Description

Technical Field

[0001] This application belongs to the technical field of egg cooking devices, and particularly relates to a control method for an egg cooker and an egg cooker. Background Technology

[0002] Currently, there are two main types of control methods for household egg cookers. One type matches the number of eggs / egg doneness with the amount of water added. Different water amounts correspond to different numbers of eggs and doneness levels, including soft-boiled, medium-boiled, and hard-boiled. The doneness is matched by the time it takes to boil the water dry. The other type adds a fixed amount of water and then matches the number of eggs / egg doneness with a fixed heating time. Based on the user's selected doneness and number of eggs, the preset heating program is started to complete the cooking process.

[0003] Both of the aforementioned control methods rely on fixed water volume and heating time as their core control principles, lacking a real-time air temperature monitoring system within the heating chamber. They also fail to consider the impact of seasonal environmental changes, water temperature differences, and the time required to heat cold water to steam in high-altitude regions. This leads to inconsistencies in doneness, such as undercooked eggs in winter and overcooked eggs in summer. After cooking, current egg cookers rely on natural cooling, but the residual heat within the chamber continues to simmer the eggs. If not removed promptly, the eggs will become fully cooked, rendering the intended undercooked setting meaningless. Furthermore, the eggshell temperature is extremely high after cooking, typically exceeding 85°C, posing a significant risk of burns when handling the eggs directly. Existing solutions require auxiliary tools such as heat-resistant gloves and tongs, increasing the operational steps. Furthermore, handling the eggs by hand without these tools greatly reduces the ease of use and the risk of burns. Therefore, a new technology is urgently needed to address the two core problems of uneven doneness and burns when handling eggs. Summary of the Invention

[0004] In view of at least one of the above-mentioned technical problems in the prior art, the purpose of this application is to provide a control method and an egg cooker that can ensure that the preset doneness of the egg does not deviate and that the egg is not too hot to handle when taking it out.

[0005] The technical solution adopted in this application embodiment is a control method for an egg cooker. The egg cooker includes a controller, and a temperature measuring module, a timer, an air supply module, and a heating module respectively connected to the controller. The control method includes:

[0006] When the heating module heats the water in the egg cooker based on the selected egg cooking mode, the temperature of the water in the egg cooker is obtained by the temperature measuring module. If the water temperature reaches a preset temperature threshold, the temperature measuring module generates a first signal and sends it to the controller; The controller controls the timer to start the timing operation, and when the first timing duration is within the preset heating time range, the heating method of the heating module is adjusted based on the selected egg-cooking mode. After the heating module stops heating the water, the air supply module sends air into the egg cooking chamber of the egg cooker to lower the temperature of the eggs.

[0007] In an optional embodiment, the egg-cooking mode includes at least one of the following: a first egg-cooking mode, a second egg-cooking mode, and a third egg-cooking mode. The step of controlling the timer to start a timing operation via the controller, and adjusting the heating method of the heating module based on the selected egg-cooking mode when the first timing duration is within a preset heating time range, includes: When the first timing duration is within the first preset heating time range, the controller controls the heating module to operate in the first heating mode corresponding to the first egg-cooking mode; When the first timing duration is within the second preset heating time range, the controller controls the heating module to operate in the second heating mode corresponding to the second egg-cooking mode; When the first timing duration is within the third preset heating time range, the controller controls the heating module to operate in the third heating mode corresponding to the third egg-cooking mode; wherein... The first preset heating time threshold is less than the second preset heating time threshold, and the second preset heating time threshold is less than the third preset heating time threshold. By using different egg-cooking modes, users can obtain eggs at different levels of doneness to meet their diverse needs.

[0008] In an optional embodiment, obtaining the temperature of the water inside the egg cooker via a temperature measuring module includes: The temperature of the water in the egg cooker is obtained by a temperature sensor fixed to the heating module and inserted into the water. The temperature sensor allows for direct, fast, and accurate measurement of the water's true temperature, eliminating measurement errors.

[0009] In an optional embodiment, the preset temperature threshold is any value within the range of 80℃ to 100℃. At this temperature, the amount of steam generated by water evaporation can affect the doneness of the egg.

[0010] In an optional embodiment, the step of supplying air to the egg-cooking cavity through the air supply module includes: Air is supplied to the air duct of the air supply module by a fan. The air outlet of the air duct is connected to the egg-cooking cavity and is equipped with an air duct baffle. The air supplied by the fan pushes the air duct baffle to open the air outlet, and the air enters the egg-cooking cavity through the air outlet. The air supply module is ingeniously and reasonably designed, with a simple structure and good cooling effect.

