Description

Technical Field

[0001] The present application belongs to the technical field of smart home appliances, and specifically relates to an antifreeze treatment method, device, equipment and computer storage medium. Background Art

[0002] With the development of science and technology, energy saving and environmental protection have gradually become hot topics. Therefore, under the premise of meeting their own needs, most users are more willing to choose to use smart home appliances with green energy saving and low energy consumption.

[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 the prior art, air source heat pump units are usually used to provide users with winter heating and summer cooling functions. 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, when the low-temperature air source heat pump is not in use in winter or during refrigeration and defrosting, there is a possibility of freezing of the water-side heat exchanger and freezing of the water pump. At present, the low-temperature air source heat pump mostly uses plate heat exchangers as the water-side heat exchangers of the unit. The single-layer channel of the plate heat exchanger is narrow, and freezing will cause the plate to deform or even crack, which will cause the entire heat pump unit to fail to work properly. In addition, during refrigeration or defrosting, since the water-side heat exchanger is in a low-pressure area, the refrigerant evaporation temperature is too low, which will also cause the plate heat exchanger to freeze and crack.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0084] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0085] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

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

[0087] With the development of science and technology, energy saving and environmental protection have gradually become hot topics. Therefore, under the premise of meeting their own needs, most users are more willing to choose to use smart home appliances with green energy saving and low energy consumption.

[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 the prior art, air source heat pump units are usually used to provide users with winter heating and summer cooling functions. 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, after the unit is installed, if it is not started in winter and the water pump is not circulating, the system will freeze and crack. Common system freezing and cracking problems include: freezing and cracking of water pumps and freezing and cracking of water-side heat exchangers. In particular, the current low-temperature air source heat pumps also use plate heat exchangers as the water-side heat exchangers of the unit. The single-layer channel of the plate heat exchanger is narrow, and freezing will cause the plate to deform or even crack, causing the entire heat pump unit to fail to work normally; 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 will also cause the plate heat exchanger to freeze and crack.

[0090] In response to the above problems, the present application provides an antifreeze treatment method.

[0091] First, the implementation scenarios involved in this application are described.

[0092] With the continuous development of science and technology, smart home appliances need to be applied in more and more environments. Not only should we consider the operation of smart home appliances in normal temperature environments, but we also need to ensure that smart home appliances can operate normally in low temperature environments. The smart home appliances involved in this application can be, for example, a water heater equipped with multiple temperature sensors and pressure sensors.

[0093] Smart home appliances can obtain the external ambient temperature and the evaporation temperature of the unit through temperature sensors and pressure sensors to determine whether the smart home appliances are running in antifreeze mode.

[0094] The antifreeze treatment method provided by the present application obtains the ambient temperature and the operating frequency and evaporation temperature of the unit, and determines the obtained temperature and frequency information; according to different determination results, auxiliary heating or unit frequency reduction can be used to achieve the antifreeze effect, thereby realizing the use of different methods to calculate the real-time heating capacity of the unit to match the dynamic balance of the unit's cooling load and then control the compressor frequency. This method solves the defect of system freezing and cracking of the unit in a low temperature environment, thereby ensuring the normal operation of the unit, further improving the working efficiency of smart home appliances, and improving the user experience.

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

[0096] Figure 1 The process of the antifreeze treatment method provided in the embodiment of the present application Figure 1 The execution subject of this embodiment may be, for example, a processor of a smart home appliance. Figure 1 As shown, the antifreeze treatment method provided in this embodiment includes:

[0097] S101: Acquire operating parameters of the smart home appliance, where the operating parameters include: operating frequency and determination temperature.

[0098] Among them, the operating frequency is the working frequency of the smart home appliance unit, the judgment temperature is used to determine whether the current smart home appliance enters the antifreeze mode, and there is a correlation between the operating frequency and the judgment temperature.

[0099] It can be understood that the operating frequency belongs to the operating parameter information of the smart home appliance; the determination temperature can be a plurality of detection temperatures, and different determination temperatures are used for determination according to different operating environments.

