Description

Technical Field

[0001] This application relates to the field of refrigerators, and in particular to refrigerator-based methods, apparatus, refrigerators, and storage media for making smoothies. Background Technology

[0002] As consumers demand more convenient and multifunctional home appliances, appliance manufacturers are choosing to integrate smoothie-making functions into refrigerators to meet consumers' needs for quickly and easily making various smoothie drinks at home.

[0003] In related technologies, time or temperature detection is used to determine whether a smoothie is ready. The time-control method requires setting a fixed time based on experience. The smoothie-making device runs a stirring program according to this fixed time, and the smoothie is considered ready when the stirring program completes. However, in home smoothie making, the initial temperature of the ingredients is often inconsistent; and the operating power of the smoothie-making device changes over time. These factors affect the time required for smoothie making, leading to a low success rate for refrigerators using a fixed time. Temperature detection monitors the temperature change of the mixture using a temperature sensor, and the smoothie is considered ready when it reaches a specific temperature. However, temperature variations at different locations during smoothie formation also contribute to the low success rate of refrigerator-made smoothies.

[0004] There is currently no effective solution to the problem of low success rate in making smoothies using refrigerators in related technologies. Summary of the Invention

[0005] Therefore, it is necessary to provide a refrigerator-based method, apparatus, refrigerator, and storage medium that can solve the problem of low success rate in making smoothies using a refrigerator, in order to address the aforementioned technical issues.

[0006] Firstly, this embodiment provides a refrigerator-based method for preparing smoothies. The refrigerator's target compartment is equipped with a smoothie-making device, which includes an ultrasonic generator and an ultrasonic receiver. The ultrasonic generator applies an ultrasonic signal to a container storing the smoothie, and the ultrasonic receiver receives the ultrasonic signal after it passes through the container. The method includes:

[0007] When the container is placed in the target chamber, the ice-making device is activated, and the time interval required for the ultrasonic generator to transmit to the ultrasonic receiver and the signal strength of the ultrasonic signal received by the ultrasonic receiver are obtained.

[0008] Determine whether the ratio between the second time interval acquired at the current moment and the first time interval acquired at the initial moment when the ice-making device is started is less than or equal to a first preset threshold, and whether the ratio between the second signal strength acquired at the current moment and the first signal strength acquired at the initial moment is less than or equal to a second preset threshold;

[0009] If the ratio between the second time interval and the first time interval is less than or equal to the first preset threshold, and the ratio between the second signal strength and the first signal strength is less than or equal to the second preset threshold, the ice-making device shall be stopped.

[0010] In one embodiment, activating the smoothie maker when the container is placed in the target chamber includes:

[0011] Obtain the temperature range within which the liquid used to make smoothies cannot trigger a phase transition under conditions of no condensation nuclei and no external interference;

[0012] When the container is placed in the target chamber, the temperature of the target chamber is adjusted to a first temperature, wherein the first temperature is within the temperature range;

[0013] Upon detecting that the temperature of the container has reached the first temperature, the ice-making device is activated, and the first time interval and the second time interval are acquired.

[0014] In one embodiment, after acquiring the first time interval and the first signal strength, the method further includes:

[0015] Stop operating the ice-making device;

[0016] Obtain the freezing point temperature of the liquid used to prepare the smoothie;

[0017] If the temperature of the container is detected to have reached the freezing point, the ice-making device is restarted, and the second time interval and the second signal strength are acquired until the ice-making device stops operating.

[0018] In one embodiment, after stopping the operation of the smoothie maker, the method further includes:

[0019] Obtain the freezing point temperature of the liquid used to prepare the smoothie;

[0020] The temperature of the target chamber is controlled to fluctuate periodically within a range above the freezing point and below zero.

[0021] In one embodiment, obtaining the freezing point temperature of the liquid used to prepare the smoothie includes:

[0022] When the container is placed in the target chamber, the temperature of the target chamber is adjusted to a first temperature; wherein, the first temperature is the temperature at which the liquid in the container is in a state without condensation nuclei and cannot trigger a phase change.

[0023] After the temperature of the container drops to the first temperature, if the temperature of the container rises and the temperature rise within a preset time period is greater than a preset value, then the temperature value is increased based on the first temperature to obtain the freezing point temperature.

[0024] In one embodiment, the refrigerator includes a compartment for storing the container, the ultrasonic generator is disposed at the bottom of the target compartment, and the ultrasonic receiver is movably disposed at the top of the target compartment. Activating the smoothie maker when the container is placed in the target compartment includes:

[0025] With the container placed in the target chamber, move the ultrasonic receiver until it contacts the container, and start the ice smoothie maker.

