Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ice maker control, in particular to a temperature control method, device, equipment and medium for an ice maker. BACKGROUND

[0002] Ice makers are widely used in modern life and industrial production, and the core function is to freeze water into ice cubes to meet the needs in different scenarios. Ice removal is a key link of the ice maker, which needs to adjust the evaporator temperature to make the ice layer melt and separate, and the control effect directly affects the ice removal efficiency and operation stability of the ice maker. If the temperature control of the ice removal link is not good, problems such as ice layer residue, long ice removal time or increased energy consumption may occur, which may affect the subsequent ice making quality and even shorten the service life of the equipment.

[0003] At present, the ice removal temperature control scheme of the mainstream ice maker has obvious defects. Before the ice removal link, the connection reliability of evaporator temperature detection and demand determination is insufficient, and the ice removal time is often improper due to inaccurate temperature state reflection; and in the ice removal execution link, there is a lack of temperature control logic adapted to the actual working condition, and the adjustment operation is difficult to promote the ice removal process, so that the ice removal effect is unstable and it is difficult to meet the demand of efficient and continuous operation of the ice maker.

[0010] Further, in some embodiments of the present application, when the heater ice-off mode is selected as the temperature control mode, the corresponding ice-off temperature regulation operation based on the temperature control mode is performed until the ice-off task is completed, comprising: generating a compressor stop instruction and delaying for a fourth preset time length to ensure that the compressor is completely stopped; starting an electric heater arranged on the evaporator and controlling the electric heater to heat at a preset power; monitoring the evaporator temperature in real time, and when it is monitored that the evaporator temperature reaches a second target defrosting temperature, controlling the electric heater to switch to a constant temperature control mode; After maintaining the constant temperature control mode for a third preset time length, the electric heater is turned off.

[0011] Further, in some embodiments of the present application, the control of the electric heater to heat at a preset power includes: In the initial heating stage, the electric heater is controlled to heat at a first power for rapid temperature rise; When the difference between the evaporator temperature and the second target defrosting temperature is less than a preset threshold, the electric heater is controlled to switch to a second power lower than the first power for fine temperature rise.

[0012] Further, in some embodiments of the present application, the temperature control mode further includes a cooperative control mode, and the corresponding defrosting temperature adjustment operation is performed based on the temperature control mode until the defrosting task is completed, including: controlling the refrigerant circuit to flow high-temperature refrigerant into the evaporator, and starting the electric heater arranged on the evaporator; According to the evaporator temperature monitored in real time, the flow rate of the high-temperature refrigerant and the heating power of the electric heater are dynamically adjusted; When the evaporator temperature reaches a third target defrosting temperature, the electric heater is preferentially turned off, and the remaining defrosting process is completed by the high-temperature refrigerant.

Finally, the adjustment is performed based on the mode until the ice release task is completed to form an execution closed loop and avoid the situation that the adjustment operation cannot be promoted to the completion of the ice release. Therefore, by detecting the evaporator temperature in real time to determine the ice release requirement, generating an ice release trigger signal and selecting a corresponding temperature control mode to perform an ice release temperature adjustment operation, the present application can improve the reliability of the ice release requirement determination and the adaptability of the ice release execution, ensure the stable and efficient completion of the ice release task, and thus improve the ice release effect and the operation stability of the ice maker, solving the problem of poor ice release effect in the existing ice maker ice release temperature control technology.

[0025] Figure 1 An application environment diagram of a temperature control method for an ice maker in an embodiment. Refer to Figure 1 The temperature control method for the ice maker is applied to a temperature control system of the ice maker. The temperature control system for the ice maker includes a terminal 110 and a server 120. The terminal 110 and the server 120 are connected through a network, the terminal 110 can be a desktop terminal or a mobile terminal, the mobile terminal can be at least one of a mobile phone, a tablet computer, a notebook computer, etc., and the terminal can also be an ice maker. The server 120 can be implemented by an independent server or a server cluster composed of multiple servers. The terminal 110 is configured to execute the above-mentioned temperature control method for the ice maker, which includes: detecting the evaporator temperature of the ice maker in real time, and determining whether the ice removal demand is met according to the evaporator temperature; when it is determined that the ice removal demand is met, generating a corresponding ice removal trigger signal; selecting a corresponding temperature control mode based on the ice removal trigger signal; and performing a corresponding ice removal temperature adjustment operation based on the temperature control mode until the ice removal task is completed.

