Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a method for controlling the temperature of a beverage according to the present application, which is used in a refrigerator, freezer or other refrigeration equipment, and for convenience of description, the method for controlling the temperature of a beverage according to the present application is used in a refrigerator.
The temperature control method comprises the following steps:
s110: the surface temperature of the target beverage is monitored as well as the ambient temperature in which the target beverage is located.
A beverage generally comprises a liquid and a package for storing the liquid, the surface temperature of the target beverage being the surface temperature of its package, and the ambient temperature of the target beverage being the ambient temperature around it, in particular the ambient temperature in the compartment in which the target beverage is located.
After receiving the temperature monitoring instruction, the refrigerator starts to monitor the surface temperature of the target beverage and the ambient temperature. For example, in one application scenario, when it is monitored that the user closes the door of the compartment where the target beverage is located, a temperature monitoring instruction is received, in another application scenario, a touch screen or an input key is arranged on the refrigerator, after the user puts the target beverage into the refrigerator, the user inputs an instruction conforming to a preset instruction on the touch screen or inputs a correct instruction by using the input key, the temperature monitoring instruction is received, and in yet another application scenario, when the user puts the target beverage into the refrigerator, the temperature monitoring instruction is received.
After the surface temperature of the target beverage and the ambient temperature of the target beverage are monitored, the monitoring may be performed in real time, or may be performed at preset time intervals, for example, 5 seconds, 30 seconds, and the like.
In this case, the target beverage is a specific beverage in the refrigerator, and for example, in an application scenario, after receiving an instruction to monitor the temperature, a beverage newly placed in the refrigerator before or after receiving the instruction is set as the target beverage. In one application scenario, the refrigerator is provided with a compartment for storing beverages, and when food is detected to be placed in the compartment, the food placed in the compartment is determined to be the beverage. In other application scenarios, the user inputs an instruction to inform the refrigerator that the put-in food is a beverage, and then the subsequent refrigerator sets the put-in beverage as a target beverage.
In an application scenario, a plurality of infrared sensors located in a compartment where a target beverage is located are used for monitoring the temperature in the compartment, and the surface temperature of the target beverage and the ambient temperature of the target beverage are obtained according to the temperature in the compartment. Specifically, the infrared sensor is a sensor for sensing infrared rays radiated from a target and measuring the infrared rays by using physical properties of the infrared rays, a plurality of infrared sensors, for example, 5 or 10 infrared sensors, are distributed in the compartment where the target beverage is located, and the plurality of infrared sensors distributed in the compartment can distinguish the target beverage in the compartment and the size of the target beverage according to the radiation condition of the infrared rays in the whole compartment, so as to obtain the surface temperature of the target beverage and the ambient temperature where the target beverage is located.
In other embodiments, other temperature sensors may be used to monitor the surface temperature of the target beverage and the ambient temperature, which is not limited herein.
S130: and obtaining the packaging material of the target beverage.
Beverages typically have several packages: plastic packaging, glass packaging, metal packaging, paper packaging, and the like.
In an application scenario, the packaging material for the target beverage is obtained according to the change rate of the surface temperature of the target beverage. Specifically, the rate of change of the surface temperature of different packaging materials is different, for example, the rate of decrease of the surface temperature of a metal package is greater than the rate of decrease of the surface temperature of a paper package, so that the packaging material of the target beverage can be known from the rate of change of the surface temperature of the target beverage.
In another application scenario, the packaging material of the target beverage may also be obtained according to the selection of the user, that is, the user actively informs the refrigerator of the packaging material of the target beverage, for example, multiple packaging materials are displayed on the refrigerator, the user selects the packaging material corresponding to the target beverage, or the user manually inputs the packaging material of the target beverage on the refrigerator.
S150: the internal temperature of the target beverage is obtained according to the packaging material, the surface temperature and the ambient temperature of the target beverage.
