Description

Technical Field

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

[0002] Pressure cookers (such as electric pressure cookers) are common cooking appliances in household kitchens. However, electric pressure cookers can usually only perform pressure cooking and cannot perform atmospheric pressure cooking. If users want to use atmospheric pressure cooking, they can only purchase an atmospheric pressure rice cooker or other cooking appliances separately.

[0003] In recent years, a multi-functional cooking appliance has emerged that can perform both pressure cooking (used as an electric pressure cooker) and atmospheric pressure cooking (used as a regular rice cooker), integrating both functions into one machine and significantly improving the user experience. The working principle of this multi-functional cooking appliance is as follows: a pressure switching device is installed on the lid. By controlling the opening and closing of this device, the cooking mode is switched. Specifically, when the inside of the pot is connected to the outside through the pressure switching device, it is in atmospheric pressure cooking mode. In this mode, the inside and outside of the pot remain connected, thus achieving atmospheric pressure cooking. When the pressure switching device is closed, it is in pressure cooking mode, allowing pressure to build up inside the pot during cooking, achieving pressure cooking.

[0004] Meanwhile, the pot lid is also equipped with a pressure relief valve for venting and releasing pressure. Therefore, the pot lid has two devices for venting: a pressure switching device and a pressure relief valve. Some cooking appliances also have a noise-reducing box on the pot lid to reduce the noise of the pressure relief valve, with the noise-reducing box covering the pressure relief valve. However, the pressure switching device also needs noise reduction. If both the pressure relief valve and the pressure switching device are simply enclosed inside the noise-reducing box, sharing the same cavity for venting, then when the pressure relief valve releases air, some of the airflow and liquid such as rice water will be blocked by the ribs inside the noise-reducing box, and some of the airflow and liquid will enter the pot lid through the pressure switching device. This will not only cause contamination of the inside of the pot lid, leading to an unpleasant odor over time, but also cause the pressure switching device to become clogged, resulting in malfunction. Utility Model Content

[0005] This utility model provides a cooking appliance to solve the problems of excessive noise and large steam emission during the exhaust process of the pressure switching device, as well as the problem that when the pressure switching device and the pressure relief valve are covered by a noise reduction box, they share one cavity inside the noise reduction box for exhaust, which makes it easy for soup to enter the pot lid through the pressure switching device and cause the valve of the pressure switching device to stick together.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A cooking appliance includes a pot body, a pot lid, and a venting box disposed on the pot lid. The pot lid is provided with a venting valve and a pressure conversion valve. The pressure conversion valve has an open state and a closed state. The venting box has a first venting chamber and a second venting chamber that are separated from each other. The first venting chamber is connected to the venting valve, and the second venting chamber is connected to the pressure conversion valve. The venting box has a first venting port that connects to the first venting chamber and a second venting port that connects to the second venting chamber.

[0008] In this invention, the pressure conversion valve has an open state and a closed state, thus enabling the cooking appliance to have both atmospheric pressure cooking mode and high pressure cooking mode. In atmospheric pressure cooking mode, the cooking chamber is connected to the outside atmosphere through the pressure conversion valve, and the pot remains at atmospheric pressure throughout the cooking process. In high pressure cooking mode, the cooking chamber is isolated from the outside environment at the pressure conversion valve, so that after the float is raised, the cooking chamber is completely isolated from the outside environment, and pressure can be applied inside the cooking chamber for high-pressure cooking.

[0009] The vent box contains a first vent chamber connected to the vent valve and a second vent chamber connected to the pressure conversion valve. These two chambers are separated, preventing the airflow from the vent valve and pressure conversion valve from mixing and ensuring their respective venting efficiency. This avoids turbulence caused by collisions between the two airflows, which can generate noise and affect venting efficiency. Furthermore, the airflow and liquid ejected from the vent valve can only flow within the first vent chamber and cannot enter the second vent chamber, thus preventing them from reaching the pressure conversion valve and entering the lid. This prevents hot air from flowing back into the lid, causing it to overheat and providing a better tactile experience for the user. It also prevents thick soup overflowing from the vent valve from flowing to the pressure conversion valve and causing it to stick, ensuring the pressure conversion valve remains unobstructed.