[0026] Please refer to Figure 2 , Figure 2 is a flowchart of a temperature control method for an ice maker provided by an embodiment of the present application, and the embodiment mainly takes an example of the temperature control method for the ice maker being applied to an ice maker to illustrate, the ice maker specifically includes an evaporator, a compressor and an electric heater, and the temperature control method for the ice maker provided by an embodiment of the present application can specifically include the following steps: S1. Detecting the evaporator temperature of the ice maker in real time, and determining whether the ice removal demand is met according to the evaporator temperature; Specifically, for step S1, first, the real-time detection of the evaporator temperature is completed. In the running process of the ice maker, the temperature data of the evaporator is continuously collected through the temperature detection component (such as a temperature sensor) pre-installed on the surface or inside of the evaporator, the collection process is uninterrupted, and the dynamic change of the evaporator temperature can be ensured to be acquired in time, for example, the evaporator temperature is collected every 10 seconds during the ice making stage of the ice maker, and the temperature value is continuously recorded. The ice maker is pre-set with a temperature judgment standard for ice removal demand, which is determined according to the ice making capacity of the ice maker, the ice layer thickness requirement, etc., and the real-time collected evaporator temperature is compared with the standard. For example, if the evaporator temperature continuously below -10℃ and the ice layer thickness has affected the next round of ice making are set as the ice removal demand standard, when the evaporator temperature continuously maintains -12℃ for a certain state is detected in real time, it is determined that the ice removal demand is met; if the real-time temperature is -5℃ and the ice layer is thin and does not affect the subsequent ice making, it is determined that the ice removal demand is not met.

[0027] S2. When it is determined that the ice removal demand is met, a corresponding ice removal trigger signal is generated; Specifically, for step S2, the ice maker control unit confirms the ice-off demand determination result, receives the determination result that the ice-off demand is met, verifies the result, for example, confirms that the temperature detection component is not malfunctioning, the collected temperature data is not abnormal, and ensures that the determination result is accurate. After verification, the control unit immediately generates a signal (such as an electrical signal or a logical signal) for starting the ice-off process, which needs to be clearly directed to the subsequent temperature control mode selection link to ensure that the signal can be accurately received. For example, when it is confirmed that the ice-off demand is met, the control unit outputs a 24V electrical signal as an ice-off trigger signal to the module responsible for selecting the temperature control mode.

[0028] S3. Select the corresponding temperature control mode based on the ice-off trigger signal; Specifically, for step S3, the component responsible for temperature control mode selection (such as the mode selection module) receives the generated ice-off trigger signal and confirms that the signal is valid, including signal strength and format meeting the pre-set requirements. The ice maker pre-stores at least one temperature control mode for ice-off, such as a high-temperature medium warming mode or a heating element heating mode, and the mode selection module selects the most suitable one from the pre-set modes based on the current basic operating state of the ice maker, such as whether it is in a low-power mode or whether the compressor is working normally. For example, if the current compressor of the ice maker is in normal operating state without shutdown restrictions, select the temperature control mode using high-temperature refrigerant warming; if the ice maker is currently in a low-power state and needs to reduce energy consumption, select the temperature control mode using a low-power heating element.

[0029] S4. Perform corresponding ice-off temperature adjustment operations based on the temperature control mode until the ice-off task is completed; Specifically, for step S4, according to the selected temperature control mode, the corresponding temperature adjustment operation process (such as heating power, medium flow control method, etc.) of the mode is retrieved. For example, if the heating element heating mode is selected, the initial power of the heating element, the temperature rise rate, and the target temperature are retrieved; if the high-temperature refrigerant warming mode is selected, the refrigerant flow and the flow duration are retrieved. According to the retrieved operation rules, control the relevant components of the ice maker (such as heating elements, refrigerant valves, etc.) to perform operations and continuously adjust the evaporator temperature. For example, when the heating element heating mode is selected, the heating element is started and heated at the set power to gradually raise the evaporator temperature; when the high-temperature refrigerant warming mode is selected, the refrigerant valve is controlled to open to allow high-temperature refrigerant to flow into the evaporator to raise the evaporator temperature. While performing temperature adjustment operations, real-time monitoring of whether the ice layer has fallen off the evaporator is performed through visual sensors or indirect temperature judgment (such as ice layer melting when the evaporator temperature rises to a certain value), etc. When it is confirmed that the ice layer has completely fallen off and the ice-off task is completed, stop the temperature adjustment operation and the ice maker can switch back to the ice-making mode.

[0030] The embodiment can accurately monitor the evaporator temperature of the ice maker in real time to determine the ice release demand, start the ice release process by triggering a signal, select an appropriate temperature control mode to perform adjustment operation, and finally efficiently complete the ice release to ensure that the ice maker can stably and continuously perform ice making operation.

[0031] Further, in some embodiments, the step S1 of "real-time detecting the evaporator temperature of the ice maker and determining whether the ice release demand is met according to the evaporator temperature" can specifically include: S11. periodically collecting temperature sensing data of the evaporator of the ice maker; Specifically, for the step S11, a collection period is determined, and a fixed collection time interval (period) is pre-set according to the evaporator temperature change rate and the ice maker operation accuracy requirement, which needs to ensure that the dynamic change of the evaporator temperature can be captured in time, while avoiding excessive collection leading to resource waste. The temperature sensor installed at the key position of the evaporator (such as the surface of the evaporator coil and the ice layer contact area) continuously obtains temperature data according to the set period. For example, if the collection period is set to 8 seconds, the temperature sensor automatically records the current temperature value of the evaporator once every 8 seconds, such as the first collection value of -11℃, the second collection value of -10.8℃, and the third collection value of -11.2℃.