[0026] Secondly, this embodiment provides a refrigerator-based slush preparation device. The refrigerator's target compartment is equipped with a slush-making device, which includes an ultrasonic generator and an ultrasonic receiver. The ultrasonic generator applies an ultrasonic signal to a container storing slush, and the ultrasonic receiver receives the ultrasonic signal after it passes through the container. The device includes:

[0027] The acquisition module is used to activate the ice-making device when the container is placed in the target chamber, and to acquire the time interval required for the ultrasonic generator to transmit to the ultrasonic receiver and the signal strength of the ultrasonic signal received by the ultrasonic receiver.

[0028] The judgment module is used to determine whether the ratio between the second time interval obtained at the current time and the first time interval obtained at the initial time when the ice-making device is started is less than or equal to a first preset threshold, and whether the ratio between the second signal strength obtained at the current time and the first signal strength obtained at the initial time is less than or equal to a second preset threshold.

[0029] The control module stops operating the ice-making device when the ratio between the second time interval and the first time interval is less than or equal to the first preset threshold, and the ratio between the second signal strength and the first signal strength is less than or equal to the second preset threshold.

[0030] Thirdly, this embodiment provides a refrigerator, which includes a target compartment, a control device, and an ice-making device. The ice-making device is disposed in the target compartment and includes an ultrasonic generator and an ultrasonic receiver; wherein,

[0031] The ultrasonic generator is used to apply ultrasonic signals to the container storing the smoothie;

[0032] The ultrasonic receiver is used to receive ultrasonic waves that are output after passing through the container;

[0033] The control device is used to perform the refrigerator-based smoothie preparation method described in the first aspect above.

[0034] In one embodiment, the refrigerator further includes a temperature sensor for acquiring the temperature of the container used to store smoothies within the target compartment.

[0035] Fourthly, this embodiment provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the refrigerator-based smoothie preparation method described in the first aspect above.

[0036] The aforementioned method, apparatus, refrigerator, and storage medium for preparing slushies based on a refrigerator, determine whether the slushie is ready and stop the slushie-making device based on the change in the time interval between the signal from the ultrasonic generator to the ultrasonic receiver during the operation of the slushie-making device, as well as the change in the signal intensity received by the ultrasonic receiver. This improves the accuracy of determining whether the slushie is ready under different environments and ensures that the refrigerator can successfully prepare slushies. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0045] The method embodiments provided in this example can be executed on a terminal, computer, or similar computing device. For example, it can run on a terminal. Figure 1 This is a hardware structure block diagram of a terminal for a refrigerator-based smoothie preparation method according to an embodiment of this application. Figure 1 As shown, a terminal may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 and a memory 104 for storing data are also included. The processor 102 may be, but is not limited to, a microprocessor (MCU) or a programmable logic device (FPGA). The terminal may also include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that… Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the terminal described above. For example, the terminal may also include components that are larger than... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown are illustrated.

[0046] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the refrigerator-based smoothie preparation method in this embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the above-described method. The memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0047] The transmission device 106 is used to receive or send data via a network. This network includes a wireless network provided by the terminal's communication provider. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 can be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0048] In one embodiment, such as Figure 2 As shown, a refrigerator-based method for preparing smoothies is provided. The refrigerator's target compartment is equipped with a smoothie-making device, which includes an ultrasonic generator and an ultrasonic receiver. The ultrasonic generator applies an ultrasonic signal to a container storing the smoothie, and the ultrasonic receiver receives the ultrasonic signal output after passing through the container. The method includes the following steps:

[0049] Step 202: With the container placed in the target chamber, start the ice-making device and obtain the time interval required for the ultrasonic generator to transmit to the ultrasonic receiver and the signal strength of the ultrasonic signal received by the ultrasonic receiver.

[0050] The container is used to hold the liquid used to make the smoothie. The smoothie maker uses high-frequency mechanical vibration to apply energy to the container, utilizing the cavitation effect of the liquid inside to crystallize and transform it into smoothie. Traditional smoothie makers use instantaneous contact cooling, requiring a high cooling capacity per unit time, thus demanding high cooling capacity or instantaneous power from the device; furthermore, smoothie makers have requirements regarding sugar content. Water with low sugar content is more likely to cause large ice blocks to form, overloading the smoothie maker's motor and leading to smoothie failure. Step 202 uses a smoothie maker device including an ultrasonic generator and an ultrasonic receiver to replace the traditional smoothie maker, which reduces the requirement for liquid sugar content and also reduces the power required to make smoothie.

