[0041] Traditional cooking utensils often overflow during cooking. To prevent this, they are equipped with anti-overflow devices. However, these devices can pose a safety hazard to users when they operate the utensils, affecting their user experience.

[0042] Therefore, this utility model embodiment designs a cooking appliance 100 suitable for controlling the operation of the arc generating device 5 when the lid assembly 3 is in the closed state, and controlling the arc generating device 5 to stop working when the lid assembly 3 is in the open state. On the one hand, it can avoid energy waste caused by the continuous operation of the arc generating device 5 when the lid is open, and avoid injury caused by contact between the human body and the operating arc generating device 5. On the other hand, it can also ensure that the arc generating device 5 works in time after the lid is closed, and promptly defoam the food in the cooking cavity 110, avoiding the overflow of bubbles, affecting the user experience, causing liquid loss, and affecting the flavor of the cooked food.

[0043] The following is for reference. Figures 1-11 A cooking appliance 100 according to an embodiment of the present utility model is described.

[0044] like Figures 1-4 As shown, the cooking appliance 100 according to the present utility model embodiment may include: a cooking body 1, a lid assembly 3, and an electric arc generating device 5.

[0045] The cooking body 1 includes a pot body 11, which defines a cooking cavity 110 with an opening 1101. Food is cooked in the cooking cavity 110 defined by the pot body 11. The user puts food into the cooking cavity 110 through the opening 1101. After the food boils, the boiling bubbles generated also overflow outward through the opening 1101 of the cooking cavity 110.

[0046] The lid assembly 3 is movably disposed on the cooking body 1 and is used to open and close the opening 1101. When the lid assembly 3 opens the opening 1101, the user can put food into the cooking cavity 110 through the opening 1101. When the lid assembly 3 closes the opening 1101, the lid assembly 3 and the pot body 11 together define a closed cooking cavity 110. During the cooking process, the food in the cooking cavity 110 is continuously heated and generates a large number of bubbles. The bubbles will overflow out of the pot body 11 through the opening 1101 and overflow out of the cooking appliance 100 through the gap between the lid assembly 3 and the pot body 11 and the venting structure provided on the lid assembly 3. This will not only cause dirt on the cooking surface, but also cause moisture loss in the cooking cavity 110, affecting the cooking effect of the food.

[0047] An electric arc generating device 5 is provided on the cooking body 1 or the lid assembly 3, and the electric arc generating device 5 includes a discharge section 51 for generating a bubble-breaking electric arc in the cooking cavity 110. The electric arc generating device 5 of this application achieves bubble breaking by generating a bubble-breaking electric arc at the discharge section 51.

[0048] The electric arc generator 5 produces an electric arc, along with light and heat energy. The electric arc and light energy effectively reduce the surface tension of the bubble wall, accelerating its rupture. When the extremely high temperature comes into contact with the bubble, the gas inside expands rapidly, causing a sudden increase in pressure and thus breaking the bubble.

[0049] Furthermore, under certain conditions, during the formation of the electric arc, the plasma expands at high speed, forming shock waves and directional airflows that directly impact the bubble wall, disrupting the bubble's stability, causing the bubble wall to deform, and ultimately leading to the bubble's rupture.

[0050] The electric arc degassing method, with its concentrated and high-intensity energy, directly targets the bubbles generated after boiling, causing them to break rapidly. Compared to traditional mechanical degassing wheels or blowers, electric arc degassing can process more bubbles in a shorter time, improving degassing efficiency. Because electric arc degassing acts directly on the bubbles through energy conversion without physical contact, it leaves no rice water or other residues inside the equipment. This reduces cleaning difficulty and avoids hygiene problems caused by mold growth from residues.

[0051] The heat generated by the electric arc discharge is released into the pot body 11, which helps to heat food and reduces overall energy consumption. Compared with the noise of traditional blower-type bubble-breaking devices, electric arc bubble breaking only produces a slight ionization sound, improving the user experience. Furthermore, compared with traditional bubble-breaking devices, electric arc bubble breaking avoids direct contact between the device and the bubbles, reducing cleaning difficulty.

[0052] Arc degassing technology is not limited by factors such as the heating power of the rice cooker or the viscosity of the food, and can maintain a stable degassing effect under various cooking conditions. Whether cooking rice, porridge, or even ingredients that are prone to burning, it can effectively prevent foam from overflowing. Arc degassing technology can complete the degassing process in a short time and also reduces the safety hazards caused by prolonged high-temperature operation.

[0053] In summary, using an electric arc to break bubbles and prevent overflow not only improves the efficiency of bubble breaking and reduces residues, but also has strong adaptability and high safety.

[0054] Furthermore, refer to Figure 11 The cooking appliance 100 also includes a lid opening and closing detection component 4 and a control device 6. The lid opening and closing detection component 4 is used to detect the opening and closing state of the lid assembly 3 on the cooking body 1. The control device 6 is adapted to control the electric arc generating device 5 to work when the lid assembly 3 is in the closed state, and to control the electric arc generating device 5 to stop working when the lid assembly 3 is in the open state.

[0055] The control device 6 controls the operation of the arc generator 5 according to the state of the cover assembly 3. On the one hand, it can avoid the energy waste caused by the continuous operation of the arc generator 5 when the cover is open, and accurately supply power only when the cover is closed, eliminating the ineffective energy consumption when the cover is open, extending the equipment life, and also preventing the human body from coming into contact with the arc generator 5 in operation and causing injury. On the other hand, it can also ensure that the arc generator 5 works in time after the cover is closed, and promptly defoam the food in the cooking cavity 110, preventing bubbles from overflowing, affecting the user experience, causing liquid loss, and affecting the flavor of the cooked food.

[0056] In summary, the cooking appliance 100 of this utility model not only effectively defoams and prevents overflow, but also takes into account the user's requirements for safety during the operation of the cooking appliance 100, thereby improving the user experience.

