Description

Technical Field

[0001] This application relates to the field of cooking equipment technology, and more particularly to a lid and a cooking utensil. Background Technology

[0002] Currently, there are many types of cooking appliances, including rice cookers, pressure cookers, and slow cookers. Taking pressure cookers as an example, their application in daily life is extremely widespread. Whether it's a pressure cooker that uses an open flame or one that is electrically heated, ease of use and operability are the most important concerns for most users.

[0003] In related technologies, a pressure cooker includes a lid and a pot body. The lid fits onto the pot body and has a locking position that engages with the pot body and an unlocking position that releases the locking mechanism from the pot body. Users can switch the lid from the locking position to the unlocking position by pulling the handle.

[0004] However, when a user lifts the handle to move the pressure cooker, the lid will switch to the unlocked position and the latch will unlock, causing the lid to open and making it inconvenient for the user to move the pressure cooker. Utility Model Content

[0005] This application provides a lid and a cooking utensil, aiming to improve the problem of inconvenient handling of cooking utensils in related technologies.

[0006] To address the aforementioned technical problems, this application provides a lid that can be opened and closed onto a pot body, the pot body comprising an outer shell, an outer pot, and an inner pot, characterized in that the lid comprises: Inner cover; A lid is installed on the side of the inner lid that faces away from the pot body; The lid is rotatably connected to the inner lid and is located on the side of the inner lid facing the pot body. The lid has a locking position that engages with the outer pot and an unlocking position that unlocks with the outer pot. A transmission assembly is installed on the inner cover and is connected to the pot lid in a transmission manner. A handle is driven to the end of the transmission assembly furthest from the lid; when the handle is pulled upwards, it drives the transmission assembly to switch the lid from the locked position to the unlocked position. A limiting component is installed on the lid and has a limiting state for limiting the lid when it is in the locked position and a releasing state for releasing the lid from the locked position.

[0007] In some embodiments, when the lid is in the locked position and the limiting component is in the limiting state, the limiting component limits the transmission component, so as to limit the lid in the locked position through the transmission component.

[0008] In some embodiments, the limiting component includes: A stop plate, rotatably mounted on the cover; and A button is mounted on the faceplate and is connected to the stop plate in a driving manner; When the limiting component switches from the released state to the limiting state, the button drives the end of the stop plate component near the transmission component to move towards the transmission component, so as to be located on the rotation path of the transmission component and block the rotation of the transmission component.

[0009] In some embodiments, the limiting component further includes: A first elastic element is installed on the cover and abuts against the end of the stop plate near the transmission assembly, so that the end of the stop plate near the transmission assembly tends to move toward the transmission assembly.

One of the transmission component and the driven component is provided with a spiral groove, and the other of the transmission component and the driven component is provided with a driving part. The driving part is inserted into the spiral groove. When the transmission component switches from the locked position to the released position, the transmission component drives the driven component to rotate through the cooperation of the driving part and the spiral groove, and drives the pot lid to rotate from the locked position to the unlocked position. When the limiting component is in the limiting state, the stop plate limits the driven member.

[0011] In some embodiments, the upper cover further includes a hanging shaft connecting the driven member and the pot lid, and the pot lid is rotatably disposed below the inner cover via the hanging shaft; The driven member is connected to a fork, which extends from the driven member toward the edge of the pot lid. The fork is provided with a drive groove, and the pot lid is connected to a lever. The lever is spaced apart from the rotation axis of the pot lid and is movably inserted into the drive groove. When the limiting component is in the limiting state, the end of the stop plate near the shift fork is located on the rotation path of the shift fork to prevent the shift fork from rotating.

[0012] In some embodiments, the inner cover has a protruding limiting rib on its surface facing away from the pot body, and the limiting rib and the surface of the inner cover form a limiting groove, and the fork, the lever, and the limiting component are all located in the limiting groove.

[0013] In some embodiments, the top cover further includes: At least one elastic push rod, the elastic push rod including a second elastic element and a top block, one end of the second elastic element abutting against the surface of the inner cover facing the pot body, and the other end of the second elastic element being connected to the top block; When the top cover is placed on the pot body and not in operation, the top block and the pot cover are fitted with a clearance. When the top cover is placed on the pot body and is in operation, the top block abuts against the pot cover.

