Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a pot cover assembly and a cooking utensil. Background Art

[0002] The cooking utensil usually includes a pot body and a pot cover. The pot cover includes a cover and a metal inner cover. The metal inner cover cooperates with the pot body to form a cooking cavity. During the cooking process, the metal inner cover is in direct contact with the cooking environment in the pot. An exhaust channel is provided between the metal inner cover and the cover. The metal inner cover has an exhaust port. The steam in the pot directly enters the exhaust channel after passing through the exhaust port and is discharged from the exhaust valve.

[0003] During cooking, the lower side of the metal inner cover is directly heated by the steam rising from the pot, so the temperature is higher, while the upper side of the metal inner cover is lower, resulting in a large temperature difference between the two sides of the metal inner cover, which easily generates condensation water on the metal inner cover. When the user opens the pot lid, the condensation water on the metal inner cover slides down and drips into the pot, causing the food to become wet and affecting the taste, or drips onto the surface of the pot, contaminating the pot, increasing the cleaning burden of the user and providing a poor user experience.

[0004] In the prior art, there is a solution of setting two inner and outer sealing rings between the surface cover and the metal inner cover, so that the steam first flows between the inner and outer sealing rings and then is discharged from the exhaust valve. However, the main purpose of this solution is to break bubbles, and it cannot effectively reduce condensed water. Specifically, since the air passage between the inner and outer sealing rings is relatively narrow, the contact area between the steam in the passage and the metal inner cover is small, and the effect of steam on the heat preservation of the metal inner cover is limited. The metal inner cover will still produce more condensed water due to the temperature difference, which needs to be improved. Utility Model Content

[0005] The utility model provides a pot cover assembly and a cooking utensil to solve the problem that the temperature difference between the two sides of the metal inner cover is large and condensed water is easily generated.

[0006] The technical solution adopted by the utility model is:

[0007] A pot cover assembly comprises a lining cover and an inner cover detachably fixed to the lining cover, the inner cover comprises a metal cover plate, a pot mouth sealing ring and a fixing bracket, the fixing bracket is installed on the outer periphery of the metal cover plate, the pot mouth sealing ring is clamped and fixed between the fixing bracket and the metal cover plate, the lining cover is provided with a first sealing member, the free end of the first sealing member is located on the inner side of the fixing bracket and abuts against the metal cover plate to form a heat preservation cavity between the metal cover plate and the lining cover, the inner cover is provided with an air inlet connected to the heat preservation cavity, and the lining cover is provided with an air outlet connected to the heat preservation cavity, wherein the ratio of the cross-sectional area of ​​the heat preservation cavity to the cross-sectional area of ​​the metal cover plate is 0.5 to 0.9.

[0008] The pot cover assembly of the utility model also has the following additional technical features:

[0009] The lining cover is also provided with a temperature measuring component, the metal cover plate is provided with an opening corresponding to the temperature measuring component, a second sealing component is embedded in the opening, the second sealing component has a through hole, and the temperature measuring component passes through the through hole.

[0010] The lining cover is also provided with a temperature measuring component, the metal cover plate is provided with an opening corresponding to the temperature measuring component, the lining cover is also provided with a second sealing component surrounding the temperature measuring component, and the free end of the second sealing component abuts against the metal cover plate.

[0011] A positioning groove is arranged on one side of the metal cover plate facing the lining cover. The first sealing member has a sealing lip edge, which extends into the positioning groove and abuts against the groove wall of the positioning groove.

[0012] A barrier is arranged between the air inlet and the air outlet, and a first flow gap is formed between at least one end of the barrier and the first sealing member.

[0013] The air inlet and the air outlet are arranged oppositely on two sides of the blocking member.

[0014] A matching notch is arranged at one end of the barrier member close to the lining cover, and the matching notch cooperates with the lining cover to form a second flow gap; or a flow port is opened at one end of the barrier member close to the lining cover.

[0015] The lining cover is also provided with a temperature measuring component, and the inner cover is provided with an opening corresponding to the temperature measuring component, the opening constitutes an air inlet, and a baffle rib is provided between the opening and the air outlet.

[0016] The metal cover plate is also provided with a reflux port connected to the heat preservation cavity.

