[0002] Traditional cooking appliances tend to overflow under intense and continuous boiling. Therefore, the cooking appliances need to actively sacrifice some of their operating power to prevent overflow.

[0043] 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.
[0044] Traditional cooking appliances tend to overflow under intense and continuous boiling. Therefore, the cooking appliances need to actively sacrifice some of their operating power to prevent overflow, resulting in less intense and continuous boiling during the cooking process, poor cooking effect, and longer cooking time.
[0045] To this end, this invention provides a cooking appliance 100 that uses an electric arc to break bubbles and prevent overflow during cooking, as well as a control method for the cooking appliance 100. The cooking appliance 100 can reliably activate the electric arc generating device 5 after the pot body 11 reaches a preset temperature, ensuring that the electric arc generating device 5 can reliably perform defoaming treatment and avoid overflow. The cooking appliance 100 can then operate continuously at high power.
[0046] The following is for reference. Figures 1-16 A control method for a cooking appliance 100 according to an embodiment of the present invention is described. The cooking appliance 100 may be a pressure cooker or a rice cooker, etc.
[0047] According to an embodiment of the present invention, a cooking appliance 100 includes: a cooking body 1, a lid assembly 3, and an electric arc generating device 5.
[0048] Combination Figures 8-10 The cooking body 1 includes a pot body 11 and a heating device 12. The pot body 11 defines a cooking cavity 110 with an opening 1101. The heating device 12 is used to heat the pot body 11. Food is heated by the heating device 12 in the cooking cavity 110 defined by the pot body 11, thereby realizing heating and cooking. The user puts food into the cooking cavity 110 through the opening 1101. After the food boils, the boiling bubbles generated also overflow outward through the opening 1101 of the cooking cavity 110.
[0049] The lid assembly 3 is used to open and close the opening 1101. When the lid assembly 3 opens the opening 1101, the user can put food into the cooking cavity 110 through the opening 1101. When the lid assembly 3 closes the opening 1101, the lid assembly 3 and the pot body 11 together define a closed cooking cavity 110. The lid assembly 3 can be rotatably connected to the cooking body 1, so that the lid assembly 3 can rotate between the open opening 1101 position and the closed opening 1101 position; the lid assembly 3 can be detachably engaged with the cooking body 1.
[0050] An arc generating device 5 is disposed on the cooking body 1 or the cover assembly 3, and includes a discharge section 51 for generating a debubbling arc in the upper part of the cooking cavity 110. The upper part of the cooking cavity 110 may include the upper space within the cooking cavity 110, or it may include the space located above the cooking cavity 110. The discharge section 51 is used to generate a debubbling arc within the cooking cavity 110, and the arc generating device 5 achieves debubbling by generating a debubbling arc at the discharge section 51.
[0051] During the cooking process, the food inside the cooking cavity 110 is continuously heated and produces 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 3. This will not only cause dirt on the cooking surface, but also cause moisture loss inside the cooking cavity 110, affecting the cooking effect of the food.
[0052] The arc generating device 5 for debubbling in this application achieves debubbling by generating a debubbling arc at the discharge section 51.
[0053] The electric arc generator 5 produces an electric arc, along with light and heat energy. The electric arc and light energy effectively reduce the surface tension of the bubble wall, accelerating its rupture. When the extremely high temperature comes into contact with the bubble, the gas inside expands rapidly, causing a sudden increase in pressure and thus breaking the bubble.
[0054] Furthermore, under certain conditions, during the formation of the electric arc, the plasma expands at high speed, forming shock waves and directional airflows that directly impact the bubble wall, disrupting the bubble's stability, causing the bubble wall to deform, and ultimately leading to the bubble's rupture.
[0055] The electric arc degassing method, with its concentrated and high-intensity energy, directly targets the bubbles generated after boiling, causing them to break rapidly. Compared to mechanical degassing wheels or blowers, electric arc degassing can process more bubbles in a shorter time, improving degassing efficiency. Because electric arc degassing acts directly on the bubbles through energy conversion without physical contact, it leaves no rice water or other residues inside the equipment. This reduces cleaning difficulty and avoids hygiene problems caused by mold growth from residues.
[0056] The heat generated by the electric arc discharge is released into the pot body 11, which can assist in heating food and reduce overall energy consumption. Compared with the noise of the blower bubble breaking device, the electric arc bubble breaking only produces a slight ionization sound, improving the user experience. The electric arc bubble breaking also avoids direct contact between the device and the bubbles, reducing the difficulty of cleaning.
[0057] Arc degassing technology is not limited by factors such as the heating power of the rice cooker or the viscosity of the food, and can maintain a stable degassing effect under various cooking conditions. Whether cooking rice, porridge, or even ingredients that are prone to burning, it can effectively prevent foam from overflowing. Arc degassing technology can complete the degassing process in a short time and also reduces the safety hazards caused by prolonged high-temperature operation.
[0058] In summary, using an electric arc to break bubbles and prevent overflow not only improves the efficiency of bubble breaking and reduces residues, but also has strong adaptability and high safety.
[0059] The electric arc generated by the electric arc generating device 5 of this application can efficiently break the bubbles generated by the boiling of food in the cooking chamber 110. The bubble breaking efficiency is high, so there is no need to sacrifice operating power to prevent overflow. The cooking appliance 100 can operate at high power in the boiling state, ensuring the cooking efficiency and cooking effect of food.
[0060] Furthermore, such as Figure 1 As shown, the method for controlling the cooking appliance 100 includes the following steps:
[0061] S1. During the cooking process of the cooking appliance, detect the temperature of the pot body;
[0062] The temperature of the pot body 11 can be the temperature of the pot body 11 itself, the temperature inside the cooking cavity 110, or the temperature above the cooking cavity 110. Different cooking stages of the cooking appliance 100 result in different temperature changes within the cooking cavity 110. Since the temperature inside the cooking cavity 110 determines whether the food inside the cooking cavity 110 boils and produces bubbles, during the cooking process of the cooking appliance 100, as the temperature gradually increases during the heating process, the temperature of the pot body 11 is detected, and it is determined whether the temperature of the food has reached near the boiling point. Once the temperature of the food reaches near the boiling point, the food is then subjected to bubble-breaking treatment.
[0063] S2. Determine that the temperature of the pot body has reached the preset temperature, and control the arc generating device to work.
[0064] Specifically, when the temperature of the pot body 11 reaches the preset temperature value, it can be deduced that the temperature of the food inside the cooking cavity 110 rises to near the boiling point. The food will then generate a large number of bubbles during boiling. At this point, it is necessary to control the operation of the electric arc generator 5 to utilize the bubble-breaking arc generated by the electric arc generator 5 to break the bubbles generated after the food boils. This prevents overflow caused by a large number of bubbles generated during continuous high-power operation of the cooking appliance 100, thus improving the user experience.
