Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a cooking utensil. Background Art

[0002] Cooking appliances usually help people cook food more conveniently. For example, rice cookers, induction cookers, electric ovens, etc. can help people cook rice, soup, barbecue, etc. They can also have multiple functions and cook different kinds of food. For example, a multi-function rice cooker can cook rice, steam vegetables, stew soup, etc., which increases the diversity and convenience of cooking.

[0003] Cooking utensils in related art generally include a pot body and a lid. To ensure a stable connection between the lid and the pot body, the lid is typically locked to the pot body through a locking mechanism. Specifically, the lid body is provided with a cover tooth, and the pot body is provided with a pot tooth. The cover tooth and pot tooth are locked by screwing, moving, or flipping.

[0004] Specifically, the cover body is provided with a handle for driving the cover teeth to rotate, move or flip, and a transmission member connected between the handle and the cover teeth. The provision of the handle makes the structure of the cover body complicated, which increases the manufacturing cost of the cover body. Utility Model Content

[0005] The main purpose of the utility model is to provide a cooking utensil to solve the problem of complex structure of the cover in the related art.

[0006] In order to achieve the above-mentioned object, the utility model provides a cooking utensil, comprising: a pot body, on which pot teeth are provided; a cover body, which is provided on the pot body, the cover body comprising a cover body main body and a first locking mechanism provided on the cover body main body, the first locking mechanism being movably provided relative to the cover body main body, and having a first unlocking position separated from the pot teeth and a first locking position engaged with the pot teeth; a first driving structure, which is movably provided on the pot body; a lower transmission member, which is rotatably provided on the pot body, and the lower transmission member is driven and matched with the first driving structure; a second driving structure, which is rotatably provided on the cover body; an upper transmission member, which is rotatably provided on the cover body, and the upper transmission member is driven and matched with the first driving structure The two drive structures drive cooperation; the plug-in structure is arranged between the lower transmission member and the upper transmission member, wherein the first drive structure drives the lower transmission member to rotate when it moves, and drives the upper transmission member to rotate through the plug-in structure, so as to drive the second drive structure to drive the first locking mechanism to switch between the first unlocking position and the first locking position; the second locking mechanism is movably arranged on the pot body, and has a second locking position for locking the cover body on the pot body and a second unlocking position for unlocking the cover body so that the cover body can be opened from the pot body; the unlocking member is movably arranged at the first drive structure, and the unlocking member drives the second locking mechanism to switch from the second locking position to the second unlocking position.

[0007] When using the technical solution of the present invention, when a user uses the cooking utensil to cook food, they first lock the lid to the pot body using the second locking mechanism. At this point, the user moves the first drive structure to rotate the lower transmission member, and the upper transmission member rotates via the plug-in structure, which drives the second drive structure to drive the first locking mechanism from the first unlocked position to the first locked position. The food can then be cooked inside the cooking utensil. When cooking is finished or the lid needs to be opened, the user moves the first drive structure, which sequentially drives the first locking mechanism from the first locked position to the first unlocked position via the lower transmission member, the plug-in structure, the upper transmission member, and the second drive structure. The user then moves the unlocking member, which drives the second locking mechanism from the second locked position to the second unlocked position. At this point, the lid can be opened from the pot body. Because the first drive structure of the present invention is movably disposed on the pot body, there is no need for a handle on the lid body, simplifying the structure of the lid body and helping to reduce the manufacturing cost of the lid body. Therefore, the technical solution of the present invention effectively solves the problem of complex lid structure in the related art. Moreover, since the unlocking member is movably arranged at the first driving structure, the distance between the unlocking member and the first driving structure is relatively close. After driving the first driving structure, the user does not need to change position to operate the unlocking member to open the cover, which improves the user's operating convenience and brings the user a better product experience.

[0008] Furthermore, the first driving structure has a first driving position and a second driving position when it moves. When the first driving structure is in the first driving position, the corresponding first locking mechanism is in the first unlocking position, and when the first driving structure is in the second driving position, the corresponding first locking mechanism is in the first locking position; the cooking utensil also includes a first locking structure movably arranged on the pot body, the first locking structure having a first avoidance position for avoiding the movement of the first driving structure and a first locking position for locking the first driving structure in the first driving position; when the second locking mechanism is in the second locking position, and the cover body pushes the first locking structure to move and is in the first avoidance position, the first driving structure switches between the first driving position and the second driving position; when the second locking mechanism is in the second unlocking position and the first driving structure is in the first driving position, the cover body avoids the first locking structure, causing the first locking structure to move and be in the first locking position. Since the above-mentioned first locking structure locks the first driving structure in the first driving position, when the cover body is placed on the pot body again, the first driving structure or the lower transmission member or the plug-in structure will not interfere with the cover body, and the plug-in structure between the lower transmission member and the upper transmission member can be plugged in smoothly, which facilitates the lower transmission member and the upper transmission member to be combined together. Then, when the second locking mechanism is in the second locking position, when the first driving structure is moved, it can drive the lower transmission member to rotate, so as to achieve the purpose of driving the upper transmission member to rotate through the plug-in structure.

