Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a cooking utensil. Background Technology

[0002] To improve cooking efficiency, more and more cooking appliances offer pressure cooking functions. For example, in addition to traditional pressure cookers, some rice cookers can also cook at pressures higher than atmospheric pressure, often referred to as micro-pressure rice cookers.

[0003] In some models of pressure cookers and micro-pressure rice cookers, the lid is rotatably connected to the pot body. The lid has an opening button on the end opposite the connection point, allowing it to rotate up and down around the connection to open and close. During pressure cooking, to ensure proper operation and equipment safety, user opening of the lid needs to be strictly limited. Therefore, a float valve is often installed on the lid. When the pressure inside the pot increases, the float valve is pushed up by the pressure, thus blocking the opening mechanism and preventing the opening button from being pressed, thus preventing the user from opening the lid.

[0004] Under normal circumstances, the pressure cooker can release pressure and allow the user to open the lid after cooking. However, if a sudden power outage occurs during pressure cooking, the cooking process is terminated. In this case, if the user needs to open the lid, they must wait for a considerable amount of time for the pressure to drop to near atmospheric pressure and for the pot to cool completely before the float valve finally drops. This excessively long waiting time for opening the lid affects normal user operation.

[0005] Furthermore, some models that cannot manually release pressure lack a pressure release button or other operating components on the lid, preventing users from releasing pressure as needed. Users can only control automatic pressure release through the cooking appliance's program. Consequently, after a power outage, pressure release relies solely on natural cooling, further prolonging the pressure reduction process and increasing the user's waiting time. Utility Model Content

[0006] This utility model provides a cooking appliance to solve the problem that when the device loses power during cooking, the user cannot manually release the pressure, the pressure inside the pot decreases slowly, and the user has to wait a long time to open the lid.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A cooking appliance includes a pot body and a pot lid. The pot lid has a connecting end and an opening / closing end that are disposed opposite to each other. The connecting end is rotatably connected to the pot body. The opening / closing end is provided with an opening button. The pot lid is also provided with a solenoid valve, a driving component, and a pressure relief valve. The pot lid has a pressure relief port. The pressure relief valve blocks the pressure relief port. The solenoid valve has a push rod. The driving component is disposed between the opening button and the solenoid valve. The driving component has an operating end that protrudes through the opening button for external tool operation. The driving component can push the push rod so that the push rod drives the pressure relief valve to move and open the pressure relief port.

[0009] In this invention, the pot lid is equipped with a solenoid valve, which is electrically connected to the control unit of the cooking appliance. Its push rod is used to move the pressure relief valve to open the pressure relief port, thereby achieving automatic pressure release. Under normal circumstances, after pressure cooking is completed, the push rod of the solenoid valve is controlled by the program to lift the pressure relief valve, opening the pressure relief port for pressure release. Simultaneously, the pot lid also has a partially exposed driving component that can drive the push rod, thus enabling manual pressure release. When the appliance is powered off during cooking, the user can operate the driving component to drive the push rod of the solenoid valve, causing the push rod to lift the pressure relief valve and open the pressure relief port for pressure release. This integrates automatic and manual pressure release functions of the cooking appliance, and both pressure release methods are controlled by the solenoid valve. Therefore, the same component controls the pressure relief valve, eliminating the need for an additional driving mechanism for the pressure relief valve, simplifying the pot lid structure, saving internal space, and reducing costs.

[0010] Furthermore, the operating end of the actuator is located externally, passing through the lid-opening button, thus integrating the actuator and the button. This eliminates the need for a separate location on the lid for the actuator or manual venting mechanism, improving the lid's aesthetics and making operation simpler and more convenient for users. On the other hand, because the operating end of the actuator is in the same position as the lid-opening button, the button cannot be pressed when the pot is pressurized. Users can operate the actuator independently, causing it to push the pressure relief valve to release pressure via a push rod. Moreover, after normal pressure cooking is complete and the automatic pressure release is finished via program control, users can simultaneously press the lid-opening button and the actuator when opening the lid. This causes the pressure relief valve to be pushed up again as the lid opens, facilitating the release of residual gas and ensuring safe opening, preventing the pressure inside the pot from rising again due to residual heat.