When the surface temperature and the environmental temperature are the same, different packaging materials may affect the measurement result of the sensor due to different emissivity, when the packaging materials and the environmental temperature are the same, different surface emissivity of different surface temperatures may affect the measurement result of the sensor, and when the surface temperature and the packaging materials are the same, different environmental temperatures may also affect the measurement result of the sensor.
Therefore, in the present embodiment, obtaining the internal temperature of the target beverage according to the three parameters of the packaging material, the surface temperature and the ambient temperature can improve the accuracy of calculation of the internal temperature of the target beverage.
Specifically, the big data may be used to analyze the relationship between the packaging material, the surface temperature, the ambient temperature of the beverage and the internal temperature of the beverage in advance, so as to obtain the relationship between the packaging material, the surface temperature, the ambient temperature and the internal temperature, and thus, after the packaging material, the surface temperature and the ambient temperature of the target beverage are obtained, the internal temperature of the target beverage can be obtained according to the relationship analyzed in advance.
S170: maintaining the internal temperature of the target beverage within a preset temperature range when the internal temperature is reduced to a corresponding designated temperature, wherein the difference between the maximum value and the minimum value of the preset temperature range and the designated temperature does not exceed a difference threshold value.
The difference between the maximum value and the minimum value of the preset temperature range and the specified temperature does not exceed the difference threshold value, and the preset temperature range is near the specified temperature.
When the internal temperature of the target beverage is monitored to be reduced to the corresponding specified temperature, the internal temperature of the target beverage is indicated to be reduced to the target temperature, if the internal temperature is reduced again, potential safety hazards may exist or drinking mouthfeel is affected, and the internal temperature of the target beverage is maintained within a preset temperature range so as to prevent the temperature of the target beverage from being continuously reduced.
From the above, according to the method and the device, the internal temperature of the target beverage is obtained according to the surface temperature of the target beverage, the environment temperature and the packaging material, and the influence of the surface temperature, the environment temperature and the packaging material on the temperature sensed by the sensor is fully considered, so that the accuracy of calculating the internal temperature of the target beverage can be improved, the internal temperature is timely maintained within a preset temperature range when the internal temperature of the target beverage is monitored to be reduced to the corresponding specified temperature, and the phenomenon that the drinking taste is influenced or the frost crack phenomenon is caused due to the fact that the internal temperature of the target beverage is too low is avoided.
Optionally, in this embodiment, before step S170, the method further includes: judging whether a first temperature threshold value exists or not; if so, setting the first temperature threshold value as a specified temperature; and if not, setting the second temperature threshold to be a designated temperature, wherein the second temperature threshold is smaller than the first temperature threshold, and the second temperature threshold corresponds to the freezing point of the target beverage.
The first temperature threshold is set by a user, for example, an optimal drinking temperature set for the user, the second temperature threshold corresponds to a freezing point of the target beverage, the first temperature threshold is greater than the second temperature threshold, when the internal temperature of the target beverage is reduced to the first temperature threshold, if the internal temperature of the target beverage is continuously reduced, the internal temperature of the target beverage is lower than a temperature expected by the user, for example, the internal temperature is lower than the optimal drinking temperature set by the user, so that the drinking taste is affected, when the internal temperature of the target beverage is reduced to the second temperature threshold, if the internal temperature of the target beverage is continuously reduced, liquid in the target beverage is frozen, and the volume is expanded due to freezing, so that the risk of frost cracking of the target beverage exists.
If the first temperature threshold exists, the fact that the temperature threshold is set by the user is explained, the temperature threshold set by the user is considered preferentially, the first temperature threshold is set to be the designated temperature, and therefore when the fact that the internal temperature of the target beverage is reduced to the first temperature threshold is monitored, the internal temperature of the target beverage is maintained within the preset temperature range, and the internal temperature of the target beverage is maintained to be close to the first temperature threshold set by the user as far as possible.
