Description
Technical Field
[0001] This invention relates to the field of kitchen equipment, and more particularly to a cooking device. Background Technology
[0002] The cooking equipment may include a housing and a cooking cavity. The cooking cavity may be equipped with a heating element to heat the food inside the cooking cavity, thereby completing the cooking function.
[0003] In related technologies, the heating component may include a pair of electrodes in contact with the food. The electrodes are connected to a power supply and are used to apply an electric field to the food when electrical energy is applied, causing current to flow through the food as a conductor and generating heat to heat the food. This heating method mainly utilizes the electrical conductivity of the food, treating the food as a conductor in a circuit to process and cook the food. It has advantages such as rapid food heating, uniform heating, no pollution, and high thermal energy utilization.
[0004] The aforementioned cooking equipment has a single heating function, using only one heating method regardless of the type of food. Due to the different shapes of the food, the distance and contact area between different parts of the food and the heating element vary. As a result, different parts of the food are heated differently during the cooking process, leading to inconsistencies in the cooking results. For example, some parts may be overcooked, while others may be undercooked. Consequently, the quality of the food cooked by this equipment cannot be guaranteed, and it cannot meet the cooking needs of different shaped ingredients.
[0005] In view of the above, this application is hereby submitted. Summary of the Invention
[0006] The present invention aims to at least partially solve one of the technical problems in the related art.
[0007] Therefore, according to embodiments of this disclosure, a cooking apparatus is proposed, comprising:
[0008] The outer shell has a cavity inside;
[0009] A first power source is located within the receiving cavity;
[0010] At least one cooking device is disposed in the receiving cavity, the cooking device comprising:
[0011] The main body has a cooking cavity inside, used to hold the ingredients;
[0012] Heating assembly, comprising:
[0013] Two metal plates are respectively disposed on opposite side walls of the cooking cavity. The distance between corresponding points on the two metal plates is the same. The first power supply is connected to the two metal plates to supply power to the two metal plates when the first power supply is turned on.
[0014] Two second power supplies are disposed on the main body and located outside the cooking cavity, corresponding to the two metal plates respectively. The two second power supplies are connected to the two metal plates respectively and are used to supply power to the metal plates when the body is started.
[0015] When the first power supply is turned on, the two metal plates are energized and act as electrodes to heat the food.
[0016] When the second power supply is started, the metal plate connected to the started second power supply is energized and works as a heating plate to heat the food.
[0017] The controller is electrically connected to the first power supply and the second power supply, and the controller is configured to:
[0018] The preset cooking mode is determined based on the morphological information of the ingredients inside the cooking cavity;
[0019] According to the preset cooking mode, the power supply parameters of the first power supply and the second power supply are adjusted to adjust the heating power or working status of the heating component.
[0020] The above technical solution has the following advantages or beneficial effects: This solution can control the heating state of the metal plate using different power supplies, allowing for flexible adjustment of the heating method for the food, thus providing a more uniform and efficient heating effect. It automatically adjusts the power supply parameters of the first and second power supplies based on the shape information of the food, enabling the cooking equipment to switch between different cooking methods according to different food shapes, effectively avoiding the drawback of controlling the heating components to heat food using a single heating method when cooking different types of food. Furthermore, adjusting the heating power and the working state of the metal plate according to the shape of the food ensures uniform heating of the food, improving cooking uniformity.
[0021] According to an embodiment of this disclosure, if the food ingredient is in a liquid state, the second power supply is turned off and the first power supply is turned on, and the first power supply is controlled to supply power to the two metal plates at the upper limit of the output power until the cooking is finished.
[0022] The above technical solution has the following advantages or beneficial effects: when cooking liquid ingredients, the first power supply is controlled to supply power to the two metal plates at the upper limit of the output power, so that the two metal plates, after being energized, act as an electrode group to heat the ingredients with the maximum power, so as to ensure that the liquid ingredients can be heated quickly and evenly until the cooking is completed.
[0023] According to an embodiment of this disclosure, the cooking apparatus further includes a temperature detection component electrically connected to the controller for detecting the temperature of the food inside the cooking cavity;
[0024] The controller is configured to: if the morphology information of the food ingredient is liquid, then control the second power supply to be turned off, the first power supply to be turned on, and the first power supply to supply power to the two metal plates with a first output power;
[0025] If the detected temperature of the food exceeds the temperature threshold, the first power supply is controlled to supply power to the two metal plates with the second output power, and the temperature of the food is determined again to see if it exceeds the temperature threshold.
[0026] If so, control the first power supply to operate intermittently.
[0027] The above technical solution has the following advantages or beneficial effects: when the first power supply uses the second output power to power the metal plate to heat the food, the food can be kept at the temperature value required by the user by setting a preset time, so as to meet the user's requirements for the temperature and taste of the food; if the temperature cannot be reduced after adjusting the output power, the first power supply is intermittently disconnected, and the healthy cooking temperature is controlled by starting and stopping, and it is ensured that the food texture, taste or nutrients will not be lost due to excessive temperature during the heating process of liquid food.
[0028] According to embodiments of this disclosure, the cooking apparatus further includes a temperature detection component electrically connected to the controller, for detecting the food temperature in two detection areas near the metal plates on both sides of the cooking cavity, and the controller is further configured to:
[0029] If the food ingredient has an irregular solid shape, the first power supply is turned off, and based on the average vertical distance between the two metal plates and the solid food ingredient and the food temperature in the detected area, at least one second power supply is controlled to supply power to the metal plate connected to it, so as to adjust the heating power or working state of the heating component.
[0030] The above technical solution has the following advantages or beneficial effects: For irregular solid food, due to its irregular shape and different surface and internal heat conduction, the problem of uneven heating caused by poor contact between the first power supply and the food is avoided by turning off the first power supply. By turning on the second power supply and adjusting its heating power precisely according to the distance between the food surface and the metal plate, as well as the food temperature, the heating process can be made more gentle and uniform, avoiding charring or damage to the texture and taste of the food caused by excessive heating.
[0031] According to embodiments of this disclosure, the controller is further configured to:
[0032] If the average vertical distance between the solid food and the two metal plates is the same, then the two second power supplies are activated simultaneously to make the two metal plates work as heating plates to heat the food, and it is determined whether the temperature difference between the two inspected areas exceeds the set range.
[0033] If so, the heating of a single metal plate is turned off or on according to the food temperature control of the two inspected areas until the cooking is finished, so as to ensure that the food is heated evenly.
[0034] If not, the two metal plates will remain in operation as heating plates until cooking is finished.
[0035] The above technical solution has the following advantages or beneficial effects: when the distance between the food and the metal plate is the same, by detecting the temperature difference of the food and intelligently adjusting the heating strategy according to the temperature difference, the uniformity, energy saving and efficiency of the heating process are guaranteed, local overheating or undercooling can be avoided, the cooking quality and taste of the food can be improved, the maximum retention of nutrients can be ensured, and the user experience can be improved.
[0036] According to embodiments of this disclosure, the controller is further configured to:
[0037] If the average vertical distance between the solid food and the two metal plates is different, the second power supply connected to the first metal plate is activated, and after a preset time, the second power supply connected to the second metal plate is activated; wherein, the metal plate that is relatively far away from the food is defined as the first metal plate, and the other is defined as the second metal plate;
[0038] After the two second power supplies are turned on, it is determined whether the temperature difference between the two inspected areas exceeds the set range.
[0039] If not, the two metal plates will remain in operation as heating plates until cooking is finished.