[0010] The bottom wall of the first exhaust chamber is provided with a first pair of interfaces that connect with the exhaust valve, and a first water collection tank surrounding the first pair of interfaces. The bottom wall of the second exhaust chamber is provided with a second pair of interfaces that connect with the pressure conversion valve, and a second water collection tank surrounding the second pair of interfaces.

[0011] In this design, the first pair of interfaces connects to the exhaust valve, allowing the airflow from the exhaust valve to enter the first exhaust chamber. The second pair of interfaces connects to the pressure switching valve, allowing the airflow from the pressure switching valve to enter the second exhaust chamber. A first water collection tank is located around the outer periphery of the first pair of interfaces, and a second water collection tank is located around the outer periphery of the second pair of interfaces. During the exhaust process, some steam in the two exhaust chambers comes into contact with the inner walls of the two chambers, forming condensate. This condensate then flows back or drips into the first and second water collection tanks, facilitating centralized cleaning by the user and preventing condensate from flowing back into the pot lid.

[0012] Both the first pair of interfaces and the second pair of interfaces have ribs extending toward the interior of the exhaust box on their outer periphery, so as to form a first water collection trough and a second water collection trough on the outside of the ribs.

[0013] In this design, the retaining ribs extend inward toward the vent box and surround the outer periphery of the first and second pairs of interfaces, so that the upper edge of the retaining ribs is higher than the outer areas of the first and second pairs of interfaces. This naturally forms a groove structure on the outer side of the retaining ribs for collecting condensate and other liquids. At the same time, the retaining ribs also act as a barrier to prevent liquids in the first and second water collection tanks from flowing to the first and second pairs of interfaces, further reducing the risk of liquid backflow into the pot lid.

[0014] The first exhaust port is located on the top wall of the first exhaust chamber and is vertically aligned with the first water collection tank. The second exhaust port is located on the top wall of the second exhaust chamber and is vertically aligned with the second water collection tank.

[0015] In this design, the first exhaust port and the first pair of interfaces are vertically offset, as are the second exhaust port and the second pair of interfaces. This lengthens the airflow path within the first and second exhaust chambers, helping to reduce the kinetic energy of the airflow and thus achieving noise reduction and gas-liquid separation. Simultaneously, the first exhaust port and the first water collection tank are vertically aligned, and the second exhaust port and the second water collection tank are vertically aligned. This ensures that when the steam flowing to the first and second exhaust ports condenses into water upon cooling, it can drip directly into the first and second water collection tanks, guaranteeing their effective collection of condensate.

[0016] The bottom wall of the first exhaust chamber is provided with a first pair of interfaces that connect with the exhaust valve, and the bottom wall of the second exhaust chamber is provided with a second pair of interfaces that connect with the pressure conversion valve. A baffle is provided between the first pair of interfaces and the second pair of interfaces to separate the first exhaust chamber and the second exhaust chamber.

[0017] In this design, the baffles located between the first pair of interfaces and the second pair of interfaces separate the first exhaust chamber and the second exhaust chamber, while ensuring that the first pair of interfaces and the second pair of interfaces are located in the two exhaust chambers respectively. The airflow discharged from the pressure switching valve and the exhaust valve flows and discharges in their respective chambers without mixing. At the same time, the condensate formed by steam liquefaction, as well as the liquid and foam that rise with the airflow, are also collected in their respective chambers.

[0018] The exhaust box includes a base and a cover, and the baffle includes a first baffle disposed on the base and extending toward the cover; and / or, the baffle includes a second baffle disposed on the base and extending toward the cover.

[0019] In this design, a first baffle rib is provided on the base, extending upwards and abutting against the cover to separate the first exhaust chamber and the second exhaust chamber. Alternatively, a second baffle rib extending downwards can be provided on the cover to abut against the base and separate the first exhaust chamber and the second exhaust chamber. Similarly, a first baffle rib can be provided on the base, and a second baffle rib can be provided on the cover, with the first and second baffle ribs working together to separate the first exhaust chamber and the second exhaust chamber.

