An embodiment of the present application provides a cooking apparatus, as shown in fig. 1A, the apparatus includes: shell 110, insulating food tray 120, electrode subassembly 130 and power control subassembly 140, wherein:

the insulating food tray 120 is arranged in the shell 110 and used for containing food materials 200;

here, the insulating food material tray may be made of any suitable high temperature resistant insulating material, including but not limited to glass, ceramic, etc.

The electrode assembly 130 is disposed in the insulating food tray 120, and the distances between corresponding points on the two electrodes are the same;

the electrode assembly 130 is used for applying an electric field to the food materials after being electrified, so that current passes through the food materials to generate heat energy to heat the food materials;

here, the electrode assembly is disposed in the material tray, and is insulated from the electrode assembly when the material is not loaded in the material tray. When food materials are put in the food material tray, the two electrodes are respectively in direct contact with the food materials, and when the two electrodes are electrified, the two electrodes apply an electric field to the food materials. Because the food material generally has a certain conductive characteristic, under the action of an electric field, current can be generated in the food material, and through the impedance of the food material, the food material can generate heat energy under the action of the current flowing through the interior of the food material, so that the food material is heated. At the moment, because the distances between the corresponding points on the two electrodes are the same, the potential difference between any corresponding points on the two electrodes can be equal when the electrodes are electrified, so that the currents generated in all areas between the two electrodes are the same when the two electrodes of the electrodes are fully contacted with food materials after the electrodes are electrified, and the uniform heating is promoted. In practice, the electrode assembly may be, but is not limited to, a stainless steel electrode or a novel electrode material (such as an electrode of titanium, platinum, etc.), and those skilled in the art can select a suitable electrode according to practical situations in practice, which is not limited in the embodiments of the present application.

The electrode assembly may be arranged in the food tray in any suitable way, such that the distances between corresponding points on the two electrodes are the same. In some embodiments, as shown in fig. 1A, the food tray 120 is horizontally disposed, the two electrodes of the electrode assembly 130 are respectively horizontally disposed in the food tray 120, and the two electrodes are parallel to each other, so that the vertical distances between any two points on the two electrodes are the same. In other embodiments, as shown in fig. 1B, the food tray 120 is horizontally disposed, the electrode assembly 130 is vertically disposed in the food tray 120, and the two electrodes are parallel to each other in the vertical direction, so that the horizontal distance between any two points on the two electrodes is the same.

The power control component 140 is configured to: acquiring a real-time electric signal of the electrode assembly; determining power supply parameters according to the real-time electric signals, so that when power is supplied to the electrode assembly according to the power supply parameters, the real-time electric signals of the electrode assembly meet specific conditions; and supplying power to the electrode assembly according to the power supply parameter.

Here, the power control unit is connected to both poles of the electrode assembly to provide the electrode assembly with necessary power driving. The real-time electrical signals of the electrode assembly may include, but are not limited to, real-time voltage, current, power, etc. flowing through the electrode assembly. The electrical signal flowing through the electrode assembly may be collected by an electrical signal collecting circuit (e.g., a voltage sampling circuit, a current sampling circuit, etc.), or may be collected by an electrical signal sensor (e.g., a voltage sensor, a current sensor, a power sensor, etc.), and a person skilled in the art may select a suitable collecting method according to actual situations in implementation, which is not limited in this application.

The power supply parameter is a power supply control parameter that needs to be output when the power supply control assembly supplies power to the electrode assembly, and may include, but is not limited to, any one or more of voltage, current, power, voltage frequency, and the like. The power supply control assembly can determine the power supply control parameters needing to be output when the power is supplied to the electrode assembly in real time according to the real-time electric signals of the electrode assembly, so that the real-time electric signals of the electrode assembly meet specific conditions when the power is supplied to the electrode assembly according to the power supply parameters. Here, different electric signals between two poles of the electrode assembly can generate different electric fields, so that different heat energy can be generated by food materials, and different cooking requirements can be met. Therefore, the specific condition may be a condition that needs to be met to achieve a specific cooking requirement, and when implemented, a person skilled in the art may determine the condition in consideration of an actual cooking requirement, and select an appropriate manner to determine the power supply parameter according to a relationship between the real-time electrical signal of the electrode assembly and the power supply parameter, which is not limited in the embodiment of the present application.

