DETAILED DESCRIPTION

[0052] In order to more clearly understand the above objectives, features and advantages of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0053] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0054] The following description refers to the accompanying drawings. Figures 1 to 17A pot 100 and a cooking system 200 are described according to some embodiments of the present application. The pot 100 is applied to the cooking system 200, and the cooking system 200 includes an electromagnetic cooker 300, and the pot 100 is capable of being placed on the electromagnetic cooker 300. The electromagnetic cooker 300 includes a coil disc 330 for heating the pot 100 placed on the electromagnetic cooker 300. The electromagnetic cooker 300 includes an infrared temperature measuring device 340 for measuring the temperature of the pot 100, so as to understand the temperature of the food material contained in the pot 100, and to facilitate the user to control the cooking quality of the food material. Specifically, the infrared temperature measuring device 340 includes a window 341 for receiving infrared rays emitted from the bottom of the detection cavity 140, and the infrared light radiated by the pot 100 is received through the window 341 to realize temperature detection.

[0055] According to the embodiments of the first aspect of the present application, a pot 100 is provided, which includes a magnetic conductive layer 110, a support layer 120 surrounding the outside of the magnetic conductive layer 110, and a detection cavity 140 penetrating through the support layer 120.

[0056] According to the embodiments of the pot 100 provided by the present application, Figure 1 、 Figure 2 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 , the pot 100 includes the magnetic conductive layer 110 and the support layer 120, wherein the support layer 120 surrounds the outside of the magnetic conductive layer 110, the magnetic conductive layer 110 forms a containing cavity for containing food material, and the support layer 120 is used for contacting the electromagnetic cooker 300. Specifically, as shown in Figures 7 to 10 , the electromagnetic cooker 300 includes a panel 320, and the support layer 120 is used for contacting the panel 320. By providing the pot 100 with the detection cavity 140 penetrating through the support layer 120, and by making the window 341 of the infrared temperature measuring device 340 face the detection cavity 140, the infrared light generated during the heating process of the pot 100 is directly received by the infrared temperature measuring device 340 through the detection cavity 140 and the window 341, that is, the infrared light received by the infrared temperature measuring device 340 does not need to pass through the support layer 120, so that the temperature detected by the infrared temperature measuring device 340 is close to or equal to the temperature of the magnetic conductive layer 110. Since the food material is in contact with the magnetic conductive layer 110, the temperature difference between the detected temperature and the temperature of the food material in the magnetic conductive layer 110 is reduced, which is beneficial to improve the accuracy of the temperature measurement of the infrared temperature measuring device 340, and is further beneficial to the user to cook delicious dishes according to the more accurate food material temperature, and to improve the cooking quality of the food material.

[0057] Further, the magnetic conductive layer 110 is a metal material piece, for example, the magnetic conductive layer 110 is a stainless steel metal piece. The magnetic conductive layer 110 is mainly used for heating and containing food materials, and cooking the food materials. That is, under the action of the coil disc 330 of the electromagnetic cooker 300, the magnetic conductive layer 110 inside the support layer 120 can heat and cook the food materials inside the magnetic conductive layer 110, and the support layer 120 does not heat. Compared with the double-layer pot in the related art, the heat is transmitted to the inner pot through the outer pot to cook the food materials in the inner pot, the heat utilization rate is greatly improved, the cooking efficiency is improved, and the application is suitable for popularization and application.

[0058] Further, the support layer 120 is a heat dissipation piece, for example, the support layer 120 is a heat dissipation material piece, that is, the support layer 120 has heat dissipation performance, can quickly dissipate the heat transmitted from the magnetic conductive layer 110 to the outside environment, and then reduce the temperature of the support layer 120, so as to avoid scalding the user during use of the pot 100 due to the high temperature of the support layer 120. It can be understood that in some possible implementation examples provided by the application, the magnetic conductive layer 110 inside the support layer 120 can heat under the action of the coil disc 330, and the support layer 120 is a heat dissipation piece, so that the temperature of the support layer 120 is low during the heating process of the cooking system 200, and the user can touch the support layer 120, thereby improving the user experience.

[0059] Specifically, the support layer 120 is a ceramic piece, a glass piece, an organic high polymer material piece, or other pieces that meet the requirements, and the application does not make specific limitations.

[0060] In some possible implementation examples provided by the application, as shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a heat insulation layer 130 is arranged between the magnetic conductive layer 110 and the support layer 120, and the heat insulation layer 130 includes a hollow structure or a heat insulation material piece 132, that is, the heat insulation layer 130 has the function of heat insulation and heat preservation. The arrangement of the heat insulation layer 130 can prevent the heat of the magnetic conductive layer 110 from being transmitted to the support layer 120, so that the heat generated by the magnetic conductive layer 110 is mainly used for heating the food materials, the heat loss is minimized, the heat utilization rate is improved, the cooking efficiency is improved, and the good cooking effect is ensured.

[0061] The pot 100 comprises a pot body and a pot bottom. The detection cavity 140 is in communication with the magnetic conductive layer 110 at the position of the pot bottom, that is, the detection cavity 140 is arranged at the pot bottom and penetrates through the support layer 120 and the heat insulation layer 130. Since the food materials will mostly fall to the pot bottom under the action of gravity during the cooking process, the temperature difference between the magnetic conductive layer 110 at the position of the pot bottom and the food materials inside the magnetic conductive layer 110 is small. Therefore, the detection cavity 140 is in communication with the magnetic conductive layer 110 at the position of the pot bottom, so that the infrared light is directly received by the infrared temperature measuring device 340 through the window 341 from the magnetic conductive layer 110 at the position of the pot bottom via the detection cavity 140. That is, the temperature detected by the infrared temperature measuring device 340 is the temperature of the magnetic conductive layer 110 which is in contact with the food materials with high possibility, thereby further reducing the temperature difference between the detected temperature and the temperature of the food materials and improving the accuracy of temperature measurement, so that the user can accurately know the temperature of the food materials.

[0062] Further, the detection cavity 140 can be arranged at the central position of the pot bottom or at the portion close to the edge of the pot bottom. For example, when the infrared temperature measuring device 340 of the electromagnetic cooker 300 is arranged inside the coil disc 330 and coaxially arranged with the coil disc 330, the detection cavity 140 can be arranged at the central position of the pot bottom. When the infrared temperature measuring device 340 of the electromagnetic cooker 300 is arranged outside the coil disc 330, the detection cavity 140 can be arranged at the edge position of the pot bottom.

