Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and in particular relates to an electromagnetic cooking appliance. Background Art

[0002] In existing electromagnetic cooking utensils, the electromagnetic coil generates an induced magnetic field when powered on, causing the ferromagnetic pot to heat up by induction to cook food. Electromagnetic coil heating has the advantages of fast heat generation and high efficiency, so it is increasingly widely used. The shell of existing electromagnetic cooking utensils generally adopts a plastic shell or a metal shell, and the existing metal shell is basically made of ferromagnetic material. During the operation of the electromagnetic coil, the metal shell will be heated due to electromagnetic radiation, causing the temperature of the metal shell to rise, affecting the customer experience.

[0003] The prior art discloses a pot body of a cooking utensil, comprising a coil disk assembly, a metal shell, an inner pot and a magnetic isolation device, wherein the shell comprises an annular side wall, which surrounds the coil disk assembly and forms a gap with the coil disk assembly, the magnetic isolation device comprises a magnetic isolation sheet and a support plate, the distance between the magnetic isolation sheet and the annular side wall is preferably 5 mm, the support plate comprises a limiting groove and a plurality of protrusions are provided on its inner surface, the top of the magnetic isolation sheet is inserted into the limiting groove, and the magnetic isolation sheet is provided with a plurality of assembly holes, the protrusions extend into the assembly holes to fix the magnetic isolation sheet to the inner side of the support plate, and the assembled magnetic isolation sheet fits the inner surface of the support plate. The installation and fixing method of the magnetic isolation plate in this technical solution has the following defects: the installation of the magnetic isolation plate requires the aid of a support plate, and the two need to be assembled through an interference fit between the protrusions and the assembly holes. Not only are their respective structural designs complex and costly, but the assembly process is also complex and the production efficiency is low; the gap between the annular side wall and the coil disk assembly itself is relatively small, and space must be reserved for the setting of the support plate and the distance between the magnetic isolation plate and the annular side wall, which affects the space utilization of the cooking utensil. While meeting the requirements for the installation of the support plate and the distance between the magnetic isolation plate and the annular side wall, the volume of the entire pot body increases, which is not conducive to the miniaturization of the entire machine; when the gap size between the annular side wall and the coil disk assembly is fixed, the setting of the support plate results in a relatively small distance between the magnetic isolation plate and the coil disk assembly. During the operation of the cooking utensil, the magnetic isolation plate is prone to resonate under the action of the magnetic field force of the coil disk assembly, which not only causes noise but also easily causes the magnetic isolation plate to loosen, affecting the magnetic isolation effect. Utility Model Content

[0004] The present application provides an electromagnetic cooking utensil to solve the technical problem that the assembly process of the magnetic isolation plate of the existing electromagnetic cooking utensil is complicated and the distance between the magnetic isolation plate and the electromagnetic wire coil cannot be rationalized, which leads to an increased risk of resonance of the magnetic isolation plate under the action of magnetic field force.

[0005] The technical solution adopted in this application is:

[0006] An electromagnetic cooking utensil comprises a shell and an electromagnetic wire coil arranged in the shell, and also comprises a non-metal first wave-absorbing shielding member located between the shell and the electromagnetic wire coil, wherein the first wave-absorbing shielding member is glued and fixed to a side of the shell facing the electromagnetic wire coil.

[0007] The electromagnetic cooking appliance in this application also includes the following additional technical features:

[0008] The thickness of the first wave-absorbing shielding member is greater than the thickness of the housing.

[0009] The housing comprises a base and a metal side wall which is arranged above the base and surrounds the electromagnetic wire coil, and the first wave-absorbing shielding component is adhered and fixed to the inner wall surface of the metal side wall.

[0010] A plurality of the first wave-absorbing shielding members are arranged at intervals along the circumferential direction of the metal side wall.

[0011] The cross-section of the metal side wall along the horizontal direction is a non-circular structure, and the first wave-absorbing shielding component is located at the shortest distance between the inner wall surface of the metal side wall and the electromagnetic wire coil.

[0012] The bottom surface of the first wave-absorbing shielding component is located at a height higher than the bottom surface of the metal side wall.

[0013] The housing includes a base and a metal side wall disposed above the base and surrounding the electromagnetic wire reel. The first wave-absorbing shielding member is adhered and fixed to a side of the base facing the electromagnetic wire reel to shield radiation generated by the electromagnetic wire reel toward the outside of the base.

[0014] The thickness of the first wave-absorbing shielding component is 0.2 mm-1.5 mm.

