[0053] Please refer to Figure 1 The embodiment of the present invention provides a method for identifying dirt and blockage in a closed-loop water circulation system 100. The method includes:

[0054] S01, obtaining a first water pressure value of the closed circulating water system 100;

[0055] S03, when the first water pressure value is greater than or equal to the set water pressure threshold, controlling the water pump 14 to operate with set parameters and obtaining water flow data;

[0056] S05, after the water flow data is stable, recording the first water flow data;

[0057] S07: When the first water flow rate data is less than a set value, output a system dirty and blocked prompt message.

[0058] In the above-mentioned dirty blockage identification method, when the first water pressure value of the closed-loop circulating water system 100 is greater than or equal to the set water pressure threshold, the water pump 14 is controlled to operate with the set parameters and obtain the first water flow data. When the first water flow data is less than the set value, it can be determined that the system is dirty and blocked, and a system dirty blockage prompt message is output, so that the user can promptly discover the dirty blockage of the system and improve the user experience.

[0059] Specifically, in one embodiment, the closed-loop circulating water system 100 can use water as a heat transfer medium. When the water pump 14 is running, the flow of water can be accelerated, thereby improving the heat transfer efficiency of the closed-loop circulating water system 100. It is understood that in other embodiments, the closed-loop circulating water system 100 can also use other fluids as heat transfer media, not limited to water. When the water pump 14 is running, the flow of the heat transfer medium can be accelerated.

[0060] Please combine Figure 2In one embodiment, the closed-loop circulating water system 100 may include a heat exchanger 16 and a thermal device 18. The thermal device 18 includes a heat exchange device and / or a heat storage device. The heat exchange device includes, but is not limited to, a heat exchanger, a coil, and floor heating, and the heat storage device includes, but is not limited to, a water tank. The heat exchanger 16, the water pump 14, and the thermal device 18 are sequentially connected via pipelines to form a circulating water circuit. When the water pump 14 is activated, the water flow rate in the pipeline can be increased, thereby improving the heat exchange effect. The closed-loop circulating water system 100 can operate in cooling mode or heating mode.

[0061] In the prior art, after long-term use of a closed-loop water circulation system 100, impurities in the heat exchange medium gradually accumulate on the filter screen in the pipeline, causing clogging of the filter screen and affecting the reliability and heat transfer performance of the closed-loop water circulation system 100. Current solutions primarily rely on regular on-site maintenance to clean the filter 38, or wait until the system experiences a protection or malfunction before troubleshooting and cleaning the filter screen. This results in delays in timely detection and resolution, impacting normal use.

[0062] In the embodiment of the present invention, please combine Figure 2 The closed circulating water system 100 is provided with a water flow detection device 20 and a water pressure detection device 22, which can obtain the water flow value and water pressure value in the pipeline of the closed circulating water system 100. Figure 3 The closed circulating water system 100 may include a control component 44, which is electrically connected to the water pump 14, the water flow detection device 20 and the water pressure detection device 22. The control component 44 can obtain data output by the water flow detection device 20 and the water pressure detection device 22, and control the operation and shutdown of the water pump 14.

[0063] The control component 44 may be pre-set with a set water pressure threshold and a set value. The set water pressure threshold and set value may be fixed or adjustable. The specific values ​​of the water pressure threshold and set value may be determined based on empirical data, testing, simulation, etc. and stored in the closed-loop water circulation system 100, and are not specifically limited in the present invention.

[0064] When the closed-loop water circulation system 100 begins operation, the water pressure detection device 22 continuously detects the water pressure in the pipeline, and the control component 44 can obtain a first water pressure value. When the first water pressure value detected by the water pressure detection device 22 is greater than or equal to a set water pressure threshold, the control component 44 controls the water pump 14 to operate at the set parameters. The set parameters can be specifically defined based on actual conditions and are not specifically limited in this invention.

