[0002] Cooking appliances such as induction cookers are widely used in people's daily lives to cook food. The working principle of induction cookers is the electromagnetic induction phenomenon, that is, the alternating current passes through the coil disk to generate countless closed magnetic field forces. The magnetic lines of force cut through the pot to generate countless small eddy currents, causing the pot placed on the panel to heat up.

[0003] During the heating process, it is often necessary to detect the temperature of the pot. In the related art, wireless transmission modules are generally provided in the pot and the induction cooker respectively. After the NTC (Negative Temperature CoeffiCient) on the pot measures the temperature coefficient, it transmits the temperature to the induction cooker through the wireless transmission module after processing. After receiving the temperature signal, the wireless transmission module on the induction cooker transmits the temperature signal to the control module in the induction cooker. The control module adjusts the heating power of the induction cooker according to the temperature information.

[0004] However, the wireless transmission module in the induction cooker is susceptible to magnetic field interference from the coil disk, and the accuracy of signal transmission of the wireless transmission module is low. Utility Model Content

[0067] Induction cookers, electric ceramic cookers, electric pressure cookers, etc. are commonly used cooking appliances. Cookers include a shell and a panel. The shell includes an upper cover and a lower cover. The shell and the panel enclose a cavity for assembling a coil disk and a circuit board. The circuit board is electrically connected to the coil disk, and the circuit board is used to control the opening and closing of the coil disk. When working, a high-frequency current is passed through the coil disk, thereby generating countless closed magnetic field forces. The magnetic lines of force cut the pot to generate countless small eddy currents, causing the pot placed on the panel to heat up.

[0068] During the heating process, it is often necessary to detect the temperature of the pot, so as to adjust the working state of the induction cooker according to the temperature of the pot. Existing induction cookers only rely on the temperature sensor on the stove surface. Because the heat passes through multiple components on the heat conduction path, the intermediate heat conduction components are suspended, the interface thermal resistance is large, the thermal conductivity is low, and the heating area and the collection area are misaligned, there are often large temperature hysteresis and accuracy deviations.

[0069] Therefore, in the related art, wireless transmission modules are generally provided in the cooker and the induction cooker respectively. After the NTC (Negative Temperature CoeffiCient) on the cooker measures the temperature coefficient, it is processed (for example, a circuit board is provided inside the handle of the cooker, and the circuit board has a processing module) and the temperature is transmitted to the induction cooker through the wireless transmission module. After receiving the temperature signal, the wireless transmission module on the induction cooker transmits the temperature signal to the control module in the induction cooker, and the control module adjusts the heating power of the induction cooker according to the temperature information. However, in the related art, since the wireless transmission module in the induction cooker is close to the coil disk and its strong magnetic field area, the signal transmission is greatly interfered by the strong magnetic field, which is not conducive to protecting the wireless transmission module and affects the transmission accuracy of the signal of the wireless transmission module.

[0070] Based on the above technical problems, the embodiment of the present application provides a cooker and a cooking utensil, wherein the cooker includes an electromagnetic heating element, a first wireless component and an electromagnetic shielding element, wherein the electromagnetic heating element and the first wireless component are arranged at intervals, and at least part of the electromagnetic shielding element is located on a side of the first wireless component close to the electromagnetic heating element. In this way, the electromagnetic shielding element can protect the first wireless component from magnetic field interference of the electromagnetic heating element, and effectively improve the accuracy of signal transmission of the first wireless component.

[0071] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution 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 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 creative work are within the scope of protection of this application.

[0072] Reference Figures 1 to 3 As shown, the embodiment of the present application provides a cooking utensil 200, including a pot 210 and a cooker 100. The cooker 100 includes but is not limited to an induction cooker and an electric ceramic cooker. In this embodiment, the induction cooker is mainly used as an example for description.

[0073] It should be noted that the pot 210 and the cooker 100 of this embodiment are two detachable parts, wherein the cooker 100 and the pot 210 can be used together, for example, when cooking is required, the pot 210 is placed on the panel 110 of the cooker 100, and then the food in the pot 210 is cooked; or the cooker 100 can also be used as a conventional induction cooker. This embodiment does not limit this.

