[0024] Optionally, when the fastener is in the unlocked position, the projection of the upper fastening portion along the height direction at least partially overlaps with the projection of the inner lining along the height direction.

[0025] Optionally, when the fastener is in the unlocked position, the width of the overlapping portion of the projection of the upper fastening part along the height direction and the projection of the inner lining along the height direction is greater than or equal to 1 mm.

[0026] According to this solution, the upper fastening part will not detach from the mounting part when the fastening part is retracted to the outermost position.

[0027] Optionally, the cover is provided with limiting portions, which are located on both sides of the fastener in the width direction;

[0028] When the fastener is in the locked position, at least a portion of the projection of the limiting portion coincides with the projection of the fastener on the plane where the centerline of the fastener and the height direction are located.

[0029] According to this solution, the fastener can maintain the correct posture when it is in the locked position, preventing it from coming off or deflecting.

[0030] Optionally, the fasteners are evenly distributed along the circumference of the cover; and / or

[0031] The number of fasteners is 2-6.

[0077] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0078] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0079] This invention provides a cooking appliance. The cooking appliance of this invention can function as a rice cooker, electric pressure cooker, electric slow cooker, electric hot pot, and soy milk maker. The cooking appliance is suitable for pressure cooking.

[0080] The following will combine Figures 1 to 14 A detailed description of the cooking utensil according to this utility model is provided.

[0081] like Figures 1 to 2 , Figures 4 to 5 , Figures 10 to 11 As shown, the cooking appliance of this utility model includes a lid 200 and a pot body 100. The pot body 100 is used for cooking food, and the lid 200 is used to cover the pot body 100. For example, the lid 200 is connected to the pot body 100 in an openable and closable manner to cover the pot body 100. When the lid 200 covers the pot body 100, a cooking space is formed between the lid 200 and the pot body 100. Optionally, when the lid 200 covers the pot body 100, the lid 200 is sealed to the inner pot 110.

[0082] The pot body 100 is typically a rounded rectangular parallelepiped shape and has a cylindrical inner pot storage section. The pot body 100 includes an inner pot 110, which can be freely inserted into or removed from the inner pot storage section for easy cleaning. The inner pot 110 is typically made of metal and is used to hold materials to be heated, such as rice or soup. The pot body 100 also includes a middle plate 120 and a base 130. The middle plate 120 is located at the top of the pot body 100, and the base 130 is located on the sides and bottom of the pot body 100. The middle plate 120 is fixedly mounted to the base 130.

[0083] To reduce heat loss during cooking, the pot body 100 also includes a heat insulation cover 140 disposed on the outer periphery of the inner pot 110. The heat insulation cover 140 is fitted onto the outer periphery of the inner pot 110 and is located between the inner pot 110 and the base 130.

[0084] The cover 200 includes a top cover, a liner 210, and a removable cover 220. The top cover is located on the outermost side of the cover 200, forming the outer shell of the cover 200. The liner 210 is located below the top cover and is connected to it. For example, the liner 210 can be connected to the top cover by fasteners or snaps. The top cover and the liner 210 constitute the upper cover assembly. The upper cover assembly is mainly used to centrally mount various functional components of the cover 200 that sense and control the working status of the cooking appliance, such as sensors. The removable cover 220 is located on the innermost side of the cover 200 and is located below the liner 210. The removable cover 220 is detachably connected to the liner 210, for example, by snaps, for easy cleaning and replacement. The removable cover 220 is oriented towards the cooking space, that is, when the cover 200 is in the closed position, the removable cover 220 is directly above the cooking space.

[0085] In this design, the fastener 300 can engage with the edge of the inner pot 110 or the edge of the insulation cover 140. For example, in a rice cooker, the fastener 300 can engage with the edge of the inner pot 110. For example, in an electric pressure cooker, the edge of the insulation cover 140 is at least partially exposed, and the fastener 300 can engage with the edge of the insulation cover 140. For ease of explanation, the following description focuses on the fastener 300 engaging with the edge 111 of the inner pot 110.

[0086] The cooking appliance also includes a locking assembly. The locking assembly includes a fastener 300, a rotating frame 400, and a drive component. Optionally, the rotating frame 400 is rotated by the drive component. The drive component can be, but is not limited to, a drive motor. The output shaft of the drive motor can be connected to the rotating frame 400 via a transmission component to drive the rotating frame 400 to rotate. The fastener 300 is connected to the rotating frame 400. The main function of the fastener 300 is to achieve locking and unlocking between the lid 200 and the pot body 100 through its movement.

[0087] Optionally, the rotating frame 400 and the drive component are positioned above the cover 210. The fastening component 300 is positioned below the cover 210. The fastening component 300 is connected to the rotating frame 400 and the cover 210 respectively via a connector 340.

