Description

Technical Field

[0001] This application belongs to the field of refrigeration equipment technology, and in particular relates to a refrigeration device and its ice-making control method, ice-making control device, and ice maker. Background Technology

[0002] In the field of ice-making control for refrigeration equipment, it is often difficult to balance ice-making efficiency and energy consumption under different environmental conditions. In existing technologies, the operating logic of ice makers is usually relatively fixed, lacking an intelligent response mechanism to changes in ambient temperature. When the ambient temperature fluctuates significantly, the equipment often cannot accurately maintain the optimal operating temperature of the core ice-making components, easily leading to unstable ice-making speed, inconsistent ice quality, or unnecessary energy consumption under unsuitable operating conditions. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a refrigeration device and its ice-making control method, ice-making control device, and ice maker, which can improve ice-making quality and energy utilization efficiency.

[0004] In a first aspect, this application provides an ice-making control method for a refrigeration device, the refrigeration device including an ice maker, the ice maker including an ice-making container and an ice-making branch, the ice-making branch being connected to the ice-making refrigeration system of the refrigeration device, and at least a portion of the ice-making evaporator of the ice-making branch extending into the ice-making container, the method including: acquiring the current ambient temperature of the refrigeration device; Based on the current ambient temperature, a target compressor speed matching the current ambient temperature is determined through a preset mapping relationship between ambient temperature and compressor speed of the ice-making and refrigeration system. The mapping relationship is configured such that when the ambient temperature is less than 8°C, the compressor speed is a first speed; when the ambient temperature is greater than 8°C and less than 40°C, the compressor speed is increased in stages as the ambient temperature rises; and when the ambient temperature is greater than 40°C, the compressor speed is a second speed, which is greater than the first speed. The compressor is driven to operate at the target compressor speed, so that the temperature of the ice-making evaporator is maintained at... 18℃ to Within a temperature range of 22℃, it outputs cooling capacity at the target ice-making rate.

[0005] According to the ice-making control method of the refrigeration equipment in this application, by establishing a mapping relationship between ambient temperature and compressor speed, the ice-making process of the refrigeration equipment is dynamically optimized, so that the ice-making evaporator can be maintained in the working temperature range of -18℃ to -22℃, avoiding the instability of ice-making efficiency caused by ambient temperature fluctuations. While ensuring the target ice-making speed, the ineffective energy consumption of the refrigeration equipment is significantly reduced through segmented speed control, thereby improving the ice-making quality and energy utilization efficiency.

[0006] According to one embodiment of this application, determining a target compressor speed that matches the current ambient temperature based on a preset mapping relationship between the ambient temperature and the compressor speed of the ice-making refrigeration system includes: Based on the current ambient temperature and the current ice-making water temperature of the ice-making container, the target compressor speed is determined by querying a preset compressor speed control table. The compressor speed control table is used to determine the compressor speed corresponding to different combinations of ambient temperature and ice-making water temperature.

[0007] According to one embodiment of this application, the target ice-making speed is determined through the following steps: Based on the current ice-making water temperature of the ice-making container, the predicted ice-making time under the current working conditions is predicted through a preset ice-making time prediction model. The ice-making time prediction model is a cubic surface polynomial model that characterizes the relationship between the temperature of the ice-making evaporator, the ice-making water temperature, the preset ice block thickness and the ice-making time. Based on the predicted ice-making time, the target ice-making speed is determined.

[0008] According to one embodiment of this application, the compressor is driven to operate at the target compressor speed, thereby maintaining the temperature of the ice-making evaporator at [temperature value missing]. 18℃ to Within a temperature range of 22°C, and with a target ice-making rate, the cooling output includes: Based on the current temperature of the ice-making evaporator, the current heat flux density is calculated using a preset quadratic polynomial heat flux density model. The expression of the heat flux density model is q = 51.8774T² + 1670.7T + 22824, where q is the heat flux density and T is the temperature of the ice-making evaporator. If the current heat flux density deviates from the preset heat flux density threshold, the operating speed of the compressor is adjusted based on the target compressor speed to stabilize the temperature within the range of -18°C to -22°C, wherein the preset heat flux density threshold is determined based on the target ice-making speed and the current ice-making water temperature of the ice-making container.

[0009] According to one embodiment of this application, the ice-making control method of the refrigeration equipment further includes: When the time for switching the ice-making branch to the ice-making path reaches the first ice-making time, the heating element of the ice-making branch is turned on. When the time for switching the ice-making branch to the ice-making path reaches the second ice-making time, the de-icing timer is activated, the ice-making container is controlled to the de-icing position, the first temperature of the ice-making evaporator is obtained, and the ice-making branch is controlled to switch to the de-icing path. When the time for switching from the ice-making branch to the de-icing path reaches the first de-icing time, the second temperature of the ice-making evaporator is obtained; If the first temperature and the second temperature meet the preset temperature conditions, it is determined that the ice-making function of the ice maker is normal.

[0010] According to one embodiment of this application, after determining that the ice-making function of the ice maker is normal, the method further includes: When the time for switching from the ice-making branch to the de-icing path reaches the third de-icing time, the heating element is turned off.

[0011] Secondly, this application provides an ice-making control device for a refrigeration system. The refrigeration system includes an ice maker, which includes an ice-making container and an ice-making branch. The ice-making branch is connected to the ice-making refrigeration system of the refrigeration system, and at least a portion of the ice-making evaporator of the ice-making branch extends into the ice-making container. The ice-making control device includes: A temperature sensor, used to acquire the current ambient temperature of the refrigeration equipment; A controller, connected to the temperature sensor, is configured to perform the following steps: Based on the current ambient temperature, a target compressor speed matching the current ambient temperature is determined through a preset mapping relationship between ambient temperature and compressor speed of the ice-making and refrigeration system. The mapping relationship is configured such that when the ambient temperature is less than 8°C, the compressor speed is a first speed; when the ambient temperature is greater than 8°C and less than 40°C, the compressor speed is increased in stages as the ambient temperature rises; and when the ambient temperature is greater than 40°C, the compressor speed is a second speed, which is greater than the first speed. The compressor is driven to operate at the target compressor speed, so that the temperature of the ice-making evaporator is maintained at... 18℃ to Within a temperature range of 22℃, it outputs cooling capacity at the target ice-making rate.

