[0001] This utility model relates to a cooking utensil. Background Technology

[0002] Existing cooking appliances use locking mechanisms to ensure a tight seal between the lid and the inner pot. These locking mechanisms are typically movably connected to the lid via connectors. However, due to the limited internal space of the cooking appliance, this can cause interference with the inner pot during movement.

[0003] Therefore, there is a need to provide a cooking appliance that can at least partially solve the above problems. Utility Model Content

[0004] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, this utility model provides a cooking utensil, comprising:

[0006] The pot body includes a fastening edge, a shell, and a middle plate disposed at the upper end of the shell. The fastening edge is located above the middle plate, and the upper surface of the middle plate is provided with a clearance groove.

[0007] A lid, which is closable and disposed at the upper end of the pot body; and

[0008] A fastening element is movably disposed on the cover body along a straight line direction perpendicular to the central axis of the cover body. The fastening element includes a lower fastening portion adapted to engage with the fastening edge. In the projection of a plane parallel to the height direction of the cooking appliance, the lower fastening portion can be located between the fastening edge and the middle plate.

[0009] Wherein, the extending direction of the clearance groove corresponds to the moving path of the fastener, and / or the number of clearance grooves corresponds to the number of fasteners;

[0010] When the lid is closed onto the pot body, the fastening member can extend into the relief groove, and at least part of the movement path of the lower fastening part is located within the relief groove along the axial direction of the lid.

[0011] According to this utility model, the cooking appliance, through the setting of the clearance groove, provides sufficient movement space for the fasteners without increasing the overall size, ensuring that they are not obstructed during movement. This prevents the middle plate from interfering with the movement of the fasteners under abnormal conditions. By setting the extension direction of the clearance groove to the movement direction of the fasteners, and / or by matching the number of clearance grooves to the number of fasteners, the layout or function of other components inside the cooking appliance is avoided.

[0012] Optionally, one end of the clearance groove near the center of the cooking appliance protrudes upward from the bottom of the groove to form a water-blocking part.

[0013] According to this solution, by setting up a water-blocking part, water droplets are confined within the avoidance groove, thereby preventing water droplets from intruding into the interior of the pot.

[0014] Optionally, the water-retaining portion is lower than the upper surface of the middle plate.

[0015] According to this solution, the water-blocking part can achieve the function of blocking water while avoiding interference with the movement of the fastening parts to a certain extent.

[0016] Optionally, the depth of the portion of the clearance groove near the center of the cooking appliance is less than the depth of the portion of the clearance groove away from the center of the cooking appliance; and / or

[0017] The upper surface of the portion of the clearance groove near the center of the cooking appliance is lower than the upper surface of the middle plate.

[0018] According to this design, the portion of the clearance groove closest to the center of the cooking appliance is made shallower, causing condensation droplets to tend to accumulate in the deeper part of the groove. The upper surface of the inclined clearance groove is lower than the middle plate, which to some extent avoids interference with the movement of the fasteners.

[0019] Optionally, the height difference between the highest point of the portion of the clearance groove near the center of the cooking appliance and the lowest point of the bottom of the clearance groove is greater than or equal to 1 mm.

[0020] According to this solution, the height difference limits the clearance groove to have a certain water accumulation capacity, so as to prevent water droplets from entering the inside of the pot body, while not affecting the movement of the fastener.

[0021] Optionally, the upper surface of the middle plate is recessed inward along the thickness direction to form the clearance groove.

[0022] According to this scheme, this structure makes the forming method of the clearance groove simple and direct.

[0023] Optionally, the depth of the clearance groove is greater than 1.5 mm.

[0024] According to this solution, it is ensured that the fastener will not collide or rub against the bottom of the clearance groove when it moves between the fastening position and the unlocking position, or when it floats up or falls down.

[0025] Optionally, the fasteners are evenly distributed along the circumference of the cover;

[0026] The clearance grooves are evenly distributed along the circumference of the cover.

[0027] According to this scheme, the circumferentially evenly distributed arrangement ensures a more uniform distribution of contact pressure between the lid and the edge of the pot when the lid is closed.

[0028] Optionally, the number of fasteners is 2-6;

[0029] The number of clearance slots is 2-6.