[0065] Once the temperature of the pot body 11 reaches the preset temperature, the electric arc generator 5 is controlled to work. On the one hand, this avoids the waste of electricity caused by the electric arc generator 5 running continuously before the food boils. On the other hand, it ensures that the electric arc generator 5 can be stably started to break bubbles before and after the food boils, reliably eliminating the bubbles generated after the food boils, avoiding the phenomenon of overflowing bubbles during operation, and improving the user experience of the cooking appliance 100.
[0066] According to the control method of the cooking appliance 100 of the present invention, the electric arc generating device 5 inside the cooking appliance 100 is controlled by the temperature of the pot body 11, and the electric arc generating device 5 is turned on after the cooking temperature reaches the preset temperature, which ensures that the electric arc generating device 5 can reliably perform defoaming treatment, avoids overflowing, and improves the user experience of the cooking appliance 100.
[0067] In some embodiments, the cooking appliance 100 can be a rice cooker. During the cooking process, there is airflow between the cooking cavity 110 and the outside. Once the food in the cooking cavity 110 boils, there is a risk of overflow.
[0068] In other embodiments, the cooking appliance 100 can be a pressure cooker. During the pressure cooking process, the cooking chamber 110 is kept in a high-pressure sealed state, and there is no risk of overflow during the pressure cooking process. During the venting stage of the pressure cooker cooking process, the cooking chamber 110 is allowed to circulate with the outside air, and there is a risk of overflow during this process.
[0069] According to some embodiments of the present invention, with reference to Figure 2 When the cooking appliance is a rice cooker (100), the control methods also include:
[0070] S11: Query the preset table to obtain the preset temperature based on the atmospheric pressure of the rice cooker's location.
[0071] In practice, the rice cooker is equipped with a pressure detection device 9 that can detect the local atmospheric pressure value in real time. Through a preset atmospheric pressure and temperature conversion table, the system can automatically convert the detected atmospheric pressure parameters into a preset temperature value that is suitable for the current geographical environment.
[0072] The principle behind the construction of the atmospheric pressure query preset table is based on the correlation of physical characteristics: atmospheric pressure values directly affect the boiling point (T) of liquids in the region where cooking appliance 100 is located, while preset temperature parameters are dynamically correlated with boiling point values.
[0073] In some embodiments, the preset temperature is T-10℃ to T+20℃, where T is the boiling point of the region where the cooking appliance 100 is located.
[0074] In other words, after the pressure detection device 9 detects the atmospheric pressure in the area where the rice cooker is located, the preset temperature can be obtained by querying the preset table based on the atmospheric pressure. The preset temperature obtained must not be greater than the boiling point T+20℃ of the liquid in the cooking appliance 100 in the area where the cooking appliance 100 is located, and must not be less than the boiling point T-10℃ of the liquid in the cooking appliance 100 in the area where the cooking appliance 100 is located.
[0075] Therefore, the cooking appliance 100 can be used in regions with different altitudes. In high-altitude regions, the boiling point of liquids is lower, and the preset temperature is also lower. This avoids the overflow phenomenon caused by the electric arc generating device 5 not being able to break the bubbles in time after the food boils and produces bubbles in high-altitude regions, because the temperature of the pot body 11 has not reached the preset temperature.
[0076] In some embodiments, after the pressure detection device 9 acquires the current atmospheric pressure parameter, the control system automatically matches the corresponding boiling point reference value T and generates precise temperature parameters that satisfy the upper limit of T+20℃ and the lower limit of T-10℃. This dynamic temperature adjustment mechanism enables the cooking appliance 100 to intelligently adapt to different altitude environments: in high-altitude areas, the system automatically lowers the preset temperature parameter to ensure that a reasonable upper limit of T+20℃ is maintained even after the actual boiling point (T) of the liquid decreases, thereby effectively solving the problem of temperature control lag caused by changes in atmospheric pressure. Through this technical solution, the risk of overflow caused by the untimely response of the arc generating device 5 due to boiling delay in high-altitude areas is avoided, while ensuring the efficient cooking needs in low-altitude areas, significantly improving the environmental adaptability and safety of the product.
[0077] According to some embodiments of the present invention, with reference to Figure 3 When the cooking appliance is a pressure cooker (100), the control method also includes:
[0078] S12, the pressure cooker is in the venting stage;
[0079] Specifically, the pressure cooker operates through a high-pressure sealing cooking stage and a pressure-reducing venting stage. During the high-pressure cooking stage, the entire pressure cooker is sealed to maintain a high-pressure state within the cooking chamber 110. In this stage, because the cooking chamber 110 is sealed and the fluid within it is in a supercritical state, surface tension changes inhibit bubble formation, eliminating the risk of overflow. Therefore, the pressure cooker does not require arc degassing. During the venting stage, the pressure cooker's vent 31 is open, allowing gas and some bubbles within the cooking chamber 110 to escape. This presents a risk of overflow, necessitating degassing to prevent it.
[0080] S21, Determine that the temperature of the pot body has reached the preset temperature, and control the arc generating device to work;
[0081] When the pressure cooker is in the venting stage, it is also necessary to judge the temperature inside the pressure cooker and control the operation of the electric arc generating device 5 according to the temperature of the pot body 11.
[0082] In some embodiments, after the pressure cooker is in the venting stage, the temperature of the pot body 11 is detected. When the temperature of the pot body 11 reaches the preset temperature, the arc generating device 5 is controlled to operate. When the temperature inside the pot body 11 has not reached the preset temperature, the arc generating device 5 does not need to operate, thus avoiding waste of electrical energy.
[0083] During the exhaust phase, the exhaust temperature of the cooking cavity 110 is T0. A preset temperature is set based on the exhaust temperature. The preset temperature is not greater than T0+10℃ and not less than T0-20℃.
[0084] In some embodiments, when the pressure cooker enters the venting stage, the control system automatically matches the temperature T0 within the corresponding cooking cavity 110 and generates precise temperature parameters that satisfy the upper limit of T0+10℃ and the lower limit of T0-20℃. This dynamic temperature adjustment mechanism enables the cooking appliance 100 to intelligently adapt to different venting temperatures: when the venting temperature is low, the system automatically lowers the preset temperature parameters to ensure that a reasonable upper limit of T+10℃ is maintained even after the venting temperature decreases, thereby effectively solving the problem of temperature control lag caused by different venting temperatures. This technical solution avoids the risk of overflow caused by the untimely response of the arc generating device 5 due to boiling delay during high-pressure venting, while also ensuring the bubble-breaking requirements during low-pressure venting, significantly improving the user experience.