If the first temperature threshold value does not exist, the second temperature threshold value is set to be the designated temperature, namely, when the internal temperature of the target beverage is reduced to the second temperature threshold value, the internal temperature of the target beverage is maintained to be close to the second temperature threshold value, and the phenomenon that liquid in the target beverage is frozen is avoided.
Wherein the second temperature threshold may be set by system default. In particular, there may be differences in freezing points of different beverages, but the differences are small, overall, the freezing points of the beverages are between-2 degrees and-4 degrees, so the system can default to setting the highest freezing point of all beverages to the second temperature threshold, for example, to-2 degrees.
Of course, in other embodiments, the second temperature threshold may also be set by the user, for example, when the user issues an instruction to monitor the temperature, the refrigerator prompts the user to prompt the user to input the corresponding freezing point of the target beverage, so as to store the temperature value input by the user as the second temperature threshold.
Or, in consideration of the difference in probability of occurrence of frost crack in beverages of different packaging materials, the second temperature threshold value corresponds to the packaging material of the target beverage, for example, the toughness of the plastic package is higher than the toughness of the glass package, and therefore the probability of occurrence of frost crack in the target beverage of the plastic package is lower than the probability of occurrence of frost crack in the target beverage of the glass package, and further, the second temperature threshold value corresponding to the target beverage of the plastic package is set to be lower than the second temperature threshold value corresponding to the target beverage of the glass package, and specifically, after the packaging material of the target beverage is obtained, the second temperature threshold value corresponding to the target beverage is determined based on the correspondence relationship between the pre-stored packaging material and the second temperature threshold value.
In an application scenario, the method for controlling the temperature of the beverage further comprises: and receiving a temperature value input by a user, and saving the temperature value as a first temperature threshold value. Specifically, a user may input a temperature value through an input tool such as a key on the refrigerator, and then the refrigerator stores the temperature value as the first temperature threshold.
In another application scenario, in order to avoid that the temperature value input by the user is smaller than the second temperature threshold value, the above steps cannot be performed, and therefore, the method for controlling the temperature of the beverage further comprises: and displaying a plurality of temperature values for selection by a user, and storing the temperature values selected by the user as a first temperature threshold value. Specifically, a plurality of temperature values are displayed on a display screen on the refrigerator and can be selected by a user, and when it is monitored that the user selects a certain temperature value, the temperature value selected by the user is stored as a first temperature threshold value.
Referring to fig. 2, fig. 2 is a schematic flow chart of another embodiment of the method for controlling the temperature of a beverage according to the present application, in which the method for controlling the temperature of a beverage includes:
s210: the surface temperature of the target beverage is monitored as well as the ambient temperature in which the target beverage is located.
The same as step S110 in the above embodiment.
S220: and obtaining the packaging material of the target beverage.
The same as step S130 in the above embodiment.
S230: the internal temperature of the target beverage is obtained according to the packaging material, the surface temperature and the ambient temperature of the target beverage.
The same as step S150 in the above embodiment.
S240: and sending out prompt information when the internal temperature is reduced to the corresponding specified temperature.
The prompt message is sent to remind the user to take out the target beverage from the refrigerator, wherein the prompt message may be an audio alarm prompt, a light alarm prompt or other prompt modes, which is not limited herein.
In different application scenarios, the prompt messages may be different, for example, in one application scenario, when the specified temperature is the first temperature threshold, a prompt message with a prompt intensity of a first level is sent, in another application scenario, when the specified temperature is the second temperature threshold, a prompt message with a prompt intensity of a second level is sent, the first level is smaller than the second level, specifically, when the internal temperature of the target beverage is reduced to the first temperature threshold, there is no potential safety hazard, and when the internal temperature of the target beverage is reduced to the second temperature threshold, there is a risk of frost cracking of the target beverage, so when the specified temperature is the second temperature threshold, the prompt message with a greater intensity is used for prompting.
S250: detecting whether the target beverage is taken away by the user.