[0063] Further, the portion of the magnetic conductive layer 110 in communication with the detection cavity 140 is provided with an infrared radiation coating. The arrangement of the infrared radiation coating is beneficial to improve the emissivity of the infrared light and further improve the timeliness, accuracy and reliability of the temperature measurement of the infrared temperature measuring device 340. Specifically, the arrangement of the infrared radiation coating can ensure that the emissivity of the infrared light with a wavelength of 6um to 16um reaches more than 95%.

[0064] Further, the area of the portion of the magnetic conductive layer 110 in communication with the detection cavity 140 is greater than the cross-sectional area of the window along the direction parallel to the magnetic conductive layer 110. Such arrangement is beneficial to ensure that the window can effectively receive the infrared light radiated by the magnetic conductive layer 110 and ensure the reliability of the temperature measurement of the infrared temperature measuring device.

[0065] Specifically, the heat insulation layer 130 is a vacuum structure 131, so that the pot 100 is a double-layer pot 100. The heat insulation layer 130 is a heat insulation material piece 132 connected with the magnetic conductive layer 110 and the support layer 120, so that the pot 100 is a three-layer pot 100. Different structures of the heat insulation layer 130 can meet the needs of different costs and different functions of the pot 100, thereby expanding the use range of the product.

[0066] In some possible implementation manners provided in the embodiment, as Figure 1 , Figure 2 , Figure 9 andFigure 10 As shown, the heat insulation layer 130 comprises a vacuum structure 131 and a sealing member 160, the sealing member 160 is arranged at the communication between the detection cavity 140 and the vacuum structure 131, and is connected with the magnetic conductive layer 110 and the support layer 120, through the arrangement of the sealing member 160, the sealing property of the vacuum structure 131 can be ensured, and further, the vacuum structure 131 has good heat insulation and heat preservation effect.

[0067] Specifically, the sealing member 160 is high-temperature glue, the high-temperature glue directly seals the communication between the detection cavity 140 and the vacuum structure 131, the operation is simple, and the sealing reliability is high. It can be understood that the sealing member 160 can also be other structures meeting the requirements, and the present application is not limited specifically.

[0068] Further, the pot 100 further comprises an elastic member, a through hole 321 communicated with the vacuum structure 131 is arranged at the support layer 120 corresponding to the pot body, that is, the through hole 321 penetrates the side wall of the support layer 120, the elastic member is arranged at the through hole 321 and is connected with the support layer 120 to seal the through hole 321, since the elastic member is arranged to be driven by gas to deform, when the vacuum structure 131 leaks, the elastic member at the pot body deforms under the action of the gas, so as to remind the user that the vacuum structure 131 has a leakage fault, and the pot 100 can be maintained in time.

[0069] Specifically, the elastic member is a silica gel elastic piece, when the pot 100 is in a normal state, that is, the vacuum structure 131 does not leak, the silica gel elastic piece is concave inward or flush with the outer surface of the support layer 120 at the pot body, when the vacuum structure 131 leaks, the elastic member elastically deforms, changes from concave inward to flush with the outer surface of the support layer 120 at the pot body or protrudes outward, or changes from flush with the outer surface of the support layer 120 at the pot body to protrude outward, so as to remind the user that the vacuum structure 131 has a leakage fault.

[0070] In some possible implementation of the present application, since the food material falls downward under the action of gravity during the cooking process, the temperature measuring layer is arranged at the bottom of the at least partial magnetic conductive layer 110, that is, the temperature measuring layer is arranged at the bottom of the magnetic conductive layer 110 at the position of the pot bottom, the detection cavity 140 is in communication with the temperature measuring layer, that is, the detection cavity 140 is arranged at the pot bottom, which is beneficial to reduce the temperature difference between the detection temperature of the infrared temperature measuring device 340 and the temperature of the food material inside the magnetic conductive layer 110. Since the detection cavity 140 is in communication with the temperature measuring layer, the infrared light is directly received by the infrared temperature measuring device 340 through the detection cavity 140 and the window 341 via the temperature measuring layer, that is, the temperature detected by the infrared temperature measuring device 340 is the temperature of the temperature measuring layer. By reasonably arranging the temperature measuring layer, the temperature conducted to the temperature measuring layer via the magnetic conductive layer 110 is equivalent to the temperature conducted to the food material via the magnetic conductive layer 110. Therefore, the temperature of the food material can be determined by detecting the temperature of the temperature measuring layer via the infrared temperature measuring device 340, which greatly improves the accuracy of temperature measurement and facilitates the user to ensure the good quality of the food material according to the accurate temperature of the food material.

[0071] In some possible implementation of the present application, as shown in Figure 2 、 Figure 6 、 Figure 9 、 Figure 10 、 Figure 12 and Figure 13 , the pot 100 further comprises a magnetic shielding ring 150, the magnetic shielding ring 150 is arranged around the inner wall of the detection cavity 140, and the magnetic shielding ring 150 is connected to or abuts against the magnetic conductive layer 110 or the temperature measuring layer in communication with the detection cavity 140. That is, in the case that the detection cavity 140 is in communication with the magnetic conductive layer 110, the magnetic shielding ring 150 is connected to or abuts against the magnetic conductive layer 110, and in the case that the detection cavity 140 is in communication with the temperature measuring layer, the magnetic shielding ring 150 is connected to or abuts against the temperature measuring layer. It can be understood that the connection or abutment here means installation or contact, that is, the magnetic shielding ring 150 is in contact with or installed on the magnetic conductive layer 110, or the magnetic shielding ring 150 is in contact with or installed on the temperature measuring layer.

[0072] Since the electromagnetic radiation generated by the coil disc 330 of the electromagnetic cooker 300 radiates to the detection cavity 140, it can interfere with the accuracy of temperature measurement of the infrared temperature measuring device 340. For example, if the infrared temperature measuring device 340 comprises a metal part, and the electromagnetic radiation radiates to the metal part via the detection cavity 140 to heat the metal part, which can affect the accuracy of temperature measurement of the infrared temperature measuring device 340. Therefore, by arranging the magnetic shielding ring 150, the electromagnetic radiation generated by the coil disc 330 can be blocked from radiating to the inside of the detection cavity 140, which can eliminate the interference of the electromagnetic radiation on the accuracy of temperature measurement of the infrared temperature measuring device 340, and is beneficial to improve the accuracy of detection of the infrared temperature measuring device 340.

