Description

Technical Field

[0001] This invention relates to the field of drinking water equipment technology, and in particular to a water circulation control method and device applied to drinking water equipment. Background Technology

[0002] Currently, after water dispensers (such as kettles) have heated the water needed for drinking, the drinking water usually needs to be cooled. The existing cooling method is mainly to cool the water in the water dispenser (such as a kettle) through cooling pipes installed on the side wall of the water dispenser.

[0003] However, in practice, it has been found that the water cooled in the cooling pipes is usually discharged into the sewer system, which wastes water resources. Therefore, proposing a new water circulation control scheme to reduce water waste is particularly important. Summary of the Invention

[0007] Determine whether the water quality information meets the preset water quality conditions;

[0008] When it is determined that the water quality information meets the water quality conditions, the cooling water is identified as the next heating target of the drinking water equipment.

[0094] This invention discloses a water circulation control method and apparatus for drinking water equipment. It can detect the water quality information of the cooling water in the cooling pipes of the drinking water equipment and determine whether the water quality information meets preset water quality conditions. Only when the water quality conditions are met is the cooling water determined to be the next heating target of the drinking water equipment.

Detailed descriptions follow.

[0095] To better understand the water circulation control method and apparatus for drinking water equipment described in this invention, the applicable household scenario for the water circulation control method for drinking water equipment is first described. Specifically, a schematic diagram of this household scenario can be shown as follows: Figure 1 As shown, Figure 1 This is a schematic diagram illustrating a scenario applicable to a water circulation control method for drinking water equipment disclosed in an embodiment of the present invention, such as...

[0097] Example 1

[0098] Please see Figure 2 , Figure 2 This is a schematic flowchart of a water circulation control method for drinking water equipment disclosed in an embodiment of the present invention. Figure 2 The described water circulation control method for drinking water equipment can be applied to a water circulation control device, which may include a control device or a control server. The control server may include a cloud server or a local server; this embodiment of the invention is not limited to any particular type. Figure 2As shown, the water circulation control method applied to drinking water equipment may include the following operations:

[0099] 101. Inspect the water quality information of the cooling water in the cooling pipes contained in the drinking water equipment.

[0100] In this embodiment of the invention, optionally, the cooling pipe is installed in the side wall of the water drinking device, and the inlet of the cooling pipe is connected to a faucet. When it is necessary to perform a cooling operation on the water drinking device for drinking water, the valve between the faucet and the inlet of the cooling pipe can be opened so that the faucet can input cold water (the cold water is the cooling water mentioned above) into the cooling pipe.

[0101] In this embodiment of the invention, the cooling water can be used to cool the hot water in the drinking water equipment. Optionally, the water quality information of the cooling water may include one or more combinations of the turbidity, transparency, and pH value of the cooling water.

[0102] 102. Determine whether the water quality information meets the preset water quality conditions.

[0103] In this embodiment of the invention, the preset water quality conditions can be conditions corresponding to Class I drinking water, conditions corresponding to Class II drinking water, or other pre-set judgment conditions. This embodiment of the invention does not limit these conditions.

[0104] In this embodiment of the invention, when the judgment result of step 102 is yes (i.e., the water quality information meets the water quality conditions), step 103 is triggered; when the judgment result of step 102 is no, the process can be terminated.

[0105] 103. The cooling water will be designated as the next heating source for the drinking water equipment.

[0106] In this embodiment of the invention, specifically, when the water dispenser performs the next water heating operation, the aforementioned cooling water, which is the target for the next heating, is input into the water dispenser so that the water dispenser heats the input cooling water. Specifically, a connection can be established between the outlet of the cooling pipe and the inlet of the water dispenser, so that the cooling water flows into the water dispenser through the outlet of the cooling pipe and is heated by the water dispenser.