[0015] The top surface of the first wave-absorbing shielding member is located at a height higher than the top of the electromagnetic wire reel.

[0016] A circuit board and a bracket for mounting the circuit board are also provided in the shell, the bracket extends vertically and is located between the electromagnetic wire reel and the shell, the circuit board is provided on the side of the bracket facing away from the electromagnetic wire reel, and a second wave-absorbing shielding component is adhered and fixed to the side of the bracket facing the electromagnetic wire reel, and the second wave-absorbing shielding component is a structure made of non-metallic material containing wave-absorbing components.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. The first wave-absorbing shielding member in the present application is glued and fixed on the side of the shell facing the electromagnetic wire coil. The glue-fixing method can save the need for fasteners and mechanical fixing structures, which not only helps to reduce costs, but also simplifies the assembly process and improves the assembly speed, thereby improving the overall production efficiency of the cooking utensil. Moreover, the glue-fixing method does not require additional space to accommodate fasteners and mechanical fixing structures, so the space inside the cooking utensil can be more effectively utilized to achieve rational use of space. On the one hand, it helps to miniaturize the entire cooking utensil, and on the other hand, it can optimize the distance between the first wave-absorbing shielding member and the electromagnetic wire coil, reduce the probability of resonance of the first wave-absorbing shielding member under the action of the magnetic field force, ensure the installation position of the first wave-absorbing shielding member, and thus ensure the magnetic isolation effect. Furthermore, the glue-fixing method can provide a strong fixing strength for the first wave-absorbing shielding member, avoiding resonance or loosening of the first wave-absorbing shielding member during the operation of the electromagnetic cooking utensil. In addition, the glue-fixing method helps to stick the first wave-absorbing shielding member tightly and evenly on the shell, thereby improving the magnetic isolation effect. The first wave-absorbing shielding component in the present application is a structure made of non-metallic material, which can better absorb and reduce the propagation of electromagnetic waves, and reduce the impact of electromagnetic radiation on the housing and other metal parts. Moreover, the first wave-absorbing shielding component is made of non-metallic material. During the operation of the cooking utensil, the first wave-absorbing shielding component itself will not be heated by the electromagnetic field, nor will it be affected by electromagnetic fields to produce high-frequency vibrations, which helps to ensure the magnetic isolation effect.

[0019] 2. As a preferred embodiment of the present application, the shell includes a base and a metal side wall located above the base. The first wave-absorbing shielding component is adhered and fixed to the inner wall surface of the metal side wall. The first wave-absorbing shielding component can shield the electromagnetic radiation of the electromagnetic wire reel, thereby avoiding the problem of the electromagnetic wire reel heating the metal side wall and causing the metal side wall temperature to be too high, thereby improving the user experience.

[0020] Furthermore, the cross-section of the metal side wall along the horizontal direction is a non-circular structure, so that the effective cooking capacity can be increased under the same volume of the cooking utensil, and the first wave-absorbing shielding component is located at the shortest distance between the inner wall surface of the metal side wall and the electromagnetic wire disk, so that the part of the metal side wall closest to the electromagnetic wire disk can be protected to avoid rapid temperature rise at this position. In addition, because the first wave-absorbing shielding component is fixed by pasting, when the first wave-absorbing shielding component is set at the shortest distance between the metal side wall and the electromagnetic wire disk, it can still ensure that the first wave-absorbing shielding component and the electromagnetic wire disk maintain a sufficient distance, reduce the probability of resonance of the first wave-absorbing shielding component under the action of the magnetic field force, thereby reducing the probability of loosening and position movement of the first wave-absorbing shielding component, thereby ensuring the magnetic isolation effect.

[0021] 3. As a preferred embodiment of the present application, the shell includes a base and a metal side wall located above the base. The first wave-absorbing shielding component is adhered and fixed to the side of the base facing the electromagnetic wire reel to shield the radiation generated by the electromagnetic wire reel to the outside of the base. When the electromagnetic cooking utensil is placed on a metal table top such as a kitchen or a dining table, the provision of the first wave-absorbing shielding component in this embodiment can prevent the metal table top from being heated during the operation of the electromagnetic cooking utensil, thereby protecting the metal table top, which not only extends the service life of the metal table top, but also prevents users from having a bad experience due to touching the metal table top.

[0022] 4. As a preferred embodiment of the present application, the thickness of the first absorbing shielding member 3 is 0.2 mm to 1.5 mm. This configuration can provide a certain degree of shielding effect and maintain the structural strength of the first absorbing shielding member 3, so that it remains stable in high temperature and vibration environments and improves its durability.

