Technical Field

The present application relates to a liquid processing system, a control method thereof, a control device thereof, and a readable storage medium.

Background

In daily life, people have the habit of drinking cool and white. The existing instant heating container can rapidly heat hot water. In daily life appliances, the highest power of the household desktop water dispenser is required to be limited within 2300W according to the safety requirements of the appliances. Theoretically, in a direct water dispenser scenario, this power can heat 7.3g/s room temperature water to boiling. However, the current water yield is low in electric heating efficiency and heat energy utilization rate, and the water yield of the direct water dispenser is generally lower than 6.5g/s, so that the water yield of the current desktop water dispenser and other products is low, and current interruption is easy to form, so that the use experience of a user is influenced.

Therefore, how to design a new liquid treatment system capable of discharging liquid at a large flow rate is a problem to be solved.

A fifth aspect of the present invention is to provide a storage medium for readable storage.

A sixth aspect of the invention is to provide a liquid treatment system.

The solution of the first aspect of the present invention provides a liquid treatment system, including: a liquid supply port; a preheating unit connected to the liquid supply port, capable of accumulating heat, and capable of preheating the liquid from the liquid supply port by the accumulated heat when the liquid treatment system is in a heating state; the heating component is connected with the preheating component and is used for reheating the liquid preheated by the preheating component; the first temperature detection device is used for detecting preset temperature parameters; and the controller is used for controlling the preheating component to store heat in a non-heating state and/or when the heating component heats at non-full power, judging whether the preset temperature parameter is smaller than a preset temperature threshold, and controlling the speed of liquid passing through the heating component and the heating power of the heating component when the preset temperature parameter is smaller than the preset temperature threshold so as to enable the heating component to output the liquid with the target temperature.

The liquid treatment system provided by the invention comprises a liquid supply port, a preheating component, a heating component, a first temperature detection device and a controller. The liquid treatment system can be a table-top water dispenser, and further a table-top direct-drinking water dispenser, namely a water dispenser which directly outputs liquid after being boiled or a water dispenser which outputs the liquid after being boiled and is adjusted to be suitable for temperature output after drinking. Specifically, the preheating unit is connected to the liquid supply port, and is intended to accumulate heat when the user is not using liquid such as water at ordinary times, that is, when the user is in an idle state, and then, when the user is using liquid such as water, the liquid supplied from the liquid supply port is preheated to a predetermined temperature by storing the accumulated energy in advance, and the preheated liquid is quickly heated to boiling by the heating unit. The liquid heated to boiling is discharged through the liquid outlet component, or the liquid heated to boiling can also exchange heat or be discharged after being combined with other liquids. The first temperature detecting device is used for detecting parameters such as the temperature of the preheating component, the temperature after the preheating component is preheated or the inlet and outlet temperature of the heating component, the inlet temperature of the preheating component and the like, and comparing the parameters with a preset temperature threshold value to judge whether the current state of the liquid treatment system can meet the preset flow (namely, the preset large flow) liquid outlet or not, for example, when the detected temperature is smaller than the preset temperature threshold value, the current state is indicated to not meet the preset large flow liquid outlet, and at the moment, the controller is required to adjust the heating power of the heating component or the speed of the liquid passing through the heating component so as to ensure that the temperature of the output liquid can meet the preset liquid outlet temperature requirement. Therefore, through the monitoring of parameters such as the temperature of the preheating component, the temperature after the preheating component is preheated or the inlet and outlet temperature of the heating component, the inlet temperature of the preheating component and the like, on one hand, the preset large-flow liquid outlet can be met maximally, on the other hand, the temperature of the output liquid can be ensured to meet the preset liquid outlet temperature requirement, and even if the temperature of the output liquid is higher than the target temperature, the large-flow liquid outlet control of the product is realized, and the use experience of a user is further improved.

In addition, this kind of scheme can store the accumulation heat in advance through preheating the subassembly in idle state to when liquid such as user's water is used, preheat the heat of accumulation through preheating the subassembly in advance and preheat liquid, and in preheating the stage, preheat the subassembly and preheat liquid, and need not consume the power, therefore, the total power that liquid processing system heated is the power of heating the subassembly, just so can realize higher efficient heating under lower power, so to the power of same heating the subassembly, it just can heat more liquid to boiling simultaneously, so can improve the speed that liquid processing system's liquid passes through heating the subassembly, the liquid outlet rate of domestic desktop water dispenser in the current scheme is low, easy problem of cutting off has been solved.

The preheating component stores heat in advance before liquid is discharged, which is different from the sectional heating, because each section is normally consumed in heating for the sectional heating. For example, although the front-stage heating device may be heated, the front-stage heating device does not accumulate heat in advance before discharging, but starts converting electric energy into heat when discharging. The essence of the staged heating is thus to divide a heating device into two heating sections, which still have the essence of heating simultaneously during tapping, rather than preheating the liquid during tapping. In general, a preheating assembly in this application is understood to mean a heat exchange device which, when it is intended to discharge liquid, exchanges heat stored in advance to the liquid delivered from the liquid supply port, so as to achieve preheating of the liquid.

In the above technical solution, when the preset temperature parameter is smaller than the preset temperature threshold, the controller controls the heating assembly to operate at full power, and controls the speed of the liquid passing through the heating assembly, so that the heating assembly outputs the liquid with the target temperature.

In the technical scheme, when the preset temperature parameter is smaller than the preset temperature threshold, the controller indicates that the current condition cannot meet the preset high-flow liquid outlet, at this time, in order to ensure the heating rate of the liquid passing through the heating component, the heating component can be directly controlled to operate at full power, namely the preheating component does not store heat, so that the liquid with relatively large flow can be heated to the required temperature, and the heating component passing rate of the liquid is improved as much as possible.

In any of the above solutions, the first temperature detecting device is configured to detect a temperature of the preheating component, and/or to detect a preheating temperature of the preheating component, and/or to detect an inlet temperature of the heating component, and/or to detect an inlet temperature of the preheating component. That is, the preset temperature parameter includes a temperature of the preheating component, a preheating temperature of the preheating component, an inlet temperature of the heating component, an inlet temperature of the preheating component, and the like. In the actual process, the one or more parameters may be set as preset temperature parameters according to the need.

For example, the preset temperature parameter may be specifically a temperature of the preheating component. The temperature of the preheating component is detected to know the heat accumulated in advance by the preheating component, and generally, when the preheating component reaches the preset temperature, the heat accumulation of the preheating component reaches the preset energy value, so that the preheating capacity of the preheating component can be determined by detecting the temperature, the liquid temperature after passing through the preheating component can be calculated according to the liquid temperature at the liquid supply port, and the liquid heated by the heating component can be ensured to reach the boiling state, so that high boiling liquid outlet is realized. On the contrary, if the temperature of the preheating component is lower than the preset temperature, the preheating component fails to be charged, the preheating efficiency is reduced, the liquid inlet flow rate can be moderately reduced according to the temperature of the liquid in the liquid container and the like, the preheating power of the preheating component is reduced, and the low-flow boiling liquid outlet is realized through the heating component.

In any of the above aspects, the liquid treatment system further comprises: the second temperature detection device is used for detecting the temperature of the liquid at the liquid supply port; and the controller is used for determining whether to control the speed of the liquid passing through the heating component based on the liquid temperature at the liquid supply port when the parameter detected by the first temperature detection device is smaller than a preset temperature threshold value, controlling the heating component to operate at full power when the liquid temperature at the liquid supply port is smaller than a liquid supply temperature set value, controlling the speed of the liquid passing through the heating component and enabling the heating component to output the liquid with the target temperature.

In this technical solution, the second temperature detecting device is configured to detect a temperature of the liquid at the liquid supply port, for example, for a product of the liquid processing system including the liquid container, the temperature of the liquid at the liquid supply port is a temperature of the liquid in the liquid container. The liquid temperature of the liquid in the liquid container and the like is monitored through the second temperature detection device, and the liquid flow of the heating assembly can be reasonably controlled through the monitoring of the temperature and other parameters of the preheating assembly through the first temperature detection device, so that the liquid flow is larger than the liquid flow provided by the single heating assembly while the liquid temperature is not lower than the target temperature. Meanwhile, the scheme also considers the influence of the liquid temperature at the liquid supply port, eliminates the liquid outlet temperature difference caused by the liquid temperature difference at the liquid supply port, thereby improving the liquid outlet control precision and ensuring the stability of the liquid outlet temperature.

In any of the above aspects, the liquid treatment system further comprises: and the duration detection device is used for detecting the liquid outlet duration of the heating assembly or the interval duration of the heating assembly from the last liquid outlet.