[0107] It is evident that implementation Figure 2The described water circulation control method for drinking water equipment can detect the water quality information of the cooling water in the cooling pipes of the drinking water equipment and determine whether the water quality information meets the preset water quality conditions. Only when the water quality conditions are met is the cooling water determined to be the next heating target of the drinking water equipment. Based on the water quality information of the cooling water, the accuracy of determining the purpose of the cooling water can be improved, which is conducive to realizing the recycling of cooling water and thus reducing water waste. It also helps to reduce the occurrence of subsequent heating of cooling water that does not need to be heated by the drinking water equipment due to judgment errors, which is conducive to improving the water quality of drinking water in the drinking water equipment and improving the health of users in terms of drinking water.

[0108] In an optional embodiment, the method may further include:

[0109] When it is determined that the water quality information does not meet the water quality conditions, the real-time water demand of the scene where the drinking water equipment is located is obtained;

[0110] Determine the target use of cooling water based on real-time water demand;

[0111] Depending on the intended use, the outlet of the cooling pipe is connected to the target pipeline that matches the intended use, so that cooling water flows from the outlet of the cooling pipe into the target pipeline.

[0112] In this embodiment of the invention, optionally, real-time water demand may include watering demand and / or handwashing demand. Watering demand may include the need to water potted plants in the scene where the water dispenser is located, and handwashing demand may include the need for users in the scene where the water dispenser is located to wash their hands; this embodiment of the invention does not impose limitations on these aspects.

[0113] Specifically, determining the target use of cooling water based on real-time water demand can include: when real-time water demand only includes watering, the target use of cooling water is determined to be watering; when real-time water demand only includes handwashing, the target use of cooling water is determined to be handwashing; when real-time water demand includes both watering and handwashing, the length of the first pipe between the user's handwashing pipe and the cooling pipe, and the length of the second pipe between the user's watering pipe and the cooling pipe are detected. Based on the lengths of the first and second pipes, one of the watering and handwashing demands is selected as the target water demand, and the target use of cooling water is determined to be the use corresponding to the target water demand. For example, if the length of the first pipe is less than the length of the second pipe, then the handwashing demand is determined as the target water demand, and the corresponding use is handwashing; if the length of the first pipe is greater than the length of the second pipe, then the watering demand is determined as the target water demand, and the corresponding use is watering; if the length of the first pipe is equal to the length of the second pipe, then one of the handwashing and watering demands can be randomly selected as the target water demand. This allows for improved accuracy and reliability in determining the use of cooling water based on real-time water demand, and also enables greater diversity in the use of cooling water based on diverse real-time water demand.

[0114] As can be seen, this optional embodiment can obtain the real-time water demand of the drinking water equipment scene when it is determined that the water quality information does not meet the water quality conditions, and determine the target use of the cooling water based on the real-time water demand. This can improve the accuracy of the target use determination. Subsequently, based on the accurately determined target use, the outlet of the cooling pipe is connected to the target pipe that matches the target use. This can improve the control accuracy of the connection between the outlet of the cooling pipe and the target pipe, which is beneficial for the subsequent flow of cooling water through the outlet of the cooling pipe to the target pipe, thereby facilitating the full utilization of cooling water through the target pipe.

[0131] In this embodiment of the invention, after the hot water cooling operation in step 208 is completed, step 204 is triggered.

