Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a heating appliance. Background Art

[0002] Heating appliances such as induction cookers are indispensable household appliances and can be used in a variety of scenarios such as cooking, heating and keeping warm.

[0003] In the prior art, heating devices typically use electromagnetic heating. A coil generates an alternating magnetic field. When this field acts on a metal container placed on the heating device, it generates eddy currents, rapidly heating the bottom of the metal container and achieving the desired heating effect.

[0004] However, existing heating devices can only heat magnetic conductive metal containers and are not suitable for non-magnetic conductive containers, which limits the scope of use for users. Utility Model Content

[0005] The embodiment of the present application provides a heating device, which can solve the problem that the existing heating device can only heat magnetic metal containers and cannot be used for non-magnetic containers, thereby improving the application range of the heating device.

[0006] The present application provides a heating device, comprising: a shell assembly, comprising: a bottom shell and a heating panel, the bottom shell and the heating panel jointly defining an installation cavity; a magnetic thermal module, arranged in the installation cavity, the magnetic thermal module being used to heat a magnetic conductive container; an electric heating module, arranged on a side of the heating panel facing the installation cavity, the electric heating module heating a non-magnetic conductive container through the heating panel.

[0007] Thus, the heating device of the present application can heat magnetic containers using the magnetothermal module, and can also heat non-magnetic containers using the electric heating module. This makes the heating device suitable for both metal containers with excellent magnetic conductivity and non-magnetic containers (such as glass pots and ceramic pots). Users can freely choose containers of various materials for cooking, expanding the application range of the heating device.

[0008] In one possible implementation, the magnetocaloric module has a first heat-affected zone, and the electrothermal module has a second heat-affected zone, and the first heat-affected zone and the second heat-affected zone at least partially overlap.

[0009] In this way, the first heat-affected zone and the second heat-affected zone partially overlap, which can optimize the spatial layout of the heating device and reduce the area occupied by the heating panel. This compact layout design not only saves space, but also makes the structure of the heating device more compact.

[0010] In a possible implementation manner, at least one of the first heat-affected zone and the second heat-affected zone is centrally symmetric with respect to a center line of the heating panel.

[0011] In this way, at least one of the first and second heat-affected zones is centrally symmetrical about the centerline of the heating panel, making the heat-affected zones more evenly distributed across the heating panel. This symmetrical design ensures uniform heat distribution across the heating panel, avoiding localized overheating or cold spots. Furthermore, the symmetrical arrangement of the heat-affected zones allows the heating device to better adapt to containers of varying materials and shapes. Whether the container is round, square, or another shape, it can be effectively heated within the symmetrical heat-affected zones, improving the adaptability and flexibility of the heating device.

[0012] In a possible implementation, the magnetic thermal module is centrally symmetrical about a center line of the heating panel.

[0013] This creates a centrally symmetrical arrangement of the magnetocaloric modules about the centerline of the heating panel, ensuring a more even distribution of the heating area across the panel. Furthermore, this centrally symmetrical design provides a more balanced structure, reducing uneven physical stress caused by asymmetric heating and improving the panel's structural stability.

[0014] In a possible implementation, the magnetic thermal module includes a plurality of submodules, and the plurality of submodules are distributed around a center line of the heating panel.

[0015] In this way, the multiple submodules are distributed around the center line of the heating panel, so that the electromagnetic heating area of ​​the magnetocaloric module is more evenly distributed on the heating panel, further ensuring uniform heat distribution on the heating panel.

[0016] In one possible implementation, the electric heating module is centrally symmetrical about a center line of the heating panel.

[0017] This symmetrical arrangement of the heating modules around the centerline of the heating panel allows for a more even distribution of the heating coating across the panel, ensuring uniform heat distribution during heating. Furthermore, the centrally symmetrical heating modules provide a more balanced structure, reducing uneven physical stress caused by asymmetric heating and improving the panel's structural stability.

[0018] In one possible implementation, the electric heating module includes a first part and a second part, the first part is arranged in the central area of ​​the heating panel, and there are multiple second parts, which are evenly spaced along the circumference of the first part.

[0019] In this way, during electrical heating, the first and second parts of the electric heating module can jointly provide heat, ensuring a fast response and efficient operation of the heating process. Furthermore, the design of the first and second parts allows the heating device to better adapt to non-magnetic containers of various materials and shapes. Whether the container is round, square, or another shape, more effective heating can be achieved within the heating area formed by the first part in the center and the heating area formed by the second part distributed circumferentially, improving the adaptability and flexibility of the heating device.

