Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and more specifically, to a cooking utensil. Background Technology

[0002] In related technologies, with the continuous development of modern kitchen appliance technology, electromagnetic heating (IH heating) technology has become an indispensable part of cooking appliances such as electric pressure cookers, rice cookers, and induction cookers due to its efficient, fast, and precise heating characteristics.

[0003] In existing IH heating cooking appliances, the coils are usually arranged to form a ring-shaped high-temperature heating zone on the inner pot. While this ring-shaped high-temperature zone can promote the rapid boiling of liquids within the zone and create a certain degree of thermal convection, allowing food to tumble more thoroughly in this area, food located outside this ring-shaped high-temperature zone experiences reduced heating efficiency and a slower temperature rise. This results in reduced tumbling of food in these areas, and the food may even settle at the bottom of the pot, making it difficult to tumble. Ultimately, this leads to inconsistent cooking times, affecting the overall taste and cooking effect of the food. Utility Model Content

[0004] The main purpose of this invention is to provide a cooking appliance to solve the problem in related technologies where the food is not tumbled enough, thus affecting the overall taste of the food.

[0005] To achieve the above objectives, this utility model provides a cooking appliance, comprising: a coil base; an IH coil mounted on the coil base; an inner pot positioned above the coil base and the IH coil and capable of heating under the magnetic field of the IH coil; a magnetic shielding component positioned between the IH coil and the inner pot, the magnetic shielding component having a magnetic overpass area and a magnetic shielding area; and a magnetic focusing component positioned below the IH coil and corresponding to the magnetic overpass area.

[0006] By applying the technical solution of this utility model, a magnetic shielding component is disposed between the inner pot and the IH coil. The magnetic shielding component has a magnetically permeable region and a magnetically shielding region. The magnetic field generated by the IH coil can smoothly pass through the magnetically permeable region and act on the inner pot, creating a strong heating area at the position corresponding to the magnetically permeable region on the inner pot. The magnetic field generated by the IH coil is blocked by the magnetically shielding region, resulting in no or only a small number of magnetic field lines acting on the position corresponding to the magnetically shielding region on the inner pot, creating a weak heating area. Thermal convection can then occur from the strong heating area to the weak heating area within the inner pot, increasing the degree of tumbling of the food. Furthermore, the cooking appliance also includes a magnetic focusing component disposed below the IH coil and corresponding to the magnetically permeable region. The magnetic focusing component enhances the magnetic field acting on the inner pot through the magnetically permeable region, further increasing the temperature of the strong heating area on the inner pot, increasing the temperature difference between the strong and weak heating areas, and thus creating stronger thermal convection, allowing the food in the inner pot to tumble fully. Therefore, the technical solution of this application can effectively solve the problem in related technologies where the degree of tumbling of some foods is low, affecting the overall taste of the food.

[0007] Furthermore, the magnetic shielding component has multiple magnetic transmission areas and multiple magnetic shielding areas. In the circumferential direction of the inner pot, a magnetic transmission area is provided between every two adjacent magnetic shielding areas. Multiple magnetic focusing components are present, each corresponding to one of the multiple magnetic transmission areas. Through this arrangement, multiple alternating strong heating areas and multiple weak heating areas are formed on the inner pot in the circumferential direction, enabling multiple streams of heat convection within the inner pot. This further increases the tumbling degree of the food within the inner pot and ensures that all food within the inner pot can tumble fully.

[0008] Furthermore, the magnetic shielding component includes a hollow portion located within the magnetic transmission area and a magnetic shielding plate located within the magnetic shielding area. By forming the magnetic transmission area by setting a hollow portion on the magnetic shielding component, the processing cost of the magnetic shielding component is reduced and the processing technology of the magnetic shielding component is simplified while achieving partial magnetic shielding effect.

