Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a pressure cooking device. Background Art

[0002] A pressure cooking appliance generally comprises a lid and a pot body. According to the assembly method of the lid and the pot body, the pressure cooking appliance can be divided into a one-piece type and a two-piece type. The lid and the pot body of the one-piece pressure cooking appliance are hinged so that the lid can be rotated around the hinge to open and close the lid. The lid of the two-piece pressure cooking appliance can be removed from the pot body to open and close the edge of the pot body.

[0003] For split-type pressure cooking utensils, after the user removes the pot lid from the pot body, they are faced with the problem of how to store the pot lid. If the pot lid is placed directly on the table, the condensed water on the pot lid will contaminate the table. Therefore, storing the pot lid after opening the lid becomes a more difficult problem for users during use. Therefore, some pressure cooking utensils are hinged with a swing arm on the pot body. The swing arm is located on one side of the pot lid, or extends from one side to the top of the pot lid. By providing a simple connection structure on the swing arm and the pot lid, a simple connection between the pot lid and the swing arm can be achieved. Therefore, when opening the lid, the pot lid can be lifted together with the swing arm, and the pot lid can be stored by leaning on the swing arm.

[0004] However, the connection structure between the swing arm and the pot cover is mostly a simple plug-in fit of a protrusion and a groove. Although it can achieve quick connection and disassembly, the connection stability is weak. On the one hand, when the user turns the pot cover to plug it into the protrusion and groove on the swing arm, the whole process is relatively smooth, and the user cannot know whether the protrusion and the groove are plugged in place, and then there is a problem that the two are not plugged in place, resulting in an unstable connection between the pot cover and the swing arm, and the pot cover is prone to shaking on the cantilever. On the other hand, there is no limit between the protrusion and the groove structure. When the pot cover shakes or is disturbed, it can still easily rotate in the direction of loosening, causing the protrusion to gradually slide out of the groove, causing the pot cover to fall off the swing arm, affecting the user experience. Utility Model Content

[0005] The utility model provides a pressure cooking device to solve the problem that the simple connection structure between a pot cover and a swing arm of a split pressure cooking device is unstable, causing the pot cover to easily shake relative to the swing arm or fall off the swing arm.

[0006] The technical solution adopted by the utility model is:

[0007] A pressure cooking device comprises a pot body and a pot cover which is removably placed on the pot body, the pot cover being rotatable to have a locked position and an unlocked position, the pressure cooking device also comprises a support cantilever which is hinged to the pot body and extends above the pot cover, the support cantilever and the pot cover being a detachable structure; the support cantilever is provided with a guide portion on one side of the pot cover, a matching portion is provided on the peripheral side of the pot cover, the guide portion is convexly provided with an elastic snap-fitting rib, the matching portion is provided with a fixing groove, when the pot cover is rotated to the unlocked position, the matching portion is plugged into and matched with the guide portion, and the elastic snap-fitting rib is snap-fitted with the fixing groove under the action of elastic force to fix the pot cover to the support cantilever.

[0008] The pressure cooking device of the present invention also has the following additional technical features:

[0009] One of the guide portion and the matching portion is a guide groove, and the other is a matching protrusion matching with the guide groove. One side of the guide groove has a transverse opening, and the matching protrusion can slide into the guide groove from the transverse opening.

[0010] The guiding portion is the guiding groove, the matching portion is the matching protrusion, the elastic snap-fitting rib protrudes from the guiding groove, the fixing groove is arranged on the matching protrusion, and a guiding transition surface is arranged on the side of the matching protrusion facing the elastic snap-fitting rib and / or on the side of the elastic snap-fitting rib facing the matching protrusion.

[0011] The pressure cooking device also includes a fixing member arranged on the supporting cantilever, an elastic member is arranged between the fixing member and the supporting cantilever, the fixing member can move under the elastic force of the elastic member, and at least a part of the fixing member protrudes toward the matching part to form the elastic clamping rib.

