Description

Technical Field

[0001] This disclosure relates to the field of cooking appliance technology, and more particularly to a pot lid assembly and a cooking appliance. Background Technology

[0002] Currently, operating structures typically include slides and operating components, allowing adjustment of the operating components' position on the track and thus the operating state of the structure. However, adjusting the operating components can easily expose the components on the back of the operating structure, affecting aesthetics and user experience. Conversely, if the dimensions along the operating structure's movement direction are too long, while this can conceal the components on the back, it results in an excessively large overall size, impacting installation space.

[0042] A cooking appliance is provided according to a second aspect of the embodiments of this disclosure, comprising:

[0043] The pot lid assembly as described in the above technical solution.

[0044] Compared to existing technologies, this disclosure offers at least the following advantages: The pot lid assembly provided in this embodiment includes a shell, a lid body, an operating structure, and an operating part. The shell comprises an outer shell and an inner shell, with the outer shell located outside the inner shell. The inner shell is rotatably connected to the lid body, and the lid body can be rotated relative to the shell via the operating structure. Specifically, the outer shell has a panel with a passage opening. The operating structure includes a guide rail and an operating part. The guide rail is located within an installation space and may include a first blocking member and a guide member. The first blocking member and the passage opening are opposite to each other, and the guide member is positioned between the first blocking member and the panel. A gap is formed between the first blocking member and the guide member, and a guide groove is defined by their cooperation. The operating part can move along the direction of the guide groove. Specifically, the operating part may include an operating end and a driving end. The operating end is movably inserted through the passage opening and can be driven to the lid body via the driving end, ensuring smooth adjustment of the operating end position by the user. The user can rotate the lid by adjusting the operating end extending from the passage opening, thereby allowing the lid to rotatably engage with the pot body or rotate to detach from the pot body. Throughout the operation, the passage opening is blocked by the first shielding component, preventing the user from seeing the side of the shielding component away from the operating part through the passage opening. This improves the overall aesthetics of the pot lid assembly and the cooking appliance, and prevents external impurities, oil, water, etc., from entering the cooking appliance through the passage opening during cooking, which would be difficult to clean and could even affect the normal operation of the appliance's components, contaminating the cooked food. Furthermore, compared to increasing the size of the operating component in the direction of movement of the guide rail to block the back of the operating component during adjustment, this technical solution saves on the size of the operating component in the direction of movement, thus improving the structural compactness of the operating structure and facilitating the overall miniaturization design of the pot lid assembly.

[0073] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0074] In some examples, the operating structure 100 may include an operating member 132 and a track for the operating part 130 to slide. The panel 110 has a passage opening 1111 through which the operating member 132 can pass. The user can operate the driven component by adjusting the position of the operating member 132 extending from the passage opening 1111 on the track. If the operating member 132 is designed to be too short along the guide direction of the track, the structure on the back of the operating member 132 will be exposed when sliding, affecting the overall aesthetics of the operating structure 100. When the length of the operating member 132 is more than twice the length of the sliding track, the structure on the back of the operating member 132 corresponding to the passage opening 1111 can be consistently covered when the operating member 132 slides along the track. However, this greatly increases the size of the operating structure 100 and the overall size of the component on which the operating structure 100 is mounted, occupying a large space and hindering miniaturization design. To solve the above technical problems, this application proposes an operating structure 100.

[0075] like Figures 1 to 5 As shown, a pot lid assembly is provided according to a first aspect of the present disclosure, comprising: a housing 200 having a passage 1111 and an installation space, the passage 1111 communicating with the installation space; a lid rotatably disposed on the housing 200; and an operating structure comprising: a guide rail portion 120 disposed within the installation space, the guide rail portion 120 including a first blocking member 121 and a guide member 122, the first blocking member 121 being arranged opposite to the passage 1111, the guide member 122 being disposed between the first blocking member 121 and the panel 110, and a guide groove 123 being defined between the first blocking member 121 and the guide member 122; and an operating portion 130 movably disposed in the guide groove 123, the operating end of the operating portion 130 being movably inserted through the passage 1111, and the driving end of the operating portion 130 being used for transmission connection to the lid.

