Description

Technical Field

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

[0002] Cooking utensils typically consist of a pot and a lid, with a steam valve installed on the lid to release gas and steam from the pot during or after cooking. Some cookers also have a temperature sensor on the lid. This sensor monitors the pot's temperature to prevent it from overheating and prevents overflow. The temperature sensor detects the temperature at the top of the pot to determine whether the liquid is boiling. If the liquid is boiling, there's a risk of overflowing from the steam valve. At this point, the temperature sensor sends a signal to the control unit, which instructs the heating device to stop heating.

[0003] However, the temperature measuring element is typically located at the top center of the pot lid. A common temperature measuring element is a downwardly protruding temperature probe that extends into the pot. The steam valve is typically located off-center from the cooking appliance, meaning it's located off-center. This places the location where gas and liquid overflow from the temperature measuring probe at a considerable distance, often leading to discrepancies between the temperature measured by the temperature measuring probe and the actual amount of bubbles or liquid overflowing. Specifically, the following false detections may occur: First, the control unit activates prematurely. This means that even though the pot has reached boiling point, the bubbles and liquid inside have not yet risen or reached the lid, and the temperature measuring probe signals the control unit to stop heating. This causes the heating unit to stop prematurely, reducing heating efficiency. Second, the control unit activates laggingly. This means that after the liquid boils, bubbles and liquid quickly rise, causing overflow, but the temperature measuring probe reacts slowly, causing overflow at the steam valve before the control unit stops heating. Finally, the temperature measuring probe's inaccuracy can lead to incorrect predictions of the pot's top temperature.

[0004] Chinese patent CN114947514A discloses a rice cooker in which gas from the pot is discharged through a cylinder on the pot lid. The cylinder is also equipped with an electrostatic capacitance detector to detect the electrostatic capacitance of the fluid flowing inside the cylinder to determine whether liquid has entered the cylinder along with the gas. In this patent, the detector is located at the gas outlet position, allowing it to directly detect substances passing through the cylinder, thereby enabling the rice cooker to respond more promptly to overflowing events.

[0005] However, in the above solution, the cylinder has a uniform diameter along the direction of gas outlet and has no corners. Once the gas and bubbles mixed in the gas enter the cylinder, they can be ejected quickly with great kinetic energy and without obstruction. Although the electrostatic capacitance monitoring unit can react quickly when liquid flows in, the heating device will still retain a high level of residual heat after being turned off. This is especially true for cooking utensils that use a heating plate. The heating plate dissipates heat slowly, and a large amount of residual heat will still heat the ingredients in the pot. As a result, the liquid in the pot will continue to boil for a period of time after the heating device is turned off, during which time a small amount of bubbles and liquid will still overflow through the cylinder.

[0006] Therefore, although the existing technology is relatively sensitive to the detection of overflow, it cannot effectively prevent the occurrence of overflow, and the user experience is poor. Utility Model Content

[0007] The utility model provides a pot cover assembly and a cooking utensil, which solves the problem that liquid and bubbles flowing into the steam valve are easily overflowed, based on solving the problem that the detection part is far away from the steam valve and there is an error in the time between detection and overflow.

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

[0009] A pot lid assembly includes a lid body, an inner lid, and a steam valve arranged on the lid body. The lid body and the inner lid cooperate to form a steam channel. The pot lid assembly also includes an anti-overflow detection component, which at least partially surrounds the steam channel. A docking channel is provided inside the steam valve. The flow area of the docking channel is smaller than the flow area of the steam channel, and the docking channel partially extends into the steam channel to be connected with the steam channel.

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

[0011] The anti-overflow detection component includes a connecting wall and a capacitance detection part. The connecting wall surrounds the outer periphery of at least part of the steam channel. The capacitance detection part is fixed to the connecting wall. The capacitance value of the capacitance detection part can change according to the change of the medium amount in the steam channel.

[0012] The distance between the lower edge of the docking channel and the lower edge of the capacitance detection portion is not less than 8 mm.

