Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a temperature measurement method for a wall breaking machine. Background Art

[0002] As living standards improve, users have higher and higher requirements for food processing methods and processing effects, and the demand for various household appliances for processing food is also gradually increasing. Among them, wall breakers are very popular because they can make a variety of ingredients. Wall breakers can be used to make hot drinks. Generally, temperature sensors (Negative Temperature Coefficient Sensors) are used to detect liquid temperature and control heating. The temperature sensor controls the slurry temperature and food crushing time to ensure that the nutrients of the food are fully released.

[0003] In the prior art with application number CN202221266737.4, in order to achieve accurate temperature measurement, the food processing device needs to be equipped with two temperature measuring devices, which leads to high hardware cost and complicated installation process. In the prior art with application number CN202222409375.6, in order to improve the temperature measurement effect, the temperature sensor of the food processing machine is arranged on the side wall of the cup body. However, due to the limitations of the cup body structure and installation space, the temperature sensor is preferably arranged at the bottom of the cup body.

[0004] When the temperature sensor of the wall-breaking machine is designed at the bottom of the cup, the temperature measurement method at the bottom will be affected by factors such as the uniformity of the slurry temperature in the cup, the temperature of the bottom heating plate, the adhesion of ingredients, and the response speed of the temperature sensor, resulting in inaccurate temperature measurement. Inaccurate temperature measurement by the temperature sensor not only affects the taste of the ingredients, but also leads to safety risks such as undercooked or overflowing ingredients. Summary of the invention

[0005] The purpose of the embodiment of the present application is to provide a temperature measurement method for a wall breaking machine, which is used to accurately measure the temperature of the material in the cup during the operation of the wall breaking machine, so as to avoid affecting the taste of the food due to inaccurate temperature measurement, and avoid safety risks such as undercooked or overflowing food.

[0006] On the one hand, the present application provides a temperature measurement method for a wall breaking machine, which is applied to the wall breaking machine, wherein the wall breaking machine includes a cup body, a heating device, a stirring component, and a temperature sensor disposed at the bottom of the cup body, including:

[0007] In the preheating stage, the material in the cup is heated by the heating device;

[0008] Determine a temperature measurement cycle of the temperature sensor, measure the temperature of the material in the cup by the temperature sensor in each temperature measurement cycle, obtain multiple temperatures, and use the lowest temperature of the multiple temperatures as the current temperature of the material in the cup;

[0009] Repeat the temperature measurement cycle until the current temperature reaches the target temperature.

[0010] In one embodiment, the method further comprises:

[0011] During the temperature measurement period, the maximum difference between the multiple temperatures obtained does not exceed 3 degrees Celsius.

[0012] In one embodiment, before measuring the temperature of the material in the cup in each temperature measurement cycle, the method further includes:

[0013] The stirring component is controlled to rotate to stir the material in the cup.

[0014] In one embodiment, the duration of the temperature measurement cycle is determined by:

[0015] The temperature measurement period is determined according to the capacity of the material in the cup, the specific heat capacity of water, the first power and the thermal efficiency; wherein the duration S of the temperature measurement period is c =(L*c) / (P1*α), L is capacity, c is specific heat capacity of water, P1 is first power, α is thermal efficiency; wherein, the first power is the power for heating the material in the cup during the temperature measurement period.

[0016] In one embodiment, the method further comprises:

[0017] Determine whether the duration of the temperature measurement cycle is within a preset duration interval. If not, use the boundary value of the duration closest to the temperature measurement cycle within the duration interval as the corrected duration of the temperature measurement cycle; wherein the duration interval is [3 seconds, 15 seconds].

[0018] In one embodiment, the method further comprises:

[0019] If the current temperature corresponding to any temperature measurement period does not reach the target temperature, the material in the cup is heated based on the second power;

[0020] After heating to the specified heating time, enter the next temperature measurement cycle.

[0021] In one embodiment, the specified heating time is determined by:

[0022] Determining a temperature increase difference between the target temperature and the current temperature;

[0023] The target heating time is determined according to the volume of the material in the cup, the specific heat capacity of water, the second power, the thermal efficiency and the temperature rise difference; wherein the target heating time S j=(L*c) / (P2*α)*dT, L is the capacity, c is the specific heat capacity of water, P2 is the second power, α is the thermal efficiency, and dT is the temperature rise difference;

[0024] The target heating time is multiplied by the adjustment coefficient to obtain the designated heating time; wherein the adjustment coefficient has a value range of 80% to 100%.

