Abstract

Device for grilling in the catering industry with equipment for filtering or absorbing smells. Device for grilled food of the stated type, comprising an open-structure grillpan 6 heated from below or from above by a radiating means 7, and comprising a piece of equipment for filtering or absorbing smells 15, 16, 18, 19, 20, which sucks the air to be deodorised downwards, through the open-structure grillpan 6.

Description

 DEVICE FOR GRILLES El RESTAURÂT 101.

 The invention relates to a device for grilling in restaurants. It relates more particularly to a device of the type in question based on the principle of filtration of the emanations, such as smoke and fumes, which are produced during the cooking of food.

 Currently the devices sold for grilling food products are effective in terms of cooking food, but are often unsatisfactory in that they do not include a fume hood. Or when it exists, in that this hood is above the cooking surface, so that the assembly having a large size, remains not very mobile on the very place of tasting such as are for example the rooms restaurant.

The invention overcomes this drawback by causing a suction current reversed with respect to the natural direction of the fumes. In other words, we suggest sucking in the odors to be filtered through the same grid on which the grills are made from a forced suction. This solution has the advantage of leaving the volumes above the work area completely free, as well as considerably reducing the space requirement.
Advantageously and in practice, the entire grill is supported by a piece of furniture which encloses the device comprising a filtration block cooperating with an electric motor-aspirator group. This choice in the nature and structure of this device is essentially determined by the methods or the variants of use of the grills.

 The manner in which the invention can be implemented and the advantages which ensue therefrom will emerge more clearly from the embodiment which follows, given by way of non-limiting example, in support of the appended figures.

 Figure 1 is an elevational section of the grill assembly and its suction device and gas filtration.

 Figure 2 is a side view externally showing the entire embodiment.

 As is known, the grill by itself consists of a cooking grid heated by any means producing mainly infrared radiation. Most often this means consists of electrical resistances or a radiant panel supplied with a combustible gas. In the embodiment of the invention, this grid consists of a set of steel profiles (6) having the shape of an inverted "U" and inside which resistors (7) are housed. The assembly is formed of two heating zones by means of a half module for grills equipped with electrical resistances of the quartz type and a half module for grills equipped with shielded electrical resistances. The two kinds of resistance (7) being interchangeable in the profiles (o) from common supports not shown.

 The area adjacent to this equipment is supplemented by a set of reflectors (9) forming a screen for most of the radiation, which is thus returned to the grill. Each element of the reflector (9) has the same dimensions as each of the profiled elements (6) of the grid, so that the air can circulate through it, and also so that the excess of juice and fatty substances falling by gravity through can not dirty said reflective elements (9).

 The grilling assembly consisting of the parts (6) (7) and (9) is delimited by a sheet (5) fixed irremovable to a casing (8). This casing (8) which comprises on its front face the plate receiving the electric buttons (22) for controlling and regulating energy, is tiltable on the front as shown by the broken lines in FIG. 2.

 The reason for this tilting of the casing (8) is to access the interior of the cabinet (13) forming a sealed box. We see that this piece of furniture (13) rests at its lower part on two metal feet (23) and on two rollers (17) allowing the assembly to move more easily, and at the upper part, that it receives the tiltable casing (8) including grilling equipment.

 Inside this piece of furniture (13) whose walls are insulated (12) is a removable container (10) intended to collect the surpluses of juice as well as fatty substances (11) passing through the steel profiles (6 ) of the grid.

Said removable tank (10) rests on steel wire supports fixed on the sides of a filtration tank (18) so that there is sufficient air circulation space between the top of the tank filter (18) and the bottom of the fat and juice collecting tank (10).

 Figure 1 being in section we can see that the filtration tank (18) comprises the stratification of several elements which are: 1.) an openwork bottom made of a sheet of expanded metal (14). 2) a thickness of rock wool (20) having the function of retaining the dust from the filtered air. 3) a bed of activated charcoal granules (19) having the function of purifying the filtered air of impurities in general and in particular of the smelly substances which are conveyed therein. The characteristic of this treatment being in connection with the property of the active coals to absorb the very low doses of chemical components such as acrolein, putrescine, ammonia and ethylamine, which are evaporated by the combustion of fatty substances of grilled meats.

 Note that this tray (18) also removable can be taken out by the upper opening of the cabinet (13) when the casing (8) is tilted on the front, this in order to be able to conveniently replace the activated charcoal (19) during the episodic maintenance of the device.

 Finally, in the central part of the bottom of the cabinet (13) is an opening corresponding to the suction opening of a vacuum cleaner (15) driven by an electric motor (16), the said vacuum cleaner driving back to the ambient atmosphere l air after it has been filtered.

 To finish the description of the exemplary embodiment of the invention, and now referring to FIG. 2, we see that at the upper part of the cabinet (13) are fixed two steel tubes (2) which are bent in such a way that their lower end forms a handling handle while the upper parts are connected to each other by a piece (1> of steel wire supporting a shelf (2). Substantially halfway up the said steel tubes (2 ) is also a crosspiece (3) to which adheres a magnet element used for the storage of some instruments specific to the work of the cook.

 This embodiment being shown as already said without limitation, it is obvious that the device of the invention can be applied to any other grilling equipment of the type mentioned in the title. In other words, the invention can be applied to equipment for catering, in which the grilling grill would be heated by another means or a different arrangement than in the example of the embodiment. For example, it could be heated from a heating device located above the surface of the grid (6) so that the suction always takes place through the openings made in said grid.
