Description

Technical Field

[0001] This application belongs to the field of liquid heating, and more specifically, relates to a liquid handling system and its control method, control device, and readable storage medium. Background Technology

[0002] In daily life, people have a habit of drinking cooled boiled water. Modern instant water heaters can quickly heat water. However, according to electrical safety regulations, the maximum power of household tabletop water dispensers is limited to 2300W. Theoretically, in a direct drinking water dispenser scenario, this power can heat room temperature water (7.3g / s) to boiling. However, due to losses in electric heating efficiency and heat energy utilization, the current water flow rate of direct drinking water dispensers is typically less than 6.5g / s. This results in a low water flow rate in existing tabletop water dispensers and similar products, making them prone to flow interruptions and thus affecting the user experience.

[0003] Therefore, designing a new liquid treatment system capable of producing large volumes of water has become an urgent problem to be solved. Summary of the Invention

[0004] The present invention aims to solve or improve at least one of the above-mentioned technical problems.

[0005] A first aspect of the present invention is to provide a control method for the above-described liquid handling system.

[0006] A second aspect of the present invention is to provide a control device for a liquid handling system.

[0007] A third aspect of the invention is to provide a control device for another liquid handling system.

[0008] A fourth aspect of the present invention is to provide a readable storage medium.

[0009] A fifth aspect of the present invention is to provide a liquid handling system.

[0010] The first aspect of the present invention provides a control method for a liquid processing system. The liquid processing system includes a preheating component and a heating component. The preheating component is used to store heat and can use the stored heat to preheat the liquid that has passed through the preheating component. The heating component is used to reheat the liquid that has been preheated by the preheating component. The control method includes: during the liquid discharge process, obtaining the temperature of the liquid that has been preheated by the preheating component; and controlling the heating power of the heating component and the heat storage power of the preheating component according to the temperature range of the preheated liquid temperature.

[0011] The liquid treatment system provided by the present invention can detect the temperature of the preheating component after preheating, and then determine the heating power of the heating component and the heat storage power of the preheating component based on the temperature range. In this way, the heat storage power of the preheating component can be dynamically adjusted so that the preheating component can store heat in a timely manner when the preheating effect is good, thereby extending the preheating time of the preheating component and ensuring a large flow of water for a long time. At the same time, when the preheating effect of the preheating component is poor, the preheating component can stop storing heat, allowing the heating component to heat at full power. This can maximize the large flow of water and ensure that the water heated by the heating component can reach the target temperature such as boiling.

[0012] In the above technical solution, the step of controlling the heating power of the heating component and the heat storage power of the preheating component according to the temperature range of the preheated liquid includes: when the preheated liquid temperature is greater than or equal to the full-load charging temperature, allocating a first power to the preheating component for heat storage, wherein the first power is greater than or equal to the rated charging power of the preheating component.

[0013] In this technical solution, when the preheated liquid temperature is greater than or equal to the full-load charging temperature, it indicates that the preheating effect of the preheating component is relatively good. At this time, the heating demand of the heating component is not high, so a higher power can be allocated to the preheating component for heat storage. Specifically, the power allocated to the preheating component in this stage is generally greater than the rated charging power of the preheating component, while the power allocated to the heating component is not high. That is, in this stage, the preheating component can store heat at its maximum power at any time according to its own situation, to ensure that the preheating component can store heat in a timely manner and ensure that the preheating effect of the preheating component can remain in a relatively good state for a long time, thereby extending the duration of the preheating component in the high-efficiency preheating stage.

[0014] In the above technical solution, the step of controlling the heating power of the heating component and the heat storage power of the preheating component according to the temperature range of the preheated liquid temperature further includes: when the preheated liquid temperature is less than the full-load charging temperature and greater than the deceleration critical temperature, the preheating component stores heat with a second power, the second power is less than the rated charging power of the preheating component, the second power is negatively correlated with the preheated liquid temperature, or the second power is a constant value.

[0015] In this technical solution, when the preheated liquid temperature falls within the range of the full-load charging temperature to the deceleration critical temperature, it indicates that the preheating effect of the preheating component is no longer optimal. However, its preheating effect still does not require the heating component to operate at full power. Therefore, at this stage, a certain power can be allocated to the preheating component to allow it to continue storing heat. However, this power cannot be too high, exceeding the rated charging power; otherwise, the heating component will not be able to heat the water effectively. Simultaneously, at this stage, the value of the second power can be set to different values ​​as needed. Specifically, the higher the preheated temperature, the smaller the allocated second power should be; that is, the second power is negatively correlated with the preheated liquid temperature. In practice, a correlation table between temperature and preheating component power allocation can be established to allocate the corresponding power value to the preheating component within the corresponding temperature range for preheating. Of course, at this stage, the second power can also be a fixed value.

[0016] In another technical solution, the step of controlling the heating power of the heating component and the heat storage power of the preheating component according to the temperature range of the preheated liquid temperature further includes: when the preheated liquid temperature is less than the full-load charging temperature and greater than the deceleration critical temperature, the heating component heats with a first power and allocates a second power to the preheating component for heat storage. The second power is equal to the target power minus the first power, and the first power is less than the full power of the heating component.

[0017] In this technical solution, when the preheated liquid temperature falls within the range of the full-load charging temperature to the critical temperature for rate reduction, it indicates that the preheating effect of the preheating component is no longer optimal. However, its preheating effect still does not require the heating component to operate at full power. Therefore, at this stage, a certain amount of power can be allocated to the preheating component to allow it to continue storing heat. However, to ensure a large flow rate of water output, the power requirements of the heating component must be prioritized, and the preheating component can only store heat using its remaining power. That is, at this stage, it is not necessary to reduce the liquid flow rate; only the power of the heating component needs to be increased, while the available power of the preheating component is reduced. This maximizes the duration of high-flow-rate water output and maximizes the utilization of the remaining power to preheat the preheating component, thereby extending its preheating effect.

[0018] In the above technical solution, the full-load charging temperature is greater than or equal to 58℃ and less than or equal to 69℃. The full-load charging temperature is a transition temperature, i.e., the temperature at which the liquid flow rate needs to maintain the initial flow rate. Therefore, this temperature should not be set too high, because if the temperature is too high, the time for maintaining the initial flow rate will be too short, making it impossible to achieve a larger flow rate. At the same time, this temperature should not be too low either; otherwise, the time spent maintaining the initial flow rate will be too long, resulting in excessive energy consumption. This would lead to a short transition time for the liquid flow rate to switch from the initial flow rate to the set flow rate, causing excessively abrupt changes in flow rate. In other words, the flow rate cannot smoothly transition from the initial flow rate to the set flow rate, which can easily lead to unstable water output and thus reduce the user experience.

[0019] In the above technical solution, the critical temperature for slowing down is greater than or equal to 38℃ and less than or equal to 55℃. The critical temperature for slowing down needs to be designed in conjunction with the characteristics of the product itself. Considering the characteristics of the preheating component and the preset flow rate, setting the critical temperature for slowing down between 38℃ and 55℃ is more reasonable, thereby improving the compatibility of the internal components of the product.

[0020] In the above technical solution, the liquid temperature after preheating by the preheating component is equal to the rate-deceleration critical temperature. When the heating component operates at full power and the liquid flows through it at a set flow rate, the outlet temperature of the heating component is equal to the preset target outlet temperature. That is, the rate-deceleration critical temperature is the minimum temperature required to heat water to boiling point at the set flow rate. Therefore, if the preheating component cannot preheat the water to this temperature, it cannot be heated to boiling point.

[0021] In the above technical solution, the step of controlling the heating power of the heating component and the heat storage power of the preheating component according to the temperature range of the preheated liquid further includes: when the preheated liquid temperature is less than or equal to the deceleration critical temperature and greater than or equal to the system ambient temperature, the heating component heats at full power and the heat storage power of the preheating component is 0; when the preheated liquid temperature is less than the system ambient temperature, the heating component heats at full power and the heat storage power of the preheating component is 0.