The cooking equipment provided by the embodiment of the application adopts the electrodes to apply the electric fields at the two ends of the food materials, so that current passes through the food materials, the heat energy can be generated under the action of the current inside the food materials by utilizing the impedance of the food materials, the food materials are heated, and the power supply parameters of the electrode assemblies are dynamically adjusted according to the collected real-time electric signals of the electrode assemblies. Therefore, when the electrode assembly is used for heating food materials, heat energy can be directly generated by the resistance of the food materials under the action of current to heat the food materials, the heat energy utilization rate is high, and the heating speed is high. Because the temperature gradient required by heat energy transfer in the traditional heating process is not available, the heating is uniform, a heat transfer surface is not needed, and the quality of food is not influenced. Further, in the heating process, the power supply parameters are dynamically adjusted in real time according to the real-time electric signals, so that different cooking requirements can be met, and the problem that the food material structure is damaged due to overlarge current flowing through the food material or the heating is too slow due to too small current can be avoided.

An embodiment of the present application provides a cooking apparatus, as shown in fig. 1A or 1B, the apparatus including: shell 110, insulating food tray 120, electrode subassembly 130 and power control subassembly 140, wherein:

Fig. 2A is a schematic structural diagram of a power control assembly according to an embodiment of the present disclosure, and as shown in fig. 2A, the power control assembly 140 includes: electric parameter acquisition module 141, control module 142 and pressure regulating module 143, wherein:

the electrical parameter acquisition module 141 is used for acquiring real-time electrical signals of the electrode assembly;

the control module 142 is configured to: obtaining the real-time electrical signal; determining power supply parameters according to the real-time electric signals, so that when the voltage regulating module supplies power to the electrode assembly according to the power supply parameters, the real-time electric signals of the electrode assembly meet specific conditions; controlling the voltage regulating module to supply power to the electrode assembly according to the power supply parameters;

the voltage regulating module 143 is configured to supply power to the electrode assembly according to the power supply parameter.

Here, the electrical parameter collecting module may be implemented by a specific logic circuit (e.g., a voltage sampling circuit, a current sampling circuit, etc.), or may be implemented by an electrical signal sensor (e.g., a voltage sensor, a current sensor, a power sensor, etc.).

The control module may be implemented by a specific logic circuit, and may also be a processor of the cooking apparatus. When implemented, the system may include, but is not limited to, a Central Processing Unit (CPU), a microprocessor Unit (MPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), or the like.

The pressure regulating module can also be realized by a specific logic circuit or a processor of the cooking device.

In some embodiments, as shown in fig. 2B, the power control component 140 further comprises: a regulated dc power supply 144, and a power output loop 145, wherein,

the direct-current stabilized power supply 144 is configured to supply power to the control module 142 and the electrical parameter acquisition module 141;

the power output circuit 145 is configured to output power to the electrode assembly 130 by using the power supply voltage output by the voltage regulating module 143;

correspondingly, the voltage regulating module 143 is further configured to determine the supply voltage according to the supply parameter, and output the supply voltage to the power output module 145.

Here, voltage regulation module and direct current constant voltage power supply are all provided electric drive by the commercial power, and voltage regulation module provides the alternating current for the power output return circuit, and direct current constant voltage power supply converts the commercial power into the direct current of voltage invariant, for control module and electric parameter acquisition module power supply.

The power control module 140 is shown in fig. 2A, and includes: electric parameter acquisition module 141, control module 142 and pressure regulating module 143, wherein:

In some embodiments, the real-time electrical signal comprises a real-time current value and the power supply parameter comprises a power supply voltage. Correspondingly, the control module is further configured to: acquiring a real-time current value of the electrode assembly; and determining a power supply voltage according to the real-time current value, so that the real-time current value of the electrode assembly is kept in a specific range when the voltage regulating module supplies power to the electrode assembly according to the power supply voltage.

