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 appliance. Background Art

[0002] The pot cover of a cooking appliance is usually provided with an exhaust valve for discharging the gas in the pot. However, during the exhaust process, due to the boiling in the pot or the large impact force of the air flow, certain bubbles or liquids will be carried out through the exhaust valve, resulting in the phenomenon of overflowing the pot, leaving the liquid and food soup on the surface of the pot cover, causing pollution and increasing the cleaning burden of users.

[0003] In order to alleviate the occurrence of the overflowing pot phenomenon, cooking appliances usually also have an anti-overflow structure. The anti-overflow function of common cooking appliances is realized by a temperature measuring probe arranged on the pot cover. The temperature inside the pot is detected in real time by the temperature measuring probe, and then it is judged whether the pot is boiling through program control. If it is boiling, the probability of overflowing the pot will increase greatly. At this time, the heating device can be controlled to stop heating or reduce the power. If it is not boiling, the heating device is controlled to continue heating.

[0004] However, from the time when the temperature measuring probe collects the temperature data inside the pot to the time when the control unit controls the heating device, complex program writing by electronic control personnel is required in the middle process. In the actual operation process, data deviation is often caused by differences in the sensitivity of the temperature measuring probe and other factors, and affected by factors such as the differences in the experience and technical capabilities of electronic control personnel. When the cooking appliance is working, the temperature control is often inaccurate, and then misjudgment occurs in the determination of the overflowing pot phenomenon of the product.

[0005] In addition, Chinese Patent CN209285050U discloses an anti-overflow cooking appliance. Its pot cover includes a face cover assembly and a detachable inner cover located below the face cover assembly. A temperature measuring probe is provided on the pot cover, and a temperature measuring hole is provided on the detachable inner cover. One end of the temperature measuring probe passes through the temperature measuring hole and extends into the cooking cavity to form a first anti-overflow detection electrode. The detachable inner cover is a conductive part to form a second anti-overflow detection electrode. The temperature measuring probe and the detachable inner cover are respectively electrically connected to the control board. When the pot is boiling, the liquid and bubbles surge up to connect the detachable inner cover and the first anti-overflow detection electrode, so as to judge the boiling situation inside the pot.

[0006] However, in the above solution, the detachable inner lid as a whole is used as a conductive part to form the second anti-overflow detection electrode. On the one hand, the volume of the detachable inner lid is relatively large, and the distances between its various regions and the first anti-overflow detection electrode also vary greatly. When boiling starts or local boiling occurs in the pot, it is often difficult to connect the two electrodes. Only when the pot is boiling completely can the two electrodes be effectively connected. Therefore, there is also a certain lag in determining the boiling situation in the pot, and the reaction is relatively slow. On the other hand, the detachable inner lid needs to be electrically connected to the control board, and the detachable inner lid is a detachable structure. Therefore, frequent installation and disassembly are bound to affect the stability of its electrical connection with the control board, thereby affecting the reliability of anti-overflow detection. Utility Model Content

[0007] The utility model provides a pot lid assembly and a cooking appliance to solve the problems that the existing anti-overflow structure of the pot lid has a large detection error for the boiling situation in the pot, resulting in the control unit being unable to control the heating device to react in time, and designing the inner lid as a whole as an electrode, causing inconvenience in use.

[0008] The technical solution adopted by the utility model is as follows:

[0009] A pot lid assembly includes a lid body and an inner lid. The lid body is provided with a detection assembly, and the inner lid is provided with a through hole. The detection assembly passes through the through hole and extends below the inner lid; the detection assembly includes a temperature measuring probe and an anti-overflow detection part fixed to the temperature measuring probe. The anti-overflow detection part includes a first electrode part and a second electrode part with an electrode opposite to that of the first electrode part. The second electrode part is sleeved outside the first electrode part, and there is a first insulating layer between the first electrode part and the second electrode part.

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

[0011] The first electrode part is sleeved on the outer peripheral side of the temperature measuring probe, the second electrode part is sleeved on the outer peripheral side of the first electrode part, and the first insulating layer is located between the first electrode part and the second electrode part.