[0032] S12. performing smoothing filtering processing on the temperature sensing data to obtain the processed real-time temperature value of the evaporator; Specifically, for the step S12, the data fluctuation problem is identified: during the collection process of the temperature sensor, accidental deviation (noise) may occur in the single collection data due to environmental interference, such as the change of air flow inside the ice maker and the slight vibration of the sensor, for example, the evaporator originally stable at -10℃ suddenly jumps to -8.5℃, which is not the real temperature change. A pre-set filtering algorithm (such as moving average method or weighted average method) is used to calculate the temperature data collected continuously for multiple times to eliminate accidental fluctuations. For example, using the 3-time moving average method, the current collection value is added to the previous two collection values and then divided by 3, if the continuous three collection values are -10.2℃, -8.5℃ and -10.1℃, the processed data is (-10.2+(-8.5)+(-10.1)) / 3≈-9.6℃, which is closer to the real temperature of the evaporator; finally, the result of each filtering calculation is taken as the processed real-time temperature value of the evaporator.

[0033] S13. comparing the processed real-time temperature of the evaporator with the pre-set ice release triggering threshold to generate a comparison result; Specifically, for step S13, a deicing trigger threshold is determined, and a temperature critical value (deicing trigger threshold) for determining whether deicing is needed is pre-set according to the ice making specifications of the ice maker, such as ice layer thickness requirements and evaporator material heat dissipation characteristics, which needs to ensure that the ice layer has reached a sufficient thickness and has deicing conditions. For example, for a certain type of ice maker, the deicing trigger threshold is set to -9°C. The obtained processed evaporator real-time temperature value is compared with the pre-set deicing trigger threshold, and the size relationship between the two is determined. For example, if the processed real-time temperature is -9.5°C, a comparison result that the real-time temperature is lower than the deicing trigger threshold (-9°C) is generated; if the processed real-time temperature is -8.8°C, a comparison result that the real-time temperature is higher than the deicing trigger threshold (-9°C) is generated.

[0034] S14. If it is determined based on the comparison result that the evaporator real-time temperature continues to be lower than the deicing trigger threshold for a first pre-set duration, it is determined that the deicing requirement is met; otherwise, it is determined that the deicing requirement is not met. Specifically, for step S14, in order to avoid misjudgment caused by short-term temperature fluctuations, such as the evaporator temperature temporarily falling below the threshold and then rising immediately, a first pre-set duration is pre-set, which needs to ensure that the temperature below the threshold is stable, not accidental. For example, the first pre-set duration is set to 90 seconds. The comparison result of the processed evaporator real-time temperature and the deicing trigger threshold is continuously tracked, and the cumulative duration of the real-time temperature being continuously lower than the threshold is counted. If the cumulative duration reaches the first pre-set duration (for example, the temperature is continuously lower than -9°C for 90 seconds), it is determined that the deicing requirement is met; if the cumulative duration does not reach (for example, the temperature is only lower than the threshold for 40 seconds and then rises to -8.5°C), it is determined that the deicing requirement is not met.

[0035] The embodiment can eliminate temperature errors caused by accidental interference by periodically collecting temperature data and performing smoothing filtering, and ensure the accuracy of the evaporator temperature data; in combination with the judgment logic that the real-time temperature is continuously lower than the threshold for a first pre-set duration, misjudgment caused by short-term temperature fluctuations can be avoided, and finally the deicing requirement can be accurately judged, providing a basis for reliable start of the subsequent deicing process.

[0036] Further, in some embodiments, step S3 "selecting a corresponding temperature control mode based on the deicing trigger signal" can specifically include: S31. receiving the deicing trigger signal and obtaining the current running state of the ice maker; Specifically, for step S31, the control unit (e.g., the main controller) of the ice maker receives a trigger signal for starting the ice removal process, which needs to meet the preset signal format (e.g., electrical signal, logic signal) and intensity requirements to ensure that the signal is not disturbed and can be accurately identified. For example, the control unit receives an electrical signal with a duration of 2 seconds and a voltage of 12V, confirming that the signal is a valid ice removal trigger signal. The control unit collects and integrates the current operating parameters of the ice maker by interacting with the signals of various core components of the ice maker (e.g., the compressor, the power management module, and the working condition monitoring module), and determines the current operating state. The operating state includes but is not limited to: whether the compressor is in operation, whether there is a compressor shutdown protection instruction, whether the power management module is set to low-power mode, and whether there is an emergency shutdown warning, etc. For example, the control unit learns from the current operating state of the compressor that the compressor is currently in normal operation and the power management module has not triggered a low-power instruction, i.e., the compressor can continue to operate; if it is detected that the compressor has received a shutdown instruction or the power management module is in low-power mode, the current operating state requires the compressor to stop or be in low-power mode.