[0017] The utility model also discloses a cooking utensil, comprising a pot body and the pot cover assembly. When the pot cover assembly covers the pot body, the pot mouth sealing ring abuts against the pot body so that the inner cover and the pot body cooperate to form a cooking cavity, and the air inlet is connected to the cooking cavity.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. In the utility model, the lining cover is provided with a first seal, the free end of the first seal extends toward the inner cover and abuts against the metal cover plate, so that the first seal is used to enclose a heat preservation cavity between the lining cover and the inner cover, and the inner cover is provided with an air inlet connected to the heat preservation cavity. When the steam in the pot rises through the air inlet, it will enter the heat preservation cavity and diffuse in the heat preservation cavity, thereby heating the side of the metal cover plate away from the cooking cavity, so that both the upper and lower sides of the metal cover plate can be directly in contact with the high-temperature steam and thus heated, reducing the temperature difference between the upper and lower sides of the metal cover plate, reducing the occurrence of condensed water on the metal cover plate, reducing the dripping of condensed water when opening the cover, and improving the user experience. At the same time, by making the ratio of the cross-sectional area of ​​the heat preservation cavity to the cross-sectional area of ​​the metal cover plate within the range of 0.5 to 0.9, the heat preservation cavity can have a larger cross-sectional area, so that the steam can slowly diffuse after entering the heat preservation cavity, and increase the circulation time of the steam in the heat preservation cavity, so that the steam can fully exchange heat with the metal cover plate, ensuring the effect of reducing the temperature difference between the upper and lower sides of the metal cover plate. In addition, the metal cover plate is assembled with the fixed bracket surrounding its periphery, and the free end of the first seal is located on the inner side of the fixed bracket, so that the heat preservation cavity is formed in the metal cover plate. The high temperature resistance and thermal conductivity of the metal cover plate are better than those of the fixed bracket. Therefore, the heating efficiency of the steam on the metal cover plate is guaranteed, and the temperature of the upper side of the metal cover plate can be quickly increased, and the temperature difference between the upper and lower sides can be timely reduced, and the high-temperature steam is prevented from directly contacting the fixed bracket, causing the fixed bracket to deform or be damaged under high temperature. In addition, the heat preservation cavity is surrounded by the first seal, so the high-temperature steam can only flow on the inner side of the first seal. The assembly position of the metal cover plate and the fixed bracket is located on the outer side of the first seal, that is, outside the heat preservation cavity, thereby ensuring the cleanliness of the assembly gap between the metal cover plate and the fixed bracket, and preventing condensed water, food soup, etc. from overflowing and accumulating in the assembly gap.

[0020] 2. As a preferred embodiment of the present invention, a positioning groove is provided on the side of the metal cover plate facing the lining cover, and the first seal has a sealing lip, which extends into the positioning groove and abuts against the groove wall of the positioning groove. The sealing lip of the first seal extends into the positioning groove and abuts against the groove wall of the positioning groove, so that the abutment between the sealing lip and the metal cover plate is more stable, and the groove wall of the positioning groove can limit the sealing lip to prevent the sealing lip from shifting and affecting the sealing effect of the insulation chamber. At the same time, when the inner cover is installed on the lining cover, the sealing lip of the first seal and the positioning groove can be used for installation and positioning, which helps users to quickly and conveniently complete the installation of the inner cover and improves the convenience of installation.

[0021] 3. As a preferred embodiment of the utility model, a barrier is provided between the air inlet and the air outlet, and a first flow gap is formed between at least one end of the barrier and the first sealing member. The barrier is located in the heat preservation chamber and between the air inlet and the air outlet, and plays a role in blocking the steam flowing from the air inlet to the air outlet. In this way, on the one hand, the flow path of the high-temperature steam is extended, and the steam is prevented from being discharged directly from the air outlet after entering from the air inlet, and the contact time between the high-temperature steam and the metal cover plate is increased, thereby improving the heating effect on the upper side of the metal cover plate. On the other hand, the steam flowing to the air outlet will collide with the barrier, which will help the rupture of bubbles and liquid bubbles, so that the bubbles that follow the steam to rise into the heat preservation chamber will rupture after colliding with the barrier, and the liquid inside the bubble will fall to the bottom wall of the heat preservation chamber, and the airflow will flow through the first flow gap between the barrier and the first sealing member, thereby improving the bubble breaking and overflow prevention effect, and preventing the soup from overflowing from the exhaust valve of the pot cover during the exhaust process.

[0022] 4. As a preferred embodiment of the utility model, the metal cover plate is also provided with a reflux port connected to the heat preservation chamber. The condensed water and liquids such as food soup in the heat preservation chamber can flow back into the pot through the reflux port, reducing the accumulation of liquid in the heat preservation chamber, ensuring the cleanliness of the heat preservation chamber, and reducing the cleaning pressure of the user.