[0022] In this technical solution, when the preheated liquid temperature equals the critical temperature for slowing down, the heating component needs to operate at full power to maintain the current preset high flow rate. However, when the preheating temperature falls further below the critical temperature for slowing down, even with full power, the heating component cannot heat the set high flow rate liquid to the target temperature, such as boiling, thus necessitating a reduction in flow rate. During this stage, due to insufficient preheating efficiency, the preheating component stops storing heat, and the heating component operates at full power to maximize the water output. Of course, in the stage where the preheated liquid temperature is below the critical temperature for slowing down but above the system ambient temperature, the preheating component can still have a certain heat storage capacity, but the liquid flow rate needs to be reduced accordingly. In other words, during this stage, the heat storage capacity can be determined based on the actual flow rate of the liquid passing through the heating component. When the preheated temperature falls below the system ambient temperature, the preheating component must stop storing heat, and the heating component must operate at full power because the flow rate is generally at a normal flow rate at this stage, and the liquid velocity itself is relatively slow, making further reduction in flow rate unsuitable.

[0023] In any of the above technical solutions, the control method further includes: responding to a heating command to obtain the temperature of the preheating component; determining the initial liquid volume passing through the heating component based on the temperature of the preheating component; or responding to a heating command to control the liquid to pass through the heating component at a set flow rate.

[0024] In this technical solution, two options can be chosen when determining the initial liquid volume. The first option is to first obtain the temperature of the preheating component after receiving the heating command, thereby determining the state of the preheating component, that is, determining the preheating efficiency of the preheating component. Then, the initial flow rate is determined based on the actual preheating efficiency of the preheating component. In other words, the state of the preheating component is related to the initial flow rate. This makes the initial liquid volume more reasonable, avoiding the situation where the initial liquid volume is too large and the liquid cannot be boiled, or the initial liquid volume is too small and cannot meet the large flow rate requirement.

[0025] In another approach, upon receiving a heating command, the liquid is directly heated through the heating component at a set flow rate, meaning the initial liquid volume is the set flow rate, or a preset high flow rate. After heating begins, the preheated liquid temperature is detected by the preheating component, and the actual flow rate is controlled based on the detected temperature range. This approach, however, does not consider the actual state of the preheating component when determining the initial liquid volume, making the initial volume determination relatively convenient and the control logic simpler, thus making the product's control method easier to implement.

[0026] Further, the step of determining the initial liquid volume passing through the heating component based on the temperature of the preheating component includes: when the temperature of the preheating component is greater than or equal to a second temperature value, controlling the liquid to pass through the heating component at a set flow rate; when the temperature of the preheating component is less than or equal to the second temperature value but greater than a first temperature value, controlling the liquid to pass through the heating component at a first flow rate, the first flow rate being greater than the set flow rate; and when the temperature of the preheating component is less than the first temperature value, controlling the liquid to pass through the heating component at a second flow rate, the second flow rate being less than the set flow rate.

[0027] In this technical solution, the initial liquid volume passing through the heating component can be determined by comparing the temperature of the preheating component with the first and second temperature values. When the temperature of the preheating component is greater than the second temperature value, it indicates that the preheating component is basically in a state of heat storage saturation, i.e., fully charged. Therefore, heating can be carried out at a set flow rate to achieve the preset large flow rate of water output. When the temperature of the preheating component is less than the first temperature value but greater than the second temperature value, the first flow rate (generally less than the set flow rate) is used as the initial liquid volume for output to ensure that the initial liquid volume is moderate, since there is still a certain preheating effect at this stage. When the temperature of the preheating component is less than the first temperature value, the second flow rate is used as the initial liquid volume for output. The second flow rate is basically equal to the conventional flow rate without a preheating component, generally around 6.5 g / s, which ensures that the liquid can be heated to the target output temperature, such as boiling.

[0028] Specifically, the second temperature value is the temperature at which the preheating component completes energy storage, that is, the temperature of the phase change material after the preheating component completes heat storage, and the second temperature value is greater than or equal to 80℃ and less than or equal to 100℃.

[0029] The initial temperature value is generally greater than or equal to 40℃ and less than or equal to 60℃. This value can be set according to actual conditions, but it should not be too high or too low. If it is too high, the preheating effect will be good, but the initial flow rate will be small, which does not meet the high flow rate requirement of this product. If it is too low, it will lead to insufficient preheating capacity, resulting in an excessive flow rate and failure to heat the water to boiling.

[0030] In any of the above technical solutions, the control method further includes one or more of the following steps: when the preheated liquid temperature is greater than or equal to the full-load charging temperature, the liquid is controlled to pass through the heating component at a first flow rate, the first flow rate being greater than or equal to a set flow rate; when the preheated liquid temperature is less than the full-load charging temperature but greater than or equal to the deceleration critical temperature, the liquid is controlled to pass through the heating component at a set flow rate; when the preheated liquid temperature is less than the deceleration critical temperature but greater than or equal to the system ambient temperature, the flow rate of the liquid through the heating component is made less than or equal to the set flow rate but greater than a second flow rate; when the preheated liquid temperature is less than or equal to the system ambient temperature, the liquid is controlled to pass through the heating component at a second flow rate, the second flow rate being less than the set flow rate.

[0031] In this technical solution, the preheated temperature is initially divided into four stages based on the full-load charging temperature, the critical rate-dropping temperature, and the system ambient temperature. The flow rate decreases sequentially in each of these four stages. Specifically, in the temperature range above the full-load charging temperature, the flow rate is the first velocity, which is relatively high and can meet the requirements for large-flow-rate water output. In the range between the full-load charging temperature and the critical rate-dropping temperature, the flow rate is the set velocity, also belonging to the large-flow-rate water output stage. In the range between the critical rate-dropping temperature and the system ambient temperature, the flow rate is between the set velocity and the second velocity, and can be a fixed value or a value that dynamically changes with temperature. When the preheated temperature is below the system ambient temperature, the flow rate is the normal flow rate, i.e., the second velocity. This solution, during actual liquid dispensing, rationally controls the flow rate of the liquid through the heating element based on the temperature range of the liquid after preheating by the preheating component. In other words, it adjusts the flow rate according to the actual preheating state of the preheating component, avoiding both insufficient liquid temperature due to consistently high preheating flow and insufficient flow rate due to consistently low preheating flow. Through this adjustment, a high flow rate can be dispensed when the preheating effect is good, and the flow rate can be reduced in time when the preheating effect is poor to ensure the desired liquid temperature. This maximizes both the preset high flow rate and the required liquid temperature, thus achieving high flow rate control and improving the user experience.

[0032] Furthermore, when the preheated liquid temperature is less than the deceleration critical temperature but greater than or equal to the system ambient temperature, and / or when the preheated liquid temperature is greater than or equal to the full-load charging temperature, the flow rate of the liquid through the heating component is positively correlated with the preheated liquid temperature.

[0033] In this technical solution, the liquid flow rate varies across different temperature ranges after preheating. Within each specific temperature range, the flow rate can be adjusted according to the temperature. For example, when the preheated liquid temperature falls within the range of the critical temperature drop threshold and the system ambient temperature, the flow rate can gradually decrease from a set flow rate to a second flow rate. Alternatively, a temperature-flow rate curve can be set for each temperature range, and the specific heating flow rate can be set according to the corresponding temperature. Furthermore, when the preheated liquid temperature is higher than the full-load charging temperature, the higher the temperature, the higher the flow rate. Generally, after the temperature exceeds the set temperature T4, heating is performed at a fixed flow rate value; that is, the first flow rate is also a variable value. Specifically, in the range where the preheated temperature exceeds the set temperature T4, the first flow rate is a first fixed value. In the range where the preheated temperature is lower than the set temperature T4 but higher than the full-load charging temperature, the first flow rate gradually decreases from the first fixed value to a second fixed value (generally the set flow rate value).

[0034] Furthermore, the flow rate is set to be greater than or equal to 9 g / s and less than or equal to 15 g / s. That is, the rated flow rate of the liquid passing through the heating component is 9 g / s-15 g / s.

[0035] In any of the above technical solutions, the control method further includes: controlling the preheating component to store heat when the liquid handling system is in a non-heating state. Alternatively, if the liquid handling system includes a non-heating state, the control method further includes: in the non-heating state, controlling the preheating component to store heat with a first heat storage power, and after the heat storage is completed, maintaining the temperature with a second heat storage power, wherein the first heat storage power is greater than the second heat storage power.

[0036] In these technical solutions, the liquid handling system includes a non-heating state, i.e., an idle state when the user is not dispensing liquid. In this state, the preheating component heats at full power (first heat storage power) using its set maximum power to quickly accumulate heat. After accumulating enough heat, it can reduce its power to a second heat storage power for heat preservation. This ensures that the preheating component can remain in a state of full heat storage for a long time, thereby ensuring that when the user needs liquids such as water, the preheating component can promptly preheat the liquid to the required temperature.