[0020] The vent box includes a base and a lid. The base is detachably mounted on the pot lid, and the lid can move relative to the base to open or close the base.

[0021] In this design, the cover can move relative to the base to open the exhaust box, fully exposing its internal structure. Users can then clean the internal interfaces and the liquid collected inside the exhaust box. This simplifies cleaning the exhaust box and improves the user experience.

[0022] The cover has a connecting end and a locking end that are arranged opposite to each other. The connecting end is rotatably connected to the base, and the locking end can be locked or unlocked with the base so that the cover can be flipped around the connecting end.

[0023] In this design, by rotatably connecting one end of the cover to the base, the cover can be flipped up and down around the connecting end to close or open the base, thus fully opening the base for thorough cleaning of the exhaust box. The opening and closing operation is also simple and user-friendly. Furthermore, since one end of the cover remains connected to the base at all times, it eliminates the hassle of storing the cover when open, effectively preventing its loss.

[0024] Diverting ribs are provided at the first and second exhaust ports, which divide the first and second exhaust ports into multiple exhaust channels.

[0025] In this design, the first and second exhaust ports are divided into multiple grid-like air outlet channels by the flow divider ribs. This disperses the airflow into multiple streams as it passes through, thereby reducing the airflow velocity and thus reducing the noise generated by airflow turbulence. It also reduces the whistling sound generated when the airflow is flowing at high speed, improving the user experience.

[0026] The lid is provided with a drive mechanism; the drive mechanism is electrically connected to the control unit of the cooking appliance to control the pressure switching valve to switch between an on and off state; or, the lid is provided with an operating mechanism to drive the drive mechanism to switch the pressure switching valve between an on and off state.

[0027] In this solution, the pressure switching valve can be automatically switched between different states by electrically connecting the drive unit to the control unit and associating the pressure switching valve with the control program of the cooking appliance. This process eliminates the need for manual operation by the user, reducing the difficulty of operation. Alternatively, the drive unit can be manually controlled by setting an operating unit. The user can drive the operating unit to switch the state of the pressure switching valve, further improving the functional flexibility of the cooking appliance. Users can adjust and set the cooking mode according to their needs to meet different cooking requirements. Attached Figure Description

[0046] like Figure 1 , Figure 2 , Figure 3 As shown, a cooking appliance includes a pot body 1, a pot lid 2, and a venting box 3 disposed on the pot lid 2. The pot lid 2 is provided with a venting valve 23 and a pressure conversion valve 24. The pressure conversion valve 24 has an open state and a closed state. The venting box 3 has a first venting chamber 31 and a second venting chamber 32 that are separated from each other. The first venting chamber 31 is connected to the venting valve 23, and the second venting chamber 32 is connected to the pressure conversion valve 24. The venting box 3 has a first venting port 312 that is connected to the first venting chamber 31 and a second venting port 322 that is connected to the second venting chamber 32.

[0047] The pressure switching valve 24 has an open state and a closed state, thus enabling the cooking appliance to have both atmospheric pressure cooking mode and high pressure cooking mode. In atmospheric pressure cooking mode, the cooking chamber is connected to the outside atmosphere through the pressure switching valve 24, and the pot remains at atmospheric pressure throughout the cooking process. In high pressure cooking mode, the cooking chamber is isolated from the outside at the pressure switching valve 24, so that after the float is raised, the cooking chamber is completely isolated from the outside, and pressure can be applied inside the cooking chamber for high pressure cooking.

[0048] The exhaust box 3 is installed on the top surface of the pot lid 2, which can shield the exhaust valve 23 and the pressure conversion valve 24, realizing the hidden design of each exhaust structure and improving the simplicity and aesthetics of the pot lid 2. At the same time, various baffle structures can be set inside the exhaust box 3 to block the airflow, or reduce the kinetic energy of the airflow by lengthening the air path, thereby achieving the purpose of noise reduction during the exhaust process.

