Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and in particular to lids and cooking utensils. Background Technology

[0002] Cooking appliances are used to process food and include types such as rice cookers and pressure cookers. Generally, cooking appliances consist of a pot body and a lid, with the lid being openable and closable relative to the pot body. When the lid is on the pot body, a cooking space is formed between the lid and the pot body. When the cooking appliance is working, the pressure in the cooking space increases, which may cause the lid to open abnormally. The high-temperature, high-pressure steam from inside the pot may escape and burn the user, indicating that the safety performance of cooking appliances is relatively low. Summary of the Invention

[0003] Therefore, it is necessary to provide a lid and cooking utensil to improve the safety performance of cooking utensil.

[0004] A lid, provided on a cooking utensil, comprising:

[0005] Top cover;

[0006] A lid assembly is provided on the upper lid, having a clamping state for clamping the upper lid and the inner pot and an unlocking state for releasing the upper lid and the inner pot;

[0007] A pressure valve is provided at the exhaust port of the upper cover, and has a pressure-accumulating state that seals the exhaust port and a pressure-relieving state that opens the exhaust port;

[0008] A control component is located between the lid closing assembly and the pressure valve, and has a limit state that locks the lid closing assembly in the clamping state and a release state that allows the lid closing assembly to move.

[0009] When the control component is in the limit state, it drives the pressure valve to switch to the pressure storage state; when the control component is in the release state, it drives the pressure valve to switch to the pressure relief state.

[0010] In the aforementioned lid design, the pressure valve is only activated to store pressure when the lid assembly is locked in a clamped state via a mechanical linkage of the control components. If the lid assembly is not locked, the pressure valve will not pressurize, preventing the formation of a high-temperature, high-pressure airflow within the pot. This also eliminates the danger of the lid opening unexpectedly during cooking. Furthermore, after cooking, the actuation control component switches to a release state, allowing the lid assembly to open and simultaneously activating the pressure valve to release pressure, ensuring that the pressure inside the pot is balanced with atmospheric pressure and preventing the danger of the lid opening. This design effectively avoids the danger of the lid opening during and after cooking, improving the safety performance of the cooking appliance.

[0011] In one embodiment, the control component includes a limiting member that reciprocates between a limiting position where the lid assembly is locked in the clamped state and a releasing position where the lid assembly is allowed to move.

[0012] In one embodiment, the lid assembly includes a locking ring and a claw, the locking ring being rotatably disposed on the upper lid, the claw being kinetically connected to the locking ring and moving radially along the locking ring as the locking ring rotates to clamp or release the upper lid from the inner pot;

[0013] The locking ring has a slot; when the cover assembly is switched to the clamping state, the opening of the slot faces the limiting member, and the limiting member can extend into the slot and abut against the inner wall of the slot along the circumferential direction of the locking ring.

[0014] In one embodiment, the control component further includes a pressure regulating component disposed between the limiting member and the pressure valve;

[0015] When the limiting member is in the limiting position, the pressure regulating member drives the pressure valve to the pressure storage state under the drive of the limiting member; when the limiting member is in the releasing position, the pressure regulating member drives the pressure valve to the pressure release state under the drive of the limiting member.

[0016] In one embodiment, the limiting member reciprocates between the limiting position and the releasing position along a first direction, and the pressure regulating member moves up and down relative to the upper cover along a second direction intersecting the first direction under the drive of the limiting member, thereby driving the pressure valve to switch between the pressure storage state and the pressure release state.

[0017] In one embodiment, the pressure valve includes an exhaust pipe and a valve body, one end of the exhaust pipe being connected to the exhaust port, and the other end of the exhaust pipe protruding from the upper cover and fitted with the movable valve body;

[0018] When the pressure regulating component rises relative to the upper cover, it pushes the valve body to open the exhaust pipe; when the pressure regulating component falls relative to the upper cover, it allows the valve body to close the exhaust pipe under its own gravity.

[0019] In one embodiment, the valve body includes a main body and a seal. The main body has a mounting groove. One end of the exhaust pipe away from the exhaust port extends into the mounting groove and has a gap with the inner wall of the mounting groove. The seal is fixed to the inner wall of the mounting groove relative to the exhaust pipe.

[0020] In one embodiment, the limiting member includes a mating portion that supports the pressure regulating member, and the pressure regulating member abuts between the mating portion and the valve body;

[0021] Furthermore, the mating part has an inclined surface, which is inclined away from the valve body in the direction from the limiting position to the release position.

[0022] In one embodiment, the limiting member further includes a handle, which is intersected and connected to the mating portion.

[0023] In one embodiment, the elastic element is sleeved outside the pressure regulating element and abuts against the convex ring on the outer periphery of the upper cover and the pressure regulating element, for storing the elastic potential energy that drives the pressure regulating element to descend relative to the upper cover.

