[0002] As people's requirements for drinking water quality increase, household water purifiers are becoming increasingly popular. Among them, under-sink direct drinking water purifiers are widely welcomed due to their convenient installation and large water flow rate. To solve the problem of hot and cold water mixing, under-sink direct drinking water equipment is usually designed with a dual-pipeline structure, used to output hot water and room temperature water respectively.

[0003] However, in practical use, when a user continuously uses one pipe (such as a room temperature water pipe) for an extended period, another pipe (such as a hot water pipe) is prone to stagnant water due to prolonged lack of circulation. Stagnant water not only produces an unpleasant odor but may also breed bacteria, affecting water quality and posing a potential threat to the user's health. Existing methods are insufficient to prevent stagnant water from forming in another pipe when a user continuously uses one pipe. Summary of the Invention

[0041] Control component-110; First solenoid valve-120; Second solenoid valve-130; Heating component-140; First water outlet channel-210; Second water outlet channel-220; Water outlet-230; Purification system-300. Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] In related technologies, as residents' requirements for drinking water quality increase, household water purification equipment (such as under-sink direct drinking water purifiers and water dispensers) has become a standard feature in homes. To avoid the mixing of hot and cold water affecting the water temperature and user experience, these devices generally adopt a dual-pipeline structure. For example, one pipeline is the first outlet channel (outputting room temperature water), and the other is the second outlet channel (which, in conjunction with the heating element, outputs hot water).

[0044] However, existing dual-pipeline drinking water systems have significant technical drawbacks. When a user uses one pipe (such as the ambient temperature water channel) for an extended period, the water in the other pipe (such as the hot water channel) will become stagnant due to prolonged standing. Stagnant water not only easily produces odors but may also breed bacteria, posing a potential threat to the user's health. Current technology relies solely on manual switching or periodic flushing by the user, which is cumbersome and cannot prevent stagnant water problems in real time. Some systems employ periodic forced flushing, requiring the discharge of a certain amount of water regardless of whether stagnant water exists in the pipes, leading to water waste. Furthermore, frequent flushing increases the number of times solenoid valves and heating components are started and stopped, shortening the equipment's lifespan.

[0045] To address the aforementioned issues, there is an urgent need for a water control solution that can meet users' normal water usage needs while also considering the removal of stagnant water, resource conservation, and equipment protection.

[0046] In one embodiment, such as Figure 1 and Figure 2 As shown, a drinking water device and a water circuit control system are provided. The drinking water device includes a first water outlet channel 210, a second water outlet channel 220, a water outlet 230, a purification system 300, and a water circuit control system. The water circuit control system includes a control component 110, a first solenoid valve 120, a second solenoid valve 130, and a heating component 140.

[0047] In this embodiment, the purification system 300 is used to purify tap water, raw water, or untreated water to obtain drinking water that meets the user's direct drinking requirements. This embodiment does not limit the water intake of the purification system 300; it can be determined based on the type and configuration of the purification equipment in the actual application scenario. The purification process includes, but is not limited to, filtration and disinfection. Direct drinking requirements mean that the water dispensed from the water outlet 230 of the drinking water device is suitable for direct consumption by the user.

[0048] One end of the first water outlet channel 210 is connected to the first water outlet of the purification system 300, and the other end of the first water outlet channel 210 is connected to the water outlet 230 of the drinking water device. The first water outlet channel 210 of the second water outlet channel 220 is connected to the second water outlet of the purification system 300, and the other end of the second water outlet channel 220 is connected to the water outlet 230 of the drinking water device. In this embodiment, the first water outlet channel 210 is used to receive and deliver room temperature drinking water. The second water outlet channel 220 is used to receive and deliver high temperature drinking water. It should be noted that the first water outlet of the purification system 300 is used to output room temperature drinking water, and the second water outlet is used to output either room temperature or high temperature drinking water. The high temperature water delivered through the second water outlet channel is obtained by heating the water through the heating element in the purification system 300 and the heating component 140 in the water circuit control system. It should be noted that this embodiment does not limit the specific structure of the purification system 300, and it can be configured according to the needs of the actual application scenario.

