[0066] The definitions of various terms or methods used in the following embodiments are, except where logically impossible, generally defined as broad concepts that can be implemented under the premise of the content disclosed in the embodiments. Under this understanding, all specific subordinate limitations of the terms or methods should be considered as part of the invention, and should not be narrowly interpreted or biased simply because the specification does not disclose such a specific limitation. For example, when the present invention refers to a control system, it includes not only virtual network servers but also real physical devices, which not only have data storage capabilities but also data processing, intelligent analysis, and reasoning capabilities. Similarly, provided logically feasible, the order of steps in the method is flexible and varied; all specific subordinate limitations within the broad concepts of various terms or methods fall within the scope of protection of this invention.

[0067] First embodiment:

[0068] Please refer to Figures 1 to 6 As shown, this embodiment proposes a control method for a sous vide cooker, including S11-S13, wherein:

[0069] S11. Obtain first water temperature data at multiple points of the low-temperature slow cooker, wherein the multiple points are located at the outlet of the corresponding circulating water pump.

[0070] This embodiment has multiple detection points in the container. Compared with the existing sous-vide makers which only have a single circulation pump and a single detection point, it has better temperature measurement effect and more accurate temperature control. In order to make the detection points more accurate and reliable, the temperature sensor is set at the outlet of the circulation pump, so that the measured temperature data is more accurate.

[0071] As a preferred option rather than a specific limitation, multiple of the aforementioned points are located on the pipes connected to the circulating water pump. By detecting the water temperature inside the connecting pipes, the detection results are made more accurate, and the heat exchange efficiency between the food and the water is higher.

[0072] As a preferred option rather than a specific limitation, step S11 includes S111-S112, wherein:

[0073] S111. Based on the real-time position of the ingredients in the container, determine multiple sites corresponding to the ingredients.

[0074] This embodiment uses a position sensor, such as a photoelectric sensor, to detect the real-time position of the food in the container. Based on the tumbling of the food in the slow cooker, the water temperature around the food is re-determined, which can more effectively adjust the heat exchange efficiency between the food and the water. For example, small ingredients such as braised eggs will float on the water surface during the steaming process. After detecting the position of the food, the corresponding circulation pump is controlled to output water according to its position in the container. The heat exchange efficiency is better than that of the existing single circulation pump, and the cooked food tastes better.

[0075] S112. Obtain the first water temperature data of the multiple sites.

[0076] Based on the identified multiple locations, temperature sensors, such as thermocouples, are used to detect the data at each location. By detecting the temperature data at multiple locations, the detected data is more accurate and can provide better assistance in subsequent control, thereby promoting heat exchange between the food and water.

[0077] As a preferred option rather than a specific limitation, step S112 includes S1121-S1123, wherein:

[0078] S1121. Obtain the second water temperature data of the sous-vide cooker within a unit cycle.

[0079] In this embodiment, the second water temperature data is acquired multiple times within a predetermined unit period. The unit period can be divided into multiple parts based on the different heating times of the ingredients. For example, if the ingredients are cooked for twelve hours, the twelve hours can be divided into 1,200 parts. The system then checks once every 36 seconds. The second water temperature data is a data set acquired multiple times within the above-mentioned period, and this data set includes data sets from multiple locations, thereby making the acquired temperature data more accurate.

[0080] S1122. Filter the second water temperature data based on the filtering algorithm to generate the third water temperature data.

[0081] This embodiment uses a filtering algorithm to filter the previously collected second water temperature data, removing invalid, excessively high peak data, or excessively low trough data, making the measurement results more accurate and better eliminating external influences on the data, thus generating third temperature data. The filtering algorithm performs the first filtering selection using the Pearson correlation coefficient, and then performs a second filtering screening using the chi-square distribution, calculating the chi-square metric distribution between the target and the numerical variable, selecting only the variable with the largest chi-square value, and finally determining the required data through recursive feature elimination, making the filtering process more accurate.

[0082] S1123. Determine the first water temperature data based on the third water temperature data.

[0083] In this embodiment, the temperature data is reorganized and sorted using the third water temperature data selected above, and the mean, median and mode of the third water temperature data are taken according to preset rules. The three data are analyzed to determine the first water temperature data. The preset rules are calculated based on the calculation library stored in the control system.

[0084] S12. Determine the optimal water flow rate at each point based on the first water temperature data and the preset optimal cooking temperature.

[0085] This embodiment retrieves the optimal cooking temperature for the corresponding ingredients from the control system, compares it with the first water temperature data, and then calculates the water flow rate corresponding to the water temperature. This ensures that the water temperature output from the circulating water pump outlet matches the optimal temperature required by the ingredients, thereby making the cooked ingredients taste better, have higher nutritional value, and improve the heat exchange efficiency between the ingredients and water.

