Description

Technical Field

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

[0002] Cooking utensils typically have a steam valve on the lid to release gas from the pot during or after cooking to balance the pressure inside and outside the pot. However, during the venting process, due to the high kinetic energy of the gas or the boiling water in the pot, liquid and foam in the pot can rise with the gas to the steam valve and then be ejected from the steam valve, causing overflow and contamination of the lid, affecting the user experience. Due to the limitations of the lid's structure and size, the steam valve is usually located at a low height, that is, close to the cooking chamber. This makes it easier for liquid in the cooking chamber to enter the steam valve, exacerbating the risk of overflow.

[0003] In the prior art, some cooking utensils are equipped with an air pump on the pot lid. During the exhaust process, the air pump blows cold air from the outside into the pot, so that the cold air mixes with the hot air flow in the pot, accelerates the bursting of bubbles and foam carried in the air flow, and then completes the gas-liquid separation. The gas then enters the steam valve and is discharged, thereby achieving the effect of breaking bubbles and preventing overflow.

[0004] However, while the above solution can achieve a certain degree of overflow prevention, it also has certain shortcomings. First, the air pump blows cold air directly into the cooking chamber. Although the cold air can mix with the hot air flow to break bubbles, the cold air entering the cooking chamber will inevitably cause the temperature inside the cooking chamber to drop rapidly. After the cold air comes into contact with the food, the temperature of the food will also be rapidly lowered. If the air is exhausted during the cooking process, the entry of cold air will directly affect the heating efficiency, thereby increasing the cooking time. If the air is exhausted after cooking, the insulation effect will be affected, causing the food in the cooking chamber to cool prematurely, affecting the user experience.

[0005] Furthermore, the cool air inlet and the steam valve are typically located on the left and right sides of the pot lid, respectively, and are quite far apart. Consequently, when the cool air enters the pot and flows from the top of the cooking chamber toward the steam valve, the rice slurry formed by the broken bubbles can adhere to the top wall of the cooking chamber, i.e., the pot lid, causing sanitation problems. Furthermore, due to the long flow path, the rice slurry contaminates a relatively large area of ​​the pot lid, further increasing the cleaning burden on the user. Utility Model Content

[0006] The utility model provides a cooking utensil, which solves the problem that the pot overflows easily during the exhaust process of the existing cooking utensil, and solves the problem that blowing cold air into the cooking cavity will reduce the heating efficiency and the pot cover is easily contaminated by rice slurry when the bubbles are broken.

[0007] The technical solution adopted by this utility model is:

[0008] A cooking utensil comprises a pot body and a pot lid covering the pot body, the pot lid comprising a lid body and an inner lid located below the lid body, the lid body being provided with a steam valve, the inner lid and the pot body cooperating to form a cooking cavity, a mixing cavity surrounded by a seal being provided between the lid body and the inner lid, the mixing cavity being connected to the cooking cavity through the inner lid, the top of the mixing cavity being connected to the steam valve, the lid body being further provided with an air pump, the air pump being connected to the mixing cavity to supply a cold air flow into the mixing cavity.

[0009] The cooking utensil of the present invention also has the following additional technical features:

[0010] The top wall of the mixing chamber is provided with a cold air inlet connected to the air pump, the inner cover has a matching area corresponding to the mixing chamber, the matching area is provided with a cold air outlet, and the cold air inlet and the cold air outlet are correspondingly arranged up and down.

[0011] The matching area is also provided with an air outlet connecting the cooking cavity and the steam valve. The lateral distance between the air outlet and the cold air outlet is L, where 20mm≤L≤50mm.

[0012] The matching area is also provided with an overflow port, which is adjacent to the cold air overflow port, and the diameter of the overflow port is smaller than the diameter of the cold air overflow port.

[0013] The mixing chamber extends radially of the pot cover to have a proximal end close to the center of the pot cover and a distal end away from the center of the pot cover, the air pump is communicated with the mixing chamber at the proximal end, and the mixing chamber is communicated with the steam valve at the distal end.

[0014] The inner cover has a matching area corresponding to the mixing cavity. The matching area is provided with a guide slope and a bottom plane located at the lower end of the guide slope. The bottom plane is provided with an opening connecting the cooking cavity and the steam valve.

[0015] The cover body is also provided with a temperature measuring piece, and the inner cover is provided with a through hole, through which the temperature measuring piece extends into the cooking cavity, and the through hole is located outside the mixing cavity.