[0073] It can be understood that the infrared temperature measuring device 340 is arranged inside the coil disc 330, and the magnetic shielding ring 150 can shield the electromagnetic. The magnetic shielding ring 150 is a metal poor magnetic conductive material piece, for example, the magnetic shielding ring 150 is an aluminum piece, a copper piece, a silver piece, or other poor magnetic conductive material pieces that meet the requirements.

[0074] Further, the magnetic shielding ring 150 is bonded to the inner wall of the detection cavity 140, for example, the magnetic shielding ring 150 is bonded to the inner wall of the detection cavity 140 by a high-temperature adhesive. It can be understood that the magnetic shielding ring 150 can also be fixed to the inner wall of the detection cavity 140 by other means that meet the requirements. Specifically, if the pot 100 includes the magnetic conductive layer 110 and the support layer 120, that is, the detection cavity 140 only penetrates the support layer 120, the magnetic shielding ring 150 is bonded to the inner wall of the detection cavity 140 arranged on the support layer 120; if the pot 100 includes the magnetic conductive layer 110, the heat insulation layer 130, and the support layer 120, that is, the detection cavity 140 penetrates the heat insulation layer 130 and the support layer 120, the magnetic shielding ring 150 is bonded to the inner wall of the detection cavity 140 formed by the support layer 120 and the heat insulation material piece 132, or the magnetic shielding ring 150 is bonded to the inner wall of the detection cavity 140 formed by the support layer 120 and the sealing piece 160.

[0075] Specifically, the magnetic shielding ring 150 is connected or abuts with the magnetic conductive layer 110, and the magnetic shielding ring 150 is connected or abuts with the temperature measuring layer, which can ensure that the electromagnetic generated by the coil disc 330 will not be radiated to the magnetic conductive layer 110 through the detection cavity 140, and can meet the requirements of different connection modes of the magnetic shielding ring 150 and the pot 100, thereby expanding the use range of the product.

[0076] In this embodiment, by reasonably arranging the structure of the magnetic shielding ring 150 and the detection cavity 140, the interference of the electromagnetic on the temperature measuring accuracy of the infrared temperature measuring device 340 can be effectively eliminated when the magnetic shielding ring 150 is in different positions, and the detection accuracy of the infrared temperature measuring device 340 is improved.

[0077] Specifically, as shown in Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 , the infrared temperature measuring device 340 is coaxially arranged with the coil disc 330, the magnetic shielding ring 150 is coaxially arranged with the coil disc 330, and the outer diameter of the magnetic shielding ring 150 is smaller than the inner diameter of the coil disc 330, that is, the magnetic shielding ring 150 is located inside the coil disc 330. Further, in order to ensure that the electromagnetic shielded by the magnetic shielding ring 150 will not be radiated to the detection cavity 140, a magnetic conductive ring 350 is arranged outside the infrared temperature measuring device 340, and the magnetic conductive ring 350 is used to guide the radiation direction of the electromagnetic so that the electromagnetic will not be radiated to the inside of the detection cavity 140.

[0078] In one aspect, as shown in FIG. 1, when the magnetic shielding ring 150 and the magnetic conducting ring 350 are arranged in a vertical direction, the outer diameter of the magnetic shielding ring 150 is smaller than the outer diameter of the magnetic conducting ring 350 and larger than the inner diameter of the magnetic conducting ring 350, or the inner diameter of the magnetic shielding ring 150 is larger than the inner diameter of the magnetic conducting ring 350 and smaller than the outer diameter of the magnetic conducting ring 350, the lowest point height of the magnetic shielding ring 150 is higher than the lowest point height of the detection cavity 140, that is, the magnetic shielding ring 150 is arranged in the detection cavity 140, and the height difference between the lowest point of the magnetic shielding ring 150 and the lowest point of the detection cavity 140 is less than 5 mm, for example, as shown in FIG. 1, the height difference is less than 5 mm, specifically, the height difference is 2 mm, 2.5 mm or 3 mm, which can ensure that the electromagnetic wave shielded by the magnetic shielding ring 150 is guided by the magnetic conducting ring 350 and will not be radiated to the inside of the detection cavity 140, effectively eliminating the interference of the electromagnetic wave on the detection accuracy of the infrared temperature measuring device 340, and greatly improving the temperature measurement accuracy of the infrared temperature measuring device 340. Figure 2

[0079] Further, in this way, when the pot 100 is placed on the electromagnetic cooker 300, the magnetic shielding ring 150 does not contact the panel 320 of the electromagnetic cooker 300, which can avoid the heat transferred by the magnetic shielding ring 150 from affecting the temperature measurement accuracy of the infrared temperature measuring device 340. It can be understood that, when the heat transferred by the magnetic shielding ring 150 is small or no heat is transferred, the lowest point height of the magnetic shielding ring 150 can be lower than or equal to the lowest point height of the detection cavity 140.

[0080] On the other hand, as shown in FIG. 1, when the infrared temperature measuring device 340 and the coil disc 330 are coaxially arranged, the magnetic shielding ring 150 and the coil disc 330 are concentrically arranged, the outer diameter of the magnetic shielding ring 150 is smaller than the inner diameter of the magnetic conducting ring 350, that is, the magnetic shielding ring 150 is located in the inside of the magnetic conducting ring 350, and the magnetic shielding ring 150 and the coil disc 330 are horizontally staggered, the lowest point height of the magnetic shielding ring 150 is lower than or equal to the lowest point height of the detection cavity 140, which can ensure that the electromagnetic wave shielded by the magnetic shielding ring 150 is guided by the magnetic conducting ring 350 and will not be radiated to the inside of the detection cavity 140, effectively eliminating the interference of the electromagnetic wave on the detection accuracy of the infrared temperature measuring device 340, and greatly improving the temperature measurement accuracy of the infrared temperature measuring device 340.