[0037] S32. If it is determined that the current operating state allows the compressor to continue to operate, the hot gas ice removal mode is selected as the temperature control mode; Specifically, for step S32, if the control unit determines based on the obtained operating state that the compressor currently has no shutdown limitation (e.g., no overheat protection, no low-power instruction, no fault shutdown signal) and that continuous operation will not affect the subsequent working conditions of the ice maker, the hot gas ice removal mode is determined as the temperature control mode currently to be adopted. For example, the ice maker is in a peak period of continuous ice making, and the user's demand is to quickly complete ice removal and then start the next round of ice making. At this time, the compressor is currently operating normally and has no shutdown requirement, so the hot gas ice removal mode is selected.

[0038] S33. If it is determined that the current operating state requires the compressor to stop or be in low-power state, the heater ice removal mode is selected as the temperature control mode; Specifically, for step S33, if the control unit determines based on the obtained operating state that there is a compressor shutdown instruction (e.g., the compressor has been continuously operating for more than a preset time and needs to rest, or there is a local fault that needs to be stopped for troubleshooting), or the power management module has started the low-power mode (e.g., energy-saving setting when the ice maker is not used at night), the heater ice removal mode is determined as the temperature control mode currently to be adopted. For example, the ice maker has completed the main ice making task for the day and enters a low-power standby state at night, in order to avoid excessive power consumption of the compressor running continuously, the heater ice removal mode is selected at this time.

[0039] The embodiment can realize accurate adaptation of the ice removal mode to the actual running state of the ice maker by receiving the ice removal trigger signal first, accurately obtaining the current running state of the ice maker, and then matching the corresponding ice removal mode according to the running state, so as to select an appropriate mode to ensure ice removal efficiency when the compressor can continue to run, and select a suitable mode to meet the working condition limit when the machine needs to be stopped or low power consumption, thereby ensuring that the ice removal process is reliable and meets the current working condition requirements.

[0040] Further, in some embodiments, as shown in FIG. 4, when the hot gas ice removal mode is selected as the temperature control mode, the step S4 of “performing the corresponding ice removal temperature adjustment operation based on the temperature control mode until the ice removal task is completed” can specifically include: Figure 3 S41. Control the switching valve in the refrigerant circuit of the ice maker to make the high-temperature refrigerant discharged by the compressor directly flow into the evaporator. Specifically, for step S41, in the normal ice making stage of the ice maker, the switching valve in the refrigerant circuit is in the default communication state, at this time, the high-temperature and high-pressure refrigerant discharged by the compressor will preferentially flow to the condenser (for heat dissipation and cooling), and after being processed by the condenser, it will become low-temperature refrigerant through the throttling device, and finally flow into the evaporator to realize ice making. After determining to use the hot gas ice removal mode, the control unit of the ice maker will send an action instruction to the switching valve in the refrigerant circuit, which needs to specify the target position of the switching valve (i.e. change the refrigerant flow path). After receiving the instruction, the internal valve core of the switching valve will rotate or displace, cutting off the flow path of the refrigerant to the condenser, and at the same time, the channel between the compressor outlet and the evaporator inlet is turned on. At this time, the high-temperature refrigerant (usually 40-60°C) continuously discharged by the compressor will directly enter the evaporator, and the temperature of the evaporator will be raised through the heat transfer of the high-temperature refrigerant. For example, after the control unit sends an instruction to switch the switching valve to the evaporator communication position, the switching valve completes the action within 0.5 seconds, and the 50°C high-temperature refrigerant discharged by the compressor no longer flows to the condenser, but directly enters the evaporator pipeline.

[0041] S42. Real-time monitoring of the evaporator temperature, when the evaporator temperature is monitored to rise to the first target ice removal temperature, enter the temperature maintenance stage; ​Specifically, for step S42, while the high-temperature refrigerant flows into the evaporator, the temperature sensor installed on the surface of the evaporator will start high-frequency temperature collection (such as collecting once per second), and the collected temperature data will be transmitted to the control unit in real time. According to the material characteristics of the evaporator, the ice layer thickness requirement, a temperature value that can ensure that the ice layer starts to melt and does not damage the evaporator is set as the first target ice removal temperature, for example, set to 5°C, which can quickly melt the ice layer and will not cause the evaporator to age due to too high temperature. The control unit continuously compares the real-time collected evaporator temperature with the first target ice removal temperature, and when it is monitored that the temperature values collected for three consecutive times all reach or exceed the first target ice removal temperature, for example, the collected values for three consecutive times are 5°C, 5.2°C and 5.1°C, it is determined that the temperature has met the ice layer melting requirement, and the ice maker officially enters the temperature maintenance stage from the temperature rising stage.