[0049] The exhaust box 3 has a first exhaust chamber 31 connected to the exhaust valve 23 and a second exhaust chamber 32 connected to the pressure switching valve 24. The first exhaust chamber 31 and the second exhaust chamber 32 are separated from each other. On the one hand, this prevents the airflow from the exhaust valve 23 and the pressure switching valve 24 from mixing, ensuring their respective exhaust efficiency and avoiding turbulence caused by collisions between the two airflows, which would generate noise and affect exhaust efficiency. On the other hand, the airflow and liquid ejected from the exhaust valve 23 can only flow in the first exhaust chamber 31 and cannot enter the second exhaust chamber 32, thus preventing them from reaching the pressure switching valve 24 and entering the pot lid 2 through it. This avoids hot airflow flowing back into the pot lid 2, causing the pot lid 2 to heat up and ensuring a better tactile experience for the user when operating the pot lid 2. It also prevents thick soup overflowing from the exhaust valve 23 from flowing to the pressure switching valve 24 and causing it to stick, ensuring the smooth flow of the pressure switching valve 24.

[0050] It is understandable that the exhaust valve 23 and the pressure switching valve 24 can exhaust simultaneously or independently. Regardless of whether they exhaust simultaneously or independently, the airflow they discharge is within their respective chambers and will not flow into another chamber.

[0051] like Figure 2 As shown, the exhaust valve 23 includes an exhaust pipe and a counterweight placed at the top of the exhaust pipe. The counterweight blocks the exhaust pipe. When exhausting, the exhaust assembly lifts the counterweight, causing it to separate from the exhaust pipe and break the seal.

[0052] Preferably, the noise-canceling box is detachably fixed to the top surface of the pot lid 2, allowing the user to remove the noise-canceling box for cleaning its interior. Specifically, such as... Figure 1 , Figure 8 As shown, the side wall of the exhaust box 3 is provided with a snap-fit ​​part 39, which is elastically connected to the exhaust box 3 so that the snap-fit ​​part 39 can elastically float relative to the exhaust box 3. The top wall of the pot lid 2 is provided with a mounting groove 21 for mounting the exhaust box 3, and the side wall of the mounting groove 21 is provided with a snap-fit ​​groove 22. The snap-fit ​​part 39 is used to snap and fix with the snap-fit ​​groove 22.

[0053] In one embodiment, such as Figure 4 , Figure 5 As shown, the first exhaust chamber 31 and the second exhaust chamber 32 are arranged horizontally side by side to simplify the internal structure of the exhaust box 3, facilitate manufacturing, and allow users to clean the interior. Of course, in other embodiments, one of the first exhaust chamber 31 and the second exhaust chamber 32 may surround the outer periphery of at least a portion of the other to reduce the overall volume of the exhaust box 3; this is not a limitation here.

[0054] Furthermore, such as Figure 4 , Figure 5 As shown, the volume of the first exhaust chamber 31 is larger than that of the second exhaust chamber 32. The main function of the exhaust valve 23 is to discharge the gas inside the pot after pressure cooking, thereby achieving pressure reduction. Due to the large pressure difference between the inside and outside of the pot during this exhaust process, the gas inside the pot will be ejected at high speed through the exhaust valve 23 under the action of the pressure difference, resulting in a large exhaust volume and high kinetic energy. Therefore, the larger volume of the first exhaust chamber 31 helps to buffer the airflow, reduce the kinetic energy of the airflow, and allow the gas to be discharged at a slower flow rate, thereby reducing the whistling sound and the sound of airflow collision. When the pressure conversion valve 24 is turned on, the cooking appliance cooks in atmospheric pressure mode. During the cooking process, the airflow inside the pot can be discharged in time through the pressure conversion valve 24. Therefore, the exhaust volume and kinetic energy of the pressure conversion valve 24 are smaller, and the smaller volume of the second exhaust chamber 32 can meet the requirements of smooth exhaust and noise reduction.

[0055] As a preferred embodiment of this utility model, such as Figure 4 As shown, the bottom wall of the first exhaust chamber 31 is provided with a first pair of interfaces 33 that connect with the exhaust valve 23, and a first water collection tank 311 surrounding the first pair of interfaces 33. The bottom wall of the second exhaust chamber 32 is provided with a second pair of interfaces 34 that connect with the pressure conversion valve 24, and a second water collection tank 321 surrounding the second pair of interfaces 34.

