However, in these technologies, the detection device can easily be triggered by objects other than the pot to start the heating element, causing false activation and posing a safety risk. Summary of the Invention

[0004] Therefore, embodiments of the present invention provide a cooking appliance that can accurately detect the pot body and is highly safe.

[0008] The sensing component includes a magnetic element and a magnetic sensor. The magnetic element is disposed in the pot body, and at least a portion of the magnetic sensor is fitted into the through hole. When the distance between the magnetic sensor and the magnetic element is less than or equal to a preset distance, the magnetic sensor is used to emit an electrical signal, and the heating element can be turned on when the magnetic sensor emits an electrical signal.

[0009] The cooking appliance of this invention, through the cooperation of a magnetic component and a magnetic sensor, ensures that the magnetic sensor only emits an electrical signal when the distance between the magnetic component on the pot body and the magnetic sensor is within the sensing range of the magnetic sensor. This activates or prepares to activate the heating element to heat or prepare to heat the pot body, ensuring that the heating element can only be activated when the pot body of the cooking appliance (e.g., a dedicated pot) is close to the magnetic sensor. This reduces the possibility of accidental activation of the heating element, ensures the safety of the cooking appliance during use, improves the user experience, and the detection method is simple and easy to operate.

[0011] The cooking appliance of this invention has a shell that protects the sensing element, preventing the pot body from directly contacting the magnetic sensing element when they are within a preset distance range, thus ensuring the lifespan of the sensing element.

[0012] Optionally, the housing includes a housing body and a pressure plate, the housing body having a receiving groove with an opening at the lower end, the pressure plate being disposed at the lower end of the housing body to cover the receiving groove, and at least a portion of the sensing element extending through the pressure plate into the receiving groove.

[0013] The cooking appliance of this invention has a receiving groove with an opening at the lower end, which facilitates the installation of the sensor inside the outer shell. The pressure plate covers the receiving groove to ensure that the sensor is installed firmly inside the receiving groove and to protect the sensor that extends into the receiving groove.

[0014] Optionally, the magnetic sensor further includes a protective pad disposed within the receiving groove and located between the bottom surface of the receiving groove and the upper end of the sensing element.

[0015] The cooking appliance of this invention, by setting a protective pad, prevents the sensor from directly contacting the bottom surface of the receiving tank, ensuring that the sensor is not easily damaged and improving the service life of the sensor.

[0016] Optionally, the magnetic sensor further includes a fastener located inside the housing and connected to the sensing element, wherein the outer peripheral surface of the sensing element has a flange located on the side of the pressure plate away from the housing body and abutting against the pressure plate.

[0017] In the cooking appliance of this invention, the fastener is located inside the outer shell and connected to the sensing element, ensuring that the sensing element is firmly installed inside the outer shell. The flange abuts against the side of the pressure plate away from the shell body, further ensuring that the sensing element is firmly installed inside the outer shell.

[0018] Optionally, the magnetic sensor is a Hall sensor.

[0019] The cooking appliance of this invention has a simple structure, is easy to obtain, and saves costs due to the simple structure of the magnetic induction element.

[0020] Optionally, the cooking appliance further includes a switch assembly, which is connected in series with the heating element and includes a conductive element. The conductive element can move under the action of the pot body to turn on the switch assembly. The heating element can be activated when the magnetic sensor emits an electrical signal and the switch assembly is turned on.

[0021] The cooking appliance of this invention achieves dual detection through a sensing component and a switching component. The heating element can only be activated when the magnetic sensor emits an electrical signal and the switching component is turned on. This can effectively prevent the heating element from being activated accidentally, further ensuring the safety of the cooking appliance during use and improving the user experience.

[0022] Optionally, the switch assembly further includes a moving block that can move downward under the action of the pot body to push the conductive element, thereby turning on the switch assembly.

[0023] The cooking appliance of this invention uses a moving block to push the conductive component, which avoids direct contact between the pot body and the conductive component, ensuring that the conductive component is not easily damaged by external forces, thus improving safety. Moreover, the operation is simple.

[0024] Optionally, the moving block has a first inclined surface, and the switch assembly further includes a push rod having a second inclined surface that cooperates with the first inclined surface. The push rod can move along a first direction under the drive of the moving block to push the conductive element, and the first direction is orthogonal to the up and down direction.