[0086] As a preferred option rather than a specific limitation, step S12 includes S121-S123, wherein:

[0087] S121. Obtain the optimal cooking temperature for the corresponding ingredients.

[0088] In this embodiment, after the corresponding food type and name are automatically detected by machine vision or manually input, the corresponding food data is retrieved from the storage database of the control system to determine the optimal cooking temperature of the food. This allows for better control of the machine output temperature, resulting in better taste and nutritional value of the cooked food.

[0089] S122. Based on the comparison algorithm, compare the first water temperature data with the optimal cooking temperature of the corresponding ingredients to determine the first temperature difference.

[0090] In this embodiment, the optimal cooking temperature of the corresponding ingredient is determined and compared with the first water temperature data based on a comparison algorithm. The value obtained from the comparison is determined as the first temperature difference. The comparison algorithm determines the result by performing distance analysis on the data and the position of the data on the coordinate axis, so that the determined result is more accurate and the comparison efficiency is higher.

[0091] S123. Determine the optimal water flow velocity at each point based on the first temperature difference.

[0092] This embodiment determines the difference between the water temperature and the optimal cooking temperature by using a first temperature difference value. The temperature value is adjusted by controlling the water flow speed. When the water flow speed is slower, the heat exchange between the water and the food is more sufficient, and the temperature value transferred is higher. When the water flow speed is faster, the heat exchange between the water and the food is less sufficient, and the temperature value transferred is lower. This adjusts the water temperature and thus affects the heat exchange between the food and the water.

[0093] As a preferred option rather than a specific limitation, step S123 includes S1231-S1232, wherein:

[0094] S1231. Based on the first temperature difference, establish the maximum heat flux equation for the flow heat transfer process.

[0095] In this embodiment, the first temperature difference is determined and set as the heat flux parameter. The flow process is set as a mathematical model, and the water flow heat transfer process is a three-dimensional steady-state turbulent process. Boundary condition values ​​are set to solve the model, thereby achieving precise temperature control.

[0096] S1232. Based on the maximum heat flux equation, generate the optimal water flow velocity at each point.

[0097] This embodiment establishes continuity equations, momentum conservation equations, and energy conservation equations, substitutes heat flux parameters into the maximum heat flux equation, and combines these equations to obtain the temperature value. Then, through the transformation of the temperature value and the water flow velocity formula, the precise optimal water flow velocity is finally obtained, resulting in better control.

[0098] S13. Determine the operating rate of the circulating water pump at each point based on the optimal water flow velocity.

[0099] This embodiment determines the water flow velocity at each point by establishing the optimal water flow velocity. Once the water flow velocity is determined, the operating rate of the circulating water pump is also determined. By using the optimal water flow velocity to determine the operating rate of the circulating water pump at each point, the operation is more stable and the control is more precise.

[0100] As a preferred option rather than a specific limitation, step S13 includes S131-S132, wherein:

[0101] S131. Obtain the water volume in the pipeline between two different locations, wherein the pipeline is located at the outlet and inlet of the corresponding circulating water pump.

[0102] In this embodiment, pipes are installed at the outlet and inlet of the corresponding circulating water pump to assist the circulating water pump in heating and outputting water, while transporting the water to the location where heat exchange is required. The circulating water pumps are installed at multiple locations on the container, which can be equally spaced along the axial direction of the container and equally spaced along the circumference of the container to improve the circulation effect and increase the heat exchange efficiency.

[0103] As a preferred option rather than a specific limitation, the pipeline is located between two circulating water pumps at different locations, connecting the outlet of the first water pump to the inlet of the second water pump. By diverting a portion of the water from the outlet of the first water pump to the container, and the other portion flowing through the pipeline to the inlet of the second water pump, the water is heated and circulated by the circulating water pump to rapidly heat up the sous-vide cooker.

[0104] S132. Determine the operating rate of the circulating water pump at each point based on the water volume in the pipeline and the optimal water flow velocity.

[0105] This embodiment determines the required temperature for the machine to heat up by measuring the water flow in the pipeline, so that the temperature reaches a suitable threshold. It also allows for better control of the operating speed of the circulating water pump, preventing excessive pressure due to the pump running too fast or water shortage in the pipeline due to the pump running too slow. Combined with the optimal water flow rate, it can better ensure that the water temperature in the container remains at a high level of stability.

[0106] This embodiment obtains the first water temperature data at multiple points located at the corresponding outlets of the circulating water pump, and then combines it with the preset optimal cooking temperature to determine the optimal water flow rate at each point, thereby determining the operating rate of the circulating water pump at each point. This solves the problem of poor heat exchange efficiency between food and water during the cooking process, which leads to uneven heating of some food and resulting in half-cooked food. It also makes the cooked food more nutritious.