[0014] In some of these embodiments, the lid is provided with an anti-rotation part; The top cover also includes: An anti-rotation block is slidably installed on the inner cover; When the upper cover is not placed on the pot body, the anti-rotation block cooperates with the anti-rotation part to prevent the pot cover from rotating; When the top cover is placed on the pot body, the outer shell abuts against the anti-rotation block, driving the anti-rotation block to move away from the outer shell, so that the anti-rotation block disengages from the anti-rotation part.

[0015] In some embodiments, the anti-rotation block includes: The main body is slidably mounted on the inner cover; The abutment portion is disposed at one end of the main body near the outer shell; A connecting portion is disposed on the outer peripheral wall of the main body and located between the inner cover and the pot lid; and A limiting part is provided on the surface of the connecting part facing the pot lid; When the upper cover is not placed on the pot body, the limiting part cooperates with the anti-rotation part to prevent the pot cover from rotating; When the top cover is placed on the pot body, the outer shell abuts against the abutting part, driving the main body to move away from the outer shell, so that the limiting part disengages from the anti-rotation part.

[0016] In some embodiments, the top cover further includes: The first reset member abuts against the anti-rotation block, causing the anti-rotation block to tend to move closer to the outer casing.

[0017] In some embodiments, the top cover further includes; The control component is installed inside the handle and is electrically connected to the pot body.

[0018] This application also provides a cooking utensil, including: A pot body includes an outer shell, an outer pot, and an inner pot, wherein the outer pot is installed inside the outer shell, and the inner pot is disposed inside the outer pot; and The aforementioned lid is foldably mounted on the pot body and is used to seal the inner pot to form a cooking cavity.

[0019] In some embodiments, the outer peripheral wall of the lid is provided with a clearance hole, and the outer peripheral wall of the pot lid is provided with a driving protrusion. The outer peripheral wall of the outer shell is provided with a limiting protrusion, the limiting protrusion is provided with a receiving groove, and the receiving groove is provided with a limiting hole away from the groove wall of the outer pot; The top cover also includes: A pin is retractably installed on the inside of the faceplate, and one end of the pin can extend out of the faceplate through the clearance hole; When the upper cover is placed on the outer pot and the pot lid is switched from the unlocked position to the locked position, the pin is located in the receiving groove, and the driving protrusion drives the pin to move away from the pot lid. The end of the pin away from the pot lid extends into the limiting hole.

[0020] In some embodiments, the top cover further includes: The second reset element abuts against the pin, causing the pin to tend to move toward the pot lid.

[0021] In some embodiments, the top cover further includes: The mounting component is installed on the inner side of the cover and has a through hole; The pin is movably mounted on the mounting component, with one end of the pin passing through the through hole and the other end passing through the clearance hole.

[0022] In some embodiments, the pin is provided with a limiting ring portion, which abuts against the mounting member when the pot lid is in the unlocked position.

[0023] In some embodiments, the lower surface of the mounting component is provided with a positioning part, and the bottom of the receiving groove is provided with a mating part, wherein the positioning part and the mating part are inserted into each other.

[0024] In the embodiments of this application, when the user moves the cooking appliance by pulling the handle, the limiting component first operates to limit the lid in the locked position, so that the user will not switch the lid to the unlocked position when pulling the handle. This avoids the lid opening the outer pot during the lifting process, which would make it inconvenient for the user to move the cooking appliance. As a result, the lid remains in the locked position when the user pulls the handle, which makes it convenient for the user to move the cooking appliance. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] Currently, there are many types of cooking appliances, including rice cookers, pressure cookers, and slow cookers. Taking pressure cookers as an example, their application in daily life is extremely widespread. Whether it's a pressure cooker that uses an open flame or one that is electrically heated, ease of use and operability are the most important concerns for most users.

[0030] In related technologies, a pressure cooker includes a lid and a pot body. The lid fits onto the pot body and has a locking position that engages with the pot body and an unlocking position that releases the locking mechanism from the pot body. Users can switch the lid from the locking position to the unlocking position by pulling the handle.

[0031] However, when a user lifts the handle to move the pressure cooker, the lid will switch to the unlocked position and the latch will unlock, causing the lid to open and making it inconvenient for the user to move the pressure cooker.

[0032] Based on this, please refer to Figures 1 to 2 This application proposes a cover 11 and a cooking utensil 1, aiming to improve the problem of inconvenient handling of the cooking utensil 1 in the related art.

