The electrode groups are connected to a power supply for applying an electric field to the food materials when an electric energy is applied, so that an electric current passes through the food materials as conductors to generate heat energy to heat the food materials. This heating method mainly utilizes the electrical conductivity of the food materials to process and cook the food materials as a section of conductor in the circuit, which has the advantages of fast temperature rise, uniform heating, no pollution, high heat energy utilization rate, etc.

[0004] The above-mentioned cooking equipment has a single heating function, and regardless of the type of food material, it uses only one heating method. When cooking food materials without fluidity (solid food materials), the solid food materials cannot be in full contact with the two electrodes, resulting in uneven distribution of electric current, which makes the contacted part of the food materials cook quickly, and the uncontacted part of the food materials cook slowly, thereby causing uneven cooking and heating of the food materials. On the other hand, the internal resistance of the uneven solid food materials will be different, which will cause uneven electric field, resulting in over-heating of some parts and insufficient heating of other parts, poor heating uniformity, and affecting the cooking effect. It cannot meet the cooking needs of different types of food materials. SUMMARY

DETAILED DESCRIPTION

[0080] ​​For the purpose of making the purposes and embodiments of the present application more clear, the exemplary embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings of the exemplary embodiments of the present application.

Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0082] The terms "first", "second", "third", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar or identical objects or entities, and do not necessarily mean to limit the specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchanged under appropriate circumstances.

[0083] The terms "include" and "have" and any variations thereof are intended to cover but not exclusive inclusion, for example, a product or device including a series of components does not have to be limited to all the components listed clearly, but can include other components that are not listed clearly or inherent to these products or devices.

[0084] The present application proposes a cooking apparatus 100, which will be described below with reference to the accompanying drawings Figures 1-29 The cooking apparatus 100 is described.

[0085] Referring to Figure 1 The cooking apparatus 100 can include a cabinet 101. The cabinet 101 is formed with a receiving cavity 1013, which can provide installation space for various components in the cooking apparatus 100.

[0086] The cabinet 101 is configured to form the outer shell of the cooking apparatus 100, and the cabinet 101 can be used to protect the components located in the cabinet 101.

[0087] The cabinet 101 can be a hollow structure in a rectangular shape. It should be noted that in other embodiments, the cabinet 101 can also adopt other shapes of shell structures. The specific shape of the cabinet 101 can be adjusted as needed, which is not limited here.

[0088] Referring to Figure 2 In some embodiments, the cooking apparatus 100 can be a drawer-type cooking apparatus 100.

[0089] Specifically, the cabinet 101 of the drawer-type cooking apparatus 100 is a drawer box 1011 structure. The cabinet 101 can include the drawer box 1011, and the drawer box 1011 is formed with the above-mentioned receiving cavity 1013.

[0090] A drawer 1012 can be arranged in the drawer box 1011. The drawer 1012 is arranged in the drawer box 1011 in a slidable and retractable manner. The drawer 1012 can be arranged in a reciprocating and slidable manner through guide rails arranged on opposite side walls of the drawer box 1011.

[0091] In the embodiment, the drawer box 1011 can be provided with a drawer opening (not shown in the figure), and the drawer 1012 can be slidably pushed into the drawer box 1011 through the drawer opening. The drawer 1012 can also be slidably pulled out of the drawer opening.

[0092] Continuing to refer to Figure 1 In some embodiments, the cooking device 100 can include at least one cooking apparatus 10. The cooking apparatus 10 is arranged in the accommodation cavity 1013 and can be used for high-temperature cooking of food in a steaming or baking manner.

[0093] In the embodiment, the cooking apparatus 10 is mounted on the drawer 1012, and the cooking apparatus 10 can slide with the drawer 1012 relative to the drawer box 1011.

[0094] In some embodiments, the cooking apparatus 10 can include a main body. The main body can be formed with a cooking cavity 11, which can be a cavity for placing food materials.

[0095] The cooking apparatus 10 can include a heating assembly arranged in the cooking cavity 11, which is used for heating and cooking food materials in the cooking cavity 11.

[0096] In the embodiment, referring to Figure 4 The heating assembly can include two metal plates 2. The two metal plates 2 are arranged 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 the embodiment, the two metal plates 2 are arranged in parallel along the length direction.