[0040] The above technical solution has the following advantages or beneficial effects: By sequentially activating the first and second metal plates based on the different distances between the solid food and the two metal plates, a more precise heating sequence can be ensured. When the heating status (heating power or on / off) of the two metal plates can be dynamically adjusted according to the temperature difference of the food in the inspected area, and when the temperature difference is small, the two metal plates are controlled to maintain their heating plate state, ensuring that the food is heated evenly throughout the entire heating process.
[0041] According to an embodiment of this disclosure, the controller is further configured to: if so, control the heating of a single metal plate to be turned off or on according to the food temperature of the two inspected areas until cooking is finished; or, control the heating power of the corresponding metal plate to be adjusted according to the food temperature of the two inspected areas until cooking is finished, wherein the heating power of the metal plate decreases as the temperature of the metal plate and the corresponding food increases.
[0042] The above technical solution has the following advantages or beneficial effects: if the temperature difference of the food is too large, the controller can adjust the heating power of the two metal plates or turn off the heating function of a certain metal plate to avoid local overheating or overcooling, ensure uniform heating of the food, be highly efficient and energy-saving, and improve the quality of the food and retain its nutrients.
[0043] According to embodiments of this disclosure, the cooking apparatus further includes a component electrically connected to the controller:
[0044] A temperature detection component is used to detect the temperature of food in two detection areas near the two metal plates in the cooking cavity;
[0045] A resistance detection component is used to detect the resistance of the food ingredient;
[0046] The controller is also configured to:
[0047] If the morphological information of the food is a phase change food, then control the second power supply to be turned off and the first power supply to be turned on, and control the first power supply to supply power to the two metal plates at the upper limit of the output power.
[0048] The resistance of the food ingredient is acquired in real time. If the resistance of the food ingredient is greater than the preset resistance, the two second power supplies are activated and the first power supply is deactivated.
[0049] Determine whether the temperature difference between the two inspected areas is within a set range;
[0050] If so, the two metal plates will remain in operation as heating plates until cooking is finished.
[0051] The above technical solution has the following advantages or beneficial effects: By controlling the switching of power supplies, it can be ensured that the food is properly heated during the curing process, preventing cooking failure or overheating caused by uneven temperature. After curing, when the temperature difference of the food is within the set range, the two metal plates are controlled to maintain the working state of heating plates, ensuring that the food is heated evenly and avoiding overheating in some parts while other parts are not heated properly.
[0052] According to embodiments of this disclosure,
[0053] If not, the heating of a single metal plate is turned off or on according to the food temperature of the two inspected areas until cooking is finished; or, the heating power of the corresponding metal plate is adjusted according to the food temperature of the two inspected areas until cooking is finished, wherein the heating power of the metal plate decreases as the temperature of the metal plate and the corresponding food temperature of the inspected area increases.
[0054] The above technical solution has the following advantages or beneficial effects: if the temperature difference is too large, the controller can adjust the heating power or turn off the heating function of a certain metal plate to avoid local overheating or overcooling and ensure uniform heating of the food.
[0055] Another aspect of this application provides a cooking apparatus, comprising:
[0056] The outer shell has a cavity inside;
[0057] A first power source is located within the receiving cavity;
[0058] At least one cooking device is disposed in the receiving cavity, the cooking device comprising:
[0059] The main body has a cooking cavity inside, used to hold the ingredients;
[0060] Heating assembly, comprising:
[0061] Two metal plates are respectively disposed on opposite side walls of the cooking cavity, and the distance between corresponding points on the two metal plates is the same; the first power supply is connected to the two metal plates to supply power to the two metal plates when the first power supply is turned on.
[0062] Two second power supplies are disposed on the main body and located outside the cooking cavity, corresponding to the two metal plates respectively. The two second power supplies are connected to the two metal plates respectively and are used to supply power to the metal plates when the body is started.
[0063] The controller is electrically connected to the first power supply and the second power supply, and the controller is configured to:
[0064] Based on the morphological information of the food inside the cooking cavity, the first power supply and the second power supply are controlled to turn on and off, and the heating power or working status of the heating component is adjusted.
[0065] The above technical solution has the following advantages or beneficial effects: the heating state of the metal plate can be controlled by different power supplies, allowing for flexible adjustment of the heating method for the food.

Detailed Implementation
[0100] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.
[0101] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.
[0102] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.
[0103] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.
[0104] This application discloses a cooking apparatus 100, which is described below with reference to the accompanying drawings. Figures 1 to 33 The cooking equipment 100 is described.
[0105] refer to Figure 1 The cooking appliance 100 may include a housing 101. A receiving cavity 1013 is formed inside the housing 101, which can provide installation space for various components in the cooking appliance 100.
[0106] The housing 101 is configured to form the outer shell of the cooking appliance 100, and the housing 101 can be used to protect the components located inside the housing 101.
[0107] The housing 101 can be a rectangular hollow structure. It should be noted that in other embodiments, the housing 101 can also adopt other shapes of shell structures. The specific shape of the housing 101 can be adjusted as needed and is not limited here.
[0108] Reference Figure 2 In some embodiments, the cooking device 100 may be a drawer-type cooking device 100.
[0109] Specifically, the housing 101 of the drawer-type cooking appliance 100 has a drawer box 1011 structure. The housing 101 may include the drawer box 1011, and the aforementioned receiving cavity 1013 is formed inside the drawer box 1011.
[0110] Drawer box 1011 may be provided with drawer 1012. Drawer 1012 is provided inside drawer box 1011 in a pull-out manner. Drawer 1012 can be slidably and reciprocally arranged by means of guide rails provided on opposite side walls of drawer box 1011.
[0111] In this embodiment, the front end of the drawer box 1011 may be provided with a drawout opening (not shown in the figure), and the drawer 1012 can be slidably pushed into the drawer box 1011 through the drawout opening. The drawer 1012 can also be slidably pulled out from the drawout opening.
[0112] Continue to refer to Figure 1 In some embodiments, the cooking apparatus 100 may include at least one cooking device 10. The cooking device 10 is disposed in the receiving cavity 1013 and can be used for high-temperature cooking of food by means of steaming, baking, etc.
[0113] In this embodiment, the cooking device 10 is mounted on the drawer 1012, and the cooking device 10 can be pulled out and slid relative to the drawer box 1011 as the drawer 1012 moves.
[0114] In some embodiments, the cooking apparatus 10 may include a main body. A cooking cavity 11 is formed within the main body, which can be a cavity for holding food ingredients.
[0115] The cooking device 10 may include a heating component disposed within the cooking cavity 11 for heating and cooking the food within the cooking cavity 11.
[0116] In this embodiment, reference Figure 4The heating assembly may include two metal plates 2. The two metal plates 2 are respectively disposed on opposite side walls of the cooking cavity 11, and the distance between corresponding points on the two metal plates 2 is the same. That is, in this embodiment, the two metal plates 2 are arranged parallel to each other along their length direction.
[0117] refer to Figure 3 The cooking device 100 may include a first power supply 20. The first power supply 20 is disposed in the receiving cavity 1013 and is connected to two metal plates 2, and is used to supply power to the two metal plates 2, that is, to provide working voltage, when the device is started.
[0118] When the first power supply 20 is started, the two metal plates 2 are energized and act as electrodes to apply an electric field to the food in the cooking cavity 11, so that current flows through the food and heat energy is generated to heat the food.
[0119] When the two metal plates 2 function as electrodes, they typically heat and cook the food by contacting its outer surface. Since the food itself is a conductor, when electricity is applied and current flows through it, electrical energy is converted into heat energy within the food, raising its temperature and thus directly achieving the purpose of cooking.
[0120] The heating method using two electrodes can meet the cooking conditions of fluid ingredients and ensure the uniformity of cooking.
[0121] When the ingredients are not fluid (solid ingredients), if the first power supply 20 is still turned on and the ingredients are heated by energizing the electrodes, it is very easy to cause problems such as poor cooking uniformity and poor cooking effect.
