[0037] There are many types of pressure cooker lid opening and closing mechanisms, mainly divided into drop-type, screw-on type, and clamp type. Screw-on pressure cookers are the most widely used and popular due to their simple structure, ease of manufacture, and low cost. Currently, most ordinary round pressure cookers use a twist-on screw-on method, which makes it inconvenient for users to operate due to the angle of their wrist and arm, resulting in an ergonomic problem.

[0038] To address the aforementioned problems, the present invention provides a pot lid assembly and a cooking appliance having the pot lid assembly. Figures 1 to 4 An embodiment of the cooking utensil provided by this utility model.

[0039] Please see Figures 1 to 4The cooking appliance 100 can be a cooking machine, rice cooker, induction cooker, etc. Specifically, in the embodiment of the present invention, the cooking appliance 100 is a pressure cooking appliance 100, specifically a pressure cooker. The cooking appliance 100 includes a pot body 101 and a lid assembly 102 that covers the open end of the pot body 101. Generally speaking, an inner pot is also provided inside the pot body 101. The lid assembly 102 and the inner pot together form a cooking cavity.

[0040] The pot lid assembly 102 includes a lid body 1, an opening / closing member 2, and a driving assembly 3. The opening / closing member 2 is movably disposed inside the lid body 1 so that it has a locking position for locking with the pot body 101 and an unlocking position for unlocking from the pot body 101 during its active stroke. The driving assembly 3 includes an operating part 31 movably disposed on the lid body 1 in the thickness direction, and a transmission mechanism 32 that drives the operating part 31 and the opening / closing member 2. The transmission mechanism 32 converts the movement of the operating part 31 into the movement of the opening / closing member 2.

[0041] In the technical solution provided by the present invention, the pot lid assembly 102 includes a lid body 1, an opening / closing component 2, and a driving assembly 3. The opening / closing component 2 is movably disposed on the inner side of the lid body 1 so as to have a locking position for locking with the pot body 101 and an unlocking position for unlocking from the pot body 101 during its active stroke. The driving assembly 3 includes an operating part 31 movably disposed on the lid body 1 in the thickness direction of the lid body 1, and a transmission mechanism 32 that drives the operating part 31 and the opening / closing component 2. The transmission mechanism 32 converts the activity of the operating part 31 into the activity of the opening / closing component 2. Therefore, the opening / closing component 2 can be unlocked directly by the activity of the operating part 31 in the thickness direction of the lid body 1. Compared with the traditional twisting screw-on method, the technical solution of the present invention only requires the user to apply force in the thickness direction of the lid body 1 when driving the opening / closing component 2 to unlock, making the operation more convenient for the user and conforming to ergonomics.

[0042] As mentioned above, the lid 1 cannot rotate relative to the pot 101. Therefore, a limiting structure needs to be provided between the lid 1 and the pot 101. The specific limiting structure is not limited. In the embodiment of the present invention, a limiting protrusion 11 extends laterally from the periphery of the lid 1. The limiting protrusion 11 cooperates with the recess 101a on the side of the opening end of the pot 101 to limit the lid 1 and restrict its rotation. Furthermore, multiple limiting protrusions 11 and recesses 101a can be provided to obtain a more stable limiting effect. Specifically, in the embodiment of the present invention, two limiting protrusions 11 are provided and are provided on opposite sides of the lid 1. Correspondingly, two recesses 101a are also provided.

[0043] Furthermore, in an embodiment of the present invention, a handle 101b is provided on the outer side of the opening end of the pot body 101, and the recess 101a is provided on the handle 101b, so that no additional components are needed to provide the recess 101a.

[0044] The opening and closing component 2 is movably disposed inside the lid 1. The specific movement is not limited. The opening and closing component 2 can move radially along the lid 1. In this case, the opening and closing component 2 and the pot body 101 can be locked together by a clamp. Of course, the opening and closing component 2 can also be rotatably installed on the lid 1. In this case, the opening and closing component 2 and the pot body 101 can be locked together by a snap fastener and a pot fastener. Therefore, the present invention does not limit the specific movement form of the opening and closing component 2. The key point of this invention is that the movement of the operating part 31 in the thickness direction of the cover 1 drives the movement of the opening / closing member 2. Because the movement form of the opening / closing member 2 is not limited, the driving mechanism is also not limited. For example, when the opening / closing member 2 moves radially along the cover 1, and the driving mechanism converts linear motion into linear motion in another direction, with these two linear motion directions forming a three-dimensional angle, then the driving mechanism can be a driving protrusion and a driving rod, with the driving protrusion abutting against the driving rod for extension and retraction. When the opening / closing member 2 can also be rotatably mounted on the cover 1, the driving mechanism converts linear motion into rotation, and the driving mechanism can be a driving inclined surface 321 and an abutment part 322, with the driving inclined surface 321 driving the abutment part 322. The specific structure of the driving mechanism will be described later.

