Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and specifically to a multi-purpose convenient cooking device and method applicable to instant rice, rice noodles, and noodles. Background Art

[0002] Currently, there are a variety of cooking devices on the market, but most of them focus on single cooking functions or ingredient types. For consumers, if they need to cook different types of ingredients, they usually need to purchase and use multiple cooking devices, which not only increases the occupation of kitchen space but also raises the overall cost of household cooking devices.

[0003] Existing instant rice cooking devices are mainly represented by rice cookers. Although they have mature functions, they are relatively large in size, it is difficult to ensure uniform heating, and often need to manually adjust the cooking time in high-altitude areas, making them less convenient to use. For cooking rice noodles and noodles, currently, it mainly relies on traditional cooking pots, which require users to constantly stir to prevent the ingredients from sticking together. The operation is cumbersome and prone to breaking the ingredients, affecting the quality of the finished product.

[0004] Although there are some multi-functional cooking devices on the market, they often simply integrate multiple functions together, lacking an organic combination between functions and unable to provide the optimal cooking solution for specific ingredients. For example, existing devices are difficult to flexibly switch between two cooking methods of steaming and boiling, and cannot meet the needs of ingredients such as glutinous rice balls that require composite cooking processes.

[0005] In addition, existing cooking devices generally have the problem of low energy utilization efficiency. In the steaming process of traditional steamers, the steam diffuses unevenly, and the condensed water easily drips onto the ingredients, affecting the taste of the ingredients; while cooking pots are prone to local overheating, resulting in uneven heating of the ingredients and uneven cooking effects. Summary of the Invention

[0006] The present invention provides a multi-purpose convenient cooking device and method applicable to instant rice, rice noodles, and noodles to solve the problems in the above background art.

[0008] Preferably, the inner pot body at least includes an inner pot body for cooking rice noodles / noodles and an inner pot body for steaming rice. Among them, a plurality of steam diversion holes are provided at the bottom of the inner pot body for steaming rice. The aperture of the steam diversion holes is 1.2 mm to 2.5 mm, and the distribution density is 8 to 12 per square centimeter.

When the inner pot body sinks into the water, water enters the inner pot body through the inclined guiding holes to form a rotating water flow, causing the noodles or rice noodles in the inner pot body to rotate; The inlet diameter of the inclined guiding hole is larger than the middle diameter, and the outlet diameter is larger than the middle diameter.

[0009] Preferably, the device further includes at least one temperature sensor and at least one water level sensor, and the sensors are all electrically connected to the control module; The control module is configured to adjust the heating power of the electric heating component and / or the motion parameters of the lifting drive mechanism according to the feedback signals of the temperature sensor and / or the water level sensor; and when the water level sensor detects that the water level exceeds the preset safety range or the temperature sensor detects that the temperature reaches the preset critical value, adjust the heating power of the electric heating component or stop heating.

[0010] Preferably, the electric heating component includes at least two partition heating units whose heating powers are independently controlled by the control module; The control module is configured to, based on the feedback signal of the temperature sensor and according to the currently executed cooking mode program, differentially adjust the heating intensities of the partition heating units, so that during the boiling stage of the rice noodle / noodle mode, the liquid temperature in the central area of the outer pot body is 2°C to 5°C higher than the liquid temperature in the surrounding area.

[0011] Preferably, the control module is integrated with a compensation program module, and the compensation program module is configured to, when detecting or receiving a signal indicating that the current ambient air pressure is lower than the preset standard value, extend the time for the electric heating component to generate and maintain steam and / or increase the output power of the electric heating component during the operation sequence of the instant rice mode.

[0012] Preferably, the device further includes a wireless communication module for establishing a wireless connection with a mobile terminal device; The control module is configured with a remote control program that allows the user to select a cooking mode, set cooking parameters, and monitor the cooking progress through the mobile terminal device.