[0065] The water flow detection device 20 continuously detects the water flow in the pipeline, and the control component 44 can obtain water flow data. After the water flow data stabilizes, the control component 44 records the first water flow data. Optionally, the water flow data can be considered stable if it remains within a preset fluctuation range for a preset duration. The present invention does not specifically limit the preset duration and preset fluctuation range. In one example, the control component 44 can determine that the water flow data is stable if the fluctuation range of the water flow data remains within ±5% for a preset duration (e.g., 5 minutes).

[0066] If the first water flow rate data is less than a set value, the control component 44 can output a system blockage prompt. In one embodiment, the control component 44 can control the closed-loop water circulation system 100 to issue a prompt. For example, the control component 44 can control the closed-loop water circulation system 100 to issue a signal reminder, including but not limited to sound and light, or send the prompt message to the user's terminal to notify the user to check the blockage status of the closed-loop water circulation system 100. The user's terminal includes but is not limited to a mobile phone, tablet computer, personal computer, wearable smart device, etc. In summary, this allows users to promptly detect system blockage, improving the user experience.

[0067] When the first water flow data is greater than or equal to the set value, the control component 44 sends a detection completion signal, and the control system exits the detection of dirt and blockage identification.

[0068] In some embodiments, obtaining the first water pressure value of the closed circulating water system 100 includes: obtaining the first water pressure value of the closed circulating water system 100 when the closed circulating water system 100 is powered on again or the water pump 14 has not been running for a period of time greater than a set time threshold.

[0069] In this way, the accuracy of the dirt and blockage identification method can be improved.

[0070] Specifically, in one embodiment, re-energizing may refer to the process of re-energizing the machine to restore it to an operable state after the machine stops operating due to power outage, maintenance, failure, etc. When the closed-loop water system 100 is powered on again, the water pressure detection device 22 continuously detects the water pressure value in the pipeline, and the control component 44 can obtain a first water pressure value. When the first water pressure value is greater than or equal to the set water pressure threshold, the control component 44 controls the water pump 14 to operate with set parameters and obtain water flow data. After the water flow data stabilizes, the first water flow data is recorded. When the first water flow data is less than the set value, the control component 44 outputs a system dirty blockage prompt message to allow the user to promptly detect dirty blockage in the system.

[0071] In one embodiment, the continuous non-operation of the water pump 14 may mean that the water pump 14 has not performed any pumping operation for a period of time due to system shutdown, maintenance, etc. The control component 44 can detect the continuous non-operation time of the water pump 14. When the continuous non-operation time of the water pump 14 is greater than the set time threshold, the control component 44 obtains the first water pressure value through the water pressure detection device 22. When the first water pressure value is greater than or equal to the set water pressure threshold, the control component 44 controls the water pump 14 to operate with the set parameters and obtains water flow data. After the water flow data stabilizes, the first water flow data is recorded. When the first water flow data is less than the set value, the control component 44 outputs a system blockage prompt message to allow the user to promptly detect the system blockage.

[0072] The specific value of the set time threshold can be determined and stored in the closed-loop water circulation system 100 based on empirical values, testing, simulation, etc., and the present invention does not specifically limit this. The set time threshold can be fixed or adjustable. In one embodiment, the set time threshold can be adjusted based on the dirt and blockage conditions of the closed-loop water circulation system 100, or the closed-loop water circulation system 100 can adjust it based on user input. In one example, the range of the set time threshold is 24 hours to 48 hours.

[0073] In some embodiments, the set parameter includes a rated speed or a maximum speed of the water pump 14 .

[0074] In this way, the operation of the water pump 14 can be controlled by the rotation speed of the water pump 14 .

[0075] Specifically, when the closed-loop water circulation system 100 is powered on again or the water pump 14 has not been running for a period greater than a set time threshold, the control component 44 can control the water pump 14 to operate at the rated speed or maximum speed of the water pump 14, so that the heat exchange medium flows at a faster speed, thereby improving detection efficiency and accuracy.

[0076] The rated speed and maximum speed of the water pump 14 can be stored in the closed circulating water system 100. When the closed circulating water system 100 is powered on again or the water pump 14 has not been running for a period of time greater than a set time threshold, the control component 44 can read the above-mentioned set parameters to control the operation of the water pump 14.

