[0038] Please see Figure 1 and Figure 2 This utility model provides a cooking appliance including a lid assembly 100, a pot body (not shown), and a switching assembly 300. The lid assembly 100 includes a lid 101. The pot body is connected to the lid 101, and a cooking cavity is formed inside the pot body, which is covered by the lid assembly 100. The switching assembly 300 is disposed on the lid assembly 100 and includes an operating member 301 and a switching valve 302. The operating member 301 is connected to the switching valve 302, and the switching valve 302 has a steam vent 3021. The operating member 301 is configured to drive the switching valve 302 to close the steam vent 3021 to seal the cooking cavity, and to at least partially open the steam vent 3021 to connect the cooking cavity to the outside through the steam vent 3021.
[0039] The steam vent 3021 is configured such that when the steam vent 3021 is at least partially opened, the water in the cooking chamber can boil without overflowing and can maintain the set pressure.
[0040] In the aforementioned cooking appliance, when the switching valve 302 at least partially opens the vent 3021, it can maintain a certain pressure inside the cooking chamber, allowing the water to boil without overflowing, thereby enhancing the flavor of the soup to some extent. When the switching valve 302 closes the vent 3021, the cooking chamber is sealed, enabling pressure cooking.
[0041] Specifically, a cooking appliance is a cooking tool that improves cooking efficiency by utilizing the air pressure within a sealed container. Cooking appliances may include, but are not limited to, pressure cookers, electric pressure cookers, pressure slow cookers, etc.
[0042] The cooking appliance may include a lid assembly 100 and a pot body. When closed, the lid assembly 100 and the pot body fit tightly together via a sealing ring, forming a relatively enclosed cooking cavity. When the cooking appliance begins to operate, the food inside the cooking cavity is heated, water inside the cooking cavity begins to evaporate, and the amount of steam generated gradually increases, causing the pressure inside the cooking cavity to gradually rise. Because the cooking cavity is sealed at this time, the steam cannot escape from the cooking appliance, resulting in the pressure inside the cooking cavity being maintained, thereby raising the boiling point of the water and accelerating the cooking process. However, as the boiling point of the water increases, the boiling phenomenon is suppressed, which may affect the effect of making a rich and flavorful soup.
[0043] In related technologies, traditional electric pressure cookers achieve a rich broth primarily through an electromagnet pusher and solenoid valve structure that automatically and intermittently releases air, creating intermittent boiling and bubbling within the pot to produce a rich aroma. However, this method is costly, and the intermittent boiling has limited effect on achieving a rich broth flavor.
[0044] In this embodiment of the invention, the cooking appliance can operate in both a conventional pressure cooking mode and a rich aroma cooking mode. In the conventional pressure cooking mode, the operating element 301 is configured to drive the switching valve 302 to close the vent hole 3021, sealing the cooking chamber, thereby enabling conventional pressure cooking of the food. In the rich aroma cooking mode, the operating element 301 is configured to drive the switching valve 302 to at least partially open the vent hole 3021, connecting the cooking chamber to the outside environment through the vent hole 3021, thereby enabling rich aroma cooking of the food.
[0045] It should be noted that in conventional pressure cooking mode, the steam generated inside the cooking chamber cannot escape from the cooking appliance, and the pressure inside the cooking chamber is maintained, which raises the boiling point of water, that is, raises the cooking temperature inside the cooking chamber. This makes it easier to break down the cell structure of the food, making the food softer or cooked through faster.
[0046] In the rich aroma cooking mode, the steam vent 3021 can be at least partially opened by the operating component 301. The steam generated in the cooking chamber can be discharged to the outside of the cooking chamber through the steam vent 3021. The steam vent area of the steam vent 3021 can reduce the pressure in the cooking chamber, thereby reducing the boiling point of the water in the cooking chamber to a certain extent, allowing the water to continue boiling and improving the rich aroma soup effect. At the same time, the steam vent area of the steam vent 3021 can ensure that the pressure in the cooking chamber is still greater than the atmospheric pressure, so that the boiling point of the water is higher than 100℃ and does not overflow outside the cooking chamber. That is, the cooking temperature in the cooking chamber is higher than 100℃, thereby ensuring the cooking efficiency of the cooking appliance to a certain extent.