[0042] S43. In the temperature maintenance stage, the flow of high-temperature refrigerant is controlled to maintain the temperature of the evaporator within the first target ice removal temperature range for a second preset duration; Specifically, for step S43, in order to avoid the evaporator temperature being too high or too low, which will waste energy or cause incomplete melting of the ice layer, the first target ice removal temperature range (such as 4-6°C) is set; the control unit adjusts the opening degree of the switching valve (such as partially opening the switching valve) or controls the bypass valve in the refrigerant circuit to change the flow of high-temperature refrigerant flowing into the evaporator, thereby adjusting the temperature of the evaporator. The temperature sensor continuously monitors the temperature of the evaporator, and if the temperature exceeds 6°C, the control unit will reduce the opening degree of the switching valve (such as adjusting from full opening to 50% opening), reduce the flow of high-temperature refrigerant, and make the temperature drop; if the temperature is lower than 4°C, the opening degree of the switching valve will be increased (such as adjusting from 50% opening to 80% opening), the flow of refrigerant will be increased, and the temperature will rise, so that the temperature is always stable within the range of 4-6°C. After the temperature is stable within the target range, the control unit starts timing to ensure that the maintenance state lasts for a second preset duration, which is set according to the ice layer thickness, for example, when the ice layer thickness is 5mm, the second preset duration is set to 30 seconds, to ensure that the ice layer on the surface of the evaporator is completely melted and separated from the evaporator.

[0043] S44. After the second preset duration ends, switch the refrigerant circuit to the normal ice making cycle; Specifically, in step S44, after the control unit detects that the second preset duration (e.g., 30 seconds) has completely ended, it confirms that the de-icing process is complete and generates a refrigerant circuit reset command. Upon receiving the reset command, the switching valve returns to its initial position, reconnecting the direct channel between the compressor outlet and the evaporator, and restoring the connection between the compressor outlet and the condenser. At this time, the high-temperature refrigerant flows back to the condenser, and after heat dissipation and throttling, becomes low-temperature refrigerant (e.g., below -10℃), flowing back into the evaporator. The evaporator temperature begins to gradually decrease, and the ice maker returns to its normal ice-making cycle, preparing for the next round of ice making. For example, after the 30-second maintenance period ends, the switching valve resets within 0.3 seconds, the refrigerant re-enters the condenser to cool down, and after 1 minute, the evaporator temperature drops to -12℃, starting a new round of ice making.

[0044] This embodiment, through precise control of refrigerant circuit switching, temperature monitoring and maintenance, can not only use high-temperature refrigerant to quickly raise the evaporator temperature to achieve de-icing, but also ensure that the temperature is stable within a reasonable range through flow regulation, avoiding energy waste or incomplete de-icing; at the same time, it can quickly switch back to the normal ice-making cycle after de-icing, effectively improving the overall operating efficiency and de-icing reliability of the ice maker.

[0045] Furthermore, in some embodiments, such as Figure 4 As shown, when the heater de-icing mode is selected as the temperature control mode, step S4, "execute the corresponding de-icing temperature adjustment operation based on the temperature control mode until the de-icing task is completed," can specifically include: S45. Generate a compressor stop command and delay for a fourth preset time to ensure the compressor stops completely; Specifically, for step S45, when it is determined to use the heater defrosting mode, since the compressor continues to work during the operation of the heater, it can cause the refrigerant circuit to be in disorder or the equipment to fail, therefore, the compressor needs to be stopped first. The control unit of the ice maker will first generate a clear compressor stop command, which needs to include the format of the stop signal (such as a low-level signal) and the execution priority (to ensure that the compressor responds to the stop first). The control unit transmits the stop command to the driving module of the compressor, and after the driving module receives the command, it cuts off the power input of the compressor, such as disconnecting the power supply circuit of the compressor motor, so that the compressor gradually stops running. Considering that there is inertia from the running state of the compressor to the complete stop, such as the gradual deceleration of the motor rotor to a standstill, a fourth preset time period is set in advance, for example, 30 seconds, which needs to cover the entire process from high-speed operation of the compressor to complete stop. The control unit starts timing immediately after sending the stop command, and before the fourth preset time period ends, the heater is not started to ensure that the compressor has completely stopped, such as by detecting the speed signal of the compressor to confirm that the speed has dropped to 0 before entering the next step. For example, after the control unit sends the stop command, it starts a 30-second countdown, and continuously monitors the speed of the compressor during the 30 seconds. When the countdown is over and the speed is 0, it is determined that the compressor has completely stopped.

[0046] S46. Start the electric heater arranged on the evaporator and control the electric heater to heat at a preset power; Specifically, for step S46, in the non-defrosting stage of the ice maker, the electric heater is in a power-off closed state to ensure that it does not affect normal ice making. When the fourth preset time period ends, the control unit confirms that the compressor has completely stopped, and sends a start command to the electric heater on the evaporator, and at the same time, the power supply circuit of the heater is turned on. According to the thickness of the ice layer on the evaporator, the heat resistance of the material, and other parameters, a preset power that can quickly raise the temperature without damaging the evaporator is set in advance, for example, 600W, which can make the temperature of the evaporator rise smoothly at a rate of 2℃ / min. The control unit adjusts the current or voltage in the power supply circuit of the heater to ensure that the heater always operates at the preset power. For example, after the electric heater is started, the control unit monitors the working current of the heater through the current sensor. If the current is lower than the current value corresponding to the preset power, such as 2.7A for 600W, the supply voltage is increased to restore the current to 2.7A, maintaining the heating power of 600W.

