Description

Technical Field

[0001] The present application relates to the technical field of ice maker control, and specifically relates to a control method and device for an ice maker, an electronic device, and a storage medium. Background Art

[0002] An ice maker is a device widely used in commercial, industrial, and household fields, capable of efficiently and automatically producing ice cubes. Among them, the crescent ice maker is favored by the market due to its unique ice cube shape and high ice production efficiency. However, under low-temperature working conditions, such as when the ambient temperature is low or the inlet water temperature is low, the ice maker is prone to the problem that the ice cubes cannot fall off the ice making plate during the defrosting process, seriously affecting the stability and reliability of the device.

[0003] Traditional ice makers usually rely on hot gas bypass or inlet water heating to provide the heat required for defrosting during the defrosting stage. However, in a low-temperature environment, a single heat source may not be able to meet the defrosting requirements. Especially for crescent ice makers, their ice making plate structure is special, and the contact area between the ice cubes and the ice making plate is large. If the defrosting heat is insufficient, the ice cubes are extremely likely to remain on the ice making plate. If the defrosting fails, when the ice maker enters the next ice making cycle, the newly formed ice cubes will adhere to the ice cubes that have not fallen off, forming a multiple ice making phenomenon. As the ice cubes continue to accumulate, it may eventually cause the entire plate of ice cubes to lock the ice making plate, not only affecting normal ice making, but also potentially causing damage to the ice making plate due to ice cube expansion or continuous operation of the compressor, and even triggering equipment failures.

[0004] In the prior art, some ice makers use methods such as extending the defrosting time or increasing the hot gas temperature to improve the defrosting effect, but this method may lead to increased energy consumption and cannot completely avoid the defrosting failure problem under low-temperature working conditions. Summary of the Invention

[0005] The present application provides a control method for an ice maker to improve the defrosting effect and avoid equipment failures caused by ice cubes locking the ice making plate.

[0006] In a first aspect, the present application provides a control method for an ice maker, characterized in that the ice maker includes a compressor, a condenser, a defrosting valve, an evaporator, an ice making plate, a water inlet valve, and a water tank, the defrosting valve is installed between the compressor and the evaporator, and the method includes: Opening the water inlet valve in response to an ice making control signal, and receiving the water injection level of the water tank; When the water injection level reaches a preset ice making level, starting ice making and obtaining the dynamic ice making level of the water tank; When the dynamic ice making level is less than or equal to a first preset water level threshold, generating a first defrosting signal based on a first preset defrosting duration and starting defrosting; Obtain the first temperature value at the outlet of the evaporator when the first preset defrosting duration ends, and compare the first temperature value with the first preset temperature threshold; When the first temperature value is greater than or equal to the first preset temperature threshold, generate an ice-making control signal and perform the step of starting ice-making in response to the ice-making control signal; When the first temperature value threshold is less than the first preset temperature threshold, generate a defrosting signal based on the first temperature value and start defrosting until the temperature value at the outlet of the evaporator is greater than or equal to the first preset temperature threshold.

[0007] By adopting the above technical solution, the ice maker first responds to the ice-making control signal to open the water inlet valve, receives the water injection level of the water tank, and starts ice-making and obtains the dynamic ice-making water level when the water injection level reaches the preset ice-making water level, which can ensure that there is an appropriate amount of water during the ice-making process. First, judge whether to start defrosting according to the dynamic ice-making water level, perform the first defrosting for the first preset defrosting duration, and then decide subsequent operations based on the comparison result between the temperature value at the outlet of the evaporator and the first preset temperature threshold. During the defrosting process, obtain the first temperature value at the outlet of the evaporator when the first preset defrosting duration ends and compare it with the first preset temperature threshold, and take different measures according to the comparison result: if the first temperature value is greater than or equal to the first preset temperature threshold, generate an ice-making control signal to restart ice-making to ensure the smooth cycle of the ice-making process; if the first temperature value threshold is less than the first preset temperature threshold, generate a cyclic defrosting signal and continue defrosting until the temperature value at the outlet of the evaporator reaches the standard, effectively ensuring the defrosting effect and avoiding situations such as ice blocks jamming the ice-making plate and affecting normal ice-making, or even causing equipment failures.