[0023] 5. As a preferred embodiment of the present application, a bracket is provided in the housing between the electromagnetic wire reel and the housing, a circuit board is provided on the side of the bracket facing away from the electromagnetic wire reel, and a second wave-absorbing shielding member is fixed on the side of the bracket facing the electromagnetic wire reel. The provision of the second wave-absorbing shielding member in this embodiment helps to reduce electromagnetic interference and protect the circuit board from the magnetic field interference of the electromagnetic wire reel, and also prevents the electromagnetic interference generated by the circuit board from the operation of other parts in the housing. In addition, the bracket extends vertically to be located between the electromagnetic wire reel and the housing, and the circuit board is located on the side of the bracket facing away from the electromagnetic wire reel, so that the circuit board can be separated from the electromagnetic wire reel by means of the bracket, which helps to achieve thermal insulation protection for the circuit board and prevent the circuit board from overheating, which not only prolongs the service life of the circuit board, but also helps the circuit board to work at a suitable temperature and improves its stability and reliability during operation. Moreover, the vertical extension of the bracket also realizes the vertical installation of the circuit board in a limited space, optimizes the space utilization, and makes the overall structure of the cooking utensil more compact.

[0039] like Figures 1 to 3 As shown, an electromagnetic cooking device includes a shell and an electromagnetic wire coil 5 arranged in the shell, and also includes a non-metallic first wave-absorbing shielding component 3 located between the shell and the electromagnetic wire coil 5. The first wave-absorbing shielding component 3 is glued and fixed to the side of the shell facing the electromagnetic wire coil 5.

[0040] The electromagnetic cooking utensils in the present application may be an induction cooker, an electromagnetic rice cooker, an electromagnetic pressure cooker, an electromagnetic stew pot, etc.

[0041] The first wave-absorbing shielding member 3 in the present application is glued and fixed on the side of the shell facing the electromagnetic wire coil 5. The glue-fixing method can save the need for fasteners and mechanical fixing structures, which not only helps to reduce costs, but also simplifies the assembly process and improves the assembly speed, thereby improving the overall production efficiency of the cooking utensil. Moreover, the glue-fixing method does not require additional space to accommodate fasteners and mechanical fixing structures, so the space inside the cooking utensil can be more effectively utilized to achieve rational use of space. On the one hand, it helps to miniaturize the entire cooking utensil, and on the other hand, it can optimize the distance between the first wave-absorbing shielding member 3 and the electromagnetic wire coil 5, reduce the probability of resonance of the first wave-absorbing shielding member 3 under the action of the magnetic field force, ensure the installation position of the first wave-absorbing shielding member 3, and thus ensure the magnetic isolation effect. Furthermore, the glue-fixing method can provide a strong fixing strength for the first wave-absorbing shielding member 3, avoiding resonance or loosening of the first wave-absorbing shielding member 3 during the operation of the electromagnetic cooking utensil. In addition, the glue-fixing method helps to stick the first wave-absorbing shielding member 3 tightly and evenly on the shell, thereby improving the magnetic isolation effect.

[0042] In the present application, the first wave-absorbing shielding component 3 is a structure made of a non-metallic material containing wave-absorbing components, which can better absorb and reduce the propagation of electromagnetic waves, and reduce the impact of electromagnetic radiation on the shell and other metal parts. Moreover, the first wave-absorbing shielding component 3 is made of non-metallic material. During the operation of the cooking utensil, the first wave-absorbing shielding component 3 itself will not be heated by the electromagnetic field, nor will it produce high-frequency vibration due to electromagnetic influence, which helps to ensure the magnetic isolation effect. The wave-absorbing material in the present application refers to a type of material that can absorb the electromagnetic wave energy projected onto its surface. It converts the incident electromagnetic wave into heat energy or other energy forms through various loss mechanisms of the material to achieve the purpose of absorbing electromagnetic waves. Moreover, the first wave-absorbing shielding component 3 in the present application has the properties of light weight, temperature resistance, moisture resistance, corrosion resistance, etc. Preferably, the main component of the first wave-absorbing shielding component 3 is a carbon-based wave-absorbing material, such as graphene, graphite, carbon black or carbon fiber.

[0043] As a preferred embodiment of the present application, Figure 2 As shown, the first absorbing shielding member 3 is glued and fixed to the inner wall surface of the shell, so that an adhesive layer 4 is formed between the first absorbing shielding member 3 and the inner wall surface of the shell.