[0047] Optionally, in one embodiment, the venting area of the vent 3021 can effectively reduce the boiling point of water, thereby effectively improving the duration of water boiling and enhancing the flavor of the soup. At the same time, even when the vent 3021 is partially open, the pressure inside the cooking chamber is greater than 4 kPa, meaning that the pressure inside the cooking chamber is still greater than atmospheric pressure when the cooking appliance is working, ensuring that the boiling point of water is above 100°C and does not overflow from the cooking chamber, thus guaranteeing cooking efficiency to a certain extent.
[0048] Optionally, in one embodiment, the venting area of the vent 3021 can effectively reduce the boiling point of water, thereby effectively improving the duration of water boiling and enhancing the flavor of the soup. At the same time, it can ensure that the pressure inside the cooking chamber is greater than 4 kPa when the vent 3021 is fully open. That is, the pressure inside the cooking chamber is still greater than atmospheric pressure when the cooking appliance is working, so that the boiling point of water is higher than 100°C and does not overflow outside the cooking chamber, thereby ensuring cooking efficiency to a certain extent.
[0049] When the vent hole 3021 is at least partially open, the water in the cooking chamber can boil without overflowing and maintain the set pressure. The vent area of the vent hole 3021 is related to the volume of the cooking chamber. The aperture of the vent hole 3021 for different cooking chamber volumes can be calibrated by simulation, testing and other methods so that when the vent hole 3021 is at least partially open, the water in the cooking chamber can boil without overflowing and maintain the set pressure (e.g., 5 kPa).
[0050] Optionally, in one embodiment, the volume of the cooking cavity is less than or equal to 5 liters (L). Correspondingly, the diameter of the vent 3021 is greater than or equal to 1 mm, which can effectively lower the boiling point of water, thereby effectively improving the duration of boiling and enhancing the flavor of the soup. Simultaneously, the diameter of the vent 3021 is less than or equal to 2 mm, ensuring that the pressure inside the cooking cavity is greater than 4 kPa when the vent 3021 is fully open. This means that the pressure inside the cooking cavity remains greater than atmospheric pressure even when the cooking appliance is operating, keeping the boiling point of water above 100°C and preventing it from overflowing the cooking cavity, thus ensuring cooking efficiency to a certain extent. Optionally, the volume of the cooking cavity refers to the maximum volume marked on the volume scale line on the inner wall of the cooking cavity.
[0051] Optionally, in one embodiment, the diameter of the vent hole 3021 is greater than 2mm, which can effectively lower the boiling point of water, thereby effectively improving the continuity of water boiling and thus enhancing the flavor of soup. At the same time, even when the vent hole 3021 is partially opened, the pressure inside the cooking chamber is greater than 4KPa, that is, the pressure inside the cooking chamber is still greater than atmospheric pressure when the cooking appliance is working, so that the boiling point of water is higher than 100℃ and does not overflow outside the cooking chamber, thereby ensuring cooking efficiency to a certain extent.
[0052] Optionally, in one embodiment, the diameter of the vent 3021 is greater than 2mm, which can effectively lower the boiling point of water, thereby effectively improving the continuity of water boiling and thus enhancing the flavor of soup. At the same time, it can ensure that the pressure inside the cooking chamber is greater than 4KPa when the vent 3021 is fully open. That is, the pressure inside the cooking chamber is still greater than atmospheric pressure when the cooking appliance is working, so that the boiling point of water is higher than 100℃ and does not overflow outside the cooking chamber, thereby ensuring cooking efficiency to a certain extent.
[0053] In some examples, the exhaust port 3021 is a circular hole with a diameter S of 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, or other values that satisfy 1 mm ≤ S ≤ 2 mm.
[0054] Optionally, the number, size, and shape of each vent hole 3021 can be selected according to the volume of the cooking chamber or other requirements, ensuring that the water in the cooking chamber can boil without overflowing and maintain the set pressure when the vent hole 3021 is at least partially open. For example, if the switching valve 302 has a single vent hole 3021, the water in the cooking chamber can boil without overflowing and maintain the set pressure when the single vent hole 3021 is at least partially open. If the switching valve 302 has multiple vent holes 3021, the water in the cooking chamber can boil without overflowing and maintain the set pressure when all vent holes 3021 are at least partially open. The venting areas of the multiple vent holes can be the same or different.
