In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is to be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with one another without conflict.
In the following description, the terms "first", "second", "third" and the like are merely used to distinguish similar objects and do not represent a specific ordering of the objects, it being understood that the "first", "second", "third" may be interchanged with a specific order or sequence, as permitted, to enable embodiments of the application described herein to be practiced otherwise than as illustrated or described herein.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the 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 electric rice cookers, electric water bottles, electric pressure cookers or electric steamer, and are not limited herein. Fig. 1 is a schematic flow chart of an implementation of a control method according to an embodiment of the present application, as shown in fig. 1, where the method includes:
Step S101: when the temperature of the temperature sensor is determined to be in the first working state, the current temperature of the temperature sensor is obtained.
Here, in this embodiment, the first working state may be a heat-preserving state, and when the home appliance is in the heat-preserving state, the output power of the home appliance is relatively low, so that the boiled water or the cooked food material is preserved, so that the temperature of the water or the food material may be maintained within a certain heat-preserving temperature range. And, a temperature sensor is installed in the home appliance to obtain the temperature inside the home appliance itself.
The thermistor sensor has the characteristics of higher sensitivity, good stability, wide working temperature range, smaller body, convenient use and the like, and can be practically implemented. The thermistor sensor may be mounted on the outer surface of the bottom of the inner container of the home appliance, or may be mounted on the inner surface of the upper cover of the home appliance, which is not limited herein.
When the thermistor sensor is mounted on the outer surface of the bottom of the household electrical appliance, the inner container of the household electrical appliance generally has good heat conductivity, so that the current temperature of the inside of the household electrical appliance obtained through the thermistor sensor can be considered as the current temperature of water or food materials contained in the inner container of the household electrical appliance. When the thermistor sensor is mounted on the inner surface of the upper cover of the household electrical appliance, the temperature obtained by the thermistor sensor at the moment can be the temperature of air in the inner container of the household electrical appliance, and the temperature of the air can be considered as the current temperature of water or food materials contained in the inner container because the upper cover is buckled.
Step S102: and when the current temperature is determined to be lower than the first temperature threshold value, controlling the current temperature to be switched to the second working state.
Here, the first power corresponding to the first working state is smaller than the second power corresponding to the second working state. For example, the second operating state may be a heating state. When the household electrical appliance determines that the current temperature inside the household electrical appliance is smaller than the first temperature threshold, the internal temperature of the household electrical appliance is lower, so that the household electrical appliance needs to be controlled to switch the working state, namely from the heat preservation state to the heating state, so that the household electrical appliance heats, and the internal temperature of the household electrical appliance is ensured to be within a preset heat preservation temperature range.
When the household electrical appliance starts a heat preservation function, a target temperature corresponding to the heat preservation function, a first temperature threshold value, a second temperature threshold value and a heating duration threshold value corresponding to the target temperature are obtained, and the heating duration threshold value is the timing duration of a timer of the household electrical appliance when the household electrical appliance is empty and is heated from the first temperature threshold value to the second temperature threshold value; the first temperature threshold and the second temperature threshold are an upper limit control temperature and a lower limit control temperature of the target temperature, and can be recorded as a heat preservation temperature range of an object inside the household appliance. Therefore, when the home appliance is in a heat preservation state, the current temperature inside the home appliance is between the first temperature threshold value and the second temperature threshold value.
Step S103: and determining a first time period corresponding to the time when the temperature in the self-body reaches the second temperature threshold value.
Here, the first duration may be a duration of time of starting a timer to start counting when the home appliance is heated from the current temperature to the first temperature threshold until the timer is heated to the second threshold; the first time period may be a time period between a first time period when the home appliance is heated from the current temperature to the first temperature threshold value and a second time period when the home appliance is heated to the second temperature threshold value, and is not limited herein.
Step S104: and outputting prompt information when the first time length is determined to meet the preset time length condition.
Here, the prompt information is used to prompt that the capacity of the internal object is insufficient.