[0081] In the above embodiment, on the one hand, as shown in FIG. 1, along the height direction of the detection cavity 140, the width of the detection cavity 140 is equal, that is, the inner wall of the detection cavity 140 is a smooth curved surface structure or a smooth plane structure, for example, the detection cavity 140 is a cylindrical cavity with equal diameters, at this time, the magnetic shielding ring 150 is arranged around the inner wall of the detection cavity 140, and it can be understood that the lowest point height of the magnetic shielding ring 150 can be higher than, equal to or lower than the lowest point height of the detection cavity 140. Figure 10 Figure 12 In the above embodiment, on the one hand, as shown in FIG. 1, along the height direction of the detection cavity 140, the width of the detection cavity 140 is equal, that is, the inner wall of the detection cavity 140 is a smooth curved surface structure or a smooth plane structure, for example, the detection cavity 140 is a cylindrical cavity with equal diameters, at this time, the magnetic shielding ring 150 is arranged around the inner wall of the detection cavity 140, and it can be understood that the lowest point height of the magnetic shielding ring 150 can be higher than, equal to or lower than the lowest point height of the detection cavity 140.​​

[0082] In another aspect, as shown in Figure 5 and Figure 6 , the inner wall of the detection cavity 140 is provided with a groove structure 141 accommodating the magnetic shielding ring 150 along the circumferential side, that is, the groove structure 141 is arranged on the side of the detection cavity 140 close to the magnetic conductive layer 110, and the magnetic shielding ring 150 is accommodated in the groove structure 141. That is, the inner wall of the detection cavity 140 is a bent curved surface structure or a bent plane structure. In this case, the lowest point of the magnetic shielding ring 150 is higher than the lowest point of the detection cavity 140. Therefore, the height of the shielding ring is equal to the height of the groove structure 141, and the thickness of the shielding ring is equal to the groove depth of the groove structure 141, so that the inner wall of the magnetic shielding ring 150 accommodated in the groove structure 141 is flush with the inner wall of the detection cavity 140. Such arrangement is conducive to increasing the propagation space of infrared rays transmitted from the pot 100 to the infrared temperature measuring device 340, and further conducive to improving the reliability of temperature measurement of the infrared temperature measuring device 340. Specifically, the height difference between the lowest point of the groove structure 141 and the lowest point of the detection cavity 140 is less than or equal to 5 mm.

[0083] In a second aspect of the present application, as shown in Figures 7 to 17 , a cooking system 200 is provided, comprising: an electromagnetic stove 300; and the pot 100 of any one of the first aspect, the pot 100 being adapted to be placed on the electromagnetic stove 300. Since the cooking system 200 comprises the pot 100 of any one of the embodiments of the first aspect, the pot 100 has all the beneficial technical effects, which will not be repeated here.

[0084] Further, as shown in Figure 7 , Figure 8 , Figure 9 and Figure 10 , the electromagnetic stove 300 comprises a housing 310, a panel 320 and a coil disc 330, wherein the housing 310 is provided with an opening, the panel 320 is connected to the housing 310 at the opening, the panel 320 is used to carry the pot 100, that is, the pot 100 is adapted to be placed on the panel 320, and the coil disc 330 is arranged inside the housing 310 and below the panel 320, that is, the coil disc 330 works to produce electromagnetic effect on the pot 100 to heat the pot 100 for cooking food. The panel 320 is made of a medium-temperature-resistant plastic part, so that the panel 320 of the electromagnetic stove 300 is convenient to process and has low cost, which is suitable for popularization and application.

[0085] Further, the electromagnetic cooker 300 provided by the present application, when the pot 100 is placed on the electromagnetic cooker 300, the support layer 120 of the pot 100 is in contact with the panel 320, the electromagnetic generated by the coil disc 330 acts on the magnetic conductive layer 110 inside the support layer 120, so that the magnetic conductive layer 110 generates heat and cooks the food inside the magnetic conductive layer 110. Since the support layer 120 of the pot 100 will not heat up due to the electromagnetic effect, the temperature of the support layer 120 in contact with the panel 320 is relatively low, so that the panel 320 made of medium and low temperature resistant plastic parts provided by the present application can meet the temperature requirements of the support layer 120, that is, the electromagnetic cooker 300 provided by the present application can ensure that the panel 320 in contact with the support layer 120 of the pot 100 has high reliability during the heating process of the pot 100, at the same time, the panel 320 made of medium and low temperature resistant plastic parts reduces the manufacturing cost and processing difficulty of the panel 320, thereby reducing the cost of the electromagnetic cooker 300, and is suitable for popularization and application.

[0086] Specifically, the panel 320 includes a polyphenyl ether part, such as a PPO plastic part; or the panel 320 includes a polycarbonate part, such as a PC part, specifically, a high molecular polymer part containing a carbonate group in the molecular chain; or the panel 320 is a mixed part of polyphenyl ether and polycarbonate, such as a mixed part of PPO and PC; or the panel 320 is spliced from a polyphenyl ether part and a polycarbonate part.

[0087] Among them, the temperature resistance range of the panel 320 is 80-200℃, and specifically, the temperature resistance of the panel 320 is resistant to 80℃, 100℃, 150℃, 200℃ or other values meeting the requirements, that is, the panel 320 is a medium and low temperature resistant plastic part. Since the electromagnetic cooker 300 provided by the present application cooks food by heating the magnetic conductive layer 110 inside through electromagnetic effect, the support layer 120 in contact with the panel 320 will not heat up due to the electromagnetic effect (the surface temperature is about 80℃ measured by experiment), so the temperature of the support layer 120 is relatively low, and the panel 320 made of medium and low temperature resistant plastic parts with a temperature resistance range of 80-200℃ can meet the requirements of the non-magnetic conductive layer 110 for the temperature resistance of the panel 320.

[0088] Further, a heat insulation layer 130 can be arranged between the magnetic conductive layer 110 and the support layer 120 of the pot 100. The heat insulation layer 130 has the function of heat insulation and heat preservation, and the arrangement of the heat insulation layer 130 can prevent the heat of the magnetic conductive layer 110 from being transferred to the support layer 120, so that the heat generated by the magnetic conductive layer 110 is mainly used for heating food, and the heat loss is minimized, thereby further reducing the temperature of the support layer 120 and the requirement for temperature resistance of the panel 320, so that the panel 320 made of medium and low temperature resistant plastic parts can ensure the reliability of the cooking system 200.