[0016] The inner cover is detachably connected to the cover body. The cooking utensil further comprises a fixing member located between the inner cover and the cover body. The fixing member is fixedly connected to the lower surface of the cover body so that the cover body and the fixing member clamp the fixing seal.

[0017] The fixing member is provided with a first pair of interfaces connected to the air pump and a second pair of interfaces connected to the steam valve. A wind shield rib protruding toward the mixing chamber is provided between the first pair of interfaces and the second pair of interfaces.

[0018] A cold air inlet is provided above the mixing chamber, the steam valve has a steam inlet located at the top of the mixing chamber, the inner cover has a matching area corresponding to the mixing chamber, the matching area is provided with a connecting port, and the upward projection of the connecting port covers the cold air inlet and the steam inlet.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0020] 1. In the present invention, a seal is provided between the lid and the inner lid, which enclose a mixing chamber between the lid and the inner lid. The lower portion of the mixing chamber is connected to the cooking chamber, and the steam valve is located above the mixing chamber. This up-down layout design raises the height at which the fluid in the cooking chamber rises to the steam valve, extending the flow path, thereby allowing the fluid more time to break bubbles and complete gas-liquid separation, making it difficult for liquid and foam to enter the steam valve.

[0021] Furthermore, the air pump is connected to the mixing chamber, allowing the cold airflow to flow preferentially into the mixing chamber rather than directly into the cooking chamber. During the exhaust process, the hot air in the cooking chamber continuously flows into the mixing chamber, where the cold and hot air mix and break bubbles first. Only a portion of the cold airflow passes through the mixing chamber and enters the cooking chamber, where it mixes with the air inside the cooking chamber and further breaks bubbles. This reduces the amount of cold air entering the cooking chamber, thereby minimizing its impact on heating and heat preservation efficiency.

[0022] Furthermore, the entry of the cold airflow and the discharge of the hot gas from the pot occur within the mixing chamber enclosed by the seal, making the space for the cold and hot airflows to mix relatively small. Furthermore, after the cold airflow enters, the path it takes to the steam valve is also relatively short, thus reducing the risk of rice slurry contamination of the inner cover. Even if rice slurry adheres to the inner cover, it will only contaminate the relatively small area between where the cold air enters and where the gas from the pot is discharged. The area outside the mixing chamber of the inner cover is also less susceptible to rice slurry adhesion, as there is no cold airflow. Furthermore, because the mixing chamber is relatively small and the airflow is relatively fast, the flow of air can also flush any rice slurry adhering to the surface of the inner cover, thus achieving a self-cleaning effect.

[0023] 2. As a preferred embodiment of the present invention, the top wall of the mixing chamber is provided with a cold air inlet connected to the air pump, and the inner cover has a matching area corresponding to the mixing chamber, and the matching area is provided with a cold air outlet, and the cold air inlet and the cold air outlet are arranged in correspondence with each other up and down. After the cold air flow enters the mixing chamber from top to bottom, two flow paths are formed. One path is that the cold air flow passes downward through the cold air outlet and enters the cooking chamber, and then flows horizontally toward the steam valve. During this process, it contacts the hot air flow to break bubbles, and then rises with the hot air flow and enters the mixing chamber again from the other end of the mixing chamber, and then is discharged through the steam valve. The other path is that after the cold air flow enters the mixing chamber, it flows horizontally in the mixing chamber to the steam valve. During this process, it contacts the hot air flow entering the mixing chamber to break bubbles, and rises with the hot air flow to enter the steam valve and be discharged. The combined breaking of bubbles through the above two paths can make the cold air flow more fully contact the rising hot air flow, thereby further accelerating the bursting of bubbles. At the same time, high-speed airflow passes through the upper and lower sides of the inner cover corresponding to the mixing chamber, which can flush the upper and lower sides of the inner cover to prevent a large amount of rice slurry from accumulating on the surface of the inner cover.