[0056] The first pair of interfaces 33 is used to connect with the exhaust valve 23, allowing the airflow discharged from the exhaust valve 23 to enter the first exhaust chamber 31 through the first pair of interfaces 33. The second pair of interfaces 34 is used to connect with the pressure switching valve 24, allowing the airflow discharged from the pressure switching valve 24 to enter the second exhaust chamber 32 through the second pair of interfaces 34. A first water collection tank 311 is provided on the outer periphery of the first pair of interfaces 33, and a second water collection tank 321 is provided on the outer periphery of the second pair of interfaces 34. During the exhaust process, some of the steam in the two exhaust chambers will come into contact with the inner walls of the two exhaust chambers to form condensate, which will then flow back or drip into the first water collection tank 311 and the second water collection tank 321, realizing the collection of condensate, which is convenient for users to clean centrally and prevents condensate from flowing back into the pot lid 2.

[0057] It should be noted that this embodiment does not limit the formation method of the first water collection tank 311 and the second water collection tank 321. In one embodiment, the bottom wall of the first exhaust chamber 31 can be recessed downward in the area on the outer periphery of the first pair of interfaces 33 to form the first water collection tank 311. Similarly, the bottom wall of the second exhaust chamber 32 can be recessed downward in the area on the outer periphery of the second pair of interfaces 34 to form the second water collection tank 321.

[0058] In a preferred embodiment, such as Figure 4 , Figure 5As shown, the outer periphery of the first pair of interfaces 33 and the second pair of interfaces 34 are provided with ribs 35 extending toward the interior of the exhaust box 3, so as to form a first water collection tank 311 and a second water collection tank 321 on the outer side of the ribs 35.

[0059] The retaining rib 35 extends inward toward the interior of the vent box 3 and surrounds the outer periphery of the first pair of interfaces 33 and the second pair of interfaces 34, such that the upper edge of the retaining rib 35 is higher than the outer area of ​​the first pair of interfaces 33 and the second pair of interfaces 34. This naturally forms a groove structure on the outer side of the retaining rib 35 for collecting liquids such as condensate. At the same time, the retaining rib 35 also blocks the liquid in the first water collection tank 311 and the second water collection tank 321, preventing it from flowing to the first pair of interfaces 33 and the second pair of interfaces 34, further reducing the risk of liquid backflow into the pot lid 2. Preferably, the retaining rib 35 also extends downward to protrude from the bottom wall of the vent box 3, thereby facilitating docking with the vent valve 23 and the pressure conversion valve 24 on the pot lid 2, improving the docking seal and reducing the possibility of air leakage.

[0060] In addition, by setting a height difference between the rib 35 protruding towards the inside of the exhaust box 3 and its outer area, forming the first water collection tank 311 and the second water collection tank 321, it is possible to avoid increasing the thickness of the exhaust box 3, which helps to achieve a flatter and thinner structure for the exhaust box 3.

[0061] Preferably, such as Figure 4 As shown, the first exhaust port 312 is disposed on the top wall of the first exhaust chamber 31 and is disposed vertically corresponding to the first water collection tank 311, and the second exhaust port 322 is disposed on the top wall of the second exhaust chamber 32 and is disposed vertically corresponding to the second water collection tank 321.

[0062] The first exhaust port 312 and the first interface 33 are vertically offset, and the second exhaust port 322 and the second interface 34 are also vertically offset. This elongates the airflow path within the first exhaust chamber 31 and the second exhaust chamber 32, helping to reduce the kinetic energy of the airflow and thus achieving noise reduction and gas-liquid separation. Simultaneously, the first exhaust port 312 corresponds vertically to the first water collection tank 311, and the second exhaust port 322 corresponds vertically to the second water collection tank 321. This ensures that when the steam flowing to the first exhaust port 312 and the second exhaust port 322 condenses into condensate upon cooling, it can drip directly into the first water collection tank 311 and the second water collection tank 321, guaranteeing the effective collection of condensate by the first water collection tank 311 and the second water collection tank 321.