[0132] It is evident that implementation Figure 3The described water circulation control method for drinking water equipment can detect the water quality information of the cooling water in the cooling pipes of the drinking water equipment and determine whether the water quality information meets the preset water quality conditions. Only when the water quality conditions are met is the cooling water determined to be the next heating target of the drinking water equipment. Based on the water quality information of the cooling water, the accuracy of determining the purpose of the cooling water can be improved, which is conducive to realizing the recycling of cooling water and thus reducing water waste. It also helps to reduce the occurrence of subsequent heating of cooling water that does not need to be heated by the drinking water equipment due to judgment errors, which is conducive to improving the water quality of drinking water in the drinking water equipment and improving the health of users in terms of drinking water. Furthermore, it can acquire relevant parameters of the hot water based on the user's drinking habits (including the user's preferred drinking time and preferred drinking temperature) and the hot water contained in the drinking water device. Based on the hot water temperature, it predicts the natural cooling temperature of the hot water after a certain natural cooling time. Then, it determines whether the natural cooling temperature of the hot water is lower than or equal to the drinking water temperature. If it is determined to be lower than or equal to the drinking water temperature, it directly triggers the execution of step 204. If it is determined to be higher than the drinking water temperature, it first controls the opening of the valves of the cooling pipe and the faucet, improving the accuracy of the valve opening control. Then, it controls the cooling water to cool the hot water, improving the accuracy of the cooling water to cool the hot water control. Only after cooling is completed is step 204 triggered. It can improve the diversity and flexibility of the preconditions for detecting the water quality information of the cooling water based on the natural cooling temperature, thereby helping to improve the accuracy and reliability of water quality information detection.

[0133] In an optional embodiment, after step 208 above, whereby the cooling water supplied to the cooling pipe via a faucet performs a hot water cooling operation, the method may further include:

[0134] During the hot water cooling operation, based on the relevant parameters of the hot water, it is determined whether the hot water meets the preset cooling completion conditions, and the hot water judgment result is obtained.

[0135] When the hot water determination result is that the hot water does not meet the cooling completion condition, the time required for the hot water to meet the cooling completion condition is predicted based on the hot water's relevant parameters, and this is taken as the expected cooling completion time. After the expected cooling completion time, the above-mentioned operation of determining whether the hot water meets the preset cooling completion condition based on the hot water's relevant parameters is triggered to obtain the hot water determination result, until the hot water meets the cooling completion condition.

[0136] When the hot water determination result indicates that the hot water meets the cooling completion conditions, the hot water cooling operation is considered to have been completed.

[0137] In this embodiment of the invention, the hot water determination result includes the result that the hot water meets the preset cooling completion conditions, or the result that the hot water does not meet the preset cooling completion conditions. The cooling completion conditions may include temperature compliance conditions, or conditions corresponding to cooling time; this embodiment of the invention does not impose any limitations.

[0138] As can be seen, this optional embodiment can determine whether the hot water meets the preset cooling completion conditions based on the hot water's relevant parameters during the hot water cooling operation, obtain the hot water judgment result, and predict the time required for the hot water to meet the cooling completion conditions based on the hot water's relevant parameters when the hot water does not meet the cooling completion conditions. This prediction is used as the expected cooling completion time, which improves the accuracy of the expected cooling completion time prediction when the hot water does not meet the cooling completion conditions. Subsequently, after the expected cooling completion time, the operation of determining whether the hot water meets the preset cooling completion conditions based on the hot water's relevant parameters and obtaining the hot water judgment result is triggered until the hot water meets the cooling completion conditions. This improves the accuracy of determining the judgment time required for the hot water to meet the preset cooling completion conditions. Furthermore, when the hot water meets the cooling completion conditions, the hot water cooling operation is directly determined to be completed, which improves the speed and efficiency of determining the completion of the hot water cooling operation when the hot water meets the cooling completion conditions. Based on the hot water judgment result, the accuracy and flexibility of determining whether the hot water cooling operation has been completed are improved.

[0139] In this optional embodiment, as an optional implementation, the above-mentioned prediction of the time required for the hot water to meet the cooling completion conditions based on the hot water-related parameters, as the expected cooling completion time of the hot water, may include:

[0140] Obtain information on the flow of target cooling water in the cooling pipes;

[0141] Based on the flow of the target cooling water in the cooling pipe, the residence time of the target cooling water in the cooling pipe is predicted and used as the expected residence time of the target cooling water.

[0142] Based on the hot water temperature, the expected residence time of the target cooling water, and the obtained cold water temperature of the target cooling water, predict the temperature change trend of the hot water.

[0143] Based on the temperature change trend of the hot water, the time required for the hot water to meet the cooling completion conditions is predicted and used as the expected cooling completion time of the hot water.