[0025] The cooking appliance of this invention, through the cooperation of the inclined surface of the moving block and the inclined surface of the push rod, the downward movement of the moving block can push the push rod to move along the first direction to push the conductive element to turn on the switch assembly, making the way the conductive element turns on the switch assembly simple, and can shorten the size of the switch assembly in the vertical direction, and improve the compactness of the cooperation between the various parts of the switch assembly.

[0026] Optionally, the switching assembly further includes:

[0027] A first elastic element, configured to drive the moving block upward to reset; and / or

[0028] A second elastic element is used to drive the push rod to move in a second direction opposite to the first direction to reset the conductive element and thereby disconnect the switch assembly.

[0029] In the cooking appliance of this invention, when the pot body moves away from the moving block, the pressure exerted by the pot body on the moving block disappears. The first elastic element can push the moving block upward under the action of its own elastic force, thereby improving the reset efficiency of the moving block. After the force exerted by the moving block on the push rod disappears, the second elastic element pushes the push rod to move in the second direction under the action of its own elastic force, thereby timely disconnecting the switch assembly, ensuring the safety of using the cooking appliance, and improving the coordination and automation of the switch assembly.

[0031] In the cooking appliance of this invention, the top of the moving block can extend out of the mounting hole, which facilitates the contact between the pot body and the moving block to push the moving block to move. The first elastic element is located in the mounting hole, which can limit the first elastic element and ensure that the first elastic element is not easily deflected when compressed or reset. The first elastic element abuts between the bottom end of the moving block and the stop part to ensure that the first elastic element is installed firmly. The push rod is located in the base to ensure that the push rod is not easily moved by external force and improve safety.

[0032] Optionally, the switch assembly further includes a support plate, on which the push rod, the conductive element, and the second elastic element are all disposed, and the support plate is disposed on the base.

[0033] The cooking appliance of this invention has a support plate that facilitates the installation of the push rod, conductive component, and second elastic component. The support plate is located inside the base, which ensures that the support plate is not easily affected by external forces and improves the safety of the support plate during operation.

[0034] Optionally, the second elastic element is a torsion spring, the push rod is provided with a first mating groove, the support plate is provided with a second mating groove, one end of the second elastic element abuts in the first mating groove, and the other end of the second elastic element is mated in the second mating groove.

[0035] The cooking appliance of this invention, through the above-described configuration, has a simple structure for the second elastic member, and ensures that the second elastic member is firmly installed on the support plate, which can effectively push the push rod to move and improve the efficiency of the push rod movement.

[0036] Optionally, the switch assembly further includes a guide disposed on the support plate, the push rod passing through the guide, the end of the push rod adjacent to the conductive element having a protrusion, and the end of the protrusion away from the conductive element abutting against the guide to limit the push rod when it moves in the second direction.

Detailed Implementation

[0053] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0054] like Figures 1-12 As shown, the cooking appliance of this embodiment includes a pot body 1, a heating element 2, and a sensing component 3. The heating element 2 is disposed below the pot body 1 for heating the pot body 1, and the heating element 2 has a through hole 21. The sensing component 3 includes a magnetic element 31 and a magnetic sensor 32. The magnetic element 31 is disposed on the pot body 1, and at least a portion of the magnetic sensor 32 is fitted into the through hole 21. When the distance between the magnetic sensor 32 and the magnetic element 31 is less than or equal to a preset distance, the magnetic sensor 32 emits an electrical signal, and the heating element 2 can be turned on when the magnetic sensor 32 emits an electrical signal.

[0055] In this embodiment of the invention, the cooking appliance, through the cooperation of the magnetic component 31 and the magnetic sensor 32, ensures that the magnetic sensor 32 only emits an electrical signal when the distance between the magnetic component 31 and the magnetic sensor 32 on the pot body 1 is within the sensing range of the magnetic sensor 32. This activates or prepares to activate the heating component 2 to heat or prepare to heat the pot body 1. This ensures that the heating component 2 can only be activated when the pot body 1 of the cooking appliance 100 (e.g., a dedicated pot) is close to the magnetic sensor 32, reducing the possibility of accidental activation of the heating component 2, ensuring the safety of the cooking appliance 100 during use, improving the user experience, and the detection method is simple and easy to operate.

