Description

Technical Field

[0001] This invention relates to the field of milk warmer technology, and in particular to a water bath heating milk warming control method, system, device and storage medium. Background Technology

[0002] Bottle warmers are popular with consumers due to their automatic temperature regulation. However, both water bath and steam bottle warmers suffer from the problem of overheating milk if bottles are not removed promptly. Firstly, if a bottle containing liquid is placed in the warmer and not removed immediately after heating, the high water temperature and rapid heat transfer can cause overheating. Secondly, existing heating logics can result in milk temperatures that are too low or too high depending on the liquid's state. In short, current bottle warmer technologies cannot achieve precise temperature control, leading to overheating and negatively impacting the consumer experience. Summary of the Invention

[0051] The embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. The step numbers in the following embodiments are set only for ease of explanation, and there is no limitation on the order between the steps. The execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0052] Existing bottle warmers, whether water-bath or steam-type, suffer from the problem of overheated milk if bottles are not removed promptly. Firstly, if a bottle containing liquid is placed in the warmer and not removed immediately after heating, the high water temperature in the tank leads to rapid heat transfer and overheating. Secondly, the machine cannot distinguish between refrigerated and room temperature milk, using the same heating logic, resulting in milk temperatures that are either too low or too high. Milk that is too hot or too cold after heating is unsuitable for infants / children. Understandably, milk exceeding 42℃ can degrade the quality of dairy products, while milk that is too cold can cause digestive problems or lead to infants / children refusing to drink it. The heating logic of commonly used bottle warmers on the market is to heat the water in the tank at full power to maintain a high temperature. Once the milk temperature in the bottle reaches 37°C, the entire machine shuts off and the heating plate stops working. This means that if the bottle isn't removed promptly, the milk temperature can quickly rise to over 42°C within 20 seconds due to heat transfer. Secondly, most products provide two tables in the instruction manual to differentiate between heating room temperature and refrigerated milk. Consumers manually adjust the heating time according to the tables, but the internal heating logic is the same for all, making it impossible to set different heating logics based on the bottle material and capacity. Furthermore, the manual input process is cumbersome and lacks automation. Finally, the milk temperature inside the bottle is inaccurate. Therefore, the shortcomings of this technology are as follows: If the bottle isn't removed promptly after heating, the high water temperature in the tank leads to rapid heat transfer and overheating of the liquid inside the bottle; it cannot automatically distinguish between refrigerated and room temperature milk, and it cannot set different heating logics based on different materials and capacities, resulting in milk temperatures that are too high or too low. To address the aforementioned issues, this invention provides a bottle warmer control scheme that automatically identifies refrigerated and room temperature milk, and sets different heating logics based on different bottle materials and contents, thereby making the bottle warmer heat the milk more accurately.

[0053] The following describes in detail the water bath heating milk warming control method and system according to the embodiments of the present invention with reference to the accompanying drawings. First, the water bath heating milk warming control method according to the embodiments of the present invention will be described with reference to the accompanying drawings.

[0054] Reference Figure 1This invention provides a water bath heating milk warming control method. This method can be applied to a terminal, a server, or software running on either a terminal or server. The terminal can be a tablet, laptop, desktop computer, etc., but is not limited to these. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. The water bath heating milk warming control method in this invention is used in a milk warmer, and the method mainly includes the following steps:

[0055] S100: Obtain the bottle material and bottle capacity;

[0056] S200: Receives a milk warming command, starts milk shaking, and acquires several first temperatures, the first temperatures being used to characterize the temperature of the water in the milk warmer's water tank;

[0057] S300: Determine the liquid state of the liquid in the bottle based on the change in the first temperature; the liquid state includes refrigerated state or room temperature state;

[0058] S400: Based on the liquid state, the bottle material, and the bottle capacity, a temperature adjustment strategy is used to determine the warming temperature and countdown time; the warming temperature is used to characterize the temperature of the water bath in the bottle warmer used for heat transfer of the liquid.

[0059] S500: Perform milk shaking and heating according to the stated temperature and the stated countdown time.

