Description

Technical Field

[0001] The invention belongs to the technical field of intelligent slow cookers, and in particular relates to a slow cooker with intelligent temperature control. Background Art

[0002] Slow cookers are a common kitchen appliance, usually used to cook foods that require long, low-temperature slow cooking, such as soups, stews, etc. Most slow cookers have multiple cooking modes, such as low, medium, high, and keep warm. Choosing the right cooking mode is very important because different foods require different cooking temperatures and times. Generally speaking, slow cooking at low temperatures can better preserve the nutrition and taste of food, while also achieving energy-saving effects.

[0003] Slow cookers differ from other electric cookers in function, power and usage. Slow cookers are more suitable for long-term, low-temperature slow cooking of food, while other electric cookers such as electric hot pots and electric pressure cookers are more suitable for quick cooking and a variety of cooking needs. When cooking ingredients, the ingredients will release moisture when heated. At the same time, the steam in the slow cooker will condense into moisture, which will be absorbed by the ingredients or remain in the pot. Therefore, as the cooking time increases, the moisture in the pot will gradually decrease;

[0004] Many slow cookers allow users to preset cooking times. Generally, slow cookers include heating mode and keep warm mode. By setting the heating time, once the preset cooking time is reached, the slow cooker will automatically switch from heating mode to keep warm mode. This method is simple and direct, but not flexible enough, because different ingredients and cooking needs require different cooking times. The set time is fixed, but different ingredients require different cooking times. If the food that needs to spend less time to reach the cooking requirements enters the keep warm mode after the initial set time, it will not only waste energy, but may also cause problems with poor taste.

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] like Figure 1-Figure 3 As shown, a slow cooker with intelligent temperature control includes a pot body, a central processing module, a communication module and a light wave detection module; the pot body includes an outer shell 1, an inner pot 2 and a pot cover 3, the inner pot 2 is installed in the outer shell 1, and the pot cover 3 covers the inner pot 2; the light wave detection module is arranged on the pot cover 3; the light wave detection module includes a light wave sensor 7 and a light wave comparison unit, the light wave sensor 7 is used to transmit waves to food stewed in the inner pot 2, and receive the wavelength reflected after the food absorbs the waves, and the light wave comparison unit is used to compare the reflected wave of the initial food and the reflected wave value after cooking, and upload the difference to the central processing module through the communication module; the central processing module compares and determines whether to control the slow cooker to enter the insulation mode according to the preset threshold value;

[0026] First, there are significant differences between raw food and cooked food in surface morphology and internal structure. The surface of raw food is relatively smooth, but after cooking, the surface of the food generally becomes rougher, with bubbles, cracks or wrinkles, etc. Therefore, before cooking begins, the light wave sensor 7 detects the reflected light wave data of raw food as a reference value. As cooking proceeds, the morphology of the food surface changes, and the light wave reflected by the light wave detection sensor will also change. The light wave comparison unit will track the intensity changes of the light wave reflected by the light wave detection sensor in real time, and upload the difference to the central processing module through the communication module. After the central processing module receives the reflected wave difference uploaded by the light wave comparison unit, it will perform comparative analysis based on the preset wavelength threshold. When the reflected wave difference reaches or exceeds the wavelength threshold, the central processing module will determine that the food has been cooked and control the slow cooker to enter the insulation mode.

[0027] The wavelength threshold is set based on the significant differences in surface morphology and internal structure between raw and cooked food. The surface of cooked food generally becomes rougher, with bubbles, cracks or wrinkles, while the surface of raw food is smooth, which is a significant difference between the two states of food. Light waves are visible waves with relatively weak penetration ability, and can be used for food detection. By analyzing the light reflected from the surface of food by visible light sensors, changes in surface roughness, bubbles, cracks or wrinkles can be detected, thereby indirectly judging the degree of cooking of food. This method is widely used in food safety testing and quality monitoring. In short, even if different foods are cooked at the same gear, targeted cooking of ingredients can be achieved. The slow cooker changes from fixed gear heating to intelligent temperature adjustment. According to the cooking process of the food, the fixed timer gear heating time ends and enters the insulation mode in advance, which reduces energy waste, makes cooking more intelligent, and has more obvious energy-saving effects. Secondly, since the ingredients are switched to insulation mode when they are nearly finished, the loss of nutrients and the decline in taste of the ingredients caused by overcooking are avoided, thereby improving the quality and efficiency of cooking.