[0144] In this embodiment of the invention, the target cooling water is the cooling water input into the cooling pipe at a certain moment. Optionally, the flow of the target cooling water in the cooling pipe includes the real-time volume of the target cooling water in the cooling pipe and / or the flow rate of the target cooling water in the cooling pipe. The starting time of the expected residence time of the target cooling water is a certain moment. The cold water temperature of the target cooling water includes the temperature of the target cooling water at the moment it is input from the tap into the cooling pipe, which is not limited in this embodiment of the invention.

[0145] In this embodiment of the invention, the temperature change trend can be used to represent the temperature-time correspondence. Specifically, based on the temperature-time correspondence represented by the hot water temperature change trend, the required cooling completion temperature and the cooling completion time at which the aforementioned cooling completion conditions are met are found from the temperature-time correspondence. Using one of these times as the start time and the cooling completion time as the end time, the expected cooling completion time of the target cooling water is predicted. This improves the accuracy and reliability of predicting the expected cooling completion time based on the temperature change trend.

[0146] As can be seen, this optional implementation can obtain the flow of the target cooling water in the cooling pipe, and predict the residence time of the target cooling water in the cooling pipe based on the flow of the target cooling water, as the expected residence time of the target cooling water. This can improve the prediction accuracy of the expected residence time of the target cooling water based on the flow of the target cooling water. Subsequently, based on the hot water temperature, the accurately predicted expected residence time, and the obtained cold water temperature of the target cooling water, the temperature change trend of the hot water can be predicted, which can improve the prediction accuracy of the temperature change trend of the hot water. Then, based on the accurately predicted temperature change trend, the time required for the hot water to meet the cooling completion conditions can be predicted, as the expected cooling completion time of the hot water. This can improve the prediction accuracy of the expected cooling completion time to a certain extent, thereby helping to improve the accuracy and reliability of determining the trigger time of subsequent judgment on whether the hot water meets the preset cooling completion conditions based on the accurately predicted expected cooling completion time.

[0147] In this optional embodiment, as another optional implementation, the aforementioned hot water-related parameters may further include the current cooling time of the hot water, which is the cooling time already elapsed when the hot water cooling operation is currently performed. Furthermore, the aforementioned determination of whether the hot water meets the preset cooling completion conditions based on the hot water-related parameters to obtain the hot water determination result may include:

[0148] Based on the hot water temperature, determine whether the hot water meets the preset temperature standard.

[0149] When it is determined that the hot water meets the temperature standard, the hot water meets the preset cooling completion condition.

[0150] When it is determined that the hot water does not meet the temperature requirement, it is determined that the hot water does not meet the preset cooling completion condition; or,

[0151] When it is determined that the hot water does not meet the temperature standard, the hot water judgment result is determined based on the current cooling time of the hot water.

[0152] It should be noted that the current cooling time is less than the cooling completion time. Optionally, the temperature target conditions can include conditions where the hot water temperature is lower than the preset temperature.

[0153] As can be seen, this optional implementation can determine whether the hot water meets the preset temperature standard based on the hot water temperature. If the hot water meets the temperature standard, it can directly determine that the hot water meets the cooling completion condition, thus improving the efficiency and speed of determining whether the hot water meets the cooling completion condition. If the hot water does not meet the temperature standard, it can directly determine that the hot water does not meet the cooling completion condition, thus improving the efficiency and speed of determining whether the hot water does not meet the cooling completion condition. It can also determine whether the hot water meets the cooling completion condition based on the current cooling time, thus improving the accuracy and reliability of determining whether the hot water meets the cooling completion condition to a certain extent. Furthermore, it can increase the diversity and flexibility of the determination method based on the hot water temperature and the current cooling time.

[0154] In this optional implementation, the above-mentioned determination of whether the hot water meets the preset temperature standard based on the hot water temperature may include:

[0155] Determine if the hot water temperature is lower than or equal to the preset temperature;

[0156] When it is determined that the hot water temperature is lower than or equal to the preset temperature, the hot water meets the preset temperature standard.

