Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a water-cooled pot cover assembly and a pressure cooking appliance. Background Art

[0002] After pressure cooking, pressure cookers need to release the pressure to equalize the pressure inside the pot with the outside atmosphere before the lid can be opened safely. Traditional pressure cookers release pressure through venting, which is not only slow but also noisy. The venting process can also cause liquid in the pot to spray out, contaminating the lid and affecting the user experience.

[0003] Some pressure cooking appliances also use water cooling for pressure relief. Compared to exhaust, water cooling is faster and produces less noise during the process, making it increasingly popular. Cooking appliances using water cooling typically have a water-cooling chamber in the lid, which cools the pot by passing cooling liquid through the chamber to relieve pressure.

[0004] To ensure effective water cooling, the walls of the water-cooling chamber are typically located inside the pot. However, during the cooling process, coolant enters the chamber, causing the walls to cool. When the hot steam inside the pot comes into contact with the coolant, it quickly liquefies and forms condensate, which adheres to the walls. This condensate eventually drips into the pot and mixes with the food.

[0005] Therefore, the location of the water-cooling chamber is the location where the condensed water drips. In the prior art, the water-cooling chamber is usually eccentric to the pot lid, so that the condensed water on the water-cooling chamber wall drips on one side of the cooking chamber and cannot be well mixed with the soup. As a result, the soup on that side is thinner due to the addition of condensed water, while the soup on the other side is thicker due to less condensed water, resulting in a large difference in the taste of the food on both sides, seriously affecting the overall taste of the food.

[0006] Furthermore, the water-cooling chamber is typically located on or within the inner cover, or formed by other components in conjunction with the inner cover. However, some cooking appliances feature a removable or rotatable inner cover. This can cause the water-cooling chamber to be removed or rotated along with the inner cover. Frequent connection and disconnection, as well as the movement of the water-cooling chamber and water-cooling piping, can compromise the sealability of the connection, posing a risk of coolant leakage. Utility Model Content

[0007] The utility model provides a water-cooled pot cover assembly and a pressure cooking appliance to solve the problems that condensed water dripping from the cooling cavity wall cannot be well mixed with the food in the pot, resulting in a large difference in the taste of the food on both sides, and the connection between the water-cooling pipeline and the water-cooling cavity is unstable and the sealing is poor.

[0008] The technical solution adopted by this utility model is:

[0009] A water-cooled pot cover assembly includes a cover body and an inner cover located on the lower side of the cover body, the inner cover is used to cooperate with the pot body to form a cooking cavity, the cover body is provided with a downwardly protruding cooling member, the cooling member has a cooling cavity connected to the water cooling assembly inside, the cooling member is located at the center of the inner cover, the center of the inner cover is provided with a through hole, the cooling member passes through the through hole to extend to the bottom of the inner cover; the cooling cavity has a water inlet end and a water outlet end arranged oppositely, and the cooling liquid in the cooling cavity flows from the water inlet end to the water outlet end.

[0010] The water-cooled pot cover assembly of the utility model also has the following additional technical features:

[0011] The lower end of the cooling element is provided with a guide tip to guide the liquid on the surface of the cooling element to drip.

[0012] A shielding rib is provided on the lower side of the inner cover. The shielding rib surrounds the outer periphery of the cooling element, and a gap is provided between the outer periphery of the cooling element and the shielding rib.

[0013] The lower edge of the cooling element is lower than the lower edge of the shielding rib.

[0014] The inner cover is detachably fixed to the cover body. The cover body is also provided with a temperature measuring component and an exhaust pipe. The inner cover has a matching area corresponding to the temperature measuring component and a matching opening for the exhaust pipe to pass through. The matching area and the matching opening are respectively located on both sides of the through hole.

[0015] The matching area is provided with an opening for the temperature measuring piece to pass through, and the opening, the through hole and the matching opening are all located on the center line of the inner cover.

[0016] The water-cooled pot cover assembly also includes a locking ring, which can rotate relative to the cover body to lock or unlock the water-cooled pot cover assembly and the pot body. The locking ring forms an escape opening, and the cooling element passes through the escape opening.

