The water replenishment control method includes: acquiring the liquid level in the insulation tank and comparing it with a preset liquid level to determine the liquid level range; acquiring the state of the water inlet of the water supply equipment to determine if it is in water intake mode; when the water inlet of the water supply equipment is in water intake mode and the liquid level in the insulation tank is lower than the low liquid level, controlling the water replenishment device to start water replenishment until the liquid level in the insulation tank reaches the middle liquid level, and then stopping water replenishment. By acquiring the state of the water inlet of the water supply equipment, water replenishment can be initiated only when the liquid level in the insulation tank is lower than the low liquid level during water intake mode, and water replenishment can be stopped once the liquid level reaches the middle liquid level, thereby minimizing the drop in water temperature in the insulation tank caused by water replenishment and ensuring a stable water flow rate; since the liquid level is only replenished to the middle liquid level, compared with the method of replenishing the tank completely each time, the heating and insulation energy consumption can be effectively reduced.

Description

Technical Field

[0001] This invention relates to the field of water supply equipment technology, specifically to a water supply equipment with an insulated tank, a water replenishment control method, a device, a computer device, and a storage medium. Background Technology

[0002] With the increasing popularity of heated water purifiers, hot water insulated tanks are also being added to various types of water purifiers. Water supply equipment with built-in insulated tanks has become a market trend due to its convenient hot water supply and stable temperature rise.

[0003] Currently, the mainstream methods for replenishing water in insulated tanks are twofold: first, refilling the tank after dispensing and then preheating it; second, refilling and preheating only after the liquid level reaches a set value. While the former ensures sufficient water volume and temperature, it consumes a significant amount of energy over extended periods. The latter, where water replenishment is triggered during dispensing, causes a drop in water temperature inside the tank, resulting in a slower flow rate. Therefore, these water replenishment methods for insulated tanks either have high energy consumption or slow flow rates, negatively impacting the user experience. Summary of the Invention

[0004] In view of this, the present invention provides a water replenishment control method, device, computer equipment and storage medium for water supply equipment, so as to solve the problems of high energy consumption or slow water flow rate in the related technology of water replenishment by insulated tanks, which affect the user experience.

[0005] In a first aspect, the present invention provides a water replenishment control method for a water supply device, the water supply device including a heat preservation tank, the water replenishment control method comprising:

[0006] Obtain the status of the water intake of the water supply equipment to determine whether it is in water intake mode;

[0007] The liquid level inside the insulation tank is obtained and compared with the preset liquid level, which includes low, medium and high liquid levels; it is then determined whether the liquid level inside the insulation tank is lower than the low liquid level.

[0008] When the water intake of the water supply equipment is in the water intake state and the liquid level in the insulation tank is lower than the low liquid level, the water replenishment device is started to replenish water until the liquid level in the insulation tank reaches the medium liquid level and then the water replenishment stops.

[0009] Beneficial effects: The preset low liquid level is the water shortage limit level or close to the water shortage limit level; by acquiring the status at the water intake of the water supply equipment, water can be added only when the liquid level in the insulation tank is lower than the low liquid level during water intake, and water intake is stopped once the liquid level reaches the middle liquid level, thereby minimizing the drop in water temperature in the insulation tank caused by water intake, ensuring a stable water intake flow rate, and avoiding water temperature fluctuations; since the liquid level is only added to the middle liquid level, it can effectively reduce heating and insulation energy consumption compared to the method of filling the tank every time.

[0010] In one optional implementation, the control of the water replenishment device to initiate water replenishment includes:

[0011] Obtain the current first water intake rate;

[0012] The first water replenishment rate is determined based on the first water intake rate;

[0013] The water replenishment device is controlled to replenish water at a predetermined first water replenishment rate.

[0014] Beneficial effects: By obtaining the current water intake rate, the water replenishment rate is determined, and the water replenishment device is controlled to replenish water at the determined rate, thereby controlling the water replenishment rate more precisely, so that the water replenishment rate is greater than the water intake rate, and the water level in the insulated tank can continue to rise during the water intake process.

[0015] In one optional implementation, obtaining the current first water intake rate includes:

[0016] The first time it takes for the liquid level to drop from the middle level to the low level is obtained, and the first water intake rate is calculated.

