[0002] Ice making equipment is a refrigeration mechanical equipment used to cool water below the freezing point and form ice cubes, and is widely used in many fields such as food processing, catering, medical treatment, and laboratories. According to different ice making principles and ice cube shapes, ice making equipment can be divided into pellet ice machines, flake ice machines, plate ice machines, tube ice machines, shell ice machines, etc. In the prior art, the ice making process usually requires manual operation by users. Taking a common ice making box as an example, the user needs to first take out the ice making box from the ice making equipment, then pour water into the ice making box, and then put the ice making box back into the equipment for ice making. For example, for the ice making function of some small ice makers or refrigerators, the user needs to pour water into the ice making tray in advance and then put it into the freezer for freezing. However, this manual ice making method has a cumbersome operation process. The user needs to frequently perform operations such as taking out the box, pouring water, and putting it back, which takes a long time.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The ice making control method of the ice making machine provided by the embodiment of the present invention is used to control the ice making machine. Figure 1 The ice maker includes: the ice maker 100 includes a cover assembly 10, an ice making assembly 20 and a control module (not shown).

[0043] Among them, a water injection space 11 is provided on the cover plate assembly 10, and at least one first water injection hole is provided on the side of the water injection space 11 facing the ice grid 21. The water injection space 11 is connected to the water supply end (not shown) through a water supply pipeline (not shown in the figure); an ice grid 21 is provided on the ice making assembly 20, and ice making grooves 21 are arranged on the ice grid 21.

[0044] The control module is connected to the cover assembly 10 and the ice-making assembly 20, and is used to receive a cover sealing instruction; in response to the cover sealing instruction, control the cover assembly to close to seal the ice-making assembly; control the water supply end to inject water into the ice grid on the ice-making assembly through the water injection space; when the amount of water in the ice grid meets a preset threshold, control the ice-making assembly to make ice.

[0045] In one embodiment, the ice-making assembly 20 may be transmission-connected to the cover assembly 10 via a driving mechanism (not shown in the figure) to control the cover assembly to be closed or opened.

[0046] Optionally, the ice tray 21 can be horizontally arranged in the ice maker, that is, the notch of the ice making groove 210 is vertically oriented. When the amount of water in the ice tray meets a preset threshold, such as when the ice making groove 210 is filled with water, the water in the ice making groove 21 overflows from bottom to top.

[0047] Optionally, the ice tray 21 can be vertically arranged in the ice maker, that is, the notch of the ice making groove 210 is horizontally oriented, or the angle between the notch of the ice making groove 210 and the horizontal direction does not exceed 5°. At this time, the cover assembly 10 injects water into the ice making groove 210 from the side of the ice tray 21.

[0048] Optionally, the control module includes: a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the ice-making control method of the ice maker in this application are implemented. The method includes: receiving a cover sealing instruction; in response to the cover sealing instruction, controlling the cover assembly to close to seal the ice-making assembly; controlling the water supply end to inject water into the ice grid on the ice-making assembly through the water injection space; when the water volume in the ice grid meets a preset threshold, controlling the ice-making assembly to make ice. In this application, by responding to the cover sealing instruction, controlling the cover assembly to seal the ice-making assembly, and injecting water into the ice grid on the ice-making assembly through the water injection space on the cover assembly, and controlling the ice-making after the water volume in the ice grid reaches the preset threshold, it ensures that the water volume for each ice-making is consistent, avoiding the situation of extended ice-making time or poor ice quality caused by too much or too little water volume. The process of automatic water injection and ice-making does not require manual waiting and intervention, which is beneficial for the ice maker to perform ice-making operations quickly and continuously, improving the ice-making efficiency.

[0049] Optionally, as Figure 2 shown, the ice-making control method of the ice maker in this application is implemented through the intelligent device 300. The intelligent device 300 is communicatively connected to the ice maker 100 through the network 200. The intelligent device 300 is used for: receiving a cover sealing instruction; in response to the cover sealing instruction, controlling the cover assembly to close to seal the ice-making assembly; controlling the water supply end to inject water into the ice grid on the ice-making assembly through the water injection space; when the water volume in the ice grid meets a preset threshold, controlling the ice-making assembly to make ice.

[0050] The intelligent device includes but is not limited to: various personal computers, laptop computers, smartphones, tablet computers, portable wearable devices, intelligent gateways, and servers.

[0051] The present invention will be described in detail below through specific embodiments.