[0056] Specifically, such as Figures 1-4As shown, the through hole 21 is located in the middle of the heating element 2. The magnetic element 31 is located in the middle of the bottom surface of the pot body 1 and is arranged corresponding to the through hole 21, which improves the induction intensity between at least part of the magnetic sensor 32 and the magnetic element 31 through the through hole 21. The magnetic element 31 can be a magnet, and preferably a neodymium iron boron magnet.

[0057] Optionally, such as Figures 2-4 As shown, the magnetic sensor 32 includes a housing 321 and a sensing element 322. At least a portion of the housing 321 is located in the through hole 21, and at least a portion of the sensing element 322 extends through the housing 321 into the housing 321.

[0058] Specifically, the outer shell 321 can protect the sensor 322, preventing the pot body 1 from directly contacting the magnetic sensor 322 when the pot body 1 is within a preset distance range, thus ensuring the service life of the sensor 322.

[0059] Optionally, such as Figures 2-4 As shown, the outer casing 321 includes a casing body 3211 and a pressure plate 3212. The casing body 3211 has a receiving groove 3213 with an opening at the lower end. The pressure plate 3212 is disposed at the lower end of the casing body 3211 to cover the receiving groove 3213. At least a portion of the sensing element 322 extends into the receiving groove 3213 through the pressure plate 3212.

[0060] Specifically, the shell body 3211 has a receiving groove 3213 with an opening at the lower end, which facilitates the installation of the sensing element 322 inside the shell 321. The pressure plate 3212 covers the receiving groove 3213 to ensure that the sensing element 322 is installed firmly in the receiving groove 3213 and can protect the sensing element 322 that extends into the receiving groove 3213. In addition, the structure of the shell 321 is simple and saves manufacturing costs.

[0061] Specifically, such as Figures 2-4 As shown, the shell body 3211 has a protrusion 3214, which protrudes upward from the bottom surface of the shell body 3211. A receiving groove 3213 is formed inside the protrusion 3214, and the protrusion 3214 is located in the through hole 21. The outer edge of the shell body 3211 has an upward-curved portion 3215, which abuts against the bottom surface of the heating element 2 to ensure that the shell body 3211 is firmly installed. The outer edge of the pressure plate 3212 is turned upward and wraps around the outer peripheral surface of the upward-curved portion 3215, which improves the fit between the pressure plate 3212 and the shell body 3211.

[0062] Optionally, such as Figures 2-4 As shown, the magnetic sensor 32 also includes a protective pad 323, which is disposed in the receiving groove 3213 and located between the bottom surface of the receiving groove 3213 and the upper end of the sensing element 322.

[0063] Specifically, the protective pad 323 is made of silicone and is located between the bottom surface of the receiving groove 3213 and the upper end of the sensing element 322, so that the sensing element 322 is not easily in direct contact with the bottom surface of the receiving groove 3213, ensuring that the sensing element 322 is not easily damaged and improving the service life of the sensing element 322.

[0064] Optionally, such as Figures 2-4 As shown, the magnetic sensor 32 also includes a fastener 324, which is located inside the housing 321 and connected to the sensing element 322. The outer peripheral surface of the sensing element 322 has a flange 325, which is located on the side of the pressure plate 3212 away from the housing body 3211 and abuts against the pressure plate 3212.

[0065] Specifically, the fastener 324 is a nut, the outer peripheral surface of the portion of the sensing element 322 located in the receiving groove 3213 has external threads, the fastener 324 is located in the receiving groove 3213 and is threadedly engaged with the portion of the sensing element 322 located in the receiving groove 3213, ensuring that the sensing element 322 is firmly installed in the housing 321, and the flange 325 abuts against the side of the pressure plate 3212 away from the housing body 3211, further improving the firmness of the sensing element 322 installed in the housing 321.

[0066] Optionally, the magnetic sensor 32 is a Hall sensor, which has a simple structure, is easy to obtain, and saves costs.

[0067] Optionally, such as Figure 1 , Figure 2 and Figure 5 As shown, the cooking appliance 100 also includes a switch assembly 4, which is connected in series with the heating element 2 and includes a conductive element 41. The conductive element 41 can move under the action of the pot body 1 to turn on the switch assembly 4. The heating element 2 can be activated when the magnetic sensor 32 sends an electrical signal and the switch assembly 4 is turned on.