[0057] According to the embodiment of the present utility model, the cooking appliance 100 has a more efficient anti-overflow and anti-bubble function. It can use an electric arc to perform anti-bubble and anti-overflow treatment while ensuring user safety. It can cook food faster and the cooked food is more delicious, thus improving the user experience.

[0058] like Figures 1-4 As shown, the electric arc generating device 5 is located on the cover assembly 3, which facilitates the electric arc generating device 5 to break bubbles in the food in the cooking cavity 110 through the opening 1101 of the cooking cavity 110, and avoids the structural complexity caused by placing the electric arc generating device 5 on the cooking body 1, thus simplifying the structure of the pot body 11 and helping to reduce the production cost of the cooking appliance 100.

[0059] The discharge unit 51 is located on the side of the lid assembly 3 facing the cooking chamber 110 to generate a bubble-breaking arc in the upper part of the cooking chamber 110. The upper part of the cooking chamber 110 can include the upper space within the cooking chamber 110 or the space located above the cooking chamber 110. Positioning the discharge unit 51 on the side of the lid assembly 3 facing the cooking chamber 110 maximizes the arc effect generated by the discharge unit 51, achieving close-range bubble breaking. The discharge unit 51 is placed directly above the cooking chamber 110, minimizing the distance between the arc generation point and the boiling liquid surface. By shortening the physical distance between the arc and the bubbles, the energy transfer efficiency of the arc is significantly enhanced, causing the bubbles to be broken before they reach the pot opening.

[0060] The lid opening and closing detection component 4 can detect the opening and closing status of the lid assembly 3 of the cooking appliance 100 by detecting whether the connection between the lid assembly 3 and the cooking body 1 is broken, or by detecting the posture of the lid assembly 3, or by detecting the steam flow at the vent, etc. The opening and closing status information of the lid assembly 3 is not limited here.

[0061] When both the opening / closing detection component 4 and the arc generating device 5 are mounted on the cover assembly 3, integrating the opening / closing detection component 4 and the arc generating device 5 into one unit simplifies the structure of the cover assembly 3 and optimizes costs.

[0062] Specifically, by placing the opening and closing cover detection component 4 in the arc generating device 5, the use of independent sensors can be reduced, the overall structure of the cooking appliance 100 can be simplified, the number of production parts and production costs of the cooking appliance 100 can be reduced, complex signal transmission lines can be avoided, the complexity of circuit design can be reduced, the number of failure points can be reduced, and the reliability of the internal control system of the cooking appliance 100 can be improved.

[0063] In some embodiments, the lid opening and closing detection component 4 can directly control the circuit connection state of the arc generating device 5. The two are directly related and can achieve real-time linkage. When the lid assembly 3 closes the opening 1101, the arc generating device 5 is activated instantly to generate an arc to break bubbles. When the lid assembly 3 opens the opening 1101, the arc generating device 5 is immediately disconnected from the power supply to realize the power-off processing of the arc generating device 5. This eliminates the delay generated during the control process, and the cooking appliance 100 can cook more safely and reliably, completely avoiding the risk of users coming into contact with live parts.

[0064] Furthermore, when the cover opening and closing detection component 4 can directly act on the control circuit of the arc generating device 5, the control process has better anti-interference ability and can avoid misjudgment caused by other reasons.

[0065] Furthermore, integrating the lid opening / closing detection component 4 with the arc generating device 5 into one unit allows for a more efficient, concise, and aesthetically pleasing spatial layout on the lid assembly 3. Within the limited space of the lid assembly 3, integrating the lid opening / closing detection component 4 with the arc generating device 5 also avoids them occupying additional space within the cooking cavity 110. This integrated modular design also reduces assembly steps during production, facilitating mass production and subsequent maintenance of the cooking appliance 100.

[0066] Integrating the two into one unit can also reduce the difficulty of cleaning cooking utensils by 100%, reduce exposed parts, reduce the risk of residue adhesion, and meet hygiene requirements.

[0067] In some embodiments, the state of the cover assembly can be detected by the different characteristics of the arc circuit itself in the open and closed states, such as impedance changes, thus achieving pure circuit integration without additional sensors.

[0068] Combination Figures 6-10In the embodiment shown, the opening / closing cover detection component 4 and the arc generating device 5 can be integrated by defining a receiving cavity 511 within the discharge section 51 and placing the opening / closing cover detection component 4 within the receiving cavity 511 defined by the discharge section 51 to achieve integration between the two.

[0069] Specifically, the lid opening and closing detection component 4 includes a trigger 41 and a sensor 42. The trigger 41 is disposed in the receiving cavity 511 and switches between a first state and a second state as the lid assembly 3 opens and closes. The sensor 42 is used to generate a sensing signal when the trigger 41 is in the first state to determine that the lid assembly 3 is in one of the open state and the closed state, and to determine that the lid assembly 3 is in the other of the open state and the closed state when the trigger 41 is in the second state.

[0070] The trigger 41 is located in the receiving cavity 511 and switches between the first state and the second state during the opening and closing process of the cover assembly 3. The state switching of the trigger 41 can not only be reflected in the change of the position of the trigger 41, but also in various different state changes such as volume, resistance, gas and liquid state. The change of the trigger 41 between the first state and the second state only needs to meet two conditions: first, the state change of the trigger 41 between the first state and the second state can be sensed by the sensing element 42; second, the trigger 41 can and can only change its state between the first state and the second state during the opening and closing process of the cover assembly 3. There are no restrictions here.

[0071] In some embodiments, the second state is a non-first state, and the sensor 42 can be used only to sense whether the trigger 41 is in the first state to determine whether the trigger 41 is in the first state or the second state. Alternatively, the sensor 42 can be used only to sense whether the trigger 41 is in the second state to determine whether the trigger 41 is in the first state or the second state.

[0072] Specifically, the sensor 42 is used to generate a sensing signal when the trigger 41 is in a first state to determine that the cover assembly 3 is in one of the open state and the closed state, and when the trigger 41 is in a second state to determine that the cover assembly 3 is in the other of the open state and the closed state.