[0063] As a preferred embodiment of this utility model, such as Figure 4 , Figure 5 , Figure 7As shown, the bottom wall of the first exhaust chamber 31 is provided with a first pair of interfaces 33 that connect with the exhaust valve 23, and the bottom wall of the second exhaust chamber 32 is provided with a second pair of interfaces 34 that connect with the pressure conversion valve 24. A baffle is provided between the first pair of interfaces 33 and the second pair of interfaces 34 to separate the first exhaust chamber 31 and the second exhaust chamber 32.

[0064] The baffle located between the first pair of interfaces 33 and the second pair of interfaces 34 separates the first exhaust chamber 31 and the second exhaust chamber 32, while ensuring that the first pair of interfaces 33 and the second pair of interfaces 34 are located in the two exhaust chambers respectively. The airflow discharged by the pressure switching valve 24 and the exhaust valve 23 flows and is discharged in their respective chambers without mixing. At the same time, the condensate formed by the vapor liquefaction, as well as the liquid and foam that rise with the airflow, are also collected in their respective chambers.

[0065] Specifically, this utility model does not limit the location of the retaining rib, which can be one of the following embodiments:

[0066] Example 1: In this example, the exhaust box 3 includes a base 36 and a cover 37. The baffle includes a first baffle 361 disposed on the base 36 and extending toward the cover 37. The first baffle 361 is disposed on the base 36, extends upward and abuts against the cover 37, thereby separating the first exhaust chamber 31 and the second exhaust chamber 32.

[0067] Example 2: In this example, the exhaust box 3 includes a base 36 and a cover 37. The baffle includes a second baffle 371 disposed on the base 36 and extending toward the cover 37. By providing the downwardly extending second baffle 371 on the cover 37, it abuts against the base 36 to separate the first exhaust chamber 31 and the second exhaust chamber 32.

[0068] Example 3: In this example, as Figure 4 , Figure 5 , Figure 7 As shown, the exhaust box 3 includes a base 36 and a cover 37. The baffle includes a first baffle 361 disposed on the base 36 and extending toward the cover 37, and a second baffle 371 disposed on the base 36 and extending toward the cover 37. The first baffle 361 and the second baffle 371 abut and seal to jointly separate the first exhaust chamber 31 and the second exhaust chamber 32.

[0069] Specifically, the upper end of the first baffle 361 can abut against the lower end of the second baffle 371 to seal the vertical gap between them. Alternatively, the side of the first baffle 361 can abut against the side of the second baffle 371 to seal the lateral gap between them; this is not limited here.

[0070] In the three embodiments described above, the base 36 and the cover 37 can be an integrally formed and non-separable structure, or the cover 37 and the base 36 can be detachably connected so that the exhaust box 3 can be opened for easy cleaning by the user.

[0071] Preferably, the vent box 3 includes a base 36 and a cover 37. The base 36 is detachably mounted on the pot lid 2, and the cover 37 is movable relative to the base 36 to open or close the base 36.

[0072] The cover 37 can move relative to the base 36 to open the exhaust box 3, fully exposing its internal structure. Users can then clean the internal interfaces and the liquid collected inside the exhaust box 3. This facilitates cleaning the exhaust box 3 and improves the user experience.

[0073] In one embodiment, the cover 37 can be removed from the base 36, thereby fully opening the base 36 for user cleaning. Specifically, a sealing ring can be provided between the base 36 and the cover 37, and the base 36 and the cover 37 are fixed together by an interference fit. In another embodiment, as... Figure 7 As shown, the cover 37 has a connecting end and a locking end that are arranged opposite to each other. The connecting end is rotatably connected to the base 36, and the locking end can be locked or unlocked with the base 36 so that the cover 37 can be flipped around the connecting end.