[0047] S47. Real-time monitoring of the temperature of the evaporator, when the temperature of the evaporator reaches the second target defrosting temperature, the control of the electric heater is switched to the constant temperature control mode; Specifically, for step S47, the temperature sensor installed on the surface of the evaporator starts to collect temperature data at a high frequency (e.g., once every 2 seconds) while the electric heater is started, and the data is transmitted to the control unit in real time. According to the temperature required for ice layer melting and the safe temperature range of the evaporator, a second target ice-melting temperature is set in advance, for example, 7°C, which can ensure rapid melting of the ice layer and prevent the metal parts of the evaporator from deforming due to excessive temperature. The control unit continuously compares the real-time collected temperature of the evaporator with the second target ice-melting temperature. When the temperature values collected continuously for two times both reach or exceed the second target ice-melting temperature, for example, 7°C and 7.1°C, it is determined that the temperature has met the requirements for ice layer melting. At this time, the control unit sends a constant temperature control instruction to the electric heater, switches the heater from the constant power heating mode to the constant temperature control mode, and adjusts the heating power in real time (e.g., reduces to 200W) to avoid continuous temperature rise of the evaporator. For example, after switching to the constant temperature mode, if the temperature rises to 7.5°C, the power is reduced to 180W; if the temperature drops to 6.8°C, the power is increased to 220W, to ensure that the temperature is stable around 7°C.

[0048] S48. maintaining the third preset time length in the constant temperature control mode, and turning off the electric heater; Specifically, for step S48, in order to ensure that the ice layer on the surface of the evaporator is completely melted and separated from the evaporator, and to avoid the residual ice layer affecting the next round of ice making, a third preset time length is set in advance, for example, 45 seconds, which can cover the complete melting process of the ice layer with a thickness of 5mm. The control unit starts counting when switching to the constant temperature control mode, and starts accumulating the constant temperature duration. When the counting reaches the third preset time length (e.g., 45 seconds), the control unit determines that the ice layer has been completely melted, and immediately sends a shutdown instruction to the electric heater to cut off the power supply circuit of the heater, so that the heater stops working, and the whole ice-melting temperature adjustment operation is completed. For example, after 45 seconds of counting, the control unit disconnects the power supply of the heater, the power of the heater is reduced to 0, and the heating is stopped.

[0049] The embodiment ensures that the compressor is completely stopped before the heater is started, avoiding equipment operation conflicts; the preset power is used for rapid heating, and the constant temperature control is switched after reaching the standard, which can efficiently melt ice and protect the evaporator; finally, the constant temperature is maintained to ensure that the ice layer is completely separated, and the safety, efficiency and complete ice-melting of the heater in the ice-melting mode are realized.

[0050] Further, in some embodiments, step S46 "controlling the electric heater to heat at a preset power" can specifically include: controlling the electric heater to rapidly heat at a first power in an initial heating stage; when the difference between the temperature of the evaporator and the second target ice-melting temperature is less than a preset threshold, controlling the electric heater to switch to a second power lower than the first power for fine heating.

[0051] In a specific embodiment, for step S46, when the evaporator needs to be heated by the electric heater to achieve defrosting, and the electric heater is just started, the initial heating stage is directly entered. The core goal of this stage is to quickly narrow the gap between the evaporator temperature and the second target defrosting temperature, and reduce the overall defrosting time. The value of the first power needs to be set in combination with the initial temperature of the evaporator, usually the evaporator temperature is low when defrosting is started, such as -12°C to -8°C, the initial thickness of the ice layer is, for example, 5mm to 8mm, and the rated power of the electric heater is comprehensively set to meet the requirements of rapid temperature rise and not to damage the equipment, which is not only higher than the power in the subsequent fine heating stage, but also avoids overloading the electric heater or local overheating of the evaporator due to too high power. The control unit of the ice maker sends a first power operation instruction to the electric heater, adjusts the current or voltage of the power supply loop of the electric heater, and makes the electric heater work stably at the first power. For example, if the initial temperature of the evaporator is -10°C, the second target defrosting temperature is 6°C, and the ice layer thickness is 6mm, the first power is set to 750W; after the control unit sends the instruction, the electric heater continues to heat at a power of 750W, at this time the evaporator temperature rises at a rate of about 2.5°C / min, quickly approaching the target temperature. During the process of heating the electric heater at the first power, the temperature sensor on the surface of the evaporator continuously collects real-time temperature (for example, 1 collection per second) and transmits the data to the control unit; the control unit calculates the difference between the second target defrosting temperature and the real-time temperature of the evaporator in real time to determine whether the temperature is close to the target value. The preset threshold needs to be set according to the temperature control accuracy requirement, usually 1°C to 3°C, and a too large threshold value will cause the switching opportunity to be too early, and the temperature overshoot may still occur; a too small threshold value will prolong the high-power heating time and waste energy. For example, if the second target defrosting temperature is 6°C, the preset threshold is set to 2°C. When the control unit monitors that the temperature difference is less than the preset threshold, for example, the real-time temperature of the evaporator rises to 4°C, the difference is 6°C-4°C=2°C, and the threshold is reached, immediately send a power switching instruction to the electric heater, reduce the running power from the first power (such as 750W) to the second power, and the second power needs to be lower than the first power, such as 280W; after the electric heater switches the power, it rises at a lower rate (such as 0.6°C / min), slowly approaches the second target defrosting temperature, and avoids overshooting the target value due to rapid temperature rise (i.e., temperature overshoot). For example, after switching to 280W, the evaporator temperature gradually rises from 4°C to 6°C, and the temperature fluctuation is not more than ±0.5°C throughout the process, achieving accurate temperature control.

