Description

Electric cooker

The present invention relates to an electric stove adapted to be powered from a battery or batteries.

In countries with strong sunshine, it is advantageous to produce your own electrical energy, and therefore to use it for cooking. In African countries, people often use wood for their cooking needs, which is a cause of significant deforestation. In addition, the production of electrical energy is also often a problem, the power grid is often subject to cuts. Heating food is therefore a real problem in Africa.

Features and details of a preferred embodiment will become apparent from the following detailed description in which reference is made to the accompanying drawings.

In these drawings, - Figure 1 is a schematic perspective view of a range according to the invention with tearing; Figure 2 is a rear view of the cooker of Figure 1; - Figure 3 is a schematic view of the limiting device of the range of Figure 1.

FIG. 1 shows schematically an electric cooker (1) adapted to be powered from batteries (2) (for example 12 V, 24 V batteries, these batteries being either connected in parallel and / or in series, for example to increase voltage), in particular rechargeable batteries (for example rechargeable from energy derived from photovoltaic energy), said range comprising at least one electric oven (3) with an electric heating resistor and at least three cooking plates (4) electric, said range having a limiting device (5) limiting or preventing the supply of electric power to one or more electric plates when the operation of the electric oven is required, in particular when the electric power supply for the heating resistor of the oven is required. The electrical resistances are advantageously modified according to the voltage of the energy source (batteries) and its maximum power.

To ensure proper operation of the electric range, the limiting device (5) limits or prevents the supply of electrical power for one or more electric plates as soon as the electric oven is put into operation or when the electric current is supplied to the resistor electric oven heating. Indeed, experience has shown that it was necessary to avoid allowing the energy input to all the plates, when the oven is to be used.

The limiting device (5) comprises a manual control means (50), such as a selection button, movable between at least a first possible operating position of the oven (3) advantageously with at least one electric plate (4A), and a second position of possible non-operation of the electric oven (3), but of at least two electric plates (4B, 4C). This selection button is advantageously movable in a position preventing any supply of electric power to the furnaces and hotplates. For example, this button 50 is movable between a position allowing the passage of current to the distributor 51 (to supply the plates 4B, 4C and 4D), another position allowing the passage to the distributor 52 (to supply the plate 4A and the oven 3) and a third position to prevent the flow of current to the distributors 51, 52. Depending on the power level of the batteries (2) and whether the oven is used or not or whether the oven is 3), the distributor 52 is electrically connected to the distributor 51.

The limiting device (5) comprises an automatic control system (60) adapted to allow a power supply of at least two electric plates as soon as no current is required by the electric heating resistance or heaters of the electric oven or as soon as the amount of current required by the heating resistor (s) of the electric oven is less than a predetermined amount. Indeed, when the oven has reached a predetermined temperature, it is possible to keep the inside temperature of the oven to a predetermined temperature, without having to use energy from batteries. It is therefore interesting to use the available electrical energy to heat one or more hotplates.

The electric cooker according to the invention as shown comprises means (6) for estimating the power of the batteries, and in that the limiting means (5) is associated with or comprises means (70) for preventing power supply of the or electrical resistances of the electric furnace (3) as soon as the estimated power of the batteries by said means is lower than a given power. This makes it possible to avoid consuming electrical energy if the power level of the batteries is in any case insufficient to allow a minimum temperature to be reached, or even to maintain a minimum temperature of the oven for a given period.

The electric cooker is in the form of a cooking element (10) having at least 3 cooking plates (4) and an oven (3), and one or more furniture (11A, 1BB) mounted removable relative to the cooking element (10), the or one or more furniture comprising a space (12) for batteries (2) connected in parallel and / or in series, and / or for the limiting device (5). This facilitates the transport of the cooker and its assembly. Since the cook is particularly destined for Africa, it is important that its transport is the easiest.

The furniture (11 A, 1 IB) form a working surface (13), preferably left and right of the cooking element (10).

The furniture (11A, 1BB) is attached to the cooking element by a locking system (12A, 12B), said locking system being preferably adapted so that in the event of an attempt to unauthorized opening of the locking, a safety means (80) is activated to prevent electrical operation of the cooker. This locking system is advantageously present both front side and rear side of the stove. Such locking serves on the one hand antitheft system (the weight of the assembly becoming too heavy for easy transport, while its size makes it difficult to move in a staircase), but also a security system to prevent the operation of the Cook.

In particular, said locking system is preferably adapted so that as soon as or as soon as the locking system is in the unlocked position, a security means (80) is activated to prevent electrical operation of the range. The cooking element (10) is connected to a piece of furniture or furniture (11 A, 1 IB) via one or more electric cables (15), advantageously housed in a protective section (16). These / these cables advantageously extend from the rear side of the cooker, in particular at a location substantially inaccessible from the upper face of the cooking element.

Thermal insulation means (17) (for example in the form of an insulation blanket) extends between the cooking element (10) and each of the furniture (11 A, 1 IB), while the furniture (11 A, 1 IB) adjacent to the cooking element (10) advantageously have a profile (18) adapted to extend above the thermal insulation means (17) and above a substantially horizontal face of the cooking element (10). This profile 18 protects the insulating layer 17, all to prevent liquid materials can flow under the profile in an insulating layer. For example, the upper edge of the insulating layer is inclined forwardly with respect to a horizontal plane, or is associated with a channel inclined forwards with respect to a horizontal plane to possibly evacuate liquids that would be present above insulation 17.

The electric range comprises a charging system (19) or batteries from photovoltaic panels, said recharging system being advantageously placed in a space of one or furniture (11 A, 1 IB), the range being associated or preferably comprising a connection cable (20) adapted to cooperate with an electrical plug (21) of one or furniture.

The electric range comprises at least one or furniture (11A, 11B) with rails (22) adapted to support one or more batteries (2) or a tray carrying one or more batteries, one or rails being associated with a locking system (23), in particular which can be the locking system of a piece of furniture to the stove. The locking system 23 may also a system preventing in the open position or in case of attempted break-in, the flow of current to the heating elements.

The side cabinets 11 A, 1 IB may also be associated with jacks 25 connected to the batteries, in particular via the Mimic device 5, for example in certain positions of the limiting device.

The side cabinets (11 A, 1 IB) can each be provided with rails with or without a tray for receiving batteries. The cabinets are advantageously provided with doors (not shown) able to be closed with a locking system that can also serve as a safety means preventing the operation of the range in case of unauthorized door opening. The rear of the cabinets can be associated with a ventilation grille.