[0012] According to the ice-making control device of the refrigeration equipment of this application, by establishing a mapping relationship between ambient temperature and compressor speed, the ice-making process of the refrigeration equipment is dynamically optimized, so that the ice-making evaporator can be maintained in the working temperature range of -18℃ to -22℃, avoiding the instability of ice-making efficiency caused by ambient temperature fluctuations. While ensuring the target ice-making speed, the segmented speed control significantly reduces the ineffective energy consumption of the refrigeration equipment, thereby improving the ice-making quality and energy utilization efficiency.

[0014] According to the ice maker of this application, by establishing a mapping relationship between ambient temperature and compressor speed, the dynamic optimization of the ice-making process of the refrigeration equipment is realized, so that the ice evaporator can be maintained in the working temperature range of -18℃ to -22℃, avoiding the instability of ice-making efficiency caused by ambient temperature fluctuations. While ensuring the target ice-making speed, the segmented speed control significantly reduces the ineffective energy consumption of the refrigeration equipment, thereby improving the ice-making quality and energy utilization efficiency.

[0016] According to the refrigeration equipment of this application, by establishing a mapping relationship between ambient temperature and compressor speed, the dynamic optimization of the ice-making process of the refrigeration equipment is realized, so that the ice-making evaporator can be maintained in the working temperature range of -18℃ to -22℃, avoiding the instability of ice-making efficiency caused by ambient temperature fluctuations. While ensuring the target ice-making speed, the ineffective energy consumption of the refrigeration equipment is significantly reduced through segmented speed control, thereby improving the ice-making quality and energy utilization efficiency.

[0023] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The ice-making control method, ice-making control device, ice maker 500, refrigeration equipment, and electronic equipment of the present application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0026] The ice-making control method of the refrigeration equipment can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0027] It should be noted that the refrigeration equipment in this embodiment includes, but is not limited to, refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines, etc. The refrigeration equipment has a variety of structural forms and a wide range of applications.

[0028] The following is for reference. Figures 3-5 This application describes a refrigeration device according to an embodiment of the present application.

[0029] In some embodiments, the refrigeration device includes: a housing, an ice-making refrigeration system 800, and an ice maker 500. The housing forms a compartment; the ice-making refrigeration system 800 is installed in the housing; the ice maker 500 is installed in the compartment, and the ice maker 500 includes an ice-making container 520 and an ice-making branch 580. The ice-making branch 580 is connected to the ice-making refrigeration system 800, and the ice-making branch 580 includes an ice-making throttling section 582 and an ice-making evaporator 581 connected in sequence. The ice-making evaporator 581 conducts heat with the ice-making container 520 or conducts heat with the liquid inside the ice-making container 520.

[0030] The refrigeration equipment enclosure may include a cabinet and a door. The door is installed on the open side of the cabinet, thereby sealing the cabinet to form a closed compartment for storage. The cabinet may include an outer shell, an inner liner, and an insulation layer. The inner liner may be located inside the outer shell, and the insulation layer may be formed between the outer shell and the inner liner through a foaming process. The compartment may include, but is not limited to, a refrigeration compartment, a freezer compartment, or a variable temperature compartment, etc., and the embodiments of this application do not impose such limitations.

[0031] The ice-making and refrigeration system 800 can have at least one of the following structural forms: Firstly, the ice-making and refrigeration system 800 can be used to cool a room. The cooling method can include, but is not limited to, direct cooling, air cooling, or a combination of both. This application embodiment does not limit this.

[0032] like Figure 5 As shown, the ice-making and refrigeration system 800 may include a compressor 810, a condenser 820, a refrigeration throttling section 832, and a refrigeration evaporator 831. The compressor 810, condenser 820, refrigeration throttling section 832, and refrigeration evaporator 831 are connected sequentially to form a complete refrigeration cycle. The refrigeration throttling section 832 can throttle and reduce the pressure of the high-pressure liquid refrigerant flowing out of the condenser 820 outlet, turning it into a low-pressure liquid refrigerant, which then flows into the refrigeration evaporator 831 to evaporate and absorb heat, thereby providing cooling capacity to the corresponding room.

[0033] like Figure 5 As shown, the ice-making refrigeration system 800 may also include a filter device 840. The filter device 840 may be located between the inlet of the refrigeration throttling section 832 and the outlet of the condenser 820. The filter device 840 is used to filter impurities from the refrigerant and lubricating oil that have not yet entered the refrigeration throttling section 832 and the ice-making throttling section 582, so as to prevent the refrigeration throttling section 832 and the ice-making throttling section 582 with small diameter from becoming blocked, and to maintain the smooth flow of the pipeline system.

[0034] Secondly, the ice-making and refrigeration system 800 can be an independent ice-making and refrigeration system 800.

[0035] In this embodiment, the ice-making and refrigeration system 800 operates independently from the original compartment refrigeration system 800 of the refrigeration equipment and does not interfere with each other. The ice-making and refrigeration system 800 may include a compressor 810 and a condenser 820. The compressor 810, the condenser 820 and the ice-making branch 580 are connected end to end to form a complete ice-making and refrigeration cycle.

[0036] The ice maker 500 can be installed as an independent ice-making module that can generate and store ice inside the refrigeration equipment room.

[0037] The ice maker 500 of this application is installed inside the refrigerator compartment of a refrigeration system. The ice maker 500 can be installed on the inner liner of the refrigerator compartment; or, the ice maker 500 can also be installed on the door of the refrigerator compartment.