[0011] In an optional embodiment, one end of the air duct extends upwards into the egg-cooking cavity, forming the air outlet. The air outlet is located near the first side of the egg-cooking cavity, blowing cold air from the first side to the second side. The cold air cools the eggs inside the cavity and then exits through the vent hole on the top of the egg-cooking cavity near the second side. This ensures that the airflow passes smoothly over the eggs and exits through the vent hole on the second side, preventing the air from swirling around inside the egg-cooking cavity and reducing the cooling effect.

[0012] In an optional embodiment, the air duct baffle is hinged to the side of the air outlet port away from the center of the egg-cooking cavity. The airflow within the air duct pushes the air duct baffle to rotate beyond a preset angle range. A limiting part on the port stops the air duct baffle, maintaining it at that rotation angle. When the fan stops supplying air to the air duct, the air duct baffle rotates under its own weight and seals the air outlet port. The limiting part restricts the rotation angle range of the air duct baffle so that after the airflow disappears, the air duct baffle always returns to the closed position under its own weight.

[0013] In an optional embodiment, after the air supply module initiates the air supply operation, the method further includes: Obtain the second timing duration of the timer; When the second timing period reaches the preset cooling time threshold, the controller controls the air supply module to stop supplying air. This ensures a stable and controllable cooling process, avoiding overcooling or undercooling; saves waiting and manual judgment time, achieving automation; and ensures that the cooling effect is essentially the same each time.

[0014] An egg cooker includes a controller, and a temperature measuring module, a timer, an air supply module, and a heating module respectively connected to the controller; The temperature measuring module is used to obtain the temperature of the water in the egg cooker when the heating module heats the water in the egg cooker based on the selected egg cooking mode; if the water temperature reaches a preset temperature threshold, the temperature measuring module generates a first signal and sends it to the controller. The controller is used to control the timer to start the timing operation, and when the first timing duration is within the preset heating time range, adjust the heating mode of the heating module based on the selected egg-cooking mode; The air supply module is used to supply air to the egg cooking chamber of the egg cooker after the heating module stops heating the water, so as to reduce the temperature of the eggs.

[0015] The egg cooker described in this application can accurately control various degrees of doneness, lock in the doneness through air cooling, and allow for direct removal and consumption after the program ends. The eggshells are not hot to the touch, making it safe and reliable. It provides a good user experience, is low in cost, easy to operate, and easy to implement.

[0016] In an optional embodiment, the egg cooker further includes a main body and a top cover, the top cover being fitted onto the main body and forming the egg cooking cavity with the main body; The temperature measuring module is a temperature sensor, which is mounted on the heating module and extends through the heating module into the water inside the egg cooker; The air supply module includes a fan, an air duct, and an air duct baffle. The air duct is located in the mounting cavity of the main body and extends upward to the first side of the egg cooking cavity to form an air outlet. The fan is located in the mounting cavity and is used to supply air into the air duct. The air duct baffle is located at the air outlet and is used to open the air outlet when the fan supplies air into the air duct and to close the air outlet when the air supply ends. This air supply module has a simple and reasonable structure, ingenious design, and convenient air supply. Furthermore, when the heating module is activated and the egg cooker is in the egg cooking state, the air duct will not cause steam leakage from the egg cooking cavity, ensuring the normal and smooth operation of the egg cooking process.

[0017] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: This application uses a temperature measuring unit to detect the water temperature to determine that the steam in the egg-cooking chamber has reached a level that can cook the eggs and triggers the timing. When the timing ends and the heating module stops heating, it automatically uses air cooling to lock in the cookedness, realizing rapid cooling and residual heat suppression after the eggs are cooked. This ensures that the preset cookedness does not deviate and that the eggs are not too hot to handle when taken out, thus solving the core defects of the prior art.

[0018] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this application.

[0031] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0032] This application provides a control method for an egg cooker, which is a dedicated kitchen appliance that uses electric heating to generate steam to cook various types of eggs (this application will use egg A as an example for explanation). A steaming rack or egg rack 62 is placed inside the egg cooker. Egg A is placed on the steaming rack or egg rack 62. When the water inside the egg cooker is heated, a large amount of high-temperature steam is generated. The high-temperature steam passes through the holes at the bottom of the steaming rack or egg rack 62 and evenly coats each egg A on the steaming rack or egg rack 62, cooking the egg A through heat conduction.

[0033] The egg cooker in this embodiment includes a controller 1, and a temperature measuring module 2, a timer 3, an air supply module 4, and a heating module 5, which are respectively connected to the controller 1.

[0034] The control method of the egg cooker according to an embodiment of this application will be described in detail below with reference to the accompanying drawings. Figure 1 This is a flowchart of the control method for an egg cooker according to an embodiment of this application, such as... Figure 1 As shown and combined Figure 3 The control method includes the following steps: S10, when the heating module 5 heats the water in the egg cooker based on the selected egg cooking mode, the temperature of the water in the egg cooker is obtained by the temperature measuring module 2.