[0028] In one embodiment, the consistency detection module is integrated into the slow cooker system to accurately detect the consistency of the food, so as to control the slow cooker to enter the insulation state at an appropriate time. The consistency detection module is installed at the bottom of the pot cover 3 to ensure that it can accurately contact the food juice. The consistency detection module is electrically connected to the central processing module by wireless means to ensure the real-time data transmission. The core components of the consistency detection module include an electric telescopic probe 4, a transmitter 5 and a receiving unit. The transmitter 5 is responsible for emitting visible light, and its light source is stable to ensure the penetration and reflectivity in the food juice. The electric telescopic probe 4 has a telescopic function and can be extended into the food to pick up the juice. When the electric telescopic probe 4 picks up the juice, the visible light emitted by the transmitter 5 will pass through the electric telescopic probe 4 and reflect back to the receiving unit. The receiving unit is preset with the refractive index of the juice when the food is not cooked, which is used for subsequent comparison with the refractive index of the juice during the cooking process. The receiving unit can receive the light reflected back by the electric telescopic probe 4 after picking up the juice in real time, and calculate the time when the refractive index of the juice is close to the standard value. When the refractive index of the juice approaches the preset standard value, the receiving unit will record the time value required to approach the standard value, and upload the time value to the central processing module; after receiving the time value, the central processing module will compare it with the preset standard time value. If the received time value reaches or exceeds the standard time value, the central processing module will determine that the food has been cooked to an appropriate consistency, and control the slow cooker to enter the insulation state to maintain the taste and temperature of the food. Through the consistency detection module of this embodiment, the slow cooker can realize intelligent detection of food consistency, improve the intelligent level of cooking, and enter the insulation mode in advance according to the degree of cooking of the food, intelligently control the temperature, and achieve energy saving effect.

[0029] In one embodiment, it also includes a pressure detection module, which is arranged on the inner pot 2, and the inner pot 2 is rotatably connected to the outer shell 1. The pressure detection module is used to detect the impact force of food impacting the inner pot 2 when the inner pot 2 rotates. The pressure detection module includes a data processing unit and a plurality of pressure sensors 6, and the plurality of pressure sensors 6 are equidistantly distributed on the inner pot 2. The plurality of pressure sensors 6 upload the detected pressure values ​​to the data processing unit, and the data processing unit compares the detected pressure data and uploads the compared average data to the central processing module. The data processing unit is electrically connected to the central processing module, and the data processing unit uploads the detected pressure value to the central processing module. The central processing module is provided with a pressure threshold, and the central processing module determines whether to control the slow cooker to enter the insulation mode according to the size of the detection value and the pressure threshold. During cooking, the inner pot 2 rotates with the outer shell 1 at a fixed time. During rotation, the ingredients cooked in the pot will rotate and act on the wall of the inner pot 2, generating an impact force on the wall of the inner pot 2. Due to cooking, the inner pot 2 rotates with the outer shell 1 at a fixed time. When rotating, the ingredients cooked in the pot will rotate and act on the wall of the inner pot 2, generating an impact force on the wall of the inner pot 2. The front inner pot 2 contains a relatively large proportion of raw ingredients and water. When it rotates, the impact force on different parts of the inner pot 2 is inconsistent. When ingredients such as meat are in a raw state, since the water in the meat itself has not been lost, a large impact force will be generated on the wall of the inner pot 2 during rotation. In addition, since some meat is accompanied by bones, the force of the bones is greater than that of the meat, resulting in a large pressure difference at different parts of the inner pot 2. After the meat is cooked and cooked, the water itself is lost, the meat becomes soft, the volume increases, and the weight becomes lighter. Furthermore, after rotation, due to the centrifugal effect on the inner pot 2, the impact force of the cooked state is weaker than that of the uncooked state, and the force at different places is more uniform. Therefore, after the data processing unit receives the data from each pressure sensor 6, it will first calculate the mean of these data to reflect the overall force of the food impacting the inner pot 2; in addition, the data processing unit needs to further analyze the degree of discreteness of the data. The judgment of the degree of discreteness can be achieved in many ways, such as calculating the standard deviation or coefficient of variation of the data. The standard deviation can reflect the degree of deviation between the data and its mean, while the coefficient of variation takes into account the relative dispersion of the data and is not affected by the data unit or the size of the mean. Through these statistics, the data processing unit can quantify the differences in the stress conditions at various positions. When the data processing unit finds that the dispersion of the data is small, that is, the stress at various positions of the inner pot 2 is relatively uniform, it can be preliminarily judged that the food has been cooked and softened.This is because the texture of cooked food is more uniform, and the impact force on the inner pot 2 will be more balanced. The data processing unit also needs to upload the calculated mean data and discrete degree data to the central processing module; the central processing module will make a comprehensive judgment based on the preset pressure threshold and discrete degree threshold. If the mean data reaches or exceeds the pressure threshold and the discrete degree data is within an acceptable range, the central processing module will determine that the food has been cooked and softened, and control the slow cooker to enter the keep-warm mode; by combining the data processing unit's analysis of the mean and discrete degree of the pressure sensor 6 data, and the central processing module's comprehensive judgment of the preset threshold, intelligent monitoring and precise control of the cooking status of food can be achieved. When the food is cooked and softened, the slow cooker will automatically enter the keep-warm mode, thereby achieving energy saving and ensuring the taste and nutritional value of the food.