[0011] The lid opening button is located on the side of the pot lid, and the driving component is arranged radially along the pot lid. Both the lid opening button and the driving component can move radially along the pot lid.

[0012] In this design, the movement paths of both the lid-opening button and the drive mechanism are radial to the lid. This ensures that their movement paths are identical, further simplifying user operation and enabling simultaneous operation—that is, pressing both the lid-opening button and the drive mechanism at the same time to lift the pressure relief valve during lid opening. Furthermore, it effectively saves space in the height direction of the lid, contributing to a thinner and lighter lid design.

[0013] The pot lid is also equipped with a button base fixed to the pot lid. The button base has a guide channel extending radially along the pot lid, and the lid opening button is located in the guide channel.

[0014] In this design, the lid opening button is located within the guide channel of the button holder and can slide back and forth along the extension direction of the guide channel. The guide channel extends radially along the lid, which can restrict the movement path of the lid opening button to the radial direction of the lid, making the movement of the lid opening button more reliable and smooth, and reducing the probability of the lid opening button getting stuck.

[0015] The driving component also includes a driving part and a linkage part. The driving part is located between the cover opening button and the button base, and the linkage part is located between the button base and the solenoid valve. An elastic reset part is sleeved on the outer periphery of the driving part. The elastic reset part is used to push the cover opening button to move and reset.

[0016] In this design, when the user operates the control terminal, the drive unit and the linkage unit move synchronously, thereby driving the push rod of the solenoid valve through the linkage unit. The drive unit is located between the cover opening button and the button seat, and an elastic element is sleeved on its exterior. The elastic element can reset the drive unit. When the user presses the drive unit, the elastic element is compressed; when the user stops pressing, the elastic element pushes the drive unit back to its original position. At the same time, the drive unit can also limit the elastic element, ensuring that the elastic element can only deform along the axial direction, preventing skewness and ensuring that the direction of the elastic force is stable and reliable.

[0017] The push rod is arranged horizontally and has an actuating end for driving the pressure relief valve. A transmission component is provided between the actuating end and the pressure relief valve. The transmission component includes a driving end, a trigger end, and a connecting part located between the driving end and the trigger end. The connecting part is rotatably connected to the pot lid. The actuating end can horizontally push the driving end to make the transmission component rotate around the connecting part, so that the trigger end lifts the pressure relief valve to open the pressure relief port.

[0018] In this design, the solenoid valve's push rod is horizontally arranged, which not only saves internal space in the pot lid but also facilitates its coordination with the lid-opening button and the drive mechanism. A transmission mechanism is installed between the solenoid valve and the pressure relief valve. The connecting part of the transmission mechanism is rotatably connected to the pot lid, making the transmission mechanism a lever structure. When the actuating end of the push rod pushes against the driving end of the transmission mechanism, the driving end swings downward, causing the entire transmission mechanism to rotate around the connecting part. The trigger end then lifts upward, thus raising the pressure relief valve and opening the pressure relief port. The lever structure allows for adjustment of the lever arm length, making it easier for the push rod to lift the pressure relief valve via the transmission mechanism, thereby reducing the effort required for user operation.

[0019] The drive end is provided with a transmission ramp, and the action end acts on the transmission ramp; the trigger end is provided with a downwardly bent recessed section, which is used to cooperate with the pressure relief valve.

[0020] In this design, the drive end's inclined surface can convert a portion of the horizontal pushing force from the action end into a vertically downward pressing force, allowing it to swing downwards when pushed by the action end, causing the trigger end to swing upwards. The downward-bent recessed section of the trigger end, in conjunction with the pressure relief valve, reduces the space occupied in the height direction by the transmission components and helps to reduce the height of the pressure relief valve, thereby saving space in the height direction of the pot lid.

[0021] The push rod is arranged horizontally and has an actuating end for driving the pressure relief valve. The actuating end is provided with a contact slope, and the pressure relief valve has a mating slope for cooperating with the contact slope, so that the push rod pushes the pressure relief valve to float upward to open the pressure relief port.