[0074] Reference Figure 3 As shown, the cooker 100 may be provided with a first wireless component 150, and the pot 210 may be provided with a second wireless component 220, and the second wireless component 220 is electrically connected to the first wireless component 150. Exemplarily, the first wireless component 150 and the second wireless component 220 may be electrically connected wirelessly. Exemplarily, the first wireless component 150 and the second wireless component 220 may be electromagnetic coils, and the first wireless component 150 and the second wireless component 220 are electromagnetically coupled.

[0075] It should be noted that during the cooking process, the entire power supply is provided by the power cord on the cooker 100, which is connected to an external power supply. The cooker 210 is not connected to a power cord, and the power supply of the cooker 210 is mainly provided by the electromagnetic coupling between the first wireless component 150 and the second wireless component 220. In addition to supplying power to the cooker 210, the first wireless component 150 and the second wireless component 220 also transmit the temperature signal of the cooker 210. Specifically, after the NTC (Negative Temperature CoeffiCient, negative temperature coefficient thermistor) on the cooker 210 measures the temperature coefficient, it is processed (for example, a circuit board is provided inside the cooker handle, and the circuit board has a processing module) and then the temperature is transmitted to the induction cooker through the second wireless component 220. After receiving the temperature signal, the first wireless component 150 on the induction cooker transmits the temperature signal to the control module in the induction cooker, and the control module adjusts the heating power of the induction cooker according to the temperature information.

[0076] Reference Figures 1 to 3 As shown, the cooker 100 includes a panel 110 and a housing 120, wherein the panel 110 covers the housing 120 and encloses a cavity 122 with the housing 120. The cavity 122 can be used to accommodate various electrical components such as a control board 130, a circuit board 170, a heating element, and a heat dissipation fan 190. The heat dissipation fan 190 is used to dissipate heat from the control board 130, the circuit board 170 and the heating element in the cavity 122, and the induction cooker is electrically connected to an external power source through a power cord.

[0077] Among them, the material of the shell 120 can be polypropylene (PP), polybutylene terephthalate (PBT), polyester resin (PET), nylon 6 (PA6), nylon 66 (PA66) or polyphenylene sulfide (PPS) with a temperature resistance greater than 125 degrees, or the material of the shell 120 can be PP, PBT, PET, PA6, PA66 or PPS plus glass fiber.

[0078] The panel 110 may be made of a high temperature resistant non-metallic material, such as a borosilicate glass panel, a ceramic panel, and a microcrystalline glass panel. When the cooking utensil is an induction cooker, the heating element is a coil disk, and the coil disk includes a coil disk support and a coil wound on the coil disk support; when the cooking utensil is an electric ceramic stove, the heating element may be formed by winding a resistance heating wire. In this embodiment, the heating element is mainly described as a coil disk as an example.

[0079] It should be noted that, since the induction cooker utilizes electromagnetic induction to heat the cookware, the heating element in this embodiment is mainly the electromagnetic heating element 140 .

[0080] Reference Figure 2 and Figure 3 As shown, the cooker 100 may include a panel 110 and a housing 120, the housing 120 includes an upper housing 123 and a lower housing 124, the upper housing 123 covers the lower housing 124, and forms a cavity 122 with the lower housing 124, an opening 125 is provided on a side of the upper housing 123 away from the lower housing 124, and the panel 110 covers the opening 125. It can be understood that the lower housing 124 is a cavity structure, the upper housing 123 is a frame structure, and the upper housing 123 covers the top edge of the lower housing 124.

[0081] The electromagnetic heating element 140 and the first wireless component 150 are arranged in the cavity 122, and the electromagnetic heating element 140 is arranged below the panel 110. In this way, it is ensured that the magnetic lines of force pass through the panel 110 to cut the pot to generate countless small eddy currents, thereby heating the pot 210 placed on the panel 110.

[0082] In order to effectively prevent the electromagnetic heating element 140 from generating magnetic field interference to the first wireless component 150 during the heating process, in the embodiment of the present application, an electromagnetic shielding element 160 is further provided in the cavity 122, and the electromagnetic shielding element 160 is spaced apart from the first wireless component 150 on the upper shell 123, and at least part of the electromagnetic shielding element 160 is located on a side of the first wireless component 150 close to the electromagnetic heating element 140.