[0013] The steam channel has a first side facing the center of the pot cover assembly and a second side facing away from the center of the pot cover assembly, and the anti-overflow detection component is at least located on the first side.

[0014] The anti-overflow detection part surrounds a partial area of the steam channel. The steam channel has a detection area corresponding to the anti-overflow detection part along the circumference, and an air guide area staggered with the anti-overflow detection part. The docking channel has an air inlet and an air outlet, and the air inlet is set corresponding to the detection area.

[0015] An air guide column is provided inside the steam valve, the docking channel is located inside the air guide column, the air inlet is opened at the bottom end of the air guide column, the air guide column has a top wall to close the top of the docking channel, and the air outlet is opened horizontally on one side of the air guide column.

[0016] An exhaust cavity communicated with the air outlet is provided inside the steam valve. The exhaust cavity has an exhaust port. The exhaust port and the air outlet are arranged on two sides of the exhaust cavity relatively, and the air outlet is arranged away from the exhaust port.

[0017] The docking channel has an air inlet, which is located on one side of the bottom of the steam valve. A downwardly protruding shielding rib is provided on the other side of the bottom of the steam valve opposite to the air inlet, and the shielding rib extends into the steam channel.

[0018] The lid body includes a surface cover and a lining cover, the lining cover is provided with a first mating rib protruding upward, and the surface cover is provided with a second mating rib protruding downward. The pot cover assembly also includes a sealing member, the first mating rib and the second mating rib clamp and fix the sealing member, and the sealing member has a sealing lip, which abuts against the inner cover to form a steam channel.

[0019] The utility model also discloses a cooking utensil, comprising a pot body and the pot cover assembly. The inner cover cooperates with the pot body to form a cooking cavity, and the steam channel is communicated with the cooking cavity.

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

[0021] 1. In the present invention, the anti-overflow detection component at least partially surrounds the outer circumference of the steam channel so as to be able to detect the temperature and / or medium in the steam channel. When liquid or bubbles enter the steam channel, the anti-overflow detection component can respond in a timely manner and then send a signal to the control unit to shut down the heating device in time when the liquid enters the steam channel, thereby improving the detection sensitivity and accuracy of the anti-overflow detection component and greatly reducing the detection error.

[0022] In addition, a docking channel is also provided inside the steam valve, and part of the docking channel extends into the steam channel, that is, the flow area of the docking channel is smaller than the flow area of the steam channel. On the one hand, the channel has a variable diameter structure on the path of gas and liquid discharged from the steam channel. When bubbles in the steam channel enter the docking channel, the flow area suddenly decreases, causing the pressure in the channel to increase, which in turn helps the bubbles to burst, causing the liquid in the bubbles to flow back downward under the action of gravity instead of directly overflowing. On the other hand, because the docking channel extends into the steam channel, the channel wall of the docking channel can act as a barrier to the fluid in the steam channel, causing the bubbles in the steam channel to collide with the channel wall of the docking channel and accelerate their rupture, further reducing the risk of direct bubble overflow. In this way, not only can the steam channel be detected for overflow more accurately and timely, but also after the bubbles enter the steam valve, they can also burst in the steam valve. Therefore, even if the residual heat in the pot causes the liquid to remain in a short boiling state, the occurrence of overflow can be reduced.

[0023] 2. As a preferred embodiment of the present invention, the anti-overflow detection component includes a connecting wall and a capacitance detection part. The connecting wall surrounds the periphery of at least part of the steam channel. The capacitance detection part is fixed to the connecting wall. The capacitance value of the capacitance detection part can change according to the change of the amount of medium in the steam channel. Specifically, the capacitance monitoring part has multiple probe points, and there is an inductive capacitance between the probe points. When only gas passes through the steam channel, the inductive capacitance value between the probe points is a preset capacitance value. When bubbles appear in the steam channel, the inductive capacitance between the probe points changes, which transmits and converts the signal, and then converts the capacitance signal into a control signal of the control program, thereby achieving the function of controlling the intelligent device. Compared with detecting temperature, using capacitance to detect the medium in the steam channel is not only more direct, but also greatly improves the sensitivity and accuracy of the reaction. At the same time, the arrangement of the capacitance detection part is also more space-saving.

