Detailed Implementation

[0065] Embodiments of the present invention 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 the present invention, and should not be construed as limiting the present invention.

[0066] The following is for reference. Figures 1-11 A method for controlling a cooking appliance 100 according to an embodiment of the present invention is described.

[0067] Reference Figure 1 According to an embodiment of the present invention, a cooking appliance 100 includes a cooking body 10 and a lid assembly 20. The cooking body 10 includes a pot body 11 and a heating device 12. The pot body 11 defines a cooking cavity 12 with an opening. The heating device 12 is used to heat the bottom of the pot body 11. The lid assembly 20 is movably disposed on the cooking body 10 and is used to open and close 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 engaged with the cooking body 10.

[0068] When the lid assembly 20 is opened, the user can put ingredients into the cooking cavity 12 or take out food through the opening of the cooking cavity 12. When the lid assembly 20 is closed, the lid assembly 20 and the pot body 11 together define a relatively closed cooking cavity 12, so that the ingredients can be cooked.

[0069] Reference Figure 1 The cooking appliance 100 also includes a venting device 50, which can be located on the lid assembly 20 or the cooking body 10, for venting.

[0070] Reference Figure 1 The cooking appliance 100 also includes a bubble-breaking device 30, at least one of 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] Among them, such as Figure 2 As shown, the method for controlling the cooking appliance 100 includes the following steps:

[0078] S100: The cooking stage of acquiring cooking utensils;

[0079] S200: Controls the start and stop of the bubble-breaking device and the venting device according to the current cooking stage of the cooking appliance.

[0080] Specifically, the cooking appliance 100 here can be a pressure cooker. The cooking stages of the pressure cooker may include heating stage, pressure holding stage and pressure release stage (or venting stage), etc. The working status of the bubble breaking device 30 and the venting device 50 can be controlled according to the current cooking stage of the pressure cooker, so as to meet the needs of different cooking stages.

[0081] For example, this pressure cooker can be used to cook porridge or rice. During the cooking process, the bubble-breaking device 30 and the venting device 50 can be controlled to operate during the pressure-holding and pressure-releasing stages to prevent overflow. For example, this pressure cooker can be used to make soup. During the soup-making process, the bubble-breaking device 30 and the venting device 50 can be controlled to operate during the pressure-holding and pressure-releasing stages to prevent overflow.

[0082] Therefore, the control method of the cooking appliance 100 according to the embodiment of the present invention controls whether the bubble-breaking device 30 and the venting device 50 work according to the current cooking stage of the cooking appliance 100. The bubble-breaking device 30 can be used to break bubbles and prevent overflow in a specific cooking stage, and the venting device 50 can be used to vent air in a specific cooking stage, thereby meeting the needs of different cooking stages and improving the cooking effect and cooking efficiency of the cooking appliance 100.

[0083] like Figure 3As shown, according to some embodiments of the present invention, the current cooking stage is a first pressure holding stage, which includes a pressure reduction and bubble breaking stage.

[0084] S242: During the depressurization and bubble breaking stage, when the arc generating device is operating, the exhaust device is controlled to exhaust air.

[0085] The exhaust time of the exhaust device 50 is less than or equal to the working time of the arc generating device 31.

[0086] It should be noted that during the depressurization and bubble-breaking stage, controlling the venting device 50 to vent can mean that the venting device 50 vents continuously, intermittently, or continuously for a period of time followed by intermittent venting. The venting duration of the venting device 50 here refers to the total time the venting device 50 is in the open state for venting. If the venting device 50 vents intermittently, this venting duration does not include the time the venting device 50 is closed in between.

[0087] Taking the cooking of porridge in a pressure cooker as an example, during the first pressure-holding stage, the pressure cooker can control the venting device 50 to release air, thereby reducing the pressure inside the cooking chamber 12. This prevents the pressure inside the cooking chamber 12 from becoming too high, thus maintaining the pressure inside the cooking chamber 12 within a lower first preset pressure range. At this time, because less starch is dissolved from the rice grains, the bubbles generated inside the cooking chamber 12 are larger in volume and relatively fewer in number. Therefore, during this stage, the electric arc generating device 31 can also be controlled to work. The electric arc generated by the electric arc generating device 31 makes it easier to prevent overflow and break bubbles, and the effect of preventing overflow and breaking bubbles is better.

[0088] In the above technical solution, during the pressure reduction and bubble breaking stage of the first pressure holding stage, while the arc generating device 31 is working, the exhaust device 50 is controlled to exhaust, and the exhaust time of the exhaust device 50 is limited to be less than or equal to the discharge time of the arc generating device 31. This ensures that the arc generating device 31 is always working while the exhaust device 50 is venting, preventing bubbles from overflowing from the exhaust device 50 during the pressure reduction and exhaust process, which is beneficial to improving the porridge cooking effect of the pressure cooker.

[0089] For example, during the discharge of the electric arc generating device 31, the heating device 13 can be controlled to reduce its power for heating. After the electric arc generating device 31 stops discharging, the heating device 13 can be controlled to resume heating at the specified power, which can improve cooking efficiency and ensure that there is no overflow.

[0090] like Figure 4 As shown, in some embodiments, the first pressure holding stage further includes a pre-venting stage and a pressurization stage, with the depressurization and defoaming stage following the pre-venting stage and preceding the pressurization stage.