[0013] Preferably, the lifting drive mechanism includes a stepper motor and a transmission shaft connected to the output end of the stepper motor. A threaded bushing is connected to the transmission shaft, and the threaded bushing is driven by the stepper motor to move. A support frame is connected to the threaded bushing, and the support frame is connected to the inner pot body.

[0014] The present application also discloses a multi-purpose and convenient cooking method for instant rice, rice noodles, and noodles, including the following steps: S1: According to the selected ingredient type, start the corresponding preset cooking mode program; S2: If the instant rice mode program is started, then execute: Control the lifting drive mechanism to move the inner pot body to the first working position, so as to form a steam cavity with a preset height between the bottom of the inner pot body and the bottom of the outer pot body; Control the electric heating component to output power in a pulsed or segmented manner to heat the water in the outer pot body to generate and maintain steam in the steam cavity; S3: If the rice noodle / noodle mode program is started, then execute: Control the lifting drive mechanism to move the inner pot body to the second working position; Control the electric heating component to heat the liquid in the outer pot body; Control the lifting drive mechanism to make the inner pot body perform a periodic lifting motion, and the periodic lifting motion includes lifting the inner pot body by H to H every T to T N seconds and keeping it for 1 to 3 seconds. i centimeters.

[0015] Preferably, in step S3 of the rice noodle / noodle mode program, the periodic lifting motion performed by the inner pot body includes: Within a preset initial time period T1 after the start of this mode program, control the lifting drive mechanism to drive the inner pot body to lift and lower at a first frequency F1, and the amplitude of each lift and lower is H1 centimeters; After the preset initial time period T1 ends, within the subsequent time period T2 until the end of this mode program, control the lifting drive mechanism to drive the inner pot body to lift and lower at a second frequency F2, and the amplitude of each lift and lower is H2 centimeters.

[0016] Preferably, the control module is further configured with a combined cooking mode, and this combined cooking mode includes: First, perform a pre-boiling process on the ingredients in the inner pot body at the second working position, and the boiling time is a preset T3 minutes; Then control the lifting drive mechanism to lift the inner pot body to the first working position, and steam the ingredients through the steam in the steam cavity, and the steaming time is a preset T4 minutes.

[0017] The present invention has the following beneficial effects: 1. The multi-purpose convenient cooking device of the present application realizes the flexible switching between two cooking methods of steaming and boiling through the innovative design of the inner and outer pot bodies and the lifting drive mechanism. Traditional cooking equipment usually can only achieve a single cooking method, while this device can form a steam cavity at the first working position for steaming, or partially immerse the inner pot body in water at the second working position for boiling, greatly improving the application range of the equipment. Especially the combined cooking mode organically combines the two steps of pre-boiling and steaming, significantly improving the quality and taste of the finished product.

[0018] 2. The device adopts an innovative mechanism of periodic lifting and lowering of the inner pot body, effectively solving the common adhesion problem during the traditional cooking of rice noodles and noodles. Through the precise control of the lifting drive mechanism by the control module, the inner pot body performs periodic lifting and lowering movements at a preset frequency and amplitude during the cooking process, enabling the ingredients to be fully stirred in water without manual intervention. In addition, the two-stage lifting strategy (high frequency and large amplitude in the initial stage, low frequency and small amplitude in the later stage) further optimizes the cooking effect. The high frequency and large amplitude movement in the initial stage promotes the rapid dispersion and uniform heating of the ingredients, while the low frequency and small amplitude movement in the later stage ensures the gentle ripening of the ingredients without damaging their shape, ultimately achieving the effect of uniform heating and non-adhesion of the rice noodles / noodles.

[0019] 3. The device integrates a compensation program module to automatically detect or receive the current ambient air pressure information. When the detected air pressure is lower than the preset standard value, it intelligently extends the heating time and increases the output power of the electric heating component to compensate for the influence of the reduced steam temperature in a low air pressure environment.