[0024] 3. As a preferred embodiment of the present invention, the mixing chamber extends radially along the pot lid to have a proximal end close to the center of the pot lid and a distal end away from the center of the pot lid. The air pump is connected to the mixing chamber at the proximal end, and the mixing chamber is connected to the steam valve at the distal end. The proximal end of the mixing chamber is closer to the center of the pot lid, that is, the center of the cooking chamber, and the center of the cooking chamber is a heat accumulation area. Therefore, the temperature at the proximal end is relatively high, and the cold air flow enters the mixing chamber from here, so that the temperature difference between the cold air flow and the hot air flow in the pot is large, which is more conducive to the bursting of bubbles, thereby improving the bubble breaking effect. The distal end is away from the center of the pot lid, and the temperature here is relatively low, and the boiling degree of the liquid in the pot is relatively weak. Therefore, the hot air flow in the pot enters the mixing chamber and enters the steam valve from here, which can reduce the amount of foam and bubbles carried in the air flow, thereby reducing the risk of overflow.

[0025] 4. As a preferred embodiment of the present invention, the inner lid has a mating area corresponding to the mixing chamber. The mating area is provided with a guide slope and a bottom plane located at the lower end of the guide slope. The bottom plane has an opening connecting the cooking chamber and the steam valve. The provision of the guide slope can, on the one hand, guide the cold airflow entering the mixing chamber toward the steam valve, thereby mixing with the upwelling hot airflow. On the other hand, after the bubbles burst in the mixing chamber, the resulting liquid can flow toward the bottom plane under the guidance of the guide slope, and ultimately flow back into the cooking chamber through the opening in the bottom plane. At the same time, the opening is used not only for the backflow of liquid in the mixing chamber, but also for the upwelling of airflow in the cooking chamber into the mixing chamber, thereby achieving multiple uses, simplifying the structure of the inner lid, reducing the number of openings, and reducing the difficulty of processing.

[0026] 5. As a preferred embodiment of the present invention, a cold air inlet is provided above the mixing chamber, the steam valve has a steam inlet located at the top of the mixing chamber, the inner cover has a matching area corresponding to the mixing chamber, the matching area is provided with a connecting port, and the upward projection of the connecting port covers the cold air inlet and the steam inlet. After the cold air flow enters the mixing chamber, it directly enters the cooking chamber through the connecting port, mixes with the hot air flow in the cooking chamber, and breaks bubbles, and then enters the steam inlet together with the hot air flow. In this embodiment, after the foam and bubbles carried by the hot air flow come into contact with the cold air flow, the rice slurry, condensed water, etc. formed by the rupture will directly fall back into the cooking chamber, and will not accumulate in the mixing chamber and the surface of the inner cover, thereby ensuring the cleanliness of the inner cover.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. 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. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0051] 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.

[0052] like Figure 1 、 Figure 2 As shown, a cooking utensil includes a pot body and a pot cover covering the pot body, the pot cover includes a lid body 1 and an inner cover 2 located below the lid body 1, the lid body 1 is provided with a steam valve 3, the inner cover 2 and the pot body cooperate to form a cooking cavity 21, a mixing cavity 12 surrounded by a seal 6 is provided between the lid body 1 and the inner cover 2, the mixing cavity 12 is connected to the cooking cavity 21 through the inner cover 2, and the top of the mixing cavity 12 is connected to the steam valve 3, the lid body 1 is also provided with an air pump 4, the air pump 4 is connected to the mixing cavity 12 to supply a cold air flow into the mixing cavity 12.

[0053] In the present invention, a sealing member 6 is provided between the cover body 1 and the inner cover 2. The sealing member 6 forms a mixing chamber 12 between the cover body 1 and the inner cover 2. The bottom of the mixing chamber 12 is connected to the cooking chamber 21. The steam valve 3 is located above the mixing chamber 12. This upper and lower layout structure design raises the height of the fluid in the cooking chamber 21 rising to the steam valve 3, extends the flow path, and thereby provides the fluid with more sufficient time to break bubbles and complete gas-liquid separation, so that liquid and foam are not easily able to enter the steam valve 3.

[0054] Furthermore, the air pump 4 is connected to the mixing chamber 12, allowing the cold airflow to flow preferentially into the mixing chamber 12 rather than directly into the cooking chamber 21. During the exhaust process, the high-temperature air in the cooking chamber 21 continuously flows into the mixing chamber 12, where the cold airflow and the high-temperature air preferentially mix and break bubbles in the mixing chamber 12. Only a portion of the cold airflow passes through the mixing chamber 12 into the cooking chamber 21, where it mixes with the air in the cooking chamber 21 and further breaks bubbles. This reduces the amount of cold air entering the cooking chamber 21, thereby minimizing its impact on heating and heat preservation efficiency.