Here, during the cooking process, the state of the food material (including water content, oil content, degree of ripeness, etc.) changes, while the food materials in different states have different electrical conductivity and electrical impedance characteristics, and the current passing through the food material under the same electric field will be different, so that the generated heat energy will also be different. Therefore, in order to maintain the real-time current value of the electrode assembly within a specific range, it is necessary to determine an appropriate power supply voltage according to the collected real-time current of the electrode assembly and supply power to the electrode assembly at the appropriate power supply voltage. For example, part of the food materials (e.g., frozen meat pieces, steak, etc.) may gradually decrease in impedance as the state changes during heating, and the supply voltage may need to be gradually decreased in order to maintain the real-time current value of the electrode assembly within a certain range.

In some embodiments, the control module is further configured to: and when the power supply voltage is smaller than a specific voltage threshold, adjusting the power supply voltage to ensure that the real-time current value of the electrode assembly is larger than the specific current threshold when the voltage regulating module supplies power to the electrode assembly according to the power supply voltage.

In some embodiments, the power supply parameter comprises a power supply. Correspondingly, the control module is further configured to: obtaining the heating time of the food material and the target doneness of the food material; inquiring a specific corresponding relation according to the heating duration and the target maturity to obtain target power supply power, wherein the specific corresponding relation is used for representing an incidence relation among the heating duration, the target maturity and the power supply power; and controlling the voltage regulating module to supply power to the electrode assembly according to the target power supply.

Here, the heating time period and the target doneness of the food material may be user-set or default values. The target doneness of the food material can be divided according to different particle sizes according to actual requirements, for example, the target doneness can be divided into three ripeness, five ripeness, seven ripeness, nine ripeness and the like according to a finer particle size, and the target doneness can also be divided into a younger ripeness, an older ripeness, a medium ripeness and the like according to a coarser particle size. The correlation between the heating time length, the target doneness and the power supply power may be determined by an experimental method and then stored in a local memory or a database. For example, when the target doneness is classified into tender doneness, older doneness, and moderate doneness, the correlation among the heating time, the target doneness, and the power supply is as shown in fig. 3, and when the heating power is constant, the longer the heating time is, the older the doneness of the food material is, and when the heating time is constant, the larger the heating power is, the older the doneness of the food material is.

In some embodiments, the control module is further configured to: acquiring the acquired real-time electric signals of the electrode assembly and the state information of the food material; and determining the power supply parameters according to the real-time electric signals and the state information.

Here, the state information of the food material may include, but is not limited to, a kind, a form, a water content, a heated time period, a cooking stage, etc. of the food material. In implementation, the state information of the food material may be preset by a user, or determined by the power control component through real-time detection of the food material in the food material tray, or determined by the power control component according to information preset by the user and a result obtained through the state detection of the food material in the food material tray.

Because the food materials with different state information have different electric conduction characteristics and electric impedance characteristics, the heat energy generated under the action of the same electric field is different, and the requirements of the food materials with different state information on heating are different during cooking. Therefore, when implemented, a person skilled in the art may select an appropriate manner to determine the power supply parameter according to the real-time electrical signal of the electrode assembly and the state information of the food material by considering the electrical conductivity and the electrical impedance of the food material in the food material tray and the relationship between the actual heating requirement and the power supply parameter, which is not limited in the embodiment of the present application. In some embodiments, different power supply parameters such as output voltage and voltage frequency can be determined according to different food material types and the obtained real-time electric signals, so as to control the heating process. In other embodiments, different power supply parameters can be determined according to the change of the obtained real-time electric signals when the same food material is cooked to different stages. For example, for cooking of frozen food materials, the food materials need to be thawed through a thawing stage first, and then the thawed food materials are cooked through a cooking stage, so that when the food materials are determined to be in the thawing stage, power supply parameters can be adjusted in real time according to changes of obtained real-time electric signals, so that the current flowing through the electrode assembly is kept small, and the food materials are prevented from being denatured due to large current.

Here, any suitable insulating material may be used for both the upper cover and the chassis. When the device is implemented, the upper cover can be completely separated from the chassis, or can be connected with the chassis through a rotating structure, and the rotating structure is utilized to realize buckling and separation with the chassis. The skilled person can select a suitable implementation manner according to practical situations, and the embodiments of the present application are not limited thereto.

