Description

Technical Field

[0001] This application belongs to the field of smart home appliance technology, specifically relating to an antifreeze treatment method, device, equipment, and computer storage medium. Background Technology

[0002] With the development of science and technology, energy conservation and environmental protection have gradually become hot topics. Therefore, while meeting their own usage needs, most users prefer to choose smart home appliances that are green, energy-saving, and low-energy.

[0003] Among them, smart home appliances equipped with air source heat pump units can meet the requirements of green energy saving and low energy consumption. In existing technologies, air source heat pump units are usually used to provide users with heating in winter and cooling in summer. The heat pump unit can exchange heat with the circulating water in the house and then release and absorb heat between the indoor and outdoor units through a water pump, thereby achieving heating and cooling effects.

[0004] However, low-temperature air source heat pumps are susceptible to freezing of the water-side heat exchanger and cracking of the water pump when the unit is not in use during winter or during cooling and defrosting. Currently, most low-temperature air source heat pumps use plate heat exchangers as the water-side heat exchanger. The single-layer channels of the plate heat exchanger are narrow, and freezing can cause the plates to deform or even crack, thus preventing the entire heat pump unit from operating normally. In addition, during cooling or defrosting, the water-side heat exchanger is in a low-pressure area, and the refrigerant evaporation temperature is too low, which can also cause the plate heat exchanger to freeze and crack.

Detailed Implementation

[0084] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0086] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0087] With the development of science and technology, energy conservation and environmental protection have gradually become hot topics. Therefore, while meeting their own usage needs, most users prefer to choose smart home appliances that are green, energy-saving, and low-energy.

[0088] Among them, smart home appliances equipped with air source heat pump units can meet the requirements of green energy saving and low energy consumption. In existing technologies, air source heat pump units are usually used to provide users with heating in winter and cooling in summer. The heat pump unit can exchange heat with the circulating water in the house and then release and absorb heat between the indoor and outdoor units through a water pump, thereby achieving heating and cooling effects.

[0089] However, if the unit is not started during winter and the water pump is not circulating after installation, the system may freeze and crack. Common freezing and cracking problems include water pump freezing and cracking of the water-side heat exchanger. In particular, most low-temperature air source heat pumps now use plate heat exchangers as the water-side heat exchanger. The single-layer channels of the plate heat exchanger are narrow, and freezing can cause the plates to deform or even crack, thus preventing the entire heat pump unit from working properly. In addition, during the defrosting process, because the water-side heat exchanger is in a low-pressure area, the refrigerant evaporation temperature is too low, which can also cause the plate heat exchanger to freeze and crack.

[0090] To address the above problems, this application provides an antifreeze treatment method.

[0091] First, the implementation scenarios involved in this application will be explained.

[0092] With the continuous development of science and technology, smart home appliances require increasingly diverse operating environments. It's not enough to simply consider their operation at room temperature; they also need to be able to function normally in low-temperature environments. For example, the smart home appliance described in this application could be a water heater equipped with multiple temperature and pressure sensors.

[0093] Smart home appliances can use temperature and pressure sensors to obtain the ambient temperature and the evaporation temperature of the unit, thereby determining whether the smart home appliance is in anti-freeze mode.

[0094] The antifreeze treatment method provided in this application acquires the ambient temperature, the unit's operating frequency, and the evaporation temperature, and then determines the appropriate values ​​based on the acquired temperature and frequency information. Depending on the determination results, auxiliary heating or unit frequency reduction can be used to achieve the antifreeze effect. This allows for the use of different methods to dynamically balance the unit's cooling load by matching the unit's real-time heating capacity, thereby controlling the compressor frequency. This method solves the problem of system freezing and cracking in low-temperature environments, ensuring the normal operation of the unit, further improving the efficiency of smart home appliances, and enhancing the user experience.