[0055] Moreover, the entry of the cold air flow and the discharge of the high-temperature gas in the pot are both carried out in the mixing chamber 12 surrounded by the seal 6, so that the space for the cold and hot air flows to mix is ​​relatively small, and after the cold air flow enters, the path it flows to the steam valve 3 is also relatively short, thereby reducing the contamination of the inner cover 2 by rice slurry. Even if rice slurry adheres to the inner cover 2, it will only contaminate the smaller area between the cold air entry position and the gas discharge position in the pot. The area outside the mixing chamber 12 of the inner cover 2 is not easy to adhere to rice slurry because there is no cold air flow. At the same time, since the mixing chamber 12 is small and the air flow speed is fast, the rice slurry attached to the surface of the inner cover 2 can also be flushed by the flow of air, thereby achieving a self-cleaning effect.

[0056] Furthermore, because the mixing chamber 12 and the steam valve 3 are connected, the temperature inside the mixing chamber 12 is somewhat different from that in other areas of the inner cover 2. During boiling, foam and steam condense and flow back, minimizing the risk of blockage of the cold air inlet 121. Furthermore, because the mixing chamber 12 and the steam valve 3 are connected, the steam valve 3 is connected to the outside atmosphere. Even if excessive liquid overflows into the mixing chamber 12, the pressure in the direction of the steam valve 3 is low, causing the liquid and foam to preferentially flow toward the steam valve 3 without blocking the cold air inlet 121.

[0057] It should be noted that the present invention does not limit the assembly method of the inner cover 2. In a preferred embodiment, the inner cover 2 is detachably fixed to the cover body 1, so that the user can clean the inner cover 2 separately. Specifically, the seal 6 is fixed to the cover body 1. When the user installs the inner cover 2 to the cover body 1, the lower end of the seal 6 and the inner cover 2 are re-abutted, enclosing the mixing chamber 12. Of course, the inner cover 2 can also be designed to be non-detachable, which is not limited here.

[0058] As a preferred embodiment of the present invention, Figures 2 to 4 As shown, the top wall of the mixing chamber 12 is provided with a cold air inlet 121 connected to the air pump 4, and the inner cover 2 has a matching area 24 corresponding to the mixing chamber 12. The matching area 24 is provided with a cold air outlet 22, and the cold air inlet 121 and the cold air outlet 22 are correspondingly arranged up and down.

[0059] The cold air outlet 22 and the cold air inlet 121 are arranged correspondingly above and below each other, which can reduce the resistance of cold air entering the cooking cavity 21 and ensure that most of the cold air enters the cooking cavity 21 through the cold air outlet 22.

[0060] After the cold airflow enters the mixing chamber 12 from top to bottom, two flow paths are formed, such as Figure 3 As shown, one of the paths is that the cold air flows downward through the cold air outlet 22 into the cooking chamber 21, and then flows horizontally toward the steam valve 3. During this process, it contacts the hot air flow to break the bubbles, and then flows upward together with the hot air flow to re-enter the mixing chamber 12 from the other end of the mixing chamber 12, and then is discharged through the steam valve 3. Figure 4 As shown, the other path is that after the cold air flow enters the mixing chamber 12, it flows horizontally in the mixing chamber 12 to the steam valve 3. During this process, it contacts the hot air flow entering the mixing chamber 12 and breaks the bubbles, and then rises together with the hot air flow into the steam valve 3 and is discharged. By combining the above two paths to break the bubbles, the cold air flow can be more fully contacted with the rising hot air flow, thereby further accelerating the bursting of the bubbles. At the same time, high-speed airflow passes through the upper and lower sides of the inner cover 2 corresponding to the mixing chamber 12, and then the upper and lower sides of the inner cover 2 can be flushed to prevent the rice slurry from accumulating in large quantities on the surface of the inner cover 2.

[0061] Furthermore, if Figure 7 As shown, the matching area 24 is further provided with an air outlet 23 communicating with the cooking cavity 21 and the steam valve 3. The lateral distance between the air outlet 23 and the cold air outlet 22 is L, wherein 20 mm ≤ L ≤ 50 mm.