[0038] In some embodiments, at least a portion of the ice-making evaporator 581 extends into the ice-making container 520 to allow heat conduction between the ice-making evaporator 581 and the liquid within the ice-making container 520. This portion of the ice-making evaporator 581 extending into the ice-making container 520 can directly contact the water within the ice-making container 520, causing the water surrounding this portion of the ice-making evaporator 581 to freeze upon cooling, forming an ice block surrounding this portion of the ice-making evaporator 581. Because this portion of the ice-making evaporator 581 is located in the central region of the ice block structure, the resulting ice block is a hollow structure with a central groove.

[0039] The specific shape of the ice block may include, but is not limited to, hollow cylinder, hollow cube, hollow prism, hollow sphere, or hollow hemisphere, etc., and the embodiments of this application do not limit this.

[0040] The ice maker 500 may also include structures such as an ice storage container 530, a water tank 540, electrical components 561, and a water circuit assembly 562. The water tank 540 can supply water to the ice-making container 520 through the water circuit assembly 562. The water in the ice-making container 520 that has not frozen into ice can be circulated back to the water tank 540 by the drive of the electrical components 561. In other words, a water circuit is formed between the water tank 540 and the ice-making container 520. A part of the ice-making evaporator 581 can be buried below the liquid surface in the ice-making container 520. The refrigerant flowing through it evaporates and absorbs heat, causing the surface temperature of the ice-making evaporator 581 to drop sharply. This causes the water immersed around the ice-making evaporator 581 to freeze rapidly and eventually condense and adhere to the ice-making evaporator 581 to form ice. Ice blocks adhering to the ice evaporator 581 can be peeled off by the flowing hot refrigerant and fall into the ice storage container 530. Users can open the compartment at any time to retrieve the ice blocks stored in the ice storage container 530 of the ice maker 500.

[0041] In other embodiments, the ice-making evaporator 581 is located outside the ice-making container 520, in which case the ice-making evaporator 581 is isolated from the liquid inside the ice-making container 520. The ice-making evaporator 581 can directly contact the ice-making container 520, or it can indirectly contact the ice-making container 520 through a heat-conducting layer. The ice-making evaporator 581 transfers cold energy to the ice-making container 520, which in turn transfers the cold energy to the water inside. The water freezes into ice blocks inside the ice-making container 520, which acts as a mold. The shape of the ice blocks depends on the shape of the internal cavity of the ice-making container 520.

[0042] The specific shape of the ice block may include, but is not limited to, a solid cube, a solid sphere, a solid cylinder, or a solid hemisphere, etc., and this application embodiment does not limit this.

[0043] like Figure 5 As shown, the ice-making and refrigeration system 800 also includes a valve assembly 850, which is used to control the on / off connection between the condenser 820 and the ice-making throttling section 582.

[0044] like Figure 3 As shown, Figure 3 This is a sectional perspective view of the ice maker 500 taken at an angle to the cross-section. A water circulation path is formed between the ice container 520 and the water tank 540, and the ice container 520 is rotatable relative to the ice evaporator 581. At least a portion of the ice evaporator 581 is adapted to extend into the ice container 520.

[0045] like Figure 3 and Figure 4 As shown, the ice-making evaporator 581 includes a distribution component 5811 and a plurality of ice-making columns 5812 connected to the distribution component 5811. The distribution component 5811 is connected to the ice-making refrigeration system 800. The plurality of ice-making columns 5812 are vertically opposite to the ice storage container 530. The rotatably mounted ice-making container 520 can selectively separate the ice storage container 530 and the plurality of ice-making columns 5812. Figure 3 As shown, in the ice-making state, at least a portion of the multiple ice-making columns 5812 extend into the ice-making container 520 to generate ice. In the de-icing state, the ice-making container 520 rotates to be offset from the multiple ice-making columns 5812, that is, rotates to the side of the multiple ice-making columns 5812, so that there is no longer an ice-making container 520 obstructing the ice storage container 530 and the multiple ice-making columns 5812, so that the ice generated on the ice-making columns 5812 can fall into the ice storage container 530 under the action of gravity.

[0046] The distribution component 5811 is used to distribute the refrigerant of the future homemade ice refrigeration system 800 to multiple ice-making columns 5812. The distribution component 5811 can be, but is not limited to, a distribution plate or a distribution pipe, etc. The embodiments of this application do not limit this.

[0047] It should be noted that, as Figure 3 and Figure 4 As shown, the ice-making column 5812 is designed in a cylindrical shape, and multiple ice-making columns 5812 can simultaneously form multiple ice blocks.

[0048] In this context, "multiple" means two or more, and the specific number of ice columns 5812 depends on actual needs; this application embodiment does not impose any restrictions on this.

[0049] In some embodiments, such as Figure 4As shown, the ice container 520 has an overflow port 521 on at least one side adjacent to the opening.

[0050] In some embodiments, such as Figure 3 and Figure 4 As shown, the ice maker 500 also includes a housing 510.

[0051] Ice evaporator 581, ice container 520 and water tank 540 are mounted on housing 510.

[0052] In this embodiment, such as Figure 3 and Figure 4 As shown, the housing 510 serves as the supporting structure and external enclosure frame of the ice maker 500. The interior of the housing 510 can form an installation space for accommodating the ice evaporator 581, ice container 520, ice storage container 530, water tank 540, electrical components 561, and water circuit components 562, so that the ice maker 500 can be assembled and maintained as a complete module.

[0053] At least a portion of the water tank 540 can be installed within the receiving space formed by the housing 510, and at least a portion of the ice storage container 530 can be installed within the receiving space formed by the housing 510. For example, as... Figure 3 and Figure 4 As shown, the water tank 540 can be pulled out and installed on the housing 510, and the ice storage container 530 can be supported on the water tank 540, so that the water tank 540 and the ice storage container 530 can be pulled out synchronously.