[0017] The cover body includes a surface cover and a lining cover located below the surface cover, an installation space is provided between the lining cover and the surface cover, and the water-cooled pot cover assembly also includes a water pump provided in the installation space, and the vertical projection of the water pump is located outside the inner cover.

[0018] The utility model also discloses a pressure cooking appliance, comprising a pot body and the above-mentioned water-cooled pot cover assembly, the water-cooled pot cover assembly having a connecting end and an opening and closing end that are relatively arranged, the connecting end being rotatably connected to the pot body, and the opening and closing end being able to flip around the connection to open or close the pot body, the pot body or the water-cooled pot cover assembly being provided with a water tank, and the water tank being connected to the cooling chamber.

[0019] The water tank is arranged on the water-cooled pot cover assembly, and the distance between the water tank and the connecting end is smaller than the distance between the water tank and the opening and closing end.

[0020] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0021] 1. In the present invention, the inner lid and the pot body cooperate to form a cooking cavity, so the center of the inner lid corresponds to the center of the cooking cavity. During cooking, heat is concentrated in the center of the cooking cavity. Therefore, the placement of the cooling element in this area creates a significant temperature difference between the cooling element and the cooking cavity, significantly improving heat exchange efficiency and achieving rapid cooling. Furthermore, when the high-temperature steam in the cooking cavity comes into contact with the cooler cooling element, the steam quickly liquefies into condensed water, which then adheres to the surface of the cooling element. As the condensed water accumulates on the surface of the cooling element, it drips from the cooling element into the cooking cavity. The cooling element is located in the center of the cooking cavity, where the food is hotter, causing the soup to swirl more vigorously. Therefore, any condensed water dripping from the cooling element quickly dissolves into the soup. This ensures more even mixing of the soup and condensed water, preventing the soup from being thinner on one side and thicker on the other, which could result in different tastes. It also facilitates the reuse of condensed water, minimizing soup loss.

[0022] In addition, since the cooling element is arranged on the cover body, even if the inner cover can rotate relative to the cover body, the cover body will not move, thereby ensuring that the cooling element and the water-cooling pipeline connected to the cooling element will not change position, thereby maintaining a stable connection and seal between the water-cooling pipeline and the cooling chamber, thereby improving the reliability of the pipeline connection. When the inner cover is removed from the cover body, the cooling element always remains on the cover body and does not change position with the installation and removal of the inner cover. Therefore, on the one hand, the user does not need to dock the water-cooling pipeline with the cooling chamber when installing the inner cover, which reduces the installation and removal efficiency of the inner cover and the convenience of operation, and improves the user experience. On the other hand, the water-cooling pipeline can always remain connected to the cooling chamber, and there is no need to frequently connect the water-cooling pipeline and the cooling chamber, thereby ensuring the sealing of the connection, further reducing the risk of water-cooling liquid leakage, and ensuring water cooling efficiency.

[0023] Not only that, the water inlet and outlet are relatively arranged on both sides of the cooling chamber, so that after the coolant enters the cooling chamber, it can flow through the area inside the cooling chamber more completely, making the flow path of the coolant in the cooling chamber longer, thereby extending the contact time between the coolant and the air in the pot and improving the heat exchange effect.

[0024] 2. As a preferred embodiment of the present invention, a guide tip is provided at the lower end of the cooling element to guide liquid dripping from the cooling element surface. The guide tip guides condensed water and other liquids on the cooling element surface to flow downward and eventually drip, preventing condensed water and food juices from accumulating on the cooling element for a long time and affecting the heat exchange efficiency between the cooling element and the gas in the cooking chamber, while also ensuring the cleanliness of the cooling element.