[0033] Cooking appliance 1 may include one of a pressure cooker, a rice cooker, and an electric slow cooker. This embodiment does not limit the specific type of cooking appliance 1. For ease of explanation in the following embodiments, the cooking appliance 1 in the following embodiments is a pressure cooker, and the advantages of the cooking appliance 1 of this application will be described in detail.

[0034] Taking a pressure cooker as an example, the cooking appliance 1 includes a pot body 12 and a lid 11. The pot body 12 typically includes an outer shell 121, an outer pot 122, and an inner pot 123. The inner pot 123 is used to directly hold food and is detachably installed inside the outer pot 122 for easy cleaning and replacement by the user. It also prevents the user from directly contacting the heated surface of the inner pot 123, reducing the risk of burns. The outer pot 122 can act as an insulation layer to reduce heat loss, allowing the food in the inner pot 123 to be heated more quickly and evenly. The outer shell 121 can protect the outer pot 122 and the inner pot 123.

[0035] Please see Figure 1 The upper cover 11 is foldably mounted on the pot body 12. The upper cover 11 may be separate from the pot body 12 or it may be hinged to the pot body 12; no specific limitation is made here.

[0036] Please see Figure 2 The upper cover 11 includes an inner cover 111, a top cover 112, a pot lid 113, a handle 115, and a limiting component 116. The top cover 112 is installed on the side of the inner cover 111 facing away from the pot body 12 to protect the inner cover 111. The top cover 112 can be made of a relatively hard plastic or a metal material; no specific limitation is made here. The top cover 112 can be detachably installed on the inner cover 111 or fixedly installed on the inner cover 111; no specific limitation is made here. Preferably, the top cover 112 is detachably installed on the inner cover 111, so that when the top cover 112 is scratched or damaged, it can be removed for maintenance or replacement.

[0037] Please see Figure 1 The lid 113 is rotatably connected to the inner lid 111 and is located on the side of the inner lid 111 facing the pot body 12. The lid 113 has a locking position that locks with the outer pot 122 and an unlocking position that unlocks from the outer pot 122. After the upper lid 11 covers the pot body 12, the lid 113 and the inner pot 123 seal together to form a cooking cavity 13. Usually, the lid 113 is provided with a sealing ring to seal the gap between the lid 113 and the inner pot 123, thereby improving the sealing of the cooking cavity 13 and thus improving the cooking effect of the cooking appliance 1.

[0038] There are many ways in which the lid 113 and the outer pot 122 can be locked together. For example, the lid 113 may have threads on its outer periphery, and the outer pot 122 may have threaded grooves on its inner wall. When the lid 113 is in the locked position, the lid 113 and the outer pot 122 are locked together by the engagement of the threads and the threaded grooves. When the lid 113 is in the unlocked position, the threads and the threaded grooves are spaced apart on the circumference of the lid 113. Alternatively, the lid 113 may have a latching part on its outer periphery, and the outer pot 122 may have a latching groove on its inner wall. The lid 113 and the outer pot 122 are locked together by the engagement of the latching part and the latching grooves. When the lid 113 is in the unlocked position, the latching part and the latching grooves are spaced apart on the circumference of the lid 113. These are just a few examples; a complete list is not provided here.

[0039] Please see Figure 1 The transmission component 114 is installed on the inner cover 111 and is connected to the pot lid 113. The handle 115 is driven to the end of the transmission component 114 away from the pot lid 113. When the handle 115 is pulled upward, it drives the transmission component 114 to switch the pot lid 113 from the locked position to the unlocked position.

[0040] Please see Figures 2 to 3 The limiting component 116 is installed on the lid 112 and has a limiting state for limiting the lid 113 when it is in the locked position and a releasing state for releasing the limiting of the lid 113 when it is in the locked position. It should be noted that the limiting component 116 can directly cooperate with the lid 113 to limit the lid 113, or it can indirectly limit the lid 113 by acting on the transmission component 114 to limit the limiting component 116.

[0041] Please see Figures 4 to 5 When the user needs to open the pot body 12, first switch the limit component 116 to the unlocked state, then pull the handle 115. The handle 115 drives the transmission component 114 to switch the pot lid 113 from the locked position to the unlocked position. Continue to pull the handle 115 to open the pot body 12.