[0045] In an embodiment of the present invention, the opening and closing member 2 is rotatably mounted on the inner side of the cover 1, and its axis of rotation extends along the thickness direction of the cover 1. The transmission mechanism 32 includes a driving inclined surface 321 and an abutting part 322 that are arranged opposite to each other in the circumferential direction of the opening and closing member 2. The driving inclined surface 321 is inclined in the thickness direction of the cover 1. One of the driving inclined surface 321 and the abutting part 322 is provided on the operating part 31, and the other is provided at a position on the opening and closing member 2 that is offset from its axis of rotation. That is, the driving inclined surface 321 can be disposed on the operating part 31, and the abutting part 322 can be disposed on the opening and closing member 2. Alternatively, the driving inclined surface 321 can be disposed on the opening and closing member 2, and the abutting part 322 can be disposed on the operating part 31. Specifically, in the embodiment of the present invention, the driving inclined surface 321 is disposed on the operating part 31, and the abutting part 322 is disposed on the opening and closing member 2. In this way, the driving inclined surface 321 and the abutting part 322 interact to drive the opening and closing member 2 to rotate, so that the transmission mechanism 32 has a simple structure. Furthermore, by setting the driving inclined surface 321 and the abutting part 322 at a position that is far enough away from the axis of rotation of the opening and closing member 2, a large torque can be obtained under a small force, so that the user can operate the operating part 31 with less effort.

[0046] As described above, the opening and closing component 2 can be locked to the pot body 101 using a clamp structure, or it can be locked to each other by fasteners and pot teeth. In the embodiment of the present invention, the latter is adopted. Specifically, the opening and closing component 2 includes an inner cover 2a rotatably installed on the inner side of the cover body 1. The periphery of the inner cover 2a is provided with fasteners for engaging with the pot body 101. That is, the periphery of the inner cover 2a is provided with fasteners, and the opening end of the pot body 101 is provided with pot teeth. Such structures are relatively common structures, so they will not be described in detail here.

[0047] To facilitate user gripping of the pot lid assembly 102, in an embodiment of the present invention, a handle 4 is provided on the outer side of the lid body 1. The user can lift the pot lid assembly 102 by gripping the handle 4. Specifically, in an embodiment of the present invention, the handle 4 includes a connecting end 41 connected to the outer side of the lid body 1 and a gripping section 42 connected to the connecting end 41 and spaced apart from the lid body 1. The gripping section 42 is for the user to grip. It should be noted that the handle 4 may be connected to the lid body 1 at only one end, i.e., through the connecting end 41, i.e., the handle 4 is cantilevered, or both ends of the handle 4 may be connected to the lid body 1, i.e., in addition to being connected to the lid body 1 through the connecting end 41, it is also connected to the lid body 1 through the other end opposite to the connecting end 41. In an embodiment of the present invention, the operating part 31 is disposed on the grip section 42 and is movably mounted on the cover 1 via the handle 4. Since the grip section 42 has a gap with the outer side of the cover 1, that is, as a protruding part on the cover 1, the operation part 31 is disposed on the grip section 42, making it more convenient for the user to operate.

[0048] Furthermore, in an embodiment of the present invention, the grip section 42 has an inner side facing the cover 1, and the operating part 31 is movably disposed on the inner side of the grip section 42. When the user grips the grip section 42, in a normal gripping manner, the user's hand grips the grip section 42 from the inside, and thus can directly press the operating part 31 while gripping, which conforms to the user's operating habits. Moreover, placing the operating part 31 on the inside of the grip section 42 can hide the operating part 31. In addition, the operating part 31 can also be disposed in other parts of the grip, for example, on the outer side of the grip section 42 opposite to its inner side.

[0049] Furthermore, in an embodiment of the present invention, a first elastic reset member 5 is provided between the operating part 31 and the grip section 42. The first elastic reset member 5 is used to reset the operating part 31 in a direction away from the grip section 42. Specifically, the first elastic reset member 5 is a spring. Thus, the operating part 31 is elastically mounted by the first elastic reset member 5, so that the user has a damping feeling when operating the operating part 31, and the spring provides a reset force after being pressed and deformed, so that the operating part 31 can be reset in a direction away from the grip section 42.

[0050] In an embodiment of the present invention, the opening / closing member 2 is provided with a driving member 21. The driving member 21 includes a connecting section 211 connected to the opening / closing member 2 and extending along the thickness direction of the cover 1, and a mating section 212 extending laterally from the connecting section 211 and laterally opposite to the operating part 31. Specifically, in an embodiment of the present invention, the connecting section 211 is located at the connecting end 41 of the handle 4, and the mating section 212 extends along the length direction of the gripping section 42 of the handle 4, and the mating section 212 is located in the gripping section 42. Thus, the handle 4 hides the mating section 212 of the driving member 21 within it. The abutting portion 322 and the driving inclined surface 321 are respectively disposed on the side opposite to the mating section 212 and the operating portion 31. Alternatively, the driving inclined surface 321 can be disposed on the side of the operating portion 31 facing the mating section 212, and the abutting portion 322 can be formed on the side of the mating section 212 facing the operating portion 31. Or, the abutting portion 322 can be disposed on the side of the operating portion 31 facing the mating section 212, and the driving inclined surface 321 can be formed on the side of the mating section 212 facing the operating portion 31. Specifically, in an embodiment of the present invention, the driving inclined surface 321 is disposed on the side of the operating portion 31 facing the mating section 212, and the abutting portion 322 is formed on the side of the mating section 212 facing the operating portion 31. Specifically, the abutting portion 322 is integrally formed on the mating section 212. Therefore, since the mating section 212 extends laterally along the connecting section 211, it can be arranged more flexibly and can extend in a direction away from the axis of rotation of the opening and closing member 2, so that the driving inclined surface 321 and the abutment portion 322 are far enough away from the axis of rotation.

[0051] In an embodiment of the present invention, a second elastic reset member 6 is provided between the inner cover 2a and the cover body 1. The second elastic reset member 6 is used to reset the inner cover 2a to the latch position. Specifically, the second elastic reset member 6 is a spring extending circumferentially along the inner cover 2a, and one end of the spring is connected to a protrusion on the inner cover 2a, and the other end is connected to the cover body 1.

[0052] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