[0025] In one embodiment, the target temperature is determined based on a function selection instruction, and the function selection instruction indicates that a corresponding target temperature is set in each processing stage.

[0026] In one embodiment, controlling the rotation of the stirring component includes:

[0027] In response to the function selection instruction, determining a target speed and forward and reverse rotation control parameters matching the function selection instruction;

[0028] The stirring component is controlled to rotate according to the target rotation speed and the forward and reverse control parameters until the target stirring time is reached.

[0029] In one embodiment, the target stirring time is determined by:

[0030] The capacity of the material in the cup is determined according to the heating power, heating time, the temperature rise of the material in the cup during the heating time, the specific heat capacity of water and the thermal efficiency; wherein, the capacity L = (P*t*α) / (dT*c), P is the heating power, t is the heating time, α is the thermal efficiency, dT is the temperature rise, and c is the specific heat capacity of water;

[0031] The target stirring time is determined according to the capacity; wherein the target stirring time S m =L / 100, L is the capacity.

[0032] In the present application scheme, after the material in the cup is heated and the temperature is raised, the temperature of the material in the cup is measured multiple times within the temperature measurement period, so as to obtain the temperatures measured at multiple discrete time points, and select the lowest temperature from the multiple temperatures as the current temperature of the material in the cup. This can avoid the problem of inaccurate temperature measurement caused by continuous temperature measurement in the prior art, effectively solve the problem of uneven temperature distribution caused by factors such as food accumulation and slurry temperature difference, and improve the accuracy of temperature measurement by the temperature sensor of the wall breaking machine.

[0033] In the present application, the material in the cup can be stirred before temperature measurement to make the temperature distribution of the material in the cup more uniform. After stirring, the material in the cup will continue to shake due to inertia. Therefore, the temperatures of multiple positions can be measured during the temperature measurement period. The lowest temperature is selected as the current temperature, which can more accurately describe the actual temperature of the material in the cup.

[0034] In the present application, a single temperature sensor can achieve accurate temperature measurement, effectively saving hardware costs and simplifying the installation process. Moreover, a good temperature measurement effect is achieved under the premise that the temperature sensor is arranged at the bottom of the cup body.

[0035] In this application, since the function selection instruction matches the proportion of ingredients in the material in the cup, the material in the cup is stirred with the target speed and forward and reverse control parameters corresponding to the function selection instruction, which can fully stir the material in the cup and ensure uniform temperature distribution of the material in the cup.

[0036] Since the stirring time is automatically adjusted according to the capacity of the material in the cup, the stirring effect of the material in the cup is ensured under different capacities, and the temperature measurement reliability of the temperature sensor is improved.

[0037] Since the temperature sensor is installed on the heating plate at the bottom of the cup body, synchronous heating during the temperature measurement process can prevent the local temperature of the heating plate from being too low, which may cause a large temperature difference with the water temperature in the cup and affect the temperature measurement process of the temperature sensor.

[0038] When the current temperature has not reached the target temperature, the heating time is determined based on the temperature rise difference between the current temperature and the target temperature. This can achieve precise temperature control and avoid slurry overflow due to long heating time, large thermal inertia of the slurry and delayed temperature control action, which effectively improves the safety and user experience of the wall breaking machine.

[0047] The memory 12 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable red-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, disk or optical disk.

[0048] The present application also provides a computer-readable storage medium, which stores a computer program. The computer program can be executed by the processor 11 to complete the temperature measurement method of the wall breaking machine provided in the present application.

[0049] See also Figure 2 , is a flow chart of a temperature measurement method of a wall breaking machine provided in an embodiment of the present application, such as Figure 2 As shown, the method may include the following steps 210 to 230.

[0050] Step 210: preheating stage, heating the material in the cup by a heating device.