[0091] The control method for the cooking appliance 100 to enter the first pressure holding stage includes the following steps:

[0092] S241: Entering the pre-venting stage, the arc generating device is controlled to stop working, and the venting device is controlled to vent until the venting time of the venting device in the pre-venting stage reaches the first preset time.

[0093] Specifically, during the heating phase, when the temperature of the cooking cavity 12 rises to a first preset temperature, the cooking appliance 100 enters a first pressure-holding phase. During the pre-venting phase of the first pressure-holding phase, the venting device 50 can be controlled to continuously or intermittently vent until the total venting time of the venting device 50 in this phase reaches a first preset time, at which point the pre-venting phase ends.

[0094] S242: Enter the pressure reduction and bubble breaking stage, control the arc generating device to work, and control the exhaust device to exhaust, until the working time of the arc generating device in the pressure reduction and bubble breaking stage reaches the second preset time.

[0095] It should be noted that during the pressure reduction and bubble breaking stage of the first pressure holding phase, when the arc generating device 31 is operating, the exhaust device 50 can be controlled to exhaust air. Specifically, the exhaust device 50 can be controlled to continuously or intermittently exhaust air. Furthermore, during this stage, the operating time of the arc generating device 31 is a second preset time, and the total exhaust time of the exhaust device 50 is less than or equal to the second preset time. This ensures that the arc generating device 31 is always operating while the exhaust device 50 is venting air, preventing bubbles from overflowing from the exhaust device 50 during the pressure reduction and exhaust process, thus improving the porridge cooking effect of the pressure cooker.

[0096] S243: Enter the pressure boosting stage, control the heating device to work continuously, and control the arc generating device and exhaust device to stop working, until the working time of the heating device in the pressure boosting stage reaches the third preset time.

[0097] In other words, during this stage, the heating device 13 can be controlled to work continuously, so that the pressure inside the cooking cavity 12 increases, thereby preventing the pressure inside the cooking cavity 12 from becoming too low. This helps to maintain the pressure inside the cooking cavity 12 within the first preset pressure range, thus satisfying the cooking effect of the cooking appliance 100 in the first pressure holding stage.

[0098] Therefore, during the first pressure holding stage, the pressure inside the cooking cavity 12 can be maintained within a smaller first preset pressure range. During this stage, since the number of bubbles generated inside the cooking cavity 12 is small and the bubble volume is large, it is easier to break the bubbles and prevent overflow by controlling the discharge of the electric arc generating device 31.

[0099] like Figure 4As shown, in some embodiments, a second pressure-holding stage follows the first pressure-holding stage. The method for controlling the cooking appliance 100 further includes:

[0100] S244: Confirm whether the total duration of the first pressure holding stage is greater than the fourth preset duration;

[0101] When the total duration of the first pressure holding stage is less than the fourth preset duration, the cooking appliance is controlled to re-enter the first pressure holding stage until the total duration is greater than the fourth preset duration.

[0102] When the total duration of the first pressure holding stage is greater than or equal to the fourth preset duration, control the cooking appliance to enter the second pressure holding stage;

[0103] In other words, during the first pressure holding stage, it can be determined whether the total duration of the first execution of the pre-venting stage, the depressurization and bubble-breaking stage, and the pressure-increasing stage is greater than the fourth preset duration. If the total duration of the first execution of the pre-venting stage, the depressurization and bubble-breaking stage, and the pressure-increasing stage is greater than or equal to the fourth preset duration, then the cooking appliance 100 enters the second pressure holding stage. If the total duration of the first execution of the pre-venting stage, the depressurization and bubble-breaking stage, and the pressure-increasing stage is less than the fourth preset duration, then the cooking appliance 100 repeats the pre-venting stage, the depressurization and bubble-breaking stage, and the pressure-increasing stage until the total duration of the multiple executions of the pre-venting stage, the depressurization and bubble-breaking stage, and the pressure-increasing stage reaches the fourth preset duration.

[0104] S45: During the second pressure holding stage, the heating device is controlled to continue heating, while the arc generating device and the exhaust device are controlled to not work, until the fifth preset time is reached.

[0105] In other words, during the second pressure-holding stage, the pressure inside the cooking chamber 12 can be maintained within a larger second preset pressure range (the second preset pressure range is greater than the first preset pressure range). During this stage, the higher temperature inside the cooking chamber 12 leads to more severe gelatinization of the ingredients, such as increasing the degree of "blooming" of rice grains, thus improving cooking effect and efficiency. Furthermore, during the second pressure-holding stage, due to the severe gelatinization of the ingredients, more starch dissolves, and there are numerous and dense bubbles, making overflow less likely. Therefore, there is no need for bubble-breaking and overflow prevention during this stage, which reduces the operating time of the arc generator 31.

[0106] In summary, by controlling the cooking appliance 100 to maintain pressure in stages—that is, the cooking appliance 100 first enters the first pressure-maintaining stage and then the second pressure-maintaining stage, and controlling the arc generator 31 and the exhaust device 50 to work during the first pressure-maintaining stage—effective spill prevention can be achieved under low-pressure conditions. Conversely, controlling the arc generator 31 and the exhaust device 50 to not work during the second pressure-maintaining stage reduces the risk of damage to the arc generator 31 due to prolonged operation, thus extending its service life. Furthermore, it allows food to be cooked better under high temperature and high pressure, improving the taste and cooking efficiency, shortening cooking time, and achieving highly efficient cooking under high pressure.