[0049] In this embodiment, as Figure 2As shown, a first solenoid valve 120 is disposed within the first water outlet channel 210, and a second solenoid valve 130 and a heating assembly 140 are disposed within the second water outlet channel 220. The first solenoid valve 120 is positioned within the first water outlet channel 210 near the first water outlet end of the purification system 300, and is used to control the water flow within the first water outlet channel 210. The second solenoid valve 130 is positioned within the second water outlet channel 220 near the second water outlet end of the purification system 300, and is used to control the water flow within the second water outlet channel 220. In a specific embodiment, when the first solenoid valve 120 is open, water output from the first water outlet end of the purification system 300 can flow through the first water outlet channel 210 to the water outlet 230. When the first solenoid valve 120 is closed, water output from the first water outlet end of the purification system 300 cannot flow through the first water outlet channel 210 to the water outlet 230. When the second solenoid valve 130 is open, water output from the second water outlet end of the purification system 300 can flow through the second water outlet channel 220 to the water outlet 230. When the second solenoid valve 130 is closed, the water output from the second outlet of the purification system 300 cannot flow to the outlet 230 through the second outlet channel 220. The heating component 140 is used to heat the water in the second outlet channel 220 according to the corresponding water intake mode to heat the water to the target temperature. It should be noted that the heating logic of the heating component 140 can be set according to the needs of the actual application scenario, and is not limited here.

[0050] It should be noted that one end of the first water outlet channel 210 and one end of the second water outlet channel 220 are both connected to the water outlet 230, and the connection section between the first water outlet channel 210 and the water outlet 230 shares the same water pipe as the connection section between the second water outlet channel 220 and the water outlet 230. In this embodiment, the ends of the first water outlet channel 210 and the second water outlet channel 220 share a portion of the water pipe, ensuring that users do not need to switch water outlets 230 when taking water, thus improving ease of use. This also facilitates subsequent intelligent water removal control logic, which can adaptively switch water outlet channels by monitoring the usage time interval and frequency of the water outlet channels, preventing the accumulation of stagnant water in the water pipes and affecting the water quality of the drinking water equipment.

[0051] In this embodiment, the control component 110 is connected to the first solenoid valve 120, the second solenoid valve 130 and the heating component 140 respectively, and controls the first solenoid valve 120, the second solenoid valve 130 and the heating component 140 respectively to achieve intelligent water circuit switching control by monitoring the usage of the first water outlet channel 210 and the second water outlet channel 220.

[0052] In one embodiment, such as Figure 3 As shown, a water circuit control method for a drinking water device is provided, which can be applied to... Figure 1 Taking the control component in the example, the following steps are included:

[0053] S301, Obtain historical water intake conditions, including the operating interval time of different water intake modes.

[0054] In this embodiment, the water intake mode includes a first water intake mode and a second water intake mode. In the first water intake mode, the water dispenser outputs room temperature water to the outlet through the first water outlet channel. In the second water intake mode, the water dispenser outputs hot water, i.e., high temperature water, to the outlet through the second water outlet channel.

[0055] In this embodiment, the operating interval of the water dispensing mode refers to the time difference between the previous operation time of the corresponding water dispensing mode and the current time. For example, if the current time is 12:00, the user operated the water dispenser to obtain hot water at 9:00, and then operated the water dispenser to obtain room temperature water at 10:00, and then did not operate the water dispenser until the current time. At the current time, the control component records the operating time interval of the first water dispensing mode as 2 hours and the operating time interval of the second water dispensing mode as 3 hours.

[0056] In practical applications, the control component can monitor the operation of the first water dispensing mode by monitoring the working state of the first switching valve, and the operation of the second water dispensing mode by monitoring the working state of the second switching valve. For example, if the first switching valve switches from a closed state to a conducting state and then back to a closed state, it is determined that the water dispenser has completed one water dispensing cycle according to the first water dispensing mode. If the second switching valve switches from a closed state to a conducting state and then back to a closed state, it is determined that the water dispenser has completed one water dispensing cycle according to the second water dispensing mode. In another embodiment, the control component can also monitor the operation of the water dispensing mode by monitoring the water temperature at the outlet. If the water temperature at the outlet is lower than a preset temperature value during a complete water dispensing cycle, it is determined that the water dispenser has completed one water dispensing cycle according to the first water dispensing mode. If the water temperature at the outlet is greater than or equal to a preset temperature value during a complete water dispensing cycle, it is determined that the water dispenser has completed one water dispensing cycle according to the second water dispensing mode. Here, a complete water dispensing cycle refers to the operation process of the water dispenser from the moment the user starts dispensing water to the moment the user stops dispensing water.