[0062] If the lateral distance L is too small, the cold air will have a short path to the steam valve 3 after entering, and the cold air will be discharged from the steam valve 3 before the bubble-breaking effect is fully exerted. If the lateral distance L is too large, the cold air in the mixing chamber 12 will have a long path to the steam valve 3, and the air layer formed by the cold air flowing along the surface of the inner cover 2 will be thin. During the bubble breaking process, a large amount of rice slurry will remain on the inner cover 2. When the lateral dimension meets the requirements of 20mm-50mm, the cold air layer can reach the ideal thickness, allowing the rice slurry to fall directly into the cooking chamber 21. The short cold air path results in a fast flow rate, which can self-clean the rice slurry stuck to the inner cover 2.

[0063] Preferably, if Figure 6 As shown, the matching area 24 is further provided with an overflow port 221 . The overflow port 221 is disposed adjacent to the cold air overflow port 22 , and the diameter of the overflow port 221 is smaller than that of the cold air overflow port 22 .

[0064] A large number of bubbles will be generated during the cooking process in the pot, so there is a certain pressure in the cooking cavity 21. The cold air flow will encounter a certain resistance when entering the cooking cavity 21 from the mixing cavity 12, resulting in part of the cold air flow being retained in the mixing cavity 12 and unable to enter the cooking cavity 21. By providing an overflow port 221 near the cold air overflow port 22, the cold air flow retained in the mixing cavity 12 can enter the cooking cavity 21 through the overflow port 221 and then flow toward the air outlet 23.

[0065] like Figure 6 As shown, there are multiple flow outlets 221 , and they are arranged on both sides of the cold air outlet 22 .

[0066] Preferably, if Figure 3 、 Figure 4 As shown, the mixing chamber 12 extends radially along the pot cover to have a proximal end close to the center of the pot cover and a distal end away from the center of the pot cover, the air pump 4 is connected to the mixing chamber 12 at the proximal end, and the mixing chamber 12 is connected to the steam valve 3 at the distal end.

[0067] The proximal end of the mixing chamber 12 is closer to the center of the pot lid, i.e., the center of the cooking chamber 21. Since the center of the cooking chamber 21 is a heat-collecting area, the temperature at the proximal end is relatively high. The cold airflow enters the mixing chamber 12 from this point, creating a larger temperature difference between the cold airflow and the hot airflow within the pot, which further facilitates the bursting of bubbles and improves the bubble-breaking effect. Meanwhile, the far end, located away from the center of the pot lid, has a relatively low temperature and the boiling level of the liquid within the pot is relatively low. Therefore, the hot airflow from the pot enters the mixing chamber 12 and then the steam valve 3 from this point, reducing the amount of foam and bubbles carried in the airflow and, in turn, the risk of overflow.

[0068] Specifically, such as Figure 2 、 Figure 6 As shown, the lid 1 is further provided with a temperature measuring element 11, and the inner lid 2 is provided with a through-hole 25. The temperature measuring element 11 passes through the through-hole 25 to extend into the cooking cavity 21. The through-hole 25 is located outside the mixing cavity 12. The location of the temperature measuring element 11 outside the mixing cavity 12 not only prevents the cold air flow from directly acting on the temperature measuring element 11 and affecting its detection accuracy, but also prevents the rice slurry formed by the bursting of bubbles in the mixing cavity 12 from adhering to the surface of the temperature measuring element 11 and affecting its detection sensitivity.

[0069] Specifically, such as Figure 2 、 Figure 6 As shown, the mixing chamber 12 is located on one side of the temperature measuring element 11 and extends radially along the pot cover.

[0070] As a preferred embodiment of the present invention, Figure 4 、 Figure 6 、 Figure 7As shown, the inner cover 2 has a matching area 24 corresponding to the mixing chamber 12. The matching area 24 is provided with a guide slope 241 and a bottom plane 242 located at the lower end of the guide slope 241. The bottom plane 242 is provided with an opening connecting the cooking chamber 21 and the steam valve 3.

[0071] The setting of the guide slope 241 can, on the one hand, guide the cold air flow entering the mixing chamber 12, so that it flows toward the steam valve 3 and then mixes with the upwelling hot air flow. On the other hand, after the bubbles burst in the mixing chamber 12, the formed liquid can flow toward the bottom plane 242 under the guidance of the guide slope 241, and finally flow back to the cooking chamber 21 through the opening on the bottom plane 242.

