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] Cooking utensils (such as rice cookers, pressure cookers, etc.) are equipped with steam valves on the lids to discharge gas and steam from the pot during or after cooking. However, when cooking soups and porridges, since the liquid is relatively viscous, a large number of bubbles will rise into the steam valve along with the gas after boiling, and then spray out through the steam valve, causing overflow. After the soup is sprayed out of the steam valve, it will remain on the surface of the lid, causing contamination of the lid, increasing the cleaning pressure on the user, and there is also the risk of clogging the steam valve, resulting in the steam valve being unable to vent normally.

[0003] In the prior art, some cooking utensils lengthen the flow path of the fluid by designing the airflow channel inside the steam valve into a tortuous structure, thereby reducing the kinetic energy of the fluid and facilitating the bursting of bubbles. However, it is not possible to squeeze the bubbles simply by lengthening the airflow channel, and thus in actual use, the bubble breaking effect of the existing steam valve is not ideal, especially when the amount of bubbles is large, the bubbles will pass through the airflow channel with the rapid flow of gas, and then spray out of the steam valve, causing overflow. Utility Model Content

[0004] The utility model provides a pot cover assembly and a cooking utensil to solve the problem that the interior of the existing steam valve cannot squeeze bubbles, resulting in poor bubble breaking effect and easy pot overflow.

[0005] The technical solution adopted by the utility model is:

[0006] A pot cover assembly comprises a cover body and an inner cover, a steam valve is arranged between the cover body and the inner cover, a steam pipe and a steam chamber are arranged in the steam valve, the steam pipe has an air inlet and an air outlet, the air inlet is connected to a cooking chamber, the air outlet is connected to the steam chamber, and bubble-breaking convex patterns are arranged at the air outlet and / or on the inner wall of the steam chamber.

[0007] The pot cover assembly of the utility model also has the following additional technical features:

[0008] The edge of the air outlet is provided with convex ribs protruding toward the inside of the steam pipe or toward the inside of the air outlet to form bubble-breaking convex patterns.

[0009] The steam pipe has a top wall to close the top of the steam pipe, and the gas outlet faces horizontally or tilted upward.

[0010] The cover body is provided with an exhaust port connected to the steam chamber, the exhaust port and the steam pipe are arranged in a staggered manner, and the air outlet faces the direction of the steam pipe away from the exhaust port.

[0011] The cover body is provided with an exhaust port connected to the steam chamber, the exhaust port and the steam pipe are arranged in a staggered manner, a steam retaining rib is arranged between the steam pipe and the exhaust port, and the bubble breaking convex pattern is arranged on the steam retaining rib.

[0012] The steam barrier rib is arranged on the cover body and extends downward, the lower edge of the steam barrier rib is lower than the height of the air outlet, and the bubble-breaking convex pattern is arranged on the wall of the steam barrier rib facing the steam pipe; or, the bubble-breaking convex pattern is arranged at the lower end of the steam barrier rib.

[0013] The top wall of the steam chamber is provided with a bubble breaking area correspondingly located above the steam pipe, and the bubble breaking convex pattern is arranged in the bubble breaking area.

[0014] The steam chamber is provided with steam baffles, which divide the steam chamber into a bubble breaking chamber and an exhaust chamber. The bubble breaking area constitutes the top wall of the bubble breaking chamber, and the steam pipe extends into the bubble breaking chamber.

[0015] The inner cover is provided with an installation port, the installation port is provided with a valve seat and a sealing member, the cover body is provided with a downwardly extending mating rib, the mating rib abuts and seals with the sealing member so that the mating rib, the sealing member and the valve seat cooperate to form a steam valve, and the bubble-breaking convex pattern is provided on the valve seat and / or the cover body.

[0016] The utility model also discloses a cooking utensil, comprising a pot body with a cooking cavity and the pot cover assembly, wherein the air inlet is communicated with the cooking cavity, and at least a part of the steam valve is detachably fixed to the pot cover assembly.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0018] 1. In the utility model, the gas in the cooking cavity enters the steam pipe through the air inlet, enters the steam chamber through the air outlet of the steam pipe, and is finally discharged from the steam chamber. The air outlet and / or the inner wall of the steam chamber are provided with bubble-breaking convex patterns, that is, the bubble-breaking convex patterns are arranged on the flow path of the fluid and protrude toward the inside of the channel. When the gas carries bubbles through the air outlet and / or the bubble-breaking convex patterns arranged on the inner wall of the steam chamber, the bubble-breaking convex patterns can squeeze the bubbles, thereby further facilitating the bubble to burst. At the same time, the flow area of ​​the position where the bubble-breaking convex patterns are arranged is reduced. When the airflow passes through, it will collide with the bubble-breaking convex patterns, and then the bubble bursting can also be accelerated under the action of the impact force. In this way, by setting the bubble-breaking convex patterns, the bubbles are subjected to squeezing force and impact force when passing through, which greatly improves the bubble-breaking efficiency and bubble-breaking effect, helps the bubbles to complete the bursting before reaching the exhaust port of the steam chamber, and then makes the liquid complete the reflux in the steam valve, greatly reduces the risk of bubbles and liquid spraying out from the exhaust port of the steam valve, alleviates the occurrence of the pot overflow phenomenon, and improves the user experience.

