[0060] Please see Figures 1 to 8 The present invention provides a cooking appliance 500 comprising a lid assembly, a pot body 200, and a detection component. The lid assembly includes a lid 300 and a switching component 150, the switching component 150 being disposed on the lid 300. The pot body 200 is connected to the lid 300, and a cooking cavity 250 is formed within the pot body 200, the lid 300 covering the cooking cavity 250.

[0061] The switching assembly 150 includes a first sealing plate 32 and a second sealing plate 33. The first sealing plate 32 is provided with a steam vent 34. The second sealing plate 33 can move back and forth between a first position and a second position relative to the first sealing plate 32. When the second sealing plate 33 is in the first position, the second sealing plate 33 closes the steam vent 34 to seal the cooking chamber 250. When the second sealing plate 33 is in the second position, the second sealing plate 33 opens the steam vent 34 to allow the cooking chamber 250 to communicate with the outside of the cooking chamber 250 through the steam vent 34.

[0062] The detection assembly includes a detection element 11, which is connected to the second sealing sheet 33 and can move with the second sealing sheet 33. The detection assembly is configured to determine whether the second sealing sheet 33 is in a first position or a second position by detecting the position of the detection element 11.

[0063] In the cooking appliance 500 described above, the detection component determines the position of the second sealing plate 33 by detecting the position of the detection element 11, thereby determining the sealing state of the cooking cavity 250, which is beneficial for the cooking appliance 500 to work in the correct cooking mode.

[0064] Specifically, the cooking appliance 500 can operate in both pressurized and unpressurized cooking modes. In pressurized cooking mode, the second sealing plate 33 can move to the first position, and the switching component 150 can close the vent 34, sealing the cooking chamber 250, thereby allowing pressurized cooking of the food. In unpressurized cooking mode, the second sealing plate 33 can move to the second position, and the switching component 150 can open the vent 34, connecting the cooking chamber 250 to the outside environment, thereby allowing unpressurized cooking of the food.

[0065] Cooking appliances 500 include, but are not limited to, pressure cookers, electric pressure cookers, pressure slow cookers, etc. Figure 1 and Figure 5 As shown, the cooking appliance 500 includes a lid assembly and a pot body 200. When closed, the lid assembly and pot body 200 fit tightly together via a sealing ring, forming a relatively enclosed cooking cavity 250 inside. When the vent 34 is closed and the cooking appliance 500 begins to operate, the food inside the cooking cavity 250 is heated, the water inside the cooking cavity 250 begins to evaporate, and the amount of steam generated gradually increases, causing the pressure inside the cooking cavity 250 to gradually rise. Because the cooking cavity 250 is sealed at this time, the steam cannot escape from the cooking appliance 500, resulting in the pressure inside the cooking cavity 250 being maintained, thereby increasing the boiling point of the water and accelerating the cooking process.

[0066] To provide more cooking options and flexibility to meet different ingredients and cooking needs, cooking appliances 500 often include a pressure-free cooking mode. However, due to mechanical wear, operational errors, or design flaws, the switching mechanism may fail to switch successfully during actual operation. This means that when the user needs to switch cooking modes, the switching mechanism may not be properly engaged. Therefore, pressure cookers with a pressure-free cooking mode may fail to switch successfully between pressure cooking and pressure-free cooking modes, causing the electric pressure cooker to operate in the wrong cooking mode and reducing the user experience.

[0067] In this embodiment of the invention, the detection component includes a detection element 11, which is connected to the second sealing sheet 33. By detecting the position of the detection element 11, the detection component determines whether the second sealing sheet 33 is in a first position or a second position, thereby determining whether the cooking appliance 500 is currently in a pressurized cooking mode or a pressureless cooking mode.

[0068] Optionally, in one embodiment, the cooking appliance 500 may have LED indicator lights of different colors on its casing. For example, a red indicator light indicates a pressurized cooking mode, and a green indicator light indicates a pressureless cooking mode. After the detection component determines the current cooking mode, it will trigger the corresponding indicator light to illuminate, so that the user can intuitively understand the current cooking mode. In one embodiment, the cooking appliance 500 includes a display screen that can directly display the current cooking mode. After the detection component determines the mode, it transmits the mode information to the display screen, which will display text or icons such as "pressurized cooking mode" or "pressureless cooking mode" in real time.

[0069] In some embodiments, the first sealing sheet 32 ​​and the second sealing sheet 33 are connected by close surface contact.

[0070] Therefore, when the second sealing plate 33 is in the first position, the second sealing plate 33 closes the vent hole 34 by making close contact with the first sealing plate 32. Optionally, during the movement of the second sealing plate 33 relative to the first sealing plate 32, the first sealing plate 32 and the second sealing plate 33 can also maintain a close contact state.

[0071] Surface contact includes, but is not limited to, regular or irregular surface contact such as planar (horizontal or inclined) contact, arc surface contact, conical surface contact, frustum side contact, wavy surface contact, sawtooth surface contact, and square wave surface contact. In the embodiment shown in the figure, the surface contact is planar contact.

[0072] Optionally, in one embodiment, the cooking appliance 500 can be switched to a pressure cooking mode or a pressureless cooking mode before cooking.

[0073] Optionally, in one embodiment, the cooking appliance 500 can switch from a pressurized cooking mode to a pressureless cooking mode, or from a pressureless cooking mode to a pressurized cooking mode, during the cooking process.

[0074] Optionally, in one embodiment, the cooking appliance 500 can switch from a pressurized cooking mode to a pressureless cooking mode or vice versa during the cooking process, and can also switch to a pressurized cooking mode or a pressureless cooking mode before cooking.