[0008] Optionally, the generating a defrosting signal based on the first temperature value and starting defrosting until the temperature value at the outlet of the evaporator is greater than or equal to the first preset temperature threshold includes: Compare the first temperature value with a second preset temperature threshold. When the first temperature value is greater than or equal to the second preset temperature threshold, generate a second defrosting signal according to the first preset duration and start defrosting; Obtain the second temperature value at the outlet of the evaporator when the first preset ice duration ends, and compare the second temperature value with the first preset temperature threshold; When the second temperature value is greater than or equal to the first preset temperature threshold, generate an ice-making control signal and perform the step of starting ice-making in response to the ice-making control signal; When the second temperature is less than the first preset temperature threshold, generate a defrosting signal according to a third preset defrosting duration and start defrosting; Obtain the third temperature value at the outlet of the evaporator when the third preset defrosting duration ends, and compare the third temperature value with the first preset temperature threshold; When the third temperature threshold is greater than or equal to the first preset temperature threshold, generate an ice-making control signal and perform the step of starting ice-making in response to the ice-making control signal; When the third temperature threshold is less than the first preset temperature threshold, perform defrosting for the first preset number of defrosting times according to the third preset defrosting duration; Obtain the fourth temperature value at the outlet of the evaporator when the defrosting for the first preset number of defrosting times is completed, and compare the fourth temperature value with the first preset temperature threshold; If the fourth temperature value is greater than or equal to the first preset temperature threshold, generate an ice-making control signal and perform the step of starting ice-making in response to the ice-making control signal; If the fourth temperature threshold is less than the first preset temperature threshold, generate a fault alarm signal and trigger an alarm.

[0009] By adopting the above technical solution, the defrosting strategy is flexibly adjusted according to different defrosting situations, effectively solving the problem that ice cubes cannot fall off the ice-making plate under low-temperature conditions, avoiding the phenomenon of multiple ice-making and the situation where ice cubes are locked to the ice-making plate, and ensuring the stability and reliability of the ice maker. At the same time, when the temperature at the outlet of the evaporator still does not meet the standard after multiple defrostings, a fault alarm signal is generated and an alarm is triggered, which can timely remind the maintenance personnel to handle it and prevent further damage to the equipment.

[0010] Optionally, the step of generating a defrosting signal according to the first temperature value and starting defrosting until the temperature value at the outlet of the evaporator is greater than or equal to the first preset temperature threshold further includes: When the first temperature value is less than the second preset temperature threshold, generate a fifth defrosting signal according to the second preset duration and start defrosting, where the second preset duration is greater than the first preset duration; Obtain the fifth temperature value at the outlet of the evaporator when the second preset duration ends, and compare the fifth temperature value with the first preset temperature threshold; If the fifth temperature value is greater than or equal to the first preset temperature threshold, generate an ice-making control signal and perform the step of starting ice-making in response to the ice-making control signal; If the fifth temperature value is less than the first preset temperature threshold, perform defrosting for the second preset number of defrosting times according to the second preset duration; Obtain the sixth temperature value at the outlet of the evaporator when the defrosting for the second preset number of defrosting times is completed, and compare the sixth temperature value with the first preset temperature threshold; If the sixth temperature value is greater than or equal to the first preset temperature threshold, generate an ice-making control signal and perform the step of starting ice-making in response to the ice-making control signal; If the sixth temperature threshold is less than the first preset temperature threshold, generate a fault alarm signal and trigger an alarm.

[0011] By adopting the above technical solution, when the first temperature value is less than the second preset temperature threshold, defrosting is performed for a second preset duration greater than the first preset duration, which can perform defrosting more effectively and avoid insufficient defrosting caused by too low temperature. By comparing the temperature values at the evaporator outlet in different defrosting stages with the first preset temperature threshold multiple times, it can ensure that the ice maker resumes ice making at an appropriate temperature. If the first preset temperature threshold is still not reached after multiple defrostings, a fault alarm signal is triggered, which can promptly detect the abnormal situation of the ice maker and remind for handling, thus ensuring the normal operation of the ice maker.

[0012] Optionally, a blower is provided at the condenser. After starting ice making in response to the ice making control signal, the following steps are further included: Obtain the current condensation temperature at the condenser outlet, and compare the current condensation temperature with a preset condensation temperature threshold; When the condensation temperature is greater than or equal to the preset condensation temperature threshold, turn on the blower.

[0013] By adopting the above technical solution, it is possible to decide whether to turn on the blower according to the comparison result between the current condensation temperature at the condenser outlet and the preset condensation temperature threshold, realizing effective control of the heat dissipation of the air-cooled condenser, avoiding the influence of too high condensation temperature on the performance of the ice maker, and ensuring the stable operation of the ice maker. That is, when the current condensation temperature at the condenser outlet is too high, the blower is turned on so that the ice making plate can obtain the maximum cooling capacity.

[0014] Optionally, before generating the first defrost signal based on the first preset defrost duration and starting the first defrost, the following steps are further included: Generate an ice making stop signal, and based on the ice making stop signal, turn off the blower within a preset conversion duration.