[0089] In some possible implementation of the present application, as shown in Figure 8 , Figure 10 , Figure 11 , Figure 12 and Figure 13 , the electromagnetic cooker 300 further comprises an infrared temperature measuring device 340, which is arranged inside the coil disc 330 and comprises a window 341. It can be understood that the infrared light radiated by the cookware 100 is received by the infrared temperature measuring device 340 through the window 341 to realize temperature measurement. By arranging a through hole 321 on the panel 320, the window 341 is located inside the through hole 321, or is arranged opposite to the through hole 321, or is arranged through the through hole 321. When the cookware 100 is placed on the panel 320, the window 341 of the infrared temperature measuring device 340 faces the detection cavity 140, so that the infrared light radiated by the cookware 100 is directly received by the infrared temperature measuring device 340 through the window 341 from the detection cavity 140 through the magnetic conductive layer 110 at the position of the bottom of the cookware 100. The infrared light received by the infrared temperature measuring device 340 does not pass through the support layer 120 and the panel 320, that is, the temperature detected by the infrared temperature measuring device 340 is the temperature of the magnetic conductive layer 110 which is likely to contact the food material. Therefore, it is beneficial to further reduce the temperature difference between the detected temperature and the temperature of the food material, improve the accuracy of temperature measurement, so that the user can accurately know the temperature of the food material, and improve the cooking quality of the food material.

[0090] Further, the window 341 is located inside the through hole 321, or the window 341 is arranged opposite to the through hole 321, or the window 341 is arranged through the through hole 321. The different positional relationship between the window 341 and the through hole 321 can meet the demand of different structures of the electromagnetic cooker 300, and expand the use range of the product. Specifically, the window 341 of the infrared temperature measuring device 340 is coaxially arranged with the coil disc 330.

[0091] In some possible implementation of the present application, as shown in Figures 8 to 17 , since the infrared temperature measuring device 340 comprises a metal part, and the electromagnetic generated by the coil disc 330 acts on the metal part to heat the metal part, which affects the accuracy of temperature measurement of the infrared temperature measuring device 340. The electromagnetic cooker 300 further comprises a magnetic conductive ring 350, which is arranged around the side of the infrared temperature measuring device 340. The magnetic conductive ring 350 is used to guide the radiation direction of the electromagnetic, so that the electromagnetic is not radiated to the metal part of the infrared temperature measuring device 340, that is, the influence of the electromagnetic on the accuracy of temperature measurement of the infrared temperature measuring device 340 is eliminated, and the accuracy of temperature measurement of the infrared temperature measuring device 340 is improved. Specifically, the magnetic conductive ring 350 is a nickel-zinc magnetic ring. It can be understood that the magnetic conductive ring 350 can also be other magnetic rings meeting the requirements, which are not limited in the present application.

[0092] Further, when the pot 100 is placed on the panel 320, the gap width between the magnetic conducting ring 350 and the magnetic shielding ring 150 of the pot 100 is less than or equal to 4 mm. Such arrangement can avoid the electromagnetic generated by the coil disc 330 from entering the detection cavity 140 and the through hole 321 through the gap between the magnetic conducting ring 350 and the magnetic shielding ring 150, that is, the electromagnetic radiated to the magnetic shielding ring 150 will be radiated along the guiding direction of the magnetic conducting ring 350 after being shielded by the magnetic shielding ring 150, and the electromagnetic radiated to the magnetic conducting ring 350 will also be radiated along the guiding direction of the magnetic conducting ring 350, so that the electromagnetic is hardly radiated to the inside of the detection cavity 140 and the through hole 321, thereby eliminating the interference of the electromagnetic on the temperature measurement accuracy of the infrared temperature measuring device 340 and improving the temperature measurement accuracy of the infrared temperature measuring device 340.

[0093] In the above embodiments, according to the different arrangement positions of the magnetic conducting ring 350 and the magnetic shielding ring 150, the gap width between the magnetic conducting ring 350 and the magnetic shielding ring 150 of the pot 100 includes the vertical direction, the horizontal direction or the oblique direction gap of the opposite faces of the magnetic conducting ring 350 and the magnetic shielding ring 150 close to each other, or other distances meeting the requirements, which should be less than or equal to 4 mm.

[0094] In the above embodiments, the magnetic shielding ring 150 and the magnetic conducting ring 350 are preferably regular circular rings arranged in axial symmetry and coaxially, of course, they can also be made into polygons or other irregular structures, or can be arranged in different axes, but the magnetic shielding ring 150 and the magnetic conducting ring 350 should be matched with each other and meet the requirement that the gap therebetween is less than or equal to 4 mm.

[0095] Specifically, when the pot 100 is placed on the panel 320, the gap width between the magnetic conducting ring 350 and the magnetic shielding ring 150 is 0 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, or other values meeting the requirements, which are not limited in the present application.

[0096] In the above embodiments, the gap width between the magnetic conducting ring 350 and the magnetic shielding ring 150 of the pot 100 is less than or equal to 4 mm, which includes the following cases:

[0097] The first case is as follows: Figure 15 and Figure 16As shown, when the radial projections of the magnetic shielding ring 150 and the magnetic conductive ring 350 overlap, the gap width between the magnetic shielding ring 150 and the magnetic conductive ring 350 refers to the radial distance between the opposing surfaces of the magnetic shielding ring 150 and the magnetic conductive ring 350. Therefore, by ensuring that the radial distance between the opposing surfaces of the magnetic shielding ring 150 and the magnetic conductive ring 350 is less than or equal to 4 mm, electromagnetic radiation will not (or very little) be radiated through the gap into the detection cavity 140 and the through hole 321, thereby not interfering with the temperature measurement accuracy of the infrared temperature measuring device 340. In other words, electromagnetic interference with the temperature measurement accuracy of the infrared temperature measuring device 340 can be effectively eliminated. The radial projection refers to the projection of the magnetic shielding ring 150 and the magnetic conductive ring 350 in a plane passing through the axis, such as the projection of the magnetic shielding ring 150 and the magnetic conductive ring 350 in a vertical plane passing through the axis.

[0098] The second type of situation, such as Figure 14 and Figure 19 As shown, when the axial projections of the magnetic shielding ring 150 and the magnetic conductive ring 350 overlap, the gap width between the magnetic shielding ring 150 and the magnetic conductive ring 350 refers to the distance between the bottom surface of the magnetic shielding ring 150 and the top surface of the magnetic conductive ring 350. Therefore, by ensuring that the distance between the bottom surface of the magnetic shielding ring 150 and the top surface of the magnetic conductive ring 350 is less than or equal to 4 mm, electromagnetic radiation will not (or very little) radiate through the gap into the detection cavity 140 and the through hole 321, thereby not interfering with the temperature measurement accuracy of the infrared temperature measuring device 340. In other words, electromagnetic interference with the temperature measurement accuracy of the infrared temperature measuring device 340 can be effectively eliminated. The axial projection refers to the projection of the magnetic shielding ring 150 and the magnetic conductive ring 350 in a plane perpendicular to the axis, such as the projection of the magnetic shielding ring 150 and the magnetic conductive ring 350 in a horizontal plane perpendicular to the axis.