[0035] After the user selects the egg cooking mode, the heating module 5 starts and heats the water in the egg cooker, which generates high-temperature steam to cook the egg A.

[0036] For example, the heating module 5 can be an electric heating module 5, which can be any of the following: a closed aluminum cast electric heating plate, a stainless steel thick film heating plate, a PTC ceramic heating element (Positive Temperature Coefficient, abbreviated as PTC), a tubular electric heating element, etc.

[0037] The temperature measuring module 2 can measure water temperature through direct contact, non-contact, or indirect contact with water. For example, it can estimate the temperature of the heating module 5 by detecting the infrared radiation emitted from the bottom or outer surface of its side wall, thereby indirectly inferring the water temperature; or it can measure the temperature of the metal surface in the center or adjacent area of ​​the heating module 5. Although the temperature of the heating module 5 itself is not exactly equal to the temperature of the water, there is a stable correlation. Through precise calibration, the real-time water temperature can be calculated very accurately by measuring the temperature of the heating module 5.

[0038] S20, if the water temperature reaches the preset temperature threshold, the temperature measuring module 2 generates a first signal and sends it to the controller 1.

[0039] After the heating module 5 is started, the water gradually heats up and produces steam, but the amount of steam is small and does not achieve the effect of heating egg A. Only when the water temperature rises to the preset temperature threshold will the amount of steam produced per unit time reach a certain amount, so that the steam has the effect of heating egg A. In this case, the temperature measuring module 2 generates a first signal and sends the first signal to the controller 1.

[0040] S30, the controller 1 controls the timer 3 to start the timing operation, and when the first timing duration is within the preset heating time range, the heating mode of the heating module 5 is adjusted based on the selected egg cooking mode.

[0041] After the temperature measuring module 2 detects that the water temperature has reached the preset temperature threshold and generates a first signal, it sends the first signal to the controller 1. Based on the received first signal, the controller 1 controls the timer 3 to start, and the timer 3 begins timing. The type and timing method of the timer 3 are not specifically limited in this application. For example, a countdown method can be used, that is, counting down from the set time to zero, and the timing ends.

[0042] During the first timing period of timer 3, i.e. the timed egg cooking period, controller 1 adjusts the heating mode of heating module 5 in real time according to the preset temperature-time curve corresponding to the egg cooking mode selected by the user, so as to achieve precise cooking.

[0043] Adjusting the heating method can specifically include: adjusting the power of heating module 5. The power curve of heating module 5 differs depending on the egg-cooking mode. For example, after the water temperature reaches 100°C, it may only require a short period of low power maintenance; or, after the water temperature reaches 100°C, the power of heating module 5 can be adjusted to maintain the water temperature at 100°C, ensuring sufficient heat penetration into egg A. Furthermore, for different egg-cooking modes, the power of heating module 5 can be maintained at a relatively stable level throughout the entire timing period.

[0044] Timer 3 counts down to the first timeout period, indicating that egg A has been cooked to the desired doneness according to the user's selected cooking mode. The first timeout period of timer 3 varies depending on the heating power of heating module 5 and the volume of the cooking cavity 61. Higher heating power results in a shorter first timeout period, and lower heating power results in a longer first timeout period. Similarly, a larger volume of the cooking cavity 61 results in a longer first timeout period, and a smaller volume of the cooking cavity 61 results in a shorter first timeout period.

[0045] S40, after the heating module 5 stops heating the water, air is supplied to the egg cooking chamber 61 of the egg cooker through the air supply module 4 to reduce the temperature of egg A.

[0046] When the timer 3 reaches the first timing duration, it sends a first signal to the controller 1. Based on the first signal, the controller 1 controls the heating module 5 to stop heating the water, that is, the heating module 5 is turned off. When the heating module 5 is turned off and no longer continues to heat, it is determined that the egg A has been cooked to the degree of doneness required by the user (target doneness). The controller 1 controls the air supply module 4 to supply air to the egg cooking chamber 61 of the egg cooker to cool the egg A and prevent the user from burning their hands when handling it.

[0047] After the heating module 5 stops heating, the air supply module 4 is immediately activated to blow cold air onto egg A, which rapidly cools egg A. This locks in the doneness corresponding to the egg cooking mode, preventing residual heat from cooking egg A further and increasing the degree of cooking, thus avoiding deviation from the degree of cooking corresponding to the egg cooking mode. In addition, cooling down the egg also facilitates the separation of the egg white from the inner membrane of the eggshell, making peeling the shell very easy and complete.

[0048] The temperature to which egg A is cooled can be room temperature, slightly above body temperature, or can be set by the user.