[0012] The lower edge of the first electrode part is higher than the lower edge of the temperature measuring probe, the lower edge of the first insulating layer is higher than the lower edge of the first electrode part, and the lower edge of the second electrode part is higher than the lower edge of the insulating layer.

[0013] The first insulating layer has a wrapped section wrapped by the second electrode part and an exposed section located outside the second electrode part. The exposed section is located below the wrapped section, and a diversion inclined surface is arranged on the outer wall of the exposed section.

[0014] A second insulating layer is further arranged between the first electrode part and the temperature measuring probe; or, there is an insulating gap between the first electrode part and the temperature measuring probe.

[0015] A mounting portion is provided on the top of the detection component, a mounting position is provided on the side of the cover body away from the inner cover, the cover body is provided with a through hole for the detection component to pass through, and a sealing ring is also provided between the detection component and the cover body to seal the gap between the through hole and the detection component.

[0016] The sealing ring is arranged between the outer peripheral side of the detection component and the inner wall of the through hole; or, the detection component has a fixed flange located above the cover body, and the sealing ring is arranged between the fixed flange and the cover body.

[0017] The pot cover assembly also includes a sealing member fixed on the edge of the opening, the sealing member surrounds the opening, and the sealing member has a sealing lip extending upward, and the sealing lip abuts against the cover body for sealing.

[0018] The detection component and the inner cover are arranged with a center offset.

[0019] The utility model also discloses a cooking utensil, comprising a pot body with a cooking cavity and the above-mentioned pot cover assembly; a temperature measuring probe extends into the cooking cavity through a port, and at least a part of the first electrode part and the second electrode part extend into 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 utility model, the temperature probe and the overflow prevention detection part are integrated together, so that the detection component can realize the integration of temperature measurement and overflow prevention detection functions at the same time. The detection component extends into the pot, and the temperature probe is used to detect the temperature in the pot in real time. When the pot is not boiling, the first electrode part and the second electrode part of the overflow prevention detection part are isolated from each other by the first insulating layer between the two. When the pot boils, bubbles and liquid rise to the inner cover and connect the first electrode part and the second electrode part electrically. At this time, the detection component sends a signal to the control unit, indicating that the pot has reached a boiling state. Since the second electrode part is sleeved on the first electrode part, the distance between the first electrode part and the second electrode part is greatly shortened. Therefore, once boiling occurs in the pot, the liquid and bubbles can more easily conduct the two, thereby improving the sensitivity of the overflow prevention detection part, which helps the control unit to respond in time. At the same time, the nested assembly method of the first electrode part and the second electrode part also reduces the volume of the two after assembly, thereby reducing the space occupied by the overflow prevention detection part, which helps to optimize the structural layout of the pot cover assembly.

[0022] In addition, the first electrode portion and the second electrode portion are both arranged on the temperature measuring probe, so the detection component can be assembled on the pot cover assembly as an independent component, and the various parts of the anti-overflow detection component will not be separated when the inner cover is removed, thereby always maintaining a stable electrical connection and improving reliability.

[0023] 2. As a preferred embodiment of the present utility model, the first electrode part is sleeved on the outer peripheral side of the temperature measuring probe, the second electrode part is sleeved on the outer peripheral side of the first electrode part, and the first insulating layer is located between the first electrode part and the second electrode part. The temperature measuring probe, the first electrode part and the second electrode part are sleeved from the inside to the outside, and the first insulating layer is sleeved on the outside of the first electrode part, so that the overall detection component is in a columnar structure, similar to the shape of the temperature measuring probe, and the volume does not change much compared with the temperature measuring probe. Furthermore, it helps to further realize the miniaturized design of the temperature measuring component, and there is no need to separately assemble each component. The anti-overflow detection component can be first fixed to the temperature measuring probe and then assembled to the cover body together, thereby reducing the assembly difficulty and facilitating the connection of the circuit at the same time. The wiring position is more concentrated, which helps to centralize the wiring.