[0099] The third category, such as Figure 17 and Figure 18 As shown, when the axial projections of the magnetic shielding ring 150 and the magnetic conductive ring 350 do not overlap and the radial projections do not overlap, at this time, on the longitudinal section passing through the axis of the magnetic shielding ring 150 and the magnetic conductive ring 350, the distance between the two opposite vertices of the magnetic shielding ring 150 and the magnetic conductive ring is the gap width between the magnetic shielding ring 150 and the magnetic conductive ring 350. Therefore, on the longitudinal section passing through the axis of the magnetic shielding ring 150 and the magnetic conductive ring 350, the distance between the two opposite vertices of the magnetic shielding ring 150 and the magnetic conductive ring is less than or equal to 4 mm, so that the electromagnetic radiation will not (or very little) be radiated through the gap into the detection cavity 140 and the through hole 321, and thus will not interfere with the temperature measurement accuracy of the infrared temperature measuring device 340, that is, it can effectively eliminate the interference of the electromagnetic radiation on the temperature measurement accuracy of the infrared temperature measuring device 340.

[0100] Specifically, on the one hand, the lowest point height of the magnetic shielding ring 150 of the cookware 100 is higher than or equal to the highest point height of the magnetic conductive ring 350, that is, the magnetic shielding ring 150 and the magnetic conductive ring 350 are not arranged opposite each other in the horizontal direction, that is, the magnetic shielding ring 150 and the magnetic conductive ring 350 are arranged in sequence or at intervals in the horizontal direction, that is, the two are staggered in the horizontal direction, that is, the radial projections of the magnetic shielding ring 150 and the magnetic conductive ring 350 do not overlap, which is suitable for the second and third cases mentioned above. The outer ring diameter of the magnetic shielding ring 150 is smaller than the inner ring diameter of the coil disk 330, that is, the magnetic shielding ring 150 is located inside the coil disk 330. In this embodiment, the outer ring diameter refers to the distance from the outer side of the ring to the center of the ring, and the inner ring diameter refers to the distance from the inner side of the ring to the center of the ring.

[0101] In the first case, if Figure 17 As shown, when the inner ring diameter of the magnetic shielding ring 150 is greater than or equal to the outer ring diameter of the magnetic conductive ring 350, that is, the magnetic shielding ring 150 is located on the side of the magnetic conductive ring 350 away from the infrared temperature measuring device 340, at this time, the magnetic shielding ring 150 and the magnetic conductive ring 350 are not arranged opposite to each other in the vertical direction, that is, the magnetic shielding ring 150 and the magnetic conductive ring 350 are arranged in sequence or at intervals in the vertical direction, that is, the two are staggered in the vertical direction. In other words, in this case, the magnetic shielding ring 150 and the magnetic conductive ring 350 are staggered in both the horizontal and vertical directions, that is, the axial projections of the magnetic shielding ring 150 and the magnetic conductive ring 350 do not overlap and the radial projections do not overlap, which is suitable for the third case mentioned above. Since the magnetic shielding ring 150 is located on the outside of the magnetic conductive ring 350, the distance between the lowest point of the inner ring surface of the magnetic shielding ring 150 and the highest point of the outer ring surface of the magnetic conductive ring 350 is the width of the gap between the magnetic shielding ring 150 and the magnetic conductive ring 350, as shown in FIG. Figure 17 As shown by H in the figure, at this time, the lowest point of the inner ring surface of the magnetic shielding ring 150 and the highest point of the outer ring surface of the magnetic conductive ring 350 are the closest points between the two. Therefore, by limiting the distance between the lowest point of the inner ring surface of the magnetic shielding ring 150 and the highest point of the outer ring surface corresponding to the magnetic conductive ring 350 to be less than or equal to 4mm, specifically, such as 0mm, 1mm, 2mm, 3mm, 4mm, or other values ​​that meet the requirements, the electromagnetic radiation will not (or very little) be radiated through the gap into the detection cavity 140 and the through hole 321, and will not interfere with the accuracy of temperature measurement by the infrared temperature measuring device 340, that is, the interference of the electromagnetic radiation on the temperature measurement accuracy of the infrared temperature measuring device 340 can be effectively eliminated.

[0102] In the second case, if Figure 18As shown, when the outer ring diameter of the magnetic shielding ring 150 is less than or equal to the inner ring diameter of the magnetic conducting ring 350, that is, the magnetic shielding ring 150 is located on the side of the magnetic conducting ring 350 close to the infrared temperature measuring device 340, that is, the magnetic shielding ring 150 is located on the inner side of the magnetic conducting ring 350, at this time, the magnetic shielding ring 150 and the magnetic conducting ring 350 are not arranged opposite to each other along the vertical direction, that is, the magnetic shielding ring 150 and the magnetic conducting ring 350 are arranged or spaced along the vertical direction in turn, that is, the two are arranged staggered along the vertical direction. That is, in this case, the magnetic shielding ring 150 and the magnetic conducting ring 350 are staggered along the horizontal direction and the vertical direction, that is, the projection of the magnetic shielding ring 150 and the magnetic conducting ring 350 in the axial direction does not overlap and the projection in the radial direction also does not overlap, which is suitable for the third case mentioned above. Since the magnetic shielding ring 150 is located on the inner side of the magnetic conducting ring 350, the distance between the lowest point of the outer ring surface of the magnetic shielding ring 150 and the highest point of the inner ring surface of the magnetic conducting ring 350 corresponding thereto is the width of the gap between the magnetic shielding ring 150 and the magnetic conducting ring 350, as shown by H in Figure 18 , that is, at this time, the lowest point of the outer ring surface of the magnetic shielding ring 150 and the highest point of the inner ring surface of the magnetic conducting ring 350 are the closest position points of the two, therefore, by limiting the distance between the lowest point of the outer ring surface of the magnetic shielding ring 150 and the highest point of the inner ring surface of the magnetic conducting ring 350 corresponding thereto to be less than or equal to 4mm, specifically, such as 0mm, 1mm, 2mm, 3mm, 4mm, or other values required to meet the requirements, so that electromagnetic radiation will not be radiated to the detection cavity 140 and the through hole 321 through the gap, and further will not interfere with the accuracy of the temperature measurement of the infrared temperature measuring device 340, that is, it can effectively eliminate the interference of electromagnetic on the temperature measurement accuracy of the infrared temperature measuring device 340.