[0030] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0031] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] like Figure 1 As shown, in one embodiment of the present invention, a cooking utensil 200 is provided, including a pot body 210, an inner pot 230, and a lid 100. The inner pot 230 is detachably fitted inside the pot body 210, and the lid 100 is openable and closable relative to the pot body 210 to close or open the pot body 210. Specifically, the lid 100 includes an upper cover 10. When the lid 100 is placed on the pot body 210, a cooking space 220 is formed between the upper cover 10 and the inner pot 230, so as to utilize the cooking space 220 for food processing.

[0034] like Figure 2-5 As shown, the lid 100 includes a lid-closing assembly 30, a pressure valve 50, and a control assembly 70, all disposed on the upper lid 10. The lid-closing assembly 30 has a clamping state that clamps the upper lid 10 and the inner pot 230, and an unlocking state that releases the upper lid 10 and the inner pot 230. The pressure valve 50 is disposed at the vent 11 of the upper lid 10, and has a pressure-accumulating state that seals the vent 11, and a pressure-releasing state that opens the vent 11. The control assembly 70 has a limiting state that locks the lid-closing assembly 30 in the clamping state, and a releasing state that allows the lid-closing assembly 30 to move. When the control assembly 70 is in the limiting state, it drives the pressure valve 50 to switch to the pressure-accumulating state; when the control assembly 70 is in the releasing state, it drives the pressure valve 50 to switch to the pressure-releasing state.

[0035] When high-pressure cooking is carried out in the cooking space 220, the pressure valve 50 can close the exhaust port 11 to accumulate pressure. At the same time, the lid assembly 30 clamps the upper lid 10 and the inner pot 230 to prevent the lid 100 from opening abnormally and to protect the operator. When cooking is complete and the lid needs to be opened, the pressure valve 50 opens the exhaust port 11 to release the pressure in the cooking space 220, preventing high-pressure airflow from scalding the operator when the lid is opened.

[0036] Furthermore, a control component 70 is provided in the cooking appliance 200, which can be manually switched between a limit state and a release state. Before cooking, the lid assembly 30 is switched to the clamping state, locking the upper lid 10 and the inner pot 230. Simultaneously, to prevent the lid assembly 30 from loosening during cooking, the control component 70 needs to be switched to the limit state, locking the clamped lid assembly 30 and restricting its movement to prevent accidental opening during cooking. Moreover, only when the limit component is switched to the limit state will the pressure valve 50 switch to the pressure-accumulating state, closing the exhaust port 11 and pressurizing the cooking space 220. If the user forgets to switch the control component 70 to the limit state and fails to lock the clamped lid assembly 30, the pressure valve 50 cannot switch to the pressure-accumulating state, preventing excessive steam pressure and temperature inside the pot. Therefore, when the unlocked lid assembly 30 fails and the lid 100 opens abnormally, no high-temperature, high-pressure steam will escape, avoiding the danger of opening the lid. After cooking is completed, the motion control component 70 switches to the release state, allowing the lid closing component 30 to move, and at the same time, it drives the pressure valve 50 to switch to the pressure relief state, ensuring that the gas pressure inside the pot is balanced with the atmospheric pressure and avoiding the danger of opening the lid.

[0037] In other words, the pressure valve 50 is only activated to store pressure when the lid-closing component 30 is locked in a clamped state via the mechanical linkage of the control component 70. If the lid-closing component 30 is not locked, the pressure valve 50 will not pressurize, preventing the formation of a high-temperature, high-pressure airflow within the pot body 210. Therefore, there is no danger of the lid opening abnormally during cooking. Furthermore, after cooking, the action control component 70 switches to a release state, allowing the lid-closing component 30 to open, while simultaneously switching the pressure valve 50 to a depressurization state. This ensures that the gas pressure inside the pot is balanced with atmospheric pressure, preventing the danger of the lid opening. Thus, the danger of the lid opening during and after cooking is avoided, improving the safety performance of the cooking appliance 200.

[0038] like Figure 1 and Figure 3 As shown, the lid assembly 30 includes a locking ring 32 and a claw 34. The locking ring 32 is rotatably mounted on the upper lid 10. The claw 34 is kinetically connected to the locking ring 32 and moves radially along the locking ring 32 when the locking ring 32 rotates to clamp or release the upper lid 10 and the inner pot 230. When the locking ring 32 rotates around its own center, it drives the claw 34 to reciprocate radially along the locking ring 32 to clamp the edge of the inner pot 230 and the upper lid 10, or to move away from the edge of the inner pot 230 and the upper lid 10, thereby achieving the function of locking the upper lid 10 and the pot body 210.