[0107] like Figure 5 As shown, in some embodiments, the cooking appliance 100 further includes a pressure relief stage, which is located after the pressure holding stage. That is, the control method of the cooking appliance 100 further includes:

[0108] S240: Entering the pressure holding stage;

[0109] S250: Entering the depressurization stage.

[0110] like Figure 6 As shown, the control method for the cooking appliance 100 also includes:

[0111] S100: The cooking stage of acquiring cooking utensils;

[0112] S250: Entering the pressure relief stage, the arc generating device is controlled to operate, and the exhaust device is controlled to exhaust.

[0113] For example, during the depressurization phase, the venting device 50 is controlled to vent in multiple venting phases. In one venting phase, the arc generating device 31 can be controlled not to discharge. In the next venting phase, the arc generating device 31 can be controlled to discharge. And in the next venting phase, the arc generating device 31 can be controlled not to discharge.

[0114] For example, during the depressurization phase, the exhaust device 50 can be controlled to perform intermittent exhaust (point exhaust), and after the exhaust device 50 stops exhausting, the arc generating device 31 can be controlled to discharge intermittently.

[0115] For example, during the depressurization phase, the arc generating device 31 can be controlled to continuously discharge, and the exhaust device 50 can be controlled to perform intermittent exhaust (point exhaust).

[0116] Therefore, by controlling the exhaust device 50 to exhaust air during the depressurization stage, depressurization can be achieved, and by controlling the operation of the electric arc generating device 31, bubble breaking and overflow prevention can be achieved during the depressurization process.

[0117] like Figure 7As shown, in some embodiments, the depressurization phase includes a first phase and a second phase, and step S250 includes:

[0118] S251: Enter the first stage, control the arc generating device to work, and simultaneously control the exhaust device to exhaust, until the duration of the first stage reaches the sixth preset duration.

[0119] S252: Enter the second stage, control the arc generating device to stop working, and simultaneously control the exhaust device to exhaust or not exhaust, until the duration of the second stage reaches the seventh preset duration.

[0120] In the above technical solution, by controlling the electric arc generating device 31 and the exhaust device 50 at different times during the pressure relief stage, the time of the pressure relief stage can be reduced while ensuring the bubble breaking and overflow prevention effect, thereby reducing the cooking time.

[0121] like Figure 8 As shown, in some embodiments, the pressure inside the cooking cavity 12 is also detected during the depressurization phase;

[0122] Following the second phase, it also includes:

[0123] S253: Determine that the pressure inside the cooking chamber is greater than normal pressure, control the arc generating device to work, and at the same time control the exhaust device to continuously exhaust air until the pressure inside the cooking chamber drops to normal pressure.

[0124] In other words, after the second stage, if the pressure inside the cooking chamber 12 still has not dropped to normal pressure, it is necessary to continue to control the exhaust device 50 to exhaust the air. At the same time, to avoid overflow during the exhaust process, the electric arc generating device 31 can be controlled to work. If the pressure inside the cooking chamber 12 drops to normal pressure, the pressure relief stage is completed and there is no need to exhaust the air. Therefore, the air exhaust device 50 can be stopped to exhaust the air, and the electric arc generating device 31 can be controlled to stop discharging.

[0125] In some specific embodiments, the cooking appliance 100 also includes a stop lever (not shown in the figure), which is adapted to switch between an unlocked lid assembly 20 state and a locked lid assembly 20 state. When the stop lever is in the locked lid assembly 20 state, the pressure in the cooking cavity 12 is greater than normal pressure, and when the stop lever is in the unlocked lid assembly 20 state, the pressure in the cooking cavity 12 is normal pressure.

[0126] In the above technical solution, by setting a stop rod, on the one hand, the pressure inside the cooking cavity 12 can be monitored according to the state of the stop rod, and on the other hand, the state of the stop rod can be linked with the state of the cover assembly 20, so that when the pressure inside the cooking cavity 12 is greater than the normal pressure, the cover assembly 20 cannot be opened, thus ensuring the safety during the use of the cooking utensil 100.

[0127] During the pressure relief phase, the pressure inside the cooking cavity 12 is obtained by detecting the state of the stop lever. This configuration eliminates the need for a separate pressure detection device, enabling pressure monitoring within the cooking cavity 12. This reduces the number of components in the cooking appliance 100, lowers costs, and simplifies the structure of the cooking appliance 100.

[0128] The following describes a specific embodiment of this application. The cooking stage of the cooking appliance 100 includes a heating stage, a pressure holding stage (including a first pressure holding stage and a second pressure holding stage), and a pressure release stage (including a first stage and a second stage).

[0129] When the heating phase begins, the heating device 13 heats the pot body 11. When the temperature of the cooking cavity 12 is greater than or equal to the second preset temperature, the heating device 13 is controlled to stop working. When the temperature of the cooking cavity 12 drops below the third preset temperature, the heating device 13 is controlled to work again. This process is repeated until the tenth preset duration.