[0073] In some embodiments, the sensor 42 is used to generate a sensing signal when the trigger 41 is in a first state to determine that the cover assembly 3 is in a closed state. When the cover assembly 3 opens the opening 1101, the trigger 41 switches from the first state to the second state. The sensor 42 cannot obtain the state information of the trigger 41, so it can be determined that the trigger 41 is in the second state, which is not the first state, that is, the cover assembly 3 is in an open state.

[0074] In other embodiments, the sensor 42 is used to generate a sensing signal when the trigger 41 is in the first state to determine that the cover assembly 3 is in the open state. When the cover assembly 3 closes the opening 1101, the trigger 41 switches from the first state to the second state. The sensor 42 cannot obtain the state information of the trigger 41, so it can be determined that the trigger 41 is in the second state which is not the first state, and thus it can be determined that the cover assembly 3 is in the closed state.

[0075] Combination Figures 6-10 In the embodiment shown, the switching of the trigger 41 between the first state and the second state is driven by its own gravity, and the change between the first state and the second state is a change in the position of the trigger 41.

[0076] Specifically, the trigger 41 is adapted to switch between a first state and a second state under the action of gravity as the cover assembly 3 opens and closes. The position of the discharge section 51 differs between the open and closed positions of the cover assembly 3, and the position of the defined receiving cavity 511 also differs. These different positions change the positional relationship between the trigger 41 and the receiving cavity 511, corresponding to different states of the trigger 41. The state switching of the trigger 41 is directly related to the opening and closing angle of the cover assembly 3. When the cover assembly 3 opens and closes, the tilt of the receiving cavity 511 triggers the gravitational displacement of the trigger 41. The state feedback of the trigger 41 is delay-free, avoiding interference or delay problems in electronic signal transmission.

[0077] The trigger 41 achieves state switching based on its own gravity, eliminating the need for springs, motors, or other power sources, thus reducing the mechanical complexity of the cooking appliance 100 and lowering the failure rate. The trigger 41 changes its state by gravity, requiring no continuous power supply to the lid opening / closing detection component 4; it only triggers the signal through physical contact during state switching, further reducing energy consumption. Gravity is a constant force, naturally resistant to interference, and unaffected by cooking environments such as temperature, steam, and oil stains, avoiding misjudgments caused by steam condensation or dirt in traditional sensors, resulting in more accurate detection results from the lid opening / closing detection component 4. The trigger 41 employs a gravity-based mechanical structure, such as a metal slider or ball bearing, which prevents performance degradation or damage to electronic components caused by high cooking temperatures, such as high-temperature steam, or corrosive liquids, such as acidic broths, extending the lifespan of the cooking appliance 100 and making it suitable for high-temperature, high-pressure environments such as pressure cookers.

[0078] Therefore, at the instant the cover assembly 3 is opened, the trigger 41 can immediately switch to another state due to gravity, directly cutting off the power supply to the arc generating device 5, eliminating the safety hazard caused by the arc generating device 5 continuing to work due to the delay of the control signal after the cover is opened, and greatly reducing the possibility of users coming into contact with live parts.

[0079] In some practical application scenarios, when the lid assembly 3 of the cooking appliance 100 closes the opening 1101 of the cooking cavity 110, the discharge part 51 is vertically downward, and the trigger 41 falls into the bottom of the receiving cavity 511 due to gravity and contacts the electrode, thus conducting the circuit of the arc generating device 5. When the lid assembly 3 is lifted, the discharge part 51 tilts, and the trigger 41 moves away from the electrode under the action of gravity, and the circuit is automatically disconnected.

[0080] The state switching of the gravity-driven trigger 41 has advantages in safety, reliability, cost control and environmental adaptability, and is especially suitable for cooking scenarios with high temperature, high humidity and lots of stains.

[0081] Reference Figures 6-10 The cover opening and closing detection component 4 further includes: a first signal connection part 43 and a second signal connection part 44. Both the second signal connection part 44 and the first signal connection part 43 are connected to the sensing element 42 and are arranged at intervals. In the first state, the trigger element 41 is connected to the first signal connection part 43 and the second signal connection part 44, and in the second state, it is spaced apart from at least one of the first signal connection part 43 and the second signal connection part 44 to disconnect the first signal connection part 43 and the second signal connection part 44.

[0082] By controlling the connection between the first signal connection part 43 and the second signal connection part 44 through the state control of the trigger 41, precise and reliable circuit control can be achieved. The trigger 41 directly connects or disconnects the first signal connection part 43 and the second signal connection part 44 through physical conduction or disconnection, forming a clear circuit on / off state and avoiding misjudgment. This ensures that the arc generating device 5 only activates when the lid assembly 3 completely closes the opening 1101 of the cooking cavity 110, and immediately cuts off power after the lid is opened, eliminating potential safety hazards for the user. The contact between the trigger 41 and the first and second signal connection parts 44 is purely physical circuit control, requiring no analog-to-digital conversion or signal amplification, reducing control layers and improving response speed. In the disconnected state, the circuit is completely physically isolated, eliminating the need to maintain a low-power detection signal, further reducing energy consumption.

[0083] By replacing electronic components such as Hall sensors and photoelectric switches with mechanical contacts of the first and second signal connection parts 44, only metal contacts or conductive triggers 41, such as copper sheets or magnetic sliders, need to be provided at the first and second signal connection parts 44. No matching chips or precision circuits are required, which reduces the hardware cost in the production process of cooking utensils 100.

[0084] The trigger 41 and the first and second signal connection parts 44 can be integrated into the receiving cavity 511 defined by the conductive part of the arc generating device 5 to form an independent functional module, reducing assembly steps and improving production line efficiency.

