Technical Field

[0001] The present application relates to the field of refrigerators, and in particular to a refrigerator and a control method thereof. Background Art

[0002] With the continuous development of refrigerator technology, refrigerators have gradually evolved from single refrigeration equipment to multifunctional household appliances that integrate ice making, defrosting, and preservation, providing convenience for users.

[0003] However, conventional defrosting and ice-making functions usually rely solely on ambient temperature, have low working efficiency, and produce unsatisfactory defrosting and ice-making effects. Summary of the Invention

[0004] Based on this, it is necessary to provide a refrigerator and a control method thereof to address the above technical problems, so as to improve work efficiency.

[0005] In a first aspect, some embodiments provide a refrigerator comprising:

[0006] A box body having a storage space inside for storing the target object;

[0007] an ultrasonic transducer disposed in the storage space and configured to emit ultrasonic waves into the storage space;

[0014] Determining a target duty cycle that matches the target object temperature based on a second preset matching relationship;

[0015] controlling the ultrasonic transducer to emit ultrasonic waves according to target power and target duty cycle to defrost the target object;

[0016] When the temperature of the target object is not less than a preset temperature threshold, the ultrasonic transducer is controlled to be turned off.

[0017] In the above-mentioned embodiment, by introducing an ultrasonic transducer to thaw the target object, the cavitation effect and mechanical effect generated by the high-frequency vibration of ultrasound can be used to act on the ice crystals of the target object, accelerating the breakage and melting of the ice layer, which is beneficial to improving the thawing efficiency. At the same time, the ultrasonic energy can penetrate the inside and outside of the target object to achieve synchronous thawing and reduce local overheating or nutrient loss. By obtaining the target weight and target temperature of the target object, a data basis is provided for the dynamic regulation of subsequent thawing control. By introducing a first preset matching relationship and a second preset matching relationship, the target power that matches the target weight and the target duty cycle that matches the target object temperature can be quickly determined.

[0080] Figure 1 is a block diagram of a refrigerator according to one embodiment of the present invention.

[0081] like Figure 1 As shown, the refrigerator 100 includes a cabinet 1 .

[0082] In some embodiments, the housing 1 is the external structure of the refrigerator 100, providing physical protection for the internal space of the refrigerator 100, that is, it can protect the internal refrigeration components and food from external environmental influences, such as dust, moisture, collisions, etc. Through the thermal insulation material, the housing 1 can effectively isolate the temperature difference between the inside of the refrigerator 100 and the outside world, reduce refrigeration losses, and ensure the refrigeration and freezing effects in the refrigerator 100. In addition, the housing 1 provides structural support for the various components of the refrigerator 100 (such as the compressor, condenser 22, and heat exchange subsystem), so that the entire refrigerator 100 can operate stably. The refrigerator 100 also includes a door body, which is connected to the housing 1.

[0083] like Figure 2 As shown, refrigerator 100 also includes a storage compartment, which is located within housing 1. Storage compartments include refrigerators and / or freezers. Housing 1 is constructed with at least a refrigerator 11 and a freezer 12, each with different functional areas, to meet the user's storage needs for different foods. Refrigerator 11 is an independent space within refrigerator 100 suitable for storing foods that do not require refrigeration but require low-temperature storage, such as vegetables, fruits, beverages, and dairy products. By maintaining a low temperature range, the shelf life of the food can be effectively extended. The temperature within refrigerator 11 can be maintained between 2°C and 8°C, and the specific temperature can be adjusted according to the type of food. Freezer 12 is another independent space within refrigerator 100 suitable for storing meat, seafood, and frozen foods. Freezer 12 can quickly freeze food, preserving its nutrients, and can also be used to make ice cubes and frozen drinks. Freezer 12 can maintain a temperature of -18°C or lower. By maintaining a low temperature environment, it freezes food, preventing bacterial growth and spoilage, and extending its shelf life.

[0084] like Figure 1 As shown, the refrigerator 100 further includes a refrigeration system 2 .

[0085] In some embodiments, the refrigeration system 2 is the core functional module of the refrigerator 100. Its function is to transfer the heat inside the refrigerator 100 to the outside through the circulation of the refrigerant, thereby realizing the refrigeration and freezing functions, ensuring the freshness of refrigerated food and the long-term preservation of frozen food.

[0086] Figure 3 is a schematic diagram of a refrigeration system according to an embodiment of the present invention. Figure 3 As shown, the refrigeration system 2 includes a compressor 21, a fan, a condenser 22, a refrigeration compartment heat exchange subsystem, and a freezer compartment heat exchange subsystem.

[0087] In some embodiments, the compressor 21 is one of the core components of the refrigeration system 2. It compresses the refrigerant to increase its pressure and promotes the refrigerant to circulate within the refrigeration system 2. The refrigerant exchanges heat through various heat exchange subsystems, thereby achieving a cooling effect.

[0088] In some embodiments, a fan is a device used to promote air flow in the refrigeration system 2. It can be driven by an electric motor and can generate airflow through rotating blades to help circulate cold air inside and outside the refrigerator 100. The type of fan can be centrifugal or axial, depending on the design requirements.

[0089] In some embodiments, the fan's primary function is to propel cold air throughout the refrigerator 100, ensuring even distribution of cool air to every corner of the refrigerator compartment 11 and freezer compartment 12, thereby improving cooling efficiency. Within the condenser 22, the fan helps improve heat exchange efficiency. It exhausts hot air surrounding the condenser 22, enabling the condenser 22 to more efficiently cool the refrigerant and convert it to a liquid state. Furthermore, the fan can also help prevent frost accumulation to a certain extent. By enhancing air flow and reducing moisture accumulation, the fan can slow the formation of frost within the refrigerator 100.