[0157] When it is determined that the hot water temperature is higher than the preset temperature, it is determined that the hot water does not meet the preset temperature standard.

[0158] In this embodiment of the invention, optionally, the preset temperature can be the drinking water temperature that the user is accustomed to, or it can be any other temperature corresponding to any value set by the user. This embodiment of the invention does not impose any limitations.

[0159] As can be seen, this optional implementation can also determine whether the hot water temperature is lower than or equal to the preset temperature, and only when the hot water temperature is determined to be lower than or equal to the preset temperature is it determined that the hot water meets the temperature standard conditions, thereby improving the accuracy and reliability of determining whether the hot water meets the temperature standard conditions. This is conducive to improving the accuracy of determining whether the hot water meets the cooling completion conditions in the subsequent process. Furthermore, only when the hot water temperature is determined to be higher than the preset temperature is it determined that the hot water does not meet the temperature standard conditions, thereby improving the accuracy and reliability of determining whether the hot water does not meet the temperature standard conditions.

[0160] In this optional implementation, the process of determining the hot water judgment result based on the current cooling time of the hot water may include:

[0161] Determine whether the current cooling time of the hot water is greater than or equal to the preset cooling time;

[0162] When it is determined that the current cooling time of the hot water is greater than or equal to the preset cooling time, the hot water is determined to meet the cooling completion condition.

[0163] If it is determined that the current cooling time of the hot water is less than the preset cooling time, it is determined that the hot water does not meet the cooling completion condition.

[0164] In this embodiment of the invention, the preset cooling time can be 2 minutes, 5 minutes, or any other pre-set value; this embodiment of the invention does not impose any limitations.

[0165] As can be seen, this optional implementation can further determine whether the current cooling time of the hot water is greater than or equal to the preset cooling time when it is determined that the current cooling time of the hot water is greater than or equal to the preset cooling time. If it is determined that the current cooling time of the hot water is greater than or equal to the preset cooling time, it can determine that the hot water meets the cooling completion condition, which improves the accuracy and reliability of determining that the hot water meets the cooling completion condition to a certain extent. And if it is determined that the current cooling time is less than the preset cooling time, it can determine that the hot water does not meet the cooling completion condition, which improves the accuracy and reliability of determining that the hot water does not meet the cooling completion condition to a certain extent.

[0167] Please see Figure 4 , Figure 4 This is a schematic diagram of a water circulation control device for drinking water equipment disclosed in an embodiment of the present invention. Figure 4 The described water circulation control device for drinking water equipment may include control equipment or a control server, wherein the control server may include a cloud server or a local server, and the embodiments of the present invention are not limited thereto. Figure 4 As shown, the water circulation control device applied to drinking water equipment may include:

[0168] The detection module 301 is used to detect the water quality information of the cooling water in the cooling pipes contained in the drinking water equipment. The cooling water is used to cool the hot water in the drinking water equipment.

[0169] The judgment module 302 is used to determine whether the water quality information meets the preset water quality conditions.

[0170] The determination module 303 is used to determine the cooling water as the next heating object of the drinking water equipment when the judgment module 302 determines that the water quality information meets the water quality conditions.

[0171] It is evident that implementation Figure 4 The described water circulation control device for drinking water equipment can detect the water quality information of the cooling water in the cooling pipes of the drinking water equipment and determine whether the water quality information meets the preset water quality conditions. Only when the water quality conditions are met is the cooling water determined to be the next heating target of the drinking water equipment. Based on the water quality information of the cooling water, the accuracy of determining the purpose of the cooling water can be improved, which is conducive to realizing the recycling of cooling water and thus reducing water waste. It also helps to reduce the occurrence of subsequent heating of cooling water that does not need to be heated by the drinking water equipment due to misjudgment, which is conducive to improving the water quality of drinking water in the drinking water equipment and improving the health of users in terms of drinking water.