[0085] like Figure 6 and Figure 7As shown, the trigger 41 is fixedly connected to the first signal connection part 43, that is, the first signal connection part 43 and the trigger 41 are kept connected. The signal connection between the first signal connection part 43 and the second signal connection part 44 is determined by whether the trigger 41 controls itself to contact the discharge part 51 which is fixedly connected to the second signal connection part 44. When the second signal connection part 44 connects to the first signal connection part 43, the arc generating device 5 is de-energized.

[0086] The trigger 41 is configured to deform at least partially under gravity, switching between a first state and a second state as the cover assembly 3 opens and closes. During the deformation of the trigger 41 under gravity, the state before and after deformation are the first state and the second state of the trigger 41, respectively.

[0087] In the first state, the trigger 41 contacts the discharge section 51 to make the first signal connection section 43 and the second signal connection section 44 signal connected; in the second state, the trigger 41 is spaced apart from the discharge section 51 to disconnect the first signal connection section 43 and the second signal connection section 44.

[0088] Specifically, when the lid assembly 3 closes the opening 1101 of the cooking cavity 110, the discharge section 51 extends vertically downwards, and the trigger 41 is in the second state. At this time, the direction of gravity on the trigger 41 is the same as the extension direction of the trigger 41 itself. The trigger 41 can be suspended in the receiving cavity 511 and does not contact the wall of the receiving cavity 511, that is, the trigger 41 does not contact the discharge section 51 which is fixedly connected to the second signal connection section 44. The first signal connection section 43 and the second signal connection section 44 are disconnected, and the control module controls the arc generating device 5 to operate and release the arc for bubble breaking.

[0089] As the cover assembly 3 is opened, the direction of the force exerted by gravity on the trigger 41 changes. The direction of gravity points to one side perpendicular to the extension direction of the trigger 41. Since the trigger 41 itself is elastic and one end of the trigger 41 is fixed to the first signal connection part 43, as gravity changes, the end of the trigger 41 away from the first signal connection part 43 bends in the direction of gravity under the action of gravity. Thus, at least part of the trigger 41 deforms under the action of gravity, realizing its switching between the first state and the second state. The trigger 41 switches to the first state.

[0090] When the trigger 41 switches to the first state, it contacts the inner wall of the receiving cavity 511, and the signal between the first signal connection part 43 and the second signal connection part 44 is connected. The control module controls the arc generating device 5 to stop releasing the arc. The residual charge on the discharge part 51 can also be carried away by the trigger 41, preventing the user from being shocked by contacting the discharge part 51 with residual charge, and further improving the safety of the operation of the cooking appliance 100.

[0091] The linkage design of the trigger element 41 with the first signal connection part 43, the second signal connection part 44, and the discharge part 51 achieves structural integration. The contact design of the trigger element 41 and the discharge part 51 deeply integrates the lid opening and closing detection component 4 with the arc generating device 5, saving internal space of the lid assembly 3 and allowing for a more compact internal structure design of the cooking appliance 100. The trigger element 41 adopts an elastic structure sensitive to changes in the direction of gravity, enabling more sensitive detection of whether the lid assembly 3 is in a closed state and improving response speed.

[0092] like Figure 6 and Figure 7 As shown, the receiving cavity 511 is a cylindrical cavity, and the triggering element 41 is an elastic element 412 extending along the axial direction of the cylindrical cavity.

[0093] Specifically, when the cover assembly 3 is closed, the cylindrical cavity extends vertically along its axis. The trigger element 41 is a conductive spring extending vertically, with its top end fixedly connected to the first signal connection part 43. It is suspended and fixed within the cylindrical cavity formed by the receiving cavity 511, relying on the first signal connection part 43. The sidewall of the receiving cavity 511 does not contact the conductive spring. That is, the conductive spring does not contact the discharge part 51 fixedly connected to the second signal connection part 44. When the first signal connection part 43 and the second signal connection part 44 are disconnected, the control module controls the arc generating device 5 to operate and release the arc for bubble breaking.

[0094] As the cover assembly 3 is opened, the axial extension direction of the cylindrical cavity is tilted relative to the vertical direction. The direction of the force of gravity acting on the conductive spring is at an angle to the extension direction of the conductive spring. Since one end of the conductive spring is fixed to the first signal connection part 43, the end of the trigger 41 away from the first signal connection part 43 bends downward under the action of gravity and deforms. The conductive spring switches to the first state and contacts the side wall of the receiving cavity 511 located on the lower side. The signal between the first signal connection part 43 and the second signal connection part 44 is connected, and the control module controls the arc generating device 5 to stop releasing the arc.

[0095] like Figures 8-10 As shown, the first signal connection part 43 and the second signal connection part 44 are fixed in the receiving cavity 511, and the trigger 41 is movably disposed in the receiving cavity 511 so as to switch between the first state and the second state during the opening and closing process of the cover assembly 3.

[0096] As the lid assembly 3 opens and closes, the direction of gravity acting on the trigger 41 changes relative to the extension direction of the receiving cavity 511. When the lid assembly 3 closes the opening 1101 of the cooking cavity 110, the direction of gravity acting on the trigger 41 points away from the lid assembly 3. When the lid assembly 3 opens the opening 1101 of the cooking cavity 110, the direction of gravity acting on the trigger 41 points towards the lid assembly 3. Therefore, the trigger 41 is adapted to move within the receiving cavity 511 according to the direction of gravity. This movement enables switching between a first state and a second state.

[0097] In the first state, the trigger 41 contacts the first signal connection portion 43 and the second signal connection portion 44 to make the first signal connection portion 43 and the second signal connection portion 44 signal connected; in the second state, the trigger 41 is spaced apart from both the first signal connection portion 43 and the second signal connection portion 44 to disconnect the first signal connection portion 43 and the second signal connection portion 44.

[0098] In some embodiments, such as Figure 9 and Figure 10 As shown, when the trigger 41 is in the first state, the corresponding cover assembly 3 can be in the open state; when the trigger 41 is in the second state, the corresponding cover assembly 3 can be in the closed state.