[0097] Referring to Figure 3 The cooking device 100 can include a first power supply 20. The first power supply 20 is arranged in the accommodation cavity 1013, and the first power supply 20 is connected to the two metal plates 2 and used for supplying power, i.e., providing working voltage, to the two metal plates 2 when started.

[0098] When the first power supply 20 is started, the two metal plates 2 are electrified and work as electrodes to apply an electric field to food materials in the cooking cavity 11, so that the food materials generate heat energy by passing through an electric current.

[0099] When the two metal plates 2 work as electrodes, the electrodes usually heat the food by contacting the outer surface of the food. The food itself is a conductor, and when the current passes through the food after being electrified, the electric energy will be converted into heat energy inside the food, so that the temperature of the food is raised, thereby directly achieving the purpose of cooking the food.

[0100] The heating method of electrifying two electrodes can meet the cooking conditions of food with fluidity and ensure the uniformity of cooking of food with fluidity.

[0101] When the food does not have fluidity (solid food), if the first power source 20 is still started, the food is heated by the electrode electrification heating method, which is prone to problems of poor cooking uniformity and poor cooking effect.

[0102] Specifically, the food with non-fluidity cannot be in full contact with the two metal plates 2, and if the shape of the food is irregular or the surface has large differences, the area of contact between the electrode and the food may not be uniform, resulting in uneven distribution of current. Some areas may not be able to effectively transmit current due to insufficient contact, while other areas may be heated by too much current, thereby causing uneven heating.

[0103] In addition, the difference in electrical conductivity of different foods may cause the current to encounter different resistances when passing through the food. The current passing through the food will be affected by these differences, resulting in uneven electric field, causing some parts to be overheated and other parts to be underheated, poor heating uniformity, and affecting the cooking effect.

[0104] In order to solve the problem of single heating function of the existing cooking device 100 and meet the cooking uniformity of different regular foods, in the embodiment, with reference to Figure 4 The cooking device 10 can include a second power source 4. The second power source 4 is connected to a single metal plate 2 to supply power to the single metal plate 2. When the second power source 4 is started, the metal plate 2 connected thereto is electrified to be used as a heating plate to heat the food in the cooking cavity 11, so that the cooking cavity 11 can have two heating modes.

[0105] Specifically, the cooking device 10 can include two second power sources 4. The two second power sources 4 correspond to the two metal plates 2 and are arranged on the main body, and the two second power sources 4 are located outside the cooking cavity 11.

[0106] It should be noted that by arranging two second power sources 4, it can be determined whether to start one heating plate on one side or two heating plates on both sides to heat simultaneously or intermittently according to the type, quantity, and position of the food, so as to meet the cooking conditions required by the food.

[0107] In this embodiment, by setting the first power supply 20 and the second power supply 4 connected with the two metal plates 2, one cooking cavity 11 can have at least two cooking and heating modes for different food materials. In actual use, the cooking device 100 can start or switch different or optimal cooking and heating modes according to different food materials, so that different food materials are heated more evenly, which not only effectively shortens the cooking time of the food materials, but also makes the food materials achieve the best cooking effect.

[0108] For example, when cooking food materials with fluidity, the first power supply 20 can be started. At this time, the two metal plates 2 on both sides are used as two electrodes, and the food materials themselves are conductors. When the current passes through the food materials after being powered on, the electric energy will be converted into heat energy inside the food materials, so that the temperature of the food materials is raised, thereby achieving the purpose of directly cooking the food materials.

[0109] When the food materials to be cooked do not have fluidity, the food materials themselves cannot be in full contact with the two plates. At this time, the second power supply 4 can be selected to be started. At this time, the two metal plates 2 on the left and right sides are powered on and become heating plates. When the food materials need to be cooked at high temperature quickly, both of the second power supplies 4 on both sides are started, so that both of the heating plates on both sides are started to heat, and the cooking efficiency is high. When the food materials need to be cooked at low temperature slowly, only one side of the second power supply 4 is started to cook, so that the cooking conditions required by the food materials are achieved.

[0110] In some embodiments, the cooking device 10 can include an electrical connection part arranged on the main body. The first power supply 20 is connected with the two metal plates 2 through the electrical connection part, so as to supply power to the two metal plates 2 when the first power supply 20 is started. When the first power supply 20 is started, the two metal plates 2 are powered on and work as electrodes to apply an electric field to the food materials, so that the electric current passes through the food materials to generate heat energy for heating.