[0068] Specifically, dual detection is achieved through the sensing component 3 and the switching component 4. The heating element 2 can only be started when the magnetic sensor 32 emits an electrical signal and the switching component 4 is turned on. This can effectively prevent the heating element 2 from being started accidentally, further ensuring the safety of the cooking appliance 100 during use and improving the user experience.

[0069] Optionally, such as Figure 2 , Figures 7-12 As shown, the switch assembly 4 also includes a moving block 42. The moving block 42 can move downward under the action of the pot body 1 to push the conductive element 41. The moving block 42 pushes the conductive element 41 to turn on the switch assembly 4.

[0070] Specifically, the pot body 1 pushes the conductive component 41 through the moving block 42, which can avoid direct contact between the pot body 1 and the conductive component 41, ensuring that the conductive component 41 is not easily damaged by external forces, improving safety, and the operation method is simple.

[0071] Optionally, such as Figures 5-12 As shown, the moving block 42 has a first inclined surface 421, and the switch assembly 4 also includes a push rod 43. The push rod 43 has a second inclined surface 431 that cooperates with the first inclined surface 421. The push rod 43 can move along a first direction to push the conductive element 41 under the drive of the moving block 42. The first direction is orthogonal to the up and down direction.

[0072] Specifically, through the cooperation of the first inclined surface 421 of the moving block 42 and the second inclined surface 431 of the push rod 43, the downward movement of the moving block 42 can push the push rod 43 to move along the first direction to push the conductive element 41 to conduct the switch assembly 4, making the way the conductive element 41 conducts the switch assembly 4 simple, and can shorten the size of the switch assembly 4 in the vertical direction, and improve the compactness of the cooperation between the various parts of the switch assembly 4.

[0073] It is understood that the positional relationship of the moving block 42, the push rod 43, and the conductive element 41 is not limited to the above-described form. Alternatively, the moving block 42, the push rod 43, and the conductive element 41 can be arranged sequentially in a vertical direction. The downward movement of the moving block 42 can push the push rod 43 downward to activate the conductive element 41 and turn on the switch assembly 4. Or, in another embodiment, the downward movement of the moving block 42 can directly push the conductive element 41 to turn on the switch assembly 4.

[0074] Optionally, such as Figures 9-12 As shown, the switch assembly 4 also includes a first elastic element 44, which is used to drive the moving block 42 to move upward to reset.

[0075] Specifically, when the pot body 1 moves away from the moving block 42, the pressure applied by the pot body 1 to the moving block 42 disappears, and the first elastic element 44 can push the moving block 42 upward under the action of its own elastic force, thereby improving the reset efficiency of the moving block 42.

[0076] Optionally, such as Figures 9-12 As shown, the switch assembly 4 also includes a second elastic element 45, which is used to drive the push rod 43 to move in a second direction opposite to the first direction to reset the conductive element 41 and thus disconnect the switch assembly 4.

[0077] Specifically, after the force applied by the moving block 42 to the push rod 43 disappears, the second elastic element 45 pushes the push rod 43 to move in the second direction under its own elastic force, so as to disconnect the switch assembly 4 in time, ensure the safety of using the cooking appliance 100, and improve the coordination and automation of the switch assembly 4.

[0078] Specifically, the first elastic element 44 is a spring, which has a simple structure and saves costs.

[0079] Optionally, such as Figure 1 and Figure 2 As shown, the cooking appliance 100 also includes a base 5, on which the pot body 1 can be placed. The top of the base 5 is provided with a mounting hole 52, and the bottom of the mounting hole 52 is provided with a stop portion 521. At least a portion of the switch assembly 4 is located in the mounting hole 52. The top of the moving block 42 can extend out of the mounting hole 52. The pot body 1 can abut against the top of the moving block 42. The first elastic member 44 is located in the mounting hole 52 and abuts between the bottom of the moving block 42 and the stop portion 521. The push rod 43 is located in the base 5.

[0080] Specifically, the top of the moving block 42 can extend out of the mounting hole 52, which facilitates the contact between the pot body 1 and the moving block 42 to push the moving block 42 to move. The first elastic member 44 is located in the mounting hole 52, which can limit the first elastic member 44 and ensure that the first elastic member 44 is not easily deflected when compressed or reset. The first elastic member 44 abuts between the bottom end of the moving block 42 and the stop part 521 to ensure that the first elastic member 44 is installed firmly. The push rod 43 is located in the base 5 to ensure that the push rod 43 is not easily moved by external forces and improves safety.