[0099] In other embodiments, reference is made to Figure 8 When the trigger 41 is in the first state, the corresponding cover assembly 3 can be in the closed state. When the trigger 41 is in the second state, the corresponding cover assembly 3 can be in the open state.

[0100] Specifically, when the opening 1101 of the cooking cavity 110 is closed by the cover assembly 3, the extension direction of the discharge part 51 extends vertically away from the cover assembly 3, and the direction of gravity points away from the cover assembly 3. The trigger 41 provided in the receiving cavity 511 moves to one end of the receiving cavity 511 away from the cover assembly 3. When the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 away from the cover assembly 3, the trigger 41 is in the first state. When the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 close to the cover assembly 3, the trigger 41 is in the second state.

[0101] When the opening 1101 of the cooking cavity 110 of the lid assembly 3 is open, and the lid assembly 3 is rotated to a certain angle, the direction of gravity of the trigger 41 points toward the side of the lid assembly 3. The trigger 41 provided in the receiving cavity 511 moves to one end of the receiving cavity 511 near the lid assembly 3. When the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 away from the lid assembly 3, the trigger 41 is in the second state. When the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 near the lid assembly 3, the trigger 41 is in the first state.

[0102] In some embodiments, when the cover assembly 3 closes the opening 1101 of the cooking cavity 110, the extension direction of the receiving cavity 511 defined by the discharge section 51 extends in the vertical direction. At this time, the cover assembly 3 can only make the gravity direction of the trigger 41 point to the cover assembly 3 when the opening angle is greater than 90°, and the trigger 41 can switch to another state under the action of gravity.

[0103] In other embodiments, when the lid assembly 3 closes the opening 1101 of the cooking cavity 110, the discharge part 51 extends from top to bottom in a direction away from the axis of rotation of the lid assembly 3. Thus, when the lid assembly 3 is opened at an angle of less than 90°, the direction of gravity of the trigger 41 can be directed towards the lid assembly 3, and the trigger 41 can switch to another state under the action of gravity.

[0104] According to some embodiments of this utility model, refer to Figure 9 and Figure 10 The receiving cavity 511 is a cylindrical cavity, and the first signal connection part 43 and the second signal connection part 44 are arranged side by side in the receiving cavity 511, and are closer to the cover assembly 3 than the trigger 41.

[0105] The trigger 41 is a spherical structure 411, and the diameter of the spherical structure 411 is greater than or equal to the distance between the first signal connection part 43 and the second signal connection part 44.

[0106] The trigger 41 is a spherical structure 411, the diameter of which is greater than or equal to the distance between the first signal connection portion 43 and the second signal connection portion 44. This prevents the trigger 41 from moving further between the two portions after it contacts their ends, thus causing it to become stuck between them and unable to switch back to the second state.

[0107] According to some other embodiments of this utility model, such as Figure 8As shown, the receiving cavity 511 is a cylindrical cavity. The first signal connection part 43 and the second signal connection part 44 are arranged side by side in the receiving cavity 511. An insulating material slide rail is provided between the first signal connection part 43 and the second signal connection part 44. The trigger 41 is located in the slide rail and moves along the extension direction of the slide rail.

[0108] At least a portion of the first signal connection part 43 and the second signal connection part 44 bends and extends into the slide rail, and can receive the trigger part that slides to the end of the slide rail at the end. After the trigger 41 moves to the end of the slide rail, it simultaneously contacts the first signal connection part 43 and the second signal connection part 44, and connects the first signal connection part 43 and the second signal connection part 44.

[0109] The trigger 41 is a spherical structure 411. The diameter of the spherical structure 411 is smaller than the closest distance between the first signal connection part 43 and the second signal connection part 44, so that the trigger 41 can be limited by the first signal connection part 43 and the second signal connection part 44 after moving to the end of the slide rail.

[0110] The trigger element 41 is a conductive sphere, which can be a metal sphere or a conductive semiconductor sphere, etc.

[0111] According to some embodiments of this utility model, such as Figures 1-4 As shown, the cover assembly 3 includes: a cover body 31 and a cover plate assembly 32.

[0112] The cover assembly 32 is detachably disposed on the side of the cover body 31 facing the cooking cavity 110. The cover assembly 32 can isolate the cover body 31, which has a complex structure and integrates multiple different electrical structures, from the high temperature, high pressure and high humidity cooking cavity 110, so as to avoid the high temperature, high pressure and high humidity environment in the cooking cavity 110 from affecting the normal operation of the electrical structure on the cover body 31.

[0113] An electric arc generating device 5 is disposed inside the cover body 31 to facilitate the circuit design of the internal electrical structure of the cooking appliance 100. The discharge part 51 of the electric arc generating device 5 extends toward the cooking cavity 110. The cover plate assembly 32 has a through hole 321 for the discharge part 51 to pass through, so as to ensure that the discharge part 51 can extend to the side of the cover plate assembly 32 away from the cover body 31 and discharge outward to generate a bubble-breaking electric arc in the upper part of the cooking cavity 110. The side of the cover body 31 facing the cover plate assembly 32 has a through hole 312 opposite to the through hole 321. A sealing ring 313 is provided at the through hole 312. The discharge part 51 is disposed at the through hole 312 and contacts and cooperates with the sealing ring 313.

[0114] A sealing ring 313 surrounds the discharge section 51 to ensure a tight seal between the discharge section 51 and the cover body 31, preventing steam or air bubbles from entering the interior of the cover body 31 through the gap between the discharge section 51 and the cover body 31, thus affecting electrical safety. The sealing ring 313 also provides a certain degree of protection. Specifically, because it is made of insulating material, it provides insulation between the cover body 31 and the discharge section 51, improving safety. Furthermore, the sealing ring 313 engages with the cover plate assembly 32. This engagement, with a sealed seal, prevents water vapor from entering between the cover plate assembly 32 and the cover body 31.

[0115] According to some embodiments of this utility model, refer to Figures 1-4 The cover plate assembly 32 is provided with a steam outlet 322, and the cover body 31 is provided with an exhaust valve 314. The exhaust valve 314 defines an exhaust channel 3140, which connects the external space of the cover body 31 and the steam outlet 322.