[0037] In any of the above technical solutions, the control method further includes: in response to a preset time during startup, putting the liquid handling system into a state where heating is prohibited, and causing the preheating component to perform full-power heat storage.

[0038] In these technical solutions, when the liquid handling system is first started, the preheating components do not have enough time to store heat. Therefore, for a short period after startup, it is generally unable to meet the requirements for large-flow liquid discharge. Thus, a startup protection period is set, during which the liquid handling system is in a state of no-discharge (no-heating) to allow the preheating components time to store heat. This preset time is reasonably set based on the time required for the preheating components to reach saturation. During this stage, the preheating components can operate at full power for rapid heat storage to quickly reach saturation.

[0039] In any of the above technical solutions, the control method further includes: when a heating command is received, determining whether the preheating component is at the heat preservation power or whether the preheating component is in the heat storage saturation state; when the preheating component is at the heat preservation power or in the heat storage saturation state, controlling normal liquid discharge; when the preheating component is not at the heat preservation power or not in the heat storage saturation state, prohibiting liquid discharge or reducing the liquid discharge rate and making the liquid temperature output by the heating component greater than the preset target temperature.

[0040] In this technical solution, when a liquid dispensing command is detected, the system first determines whether the preheating component has completed heat storage. For example, if it is in a heat preservation state, heat storage is complete. Alternatively, the temperature of the preheating component can be directly detected to determine if it has reached saturation. If so, it indicates that the preheating component has sufficient heat storage to meet the preset high-flow-rate liquid dispensing requirement. In this case, the normal procedure can be followed, first obtaining the preset temperature parameter and then adjusting the dispensing rate. Conversely, if the preheating component is not saturated, i.e., insufficient heat storage is detected, then when preparing to dispense liquid, the preset temperature parameter is not compared. Instead, the dispensing rate is directly limited or reduced, and the liquid temperature output by the heating component is made higher than the preset target temperature. This simplifies the entire control process, as insufficient heat storage in the preheating component generally cannot meet the set high-flow-rate liquid dispensing requirement. Therefore, to improve control efficiency, temperature-related judgments are not performed. For example, during long-term dispensing or when the interval between consecutive dispensing is short, temperature detection can be omitted, and the dispensing rate can be directly limited or reduced to ensure that the output liquid meets the target dispensing requirement.

[0041] The second aspect of the present invention provides a control device for a liquid processing system. The liquid processing system includes a preheating component and a heating component. The preheating component is used to store heat and can use the stored heat to preheat the liquid that has passed through the preheating component. The heating component is used to reheat the liquid that has been preheated by the preheating component. The control device includes: an acquisition unit for acquiring the temperature of the liquid that has been preheated by the preheating component during the liquid discharge process; and a control unit for controlling the heating power of the heating component and the heat storage power of the preheating component according to the temperature range of the preheated liquid.

[0042] Furthermore, the control device is also used in the steps of the control method for the liquid handling system provided by any of the technical solutions in the first aspect.

[0043] The control device for the liquid handling system provided by the present invention, since it is a device corresponding to the control method for the liquid handling system provided by any of the technical solutions of the first aspect, also has the effect corresponding to the control method for the liquid handling system provided by any of the technical solutions of the second aspect, which will not be described again here.

[0044] The third aspect of the present invention provides a control device for a liquid handling system, including a memory and a processor. The memory stores a program or instructions that can be executed on the processor. When the program or instructions are executed by the processor, they implement the steps of the control method for the liquid handling system provided by any of the first aspects.

Detailed Implementation

[0061] To better understand the above aspects, features, and advantages of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0062] Many specific details are set forth in the following description in order to provide a full understanding of the embodiments of the present invention. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the embodiments of the present invention is not limited to the specific embodiments disclosed below.

[0063] The following reference Figures 1 to 10 This application describes the liquid handling system and its control method and control device provided.

[0064] Example 1

[0065] like Figure 1 As shown, the control method for a liquid handling system provided in the first aspect of the present invention is used for, as Figures 1 to 3 The liquid handling system shown includes a preheating component 2 and a heating component 3. The preheating component 2 stores heat and can use the stored heat to preheat the liquid passing through it. The heating component 3 is used to reheat the liquid preheated by the preheating component 2. Figure 4 As shown, the control methods include:

[0066] S402, during the liquid discharge process, obtains the temperature of the liquid after preheating by the preheating component;

[0067] S404 controls the heating power of the heating component and the heat storage power of the preheating component according to the temperature range of the preheated liquid.

[0068] The liquid handling system provided by the present invention includes a preheating component and a heating component. Specifically, the liquid handling system can be a desktop water dispenser, or more specifically, a desktop direct-drinking water dispenser, that is, a water dispenser that directly outputs boiled liquid or boiled liquid adjusted to a suitable drinking temperature before outputting. Specifically, the preheating component is connected to the liquid supply port, etc., and its purpose is to accumulate heat when the user is not using water or other liquids, i.e., in a non-heating state. Then, when the user needs water or other liquids, the pre-stored energy is used to preheat the liquid supplied by the liquid supply port, etc., to a certain temperature. The preheated liquid then enters the heating component and is rapidly heated to boiling. The boiled liquid is discharged through the liquid outlet component, or the boiled liquid can also undergo heat exchange or be combined with other liquids before being discharged. This scheme can detect the temperature of the preheating component after preheating, and then determine the heating power of the heating component and the heat storage power of the preheating component based on the temperature range. This allows for dynamic adjustment of the heat storage power of the preheating component, enabling it to store heat in a timely manner when the preheating effect is good, thereby extending the preheating time and ensuring a large flow of water for a long time. Conversely, when the preheating effect is poor, the preheating component can stop storing heat, allowing the heating component to heat at full power. This maximizes the guarantee of a large flow of water and ensures that the water heated by the heating component reaches the target temperature such as boiling.

[0069] In the above embodiment, S404 specifically includes: when the preheated liquid temperature is greater than or equal to the full-load charging temperature T3, allocating a first power to the preheating component for heat storage, wherein the first power is greater than or equal to the rated charging power of the preheating component.

[0070] In this embodiment, when the preheated liquid temperature is greater than or equal to the full-load charging temperature T3, it indicates that the preheating effect of the preheating component is relatively good. At this time, the heating demand of the heating component is not large, so a higher power can be allocated to the preheating component for heat storage. Specifically, the power allocated to the preheating component in this stage is generally greater than the rated charging power of the preheating component, while the power allocated to the heating component is not much. That is, in this stage, the preheating component can store heat at its maximum power at any time according to its own situation, to ensure that the preheating component can store heat in a timely manner and ensure that the preheating effect of the preheating component can remain in a relatively good state for a long time, thereby extending the duration of the preheating component in the high-efficiency preheating stage.

[0071] In the above embodiment, S404 further includes: when the preheated liquid temperature is less than the full-load charging temperature T3 and greater than the deceleration critical temperature T1, the preheating component stores heat with a second power, the second power is less than the rated charging power of the preheating component, the second power is negatively correlated with the preheated liquid temperature, or the second power is a constant value.

[0072] In this embodiment, when the preheated liquid temperature falls within the range of the full-load charging temperature T3 to the deceleration critical temperature T1, it indicates that the preheating effect of the preheating component is no longer optimal. However, its preheating effect still does not require the heating component to operate at full power. Therefore, at this stage, a certain power can be allocated to the preheating component to allow it to continue storing heat. However, this power cannot be too high and cannot exceed the rated charging power; otherwise, the heating component will not be able to heat the water effectively. Simultaneously, at this stage, the value of the second power can be set to different values ​​as needed. Specifically, the higher the preheated temperature, the smaller the allocated second power should be; that is, the second power is negatively correlated with the preheated liquid temperature. In practice, a correlation table between temperature and preheating component power allocation can be set up so that the corresponding power value is allocated to the preheating component for preheating within the corresponding temperature range. Of course, at this stage, the second power can also be a fixed value.

[0073] In another embodiment, the step of controlling the heating power of the heating component and the heat storage power of the preheating component according to the temperature range of the preheated liquid temperature further includes: when the preheated liquid temperature is less than the full-load charging temperature T3 and greater than the deceleration critical temperature T1, the heating component heats with a first power and allocates a second power to the preheating component for heat storage, the second power being equal to the target power minus the first power and the first power being less than the full power of the heating component.