The preset time length condition may be a set size relationship between the first time length and the heating time length threshold, where the heating time length threshold is a threshold calculated by a manufacturer from a first temperature threshold to a second temperature threshold when the capacity of an object in each of a plurality of home appliances of the same type as the home appliances is insufficient, and if it is determined that the first time length meets the preset time length condition, the insufficient internal capacity of the home appliances is indicated, and prompt information is output to remind a user.
The insufficient capacity may be that no container is contained in the inner container of the home appliance or that a small amount of objects are contained in the inner container, and the objects may be meal or water, which is not limited herein.
The output prompt information can be output in a mode of flashing of an indication lamp of lack of an object on the household appliance, a buzzer, and the like, so as to remind a user that the object in the household appliance is insufficient or empty; in addition, the prompt information is not continuously and continuously output, but has time limitation, and can be set in a set time (for example, within 24 hours) when the household electrical appliance receives the key operation, so that the prompt information is successfully transferred to the user, and the user can select to add water or meal into the household electrical appliance according to the current actual situation of the user, or can directly turn off the power supply without adding any water or meal.
Correspondingly, when the household electrical appliance does not receive any key operation within the set time, the prompt information is not successfully transferred to the user, and the household electrical appliance stops outputting the prompt information and turns off the power supply.
The control method of the embodiment of the application determines the first time based on the relationship between the current temperature in the household appliance and the two temperature thresholds, which is acquired when the household appliance is in the first working state, and outputs the prompt information for prompting the insufficient capacity when the first time meets the preset time condition, thereby realizing the prompt information prompt user when the internal space of the household appliance is determined to be empty or the built-in object is insufficient based on the temperature in the household appliance such as the electric hot water bottle or the electric rice cooker, and further determining the internal space of the household appliance or the built-in object is insufficient without depending on people and a water gauge, and effectively improving the intelligence of the household appliance.
In some embodiments, referring to fig. 2, following step S101, the following steps may also be performed:
step S21: when the self-starting heat preservation function is determined, the target temperature corresponding to the heat preservation function is obtained.
Here, the user sets a target temperature in advance in a home appliance such as a thermos bottle or an electric rice cooker, and the target temperature is a basis for ensuring that the home appliance is in a heat-insulating state when the heat-insulating function is turned on.
Step S22: and determining a temperature level corresponding to the target temperature.
Here, the temperature level may include three temperature ranges, that is, a low temperature range, a medium temperature range, and a high temperature range, where the low temperature range may be a low temperature threshold, or a low temperature threshold interval, the medium temperature range may be a medium temperature threshold, or a medium temperature threshold interval, and the high temperature threshold may be a high temperature threshold, or a high temperature threshold interval, which is not limited herein.
And matching the value of the target temperature with three temperature gears to determine that the target temperature belongs to a low-temperature gear, a medium-temperature gear and a high-temperature gear, thereby laying a foundation for determining two temperature thresholds and a heating time threshold later.
Step S23: and respectively determining the temperature interval lower limit value, the temperature interval upper limit value and the heating time corresponding to the temperature level as the first temperature threshold value, the second temperature threshold value and the heating time threshold value based on a preset mapping relation table.
Here, when manufacturing household appliances such as an electric thermos bottle or an electric cooker, a manufacturer will set at least one temperature level and a temperature interval corresponding to each temperature level in advance, and perform a large number of experimental tests based on the temperature level and the temperature area, so as to determine a mapping relation table among the temperature level, the temperature interval and the heating time; the temperature interval is an upper limit temperature and a lower limit temperature of a corresponding temperature level, and the heating time is a timing time period when household appliances such as an electric thermos bottle or an electric cooker are heated from the lower limit temperature to the upper limit temperature.
When it is determined that the temperature level includes three temperature ranges of a low temperature range, a medium temperature range, and a high temperature range, the low temperature range may be set to a low temperature threshold range, the medium temperature range may be set to a medium temperature threshold range, and the high temperature range may be set to a high temperature threshold range.