[0130] During the heating phase, by limiting the temperature range within the cooking cavity 12 to between the second and third preset temperatures, the water absorption rate of the ingredients can be increased, thereby improving the cooking effect.

[0131] When the temperature inside the cooking cavity 12 reaches the first preset temperature, it enters the first pressure holding stage. In the first pressure holding stage, the cooking appliance 100 first enters the pre-venting stage. In the pre-venting stage, the venting device 50 can be controlled to vent intermittently (point venting), and the arc generating device 31 can be controlled not to work, until the venting time of the venting device 50 in the pre-venting stage reaches the first preset time.

[0132] After the pre-venting stage is completed, the cooking appliance 100 enters the depressurization and bubble-breaking stage. During the depressurization and bubble-breaking stage, the electric arc generating device 31 is controlled to work, and the venting device 50 is controlled to vent until the working time of the electric arc generating device 31 in the depressurization and bubble-breaking stage reaches the second preset time.

[0133] After the depressurization and bubble-breaking stage ends, the cooking appliance 100 enters the pressurization stage. During the pressurization stage, the heating device 13 is controlled to continue heating, and then the arc generating device 31 is controlled not to discharge into the cooking cavity 12. At the same time, the exhaust device 50 is controlled not to exhaust, until the working time of the heating device 13 in the pressurization stage reaches the third preset time.

[0134] When the total duration of the pre-venting stage, depressurization and bubble-breaking stage, and pressurization stage of the first pressure holding phase is less than or equal to the fourth preset duration, the cooking appliance 100 is controlled to repeat the above actions, that is, to repeatedly enter the pre-venting stage, depressurization and bubble-breaking stage, and pressurization stage. When the total duration of the pre-venting stage, depressurization and bubble-breaking stage, and pressurization stage of the first pressure holding phase is greater than the fourth preset duration, the second pressure holding phase is entered. In the second pressure holding phase, the heating device 13 is controlled to continue heating, and the arc generating device 31 is controlled not to discharge into the cooking cavity 12. At the same time, the venting device 50 is controlled not to vent, and this continues for the fifth preset duration.

[0135] After the second pressure holding stage ends, the first stage of the pressure relief stage begins. In the first stage of the pressure relief stage, the arc generating device 31 is controlled to discharge into the cooking cavity 12, while the exhaust device 50 is controlled to exhaust intermittently or continuously. The first stage lasts for a preset duration of six.

[0136] After the first stage of the pressure relief phase ends, the second stage begins. In the second stage of the pressure relief phase, the arc generating device 31 is controlled not to discharge, while the exhaust device 50 is controlled to continuously exhaust, or intermittently exhaust, or not exhaust, for a preset duration of seven times.

[0137] Subsequently, when the stop lever is detected to be in the unlocked state, the pressure relief phase ends. When the stop lever is detected to be in the locked state, the arc generator 31 is controlled to discharge into the cooking cavity 12, and the exhaust device 50 is controlled to continuously exhaust air until the stop lever switches to the unlocked state.

[0138] like Figure 9 As shown, in some embodiments, the current cooking stage is the depressurization stage. Step S200 includes:

[0139] S260: During the pressure relief phase, control the exhaust device to release gas and detect the pressure inside the cooking cavity;

[0140] The operation of the electric arc generating device is controlled according to the pressure inside the cooking cavity.

[0141] Specifically, during the depressurization phase, the exhaust device 50 can be controlled to exhaust at a preset exhaust frequency P0. Specifically, the exhaust device 50 can be controlled to operate for a preset exhaust duration at regular intervals.

[0142] The preset venting duration and venting interval of the venting device 50 can be preset according to different cooking needs. For example, during the pressure relief stage, the venting device 50 can be controlled to vent for one minute every two minutes; or, the venting device 50 can be controlled to vent for two minutes every three minutes.

[0143] During the depressurization phase, the operation of the electric arc generating device 31 is controlled according to the pressure inside the cooking cavity 12. Specifically, the operating parameters of the electric arc generating device 31 can be changed according to the pressure inside the cooking cavity 12.

[0144] For example, the operating parameters of the arc generating device 31 may include the duration of a single discharge of the arc generating device 31, the total duration of discharge of the arc generating device 31, the interval between two adjacent discharges of the arc generating device 31, and the frequency of the high-frequency oscillation component 3121 of the arc generating device 31.

[0145] Once the cooking appliance 100 has completed pressure cooking, it enters the pressure relief stage. The exhaust device 50 can be controlled to release pressure according to a preset program. At the beginning of the pressure relief, the pressure inside the cooking chamber 12 is high, and the risk of overflow is high. As the pressure relief proceeds, the pressure inside the cooking chamber 12 gradually decreases, and the risk of overflow gradually decreases.

[0146] Therefore, during the depressurization stage, by changing the operating parameters of the arc generator 31 according to the pressure inside the cooking cavity 12, the arc generator 31 can discharge according to the preset program. This not only generates a bubble-breaking arc to prevent overflow, but also reduces the problem of overheating of components in the arc generator 31 due to prolonged operation, which can lead to a decrease in the overflow prevention effect or even damage.

[0147] In some embodiments, the arc generating device 31 includes a high-frequency oscillation component 3121.