[0039] Furthermore, a pin is provided on one of the locking ring 32 and the pawl 34, and a groove is provided on the other of the locking ring 32 and the pawl 34 that is circumferentially inclined relative to the locking ring 32. The pin is slidably inserted into the groove. When the pin slides relative to the inner wall of the groove, the circumferential rotation of the locking ring 32 is converted into driving the pawl 34 to move radially along the locking ring 32, thereby realizing the locking and releasing of the pawl 34.

[0040] like Figure 2-4 As shown, the control component 70 includes a limiting member 72, which reciprocates between a locked position where the lid-closing component 30 is in a clamped state and a release position where the lid-closing component 30 is allowed to move. The reciprocating movement of the limiting member 72 restricts or allows the movement of the lid-closing component 30 in the clamped state. Optionally, the limiting member 72 includes a handle 721, which a user can grasp to push the limiting member 72 reciprocating between the locked position and the release position.

[0041] In some embodiments, the locking ring 32 has a slot 31; when the closing assembly 30 is switched to the clamping state, the opening of the slot 31 faces the limiting member 72, and the limiting member 72 can extend into the slot 31 and abut against the inner wall of the slot 31 along the circumferential direction of the locking ring 32 to prevent the locking ring 32 in the clamping state from rotating, thereby locking the closing assembly 30 in the clamping state and preventing the closing assembly 30 from moving.

[0042] The control assembly 70 also includes a pressure regulating component 74 disposed between the limiting member 72 and the pressure valve 50. When the limiting member 72 is in the limiting position, the pressure regulating component 74, driven by the limiting member 72, causes the pressure valve 50 to enter a pressure storage state (e.g., Figure 3 (As shown); When the limiting member 72 is in the released state, the pressure regulating member 74, driven by the limiting member 72, causes the pressure valve 50 to be in the depressurization state (as shown). Figure 4 (As shown). Thus, when the limiting member 72 switches between the limiting position and the release position, it can be linked to the pressure regulating member 74, causing the pressure regulating member 74 to switch the pressure valve 50 between the pressure accumulating state and the pressure releasing state. When the limiting member 72 locks the lid assembly 30, the pressure valve 50 will be driven to the pressure accumulating state to prevent high-temperature steam leakage when the lid assembly 30 is not locked, thus avoiding danger during cooking; when the limiting member 72 releases the lock on the lid assembly 30, the pressure valve 50 will be driven to the pressure accumulating state to balance the pressure inside the pot with the external atmospheric pressure, so that the lid can be opened after pressure release, protecting the user.

[0043] In some embodiments, the limiting member 72 reciprocates between a limiting position and a releasing position along a first direction, and the pressure regulating member 74 moves up and down relative to the upper cover 10 along a second direction intersecting the first direction under the drive of the limiting member 72, thereby causing the pressure valve 50 to switch between a pressure accumulating state and a pressure releasing state. That is, when the limiting member 72 moves along the first direction to block the cover closing assembly 30, the pressure regulating member 74 moves along a second direction different from the first direction, which can change the state of the pressure valve 50.

[0044] like Figure 2 and Figure 5 As shown, the pressure valve 50 includes an exhaust pipe 52 and a valve body 54. One end of the exhaust pipe 52 is connected to the exhaust port 11, and the other end of the exhaust pipe 52 protrudes from the upper cover 10 and is fitted with a movable valve body 54. When the pressure regulating member 74 rises relative to the upper cover 10, it pushes the valve body 54 to open the exhaust pipe 52. When the pressure regulating member 74 falls relative to the upper cover 10, it allows the valve body 54 to close the exhaust pipe 52 under its own weight. A movable valve body 54 is fitted at the end of the exhaust pipe 52. In its natural state, the valve body 54 closes the exhaust pipe 52, but when the valve body 54 is pushed by the pressure regulating member 74, it can move relative to the exhaust pipe 52, opening the movable pipe to connect the exhaust port 11 to the outside.

[0045] Specifically, the valve body 54 includes a main body 541 and a sealing element 543. The main body 541 has a mounting groove 542. The end of the exhaust pipe 52 furthest from the exhaust port 11 extends into the mounting groove 542 and has a gap with the inner wall of the mounting groove 542, allowing the valve body 54 to move around the exhaust pipe 52. Furthermore, the sealing element 543 is fixed to the inner wall of the mounting groove 542 relative to the exhaust pipe 52. When the main body 541 is fitted onto the exhaust pipe 52, the sealing element 543 relative to the exhaust pipe 52 can cover the exhaust pipe 52 to seal it. When the main body 541 is pushed by the pressure regulating element 74, the sealing element 543 moves synchronously with the main body 541 to open the exhaust pipe 52. Optionally, the sealing element 543 is conical and fitted inside the exhaust pipe 52.