[0111] The two second power supplies 4 are respectively connected with the two metal plates 2 through the electrical connection part, so as to supply power to the metal plates 2 connected therewith when the second power supplies 4 are started. When the second power supply 4 is started, the metal plate 2 connected with the started second power supply 4 is powered on and works as a heating plate to provide heat to the food materials for heating.

[0112] In other embodiments, the first power supply 20 is connected with the two metal plates 2 through the electrical connection part to form a first power supply circuit. The two output terminals of the first power supply 20 are respectively connected to the two metal plates 2 arranged opposite to each other through the electrical connection part.

[0113] When the first power supply 20 is started, the first power supply circuit is turned on, so as to apply electric energy to the two metal plates 2 in the cooking device 10, so that the two metal plates 2 are powered on and work as electrodes to apply an electric field to the food materials in the cooking cavity 11, so that the electric current passes through the food materials to generate heat energy for heating.

[0114] In the embodiment, two second power supplies 4 are respectively arranged on the left and right sides of the main body, and a single second power supply 4 can be connected to the corresponding metal plate 2 through the power connection part to form a second power supply circuit.

[0115] When the second power supply 4 is started, the second power supply circuit is turned on to apply electric energy to the metal plate 2 connected thereto, so that the metal plate 2 is electrified to work as a heating plate to provide heat to the food in the cooking cavity 11 to heat the food.

[0116] In the embodiment, by arranging the first power supply circuit and the second power supply circuit, one cooking cavity 11 can have at least two food cooking and heating modes. The cooking device 100 can start or switch different or optimal cooking and heating modes according to different food in actual use, so that different food is heated more uniformly, which not only effectively shortens the cooking time of the food, but also makes the food achieve the best cooking effect.

[0117] Reference Figure 4 In some embodiments, the main body can include an inner container 1 which is detachably installed on the base 3.

[0118] The inner container 1 defines a cooking cavity 11 for containing food. The cooking cavity 11 can be provided with an opening at the top end of the cooking cavity 11, so that the food can be put into or taken out of the cooking cavity 11.

[0119] The metal plate 2 is arranged on the two first side plates 12 of the inner container 1, which is used to cook food after being electrified.

[0120] In the embodiment, the first side plate 12 extends along the length direction of the cooking cavity 11, and the two metal plates 2 are arranged on the first side plates 12 on the left and right sides. The length of the metal plate 2 is slightly smaller than the length of the second side plate 32. The metal plate 2 is arranged to cover the entire area of one side of the cooking cavity 11, so as to ensure the uniformity of cooking.

[0121] In some embodiments, referring to Figures 5-7 , the main body can include a power connection terminal 6. The power connection terminal 6 is arranged on the first side plate 12, and the power connection terminal 6 is connected to the metal plate 2.

[0122] In the embodiment, the power connection terminal 6 is arranged to facilitate the introduction of the power supply (the first power supply 20 and the second power supply 4) outside the cooking cavity 11 to the metal plate 2. It can be understood that the connection between the power connection terminal 6 and the metal plate 2 is an electrical connection, and the current can be introduced to the metal plate 2, so that the metal plate 2 can work normally to heat the food in the cooking cavity 11.

[0123] The main body can include a base 3, and the inside of the base 3 is hollow to define an installation cavity 31 for accommodating the inner container 1.

[0124] Reference Figure 8 、 Figure 9 The top of the base 3 has an opening, through which the inner container 1 can be installed in the installation cavity 31 or taken out of the base 3. The base 3 can have a rectangular hollow structure.

[0125] In this embodiment, the base 3 is fixedly connected to the drawer 1012. The base 3 can have a rectangular shape, and the two second power supplies 4 are installed on the left and right side walls of the base 3.

[0126] Further, the power connection part is arranged on the base 3, and the power connection part has elastic contacts 51 in the base 3. Referring to Figures 8-10 The elastic contacts 51 protrude towards the center of the base 3 relative to the side wall of the base 3.

[0127] When the inner container 1 is installed on the base 3, the power connection terminals 6 are in contact with the elastic contacts 51 to form an electrical connection. The metal plate 2 is electrically connected between the power connection terminals 6 and the elastic contacts 51. After the inner container 1 is removed, the power connection terminals 6 are disconnected from the elastic contacts 51, so that the metal plate 2 is not connected to the first and second power supply circuits.

