[0002] Traditional cooking appliances often overflow during cooking. To address this, they are equipped with anti-overflow devices that break bubbles. However, the anti-overflow devices used in current technology are not very effective. Even under intense and continuous boiling, overflow can still occur. Therefore, cooking appliances need to actively reduce their operating power to prevent overflow.

[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] The following is for reference. Figures 1-8 This invention describes a cooking appliance 100 according to an embodiment of the present invention. The cooking appliance 100 may be a pressure cooker, rice cooker, or electric slow cooker, etc.

[0039] Reference Figure 1 and Figure 2According to an embodiment of the present invention, the cooking appliance 100 includes a cooking body 10 and a lid assembly 20. The cooking body 10 includes a pot body 11, which defines a cooking cavity 12 with an opening. The lid assembly 20 is movably disposed on the cooking body 10 for opening and closing the opening. Here, the lid assembly 20 can be rotatably connected to the cooking body 10, so that the lid assembly 20 can rotate between an open position and a closed position; the lid assembly 20 can be detachably fitted to the cooking body 10.

[0040] When the lid assembly 20 is opened, the user can add ingredients or remove food from the cooking cavity 12 through the opening. When the lid assembly 20 is closed, the lid assembly 20 and the pot body 11 together define a relatively enclosed cooking cavity 12, allowing food to be cooked. For example, as... Figure 1 As shown, the cooking appliance 100 can be a pressure cooker, with the lid assembly 20 detachably attached to the cooking body 10. For example, as... Figure 2 As shown, the cooking appliance 100 can be a rice cooker, and the lid assembly 20 is pivotally mounted on the cooking body 10.

[0041] During the cooking process, the food inside the cooking cavity 12 is continuously heated and generates a large number of bubbles. These bubbles will overflow outside the cooking appliance 100 through the venting structure (such as an exhaust valve) provided on the lid assembly 20. This will not only cause dirt on the cooking surface, but also cause moisture loss inside the cooking cavity 12, affecting the cooking effect of the food.

[0042] Reference Figure 1 and Figure 2 In this application, the cooking appliance 100 also includes a bubble-breaking device 30, which includes an arc-generating device 31. The arc-generating device 31 is disposed on the cover assembly 20 or the cooking body 10, and can generate a bubble-breaking arc in the upper part of the cooking cavity 12. The upper part of the cooking cavity 12 may include the upper space inside the cooking cavity 12, or it may include the space located above the cooking cavity 12.

[0043] The electric arc generating device 31 can generate an electric arc, accompanied by the generation of light and heat energy. The electric arc and light energy can effectively reduce the surface tension of the bubble wall and accelerate the bubble wall rupture. When extremely high temperatures come into contact with the bubble, the gas inside the bubble will expand rapidly due to heat, causing a sudden increase in pressure inside the bubble, thereby achieving bubble rupture. 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, destroying the bubble's stability, causing the bubble wall to deform, and ultimately causing the bubble to rupture.

[0044] In other words, the high-intensity, concentrated energy of the electric arc degassing method can directly act on the bubbles generated after boiling, causing them to break rapidly. Compared to other methods, electric arc degassing can process more bubbles in a shorter time, improving degassing efficiency. Because the electric arc acts directly on the bubbles through energy conversion without physical contact, it does not leave rice water or other residues inside the equipment. This reduces cleaning difficulty and avoids hygiene problems caused by mold growth from residues.

[0045] During the cooking process, the electric arc generator 31 can discharge according to the cooking program settings. For example, it can discharge continuously or intermittently during the set cooking stage. Whether cooking rice or porridge, or even cooking ingredients that are prone to burning, it can complete the bubble breaking process in a short time, effectively preventing foam overflow and reducing the safety hazards caused by prolonged high-temperature operation.

[0046] When the discharge section 313 can come into contact with the food, the temperature at the end of the electric arc can instantly reach over 120°C. Due to the skin effect of the high-frequency and high-voltage electric arc, it penetrates deep into the food and can generate a high temperature on the surface of the food. The temperature surface reaches the Maillard reaction temperature, which can enhance the aroma of the food.

[0047] In addition, after the cooking appliance 100 has finished cooking and been cleaned, a low-temperature plasma or electric arc with a set frequency and power can be generated in the cooking cavity 12 using the electric arc generator 31, thereby sterilizing, disinfecting and deodorizing the cooking cavity 12.

[0048] Therefore, by setting up the electric arc generating device 31, not only can the effect of breaking bubbles and preventing overflow be achieved, but the cooking cavity 12 can also be sterilized and disinfected. When the discharge part 313 comes into contact with the food, it can also enhance the aroma of the food and improve the cooking effect.