[0009] Furthermore, the first locking structure includes a lock hook portion and a first protrusion provided on the lock hook portion. The first driving structure is provided with a lock column that cooperates with the lock hook portion. When the cover body pushes the first protrusion to move so that the first locking structure is in the first avoidance position, the lock column can disengage from the lock hook portion. When the cover body moves to avoid the first protrusion, the lock hook portion hooks the lock column, and the first locking structure is in the first locked position. In the movement direction of the first driving structure, the lock column is constrained by the lock hook portion, which facilitates the first locking structure to remain in the first locked position, thereby improving the locking reliability of the first locking structure.

[0010] Furthermore, the cooking utensil further includes a first anti-slip member for mounting the first locking structure on the pot body, and a first elastic return member disposed between the first anti-slip member and the first locking structure, the first elastic return member applying a first elastic force to the first locking structure so as to cause the first locking structure to be subjected to a force moving from the first avoidance position to the first locking position. When the lid is opened from the pot body, the first locking structure loses the downward pressure of the lid, and the first locking structure can move from the first avoidance position to the first locking position under the first elastic force of the first elastic return member.

[0011] Furthermore, the second drive structure has a third drive position and a fourth drive position when it rotates. When the second drive structure is in the third drive position, the corresponding first locking mechanism is in the first unlocked position, and when the second drive structure is in the fourth drive position, the corresponding first locking mechanism is in the first locked position; the cooking utensil also includes a second locking structure movably arranged on the cover body, the second locking structure having a second avoidance position for avoiding the movement of the second drive structure and a second locking position for locking the second drive structure in the third drive position; when the second locking mechanism is in the second locking position, and the pot body pushes the second locking structure to move and is in the second avoidance position, the second drive structure switches between the third drive position and the fourth drive position; when the second locking mechanism is in the second unlocked position and the second drive structure is in the third drive position, the pot body avoids the second locking structure, causing the second locking structure to move and be in the second locking position. Since the above-mentioned second locking structure locks the second drive structure in the third drive position, when the cover body is placed on the pot body again, the second drive structure or the upper transmission member or the plug-in structure will not interfere with the pot body, and the plug-in structure between the lower transmission member and the upper transmission member can be plugged in smoothly, which facilitates the lower transmission member and the upper transmission member to be combined together. Then, when the second locking mechanism is in the second locking position, when the first drive structure is moved, it can drive the lower transmission member to rotate, so as to achieve the purpose of driving the upper transmission member to rotate through the plug-in structure.

[0012] Furthermore, the second locking structure includes a hook portion and a second protrusion disposed on the hook portion. The second driving structure is provided with a locking hole that cooperates with the hook portion. When the pot body pushes the second protrusion to move the second locking structure to the second avoidance position, the hook portion disengages the locking hole. When the pot body moves to avoid the second protrusion, the hook portion hooks into the locking hole, and the second locking structure is now in the second locked position. In the rotational direction of the second driving structure, the locking hole is restricted by the hook portion, facilitating the second locking structure to remain in the second locked position, thereby improving the locking reliability of the second locking structure.

[0013] Furthermore, the cooking utensil also includes a second anti-slip component for installing the second locking structure on the cover body, and the cooking utensil also includes a second elastic return component arranged between the second anti-slip component and the second locking structure, and the second elastic return component applies a second elastic force to the second locking structure so that the second locking structure is subjected to a force moving from the second avoidance position to the second locking position. When the cover is opened from the pot body, the second locking structure loses the upper top of the pot body, and the second locking structure can move from the second avoidance position to the second locking position under the action of the second elastic force of the second elastic return component.

[0014] Furthermore, the first drive structure includes a lower drive body movably mounted on the pot body, a first tooth portion mounted on the lower drive body, and a lower transmission member includes a second tooth portion that engages with the first tooth portion; and / or the second drive structure includes an upper drive body rotatably mounted on the lid body, a third tooth portion mounted on the upper drive body, and an upper transmission member includes a fourth tooth portion that engages with the third tooth portion. This tooth arrangement ensures a smooth transmission process, a stable structure, a simple structure, and low cost and ease of production.

[0015] Furthermore, the plug-in structure includes a socket and an insert block that can be inserted into the socket, one of the socket and the insert block is provided on the lower transmission member, and the other of the socket and the insert block is provided on the upper transmission member. The above-mentioned plug-in connection between the socket and the insert block is simple, low-cost and easy to produce.

[0016] Furthermore, the cooking appliance includes an operating member movably mounted on the pot body. When the operating member is moved, it drives the first drive structure to move. The unlocking member is disposed within the operating member. The unlocking member and the operating member are located in the same location. After the user activates the first drive structure with the operating member, they can operate the unlocking member to open the lid without having to move to another location. This improves user convenience and provides a better product experience.