[0025] 3. As a preferred embodiment of the present invention, shielding ribs are provided on the lower side of the inner cover. The shielding ribs surround the outer periphery of the cooling element, and a gap is provided between the outer periphery of the cooling element and the shielding ribs. The shielding ribs surround the outer periphery of the cooling element, which can play a certain barrier role for liquid and solid food in the cooking cavity, reduce the probability of liquid and solid food coming into contact with the cooling element, and prevent food from adhering to the surface of the cooling element, resulting in a decrease in the cooling efficiency of the cooling element. The gap between the shielding ribs and the cooling element allows gas in the cooking cavity to enter, thereby surrounding the outer periphery of the cooling element and making full contact with the cooling element, thereby increasing the contact area between the high-temperature gas and the cooling element and improving the heat exchange efficiency.

[0026] 4. As a preferred embodiment of the present invention, the inner cover is detachably fixed to the cover body. The cover body is also provided with a temperature measuring element and an exhaust pipe. The inner cover has a matching area corresponding to the temperature measuring element and a matching opening for the exhaust pipe to pass through. The matching area and the matching opening are respectively located on either side of the through hole. Since the inner cover can be removed from the cover body, each time the user removes the inner cover and cleans it, the user needs to reinstall the inner cover on the cover body before cooking. The inner cover is usually circular, so when installing the inner cover, positioning the inner cover is a major problem that bothers users. In this embodiment, the through hole of the inner cover cooperates with the cooling element of the cover body, the matching area cooperates with the temperature measuring element of the cover body, and the matching opening cooperates with the exhaust pipe. The matching opening and the matching area are respectively located on either side of the through hole, so that the three sets of matching structures constitute the three-point positioning of the inner cover installation. The user can use the three sets of matching structures as a reference to position the inner cover and then install the inner cover to the cover body, thereby reducing the difficulty of positioning the inner cover and improving the efficiency of inner cover installation.

[0027] 5. As a preferred embodiment of the present invention, a water tank is provided in the water-cooled pot lid assembly, and the distance between the water tank and the connection end is smaller than the distance between the water tank and the opening and closing end. The water tank is closer to the rotation center of the pot lid assembly, and the lever arm between the water tank and the rotation center of the pot lid assembly is shorter. On the one hand, this causes the structural center of gravity of the pot lid assembly to move backward, closer to the rotation center. Therefore, the torsion force required of components such as torsion springs that dampen or assist the movement of the pot lid is small. At the same time, the torsion springs are subjected to less stress, and are less likely to break or be damaged, thereby increasing their service life and saving costs. Moreover, the force exerted by the torsion springs on the pot lid assembly is more stable, and the pot lid assembly moves more smoothly during flipping and opening, reducing the shaking of the pot lid assembly. At the same time, since the center of gravity of the pot lid assembly is closer to the connection end, the user can save more effort when operating the opening and closing of the lid.

[0041] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0043] In addition, in the description of the present invention, it should be understood that the terms "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components.

[0045] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "implementation method", "embodiment", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0046] like Figure 1 、 Figure 2 、 Figure 6 As shown, a water-cooled pot cover assembly includes a cover body 1 and an inner cover 2 located on the lower side of the cover body 1, the inner cover 2 is used to cooperate with the pot body to form a cooking cavity, the cover body 1 is provided with a downwardly protruding cooling member 13, the cooling member 13 has a cooling cavity 131 connected to the water cooling assembly inside, the cooling member 13 is located at the center of the inner cover 2, the center of the inner cover 2 is provided with a through hole 21, the cooling member 13 passes through the through hole 21 to extend to the bottom of the inner cover 2; the cooling cavity 131 has a water inlet end 1311 and a water outlet end 1312 arranged oppositely, and the coolant in the cooling cavity 131 flows from the water inlet end 1311 to the water outlet end 1312.

[0047] It should be noted that although the present invention is provided with a cooling chamber 131 in the pot cover assembly and can use water cooling to reduce temperature for pressure relief, the present invention is not limited to using only water cooling for pressure relief. For example, the pot cover assembly can also be provided with an exhaust assembly to assist in pressure relief. During the pressure relief stage after cooking, pressure relief can be achieved through the combination of water cooling and exhaust. By using water cooling to reduce pressure, it is not necessary to exhaust the air by opening the exhaust valve during pressure relief. While ensuring the pressure relief speed, the whistling sound of the airflow emitted during exhaust is reduced, thereby reducing noise, and preventing liquid from spraying out and contaminating the pot cover, thereby greatly improving the user experience.