[0090] In some embodiments, the condenser 22 is an important component of the refrigeration system 2. Its function is to cool the high-temperature and high-pressure gaseous refrigerant and condense it into a high-pressure liquid refrigerant. The condenser 22 dissipates the heat in the refrigerant by exchanging heat with the outside air.

[0091] In some embodiments, the condenser 22 can be air-cooled or water-cooled. For air-cooled condensers, the condenser 22 may have multiple fins on its surface to increase the contact area with the air and enhance heat dissipation efficiency. In some high-end or special-purpose refrigerators 100, a water-cooled condenser may be used. Cooling water removes heat, further improving condensation efficiency, especially in hot environments.

[0092] In some embodiments, the refrigerator compartment heat exchange subsystem may refer to a component used to transfer cold air to the interior of the refrigerator compartment 11. The refrigerator compartment heat exchange subsystem may include a refrigerator compartment evaporator 23, which functions to lower the temperature of the refrigerator compartment 11 through the refrigerant's vaporization and heat absorption process as low-temperature, low-pressure refrigerant flows through the refrigerator compartment evaporator 23. The refrigerator compartment evaporator 23 evenly distributes cold air, ensuring a uniform temperature within the refrigerator compartment 11, maintaining the temperature between 2°C and 8°C. This ensures that the temperature within the refrigerator compartment 11 is suitable for storing food that does not require refrigeration, thereby extending the shelf life of the food.

[0093] In some embodiments, the refrigerator compartment evaporator 23 can be made of a highly thermally conductive material, such as aluminum or copper. Aluminum evaporators are lightweight and offer excellent thermal conductivity, allowing them to quickly absorb heat from the refrigerator compartment 11 and ensure a uniform and stable temperature. Furthermore, the refrigerator compartment evaporator 23 can utilize a multi-layer coil structure, depending on the design of the refrigerator 100, to further enhance heat exchange.

[0094] In some embodiments, the freezer heat exchange subsystem may include a freezer evaporator 24, which is responsible for transferring cold energy to the interior of the freezer 12. The freezer evaporator 24 absorbs heat from the freezer 12, ensuring that the temperature drops to -18°C or lower, ensuring that food is quickly frozen, thereby preventing food from spoiling and being suitable for long-term food storage.

[0095] In some embodiments, the freezer compartment evaporator 24 may be designed as a coil evaporator. The arrangement and surface area of ​​the freezer compartment evaporator 24 may vary depending on the design requirements of the freezer compartment 12. For freezers 12 requiring rapid freezing, the surface area and refrigerant flow rate of the freezer compartment evaporator 24 may be larger to ensure rapid cooling.

[0096] In some embodiments, the input port of the refrigerating chamber heat exchange subsystem and the input port of the freezing chamber heat exchange subsystem are respectively connected to the output port of the condenser 22 , and the input port of the condenser 22 is connected to the exhaust port of the compressor 21 .

[0097] like Figure 1 As shown, the refrigerator 100 further includes a controller 3 .

[0098] In some embodiments, controller 3 is the intelligent core of refrigerator 100, responsible for managing the operating status of refrigerator 100. It monitors sensor data from refrigerator 100 and makes adjustments based on the operating environment. In particular, under fault or abnormal conditions, controller 3 can control the operation of compressor 21 according to set logic. Both controller 3 and compressor 21 are located within the refrigerator.

[0099] In the embodiment of the present application, the controller may be a microcontroller unit (MCU) or other types of controllers. The embodiment of the present application does not specifically limit the controller.

[0100] In combination with the above content, the refrigerator also includes a main variable display integrated board, which is arranged in the box body, and the controller is arranged on the main variable display integrated board.

[0101] The internal structure of the main variable display integrated board in the refrigerator is as follows Figure 4 As shown, Figure 4 FIG. 1 is a schematic structural diagram of a main variable display integrated board and a compressor in a refrigerator according to some embodiments. Figure 4As shown, the refrigerator includes a main, variable, and display integrated board 101, a compressor 102, a fan 103, and a compartment temperature sensor. The main, variable, and display integrated board 101 includes a controller 201, a power filter circuit 202, a rectifier element 203, a voltage detection circuit 204, a three-phase inverter circuit 205, a drive circuit 206, a current sampling circuit 207, a memory 208, a voltage analog-to-digital conversion module 209, a pulse width modulation signal output module 2010, a temperature analog-to-digital conversion module 2011, an operational amplifier 2012, a key detection circuit 2013, a display drive circuit 2014, a display module 2015, a fan 103 drive circuit 206, and a fan interface 2017.

[0102] Figure 4 The mains power input is typically AC. Power filter circuit 202 stabilizes the DC voltage by leveraging the energy storage and release characteristics of capacitors. Rectifier element 203 converts AC power to DC. Three-phase inverter circuit 205 converts DC power to three-phase AC power, providing a suitable three-phase AC power source for compressor 102.