[0074] In this embodiment, when the preheated liquid temperature falls within the range of the full-load charging temperature T3 to the critical deceleration temperature T1, it indicates that the preheating effect of the preheating component is no longer optimal. However, its preheating effect still does not require the heating component to operate at full power. Therefore, at this stage, a certain amount of power can be allocated to the preheating component to allow it to continue storing heat. However, to ensure a large flow rate of water output, the power requirements of the heating component must be prioritized, and the preheating component can only store heat using its remaining power. That is, at this stage, it is not necessary to reduce the liquid flow rate; only the power of the heating component needs to be increased, while the available power of the preheating component is reduced. This maximizes the duration of the large flow rate of water output and maximizes the use of the remaining power to preheat the preheating component, thereby extending its preheating effect.

[0075] In the above embodiment, the full-load charging temperature T3 is greater than or equal to 58°C and less than or equal to 69°C. The full-load charging temperature T3 is a transition temperature, i.e., the temperature at which the liquid flow rate needs to maintain the first flow rate. Therefore, this temperature should not be set too high, because if the temperature is too high, the time for maintaining the first flow rate will be too short, making it impossible to achieve a larger flow rate. At the same time, this temperature should not be too low either; otherwise, the time for maintaining the first flow rate will be too long, resulting in excessive energy consumption. This would lead to a short transition time for the liquid flow rate to switch from the first flow rate to the set flow rate, resulting in a sudden change in flow rate. In other words, the flow rate cannot smoothly transition from the first flow rate to the set flow rate, which can easily lead to unstable water output and thus reduce the user experience.

[0076] In the above embodiments, the critical temperature for slowing down is greater than or equal to 38°C and less than or equal to 55°C. The critical temperature for slowing down needs to be designed in conjunction with the characteristics of the product itself. Considering the characteristics of the preheating component and the preset flow rate, setting the critical temperature for slowing down T1 between 38°C and 55°C is more reasonable, thereby improving the compatibility of the internal components of the product.

[0077] In the above embodiment, the liquid temperature after preheating by the preheating component is equal to the rate-deceleration critical temperature T1. When the heating component heats at full power and the liquid passes through the heating component at a set flow rate, the liquid outlet temperature of the heating component is equal to the preset target outlet temperature. That is, the rate-deceleration critical temperature T1 is the minimum temperature value required to heat water to boiling point at the set flow rate. Therefore, if the preheating component cannot preheat the water to this temperature, the water cannot be heated to boiling point.

[0078] In the above embodiment, S404 further includes: when the liquid temperature after preheating by the preheating component is less than or equal to the deceleration critical temperature T1 and greater than or equal to the system ambient temperature T2, the heating component heats at full power and the heat storage power of the preheating component is 0; when the liquid temperature after preheating by the preheating component is less than the system ambient temperature T2, the heating component heats at full power and the heat storage power of the preheating component is 0.

[0079] In this embodiment, when the preheated liquid temperature equals the rate-deceleration critical temperature T1, the heating component needs to operate at full power to maintain the current preset high flow rate. However, when the preheated temperature falls further below the rate-deceleration critical temperature T1, even with full power, the heating component cannot heat the set high flow rate liquid to the target temperature, such as boiling, thus necessitating a reduction in flow rate. During this stage, due to insufficient preheating efficiency, the preheating component stops storing heat, and the heating component operates at full power to maximize water output. Of course, when the preheated liquid temperature is below the rate-deceleration critical temperature T1 but above the system ambient temperature, the preheating component can still have a certain heat storage capacity, but the liquid flow rate needs to be reduced accordingly. In other words, during this stage, the heat storage capacity can be determined based on the actual flow rate of the liquid passing through the heating component. When the preheated temperature falls below the system ambient temperature T2, the preheating component must stop storing heat, and the heating component must operate at full power. This is because during this stage, the flow rate is generally at a normal flow rate, and the liquid velocity itself is relatively slow, making further reduction in flow rate unsuitable.

[0080] In this application, the parameters such as the full-load charging temperature T3, the deceleration critical temperature T1, and the system ambient temperature T2 can be set to a fixed value as needed. However, considering the fluctuations during temperature measurement, their values ​​are generally within a range. Generally speaking, the range of the full-load charging temperature T3, the deceleration critical temperature T1, and the system ambient temperature T2 is a reference value ± a fluctuation threshold, which is generally greater than or equal to 2℃ and less than or equal to 6℃.

[0081] Example 2, as Figure 5 As shown, this embodiment specifically includes the following steps:

[0082] S502, responding to a heating command, obtains the temperature of the preheating component; determines the initial liquid volume passing through the heating component based on the temperature of the preheating component; or responds to a heating command, controls the liquid to pass through the heating component at a set flow rate.

[0083] Based on the temperature range of the preheated liquid temperature T, determine the heating power of the heating element and the heat storage power of the preheating element, specifically including:

[0084] S504, when the preheated liquid temperature is greater than or equal to the full-load charging temperature T3, the first power is allocated to the preheating component for heat storage, and the first power is greater than or equal to the rated charging power of the preheating component.

[0085] S506, when the preheated liquid temperature is less than the full-load charging temperature T3 and greater than the deceleration critical temperature T1, the heating component heats with the first power and allocates the second power to the preheating component for heat storage. The second power is equal to the target power minus the first power and the remaining power. The first power is less than the full power of the heating component.

[0086] S508, when the liquid temperature after preheating by the preheating component is less than or equal to the critical temperature for falling rate T1 and greater than or equal to the system ambient temperature T2, the heating component heats at full power and the heat storage power of the preheating component is 0.

[0087] S510, when the liquid temperature after preheating by the preheating component is lower than the system ambient temperature T2, the heating component heats at full power, and the heat storage power of the preheating component is 0.

[0088] In this embodiment, two schemes can be selected when determining the initial liquid volume. The first scheme involves first acquiring the temperature of the preheating component after receiving the heating command to determine its state, i.e., its preheating efficiency. Then, the initial flow rate is determined based on the actual preheating efficiency of the preheating component. In other words, the state of the preheating component is related to the initial flow rate, making the initial liquid volume more reasonable and avoiding situations where the initial liquid volume is too large, preventing the liquid from boiling, or too small, failing to meet the high flow rate requirement. The second scheme involves directly passing the liquid through the heating component at a set flow rate after receiving the heating command. That is, the initial liquid volume is the set flow rate, i.e., a preset high flow rate, for liquid heating. After heating begins, the temperature of the preheated liquid is detected by the preheating component, and then the actual flow rate is controlled based on the actual temperature range detected by the preheating component. This scheme does not consider the actual state of the preheating component when determining the initial liquid volume, making the determination of the initial liquid volume more convenient and the control logic simpler, thus making the product control method easier to implement.

[0089] Further, the step of determining the initial liquid volume passing through the heating component based on the temperature of the preheating component includes: when the temperature of the preheating component is greater than or equal to a second temperature value, controlling the liquid to pass through the heating component at a set flow rate; when the temperature of the preheating component is less than or equal to the second temperature value but greater than a first temperature value, controlling the liquid to pass through the heating component at a first flow rate, the first flow rate being greater than the set flow rate; and when the temperature of the preheating component is less than the first temperature value, controlling the liquid to pass through the heating component at a second flow rate, the second flow rate being less than the set flow rate.

[0090] In this embodiment, the initial liquid volume passing through the heating component can be determined by comparing the temperature of the preheating component with the first and second temperature values. When the temperature of the preheating component is greater than the second temperature value, it indicates that the preheating component is basically in a state of heat storage saturation, i.e., fully charged. Therefore, heating can be carried out at a set flow rate to achieve the preset large flow rate of water output. When the temperature of the preheating component is less than the first temperature value but greater than the second temperature value, the first flow rate (generally less than the set flow rate) is used as the initial liquid volume for output to ensure that the initial liquid volume is moderate, since there is still a certain preheating effect at this stage. When the temperature of the preheating component is less than the first temperature value, the second flow rate is used as the initial liquid volume for output. The second flow rate is basically equal to the conventional flow rate without a preheating component, generally around 6.5 g / s, which ensures that the liquid can be heated to the target output temperature, such as boiling.

[0091] Specifically, the second temperature value is the temperature at which the preheating component completes energy storage, that is, the temperature of the phase change material after the preheating component completes heat storage, and the second temperature value is greater than or equal to 80℃ and less than or equal to 100℃.

