Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular to a household water machine water flow shortage warning method, device, electronic device and readable medium. Background Art

[0002] As people's requirements for the comfort of living environment continue to increase, household water machines have been widely used. When the water flow of a household water machine is insufficient, it is easy for the household water machine to malfunction (for example, local high temperature or local low temperature inside damages the household water machine components (such as plate change)). The household water machine water flow insufficient warning is a technology that warns the household water machine when the water flow of the household water machine is insufficient. At present, when issuing an early warning for a household water machine, the method usually adopted is: directly predict the water flow of the household water machine based on the outlet water temperature of the household water machine, the inlet water temperature of the household water machine, and the heating (cooling or heating) capacity of the household water machine, and issue an early warning when the water flow is low.

[0003] However, when the above method is used to warn household water machines of insufficient water flow, the following technical problems often occur:

[0004] The water flow rate of the household water machine is predicted directly based on the outlet water temperature, inlet water temperature and heating (cooling or heating) capacity of the household water machine. When the water flow rate is low, an early warning is issued. During the startup phase of the household water machine, the relationship between water flow rate and temperature is relatively complex. The error of predicting the water flow rate of the household water machine based only on the outlet water temperature, inlet water temperature and heating (cooling or heating) capacity of the household water machine is large. During the startup phase, the compressor in the household water machine has not yet reached its normal operating state, resulting in an unstable heat exchange process. The temperature difference between the inlet and outlet water may fluctuate violently in a short period of time, which in turn leads to a low accuracy rate of the predicted water flow rate and an increase in the number of false alarms and missed alarms of the household water machine water flow shortage early warning.

[0005] The above information disclosed in this Background section is only for enhancement of understanding of the background of the inventive concept and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art. Summary of the invention

[0006] The content of this disclosure is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this disclosure is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0007] Some embodiments of the present disclosure provide household water machine water flow shortage warning methods, devices, electronic devices and computer-readable media to solve one or more of the technical problems mentioned in the above background technology section.

[0008] In a first aspect, some embodiments of the present disclosure provide a method for early warning of insufficient water flow for a household water machine, the method comprising: in response to receiving household water machine startup information sent by a temperature control system indicating the startup of a preset household water machine, wherein the household water machine startup information includes the household water machine startup time and temperature control mode information; within a preset time period after the water machine startup time, based on the temperature control mode information, performing the following early warning steps: in response to determining that the temperature control mode information indicates the start of heating, obtaining the household water machine outlet water temperature, condensation temperature, and outlet refrigerant temperature of the water side heat exchanger after condensation; based on the household water machine outlet water temperature, the condensation temperature, and outlet refrigerant temperature of the water side heat exchanger after condensation, controlling the preset household water machine to perform a water flow insufficient early warning in the heating mode; after the preset time period of the water machine startup time, obtaining energy supply information corresponding to the preset household water machine, and obtaining the system time as the current time; based on the energy supply information and the current time, performing water flow insufficient monitoring and early warning on the preset household water machine, wherein the energy supply information includes an energy supply value.

[0009] In a second aspect, some embodiments of the present disclosure provide a household water machine water flow insufficient warning device, the device comprising: a receiving unit, configured to respond to receiving household water machine startup information sent by a temperature control system indicating the start of a preset household water machine, wherein the household water machine startup information includes the household water machine startup time and temperature control mode information; a first warning unit, configured to perform the following warning steps based on the temperature control mode information within a preset time period after the water machine startup time: in response to determining that the temperature control mode information indicates the start of heating, obtain the household water machine outlet water temperature, condensing temperature, water side exchange The outlet refrigerant temperature of the heat exchanger after condensation; based on the outlet water temperature of the household water machine, the condensation temperature, and the outlet refrigerant temperature of the water-side heat exchanger after condensation, the preset household water machine is controlled to issue a water flow shortage warning in the heating mode; an acquisition unit is configured to obtain energy supply information corresponding to the preset household water machine after a preset time period of the water machine start-up time, and obtain the system time as the current time; a second warning unit is configured to monitor and warn of water flow shortage for the preset household water machine based on the energy supply information and the current time, wherein the energy supply information includes an energy supply value.