[0103] The voltage detection circuit 204 mainly detects the bus voltage through the voltage divider resistor and sends the detected voltage to the voltage analog-to-digital conversion module 209. The voltage analog-to-digital conversion module 209 converts the received voltage into a voltage signal so that the controller 201 can obtain the voltage signal in the voltage analog-to-digital conversion module 209. The current sampling circuit 207 samples the DC bus current and sends the collected current to the operational amplifier 2012. The operational amplifier 2012 processes the collected current and sends the processed current to the current analog-to-digital conversion module ( Figure 4 The current analog-to-digital conversion module converts the received current into a current signal, so that the controller 201 can obtain the current signal in the current analog-to-digital conversion module.

[0104] The controller 201 analyzes and processes the digital current signal to obtain a pulse width modulation (PWM) signal for controlling the operation of the compressor 102, and sends the PWM signal to the drive circuit 206 through the pulse width modulation signal output module 2010. The drive circuit 206 uses the PWM signal to control the output of the three-phase inverter circuit 205 to control the operating state of the compressor 102.

[0105] The memory 208 is used to store information such as the gear position of the refrigerator. The embodiment of the present application does not specifically limit the information that the memory 208 can store.

[0106] The temperature analog-to-digital conversion module 2011 is used to convert the temperature collected by the temperature sensor into a temperature signal, so that the controller 201 can obtain the temperature signal in the temperature analog-to-digital conversion module 2011 .

[0107] The key detection circuit 2013 is used to detect the status of the keys in real time and adjust the gear position and control mode of the refrigerator. The display driving circuit 2014 drives the display module 2015 to display the gear position and mode information.

[0108] It should be noted that the button is a button set on the refrigerator, and the user can set the temperature of the refrigerator, etc. by operating the button.

[0109] The fan 103 can be driven to operate the refrigerator fan 103 through the fan interface 2017.

[0110] like Figure 4 The controller can obtain information from the key detection circuit through the interface and transmit data to the display drive circuit and the fan drive circuit through the interface. Figure 4 The structure shown is only an example structure and does not constitute any limitation. Figure 4 The structure shown in FIG. 1 is a diagram illustrating a method for controlling the refrigerator by the controller during operation of the refrigerator.

[0111] With the continuous development of refrigerator technology, refrigerators have gradually evolved from simple refrigeration devices to multifunctional appliances that integrate ice making, defrosting, and freshness preservation, providing users with greater convenience. Traditional defrosting and ice making functions are often dependent solely on ambient temperature. For example, during the defrosting process, the refrigerator's defrosting temperature is often increased to achieve faster defrosting. However, setting the defrosting temperature too high can affect the taste of food and even lead to a loss of nutrients.

[0112] In order to overcome the above problems, in some optional embodiments, see Figure 5A , provides a refrigerator control method, which is applied to a controller in a refrigerator and may include the following steps:

[0113] S510: Obtain a thawing control instruction.

[0114] The thawing control instruction may be understood as a control instruction for thawing a target object in the storage space of the refrigerator.

[0115] In some embodiments, a defrost button may be provided on the housing 1 of the refrigerator 100. Accordingly, a defrost control instruction may be obtained in response to a triggering operation on the defrost button. The defrost button may be at least one of a touch button and a mechanical button. This application does not impose any restrictions on the specific installation location or button form of the defrost button.

[0116] In other embodiments, a defrost control instruction sent by a mobile terminal or a refrigerator remote control may be obtained.

[0117] In some other embodiments, a timer task may be set, and a thawing control instruction may be generated when a first timer task is triggered.

[0118] In some embodiments, the thawing control instruction may include an ultrasonic frequency of an ultrasonic transducer. Exemplarily, the ultrasonic frequency corresponding to the thawing control instruction may be 20KHZ-1MHz, so that the ultrasonic wave output by the ultrasonic transducer can generate tiny bubbles in the medium, and the shock wave generated by the bursting of the bubbles can destroy the ice crystal structure and accelerate thawing. At the same time, ultrasonic energy can penetrate inside and outside the food, reduce local overheating, and help improve the thawing effect. It is worth noting that the ultrasonic frequency corresponding to the thawing control instruction can be set by technical personnel according to needs or experience, or determined through a large number of experiments, and this application does not impose any restrictions on this.

[0119] S520. In response to the defrost control instruction, obtain the target weight and target temperature of the target object in the storage space of the refrigerator; wherein a temperature sensor, a weighing sensor and an ultrasonic transducer are provided in the storage space; the temperature sensor is used to collect the temperature of the target object; the weighing sensor is used to collect the target weight; and the ultrasonic transducer is used to transmit ultrasonic waves into the storage space.

[0120] The target object may include food, such as meat, seafood, frozen food, etc. This embodiment does not impose any limitation on the specific type of the target object.

[0121] In some embodiments, the storage space may be the storage space corresponding to the refrigerator compartment 11 or the freezer compartment 12, or the storage space inside the target container in the refrigerator compartment 11 or the freezer compartment 12. For example, the temperature sensor, the weighing sensor, and the ultrasonic transducer may be disposed in the refrigerator compartment 11 or the freezer compartment 12.

[0122] In some embodiments, a target container may be provided in the housing 1, and the target container may have the above-mentioned storage space formed therein. The target container may be provided in the refrigerator compartment 11 or the freezer compartment 12. For example, the target container may be provided in a refrigerated drawer of the refrigerator compartment 11. It should be noted that this embodiment does not impose any restrictions on the specific shape and specific setting position of the target container. For example, in other embodiments, the target container may also be installed on the door of the refrigerator 100, or be provided in the freezer compartment 12, or the target container may be a refrigerated drawer of the refrigerator compartment 11. For example, a temperature sensor, a weighing sensor, and an ultrasonic transducer may be provided in the target container.

