Description

FOOD COOKING SYSTEM CONNECTED TO AN APP VIA A WIRELESS NETWORK

FIELD OF THE INVENTION

The present invention is referred to the field of renewable energy. More particularly, the present invention refers to a system for cooking food that comprises different modules and within these a multifunctional, programmable and intelligent stove that optimally uses renewable energy in its operation and that makes various cooking functions available to the user. cooking that can be executed by the user directly or remotely through an application (app), where the stove communicates with a server, downloads updates to its operating software, keeps statistics related to its use and operation, manages the energy consumption during the cooking process and has connection and power ports to supply power to devices and household appliances for their operation or to recharge their batteries.

BACKGROUND OF THE INVENTION.

In the world it is estimated that more than 1.5 billion people lack access to electricity, especially in rural areas. For many isolated communities, mainly in third world countries, kerosene lamps and candles are the only way to illuminate their homes and rooms. On the other hand, it is estimated that around 3 billion people depend on wood and wood products to boil water or cook food, bringing not only serious deforestation problems associated with the indiscriminate felling of trees to be used in making charcoal or as firewood for cooking food, but also exposes people to the harmful effect on health caused by the gases and soot that are released during the burning or combustion of wood.

The situation for these isolated communities can still be worsened when wood is scarce in their surroundings, and access roads and distances do not facilitate the delivery of electricity or other types of fuel, such as liquefied petroleum gas or kerosene, which They can be used to cook their food or to light their homes.

Multiple technological solutions have been proposed seeking to provide these communities with solutions that allow them to boil water, cook their food or illuminate your homes and rooms without having to resort to cutting down trees, for example, solar stoves or ovens are known, with respect to which two main types are known in the state of the art, namely: box-type stoves that are based in a box that concentrates heat inside due to its reflective wings and adequate insulation, or its reflective silver interior that causes the ideal temperature increase to insert containers and heat food. They are basically thermal accumulators, they store energy from the Sun that reaches them and transfer it to the food container. These stoves, generally with transparent covers or tempered translucent material, cause a greenhouse effect inside that causes an increase in the temperature inside. Their main drawback is that their thermal performance is low compared to other types of solar stoves and concentration stoves, which, as their name indicates, use techniques for concentrating solar radiation and filters for ultraviolet rays at one point. with the purpose of increasing the temperature and achieving cooking of food and evaporation of fluids. They generally comprise one or more parabola-shaped structures built of a reflective material that is placed in the sun and allows all the rays to be redirected and sent to the point called focus, therefore, the place where the greatest amount of radiation will be concentrated. Concentration stoves represent an alternative for efficient solar use, however, their main limitation is heat transfer by convection, since the more heat is concentrated, the more losses due to convection there will be; which restricts them to latitudes where air currents are minimal, without failing to mention the inconvenience of heat transfer between materials generating heat deficiencies.

The truth is that this type of stoves that use sunlight for their operation have the main drawback that they cannot operate in twilight hours, in the absence of light or rain, since they do not have energy storage means and this without a doubt represents a serious limitation in its use and extension as a solution or alternative that fully satisfies the needs of users; In addition, another of the limitations they present is that they can only be used in cooking food and do not allow the solar energy that they manage to capture to be used for a different use than cooking food or boiling water. Other solutions are known in the patent literature that start from the principle of storing energy, for example solar energy, in a battery, to later use it in the food cooking process.

ADRIAN GOUGH KEITH in patent HK1253201 teaches a DC induction stove comprising a body and a charge controller disposed within the body of the induction stove, a rechargeable battery, a charge controller, a high frequency inverter, a regulator and an induction coil with feedback sensor; an outer surface of the induction stove body and a control panel; wherein the charge controller is electrically connected to the external solar panel through the solar panel input interface; the rechargeable battery is electrically connected to the charge controller, the regulator and the induction coil of the power sensor, respectively; The regulator is associated with a high frequency inverter and a control panel where the current heats an electrical resistance that induces a heating effect.

In patent CN203458202, inventor ZHANG CE discloses a solar electric stove that structurally comprises a solar cell panel, a controller, a storage battery, an inverter and an electric stove body. The solar panel is installed on a supporting frame, and the periphery of the panel is evenly provided with LED lamps. The direct current in the solar panel is transmitted to a controller through a cable. When a switch is turned on, the electric stove starts to work, the direct current in the solar panel is input to the inverter through the controller to become alternating current, and powers the electric stove through a wire; When the electric stove stops working, the direct current in the solar panel is input to the storage battery through the controller to be in reserve.