[0148] like Figure 10 As shown, the operation of the electric arc generating device is controlled according to the pressure inside the cooking cavity, including:

[0149] S261: Control the high-frequency oscillation component to start working at the first frequency P1;

[0150] S262: Obtain the relationship between the pressure in the cooking cavity and the frequency of the high-frequency oscillation component, and control the high-frequency oscillation component to reduce its operating frequency to the corresponding frequency based on the real-time pressure in the cooking cavity;

[0151] S263: Once the pressure inside the cooking chamber drops to normal atmospheric pressure, control the arc generator to stop working.

[0152] In other words, during the pressure relief phase, the high-frequency oscillation component 3121 is first controlled to start working at a first frequency P1. During the continuous operation of the high-frequency oscillation component 3121, the pressure detection device can detect the real-time pressure inside the cooking cavity 12 and match the frequency of the high-frequency oscillation component 3121 in real time, so that the frequency of the high-frequency oscillation component 3121 can be changed in real time. For example, the frequency of the high-frequency oscillation component 3121 can be matched in real time according to the real-time pressure inside the cooking cavity 12 and the preset pressure-frequency curve or table of the cooking cavity 12-frequency of the high-frequency oscillation component 3121, until the pressure inside the cooking cavity 12 drops to normal pressure, at which point the arc generating device 31 can be controlled to stop working.

[0153] As the exhaust device 50 gradually releases air during the pressure relief phase, the pressure inside the cooking chamber 12 gradually decreases, and the pressure difference between the inside and outside of the cooking chamber 12 gradually decreases. Therefore, the overflow situation inside the cooking chamber 12 is gradually alleviated. During this process, the frequency of the high-frequency oscillation component 3121 is reduced in real time according to the pressure inside the cooking chamber 12. On the basis of achieving bubble breaking and overflow prevention, the problem of reduced overflow prevention effect or even damage to components due to overheating can be reduced.

[0154] In some embodiments, the arc generating device 31 includes a high-frequency oscillation component 3121.

[0155] like Figure 11 As shown, the electric arc generating device is controlled to operate according to the pressure inside the cooking cavity, including:

[0156] S261′: Control the arc generating device to operate at a preset frequency every eighth preset time interval for the ninth preset time interval;

[0157] S262′: Obtain the relationship between the pressure in the cooking chamber and the ninth preset duration, and control the high-frequency oscillation component to reduce its operation to the corresponding ninth preset duration based on the real-time pressure in the cooking chamber;

[0158] S263′: Determine that the pressure inside the cooking cavity has dropped to normal pressure, and control the arc generator to stop working.

[0159] In other words, during the pressure relief phase, the high-frequency oscillation component 3121 is first controlled to start working at the first frequency P1. During the cooking process, the pressure detection device can detect the real-time pressure in the cooking cavity 12 and adjust the working time of the high-frequency oscillation component 3121 in real time until the pressure in the cooking cavity 12 drops to normal pressure, at which point the arc generating device 31 can be controlled to stop working.

[0160] As the pressure relief phase progresses, the pressure inside the cooking chamber 12 gradually decreases as the exhaust device 50 gradually releases air, and the pressure difference between the inside and outside of the cooking chamber 12 gradually decreases. As a result, the overflow situation inside the cooking chamber 12 is gradually alleviated. During this process, the working time of the high-frequency oscillation component 3121 is reduced in real time according to the pressure inside the cooking chamber 12. On the basis of achieving bubble breaking and overflow prevention, the problem of reduced overflow prevention effect or even damage to components due to overheating can be reduced.

[0161] The pressure relief phase may include a pressure holding phase before the pressure relief phase, and a heat preservation phase may include a pressure relief phase after the pressure relief phase.

[0162] Specifically, when the cooking appliance 100 starts cooking, the heating device 13 heats the pot body 11, and then enters the pressure holding stage. When cooking is completed, the heating device 13 stops heating, the cooking appliance 100 enters the pressure relief stage, the exhaust device 50 exhausts air at a preset exhaust frequency P0, and at the same time the electric arc generating device discharges according to a preset program until the pressure in the cooking cavity 12 drops to normal pressure, then the electric arc generating device 31 can be controlled to stop working, and finally the heat preservation stage is entered.

[0163] The following is for reference. Figures 12-18 A method for controlling a cooking appliance 100 according to other embodiments of the present invention is described.

[0164] Reference Figure 1 According to an embodiment of the present invention, a cooking appliance 100 includes a cooking body 10 and a lid assembly 20. The cooking body 10 includes a pot body 11 and a heating device 12. The pot body 11 defines a cooking cavity 12 with an opening. The heating device 12 is used to heat the bottom of the pot body 11. The lid assembly 20 is movably disposed on the cooking body 10 and is used to open and close 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 engaged with the cooking body 10.

[0165] When the lid assembly 20 is opened, the user can put ingredients into the cooking cavity 12 or take out food through the opening of the cooking cavity 12. When the lid assembly 20 is closed, the lid assembly 20 and the pot body 11 together define a relatively closed cooking cavity 12, so that the ingredients can be cooked.

[0166] The cooking appliance 100 includes a plurality of bubble-breaking devices 30, and at least one bubble-breaking device 30 can be used to prevent overflow and break bubbles.