[0015] By adopting the above technical solution, after ice making is completed, formal defrosting starts after a preset conversion duration, avoiding the continuous operation of the blower from affecting the defrosting process, ensuring normal defrosting, and improving the ice making efficiency and stability.

[0016] Optionally, the ice maker further includes a flushing pipe installed above the ice making plate and a water pump connecting the flushing pipe and the water tank. Before generating the ice making control signal and performing the step of starting ice making in response to the ice making control signal, the following steps are further included: Generate a flushing signal and turn on the water pump, and based on the flushing signal, control the water pump to pump water from the water tank to flush the ice making plate within a preset flushing duration.

[0017] By adopting the above technical solution, before defrosting is completed and the next round of ice making is started, the water pump is used to pump water from the water tank to flush the ice making plate through the flushing pipe, which can clean the ice making plate, remove impurities and residual ice on the surface of the ice making plate, ensure the subsequent ice making quality, and improve the ice making effect.

[0018] Optionally, the ice maker further includes a drain valve installed on the water tank, and the method further includes: Obtaining the current number of ice-making times, and comparing the current number of ice-making times with a preset ice-making round threshold; When the current number of ice-making times reaches the preset ice-making round threshold, opening the drain valve.

[0019] By adopting the above technical solution, when the current number of ice-making times reaches the preset ice-making round threshold, the drain valve is opened to pump out the water in the water tank, realizing regular water change, ensuring the quality of ice-making water, and thus improving the ice-making quality.

[0020] In a second aspect of the present application, a control device for an ice maker is provided, which is applied to an ice maker. The ice maker includes a controller, a compressor, a condenser, a defrosting valve, an evaporator, an ice-making plate, a water inlet valve, and a water tank.

The device includes: A signal response module, configured to respond to an ice-making control signal to open the water inlet valve and receive the water injection level of the water tank; An ice-making start module, configured to start ice-making when the water injection level reaches a preset ice-making water level, and obtain the dynamic ice-making water level of the water tank; A defrosting start module, configured to generate a first defrosting signal based on a first preset defrosting duration and start defrosting when the dynamic ice-making water level is less than or equal to a first preset water level threshold; A numerical comparison module, configured to obtain a first temperature value at the outlet of the evaporator when the first preset defrosting duration ends, and compare the first temperature value with a first preset temperature threshold; A signal generation unit, configured to generate an ice-making control signal when the first temperature value is greater than or equal to the first preset temperature threshold, and execute the step of starting ice-making in response to the ice-making control signal; A defrosting adjustment unit, configured to generate a defrosting signal based on the first temperature value and start defrosting when the first temperature value threshold is less than the first preset temperature threshold until the temperature value at the outlet of the evaporator is greater than or equal to the first preset temperature threshold.

[0025] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0026] In the description of the embodiments of the present application, words such as "for example" or "for illustration" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "for example" or "for illustration" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "for example" or "for illustration" is intended to present relevant concepts in a specific manner.

[0027] In the description of the embodiments of the present application, the meaning of the term "plurality" refers to two or more. For example, a plurality of systems refers to two or more systems, and a plurality of screen terminals refers to two or more screen terminals. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the technical features indicated. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. The terms "comprise", "include", "have" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0028] In the embodiments of the present application, the ice maker includes a controller, a compressor, a condenser, an expansion valve, an expansion valve temperature sensing package, an evaporator, an ice making plate, a water inlet valve, a dehydration valve, and a water tank. The compressor, the condenser, the expansion valve, the expansion valve temperature sensing package, the evaporator, the water inlet valve, the dehydration valve, the water pump, and the drain valve are all electrically connected to the controller.

[0029] Refer to Figure 1 , which is a schematic framework diagram of the ice making process of the ice maker in the embodiments of the present application. As Figure 1As shown, the ice maker includes an ice-making state and a defrosting state. In the ice-making state, the water inlet valve is opened to inject water required for ice-making into the water tank. The water level in the water tank is detected in real time by a water monitoring sensor installed in the water tank. After the water volume in the water tank is sufficient for ice-making, the water inlet valve is closed. At the same time, the compressor operates to compress the refrigerant into a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant is condensed by the condenser to form a medium-temperature and high-pressure liquid refrigerant. The liquid refrigerant enters the evaporator through a drying filter and an expansion valve. The temperature of the evaporator outlet is monitored by a temperature sensing bulb of the expansion valve installed at the evaporator outlet to adjust and control the opening degree of the expansion valve. The liquid refrigerant in the evaporator evaporates into a gaseous refrigerant by absorbing the heat of the water flowing through the ice-making plate, so that the water in the ice-making plate is transformed into ice cubes, completing ice-making. The gaseous refrigerant formed by evaporation in the evaporator flows out from the outlet of the evaporator and circulates back to the compressor. During the process of the gaseous refrigerant circulating to the compressor, it exchanges heat with the liquid refrigerant discharged from the condenser. The liquid refrigerant coming out of the condenser is further cooled by the low-temperature gas at the evaporator outlet in the heat exchange, thereby increasing the refrigerating capacity per unit mass of the refrigerant. The temperature of the gaseous refrigerant at the evaporator outlet rises after absorbing the heat of the condenser liquid, which can ensure that the gas inhaled by the compressor is completely gas, avoiding the risk of liquid hammer, and at the same time reducing the suction specific volume and lowering the power consumption of the compressor.

