Description

Technical Field

[0001] This invention relates to the field of water purifier technology, and in particular to a water purifier and a mixing control method, system, and readable storage medium. Background Technology

[0002] Existing water purifiers typically include a room temperature water tank and a hot water tank to meet users' different drinking water temperature needs. The water purifier operates by heating the filtered water to a high temperature using a built-in heating element in the hot water tank, while the room temperature water tank stores filtered water at room temperature without heating. When a user draws water, a mixing valve mixes the room temperature water and hot water in a preset ratio to output warm water at a suitable temperature.

[0003] In pursuit of a compact design, the ambient temperature water tank and the hot water tank are typically located close together. This layout has drawbacks. When the device is in standby or not drawing water, the high-temperature water stored in the hot water tank continuously transfers heat to the nearby ambient temperature water tank via thermal radiation. This heat exchange causes the water temperature in the ambient temperature tank to passively rise. This increase in the base temperature of the ambient temperature water directly compresses the temperature difference range when it mixes with the hot water, significantly reducing the adjustable temperature range of the mixed water and impacting the user experience. The increased temperature in the ambient temperature water tank also creates conditions for microbial growth, increasing the risk to water quality safety. Simultaneously, the energy loss caused by the continuous outward radiation of heat from the hot water tank also increases the overall energy consumption of the device.

[0004] Furthermore, in the aforementioned water mixing mode, since the warm water itself has no independent heat source and relies entirely on the mixing of room temperature and hot water, the mixing ratio often varies significantly. For example, if the required warm water is 30 degrees Celsius, the room temperature water is 25 degrees Celsius, and the hot water is 90 degrees Celsius, the mixing ratio of room temperature and hot water would be approximately 12:1. In actual use, especially during continuous water extraction, the room temperature water is quickly drained due to its large volume, while a large amount of hot water remains in the hot water tank. This uneven utilization of the tank capacity not only limits the continuous water output of the equipment but also results in low overall water resource and heating energy efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the large difference in the mixing volume ratio of room temperature water and hot water leads to the easy draining of room temperature water, and to provide a water purifier and a mixing control method, system and readable storage medium.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] This invention provides a water purifier, which includes: a normal temperature water tank, a hot water tank, and a warm water tank;

[0008] The first water outlet pipe, the second water outlet pipe, and the third water outlet pipe are respectively connected to the outlet of the ambient temperature water tank, the outlet of the hot water tank, and the outlet of the warm water tank.

[0009] The first water outlet pump, the second water outlet pump, and the third water outlet pump are respectively installed on the first water outlet pipe, the second water outlet pipe, and the third water outlet pipe;

[0010] A connecting pipe, wherein the connecting pipe is used to connect the first water outlet pipe, the second water outlet pipe and the third water outlet pipe;

[0011] The first detection component, the second detection component, and the third detection component are respectively disposed in the room temperature water tank, the hot water tank, and the warm water tank, and are used to detect the parameters of the room temperature water tank, the hot water tank, and the warm water tank, respectively. The parameters include water temperature and water level.

[0012] The control unit is electrically connected to the first, second, and third water pumps. The control unit is used to control the start and stop of each water pump so that water from the corresponding water tank is mixed at the connecting pipeline and flows out.

[0013] In this design, connecting pipes link the outlet pipes of the ambient temperature water tank, hot water tank, and warm water tank. A control unit controls the first, second, and third outlet pumps based on the water temperature and level parameters in each tank, allowing for the selection of different tanks for mixing and adjusting the mixing ratio according to actual water demand. The addition of a warm water tank between the ambient temperature and hot water tanks increases both water capacity and the selection of a mixing tank, thus refining the mixing temperature range and reducing the temperature difference between the two tanks during mixing. This effectively reduces the output volume and mixing volume ratio of the two tanks, preventing rapid emptying of any single tank. This structure ensures stable water temperature from the purifier, improving the user experience and guaranteeing a continuous and reliable water supply.

[0014] Preferably, the warm water tank is located between the ambient temperature water tank and the hot water tank.

