The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.
The embodiment of the application provides a control method, which is applied to household appliances, wherein the household appliances can be an electric cooker, an electric hot water bottle, an electric pressure cooker or an electric steamer, and the control method is not limited here. Fig. 1 is a schematic flow chart of an implementation of a control method provided in an embodiment of the present application, and as shown in fig. 1, the method includes:
step S101: and when the self is determined to be in the first working state, acquiring a time change parameter and a temperature change parameter of an object accommodated in the self according to a preset rule.
Here, in this embodiment, the first operating state may be a heating state, and when the household electrical appliance such as an electric rice cooker or an electric hot water bottle is in the heating state, the preset rule may be a preset time length or a preset temperature change value, the time change parameter may be a time change value or a time change rate, and the temperature change parameter may be a temperature change value or a temperature change rate. The method includes the steps of heating food materials or water contained in household appliances such as an electric cooker or an electric hot water bottle and the like so that time variation parameters and temperature variation parameters of the contained food materials or water can be obtained according to preset rules. And, install the temperature sensor in this household electrical appliances, in order to obtain the temperature variation value of the food material or water that this household electrical appliances hold.
Because the thermistor has the characteristics of high sensitivity, good stability, wide working temperature range, small size, convenience in use and the like, in practical implementation, the temperature sensor can be a thermistor. The thermistor can be arranged at the center of the bottom of the inner container of the household appliance, and also can be arranged on the side wall of the inner container corresponding to the preset liquid level parameter of the household appliance, and the position is not limited.
When the thermistor is installed at the center of the bottom of the inner container of the household appliance, the inner container of the household appliance generally has better thermal conductivity, so that the temperature change value of the inner part of the household appliance obtained by the thermistor can be considered as the temperature change value of water or food contained in the inner container of the household appliance, and the current liquid level parameter of the household appliance is accurately calculated according to the temperature change value. When the thermistor is installed on the inner container side wall corresponding to the preset liquid level parameter of the household appliance, whether the object accommodated by the household appliance is insufficient can be determined directly at the moment according to the temperature change parameter or the time change parameter obtained through the thermistor.
Step S102: and determining whether the current liquid level parameter of the accommodated object meets a preset liquid level condition or not according to the temperature change parameter and the time change parameter.
Here, before actual processing, a mapping relation table is preset based on the home appliance device, where the mapping relation table at least represents a mapping relation between a temperature change parameter, a time change parameter, and a liquid level parameter, and the mapping relation table is used to determine a current liquid level parameter corresponding to the temperature change parameter and the time change parameter, where the current liquid level parameter may be a current volume of an object accommodated in the home appliance device, for example, the current liquid level parameter may be 1L or 500ml, and in some embodiments, the liquid level parameter may also be represented by a height.
The preset liquid level condition can be a preset liquid level parameter, and after the current liquid level parameter of the object accommodated in the household appliance is determined, whether the current liquid level parameter of the accommodated object meets the preset liquid level condition is further determined; the determining step may be performed by determining whether a current liquid level parameter of the accommodated object satisfies a preset liquid level condition, and determining whether the current liquid level parameter of the accommodated object in the household appliance is less than or equal to a preset liquid level parameter, where the preset liquid level parameter may be represented by a volume, and may be represented by a height in some embodiments. When the current liquid level parameter of the object contained in the liner of the household appliance is less than or equal to the preset liquid level parameter, indicating that the object contained in the liner of the household appliance is insufficient; for example, when the capacity of the household electrical appliance is 5L, the preset liquid level parameter may be set to 1L or 0.5L.
Step S103: and outputting prompt information when the current liquid level parameter is determined to meet the preset liquid level condition.
Here, the prompt message is used for prompting that the object contained in the prompt message is insufficient.
And determining that the current liquid level parameter meets a preset liquid level condition, wherein the current liquid level parameter of the accommodated object in the household appliance is smaller than or equal to the preset liquid level parameter, and when the current liquid level parameter is smaller than or equal to the preset liquid level parameter, the current internal capacity of the household appliance is insufficient, and at the moment, prompt information capable of representing that the accommodated object is insufficient needs to be output to remind a user.
The insufficient capacity may be nothing in the inner container of the household appliance or a small amount of objects contained in the inner container, and the objects may be porridge, soup, fruit juice or water, which is not limited herein.