[0100] For example, the heat pump unit configured in the smart home appliance can detect the compressor frequency, ambient temperature, fluorine side pressure of the water-fluorine heat exchanger, etc. Then, according to the compressor frequency obtained by the current heat pump unit, the operating frequency of the current smart home appliance can be determined; according to the ambient temperature obtained by the current heat pump unit through the temperature sensor, the judgment temperature of the current smart home appliance can be determined; according to the fluorine side pressure of the water-fluorine heat exchanger obtained by the current heat pump unit through the pressure sensor, the refrigerant evaporation temperature can be obtained by thermodynamic conversion, and thus the judgment temperature of the current smart home appliance can also be determined.

[0101] S102: Determine a working state of the smart home appliance according to the operating frequency, where the working state is used to indicate whether the smart home appliance is currently operating.

[0102] The operating frequency changes with the working state of the smart home appliance, and different operating frequencies correspond to different working states of the smart home appliance. Therefore, the current operating frequency of the smart home appliance can be obtained as a specific frequency value; according to this frequency value, it can be intuitively reflected whether the current smart home appliance is running, thereby determining whether the current working state of the smart home appliance is running or not running.

[0103] For example, when the compressor frequency is 0Hz, it indicates that the heat pump unit is not running, and at this time, the heat pump unit of the smart home appliance is in a non-working state; when the compressor frequency is 40Hz, it indicates that the heat pump unit is running, and at this time, the heat pump unit of the smart home appliance is in a working state.

[0104] S103: Determine an antifreeze mode of the smart home appliance according to the working state and the determined temperature, and control the smart home appliance to operate according to the antifreeze mode.

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

[0106] Smart home appliances have different reasons for freezing and cracking of the system under different working conditions. For example, when the heat pump unit of the smart home appliance is not running, the water pump does not circulate, causing the water pump to freeze and crack. When the heat pump unit of the smart home appliance is running, during the refrigeration or defrosting process, the water-side heat exchanger is in a low-pressure area and the refrigerant evaporation temperature is too low, causing the water-side heat exchanger to freeze and crack.

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

[0108] For example, when the heat pump unit of the smart home appliance is not running, the ambient temperature can be obtained, and the current ambient temperature can be used as the judgment temperature to determine whether the antifreeze mode needs to be run, and the smart home appliance can be controlled to execute the result after the determination. When the heat pump unit of the smart home appliance is running, the evaporation temperature at the water-side heat exchanger can be obtained, and the evaporation temperature can be used as the judgment temperature to determine whether the antifreeze mode needs to be run, and the smart home appliance can be controlled to execute the result after the determination.

[0109] It can be understood that when the heat pump unit of the smart home appliance is not running, the antifreeze mode determined at this time is aimed at the problem of water pump freezing and cracking caused by external environmental factors; when the heat pump unit of the smart home appliance is running, the antifreeze mode determined at this time is aimed at the problem of water side heat exchanger freezing and cracking caused by the refrigeration function of the water side heat exchanger.

[0110] The antifreeze processing method provided in this embodiment obtains the operating frequency and the judgment temperature, and judges the obtained temperature and frequency information; according to different judgment results, the corresponding antifreeze mode of the smart home appliance is determined, and the smart home appliance is operated in the antifreeze mode. This method solves the defect of system freezing and cracking of the unit in a low temperature environment, thereby ensuring the normal operation of the unit and improving the user experience.

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

[0112] S201: Acquire operating parameters of the smart home appliance, where the operating parameters include: operating frequency and determination temperature.

[0113] Step S201 is similar to the above step S101 and will not be described again.

[0114] S202: Determine whether the operating frequency is greater than a preset operating frequency; if so, execute step S213; if not, execute step S203.

[0115] The preset operating frequency refers to the frequency at which the smart home appliance is not in operation, for example, it may be 0 Hz.

[0116] The purpose of this step of judging 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, that is, the smart home appliance is not operating. At this time, the non-operating working state of the smart home appliance is determined as a working state.

[0119] It can be understood that the operating frequency of the smart home appliance only exists when it is greater than or equal to the preset operating frequency, and when the operating frequency of the smart home appliance is equal to the preset operating frequency, the working state of the smart home appliance is the first working state; when the operating frequency of the smart home appliance is greater than the preset operating frequency, the working state of the smart home appliance is the second working state.

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

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

[0122] S204: Determine whether the ambient temperature is greater than a first preset temperature; if so, execute step S205; if not, execute step S206.