[0128] In this embodiment, after the inner container 1 is removed, the metal plate 2 is disconnected from the elastic contacts 51 of the power connection part, avoiding the conduction of the first and second power supply circuits after the corresponding power supply is started. This not only prevents accidental heating when the inner container 1 is removed or not properly installed, but also increases the safety during use, ensures safety, and ensures that users will not encounter safety hazards when cleaning or handling the inner container 1 due to contact with the power supply part.

[0129] In some embodiments, the base 3 can include two second side plates 32 arranged opposite to each other. The second side plates 32 are arranged opposite to the first side plate 12 and extend along the length direction of the cooking cavity 11.

[0130] In this embodiment, the power connection part is arranged on the second side plate 32 of the base 3, and the second power supply 4 is installed on the second side plate 32, facilitating the connection of the second power supply 4 and the power connection part.

[0131] Referring to Figure 11 The first side plate 12 has an accommodation part 14 with an opening on the side away from the inner container 1, and the second power supply 4 is placed in the accommodation part 14 through the opening.

[0132] The opening of the accommodation part 14 is provided with a plurality of buckle structures 15, which are connected to the side of the second power supply 4 away from the accommodation part 14 after the second power supply 4 is installed, preventing the second power supply 4 from being pulled out of the opening.

[0133] The accommodation portion 14 is provided with a plurality of limiting portions 16 located at both ends in a first direction of the second power supply 4 to limit movement of the second power supply 4 in the first direction. The first direction can be a length direction of the second power supply 4 or a width direction of the second power supply 4.

[0134] In some embodiments, the metal plate 2 is detachably connected to the first side plate 12 by a fastener extending through the first side plate 12 to the outside of the cooking cavity 11 to form the electrical connection terminal 6.

[0135] In this embodiment, the detachable connection of the metal plate 2 is achieved by the fastener, which facilitates the disassembly and cleaning of the metal plate 2 while ensuring the connection strength of the metal plate 2 and the first side plate 12, and ensures that the metal plate 2 is stably installed in the correct position and is not easily loosened.

[0136] The fastener extends to the outside of the cooking cavity 11, which not only serves to fix the metal plate 2, but also forms the electrical connection terminal 6 connected to the elastic contact 51 to achieve the function of electrical connection, simplifies the structure design, and saves space and cost.

[0137] It should be noted that the fastener can be a bolt or a threaded column to screw the metal plate 2 to the first side plate 12.

[0138] In other embodiments, referring to Figures 13-15 , the electrical connection terminal 6 can be provided on the side of the metal plate 2 away from the center of the cooking cavity 11. Among them, one metal plate 2 corresponds to two electrical connection terminals 6, and the two electrical connection terminals 6 are arranged in a length direction of the metal plate 2.

[0139] Referring to Figure 15 , the first side plate 12 is provided with a first through hole 121 for the electrical connection terminal 6 to pass through, and the outer periphery of the electrical connection terminal 6 is provided with a first sealing member 71 which is interference fit in the first through hole 121.

[0140] In this embodiment, by providing the first sealing member 71, it can be avoided that the cooking flowing food material is overflowed to the outside of the cooking cavity 11 through the first through hole 121; in addition, this setting makes the metal plate 2 can be taken out, which is convenient for cleaning.

[0141] Referring to Figure 7 , in some embodiments, the side of the first side plate 12 facing the cooking cavity 11 is recessed with a receiving portion 13, and the metal plate 2 is embedded in the receiving portion 13.

[0142] The accommodating portion 13 is a groove structure. By embedding the metal plate 2 in the groove 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 equipment 100 achieve a more smooth and natural experience in vision and use.

[0143] Reference Figures 15-17 In some embodiments, the power connection part can include a plurality of elastic pieces 5, and the plurality of elastic pieces 5 are connected one by one with a plurality of power connection terminals 6. In the present embodiment, two elastic pieces 5 are arranged on each second side plate 32. That is, the power connection part can include four elastic pieces 5.

[0144] The elastic piece 5 is a cantilever structure with elasticity, one end of the elastic piece 5 is a conductive end 52 which is fixed relative to the second side plate 32, and the other end of the elastic piece 5 forms the elastic contact 51.

[0145] The two output ends of the first power supply 20 are respectively connected to the first conductive end arranged on the two second side plates 32, for providing electric energy for the two metal plates 2. The first conductive end is any one of the conductive ends 52 on the second side plate 32.