[0075] In one embodiment, the pressureless cooking described in this invention refers to a pressure within the cooking chamber 250 of the cooking appliance 500 being less than or equal to 4 kPa during operation. The venting area of ​​the vent 34 can be understood as the opening area of ​​the vent 34. In one embodiment, when the vent 34 is fully open, the entire venting area of ​​the vent 34 is used for venting steam, enabling the pressure cooking appliance 500 to achieve pressureless cooking. In another embodiment, when the vent 34 is partially open, a portion of the venting area of ​​the vent 34 is used for venting steam, enabling the pressure cooking appliance 500 to achieve pressureless cooking.

[0076] When the vent 34 is opened to a certain size (fully or partially), the vent area of ​​the vent 34, which enables pressure cooking 500 to achieve pressureless cooking, is related to the power of the pressure cooking appliance 500. Generally, the higher the power of the pressure cooking appliance 500, the larger the opening area of ​​the vent 34 required for pressureless cooking. The opening area of ​​the vent 34 corresponding to pressureless cooking at a certain power of the pressure cooking appliance 500 can be determined through simulation, testing, and empirical values.

[0077] In some implementations, please refer to Figures 1 to 8 The detection element 11 includes a magnet, and the detection assembly includes a magnetic switch 12, which is used to detect the position of the magnet by detecting the magnetic field of the magnet.

[0078] In the above embodiments, by means of the cooperation of the magnet and the magnetic switch 12, the detection component can accurately detect the position of the second sealing plate 33 to a certain extent, thereby determining the sealing status of the cooking cavity 250, which is beneficial for the cooking appliance 500 to work in the correct cooking mode.

[0079] Specifically, a magnet is a magnetic material that can generate a magnetic field. The magnet is connected to the second sealing plate 33. As the second sealing plate 33 moves between a first position and a second position, the position of the magnet also changes accordingly.

[0080] Magnetic switch 12 (also known as a reed switch) is a component that uses a magnetic field to control the switching of a circuit. When a magnet approaches magnetic switch 12, the magnet's magnetic field acts on the metal reed inside magnetic switch 12, causing it to close and thus making the circuit conductive. Conversely, when the magnet moves away from magnetic switch 12, the magnet's magnetic field disappears, the metal reed returns to its original position, and the circuit is disconnected.

[0081] Because the cooking appliance 500 requires high temperatures and generates a large amount of water vapor during cooking, it may face a high-temperature and high-humidity environment. The magnet and magnetic switch 12 have good vibration resistance and temperature resistance, ensuring normal operation under various working conditions.

[0082] In this embodiment of the invention, the magnetic switch 12 can detect the magnetic field of the magnet. When the magnet is close to the magnetic switch 12, the magnetic field strength is relatively large, the magnetic switch 12 is triggered, and the second sealing plate 33 is detected to be in the first position. The cooking appliance 500 is then in a pressurized cooking mode. Figure 2 and Figure 6 As shown. When the magnet moves away from the magnetic switch 12, the magnetic field strength gradually weakens until the magnetic field disappears, and the magnetic switch 12 is not triggered. The detection component thus determines that the second sealing plate 33 has moved to the second position, and the cooking appliance 500 is in a pressure-free cooking mode, such as... Figure 3 and Figure 7 As shown.

[0083] Optionally, in one embodiment, when the second sealing plate 33 is in the first position, that is, when the magnet is in the position corresponding to the first position, the second sealing plate 33 closes the vent hole 34 on the first sealing plate 32 to seal the cooking cavity 250, the magnetic switch 12 and the magnet are close to each other, and the cooking appliance 500 is in a pressurized cooking mode.

[0084] In one embodiment, when the second sealing plate 33 is located between the first position and the second position, that is, when the magnet is located between the position corresponding to the first position and the position corresponding to the second position, the second sealing plate 33 opens a portion of the vent hole 34 on the first sealing plate 32, allowing the cooking chamber 250 to communicate with the outside world through the vent hole 34. The magnetic switch 12 moves away from the magnet, and the cooking appliance 500 is in an intermediate state between the pressurized cooking mode and the pressureless cooking mode.

[0085] In one embodiment, when the second sealing plate 33 is in the second position, that is, when the magnet is in the position corresponding to the second position, the second sealing plate 33 opens the vent hole 34 on the first sealing plate 32 so that the cooking cavity 250 is connected to the outside of the cooking cavity 250 through the vent hole 34, the magnetic switch 12 is further away from the magnet, and the cooking appliance 500 is in a pressureless cooking mode.

[0086] This embodiment of the invention does not specifically limit the number of magnetic switches 12 and magnets. In one example, there are two magnetic switches 12 and two magnets. Magnetic switches 12 at different positions can correspond to the first position and the second position of the second sealing plate 33, respectively. By triggering the magnetic switch 12 at the corresponding position with the magnet at the corresponding position, the position of the second sealing plate 33 can be obtained. In one example, there is one magnetic switch 12 and one detection element 11.

[0087] Optionally, in other embodiments, the detection element 11 includes a reflective film, and the detection assembly includes a photodetector. The reflective film is connected to the second sealing sheet 33 and moves with the movement of the second sealing sheet 33. The photodetector is used to detect the position of the reflective film by detecting whether the reflective film reflects the light emitted by the photodetector, thereby obtaining the position of the second sealing sheet 33.

[0088] In some implementations, please refer to Figures 1 to 4 The pot lid assembly includes a mounting cover 30 and a first operating member 41. The pot lid 300 is rotatable relative to the mounting cover 30. A portion of the detection component is disposed on the mounting cover 30. The first operating member 41 is rotatably disposed on the mounting cover 30 and connects the second sealing plate 33 and the pot lid 300. When the first operating member 41 rotates, it drives the second sealing plate 33 and the pot lid 300 to rotate, so that the second sealing plate 33 switches between a first position and a second position, and locks and unlocks the pot lid 300 and the pot body 200.

[0089] In the above embodiments, by rotating the first operating member 41, the second sealing plate 33 and the pot lid 300 can be rotated simultaneously, so that the second sealing plate 33 can switch between the first position and the second position, realizing the conversion between pressurized and pressureless cooking modes. At the same time, the pot lid 300 can be locked and unlocked with the pot body 200, realizing the function of closing and opening the pot lid 300. This increases the functionality of the cooking appliance 500, saves space for the pot lid 300 to a certain extent, improves the integration of the product, and reduces manufacturing costs.