[0167] like Figure 12 As shown, the control method for the cooking appliance 100 includes:

[0168] S110: Obtain the cooking stage or cooking mode of the cooking appliance;

[0169] S220: Select and control one or more bubble-breaking devices to work according to the current cooking stage or cooking mode of the cooking appliance.

[0170] According to the embodiments of the present invention, the cooking appliance 100 can select and control one or more bubble-breaking devices 30 to work according to the current cooking stage or cooking mode of the cooking appliance 100. That is, it can select a suitable bubble-breaking device 30 to work. The bubble-breaking device 30 can be used to break bubbles and prevent overflow, meet the needs of different cooking stages or cooking modes, and improve the cooking effect and cooking efficiency of the cooking appliance. By adopting multiple bubble-breaking methods, the efficiency of bubble-breaking and overflow prevention can be greatly improved.

[0171] The cooking appliance 100 here can be a pressure cooker. The cooking stages of the pressure cooker may include heating stage, pressure holding stage and pressure release stage (or venting stage), etc. Depending on the current cooking stage or cooking mode of the pressure cooker, one or more bubble breaking devices 30 can be selected to work, thereby meeting the needs of different cooking stages.

[0172] Of course, the cooking appliance 100 can be a rice cooker. The cooking stages of the rice cooker can include heating, boiling, and keeping warm, etc. Depending on the current cooking stage or cooking mode of the rice cooker, one or more bubble-breaking devices 30 can be selected to work, thereby meeting the needs of different cooking stages.

[0173] Reference Figure 13 and Figure 14 According to some embodiments of the present invention, one of the bubble-breaking devices 30 is a kinetic energy bubble-breaking device, and the other is a thermal energy bubble-breaking device. The kinetic energy bubble-breaking device can disrupt the stability of the bubbles, achieving the effect of bubble breaking and preventing overflow. The thermal energy bubble-breaking device can cause the gas inside the bubble to expand rapidly upon heating, leading to a sudden increase in pressure inside the bubble, thereby achieving bubble breaking.

[0174] In some embodiments, the kinetic energy debubbling device includes a blower 32 disposed on the cover assembly 20 for driving air to flow toward the cooking cavity 12 to debubble.

[0175] 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.

[0176] 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.

[0177] In some embodiments, the thermal bubble-breaking device includes a heating element 33 disposed on the cover assembly 20 for heating the air above the cooking chamber 12 to break bubbles. The upper part of the cooking chamber 12 may include the upper space inside the cooking chamber 12, or it may include the space located above the cooking chamber 12.

[0178] 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.

[0179] For example, refer to Figure 12 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 13 The heating element 33 can be a film heating element 33, which can better achieve the effect of thermal energy defoaming by utilizing its rapid high temperature characteristics.

[0180] like Figure 15 As shown, in some embodiments, depending on the current cooking mode of the cooking appliance, one or more bubble-breaking devices are selected to operate, including:

[0181] S221: Determine the current cooking mode as the first cooking mode and control the heat energy debubbling device to work;

[0182] S222: Determine the current cooking mode as the second cooking mode and control the kinetic energy bubble breaking device to work.

[0183] For example, the thermal debubbling device includes a heating element 33, and in the first cooking mode, the heating temperature of the heating element 33 can be controlled to be greater than or equal to a preset heating temperature.

[0184] For example, the kinetic energy debubbling device includes a blower 32, and in the second cooking mode, the rotation speed of the blower 32 can be controlled to be greater than or equal to a preset rotation speed.

[0185] The following explanation uses the example of a first cooking mode being a meat cooking mode with a heat energy defoaming device including a heating element 33, and a second cooking mode being a rice cooking mode with a kinetic energy defoaming device including a blower element 32.

[0186] When the cooking appliance 100 is in meat cooking mode and enters the boiling stage, the bubbles contain a lot of protein, which can control the operation of the heating element 33. The heating element 33 heats the air in the upper part of the cooking chamber 12. When the extremely high temperature comes into contact with the bubbles, the gas inside the bubbles will expand rapidly due to the heat, resulting in a sudden increase in the pressure inside the bubbles, thereby breaking the bubbles. At the same time, the protein inside the bubbles will undergo the Maillard reaction due to the extremely high temperature, which will intensify the aroma of the meat and enhance its flavor.

[0187] After the boiling stage ends, the heating element 33 stops working, and the cooking appliance 100 enters the heat preservation stage or the cooking appliance 100 completes cooking. When the heating element 33 is working, its heating temperature can be controlled to be maintained at or above 130°C.

[0188] When the cooking appliance 100 is in the rice cooking mode and enters the boiling stage, the bubbles contain a lot of starch and have high viscosity. This allows the blower 32 to work. The blower 32 can drive air to flow into the cooking chamber 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.

[0189] After the boiling stage ends, the heating element 33 stops working, and the cooking appliance 100 enters the heat preservation stage or the cooking appliance 100 completes cooking. The blower 32 may include a fan, and when the fan is working, its speed can be controlled to be maintained at or above 1000 r / min.

[0190] Therefore, in the above technical solution, by selecting the operation of the thermal energy bubble-breaking device or the kinetic energy bubble-breaking device according to the current cooking mode of the cooking appliance 100, that is, selecting the appropriate bubble-breaking device 30 to operate, the bubble-breaking and overflow prevention requirements of different cooking modes can be met, which is conducive to improving the bubble-breaking efficiency and the overflow prevention effect, thereby improving the cooking effect and cooking efficiency of the cooking appliance.