[0103] As shown in Figure 14 , when the inner ring diameter of the magnetic shielding ring 150 is greater than or equal to the inner ring diameter of the magnetic conducting ring 350 and less than the outer ring diameter of the magnetic conducting ring 350, at this time, at least the inner ring surface of the magnetic shielding ring 150 and the magnetic conducting ring 350 are arranged opposite to each other along the vertical direction, that is, along the vertical direction, at least the inner ring surface of the magnetic shielding ring 150 and the magnetic conducting ring 350 are arranged opposite to each other, that is, in this case, the magnetic shielding ring 150 and the magnetic conducting ring 350 are staggered along the horizontal direction, and at least partially arranged opposite to each other along the vertical direction, that is, the projection of the magnetic shielding ring 150 and the magnetic conducting ring 350 in the axial direction overlaps, and the projection in the radial direction does not overlap, which is suitable for the second case mentioned above. The distance between the opposite surfaces of the magnetic shielding ring 150 and the magnetic conducting ring 350 is the width of the gap between the magnetic shielding ring 150 and the magnetic conducting ring 350, and at this time, the bottom surface of the magnetic shielding ring 150 is opposite to the top surface of the magnetic conducting ring 350, as shown by H in Figure 14H, that is, the lowest point of the magnetic shielding ring 150 and the highest point of the magnetic conducting ring 350 are the closest position points of the two, thus, by limiting the distance between the opposite surfaces of the magnetic shielding ring 150 and the magnetic conducting ring 350 to be less than or equal to 4 mm, specifically, such as 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, or other values meeting the requirements, the electromagnetic waves will not be radiated to the detection cavity 140 and the through hole 321 through the gap, and thus will not interfere with the accuracy of the temperature measurement of the infrared temperature measurement device 340, that is, the electromagnetic interference on the temperature measurement accuracy of the infrared temperature measurement device 340 can be effectively eliminated.

[0104] In the fourth case, as shown in Figure 19 the outer ring diameter of the magnetic shielding ring 150 is greater than or equal to the inner ring diameter of the magnetic conducting ring 350, and less than the outer ring diameter of the magnetic conducting ring 350, at this time, at least the outer ring surface of the magnetic shielding ring 150 and the magnetic conducting ring 350 are arranged opposite to each other in the vertical direction, that is, in the vertical direction, at least the outer ring surface of the magnetic shielding ring 150 and the magnetic conducting ring 350 are arranged opposite to each other, that is, in this case, the magnetic shielding ring 150 and the magnetic conducting ring 350 are arranged opposite to each other in the horizontal direction, and at least partially arranged opposite to each other in the vertical direction, that is, the projections of the magnetic shielding ring 150 and the magnetic conducting ring 350 in the radial direction do not overlap, and the projections in the axial direction overlap, which is suitable for the second case mentioned above. The shortest distance between the opposite surfaces of the magnetic shielding ring 150 and the magnetic conducting ring 350 is the width of the gap between the magnetic shielding ring 150 and the magnetic conducting ring 350, and at this time, the bottom surface of the magnetic shielding ring 150 and the top surface of the magnetic conducting ring 350 are opposite, as shown in Figure 19 H, that is, the lowest point of the magnetic shielding ring 150 and the highest point of the magnetic conducting ring 350 are the closest position points of the two, thus, by limiting the distance between the opposite surfaces of the magnetic shielding ring 150 and the magnetic conducting ring 350 to be less than or equal to 4 mm, specifically, such as 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, or other values meeting the requirements, the electromagnetic waves will not be radiated to the detection cavity 140 and the through hole 321 through the gap, and thus will not interfere with the accuracy of the temperature measurement of the infrared temperature measurement device 340, that is, the electromagnetic interference on the temperature measurement accuracy of the infrared temperature measurement device 340 can be effectively eliminated.

[0105] On the other hand, based on the lowest point of the magnetic shielding ring 150 being lower than the highest point of the magnetic conducting ring 350, that is, the magnetic shielding ring 150 and the magnetic conducting ring 350 cannot be arranged opposite to each other in the horizontal direction, that is, in the horizontal direction, the lowest point of the magnetic shielding ring 150 and the highest point of the magnetic conducting ring 350 are arranged opposite to each other, that is, the projections of the magnetic shielding ring 150 and the magnetic conducting ring 350 in the axial direction do not overlap, and the projections in the radial direction overlap, which is suitable for the first case mentioned above.

[0106] In the first case, as shown in Figure 15As shown, when the inner ring diameter of the magnetic shielding ring 150 is greater than or equal to the outer ring diameter of the magnetic conductive ring 350, that is, the magnetic shielding ring 150 is located on the side of the magnetic conductive ring 350 away from the infrared temperature measuring device 340, and the outer ring diameter of the magnetic shielding ring 150 is smaller than the inner ring diameter of the coil disk 330, that is, the magnetic shielding ring 150 is located inside the coil disk 330, that is, the magnetic shielding ring 150 is located between the coil disk 330 and the magnetic conductive ring 350, and the magnetic shielding ring 150 and the magnetic conductive ring 350 are not arranged relative to each other in the vertical direction, that is, the two are staggered in the vertical direction. In this case, the shortest distance between the inner ring surface of the magnetic shielding ring 150 and the corresponding outer ring surface of the magnetic conductive ring 350 is the width of the gap between the magnetic shielding ring 150 and the magnetic conductive ring 350, as shown in FIG. Figure 15 As shown in H in the figure, therefore, by limiting the distance between the inner ring surface of the magnetic shielding ring 150 and the corresponding outer ring surface of the magnetic conductive ring 350 to be less than or equal to 4 mm, specifically, such as 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, or other values ​​that meet the requirements, the electromagnetic radiation will not be radiated into the detection cavity 140 and the through hole 321 through the gap, and will not interfere with the accuracy of temperature measurement by the infrared temperature measuring device 340, that is, the interference of the electromagnetic radiation on the temperature measurement accuracy of the infrared temperature measuring device 340 can be effectively eliminated.