[0024] 3. As a preferred embodiment of the present invention, the anti-overflow detection member surrounds a portion of the steam channel. The steam channel has a detection area corresponding to the anti-overflow detection member along the circumference, and an air guide area offset from the anti-overflow detection member. The docking channel has an air inlet and an air outlet, and the air inlet is set corresponding to the detection area. The air inlet is located in the detection area to facilitate timely determination of bubbles. Preferably, the steam valve is provided with a reflux port and a reflux valve at a position corresponding to the air guide area so that the liquid in the steam valve can reflux. At the same time, the liquid refluxed downward will not affect the detection of the anti-overflow detection member, thereby ensuring detection accuracy.

[0025] 4. As a preferred embodiment of the present invention, an air guide column is provided inside the steam valve, the docking channel is located inside the air guide column, the air inlet is opened at the bottom end of the air guide column, the air guide column has a top wall to close the top of the docking channel, and the air outlet is horizontally opened on one side of the air guide column. The air guide column forms a docking channel inside the steam valve. After the gas and bubbles enter the docking channel, the flow direction is vertically upward, and the top wall of the air guide column closes the top of the docking 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 is oriented horizontally, causing the airflow to turn here. The turning of the airflow also helps to burst 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.

[0026] 5. As a preferred embodiment of the present invention, an exhaust cavity connected to the gas outlet is provided inside the steam valve, and the exhaust cavity has an exhaust port. The exhaust port and the gas outlet are arranged on opposite sides of the exhaust cavity, and the gas outlet is arranged away from the exhaust port. The gas outlet and the gas outlet are located on opposite sides of the steam valve, and the gas outlet is away from the exhaust port, so that the path of the fluid from the gas outlet to the exhaust port is longer and more tortuous, which helps to further reduce the kinetic energy of the fluid, causing the bubbles to burst and the liquid to flow back. The gas outlet is facing the side wall of one side of the exhaust cavity, so that after the fluid flows out of the gas outlet, it will collide with the side wall of the exhaust cavity, thereby causing the bubbles to burst.

[0039] 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.

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.

[0044] like Figure 1 、 Figure 2 、 Figure 3 As shown, a pot cover assembly includes a cover body 1, an inner cover 2, and a steam valve 4 arranged on the cover body 1. The cover body 1 and the inner cover 2 cooperate to form a steam channel 13. The pot cover assembly also includes an anti-overflow detection component 3. The anti-overflow detection component 3 at least partially surrounds the steam channel 13. A docking channel 41 is provided inside the steam valve 4. The flow area of the docking channel 41 is smaller than the flow area of the steam channel 13, and the docking channel 41 partially extends into the steam channel 13 to communicate with the steam channel 13.

[0045] In the present invention, the anti-overflow detection component 3 at least partially surrounds the outer periphery of the steam channel 13 so as to be able to detect the temperature and / or medium in the steam channel 13. When liquid or bubbles enter the steam channel 13, the anti-overflow detection component 3 can respond in a timely manner and then send a signal to the control unit so that the heating device is shut down in time when the liquid enters the steam channel 13, thereby improving the detection sensitivity and accuracy of the anti-overflow detection component 3 and greatly reducing the detection error.