[0049] Reference Figures 3-5 The arc generating device 31 includes a transformer 311, a control circuit module 312, and a discharge section 313. The transformer 311 can be an air-core transformer. The transformer 311 includes a primary coil 3111 and a secondary coil 3112, which are arranged opposite to each other and spaced apart. The control circuit module 312 can be a plate-shaped structure or other structures. The control circuit module 312 is connected to the primary coil 3111 and is used to induce a voltage in the secondary coil 3112. The discharge section 313 is connected to the secondary coil 3112 and generates a bubble-breaking arc in the upper part of the cooking cavity 12.

[0050] Specifically, the control circuit module 312 can instantaneously turn the current in the primary coil 3111 on or off, causing the magnetic field around the primary coil 3111 to change rapidly, and the magnetic flux to change accordingly. The changing magnetic flux passes through the secondary coil 3112, thereby inducing a voltage in the secondary coil 3112. When the voltage in the secondary coil 3112 rises to a level sufficient to break down the air, the air is completely ionized, forming a plasma channel. A large amount of current passes through the plasma channel, generating high temperature and intense light, i.e., forming an electric arc at the discharge section 313, thereby performing bubble-breaking treatment in the upper part of the cooking cavity 12.

[0051] According to the embodiment of the present invention, the cooking appliance 100 is equipped with an arc generating device 31 on the lid assembly 20. The arc generating device 31 generates a bubble-breaking arc in the upper part of the cooking chamber 12. On the one hand, it can improve the anti-overflow effect of the cooking appliance 100 and achieve large-area bubble breaking. Through the high-efficiency bubble breaking and anti-overflow effect, it is ensured that the cooking appliance 100 will not overflow even under violent and continuous boiling. The cooking appliance 100 does not need to reduce its operating power, and the boiling process during cooking can be more violent and continuous, improving the cooking effect and reducing the cooking time. On the other hand, the arc can process the food, which is conducive to the Maillard reaction of the food, making the cooked food more delicious.

[0052] Furthermore, by configuring the arc generating device 31 to include a transformer 311, a control circuit module 312, and a discharge section 313, the arc generating device 31 has the characteristics of small size and simple circuit structure, which facilitates the installation of the arc generating device 31 on the cover assembly 20 and avoids increasing the size of the cooking appliance 100.

[0053] like Figure 2 and Figure 3 As shown, according to some embodiments of the present invention, an arc generating device 31 is provided on the cover assembly 20, a primary coil 3111 and a secondary coil 3112 are arranged at intervals in the thickness direction of the cover assembly 20, and a discharge part 313 protrudes from the side of the cover assembly 20 facing the cooking cavity 12.

[0054] Therefore, by placing the arc generating device 31 on the lid assembly 20, the arc generating device 31 can avoid the pot body 11 with a high temperature, and it is also conducive to the arrangement of the discharge part 313, so that the arc generating device 31 can form an arc in the upper part of the cooking cavity 12, which is conducive to realizing the bubble breaking and overflow prevention function.

[0055] Reference Figure 4 and Figure 5According to some embodiments of the present invention, the arc generating device 31 further includes a first heat insulation member 314, which is disposed on the side of the secondary coil 3112 away from the primary coil 3111, and the discharge part 313 is at least partially located on the side of the first heat insulation member 314 away from the secondary coil 3112.

[0056] That is, the first heat insulation element 314 is located between the secondary coil 3112 and the discharge part 313, and the first heat insulation element 314 is located between the secondary coil 3112 and the cooking cavity 12.

[0057] This configuration reduces the transfer of heat from the cooking cavity 12 to the secondary coil 3112, preventing heat from ultimately being transferred to the control circuit module 312 and causing it to malfunction. This helps ensure the stability of the control circuit module 312 and extends its service life.

[0058] Reference Figure 2 and Figure 3 In some embodiments, the cover assembly 20 includes an inner cover 21 and a top cover 22, with the top cover 22 disposed on the side of the inner cover 21 away from the cooking cavity 12.

[0059] The arc generating device 31 is located between the inner cover 21 and the top cover 22, and the discharge part 313 passes through the inner cover 21. By placing the arc generating device 31 between the inner cover 21 and the top cover 22, the arc generating device 31 can be protected, reducing the probability of damage to the arc generating device 31. On the other hand, the main structure of the arc generating device 31 (such as the transformer 311 and the control circuit module 312) can be kept as far away as possible from the cooking cavity 12, avoiding heat transfer to the control circuit module 312, which would cause the control circuit module 312 to malfunction.