[0024] 3. As a preferred embodiment of the present utility model, the lower edge of the first electrode part is higher than the lower edge of the temperature measuring probe, the lower edge of the first insulating layer is higher than the lower edge of the first electrode part, and the lower edge of the second electrode part is higher than the lower edge of the insulating layer. The lower edge of the first electrode part being higher than the lower edge of the temperature measuring probe exposes the lower end of the temperature measuring probe, thus facilitating the perception of the temperature inside the pot. The lower end of the first insulating part being higher than the lower end of the first electrode part exposes the lower end of the first electrode part, and the upper part is wrapped by the first insulating layer, and conduction is achieved through the exposed part and the second electrode part on the outside. In this way, it not only ensures that the first insulating layer effectively isolates the two electrodes when the liquid in the pot is not boiling, but also ensures that the first electrode part has a large enough area for conduction with the second electrode part. Furthermore, when the liquid in the pot boils, the two electrodes can conduct stably, generating a continuous and stable electrical signal.

[0025] 4. As a preferred embodiment of the present utility model, the pot cover assembly further includes a seal fixed to the edge of the through-opening. The seal surrounds the through-opening and has a sealing lip extending upward, and the sealing lip abuts against the cover body for sealing. The sealing lip abuts against the cover body for sealing, so that the cover body, the seal and the inner cover cooperate to enclose a detection channel. Gas, bubbles, liquid, etc. inside the pot can enter the detection channel through the through-opening and contact the temperature measuring probe and the anti-overflow detection component. However, since the seal abuts against the cover body and the inner cover for sealing respectively, gas and the like cannot enter the inside of the pot cover assembly, thereby ensuring the cleanliness inside the pot cover assembly. At the same time, since the seal is fixed to the inner cover, it can be removed together with the inner cover, which is convenient for the user to clean the seal.

[0026] 5. As a preferred embodiment of the present utility model, the detection component is arranged offset from the center of the inner lid. Usually, the exhaust valve is arranged offset from the center of the pot lid assembly. During the cooking process, the heat of the heating device is more concentrated in the center of the cooking space. Therefore, the food at the center reaches boiling relatively earlier and boils more violently. However, at the initial stage of boiling, although the liquid in the pot has boiled, there will be no liquid or bubbles reaching the exhaust valve, and there is no risk of overflow. Therefore, by arranging the detection component eccentrically on the inner lid, the anti-overflow detection component can be triggered only when the liquid at the position where the detection component is located boils, and at this time, the control unit reacts. In this way, it is possible to avoid the premature shutdown of the heating device, resulting in a reduction in heating efficiency, ensure the heating efficiency on the basis of reducing the risk of overflow, and improve the user experience.

[0042] In the following description, many specific details are set forth in order to fully understand the present invention.

In the description of this specification, the description with reference to terms such as "embodiment", "example", "an embodiment", "example" or "specific example" etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model.

Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0046] As Figure 1 , Figure 3 , Figure 4 shown, a pot lid assembly includes a lid body 1 and an inner lid 2. The lid body 1 is provided with a detection assembly 3. The inner lid 2 is provided with a through opening 21. The detection assembly 3 passes through the through opening 21 and extends to the lower side of the inner lid 2. The detection assembly 3 includes a temperature measurement probe 31 and an anti-overflow detection member 32 fixed to the temperature measurement probe 31. The anti-overflow detection member 32 includes a first electrode portion 321 and a second electrode portion 322 with an electrode opposite to that of the first electrode portion 321. The second electrode portion 322 is sleeved on the outer side of the first electrode portion 321. A first insulating layer 33 is provided between the first electrode portion 321 and the second electrode portion 322.