[0030] In one embodiment, it also includes an energy consumption detection module, which is designed with a power sensor and a weight sensor. The power sensor collects the power consumption data of the slow cooker in real time to obtain the energy consumption generated during the cooking process of the slow cooker. The weight sensor is used to detect the weight change of the food during the cooking process; the energy consumption detection module includes a real-time consumption unit and a historical consumption unit, the real-time consumption unit and the historical consumption unit are communicated and connected, the real-time consumption unit is used to record the energy consumption and weight change data generated during the current cooking process of the slow cooker; the historical consumption unit is used to record the energy consumption data consumed when cooking foods of different weights in the past. The energy consumption detection module predicts the energy consumption according to the weight changes of the pot body and the food during the cooking process; the power sensor built into the energy consumption detection module collects the energy consumption data of the slow cooker during operation in real time. The power consumption data during the cooking process reflects the energy consumption of the slow cooker at different cooking stages and different heating powers. The real-time consumption unit is mainly responsible for recording the energy consumption data of the current slow cooker during cooking and the weight change data of the pot and food. These data provide direct feedback on the energy consumption and weight change of the current cooking cycle. The historical consumption unit is responsible for storing the energy consumption data consumed when cooking foods of different weights in the past. These data are based on past cooking experience and records, forming an energy consumption mode library for different foods and different weights under the same or different cooking modes. By integrating the data of the real-time consumption unit and the historical consumption unit, the energy consumption detection module can predict the energy consumption of the pot and food under different weight changes during the current cooking process. This prediction is based on the analysis of the current cooking state (such as temperature, humidity, power consumption, etc.) and historical data, so as to obtain a more accurate energy consumption prediction result; in short, by integrating the data of the intelligent perception module, the energy consumption detection module can further intelligently control the working state of the slow cooker. For example, when food is nearly cooked, the power can be automatically reduced or the cooker can enter the keep warm mode in advance to reduce unnecessary energy consumption. By real-time monitoring and recording the energy consumption data of the slow cooker, more accurate cooking time can be provided for different ingredients, so that adjustments can be made as needed to achieve energy-saving optimization.