[0052] Please refer to Figure 3 shown, Figure 3 which is a schematic flowchart of the ice-making control method of the ice maker provided by the embodiment of the present invention. The method is used to control the ice maker as Figure 1 shown;

[0053] The method includes:

[0054] S1: Receive a cover sealing instruction.

[0055] Among them, the cover sealing instruction can be a signal sent by the user or the control module of the ice maker, used to instruct the cover assembly of the ice maker to close and seal the ice-making assembly.

[0056] Optionally, in a household scenario, the user can manually issue a cover sealing instruction through the control panel of the ice maker. For example, when the user needs to make ice, pressing the "Start Making Ice" button will cause the ice maker to automatically issue a cover sealing instruction to indicate closing the cover assembly and sealing the ice making assembly through the cover sealing instruction.

[0057] Optionally, in a commercial scenario (such as in restaurants, bars, milk tea shops, etc.), the granular ice, ice cubes, etc. prepared by the ice maker can be stored in a preset space (such as an ice bucket). When the ice amount in the preset space is detected by an infrared sensor to be lower than a preset threshold, the infrared sensor sends a signal to the ice maker through a wired or wireless network, so that the control module of the ice maker automatically issues a cover sealing instruction to indicate closing the cover assembly and sealing the ice making assembly through the cover sealing instruction. Further, when the ice maker receives the signal from the infrared sensor, it can detect whether the current time is in a preset busy period; if so, it automatically issues a cover sealing instruction; if not, it waits until the current time reaches the busy period and then automatically issues a cover sealing instruction.

[0058] S2: In response to the cover sealing instruction, control the cover assembly to close to seal the ice making assembly.

[0059] The control module of the ice maker responds to the cover sealing instruction and controls the cover assembly to close to seal the ice making assembly.

[0060] S3: Control the water supply end to inject water into the ice grid on the ice making assembly through the water injection space.

[0061] After the cover assembly is closed, a signal indicating that the cover assembly closing is completed is sent to the control module of the ice maker. In response to this signal, the control module starts the water supply end to inject water into the water injection space to inject water into the ice grid on the ice making assembly through the water injection space.

[0062] S4: When the water amount in the ice grid meets the preset threshold, control the ice making assembly to make ice.

[0063] Among them, the preset threshold can be a water volume threshold determined by the ice amount required by the user. The cover sealing instruction can include the ice amount required by the user.

[0064] Exemplarily, the preset threshold can be determined according to the following formula:

[0065]

[0066] Among them, V 水 is the water volume threshold, and V 冰 is the ice amount required by the user.

[0067] For example, when the amount of ice required by the user is 100 cubic meters, the calculated water volume threshold is 91.99 cubic meters. Thus, when the water volume in the ice grid is detected to reach 92 cubic meters, the water supply end is closed and the ice maker is controlled to make ice.

[0068] In one embodiment, at least one first water injection hole is provided on one side of the water injection space facing the ice grid. The control of the water supply end to inject water into the ice grid on the ice making assembly through the water injection space includes:

[0069] During the process of controlling the water supply end to inject water into the ice grid on the ice making assembly through the water injection space, the water level in the water injection space is monitored in real time;

[0070] Based on the water level in the water injection space, the water injection flow rate and / or the water injection speed of the water supply end injecting water into the ice grid on the ice making assembly through the water injection space are dynamically adjusted;

[0071] Based on the water injection flow rate and / or the water injection speed, water is injected into the ice grid through the at least one first water injection hole.

[0072] In one embodiment, a liquid level sensor for measuring the water level of the water injection space is installed at the bottom or side of the water injection space. The liquid level sensor transmits the real-time measured water level data to the control module of the ice maker through a wireless network or a wired connection. A control valve and a variable frequency pump are provided at the water delivery end. The control module is connected to the control valve and the variable frequency pump at the water delivery end for controlling the opening degree of the water delivery end through the control valve and the water injection speed of the water delivery end to the water injection space 11 through the variable frequency pump. The processor in the control module of the ice maker can be a PLC (programmable logic controller) or a microcontroller, which can process and analyze sensor data. The PID (Proportional-Integral-Derivative) control algorithm is used to dynamically adjust the water injection flow rate and speed. The PID algorithm is a commonly used feedback control system algorithm that can adjust the control quantity (water injection flow rate and / or water injection speed) according to the deviation between the set value (target water level) and the actual measured value (current water level), and realizes the adjustment of the water injection flow rate and speed by controlling the opening degree of the flow control valve or the rotation speed of the variable frequency pump. For example, when the water level is lower than the preset threshold, the flow rate is increased, such as increasing the opening degree of the control valve at the water delivery end or increasing the rotation speed of the variable frequency pump at the water delivery end; when the water level is close to the preset threshold, the flow rate is decreased, such as decreasing the opening degree of the control valve or decreasing the rotation speed of the variable frequency pump. A plurality of first water injection holes are provided at the bottom of the water injection space to ensure that water can flow into the ice tray evenly. The layout and quantity of the first water injection holes can be set according to the distribution and shape of the ice tray to achieve the best water injection effect. Water injection process control: According to the dynamically adjusted water injection flow rate and / or water injection speed, precisely control the water injection process of each first water injection hole. Ensure that water can flow into the ice tray smoothly and evenly, avoiding splashing or forming bubbles. Among them, the first water injection hole represents the channel for the water injection space 11 to inject water into the ice tray 21.