[0060] Reference Figure 3 In some examples, the first heat insulation element 314 and the inner cover 21 are formed separately, and the first heat insulation element 314 is located between the inner cover 21 and the secondary coil 3112. By forming the first heat insulation element 314 and the inner cover 21 separately, the manufacturing difficulty of the first heat insulation element 314 and the inner cover 21 can be reduced, making it easier to design the first heat insulation element 314 flexibly, and facilitating repair and replacement when the first heat insulation element 314 or the inner cover 21 is damaged.

[0061] In some other examples not shown in the figure, the first heat insulation element 314 is integrally formed with the inner cover 21. By making the first heat insulation element 314 and the inner cover 21 integrally formed, on the one hand, the connection step between the first heat insulation element 314 and the inner cover 21 can be eliminated, improving production efficiency and reducing production costs. On the other hand, the overall structural strength of the first heat insulation element 314 and the inner cover 21 can be improved, reducing the failure of the first heat insulation element 314 due to loose connection, and improving the reliability of the arc generating device 31.

[0062] In some examples, the cover assembly 20 also includes a cover plate assembly 23 disposed on the side of the inner cover 21 facing the cooking cavity 12. That is, in the thickness direction of the cover assembly 20, the inner cover 21 is located between the cover 22 and the cover plate assembly 23. The discharge section 313 passes through the inner cover 21 and the cover plate assembly 23.

[0063] Furthermore, the cooking appliance 100 also includes an insulating element disposed between the cover assembly 23 and the discharge section 313. Since the cover assembly 23 is typically a metal structure, by providing an insulating element between the cover assembly 23 and the discharge section 313, the cover assembly 23 and the discharge section 313 can be insulated and isolated, reducing the energy absorbed by the cover assembly 23 from the discharge section 313, and also improving safety.

[0064] Reference Figure 3 In some specific examples, the inner cover 21 has a first through hole 211, and the insulating element includes a sealing ring 24, which is disposed at the first through hole 211. The discharge part 313 is disposed through the first through hole 211, that is, the sealing ring 24 surrounds the discharge part 313, and the sealing ring 24 is located between the hole wall of the first through hole 211 and the discharge part 313.

[0065] The cover plate assembly 23 has a second through hole 231, which is opposite to the first through hole 211. The discharge part 313 passes through the second through hole 231, and the sealing ring 24 surrounds the outer periphery of the second through hole 231 and abuts against the cover plate assembly 23.

[0066] In the above technical solution, the sealing ring 24 surrounds the discharge part 313. On the one hand, this ensures a tight seal between the discharge part 313 and the inner cover 21, preventing steam or bubbles from entering the space between the inner cover 21 and the top cover 22 through the first perforation 211, thus affecting electrical safety. On the other hand, it reduces the absorption of arc energy released by the discharge part 313 by the cover assembly 23, which helps ensure the anti-overflow effect of the arc generating device 31. In addition, the sealing ring 24 and the cover assembly 23 engage in a stop-and-go fit, preventing steam or bubbles from entering the space between the cover assembly 23 and the inner cover 21 through the second perforation 231.

[0067] Reference Figure 4 and Figure 5According to some embodiments of the present invention, the arc generating device 31 further includes a second heat insulation member 315, which is disposed on the side of the primary coil 3111 away from the secondary coil 3112, and the control circuit module 312 is at least partially located on the side of the second heat insulation member 315 away from the primary coil 3111.

[0068] In other words, the second heat insulation component 315 is located between the primary coil 3111 and the control circuit module 312. This arrangement reduces the heat transfer from the primary coil 3111 to the control circuit module 312, preventing the control circuit module 312 from malfunctioning. This helps ensure the operational stability of the control circuit module 312 and extends its service life.

[0069] Reference Figure 5 According to some embodiments of the present invention, the arc generating device 31 further includes a heat dissipation component 316, which is disposed on the side of the control circuit module 312 away from the primary coil 3111.

[0070] For example, the heat dissipation component 316 can be a cooling fan. The cooling fan can be located on the same side as the components of the control circuit module 312 to increase the airflow speed on the side where the components of the control circuit module 312 are located, thereby improving the heat dissipation efficiency of the components of the control circuit module 312 and enabling the control circuit module 312 to work normally.

[0071] For example, the heat dissipation component 316 can be a heat sink, which can be located on the same side as the components of the control circuit module 312, thereby dissipating heat from the components of the control circuit module 312 and enabling the control circuit module 312 to operate normally. The heat sink has multiple heat sink fins, which increases the contact area between the heat sink and the air, thus better dissipating heat from the components of the control circuit module 312.

