[0049] Specific implementation

[0050] ​​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0051] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0052] In addition, if the embodiments of the present application involve descriptions of "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, "and / or" or "and / or" appearing throughout the text means that the three parallel schemes are included, for example, "A and / or B" includes A scheme, or B scheme, or A and B simultaneously satisfy the scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection required by the present application.

[0053] The prior art mixed heating cooking appliance includes an electric heating device and an electromagnetic heating device arranged at the periphery of the electric heating device, and the electric heating device and the electromagnetic heating device are both used for heating a pot placed in a heating area of the cooking appliance. When the pot is a flat-bottomed pot, the electric heating device is mainly used for heating the flat bottom of the pot, and the electromagnetic heating device is used for heating the pot wall of the flat-bottomed pot, so that the distance between the electromagnetic heating device and the pot wall of the pot is small, which can ensure the coupling between the electromagnetic heating device and the pot wall of the pot, at a certain resonant voltage and current level, so that the unit area and unit time of the pot wall of the pot has enough electromagnetic energy converted into heat energy, and enough heating power is obtained.

[0054] However, when the cookware is a wok, the flat area of ​​the bottom of a typical wok has a small diameter, causing the area that would normally be heated by an electric heating element to be heated by an electromagnetic heating element. This increases the distance between the wok wall and the electromagnetic heating element. Since electromagnetic energy decays rapidly with increasing distance, this reduces the coupling between the electromagnetic heating element and the wok wall. Under relatively low resonant voltage and current levels, the rate at which electromagnetic energy is converted into heat energy per unit area and per unit time is insufficient, resulting in insufficient heating power, low wok temperature, and ultimately poor cooking results.

[0055] To solve the above technical problems, such as Figures 1 to 4 This utility model proposes a cooking utensil 100, including a main body 1, an electric heating device 2, an electromagnetic heating device 3, and an electronic control device (not shown in the attached drawings). The main body 1 includes a panel 11, on the upper side of which a recessed heating area 111 is provided. An electric heating device 2 is disposed within the main body 1 and is positioned corresponding to the heating area 111 to heat a cookware 200 placed in the heating area 111. An electromagnetic heating device 3 includes a first coil assembly 31 and a second coil assembly 32, both disposed within the main body 1. The first coil assembly 31 is positioned below the electric heating device 2, and its electromagnetic field can pass upward through the electric heating device 2 to electromagnetically heat the cookware 200 placed in the heating area 111. The second coil assembly 32 is positioned around the first coil assembly 31 and the electric heating device 2, and extends upward to at least the area corresponding to the side of the heating area 111 to electromagnetically heat the sidewall of the cookware 200. An electronic control device is electrically connected to the electric heating device 2 and the electromagnetic heating device 3 to control their operation.

[0056] The utility model discloses a cooking utensil 100, including the main body 1, the panel 11, the electric heating device 2, the electromagnetic heating device 3 and the electric control device, wherein, the main body 1 is the basic frame structure of the cooking utensil 100, and the space of providing support and containing other components is provided, the recessed heating area 111 of the panel 11 provides the specific position for the pot 200, so that the electric heating device 2 and the electromagnetic heating device 3 the heat generated can be concentrated in the heating area 111, and heating efficiency is improved. Figure 11 And Figure 12 As shown in the figure, wherein, the heating area 111 is recessed in the panel 11, and the distance between the pot wall of the pot 200 placed in the heating area 111 and the electromagnetic heating device 3 is reduced, the coupling between the electromagnetic heating device 3 and the pot wall of the pot 200 is increased, and at a certain resonant voltage and current level, so that the unit area and unit time of the pot wall of the pot 200 have enough electromagnetic energy converted into heat energy, so as to obtain enough heating power and improve the cooking effect.

[0057] It can be understood that the recess of the heating area 111 can be circular, square or other suitable geometric shape for the shape of the pot 200 to provide the best heating effect. At the same time, a plurality of heating areas 111 can be provided on the panel 11, and the plurality of heating areas 111 can be spaced apart or connected, and the recess shapes of the plurality of heating areas 111 can be the same or different.

[0058] It can be understood that, as Figure 7As shown, the depth of the heating area 111 can be designed to adapt to the specific cooking scenarios of the cooking appliance 100. For example, when the cooking appliance 100 needs to fry food, the depth of the heating area 111 can be designed to be shallow, so that the distance between the pot wall of the pot 200 and the second coil assembly 32 is moderate, so as to quickly reach a high temperature, which is suitable for rapid heating and stir-frying. When the cooking appliance 100 needs to cook soup or slow-cooked food, the depth of the heating area 111 can be designed to be deep, which can help the pot 200 to better retain heat, which is suitable for long-time low-temperature cooking, and can ensure the taste and nutrient composition of the food. In addition, it is worth mentioning that the bottom thickness of different pots 200 is different, and the depth of the heating area 111 should be designed considering the most common type of pot 200 to ensure the best heating effect. Therefore, in an embodiment, the depth of the heating area 111 is d1, and the d1 is at least 6 mm. When the depth of the heating area 111 is at least 6 mm (i.e. d1≥6 mm), the distance between the bottom of the pot 200 and the electromagnetic heating device 3 is small enough, thereby effectively improving the heating power density. The smaller distance helps the electromagnetic field to penetrate, reduces energy loss, and speeds up the heating speed. And the depth of more than 6 mm can better adapt to the pot bottom of different thicknesses, ensuring that even the thicker pot bottom can maintain a small distance with the electromagnetic heating device 3, realizing efficient heating.