[0048] In the present invention, the inner lid 2 and the pot body cooperate to form a cooking cavity, so the center of the inner lid 2 corresponds to the center of the cooking cavity. During cooking, heat is concentrated in the center of the cooking cavity. Therefore, the cooling element 13 is positioned there, creating a significant temperature difference between the cooling element 13 and the interior of the cooking cavity, significantly improving heat exchange efficiency and achieving rapid cooling. Furthermore, when the high-temperature steam in the cooking cavity comes into contact with the cooler cooling element 13, the steam quickly liquefies into condensed water, which then adheres to the surface of the cooling element 13. As the condensed water accumulates on the surface of the cooling element 13, it drips from the surface into the cooking cavity. Because the cooling element 13 is located at the center of the cooking cavity, the food in the center is hotter, causing the soup to swirl more vigorously. Therefore, any condensed water dripping from the cooling element 13 quickly dissolves into the soup. This ensures more even mixing of the soup and condensed water, preventing a thinner soup on one side and a thicker soup on the other, which could result in different tastes. It also facilitates the reuse of the condensed water, minimizing soup loss.

[0049] In addition, since the cooling element 13 is provided on the cover body 1, even if the inner cover 2 can rotate relative to the cover body 1, the cover body 1 will not move, thereby ensuring that the cooling element 13 and the water-cooling pipeline connected to the cooling element 13 will not change position, thereby maintaining a stable connection and seal between the water-cooling pipeline and the cooling cavity 131, thereby improving the reliability of the pipeline connection. When the inner cover 2 is removed from the cover body 1, the cooling element 13 always remains on the cover body 1 and does not change position with the installation and removal of the inner cover 2. Therefore, on the one hand, the user does not need to dock the water-cooling pipeline with the cooling cavity 131 when installing the inner cover 2, which reduces the installation and removal efficiency of the inner cover 2 and the convenience of operation, and improves the user experience. On the other hand, the water-cooling pipeline can always remain connected to the cooling cavity 131, and there is no need to frequently connect the water-cooling pipeline and the cooling cavity 131, thereby ensuring the sealing of the connection, further reducing the risk of water-cooling liquid leakage, and ensuring water cooling efficiency.

[0050] In summary, after the water-cooling assembly of the present invention is connected to the cooling chamber 131 through a pipeline, in subsequent use, no matter the user rotates the inner cover 2 or removes the inner cover 2, the cooling chamber 131 will never be separated from the pot cover, and the relative position with the water tank 4 will always remain fixed, and there is no relative movement between the two. Therefore, the position of the pipeline also remains stable, and a reliable connection is always maintained.

[0051] Not only that, if Figure 6 As shown, the water inlet end 1311 and the water outlet end 1312 are relatively arranged on both sides of the cooling cavity 131, so that after the coolant enters the cooling cavity 131, it can flow through the area inside the cooling cavity 131 more completely, making the flow path of the coolant in the cooling cavity 131 longer, thereby extending the contact time between the coolant and the air in the pot and improving the heat exchange effect.

[0052] Preferably, if Figure 6 As shown, the water inlet end 1311 and the water outlet end 1312 are both located on the upper side of the cooling member 13 to facilitate connection with the pipeline of the cover body 1 and shorten the pipeline length, and the water inlet end 1311 and the water outlet end 1312 are relatively arranged on both sides of the cooling member 13 along the width direction or radial direction of the cooling member 13.

[0053] Preferably, if Figure 2 As shown, the outer diameter D of the cooling member 13 satisfies: 10 mm ≤ D ≤ 40 mm.

