Description

Technical Field

[0001] This utility model relates to the field of electric pressure cooker technology, and in particular to an electric pressure cooker with an automatic exhaust structure. Background Technology

[0002] Electric pressure cookers typically have a vent and a vent valve on the lid. This vent valve usually has a pressure limiting block; the weight of the pressure limiting block forces the vent valve down to seal the vent. During cooking, when the pressure inside the pot becomes too high, the internal pressure pushes open the vent valve, intermittently releasing pressure to stabilize the internal pressure. After pressure cooking is complete, the vent valve often needs to be manually rotated or moved to release the internal pressure. The lid can only be opened after a certain period. This manual venting mechanism, if not released before opening the lid, poses a safety hazard, especially for older adults.

[0003] To provide a better customer experience, existing technologies include electric pressure cooker exhaust valves. For example, Chinese Patent No. 202223047878.5 discloses a cooking appliance comprising: a pot body, including an outer shell and a middle plate located at the upper end of the outer shell; a lid, closable and fitted onto the pot body, the lid including a cover, an exhaust pipe, and a pressure-limiting valve, the exhaust pipe passing through the cover and the pressure-limiting valve located at the upper end of the exhaust pipe; a pressure relief assembly, including a solenoid valve and an exhaust rod, the solenoid valve being driven connected to one end of the exhaust rod, and the other end of the exhaust rod being driven connected to the pressure-limiting valve; and a support located inside the outer shell. This existing technology controls the opening of the pressure relief assembly through a solenoid valve, using the solenoid valve to push the exhaust. However, because the lid floats a considerable distance after the electric pressure cooker is pressurized, the overall volume of the pot body is also large, resulting in a bulky structure, high cost, and low product competitiveness. Therefore, further improvements are needed. Utility Model Content

[0022] Example Reference Figure 1 and Figure 2 The present invention proposes an electric pressure cooker with an automatic exhaust structure, comprising a pot body 10 and a pot lid 20 detachably installed on the pot body 10; the pot lid 20 is provided with an exhaust valve assembly 30 and an exhaust drive assembly 40. The pot lid 20 is provided with a vent hole 21; the vent valve assembly 30 is movably mounted in the vent hole 21; the vent drive assembly 40 includes a drive push rod 41 and a drive motor 42; the output end of the drive motor 42 is provided with a rotating block 43; the drive push rod 41 is movably mounted in the pot lid 20, located below the vent hole 21; a drive push block 411 is provided on one side of the drive push rod 41, and the drive push block 411 is located close to the rotating block 43; when the drive motor 42 rotates the rotating block 43, it can push the drive push block 411 and make the drive push rod 41 move upward, thereby pushing the vent valve assembly 30 upward.

[0023] This invention employs a simplified motor drive structure. This structure uses a small drive motor 42 as its core, paired with a sophisticated rotating lever 43, to precisely convert the motion of the drive components into the up-and-down linear motion of the drive push rod 41. This design fully utilizes the limited space of the lid 20, integrating all automatic venting mechanisms within the lid 20 without occupying external or internal space of the lower pot body 10. This effectively avoids the problem of bulky structure and increased size of the pot body 10 caused by traditional electric venting solutions. It enables one-button automatic venting, with the control center performing timed automatic venting after cooking. This completely eliminates the safety hazards of manual operation while simplifying the overall structure and reducing manufacturing costs. The product maintains a compact appearance and good versatility while possessing higher safety and intelligence levels, significantly enhancing its market competitiveness.

[0024] In this embodiment, the pot lid 20 is provided with a drive mounting base 22; the drive mounting base 22 has a vertically extending channel structure, and the drive push rod 41 is slidably mounted on the drive mounting base 22. The drive mounting base 22 with its vertical channel structure provides a stable and space-saving guiding foundation for the drive push rod 41, ensuring the accuracy of its linear movement and making the layout of the entire drive assembly within the pot lid 20 more reasonable.