[0090] Specifically, in this embodiment of the invention, the detection component includes a magnetic switch 12, which is disposed on the mounting cover 30.

[0091] Alternatively, in one implementation, please combine Figure 15 and Figure 17The pot lid assembly includes a lid opening component 50, which is rotatably connected to the pot lid 300 via a connecting slider 13. The lid opening component 50 includes a limiting post 47. The first operating component 41 is provided with a first limiting hole 48, and the connecting slider 13 is provided with a second limiting hole 49. The connecting slider 13 is located between the first operating component 41 and the lid opening component 50. The limiting post 47 passes through the first limiting hole 48 and the second limiting hole 49. The first operating component 41 can be engaged with the connecting slider 13, thereby enabling the first operating component 41 to be rotatably mounted on the mounting cover 30.

[0092] Optionally, the switching component 150 includes a first connector 20, a first operating component 41 connected to the first connector 20, and the first connector 20 connected to the second sealing plate 33, thereby enabling the first operating component 41 to connect to the second sealing plate 33.

[0093] In this embodiment of the utility model, when the first operating member 41 rotates, it drives the second sealing plate 33 and the pot lid 300 to rotate, so that the second sealing plate 33 switches between a first position and a second position, thereby switching the cooking appliance 500 between a pressure cooking mode and a pressureless cooking mode, and locking and unlocking the pot lid 300 and the pot body 200, thereby switching the cooking appliance 500 between a closed mode and a screw-on mode.

[0094] In one embodiment, the lid 300 is used to cover the pot body 200. The lid 300 typically has multiple upper teeth, and the pot body 200 has multiple lower teeth. When the upper and lower teeth are rotated to align and abut, the lid 300 is closed to the pot body 200, thus locking the lid 300. When the upper and lower teeth are rotated to a misaligned position, the lid 300 can be opened to unlock the pot body 200.

[0095] The closed-lid mode refers to the situation where the upper teeth of the lid 300 and the lower teeth of the pot body 200 are aligned and abutting. The unscrewed mode refers to the situation where the upper teeth of the lid 300 and the lower teeth of the pot body 200 are misaligned and separated. The pressurized cooking mode refers to the second sealing plate 33 closing the vent hole 34 on the first sealing plate 32 to seal the cooking chamber 250. The pressureless cooking mode refers to the second sealing plate 33 fully opening the vent hole 34 on the first sealing plate 32, allowing the cooking chamber 250 to communicate with the outside through the vent hole 34. Figures 1 to 4 In this implementation, the closed-lid mode and the pressurized cooking mode are synchronized, and the open-lid mode and the pressureless cooking mode are synchronized.

[0096] The invention's description of unlocking the pot lid 300 from the pot body 200 by rotating the lid 300 refers to the following: with the upper jaw of the lid 300 aligned and abutting against the lower jaw of the pot body 200, the lid 300 is rotated around its central axis. This rotation causes the upper jaw of the lid 300 and the lower jaw of the pot body 200 to become misaligned and separate, thus unlocking the lid 300 from the pot body 200. The central axis of the lid 300 can extend vertically.

[0097] The locking of the pot lid 300 to the pot body 200 by rotating the pot lid 300 as described in this utility model can be understood as follows: when the upper jaw of the pot lid 300 and the lower jaw of the pot body 200 are misaligned and separated, the pot lid 300 is rotated around its central axis so that the upper jaw of the pot lid 300 and the lower jaw of the pot body 200 are rotated to be aligned and abutted, thereby achieving the locking of the pot lid 300 to the pot body 200.

[0098] In some implementations, please refer to Figures 1 to 4 The mounting cover 30 is provided with a through hole. The pot lid assembly includes a linkage slider 13 and a connecting block 14. The pot lid 300 is connected to the connecting block 14 through the through hole. The linkage slider 13 connects the first operating member 41 and the connecting block 14. The first operating member 41 drives the pot lid 300 to rotate through the linkage slider 13 and the connecting block 14.

[0099] In the above embodiment, the pot lid 300 and the linkage slider 13 can be connected by the connecting block 14, so that the pot lid 300 is connected to the first operating member 41, thereby realizing that the pot lid 300 rotates when the first operating member 41 is rotated.

[0100] Specifically, the linkage slider 13 is provided with a connecting hole, and correspondingly, the connecting block 14 is provided with a connecting post. The connecting hole of the linkage slider 13 is connected to the connecting post of the connecting block 14, and the connecting block 14 is connected to the pot lid 300 through a through hole.

[0101] In this embodiment of the utility model, when the first operating member 41 rotates, it acts on the limiting post 47 of the opening member 50 through the first limiting hole 48, causing the opening member 50 to rotate. The limiting post 47 of the opening member 50 acts on the second limiting hole 49 of the connecting slider 13, causing the connecting slider 13 to rotate. The connecting slider 13 drives the connecting post through the connecting hole, thereby driving the connecting block 14 to move, and then driving the pot lid 300 to rotate.

[0102] In some implementations, please refer to Figures 1 to 4 The mounting cover 30 is provided with a guide groove 15, a through hole is provided on the bottom surface of the guide groove 15, and a connecting block 14 is provided in the guide groove 15. The guide groove 15 is used to guide the movement of the connecting block 14.

[0103] In the above embodiment, the guide groove 15 restricts the movement of the connecting block 14, allowing it to slide smoothly within the guide groove 15, thereby ensuring that the connecting block 14 can accurately drive the pot lid 300 to rotate or move.

[0104] Specifically, the connecting block 14 can be connected to the pot lid 300 through the through hole, and the connecting block 14 is connected to the linkage slider 13 through the connecting post. When the linkage slider 13 rotates, the linkage slider 13 acts on the connecting post through the connecting hole, thereby driving the connecting block 14 to move in the guide groove 15.