[0042] Please see Figures 2 to 3 When the user needs to move the cooking appliance 1, first switch the limiting component 116 to the limiting state. The pot lid 113 is limited by the limiting component 116 and cannot rotate. The pot lid 113 remains in the locked position. At this time, the cooking appliance 1 can be moved by pulling the handle 115.

[0043] In this embodiment of the application, when the user moves the cooking appliance 1 by pulling the handle 115, the limiting component 116 first operates to limit the lid 113 in the locked position, so that the user will not switch the lid 113 to the unlocked position when pulling the handle 115. This avoids the lid 11 opening the outer pot 122 during the lifting process, which would make it inconvenient for the user to move the cooking appliance 1. As a result, the lid 113 remains in the locked position when the user pulls the handle 115, which makes it convenient for the user to move the cooking appliance 1.

[0044] Please see Figures 2 to 3 In some embodiments of this application, when the pot lid 113 is in the locked position and the limiting component 116 is in the limited state, the limiting component 116 limits the transmission component 114, thereby limiting the pot lid 113 in the locked position through the transmission component 114. With this configuration, the limiting component 116 and the transmission component 114 cooperate to limit the pot lid 113, thereby reducing the contact between the limiting component 116 and the pot lid 113 and reducing wear on the pot lid 113.

[0045] Please see Figure 3 as well as Figure 5 In some embodiments of this application, the limiting component 116 includes a stop plate 1161 and a button 1162. The stop plate 1161 is rotatably mounted on the face cover 112, and the button 1162 is mounted on the face cover 112 and is convexly connected to the stop plate 1161. When the limiting component 116 switches from the released state to the limiting state, the button 1162 drives the end of the stop plate 1161 component near the transmission component 114 to move towards the transmission component 114, so as to be located on the rotation path of the transmission component 114 and block the rotation of the transmission component 114. With this configuration, pressing button 1162 rotates stop plate 1161 to control the switching of limit component 116 between limit state and release state. When limit component 116 is in limit state, stop plate 1161 is located on the rotation path of transmission component 114 to prevent transmission component 114 from rotating. As a result, transmission component 114 cannot drive pot lid 113 to rotate, thereby limiting pot lid 113 in the locked position.

[0046] Exemplarily, the transmission assembly 114 is provided with an outwardly extending follower 1141, and the stop plate 1161 limits the transmission assembly 114 by abutting against the follower 1141, thereby limiting the pot lid 113 in the locked position. Exemplarily, the transmission assembly 114 is provided with a limiting hole, and the stop plate 1161 limits the transmission assembly 114 by extending into the limiting hole, thereby limiting the pot lid 113 in the locked position.

[0047] Please see Figure 3In some embodiments of this application, the limiting component 116 further includes a first elastic member 1163. The first elastic member 1163 is mounted on the cover 112 and abuts against the end of the stop plate 1161 near the driven member 1141, so that the end of the stop plate 1161 near the driven member 1141 tends to move towards the driven member 1141. With this configuration, the elastic force of the first elastic member 1163 allows the stop plate 1161 to more stably block the rotation of the driven member 1141, thereby allowing the pot lid 113 to be more stably positioned in the locked position.

[0048] It should be noted that the driven member 1141 can be sleeved on the outer surface of the transmission member 1144. The lower end of the driven member 1141 is connected to the pot lid 113 for transmission, so that the pot lid 113 can be rotated under the drive of the transmission member 1144. At this time, the outer peripheral wall of the driven member 1141 is provided with a groove. When the limiting component 116 is in the limiting state, one end of the stop plate 1161 extends into the groove to limit the driven member 1141. Alternatively, the driven member 1141 can be provided with a fork 1142 on its outer peripheral wall. The fork 1142 is connected to the pot lid 113 for transmission, so that the pot lid 113 can be rotated under the drive of the driven member 1141. At this time, when the limiting component 116 is in the limiting state, the stop plate 1161 blocks the rotation of the fork 1142 to limit the driven member 1141. These are not all listed here.