[0054] This application provides another structure for an ice maker 500.

[0055] The housing 510 serves as the supporting structure and external enclosure frame of the ice maker 500. The interior of the housing 510 can form an installation space for accommodating the ice evaporator 581, ice container 520, ice storage container 530, water tank 540, electrical components 561, and water circuit components 562, so that the ice maker 500 can be assembled and maintained as a complete module.

[0056] The ice storage container 530 can be pulled out and installed on the housing 510 along the front and rear direction of the refrigeration equipment via a guide rail structure, and is used to receive ice blocks that fall off the ice evaporator 581.

[0057] The ice storage container 530 is lower than the ice evaporator 581 in the height direction. The ice storage container 530 can be located directly below the ice evaporator 581, or it can be at least partially offset from the ice evaporator 581. The specific relative position relationship shall be based on not affecting the normal ice storage function, and this application embodiment does not limit it.

[0058] The water tank 540 can be pulled out and installed on the housing 510 along the front and rear direction of the refrigeration equipment via a guide rail structure, and is used to store water for ice making.

[0059] The water tank 540 is lower than the ice storage container 530 in the height direction. The water tank 540 can be located directly below the ice storage container 530, or it can be at least partially offset from the ice storage container 530. The specific relative position relationship shall be based on not affecting the normal discharge of ice melt water and the water circulation function. This application embodiment does not limit this.

[0060] As an example, the ice maker 500 may also include structures such as electrical components 561 and water circuit components 562. The water tank 540 can supply water to the ice container 520 through the water circuit components 562. The water in the ice container 520 that has not frozen into ice can be flipped back to the water tank 540 under the drive of the electrical components 561, thereby realizing water circulation between the ice container 520 and the water tank 540.

[0061] The portion of the ice-making evaporator 581 that extends into the ice-making container 520 can directly contact the water in the ice-making container 520, causing the water surrounding the portion of the ice-making evaporator 581 to freeze after being cooled, so as to form an ice block that is fitted outside the portion of the ice-making evaporator 581. Since the portion of the ice-making evaporator 581 is located in the central area of ​​the ice block structure, the produced ice block is a hollow structure with a central groove.

[0062] The specific shape of the ice block may include, but is not limited to, hollow cylinder, hollow cube, hollow prism, hollow sphere, or hollow hemisphere, etc., and the embodiments of this application do not limit this.

[0063] The ice-making evaporator 581 includes a distribution member 5811 and a plurality of ice-making columns 5812 connected to the distribution member 5811. The distribution member 5811 is connected to the ice-making refrigeration system 800. The plurality of ice-making columns 5812 constitute the ice-making part of the ice-making evaporator 581. In other words, the plurality of ice-making columns 5812 and the ice storage chamber of the ice storage container 530 are vertically opposite each other, and the plurality of ice-making columns 5812 and the water passage chamber of the ice storage container 530 are offset. The rotatably mounted ice-making container 520 can selectively separate the ice storage container 530 and the plurality of ice-making columns 5812. In the ice-making state, at least a portion of the plurality of ice-making columns 5812 extends into the ice-making container 520 to generate ice. In the de-icing state, the ice-making container 520 rotates to be offset from the multiple ice-making columns 5812, that is, rotates to the side of the multiple ice-making columns 5812, so that there is no longer an ice-making container 520 obstructing the ice storage cavity of the ice storage container 530 and the multiple ice-making columns 5812, so that the ice generated on the ice-making columns 5812 can fall into the ice storage cavity of the ice storage container 530 under the action of gravity.

[0064] The distribution component 5811 is used to distribute the refrigerant of the future homemade ice refrigeration system 800 to multiple ice-making columns 5812. The distribution component 5811 can be, but is not limited to, a distribution plate or a distribution pipe, etc. The embodiments of this application do not limit this.

[0065] It should be noted that, based on the design of the ice-making column 5812 as a cylinder, multiple ice-making columns 5812 can simultaneously form multiple ice blocks, so that the ice blocks formed on multiple ice-making columns 5812 are hollow cylindrical.

[0066] In this context, "multiple" refers to two or more ice-making columns 5812. The specific number depends on actual needs, and this application embodiment does not impose any limitations on this. The following is a general description of the ice-making electronic control process.

[0067] After the system is powered on, it first performs a self-test and reads sensor data such as water level, temperature, and ice full signal. If the water level is normal and no ice fullness is detected, water is added to the set level and then shut off, and the refrigeration cycle is started. During the ice-making process, the temperature of the ice evaporator 581 is monitored in real time, or the cumulative running time is recorded. When the preset threshold for ice completion is reached, the system enters the de-icing mode. The heating wire is heated to cause the ice layer to fall off and trigger the ice-falling switch to confirm that the ice block falls into the ice storage container 530. Then, the ice fullness is checked again. If it is not full, the system automatically enters the next water-filling-ice-de-icing cycle. If ice fullness is detected or there are abnormalities such as water shortage, overheating, or communication failure, the system immediately stops and displays the corresponding fault code to protect the equipment.

[0068] In actual operation, the ice-making function can be achieved as follows: When the ice maker 500 is in the ice-making state, the opening of the ice container 520 faces upward, and a portion of each ice column 5812 of the ice evaporator 581 can be buried below the liquid surface in the ice container 520. Through the evaporation and heat absorption of the flowing refrigerant, the temperature of the surface of the ice evaporator 581 drops sharply, thereby causing the water soaked around each ice column 5812 to freeze quickly and eventually condense and adhere to each ice column 5812 to form ice blocks. During this period, the water tank 540 continuously supplies water to the ice-making container 520 through the water circuit assembly 562. When the water level rises to exceed the maximum capacity of the ice-making container 520, the excess water will overflow from the open side of the ice-making container 520 and fall into the water tank 540 under the action of gravity. In other words, the water tank 540 continuously supplies water to the ice-making container 520 throughout the entire ice-making process, and will not stop supplying water when the ice-making container 520 reaches the maximum water level, so that the water in the ice-making container 520 is always circulating. This circulating water can reduce the generation of air bubbles in the ice.