[0076] It is understood that the pot lid assembly 100 provided in this embodiment includes a housing 200, a lid, an operating structure, and an operating part 130. The housing 200 has an outer shell and an inner shell, with the outer shell located outside the inner shell. The inner shell is rotatably connected to the lid, and the lid can be rotated relative to the housing 200 via the operating structure. Specifically, the outer shell has a panel 110, and a passage opening 1111 may be formed at the panel 110. The operating structure has a guide rail portion 120 and an operating part 130. The guide rail portion 120 is disposed within the installation space and may have a first blocking member 121 and a guide member 122. The first blocking member 121 and the passage opening 1111 are opposite to each other, and the guide member 122 may be disposed between the first blocking member 121 and the panel 110. A gap is formed between the first blocking member 121 and the guide member 122, and a guide groove 123 is defined by the cooperation of the first blocking member 121 and the guide member 122. The operating part 130 can move along the direction of the guide groove 123. Specifically, the operating part 130 can be provided with an operating end and a driving end. The operating end can be movably inserted through the passage 1111 and can be connected to the lid through the driving end to ensure smooth adjustment of the operating end position by the user. By adjusting the operating end extending from the passage 1111, the user can drive the lid to rotate through the driving end, thereby allowing the lid to be rotated and fastened to the pot body, or to rotate the lid to separate it from the pot body. During the entire operation, the passage 1111 is blocked by the first shielding member 121, preventing the user from seeing the side of the first shielding member 121 away from the operating part 130 through the passage 1111. This improves the overall aesthetics of the pot lid assembly 100 and the cooking appliance, and prevents external impurities, oil, water, etc. from entering the cooking appliance through the passage 1111 during the cooking process. This would make it difficult to clean and could even affect the normal operation of the cooking appliance's parts, contaminating the cooked food. Meanwhile, compared to increasing the size of the operating component in the direction of movement of the guide rail 120, so as to block the back side of the operating component during the adjustment of the operating component, this technical solution can save the size of the operating component in the direction of movement, thereby improving the structural compactness of the operating structure and facilitating the overall miniaturization design of the pot lid assembly 100.

[0077] For example, the panel 110 can be integrated with the housing 210, avoiding the need for multiple layers in the housing 200 structure and improving the overall aesthetics and structural strength.

[0078] In some examples, such as Figure 2 As shown, in the projection plane perpendicular to the conduction direction of the aforementioned through-hole 1111, the orthographic projection of the aforementioned through-hole 1111 is located within the orthographic projection of the aforementioned first blocking member 121.

[0079] It is understandable that, on the projection plane perpendicular to the guiding direction of the passage 1111, the orthographic projection of the passage 1111 on the projection plane lies within the orthographic projection of the first blocking member 121 on the projection plane. That is, along the guiding direction of the passage 1111, the size of the first blocking member 121 is larger than the size of the passage 1111. This arrangement ensures that when the user observes the passage 1111 along its guiding direction, the first blocking member 121 can completely block the structure on the back side of the passage 1111, guaranteeing the blocking effect of the first blocking member 121 and improving reliability and the overall aesthetics of the operating structure 100.

[0080] In some examples, such as Figure 1 and Figure 2 As shown, the above-mentioned operating structure further includes: a second shielding member 112, which is disposed on the side of the housing 200 facing the guide rail portion 120, and the second shielding member 112 is located between the guide member 122 and the operating end.

[0081] Understandably, the housing is provided with a panel 110, which serves as the exterior surface of the operating structure 100. The outer wall of the panel 110 may have a passage opening 1111, through which the operating member 132 may pass. The second blocking member 112 may be provided on the side of the panel 110 facing the guide rail portion 120, and the second blocking member 112 may be provided between the guide member 122 and the operating end of the operating portion 130. By setting the first shielding member 121 to shield the structure located on the back side of the operating part 130, and by setting the second shielding member 112 to shield the structure located on the side of the operating part 130, the shielding area is increased. This ensures that when the user observes the passage 1111 from multiple angles, the structures located on the back and sides of the operating part 130 are completely shielded, further improving the overall aesthetics. It also prevents external impurities, oil, water, and other substances from entering the cooking appliance from the side of the passage 1111 during the cooking process, which would be difficult to clean and could even affect the normal operation of the cooking appliance's parts, thus contaminating the cooked food.