[0105] In some implementations, please refer to Figures 1 to 4 The first operating member 41 is provided with a first tooth 16, and the switching component 150 includes a first connector 20, which is connected to a second sealing plate 33. The first connector 20 is provided with a second tooth 17, and the first tooth 16 meshes with the second tooth 17.

[0106] In the above embodiment, through the meshing of the teeth, the rotation of the first operating member 41 can be accurately transmitted to the first connecting member 20, thereby driving the second sealing plate 33 to rotate, realizing the switching of the cooking appliance 500 between the pressure cooking mode and the pressureless cooking mode.

[0107] Specifically, the switching assembly 150 includes an operating lever 40, a first connecting member 20 connected to the operating lever 40, and the operating lever 40 connected to a second sealing plate 33, thereby enabling the first connecting member 20 to connect to the second sealing plate 33. Optionally, the connection between the first connecting member 20 and the operating lever 40, and between the operating lever 40 and the second sealing plate 33, can be a fixed connection or a detachable connection, such as an adhesive connection, a slot connection, etc., and the connection between the two can be one that does not allow relative rotation.

[0108] In this embodiment of the utility model, when the first operating member 41 rotates, it drives the second tooth 17 to rotate through the first tooth 16, thereby driving the first connecting member 20 to rotate, and then driving the second sealing plate 33 to rotate, so as to realize the switching of the second sealing plate 33 between the first position and the second position.

[0109] In some implementations, please refer to Figures 9 to 14 The switching assembly 150 includes a valve housing 36 and an operating lever 40. The valve housing 36 has a receiving cavity 37. A first sealing plate 32 and a second sealing plate 33 are disposed in the receiving cavity 37. The receiving cavity 37 has a first opening 38 and a second opening 39 at its two ends, respectively. The first opening 38 faces the cooking cavity 250, and the second opening 39 faces away from the cooking cavity 250. The operating lever 40 connects the second sealing plate 33 and the first connecting member 20. The first connecting member 20 drives the second sealing plate 33 to rotate through the operating lever 40.

[0110] In the above embodiments, a robust receiving cavity 37 can be provided by the valve housing 36 to accommodate the first sealing plate 32 and the second sealing plate 33, ensuring that the first sealing plate 32 remains stable when the second sealing plate 33 moves. At the same time, the second sealing plate 33 can be operated by the operating rod 40 to ensure the correct rotation and position adjustment of the second sealing plate 33.

[0111] Specifically, the valve housing 36 is provided with a receiving cavity 37, which can accommodate the first sealing sheet 32 ​​and the second sealing sheet 33 that are stacked together. The first sealing sheet 32 ​​and the second sealing sheet 33 can be in close contact.

[0112] Alternatively, in one implementation, please combine Figure 1 The first sealing plate 32 can act as a sealing gasket. The first sealing plate 32 can be fixed at the first opening 38 and seal the valve housing 36 and the pot lid 300, thereby improving the sealing performance of the switching assembly 150 and the pot lid 300 to a certain extent. When the vent hole 34 is open, the cooking chamber 250 is connected to the outside through the vent hole 34 and the second opening 39.

[0113] Optionally, the switching assembly 150 includes a sealing gasket fixed to the first opening 38. The switching assembly 150 is sealed to the pot lid 300 via the sealing gasket. The sealing gasket has a corresponding through hole that connects to the vent hole and the cooking cavity 250. When the vent hole 34 is open, the cooking cavity 250 communicates with the outside through the through hole, the vent hole 34, and the second opening 39. The sealing gasket may be located below the first sealing plate 32, abutting against the surface of the first sealing plate 32 facing the cooking cavity 250.

[0114] In some implementations, please refer to Figures 1 to 4 The first connector 20 is provided with a first receiving groove 43, and the detection component 11 is disposed in the first receiving groove 43.

[0115] In the above embodiments, the first receiving groove 43 can fix the position of the detection element 11 and prevent it from moving or shaking within the first connecting member 20 to a certain extent, thereby ensuring the accuracy of the detection component to a certain extent and avoiding false detection or functional failure caused by changes in the position of the detection element 11.

[0116] Specifically, the first connector 20 is provided with a first receiving groove 43 for receiving the detection element 11, and the first connector 20 is connected to the second sealing sheet 33, thereby realizing the connection between the detection element 11 and the second sealing sheet 33.

[0117] In this embodiment of the utility model, when the first operating member 41 drives the first connecting member 20 to rotate, it can simultaneously drive the detection member 11 and the second sealing plate 33 to rotate, thereby realizing the switching of the cooking appliance 500 between the pressure cooking mode and the pressureless cooking mode and the position detection.

[0118] In some implementations, please refer to Figure 1 and Figure 18 The lid assembly is rotatably connected to the pot body 200. The lid assembly includes an opening component 50, an elastic component 22, and an opening button 51. The pot body 200 is provided with a locking component 52. The opening button 51 and the locking component 52 engage with each other to cover the cooking cavity 250 with the lid 300. The opening component 50 and the linkage slider 13 are connected through the elastic component 22. When the rotational force of the first operating component 41 is less than the force of the elastic component 22, the linkage slider 13 and the opening component 50 rotate together to unlock the lid 300 from the pot body 200. When the rotational force of the first operating component 41 is greater than the force of the elastic component 22, the linkage slider 13 and the opening component 50 rotate relative to each other to trigger the opening button 51 to separate from the locking component 52, thereby opening the cooking cavity 250 with the lid assembly.

[0119] In the above embodiments, when the lid 300 is locked to the pot body 200, the lid 300 can be unlocked from the pot body 200 and the cooking cavity 250 can be opened by adjusting the magnitude of the rotational force.