Specifically, whether the target beverage is taken away by the user is judged according to whether the temperature difference exists in the chamber where the target beverage is located: when the target beverage is not taken away from the compartment by the user, a temperature difference exists between the position where the target beverage is placed and the surrounding environment, and the temperature difference disappears when the target beverage is taken away from the compartment by the user.
When it is detected that the target beverage is taken away by the user, the step S260 is entered, and when it is detected that the target beverage is not taken away by the user, the step S270 is entered.
S260: and ending the flow.
S270: if the target beverage has not been removed by the user when the internal temperature of the target beverage has decreased to a minimum, the refrigeration of the compartment in which the target beverage is located is stopped.
After the prompt message is sent in step S240, if the target beverage is not taken away by the user, the refrigerator will refrigerate the compartment where the target beverage is located, and then the internal temperature of the target beverage will decrease, and when the internal temperature of the target beverage decreases to the minimum value of the preset temperature range, which is the limit value of the internal temperature, the refrigeration of the compartment where the target beverage is located is stopped.
In other embodiments, when it is detected that the target beverage is not taken away by the user after a preset time (for example, after 5 minutes) from the time when the prompt message is sent, the refrigeration of the compartment where the target beverage is located may be stopped.
S280: when the internal temperature of the target beverage increases to a maximum value, the compartment in which the target beverage is located continues to be refrigerated, and the step of monitoring the surface temperature of the target beverage and the ambient temperature in which the target beverage is located continues to be performed.
After the cooling is stopped in step S270, the internal temperature of the target beverage is increased, and when the internal temperature is increased to the maximum value of the preset temperature range, the cooling of the compartment where the target beverage is located is continued, so that the internal temperature of the target beverage is maintained within the preset temperature range. And meanwhile, while refrigerating the compartment where the target beverage is located continuously, returning to continue to execute the step S210 until the user takes the target beverage out of the refrigerator.
In other embodiments, the target beverage compartment may be continuously refrigerated after a preset time (e.g., after 5 minutes) from the stop of refrigeration, and the step of monitoring the surface temperature of the target beverage and the ambient temperature of the target beverage may be continuously performed.
Meanwhile, in the embodiment, in order to allow the user to receive the prompt information sent by the refrigerator in time, the user may send a trigger signal to a terminal that is in communication connection with the refrigerator in advance, such as a mobile phone and a tablet personal computer that the user carries with him, so that the terminal sends the first prompt information after receiving the trigger signal, in order that the user may leave the vicinity of the refrigerator after putting the beverage into the refrigerator and the prompt information sent by the refrigerator may not be received by the user in time.
The communication connection between the terminal and the refrigerator may be established through bluetooth connection, WIFI (Wireless Fidelity) connection, or other connection, which is not limited herein.
After receiving the trigger signal sent by the refrigerator, the terminal may remind the user in a short message, an incoming call, or the like, which is not limited herein.
In an application scene, if a plurality of beverages which are simultaneously placed in the same compartment of the refrigerator and have completely the same packaging material and surface temperature are monitored, if a user subsequently detects that only one target beverage is taken away, the temperature of other target beverages can be continuously controlled according to the method.
Wherein, in any one of the above embodiments, the method for controlling the temperature of the beverage further comprises:
obtaining a size of the target beverage based on the temperature in the compartment monitored by the plurality of infrared sensors; and adjusting the refrigerating air speed in the compartment where the target beverage is located according to the size of the target beverage and the surface temperature of the target beverage.
Specifically, during the whole refrigeration process of the refrigerator, the refrigerator intelligently adjusts the refrigeration wind speed according to the size of the target beverage (the method for obtaining the size of the target beverage can be referred to in the above embodiment) and the surface temperature of the target beverage, for example, if the target beverage has a large volume and a large surface temperature, the refrigeration wind speed is increased, and if the target beverage has a small volume and a low surface temperature, the refrigeration wind speed is decreased, so as to achieve the purpose of saving electricity and energy.