[0015] In this solution, by placing the warm water tank between the ambient temperature water tank and the hot water tank, the heat radiation from the hot water tank can be transferred to the warm water tank. Therefore, the water temperature in the warm water tank can be maintained between the ambient temperature and hot water tank temperatures without the need for an additional heating device. Consequently, during standby, the warm water tank can recover the heat radiated by the hot water tank, thus preventing energy waste caused by heat loss from the hot water tank.

[0016] Preferably, the water purifier further includes a first heat insulation component, which is disposed between the ambient temperature water tank and the warm water tank;

[0017] And / or, the water purifier further includes a second heat insulation component, which is disposed between the warm water tank and the hot water tank. In this solution, by setting a first heat insulation component between the ambient temperature water tank and the warm water tank, heat radiation from the hot water tank can be blocked, reducing the possibility of heat radiation transfer to the ambient temperature water tank, thereby ensuring that the ambient temperature water tank maintains a lower temperature and preventing a reduction in the mixing temperature range. Furthermore, because a second heat insulation component is set between the warm water tank and the hot water tank, the possibility of heat radiation transfer to the warm water tank and then to the ambient temperature water tank is reduced, thereby ensuring that the ambient temperature water tank maintains a lower temperature and preventing a reduction in the mixing temperature range.

[0018] Preferably, the ambient temperature water tank and / or the warm water tank are equipped with a germicidal lamp, which is used for ultraviolet sterilization.

[0019] In this solution, germicidal lamps are installed in both the ambient temperature water tank and the warm water tank.

[0020] The present invention also provides a water mixing control method for a water purifier, the control method being used to control the water purifier as described in any of the above technical solutions, the water mixing control method comprising:

[0021] Set the desired outlet water temperature T0;

[0022] The water temperatures of the ambient temperature water tank, the hot water tank, and the warm water tank are respectively detected by the first detection component, the second detection component, and the third detection component as T1, T2, and T3;

[0023] Based on the relationship between T0 and T1, T2, and T3, the target water discharge mode is determined, and the target water discharge mode involves one or more water tanks;

[0024] When executing the target water output mode, the water levels of the ambient temperature water tank, the hot water tank, and the warm water tank are detected by the first detection component, the second detection component, and the third detection component, respectively, and it is determined whether the water levels of each tank meet the water output requirements.

[0025] If the water levels in all the water tanks meet the requirements, the corresponding water pump will be turned on according to the target water outlet mode, so that the water from different water tanks will be mixed in the connecting pipeline until the water outlet temperature reaches T0.

[0026] If the water level in the tank does not meet the requirements, adjust the water outlet mode or stop the water outlet.

[0027] In this solution, the mixing control method first determines the outlet water tank based on the relationship between the required outlet water temperature T0 and the water temperature of each tank, thus establishing the target outlet water mode. Then, based on whether the water level in the tanks involved in the target outlet water mode meets the outlet water requirements, it adjusts the outlet water mode or stops the outlet water flow. By adding a warm water tank between the ambient temperature tank and the hot water tank, the water capacity is increased, and the selection of the mixing water tank is expanded. This refines the temperature range for mixing, reduces the temperature difference between the two tanks during mixing, effectively lowers the outlet water volume and mixing volume ratio of the two tanks, and prevents the rapid emptying of any single tank. This structure ensures a stable outlet water temperature for the water purifier, which not only improves the user's water experience but also guarantees a continuous and reliable water supply.

[0028] Preferably, the step of determining the target water discharge mode based on the relationship between T0 and T1, T2, and T3, wherein the target water discharge mode involves one or more water tanks, specifically includes:

[0029] Determine whether T0 is between T1 and T3. If so, the target water output mode is a mixture of room temperature water and warm water, and then turn on the first water output pump and the third water output pump.

[0030] If not, the target water output mode is a mixture of warm and hot water, and the second and third water output pumps are turned on.