[0010] In a third aspect, some embodiments of the present disclosure provide an electronic device comprising: one or more processors; a storage device on which one or more programs are stored, and when the one or more programs are executed by the one or more processors, the one or more processors implement the method described in any implementation manner of the above-mentioned first aspect.

[0011] In a fourth aspect, some embodiments of the present disclosure provide a computer-readable medium having a computer program stored thereon, wherein when the program is executed by a processor, the method described in any implementation manner of the above-mentioned first aspect is implemented.

[0012] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through the household water machine water flow insufficient warning method of some embodiments of the present disclosure, the number of false alarms and missed alarms of the household water machine water flow insufficient warning is reduced. Specifically, the reason for the increase in the number of false alarms and missed alarms of the household water machine water flow insufficient warning is that: the water flow of the household water machine is predicted directly based on the outlet water temperature of the household water machine, the inlet water temperature of the household water machine, and the temperature (cooling or heating) capacity of the household water machine, and an early warning is issued when the water flow is low. In the startup stage of the household water machine, the relationship between water flow and temperature is relatively complex. Only based on the outlet water temperature of the household water machine, the inlet water temperature of the household water machine, and the temperature (cooling or heating) capacity of the household water machine, the single prediction of the water flow of the household water machine has a large error. In the startup stage, the compressor in the household water machine has not yet reached its normal operating state, resulting in an unstable heat exchange process. The temperature difference between the inlet and outlet water may fluctuate violently in a short period of time, which in turn leads to a low accuracy of the predicted water flow, and an increase in the number of false alarms and missed alarms of the household water machine water flow insufficient warning. Based on this, in some embodiments of the present disclosure, the household water machine water flow insufficient warning method, first, in response to receiving the household water machine startup information sent by the temperature control system, which indicates the startup of the preset household water machine, wherein the household water machine startup information includes the household water machine startup time and the temperature control mode information. Thus, the startup time and temperature control mode information of the household water machine can be obtained. Then, within the preset time period after the water machine startup time, based on the temperature control mode information, the following warning steps are performed: the first sub-step, in response to determining that the temperature control mode information indicates the start of heating, the household water machine outlet water temperature, condensation temperature, and outlet refrigerant temperature of the water side heat exchanger after condensation are obtained. Thus, in the household water machine startup stage, multi-point temperature parameters (i.e., household water machine outlet water temperature, condensation temperature, and outlet refrigerant temperature of the water side heat exchanger after condensation) reflecting the heat exchange efficiency and fluid state of the preset household water machine can be obtained. Based on the household water machine outlet water temperature, the condensation temperature, and the outlet refrigerant temperature of the water side heat exchanger after condensation, the preset household water machine is controlled to perform water flow insufficient warning in the heating mode. Therefore, in the heating mode of the startup phase, multi-point temperature data can be integrated to more comprehensively understand the heat exchange process and fluid state, and thus more accurately warn of insufficient water flow. Afterwards, after the preset time period of the water machine startup time, the energy supply information corresponding to the preset household water machine is obtained, and the system time is obtained as the current time. Based on the energy supply information and the current time, the preset household water machine is monitored and warned of insufficient water flow, wherein the energy supply information includes the energy supply value. Therefore, an insufficient water flow warning can be issued in the stable phase after the preset household water machine is started.Also, during the preset household water machine startup phase, the impact of water flow on multiple temperature parameters (i.e. household water machine outlet water temperature, condensation temperature, outlet refrigerant temperature after condensation of the water side heat exchanger) is comprehensively judged, so that the heat exchange process and fluid state are more comprehensively understood, the error caused by a single measurement is reduced, and the water flow shortage warning can be more accurately issued. The number of false alarms and missed alarms of household water machine water flow shortage warnings is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0023] Figure 1 The process 100 of some embodiments of the household water machine water flow insufficient warning method according to the present disclosure is shown. The household water machine water flow insufficient warning method comprises the following steps:

[0024] Step 101, in response to receiving household water machine start-up information sent by a temperature control system indicating that a preset household water machine is started.