[0123] The ambient temperature is the ambient temperature of the smart home appliance. The first preset temperature is used to indicate whether the water pump system of the smart home appliance is frozen. The first preset temperature may be 3°C, for example.

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

[0125] If the ambient temperature is greater than the first preset temperature, it indicates that there is no possibility of freezing of the smart home appliance in the current environment. At this time, it is determined that the smart home appliance does not need to start the antifreeze mode. Then, the current working mode of the smart home appliance is controlled unchanged and continues to operate in the current working mode.

[0126] If the ambient temperature is not greater than the first preset temperature, it indicates that the smart home appliance may freeze under the current environment. At this time, it is determined that the smart home appliance needs to start the antifreeze mode, and the working mode of the smart home appliance in the current state is determined to be the first antifreeze mode. The first antifreeze mode is used to instruct the smart home appliance to perform auxiliary heating; by performing auxiliary heating on the system of the smart home appliance, the antifreeze effect is achieved.

[0127] It is understandable that when the smart home appliance is not running, the main factor affecting the activation of the antifreeze mode of the smart home appliance is the external environment temperature. For example, the water pump system will freeze when the temperature is below 0°C.

[0128] For example, if the smart home appliance detects that the current ambient temperature is 10℃, 10℃>3℃; then, in an environment of 10℃, the water pump system of the smart home appliance does not freeze, and the heat pump unit of the smart home appliance is not running at this time, then the smart home appliance is kept in the current non-operating state, and there is no need to start the antifreeze mode. If the smart home appliance detects that the current ambient temperature is -10℃, -10℃<3℃; then, in an environment of -10℃, the water pump system of the smart home appliance is frozen. Since the smart home appliance is not running at this time, the antifreeze mode of the smart home appliance needs to be started, and the antifreeze mode is mainly used when the smart home appliance is not working and the ambient temperature is not greater 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 water outlet temperature of the smart home appliance.

[0132] Among them, water flow refers to the volume of water delivered by the smart home appliance per unit time, and the water outlet temperature refers to the temperature of the water flow inside the smart home appliance.

[0133] When it is determined that the current working mode of the smart home appliance is the first antifreeze mode and is running, the current water flow of the smart home appliance is detected, and the temperature of the current water flow, that is, the water outlet temperature, is detected to determine the current freezing degree of the smart home appliance.

[0134] It is understandable that, since the current external environment temperature is not greater than the first preset temperature and the smart home appliance is not running, the smart home appliance is frozen, and the detected water flow is less than the water flow at the normal environment temperature. In addition, it is also possible that the detected water flow is equal to the water flow at the normal environment temperature.

[0135] For example, the water flow rate of the water pump system of a smart home appliance may be 1 cubic meter per hour, and the water outlet temperature is 5°C, then there is freezing in 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] The rated water flow rate refers to the water flow rate delivered by the unit of the smart home appliance under normal ambient temperature. Different smart home appliances are equipped with different units, and the corresponding rated water flow rates are also different.

[0138] Since the current smart home appliance is frozen, the water flow rate is less than the rated water flow rate. At this time, the water pump speed is adjusted to keep the current water flow rate consistent with the rated water flow rate, that is, when it is detected that the water flow rate has not reached the rated water flow rate, the water flow rate is increased by increasing the water pump speed; when the water flow rate reaches the rated water flow rate, the current water pump speed is kept unchanged to stabilize the current water volume at the rated water flow rate. The water pump speed of the smart home appliance at normal ambient temperature can be, for example, 600 rpm.

[0139] It is understandable that when there is only slight freezing in the smart home appliances, the anti-freeze effect can be achieved by simply adjusting the water flow to the rated water flow, thereby avoiding waste of resources.

[0140] For example, the rated water flow of the current smart home appliance unit is 5 cubic meters per hour, and the detected water flow is 1 cubic meter per hour. At this time, the current water flow of 1 cubic meter per hour is less than the rated water flow of 5 cubic meters per hour, so the water pump speed is increased to increase the current water flow; when the current water flow is consistent with the rated water flow and reaches 5 cubic meters per hour, the current water pump speed is kept unchanged to keep the current water flow at 5 cubic meters per hour.

[0141] S209: Determine whether the outlet water temperature is less than or equal to a third preset temperature; if so, execute step S210; if not, execute step S211.