[0072] In one embodiment, the bottom plane 242 is further provided with an air outlet 23 connected to the steam valve 3. The hot air in the cooking cavity 21 flows into the mixing cavity 12 through the air outlet 23 and then into the steam valve 3. The liquid in the mixing cavity 12 flows back into the cooking cavity 21 through the opening. In another embodiment, Figure 6 As shown, the opening constitutes an air outlet 23, so that the opening is not only used for the liquid backflow in the mixing chamber 12, but also for the air flow in the cooking chamber 21 to flow up into the mixing chamber 12, thereby achieving multiple uses, simplifying the structure of the inner cover 2, reducing the number of openings, and reducing the difficulty of processing.

[0073] In a preferred embodiment, Figure 1 、 Figure 8 、 Figure 9 As shown, the inner cover 2 is detachably connected to the cover body 1, and the cooking utensil further includes a fixing member 5 located between the inner cover 2 and the cover body 1, and the fixing member 5 is fixedly connected to the lower surface of the cover body 1 so that the cover body 1 and the fixing member 5 clamp the fixing seal 6.

[0074] The fixing member 5 cooperates with the lower surface of the cover body 1 to clamp and fix the sealing member 6, thereby fixing the sealing member 6 to the cover body 1. Even if the inner cover 2 is removed, the sealing member 6 remains stable in position, and the mixing chamber 12 is opened. The user can also clean the inside of the mixing chamber 12 and the sealing member 6, thereby facilitating cleaning while ensuring sealing stability.

[0075] Specifically, such as Figure 1 、 Figure 5 As shown, the cover body 1 is provided with a mounting opening 13 , and the fixing member 5 is fixed in the mounting opening 13 and blocks the mounting opening 13 .

[0076] Furthermore, if Figure 8 、 Figure 9 As shown, the fixing member 5 is provided with a first docking port 52 connected to the air pump 4 and a second docking port 53 connected to the steam valve 3, and a wind shield rib 51 protruding toward the mixing chamber 12 is provided between the first docking port 52 and the second docking port 53.

[0077] The structures for docking with the air pump 4 and the steam valve 3 are all provided on the fixing member 5, so that the fixing member 5 can be processed and manufactured separately without processing the docking structure on the cover body 1, thereby reducing the difficulty of processing. At the same time, the provision of the wind shield 51, on the one hand, can form a certain obstruction to the cold air flow entering the mixing chamber 12, preventing the cold air flow from entering the mixing chamber 12 without sufficient contact with the hot air flow and directly flowing to the steam valve 3. The cold air flow can only pass over the wind shield 51, thereby extending the flow path of the cold air flow and increasing the mixing time of the cold air flow and the hot air flow. On the other hand, the wind shield 51 can also block the hot air flow entering the mixing chamber 12 from flowing toward the cold air inlet 121, reducing the resistance when the cold air enters, and can prevent bubbles from bursting at the cold air inlet 121, thereby preventing the rice slurry produced from blocking the cold air inlet 121.

[0078] like Figure 10 、 Figure 11 As shown, a cold air inlet 121 is provided above the mixing chamber 12, the steam valve 3 has a steam inlet 31 located at the top of the mixing chamber 12, the inner cover 2 has a matching area 24 corresponding to the mixing chamber 12, and the matching area 24 is provided with a connecting port 26, and the upward projection of the connecting port 26 covers the cold air inlet 121 and the steam inlet 31.

[0079] After entering the mixing chamber 12, the cold airflow directly enters the cooking chamber 21 through the connecting port 26, where it mixes with the hot airflow and breaks into bubbles, before entering the steam inlet 31 along with the hot airflow. In this embodiment, the foam and bubbles carried by the hot airflow burst upon contact with the cold airflow, and the resulting rice slurry, condensed water, etc., fall directly back into the cooking chamber 21, avoiding accumulation in the mixing chamber 12 or on the surface of the inner lid 2, thereby ensuring the cleanliness of the inner lid 2.

[0080] like Figure 12 As shown, the bottom of the steam valve 3 is provided with a steam inlet 31, and the top wall is provided with a steam outlet 32. The two are staggered up and down, and there is a steam retaining rib 36 between the two. At the same time, the outer periphery of the steam inlet 31 is also provided with a convex rib 33 protruding into the interior of the steam valve 3 to form an air intake channel 34. The air intake channel 34 has an outlet 35, and the outlet 35 is away from the direction of the steam outlet 32 ​​to further lengthen the flow path of the airflow inside the steam valve 3, so that the bubbles burst during the flow process, thereby reducing the risk of liquid overflow.