[0095] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0096] Figure 1 The flow chart of the antifreeze treatment method provided in the embodiments of this application Figure 1 The execution entity in this embodiment can be, for example, the processor of a smart home appliance. Figure 1 As shown, the antifreeze treatment method provided in this embodiment includes:

[0097] S101: Obtain the operating parameters of the smart home appliance, including the operating frequency and the determination temperature.

[0098] Among them, the operating frequency is the unit operating frequency of the smart home appliance, and the judgment temperature is used to determine whether the smart home appliance has entered the anti-freeze mode. There is a correlation between the operating frequency and the judgment temperature.

[0099] Understandably, operating frequency is part of the operating parameter information of smart home appliances; the judgment temperature can be multiple detection temperatures, and different judgment temperatures are used for judgment according to different operating environments.

[0100] For example, the heat pump unit installed in smart home appliances can detect compressor frequency, ambient temperature, and refrigerant-side pressure in the water-refrigerant heat exchanger. Therefore, based on the compressor frequency obtained by the heat pump unit, the operating frequency of the smart home appliance can be determined; based on the ambient temperature obtained by the heat pump unit through a temperature sensor, the set temperature of the smart home appliance can be determined; and based on the refrigerant-side pressure in the water-refrigerant heat exchanger obtained by the heat pump unit through a pressure sensor, thermodynamic calculations can be performed to obtain the refrigerant evaporation temperature, which can also be used to determine the set temperature of the smart home appliance.

[0101] S102: Determine the operating status of the smart home appliance based on the operating frequency, wherein the operating status is used to indicate whether the smart home appliance is currently running.

[0102] The operating frequency changes with the working state of smart home appliances, and different operating frequencies correspond to different working states of smart home appliances. Therefore, based on the current operating frequency of a smart home appliance, and obtaining a specific frequency value, one can intuitively reflect whether the smart home appliance is currently running, thereby determining whether the smart home appliance is currently running or not.

[0103] For example, when the compressor frequency is 0Hz, it indicates that the heat pump unit is not running, and the heat pump unit of the smart home appliance is in an inactive state; when the compressor frequency is 40Hz, it indicates that the heat pump unit is running, and the heat pump unit of the smart home appliance is in an active state.

[0104] S103: Based on the working state and the determined temperature, determine the anti-freeze mode of the smart home appliance, and control the smart home appliance to operate in the anti-freeze mode.

[0105] Among them, the anti-freeze mode refers to the working mode of smart home appliances to prevent the system from freezing and cracking under different working conditions.

[0106] The reasons for system freezing and cracking of smart home appliances vary depending on their operating state. For example, when the heat pump unit of a smart home appliance is not running, the water pump may freeze and crack because it is not circulating. When the heat pump unit of a smart home appliance is running, the water-side heat exchanger may freeze and crack during the cooling or defrosting process because it is in a low-pressure zone and the refrigerant evaporation temperature is too low.

[0107] In this step, different judgment temperatures can be selected to determine whether to enter the anti-freeze mode for different working states of smart home appliances, and the anti-freeze mode corresponding to the current working state can be determined, thereby controlling the smart home appliance to run the anti-freeze mode corresponding to the current working state.

[0108] For example, when the heat pump unit of a smart home appliance is not running, it can acquire the ambient temperature and use it as the determination temperature to decide whether to run the anti-freeze mode, and then control the smart home appliance to execute the determined result. When the heat pump unit of the smart home appliance is running, it can acquire the evaporation temperature at the water-side heat exchanger and use this evaporation temperature as the determination temperature to decide whether to run the anti-freeze mode, and then control the smart home appliance to execute the determined result.

[0109] Understandably, when the heat pump unit of a smart home appliance is not running, the anti-freeze mode is set to address the issue of water pump freezing and cracking caused by external environmental factors; when the heat pump unit of a smart home appliance is running, the anti-freeze mode is set to address the issue of water-side heat exchanger freezing and cracking caused by the cooling function of the water-side heat exchanger.