The food tray is insulated from the plate-shaped electrodes, and the two plate-shaped electrodes are arranged in parallel and keep a certain distance to prevent the two electrodes from being directly conducted. When the base plate is buckled with the upper cover, the two plate-shaped electrodes are respectively clung to two opposite surfaces of the food material. The two opposing surfaces are determined by the positions where the two plate-like electrodes are disposed, and may be both upper and lower surfaces or both opposing side surfaces. When the electric field is applied, the two plate-shaped electrodes are respectively used as a positive electrode and a negative electrode to apply the electric field to the food positioned between the two electrodes.

An embodiment of the present application provides a cooking apparatus, as shown in fig. 1A or 1B, the apparatus including: shell 110, insulating food material dish 120, electrode subassembly 130, power control assembly 140, wherein:

Fig. 6 is a schematic structural diagram of a component of an electrode assembly according to an embodiment of the present disclosure, and as shown in fig. 6, each of the electrodes of the electrode assembly includes:

a hard conductive electrode slice 1311 for connecting to a power supply control assembly;

and a soft conductive sheet 1312 disposed between the hard conductive electrode sheet 1311 and the food material 200 and in soft contact with the surface of the food material 200.

Here, any suitable hard conductive material may be used for the hard conductive electrode sheet, including but not limited to stainless steel, new electrode materials (electrodes of titanium, platinum, etc.), and the like.

The flexible conductive sheet can be made of any suitable flexible conductive material, including but not limited to conductive rubber, conductive foam, etc., for example, the conductive rubber can be graphite nickel plated silicone rubber, silver filled silicone rubber, silver plated silicone rubber, nickel plated silicone rubber, copper plated silicone rubber, graphite filled silicone rubber, etc., and the conductive foam can be common conductive foam, nickel plated copper conductive foam, gold plated conductive foam, carbon plated conductive foam, tin plated conductive foam, conductive aluminum foil foam, conductive copper foil foam, etc.

In the cooking device provided by the embodiment of the application, the electrode assembly adopts the soft conducting strips to be in soft contact with the surface of the food material, so that when the surface of the food material is not a plane, the soft conducting strips can be well attached to the surface of the food material, and the problem that when the food material is heated by adopting a hard electrode plate, the current can only be locally contacted with the convex part on the surface of the food material, and the current can only be transmitted through the contacted part to cause uneven heating is avoided.

An embodiment of the present application provides a cooking apparatus, as shown in fig. 7, the apparatus includes: the machine base plate 710, the machine top cover 720, the insulated food pan 730, the power control assembly 740, the electrodes including the upper electrode 751 and the lower electrode 752, the control panel 760 can be used to cook the planar food material 200.

In some embodiments, the cooking apparatus may be used to thaw food material, the thawing process being as follows:

1) opening the upper cover 720 of the machine, and placing the food material 200 such as frozen steak on the lower electrode 752;

2) powering on the device, pressing the upper cover 720 of the machine downwards to make the upper electrode 751 and the lower electrode 752 tightly attached to two surfaces of the food material 200 respectively;

3) at this time, the two electrodes form a path with the food material 200 to generate a current, and the food material 200 is self-heated as a resistance to be thawed.

In some embodiments, the power control component may be an electronic control component used with the electrode, and the power control component is configured as shown in fig. 2B, and includes: the system comprises an electrical parameter acquisition module 141, a control module 142, a voltage regulating module 143, a direct current stabilized voltage power supply 144 and an electrical output loop 145, wherein the electrical parameter acquisition module 141 is used for capturing electrical signals such as voltage, current or power of an electrode in real time.

In some embodiments, the control module 142 adjusts power supply parameters such as different voltages and frequencies output by the power output circuit 145 through the voltage adjusting module 143 according to different electrical signals collected by the electrical parameter collecting module 141 to control the electrode to cook, so as to realize negative feedback adjustment, thereby preventing the current from flowing too much and damaging the food material structure.

In some embodiments, the cooking device may be used to cook meat products, and the doneness of the meat product may be more effectively controlled by controlling the power while cooking. Here, the matching relationship between time and power for different doneness can be obtained by experiment, and as shown in fig. 3, the higher the heating time is, the older the doneness of the food material is when the heating power is constant, and the higher the heating power is, the older the doneness of the food material is when the heating time is constant. In implementation, based on the collocation relationship, the appropriate heating power can be determined according to the set heating time and the set degree of maturity, and the appropriate heating time can also be determined according to the set heating power and the set degree of maturity.

