Description

Technical Field

[0001] The present invention relates to the technical field of cooking applications, in particular to a blackbody balanced stove with both cooking and freezing and fresh-keeping functions. Background Art

[0002] Throughout the long history of human development, the advent of fire was epoch-making, significantly accelerating humanity's transition into civilized society. Every advancement in cooking and heating technology has profoundly impacted human life. With the development of empirical science, which studies the microscopic world, cooking and heating technologies, primarily microwaves, electromagnetic waves, and light waves, have emerged. While these new technologies have brought convenience to humanity, they have also brought numerous negative impacts, a necessary consequence of the limitations of Western empirical science, which studies the microscopic world. Traditional kitchen cooking and heating technologies, such as open flames, electromagnetic heating, microwaves, and light waves, have failed to effectively address a range of issues, including fume, energy consumption, fire safety, food moisture and nutrient loss, and odor and toxins. The haphazard nature and complexity of Chinese cuisine preparation are particularly prominent, and have long been a bottleneck in its production.

[0003] Existing technologies such as microwave ovens, light wave ovens, rice cookers, induction cookers, air fryers, cooking machines, etc. are essentially different from the heating technology in the present invention. The former all belong to traditional open thermodynamic systems.

[0004] A common characteristic of open thermal systems is the inability to achieve energy balance within the cooking cavity, nor to increase entropy. This leads to unstable heating, resulting in water and nutrient loss, explosions and fires, fumes, the generation of carcinogens, complex operation, and a lack of precise control. For example, microwave ovens use industrial microwaves to generate heat through the vibration and friction of water molecules in food. This heats the food internally, leading to significant water loss and the risk of eggs exploding. Furthermore, electromagnetic waves are highly sensitive to metal materials and emit certain harmful radiation to the environment and humans. Lightwave ovens, which essentially operate in the infrared spectrum, reach temperatures exceeding 300°C, making them less safe and energy-intensive. This leads to a rapid loss of water and nutrients in food, and also to the risk of burning. Induction cookers utilize industrial electromagnetic waves to radiate heat from a metal pot, which then absorbs these waves and generates heat. However, their disadvantages are high temperatures, which can be harmful to humans and the environment. They also generate significant amounts of fumes and steam during cooking. These cooking methods present a high risk of combustion, making them highly unsafe and prone to burning food, which can lead to the generation of carcinogens. Air fryers heat food using hot air generated by electric heating. However, they suffer from rapid loss of moisture and nutrients, high energy consumption, and the constant release of heat into the air, significantly limiting their cooking range. Stir-fryers, on the other hand, use traditional electric heating. Aside from the added cooking action and precise temperature control, they're essentially the same as traditional stir-fryers, still producing fumes and currently only capable of heating, not freezing and preserving food.

[0005] The present invention, however, uses the extreme thermodynamic model of the universe derived from theoretical physicists through theoretical deduction and calculations in classical thermodynamics. Therefore, the two are completely different, and the results obtained when applied to heating in cooking are also completely different. Through theoretical research and analysis, the author innovatively applies the large-scale model of "isolated blackbody equilibrium thermodynamics" to the field of kitchen cooking. All currently known traditional cooking heating systems, according to the "Thermodynamic System," are classified as "open thermodynamic systems." A common drawback of these heating systems is that internal energy cannot be balanced. Heating food in open systems results in unstable and precise heating, rapid exchange of heat energy with the outside world, resulting in smoke and carbon emissions, large amounts of steam, uneven heating, and the inability to accurately control temperature. This can easily cause ingredients such as eggs and fish to burst, burn, and emit carcinogens, leading to loss of water and nutrients in the ingredients, high energy consumption, increased cooking complexity, and electromagnetic radiation. Traditional heating methods also pose the problem of food being highly susceptible to secondary contamination by the environment.