[0072] Therefore, in the above technical solution, by providing a heat dissipation component 316 on the side of the control circuit module 312 away from the primary coil 3111, the heat dissipation component 316 is used to dissipate heat from the components of the control circuit module 312, preventing the components of the control circuit module 312 from failing to work properly due to overheating, which is beneficial to improving the stability of the operation of the control circuit module 312 and extending the service life of the control circuit module 312.

[0073] Reference Figure 4 and Figure 5According to some embodiments of this utility model, the control circuit module 312 includes a high-frequency oscillation component 3121, which is connected to the primary coil 3111 and is used to turn the primary coil 3111 on or off to induce a voltage in the secondary coil 3112. The voltage induced by the secondary coil 3112 is subjected to air self-feedback to achieve self-excited oscillation, and the self-excited oscillation causes the discharge section 313 to form an open circuit with the air, thereby generating an electric arc.

[0074] In some embodiments, the high-frequency oscillation component 3121 includes a transistor (not shown) connected to the primary coil 3111. The transistor can not only amplify weak electrical signals, but also be used as an electronic switch. By periodically turning it on and off, it controls the current flow in the high-frequency oscillation component 3121, thereby generating a high-frequency oscillation signal and realizing signal oscillation and output.

[0075] The cooking appliance 100 also includes a temperature sensor and a controller. The temperature sensor is used to detect the temperature of the transistor. When the temperature sensor detects that the temperature of the transistor is greater than or equal to a preset temperature, the controller is used to control the transistor to cut off the power.

[0076] This configuration can prevent the transistor from being damaged due to its temperature exceeding the operating temperature, and can achieve overheat protection for the high-frequency oscillation component 3121, which is beneficial to extending the service life of the high-frequency oscillation component 3121.

[0077] It should be noted that when the transistor loses power, it can be linked with the cooking program of the cooking appliance 100, so that the cooking appliance 100 can switch to the set program after detecting that the transistor has lost power.

[0078] Reference Figure 3 In some embodiments, the length L of the discharge section 313 extending out of the cover plate assembly 23 is 1cm-10cm. In some specific embodiments, the length of the discharge section 313 extending out of the cover plate assembly 23 is 5cm-8cm. For example, the length of the discharge section 313 extending out of the cover plate assembly 23 can be 5cm, 6cm, 7cm, 8cm, etc.

[0079] In the above technical solution, by limiting the length of the discharge part 313 extending out of the cover plate assembly 23 to meet the above range, on the one hand, the electric arc energy generated by the discharge part 313 is not easily absorbed by the cover plate assembly 23, and on the other hand, the discharge part 313 is closer to the maximum water level line of the pot body 11. On the basis of a certain discharge frequency, it can ensure that the discharge energy of the electric arc is sufficient, thereby improving the bubble breaking and overflow prevention function of the cooking utensil 100.

[0080] Reference Figure 2 and Figure 6According to some embodiments of the present invention, the cooking appliance 100 further includes a cooking container 40, which is detachably disposed inside the pot body 11, and the cooking container 40 is spaced apart from the bottom wall of the pot body 11. The discharge part 313 extends at least partially into the cooking container 40 to contact the food inside the cooking container 40.

[0081] Specifically, when using the cooking utensil 100, the user can choose whether or not to use the cooking container 40. If the cooking container 40 is not needed, the ingredients can be placed directly into the pot body 11 for cooking. If the cooking container 40 is needed, it can be supported inside the pot body 11, and the ingredients can be placed into the pot body 11 and the cooking container 40 for cooking separately, or the ingredients can be placed only into the cooking container 40 for cooking.

[0082] When cooking container 40 is required, refer to Figure 2 The cooking container 40 can be supported on the rim of the pot body 11, with the bottom of the cooking container 40 spaced apart from the bottom wall of the pot body 11. (See reference...) Figure 6 The cooking container 40 can be supported on the bottom wall of the pot body 11 by the support member 41, so that the bottom of the cooking container 40 is spaced apart from the bottom wall of the pot body 11. Of course, the cooking container 40 can also be installed in the pot body 11 in other ways.

[0083] Furthermore, the cooking container 40 is insulated from the pot body 11. Specifically, at least one of the cooking container 40 and the pot body 11 can be made of insulating material, such as the cooking container 40 being a glass container, a ceramic container, or a plastic container; or an insulating layer can be provided on the surface of at least one of the cooking container 40 and the pot body 11; or the cooking container 40 can be supported on the pot body 11 by an insulating support member, so that there is no electrical conductivity between the cooking container 40 and the pot body 11, and the arc generating device 31 can be electrically connected to the pot body 11 after discharge.