The output prompt information can be output in a mode of flashing an object lack indicator lamp on the household appliance, sounding a buzzer and the like, and aims to remind a user that the household appliance is insufficient in the accommodated object or the inner container of the household appliance is empty; in addition, the prompt information is not continuously output but has a time limit, and it may be set that when the home appliance receives a key operation or a terminal establishing internet of things connection with the home appliance receives a key operation within a set time (for example, within 2 hours), it indicates that the prompt information has been successfully forwarded to the user, and the user may select to add water or rice to the home appliance according to the current actual situation of the user, or may directly turn off the power supply without adding anything.
Correspondingly, when the household appliance does not receive any key operation within the set time or the terminal establishing the internet of things connection with the household appliance does not receive the key operation, the prompt information is not successfully transferred to the user, and at the moment, the household appliance stops outputting the prompt information and turns off the power supply.
The control method of the embodiment of the application determines whether the current liquid level parameter of the accommodated object meets the preset liquid level condition or not based on the time variation parameter acquired when the control method is in the first working state and the temperature variation parameter of the accommodated object in the control method, and outputs prompt information for prompting that the accommodated object is insufficient when the current liquid level parameter meets the preset liquid level condition, so that whether the accommodated object is insufficient or not is determined based on the temperature variation parameter and the time variation parameter of the accommodated object in the household appliance such as an electric hot water bottle or an electric rice cooker on the premise of reducing the design cost and the manufacturing cost, and the intelligence and the functional diversity of the household appliance are effectively improved.
In some embodiments, referring to fig. 2A, the step S101 of obtaining the time variation parameter and the temperature variation parameter of the object accommodated in the self-body according to the preset rule may be implemented by performing the following steps:
step S1011 a: and acquiring the temperature change value of the object accommodated by the self-body in a preset time.
Here, the preset time duration may be a time duration between two time instants recorded in the heating process of the object accommodated in the household electrical appliance itself, wherein the former time instant is earlier than the latter time instant.
Accordingly, the temperature change value may be regarded as an absolute value of a temperature difference between a first temperature corresponding to the previous time and a second temperature corresponding to the subsequent time.
Step S1012 a: and determining the preset time length as a time change parameter, and determining the temperature change value as a temperature change parameter.
Here, the time variation parameter may be a time duration between two recorded moments of the object accommodated in the household electrical appliance itself in the heating process, and the temperature variation parameter may be an absolute value of a temperature difference between a first temperature corresponding to the previous moment and a second temperature corresponding to the subsequent moment.
In the embodiment, the time variation parameter and the temperature variation parameter of the object accommodated in the household appliance are determined by the two moments recorded in the heating process of the household appliance and the temperatures corresponding to the two moments, so that the purpose of quickly and accurately acquiring the required time variation parameter and the required temperature variation parameter without additionally adding a peripheral detection circuit is realized, and the design cost and the manufacturing cost of the household appliance are reduced.
In some embodiments, referring to fig. 2B, the step S101 obtains the time variation parameter and the temperature variation parameter of the object accommodated in the self-body according to the preset rule, and may further be implemented by performing the following steps:
step S1011 b: and acquiring the working time corresponding to the preset temperature change value when the temperature change of the object accommodated by the self-body reaches the preset temperature change value.
Here, when the object accommodated in the household electrical appliance records a first current time corresponding to a first current temperature value in a heating process, then records a second current time corresponding to a second current temperature after the accommodated object is heated, and if a difference value between the second current temperature and the first current temperature is equal to a preset temperature change value, a duration between the second current time and the first current time is determined as a working duration corresponding to a preset temperature change value reached by a temperature change of the accommodated object.
Step S1012 b: and determining the preset temperature change value as a temperature change parameter, and determining the working time length as a time change parameter.
Here, the temperature change parameter may be a difference between the second current temperature and the first current temperature, and the time change parameter may be a time period between the second current time and the first current time.
In this embodiment, when the difference between the two temperatures recorded by the household appliance in the heating process is equal to the preset temperature change value, the time change parameter and the temperature change parameter of the object accommodated in the household appliance are determined based on the two temperatures and the moments corresponding to the two temperatures, so that the purpose of quickly and accurately acquiring the required time change parameter and the required temperature change parameter without additionally adding a peripheral detection circuit is achieved, and the design cost and the manufacturing cost of the household appliance are reduced.