[0009] Furthermore, the magnetic shielding component includes a magnetic plate located within the magnetic transmission area and a magnetic shielding plate located within the magnetic shielding area. By placing a magnetic plate at a location on the magnetic shielding component where no magnetic shielding plate would normally be provided, the magnetic shielding component can form a complete disc-shaped structure or curved surface structure, preventing the corner structures on the magnetic shielding plate from being directly exposed and scratching assembly personnel.

[0010] Furthermore, the magnetic shielding component is made of a non-magnetic conductive material and includes a conductive ring connected to the magnetic shielding plate, the conductive ring surrounding the outer circumference of the inner pot; alternatively, the magnetic shielding component also includes a conductive ring connected to the outer or inner end of the magnetic shielding plate, the conductive ring surrounding the outer circumference of the inner pot, with the projection of the conductive ring on the coil base outside the projection range of the IH coil on the coil base. The magnetic shielding component made of a non-magnetic conductive material generates eddy currents on its surface under the influence of the magnetic field generated by the IH coil. These eddy currents can generate a magnetic field opposite to the magnetic field of the IH coil, thereby weakening or even canceling the original magnetic field, achieving the magnetic shielding effect. Furthermore, due to its good conductivity, the heat generated by the magnetic shielding component under the influence of the magnetic field is relatively low, preventing the magnetic shielding component from melting or damaging its mounting structure. Positioning the conductive ring outside the projection range of the IH coil on the coil base allows the conductive ring to be as far away from the IH coil as possible, weakening or preventing the magnetic field generated by the IH coil from acting on the conductive ring, thus reducing the overall heat generation of the magnetic shielding component.

[0011] Furthermore, the IH coil is installed below the wire reel base, and the magnetic shielding component is installed above the wire reel base. The IH coil, installed below the wire reel base and shielded by it, is protected. The magnetic shielding component, installed above the wire reel base, separates the IH coil from the magnetic shielding component, preventing the corner structure on the magnetic shielding component from scratching the protective adhesive layer of the IH coil and causing a risk of leakage.

[0012] Furthermore, the cooking appliance also includes a cover plate placed over the coil base and the magnetic shield. The cover plate can shield the coil base and the magnetic shield, preventing dust, food residue, and other dirt from falling directly onto the coil base and the magnetic shield, thus avoiding difficulties for the user in cleaning.

[0013] Furthermore, the cover is transparent; or, the cover is made of at least one material selected from plastic, ceramic, and glass. By making the cover transparent, the user can see the magnetic shielding component underneath, thus allowing the user to visually perceive the structural changes in the cooking appliance. The aforementioned materials are readily available and easy to process. In addition, these materials are easier to process into a smooth upper surface, making it convenient for users to clean dust, food residue, and other dirt that falls on it.

[0014] Furthermore, the IH coil is installed below the coil base, and the magnetic shielding component is installed between the coil base and the IH coil. Installing the magnetic shielding component below the coil base and positioning it between the coil base and the IH coil achieves partial magnetic shielding while also protecting the magnetic shielding component from dust, food residue, and other dirt that would be difficult to clean.

[0015] Furthermore, the magnetic shielding element is set on the outer surface of the inner pot. By directly setting the magnetic shielding element on the outer surface of the inner pot, the distribution of strong heating areas and weak heating areas on the inner pot can be controlled more precisely, forming effective heat convection and ensuring the food is heated evenly.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0043] like Figures 1 to 6 As shown, this application provides a cooking appliance, including: a coil base 10, an IH coil 20, an inner pot 30, a magnetic shielding component 40, and a magnetic focusing component 50. The IH coil 20 is mounted on the coil base 10; the inner pot 30 is positioned above the coil base 10 and the IH coil 20 and is capable of heating under the magnetic field of the IH coil 20; the magnetic shielding component 40 is positioned between the IH coil 20 and the inner pot 30, and the magnetic shielding component 40 has a magnetic overpass region 401 and a magnetic shielding region 402; the magnetic focusing component 50 is positioned below the IH coil 20 and is correspondingly positioned to the magnetic overpass region 401.