[0017] Furthermore, an arc-shaped hole is provided on the main body of the cover, a drive slot is provided at a position corresponding to the arc-shaped hole of the second drive structure, and a drive post is provided above the first locking mechanism and is inserted through the arc-shaped hole and the drive slot. When the upper transmission member rotates, the second drive structure is driven to swing, and the second drive structure drives the first locking mechanism to switch between the first unlocked position and the first locked position via the drive post. The provision of the above-mentioned arc-shaped hole can guide the movement of the drive post, facilitating the smooth switching of the first locking mechanism between the first unlocked position and the first locked position. The provision of the above-mentioned drive slot facilitates the second drive structure to directly drive the drive post. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] like Figures 1 to 6 As shown, the present application provides a cooking appliance. The embodiment of the cooking appliance includes: a pot body 10, a lid body 20, a first drive structure 30, a lower transmission member 41, a second drive structure 50, an upper transmission member 43, a plug-in structure 45, a second locking mechanism 60, and an unlocking member 63. The pot body 10 is provided with pot teeth 141. The lid body 20 is disposed on the pot body 10. The lid body 20 includes a lid body 21 and a first locking mechanism 22 disposed on the lid body 21. The first locking mechanism 22 is movably disposed relative to the lid body 21 and has a first unlocked position separated from the pot teeth 141 and a first locked position engaged with the pot teeth 141. The first drive structure 30 is movably disposed on the pot body 10. The lower transmission member 41 is rotatably disposed on the pot body 10 and is driven in conjunction with the first drive structure 30. The second drive structure 50 is rotatably disposed on the lid body 20. The upper transmission member 43 is rotatably disposed on the cover body 20, and the upper transmission member 43 is driven in conjunction with the second drive structure 50. The plug-in structure 45 is disposed between the lower transmission member 41 and the upper transmission member 43, wherein when the first drive structure 30 moves, the lower transmission member 41 is driven to rotate, and the upper transmission member 43 is driven to rotate through the plug-in structure 45, thereby driving the second drive structure 50 to drive the first locking mechanism 22 to switch between the first unlocked position and the first locked position. The second locking mechanism 60 is movably disposed on the pot body 10, and has a second locked position for locking the cover body 20 on the pot body 10 and a second unlocked position for unlocking the cover body 20 so that the cover body 20 can be opened from the pot body 10. The unlocking member 63 is movably disposed on the first drive structure 30, and the unlocking member 63 drives the second locking mechanism 60 to switch from the second locked position to the second unlocked position.

[0049] Using the technical solution of this embodiment, when a user uses the cooking utensil to cook food, they first lock the lid 20 to the pot body 10 using the second locking mechanism 60. At this point, the user moves the first drive structure 30 to rotate the lower transmission member 41, and then rotates the upper transmission member 43 via the plug-in structure 45, thereby driving the second drive structure 50 to drive the first locking mechanism 22 from the first unlocked position to the first locked position. The food can then be cooked in the cooking utensil. When cooking is finished or the lid needs to be opened, the user moves the first drive structure 30, and sequentially drives the first locking mechanism 22 from the first locked position to the first unlocked position via the lower transmission member 41, the plug-in structure 45, the upper transmission member 43, and the second drive structure 50. The user then moves the unlocking member 63, which drives the second locking mechanism 60 from the second locked position to the second unlocked position. At this point, the lid 20 can be opened from the pot body 10. Since the first drive structure 30 of the present application is movably provided on the pot body 10, there is no need to set a handle on the lid body 20, which simplifies the structure of the lid body 20 and helps reduce the manufacturing cost of the lid body 20. Therefore, the technical solution of this embodiment effectively solves the problem of complex structure on the lid body in the related art. In addition, since the unlocking member 63 is movably provided at the first drive structure 30, the distance between the unlocking member 63 and the first drive structure 30 is relatively close. After driving the first drive structure 30, the user does not need to change positions to operate the unlocking member 63 to open the lid, which improves the user's operational convenience and brings a better product experience to the user. In addition, since there is no need to set a handle on the top of the lid body, the space on the top of the lid body is freed up, and a larger light board interaction interface can be set, or the position of the light board interaction interface can be adjusted, thereby enhancing the user experience of the light board interaction interface.

[0050] It should be noted that the pot body includes an outer pot and an inner pot arranged in the outer pot, and the pot teeth are arranged on the outer pot or the inner pot, wherein the outer pot includes an outer shell and a heat-insulating cover arranged in the outer shell, and the pot teeth are arranged on the heat-insulating cover, or the outer pot includes an outer shell, a middle plate arranged on the top of the outer shell and a pressure ring arranged above the middle plate, and the pot teeth are arranged on the pressure ring.