[0172] In an optional embodiment, such as Figure 5 As shown, Figure 5 This is a schematic diagram of another water circulation control device for drinking water equipment disclosed in an embodiment of the present invention, wherein, as shown... Figure 5 As shown, the device may further include:

[0173] The first acquisition module 304 is used to acquire hot water-related parameters based on the user's drinking habits and the hot water contained in the drinking water device before the detection module 301 detects the water quality information of the cooling water in the cooling pipe contained in the drinking water device. The drinking habits include the user's usual drinking time and the user's usual drinking temperature, and the hot water-related parameters include the hot water temperature.

[0174] The prediction module 305 is used to predict the natural cooling temperature of the hot water after a calculated natural cooling time, based on the hot water temperature. The start time of the natural cooling time is the current time, and the end time of the natural cooling time is the drinking time.

[0175] The judgment module 302 is also used to determine whether the natural cooling temperature of the hot water is lower than or equal to the drinking water temperature; when it is determined that the natural cooling temperature of the hot water is lower than or equal to the drinking water temperature, the detection module 301 is triggered to perform the above-mentioned operation of detecting the water quality information of the cooling water in the cooling pipe contained in the drinking water device.

[0176] The first control module 306 is used to control the valve between the cooling pipe and the faucet to open when the judgment module 302 determines that the natural cooling temperature of the hot water is higher than the drinking water temperature, and to control the cooling water input into the cooling pipe through the faucet to perform a hot water cooling operation on the hot water. After the hot water cooling operation is completed, the detection module 301 is triggered to perform the above-mentioned operation of detecting the water quality information of the cooling water in the cooling pipe included in the drinking water device.

[0177] It is evident that implementation Figure 5 The described device can also acquire hot water-related parameters based on the user's drinking habits (including the user's preferred drinking time and preferred drinking temperature) and the hot water contained in the drinking water device. Based on the hot water temperature, it predicts the natural cooling temperature of the hot water after a certain natural cooling time. Then, it determines whether the natural cooling temperature of the hot water is lower than or equal to the drinking water temperature. If it is determined to be lower than or equal to the drinking water temperature, step 204 is directly triggered. If it is determined to be higher than the drinking water temperature, the device first controls the opening of the valves of the cooling pipe and the faucet, improving the accuracy of valve opening control. Then, it controls the cooling water to cool the hot water, improving the accuracy of cooling water control. Only after cooling is complete is step 204 triggered. This allows for greater diversity and flexibility in the preconditions for detecting water quality information of the cooling water based on the natural cooling temperature, thereby improving the accuracy and reliability of water quality information detection.

[0178] In this optional embodiment, as an optional implementation method, the judgment module 302 is further configured to, after the first control module 306 controls the cooling water input through the faucet to perform a hot water cooling operation on the hot water, determine whether the hot water meets the preset cooling completion conditions based on the hot water-related parameters during the hot water cooling operation, and obtain the hot water judgment result.

[0179] The prediction module 305 is also used to predict the time required for the hot water to meet the cooling completion conditions based on the hot water-related parameters of the hot water when the hot water judgment result of the judgment module 302 is that the hot water does not meet the cooling completion conditions, as the expected cooling completion time of the hot water; and after the expected cooling completion time, trigger the judgment module 302 to perform the above-mentioned operation of judging whether the hot water meets the preset cooling completion conditions based on the hot water-related parameters of the hot water and obtaining the hot water judgment result, until the hot water meets the cooling completion conditions.

[0180] The determination module 303 is also used to determine that the hot water cooling operation has been completed when the hot water determination result of the judgment module 302 is that the hot water meets the cooling completion condition.