[0030] According to this solution, by setting this number, it can be ensured that the contact pressure distribution between the lid and the edge of the pot body is more uniform when the lid is closed.

[0031] Optionally, the width of the clearance groove is greater than the width of the lower fastening portion.

[0032] According to this design, the lower latch can easily extend into the clearance groove.

[0033] Optionally, the fastener has a locked position and an unlocked position, and the fastener in the locked position can extend into the clearance groove;

[0034] When the fastener is in the locked position, a movable gap is formed between the lower fastening part and the inner wall of the clearance groove, and the gap on one side is greater than or equal to 0.5mm along the width direction of the lower fastening part.

[0035] According to this solution, sufficient movement space is provided for the lower latching part by setting the activity gap.

[0036] Optionally, the fastener has a locked position and an unlocked position, and the fastener in the locked position can extend into the clearance groove;

[0037] When the fastener is in the locked position, the distance between the fastener and the middle plate is greater than or equal to 0.5 mm.

[0038] According to this solution, sufficient movement space is provided for the fasteners to ensure smooth operation during locking and unlocking.

[0039] Optionally, the fastening component further includes an upper fastening portion and a middle portion, wherein the upper fastening portion and the lower fastening portion are respectively connected to the upper and lower ends of the middle portion, and both the upper fastening portion and the lower fastening portion extend toward the center line of the cooking appliance;

[0040] When the fastener is in the locked position, the cover and the fastening edge are located between the upper fastening portion and the lower fastening portion.

[0041] According to this solution, the upper and lower fastening parts are designed to provide clamping in both upward and downward directions for the lid and the pot body, which improves the stability of the connection and ensures good sealing performance during pressure cooking.

[0042] Optionally, the pot body includes a pot inner and a heat-insulating cover, and the fastening edge is formed on the pot inner or the heat-insulating cover; wherein,

[0043] The fastening element is movable in the radial direction of the inner pot.

[0044] According to this solution, different cooking needs can be met by adjusting the fastening of the fasteners with different fastening edges. When the fasteners are fastened to the inner pot or the heat preservation cover, they move radially along the inner pot, thereby ensuring that the fasteners can apply pressure evenly during fastening and enhancing the stability between the lid and the pot body.

[0084] 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.

[0085] 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.

[0086] The following will combine Figures 1 to 13 A detailed description of the cooking utensil according to this utility model is provided.

[0087] like Figure 1 , Figures 8 to 13 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] In this design, the fastener 300 can engage with the edge 111 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 111 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.

[0092] Optionally, 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 rotates via 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.

[0093] 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.

[0094] 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.

[0095] 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 fastening member 300 moves radially along the removable lid 220 or radially along the inner pot 110, thereby ensuring that the fastening member 300 applies pressure evenly during engagement, enhancing the stability between the lid 200 and the pot body 100. In this design, the radial direction of the removable lid 220 is the same as the radial direction of the inner pot 110.

[0096] 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 via a connector 340.

[0097] The connecting groove 2101 moves in the same direction as the fastener 300. The connecting member 340 extends from below the cover 210 to above the cover 210 via the connecting groove 2101, so that the fastener 300 is suspended from the cover 210 and moves along the connecting groove 2101 under the drive of the rotating frame 400. The suspended connection method greatly simplifies the assembly structure between the fastener 300 and the cover 210. While achieving a movable connection, the connecting member 340 can also serve as a transmission structure to transmit the driving force of the driving member to the fastener 300.

[0098] 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.

[0099] Reference Figures 5 to 7 , 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 respectively extend from the upper and lower ends of the intermediate portion 320 to one side thereof. The fastening member 300 forms a structure similar to a "C" shape, so as to be able to form a certain clamping space. The fastening member 300 is fastened to the inner pot 110 through the clamping space, so that the cover body 200 and the inner pot 110 are tightly 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 330 can generate an upward pulling force on the cooking body 100, thereby improving the stability of the connection between the cover body 200 and the cooking 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 inner pot 110 to switch between the locking position and the unlocking position.

[0100] In the projection on a plane parallel to the height direction of the cooking appliance, the lower fastening portion 330 is lower than the edge 111 of the inner pot 110 and higher than the middle plate 120. The lower fastening portion 330 in the locking position is located between the edge 111 of the inner pot 110 and the middle plate 120. In the limited space, the setting of the relative position of the lower fastening portion 330 can maximize the use of space and improve the convenience of use.