[0020] 4. The device adopts the technologies of zone heating and differential temperature control, significantly improving the cooking efficiency and ingredient quality. Traditional cooking equipment usually uses a single heating unit and cannot achieve precise control of the regional temperature. In this application, the electric heating component includes multiple independently controlled zone heating units, and the control module can differentially adjust the power of each zone heating unit. For example, in the rice noodles / noodles mode, the water temperature in the central area of the pot body is 2°C to 5°C higher than that in the surrounding area. The temperature gradient control helps the ingredients to be heated more evenly, avoiding the common problems of local overcooking or undercooking in traditional cooking methods.

[0021] 5. The device is designed with an efficient steam utilization system and a water resource recycling mechanism, greatly improving the energy and water resource efficiency. The steam diversion holes (with a pore diameter of 1.2 mm to 2.5 mm and a distribution density of 8 to 12 per square centimeter) carefully designed at the bottom of the inner pot body ensure the uniform distribution of steam into the inner pot body, effectively avoiding the problems of concentrated or uneven steam in traditional steam cookers. The condensate diversion grooves on the inner side wall are connected to the steam diversion holes, draining the condensate on the inner pot body wall back to the steam cavity for reheating and utilization. This not only avoids the problem of deteriorated taste caused by condensate dripping on the ingredients but also significantly improves the water resource utilization efficiency and thermal energy utilization efficiency.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Referring to Figures 1 to 11 , this application discloses a multi-purpose convenient cooking device applicable to instant rice, rice noodles, and noodles, including: a base 1, a pot body assembly 2, an electric heating assembly 3, and a lifting drive mechanism 4.

[0026] The base 1 is internally provided with a control module, and the control module includes a microprocessor, a memory, and an input / output interface. The control module is electrically connected to the electric heating assembly 3 and the lifting drive mechanism 4 for controlling the working process of the entire device.

[0027] The pot body assembly 2 is detachably mounted on the base 1 and includes an outer pot body 21 and an inner pot body 22. The outer pot body 21 is fixedly mounted on the base 1 for containing water or other liquids. The inner pot body 22 can move up and down within the outer pot body 21 for containing the ingredients to be cooked.

[0028] The electric heating assembly 3 is disposed between the base 1 and the outer pot body 21, and is used to heat the liquid in the outer pot body 21. The electric heating assembly 3 includes at least two zone heating units, and the zone heating units are independently controlled by the control module for their heating power, and the control module independently controls the heating power of the zone heating units.

[0029] The lifting drive mechanism 4 is connected to the inner pot body 22 and is controlled by the control module. The lifting drive mechanism 4 includes a stepper motor, a transmission shaft, a threaded bushing, and a support frame. The output end of the stepper motor is connected to the transmission shaft, the transmission shaft is connected with the threaded bushing, the threaded bushing is connected with the support frame, and the support frame is connected with the inner pot body 22. By driving the movement of the threaded bushing by the stepper motor, the inner pot body 22 is driven to move up and down.

[0030] The lifting drive mechanism 4 is configured to drive the inner pot body 22 to switch between at least two preset working positions in the outer pot body 21: Referring to Figure 3 , the first working position: a steam cavity 23 with a preset height is formed between the bottom of the inner pot body 22 and the bottom of the outer pot body 21, which is used for steam cooking of the ingredients in the inner pot body 22; Referring to Figure 4 , the second working position: at least part of the inner pot body 22 sinks into the liquid contained in the outer pot body 21, which is used for boiling the ingredients in the inner pot body 22.