[0060] In some possible implementations, the water bath in this application embodiment is used to characterize the water in the bottle warmer's water tank. It is understood that this application embodiment first obtains the bottle material and bottle capacity. For example, when a consumer places a bottle into the bottle warmer, this application embodiment can determine the bottle capacity by the water level in the bottle warmer's water tank; alternatively, a relevant input unit can be provided on the bottle warmer's outer casing to determine the bottle capacity through consumer input or selection. This application embodiment does not limit the specific method of obtaining the bottle capacity. Similarly, the bottle material in this application embodiment can be automatically detected by examining the material of the placed bottle, or it can be obtained through consumer input. The warming instruction in this application embodiment is used to characterize the consumer's input instruction to start heating. During a period of heating, only shaking is activated, and several first temperatures are collected in real time. The first temperatures in this application embodiment are used to characterize the water temperature in the bottle warmer's water tank. This application embodiment determines the liquid state of the liquid in the bottle by detecting the temperature change of the water in the tank after the bottle is placed in, so that heating logic can be set according to different liquid states subsequently. It should be noted that the refrigerated state in this application embodiment includes refrigerated liquid or frozen liquid. It is understood that when the liquid in the bottle is refrigerated, there is a heat transfer process to the water in the bottle warmer tank, causing the temperature change of the water in the bottle warmer tank to differ from that at room temperature. Furthermore, this application embodiment employs different heating logics for refrigerated liquid and liquid at room temperature to achieve precise temperature control.

[0061] In some possible implementations, the control process provided in this application embodiment is as follows: The consumer puts in the bottle, and the machine panel can select the bottle material (glass, plastic, silicone) and bottle capacity (exemplarily, 2-8oz). After selection, the machine enters the heating working state and starts the heating function. The machine first automatically identifies whether the milk is refrigerated or at room temperature through a 15-second scrolling light. After determining the temperature, it automatically enters different heating temperatures and heating time countdowns based on different materials and capacities. The heating temperature refers to the temperature of the water in the bottle warmer's tank used for warming the milk. After the water reaches the heating temperature, the heating plate stops heating. The subsequent heating of the liquid in the bottle relies on heat transfer from the water in the tank to raise the temperature of the milk in the bottle. This ensures that after the heating program ends, if the bottle is not removed immediately after turning off, the temperature will not rise above 42°C for 3 minutes. For most materials and capacities, the milk in the bottle will remain below 42°C and will only gradually cool down. The milk in the bottle will not reach 42°C, which helps to alleviate the problem of excessively high liquid temperature in the bottle.

[0062] Secondly, regarding the process of determining whether the milk is refrigerated or at room temperature, this bottle warmer is a shaker-type bottle warmer. During operation, it heats and shakes the milk simultaneously. During the 15-second judgment period, it only shakes the milk without heating. Because the water tank is heated differently for refrigerated and room temperature milk, the water temperature in the tank can be uniformly and quickly transferred while shaking the milk, resulting in a significant change in the AD value (i.e., the temperature change of the water in the tank). The NTC sensor in the tank detects the magnitude of this AD value change, which indicates the milk is refrigerated or at room temperature, thus determining whether it is refrigerated or room temperature milk. After the 15-second scrolling indicator completes the judgment, the screen begins the program's default heating time countdown, simultaneously heating and shaking the milk to promote rapid and uniform heating.

[0063] In this embodiment of the application, the AD value changes significantly during the milk shaking process, thus automatically identifying refrigerated and room temperature milk. Based on the identified refrigerated and room temperature states, milk of different materials and capacities can be precisely heated, and different heating logic can be set to prevent overheating.

[0064] Optionally, in one embodiment of the present invention, receiving the milk warming command, starting the milk shaking, and obtaining several first temperatures includes:

[0065] Receive the milk warming instruction and obtain the first accumulated time;

[0066] Several first temperatures are obtained between a first moment and a second moment, and averaged to determine a first value; the first moment is used to characterize the moment when the first cumulative duration is a first duration, the second moment is used to characterize the moment when the first cumulative duration is a second duration, and the second duration is greater than the first duration;

[0067] Several first temperatures are obtained between the third and fourth time points, and averaged to determine a second value; the third time point is used to characterize the moment when the first cumulative duration is the third duration, the fourth time point is used to characterize the moment when the first cumulative duration is the fourth duration, the third duration is greater than the second duration, and the fourth duration is greater than the third duration;

[0068] Several first temperatures are obtained between the fifth and sixth time points, and averaged to determine a third value; the fifth time point is used to characterize the moment when the first cumulative duration is the fifth duration, the sixth time point is used to characterize the moment when the first cumulative duration is the sixth duration, the fifth duration is greater than the fourth duration, and the sixth duration is greater than the fifth duration.