[0069] The de-icing function is achieved as follows: Electrical component 561 drives the ice-making container 520 to rotate. During rotation, the controller of the refrigeration equipment precisely controls the rotational speed of the tilting shaft of the ice-making container 520 to maintain smooth rotation as much as possible. By driving the ice-making container 520 to tilt, the unfrozen water inside the ice-making container 520 is returned to the water tank 540. When the ice maker 500 is in the de-icing state, the opening of the ice-making container 520 faces to the side, and the ice-making container 520 does not obstruct the space below the multiple ice columns 5812. After the ice evaporator 581 is heated, the ice layer adhering between the ice and the corresponding ice column 5812 melts into a water film, greatly reducing the adhesion. Thus, the ice originally attached to the ice column 5812 can be peeled off by its own gravity and fall into the ice storage container 530 below. The user can open the compartment at any time to take out the ice stored in the ice storage container 530.

[0070] The ice-making control method for a refrigeration device provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the ice-making control method for the refrigeration device. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras, and wearable devices. The ice-making control method for a refrigeration device provided in this application embodiment is described below using an electronic device as the execution subject.

[0071] The refrigeration equipment includes an ice maker 500, which includes an ice-making container 520 and an ice-making branch 580. The ice-making branch 580 is connected to the ice-making refrigeration system 800 of the refrigeration equipment, and at least a portion of the ice-making evaporator 581 of the ice-making branch 580 extends into the ice-making container 520.

[0072] like Figure 1 As shown, the ice-making control method of the refrigeration equipment includes steps S1 and S2.

[0073] Step S1: Obtain the current ambient temperature of the refrigeration equipment.

[0074] The current ambient temperature refers to the temperature of the air surrounding the refrigeration equipment. It can be measured directly by the temperature sensor built into the refrigeration equipment or indirectly obtained by accessing local meteorological data via the network.

[0075] Step S2: Based on the current ambient temperature, the target compressor 810 speed matching the current ambient temperature is determined through a preset mapping relationship between the ambient temperature and the compressor 810 speed of the ice-making and refrigeration system 800. The mapping relationship is configured such that when the ambient temperature is less than 8°C, the compressor 810 speed is the first speed; when the ambient temperature is greater than 8°C and less than 40°C, the compressor 810 speed is increased in stages as the ambient temperature rises; when the ambient temperature is greater than 40°C, the compressor 810 speed is the second speed, which is greater than the first speed.

[0076] The target compressor speed is the speed at which the compressor 810 is expected to reach.

[0077] In this embodiment, based on the mapping relationship between ambient temperature and compressor 810 speed, the monitored current ambient temperature is converted into a specific compressor 810 operating command to determine the target compressor 810 speed that best matches the current operating conditions.

[0078] When the ambient temperature is below 8℃ and the environment is cold, the heat dissipation efficiency is high, and the system locks a low first speed to prevent the compressor 810 from overcooling or frequently starting and stopping, thus achieving energy-saving operation.

[0079] When the ambient temperature is greater than 8℃ and less than 40℃, the medium temperature dynamic adjustment is used. The speed is positively correlated with the ambient temperature. As the room temperature rises, the speed of the compressor 810 is gradually increased in stages to linearly offset the interference of ambient heat on the cooling effect and maintain temperature stability.

[0080] When the ambient temperature is above 40℃, the environment is extremely hot. The system is forced to switch to the highest second speed to ensure that the evaporator can still maintain a low temperature of -18℃ to -22℃ under the condition of difficult heat dissipation, so as to ensure that ice making is uninterrupted.

[0081] Step S3: Drive compressor 810 to run at the target compressor speed, so that the temperature of ice-making evaporator 581 is maintained at... 18℃ to Within a temperature range of 22℃, it outputs cooling capacity at the target ice-making rate.

[0082] The target ice-making rate is the ideal ice production rate or cooling output rate per unit time under the condition of maintaining the evaporator temperature between -18°C and -22°C.

[0083] In this embodiment, the compressor 810 is driven to run at the target compressor speed, so that the heat absorption capacity of the ice evaporator 581 is dynamically balanced with the current ambient heat load. The temperature of the ice evaporator 581 is strictly locked between -18°C and -22°C to prevent the temperature from being too high, which would cause slow freezing or soft ice, and also to avoid the temperature being too low, which would cause energy waste or overload of the equipment. This ensures that the machine can continuously and stably output cold energy at the target ice-making speed, and achieve the best balance between ice-making efficiency and ice quality.

[0084] According to the ice-making control method of the refrigeration equipment provided in the embodiments of this application, by establishing a mapping relationship between ambient temperature and compressor speed 810, the dynamic optimization of the ice-making process of the refrigeration equipment is realized, so that the ice-making evaporator 581 can be maintained in the working temperature range of -18℃ to -22℃, avoiding the instability of ice-making efficiency caused by ambient temperature fluctuations. While ensuring the target ice-making speed, the ineffective energy consumption of the refrigeration equipment is significantly reduced through segmented speed control, thereby improving the ice-making quality and energy utilization efficiency.

[0085] In some embodiments, based on the current ambient temperature, a target compressor 810 speed matching the current ambient temperature is determined through a preset mapping relationship between the ambient temperature and the compressor 810 speed of the ice-making and refrigeration system 800, including: Based on the current ambient temperature and the current ice-making water temperature of the ice-making container 520, the target compressor 810 speed is determined by querying the preset compressor 810 speed control table. The compressor 810 speed control table is used to determine the compressor 810 speed corresponding to different combinations of ambient temperature and ice-making water temperature.