[0092] The initial temperature value is generally greater than or equal to 40℃ and less than or equal to 60℃. This value can be set according to actual conditions, but it should not be too high or too low. If it is too high, the preheating effect will be good, but the initial flow rate will be small, which does not meet the high flow rate requirement of this product. If it is too low, it will lead to insufficient preheating capacity, resulting in an excessive flow rate and failure to heat the water to boiling.

[0093] Example 3

[0094] Compared with the previous embodiments, this embodiment further includes a step of controlling the flow rate of the liquid through the heating component based on the temperature range of the preheated liquid. Specifically, the method, as follows: Figure 6 As shown, it includes the following steps:

[0095] S602, when the preheated liquid temperature is greater than or equal to the full-load charging temperature T3, the liquid is controlled to pass through the heating component at a first flow rate, and the first flow rate is greater than or equal to the set flow rate.

[0096] S604, when the preheated liquid temperature is less than the full-load charging temperature T3 and greater than or equal to the deceleration critical temperature T1, the liquid is controlled to pass through the heating component at a set flow rate.

[0097] S606, when the preheated liquid temperature is less than the critical temperature for slowing down T1 and greater than or equal to the system ambient temperature T2, the flow rate of the liquid through the heating component is less than or equal to the set flow rate and greater than the second flow rate.

[0098] S608, when the preheated liquid temperature is less than or equal to the system ambient temperature T2, the liquid is controlled to pass through the heating component at a second flow rate, which is less than the set flow rate.

[0099] In this embodiment, the preheated temperature is initially divided into four stages based on the full-load charging temperature T3, the critical rate-decreasing temperature T1, and the system ambient temperature T2. The flow rate decreases sequentially in each of these four stages. Specifically, in the temperature range above the full-load charging temperature T3, the flow rate is the first velocity, which is relatively high and can meet the requirements for large-flow-rate water output. In the range between the full-load charging temperature T3 and the critical rate-decreasing temperature T1, the flow rate is the set velocity, also belonging to the large-flow-rate water output stage. In the range between the critical rate-decreasing temperature T1 and the system ambient temperature T2, the flow rate is between the set velocity and the second velocity, and can be a fixed value or a value that dynamically changes with temperature. When the preheated temperature is below the system ambient temperature T2, the flow rate is the normal flow rate, i.e., the second velocity. This solution, during actual liquid dispensing, rationally controls the flow rate of the liquid through the heating element based on the temperature range of the liquid after preheating by the preheating component. In other words, it adjusts the flow rate according to the actual preheating state of the preheating component, avoiding both insufficient liquid temperature due to consistently high preheating flow and insufficient flow rate due to consistently low preheating flow. Through this adjustment, a high flow rate can be dispensed when the preheating effect is good, and the flow rate can be reduced in time when the preheating effect is poor to ensure the desired liquid temperature. This maximizes both the preset high flow rate and the required liquid temperature, thus achieving high flow rate control and improving the user experience.

[0100] Furthermore, when the preheated liquid temperature is less than the deceleration critical temperature T1 and greater than or equal to the system ambient temperature T2, and / or when the preheated liquid temperature is greater than or equal to the full-load charging temperature T3, the flow rate of the liquid through the heating component is positively correlated with the preheated liquid temperature.

[0101] In this embodiment, the liquid flow rate varies across different temperature ranges after preheating. Within each specific temperature range, the flow rate can be adjusted according to the temperature. For example, when the preheated liquid temperature falls within the range of the critical temperature T1 (decreasing rate threshold) to the system ambient temperature T2, the flow rate can be gradually reduced from a set flow rate to a second flow rate. For instance, a temperature-flow rate curve can be set for each temperature range, and the specific heating flow rate can be set according to the corresponding temperature. Furthermore, when the preheated liquid temperature is higher than the full-load charging temperature T3, the higher the temperature, the higher the flow rate. Generally, after the temperature exceeds the set temperature T4, heating is performed at a fixed flow rate value; that is, the first flow rate is also a variable value. Specifically, in the range where the preheated temperature exceeds the set temperature T4, the first flow rate is a first fixed value. In the range where the preheated temperature is lower than the set temperature T4 but higher than the full-load charging temperature T3, the first flow rate gradually decreases from the first fixed value to a second fixed value (generally the set flow rate value).

[0102] Furthermore, the flow rate is set to be greater than or equal to 9 g / s and less than or equal to 15 g / s. That is, the rated flow rate of the liquid passing through the heating component is 9 g / s-15 g / s.

[0103] Example 4

[0104] This embodiment also has the following differences:

[0105] The control method further includes: controlling the preheating component to store heat when the liquid handling system is in a non-heating state. Alternatively, if the liquid handling system includes a non-heating state, the control method further includes: in the non-heating state, controlling the preheating component to store heat at a first heat storage power, and after heat storage is completed, maintaining the temperature at a second heat storage power, wherein the first heat storage power is greater than the second heat storage power.

[0106] In these embodiments, the liquid handling system includes a non-heating state, i.e., an idle state when the user is not dispensing liquid. In this state, the preheating component heats at full power (first heat storage power) using its set maximum power to quickly accumulate heat. After accumulating enough heat, it can reduce its power to a second heat storage power for heat preservation. This ensures that the preheating component can remain in a state of full heat storage for an extended period, thereby ensuring that when the user needs liquids such as water, the preheating component can promptly preheat the liquid to the required temperature.

[0107] In any of the above embodiments, the control method further includes: in response to a preset time during startup, putting the liquid handling system into a prohibited heating state and causing the preheating component to perform full-power heat storage.

[0108] In these embodiments, when the liquid handling system is first turned on, the preheating components do not have enough time to store heat, so the system cannot meet the requirements for large-flow liquid discharge for a short period after startup. Therefore, a startup protection period is set, in which the liquid handling system is in a state of no-discharge (no-heating) for a short period after startup to allow the preheating components time to store heat. This preset time is reasonably set according to the time required for the preheating components to store heat to saturation. During this stage, the preheating components can be made to store heat at full power for rapid heat storage to quickly reach saturation.

[0109] In any of the above embodiments, the control method further includes: when a heating command is received, detecting the time interval since the last liquid dispensing; when the time interval is greater than or equal to a preset interval, controlling normal liquid dispensing; when the time interval is less than the preset interval, prohibiting liquid dispensing, or reducing the liquid dispensing rate and making the liquid temperature output by the heating component greater than the preset target temperature.

[0110] In these embodiments, when a heating command is received, if the interval since the last liquid dispensing is detected to be short, no comparison of preset temperature parameters is performed. Instead, the liquid dispensing is directly limited or the dispensing rate is reduced, ensuring that the liquid temperature output by the heating component is higher than the preset target temperature. This simplifies the overall control process of the product. After all, when the dispensing interval is short, the preheating component has not had time to recover its heat storage, generally failing to meet the set high-flow-rate dispensing requirement. Therefore, to improve control efficiency, temperature-related judgments are not performed; the dispensing is directly limited or the dispensing rate is reduced to ensure that the output liquid meets the target dispensing requirement. Here, the preset interval is greater than or equal to the time required for the preheating component to reach saturation from its lowest heat storage state. The lowest heat storage state refers to a state with virtually no preheating capacity.

[0111] In any of the above embodiments, the control method further includes: when a heating command is received, determining whether the preheating component is at the heat preservation power or whether the preheating component is in the heat storage saturation state; when the preheating component is at the heat preservation power or in the heat storage saturation state, controlling normal liquid discharge; when the preheating component is not at the heat preservation power or not in the heat storage saturation state, prohibiting liquid discharge or reducing the liquid discharge rate and making the liquid temperature output by the heating component greater than the preset target temperature.

[0112] In this embodiment, when a liquid dispensing command is detected, it is first determined whether the preheating component has completed heat storage. For example, if it is in a heat preservation state, heat storage is complete. Alternatively, the temperature of the preheating component can be directly detected to determine whether it has reached saturation. If so, it indicates that the preheating component has stored sufficient heat to meet the preset large flow rate liquid dispensing requirement. In this case, the normal procedure can be followed, first obtaining the preset temperature parameter and then adjusting the rate. Conversely, if the preheating component is not saturated, i.e., insufficient heat storage is detected, then when preparing to dispense liquid, the preset temperature parameter is not compared. Instead, the liquid dispensing rate is directly limited or reduced, and the liquid temperature output by the heating component is made higher than the preset target temperature. This simplifies the entire control process of the product. After all, when the preheating component does not store enough heat, the set large flow rate liquid dispensing requirement generally cannot be met. Therefore, to improve control efficiency, temperature-related judgments are not performed. For example, during long-term liquid dispensing or when the interval between consecutive liquid dispensing is short, temperature detection can be omitted, and the liquid dispensing rate can be directly limited or reduced to ensure that the output liquid meets the target liquid dispensing requirement.