[0082] In some examples, such as Figure 14 As shown, the operating unit 130 includes: a support plate 131, including a mating section 1311 and a main body section 1312 connected to the mating section 1311, the mating section 1311 being movably disposed in the guide groove 123, and the main body section 1312 being arranged corresponding to the passage 1111; an operating member 132, disposed on the support plate 131, with the operating end formed on the operating member 132; and a connecting member 133, disposed on the side of the mating section 1311 away from the main body section 1312, with the driving end formed on the connecting member 133.

[0083] It is understood that the operating unit 130 may also be provided with a support plate 131, an operating member 132, and a connecting member 133. The support plate 131 may be provided with a mating section 1311 and a main body section 1312. Specifically, the operating member 132 may be disposed on the main body section 1312, which is positioned corresponding to the passage opening 1111, allowing the operating member 132 to pass through the passage opening 1111 without interference, ensuring smooth operation of the operating member 132. The mating section 1311 may be connected to the main body section 1312 and located beside it. The mating section 1311 may be inserted into the guide groove 123 defined between the first blocking member 121 and the guide member 122. The connecting member 133 may be disposed on the side of the mating section 1311 away from the main body section 1312, and a connecting member 133 may be formed on the connecting member 133, which is used for transmission connection to the component to be driven. With this configuration, when the user operates the operating component 132, the operating component 132 can drive the support plate 131 to move. Under the action of the guide groove 123, the mating section 1311 slides along the guiding direction of the guide groove 123, ensuring that the movement of the operating component 132 is stable and reliable. Furthermore, while the operating component 132 drives the support plate 131 to move, it will change the position of the connecting component 133, thereby changing the state of the driven part through the driving end.

[0084] It should be noted that the second shielding member 112 can shield the mating section 1311 and the connecting member 133 located on the side of the mating section 1311 away from the main body section 1312, ensuring the shielding effect of the second shielding member 112. This ensures that when the user observes the passage 1111 from multiple angles, the structure located next to the passage 1111 is completely shielded, further improving the overall aesthetics.

[0085] It is understandable that a transmission component may be provided at the lid, which is used to drive the lid to rotate. The drive end of the operating part 130 may be connected to the transmission component. By adjusting the operating part 132 extending out of the through port 1111, the transmission component can drive the lid to rotate, thereby allowing the lid to be rotatably fastened to the pot body, or allowing the lid to rotate to separate from the pot body.

[0086] In some examples, such as Figures 11 to 13 As shown, at least a portion of the aforementioned connector 133 is located outside the aforementioned guide groove 123.

[0087] Understandably, a portion of the connector 133 may extend out of the guide groove 123 and be located outside the guide groove 123. This arrangement ensures that a portion of the connector 133 is located outside the passage opening 1111, and the guide member 122 blocks the connector 133 near the passage opening 1111. The second blocking member 112 blocks the side of the passage opening 1111, ensuring that the user will not see the connector 133 exposed when observing the passage opening 1111.

[0088] It should be noted that the connector 133 located outside the guide groove 123 can be formed, and is connected to the driven component through the connector 133. When the user operates the operating component 132 to move, the support plate 131 can be moved synchronously, and the connector 133 also moves accordingly. The movement of the connector 133 is blocked by the guide component 122 and the second blocking component 112. This makes the layout of the operating structure 100 more reasonable while ensuring the blocking effect of the connector 133, further improving the aesthetics.

[0089] In some examples, such as Figure 17 As shown, the support plate 131 has a bent section 1313. The bent section 1313 bends towards the end of the first shield 121 away from the housing 200. The bent section 1313, together with the end of the support plate 131 away from the housing 200, clamps the side of the first shield 121. The support plate 131 also includes a bent section 1313. The mating section 1311 connects the main body section 1312 and the bent section 1313. The bent section 1313 is located outside the guide groove 123 and bends towards the side of the first shield 121 away from the passage opening 1111. A portion of the bent section 1313 is located on the side of the first shield 121 away from the passage opening 1111.

[0090] It is understood that the support plate 131 may include a bent section 1313. Specifically, the bent section 1313 bends toward the side of the first blocking member 121 away from the passage opening 1111. A clamping space can be formed between the bent section 1313 and the side of the support plate 131 away from the passage opening 1111. The size of the clamping space matches the side size of the first blocking member 121, so that the side of the first blocking member 121 can be clamped by the bent section 1313 in conjunction with the end of the support plate 131 away from the housing 200. This further improves the reliability of the cooperation between the operating part 130 and the guide rail part 120, which is conducive to the stable movement of the operating part 130.