[0046] Furthermore, the limiting member 72 includes a mating portion 723 supporting the pressure regulating member 74, with the pressure regulating member 74 abutting between the mating portion 723 and the valve body 54; and the mating portion 723 has an inclined surface 722, which is inclined away from the valve body 54 in the direction from the limiting position to the release position. When the limiting member 72 moves between the limiting position and the release position along the first direction, the movement of the limiting member 72 along the first direction is converted into the lifting and lowering of the pressure regulating member 74 in the second direction by the inclined surface 722. Furthermore, the side of the inclined surface 722 closer to the release position is lower than the side of the inclined surface 722 closer to the limit position. Thus, when the limit member 72 moves to the limit position, the lower part of the inclined surface 722 corresponds to the pressure regulating member 74, allowing the pressure regulating member 74 to descend relative to the upper cover 10, and allowing the valve body 54 to reset and close the exhaust pipe 52 under its own gravity. When the limit member 72 moves to the release position, the higher part of the inclined surface 722 corresponds to the pressure regulating member 74, pushing the pressure regulating member 74 to float upward, and then pushing the valve body 54 to tilt with the exhaust pipe 52 as the fulcrum through the pressure regulating member 74, opening the exhaust pipe 52 to release pressure.

[0047] Optionally, the handle 721 of the limiting member 72 is intersected and connected to the mating part 723, so that the user can push the mating part 723 to move after holding the handle 721.

[0048] Furthermore, the control assembly 70 also includes an elastic element 76, which is sleeved around the pressure regulating member 74 and abuts against the convex ring 741 on the outer periphery of the upper cover 10 and the pressure regulating member 74. The elastic element 76 stores the elastic potential energy that drives the pressure regulating member 74 to descend relative to the upper cover 10. When the pressure regulating member 74 floats relative to the upper cover 10 under the action of the inclined surface 722, it presses against the elastic element 76 abutting between the convex ring 741 on the outer periphery of the pressure regulating member 74 and the upper cover 10. When the pressure regulating member 74 descends relative to the upper cover 10 under the action of the inclined surface 722, the elastic element 76 pushes the pressure regulating member 74 downward and abuts against the mating part 723, ensuring that the pressure regulating member 74 and the mating part are always in contact and that they can reliably transmit power.

[0049] The upper cover 10 includes a bottom plate 12 and a housing 14 that are connected to each other. The housing 14 is fastened to the bottom plate 12, and an assembly space 13 is formed between the housing 14 and the upper cover 10. The mating part 723 of the limiting member 72 extends into the assembly space 13 and is movably disposed on the bottom plate 12. The handle 721 of the limiting member 72 extends out of the assembly space 13 for easy gripping by the user. The exhaust pipe 52 in the pressure valve 50 is connected to the exhaust port 11 on the bottom plate 12 and extends out of the housing 14 through the assembly space 13. The valve body 54 is located outside the assembly space 13 and is movably fitted onto the end of the exhaust pipe 52. One end of the pressure regulating member 74 is located inside the assembly space 13 and abuts against the mating part 723. The other end of the pressure regulating member 74 can pass through the housing 14 and abut against the valve body 54. Furthermore, the elastic element 76 abuts against the convex ring 741 on the outer periphery of the upper cover 10 and the pressure regulating element 74. When the pressure regulating element 74 floats up, the elastic element 76 is compressed; when the pressure regulating element 74 descends, the elastic element 76 releases the stored elastic potential energy and stretches.

[0050] Based on the same inventive concept, in one embodiment of the present invention, a cover 100 as described above is also provided. The cover 100 includes a closing assembly 30, a pressure valve 50, and a control assembly 70, all disposed on the upper cover 10. The closing assembly 30 has a clamping state that clamps the upper cover 10 and the inner pot 230, and an unlocking state that releases the upper cover 10 and the inner pot 230. The pressure valve 50 is disposed at the vent 11 of the upper cover 10, and has a pressure-accumulating state that seals the vent 11, and a pressure-releasing state that opens the vent 11. The control assembly 70 has a limiting state that locks the closing assembly 30 in the clamping state, and a releasing state that allows the closing assembly 30 to move. When the control assembly 70 is in the limiting state, it drives the pressure valve 50 to switch to the pressure-accumulating state; when the control assembly 70 is in the releasing state, it drives the pressure valve 50 to switch to the pressure-releasing state.

[0051] In other words, the pressure valve 50 is only activated to store pressure when the lid-closing component 30 is locked in a clamped state via the mechanical linkage of the control component 70. If the lid-closing component 30 is not locked, the pressure valve 50 will not pressurize, preventing the formation of a high-temperature, high-pressure airflow within the pot body 210. Therefore, there is no danger of the lid opening abnormally during cooking. Furthermore, after cooking, the action control component 70 switches to a release state, allowing the lid-closing component 30 to open, while simultaneously switching the pressure valve 50 to a depressurization state, balancing the pressure inside the pot with atmospheric pressure and preventing the danger of the lid opening. This avoids the danger of the lid opening during and after cooking, improving the safety performance of the cooking appliance 200.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