[0012] The support cantilever is provided with staggered reinforcing ribs, and adjacent reinforcing ribs form a limiting channel. The fixing piece is also provided with limiting ribs protruding toward the support cantilever, and the limiting ribs are located in the limiting channel and can slide along the limiting channel.

[0013] The pressure cooking device also includes a fastener, which is fixed to the supporting cantilever and clamps the fixing member with the supporting cantilever, the fixing member and / or the fastener are provided with positioning ribs, the elastic member is sleeved on the positioning ribs, and a reinforcement rib position is provided on the side of the fastener away from the fixing member corresponding to the elastic member.

[0014] The groove wall of the fixing groove has a contact arc surface, and the outer surface of the elastic clamping rib has a matching arc surface adapted to the contact arc surface.

[0015] The supporting cantilever has a positioning portion extending above the pot cover, and the supporting cantilever can be turned upside down around a hinge between the supporting cantilever and the pot body, so that the positioning portion has a horizontal position and a vertical position.

[0016] The guide portion is provided with a guide rib extending along the circumferential direction of the pot cover, and the matching portion is provided with a matching rib, and the matching rib is located outside the guide rib along the radial direction of the pot cover.

[0017] The supporting cantilever extends from one side of the pot cover at least to the central area of ​​the pot cover, and an operation panel is arranged on the top surface of the supporting cantilever.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. In the utility model, the pot cover can be rotated relative to the pot body to achieve switching between the locked position and the unlocked position, and can also be connected to or separated from the supporting cantilever. When the pot cover is rotated to the locked position, it is separated from the supporting cantilever, and the supporting cantilever can be rotated independently. When the pot cover is rotated to the unlocked position, it is fixed to the supporting cantilever, and the pot cover can be lifted up together with the supporting cantilever to complete the opening of the cover.

[0020] When the pot cover is rotated to the unlocking position, the matching portion on the circumference of the pot cover is plugged into and matched with the guide portion of the supporting cantilever to achieve preliminary fixation of the pot cover and the supporting cantilever. At the same time, the elastic snap-fit ​​rib at the guide portion is snap-fitted into and matched with the fixing groove of the matching portion to further fix the pot cover and the supporting cantilever, thereby achieving double fixation of the pot cover and the supporting cantilever, greatly improving the fixing stability, and alleviating the shaking of the pot cover relative to the supporting cantilever. In addition, the elastic snap-fit ​​rib is stopped by the fixing groove wall, so that it cannot be easily disengaged from the fixing groove, thereby being able to lock the pot cover in a state fixed to the supporting cantilever and unable to rotate at will. In addition, the elastic snap-fit ​​rib can move under the action of elastic force. When it is misaligned with the fixing groove, it is pushed and squeezed by the matching portion and is in a force storage state. When the pot cover is rotated into place, the elastic snap-fit ​​rib is aligned with the fixing groove, and then it rebounds into the fixing groove under the action of elastic force to complete the snap-fit. During this process, the elastic snap-fit ​​rib will collide with the inner wall of the fixing groove under the action of elastic force, thereby producing an obvious sound, so that the user can clearly know the snap-fit ​​state of the two, indicating that the pot cover has been rotated into place, thereby improving the user experience.

[0021] 2. As a preferred embodiment of the utility model, one of the guide portion and the matching portion is a guide groove, and the other is a matching protrusion matched with the guide groove, and one side of the guide groove has a transverse opening, and the matching protrusion can slide into the guide groove from the transverse opening. Through the matching of the guide groove and the matching protrusion, on the one hand, the matching portion can slide into the guide groove from the transverse opening as the pot cover rotates, or slide out from the guide groove, so that the matching direction of the two is consistent with the rotation direction of the pot cover, and the user can achieve two functions (locking or unlocking the pot cover and the pot body and loosening or plugging the guide portion and the matching portion) in one step, improving the convenience of operation, and the overall smoothness is good, and the user operation is more labor-saving. On the other hand, since the guide groove extends along the circumference of the pot cover, after the matching protrusion cooperates with the guide groove, it can also play a guiding role in the rotation of the pot cover, making the rotation of the pot cover more stable and reliable.