[0031] In this solution, the required outlet water temperature T0 is determined based on the relationship between the measured water temperatures T1, T2, and T3 of each water tank. The control unit can avoid selecting a mixing tank with an excessively high mixing ratio due to excessive temperature differences. When T0 is between room temperature and warm water, room temperature and warm water are mixed first to avoid directly using hot water with a large temperature difference, thus significantly reducing the consumption rate of room temperature water. When T0 is between warm water and hot water, the system switches to a warm water and hot water mixing mode, again avoiding directly using room temperature water with a large temperature difference, thus significantly reducing the consumption rate of room temperature water. This method matches the water tank combination with the smallest temperature difference for water dispensing, thereby reducing the possibility of excessive extraction and rapid emptying of room temperature water due to excessive temperature differences. It also effectively improves the efficiency and accuracy of outlet water temperature regulation, ensuring that the water purifier can achieve a stable water supply under various water demand conditions.

[0032] Preferably, the target water output mode also includes a mixed mode of room temperature water and hot water;

[0033] The steps for adjusting the water outlet mode or stopping the water outlet if the water level in the tank does not meet the requirements specifically include:

[0034] In the mixed mode of room temperature water and warm water, if the water level in the room temperature water tank does not meet the requirements, the water output will stop; if the water level in the warm water tank does not meet the requirements, the target water output mode will be switched to the mixed mode of room temperature water and hot water, and the first water output pump and the second water output pump will be turned on.

[0035] In the mixed hot and warm water mode, if the water level in the hot water tank does not meet the demand, the water output will stop; if the water level in the warm water tank does not meet the demand, the target water output mode will be switched to the mixed hot and warm water mode, and the first water pump and the second water pump will be turned on.

[0036] In this solution, by adding a target water output mode that mixes room temperature water and hot water, the system can switch to a mixed water mode that combines room temperature water and hot water when the water volume in the warm water tank is insufficient, thereby further ensuring the stability of the water supply.

[0037] Preferably, the step of detecting the water levels of the ambient temperature water tank, the hot water tank, and the warm water tank using the first detection component, the second detection component, and the third detection component respectively, and determining whether the water levels of each tank meet the water dispensing requirements when executing the target water dispensing mode, specifically includes:

[0038] Set the abnormal water level H0 for each water tank;

[0039] The water levels of the ambient temperature water tank, the hot water tank, and the warm water tank are respectively detected by the first detection component, the second detection component, and the third detection component as H1, H2, and H3;

[0040] Determine whether H1, H2, and H3 are greater than H0. If they are, the water output requirement is met; otherwise, the water output requirement is not met.

[0041] In this solution, by setting an abnormal water level H0 and detecting the actual water levels H1, H2, and H3 in each tank, the control unit can pre-determine whether the water volume in the tanks is sufficient under the target water dispensing mode before executing the water dispensing operation. Water dispensing proceeds normally when all relevant tank levels are above the abnormal level; however, if any tank level is below H0, it is determined that the water dispensing demand is not met, and subsequent operations are promptly taken, such as switching modes or stopping water dispensing. This method further reduces the possibility of a tank being rapidly emptied during the mixing process due to a low water level, effectively protecting the water pump from damage caused by dry running, and preventing water dispensing interruptions due to mid-stream water cutoffs, ensuring the stability and reliability of the water purifier during long-term use.

[0042] The present invention also provides a water mixing control system for a water purifier, used to execute the water mixing control method of any of the above-mentioned water purifiers, wherein the water mixing control system of the water purifier includes:

[0043] The setting module is used to set the desired outlet water temperature;

[0044] The acquisition module is used to acquire parameters of the ambient temperature water tank, the hot water tank, and the warm water tank, the parameters including water temperature and water level;

[0045] The determining module is used to determine the target water outlet mode based on the current water temperature and water level of the ambient temperature water tank, the hot water tank, and the warm water tank. The target water outlet mode includes a mixed mode of ambient temperature water and warm water, a mixed mode of warm water and hot water, and a mixed mode of ambient temperature water and hot water.