For any low-temperature threshold Q in the low-temperature threshold range, [ Q-Q 1,Q+q2 ] can be set as the lower limit value and the upper limit value of the temperature interval of the low-temperature threshold Q, and the time period for heating the household appliance from Q-Q 1 to Q+q 2 in the heat-preserving state is the heating time of the low-temperature threshold Q; wherein q 1、q2 is a positive integer and may or may not be equal in value. In the specific implementation process, the low temperature threshold range may be [30, 45], the value of Q may be 35, and the values of Q 1、q2 may all be 10.
For any middle temperature threshold C in the middle temperature threshold range, [ C-C 1,C+c2 ] can be set as the lower limit value and the upper limit value of the temperature interval of the middle temperature threshold C, and the time duration for heating the household electrical appliance from C-C 1 to C+c 2 in the heat preservation state is the heating time of the middle temperature threshold C; wherein c 1、c2 is a positive integer and may or may not be equal in value. In the specific implementation process, the medium temperature threshold range may be [50, 70], the value of C may be 50, and the value of C 1、c2 may be 8.
For any one high temperature threshold E in the high temperature threshold range, [ E-E 1,E+e2 ] can be set as a temperature interval lower limit value and a temperature interval upper limit value of the high temperature threshold E, and the time length for heating the household appliance from E-E 1 to E+e 2 in the heat preservation state is the heating time of the high temperature threshold E; wherein e 1、e2 is a positive integer and may or may not be equal in value. In a specific implementation process, the high temperature threshold range may be [75, 90], the value of E may be 75, and the values of E 1、e2 may both be 6.
In this embodiment, the low temperature gear may be set to a low temperature threshold R, the medium temperature gear may be set to a medium temperature threshold H, and the high temperature gear may be set to a high temperature threshold N, and similarly, [ R-R 1,R+r2 ] may be set to a temperature interval lower limit value and a temperature interval upper limit value of the low temperature threshold R, and a time period for heating the home appliance from R-R 1 to r+r 2 in a heat preservation state may be set to a heating time of the low temperature threshold R; wherein r 1、r2 is a positive integer and the values can be equal or unequal; setting [ H-H 1,H+h2 ] as a temperature interval lower limit value and a temperature interval upper limit value of the medium temperature threshold value H, and heating the household electrical appliance from H-H 1 to H+h 2 in a heat preservation state for a heating time of the medium temperature threshold value H; wherein, h 1、h2 is a positive integer and the values can be equal or unequal; setting [ N-N 1,N+n2 ] as a temperature interval lower limit value and a temperature interval upper limit value of the high temperature threshold value N, and heating the household electrical appliance from N-N 1 to N+n 2 in a heat preservation state for a heating time of the high temperature threshold value N; wherein, n 1、n2 is a positive integer and the values may be equal or unequal.
In this embodiment, when it is determined that a home appliance such as an electric cooker or an electric thermos bottle is in a heat preservation state and obtains the current temperature inside the home appliance, a mapping relation table between a temperature level, a temperature interval and a heating time preset in the home appliance such as the electric cooker or the electric thermos bottle by a user is used to determine a target temperature corresponding to a heat preservation function, and a first temperature threshold, a second temperature threshold and a heating time threshold corresponding to the target temperature, so that when the home appliance determines that the home appliance enters the heat preservation state, whether the home appliance needs to be switched to the heating state can be rapidly and accurately determined according to the current temperature inside the home appliance, thereby ensuring that the heat preservation temperature of the built-in object cannot be rapidly reduced.
In some embodiments, the step S103 may be implemented by:
Step S1031: when the temperature inside the device reaches the first temperature threshold value, a timer is started to start timing.
Here, a timer may be installed in the household electrical appliance such as the electric cooker or the electric thermos bottle, and when the household electrical appliance determines that the current temperature in the household electrical appliance is lower than the first temperature threshold, the household electrical appliance switches the current heat preservation state into a heating state and starts heating; and starting the timer to start timing until the temperature in the self-body reaches a first temperature threshold value.
In some embodiments, the time when the temperature inside the device reaches the first temperature threshold may also be determined as the first time.
Step S1032: and when the temperature in the self-body reaches a second temperature threshold value, determining the timing duration of the timer as a first duration.