[0017] Alternatively, obtain the monitoring value of the flow meter at the water intake;

[0018] Alternatively, obtain the flow rate curve of the water intake pump to determine the first water intake rate.

[0019] Beneficial effects: Since the area of ​​the insulated tank is fixed, the liquid level difference between the middle and low liquid levels is also fixed. The volume change can be calculated, and the time it takes for the liquid level to drop from the middle to the low liquid level can be obtained. The ratio of volume change to time is the volumetric flow rate, i.e., the water intake rate. The water intake rate is calculated using the above method, and the feedback is relatively fast. The water intake rate is more accurate by directly monitoring the flow meter at the water intake port. The flow curve of the water intake pump can be obtained. This flow curve is a static characteristic curve provided by the water pump manufacturer. The flow rate can be estimated based on this flow curve to determine the first water intake rate without the need for sensors.

[0020] In one alternative implementation, the first water replenishment rate satisfies:

[0021] First water replenishment rate = First water intake rate * K;

[0022] Where K is the adjustment coefficient, and K∈[1.2, 1.5].

[0023] Beneficial effects: The water replenishment rate and the water intake rate satisfy the above relationship, ensuring that the water replenishment rate can compensate for the water intake rate, and that the liquid level in the insulation tank can rise synchronously while water is being taken out; if the adjustment coefficient is too large, it will cause the water replenishment to be too large, causing the water temperature in the insulation tank to drop too quickly, while if the adjustment coefficient is too close to 1, the water replenishment speed will be too slow, which will prolong the user's waiting time.

[0024] In one optional implementation, after the liquid level in the insulation tank reaches the middle level, the method further includes:

[0025] Continuously monitor the status of the water intake of the water supply equipment to determine whether it is in water intake mode;

[0026] When the water inlet is in the water intake state, the liquid level in the insulation tank is obtained to determine whether the liquid level has dropped to a low level.

[0027] When the liquid level in the insulation tank drops to the low level, the water replenishment device is restarted until the liquid level in the insulation tank rises to the medium level, at which point the water replenishment stops.

[0028] Beneficial effects: After the liquid level in the insulated tank reaches the middle level, the system continuously monitors the water intake status and the liquid level in the insulated tank. If the liquid level is lower than the low level, water is added; if the liquid level is reached, water addition stops. This allows for small, frequent water replenishment, keeping the water temperature in the insulated tank within a relatively small range. When hot water is taken out, the water heats up quickly, ensuring a stable water intake speed for the user and providing a good user experience.

[0029] In one optional implementation, the water replenishment control method further includes:

[0030] If the water inlet is in the water intake state and the liquid level in the insulation tank has not dropped to the low level, no water needs to be added until the water inlet is in the non-water intake state.

[0031] Beneficial effect: If the liquid level in the insulated tank does not drop to a low level while the water is being drawn, it indicates that there is no water shortage that would affect water drawing. At this time, no water should be added to ensure that the water temperature in the insulated tank does not drop due to water addition and the water drawing speed will not be affected.

[0032] In one optional implementation, the water replenishment control method further includes:

[0033] When the water intake of the water supply equipment is not in a water intake state and the liquid level in the insulation tank is lower than the middle liquid level, the water replenishment device will start to replenish water until the liquid level in the insulation tank reaches the middle liquid level and then the water replenishment will stop.

[0034] Beneficial effects: The medium liquid level is the liquid level between the low and high liquid levels. When the liquid level is higher than the medium liquid level, it indicates that there is enough liquid in the heat preservation tank, and it can stably supply water for a period of time during the next water intake without the need to add water. When the liquid level is lower than the medium liquid level, water needs to be added to meet the next water intake needs. Adding water only to the medium liquid level can reduce heat preservation energy consumption and save energy.

[0035] In one optional implementation, the control of the water replenishment device to initiate water replenishment includes:

[0036] Obtain the second water intake rate from the previous water intake process;

[0037] The second water replenishment rate is determined based on the second water intake rate;

[0038] The water replenishment device is controlled to replenish water at a determined second water replenishment rate.

[0039] Beneficial effect: If the liquid level is lower than the middle level when not taking water, it means that some water was taken away in the previous water taking process. Therefore, the water replenishment rate should be determined according to the water taking rate of the previous water taking process, and then the water replenishment device should be controlled to replenish water at the determined water replenishment rate. Only in this way can the water replenishment time be set more reasonably.