In patent CN203454225 LI TIANPING discloses a stove comprising a casing housing an electric ceramic stove, wherein a solar energy input interface and a power supply input interface are arranged in the casing; a solar power charge controller, a storage battery and an integrated UPS (uninterruptible power supply) charge-reverse machine, where the solar power input interface is connected with the solar power charge controller; the solar power charge controller is connected with the storage battery; and the storage battery is connected with the machine integrated charge-reverse UPS; The power supply input interface is connected with the integrated UPS charge-reverse machine.

These solutions, in light of the information available, present as their main drawback their complexity and high cost, the contact surfaces between the cooking medium and the heat generation medium are generally flat, there is also the element of energy transfer between types of different currents (CC-AC), and this makes them inefficient since part of the heat generated is lost and is not used in cooking. Additionally, they are limited to the cooking process and do not allow them to be used for other household functions such as for example to power, through the same stove, other household appliances that require electrical energy for their operation or to illuminate rooms, rooms or to Recharge electronic devices, such as cellular devices, laptops, cordless tools, among others.

DETAILED DESCRIPTION OF THE INVENTION. Next, the details of the present invention will be described, together with the illustrations offered through the drawings for a greater understanding of it. However, an average person skilled in the art will understand that the object of the present invention can be adapted and modified as appropriate to the application in which it will be used, and therefore can be used in other applications; However, such additions, modifications and applications do not depart from the scope of this invention.

Figures 1 and 2 show the system for cooking food that is the object of the present invention and the modules that compose it, and within these the intelligent multifunctional stove 700, which comprises a perimeter casing 100, substantially rectangular, although it could adopt other shapes. equally valid and functional configurations, which defines a central cavity 101 delimited by the sides that make up the perimeter casing 100. The perimeter casing 100 comprises, throughout its interior perimeter, a gasket of a thermal insulating material 217 intended to protect the electronic components and the user of the stove from the heat and possible burns generated by the temperature that occurs during the cooking process. In addition, this gasket made of thermal insulating material 217 contributes to concentrating and reorienting the temperature, making the cooking process more efficient. The intelligent multifunctional stove 700 also includes a lower cover 102, which is joined by mechanical means to the lower part of the perimeter casing 100, serving as a base for the intelligent multifunctional stove 700, and an upper cover 105, which in its central part comprises circular openings. 107 centered and independent of each other. Heating means made up of lower thermal bases 103a and 103b are fixed on the lower cover 102, generally made of a refractory material in the shape of a hollow truncated cone, although it can take other convenient shapes, intended to conveniently receive and house heat generating means, made up of bases preferably of a refractory material 104a and 104b with a thermal capacity greater than 3000 degrees Celsius, for example a ceramic material, arranged to house resistances 216a and 216b as heat generating elements, which can reach temperatures greater than 500 degrees Celsius and which, when energized, produce the conversion of electrical energy into the heat energy necessary for the cooking process. The circular openings 107 are arranged to be positioned on the lower thermal bases 103a and 103b that house inside the refractory material bases 104a and 104b where the resistances 216a and 216b are placed, in the circular openings.

107, the cauldrons or pots 108 are placed which, when they come into contact with the heat produced by the resistances 216a and 216b, allow the food to be cooked.

At the edges that define each circular opening 107, the stove 700 includes thermal adjustment rings 109, which provides an airtight seal when the cauldron or pot 108 is positioned inside the circular openings 107, preventing the heat generated by the resistances from escaping. 216a and 216b between the outer wall of the cauldrons or pots

108 and the inner edge of the circular openings 107, in this way efficient use of the energy produced in cooking the food is achieved by not allowing escape or thermal exchange with the outside, concentrating all the energy on cooking or heating the food. contents of the cauldron or pot 108.

Additionally, the thermal adjustment rings 109 provide a stop or seat for the lids 111 of the cauldrons or pots 108, and a height is established between the upper lid 105 and the refractory material bases 104a and 104b that allows the cauldrons or pots to be placed. 108 so that they are in direct contact with the resistance protectors 7a and 7b that protect the refractory material 104a and 104b where the resistances 216a and 216b are housed from possible blows or impacts derived from the use and placement of the cauldrons on them. or pots 108. Additionally, the resistance protectors 7a and 7b contribute to concentrating and transferring the heat generated by the resistance 216a and 216b towards the bottom of the cauldrons or pots 108, making the use of the energy used in the generation more efficient. of heat.