[0055] In one example, the pressure setting could be 5 kPa. Under normal pressure mode, the pressure inside the cooking cavity could be 6 kPa.
[0056] In some implementations, please refer to Figure 1 and Figure 2 The switching component 300 includes a push rod 303, and the operating element 301 is connected to the switching valve 302 via the push rod 303.
[0057] In the above embodiment, the operating element 301 can be connected to the switching valve 302 via the push rod 303. This allows the operating element 301 to drive the switching valve 302 to at least partially open and close the vent hole 3021. Therefore, when the switching valve 302 at least partially opens the vent hole 3021, the effect of simmering soup with rich aroma is enhanced to some extent. When the switching valve 302 closes the vent hole 3021, the cooking chamber is sealed, which improves cooking efficiency to some extent.
[0058] Specifically, push rod 303 is a mechanical component that can be used to transmit force and motion. Actuator 301 can drive switching valve 302 to at least partially open and close vent port 3021 via push rod 303.
[0059] Optionally, in one embodiment, the operating component 301 can be connected to the push rod 303 by means of welding, bonding, thread fastening, snap-fit, etc. In one embodiment, the operating component 301 and the push rod 303 can be an integrally formed structure.
[0060] In some implementations, please refer to Figure 1 and Figure 2 The push rod 303 includes a first part 3031 and a second part 3032. The operating member 301 can drive the push rod 303 to move so that the first part 3031 drives the switching valve 302 to close the exhaust port 3021, and causes the second part 3032 to drive the switching valve 302 to at least partially open the exhaust port 3021.
[0061] In the above embodiment, the operating member 301 can drive the push rod 303 to move, causing the first part 3031 to drive the switching valve 302 to close the vent hole 3021, and causing the second part 3032 to drive the switching valve 302 to at least partially open the vent hole 3021. This improves the flavor of the soup to a certain extent when the switching valve 302 at least partially opens the vent hole 3021. When the switching valve 302 closes the vent hole 3021, it seals the cooking chamber, thus improving cooking efficiency to a certain extent.
[0062] Specifically, the first part 3031 can drive the switching valve 302 to close the exhaust port 3021, and the second part 3032 can drive the switching valve 302 to at least partially open the exhaust port 3021.
[0063] In one embodiment, when the operating member 301 moves in the first direction, it drives the push rod 303 to move in the first direction, thereby causing the first part 3031 to drive the switching valve 302 to close the exhaust port 3021.
[0064] In one embodiment, when the operating member 301 moves in the second direction, it drives the push rod 303 to move in the second direction, thereby causing the second part 3032 to drive the switching valve 302 to at least partially open the exhaust port 3021.
[0065] In some implementations, please refer to Figure 1 and Figure 2 The push rod 303 includes a connecting part 3033. The operating member 301 is connected to the switching valve 302 in sequence through the connecting part 3033, the first part 3031 and the second part 3032. In the height direction of the cooking appliance, the connecting part 3033 is located above the second part 3032. The first part 3031 is inclined and connects the second part 3032 and the connecting part 3033.
[0066] In the above embodiment, the connecting part 3033 is located above the second part 3032, and the first part 3031 is inclined and connects the second part 3032 and the connecting part 3033, which helps the operating member 301 to drive the switching valve 302 to at least partially open and close the exhaust port 3021.
[0067] Specifically, the projections of the connecting part 3033, the first part 3031, and the second part 3032 in the height direction of the cooking utensil do not overlap.
[0068] In one embodiment, the operating member 301 moves along the first direction, and the connecting part 3033 drives the first part 3031 and the second part 3032 to move along the first direction. At this time, the inclined first part 3031 can lift the switching valve 302, thereby causing the steam vent 3021 located on the switching valve 302 to exit the cooking chamber, that is, to close the steam vent 3021.
[0069] In one embodiment, the operating member 301 moves along the second direction, and the connecting part 3033 drives the first part 3031 and the second part 3032 to move along the second direction. At this time, the second part 3032 can press down the switching valve 302, so that the steam vent 3021 located on the switching valve 302 enters the cooking chamber, that is, the steam vent 3021 is at least partially opened.