[0123] Optionally, the bottom of the target container may be provided with a mounting portion for the ultrasonic transducer, which may be a mounting slot or hole. Placing the ultrasonic transducer at the bottom of the target container facilitates close contact between the target object and the transducer, thereby improving the thawing effect. Optionally, the weighing sensor may be positioned at the bottom edge of the target container to avoid affecting the aesthetics.

[0124] In some embodiments, a target container is disposed within the housing 1, with a storage space formed therein. A power port is disposed on the target container, and a connecting cable connecting the power port and the ultrasonic transducer is pre-embedded in the target container. Alternatively, connecting cables connecting the power port and a load cell, and / or connecting the power port and a temperature sensor, may be pre-embedded in the target container.

[0125] refer to Figure 5B Schematic diagram of the structure of the target container in some embodiments. Wherein, the target container 51 can be set in the refrigeration drawer a of the refrigeration chamber.

[0126] refer to Figure 5C The following is a schematic diagram of the structure of a refrigerated drawer in some embodiments. The bottom of refrigerated drawer A is provided with a first mounting slot 511 for mounting a target container 51 and a second mounting slot 512 for mounting an ultrasonic transducer. Refrigerated drawer A is provided with a power port 53. A connecting cable connecting the power port 53 and the ultrasonic transducer can be pre-embedded in refrigerated drawer A.

[0127] refer to Figure 5D Schematic diagram of the structure of the refrigerated drawer in some other embodiments. Wherein, the first mounting groove 511 and the second mounting groove 512 at the bottom of the refrigerated drawer a can be formed by being recessed outwards.

[0128] refer to Figure 5E Schematic diagrams of target containers in other embodiments are provided. Target container 51 can be placed in a refrigerator or freezer compartment of a container. A second mounting slot 512 for mounting an ultrasonic transducer is provided at the bottom of target container 51. A power port 53 is provided on target container 51. A connecting cable connecting power port 53 and the ultrasonic transducer can be pre-embedded in target container 51.

[0129] For example, a first container may be provided within the target container. The first container may be removably provided with an ice-making assembly for storing an ice-making medium. When thawing is required, the ice-making assembly is removed from the first container and the target object to be thawed is placed into the first container. When ice is required, the ice-making assembly is placed back into the first container.

[0130] S530: When the temperature of the target object is lower than a preset temperature threshold, determine a target power that matches the target weight based on a first preset matching relationship.

[0131] Among them, the preset temperature threshold can be set by technicians according to needs or experience, or determined through a large number of experiments, and this application does not impose any restrictions on this.

[0132] The first preset matching relationship may be understood as a preset matching relationship between different target weights and corresponding target powers.

[0133] In some embodiments, the first preset matching relationship may be a first relationship expression between the target weight and the target power. Accordingly, the target weight may be input into the first relationship expression to obtain the corresponding target power.

[0134] In other embodiments, the first preset matching relationship may be a first mapping relationship between different preset weight intervals and corresponding target powers. Accordingly, the target weight interval to which the target weight belongs may be determined; and based on the first mapping relationship, the target power matching the target weight interval may be searched.

[0135] In some further embodiments, the first preset matching relationship may include weight parameters corresponding to different preset weight intervals; accordingly, the target weight interval to which the target weight belongs can be determined from each preset weight interval; based on the first preset matching relationship, the target weight parameters corresponding to the target weight interval are searched; the preset reference power of the ultrasonic transducer is obtained; and the preset reference power is weighted with the weight parameters corresponding to the target weight interval to obtain the target power.

[0136] For example, when the target weight Q falls within the first weight interval [Q1, Q2], the weight parameter may be w1, and the target power P may be expressed as: w1*P1. Here, w1 represents the weight parameter; P1 represents the preset reference power; Q1 represents the first weight threshold; Q2 represents the second weight threshold; and Q2>Q1.

[0137] For example, when the target weight Q falls within the second weight interval [Q2, Q3], the weight parameter may be w2, and the target power P may be expressed as: W2*P1. Here, w2 represents the weight parameter; P1 represents the preset reference power; Q2 represents the second weight threshold; Q3 represents the third weight threshold; and Q3>Q2.

[0138] It is worth noting that the weight parameters, preset reference power and preset weight range can be set by technicians according to needs or experience, or determined through a large number of experiments. This embodiment does not impose any restrictions on this. For example, w1=1, W2=1.5.

[0139] S540. Determine a target duty cycle that matches the temperature of the target object based on the second preset matching relationship.

[0140] Among them, the second preset matching relationship can be understood as a pre-set matching relationship between different target object temperatures and corresponding target duty cycles.

[0141] Among them, the target duty cycle can be understood as the ratio of the time when the output of the ultrasonic transducer is at a high level (i.e., in an effective state) to the entire cycle time. For example, the pulse frequency of the ultrasonic transducer is to turn on for N1 seconds and turn off for N1 seconds, that is, the target duty cycle is 50%.

[0142] In some embodiments, the second preset matching relationship can be a relational expression between the target object temperature and the target duty cycle. Correspondingly, the target object temperature can be input into the relational expression to obtain the corresponding target duty cycle. Exemplarily, the higher the target object temperature, the smaller the corresponding target duty cycle.

[0143] In some other embodiments, the second preset matching relationship can be a mapping relationship between different preset temperature ranges and corresponding target duty cycles. Correspondingly, the target temperature range to which the target object temperature belongs can be determined, and based on the second preset matching relationship, the target duty cycle corresponding to the target temperature range can be found.