[0122] Specifically, non-flowing food cannot fully contact the two metal plates 2. If the food has an irregular shape or significant surface differences, the contact area between the electrodes and the food may be uneven, resulting in uneven current distribution. Some areas may not receive sufficient current due to insufficient contact, while other areas may be heated by excessive current, leading to uneven heating.
[0123] In addition, the differences in conductivity between different ingredients can cause them to encounter varying resistances when current passes through them. These differences affect the current's propagation within the food, resulting in an uneven electric field. This can cause some parts to overheat while others remain underheated, leading to poor heating uniformity and negatively impacting the cooking results.
[0124] To address the issue of limited heating functionality in existing cooking equipment 100 and to ensure uniform cooking of ingredients with varying shapes, this embodiment refers to... Figure 4The cooking device 10 may include a second power supply 4. The second power supply 4 is connected to a single metal plate 2 and is used to supply power to the single metal plate 2. When the second power supply 4 is activated, the metal plate 2 connected to it is energized and used as a heating plate to heat the food in the cooking cavity 11, thereby enabling the cooking cavity 11 to have two heating modes.
[0125] Specifically, the cooking device 10 may include two second power sources 4. The two second power sources 4 are disposed on the main body corresponding to two metal plates 2, and the two second power sources 4 are located outside the cooking cavity 11.
[0126] It should be noted that by setting two secondary power sources 4, it is possible to determine whether to start heating with one heating plate on one side, heating with both heating plates on both sides simultaneously, or heating intermittently, depending on the type, quantity, and location of the ingredients, so as to achieve the cooking conditions required for the ingredients.
[0127] In this embodiment, by providing a first power supply 20 and a second power supply 4 connected to the two metal plates 2, a cooking cavity 11 can have at least two cooking and heating methods for different ingredients. In actual use, the cooking device 100 can activate or switch between different or optimal cooking and heating methods according to different ingredients, resulting in more even heating of different ingredients. This not only effectively shortens the cooking time but also allows the ingredients to achieve the best cooking effect.
[0128] For example, when cooking ingredients that are fluid, the first power supply 20 can be activated. At this time, the metal plates 2 on both sides are used as two electrodes. The ingredients themselves are conductors. When electricity is applied, the current passes through the ingredients, and the electrical energy is converted into heat energy inside the food, raising the temperature of the ingredients and thus achieving the purpose of directly cooking the ingredients.
[0129] When the food being cooked is not fluid, it cannot fully contact the side plates. In this case, the second power supply 4 can be activated, turning the metal plates 2 on both sides into heating plates. For food requiring rapid, high-temperature cooking, both second power supplies 4 are activated, ensuring both heating plates heat up for high efficiency. For food requiring slow, low-temperature cooking, only one side of the second power supply 4 needs to be activated to achieve the desired cooking conditions.
[0130] In some embodiments, the cooking apparatus 10 may include an electrical receiving part disposed on the main body. A first power source 20 is connected to two metal plates 2 through the electrical receiving part, and is used to supply power to the two metal plates 2 when the first power source 20 is turned on. When the first power source 20 is turned on, the two metal plates 2 are energized and act as electrodes to apply an electric field to the food, causing current to flow through the food and generating heat energy for heating.
[0131] Two secondary power sources 4 are electrically connected to two metal plates 2 via connecting parts, and are used to supply power to the metal plates 2 to which they are connected when the secondary power source 4 is started. When the secondary power source 4 is started, the metal plate 2 connected to the starting secondary power source 4 is energized and works as a heating plate to provide heat to the food to heat the food.
[0132] In some other embodiments, the first power supply 20 is connected to two metal plates 2 via a connecting part to form a first power supply circuit. Specifically, the two output terminals of the first power supply 20 are respectively connected to two metal plates 2 arranged opposite each other via the connecting part.
[0133] When the first power supply 20 is started, the first power supply circuit is turned on to apply electrical energy to the two metal plates 2 in the cooking device 10, so that the two metal plates 2 are energized and work as electrodes to apply an electric field to the food in the cooking cavity 11, so that current flows through the food and heat energy is generated.
[0134] In this embodiment, two second power sources 4 are respectively disposed on the left and right sides of the main body. Each second power source 4 can be connected to the corresponding metal plate 2 through the power receiving part to form a second power supply circuit.
[0135] When the second power supply 4 is started, the second power supply circuit is turned on to apply electrical energy to the metal plate 2 connected to it, so that the metal plate 2 works as a heating plate after being energized to provide heat to the food in the cooking cavity 11 to heat the food.
[0136] In this embodiment, by setting up a first power supply circuit and a second power supply circuit, a cooking cavity 11 can have at least two cooking and heating methods for different ingredients. In actual use, the cooking device 100 can activate or switch between different or optimal cooking and heating methods according to different ingredients, making the different ingredients heated more evenly. This not only effectively shortens the cooking time but also allows the ingredients to achieve the best cooking results.
[0137] Reference Figure 4 In some embodiments, the main body may include an inner liner 1, which is detachably installed in the base 3.
[0138] The inner liner 1 is defined with a cooking cavity 11 for holding food. The top of the cooking cavity 11 may be provided with an opening for food to be put into or taken out of the cooking cavity 11.
[0139] Metal plates 2 are disposed on two opposite first side plates 12 of the inner pot 1 for cooking food after power is applied.
[0140] In this embodiment, the first side plate 12 extends along the length of the cooking cavity 11, and two metal plates 2 are respectively disposed on the left and right sides of the first side plate 12. The length of the metal plates 2 is slightly smaller than the length of the second side plate 32. This arrangement ensures that the metal plates 2 cover the entire area of one side of the cooking cavity 11, guaranteeing uniform cooking.
[0141] In some embodiments, reference Figures 5-7 The main body may include a power terminal 6. The power terminal 6 is disposed on the first side plate 12 and is connected to the metal plate 2.
[0142] In this embodiment, an electrical terminal 6 is provided to allow external power sources (first power source 20, second power source 4) to be introduced into the metal plate 2 from the cooking cavity 11. It is understood that the connection between the electrical terminal 6 and the metal plate 2 is an electrical connection, allowing current to be introduced into the metal plate 2, thus enabling the metal plate 2 to heat normally and heat the food inside the cooking cavity 11.
[0143] The main body may include a base 3, and the interior of the base 3 is hollow, defining an installation cavity 31 for accommodating the inner liner 1.
[0144] refer to Figure 8 , Figure 9 The top of the base 3 has an opening, through which the inner liner 1 can be installed into the base 3 or removed from the base 3. The base 3 can be a rectangular hollow structure.
[0145] In this embodiment, the base 3 is fixedly connected to the drawer 1012. The base 3 can be rectangular, and the two second power supplies 4 are installed on the left and right side walls of the base 3, corresponding to the two metal plates 2.
[0146] Furthermore, the power connection part is disposed on the base 3, and the power connection part has a resilient contact 51 located in the base 3. (See reference) Figures 8-10 The elastic contact 51 protrudes from the side wall of the base 3 toward the center of the base 3.
[0147] When the inner liner 1 is installed on the base 3, the power terminal 6 and the elastic contact 51 make corresponding contact to form an electrical connection. The metal plate 2 is electrically connected to the base 3 via the power terminal 6 and the elastic contact 51. After the inner liner 1 is removed, the power terminal 6 and the elastic contact 51 are disconnected, so that the metal plate 2 is not connected to the first power supply circuit or the second power supply circuit.