[0051] It should be noted that the first locking mechanism includes a locking ring or locking cover rotatably mounted on the cover body, the locking ring or locking cover having a cover tooth that engages or disengages with the pot teeth. Of course, in other embodiments, the first locking mechanism includes a caliper structure that is movable in the radial direction of the cover body, the caliper structure having a cover tooth that engages or disengages with the pot teeth, or the first locking mechanism includes a flap having a cover tooth that is flipped and mounted on the cover body, engaging or disengaging with the pot teeth. When the cover tooth engages with the pot teeth, the first locking mechanism is in a first locked position; when the cover tooth disengages from the pot teeth, the first locking mechanism is in a first unlocked position.

[0052] The pot teeth of the present application can be a pot edge, a convex edge or an outward turning edge.

[0053] It should be noted that the unlocking member 63 is provided at the first driving structure 30 , which means that the unlocking member 63 is provided on the left side, right side, top side, bottom side, or middle side of the first driving structure 30 .

[0054] like Figure 2 、 Figure 4 、 Figures 6 to 9 As shown, the first driving structure 30 has a first driving position and a second driving position when it moves. When the first driving structure 30 is in the first driving position, the corresponding first locking mechanism 22 is in the first unlocking position. When the first driving structure 30 is in the second driving position, the corresponding first locking mechanism 22 is in the first locking position.

[0055] In this application, the inventors found that the cover can be placed on the pot only when the first drive structure 30 is in the first drive position. If the first drive structure 30 is in the second drive position or other positions, the first drive structure 30 or the lower transmission member 41 or the plug-in structure 45 will interfere with the cover, resulting in the cover being unable to be placed on the pot. In order to solve this problem, Figure 2 、 Figure 4 、 Figures 6 to 9 、 Figure 13 and Figure 14 As shown, an embodiment of the cooking utensil also includes a first locking structure 70 movably provided on the pot body 10, and the first locking structure 70 has a first avoidance position for avoiding the movement of the first driving structure 30 and a first locking position for locking the first driving structure 30 in the first driving position; when the second locking mechanism 60 is in the second locking position and the cover body 20 pushes the first locking structure 70 to move and is in the first avoidance position, the first driving structure 30 switches between the first driving position and the second driving position; when the second locking mechanism 60 is in the second unlocking position and the first driving structure 30 is in the first driving position, the cover body 20 avoids the first locking structure 70, causing the first locking structure 70 to move and be in the first locking position. In this way, since the first locking structure 70 locks the first driving structure 30 in the first driving position, when the cover body is placed on the pot body again, the first driving structure 30 or the lower transmission member 41 or the plug-in structure 45 will not interfere with the cover body, and the plug-in structure 45 between the lower transmission member 41 and the upper transmission member 43 can be smoothly plugged in, so that the lower transmission member 41 and the upper transmission member 43 are combined together. Then, when the second locking mechanism 60 is in the second locking position, when the first driving structure 30 is moved, it can drive the lower transmission member 41 to rotate, so as to achieve the purpose of driving the upper transmission member 43 to rotate through the plug-in structure 45.

[0056] In this embodiment, the first locking structure 70 is movably provided along the up-down direction of the pot body. Of course, in embodiments not shown in the figures, the first locking structure can be movably provided along the left-right direction or the front-back direction of the pot body.

[0057] like Figure 2 、 Figure 4 、 Figures 6 to 9 、 Figure 13 and Figure 14 As shown, the first locking structure 70 includes a lock hook portion 71 and a first protrusion 72 disposed on the lock hook portion 71. The first driving structure 30 is provided with a lock post 33 that cooperates with the lock hook portion 71. When the cover 20 presses down on the first protrusion 72 and pushes the first protrusion 72 downward to place the first locking structure 70 in the first avoidance position, the lock post 33 can disengage from the lock hook portion 71. When the cover is placed on the pot body, since the first protrusion 72 protrudes upward from the top of the pot body, the cover 20 can first directly contact the top of the first protrusion 72 and push the first protrusion 72 downward to move the first protrusion 72 downward. When the second locking mechanism 60 is in the second locked position and the first locking structure 70 is in the first avoidance position, the lock post 33 just corresponds to the hook opening of the lock hook portion 71. At this time, when the user operates the first driving structure 30, the first driving structure 30 smoothly disengages from the lock hook portion 71 and can switch between the first driving position and the second driving position.

[0058] like Figure 2 、 Figure 4 、 Figures 6 to 9 、 Figure 13 and Figure 14 As shown, when the cover 20 moves upward to avoid the first protrusion 72, the lock hook 71 hooks the lock column 33, and the first locking structure 70 is in the first locked position. When the second locking mechanism 60 is in the second unlocked position, the cover can be opened from the pot body, the cover 20 no longer presses down the first protrusion 72, the cover 20 avoids the first protrusion 72, the first protrusion 72 can move upward, and the first protrusion 72 reaches a position protruding from the top of the pot body again. The lock hook 71 hooks the lock column 33. In the left and right movement direction of the first driving structure 30, the lock column 33 is restricted in the lock hook 71, which facilitates the first locking structure 70 to remain in the first locked position, thereby improving the reliability of the locking of the first locking structure 70.