[0101] As can be seen from the above, the fastening member 300 is located between the cover body 200 and the middle plate 120. Due to the limited internal space of the cooking appliance, the components are compactly installed. In some unexpected situations, such as deformation of the middle plate 120, manufacturing tolerances, and improper installation of the fastening member 300, interference may occur between the fastening member 300 and the middle plate 120 during the movement of the fastening member 300. Refer to Figures 2 to 4 , in the present utility model, an avoidance groove 121 is provided on the upper surface of the middle plate 120. Through the setting of the avoidance groove 121, sufficient moving space can be provided for the fastening member 300 without increasing the overall size. The fastening member 300 can extend into the avoidance groove 121 to ensure that it will not be hindered during the movement process. Prevent the interference of the middle plate 120 on the movement of the fastening member 300 in abnormal situations. Make the operation of the cooking appliance smoother and more reliable, and improve the user experience. In the state where the cover body 200 is covered on the cooking body 100, in the projection along the axial direction of the cover body 200, at least part of the movement path of the lower fastening portion 320 is located in the avoidance groove 121.

[0102] Refer to Figure 8 And Figure 9In 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 within the clearance groove 121. Optionally, the orthogonal projection of the lower latching portion 330 in both the locked and unlocked positions falls within 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 avoiding 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] During cooking, especially in methods that require water such as steaming, boiling, or stewing, a large amount of steam is generated in the cooking space. This steam may condense into water droplets, which flow along the edges of the lid 200 and the inner pot 110 to the upper surface of the middle plate 120. The aforementioned clearance groove 121 is generally lower than the surface of the middle plate 120. Water droplets can easily flow into the clearance groove 121, and may even flow into the interior of the pot body 100, causing damage to the appliance.

[0106] In some embodiments of this utility model, the depth d4 of the clearance groove 121 is greater than 1.5 mm. Optionally, the depth d4 can be, but is not limited to, 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, 2.5 mm, etc. This ensures that the fastening member 300 does not collide or rub against the bottom of the clearance groove 121 when moving between the fastening position and the unlocking position, or when floating up or down, thereby ensuring the smooth movement of the fastening member 300 and the sealing of the cover 200.

[0107] Reference Figure 9 In some embodiments of this invention, the end of the relief groove 121 near the inner pot 110 protrudes upward from the bottom of the groove to form a water-blocking part 122. The water-blocking part 122 forms an effective barrier. When steam condenses into water droplets and flows into the relief groove 121, the water-blocking part 122 prevents these droplets from continuing to flow forward, ensuring they are confined within the relief groove 121, thereby preventing water droplets from intruding into the interior of the pot body 100.

[0108] Optionally, the water-blocking part 122 is lower than the upper surface of the middle plate 120. While realizing the water-blocking function, the water-blocking part 122 also avoids interference with the movement of the fastener 300 to a certain extent.

[0109] Optionally, the fastening member 300 in the locked position is positioned above the water-blocking portion 122. Optionally, the fastening member 300 in the locked position is offset from the water-blocking portion 122. In either case, the water-blocking portion 122 can, to a certain extent, avoid interference with the fastening member 300.

[0110] Reference Figure 11 In some embodiments of this utility model, the depth of the portion of the relief groove 121 near the inner pot 110 is less than the depth of the portion of the relief groove 121 away from the inner pot 110. That is, the portion of the relief groove 121 near the inner pot 110 is made shallower, and condensate droplets in the relief groove 121 tend to accumulate in the deeper portion of the relief groove 121.

[0111] Optionally, the upper surface of the portion of the clearance groove 121 near the center of the cooking appliance is lower than the upper surface of the center plate. This arrangement, to a certain extent, avoids interference of the clearance groove 121 with the movement of the fastener 300.

[0112] Through the above embodiments, water droplets are less likely to flow directly into the pot body 100, thereby reducing the risk of electrical short circuits and damage to a certain extent.