Here, the first temperature threshold value and the second temperature threshold value are upper limit control temperature and lower limit control temperature of the target temperature, and may be referred to as a holding temperature range within the home appliance itself. Therefore, when the current temperature inside the self-body is between the first temperature threshold value and the second temperature threshold value, the self-body can be ensured to be in a heat-preserving state.
When the temperature of the self-interior reaches a first temperature threshold, comparing the temperature of the self-interior with a second temperature threshold, and continuing to heat until the temperature of the self-interior reaches the second threshold when the temperature is determined to be lower than the second temperature threshold, and determining the timing duration of the timer as a first duration when the heating is stopped.
In some embodiments, the time when the temperature inside the device reaches the second threshold may be recorded as a second time, and the duration between the first time and the second time may be determined as a first duration. And are not limited herein.
In this embodiment, when determining the current temperature lower limit value of the heat preservation temperature of the home appliance such as the electric cooker or the electric thermos bottle, the inside of the home appliance is heated by executing step S1031 and step S1032, and the time period when the heat preservation temperature lower limit value is heated to the heat preservation temperature upper limit value is obtained, so that the temperature inside the home appliance can be ensured to be in a heat preservation state, and the heating time period when the heat preservation temperature lower limit value is heated to the heat preservation temperature upper limit value can be obtained, thereby laying a foundation for quickly determining whether the inside of the home appliance is empty or the built-in object is insufficient.
In some embodiments, referring to fig. 3, the step S104 may be implemented by:
step S1041: and judging whether the first time length is smaller than or equal to the heating time length threshold value.
Here, since the heating duration threshold is a duration threshold obtained when the inner container of the home appliance is empty or the inner container is heated to the second temperature threshold from the first temperature threshold under the condition that few objects are in the inner container, if it is determined that the first duration is less than or equal to the heating duration threshold, it is indicated that no or a small number of objects are in the inner container of the point adding device at this time, and step S1042 is entered; in contrast, if it is determined that the first time period is greater than the heating time period threshold, it is indicated that the objects contained in the inner container of the home appliance are sufficient and do not need to be added, and step S1043 is performed.
Step S1042: and outputting prompt information. The determining of the heating duration threshold is the same as the determining process of the heating duration threshold of step 21 to step 23 in the foregoing embodiment, and will not be described herein again; the first time period is the same as the determination process of the first time period in S1031 and step S1032 in the foregoing embodiment, and will not be described herein.
Here, an indicator light and a buzzer are installed on household electrical appliances such as an electric cooker or an electric thermos bottle, when the household electrical appliances determine that the first time length is less than or equal to the heating time length threshold value, the indicator light starts to flash, and the buzzer starts to sound, so that prompt information is generated to inform a user that the interior of the household electrical appliance is empty or the built-in object is insufficient.
In step S1043, the control unit switches to the first operating state.
When the object contained in the liner of the household electrical appliance is determined to be enough, the household electrical appliance is indicated that the condition that the interior of the household electrical appliance is empty or the built-in object is insufficient does not exist, so that the household electrical appliance can immediately switch the current heating state to the heat preservation state, therefore, the temperature of the object contained in the liner is ensured to be maintained within the heat preservation temperature range, so that the user can eat or drink the object at any time conveniently, and the living experience of the user is effectively improved.
In this embodiment, when it is determined that the interior of a household appliance such as an electric cooker or an electric thermos bottle is empty or the interior of the household appliance is insufficient, a user is reminded to add the interior of the household appliance such as rice or water in time by means of a buzzer and a flashing indicator light installed in the household appliance; meanwhile, when the household electrical appliance determines that the objects in the household electrical appliance are enough, the household electrical appliance can be instantly switched to a heat preservation state, so that the temperature of the objects in the household electrical appliance is ensured to be maintained in a heat preservation temperature range, the household electrical appliance is convenient for a user to eat or drink at any time, and the living experience of the user is effectively improved.
In some embodiments, after the step S104, the following steps may be further performed:
Step S41: judging whether an operation instruction is received within a preset time; the operation instruction may be to open an upper cover of a household appliance such as an electric cooker or an electric thermos bottle, or touch other keys on the household appliance, which is not limited herein.