[0047] In the present utility model, the temperature measurement probe 31 and the anti-overflow detection member 32 are integrated together, enabling the detection assembly 3 to simultaneously realize the integration of the functions of temperature measurement and anti-overflow detection. The detection assembly 3 extends into the pot. The temperature measurement probe 31 is used to detect the temperature in the pot in real time. In the state where the liquid in the pot has not boiled, the first electrode portion 321 and the second electrode portion 322 of the anti-overflow detection member 32 are insulated from each other through the first insulating layer 33 therebetween. When the liquid in the pot boils, bubbles and liquid surge to the inner lid 2 and electrically connect the first electrode portion 321 and the second electrode portion 322. At this time, the detection assembly 3 sends a signal to the control unit, indicating that the liquid in the pot has reached the boiling state. Since the second electrode portion 322 is sleeved on the first electrode portion 321, the distance between the first electrode portion 321 and the second electrode portion 322 is greatly shortened. Therefore, once boiling occurs in the pot, the liquid and bubbles can more easily conduct the two, thereby improving the sensitivity of the reaction of the anti-overflow detection member 32 and helping the control unit to make a timely response. At the same time, the nested assembly method of the first electrode portion 321 and the second electrode portion 322 also reduces the volume after their assembly, thereby reducing the space occupied by the anti-overflow detection member 32 and helping to optimize the structural layout of the pot lid assembly.

[0048] In addition, both the first electrode portion 321 and the second electrode portion 322 are provided on the temperature measuring probe 31. Therefore, the detection component 3 can be assembled as an independent component to the pot lid assembly, and each part of the anti-overflow detection member 32 will not be separated with the disassembly of the inner lid 2, thus always maintaining a stable electrical connection and improving reliability.

[0049] Specifically, the present utility model does not limit the polarities of the first electrode portion 321 and the second electrode portion 322. For example, the first electrode portion 321 can be the cathode, and in this case, the second electrode portion 322 is the anode. Of course, the polarities of the two can also be opposite, as long as the polarities of the two are different.

[0050] Preferably, in the present utility model, the sensitivities of the first electrode portion 321 and the second electrode portion 322 can be adjusted to facilitate controlling their conduction at a specific stage. For example, in the initial stage of heating, although the liquid in the pot has not boiled, the moist air in the pot surges upward, and there is also a possibility of causing the first electrode portion 321 and the second electrode portion 322 to conduct. Therefore, their sensitivities should be set so that they do not conduct and emit signals in this case. Only when the liquid in the pot boils, a large number of bubbles surge here, or the liquid submerges the first electrode portion 321 and the second electrode portion 322, will they conduct normally and emit signals.

[0051] It should be noted that the present utility model does not limit the relative positions of the anti-overflow detection member 32 and the temperature measuring probe 31. In one embodiment, the anti-overflow detection member 32 and the temperature measuring probe 31 are arranged in a staggered manner so that they can be independently processed to avoid interference and influence on each other during operation.

[0052] And as a preferred implementation manner of the present utility model, as Figure 3 、 Figure 4 shown, the first electrode portion 321 is sleeved on the outer peripheral side of the temperature measuring probe 31, the second electrode portion 322 is sleeved on the outer peripheral side of the first electrode portion 321, and the first insulating layer 33 is located between the first electrode portion 321 and the second electrode portion 322.

[0053] The temperature measuring probe 31, the first electrode portion 321, and the second electrode portion 322 are sleeved from the inside to the outside, and the first insulating layer 33 is sleeved on the outside of the first electrode portion 321, so that the overall detection component 3 is in a columnar structure, similar to the shape of the temperature measuring probe 31, and the volume does not change much compared with the temperature measuring probe 31. Furthermore, it helps to further realize the miniaturized design of the temperature measuring component, and there is no need to separately assemble each component. The anti-overflow detection member 32 can be fixed to the temperature measuring probe 31 first and then assembled to the lid body 1 together, thereby reducing the assembly difficulty while also facilitating the connection of the circuit, making the wiring position more concentrated and contributing to centralized wiring.

[0054] Furthermore, as Figure 3 、 Figure 4As shown, the lower edge of the first electrode portion 321 is higher than the lower edge of the temperature measuring probe 31, the lower edge of the first insulating layer 33 is higher than the lower edge of the first electrode portion 321, and the lower edge of the second electrode portion 322 is higher than the lower edge of the insulating layer. Further, as Figure 3 、 Figure 4 shown, the first insulating layer 33 has a wrapped section wrapped by the second electrode portion 322 and an exposed section located outside the second electrode portion 322, and the exposed section is located below the wrapped section.