[0110] The anti-freeze treatment method provided in this embodiment acquires the operating frequency and determines the temperature, and then judges the acquired temperature and frequency information. Based on different judgment results, it determines the corresponding anti-freeze mode for the smart home appliance and enables the smart home appliance to operate in that anti-freeze mode. This method solves the defect of system freezing and cracking that occurs in low-temperature environments, thereby ensuring the normal operation of the unit and improving the user experience.

[0111] Figure 2 The flow chart of the antifreeze treatment method provided in the embodiments of this application Figure 2 .like Figure 2 As shown, in this embodiment... Figure 1 Based on the embodiments, the antifreeze treatment method is described in detail. The antifreeze treatment method shown in this embodiment includes:

[0112] S201: Obtain the operating parameters of the smart home appliance, including the operating frequency and the determination temperature.

[0113] Step S201 is similar to step S101 above, and will not be repeated here.

[0114] S202: Determine whether the operating frequency is greater than the preset operating frequency; if yes, proceed to step S213; if no, proceed to step S203.

[0115] The preset operating frequency refers to the frequency at which the smart home appliance is not in operation, such as 0Hz.

[0116] The purpose of this step, which determines whether the current operating frequency of the smart home appliance is greater than the preset operating frequency, is to determine the operating status of the smart home appliance.

[0117] If the current operating frequency of the smart home appliance is greater than the preset operating frequency, it indicates that the smart home appliance is running. At this time, the working state of the smart home appliance is determined as the second working state.

[0118] If the current operating frequency of the smart home appliance is not greater than the preset operating frequency, it indicates that the operating frequency is equal to the preset operating frequency, meaning that the smart home appliance is not running. In this case, the working state of the smart home appliance not running is determined as a working state.

[0119] Understandably, the operating frequency of smart home appliances can only be greater than or equal to the preset operating frequency. When the operating frequency of the smart home appliance is equal to the preset operating frequency, the smart home appliance is in the first operating state; when the operating frequency of the smart home appliance is greater than the preset operating frequency, the smart home appliance is in the second operating state.

[0120] For example, if the compressor frequency of the heat pump unit is 0Hz, which is equal to the preset operating frequency of 0Hz, then it can be determined that the heat pump unit is not running, and the smart home appliance will be in an inactive state. If the compressor frequency of the heat pump unit is 40Hz, which is greater than 0Hz, then it can be determined that the heat pump unit is running, and the smart home appliance will be in an active state.

[0121] S203: Determine the working state of the smart home appliance as a first working state, the first working state being used to indicate that the smart home appliance is not running.

[0122] S204: Determine whether the ambient temperature is greater than the first preset temperature; if yes, proceed to step S205; if no, proceed to step S206.

[0123] The ambient temperature refers to the external temperature of the smart home appliance. The first preset temperature is used to determine whether the water pump system of the smart home appliance is freezing; for example, the first preset temperature can be 3°C.

[0124] The purpose of determining whether the ambient temperature is higher than the first preset temperature is to determine whether the current smart home appliance needs to activate the antifreeze mode.

[0125] If the ambient temperature is higher than the first preset temperature, it indicates that there is no possibility of the smart home appliance freezing under the current environment. At this time, it is determined that the smart home appliance does not need to start the anti-freeze mode. Therefore, the current working mode of the smart home appliance remains unchanged and continues to operate in the current working mode.

[0126] If the ambient temperature is not higher than the first preset temperature, it indicates that the smart home appliance may freeze under the current conditions. In this case, it is determined that the smart home appliance needs to activate the anti-freeze mode, and the current working mode of the smart home appliance is set as the first anti-freeze mode. The first anti-freeze mode is used to instruct the smart home appliance to perform auxiliary heating; by providing auxiliary heating to the smart home appliance system, the anti-freeze effect is achieved.

[0127] Understandably, when smart home appliances are not running, the main factor affecting their activation of anti-freeze mode is the ambient temperature. For example, water pump systems may freeze below 0°C.