[0046] In addition, the steam valve 4 is provided with a docking channel 41. Part of the docking channel 41 extends into the steam channel 13, that is, the flow area of the docking channel 41 is smaller than the flow area of the steam channel 13. On the one hand, the channel has a variable diameter structure on the path of gas and liquid discharged from the steam channel 13. When bubbles in the steam channel 13 enter the docking channel 41, the flow area suddenly decreases, causing the pressure in the channel to increase, which in turn helps the bubbles to burst, causing the liquid in the bubbles to flow back downward under the action of gravity, rather than directly overflowing. On the other hand, because the docking channel 41 extends into the steam channel 13, the channel wall of the docking channel 41 can act as a barrier to the fluid in the steam channel 13, causing the bubbles in the steam channel 13 to collide with the channel wall of the docking channel 41 and accelerate their bursting, further reducing the risk of direct bubble overflow. This not only allows for more accurate and timely overflow detection at the steam channel 13, but also allows bubbles to burst inside the steam valve 4 after entering the steam valve 4. Therefore, even if the residual heat in the pot causes the liquid to remain in a short boiling state, the occurrence of overflow can be reduced.

[0047] It should be noted that the present invention does not limit the type of overflow detection element 3. In one embodiment, the overflow detection element 3 includes a temperature measuring element to detect the temperature in the steam channel 13. The temperature reflects the boiling state of the liquid in the pot and further determines the medium in the steam channel 13. For example, when the temperature measuring element measures that the temperature in the steam channel 13 reaches the boiling temperature, it sends a signal to the control unit, which shuts down the heating device.

[0048] In a preferred embodiment, Figure 3 As shown, the overflow detection part 3 includes a connecting wall 121 and a capacitance detection part 31. The connecting wall 121 surrounds the outer periphery of at least part of the steam channel 13. The capacitance detection part 31 is fixed to the connecting wall 121. The capacitance value of the capacitance detection part 31 can change according to the change of the amount of medium in the steam channel 13. Specifically, the capacitance monitoring part has multiple detection points, and there is an inductive capacitance between the detection points. When only gas passes through the steam channel 13, the inductive capacitance value between the detection points is a preset capacitance value. When bubbles appear in the steam channel 13, the inductive capacitance between the detection points changes, and the capacitance value becomes a preset threshold. At this time, the capacitance detection part 31 will transmit and convert the signal, and then convert the capacitance signal into a control signal of the control program, thereby achieving the function of controlling the smart device. Compared with detecting temperature, using capacitance to detect the medium in the steam channel 13 is not only more direct, but also greatly improves the sensitivity and accuracy of the reaction. At the same time, the arrangement of the capacitance detection part 31 is also more space-saving.

[0049] Specifically, such as Figure 3 、 Figure 4As shown, the cover body 1 includes a surface cover 11 and a lining cover 12. The lining cover 12 has a port 122 corresponding to the steam port 21 of the inner cover 2. As a preferred embodiment of this embodiment, Figure 4 As shown, the connecting wall 121 is a rib extending upwardly and disposed on the liner 12. In another embodiment, the connecting wall 121 is a structure independent of the liner 12, and its lower end can abut against the liner 12 to surround the outer periphery of a portion of the steam port 21 of the inner cover 2.

[0050] Preferably, the capacitance detection portion 31 is fixed to the connection wall 121 by gluing.

[0051] Furthermore, if Figure 3 As shown, the distance H between the lower edge of the docking channel 41 and the lower edge of the capacitor detection part 31 is not less than 8 mm. On the one hand, it enables most areas of the capacitor detection part 31 to detect the medium inside the steam channel 13 only through the connecting wall 121, avoiding the channel wall of the docking channel 41 from affecting the detection of the capacitor detection part 31. On the other hand, when the bubbles enter the detection range of the capacitor detection part 31, they still have a certain distance from the docking channel 41 above, thereby preventing the bubbles from directly flowing into the docking channel 41, providing time for the capacitor detection part 31 to send a signal and for the control unit to react, thereby reducing the occurrence of overflow.

[0052] As a preferred embodiment of the present invention, Figure 3 、 Figure 4 As shown, the steam channel 13 has a first side facing the center of the pot cover assembly and a second side facing away from the center of the pot cover assembly, and the anti-overflow detection member 3 is at least located on the first side.