[0049] The control method of the egg cooker in this application embodiment uses a temperature measuring unit to detect the water temperature. It determines that the steam in the egg cooking chamber 61 has reached a level that can cook the egg A and triggers the timing. When the timing ends and the heating module 5 stops heating, it automatically uses air cooling to lock in the cooked egg. This achieves rapid cooling and residual heat suppression after the egg is cooked, ensuring that the preset cooked degree does not deviate and that the egg is not too hot to handle when taken out, thus solving the core defects of the prior art.

[0050] In one embodiment of this application, the egg-cooking mode includes at least one of the following: a first egg-cooking mode, a second egg-cooking mode, and a third egg-cooking mode. The first egg-cooking mode can be a soft-boiled egg mode, the second egg-cooking mode can be a medium-boiled egg mode, and the third egg-cooking mode can be a hard-boiled egg mode.

[0051] The step of controlling the timer 3 to start the timing operation via the controller 1, and adjusting the heating mode of the heating module 5 based on the selected egg-cooking mode when the first timing duration is within the preset heating time range, includes: When the first timing duration is within the first preset heating time range, the controller 1 controls the heating module 5 to operate in the first heating mode corresponding to the first egg cooking mode; When the first timing duration is within the second preset heating time range, the controller 1 controls the heating module 5 to operate in the second heating mode corresponding to the second egg cooking mode; When the first timing duration is within the third preset heating time range, the controller 1 controls the heating module 5 to operate in the third heating mode corresponding to the third egg-cooking mode; wherein The first preset heating time threshold is less than the second preset heating time threshold, and the second preset heating time threshold is less than the third preset heating time threshold.

[0052] For different egg-cooking modes, the controller 1 controls the heating module 5 to operate in the corresponding heating mode. The heating mode of the heating module 5 can be the same or different for different egg-cooking modes. That is, the first heating mode, the second heating mode, and the third heating mode can be the same (all continuously fine-tuning the heating power of the heating module 5 to maintain the uniformity of the temperature field in the egg-cooking cavity 61), or they can be different.

[0053] For example, the first, second, and third heating methods are identical. When the first timing duration falls within the first, second, or third preset heating time range, the heating module 5 operates with the same constant heating power. To cook eggs A to different degrees of doneness under different egg-cooking modes, this is achieved by changing the preset heating time range. Specifically, when the first egg-cooking mode is a soft-boiled egg mode, the second egg-cooking mode is a medium-boiled egg mode, and the third egg-cooking mode is a hard-boiled egg mode, the first preset heating time range corresponding to the first egg-cooking mode is set to the shortest, the third preset heating time range corresponding to the third egg-cooking mode is set to the longest, and the second preset heating time range corresponding to the second egg-cooking mode is set between the first and third preset heating time ranges, thus achieving different degrees of doneness for eggs A.

[0054] The first preset heating time range corresponds to the first egg-cooking mode, the second preset heating time range corresponds to the second egg-cooking mode, and the third preset heating time range corresponds to the third egg-cooking mode.

[0055] The first, second, and third preset heating time ranges all start from when the water temperature reaches a preset temperature threshold.

[0056] For example, the first preset heating time range is 6 minutes, the second preset heating time range is 9 minutes, and the third preset heating time range is 13 minutes.

[0057] In one embodiment of this application, obtaining the temperature of the water inside the egg cooker via the temperature measuring module 2 includes: The temperature of the water in the egg cooker is obtained by a temperature sensor fixed to the heating module 5 and inserted into the water in the egg cooker.

[0058] Temperature measurement module 2 uses a temperature sensor, such as an NTC sensor (negative temperature coefficient thermistor). The main body 6 of the NTC sensor is fixed to the heating module 5. The NTC's sensing head is in direct contact with the water being measured, allowing for direct, rapid, and accurate measurement of the water's true temperature, eliminating errors associated with indirect measurements. Furthermore, water has a high heat capacity and excellent thermal conductivity. After being immersed in water, the NTC sensing head rapidly exchanges heat with the water, and its resistance value closely follows the actual temperature change with almost no delay, achieving rapid response and precise temperature control.

[0059] The NTC sensor can be fixed on the non-heat-generating substrate of the heating module 5. This prevents the heating element of the heating module 5 from affecting the NTC sensor when it heats up.

[0060] In one embodiment of this application, the preset temperature threshold can be any value within the range of 80℃ to 100℃. When the heating module 5 heats the water to any temperature within the range of 80℃ to 100℃, it is determined that the amount of steam generated by the evaporation of water can affect the cooking degree of egg A, causing the egg white and egg liquid to gradually solidify.

[0061] The preset temperature threshold can be any value between 80℃ and 100℃. For example, the preset temperature threshold can be 85℃, 90℃, 92℃, 95℃, 98℃, 100℃, etc.