[0059] It should be noted that when the first locking structure 70 is in the first locking position, the first protrusion 72 protrudes from the top of the pot body. When the first locking structure 70 is in the first avoidance position, the first protrusion 72 is lower than or flush with the top of the pot body. Specifically, the top of the pot body is provided with a first avoidance hole 132 for the first protrusion 72 to protrude from the top of the pot body.

[0060] like Figure 2 、 Figure 4 、 Figures 6 to 10 As shown, the cooking utensil also includes a first anti-slip member 73 for mounting the first locking structure 70 on the pot body 10. In this way, the provision of the first anti-slip member 73 facilitates the mounting of the first locking structure 70 on the pot body 10. At the same time, the first locking structure 70 can move on the first anti-slip member 73 and prevent the first locking structure 70 from falling off the first anti-slip member 73. The first locking structure 70 of this embodiment also includes a first guide cylinder that is guided and matched with the first anti-slip member 73. The first anti-slip member 73 includes a first guide shaft inserted into the first guide cylinder and a first stop protrusion provided at the bottom end of the first guide shaft, and the first stop protrusion is preferably a first screw. The provision of the first stop protrusion can stop the first locking structure 70 and prevent the first locking structure 70 from falling off the first guide shaft.

[0061] When the lid is opened from the pot body, in order to facilitate the first locking structure 70 to move from the first avoidance position to the first locking position, the cooking utensil also includes a first elastic reset member 74 arranged between the first anti-slip member 73 and the first locking structure 70. The first elastic reset member 74 applies a first elastic force to the first locking structure 70 so that the first locking structure 70 is subjected to a force moving from the first avoidance position to the first locking position. Specifically, when the lid is placed on the pot body, the first locking structure 70 compresses the first elastic reset member 74 to facilitate the first locking structure 70 to move from the first locking position to the first avoidance position. When the lid is opened from the pot body, the first locking structure 70 loses the downward pressure of the lid, and the first locking structure 70 automatically moves from the first avoidance position to the first locking position under the action of the first elastic force of the first elastic reset member 74. The first elastic reset member 74 is preferably a first spring.

[0062] like Figure 2 、 Figure 4 、 Figures 6 to 9 As shown, the second drive structure 50 has a third drive position and a fourth drive position when it rotates. When the second drive structure 50 is in the third drive position, the corresponding first locking mechanism 22 is in the first unlocking position. When the second drive structure 50 is in the fourth drive position, the corresponding first locking mechanism 22 is in the first locking position.

[0063] In this application, the inventors found that the cover can be placed on the pot only when the second drive structure 50 is in the third drive position. If the second drive structure 50 is in the fourth drive position or other positions, the second drive structure 50 or the upper transmission member 43 or the plug-in structure 45 will interfere with the pot, resulting in the cover being unable to be placed on the pot. In order to solve this problem, Figure 2 、 Figure 4 、 Figures 6 to 9 、 Figure 15 and Figure 16As shown, the embodiment of the cooking appliance further includes a second locking structure 80 movably disposed on the lid body 21. The second locking structure 80 has a second avoidance position that avoids movement of the second drive structure 50 and a second locking position that locks the second drive structure 50 in the third drive position. When the second locking mechanism 60 is in the second locked position and the pot body 10 pushes the second locking structure 80 to move and is in the second avoidance position, the second drive structure 50 switches between the third drive position and the fourth drive position. When the second locking mechanism 60 is in the second unlocking position and the second drive structure 50 is in the third drive position, the pot body 10 avoids the second locking structure 80, causing the second locking structure 80 to move and be in the second locked position. In this way, since the second locking structure 80 locks the second drive structure 50 in the third drive position, when the cover body is placed on the pot body again, the second drive structure 50 or the upper transmission member 43 or the plug-in structure 45 will not interfere with the pot body, and the plug-in structure 45 between the lower transmission member 41 and the upper transmission member 43 can be smoothly plugged in, so that the lower transmission member 41 and the upper transmission member 43 are combined together. Then, when the second locking mechanism 60 is in the second locking position, when the first drive structure 30 is moved, it can drive the lower transmission member 41 to rotate, so as to achieve the purpose of driving the upper transmission member 43 to rotate through the plug-in structure 45.

[0064] In this embodiment, the second locking structure 80 is movably provided along the up-down direction of the pot body. Of course, in embodiments not shown in the figures, the second locking structure can be movably provided along the left-right direction or the front-back direction of the pot body.

[0065] like Figure 2 、 Figure 4 、 Figures 6 to 9 、 Figure 11 、 Figure 15 and Figure 16 As shown, the second locking structure 80 includes a hook portion 81 and a second protrusion 82 arranged on the hook portion 81. The second driving structure 50 is provided with a lock hole 53 that cooperates with the hook portion 81. When the pot body 10 pushes the second protrusion 82 and pushes the second protrusion 82 to move upward so that the second locking structure 80 is in the second avoidance position, the hook portion 81 disengages from the lock hole 53.