[0020] In a possible implementation, the magnetic thermal module includes a plurality of submodules, and each of the submodules is located between two adjacent second parts.

[0021] In this way, the submodules of the magnetic thermal module are distributed between the two adjacent second parts of the electric heating module, making the structure of the heating panel more compact and reducing the occupied area of ​​the heating module, which not only saves space but also makes the overall layout of the heating device more reasonable.

[0022] In one possible implementation, the magnetocaloric module includes a coil disk.

[0023] In this way, by setting a coil disk in the magnetocaloric module, an alternating magnetic field can be generated, which can generate eddy currents at the bottom of the magnetic container, quickly heating the magnetic container, reaching the required temperature in a short time, and improving heating efficiency.

[0024] In a possible implementation, the electric heating module includes an electric heating coating, and the electric heating coating is coated on a surface of the heating panel facing the installation cavity.

[0025] In this way, the electric heating module, by providing an electric heating coating, can cover a larger area, ensuring uniform heating across the entire heating panel. Furthermore, the electric heating coating is thinner and lighter than traditional electric heating elements (such as resistance wire), reducing the weight of the heating device and making it more portable.

[0026] In one possible implementation, the heating device further includes: a container identification sensor, disposed in the mounting cavity, the container identification sensor being configured to identify the type of container disposed on the heating panel, the types including magnetic conductive containers and non-magnetic conductive containers; a control device, respectively connected to the container identification sensor, the magnetic thermal module and the electric heating module, the control device being configured to control the operation of the magnetic thermal module or the electric heating module according to the identification result of the container identification sensor.

[0027] In this way, the container recognition sensor can automatically identify the type of container placed on the heating panel, including both magnetic and non-magnetic containers. This automatic recognition function reduces the number of user steps and improves the intelligence of the heating device. Furthermore, the control device automatically selects the appropriate heating method based on the container type. For magnetic containers, the magnetic heating module is activated for electromagnetic heating; for non-magnetic containers, the electric heating module is activated for heating, improving the efficiency of the heating process.

[0028] The heating device provided herein, by providing both a magnetic heating module and an electric heating module, can heat both magnetic and non-magnetic containers. This makes it suitable for both metal containers with excellent magnetic conductivity and non-magnetic containers (such as glass and ceramic pots). This allows users to freely choose containers of various materials for cooking, broadening the range of applications for the heating device. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] As demonstrated in the background, heating devices typically utilize electromagnetic heating. These devices generate an alternating magnetic field through a coil. When this field acts on a metal container placed on the device, it generates eddy currents, rapidly heating the bottom of the container and achieving the desired effect. However, existing heating devices can only heat metal containers with excellent magnetic conductivity and are not suitable for non-magnetic containers, limiting their potential for use.

[0043] In view of this, the present application provides a heating device, which can heat magnetic containers and non-magnetic containers by setting a magnetic thermal module and an electric heating module, so that the heating device can be suitable for both metal containers with excellent magnetic conductivity and non-magnetic containers (such as glass pots, ceramic pots, etc.), thereby improving the scope of application of the heating device.

[0044] Reference below Figure 1 and Figure 2 The present invention provides a heating device, which can be an induction cooker or other type of heating device. The heating device of this embodiment includes a housing assembly 100. The housing assembly 100 includes a bottom shell 110 and a heating panel 120. The bottom shell 110 and the heating panel 120 together define a mounting cavity 130.

[0045] The bottom shell 110 primarily supports and protects the internal components, while also providing a structural foundation for mounting and securing the heating panel 120. The heating panel 120 evenly conducts heat to the bottom of the container, and as the surface layer of the heating device, the heating panel 120 protects the magnetocaloric module 200, the electric heating module 300, and the control device 500 within the heating device from the external environment. The mounting cavity 130, defined by the bottom shell 110 and the heating panel 120, is used to mount and accommodate the internal components of the heating device, including the magnetocaloric module 200, the electric heating module 300, the container identification sensor 400, and the control device 500.

[0046] In one possible design, the bottom housing 110 is typically made of a metal material (such as stainless steel or aluminum alloy) or high-strength plastic to ensure structural stability and durability. The heating panel 120 can be made of a highly thermally conductive material to ensure that the heat generated by the electric heating module 300 is transferred to the bottom of the container. For example, the heating panel 120 can be made of materials such as microcrystalline glass, ceramic glass, tempered glass, and quartz glass.

[0047] The heating device also includes a magnetic thermal module 200 and an electric heating module 300, which are disposed within the mounting cavity 130. The magnetic thermal module 200 is used to heat magnetically conductive containers, such as metal cookware. The electric heating module 300 is disposed on the side of the heating panel 120 facing the mounting cavity 130 and heats non-magnetic containers, such as ceramic cookware, through the heating panel 120.