[0022] In this solution, the push rod can directly cooperate with the pressure relief valve to drive the pressure relief valve, thereby simplifying the internal structure of the pot lid, saving space and cost. Through the cooperation of the contact slope and the mating slope, a part of the horizontal pushing force of the push rod can be converted into a vertical force, thereby pushing the pressure relief valve upward to open the pressure relief port.

[0023] The lid is also provided with a locking component at the opening end for locking with the pot body. The locking component is rotatably connected to the lid. The lid opening button cooperates with the locking component so as to drive the locking component to rotate and unlock the lid and the pot body.

[0024] In this design, the horizontal movement of the lid-opening button pushes the locking mechanism, causing it to rotate and thus loosening the latch of the locking mechanism from the pot body, thereby unlocking the lid and the pot body. At this point, the lid can be flipped upwards to open.

[0025] The lid is also equipped with a float valve and an exhaust port. The float valve can float up and down under the pressure of the air inside the pot, so as to have a blocking state when it floats up to block the exhaust port and a conducting state when it falls down to open the exhaust port. In the blocking state, the float valve cooperates with the locking stop to restrict the movement of the locking part.

[0026] In this design, when the pressure inside the pot exceeds atmospheric pressure, the float valve will float upwards under the pressure. At this point, the float valve and the locking mechanism will stop, preventing the locking mechanism from moving. Therefore, the user cannot press the lid-opening button, or even if the button is pressed, the locking mechanism cannot unlock from the pot. In other words, under high pressure inside the pot, the user cannot open the lid, thus ensuring the orderly and safe operation of pressure cooking and preventing accidental opening due to user error.

[0027] The pressure relief valve includes a first sealing part and a second sealing part located above the first sealing part. The first sealing part abuts against the pot lid to seal the pressure relief port. The second sealing part can move up and down to have a sealing state that presses the first sealing part and an unlocking state that is disengaged from the first sealing part. A push rod is used to drive the second sealing part to switch from the sealing state to the unlocking state.

[0028] In this design, the pressure relief valve consists of two parts, upper and lower. The upper second sealing part floats up and down under the drive of a push rod, preventing the push rod from directly opening the pressure relief port. Specifically, when the second sealing part is in a sealed state, pressing it against the first sealing part causes the first sealing part to block and seal the pressure relief port. Even under high pressure inside the pot, the first sealing part will firmly seal the pressure relief port due to the pressure from the second sealing part. When the push rod lifts the second sealing part, it separates from the first sealing part. Since the first sealing part is lighter, if the pressure inside the pot is still greater than atmospheric pressure, the first sealing part will be pushed upwards under the pressure, opening the pressure relief port to release air and pressure. After the pressure relief is complete, or when the pressure inside the pot equalizes with the external atmospheric pressure, the first sealing part falls back down to seal the pressure relief port again. This allows for switching between pressurized and atmospheric pressure cooking modes, enabling the cookware to perform both atmospheric and high-pressure cooking simultaneously. Specifically, when the second seal is in the sealed state, pressure cannot be released through the pressure relief valve unless the solenoid valve is activated, thus allowing for pressure cooking. When the second seal remains in the unlocked state, the gas inside the pot can be released promptly through the pressure relief port, allowing for cooking at atmospheric pressure.

[0050] like Figure 1 , Figure 2 As shown, a cooking appliance includes a pot body and a lid 1. The lid 1 has a connecting end 12 and an opening / closing end 11 arranged opposite to each other. The connecting end 12 is rotatably connected to the pot body. The opening / closing end 11 is provided with an opening button 2. The lid 1 is also provided with a solenoid valve 6, a driving component 3, and a pressure relief valve 7. The lid 1 has a pressure relief port 15. The pressure relief valve 7 blocks the pressure relief port 15. The solenoid valve 6 has a push rod 61. The driving component 3 is arranged between the opening button 2 and the solenoid valve 6. The driving component 3 has an operating end 31 that passes through the opening button 2 and protrudes for external tool operation. The driving component 3 can push the push rod 61 so that the push rod 61 drives the pressure relief valve 7 to move and open the pressure relief port 15.