[0116] Steam vent 322 is located on the removable cover assembly 32, allowing users to directly remove the cover assembly 32 to clean the steam vent 322 and surrounding residues such as rice water and grease, avoiding cleaning dead spots caused by the complex structure of traditional one-piece covers. The exhaust channel 3140 is defined by the exhaust valve 314 on the cover body 31, forming a one-way path from the steam vent 322 to the outside, avoiding heat loss or local pressure imbalance caused by random steam diffusion, and ensuring the fluid flow direction in the cooking cavity 110. The cover body 31 carries the exhaust valve 314 and possibly integrated circuits, such as the power supply structure of the arc generator 5, while the cover assembly 32 only has the steam vent 322, ensuring effective isolation between high-temperature and high-humidity steam and electronic components, reducing the risk of short circuits.

[0117] According to some embodiments of this utility model, refer to Figure 5 The cooking appliance 100 also includes a heating element 12, which is located below the pot body 11 and is used to heat the pot body 11.

[0118] In the prior art, the bubble-breaking and anti-overflow device installed in the cooking appliance 100 uses mechanical bubble breaking, which has low bubble breaking efficiency and poor bubble breaking effect. In order to achieve anti-overflow, it is usually necessary to sacrifice the heating power of the cooking appliance 100, which affects the flavor of the food.

[0119] This application utilizes the electric arc generated by the discharge section 51 of the electric arc generator 5 to break up bubbles in the cooking cavity 110 and prevent overflow, thereby improving the overflow prevention effect of the cooking appliance 100, achieving high-efficiency bubble breaking, and ensuring that the cooking appliance 100 will not overflow even under intense and continuous boiling.

[0120] Therefore, when the cooking appliance 100 is in the boiling stage, the control device 6 can control the arc generating device 5 to work and control the heating element 12 to maintain high power operation.

[0121] Since the cooking appliance 100 does not need to reduce its operating power to prevent overflow, the boiling process during cooking can be more intense and continuous, improving the cooking effect and reducing the cooking time. On the other hand, the electric arc can process the food, which is conducive to the production of Maillard reaction in the food, making the cooked food more delicious.

[0122] According to the embodiments of the present invention, the cooking appliance 100 has a more efficient anti-overflow and anti-bubbling function, can perform high-power continuous boiling treatment on food, can cook food faster, and the cooked food is more delicious.

[0123] In some embodiments, the arc generating device 5 includes a circuit control board 53, a primary coil, a secondary coil, and a discharge section 51. The primary coil and the secondary coil are arranged opposite to each other, with the primary coil connected to the circuit control board 53 and the secondary coil connected to the discharge section 51. In other embodiments, the arc generating device 5 further includes a heat dissipation device 52 and a heat insulation plate 54. The heat dissipation device 52 is disposed on the circuit control board 53 to dissipate heat from the circuit control board 53, and the heat insulation plate 54 is disposed between the secondary coil and the discharge section 51 to prevent the heat generated by the discharge section 51 from being transferred to the secondary coil.

[0124] A specific embodiment of the cooking utensil 100 is described below with reference to the accompanying drawings.

[0125] like Figures 1-4 As shown, the cooking appliance 100 includes: a cooking body 1, a lid assembly 3, a lid opening and closing detection component 4, an electric arc generating device 5, and a control device 6.

[0126] The cooking body 1 includes a pot body 11, which defines a cooking cavity 110 with an opening 1101. Food is cooked in the cooking cavity 110 defined by the pot body 11. The user puts food into the cooking cavity 110 through the opening 1101. After the food boils, the boiling bubbles generated also overflow outward through the opening 1101 of the cooking cavity 110.

[0127] The lid assembly 3 is movably disposed on the cooking body 1 and is used to open and close the opening 1101. When the lid assembly 3 opens the opening 1101, the user can put food into the cooking cavity 110 through the opening 1101. When the lid assembly 3 closes the opening 1101, the lid assembly 3 and the pot body 11 together define a closed cooking cavity 110.

[0128] An arc generating device 5 is located on the cover assembly 3. The arc generating device 5 includes a circuit control board 53, a heat dissipation device 52 and a primary coil on the circuit control board 53, a heat insulation plate 54 and a secondary coil and a discharge part 51 on the heat insulation plate 54. The heat insulation plate 54 and the circuit control board 53 are arranged at intervals.

[0129] The discharge section 51 is located on the side of the cover assembly 3 facing the cooking cavity 110. The discharge section 51 is used to generate a bubble-breaking arc in the cooking cavity 110. The arc generating device 5 achieves bubble breaking by generating a bubble-breaking arc at the discharge section 51.

[0130] Reference Figure 11 The cooking appliance 100 also includes a lid opening / closing detection component 4 and a control device 6. The lid opening / closing detection component 4 is used to detect the opening / closing state of the lid assembly 3 on the cooking body 1. The control device 6 is adapted to control the arc generating device 5 to work when the lid assembly 3 is in the closed state, and to control the arc generating device 5 to stop working when the lid assembly 3 is in the open state. The control device 6 controls the operation of the arc generating device 5 through the state of the lid assembly 3. On the one hand, it can avoid the energy waste caused by the continuous operation of the arc generating device 5 when the lid is open, and accurately supply power only when the lid is closed, eliminating ineffective energy consumption when the lid is open, extending the life of the equipment, and also preventing the human body from contacting the operating arc generating device 5 and causing injury. On the other hand, it can also ensure that the arc generating device 5 works in time after the lid is closed, and promptly defoam the food in the cooking cavity 110, avoiding the overflow of bubbles, affecting the user experience, causing liquid loss, and affecting the flavor of the cooked food.