[0113] In any of the above embodiments, the control method further includes: controlling the liquid supply volume at the liquid supply port to control the liquid discharge rate of the liquid processing system.

[0114] In these embodiments, the liquid handling system further includes a flow control device. The flow control device is disposed between the liquid supply port and the preheating component. A controller is connected to the flow control device and is used to adjust the liquid outflow rate by regulating the operation of the flow control device. When the liquid temperature in the liquid container and the temperature of the preheating component can be monitored by a second temperature detection device to reasonably control the outflow rate of the heating component, the liquid supply can be adjusted by controlling the flow rate of the flow control device, thereby regulating the amount of liquid entering the heating component, thus reasonably controlling the outflow rate.

[0115] In any of the above embodiments, the liquid handling system further includes a liquid collection box for collecting the liquid output from the heating component and a liquid discharge component for discharging the liquid collection box. The control method further includes: in response to a heating command, controlling the liquid discharge component to discharge liquid at a first liquid discharge rate; and after the liquid volume in the liquid collection box is less than a preset flow rate, controlling the liquid discharge component to discharge liquid at a second liquid discharge rate, wherein the second liquid discharge rate is less than the first liquid discharge rate.

[0116] In these embodiments, the liquid handling system also includes a collection box. A constant flow outlet valve is installed at the collection box to adjust the liquid flow rate and stabilize it at a preset rate. By using a collection box, water can be collected and discharged centrally, thus avoiding fluctuations in the liquid flow rate. That is, under normal circumstances, the heated liquid is collected in the collection box and discharged at a first discharge flow rate. Simultaneously, during the discharge process, the remaining liquid volume in the collection box can be monitored. If the volume is less than a set value, the discharge rate can be reduced to a second discharge flow rate to ensure continuous discharge. For example, if the system maintains a heating operation at the current conventional flow rate for an extended period, the liquid level in the collection box will gradually decrease. Once it decreases to a certain value, the discharge flow rate can be reduced to ensure continuous discharge.

[0117] like Figure 7 As shown, an embodiment of the second aspect of the present invention provides a control device for a liquid handling system, used for such... Figures 1 to 3 The liquid handling system shown includes a preheating component 2 and a heating component 3. The preheating component 2 stores heat and can use the stored heat to preheat the liquid passing through it. The heating component 3 is used to reheat the liquid preheated by the preheating component 2. The control device includes: an acquisition unit 902, used to acquire the temperature of the liquid after preheating by the preheating component during the liquid discharge process; and a control unit 904, used to control the heating power of the heating component and the heat storage power of the preheating component according to the temperature range of the preheated liquid.

[0118] Furthermore, the control unit 904 is also used in the steps of the control method for the liquid handling system provided in any embodiment of the first aspect.

[0119] The control device 900 for a liquid handling system provided by the present invention is a device corresponding to the control method for a liquid handling system provided in any embodiment of the first aspect. Therefore, the control device also has the effect corresponding to the control method for a liquid handling system provided in any embodiment of the second aspect, which will not be described again here.

[0120] like Figure 8 As shown, an embodiment of the third aspect of the present invention provides a control device 900 for a liquid handling system, including a memory 908 and a processor 906. The memory 908 stores programs or instructions that can be executed on the processor 906. When the programs or instructions are executed by the processor 906, they implement the steps of the control method for the liquid handling system provided in any embodiment of the first aspect.

[0121] An embodiment of the fourth aspect of the present invention provides a readable storage medium having a program or instructions stored thereon, which, when executed by a processor 906, implement the steps of the control method for the liquid handling system provided in any embodiment of the first aspect.

[0122] A fifth aspect of the present invention provides a liquid handling system, including a control device 900 for a liquid handling system provided in any of the foregoing embodiments, or a readable storage medium provided in any of the foregoing embodiments. Since the liquid handling system includes the control device 900 or the readable storage medium, it possesses all the beneficial effects of the control device 900 or the readable storage medium, which will not be elaborated further here.

[0123] Furthermore, such as Figure 1 and Figure 3 As shown, the liquid handling system includes a liquid supply port, connected to the preheating component 2, for supplying liquid to the entire system. The liquid supply port is located on the liquid container 1.

[0124] like Figure 1 and Figure 3 As shown, the liquid handling system also includes a controller 8, which controls the heating power of the heating component 3 and the heat storage power of the preheating component based on the detected temperature of the preheating component 2 and the temperature of the liquid container 1.

[0125] In any of the above embodiments, such as Figure 1 and Figure 2 As shown, the liquid handling system further includes: a first temperature detection device 7 for detecting the temperature of the preheating component 2; a second temperature detection device 6 for detecting the liquid temperature at the liquid supply port; a third temperature detection device for detecting the liquid temperature after preheating by the preheating component 2; and a fourth temperature detection device for detecting the system ambient temperature. Generally, the fourth temperature detection device is installed in the pipeline between the preheating component 2 and the heating component 3 to detect the pipe temperature when no liquid is being dispensed or when preparing to dispense liquid, as a reference for the system ambient temperature.

[0126] In any of the above embodiments, the liquid handling system further includes: a duration detection device for detecting the liquid discharge duration of the heating component 3 or the interval between the last liquid discharge of the heating component 3 and the last liquid discharge.

[0127] In this embodiment, the duration of each liquid dispensing cycle or the interval between two adjacent dispensing cycles can be detected using a duration detection device. This duration detection determines the single dispensing time, which affects the preheating capacity of the preheating component 2. Generally, as the dispensing time increases, its preheating capacity gradually decreases, and excessively short intervals also lead to a decrease in preheating capacity. Therefore, by monitoring the dispensing duration or the dispensing interval, the preheating capacity of the preheating component 2 can be predicted, thereby determining whether the current conditions can meet the set high-flow-rate dispensing. If not, the dispensing rate can be reduced. This design takes into account the impact of dispensing duration on the preheating of the preheating component 2, eliminating the possibility of insufficient dispensing temperature due to a decrease in the preheating capacity of the preheating component 2 caused by prolonged dispensing. This ensures that the liquid is heated to the required temperature while maintaining a high flow rate.

[0128] In any of the above embodiments, such as Figure 1 and Figure 3 As shown, the liquid handling system also includes a flow control device 4. The flow control device 4 is located between the liquid supply port and the preheating component 2. A controller is connected to the flow control device 4 and is used to adjust the liquid outflow rate by regulating the operation of the flow control device 4. When the liquid temperature of the liquid container 1 and the temperature of the preheating component 2 can be monitored by the second temperature detection device 6 to reasonably control the liquid outflow of the heating component 3, the amount of liquid entering the heating component 3 can be adjusted by controlling the flow of the flow control device 4, thereby reasonably controlling the liquid outflow.

[0129] Furthermore, the flow control device 4 can be a liquid pump. In addition to controlling the flow rate, the liquid pump can also increase the liquid supply pressure to avoid insufficient liquid supply due to insufficient hydraulic pressure.

[0130] In another embodiment, the flow control device 4 includes a flow regulating valve. That is, instead of a liquid pump, a flow regulating valve or the like can be used to regulate the amount of liquid passing through, thereby achieving control of the outflow rate.

[0131] In any of the above embodiments, such as Figure 2As shown, the preheating assembly 2 includes a heat exchange component. The heat exchange component includes a liquid pipeline 22. The liquid pipeline 22 is located between the liquid supply port and the heating assembly 3, connecting the two components. The liquid pipeline 22 is used to preheat the liquid supplied from the liquid supply port before supplying it to the heating assembly 3. Simultaneously, the preheating assembly 2 also includes a heat storage component 24, which has a certain heat storage capacity to store heat for later use. When liquid needs to be dispensed, the heat storage component 24 exchanges heat with the liquid in the liquid pipeline 22; that is, when liquid needs to be dispensed, the heat stored in the heat storage component 24 is transferred to the liquid in the liquid pipeline 22 to preheat the liquid. The preheating assembly 2 also includes a heating component 26. Heating component 26 is used to heat heat storage component 24 so that heat storage component 24 can continuously store heat. Heating component 26 can heat when no liquid is being discharged so that heat storage component 24 can store heat, or it can heat with a smaller power based on power distribution when heating so as to extend the preheating time of preheating component 2. This can increase the continuous liquid discharge time of the product so that the product can continuously supply boiling liquid for a longer time and at a larger flow rate.