[0084] In the above technical solution, the user can choose whether to use the cooking container 40. By using the cooking container 40, the height of the food can be raised and the food can be kept out of contact with the pot body 11. When the discharge part 313 comes into contact with the food and the electric arc generating device 31 works, the electric arc generated by the discharge part 313 will not be absorbed by the pot body 11, but can penetrate into the food and generate a high temperature on the surface of the food, reaching the Maillard reaction temperature, which enhances the aroma of the food without needing to change the length of the discharge part 313.

[0085] In some embodiments not shown in the figures, the cooking appliance 100 also includes a conductive component, one end of which is detachably connected to the discharge unit 313, and the other end extends into the pot body 11 to contact the food inside the pot body 11.

[0086] It should be noted that, in this embodiment, in order to prevent the arc generating device 31 from being electrically connected to the pot body 11 after discharge, and thus causing the arc energy generated by the arc generating device 31 to be absorbed by the pot body 11, the pot body 11 can be made of insulating material, such as a glass pot or a ceramic pot; or, an insulating layer can be provided on the surface of the pot body 11.

[0087] When using the cooking appliance 100, the user can choose whether to use the conductive accessory as needed. If the conductive accessory is not needed, there is a certain distance between the discharge unit 313 and the food inside the pot body 11. If the conductive accessory is needed, it can be connected to the discharge unit 313, and the conductive accessory can be used to guide the electric arc to a deeper part inside the pot body 11.

[0088] In the above technical solution, the user can choose whether to use conductive accessories. By using conductive accessories, the length of the discharge part 313 can be extended, allowing the conductive accessories to come into contact with the food. In this way, the electric arc generated by the discharge part 313 can be guided into the food through the conductive accessories, causing the surface of the food to generate a higher temperature, reaching the Maillard reaction temperature, and enhancing the aroma of the food.

[0089] Reference Figure 7 and Figure 8 According to some embodiments of the present invention, the bubble-breaking device 30 further includes a blower 32, which is disposed on the cover assembly 20 and is used to drive air to flow into the cooking cavity 12 for bubble breaking.

[0090] When the cooking appliance 100 is working, the blower 32 can be controlled to work in the preset cooking stage. The blower 32 can drive air to flow into the cooking cavity 12. The flowing air directly impacts the bubble wall, destroying the stability of the bubble, causing the bubble wall to deform, and eventually the bubble bursts.

[0091] For example, the blower 32 may include a fan. When the fan rotates, the fan blades drive airflow to form an airflow, which impacts the bubbles, achieving a bubble-breaking effect. Furthermore, the fan rotation generates a low-pressure zone, which increases the pressure difference between the inside and outside of the bubbles, thereby achieving pressure-differential bubble breaking. Of course, the blower 32 can also have other structural forms.

[0092] In the above technical solution, by setting up the blower 32, the stability of the bubbles can be disrupted, thereby achieving the effect of breaking bubbles and preventing overflow.

[0093] Reference Figure 7 and Figure 8According to some embodiments of the present invention, the bubble-breaking device 30 further includes a heating element 33, which is disposed on the cover assembly 20 and is used to heat the air in the upper part of the cooking cavity 12 to break bubbles. The upper part of the cooking cavity 12 may include the upper space inside the cooking cavity 12, or it may include the space located above the cooking cavity 12.

[0094] When the cooking appliance 100 is in operation, the heating element 33 can be controlled to work during the preset cooking stage. When the extremely high temperature comes into contact with the bubbles, the gas inside the bubbles will expand rapidly due to the heat, causing a sudden increase in pressure inside the bubbles, thereby breaking the bubbles. For example, the heating element 33 can use high temperature to degrease and crack the walls of bubbles with a lot of oil, thereby achieving rapid bubble breaking.

[0095] For example, refer to Figure 7 The heating element 33 can be an electromagnetic heating element 33, and the bubble-breaking effect can be adjusted by increasing the heating power and heating temperature. For example, refer to... Figure 8 The heating element 33 can be a film heating element 33, which can better achieve the effect of thermal energy debubbling by utilizing its rapid high temperature characteristics.

[0096] According to other embodiments of the present invention, the bubble-breaking device 30 further includes a blower 32 and a heating element 33, both of which are disposed on the cover assembly 20, so that the blower 32 and the heating element 33 can break bubbles when they are working. By employing multiple bubble-breaking methods, the efficiency of bubble-breaking and overflow prevention can be greatly improved.