[0006] The new technology uses the principle of blackbody thermal radiation to restructure the equilibrium cooking cavity, and combines multidisciplinary collaborative toxin degradation mechanisms and environmental design elements. Environmental protection, energy saving and safety are mainly reflected in the sustainability of energy utilization. By optimizing the cavity structure, the thermal radiation energy is maximized and energy loss is reduced. At the same time, the system design takes into account the impact of ambient temperature on the cooking process to ensure stable performance under different environmental conditions. By setting up a liquid nitrogen cylinder connected to the interior, nitrogen is quickly released into the cavity. During the rapid expansion process, nitrogen quickly absorbs the energy temperature of the food. When constant temperature preservation is required, the control program will use the temperature sensor to accurately control the amount of nitrogen released, thereby maintaining the temperature in the cavity within the set range. Summary of the Invention

[0017] The present invention provides a black body balanced stove that combines cooking and freezing functions. Compared with the existing technology, it has the following advantages: 1. This blackbody balanced cooker, which features both cooking and freezing preservation, uses a photocatalytic module to catalyze food and produce active substances. It also inhibits or kills harmful microorganisms, reducing nutrient loss while also altering the structure of food ingredients, making them more easily absorbed by the body and thus improving bioavailability. The Pd reduction catalyst employed by the cooker uses surface functional groups to adsorb some volatile pollutants within the cavity and promote electron transfer, participating in electrochemical reduction. It also effectively collaborates with the ultrasonic piezoelectric module to enhance reduction efficiency, thereby addressing a range of issues, including oil smoke, energy consumption, fire safety, food moisture and nutrient loss, and odor and toxins.

[0018] 2. This Blackbody Balanced Cooker, which combines cooking and freezing functions, activates a solenoid valve via the main control circuit board, rapidly releasing nitrogen from a miniature liquid nitrogen cylinder through an inlet pipe into the cavity of the graphite liner. During its rapid expansion, the nitrogen rapidly absorbs the energy and temperature of the food and exits the cavity through the outlet pipe, also known as the Tesla valve pipe. When constant temperature preservation is required, the control program precisely controls the amount of nitrogen released through the temperature sensor, maintaining the temperature within the cavity within the set range and achieving the freezing and preservation function.

[0021] The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] See also Figure 1-2 The embodiment of the present invention provides a technical solution: a blackbody balanced stove with both cooking and freezing preservation functions, comprising a lower shell 1 and an upper cover outer shell 2, the inner cavity of the lower shell 1 is provided with a graphite liner 8, the lower surface of the graphite liner 8 is provided with a lower thermal insulation cover 9, the bottom of the upper cover outer shell 2 is respectively provided with a photocatalytic module 6 and an ultraviolet light source 21, and an ultrasonic piezoelectric module 7 is provided on the outside of the graphite liner 8, the bottom of the inner cavity of the lower shell 1 is provided with a heat insulation board 10, and the top of the heat insulation board 10 is fixedly installed with a heating plate 11, and the bottom of the lower shell 1 is provided with an upper thermal insulation cover 4.

[0023] The photocatalytic module 6 is an ultrasonic generator, wherein the ultrasonic piezoelectric module 7 is mounted on the outside of the graphite liner 8. The ultrasonic piezoelectric module 7 is made of a composite material consisting of a lead-free piezoelectric ceramic (barium titanate BaTio3, preferably potassium sodium niobate KNN, with a Curie temperature >300°C, considering the Curie temperature requirement of >120°C), a photocatalyst (Tio²), a reduction catalyst Pd particles, and the like. The ultrasonic generator is connected to the piezoelectric ceramic, and two high-frequency circuits are provided on the electronic control, connected to the piezoelectric ceramic sheet. Ultrasonic waves are generated by resonance generated by high-frequency conversion, and the piezoelectric ceramic forms a piezoelectric effect under stress. The graphite liner 8 is made of high-purity graphite all-carbon molecular carbon material, that is, a black body. A temperature sensor is installed on the inner wall of the graphite liner 8, and the inner wall of the graphite liner 8 and the lower shell 1 are coated with a functional piezoelectric functional coating, namely KNN piezoelectric ceramic coating material. The bottom material of the container is a porous natural material (tourmaline) with adsorption and piezoelectric properties, which further enhances the strength of reducing heavy metal ions.

[0024] The graphite liner 8 must be made of a black body or a gray body similar to a black body material to achieve equilibrium, regardless of the material. In this solution, the black body and the gray body of the black body similar to the black body material are interpreted as the definition and scope in physics.