[0181] As can be seen, this optional implementation can determine whether the hot water meets the preset cooling completion conditions based on the hot water's relevant parameters during the hot water cooling operation, obtain the hot water judgment result, and predict the time required for the hot water to meet the cooling completion conditions based on the hot water's relevant parameters when the hot water does not meet the cooling completion conditions. This prediction is used as the expected cooling completion time, which improves the accuracy of the expected cooling completion time prediction when the hot water does not meet the cooling completion conditions. Subsequently, after the expected cooling completion time, the operation of determining whether the hot water meets the preset cooling completion conditions based on the hot water's relevant parameters and obtaining the hot water judgment result is triggered until the hot water meets the cooling completion conditions. This improves the accuracy of determining the time required for the hot water to meet the preset cooling completion conditions. Furthermore, when the hot water meets the cooling completion conditions, the hot water cooling operation is directly determined to be completed, which improves the speed and efficiency of determining the completion of the hot water cooling operation when the hot water meets the cooling completion conditions. Based on the hot water judgment result, the accuracy and flexibility of determining whether the hot water cooling operation has been completed are improved.

[0182] In this optional implementation, the prediction module may, based on the hot water's relevant parameters, predict the time required for the hot water to meet the cooling completion conditions. Specifically, the method for determining the expected cooling completion time of the hot water may include:

[0183] The flow of the target cooling water in the cooling pipe is obtained. The target cooling water is the cooling water input into the cooling pipe at a certain moment. The flow includes the real-time volume of the target cooling water in the cooling pipe and / or the flow rate of the target cooling water in the cooling pipe.

[0184] Based on the flow of the target cooling water in the cooling pipe, the residence time of the target cooling water in the cooling pipe is predicted as the expected residence time of the target cooling water, and the starting time of the expected residence time is a certain moment.

[0185] Based on the hot water temperature, the expected residence time of the target cooling water, and the obtained cold water temperature of the target cooling water, the temperature change trend of the hot water is predicted. The temperature change trend is used to represent the temperature-time correspondence.

[0186] Based on the temperature change trend of the hot water, the time required for the hot water to meet the cooling completion conditions is predicted and used as the expected cooling completion time of the hot water.

[0187] As can be seen, this optional implementation can also acquire the flow of the target cooling water in the cooling pipe, and predict the residence time of the target cooling water in the cooling pipe based on the flow of the target cooling water in the cooling pipe, as the expected residence time of the target cooling water. This can improve the prediction accuracy of the expected residence time of the target cooling water based on the flow of the target cooling water. Subsequently, based on the hot water temperature, the accurately predicted expected residence time, and the acquired cold water temperature of the target cooling water, the temperature change trend of the hot water can be predicted, which can improve the prediction accuracy of the temperature change trend of the hot water. Then, based on the accurately predicted temperature change trend, the time required for the hot water to meet the cooling completion conditions can be predicted, as the expected cooling completion time of the hot water. This can improve the prediction accuracy of the expected cooling completion time to a certain extent, thereby helping to improve the accuracy and reliability of determining the trigger time for subsequent judgments on whether the hot water meets the preset cooling completion conditions based on the accurately predicted expected cooling completion time.

[0188] In this optional implementation, the hot water-related parameters may also include the current cooling time of the hot water, which is the cooling time already elapsed when the hot water cooling operation is performed. Furthermore, the judgment module 302 determines whether the hot water meets the preset cooling completion conditions based on the hot water-related parameters, and the specific method for obtaining the hot water judgment result may include:

[0189] Based on the hot water temperature, determine whether the hot water meets the preset temperature standard.

[0190] When it is determined that the hot water meets the temperature standard, the hot water meets the preset cooling completion condition.

[0191] When it is determined that the hot water does not meet the temperature requirement, it is determined that the hot water does not meet the preset cooling completion condition; or,

[0192] When it is determined that the hot water does not meet the temperature standard, the hot water judgment result is determined based on the current cooling time of the hot water.