[0073] Exemplarily, assume that one side of the water injection space facing the ice tray is provided with 16 first water injection holes evenly distributed, the diameter of each hole is 3 mm, and each first water injection hole corresponds to an ice-making groove in the ice tray; the adjustment strategy for the water injection flow rate and speed by controlling the opening of the flow control valve or the speed of the variable-frequency pump is as follows: The water level is lower than the preset threshold: If the current water level is lower than 80% of the target water level, the control module increases the opening of the flow control valve to 100% and increases the speed of the variable-frequency pump to the maximum value to inject water quickly. The water level is close to the preset threshold: If the current water level is between 80% and 95% of the target water level, the control module adjusts the opening of the flow control valve to 50% and reduces the speed of the variable-frequency pump to medium speed to inject water smoothly. The water level is close to the target water level: If the current water level is above 95% of the target water level, the control module adjusts the opening of the flow control valve to 20% and reduces the speed of the variable-frequency pump to the lowest value to inject water slowly to avoid the water level exceeding the target value. When the water level reaches the target water level, the control module closes the flow control valve and the variable-frequency pump to stop water injection. During this process, the water in the water injection space flows evenly into the ice tray through 16 first water injection holes. Through the PID control algorithm, the water injection process is very precise, and the water level can reach the target value stably, avoiding water level fluctuations. Due to the reasonable layout of the water injection holes, the water can flow evenly into the ice tray, ensuring the consistency of the shape and size of the ice cubes. Dynamically adjusting the water injection flow rate and speed reduces unnecessary energy consumption and improves the ice-making efficiency. For example, assume that the target water level is 10 cm, the measurement accuracy of the liquid level sensor is 0.1 cm, and the PID control parameters are k p = 1.2, k i = 0.5, k d = 0.1. Initial stage: The water level is 0 cm, lower than 80% (8 cm) of the target water level, the opening of the flow control valve is 100%, and the speed of the variable-frequency pump is the maximum. Intermediate stage: The water level reaches 8 cm, between 80% and 95%, the opening of the flow control valve is adjusted to 50%, and the speed of the variable-frequency pump is reduced to medium. Approaching the target stage: The water level reaches 9.5 cm, above 95%, the opening of the flow control valve is adjusted to 20%, and the speed of the variable-frequency pump is the lowest. Completion stage: The water level reaches 10 cm, stops water injection, and starts ice-making. Through this precise control method, the ice-making machine can efficiently and stably complete the water injection and ice-making processes, ensuring the quality and consistency of the ice cubes.

[0074] In one embodiment, at least one nozzle is provided on one side of the water injection space facing the ice tray, and the control of the water injection from the water delivery end to the ice tray on the ice-making assembly through the water injection space includes:

[0075] During the process of controlling the water injection from the water delivery end to the ice tray on the ice-making assembly through the water injection space, the water level of the water injection space is monitored in real time;

[0076] When the water level in the water injection space reaches a preset water level threshold, a nozzle start instruction is generated;

[0077] In response to the nozzle start instruction, start the at least one nozzle to inject water into the ice tray.