[0025] In some embodiments, the executing body (e.g., a computing device) of the household water machine water flow insufficient warning method may respond to receiving household water machine startup information sent by the temperature control system that indicates the startup of a preset household water machine. The household water machine startup information includes the water machine startup time and the temperature control mode information. The temperature control system may be a control device or system for monitoring and adjusting the indoor temperature, such as an intelligent thermostat. The water machine startup time may be the time when the household water machine starts running. The temperature control mode information may be information indicating a heating mode or a cooling mode. The temperature control mode information may be represented by a code or a character string. For example, the temperature control mode information may be "HEAT" or "0" to indicate a heating mode, or the heating mode information may be "COOL" or "1" to indicate a cooling mode.

[0026] Step 102: within a preset time period after the water machine is started, based on the temperature control mode information, perform the following early warning steps:

[0027] Step 1021, in response to determining that the temperature control mode information indicates that heating is turned on, obtain the outlet water temperature of the household water machine, the condensation temperature, and the outlet refrigerant temperature of the water-side heat exchanger after condensation.

[0028] In some embodiments, the execution subject may obtain the outlet water temperature of the household water machine, the condensation temperature, and the outlet refrigerant temperature of the water side heat exchanger after condensation in response to determining that the temperature control mode information indicates that heating is turned on. The condensation temperature may be the temperature at which the refrigerant in the condenser of the household water machine condenses from gas to liquid under a certain pressure. In practice, the execution subject may detect the condensation pressure by detecting the built-in pressure sensor of the condenser. Then, the condensation pressure is converted into a saturated condensation temperature. The outlet refrigerant temperature of the water side heat exchanger after condensation may be the temperature of the refrigerant outlet from the heat exchanger. Optionally, in practice, the execution subject may obtain the outlet water temperature of the household water machine through a temperature sensor installed at the water outlet of a preset household water machine. The execution subject may obtain the condensation temperature through a temperature sensor installed in the condenser of the preset household water machine. The execution subject may obtain the outlet refrigerant temperature of the water side heat exchanger after condensation through a temperature sensor installed at the condensation outlet of the water side heat exchanger.

[0029] In some optional implementations of some embodiments, in response to determining that the temperature control mode information indicates that heating is turned on, after obtaining the outlet water temperature, condensation temperature, and outlet refrigerant temperature of the water-side heat exchanger after condensation, the execution subject may further perform the following steps:

[0030] The first step is to obtain the outlet water temperature, evaporation temperature and suction temperature of the household water machine in response to determining that the above temperature control mode information indicates that refrigeration is turned on. The evaporation temperature may be the temperature at which the refrigerant evaporates and boils in the evaporator. In practice, the execution body may detect the evaporation pressure through a pressure sensor in the evaporator, and then convert the evaporation pressure into a saturated evaporation temperature. Optionally, in practice, the execution body may obtain the temperature in the evaporator as the evaporation temperature (evaporation temperature) through a temperature sensor installed in the evaporator of the preset household water machine. The execution body may obtain the temperature of the suction port of the evaporator as the suction temperature through a temperature sensor installed at the suction port of the evaporator of the preset household water machine.

[0031] The second step is to control the preset household water machine to issue a water flow shortage warning in the cooling mode based on the water outlet temperature of the household water machine, the evaporation temperature, and the intake temperature.

[0032] In some optional implementations of some embodiments, the execution subject may control the preset household water machine to issue a water flow shortage warning in the cooling mode based on the outlet water temperature of the household water machine, the evaporation temperature, and the suction temperature through the following steps:

[0033] In response to determining that the outlet water temperature of the household water machine is less than or equal to the fourth preset value, the difference between the evaporation temperature and the outlet water temperature of the household water machine is determined as the second temperature difference.