[0144] Exemplarily, when T < T1, the pulse frequency of the ultrasonic transducer can be to turn on for N1 seconds and turn off for N2 seconds, N1 = 3N2, that is, the target duty cycle is 75%. Where T represents the target object temperature; T1 represents the first temperature threshold.

[0145] Exemplarily, when T1 ≤ T < T2, the pulse frequency of the ultrasonic transducer can be to turn on for N1 seconds and turn off for N3 seconds, N1 = 2N3, that is, the target duty cycle is 67%. Where T2 represents the second temperature threshold.

[0146] Exemplarily, when T2 ≤ T < T3, the pulse frequency of the ultrasonic transducer can be to turn on for N1 seconds and turn off for N4 seconds, N1 = 1.5N, that is, the target duty cycle is 60%. Where T3 represents the third temperature threshold.

[0147] Exemplarily, when T3 ≤ T < T4, the pulse frequency of the ultrasonic transducer can be to turn on for N1 seconds and turn off for N1 seconds, that is, the target duty cycle is 50%. Where T4 represents the fourth temperature threshold. Optionally, the fourth temperature threshold T4 can be equal to the aforementioned preset temperature threshold.

[0148] It should be noted that the preset temperature range and the corresponding target duty cycle can be set by those skilled in the art according to needs or experience, or determined through a large number of experiments, and this embodiment does not make any limitations thereto.

[0149] S550. Control the ultrasonic transducer to emit ultrasonic waves according to the target power and the target duty cycle to thaw the target object.

[0150] In an optional embodiment, the ultrasonic transducer can be controlled to emit ultrasonic waves according to the target power, the target duty cycle, and the first ultrasonic frequency to thaw the target object. The first ultrasonic frequency can be 20KHZ - 1MHZ.

[0151] In an optional embodiment, the ultrasonic transducer can be controlled to emit ultrasonic waves according to the target power and the target duty cycle; when the temperature of the target object is greater than the first temperature threshold and the temperature of the target object increases after a preset time period, the target power is reduced.

[0152] The preset time period can be set by the technician according to needs or experience, or determined through a large number of experiments, and this embodiment does not make any limitation thereto. Exemplarily, the preset time period can be 1min.

[0153] Optionally, the power weight can be determined according to the preset temperature range corresponding to the target duty cycle; the target power is weighted by the power weight to obtain the reduced target power. Exemplarily, the higher the temperature corresponding to the preset temperature range, the smaller the power weight.

[0154] It can be understood that as the thawing progresses, the temperature of the target object gradually rises. To avoid excessive temperature of the target object, resulting in loss of food nutrition or affecting the taste of the food, the dynamic control of the temperature of the target object can be achieved by adjusting the target duty cycle. At the same time, in another dimension, when reducing the target duty cycle is not sufficient to control the temperature drop of the target object, the target power can be reduced to keep the temperature of the target object dynamically within a certain temperature range.

[0155] For ease of understanding, the following is an exemplary description with the preset time period being 1min and the target power being P, which should not be construed as a limitation on the specific control steps of the ultrasonic transducer.

[0156] Obtain the temperature T of the target object. If T < T1, control the ultrasonic transducer to emit ultrasonic waves according to the target duty cycle of 75% and the target power of P. As the thawing progresses, the temperature of the target object gradually rises. In the case of T1 ≤ T < T2, control the ultrasonic transducer to emit ultrasonic waves according to the target power of P and the target duty cycle of 67%. After 1min, if the temperature of the target object increases, update the target power to: P = (3 / 4)*P.

[0157] Continue to obtain the temperature T of the target object. If T2 ≤ T < T3, control the ultrasonic transducer to emit ultrasonic waves according to the updated target power P and the target duty cycle of 60%. After 1 minute, if the temperature of the target object increases, update the target power to: P = (2 / 3)*P.

[0158] Continue to obtain the temperature T of the target object. If T3 ≤ T < T4, control the ultrasonic transducer to emit ultrasonic waves according to the updated target power P and the target duty cycle of 50%. After 1 minute, if the temperature of the target object increases, update the target power to: P = (1 / 2)*P.

[0159] When the temperature T of the target object is not less than the preset temperature threshold (such as the fourth temperature threshold T4), control the ultrasonic transducer to turn off. When the temperature T of the target object is less than the preset temperature threshold, repeat the above control process again until the termination condition is reached. The termination condition may include at least one of the following: the thawing duration reaches the preset duration; the temperature of the target object reaches the preset temperature threshold.

[0160] S560. When the temperature of the target object is not less than the preset temperature threshold, control the ultrasonic transducer to turn off.

[0161] Among them, the preset temperature threshold can be set by technicians according to needs or experience, or determined through a large number of experiments. This embodiment does not make any limitation on this.

[0162] In some embodiments, a refrigeration device is provided in the refrigerator to adjust the ambient temperature of the storage space. Correspondingly, in response to the thawing control instruction, control the refrigeration device to adjust the ambient temperature to the preset thawing temperature. Among them, the preset thawing temperature can be set by technicians according to needs or experience, or determined through a large number of experiments. This application does not make any limitation on this.