[0091] In some examples, such as Figure 3 and Figure 6 As shown, the guide rail portion 120 further includes a limiting cover 140, which has a first slot 141 and a second slot 142. Along the extending direction of the guide groove 123, one end of the first blocking member 121 is inserted into the first slot 141, and one end of the guide member 122 is inserted into the second slot 142. The limiting cover 140 is used to abut against the operating portion 130.

[0092] It is understandable that the guide rail 120 may also be provided with a limiting cover 140. Specifically, the limiting cover 140 may be provided with a first slot 141 and a second slot 142 in the direction facing the operating member 132, and along the extension direction of the guide groove 123, the top end of the first blocking member 121 may be inserted into the first slot 141, and the top end of the guide member 122 may be inserted into the second slot 142, with the first slot 141 and the second slot 142 spaced apart. With this arrangement, the distance between the first blocking member 121 and the guide member 122 can be limited by the limiting cover 140, thereby ensuring that the size of the guide groove 123 defined between the first blocking member 121 and the guide member 122 is fixed, preventing the distance between the first blocking member 121 and the guide member 122 from changing after long-term use of the operating structure 100, which would cause the operating member 130 to fall out of the guide groove 123 or increase the sliding resistance, thus improving stability.

[0093] It should be noted that a partition 143 may be provided between the first slot 141 and the second slot 142, and the width of the partition 143 is the same as the width of the guide groove 123. When the operating part 130 slides in the guide groove 123, the operating part 130 can abut against the side of the limiting cover 140 located in front of the guide member 122. This restricts the operating part 130 from sliding upward and prevents it from falling out of the guide groove 123, thus improving stability. Furthermore, the length of the limiting cover 140 on the back of the first shield 121 is greater than the length of the limiting cover 140 on the front of the guide member 122. This improves the support effect of the limiting cover 140 on the first shield 121, increases structural strength, reduces deformation, and reduces the restriction on the travel of the operating part 130, ensuring that the operating part 130 has a sufficient range of motion so that the connecting member 133 can fully transmit power to the driven component, ensuring that the driven component achieves the set driving effect. For example, when the operating structure 100 is installed on a pot lid with the handle being a cooking utensil, the operating part 130 has a sufficient range of motion to ensure the transmission effect of the connector 133 on the driven component, thereby allowing the lid to be rotated to be securely fastened to the pot body through the driven component, ensuring a tight connection, and allowing the lid to be rotated to be completely separated from the pot body, ensuring that the pot lid can be easily removed.

[0094] It should be noted that the limiting cover 140 can be located outside the access port 1111 so that the limiting cover 140 can be covered by the panel 110 to ensure aesthetics.

[0095] In some examples, such as Figure 5 As shown, the limiting cover 140 and the housing are integrally formed; or the panel 110 forms a limiting rib 144, and the limiting cover 140 is connected to the limiting rib 144 and located between the limiting rib 144 and the passage 1111.

[0096] It is understandable that the limiting cover 140 and the panel 110 can be designed as an integrated structure, formed integrally by stamping or injection molding to ensure the structural strength of the limiting cover 140 and the panel. The panel 110 can also have a limiting rib 144. Specifically, the limiting rib 144 protrudes from the back side of the panel 110, and the limiting cover 140 can be connected to the limiting rib 144 by screwing, welding, or gluing. The limiting cover 140 can be located between the limiting rib 144 and the through-hole 1111, so that the limiting cover 140 is covered by the through-hole 1111, ensuring that the user will not notice the limiting cover 140 when observing the panel 110, thus improving aesthetics.

[0097] In some examples, such as Figure 2 As shown, the pot lid assembly 100 further includes a transmission unit 160, which is connected to the drive end of the operation unit 130 and the component to be driven.

[0098] It is understood that the operating structure 100 may also be provided with a transmission unit 160. Specifically, the transmission unit 160 may be connected to the drive end of the operating unit 130, and the transmission unit 160 may transmit the driving force of the drive end to the driven component, thereby enabling the operating unit 130 to drive the driven component through the transmission unit 160.