[0069] In some possible implementations, refer to Figure 2In one embodiment shown, after the milk warming process is initiated, a timer is started to acquire a first cumulative duration. This first cumulative duration represents the elapsed time since the milk warming command was received. It is understood that this embodiment can collect first temperatures at different time intervals and determine the changes in the first temperature based on these different temperatures. For example, if the first duration is 0 seconds and the second duration is 1 second, then several first temperatures are acquired between the first cumulative duration and the second duration, i.e., multiple first temperatures are acquired between 0 seconds after receiving the milk warming command and 1 second after receiving the milk warming command, and the average is taken to obtain a first value. Similarly, the third duration is 4 seconds, the fourth duration is 5 seconds, the fifth duration is 10 seconds, and the sixth duration is 15 seconds. It is understood that, for... Figure 2 In the illustrated embodiment, the first moment is 0 seconds from the start of receiving the milk warming command, the second moment is 1 second from the start of receiving the milk warming command, the third moment is 4 seconds from the start of receiving the milk warming command, the fourth moment is 5 seconds from the start of receiving the milk warming command, the fifth moment is 10 seconds from the start of receiving the milk warming command, and the sixth moment is 15 seconds from the start of receiving the milk warming command. Specifically, the multiple first temperatures within 1 second of receiving the milk warming command are averaged, and the multiple first temperatures within 5 seconds can be averaged in intervals, and then the maximum value is taken. See details. Figure 2 The acquisition process shown is specifically as follows: Step 1, take an ad value every 0.01s; Step 2, take the average of the 10 ad values ​​taken in Step 1 as the ad value every 0.1s; Step 3, take the sum of the 10 ad values ​​taken in Step 2 as the ad value every 1s. For example, the ad values ​​for 0-1s and 4-5s can be determined using the value acquisition logic in Steps 1 to 3 above, and the ad values ​​for 0-1s are used as the 1s value in Table 1; the ad values ​​for 4-5s are used as the 5s value in Table 1. Then, using the value acquisition logic in Steps 1 to 3 above, the ad values ​​for 10-11s, 11-12s, 12-13s, 13-14s, and 14-15s are determined, resulting in several ad values. The maximum value is then taken as the 15s value in Table 1. Therefore, the judgment logic for determining the liquid state of the liquid in the bottle based on the change of the first temperature provided in this application embodiment includes the following steps:

[0070] Receive the milk warming command, obtain several first temperatures within the first time period, average the several first temperatures by time period, perform a summation operation, and determine the first value within the first time period.

[0071] Obtain several first temperatures within the second time period, average these first temperatures across different time periods, and then sum them up to determine the second value within the second time period.

[0072] Several first temperatures within the third time period are obtained. After averaging these first temperatures across different time periods, summation and extreme value operations are performed to determine the third value within the third time period. The third time period is after the second time period, and the second time period is after the first time period.

[0073] Of course, the specific values ​​for each of the above durations are merely illustrative examples. Those skilled in the art can set appropriate duration values ​​based on the usage scenario and region of the bottle warmer to accurately determine the liquid state. The specific value selection logic described above is also illustrative. Those skilled in the art can set the order of averaging, summing, and taking extreme values, and the data for each calculation logic's corresponding time period, according to actual needs. It is understood that... Figure 2 The illustrated embodiment determines the liquid state using a first, second, and third numerical value; however, those skilled in the art can also determine the liquid state using multiple numerical values. This application does not limit the specific values ​​at the time of data collection, the specific number of first temperatures collected, or the specific number of determined values.

[0074] For example, Table 1 shows the first temperature data of multiple bottle capacities and bottle materials collected under refrigerated conditions. Table 2 shows the first temperature data of multiple bottle capacities and bottle materials collected under room temperature conditions. Here, 1S represents the first value, 5S represents the second value, and 15S represents the third value. It is understood that refrigeration typically represents a state within the range of 0 to 4 degrees Celsius, and room temperature typically represents a state around 22 degrees Celsius. Therefore, this application embodiment collects multiple first temperatures for a state of 13 to 15 degrees Celsius, as shown in Table 3 for reference. It is understood that temperatures of 13 to 15 degrees Celsius fall within the midpoint between refrigerated 4°C and room temperature 22°C. In actual use, the machine may determine that a bottle in this temperature range is refrigerated and execute the refrigerated heating mode, or it may determine that it is room temperature and execute the room temperature heating mode. However, referring to some specific embodiments shown in Table 3, regardless of which mode is used, since it is within the midpoint temperature range, the milk heated by the control method provided in this application is at a drinkable temperature and will not exceed 42°C, which can meet consumer needs. It should be noted that the first temperature given in the table is the voltage value obtained through AD acquisition, which is used to characterize the temperature of the water in the water tank of the bottle warmer.

[0080] Table 3

[0081] Optionally, in one embodiment of the present invention, the method for determining the liquid state of the liquid in the bottle based on the change in the first temperature includes:

[0082] Based on the first value and the second value, determine the first difference;

[0083] The second difference is determined based on the second value and the third value;

[0084] If the second value is less than the first value and the first difference is greater than the first threshold, the liquid state is determined to be at room temperature; or, if the third value is less than or equal to the second value, the liquid state is determined to be at room temperature.

