Heat generating base from electrical resistance and food preparation apparatus.

This disclosure relates to a patent for heat generating base and apparatus for preparing

5 foods obtained from the base, which belong to the household appliances field and were developed to provide the market with another option for the optimal preparation of heat foods, particularly meat.

The modern lifestyle demands practical and efficient solutions to people's basic needs. Among these needs

Undoubtedly, this includes food. As a result, there is, among others, a wide variety of household appliances designed to optimize food preparation.

These include one essentially comprised of a heat-retaining and circulating cylindrical

The food reception consists of two collapsible parts: the lower part is provided with a lower central opening which receives the heat source and an upper part is provided with a set of upper openings consisting of: a larger central opening for the introduction and removal of food skewered or arranged in grids. , alignment of smaller holes arranged around the

Central opening comprising mounting holes for the spits or grilles communicating with the central opening and exhaust holes interspersed with Further, said apparatus is further comprised of a lid closing the upper central opening of the housing; heat diffuser inside the housing and above the heat source; and by a plurality of upright skewers and grids, each formed by the portion receiving the food, cable and support disk in the carcass mounting hole, said skewers or grilles are with the portions supporting the food within the housing. housing, the discs retained in the housing mounting holes and with the cables projected out of the housing.

This appliance has as its heat source the flame of a gas burner of a stove. Thus, the bottom of the lower part of the carcass around the central opening is supported by the support of a gas cooker mouth; the central opening is above and vertically aligned with the gas burner and is traversed by the flame; and the diffuser inside the carcass and the geometry of the carcass together, favors the homogenization of convective heat that acts on foods supported by vertical skewers and / or grids.

Despite the good results obtained with the above device, studies have continued to give it new facilities.

Within this, it was noted the need to provide the device optionally with electric heat source.

Thus, the object of the present patent, is to provide a heat generating electrical base for the formation of a food preparation apparatus.

Another objective is to provide a food preparation apparatus using the electric heat generating base.

Another objective is to provide a base and apparatus that, besides meeting the needs of the market, are not therefore of construction or manufacture with levels of complexity that make them uninteresting.

Another objective is to provide an adequate acquisition and use cost base and apparatus.

Therefore, in view of the above aspects and objectives and in order to serve them, the heat generating base and the food preparation apparatus obtained with the base, objects of the present invention have been developed. The electric generating base is essentially comprised of: substantially disk-shaped housing, the upper face of which forms a bearing face in the center of which is mounted a special vertical shaped electrical resistance of extending meanders around it. of a central space; said housing incorporates electrical power regulation and supervision devices and derives from it the electric power cable; This base is furthermore comprised of a carbon and ash plate mounted in the central region of the upper face of the carcass under the and support a portion of coal that is retained within the central space defined by the resistance.

The food preparation apparatus is comprised of the base and a base-mounted cabinet, which may have any suitable configurations. Preferably, the cabinet is formed by the carcass and the vertical skewers and / or grilles, which comprise the usual apparatus whose heat source is a flame from a stove gas burner described above.

The food preparation apparatus comprised of the electric base and preferably of the housing and vertical skewers and / or grids above, solves the limitation of the usual apparatus formed by the heat source housing, diffuser and skewers and / or grilles in the form of a flame, since in the present apparatus the heat source is the electricity provided by the electric base; said apparatus thus having greater field and application flexibility.

Each spit and grid mounting hole 60 is formed by an enlarged section 60 ', on which the spit or grid is retained, and from which extends the radial narrow section 60' which connects to the central opening 59.

The skewers 70 are of the type formed: by rod 72 which is stuck through the food; cable 73; and a spit support disc 74 in the bore 60 of the housing 51. In another possibility, the spit 70 may be of the "inverted" type, that is, substantially in the form of a trident 75, whose side rods receive the food and the rod The central unit has mounted the cable assembly 73 and backup disc 74.

The racks 71 are of a type essentially formed by two hinged racks 76 between which the food is secured, connected at a lower hinge, by upper lock acting between the racks and by the cable assembly 73 and retaining disc 74 mounted on the upper side. of one of the grids.

Thus, when the food preparation apparatus 100 is in use (fig. 10), the electric heat generating base 1 is supported on a surface and connected to the power supply network. The housing 51 has the bottom 54 of its lower part 52 resting on the upper support face 5 of the base 1 so that the electrical resistor 11 thereof is disposed in the lower center opening 55 and projected into the housing 51. The upper part 56 of the housing 51 is mounted overturned in the mouth of the lower part 52 defining a chamber. The ash charcoal plate 20 is mounted in the center of the support surface 5 of the base 1 under the electrical resistor 11 (fig. 2). Within the space 15 of the electrical resistance 11 and on the plate 20 is disposed a portion of charcoal 30. The skewers 70 and / or the grates 71 receive 200 portions of the food to be prepared and in this condition each skewer 70 and / or grill 71 , containing a portion of food 200, is introduced into the central upper opening 59 of housing 51, coupled and radially displaced in respective bore 60, where it is mounted hung through the support disc 74 so that food 200 is within the housing. 51 and the cable 73 of said spit 70 and / or grid 71 is projected out of it. The set of skewers 70 and / or grids 71 containing the food portions 200 are around the electrical resistor 11 containing the charcoal 30. The cap 62 is applied and closes the central opening 59. Under this condition, the electric heat generating base 1 is switched on and its resistance 11 generates heat and radiates 300 within the chamber defined by the housing 51 and the charcoal 30 is lit, so that the food disposed within the housing 51, assembled on skewers 70 and / or blades 71, are roasted by radiant heat from electrical resistance 1 1 and flavored with charcoal 30. Residues from food 200 such as fats and liquids are trapped in the trough-shaped bottom 54 of the carcass 51

Within the basic construction described above, the heat generating base 1 and the housing assembly 51 and skewers 70 and / or grate 71 forming the apparatus 100, object of the present invention, may have modifications regarding materials, dimensions, constructive details. and / or functional and / or ornamental configuration, without departing from the scope of the requested protection.

In addition, in addition to the usual version, consisting of housing, diffuser and heat-source vertical skewers and / or grilles consisting of the flame of a gas burner of a gas cooker, this type of food preparation apparatus may be used. consisting of apparatus 100 of the present invention formed by the electric heat generating base 1 and the housing assembly 51 and vertical skewers 70 and / or grids 71 which use as a heat source electric energy. Optionally, the electric heat generating base 1 can be supplied in isolation to the consumer market to provide that existing standard appliances can be used in either gas or electric form, all of which broaden the range of applications and options.