[0019] 2. As a preferred embodiment of the utility model, the edge of the air outlet is provided with convex ribs protruding toward the inside of the steam pipe or toward the inside of the air outlet to form bubble-breaking convex patterns. The convex ribs at the air outlet constitute the bubble-breaking convex patterns, and the convex ribs protrude toward the inside of the steam pipe or toward the inside of the air outlet, so that the flow area of ​​the steam pipe at the air outlet is reduced and the pressure is increased, and then when the bubbles pass through the air outlet, they will be subjected to greater pressure and can burst. At the same time, the convex ribs also block part of the air outlet. When the bubbles pass through the air outlet, they will collide with the convex ribs and be squeezed by the convex ribs, which will accelerate the rupture, thereby improving the bubble-breaking effect, and the bubbles will burst before entering the steam chamber, and the liquid in the bubbles can directly flow back downward through the steam pipe, thereby reducing the risk of overflow while ensuring the cleanliness of the steam chamber.

[0020] 3. As a preferred embodiment of the utility model, the cover body is provided with an exhaust port connected to the steam chamber, the exhaust port is staggered with the steam pipe, and the exhaust port faces the direction of the steam pipe away from the exhaust port. The exhaust port and the exhaust port are staggered, and the exhaust port faces away from the exhaust port, so that the path of the fluid from the exhaust port to the exhaust port is longer and more tortuous, which helps to further reduce the kinetic energy of the fluid and cause the bubbles to burst and the liquid to flow back.

[0021] 4. As a preferred embodiment of the utility model, the cover body is provided with an exhaust port connected to the steam chamber, the exhaust port is staggered with the steam pipe, a steam barrier is provided between the steam pipe and the exhaust port, and a bubble-breaking convex pattern is provided on the steam barrier. The fluid flowing out of the air outlet needs to bypass the bottom of the steam barrier before reaching the exhaust port, further extending the airflow path and reducing the kinetic energy of the airflow. When the fluid flows to the steam barrier, it will collide with the steam barrier. The bubble-breaking convex pattern is provided on the steam barrier, making the surface of the steam barrier more uneven, and when it collides with the bubbles, the bubbles are more likely to break, thereby further improving the bubble-breaking and overflow-prevention effect.

[0022] 5. As a preferred embodiment of the utility model, the top wall of the steam chamber has a bubble breaking area corresponding to the top of the steam pipe, and the bubble breaking convex pattern is arranged in the bubble breaking area. After the airflow and bubbles flow out from the air outlet of the steam pipe, they will naturally surge upwards and then contact the bubble breaking area on the top wall of the steam chamber, and then the collision with the bubble breaking convex pattern will further help the bubbles to break.

[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.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

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 2 , Figure 5 , Figure 6 , Fig. 9 , Fig.10 As shown, a pot cover assembly includes a cover body 1 and an inner cover 2, a steam valve 3 is arranged between the cover body 1 and the inner cover 2, a steam pipe 32 and a steam chamber 31 are arranged in the steam valve 3, the steam pipe 32 has an air inlet 321 and an air outlet 322, the air inlet 321 is connected to the cooking cavity, the air outlet 322 is connected to the steam chamber 31, and a bubble-breaking convex pattern 33 is arranged at the air outlet 322 and / or the inner wall of the steam chamber 31.