[0062] In one embodiment of this application, such as Figure 5 and Figure 6 As shown, the air supply module 4 supplies air to the egg-cooking cavity 61, including: The fan 41 of the air supply module 4 supplies air to the air duct 42 of the air supply module 4. The air outlet 43 of the air duct 42 is connected to the egg cooking cavity 61 and is provided with an air duct baffle 44. The air supplied by the fan 41 into the air duct 42 pushes the air duct baffle 44 to open the air outlet 43 and enters the egg cooking cavity 61 through the air outlet 43.

[0063] For example, when the fan 41 of the air supply module 4 is started, it drives the surrounding air to flow, forming an airflow. The airflow enters the air duct 42 and pushes the air duct baffle 44 at the air inlet end of the air duct 42 to open (see...). Figure 5 The airflow then enters the egg-cooking cavity 61, blowing air onto the egg A inside to cool it and prevent the user from burning their hands when handling the egg. When the egg A has been cooled for a preset time or reached a preset temperature, the fan 41 stops rotating and ceases blowing air into the air duct 42 and the egg-cooking cavity 61. Simultaneously, the air duct baffle 44 closes the air outlet 43 of the air duct 42 (see [link]). Figure 6 This prevents steam from escaping through the air duct 42 during the egg-cooking process, thus affecting the doneness of the eggs.

[0064] In one embodiment of this application, the following is continued: Figure 5 and Figure 6 One end of the air duct 42 extends upward into the egg-cooking cavity 61, forming the air outlet 43. The air outlet 43 is close to the first side of the egg-cooking cavity 61, blowing cold air from the first side of the egg-cooking cavity 61 to the second side. After cooling the eggs in the egg-cooking cavity 61, the cold air is discharged through the vent 71 on the top of the egg-cooking cavity 61 near the second side. The first side and the second side are opposite each other, so that the cold air blown out by the air outlet 43 of the air duct 42 blows from the first side to the second side. After the air blows over the egg A, it can be smoothly discharged through the vent 71 on the second side, avoiding the air from swirling around in the egg-cooking cavity 61 and failing to achieve the cooling effect.

[0065] With the vent 71 open, a small amount of steam will escape through the vent 71 when the egg is boiling, maintaining a slight pressure inside the egg-boiling chamber 61. After the egg is boiled, the heating module 5 stops heating, and the air supply module 4 supplies air to the egg-boiling chamber 61. The air cooled by the egg A is then discharged through the vent 71, enhancing the function of the vent 71. The structural design is ingenious and reasonable.

[0066] In one embodiment of this application, such as Figure 5 and Figure 6As shown, the air duct baffle 44 is hinged to the side of the air outlet 43 away from the center of the egg cooking cavity 61. The air in the air duct 42 pushes the air duct baffle 44 to rotate beyond a preset angle range. The limiting part on the port stops the air duct baffle 44, and the air duct baffle 44 remains at this rotation angle. When the fan 41 stops blowing air into the air duct 42, the air duct baffle 44 rotates under its own gravity and seals the port of the air outlet 43.

[0067] By using a simple physical limiter, the movement of the air duct baffle 44 is forcibly constrained within a safe range where "gravitational potential energy can always cause it to automatically reset," thus fundamentally eliminating the risk of jamming and ensuring the absolute reliability of the function.

[0068] By setting a physical limiter of less than 90°, such as a limit post or stop, the range of motion of the air duct baffle 44 is always within the range where the center of gravity torque can automatically pull it back to the closed position. No matter how strong the wind is, it can only open to the maximum angle (such as 45° to 60°), and once the wind disappears, the torque generated by the center of gravity can always pull it back to the closed position.

[0069] When the egg-cooking program ends and cooling begins, fan 41 starts, and the air duct baffle 44 is blown open by the airflow, allowing cool air to enter the egg-cooking chamber 61. Once cooling is complete and fan 41 stops, the air duct baffle 44 automatically falls under its own gravity, closing the air duct 42 and effectively preventing steam from escaping naturally to the outside during the egg-cooking process. Moreover, the automatic closing of the air duct baffle 44 is achieved using gravity, a purely physical mechanism, eliminating the need for additional springs, motors, or solenoid valves. The structure is extremely simple and reliable, while also reducing material costs and assembly complexity.

[0070] In one embodiment of this application, such as Figure 2 As shown, after the air supply module 4 starts the air supply operation, the method further includes: S50, obtain the second timing duration of the timer 3; S60, when the second timing duration reaches the preset cooling time threshold, the controller 1 controls the air supply module 4 to stop supplying air.

[0071] The air supply duration is measured by timer 3. When the air supply duration reaches the preset cooling time threshold, it is determined that egg A has been cooled to the required temperature, and controller 1 controls air supply module 4 to stop supplying air.