[0040] In one optional implementation, obtaining the second water intake rate from the previous water intake process includes:

[0041] The second time it takes for the liquid level to drop from the high level to the middle level is obtained, and the second water intake rate is calculated.

[0042] Alternatively, obtain the monitoring value of the flow meter at the water intake;

[0043] Alternatively, obtain the flow rate curve of the water intake pump to determine the second water intake rate.

[0044] Beneficial effects: Since the water level is either high after being filled or has been replenished to the middle level, if the water level is lower than the middle level when not in use, it indicates that the water level dropped from high to below the middle level during the previous water intake process. Therefore, the volumetric flow rate, i.e., the water intake rate, can be calculated by combining the time it takes for the water level to drop from high to middle level with the volume change, which is a relatively quick process. The water intake rate is more accurate when monitored directly by the flow meter at the water intake port. The flow curve of the water intake pump can be obtained, and the flow rate can be estimated based on the flow curve to determine the first water intake rate without the need for sensors.

[0045] In one alternative implementation, the second water replenishment rate satisfies:

[0046] Second water replenishment rate = Second water intake rate * K;

[0047] Where K is the adjustment coefficient, and K∈[1.2, 1.5].

[0048] Beneficial effects: The water replenishment rate and the water extraction rate satisfy the above relationship, ensuring that the water replenishment rate can compensate for the water extraction rate, and that the liquid level in the insulation tank can rise synchronously while water is being extracted; if the adjustment coefficient is too large, it will cause the water replenishment to be too large, causing the water temperature in the insulation tank to drop too quickly, while if the adjustment coefficient is too close to 1, the water replenishment speed will be too slow, which will prolong the user's waiting time and cause a bad experience.

[0049] In one optional embodiment, the water replenishment control method further includes:

[0050] Obtain the duration of the non-water intake state and determine whether it exceeds the preset duration;

[0051] If the duration of the non-water intake state exceeds the preset duration, the water replenishment device will replenish water at the preset maximum water replenishment rate until the liquid level in the insulation tank reaches the high level and then the water replenishment will stop.

[0052] Beneficial effect: The duration of non-water intake is longer than the preset duration, indicating that it is in the water intake idle period. At this time, the water temperature in the cold water insulation tank drops, which will not cause a decrease in water output or slow water output. Therefore, the water replenishment device is directly controlled to replenish water at the preset maximum water replenishment rate until the liquid level in the insulation tank reaches the high level and then the water replenishment stops. The insulation tank is filled with water, so as to reduce the need for water replenishment during the water intake process.

[0053] In one optional implementation, after the liquid level in the insulation tank reaches the high level, the method further includes:

[0054] Get the water temperature inside the insulated tank and determine whether it has dropped to the first preset water temperature;

[0055] When the water temperature in the insulation tank has dropped to the first preset water temperature, the heating device is activated to heat the water until the water temperature in the insulation tank rises to the second preset water temperature and then heating stops.

[0056] Beneficial effects: After the insulated tank is filled with water, the water temperature inside the tank is measured to determine whether heating is needed. When the water temperature is lower than the first preset water temperature, it indicates that the water temperature inside the insulated tank is low. If it is not preheated, the heating time during water dispensing will be prolonged, and the water temperature will easily fluctuate. Therefore, heating is carried out when the water temperature is lower than the first preset water temperature until the water temperature inside the insulated tank rises to a more suitable second preset water temperature. If it is higher than the second preset water temperature, it will increase energy consumption too much.

[0057] In one optional implementation, the water replenishment control method further includes:

[0058] When the water intake of the water supply equipment is in a non-water intake state and the liquid level in the insulation tank is not lower than the middle liquid level, the duration of the non-water intake state is obtained, and it is determined whether it is greater than the preset duration.

[0059] If the duration of the non-water intake state exceeds the preset duration, the water replenishment device will replenish water at the preset maximum water replenishment rate until the liquid level in the insulation tank reaches the high level and then the water replenishment will stop.

[0060] Beneficial effects: When not in use, the liquid level in the insulated tank is not lower than the medium level, and the duration of non-use is longer than the preset duration, indicating that the water intake idle period has been entered. At this time, even if the water temperature drops significantly, water intake will not be affected. Therefore, water can be replenished quickly at the preset maximum replenishment rate until the liquid level in the insulated tank reaches the high level, at which point water replenishment will stop. The insulated tank will be filled during the idle period, reducing the need for water replenishment during the water intake process and further reducing the impact of water replenishment on the water intake process.