[0048] In order to avoid mutual interference between the magnetic thermal module 200 and the electric thermal module 300, the magnetic thermal module 200 and the electric thermal module 300 can be arranged in the installation cavity 130 in a mutually avoiding manner to ensure that the magnetic thermal module 200 and the electric thermal module 300 do not interfere with each other in space and work independently.

[0049] In one possible design, the magnetic thermal module 200 can be fixed in the installation cavity 130 by a fixing bracket, and one end of the fixing bracket is fixedly connected to the bottom shell 110 to ensure its stability and reliability. The electric heating module 300 can also be fixed in the installation cavity 130 by a fixing bracket. The height of the magnetic thermal module 200 and the electric heating module 300 in the installation cavity 130 can be the same, and the edges of the magnetic thermal module 200 and the electric heating module 300 can be designed to be complementary shapes to ensure that the two can fit tightly to form an integral heating surface without obvious gaps. Alternatively, the electric heating module 300 can be higher than the magnetic thermal module 200, that is, the electric heating module 300 can fit tightly with the heating panel 120.

[0050] Furthermore, the magnetic thermal modules 200 and the electric thermal modules 300 can be installed in a staggered arrangement within the mounting cavity 130, with one magnetic thermal module 200 installed next to an electric thermal module 300, or a submodule of a magnetic thermal module 200 installed next to a submodule of an electric thermal module 300, alternating in sequence. This maximizes the space within the heating panel 120 while preventing interference between the two heating methods. The distance between each module or submodule can be maintained at approximately 1-2 cm to ensure sufficient heat dissipation space.

[0051] In the specific implementation process, the electric heating module 300 should be installed parallel to and close to the heating panel 120. This ensures that the heat generated by the electric heating module 300 can be efficiently and evenly transferred to the bottom of the container through the heating panel 120.

[0052] Thus, the heating device of the present application can heat magnetic containers using the magnetic heating module 200, and can also heat non-magnetic containers using the electric heating module 300, making it suitable for both magnetic and non-magnetic containers (such as glass pots and ceramic pots). Users can freely choose containers of various materials for cooking, expanding the application range of the heating device.

[0053] In a possible implementation, the magnetothermal module 200 has a first heat-affected zone, the electrothermal module 300 has a second heat-affected zone, and the first heat-affected zone and the second heat-affected zone at least partially overlap.

[0054] It is understood that the first heat-affected zone may refer to the area affected by the heat generated by electromagnetic induction when the magnetocaloric module 200 is in operation. The first heat-affected zone is concentrated above and around the magnetocaloric module 200. The second heat-affected zone may refer to the area affected by the heat generated by the electric heating element when the electric heating module 300 is in operation. The second heat-affected zone is also concentrated above and around the magnetocaloric module 200.

[0055] In one possible design, the first heat-affected zone and the second heat-affected zone can partially overlap at the center of the heating panel 120, thereby forming a highly efficient overlapping heating zone at the center of the heating panel 120. In this way, at the center of the heating panel 120, i.e., the overlapping portion of the first heat-affected zone and the second heat-affected zone, both magnetically conductive containers and non-magnetic conductive containers can be heated.

[0056] In this way, by partially overlapping the first heat-affected zone and the second heat-affected zone, the spatial layout of the heating device can be optimized and the occupied area of ​​the heating panel 120 can be reduced. This compact layout design not only saves space but also makes the structure of the heating device more compact.

[0057] In a possible implementation, at least one of the first heat-affected zone and the second heat-affected zone is centrally symmetric with respect to a center line of the heating panel 120 .

[0058] Optionally, the first heat-affected zone and the second heat-affected zone are both centrally symmetrical about the center line of the heating panel 120, and the first heat-affected zone and the second heat-affected zone are both located at the center of the heating panel 120, so that either the magnetic thermal module 200 or the electric heating module 300 can heat the container placed in the center area of ​​the heating panel 120.

[0059] In a specific implementation, the magnetic thermal module 200 can be designed to have one or more regions that are centrally symmetric about the center line of the heating panel 120, so that the first heat-affected zone is centrally symmetric about the center line of the heating panel 120. The electric heating module 300 can also be designed to have one or more regions that are centrally symmetric about the center line of the heating panel 120, so that the second heat-affected zone is centrally symmetric about the center line of the heating panel 120.