[0025] The cavity is composed of a black body in equilibrium. Utilizing the principle that a black body absorbs electromagnetic waves but does not reflect them, it uniformly emits electromagnetic waves of the same frequency after absorbing energy, thus maintaining a near-absolute equilibrium energy state within the cooking cavity. For more information, please consult the relevant theory and data in the physics book "Blackbody Thermal Radiation Principle."

[0026] The reason for choosing materials in this direction is that the ratio of energy absorption and heat radiation is 1 to 1. In this case, an isolated cavity in equilibrium can be achieved in the architecture.

[0027] The setting of the photocatalytic module 6 in this solution is a brand-new innovation in the field of cooking and heating. Changes in formula and materials still do not affect our claim to this claim.

[0028] Ultrasonic piezoelectric module 7 is used for the first time in the field of cooking heating. The change of materials under the same principle does not affect our claim for protection of this right.

[0029] Function and principle of photocatalytic piezoelectric module.

[0030] Part 1: Principle: When the device heats, the piezoelectric material resonates under the influence of ultrasound, generating mechanical stress and surface charge. This creates a local electric field that drives electrons to rapidly transfer through the graphite body into the cooking cavity, generating a potential difference. Because the graphite inner liner 8 used in this solution is highly conductive, the transferred electrons quickly pass through the graphite container, reducing trace heavy metal ions such as Pb²⁺, Cd²⁺, and Hg²⁺ in the soup and ingredients to low-valent or elemental states, thereby reducing the harmful effects of heavy metal ions on the human body.

[0031] The reaction logic is as follows: Pb²⁺ + 2e - piezoelectric catalysis - Pb². In this module combination, the TiO² primarily functions as a photocatalyst. The principle behind photocatalytically increasing the nutritional value of food primarily involves the production of active substances by the photocatalyst under light exposure. These substances promote the conversion or generation of nutrients in food. The basic principle is as follows: Since the main cooking element (graphite inner pot 8) in this device is made of graphite, a blackbody material, the entire heating and cooking process occurs within a sealed cavity via thermal radiation waves generated by the carbon molecules. The thermal radiation waves emitted by the graphite body fall within the photon energy spectrum. When the device is heated, the TiO² absorbs photons and generates hole pairs. Because electrons have reducing properties, both can participate in redox reactions. The electron holes generated by the photocatalyst react with water and oxygen in the cavity to produce active substances such as hydroxyl radicals (OH) and superoxide radicals (O²⁻), which have strong oxidizing or reducing abilities. These active substances can promote the conversion of certain components in food. For example, in vitamin synthesis, light exposure may promote the synthesis of vitamin D. Generation of antioxidants: Active substances promote the generation of antioxidants such as polyphenols. Protein and fat decomposition: Active substances can break down large molecular proteins and fats into smaller molecules that are more easily absorbed. The active substances produced by microbial inhibition of photocatalysis can also inhibit or kill harmful microorganisms, reduce nutritional losses, and extend the shelf life of food. Improving bioavailability Photocatalytic reactions may change the structure of food ingredients, making them easier to be absorbed by the human body, thereby improving bioavailability. Photocatalysis promotes the conversion or generation of nutrients by generating active substances, thereby increasing the nutritional value of food and having the effect of inhibiting microorganisms. The role of the reduction catalyst Pd particles is to adsorb some volatile pollutants in the cavity through surface functional groups (such as carboxyl and hydroxyl groups) and promote electron transfer, participate in electrochemical reduction, and effectively cooperate with the ultrasonic piezoelectric module 7 to enhance the reduction efficiency.

[0032] Structural Description Describing the device from the inside out, the cooking graphite inner pot 8 is the core component of the device, made of high-purity graphite, a pure carbon molecular material. Within the graphite body or on the inside of the upper cover, space is reserved for embedding a photocatalytic module 6 and an ultrasonic piezoelectric module 7 (position changes do not affect functionality). The inner wall of the cavity is coated with a functional (blackbody or graybody) piezoelectric coating. The photocatalytic module is equipped with a UV light source. The photocatalytic module 6 absorbs ultraviolet light from the UV light source 21 to produce a catalytic effect.