[0046] In the utility model, the gas in the cooking cavity enters the steam pipe 32 through the air inlet 321, enters the steam chamber 31 through the air outlet 322 of the steam pipe 32, and is finally discharged from the steam chamber 31. The air outlet 322 and / or the inner wall of the steam chamber 31 are provided with bubble-breaking convex patterns 33, that is, the bubble-breaking convex patterns 33 are arranged on the flow path of the fluid and protrude toward the inside of the channel. When the gas carries bubbles through the air outlet 322 and / or the bubble-breaking convex patterns 33 provided on the inner wall of the steam chamber 31, the bubble-breaking convex patterns 33 can squeeze the bubbles, thereby further facilitating the bubble to burst. At the same time, the flow area of ​​the position where the bubble-breaking convex patterns 33 are provided is reduced. When the airflow passes through, it will collide with the bubble-breaking convex patterns 33, and then the bubble bursting can also be accelerated under the action of the impact force. By setting the bubble breaking convex pattern 33, the bubbles are subjected to squeezing and impact forces when passing through, which greatly improves the bubble breaking efficiency and effect, helps the bubbles to burst before reaching the exhaust port 37 of the steam chamber 31, and then allows the liquid to flow back in the steam valve 3, greatly reducing the risk of bubbles and liquid spraying out of the exhaust port 37 of the steam valve 3, alleviating the occurrence of overflow, and improving the user experience.

[0047] It should be noted that the present invention does not limit the structure of the bubble-breaking convex pattern 33, which may be a rib 331 structure, or a convex point arranged in an array, or the bubble-breaking convex pattern 33 is an uneven structure with a certain texture. Among them, the present invention does not limit the shape of the convex structure in the bubble-breaking convex pattern 33. In one embodiment, the end of the convex structure that contacts the bubble is a pointed tip, so that the bubble can be punctured when it contacts the bubble. Of course, the convex structure can also be other shapes.

[0048] Preferably, if Figure 3 , Figure 4 As shown, the bottom wall of the steam chamber 31 is also provided with a reflux port 39 , and a reflux valve is provided at the reflux port 39 to allow the liquid in the steam chamber to flow back into the pot in time to avoid accumulation in the steam chamber 31 .

[0049] The present invention does not limit the location of the bubble-breaking convex pattern 33, which includes but is not limited to the following embodiments:

[0050] Implementation method 1: In this implementation method, Figures 1 to 4 As shown, the edge of the gas outlet 322 is provided with a convex rib 331 protruding toward the inside of the steam pipe 32 or toward the inside of the gas outlet 322 to form a bubble-breaking convex pattern 33.

[0051] The ribs 331 at the gas outlet 322 form bubble-breaking ribs 33. The ribs 331 protrude toward the inside of the steam pipe 32 or the gas outlet 322, so that the flow area of ​​the steam pipe 32 at the gas outlet 322 is reduced and the pressure is increased. When the bubbles pass through the gas outlet 322, they will be subjected to greater pressure and can break. At the same time, the ribs 331 also block part of the gas outlet 322. When the bubbles pass through the gas outlet 322, they will collide with the ribs 331 and be squeezed by the ribs 331, which will accelerate the breakage, thereby improving the bubble-breaking effect. The bubbles break before entering the steam chamber 31, and the liquid in the bubbles can directly flow back downward through the steam pipe 32, thereby reducing the risk of overflow and ensuring the cleanliness of the steam chamber 31.

[0052] Specifically, Figure 3 , Figure 4 As shown, the rib 331 can protrude toward the inside of the steam pipe 32 or toward the outside of the steam pipe 32, and form a shield for a partial area of ​​the air outlet 322. As long as the airflow and bubbles can come into contact with the rib 331 when flowing out of the air outlet 322, no limitation is made here.

[0053] Furthermore, if Figure 4 As shown, there are multiple ribs 331, which are arranged at intervals along the edge of the air outlet 322, and a gas gap 361 is formed between two adjacent ribs 331. The ribs 331 are arranged on at least one side of the edge of the air outlet 322, and preferably, as shown in FIG. Figure 4 As shown, the rib 331 surrounds the air outlet 322 .

[0054] Implementation method 2: In this implementation method, Figures 5 to 8 As shown, the cover body 1 is provided with an exhaust port 37 connected to the steam chamber 31 , the exhaust port 37 and the steam pipe 32 are arranged in a staggered manner, a steam barrier rib 36 is arranged between the steam pipe 32 and the exhaust port 37 , and the bubble-breaking convex pattern 33 is arranged on the steam barrier rib 36 .

[0055] The fluid flowing out of the air outlet 322 needs to bypass the bottom of the steam barrier rib 36 before reaching the exhaust port 37, further extending the airflow path and reducing the kinetic energy of the airflow. When the fluid flows to the steam barrier rib 36, it will collide with the steam barrier rib 36. The bubble breaking convex pattern 33 is set on the steam barrier rib 36, so that the surface of the steam barrier rib 36 is more uneven, and when it collides with the bubbles, the bubbles are more likely to burst, thereby further improving the bubble breaking and overflow prevention effect.