[0022] 3. As a preferred embodiment of the utility model, the pressure cooking device further comprises a fixing member arranged on the supporting cantilever, and at least a part of the fixing member protrudes toward the matching portion to form the elastic snap-fit ​​rib. The supporting cantilever is provided with staggered reinforcing ribs, and adjacent reinforcing ribs form a limiting channel. The fixing member is also provided with a limiting rib protruding toward the supporting cantilever, and the limiting rib is located in the limiting channel and can slide along the limiting channel. In this embodiment, in order to improve the structural strength of the supporting cantilever, a plurality of criss-cross reinforcing ribs are provided on the supporting cantilever, and the space surrounded by the intersection of the reinforcing ribs is cleverly utilized as a channel for limiting the movement of the fixing member. The fixing member is provided with a limiting rib extending into the limiting channel, and then the limiting rib is stopped by the reinforcing rib, so that the fixing member can only reciprocate along the extension direction of the limiting channel (i.e., the direction of approaching or moving away from the pot cover), so that the movement of the fixing member is more reliable, and the engagement of the elastic snap-fit ​​rib with the fixing groove is more stable.

[0023] 4. As a preferred embodiment of the present invention, the groove wall of the fixed groove has a contact arc surface, and the outer surface of the elastic snap-fitting rib has a matching arc surface adapted to the contact arc surface. During the rotation of the pot cover to the unlocked position, the matching portion squeezes the elastic snap-fitting rib, and the fixed groove gradually approaches the elastic snap-fitting rib from one side. The setting of the matching arc surface can reduce the contact area between it and the matching portion, thereby reducing the friction between the two and reducing the sticking feeling during the rotation of the pot cover. When the fixed groove and the elastic snap-fitting rib are aligned, the elastic snap-fitting rib extends into the fixed groove. At this time, the contact arc surface contacts the matching arc surface, and the two are in line contact or surface contact, which can increase the friction between the two and keep the pot cover in this position. When the pot cover rotates toward the locking position, the groove wall on one side of the fixing groove forms a pushing force on the elastic snap-in rib, causing the elastic snap-in rib to be deformed or moved under pressure, and then to escape from the fixing groove along the contact arc surface. During this process, the elastic snap-in rib moves along the contact arc surface, the friction between the two is small, and the movement is smoother, thereby improving the user's operating feel.

[0024] 5. As a preferred embodiment of the present invention, the guide portion is provided with a guide rib extending along the circumference of the pot cover, and the matching portion is provided with a matching rib, and the matching rib is located on the outside of the guide rib along the radial direction of the pot cover. The matching rib is located on the outside of the guide rib, and the cooperation of the two can further guide the rotation of the pot cover, so that the pot cover can rotate stably around its own center. At the same time, when the cantilever is flipped upward until the positioning portion is in the vertical position, the guide rib is located above the matching rib, and the supporting cantilever supports the pot cover upward, and at the same time, the guide rib limits it upward above the matching rib, thereby further improving the stability of the pot cover and the supporting cantilever fixing, and reducing the shaking of the pot cover.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0055] like Figures 1 to 17 As shown, a pressure cooking device comprises a pot body 1 and a pot cover 2 which is removably placed on the pot body 1, the pot cover 2 can be rotated to have a locked position and an unlocked position, the pressure cooking device also comprises a support cantilever 3 which is hinged to the pot body 1 and extends above the pot cover 2, the support cantilever 3 and the pot cover 2 are detachable structures; the support cantilever 3 is provided with a guide portion 31 on one side of the pot cover 2, the circumferential side of the pot cover 2 is provided with a matching portion 21, the guide portion 31 is convexly provided with an elastic snap-fitting rib 41, the matching portion 21 is provided with a fixing groove 212, when the pot cover 2 is rotated to the unlocked position, the matching portion 21 is plugged and matched with the guide portion 31, and the elastic snap-fitting rib 41 is snap-fitted with the fixing groove 212 under the action of elastic force to fix the pot cover 2 to the support cantilever 3.