[0148] In this embodiment, after the inner liner 1 is disassembled, the metal plate 2 is disconnected from the elastic contact 51 of the power supply part, which prevents the first power supply circuit and the second power supply circuit from being connected after the corresponding power is turned on. This not only prevents accidental heating after the inner liner 1 is disassembled or not installed correctly, increasing safety during use, but also ensures safety, ensuring that users will not encounter safety hazards due to contact with the power supply part when cleaning or handling the inner liner 1.
[0149] In some embodiments, the base 3 may include two second side plates 32 disposed opposite to each other. The second side plates 32 are disposed opposite to the first side plate 12 and extend along the length direction of the cooking cavity 11.
[0150] In this embodiment, the power receiving part is disposed on the second side plate 32 of the base 3, and the second power supply 4 is installed on the second side plate 32 to facilitate the connection between the second power supply 4 and the power receiving part.
[0151] refer to Figure 11 The first side plate 12 is provided with an open receiving part 14 on the side away from the inner liner 1, and the second power supply 4 is placed in the receiving part 14 through the open.
[0152] Multiple latching structures 15 are provided at the opening of the receiving part 14. After the second power supply 4 is installed, the latching structures 15 engage with the side of the second power supply 4 away from the receiving part 14 to prevent the second power supply 4 from coming out of the opening.
[0153] The receiving portion 14 is provided with a plurality of limiting portions 16, which are located at both ends of the second power supply 4 in a first direction, to limit the movement of the second power supply 4 in the first direction. The first direction can be the length direction of the second power supply 4 or the width direction of the second power supply 4.
[0154] In some embodiments, the metal plate 2 is detachably connected to the first side plate 12 by fasteners, which extend through the first side plate 12 to the outside of the cooking cavity 11 to form an electrical terminal 6.
[0155] In this embodiment, fasteners are used to achieve a detachable connection of the metal plate 2, which facilitates the disassembly and cleaning of the metal plate 2 while ensuring the connection strength between the metal plate 2 and the first side plate 12, ensuring that the metal plate 2 is stably installed in the correct position and is not easy to loosen.
[0156] The fasteners extend to the outside of the cooking cavity 11, which not only serve to fix the metal plate 2, but also form an electrical terminal 6 that connects to the elastic contact 51 to realize the function of electrical connection, simplifying the structural design and saving space and cost.
[0157] It should be noted that the fasteners can be bolts or threaded posts, so that the metal plate 2 is screwed onto the first side plate 12.
[0158] In some other embodiments, reference is made to Figures 13-15 The electrical terminals 6 can be located on the side of the metal plate 2 away from the center of the cooking cavity 11. Each metal plate 2 is connected to two electrical terminals 6, and the two electrical terminals 6 are spaced apart along the length of the metal plate 2.
[0159] refer to Figure 15 The first side plate 12 is provided with a first through hole 121 through which the power terminal 6 passes. The outer periphery of the power terminal 6 is provided with a first sealing member 71, which is interference-fitted in the first through hole 121.
[0160] In this embodiment, by providing the first sealing element 71, it is possible to prevent flowing ingredients from overflowing from the first through hole 121 to the outside of the cooking cavity 11 when cooking; in addition, this setting allows the metal plate 2 to be removed for easy cleaning.
[0161] refer to Figure 7 In some embodiments, the first side plate 12 is recessed on the side facing the cooking cavity 11, and the metal plate 2 is embedded in the receiving part 13.
[0162] The receiving part 13 has a recessed structure. By embedding the metal plate 2 into the recessed structure on the first side plate 12, the space of the entire cooking cavity 11 is not affected, the cooking area is increased, and the hidden design makes the cooking device 100 achieve a smoother and more natural experience in terms of both appearance and use.
[0163] refer to Figures 15-17 In some embodiments, the power receiving part may include multiple spring contacts 5, each of which is connected to a corresponding power receiving terminal 6. In this embodiment, each second side plate 32 is provided with two spring contacts 5. That is, the power receiving part may include four spring contacts 5.
[0164] The spring piece 5 is a flexible cantilever structure. One end of the spring piece 5 is a conductive end 52 and the conductive end 52 is fixed relative to the second side plate 32. The other end of the spring piece 5 has the aforementioned elastic contact point 51.
[0165] The two output terminals of the first power supply 20 are respectively connected to the first conductive terminals provided on the two second side plates 32, for providing electrical energy to the two metal plates 2. The first conductive terminal is any one of the conductive terminals 52 on the second side plate 32.
[0166] In other words, one output terminal of the first power supply 20 is connected to any conductive terminal 52 on one of the second side plates 32, and the other output terminal of the first power supply 20 is connected to any conductive terminal 52 on the other second side plate 32. This arrangement allows the first power supply 20 to supply power to two spaced-apart metal plates 2, enabling the two metal plates 2 to be used as electrodes after being energized.
[0167] The two output terminals of the second power supply 4 are respectively connected to two conductive terminals 52 on the second side plate 32. This arrangement allows the second power supply 4 to supply power to a metal plate 2, enabling the energized metal plate 2 to be used as a heating plate.
[0168] By setting the spring 5, a stable and constant contact pressure can be ensured between it and the power terminal 6, ensuring stable electrical conduction between the power terminal 6 and the external power supply (first power supply 20, second power supply 4), and effectively avoiding the problem of short circuit or poor contact between the power terminal 6 and the external power supply when the inner liner 1 is disassembled or installed.
[0169] In this embodiment, even if slight wear or deformation occurs during use, the spring 5 can still maintain sufficient contact force to provide a stable and reliable electrical connection.
[0170] refer to Figure 16 One end of the spring sheet 5 is provided with an arc-shaped part 53, which protrudes toward the cooking cavity 11 and is defined by a pressing process to form an elastic contact point 51.
[0171] In this embodiment, a pressing process is provided on the arc-shaped portion 53, which ensures both structural strength and the reliability of elasticity. When the inner liner 1 is installed inside the base 3, the electrical terminal 6 abuts against the elastic contact 51 of the spring piece 5. The arc-shaped portion can better distribute stress, ensuring a stable electrical connection.
[0172] In some embodiments, the end of the electrical terminal 6 away from the metal plate 2 is provided with a rounded corner to ensure smooth contact with the elastic contact 51, thereby ensuring reliable contact and further providing a stable and reliable electrical connection.
[0173] refer to Figure 17 In some embodiments, the second side plate 32 is provided with a mounting part 33 for accommodating the spring piece 5. The mounting part 33 connects the mounting cavity 31 and the accommodating cavity 1013. A limiting countersunk platform 34 is provided at one end of the mounting part 33 away from the mounting cavity 31. The conductive end 52 is detachably connected to the limiting countersunk platform 34.
[0174] The limiting platform 34 may be provided with a connection hole 341, and the conductive end 52 can be detachably connected to the connection hole 341 by screws.
[0175] In this embodiment, by setting a limiting sink 34, it is ensured that the spring piece 5 will not deform or detach from the plane when compressed by the resisting force, thus increasing the reliability of the spring piece 5.
[0176] refer to Figure 18. In some embodiments, the main body may include a cover plate 8, which is placed on the inner pot 1 to close the cooking cavity 11.
[0177] The cover plate 8 has two recessed handles 82 and grooves 81 that are recessed towards the cooking cavity 11. (Reference) Figure 19 There are two handle slots 82 and the two handle slots 81 are spaced apart along the width direction of the cover plate 8.
[0178] A handle 82 is provided between the two handles 82 and the slot 81, and the handle 82 is provided for the user to pick up and hold.
[0179] The top surface of the handle 82 is on the same plane as the top surface of the cover plate 8, and the two opposite ends of the handle 82 extend into the handle 82 groove 81, preventing the user's hand from slipping out while picking up the cover plate 8. In this embodiment, the two handles 82 grooves 81 are arranged on the left and right sides for easy access by the user.