[0072] For example, controller 1 stops fan 41 from rotating, thereby stopping the air supply module 4 from supplying air to egg A in egg cooking cavity 61. When fan 41 stops, no airflow continues to enter air duct 42, and therefore no airflow enters egg cooking cavity 61. At this time, cooling is complete, and egg A can be taken out for consumption.

[0073] The second timing duration (i.e., air supply duration) of the timer 3 varies depending on the air supply volume of the fan 41 and the volume of the egg cooking cavity 61. The larger the air supply volume, the shorter the second timing duration; the smaller the air supply volume, the longer the second timing duration. The larger the volume of the egg cooking cavity 61, the longer the second timing duration; the smaller the volume of the egg cooking cavity 61, the shorter the second timing duration.

[0074] For example, the preset cooling time threshold can be any value within the range of 3-8 minutes. When the second timing duration of timer 3 reaches any time within the range of 3-8 minutes, the air cooling program ends.

[0075] For example, this application may also include a prompting module. When the second timing duration reaches the preset cooling time threshold and the controller 1 controls the air supply module 4 to stop supplying air, the controller 1 also controls the prompting module to issue a reminder warning to the user that cooling has been completed.

[0076] The prompting module may include various modules that perform prompting operations through sound, light, vibration, etc., including but not limited to indicator lights, buzzers, speakers, displays, etc.

[0077] This application adopts a multi-signal linkage control principle to achieve precise coordination of water temperature detection, heating, timing, and air cooling in the egg cooker, simplifying the overall control process and enabling one-click selection of doneness and full automation without manual intervention.

[0078] This application also provides an egg cooker, such as... Figures 4 to 6 As shown, the egg cooker includes a controller 1, and a temperature measuring module 2, a timer 3, an air supply module 4, and a heating module 5, which are respectively connected to the controller 1.

[0079] The temperature measuring module 2 is used to obtain the temperature of the water in the egg cooker when the heating module 5 heats the water in the egg cooker based on the selected egg cooking mode; if the water temperature reaches a preset temperature threshold, the temperature measuring module 2 generates a first signal and sends it to the controller 1.

[0080] The controller 1 is used to control the timer 3 to start the timing operation, and when the first timing duration is within the preset heating time range, adjusts the heating mode of the heating module 5 based on the selected egg-cooking mode.

[0081] The air supply module 4 is used to supply air to the egg cooking chamber 61 of the egg cooker after the heating module 5 stops heating the water, so as to reduce the temperature of the egg.

[0082] The egg cooker in this embodiment uses a temperature measuring module 2 to monitor the water temperature in real time. If the water temperature exceeds a preset threshold, a timer automatically starts, ensuring that the heating environment is heated at the same temperature for different egg quantities, and that the eggs absorb steam at the same rate, thus ensuring precise control of doneness. Furthermore, the heating module 5 operates according to different egg-cooking modes, accurately controlling various levels of doneness. After the egg-cooking process is complete, automatic air cooling is activated to lock in the doneness. Once the entire process is finished, egg A can be directly removed for consumption; the shell is not hot to the touch, ensuring safety, reliability, and easy operation. This application offers a good user experience, low cost, convenient operation, and is easy to implement.

[0083] In one embodiment of this application, the following is continued: Figures 4 to 6 The egg cooker also includes a main body 6 and a top cover 7. The top cover 7 covers the main body 6 and together with the main body 6, forms the egg cooking cavity 61. A steaming rack or egg rack 62 is placed inside the egg cooking cavity 61, and the eggs A to be cooked are placed on the steaming rack or egg rack 62. The top cover 7 can be made of transparent material to facilitate observation of the egg cooking cavity 61 and achieve visual monitoring. A steam vent 71 is located on one side of the top of the top cover 7 to balance the air pressure inside and outside the cavity, prevent excessive pressure, and form an air outlet during the air cooling stage to facilitate smooth airflow and improve the cooling effect.

[0084] The temperature measuring module 2 is a temperature sensor, particularly an NTC sensor. The temperature sensor is mounted on the heating module 5 and extends through the heating module 5 into the water inside the egg cooker. This allows for direct, rapid, and accurate measurement of the water's true temperature, reducing measurement errors.

[0085] The air supply module 4 includes a fan 41, an air duct 42, and an air duct baffle 44. The air duct 42 is located in the mounting cavity of the main body 6 and extends upward to the first side of the egg cooking cavity 61 to form an air outlet 43. The fan 41 is located in the mounting cavity and is used to supply air into the air duct 42. The air duct baffle 44 is located at the air outlet 43 and is used to open the air outlet 43 when the fan 41 supplies air into the air duct 42 and to close the air outlet 43 when the air supply ends. This air supply module 4 has a simple and reasonable structure, ingenious design, and convenient air supply. Furthermore, when the heating module 5 is started and the egg cooker is in the egg cooking state, the air duct 42 will not cause steam leakage from the egg cooking cavity 61, ensuring the normal and smooth operation of the egg cooking process.