[0163] In the above embodiments, the ultrasonic transducer is introduced to thaw the target object, so that the cavitation effect and mechanical effect generated by the high-frequency vibration of the ultrasonic wave can act on the ice crystals of the target object, accelerate the cracking and melting of the ice layer, which is beneficial to improving the thawing efficiency. At the same time, the ultrasonic energy can penetrate inside and outside the target object to achieve synchronous thawing, reducing local overheating or nutrient loss. By obtaining the target weight and temperature of the target object, a data basis is provided for the dynamic regulation of subsequent thawing control. By introducing the first preset matching relationship and the second preset matching relationship, the target power matching the target weight and the target duty cycle matching the temperature of the target object can be quickly determined. By controlling the ultrasonic transducer to emit ultrasonic waves according to the target power and the target duty cycle to thaw the target object, the problems of local overheating or insufficient thawing are avoided, and the thawing effect is improved.

[0164] In some alternative embodiments, see Figure 6A , provides a refrigerator control method, which is applied to a controller in a refrigerator and may include the following steps:

[0165] S610: Obtain ice-making control instructions.

[0166] The ice making control instruction may be understood as an instruction for freezing ice making raw materials to obtain ice products. The ice making raw materials may include at least one of water and beverages.

[0167] In some embodiments, an ice-making button may be provided on the housing 1 of the refrigerator 100. Accordingly, an ice-making control instruction may be obtained in response to a triggering operation on the ice-making button. The ice-making button may be at least one of a touch button and a mechanical button. This application does not impose any restrictions on the specific installation location and button form of the ice-making button.

[0168] In other embodiments, an ice-making control instruction sent by a mobile terminal or a refrigerator remote control may be obtained.

[0169] In some other embodiments, a timer task may be set to generate an ice-making control instruction when a second timer task is triggered.

[0170] In some embodiments, the ice-making control instruction may include an ultrasonic frequency of an ultrasonic transducer. Exemplarily, the ultrasonic frequency corresponding to the ice-making control instruction may be greater than 1 MHz so that the ultrasonic wave output by the ultrasonic transducer can accelerate the nucleation of supercooled water and shorten the time it takes to convert supercooled water at -5°C to -10°C into ice. At the same time, the ultrasonic wave can guide the ice crystals to be arranged in an orderly manner, forming small and uniform ice crystals, avoiding the problem of a large number of bubbles inside the ice cubes and a loose structure, which is conducive to improving the ice-making effect. It is worth noting that the ultrasonic frequency corresponding to the ice-making control instruction can be set by technicians according to needs or experience, or determined through a large number of experiments, and this application does not impose any restrictions on this.

[0171] S620. In response to the ice-making control instruction, based on a third preset matching relationship, determine a target frequency and a target ambient temperature that match the preset ice-making hardness; wherein an ice-making assembly is provided in the storage space of the refrigerator for storing ice-making raw materials; an ultrasonic transducer is provided in the storage space for emitting ultrasonic waves to the storage space; and a refrigeration device is provided in the refrigerator for adjusting the ambient temperature of the storage space.

[0172] The ice-making assembly can be understood as a container assembly for storing ice-making raw materials.

[0173] With reference to the foregoing, the storage space may be the storage space corresponding to the refrigerating chamber 11 or the freezing chamber 12 , or may be the storage space inside the target container in the refrigerating chamber 11 or the freezing chamber 12 .

[0174] For example, a first container may be provided within the target container, and the ice-making assembly may be detachably mounted within the first container. When thawing is required, the ice-making assembly is removed from the first container, and the target object to be thawed is placed into the first container. When ice making is required, the ice-making assembly is placed into the first container. It should be noted that the ice-making assembly may be mounted within the target container, within the first container, or within the refrigerator compartment 11 or the freezer compartment 12, and this embodiment does not impose any limitations thereto.

[0175] In an optional embodiment, a target container is provided in the box body, and a storage space is formed inside the target container, and the storage space is used to place the ice-making component; a power interface is provided on the target container, and a connecting cable connected to the power interface and the ultrasonic transducer is pre-embedded in the target container.

[0176] refer to Figure 6B FIG2 is a schematic diagram of the structure of the ice making assembly. The target container 51 can be set in the refrigeration drawer a of the refrigeration chamber. The target container 51 is provided with a first container 54, and the first container 54 is provided with at least one ice making assembly 61.

[0177] For example, continue to refer to Figure 5C The bottom of the refrigerated drawer a is provided with a first mounting groove 511 for mounting a target container and a second mounting groove 512 for mounting an ultrasonic transducer 52. A power interface 53 is provided on the refrigerated drawer a. A connecting cable connecting the power interface 53 and the ultrasonic transducer 52 may be pre-embedded in the refrigerated drawer a.

[0178] For example, continue to refer to Figure 5E The target container 51 has a second mounting groove 512 at the bottom thereof for mounting the ultrasonic transducer 52. The target container 51 is provided with a power interface 53. A connecting cable connected to the power interface 53 and the ultrasonic transducer may be pre-buried in the target container 51.

[0179] refer to Figure 6C The figure shows a schematic structural diagram of the first container. The first container 54 may include at least one ice-making assembly 61. The ice-making assembly 61 may include two symmetrically arranged ice-making components 611, with an ice-making space for storing ice-making raw materials formed between the two ice-making components 611, and at least one raw material inlet 612 connected to the ice-making space. It will be understood that after the liquid ice-making raw materials are frozen into a solid ice product, the two ice-making components 611 can be removed to obtain the ice product within the ice-making space. This embodiment does not impose any restrictions on the specific shape and size of the ice-making space. For example, the ice-making space includes at least one spherical space.