In this technical scheme, the duration of each liquid outlet or the duration of the liquid outlet interval between two adjacent liquid outlets can be detected according to the duration detection device, and the liquid outlet time can be determined by the duration detection, and the liquid outlet time can affect the preheating capacity of the preheating component, because generally, the preheating capacity of the preheating component can be gradually reduced along with the lengthening of the liquid outlet time, or the preheating capacity can be reduced due to the too short interval time. Therefore, the preheating capacity of the preheating component can be predicted by monitoring the liquid outlet time length or the liquid outlet interval time length, whether the current condition can meet the set large-flow liquid outlet or not can be predicted and judged, and if the current condition cannot meet the set large-flow liquid outlet, the speed of liquid passing through the heating component can be reduced. According to the arrangement, the preheating influence of the liquid outlet time on the preheating component is considered, the condition that the liquid outlet temperature is insufficient due to the fact that the preheating capacity of the preheating component is reduced due to long-time liquid outlet is eliminated, and therefore when the large-flow liquid outlet is ensured, the liquid can be heated to the required temperature.

In any of the above aspects, the liquid treatment system further comprises: the flow control device is arranged between the liquid supply port and the preheating component; the controller is configured to adjust the rate of liquid flow through the heating assembly by adjusting the operation of the flow control device.

In these aspects, the liquid handling system further comprises a flow control device. The flow control device is arranged between the liquid supply port and the preheating component. The controller is connected with the flow control device and is used for adjusting the speed of the liquid passing through the heating assembly by adjusting the operation of the flow control device. When the liquid outlet flow rate of the heating assembly is reasonably controlled through the monitoring of the liquid temperature of the liquid container and the monitoring of the temperature of the preheating assembly by the second temperature detection device, the liquid amount entering the heating assembly can be regulated through controlling the flow rate of the flow control device, so that the liquid outlet flow rate is reasonably controlled.

Further, the flow control device can be a liquid pump, and the liquid pump can control the flow, and can increase the liquid supply pressure, so that the liquid supply deficiency caused by the insufficient liquid pressure is avoided.

In another aspect, the flow control device includes a flow control valve, that is, a flow control valve or the like may be provided instead of the liquid pump to adjust the amount of liquid passing therethrough, so that the flow of the liquid can be controlled.

In any of the above technical solutions, the preheating assembly includes a heat exchange component, the heat exchange component includes: the liquid pipeline is connected between the liquid supply port and the heating component; and the heat storage component is used for exchanging heat with the liquid in the liquid pipeline. The preheating assembly further comprises a heating component for heating the heat storage component to store heat in the heat storage component.

In these embodiments, the preheating assembly includes a heat exchange member. The heat exchange component includes a liquid line. The liquid pipeline is arranged between the liquid supply port and the heating component, so that the connection between the liquid supply port and the heating component is realized. The liquid pipeline is used for preheating the liquid conveyed from the liquid supply port and conveying the preheated liquid to the heating assembly. Meanwhile, the preheating component further comprises a heat storage component, wherein the heat storage component has certain heat storage capacity and can store heat for subsequent use. When the liquid is needed to be discharged, the heat storage part exchanges heat with the liquid in the liquid pipeline, namely when the liquid is needed to be discharged, the heat stored in the heat storage part is transferred to the liquid in the liquid pipeline, so that the liquid is preheated. Meanwhile, the preheating assembly further comprises a heating component. The heating component is used for heating the heat storage component so that the heat storage component can continuously store heat, one heating component can heat when no liquid is discharged so that the heat storage component can store heat, and can heat with smaller power based on power distribution in a heating state so as to prolong the preheating time of the preheating component, thereby improving the continuous liquid discharging time of the product and enabling the product to continuously supply boiling liquid for a longer time and a large flow rate.

In any of the above solutions, the preheating assembly includes: and the heat preservation component is wrapped outside the heat exchange component and used for preserving heat of the heat exchange component.

In these embodiments, the preheating assembly includes a thermal insulation member. The heat preservation part wraps the heat exchange part, and the heat preservation part is used for preserving heat of the heat exchange part. The heat insulation efficiency of the heat exchange component can be improved through the arrangement of the heat insulation component, and the heat loss of the heat exchange component is avoided, so that the power required for maintaining the temperature of the heat exchange component can be reduced, and the energy consumption of a product is reduced. Meanwhile, the heat-preserving effect of the heat-exchanging component is good, so that the heat-exchanging component can be used for a longer time under the condition of the same heat-accumulating capacity, and the continuous liquid outlet time of the product can be prolonged.

In any of the above technical solutions, the heating component includes at least one of thick film, resistance wire, and ceramic heating plate.

In these embodiments, the heating elements may be configured differently and similarly as desired, and may be, for example, one or more of thick film, resistive wire, ceramic heater plate, etc. And most preferably, the heating component is a resistance wire, and the cost of the product can be reduced because the resistance wire is common. Further, the heating component is arranged inside the heat exchange component, namely, the heating component directly heats inside the heat exchange component, so that heat loss of the heating component can be avoided, and heating efficiency of the heating component is improved.

Wherein, preheat the subassembly and be modular structure. The preheating assembly can be detachably arranged between the liquid supply port and the heating assembly. That is, the preheating component is of a selected structure, and can be set according to the needs, and the preheating component can be disassembled when no preheating is needed, or the preheating component is not assembled when leaving the factory.

In any of the above aspects, a heat storage medium is provided in the heat storage member, and the heating member is configured to heat the heat storage medium.

In these embodiments, a heat storage medium, such as a phase change material, is disposed within the heat storage member. And the heating means is specifically for heating the heat storage medium so that the heat storage medium stores heat.

In any of the above embodiments, the thermal storage medium comprises one or more of thermal oil, water, or a phase change material.

In these embodiments, the type of thermal storage medium may be set as required, such as one or more of heat transfer oil, water, or phase change material. In general, the thermal storage medium is a phase change material because the phase change material has better thermal storage capacity and is better to install and store. Of course, it is also possible that the heat storage medium is provided as heat conducting oil, water. Or the thermal storage medium may be a combination of media such as a combination of different phase change materials, or a combination of phase change materials with thermally conductive oil or water.

In any one of the above technical solutions, the heat storage component includes a phase change material for storing heat, the liquid pipeline is disposed inside the phase change material, the heating component is located at one side of the phase change material to heat the phase change material, a third temperature detection device for detecting a temperature of the phase change material is disposed at the other side of the phase change material, and the temperature of the phase change material detected by the third temperature detection device is a temperature of the preheating component.

In these technical schemes, the heat storage component comprises a phase change material, the liquid pipeline is arranged inside the phase change material, the heating component is arranged on one side of the phase change material, and at this time, a third temperature detection device can be arranged on the other side of the phase change material to detect the temperature of the phase change material. The temperature is the temperature of the preheating component, and the heat storage capacity of the preheating component can be determined through the temperature, so that the temperature can be combined to control the flow of the product.

In any of the above technical solutions, the rate of liquid passing through the heating assembly of the liquid treatment system is 7.3g/s or more, or the rate of liquid passing through the heating assembly of the liquid treatment system is 9g/s or more and 13g/s or less.

In the technical scheme, the preheating component is used for preheating, so that the speed of liquid passing through the heating component can be more than or equal to 7.3g/s, namely, in the application, the minimum liquid outlet speed is more than or equal to 7.3 g/s. In the related art, the instant heating type product cannot achieve a liquid outlet rate of 7.3g/s, so that the liquid of the product passes through the heating component at a slower rate, and the experience of a user is seriously reduced. In the application, the speed of liquid passing through the heating component is higher than that of similar products in the related technology, so that the speed of the products is improved, the user experience is improved, and the products are ensured to realize large-flow liquid discharge.

In any of the above embodiments, the preheating component is configured to store heat at full power when in a non-heating state, and store heat when the heating component is heated at non-full power.

In the technical scheme, when the preheating component is in a non-heating state, heat can be stored in advance, and heat preservation is performed until the heat is stored to be saturated. Of course, if the product has a short discharge interval between two passes, the preheating assembly may begin to preheat without heat accumulation to saturation. However, in summary, the preheating assembly is directly subjected to heat accumulation until saturated as long as the preheating assembly is in a non-heating state, so that the preheating assembly is ready for subsequent preheating in advance. In order to ensure the heat storage efficiency, the preheating component stores heat at full power in the non-heating state, that is, at the maximum power allowable by the preheating component. Meanwhile, in the heating state, if the heating component heats with non-full power, that is, the target power value P set according to the safety regulations is remained, the preheating component can be controlled to store heat with the remained power, that is, at this time, the heating component and the preheating component are both in a power consumption state, and the power consumption of the two components together is less than or equal to the value required by the safety regulations, for example, the target power value P. In the arrangement, the preheating component is also in a heating state in a normal heating state, so that the preheating component can preheat liquid and store heat, the preheating capacity of the preheating component can be prolonged, and the liquid with target temperature can be continuously output for a longer time, so that the liquid with large flow and long time is discharged.

In any of the above technical solutions, the liquid treatment system further includes a liquid outlet component connected to the heating component, and configured to output the liquid heated by the heating component.

In these embodiments, the liquid treatment system further comprises a liquid outlet assembly. The liquid outlet component is connected with the heating component and is used for outputting the liquid heated by the heating component. The liquid outlet component is a liquid outlet nozzle of the product, and when the liquid outlet component is used by a user, liquid can be received through the liquid outlet component. Further, the liquid outlet component and the heating component can be directly connected or indirectly connected, namely, the liquid heated by the heating component can be directly discharged through the liquid outlet component, or can be discharged through the liquid outlet component after being treated by a heat exchange device and other devices.