[0030] Referring to Figure 2 and Figure 3 , which is a schematic framework diagram of the defrosting process of the ice maker in the embodiment of the present application. As Figure 2 shown, during the defrosting process, in the defrosting state, the defrosting valve and the water inlet valve are opened. The high-temperature and high-pressure gaseous refrigerant formed by compressing the refrigerant in the compressor enters the evaporator through the defrosting valve and exchanges heat with the ice cubes on the ice-making plate to defrost the ice-making plate. At the same time, during the defrosting process, the water inlet valve is opened to let water in, which can not only accelerate the defrosting of the ice-making plate but also inject the water volume required for the next ice-making into the water tank to ensure continuous ice-making of the ice maker. During defrosting, the water level monitoring device detects the water level in the water tank in real time. When the water level in the water tank rises to the height of the overflow port, the water inlet valve is closed and the water pump is turned on. The water pump pumps the water in the water tank to the upper part of the ice-making plate to wash the ice-making plate, so that the ice cubes on the ice-making plate are completely separated from the ice-making plate, completing defrosting. Then the water pump and the defrosting valve are closed.

[0031] The control method of the ice maker provided by the embodiment of the present application includes steps such as controlling water inlet in response to the ice making signal, starting ice making by monitoring the water level, starting ice ejection based on the water level, and monitoring the temperature at the outlet of the evaporator to determine ice making or cyclic ice ejection. Among them, by real-time monitoring of the water level in the water tank and the temperature at the outlet of the evaporator, the ice making and ice ejection processes are accurately controlled, achieving the effects of improving ice making efficiency and ice cube quality, and ensuring the stable and reliable operation of the ice maker. This is because accurate water level and temperature monitoring can dynamically adjust the ice making and ice ejection processes according to the actual situation, avoiding problems such as incomplete ice ejection caused by the lack of accurate monitoring in traditional methods.

[0032] Referring to Figure 4 , it is a schematic flow chart of a control method of an ice maker disclosed by an embodiment of the present application. This control method of the ice maker is applied to an ice maker, which includes a controller, a compressor, a condenser, an ice ejection valve, an evaporator, an ice making plate, a water inlet valve, and a water tank. The ice ejection valve is installed between the compressor and the evaporator. As Figure 4 shown, the control method of the ice maker may include the following steps: S100, open the water inlet valve in response to the ice making control signal, and receive the water injection level of the water tank; S200, when the water injection level reaches the preset ice making water level, start ice making, and obtain the dynamic ice making water level of the water tank.

[0033] Specifically, when ice making is required, by powering on the ice maker or inputting an ice making start instruction on the intelligent control terminal, when the ice maker receives the ice making control signal, it opens the water inlet valve and real-time detects the water injection level in the water tank. When the water injection level in the water tank reaches the preset ice making water level, it starts to make ice, and during the ice making process, it real-time monitors the dynamic ice making water level in the water tank for real-time monitoring of the ice making process.

[0034] Among them, the ice making control signal can be generated by powering on the ice maker, or by a user inputting an ice making start instruction on the remote control device of the ice maker; it can also be generated when the user connects the intelligent terminal to the ice maker for communication and inputs an ice making start control instruction on the human-computer interaction module of the intelligent terminal.

[0035] A water level detection device is provided in the water tank, and the water level detection device is electrically connected to the controller, so that the water level detection device can real-time transmit the monitored water level information of the water tank to the controller, thereby realizing the ice making control and ice ejection control of the ice maker according to the water level change in the water tank. The water level monitoring device can be a float type water level sensor, which uses the principle of the float changing with the water level to convert the water level information into an electrical signal and transmit it to the controller. It can also use a pressure type water level sensor to indirectly measure the water level by detecting the pressure at the bottom of the water tank.

[0036] The water inlet valve usually adopts an electromagnetic valve. This kind of valve has high control precision and can quickly respond to control signals to achieve opening and closing. It is installed on the water inlet pipe of the sink and is connected to the controller through a signal wire. When receiving the ice-making control signal, the controller will send an electrical signal to the water inlet valve to open it.