[0044] In one embodiment, the thickness of the first absorbing shielding member 3 is greater than the thickness of the shell. The main function of the first absorbing shielding member 3 is to absorb electromagnetic waves. Its thickness is greater than the thickness of the shell, which can better absorb more electromagnetic waves and reduce the impact of electromagnetic radiation on the shell and other metal parts.

[0045] In the present application, the specific pasting and fixing position of the first wave-absorbing shielding member 3 on the inner wall of the housing can adopt any one of the following embodiments:

[0046] Implementation method 1: Figures 1 to 3 As shown, the housing includes a base 2 and a metal side wall 1 disposed above the base 2 and surrounding the electromagnetic wire drum 5, and a first wave-absorbing shielding member 3 is adhered and fixed to the inner wall surface of the metal side wall 1. The first wave-absorbing shielding member 3 can shield the electromagnetic radiation of the electromagnetic wire drum 5, avoid the electromagnetic wire drum 5 heating the metal side wall 1 and causing the metal side wall 1 to be overheated, and improve the user experience.

[0047] As a preferred embodiment of this implementation, Figure 3 As shown, a plurality of first wave-absorbing shielding members 3 are provided at intervals along the circumference of the metal side wall 1. By providing a plurality of first wave-absorbing shielding members 3, the shielding effect can be improved, the leakage of electromagnetic energy can be more effectively reduced, and the probability of the metal side wall 1 being heated and heated under the action of the electromagnetic field can be reduced. Moreover, by arranging a plurality of first wave-absorbing shielding members 3, the occurrence of local hot spots on the metal side wall 1 can be reduced, thereby reducing the phenomenon of excessive local temperature rise of the metal side wall 1 and extending the service life of the metal side wall 1.

[0048] As a preferred embodiment of this implementation, Figure 3 As shown, the cross-section of the metal side wall 1 along the horizontal direction is a non-circular structure, so that the effective cooking capacity can be increased under the same volume of the cooking utensil. The first wave-absorbing shielding component 3 is located at the shortest distance between the inner wall surface of the metal side wall 1 and the electromagnetic wire coil 5, so that the part of the metal side wall 1 closest to the electromagnetic wire coil 5 can be protected to avoid rapid temperature rise at this position. Moreover, because the first wave-absorbing shielding component 3 is fixed by pasting, when the first wave-absorbing shielding component 3 is set at the shortest distance between the metal side wall 1 and the electromagnetic wire coil 5, it can still ensure that the first wave-absorbing shielding component 3 and the electromagnetic wire coil 5 maintain a sufficient distance, reduce the probability of resonance of the first wave-absorbing shielding component 3 under the action of the magnetic field force, thereby reducing the probability of loosening and position movement of the first wave-absorbing shielding component 3, thereby ensuring the magnetic isolation effect.

[0049] In a specific example, Figure 3 As shown, the cross-section of the metal side wall 1 along the horizontal direction is designed to be an oblong, and the first wave-absorbing shielding component 3 is respectively adhered and fixed on the two opposite side walls of the metal side wall 1, and the fixed position of the first wave-absorbing shielding component 3 on the metal side wall 1 is closest to the electromagnetic wire reel 5 compared with other positions of the metal side wall 1.

[0050] The extension position of the bottom of the first wave-absorbing shielding member 3 in the first embodiment can be any one of the following embodiments:

[0051] Embodiment 1: The bottom surface of the first absorbing shielding member 3 is located at a height lower than the bottom surface of the metal side wall 1. That is, in this embodiment 1, the bottom surface of the first absorbing shielding member 3 extends downward to below the bottom surface of the metal side wall 1, and the first absorbing shielding member 3 located below the metal side wall 1 can be suspended or connected to the inner wall surface of the base 2 by bonding.

[0052] Embodiment 2: as Figure 1 and Figure 2 As shown, the height of the bottom surface of the first wave absorbing shielding member 3 is higher than the height of the bottom surface of the metal side wall 1, or the height of the bottom surface of the first wave absorbing shielding member 3 is substantially flush with the height of the bottom surface of the metal side wall 1. Preferably, the height of the bottom surface of the first wave absorbing shielding member 3 is slightly higher than the height of the bottom surface of the metal side wall 1, which can, on the one hand, enable the first wave absorbing shielding member 3 to shield electromagnetic leakage as much as possible, and on the other hand, enable the covering position of the first wave absorbing shielding member 3 to avoid the joint surface between the metal side wall 1 and the base 2, thereby ensuring the stable installation of the first wave absorbing shielding member 3, improving the fixing strength of the first wave absorbing shielding member 3, and preventing the first wave absorbing shielding member 3 from loosening during the operation of the electromagnetic cooking device.