In any of the above aspects, the liquid treatment system comprises a liquid container. The liquid container is arranged to store liquid in advance, so that structures such as an external water pipe are not needed, the placing position of the product is more flexible, and the requirements of a desktop water dispenser and the like are met. Of course, the product may not have a liquid container (e.g., a water tank), and the liquid treatment system may include a connecting tube that may be connected to an external source of liquid to deliver the liquid from the external source to the preheating assembly.

Further, the heating component can be an instant heating component or a non-instant heating component, and the instant heating component can rapidly heat liquid to boiling so as to achieve the effect of instant heating and instant drinking. Instead of the instant heating type assembly, the liquid can be output after the instant heating type assembly is heated to boiling, and the instant heating type assembly can not be used for instant drinking, but the output liquid temperature can be suitable for people to drink. In particular arrangements, the heating assembly may be configured to be instant heating, or not instant heating, as desired. Wherein, the instant heating component can be a thick mode heating tube or a PTC tube.

Further, the liquid treatment system is an instant heating vessel. Still further, the liquid treatment system further comprises a heat exchange device arranged between the liquid outlet assembly and the heating assembly for cooling the liquid heated to boiling by the heating assembly to a temperature convenient for direct drinking for users to drink.

The technical scheme of the second aspect of the invention provides a control method of a liquid treatment system, which is used for the liquid treatment system provided by the technical scheme of the first aspect. The control method comprises the following steps: acquiring preset temperature parameters detected by a first temperature detection device; and a rate adjusting step: judging whether the preset temperature parameter is smaller than a preset temperature threshold, and controlling the heating assembly to operate at full power when the preset temperature parameter is smaller than the preset temperature threshold, controlling the speed of liquid passing through the heating assembly and enabling the heating assembly to output liquid with target temperature; wherein the preset temperature parameter comprises at least one of the following: the temperature of the preheating component, the preheating temperature of the preheating component, the inlet temperature of the heating component, the inlet temperature of the preheating component.

The liquid treatment system provided by the invention comprises a liquid supply port, a preheating component, a heating component, a first temperature detection device and a controller. The liquid treatment system can be a table-top water dispenser, and further a table-top direct-drinking water dispenser, namely a water dispenser which directly outputs liquid after being boiled or a water dispenser which outputs the liquid after being boiled and is adjusted to be suitable for temperature output after drinking. Specifically, the preheating unit is connected to the liquid supply port, and is intended to accumulate heat when the user is not using liquid such as water at ordinary times, that is, when the user is in an idle state, and then, when the user is using liquid such as water, the liquid supplied from the liquid supply port is preheated to a predetermined temperature by storing the accumulated energy in advance, and the preheated liquid is quickly heated to boiling by the heating unit. The liquid heated to boiling is discharged through the liquid outlet component, or the liquid heated to boiling can also exchange heat or be discharged after being combined with other liquids. The first temperature detecting device is used for detecting parameters such as the temperature of the preheating component, the temperature after the preheating component is preheated or the inlet and outlet temperature of the heating component, the inlet temperature of the preheating component and the like, and comparing the parameters with a preset temperature threshold value to judge whether the current state of the liquid treatment system can meet the preset flow (namely, the preset large flow) liquid outlet or not, for example, when the detected temperature is smaller than the preset temperature threshold value, the current state is indicated to not meet the preset large flow liquid outlet, and at the moment, the controller is required to adjust the heating power of the heating component or the speed of the liquid passing through the heating component so as to ensure that the temperature of the output liquid can meet the preset liquid outlet temperature requirement. Therefore, through the monitoring of parameters such as the temperature of the preheating component, the temperature after the preheating component is preheated or the inlet and outlet temperature of the heating component, the inlet temperature of the preheating component, on one hand, the preset large-flow liquid outlet can be met maximally, on the other hand, the temperature of the output liquid can be ensured to meet the preset liquid outlet temperature requirement, so that the large-flow liquid outlet control of the product is realized, and the use experience of a user is further improved.

In addition, this kind of scheme can store the accumulation heat in advance through preheating the subassembly in idle state to when liquid such as user's water is used, preheat the heat of accumulation through preheating the subassembly in advance and preheat liquid, and in preheating the stage, preheat the subassembly and preheat liquid, and need not consume the power, therefore, the total power that liquid processing system heated is the power of heating the subassembly, just so can realize higher efficient heating under lower power, so to the power of same heating the subassembly, it just can heat more liquid to boiling simultaneously, so can improve the speed that liquid processing system's liquid passes through heating the subassembly, the liquid outlet rate of domestic desktop water dispenser in the current scheme is low, easy problem of cutting off has been solved. For example, for a household desktop water dispenser, the highest heating power is required to be limited to 2300W according to the electrical safety requirements, that is, the heating power of the heating component is required to be less than or equal to 2300W. Under the power, the liquid outlet flow of the liquid treatment system such as a direct water dispenser is usually less than 6.5g/s due to the loss of the electric heating efficiency and the heat energy utilization rate, so that the liquid outlet flow of the existing products such as a desktop water dispenser is small, and the phenomenon of flow interruption is easy to form. In this application, when setting up heating element's heating power at 2300W, because the liquid before its heating is preheated through preheating the subassembly, so its play liquid flow is obviously greater than current 6.5g/s to this play liquid flow that just has improved the product, it is little to have solved the play liquid flow of products such as desktop water dispenser among the current scheme, problem of easy cutout.

In any of the above solutions, the rate adjustment step includes: acquiring the liquid temperature at the liquid supply port; when the preset temperature parameter is smaller than the preset temperature threshold value, whether to control the speed of liquid passing through the heating component is determined based on the liquid temperature at the liquid supply port, and when the liquid temperature at the liquid supply port is smaller than the liquid supply temperature set value, the heating component is controlled to operate at full power, the speed of liquid passing through the heating component is controlled, and the heating component outputs the liquid with the target temperature. Further, when the liquid temperature at the liquid supply port is greater than or equal to the liquid supply temperature set value, the liquid flow is kept unchanged or increased, and the heating component outputs the liquid with the target temperature.

In these embodiments, the liquid processing system further includes a second temperature detecting device, configured to detect a temperature of the liquid at the liquid supply port, for example, for a product in which the liquid processing system includes a liquid container, the temperature of the liquid at the liquid supply port is a temperature of the liquid in the liquid container. And when the speed is specifically regulated, firstly acquiring the liquid temperature at the liquid supply port, if the preset temperature parameter is smaller than the preset temperature threshold value, indicating that the preset large-flow liquid outlet can not be realized, at this time, if the liquid temperature at the liquid supply port is also lower, controlling the heating assembly to perform full-power heating, then determining the allowable maximum liquid passing speed of the heating assembly according to the actual situation, and carrying out liquid outlet at the allowable maximum liquid passing speed of the heating assembly. However, if the liquid temperature at the liquid supply port is greater than the set value, it is indicated that the liquid temperature at the liquid supply port is higher, so that the liquid outlet flow rate can be kept unchanged or increased according to the actual situation, and the heating assembly can output the liquid with the target temperature. The liquid supply temperature set value can be reasonably set according to actual conditions and by combining preset parameters such as large flow and the like. According to the scheme, the liquid temperature of the liquid in the liquid container and the like is monitored through the second temperature detection device, and the liquid outlet flow of the heating assembly can be reasonably controlled through the monitoring of the temperature and other parameters of the preheating assembly through the first temperature detection device, so that the liquid outlet flow is larger than the liquid outlet flow provided by the single heating assembly while the liquid outlet temperature is not lower than the target temperature. Meanwhile, the scheme also considers the influence of the liquid temperature at the liquid supply port, eliminates the liquid outlet temperature difference caused by the liquid temperature difference at the liquid supply port, thereby improving the liquid outlet control precision and ensuring the stability of the liquid outlet temperature.

In any of the above solutions, the preset temperature parameter includes a temperature of the preheating component and an inlet temperature of the preheating component, and the rate adjusting step includes: when the inlet temperature of the preheating component is less than or equal to a first preset temperature threshold value, controlling the heating component to operate at full power, controlling the speed of liquid passing through the heating component and enabling the heating component to output liquid with target temperature; determining whether to control the rate of liquid passing through the heating assembly based on the temperature of the preheating assembly when the inlet temperature of the preheating assembly is greater than a first preset temperature threshold; when the temperature of the preheating component is determined to be smaller than the temperature set value of the preheating component, controlling the heating component to operate at full power, controlling the speed of liquid passing through the heating component and enabling the heating component to output liquid with target temperature; when the temperature of the preheating component is greater than or equal to the preset value of the temperature of the preheating component, the liquid outlet flow is kept unchanged or increased, and the heating component outputs the liquid with the target temperature.