[0132] In any of the above embodiments, such as Figure 2 As shown, the preheating component 2 includes an insulation component 28. The insulation component 28 surrounds the heat exchange component and is used to insulate the heat exchange component. By incorporating the insulation component 28, the insulation efficiency of the heat exchange component can be improved, preventing heat loss and thus reducing the power required to maintain its temperature, thereby lowering the product's energy consumption. Furthermore, due to the better insulation effect of the heat exchange component, it can be used for a longer period with the same heat storage capacity, thus increasing the continuous liquid dispensing time of the product.

[0133] In any of the above embodiments, the heating element 26 can be configured in different forms as needed, such as one or more combinations of a thick film, resistance wire, or ceramic heating element. Preferably, the heating element 26 is a resistance wire, as resistance wire is relatively common and thus reduces product cost. Furthermore, the heating element 26 is disposed inside the heat exchange component, meaning that the heating element 26 heats directly inside the heat exchange component. This avoids heat loss from the heating element 26 and improves its heating efficiency.

[0134] The preheating component 2 is a modular structure. It can be detachably installed between the liquid supply port and the heating component 3. In other words, the preheating component 2 is an optional component and can be configured as needed. It can be removed when preheating is not required, or it can be left unassembled during the outflow process.

[0135] In any of the above embodiments, a heat storage medium, such as a phase change material, is disposed within the heat storage component 24. The heating component 26 is specifically used to heat the heat storage medium so that the heat storage medium stores heat.

[0136] In any of the above embodiments, the heat storage medium includes one or more of heat transfer oil, water, or phase change materials.

[0137] In these embodiments, the type of heat storage medium can be set as needed, such as one or more of thermal oil, water, or phase change materials. Generally, phase change materials are chosen as the heat storage medium because they have better heat storage capacity and are easier to install and store. Of course, thermal oil and water can also be used as the heat storage medium. Alternatively, the heat storage medium can be a combination of multiple media, such as a combination of different phase change materials, or a combination of phase change materials with thermal oil or water.

[0138] In any of the above embodiments, such as Figure 2 As shown, the heat storage component 24 includes a phase change material 242 for heat storage, a liquid pipeline 22 is disposed inside the phase change material 242, a heating component 26 is located on one side of the phase change material 242 to heat the phase change material 242, and a first temperature detection device 7 is disposed on the other side of the phase change material 242 to detect the temperature of the phase change material 242. The temperature of the phase change material detected by the first temperature detection device 7 is the temperature of the preheating component 2. The heat storage capacity of the preheating component 2 can be determined by this temperature, and the flow rate of the product can be controlled in combination with this temperature.

[0139] In any of the above embodiments, the preheating component 2 ensures that the liquid dispensing rate is greater than or equal to 7.3 g / s. This means that the minimum liquid dispensing rate in this application is always greater than or equal to 7.3 g / s. In contrast, related technologies cannot achieve a liquid dispensing rate of 7.3 g / s for instant heating products, resulting in a slow dispensing rate and significantly reducing the user experience. In this application, the liquid dispensing rate is higher than that of similar products in related technologies, thereby improving the product's dispensing speed, enhancing the user experience, and ensuring a high flow rate.

[0140] In any of the above embodiments, the preheating component 2 will store heat in advance when not in a heating state, and then maintain the temperature after reaching saturation. Of course, if the interval between two liquid discharges of the product is short, the preheating component 2 may not have reached saturation before preheating is required. In general, the preheating component 2 will directly store heat when not in a heating state, and then maintain the temperature after saturation to prepare for subsequent preheating. In order to ensure heat storage efficiency, the preheating component 2 stores heat at full power when not in a heating state, that is, at the maximum power that the preheating component 2 can allow. At the same time, when in a heating state, if the heating component 3 heats at a non-full power, that is, if there is still a surplus according to the target power value P set by the safety regulations, the preheating component 2 can be controlled to store heat at the remaining power. That is, at this time, both the heating component 3 and the preheating component 2 are in a power consumption state, and the combined power consumption of the two is less than or equal to the value required by the safety regulations, such as the target power value P. In this configuration, since the preheating component 2 is also in a heating state during normal heating, the preheating component 2 can preheat the liquid while storing heat itself. This extends the preheating capacity of the preheating component 2, enabling it to continuously output liquid at the target temperature for a longer period of time, thereby achieving a large flow rate and long-term liquid output.

[0141] In any of the above embodiments, the liquid handling system further includes a liquid dispensing component 52. The liquid dispensing component 52 is connected to the heating component 3 and is used to dispense the liquid heated by the heating component 3. The liquid dispensing component 52 is the product's dispensing nozzle, through which the user can collect the liquid. Furthermore, the liquid dispensing component 52 and the heating component 3 can be directly connected or indirectly connected; that is, the liquid heated by the heating component 3 can be directly discharged through the liquid dispensing component 52, or it can be processed by a heat exchanger or other device before being discharged through the liquid dispensing component 52.

[0142] In any of the above embodiments, such as Figure 1 and Figure 3 As shown, the liquid handling system includes a liquid container 1. By setting up the liquid container 1, liquid can be stored in advance, eliminating the need for external water pipes and other structures, making the product placement more flexible and better suited to the requirements of desktop water dispensers, etc. Of course, the product can also omit the liquid container 1 (e.g., a water tank). In this case, the liquid handling system includes a connecting pipe that can connect to an external liquid source to transport the liquid from the external source to the preheating component 2.

[0143] Furthermore, the heating element 3 can be either an instantaneous heating element or a non-instantaneous heating element. An instantaneous heating element can quickly heat the liquid to boiling, achieving an instant hot and drinkable effect. A non-instantaneous heating element requires waiting for the liquid to boil before dispensing it; while it cannot achieve instant hot and drinkable results, it still ensures the dispensed liquid is at a suitable drinking temperature. In specific settings, the heating element 3 can be configured as either instantaneous or non-instantaneous, depending on the requirements. The instantaneous heating element 3 can be a thick-film heating element or a PTC element.

[0144] Furthermore, the liquid handling system is an instant heating container. Even further, the liquid handling system also includes a heat exchange device disposed between the liquid outlet assembly 52 and the heating assembly 3, used to cool the liquid heated to boiling by the heating assembly 3 to a temperature suitable for direct drinking, for the user to consume.

[0145] Furthermore, such as Figure 3 As shown, the liquid handling system includes a first branch and a second branch 9. The liquid supply port is connected to the heating component 3 via the first branch, which includes a preheating component 2. That is, the first branch is a preheating branch. The liquid supply port (located on the liquid container 1) is directly connected to the heating component 3 via the second branch 9, meaning the second branch 9 is a direct boiling branch. In this design, the system includes two branches, allowing the product to be preheated before output, thus achieving flow-controlled liquid discharge. Simultaneously, the product can also be discharged via the second branch 9 as a conventional product.

[0146] The control method provided in this application will now be described with reference to a more specific embodiment.

[0147] Specifically, this embodiment provides a working control method for a high-flow-rate instantaneous hot water dispensing system. Several parameters are pre-set in the system, including: preheating component equilibrium temperature T0 (T0 is the preheating component's charging protection temperature; charging ends upon reaching T0), rated charging power W1, high-flow-rate Vset, conventional instantaneous hot water machine flow rate V2, full-load charging temperature T3, system ambient temperature T2, and deceleration critical temperature T1. After the high-flow-rate instantaneous hot water dispensing system dispenses liquid, i.e., during the dispensing process, such as... Figure 9 As shown, it takes the following steps to control flow rate and power:

[0148] S902, obtain the liquid temperature T after preheating by the preheating component. When T≥T3, go to S904; when T3>T≥T1, go to S906; when T1>T>T2, go to S908; when T≤T2, go to S910.

[0149] S904, the liquid is allowed to pass through the heating component at a first flow rate to heat the liquid. The first flow rate is greater than the set flow rate Vset. At this time, the power allocated to the preheating component is greater than or equal to the rated charging power of the preheating component. The preheating component can be dynamically charged at full power, extending the working time of the preheating component.