[0034] In response to determining that the second temperature difference is less than or equal to the fifth preset value and the suction temperature is less than or equal to the sixth preset value, the preset household water machine is controlled to stop refrigeration, and the preset household water machine is controlled to send a warning message indicating insufficient water flow. In practice, the execution subject may send a signal indicating the stop of refrigeration to the temperature control system to control the preset household water machine to stop refrigeration. The execution subject may send a warning start message for starting insufficient water flow warning to the warning module corresponding to the preset household water machine through a control interface (such as GPIO, serial port, CAN bus, etc.) to control the warning module to send a warning message indicating insufficient water flow (for example, an acoustic and optical signal). The warning start message may be a command to send a warning in text form indicating the start of insufficient water flow warning. For example, a JSON or XML format command indicating the start of insufficient water flow warning. The warning module may be, but is not limited to, one of the following: a buzzer, a speaker, an LED light. The warning module may be installed inside or outside the preset household water machine.

[0035] Step 1022, based on the outlet water temperature of the household water machine, the condensation temperature, and the outlet refrigerant temperature of the water-side heat exchanger after condensation, control the preset household water machine to issue a water flow shortage warning in the heating mode.

[0036] In some embodiments, the execution entity may control the preset household water machine to issue a water flow shortage warning in the heating mode based on the outlet water temperature of the household water machine, the condensation temperature, and the outlet refrigerant temperature of the water-side heat exchanger after condensation.

[0037] In some optional implementations of some embodiments, the execution subject may control the preset household water machine to issue a water flow shortage warning in the heating mode based on the outlet water temperature of the household water machine, the condensation temperature, and the outlet refrigerant temperature of the water-side heat exchanger after condensation through the following steps:

[0038] In the first step, in response to determining that the outlet water temperature of the household water machine is greater than or equal to a first preset value, a difference between the condensation temperature and the outlet water temperature of the household water machine is determined as a first temperature difference.

[0039] In the second step, in response to determining that the first temperature difference is greater than or equal to the second preset value and the outlet refrigerant temperature of the water-side heat exchanger after condensation is greater than or equal to the third preset value, the preset household water machine is controlled to stop heating, and the preset household water machine is controlled to send an early warning message indicating insufficient water flow. In practice, the execution subject can send a signal indicating the stop of heating to the temperature control system to control the preset household water machine to stop heating. The execution subject can send an early warning start message for starting an early warning of insufficient water flow to the early warning module corresponding to the preset household water machine through a control interface (such as GPIO, serial port, CAN bus, etc.) to control the early warning module to send an early warning message indicating insufficient water flow (for example, an acoustic and optical signal). The early warning start message can be a command to send an early warning indicating the start of insufficient water flow in text form. For example, a JSON or XML format command indicating the start of an early warning of insufficient water flow. The early warning module can be, but is not limited to, one of the following: a buzzer, a speaker, an LED light. The early warning module can be installed inside or outside the preset household water machine.

[0040] Step 103, after a preset time period of the water machine start time, obtain energy supply information corresponding to the preset household water machine, and obtain the system time as the current time.

[0041] In some embodiments, the above-mentioned execution subject can obtain the energy supply information corresponding to the above-mentioned preset household water machine after a preset time period of the above-mentioned water machine start-up time, and obtain the system time as the current time. In practice, the above-mentioned execution subject can obtain the energy supply information of the above-mentioned preset household water machine from a preset storage file. Among them, the above-mentioned preset storage file can be a file for storing the performance parameters (heating and cooling capacity (energy supply value Q), energy efficiency ratio (COP)) of the above-mentioned preset household water machine, the model, size, weight and other parameter information of the equipment. For example, the above-mentioned file can be a PDF or Word document.

[0042] Step 104, based on the energy supply information and the current time, monitor and warn of insufficient water flow for the preset household water machine.

[0043] In some embodiments, the execution subject may monitor and warn the preset household water machine of insufficient water flow based on the energy supply information and the current time. The energy supply information includes an energy supply value. The function value may represent the value of the heating and cooling capacity of the preset household water machine. For example, the energy supply value may be 3.5kW.