[0078] Exemplarily, it is assumed that there are at least one nozzle provided in the water injection space facing the ice tray, and the nozzle is used to spray water flow onto the ice tray to ensure uniform water injection. The liquid level sensor in the water injection space is used to monitor the water level in the water injection space in real time. The control module, such as a PLC or a microcontroller, is used to process the sensor data and execute the control logic. The water delivery end includes a water pump and a flow control valve, which are used to adjust the water injection flow rate and speed. The user starts the ice making program, and the control module opens the flow control valve and the water pump to start injecting water into the water injection space. The position sensor monitors the water level in the water injection space in real time and transmits the data to the control module. Dynamically adjust the water injection flow rate and speed: The control module calculates the water injection flow rate and speed that need to be adjusted using the PID algorithm based on the water level data fed back by the liquid level sensor. When the water level is lower than the preset threshold, the control module increases the opening of the flow control valve or raises the rotation speed of the water pump. When the water level approaches the preset threshold, the control module decreases the opening of the flow control valve or lowers the rotation speed of the water pump. In one embodiment, it is also possible to inject water into the water injection space at a customized water injection flow rate and water injection speed. Start nozzle water injection: When the water level in the water injection space reaches the preset water level threshold, the control module generates a nozzle start instruction. In response to the nozzle start instruction, the control module starts the nozzle and sprays water flow onto the ice tray through the nozzle. The layout and quantity of the nozzles are set according to the distribution and shape of the ice tray to ensure that water can flow into the ice tray evenly. Water injection completion: When the water volume in the ice tray meets the preset threshold, the control module closes the flow control valve and the water pump to stop water injection. The nozzle stops spraying water, the water injection process ends, and ice making begins.

[0079] It is assumed that the ice tray is a 10×10 matrix, the size of each ice tray is 2 cm×2 cm, and there are a total of 100 ice making slots. 10 nozzles are evenly distributed on the side of the water injection space facing the ice tray, and each nozzle corresponds to a row of ice making slots. The flow rate of each nozzle is 0.5 liters per minute. The working pressure of the nozzle is 3 bar to ensure that the water flow can be sprayed evenly. The preset water level threshold is 10 cm, which means that when the water level in the water injection space reaches 10 cm, the nozzle is started. After the water volume in the water injection space reaches 10 cm, the control module receives the indication of the liquid level sensor and generates a nozzle start instruction to inject water into the ice tray through the nozzle. In response to the nozzle start instruction, the control module starts the nozzle and sprays water flow onto the ice tray through the nozzle to inject water into the ice tray until the water volume in the ice tray meets the preset threshold.

[0080] During the process of the nozzle spraying water flow onto the ice tray, the ice making component can be started to make ice simultaneously to form bubble ice. In one embodiment, the generating the nozzle start instruction includes:

[0081] Obtain the bubble content of the ice cubes;

[0082] Determine a target spraying mode from a preset spraying mode of the nozzle based on the bubble content of the ice cubes;

[0083] Generate a nozzle start command according to the target spraying mode.

[0084] The user can preset the bubble content of the ice cubes through the display panel of the ice maker. The control module receives this bubble content and determines the target spraying mode from the preset spraying modes of the nozzles, thereby generating the nozzle start command.

[0085] Assume that the ice tray is a 10×10 matrix, the size of each ice cell is 2 cm×2 cm, and there are a total of 100 ice cells. 10 nozzles are evenly distributed at the bottom of the water injection space, and each nozzle corresponds to a row of ice cells. The spraying modes of the nozzles include Mode 1, Mode 2, and Mode 3. Mode 1: Low bubble content, the nozzle sprays at a low flow rate and high frequency (e.g., flow rate: 0.3 L / min; spraying frequency: 10 times / second), suitable for making clear ice cubes. Mode 2: Medium bubble content, the nozzle sprays at a medium flow rate and medium frequency (e.g., flow rate: 0.5 L / min, spraying frequency: 5 times / second), suitable for making ice cubes with a small amount of bubbles. Mode 3: High bubble content, the nozzle sprays at a high flow rate and low frequency (flow rate: 0.8 L / min, spraying frequency: 2 times / second), suitable for making ice cubes with rich bubbles. If the bubble content of the ice cubes set by the user is low bubble content, the target spraying mode is Mode 1.

[0086] In one embodiment, a bubble content detection device (such as an optical sensor or an ultrasonic sensor) can be provided on the side of the water injection space facing the ice tray to detect the bubble content in the ice cubes in the ice tray. The control module dynamically adjusts the spraying flow rate and spraying frequency of the nozzle according to the detected bubble content so that the bubble content in the ice cubes meets the bubble content of the ice cubes set by the user.

[0087] In this embodiment, according to the bubble content of the ice cubes set by the user, a suitable spraying mode is selected to make ice cubes with different bubble contents to meet the user's needs.

[0088] In one embodiment, a second water injection hole is provided on the ice tray, and the second water injection hole can be connected to the water delivery end through a water pipe. The ice making control method of the ice maker further includes:

[0089] Control the water delivery end to inject water into the ice cells on the ice making component through the second water injection hole.