[0120] Specifically, the cooking appliance 500 has a lid-opening mode, which allows the lid assembly to rotate relative to the pot body 200 to open the cooking cavity 250. When the cooking cavity 250 is opened, the opening of the cooking cavity 250 is exposed to facilitate the user in taking out or placing food. Typically, the lid-opening mode is a continuation of the twist-opening mode.

[0121] The cooking appliance 500 includes a lid-opening torsion spring that connects the lid 300 and the pot body 200. A lid-opening button 51 engages with a locking piece 52 to cover the cooking cavity 250. At this time, the lid-opening torsion spring is compressed. When the lid-opening button 51 disengages from the locking piece 52, the lid-opening torsion spring drives the lid assembly to rotate relative to the pot body 200, thereby opening the cooking cavity 250.

[0122] In this embodiment of the invention, the cover-opening member 50 includes a limiting post 47, the connecting slider 13 includes a second limiting hole 49 corresponding to the limiting post 47, and the first operating member 41 includes a first limiting hole 48 corresponding to the limiting post 47. An elastic member 22 connects the cover-opening member 50 and the connecting slider 13 respectively, and the limiting post 47 passes through the second limiting hole 49 and the first limiting hole 48 in sequence. The limiting post 47 can be in a tight fit with the first limiting hole 48 and in a clearance fit with the second limiting hole 49. When the rotational force of the first operating member 41 is greater than the force of the elastic member 22, the limiting post 47 can move along the second limiting hole 49, thereby causing the connecting slider 13 to rotate relative to the cover-opening member 50. For example, the elastic member 22 can be a torsion spring.

[0123] The lid-opening button 51 is rotatably mounted on the pot lid 300. Specifically, please refer to... Figure 1 and Figure 18 The lid opening button 51 includes a pivot 53, a resilient part 54, and a hook 55. The pot lid assembly may include a top cover, which is disposed on the mounting cover 30 to cover the components on the mounting cover 30. The lid opening button 51 is rotatably connected to the top cover via the pivot 53. The mounting cover 30 has a through hole, through which the hook 55 passes and extends from the bottom surface of the mounting cover 30. When the pot lid assembly covers the cooking cavity 250, the hook 55 can engage with the locking member 52. When the lid opening member 50 abuts against the resilient part 54, the resilient part 54 can drive the hook 55 to rotate, causing the hook 55 to separate from the locking member 52, thereby opening the cooking cavity 250.

[0124] In this embodiment of the utility model, please refer to Figure 2 The cooking appliance 500 is in pressurized cooking mode and closed mode. The lid 300 is locked to the pot body 200. The lid opening button 51 and the locking piece 52 engage to cover the cooking cavity 250 with the lid 300. The magnetic switch 12 detects the detection piece 11 to determine that the second sealing piece 33 is in the first position. The first operating piece 41 is in... Figure 2 When rotating counterclockwise with a force less than that of the elastic element 22, the second sealing plate 33 can rotate clockwise, and the connecting slider 13 and the lid-opening component 50 can rotate counterclockwise together. The second sealing plate 33 can open the vent 34. The first operating component 41 can drive the lid-opening component 50 to rotate through the first limiting hole 48 and the limiting post 47. The lid-opening component 50 drives the elastic element 22 to rotate, and the elastic element 22 drives the connecting slider 13 to rotate. After the first operating component 41 rotates a certain angle, the cooking appliance 500 is in the pressure-free cooking mode and the open mode. The lid 300 is unlocked from the pot body 200, and the lid 300 covers the cooking cavity 250. The magnetic switch 12 detects the detection component 11 to determine that the second sealing plate 33 is in the second position. Figure 3 As shown. In Figure 3 When the rotational force of the first operating member 41 increases counterclockwise and exceeds the force of the elastic member 22, this rotational force can overcome the force of the elastic member 22, causing the cover opening member 50 to rotate relative to the linkage slider 13 towards the cover opening button 51. When the cover opening member 50 abuts against the elastic part 54, the elastic part 54 can drive the hook 55 to rotate, causing the hook 55 to separate from the member 52 (e.g., Figure 4 (As shown). At this time, since the hook 55 has separated from the locking part, the lid assembly is allowed to rotate relative to the pot body 200 to open the cooking cavity 250, and the cooking utensil 500 is in the open lid mode. Figure 4 In the middle, the pot lid assembly can open the cooking cavity 250 under the action of the elastic element 22.

[0125] In one embodiment, the rotation of the first operating member 41 can be achieved electrically. Specifically, the cooking appliance 500 includes a motor, which can be connected to the first operating member 41 via a transmission assembly to drive the first operating member 41 to rotate clockwise or counterclockwise. In one embodiment, the rotation of the first operating member 41 can be achieved manually. Specifically, the lid assembly includes a top cover disposed on the mounting cover 30 to cover components on the mounting cover 30, and the first operating member 41 can be exposed on or outside the top cover to allow the user to operate the first operating member 41 to rotate clockwise or counterclockwise.

[0126] In some implementations, please refer to Figures 5 to 8 The lid assembly is detachably mounted on the pot body 200. The lid assembly includes a second operating member 42. A part of the detection component is mounted on the pot body 200. The second operating member 42 is rotatably mounted on the switching component 150 and connected to the second sealing plate 33. When the second operating member 42 rotates, it drives the second sealing plate 33 to rotate relative to the first sealing plate 32.

[0127] In the above embodiments, by rotating the second operating member 42, the second sealing plate 33 can be rotated simultaneously, so that the second sealing plate 33 can switch between the first position and the second position, thereby realizing the conversion between pressurized and pressureless cooking modes.

[0128] Specifically, in this embodiment of the invention, the detection component includes a magnetic switch 12, which is disposed on the pot body 200. Optionally, the lid assembly of the cooking utensil 500 in this embodiment of the invention can be completely detached from the pot body 200.