[0046] The control module is used to control the water purifier to turn on the corresponding water pump according to the determined target water output mode, so that water from different water tanks is mixed in the connecting pipeline to control the water temperature.

[0047] The present invention also provides a readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the water mixing control method of any of the above water purifiers.

[0048] The positive and progressive effects of this invention are as follows:

[0049] This invention provides a water purifier and a mixing control method, system, and readable storage medium. It connects the outlet pipes of a normal temperature water tank, a hot water tank, and a warm water tank via a connecting pipeline. A control unit controls a first, second, and third outlet pump based on the water temperature and level parameters in each tank, thereby selecting the appropriate tank for mixing and adjusting the mixing ratio according to actual water demand. By adding a warm water tank between the normal temperature and hot water tanks, the water capacity is increased, and the selection of a mixing tank is expanded, thus refining the mixing temperature range and reducing the temperature difference between the two tanks during mixing. This effectively reduces the water output and mixing volume ratio of the two tanks, preventing rapid emptying of any single tank. This structure ensures stable water temperature from the purifier, improving the user experience and guaranteeing a continuous and reliable water supply. Attached Figure Description

[0090] Control Module 17 Detailed Implementation

[0091] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0092] Example 1.

[0093] like Figures 1 to 2 As shown, this embodiment provides a water purifier 1000, which includes multiple water tanks, multiple water outlet pipes, multiple water pumps, multiple detection components, a control unit, and connecting pipes 4. In this embodiment, the multiple water tanks are three: a normal temperature water tank 1, a hot water tank 2, and a warm water tank 3. The hot water tank 2 is equipped with a heating element.

[0094] like Figure 2 As shown, in this embodiment, there are three water outlet pipes: the first water outlet pipe 301, the second water outlet pipe, and the third water outlet pipe. The first water outlet pipe 301, the second water outlet pipe, and the third water outlet pipe are respectively connected to the outlet of the ambient temperature water tank 1, the outlet of the hot water tank 2, and the outlet of the warm water tank 3.

[0095] like Figure 2 As shown, in this embodiment, there are three water pumps: a first water pump 302, a second water pump, and a third water pump. These three pumps are respectively installed on the first water outlet pipe 301, the second water outlet pipe, and the third water outlet pipe, and are used to control the opening and closing of these pipes. A connecting pipe 4 connects the first water outlet pipe 301, the second water outlet pipe, and the third water outlet pipe, and is used to mix the water from each pipe before discharging it. A control unit is electrically connected to the first water pump 302, the second water pump, and the third water pump. The control unit controls the start and stop of each pump, selectively discharging water from the corresponding water tank, mixing it at the connecting pipe 4, and then allowing it to flow out.

[0096] In this embodiment, there are three detection components (all located in each water tank, not shown in the figure): a first detection component, a second detection component, and a third detection component. The first detection component, the second detection component, and the third detection component are respectively located in the ambient temperature water tank 1, the hot water tank 2, and the warm water tank 3, and are used to detect the parameters of the ambient temperature water tank 1, the hot water tank 2, and the warm water tank 3, including but not limited to water temperature and water level.

[0097] Thus, by setting up connecting pipe 4 to connect the corresponding water outlet pipes of the ambient temperature water tank 1, hot water tank 2, and warm water tank 3, and using the control unit to control the first, second, and third water outlet pumps based on the water temperature and level parameters in each tank, different water tanks can be selected for mixing and the mixing ratio can be adjusted according to actual water demand. Because a warm water tank 3 is added between the ambient temperature water tank 1 and the hot water tank 2, the water capacity is increased while the selection of a mixing tank is expanded, thereby refining the temperature range for mixing and reducing the temperature difference between the two tanks during mixing. This effectively reduces the water output and mixing volume ratio of the two tanks during mixing, thus preventing the rapid emptying of any single tank. This structure ensures the stability of the water outlet temperature of the water purifier 1000, which not only improves the user's water experience but also guarantees a continuous and reliable water supply.