[0051] Optionally, the placement of the container in the target compartment can be detected by devices such as gravity sensors or image sensors, or by instructions input by the user into the refrigerator.

[0052] Step 204: Determine whether the ratio between the second time interval obtained at the current time and the first time interval obtained at the initial time when the ice-making device is started is less than or equal to a first preset threshold, and whether the ratio between the second signal strength obtained at the current time and the first signal strength obtained at the initial time is less than or equal to a second preset threshold.

[0053] In step 202, the time intervals acquired include a first time interval and a second time interval, and the signal strengths acquired in step 202 include a first signal strength and a second signal strength. The first time interval at the initial moment is the first time interval acquired at the start of the slush-making device, and the first signal strength at the initial moment is the first signal strength acquired at the start of the slush-making device. The second time interval includes one or more time intervals acquired after the initial moment, and the second signal strength includes one or more signal strengths acquired after the initial moment. Optionally, the first time interval and the second time interval are calculated based on the difference between the time when the ultrasonic generator actually emits the signal and the time when the ultrasonic receiver actually receives the signal.

[0054] The first and second preset thresholds are pre-set values. Ultrasonic waves travel at varying speeds and dynamic viscosities in liquids at different temperatures, causing variations in the transmission time and signal intensity of the ultrasonic signal within the same liquid and along the same path. For example, liquid A has a propagation speed of 1500 m / s at approximately 25 degrees Celsius, but only about 1400 m / s at approximately 0 degrees Celsius. Simultaneously, the dynamic viscosity of liquid A increases significantly at low temperatures, enhancing the absorption of ultrasonic energy through viscosity and thus weakening the signal intensity. Since the attenuation of time intervals and signal intensity differs between liquids during the transformation from liquid to slush, various liquids that could be used to make slush can be tested to observe the attenuation of ultrasonic signals in terms of time intervals and signal intensity during this transformation. Optionally, through experimentation, the ratio between the time interval corresponding to the liquid with the greatest attenuation and the time interval in the slush state is selected as the first preset threshold; similarly, the ratio between the signal intensity corresponding to the liquid with the greatest signal intensity attenuation and the signal intensity in the slush state is selected as the second preset threshold. Alternatively, first and second preset thresholds can be obtained for different types of liquids during the process of changing from a liquid state to a slushie, resulting in multiple sets of corresponding first and second preset thresholds. The ratio of the judgment time interval to the signal strength is then compared with the first and second preset thresholds within the same set.

[0055] Step 208: If the ratio between the second time interval and the first time interval is less than or equal to the first preset threshold, and the ratio between the second signal strength and the first signal strength is less than or equal to the second preset threshold, the ice-making device is stopped.

[0056] Optionally, when a first preset threshold is obtained based on the ratio of the time intervals with the greatest attenuation, and a second preset threshold is obtained based on the ratio of the signal strength with the greatest attenuation, the determination method is as follows: if the ratio between the second time interval and the first time interval is less than or equal to the first preset threshold, and the ratio between the second signal strength and the first signal strength is less than or equal to the second preset signal strength, it is determined that the liquid in the container has been prepared into a slushie. When multiple sets of corresponding first and second preset thresholds are obtained, the determination method is as follows: if the ratio of the time intervals is less than or equal to the first preset threshold, and the ratio of the signal strengths is less than the second preset threshold in the same set as the first preset threshold, it is determined that the liquid has been prepared into a slushie.

[0057] Optionally, after the smoothie maker stops operating, a notification indicating that the smoothie preparation is complete can be sent to the user via one or more methods, such as a preset sound signal, a display screen embedded in the refrigerator, or a smartphone app paired with the refrigerator. Optionally, the ultrasonic generator and ultrasonic receiver can also be stopped when the smoothie maker stops operating.

[0058] In the aforementioned refrigerator-based slush preparation method, a dynamic, relatively comparative judgment method is constructed based on the changing characteristics of signal transmission time intervals and signal intensity attenuation during the slush preparation process. The method determines whether the slush preparation is complete and stops operating the slush-making device based on the judgment result. Compared to traditional methods that determine slush preparation completion based on fixed time or temperature thresholds, this method automatically adapts to different time intervals and signal intensity starting points, avoiding the need to set fixed thresholds for different systems or application scenarios. This improves adaptability to factors such as equipment differences, environmental changes, and individual differences, thereby increasing the accuracy of judging whether the refrigerator has completed slush preparation and ensuring successful slush production.