[0040] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

In the description of this specification, the description with reference to the terms "implementation method", "example", "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 utility model. In this specification, the schematic representation of the above terms does 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.

[0045] like Figure 1 , Figure 3 and Figure 8 As shown, a pot cover assembly comprises a lining cover 1 and an inner cover 2 detachably fixed to the lining cover 1, the inner cover 2 comprises a metal cover plate 21, a pot mouth sealing ring 23 and a fixing bracket 22, the fixing bracket 22 is installed on the outer periphery of the metal cover plate 21, the pot mouth sealing ring 23 is clamped and fixed between the fixing bracket 22 and the metal cover plate 21, the lining cover 1 is provided with a first sealing member 3, the free end of the first sealing member 3 is located on the inner side of the fixing bracket 22 and abuts against the metal cover plate 21 to form a heat preservation cavity 31 between the metal cover plate 21 and the lining cover 1, the inner cover 2 is provided with an air inlet 211 connected to the heat preservation cavity 31, the lining cover 1 is provided with an air outlet 11 connected to the heat preservation cavity 31, wherein the ratio of the cross-sectional area of ​​the heat preservation cavity 31 to the cross-sectional area of ​​the metal cover plate 21 is 0.5 to 0.9. It can be understood that, according to actual needs, the above ratio can be 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, etc., and is not limited here.

[0046] Specifically, the fixing bracket 22 can be made of plastic material, and the fixing bracket 22 is fixedly connected to the metal cover plate 21 by screws, clamping or other means, and the two clamp and fix the pot mouth sealing ring 23.

[0047] It is understandable that the lining cover 1 is also provided with an exhaust channel, which is connected to the insulation chamber 31, so that after the airflow passes through the air inlet 211, it is first diffused and converged in the insulation chamber 31 before entering the exhaust channel, heating the upper side of the metal cover plate 21, and then discharged through the exhaust channel.

[0048] In the utility model, the lining cover 1 is provided with a first sealing member 3, the free end of the first sealing member 3 extends toward the inner cover 2 and abuts against the metal cover plate 21, so that the first sealing member 3 is used to enclose a heat preservation chamber 31 between the lining cover 1 and the inner cover 2, and the inner cover 2 is provided with an air inlet 211 connected to the heat preservation chamber 31. When the steam in the pot rises through the air inlet 211, it will enter the heat preservation chamber 31 and diffuse in the heat preservation chamber 31, so as to heat the side of the metal cover plate 21 away from the cooking chamber, so that the upper and lower sides of the metal cover plate 21 can be directly in contact with the high-temperature steam and thus be heated, thereby reducing the temperature difference between the upper and lower sides of the metal cover plate 21, reducing the occurrence of condensed water on the metal cover plate 21, reducing the dripping of condensed water when opening the cover, and improving the user experience.

[0049] At the same time, by making the ratio of the cross-sectional area of ​​the heat preservation chamber 31 to the cross-sectional area of ​​the metal cover plate 21 within the range of 0.5 to 0.9, the heat preservation chamber 31 can have a larger cross-sectional area, so that the steam can diffuse slowly after entering the heat preservation chamber 31, and increase the circulation time of the steam in the heat preservation chamber 31, so that the steam can fully exchange heat with the metal cover plate 21, ensuring the effect of reducing the temperature difference between the upper and lower sides of the metal cover plate 21. If the above ratio is less than 0.5, the contact area between the steam and the metal cover plate will be relatively small, and the effect of reducing condensed water cannot be achieved; and if the above ratio is greater than 0.9, although it can ensure that the steam can fully contact the metal cover plate 21, it will make the first sealing member 3 too close to the outer periphery of the metal cover plate and the inner peripheral wall of the lining cover where the inner cover is installed, increasing the difficulty of designing and assembling the pot cover assembly.

[0050] In addition, the metal cover plate 21 is assembled with the fixed bracket 22 surrounding its outer periphery, and the free end of the first seal 3 is located inside the fixed bracket 22, so that the heat preservation chamber 31 is formed in the metal cover plate 21. The high temperature resistance and thermal conductivity of the metal cover plate 21 are better than those of the fixed bracket 22. Therefore, the heating efficiency of the steam on the metal cover plate 21 is guaranteed, and the temperature on the upper side of the metal cover plate 21 can be quickly increased, and the temperature difference between the upper and lower sides can be timely reduced, and the high-temperature steam is prevented from directly contacting the fixed bracket 22, so that the fixed bracket 22 is deformed or damaged at high temperature. In addition, the heat preservation chamber 31 is surrounded by the first seal 3, so the high-temperature steam can only flow inside the first seal 3, and the assembly position of the metal cover plate 21 and the fixed bracket 22 is located outside the first seal 3, that is, outside the heat preservation chamber 31, thereby ensuring the cleanliness of the assembly gap between the metal cover plate 21 and the fixed bracket 22, and preventing condensed water, food soup, etc. from overflowing and accumulating in the assembly gap.