[0086] The current ice-making water temperature is the temperature value of the water to be frozen in the ice-making container 520 under real-time monitoring.

[0087] In this embodiment, two key indicators are collected simultaneously: the external heat dissipation conditions, i.e., the current ambient temperature, and the internal freezing state, i.e., the current ice-making water temperature. By querying the preset compressor 810 speed control table, the most suitable target compressor 810 speed under the specific combination of the current ambient temperature and the current ice-making water temperature is directly matched, thereby ensuring that no matter how the external temperature changes, no matter whether the water has just started to freeze or is close to freezing, the compressor 810 can output the most matched cooling capacity, achieving a precise balance between ice-making efficiency and quality.

[0088] In some embodiments, the target ice-making rate is determined by the following steps: Based on the current ice-making water temperature of the ice-making container 520, the predicted ice-making time under the current working condition is predicted through a preset ice-making time prediction model. The ice-making time prediction model is a cubic surface polynomial model that characterizes the relationship between the temperature of the ice-making evaporator 581, the ice-making water temperature, the preset ice thickness and the ice-making time. The target ice-making speed is determined based on the predicted ice-making time.

[0089] The preset ice thickness is the target size or thickness value of the ice block that is pre-set by the user or the system and serves as the criterion for determining whether ice making is complete.

[0090] In this embodiment, a cubic surface polynomial is used to construct an ice-making time prediction model to capture the complex nonlinear heat exchange law during the ice-making process. The mechanism takes the temperature of the ice-making evaporator 581 (cold source capacity), the current ice-making water temperature (heat load state), and the preset ice block thickness (target workload) as key variables input into the model. Through the coupling calculation of multi-dimensional parameters, the predicted ice-making time required to complete ice-making under the current specific working conditions is accurately deduced.

[0091] Using the calculated predicted ice-making time as a benchmark, and through the reciprocal relationship of time, the target ice-making speed required to complete the ice-making task within the predicted ice-making time is derived.

[0092] In some embodiments, the compressor 810 is driven to operate at the target compressor 810 speed, so that the temperature of the ice-making evaporator 581 is maintained at... 18℃ to Within a temperature range of 22°C, and with a target ice-making rate, the cooling output includes: Based on the current temperature of the ice evaporator 581, the current heat flux density is calculated using a preset quadratic polynomial heat flux density model. The expression for the heat flux density model is q = 51.8774T² + 1670.7T + 22824, where q is the heat flux density and T is the temperature of the ice evaporator 581. If the current heat flux density deviates from the preset heat flux density threshold, the operating speed of the compressor 810 is adjusted based on the target compressor 810 speed to maintain the temperature stably within the range of -18℃ to -22℃. The preset heat flux density threshold is determined based on the target ice-making speed and the current ice-making water temperature of the ice-making container 520.

[0093] The current heat flux density is a physical quantity that characterizes the amount of heat transferred per unit time per unit area at the current moment.

[0094] The preset heat flux density threshold is determined by calculating the heat exchange power required to freeze water at the current ice-making temperature into ice at the target ice-making rate.

[0095] In this embodiment, the current heat flux density (q) is accurately calculated based on the current temperature (T) of the ice evaporator 581 using a preset quadratic polynomial heat flux density model q=51.8774T2+1670.7T+22824. Subsequently, the calculated value is compared with the heat flux density threshold dynamically generated based on the target ice-making speed and the current water temperature. If a deviation is detected, a fine adjustment is made based on the target compressor speed 810 to ensure that the temperature of the ice evaporator 581 is within the optimal temperature range of -18℃ to -22℃, thereby achieving precise matching and stable control of the cooling output.

[0096] In some embodiments, the ice-making control method of the refrigeration equipment further includes: When the ice-making branch 580 switches to the ice-making path for the duration of the first ice-making time, the heating element of the ice-making branch 580 is turned on.

[0097] Among them, the ice-making passage is the refrigerant flowing through the ice-making branch 580 to the ice-making evaporator 581 to achieve the working state of refrigeration and icing or the pipeline configuration.

[0098] The first ice-making time is the time threshold set after the ice-making branch 580 switches to the ice-making path to achieve freezing. It can be set according to water temperature, ambient temperature, and equipment performance.

[0099] The heating element is an electric heating device in the ice maker 500 used to apply heat to the ice evaporator 581 or ice during the de-icing stage to facilitate the smooth detachment of the ice.

[0100] In this step, after the ice-making branch 580 switches to the ice-making path, the ice-making refrigeration system 800 begins to supply cooling to the ice-making evaporator 581, causing the water in the ice-making container 520 to gradually freeze into ice. After the first ice-making time, it is determined that the ice has reached a state where it can be removed. At this time, the heating element in the ice-making branch 580 is turned on to briefly and controllably heat the ice-making evaporator 581 or the bottom of the ice block, so as to weaken the adhesion between the ice and the surface of the ice-making evaporator 581 before the ice is officially removed, thus preparing for the subsequent smooth removal of ice.

[0101] In this embodiment, when the ice-making branch 580 switches to the ice-making path for a period of time equal to the second ice-making duration, the de-icing timer is activated, the ice-making container 520 is controlled to the de-icing position, the first temperature of the ice-making evaporator 581 is obtained, and the ice-making branch 580 is controlled to switch to the de-icing path.

[0102] The second ice-making time is the threshold time required for water to be completely frozen into removable ice blocks when the ice-making branch 580 is in the ice-making passage state.

[0103] The de-icing timer is an operation used to record the duration of the de-icing process, starting from the transition from the completion of ice making to the de-icing stage.

[0104] The de-icing position is as follows Figure 4 As shown, the ice-making container 520 is rotated to be offset from the multiple ice-making columns 5812, that is, rotated to the side of the multiple ice-making columns 5812, so that there is no longer an ice-making container 520 between the ice storage container 530 and the multiple ice-making columns 5812, so that the ice generated on the ice-making columns 5812 can fall into the ice storage container 530 under the action of gravity.