[0059] In one embodiment, when the container is placed in the target chamber, activating the slush-making device includes: obtaining the temperature range in which the liquid used to make the slush cannot trigger a phase change state under conditions of no condensation nuclei and no external interference; when the container is placed in the target chamber, adjusting the temperature of the target chamber to a first temperature, wherein the first temperature is within the temperature range; and when the temperature of the container is detected to have reached the first temperature, activating the slush-making device and obtaining a first time interval and a second time interval.

[0060] Phase transition refers to the process by which a substance changes from one phase to another. Condensation nuclei are solid, liquid, and gaseous aerosol particles that act as condensation nuclei during the condensation process. Optionally, under conditions without condensation nuclei and without external interference, experiments are conducted on various liquids used to make smoothies to obtain the common temperature range within which these liquids remain liquid without undergoing a phase transition. A temperature within this range can be pre-selected as the first temperature based on requirements and the refrigerator's cooling capacity.

[0061] In this embodiment, the temperature of the target chamber where the container is stored is adjusted to a first temperature. When the container in the target chamber cools down from room temperature to the first temperature and the container temperature reaches the first temperature, the first time interval and the first signal intensity of the initial propagation of the ultrasonic wave are recorded by an ultrasonic generator and an ultrasonic receiver. This reduces the impact of different temperature environments on the accuracy of the judgment results when judging the time interval and signal intensity.

[0062] Furthermore, in one embodiment, after acquiring the first time interval and the first signal strength, the method further includes: stopping the operation of the slush-making device; acquiring the freezing point temperature of the liquid used to prepare the slush; and restarting the slush-making device when the temperature of the container is detected to have reached the freezing point temperature, and acquiring the second time interval and the second signal strength until the slush-making device stops operating.

[0063] When the container temperature rises from a lower initial temperature to its freezing point, the medium inside the container readily and rapidly melts some of the ice crystals, thus producing slush under the action of the slush-making device. Once the container temperature is detected to have reached its freezing point, the slush-making device is restarted. This allows the liquid inside the container to respond to the ultrasonic waves output by the device, rapidly changing its state and thus producing slush, improving the success rate of slush preparation and reducing energy consumption.

[0064] In one embodiment, after stopping the operation of the slush-making device, the method further includes: obtaining the freezing point temperature of the liquid used to prepare the slush; and controlling the target compartment temperature of the storage container to periodically fluctuate within a range above the freezing point and below zero degrees Celsius.

[0065] The fluctuation period is a preset time length, which can optionally be set to any value between 2 minutes and 4 hours, depending on the experiment. After successful slush preparation, if the slush is stored above its freezing point, it easily melts into a liquid; if stored below its freezing point, it easily solidifies, affecting its texture and success rate. Furthermore, considering that water molecules easily melt into a liquid at temperatures above or equal to zero degrees Celsius and easily freeze at temperatures below or equal to zero degrees Celsius, this embodiment controls the temperature of the target storage compartment within the range above and below freezing after stopping the slush-making device, allowing for longer slush storage.

[0066] The freezing point temperature of the liquid can be selected from a preset temperature obtained experimentally. To further improve the success rate of slush preparation, the freezing point temperature can also be determined by the change in container temperature. In one embodiment, obtaining the freezing point temperature of the liquid used to prepare slush includes: with the container placed in the target chamber, adjusting the temperature of the target chamber to a first temperature; wherein, the first temperature is the temperature at which the liquid in the container is in a state without condensation nuclei and cannot trigger a phase change; after the container temperature drops to the first temperature, if the container temperature rises and the temperature rise within a preset time period is greater than a preset value, then the temperature is increased by a value based on the first temperature to obtain the freezing point temperature.

[0067] In this process, as the container temperature drops from room temperature to a first temperature, the liquid inside gradually transforms into a slush. During this process, the latent heat of the supercooled liquid at the first temperature is released, causing the container temperature to rise until it reaches the freezing point. The time period corresponding to the release of latent heat from the supercooled liquid can be determined experimentally and used as a preset time period; the magnitude of the temperature rise in the container can be used as a preset value.

[0068] Optionally, after adjusting the temperature of the target chamber to a first temperature, wait for the container temperature to drop to the first temperature and run the ice-making device; after acquiring the first time interval and the first signal strength, turn off the ice-making device; if the container temperature rises and the temperature rise of the container within a preset time period is greater than a preset value, increase the temperature value based on the first temperature to obtain the freezing point temperature; when the container temperature reaches the freezing point temperature, turn the ice-making device back on and acquire the second time interval and the second signal strength.