[0051] The solution is applied to a wall-breaking machine, which includes a cup body, a heating device, a stirring component, and a temperature sensor arranged at the bottom of the cup body. The heating device may be a heating tube. The stirring component may include a brushless motor and a crushing knife for stirring the material in the cup.

[0052] In the preheating stage, the material in the cup can be heated by the heating device so that the material in the cup can continue to heat up. Here, the heating mode (such as heating power and heating time) in the preheating stage can be determined according to the function selection instruction responded by the wall breaking machine, where the function selection instruction is used to indicate the function currently selected by the wall breaking machine for processing the material in the cup.

[0053] Step 220: Determine the temperature measurement cycle of the temperature sensor, measure the temperature of the material in the cup by the temperature sensor in each temperature measurement cycle, obtain multiple temperatures, and use the lowest temperature among the multiple temperatures as the current temperature of the material in the cup.

[0054] Step 230: Repeat the temperature measurement cycle until the current temperature reaches the target temperature.

[0055] Here, the temperature measurement period is the time period during which the temperature of the material in the cup needs to be measured. The duration of the temperature measurement period can be configured as needed. Exemplarily, the duration of the temperature measurement period can range from 3 seconds to 15 seconds.

[0056] In one embodiment, the multiple temperature measurement cycles may be continuous in time, in which case the next temperature measurement cycle will be entered after one temperature measurement cycle ends. In another embodiment, the multiple temperature measurement cycles may not be continuous in time, in which case there may be a time interval between two adjacent temperature measurement cycles.

[0057] According to the temperature measurement needs, the time point when the current temperature measurement cycle starts and the duration of the temperature measurement cycle can be determined, and then the temperature of the material in the cup is measured multiple times by the temperature sensor during the temperature measurement cycle, so as to obtain the temperature measured at multiple discrete time points. After obtaining multiple temperatures, the lowest temperature can be selected as the current temperature of the material in the cup.

[0058] After obtaining the current temperature, it can be determined whether the current temperature reaches the target temperature. Here, the target temperature is the temperature to which the wall breaker needs to heat the material in the cup. The target temperature can be determined based on the function selection instruction to which the wall breaker responds, where the function selection instruction is used to indicate the function currently selected by the wall breaker to process the material in the cup. In one embodiment, the function selection instruction indicates that corresponding target temperatures are set in each processing stage. The target temperature can be adaptively acquired according to the processing stage of the material in the cup by the current wall breaker. Exemplarily, the target temperature of 0°C to 60°C in the processing stage is 60°C; the target temperature of 61°C to 80°C in the processing stage is 80°C; the target temperature of 81°C to boiling point in the processing stage is the boiling point.

[0059] In one case, if the current temperature reaches the target temperature, the temperature measurement process of this processing stage is completed. In another case, if the current temperature does not reach the target temperature, the temperature of the material in the cup can be continuously measured in the next temperature measurement cycle. After several temperature measurement cycles, when the material in the cup is heated and the current temperature of one temperature measurement cycle reaches the target temperature, the temperature measurement process is completed.

[0060] Through the above measures, after the material in the cup is heated, the temperature of the material in the cup is measured multiple times within the temperature measurement period, so as to obtain the temperatures measured at multiple discrete time points, and select the lowest temperature from the multiple temperatures as the current temperature of the material in the cup. This can avoid the problem of inaccurate temperature measurement caused by continuous temperature measurement in the prior art, effectively solve the problem of uneven temperature distribution caused by factors such as food accumulation and slurry temperature difference, and improve the accuracy of temperature measurement by the temperature sensor of the wall breaking machine.

[0061] In one embodiment, in order to keep the temperature of the material in the cup constant during the temperature measurement period, the material in the cup may be heated during the temperature measurement period. By limiting the duration of the temperature measurement period and the heating power during the temperature measurement period, the maximum difference between the multiple temperatures obtained during the temperature measurement period may be controlled to be no more than 3 degrees Celsius.

[0062] Through this measure, the temperature of the material in the cup can be ensured to be relatively stable, ensuring accurate measurement of the temperature of the material in the cup.

[0063] In one embodiment, before measuring the temperature of the material in the cup in each temperature measurement cycle, the stirring component can be controlled to rotate to stir the material in the cup.