[0033] The lower insulation cover 9 encases the graphite liner 8. The lower insulation cover 9 and the upper insulation cover 4 are constructed from a double-layer sheet metal composite, both coated with a nano-insulation coating. A space is left between the two layers of sheet metal, filled with insulation material. This material is a nano-aerogel powder (silicon dioxide) synthesized by adding 5%-10% sodium silicate liquid to the powder to ensure its stability, acting as a binder and stabilizer. The sodium silicate reacts rapidly to form a stable silica gel network while avoiding damage to the aerogel's nanoporous structure. The bottom of the lower insulation cover 9 has threading holes filled with high-temperature-resistant silicone and other high-temperature-resistant gaskets.

[0034] An insulation board 10 is provided at the bottom of the inner cavity of the lower shell 1, and a heating plate 11 is fixedly installed on the top of the insulation board 10. The heating plate 11 is in contact with the bottom of the graphite liner 8. A heating plate 11 is installed at the bottom between the lower insulation cover 9 and the graphite liner 8. The insulation board 10 is provided under the heating plate 11, which is a high-temperature resistant inorganic insulation material. A temperature sensor is provided on the graphite liner 8. The temperature sensor circuit is connected to the external main control circuit board 13 through the lower insulation cover 9. The power cord of the heating plate 11 is composed of a high-temperature resistant conductive wire and is connected to the external main control circuit board 13 through the wire hole of the lower insulation cover 9. There is an automatic circuit breaker on the power line, and the safety regulations require automatic power-off at 230 degrees. The heating plate 11 is made of a composite of a microcrystalline glass panel and a graphene material.

[0035] Special note: 1. Energy-saving principle of this solution: Since the heating is carried out inside the insulated stove, the energy is confined to the black body material and evenly exchanges energy with the food. Except for the energy consumed by preheating during startup, the entire cooking process enters a constant temperature state when the set value is reached. In this state, cooking will continue but no energy will be consumed, just like the principle of a refrigerator.

[0036] 2. No smoke or emissions are generated; this is because the entire cooking and heating process is completed in a closed cavity. The cavity is in a state of near absolute equilibrium, and the internal energy is stable, so no smoke or large amounts of steam are generated.

[0037] The lower shell 1 is wrapped around the outside of the lower insulation cover 9 and is made of molded sheet metal or plastic. A certain distance is left between the lower insulation cover 9 and a layer of high-temperature resistant silicone buffer is sandwiched between the lower insulation cover 9 and the graphite liner 8.

[0038] The inner layer of the upper cover outer shell 2 is made of graphite full carbon molecular material and is treated with a non-insulating coating inside. A position for embedding the photocatalytic module 6 is reserved on the outer wall, and the position of the embedded recessed inner wall is not coated. The outside of the upper cover is wrapped with an upper thermal insulation cover 4, and a high-temperature resistant silicone material is used for buffering. The outside of the upper thermal insulation cover 4 is provided with a sheet metal or plastic molded shell.

[0039] The lower shell 1 and the upper cover outer shell 2 are rotatably connected via a buffer hinge 12. The cover is opened in an upward flipping manner, and a buffer damping device is provided at the connection position.

[0040] A control touch screen 3 is installed on the upper portion of the upper cover outer shell 2 , and the touch screen 3 is connected to the integrated circuit main control circuit board 13 via data and power lines.

[0041] A main control circuit board 13 is provided on the surface of the lower shell 1, and a power socket 14 is provided below the main control circuit board 13 and at the corner of the lower shell 1. The touch screen 3, the power socket 14 and the solenoid valve 18 are electrically connected to the main control circuit board 13 through wires. The main control circuit board 13 consists of: a circuit board, a display screen, a temperature sensor (set on the inner wall of the graphite liner 8), a circuit breaker, a software part; a control program and an algorithm.

[0042] Standard container materials include paper and aluminum foil composite containers, graphite or ceramic containers, glass containers, metal, non-metallic inorganic containers, containers with piezoelectric ceramic coatings, and other heat-resistant and non-toxic materials. Containers can all become supporting utensils and anti-scalding clamps for this cooking device.

[0043] This device is different from the traditional cooking process and packaging process Traditional style: ingredients---put into pot--cook and heat--pack--eat This device: food materials---prepare----package----put into the equipment together with the packaging----heat----take out and deliver or open the packaging for consumption.