[0086] For example, the air duct baffle 44 is rotatably disposed at the air outlet 43 of the air duct 42, and rotates open under the pushing action of the upward airflow sent into the air duct 42 by the fan 41. After the fan 41 stops blowing air, the air duct baffle 44 rotates back under its own gravity and closes the port of the air outlet 43 of the air duct 42, cutting off the connection between the air duct 42 and the egg cooking cavity 61, so as to prevent the steam in the egg cooking cavity 61 from leaking to the outside through the air duct 42 during egg cooking, thus affecting the egg cooking effect.

[0087] When the air duct baffle 44 opens the port of the air outlet 43 of the air duct 42, the maximum rotation angle is controlled at 60°. This ensures that after the wind disappears, the torque generated by the center of gravity of the air duct baffle 44 can always pull it back to the closed position, thus ensuring the absolute reliability of the return of the air duct baffle 44.

[0088] Furthermore, the angle range of the air duct baffle 44 rotating from the closed position to the open position under the action of wind is preferably limited to 45° to 60°, so that the air duct baffle 44 can always automatically return to its original position after the wind disappears.

[0089] In one embodiment of this application, a limiting part is provided at the air outlet 43 of the air duct 42. The limiting part is used to rotate the air duct baffle 44 from the closed position to the open position, and when it rotates to the maximum angle, it restricts the air duct baffle 44 from continuing to rotate. Under the combined action of the wind force and the limiting part, the air duct baffle 44 is kept in this state, so that the air can smoothly enter the egg cooking cavity 61 from the air duct 42 to cool the egg A.

[0090] This application does not specify the exact structure or location of the limiting part. It is sufficient that the rotation range of the air duct baffle 44 can be limited.

[0091] In one embodiment of this application, the following is continued: Figure 5 and Figure 6 One end of the air duct 42 extends upward into the egg-cooking cavity 61, forming the air outlet 43. The air outlet 43 is located near the first side of the egg-cooking cavity 61 and is used to blow cold air from the first side of the egg-cooking cavity 61 to the second side of the egg-cooking cavity 61. After cooling the eggs in the egg-cooking cavity 61, the cold air is discharged through the vent 71 on the top of the egg-cooking cavity 61 near the second side. The first side and the second side are opposite each other, so that the cold air blown out by the air outlet 43 of the air duct 42 blows from the first side to the second side. After the air blows over the egg A, it can be smoothly discharged through the vent 71 on the second side, avoiding the air from swirling around in the egg-cooking cavity 61 and failing to achieve the cooling effect. Figure 5 The central airway baffle 44 is in the open position. Figure 5 The arrows in the diagram indicate the direction of wind flow.

[0092] The air duct 42 and the main body 6 can be integrally injection molded, or they can be separate structures that are assembled together. This application does not make any specific limitations on this.

[0093] like Figure 7 As shown, the egg cooker in this embodiment of the application is also equipped with a quantitative measuring cup 9. Using the quantitative measuring cup 9, the water addition operation is simplified, and a fixed preset water volume is used to adapt to the soft, medium, hard-boiled, and fully cooked ranges of eggs, such as 1-6 eggs A (the number of eggs A is not limited, and can also be 1-8). This eliminates the need for multiple graduation lines and prevents water addition errors.

[0094] When boiling eggs, first use measuring cup 9 to measure the preset amount of water. The preset amount of water can be selected and determined according to the volume of the egg boiling chamber 61 of the egg cooker, for example, 100ml, 120ml, 130ml, etc.

[0095] The egg-cooking process of different egg-cooking modes of this application is described below with specific embodiments: Example 1: Soft-boiled egg mode 1. Standardized preparation: Use a measuring cup 9 to measure 120ml of water and pour it into the heating chamber below the egg cooking chamber 61. Place the egg rack 62 in the designated position inside the egg cooking chamber 61, put in, for example, 5 eggs A, and cover with the transparent top cover 7 to construct a basically sealed egg cooking chamber 61.

[0096] 2. Mode Activation: Select the "Soft Egg" mode via input module 8 (touch panel). The egg cooker will automatically load the corresponding heating curve and 6-minute timing parameters, starting the closed-loop temperature control program. This ensures that the heating temperature is the same for different egg quantities and that the eggs absorb steam at the same rate, ensuring precise control over doneness.

