Description

Technical Field

[0002] As a kitchen appliance integrating the functions of a pressure cooker and a rice cooker, the electric pressure cooker is deeply loved by consumers for its fast, efficient and multi-functional features. However, in existing electric pressure cooker products, the realization of the automatic steam exhaust function generally depends on complex mechanical structures, such as the combined use of components like springs, levers and pistons. These traditional designs not only increase the manufacturing cost of the products, but also have many problems in practical applications. For example, due to the complex structure, the reliability is poor and faults are likely to occur. Especially after long-term use, the mechanical parts are frequently worn, deformed or blocked, seriously affecting the steam exhaust efficiency and the service life of the equipment.

[0003] In addition, the traditional automatic steam exhaust system is often integrated inside the cooker body and is not easy to disassemble and clean. This not only increases the difficulty of cleaning, but also makes it difficult to remove the residual food particles and grease, becoming a breeding ground for bacteria and posing a potential threat to food hygiene. Moreover, in order to ensure the stable operation of the steam exhaust system, precision-machined metal parts and complex assembly processes are often used in the prior art, which undoubtedly raises the production cost of the products and weakens the market competitiveness of the products.

[0004] In addition, although some high-end electric pressure cookers on the market are equipped with advanced cooking modes and intelligent control systems, due to the complexity of the steam exhaust mechanism, the user operation interface is cumbersome, and it is difficult for ordinary users to get started quickly, reducing the user-friendliness of the products.

[0039] As a kitchen appliance integrating the functions of a pressure cooker and a rice cooker, the electric pressure cooker is deeply loved by consumers for its fast, efficient and multi-functional features. However, in existing electric pressure cooker products, the realization of the automatic exhaust function generally relies on complex mechanical structures, such as the combined use of components like springs, levers and pistons. These traditional designs not only increase the manufacturing cost of the product, but also have many problems in practical applications. For example, due to the complex structure, the reliability is poor and it is prone to failures. Especially after long-term use, the mechanical parts are frequently worn, deformed or blocked, seriously affecting the exhaust efficiency and the service life of the equipment.

[0040] In addition, the traditional automatic exhaust system is often integrated inside the cooker body and is not easy to disassemble and clean. This not only increases the difficulty of cleaning, but also makes it difficult to remove the remaining food particles and grease, becoming a breeding ground for bacteria and posing a potential threat to food hygiene. Moreover, in order to ensure the stable operation of the exhaust system, precision-machined metal parts and complex assembly processes are often used in the prior art, which undoubtedly raises the production cost of the product and weakens the market competitiveness of the product.

[0041] In addition, although some high-end electric pressure cookers on the market are equipped with advanced cooking modes and intelligent control systems, due to the complexity of the exhaust mechanism, the user operation interface is cumbersome, and it is difficult for ordinary users to get started quickly, reducing the user-friendliness of the product.

[0042] Therefore, there is an urgent need in the current market for a new type of automatic exhaust solution, which should be able to simplify the exhaust structure, improve the reliability and durability of the system, reduce the production cost, and at the same time facilitate the user to clean and maintain, so as to meet the higher demands of modern families for healthy, safe and convenient cooking.

[0043] For this purpose, as Figures 1 to 4As shown in the figure, an electric pressure cooker with automatic steam exhaust proposed by the present utility model includes a cooker body assembly 100, a lid assembly 200 detachably connected to the cooker body assembly 100, and a steam path assembly 330 installed on the lid assembly 200. Among them, the steam path structure includes a first conductive member 310 installed on the cooker body assembly 100, a second conductive member 320 installed on the lid assembly 200, and a steam path assembly 330 installed on the lid assembly 200. Specifically, the steam path assembly 330 includes an electromagnetic drive member 331, an exhaust pipe 332, and a magnetic member. The lower end of the exhaust pipe 332 is communicated with the interior of the cooker body assembly 100, and the electromagnetic drive member 331 is electrically connected to the second conductive member 320. In application, when the second conductive member 320 is disconnected from the first conductive member 310, the electromagnetic drive member 331 and the magnetic member are magnetically attracted to drive the magnetic member to block the upper end of the exhaust pipe 332. In addition, when the lid assembly 200 and the second conductive member 320 move together and drive the second conductive member 320 to conduct with the first conductive member 310, the electromagnetic drive member 331 forms a magnetic force and drives the magnetic member to separate from the exhaust pipe 332 to exhaust steam to the outside of the lid assembly 200. It should be noted that when the lid assembly 200 and the cooker body assembly 100 are in different mating connection positions, through the magnetic force cooperation of the electromagnetic drive member 331 and the magnetic member, the switching between pressure sealing and automatic steam exhaust is realized, without a complex mechanical mechanism, greatly simplifying the steam exhaust mechanism and reducing the failure rate; in addition, the electromagnetic drive member 331 can be energized according to the signal of the circuit board to form a magnetic force, and can be extended to an intelligent steam exhaust function, improving the cooking efficiency and safety. In some embodiments, the lid assembly is swingably connected to the cooker body assembly, and reference can be made to the structure of a flip-top rice cooker (not shown in the figure). In some embodiments of the present utility model, the lid assembly 200 can be detachably arranged on the cooker body assembly 100, which greatly facilitates the cleaning and maintenance work of users. It is not only beneficial to disassemble, maintain or clean the steam path assembly 330 such as the electromagnetic drive member 331, the exhaust pipe 332 and the magnetic member, but also can conveniently clean the inner side of the lid assembly 200, avoiding the accumulation of food residues and water scale, and ensuring the hygienic conditions of cooking.