[0044] In some optional implementations of some embodiments, the execution subject may perform water flow insufficient monitoring and early warning on the preset household water machine based on the energy supply information and the current time through the following steps:

[0045] In the first step, based on the current time and the above energy supply information, the following monitoring steps are performed:

[0046] The first sub-step is to collect the outlet water temperature of the preset household water machine at the current time. In practice, the execution subject may collect the outlet water temperature of the preset household water machine at the current time through a temperature sensor installed at the water outlet of the preset household water machine.

[0047] The second sub-step is to collect the water inlet temperature of the preset household water machine at the current time. In practice, the execution subject may collect the water inlet temperature of the preset household water machine at the current time through a temperature sensor installed at the water inlet of the preset household water machine.

[0048] The third sub-step is to generate inlet and outlet water temperature difference information based on the temperature control mode information, the outlet water temperature, and the inlet water temperature, wherein the inlet and outlet water temperature difference information includes a temperature difference value.

[0049] The fourth sub-step is to determine the product of the above temperature difference value and the specific heat capacity of water as the intermediate value.

[0050] The fifth sub-step is to determine the ratio of the energy supply value included in the energy supply information to the intermediate value as the water flow information.

[0051] The sixth sub-step is, in response to determining that the value corresponding to the water flow information is less than or equal to the preset mass flow value, controlling the preset household water machine to stop running, and controlling the preset household water machine to issue a water flow shortage warning. The preset mass flow value may be a preset mass of water flowing through the preset household water machine within a preset time period. The execution subject may send a signal indicating that the preset household water machine is stopped to the temperature control system, so as to control the preset household water machine to stop running. The execution subject may send an early warning start message for starting a water flow shortage early warning to the early warning module of the preset household water machine, so as to control the early warning module of the preset household water machine to issue a water flow shortage early warning.

[0052] The seventh sub-step is, in response to determining that the numerical value corresponding to the above water flow information is greater than the preset mass flow value, obtaining the system time again after a preset interval time period of the above current time.

[0053] The eighth sub-step is to determine the acquired system time as the current time to update the current time.

[0054] The ninth sub-step is to execute the above monitoring step again according to the updated current time and the above energy supply information.

[0055] In some optional implementations of some embodiments, the execution subject may generate the inlet and outlet water temperature difference information based on the temperature control mode information, the outlet water temperature, and the inlet water temperature through the following steps:

[0056] In the first step, in response to determining that the temperature control mode information indicates that heating is turned on, the difference between the outlet water temperature and the inlet water temperature is determined as a first temperature difference value.

[0057] The second step is to determine the first temperature difference value as the inlet and outlet water temperature difference information.

[0058] In a third step, in response to determining that the temperature control mode information indicates that cooling is turned on, a difference between the water inlet temperature and the water outlet temperature is determined as a second temperature difference value.

[0059] The fourth step is to determine the second temperature difference value as the inlet and outlet water temperature difference information.

[0060] In the process of adopting technical solutions to solve the problems mentioned in the background technology, the following problems are often accompanied:

[0061] When the water flow of the user's water machine is insufficient, in order to enable the household water machine to be used normally more quickly, the water flow of the household water machine in the subsequent startup is usually increased by directly controlling the preset water pump speed of the household water machine. However, in addition to the slow water pump speed, other factors also cause the low water flow of the household water machine (for example, whether the water supply pump is working normally, whether the filter is blocked). Directly controlling the preset water pump speed of the household water machine without checking the water supply pump and filter, when there is a problem with the water supply pump or the filter is blocked, adjusting the water pump speed cannot solve the problem of low water flow of the household water machine. Forcibly increasing the water flow by adjusting the water pump speed may bring a greater burden to the pump, accelerating its wear and aging.

[0062] In the face of the above technical problems, the inventors decided to adopt the following solutions:

[0063] In some optional implementations of some embodiments, the above execution subject may further perform the following steps:

[0064] In the first step, the time point at which the above-mentioned preset household water machine sends out a warning message indicating insufficient water flow is determined as a reference time point.