[0037] In the embodiment of the present application, the ice maker includes an ice-making state and a defrosting state. In the ice-making state, the compressor starts to work, compresses the refrigerant into a high-temperature and high-pressure gas. The compressor is connected to the condenser and the evaporator through pipelines to form a refrigeration cycle system. The condenser plays a role in heat dissipation, cooling the high-temperature and high-pressure gas discharged from the compressor into a liquid state. Here, the condenser can be an air-cooled condenser, which accelerates air flow through a fan to take away heat, or a water-cooled condenser, which uses the cooling capacity of water for heat dissipation. The evaporator is the key component for ice-making. When the refrigerant evaporates in the evaporator, it absorbs the surrounding heat, reducing the surface temperature of the ice-making plate, thereby achieving ice-making.

[0038] In the embodiment of the present application, a fan is provided at the condenser. The condensation effect of the condenser is enhanced through the following steps, including: obtaining the current condensation temperature at the outlet of the condenser and comparing the current condensation temperature with a preset condensation temperature threshold; when the condensation temperature is greater than or equal to the preset condensation temperature threshold, turning on the fan.

[0039] During the ice-making process, the monitoring of the condenser outlet temperature and the control of the fan are added. When the condenser is an air-cooled condenser, after responding to the ice-making control signal to start ice-making, the current condensation temperature at the outlet of the condenser will be obtained and compared with the preset condensation temperature threshold. When the condensation temperature is greater than or equal to the preset condensation temperature threshold, the fan is turned on. Before generating the first defrost signal based on the first preset defrosting duration and starting the first defrosting, an ice-making stop signal will be generated, and the fan will be turned off within the preset conversion duration based on the ice-making stop signal.

[0040] By monitoring the condenser outlet temperature, the opening and closing of the fan are reasonably controlled. When the condensation temperature is too high, turning on the fan can accelerate the heat dissipation of the condenser, ensure the normal operation of the refrigeration system, and improve the ice-making efficiency. Turning off the fan before defrosting avoids unnecessary energy consumption and achieves the purpose of energy saving. Such a control strategy enables the ice maker to operate efficiently and stably under different working conditions.

[0041] S300, when the ice-making dynamic water level is less than or equal to the first preset water level threshold, generate a first defrost signal based on the first preset defrosting duration and start defrosting.

[0042] Specifically, during the ice-making process, continuously obtain the dynamic ice-making water level of the water tank. When the dynamic ice-making water level is less than or equal to the first preset water level threshold, it indicates that the water level in the current water tank has all frozen into ice cubes. At this time, it is necessary to start defrosting, generate a first defrosting signal based on the first preset defrosting duration, and start defrosting.

[0043] The defrosting operation mainly relies on the defrosting valve. The defrosting valve is installed between the compressor and the evaporator and is generally an electric ball valve, which can quickly cut off or conduct the flow direction of the refrigerant. When receiving the defrosting signal, the defrosting valve opens, changing the flow path of the refrigerant, heating the evaporator, and thus achieving defrosting.

[0044] S400, obtain the first temperature value at the outlet of the evaporator when the first preset defrosting duration ends, and compare the first temperature value with the first preset temperature threshold.

[0045] Specifically, by installing a first temperature value sensor at the outlet of the evaporator, during the defrosting process under the first preset defrosting duration, the first temperature value sensor continuously collects the first temperature value at the outlet of the evaporator and compares the first temperature value with the first preset temperature threshold.

[0046] Among them, the first preset temperature threshold is used to represent the temperature value at the outlet of the evaporator when defrosting is completed. That is, compare the first temperature value at the outlet of the evaporator during the defrosting process with the first preset temperature threshold to determine whether defrosting is completed, so as to ensure that no ice cubes remain on the ice-making plate, thus affecting the normal use of the ice maker.

[0047] Determining whether defrosting is completed by comparing the first temperature value with the first preset temperature threshold includes the following two steps: S401, when the first temperature value is greater than or equal to the first preset temperature threshold, generate an ice-making control signal and execute the step of starting ice-making in response to the ice-making control signal; S402, when the first temperature value threshold is less than the first preset temperature threshold, generate a defrosting signal based on the first temperature value and start defrosting until the temperature value at the outlet of the evaporator is greater than or equal to the first preset temperature threshold.

[0048] Specifically, when the first temperature value is greater than or equal to the first preset temperature threshold, it indicates that defrosting is completed, generate an ice-making control signal, and execute the step of starting ice-making in response to the ice-making control signal. When the first temperature value threshold is less than the first preset temperature threshold, generate a cyclic defrosting signal and start defrosting until the temperature value at the outlet of the evaporator is greater than or equal to the first preset temperature threshold. This can ensure thorough defrosting and improve the quality of ice cubes.