[0056] Specifically, Figure 6 As shown, the steam barrier rib 36 is disposed on the cover body 1 and extends downward, and the lower edge of the steam barrier rib 36 is lower than the height of the position where the gas outlet 322 is located. An air gap 361 is formed between the lower edge of the steam barrier rib 36 and the bottom wall of the steam chamber 31. After the airflow and bubbles flow out of the gas outlet 322, they are located above the air gap 361 and thus cannot flow toward the exhaust port 37. Only after contacting the steam barrier rib 36 and turning downward can they reach the air gap 361. Therefore, it is ensured that more bubbles can contact or collide with the steam barrier rib 36, thereby improving the bubble breaking effect of the steam barrier rib 36.

[0057] In one embodiment, the bubble breaking convex pattern 33 may be arranged on the wall surface of the steam barrier rib 36 facing the steam pipe 32. Since the wall surface area of ​​the steam barrier rib 36 facing the steam pipe 32 is large, more convex structures may be arranged to form a large-area bubble breaking convex pattern 33, thereby increasing the probability of bubbles contacting the bubble breaking convex pattern 33 and improving the bubble breaking effect.

[0058] For example, specifically, a plurality of convex structures arranged in an array may be provided on the wall surface of the steam barrier rib 36 to form the bubble-breaking convex pattern 33 .

[0059] In another embodiment, if Figure 6 As shown, the bubble breaking convex pattern 33 is arranged at the lower end of the steam barrier rib 36. The bubble breaking convex pattern 33 is arranged at the lower end of the steam barrier rib 36, so that the flow area of ​​the air gap 361 at the lower end of the steam barrier rib 36 is further reduced. With the arrangement of the bubble breaking convex pattern 33, the squeezing effect on the bubbles flowing thereto can be increased, thereby further improving the bubble breaking effect. Preferably, as Figure 8 As shown, the bubble-breaking convex patterns 33 are arranged at intervals along the length direction of the steam barrier ribs 36 .

[0060] Implementation method three: In this implementation method, if Figures 9 to 12 As shown, the top wall of the steam chamber 31 has a bubble breaking area 311 correspondingly located above the steam pipe 32 , and the bubble breaking convex pattern 33 is arranged in the bubble breaking area 311 .

[0061] After the airflow and bubbles flow out from the air outlet 322 of the steam pipe 32 , they will naturally surge upwards and then contact the bubble breaking area 311 on the top wall of the steam chamber 31 , and then the collision with the bubble breaking convex pattern 33 will further help the bubbles to break.

[0062] Furthermore, if Fig.10 , Fig.12 As shown, there is a steam barrier rib 36 inside the steam chamber 31, and the steam barrier rib 36 divides the steam chamber 31 into a bubble breaking chamber 312 and an exhaust chamber 313. The bubble breaking area 311 constitutes the top wall of the bubble breaking chamber 312, and the steam pipe 32 extends into the bubble breaking chamber 312. The bubble breaking chamber 312 and the exhaust chamber 313 are arranged horizontally, so that the airflow and bubbles entering the bubble breaking chamber 312 need to be turned before they can enter the exhaust chamber 313, thereby extending the path of the airflow flow to reduce kinetic energy, so that the bubbles fall under the gravity of the internal liquid and separate from the airflow. In addition, the bubble breaking convex pattern 33 contacts the bubbles in the bubble breaking chamber 312 to break the bubbles. After the bubbles burst, the liquid falls into the bubble breaking chamber 312, and then completes the reflux in the bubble breaking chamber 312, reducing the liquid accumulated in the exhaust chamber 313, ensuring that the exhaust chamber 313 is clean, and the liquid will not gather near the exhaust port 37, thereby avoiding the airflow from bringing the liquid out of the exhaust port 37 during the exhaust process to cause overflow.

[0063] Specifically, Fig.12 As shown, the bubble breaking area 311 is provided with a plurality of convex points to form a bubble breaking convex pattern 33, and the plurality of convex points are arranged in an array.

[0064] It should be noted that the above three embodiments can be implemented separately or in combination, that is, both the air outlet 322 and the inner wall of the steam chamber 31 are provided with bubble-breaking convex patterns, which is not limited here.

[0065] Preferably, if Figure 2 , Figure 4 As shown, the steam pipe 32 has a top wall to close the top of the steam pipe 32, and the air outlet 322 faces horizontally or tilted upward.