Likewise, on the upper cover 105 and joined to it by the hinges 110, there are the thermal upper covers 111, preferably made of a tempered and transparent material, which allow the user to have physical and visual access to the cauldrons or pots 108. and they prevent the heat that is transferred to the contents of the cauldron or pot 108 during the food cooking process from escaping into the atmosphere, making an efficient cooking process possible and guaranteeing greater use of energy. The thermal upper lid 111 can take various shapes, however, a preferred example of the present invention takes the form of a dome that describes an interior cavity where the steam derived from cooking is concentrated and contributes to making the cooking process more efficient. The thermal upper covers 111 are activated by a handle 112 or by means of the grip button 113 arranged for such purposes, hence when one of the thermal upper covers 111 is lifted it moves backwards by the operation of the hinge 110, leaving the cauldron or pot 108 in its open position and allowing access to its interior.

The upper cover 105 also comprises a trim 106 in a perpendicular relationship with the upper cover 105 and that covers the entire length of the rear part of the perimeter casing 100, serving as a backrest or stop and preventing utensils placed on the cover from falling. 700 smart multifunctional stove.

The intelligent multifunctional stove 700 further comprises a central control module 200 conveniently positioned inside the perimeter casing 100, generally, but not limited, in the space defined between the two lower thermal bases 103, as shown in the Figure 2.

The central control module 200 is shown in greater detail in Figure 3 and comprises a housing 200a, substantially rectangular with a base 200b and sides 200c, and a module cover 201 and comprises inside a programmable motherboard 202, for example a mother board of the type MoBoStamp-pe BS2pe Motherboard (#28300) although other types may also be usable. Two DC voltage controllers 203 and 204 are connected to the programmable mother board 202, with the capacity to handle up to 1500 watts and 110 volts each, which allow controlling and regulating the power consumption of the resistors 216a and 216b in non-variable values. greater than 200 watts/h, without compromising the cooking option selected by the user, guaranteeing optimal operation of the smart stove 700. Each controller 203 and 204 connects to two potentiometers 205 and 205a and 206 and 206a, two of those controllers 205 and 206 regulate the power delivered to each resistor 216a and 216b by calibrating the current output and the other two potentiometers 205a and 206a are activated by the user when he activates 203 and 204 to start the cooking process, thus regulating the temperature that It is generated in the cooking process and making energy consumption more efficient.

A bank of relays 18 is connected to the programmed motherboard 202 that activates the controllers 203 and 204, the fans 303 and 304 and the chargers 301 and 302.

Temperature sensors 207 and 208 constantly measure the working temperature inside the smart multifunctional stove 700 and compare it with the reference working temperature that has been defined to prevent the housing 100 from overheating or the components of the central control module 200 from being damaged due to excess temperature, in the presence of high temperatures detected by the temperature sensor 207, the power-on is ordered. of the cooling fans 8 and 9, which are connected to the relay bank 18, extracting heat to the outside and reducing the interior temperature of the intelligent multifunctional stove 700, protecting the electrical components of the central control module 200.

The controller buttons 209 and 210 that are activated by the user are connected to the programmed mother board 202 to activate the controllers 203 and 204 that allow the resistors 216a and 216b to be activated and put into operation independently and according to requirements.

Push buttons 31 and 32 are connected to the programmable mother board 202 to select, by pressing, the desired package, module or cooking options that are presented on the LED display 213 as a flow menu of options. Push buttons 31 and 32 have an integrated LED that flashes intermittently when the 700 Smart Multifunctional Stove is in operation.

The intelligent multifunctional stove 700 has at least one USB port 212 through which an operating software that includes the working parameters of the intelligent multifunctional stove 700 is introduced to the programmed mother board 202 and also allows the connection of different types of peripherals. such as chargers, memories, communications modem, among others. All information and operating parameters of the intelligent multifunctional stove 700 are shown to the user through the LED screen 213, which provides an interface that shows the working status of the intelligent multifunctional stove 700.

A system reset button 214 is also connected to the programmed mother board 202 which, as its name indicates, when activated in emergencies or malfunctions, disconnects the entire system and stops the operation of the intelligent multifunctional stove 700.