[0044] Using the technical solution of this application, the magnetic shielding component 40 is disposed between the inner pot 30 and the IH coil 20. The magnetic shielding component 40 has a magnetic overpass region 401 and a magnetic shielding region 402. The magnetic field generated by the IH coil 20 can pass smoothly through the magnetic overpass region 401 and act on the inner pot 30, so that a strong heating region 301 is formed on the inner pot 30 at the position corresponding to the magnetic overpass region 401. The magnetic field generated by the IH coil 20 is blocked by the magnetic shielding region 402, so that no or only a small number of magnetic field lines can act on the position on the inner pot 30 corresponding to the magnetic shielding region 402. A weak heating region 302 is formed on the inner pot 30 at the position corresponding to the magnetic shielding region 402. Heat convection from the strong heating region 301 to the weak heating region 302 can be formed in the inner pot 30 to increase the degree of tumbling of the food in the inner pot 30. Furthermore, the cooking appliance also includes a magnetic focusing element 50 disposed below the IH coil 20 and corresponding to the magnetic field passing through the magnetic field region 401. The magnetic focusing element 50 enhances the magnetic field acting on the inner pot 30 through the magnetic field passing through the magnetic field region 401, further increasing the temperature of the strong heating region 301 on the inner pot 30, increasing the temperature difference between the strong heating region 301 and the weak heating region 302, thereby forming stronger heat convection and allowing the food inside the inner pot 30 to tumble fully. Therefore, the technical solution of this application can effectively solve the problem in related technologies where the degree of tumbling of some foods is low, affecting the overall taste of the food.

[0045] like Figure 2 and Figure 4 As shown, in some embodiments, the magnetic focusing element 50 is a magnetic strip mounted below the IH coil 20 via a mounting bracket 70. As a magnetic material, the magnetic strip guides the magnetic field lines of the IH coil 20, pushing them towards the bottom of the inner pot 30 above, making the magnetic field more concentrated and directional, further increasing the magnetic field strength of the high-heating area 301. The mounting bracket 70 has a mounting groove and a buckle at the opening of the mounting groove. The magnetic strip is installed in the mounting groove and fixed to the mounting bracket 70 by the buckle.

[0046] like Figure 5 and Figure 6 As shown, the magnetic shielding component 40 has multiple magnetic transmission areas 401 and multiple magnetic shielding areas 402. In the circumferential direction of the inner pot 30, a magnetic transmission area 401 is provided between every two adjacent magnetic shielding areas 402. Multiple magnetic focusing components 50 are provided, each corresponding to one of the multiple magnetic transmission areas 401. This arrangement results in multiple alternating strong heating areas 301 and multiple weak heating areas 302 along the circumferential direction on the inner pot 30, enabling multiple heat convection currents to form within the inner pot 30. This further increases the tumbling degree of the food within the inner pot 30, ensuring that all food within the inner pot 30 can tumble sufficiently.

[0047] It should be noted that the aforementioned "multiple strong heating areas 301 and multiple weak heating areas 302 alternately arranged along the circumferential direction" means that, in the circumferential direction of the inner pot 30, there is a weak heating area 302 between every two adjacent strong heating areas 301, and a strong heating area 301 between every two adjacent weak heating areas 302. The term "multiple" refers to two or more.

[0048] like Figure 1 , Figure 5 , Figure 7 and Figure 9 As shown, the magnetic shielding component 40 includes a hollow portion 41 located within the magnetic transmission region 401 and a magnetic shielding plate 42 located within the magnetic shielding region 402. The magnetic shielding plate 42 blocks the magnetic field, while the hollow portion 41 allows the magnetic field to pass through smoothly. By providing the hollow portion 41 on the magnetic shielding component 40 to form the magnetic transmission region 401, the processing cost of the magnetic shielding component 40 is reduced and the processing technology of the magnetic shielding component 40 is simplified while achieving partial magnetic shielding.