[0113] Based on the above embodiments, the height difference between the highest point of the portion of the relief groove 121 near the inner pot 110 and the lowest point of the bottom of the relief groove 121 is greater than or equal to 1 mm. Optionally, the height difference between the highest point of the portion of the relief groove 121 near the inner pot 110 and the lowest point of the bottom of the relief groove 121 can be, but is not limited to, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc. Optionally, the height of the water-blocking part 122 within the relief groove 121 is greater than or equal to 1 mm. Optionally, the height of the water-blocking part 122 within the relief groove 121 can be, but is not limited to, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc. By limiting this height difference, the relief groove 121 has a certain water accumulation capacity to prevent water droplets from intruding into the interior of the pot body 100, while not affecting the movement of the fastening member 300. The fastener 300 can move smoothly along the preset trajectory without interfering with the water-blocking part 122 or the end of the relief groove 121 near the pot body 100.

[0114] In some embodiments of this utility model, the fastening members 300 are evenly distributed along the circumference of the cover 200. The number of fastening members 300 is 2-6. Optionally, the number of fastening members 300 can be 2, 3, 4, 5, or 6, preferably 4. The even distribution of the fastening members 300 along the circumference of the cover 200, through a reasonable arrangement of their number and angle, can maximize the use of the space at the edge of the cover 200, so that the fastening members 300 and the fixing members can meet the functional requirements without appearing crowded, ensuring that the cover 200 is subjected to uniform pressure and support when closed, thereby improving stability.

[0115] For example, the number of fastening members 300 is set to 4. With the center of the inner pot 110 as the center, the angle between adjacent fastening members 300 is 90 degrees. As mentioned above, the pot body 100 is a rounded cuboid shape. Optionally, the angle between the fastening members 300 and the midline of the length or the midline of the width of the pot body 100 is 45 degrees.

[0116] In some embodiments of this utility model, the clearance groove 121 is correspondingly provided with the fastening member 300. The corresponding arrangement of the clearance groove 121 and the fastening member 300 provides sufficient movement space for the fastening member 300, preventing interference or collision with other parts of the pot body 100 or lid 200 during movement, thus ensuring smooth movement of the fastening member 300. The number of clearance grooves 121 corresponds to the number of fastening members 300. For example, if there are four fastening members 300, there should also be four clearance grooves 121 to ensure that each fastening member 300 has a corresponding clearance groove 121 to provide movement space and support. In this solution, the clearance groove 121, while providing clearance for the fastening member 200, ensures that the fastening member 300 moves along a preset trajectory during movement. By aligning the position and / or number of the clearance grooves 121 with the fastening members 300, the layout or function of other components inside the cooking appliance is avoided.

[0117] In some embodiments of this invention, the width d1 of the clearance groove 121 is greater than the width d2 of the lower fastening portion 330. Because the clearance groove 121 is wider than the lower fastening portion 330, the lower fastening portion 330 can easily extend into the clearance groove 121. The clearance groove 121 also provides sufficient movement space for the fastening member 300, preventing friction or collision with the edge of the clearance groove 121 during movement.

[0118] Based on the above embodiment, when the fastener 300 falls, it can fall into the clearance groove 121. A movable gap is formed between the lower fastening portion 330 of the fastener 300 and the inner wall of the clearance groove 121. Along the width direction of the lower fastening portion 330, the gap on one side is greater than or equal to 0.5 mm. Optionally, the gap on one side can be, but is not limited to, 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, etc. By setting the movable gap, sufficient movement space is provided for the lower fastening portion 330.

[0119] In actual production, due to factors such as materials and processes, the dimensions of the lower latching part 330 and the clearance groove 121 may have certain tolerances. Setting a certain clearance can accommodate these tolerances and ensure that cooking utensils manufactured in different batches or under different production conditions can maintain good fit and smooth operation.

[0120] In some embodiments of this utility model, when the fastening member 300 is in the locked position, the distance d3 between the fastening member 300 and the middle plate 120 is greater than or equal to 0.5mm. Optionally, the distance d3 can be, but is not limited to, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, etc. That is, when the fastening member 300 is fully lowered, there is still a certain distance between the lower fastening part 330 and the middle plate 120, providing sufficient movement space for the fastening member 300 to ensure smooth operation during locking and unlocking, and avoiding jamming or damage due to insufficient space.