[0085] Alternatively, if the third value is greater than the second value, the liquid state is determined based on the bottle material and the second difference.

[0086] In some possible implementations, the first difference between the first and second values ​​can be represented by Δad(1-5S), as shown in Table 1, and the second difference can be represented by Δad(5-15S). Figure 2 The specific judgment logic shown determines the liquid state. Based on... Figure 2 In the illustrated embodiment, the first threshold is set to 1. Of course, this is an exemplary example, and those skilled in the art can adjust it according to actual circumstances. It should be noted that △ad(1-5S) in Tables 1 to 3 is used to characterize ad_1s-ad_5s.

[0087] Optionally, in one embodiment of the present invention, determining the liquid state based on the bottle material and the second difference includes the following steps:

[0088] If the bottle is made of glass and the second difference is less than the second threshold, the liquid is determined to be in a room temperature state.

[0089] Alternatively, if the bottle is made of plastic and the second difference is less than the third threshold, the liquid state is determined to be at room temperature; the third threshold is less than the second threshold.

[0090] Alternatively, if the bottle material is not glass, the bottle material is not plastic, and the second difference is less than the fourth threshold, the liquid state is determined to be at room temperature; the fourth threshold is less than the third threshold.

[0091] In some possible implementations, based on Figure 2In one embodiment shown, the second threshold in this application is used to represent 20, the third threshold is 15, and the fourth threshold is 10. Table 1 shows that the minimum second difference for refrigerated silicone is 10; therefore, if the second difference is greater than or equal to the fourth threshold, it is determined to be in a refrigerated state. Similarly, for refrigerated plastic baby bottles, the minimum second difference is 15, meaning the second difference is greater than or equal to the third threshold, determining the liquid state to be refrigerated. For refrigerated glass baby bottles, the minimum second difference is 20, meaning the second difference is greater than or equal to the second threshold, determining the liquid state to be refrigerated. Table 2 shows that the maximum second difference for room temperature silicone baby bottles is 9, conforming to the above judgment rule. The maximum second difference for room temperature plastic is 14, conforming to the above judgment rule. The maximum second difference for room temperature glass baby bottles is 19, also conforming to the above judgment rule. It is understood that the specific values ​​of the above thresholds are exemplary examples, and those skilled in the art can set specific threshold values ​​according to actual scenarios; this application does not impose specific limitations.

[0092] Optionally, in one embodiment of the present invention, determining the heating temperature and countdown timer based on the liquid state, the bottle material, and the bottle capacity using a temperature adjustment strategy includes:

[0093] If the bottle is made of glass, has a first capacity, and the liquid is in a refrigerated state, the pouring temperature is determined to be the first pouring temperature, and the countdown timer is determined to be the first time; or, if the bottle is made of plastic, has a first capacity, and the liquid is in a refrigerated state, the pouring temperature is determined to be the second temperature, and the countdown timer is determined to be the second time; or, if the bottle is made of silicone, has a first capacity, and the liquid is in a refrigerated state, the pouring temperature is determined to be the third temperature, and the countdown timer is determined to be the third time; the second temperature is greater than or equal to the first pouring temperature, and the third temperature is greater than or equal to the second temperature; the second time is longer than the first time, and the third time is longer than the second time;

[0094] or,

[0095] If the bottle is made of glass, the bottle capacity is the second capacity, and the liquid is in a refrigerated state, the heating temperature is determined to be the fourth temperature, and the countdown time is determined to be the fourth time; or, if the bottle is made of glass, the bottle capacity is the second capacity, and the liquid is in a room temperature state, the heating temperature is determined to be the fourth temperature, and the countdown time is determined to be the fifth time; the fourth time is longer than the fifth time.

[0096] In some possible implementations, the temperature adjustment strategy in this application can be in tabular form, using a table to look up the pouring temperature and countdown timer for the current liquid state, current bottle material, and current bottle capacity. The temperature adjustment strategy can also be in curve form, using a curve to look up the pouring temperature and countdown timer for the current liquid state, current bottle material, and current bottle capacity. Of course, the temperature adjustment strategy can also be in formula form, using a formula to calculate the pouring temperature and countdown timer for the current liquid state, current bottle material, and current bottle capacity. This application does not limit the specific form of the temperature adjustment strategy.