[0060] In this way, at least one of the first heat-affected zone and the second heat-affected zone is centrally symmetrical about the center line of the heating panel 120, so that the heat-affected zone is more evenly distributed on the heating panel 120, and the container placed in the center area of ​​the heating panel 120 can be heated. This symmetrical design ensures uniform heat distribution on the heating panel 120, avoiding local overheating or cold spot problems. In addition, the symmetrical arrangement of the heat-affected zones enables the heating device to better adapt to containers of different materials and shapes. Whether the container is round, square or other shapes, it can be effectively heated within the symmetrical heat-affected zones, improving the adaptability and flexibility of the heating device.

[0061] In a possible implementation, the magnetic thermal module 200 is centrally symmetrical about the center line of the heating panel 120 .

[0062] As such, the magnetocaloric module 200 is centrally symmetrical about the centerline of the heating panel 120, making the heating area of ​​the magnetocaloric module 200 more evenly distributed across the heating panel 120. Furthermore, the centrally symmetrical design of the magnetocaloric module 200 makes the structure of the heating panel 120 more balanced, reducing the uneven physical stress caused by asymmetric heating and improving the structural stability of the heating panel 120.

[0063] In a possible implementation, the magnetic thermal module 200 includes a plurality of submodules 210 , and the plurality of submodules 210 are distributed around a center line of the heating panel 120 .

[0064] For example, the magnetic thermal module 200 includes four submodules 210, each of which can function as an independent magnetic thermal unit. The four submodules 210 are arranged around the centerline of the heating panel 120, forming a symmetrical layout. Furthermore, to reduce the footprint of the heating panel 120 and optimize its spatial layout, the electric heating module 300 can be designed in a ring shape, thereby surrounding the periphery of the magnetic thermal module 200. Alternatively, the electric heating module 300 can be designed as a plurality of strip-shaped electric heating units, each of which can be arranged around the magnetic thermal unit.

[0065] In this way, the multiple submodules 210 are distributed around the center line of the heating panel 120, so that the electromagnetic heating area of ​​the magnetocaloric module 200 is more evenly distributed on the heating panel 120, further ensuring uniform heat distribution on the heating panel 120.

[0066] In a possible implementation, the electric heating module 300 is centrally symmetrical about the center line of the heating panel 120 .

[0067] In this way, the electric heating modules 300 are symmetrically distributed about the centerline of the heating panel 120. This ensures uniform heat distribution during heating. Furthermore, it allows the heat at the center of the heating panel 120 to be concentrated and evenly distributed. The electric heating modules 300 can heat a container placed in the center of the heating panel 120. Furthermore, the centrally symmetrical electric heating modules 300 make the structure of the heating panel 120 more balanced, reducing uneven physical stress caused by asymmetric heating and improving the structural stability of the heating panel 120.

[0068] In one possible implementation, refer to Figure 1 The electric heating module 300 includes a first part 310 and a second part 320 . The first part 310 is located in the central area of ​​the heating panel 120 . There are multiple second parts 320 , which are evenly spaced along the circumference of the first part 310 .

[0069] In a possible design, the electric heating module 300 may include four fan-shaped parts, one side of each fan-shaped part extends inward and contacts with the side of the other fan-shaped parts to form a rhombus-shaped first part 310 with a curved outer edge, that is, Figure 1 The dotted line in the figure is inward and is surrounded by the outer edge of the electric heating module 300. The outer edge of the first portion 310 can be semicircular to fit the magnetic thermal module 200. Further, the second portion 320 of the electric heating module 300 is the remaining portion of the electric heating module 300 except the first portion 310, i.e. Figure 1 The portion outside the dotted line. The distance between the two sides of each sector first decreases from large to small and then increases from small to large, forming a symmetrical structure.

[0070] In a possible design, the first portion 310 of the electric heating module 300 has a through hole in the middle for accommodating the container identification sensor 400 .

[0071] In this way, during electrical heating, the first portion 310 of the electric heating module 300 and the circumferentially distributed second portion 320 can simultaneously provide heat, ensuring a rapid response and efficient operation of the heating process. Furthermore, the design of the first portion 310 and the second portion 320 enables the heating device to better adapt to non-magnetic containers of various materials and shapes. Whether the container is circular, square, or another shape, more effective heating can be achieved within the heating area formed by the first portion 310 in the central area and the heating area formed by the circumferentially distributed second portion 320, thereby improving the adaptability and flexibility of the heating device.

[0072] In a possible implementation, the magnetic thermal module 200 includes a plurality of submodules 210 , and each submodule 210 is located between two adjacent second parts 320 .