[0049] like Figure 7 and Figure 8 As shown, in some embodiments, the magnetic shielding component 40 may be composed of multiple independently arranged magnetic shielding plates 42. These plates are spaced apart in the circumferential direction of the inner pot 30, forming multiple weak heating regions 302 independent of each other along the circumferential direction of the inner pot 30. The empty areas between the multiple magnetic shielding plates 42 form strong heating regions 301. The multiple independent magnetic shielding plates 42 may be disposed at the bottom of the inner pot 30, on the upper surface of the coil base 10, or below the coil base 10 and located between the coil base 10 and the IH coil 20.

[0050] like Figure 10 and Figure 11 As shown, the magnetic shielding component 40 includes a magnetic plate 43 located in the magnetic transmission region 401 and a magnetic shielding plate 42 located in the magnetic shielding region 402. The magnetic plate 42 blocks the magnetic field, while the magnetic plate 43 allows the magnetic field to pass through smoothly. By placing the magnetic plate 43 at a location on the magnetic shielding component 40 where the magnetic plate 42 would not be, the magnetic shielding component 40 can form a complete disc-shaped structure or curved surface structure, preventing the corner structures on the magnetic plate 42 from being directly exposed and scratching assembly personnel.

[0051] The magnetic plate 43 can be made of a material that does not produce any effect on the magnetic field or a material that has a magnetic focusing effect.

[0052] like Figure 5 as well as Figures 9 to 11As shown, the magnetic shielding component 40 is made of a non-magnetic conductive material. The magnetic shielding component 40 also includes a conductive ring 44 connected to the magnetic shielding plate 42, which surrounds the outer periphery of the inner pot 30. The non-magnetic conductive material has good conductivity. When the magnetic shielding component 40, made of a non-magnetic conductive material, is subjected to the magnetic field generated by the IH coil 20, eddy currents will be generated on its surface. These eddy currents can generate a magnetic field opposite to the magnetic field of the IH coil 20, thereby weakening or even canceling the original magnetic field, achieving the magnetic shielding effect. Furthermore, due to its good conductivity, the heat generated by the magnetic shielding component 40 under the influence of the magnetic field is relatively low, preventing the magnetic shielding component 40 from melting or damaging its mounting structure. The conductive ring 44 connects multiple magnetic shielding plates 42, enabling the magnetic shielding component 40 to generate eddy currents when subjected to the magnetic field of the IH coil 20. Figure 5 The circular current indicated by the arrow in the middle ensures that the magnetic field generated by the current in the magnetic shielding component 40 is opposite to the magnetic field direction of the IH coil 20, so as to ensure the magnetic shielding effect of the magnetic shielding component 40.

[0053] like Figure 3 , Figure 5 as well as Figures 9 to 11 As shown, the magnetic shielding component 40 also includes a conductive ring 44 connected to the outer or inner end of the magnetic shielding plate 42. The conductive ring 44 is arranged around the outer periphery of the inner pot 30, and the projection of the conductive ring 44 on the coil base 10 is outside the range of the projection of the IH coil 20 on the coil base 10. By ensuring that the projection of the conductive ring 44 on the coil base 10 is outside the range of the projection of the IH coil 20 on the coil base 10, the conductive ring 44 can be kept as far away from the IH coil 20 as possible, thereby weakening or avoiding the magnetic field generated by the IH coil 20 acting on the conductive ring 44. This reduces the overall heat generation of the magnetic shielding component 40 and also prevents the magnetic field generated by the conductive ring 44 from canceling out part of the magnetic field generated by the IH coil 20, thus weakening the magnetic field acting on the inner pot 30 and ensuring heating efficiency.

[0054] It should be noted that the above-mentioned "the projection of the conduction ring 44 on the coil base 10 is outside the range of the projection of the IH coil 20 on the coil base 10" means that the projection of the conduction ring 44 along the normal direction of the upper surface of the coil base 10 onto the upper surface of the coil base 10 is outside the range of the projection of the IH coil 20 along the normal direction of the upper surface of the coil base 10 onto the upper surface of the coil base 10.