[0052] In this embodiment, by using segmented heating control, the gap between the evaporator and the target defrosting temperature can be quickly narrowed, the defrosting efficiency can be improved, and the balance between efficiency and accuracy during the heating process of the electric heater can be achieved.

[0053] Further, in some embodiments, for example,Figure 6 As shown, the temperature control mode further includes a cooperative control mode, then step S4 "performing corresponding defrosting temperature adjustment operation based on the temperature control mode until completing the defrosting task" can specifically include: S401. Simultaneously control the refrigerant circuit to flow high-temperature refrigerant into the evaporator, and start the electric heater arranged on the evaporator; Specifically, for step S401, when it is determined to use the cooperative control mode for defrosting, both the refrigerant circuit and the electric heater need to be activated to realize the superposition of double heat sources to accelerate defrosting. The control unit of the ice maker sends an action instruction to the switching valve in the refrigerant circuit to cut off the flow path of the refrigerant to the condenser, and to open the channel between the outlet of the compressor and the inlet of the evaporator, so that the high-temperature refrigerant (usually 40-60℃) discharged by the compressor directly flows into the evaporator to raise the temperature of the evaporator through heat transfer of the refrigerant. For example, the switching valve completes the action within 0.4 seconds, and the high-temperature refrigerant at 55℃ starts to continuously enter the evaporator pipeline. At the same time of controlling the refrigerant circuit, the control unit sends a start instruction to the electric heater installed on the evaporator to turn on the power supply circuit of the heater, so that the heater starts to work immediately and directly heats the surface of the evaporator through electric heating conversion. For example, the heater starts to run at a preset initial power (such as 500W) immediately after starting, and works together with the high-temperature refrigerant on the evaporator.

[0054] S402. According to the real-time monitored evaporator temperature, dynamically adjusting the flow of high-temperature refrigerant and the heating power of the electric heater; Specifically, for step S402, after the high-temperature refrigerant flows in and the electric heater is started, the temperature sensor on the surface of the evaporator continuously collects the real-time temperature of the evaporator at a high frequency (such as 2 times per second) and transmits the data to the control unit in real time to ensure timely capture of the temperature change trend. The control unit has built-in temperature regulation rules. If the real-time temperature is lower than 70% of the third target ice melting temperature (for example, if the third target ice melting temperature is 8°C, it is lower than 5.6°C), it is determined that the heating effect needs to be enhanced; if the real-time temperature is between 70% and 90% of the third target ice melting temperature (for example, between 5.6°C and 7.2°C), it is determined that the medium heating intensity needs to be maintained; if the real-time temperature is higher than 90% of the third target ice melting temperature (for example, higher than 7.2°C), it is determined that the heating intensity needs to be reduced to avoid temperature overshoot. According to the above logic, the control unit sends adjustment instructions to the switching valve and the electric heater respectively: by changing the opening degree of the switching valve, such as increasing the opening degree from 80% to 100% to increase the flow or decreasing the opening degree from 80% to 50% to decrease the flow, the control unit controls the amount of high-temperature refrigerant flowing into the evaporator, thereby adjusting the heating intensity on the refrigerant side. For example, when the real-time temperature is 5°C (lower than 5.6°C), the control unit increases the opening degree of the switching valve from 80% to 100% to increase the amount of high-temperature refrigerant flowing in. By changing the current or voltage of the electric heater power supply circuit, such as increasing the power from 500W to 600W to enhance the power or decreasing the power from 500W to 300W to reduce the power, the control unit adjusts the heating intensity of the heater. For example, when the real-time temperature is 7.3°C (higher than 7.2°C), the control unit reduces the heater power from 500W to 300W to weaken the heating effect.