In the technical schemes, when the inlet temperature of the preheating component is smaller than or equal to a first preset temperature threshold value, the heating component is controlled to operate at full power, the speed of liquid passing through the heating component is reasonably controlled, and the output liquid is ensured to meet the requirement of liquid outlet. If the inlet temperature of the preheating assembly is greater, i.e., greater than a first preset temperature threshold, then it is further determined whether a rate adjustment is to be made in conjunction with the temperature of the preheating assembly itself. For example, when the temperature of the preheating component is smaller than the preset value of the preheating component, the heat storage capacity is insufficient, so that the heating component is controlled to operate at full power, and when the temperature of the preheating component is larger than or equal to the preset value of the preheating component, that is, the heat storage capacity is sufficient, the flow can be locally increased or the flow can be kept unchanged. In any case, however, it is ensured that the output liquid meets the liquid output requirement. This approach combines the inlet temperature of the preheating assembly with the temperature of the preheating assembly itself to achieve a reasonable adjustment of the rate. Therefore, the liquid outlet flow rate is larger than that provided by the single heating component while the liquid outlet temperature is not lower than the target temperature. Meanwhile, according to the scheme, the inlet temperature of the preheating component is considered, the liquid outlet temperature difference caused by the liquid temperature difference at the liquid supply port is eliminated, so that the liquid outlet control precision is improved, and the stability of the liquid outlet temperature is ensured.

In any of the above aspects, the step of controlling the heating assembly to operate at full power, controlling the rate at which the liquid passes through the heating assembly, and causing the heating assembly to output the liquid at the target temperature comprises: judging whether the heating assembly can output liquid with target temperature or not when the heating assembly runs at full power; when the heating assembly is operated at full power and the heating assembly is unable to output the liquid at the target temperature, the liquid outlet flow rate is reduced.

In these technical solutions, when the heat storage capacity is insufficient, the full-power operation of the heating assembly is generally controlled, at this time, it is first determined whether the heating assembly can output the liquid at the target temperature when the heating assembly is in full-power operation, if so, the full-power operation is performed, or the power is properly reduced, or the rate is properly increased, and if not, the rate of the liquid passing through the heating assembly needs to be reduced. That is, the scheme always takes the high-flow liquid outlet as a priority condition, and gradually reduces the speed when the preset high-flow liquid outlet cannot be met, so that the liquid outlet is ensured to meet the temperature requirement.

In any of the above aspects, the liquid treatment system includes a heating state, and the control method includes: and in the heating state, under the condition that the heating power of the heating component is smaller than or equal to the target power value, calculating the power difference value between the target power value and the heating power of the heating component, and controlling the preheating component to store heat according to the power difference value.

In these embodiments, the liquid handling system includes a heated state, such as a user-connected state. In the heating state, the heating power W2 of the heating element may be calculated first, and then the relation between the heating power W2 and the target power value P may be determined. If the value of the heating power W2 is smaller than or equal to the target power value P, the heating component is controlled to heat at the calculated power W2, and meanwhile, the preheating component is controlled to store heat at the power W1 of P-W2. The target power value P is generally set according to the electrical specifications of the electric appliance, such as 2300W. According to the scheme, the heating power W2 required by the heating component for heating the liquid to the current liquid outlet temperature is calculated, so that whether the current power consumption of the product is relatively maximum or not can be judged, namely whether the target power value P is remained or not, if so, the heating component can be controlled to store heat by the remained power, namely, at the moment, the heating component and the heating component are in a power consumption state, and the power consumption of the heating component and the heating component together is smaller than or equal to a value required by safety regulations, such as the target power value P. In the arrangement, the preheating component is also in a heating state in a normal heating state, so that the preheating component can preheat liquid and store heat, the preheating capacity of the preheating component can be prolonged, and the liquid with target temperature can be continuously output for a longer time, so that the liquid with large flow and long time is discharged.

In any of the above solutions, the liquid treatment system includes a non-heating state, and the control method further includes: the preheating component is controlled to store heat when the liquid treatment system is in a non-heating state. Further, the control method includes: and in a non-heating state, controlling the preheating component to store heat at a first heat storage power, and preserving heat at a second heat storage power after the heat storage is completed, wherein the first heat storage power is larger than the second heat storage power.

In these embodiments, the fluid handling system includes a non-heated state, i.e., an idle state when the user is not receiving fluid. In this state, the preheating module performs full-power (first regenerative power) heating at its own set maximum power so as to be able to rapidly accumulate full heat. And after full heat is accumulated, the power can be reduced (second heat storage power) to perform heat preservation. Therefore, the preheating component can be ensured to be in a state of storing full heat for a long time, and the preheating component can be ensured to preheat liquid to a required temperature in time when a user needs the liquid such as water.

In any of the above technical solutions, the control method further includes: and in response to the preset time of starting, the liquid treatment system is in a heating limiting state, and the preheating component is subjected to full-power heat accumulation.

In the technical schemes, when the liquid treatment system is just started, the preheating component is not used for heat storage, so that the requirement of large-flow liquid outlet can not be basically met in a period of just starting, and a starting protection period is set, namely, the liquid treatment system is in a limited heating state in a period of just starting, so that the preheating component can store heat for a long time conveniently. The preset time is reasonably set according to the time from heat accumulation to saturation required by the preheating component. At this stage, the preheating assembly can be rapidly stored at full power so as to be capable of rapidly storing heat to a saturated state.

In any of the above technical solutions, before the step of obtaining the preset temperature parameter and performing the rate adjustment, the method further includes: when a liquid outlet instruction is obtained, detecting a time interval from the last liquid outlet; when the time interval is greater than or equal to the preset interval, executing the step of acquiring preset temperature parameters and performing rate adjustment; when the time interval is less than the preset interval, the liquid outlet is limited, or the speed of the liquid passing through the heating component is reduced, and the heating component outputs the liquid with the target temperature.

In these technical schemes, when the liquid outlet instruction is obtained, if the interval between the liquid outlet instruction and the last liquid outlet is detected to be shorter, the comparison judgment of the preset temperature parameter is not performed, the liquid outlet is directly limited or the speed of the liquid passing through the heating component is reduced, and the liquid with the target temperature is output by the heating component, so that the whole control flow of the product can be simplified. Wherein, here preset interval is greater than or equal to the time that preheating assembly required to heat accumulation from heat accumulation minimum state to saturation, and heat accumulation minimum state is the state that does not basically have the preheating capacity.

In any of the above technical solutions, the control method further includes: when a liquid outlet instruction is obtained, judging whether the preheating component is in heat preservation power or judging whether the preheating component is in a heat storage saturation state; when the preheating component is in heat preservation power or in heat storage saturation state, executing the step of acquiring preset temperature parameters and performing rate adjustment; when the preheating component is not in heat preservation power or in heat storage saturation state, limiting liquid outlet or reducing the speed of liquid passing through the heating component and enabling the heating component to output liquid with target temperature.

In the technical scheme, when the command of liquid discharge is detected, whether the preheating component stores heat is judged, for example, whether the preheating component is in a heat preservation state or not is judged, for example, whether the heat storage is finished is judged, or whether the temperature of the preheating component is stored to be saturated is judged by directly detecting the temperature of the preheating component. If yes, the preheating component stores more heat, and can meet the requirement of preset large-flow liquid outlet, at the moment, preset temperature parameters can be acquired first according to a normal flow, and the speed regulation is performed. On the contrary, the preheating component is not saturated in heat accumulation, namely, the insufficient heat accumulation of the preheating component is found, when the liquid is prepared, the comparison judgment of preset temperature parameters is not carried out, the liquid is directly limited to be discharged or the speed of the liquid passing through the heating component is reduced, and the heating component outputs the liquid with the target temperature, so that the whole control flow of the product can be simplified, after all, when the insufficient heat accumulation of the preheating component is carried out, the liquid discharging requirement with large flow rate is generally not met, and therefore, in order to improve the control efficiency, the temperature-related judgment is not carried out, for example, when the liquid is discharged for a long time, or when the continuous liquid discharging interval is shorter, the judgment of temperature detection is not carried out, the liquid is directly limited to be discharged or the speed of the liquid passing through the heating component is reduced, so that the output liquid can meet the target liquid discharging requirement.

In any of the above technical solutions, the control method further includes: the liquid supply amount of the liquid supply port is controlled to control the rate of liquid passing through the heating assembly of the liquid processing system.

In these aspects, the liquid handling system further comprises a flow control device. The flow control device is arranged between the liquid supply port and the preheating component. The controller is connected with the flow control device and is used for adjusting the speed of the liquid passing through the heating assembly by adjusting the operation of the flow control device. When the liquid temperature of the liquid in the liquid container is monitored through the second temperature detection device and the liquid flow rate of the heating assembly is reasonably controlled through the monitoring of the temperature of the preheating assembly, the liquid supply amount can be regulated through controlling the flow rate of the flow control device, so that the liquid flow rate can be reasonably controlled by regulating the liquid amount entering the heating assembly.