In some embodiments, when the temperature sensor is disposed on the sidewall of the liner of the household electrical appliance, the step S102 may be implemented by:
step 1021: and if the temperature change parameter is smaller than a preset temperature change threshold value or the time change parameter is larger than a preset time change threshold value, determining that the current liquid level parameter of the accommodated object meets a preset liquid level condition.
Here, a temperature sensor is installed in a household appliance such as an electric cooker or an electric hot water bottle, and the temperature sensor may be a thermistor, and when the thermistor is installed on a sidewall of an inner container corresponding to a preset liquid level parameter of the household appliance, the temperature sensor may be compared with a time variation parameter or a temperature variation parameter obtained when the inner container of the household appliance is filled with water or food materials; the time variation parameter or the temperature variation parameter obtained when the liner of the household appliance is filled with water or food materials can be regarded as the preset time variation threshold value or the preset temperature variation threshold value.
When the temperature sensor set up in when the domestic electrical equipment predetermine on the inner bag lateral wall that the liquid level parameter corresponds, if the current liquid level parameter of domestic electrical equipment is less than or equal to and predetermines the liquid level parameter, then, the temperature variation of heat sensor sensing will be less than or record the length of time that the temperature variation corresponds will be bigger, promptly the temperature variation parameter is less than predetermined temperature variation threshold value or the time variation parameter is greater than predetermined time variation threshold value, thereby, also can be according to the temperature variation parameter with the time variation parameter directly determines that the current liquid level parameter of present holding object satisfies predetermined liquid level condition.
In this embodiment, through with temperature sensor setting when the inner bag lateral wall that the preset liquid level parameter of tame electric installation corresponds, can directly confirm that tame electric installation self contained object is not enough based on the temperature variation parameter and the time variation parameter that determine, effectively improved whether not enough rapidity and the ease of operation nature of the home electric installation self contained object of confirmation.
In some embodiments, when the mapping relationship further represents a mapping relationship between a temperature change rate and a liquid level parameter, correspondingly, referring to fig. 3, step S102 determines a current liquid level parameter of the accommodated object according to the temperature change parameter, the time change parameter and a preset mapping relationship table, and may also be implemented by the following steps:
step S1021: determining a current temperature change rate based on the temperature change parameter and the time change parameter.
Here, the current temperature change rate may be regarded as a ratio between the temperature change parameter and the time change parameter.
Step S1022: and determining the liquid level parameter corresponding to the current temperature change rate as the current liquid level parameter of the accommodated object based on the mapping relation table.
Here, the mapping relationship table may represent mapping relationships between a temperature change rate, a temperature change parameter, a time change parameter, and a plurality of different liquid level parameters of the home appliance itself, and therefore, based on the current temperature change rate and the mapping relationship table, a liquid level parameter corresponding to the current temperature change rate may be determined, thereby determining the current liquid level parameter of the object accommodated by the mapping relationship table.
For example, the household electrical appliance is provided with A, B, C, D, E liquid level parameters, and the temperature change parameter P is respectively determined when the liquid level parameter is A through the same heating power conditionATime variation parameter TAAnd rate of change of temperature PA/TATemperature variation parameter P when the liquid level parameter is BBTime variation parameter TBAnd rate of change of temperature PB/TBTemperature variation parameter P when the liquid level parameter is CCTime variation parameter TCAnd rate of change of temperature PC/TCTemperature variation parameter P when the liquid level parameter is DDTime variation parameter TDAnd rate of change of temperature PD/TDTemperature variation parameter P when the liquid level parameter is EETime variation parameter TEAnd rate of change of temperature PE/TE(ii) a Wherein, PA、TARespectively has a plurality of, and each PACorresponds to a TA，PB、TBRespectively have a plurality ofAnd each PBCorresponds to a TB，PC、TCRespectively has a plurality of, and each PCCorresponds to a TC，PD、TDRespectively has a plurality of, and each PDCorresponds to a TD，PE、TERespectively has a plurality of, and each PECorresponds to a TE. Therefore, the rapidity and flexibility of determining the current liquid level parameters corresponding to the acquired temperature change parameters and time change parameters can be effectively improved.