[0180] In this embodiment, the handle 82 groove 81 is recessed towards the cooking cavity 11, giving the handle 82 a hidden, embedded effect. The hidden handle 82 design makes the cover 8 and the cooking device 100 appear simpler and more aesthetically pleasing, avoiding exposed extra parts and reducing visual clutter. At the same time, the handle 82 is integrated with the cover 8, making it convenient for the user to pick up.
[0181] refer to Figure 20 In some embodiments, the width dimension of the handle 82 slot 81 is W. The height dimension of the handle 82 slot 81 is H. Wherein, W≥15mm and H≥20mm.
[0182] It is understandable that the width direction of the handle 82 groove 81 is the same as the width direction of the cover plate 8.
[0183] In this embodiment, by reasonably setting the width W and height H of the handle 82 slot 81, the user's fingers can be placed more comfortably, thus improving the user experience.
[0184] The width of the handle 82 slot 81 should not be too small. An excessively small width may make it difficult for users to smoothly insert their fingers into the handle 82 slot 81, especially for users with larger or thicker fingers, potentially causing discomfort or operational difficulties. To ensure comfort, the width should be set to be no less than the first parameter value, guaranteeing that the user's fingers can easily fit into the handle 82 slot 81. For example, the first parameter value can be 15mm to 20mm; a suitable parameter should be selected during the specific design process.
[0185] The width of the handle 82 slot 81 should not be too small. If the width is too small, it may be difficult for the user to insert their fingers into the handle 82 slot 81 smoothly, especially for users with thicker or larger fingers, which may cause discomfort or difficulty in operation. In addition, if the width is too small, the user will not be able to grip the handle 82 firmly, and when opening and closing the cooking cavity 11, it is easy to slip or lose control, affecting the safety and smoothness of use.
[0186] To ensure comfort, the width dimension is set to be no less than the first parameter value, ensuring that the user's fingers can be easily placed into the handle 82 slot 81, so that the user can firmly grip the handle 82. For example, the first parameter value can be 15mm to 20mm. When designing, consider choosing a suitable parameter.
[0187] The height of the handle 82 slot 81 should not be too small. If the height is too small, the user's fingers may not be able to be fully inserted into the handle 82 slot 81, which may make it difficult to apply enough force when picking up the cover plate 8, resulting in unsmooth operation or jamming.
[0188] To improve user experience and operational safety, the height dimension should be set to be no less than the second parameter value. For example, the second parameter value can be 20mm to 25mm; a suitable parameter should be selected during the specific design process.
[0189] In other embodiments of this application, in order to address the problem of poor cooking uniformity and poor cooking effect when the two metal plates 2 are used as electrodes for solid food, reference is made to... Figure 21 The cooking apparatus 10 may include a needle-level heating plate 9, which has a plurality of heating needles 92 arranged at uniform intervals.
[0190] It is understandable that evenly spaced arrangement means that several heating needles 92 maintain the same spacing.
[0191] The heating needle 92 is electrically connected to the corresponding metal plate 2 and the free end of the heating needle 92 is located inside the cooking cavity 11. It can be inserted into the food when the first power supply 20 is turned on to cook the food, so that the heat can be distributed more evenly to all parts of the food, overcoming the problem of poor cooking effect caused by uneven contact and different resistance.
[0192] Specifically, when the first power supply 20 is activated, it supplies power to the two metal plates 2. At this time, the heating needles 92 are energized and inserted into the food, increasing the contact area between the electrodes and the food. Multiple evenly distributed heating needles 92 can be inserted into the food during cooking, making the current path more dispersed and uniform. This allows more current to flow through the food, resulting in more even heating and improved cooking performance.
[0193] In some embodiments, two needle-level heating plates 9 are provided, and the two needle-level heating plates 9 are detachably connected to the inner liner 1 corresponding to two metal plates 2.
[0194] In this embodiment, the needle-level heating plate 9 is designed to be detachable, allowing it to be removed separately for easy cleaning and maintenance by the user.
[0195] In some embodiments, the free ends of the heating needles 92 on the two needle-level heating plates 9 are on the same plane. That is, the free ends of the heating needles 92 on the left and right sides are aligned, which ensures that the heating needles 92 are evenly inserted into the food, further ensuring the uniformity of food cooking.
[0196] In some embodiments, reference Figure 24 The heating needle 92 on one of the needle-level heaters is defined as the first heating needle 921, and the heating needle 92 on the other needle-level heater is defined as the second heating needle 922. The first heating needle 921 and the second heating needle 922 are arranged alternately.
[0197] By staggering the first heating needle 921 and the second heating needle 922, a more uniform distribution of the electric field within the food can be ensured, resulting in more balanced heat transfer and further improving cooking uniformity.
[0198] In this embodiment, on a cross-section perpendicular to the length of the inner liner 1, the first heating needle 921 and the second heating needle 922 on the left and right needle-level heating plates 9 are arranged alternately. Similarly, on a cross-section perpendicular to the height of the inner liner 1, the first heating needle 921 and the second heating needle 922 on the left and right needle-level heating plates 9 are arranged alternately.
[0199] In some embodiments, the diameter of the heating needle 92 is d. Where d ≤ 5 mm or d ≥ 2 mm.
[0200] By reasonably setting the diameter of the heating needle 92, it is possible to avoid the heating needle 92 being too thick, which would affect the convenience of inserting food, and also to prevent the heating needle 92 being too thin, which could injure the user.
[0201] The diameter of the heating needle 92 should not be too large. An excessively large heating needle 92 will increase friction during insertion, affecting the ease of adding food and potentially causing solid food to break. To facilitate insertion, the diameter of the heating needle 92 should not exceed the first parameter value. For example, the first parameter value can be 5mm to 7mm. A suitable specific parameter should be selected during the design process.
[0202] The diameter of the heating needle 92 cannot be too small. If it is too small, it may encounter resistance when inserting it to cook harder ingredients, making operation difficult or even preventing complete insertion. Furthermore, improper operation or cleaning could pose a risk of injury to the user, and it is also inconvenient for daily cleaning and maintenance. To improve safety and convenience during use, the diameter of the heating needle 92 is set to be no less than the second parameter value. For example, the second parameter value can be 2mm to 2.5mm. A suitable specific parameter should be selected during the design process.
[0203] In some embodiments, the needle-level heating plate 9 may include a substrate 91. (Reference) Figure 22 , Figure 23 The two substrates 91 are detachably connected to the two mutually spaced sides of the two first side plates 12. That is, referring to... Figure 24 The two sides of the first side plate 12 in the thickness direction are respectively provided with a metal plate 2 and a substrate 91.
[0204] In this embodiment, the detachable design of the substrate 91 allows for installation or removal according to different ingredients or cooking needs, increasing the flexibility and applicability of the equipment and facilitating the cleaning of the needle-level heating plate 9. Furthermore, the substrate 91's location outside the cooking cavity 11 further simplifies the installation and removal process of the needle-level heating plate 9.
[0205] A groove structure is provided on the side of the first side plate 12 away from the metal plate 2, and the substrate 91 is accommodated in the groove structure. The outer side of the substrate 91 can be flush with the outer side of the first side plate 12.
[0206] In some embodiments, the heating pin 92 is vertically connected to the side of the substrate 91 near the metal plate 2. This arrangement makes it easier to insert and remove the heating pin 92, helping to ensure that the heating pin 92 can be evenly inserted into the food and maintain a consistent surface area in contact with the food.
[0207] The heating pins 92 arranged on the vertical substrate 91 can be directly inserted into the food at different depths, thereby achieving a more uniform heat distribution and avoiding the problem of some parts of the food being overheated while other parts are not fully heated, thus satisfying the cooking needs of more different types of food.