A third aspect of the present invention provides a control device for a liquid treatment system, for use in the liquid treatment system provided in any one of the first aspect, the control device comprising: the acquisition unit is used for acquiring the preset temperature parameter detected by the first temperature detection device; the control unit is used for judging whether the preset temperature parameter is smaller than a preset temperature threshold value, and controlling the heating assembly to run at full power when the preset temperature parameter is smaller than the preset temperature threshold value, controlling the speed of liquid passing through the heating assembly and enabling the heating assembly to output liquid with target temperature; wherein the preset temperature parameter comprises at least one of the following: the temperature of the preheating component, the preheating temperature of the preheating component, the inlet temperature of the heating component, the inlet temperature of the preheating component.

Further, the control device is also used for the steps of the control method of the liquid treatment system provided in any one of the second aspects.

According to the control device of the liquid treatment system provided by the invention, since the control device is a device corresponding to the control method of the liquid treatment system provided by any one of the first aspect, the control device also has the effect corresponding to the control method of the liquid treatment system provided by any one of the second aspect, and will not be described in detail.

Detailed Description

In order that the above-recited aspects, features and advantages of embodiments according to the present invention can be more clearly understood, a further detailed description of embodiments according to the present invention will be rendered by reference to the appended drawings and detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of embodiments according to the invention, however, embodiments according to the invention may be practiced otherwise than as described herein, and thus the scope of protection according to embodiments of the invention is not limited by the specific embodiments disclosed below.

The liquid treatment system provided herein is described below with reference to fig. 1.

Example 1

As shown in fig. 1, the embodiment of the first aspect of the present invention provides a liquid treatment system, which includes a liquid supply port (such as an outlet of a liquid container 1), a preheating assembly 2, a heating assembly 3, a second temperature detecting device 6, a first temperature detecting device 7, and a controller 8. The preheating component 2 is connected with the liquid supply port, can store heat, and can preheat the liquid conveyed by the liquid supply port by utilizing the heat storage when the liquid treatment system is in a heating state. The heating component 3 is connected with the preheating component 2 and is used for reheating the liquid preheated by the preheating component 2. The first temperature detecting means 7 is for detecting a preset temperature parameter. The controller 8 is configured to control the preheating component 2 to store heat in a non-heating state and/or when the heating component 3 is heated with non-full power, and the controller 8 is further configured to determine whether a preset temperature parameter is less than a preset temperature threshold, and when the preset temperature parameter is less than the preset temperature threshold, control a rate at which the liquid passes through the heating component and a heating power of the heating component 3, so that the heating component 3 outputs the liquid with the target temperature.

The liquid treatment system provided according to the present invention comprises a liquid supply port (typically the outlet of the liquid container 1), a preheating assembly 2, a heating assembly 3, a first temperature detecting device 7 and a controller 8. The liquid treatment system can be a table-top water dispenser, and further a table-top direct-drinking water dispenser, namely a water dispenser which directly outputs liquid after being boiled or a water dispenser which outputs the liquid after being boiled and is adjusted to be suitable for temperature output after drinking. Specifically, the preheating unit 2 is connected to the liquid supply port, and is intended to store heat when the user is not using liquid such as water at ordinary times, that is, when the user is not in a heating state at idle, and then, when the user needs liquid such as water, the liquid supplied from the liquid supply port is preheated to a predetermined temperature by storing the stored energy in advance, and the preheated liquid is quickly heated to boiling by the heating unit 3. The liquid heated to boiling is discharged through the liquid outlet component 5, or the liquid heated to boiling can be subjected to heat exchange or be discharged after being combined with other liquids. The first temperature detecting device 7 is configured to detect parameters such as a temperature of the preheating component 2, a temperature of the preheating component 2 after preheating, or an inlet and outlet temperature of the heating component 3, and an inlet temperature of the preheating component 2, and compare the parameters with a preset temperature threshold to determine whether the current state of the liquid processing system can meet a preset flow (i.e. a preset large flow) of liquid, for example, when the detected temperature is less than the preset temperature threshold, it is indicated that the current state cannot meet the preset large flow of liquid, and at the moment, the controller 8 is required to adjust the heating power of the heating component 3 or the speed of the liquid passing through the heating component so as to ensure that the temperature of the output liquid can meet the preset liquid outlet temperature requirement. Therefore, through the monitoring of parameters such as the temperature of the preheating component 2, the temperature after the preheating component 2 is preheated or the inlet and outlet temperature of the heating component 3, the inlet temperature of the preheating component 2 and the like, on one hand, the preset large-flow liquid outlet can be met maximally, and on the other hand, the temperature of the output liquid can be ensured to meet the preset liquid outlet temperature requirement, so that the large-flow liquid outlet control of the product is realized, and the use experience of a user is further improved.

In addition, this kind of scheme can store the accumulation heat in advance through preheating component 2 in idle state to when liquid such as user's water is used, preheat the liquid through preheating component 2 stores the accumulated heat in advance, and preheat the liquid in preheating stage, therefore, the total power that liquid processing system heated is the power of heating component 3, so can realize higher efficient heating under lower power, so for the power of same heating component 3, it just can heat more liquid to boiling simultaneously, so can improve the speed that liquid processing system's liquid passes through heating component, the play liquid speed of domestic desktop water dispenser in the current scheme is low, easy problem of cutting off flow has been solved. For example, for a household desktop water dispenser, the highest heating power is required to be limited to 2300W according to the electrical safety requirements, that is, the heating power of the heating component 3 is required to be less than or equal to 2300W. Under the power, the liquid outlet flow of the liquid treatment system such as a direct water dispenser is usually less than 6.5g/s due to the loss of the electric heating efficiency and the heat energy utilization rate, so that the liquid outlet flow of the existing products such as a desktop water dispenser is small, and the phenomenon of flow interruption is easy to form. In this application, when setting up heating power at 2300W with heating element 3, because the liquid before its heating is preheated through preheating element 2, so its play liquid flow is obviously greater than current 6.5g/s to this play liquid flow that just has improved the product, has solved the play liquid flow of products such as desktop water dispenser in the current scheme and is little, problem of easy cutout.

Here, the preheating module 2 stores heat in advance before discharging, which is different from the sectional heating, because each section is normally consumed during the heating for the sectional heating. For example, although the front-stage heating device may be heated, the front-stage heating device does not accumulate heat in advance before discharging, but starts converting electric energy into heat when discharging. The essence of the staged heating is thus to divide a heating device into two heating sections, which still have the essence of heating simultaneously during tapping, rather than preheating the liquid during tapping. In general, the preheating assembly 2 in the present application can be understood as a heat exchange device, which is intended to exchange heat stored in advance to the liquid delivered from the liquid supply port when the liquid is discharged, so as to achieve preheating of the liquid.

In this application, the liquid treatment system is in a heating state and a non-heating state, and is defined by whether the heating component 3 and the preheating component 2 are out of liquid or whether the liquid supply port is supplied with liquid. I.e. heated or unheated, is mainly to see if there is liquid to be heated to boiling.

Further, in the practical process, in order to make the user have a good experience, a flow regulator, such as a container of a liquid storage body, is arranged at the liquid outlet of the liquid treatment system, and the liquid with flow regulation is stored in the container, that is, the liquid is concentrated and output to the user after reaching a certain amount, so that the rate of the liquid passing through the heating component is uniform from the perspective of the user regardless of the flow of the liquid heated to boil, but not the liquid with a larger flow and a smaller flow is discharged, that is, the rate of the liquid is basically uniform when the user receives the liquid in the variable flow heating process can be ensured.

In this application, the rate at which liquid passes through the heating assembly is a first rate that is consistent with the rate at which liquid passes through the preheating assembly, or the rate at which liquid is supplied from the liquid supply port, rather than the rate at which liquid is directly output to the user (second rate).

In the above embodiment, the controller 8 controls the heating assembly 3 to operate at full power when the preset temperature parameter is less than the preset temperature threshold, and controls the rate at which the liquid of the heating assembly 3 passes through the heating assembly so that the heating assembly 3 outputs the liquid of the target temperature.

In this embodiment, when the preset temperature parameter is smaller than the preset temperature threshold, the controller 8 indicates that the current condition cannot meet the preset high-flow liquid, and at this time, in order to ensure the rate of liquid passing through the heating assembly, the heating assembly 3 can be directly controlled to operate at full power, that is, the preheating assembly 2 does not store heat, so as to be capable of heating the relatively large-flow liquid to the required temperature, so that the rate of liquid passing through the heating assembly is increased as much as possible.

In any of the above embodiments, as shown in fig. 1, the first temperature detecting device 7 is used to detect the temperature of the preheating component 2. Of course, the first temperature detection means 7 may also be used for detecting the preheating temperature of the preheating assembly 2, and/or for detecting the inlet temperature of the heating assembly 3, and/or for detecting the inlet temperature of the preheating assembly 2. I.e. the preset temperature parameters comprise the temperature of the preheating component 2, the preheating temperature of the preheating component 2, the inlet temperature of the heating component 3, the inlet temperature of the preheating component 2, etc. In the actual process, the one or more parameters may be set as preset temperature parameters according to the need.

