Roasting device movable.

Field of the Invention

This invention concerns a unit prepared for grilling industrially and that, on the one hand, has the property of being able to be moved from one place to another to work in each location autonomously and, on the other hand, and very especially, it offers special benefits aimed at providing better working conditions to the person in charge of serving the grill, which we will now call barbecue, in terms of preserving their health, as well as this grill will also substantially improve pollution environmental.

Prior art

Since ancient times, grilled food has been widely accepted and predicament, since this way of cooking provides the food with a crunchy surface in conjunction with interior smoothness and juiciness; when a fuel such as charcoal is used for the charcoal, an aroma is obtained which is especially appreciated.

However, this way of cooking has some easements that, although they have not been very questioned traditionally, nowadays they represent important inconveniences, since they affect such sensitive aspects as the health of the barbecue and the ecological damage due to environmental pollution and the waste of natural resources.

As for the health of the barbecue, the continuous proximity to a high temperature heat source and the exposure to the fumes produced not only in the burning of the fuel, with incomplete combustion processes, but very particularly in the burning of drops of fat and juices that permanently fall on the coals. Because of this, today it is proving difficult to find barbecue professionals.

One way to improve these painful working conditions has been the use of the electric grill, but at the cost of giving up some of the appreciated taste and olfactory properties that are obtained with grilled roasts.

As for the ecological damage, on the one hand the fumes themselves harmful to the barbecue are also for the atmosphere and, on the other hand, the misuse of natural resources is due to the loss of heat produced by the burning of fat dripping and juices, which, in addition to the noxious fumes, produces the cooling of the grill, lengthening the cooking time and, therefore, using more fuel than would be necessary to reach the roast point.

Explanation of the invention and Advantages

In the face of this state of affairs, the present invention has as its object a movable grill consisting of a grill that is formed by rods that have a downward inclination towards the front of the same and that, from back to front, have associated pletin channel channels in "V" that exceed the front end of the rods to place their tip on the vertical of a collection tank of fats and juices that is removably coupled in the front of a horizontal frame that supports the inclined frame of the grill and that is equipped with horizontal front projection means; because the roasting room has a glazed safety door with easy opening means for it to a horizontal position on the roof of the grill where the chimney of smoke outlet with its adjustable draft valve is; because there is a brazier equipped with means of frontal extraction by rolling which are combined with means of vertical displacement that are manually operated, and whose brazier has a refractory hearth that has a central hole in which an air blower is coupled; because there is a counterweight insulating gate that closes the home enclosure in which the brazier is located and which, by means of a rotating joint, extends below this home enclosure, being able to rotate between a vertical closing position and a consistent horizontal position in the one that gives continuity to the rolling plane of the rolling means of the brazier; and because the whole set is integrated in a rolling frame.

The main advantage of this proposed constitution lies in the particular configuration of the grill by the arrangement of rods and "V" channel plates that extend just and only under these rods. For a better understanding of the result that derives from such an arrangement, we must take into account that within a grill the transmission of thermal energy is produced by radiation (direct action of the heat source on the object) and by convection (energy which is transported by the movement of the air due to the temperature difference between the source and the environment). The tests carried out show that the best quality of the roast depends much more on the heat received by radiation than on the convection, so it must be that the piece to be roasted is exposed as much as possible to the radiation from the source of heat, that is the grill.

Well, precisely the arrangement of the invention allows most of the piece to be roasted, just the one between the rods, to receive heat directly due to radiation, while the vertical strips occupied by the pairs formed by each rod and its "V" channel plate, are opaque to most of the radiation; in such a way that between every two adjacent rods the piece to be roasted does not receive a uniform heat, but the temperature measured in this respect is distributed in the form of a bell that gives its highest temperature at its cusp, located in the center between the adjacent rods, and that decreases it progressively as it approaches each rod; The effects of this thermal distribution are beneficial in two ways: on the one hand, most of the surface of the piece to be roasted receives direct radiation from the heat source for the best quality of the roast, and on the other hand the relative cooling to the rods favors the dripping drifting towards them and falling into the "V" channel plates and not over the coals; the avoidance of dripping on the coals eliminates the production of the fumes due to their burning and which, as said before, are highly harmful to the barbecue and the environment, as well as avoiding the unwanted odors associated with said fumes and the expensive facilities that are usually necessary to evacuate them; In addition, a better caloric yield is obtained by avoiding the cooling caused by the burning of the continuous dripping of fats and juices on the coals.