[0077] The set parameters may be fixed or adjustable, which is not specifically limited in the present invention. Optionally, the water pump 14 may be a variable frequency water pump.

[0078] In some embodiments, the set value is the larger of a first preset value and a second preset value, where the second preset value = K × Q0, where K is 0.5 to 1, and Q0 is the second water flow data. The dirty blockage identification method includes: controlling the water pump 14 to operate at set parameters and obtaining a second water pressure value of the closed-loop circulating water system 100; if the second water pressure value is greater than or equal to a set water pressure threshold, recording the second water flow data after the water flow data stabilizes; and if the second water flow data is greater than or equal to the first preset value, storing the second water flow data.

[0079] In this way, the accuracy of the dirt and blockage identification method can be improved to a certain extent.

[0080] Specifically, when the closed-loop water system 100 begins commissioning, the control component 44 controls the water pump 14 to operate at set parameters. The water pressure detection device 22 continuously detects the water pressure within the pipeline, and the control component 44 can obtain a second water pressure value. The control component 44 can also obtain water flow data within the pipeline through the water flow detection device 20. If the second water pressure value is greater than or equal to the set water pressure threshold, the control component 44 can record the second water flow data after it stabilizes, which can be used as a basis for subsequent system identification of dirt and blockage.

[0081] When the second water flow data is greater than or equal to the first preset value, the control component 44 stores the second water flow data for use in a subsequent determination of a dirt and blockage identification method by the system.

[0082] Optionally, the first preset value is adjustable. The specific value of the first preset value can be determined and stored in the closed-loop circulating water system 100 based on empirical values, testing, simulation, etc., and the present invention does not specifically limit this. In one example, the first preset value can be the minimum flow rate at which the system can operate.

[0083] After the closed water circulation system 100 completes the above-described water flow data storage process, if the closed water circulation system 100 is powered on again or the water pump 14 has not been running for a period exceeding a set time threshold, the system will subsequently perform a blockage identification. When the first water pressure value of the closed water circulation system 100 is greater than or equal to the set water pressure threshold, the control component 44 controls the water pump 14 to operate at the set parameters and obtain the first water flow data. If the first water flow data is less than the set value, the control component 44 outputs a system blockage prompt message.

[0084] Optionally, the set value is the larger of the first preset value and the second preset value, which ensures, to a certain extent, that the system can maintain sufficient water flow for normal operation under all operations. The first preset value and the second preset value can be determined and stored in the closed circulating water system 100 based on empirical values, testing, simulation, etc., and the present invention is not specifically limited to this.

[0085] In this embodiment of the present invention, the second preset value is calculated by K×Q0, where Q0 is the second water flow data obtained in the water flow data storage process described above, and the coefficient K ranges from 0.5 to 1. By adjusting the coefficient k, the system can flexibly adapt to different operating conditions and installation scenarios, thereby improving the safety and reliability of the system to a certain extent.

[0086] K is between 0.5 and 1, i.e., 0.5 ≤ K ≤ 1. In some examples, K = 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1, or other values ​​greater than or equal to 0.5 and less than or equal to 1. The value of K can be determined based on factors such as operating conditions, actual installation scenario, and actual flow requirements.

[0087] The second preset value may be within the range of 0.5×Q0 to Q0 depending on the value of K, that is, 0.5×Q0≤second preset value≤Q0. In some examples, the second preset value = 0.5×Q0, 0.55×Q0, 0.6×Q0, 0.65×Q0, 0.7×Q0, 0.75×Q0, 0.8×Q0, 0.85×Q0, 0.9×Q0, 0.95×Q0, Q0, or other values ​​greater than or equal to 0.5×Q0 and less than or equal to Q0.

[0088] In some embodiments, the blockage identification method includes: outputting insufficient water pressure prompt information when the second water pressure value is less than a set water pressure threshold.

[0089] In this way, insufficient water pressure in the system can be discovered in time, so that water replenishment measures can be taken in time.