[0208] refer to Figure 22 , Figure 26 A second through hole 911 is provided on the substrate 91. The second through hole 911 allows the electrical terminal 6 on the metal plate 2 to pass through, and the electrical terminal 6 extends through the second through hole 911 to the outside of the cooking cavity 11 for contacting the elastic contact 51.
[0209] refer to Figure 25The first side plate 12 is provided with a first through hole 122 for the heating needle 92 to pass through, and the metal plate 2 on the same side is provided with a second through hole 21 for the heating needle 92 to pass through. The heating needle 92 passes through the corresponding first through hole 122 and second through hole 21 in sequence and extends into the cooking cavity 11. It is used to insert into the food while it is charged during cooking, which avoids the limitation of traditional heating plates that can only heat the surface and improves the uniformity of cooking. It is especially suitable for cooking thicker or irregularly shaped food.
[0210] In actual cooking control, the heating intensity of the heating needle 92 can also be adjusted by the change in the resistance of the ingredients, overcoming the problem of poor cooking effect caused by uneven contact or different resistance in traditional heating methods.
[0211] refer to Figure 27 In some embodiments, the two substrates 91 may be made of metal material, and conductive portions 93 are protruding on the side surfaces of the two metal plates 2 that are far apart from each other. The conductive portions 93 penetrate the corresponding first side plate 12 and abut against the corresponding substrate 91 to form an electrical connection.
[0212] This configuration allows the metal plate 2 to be electrically connected to the external needle plate via the protruding conductive part 93 when it is energized, thereby energizing the substrate 91 and ensuring that the heating needles 92 are energized.
[0213] Of course, in some other embodiments, the substrate 91 can be made of plastic material. The metal plate 2 is provided with a plurality of second through holes 21 corresponding to the plurality of heating needles 92, and the plurality of heating needles 92 are respectively inserted into the second through holes 21, and the heating needles 92 are connected to the inner wall of the corresponding second through holes 21 so that the heating needles 92 and the metal plate 2 are electrically connected.
[0214] In this embodiment, the heating needle 92 is directly electrically connected to the metal plate 2, which reduces the transmission process of current in the intermediate medium, reduces energy loss, improves heating efficiency, and ensures that the food is heated quickly and evenly.
[0215] Continue to refer to Figure 27 In some embodiments, a second sealing member 72 is provided between the substrate 91 and the first side plate 12. The second sealing member 72 is used to seal the gap between the substrate 91 and the first side plate 12 to prevent the overflow of flowing food during cooking.
[0216] refer to Figure 29 In some embodiments, when the inner liner 1 is assembled in the base 3, the top of the second side plate 32 is higher than the top of the needle-level heating plate 9.
[0217] In the above embodiment, the height of the base 3 is set to be higher than the height of the needle-level heating plate 9 to prevent the user from contacting the needle-level heating plate 9 when taking out the inner liner 1, thereby reducing the risk of burns and improving electrical safety performance.
[0218] Of course, in some other embodiments, when the needle-level heating plate 9 is installed on the inner pot 1, the second power supply 4 can also be activated to heat the food inside the cooking cavity 11. At this time, the energized heating needle 92 can transfer the heat it generates to the interior of the food, which helps to improve the uniformity of cooking.
[0219] In some other embodiments, the cooking apparatus 10 may include a temperature detection component. The temperature detection component employs a temperature probe structure inserted into the food to monitor the temperature of the part in contact with the food in real time. Based on the feedback temperature information, the current or heating time can be dynamically adjusted to achieve a more uniform heating effect. The temperature detection component may include a temperature sensor, which may be disposed within the heating needle 91.
[0220] In some embodiments, the cooking device 100 may include a controller. The controller may be located within the receiving cavity 1013. In actual use, the controller can be used to control the operation of the first power supply 20 and the second power supply 4 of the receiving cavity 1013 to activate different heating methods for different ingredients.
[0221] refer to Figure 30 This describes the cooking control logic of the cooking device 100 in this application for different ingredients.
[0222] The preset cooking mode is determined based on the morphological information of the ingredients in the cooking cavity 11 (S10);
[0223] According to the preset cooking mode, the power supply parameters of the first power supply 20 and the second power supply 4 are dynamically adjusted to adjust the heating power or working status of the heating component, so that the food is heated evenly (S20).
[0224] In this embodiment, by controlling the heating state of the metal plate 2 with different power supplies, the heating method of the food can be flexibly adjusted, thereby providing a more uniform and efficient heating effect. A preset cooking mode is determined based on the shape information of the food, and the power supply parameters of the first power supply 20 and the second power supply 4 are automatically adjusted. This allows the cooking device 100 to switch between different cooking methods according to different shapes of food, effectively avoiding the drawback of the cooking device 100 controlling the heating components to heat food in a single heating method when cooking different types of food. Furthermore, adjusting the heating power and the working state of the metal plate 2 according to the shape of the food ensures uniform heating of the food, improving cooking uniformity.
[0225] It is understood that power supply parameters may include, but are not limited to, any one or more parameters such as output voltage, output current, and output power. When the output voltage is zero, the corresponding power supply is off.
[0226] It is understandable that morphological information can include irregular solids (irregular solids before and after cooking), liquids (liquids before and after cooking), and phase-change foods (liquids before cooking and solids after cooking). Among them, irregular solid foods refer to solid foods with irregular shapes and no uniform standard form; liquid foods refer to foods with fluidity.
[0227] In this embodiment, by introducing the morphological information of the above three ingredients and controlling the two metal plates 2 to work in corresponding predetermined working modes through these three morphological information, the cooking device 100 can perform corresponding cooking modes for different forms of food. This allows the cooking device 100 to specifically meet the cooking needs of various forms of food, thereby improving the taste and nutritional value of the cooked food and reducing cooking time. This achieves the technical effect of optimizing the performance of the cooking device 100 and improving the user experience.
[0228] The cooking control logic for liquid ingredients in the cooking device 100 of this application includes the following steps:
[0229] If the food's physical state is liquid, then the second power supply 4 is turned off and the first power supply 20 is turned on. The first power supply 20 is then controlled to supply power to the two metal plates 2 at the upper limit of its output power until cooking is finished.
[0230] In the cooking control logic for liquid ingredients, the first power supply 20 is controlled to supply power to the two metal plates 2 at the upper limit of the output power, so that the two metal plates 2, after being energized, act as an electrode group to heat the ingredients at the maximum power, so as to ensure that the liquid ingredients can be heated quickly and evenly until the cooking is completed.
[0231] It should be noted that when cooking liquid ingredients, the first power supply 20 is activated, and the liquid ingredient acts as a conductor. The resistance of the conductor determines the cooking efficiency and energy saving effect; the lower the resistance of the ingredient, the higher the cooking efficiency under the same voltage. Therefore, to achieve the highest cooking efficiency, the voltage variation needs to be controlled according to the resistance value to ensure that the power reaches the maximum value for household use, i.e., the upper limit of output power.
[0232] In this embodiment, the cooking device 100 will detect the change in the resistance value of the food at any time, and calculate the upper limit of the output power as the standard. The relationship between the voltage value and the resistance value is p = U2 / R. By adjusting the output voltage change of the first power supply 20, it ensures that the power is supplied to the two metal plates 2 at the upper limit of the output power.
[0233] For example, the maximum power consumption in household use is 220V * 16A = 3520W.
[0234] refer to Figure 31 This describes the temperature-based cooking control logic of the cooking device 100 for liquid ingredients in this application.
[0235] When the food's physical state is liquid, the second power supply 4 is turned off, the first power supply 20 is turned on, and it supplies power to the two metal plates 2 with the first output power (S301).