[0059] It can be explained that, as Figures 3 to 6 As shown, in an embodiment, the heating area 111 can be vertically recessed on the panel 11, but in this embodiment, although it is beneficial to fix the cylindrical pot 200, it is not convenient to place the pot 200. Therefore, in an embodiment, the side of the heating area 111 is gradually outwardly expanded in the upward direction, and the second coil assembly 32 is adapted to the side of the heating area 111. In this way, the side of the heating area 111 is not vertical, but gradually outwardly expanded from the bottom to the top, which can provide a slope or stepped transition area, so that the pot 200 is more easily placed on the heating area 111, and the gradually outwardly expanded side can also adapt to pots 200 of different diameters, increasing the compatibility of the cooking appliance 100 to different pots 200. And the second coil assembly 32 is adapted to the side of the heating area 111, so that the shape and size of the second coil assembly 32 are designed according to the outwardly expanded shape of the side of the heating area 111. In this way, the position and layout of the second coil assembly 32 can ensure that the electromagnetic field uniformly covers the pot wall, reduces the heating dead angle, and improves the cooking efficiency. In addition, the outwardly expanded second coil assembly 32 can also increase the heating power of the side of the heating area 111 under the premise of limited height.

[0060] It can be explained that the heating area 111 on the panel 11 can be configured in various ways. For example, in an embodiment, the panel 11 is integrally provided, and the middle part is locally recessed to form the heating area 111. In this way, the panel 11 is integrally machined from a single material, and the middle part of the material is recessed to form the heating area 111. The integrally formed setting does not have a complex splicing or assembly process, and can provide better mechanical strength and heat resistance. In addition, cleaning and maintenance are more convenient because there are no gaps to hide dirt. In another embodiment, the panel 11 includes a plate body 112 and an intermediate plate 113, the middle part of the plate body 112 is provided with an opening, the periphery of the opening extends downward with an annular side 114, and the intermediate plate 113 is arranged in the opening and the outer edge thereof is spliced with the annular side 114. In this way, the annular side 114 can function to fix the intermediate plate 113 and provide a transition function. The intermediate plate 113 is arranged in the opening of the plate body 112, and the outer edge thereof is spliced with the annular side 114. This splicing can be welding, bonding or achieved by mechanical fixation and the like. In an embodiment, the periphery of the intermediate plate 113 is spliced with the annular side 114 by adhesive 115. In this way, compared with welding or mechanical fixation, the adhesive does not require complex equipment and process, simplifying the manufacturing process. Specifically, the adhesive 115 can be silicone adhesive. This splicing method reduces the complexity of the mold and the manufacturing cost compared to integrally formed. Integrally formed may require more complex molds and higher machining precision, while the splicing method is more flexible and facilitates separate production and assembly of different components.

[0061] It can be understood that the electric heating device 2 can be a resistance heating element, a ceramic heater, an infrared heater, etc. The specific selection can be set according to actual production needs. Specifically, in an embodiment, the electric heating device 2 includes an infrared heating device 21, and the infrared heating device 21 includes an infrared heating wire 211. In this way, high temperature is generated by the infrared heating wire 211 and infrared radiation is emitted. Infrared radiation: Infrared radiation is an electromagnetic wave that can be absorbed by food and converted into heat energy, thereby heating the food. Because infrared radiation can directly act on food, it reduces the loss of heat in the transmission process and improves the heating efficiency.

[0062] In an embodiment, the electric heating device 2 comprises a first heating portion 22 and a second heating portion 23 arranged in different zones, both of which are electrically connected to the electric control device, and the electric control device is capable of controlling the first heating portion 22 and the second heating portion 23 to work independently. In this way, by arranging in different zones, that is, the first heating portion 22 and the second heating portion 23 are divided into different areas in physical position, different heating areas 111 can be created on the cooking utensil 100 to meet different cooking needs. For example, one area can be used for rapid heating, and the other area can be used for low-temperature preservation. And the first heating portion 22 and the second heating portion 23 are electrically connected to the electric control device, and they can both receive power and instructions through the electric control device. So that the electric control device has the ability to control the first heating portion 22 and the second heating portion 23 to work independently, the user can adjust the heating area 111 and the power according to the different stages of cooking or the heating needs of different foods.