[0142] The third preset temperature is used to indicate the judgment point of the freezing degree of the water pump system of the smart home appliance, for example, it may be 8°C.

[0143] The purpose of judging 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 serious.

[0144] It is understandable that due to the low external ambient temperature, the outlet water temperature in the water pump system is also low, which leads to the freezing of the water pump system. The degree of freezing of the water pump system of smart home appliances can be divided into: severe, normal and slight. If the degree of freezing is severe, the water pump system cannot operate normally, and most of the water in the system is frozen, for example, nearly two-thirds of the water may be frozen; if the degree of freezing is normal, the water pump system can operate normally, but a small amount of water in the system is frozen, for example, nearly a quarter of the water may be frozen; if the degree of freezing is slight, the water pump system can operate normally, and the water in the system is only in a critical state of low temperature and freezing, and only shows a tendency to freeze. At this time, it is only necessary to keep the current water flow consistent with the rated water flow.

[0145] If the outlet water temperature is less than or equal to the third preset temperature, it indicates that the freezing degree of the water pump system of the current smart home appliance is serious, that is, the water pump system cannot perform normal water circulation and most of the water is frozen; at this time, the current water pump speed is maintained to stabilize the water flow; the fan and compressor of the smart home appliance are controlled to operate, and the operating frequency of the compressor is the minimum operating frequency allowed by the current unit, so that the unit heats up, thereby alleviating the freezing phenomenon in the water pump system. The minimum operating frequency can be 20Hz, for example.

[0146] If the outlet water temperature is greater than the third preset temperature, it indicates that there is no serious freezing phenomenon in the water pump system of the current smart home appliance, 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°C, which is lower than the third preset temperature of 8°C, it indicates that most of the water in the water pump system is frozen; at this time, the current water pump speed is maintained to prevent the freezing phenomenon from expanding, and the fan is turned on, and the compressor runs at 20Hz, so that the unit starts heating and alleviates the current freezing phenomenon. If the current outlet water temperature is 10°C, which is higher than the third preset temperature of 8°C, it can only be determined that most of the water in the water pump system is not frozen, and the specific degree of freezing needs further judgment.

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

[0149] S211: Determine whether the outlet water temperature is less than a fourth preset temperature; if so, execute step S212; if not, execute step S222.

[0150] The fourth preset temperature is used to indicate the judgment point of the freezing degree 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 may be 15°C.

[0151] The purpose of judging whether the outlet water temperature is less 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 degree 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, the current water pump speed is maintained to stabilize the water flow, and the smart home appliance is controlled to turn on the electric auxiliary heating of the water circuit to heat the water pump system and alleviate the freezing phenomenon in the water pump system.

[0153] If the outlet water temperature is not less than the fourth preset temperature, it indicates that the degree of freezing 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 be frozen; at this time, the current water pump speed is maintained to stabilize the water flow, and only the flow of water is used to suppress the freezing phenomenon in the water pump system.

[0154] For example, if the current outlet water temperature is 10°C, which is lower than the fourth preset temperature of 15°C, but higher than the third preset temperature of 8°C, it means that nearly a quarter of the water in the water pump system is frozen; at this time, the current water pump speed is maintained, the water circuit electric auxiliary heating function is turned on, the water pump system is heated, and the current freezing phenomenon is alleviated. If the current outlet water temperature is 15°C, which is equal to the fourth preset temperature of 15°C, there is no freezing phenomenon in the water pump system at this time, and only the current water pump speed is maintained to maintain the rated water flow.

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

[0156] S213: Determine that the working state of the smart home appliance is a second working state, where the second working state is used to indicate that the smart home appliance is running.

[0157] S214: Determine whether the evaporation temperature of the smart home appliance is less than a second preset temperature; if so, execute step S215; if not, execute step S221.

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

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

[0160] It is understandable that 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 value of the evaporation temperature is determined by detecting the water-side heat exchanger pressure of the unit and performing thermodynamic conversion according to the refrigerant evaporation pressure corresponding to different evaporation temperatures.

[0161] If the evaporation temperature of the smart home appliance is lower than the second preset temperature, it indicates that the smart home appliance may frost under the current environment. At this time, it is determined that the smart home appliance needs to start the antifreeze mode, and the working mode of the smart home appliance in the current state is determined to be the second antifreeze mode. The second antifreeze mode is used to instruct the smart home appliance to perform frequency reduction processing; by reducing the frequency of the compressor of the smart home appliance, the antifreeze effect is achieved.