[0097] For example, referring to the temperature adjustment strategies given in Tables 4 and 5, the brewing temperature and countdown timer are found under the current liquid state, current bottle material, and current bottle capacity. Table 4 shows the correspondence between bottle material, bottle capacity, brewing temperature, and countdown timer under refrigerated conditions; Table 5 shows the correspondence between bottle material, bottle capacity, brewing temperature, and countdown timer under room temperature conditions. In this embodiment, the countdown timer represents the time required to shake the milk and wait for it to warm, given a fixed bottle material, bottle capacity, and liquid state. It should be noted that in the embodiments shown in Tables 4 and 5, the bottle capacity is measured in ounces (OZ). It is understood that other units of measurement can also be used. This embodiment does not limit the specific unit of bottle capacity. Similarly, the measurement of temperature and time can be set as needed. The bottle material and bottle capacity in Tables 4 and 5 provide some common settings; of course, the bottle material and bottle capacity in Tables 4 and 5 can be adjusted according to different usage habits in different regions. The set temperature in the table is determined by considering the time required to heat to a suitable temperature and the time required to exceed 42°C, taking into account regional climate and air pressure characteristics. The maximum temperature is the highest temperature the tank can reach after heating stops; the maximum value does not exceed the set temperature by 3°C. Based on user habits, the suitable drinking temperature for room temperature brewing in this embodiment is 37°C; the suitable drinking temperature for heated frozen breast milk is 31°C. Similarly, dairy products are prone to losing their original nutrients when heated above 42°C; therefore, the maximum value is set to 42°C. 37°C / min:s in the table represents the time required for the milk temperature to reach 31 / 37°C; the heating time is the normal level in the market, i.e., the countdown time in this embodiment. 42°C / min:s in the table represents the time required for the milk temperature to reach 42°C, based on the product's usage setting: "Regardless of the material or initial breast milk state, once the milk temperature reaches the suitable drinking temperature, even if heating continues, it will not reach above 42°C within 3 minutes." As can be seen from the data in the table, the heating is turned off after the water temperature in the tank reaches the set reheat temperature using the control method of this application, and the maximum temperature will not be too high. Therefore, the temperature of the liquid in the bottle will not be too high either.

[0102] Optionally, in one embodiment of the present invention, receiving the milk warming command, starting the milk shaking, and obtaining several first temperatures includes:

[0103] Receive the milk warming instruction, start shaking the milk, and obtain the second accumulated time;

[0104] If the second cumulative duration is less than or equal to the preset duration, obtain several first temperatures;

[0105] Alternatively, if the second cumulative duration exceeds the preset duration, return to the step of performing milk shaking and heating based on the brewing temperature and the countdown duration.

[0106] In some possible implementations, the second cumulative duration in this application embodiment is used to characterize the elapsed time since the milk warming command was received. The preset duration is the time for shaking the milk to determine the liquid state. In some embodiments, the preset duration may be 15 seconds; within 15 seconds, only shaking the milk is performed to determine the liquid state. After 15 seconds, shaking and heating are performed according to the warming temperature and the countdown duration.

[0107] Optionally, in one embodiment of the present invention, performing milk shaking and heating according to the milk temperature and the countdown timer includes:

[0108] Turn on heating, obtain the current temperature of the water bath, and if the current temperature is greater than or equal to the splash temperature, stop heating;

[0109] Start the milk shaking, display the countdown timer, and stop shaking when the countdown ends.

[0110] In some possible implementations, the heating temperature in the embodiments of this application is used to control the heating process, and the countdown time is used to control the shaking of the milk, thereby accelerating the temperature transfer between the water in the tank and the liquid in the bottle by shaking the milk.

[0111] Optionally, in some embodiments, the water temperature in the tank is determined by measuring the temperature of the NTC. When controlling the water tank heating using the NTC temperature, the charging temperature needs to be compensated and adjusted. Specifically, referring to Table 6, the charging temperature is compensated for the capacity and material of each bottle under refrigeration conditions. The compensated NTC trip temperature is used to characterize the preset temperature of the NTC. By measuring the current NTC temperature in real time, the current NTC temperature is compared with the preset NTC temperature to determine whether to turn off the heating. In this embodiment, in addition to the sensor built into the water tank (NTC; located on the surface of the heating plate), an external temperature sensor is installed on the upper part of the water tank; the set charging temperature in the table refers to the temperature of this external temperature sensor, i.e., the charging temperature in this embodiment. It can be understood that since the NTC is located at the bottom of the water tank, heating needs to be stopped at a temperature higher than the set charging temperature in order for the water in the tank to reach the set charging temperature; through experiments, the data in Tables 6 and 7 are obtained by simultaneously observing the NTC temperature and the external temperature sensor.