[0051] It should be noted that this utility model does not limit the type of cooking appliance; it can be an electric pressure cooker, a low-pressure rice cooker, or other models that can perform pressure cooking at a pressure higher than the external atmospheric pressure.

[0052] like Figure 1 , Figure 2As shown, the connecting end 12 and the opening / closing end 11 are radially opposite each other along the lid 1. The connecting end 12 is rotatably connected to the pot body, and the opening / closing end 11 can be locked with the pot body. To open the lid, the user presses the lid-opening button 2 to unlock the opening / closing end 11 from the pot body, and then the lid can be opened by flipping it upwards. This method eliminates the need for the user to store the lid 1 separately, making it more convenient to use.

[0053] In this invention, the pot lid 1 is equipped with a solenoid valve 6, which is electrically connected to the control unit of the cooking appliance. Its push rod 61 is used to push the pressure relief valve 7 to open the pressure relief port 15, thereby achieving automatic pressure release. Under normal circumstances, after pressure cooking is completed, the push rod 61 of the solenoid valve 6 is controlled by the program to lift the pressure relief valve 7, opening the pressure relief port 15 for pressure release. Simultaneously, the pot lid 1 also has a partially exposed drive component 3, which drives the push rod 61, thus enabling manual pressure release. When the appliance is powered off during cooking, the user can operate the drive component 3 to drive the push rod 61 of the solenoid valve 6, causing the push rod 61 to lift the pressure relief valve 7, opening the pressure relief port 15 for pressure release. This integrates the functions of automatic and manual pressure relief in cooking appliances, with both pressure relief methods controlled by solenoid valve 6. Thus, the same component controls the pressure relief valve 7, eliminating the need for an additional drive mechanism for the pressure relief valve 7. This simplifies the structure of the lid 1, saves internal space, and reduces costs.

[0054] Furthermore, the operating end 31 of the drive component 3 passes through the lid-opening button 2 and is located externally, achieving positional integration of the drive component 3 and the lid-opening button 2. On the one hand, there is no need to create a separate space on the lid 1 for the drive component 3 or a manual venting structure, improving the simplicity of the lid 1's appearance and making user operation simpler and more convenient. On the other hand, since the operating end 31 of the drive component 3 and the lid-opening button 2 are in the same position, the lid-opening button 2 cannot be pressed when there is pressure inside the pot. The user can operate the drive component 3 independently, causing it to lift the pressure relief valve 7 via the push rod 61 to release pressure. Moreover, after normal pressure cooking is completed and the automatic pressure release is finished through program control, when the user opens the lid, they can simultaneously press the lid-opening button 2 and the drive component 3. As the lid 1 opens, the pressure relief valve 7 is lifted again, which helps to release residual gas inside the pot, ensuring safe opening and preventing the pressure inside the pot from rising again due to residual heat.

[0055] It should be noted that the present invention does not limit the location of the lid opening button 2 and the driving component 3. In one embodiment, the lid opening button 2 and / or the driving component 3 are located on the top surface of the pot lid 1, and the user can operate the lid opening button 2 and the driving component 3 by pressing down.

[0056] In another preferred embodiment, such as Figure 1 , Figure 2 As shown, the lid opening button 2 is located on the side of the pot lid 1, and the driving component 3 is arranged radially along the pot lid 1. Both the lid opening button 2 and the driving component 3 can move radially along the pot lid 1.

[0057] Both the lid-opening button 2 and the drive component 3 move radially along the lid 1. The user can press the lid-opening button 2 laterally from one side of the lid 1, or push the drive component 3. This ensures that their movement paths are identical, further simplifying user operation, and allows for simultaneous operation—that is, pressing both the lid-opening button 2 and the drive component 3 at the same time to simultaneously lift the pressure relief valve 7 during lid opening. Furthermore, it effectively saves space in the height direction of the lid 1, contributing to a thinner and lighter design.

[0058] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the driving component 3 is a driving rod that extends from the center of the lid-opening button 2. The user can directly push the operating end 31 of the driving component 3 with their hand to drive it, or they can drive it using the tools provided with the cooking appliance or other tools; this is not limited to these methods. Specifically, as... Figure 4 As shown, when the cover opening button 2 is not pressed, the driving end 81 of the driving component 3 can protrude from the surface of the cover opening button 2, or be flush with the surface of the cover opening button 2 or located inside the cover opening button 2. The user can use a tool to insert it into the mounting port of the cover opening button 2 to drive the driving component 3.