[0081] It is understandable that when the pot body 1 and the base 5 are separate, the pot body 1 can abut against the moving block 42 when placed on the base 5, and the moving block 42 is driven to move downward under the gravity of the pot body 1 itself.

[0082] In another embodiment, when the pot body 1 and the base 5 are integral, the pot body 1 is connected to the base 5 and can move up and down relative to the base 5. When enough food is put into the pot body 1, the moving block 42 is driven to move down under the gravity of the food and the pot body 1.

[0083] Specifically, mounting holes 52 are located on the outer periphery of the top of the base 5, and there are at least two mounting holes 52, which are evenly spaced circumferentially along the outer periphery of the top of the base 5. The moving block 42 is adjacent to the outer periphery of the base 5 relative to the push rod 43, so that the pot body 1 not only has the magnetic element 31, but can also simultaneously abut against the moving block 42, making the pot body 1 unique and improving the safety and user experience of the cooking utensil 100 during use.

[0084] In some embodiments, when the mounting hole 52 is a blind hole, the mounting hole 52 has a bottom wall surface, and the bottom wall surface of the mounting hole 52 forms a stop portion 521. In other embodiments, the bottom of the mounting hole 52 has a stop member, and the stop member forms a stop portion 521.

[0085] Optionally, such as Figure 5 As shown, the switch assembly 4 also includes a support plate 46, and the push rod 43, the conductive element 41, and the second elastic element 45 are all disposed on the support plate 46. The support plate 46 is disposed on the base 5.

[0086] Specifically, the support plate 46 facilitates the installation of the push rod 43, the conductive element 41, and the second elastic element 45, thereby improving the tightness of the fit between the components in the switch assembly 4. The support plate 46 is located inside the base 5, ensuring that the support plate 46 is not easily affected by external forces and improving the safety of the support plate 46 during operation.

[0087] Specifically, the top of the base 5 has an annular plate 51 with mounting holes 52. The lower end of the first elastic member 44 abuts against the base 5, and the upper end of the first elastic member 44 abuts against the bottom end of the moving block 42. The bottom surface of the annular plate 51 has a recess 511, a support plate 46 is disposed in the recess 511, and the push rod 43 and the conductive member 41 are disposed on the side of the support plate 46 away from the annular plate 51.

[0088] Optionally, such as Figures 9-12 As shown, the second elastic element 45 is a torsion spring. The push rod 43 is provided with a first mating groove 432, and the support plate 46 is provided with a second mating groove 462. One end of the torsion spring abuts in the first mating groove 432, and the second end of the torsion spring is mated in the second mating groove 462.

[0089] Specifically, the second elastic element 45 is a torsion spring, which has a simple structure and saves costs. The bottom surface of the support plate 46 is provided with a protrusion 461, and the second mating groove 462 is provided on the side of the protrusion 461 adjacent to the push rod 43. One end of the second elastic element 45 abuts in the first mating groove 432, and the other end of the second elastic element 45 is fitted in the second mating groove 462, ensuring that the second elastic element 45 is firmly installed on the support plate 46, which can effectively push the push rod 43 to move and improve the moving efficiency of the push rod 43.

[0090] Specifically, a locking part 433 is provided on the inner wall surface of the first mating groove 432 away from the conductive component 41. One end of the torsion spring abuts against the first mating groove 432 and is located between the bottom surface of the first mating groove 432 and the locking part 433, ensuring that one end of the torsion spring is firmly installed in the first mating groove 432.

[0091] Optionally, such as Figure 5 and Figure 6 As shown, the switch assembly 4 also includes a guide 47, which is disposed on the support plate 46. The push rod 43 passes through the guide 47. The end of the push rod 43 adjacent to the conductive element 41 has a protrusion 434. The end of the protrusion 434 away from the conductive element 41 can abut against the guide 47 to limit the push rod 43 when it moves in the second direction.

[0092] Specifically, there are at least two guide members 47, which are arranged at intervals along the first direction on the bottom surface of the support plate 46. The push rod 43 passes through at least two guide members 47 in sequence. The guide members 47 can guide the movement of the push rod 43, ensuring that the push rod 43 moves stably and can accurately push the conductive member 41. The protrusion 434 abuts against the guide member 47, ensuring that the push rod 43 does not easily detach from the guide member 47 when it moves toward the second direction.