For example, the preset temperature parameter may be specifically the temperature of the preheating assembly 2. The temperature of the preheating component 2 is detected to know the heat accumulated in advance by the preheating component 2, and generally, when the preheating component 2 reaches the preset temperature, the heat accumulation of the preheating component 2 reaches the preset energy value, so that the preheating capacity of the preheating component 2 can be determined by detecting the temperature, the liquid temperature after passing through the preheating component 2 can be calculated according to the temperature T0 of the liquid supply port, and then the liquid heated by the heating component 3 can be ensured to reach the boiling state, so that the high-boiling liquid outlet is realized. On the contrary, if the temperature of the preheating component 2 is lower than the preset temperature, the preheating component 2 fails to be charged completely, and the preheating efficiency is reduced, so that the liquid inlet flow rate can be moderately reduced according to the temperature of the liquid in the liquid container and the like, the preheating power of the preheating component 2 is reduced, and the low-flow boiling liquid outlet is realized through the heating component 3.

In any of the above embodiments, as shown in fig. 1, the liquid treatment system further includes: a second temperature detecting device 6 for detecting the temperature T0 of the liquid supply port; and a controller 8, configured to determine whether to control the rate of the liquid passing through the heating element by the heating element 3 based on the temperature T0 of the liquid supply port when the parameter detected by the first temperature detecting device 7 is less than the preset temperature threshold, and control the heating element 3 to operate at full power when the temperature T0 of the liquid supply port is determined to be less than the set value of the liquid supply port, control the rate of the liquid passing through the heating element by the heating element 3, and enable the heating element 3 to output the liquid at the target temperature.

In this embodiment, the second temperature detecting device 6 is configured to detect the temperature T0 of the liquid supply port, for example, for a product in which the liquid supply port is a liquid container, the temperature T0 of the liquid supply port is the temperature of the liquid in the liquid container. The liquid outlet flow rate of the heating assembly 3 can be reasonably controlled through the monitoring of the liquid temperature of the liquid in the liquid container and the like by the second temperature detection device 6 and the monitoring of the temperature and other parameters of the preheating assembly 2 by the first temperature detection device 7, so that the liquid outlet flow rate is larger than the liquid outlet flow rate provided by the single heating assembly 3 while the liquid outlet temperature is not lower than the target temperature. Meanwhile, the scheme also considers the influence of the liquid supply port, eliminates the liquid outlet temperature difference caused by the liquid supply port temperature difference, thereby improving the liquid outlet control precision and ensuring the liquid outlet temperature stability.

In any of the above embodiments, the liquid treatment system further includes a duration detecting device for detecting a duration of the liquid outlet of the heating assembly 3 or a duration of an interval of the heating assembly 3 from the last liquid outlet. The length of each tapping or the length of the interval between two adjacent tapping can be detected by the length detection device, and the single tapping time can be determined by the length detection, and the tapping time can affect the preheating capacity of the preheating component 2, because generally, the preheating capacity gradually decreases with the lengthening of the tapping time, or the preheating capacity also decreases due to the too short interval. Therefore, the preheating capacity of the preheating component 2 can be predicted by monitoring the liquid outlet time length or the liquid outlet interval time length, whether the current condition can meet the set large-flow liquid outlet or not can be predicted and judged, and if the current condition cannot meet the set large-flow liquid outlet, the speed of liquid passing through the heating component can be reduced. This arrangement, taking into account the preheating effect of the length of the tapping on the preheating assembly 2, eliminates the occurrence of insufficient tapping temperature caused by the decrease in preheating capacity of the preheating assembly 2 due to the tapping for a long time, and ensures that the tapping can be heated to the desired temperature while ensuring a large flow of tapping.

In any of the above embodiments, as shown in fig. 1, the liquid treatment system further comprises a flow control device 4. A flow control device 4 is arranged between the liquid supply port and the preheating assembly 2. A controller 8 is coupled to the flow control device 4 for regulating the rate of liquid flow through the heating assembly by regulating the operation of the flow control device 4. When the liquid outlet flow rate of the heating assembly 3 is reasonably controlled by the monitoring of the liquid temperature of the liquid container and the temperature of the preheating assembly 2 through the second temperature detecting device 6, the liquid outlet flow rate can be reasonably controlled by controlling the flow rate of the flow control device 4 to regulate the liquid amount entering the heating assembly 3.

Further, the flow control device 4 may be a liquid pump, and the liquid pump may be arranged to control the flow, and increase the supply pressure, so as to avoid insufficient supply due to insufficient hydraulic pressure.

In another embodiment, the flow control device 4 includes a flow rate adjusting valve, that is, a flow rate adjusting valve or the like may be provided instead of the liquid pump to adjust the passing liquid amount, so that the control of the liquid outlet flow rate may be realized.

In either of the above embodiments, as shown in fig. 1 and 2, the preheating assembly 2 includes heat exchanging components. The heat exchange component includes a liquid line 22. The liquid pipe 22 is arranged between the liquid supply port and the heating assembly 3, and the connection between the liquid supply port and the heating assembly 3 is realized. The liquid pipeline 22 is used for preheating the liquid conveyed from the liquid supply port and conveying the preheated liquid to the heating assembly 3. Meanwhile, the preheating assembly 2 further comprises a heat storage component 24, wherein the heat storage component 24 has a certain heat storage capacity and can store heat for subsequent use. When the liquid is needed to be discharged, the heat storage component 24 exchanges heat with the liquid in the liquid pipeline 22, namely when the liquid is needed to be discharged, the heat stored in the heat storage component 24 is transferred to the liquid in the liquid pipeline 22, so that the liquid is preheated. Meanwhile, the preheating assembly 2 further includes a heating part 26. The heating unit 26 is used for heating the heat storage unit 24 so that the heat storage unit 24 can continuously store heat, and one heating unit 26 can heat when no liquid is discharged so that the heat storage unit 24 stores heat, and can heat with smaller power based on power distribution in a heating state so that the preheating time of the preheating assembly 2 can be prolonged, thereby the continuous liquid discharging time of the product can be prolonged, and the boiling liquid can be continuously supplied for a longer time and at a large flow rate.

In any of the above embodiments, as shown in fig. 2, the preheating assembly 2 includes a thermal insulation member 28. The heat preservation part 28 wraps the heat exchange part, and the heat preservation part 28 is used for preserving heat of the heat exchange part. By providing the heat-preserving member 28, the heat-preserving efficiency of the heat-exchanging member can be improved, and the heat loss of the heat-exchanging member can be avoided, so that the power required for maintaining the temperature of the heat-exchanging member can be reduced, thereby reducing the energy consumption of the product. Meanwhile, the heat-preserving effect of the heat-exchanging component is good, so that the heat-exchanging component can be used for a longer time under the condition of the same heat-accumulating capacity, and the continuous liquid outlet time of the product can be prolonged.

In any of the above embodiments, the heating element 26 may be provided in a variety of similar forms as desired, such as, for example, one or more of thick film, resistive wire, ceramic heater plate, etc. in particular. And most preferably, the heating element 26 is a resistance wire, which is relatively common, thereby reducing the cost of the product. Further, the heating component 26 is disposed inside the heat exchange component, that is, the heating component 26 directly heats inside the heat exchange component, so that heat loss of the heating component 26 can be avoided, and heating efficiency of the heating component 26 can be improved.

Wherein the preheating component 2 is of a modularized structure. The preheating assembly 2 is detachably installed between the liquid supply port and the heating assembly 3. That is, the preheating component 2 is an optional structure, and can be set according to the requirement, when preheating is not needed, the preheating component 2 can be disassembled, or when leaving the factory, the preheating component 2 is not assembled.

In any of the above embodiments, the thermal storage medium, such as a phase change material or the like, is provided within the thermal storage member 24. And the heating member 26 is specifically for heating the heat storage medium so that the heat storage medium stores heat.

In any of the above embodiments, the type of thermal storage medium may be provided as desired, such as one or more of thermal oil, water, or phase change material. In general, the thermal storage medium is a phase change material because the phase change material has better thermal storage capacity and is better to install and store. Of course, it is also possible that the heat storage medium is provided as heat conducting oil, water. Or the thermal storage medium may be a combination of media such as a combination of different phase change materials, or a combination of phase change materials with thermally conductive oil or water.

In any of the above embodiments, as shown in fig. 2, the heat storage member 24 includes a phase change material for storing heat, the liquid pipe 22 is disposed inside the phase change material, the heating member 26 is disposed on one side of the phase change material to heat the phase change material, and a third temperature detecting device for detecting a temperature of the phase change material is disposed on the other side of the phase change material, and the temperature of the phase change material detected by the third temperature detecting device is a temperature of the preheating assembly 2.

In these embodiments, the thermal storage member 24 comprises a phase change material, the liquid line 22 is disposed inside the phase change material, and the heating member 26 is disposed on one side of the phase change material, and at this time, a third temperature detecting device may be disposed on the other side of the phase change material to detect the temperature of the phase change material. The temperature is the temperature of the preheating component 2, and the heat storage capacity of the preheating component 2 can be determined through the temperature, so that the flow control of the product can be performed by combining the temperature.