[0088] The rotating frame 400 is provided with a transmission hole 401 corresponding to the connector 340, and the cover 210 has a connecting groove 2101 extending along its thickness direction. The connector 340 is slidably connected to the transmission hole 401 and slidably connected to the connecting groove 2101. When the rotating frame 400 rotates, the connector 340 moves within the transmission hole 401 and is guided by the connecting groove 2101, so that the fastener 300 moves radially between a locked position and an unlocked position. The engagement of the transmission hole 401 and the connecting groove 2101 converts the rotational motion of the rotating frame 400 into the linear motion of the fastener 300.

[0089] The rotating frame 400 allows multiple fastening elements 300 to operate simultaneously. Optionally, the fastening elements 300 can move along a straight line perpendicular to the central axis of the lid 200 to lock or unlock the edge 111 of the inner pot 110, providing a simple and flexible locking and unlocking method. Understandably, the direction of movement of the fastening elements 300 may intersect or be opposite to the central axis of the lid 200. In this design, the fastening elements 300 can move radially along the removable lid 220, meaning their direction of movement intersects with the central axis of the removable lid 220. During cooking, when it is necessary to lock the lid 200 and the pot body 100, the drive unit activates, generating a driving force. This force is transmitted to the fastening elements 300 via the rotating frame 400, causing them to move towards the center of the pot body 100. When the fastening elements 300 reach the appropriate position, they securely lock the lid 200 and the pot body 100 together. Optionally, when the fastening member 300 is in the locked position, it can engage with the edge 111 of the inner pot 110. When the lid 200 needs to be opened, the drive unit drives the rotating frame 400 to move in the opposite direction, causing the fastening member 300 to move away from the center of the pot body 100. When the fastening member 300 moves to the appropriate position, it disengages from the pot body 100, allowing the lid 200 to open, and the fastening member 300 is in the unlocked position. In this design, the radial direction of the removable lid 220 is the same as the radial direction of the inner pot 110. The movement of the fastening member 300 along the radial direction of the inner pot 110 ensures that the fastening member 300 can apply pressure evenly during engagement, enhancing the stability between the lid 200 and the pot body 100.

[0090] In some embodiments of the present utility model, the fastening members 300 are evenly distributed along the circumferential direction of the cover body 200. The number of the fastening members 300 is 2 - 6. Optionally, the number of the fastening members 300 can be 2, 3, 4, 5, or 6, and preferably 4. The fastening members 300 are evenly distributed along the circumferential direction of the cover body 200. Through reasonable quantity and angle arrangements, the space at the edge of the cover body 200 can be utilized maximally, so that both the fastening members 300 and the fixing members can meet the functional requirements without looking crowded, ensuring that the cover body 200 receives uniform pressure and support when closed, thereby improving the stability.

[0091] The lining cover 210 is provided with a connecting groove 2101 penetrating along its thickness direction. The connecting groove 2101 is in the same direction as the moving direction of the fastening member 300. The connecting member 340 extends from below the lining cover 210 to above the lining cover 210 via the connecting groove 2101, so that the fastening member 300 is hung on the lining cover 210 and moves along the connecting groove 2101 under the drive of the rotating frame 400. The hanging connection method greatly simplifies the assembly structure between the fastening member and the lining cover 210. While achieving a movable connection, the connecting member 340 can serve as a transmission structure to transmit the driving force of the driving member to the fastening member 300.

[0092] In some embodiments of the present utility model, the fastening member 300 includes an upper fastening portion 310, a lower fastening portion 330, and an intermediate portion 320. The upper fastening portion 310 and the lower fastening portion 330 are respectively connected to the upper and lower ends of the intermediate portion 320, and both the upper fastening portion 310 and the lower fastening portion 330 extend towards the center line direction of the cooking appliance. The fastening member 300 forms a structure similar to a "匚" shape, so as to be able to form a certain clamping space. The fastening member 300 is fastened to the pot inner liner 110 through the clamping space, making the cover body 200 and the pot inner liner 110 closely connected. In the state where the fastening member 300 is in the fastening position, the upper fastening portion 310 can generate a downward pulling force on the cover body 200, and the lower fastening portion can generate an upward pulling force on the cooker body 100, thereby improving the stability of the connection between the cover body 200 and the cooker body 100 and ensuring good sealing performance during pressure cooking. Optionally, the upper fastening portion 310 is movably connected to the lining cover 210, and the lower fastening portion 330 can be selectively connected to or disengaged from the pot inner liner 110 to switch between the locking position and the unlocking position.