[0070] Optionally, in one embodiment, the operating member 301, the connecting part 3033, the first part 3031 and the second part 3032 can be connected by welding, bonding, thread fastening, snap fastening or other means. In one embodiment, at least two of the operating member 301, the connecting part 3033, the first part 3031 and the second part 3032 can be integrally formed structures.
[0071] In some implementations, please refer to Figures 1 to 2 The pot lid assembly 100 includes a rotating rod 105, a first detection element 106, and a second detection element 107. The rotating rod 105 is connected to a push rod 303. The first detection element 106 is disposed on the rotating rod 105, and the second detection element 107 is disposed on the pot lid 101. The second detection element 107 is used to determine whether the vent hole 3021 is at least partially open or closed by detecting the position of the first detection element 106.
[0072] In the above embodiment, the second detection element 107 determines whether the vent hole 3021 is at least partially open or closed by detecting the position of the first detection element 106, thereby determining the sealing state of the cooking cavity, which is beneficial for the cooking appliance to work in the correct cooking mode.
[0073] Specifically, in the normal pressure cooking mode, the first detection element 106 moves away from the second detection element 107. At this time, the switching valve 302 is lifted, thereby causing the vent 3021 to exit the cooking chamber and the vent 3021 to be closed.
[0074] In the rich aroma cooking mode, the first detection element 106 approaches or aligns with the second detection element 107. At this time, the switching valve 302 is pressed down, causing the vent hole 3021 to extend into the cooking chamber, and the vent hole 3021 is at least partially opened.
[0075] It is understandable that the operating component 301 can drive the rotating rod 105 to move. The movement of the rotating rod 105 includes, but is not limited to, translation, rotation, and oscillation. Figures 1 to 2 In the embodiment shown, the rotating rod 105 moves by rotation.
[0076] In one embodiment, when the operating member 301 moves along the first direction, it can drive the push rod 303 to move along the first direction, and simultaneously drive the rotating rod 105 to rotate in a direction away from the second detection member 107, so that the first detection member 106 and the second detection member 107 move away from each other. When the operating member 301 moves along the second direction, it can drive the push rod 303 to move in the second direction, and simultaneously drive the rotating rod 105 to rotate in a direction close to the second detection member 107, so that the first detection member 106 and the second detection member 107 move closer to each other or are aligned.
[0077] In one embodiment, the second detection element 107 may include a magnetic switch (reed switch), and the first detection element 106 may include a magnetic element (magnet), the magnetic switch being used to sense the position of the magnet. In one embodiment, the first detection element 106 may include a bump, and the second detection element 107 may include a micro switch, the bump being used to trigger the micro switch. In one embodiment, the first detection element 106 may include a light emitter, and the second detection element 107 may include a light receiver, the light receiver being used to receive light emitted by the light emitter to determine the position of the first detection element 106.
[0078] In some implementations, please refer to Figure 2 The switching valve 302 is provided with a first sealing element 102 at the first end inside the cooking cavity. The switching valve 302 passes through the pot lid 101. When the switching valve 302 closes the steam vent 3021, the first sealing element 102 abuts against the pot lid 101 inside the cooking cavity to seal the gap between the switching valve 302 and the pot lid 101.
[0079] In the above embodiments, the first sealing member 102 can seal the gap between the pot lid 101 and the switching valve 302 when the switching valve 302 closes the steam vent 3021, preventing steam in the cooking chamber from escaping out of the cooking chamber and ensuring the cooking efficiency of the cooking appliance to a certain extent.
[0080] Specifically, when the switching valve 302 closes the vent 3021, that is, when the vent 3021 exits the cooking chamber, the first end of the switching valve 302 partially exits the cooking chamber, and at the same time, the first sealing member 102 provided at the first end can abut against the pot lid 101 to seal the gap between the switching valve 302 and the pot lid 101.