[0129] Optionally, the switching assembly 150 includes a second connector 23 and an operating lever 40. The second connector 23 is connected to the operating lever 40, the operating lever 40 is connected to the second sealing plate 33, and the second operating member 42 is connected to the second connector 23, thereby enabling the second operating member 42 to connect to the second sealing plate 33. Optionally, the connection between the second connector 23 and the operating lever 40, between the operating lever 40 and the second sealing plate 33, and between the second operating member 42 and the second connector 23 can be a fixed connection or a detachable connection, such as an adhesive connection or a slot connection. Optionally, the connection between the two is a connection that does not involve relative rotation.

[0130] In this embodiment of the utility model, the second operating member 42 rotates, causing the second sealing plate 33 to rotate, thereby switching the second sealing plate 33 between a first position and a second position, and thus switching the cooking appliance 500 between a pressure cooking mode and a pressureless cooking mode.

[0131] The pressurized cooking mode can refer to the second sealing plate 33 closing the vent hole 34 on the first sealing plate 32 to seal the cooking chamber 250. The unpressurized cooking mode can refer to the second sealing plate 33 opening all the vent holes 34 on the first sealing plate 32 to allow the cooking chamber 250 to communicate with the outside through the vent holes 34.

[0132] In some implementations, please refer to Figures 5 to 8 The switching component 150 includes a second connector 23 and a transmission component 24. The second operating component 42 drives the second sealing plate 33 to rotate through the second connector 23 and drives the transmission component 24 to rotate through the second connector 23. The detection component 11 is disposed on the transmission component 24.

[0133] In the above embodiments, the transmission member 24 can transmit the rotational motion of the second operating member 42 to the detection member 11, so that the motion of the detection member 11 is consistent with the motion of the second sealing plate 33, thereby ensuring to a certain extent that the position of the second sealing plate 33 can be detected and fed back.

[0134] Specifically, the second operating member 42 is connected to the second connecting member 23, which is connected to both the second sealing plate 33 and the transmission member 24. The second operating member 42, through the second connecting member 23, drives the second sealing plate 33 to rotate, allowing the cooking appliance 500 to switch between pressurized and non-pressurized cooking modes. Simultaneously, it drives the transmission member 24 to rotate, causing the detection member 11 to move along with the second sealing plate 33. Optionally, the connection between the second operating member 42 and the second connecting member 23, and between the second connecting member 23 and the second sealing plate 33, can be a fixed connection or a detachable connection, such as an adhesive connection or a slot connection. Optionally, the connection between the two is one where relative rotation does not occur.

[0135] In some implementations, please refer to Figure 5 The second connecting member 23 is provided with a third tooth 18, and the transmission member 24 is provided with a fourth tooth 19. The third tooth 18 and the fourth tooth 19 mesh.

[0136] In the above embodiment, through the meshing of the teeth, the rotation of the second connecting member 23 can be accurately transmitted to the transmission member 24, thereby driving the detection member 11, so that the movement of the detection member 11 and the second sealing plate 33 is synchronized, thereby determining the sealing state of the cooking cavity 250, which is beneficial for the cooking appliance 500 to work in the correct cooking mode.

[0137] Specifically, the second connecting member 23 is connected to the transmission member 24 through the third tooth 18 and the fourth tooth 19. The rotation of the second operating member 42 drives the second connecting member 23 to rotate. The third tooth 18 of the second connecting member 23 interacts with the fourth tooth 19 of the transmission member 24, thereby driving the transmission member 24 to rotate.

[0138] In some implementations, please refer to Figures 5 to 8 The transmission component 24 is provided with a second receiving groove 44, and the detection component 11 is provided in the second receiving groove 44.

[0139] In the above embodiments, the second receiving groove 44 can fix the position of the detection element 11 and prevent it from moving or shaking in the transmission element 24 to a certain extent, thereby ensuring the accuracy of the detection component to a certain extent and avoiding false detection or functional failure caused by changes in the position of the detection element 11.

[0140] Specifically, the transmission component 24 is provided with a second receiving groove 44 for accommodating the detection component 11, and the second connecting component 23 is connected to the second sealing plate 33 via the operating rod 40.

[0141] In this embodiment of the utility model, when the second operating member 42 drives the transmission member 24 to rotate, it can simultaneously drive the second sealing plate 33 to rotate, thereby keeping the transmission member 24 containing the detection member 11 and the second sealing plate 33 moving synchronously, realizing the switching of the cooking appliance 500 between the pressure cooking mode and the pressureless cooking mode and position detection.

[0142] In some implementations, please refer to Figure 5 The transmission component 24 includes a detection part 25, which extends toward the pot body 200 and is provided with a second receiving groove 44.

[0143] In the above embodiments, the detection unit 25 can effectively drive the detection element 11 to move, ensuring the normal operation of the detection assembly.

[0144] Specifically, a magnetic switch 12 is provided on the pot body 200, the detection element 11 includes a magnet, and the detection part 25 is provided with a second receiving groove 44 near the pot body 200. The magnet is located in the second receiving groove 44 on the detection part 25 of the transmission element 24.

[0145] In some implementations, please refer to Figures 5 to 8 The transmission component 24 includes an identification part 26 located on one side of the detection part 25. The identification part 26 includes a first identification position 27 and a second identification position 28 connected to each other. The detection component includes a detection switch 29 located on the pot body 200. During the rotation of the transmission component 24, the first identification position 27 can trigger the detection switch 29 to output a first signal, and the second identification position 28 can trigger the detection switch 29 to output a second signal. The first signal and the second signal indicate that the cooking appliance 500 is in different modes.

[0146] In the above embodiments, the position of the transmission member 24 is determined by detecting the switch 29, the first identification position 27, and the second identification position 28, thereby determining different modes of the cooking appliance 500.

[0147] Specifically, the detection switch 29 includes a spring and a switch post. Normally, the spring keeps the switch post in an extended state. When the identification part 26 on the transmission member 24 rotates to a certain position, either the first identification position 27 or the second identification position 28 contacts the switch post, compressing the spring and causing the switch post to retract. One of the first identification position 27 and the second identification position 28 is a protrusion, and the other is a recess. The protrusion abuts against the switch post, causing it to retract and compressing the spring. The recess allows the spring to return to its original shape, allowing the switch post to extend.