[0059] like Figure 1 As shown, the lid opening button 2, the drive component 3, the push rod 61, and the pressure relief valve 7 are all arranged in a collinear manner and are all located on the same diameter of the pot lid 1.

[0060] Preferably, such as Figure 1 , Figure 2 , Figure 4 As shown, the pot lid 1 is also provided with a button seat 4 fixed to the pot lid 1. The button seat 4 has a guide channel 41 extending radially along the pot lid 1 inside, and the lid opening button 2 is located inside the guide channel 41.

[0061] The lid opening button 2 is located in the guide channel 41 of the button base 4 and can slide back and forth along the extension direction of the guide channel 41. The guide channel 41 extends radially along the lid 1, which can restrict the movement path of the lid opening button 2 to the radial direction of the lid 1, making the movement of the lid opening button 2 more reliable and smooth, and reducing the probability of the lid opening button 2 getting stuck.

[0062] In a preferred embodiment, such as Figure 1 , Figure 4As shown, the driving component 3 also includes a driving part 33 and a linkage part 34. The driving part 33 is located between the cover opening button 2 and the button seat 4, and the linkage part 34 is located between the button seat 4 and the solenoid valve 6. An elastic reset member is sleeved on the outer periphery of the driving part 33. The elastic reset member is used to push the cover opening button 2 to move and reset.

[0063] When the user operates the control terminal 31, the drive unit 33 and the linkage unit 34 move synchronously, thereby driving the push rod 61 of the solenoid valve 6 through the linkage unit 34. The drive unit 33 is located between the cover opening button 2 and the button seat 4, and an elastic element 35 is sleeved on its exterior. The elastic element 35 can reset the drive unit 3. When the user presses the drive unit 3, the elastic element 35 is compressed. When the user stops pressing, the elastic element 35 pushes the drive unit 3 to reset. At the same time, the drive unit 33 can also limit the elastic element 35, so that the elastic element 35 can only deform along the axial direction, avoiding skewness and ensuring that the direction of application of the elastic force is stable and reliable.

[0064] It should be noted that this embodiment does not limit the assembly method of the driving part 33 and the linkage part 34. In one specific example, the driving part 33 and the linkage part 34 are an integral structure, and the button seat 4 has an opening for the linkage part 34 to pass through. In another specific example, such as Figure 4 As shown, the drive unit 33 and the linkage unit 34 are separate structures. The cover opening button 2 and the button base 4 are respectively provided with mounting holes for placing the drive unit 33. The linkage unit 34 is connected between the drive unit 33 and the push rod 61.

[0065] Preferably, the elastic element 35 is a spring, and the driving part 33 is provided with a limiting rib 32. One end of the elastic element 35 abuts against the button seat 4, and the other end abuts against the limiting rib 32, so as to push the driving part 3 to move and reset through its own elastic force.

[0066] This utility model does not limit the driving method of the push rod 61 to the pressure relief valve, which can be one of the following embodiments:

[0067] Implementation Method 1: In this implementation method, the push rod 61 indirectly drives the pressure relief valve. Specifically, as shown... Figure 1 , Figure 2 , Figure 3 As shown, the push rod 61 is arranged horizontally and has an actuating end 62 for driving the pressure relief valve 7. A transmission component 8 is provided between the actuating end 62 and the pressure relief valve 7. The transmission component 8 includes a driving end 81, a trigger end 82, and a connecting part 83 located between the driving end 81 and the trigger end 82. The connecting part 83 is rotatably connected to the pot lid 1. The actuating end 62 can horizontally push the driving end 81 to make the transmission component 8 rotate around the connecting part 83, so that the trigger end 82 lifts the pressure relief valve 7 to open the pressure relief port 15.