The grill of the invention offers a compact constitution that favors a very tight construction against heat loss, where the glazed door allows to follow the progress of the roast without being subjected to the high temperature prevailing inside, in the same way as the possibility of extracting the grill and the brazier allow the comfortable loading and recharging of the roasting parts and combustible material in one and the other being exposed to a moderate heat perfectly bearable. On the other hand, when the grill is located in a closed location, it is not conditioned to uncontrolled external agents (air currents, ambient cold, etc.) ... roast temperatures of the order of twice that of a conventional grill are reached, which means halving the cooking time and obtaining a more juicy roasted product, because it has been exposed to fire less time and, therefore, has lost less juice; logically, the fuel consumed is also halved (less ecological damage and less economic expense) to obtain the same amount of production; being less heat losses also the grill lasts longer.

The design of this grill allows its installation indoors and outdoors, this last option being of particular interest because, since sparks cannot be produced outdoors, it is completely safe even on windy days. In this respect, the roasting concept of the grill is extremely advantageous considering the following reflection: today, when it comes to grilling, there are fixed installations, indoors or outdoors, or the classic barbecues intended for domestic use. that for grilling industrially, only fixed indoor or outdoor installations are available that require significant infrastructure that makes them very expensive and their own nature of fixed installations prevents their use from being adapted to weather stations; For this reason, catering establishments that have indoor and outdoor dining rooms are often forced to have two barbecue facilities, one indoor and one outdoor, which means doubling the cost of implementation and maintenance, a very bad use of the investment, where the outdoor installation can only be used for a small part of the year; and in the case of establishments in areas where there is usually good weather, if only outdoor roasting facilities are available, when there are days of bad weather they may have to give up roasting, and conversely, in areas where the weather is Differentiated according to the weather stations, there may be periods of good weather outside the strictly summer season, in which it would be desirable to have an outdoor roasting facility.

Given the high temperatures supported by the grill (1), for the greater structural and dimensional rigidity of the same it is foreseen that, at least in the front, between each rod (2) and its associated “V” channel plate

(3)

a vertical plate (14) is welded, an arrangement which is illustrated by the enlarged detail of Figure 3. This Figure 1 shows the temperature distribution curve line (26) experienced by the part of the piece to be roasted

(25)

between two adjacent rods (2), as well as the drip that occurs just inside the “V” channel plates (3).

According to the invention (Figures 1 and 2) the horizontal projection means of the horizontal frame (5) consist in that on each side of this there is an articulated parallelogram formed by a pair of connecting rods (15) having their upper ends articulated thereto and where the rear connecting rods of these pairs of connecting rods (15) extend beyond their lower joint and between their free ends have a first counterweight (16) installed. Figure 1 shows the extended position of the grill (1) mounted on the horizontal frame (5), where the connecting rods (15) are tilted forward and the grill (1) is remarkably offered for loading and recharging It can be carried out at a distance from the heat source where the temperature is moderate and not harmful to the health of the barbecue.

Figure 2 shows the working position of the grill (1) in which the connecting rods (15) are tilted backwards; in this position, with the door (6) closed, the roast is produced and the result of all the drips is poured into a grease-collecting tank (4) which, as illustrated in Figures 4 to 8, is removable (for emptying and cleaning) and attachable by means of quick coupling (27) and that when coupled, forms a whole with the horizontal frame (5) allowing its extraction by pulling on its own handles. The first counterweight (16) facilitates the passage from one position to another of the horizontal frame (5).

The visual comparison of FIGS. 1 and 2 clearly illustrates the constitution of said easy opening means of the glazed safety door (6), which consist of a broken profile arm (17) conveniently having an articulation. intermediate (18) and, at its free end, a second counterweight is hung

(19)

which facilitates the opening and closing maneuver of it.

According to another particular feature of the invention (Figures 9 to 11), the manually operated actuator means for vertical displacement of the brazier (9) consist of a single auger spindle (20) actuated from the front of the grill and that coils through each other. crossbars (21) whose wheel axles are mounted at their ends