[0093] In this solution, in the state where the fastening member 300 is in the locking position, the projection of the lower fastening portion 330 along the height direction of the cooking appliance at least partially coincides with the projection of the edge 111 of the pot inner liner 110 along the height direction. The fastening member 300 can be tightly fastened on the edge 111 of the pot inner liner 110 to form an effective seal. This seal not only helps to prevent steam leakage during cooking, but also keeps the temperature and pressure inside the cooking appliance stable, thereby improving the cooking effect.

[0094] In this design, when the fastener 300 is in the unlocked position, the lower fastener 330 is offset from the inner pot 110, and the projection of the lower fastener 330 along the height direction is spaced apart from the projection of the edge 111 of the inner pot 110 along the height direction. When the user needs to open the cooking appliance, the fastener 300 can be easily moved to the unlocked position.

[0095] During cooking, the fastener 300 floats up and down as the pressure inside the cooking space changes. For example, when pressure is applied to the cooking space, the pressure acts on the lid 200, causing the lid 200 to float upwards.

[0096] In this design, a seal is achieved by fastening the inner pot 110 with the fastener 300 and the edge 111. During cooking, the edge 111 of the inner pot 110 may be subjected to an upward pulling force from the lower fastener 330. After prolonged use, the edge 111 may deform, with an upward convexity and a downward concaveness. If the unfastening travel is insufficient, the deformed edge may still be locked with the fastener 300 when the fastener 300 is in the unlocked position, making it impossible to open the lid.

[0097] Reference Figure 5 In this design, when the fastener 300 is in the unlocked position, the distance d1 between the projection of the lower fastening part 330 along the height direction and the projection of the edge 111 of the inner pot 110 along the height direction is 5-9mm. That is, the release amount d1 of the fastener 300 is 5-9mm. Optionally, the release amount d1 can be, but is not limited to, 5mm, 6mm, 7mm, 8mm, 9mm, etc. In this design, considering the dimensional tolerance of the inner pot 110 opening (±0.5), the dimensional tolerance of the fastener 300 (±0.3), and the single-offset of the inner pot 110 (±2mm), this release amount ensures that when the fastener 300 is unlocked, the deformed edge of the pot will not jam or obstruct the lower fastening part 330, thus ensuring that the user can easily and smoothly open the cooking appliance. This spacing takes into account the possible convex and concave deformation of the edge 111 of the inner pot 110 during long-term use. Even if the edge 111 of the inner pot 110 deforms, the 5-9mm release allowance ensures that the fastener 300 effectively avoids the deformed edge 111 of the inner pot 110.

[0098] As shown above, during the cooking process, the edge 111 of the inner pot 110 may deform. If the fastening gap between the fastening part 300 and the edge 111 of the inner pot 110 is too small, the fastening part 300 may easily come off, posing a risk of frying.

[0099] Reference Figure 11In some embodiments of this utility model, when the fastening member 300 is in the locked position, the width d2 of the overlapping portion of the projection of the lower fastening part 330 along the height direction and the projection of the inner pot 110 along the height direction is 5-7mm. That is, the fastening amount d2 between the fastening member 300 and the inner pot 110 is 5-7mm. Optionally, the disengagement amount d2 can be, but is not limited to, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, etc. In this solution, considering the dimensional tolerance of the inner pot 110 opening ±0.5mm, the dimensional tolerance of the fastening member 300 ±0.3mm, and the influence of assembly tolerances, the fastening amount is defined as 5-7mm. This fastening amount can ensure that the lower fastening part 330 and the edge 111 of the inner pot 110 are tightly fitted, forming an effective seal, preventing steam leakage during cooking, and maintaining stable temperature and pressure inside the cooking appliance. Considering the slight deformation that may occur on the edge 111 of the inner pot 110 during long-term use, a 5-7mm fastening allowance is provided to allow for some space. Even if the edge 111 of the inner pot 110 has slight deformation, it can still ensure effective contact between the lower fastening part 330 and the edge 111 of the inner pot 110 without affecting the sealing performance.

[0100] Reference Figure 5 In some embodiments of this utility model, the height difference d3 between the lower edge of the edge 111 of the inner pot 110 and the upper edge of the lower fastening part 330 is greater than or equal to 0.5mm. Optionally, the height difference d3 can be, but is not limited to, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, etc. This height difference setting prevents the edge 111 of the inner pot 110 from interfering with the fastening part 300 during the movement of the fastening part 300 in the locked and unlocked positions, ensuring smooth movement of the fastening part 300, thereby further ensuring that the fastening part 300 can be accurately aligned when it moves to the locked position.