[0180] Exemplarily, input slots 613 may be formed at the tops of the two ice-making members 611, and the raw material input port 612 is provided at the bottom of the input slot 613. By providing the input slot, it is convenient to input ice-making raw materials into the ice-making space. Optionally, water level scales may be provided on the side walls of the ice-making tank to facilitate real-time observation of the input amount of the ice-making raw materials.

[0181] Exemplarily, handles 614 may be provided at both ends of the ice-making assembly 61 to facilitate removal from the first container 54. Optionally, a limiting portion 615 may be provided at the position corresponding to the handle 614 in the first container 54 to limit the placement position of the ice-making assembly 61, facilitating quick installation and disassembly.

[0182] Exemplarily, a heat insulation layer 55 may be provided outside the first container 54 to reduce the noise during the operation of the ultrasonic transducer and play a role in heat insulation at the same time.

[0183] Among them, the third preset matching relationship can be understood as a pre-set matching relationship between different preset ice-making hardnesses and corresponding target frequencies and corresponding target ambient temperatures.

[0184] In some embodiments, the third preset matching relationship may be a third relational expression between the preset ice-making hardness, the target frequency, and the target ambient temperature. Correspondingly, the preset ice-making hardness can be input into the third relational expression to obtain the corresponding target frequency and target ambient temperature.

[0185] In other embodiments, the third preset matching relationship may be a third mapping relationship between the preset ice-making hardness, the target frequency, and the target ambient temperature. Correspondingly, the target hardness interval to which the preset ice-making hardness belongs can be determined; based on the third mapping relationship, the target frequency and target ambient temperature matching the target hardness interval are searched for.

[0186] In still other embodiments, the third preset matching relationship may be a matching relationship comparison table between the preset ice-making hardness, the target frequency, and the target ambient temperature. Correspondingly, the target hardness interval to which the preset ice-making hardness belongs can be determined; based on the matching relationship comparison table, the target frequency interval and target ambient temperature interval matching the target hardness interval are searched for; the target frequency is selected from the target frequency interval, and the target ambient temperature is selected from the target ambient temperature interval.

[0187] As shown in Table - 1, it is a matching relationship comparison table. Among them: H1 to H3 respectively represent the first hardness threshold, the second hardness threshold, and the third hardness threshold, and H1 < H2 < H3; F1 to F4 respectively represent the first frequency threshold, the second frequency threshold, the third frequency threshold, and the fourth frequency threshold, and F1 < F2 < F3 < F4; T a1 to T a4represent the first ambient temperature threshold, the second ambient temperature threshold, the third ambient temperature threshold and the fourth ambient temperature threshold respectively, T a1 >T a2 >T a3 >T a4 .

[0188] For example, when the preset ice hardness H belongs to the range of [H1, H2], the target frequency range can be determined as [F1, F2] and the target ambient temperature range can be determined as [T a2 ,T a1 ]. Accordingly, the target frequency F can be selected from [F1, F2], and the target frequency F can be selected from [T a2 ,T a1 ]Select the target ambient temperature T a .

[0189] Table-1 Matching relationship comparison table

[0190] Serial number Preset ice hardness H Target frequency F <![CDATA[Target ambient temperature T a > 1 H<H1 F<F1 <![CDATA[T a >T a1 ]]> 2 H1≤H<H2 F1≤F<F2 <![CDATA[T a2 <T a ≤T a1 ]]> 3 H2≤H<H3 F2≤F<F3 <![CDATA[T a3 <T a ≤T a2 ]]> 4 H>H3 <h2 style=";text-align:left;direction:ltr"><![CDATA[F4>F>F3]]><h2 style=";text-align:left;direction:ltr"> <![CDATA[T a4 <T a ≤T a3 ]]>

[0191] Optionally, when selecting the target frequency F or target ambient temperature T a When the target frequency F is set, the middle value, minimum value or maximum value within the corresponding interval can be selected, or the corresponding value can be randomly selected. This embodiment does not impose any limitation on this. For example, the target frequency F can be greater than 1 MHz.

[0192] S630, controlling the ultrasonic transducer to emit ultrasonic waves according to the target frequency, and controlling the refrigeration equipment to adjust the ambient temperature in the storage space to the target ambient temperature, so that the ice-making raw materials in the ice-making assembly of the storage space are frozen into ice products with a preset ice hardness.

[0193] In an optional embodiment, the refrigeration device may include a compressor 21. For example, a target valve may be provided at the output end of the compressor 21. Accordingly, the opening of the target valve may be adjusted to adjust the ambient temperature in the storage space.

[0194] In the above-described embodiment, by introducing an ultrasonic transducer to freeze the ice-making raw material, ultrasonic waves guide the orderly arrangement of water molecules, facilitating the formation of small and uniform ice crystals and avoiding problems such as excessive bubbles or a loose structure. Furthermore, ultrasonic vibrations can disrupt the supercooled state of the water, accelerating the freezing speed of the ice-making raw material. By introducing a third preset matching relationship and a preset ice hardness, a target frequency and target ambient temperature matching the preset ice hardness can be conveniently and quickly determined, providing a data foundation for subsequent ice-making control. By controlling the ultrasonic transducer to emit ultrasonic waves according to the target frequency and controlling the refrigeration equipment to adjust the ambient temperature within the storage space to the target ambient temperature, the ice-making raw material can be frozen into an ice product having the preset ice hardness.

[0195] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment, in which the ice-making component is refined.