[0105] The first temperature is the temperature of the ice-making evaporator 581 collected at the moment ice making is completed and the circuit switches to the de-icing path.

[0106] The de-icing pathway is the pipeline state switched in the ice-making branch 580 to achieve de-icing. It can stop refrigeration or introduce heating to raise the temperature of the ice-making evaporator 581 to loosen and detach the ice.

[0107] In this step, when the ice-making branch 580 has been running continuously for a preset second ice-making time since switching to the ice-making path, the ice-making stage is determined to be completed, and the de-icing timer is started to accurately record the duration of the subsequent de-icing process. At the same time, the ice-making container 520 is moved or flipped to the de-icing position to prepare mechanically for the ice to detach. At this switching node, the temperature of the ice-making evaporator 581 is collected as the first temperature, and then the ice-making branch 580 is switched from the ice-making path to the de-icing path, causing the temperature of the ice-making evaporator 581 to rise, thereby weakening the adhesion between the ice and the surface of the ice-making evaporator 581, creating conditions for the ice to detach smoothly.

[0108] In this embodiment, when the ice-making branch 580 switches to the de-icing path for a period of time equal to the first de-icing time, the second temperature of the ice-making evaporator 581 is obtained.

[0109] The first de-icing time is the heating or temperature rise duration set after the ice-making branch 580 switches to the de-icing path, in order to allow the ice to be fully heated and loosened and to complete the de-icing process.

[0110] The second temperature is the temperature of the ice-making evaporator 581 measured when the de-icing passage has been running for the first de-icing time.

[0111] In this embodiment, if the first temperature and the second temperature meet the preset temperature conditions, it is determined that the ice-making function of the ice maker 500 is normal.

[0112] The preset temperature condition is a pre-set temperature criterion used to determine whether the ice-removing process of the ice maker 500 is effective, such as the second temperature being higher than the first temperature by a certain margin, or reaching a specific threshold.

[0113] In this embodiment, when parameters such as the difference between the first temperature and the second temperature, and the heating rate of the second temperature relative to the first temperature meet the preset temperature conditions, it indicates that the heat provided during the de-icing stage is sufficient to generate a micro-melting layer between the ice and the surface of the ice-making evaporator 581, reducing the adhesion force and thus achieving smooth de-icing. In addition, if the ice is not fully frozen, or the de-icing heating is insufficient or too rapid, the temperature rise amplitude or rate will deviate from the preset temperature conditions. When the first temperature and the second temperature meet the preset temperature conditions, it can be determined that the ice-making function of the ice maker 500 is normal. The ice-making function includes the functions corresponding to the ice-making process and the functions corresponding to the de-icing process.

[0114] In some embodiments, the preset temperature condition includes a second temperature and a first temperature that are greater than a preset temperature threshold.

[0115] The preset temperature threshold is a pre-set minimum temperature rise value, used to determine whether the ice-making evaporator 581 has received sufficient effective heating to allow the ice to detach smoothly during the de-icing process.

[0116] In this embodiment, the difference between the second temperature and the first temperature is greater than a preset temperature threshold to ensure that the ice evaporator 581 obtains sufficient heat during the de-icing stage, so as to effectively weaken the adhesion between the ice and the surface of the ice evaporator 581, thereby verifying that the heating function is normal and the de-icing process can be completed smoothly.

[0117] In some embodiments, after obtaining the second temperature of the ice-making evaporator 581, the method further includes: If the first and second temperatures do not meet the preset temperature conditions, perform the de-icing recovery operation.

[0118] The de-icing recovery operation includes turning off the heating element and cutting off the ice-making branch 580, then turning the heating element back on and controlling the ice-making branch 580 to switch to the de-icing path again.

[0119] In this embodiment, if the first temperature and the second temperature do not meet the preset temperature conditions, it indicates that the heating during the de-icing process has not achieved the expected effect. The heating element is first turned off and the ice-making branch 580 is cut off to terminate the abnormal state. Then the heating element is turned on again and the ice-making branch 580 is switched back to the de-icing path to retry the de-icing process and improve the system's fault tolerance and self-recovery capability.

[0120] In some embodiments, the de-icing recovery operation includes: Turn off the heating element and disconnect the ice-making branch 580; Restart the heating element, and after the first heating time of the heating element, control the ice-making branch 580 to switch to the de-icing path again; If the ice-making branch 580 switches to the de-icing path again for the duration of the second de-icing time, the heating element is turned off.

[0121] The first heating duration is the preheating time after the heating element is restarted during the de-icing recovery process and before switching to the de-icing path, which is used to ensure that the ice-making evaporator 581 reaches the initial temperature required for effective de-icing; the second de-icing duration is the duration for which the ice-making branch 580 maintains the de-icing state after re-entering the de-icing path, which is used to ensure that the ice is fully heated and detaches smoothly.

[0122] In this embodiment, after the initial de-icing failure, the heating element is first turned off and the ice-making branch 580 is disconnected to clear the abnormal state; then the heating element is turned on again for preheating, and after continuous heating for the first heating time, the ice-making branch 580 is switched to the de-icing path again to start a new round of de-icing; when the de-icing path runs for the second de-icing time, the system automatically turns off the heating element and ends the current recovery process, thereby improving the de-icing success rate and the overall reliability of the machine.

[0123] In some embodiments, after determining that the ice-making function of the ice maker 500 is normal, the method further includes: When the ice-making branch 580 switches to the de-icing path for the duration of the third de-icing time, the heating element is turned off.

[0124] In this embodiment, after confirming that the ice-making function of the ice maker 500 is normal, in order to prevent overheating or energy waste, the heating element can be automatically turned off when the ice-making branch 580 is in the de-icing passage state for a period of time that reaches the third de-icing time, thus ending the de-icing stage and preparing for the next ice-making cycle.