[0055] S403. When the temperature of the evaporator reaches the third target ice melting temperature, the electric heater is turned off first, and the remaining ice melting process is completed by the high-temperature refrigerant; Specifically, for step S403, the third target ice melting temperature needs to be set in combination with the characteristics of dual heat source cooperative heating, both to ensure that the ice layer has been mostly melted and to reserve space for subsequent refrigerant-only finishing, such as being set to 8°C, at which temperature the ice layer has softened and only a small amount of heat is needed to completely shed. The control unit continuously compares the real-time temperature with the third target ice melting temperature. When the temperature values collected for 3 consecutive times all reach or exceed the third target ice melting temperature (for example, the consecutive collected values are 8°C, 8.1°C, and 8.2°C), it is determined that the temperature has met the standard, and an immediate shutdown instruction is sent to the electric heater to cut off its power supply circuit, so that the heater stops working. After the heater is turned off, the control unit maintains the current state of the refrigerant circuit, allowing the high-temperature refrigerant to continue flowing into the evaporator, and through the continuous heating of the refrigerant, the temperature of the evaporator is stabilized at about 8°C, until the small amount of ice layer remaining on the surface of the evaporator is completely melted and shed (for example, for 15 seconds). For example, after the heater is turned off, the switching valve maintains an opening degree of 50%, and the high-temperature refrigerant continues to flow in. After 15 seconds, the visual sensor confirms that the ice layer has completely shed, and the ice melting is completed.

[0056] The embodiment can quickly raise the temperature of the evaporator through the cooperative heating of the refrigerant and the heater, greatly shorten the ice removal time, dynamically adjust the heat source intensity to avoid temperature overshoot, and preferentially turn off the heater after reaching the standard and only use the refrigerant to finish, thereby ensuring the ice removal efficiency and thoroughness, reducing unnecessary energy consumption, and realizing the dual effects of high efficiency and energy saving.

[0057] To sum up, the temperature control method for an ice maker provided by the embodiment can dynamically reflect the real temperature of the evaporator by detecting the evaporator temperature in real time and judging the ice removal demand, thereby avoiding the problem of misjudgment of the ice removal demand in the prior art and improving the reliability of demand judgment. When the ice removal demand is met, an ice removal trigger signal is generated to ensure accurate transmission of the ice removal start instruction and avoid improper start. Then, a corresponding temperature control mode is selected based on the ice removal trigger signal to solve the limitation of the lack of adaptive logic and the dependence on fixed adjustment mode in the ice removal execution stage of the prior art, so that the temperature control is more targeted. Finally, adjustment is performed based on the mode until the ice removal task is completed to form an execution closed loop and avoid the situation that the adjustment operation cannot be promoted to the completion of the ice removal. Thus, the embodiment can improve the reliability of ice removal demand judgment and the adaptability of ice removal execution by detecting the evaporator temperature in real time to judge the ice removal demand, generating an ice removal trigger signal, and selecting a corresponding temperature control mode to perform an ice removal temperature adjustment operation, thereby ensuring stable and efficient completion of the ice removal task and improving the ice removal effect and the operation stability of the ice maker, and solving the problem of poor ice removal effect in the ice removal temperature control technology of the existing ice maker.

[0060] Further, in some embodiments, the detection module 201 is specifically configured to: periodically collect temperature sensing data of the evaporator of the ice maker; smoothly filter the temperature sensing data to obtain a processed real-time evaporator temperature value; compare the processed real-time evaporator temperature with a preset ice-off triggering threshold to generate a comparison result; if it is determined based on the comparison result that the real-time evaporator temperature continuously falls below the ice-off triggering threshold for a first preset time length, it is determined that the ice-off requirement is met; otherwise, it is determined that the ice-off requirement is not met.

[0061] Further, in some embodiments, the selection module 203 is specifically configured to: receive the ice-off triggering signal and obtain a current running state of the ice maker; if it is determined that the current running state allows the compressor to continuously run, the hot gas ice-off mode is selected as the temperature control mode; if it is determined that the current running state requires the compressor to stop or be in a low-power consumption state, the heater ice-off mode is selected as the temperature control mode.

[0062] Further, in some embodiments, when the hot gas ice-off mode is selected as the temperature control mode, the adjustment module 204 is specifically configured to: control a switching valve in the refrigerant circuit of the ice maker to make the high-temperature refrigerant discharged by the compressor directly flow into the evaporator; monitor the evaporator temperature in real time, and when the evaporator temperature is monitored to rise to a first target ice-off temperature, enter a temperature maintenance stage; in the temperature maintenance stage, control the flow of the high-temperature refrigerant to maintain the evaporator temperature within a first target ice-off temperature range for a second preset time length; after the second preset time length ends, switch the refrigerant circuit to a normal ice-making cycle.

[0064] Furthermore, in some embodiments, controlling the electric heater to heat at a preset power includes: During the initial heating phase, the electric heater is controlled to rapidly heat up at a first power level; When the difference between the evaporator temperature and the second target de-icing temperature is less than a preset threshold, the electric heater is controlled to switch to a second power lower than the first power for precise heating.

[0065] Furthermore, in some embodiments, the temperature control mode further includes a cooperative control mode, in which the adjustment module 204 is specifically used to include: At the same time, the refrigerant circuit is controlled to allow high-temperature refrigerant to flow into the evaporator, and the electric heater installed on the evaporator is activated; Based on the real-time monitored evaporator temperature, the flow rate of the high-temperature refrigerant and the heating power of the electric heater are dynamically adjusted. When the evaporator temperature reaches the third target de-icing temperature, the electric heater is shut off first, and the remaining de-icing process is completed using high-temperature refrigerant.