[0061] Secondly, the present invention also provides a water replenishment control device for a water supply equipment, comprising:

[0062] The first acquisition module is used to acquire the liquid level inside the insulation tank;

[0063] The first judgment module is used to determine the range of the liquid level;

[0064] The second acquisition module is used to acquire the status of the water intake of the water supply equipment;

[0065] The second judgment module is used to determine whether the water intake state is active.

[0066] The control module is used to control the water replenishment device to start replenishing water when the water intake of the water supply equipment is in the water intake state and the liquid level in the insulation tank is lower than the low liquid level, and to stop replenishing water when the liquid level in the insulation tank reaches the medium liquid level.

[0067] Beneficial effects: The first acquisition module acquires the liquid level in the insulation tank, and the first judgment module determines the range of the liquid level as the basis for water replenishment; then the second acquisition module acquires the status of the water intake of the water supply equipment, and the second judgment module determines whether it is in water intake mode. In water intake mode, water is replenished only when the liquid level in the insulation tank is lower than the low level, and water replenishment is stopped when the medium level is reached. This minimizes the drop in water temperature in the insulation tank caused by water replenishment, ensures a stable water intake flow rate, and avoids fluctuations in water temperature. Since the liquid level is only replenished to the medium level, it can effectively reduce the heating and insulation energy consumption of the insulation tank compared with the method of replenishing it to the full level every time.

[0068] Thirdly, the present invention also provides a computer device, comprising:

[0069] The device includes a memory and a processor, which are interconnected. The memory stores computer instructions, and the processor executes the computer instructions to perform the water replenishment control method of any of the above-described water supply equipment.

[0070] Beneficial effects: The processor executes computer instructions stored in the memory to implement the water replenishment control method of the water supply device of the present invention. When the liquid level in the insulation tank is lower than the low level during water intake, water replenishment is carried out, and water replenishment is stopped when the liquid level reaches the middle level. This minimizes the drop in water temperature in the insulation tank caused by water replenishment, ensures a stable water intake flow rate, and avoids fluctuations in water temperature. Since the liquid level is only replenished to the middle level, the heating and insulation energy consumption of the insulation tank can be effectively reduced compared with the method of replenishing the tank to the full level each time.

[0071] Fourthly, the present invention also provides a computer-readable storage medium storing computer instructions, the computer instructions being used to cause a computer to execute the water replenishment control method of the water supply equipment described in any of the above claims.

[0072] Beneficial effects: By executing computer instructions on a computer-readable storage medium, the computer executes the water replenishment control method of the water supply equipment of the present invention. When the liquid level in the insulation tank is lower than the low liquid level during water intake, water replenishment is carried out, and water replenishment is stopped when the liquid level reaches the middle liquid level. This minimizes the drop in water temperature in the insulation tank caused by water replenishment, ensures a stable water intake flow rate, and avoids fluctuations in water temperature. Since the liquid level is only replenished to the middle liquid level, the heating and insulation energy consumption of the insulation tank can be effectively reduced compared with the method of replenishing the tank to the full level each time.

[0083] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0084] In the description of the invention, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0085] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0086] In view of this, the present invention is proposed.

[0087] The following is combined Figures 1 to 9 The following describes embodiments of the present invention.

[0088] According to an embodiment of the present invention, in one aspect, such as Figure 1 As shown, a water replenishment control method for a water supply device is provided. The water supply device includes an insulated tank, and the water replenishment control method includes:

[0089] Obtain the status of the water intake of the water supply equipment to determine whether it is in water intake mode;

[0090] The liquid level inside the insulation tank is obtained and compared with the preset liquid level, which includes low, medium and high liquid levels; it is then determined whether the liquid level inside the insulation tank is lower than the low liquid level.

[0091] When the water intake of the water supply equipment is in the water intake state and the liquid level in the insulation tank is lower than the low liquid level, the water replenishment device is started to replenish water until the liquid level in the insulation tank reaches the medium liquid level and then the water replenishment stops.