In any of the above embodiments, the liquid of the liquid treatment system is passed through the heating assembly at a rate of 7.3g/s or greater, or the liquid of the liquid treatment system is passed through the heating assembly at a rate of 9g/s or greater and 13g/s or less.

In this embodiment, the preheating of the preheating assembly 2 enables a liquid flow rate through the heating assembly of 7.3g/s or more, i.e. in the present application the minimum liquid exit rate is 7.3g/s or more. In the related art, the instant heating type product cannot achieve a liquid outlet rate of 7.3g/s, so that the liquid of the product passes through the heating component at a slower rate, and the experience of a user is seriously reduced. In the application, the speed of liquid passing through the heating component is higher than that of similar products in the related technology, so that the speed of the products is improved, the user experience is improved, and the products are ensured to realize large-flow liquid discharge.

In any of the above embodiments, the preheating module 2 stores heat in advance in a non-heating state, and keeps the temperature until the heat is stored to saturation. Of course, if the product has a short discharge interval between the two passes, the preheating assembly 2 may begin to preheat without heat accumulation to saturation. However, in summary, the preheating assembly 2 is directly subjected to heat accumulation until saturated as long as it is in a non-heating state, so as to be ready for subsequent preheating in advance. In order to ensure the heat storage efficiency, the preheating module 2 stores heat at full power in the non-heating state, that is, at the maximum power allowable by the preheating module 2. Meanwhile, in the heating state, if the heating element 3 heats at a non-full power, that is, there is a surplus of the target power value P set according to the regulations, the preheating element 2 may be controlled to store heat at the surplus power, that is, at this time, both the heating element 3 and the preheating element 2 are in a power consumption state, and the power consumption of the two together is less than or equal to the value required by the regulations, for example, the target power value P. In this arrangement, since the preheating component 2 is also in the heating state in the normal heating state, the preheating component 2 can preheat the liquid and store heat, so that the preheating capability of the preheating component 2 can be prolonged, and the liquid with the target temperature can be continuously output for a longer time, thereby realizing the large-flow long-time liquid discharge.

In any of the above embodiments, as shown in fig. 1, the liquid treatment system further comprises a liquid outlet assembly 5. The liquid outlet component 5 is connected with the heating component 3 and is used for outputting the liquid heated by the heating component 3. The liquid outlet component 5 is a liquid outlet nozzle of the product, and when the user uses the liquid outlet component 5, liquid can be received. Further, the liquid outlet component 5 and the heating component 3 may be directly connected or indirectly connected, that is, the liquid heated by the heating component 3 may be directly discharged through the liquid outlet component 5, or may be treated by a heat exchange device or other devices and then discharged through the liquid outlet component 5.

In any of the above embodiments, as shown in fig. 1, the liquid treatment system comprises a liquid container. The liquid container is arranged to store liquid in advance, so that structures such as an external water pipe are not needed, the placing position of the product is more flexible, and the requirements of a desktop water dispenser and the like are met. Of course, the product may not be provided with a liquid container, and the liquid treatment system may include a connection tube that may be connected to an external liquid source to deliver liquid from the external liquid source to the preheating assembly 2.

Further, the heating component 3 may be an instant heating component or a non-instant heating component, and the instant heating component can rapidly heat the liquid to boil, so as to achieve the effect of instant heating and instant drinking. Instead of the instant heating type assembly, the liquid can be output after the instant heating type assembly is heated to boiling, and the instant heating type assembly can not be used for instant drinking, but the output liquid temperature can be suitable for people to drink. The heating assembly 3 may be configured to be instant heating, or not instant heating, as desired, when specifically configured. Wherein the instant heating assembly 3 may be a thick mode heating tube or a PTC tube.

Further, the liquid treatment system is an instant heating vessel. Still further, the liquid treatment system further comprises a heat exchange device arranged between the liquid outlet assembly 5 and the heating assembly 3 for heating the heating assembly 3 to a temperature at which the boiled liquid is cooled to a temperature at which the boiled liquid is convenient for direct drinking for users.

Generally, when the preheating component 2 reaches the preset temperature, the preheating component 2 stores heat to reach the preset energy value, and the liquid temperature after passing through the preheating component 2 can be calculated according to the temperature of the liquid container 1, and then the high boiling liquid outlet can be realized through the heating component 3. When the temperature of the preheating component 2 is lower than the preset temperature, the preheating component 2 fails to charge energy, the preheating efficiency is reduced, the liquid inlet flow rate is moderately reduced according to the temperature of the liquid container 1, the preheating power of the preheating component 2 is reduced, and the low-flow boiling liquid outlet is realized through the heating component 3.

wherein, the heat preservation part 28 wraps up outside whole heat accumulation, heat exchange part, reduces the dissipation in the heat environment, simultaneously, avoids local high temperature to produce ageing, deformation etc. influence to the structure.

Further, the heating element 3 is a heating means such as a thick film, a resistance wire, a ceramic heating plate, etc.

Furthermore, the liquid treatment system can be applied to a discontinuous drinking liquid system, and the boiling liquid requirement of larger flow is realized by preheating the room-temperature liquid to a certain temperature and then heating to boiling through the boiling module by utilizing the heat storage and heat exchange characteristics of the phase change material.

An embodiment of the second aspect of the present invention provides a control method for a liquid treatment system, which is used in the liquid treatment system (the structure of which is shown in fig. 1 and 2) provided in the embodiment of the first aspect. As shown in fig. 3, the control method includes:

s302: acquiring preset temperature parameters detected by a first temperature detection device;

rate adjustment step S304: judging whether the preset temperature parameter is smaller than a preset temperature threshold, and controlling the heating assembly to operate at full power when the preset temperature parameter is smaller than the preset temperature threshold, controlling the speed of liquid passing through the heating assembly and enabling the heating assembly to output liquid with target temperature; wherein the preset temperature parameter comprises at least one of the following: the temperature of the preheating component, the preheating temperature of the preheating component, the inlet temperature of the heating component, the inlet temperature of the preheating component.

Embodiments of the second aspect of the present invention provide a control method for a liquid treatment system, which is used for the liquid treatment system provided by the embodiments of the first aspect. The liquid processing system comprises a liquid supply port, a preheating component, a heating component, a first temperature detection device and a controller. The liquid treatment system can be a table-top water dispenser, and further a table-top direct-drinking water dispenser, namely a water dispenser which directly outputs liquid after being boiled or a water dispenser which outputs the liquid after being boiled and is adjusted to be suitable for temperature output after drinking. Specifically, the preheating unit is connected to the liquid supply port, and is intended to accumulate heat when the user is not using liquid such as water at ordinary times, that is, when the user is in an idle state, and then, when the user is using liquid such as water, the liquid supplied from the liquid supply port is preheated to a predetermined temperature by storing the accumulated energy in advance, and the preheated liquid is quickly heated to boiling by the heating unit. The liquid heated to boiling is discharged through the liquid outlet component, or the liquid heated to boiling can also exchange heat or be discharged after being combined with other liquids. The first temperature detecting device is used for detecting parameters such as the temperature of the preheating component, the temperature after the preheating component is preheated or the inlet and outlet temperature of the heating component, the inlet temperature of the preheating component and the like, and comparing the parameters with a preset temperature threshold value to judge whether the current state of the liquid treatment system can meet the preset flow (namely, the preset large flow) liquid outlet or not, for example, when the detected temperature is smaller than the preset temperature threshold value, the current state is indicated to not meet the preset large flow liquid outlet, and at the moment, the controller is required to adjust the heating power of the heating component or the speed of the liquid passing through the heating component so as to ensure that the temperature of the output liquid can meet the preset liquid outlet temperature requirement. Therefore, through the monitoring of parameters such as the temperature of the preheating component, the temperature after the preheating component is preheated or the inlet and outlet temperature of the heating component, the inlet temperature of the preheating component, on one hand, the preset large-flow liquid outlet can be met maximally, on the other hand, the temperature of the output liquid can be ensured to meet the preset liquid outlet temperature requirement, so that the large-flow liquid outlet control of the product is realized, and the use experience of a user is further improved.

In any of the above embodiments, as shown in fig. 4, the rate adjustment step, that is, S304 includes:

s3042, obtaining the liquid temperature at the liquid supply port;

s3044, when the preset temperature parameter is smaller than the preset temperature threshold value, determining whether to control the speed of the liquid passing through the heating component or not based on the liquid temperature at the liquid supply port;

s3046, when the liquid temperature at the liquid supply port is determined to be smaller than the liquid supply temperature set value, controlling the heating assembly to operate at full power, controlling the speed of liquid passing through the heating assembly and enabling the heating assembly to output liquid with target temperature;

s3048, when the liquid temperature at the liquid supply port is larger than or equal to the liquid supply temperature set value, the liquid outlet flow is kept unchanged or increased, and the heating component outputs the liquid with the target temperature.