[0064] After the material in the cup is stirred, the temperature of the material in the cup is relatively uniform. At this time, the temperature of the material at the bottom of the cup can be measured by the temperature sensor. The temperature is continuously measured during the temperature measurement cycle, so that multiple temperatures can be measured.

[0065] After the material in the cup is stirred, the temperature is relatively uniform, but the material at different positions may still have temperature differences. After stirring, the material in the cup will continue to shake due to inertia. Therefore, the temperature of multiple positions can be measured during the temperature measurement cycle. Selecting the lowest temperature as the current temperature can more accurately describe the actual temperature of the material in the cup.

[0066] Through the above measures, after the material in the cup is stirred, the temperature is measured from the material in the cup with relatively uniform temperature distribution to achieve the temperature measurement cycle, so that the lowest temperature is selected from the temperatures measured at multiple discrete time points as the current temperature of the material in the cup. This can effectively solve the problem of uneven temperature distribution caused by factors such as food accumulation and slurry temperature difference, and improve the accuracy of temperature measurement by the temperature sensor of the wall breaking machine.

[0067] In one embodiment, when step 220 is executed to measure the temperature of the material in the cup, the material in the cup may be heated based on the first power. The first power needs to meet the following conditions: during the temperature measurement period, the temperature of the material in the cup is not increased by more than 3 degrees Celsius during the heating process of the material in the cup by the first power. Preferably, during the temperature measurement period, the temperature of the material in the cup is not increased by more than 1 degree Celsius during the heating process of the material in the cup by the first power.

[0068] Through the above measures, it can be ensured that during the temperature measurement process, the temperature of the material in the cup can remain stable, and will not drop rapidly due to stopping heating, resulting in the temperature measured during the temperature measurement period not being able to accurately represent the actual temperature of the material in the cup at the beginning of the temperature measurement. In addition, the first power restriction condition also ensures that during the temperature measurement process, the material in the cup will not be heated too quickly, resulting in the temperature measured during the temperature measurement period not being able to accurately represent the actual temperature of the material in the cup at the beginning of the temperature measurement. Since the temperature sensor is installed on the heating plate at the bottom of the cup body, synchronous heating during the temperature measurement process can prevent the local temperature of the heating plate from being too low, which is too different from the water temperature in the cup and affects the temperature measurement process of the temperature sensor.

[0069] In one embodiment, before heating the material in the cup with the first power, the first power can be determined. In the previous use of the wall-breaking machine, the boiling point in the use environment of the wall-breaking machine has been obtained and stored in the memory of the controller, which can make the function of the wall-breaking machine adaptive to the use environment at different altitudes.

[0070] The current boiling point in the memory is read, and the target difference between the target temperature and the current boiling point can be determined. Here, the target temperature is the temperature to which the wall breaking machine needs to heat the material in the cup.

[0071] After determining the target difference, the first power can be converted by the target difference. Here, the conversion method can be configured as needed, and the conversion method can characterize that the first power is positively correlated with the target difference. In other words, the larger the target difference, the larger the first power, and the smaller the target difference, the smaller the first power. The value range of the first power is between 30% and 100% of the rated power of the heating device of the wall breaking machine.

[0072] Through this measure, the material in the cup can be heated with different first powers during the temperature measurement period at different processing stages, and the closer the current processing stage is to the current boiling point, the smaller the corresponding first power is, thereby preventing the material in the cup from overflowing due to thermal inertia after reaching the boiling point.

[0073] In one embodiment, before heating the material in the cup with the first power, the duration of the temperature measurement cycle can be determined. The duration of the temperature measurement cycle can be determined according to the capacity of the material in the cup, the specific heat capacity of water, the first power and the thermal efficiency of the heating device of the wall breaking machine. Here, the capacity of the material in the cup can be determined in the preheating stage, as described below. The specific heat capacity and thermal efficiency of water are known quantities. The first power is determined in the above manner.

[0074] Exemplarily, the duration of the temperature measurement cycle can be expressed by the following formula (1):

[0075] S C =(L*c) / (P1*α) (1)

[0076] Among them, S c is the duration of the temperature measurement cycle; L is the capacity of the material in the cup; c is the specific heat capacity of water, which can be 4.2J / (g*℃); P1 is the first power; α is the thermal efficiency.