[0085] In order to more reliably avoid the phenomenon of overflowing bubbles during cooking, when the effect of the electric arc breaking the bubble is insufficient to completely prevent the bubbles from overflowing during the operation of the electric arc generating device 5, it is necessary to reduce the generation of bubbles by controlling the heating power of the heating device 12 of the cooking appliance 100.
[0086] Specifically, refer to Figure 4The control methods also include:
[0087] S301, during the operation of the electric arc generating device, also detects the height of bubbles inside the pot;
[0088] During the operation of the electric arc generating device 5, the liquid in the cooking chamber 110 is in a boiling state, which will continuously generate bubbles. The generated bubbles are broken after being processed by the electric arc generating device 5, and the bubble height in the pot body 11 will be maintained within a certain range.
[0089] In some embodiments, an anti-overflow electrode can be used to detect the height of bubbles in the pot 11. When a bubble rises and contacts the anti-overflow electrode, the circuit between the anti-overflow electrodes will be connected to a certain extent because the bubble contains conductive substances such as water vapor. Even if the current intensity in the circuit changes, it can be determined whether the bubble has reached the position of the anti-overflow electrode based on the change in current, thereby indirectly detecting the height of bubbles in the pot 11.
[0090] In other embodiments, a capacitive sensor can be used to detect the height of bubbles inside the pot 11. When bubbles are generated and rise inside the pot 11, the capacitance value of the capacitive sensor changes, thereby detecting the height of bubbles inside the pot 11 based on the change in capacitance value.
[0091] Of course, pressure sensors, cameras, and other devices can also be used to detect the height of air bubbles inside the pot 11.
[0092] S302, determine that the height of the bubbles inside the pot is less than the preset height, and control the heating device to heat at the first power;
[0093] The first power can be an ultra-high power that is not safe. In the initial stage of the operation of the electric arc generating device 5, since the food in the cooking chamber 110 has just started to boil, the amount of bubbles generated is small. The electric arc generating device 5 can promptly break the generated bubbles, and the bubble height in the pot body 11 will be maintained below the preset height. There is no risk of overflow. The heating device 12 can continue to operate at high power without sacrificing heating power. The food can be continuously cooked at high temperature, which improves the cooking efficiency of the food and makes the cooked food more delicious.
[0094] S303, if the height of the bubbles in the pot is determined to be greater than or equal to the preset height, control the heating device to reduce the power and heat with a second power, which is less than the first power.
[0095] The second power can be a safe power. As the heating device 12 continues to operate at high power, the temperature of the pot body 11 gradually rises. The food in the cooking cavity 110 generates more bubbles under high temperature. When the bubble generation speed is higher than the bubble breaking speed of the arc generator 5, the bubble height in the pot body 11 will increase. When the bubble height in the pot body 11 is greater than or equal to the preset height, the cooking appliance 100 is at risk of overflow. The cooking cavity 110 is equipped with a bubble height detection device 7 to detect the bubble height in the pot body 11. When the bubble height detection device 7 detects that the bubble height in the pot body 11 is greater than or equal to the preset height, the heating device 12 can be controlled to reduce the power and heat with a second power lower than the first power to reduce the rate at which the food generates bubbles, reduce the bubble height in the pot body 11, and avoid overflow.
[0096] According to some embodiments of the present invention, such as Figure 5 As shown, the control method also includes:
[0097] S101, during the cooking process of the cooking appliance, if the temperature of the pot body is determined to be lower than the preset temperature, the heating device is controlled to work at the first power.
[0098] The first power is less than or equal to the maximum power of the heating device 12.
[0099] In other words, during the cooking process of the cooking appliance 100, the heating device 12 initially operates at high power to ensure cooking efficiency. Under the heating effect of the heating device 12, the temperature of the pot body 11 rises rapidly until it reaches the preset temperature. After the temperature of the pot body 11 reaches the preset temperature, the liquid in the cooking cavity 110 gradually boils and generates bubbles. The electric arc generating device 5 is then activated to break the generated bubbles. Since the bubble-breaking efficiency of the electric arc generating device 5 is greater than the rate at which the liquid in the cooking cavity 110 generates bubbles, the bubble height in the pot body 11 will be in dynamic equilibrium and lower than the preset height. There is no risk of overflow in the cooking appliance 100, and the heating device 12 continues to operate at high power.
[0100] Under the continuous high-power operation of the heating device 12, the speed at which the liquid in the cooking cavity 110 boils and generates bubbles gradually increases until the electric arc generating device 5 is unable to break all the bubbles in time. The height of the bubbles in the pot body 11 rises. When the bubble height detection device 7 in the cooking cavity 110 detects that the bubble height in the pot body 11 is greater than or equal to the preset height, it controls the heating device 12 to reduce the power and heat with a second power that is less than the first power to reduce the speed at which the food generates bubbles, reduce the bubble height in the pot body 11, and avoid overflow.
[0101] According to other embodiments of the present invention, such as Figure 6As shown, during the cooking process of cooking appliance 100,
[0102] S102, determine that the temperature of the pot body is lower than the preset temperature, and control the heating device to heat at the third power;
[0103] S201, determine that the temperature of the pot body has reached the preset temperature, and control the heating device to work at a first power, a third power greater than the first power, and the third power less than or equal to the maximum power of the heating device.
[0104] In other words, during the cooking process of the cooking appliance 100, the heating device 12 initially operates at its maximum power (third power) to ensure cooking efficiency. Under the heating effect of the heating device 12, the temperature of the pot body 11 rises rapidly until it reaches the preset temperature. After the temperature of the pot body 11 reaches the preset temperature, the liquid in the cooking chamber 110 gradually boils and generates bubbles. The electric arc generating device 5 is then activated to break the generated bubbles, and the heating power of the heating device 12 is simultaneously reduced. The heating device 12 then operates at a medium-high power (first power) to reduce the rate of bubble generation while ensuring cooking efficiency. At this time, because the bubble-breaking efficiency of the electric arc generating device 5 is greater than the rate at which the liquid in the cooking chamber 110 generates bubbles, the bubble height in the pot body 11 will be in dynamic equilibrium and lower than the preset height. Therefore, there is no risk of overflow in the cooking appliance 100, and the heating device 12 can operate at a medium-high power (first power).
[0105] As the heating device 12 continues to operate at medium-high power with the first power, the speed at which the liquid in the cooking cavity 110 boils and generates bubbles gradually increases until the electric arc generating device 5 is unable to break all the bubbles in time. The height of the bubbles in the pot body 11 rises. When the bubble height detection device 7 in the cooking cavity 110 detects that the bubble height in the pot body 11 is greater than or equal to the preset height, it controls the heating device 12 to reduce the power and heat with a second power that is less than the first power to further reduce the speed at which the food generates bubbles, reduce the bubble height in the pot body 11, and prevent overflow.