[0148] In this embodiment of the invention, the first identification position 27 is located between the two second identification positions 28. The first identification position 27 is a protrusion; when the transmission member 24 rotates, the first identification position 27 abuts against the switch post, causing the switch post to retract. The switch post compresses the spring, thereby triggering the detection switch 29 to output a first signal. The first signal indicates that the cooking appliance 500 is in an intermediate state (i.e., between a pressureless cooking mode and a pressure cooking mode). The second identification positions 28 are recessed portions; the second identification positions 28 allow the spring to return to its original shape, driving the switch post to extend, thereby triggering the detection switch 29 to output a second signal. Figure 6 In the middle, the second signal indicates that the cooking appliance 500 is in pressurized cooking mode. Figure 7 In the middle, the second signal indicates that the cooking appliance 500 is in pressureless cooking mode. Figures 6 to 8 In the above, the first signal is the on signal of the detection switch 29, and the second signal is the off signal of the detection switch 29.

[0149] In some implementations, please refer to Figures 5 to 8 The two second identification bits 28 are located on both sides of the first identification bit 27;

[0150] When the second sealing plate 33 is in the second position or the first position, the second identification bit 28 triggers the detection switch 29.

[0151] When the second sealing plate 33 is in the position between the second position and the first position, the first identification bit 27 triggers the detection switch 29.

[0152] In the above embodiment, the first identification position 27 is located between the two second identification positions 28, corresponding to the intermediate state of the cooking appliance 500 between the closed mode and the open mode, thereby enabling the detection of the intermediate state of the cooking appliance 500 between the pressurized cooking mode and the unpressurized cooking mode.

[0153] Specifically, as shown in Table 1:

[0154]

[0155] Table 1

[0156] In Table 1, a checkmark (√) for magnetic switch 12 indicates that magnetic switch 12 has detected a magnet and is conducting; an × indicates that magnetic switch 12 has not detected a magnet and is disengaged. A checkmark (√) for detection switch 29 indicates that the switch pin of detection switch 29 is pressed (in the retracted state) and is conducting; an × indicates that the switch pin is not pressed (in the extended state) and is disengaged.

[0157] Combination Figures 5 to 8 As shown in Table 1, in one implementation method, such as Figure 6 As shown, the first identification position 27 is a convex part, and the second identification position 28 is a concave part. When the second sealing plate 33 is in the first position, the magnetic switch 12 is turned on, and the second identification position 28 located to the right of the first identification position 27 triggers the detection switch 29. The switch post is in the extended state, and the detection switch 29 outputs a second signal, and the cooking appliance 500 is in the pressurized cooking mode.

[0158] In one implementation, such as Figure 7 As shown, the first identification position 27 is a convex part, and the second identification position 28 is a concave part. When the second sealing plate 33 is in the second position, the magnetic switch 12 is disconnected, and the second identification position 28 located to the left of the first identification position 27 triggers the detection switch 29. The switch post is in the extended state, and the detection switch 29 outputs a second signal, and the cooking appliance 500 is in the pressureless cooking mode.

[0159] In one implementation, such as Figure 8 As shown, the first identification position 27 is a convex part, and the second identification position 28 is a concave part. When the second sealing plate 33 is in the position between the second position and the first position, the magnetic switch 12 is turned off, the first identification position 27 triggers the detection switch 29, the switch column is in the retracted state, the detection switch 29 outputs the first signal, and the cooking appliance 500 is in the intermediate state between the pressureless cooking mode and the pressure cooking mode.

[0160] In this embodiment of the utility model, since the cooking appliance 500 may be in a pressureless cooking mode or an intermediate state when the magnetic switch 12 is off, the detection switch 29 can further determine whether the cooking appliance 500 is in a pressureless cooking mode or an intermediate state.

[0161] Optionally, the cooking appliance 500 includes a heating element and a controller. The heating element heats the cooking chamber 250 when turned on, and the controller is electrically connected to the heating element and the detection element. When the magnetic switch 12 is on and the detection switch 29 is off, the heating element is turned on to put the cooking appliance 500 into a pressurized cooking mode. When the magnetic switch 12 is off and the detection switch 29 is on, the heating element can be turned on or off according to user selection or program settings to put the cooking appliance 500 into a pressureless cooking mode. When the magnetic switch 12 is off and the detection switch 29 is on, the controller turns the heating element off. When the magnetic switch 12 is on and the detection switch 29 is on, the controller turns the heating element off.

[0163] In some implementations, please refer to Figure 5 The pot lid assembly includes an inner lid 31, which is connected to the pot lid 300, and a transmission component 24 is rotatably mounted on the inner lid 31.

[0164] In the above embodiments, the transmission component 24 is rotatably mounted on the inner cover 31, which allows the transmission component 24 to move and rotate flexibly within a limited range.

[0165] Specifically, the transmission component 24 is provided with a strip groove, and correspondingly, the inner cover 31 is provided with a screw hole. The screw passes through the strip groove and connects with the screw hole, thereby connecting the transmission component 24 and the inner cover 31. The screw can move within the strip groove, thereby enabling the transmission component 24 to be rotatably mounted on the inner cover 31.

[0166] Optionally, the inner lid 31 and the pot lid 300 are rotatably connected.

[0167] In some implementations, please refer to Figures 9 to 11The switching assembly 150 includes a valve housing 36 and an operating lever 40. The valve housing 36 has a receiving cavity 37. A first sealing plate 32 and a second sealing plate 33 are disposed in the receiving cavity 37. The receiving cavity 37 has a first opening 38 and a second opening 39 at its two ends, respectively. The first opening 38 faces the cooking cavity 250, and the second opening 39 faces away from the cooking cavity 250. The operating lever 40 is connected to the second sealing plate 33 and the second connecting member 23. The second connecting member 23 drives the second sealing plate 33 to rotate through the operating lever 40.