[0107] In the second case, if Figure 16 As shown, when the outer ring diameter of the magnetic shielding ring 150 is less than or equal to the inner ring diameter of the magnetic conductive ring 350, that is, the magnetic shielding ring 150 is located on the side of the magnetic conductive ring 350 close to the infrared temperature measuring device 340 and is located inside the coil disk 330, that is, the magnetic shielding ring 150 is located inside the magnetic conductive ring 350, and the magnetic shielding ring 150 and the magnetic conductive ring 350 are not arranged relative to each other in the vertical direction, that is, the two are staggered in the vertical direction. In this case, the shortest distance between the outer ring surface of the magnetic shielding ring 150 and the corresponding inner ring surface of the magnetic conductive ring 350 is the width of the gap between the magnetic shielding ring 150 and the magnetic conductive ring 350, as shown in FIG. Figure 16 As shown in H in the figure, therefore, by limiting the shortest distance between the outer ring surface of the magnetic shielding ring 150 and the corresponding inner ring surface of the magnetic conductive ring 350 to be less than or equal to 4 mm, specifically, such as 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, or other values ​​that meet the requirements, the electromagnetic radiation will not be radiated into the detection cavity 140 and the through hole 321 through the gap, and will not interfere with the accuracy of temperature measurement by the infrared temperature measuring device 340, that is, the interference of the electromagnetic radiation on the temperature measurement accuracy of the infrared temperature measuring device 340 can be effectively eliminated.

[0108] When the magnetic shielding ring 150 or the magnetic conducting ring 350 is a polygon or other irregular structure or is arranged off-axis, the magnetic shielding ring 150 and the magnetic conducting ring 350 should be matched with each other and the gap therebetween meets the requirement of 4mm. For example, when the magnetic shielding ring 150 and the magnetic conducting ring 350 are arranged off-axis, based on the lowest point height of the magnetic shielding ring 150 of the pot 100 being higher than or equal to the highest point height of the magnetic conducting ring 350, in an embodiment, with the axis of the magnetic shielding ring of the pot 100 as a reference axis, the distance from the part of the outer ring surface of the magnetic shielding ring 150 of the pot 100 to the reference axis is greater than the distance from the inner ring surface of the magnetic conducting ring 350 to the reference axis, and the distance from the part of the outer ring surface of the magnetic shielding ring 150 to the reference axis is less than the distance from the inner ring surface of the magnetic conducting ring 350 to the reference axis, that is, the magnetic shielding ring 150 or the magnetic conducting ring 350 is arranged staggered, and the vertical direction and the oblique direction gap of the opposite surface of the magnetic conducting ring 350 close to the magnetic shielding ring 150 should be less than 4mm; for other asymmetric or irregular cases, they are not listed one by one here.

[0110] Specifically, in order to further reduce the interference of the coil disc 330 on the temperature measurement accuracy of the infrared temperature measuring device 340, by reasonably setting the gap width between the magnetic conducting ring 350 and the magnetic shielding ring 150 of the pot to be less than or equal to 2mm, such as 0mm, 1mm, 1.5mm, 2mm or other values meeting the requirements, the temperature measurement accuracy of the infrared temperature measuring device 340 can be greatly improved.

[0111] In some possible implementation embodiments provided by the present application, as Figures 8 to 13As shown, the electromagnetic cooker 300 further comprises a first mounting member 360 and a second mounting member 370, the inside of the shell 310 is provided with a mounting cavity 311 in communication with the through hole 321, the magnetic conducting ring 350 is arranged around the inner wall of the mounting cavity 311, i.e. the infrared temperature measuring device 340 is arranged in the inside of the mounting cavity 311. The infrared temperature measuring device 340 comprises a first part 342 and a second part 343 distributed along the height direction, the first part 342 comprises a window 341, i.e. the first part 342 is arranged close to the pot 100, the second part 343 is arranged away from the pot 100, and the first mounting member 360 is arranged between the first part 342 and the magnetic conducting ring 350 for filling the gap between the first part 342 and the magnetic conducting ring 350, so that the first part 342 of the infrared temperature measuring device 340 can be reliably connected with the magnetic conducting ring 350, at the same time, the top of the first mounting member 360, the top of the magnetic conducting ring 350, the top of the infrared temperature measuring device 340 and the top of the panel 320 are located in the same plane and form a complete plane structure, so that the surface of the electromagnetic cooker 300 in contact with the pot 100 is a plane structure or substantially a plane structure, i.e. the surface of the electromagnetic cooker 300 in contact with the pot 100 has no pits and cannot remain foreign matter, which is convenient for the user to clean the panel 320 of the electromagnetic cooker 300, at the same time, it is convenient for the storage of the electromagnetic cooker 300 and improves the user's satisfaction. It can be understood that the first mounting member 360 can be a gasket, a bracket, an adhesive or other structures meeting the requirements, which are not limited in the present application.

Since the heat generated by the pot 100 will accumulate above the infrared temperature measuring device 340, which will affect the accuracy of temperature measurement of the infrared temperature measuring device 340 or damage the infrared temperature measuring device 340 due to high temperature, the airflow in the mounting cavity 311 can be transmitted to the external environment through the air duct 313 and the air outlet 312 by the working of the fan 380, thereby realizing ventilation and heat dissipation of the infrared temperature measuring device 340, so as to improve the service life and the accuracy of temperature measurement of the infrared temperature measuring device 340.

[0114] Further, the second mounting member 370 is a heat-conducting member, that is, the second mounting member 370 is a member made of heat-conducting material, for example, the second mounting member 370 is a member made of aluminum, copper, or other materials meeting the requirements, and the heat of the infrared temperature measuring device 340 can be guided to the inside of the mounting cavity 311 or the inside of the air duct 313 through the second mounting member 370, and then the heat can be transmitted to the external environment through the air outlet 312 by the working of the fan 380, thereby realizing ventilation and heat dissipation of the infrared temperature measuring device 340. The second mounting member 370 is a heat-conducting member, which is beneficial to improve the cooling and heat dissipation speed of the infrared temperature measuring device 340 and ensure good cooling and heat dissipation effect, further improve the service life and the accuracy of temperature measurement of the infrared temperature measuring device 340, and improve the reliability of the cooking system 200.