[0162] If the evaporation temperature of the smart home appliance is not less than the second preset temperature, it indicates that there is no possibility of frost on 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. Then, the current working mode of the smart home appliance is controlled unchanged and continues to operate in the current working mode.

[0163] For example, if the evaporation temperature of the smart home appliance is -5°C, it indicates that there is frost on the plate of the water-side heat exchanger of the smart home appliance. Since freezing will cause the plate to deform or even crack, the entire heat pump unit cannot work properly. Therefore, the smart home appliance is controlled to the second antifreeze mode. If the evaporation temperature of the smart home appliance is 10°C, it indicates that there is no frost on the plate of the water-side heat exchanger of the smart home appliance. At this time, there is no need to change the working mode of the smart home appliance and keep the smart home appliance working 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 and outlet water temperature of the smart home appliance.

[0166] When it is determined that the current working mode of the smart home appliance is the second antifreeze mode and is running, the current water flow of the smart home appliance is detected, and the temperature of the current water flow, that is, the water outlet temperature, is detected, so as to determine the current freezing degree of the smart home appliance and avoid the freezing effect caused by the refrigeration effect generated when the water-side heat exchanger is working.

[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 the above step S217 and will not be described again here.

[0169] S218: Determine whether the outlet water temperature is greater than the fifth preset temperature; if so, execute step S219; if not, execute step S220.

[0170] The fifth preset temperature is used to indicate a judgment point for determining the frequency reduction parameters of the smart home appliance, for example, it may be 3°C.

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

[0172] It can be understood that the operating frequency of the smart home appliance determines the working efficiency of the water-side heat exchanger, thereby determining the cooling effect of the water-side heat exchanger; the greater the operating frequency, the higher the working efficiency of the water-side heat exchanger, and the higher its cooling effect. When the outlet water temperature is greater than the fifth preset temperature, the frosting phenomenon of the smart home appliance is not obvious, but due to the low evaporation temperature, there is a frosting trend. At this time, the compressor of the smart home appliance can be reduced in frequency at a low frequency rate. When the outlet water temperature is not greater than the fifth preset temperature, the smart home appliance has obvious frosting. At this time, the evaporation temperature and the outlet water temperature are both low, and the compressor of the smart home appliance can be reduced in frequency at a high frequency rate. The low frequency and high frequency involved here are only for comparison between the two, and there is a difference in size.

[0173] If the outlet water temperature is greater 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 perform frequency reduction processing according to the first frequency reduction parameter to reduce the cooling effect of the water side heat exchanger, thereby alleviating the frosting phenomenon. The frequency reduction parameter refers to the rate at which the compressor of the smart home appliance is frequency reduced. The first frequency reduction parameter can be, for example, 1 Hz / min.

[0174] If the outlet water temperature is not greater than the fifth preset temperature, it indicates that the smart home appliance has frosting, and the frosting is more obvious than when the outlet water temperature is greater than the fifth preset temperature. At this time, the compressor of the smart home appliance is controlled to perform frequency reduction processing according to the second frequency reduction parameter to reduce the cooling effect of the water side heat exchanger, thereby 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 means that the frosting phenomenon of the water side heat exchanger of the smart home appliance is not obvious, and there is no large-scale frosting. At this time, the compressor frequency is reduced by 1Hz / min; if the outlet water temperature is 0℃, it means that the water side heat exchanger of the smart home appliance has obvious frosting phenomenon, and there is a large-scale frosting. At this time, the compressor frequency is reduced by 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 the above step S205 and will not be described again here.

[0180] S222: Acquire antifreeze parameters of the smart home appliance, where the antifreeze parameters include a first antifreeze parameter and a second antifreeze parameter.

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

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

[0183] Among them, 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] It is understandable that the antifreeze parameter is obtained after the antifreeze mode is run. When the antifreeze mode of the smart home appliance is the first antifreeze mode, the antifreeze parameter obtained is the water outlet temperature. When the antifreeze mode of the smart home appliance is the second antifreeze mode, the antifreeze parameter obtained is the evaporation temperature.