[0098] In this embodiment, the first detection component includes a first water temperature detection device for detecting the water temperature of the ambient temperature water tank 1 and a first water level detection device for detecting the water level in the ambient temperature water tank 1. The second detection component includes a second water temperature detection device for detecting the water temperature of the hot water tank 2 and a second water level detection device for detecting the water level in the hot water tank 2. The third detection component includes a third water temperature detection device for detecting the water temperature of the warm water tank 3 and a third water level detection device for detecting the water level in the warm water tank 3. Thus, by respectively installing water temperature detection devices and water level detection devices in the ambient temperature water tank 1, the hot water tank 2, and the warm water tank 3, the control unit can accurately acquire water temperature and water level data in real time, facilitating the accurate selection of the appropriate water tank for mixing and ensuring the accuracy of the outlet water temperature.

[0099] In other embodiments, if other detection parameters besides water temperature and water level are added, then detection devices for those other parameters can be added. The detection components in this embodiment include, but are not limited to, a water temperature detection device and a water level detection device.

[0100] like Figure 1As shown, in this embodiment, a room temperature water tank 1, a warm water tank 3, and a hot water tank 2 are arranged sequentially and alternately, with the warm water tank 3 positioned between the room temperature water tank 1 and the hot water tank 2. By placing the warm water tank 3 between the room temperature water tank 1 and the hot water tank 2, the heat radiation from the hot water tank 2 can be transferred to the warm water tank 3. Therefore, the water temperature in the warm water tank 3 can be maintained between the temperatures of the room temperature water tank 1 and the hot water tank 2 without the need for an additional heating device. Consequently, during standby, the warm water tank 3 can recover the heat radiated by the hot water tank 2, thus preventing heat loss from the hot water tank 2 and energy waste.

[0101] like Figure 1 As shown, the water purifier 1000 also includes a first heat insulation component 501 and a second heat insulation component 502. The first heat insulation component 501 is disposed between the ambient temperature water tank 1 and the warm water tank 3, and the second heat insulation component is disposed between the warm water tank 3 and the hot water tank 2. It is worth noting that simply placing the first heat insulation component 501 between the ambient temperature water tank 1 and the warm water tank 3 is sufficient to prevent heat radiation from being conducted to the ambient temperature water tank 1, thus preventing a temperature rise. In this way, by placing the first heat insulation component 501 between the ambient temperature water tank 1 and the warm water tank 3, heat radiation from the hot water tank 2 can be blocked, reducing the possibility of heat radiation being transferred to the ambient temperature water tank 1. This ensures that the ambient temperature water tank 1 maintains a lower temperature, preventing a narrowing of the mixing water temperature range. In this embodiment, placing the second heat insulation component 502 between the hot water tank 2 and the warm water tank 3 would further prevent a temperature rise in the ambient temperature water tank 1, but it would also reduce the ability of the warm water tank 3 to absorb heat radiation. Therefore, the second heat insulation component 502 between the hot water tank 2 and the warm water tank 3 is not essential; this embodiment is merely illustrative.

[0102] In this embodiment, the first heat insulation element 501 and the second heat insulation element 502 are existing vacuum heat insulation layers, which will not be elaborated in this embodiment.

[0103] Furthermore, sterilization lamps are installed in the ambient temperature water tank 1 and the warm water tank 3. The sterilization lamps are ultraviolet sterilization lamps with UV lamp tubes for ultraviolet sterilization.

[0104] Furthermore, the water purifier 1000 also includes a filter 6, which is connected to each water tank through an inlet pipe. The water entering each water tank is pure water filtered by the filter 6.

[0105] Example 2.

[0106] like Figure 3 and Figure 4 As shown, this embodiment provides a water mixing control method for a water purifier. The control method is used to control the water purifier 1000 of Embodiment 1. The water mixing control method includes:

[0107] Step S1: The user sets the desired outlet water temperature T0;

[0108] Step S2: After receiving the instruction, the control unit uses the first water temperature detection device, the second water temperature detection device and the third water temperature detection device to detect the water temperatures of the ambient temperature water tank 1, the hot water tank 2 and the warm water tank 3 respectively as T1, T2 and T3.