[0128] For example, if a smart home appliance detects an ambient temperature of 10℃ (10℃ > 3℃), then in an environment of 10℃, the smart home appliance's water pump system will not freeze, and the heat pump unit will not be running at this time. Therefore, the smart home appliance will remain in its current non-operating state, and there is no need to activate the anti-freeze mode. However, if the smart home appliance detects an ambient temperature of -10℃ (-10℃ < 3℃), then in an environment of -10℃, the smart home appliance's water pump system will freeze. Since the smart home appliance is not operating at this time, it needs to activate its anti-freeze mode. This anti-freeze mode is primarily for situations where the smart home appliance is not working and the ambient temperature is no higher than 3℃.

[0129] S205: Control the smart home appliance to operate according to the current working mode.

[0130] S206: Determine that the antifreeze mode of the smart home appliance is the first antifreeze mode.

[0131] S207: Control the smart home appliance to operate according to the first antifreeze mode, and obtain the water flow rate and outlet water temperature of the smart home appliance.

[0132] Water flow rate refers to the volume of water delivered by the smart home appliance per unit time, and water outlet temperature refers to the temperature of the water flowing through the smart home appliance.

[0133] Once the smart home appliance is set to the first antifreeze mode and is in operation, the current water flow rate and temperature of the water are detected, which is the outlet water temperature, to determine the current degree of freezing of the smart home appliance.

[0134] Understandably, since the current ambient temperature is not higher than the first preset temperature and the smart home appliance is not operating, the smart home appliance may freeze, resulting in a lower detected water flow rate than at normal ambient temperature. Alternatively, it is also possible that the detected water flow rate is equal to the water flow rate at normal ambient temperature.

[0135] For example, if the water flow rate of a smart home appliance's water pump system is 1 cubic meter per hour and the outlet water temperature is 5°C, then freezing will occur within the water pump system.

[0136] S208: When the water flow rate is less than the rated water flow rate, adjust the water flow rate to the rated water flow rate.

[0137] Rated water flow rate refers to the water flow rate delivered by the unit of a smart home appliance under normal ambient temperature. Different smart home appliances are equipped with different units, and therefore their rated water flow rates also vary.

[0138] Because smart home appliances sometimes freeze, the water flow rate is lower than the rated flow rate. In this case, the water pump speed is adjusted to match the rated flow rate. Specifically: when the water flow rate is below the rated flow rate, the pump speed is increased to increase the flow rate; when the water flow rate reaches the rated flow rate, the current pump speed is kept constant to stabilize the water flow at the rated flow rate. For example, the water pump speed of a smart home appliance under normal ambient temperature can be 600 rpm.

[0139] Understandably, when smart home appliances only experience slight freezing, simply adjusting the water flow to the rated flow rate can achieve the antifreeze effect, thus avoiding resource waste.

[0140] For example, the rated water flow rate of the current smart home motor is 5 cubic meters per hour, and the detected water flow rate is 1 cubic meter per hour. At this time, since the current water flow rate of 1 cubic meter per hour is less than the rated water flow rate of 5 cubic meters per hour, the pump speed is increased to increase the current water flow rate; when the current water flow rate matches the rated water flow rate and reaches 5 cubic meters per hour, the pump speed is kept constant to maintain the current water flow rate of 5 cubic meters per hour.

[0141] S209: Determine whether the outlet water temperature is less than or equal to the third preset temperature; if yes, proceed to step S210; if no, proceed to step S211.

[0142] The third preset temperature is used as a judgment point to indicate the degree of freezing of the water pump system of smart home appliances, for example, it can be 8℃.

[0143] The purpose of determining whether the outlet water temperature is less than or equal to the third preset temperature is to determine whether the freezing degree of the current smart home appliance water pump system is severe.