[0125] The following is a specific embodiment of an ice-making control method.

[0126] Refrigerators with rapid ice-making functions produce ice cubes through an immersion evaporator. To achieve the target ice-making speed, a suitable cooling capacity is required. When the ice-making time is constant, the cooling capacity should not be too small to avoid producing small ice cubes. On the other hand, the cooling capacity should not be too large, as this can cause the ice cubes to stick together. However, the refrigerator's cooling capacity output varies significantly with ambient temperature changes, resulting in large differences in ice cube size. Therefore, it is necessary to adjust the cooling capacity output according to ambient temperature changes to achieve the target ice-making speed. Thus, it is necessary to establish the relationship between the outlet temperature of the ice-making evaporator 581, the ice-making time, and the ice thickness.

[0127] Select a compressor with a speed of 810 that matches the ambient temperature to control the ice-making evaporation temperature within a stable range, such as between -18 and -22°C, and reduce the difference in cooling output, as shown in Table 1.

[0128] The relationship between ice-making time, evaporation temperature, and water temperature at a depth of ice finger insertion and a target ice weight of 5g-7g.

[0129] The relationship between heat flux density and evaporation temperature is fitted using experimental data on the variation of heat flux density (q) with evaporation temperature (T): q = 51.8774T 2 +1670.7T+22824; q: heat flux density, unit W / m³ 2 T: Evaporation temperature, unit C, Fitting type: Quadratic polynomial.

[0130] Fit metrics: R-squared (coefficient of determination): 0.91254 (indicating that the model can explain about 91.25% of the data variation, and the fit is good); RMSE (root mean square error): 178.08 (the average level of error).

[0131] The heat flux density varies with evaporation temperature, and the curve is fitted with a quadratic polynomial. As the evaporation temperature increases (from -21℃ to -16℃), the heat flux density decreases.

[0132] The fitting residual plot is the difference between the predicted value and the measured value, which can be used to observe the error distribution of the data points.

[0133] BP Neural Network Model: Schematic diagram of a BP neural network model for predicting freezing time. Input features: evaporation temperature, initial water temperature, required weight (weight of bullet ice); Model structure: two-layer neural network (with activation function); Output target: freezing time (i.e., the time required to make bullet ice).

[0134] A cubic surface fitting was performed on the freezing time of 6g bullet ice to fit the relationship between the freezing time (t) and the evaporation temperature (Te) and the initial water temperature (Tw). t: freezing time, in seconds (s); Te: evaporation temperature, in seconds (t). C, range: -25~-15℃; Tw: initial water temperature, unit C, range: 0~45℃, bullet ice weight: 5~7g. Cubic surface polynomial correlation t= 896.2308 182.3337Te 3.075Tw 8.9823Te 2 1.4792TeTw+0.073Tw 2 0.1377Te 3 0.0457Te 2 Tw+0.0014TeTw 2 0.0002Tw 3 Table 1

[0135] Fit performance metrics: Fit type: cubic surface polynomial; R-squared: 1 (indicating extremely high model fit to the data, almost perfect fit); RMSE: 0.28071 (extremely small error, almost negligible). The 3D surface plot shows the following: Horizontal axis: Te (evaporation temperature, -25 to -15℃), Tw (initial water temperature, 0 to 40℃); Vertical axis: t (freezing time, approximately 100 to 700 seconds). The lower the temperature and the lower the water temperature, the shorter the freezing time; conversely, the longer the freezing time.

[0136] Two types of modeling analyses were conducted regarding the icing process of bullet ice (6g specification): A quadratic polynomial fit was performed on the heat flux density-evaporation temperature relationship of the refrigeration system to characterize the variation of refrigeration capacity with evaporation temperature.

[0137] Two prediction models were established for freezing time: Cubic surface polynomial model: Using evaporation temperature and initial water temperature as input, it has a very high fitting degree (R²=1) and can directly calculate the freezing time of 6g bullet ice using the formula.

[0138] The BP neural network model incorporates the weight of ice as an additional input, making it more versatile and capable of predicting the freezing time of bullet ice of different weights within the range of 5g-7g.

[0139] This application also provides an ice-making control device for a refrigeration system.

[0140] The refrigeration equipment includes an ice maker 500, which includes an ice-making container 520 and an ice-making branch 580. The ice-making branch 580 is connected to the ice-making refrigeration system 800 of the refrigeration equipment. At least a portion of the ice-making evaporator 581 of the ice-making branch 580 extends into the ice-making container 520. The ice-making control equipment includes a temperature sensor and a controller.

[0141] The temperature sensor is used to obtain the current ambient temperature of the refrigeration equipment.

[0142] The controller is connected to the temperature sensor and is used to perform the following steps: Based on the current ambient temperature, a target compressor 810 speed matching the current ambient temperature is determined through a preset mapping relationship between the ambient temperature and the compressor 810 speed of the ice-making and refrigeration system 800. This mapping relationship is configured such that when the ambient temperature is less than 8°C, the compressor 810 speed is a first speed; when the ambient temperature is greater than 8°C and less than 40°C, the compressor 810 speed is increased in stages as the ambient temperature rises; and when the ambient temperature is greater than 40°C, the compressor 810 speed is a second speed, which is greater than the first speed. The compressor 810 is driven to operate at the target compressor speed, so that the temperature of the ice-making evaporator 581 is maintained at... 18℃ to Within a temperature range of 22℃, it outputs cooling capacity at the target ice-making rate.

[0143] According to the ice-making control device of the refrigeration equipment provided in the embodiments of this application, by establishing a mapping relationship between ambient temperature and compressor speed 810, the ice-making process of the refrigeration equipment is dynamically optimized, so that the ice-making evaporator 581 can be maintained in the working temperature range of -18℃ to -22℃, avoiding the instability of ice-making efficiency caused by ambient temperature fluctuations.