[0051] Preferably, the ratio of the cross-sectional area of ​​the insulation cavity to the cross-sectional area of ​​the metal cover is 0.7-0.8, so as to ensure the area of ​​the insulation cavity 31, so that as much area of ​​the metal cover 21 as possible is located in the insulation cavity 31 and is heated by high-temperature steam, so that the temperature of most areas of the metal cover 21 is closer, ensuring the overall effect of reducing condensation water, while not making the first seal 3 too close to the periphery of the metal cover, reducing the difficulty of designing and assembling the pot cover assembly.

[0052] Of course, in some alternative embodiments, since the metal cover 21 corresponds to the cooking cavity, the ratio of the cross-sectional area of ​​the heat preservation cavity to the cross-sectional area of ​​the cooking cavity can also be 0.5 to 0.9.

[0053] As a preferred embodiment of the present invention, refer to Figure 6 and Figure 8 The lining cover 1 is also provided with a temperature measuring member 4, the metal cover plate 21 is provided with an opening 213 corresponding to the temperature measuring member 4, a second sealing member 5 is embedded in the opening 213, the second sealing member 5 has a through hole, and the temperature measuring member 4 passes through the through hole. Such a configuration allows the second sealing member to be disassembled and cleaned together with the inner cover 2, thereby improving the overall cleaning convenience.

[0054] It should be noted that the “through the through hole” may mean that after the temperature measuring component 4 passes through the upper end of the through hole, its lower end is slightly lower than the lower end of the through hole, or the lower end of the temperature measuring component 4 is basically flush with the lower end of the through hole, or the lower end of the temperature measuring component 4 passes through the through hole of the second sealing component 5 and extends under the metal cover plate 21, which is not limited here.

[0055] Furthermore, the present embodiment does not limit the arrangement of the second seal 5, which includes but is not limited to the following examples: in a specific embodiment, the free end of the second seal 5 abuts against the liner 1, so that the first seal 3 and the second seal 5 cooperate to form a closed heat preservation chamber 31; in another specific embodiment, the free end of the second seal 5 does not contact the liner 1, that is, there is an air gap between the free end of the second seal 5 and the liner 1. Of course, the second seal 5 may not be provided with a free end extending upward, which is not limited here.

[0056] Among them, the second sealing member 5 can abut against the peripheral side of the temperature measuring member 4 to seal the gap between the temperature measuring member 4 and the edge of the opening 213. The second sealing member 5 can also not contact the peripheral side of the temperature measuring member 4, so that there is a gap between the temperature measuring member 4 and the opening 213, and the steam in the pot can enter the insulation chamber 31 through the gap.

[0057] Preferably, the free end of the second sealing member 5 does not contact the liner cover 1, and the second sealing member 5 does not contact the peripheral side of the temperature measuring member 4, that is, the heat preservation chamber 31 is connected with the environment in the pot at the second sealing member 5. The steam in the heat preservation chamber 31 can flow back to the pot through this, and the steam in the pot can also enter the heat preservation chamber 31 through this, so as to increase the amount of steam entering the heat preservation chamber 31 per unit time, and improve the steam circulation in the pot and the heat preservation chamber 31, thereby improving the heating effect of the metal cover plate 21.

[0058] In a preferred embodiment, reference Figure 1 and Figure 6 The lining cover 1 is also provided with a temperature measuring component 4, and the inner cover 2 is provided with an opening 213 corresponding to the temperature measuring component 4. A second sealing component 5 surrounding the temperature measuring component 4 is also provided between the lining cover 1 and the metal cover plate 21, and the free end of the second sealing component 5 abuts against the metal cover plate 21.