[0083] It should be noted that, in the present embodiment, the electromagnetic shielding member 160 and the first wireless component 150 are arranged on the upper shell 123, so that the distance between the first wireless component 150 and the second wireless component 220 can be made closer, which is beneficial to avoid the problem that the accuracy of wireless transmission is affected by the long distance between the first wireless component 150 and the second wireless component 220, thereby improving the accuracy of wireless transmission.

[0084] In one implementation, the electromagnetic shielding component 160 and the first wireless component 150 can be arranged on a side of the upper shell 123 close to the lower shell 124; or, in another implementation, the electromagnetic shielding component 160 and the first wireless component 150 can be arranged on a side of the upper shell 123 away from the lower shell 124.

[0085] In this embodiment, refer to Figure 4 and Figure 5 As shown, the electromagnetic shielding member 160 and the first wireless component 150 are mainly arranged on the side of the upper shell 123 close to the lower shell 124. In this way, it is beneficial to avoid the problem that when the panel 110 is arranged on the side away from the lower shell 124, the panel 110 covers the opening 125 due to the protrusion, thereby ensuring the assembly stability of the panel 110 and the housing 120.

[0086] Specifically, the orthographic projection of the first wireless component 150 on the plane where the lower shell 124 is located is located between the outer side of the electromagnetic heating element 140 and the inner wall surface of the housing 120. In this way, on the one hand, the first wireless component 150 is arranged close to the edge of the housing 120, so that the distance between the first wireless component 150 and the second wireless component 220 on the pot 210 is relatively close, which is beneficial to avoid the problem that the first wireless component 150 and the second wireless component 220 are affected by the long distance in wireless transmission accuracy; on the other hand, it helps to avoid the electromagnetic heating element 140, and further avoid the electromagnetic heating element 140 from interfering with the magnetic field of the first wireless component 150.

[0087] In the embodiment of the present application, the structure of the electromagnetic shielding member 160 is not limited. For example, the electromagnetic shielding member 160 may be annular, wherein the annular means that the electromagnetic shielding member 160 is a hollow structure; or the electromagnetic shielding member 160 may be disc-shaped, wherein the disc-shaped means that the electromagnetic shielding member 160 is a non-hollow structure. The annular or disc-shaped here refers to a closed shape that can form a current loop for the current channel. This is not limited in the present embodiment.

[0088] It should be noted that when the electromagnetic shielding component 160 is a ring-shaped or disk-shaped structure, the principle of electromagnetic shielding is: when the electromagnetic heating component 140 emits a magnetic field, the ring-shaped or disk-shaped electromagnetic shielding component 160 will generate an induced current, and the secondary magnetic field of the induced current is opposite to the original magnetic field of the electromagnetic heating component 140 passing therethrough. The two magnetic fields offset each other to form a magnetic shield, which is beneficial to protect the first wireless component 150 from the magnetic field interference of the electromagnetic heating component 140.

[0089] In the embodiment of the present application, the material of the electromagnetic shielding member 160 can be iron, aluminum, copper or steel. The above metals are good electromagnetic shielding materials, have good electromagnetic wave reflection and absorption capabilities, and have high conductivity, and can isolate electromagnetic interference from the outside to a large extent. This is not limited in the present embodiment.

[0090] Among them, the electromagnetic shielding element 160 can be a good conductor, which refers to a material that is easy to conduct current and usually has a low resistivity. For example, common good conductors include various metals such as silver, copper, gold, mercury or iron, which not only have strong electrical conductivity, but also show good electrical conductivity at room temperature. In this way, it is conducive to generating a stronger secondary magnetic field to counteract the magnetic field of the electromagnetic heating element 140, and at the same time, the resistance thermal effect of the induced current itself is small.