[0146] That is, one output end of the first power supply 20 is connected to any one of the conductive ends 52 on one second side plate 32, and the other output end of the first power supply 20 is connected to any one of the conductive ends 52 on the other second side plate 32. This arrangement allows the first power supply 20 to supply power to the two metal plates 2 arranged at intervals, so that the two metal plates 2 are used as electrodes after being electrified.

[0147] The two output ends of the second power supply 4 are respectively connected to the two conductive ends 52 on the second side plate 32 where the second power supply 4 is arranged. This arrangement allows the second power supply 4 to supply power to one metal plate 2, so that the electrified metal plate 2 is used as a heating plate.

[0148] By arranging the elastic piece 5, a stable and constant contact pressure between the elastic piece 5 and the power connection terminal 6 can be ensured, and stable electrical conduction between the power connection terminal 6 and the external power supply (the first power supply 20 and the second power supply 4) can be ensured, which can effectively avoid the problem of short circuit or poor contact between the power connection terminal 6 and the external power supply when the inner container 1 is disassembled or installed.

[0149] In the present embodiment, even if slight wear or deformation occurs during use, the elastic piece 5 can still maintain sufficient contact force to provide stable and reliable electrical connection.

[0150] Reference Figure 16 One end of the elastic piece 5 is provided with an arc-shaped portion 53, the arc-shaped portion 53 protrudes towards the direction of the cooking cavity 11 and is defined by a pressure processing to form the elastic contact 51.

[0151] In the embodiment, the arc-shaped part 53 is provided with a press type, which ensures the structural strength and the reliability of elasticity. When the inner container 1 is installed in the base 3, the electrical terminal 6 abuts against the elastic contact 51 of the elastic sheet 5, and the arc-shaped part can better distribute stress and ensure stable electrical connection.

[0152] In some embodiments, the end of the electrical terminal 6 away from the metal plate 2 is provided with a rounded corner, which ensures smooth contact with the elastic contact 51, ensures the reliability of the contact, and further provides stable and reliable electrical connection.

[0153] Reference Figure 17 In some embodiments, the second side plate 32 is provided with a mounting part 33 for accommodating the elastic sheet 5. The mounting part 33 is connected to the mounting cavity 31 and the accommodating cavity 1013. The end of the mounting part 33 away from the mounting cavity 31 is provided with a limiting sunken part 34, and the conductive end 52 is detachably connected to the limiting sunken part 34.

[0154] The limiting sunken part 34 can be provided with a connecting hole 341, and the conductive end 52 can be detachably connected to the connecting hole 341 through a screw.

[0155] In the embodiment, the limiting sunken part 34 is provided, which ensures that the elastic sheet 5 will not be deformed and will not deviate from the plane when it is compressed by the abutting force, thereby increasing the reliability of the elastic sheet 5.

[0156] Reference Figure 18 In some embodiments, the main body can include a cover plate 8, which is arranged on the inner container 1 to close the cooking cavity 11.

[0157] The cover plate 8 is provided with two handle 82 grooves 81 recessed towards the cooking cavity 11. Figure 19 The handle 82 grooves 81 are arranged in two and are spaced apart along the width direction of the cover plate 8.

[0158] The two handle 82 grooves 81 are provided with a handle 82, which is used by the user to hold and take.

[0159] The top surface of the handle 82 is in 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 grooves 81, preventing the hands from coming out during the process of the user taking the cover plate 8. In the embodiment, the two handle 82 grooves 81 are arranged left and right, which is convenient for the user to take.

[0160] In the embodiment, the handle 82 and the slot 81 are recessed towards the cooking cavity 11, so that the handle 82 has a hidden and embedded effect. The hidden design of the handle 82 makes the cover plate 8 and the appearance of the cooking device 100 more simple and beautiful, avoiding the exposure of additional components and reducing the visual clutter. At the same time, the handle 82 is integrally arranged with the cover plate 8, which is convenient for users to take.

[0161] Reference Figure 20 In some embodiments, the width of the handle 82 and the slot 81 is W. The height of the handle 82 and the slot 81 is H. Wherein, W≥15mm. H≥20mm.

[0162] It can be understood that the width direction of the handle 82 and the slot 81 is the width direction of the cover plate 8.

[0163] In the embodiment, by reasonably setting the width W and the height H of the handle 82 and the slot 81, the user's fingers are more comfortable, and the user experience is improved.