[0059] On the one hand, the second sealing member 5 surrounds the outer circumference of the temperature measuring member 4, reducing the probability of liquid and food residues in the heat preservation chamber 31 adhering to the temperature measuring member 4, ensuring the cleanliness and detection accuracy of the temperature measuring member 4. On the other hand, the temperature measuring member 4 is located on the inner side of the second sealing member 5 and is in direct contact with the environment in the pot, while the high-temperature steam in the heat preservation chamber 31 will contact the outer side of the second sealing member 5, thereby reducing the temperature difference on both sides of the second sealing member 5, reducing the amount of condensed water generated in the second sealing member 5, and avoiding excessive condensed water adhering to the second sealing member 5 or the temperature measuring member 4, which can also ensure the cleanliness of the temperature measuring member 4 and the accuracy of temperature detection.

[0060] Of course, in some alternative implementations of the present invention, there may be an air gap between the free end of the second sealing member 5 and the metal cover plate 21, which is not limited here.

[0061] As a preferred embodiment of the present invention, Figure 4 , Figure 5 As shown, a positioning groove 214 is provided on the side of the metal cover plate 21 facing the liner cover 1 , and the first sealing member 3 has a sealing lip, which extends into the positioning groove 214 and abuts against the groove wall of the positioning groove 214 .

[0062] The sealing lip of the first sealing member 3 extends into the positioning groove 214 and abuts against the groove wall of the positioning groove 214, so that the abutment between the sealing lip and the metal cover plate 21 is more stable, and the groove wall of the positioning groove 214 can limit the sealing lip to prevent the sealing lip from deviating and affecting the sealing effect of the heat preservation cavity 31. At the same time, when the inner cover 2 is installed on the lining cover 1, the sealing lip of the first sealing member 3 and the positioning groove 214 can be used for installation and positioning, which helps users to quickly and conveniently complete the installation of the inner cover 2 and improves the convenience of installation.

[0063] In addition, as the steam in the insulation chamber 31 increases, the air pressure in the insulation chamber 31 increases. Under the action of the air pressure difference inside and outside the insulation chamber 31, the sealing lip will tend to swing outward, thereby making the sealing lip tightly abut against the outer groove wall of the positioning groove 214, thereby improving the contact effect between the two and enhancing the sealing performance.

[0064] It should be noted that the present invention does not limit the cross-sectional shape of the positioning groove 214. In one embodiment, Figure 5 As shown, the bottom wall of the positioning groove 214 is a plane, and the groove walls on both sides extend vertically upward. Of course, the groove walls on both sides can also be extended upwardly at an angle, so that the positioning groove 214 is an open shape, which plays a guiding role in the cooperation of the sealing lip. In other embodiments, the cross section of the positioning groove 214 can also be an arc shape as a whole, etc., which is not limited here.

[0065] As a preferred embodiment of the present invention, Figure 2 As shown, a barrier member 6 is provided between the air inlet 211 and the air outlet 11 , and a first flow gap 61 is formed between at least one end of the barrier member 6 and the first sealing member 3 .

[0066] The barrier 6 is located in the heat preservation chamber 31 and between the air inlet 211 and the air outlet 11, and plays a role in blocking the steam flowing from the air inlet 211 to the air outlet 11. In this way, on the one hand, the flow path of the high-temperature steam is extended to prevent the steam from entering from the air inlet 211 and being discharged directly from the air outlet 11, thereby increasing the contact time between the high-temperature steam and the metal cover plate 21, thereby improving the heating effect on the upper side of the metal cover plate 21. On the other hand, the steam flowing to the air outlet 11 will collide with the barrier 6, which will help the rupture of bubbles and liquid bubbles, so that the bubbles that follow the steam to rise into the heat preservation chamber 31 will rupture after colliding with the barrier 6, and the liquid inside the bubbles will fall to the bottom wall of the heat preservation chamber 31, and the airflow will flow through the first flow gap 61 between the barrier 6 and the first sealing member 3, thereby improving the bubble breaking and overflow prevention effect, and preventing the soup from overflowing from the exhaust valve of the pot cover during the exhaust process.

[0067] Preferably, if Figure 2 and Figure 6 As shown, the air inlet 211 and the air outlet 11 are arranged relatively on both sides of the barrier 6 to further extend the flow path of the steam in the insulation chamber 31 and allow as much air flow as possible to pass through the first flow gap 61, further improving the effect of reducing condensation water and preventing bubble breakage and overflow.

[0068] Preferably, the direction of the airflow from the air inlet 211 to the air outlet 11 is defined as a first direction, and the extending direction of the barrier 6 is perpendicular to the first direction, so as to better block the airflow and steam in the heat preservation chamber 31. Figure 2As shown, there is a first flow gap 61 between both ends of the barrier 6 and the first sealing member 3, so that steam can flow through both sides of the barrier 6. Of course, the first flow gap 61 can also be formed between one end of the barrier 6 and the first sealing member 3, and the other end has no gap, so that steam flows fixedly from one side, which is not limited here.