[0131] like Figures 1-4 The cover assembly 3 includes a cover body 31 and a cover plate assembly 32. The cover plate assembly 32 is detachably disposed on the side of the cover body 31 facing the cooking cavity 110. An arc generating device 5 is disposed inside the cover body 31 to facilitate the circuit design of the internal electrical structure of the cooking appliance 100. The discharge part 51 of the arc generating device 5 extends towards the cooking cavity 110. The cover plate assembly 32 has a through hole 321 for the discharge part 51 to pass through, so as to ensure that the discharge part 51 can extend to the side of the cover plate assembly 32 away from the cover body 31 and discharge outward to generate a bubble-breaking arc in the upper part of the cooking cavity 110. The side of the cover body 31 facing the cover plate assembly 32 has a through hole 312 opposite to the through hole 321. A sealing ring 313 is provided at the through hole 312. The discharge part 51 is disposed at the through hole 312 and contacts and cooperates with the sealing ring 313.

[0132] A sealing ring 313 surrounds the discharge section 51 to ensure a tight seal between the discharge section 51 and the cover body 31, preventing steam or air bubbles from entering the interior of the cover body 31 through the gap between the discharge section 51 and the cover body 31, thus affecting electrical safety. The sealing ring 313 also provides a certain degree of protection. Specifically, because it is made of insulating material, it provides insulation between the cover body 31 and the discharge section 51, improving safety. Furthermore, the sealing ring 313 engages with the cover plate assembly 32. This engagement, with a sealed seal, prevents water vapor from entering between the cover plate assembly 32 and the cover body 31.

[0133] According to some embodiments of the present invention, the cover plate assembly 32 is provided with a steam outlet 322, and the cover body 31 is provided with an exhaust valve 314. The exhaust valve 314 defines an exhaust channel 3140, which connects the external space of the cover body 31 and the steam outlet 322.

[0134] The following is combined Figure 6 and Figure 7 The accompanying drawings illustrate a specific embodiment of the internal structure of the discharge section 51.

[0135] The discharge section 51 defines a receiving cavity 511. The opening and closing cover detection component 4 is disposed in the receiving cavity 511 defined by the discharge section 51. The opening and closing cover detection component 4 includes a trigger 41 and a sensor 42. The sensor 42 includes a first signal connection part 43 and a second signal connection part 44. The trigger 41 is disposed in the receiving cavity 511 and switches between a first state and a second state by its own gravity as the driving force during the opening and closing process of the cover assembly 3. The sensor 42 is used to generate a sensing signal when the trigger 41 is in the first state.

[0136] The trigger 41 is fixedly connected to the first signal connection part 43, that is, the first signal connection part 43 and the trigger 41 are kept connected. The signal connection between the first signal connection part 43 and the second signal connection part 44 is determined by whether the trigger 41 controls itself to contact the discharge part 51 which is fixedly connected to the second signal connection part 44. When the second signal connection part 44 connects to the first signal connection part 43, the arc generating device 5 is de-energized.

[0137] The trigger 41 is configured to deform at least partially under gravity, switching between a first state and a second state as the cover assembly 3 opens and closes. During the deformation of the trigger 41 under gravity, the state before and after deformation are the first state and the second state of the trigger 41, respectively.

[0138] When the trigger 41 is in the first state, the trigger 41 contacts the discharge part 51 so that the first signal connection part 43 and the second signal connection part 44 are connected in signal.

[0139] When the trigger 41 is in the second state, the trigger 41 is spaced apart from the discharge section 51 to disconnect the first signal connection section 43 and the second signal connection section 44.

[0140] Specifically, when the lid assembly 3 closes the opening 1101 of the cooking cavity 110, the discharge section 51 extends vertically downwards, and the trigger 41 is in the second state. At this time, the direction of gravity on the trigger 41 is the same as the extension direction of the trigger 41 itself. The trigger 41 can be suspended in the receiving cavity 511 and does not contact the wall of the receiving cavity 511, that is, the trigger 41 does not contact the discharge section 51 which is fixedly connected to the second signal connection section 44. The first signal connection section 43 and the second signal connection section 44 are disconnected, and the control module controls the arc generating device 5 to operate and release the arc for bubble breaking.

[0141] As the cover assembly 3 is opened, the direction of the force exerted by gravity on the trigger 41 changes. The direction of gravity points to one side perpendicular to the extension direction of the trigger 41. Since the trigger 41 itself is elastic and one end of the trigger 41 is fixed to the first signal connection part 43, as gravity changes, the end of the trigger 41 away from the first signal connection part 43 bends in the direction of gravity under the action of gravity. Thus, at least part of the trigger 41 deforms under the action of gravity, realizing its switching between the first state and the second state. The trigger 41 switches to the first state.

[0142] When the trigger 41 switches to the first state, it contacts the inner wall of the receiving cavity 511, and the signal between the first signal connection part 43 and the second signal connection part 44 is connected. The control module controls the arc generating device 5 to stop releasing the arc. The residual charge on the discharge part 51 can also be carried away by the trigger 41, preventing the user from being shocked by contacting the discharge part 51 with residual charge, and further improving the safety of the operation of the cooking appliance 100.

[0143] The linkage design of the trigger element 41 with the first signal connection part 43, the second signal connection part 44, and the discharge part 51 achieves structural integration. The contact design of the trigger element 41 and the discharge part 51 deeply integrates the lid opening and closing detection component 4 with the arc generating device 5, saving internal space of the lid assembly 3 and allowing for a more compact internal structure design of the cooking appliance 100. The trigger element 41 adopts an elastic structure sensitive to changes in the direction of gravity, enabling more sensitive detection of whether the lid assembly 3 is in a closed state and improving response speed.

[0144] According to some embodiments of the present invention, the receiving cavity 511 is a cylindrical cavity, and the triggering member 41 is an elastic member 412 extending axially along the cylindrical cavity.