[0049] Please see Figure 6 In some embodiments of this application, the transmission assembly 114 includes a driven member 1141 and a transmission member 1144. The driven member 1141 is rotatably mounted on the inner cover 111 and is throttle-connected to the pot lid 113. The transmission member 1144 is vertically mounted on the driven member 1141 to switch between a locked position and a released position. The centerline of the transmission member 1144 is collinear with the rotation axis of the driven member 1141. One of the transmission member 1144 and the driven member 1141 is provided with a helical groove 11. 45. Another of the transmission component 1144 and the driven component 1141 is provided with a driving part 1146. The driving part 1146 is inserted into the spiral groove 1145. When the transmission component 1144 switches from the locked position to the released position, the transmission component 1144 drives the driven component 1141 to rotate through the cooperation of the driving part 1146 and the spiral groove 1145, and drives the pot lid 113 to rotate from the locked position to the unlocked position. When the limiting component 116 is in the limiting state, the stop plate 1161 limits the driven component 1141.

[0050] With this configuration, the user only needs to operate the transmission component 1144 to move it in the lifting direction, so that the transmission component 1144 switches from the locked position to the released position. The transmission component 1144, through the cooperation of the drive unit 1146 and the spiral groove 1145, drives the driven component 1141 to rotate, thereby rotating the pot lid 113, so that the pot lid 113 switches from the locked position to the unlocked position. The user can open the upper cover 11 by continuing to pull the transmission component 1144. At the same time, when closing the upper cover 11, the user only needs to close the upper cover 11 by using the transmission component 1144. The transmission component 1144 is switched from the released position to the locked position. The transmission component 1144 drives the driven component 1141 to rotate through the cooperation of the drive part 1146 and the spiral groove 1145, thereby causing the pot lid 113 to rotate, so that the pot lid 113 is switched from the unlocked position to the locked position, which makes it easier for the user to use the cooking utensil 1. The transmission component 1144 drives the driven component 1141 to rotate through the cooperation of the drive part 1146 and the spiral groove 1145, which reduces the structural settings of the transmission part and simplifies the overall structure of the upper cover 11.

[0051] It should be noted that the transmission component 1144 moves up and down along its centerline. The centerline of the transmission component 1144 is collinear with the rotation axis of the driven component 1141. This can be understood as the driven component 1141 rotating around the centerline of the transmission component 1144. The transmission component 1144 can move on the rotation axis of the pot lid 113, or it can move at a position radially spaced from the rotation axis of the pot lid 113. No specific limitation is made here.

[0052] It is understood that the driving part 1146 can be disposed on the transmission member 1144, in which case the helical groove 1145 is disposed on the driven member 1141; alternatively, the driving part 1146 can be disposed on the driven member 1141, in which case the helical groove 1145 is disposed on the transmission member 1144. Preferably, the driving part 1146 is cylindrical, which can reduce the wear between the outer peripheral wall of the driving part 1146 and the groove wall of the helical groove 1145. It should be noted that the downward projection of the helical groove 1145 is located on the circumference of a circle, and the center line of the transmission member 1144 in this application is a line extending along its own lifting direction and passing through the center of the aforementioned circle.

[0053] When the top cover 11 is opened, the user operates the transmission component 1144 to move in the lifting direction to switch from the locked position to the released position. The transmission component 1144 drives the driven component 1141 to rotate through the drive part 1146 and the spiral groove 1145, thereby rotating the pot lid 113 and switching the pot lid 113 from the locked position to the unlocked position. The user can open the top cover 11 by continuing to operate the transmission component 1144 in the lifting direction.

[0054] When the upper cover 11 is closed, the user operates the transmission component 1144 to close the upper cover 11 to the inner pot 123. Then, the user operates the transmission component 1144 to move in the lifting direction to switch from the released position to the locked position. The transmission component 1144 drives the driven component 1141 to rotate through the cooperation of the drive part 1146 and the spiral groove 1145, thereby causing the pot lid 113 to rotate, so that the pot lid 113 switches from the unlocked position to the locked position.

[0055] Please see Figure 6 as well as Figure 7 In some embodiments of this application, the upper cover 11 further includes a hanging shaft 117, which connects the driven member 1141 and the pot lid 113. The pot lid 113 is rotatably disposed below the cover body via the hanging shaft 117. The driven member 1141 is connected to a fork 1142, which extends from the driven member 1141 toward the edge of the pot lid 113. The fork 1142 is provided with a drive groove 1143. The pot lid 113 is connected to a lever 1131, which is spaced apart from the rotation axis of the pot lid 113 and is movably inserted into the drive groove 1143. When the limiting component 116 is in the limiting state, the end of the stop plate 1161 near the fork 1142 is located on the rotation path of the fork 1142 to block the rotation of the fork 1142. This embodiment features a relatively simple structure that allows the lid 113 to be rotatably mounted below the lid body. The connection structure is simple, and the lid 113 is rotated by a lever 1131 driven by a fork 1142. Due to its long lever arm, the torque during the driving process is large, resulting in a more stable and smoother lid-opening operation. Simultaneously, the stop plate 1161 limits the driven member 1141 by preventing the fork 1142 from rotating, fully utilizing the space in the rotation direction of the fork 1142. This results in larger gaps between components, providing more operational space for assembling the lid 11 and thus improving the assembly efficiency of the lid 11.