[0057] S302, if the operating interval of any water intake mode is greater than or equal to a preset time threshold, and the water intake mode is different from the current water intake mode, the first solenoid valve, the second solenoid valve and the heating component are controlled according to the stagnant water removal logic of the corresponding current water intake mode to complete the current water output.

[0058] In this embodiment, if the operating interval of any water intake mode is greater than or equal to a preset time threshold, it indicates that the residual water in the water channel corresponding to the water intake mode has been left to stand for too long, which may result in stagnant water. In this case, if the current water intake mode is the same as the water intake mode, there is no need to process it according to step S302. When the current water intake mode is running, the water channel corresponding to the water intake mode will be switched to the water conduction state, and the direct drinking water output by the purification system will push the residual water in the water pipe to the outlet, thereby realizing the output of the current water intake mode.

[0059] If the current water intake mode differs from the current water intake mode, the first solenoid valve, the second solenoid valve, and the heating element are controlled according to the stale water removal logic corresponding to the current water intake mode to complete the current water output. The stale water removal logic for the current water intake mode can be achieved by controlling the first and second solenoid valves to open simultaneously, then controlling the solenoid valve corresponding to the current water intake mode to open, while closing the other solenoid valve. This allows the filtered water to push out residual water in the idle pipeline, while ensuring the water output control of the drinking water equipment meets the user's normal water intake needs.

[0060] Based on the above steps, this embodiment provides a water circuit control method for drinking water equipment. Through idle mode identification and on-demand stale water removal control logic, it can effectively prevent stagnant water from forming in a single pipeline after prolonged stagnant flow, reducing odor and bacterial growth from the source and ensuring the health of users' drinking water. Furthermore, the entire process is automatically judged and executed by the control component, eliminating the need for manual triggering of flushing or pipeline switching by the user. This meets the maintenance-free requirements of home scenarios, greatly improving the convenience, safety, and water quality of the drinking water equipment.

[0061] It should be noted that, in one feasible embodiment, the water intake mode and the number of water outlet channels of the drinking water device can be adaptively increased according to the needs of the actual application scenario. For example, the drinking water device includes three water outlet channels, and the water intake mode also includes a third water intake mode, which is used to output cold water through the third water outlet channel. In one feasible embodiment, in the first water intake mode, the drinking water device can also output cold water through the first water outlet channel. It should be noted that the actual number of water outlet channels and the actual working method of the water intake mode can be adaptively changed according to the needs of the actual application scenario. After adding water outlet channels, the water circuit control method provided in this embodiment can still operate in the same principle. That is, when taking water according to the current water intake mode, the water outlet channel that has not been used for a long time is switched to the conducting state, and the drinking water output by the water purification system is used to flush the stagnant water inside the pipe, realizing intelligent stagnant water treatment in the pipe.

[0062] In one feasible embodiment, the preset time thresholds corresponding to the operating intervals of different water intake modes can be set to different time values. For example, to adapt to the habits of users in different regions, such as users in the south who use less hot water in summer, the preset time thresholds can be customized, setting the preset time threshold for the operating interval of the first water intake mode to 24 hours and the preset time threshold for the operating interval of the second water intake mode to 48 hours. It should be noted that the actual value of the preset time threshold can be determined according to the needs of the actual application scenario, and is not limited here.

[0063] In one embodiment, the water circuit control method for the drinking water device further includes:

[0064] If the operating interval of the first water intake mode is greater than or equal to the preset time threshold, and the current water intake mode is the second water intake mode, the first solenoid valve, the second solenoid valve, and the heating component are controlled according to the first stagnant water removal logic to complete the current water output.

[0065] If the operating interval of the second water intake mode is greater than or equal to the preset time threshold, and the current water intake mode is the first water intake mode, the first solenoid valve, the second solenoid valve, and the heating component are controlled according to the second water removal logic to complete the current water output.