[0099] In some examples, such as Figures 7 to 16 As shown, the transmission unit includes: a limiting seat 161, disposed in the installation space, close to the housing 200, located on the side of the first shielding member 121 opposite to the passage 1111, with a limiting hole formed in the side wall of the limiting seat 161; a first rotating shaft 163, inserted into the limiting hole; a connecting handle 162, disposed on the first rotating shaft 163, with a waist-shaped groove 1621 formed at the end of the connecting handle 162 away from the first rotating shaft 163, and the driving end movably disposed in the waist-shaped groove 1621; a first bevel gear 164, disposed at one end of the first rotating shaft 163; a bearing seat 166, disposed on the cover; a second rotating shaft 167, rotatably disposed on the bearing seat 166; and a second bevel gear 168, disposed on the second rotating shaft 167 and meshing with the second bevel gear 168.

[0100] Understandably, the transmission unit 160 may be provided with a limiting seat 161, a connecting handle 162, a first rotating shaft 163, and a first bevel gear 164. The limiting seat 161 may be disposed in the installation space, close to the panel 110, located on the back side of the first blocking member 121. A limiting hole may be formed in the side wall of the limiting seat 161, into which the first rotating shaft 163 is inserted, thereby limiting the radial movement of the first rotating shaft 163, allowing the first rotating shaft 163 to be rotatably disposed on the limiting seat 161. The connecting handle 162 may be disposed on the first rotating shaft 163, and the connecting handle 162 may rotate synchronously with the first rotating shaft 163. A waist-shaped groove 1621 may be formed at the end of the connecting handle 162 away from the first rotating shaft 163, and the driving end of the operating unit 130 may be movably disposed in the waist-shaped groove 1621. The first bevel gear 164 is disposed at one end of the first rotating shaft 163, and the first bevel gear 164 is used to mesh with the second bevel gear 168 of the component to be driven. With this configuration, when the operating part 130 slides in the guide groove 123, the driving end of the operating part 130 moves in the waist-shaped groove 1621, thereby causing the connecting handle 162 to swing and drive the first rotating shaft 163 to rotate. The first rotating shaft 163 drives the first bevel gear 164 to rotate, and the first bevel gear 164 drives the second bevel gear 168 to rotate, so that the lid is driven to rotate through the second bevel gear 168, thereby changing the relative position of the lid and the pot, so that the lid is fastened to the pot or separated from the pot.

[0101] In some examples, such as Figures 7 to 16 As shown, the transmission part 160 further includes a stop block 165, the limiting seat 161 is provided with a limiting groove 1611, the stop block 165 is inserted into the limiting groove 1611, and the stop block 165 is sleeved on the first rotating shaft 163.

[0102] Understandably, the transmission unit 160 may also be provided with a stop 165, which can be sleeved on the end of the first rotating shaft 163 and located outside the connecting handle 162. Correspondingly, the limiting seat 161 may be provided with a limiting groove 1611, and the stop 165 can be inserted into the limiting groove 1611. The stop 165 can restrict the axial movement of the first rotating shaft 163 in the limiting seat 161, effectively improving the skipping tooth phenomenon. The size of the stop 165 is larger than the area of ​​the limiting hole to prevent the stop 165 from passing through the limiting hole. A small gap may be left between the stop 165 and the limiting seat 161, so that the contact area between the stop 165 and the limiting seat 161 is small, reducing friction and ensuring smooth rotation of the first rotating shaft 163.

[0103] In some examples, in the projection plane perpendicular to the axial direction of the first rotation axis 163, the orthographic projection of the first rotation axis 163 and the orthographic projection of the limiting hole are both located within the orthographic projection of the stop.

[0104] It is understood that the shape of the stop 165 is not limited, only that in the projection plane perpendicular to the axis of the first rotating shaft 163, the projection of the first rotating shaft 163 and the projection of the limiting hole both fall within the projection of the stop 165. When the stop 165 is an annular ring, its outer diameter can be 4mm larger than the outer diameter of the first rotating shaft 163, and its outer diameter can be 3mm larger than the diameter of the limiting hole. Furthermore, to facilitate the installation of the first bevel gear 164, a portion of the stop 165 can be removed from the side facing away from the connecting handle 162, forming a bevel at the end of the stop 165 facing the limiting groove 1611.

[0105] In some examples, such as Figures 7 to 16 As shown, a protrusion 1622 is provided at one end of the waist-shaped groove 1621 away from the first rotating shaft 163.