[0101] In some embodiments of this utility model, the fastening member 300 is located between the cover 200 and the middle plate 120. Due to the limited internal space of the cooking appliance and the compact installation of the components, interference may occur between the fastening member 300 and the middle plate 120 during movement. Figure 1 As shown, in this invention, a clearance groove 121 is provided on the upper surface of the middle plate 120. The clearance groove 121 provides sufficient movement space for the fastener 300 without increasing the overall size, ensuring that it is not obstructed during movement. This makes the operation of the cooking appliance smoother and more reliable, improving the user experience.

[0102] Reference Figure 5 and Figure 11In this invention, when the lid 200 is closed onto the pot body 100, at least a portion of the lower latching portion 330's orthogonal projection onto the middle plate 120 falls into the clearance groove 121. Optionally, the orthogonal projection of the lower latching portion 330 in both the locked and unlocked positions falls into the clearance groove 121. That is, during the process of the lid 200 moving from the unlocked position to the locked position and from the locked position to the unlocked position, the lower latching portion 330 is always aligned with the clearance groove 121, thus preventing any interference between the latching member 300 and the middle plate 120 in different states of the latching member 300.

[0103] In some embodiments of this utility model, a recessed area can be designed in the middle plate 120 to form a relief groove 121. That is, the upper surface of the middle plate 120 is recessed inward along the thickness direction to form the relief groove 121. This structure makes the forming method of the relief groove 121 simple and direct.

[0104] Optionally, an additional component with a groove can be installed on the middle plate 120. This groove matches the movement trajectory of the lower latching part 330 and serves as a clearance groove 121, thereby providing clearance space when the lower latching part 330 moves. The position and shape of the clearance groove 121 can be adjusted as needed.

[0105] Reference Figure 5 In some embodiments of this utility model, the height difference d4 between the lower edge of the lower engaging portion 330 and the bottom of the clearance groove 121 is greater than or equal to 0.5 mm. Optionally, the height difference d4 can be, but is not limited to, 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, etc. This height difference setting prevents the fastener 300 from interfering with the pot plate 120 along its side during the movement of the fastener 300 in the locked and unlocked positions, ensuring smooth movement of the fastener 300, thereby further ensuring that the fastener 300 can move smoothly to the locked or unlocked position.

[0106] In some embodiments of this utility model, the cover 210 further includes a mounting portion 212. The mounting portion 212 is used to mount the removable cover 220. The mounting portion 212 is disposed in the middle of the cover 210. The mounting portion 212 is provided with a mounting groove 2121. Optionally, the mounting portion 212 and the body portion of the cover 210 are spaced apart to form the mounting groove 2121. The end of the upper fastening portion 310 away from the middle portion 320 is located in the mounting groove 2121. That is, the upper fastening portion 310 extends into the gap between the mounting portion 212 and the body portion of the cover 210. The mounting groove 2121, without affecting the installation of the removable cover 220, can also accommodate the end of the upper fastening portion 310, thereby achieving support for the fastening member 300 and guiding its movement.

[0107] In some embodiments of this utility model, at least the projection of the bottom wall of the mounting groove 2121 along the height direction coincides with the projection of the upper fastening part 310 in the unlocked position along the height direction, such as... Figure 14 As shown, the width d5 ​​of the overlapping portion is greater than or equal to 1 mm. Optionally, the width d5 ​​can be, but is not limited to, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc. Understandably, the overlapping portion of the projection of the fastening member 300 in the locked position and the projection of the bottom wall of the mounting groove 2121 is larger than the overlapping portion of the projection of the fastening member 300 in the unlocked position and the projection of the bottom wall of the mounting groove 2121. In this embodiment, the width of the overlapping projection of the upper fastening part 310 in the unlocked position and the bottom wall of the mounting groove 2121 is greater than or equal to 1 mm, which can ensure effective support of the upper fastening part 310 by the mounting part 212. This prevents the upper fastening part 310 from disengaging from the mounting part 212 when the fastening member 300 is retracted to its outermost position.

[0108] In some embodiments of this utility model, the cover 200 is provided with a limiting portion 211. Specifically, the liner 210 has a first surface facing the pot body 100, and the first surface is provided with the limiting portion 211. Optionally, the limiting portion 211 is located on both sides of the fastening member 300 in the width direction.

[0109] In some embodiments of this utility model, when the fastener 300 is in the locked position, at least a portion of the projection of the limiting portion 211 coincides with the projection of the fastener 300 on the plane where the centerline and height direction of the fastener 300 are located. The limiting portion 211 ensures that the fastener 300 maintains the correct posture in the locked position, preventing deflection and allowing the fastener 300 to move smoothly along a predetermined path during unlocking, reducing the risk of jamming and damage, and ensuring a stable snap-fit ​​connection between the fastener 300 and the edge 111 of the pot liner 110. Optionally, the limiting portion 211 is located on both sides of the fastener 300 along its width direction.