[0068] The push rod 61 of the solenoid valve 6 is arranged horizontally, which not only saves internal space of the pot lid 1, but also facilitates its cooperation with the lid opening button 2 and the drive component 3. A transmission component 8 is provided between the solenoid valve 6 and the pressure relief valve 7. The connecting part 83 of the transmission component 8 is rotatably connected to the pot lid 1, making the transmission component 8 a lever structure. When the actuating end 62 of the push rod 61 pushes the driving end 81 of the transmission component 8, the driving end 81 swings downward, causing the entire transmission component 8 to rotate around the connecting part 83. The trigger end 82 rises upward, thereby lifting the pressure relief valve 7 and opening the pressure relief port 15. The lever structure allows the push rod 61 to more easily lift the pressure relief valve 7 through the transmission component 8 by adjusting the lever arm length, thus making the operation more effortless for the user.

[0069] Of course, the transmission component 8 can also be configured as a sliding structure to drive the pressure relief valve by translation, which is not limited here.

[0070] Furthermore, such as Figure 2 , Figure 5 As shown, the drive end 81 is provided with a transmission inclined surface 811, and the action end 62 acts on the transmission inclined surface 811; the trigger end 82 is provided with a downwardly bent recessed section, which is used to cooperate with the pressure relief valve 7.

[0071] The transmission ramp 811 of the drive end 81 can convert a portion of the horizontal pushing force from the actuating end 62 into a vertically downward pressing force when pushed by the actuating end 62, thus allowing it to swing downward and causing the trigger end 82 to swing upward. The downwardly bent recessed section of the trigger end 82 cooperates with the pressure relief valve 7, which can reduce the space occupied in the height direction when the transmission component 8 moves, and also helps to reduce the height of the pressure relief valve 7, thereby saving space in the height direction of the lid 1.

[0072] Implementation Method 2: In this implementation method, the push rod 61 is arranged horizontally. The push rod 61 has an action end 62 for driving the pressure relief valve 7 to move. The action end 62 is provided with a contact slope. The pressure relief valve 7 has a mating slope for cooperating with the contact slope, so that the push rod 61 pushes the pressure relief valve 7 to float upward to open the pressure relief port 15.

[0073] The push rod 61 can directly cooperate with the pressure relief valve 7 to drive the pressure relief valve 7, thereby simplifying the internal structure of the pot lid 1, saving space and cost. Through the cooperation of the contact slope and the mating slope, a part of the horizontal pushing force of the push rod 61 can be converted into a vertical force, thereby pushing the pressure relief valve 7 upward to open the pressure relief port 15.

[0074] like Figure 3 As shown, a return spring is sleeved on the outer side of the push rod 61 at the end facing the drive member 3, which is used to drive the push rod 61 to move and return to its original position.

[0075] In a preferred embodiment, such as Figure 1 , Figure 4 As shown, the lid 1 is also provided with a locking member 5 at the opening end 11 for locking with the pot body. The locking member 5 is rotatably connected to the lid 1. The lid opening button 2 cooperates with the locking member 5 so as to drive the locking member 5 to rotate so that the lid 1 and the pot body can be unlocked.

[0076] The horizontal movement of the lid opening button 2 pushes the locking part 5, causing the locking part 5 to rotate, thereby loosening the hook of the locking part 5 from the pot body, thus unlocking the pot lid 1 and the pot body. At this time, the pot lid 1 can be flipped upward to open.

[0077] Specifically, such as Figure 4 As shown, the locking component 5 is vertically fixed to the pot lid 1. Its upper end is used to cooperate with the lid opening button 2, and its lower end is provided with a hook for locking with the pot body. The two ends are rotatably connected to the pot lid 1 through a rotating shaft. When the user presses the lid opening button 2, the lid opening button 2 pushes the top of the locking component 5 horizontally inward, causing the lower end of the locking component 5 to swing outward, loosening from the pot body and completing the unlocking.

[0078] Preferably, such as Figure 1 , Figure 2 As shown, the pot lid 1 is also equipped with a float valve 13 and an exhaust port 14. The float valve 13 can float up and down under the pressure of the air inside the pot body, so as to have a blocking state of floating up to block the exhaust port 14 and a conducting state of falling down to open the exhaust port 14. In the blocking state, the float valve 13 cooperates with the locking member 5 to stop and restrict the movement of the locking member 5.