[0053] Embodiment 2: The housing includes a base 2 and a side wall disposed above the base 2 and arranged around the electromagnetic wire coil 5. The first wave-absorbing shielding member 3 is adhered and fixed to the side of the base 2 facing the electromagnetic wire coil 5 to shield the radiation generated by the electromagnetic wire coil 5 to the outside of the base 2. In this embodiment 2, the material of the side wall arranged around the electromagnetic wire coil 5 can be metal or plastic. When the electromagnetic cooking utensil is placed on a metal tabletop such as a kitchen or a dining table, the provision of the first wave-absorbing shielding member 3 in this embodiment 2 can prevent the metal tabletop from being heated during the operation of the electromagnetic cooking utensil, thereby protecting the metal tabletop, which not only prolongs the service life of the metal tabletop, but also prevents the user from having a bad experience due to touching the metal tabletop.

[0054] Embodiment 3: The housing includes a base 2 and a metal side wall 1 disposed above the base 2 and arranged around the electromagnetic wire coil 5. The inner wall surface of the metal side wall 1 is fixedly bonded with a first wave-absorbing shielding member 3, and the side of the base 2 facing the electromagnetic wire coil 5 is also fixedly bonded with a first wave-absorbing shielding member 3. The provision of the first wave-absorbing shielding member 3 in this embodiment can not only produce a certain protective effect on the metal side wall 1 to prevent the metal side wall 1 from heating up under electromagnetic action, but also produce a certain protective effect on the metal tabletop carrying the electromagnetic cooking utensils to prevent the metal tabletop from heating up under electromagnetic action.

[0055] As a preferred embodiment of the present application, the thickness of the first absorbing shielding member 3 is 0.2 mm-1.5 mm. Such a configuration can provide a certain degree of shielding effect and maintain the structural strength of the first absorbing shielding member 3, so that it remains stable in high temperature and vibration environments and improves its durability.

[0056] In one embodiment, the top surface of the first absorbing shielding member 3 is flush with the top of the electromagnetic wire drum 5 , or the top surface of the first absorbing shielding member 3 is slightly lower than the top of the electromagnetic wire drum 5 .

[0057] In another embodiment, if Figure 2 As shown, the top surface of the first wave absorbing shielding member 3 is located at a height higher than the top of the electromagnetic wire drum 5. According to the distribution of magnetic lines of force, the top surface of the first wave absorbing shielding member 3 is set to be higher than the top of the electromagnetic wire drum 5, which can shield the leakage of electromagnetic waves to the maximum extent and improve the protection effect of the first wave absorbing shielding member 3 on the metal side wall 1.

[0058] As a preferred embodiment of the present application, a circuit board and a bracket for mounting the circuit board are also provided in the housing, the bracket extends vertically and is located between the electromagnetic wire reel 5 and the housing, the circuit board is provided on the side of the bracket facing away from the electromagnetic wire reel 5, and a second wave-absorbing shielding member is pasted and fixed on the side of the bracket facing the electromagnetic wire reel 5. The provision of the second wave-absorbing shielding member in this embodiment helps to reduce electromagnetic interference, protect the circuit board from the magnetic field interference of the electromagnetic wire reel 5, and also prevent the electromagnetic interference generated by the circuit board from the operation of other parts in the housing. In addition, the bracket extends vertically to be located between the electromagnetic wire reel 5 and the housing, and the circuit board is located on the side of the bracket facing away from the electromagnetic wire reel 5, so that the circuit board can be separated from the electromagnetic wire reel 5 by means of the bracket, which helps to achieve thermal insulation protection for the circuit board and prevent the circuit board from overheating, which not only prolongs the service life of the circuit board, but also helps the circuit board to work at a suitable temperature and improves its stability and reliability during operation. Moreover, the vertical extension of the bracket also realizes the vertical installation of the circuit board in a limited space, optimizes the space utilization, and makes the overall structure of the cooking utensil more compact.

[0059] Furthermore, the second absorbing shielding member is a structure made of a non-metallic material containing absorbing components. Preferably, in this embodiment, the main component of the first absorbing shielding member 3 is a carbon-based absorbing material, such as graphene, graphite, carbon black or carbon fiber.