[0144] Understandably, the low ambient temperature leads to a low outlet water temperature in the water pump system, causing freezing. The degree of freezing in the water pump system of smart home appliances can be categorized as severe, normal, and slight. If the freezing is severe, the water pump system cannot operate normally, with most of the water frozen (e.g., nearly two-thirds). If the freezing is normal, the water pump system can operate normally, but a small portion of the water is frozen (e.g., nearly one-quarter). If the freezing is slight, the water pump system can operate normally, but the water is only at a low temperature and on the verge of freezing, showing only a tendency to freeze. In this case, simply maintaining the current water flow rate consistent with the rated flow rate is sufficient.

[0145] If the outlet water temperature is less than or equal to the third preset temperature, it indicates that the water pump system of the current smart home appliance is severely frozen, meaning that the water pump system cannot perform normal water circulation and most of the water is frozen. In this case, maintain the current water pump speed and stable water flow; control the operation of the smart home appliance's fan and compressor, with the compressor operating at the lowest allowed operating frequency of the current unit, to enable the unit to heat, thereby alleviating the freezing phenomenon in the water pump system. The lowest operating frequency can be, for example, 20Hz.

[0146] If the outlet water temperature is higher than the third preset temperature, it indicates that the water pump system of the current smart home appliance does not have a serious freezing phenomenon, but the degree of freezing of the current water pump system cannot be determined. At this time, the current water pump speed is maintained, and the outlet water temperature is further determined to determine the degree of freezing of the water pump system under the current environmental conditions.

[0147] For example, if the current outlet water temperature is 0℃, which is 8℃ lower than the third preset temperature, it indicates that most of the water in the pump system is frozen. In this case, maintain the current pump speed to prevent the freezing from spreading, turn on the fan, and run the compressor at 20Hz to start the unit's heating function and alleviate the freezing. If the current outlet water temperature is 10℃, which is 8℃ higher than the third preset temperature, it can only be determined that most of the water in the pump system is not frozen; further assessment is needed to determine the specific degree of freezing.

[0148] S210: Control the operation of the fan and compressor of the smart home appliance.

[0149] S211: Determine whether the outlet water temperature is lower than the fourth preset temperature; if yes, proceed to step S212; if no, proceed to step S222.

[0150] The fourth preset temperature is used to indicate the degree of freezing of the water pump system of the smart home appliance, and the fourth preset temperature is greater than the third preset temperature, for example, it can be 15℃.

[0151] The purpose of determining whether the outlet water temperature is lower than the fourth preset temperature is to determine whether the freezing degree of the current smart home appliance water pump system is slight.

[0152] If the outlet water temperature is lower than the fourth preset temperature, it indicates that the freezing level of the water pump system of the current smart home appliance is normal, that is, the water pump system can carry out normal water circulation, but some water is still frozen. At this time, keep the current water pump speed and water flow stable, control the smart home appliance to turn on the water circuit electric auxiliary heating, heat the water pump system, and alleviate the freezing phenomenon in the water pump system.

[0153] If the outlet water temperature is not lower than the fourth preset temperature, it indicates that the freezing degree of the water pump system of the current smart home appliance is slight, that is, the water pump system can carry out normal water circulation and only shows a tendency to freeze; at this time, the current water pump speed is kept stable and the water flow is kept stable, and the freezing phenomenon in the water pump system is suppressed by the flow of water.

[0154] For example, if the current outlet water temperature is 10℃, which is lower than the fourth preset temperature of 15℃ but higher than the third preset temperature by 8℃, it indicates that nearly a quarter of the water in the pump system is frozen. In this case, maintain the current pump speed and activate the electric auxiliary heating function of the water circuit to heat the pump system and alleviate the freezing phenomenon. If the current outlet water temperature is 15℃, which is equal to the fourth preset temperature of 15℃, there is no freezing phenomenon in the pump system. Simply maintain the current pump speed to maintain the rated water flow.

[0155] S212: Control the smart home appliance to turn on the water circuit electric auxiliary heating function.

[0156] S213: Determine the working state of the smart home appliance as a second working state, the second working state being used to indicate the operation of the smart home appliance.