[0044] Refer again to Figures 1 to 3, the pot body assembly 100 is rotatably connected to the lid body assembly 200, making the opening and closing of the lid body assembly 200 easier and more natural. At the same time, it also ensures the tight fit of the lid body assembly 200 with the pot body assembly 100 in the closed state, improving the safety and pressure control accuracy during the cooking process. Specifically, the pot body assembly 100 includes a pot body 110, and the lid body assembly 200 includes a pot lid body 210. The pot body 110 is provided with an alignment groove 1101, and the alignment groove 1101 is arc-shaped. The pot lid body 210 is provided with an arc-shaped alignment protrusion 211, and the alignment protrusion 211 is arranged corresponding to the position of the alignment groove 1101. The central angle corresponding to the alignment groove 1101 is greater than the central angle corresponding to the alignment protrusion 211. This ensures the precise alignment of the pot lid body 210 and the pot body 110, improving the operation efficiency and the user experience. For example, the central angle corresponding to the alignment groove 1101 is 60°. Compared with the situation where the pot lid body can rotate 360° relative to the pot body, the alignment protrusion 211 provides a mark for the user to use the pot lid body 210, enabling the pot lid body 210 to directly align with the alignment groove 1101. After insertion, the pot lid body 210 can be rotated, so that the rotation amplitude required for the pot lid body 210 after alignment insertion is small, and the automatic steam exhaust function after rotation and locking can be achieved. Therefore, the user can use it more conveniently, improving the user experience. Further, the first conductive member 310 is placed in the alignment groove 1101, and the second conductive member 320 is adapted to be inserted into the alignment groove 1101 and rotate in the alignment groove 1101, ensuring that even during the rotation and closing process of the pot lid body 210, the connection effect between the first conductive member 310 and the second conductive member 320 is ensured, realizing a stable electrical connection.

[0045] In some applications, when the lid body assembly 200 is rotated and locked in place, the second conductive member 320 is electrically connected to the first conductive member 310 to form a reliable connection, enabling the electromagnetic drive component 331 to be conducted with the power source provided on the pot body assembly 100 through the first conductive member 310. Among them, the electromagnetic drive component 331 includes an electromagnetic coil and an iron core (not shown in the figure). It should be noted that when an iron core made of a magnetic material is placed in the electromagnetic coil, the iron core is magnetized and generates magnetism. In addition, for an electromagnet, when the excitation coil is energized, a magnetic flux is generated and forms a closed magnetic circuit through the iron core and the armature, causing the armature to be magnetized and generating a different-sex magnetic force from the iron core. In some embodiments of the present invention, the magnetic member is a magnetic valve cap 333, and a magnet 3331 is provided inside the magnetic valve cap 333. Generally, the iron core and the magnet 3331 are magnetically attracted. When the electromagnetic coil is energized, a magnetic field is generated around the electromagnetic coil to repel the magnet 3331 and drive the magnetic valve cap 333 to separate from the steam hole 3321 at the upper end of the exhaust pipe 332. Specifically, a blocking block 3332 is also provided inside the magnetic valve cap 333. The blocking block 3332 is suspended above the steam hole 3321 and is adapted to move downward under the drive of the magnetic valve cap 333 to block the upper end of the steam hole 3321.

[0046] In some embodiments of the present utility model, one of the first conductive member 310 and the second conductive member 320 is an elastic contact, and the other is a fixed contact piece. The elastic contact is in contact and conduction with the fixed contact piece, ensuring the stability and reliability of the electrical connection even during the frequent opening and closing of the cover body assembly 200. Moreover, the elastic recovery ability of the elastic contact helps to reduce the wear between the contacts and extend the service life of the electrical connection assembly. Compared with the connection between contacts, the reliability of the cooperation connection between the contact and the contact piece is higher. Specifically, referring to Figures 1 to 3 , the first conductive member 310 is an elastic contact, and the elastic contact is elastically installed with the pot body assembly 100 through a compression spring 311. The second conductive member 320 is a fixed contact piece, and a guiding surface 3201 is provided on the side of the fixed contact piece facing the elastic contact to gradually press down the elastic contact. The design of the guiding surface 3201 can not only ensure that the fixed contact piece smoothly presses down the elastic contact when the cover body assembly 200 is closed to realize a reliable connection of the circuit, but also scrape off foreign matters on the surface of the contact during the contact process between the contact piece and the contact, keep the contact clean, and avoid poor contact caused by foreign matters. Optionally, the guiding surface 3201 is an inclined surface or an arc surface. Further, there are two first conductive members 310 and two second conductive members 320. The pot body assembly 100 includes a partition 120. The two first conductive members 310 are respectively arranged on both sides of the partition 120, and the second conductive members 320 correspond to the first conductive members 310 one by one. For example, the first conductor is connected to the positive pole of the external power supply of the pot body 110, and the second conductor is connected to the negative pole of the external power supply of the pot body 110. Moreover, the setting of the partition 120 can effectively separate the first conductive member 310 and the second conductive member 320 to avoid short circuit caused by the contact between the first conductive member 310 and the second conductive member 320.

[0047] In some embodiments of the present utility model, as Figure 1 shown, the cover body assembly 200 includes a steam-permeable shield 220. The steam-permeable shield 220 is arranged inside the cover body assembly 200, and the lower end of the exhaust pipe 332 is placed inside the steam-permeable shield 220, protecting the exhaust pipe 332 from external factors, such as preventing foreign matters from entering or accidental collision, ensuring the smoothness of the exhaust process, reducing the possibility of steam leakage, and improving the use safety and efficiency of the equipment.

[0048] The above has described the embodiments of the present utility model in detail with reference to the drawings. However, the present utility model is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present utility model within the knowledge scope of those of ordinary skill in the art.