[0150] Specifically, the rated charging power of the preheating module depends on the heat transfer efficiency between the heating element and the energy storage medium. If the charging power is too high, it may cause excessively rapid local temperature rise and uneven preheating module temperature, affecting module performance stability (for example, local temperatures exceeding 100℃ can cause water to boil directly when flowing through the preheating module, leading to pipe blockage or noise). If the rated charging power is too low, the charging time will be too long, affecting user experience. Generally, the designed rated charging power is between 400W and 800W.

[0151] Furthermore, at the full-load charging temperature T3, under the preset high flow rate, the back-end heating components heat to boiling point, while the remaining power can provide a balanced temperature for the preheating components to charge at full power.

[0152] S906: The liquid is heated at a set flow rate V, with the heating element's power being the first power. The heat storage element uses its remaining power to charge the preheating element. Specifically, when the dynamic outlet liquid temperature of the preheating element is between T3 and T1, liquid is discharged at a set high flow rate V (i.e., the set flow rate). At this time, the remaining power (total power - power of the downstream heating element) is less than the rated charging power of the preheating element. Therefore, the preheating element is charged using dynamic variable power to extend the system's operating time. During this time, some idle power is used to charge the preheating element, and the charging power is less than the rated charging power of the preheating element. T1 is the decreasing boiling point determination temperature. This temperature is reached when, at the preset high flow rate (i.e., when liquid is discharged at the set high flow rate V), the outlet liquid temperature of the heating element just meets the boiling point requirement when the downstream heating element heats at full power.

[0153] S908, with a reduced flow rate below the preset high-flow rate, but still higher than the flow rate of a traditional instant water heater, passes through the heating element at a second flow rate, causing the rear heating element to operate at full power. At this time, the heat storage element does not store heat.

[0154] In the S910 system, the liquid is heated at the flow rate of a traditional instant water heater, with the rear heating components operating at full power. During this time, the heat storage components do not store heat.

[0155] The above steps involve the flow rate regulation process after liquid discharge. At the initial moment of initiating liquid discharge, the initial velocity can be determined as follows:

[0156] S900 determines whether the instantaneous temperature of the preheating component of the high-flow instant hot water dispenser has reached (T1 + heat exchange threshold temperature ΔT). If it has, water is supplied according to the high-flow liquid output rate V. If it has not, the liquid is heated at the flow rate of a traditional instant hot water dispenser (i.e., the second flow rate), the rear heating component operates at full power, and the preheating component does not store heat. In other words, only the rear heating component is used for heating, and the liquid output flow rate is the same as a traditional instant hot water dispenser. After dispensing, the normal flow rate can be adjusted according to S902-S910. The heat exchange threshold temperature ΔT is the temperature difference between the preheating component and the system temperature when dispensing liquid according to the preheating component's setting V; generally, the preheating component's temperature is higher than the liquid output temperature, with ΔT between 2℃ and 6℃.

[0157] In another embodiment, at the initial moment of responding to the liquid discharge, its initial velocity can also be determined in the following way: water is supplied at a preset high flow rate V, the instantaneous temperature of the preheated liquid is judged to assess which heating step interval the system is in, and the system works in the heating step sequence.

[0158] T0 is typically between 80°C and 98°C, the phase change temperature of the energy storage medium. Excessively high temperatures can cause the water in the preheating component's piping to boil, affecting the liquid output from the branch and causing noise; conversely, excessively low preset temperatures will result in too low an outlet temperature after preheating, affecting the boiling flow rate.

[0159] The following is based on Figure 10 Taking the preheating temperature rise curve as an example, the control method of the system is further introduced. The system setting parameters are as follows: (1) the preheating component equilibrium temperature T0 = 86℃, ΔT = 5℃, and the rated charging power W1 = 600W; (2) the high flow rate V = 10g / s, and the flow rate of the conventional instant water heater V = 6.5g / s; (3) the full-load charging temperature T3 = 62℃; (4) the system ambient temperature T2 = 25℃; and (5) the deceleration critical temperature T1 = 48℃. The control method provided in this embodiment includes:

[0160] Initial flow rate determination step A0: Determine whether the preheating component of the high-flow instant hot water dispenser reaches 53℃; (1) If it reaches 53℃, supply water at a flow rate of 10g / s, determine which heating zone it is in based on the water temperature after preheating, and continue working according to the zone it is in; (2) If it does not reach 53℃, jump directly to step S4, and use only the post-heating component for heating. At this time, the liquid flow rate is the same as that of a traditional instant hot water dispenser.

[0161] Initial flow rate determination step A0: It can also be set to supply water at a preset high flow rate of 10g / s, and by judging the instantaneous temperature of the preheated liquid, assess which heating step range the system is in, and work according to the heating step sequence.

[0162] Liquid flow rate adjustment steps: During the liquid dispensing process, the temperature of the preheated liquid is obtained; the flow rate of the liquid through the heating element is controlled according to the temperature range of the preheated liquid. Specifically, this includes:

[0163] Stage A1: After preheating, the temperature is much higher than T3 (62℃). At this point, the power required for the downstream boiling is W2 = (100℃ - T3) × Cp × V, which is assumed to be ≤1600W, where Cp is the specific heat capacity of water. Therefore, the remaining power W = W0 - W2 ≥ 2300W - 1600W = 700W ≥ W1. Considering thermal efficiency and system safety, when T3 ≥ 62℃, the remaining power is higher than the rated charging power of the preheating component, allowing for full power charging of the preheating component and extending its operating time.

[0164] Furthermore, with a full-load charging temperature T3 = 62℃ and a high flow rate Vset = 10g / s, the power required for boiling at the downstream end is W2 = (100℃ - T3) × Cp × Vset ≤ 1600W. Therefore, the remaining power W = W0 - W2 ≥ 2300W - 1600W = 700W ≥ W1. Considering the electrothermal conversion efficiency and voltage fluctuations, when T3 ≥ 62℃, the remaining power is higher than the rated charging power of the preheating component, and the preheating component can be charged at full power, extending the component's working time. Therefore, when the liquid outlet flow rate Vset = 10g / s, the full-load charging temperature of the preheating component should not be lower than 62℃.

[0165] Stage A2: During the temperature range of T3-T1: After continuous energy consumption, the liquid outlet temperature of the preheating component gradually decreases (62℃~48℃). The remaining power is less than the rated charging power of the preheating component, so some of the power can be used to charge the preheating component and extend the working time of the component.

[0166] Furthermore, the critical temperature for slowing down is T1 = 48℃, which is the preset high flow rate V_set = 10g / s. The back-end heating component is heated at full power to meet the equilibrium temperature of boiling. The power required for the back-end heating is W2 = (100℃ - T1) × Cp × V2 = 52 × 4.2 × 10 = 2184W. The reason for this is that the limit power of the back-end heating does not exceed 2300W. Considering the electrothermal conversion efficiency and voltage fluctuation, the design limit of 2200W is reasonable. Therefore, under the condition of an overspeed liquid outflow rate V_set = 10g / s, the critical temperature for slowing down of the preheating component T1 should not be lower than 48℃.

[0167] Furthermore, when the preheated temperature T is between 62℃ and 48℃, the power required for the downstream boiling is W2 = (100℃ - T) × Cp × V. If W2 is between 1600W and 2200W, then the remaining power W is between 0W and 700W. Considering thermal efficiency and system safety, the remaining power is less than the rated charging power of the preheating component, so part of the power can be used to charge the preheating component and extend the component's working time.

[0168] Stage A3: When the preheated water temperature is lower than T1 (≤48℃) but higher than the ambient water temperature of the system, the flow rate is reduced to below 10g / s, but it can still be higher than the flow rate of 6.5g / s of traditional instant water heaters. At this time, the back-end heating components need to work at full power to boil the water, and there is no remaining power to charge the preheating components.

[0169] Stage A4: When the water temperature drops below T2 (25℃) after preheating, the flow rate gradually decreases to the traditional instant water heater flow rate of 6.5g / s, and the back-end heating components operate at full power.

[0170] The liquid handling system also includes a collection box 54, which is equipped with a constant flow outlet valve to adjust the liquid flow rate and stabilize it at a preset flow rate. If the system maintains the working state of stage A4 for a long period of time, after the liquid in the collection box 54 decreases to a certain value, the liquid flow rate will be adjusted to the normal flow rate to ensure continuous liquid output.