[0066] When the cover is placed on the pot body, since the second protrusion 82 protrudes downward from the bottom of the cover body, the pot body can first directly contact the bottom of the second protrusion 82 and push the second protrusion 82 upward to move the second protrusion 82 upward. When the second locking mechanism 60 is in the second locking position and the second locking structure 80 is in the second avoidance position, the hook portion 81 disengages from the lock hole 53. At this time, the user operates the first driving structure 30 and drives the second driving structure 50 to switch between the third driving position and the fourth driving position through the lower transmission member 41, the plug-in structure 45, and the upper transmission member 43 in sequence.

[0067] like Figure 2 、 Figure 4 、 Figures 6 to 9 、 Figure 15 and Figure 16 As shown, when the pot body 10 moves to avoid the second protrusion 82, the hook portion 81 is hooked in the lock hole 53, and the second locking structure 80 is now in the second locked position. When the second locking mechanism 60 is in the second unlocked position, the lid body can be opened from the pot body, and the pot body no longer pushes against the second protrusion 82. The pot body avoids the second protrusion 82, and the second protrusion 82 can move downward. The second protrusion 82 reaches a position protruding from the bottom of the lid body again, and the hook portion 81 is hooked in the lock hole 53. In the rotation direction of the second driving structure 50, the lock hole 53 is restricted by the hook portion 81, which facilitates the second locking structure 80 to remain in the second locked position, thereby improving the reliability of the locking of the second locking structure 80.

[0068] It should be noted that when the second locking structure 80 is in the second locking position, the second protrusion 82 protrudes from the bottom of the cover body. When the second locking structure 80 is in the second avoidance position, the second protrusion 82 is higher than or flush with the bottom of the cover body. Specifically, the bottom of the cover body is provided with a second avoidance hole 216 for the second protrusion 82 to protrude from the bottom of the cover body.

[0069] like Figure 2 、 Figure 4 、 Figures 6 to 9 、 Figure 15 and Figure 16 As shown, the cooking utensil also includes a second anti-slip member 83 for mounting the second locking structure 80 on the cover body 21. In this way, the provision of the second anti-slip member 83 facilitates mounting the second anti-slip member 83 on the cover body 21, and the second locking structure 80 can move on the second anti-slip member 83 and prevent the second anti-slip member 83 from falling off the second anti-slip member 83. The second locking structure 80 of this embodiment also includes a second guide cylinder that cooperates with the second anti-slip member 83 for guidance. The second anti-slip member 83 includes a second guide shaft that is inserted into the second guide cylinder and a second stop protrusion that is arranged at the bottom end of the second guide shaft, and the second stop protrusion is preferably a second screw. The provision of the second stop protrusion can stop the second locking structure 80 and prevent the second locking structure 80 from falling off the second guide shaft.

[0070] When the lid is opened from the pot body, in order to facilitate the second locking structure 80 to move from the second avoidance position to the second locking position, the cooking utensil also includes a second elastic reset member 84 arranged between the second anti-slip member 83 and the second locking structure 80. The second elastic reset member 84 applies a second elastic force to the second locking structure 80 so that the second locking structure 80 is subjected to a force moving from the second avoidance position to the second locking position. Specifically, when the lid is placed on the pot body, the second locking structure 80 compresses the second elastic reset member 84 to facilitate the second locking structure 80 to move from the second locking position to the second avoidance position. When the lid is opened from the pot body, the second locking structure 80 loses the upward force of the pot body, and the second locking structure 80 automatically moves from the second avoidance position to the second locking position under the action of the second elastic force of the second elastic reset member 84. The second elastic reset member 84 is preferably a second spring.

[0071] like Figure 2 、 Figure 4 、 Figures 6 to 9 As shown, the first drive structure 30 includes a lower drive body 31 movably arranged on the pot body 10 and a first tooth portion 32 arranged on the lower drive body 31, and the lower transmission member 41 includes a second tooth portion 42 that is in transmission cooperation with the first tooth portion 32. The transmission cooperation between the first tooth portion 32 and the second tooth portion 42 facilitates the transmission of the movement of the lower drive body 31 to the lower transmission member 41, and facilitates the first drive structure 30 to drive the lower transmission member 41 to rotate. The transmission process is smooth, the structure is stable, simple, low-cost and easy to produce. Specifically, the first tooth portion 32 is a first rack, and the second tooth portion 42 is a first gear. Or in other embodiments, the first tooth portion 32 is a first gear, and the second tooth portion 42 is a first rack.

[0072] In this embodiment, a downward extending guide column 131 is provided below the middle plate, and a guide hole 34 is provided on the lower transmission member 41 to guide and cooperate with the guide column 131. The guide hole 34 extends along the left and right directions of the pot body to facilitate the first driving structure 30 to smoothly switch between the first driving position and the second driving position in the left and right directions of the pot body.