[0025] Furthermore, the drive push rod 41 is provided with a guide block 412; the drive mounting base 22 is provided with a guide groove 221, and the guide block 412 is slidably mounted in the guide groove 221. The cooperation between the guide block 412 and the guide groove 221 further enhances the stability of the drive push rod 41 in a compact space, prevents it from twisting or jamming when pushed, and improves the reliability of the action.

[0026] In this embodiment, a guide hole 211 is provided below the exhaust hole 21; a guide push post 413 is provided at the top of the drive push rod 41, and the guide push post 413 passes through the guide hole 211 and is located below the exhaust valve assembly 30. The arrangement of the guide push post 413 and the guide hole 211 ensures the guiding effect within a limited space, and the pushing force of the drive push rod 41 can be accurately and centrally transmitted to the exhaust valve assembly 30, avoiding the dispersion of force and structural interference.

[0027] In this embodiment, the pot lid 20 is provided with a bypass pressure relief hole 23 and a floating valve 50. The floating valve 50 can float up and down within the bypass pressure relief hole 23, and a plug 51 is provided at its lower part. When the inside of the pot body 10 is under high pressure, the plug 51 and the floating valve 50 can be moved upward to block the bypass pressure relief hole 23. When the pressure inside the pot body 10 decreases and approaches atmospheric pressure, the floating valve 50 and the plug 51 fall down and open the bypass pressure relief hole 23. The bypass pressure relief hole 23 and the floating valve 50 constitute a passive safety system independent of the main exhaust valve. Its structure is compact and can be integrated into the pot lid 20 without occupying additional space, realizing automatic pressure management and safety redundancy.

[0028] Specifically, the floating valve 50 is equipped with a magnetic part 52, and the pot lid 20 is equipped with a Hall effect sensor 60. When the floating valve 50 and the plug 51 fall, the magnetic part 52 approaches the Hall effect sensor 60. By using the compact Hall effect sensor 60 in conjunction with the magnetic part 52 on the floating valve 50, a silent and non-contact detection of the internal pressure state of the pot lid 20 is achieved, providing a key signal for intelligent system control. The control center can determine whether the internal pressure of the pot body 10 is within a safe value based on this Hall effect signal.

[0029] In some embodiments, the lid 20 and the pot body 10 are separate units; the electronic components of the lid 20 and the pot body 10 are electrically connected through coupling plug terminals. The design of the coupling plug terminals allows the lid 20, which integrates an automatic venting assembly, to be quickly electrically connected and disconnected from the pot body 10, maintaining the convenience of the separate structure and facilitating cleaning and maintenance.

[0030] In some embodiments, the lid 20 and the pot body 10 are separate components; the electronic components of the lid 20 and the pot body 10 are wirelessly powered via a wireless power supply assembly. This fundamentally avoids the risks of poor contact, power outages, or sparking caused by contact oxidation, contamination, or wear, greatly improving the long-term reliability and safety of the product. Secondly, it makes the lid 20 a completely electrically isolated component, allowing users to clean it freely without worrying about water damage to the circuitry, greatly enhancing the ease of use and user experience. Finally, wireless power supply lays a solid foundation for the complete wireless integration of the lid 20 and the pot body 10, allowing for greater freedom in structural design.

[0031] Furthermore, the electronic components of the lid 20 and the pot body 10 transmit control signals via an infrared signal module. The control commands from the mainboard of the pot body 10 to the actuators such as the automatic exhaust component on the lid 20, as well as the signals fed back from the sensors on the lid 20 (such as the Hall effect sensor 60), can all be exchanged wirelessly in a stable and rapid manner. Complementing the wireless power supply component, this constitutes a complete wireless solution of "wireless energy transmission and wireless signal communication," ultimately achieving a connection between the lid 20 and the pot body 10 without any physical cables or electrical contacts. This not only simplifies the mechanical structure and reduces the failure rate but also provides users with a seamless and convenient user experience.

[0032] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