[0193] As can be seen, this optional implementation can also determine whether the hot water meets the preset temperature standard based on the hot water temperature. If the hot water meets the temperature standard, it can directly determine that the hot water meets the cooling completion condition, thus improving the efficiency and speed of determining whether the hot water meets the cooling completion condition. If the hot water does not meet the temperature standard, it can directly determine that the hot water does not meet the cooling completion condition, thus improving the efficiency and speed of determining whether the hot water does not meet the cooling completion condition. It can also determine whether the hot water meets the cooling completion condition based on the current cooling time, thus improving the accuracy and reliability of determining whether the hot water meets the cooling completion condition to a certain extent. Furthermore, it can increase the diversity and flexibility of the determination method based on the hot water temperature and the current cooling time.

[0194] In this optional implementation, the method by which the judging module 302 judges whether the hot water meets the preset temperature standard based on the hot water temperature may specifically include:

[0195] Determine if the hot water temperature is lower than or equal to the preset temperature;

[0196] When it is determined that the hot water temperature is lower than or equal to the preset temperature, the hot water meets the preset temperature standard.

[0197] When it is determined that the hot water temperature is higher than the preset temperature, it is determined that the hot water does not meet the preset temperature standard.

[0198] As can be seen, this optional implementation can also determine whether the hot water temperature is lower than or equal to the preset temperature, and only when the hot water temperature is determined to be lower than or equal to the preset temperature is it determined that the hot water meets the temperature standard conditions, thereby improving the accuracy and reliability of determining whether the hot water meets the temperature standard conditions. This is conducive to improving the accuracy of determining whether the hot water meets the cooling completion conditions in the subsequent process. Furthermore, only when the hot water temperature is determined to be higher than the preset temperature is it determined that the hot water does not meet the temperature standard conditions, thereby improving the accuracy and reliability of determining whether the hot water does not meet the temperature standard conditions.

[0199] In this optional implementation, the method by which the determining module 302 determines the hot water determination result based on the current cooling time of the hot water may specifically include:

[0200] Determine whether the current cooling time of the hot water is greater than or equal to the preset cooling time;

[0201] When it is determined that the current cooling time of the hot water is greater than or equal to the preset cooling time, the hot water is determined to meet the cooling completion condition.

[0202] If it is determined that the current cooling time of the hot water is less than the preset cooling time, it is determined that the hot water does not meet the cooling completion condition.

[0203] As can be seen, this optional implementation can further determine whether the current cooling time of the hot water is greater than or equal to the preset cooling time when it is determined that the current cooling time of the hot water is greater than or equal to the preset cooling time. If it is determined that the current cooling time of the hot water is greater than or equal to the preset cooling time, it can determine that the hot water meets the cooling completion condition, which improves the accuracy and reliability of determining that the hot water meets the cooling completion condition to a certain extent. And if it is determined that the current cooling time is less than the preset cooling time, it can determine that the hot water does not meet the cooling completion condition, which improves the accuracy and reliability of determining that the hot water does not meet the cooling completion condition to a certain extent.

[0204] In another alternative embodiment, such as Figure 5 As shown, the device may further include:

[0205] The second acquisition module 307 is used to acquire the real-time water demand of the scene where the drinking water equipment is located when the judgment module 302 determines that the water quality information does not meet the water quality conditions.

[0206] The determination module 303 is also used to determine the target use of cooling water based on real-time water demand.

[0207] The second control module 308 is used to control the connection between the outlet of the cooling pipe and the target pipe that matches the target application, so that the cooling water flows from the outlet of the cooling pipe into the target pipe.

[0208] As can be seen, this optional embodiment can detect the water quality information of the cooling water in the cooling pipe included in the drinking water device, and determine whether the water quality information meets the preset water quality conditions. Only when the water quality conditions are met is the cooling water determined to be the next heating target of the drinking water device. Based on the water quality information of the cooling water, the accuracy of determining the use of the cooling water can be improved, which is conducive to realizing the recycling of cooling water and thus reducing the waste of water resources. It also helps to reduce the occurrence of subsequent heating of cooling water that does not need to be heated by the drinking water device due to judgment errors, which is conducive to improving the water quality of drinking water in the drinking water device and improving the health of users in terms of drinking water.