[0109] Step S3: Compare T0 with T1, T2, and T3. Based on the relationship between T0 and T1, T2, and T3, determine the target water discharge mode. The target water discharge mode involves one or more water tanks.

[0110] Step S4: When executing the target water output mode, the water levels of the ambient temperature water tank 1, hot water tank 2 and warm water tank 3 are detected by the first water level detection device, the second water level detection device and the third water level detection device respectively, and it is determined whether the water levels of each water tank meet the water output requirements.

[0111] Step S5: If the water levels in all involved water tanks meet the requirements, the corresponding water pump is turned on according to the target water outlet mode, so that the water from different water tanks is mixed in the connecting pipe 4 until the water outlet temperature reaches T0; if the water tank levels do not meet the requirements, the water outlet mode is adjusted or the water outlet is stopped.

[0112] T0 should be between the lowest water temperature T1 and the highest water temperature T2. If T0 is not between T1 and T2, then the water temperature cannot be obtained by mixing water. Under normal circumstances, the temperature of T1 is room temperature, about 15 to 25 degrees Celsius, and T2 is hot water heated to boiling, about 90 to 100 degrees Celsius. The temperature of the water required by the user is usually between T1 and T2.

[0113] Thus, the required outlet water temperature T0 is determined based on the relationship between the measured water temperatures T1, T2, and T3 of each water tank. The control unit can avoid selecting a mixing tank with an excessively high mixing ratio due to excessive temperature differences. When T0 is between room temperature and warm water, room temperature and warm water are mixed first to avoid directly using hot water with a large temperature difference, thereby significantly reducing the consumption rate of room temperature water. When T0 is between warm water and hot water, the system switches to a warm water and hot water mixing mode, again avoiding directly using room temperature water with a large temperature difference, thereby significantly reducing the consumption rate of room temperature water. This method matches the water tank combination with the smallest temperature difference for water dispensing, thereby reducing the possibility of excessive extraction and rapid emptying of room temperature water due to excessive temperature differences. It also effectively improves the efficiency and accuracy of outlet water temperature adjustment, ensuring that the water purifier 1000 can achieve a stable water supply under various water demand conditions.

[0114] In this embodiment, based on the three water tanks 1 (room temperature water tank), 3 (warm water tank), and 2 (hot water tank), the target water output mode includes three modes when they are combined in pairs: room temperature water and warm water, warm water and hot water, and room temperature water and hot water mixed mode.

[0115] In other embodiments, there can be more than three water tanks, which further divides the temperature range between room temperature water and hot water, and the water output mode based on the number of water tanks is not limited to the above three types.

[0116] Step S3 specifically includes:

[0117] Step S31: Determine whether T0 is between T1 and T3. If so, determine that the target water output mode is a mixture of room temperature water and warm water, and turn on the first and third water output pumps. If not, determine that the target water output mode is a mixture of warm water and hot water, and turn on the second and third water output pumps.

[0118] The system determines the mixing tank selection based on the relationship between the required outlet water temperature T0 and the measured water temperatures T1, T2, and T3 in each tank. This avoids selecting a tank with an excessively high mixing ratio due to large temperature differences. When T0 is between room temperature and warm water, it prioritizes mixing room temperature and warm water to avoid directly using hot water with a large temperature difference, thus significantly reducing the consumption rate of room temperature water. When T0 is between warm water and hot water, it switches to a warm water and hot water mixing mode, again avoiding directly using room temperature water with a large temperature difference, thus significantly reducing the consumption rate of room temperature water. When T0 equals one of T1, T2, or T3, no mixing is needed, and the tank can dispense water directly. In this case, the target mixing mode only involves one tank. This method uses water tank combinations with the smallest temperature difference to dispense water, thereby reducing the possibility of excessive extraction of room temperature water due to large temperature differences, which would lead to rapid emptying. It also effectively improves the efficiency and accuracy of water temperature regulation, ensuring that the 1000 water purifier can provide stable water supply under various water demand conditions.