If no operation instruction is received within the preset time, the process proceeds to step S42; in contrast, if the operation instruction is received within the preset time, the process advances to step S43.
Step S42: stopping outputting the prompt information and turning off the power supply.
Here, the user sets a prompting time (for example, 1 hour) in advance, and when the household electrical appliance such as the electric cooker or the electric thermos bottle determines that the interior of the household electrical appliance is empty or the built-in object is insufficient, the buzzer installed in the household electrical appliance continuously sounds and the indication lamp continuously blinks in the prompting time, so that prompting information is generated; and when the household electrical appliance does not receive the operation instruction in the prompting time, the prompting information is not successfully prompted to the user, at the moment, the buzzer stops ringing, the indicator lamp also stops flashing, and meanwhile, the power supply is turned off.
Step S43: stopping outputting the prompt information and controlling the self-switching to the first working state.
And when the user does not go out for a while, the user can choose to add water or meal into the household electrical equipment, so that the user can eat or drink conveniently later.
In this embodiment, when the household electrical appliance such as the electric cooker or the heating water bottle outputs the prompt information, the step S41 and the step S42 or the step S41 and the step S43 are executed to determine whether the prompt information is successfully prompted to the user, and after the user successfully receives the prompt information, the user can freely select whether to add the built-in object such as water or meal to the household electrical appliance according to the current requirement, so that the user is more flexible and convenient, the practicability is also very strong, and the user experience is also improved.

The technical scheme of the application is further elaborated below by referring to the drawings in the specification and the specific embodiments.
In the embodiment of the application, a control method is further specifically described by taking household appliances as electric water bottles as an example; because the water level of the electric hot water bottle is observed through an external water gauge, the water level is inconvenient to observe due to the fact that the water level is displayed through the structure of the existing water gauge, water in the electric hot water bottle is often not available, but users do not find the electric hot water bottle, and the use of the electric hot water bottle is affected; and, do not effectively remind the user when the electric hot water bottle is in the lack of water state, the user hardly discovers that the electric hot water bottle does not have water yet, influences user's use. According to the embodiment of the application, the purpose of judging whether the electric water bottle has water or not is realized through the electric control program and the thermistor sensor, and the electric control program is fast in detection, so that a user can be reminded in an acousto-optic and electric mode, misjudgment of the water in the electric water bottle by the user is reduced, and the pain point of drinking water by the user is solved.
Referring to fig. 4, a graph of temperature-time change when the capacity of the electric thermos bottle is sufficient and insufficient in the insulation state is shown in the embodiment of the present application. As shown in fig. 4, when the electric hot water bottle sets the target insulation temperature to a, the electric hot water bottle enters an insulation state. The thermistor sensor in the electric thermos detects the current water temperature, and when the current water temperature is lower than A1, the electric thermos starts heating. And detecting the temperature of the electric thermos bottle, and continuously heating when the temperature is lower than the A2 temperature until the temperature reaches the A2 temperature at the moment T3, wherein the electric thermos bottle stops heating. Detecting whether the temperature of the electric thermos bottle is lower than the temperature A1 again, and circulating in such a way to ensure that the electric thermos bottle is between the upper limit A2 temperature and the lower limit A1 temperature of the heat preservation target temperature A; wherein the upper limit A2 temperature corresponds to the upper limit control temperature in the foregoing embodiment, the lower limit A1 temperature corresponds to the lower limit control temperature in the foregoing embodiment, and the insulation target temperature a corresponds to the target temperature in the foregoing embodiment.

The heating time T1 must be less than the heating time T3 due to a lack of water and/or a small amount of water in the electric hot water bottle (i.e., the amount of water is less than a set value, e.g., the amount of water in a 5L capacity electric hot water bottle is less than 0.5L). Therefore, the T1 time is set as the critical time for judging the no water or less water of the electric thermos bottle. Through a large number of experimental tests, the water shortage or less water heating time of the electric hot water bottle in different temperature heat preservation states can be confirmed, so that the electric hot water bottle is judged to be free of water or lack of water through the precaution.