[0091] In the embodiment of the present application, the term "at least part" in which at least part of the electromagnetic shielding component 160 is located on the side of the first wireless component 150 close to the electromagnetic heating component 140 means that the electromagnetic heating component 140 can be entirely located on the side of the first wireless component 150 close to the electromagnetic heating component 140, or the electromagnetic heating component 140 can be partially located on the side of the first wireless component 150 close to the electromagnetic heating component 140. This is not limited in the present embodiment. In this way, when the electromagnetic heating component 140 generates a magnetic field, the secondary magnetic field generated by the electromagnetic heating component 140 offsets the original magnetic field of the electromagnetic heating component 140 to form a magnetic shield, thereby protecting the first wireless component 150 from the magnetic field interference of the electromagnetic heating component 140.

[0092] In the embodiment of the present application, the electromagnetic heating element 140 is spaced apart from the first wireless component 150. This is because if the electromagnetic heating element 140 contacts the first wireless component 150, the electromagnetic heating element 140 will generate electromagnetic interference to the first wireless component 150, affecting the normal signal transmission of the first wireless component 150. Therefore, the electromagnetic heating element 140 is spaced apart from the first wireless component 150, which helps to avoid the problem of electromagnetic interference generated by the electromagnetic heating element 140 to the first wireless component 150, resulting in interruption or instability of wireless communication, and helps to avoid the problem of short circuit failure of the first wireless component 150.

[0093] Therefore, the cooker 100 provided in the embodiment of the present application includes the first wireless component 150 and the electromagnetic shielding component 160, and at least part of the electromagnetic heating component 140 is located on the side of the first wireless component 150 close to the electromagnetic heating component 140. In this way, the electromagnetic shielding component 160 can protect the first wireless component 150 from the magnetic field interference of the electromagnetic heating component 140, and effectively improve the accuracy of the signal transmission of the first wireless component 150.

[0094] In a possible implementation, the electromagnetic shielding member 160 may be a cover structure, and the electromagnetic shielding member 160 is disposed outside the first wireless component 150. The specific shape, size, and installation position of the cover structure are not limited.

[0095] This arrangement, on the one hand, helps to further avoid the magnetic field interference of the electromagnetic heating element 140 on the first wireless component 150, thereby effectively improving the accuracy of signal transmission of the first wireless component 150. On the other hand, the electromagnetic shielding element 160 is arranged outside the first wireless component 150, which can protect the first wireless component 150 and help prevent the first wireless component 150 from being damaged by external forces.

[0096] In order to further ensure the good heat dissipation effect and normal operation of the first wireless component 150 and the electromagnetic shielding member 160. Figure 4 , Figure 6 and Fig.11 As shown, a duct baffle 126 may be provided in the shell 120, and the duct baffle 126 is arranged around at least part of the outer side of the electromagnetic heating element 140, and an air inlet channel 127 is formed between the duct baffle 126 and at least part of the inner wall surface of the shell 120, and the first wireless component 150 and the electromagnetic shielding element 160 are arranged in the air inlet channel 127.

[0097] It can be understood that at least part of the inner wall surface of the shell 120 includes: at least part of the bottom wall surface of the shell 120 and at least part of the side wall surface of the shell 120 .

[0098] In this way, after the air duct baffle 126 is set, it is beneficial to guide and converge the wind flow entering the cavity 122 to a certain extent, so that the wind flow flows along the path of the air inlet channel 127, and the wind flow in the air inlet channel 127 is larger, thereby increasing the amount of wind blowing through the first wireless component 150 and the electromagnetic shielding component 160, which is beneficial to improve the heat dissipation of the first wireless component 150 and the electromagnetic shielding component 160, so that the electromagnetic shielding component 160 and the first wireless component 150 can be quickly cooled down, and further heat dissipation protection for the electromagnetic shielding component 160 and the first wireless component 150 can be achieved, so that the electromagnetic shielding component 160 and the first wireless component 150 can be maintained in a normal temperature range, and the service life of the electromagnetic shielding component 160 and the first wireless component 150 can be extended, which provides a guarantee for the normal operation of the induction cooker, and is beneficial to extending the service life of the induction cooker.

[0099] In a possible implementation, in the embodiment of the present application, referring to Fig.10 and Fig.11 As shown, an air inlet 121 may be opened on the shell 120 , and the air inlet 121 is located on a side close to the air duct baffle 126 , and the first wireless component 150 and the electromagnetic shielding component 160 are located on a side close to the air inlet 121 .