[0031] In one embodiment, it also includes a heating module, which is used to provide temperature; the heating module includes a power supply unit and a heating unit, the power supply unit is used to provide power to the heating unit for the heating unit to generate heat; it also includes a safety monitoring module, the safety monitoring module is electrically connected to the central processing module, and the safety monitoring module is provided with a temperature threshold and a dryness threshold; the safety monitoring module is used to obtain the real-time temperature value and real-time humidity value of the slow cooker and compare them with the temperature threshold and the dryness threshold. If the real-time temperature value is higher than the temperature threshold or the real-time humidity value is lower than the dryness threshold, it is judged as an abnormal value, and the safety monitoring module uploads the abnormal value to the central processing module, and the central processing module sends a power-off command to the power supply unit; the power supply unit is responsible for providing the required power supply to the heating unit, so that the heating unit can generate heat, and then provide the slow cooker with the thermal energy required for cooking; the safety monitoring module is electrically connected to the central processing module , responsible for real-time monitoring of the working status of the slow cooker and setting temperature thresholds and dryness thresholds. These two thresholds are set according to the normal working conditions and safety standards of the slow cooker; the safety monitoring module obtains the current temperature and humidity values ​​of the slow cooker in real time, reflecting the internal working environment and status of the slow cooker; the safety monitoring module will compare the acquired real-time temperature and humidity values ​​with the preset temperature threshold and dryness threshold; if the real-time temperature value exceeds the temperature threshold, or the real-time humidity value is lower than the dryness threshold, this means that the slow cooker has an abnormal situation, such as overheating or dry burning; once the safety monitoring module detects an abnormal value, it will immediately upload the abnormal value to the central processing module. After receiving the abnormal value, the central processing module will immediately determine whether the current situation constitutes a safety hazard, and send a power-off command to the power supply unit for power-off protection, thereby ensuring that the safety of the slow cooker can be guaranteed during long-term cooking.

[0032] In one embodiment, the storage module is electrically connected to the heating module, and the storage module stores the gear information of the heating module, and the gear information includes low gear mode, medium gear mode and high gear mode; specifically, according to the gear mode, the following can be selected in sequence: low gear, medium gear, high gear and heat preservation gear, and the continuous cycle switching: the corresponding indicator light is on during operation; when the low gear, medium gear and high gear are selected, the corresponding gear LED light and LED display screen (06:00) are on for 0.5s and off for 0.5s. Press the key once to enter the working state, and the default time is 6H; press the START / STOP key again to enter the standby state. 4. The minimum time setting is 30MIN, and the time key (C00KTime) is accumulated in steps of 30MIN. The maximum setting time of all gears is 10 hours. The countdown is displayed during the heating process. If the low gear, medium gear and high gear are selected, the peak sounder sounds three times after the heating time is up, and then it automatically switches to the heat preservation state. The default time after switching to the heat preservation gear is 6H, and it will enter the standby state after working for 6H. 5 When low-grade heating is selected, it works for 3 minutes, power off for 1 minute, and works in a cycle. When "medium-grade med" is selected, it works for 3 minutes and 20 seconds, power off for 40 seconds, and works in a cycle. When high-grade HIG is selected, it works for 3 minutes and 50 seconds, power off for 10 seconds, and works in a cycle. When the keep warm gear is selected, it works for 1.5 minutes, power off for 2.5 minutes, and works in a cycle. After the low-grade, medium-grade and high-grade heating time is up, the buzzer sounds three times and the time is displayed as 00:00, and it automatically switches to the keep warm state.

The display interface module includes a display screen and an indicator light. The display screen is used to display information such as time and numbers.

The key interface module uses a plurality of physical keys, which are arranged on the control panel of the slow cooker to facilitate user operation. Each key corresponds to a different function, such as gear selection, start / pause, timing, etc. The user can input the gear information of the heating module by pressing the corresponding key. For example, the user can press the "low gear" key to select the low gear mode, or press the "high gear" key to select the high gear mode. The key interface module will receive the user's key input in real time and pass it to the central processing module for processing. The display interface module includes a display screen and an indicator light, which is used to output display data and show the working status and related information of the slow cooker to the user. The indicator light uses a variety of colors and flashing modes to display different states of the product. For example, when the slow cooker is in the heating state, the indicator light can light up red; when cooking is completed, the indicator light can turn green and continue to flash; after the user inputs the gear information through the key interface module, the central processing module will receive this information and process it. Then, the central processing module will send the corresponding instructions to the heating module to make it work according to the gear selected by the user. At the same time, the central processing module will also output and display the current working status and related information through the display interface module. In this way, the user can understand the working status and related information of the slow cooker in real time through the display and indicator light.