[0092] The preset low liquid level is the water shortage limit level or close to the water shortage limit level. By acquiring the status at the water intake of the water supply equipment, water can be added only when the liquid level in the insulation tank is lower than the low liquid level during water intake. Moreover, water intake stops once the liquid level reaches the middle level, thereby minimizing the drop in water temperature in the insulation tank caused by water intake, ensuring a stable water intake flow rate, and avoiding fluctuations in water temperature. Since the liquid level is only added to the middle level, it can effectively reduce heating and insulation energy consumption compared to filling the tank every time.

[0093] In this embodiment, the preset liquid levels include three types: high, medium, and low. In specific implementations, the liquid level height and the number of liquid level detectors can be adjusted according to the actual product and application scenario. More precise liquid level division can improve the water replenishment control effect. Multiple medium liquid level values ​​of different heights can be set between the high and low liquid levels. Furthermore, the high liquid level can be the highest liquid level limit or a liquid level value near the highest liquid level limit, while the low liquid level can be the lowest liquid level limit or a liquid level value near the lowest liquid level limit; the medium liquid level can be the intermediate value between the high and medium liquid levels, or other values ​​between the high and low liquid levels selected according to the actual application scenario.

[0094] In this embodiment, the liquid level is monitored by a liquid level probe. In some other embodiments, it can also be achieved by other detection tools, such as a liquid level gauge or a liquid level float, to monitor changes in liquid level.

[0095] It should be noted that the water replenishment control method of the water supply equipment of the present invention can be applied to water replenishment of water supply equipment with insulated tanks, such as water purifiers.

[0096] In some embodiments, the control of the water replenishment device to initiate water replenishment includes:

[0097] Obtain the current first water intake rate;

[0098] The first water replenishment rate is determined based on the first water intake rate;

[0099] The water replenishment device is controlled to replenish water at a predetermined first water replenishment rate.

[0100] By obtaining the current water intake rate, the water replenishment rate is determined, and the water replenishment device is controlled to replenish water at the determined rate. This allows for more precise control of the water replenishment rate, ensuring that the water replenishment rate exceeds the water intake rate, thus achieving the goal of continuously raising the water level in the insulation tank during the water intake process.

[0101] In some embodiments, obtaining the current first water intake rate includes:

[0102] The first time it takes for the liquid level to drop from the middle level to the low level is obtained, and the first water intake rate is calculated.

[0103] Alternatively, obtain the monitoring value of the flow meter at the water intake;

[0104] Alternatively, obtain the flow rate curve of the water intake pump to determine the first water intake rate.

[0105] Since the area of ​​the insulated tank is fixed, the liquid level difference between the middle and low liquid levels is also fixed. The volume change can be calculated, and the time it takes for the liquid level to drop from the middle to the low liquid level can be obtained. The ratio of volume change to time is the volumetric flow rate, i.e., the water intake rate. The water intake rate is calculated using the above method, and the feedback is relatively fast. The water intake rate is more accurate by directly monitoring the flow meter at the water intake port. The flow curve of the water pump can be obtained. This flow curve is a static characteristic curve provided by the water pump manufacturer. The flow rate can be estimated based on this flow curve to determine the first water intake rate without the need for sensors.

[0106] In some embodiments, the first water replenishment rate satisfies:

[0107] First water replenishment rate = First water intake rate * K;

[0108] Where K is the adjustment coefficient, and K∈[1.2, 1.5].

[0109] The water replenishment rate and the water intake rate must satisfy the above relationship to ensure that the water replenishment rate can compensate for the water intake rate, and that the liquid level in the insulation tank can rise synchronously while water is being taken out. If the adjustment coefficient is too large, it will cause the water replenishment to be too large, causing the water temperature in the insulation tank to drop too quickly. If the adjustment coefficient is too close to 1, the water replenishment speed will be too slow, which will prolong the user's waiting time.

[0110] In some embodiments, such as Figure 2 As shown, once the liquid level in the insulation tank reaches the middle level, the following steps are also included:

[0111] Continuously monitor the status of the water intake of the water supply equipment to determine whether it is in water intake mode;

[0112] When the water inlet is in the water intake state, the liquid level in the insulation tank is obtained to determine whether the liquid level has dropped to a low level.

[0113] When the liquid level in the insulation tank drops to the low level, the water replenishment device is restarted until the liquid level in the insulation tank rises to the medium level, at which point the water replenishment stops.