[0044] The advantage is that the process is safe and no environmental pollution is generated during the packaging process. At the same time, the finished product and packaging are equivalent to irradiation sterilization, meeting industrial standards.

[0045] A bottle barrel 20 is fixedly installed on the side of the lower shell 1, and the top of the bottle barrel 20 is rotatably connected to the outer cover 15, and the inner cavity and inner wall of the bottle barrel 20 are respectively provided with a miniature liquid nitrogen cylinder 17 and a rubber pad 16, and the rubber pad 16 fits with the miniature liquid nitrogen cylinder 17, wherein the rubber pad 16 has elasticity, so the miniature liquid nitrogen cylinder 17 is clamped, and the miniature liquid nitrogen cylinder 17 is pluggable. The output end of the miniature liquid nitrogen cylinder 17 is installed with a solenoid valve 18, and the input end of the solenoid valve 18 is installed with an air intake pipe 19, and the air intake pipe 19 passes through the inner cavity of the lower shell 1 and is communicated with the upper and lower inner cavities of the graphite liner 8. An air outlet pipe 5 is provided on the surface of the lower shell 1, and the air outlet pipe 5 is communicated with the graphite liner 8. The bottle barrel 20 is installed outside the lower shell 1 of the cooking stove, and is passed through The rubber pad 16 in the bottle tube 20 can be plugged in and out of the miniature liquid nitrogen cylinder 17. There is a gas intake pipe 19 on the miniature liquid nitrogen cylinder 17 that passes through the cavity of the graphite liner 8. There is a gas solenoid valve 18 at the connection point. The solenoid valve 18 is connected to the main control circuit board 13. When the cavity of the cooking graphite liner 8 is not heated, its structure itself actually meets the requirements of the freezing and heat preservation environment. When the food needs to be frozen, just put the food into the cavity of the cooking graphite liner 8. The main control circuit board 13 starts the device to open the solenoid valve 18 and quickly release the nitrogen in the miniature liquid nitrogen cylinder 17 into the cavity of the graphite liner 8 through the intake pipe 19. During the rapid expansion process, the nitrogen quickly absorbs the energy and temperature in the food and is taken out of the cavity through the outlet pipe 5, that is, the Tesla valve pipe. When constant temperature preservation is required, the control program will accurately control the release amount of nitrogen through the cooperation of the temperature sensor, so as to keep the temperature in the cavity within the set range. In addition, when the miniature liquid nitrogen cylinder 17 is used up, the miniature liquid nitrogen cylinder 17 and the solenoid valve 18 are removed and replaced with a new miniature liquid nitrogen cylinder 17 and connected to the solenoid valve 18.

[0046] This design is in contrast to traditional refrigerators; traditional refrigerators have single functions, complex structures, high costs, and are not suitable for outdoor use.

[0047] This solution utilizes the isolated constant temperature balance cavity of the cooking stove and creatively introduces physical refrigeration, thus solving the problem of preserving and freezing food in the wild.

[0048] During operation, the upper cover outer shell 2 is rotated and opened through the buffer hinge 12, the object is placed in the inner cavity of the graphite liner 8 and then closed, and then the heating plate 11 is started through the main control circuit board 13 to heat the graphite liner 8. During the heating process, the photocatalytic and ultrasonic piezoelectric modules 6 will be started to produce a piezoelectric effect and generate active substances. These substances have strong oxidation or reduction capabilities. The active substances can promote the conversion of certain components in food, thereby solving a series of problems such as oil fume problems, energy consumption problems, fire safety problems, food moisture and nutrient loss problems, odor toxins, etc.

[0049] In addition, when freezing and preservation are required, the heating of the heating plate 11 is stopped, and the device can be started by the main control circuit board 13 to open the solenoid valve 18 to quickly release the nitrogen in the miniature liquid nitrogen cylinder 17 into the cavity of the graphite liner 8 through the air inlet pipe 19. During the rapid expansion process, the nitrogen quickly absorbs the energy and temperature in the food, and brings the temperature out of the cavity through the air outlet pipe 5, that is, the Tesla valve pipe, so that the food is cooled and the freezing and preservation function is achieved.