The power supply module of the intelligent multifunctional stove 700, shown in Figure 4, comprises a power inverter/converter 300 that powers the programmable mother board 202 through cables 15. Connected to the power inverter/converter 300 are the chargers 301 and 302, with their respective cooling fans 303 and 304 that are activated by the controlled temperature sensor 208 by the heat sensor 17 relay for cooling, of the chargers 301 and 302 when the working temperature exceeds the defined working parameter, and where the chargers 301 and 302 are connected through connectors 305 and 306 to a medium energy storage, for example battery bank 500, made up of at least one battery, preferably gelatin, lithium, lead or similar, which is powered by an external energy source, preferably a renewable source 600 of the wind or solar type, although it can eventually be powered by a conventional energy network.

The power supply system also comprises the switch 39 that defines the ON/OFF states of the energy inverter/converter 300 and where the energy inverter/converter 300 is connected to a controller for renewable energy source 600, which serves as an inference. between the renewable energy source 600, for example a solar panel, and the energy inverter/converter 300, or failing that a wind turbine or the like, not illustrated, but which are obvious to the expert with average knowledge.

From the power inverter/converter 300, the connector cable 15 comes out that powers the programmable motherboard 202 and the components that are connected to it, and the cables 25 and 26 come out that power the chargers 301 and 302 and the chargers 301 and 302. connectors 23 and 24 come out to batteries 500.

The intelligent multifunctional stove 700 provides a supply of energy that is stored in its 500 batteries and that can be used for purposes other than cooking food. In this way, a conventional electrical outlet (not shown) can be connected to the power inverter/converter 300 to plug in any other household appliance, such as a radio, blender, television, or other similar devices to receive power from the intelligent multifunctional stove 700. Likewise, a network of lights or lamps can be connected, for example, LED lamps or low consumption lamps and illuminate rooms or rooms of a house through the intelligent multifunctional stove 700 or provide charging to devices that can receive said charge via the USB 212 port.

As can be derived from what has been explained so far, the intelligent multifunctional stove 700 operates with the energy that is directly generated by the renewable energy source 600. After the energy is transformed by the energy inverter/converter 300, it powers the stove and the Surplus energy is stored in batteries 500 which They make up the energy storage medium. In this way, the intelligent multifunctional stove 700 can make use of the energy at the time it is generated or the energy accumulated in the batteries 500 of the energy storage medium when generation is not possible, for example, at night for the assuming the power source is a solar panel, as illustrated in Figure 4.

The diagram of the flows and processes that define the operation of the intelligent multifunctional stove 700 is illustrated in Figure 5 where it is shown that the operation of the intelligent multifunctional stove 700 begins when the user presses the push button 32 and the stove receives energy coming from the batteries 500 or the control panel 400 that manages the renewable energy source. Once the intelligent multifunctional stove 700 is turned on, the screen or monitor 213 is turned on to show the user the status of the stove and its peripherals as the system performs and completes a review of its connected components and peripherals. Immediately afterwards, a voltage and amperage sensor is initialized so that the system can survey the status of the batteries 500 and initialize the system through the Inverter 300 and determine whether to send or charge the batteries 500 for the operation of the resistors. thermals 216a and 216b through controllers 203 and 204; while bypassing the charging system to stove only or vice versa, following predefined instructions and work codes.

Next, the system verifies that the thermal resistors 216a and 216b are in off mode and reads the state of the push button 32 for the operation of the thermal resistors 216a and 216b, and determines whether or not the button has been pressed. If push button 32 has been pressed the flow continues to the next process; On the other hand, if the push button 32 has not been pressed, its status is checked again by sending the program flow to the reading process of the push button 32.

The intelligent multifunctional stove 700 comprises 5 packages, modules or cooking options (stove state 1 to stove state 5), programmable and mutually exclusive that operate independently for each thermal resistance 216a and 216b, these cooking modules are shown to the user of the stove 700 as an options menu; By pressing the push button 32 by the user, a signal is generated that indicates the selection of a cooking option and the new state of the stove 700 is defined, assigning a cooking time that can be 5 minutes, 10 minutes. , 30 minutes, 1 hour and 2 hours, being defined and assigned, for the module selected, a preset cooking time that is executed in accordance with the option selected by the user.

The option chosen by pressing the Push button 32 is assigned to a resistance that is defined as turned on when receiving electrical energy, activated by one of the controllers 203 and 204, which is converted into heat energy, starting the cooking process that can be verified by the flashing of the integrated LED Push button 32.

The entire cooking process including the remaining cooking time according to the selected cooking package or option, as well as the status of all operating indicators of the smart stove 700, such as battery voltage or status, charging process of batteries, connected peripherals, status of the communications module with the Wi-Fi connection indicator, software updates in progress or pending installation, data transmission to the 800 communications module, temperatures inside the stove, are displayed on the screen or monitor of status 203 that the smart stove 700 has.