[0077] In this case, during the temperature measurement period when the material in the cup is heated at the first power, the temperature of the material in the cup will not rise by more than 1 degree Celsius, thereby ensuring that the temperature of the material in the cup remains stable during the temperature measurement process.

[0078] In one embodiment, after calculating the duration of the temperature measurement cycle in the manner of the aforementioned formula (1), it can be determined whether the duration of the temperature measurement cycle is within a preset duration interval. Here, the duration interval can be configured as needed to ensure that the duration of the temperature measurement cycle is not too short to accurately measure the current temperature, nor too long to affect the normal operation of the wall breaking machine. Exemplarily, the duration interval can be [3 seconds, 15 seconds].

[0079] On the one hand, if the duration of the temperature measurement cycle is within the duration interval, the temperature measurement cycle can be directly applied. On the other hand, if the duration of the temperature measurement cycle is not within the duration interval, the boundary value of the duration closest to the temperature measurement cycle within the duration interval can be used as the corrected duration of the temperature measurement cycle, and the corrected duration is applied for temperature measurement. Exemplarily, if the duration of the temperature measurement cycle is 2.5 seconds, the corrected duration is 3 seconds. Alternatively, if the duration of the temperature measurement cycle is 17 seconds, the corrected duration is 15 seconds.

[0080] Through this measure, the calculated duration of the temperature measurement cycle can be corrected based on the time interval to obtain a reasonable duration of the temperature measurement cycle, ensuring that the temperature of the material in the cup remains stable during the temperature measurement cycle while avoiding the temperature measurement cycle being too short or too long.

[0081] In one embodiment, after executing step 220 and obtaining the current temperature of the material in the cup, on the one hand, if the current temperature reaches the target temperature, the next processing stage can be entered, or if the current temperature reaches the target temperature of the last processing stage, the processing flow of the wall breaking machine is terminated. On the other hand, if the current temperature does not reach the target temperature, the material in the cup can be heated based on the second power. Here, the second power can be configured as needed, and preferably, the second power can be the same as the first power.

[0082] The material in the cup is heated at the second power, and after being heated to a specified heating time, the next temperature measurement cycle can be entered, and the temperature of the material in the cup is measured again in the next temperature measurement cycle.

[0083] Through the above measures, during the processing of the wall breaking machine, the material in the cup can continue to be heated when the current temperature of the material in the cup does not reach the target temperature. In addition, heating at the second power and the specified heating time can achieve accurate control of the temperature of the material in the cup.

[0084] In one embodiment, before heating the material in the cup at the second power, a specified heating time may be determined first.

[0085] First, the temperature difference between the target temperature and the current temperature can be determined, and the temperature difference can be obtained by subtracting the current temperature from the target temperature. In one embodiment, the function selection instruction indicates that the corresponding target temperature is set in each processing stage. Therefore, the target temperature of the current processing stage can be selected, and the temperature difference can be obtained by subtracting the current temperature from the target temperature.

[0086] Furthermore, the target heating time can be determined based on the capacity of the material in the cup, the specific heat capacity of water, the second power, the thermal efficiency of the heating device of the wall breaking machine and the temperature rise difference.

[0087] For example, the target heating time can be calculated by the following formula (2):

[0088]

[0089] Among them, S j is the target heating time; L is the capacity of the material in the cup; c is the specific heat capacity of water, which can be 4.2J / (g*℃); P2 is the second power; α is the thermal efficiency; dT is the temperature rise difference.

[0090] Ideally, after heating the material in the cup with the second power for the target heating time, the material in the cup can be heated to the target temperature. However, during the heating process, there may be fluctuations in the processing power. In order to avoid the problem that the temperature of the material in the cup exceeds the target temperature after heating due to fluctuations in the heating power, the target heating time can be multiplied by the adjustment coefficient to obtain the specified heating time. The adjustment coefficient ranges from 80% to 100%.

[0091] Through this measure, the specified heating time for heating at the second power to heat the material in the cup to a temperature close to the target temperature can be calculated, and the problem of the temperature of the material in the cup exceeding the target temperature after heating is avoided, thereby ensuring accurate control of the temperature of the material in the cup.