[0056] In the utility model, the pot cover 2 can be rotated relative to the pot body 1 to achieve switching between the locked position and the unlocked position, and can also be connected to or separated from the support cantilever 3. When the pot cover 2 is rotated to the locked position, it is separated from the support cantilever 3, and the support cantilever 3 can be rotated independently. When the pot cover 2 is rotated to the unlocked position, it is fixed to the support cantilever 3, and the pot cover 2 can be lifted together through the support cantilever 3 to complete the opening of the cover.

[0057] At the same time, the detachable structure of the pot cover 2 and the supporting cantilever 3 provides the user with more options for opening and closing the lid. The pot cover 2 and the supporting cantilever 3 can be fixed and the two can be flipped open synchronously, or the supporting cantilever 3 can be flipped open first and then the pot cover 2 can be opened separately. When closing the lid, the pot cover 2 can be fixed to the supporting cantilever 3 first, and then the two can be flipped downwards synchronously to close the lid, or the pot cover 2 can be first covered on the pot body 1, and then the supporting cantilever 3 can be flipped downwards to above the pot cover 2.

[0058] When the pot cover 2 is rotated to the unlocking position, the matching portion 21 on the circumferential side of the pot cover 2 is plugged into and matched with the guide portion 31 of the supporting cantilever 3 to achieve preliminary fixation of the pot cover 2 and the supporting cantilever 3. At the same time, the elastic snap-fit ​​rib 41 at the guide portion 31 is snap-fitted with the fixing groove 212 of the matching portion 21 to further fix the pot cover 2 and the supporting cantilever 3, thereby achieving double fixation of the pot cover 2 and the supporting cantilever 3, greatly improving the fixing stability, and alleviating the shaking of the pot cover 2 relative to the supporting cantilever 3. In addition, the elastic snap-fit ​​rib 41 is stopped by the wall of the fixing groove 212, so that it cannot be easily disengaged from the fixing groove 212, thereby being able to lock the pot cover 2 in a fixed state with the supporting cantilever 3 and preventing it from rotating at will. In addition, the elastic snap-fit ​​rib 41 can move under the action of elastic force. When it is misaligned with the fixing groove 212, it is pushed and squeezed by the matching portion 21 and is in a force storage state. When the pot cover 2 is rotated into place, the elastic snap-fit ​​rib 41 is aligned with the fixing groove 212, and it rebounds into the fixing groove 212 under the action of elastic force to complete the snap connection. During this process, the elastic snap-fit ​​rib 41 will collide with the inner wall of the fixing groove 212 under the action of elastic force, thereby producing an obvious sound, so that the user can clearly know the snap connection state of the two, indicating that the pot cover 2 has been rotated into place, thereby improving the user experience.

[0059] Preferably, if Figure 1 , Figure 2 , Figure 4 As shown, the support cantilever 3 is also provided with a positioning protrusion 32 on the top of the pot cover 2, and a positioning groove 22 is correspondingly provided on the top of the pot cover 2. Through the cooperation of the positioning protrusion 32 and the positioning groove 22, the pot cover 2 is axially positioned at the top, so that the pot cover 2 is coaxial with the pot body 1. The guide portion 31 and the matching portion 21 cooperate on one side of the pot cover 2 to play a side positioning role for the pot cover 2, so that the pot cover 2 and the pot body 1 are circumferentially positioned. Specifically, the pot cover 2 is provided with a cover tooth, and the pot body 1 is provided with a pot tooth. When closing the cover, it is necessary to ensure that the cover tooth and the pot tooth are misaligned up and down. After closing the cover, the pot cover 2 is in the unlocking position, and then the pot cover 2 is rotated to make the pot tooth correspond to the cover tooth up and down to complete the locking. At this time, the pot cover 2 is in the locking position. The top positioning and the side positioning ensure that when the lid is closed, the pot cover 2 is coaxial with the pot body 1, and the lid teeth and the pot teeth are in a misaligned state, so that the placement of the pot cover 2 is simpler and more convenient, and the user experience is improved.