[0055] Specifically, the aforementioned "non-magnetic conductive material" can be one or more of the following: aluminum, zinc, lead, tungsten, titanium, silver, gold, copper, etc.

[0056] like Figure 9 and Figure 11 As shown, in some embodiments, the conductive ring 44 is connected to the inner end of a plurality of magnetic shielding plates 42; as Figure 5 and Figure 10As shown, in some embodiments, the conductive ring 44 is connected to the outer ends of the plurality of magnetic shielding plates 42. Of course, in embodiments not shown in the figure, the conductive ring may also be connected to the middle of the plurality of magnetic shielding plates.

[0057] like Figure 1 and Figure 12 As shown, the IH coil 20 is installed below the coil base 10, and the magnetic shielding component 40 is installed above the coil base 10. The IH coil 20 is installed below the coil base 10 and can be shielded by it, protecting the IH coil 20 and preventing the user from directly seeing it. The magnetic shielding component 40 is installed above the coil base 10, separating the IH coil 20 from the magnetic shielding component 40, preventing the corner structure on the magnetic shielding component 40 from scratching the protective adhesive layer of the IH coil 20 and causing a risk of leakage.

[0058] Among them, IH coil 20 is enameled wire.

[0059] like Figure 15 As shown, for a cooking appliance where the magnetic shielding element 40 is installed above the coil base 10, the cooking appliance also includes a cover plate 60 covering the coil base 10 and the magnetic shielding element 40. The cover plate 60 can shield the coil base 10 and the magnetic shielding element 40, preventing dust and food residue from falling directly onto the coil base 10 and the magnetic shielding element 40, thus avoiding difficulties for the user in cleaning. At the same time, it can also prevent water, soup, and other liquids from flowing onto the surface of the magnetic shielding element 40, slowing down the oxidation rate of the surface of the magnetic shielding element 40.

[0060] Preferably, the cover plate 60 is a transparent part. By making the cover plate 60 a transparent part, the user can see the magnetic shielding part 40 underneath it, thereby allowing the user to intuitively perceive the structural changes of the cooking appliance.

[0061] Preferably, the cover plate 60 is made of at least one material selected from plastic, ceramic, and glass. Using non-metallic materials such as plastic, ceramic, and glass to make the cover plate 60 has the advantages of easy availability and processing. In addition, these materials are easier to process into a smooth upper surface, making it convenient for users to clean dust, food residue, and other dirt that falls on it.

[0062] like Figure 13 and Figure 14As shown, in some embodiments, the IH coil 20 is installed below the coil base 10, and the magnetic shielding component 40 is installed between the coil base 10 and the IH coil 20. Installing the magnetic shielding component 40 below the coil base 10 and positioning it between the coil base 10 and the IH coil 20 achieves partial magnetic shielding while also protecting the magnetic shielding component 40 from dust, food residue, and other dirt that are difficult to clean. Furthermore, since the magnetic shielding component 40 is placed in a position where it is not visible to the user, the precision requirements for its processing are relatively lower, thus reducing processing costs.

[0063] For the magnetic shielding component 40 installed on the wire tray 10, the connection between the wire tray 10 and the magnetic shielding component 40 can be achieved by locking with locking components, snapping with snapping components, or pre-embedding the magnetic shielding component 40 during injection molding.

[0064] like Figure 7 As shown, in some embodiments, the magnetic shielding element 40 is disposed on the outer surface of the inner pot 30. By directly disposing of the magnetic shielding element 40 on the outer surface of the inner pot 30, the distribution of the strong heating area 301 and the weak heating area 302 on the inner pot 30 can be controlled more precisely, forming effective heat convection and ensuring uniform heating of the food.

[0065] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0066] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0067] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0068] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