[0053] During cooking, the temperature at the center of the cooking cavity is higher than at the edges, so the liquid in the center boils earlier and more intensely. Positioning the overflow detector 3 on the side of the steam passage 13 near the center of the lid assembly allows for more sensitive and timely detection and assessment of the temperature and the medium within the steam passage 13, enabling rapid adjustments to the control program to prevent overflow.

[0054] Specifically, such as Figure 4 As shown, the lining cover 12 is provided with a through opening 122, and a connecting wall 121 is provided on the side of the through opening 122 facing the center of the pot cover assembly, and the overflow prevention detection member 3 is provided on the connecting wall 121. Of course, the connecting wall 121 can also completely surround the through opening 122, and the overflow prevention detection member 3 can also surround the through opening 122, that is, surround the steam channel 13.

[0055] Preferably, if Figure 3As shown, the anti-overflow detection component 3 surrounds a partial area of the steam channel 13, and the steam channel 13 has a detection area corresponding to the anti-overflow detection component 3 along the circumferential direction, and an air guide area staggered with the anti-overflow detection component 3, and the docking channel 41 has an air inlet 411 and an air outlet 412, and the air inlet 411 is set corresponding to the detection area.

[0056] The air inlet 411 is located in the detection area, which is convenient for timely determination of bubbles. Figure 3 As shown, the steam valve 4 has a bottom wall, and the docking channel 41 is located on the side of the bottom wall close to the anti-overflow detection component 3. The bottom wall can block the gas and bubbles in the steam channel 13, so that the fluid can only enter the steam valve 4 through the docking channel 41.

[0057] Preferably, if Figure 3 、 Figure 5 As shown, the bottom wall is provided with a reflux port 46 and a reflux valve at a position corresponding to the air guide area so that the liquid in the steam valve 4 can reflux. At the same time, the liquid refluxed downward will not affect the detection of the anti-overflow detection element 3, thereby ensuring the detection accuracy.

[0058] Preferably, the steam port 21 on the inner cover 2 and the air inlet 411 of the docking channel 41 are staggered so that the fluid path from the steam port 21 to the air inlet 411 is longer and more tortuous, which helps the bubbles to burst during movement and improves the anti-overflow effect.

[0059] Furthermore, if Figure 3 As shown, an air guide column 45 is provided inside the steam valve 4, the docking channel 41 is located inside the air guide column 45, the air inlet 411 is opened at the bottom end of the air guide column 45, the air guide column 45 has a top wall to close the top of the docking channel 41, and the air outlet 412 is horizontally opened on one side of the air guide column 45.

[0060] The air guide column 45 forms a docking channel 41 inside the steam valve 4. After the gas and bubbles enter the docking channel 41, the flow direction is vertically upward, and the top wall of the air guide column 45 closes the top of the docking channel 41, 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 412 is facing the horizontal direction, causing the airflow to turn here. The turning of the airflow also helps to burst 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, improving the bubble breaking effect, and thus improving the anti-overflow effect.

[0061] Specifically, the air outlet 412 can be opened on the side wall of the air guide column 45, or partially opened on the side wall of the air guide column 45 and partially opened on the top wall of the air guide column 45. As long as the air outlet 412 can be horizontally facing one side or tilted upward, there is no limitation here.

[0062] Furthermore, if Figure 3 As shown, the steam valve 4 is provided with an exhaust cavity 43 in communication with the air outlet 412 . The exhaust cavity 43 has an exhaust port 42 . The exhaust port 42 and the air outlet 412 are arranged on opposite sides of the exhaust cavity 43 , and the air outlet 412 is arranged away from the exhaust port 42 .

[0063] The gas outlet 412 and the exhaust port 42 are located on opposite sides of the steam valve 4, with the gas outlet 412 facing away from the exhaust port 42. This makes the fluid's path from the gas outlet 412 to the exhaust port 42 longer and more tortuous, further reducing the fluid's kinetic energy, causing bubbles to burst and the liquid to flow back. Furthermore, the gas outlet 412 faces the sidewall of the exhaust chamber 43, so that after the fluid flows out of the gas outlet 412, it will collide with the sidewall of the exhaust chamber 43, thereby bursting the bubbles.