[0054] Because cooling element 13 is mounted on lid 1 and extends through inner lid 2 into the cooking cavity, during pressure cooking, cooling element 13 is directly affected by the pressure inside the pot, exerting a vertical upward force on lid 1. This force is ultimately transmitted to lid 1. The force exerted by cooling element 13 on lid 1 is proportional to the square of its outer diameter. If the outer diameter of cooling element 13 is too large, the force exerted on lid 1 is excessive, potentially causing deformation or rupture of lid 1. However, if the outer diameter of cooling element 13 is too small, the volume of cooling cavity 131 within it is reduced, reducing the contact area between cooling element 13 and the gas inside the cooking cavity and reducing the cooling effect. By setting the outer diameter of cooling element 13 between 10 mm and 40 mm, while ensuring the contact area between cooling element 13 and the high-temperature gas inside the pot, the force exerted by cooling element 13 on lid 1 during pressure cooking is reduced to a certain extent, ensuring the structural stability of lid 1 and improving its service life.

[0055] As a preferred embodiment of the present invention, Figure 2 As shown, a guide tip 132 is provided at the lower end of the cooling member 13 to guide the liquid on the surface of the cooling member 13 to drip.

[0056] The guide tip 132 can guide the condensed water and other liquids on the surface of the cooling element 13 to flow downward and eventually drip, thereby preventing the condensed water and food soup from accumulating on the cooling element 13 for a long time, affecting the heat exchange efficiency between the cooling element 13 and the gas in the cooking cavity, and ensuring the cleanliness of the cooling element 13.

[0057] Preferably, if Figure 2 As shown, the lower end of the cooling member 13 is provided with an arc surface, and the lower end of the arc surface forms a guide tip 132. Of course, the lower end of the cooling member 13 can also be other shapes, such as an inclined surface structure, etc., which is not limited here.

[0058] In a preferred embodiment, Figure 2 As shown, a shielding rib 24 is provided on the lower side of the inner cover 2 , and the shielding rib 24 surrounds the outer periphery of the cooling element 13 , and a gap is formed between the outer periphery of the cooling element 13 and the shielding rib 24 .

[0059] Shielding ribs 24 surround the outer periphery of cooling element 13, providing a barrier to liquid and solid food within the cooking chamber. This reduces the likelihood of liquid and solid food coming into contact with cooling element 13, preventing food from adhering to the surface and reducing cooling efficiency. The gap between shielding ribs 24 and cooling element 13 allows gas from the cooking chamber to enter, surrounding and fully contacting cooling element 13. This increases the contact area between the high-temperature gas and cooling element 13, improving heat exchange efficiency.

[0060] Furthermore, if Figure 2 As shown, the lower edge of the cooling member 13 is lower than the lower edge of the shielding rib 24 to prevent the shielding rib 24 from blocking a large amount of gas in the cooking cavity and preventing it from contacting the cooling member 13, ensuring that the cooling member 13 can contact more gas to cool it down.

[0061] As a preferred embodiment of the present invention, Figure 1 、 Figure 4 、 Figure 5 As shown, the inner cover 2 is detachably fixed to the cover body 1. The cover body 1 is also provided with a temperature measuring component 14 and an exhaust pipe 15. The inner cover 2 has a matching area corresponding to the temperature measuring component 14 and a matching opening 22 for the exhaust pipe 15 to pass through. The matching area and the matching opening 22 are respectively located on both sides of the through hole 21.

[0062] Since the inner cover 2 can be removed from the cover body 1, each time the user removes the inner cover 2 and cleans it, the user needs to reinstall the inner cover 2 on the cover body 1 before cooking. The inner cover 2 is usually circular, so when installing the inner cover 2, the positioning of the inner cover 2 is a major problem that bothers the user. In this embodiment, the through hole 21 of the inner cover 2 cooperates with the cooling part 13 of the cover body 1, the matching area cooperates with the temperature measuring part 14 of the cover body 1, and the matching port 22 cooperates with the exhaust pipe 15. The matching port 22 and the matching area are respectively located on both sides of the through hole 21, so that the three groups of matching structures constitute the three-point positioning of the installation of the inner cover 2. The user can use the three groups of matching structures as a reference to position the inner cover 2, and then install the inner cover 2 to the cover body 1, thereby reducing the difficulty of positioning the inner cover 2 and improving the installation efficiency of the inner cover 2.