[0100] Specifically, the air inlet 121 and the air outlet 128 are both provided on the lower shell 124, and the air inlet 121 can be composed of a plurality of small holes, which can be circular holes, or elliptical holes, triangular holes, or polygonal holes. The air outlet 128 can be composed of a plurality of small holes, which can be circular holes, or elliptical holes, triangular holes, or polygonal holes. This embodiment does not limit this, and can be specifically set according to actual conditions, as long as normal air intake and exhaust can be ensured.

[0101] It should be noted that the direction of the airflow in this embodiment is: the external wind flow enters the air inlet channel 127 through the air inlet 121, and naturally flows to the first wireless component 150 and the electromagnetic shielding member 160. The first wireless component 150 and the electromagnetic shielding member 160 are arranged close to the air inlet 121, which is conducive to shortening the flow path of the wind flow, thereby quickly achieving heat dissipation protection.

[0102] Alternatively, in this embodiment, a heat dissipation fan 190 is provided in the cavity 122, and the external wind flow enters the cavity 122 through the air inlet 121. Under the action of the heat dissipation fan 190, the first wireless component 150 and the electromagnetic shielding member 160 can be quickly cooled, and the heat dissipated hot wind flow is discharged through the air outlet of the housing 120. For example, the flow direction of the wind flow can refer to Fig.11 Indicated by the direction of the arrow.

[0103] In a specific implementation, the heat dissipation fan 190 may be a centrifugal fan or an axial flow fan, which is not limited in this embodiment.

[0104] In one possible implementation, referring to Figure 7 and Fig. 9 As shown, a ventilation hole 161 may be provided on a side of the electromagnetic shielding member 160 facing away from the first wireless component 150 , and the ventilation hole 161 is close to the air inlet 121 .

[0105] Exemplarily, the vent 161 may be a hollow structure of the electromagnetic shielding member 160. In this way, the airflow enters the inner wall of the first wireless component 150 and the electromagnetic shielding member 160 through the vent 161, which is beneficial to fully utilize the airflow of the air inlet 121 to perform heat dissipation protection on the first wireless component 150 and the electromagnetic shielding member 160, ensure the normal operation of the first wireless component 150 and the electromagnetic shielding member 160, and help extend the service life of the first wireless component 150 and the electromagnetic shielding member 160.

[0106] In one possible implementation, referring to Figure 7 and Fig. 9 As shown, a mounting member 180 may be provided on the housing 120, and the mounting member 180 has a mounting groove 181, and the notch of the mounting groove 181 faces the bottom wall of the housing 120. During assembly, the first wireless component 150 and the electromagnetic shielding member 160 are sequentially assembled in the mounting groove 181, and the electromagnetic shielding member 160 is located on one side of the first wireless component 150 close to the notch of the mounting groove 181.

[0107] Thus, on one hand, by providing the mounting member 180, the first wireless component 150 and the electromagnetic shielding member 160 can be installed, and the assembly stability of the first wireless component 150 and the electromagnetic shielding member 160 can be ensured, thereby helping to ensure the normal operation of the first wireless component 150 and the electromagnetic shielding member 160. On the other hand, providing the mounting member 180 on the housing 120 helps to avoid providing an additional bracket for auxiliary fixing, helps to avoid occupying additional space, and helps to avoid the problem of more obstacles to heat dissipation at this location.

[0108] The assembly relationship between the mounting member 180 and the housing 120 is not limited. For example, the mounting member 180 and the housing 120 may be integrally formed by injection molding, or the mounting member 180 may be a separate part, and the mounting member 180 is connected to the housing 120 by welding or bonding. In this embodiment, the mounting member 180 and the housing 120 are mainly described as an integral part. In this way, it is helpful to reduce the assembly procedures and installation steps, and it is helpful to improve the installation strength of the mounting member 180.

[0109] In one possible implementation, referring to Figures 6 to 9 As shown, the electromagnetic shielding member 160 may include a shielding body 162 and an outer edge portion 163 extending outward from the shielding body 162. The shielding body 162 is an annular structure, and the shielding body 162 is located on one side of the slot of the first wireless component 150 close to the mounting slot 181, and at least part of the outer edge portion 163 is connected to at least part of the mounting member 180.