[0073] like Figure 2 、 Figure 4 、 Figures 6 to 9As shown, the second drive structure 50 includes an upper drive body 51 rotatably disposed on the cover body 20 and a third tooth portion 52 disposed on the upper drive body 51, and the upper transmission member 43 includes a fourth tooth portion 44 that cooperates with the third tooth portion 52. The transmission cooperation between the third tooth portion 52 and the fourth tooth portion 44 facilitates the transmission of the rotation of the upper transmission member 43 to the upper drive body 51, so that the upper transmission member 43 drives the second drive structure 50 to rotate, and the transmission process is smooth, the structure is stable, simple, low-cost and easy to produce. Specifically, the third tooth portion 52 is a second rack, and the fourth tooth portion 44 is a second gear. Alternatively, in other embodiments, the third tooth portion 52 is a second gear, and the fourth tooth portion 44 is a second rack.

[0074] like Figures 7 to 9 As shown, the cover is placed on the pot body. In order to facilitate the connection or disconnection of the upper transmission member 43 and the lower transmission member 41, the plug-in structure 45 includes a socket 452 and an insert block 451 that can be inserted into the socket 452. The socket 452 is set on the lower transmission member 41, and the insert block 451 is set on the upper transmission member 43. When the insert block 451 is inserted into the socket 452, the cover can be placed on the pot body, and the upper transmission member 43 and the lower transmission member 41 are combined together, facilitating the synchronous rotation of the upper transmission member 43 and the lower transmission member 41. The plug-in cooperation of the above-mentioned socket 452 and the insert block 451 is simple, low-cost and easy to produce.

[0075] In other embodiments, the insert block 451 is provided on the lower transmission member 41 , and the insertion hole 452 is provided on the upper transmission member 43 .

[0076] like Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 12 As shown, to facilitate user actuation of the first drive mechanism 30, the cooking appliance further includes an operating member 91 movably disposed on the pot body 10. Movement of the operating member 91 drives the first drive mechanism 30. The unlocking member 63 is disposed within the operating member 91. Because the unlocking member 63 is movably disposed within the operating member 91 and the unlocking member 63 and operating member 91 are co-located, the user can operate the unlocking member 63 to open the lid after actuating the first drive mechanism 30 via the operating member 91 without having to relocate. This improves user convenience and provides a better product experience.

[0077] In this embodiment, the first locking mechanism 22 includes a locking ring 221 and a cover tooth 222 disposed at the bottom of the locking ring 221. The cover body 21 includes an inner lining 211 disposed outside the locking ring 221 and a surface cover 212 disposed outside the inner lining 211. The second driving structure 50 and the upper transmission member 43 are both disposed on the inner lining 211.

[0078] In this embodiment, the pot body comprises an outer pot 11 and an inner pot 14 disposed within the outer pot 11, with pot teeth 141 disposed on the inner pot 14. The outer pot 11 comprises an outer shell 12 and a center plate 13 disposed on top of the outer shell 12. The outer shell is provided with a second mounting hole 121 and a mounting base 16 disposed therein. The unlocking member 63 and the operating member 91 are both disposed on the mounting base 16. This centralized arrangement of the unlocking member 63 and the operating member 91 further facilitates user operation, enabling both the unhooking and unhooking of the cooking utensil without requiring a change of operating position, significantly improving operational convenience.

[0079] In this embodiment, the inner liner 211 is provided with a first mounting hole 215 for mounting the fourth tooth portion 44. The middle plate 13 is provided with a third mounting hole 133 for mounting the second tooth portion 42. Furthermore, the first mounting hole 215 and the third mounting hole 133 facilitate the insertion and removal of the insert block 451 from the insertion hole 452.

[0080] In this embodiment, the outer pot 11 further comprises a base 15 disposed at the bottom of the outer shell 12. The cooking appliance further comprises a heating device 92 disposed within the pot body 10. The heating device 92 is used to heat the inner pot 14 so as to heat the food within the inner pot.

[0081] Specifically, the unlocking member 63 includes a button 631 and a push rod 632 disposed behind the button 631. The operating member 91 includes a knob 911 and a drive rod 912 disposed behind the knob 911. The knob 911 is provided with a third avoidance hole 913 for avoiding the push rod 632. In this way, when the knob 911 drives the drive rod 912 to rotate, the third avoidance hole 913 provides a avoidance for the push rod 632. The first driving structure 30 is provided with a matching long hole 35 that cooperates with the drive rod 912. The mounting seat 16 is provided with a fourth avoidance hole 161 for avoiding the drive rod 912. A third elastic return member 64 is provided between the mounting seat 16 and the button 631. The third elastic return member 64 applies an elastic return force to the button 631 in a direction away from the mounting seat 16.

[0082] In this embodiment, when the knob 911 drives the driving rod 912 to rotate, the driving rod 912 moves relative to the matching long hole 35 in the matching long hole 35 and pushes the matching long hole 35, so that the first driving structure 30 moves in the left and right directions of the pot body.