[0064] Preferably, if Figure 3 As shown, a steam barrier rib 44 is provided between the air outlet 412 and the exhaust port 42. The lower edge of the steam barrier rib 44 is lower than the air outlet 412, so that the fluid flowing out of the steam port 21 needs to bypass the bottom of the steam barrier rib 44 before reaching the exhaust port 42, further extending the airflow path and reducing the kinetic energy of the airflow. The collision of bubbles with the steam barrier rib 44 can also accelerate their rupture, thereby further improving the bubble breaking and overflow prevention effect.

[0065] Preferably, if Figure 3 、 Figure 5 As shown, the docking channel 41 has an air inlet 411, which is located on one side of the bottom of the steam valve 4. A downwardly protruding shielding rib 47 is provided on the other side of the bottom of the steam valve 4 opposite to the air inlet 411, and the shielding rib 47 extends into the steam channel 13.

[0066] On the one hand, the shielding rib 47 serves to align the steam valve 4 with the steam passage 13. The shielding rib 47 cooperates with the inner wall of the steam passage 13 to guide and position the steam valve 4 during installation, ensuring accurate alignment between the steam valve 4 and the steam passage 13, reducing assembly difficulty, improving sealing, and preventing air leakage. On the other hand, it blocks gas and bubbles that enter the steam passage 13 and flow toward this side, converging the fluid and guiding it toward the location of the docking passage 41.

[0067] As a preferred embodiment, Figure 3 As shown, the lid body 1 includes a surface cover 11 and a lining cover 12, the lining cover 12 is provided with a first mating rib 15 protruding upward, and the surface cover 11 is provided with a second mating rib 14 protruding downward. The pot cover assembly also includes a seal 5, the first mating rib 15 and the second mating rib 14 clamp and fix the seal 5, and the seal 5 has a sealing lip 51, which abuts against the inner cover 2 to form a steam channel 13.

[0068] After the lid assembly is assembled, the first mating rib 15 and the second mating rib 14 together support and fix the seal 5, thereby fixing the seal 5 and reducing the difficulty of installing the seal 5. Preferably, the inner cover 2 is detachably mounted on the lid body 1, so that the steam channel 13 can be opened and the user can clean the inside of the steam channel 13. Specifically, Figure 3 As shown, the seal 5 has a laterally outwardly projecting mating protrusion, with a first mating rib 15 and a second mating rib 14 located on the upper and lower sides of the mating protrusion, respectively, clamping the mating protrusion. The sealing lip 51 of the seal 5 abuts the inner cover 2 and surrounds the outer periphery of the steam port 21 of the inner cover 2, thereby connecting the steam port 21 with the steam passage 13.

[0069] Furthermore, if Figure 1 、 Figure 3 As shown, the upper surface of the cover 11 is provided with a downwardly recessed mounting groove, into which the steam valve 4 is removably mounted by means of an interference fit, threaded connection, or the like, allowing the user to remove the steam valve 4 to clean its interior and the interior of the steam passage 13. Specifically, the seal 5 has a sealing rib protruding toward the interior of the steam passage 13. After the steam valve 4 is installed, the sealing rib abuts against the outer circumference of the steam valve 4 for a sealed seal.

[0070] The utility model also discloses a cooking utensil, comprising a pot body and the pot cover assembly. The inner cover 2 cooperates with the pot body to form a cooking cavity, and the steam channel 13 is connected to the cooking cavity.

[0071] It should be noted that the present invention does not limit the type of cooking appliance. It can be a normal pressure cooking appliance, such as an electric rice cooker, or a pressure cooking appliance, such as an electric pressure cooker.

[0072] Anything not described in this utility model can be achieved by adopting or drawing on existing technologies.

[0073] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.