[0069] This embodiment does not limit the location and arrangement of the barrier 6, which may be one of the following embodiments:

[0070] Embodiment 1: In this embodiment, as Figure 2 As shown, the barrier 6 is disposed on the liner 1 and extends toward the metal cover plate 21. The lower end of the barrier 6 abuts against the metal cover plate 21, or a second flow gap is provided between the lower end of the barrier 6 and the metal cover plate 21.

[0071] A second flow gap is formed between the lower end of the barrier 6 and the metal cover plate 21, so that the chamber on the side of the barrier 6 facing the air inlet 211 and the chamber on the side of the barrier 6 facing the air outlet 11 are connected not only through the first flow gap 61, but also through the second flow gap. While ensuring a certain bubble breaking effect, the connecting area is increased, so that the steam in the insulation chamber 31 can flow toward the air outlet 11 more smoothly, thereby ensuring the exhaust efficiency.

[0072] Embodiment 2: In this embodiment, the barrier 6 is disposed on the metal cover plate 21 and extends toward the liner 1. The upper end of the barrier 6 abuts against the liner 1, or a second flow gap is provided between the upper end of the barrier 6 and the liner 1.

[0073] Of course, in some other embodiments, such as Figure 2 As shown, a matching notch 62 is provided at one end of the barrier 6 close to the lining cover 1, and the matching notch 62 cooperates with the lining cover 1 to form a second flow gap; or, a flow port is opened at one end of the barrier 6 close to the lining cover 1.

[0074] By assembling the gap or providing the flow opening in the barrier 6, the communication area of ​​the chambers on both sides of the barrier 6 is also increased, and the air flow efficiency on both sides is improved while ensuring the bubble breaking effect, and the exhaust efficiency is improved.

[0075] In a preferred embodiment, reference Figure 6 and Figure 7 The lining cover 1 is also provided with a temperature measuring element 4 , and the inner cover 2 is provided with an opening 213 corresponding to the temperature measuring element 4 , the opening 213 constitutes an air inlet 211 , and a baffle rib 7 is provided between the opening 213 and the air outlet 11 .

[0076] In the present embodiment, the opening 213 constitutes the air inlet 211, so that the opening 213 not only serves to allow the temperature measuring component 4 to pass through, but also serves to connect the environment inside the pot with the heat preservation chamber 31. It has multiple uses, reduces the number of openings on the metal cover plate 21, simplifies the structure of the metal cover plate 21, and reduces the processing difficulty.

[0077] At the same time, a baffle rib 7 is provided between the opening 213 and the air outlet 11, so that the steam needs to flow along the baffle rib 7 and can only flow to the air outlet 11 after crossing the baffle rib 7, thereby increasing the flow path of the steam, prolonging the contact time between the steam and the metal cover plate 21, and improving the heating effect.

[0078] Preferably, if Figure 7 As shown, the baffle rib 7 surrounds a portion of the outer periphery of the opening 213, and the baffle rib 7 has a notch 71, so that the steam can only flow through the notch 71 to the air outlet 11. Furthermore, the notch 71 faces away from the air outlet 11 to further increase the steam flow path.

[0079] In a preferred embodiment, Figure 4 As shown, the metal cover plate 21 is further provided with a return port 212 communicating with the heat preservation chamber 31 .

[0080] The condensed water and liquids such as food soup in the heat preservation chamber 31 can flow back into the pot through the reflux port 212, thereby reducing the accumulation of liquid in the heat preservation chamber 31, ensuring the cleanliness of the heat preservation chamber 31, and reducing the cleaning pressure of the user.

[0081] The utility model also discloses a cooking utensil, including a pot body and the above-mentioned pot cover assembly. When the pot cover assembly covers the pot body, the pot mouth sealing ring 23 abuts against the pot body so that the inner cover 2 and the pot body cooperate to form a cooking cavity, and the air inlet 211 is connected to the cooking cavity.

[0082] The air inlet 211 connects the cooking cavity with the heat preservation cavity 31, so that the high-temperature steam in the cooking cavity can reach the heat preservation cavity 31 through the air inlet 211, contact the upper side of the metal cover plate 21 to heat it, thereby reducing the temperature difference between the upper and lower sides of the metal cover plate 21, and effectively reducing the generation of condensation water on the metal cover plate 21.