[0191] like Figure 13 and Figure 14 As shown, in some embodiments, one bubble-breaking device 30 is a kinetic energy bubble-breaking device, and the other bubble-breaking device 30 is a thermal energy bubble-breaking device. The kinetic energy bubble-breaking device can disrupt the stability of the bubbles, achieving the effect of bubble breaking and preventing overflow. The thermal energy bubble-breaking device can cause the gas inside the bubble to expand rapidly upon heating, leading to a sudden increase in pressure inside the bubble, thereby achieving bubble breaking.

[0192] like Figure 16 As shown, in some embodiments, depending on the current cooking stage of the cooking appliance, one or more bubble-breaking devices are selected to operate, including:

[0193] S223: Determine the current cooking stage as the boiling stage, and control the kinetic energy debubbling device to work;

[0194] S224: Determine whether the current cooking stage is the venting or boiling stage, and control the operation of the thermal energy debubbling device.

[0195] For example, the thermal debubbling device includes a heating element 33, and the kinetic debubbling device includes a blower element 32. The boiling stage can be located before or after the exhaust or sudden boiling stage, and is not limited here.

[0196] Therefore, in the above technical solution, by selecting the operation of the thermal energy bubble-breaking device or the kinetic energy bubble-breaking device according to the current cooking stage of the cooking appliance 100, that is, selecting the appropriate bubble-breaking device 30 to operate, the bubble-breaking and overflow prevention requirements of different cooking stages can be met, which is conducive to improving the bubble-breaking efficiency and the overflow prevention effect, thereby improving the cooking effect and cooking efficiency of the cooking appliance.

[0197] In some embodiments, during the exhaust or boiling phase, the heating temperature of the thermal defoaming device is also detected; it is determined that the heating temperature of the thermal defoaming device is greater than or equal to a preset heating temperature, and the kinetic defoaming device and the thermal defoaming device are controlled to work simultaneously.

[0198] Specifically, when a user needs to cook using the cooking appliance 100, they can put the ingredients into the cooking cavity 12, start the corresponding cooking mode, and the heating device 13 will start heating the pot body 11.

[0199] The following explanation uses a thermal bubble-breaking device including a heating element 33 and a kinetic bubble-breaking device including a blower element 32 as examples. When the cooking appliance 100 enters the boiling stage, the blower element 32 can be controlled to operate. The blower element 32 can drive air to flow into the cooking chamber 12. The flowing air directly impacts the bubble walls, disrupting the stability of the bubbles, causing the bubble walls to deform, and ultimately the bubbles to burst. When the cooking appliance 100 enters the exhaust or sudden boiling stage, the heating element 33 can be controlled to operate. The heating element 33 heats the air in the upper part of the cooking chamber 12. 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 the pressure inside the bubbles, thereby achieving bubble breaking. During the venting or sudden boiling stage, the temperature detection device can monitor the heating temperature of the heating element 33. When the heating temperature of the heating element 33 is greater than or equal to the preset heating temperature (e.g., 130°C), which is insufficient to meet the bubble-breaking requirements, the blower 32 and the heating element 33 can be controlled to work together to achieve a multi-functional and powerful bubble-breaking and anti-overflow effect. While ensuring the bubble-breaking and anti-overflow effect, the problem of damage to the heating element 33 due to overheating can be reduced. After the venting or sudden boiling stage is completed, the blower 32 and the heating element 33 are controlled to stop working, and the cooking appliance 100 is controlled to enter other cooking stages until cooking is completed.

[0200] like Figure 17As shown, in some embodiments, at least one bubble-breaking device 30 includes an arc-generating device 31, which is disposed on the cover assembly 20 or the cooking body. The arc-generating device 31 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.

[0201] The electric arc generating device 31 produces an electric arc, accompanied by the generation of light and heat energy. The heat and light energy effectively reduce the surface tension of the bubble wall, accelerating its collapse. When extremely high temperatures come into contact with the bubble, the gas inside expands rapidly, causing a sudden increase in internal pressure, thus breaking the bubble. 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 its stability and causing deformation, ultimately leading to bubble collapse. The pressure wave effect generated by the interaction of the light energy from the electric arc generating device 31 with the bubble causes the bubble to collapse without affecting the original flavor of the cooked food.

[0202] like Figure 18 As shown, in some embodiments, depending on the current cooking stage of the cooking appliance, one or more bubble-breaking devices are selected to operate, including:

[0203] S225: Determine that the current cooking stage is the boiling stage, and control the electric arc generator to operate at the first power;

[0204] S226: Determine whether the current cooking stage is the venting or boiling stage, and control the electric arc generator to operate at a second power, which is greater than the first power.

[0205] Specifically, when a user needs to cook using the cooking appliance 100, they can put the ingredients into the cooking cavity 12, start the corresponding cooking mode, and the heating device 13 will start heating the pot body 11.

[0206] When the cooking appliance 100 enters the boiling stage, the electric arc generating device 31 can be controlled to work at the first power. 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 the extremely high temperature comes into contact with the bubble, the gas inside the bubble will expand rapidly due to the heat, resulting in a sudden increase in the 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 airflow, which directly impact the bubble wall, destroying the stability of the bubble, causing the bubble wall to deform, and finally the bubble ruptures.