[0069] This embodiment determines whether the container temperature is affected by the release of latent heat by setting a preset time period and a preset change value, and calculates the accurate freezing point temperature based on this.

[0070] In one embodiment, an ultrasonic generator is disposed at the bottom of the target chamber, and an ultrasonic receiver is movably disposed at the top of the target chamber. Activating the smoothie maker when the container is placed in the target chamber includes: moving the ultrasonic receiver until it contacts the container, thereby activating the smoothie maker.

[0071] By moving the ultrasonic receiver to contact the top surface of the container, the possibility of external interference during ultrasonic wave propagation is avoided, thereby improving the signal strength received by the ultrasonic receiver and the accuracy of the time interval calculated based on the ultrasonic generator and the ultrasonic receiver.

[0072] In one embodiment, Figure 3 A refrigerator is provided, comprising a target compartment, a control device, and an ice-making device. The ice-making device is disposed in the target compartment and includes an ultrasonic generator and an ultrasonic receiver. The ultrasonic generator applies an ultrasonic signal to a container storing ice-smoothies; the ultrasonic receiver receives the ultrasonic waves emitted after passing through the container; and the control device executes the steps described in the above-described method embodiments. The ultrasonic generator and ultrasonic receiver are disposed opposite each other on opposite sides of the container. Optionally, the ultrasonic generator and ultrasonic receiver can be disposed on the upper and lower sides of the container, or on the left and right sides of the container, etc. The specific installation positions of the ultrasonic generator and ultrasonic receiver are not limited herein.

[0073] Optionally, the refrigerator also includes a temperature sensor for acquiring the temperature of the container inside the target compartment used to store smoothies.

[0074] In one embodiment, Figure 4 A schematic diagram of the target compartment of a refrigerator is provided, such as... Figure 4 As shown, the ultrasonic generator is located at the bottom of the target chamber, the ultrasonic receiver is movably located at the top of the target chamber, the infrared temperature sensor is located on the side wall of the target chamber, and a gravity sensor is also located at the bottom of the target chamber. Optionally, the infrared temperature sensor can also be located at other locations where the container temperature can be detected; this is not limited to these locations.

[0075] Figure 5 A flowchart illustrating a method for making smoothies in a refrigerator is provided, which can be applied to... Figure 4 In the target compartment of the refrigerator shown, taking a beverage bottle as an example, such as... Figure 5 As shown, it includes the following steps:

[0076] Step 501: After the gravity sensor detects that a beverage bottle has been placed in the target chamber, the ultrasonic receiver moves downwards until it contacts the top of the beverage bottle. Optionally, the distance L from the generator to the receiver can be determined based on the distance the ultrasonic receiver moves.

[0077] Step 502: The target chamber temperature is controlled at a first temperature t1; the first temperature is within the temperature range of t1 < -2 degrees Celsius. Specifically, at temperature t1, if the beverage in the bottle is in a state without condensation nuclei and in an undisturbed environment, the beverage in the bottle remains liquid and a phase change cannot be triggered. Optionally, temperature t1 can preferably be selected from a temperature range of -5 degrees Celsius to -10 degrees Celsius.

[0078] Step 503: When the infrared temperature sensor detects that the temperature of the beverage bottle in the target chamber has dropped from room temperature to temperature t1 and is maintained at this temperature, the ice smoothie maker is started, the ultrasonic receiver records the first time interval T0 and the first signal intensity A0 of the ultrasonic signal propagation, and the ice smoothie maker is turned off.

[0079] Step 504: When the temperature of the beverage bottle rises by ΔT within a 1-minute time period, and ΔT is greater than 3 degrees Celsius, the freezing point temperature t2 is calculated as t2 = t1 + ΔT. After the infrared sensor detects that the beverage bottle temperature has risen from t1 to its freezing point temperature t2, the ice-making device is activated until the ultrasonic generator and ultrasonic receiver record the second time interval of ultrasonic wave propagation. And the second signal strength In step 504, the temperature of the target chamber is controlled at t1; the first preset threshold is 0.8, and the second preset threshold is 0.5. The first preset threshold can be calculated based on the difference in the propagation speed between sound and ice sand and liquid; the second preset threshold can be obtained through experimental data testing, and the first and second preset thresholds can also be set to other values.