[0066] In this embodiment, the drinking water device includes at least two stale water removal logics, and the triggering conditions for different stale water removal logics are different. Specifically, the triggering condition for the first stale water removal logic is that the operating interval of the first water dispensing mode is greater than or equal to a preset time threshold, and the current water dispensing mode is the second water dispensing mode. The triggering condition for the second stale water removal logic is that the operating interval of the second water dispensing mode is greater than or equal to a preset time threshold, and the current water dispensing mode is the first water dispensing mode.

[0067] In this embodiment, under the control of the first stale water removal logic, the water dispenser outputs hot water through the second water outlet channel. Under the control of the second stale water removal logic, the water dispenser outputs room temperature water or cold water through the first water outlet channel.

[0068] Based on the above steps, by setting different water removal logic, it can be ensured that when a water outlet channel with a safety risk is identified, that is, when a water outlet channel with residual water that has been sitting for a long time is identified, the water circuit control logic of the drinking water device can be intelligently switched to ensure that the residual water in the water outlet channel is effectively removed, avoid safety risks, reduce odor and bacterial growth from the source, and protect the user's drinking water health.

[0069] In one embodiment, such as Figure 4 As shown, the water circuit control method for drinking water equipment also includes:

[0070] S401, Obtain historical water intake conditions; historical water intake conditions also include the number of times different water intake modes were operated within a preset historical time period.

[0071] S402, if the number of times any water intake mode runs within a preset historical time period is less than or equal to a preset number threshold, and the water intake mode is different from the current water intake mode, the first solenoid valve, the second solenoid valve, and the heating component are controlled according to the stale water removal logic corresponding to the current water intake mode to complete the current water output.

[0072] In this embodiment, the number of times the water dispensing mode runs within a preset historical time period refers to the total number of times the corresponding water dispensing mode runs within a preset time period prior to the current time. For example, if the preset historical time period is 24 hours prior to the current time, and the user operates the water dispenser to dispense room temperature water 8 times and dispenses hot water once within those 24 hours, then the corresponding first water dispensing mode runs 8 times and the second water dispensing mode runs 1 time within the preset historical time period.

[0073] In this embodiment, the preset number of times threshold can be set to 0 or 1. It should be noted that the setting of the preset number of times threshold is related to whether the water dispenser follows steps S401-S402 to identify the application status of residual water in the channel in the actual application scenario, and whether the water dispenser starts following steps S401-S402 to identify the application status of residual water in the channel at a preset time or under preset conditions. For example, if the preset number of times threshold is set to 0, the same monitoring effect as steps S301-S302 can be achieved by configuring a preset historical time period in advance, i.e., identifying the usage time interval of the water outlet channel. If the preset number of times threshold is set to 1, steps S401-S402 to identify residual water in the channel can be started at regular intervals, and stagnant water can be removed from the water outlet channel that has not been used for a long time, thus effectively cleaning the water outlet channel of the water dispenser and improving the water quality of the water dispenser.

[0074] It should be noted that when the preset number of times threshold is greater than or equal to 1, the preset historical time interval will be adaptively extended as the preset number of times threshold increases.

[0075] In one embodiment, the water circuit control method for the drinking water device further includes:

[0076] If the number of times the first water intake mode runs within a preset historical time period is less than or equal to the preset number threshold, and the current water intake mode is the second water intake mode, the first solenoid valve, the second solenoid valve, and the heating component are controlled according to the first stagnant water removal logic to complete the current water output.

[0077] If the number of times the second water intake mode is run is less than or equal to the preset number threshold within a preset historical time period, and the current water intake mode is the first water intake mode, the first solenoid valve, the second solenoid valve, and the heating component are controlled according to the second stagnant water removal logic to complete the current water output.

[0078] In this embodiment, a logic trigger condition for removing stagnant water, different from the aforementioned steps S301-S302, is provided. This condition can be used alone or in combination to further improve the identification of idle mode of drinking water equipment and the effect of removing stagnant water on demand, thereby ensuring the health of users' drinking water.

[0079] In one embodiment, the specific steps for completing the current water output according to the first de-stagnant water logic control of the first solenoid valve, the second solenoid valve, and the heating assembly include:

[0080] The first and second solenoid valves are simultaneously turned on for a preset time, and the heating components are controlled to heat the water at a first power.

[0081] After a preset time, the first solenoid valve is closed, the second solenoid valve is opened, and the heating component is controlled to heat the water at the second power until the user stops taking water; wherein, the first power is greater than or equal to the second power.