[0207] When the cooking appliance 100 enters the venting or boiling stage, the electric arc generator 31 can be controlled to work at the second power to break the bubbles, achieving a multi-functional and super-strong bubble-breaking and anti-overflow effect.

[0208] After the venting or boiling stage is completed, the control arc generator 31 stops working, and the control cooking appliance 100 enters other cooking stages until cooking is completed.

[0209] Therefore, in the above technical solution, by selecting and controlling the electric arc generating device 31 to work at different power according to the current cooking stage of the cooking appliance 100, the bubble breaking and overflow prevention requirements of different cooking stages can be met, which is conducive to improving the bubble breaking efficiency and the overflow prevention effect, thereby improving the cooking effect and cooking efficiency of the cooking appliance.

[0210] In some embodiments, the control method further includes:

[0211] The cooking stage is defined as the heating stage; the heating device is controlled to operate, and the temperature of the cooking cavity is monitored.

[0212] Once the temperature of the cooking cavity is determined to be greater than or equal to the second preset temperature, the heating device is controlled to stop working.

[0235] Any process or method description in the flowchart or otherwise herein can be understood as representing a module, segment, or portion of code comprising one or more executable instructions for implementing custom logic functions or processes, and the scope of preferred embodiments of the invention includes additional implementations in which functions may be performed not in the order shown or discussed, including substantially simultaneously or in reverse order depending on the functions involved, as should be understood by those skilled in the art to which embodiments of the invention pertain.

[0236] The following describes a cooking appliance 100 according to an embodiment of the present invention, taken in conjunction with the accompanying drawings. The cooking appliance 100 may be a pressure cooker, rice cooker, or slow cooker, etc.

[0237] Reference Figure 1 and Figure 19 According to an embodiment of the present invention, a cooking appliance 100 includes a cooking body 10 and a lid assembly 20. The cooking body 10 includes a pot body 11 and a heating device 12. The pot body 11 defines a cooking cavity 12 with an opening. The heating device 12 is used to heat the bottom of the pot body 11. The lid assembly 20 is movably disposed on the cooking body 10 and is used to open and close the opening.

[0238] The cooking appliance 100 also includes a venting device 50, which can be located on the lid assembly 20 or the cooking body 10, for venting.

[0239] The cooking appliance 100 also includes a bubble-breaking device 30, at least one of 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 the arc-generating device 31 can generate a bubble-breaking arc in the upper part of the cooking cavity 12.

[0240] Therefore, by setting an electric arc generating device 31 on the lid assembly 20, and using the electric arc generating device 31 to generate a bubble-breaking electric arc in the upper part of the cooking chamber 12, the overflow prevention effect of the cooking appliance 100 can be improved, and large-area bubble breaking can be achieved. Through the high-efficiency bubble breaking and overflow prevention effect, it is ensured that the cooking appliance 100 will not overflow under intense and continuous boiling. The cooking appliance 100 does not need to reduce its operating power, and 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.

[0241] The cooking appliance 100 performs the control method of the cooking appliance 100 as described in any of the above embodiments. The cooking appliance 100 can control the start and stop of the bubble-breaking device 30 and the venting device 50 according to the current cooking stage.

[0242] According to the embodiments of the present invention, the cooking appliance 100 controls whether the bubble-breaking device 30 and the venting device 50 work according to the current cooking stage of the cooking appliance 100. The bubble-breaking device 30 can break bubbles and prevent overflow in a specific cooking stage, and the venting device 50 can vent air in a specific cooking stage, thereby meeting the needs of different cooking stages and improving the cooking effect and cooking efficiency of the cooking appliance 100.

[0243] Reference Figures 20-22 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.

[0244] 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.

[0245] Therefore, 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.

[0246] like Figures 20-22 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.

[0247] 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.

[0248] Reference Figure 21 and Figure 11 According 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.

[0249] 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.

[0250] 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.

[0251] Reference Figure 19 and Figure 20 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.

[0252] 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.

[0253] Reference Figure 20 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.

[0254] 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.

[0255] 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.

[0256] 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.

[0257] Reference Figure 20In 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.

[0258] 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.

[0259] 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.

[0260] Reference Figure 21 and Figure 22 According 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.

[0261] 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.

[0262] Reference Figure 22 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.

[0263] 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.

[0264] 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.

[0265] 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.

[0266] Reference Figure 21 and Figure 22 According to some embodiments of the present invention, 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 in the secondary coil 3112 performs 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.

[0267] 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.

[0268] 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.

[0269] 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.

[0270] 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.

[0271] Reference Figure 20 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.

[0272] 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.

[0273] Reference Figure 19 and Figure 23 According 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 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.

[0274] 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.

[0275] When cooking container 40 is required, refer to Figure 19 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 23 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. Here, the support member 41 can be an insulated support frame to reduce the contact between food and metal parts, which helps to ensure that the arc generating device 31 can discharge normally. Of course, the cooking container 40 can also be installed in the pot body 11 in other ways.

[0276] 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.

[0277] 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.

[0278] 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.

[0279] 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.

[0280] 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.

[0281] 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.

[0282] Other configurations and operations of the cooking utensil 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