[0236] Real-time detection of food temperature and determination of whether the detected food temperature exceeds the temperature threshold (S302);
[0237] In step S302, if the food temperature exceeds the temperature threshold, then step S303 is executed, controlling the first power supply 20 to supply power to the two metal plates 2 with the second output power.
[0238] After completing step S303, proceed to step S304 to monitor the food temperature in real time. If the food temperature exceeds the temperature threshold, control the first power supply 20 to work intermittently.
[0239] In this embodiment, when the first power supply 20 uses the second output power to power the metal plate 2 to heat the food, the food can be kept at the temperature value required by the user by setting a preset time, so as to meet the user's requirements for the temperature and taste of the food. If the temperature cannot be reduced after adjusting the output power, the first power supply 20 is intermittently disconnected, and the cooking temperature is controlled by starting and stopping. This ensures that the food will not lose its texture, taste or nutrients due to excessive temperature during the heating of liquid food.
[0240] It is understandable that when cooking liquid ingredients, the temperature of the ingredients in the cooking chamber 11 is the average of the temperature data detected by all temperature sensors.
[0241] In some embodiments, the cooking cavity 11 includes two opposing detection areas, which are respectively located near the metal plates 2 on both sides.
[0242] The temperature detection component can also be used to detect the food temperature in two detection areas of the metal plates 2 near both sides of the cooking cavity 11. In this embodiment, the temperature detection component may include two temperature probes. The two temperature probes are respectively connected to the center positions of the two metal plates, and the food temperature detected by them is used as the food temperature of the two detection areas.
[0243] If the food's shape information is an irregular solid, then the first power supply 20 is turned off, and based on the average vertical distance between the two metal plates 2 and the solid food, as well as the detected food temperature in the detected area, at least one of the second power supplies 4 is used to supply power to the metal plates 2, so as to adjust the heating power or working state of the heating component.
[0244] In this embodiment, for irregular solid ingredients, due to their irregular shape and different surface and internal heat conduction, the first power supply 20 is turned off to avoid uneven heating caused by poor contact between the energized and solid ingredients. By turning on the second power supply 4 and precisely adjusting the heating power of the second power supply 4 according to the average vertical distance between the ingredients and the metal plate 2 and the temperature of the ingredients in the two detected areas, the heating process is made more gentle and uniform, avoiding charring or damage to the texture and taste of the ingredients due to excessive heating.
[0245] In some embodiments, the cooking apparatus may include a position detection component for detecting the average vertical distance between the solid food and the metal plates 2 on both sides. In this embodiment, the average vertical distance between the solid food and the metal plates 2 on both sides is the average of the sum of the vertical distances from all points on the surface of the solid food facing the corresponding metal plate to the corresponding metal plate 2.
[0246] The position detection component can be a camera or an infrared depth sensor.
[0247] In order to reduce resource waste, reduce computational load and improve execution speed, in some other embodiments, the average vertical distance between the solid food and the metal plates 2 on both sides can be the average of the sum of the vertical distances between several points on the surface of the solid food facing the corresponding metal plate and the corresponding metal plate 2.
[0248] In practical use, this embodiment selects nine points on the surface of the solid food facing the corresponding metal plate, and uses the average value of the sum of the vertical distances between the nine selected points and the corresponding metal plate 2 to effectively improve data processing capabilities.
[0249] refer to Figure 32 This describes the cooking control logic of the cooking device 100 in this application for irregular solid ingredients.
[0250] If the food's shape information is an irregular solid, then execute step S401 to control the first power supply 20 to turn off and control the two second power supplies 4 to start.
[0251] After completing step S401, proceed to step S402 to determine whether the average vertical distance between the solid food and the two metal plates 2 is the same.
[0252] If the condition is met in step S402, then step S403 is executed, simultaneously activating the two second power supplies 4 to make the two metal plates 2 function as heating plates for heating. After step S403 is completed, step S404 is executed to determine whether the temperature difference between the two inspected areas exceeds the set range.
[0253] In step S404, if the difference exceeds the set range, then step S405 is executed, and the heating of a single metal plate 2 is turned off or on according to the food temperature control of the two inspected areas until the cooking is finished, so as to make the heating of the food uniform.
[0254] In step S404, if no, that is, if the difference is within the set range, then step S406 is executed to maintain the working state of the two metal plates 2 as heating plates until the cooking is finished.
[0255] In this embodiment, when the average vertical distance between the food and the metal plates 2 on both sides is the same, the heating strategy is intelligently adjusted based on the temperature difference of the food by detecting the temperature difference, which ensures the uniformity, energy saving and efficiency of the heating process, avoids local overheating or overcooling, improves the cooking quality and taste of the food, ensures the maximum retention of nutrients and improves the user experience.
[0256] It should be noted that the setting range can be specifically set according to different ingredients. The setting range can be [-2, 2].
[0257] Furthermore, if the average vertical distance between the solid food and the two metal plates 2 is different, the second power supply 4 connected to the first metal plate is activated, and the second power supply 4 connected to the second metal plate is activated after a preset time; wherein, the metal plate 2 that is relatively far away from the solid food is defined as the first metal plate, and the other is defined as the second metal plate.
[0258] After the two secondary power supplies 4 are activated, it is determined whether the temperature difference between the two inspected areas exceeds the set range.
[0259] If not, i.e. the difference exceeds the set range, the two metal plates 2 will remain in the working state as heating plates until the cooking is finished.
[0260] If so, i.e. the difference exceeds the set range, the heating of a single metal plate 2 is turned off or on according to the food temperature control of the two inspected areas until the cooking is finished; or, the heating power of the corresponding metal plate 2 is adjusted according to the food temperature control of the two inspected areas until the cooking is finished, wherein the heating power of the metal plate 2 decreases as the temperature of the metal plate 2 and the corresponding food increases.
[0261] In this embodiment, by sequentially activating the first and second metal plates based on the different average vertical distances between the food and the two metal plates 2, a more precise heating sequence can be ensured. The heating status (heating power or on / off) of the two metal plates 2 can be dynamically adjusted according to the temperature difference of the food in the inspected area.
[0262] When the temperature difference between the ingredients is small, the two metal plates 2 are kept in heating mode to ensure that the ingredients are heated evenly throughout the heating process. When the temperature difference between the ingredients is too large, the controller can adjust the heating power of the two metal plates 2 or turn off the heating function of one of the metal plates 2 to avoid local overheating or undercooling, ensuring even heating of the ingredients, high efficiency and energy saving, and improving the quality of the ingredients and the preservation of nutrients.
[0263] Specifically, please refer to Figure 32 In step S402, if not, then step S407 is executed to control the start of the second power supply 4 connected to the first metal plate, and after a preset time, the second power supply 4 connected to the second metal plate is started.
[0264] After completing step S407, step S408 is executed again to determine whether the temperature difference between the two inspected areas exceeds the set range.
[0265] If not in step S408, then step S406 is executed, maintaining the two metal plates 2 in the working state as heating plates until cooking is finished.
[0266] In step S408, if so, then step S407 is executed, and the heating of a single metal plate 2 is turned off or on according to the food temperature control of the two inspected areas until the cooking is finished; or step S409 is executed, and the heating power of the corresponding metal plate 2 is adjusted according to the food temperature control of the two inspected areas until the cooking is finished.
[0267] In some embodiments of this application, the greater the difference in vertical distance between the solid food and the two metal plates 2, the longer the corresponding preset time.
[0268] In this embodiment, by adjusting the heating start time based on the distance between the food and the heating plate, it is possible to ensure that the food in different positions receives even heating. When the food is closer to one side, the heating start time for that side is slightly delayed to avoid overheating or underheating. This ensures a more uniform heating process, thereby improving the cooking quality of the food.