[0063] In one embodiment, the line connecting the through hole 21, the matching area and the matching opening 22 is a triangle. In order to improve the positioning accuracy. In another embodiment, as Figure 4 As shown, the mating area, through hole 21 and mating opening 22 are all located on the center line of the inner cover 2. The mating area, through hole 21 and mating opening 22 are collinear and located on the center line of the inner cover 2, which can optimize the structural layout of the inner cover 2 and facilitate installation and use.

[0064] It should be noted that this embodiment does not limit the coordination mode between the coordination zone and the temperature measuring element 14. In one embodiment, the coordination zone is a closed structure, and the temperature measuring element 14 contacts the coordination zone to indirectly detect the temperature in the cooking cavity by detecting the temperature of the coordination zone. In another embodiment, Figure 2 、 Figure 4 As shown, the mating area is provided with an opening 23, and the temperature measuring element 14 extends into the cooking cavity through the opening 23 to directly detect the temperature inside the cooking cavity. Preferably, a sealing structure is provided at the opening 23, the through hole 21 and the mating opening 22.

[0065] Of course, the inner cover 2 may also be configured to be non-detachably fixed to the cover body 1 , which is not limited here.

[0066] In addition, the locking and unlocking method of the pot lid assembly and the pot body can be one of the following embodiments:

[0067] Implementation method 1: In this implementation method, Figure 1 、 Figure 2 、 Figure 3 As shown, the pot cover assembly further includes a locking ring 3, which can rotate relative to the cover body 1 to lock or unlock the pot cover assembly and the pot body. The locking ring 3 forms an escape opening, and the cooling element 13 passes through the escape opening.

[0068] Specifically, such as Figure 2 、 Figure 3As shown, the locking ring 3 is provided with a cover tooth 31, and the pot body is provided with a pot tooth. The locking ring 3 can rotate relative to the lid body 1 to lock or unlock the pot tooth and the cover tooth 31, thereby locking or unlocking the pot lid assembly and the pot body. The locking ring 3 forms an escape hole, and the cooling element 13 passes through the escape hole, so that the inner lid 2 and the lid body 1 do not rotate with the locking ring 3, and the relative position of the cooling element 13 and the inner lid 2 remains unchanged.

[0069] Embodiment 2: In this embodiment, the inner lid 2 is provided with a cover tooth 31, and the pot body is provided with a pot tooth. The inner lid 2 can rotate relative to the lid body 1 to lock or unlock the pot tooth and the cover tooth 31, thereby locking or unlocking the pot lid and the pot body. Preferably, the cooling element 13 is located at the center of the inner lid 2 to ensure that the relative position of the inner lid 2 and the pot body does not change during rotation, thereby improving the sealing between the two.

[0070] Preferably, if Figure 2 As shown, the cover body 1 includes a surface cover 11 and a lining cover 12 located below the surface cover 11, an installation space 111 is provided between the lining cover 12 and the surface cover 11, and the water-cooled pot cover assembly also includes a water pump 5 provided in the installation space 111, and the vertical projection of the water pump 5 is located outside the inner cover 2.

[0071] The inner lid 2 and the pot body cooperate to form the cooking cavity, so the water pump 5 is located outside the inner lid 2, that is, outside the projection of the cooking cavity. During cooking, heat from the cooking cavity radiates onto the pot lid, where it is concentrated in the area covered by the projection of the cooking cavity. Placing the water pump 5 outside this area prevents direct heat transfer from the cooking cavity to the water pump 5, keeping it away from the heat-concentrated area on the pot lid. This effectively reduces the temperature of the water pump 5, allowing it to operate at a safe temperature, slowing the aging of its components due to high temperatures, and ultimately increasing its service life and reliability.