[0060] Of course, the positioning groove 22 can also be provided on the supporting cantilever 3, and the positioning protrusion 32 can be provided on the top of the pot cover 2 to also achieve top positioning, which is not limited here.

[0061] As a preferred embodiment of the present invention, Figure 2 , Figure 5 As shown, one of the guide portion 31 and the matching portion 21 is a guide groove 311, and the other is a matching protrusion 211 matching with the guide groove 311. One side of the guide groove 311 has a transverse opening, and the matching protrusion 211 can slide into the guide groove 311 from the transverse opening.

[0062] Through the cooperation of the guide groove 311 and the matching protrusion 211, on the one hand, the matching portion 21 can slide into the guide groove 311 from the transverse opening as the pot cover 2 rotates, or slide out from the guide groove 311, so that the matching direction of the two is consistent with the rotation direction of the pot cover 2, and the user can achieve two functions (locking or unlocking the pot cover 2 and the pot body 1 and loosening or plugging the guide portion 31 and the matching portion 21) in one step, thereby improving the convenience of operation, and the overall smoothness is good, and the user operation is more labor-saving. On the other hand, since the guide groove 311 extends along the circumferential direction of the pot cover 2, after the matching protrusion 211 cooperates with the guide groove 311, it can also guide the rotation of the pot cover 2, making the rotation of the pot cover 2 more stable and reliable.

[0063] Taking the guide portion 31 as the guide groove 311 and the matching portion 21 as the matching protrusion 211 as an example, Figure 2 , Figures 12 to 15 As shown, the guide groove 311 is located at the support cantilever 3, the elastic snap-fit ​​rib 41 is convexly arranged in the guide groove 311, the matching protrusion 211 is located on the peripheral side of the pot cover 2 and protrudes laterally, and the fixing groove 212 is arranged on the surface of the matching protrusion 211. When the pot cover 2 rotates to the unlocking position, the matching protrusion 211 gradually slides into the guide groove 311 from the transverse opening, and gradually contacts with the elastic snap-fit ​​rib 41. The elastic snap-fit ​​rib 41 moves or deforms under the pushing action of the matching protrusion 211, and begins to accumulate force. When the fixing groove 212 moves to the position aligned with the elastic snap-fit ​​rib 41, the elastic snap-fit ​​rib 41 loses extrusion, and thus moves quickly toward the matching protrusion 211 under the action of elastic force, completes the snap-fit ​​with the fixing groove 212, and collides with the groove wall of the fixing groove 212 to make a sound, so as to form a prompt to the user that the pot cover 2 is rotated to the right position.

[0064] In another embodiment, the guide portion 31 is a mating protrusion protruding from the supporting cantilever 3, the mating portion 21 is a guide groove located on the peripheral side of the pot cover 2, the elastic snap-in rib 41 is protruding from the mating protrusion, and a partial area of ​​the guide groove wall is further recessed to form the fixing groove, which can also achieve the snap connection between the two, which will not be elaborated here.

[0065] Furthermore, if Figure 5 , Figures 12 to 15 As shown, the guide portion 31 is the guide groove 311, the matching portion 21 is the matching protrusion 211, the elastic snap-fit ​​rib 41 protrudes from the guide groove 311, the fixing groove 212 is arranged on the matching protrusion 211, and a guide transition surface 213 is arranged on the side of the matching protrusion 211 facing the elastic snap-fit ​​rib 41 and / or the side of the elastic snap-fit ​​rib 41 facing the matching protrusion 211.

[0066] When one side of the mating protrusion 211 contacts and slides relatively with the elastic snap-fit ​​rib 41, the elastic snap-fit ​​rib 41 moves along the guide transition surface 213 on the surface of the mating protrusion 211, which can reduce the friction between the elastic snap-fit ​​rib 41 and the surface of the mating protrusion 211 and improve the smoothness of relative movement.