[0157] S214: Determine whether the evaporation temperature of the smart home appliance is lower than the second preset temperature; if yes, proceed to step S215; if no, proceed to step S221.

[0158] The evaporation temperature is used to indicate the refrigerant evaporation pressure at the water-side heat exchanger. The second preset temperature is used to indicate the point at which frost formation occurs on the water-side heat exchanger of the smart home appliance; the second preset temperature can be, for example, 0°C.

[0159] The purpose of determining whether the evaporation temperature of a smart home appliance is lower than the second preset temperature is to determine whether the smart home appliance needs to activate the antifreeze mode in the current state.

[0160] Understandably, the evaporation temperature of smart home appliances is determined by the refrigerant pressure of the water-side heat exchanger. After confirming that the smart home appliance is running, the specific evaporation temperature is determined by detecting the pressure of the water-side heat exchanger and performing thermodynamic calculations based on the different evaporation temperatures corresponding to the refrigerant evaporation pressure.

[0161] If the evaporation temperature of the smart appliance is lower than the second preset temperature, it indicates that there is a possibility of frost formation in the smart appliance under the current environment. In this case, it is determined that the smart appliance needs to activate the anti-freeze mode, and the operating mode of the smart appliance in the current state is set as the second anti-freeze mode. The second anti-freeze mode is used to instruct the smart appliance to reduce its frequency; by reducing the frequency of the smart appliance's compressor, an anti-freeze effect is achieved.

[0162] If the evaporation temperature of the smart home appliance is not lower than the second preset temperature, it indicates that there is no possibility of frost formation in the smart home appliance under the current environment. At this time, it is determined that the smart home appliance does not need to start the antifreeze mode. Therefore, the current working mode of the smart home appliance remains unchanged and continues to operate in the current working mode.

[0163] For example, if the evaporation temperature of the smart appliance is -5℃, it indicates that the plates of the water-side heat exchanger are frosted. Since freezing can cause the plates to deform or even crack, the entire heat pump unit will not function properly. Therefore, in this case, the smart appliance should be switched to its second anti-freeze mode. If the evaporation temperature of the smart appliance is 10℃, it indicates that the plates of the water-side heat exchanger are not frosted. In this case, there is no need to change the operating mode of the smart appliance, and it will continue to operate normally.

[0164] S215: Determine that the antifreeze mode of the smart home appliance is the second antifreeze mode.

[0165] S216: Control the smart home appliance to operate in the second antifreeze mode, and obtain the water flow rate and outlet water temperature of the smart home appliance.

[0166] When the smart home appliance is in the second antifreeze mode and is running, the current water flow rate and temperature of the water are detected, which is the outlet water temperature. This determines the current degree of freezing of the smart home appliance and avoids the freezing effect caused by the cooling effect of the water-side heat exchanger.

[0167] S217: When the water flow rate is less than the rated water flow rate, adjust the water flow rate to the rated water flow rate.

[0168] Step S208 is similar to step S217 above, and will not be described again here.

[0169] S218: Determine whether the outlet water temperature is greater than the fifth preset temperature; if yes, proceed to step S219; if no, proceed to step S220.

[0170] The fifth preset temperature is used to indicate the judgment point for determining the frequency reduction parameters of smart home appliances, for example, it can be 3℃.

[0171] The purpose of determining whether the outlet water temperature is greater than the fifth preset temperature is to determine the frequency reduction rate of the smart home appliance's operating frequency.

[0172] Understandably, the operating frequency of smart home appliances determines the efficiency of the water-side heat exchanger, thus determining its cooling effect. A higher operating frequency results in higher efficiency and a better cooling effect. When the outlet water temperature exceeds the fifth preset temperature, frosting is not significant, but due to the low evaporation temperature, a tendency for frosting exists. In this case, the compressor frequency can be reduced to a lower setting. When the outlet water temperature is not higher than the fifth preset temperature, significant frosting occurs. At this point, both the evaporation and outlet water temperatures are low, allowing the compressor frequency to be reduced to a higher setting. The terms "low frequency" and "high frequency" here refer only to a comparison and do not imply a difference in magnitude.