[0065] The second step is to obtain the current consumption value sequence of the water supply pump of the above-mentioned preset household water machine within the preset reference time period before the above-mentioned reference time point. In practice, the above-mentioned execution entity can obtain the current consumption value sequence of the water supply pump of the above-mentioned preset household water machine within the preset reference time period before the above-mentioned reference time point from a data acquisition system (such as a SCADA system, a PLC control system, etc.). The above-mentioned current consumption sequence includes various current consumption values. For example, the above-mentioned current consumption sequence can be "(3.5A, 3.7A, 4.0A, 3.8A)". The above-mentioned data acquisition system can be a system for storing the current value collected by the preset current sensor during the real-time monitoring of the water pump operation and for storing the water inlet and outlet pressure information collected in real time by each pressure sensor of each pressure sensor corresponding to each preset filter.

[0066] In the third step, in response to determining that there is a preset reference value in the current consumption value sequence, information characterizing the abnormality of the water supply pump is sent to the maintenance terminal. The preset reference value may be 0. The information characterizing the abnormality of the water supply pump may be text information. For example, the information characterizing the abnormality of the water supply pump may be "abnormality of the water supply pump".

[0067] In the fourth step, in response to determining that there is no preset reference value in the above-mentioned current consumption value sequence, the above-mentioned current consumption value sequence is subjected to amplitude anomaly detection processing to obtain amplitude anomaly detection information. In practice, the above-mentioned execution subject may determine the mean value of each current consumption value included in the current consumption value sequence as the first value. Then, the above-mentioned execution subject may determine the difference between the above-mentioned each current consumption value and the above-mentioned first value as each second value. Next, the above-mentioned execution subject may determine the absolute value of each second value in the above-mentioned each second value as the target value to obtain each target value. In response to determining that there is a target value greater than or equal to the preset value in the above-mentioned each target value, the above-mentioned execution subject may determine the text information characterizing the amplitude anomaly as the amplitude anomaly detection information. In response to determining that the above-mentioned each target value is less than the above-mentioned preset value, the above-mentioned execution subject may determine the text information characterizing the normal amplitude as the amplitude anomaly detection information. For example, the above-mentioned amplitude anomaly detection information may be one of the following: normal amplitude, abnormal amplitude.

[0068] Step 5: In response to determining that the amplitude abnormality detection information indicates an amplitude abnormality, information indicating the abnormality of the water supply pump is sent to a maintenance terminal. The maintenance terminal may be a terminal device of a maintenance person, such as a mobile phone or a computer.

[0069] Step 6: In response to determining that the amplitude abnormality detection information indicates that the amplitude is normal, obtain the water inlet and outlet pressure information sequences of each preset filter between the water supply pump and the preset household water machine within the preset reference time period. Among them, each water inlet and outlet pressure information sequence corresponds to each filter identifier of each preset filter, and the water inlet and outlet pressure information sequence in each water inlet and outlet pressure information sequence corresponds to the filter identifier in each filter identifier, and each water inlet and outlet pressure information in the water inlet and outlet pressure information sequence includes an inlet pressure value and an outlet pressure value. In practice, the execution subject can obtain the water inlet and outlet pressure information sequences of each preset filter between the water supply pump and the preset household water machine within the preset reference time period from the data acquisition system. The inlet pressure value can represent the pressure of the water inlet of the preset filter at the preset time. The outlet pressure value can represent the pressure of the water outlet of the preset filter at the preset time.

[0070] Step 7: For each of the above-mentioned water inlet and outlet pressure information sequences, perform the following blockage detection process:

[0071] The first sub-step is to generate a pressure difference sequence based on the water inlet and outlet pressure information sequence. In practice, for each water inlet and outlet pressure information in the water inlet and outlet pressure information sequence, the execution subject may determine the difference between the water inlet pressure value included in the water inlet and outlet pressure information and the water outlet pressure value included in the water inlet and outlet pressure information as the pressure difference, and obtain the pressure difference sequence.

[0072] In the second sub-step, each pressure difference in the pressure difference sequence having a pressure difference greater than a preset value is determined as each target pressure difference.

[0073] In a third sub-step, the number of the target pressure differences among the above target pressure differences is determined as the target number.

[0074] A fourth sub-step, in response to determining that the target number is greater than a preset number, determines the filter identifier corresponding to the water inlet and outlet pressure information sequence as a blocked filter identifier.