[0164] The width of the handle 82 and the slot 81 cannot be too small. If the width is too small, it may be difficult for the user's fingers to smoothly enter the handle 82 and the slot 81, especially for users with thicker or larger fingers, which may feel uncomfortable or difficult to operate. In order to ensure comfort, the width is set to be not less than a first parameter value, so that the user's fingers can smoothly enter the handle 82 and the slot 81. For example, the first parameter value can be 15mm-20mm, and a suitable parameter is selected in the specific design.

[0165] The width of the handle 82 and the slot 81 cannot be too small. If the width is too small, it may be difficult for the user's fingers to smoothly enter the handle 82 and the slot 81, especially for users with thicker or larger fingers, which may feel uncomfortable or difficult to operate. And if the width is too small, the user cannot firmly hold the handle 82, which may cause the hand to slip or lose control when opening and closing the cooking cavity 11, affecting the safety and fluency of use.

[0166] In order to ensure comfort, the width is set to be not less than a first parameter value, so that the user's fingers can smoothly enter the handle 82 and the slot 81, and the user can firmly hold the handle 82. For example, the first parameter value can be 15mm-20mm, and a suitable parameter is selected in the specific design.

[0167] The height of the handle 82 and the slot 81 cannot be too small. If the height is too small, the user's fingers may not be able to fully insert into the handle 82 and the slot 81, which may make it difficult to exert enough force when taking the cover plate 8, resulting in unsmooth or jammed operation.

[0168] In order to improve the user experience and operation safety, the height dimension is set to be not less than the second parameter value. For example, the second parameter value can be 20mm-25mm, and a suitable parameter is selected in the specific design.

[0169] In some other embodiments of the present application, in order to solve the problem that when the two metal plates 2 work as electrodes, the cooking uniformity is poor and the cooking effect is poor for solid food materials, with reference to Figure 21 , the cooking device 10 can include a needle level heating plate 9, which has a plurality of uniformly spaced heating needles 92.

[0170] It can be understood that the uniform spacing means that the same spacing is maintained between the plurality of heating needles 92.

[0171] The heating needles 92 are electrically connected to the corresponding metal plates 2, and the free ends of the heating needles 92 are located in the cooking cavity 11. When the first power supply 20 starts to cook the food material, the heating needles 92 can be inserted into the interior of the food material, so that the heat can be more uniformly distributed in each part of the food material, overcoming the problem of poor cooking effect caused by uneven contact and different resistance.

[0172] Specifically, when the first power supply 20 is started, power is supplied to the two metal plates 2, and at this time the heating needles 92 are inserted into the interior of the food material, increasing the contact area between the electrodes and the food material. A plurality of uniformly distributed heating needles 92 can be inserted into the interior of the food material when cooking the food material, so that the path of the current becomes more dispersed and uniform, and thus more current can flow through the interior of the food material, so that the food material is heated more uniformly, improving the cooking effect.

[0173] 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 container 1 corresponding to the two metal plates 2.

[0174] In this embodiment, the needle level heating plate 9 is designed to be detachable, so that the needle level heating plate 9 can be removed separately, facilitating cleaning and maintenance of the needle level heating plate 9 by the user.

[0175] 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 can ensure that the heating needles 92 are uniformly inserted into the interior of the food material, further ensuring the uniformity of the cooking of the food material.

[0176] In some embodiments, with reference to Figure 24 , the heating needles 92 on one of the needle level heaters are defined as first heating needles 921, and the heating needles 92 on the other needle level heater are defined as second heating needles 922, and the first heating needles 921 and the second heating needles 922 are staggered.

[0177] 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.

[0178] 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.

[0179] In some embodiments, the diameter of the heating needle 92 is d. Where d ≤ 5 mm or d ≥ 2 mm.

[0180] 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.

[0181] 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.

[0182] 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.

[0183] 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 side surfaces of the two first side plates 12 that are far apart from each other.

[0184] In other words, reference 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.

[0185] In this embodiment, the substrate 91 is designed to be detachable, which can be installed or detached according to different food materials or cooking needs, not only increasing the flexibility and application range of the equipment, but also facilitating the cleaning of the needle-level heating plate 9. In addition, the substrate 91 is located outside the cooking cavity 11, making the installation and removal process of the needle-level heating plate 9 more convenient.