[0114] Once the liquid level in the insulation tank reaches the middle level, the system continuously monitors the water intake status and the liquid level in the tank. If the level drops below the low level, water is added; if the level reaches the middle level, water addition stops. This allows for frequent, small-volume water replenishment, ensuring that the water temperature in the insulation tank remains within a relatively small range. This results in faster heating when hot water is drawn, guaranteeing a stable water intake speed for the user and a better user experience.

[0115] In some embodiments, such as Figure 3 As shown, the water replenishment control method further includes:

[0116] If the water inlet is in the water intake state and the liquid level in the insulation tank has not dropped to the low level, no water needs to be added until the water inlet is in the non-water intake state.

[0117] If the liquid level in the insulation tank does not drop to a low level while the water is being drawn, it indicates that there is no water shortage that would affect water drawing. At this time, no water should be added to ensure that the water temperature in the insulation tank does not drop due to water addition and that the water drawing speed is not affected.

[0118] In some embodiments, such as Figure 4 As shown, the water replenishment control method further includes:

[0119] When the water intake of the water supply equipment is not in a water intake state and the liquid level in the insulation tank is lower than the middle liquid level, the water replenishment device will start to replenish water until the liquid level in the insulation tank reaches the middle liquid level and then the water replenishment will stop.

[0120] The medium liquid level is the liquid level between the low and high liquid levels. When the liquid level is higher than the medium liquid level, it indicates that there is enough liquid in the insulation tank, and it can stably supply water for a period of time during the next water intake without the need to add water. When the liquid level is lower than the medium liquid level, water needs to be added to meet the next water intake needs. Adding water only to the medium liquid level can reduce insulation energy consumption and save energy.

[0121] In some embodiments, the control of the water replenishment device to initiate water replenishment includes:

[0122] Obtain the second water intake rate from the previous water intake process;

[0123] The second water replenishment rate is determined based on the second water intake rate;

[0124] The water replenishment device is controlled to replenish water at a determined second water replenishment rate.

[0125] If the liquid level is lower than the middle level when not in water intake mode, it indicates that some water was taken out during the previous water intake process. Therefore, the water replenishment rate should be determined based on the water intake rate of the previous water intake process, and then the water replenishment device should be controlled to replenish water at the determined water replenishment rate. This way, the water replenishment time will be set more reasonably.

[0126] In some embodiments, obtaining the second water intake rate of the previous water intake process includes:

[0127] The second time it takes for the liquid level to drop from the high level to the middle level is obtained, and the second water intake rate is calculated.

[0128] Alternatively, obtain the monitoring value of the flow meter at the water intake;

[0129] Alternatively, obtain the flow rate curve of the water intake pump to determine the second water intake rate.

[0130] Since the water level is either high after being filled or has been replenished to the middle level, a water level below the middle level in a non-water-taking state indicates that the water level dropped from high to below the middle level during the previous water-taking process. Therefore, the volumetric flow rate, i.e., the water-taking rate, can be calculated by combining the time it takes for the water level to drop from high to middle level with the volume change, which is a relatively quick process. Monitoring directly through the flow meter at the water intake port provides a more accurate water-taking rate. Alternatively, the flow curve of the water pump can be obtained, and the flow rate can be estimated based on this curve to determine the first water-taking rate without the need for sensors.

[0131] In some embodiments, the second water replenishment rate satisfies:

[0132] Second water replenishment rate = Second water intake rate * K;

[0133] Where K is the adjustment coefficient, and K∈[1.2, 1.5].

[0134] The water replenishment rate and the water intake rate satisfy the above relationship to ensure that the water replenishment rate can compensate for the water intake rate, and that the liquid level in the insulation tank can rise synchronously while water is being taken out. If the adjustment coefficient is too large, it will cause the water replenishment to be too large, causing the water temperature in the insulation tank to drop too quickly. If the adjustment coefficient is too close to 1, the water replenishment speed will be too slow, which will prolong the user's waiting time and cause a bad experience. When K∈[1.2,1.5], the water temperature in the insulation tank can be prevented from dropping too quickly while ensuring the water replenishment flow rate.

[0135] In some embodiments, such as Figure 5 As shown, the water replenishment control method further includes:

[0136] Obtain the duration of the non-water intake state and determine whether it exceeds the preset duration;

[0137] If the duration of the non-water intake state exceeds the preset duration, the water replenishment device will replenish water at the preset maximum water replenishment rate until the liquid level in the insulation tank reaches the high level and then the water replenishment will stop.