[0056] Preferably, there is a movement gap a between the lid 113 and the hanging shaft 117, where a > 2 mm. With this arrangement, only one hanging shaft 117 is suspended on the transmission mechanism, and the lid 113 can move up and down relative to the hanging shaft 117. This ensures that the lid 113 does not come into contact with the inner lid 111 or other supporting components such as the transmission mechanism when it is under pressure or heat, thereby reducing the impact of lid 113 deformation on the opening and closing force.

[0057] Please see Figure 3 as well as Figure 6In some embodiments of this application, a limiting rib 1111 protrudes from the surface of the inner cover 111 facing away from the pot body 12. The limiting rib 1111 and the surface of the inner cover 111 form a limiting groove 1112. The fork 1142, the lever 1131, and the limiting assembly 116 are all located within the limiting groove 1112. It is understood that the transmission member 1144 and the driven member 1141 are both disposed on the surface of the inner cover 111 facing away from the pot body 12. The inner cover 111 is provided with a clearance channel that extends circumferentially along the pot cover 113. The lever 1131 passes through the clearance channel and engages with the fork 1142. With this configuration, the limiting rib 1111 can limit the rotation of the lever 1131, preventing the lever fork 1142 from rotating too much and colliding with other components inside the upper cover 11. At the same time, the limiting rib 1111 can protect the limiting component 116 and the lever fork 1142, preventing other components from interfering with the limiting component 116.

[0058] Please see Figure 7 In some embodiments of this application, the upper cover 11 further includes at least one elastic push rod 118. The elastic push rod 118 includes a second elastic element 1181 and a push block 1182. One end of the second elastic element 1181 abuts against the surface of the inner cover 111 facing the pot body 12, and the other end of the second elastic element 1181 is connected to the push block 1182. When the upper cover 11 is placed on the pot body 12 and not in operation, the push block 1182 and the pot cover 113 are in clearance fit. When the upper cover 11 is placed on the pot body 12 and in operation, the push block 1182 abuts against the pot cover 113. With this configuration, when the top cover 11 is placed on the pot body 12 and not in operation, the top block 1182 and the pot lid 113 are spaced apart, making it easy for the user to place the top cover 11 on the pot lid 113. Furthermore, the pot lid 113 will not rub against the top block 1182 when switching between the unlocked and locked positions, thereby reducing the resistance to the rotation of the pot lid 113. This reduces the resistance for the user to pull the handle 115 to drive the transmission component 114 to rotate the pot lid 113, thus making it easier for the user to operate the top cover 11. When the upper cover 11 is placed on the pot body 12 and is in operation, the pot lid 113 will move upward under the action of the air pressure in the cooking cavity 13 and abut against the top block 1182. The top block 1182 will buffer the movement of the pot lid 113 under the action of the elastic force of the second elastic element 1181. At the same time, after the cooking appliance 1 is depressurized, the top block 1182 will drive the pot lid 113 to move downward under the action of the elastic force of the second elastic element 1181, thereby reducing the squeezing force between the pot lid 113 and the outer pot 122 and reducing the resistance of the outer pot 122 to the pot lid 113. This makes it easier for the user to pull the handle 115 to drive the transmission component 114 to switch the pot lid 113 from the locked position to the unlocked position, which makes it easier for the user to open the cooking appliance 1.