[0106] According to some embodiments of the present invention, during the operation of the arc generating device 5, the open / closed state of the cover assembly 3 is also detected;
[0107] Once the cover assembly 3 is confirmed to be in the open state, the arc generating device 5 is controlled to stop working.
[0108] In some cases, during cooking with the cooking appliance 100, the user may open the lid assembly 3 of the cooking appliance 100 after the pot body 11 reaches the preset temperature to observe the cooking process or skim off any foam. Therefore, during the operation of the arc generating device 5, if... Figure 7 As shown, the control method also includes:
[0109] S31. During the operation of the electric arc generating device, the opening and closing status of the cover assembly is also detected.
[0110] S32. Ensure the cover assembly is in the open state and control the arc generator to stop working.
[0111] In other words, during the operation of the arc generating device 5, the arc generating device 5 will stop working after the cover assembly 3 is opened. This avoids the energy waste caused by the continuous operation of the arc generating device 5 when the cover is open, and provides precise power supply only when the cover is closed, eliminating ineffective energy consumption when the cover is open, extending the equipment life, and also preventing human injury from contact with the operating arc generating device 5.
[0112] After the user finishes opening the lid, it should be closed again. After the lid is closed, the temperature of the pot body 11 of the cooking appliance 100 is still higher than the preset temperature. The electric arc generating device 5 should continue to work after the lid is closed to ensure that the electric arc generating device 5 works in time to defoam the food in the cooking cavity 110 in time, so as to avoid the bubbles from overflowing, affecting the user experience, causing liquid loss, and affecting the flavor of the food after cooking.
[0113] According to a second aspect embodiment of the present invention, a readable storage medium is stored thereon having a cooking control program that, when executed by a processor, implements the control method of the cooking appliance 100 as described above.
[0114] According to an embodiment of the present invention, a readable storage medium stores a control program for a cooking appliance 100 thereon, which, when executed by a processor, implements the control method for the cooking appliance 100 as described in the above embodiment.
[0115] It should be noted that examples of readable storage media may include, but are not limited to, phase-change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory, or other optical and magnetic storage media, which will not be elaborated here.
[0116] The readable storage medium provided in the above embodiments of this application and the control method of the cooking appliance 100 provided in the embodiments of this application are based on the same inventive concept and have the same beneficial effects as the methods adopted, run or implemented by the application stored therein.
[0117] The following describes a cooking appliance 100 according to some embodiments of the present invention.
[0118] According to an embodiment of the present invention, a cooking appliance 100 includes a memory, a processor, and a control program for the cooking appliance 100 stored in the memory and executable on the processor. When the processor executes the control program, it implements the control method for the cooking appliance 100 as described in the above embodiment.
[0119] The cooking appliance 100 provided in this application embodiment and the control method of the cooking appliance 100 provided in this application embodiment are based on the same inventive concept and have the same beneficial effects as the methods used, operated or implemented.
[0120] The following is for reference. Figures 8-16 A cooking appliance 100 according to an embodiment of the present invention is described. The cooking appliance 100 may be a pressure cooker or a rice cooker, etc.
[0121] According to an embodiment of the present invention, a cooking appliance 100 includes: a cooking body 1, a lid assembly 3, and an electric arc generating device 5.
[0122] The cooking body 1 includes a pot body 11 and a heating device 12. The pot body 11 defines a cooking cavity 110 with an opening 1101. The heating device 12 is used to heat the pot body 11. Food is heated by the heating device 12 in the cooking cavity 110 defined by the pot body 11, thereby realizing heating and cooking. The user puts food into the cooking cavity 110 through the opening 1101. After the food boils, the boiling bubbles generated also overflow outward through the opening 1101 of the cooking cavity 110.
[0123] The lid assembly 3 is used to open and close the opening 1101. When the lid assembly 3 opens the opening 1101, the user can put food into the cooking cavity 110 through the opening 1101. When the lid assembly 3 closes the opening 1101, the lid assembly 3 and the pot body 11 together define a closed cooking cavity 110.
[0124] An arc generating device 5 is disposed on the cooking body 1 or the cover assembly 3, and includes a discharge section 51 for generating a debubbling arc in the upper part of the cooking cavity 110. The upper part of the cooking cavity 110 may include the upper space within the cooking cavity 110, or it may include the space located above the cooking cavity 110. The discharge section 51 is used to generate a debubbling arc within the cooking cavity 110, and the arc generating device 5 achieves debubbling by generating a debubbling arc at the discharge section 51.
[0125] During the cooking process, the food inside the cooking cavity 110 is continuously heated and produces 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 3. This will not only cause dirt on the cooking surface, but also cause moisture loss inside the cooking cavity 110, affecting the cooking effect of the food.
[0126] The arc generating device 5 of this application achieves bubble breaking by generating a bubble-breaking arc at the discharge section 51.
[0127] The electric arc generator 5 produces an electric arc, along with light and heat energy. The electric arc and light energy effectively reduce the surface tension of the bubble wall, accelerating its rupture. When the extremely high temperature comes into contact with the bubble, the gas inside expands rapidly, causing a sudden increase in pressure and thus breaking the bubble.
[0128] Furthermore, under certain conditions, during the formation of the electric arc, the plasma expands at high speed, forming shock waves and directional airflows that directly impact the bubble wall, disrupting the bubble's stability, causing the bubble wall to deform, and ultimately leading to the bubble's rupture.
[0129] The electric arc degassing method, with its concentrated and high-intensity energy, directly targets the bubbles generated after boiling, causing them to break rapidly. Compared to mechanical degassing wheels or blowers, electric arc degassing can process more bubbles in a shorter time, improving degassing efficiency. Because electric arc degassing acts directly on the bubbles through energy conversion without physical contact, it leaves no rice water or other residues inside the equipment. This reduces cleaning difficulty and avoids hygiene problems caused by mold growth from residues.
[0130] The heat generated by the electric arc discharge is released into the pot body 11, which can assist in heating food and reduce overall energy consumption. Compared with the noise of the blower bubble breaking device, the electric arc bubble breaking only produces a slight ionization sound, improving the user experience. The electric arc bubble breaking also avoids direct contact between the device and the bubbles, reducing the difficulty of cleaning.
[0131] Arc degassing technology is not limited by factors such as the heating power of the rice cooker or the viscosity of the food, and can maintain a stable degassing effect under various cooking conditions. Whether cooking rice, porridge, or even ingredients that are prone to burning, it can effectively prevent foam from overflowing. Arc degassing technology can complete the degassing process in a short time and also reduces the safety hazards caused by prolonged high-temperature operation.