[0081] exist Figure 2In this embodiment, a first receiving groove 3023 is provided at the first end, and the first sealing member 102 may include a first body portion 1021 and a first sealing portion 1022. The first body portion 1021 may be sleeved on the first end of the switching valve 302 and received in the first receiving groove 3023 to limit the relative position between the first sealing member 102 and the switching valve 302, which is beneficial to effectively seal the gap between the switching valve 302 and the pot lid 101 when the switching valve 302 closes the vent hole 3021. When the switching valve 302 closes the vent hole 3021, the first sealing portion 1022 abuts against the pot lid 101 to seal the gap between the switching valve 302 and the pot lid 101.
[0082] In some implementations, please refer to Figure 2 The steam vent 3021 is located above the first seal 102. The operating component 301 drives the switching valve 302 to move upward, causing the steam vent 3021 to exit the cooking chamber and the first seal 102 to abut against the pot lid 101.
[0083] The operating component 301 drives the switching valve 302 to move downward, causing the steam vent 3021 to enter the cooking chamber and the first seal 102 to separate from the pot lid 101.
[0084] In the above embodiment, the steam vent 3021 is located above the first seal 102, which can effectively seal the gap between the pot lid 101 and the switching valve 302 when the first seal 102 closes the steam vent 3021, preventing steam in the cooking chamber from escaping out of the cooking chamber and ensuring the cooking efficiency of the cooking appliance to a certain extent.
[0085] Specifically, the operating component 301 moves along the first direction, causing the push rod 303 to move along the first direction. At this time, the inclined first part 3031 can push up the switching valve 302, causing it to move upward. The vent hole 3021 on the switching valve 302 exits the cooking chamber, that is, the vent hole 3021 is closed. At the same time, the first sealing component 102 located below the vent hole 3021 moves upward along with the switching valve 302 and abuts against the pot lid 101, thereby sealing the gap between the pot lid 101 and the switching valve 302.
[0086] When the operating component 301 moves in the second direction, it drives the push rod 303 to move in the second direction. At this time, the inclined second part 3032 can press down the switching valve 302, causing it to move downward. The vent hole 3021 on the switching valve 302 enters the cooking chamber, that is, the vent hole 3021 is at least partially opened. At the same time, the first sealing member 102 located below the vent hole 3021 moves downward along with the switching valve 302 and separates from the pot lid 101.
[0087] In some implementations, please refer to Figure 2The switching valve 302 is provided with a second sealing element 103 located outside the cooking cavity. The switching valve 302 passes through the pot lid 101. When the switching valve 302 at least partially opens the steam vent 3021, the second sealing element 103 abuts against the pot lid 101 outside the cooking cavity to seal the gap between the switching valve 302 and the pot lid 101.
[0088] In the above embodiments, the second seal 103 can seal the gap between the pot lid 101 and the switching valve 302 when the switching valve 302 at least partially opens the steam vent 3021, preventing steam in the cooking chamber from escaping out of the cooking chamber through the gap between the pot lid 101 and the switching valve 302, and to a certain extent ensuring that steam is discharged out of the cooking chamber through the steam vent 3021, thereby ensuring that a certain pressure is maintained in the cooking chamber and ensuring the cooking efficiency of the cooking appliance.
[0089] Specifically, when the switching valve 302 at least partially opens the vent 3021, that is, when the vent 3021 enters the cooking chamber, the second seal 103 on the switching valve 302 located outside the cooking chamber can abut against the pot lid 101 to seal the gap between the switching valve 302 and the pot lid 101.
[0090] exist Figure 2 In this embodiment, the switching valve 302 is provided with a second receiving groove 3024 located outside the cooking cavity, and the second sealing member 103 may include a second body portion 1031 and a second sealing portion 1032. The second body portion 1031 may be sleeved on the switching valve 302 and received in the second receiving groove 3024 to limit the relative position between the second sealing member 103 and the switching valve 302, which is beneficial to effectively seal the gap between the switching valve 302 and the pot lid 101 when the switching valve 302 at least partially opens the vent hole 3021. When the switching valve 302 at least partially opens the vent hole 3021, the second sealing portion 1032 abuts against the pot lid 101 to seal the gap between the switching valve 302 and the pot lid 101.
[0091] In some implementations, please refer to Figure 2 The steam vent 3021 is located below the second seal 103. The operating component 301 drives the switching valve 302 to move upward, causing the steam vent 3021 to exit the cooking chamber and the second seal 103 to separate from the pot lid 101.