[0055] The lower edge of the first electrode portion 321 is higher than the lower edge of the temperature measuring probe 31, so that the lower end of the temperature measuring probe 31 is exposed, facilitating the perception of the temperature inside the pot. The lower end of the first insulating portion is higher than the lower end of the first electrode portion 321, so that the lower end of the first electrode portion 321 is exposed and is wrapped by the first insulating layer 33 above, and conduction is achieved through the exposed part and the second electrode portion 322 outside. In this way, it not only ensures that the first insulating layer 33 effectively isolates the two electrodes when the liquid in the pot is not boiling, but also ensures that the first electrode portion 321 has a large enough area for conduction with the second electrode portion 322. Furthermore, when the liquid in the pot is boiling, the two electrodes can conduct stably, generating a continuous and stable electrical signal.

[0056] Furthermore, as Figure 3 shown, a diversion inclined surface 331 is provided on the outer wall of the exposed section.

[0057] Since the detection assembly 3 is a columnar structure as a whole, and the upward direction of the gas, liquid, etc. in the pot is from bottom to top, the bubbles and liquid will first contact the lower end of the detection assembly 3, that is, the temperature measuring probe 31, and gradually rise along the outer surface of the detection assembly 3. The setting of the diversion inclined surface 331 improves the guiding effect on the bubbles and liquid, enabling the liquid to quickly rise along the diversion inclined surface 331 to the second electrode portion 322, so as to more quickly and timely complete the conduction between the first electrode portion 321 and the second electrode portion 322, greatly improving the reaction sensitivity of the anti-overflow detection member 32.

[0058] It should be noted that in order to prevent a conductive path from being formed between the first electrode portion 321 and the temperature measuring probe 31, the first electrode portion 321 and the temperature measuring probe 31 need to be insulated and blocked. However, the insulation method between the two is not limited in this embodiment. In one embodiment, there is an insulating gap between the first electrode portion 321 and the temperature measuring probe 31. In another embodiment, as Figure 3 、 Figure 4 shown, a second insulating layer 34 is further provided between the first electrode portion 321 and the temperature measuring probe 31. Specifically, as Figure 3 shown, the first electrode portion 321 is sleeved on the outer periphery of the temperature measuring probe 31, and the second insulating layer 34 is located between the two.

[0059] As a preferred embodiment of the present invention, Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, a mounting portion is provided on the top of the detection component 3, a mounting position 12 is provided on the side of the cover body 1 facing away from the inner cover 2, the cover body 1 is provided with a through hole 13 for the detection component 3 to pass through, and a sealing ring 4 is also provided between the detection component 3 and the cover body 1 to seal the gap between the through hole 13 and the detection component 3.

[0060] The top of the detection assembly 3 is fixedly connected to the cover body 1, and the detection assembly 3 extends downward through the cover body 1. The installation position 12 is located on the side of the cover body 1 away from the inner cover 2, so that the gas and liquid in the pot cannot reach the installation position 12, thereby ensuring the connection stability of the installation structure of the detection assembly 3 and the cover body 1, and preventing the liquid and moist steam from corroding the fixed structure in the installation position 12 and causing the parts to rust, loosen, and other problems. In addition, the sealing ring 4 isolates and seals the upper and lower sides of the cover body 1, and the gas in the pot cannot enter the top of the cover body 1 through the gap between the through hole 13 and the detection assembly 3, thereby ensuring the cleanliness of the inside of the pot cover assembly.

[0061] In one embodiment, the sealing ring 4 is arranged between the outer circumference of the detection component 3 and the inner wall of the through hole 13. During assembly, the sealing ring 4 can be sleeved on the outer circumference of the detection component 3 first, and then the detection component 3 is passed through the through hole 13, so that the sealing ring 4 seals the gap between the outer circumference of the detection component 3 and the inner wall of the through hole 13 under the extrusion effect. At the same time, the sealing ring 4 is deformed by the extrusion, and the friction between the sealing ring 4 and the inner wall of the through hole 13 is increased, thereby improving the fixing stability of the detection component 3 and preventing the detection component 3 from being pushed out of the through hole 13 by the gas in the pot.