[0090] Specifically, when the closed-loop water circulation system 100 begins debugging and running, the control component 44 controls the water pump 14 to operate with set parameters, the water pressure detection device 22 continuously detects the water pressure in the pipeline, and the control component 44 can obtain a second water pressure value. When the second water pressure value detected by the water pressure detection device 22 is less than the set water pressure threshold, the control component 44 outputs a water pressure insufficient prompt message. In one embodiment, the control component 44 can control the closed-loop water circulation system 100 to issue a prompt message, for example, the control component 44 controls the closed-loop water circulation system 100 to issue a signal reminder including but not limited to sound, light, etc., or send a prompt message to the user's terminal to notify the user to check the water pressure of the closed-loop water circulation system 100. The user's terminal includes but is not limited to a mobile phone, tablet computer, personal computer, wearable smart device, etc. Therefore, the user can promptly discover that the system has insufficient water pressure. Optionally, after receiving the water pressure insufficient prompt message, the user can operate the control component 44 to replenish water to the system to increase the water pressure.

[0091] After the control component 44 outputs a warning message indicating insufficient water pressure, the water pressure detection device 22 continues to re-test the water pressure in the pipe. As the system replenishes water, the water pressure gradually increases. When the second water pressure value detected by the water pressure detection device 22 is greater than or equal to the set water pressure threshold, the control component 44 obtains water flow data through the water flow detection device 20. Once the water flow data stabilizes, the control component 44 records the second water flow data.

[0092] In certain embodiments, the blockage identification method includes: after outputting a system blockage prompt message, outputting a system blockage inspection and cleaning instruction.

[0093] In this way, users can be guided to quickly check and solve dirt and blockage problems.

[0094] Specifically, after outputting the system blockage warning message, the control component 44 will output system blockage inspection and cleaning instructions. Optionally, the system blockage inspection includes, but is not limited to, prompts such as confirming the blockage warning message, confirming system shutdown, checking the filter 38, checking the pipes, and checking the water pump 14. The cleaning instructions include, but are not limited to, prompts such as cleaning the filter 38, cleaning the pipes, cleaning the water pump 14, and restarting the system. Therefore, after receiving the blockage warning message, the user can quickly inspect the system and resolve the blockage according to the blockage inspection and cleaning instructions.

[0095] It is understandable that dirt blockage may also be caused by factors outside the filter. Therefore, the dirt blockage identification method of the embodiment of the present invention can also be applied to a circulating water system without a filter.

[0096] In one embodiment, the closed-loop water circulation system 100 includes a machine-visual display, on which blockage warning information and system blockage inspection and cleaning instructions can be alternately displayed. It is understood that the control component 44 can also transmit the system blockage inspection and cleaning instructions to a user's terminal, allowing the user to view the system blockage inspection and cleaning instructions. User terminals include, but are not limited to, mobile phones, tablet computers, personal computers, wearable smart devices, and the like.

[0097] In certain embodiments, the blockage identification method includes: after outputting a system blockage inspection and cleaning instruction, resetting the system blockage prompt according to a manual reset signal.

[0098] In this way, the correct maintenance and stable operation of the system can be ensured to a certain extent.

[0099] Specifically, in one embodiment, the cleaning instructions may include a manual reset prompt. After outputting the system blockage inspection and cleaning instructions, the control component 44 may output a manual reset prompt. After the user performs a blockage inspection and cleaning according to the system blockage inspection and cleaning instructions, they can perform a manual reset operation on the system according to the manual reset prompt. The manual reset operation generates a manual reset signal. Based on the manual reset signal, the control component 44 re-enters normal operating mode and re-enters the automatic blockage detection test until the test is completed and then automatically exits, thereby ensuring proper maintenance and stable operation of the system to a certain extent.

[0100] In certain embodiments, the dirty blockage identification method includes: obtaining a forced exit detection signal, and exiting the dirty blockage detection process according to the forced exit detection signal.

[0101] This provides users with operational flexibility to a certain extent.

[0102] Specifically, in one embodiment, after control component 44 outputs a system blockage warning, the user may instruct control component 44 to exit detection due to reasons such as being unable to immediately clean the system. Upon receiving the forced exit detection signal, control component 44 controls the system to exit the blockage detection process. Specifically, the system no longer outputs blockage warning information based on the blockage identification method, and the system continues to operate. Therefore, manually exiting detection provides users with a degree of operational flexibility to accommodate diverse needs.