[0168] In the above embodiments, a robust receiving cavity 37 can be provided by the valve housing 36 to accommodate the first sealing plate 32 and the second sealing plate 33, ensuring that the first sealing plate 32 remains stable when the second sealing plate 33 moves. At the same time, the second sealing plate 33 can be operated by the operating rod 40 to ensure the correct rotation and position adjustment of the second sealing plate 33.

[0169] Specifically, the valve housing 36 is provided with a receiving cavity 37, which can accommodate the first sealing sheet 32 ​​and the second sealing sheet 33 that are stacked together.

[0170] Optionally, the switching assembly 150 includes a sealing gasket disposed at the first opening 38. The switching assembly 150 is sealed to the pot lid 300 through the sealing gasket. When the vent 34 is open, the cooking chamber 250 communicates with the outside through the vent 34 and the second opening 39. The sealing gasket is located below the first sealing plate 32 and abuts against the surface of the first sealing plate 32 facing the cooking chamber 250.

[0171] In some implementations, please refer to Figure 11 One of the second sealing plate 33 and the operating rod 40 is provided with a slot 45, and the other is provided with a block 46. The block 46 is located in the slot 45 so that when the operating rod 40 rotates, the second sealing plate 33 is driven to rotate through the cooperation of the block 46 and the slot 45.

[0172] In the above embodiments, the locking block 46 can cooperate with the locking slot 45 so that when the operating lever 40 moves, it can drive the second sealing plate 33 to make planar movement on the first sealing plate 32.

[0173] Specifically, in one embodiment, the slot 45 is disposed on the surface of the second sealing sheet 33 facing away from the cooking cavity 250, and the block 46 is disposed on the surface of the operating lever 40 facing the cooking cavity 250. In another embodiment, the slot 45 may be disposed on the surface of the operating lever 40 facing the cooking cavity 250, and the block 46 may be disposed on the surface of the second sealing sheet 33 facing away from the cooking cavity 250.

[0174] The locking block 46 can be locked into the locking slot 45, so that the operating rod 40 and the second sealing plate 33 are tightly fitted. When the operating rod 40 moves, it can drive the second sealing plate 33 to make planar movement on the first sealing plate 32.

[0175] This embodiment of the invention does not specifically limit the number of card slots 45 and card blocks 46. In one example, there are two card slots 45 and two card blocks 46. One card block 46 is disposed in one corresponding card slot 45.

[0176] In some implementations, please refer to Figure 11 The second sealing plate 33 has a notch 35. When the notch 35 is connected to the vent hole 34 in the vertical direction, the second sealing plate 33 opens the vent hole 34. When the notch 35 is not connected to the vent hole 34 in the vertical direction, the second sealing plate 33 closes the vent hole 34.

[0177] In the above embodiment, the cooperation between the notch 35 and the vent hole 34 allows adjustment of the opening area of ​​the vent hole 34 to regulate the connectivity between the cooking cavity 250 and the outside environment. This enables the pressure cooking appliance 500 to flexibly adjust the internal pressure of the cooking cavity 250 according to different cooking needs. The venting area of ​​the vent hole 34 can refer to the opening area of ​​the vent hole 34, while the opening area refers to the area used for venting steam when the vent hole 34 is opened. The opening area can be greater than 0% of the venting area and less than or equal to 100% of the venting area.

[0178] Specifically, notch 35 is located on the side of the second sealing plate 33. When notch 35 is connected to vent 34 in the vertical direction, switching component 150 opens vent 34, connecting the cooking chamber 250 to the outside, allowing steam to be released; when notch 35 is not connected to vent 34 in the vertical direction, switching component 150 closes vent 34, preventing the cooking chamber 250 from connecting to the outside and maintaining a sealed state, preventing steam from escaping from the cooking chamber 250 to the outside. This invention does not specifically limit the number of notches 35; in one example, there are two notches 35, with one notch 35 corresponding to one vent 34.

[0179] Optionally, the area of ​​the notch 35 is not less than the steam vent area of ​​the vent 34, so that the vent 34 can be fully opened when the cooking appliance 500 is selected for pressureless cooking. The size of the notch 35 can be specifically limited according to actual needs, and this utility model does not make a specific limitation in this regard.

[0180] Understandably, please combine Figure 3 The second sealing piece 33 is in the second position, and when the first operating member 41 is rotated further counterclockwise to put the cooking appliance 500 into the open mode (such as...). Figure 4When the first connecting piece 20 is rotated clockwise by a certain angle, the second sealing piece 33 rotates clockwise by a certain angle under the action of the first connecting piece 20. Since the area of ​​the notch 35 is larger than the venting area of ​​the vent hole 34, it provides a certain margin for the second sealing piece 33 to rotate by a certain angle. Therefore, the vent hole 34 can still be fully opened at this time.

[0181] In some embodiments, the switching component 150 is detachably mounted on the pot lid 300.

[0182] In the above embodiments, the switching component 150 can be stably installed on the pot lid 300 to ensure normal operation when the cooking appliance 500 is cooking. At the same time, the switching component 150 can be disassembled to facilitate the cleaning of the switching component 150 and the cooking appliance 500.

[0183] Specifically, a fixing part is provided above the pot lid assembly, and the switching assembly 150 is detachably connected to the fixing part. Optionally, the switching assembly 150 and the fixing part can be connected together by a detachable connection method such as bolts, pins, clips, or threads, making the switching assembly 150 easy to maintain and replace parts.

[0184] In this embodiment of the invention, the switching component 150 is detachably connected to the fixing part. The connection method between the switching component 150 and the fixing part can be specifically defined according to actual needs.

[0185] The present invention does not specifically limit the manufacturing process of the fixing part. In one example, the fixing part may be manufactured by means of thread fixing, riveting fixing, welding fixing or integral casting with the pot lid 300.