[0092] The operating component 301 drives the switching valve 302 to move downward, causing the steam vent 3021 to enter the cooking chamber and the second sealing component 103 to abut against the pot lid 101.
[0093] In the above embodiment, the steam vent 3021 is located below the first seal 102, which can effectively achieve the second seal 103 sealing the gap between the pot lid 101 and the switching valve 302 when the switching valve 302 at least partially opens the steam vent 3021, preventing steam in the cooking chamber from escaping out of the cooking chamber through the gap between the pot lid 101 and the switching valve 302, and to a certain extent ensuring that steam is discharged out of the cooking chamber through the steam vent 3021, thereby ensuring that a certain pressure is maintained in the cooking chamber and ensuring the cooking efficiency of the cooking appliance.
[0094] Specifically, the operating component 301 moves along the first direction, causing the push rod 303 to move along the first direction. At this time, the inclined first part 3031 can lift the switching valve 302, causing it to move upward. The vent hole 3021 on the switching valve 302 exits the cooking chamber, that is, the vent hole 3021 is closed. At the same time, the second sealing component 103 located above the vent hole 3021 moves upward along with the switching valve 302 and separates from the pot lid 101.
[0095] When the operating component 301 moves in the second direction, it drives the push rod 303 to move in the second direction. At this time, the inclined second part 3032 can press down the switching valve 302, causing it to move downward. The vent hole 3021 on the switching valve 302 enters the cooking chamber, that is, the vent hole 3021 is at least partially opened. At the same time, the second sealing component 103 located above the vent hole 3021 moves downward together with the switching valve 302 and abuts against the pot lid 101, thereby sealing the gap between the pot lid 101 and the switching valve 302.
[0096] It should be noted that, in Figures 1 to 2 In the implementation of the method, the first direction is the direction in which the push rod 303 approaches the switching valve 302, and the second direction is the direction in which the push rod 303 moves away from the switching valve 302.
[0097] The movement of the operating component 301 includes, but is not limited to, translation, rotation, and oscillation. Figure 1 In the embodiment shown, the movement of the operating member 301 is translation.
[0098] In some implementations, please refer to Figure 2 The switching valve 302 is provided with a steam exhaust channel 3022, which is connected to the steam exhaust hole 3021;
[0099] When the switching valve 302 at least partially opens the vent hole 3021, the vent passage 3022 is connected to the cooking chamber through the vent hole 3021.
[0100] In the above embodiments, when the switching valve 302 at least partially opens the steam vent 3021, the steam venting channel 3022 is connected to the cooking chamber through the steam vent 3021, thereby effectively venting the steam in the cooking chamber from the steam vent 3021 and the steam venting channel 3022 to the outside of the cooking chamber, maintaining a certain pressure in the cooking chamber, and ensuring that the water boils but does not overflow, thereby improving the effect of making rich and fragrant soup to a certain extent.
[0101] Specifically, the exhaust passage 3022 is connected to the outside of the cooking appliance. When the switching valve 302 at least partially opens the exhaust port 3021, the exhaust port 3021 is connected to the cooking chamber, and at the same time, the exhaust passage 3022 is connected to the exhaust port 3021, thereby enabling the cooking chamber to be connected to the outside of the cooking appliance and effectively venting the steam in the cooking chamber to the outside of the cooking appliance.
[0102] In some implementations, please refer to Figure 2 At least one exhaust port 3021 is provided on the wall of the exhaust passage 3022.
[0103] In the above embodiment, at least one steam vent 3021 is provided on the wall of the steam vent channel 3022. When the switching valve 302 at least partially opens the steam vent 3021, the steam vent channel 3022 is connected to the cooking chamber through the steam vent 3021. Thus, when the switching valve 302 at least partially opens the steam vent 3021, the steam in the cooking chamber is effectively discharged from the steam vent 3021 and the steam vent channel 3022 to the outside of the cooking chamber, so that the cooking chamber maintains a certain pressure and the water can boil but not overflow, thereby improving the effect of making rich and fragrant soup to a certain extent.
[0104] Specifically, when the switching valve 302 at least partially opens the vent hole 3021, the steam in the cooking chamber flows from the vent hole 3021 into the exhaust port, and then flows out of the cooking chamber through the exhaust channel 3022.