[0185] When the working mode of the smart home appliance is the first antifreeze mode and the antifreeze mode has been running, the outlet water temperature is obtained again, and it is determined whether the outlet water temperature meets the condition for exiting the antifreeze mode, that is, 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 antifreeze operation is stopped and the first antifreeze mode is exited; when the outlet water temperature is not greater than the fourth preset temperature, the first antifreeze mode is continued to run, and the currently obtained outlet water temperature is determined, and the corresponding antifreeze operation is performed according to the relationship between the current outlet water temperature and the third preset temperature and the fourth preset temperature.

[0186] When the working mode of the smart home appliance is the second antifreeze mode and the antifreeze mode has been running, the evaporation temperature is obtained again, and it is determined whether the evaporation temperature meets the condition for exiting the antifreeze mode, that is, the evaporation temperature is greater than the second preset temperature. When the evaporation temperature is greater than the second preset temperature, the corresponding antifreeze operation is stopped and the second antifreeze mode is exited; when the evaporation temperature is not greater than the fourth preset temperature, the second antifreeze mode is continued to run, and the currently obtained evaporation temperature is determined, and the corresponding antifreeze operation is performed according to the relationship between the current water outlet temperature and the fifth preset temperature.

[0187] At this time, the first antifreeze parameter is that the water outlet 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 water outlet 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°C, that is, the first antifreeze parameter is that the outlet water temperature is greater than 15°C, then it indicates that there is no freezing in the water pump system of the smart home appliance, and the first antifreeze mode is exited at this time; if the outlet water temperature is 10°C, that is, the second antifreeze parameter is that the outlet water temperature is not greater than 15°C, then it indicates that there is still freezing in the water pump system of the smart home appliance, and the first antifreeze mode continues to run; if the evaporation temperature is 5°C, that is, the first antifreeze parameter is that the evaporation temperature is greater than 0°C, then it indicates that there is no frost on the water side heat exchanger of the smart home appliance, and the second antifreeze mode is exited at this time; if the evaporation temperature is -1°C, that is, the second antifreeze parameter is that the evaporation temperature is not greater than 0°C, then it indicates that there is still frost on the water side heat exchanger of the smart home appliance, and the second antifreeze mode is continued to run.

[0189] Optionally, when the working mode of the smart home appliance is the second antifreeze mode and the antifreeze mode has been running, and the evaporation temperature does not meet the conditions for exiting the second antifreeze mode, the compressor of the smart home appliance continues to be frequency-reduced.

[0190] Since the operating frequency of the compressor of the smart home appliance has a lower limit, it is impossible to always be in frequency reduction. The operating frequency of the smart home appliance has a minimum operating frequency. Since different smart home appliances are configured with different units, the minimum operating frequency is also different, for example, it can be 20Hz.

[0191] When the evaporation temperature does not meet the condition for exiting the second antifreeze mode, that is, the evaporation temperature is not greater than the second preset temperature, the compressor is controlled to reduce the frequency. Regardless of whether the frequency reduction process is performed using the first frequency reduction parameter or the second frequency reduction parameter, when the frequency of the compressor is reduced to the minimum operating frequency, the smart home appliance is controlled to shut down the compressor to avoid malfunction of the smart home appliance.

[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 re-acquired according to a preset cycle.

[0193] According to the re-acquired operating parameters, the operating frequency and the judgment temperature are judged again to determine whether the smart home appliances need to be antifreeze treated. When the smart home appliances need to be antifreeze treated, the smart home appliances are controlled to operate in the corresponding antifreeze mode.

[0194] The antifreeze processing method provided in this embodiment obtains the ambient temperature and the operating frequency and evaporation temperature of the unit, and determines the obtained temperature and frequency information; according to different determination results, runs different antifreeze modes to enable the smart home appliance to achieve the preset antifreeze effect; after determining to run the corresponding antifreeze mode, obtains antifreeze parameters; according to different antifreeze parameters, determines whether the smart home appliance exits the current antifreeze mode; after the smart home appliance exits the antifreeze mode, re-collects the operating parameters according to the preset cycle, and determines the operating parameters again, and determines whether the smart home appliance enters the antifreeze mode again according to the determination result. This method solves the defect of system freezing and cracking of the unit in a low temperature environment, thereby ensuring the normal operation of the unit, further improving the working efficiency of the smart home appliance, and improving the user experience.