[0110] There is no limitation on the assembly relationship between the outer edge portion 163 and the shielding body 162. For example, the outer edge portion 163 and the shielding body 162 can be integrally formed by injection molding, or the outer edge portion 163 and the shielding body 162 can be connected by welding or bonding. In this embodiment, the outer edge portion 163 and the shielding body 162 are mainly integrated as an example for description.

[0111] The specific structure of the outer edge portion 163 is not limited. For example, the number of the outer edge portions 163 may include two, and the two outer edge portions 163 are relatively connected to the shielding body 162. In this way, by providing the outer edge portion 163, it is convenient to connect the shielding body 162 and the mounting member 180, and it will not affect the strength of the structure of the shielding body 162 itself. In addition, it is also beneficial to further improve the connection strength and assembly stability of the mounting member 180, the electromagnetic shielding member 160, and the first wireless component 150.

[0112] In one possible implementation, referring to Figures 6 to 9As shown, the mounting member 180 may include a first mounting bracket 182 and a second mounting bracket 183 that are relatively arranged along the extension direction of the length of the mounting groove 181, and a first rib position 184 and a second rib position 185 that are relatively arranged along the extension direction of the width of the mounting groove 181. The first rib position 184, the second rib position 185, the first mounting bracket 182 and the second mounting bracket 183 together enclose the mounting groove 181.

[0113] The first mounting bracket 182 may be provided with a fixed clamping member 186, and the second mounting bracket 183 may be provided with an elastic clamping member 187. During assembly, the first wireless component 150 and the electromagnetic shielding member 160 are assembled in the mounting groove 181, wherein the first ends of the first wireless component 150 and the electromagnetic shielding member 160 are respectively connected to the first mounting bracket 182 through the fixed clamping member 186, and the second ends of the first wireless component 150 and the electromagnetic shielding member 160 are respectively elastically connected to the second mounting bracket 183 through the elastic clamping member 187; the shielding body 162 abuts against the first rib position 184 and the second rib position 185.

[0114] In the embodiment of the present application, the fixed clamping member 186 and the first mounting bracket 182, and the elastic clamping member 187 and the second mounting bracket 183 can be integrally formed by injection molding, or the fixed clamping member 186 and the first mounting bracket 182, and the elastic clamping member 187 and the second mounting bracket 183 can be connected by welding or bonding.

On the other hand, the shielding body 162 abuts against the first rib position 184 and the second rib position 185, wherein the shielding body 162 relies on its own hard material properties to maintain not deforming upward, and at the same time, the shielding body 162 is limited and fixed by the elastic clamping members 187 and the fixed clamping members 186 on both sides, and there is no downward deformation space, which is beneficial to ensure that the first wireless component 150 and the electromagnetic shielding member 160 are suspended in the air without contact.

[0116] In one possible implementation, referring to Figures 6 to 9 As shown, the fixed clamp 186 may include a first fixed clamp portion 1861 and a second fixed clamp portion 1862 spaced apart along the extension direction of the length of the first mounting bracket 182 , and the first fixed clamp portion 1861 is located on one side of the second fixed clamp portion 1862 close to the bottom of the mounting groove 181 .

[0117] During assembly, the first end of the first wireless component 150 is fixedly clamped between the bottom of the installation groove 181 and the first fixed clamping portion 1861 , and a first buckle 1631 may be provided on the outer edge portion 163 , and the first buckle 1631 is fixedly clamped between the first fixed clamping portion 1861 and the second fixed clamping portion 1862 .

[0118] It should be noted that the first fixed clamping portion 1861 and the second fixed clamping portion 1862 are staggered in the upper and lower layers, so that the first wireless component 150 and the electromagnetic shielding component 160 are suspended in the air without contact after installation, which is beneficial to avoid short circuit failure of the first wireless component 150.

[0119] In one possible implementation, referring to Figures 6 to 9 As shown, the elastic clamp 187 may include a first elastic clamp portion 1871 and a second elastic clamp portion 1872 spaced apart along the extension direction of the length of the second mounting bracket 183 , and the first elastic clamp portion 1871 is located on one side of the second elastic clamp portion 1872 close to the bottom of the mounting groove 181 .