[0103] It is understood that after a user manually forces the system to exit the dirty blockage detection function, the control component 44 will automatically resume the dirty blockage detection function after a set recovery time, thereby protecting the normal operation of the system. The present invention does not impose specific limitations on the set recovery time. In one example, the control component 44 will automatically resume the dirty blockage detection function 48 hours after the system is forced to exit the dirty blockage detection function.

[0104] Please combine Figure 3 An embodiment of the present invention provides a closed circulating water system 100, which includes a control component 44 and a water pump 14. The control component 44 is electrically connected to the water pump 14. The control component 44 includes a processor 46, a memory 48, and a computer program stored in the memory 48 and capable of running on the processor 46. When the computer program is executed by the processor 46, the steps of the dirt and blockage identification method of any of the above-mentioned embodiments are implemented.

[0105] In the above-mentioned closed circulating water system 100, when the first water pressure value of the closed circulating water system 100 is greater than or equal to the set water pressure threshold, the water pump 14 is controlled to operate with the set parameters and obtain the first water flow data. When the first water flow data is less than the set value, it can be determined that the system is blocked and a system blockage prompt message is output, so that the user can promptly discover the system blockage and improve the user experience.

[0106] The above explanation of the implementation and beneficial effects of the method for identifying dirt and blockage in the closed circulating water system 100 is also applicable to the closed circulating water system 100 of this embodiment, and will not be elaborated here to avoid redundancy.

[0107] In some embodiments, please combine Figure 4 The closed circulating water system 100 includes a first filter 40, a hydraulic module 24 and a hot water supply device. The hydraulic module 24 includes a buffer water tank 26, a hot water inlet connector 28 and a cold water outlet connector 30. The buffer water tank 26 includes a hot water connector 32 and a cold water connector 34. The water pump 14 is connected to the hot water connector 32 and the hot water inlet connector 28 respectively. The first filter 40 is connected to the cold water connector 34 and the cold water outlet connector 30 respectively. The hot water supply device is connected to the hot water inlet connector 28 and the cold water outlet connector 30 respectively.

[0108] In this way, the water pump 14 can deliver the hot water output by the hot water supply device to the buffer water tank 26 or the hot water device, and at the same time the first filter 40 can reduce impurities and sediments entering the hot water supply device, preventing blockage to a certain extent.

[0109] Specifically, in one embodiment, the closed-loop circulating water system 100 may be a heating unit. In one embodiment, the heating unit may include a hot water supply device, a hydraulic module 24, and a hot water consumption device. The hydraulic module 24 may be connected to the hot water supply device and the hot water consumption device via pipes. The hot water consumption device includes, but is not limited to, a domestic water tank, a zone one system, and a zone two system.

[0110] Optionally, the hot water supply device may include an air conditioning device, which may include a heat pump system. The air conditioning device may utilize the heat pump system to heat cold water into hot water and pass the hot water into the hydraulic module 24 through the hot water inlet connector 28 for distribution.

[0111] Optionally, the water supply device may include a gas boiler, which can use the heat generated by combustion of gas to heat cold water to produce hot water. The hot water output by the gas boiler is input into the hydraulic module 24 through the hot water inlet connector 28 for distribution.

[0112] Optionally, the hot water supply device includes a solar water heater, which is connected to the hot water inlet connector 28 via a pipeline. The solar water heater is used to heat water using solar energy to form hot water, which can be transmitted to the hydraulic module 24 for distribution.

[0113] Please combine Figure 4 In one embodiment, the water pump 14 can pump a portion of the hot water input from the hot water supply device through the hot water inlet connector 28 to the hot water outlet connector 50. The hot water outlet connector 50 can be connected to the hot water user device, and the hot water outlet connector 50 outputs the hot water to the hot water user device. Figure 4 In the illustrated embodiment, three hot water outlet connections 50 are provided: the upper hot water outlet connection 50 connects to the area 2 system, the middle hot water outlet connection 50 connects to the area 1 system, and the lower hot water outlet connection 50 connects to the domestic water tank. The remaining hot water supplied by the water heater via the hot water inlet connection 28 is pumped to the hot water connection 32, where it enters the buffer water tank 26 for storage.