[0132] In summary, using an electric arc to break bubbles and prevent overflow not only improves the efficiency of bubble breaking and reduces residues, but also has strong adaptability and high safety.
[0133] The electric arc generated by the electric arc generating device 5 of this application can efficiently break the bubbles generated by the boiling of food in the cooking chamber 110. The bubble breaking efficiency is high, so there is no need to sacrifice operating power to prevent overflow. The cooking appliance 100 can operate at high power in the boiling state, ensuring the cooking efficiency and cooking effect of food.
[0134] The cooking appliance 100 also includes a temperature detection device 8 and a control device 6. The temperature detection device 8 is used to detect the temperature of the pot body 11. The control device 6 acquires the temperature of the pot body 11 detected by the temperature detection device 8 and controls the operation of the cooking appliance 100 according to the acquired temperature of the pot body 11. The control device 6 can control whether the electric arc generating device 5 starts to work according to the temperature of the pot body 11. When the temperature detection device 8 detects that the temperature of the pot body 11 has reached the preset temperature, the control device 6 controls the electric arc generating device 5 to work.
[0135] In this process, different cooking stages of the cooking appliance 100 result in different temperature changes within the cooking cavity 110. Since the temperature of the pot body 11 determines whether the food in the cooking cavity 110 boils and produces bubbles, during the cooking process of the cooking appliance 100, as the temperature gradually increases, the temperature of the pot body 11 is detected, and it is determined whether the temperature of the food has reached near the boiling point. Once the temperature of the food reaches near the boiling point, the food is then subjected to bubble-breaking treatment.
[0136] Specifically, when the temperature detection device 8 detects that the temperature of the pot body 11 has reached the preset temperature value, it can deduce that the temperature of the food inside the cooking cavity 110 has risen to near the boiling point, and the food will generate a large number of bubbles under boiling action. The control device 6 obtains this information and controls the electric arc generator 5 to work, so as to use the bubble-breaking electric arc generated by the operation of the electric arc generator 5 to break the bubbles generated after the food boils, so as to avoid the overflow caused by a large number of bubbles generated under the continuous high power operation of the cooking appliance 100, and improve the user experience.
[0137] Once the temperature of the pot body 11 reaches the preset temperature, the electric arc generator 5 is controlled to work. On the one hand, this avoids the waste of electricity caused by the electric arc generator 5 running continuously before the food boils. On the other hand, it ensures that the electric arc generator 5 can be stably started to break bubbles before and after the food boils, reliably eliminating the bubbles generated after the food boils, avoiding the phenomenon of overflowing bubbles during operation, and improving the user experience of the cooking appliance 100.
[0138] In some embodiments, the cooking appliance 100 can be a rice cooker. During the cooking process, there is airflow between the cooking cavity 110 and the outside. Once the food in the cooking cavity 110 boils, there is a risk of overflow.
[0139] In other embodiments, the cooking appliance 100 can be a pressure cooker. During the pressure cooking process, the cooking chamber 110 is kept in a high-pressure sealed state, and there is no risk of overflow during the pressure cooking process. During the venting stage of the pressure cooker cooking process, the cooking chamber 110 is allowed to circulate with the outside air, and there is a risk of overflow during this process.
[0140] According to some embodiments of the present invention, the cooking appliance 100 is a rice cooker, and the rice cooker further includes a pressure detection device 9 and a acquisition device 10.
[0141] The pressure detection device 9 is used to detect the atmospheric pressure in the area where the rice cooker is located. The acquisition device 10 acquires the atmospheric pressure value detected by the pressure detection device 9, and retrieves the preset temperature from a preset table based on the atmospheric pressure value detected by the pressure detection device 9. The preset temperature information is then transmitted to the control device 6, which controls the operation of the cooking appliance 100 based on the preset temperature value.
[0142] In practice, the rice cooker is equipped with a pressure detection device 9 that can detect the local atmospheric pressure value in real time. Through a preset atmospheric pressure and temperature conversion table, the system can automatically convert the detected atmospheric pressure parameters into a preset temperature value that is suitable for the current geographical environment.
[0143] The principle behind the construction of the atmospheric pressure query preset table is based on the correlation of physical characteristics: atmospheric pressure values directly affect the boiling point (T) of liquids in the region where cooking appliance 100 is located, while preset temperature parameters are dynamically correlated with boiling point values.
[0144] According to some embodiments of the present invention, the preset temperature is T-10℃ to T+20℃; T is the boiling point of the region where the rice cooker is located.
[0145] In other words, after the pressure detection device 9 detects the atmospheric pressure in the area where the rice cooker is located, the acquisition device 10 can obtain the preset temperature by querying a preset table based on the atmospheric pressure. The obtained preset temperature must not be greater than the boiling point T+20℃ of the liquid in the cooking appliance 100 in the area where the cooking appliance 100 is located, and must not be less than the boiling point T-10℃ of the liquid in the cooking appliance 100 in the area where the cooking appliance 100 is located.
[0146] Therefore, the cooking appliance 100 can be used in regions with different altitudes. In high-altitude regions, the boiling point of liquids is lower, and the preset temperature is also lower. This avoids the overflow phenomenon caused by the electric arc generating device 5 not being able to break the bubbles in time after the food boils and produces bubbles in high-altitude regions, because the temperature of the pot body 11 has not reached the preset temperature.
[0147] In some embodiments, after the pressure detection device 9 acquires the current atmospheric pressure parameter, the control system automatically matches the corresponding boiling point reference value T and generates precise temperature parameters that satisfy the upper limit of T+20℃ and the lower limit of T-10℃. This dynamic temperature adjustment mechanism enables the cooking appliance 100 to intelligently adapt to different altitude environments: in high-altitude areas, the system automatically lowers the preset temperature parameter to ensure that a reasonable upper limit of T+20℃ is maintained even after the actual boiling point (T) of the liquid decreases, thereby effectively solving the problem of temperature control lag caused by changes in atmospheric pressure. Through this technical solution, the risk of overflow caused by the untimely response of the arc generating device 5 due to boiling delay in high-altitude areas is avoided, while ensuring the efficient cooking needs in low-altitude areas, significantly improving the environmental adaptability and safety of the product.
[0148] According to some embodiments of the present invention, the cooking appliance 100 is a pressure cooker. When the pressure cooker enters the venting stage and the temperature detection device 8 detects that the temperature of the pot body 11 has reached the preset temperature, the control device 6 controls the electric arc generating device 5 to work.