[0066] After the gas and bubbles enter the steam pipe 32, the flow direction is vertically upward, and the top wall of the steam pipe 32 closes the top of the internal channel, so that the airflow and bubbles will be blocked by the top wall and then collide with the top wall, thereby accelerating the bursting of the bubbles, causing the bubbles to burst under the action of the collision force. At the same time, the air outlet 322 faces one side, causing the airflow to turn here. The turning of the airflow also contributes to the bursting of the bubbles, thereby reducing the kinetic energy of the bubbles on the one hand, and accelerating the bursting of the bubbles by colliding with the top wall on the other hand, thereby improving the bubble breaking effect and thus improving the anti-overflow effect.

[0067] Specifically, the air outlet 322 can be opened on the side wall of the steam pipe 32, or partially opened on the side wall of the steam pipe 32 and partially opened on the top wall of the steam pipe 32. As long as the air outlet 322 can be horizontally facing one side or inclined upward, it is not limited here.

[0068] Furthermore, if Figure 2 As shown, the cover body 1 is provided with an exhaust port 37 connected to the steam chamber 31 , the exhaust port 37 and the steam pipe 32 are arranged in a staggered manner, and the air outlet 322 faces the steam pipe 32 away from the exhaust port 37 .

[0069] The gas outlet 322 and the exhaust port 37 are staggered, and the gas outlet 322 is away from the exhaust port 37, so that the path of the fluid from the gas outlet 322 to the exhaust port 37 is longer and more tortuous, which helps to further reduce the kinetic energy of the fluid and cause the bubbles to burst and the liquid to flow back.

[0070] Preferably, if Figure 2 , Figure 4 As shown, a shielding rib 38 is provided below the exhaust port 37, and the upward projection of the shielding rib 38 covers the exhaust port 37. On the one hand, the gas is turned again when being discharged through the exhaust port 37, so that the bubbles or liquid carried in the airflow are blocked and separated from the gas. On the other hand, the shielding rib 38 blocks the exhaust port 37, and the user cannot see the interior of the steam chamber 31 through the exhaust port 37 from the outside, thereby improving the aesthetics.

[0071] As a preferred embodiment of the present invention, Figure 2 As shown, the inner cover 2 is provided with an installation port, the installation port is provided with a valve seat 34 and a sealing member 35, the cover body 1 is provided with a downwardly extending mating rib 13, the mating rib 13 abuts and seals with the sealing member 35, so that the mating rib 13, the sealing member 35 and the valve seat 34 cooperate to form a steam valve 3, and the bubble breaking convex pattern 33 is provided on the valve seat 34 and / or the cover body 1.

[0072] Preferably, the inner cover 2 is detachably mounted on the cover body 1. The steam valve 3 is partially fixed to the inner cover 2 and partially located on the cover body 1. Therefore, when the inner cover 2 is removed from the cover body 1, the steam valve 3 is opened, and the user can clean the inside of the steam valve 3, which reduces the cleaning pressure of the user and helps to ensure the cleanliness of the inside of the steam valve 3. When the inner cover 2 is installed on the cover body 1, the matching rib 13 abuts against the sealing member 35, cooperates with the valve seat 34 and the sealing member 35 to form the steam chamber 31, and ensures the sealing of the steam chamber 31 to avoid air leakage.

[0073] Specifically, Figure 2 As shown, the steam pipe 32 is arranged on the valve seat 34 . After assembly, the steam pipe 32 extends into the steam chamber 31 .

[0074] In another embodiment, if Figure 5 , Figure 6 , Fig. 9 , Fig.10 As shown, the cover body 1 includes a surface cover 11 and a lining cover 12, the surface cover 11 is provided with a mating port, the steam valve 3 includes a mating portion 121 which is arranged on the lining cover 12 and protrudes upward, the mating portion 121 abuts and cooperates with the valve seat 34 and the sealing member 35 on the inner cover 2 to form a steam chamber 31, and the exhaust port 37 is arranged on the mating portion 121 and is plugged into and cooperated with the mating port.

[0075] The utility model also discloses a cooking utensil, comprising a pot body with a cooking cavity, and the pot cover assembly, wherein the air inlet 321 is connected to the cooking cavity, and at least a part of the steam valve 3 is detachably fixed to the pot cover assembly.

[0076] It should be noted that the utility model does not limit the type of cooking utensil, which can be a normal pressure cooking utensil, such as a rice cooker, or a pressure cooking utensil, such as an electric pressure cooker. The design that at least part of the steam valve 3 is detachable makes it easy for the user to remove the steam valve 3 separately for cleaning.

[0077] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0078] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0079] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