Correspondingly, the mapping relation table can also represent the mapping relation among the time change rate, the time change parameter, the temperature change parameter and a plurality of different liquid level parameters of the household appliance, wherein the time change rate is the ratio of the time change parameter to the temperature change parameter.
The household electrical appliance is also set to have A, B, C, D, E liquid level parameters, and the time variation parameter T when the liquid level parameter is A is respectively determined through the same heating power conditionATemperature variation parameter PAAnd a time rate of change TA/PATime variation parameter T when the liquid level parameter is BBTemperature variation parameter PBAnd a time rate of change TB/PBTime variation parameter T when the liquid level parameter is CCTemperature variation parameter PCAnd a time rate of change TC/PCTime variation parameter T when the liquid level parameter is DDTemperature variation parameter PDAnd a time rate of change TD/PDTime variation parameter T when the liquid level parameter is EETemperature variation parameter PEAnd a time rate of change TE/PE(ii) a Wherein, TA、PARespectively have a plurality of, and each TACorresponds to a PA，TB、PBRespectively have a plurality of, and each TBCorresponds to a PB，TC、PCRespectively have a plurality of, and each TCCorresponds to a PC，TD、PDRespectively have a plurality of, and each TDCorresponds to a PD，TE、PERespectively have a plurality of, and each TECorresponds to a PE. Therefore, the rapidity and flexibility of determining the current liquid level parameters corresponding to the acquired temperature change parameters and time change parameters can be effectively improved.
Therefore, the current time change rate is determined according to the temperature change parameter and the time change parameter, and the liquid level parameter corresponding to the current time change rate can be determined as the current liquid level parameter of the accommodated object.
In the embodiment, the current liquid level parameter of the object contained in the household appliance is determined based on the preset mapping relationship between the temperature change rate, the temperature change parameter, the time change parameter (or the time change rate, the time change parameter, the temperature change parameter) and different liquid level parameters of the household appliance, so that the rapidity and the flexibility of determining the current liquid level parameter corresponding to the obtained temperature change parameter and the obtained time change parameter can be effectively improved, the reliability and the accuracy of determining the current liquid level parameter can be effectively improved, and a basis is provided for subsequently determining whether the object contained in the household appliance is insufficient.
In some embodiments, the control method may further perform the steps of:
step S41: and when determining that the self is in the second working state, receiving a first operation instruction for acquiring the current liquid level parameter of the self contained object.
Here, the power of the second operating state is smaller than the power of the first operating state, for example, the second operating state may be a warm state. When the household appliance determines that the household appliance is currently in a heat preservation state, a first operation instruction for acquiring the current liquid level parameter of an object accommodated by the household appliance can be received, wherein the first operation instruction can be an operation instruction generated by directly triggering the household appliance by a user, or an instruction generated by executing touch operation on a terminal display screen establishing the internet of things with the household appliance by the user, and the instruction is not limited here.
Of course, in some embodiments, the first operation instruction may also be automatically triggered by the processor when a certain time condition is reached. The first operating instruction may be triggered, for example, once an hour to determine the current level parameter.

The second method also presupposes that, through a large number of experimental data, second reference data for Δ T/Δ P are obtained for the same heating capacity at different water levels for a corresponding product configuration (in particular a specific heating capacity).
Determining that the second reference data is similar to the first reference data, and setting a water shortage level line; for example, when the set water shortage level is also 3 centimeters and the capacity of the inner container of the electric hot water bottle is 30 centimeters, the second reference data determined by a large amount of experimental data are Δ T/Δ P under the condition of the same heating power at 1 centimeter under the heating condition, Δ T/Δ P under the condition of the same heating power at 2 centimeters, Δ T/Δ P and … … under the condition of the same heating power at 3 centimeters, and Δ T/Δ P under the condition of the same heating power up to 30 centimeters.
This second method is also to start recording the time T1 at a certain P1 temperature during the boiling of water; then, when the water temperature is detected to rise to the temperature P2, the current temperature T2 is recorded again, so that the time variation quantity delta T (T2-T1) in the temperature delta P (P2-P1) can be calculated, the water level can be judged by directly comparing the delta T with second reference data, or the time required for each temperature variation is calculated, namely delta T/delta P. After the value is obtained, the value can be compared with the second reference data, so that the current water level in the electric hot water bottle can be reversely obtained.