[0080] Step 505: Increase the temperature of the target chamber and control the temperature of the target chamber to fluctuate within a preset period between 0 and (t2-1) degrees Celsius to ensure the smoothie is preserved in the target chamber for a long time. The temperature fluctuation period of the target chamber can be selected from a time length between 2 minutes and 4 hours. The fluctuation period can also be obtained experimentally.

[0081] Based on the same inventive concept, this application also provides an apparatus for implementing the refrigerator-based smoothie preparation method described above. The solution provided by this apparatus is similar to the solution described in the above method; therefore, the specific limitations in one or more refrigerator-based smoothie preparation apparatus embodiments provided below can be found in the limitations of the refrigerator-based smoothie preparation method described above, and will not be repeated here.

[0082] In one embodiment, such as Figure 6 As shown, a refrigerator-based slush preparation device is provided. The target compartment of the refrigerator is equipped with a slush-making device, which includes an ultrasonic generator and an ultrasonic receiver. The ultrasonic generator applies an ultrasonic signal to a container storing slush, and the ultrasonic receiver receives the ultrasonic signal output after passing through the container. The device includes:

[0083] The acquisition module is used to start the ice-making device when the container is placed in the target chamber, and to acquire the time interval required for the ultrasonic generator to transmit to the ultrasonic receiver and the signal strength of the ultrasonic signal received by the ultrasonic receiver.

[0084] The judgment module is used to determine whether the ratio between the second time interval obtained at the current time and the first time interval obtained at the initial time when the ice-making device is started is less than or equal to a first preset threshold, and whether the ratio between the second signal strength obtained at the current time and the first signal strength obtained at the initial time is less than or equal to a second preset threshold.

[0085] The control module stops operating the ice-making device when the ratio between the second time interval and the first time interval is less than or equal to the first preset threshold, and the ratio between the second signal strength and the first signal strength is less than or equal to the second preset threshold.

[0086] In one embodiment, the acquisition module, when a container is placed in a target chamber, activates the slush-making device by: acquiring the temperature range in which the liquid used to make slush cannot trigger a phase transition state under conditions of no condensation nuclei and no external interference; adjusting the temperature of the target chamber to a first temperature when the container is placed in the target chamber, wherein the first temperature is within the temperature range; and activating the slush-making device when the temperature of the container is detected to have reached the first temperature, and acquiring a first time interval and a first signal strength.

[0087] Optionally, after acquiring the first time interval and the first signal strength, the acquisition module is further configured to: stop the operation of the slush-making device; acquire the freezing point temperature of the liquid used to prepare the slush; and restart the slush-making device when the temperature of the container is detected to have reached the freezing point, and acquire the second time interval and the second signal strength until the slush-making device stops operating.

[0088] In one embodiment, after the slush-making device is stopped, the control module is also used to obtain the freezing point temperature of the liquid used to prepare the slush; and to control the temperature of the target chamber to fluctuate periodically within a range above the freezing point and below zero degrees.

[0089] In one embodiment, the control module or acquisition module acquires the freezing point temperature of the liquid used to prepare the slush by: adjusting the temperature of the target chamber to a first temperature when the container is placed in the target chamber; wherein, the first temperature is the temperature at which the liquid in the container cannot trigger a phase change state under the condition that there are no condensation nuclei and the phase change state cannot be triggered; after the temperature of the container drops to the first temperature, if the temperature of the container rises and the temperature rise of the container within a preset time period is greater than a preset value, then the temperature value is increased based on the first temperature to obtain the freezing point temperature.

[0090] In one embodiment, an ultrasonic generator is disposed at the bottom of the target chamber, and an ultrasonic receiver is movably disposed at the top of the target chamber. When the container is placed in the target chamber, the activation of the smoothie-making device by the acquisition module includes: moving the ultrasonic receiver until it contacts the container, thereby activating the smoothie-making device.

[0091] Each module in the aforementioned refrigerator's smoothie preparation device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device, or stored in the computer device's memory as software, so that the processor can call and execute the corresponding operations of each module.

[0092] In one embodiment, a computer device is provided, which may be a terminal, and its internal structure diagram may be as follows: Figure 7 As shown, the computer device includes a processor, memory, input / output interface, communication interface, display unit, and input device. The processor, memory, and input / output interface are connected via a system bus, and the communication interface is also connected to the system bus via the input / output interface. The processor provides computing and control capabilities. The memory includes a non-volatile storage medium and internal memory. The non-volatile storage medium stores the operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs stored in the non-volatile storage medium. The input / output interface is used for exchanging information between the processor and external devices.