[0173] If the outlet water temperature is higher than the fifth preset temperature, it indicates that the frosting phenomenon of the smart home appliance is not obvious. At this time, the compressor of the smart home appliance is controlled to reduce its frequency according to the first frequency reduction parameter, thereby reducing the cooling effect of the water-side heat exchanger and alleviating the frosting phenomenon. The frequency reduction parameter refers to the rate at which the compressor of the smart home appliance is subjected to frequency reduction. The first frequency reduction parameter can be, for example, 1Hz / min.

[0174] If the outlet water temperature is not higher than the fifth preset temperature, it indicates that the smart home appliance is experiencing frosting, and the frosting is more pronounced compared to when the outlet water temperature is higher than the fifth preset temperature. In this case, the compressor of the smart home appliance is controlled to reduce its frequency according to the second frequency reduction parameter, thereby reducing the cooling effect of the water-side heat exchanger and alleviating the frosting phenomenon. The second frequency reduction parameter can be, for example, 3Hz / min.

[0175] For example, if the outlet water temperature is 10℃, it indicates that the frosting phenomenon of the water-side heat exchanger of the smart home appliance is not obvious and there is no large area of ​​frost. In this case, the compressor frequency is reduced to 1Hz / min. If the outlet water temperature is 0℃, it indicates that the water-side heat exchanger of the smart home appliance has obvious frosting phenomenon and a large area of ​​frost. In this case, the compressor frequency is reduced to 3Hz / min. Both frequency reduction methods are to reduce the cooling effect of the water-side heat exchanger, thereby increasing the evaporation temperature of the water-side heat exchanger.

[0176] S219: Control the compressor of the smart home appliance to perform frequency reduction processing according to the first frequency reduction parameter.

[0177] S220: Control the compressor of the smart home appliance to perform frequency reduction processing according to the second frequency reduction parameter.

[0178] S221: Control the smart home appliance to operate according to the current working mode.

[0179] Step S221 is similar to step S205 above, and will not be repeated here.

[0180] S222: Obtain the antifreeze parameters of the smart home appliance, the antifreeze parameters including a first antifreeze parameter and a second antifreeze parameter.

[0181] S223: If the antifreeze parameter is the first antifreeze parameter, then according to the first antifreeze parameter, control the smart home appliance to exit the current antifreeze mode.

[0182] S224: If the antifreeze parameter is the second antifreeze parameter, then according to the second antifreeze parameter, control the smart home appliance to maintain the current antifreeze mode.

[0183] The first antifreeze parameter is used to instruct the smart home appliance to exit the antifreeze mode, and the second antifreeze parameter is used to instruct the smart home appliance to maintain the antifreeze mode.

[0184] Understandably, antifreeze parameters are obtained after the antifreeze mode is activated. When the smart appliance is running in the first antifreeze mode, the obtained antifreeze parameter is the outlet water temperature. When the smart appliance is running in the second antifreeze mode, the obtained antifreeze parameter is the evaporation temperature.

[0185] When the smart home appliance is in the first anti-freeze mode and is already running in this mode, the outlet water temperature is acquired again, and it is determined whether the outlet water temperature meets the condition for exiting the anti-freeze mode, i.e., the outlet water temperature is greater than the fourth preset temperature. When the outlet water temperature is greater than the fourth preset temperature, the corresponding anti-freeze operation is stopped, and the first anti-freeze mode is exited; when the outlet water temperature is not greater than the fourth preset temperature, the first anti-freeze mode continues to run, and the currently acquired outlet water temperature is judged. Based on the relationship between the current outlet water temperature and the third and fourth preset temperatures, the corresponding anti-freeze operation is executed.