[0090] Among them, the second water injection hole represents a channel that connects to the water delivery end and can inject water into the ice tray. The second water injection hole can be arranged on the side of the ice tray, and a switch valve is arranged at the second water injection hole to control the on-off of the second water injection hole. When receiving the cover plate sealing instruction, it can respond to the cover plate sealing instruction, control the cover plate assembly to close to seal the ice making assembly. When receiving the instruction that the cover plate assembly sealing is completed, the control module generates a water injection instruction. In response to the water injection instruction, the control module starts the water delivery end and starts the water injection function of the second water injection hole (start the switch valve that controls the on-off of the second water injection hole) to inject water into the ice tray on the ice making assembly through the second water injection hole. The number of the second water injection holes can be one or more.

[0091] For example, the ice tray is a 10*1 matrix, the size of each ice making groove is 2*5*1 cm, and there are 10 ice making grooves in total. A second water injection hole is arranged on the side of each ice making groove. When receiving the cover plate sealing instruction, it can respond to the cover plate sealing instruction, control the cover plate assembly to close to seal the ice making assembly. When receiving the instruction that the cover plate assembly sealing is completed, the control module generates a water injection instruction. In response to the water injection instruction, the control module starts the water delivery end and starts the water injection function of the second water injection hole (such as starting the switch valve that controls the on-off of the second water injection hole) to inject water into each corresponding ice making groove through the second water injection hole. When the water flow rate of each second water injection hole (which can be detected by setting a flow meter on the water pipe connecting the second water injection hole) reaches the preset threshold value, the water delivery end and the water injection function of the second water injection hole are closed, and ice making is started. The method of injecting water through the second water injection hole on the ice tray can reduce the sputtering and bubble formation of water in the ice tray, make the ice cubes more transparent, thereby improving the purity and hardness of the ice cubes, making the ice cubes not easy to break during use, and prolonging the service life of the ice cubes.

[0092] In an embodiment, a third water injection hole and a water outlet hole are arranged on the ice tray, and a first water pump is arranged at the third water injection hole. The method further includes:

[0093] Obtain a water injection instruction;

[0094] In response to the water injection instruction, start the first water pump to control the water delivery end to inject water into the ice tray on the ice making assembly through the third water injection hole. At the same time, control the water flow in the ice tray to flow to the water outlet hole to realize the flowing circulation of the water in the ice tray, and during the flowing circulation process, control the ice making assembly to make ice.

[0095] Among them, the third water injection hole is connected to the water delivery end, and the water outlet hole can be connected to a water storage bucket. The water in the water storage bucket can be used as domestic water. Switch valves are respectively arranged on the third water injection hole and the water outlet hole. The control module controls the on-off of the water flow through the switch valves. The third water injection hole represents the channel for the water delivery end to inject water into the ice tray, and the water outlet hole serves as the channel for the water in the ice tray to flow out. The temperature of the input water at the water delivery end can be set, such as set at 0.5 degrees, that is, the temperature of the input water at the water delivery end when injecting into the ice tray is about 0.5 degrees. The first water pump is arranged on the connecting pipeline between the third water injection hole and the water delivery end. The control module is connected to the first water pump and pressurizes at one end of the third water injection hole through the first water pump, so that the water in the ice-making groove of the ice tray flows to one end of the water outlet hole, so as to realize the flowing circulation of the water in the ice tray.

[0096] The user sends a cover plate sealing instruction to the ice maker through the control panel or remotely. When receiving the instruction that the cover plate assembly is sealed, the control module generates a water injection instruction. In response to the water injection instruction, the control module starts the first water pump, the switch valve of the third water injection hole and the switch valve of the water outlet hole to control the water delivery end to inject water into the ice tray on the ice-making assembly through the third water injection hole. At the same time, the water in the ice-making groove of the ice tray flows to the water outlet hole, so as to realize the flowing circulation of the water in the ice tray, and during the flowing circulation process, control the ice-making assembly to make ice.