During the run time of the selected package or cooking option the voltage/amperage sensor 35 is maintained taking check readings from the batteries 500 that make up the energy storage medium, to determine the level of energy available, the charging condition present in the batteries 500 and the demand required for its operation by the smart stove 700 and the peripherals that it may have connected in parallel to the cooking process being executed. In this way, if the voltage/amperage sensor 35 detects that the charge of the batteries 500 is less than 15 volts, it activates the charging relay located in the relay bank 18 to begin reestablishing the optimal energy levels in the batteries. 500 that make up the energy storage medium and at the same time sends a lowvoltage message to the screen or status monitor 203. The battery charging relay 500 will be activated and the batteries 500 will be receiving charge until the energy levels are back within the optimal working parameter (15 volts). Once the aforementioned charge level is reached, the charge relay is deactivated and the lowvoltage message disappears from the screen or status monitor 203. On the contrary, if the Voltage/Amperage sensor 35 determines that the battery charge 500 is greater than 15 volts, the load relay is deactivated and the message overvoltage is indicated on the screen or status monitor 203, continuing the supply of energy to the cooking process and to the peripherals that could be connected demanding energy from the 700 intelligent multifunctional stove.

The intelligent multifunctional stove 700 is designed to function optimally, guaranteeing a complete cooking process with the lowest possible energy consumption, which is why after the first 5 minutes have elapsed, from the moment it was turned on, it takes a census of the temperature reached by the thermal resistances 216a and 216b during preheating, in order to reach the optimal working point and heat through the controllers 203 and 204. After the preheating of the thermal resistances 216a and 216b has elapsed, if the voltage in the batteries is greater than 15 volts, the load relay remains deactivated and the stove 700 will remain on and will enter the efficiency mode or state where the thermal resistances 216a and 216b will continue to receive energy via sensors and codes, for periods of 5 minutes, at a time. that a constant census of the charge levels in the 500 batteries is maintained, after 5 minutes or the temperatures required for cooking have been reached, the stove relay is deactivated and begins a 7-second pause with temperature control cooking. This is possible because after each period of 5 minutes of heating the thermal resistances 216a and 216b in which the specific and optimal heat levels for the type of cooking selected are reached, it is alternating periods of 7 seconds either because activates or deactivates the stove relay as necessary and according to the programmed or censused time intervals to maintain the work of the controllers 203 and 204 according to the indicated programming.

The thermal resistors 216a and 216b will turn on if they have been off for 5 seconds or more. The system constantly checks the status of the lid 111 of the pot or cauldron, if the lid 111 is open, an alert is issued in the form of a sound indicating such a situation to the user and the status of the Push button 32 is verified, if the button If Push 32 has been pressed, the thermal resistances 216a and 216b of the intelligent multifunctional stove 700 will be turned off and the Push 32 LED will turn off, which has been flashing indicating that the stove 700 was in use, verifying whether the cooking time has been completed or not in accordance with the cooking option that was initially selected by the user. In the event that the user has pressed the Push button 32 while the intelligent multifunctional stove 700 is executing a work instruction, the resistance relay and the multifunctional stove will turn off. smart 700 adopts the shutdown state, returning the system to the initial verification state of the Push button 32, however, if the Push button 32 button has not been pressed, the system displays the status of the intelligent multifunctional stove on screen 213 700 and the elapsed cooking time and will continue executing the instructions described above.

Figure 5 shows the connection of the communications module 800 to the intelligent multifunctional stove 700. The communication module 800 allows the connection of the intelligent multifunctional stove 700 to the central server 900. The communications module 800 comprises a conventional modem that connects via a wired connection or through a card with a Wi-F adapter that can be connected to the USB port 212 or directly to the motherboard 202 obtaining access to the Internet and the central server 900, which comprises a server that manages a database that is It is responsible for storing and processing all the usage data of the 700 stove and its operating parameters, as well as the information regarding the use and consumption of the energy that has been supplied. Likewise, once the intelligent multifunctional stove 700 is connected to the Internet through the aforementioned means, it can download the operating software updates from the central server 900 and allow access via an app to the user for remote management of the stove, including the possibility of programming different food cooking, in accordance with any of the 5 cooking packages available, starting or ending cooking processes, giving power supply or cutting the power supply to a peripheral connected to the smart multifunctional stove 700, review the energy status in the 500 batteries, among other operations that can be carried out with the smart multifunctional stove 700 through the app.