[0074] By rotating one end of the cover 37 to the base 36, the cover 37 can be flipped up and down around the connecting end to close or open the base 36, thus fully opening the base 36. This facilitates thorough cleaning of the interior of the exhaust box 3 by the user, and the opening and closing operations are relatively simple and user-friendly. Furthermore, since one end of the cover 37 remains connected to the base 36 at all times, when the cover is open, the user is spared the hassle of storing the cover 37, effectively preventing its loss.

[0075] Preferably, the connecting end and the base 36 are connected by a pivot, such as... Figure 5 , Figure 7 As shown, the locking end is provided with a first latching part 362, and the base 36 is provided with a corresponding second latching part 372, so that the two are latched and locked together.

[0076] Of course, the cover 37 can also move relative to the base 36 in other ways to open or close the base 36, such as the cover 37 can rotate horizontally relative to the base 36, or slide horizontally, etc., which is not limited here.

[0077] In a preferred embodiment, such as Figure 3 , Figure 6As shown, a flow divider 38 is provided at the first exhaust port 312 and the second exhaust port 322, and the flow divider 38 divides the first exhaust port 312 and the second exhaust port 322 into multiple exhaust channels 381.

[0078] The first exhaust port 312 and the second exhaust port 322 are divided into multiple grid-like air outlet channels 381 by the flow divider 38, so that when the airflow passes through, it is dispersed into multiple streams by the flow divider 38, thereby reducing the airflow velocity, thereby reducing the noise generated by airflow turbulence, and also reducing the whistling sound generated when the airflow flows at high speed, thus improving the user experience.

[0079] Specifically, the flow dividers 38 can be arranged at intervals along a straight line so that the air outlet channels 381 are arranged in a row, or the flow dividers 38 can be arranged in a crisscross pattern so that the air outlet channels 381 are arranged in a grid pattern, or the air outlet channels 381 can be arranged in a honeycomb pattern, etc., without limitation.

[0080] Preferably, the cross-sectional area of ​​the first exhaust chamber 31 is larger than the area of ​​the first interface 33, and the cross-sectional area of ​​the second exhaust chamber 32 is larger than the area of ​​the second interface 34, in order to reduce airflow velocity and noise. The area of ​​a single exhaust channel 381 at the first exhaust port 312 is less than or equal to the area of ​​the first interface 33, and the sum of the areas of all exhaust channels 381 is greater than or equal to the area of ​​the exhaust port of the exhaust valve 23. Similarly, the area of ​​a single exhaust channel 381 at the second exhaust port 322 is less than or equal to the area of ​​the second interface 34, and the sum of the areas of all exhaust channels 381 is greater than or equal to the area of ​​the exhaust port of the pressure switching valve 24.

[0081] It should be noted that this utility model does not limit the control method of the pressure switching valve 24. In one embodiment, the pot lid 2 is provided with a driving component; the driving component is electrically connected to the control unit of the cooking appliance to control the switching of the pressure switching valve 24 between the open and closed states. By electrically connecting the driving component to the control unit, the pressure switching valve 24 is associated with the control program of the cooking appliance, thereby realizing the automatic switching of different states of the pressure switching valve 24. This process does not require manual operation by the user, reducing the difficulty of user operation.

[0082] In another embodiment, the pot lid 2 is equipped with a drive component and an operating component. The operating component drives the drive component to switch the pressure switching valve 24 between an on and off state. By providing the operating component, manual control of the drive component is achieved. The user can drive the operating component to switch the state of the pressure switching valve 24. This manual operation further enhances the functional flexibility of the cooking appliance, allowing the user to adjust and set the cooking mode as needed to meet different cooking requirements.

[0083] Specifically, this invention does not limit the switching state of the pressure switching valve 24. For example, in one specific example, it includes a valve body and a valve core, and the valve body can be opened or closed by controlling the movement of the valve core. In another specific example, the switching between the two states can be achieved by controlling the overall movement of the pressure switching valve 24. For example, when the pressure switching valve 24 moves upward to its designated position, its vent is blocked, and it is in a closed state. When it moves downward to its designated position, its vent is open, and it is in a conducting state. Of course, the pressure switching valve 24 can also achieve the switching between the conducting and closed states in other ways, which are not limited here.