[0031] Referring to Figure 7 and Figure 8 , the inner pot body at least includes an inner pot body for cooking rice noodles / noodles and for steaming rice. Among them, the bottom of the inner pot body for steaming rice is provided with a plurality of steam diversion holes, the aperture of the steam diversion holes is 1.2 mm to 2.5 mm, and the distribution density is 8 to 12 per square centimeter. At least one condensate diversion groove is opened on the inner side wall of the inner pot body, and the bottom of the diversion groove is communicated with at least one of the steam diversion holes; Referring to Figure 5 and Figure 6 , the bottom surface of the inner pot body for cooking rice noodles / noodles is set as a sealing surface, and inclined guiding holes are uniformly opened at the connection between the bottom surface and the side surface of the inner pot body. The inclined guiding holes form an inclined angle of 25° to 35° with respect to the tangent direction of the inner pot body side wall; the inclined guiding holes form an upward inclination angle of 15° to 20° with respect to the horizontal plane. When the inner pot body sinks into the water, water enters the inner pot body through the inclined guiding holes, forming a rotating water flow, so that the noodles or rice noodles in the inner pot body rotate; The diameter of the inlet of the inclined guiding hole is larger than the middle diameter, and the diameter of the outlet is larger than the middle diameter. Ensure that the water flow enters the inner pot body in the best state, produce an ideal rotating effect, make the noodles evenly stressed and fully tumble, and effectively prevent adhesion.

[0032] The device further includes a temperature sensor and a water level sensor, both electrically connected to the control module. The temperature sensor is used to detect the temperature of the liquid in the outer pot body 21, and the water level sensor is used to detect the water level of the liquid in the outer pot body 21. The control module adjusts the heating power of the electric heating component 3 and / or the motion parameters of the lifting drive mechanism 4 according to the sensor feedback signal. When the water level sensor detects that the water level exceeds the preset safety range or the temperature sensor detects that the temperature reaches the preset critical value, the control module will adjust the heating power of the electric heating component 3 or stop heating to ensure the safe operation of the device.

[0033] The device is also equipped with a wireless communication module for establishing a wireless connection with a mobile terminal device. The control module is configured with a remote control program that allows users to select a cooking mode, set cooking parameters, and monitor the cooking progress through the mobile terminal device.

[0034] The control module is configured with a cooking mode control program based on an adaptive algorithm, including: Instant rice mode Control the lifting drive mechanism 4 to move the inner pot body 22 to the first working position; Control the electric heating component 3 to output power in a pulsed or segmented manner to generate and maintain steam in the steam chamber 23.

[0035] Pulsed power output means that the electric heating component 3 alternately turns on and off at a preset time interval, for example, turns on for 10 seconds and then turns off for 5 seconds, and so on in a cycle. Segmented power output means that the electric heating component 3 adjusts the output power according to the cooking stage, such as high power for rapid heating in the initial stage, medium power to maintain steam in the middle stage, and low power for heat preservation in the final stage.

[0036] The control module integrates a compensation program module. When detecting or receiving a signal indicating that the current ambient air pressure is lower than the preset standard value (such as standard atmospheric pressure), in the operation sequence of the instant rice mode, extend the time for the electric heating component 3 to generate and maintain steam, and / or increase the output power of the electric heating component 3. This is particularly useful for users in high-altitude areas because the air pressure is low in high-altitude areas, the boiling point of water decreases, resulting in a decrease in steam temperature and affecting the cooking effect.

[0037] Rice noodle / noodle mode Control the lifting drive mechanism 4 to move the inner pot body 22 to the second working position; Control the electric heating component 3 to heat the liquid in the outer pot body 21; Control the lifting drive mechanism 4 to make the inner pot body 22 perform a periodic lifting motion.

[0038] The periodic lifting motion includes lifting the inner pot body from H to H every T to T N seconds by H to H iCentimeters and hold for 1 to 3 seconds. This periodic lifting motion helps to cook the rice noodles / noodles evenly and prevent sticking.

[0039] In the rice noodles / noodles mode, the periodic lifting motion performed by the inner pot body 22 can be divided into two stages: Within a preset initial time period T1 (such as the first 3 minutes) after the start of the mode program, control the lifting drive mechanism 4 to drive the inner pot body 22 to lift and lower at a first frequency F1 (such as once every 8 seconds), and the amplitude of each lift and lower is H1 centimeters (such as 5 centimeters); After the preset initial time period T1 ends, within the subsequent time period T2 (such as the next 5 minutes) until the end of the mode program, control the lifting drive mechanism 4 to drive the inner pot body 22 to lift and lower at a second frequency F2 (such as once every 15 seconds), and the amplitude of each lift and lower is H2 centimeters (such as 3 centimeters).