[0079] When the pressure inside the pot is higher than atmospheric pressure, the float valve 13 will float upward under the pressure. At this time, the float valve 13 and the locking member 5 will stop, preventing the locking member 5 from moving. Therefore, the user cannot press the lid opening button 2, or even if the lid opening button 2 is pressed, the locking member 5 cannot be unlocked from the pot body. That is, under high pressure inside the pot, the user cannot open the lid, thus ensuring the orderly and safe operation of pressure cooking and preventing the lid from being opened due to user error.

[0080] It should be noted that, in one embodiment, after the float valve 13 stops and locks the locking member 5, the opening button 2 is also simultaneously restricted from moving, and the user cannot press the opening button 2 from the outside. In another embodiment, the opening button 2 can move relative to the locking member 5, so that after the float valve 13 stops and locks the member 5, the user can still press the opening button 2, but the opening button 2 cannot drive the locking member 5 to move.

[0081] Specifically, such as Figure 1 , Figure 2 As shown, the pot lid 1 is also equipped with a sliding member 9. When the lid opening button 2 is pressed, it pushes the locking member 5 to rotate. At the same time, the locking member 5 pushes the sliding member 9 to move. The float valve 13 can stop with the sliding member 9 in the blocking state, thereby restricting the movement of the locking member 5 and the lid opening button 2. Figure 1 As shown, the sliding member 9 forms an installation area within the pot lid 1, and the solenoid valve 6 is disposed within the installation area. The pot lid 1 is also provided with a pressure plate 16, which presses against the solenoid valve 6 to fix the solenoid valve 6.

[0082] This invention does not limit the structure of the pressure relief valve 7. In a preferred embodiment, such as... Figure 5 As shown, the pressure relief valve 7 includes a first sealing part 71 and a second sealing part 72 located above the first sealing part 71. The first sealing part 71 abuts against the pot lid 1 to seal the pressure relief port 15. The second sealing part 72 can move up and down to have a sealing state of pressing the first sealing part 71 and an unlocking state of disengaging from the first sealing part 71. The push rod 61 is used to drive the second sealing part 72 to switch from the sealing state to the unlocking state.

[0083] The pressure relief valve 7 is divided into upper and lower parts. The upper second sealing part 72 is driven by the push rod 61 to float up and down, thus preventing the push rod 61 from directly opening the pressure relief port 15. Specifically, when the second sealing part 72 is in a sealed state, it is pressed against the first sealing part 71. At this time, the first sealing part 71 blocks and seals the pressure relief port 15. Even if the pot is in a high-pressure environment, the first sealing part 71 will firmly seal the pressure relief port 15 due to the pressing force of the second sealing part 72. When the push rod 61 lifts the second sealing part 72, the second sealing part 72 separates from the first sealing part 71. At this time, because the first sealing part 71 is lighter, if the air pressure inside the pot is still greater than the atmospheric pressure, the first sealing part 71 will be pushed upward under the action of air pressure, opening the pressure relief port 15 to release pressure. After the pressure relief is completed, or when the air pressure inside the pot is balanced with the external atmospheric pressure, the first sealing part 71 falls down and seals the pressure relief port 15 again. This allows for switching between pressurized and atmospheric pressure cooking modes, enabling the cooking appliance to simultaneously perform both atmospheric pressure and high pressure cooking functions.

[0084] Specifically, when the second sealing part 72 is in the sealed state, pressure cannot be released through the pressure relief valve 7 unless the solenoid valve 6 is activated, thus pressure cooking is possible. When the second sealing part 72 remains in the unlocked state, the gas inside the pot can be released in time through the pressure relief port 15, at which point cooking can be carried out at atmospheric pressure.

[0085] like Figure 5 As shown, a sealing protrusion is provided at the lower end of the first sealing part 71, and the sealing protrusion extends into the pressure relief port 15. A first spring is provided on the outside of the first sealing part 71, and a second spring is provided on the outside of the second sealing part 72. The second spring is used to apply a downward force to the second sealing part 72. When the second sealing part 72 is lifted, the second spring is compressed. An elastic sealing element 73 is provided between the first sealing part 71 and the second sealing part 72.