[0149] Specifically, the pressure cooker operates through a high-pressure sealing cooking stage and a pressure-reducing venting stage. During the high-pressure cooking stage, the entire pressure cooker is sealed to maintain a high-pressure state within the cooking chamber 110. In this stage, because the cooking chamber 110 is sealed and the fluid within it is in a supercritical state, surface tension changes inhibit bubble formation, eliminating the risk of overflow. Therefore, the pressure cooker does not require arc degassing. During the venting stage, the pressure cooker's vent 31 is open, allowing gas and some bubbles within the cooking chamber 110 to escape. This presents a risk of overflow, necessitating degassing to prevent it.
[0150] When the pressure cooker is in the venting stage, it is also necessary to judge the temperature inside the pressure cooker and control the operation of the electric arc generating device 5 according to the temperature of the pot body 11.
[0151] In some embodiments, after the pressure cooker is in the venting stage, the temperature of the pot body 11 is detected. When the temperature of the pot body 11 reaches the preset temperature, the arc generating device 5 is controlled to operate. When the temperature inside the pot body 11 has not reached the preset temperature, the arc generating device 5 does not need to operate, thus avoiding waste of electrical energy.
[0152] During the exhaust phase, the temperature inside the cooking cavity 110 is T0, with a preset temperature of T0-20℃ to T0+10℃.
[0153] In some embodiments, when the pressure cooker enters the venting stage, the control system automatically matches the temperature T0 within the corresponding cooking cavity 110 and generates precise temperature parameters that satisfy the upper limit of T0+10℃ and the lower limit of T0-20℃. This dynamic temperature adjustment mechanism enables the cooking appliance 100 to intelligently adapt to different venting temperatures: when the venting temperature is low, the system automatically lowers the preset temperature parameters to ensure that a reasonable upper limit of T+10℃ is maintained even after the venting temperature decreases, thereby effectively solving the problem of temperature control lag caused by different venting temperatures. This technical solution avoids the risk of overflow caused by the untimely response of the arc generating device 5 due to boiling delay during high-pressure venting, while also ensuring the bubble-breaking requirements during low-pressure venting, significantly improving the user experience.
[0154] like Figure 8 , Figure 9 and Figure 16 As shown, the cooking appliance 100 also includes: a bubble height detection device 7, which is used to detect the bubble height inside the pot body 11. When the bubble height detection device 7 detects that the bubble height inside the pot body 11 is less than a preset height, the control device 6 controls the heating device 12 to heat at a first power. When the bubble height detection device 7 detects that the bubble height inside the pot body 11 is greater than or equal to the preset height, the control device 6 controls the heating device 12 to reduce its power and heat at a second power, which is less than the first power.
[0155] During the operation of the electric arc generating device 5, the liquid in the cooking chamber 110 is in a boiling state, which will continuously generate bubbles. The generated bubbles are broken after being processed by the electric arc generating device 5, and the bubble height in the pot body 11 will be maintained within a certain range.
[0156] In the initial stage of operation of the electric arc generator 5, since the food in the cooking chamber 110 has just started to boil, the amount of bubbles generated is small. The electric arc generator 5 can promptly break the generated bubbles, and the bubble height in the pot body 11 will be maintained below the preset height, eliminating the risk of overflow. The heating device 12 can operate at high power continuously without sacrificing heating power, and the food can be cooked at high temperature continuously, improving the cooking efficiency and making the cooked food more delicious.
[0157] As the heating device 12 continues to operate at high power, the temperature of the pot body 11 gradually rises. Under the action of high temperature, the food in the cooking cavity 110 generates more bubbles. When the bubble generation speed is higher than the bubble breaking speed of the arc generator 5, the bubble height in the pot body 11 will increase. When the bubble height in the pot body 11 is greater than or equal to the preset height, the cooking appliance 100 is at risk of overflow. The cooking cavity 110 is equipped with a bubble height detection device 7 to detect the bubble height in the pot body 11. When the bubble height detection device 7 detects that the bubble height in the pot body 11 is greater than or equal to the preset height, the heating device 12 can be controlled to reduce the power and heat at a second power lower than the first power to reduce the speed at which the food generates bubbles, reduce the bubble height in the pot body 11, and avoid overflow.
[0158] In some embodiments, the bubble height detection device 7 can be an anti-overflow electrode, which can be used to detect the bubble height inside the pot 11. When a bubble rises and contacts the anti-overflow electrode, the presence of conductive substances such as water vapor inside the bubble will, to a certain extent, cause the circuit between the anti-overflow electrodes to become conductive. Even if the current intensity in the circuit changes, the change in current can be used to determine whether the bubble has reached the position of the anti-overflow electrode, thereby indirectly detecting the bubble height inside the pot 11.
[0159] In other embodiments, the bubble height detection device 7 can be a capacitive sensor, which can be used to detect the bubble height inside the pot 11. When bubbles are generated and rise inside the pot 11, they change the capacitance value of the capacitive sensor, thereby detecting the bubble height inside the pot 11 based on the change in capacitance value.
[0160] Of course, pressure sensors, cameras, and other devices can also be used to detect the height of air bubbles inside the pot 11.
[0161] According to some embodiments of the present invention, with reference to Figure 8 and Figure 9 The lid assembly 3 has an exhaust port 31 on the side facing the cooking body 1. The height of the exhaust port 31 relative to the bottom of the pot body 11 is H. During the cooking process, the height of the bubbles in the pot body 11 should always be lower than the height of the exhaust port 31 to ensure that no overflow occurs during the cooking process and to ensure the user experience.
[0162] The difference between the height H of the vent 31 relative to the bottom of the pot body 11 and the preset height is 5mm-15mm.
[0163] By limiting the difference between the height H of the exhaust port 31 relative to the bottom of the pot body 11 and the preset height to no less than 5mm, it is possible to ensure that a stable gaseous buffer layer is formed between the top of the bubble cloud and the exhaust port 31, effectively blocking the transmission path of liquid surface waves.
[0164] By limiting the difference between the height H of the exhaust port 31 relative to the bottom of the pot body 11 and the preset height to no more than 15mm, it is possible to ensure that heating efficiency loss is avoided due to excessive safety margin, and to prevent false overflow caused by bubble oscillation.
[0165] In some situations, such as when using cooking appliance 100 to make soup, the user may open the lid assembly 3 of cooking appliance 100 during the boiling stage of cooking to observe the cooking of the ingredients or to skim off the foam.
[0166] Combination Figures 8-16 In the embodiment shown, the cooking appliance 100 further includes: a lid opening and closing detection component 4, used to detect the opening and closing state of the lid assembly 3 on the cooking body 1; when the lid opening and closing detection component 4 detects that the lid assembly 3 is in the open state, the control device 6 controls the arc generating device 5 to stop working.