According to the cooking device provided by the embodiment of the application, the traditional heating assembly of the heating plate is replaced by the electrode, and the heavy structure caused by the heating plate can be avoided. In addition, the heat energy generated by the impedance of the food material under the action of the current directly heats the food material, so that the heat energy utilization rate is high, the food material is uniformly heated, and the heating speed is high. Particularly for the thawing of meat, the meat can be thawed uniformly in a short time, and the original flavor of the food is reserved.

When the electrode heating is used for unfreezing frozen meat such as steak, due to the fact that meat blocks are extruded to a certain degree during freezing, the surfaces of the frozen meat blocks are often not flat, the meat blocks are unfrozen by using an electrode heating mode, and the electrodes and the surfaces of the meat blocks cannot be integrally attached and are only in local contact. This may cause the local area to mature when heated using a large current flow, but may not provide the need for rapid thawing when a small current is used. In view of this, an embodiment of the present application provides a cooking apparatus, as shown in fig. 7, the apparatus including: the machine base plate 710, the machine top cover 720, the insulated food pan 730, the power control assembly 740, the electrodes including the upper electrode 751 and the lower electrode 752, the control panel 760 can be used to cook the planar food material 200.

In some embodiments, the power control component may be an electronic control component used with the electrode, and the power control component is configured as shown in fig. 2B, and includes: the system comprises an electrical parameter acquisition module 141, a control module 142, a voltage regulating module 143, a direct current stabilized voltage power supply 144 and an electrical output loop 145, wherein the electrical parameter acquisition module 141 is used for capturing electrical signals such as voltage, current or power of an electrode in real time. The dc regulated power supply 144 is used for supplying power to the control module 142 and the electrical parameter collection module 141.

In some embodiments, the electrode assembly is constructed as shown in fig. 6, and each of the electrodes includes: a hard conductive electrode sheet 1311 and a soft conductive sheet 1312, wherein:

the hard conductive electrode slice 1311 is used for connecting a power supply control component;

the soft conductive sheet 1312 is disposed between the hard conductive electrode sheet 1311 and the food material 200, and is in soft contact with the surface of the food material 200.

The soft conducting sheet is made of soft conducting materials, and has the advantages that after food materials such as steak and the like are frozen, the shape is not always a plane, a bent shape exists, at the moment, if a hard electrode plate is used, only a plurality of vertexes are contacted with the electrode plate inevitably, and current can only be transmitted downwards through the points, so that uneven heating can be caused. And by adopting the soft conducting strips, the electrodes can be well attached to the surfaces of the food materials in a soft contact mode, so that the current is dispersed, and uniform heating is realized.

In some embodiments, the power control component may be an electronic control component used with the electrode, and the power control component is configured as shown in fig. 2B, and includes: the electrode assembly comprises an electrical parameter acquisition module 141, a control module 142, a voltage regulating module 143, a direct current stabilized voltage power supply 144 and an electric power output loop 145, wherein the electrical parameter acquisition module 141 is used for capturing electrical signals such as voltage, current or power of the electrode assembly in real time. The dc regulated power supply 144 is used for supplying power to the control module 142 and the electrical parameter collection module 141. In some embodiments, the control module 142 controls the electrode assembly 120 to cook by adjusting the power output circuit 145 to output different power supply parameters, such as voltage, frequency, etc., through the voltage adjusting module 143 according to the different electrical signals collected by the electrical parameter collecting module 141.

When thawing frozen pieces of meat, it is not appropriate to use a fixed voltage to power the electrodes, which can be dynamically adjusted by the power control assembly. During thawing, the voltage change over time is shown in fig. 8, and includes two time phases T1 and T2. At the stage of T1, the power control module continuously adjusts the voltage to make the current flowing through the electrode fluctuate within the designated range, and as time goes on, because the resistance of the meat block gradually decreases along with the thawing progress, therefore, the voltage applied to the electrode gradually decreases, when the voltage decreases to a certain degree, the contact electrode area of the meat block and the electrode increases, even completely fits, at this moment, the stage of T2 is entered, the power control module adjusts the voltage to make the current flowing through the electrode increase, and the purpose is to complete the thawing process within one to two minutes by means of electrode heating.