[0114] In other embodiments, when the amount of hot water required by the water heater is large, all the hot water output by the water heater can flow into the water heater.

[0115] Hot water from the buffer water tank 26 is output to the hydraulic module 24 via the hot water connector 32. First, the hydraulic module 24 delivers the hot water via the hot water outlet connector 50 below to the coil within the domestic water tank. The hot water transfers heat through the coil to the domestic water in the tank, raising the temperature of the domestic water. The domestic water tank can be connected to a water outlet valve such as a faucet or showerhead, and the heated domestic water can be supplied to the user through the outlet valve.

[0116] Secondly, hydraulic module 24 can deliver hot water to the Zone 1 system via central hot water outlet connector 50. The Zone 1 system can include a heater suspended from the indoor ceiling, including but not limited to a fan coil unit (FCU). The FCU dissipates heat from the hot water into the room, raising the indoor temperature.

[0117] Thirdly, hydraulic module 24 can deliver hot water via hot water outlet connector 50 to the zone 2 system, which can include floor heating and / or radiators. The floor heating dissipates heat from the hot water to the floor, while the radiators dissipate heat from the hot water into the room, thereby raising the floor and indoor temperatures.

[0118] Please combine Figure 4Cold water from the buffer water tank 26 enters the hydraulic module 24 via the cold water connector 34. The cold water then flows through the first filter 40, where it is filtered. The filtered cold water is then output via the cold water outlet connector 30 to the hot water supply unit, where it is heated to form hot water. The hot water output from the hot water supply unit is then input into the hydraulic module 24 via the hot water inlet connector 28 and, via the hot water connector 32, enters the buffer water tank 26 for storage or is output to a hot water user. Because the cold water entering the hot water supply unit has been filtered by the first filter 40, impurities and sediment in the water flow are reduced, thereby reducing the risk of reduced operating efficiency due to wear or clogging of the hot water supply unit caused by impurities.

[0119] Optionally, in the embodiment of the present invention, the first filter 40 may include a magnetic filter. The magnetic filter can absorb metal and magnetic impurities in the water flow by using magnetic materials.

[0120] In some embodiments, the hydraulic module 24 includes a water pressure detection device 22 and a water flow detection device 20 , and the water pressure detection device 22 and the water flow detection device 20 are disposed upstream of the first filter 40 .

[0121] In this way, the area where the first filter 40 is located can be detected for dirt, so that the blockage of the hydraulic module 24 can be discovered in time.

[0122] Specifically, the cold water in the buffer water tank 26 can enter the hydraulic module 24 through the cold water connector 34. The water pressure detection device 22 and the water flow detection device 20 are arranged upstream of the second filter 42. The cold water will pass through the water pressure detection device 22 and the water flow detection device 20 and then flow through the first filter 40. The filtered cold water can be output from the cold water outlet connector 30 to the hot water supply device for heat exchange to form hot water.

[0123] When the closed-loop water system 100 is powered back on or the water pump 14 has been inactive for a period exceeding a set time threshold, the control component 44 can obtain a first water pressure value through the water pressure detection device 22. If the first water pressure value is greater than or equal to the set water pressure threshold, the control component 44 controls the water pump 14 to operate at the set parameters and obtains water flow data. After the water flow data stabilizes, the first water flow data is recorded. If the first water flow data is less than the set value, the control component 44 outputs a system blockage warning message, allowing the user to promptly detect system blockage and clean the first filter 40 to resolve the blockage.

[0124] In certain embodiments, the water heating device includes at least one of an air conditioning device, a gas furnace, and a solar water heater.

[0125] In this way, the source of hot water can be configured as needed.

[0126] Specifically, in one embodiment, the water supply device includes an air conditioner, a gas furnace, and a solar water heater. For example, when the closed-loop water circulation system 100 is operating in heating mode, if the ambient temperature is low and the air conditioner is inefficient, the gas furnace and / or solar water heater can be activated to produce hot water. If the solar water heater is inefficient due to insufficient light, the gas furnace and / or air conditioner can be activated to produce hot water. If there is no gas, the air conditioner and / or solar water heater can be activated to produce hot water.