[0186] When the smart home appliance is in the second anti-freeze mode and is already running in this mode, the evaporation temperature is acquired again, and it is determined whether the evaporation temperature meets the condition for exiting the anti-freeze mode, i.e., the evaporation temperature is greater than the second preset temperature. When the evaporation temperature is greater than the second preset temperature, the corresponding anti-freeze operation is stopped, and the second anti-freeze mode is exited; when the evaporation temperature is not greater than the fourth preset temperature, the second anti-freeze mode continues to run, and the currently acquired evaporation temperature is judged. Based on the relationship between the current outlet water temperature and the fifth preset temperature, the corresponding anti-freeze operation is executed.

[0187] At this time, the first antifreeze parameter is that the outlet water temperature is greater than the fourth preset temperature or the evaporation temperature is greater than the second preset temperature, and the second antifreeze parameter is that the outlet water temperature is not greater than the fourth preset temperature or the evaporation temperature is not greater than the second preset temperature.

[0188] For example, if the outlet water temperature is 16℃, meaning the first antifreeze parameter is an outlet water temperature greater than 15℃, it indicates that the smart home appliance's water pump system is not freezing, and the first antifreeze mode is exited. If the outlet water temperature is 10℃, meaning the second antifreeze parameter is an outlet water temperature not greater than 15℃, it indicates that the smart home appliance's water pump system is still freezing, and the first antifreeze mode continues to run. If the evaporation temperature is 5℃, meaning the first antifreeze parameter is an evaporation temperature greater than 0℃, it indicates that the smart home appliance's water-side heat exchanger is not frosting, and the second antifreeze mode is exited. If the evaporation temperature is -1℃, meaning the second antifreeze parameter is an evaporation temperature not greater than 0℃, it indicates that the smart home appliance's water-side heat exchanger is still frosting, and the second antifreeze mode continues to run.

[0189] Optionally, if the smart home appliance is in the second anti-freeze mode and has already run the anti-freeze mode, and the evaporation temperature does not meet the conditions for exiting the second anti-freeze mode, the compressor of the smart home appliance will continue to be frequency-reduced.

[0190] Because the compressors of smart home appliances have a lower limit to their operating frequency, they cannot remain in a frequency-reduced state indefinitely. Smart home appliances have a minimum operating frequency, and this minimum operating frequency varies depending on the specific unit configuration of the smart appliance; for example, it can be 20Hz.

[0191] When the evaporation temperature does not meet the conditions for exiting the second antifreeze mode (i.e., the evaporation temperature is not higher than the second preset temperature), the compressor frequency is reduced. Regardless of whether the first or second frequency reduction parameter is used, when the compressor frequency drops to the minimum operating frequency, the smart home appliance is controlled to shut down the compressor to prevent malfunctions.

[0192] Optionally, after controlling the smart home appliance to exit the current antifreeze mode according to the first antifreeze parameter, the operating parameters of the smart home appliance are reacquired according to a preset cycle.

[0193] Based on the re-acquired operating parameters, the operating frequency and judgment temperature are judged again to determine whether the smart home appliance needs to be protected against freezing. When the smart home appliance needs to be protected against freezing, it is controlled to operate in the corresponding anti-freezing mode.

[0194] The anti-freeze treatment method provided in this embodiment acquires the ambient temperature, the unit's operating frequency, and the evaporation temperature, and then determines the acquired temperature and frequency information. Based on different determination results, different anti-freeze modes are run to achieve the preset anti-freeze effect for the smart home appliance. After determining the appropriate anti-freeze mode, anti-freeze parameters are acquired. Based on different anti-freeze parameters, it is determined whether the smart home appliance should exit the current anti-freeze mode. After the smart home appliance exits the anti-freeze mode, the operating parameters are collected again according to a preset cycle, and the operating parameters are determined again. Based on the determination results, it is determined whether the smart home appliance should re-enter the anti-freeze mode. This method solves the defect of system freezing and cracking that occurs in low-temperature environments, thereby ensuring the normal operation of the unit, further improving the working efficiency of the smart home appliance, and enhancing the user experience.