[0196] In some embodiments, an ice-making space for storing ice-making raw materials is provided inside the ice-making assembly; a raw material input port is provided at the top of the ice-making assembly, which is connected to the ice-making space and is used to transport ice-making raw materials to the ice-making space; a cold air channel is provided around the ice-making space inside the ice-making assembly; the air inlet and air outlet of the cold air channel are respectively provided at the bottom of the ice-making assembly; the refrigeration equipment transports cold air into the cold air channel through the air inlet, and discharges it through the air outlet to regulate the temperature of the ice-making space.

[0197] As described above, the ice-making assembly may include two symmetrically arranged ice-making parts, an ice-making space for storing ice-making raw materials is formed between the two ice-making parts, and at least one raw material input port communicated with the ice-making space.

[0198] refer to Figure 7A Figure 1 shows the internal structure of an ice-making assembly in some embodiments. A cold air duct 72 is provided within the ice-making assembly 61, surrounding an ice-making space 71. An air inlet 721 and an air outlet 722 of the cold air duct 72 are located at the bottom of the ice-making assembly 61. The refrigeration equipment delivers cold air into the cold air duct 72 through the air inlet 721 and exhausts it through the air outlet 722, thereby regulating the temperature of the ice-making space 71.

[0199] For example, at least one ice-making space 71 can be provided in the ice-making assembly for each raw material input port 612, and two adjacent ice-making spaces 71 are interconnected. The ice-making space can be at least one of a spherical space and a cubic space, and this embodiment does not impose any limitation on this.

[0200] It can be understood that the air inlet and outlet of the cold air channel are respectively arranged at the bottom of the ice-making assembly, and the raw material input port is arranged at the top of the ice-making assembly, so that the ice-making raw materials can be frozen from bottom to top. During the freezing process from bottom to top, the bubbles in the ice-making raw materials are facilitated to be discharged upward, thereby improving the transparency of the ice-making product.

[0201] In some embodiments, the cold air channel is arranged on both sides of the ice-making space; the cold air channel includes a cold air input channel close to the ice-making space, and a cold air output channel away from the ice-making space; the output end of the cold air input channel is connected to the input end of the cold air output channel; the input end of the cold air input channel corresponds to the air inlet; the output end of the cold air output channel corresponds to the air outlet; after the cold air is input into the cold air input channel through the air inlet, it is discharged through the air outlet of the cold air output channel.

[0202] refer to Figure 7B Schematic diagrams of the internal structure of the ice-making assembly in other embodiments are shown. Cold air is fed into the cold air input channel 723 through the air inlet 721. Since the cold air input channel 723 is located near the ice-making space 71, it facilitates cooling the ice-making space 71. The cold air is then discharged through the air outlet 722 of the cold air output channel 724. Since the cold air output channel 724 is located away from the ice-making space 71, the cold air after heat exchange does not affect the ice-making space 71, thereby improving ice-making efficiency.

[0203] Continue to refer Figure 6C At least one ice-making assembly 61 may be provided in the first container 54 , and a cold air passage 72 may be formed between adjacent ice-making assemblies 61 . The cold air output by the refrigeration device may enter the air inlet at the bottom of the ice-making assembly 61 through the cold air passage 72 .

[0204] It should be further explained that the above refrigerator can realize defrosting control and ice making control.

[0205] When ice making is required, the ice-making assembly can be placed in a target container. In response to an ice-making control instruction, a target frequency and a target ambient temperature matching a preset ice hardness are determined based on a third preset matching relationship. The ultrasonic transducer is controlled to emit ultrasonic waves according to the target frequency, and the refrigeration device is controlled to adjust the ambient temperature within the storage space to the target ambient temperature, so that the ice-making raw materials in the ice-making assembly in the storage space are frozen into ice products of the preset ice hardness.

[0206] When defrosting is required, the ice-making assembly can be taken out of the target container, and the target object can be placed in the target container. In response to the defrosting control instruction, the target weight and target temperature of the target object in the storage space of the target container are obtained; wherein, a temperature sensor, a weighing sensor and an ultrasonic transducer are provided in the storage space; the temperature sensor is used to collect the temperature of the target object; the weighing sensor is used to collect the target weight; the ultrasonic transducer is used to emit ultrasonic waves into the storage space; when the temperature of the target object is less than a preset temperature threshold, based on a first preset matching relationship, a target power matching the target weight is determined; and based on a second preset matching relationship, a target duty cycle matching the temperature of the target object is determined; according to the target power and the target duty cycle, the ultrasonic transducer is controlled to emit ultrasonic waves to defrost the target object; when the temperature of the target object is not less than the preset temperature threshold, the ultrasonic transducer is controlled to be turned off.

[0207] Based on the above embodiment, the refrigerator control method is described in detail. Figure 8 Shown are some other embodiments of refrigerator control methods, including the following steps:

[0208] S801: Obtain a thawing control instruction.

[0209] S802: In response to the thawing control instruction, obtain a target weight and a target temperature of a target object in the storage space of the refrigerator.

[0210] Among them, a temperature sensor, a weighing sensor and an ultrasonic transducer are set in the storage space; the temperature sensor is used to collect the temperature of the target object; the weighing sensor is used to collect the target weight; and the ultrasonic transducer is used to emit ultrasonic waves into the storage space.

[0211] S803 : When the temperature of the target object is lower than a preset temperature threshold, determine the target weight interval to which the target weight belongs from among the preset weight intervals.
