a lateral row of nozzles H provided for horizontal gas outlet. The two outer distributor pipes 7 each contain a row of horizontal nozzles 4 which are opposite the nozzles 4 on the central distributor pipe 6. This results in two flame beds 9, each fed by two rows of nozzles, for dissipating heat upwards and downwards. The outer manifold tubes 7 further contain a respective series of vertically ^s * which can be closed or valve slide plates 10 selectively opened up ^/ "pointing nozzles 5. The valve slide plates 10 shown schematically in FIGS. 1 and 2 are connected via a manually operated shift linkage 11 and a handle 11 'can be brought into their release or locked position at the same time.

Lift the flame beds 9 between adjacent ones

Distributor tubes S ₃ 7 and supported on these latter a heating grid 12 is arranged, which is heated by the flames from the nozzles 4 and which radiates the received heat in good distribution upwards and downwards. The heating grids are made up of intersecting metal rods and, in addition to short-term heat storage, aim to avoid local overheating of directly or indirectly heated food to be grilled.

The upward-facing ones that can be switched on and off

Nozzles 5 on the outer manifold pipes 7 serve before In particular, the edge zone direct heating of the grilling goods receiving means located above the lower heating register 2. By closing these nozzles 5, an increase in gas pressure is caused in the distributor pipes 7. This means that there is more gas

from the remaining open nozzles 4 of these tubes 7, wherein as a result of an increase in the heating power from below, the heating grids 12 are heated more intensely. The ones of these This increases the amount of heat radiated downwards, while the amount of heat radiated upwards increases as a result Elimination of direct heating by flames from the nozzles 5 is reduced by approximately the same amount.

The gas is fed in from a connection point (not shown) that is built into the rear wall of the housing from a main supply line 13 to which the feed line is connected via a regulating valve l4 on the front of the grill housing 1 15 of the lower heating register 2 is connected.

The lower heating register 2 are shown in FIG lower support arrangement 16 and an upper support arrangement 17, each made up of two L-profiles, which are at a distance from the heating register 2 in pairs at the same height on the two housing inner walls 19, 20 are attached. Im shown For example, the lower support assembly 16 carries a grill pan 21 which can be pulled out of the grilling space 22, and the Upper support arrangement 17 is a broken grill plate 23, which is also pulled out of the grilling space 22 can be. It goes without saying that instead of different grilling items receiving means also optionally the same are used, (i.e. two grill pans 21 or two grill plates 23) or the grill pan 21 above and the Grill plate 23 can be inserted below.

The upper heating register 3, of which Fig. 3 shows a sectional view, is expediently a self-contained

closed elongated rectangular round pipe construction, in which pipe sections 25, 25 'on opposite sides Sides are essentially parallel to each other. Both those running in the longitudinal direction of the grilling space 22 Pipe sections 25 and the (shorter) pipe sections 25 'running at right angles thereto each have a number approximately evenly spaced nozzles 24 inclined at an angle of about 30 ° outwards and downwards. Of the two short pipe sections 25 'one is provided with a gas supply line 26 which the housing inner wall 19 through the Slit 27 passes through and is connected to a regulating valve 28. This is via a flexible supply line 29 connected to the main supply line 13.

The upper heating register 3 is continuously adjustable in an appropriate range in the direction of the arrow "A". For this purpose, as can also be seen from FIG. 3, in held a sliding guide, the two perpendicular to the short pipe sections 25 'welded guide sleeves which can be moved up and down along a respective guide rail 32 by means of a pivot lever arrangement 31 shown schematically in FIG. 3.

The height adjustability of the upper heating register 3 basically enables three different operating modes for the grill according to the invention:

1.Heating register 3 at the top:

The housing cover plate section 33 over the grilling space 22 is by the heating regi

ster 3 warmed rising heat and is as

Plate and / or plate warming surface can be used. On a medium altitude Support arrangement 34 (such as 16 and 17) can be a grill pan or grill plate 35 such as 21 or 23 are used and the food to be grilled is heated by direct heating from the nozzles 24 will. Optionally, the grill plate 35 can serve as top heat for food to be grilled is in a grill pan on the Auflageran-order 17 of the lower heating register 8.

2. Heating register 3 in a central position: On a support arrangement 36 above the A grilling pan or grill plate 38 can be placed on the heating register 3: Heiz

register 3 as bottom heat. A grill pan is also placed on the support arrangement 34 or a grill plate 35 attached: heating register 3 as top heat. At most that's enough "from the grill plate 38 · continue upwards- '

Flowing heat for heating the housing cover plate section 33 as a plate heating surface the end.

In operating modes 1 and 2, the lower heating register 2 can be operated independently.

3.Heating register 3 at the bottom:

The support arrangement 34 is not used and the heating register 3 works as top heat

for food to be grilled in a

-1.

Order 17 located grill pan or grill plate 23, the lower heating register 2 works as bottom heat. Here are also the two different heating options through the vertical nozzles 5 in

the outer distribution pipes 7 of the lower heating register 2 applicable. The grill works in the manner of a top and bottom heat cooking or baking device.