[0062] In another embodiment, if Figure 6 As shown, the detection assembly 3 has a fixed flange 37 located above the cover body 1, and the sealing ring 4 is arranged between the fixed flange 37 and the cover body 1. The sealing ring 4 is arranged here to reduce the difficulty of assembly and prevent the sealing ring 4 from being subjected to excessive extrusion force and causing excessive deformation and loss of or reduction of sealing performance.

[0063] Specifically, Figure 2 , Figure 4 As shown, the first electrode portion 321 and the second electrode portion 322 are respectively provided with an electrical plug 36 , and the electrical plug 36 is located above the cover body 1 for electrical connection.

[0064] like Figure 2 As shown, the mounting position 12 is provided with an upwardly protruding fixing protrusion, and the top of the detection component 3 is provided with a fixing rib 35. The fixing protrusion is fastened to the fixing rib 35 by screws or other means to fix the detection component 3 and the cover body 1.

[0065] The power connection plug 36 and the fixing rib 35 are arranged out of alignment to avoid interference during power connection or fixing.

[0066] In a preferred embodiment, as Figure 5 , Figure 6 shown, the pot lid assembly further includes a seal 5 fixed to the rim of the through opening 21. The seal 5 surrounds the through opening 21 and has a sealing lip 51 extending upward, and the sealing lip 51 abuts against the lid body 1 for sealing.

[0067] The sealing lip 51 abuts against the lid body 1 for sealing, so that the lid body 1, the seal 5 and the inner lid 2 cooperate to enclose a detection channel. Gas, bubbles, liquid, etc. in the pot can enter the detection channel through the through opening 21 and contact the temperature measuring probe 31 and the anti-overflow detection member 32. However, since the seal 5 abuts against the lid body 1 and the inner lid 2 for sealing respectively, gas and the like cannot enter the inside of the pot lid assembly, thus ensuring the cleanliness inside the pot lid assembly. At the same time, the seal 5 is fixed to the inner lid 2, so it can be removed together with the inner lid 2, which is convenient for the user to clean the seal 5.

[0068] However, the present utility model does not limit the assembly manner of the inner lid 2. It can be a structure that can be detached from the lid body 1 or a structure that cannot be detached from the lid body 1. Of course, the seal 5 can also be fixed to the lid body 1, so that the sealing lip 51 extends downward to abut against the inner lid 2 to form a seal.

[0069] Preferably, as Figure 7 shown, the detection assembly 3 is arranged out of alignment with the center of the inner lid 2.

[0070] Usually, the exhaust valve 11 is arranged deviating from the center of the pot lid assembly. During cooking, the heat of the heating device is more concentrated in the center of the cooking space. Therefore, the food at the center reaches boiling relatively earlier and boils more violently. However, at the initial stage of boiling, although the liquid in the pot has boiled, there will be no liquid and bubbles reaching the exhaust valve 11, and there is no risk of overflow. Therefore, by eccentrically arranging the detection assembly 3 on the inner lid 2, the anti-overflow detection member 32 can be triggered to conduct only when the liquid at the position where the detection assembly 3 is located boils, and at this time the control unit makes a reaction. In this way, it can be avoided that the heating device is shut down prematurely, resulting in a reduction in heating efficiency. On the basis of reducing the risk of overflow, the heating efficiency is ensured and the user experience is improved.

[0071] Preferably, the detection assembly 3 and the exhaust valve 11 are arranged on the same side of the pot lid assembly to reduce the distance between them, so that the detection assembly 3 can accurately detect the temperature and boiling condition at the exhaust valve 11, thereby better coping with the overflow situation.

[0072] Of course, the detection assembly 3 can also be coaxially arranged with the inner lid 2, which is not limited herein.

[0073] The present utility model also discloses a cooking appliance, which includes a pot body having a cooking cavity, and further includes the above-mentioned lid assembly; a temperature measuring probe 31 passes through the through opening 21 and extends into the cooking cavity, and at least partial regions of the first electrode portion 321 and the second electrode portion 322 extend into the cooking cavity.