[0040] During the cooking stage of the rice noodles / noodles mode, the control module differentially adjusts the heating intensity of each partition heating unit based on the feedback signal of the temperature sensor, so that the liquid temperature in the central area of the outer pot body 21 is 2°C to 5°C higher than the liquid temperature in the surrounding area, which helps to cook the ingredients evenly.

[0041] Combined cooking mode The control module is also configured with a combined cooking mode, which combines two cooking methods: boiling and steaming: First, pre-cook the ingredients in the inner pot body 22 at the second working position for a preset T3 minutes (such as 2 minutes); Then control the lifting drive mechanism 4 to raise the inner pot body 22 to the first working position, and steam the ingredients through the steam in the steam cavity 23 for a preset T4 minutes (such as 5 minutes).

[0042] The control module integrates a compensation program module, and the compensation program module is configured to, when detecting or receiving a signal indicating that the current ambient air pressure is lower than a preset standard value, in the operation sequence of the instant rice mode, extend the time for the electric heating component to generate and maintain steam, and / or increase the output power of the electric heating component.

[0043] This application also discloses a multi-purpose convenient cooking method for instant rice, rice noodles, and noodles, including the following steps: S1: According to the selected ingredient type, start the corresponding preset cooking mode program; S2: If the instant rice mode program is started, then execute: Control the lifting drive mechanism 4 to move the inner pot body 22 to the first working position, so that a steam cavity 23 with a preset height is formed between the bottom of the inner pot body 22 and the bottom of the outer pot body 21; Control the electric heating component 3 to output power in a pulsed or segmented manner, heating the water in the outer pot body 21 to generate and maintain steam in the steam chamber 23; S3: If the rice noodle / noodle mode program is started, then execute: Control the lifting drive mechanism 4 to move the inner pot body 22 to the second working position, so that at least a part of the inner pot body 22 sinks into the liquid contained in the outer pot body 21; Control the electric heating component 3 to heat the liquid in the outer pot body 21; Control the lifting drive mechanism 4 to make the inner pot body 22 perform a periodic lifting motion, and the periodic lifting motion includes lifting the inner pot body H to H+J centimeters every T to T+N seconds and maintaining for 1 to 3 seconds.

[0044] In step S3 of the rice noodle / noodle mode program, the periodic lifting motion performed by the inner pot body includes: Within a preset initial time period T1 after the start of this mode program, control the lifting drive mechanism to drive the inner pot body to lift and lower at a first frequency F1, and the amplitude of each lift and lower is H1 centimeters; After the preset initial time period T1 ends, within a subsequent time period T2 until the end of this mode program, control the lifting drive mechanism to drive the inner pot body to lift and lower at a second frequency F2, and the amplitude of each lift and lower is H2 centimeters.

[0045] The control module is also configured with a combined cooking mode, and this combined cooking mode includes: First, perform a pre-cooking process on the ingredients in the inner pot body at the second working position, and the cooking time is a preset T3 minutes; Then control the lifting drive mechanism to lift the inner pot body to the first working position, and steam the ingredients through the steam in the steam chamber, and the steaming time is a preset T4 minutes.

[0046] Example 1: Instant rice mode Put 200g of pre-soaked rice into the inner pot body 22 for steaming rice, and add 500ml of water to the outer pot body 21. After starting the instant rice mode, the control module controls the lifting drive mechanism 4 to move the inner pot body 22 to the first working position, so that a steam chamber 23 with a height of 2.5 cm is formed between the bottom of the inner pot body 22 and the bottom of the outer pot body 21.

[0047] The control module controls the electric heating component 3 to output power in a pulsed manner (on for 10 seconds, off for 5 seconds) to heat the water in the outer pot body 21, generating steam in the steam chamber 23. The steam enters the inner pot body 22 through the steam diversion holes 221 (hole diameter 2.0 mm, 10 per square centimeter) at the bottom of the inner pot body 22 to steam the rice. The condensed water on the inner side wall of the inner pot body 22 flows back to the steam chamber 23 through the condensed water diversion groove 222, improving the water resource utilization efficiency.