[0083] In this embodiment, the bottom of the cover body 21 is provided with a barb 213. The second locking mechanism 60 includes a plate hook 61 swingably provided below the middle plate. The plate hook 61 engages or disengages with the barb 213. When the plate hook 61 engages with the barb 213, the second locking mechanism 60 is in a second locked position. When the plate hook 61 disengages from the barb 213, the second locking mechanism 60 is in a second unlocked position.

[0084] The lower end of the plate hook 61 is a pressure-bearing portion 62 corresponding to the push rod 632. When a user applies pressure to the button 631, the push rod 632 on the button 631 moves backward, causing the plate hook 61 to swing forward. At this time, the plate hook 61 separates from the barb 213. When the user's pressure on the button 631 is removed, the button 631 moves backward and resets under the action of the elastic reset force applied to the button 631 by the third elastic reset member 64. In this embodiment, a reset spring is provided between the plate hook 61 and the middle plate. The reset spring applies a reset force to the plate hook 61. Under the action of the reset force of the reset spring, the plate hook 61 can move from a position separated from the barb 213 to a position engaged with the barb 213.

[0085] like Figure 2 、 Figure 4 、 Figure 9 and Figure 11 As shown, in order to facilitate the rotation of the upper transmission member 43 to drive the second drive structure 50 to swing and drive the first locking mechanism 22 to switch between the first unlocked position and the first locked position. An arc-shaped hole 214 is provided on the cover body 21, and a drive slot 54 is provided at a position corresponding to the arc-shaped hole 214 on the second drive structure 50. A drive post 223 is provided above the first locking mechanism 22 and is inserted through the arc-shaped hole 214 and the drive slot 54. When the upper transmission member 43 rotates, the second drive structure 50 is driven to swing, and the second drive structure 50 drives the first locking mechanism 22 to switch between the first unlocked position and the first locked position through the drive slot 223. The provision of the arc-shaped hole 214 can guide the movement of the drive slot 223, facilitating the smooth switching of the first locking mechanism 22 between the first unlocked position and the first locked position. The provision of the drive slot 54 facilitates the second drive structure 50 to directly drive the drive slot 223.

[0086] The long holes in the aforementioned matching long hole 35 and the driving long hole 54 both include a long side and a short side, and the length of the long side is greater than the length of the short side.

[0087] Specifically, in this embodiment, when the cover teeth of the first locking mechanism 22 of the cooking appliance are separated from the pot teeth 141 to be in the first unlocked position, the tooth removal operation of the cooking appliance is as follows:

[0088] When the user rotates the operating member 91 to the left, the driving rod 912 of the operating member 91 drives the first driving structure 30, which is provided with the matching elongated hole 35, to move leftward. When the first driving structure 30 moves, the first tooth portion 32 cooperates with the second tooth portion 42 to drive the lower transmission member 41 to rotate. When the lower transmission member 41 rotates, the plug block 451 engages with the plug hole 452, and the lower transmission member 41 and the upper transmission member 43 are combined to rotate synchronously with each other. When the upper transmission member 43 rotates, the fourth tooth portion 44 cooperates with the third tooth portion 52 to drive the second driving structure 50 to rotate. The second driving structure 50 drives the first locking mechanism 22 to rotate from the first locked position to the first unlocked position via the driving column 223, at which time the teeth are removed.

[0089] On the contrary, if the user rotates the operating member 91 to the right, the first locking mechanism 22 can be swung from the first unlocking position to the first locking position, and the locking mechanism is realized.

[0090] When the hook 61 of the second locking mechanism 60 of the cooking appliance is separated from the barb 213 to be in the second unlocked position, the cooking appliance is unhooked as follows:

[0091] The user pushes the unlocking member 63 backward, and the push rod 632 of the unlocking member 63 can push the pressure portion 62 of the second locking mechanism 60. The second locking mechanism 60 swings forward in the front-to-back direction, and the plate hook 61 of the second locking mechanism 60 is separated from the barb 213. At this time, the second locking mechanism 60 swings from the second locking position to the second unlocking position. Since the first locking mechanism 22 is in the first unlocking position, the cover body can be directly opened from the pot body 10, and unhooking is achieved at this time.

[0092] On the contrary, when the user puts the cover 20 back on the pot body 10, the barb 213 pushes the plate hook 61 to swing backward. After the barb 213 passes over the plate hook 61, the plate hook 61 is engaged with the barb 213 under the action of the reset spring. At this time, the second locking mechanism 60 swings from the second unlocking position to the second locking position.

[0093] The cooking appliance in this embodiment is an electric pressure cooker. Of course, in embodiments not shown in the figures, the pot body can also be a cup body or an inner pot. The cooking appliance can also be an electric rice cooker, a low-pressure rice cooker, a soybean milk maker, a food processor, a cooking machine, an electric stew pot, a multi-function pot, etc.