[0067] Preferably, the surface of the mating protrusion 211 and the surface of the elastic snap-fit ​​rib 41 are both provided with the guide transition surface 213, and the guide transition surface 213 on the surface of the mating protrusion 211 is a slope structure, and the guide transition surface 213 on the surface of the elastic snap-fit ​​rib 41 is an arc surface, and the two are in contact and tangent, at which time the elastic snap-fit ​​rib 41 is subjected to pressure perpendicular to the tangent surface, and the elastic member 5 is compressed. So that the two are in line contact after contact, so as to reduce the contact area and reduce the effect of jamming. Of course, the guide transition surface 213 of the mating protrusion 211 and the elastic snap-fit ​​rib 41 can also be the same shape, or other different shapes, which are not limited here.

[0068] It should be noted that the present invention does not limit the working mode of the elastic clamping rib 41, which can be one of the following embodiments:

[0069] Embodiment 1: In this embodiment, the elastic snap-fit ​​rib 41 is a structure made of elastic material, so that the elastic snap-fit ​​rib 41 can be elastically deformed when squeezed, and can rebound and reset under the action of its own elastic force when the squeezing force is lost. For example, the elastic snap-fit ​​rib 41 is a silicone part, or an elastic metal part, etc.

[0070] Implementation method 2: In this implementation method, Figure 1 , Figure 6 , Fig.13 As shown, the pressure cooking appliance also includes a fixing member 4 arranged on the supporting cantilever 3, and an elastic member 5 is arranged between the fixing member 4 and the supporting cantilever 3. The fixing member 4 can move under the elastic force of the elastic member 5, and at least a part of the fixing member 4 protrudes toward the matching portion 21 to form the elastic snap-in rib 41.

[0071] In this embodiment, the elastic snap-fit ​​rib 41 itself is inelastic, and the elastic member 5 is provided at the connection position thereof, so that the elastic snap-fit ​​rib 41 is pushed to move by the elastic member 5. Preferably, the elastic member 5 is a spring.

[0072] Specifically, Figure 6 As shown, the fixing member 4 is partially protruded to form the elastic snap-fit ​​rib 41. At the same time, there are reinforcing arcs 43 between the two sides of the elastic snap-fit ​​rib 41 and the fixing member 4 body to improve the strength of the elastic snap-fit ​​rib 41 and avoid the elastic snap-fit ​​rib 41 from being broken due to long-term shear force.

[0073] Furthermore, if Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, the support cantilever 3 is provided with staggered reinforcing ribs 35, and adjacent reinforcing ribs 35 form a limiting channel 351. The fixing member 4 is also provided with limiting ribs 44 protruding toward the support cantilever 3, and the limiting ribs 44 are located in the limiting channel 351 and can slide along the limiting channel 351.

[0074] In this embodiment, in order to improve the structural strength of the support cantilever 3, a plurality of criss-crossing reinforcing ribs 35 are provided on the support cantilever 3, and the space enclosed by the intersection of the reinforcing ribs 35 is cleverly utilized as a channel for limiting the movement of the fixing member 4. The fixing member 4 is provided with a limiting rib 44 extending into the limiting channel 351, and then the limiting rib 44 is stopped by the reinforcing rib 35, so that the fixing member 4 can only reciprocate along the extension direction of the limiting channel 351 (i.e., the direction of approaching or moving away from the pot cover 2), so that the movement of the fixing member 4 is more reliable, and the engagement of the elastic snap-in rib 41 with the fixing groove 212 is also more stable.

[0075] Specifically, Figure 6 , Figure 7 As shown, the limiting rib 44 has a contact rib 441 protruding upward and downward and / or left and right, and the surface of the contact rib 441 is an arc surface, which contacts the plane of the reinforcing rib 35 through the arc surface, so that the contact rib 441 and the reinforcing rib 35 are in line contact, thereby reducing the friction resistance between the two and improving the smoothness of the movement of the fixing member 4.