[0048] When the temperature sensor detects that the steam temperature reaches 100 °C, the control module reduces the power of the electric heating component 3 by 30% to maintain a stable steam supply. The entire cooking process lasts for 15 minutes and automatically enters the heat preservation state after completion.

[0049] If it is detected that the current ambient air pressure is 85 kPa (equivalent to an altitude of about 1500 meters), the compensation program module will automatically extend the steam maintenance time by 2 minutes and increase the output power of the electric heating component 3 by 10% to compensate for the influence of the reduced steam temperature in the low air pressure environment.

[0050] Embodiment 2: Rice noodle / noodle mode Put 150 g of dry noodles into the inner pot body 22 for cooking rice noodles / noodles, and add 1200 ml of water to the outer pot body 21. After starting the rice noodle / noodle mode, the control module controls the lifting drive mechanism 4 to move the inner pot body 22 to the second working position, so that the bottom of the inner pot body 22 is immersed in the water by about 1 cm.

[0051] The control module controls the differential heating of the zoning heating unit of the electric heating component 3, so that the water temperature in the central area of the outer pot body 21 reaches 98 °C, and the water temperature in the surrounding area is maintained at 95 °C. When the water boils, the control module controls the lifting drive mechanism 4 to make the inner pot body 22 perform a periodic lifting and lowering motion: In the first 3 minutes (T1), the inner pot body 22 moves up and down at a frequency of F1 = once every 8 seconds, with each lifting and lowering amplitude of H1 = 5 cm, and stays at the vertex position for 2 seconds; In the next 5 minutes (T2), the inner pot body 22 moves up and down at a frequency of F2 = once every 15 seconds, with each lifting and lowering amplitude of H2 = 3 cm, and stays at the vertex position for 1 second.

[0052] This periodic lifting and lowering motion ensures that the noodles are evenly heated and do not stick together. The entire cooking process lasts for 8 minutes and automatically stops heating after completion.

[0053] Embodiment 3: Combined cooking mode Put 200 g of glutinous rice balls into the inner pot body 22 for steaming rice, and add 800 ml of water to the outer pot body 21. After starting the combined cooking mode, the control module first controls the lifting drive mechanism 4 to move the inner pot body 22 to the second working position, so that the bottom of the inner pot body 22 is immersed in the water by about 2 cm for pre-cooking, and the cooking time T3 = 2 minutes. In this stage, the control module controls the electric heating component 3 to output heat at 80% power.

[0054] After the pre-cooking stage ends, the control module controls the lifting drive mechanism 4 to raise the inner pot body 22 to the first working position, forming a steam chamber 23 with a height of 2.8 cm. At this time, the control module controls the electric heating component 3 to output power in a pulsed manner (on for 12 seconds and off for 6 seconds) to heat the water in the outer pot body 21, and steam in the steam chamber 23 is used to steam the glutinous rice dough. The steaming time T4 = 5 minutes.

[0055] This combined cooking method can make the glutinous rice dough not only maintain a soft and glutinous texture but also be fully cooked, avoiding the problems of a hard center or an overly soft surface that may be caused by simple steaming or boiling. The entire cooking process lasts for 7 minutes and automatically enters the heat preservation state after completion.

[0056] Example 4: Instant rice mode in high-altitude environment In an area at an altitude of 3000 meters (atmospheric pressure is about 70 kPa), 180 g of pre-soaked rice is placed in the inner pot body 22 for steaming rice, and 550 ml of water is added to the outer pot body 21. After starting the instant rice mode, the control module first obtains the air pressure information of the current location through the wireless communication module or measures the current ambient air pressure through a built-in air pressure sensor (not shown in the figure).