[0049] Among them, the first temperature value sensor can be a temperature monitoring device such as a thermistor or a thermocouple that can monitor temperature changes in real time and transmit the monitored data to the controller.

[0050] The first preset temperature threshold is illustrated by taking 7°C as an example. For example, Figure 5 As shown, after ice making is completed, defrosting is achieved by using the first defrosting signal, and the first temperature value collected at the evaporator outlet when the first defrosting duration ends is greater than the first preset temperature threshold. That is, in the figure, T2 represents the first temperature value at the evaporator outlet when the first defrosting duration ends, which is 7°C, meeting the condition for completing defrosting, completing defrosting, and entering the next round of ice making.

[0051] In an embodiment of the present application, an implementation manner of generating a defrosting signal based on the first temperature value and starting defrosting until the temperature value at the evaporator outlet is greater than or equal to the first preset temperature threshold includes: Comparing the first temperature value with a second preset temperature threshold. When the first temperature value is greater than or equal to the second preset temperature threshold, generating a second defrosting signal according to a first preset duration and starting defrosting; obtaining a second temperature value at the evaporator outlet when the first preset ice making duration ends, and comparing the second temperature value with the first preset temperature threshold; when the second temperature value is greater than or equal to the first preset temperature threshold, generating an ice making control signal and performing the step of starting ice making in response to the ice making control signal; when the second temperature is less than the first preset temperature threshold, generating a defrosting signal according to a third preset defrosting duration and starting defrosting; obtaining a third temperature value at the evaporator outlet when the third preset defrosting duration ends, and comparing the third temperature value with the first preset temperature threshold; when the third temperature threshold is greater than or equal to the first preset temperature threshold, generating an ice making control signal and performing the step of starting ice making in response to the ice making control signal; when the third temperature threshold is less than the first preset temperature threshold, performing defrosting for a first preset number of defrosting times according to the third preset defrosting duration; obtaining a fourth temperature value at the evaporator outlet when the defrosting for the first preset number of defrosting times is completed, and comparing the fourth temperature value with the first preset temperature threshold; if the fourth temperature value is greater than or equal to the first preset temperature threshold, generating an ice making control signal and performing the step of starting ice making in response to the ice making control signal; if the fourth temperature threshold is less than the first preset temperature threshold, generating a fault alarm signal and triggering an alarm.

[0052] Specifically, when the first temperature value is less than the first preset temperature threshold, the first temperature value is compared with the second preset temperature threshold. When the first temperature value is greater than or equal to the second preset temperature threshold, a second defrost signal is generated according to the first preset duration and defrosting is started. The second temperature value at the evaporator outlet at the end of the first preset ice duration is obtained, and then the second temperature value is compared with the first preset temperature threshold. If the second temperature value is greater than or equal to the first preset temperature threshold, an ice-making control signal is generated and ice-making is started; if the second temperature is less than the first preset temperature threshold, a defrost signal is generated according to the third preset defrost duration and defrosting is started. Subsequently, temperature comparisons and defrost operations will be performed multiple times until a fault alarm signal is generated when the temperature at the evaporator outlet reaches the first preset temperature threshold or the required temperature is not reached after a certain number of defrost operations are completed.

[0053] After the defrost duration corresponding to each defrost signal ends, the temperature value at the outlet of the evaporator is compared with the first preset temperature value, so as to determine whether defrosting is completed after the defrost duration corresponding to each defrost signal.