[0075] The fifth sub-step is to send the information indicating the filter blockage and the above-mentioned blocked filter identifier to the maintenance terminal.

[0076] In step 8, in response to determining that the determined number of blocked filter identifiers is zero, the frequency converter is controlled to adjust the water pump speed of the preset household water machine to a preset speed. For example, the preset speed may be 3000 rpm.

[0077] The above technical solution and its related contents, as an inventive point of the embodiment of the present disclosure, solve the technical problem that "when there is a problem with the water supply pump or the filter is blocked, adjusting the opening of the water inlet valve cannot solve the problem of the small water flow of the household water machine. Forcibly increasing the water flow by adjusting the valve may bring a greater burden to the pump, accelerating its wear and aging". The factors that lead to the accelerated wear and aging of the water supply pump are often as follows: directly controlling the pump speed of the preset household water machine without detecting the water supply pump and the filter. When there is a problem with the water supply pump or the filter is blocked, adjusting the pump speed cannot solve the problem of the small water flow of the household water machine. Forcibly increasing the water flow by the pump speed may bring a greater burden to the pump, accelerating its wear and aging. If the above factors are solved, the effect of slowing down the wear and aging of the water supply pump can be achieved. In order to achieve this effect, first, the time point when the preset household water machine sends out a warning message indicating insufficient water flow is determined as a reference time point. Thus, the reference time point when the water flow of the household water machine is insufficient can be obtained. Afterwards, the current consumption value sequence of the water supply pump of the above-mentioned preset household water machine within the preset reference time period before the above-mentioned reference time point is obtained. Then, in response to determining that there is a preset reference value in the above-mentioned current consumption value sequence, information characterizing the abnormality of the water supply pump is sent to the maintenance terminal. Thus, when a reference value (for example, 0) appears in the current consumption value sequence of the water supply pump, the information of the abnormality of the water supply pump can be sent to the maintenance terminal. In response to determining that there is no preset reference value in the above-mentioned current consumption value sequence, the above-mentioned current consumption value sequence is subjected to amplitude abnormality detection processing to obtain amplitude abnormality detection information. Thus, when there is no preset reference value (for example, 0) in the current consumption value sequence, that is, when the water supply pump is working, the amplitude of the current consumption value sequence of the water supply pump can be subjected to abnormality detection. In response to determining that the above-mentioned amplitude abnormality detection information characterizes amplitude abnormality, information characterizing the abnormality of the water supply pump is sent to the maintenance terminal. In response to determining that the amplitude abnormality detection information indicates that the amplitude is normal, the water inlet and outlet pressure information sequences of each preset filter between the water supply pump and the preset household water machine within the preset reference time period are obtained, wherein each water inlet and outlet pressure information sequence corresponds to each filter identifier of each preset filter, and the water inlet and outlet pressure information sequence in each water inlet and outlet pressure information sequence corresponds to the filter identifier in each filter identifier, and each water inlet and outlet pressure information in the water inlet and outlet pressure information sequence includes an inlet pressure value and an outlet pressure value. Thus, each water inlet and outlet pressure information sequence for blockage detection of each preset filter can be obtained when no abnormality occurs in the water supply pump. Afterwards, for each water inlet and outlet pressure information sequence in each water inlet and outlet pressure information sequence, the following blockage detection process is performed: the first sub-step is to generate a pressure difference sequence based on the water inlet and outlet pressure information sequence.In the second sub-step, each pressure difference in the pressure difference sequence that is greater than a preset value is determined as each target pressure difference. In the third sub-step, the number of target pressure differences in the target pressure differences is determined as the target number. In the fourth sub-step, in response to determining that the target number is greater than the preset number, the filter identifier corresponding to the water inlet and outlet pressure information sequence is determined as the blocked filter identifier. In the fifth sub-step, the information characterizing the blockage of the filter and the blocked filter identifier are sent to the maintenance terminal. In this way, each filter can be detected for blockage, and the information characterizing the blockage of the filter and the identifier of the blocked filter are sent to the maintenance terminal. In the sixth sub-step, in response to determining that the number of blocked filter identifiers determined is zero, the frequency converter is controlled to adjust the water pump speed of the preset household water machine to the preset speed. In this way, the water flow can be increased by adjusting the water pump speed when the water flow is insufficient, the water supply pump is normal, and the filter is not blocked. Also, when the water flow of the household water machine is small, the water supply pump is detected for abnormality and each preset filter is detected for blockage. When the water flow of the household water machine is small, the water supply pump is normal, and the filter is not blocked, the water pump speed of the preset household water machine is adjusted to the preset speed to solve the problem of small water flow of the household water machine. At the same time, it also avoids forcibly adjusting the pump speed without any detection, reducing the risk of wear and aging of the water supply pump.