[0057] After detecting that the current air pressure is lower than the preset standard value, the compensation program module automatically adjusts the cooking parameters: extends the steam maintenance time from the standard 15 minutes to 19 minutes, and increases the output power of the electric heating component 3 by 15%. At the same time, the control module reduces the interval time of the pulsed power output (on for 8 seconds and off for 3 seconds) to ensure that sufficient steam density and temperature can be maintained in the steam chamber 23.

[0058] This adaptive adjustment compensates for the influence of the decrease in the boiling point of water in the high-altitude environment (about 88 °C), ensuring that the rice can be fully steamed and has a good taste. The entire cooking process lasts for 19 minutes and automatically enters the heat preservation state after completion.

[0059] Example 5: Cooking example of rice noodles 200 g of dried rice noodles are placed in the inner pot body 22 for cooking rice noodles / noodles, and 1300 ml of water is added to the outer pot body 21. After starting the rice noodles / noodles mode, the control module controls the lifting drive mechanism 4 to move the inner pot body 22 to the second working position, so that the bottom of the inner pot body 22 is immersed in water by about 1.5 cm.

[0060] The control module controls the zoned heating unit of the electric heating component 3 to heat differentially, so that the water temperature in the central area of the outer pot body 21 reaches 96 °C, and the water temperature in the surrounding area is maintained at 92 °C. This temperature difference helps the rice noodles to be heated evenly without breaking. When the water temperature reaches the set value, the control module controls the lifting drive mechanism 4 to make the inner pot body 22 perform a periodic lifting motion: In the first 2 minutes (T1), the inner pot body 22 moves up and down at a frequency of F1 = once every 10 seconds, with each lifting amplitude of H1 = 4 cm, and stays at the vertex position for 2.5 seconds; In the subsequent 4 minutes (T2), the inner pot body 22 moves up and down at a frequency of F2 = once every 18 seconds, with each lifting amplitude of H2 = 2.5 cm, and stays at the vertex position for 1.5 seconds.

[0061] The water level sensor continuously monitors the water level in the outer pot body 21. When the water level is lower than the safety water level line, the control module will issue an alarm to remind the user to add water. At the same time, the temperature sensor monitors the water temperature change to ensure that the water temperature is maintained within an appropriate range. The entire cooking process lasts for 6 minutes. After completion, the heating automatically stops, and a cooking completion notification is sent to the user's mobile terminal through the wireless communication module.

[0062] The workflow executed by the control module includes the following key steps: Initialization: After the device is powered on, the control module performs self-check, checks the working status of each component, and initializes the parameter settings.

[0063] Mode selection: The user selects the cooking mode (instant rice mode, rice noodle / noodle mode, or combined cooking mode) through the control panel or the mobile terminal application, and can adjust the cooking parameters as needed.

[0064] Environmental detection: The control module obtains environmental parameters (such as air pressure, ambient temperature, etc.) through the connected sensors or through the wireless communication module to prepare for subsequent adaptive control.

[0065] For the instant rice mode: Control the inner pot body 22 to move to the first working position, and control the electric heating component 3 to generate steam for steaming; For the rice noodle / noodle mode: Control the inner pot body 22 to move to the second working position, control the electric heating component 3 to heat the water, and drive the inner pot body 22 to perform periodic lifting and lowering movements; For the combined cooking mode: First perform pre-boiling at the second working position, and then perform steaming at the first working position.

[0066] The control module continuously monitors the cooking status through the temperature sensor and the water level sensor, and dynamically adjusts the output power of the electric heating component 3 and the motion parameters of the lifting drive mechanism 4 according to the feedback signal.

[0067] When an abnormal situation (such as too low water level, too high temperature) is detected, the control module automatically adjusts or interrupts the cooking process to ensure safety.

[0068] After cooking is completed, the control module issues a sound prompt and can send a notification to the user's mobile terminal through the wireless communication module.

[0069] According to the selected mode, it can automatically enter the heat preservation state or the standby state after cooking is completed.

[0070] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent in such process, method, article or device.

[0071] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