[0054] Taking the first preset temperature threshold as 7°C and the second preset temperature threshold as 5°C as an example, the defrost process 1 in the figure represents the defrosting process of the first preset defrost duration corresponding to the first defrost signal, that is, T2 represents that after the first preset defrost duration ends, the temperature at the evaporator outlet is greater than 5°C and less than 7°C, that is, greater than the second preset temperature threshold and less than the first preset temperature threshold, indicating that the current ice-making plate is at a low temperature but defrosting is not completed. The defrost process 2 represents the defrosting process of the first preset duration, that is, T3 represents the defrosting process of the first preset duration corresponding to the second defrost signal. The temperature at the evaporator outlet at the end of the first preset duration is as Figure 6 shown. In the figure, T3 is greater than 7°C, which indicates that defrosting is completed at this time, and the next round of ice-making can be entered. As Figure 7 and Figure 8 shown, the temperature T3 at the evaporator outlet at the end of the defrost process 2 in the figure is less than 7°C, that is, at the end of the third preset defrost time, the ice-making plate has not completed defrosting and the next round of ice-making cannot be carried out. The defrost process 3 in the figure represents the defrosting process of executing the third preset defrost duration. The first preset defrost times, taking 3 times as an example, when the temperature at the evaporator outlet is less than 7°C at the end of the third preset defrost duration, the defrosting process of executing the third preset defrost duration 3 times is carried out, and after the defrosting of the third defrost duration is completed 3 times, the temperature T4 at the evaporator outlet is obtained. Figure 7 In [the figure], T4 is greater than 7°C, which means that after the defrosting of the third preset defrost duration is carried out 3 times, the ice-making plate completes defrosting. Figure 8When T4 is less than 7°C, it is possible that each component in the ice maker malfunctions, generating a fault alarm signal and triggering an alarm to remind the user to repair the ice maker. For example, the first preset defrosting duration is 140 s, the first preset duration is 60 s, the third preset duration is 80 s, and the first preset defrosting frequency is 3 times. The above control method is to obtain T2 after 140 s of defrosting. If T2 is greater than 7°C, the next round of ice making is entered. If T2 is less than 7°C, 60 s of defrosting is performed to obtain T3. If T3 is greater than 7°C, the next round of ice making is entered. If T3 is less than 7°C, 80 s of defrosting is performed to obtain T4. If T4 is greater than 7°C, the next round of ice making is entered. If T4 is less than 7°C, 80 s of defrosting is performed 3 times, and the temperature at the outlet of the steam port is detected after each 80 s of defrosting to determine whether defrosting is completed. Only when the temperature at the outlet of the evaporator is greater than 7°C does it indicate that defrosting is completed. Otherwise, a fault alarm will be triggered after 3 times of 80 s of defrosting are completed.

[0055] There is another implementation method for the process of generating a defrosting signal according to the first temperature value and starting defrosting until the temperature value at the outlet of the evaporator is greater than or equal to the first preset temperature threshold, including: When the first temperature value is less than the second preset temperature threshold, a fifth defrosting signal is generated according to the second preset duration and defrosting is started, where the second preset duration is greater than the first preset duration; the fifth temperature value at the outlet of the evaporator at the end of the second preset duration is obtained, and the fifth temperature value is compared with the first preset temperature threshold; if the fifth temperature value is greater than or equal to the first preset temperature threshold, a ice making control signal is generated, and the step of starting ice making in response to the ice making control signal is executed; if the fifth temperature value is less than the first preset temperature threshold, defrosting is performed for the second preset defrosting frequency according to the second preset duration; the sixth temperature value at the outlet of the evaporator when the defrosting of the second preset defrosting frequency is completed is obtained, and the sixth temperature value is compared with the first preset temperature threshold; if the sixth temperature value is greater than or equal to the first preset temperature threshold, a ice making control signal is generated, and the step of starting ice making in response to the ice making control signal is executed; if the sixth temperature threshold is less than the first preset temperature threshold, a fault alarm signal is generated and the alarm is triggered.

[0056] Specifically, when the first temperature value is less than the second preset temperature threshold, different defrosting duration and frequency strategies are adopted. Specifically, a fifth defrosting signal is generated according to the second preset duration to initiate defrosting, where the second preset duration is greater than the first preset duration. The fifth temperature value at the evaporator outlet at the end of the second preset duration is obtained and compared with the first preset temperature threshold. If the fifth temperature value is greater than or equal to the first preset temperature threshold, an ice-making control signal is generated to initiate ice-making; if the fifth temperature value is less than the first preset temperature threshold, defrosting is performed for the second preset number of times according to the second preset duration. The sixth temperature value at the evaporator outlet when the defrosting for the second preset number of times is completed is obtained and compared with the first preset temperature threshold again. If the sixth temperature value is greater than or equal to the first preset temperature threshold, an ice-making control signal is generated to initiate ice-making; if the sixth temperature threshold is less than the first preset temperature threshold, a fault alarm signal is generated to trigger an alarm.

[0057] For the case where the first temperature value is less than the second preset temperature threshold, which is a lower temperature situation, longer defrosting duration and specific defrosting frequency are adopted to cope with the more difficult defrosting condition. By extending the defrosting time and increasing the defrosting frequency, the defrosting success rate is improved. If the preset temperature still cannot be reached after these operations, it indicates that there may be a relatively serious fault in the ice maker, and an alarm is timely triggered to remind the user to repair, so as to ensure the normal operation of the ice maker, improve the ice-making efficiency and ice quality.