[0105] In some implementations, please refer to Figure 2 The pot lid assembly 100 includes a mounting base 104. The pot lid 101 is provided with a mounting hole. The mounting base 104 is fixed in the mounting hole. The switching valve 302 can be movably inserted through the mounting base 104.
[0106] In the above embodiments, the mounting base 104 is fixed in the mounting hole, and the switching valve 302 can be movably inserted through the mounting base 104, which can make the switching valve 302 more securely installed on the pot lid 101, and to a certain extent extend the service life of the switching valve 302.
[0107] Specifically, the mounting hole is an opening on the pot lid 101, and the switching valve 302 can be movably inserted through the mounting base 104 and the mounting hole, partially entering the cooking cavity.
[0108] When the operating element 301 drives the switching valve 302 to at least partially open the vent hole 3021, the switching valve 302 moves downward so that the vent hole 3021 extends into the cooking chamber. The second sealing element 103 located on the switching valve 302 outside the cooking chamber can abut against the mounting seat 104 to seal the gap between the mounting seat 104 and the pot lid 101.
[0109] When the operating element 301 drives the switching valve 302 to close the vent hole 3021, the switching valve 302 moves upward to make the vent hole 3021 exit the cooking chamber. The first sealing element 102 located at the first end of the switching valve 302 can abut against the mounting base 104 to seal the gap between the mounting base 104 and the pot lid 101.
[0110] Optionally, the mounting base 104 can be fixed to the mounting hole by welding, bonding, threading, snap-fitting, or other means. The pot lid assembly 100 may include a third seal, which is disposed on the mounting base 104 and abuts against the pot lid 101 to seal the gap between the mounting base 104 and the pot lid 101.
[0111] In some implementations, please refer to Figure 1 The cooking appliance includes a venting assembly 400, which includes a venting valve 401 and a pressure relief passage 402. The pressure relief passage 402 is connected to the cooking chamber. The venting valve 401 is used to at least partially open the pressure relief passage 402 to connect the cooking chamber to the outside when the pressure in the cooking chamber is greater than the set pressure, and to close the pressure relief passage 402 to seal the cooking chamber when the pressure in the cooking chamber is less than or equal to the set pressure.
[0112] In the above embodiments, the exhaust valve 401 is used to at least partially open the pressure relief channel 402 to connect the cooking chamber with the outside when the pressure inside the cooking chamber is greater than the set pressure, which can reduce the safety hazards of the cooking appliance to a certain extent. At the same time, when the pressure inside the cooking chamber is less than or equal to the set pressure, the pressure relief channel 402 is closed to seal the cooking chamber, which can maintain the air pressure inside the cooking chamber and ensure the cooking efficiency of the cooking appliance to a certain extent.
[0113] Specifically, the pot lid 101 has a through hole that connects to the cooking chamber, and the exhaust valve 401 covers the through hole. When the pressure inside the cooking chamber exceeds the set pressure, the exhaust valve 401 is pushed up by the air pressure inside the cooking chamber against gravity. At this time, the pressure relief channel 402 is at least partially opened, connecting the cooking chamber to the outside. This allows the steam inside the cooking chamber to be effectively discharged to the outside, preventing excessive pressure inside the cooking chamber from increasing safety hazards.
[0114] When the pressure inside the cooking chamber is less than or equal to the set pressure, the exhaust valve 401 closes the pressure relief channel 402 under the action of gravity, thus sealing the cooking chamber and maintaining the air pressure inside the cooking chamber, thereby ensuring the cooking efficiency of the cooking appliance to a certain extent.
[0115] In some implementations, please refer to Figure 1 The cooking utensil includes a float 500, which can be raised and lowered to hold the pot lid 101.
[0116] In the above embodiment, the float 500 can be raised and lowered through the pot lid 101, thereby reflecting the pressure changes inside the cooking cavity in real time.
[0117] Specifically, when the pressure inside the cooking cavity increases (greater than atmospheric pressure), the float 500 will rise accordingly; when the pressure inside the cooking cavity decreases (equal to atmospheric pressure), the float 500 will fall accordingly.