[0186] The first side plate 12 is provided with a groove structure on the side away from the metal plate 2, and the substrate 91 is accommodated in the groove structure. Among them, the outer side of the substrate 91 can be flush with the outer side of the first side plate 12.

[0187] In some embodiments, the heating needle 92 is vertically connected to the side of the substrate 91 close to the metal plate 2. This setting makes the heating needle 92 more easily inserted and taken out, helping to ensure that the heating needle 92 can be uniformly inserted into the food material and the surface area in contact with the food material remains consistent.

[0188] The heating needle 92 arranged vertically to the substrate 91 can be directly inserted into the food material at different depths, thereby achieving more uniform heat distribution and avoiding the problem of some parts of the food material being overheated while other parts not being heated enough, meeting the cooking of more different types of food materials.

[0189] Reference Figure 22 , Figure 26 , the second through hole 911 is provided on the substrate 91. Among them, the second through hole 911 is provided for the power terminal 6 on the metal plate 2 to penetrate, and the power terminal 6 extends to the outside of the cooking cavity 11 through the second through hole 911, used for abutting with the elastic contact 51.

[0190] Reference Figure 25 , the 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. Among them, the heating needle 92 extends into the cooking cavity 11 by penetrating the corresponding first through hole 122 and second through hole 21 in sequence, so as to be inserted into the food material when cooking, avoiding the limitation of traditional heating plate that can only heat on the surface, improving the cooking uniformity, and being particularly suitable for cooking thicker or irregular shaped food materials.

[0191] In actual cooking control process, the heating intensity of the heating needle 92 can also be adjusted through the resistance change of the food material, overcoming the problem of poor cooking effect caused by uneven contact or different resistance in traditional heating method.

[0192] Reference Figure 27 In some embodiments, the two substrates 91 can be made of metal material, and the side of the two metal plates 2 away from each other is provided with a conductive part 93, and the conductive part 93 penetrates the corresponding first side plate 12 and abuts with the corresponding substrate 91 to form an electrical connection.

[0193] The arrangement makes the metal plate 2 charged, and the protruding conductive part 93 can be electrically connected to the external needle stage plate to power the substrate 91, ensuring that the several heating needles 92 are charged.

[0194] Of course, in other embodiments, the substrate 91 can be made of plastic material. The metal plate 2 is provided with a plurality of second perforations 21 corresponding to the plurality of heating needles 92, and the plurality of heating needles 92 are correspondingly arranged in the second perforations 21, and the heating needles 92 are connected with the inner wall of the corresponding second perforations 21, so that the heating needles 92 are electrically connected with the metal plate 2.

[0195] In this embodiment, the heating needle 92 is directly connected with the metal plate 2, reducing the transmission process of the current in the intermediate medium, reducing energy loss, improving heating efficiency, and ensuring rapid and uniform heating of food.

[0196] Continue to refer to Figure 27 In some embodiments, a second sealing member 72 is sealingly arranged between the substrate 91 and the first side plate 12. The second sealing member 72 is used to close the gap between the substrate 91 and the first side plate 12 to prevent the overflow of the flowing food during cooking.

[0197] Reference Figure 29 In some embodiments, when the inner container 1 is assembled in the base 3, the height of the top end of the second side plate 32 is higher than the height of the top end of the needle stage heating plate 9.

[0198] In the above embodiment, the height of the base 3 is set to be higher than the height of the needle stage heating plate 9, avoiding the user from contacting the needle stage heating plate 9 when taking out the inner container 1, reducing the risk of scalding, and improving the electrical safety performance.

[0199] Of course, in other embodiments, when the needle stage heating plate 9 is installed on the inner container 1, the second power source 4 can also be started to heat the food in the cooking cavity 11. At this time, the charged heating needle 92 can transfer the heat generated by it to the inside of the food, which is beneficial to improve the cooking uniformity.

[0200] In other embodiments, the cooking device 10 can include a temperature sensor. The temperature sensor adopts a temperature probe structure inserted into the food, and monitors the temperature of the contact part with the food in real time. According to the feedback temperature information, the current size or heating time can be dynamically adjusted to achieve more uniform heating effect.

[0201] In some embodiments, the cooking device 100 can include a controller. The controller can be arranged in the containing cavity 1013. The controller can be used to control the first power source 20 and the second power source 4 of the containing cavity 1013 to work.

[0202] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