[0063] In an embodiment, the first heating portion 22 and the second heating portion 23 can be arranged relatively in the horizontal direction, and in another embodiment, the second heating portion 23 is located at the periphery of the first heating portion 22. In this way, it can better adapt to different sizes and shapes of pots 200, and the central area is suitable for small pots 200, and the peripheral area is suitable for large pots 200. The user can choose according to the size of the pot 200. In an embodiment, the second heating portion 23 is arranged in a ring shape. In this way, the second heating portion 23 arranged in a ring shape can provide uniform heat distribution in the ring-shaped area, providing all-round heat for food, which helps to cook evenly. In an embodiment, the first heating portion 22 and the second heating portion 23 are arranged in parallel. In this way, by arranging in parallel, the first heating portion 22 and the second heating portion 23 are respectively controlled independently, and the user can adjust the power of each heating portion according to the cooking needs, providing more flexible heating methods.

[0064] In an embodiment, as shown in Figure 10 The second heating portion 23 is located at the periphery of the first heating portion 22, and the first coil assembly 31 is located at the lower side of the first heating portion 22 and is arranged staggered with the second heating portion 23. In this way, by locating the first coil assembly 31 at the lower side of the first heating portion 22, the space in the up-down direction can be utilized, thereby reducing the volume of the arrangement and improving the space utilization.

[0065] In an embodiment, the first heating part 22 and / or the second heating part 23 is / are at least partially misaligned with the first coil assembly 31. In this way, only part of the heat generated by the first heating part 22 and / or the second heating part 23 can be conducted to the surface of the first coil assembly 31, reducing the temperature rise of the first coil assembly 31 caused by the electric heating device 2, thereby alleviating the problem of over-temperature caused by the heat generated by the electric heating device 2 superimposed on the heat generated by the first coil assembly 31 itself, reducing the probability of damage to the insulation layer of the first coil assembly 31, protecting the first coil assembly 31 from being burned out while improving the heating power of the cooking appliance 100. The first heating part 22 and the second heating part 23 can be misaligned with the first coil assembly 31 separately or simultaneously, the first heating part 22 can be partially or entirely misaligned with the first coil assembly 31, and the second heating part 23 can be partially or entirely misaligned with the first coil assembly 31.

[0066] In an embodiment, the second coil assembly 32 is arranged in a ring shape and includes multiple turns of coils arranged in layers in the up-down direction. In this way, the total inductive area of the coils can be increased by arranging the coils in layers, thereby improving the heating efficiency and making the cooking appliance 100 more energy-efficient.

[0067] In an embodiment, the first coil assembly 31 and the second coil assembly 32 are arranged in parallel to be independently controlled by the electric control device. In this way, by independently controlling the two coil assemblies, the heating range can be more accurately controlled, achieving a more uniform heating effect and avoiding the problem of food being burned or unevenly heated.

[0068] It can be understood that, as shown in Figure 8 The closer the distance between the second coil assembly 32 and the heating area 111, the greater the heating power density of the second coil assembly 32 on the pot wall of the pot 200 placed in the heating area 111. Therefore, in an embodiment, the height of the second coil assembly 32 beyond the heating area 111 towards the panel 11 is d2, and the d2 is at least 2 mm. In this way, the heating power density of the second coil assembly 32 on the pot wall of the pot 200 placed in the heating area 111 can be increased, and the cooking effect can be improved.

[0069] It can be understood that the heat of the electric heating device 2 will affect the electromagnetic heating device 3, thereby reducing the heating power of the electromagnetic heating device 3. For this purpose, in an embodiment, the cooking utensil 100 further comprises a heat insulation seat 4, which is arranged between the electric heating device 2 and the electromagnetic heating device 3. In this way, the heat insulation seat 4 can reduce the transmission of the generated heat of the electric heating device 2 to the electromagnetic heating device 3, thereby ensuring the normal use of the electromagnetic heating device 3 and keeping the heating power unchanged.

[0070] In an embodiment, as shown in Figure 9 The panel 11 comprises a plate body 112 and an intermediate plate 113, the middle part of the plate body 112 is provided with an opening, the periphery of the opening extends downward with an annular side part 114, and the intermediate plate 113 is arranged in the opening and the outer edge thereof is spliced with the annular side part 114; the distance between the outer edge of the intermediate plate 113 and the heat insulation seat 4 is d3, and the d3 is at least 2 mm. In this way, by keeping the distance (d3) between the outer edge of the intermediate plate 113 and the heat insulation seat 4 at least 2 mm, which is a safety distance, the material damage of the spliced joint between the intermediate plate 113 and the plate body 112 due to overheating is reduced, and the use safety of the cooking utensil 100 is increased.

[0071] In an embodiment, the upper end of the heat insulation seat 4 is recessed with a first groove 41 and a second groove 42, the second groove 42 is arranged in a spaced manner with the first groove 41, the first heating part 22 is arranged in the first groove 41, and the second heating part 23 is arranged in the second groove 42. In this way, the first groove 41 can provide a stable fixing position for the first heating part 22, and the second groove 42 can provide a stable fixing position for the second heating part 23, which can reduce the displacement of the first heating part 22 and the second heating part 23 during use, and improve the use safety of the cooking utensil 100.

[0072] The above is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by using the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