[0097] 3. Dynamic temperature control and timing: The temperature sensor monitors the temperature of the water in the heating chamber in real time. When the water temperature reaches the preset temperature threshold, the controller 1 controls the timer 3 to start a 6-minute countdown. During this period, the heating power is continuously fine-tuned to maintain the uniformity of the temperature field.

[0098] 4. Active air cooling: After the countdown ends, the controller 1 controls the heating module 5 to cut off the power, and simultaneously starts the air supply module 4 and the timer 3. The air duct baffle 44 opens and guides the cold air to form a full-area airflow in the egg cooking cavity 61, quickly removing the residual heat.

[0099] 5. Finished Product Retrieval: When timer 3 reaches 5 minutes, controller 1 controls the air supply module 4 to shut off, ending the air cooling program. At the same time, controller 1 controls the buzzer to sound an alarm, and the egg cooker enters standby mode. At this time, the temperature inside the egg cooking chamber 61 drops below 45℃. The egg A can be removed by opening the lid. The finished product has egg yolks and egg whites in a semi-solid state, and the 5 eggs A are cooked to a uniform degree.

[0100] Example 2: Medium-boiled egg mode 1. Standardized preparation: Use a measuring cup 9 to measure 120ml of water and pour it into the heating chamber below the egg cooking chamber 61. Place the egg rack 62 in the designated position inside the egg cooking chamber 61, put in, for example, 6 eggs A, and cover with the transparent top cover 7 to construct a basically sealed egg cooking chamber 61.

[0101] 2. Mode Activation: Select the "Medium-cooked Egg" mode via input module 8. The egg cooker will automatically load the corresponding heating curve and 9-minute timing parameters, starting the closed-loop temperature control program. This ensures that the heating environment has the same heating temperature for different egg quantities, and that the eggs absorb the same amount of steam, ensuring precise control of doneness.

[0102] 3. Dynamic temperature control and timing: The temperature sensor monitors the temperature of the water in the heating chamber in real time. When the water temperature reaches the preset temperature threshold, the controller 1 controls the timer 3 to start a 9-minute countdown. During this period, the heating power is continuously fine-tuned to maintain the uniformity of the temperature field.

[0103] 4. Active air cooling: After the countdown ends, the controller 1 controls the heating module 5 to cut off the power, and simultaneously starts the air supply module 4 and the timer 3. The air duct baffle 44 opens and guides the cold air to form a full-area airflow in the egg cooking cavity 61, quickly removing the residual heat.

[0104] 5. Finished Product Retrieval: When timer 3 reaches 5 minutes, controller 1 shuts off the air supply module 4, ending the air cooling program. Simultaneously, controller 1 activates the buzzer to sound an alarm, and the egg cooker enters standby mode. At this time, the temperature inside the egg cooking chamber 61 drops below 45℃. Egg A can be removed by opening the lid. The finished product exhibits a stable state with completely solidified egg white and semi-runny yolk, and all 6 eggs A are uniformly cooked.

[0105] Example 3: Hard-boiled egg cooking mode 1. Standardized preparation: Use a measuring cup 9 to measure 120ml of water and pour it into the heating cavity below the egg cooking cavity 61. Place the egg rack 62 in the designated position inside the egg cooking cavity 61, put in, for example, 3 eggs A, and cover with the transparent top cover 7 to construct a basically sealed egg cooking cavity 61.

[0106] 2. Mode Activation: Select the "Fully Hard-boiled Egg" mode via input module 8. The egg cooker will automatically load the corresponding heating curve and 13-minute timing parameters, starting the closed-loop temperature control program. This ensures that the heating temperature is the same for different egg quantities and that the eggs absorb steam at the same rate, ensuring precise control of doneness.

[0107] 3. Dynamic temperature control and timing: The temperature sensor monitors the temperature of the water in the heating chamber in real time. When the water temperature reaches the preset temperature threshold, the controller 1 controls the timer 3 to start a 13-minute countdown. During this period, the heating power is continuously fine-tuned to maintain the uniformity of the temperature field.

[0108] 4. Active air cooling: After the countdown ends, the controller 1 controls the heating module 5 to cut off the power, and simultaneously starts the air supply module 4 and the timer 3. The air duct baffle 44 opens and guides the cold air to form a full-area airflow in the egg cooking cavity 61, quickly removing the residual heat.

[0109] 5. Finished Product Retrieval: When timer 3 reaches 5 minutes, controller 1 shuts off the air supply module 4, ending the air cooling program. Simultaneously, controller 1 activates the buzzer to sound an alarm, and the egg cooker enters standby mode. At this time, the temperature inside the egg cooking chamber 61 drops below 45℃. Egg A can be removed by opening the lid. The finished product is in a stable state where the egg white and yolk are completely solidified, and the three eggs A are cooked to a uniform degree.