[0097] For example, refer to Figure 4 , the ice tray is a 10*1 matrix, the size of each ice-making groove is 2*10*1 cm, and there are a total of 10 ice-making grooves. The adjacent ice-making grooves in this column of ice-making grooves are connected through a channel 250. The third water injection hole A1 and the water outlet hole A2 opposite to the third water injection hole are arranged on the side of this column of ice-making grooves. When receiving the cover plate sealing instruction, it can respond to the cover plate sealing instruction, control the cover plate assembly to close to seal the ice-making assembly. When receiving the instruction that the cover plate assembly is sealed, the control module generates a water injection instruction. In response to the water injection instruction, the control module starts the water delivery end (not shown in the figure), the first water pump 240, the switch valve 220 of the third water injection hole and the switch valve 230 of the water outlet hole to control the water delivery end to inject water into the first ice-making groove 210-1 of the ice tray on the ice-making assembly through the third water injection hole 220. At the same time, the water in the ice tray flows through the ice-making grooves in sequence and flows out through the water outlet hole A2 on the ice-making groove 210-2, so as to realize the flowing circulation of the water in the ice tray, and during the flowing circulation process, control the ice-making assembly to make ice.

[0098] For example, the ice tray is a 10*2 matrix, and the size of each ice-making slot is 1*1*1 cm, with a total of 20 ice-making slots. Third water injection holes are provided on the side of each column of ice-making slots, and water outlet holes are provided opposite to the third water injection holes. Water flow holes are provided on the partition between adjacent ice-making slots in each column of ice-making slots, which can allow water to flow from the first ice-making slot in each column of ice-making slots to the last ice-making slot and flow out through the water outlet holes. When receiving the cover plate sealing instruction, it can respond to the cover plate sealing instruction, control the cover plate assembly to close to seal the ice-making assembly. When receiving the instruction that the cover plate assembly sealing is completed, the control module generates a water injection instruction. In response to the water injection instruction, the control module starts the first water pump, the on-off valve of the third water injection hole and the on-off valve of the water outlet hole to control the water delivery end to inject water into the ice tray on the ice-making assembly through the third water injection hole. At the same time, the water in the ice-making slots in the ice tray flows to the water outlet hole to realize the flowing circulation of the water in the ice tray. And during the flowing circulation process, the control module controls the ice-making assembly to make ice. When the preset ice-making time (which can be obtained from the cover plate sealing instruction) is reached, the water delivery end, the first water pump, the on-off valve of the third water injection hole and the on-off valve of the water outlet hole are started. In this embodiment, the heat in the ice tray can be quickly taken away by the external circulating water flow, accelerating the freezing process of the water and reducing the bubbles and impurities in the ice tray, making the ice cubes more transparent.

[0099] In one embodiment, an internal circulation water path is provided in the ice tray, and a second water pump is provided on the internal circulation water path. When the water volume in the ice tray meets the preset threshold, controlling the ice-making assembly to make ice includes:

[0100] When the water volume in the ice tray meets the preset threshold, a water pump start instruction is generated;

[0101] Based on the water pump start instruction, the second water pump is started to make the water in the ice tray flow through the internal circulation water path for flowing circulation. During the flowing circulation process, the ice-making assembly is controlled to make ice.

[0102] The control module responds that the water volume in the ice tray meets the preset threshold and generates a water pump start instruction. Responding to this water pump start instruction can start the second water pump to make the water in the ice tray flow through the internal circulation water path for flowing circulation. During the flowing circulation process, the ice-making assembly is controlled to make ice.

[0103] For example, please refer to Figure 5, the ice tray 21 is a 10*1 matrix, and the size of each ice-making slot 210 is 1*1*1 cm, with a total of 10 ice-making slots. The adjacent ice-making slots in this column of ice-making slots are connected through a channel 250. One end of the internal circulation waterway 270 is connected to the water inlet hole B1 of the first ice-making slot 210-1, and the other end is connected to the water outlet hole B2 of the last ice-making slot 210-2 in this column. Thus, after starting the water pump 260, it is possible to achieve a flowing circulation through the internal circulation waterway 270, and during the flowing circulation process, control the ice-making component to make ice. After starting the water pump 260, the water in the ice tray is pressurized, and the water flows through each ice-making slot in sequence from the last ice-making slot 210-2, and finally flows into the first ice-making slot 210-1, forming a closed-loop cycle. The water continuously circulates in the ice tray, ensuring uniform cooling of the water, reducing bubbles and impurities, and improving the transparency and quality of the ice cubes.

[0104] Optionally, before starting the second water pump, sufficient water can be reserved in the water pump and the water in the water pump can be replaced regularly to ensure the water quality, ensure that the water level is not lower than the lowest safe water level, prevent the water pump from dry burning, extend the service life of the water pump, and ensure the safe operation of the water pump.

The process of automatic water injection and ice-making does not require manual waiting and intervention, which is beneficial for the ice maker to perform ice-making operations quickly and continuously, and improves the ice-making efficiency.