[0092] In one embodiment, when controlling the rotation of the stirring component, a target rotation speed and forward and reverse rotation control parameters matching the function selection instruction may be determined in response to the function selection instruction.

[0093] Among them, the function selection instruction is used to indicate the function selected by the wall breaking machine to process the material in the cup. For different functions, the target speed and forward and reverse control parameters corresponding to different functions are pre-stored in the memory of the controller of the wall breaking machine. Here, the target speed indicates the speed at which the stirring component rotates. Exemplarily, the target speed ranges from 500RPM (Revolutions Per Minute) to 3000RPM. For example: the target speed is 1000RPM. The forward and reverse control parameters indicate whether the stirring component needs to be forward and reversed, as well as the forward and reverse mode (for example: forward for 30 seconds, reverse for 30 seconds, alternating).

[0094] After the target rotation speed and the forward and reverse control parameters are obtained, the stirring component can be controlled to rotate according to the target rotation speed and the forward and reverse control parameters until the target stirring time is reached.

[0095] Through the above measures, since the function selection instruction matches the proportion of ingredients in the material in the cup, the material in the cup is stirred based on the target speed and forward and reverse control parameters determined by the function selection instruction, so that the material in the cup can be fully stirred. While completing the processing of the ingredients, the temperature of the material in the cup can be evenly distributed, thereby avoiding the problem of inaccurate temperature measurement by the temperature sensor due to factors such as food accumulation and slurry temperature difference.

[0096] In one embodiment, before controlling the rotation of the stirring component with the target rotation speed and the forward and reverse rotation control parameters, the target stirring time may be determined first.

[0097] Before the wall-breaking machine starts measuring temperature, in the preheating stage, the material in the cup has been heated for a period of time in response to the function selection instruction. Therefore, the capacity of the material in the cup can be determined based on the heating power, heating time, temperature rise of the material in the cup during the heating time, specific heat capacity of water and thermal efficiency of the heating device.

[0098] Here, the heating time before the temperature measurement starts, the heating power during this heating time, and the temperature rise value during this heating time can be captured to determine the capacity of the material in the cup.

[0099] Exemplarily, the capacity of the material in the cup can be calculated by the following formula (3):

[0100] L=(P*t*α) / (dT*c) (3)

[0101] Among them, L is capacity; P is heating power; t is heating time; α is thermal efficiency; dT is temperature rise value; c is specific heat capacity of water, which can be 4.2 J / (g*℃).

[0102] After determining the volume of the material in the cup, the target stirring time can be determined according to the volume. For example, the target stirring time can be calculated by the following formula (4):

[0103] S m =L / 100 (4)

[0104] Among them, S m is the target stirring time, ranging from 5 seconds to 15 seconds; L is the capacity, ranging from 500 ml to 1500 ml.

[0105] Through the above measures, the capacity of the material in the cup can be determined based on the heating speed, and then the target stirring time of the material in the cup during temperature measurement can be determined according to the capacity.

[0106] See also Figure 3 , is a schematic diagram of a temperature measurement process of a temperature measurement method for a wall breaking machine provided in an embodiment of the present application, such as Figure 3As shown, after the function is started, when temperature measurement is required, the stirring component can be controlled to stir the material in the cup with the target speed and forward and reverse control parameters indicated by the function selection instruction, and the stirring continues until the target stirring time is reached, which can make the temperature distribution of the material in the cup more uniform. After stirring, the temperature of the material in the cup can be measured, and multiple temperatures can be obtained during the temperature measurement cycle, and the lowest temperature is used as the current temperature. During the temperature measurement cycle, the material in the cup can be heated by the first power, so that the temperature of the material in the position cup is stable. After obtaining the current temperature, it can be determined whether the current temperature reaches the target temperature of the current processing stage. On the one hand, if it is reached, the temperature measurement process of the current processing stage ends. On the other hand, if it is not reached, the material in the cup can be heated at the second power, and the heating reaches the specified heating time. Further, the step of stirring the material in the cup can be returned. This process can be repeated many times until the current temperature reaches the target temperature.

[0110] The second temperature measurement module 430 is used to repeat the temperature measurement cycle until the current temperature reaches the target temperature.