[0078] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through the household water machine water flow insufficient warning method of some embodiments of the present disclosure, the number of false alarms and missed alarms of the household water machine water flow insufficient warning is reduced. Specifically, the reason for the increase in the number of false alarms and missed alarms of the household water machine water flow insufficient warning is that: the water flow of the household water machine is predicted directly based on the outlet water temperature of the household water machine, the inlet water temperature of the household water machine, and the temperature (cooling or heating) capacity of the household water machine, and an early warning is issued when the water flow is low. In the startup stage of the household water machine, the relationship between water flow and temperature is relatively complex. Only based on the outlet water temperature of the household water machine, the inlet water temperature of the household water machine, and the temperature (cooling or heating) capacity of the household water machine, the single prediction of the water flow of the household water machine has a large error. In the startup stage, the compressor in the household water machine has not yet reached its normal operating state, resulting in an unstable heat exchange process. The temperature difference between the inlet and outlet water may fluctuate violently in a short period of time, which in turn leads to a low accuracy of the predicted water flow, and an increase in the number of false alarms and missed alarms of the household water machine water flow insufficient warning. Based on this, in some embodiments of the present disclosure, the household water machine water flow insufficient warning method, first, in response to receiving the household water machine startup information sent by the temperature control system, which indicates the startup of the preset household water machine, wherein the household water machine startup information includes the household water machine startup time and the temperature control mode information. Thus, the startup time and temperature control mode information of the household water machine can be obtained. Then, within the preset time period after the water machine startup time, based on the temperature control mode information, the following warning steps are performed: the first sub-step, in response to determining that the temperature control mode information indicates the start of heating, the household water machine outlet water temperature, condensation temperature, and outlet refrigerant temperature of the water side heat exchanger after condensation are obtained. Thus, in the household water machine startup stage, multi-point temperature parameters (i.e., household water machine outlet water temperature, condensation temperature, and outlet refrigerant temperature of the water side heat exchanger after condensation) reflecting the heat exchange efficiency and fluid state of the preset household water machine can be obtained. Based on the household water machine outlet water temperature, the condensation temperature, and the outlet refrigerant temperature of the water side heat exchanger after condensation, the preset household water machine is controlled to perform water flow insufficient warning in the heating mode. Therefore, in the heating mode of the startup phase, multi-point temperature data can be integrated to more comprehensively understand the heat exchange process and fluid state, and thus more accurately warn of insufficient water flow. Afterwards, after the preset time period of the water machine startup time, the energy supply information corresponding to the preset household water machine is obtained, and the system time is obtained as the current time. Based on the energy supply information and the current time, the preset household water machine is monitored and warned of insufficient water flow, wherein the energy supply information includes the energy supply value. Therefore, an insufficient water flow warning can be issued in the stable phase after the preset household water machine is started.Also, because during the preset household water machine startup phase, by comprehensively judging the impact of water flow on multiple temperature parameters (i.e. household water machine outlet water temperature, condensation temperature, and outlet refrigerant temperature after condensation of the water-side heat exchanger), a more comprehensive understanding of the heat exchange process and fluid state is achieved, reducing the error caused by a single measurement, and thus more accurately providing warnings for insufficient water flow, reducing the number of false alarms and missed alarms for household water machine water flow insufficient warnings.