[0138] If the duration of the non-water intake state is longer than the preset duration, it indicates that it is in a water intake idle period. At this time, the water temperature in the cold water insulation tank will drop, but it will not cause a decrease in water output or a slow water output. Therefore, the water replenishment device is directly controlled to replenish water at the preset maximum water replenishment rate until the liquid level in the insulation tank reaches the high level and then the water replenishment stops. The insulation tank is filled with water to reduce the need for water replenishment during the water intake process.

[0139] In some embodiments, such as Figure 6 As shown, when the liquid level in the insulation tank reaches the high level, the following steps are also included:

[0140] Get the water temperature inside the insulated tank and determine whether it has dropped to the first preset water temperature;

[0141] When the water temperature in the insulation tank has dropped to the first preset water temperature, the heating device is activated to heat the water until the water temperature in the insulation tank rises to the second preset water temperature and then heating stops.

[0142] After the insulated tank is filled with water, the water temperature inside the tank is measured to determine whether heating is needed. If the water temperature is lower than the first preset water temperature, it indicates that the water temperature inside the insulated tank is low. If it is not preheated, the heating time during water dispensing will be prolonged, and the water temperature will also be prone to fluctuations. Therefore, heating is carried out when the water temperature is lower than the first preset water temperature until the water temperature inside the insulated tank rises to a more suitable second preset water temperature. If it is higher than the second preset water temperature, it will increase energy consumption too much.

[0143] In some embodiments, the water replenishment control method further includes:

[0144] When the water intake of the water supply equipment is in a non-water intake state and the liquid level in the insulation tank is not lower than the middle liquid level, the duration of the non-water intake state is obtained, and it is determined whether it is greater than the preset duration.

[0145] If the duration of the non-water intake state exceeds the preset duration, the water replenishment device will replenish water at the preset maximum water replenishment rate until the liquid level in the insulation tank reaches the high level and then the water replenishment will stop.

[0146] If the liquid level in the insulated tank is not lower than the medium level when not in use, and the duration of the non-water-taking state is longer than the preset duration, it indicates that the water-taking idle period has been entered. At this time, even if the water temperature drops significantly when water is added, it will not affect the water-taking process. Therefore, water can be added quickly at the preset maximum water-addition rate until the liquid level in the insulated tank reaches the high level, and then water-addition can be stopped. The insulated tank can be filled during the idle period to reduce water-addition during the water-taking process and further reduce the impact of water-addition on the water-taking process.

[0147] In some other embodiments, unlike the previous embodiment, the idle water period can be directly integrated into the control module of the water supply equipment. For example, the period from 0:00 to 5:00 AM can be defined as the idle period. When the idle period is reached, water is automatically replenished until the liquid level in the insulation tank reaches the high level, at which point replenishment stops. Since this period falls during people's sleep, users are unlikely to collect water, so the replenishment rate may not necessarily be at the preset maximum replenishment rate.

[0148] This invention provides a method for controlling the water level replenishment in a heated water purifier with an insulated tank. The heated water purifier includes an insulated tank, a water replenishment pump, a water intake pump, and a level probe. The insulated tank must ensure that the water level and temperature meet usage requirements. In this embodiment, heating is initiated when the water temperature in the insulated tank is below 40°C, and heating is stopped when it exceeds 60°C, maintaining the water temperature between 40°C and 60°C. The water replenishment pump draws cold water from outside into the insulated tank. The flow rate of the water replenishment pump can be adjusted using basic control methods, such as a controller outputting control signals with different duty cycles (0%~100%), allowing the pump flow rate to be controlled between 0% and 100%. The level probe detects the water level in the insulated tank. For example, if the insulated tank capacity is 1.5L, the low level probe is set at 0.5L, the medium level probe at 1L, and the high level probe at 1.5L (the probe positions can be adjusted according to different products).

[0149] In this embodiment, the water replenishment strategy is dynamically adjusted by detecting the liquid level and the user's water intake behavior, which are divided into two water replenishment situations: water intake and non-water intake.

[0150] During water intake, continuously monitor the water level in the insulation tank. If the water level changes from medium to low during water intake, first calculate the water intake rate, and then calculate the water replenishment rate based on the water intake rate multiplied by the adjustment coefficient. The adjustment coefficient is usually 1.2-1.5 to ensure that the water replenishment rate is slightly higher than the water intake rate.