[0059] Considering that even after the lid 11 is opened, the handle 115 can still rotate the pot lid 113, the pot lid 113 may switch to the locked position when the lid 11 is opened. Consequently, when the lid 11 closes the pot body 12, the pot lid 113 may be in the locked position, interfering with the pot body 12 and preventing it from closing. Therefore, please refer to [link / reference needed]. Figure 6 as well as Figure 8 The pot lid 113 is provided with an anti-rotation part 1132, and the upper cover 11 also includes an anti-rotation block 119, which is slidably installed on the inner cover 111. When the upper cover 11 is not placed on the pot body 12, the anti-rotation block 119 cooperates with the anti-rotation part 1132 to prevent the pot lid 113 from rotating. When the upper cover 11 is placed on the pot body 12, the outer shell 121 abuts against the anti-rotation block 119, driving the anti-rotation block 119 to move away from the outer shell 121, so that the anti-rotation block 119 disengages from the anti-rotation part 1132.

[0060] With this configuration, when the lid 11 opens the pot body 12, the anti-rotation block 119 cooperates with the anti-rotation part 1132 to limit the lid 113, keeping it in the unlocked position. This prevents interference between the lid 113 and the pot body 12 when the lid 11 closes, facilitating user operation of the cooking appliance 1 and preventing the lid 113 from rotating and injuring the user. Simultaneously, when the lid 113 is limited, the transmission component 114 also limits the handle 115. After the lid 11 closes the pot body 12, the outer shell 121 abuts against the anti-rotation block 119, driving the anti-rotation block 119 to disengage from the anti-rotation part 1132. This allows the lid 113 to rotate, switching between the locked and unlocked positions without requiring manual unlocking by the user, thus facilitating user operation of the cooking appliance 1.

[0061] It should be noted that there are many ways in which the anti-rotation part 1132 and the anti-rotation block 119 can be coupled. The anti-rotation part 1132 and the anti-rotation block 119 can be inserted together, or they can be abutted together; no specific limitation is made here. For example, one of the anti-rotation part 1132 and the anti-rotation block 119 can be a groove, and the other can be a protrusion. The protrusion and the groove can be inserted together to limit the position of the pot lid 113. Alternatively, the anti-rotation block 119 can be inserted into the rotation path of the anti-rotation part 1132, so that the anti-rotation block 119 abuts against the anti-rotation part 1132, thereby limiting the position of the pot lid 113.

[0062] Specifically, please refer to Figure 8The anti-rotation block 119 includes a main body 1191, an abutment portion 1192, a connecting portion 1193, and a limiting portion 1194. The main body 1191 is slidably mounted on the inner cover 111. The abutment portion 1192 is disposed at one end of the main body 1191 near the outer shell 121. The connecting portion 1193 is disposed on the outer peripheral wall of the main body 1191 and located between the inner cover 111 and the pot lid 113. The limiting portion 1194 is disposed on the surface of the connecting portion 1193 facing the pot lid 113. When the upper cover 11 is not placed on the pot body 12, the limiting portion 1194 cooperates with the anti-rotation portion 1132 to prevent the pot lid 113 from rotating. When the upper cover 11 is placed on the pot body 12, the outer shell 121 abuts against the abutment portion 1192, driving the main body 1191 to move away from the outer shell 121, so that the limiting portion 1194 disengages from the anti-rotation portion 1132. With this configuration, the abutment part 1192 and the limiting part 1194 are spaced apart radially on the lid 113 by the connecting part 1193, thereby avoiding interference between the abutment part 1192 and the lid 113 and affecting the rotation of the lid 113.

[0063] Please see Figure 6 In some embodiments of this application, the upper cover 11 further includes a first reset member 11a, which abuts against the anti-rotation block 119, causing the anti-rotation block 119 to tend to move closer to the outer shell 121. With this configuration, when the upper cover 11 opens the pot body 12, the first reset member 11a pushes the anti-rotation block 119 closer to the outer shell 121, allowing the anti-rotation block 119 to stably engage with the anti-rotation part 1132 to limit the pot cover 113, thus eliminating the need for the user to manually switch the position of the anti-rotation block 119, thereby facilitating the user's operation of the cooking appliance 1. It should be noted that one end of the first reset member 11a abuts against the anti-rotation block 119, and the other end of the first reset member 11a can abut against the top cover 112 or the inner cover 111; no specific limitations are made here.

[0064] Please see Figure 9 In some embodiments of this application, the top cover 11 further includes a control component 11b, which is installed inside the handle 115 and electrically connected to the pot body 12. This arrangement, by installing the control component 11b inside the handle 115, fully utilizes the space within the handle 115, thereby simplifying the structure of the top cover 11. The control component 11b can be one or more of a display, button 1162, circuit board, etc. The control component 11b can be electrically connected to the pot body 12 via wires, or wirelessly connected via Bluetooth, WiFi, etc., without specific limitations.