[0269] In this embodiment, the controller can dynamically adjust the heating start timing of the two metal plates 2 according to the proportional relationship between the solid food and the metal plates 2 on the left and right sides.
[0270] Specifically, the position of the solid food is detected. If the food is in the center, the second power supply 4 connected to the metal plates 2 on both the left and right sides is activated simultaneously for cooking. At this time, the temperature of the food in the two detected areas is monitored at any time. If the temperature of the food on both sides tends to be the same, the working state of simultaneous heating of the metal plates 2 on both the left and right sides is maintained.
[0271] If the temperature difference between the two sides of the food is large, the heating of the metal plate 2 on one side will be turned on or off intelligently to control the internal temperature of the food until the cooking is finished.
[0272] If the solid food is biased to one side, the second power supply 4 connected to the first metal plate on the side furthest from the food will be activated first. The controller automatically calculates the distance ratio between the left and right metal plates 2 and determines the activation timing of the second power supply 4 connected to the metal plate 2, i.e., the timing of heating the metal plate 2, based on the ratio.
[0273] For example, the ratio has three levels: 1:2, 1:3, and greater than 1:3. When the ratio is no greater than 1:2, the time difference between the start-up of the two metal plates 2 is the corresponding preset time T1 minutes. When the ratio is no greater than 1:3, the time difference between the start-up of the two metal plates 2 is the corresponding preset time T2 minutes. When the ratio is greater than 1:3, the time difference between the start-up of the two metal plates 2 is the corresponding preset time T3 minutes. Where T1 is greater than T2, and T2 is greater than T1.
[0274] Furthermore, after the second power supplies 4 connected to both metal plates 2 are activated, the food temperature in the detected areas on both sides is detected again. Based on the food temperature in the detected areas on both sides, the timing of activating or deactivating the second power supplies 4 is adjusted to ensure uniform heating of the food. Specifically, if the food temperature in a detected area is higher, the second power supply 4 connected to the corresponding metal plate 2 is deactivated.
[0275] Of course, in some other embodiments, when cooking solid food, after the second power supply 4 connected to both metal plates 2 is turned on, the food temperature in the detected areas on both sides is detected again, and the output voltage of the second power supply 4 is adjusted according to the food temperature in the detected areas on both sides. Thus, the heating power of the metal plates 2 is adjusted to control the internal cooking temperature of the food. This control logic is maintained until the food temperature in the two detected areas tends to be the same until the food cooking is finished.
[0276] It is understood that the morphological information of the ingredients can be preset by the user, determined by the controller through real-time detection of the ingredients in the pot using detection components, or determined by the controller based on the user-preset information combined with the results obtained from detecting the state of the ingredients in the pot. Those skilled in the art can choose an appropriate method to determine the morphological information of the ingredients according to the actual situation during implementation, and the embodiments of this application do not limit this.
[0277] In some embodiments, the cooking apparatus may include a resistance detection component. The resistance detection component is used to detect the resistance of the food.
[0278] In this embodiment, after the food is placed in the container, its resistance can be detected, and its physical state can be determined based on this resistance. If the resistance of the food is infinite, its physical state is determined to be solid. If the resistance of the food is below a preset value, its physical state before cooking is determined to be liquid.
[0279] refer to Figure 33 This describes the cooking control logic of the cooking device 100 for phase change ingredients in this application.
[0280] If the morphological information of the food is phase change food, then control the second power supply 4 to turn off and the first power supply 20 to start, and control the first power supply 20 to supply power to the two metal plates 2 at the upper limit of the output power (S501).
[0281] After the first power supply 20 is started, the resistance of the food is acquired in real time, and then step S502 is executed to determine whether the resistance of the food is greater than the preset resistance.
[0282] In step S502, if yes, then step S503 is executed, controlling the two second power supplies 4 to start and the first power supply 20 to turn off; after executing step S503, step S504 is executed to determine whether the temperature difference of the food in the two inspected areas is within the set range.
[0283] If so in step S504, then step S505 is executed, maintaining the two metal plates 2 in the working state as heating plates until cooking is finished.
[0284] In this embodiment, by activating the first power supply 20 during the solidification process of the phase change food, it is possible to ensure that the food receives appropriate heating during the solidification process, preventing cooking failure or overheating caused by uneven temperature. After solidification, when the temperature difference of the food drops to the set range, the two metal plates 2 are controlled to maintain the working state of heating plates, ensuring that the food as a whole maintains a uniform heating state, and avoiding overheating of some parts of the food while other parts are still not heated properly.
[0285] Furthermore, in step S504, if no, that is, the temperature difference between the two inspected areas exceeds the set range, then step S506 is executed, and the heating of a single metal plate 2 is turned off or on according to the temperature of the two inspected areas until the cooking is finished; or, step S507 is executed, and the heating power of the corresponding metal plate 2 is adjusted according to the temperature of the two inspected areas until the cooking is finished, wherein the heating power of the metal plate 2 decreases as the temperature of the metal plate 2 and the corresponding inspected area increases.
[0286] In this embodiment, if the temperature difference between the food in the two detected areas is too large, the controller can adjust the heating power of the two metal plates 2, or turn off the heating function of one of the metal plates 2, to avoid local overheating or overcooling and ensure uniform heating of the food.
[0287] Specifically, if the morphological information of the food being cooked is that it is a phase change food, when the food is put in, the first power supply 20 is turned on, and the change in the resistance of the food is detected at any time. The first power supply 20 is controlled to calculate the output voltage u2 and the resistance R based on the upper limit value p. The relationship between the output voltage u2 and the resistance R is p = U2 / R. The output voltage changes with the change in resistance to ensure the fastest cooking speed.
[0288] When the resistance of the food exceeds the preset resistance, it indicates that the food is basically cooked. At this point, the first power supply 20 is turned off and the two second power supplies 4 are turned on simultaneously. The temperature of the food in the two detected areas is monitored at any time. If the temperature of the food in the two detected areas tends to be the same, the two metal plates 2 on the left and right sides are kept in a heating state to continue heating.
[0289] If the food temperatures in the two detected areas are inconsistent, the second power supply 4 connected to the single-sided metal plate 2 will be turned on or off intelligently, that is, the heating function of the single-sided metal plate 2 will be turned on or off to control the internal food temperature until the cooking is finished. Alternatively, the heating power of the left and right metal plates 2 can be controlled by adjusting the output voltage to control the internal cooking temperature of the food. Finally, the surface is heated to form a caramelized crust. This control logic is particularly suitable for cake cooking.
[0290] This application provides a cooking device 100, which includes a housing, a first power supply 20 disposed within the housing, and at least one cooking device. The cooking device includes a main body with a cooking cavity 11 formed inside, two metal plates 2 disposed on opposite sides of the cooking cavity 11, and two second power supplies 4 electrically connected to the two metal plates 2 respectively. When the first power supply 20 is activated, it supplies power to the two metal plates 2; when the second power supply 4 is activated, it supplies power to the metal plates 2 connected to it. The cooking device also includes a controller electrically connected to the first power supply 20 and the second power supplies 4. The controller is configured to control the first power supply 20 or the second power supply 4 to supply power to a heating element based on the shape information of the food inside the cooking cavity 11, and to adjust the heating power or operating state of the heating element to ensure uniform heating of the food.
[0291] During the cooking process, the heating state of the metal plate 2 can be controlled by different power sources, allowing for flexible adjustment of the heating method. By adjusting the heating strategy based on the shape information of the ingredients, the cooking equipment 100 can adapt to the cooking needs of different types of ingredients, thereby providing a more uniform and efficient heating effect and improving cooking uniformity.