[0151] In non-water-dispensing mode, if the water level is below the middle level, it will be replenished to the middle level at the intelligent replenishment rate. Compared to directly filling the tank, this ensures a sufficient water level for the next water dispensing, while also reducing the amount of cold water needed and saving energy. This is because replenishing with cold water causes a drop in water temperature; if the temperature falls below the set temperature, the insulation tank will need to activate heating. If the non-water-dispensing state continues for X minutes (e.g., 60 minutes), it is considered that the peak water dispensing period has not occurred, and the system enters the low-peak replenishment mode, replenishing water to the high level at the maximum pump rate, and activating heating according to temperature conditions.

[0152] Because the insulated tank is filled with a small amount of water each time, it saves energy consumption during the heating and insulation process. At the same time, it avoids sudden drops in water temperature, ensuring smooth water dispensing for users. When dispensing water, the water in the insulated tank enters the heating element and is heated to the user's set temperature before being taken out. If the inlet water temperature suddenly drops, the user's water dispensing rate will decrease accordingly.

[0153] When drawing water, if the level is below the low level, water is replenished to the medium level at the intelligent replenishment rate. When not drawing water, if the level is below the medium level, water is replenished to the medium level to facilitate the calculation of the replenishment rate. If no water is drawn again after 60 minutes, it indicates that it is not during the peak water drawing period, and water can be replenished to the high level at the maximum rate.

[0154] The water replenishment control method of this invention replenishes the insulation tank to the middle liquid level during water replenishment, ensuring normal water intake while minimizing temperature changes within the insulation tank caused by water replenishment. This reduces fluctuations in the water intake flow rate and the frequency of heating in the insulation tank. For products replenished at a fixed flow rate, the water replenishment rate is set relatively high to prevent insufficient replenishment and water shortage due to a lower water intake flow rate.

[0155] When a thermal container is quickly filled, its temperature will fluctuate significantly. For example, if a 2L thermal container contains 500ml of 50℃ hot water and 1500ml of 25℃ cold water is added, the temperature will drop from 50℃ to around 30℃ after filling.

[0156] This invention also avoids excessive water replenishment after each water draw, which would lead to excessive energy consumption in order to maintain the water temperature. It is suitable for household use scenarios where the frequency and amount of hot water drawn are relatively low (scenarios where a large amount of hot water is not needed in a short period of time).

[0157] The water replenishment control method has a simple control logic and can maintain the relative stability of the water level and temperature in the storage tank, thereby improving the user experience and reducing energy waste.

[0158] According to an embodiment of the present invention, in another aspect, a water replenishment control device for a water supply equipment is also provided, comprising:

[0159] The first acquisition module is used to acquire the liquid level inside the insulation tank;

[0160] The first judgment module is used to determine the range of the liquid level;

[0161] The second acquisition module is used to acquire the status of the water intake of the water supply equipment;

[0162] The second judgment module is used to determine whether the water intake state is active.

[0163] The control module is used to control the water replenishment device to start replenishing water when the water intake of the water supply equipment is in the water intake state and the liquid level in the insulation tank is lower than the low liquid level, and to stop replenishing water when the liquid level in the insulation tank reaches the medium liquid level.

[0164] The first acquisition module acquires the liquid level in the insulation tank, and the first judgment module determines the range of the liquid level as the basis for water replenishment. Then, the second acquisition module acquires the status of the water intake of the water supply equipment, and the second judgment module determines whether it is in water intake mode. When water intake mode is in effect, water is replenished only when the liquid level in the insulation tank is lower than the low level, and water replenishment is stopped when the medium level is reached. This minimizes the drop in water temperature in the insulation tank caused by water replenishment, ensures a stable water intake flow rate, and avoids fluctuations in water temperature. Since the liquid level is only replenished to the medium level, it can effectively reduce the heating and insulation energy consumption of the insulation tank compared to replenishing it to the full level each time.

This minimizes the drop in water temperature in the insulation tank caused by water replenishment, ensures a stable water intake flow rate, and avoids fluctuations in water temperature. Since the liquid level is only replenished to the middle level, the heating and insulation energy consumption of the insulation tank can be effectively reduced compared to the method of replenishing the tank completely each time.