[0065] Please see Figure 6 as well as Figure 7In some embodiments of this application, the outer peripheral wall of the cover 112 is provided with a clearance hole 1121, and the outer peripheral wall of the pot lid 113 is provided with a driving protrusion 1133; the outer peripheral wall of the outer shell 121 is provided with a limiting protrusion 1211, the limiting protrusion 1211 is provided with a receiving groove 1212, and the groove wall of the receiving groove 1212 away from the outer pot 122 is provided with a limiting hole 1213; the upper cover 11 also includes a pin 11c, the pin 11c is telescopically installed on the inner side of the inner cover 111, and one end of the pin 11c can pass through the clearance hole 1121 and extend out of the cover 112; wherein, when the upper cover 11 is placed on the outer pot 122 and the pot lid 113 is switched from the unlocked position to the locked position, the pin 11c is located in the receiving groove 1212, and the driving protrusion 1133 drives the pin 11c to move away from the pot lid 113, and the end of the pin 11c away from the pot lid 113 extends into the limiting hole 1213.

[0066] With this configuration, when the upper cover 11 closes the pot body 12 and the pot lid 113 switches from the unlocked position to the locked position, the rotation of the pot lid 113 causes the drive protrusion 1133 to abut against the end of the pin 11c near the pot lid 113, thereby driving the pin 11c to move away from the pot lid 113. This causes the end of the pin 11c extending out of the cover 112 to enter the limiting hole 1213, thus locking the pot body 12 and the upper cover 11 together through the pin 11c. When the cooking appliance 1 is working, the air pressure in the cooking cavity 13 rises, causing the upper cover 11 to tend to move upward. The pin 11c connects the upper cover 11 to the outer shell 121, thereby preventing the upper cover 11 from detaching from the pot body 12. At the same time, the outer shell 121 can share some of the squeezing force brought by the air pressure in the cooking cavity 13 for the locking of the pot lid 113 and the outer pot 122, thereby extending the service life of the pot lid 113 and the outer pot 122. Meanwhile, the pin 11c is located inside the cover 112, so that the cover 112 can protect the pin 11c.

[0067] Further, please refer to Figure 7 The upper cover 11 also includes a second reset member 11d, which abuts against the pin 11c, causing the pin 11c to tend to move closer to the lid 113. With this configuration, when the upper cover 11 is opened and the lid 113 is switched to the unlocked position, the second reset member 11d pushes the pin 11c closer to the lid 113, causing the pin 11c to exit the limiting hole 1213. This eliminates the need for the user to manually switch the position of the pin 11c, thus facilitating user operation of the cooking appliance 1. It should be noted that one end of the second reset member 11d abuts against the pin 11c, while the other end of the second reset member 11d can abut against the top cover 112 or the inner cover 111; no specific limitation is made here.

[0068] Please see Figure 6In some embodiments of this application, the upper cover 11 further includes a mounting member 11e, which is mounted on the outer peripheral wall of the inner cover 111 and has a through hole 111e. A pin 11c is movably mounted on the mounting member 11e, with one end of the pin 11c passing through the through hole 111e and the other end passing through a clearance hole 1121. This configuration allows the pin 11c to move axially within the limits of the through hole 111e and the clearance hole 1121, preventing the pin 11c from disengaging from the mounting member 11e.

[0069] Further, please refer to Figure 7 The pin 11c is provided with a limiting ring 111c. When the pot lid 113 is in the unlocked position, the limiting ring 111c abuts against the mounting part 11e. This configuration limits the pin 11c by the abutting between the limiting ring 111c and the mounting part 11e, preventing the pin 11c from extending too far and colliding with the pot lid 113, thus avoiding wear on the pot lid 113.

[0070] Please see Figure 1 In some embodiments of this application, the lower surface of the mounting member 11e is provided with a positioning part 112e, and the bottom of the receiving groove 1212 is provided with a mating part 1214. The positioning part 112e and the mating part 1214 are inserted into each other. With this configuration, when the upper cover 11 closes the pot body 12, the positioning part 112e will be inserted into the mating part 1214 to position the upper cover 11 radially, ensuring that the pin 11c is aligned with the limiting hole 1213, so that the end of the pin 11c away from the pot cover 113 can accurately extend into the limiting hole 1213.