[0119] In step S5, the step of "adjusting the water outlet mode or stopping the water outlet if the water level in the water tank does not meet the requirements" specifically includes two situations: First, in the mixed mode of room temperature water and warm water, if the water level in room temperature water tank 1 does not meet the requirements, the water outlet is stopped; Second, if the water level in warm water tank 3 does not meet the requirements, the target water outlet mode is switched to the mixed mode of room temperature water and hot water, and the first water outlet pump and the second water outlet pump are turned on.

[0120] In the hot and warm water mixing mode, if the water level in hot water tank 2 is insufficient, water flow stops; if the water level in warm water tank 3 is insufficient, the target water flow mode is switched to a mixed mode of room temperature and hot water, and the first and second water pumps are activated. Thus, by adding a target water flow mode of mixed room temperature and hot water, the system can switch to a mixed mode of room temperature and hot water when the water level in warm water tank 3 is insufficient, further ensuring the stability of the water supply.

[0121] Specifically, in step S4, the step of "when executing the target water output mode, detecting the water levels of the ambient temperature water tank 1, hot water tank 2, and warm water tank 3 respectively through the first water level detection device, the second water level detection device, and the third water level detection device, and determining whether the water levels of each tank meet the water output requirements" specifically includes:

[0122] Step S41: Set the abnormal water level H0 for each water tank;

[0123] Step S42: The water levels of the ambient temperature water tank 1, hot water tank 2, and warm water tank 3 are respectively detected by the first detection component, the second detection component, and the third detection component as H1, H2, and H3;

[0124] Step S43: Determine whether H1, H2, and H3 are greater than H0. If they are, the water output requirement is met; otherwise, the water output requirement is not met.

[0125] Thus, by setting an abnormal water level H0 and detecting the actual water levels H1, H2, and H3 in each tank, the control unit can pre-determine whether the water volume in the tanks is sufficient for the target water dispensing mode before executing the dispensing operation. Dispensing proceeds normally when all relevant tanks are above the abnormal water level; however, if any tank's water level is below H0, it is determined that the dispensing demand is not met, and subsequent operations are promptly taken, such as switching modes or stopping dispensing. This method further reduces the possibility of a tank being rapidly emptied during the mixing process due to a low water level, effectively protecting the water pump from dry running damage and preventing water dispensing interruptions due to mid-way water supply interruptions, ensuring the stability and reliability of the water purifier 1000 during long-term use.

[0126] Furthermore, the mixing control method can also include a step S6 after the water is discharged in step S5. Step S6 includes:

[0127] Step S61: When not mixing water, set the warning water level of the normal temperature water tank 1. The warning water level is higher than the abnormal water level.

[0128] Step S62: The first water level detection device, the second water level detection device and the third water level detection device detect the water level of each water tank in real time. When the water level of each water tank is lower than the warning water level but higher than the abnormal water level, water is added and room temperature water is introduced. When the water level of the warm water tank 3 is lower than the warning water level but higher than the abnormal water level, the inlet valve is opened to introduce room temperature water into the warm water tank 3.

[0129] Furthermore, the mixing control method can also include a step S7 after the water is discharged in step S5. Step S7 includes:

[0130] Step S71: When not mixing water, set the standard water temperature of hot water tank 2;

[0131] Step S72: When the second water temperature detection device detects that the water temperature in the hot water tank 2 is lower than the standard water temperature, it stops the water flow and starts the heating element to heat the water.

[0132] Furthermore, the mixing control method can also include a step S8 after the water is discharged in step S5. Step S8 includes:

[0133] Step S81: When not mixing water, set the warning water temperature of the normal temperature water tank 1;

[0134] Step S82: When the first water temperature detection device detects that the water temperature of the ambient temperature water tank 1 is higher than the warning water temperature, it stops discharging water and reports an error.

[0135] The order of steps S6, S7, and S8 is not limited.