[0073] For example, the magnetic thermal module 200 includes four submodules 210, each of which is located between two adjacent second portions 320. Each submodule 210 is circular, and a portion of its outer edge matches the outer edge of the first portion 310 of the electrothermal module 300.

[0074] In this way, the submodules 210 of the magnetic thermal module 200 are distributed between the two adjacent second parts 320 of the electric heating module 300, making the structure of the heating panel 120 more compact and reducing the occupied area of ​​the heating module, which not only saves space but also makes the overall layout of the heating device more reasonable.

[0075] In one possible implementation, the magnetocaloric module 200 includes a coil disk.

[0076] In one possible design, the coil disk can use copper wire, thereby reducing resistance loss and improving heating efficiency. The coil disk can be designed into a flat spiral shape to form a uniform magnetic field below the heating panel 120. The number of turns of the coil disk is designed based on the actual required heating power and frequency, and this application does not impose any restrictions. In this way, by arranging the coil disk within the magnetocaloric module 200, an alternating magnetic field can be generated, generating eddy currents at the bottom of the magnetic container, rapidly heating the magnetic container, and reaching the desired temperature in a short time, thereby improving heating efficiency.

[0077] In a possible implementation, the electric heating module 300 includes an electric heating coating, which is coated on a surface of the heating panel 120 facing the mounting cavity 130 .

[0078] In one possible design, the electrothermal coating can include materials such as aluminum oxide and silicon nitride. The coating thickness can range from 0.1 to 0.3 mm. Because the electrothermal coating has a high resistivity, the heat generated by the electrothermal module 300 can be directly and efficiently transferred to the heating panel 120, and then transferred to the bottom of the container through the heating panel 120.

[0079] Thus, the electric heating module 300 can cover a larger area by providing the electric heating coating, ensuring uniform heating of the entire heating panel 120. Furthermore, the electric heating coating is thinner and lighter than traditional electric heating elements (such as resistance wire), reducing the weight of the heating device and making it more portable.

[0080] In one possible implementation, refer to Figure 2 The heating device further includes a container identification sensor 400 disposed in the mounting cavity 130 , and the container identification sensor 400 is configured to identify the type of container disposed on the heating panel 120 , including a magnetic conductive container and a non-magnetic conductive container.

[0081] In one possible design, container identification sensor 400 may be a capacitive sensor. The capacitive sensor can determine the type of container by detecting changes in capacitance at the bottom of the container. Containers of different materials produce different capacitance values ​​near the capacitive sensor, which can be used to determine the container type.

[0082] It is understandable that the dielectric constant of a magnetically conductive container is relatively low. When a magnetically conductive container is placed above the container identification sensor 400, the capacitance between the container identification sensor 400 and the heating panel 120 will increase significantly due to the container's good conductivity. This is because the magnetically conductive container forms a large conductive surface, increasing the parallel plate effect of the capacitor. In contrast, the dielectric constant of a non-magnetic container is higher. When a non-magnetic container is placed above the container identification sensor 400, the capacitance between the capacitive sensor and the heating panel 120 will also increase due to the container's high dielectric constant, but the increase will be less than that of a magnetically conductive container. This is because, although the non-magnetic container does not form a conductive surface, its high dielectric constant increases the capacitance effect of the dielectric.

[0083] In another possible design, the container identification sensor 400 can also be an infrared sensor. The infrared sensor determines the type of container by detecting the infrared radiation characteristics of the container bottom. Containers of different materials have different infrared radiation characteristics, which can be used to determine the container type.

[0084] As you can understand, the basic principle of an infrared sensor is to detect infrared radiation emitted by an object. All objects emit infrared radiation depending on their temperature. Objects of different materials may emit infrared radiation with different intensities and wavelength distributions at the same temperature. Infrared sensors identify an object's material by detecting these differences.

[0085] The heating device also includes a control device 500 connected to the container identification sensor 400, the magnetic thermal module 200 and the electric heating module 300 respectively. The control device 500 is configured to control the operation of the magnetic thermal module 200 or the electric heating module 300 according to the identification result of the container identification sensor 400.

[0086] Thus, by providing a container recognition sensor 400, the type of container placed on the heating panel 120 can be automatically identified, including both magnetic and non-magnetic containers. This automatic recognition function reduces the number of user steps and improves the intelligence of the heating device. Furthermore, the control device 500 can automatically select the appropriate heating method based on the type of container. For magnetic containers, the magnetic heating module 200 is activated for electromagnetic heating; for non-magnetic containers, the electric heating module 300 is activated for heating, improving the efficiency of the heating process.