[0072] The present utility model also discloses a pressure cooking appliance, comprising a pot body and the above-mentioned water-cooled pot cover assembly, the water-cooled pot cover assembly having a connecting end 16 and an opening and closing end 17 arranged opposite to each other, the connecting end 16 being rotatably connected to the pot body, and the opening and closing end 17 being capable of flipping around the connection to open or close the pot body, the pot body or the water-cooled pot cover assembly being provided with a water tank 4, and the water tank 4 being connected to the cooling chamber 131.

[0073] On the center line of the pot cover in the front-to-back direction, the connecting end 16 is located at one end of the pot cover, and the opening and closing end 17 is located at the other end of the pot cover. The connecting end 16 is provided with a connecting arm for rotationally connecting with the pot body.

[0074] Furthermore, if Figure 1 、 Figure 2 、 Figure 3As shown, the water tank 4 is disposed within the water-cooled pot lid assembly, and the distance between the water tank 4 and the connection end 16 is smaller than the distance between the water tank 4 and the opening and closing end 17. Specifically, the horizontal straight-line distance between the water tank 4 and the connection end 16 is smaller than the horizontal straight-line distance between the water tank 4 and the opening and closing end 17. In other words, the pot lid can be divided into a front region and a rear region using the left and right centerlines as the dividing line, with the opening and closing end 17 located in the front region, the connection end 16 located in the rear region, and the water tank 4 located in the rear region, placing the water tank 4 closer to the connection end 16 than to the center of the pot lid assembly.

[0075] It should be noted that the center of the pot cover assembly coincides with the center of the inner cover 2, that is, the center of the pot cover assembly is also the center of the inner cover 2, and the center line is a straight line passing through the center. Figure 5 As shown, the lid body 1 includes a covering portion 18 and a hinge portion 19 located on the outer periphery of the covering portion 18 and protruding laterally, which is used to be rotatably connected to the pot body. The covering portion 18 corresponds to the inner lid 2, and the inner lid 2 is installed on the covering portion 18 and is concentric with the covering portion 18. The center of the lid body 1 refers to the center of the covering portion 18.

[0076] Water tank 4 is closer to the rotation center of the pot lid assembly, and the lever arm between water tank 4 and the rotation center of the pot lid assembly is shorter. This, on the one hand, shifts the structural center of gravity of the pot lid assembly backward, closer to the rotation center. Consequently, the torsion spring and other components that dampen or assist the pot lid's movement are less subject to torque. Furthermore, the torsion spring is subjected to less stress, making it less susceptible to breakage or damage, thereby increasing its service life and saving costs. Furthermore, the force exerted by the torsion spring on the pot lid assembly is more stable, making the pot lid assembly move more smoothly during flipping and opening, and reducing any shaking of the pot lid assembly. Furthermore, because the pot lid assembly's center of gravity is closer to the connection end 16, users can operate the lid with less effort.

[0077] Preferably, the water tank 4 is exposed on the surface of the pot lid assembly, allowing the user to observe the water level inside the water tank 4. It should be noted that the water tank 4 can either protrude from the surface of the lid 1 or be flush with the outer surface of the lid 1, forming part of the exterior appearance of the pot lid assembly. For example, a receiving groove can be provided on the top surface of the lid 1, and the water tank 4 can be placed within the receiving groove so that the top surface of the water tank 4 is substantially flush with the top surface of the lid 1. Furthermore, the water tank 4 is positioned at the edge of the lid 1, with the side surfaces of the water tank 4 substantially flush with the side surfaces of the lid 1. This provides a more uniform appearance for the cooking utensil and makes it easier for the user to remove or place the water tank 4 from one side.

[0078] In another embodiment, the water tank 4 is mounted within the pot body to make the lid assembly thinner and lighter, improving the user experience when opening and closing the lid. For example, the water tank 4 can be positioned on the front side of the pot body (corresponding to the side of the lid assembly's opening and closing end 17) to more efficiently utilize the pot body's internal space and shift the pot body's center of gravity forward, preventing it from tipping backward. Because the lid assembly and pot body are pivotally connected, a pipeline can be connected to the water pump 5 and the water tank 4 via the connection end 16.

[0079] Preferably, if Figure 2 As shown, the water pump 5 is also arranged close to the connection end 16 .