[0076] Preferably, if Figure 1 , Figure 7 , Figure 8 , Fig. 9 , Fig.13As shown, the pressure cooking appliance also includes a fastener 6, which is fixed to the supporting cantilever 3 and clamps the fixing member 4 with the supporting cantilever 3, the fixing member 4 and / or the fastener 6 are provided with a positioning rib 61, the elastic member 5 is sleeved on the positioning rib 61, and the side of the fastener 6 facing away from the fixing member 4 is provided with a reinforcement rib position 62 corresponding to the elastic member 5.

[0077] The fastener 6 is fixed to the support cantilever 3, and the fixing member 4 is installed between the two. One end of the elastic member 5 acts on the fixing member 4, and the other end acts on the fastener 6. The positioning rib 61 inside the elastic member 5 can limit the deformation of the elastic member 5, so that it can only deform along the axial direction without offset, thereby ensuring the stability of the elastic action and improving the service life of the elastic member 5. Preferably, as Fig.11 As shown, both the fastener 6 and the fixing member 4 are provided with the positioning rib 61 .

[0078] like Fig. 9 As shown, a reinforcing rib 62 is provided on the other side of the fastener 6 corresponding to the elastic member 5 to increase the strength of the fastener 6 at this location and prevent the fastener 6 from being deformed under the action of the elastic member 5 .

[0079] Preferably, if Figure 8 , Fig. 9 As shown, the fastener 6 is provided with a fixing hole 63, so as to fix the fastener 6 to the supporting cantilever 3 by means of screws and other components, and the fixing holes 63 are multiple and evenly spaced along the circumference of the elastic member 5, so as to form a uniform supporting force around the elastic member 5. Of course, the fastener 6 can also be fixed to the supporting cantilever 3 by other means, such as clamping fixation, etc., which is not limited here.

[0080] In a preferred embodiment, Figure 6 , Fig.13 , Fig.15 As shown, the groove wall of the fixing groove 212 has a contact arc surface 215 , and the outer surface of the elastic clamping rib 41 has a matching arc surface 42 adapted to the contact arc surface 215 .

[0081] It should be noted that the present embodiment does not limit the location of the contact arc surface 215. In one embodiment, the groove wall of the fixing groove 212 constitutes the contact arc surface 215 as a whole, and the outer surface of the elastic snap-fit ​​rib 41 constitutes the matching arc surface 42 as a whole. During the rotation of the pot cover 2 to the unlocked position, the matching portion 21 squeezes the elastic snap-fit ​​rib 41, and the fixing groove 212 gradually approaches the elastic snap-fit ​​rib 41 from one side. The setting of the matching arc surface 42 can reduce the contact area between it and the matching portion 21, thereby reducing the friction between the two and reducing the sticking feeling during the rotation of the pot cover 2. When the fixing groove 212 is aligned with the elastic snap-fit ​​rib 41, the elastic snap-fit ​​rib 41 extends into the fixing groove 212. At this time, the contact arc surface 215 contacts the matching arc surface 42, and the two are in line contact or surface contact, which can increase the friction between the two and keep the pot cover 2 in this position. When the pot cover 2 rotates toward the locking position, the groove wall on one side of the fixing groove 212 forms a pushing force on the elastic snap-fit ​​rib 41, causing the elastic snap-fit ​​rib 41 to be deformed or moved under pressure, and then to escape from the fixing groove 212 along the contact arc surface 215. During this process, the elastic snap-fit ​​rib 41 moves along the contact arc surface 215, the friction between the two is small, and the movement is smoother, thereby improving the user's operating feel.

[0082] In another embodiment, if Fig.13 , Fig.15 As shown, the contact arc surface 215 is arranged at the notch positions on both sides of the fixing groove 212, and the elastic snap-fitting rib 41 is provided with the matching arc surface 42 at the edges on both sides, and the bottom of the fixing groove 212 and the top of the elastic snap-fitting rib 41 are both planes, so that when the two are matched, the collision is more intense, thereby being able to produce a clear sound. When the elastic snap-fitting rib 41 moves to the mouth of the fixing groove 212, the contact arc surface 215 is tangent to the matching arc surface 42, and the elastic snap-fitting rib 41 is compressed and retreated by pressure during movement, ensuring that the pot cover 2 moves smoothly.