[0106] It is understandable that the end of the connecting handle 162 away from the first rotating shaft 163 may be provided with a waist-shaped groove 1621, and a protrusion 1622 may be formed at the outer edge of the waist-shaped groove 1621 along the axial direction of the first rotating shaft 163. The protrusion 1622 protrudes out of the plane where the waist-shaped groove 1621 is located, which avoids the outer edge of the waist-shaped groove 1621 being too weak, improves the structural strength, and reduces the radial dimension of the connecting handle 162 along the first rotating shaft 163, which makes it easier to reduce the thickness dimension of the installation space, thereby reducing the overall thickness of the pot lid and improving the aesthetics.

[0107] In some examples, such as Figures 7 to 16 As shown, the small-diameter end of the first bevel gear 164 faces the end of the first rotating shaft 163 near the bearing 166; and / or the small-diameter end of the second bevel gear 168 faces the second rotating shaft 167 and is connected to the end of the bearing 166.

[0108] Understandably, to save installation space at the first bevel gear 164 and the second bevel gear 168, the rotation shaft of the first bevel gear 164 and / or the second bevel gear 168 can be located inside the bevel gear. For example... Figure 7 and Figure 8 As shown, due to the meshing angle and setting direction of the first bevel gear 164 and the second bevel gear 168, the inner side of the second bevel gear 168 faces the plane of the limiting seat 161. The bearing seat 166 of the second bevel gear 168 is set on the outer side of the limiting seat 161. The second rotating shaft 167 of the second bevel gear 168 is rotatably set on the bearing seat 166, so that the second rotating shaft 167 is connected to the inner side of the bevel teeth of the second bevel gear 168, so that the second rotating shaft 167 can be driven to rotate by the second bevel gear 168. This avoids the second rotating shaft 167 being set on the outer side of the bevel teeth of the second bevel gear 168, which would increase the overall height of the transmission part 160 and the driven part, occupy more space, and cause the pot lid to thicken.

[0109] In some examples, the transmission part 160 further includes a nut 169, wherein the second rotating shaft 167 has an external thread on the circumference of one end opposite to the bearing seat 166, and the nut 169 is screwed onto the external thread.

[0110] It is understandable that the portion of the second rotating shaft 167 that extends beyond the bevel teeth of the second bevel gear 168 may be provided with external threads. The nut 169 is screwed onto the thread of the second rotating shaft 167 to prevent the second bevel gear 168 from moving axially along the second rotating shaft 167 and to improve stability.

[0111] In some examples, such as Figure 3 As shown, in the projection plane perpendicular to the conduction direction of the passage 1111, a portion of the orthographic projection of the transmission part 160 is located outside the orthographic projection of the passage 1111; and / or a portion of the transmission part 160 is located on the side of the first shield 121 opposite to the passage 1111.

[0112] Understandably, since the first blocking member 121 can completely block the passageway 1111 in the projection plane perpendicular to the conduction direction of the passageway 1111, it prevents the user from observing the structure on the back of the operation unit 130 from the passageway 1111. Therefore, by placing the transmission unit 160 on the side of the first blocking member 121 opposite to the passageway 1111, the user will not notice the existence of the transmission unit 160 when observing the passageway 1111. Furthermore, in the projection plane perpendicular to the conduction direction of the passageway 1111, the portion of the transmission unit 160 that extends beyond the orthographic projection of the passageway 1111 can be blocked by the panel 110, ensuring the blocking effect of the first blocking member 121.

[0113] According to a second aspect of the present disclosure, a cooking appliance is provided, comprising: a pot lid assembly 200 as described above.

[0114] It is understood that the lid assembly 200 is equipped with the cooking appliance described in the above technical solution, and therefore has all the beneficial effects of the aforementioned cooking appliance, which will not be repeated here. The cooking appliance may also be equipped with a pot body assembly, which is equipped with an outer pot and an inner pot. The inner pot is located inside the outer pot, and a cooking space is formed inside the inner pot. The shell 210 of the lid assembly 200 can cover the outer pot, and a fastening structure is provided at the corresponding position of the outer pot or inner pot and the lid 220. By operating the operating structure 100, the lid 220 can be rotated relative to the shell 210, so that the lid 220 can be rotated to fasten to the outer pot or inner pot, and can be removed from the outer pot or inner pot. This eliminates the need for the user to manually twist the lid assembly 200, avoids the risk of burns, and makes operation convenient and effortless, improving the user experience.