[0167] In other words, during the boiling stage, the electric arc generating device 5 will stop working after the lid assembly 3 is opened. This avoids the energy waste caused by the continuous operation of the electric arc generating device 5 when the lid is open, and provides precise power supply only when the lid is closed, eliminating ineffective energy consumption when the lid is open, extending the equipment life, and also preventing human injury from contact with the operating electric arc generating device 5.
[0168] After the user finishes opening the lid, it should be closed again. After the lid is closed, the cooking process of the cooking appliance 100 will still be in the boiling stage. The electric arc generator 5 should continue to work after the lid is closed to ensure that the electric arc generator 5 works in time to defoam the food in the cooking cavity 110 in time, so as to avoid the bubbles overflowing, affecting the user experience, causing liquid loss, and affecting the flavor of the food after cooking.
[0169] Reference Figure 8 and Figure 9 An electric arc generating device 5 is provided on the cover assembly 3, and a discharge part 51 is located on the side of the cover assembly 3 facing the cooking cavity 110.
[0170] In some embodiments, the arc generating device 5 includes a circuit control board 53, a primary coil, a secondary coil, and a discharge section 51. The primary coil and the secondary coil are arranged opposite to each other, with the primary coil connected to the circuit control board 53 and the secondary coil connected to the discharge section 51. In other embodiments, the arc generating device 5 further includes a heat dissipation device 52 and a heat insulation plate 54. The heat dissipation device 52 is disposed on the circuit control board 53 to dissipate heat from the circuit control board 53, and the heat insulation plate 54 is disposed between the secondary coil and the discharge section 51 to prevent the heat generated by the discharge section 51 from being transferred to the secondary coil.
[0171] A specific embodiment of the cooking utensil 100 is described below with reference to the accompanying drawings.
[0172] like Figures 8-10 As shown, the cooking appliance 100 includes: a cooking body 1, a lid assembly 3, a lid opening and closing detection component 4, an electric arc generating device 5, and a control device 6.
[0173] Reference Figure 16 The cooking appliance 100 includes a lid opening / closing detection component 4 and a control device 6. The lid opening / closing detection component 4 is used to detect the opening / closing state of the lid assembly 3 on the cooking body 1. The control device 6 is adapted to control the operation of the arc generating device 5 when the lid assembly 3 is in the closed state, and to control the arc generating device 5 to stop working when the lid assembly 3 is in the open state. The control device 6 controls the operation of the arc generating device 5 through the state of the lid assembly 3. On the one hand, it can avoid the energy waste caused by the continuous operation of the arc generating device 5 when the lid is open, and accurately supply power only when the lid is closed, eliminating ineffective energy consumption when the lid is open, extending the life of the equipment, and also avoiding injury caused by human contact with the operating arc generating device 5. On the other hand, it can also ensure that the arc generating device 5 works in time after the lid is closed, and promptly defoam the food in the cooking cavity 110, avoiding the overflow of bubbles, affecting the user experience, causing liquid loss, and affecting the flavor of the cooked food.
[0174] Combination Figures 11-15 The accompanying drawings illustrate a specific embodiment of the internal structure of the discharge section 51.
[0175] The discharge section 51 defines a receiving cavity 511. The opening and closing cover detection assembly 4 is disposed in the receiving cavity 511 defined by the discharge section 51. The opening and closing cover detection assembly 4 includes a trigger 41 and a sensor 42. The sensor 42 includes a first signal connection part 43 and a second signal connection part 44. The trigger 41 is disposed in the receiving cavity 511 and switches between a first state and a second state by its own gravity as the driving force during the opening and closing process of the cover assembly 3. The sensor 42 is used to generate a sensing signal when the trigger 41 is in the first state.
[0176] Reference Figure 14 and Figure 15 The trigger 41 is fixedly connected to the first signal connection part 43, that is, the first signal connection part 43 and the trigger 41 are kept connected. The signal connection between the first signal connection part 43 and the second signal connection part 44 is determined by whether the trigger 41 controls itself to contact the discharge part 51 which is fixedly connected to the second signal connection part 44. When the second signal connection part 44 connects to the first signal connection part 43, the arc generating device 5 is de-energized.
[0177] The trigger 41 is configured to deform at least partially under gravity, switching between a first state and a second state as the cover assembly 3 opens and closes. During the deformation of the trigger 41 under gravity, the state before and after deformation are the first state and the second state of the trigger 41, respectively.
[0178] When the trigger 41 is in the first state, the trigger 41 contacts the discharge part 51 so that the first signal connection part 43 and the second signal connection part 44 are connected in signal.
[0179] When the trigger 41 is in the second state, the trigger 41 is spaced apart from the discharge section 51 to disconnect the first signal connection section 43 and the second signal connection section 44.
[0180] Specifically, when the lid assembly 3 closes the opening 1101 of the cooking cavity 110, the discharge section 51 extends vertically downwards, and the trigger 41 is in the second state. At this time, the direction of gravity on the trigger 41 is the same as the extension direction of the trigger 41 itself. The trigger 41 can be suspended in the receiving cavity 511 and does not contact the wall of the receiving cavity 511, that is, the trigger 41 does not contact the discharge section 51 which is fixedly connected to the second signal connection section 44. The first signal connection section 43 and the second signal connection section 44 are disconnected, and the control module controls the arc generating device 5 to operate and release the arc for bubble breaking.
[0181] As the cover assembly 3 is opened, the direction of the force exerted by gravity on the trigger 41 changes. The direction of gravity points to one side perpendicular to the extension direction of the trigger 41. Since the trigger 41 itself is elastic and one end of the trigger 41 is fixed to the first signal connection part 43, as gravity changes, the end of the trigger 41 away from the first signal connection part 43 bends in the direction of gravity under the action of gravity. Thus, at least part of the trigger 41 deforms under the action of gravity, realizing its switching between the first state and the second state. The trigger 41 switches to the first state.
[0182] When the trigger 41 switches to the first state, it contacts the inner wall of the receiving cavity 511, and the signal between the first signal connection part 43 and the second signal connection part 44 is connected. The control module controls the arc generating device 5 to stop releasing the arc. The residual charge on the discharge part 51 can also be carried away by the trigger 41, preventing the user from being shocked by contacting the discharge part 51 with residual charge, and further improving the safety of the operation of the cooking appliance 100.
[0183] The linkage design of the trigger element 41 with the first signal connection part 43, the second signal connection part 44, and the discharge part 51 achieves structural integration. The contact design of the trigger element 41 and the discharge part 51 deeply integrates the lid opening and closing detection component 4 with the arc generating device 5, saving internal space of the lid assembly 3 and allowing for a more compact internal structure design of the cooking appliance 100. The trigger element 41 adopts an elastic structure sensitive to changes in the direction of gravity, enabling more sensitive detection of whether the lid assembly 3 is in a closed state and improving response speed.