[0145] Specifically, when the cover assembly 3 is closed, the cylindrical cavity extends vertically along its axis. The trigger element 41 is a conductive spring extending vertically, with its top end fixedly connected to the first signal connection part 43. It is suspended and fixed within the cylindrical cavity formed by the receiving cavity 511, relying on the first signal connection part 43. The sidewall of the receiving cavity 511 does not contact the conductive spring. That is, the conductive spring does not contact the discharge part 51 fixedly connected to the second signal connection part 44. When the first signal connection part 43 and the second signal connection part 44 are disconnected, the control module controls the arc generating device 5 to operate and release the arc for bubble breaking.

[0146] As the cover assembly 3 is opened, the axial extension direction of the cylindrical cavity is tilted relative to the vertical direction. The direction of the force of gravity acting on the conductive spring is at an angle to the extension direction of the conductive spring. Since one end of the conductive spring is fixed to the first signal connection part 43, the end of the trigger 41 away from the first signal connection part 43 bends downward under the action of gravity and deforms. The conductive spring switches to the first state and contacts the side wall of the receiving cavity 511 located on the lower side. The signal between the first signal connection part 43 and the second signal connection part 44 is connected, and the control module controls the arc generating device 5 to stop releasing the arc.

[0147] The following is combined Figures 8-10 The accompanying drawings illustrate two other specific embodiments of the internal structure of the discharge section 51.

[0148] like Figure 8 As shown, the first signal connection part 43 and the second signal connection part 44 are fixed in the receiving cavity 511, and the trigger 41 is movably disposed in the receiving cavity 511 to switch between the first state and the second state as the cover assembly 3 opens and closes.

[0149] As the lid assembly 3 opens and closes, the direction of gravity acting on the trigger 41 changes relative to the extension direction of the receiving cavity 511. When the lid assembly 3 closes the opening 1101 of the cooking cavity 110, the direction of gravity acting on the trigger 41 points away from the lid assembly 3. When the lid assembly 3 opens the opening 1101 of the cooking cavity 110, the direction of gravity acting on the trigger 41 points towards the lid assembly 3. Therefore, the trigger 41 is adapted to move within the receiving cavity 511 according to the direction of gravity. This movement enables switching between a first state and a second state.

[0150] In the first state, the trigger 41 contacts the first signal connection portion 43 and the second signal connection portion 44 to make the first signal connection portion 43 and the second signal connection portion 44 signal connected; in the second state, the trigger 41 is spaced apart from both the first signal connection portion 43 and the second signal connection portion 44 to disconnect the first signal connection portion 43 and the second signal connection portion 44.

[0151] In some embodiments, refer to Figure 9 and Figure 10 When the trigger 41 is in the first state, the corresponding cover assembly 3 can be in the open state. When the trigger 41 is in the second state, the corresponding cover assembly 3 can be in the closed state.

[0152] Specifically, when the opening 1101 of the cooking cavity 110 is closed by the cover assembly 3, the extension direction of the discharge part 51 extends vertically away from the cover assembly 3, and the direction of gravity points away from the cover assembly 3. The trigger 41 provided in the receiving cavity 511 moves to the end of the receiving cavity 511 away from the cover assembly 3. When the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 close to the cover assembly 3, the trigger 41 is in the second state.

[0153] When the opening 1101 of the cooking cavity 110 is open in the lid assembly 3, and the lid assembly 3 is rotated to a certain angle, the direction of gravity of the trigger 41 points toward the side facing the lid assembly 3. When the trigger 41 located in the receiving cavity 511 moves to one end of the receiving cavity 511 near the lid assembly 3, and the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 near the lid assembly 3, the trigger 41 is in the first state.

[0154] like Figure 9 and Figure 10 The receiving cavity 511 is a cylindrical cavity, and the first signal connection part 43 and the second signal connection part 44 are arranged side by side in the receiving cavity 511, and are closer to the cover assembly 3 than the trigger 41.

[0155] The trigger 41 is a spherical structure 411, the diameter of which is greater than or equal to the distance between the first signal connection portion 43 and the second signal connection portion 44. This prevents the trigger 41 from moving further between the two portions after it contacts their ends, thus causing it to become stuck between them and unable to switch back to the second state.

[0156] Reference Figure 8In other embodiments, when the trigger 41 is in the first state, the corresponding cover assembly 3 can be in the closed state, and when the trigger 41 is in the second state, the corresponding cover assembly 3 can be in the open state.

[0157] Specifically, when the opening 1101 of the cooking cavity 110 is closed by the cover assembly 3, the extension direction of the discharge part 51 extends vertically away from the cover assembly 3, and the direction of gravity points away from the cover assembly 3. The trigger 41 provided in the receiving cavity 511 moves to the end of the receiving cavity 511 away from the cover assembly 3. When the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 away from the cover assembly 3, the trigger 41 is in the first state.

[0158] When the opening 1101 of the cooking cavity 110 is open in the lid assembly 3, and the lid assembly 3 is rotated to a certain angle, the direction of gravity of the trigger 41 points toward the side facing the lid assembly 3. When the trigger 41 located in the receiving cavity 511 moves to one end of the receiving cavity 511 close to the lid assembly 3, and the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 away from the lid assembly 3, the trigger 41 is in the second state.

[0159] The receiving cavity 511 is a cylindrical cavity. The first signal connection part 43 and the second signal connection part 44 are arranged side by side in the receiving cavity 511. An insulating material slide rail is provided between the first signal connection part 43 and the second signal connection part 44. The trigger 41 is located in the slide rail and moves along the extension direction of the slide rail.

[0160] At least a portion of the first signal connection part 43 and the second signal connection part 44 bends and extends into the slide rail, and can receive the trigger part that slides to the end of the slide rail at the end. After the trigger 41 moves to the end of the slide rail, it simultaneously contacts the first signal connection part 43 and the second signal connection part 44, and connects the first signal connection part 43 and the second signal connection part 44.

[0161] The trigger 41 is a spherical structure 411 with a diameter smaller than the closest distance between the first signal connection part 43 and the second signal connection part 44, so that the trigger 41 can be limited by the first signal connection part 43 and the second signal connection part 44 after moving to the end of the slide rail.