[0083] Preferably, if Figure 2 , Fig.10 , Fig.16 As shown, the support cantilever 3 has a positioning portion 34 extending above the pot cover 2, and the support cantilever 3 can be turned up and down around the hinge between it and the pot body 1 so that the positioning portion 34 has a horizontal position and a vertical position.

[0084] It should be noted that the horizontal position and the vertical position here only represent two positions of the positioning portion 34, that is, the positioning portion 34 may not be completely horizontal in the horizontal position, but may be inclined to the horizontal plane. In the vertical position, the positioning portion 34 may not be 90° with the horizontal plane, but may be at an angle with the vertical plane.

[0085] It should be noted that the present invention does not limit the structure of the supporting cantilever 3. Specifically, the supporting cantilever 3 further includes a supporting portion 33 located on one side of the pot cover 2. Figure 1 , Fig.16 As shown, the support cantilever 3 can be hinged to the pot body 1 through the support portion 33, so that the support cantilever 3 can be turned up and down around the hinge as a whole.

[0086] The guide portion 31 is a guide groove 311, and the matching portion 21 is a matching protrusion 211. In the horizontal position, the guide groove 311 has an opening on the side facing the pot cover 2, and the opening is horizontally facing the pot cover 2. When the support cantilever 3 rotates to the vertical position, the opening faces upward. Fig.17 As shown, under the action of gravity, the pot cover 2 presses the elastic snap-fit ​​rib 41 downward, so that the elastic member 5 is compressed, and the contact arc surface 215 in the fixing groove 212 is staggered with the matching arc surface 42 of the elastic snap-fit ​​rib 41, thereby fixing the pot cover 2.

[0087] Furthermore, if Fig.11 , Fig.17 As shown, the guide portion 31 is provided with a guide rib 312 extending along the circumferential direction of the pot cover 2 , and the matching portion 21 is provided with a matching rib 214 , and the matching rib 214 is located outside the guide rib 312 along the radial direction of the pot cover 2 .

[0088] The matching rib 214 is located outside the guide rib 312, and the cooperation between the two can further guide the rotation of the pot cover 2, so that the pot cover 2 can rotate stably around its own center. Fig.17 As shown, at this time, the guide rib 312 is located above the matching rib 214, and the support cantilever 3 supports the pot cover 2 upward. At the same time, the guide rib 312 limits the matching rib 214 upward, thereby further improving the stability of the fixation between the pot cover 2 and the support cantilever 3 and reducing the shaking of the pot cover 2.

[0089] Specifically, the matching portion 21 is a matching protrusion 211 , the guiding portion 31 is a guiding groove 311 , the edge of the matching protrusion 211 is bent downward to form the matching rib 214 , and the bottom wall of the guiding groove 311 is provided with the guiding rib 312 .

[0090] In other embodiments, the support portion 33 may also be fixedly connected to the pot body 1, and the positioning portion 34 is hinged to the support portion 33, so that the positioning portion 34 is indirectly hinged to the pot body 1, so that the positioning portion 34 can be flipped up and down independently.

[0091] Preferably, if Figure 1 , Fig.10 As shown, the supporting arm 3 extends from one side of the pot cover 2 at least to the central area of ​​the pot cover 2, and an operation panel is provided on the top surface of the supporting arm 3.

[0092] Since the support cantilever 3 is hinged to the pot body 1, the electrical connection between the pot body 1 and the support cantilever 3 can be realized by routing the wires through the hinge. The operation panel is located above the support cantilever 3 and is arranged upward, so the user can directly observe the display information on the operation panel from above and operate the operation panel without bending over, thereby reducing the difficulty of operation and improving the user experience.

[0093] The supporting cantilever 3 extends at least to the central area of ​​the pot cover 2, thereby leaving a larger installation space for the operation panel, so that the area of ​​the operation panel can be increased, so that it can display cooking information in more detail, and the corresponding operation buttons can also be increased, thereby giving the cooking appliance more functions, enriching user choices, and improving the user experience.

[0094] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0095] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0096] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