[0184] According to some embodiments of the present invention, the receiving cavity 511 is a cylindrical cavity, and the triggering member 41 is an elastic member 412 extending axially along the cylindrical cavity.
[0185] Specifically, when the cover assembly 3 is closed, the cylindrical cavity extends vertically along its axis. The trigger element 41 is a conductive spring extending vertically, with its top end fixedly connected to the first signal connection part 43. It is suspended and fixed within the cylindrical cavity formed by the receiving cavity 511, relying on the first signal connection part 43. The sidewall of the receiving cavity 511 does not contact the conductive spring. That is, the conductive spring does not contact the discharge part 51 fixedly connected to the second signal connection part 44. When the first signal connection part 43 and the second signal connection part 44 are disconnected, the control module controls the arc generating device 5 to operate and release the arc for bubble breaking.
[0186] As the cover assembly 3 is opened, the axial extension direction of the cylindrical cavity is tilted relative to the vertical direction. The direction of the force of gravity acting on the conductive spring is at an angle to the extension direction of the conductive spring. Since one end of the conductive spring is fixed to the first signal connection part 43, the end of the trigger 41 away from the first signal connection part 43 bends downward under the action of gravity and deforms. The conductive spring switches to the first state and contacts the side wall of the receiving cavity 511 located on the lower side. The signal between the first signal connection part 43 and the second signal connection part 44 is connected, and the control module controls the arc generating device 5 to stop releasing the arc.
[0187] The following is combined Figures 11-13 The accompanying drawings illustrate two other specific embodiments of the internal structure of the discharge section 51.
[0188] Specifically, the first signal connection part 43 and the second signal connection part 44 are fixed in the receiving cavity 511, and the trigger 41 is movably disposed in the receiving cavity 511 so as to switch between the first state and the second state as the cover assembly 3 opens and closes.
[0189] As the lid assembly 3 opens and closes, the direction of gravity acting on the trigger 41 changes relative to the extension direction of the receiving cavity 511. When the lid assembly 3 closes the opening 1101 of the cooking cavity 110, the direction of gravity acting on the trigger 41 points away from the lid assembly 3. When the lid assembly 3 opens the opening 1101 of the cooking cavity 110, the direction of gravity acting on the trigger 41 points towards the lid assembly 3. Therefore, the trigger 41 is adapted to move within the receiving cavity 511 according to the direction of gravity. This movement enables switching between a first state and a second state.
[0190] In the first state, the trigger 41 contacts the first signal connection part 43 and the second signal connection part 44 to make the first signal connection part 43 and the second signal connection part 44 signal connected;
[0191] In the second state, the trigger 41 is spaced apart from both the first signal connection portion 43 and the second signal connection portion 44, so as to disconnect the first signal connection portion 43 and the second signal connection portion 44.
[0192] In some embodiments, refer to Figure 11 and Figure 12 When the trigger 41 is in the first state, the corresponding cover assembly 3 can be in the open state. When the trigger 41 is in the second state, the corresponding cover assembly 3 can be in the closed state.
[0193] Specifically, when the opening 1101 of the cooking cavity 110 is closed by the cover assembly 3, the extension direction of the discharge part 51 extends vertically away from the cover assembly 3, and the direction of gravity points away from the cover assembly 3. The trigger 41 provided in the receiving cavity 511 moves to the end of the receiving cavity 511 away from the cover assembly 3. When the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 close to the cover assembly 3, the trigger 41 is in the second state.
[0194] When the opening 1101 of the cooking cavity 110 is open in the lid assembly 3, and the lid assembly 3 is rotated to a certain angle, the direction of gravity of the trigger 41 points toward the side facing the lid assembly 3. When the trigger 41 located in the receiving cavity 511 moves to one end of the receiving cavity 511 near the lid assembly 3, and the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 near the lid assembly 3, the trigger 41 is in the first state.
[0195] like Figure 9 and Figure 10 The receiving cavity 511 is a cylindrical cavity, and the first signal connection part 43 and the second signal connection part 44 are arranged side by side in the receiving cavity 511, and are closer to the cover assembly 3 than the trigger 41.
[0196] The trigger 41 is a spherical structure 411, the diameter of which is greater than or equal to the distance between the first signal connection portion 43 and the second signal connection portion 44. This prevents the trigger 41 from moving further between the two portions after it contacts their ends, thus causing it to become stuck between them and unable to switch back to the second state.
[0197] Reference Figure 11 In other embodiments, when the trigger 41 is in the first state, the corresponding cover assembly 3 can be in the closed state, and when the trigger 41 is in the second state, the corresponding cover assembly 3 can be in the open state.
[0198] Specifically, when the opening 1101 of the cooking cavity 110 is closed by the cover assembly 3, the extension direction of the discharge part 51 extends vertically away from the cover assembly 3, and the direction of gravity points away from the cover assembly 3. The trigger 41 provided in the receiving cavity 511 moves to the end of the receiving cavity 511 away from the cover assembly 3. When the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 away from the cover assembly 3, the trigger 41 is in the first state.
[0199] When the opening 1101 of the cooking cavity 110 is open in the lid assembly 3, and the lid assembly 3 is rotated to a certain angle, the direction of gravity of the trigger 41 points toward the side facing the lid assembly 3. When the trigger 41 located in the receiving cavity 511 moves to one end of the receiving cavity 511 close to the lid assembly 3, and the contact point between the first signal connection part 43 and the second signal connection part 44 and the trigger 41 is located on the side of the trigger 41 away from the lid assembly 3, the trigger 41 is in the second state.
[0200] The receiving cavity 511 is a cylindrical cavity. The first signal connection part 43 and the second signal connection part 44 are arranged side by side in the receiving cavity 511. An insulating material slide rail is provided between the first signal connection part 43 and the second signal connection part 44. The trigger 41 is located in the slide rail and moves along the extension direction of the slide rail.
[0201] At least a portion of the first signal connection part 43 and the second signal connection part 44 bends and extends into the slide rail, and can receive the trigger part that slides to the end of the slide rail at the end. After the trigger 41 moves to the end of the slide rail, it simultaneously contacts the first signal connection part 43 and the second signal connection part 44, and connects the first signal connection part 43 and the second signal connection part 44.
[0202] The trigger 41 is a spherical structure 411 with a diameter smaller than the closest distance between the first signal connection part 43 and the second signal connection part 44, so that the trigger 41 can be limited by the first signal connection part 43 and the second signal connection part 44 after moving to the end of the slide rail.