[0082] In this embodiment, the first stale water removal logic includes two control stages. In the first control stage, the control component sends a command to simultaneously activate the first and second solenoid valves, thereby simultaneously activating the first water outlet channel (normal temperature water channel) and the second water outlet channel (hot water channel), and controls the heating component to heat at a first power. At this time, fresh filtered water flows through both channels simultaneously, pushing the stale water in the normal temperature water channel to the outlet for discharge, and the heating component heats at high power to ensure that the mixed outlet water temperature is close to the hot water standard set in the actual application scenario of the second water intake mode, preventing the water temperature from dropping due to mixing of the water in the two channels.

[0083] In the second control phase, the control component closes the first solenoid valve to stop the water supply from the ambient temperature water channel, keeping only the second solenoid valve open. Simultaneously, the heating component switches to second power heating, meaning it continues to heat the water at a lower power to maintain a stable hot water temperature until the user turns off the water dispenser.

[0084] In this embodiment, the duration of the first control phase and the second control phase is controlled by a preset time. In practical applications, the preset time can be set to 3-5 seconds (s). It should be noted that the preset time can be configured according to the needs of the actual application scenario. In one feasible embodiment, if the user's water demand is large (e.g., more than 5L), the preset time for the dual valves to be open can be extended from 3 seconds to 5 seconds, or the dual valves can be kept open until the water dispensing ends, to ensure that stagnant water in the idle pipeline is completely drained.

[0085] In one embodiment, the specific steps for completing the current water output according to the second water removal logic control of the first solenoid valve, the second solenoid valve, and the heating assembly include:

[0086] The first and second solenoid valves are simultaneously turned on for a preset time, and the heating component is turned off.

[0087] After a preset time, the first solenoid valve is turned on, the second solenoid valve is turned off, and the heating component stops until the user stops taking water.

[0088] In this embodiment, the second stale water removal logic also includes two control stages. In the first control stage, the control component sends a command to simultaneously activate the first and second solenoid valves and control the heating component to stop, thus avoiding heating room temperature water. At this time, the new filtered water flows through both channels simultaneously, pushing the stale water in the hot water channel to the outlet for discharge, ensuring that the room temperature water outlet temperature is not affected.

[0089] In the second control phase, the control component closes the second solenoid valve to stop the hot water supply to the hot water channel, while keeping the first solenoid valve open. The heating component continues to shut down until the user stops taking water.

[0090] In this embodiment, the setting of the preset time can be referred to the previous embodiment, and will not be repeated here.

[0091] Based on the above steps, the water circuit control method provided in this embodiment can perform short-term (e.g., 3 seconds) dual-valve common operation only when the triggering conditions are met, significantly reducing water waste compared to periodic forced flushing. Simultaneously, it avoids ineffective start-stop of the solenoid valve and heating components, extending the equipment's lifespan. Furthermore, the high-power start-up and low-power maintenance design in the first stale water removal logic effectively ensures that the initial outlet water temperature meets the standard in hot water mode, avoiding a sudden drop in water temperature caused by dual-valve common operation, thus balancing the stale water removal effect with the user experience.

[0092] In one embodiment, after controlling the first solenoid valve, the second solenoid valve, and the heating component according to the stale water removal logic corresponding to the current water intake mode to complete the current water output, the method further includes:

[0093] Update historical water intake conditions to reset the operating interval time of all water intake modes to zero, and / or increment the number of operations of all water intake modes by one.

[0094] In this embodiment, after the user stops taking water, the control component immediately updates the data. By resetting the running interval of all water taking modes to zero and / or incrementing the running count of all water taking modes by one, the frequent operation of the solenoid valve to execute the stale water removal logic of the water dispenser can be effectively avoided, thereby effectively protecting the components inside the water dispenser.

[0095] In summary, this embodiment provides a water circuit control method for drinking water equipment. By identifying historical operating conditions and intelligently triggering different stale water removal control logics, it effectively solves the stale water problem in dual-pipeline drinking water equipment, without requiring user intervention. Automatic cleaning of idle pipelines can be achieved through dual judgment of operating interval time and number of operations. Furthermore, the design of short-time dual-valve common operation and adaptive power adjustment balances stale water removal effect, user experience, and resource conservation, providing reliable support for the intelligent upgrade of household drinking water equipment.