[0127] In other embodiments, the water heating device includes any one or any two of an air conditioning device, a gas furnace, and a solar water heater.

[0128] In some embodiments, the hydraulic module 24 includes a first water supply connector 36 , and the closed circulating water system 100 includes a second filter 42 , which is connected to the first water supply connector 36 and the cold water outlet connector 30 .

[0129] In this way, the second filter 42 can filter impurities in the make-up water, thereby protecting the normal operation of the closed-loop circulating water system 100 to a certain extent.

[0130] Specifically, please combine Figure 1 Tap water (cold water) flows into the hydraulic module 24 through the first water supply connector 36. A second filter 42 is installed in the pipe between the first water supply connector 36 and the cold water outlet connector 30. The cold water flows through the second filter 42 and merges with the cold water output from the buffer water tank 26 through the cold water connector 34 before flowing out to the cold water outlet connector 30. The cold water then flows into the hot water supply device for heat exchange to produce hot water. Water contains calcium and magnesium ions. As the cold water flows, these ions form scale that adheres to the inner walls of the pipe, causing the pipe to narrow or even completely clog, affecting the normal operation of the hydraulic module 24.

[0131] Optionally, in this embodiment of the present invention, the second filter 42 may include a soft water filter. After the cold water passes through the soft water filter, the water quality is softened, which can effectively reduce the content of calcium and magnesium ions in the water, reduce the risk of pipe clogging due to scale, make the water flow smoother, and protect the normal operation of the hydraulic module 24 to a certain extent.

[0132] In some embodiments, the hydraulic module 24 includes a water pressure detection device 22 and a water flow detection device 20 , and the water pressure detection device 22 and the water flow detection device 20 are disposed upstream of the second filter 42 .

[0133] In this way, the area where the second filter 42 is located can be detected for dirt, so that the blockage of the hydraulic module 24 can be discovered in time.

[0134] Specifically, tap water (cold water) flows into the hydraulic module 24 through the first water supply joint 36. The water pressure detection device 22 and the water flow detection device 20 are arranged upstream of the second filter 42. The cold water will pass through the water pressure detection device 22 and the water flow detection device 20 and then flow through the second filter 42. It will merge with the cold water output from the buffer water tank 26 through the cold water joint 34 and then flow out to the cold water outlet joint 30, so that the cold water flows into the hot water supply device for heat exchange to form hot water.

[0135] When the closed-loop water system 100 is powered back on or the water pump 14 has been inactive for a period exceeding a set time threshold, the control component 44 can obtain a first water pressure value through the water pressure detection device 22. If the first water pressure value is greater than or equal to the set water pressure threshold, the control component 44 controls the water pump 14 to operate at the set parameters and obtains water flow data. After the water flow data stabilizes, the first water flow data is recorded. If the first water flow data is less than the set value, the control component 44 outputs a system blockage warning message, allowing the user to promptly detect system blockage and clean the second filter 42 to resolve the blockage.

[0136] An embodiment of the present invention provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by the processor 46 , the steps of the dirt blockage identification method of any of the above embodiments are implemented.

[0137] For example, the control method implemented when the computer program is executed by the processor 46 includes:

[0138] S01, obtaining a first water pressure value of the closed circulating water system 100;

[0139] S03, when the first water pressure value is greater than or equal to the set water pressure threshold, controlling the water pump 14 to operate with set parameters and obtaining water flow data;

[0140] S05, after the water flow data is stable, recording the first water flow data;

[0141] S07: When the first water flow rate data is less than a set value, output a system dirty and blocked prompt message.

[0142] It should be noted that the above-mentioned method for identifying dirt and blockage in the closed circulating water system 100 and the explanation and beneficial effects of the implementation of the closed circulating water system 100 are also applicable to the computer-readable storage medium of the implementation of the present invention. To avoid redundancy, they will not be elaborated here.