[0058] Such as Figure 9As shown in the figure, taking the first preset temperature threshold as 7°C and the second preset temperature threshold as 5°C as an example, the defrosting process 1 in the figure represents the defrosting process under the first defrosting signal corresponding to the first preset defrosting duration. T2 in the figure represents that after the first preset defrosting duration ends, the first temperature value at the evaporator outlet is less than the second preset temperature threshold, that is, T2 is less than 5°C. t5 in the figure corresponds to the second preset duration, and T is the temperature value at the evaporator outlet at the end of the second preset duration. In the figure, T is greater than 7°C, indicating that defrosting is completed on the ice-making plate at the end of the second preset duration of defrosting. When T in the figure is less than 7°C, the second preset defrosting process is performed for the second preset number of defrosting times. For example, the first preset defrosting duration is 140s, the second preset number of defrosting times is 2 times, and the second preset duration is 180s. The above control method is to perform defrosting for 140s, and if T2 is less than 5°C, then perform defrosting for another 180s. After 180s of defrosting, obtain the fifth temperature value T at the evaporator outlet at this time. If the fifth temperature value T is greater than 7°C, then defrosting is completed. If the fifth temperature T is less than 7°C, then perform 2 times of 180s of defrosting, and during each of these 2 times of 180s of defrosting, the temperature at the evaporator outlet is judged at the end of each time. Only when the temperature is greater than 7°C, the next round of ice-making is performed. When the 2 times of 180s of defrosting are completed, if the sixth temperature T at the evaporator outlet is less than 7°C, it indicates that the ice maker may malfunction at this time, and an alarm signal is generated and the alarm is triggered to remind the user to repair the ice maker.

[0059] In the embodiments of the present application, after each defrosting is completed and before the next ice-making starts, by flushing the ice-making plate to completely defrost the ice on the ice-making plate, it can be achieved through the following steps: The ice maker further includes a flushing pipe, a water pump, and a drain valve, and the flushing and water-changing control steps are added. Before generating the ice-making control signal and executing the step of starting ice-making in response to the ice-making control signal, a flushing signal is generated and the water pump is turned on, and based on the flushing signal, the water pump is controlled to extract water from the water tank to flush the ice-making plate within a preset flushing duration. In addition, the current ice-making times are obtained and compared with the preset water-changing times threshold. When the current ice-making times reach the preset water-changing times threshold, the drain valve is opened.

[0060] Flushing the ice-making plate can clean the surface of the ice-making plate, remove impurities and residual ice, create good conditions for the next ice-making, and help improve the ice quality. Regularly changing water can ensure the cleanliness of the water quality in the water tank, prevent the accumulation of impurities in the water from affecting the ice-making effect and the service life of the ice maker. Through these additional control steps, the performance and reliability of the ice maker are further improved, providing a better ice-making experience for users.

[0061] It should be noted that: The methods and system embodiments provided in the above embodiments belong to the same concept, and the specific implementation process is detailed in the system embodiment, which will not be elaborated here.

[0062] Reference Figure 10 , which is a schematic structural diagram of a control device for an ice maker disclosed in an embodiment of the present application. As Figure 10 shown, the device includes: A signal response module for responding to an ice-making control signal to open a water inlet valve and receiving the water injection level of the water tank; An ice-making start module for starting ice-making when the water injection level reaches a preset ice-making level and obtaining the ice-making dynamic level of the water tank; A defrosting start module for generating a first defrosting signal based on a first preset defrosting duration and starting defrosting when the ice-making dynamic level is less than or equal to a first preset water level threshold; A numerical comparison module for obtaining a first temperature value at the outlet of the evaporator when the first preset defrosting duration ends and comparing the first temperature value with a first preset temperature threshold; A signal generation unit for generating an ice-making control signal when the first temperature value is greater than or equal to the first preset temperature threshold and performing the step of starting ice-making in response to the ice-making control signal; A defrosting adjustment unit for generating a defrosting signal based on the first temperature value and starting defrosting when the first temperature value threshold is less than the first preset temperature threshold until the temperature value at the outlet of the evaporator is greater than or equal to the first preset temperature threshold.

[0063] The ice-making start module starts ice-making when the water injection level reaches the preset ice-making level and obtains the ice-making dynamic level of the water tank. The first defrosting module generates a first defrosting signal based on the first preset defrosting duration and starts defrosting when the ice-making dynamic level is less than or equal to the first preset water level threshold. The first comparison module obtains the first temperature value at the outlet of the evaporator when the first preset defrosting duration ends and compares it with the first preset temperature threshold. Subsequent modules generate corresponding signals according to different temperature comparison results and control the ice maker to perform ice-making, defrosting or alarm operations respectively.

[0064] Through the collaborative work of each module, the automatic and intelligent control of the ice maker is realized. Each module is responsible for a specific function, makes judgments and decisions based on the real-time monitored data, and ensures the accuracy and efficiency of the ice-making and defrosting processes of the ice maker. Compared with the traditional control method, this modular design improves the stability and maintainability of the system, can timely detect and handle problems in the ice-making process, and ensures the reliable operation of the ice maker.