In these embodiments, the liquid processing system further includes a second temperature detecting device for detecting a temperature of the liquid at the liquid supply port, for example, for a product in which the liquid processing system includes a liquid container, the temperature of the liquid at the liquid supply port is a temperature of the liquid in the liquid container. And when the speed is specifically regulated, firstly acquiring the liquid temperature at the liquid supply port, if the preset temperature parameter is smaller than the preset temperature threshold value, indicating that the preset large-flow liquid outlet can not be realized, at this time, if the liquid temperature at the liquid supply port is also lower, controlling the heating assembly to perform full-power heating, then determining the allowable maximum liquid passing speed of the heating assembly according to the actual situation, and carrying out liquid outlet at the allowable maximum liquid passing speed of the heating assembly. However, if the liquid temperature at the liquid supply port is greater than the set value, it is indicated that the liquid temperature at the liquid supply port is higher, so that the liquid outlet flow rate can be kept unchanged or increased according to the actual situation, and the heating assembly can output the liquid with the target temperature. The liquid supply temperature set value can be reasonably set according to actual conditions and by combining preset parameters such as large flow and the like. According to the scheme, the liquid temperature of the liquid in the liquid container and the like is monitored through the second temperature detection device, and the liquid outlet flow of the heating assembly can be reasonably controlled through the monitoring of the temperature and other parameters of the preheating assembly through the first temperature detection device, so that the liquid outlet flow is larger than the liquid outlet flow provided by the single heating assembly while the liquid outlet temperature is not lower than the target temperature. Meanwhile, the scheme also considers the influence of the liquid temperature at the liquid supply port, eliminates the liquid outlet temperature difference caused by the liquid temperature difference at the liquid supply port, thereby improving the liquid outlet control precision and ensuring the stability of the liquid outlet temperature.

In any of the above embodiments, the preset temperature parameter includes a temperature of the preheating component and an inlet temperature of the preheating component, and the rate adjusting step includes: when the inlet temperature of the preheating component is less than or equal to a first preset temperature threshold value, controlling the heating component to operate at full power, controlling the speed of liquid passing through the heating component and enabling the heating component to output liquid with target temperature; determining whether to control the rate of liquid passing through the heating assembly based on the temperature of the preheating assembly when the inlet temperature of the preheating assembly is greater than a first preset temperature threshold; when the temperature of the preheating component is determined to be smaller than the temperature set value of the preheating component, controlling the heating component to operate at full power, controlling the speed of liquid passing through the heating component and enabling the heating component to output liquid with target temperature; when the temperature of the preheating component is greater than or equal to the preset value of the temperature of the preheating component, the liquid outlet flow is kept unchanged or increased, and the heating component outputs the liquid with the target temperature.

In these embodiments, when the inlet temperature of the preheating component is less than or equal to the first preset temperature threshold, the heating component is controlled to operate at full power, and the speed of the liquid passing through the heating component is reasonably controlled, so as to ensure that the output liquid meets the requirement of liquid outlet. If the inlet temperature of the preheating assembly is greater, i.e., greater than a first preset temperature threshold, then it is further determined whether a rate adjustment is to be made in conjunction with the temperature of the preheating assembly itself. For example, when the temperature of the preheating component is smaller than the preset value of the preheating component, the heat storage capacity is insufficient, so that the heating component is controlled to operate at full power, and when the temperature of the preheating component is larger than or equal to the preset value of the preheating component, that is, the heat storage capacity is sufficient, the flow can be locally increased or the flow can be kept unchanged. In any case, however, it is ensured that the output liquid meets the liquid output requirement. This approach combines the inlet temperature of the preheating assembly with the temperature of the preheating assembly itself to achieve a reasonable adjustment of the rate. Therefore, the liquid outlet flow rate is larger than that provided by the single heating component while the liquid outlet temperature is not lower than the target temperature. Meanwhile, according to the scheme, the inlet temperature of the preheating component is considered, the liquid outlet temperature difference caused by the liquid temperature difference at the liquid supply port is eliminated, so that the liquid outlet control precision is improved, and the stability of the liquid outlet temperature is ensured.

In any of the above embodiments, the step of controlling the heating assembly to operate at full power, controlling the rate of liquid passing through the heating assembly and causing the heating assembly to output a liquid at a target temperature comprises: judging whether the heating assembly can output liquid with target temperature or not when the heating assembly runs at full power; when the heating assembly is operated at full power and the heating assembly is unable to output the liquid at the target temperature, the liquid outlet flow rate is reduced.

In these embodiments, when the heat storage capacity is insufficient, the heating element is generally controlled to operate at full power, and at this time, it is first determined whether the heating element is capable of outputting the liquid at the target temperature when the heating element is operated at full power, if so, the heating element is operated at full power, or the power is appropriately reduced, or the rate is appropriately increased, and if not, the rate of the liquid passing through the heating element needs to be reduced. That is, the scheme always takes the high-flow liquid outlet as a priority condition, and gradually reduces the speed when the preset high-flow liquid outlet cannot be met, so that the liquid outlet is ensured to meet the temperature requirement.

In any of the above embodiments, the liquid treatment system includes a heating state, and the control method includes: in the heating state, when the heating power W2 of the heating component is smaller than or equal to the target power value P, the preheating component is controlled to store heat by the power W1 of P-W2.

Further, the control method further includes: under the condition that the heating power of the heating component is smaller than or equal to the target power value, obtaining the residual power after subtracting the heating power of the heating component from the target power value; when the residual power is greater than or equal to the rated heat storage power of the preheating component, the preheating component stores heat with the rated heat storage power, and when the residual power is less than the rated heat storage power of the preheating component, the preheating component stores heat with the residual power.

Further, the liquid processing system further includes a liquid collecting box for collecting the liquid output from the heating assembly and a liquid discharging assembly for discharging the liquid collecting box, and the control method further includes: controlling the liquid outlet assembly to output liquid at a first flow rate in response to the liquid outlet instruction; and after the liquid amount in the liquid collecting box is smaller than the preset flow, controlling the liquid outlet assembly to carry out liquid outlet at a second flow rate, wherein the second flow rate is smaller than the first flow rate.

In these aspects, the liquid handling system further comprises a liquid collection box. The liquid collecting box is provided with a constant-flow water outlet valve for stabilizing the flow velocity of the liquid outlet at a preset flow velocity. Through setting up the liquid collecting box and can concentrate the discharge after collecting water, just so can avoid the big problem of a while of liquid outlet speed for a while. That is, in a normal case, after the heated liquid is collected by the liquid collecting box, the liquid is discharged at a preset large flow rate (first flow rate) set in advance. Meanwhile, in the liquid outlet process, the residual liquid amount in the liquid collecting box can be monitored, if the liquid amount is smaller than a set value, the speed of liquid passing through the heating assembly can be reduced, and liquid can be discharged at a second flow rate, so that the liquid outlet continuity is ensured. For example, if the system is maintained in a working state of heating at the third flow rate for a long period of time, the liquid stored in the liquid collecting box gradually decreases, and after the liquid stored in the liquid collecting box decreases to a certain value, the liquid outlet flow rate can be reduced, so that the liquid outlet continuity is ensured.

In another control method, as shown in fig. 5, it includes the steps of:

as shown in fig. 5, another embodiment of the present invention provides a control method of a liquid processing system, including:

s500, judging whether a liquid treatment system receives a liquid outlet instruction; if yes, go to 504, if no, go to 502.

S502, in a non-heating state, controlling the preheating component to rapidly store heat with the first heat storage power, and preserving heat with the second heat storage power after heat storage is completed, wherein the second heat storage power is smaller than the first heat storage power.

S504, responding to the liquid outlet instruction, and supplying liquid to the preheating component through a liquid supply port.

S506, preheating the liquid passing through the preheating component.

S508, acquiring preset temperature parameters detected by the first temperature detection device.

S510, judging whether the preset temperature parameter is smaller than a preset temperature threshold value; if yes, go to S512, if no, go to 514.

S512, controlling the heating assembly to operate at full power, controlling the speed of liquid passing through the heating assembly and enabling the heating assembly to output liquid with target temperature; the preset temperature parameter includes at least one of: the temperature of the preheating component, the preheating temperature of the preheating component, the inlet temperature of the heating component, the inlet temperature of the preheating component.

S514, keeping the liquid outlet flow unchanged or increasing the liquid outlet flow.

In these embodiments, the liquid handling system includes a non-heated state, i.e., an idle state when the user is not receiving liquid. In this state, the preheating module performs full-power (first regenerative power) heating at its own set maximum power so as to be able to rapidly accumulate full heat. And after full heat is accumulated, the power can be reduced (second heat storage power) to perform heat preservation. Therefore, the preheating component can be ensured to be in a state of storing full heat for a long time, and the preheating component can be ensured to preheat liquid to a required temperature in time when a user needs the liquid such as water.

In any of the foregoing embodiments, the control method further includes: and in response to the preset time of starting, the liquid treatment system is in a heating limiting state, and the preheating component is subjected to full-power heat accumulation.

In these embodiments, when the liquid processing system is just started, the preheating component is not capable of accumulating heat, so that the requirement of large-flow liquid outlet cannot be met basically in a period of just started, and therefore, a start protection period is set, that is, the liquid processing system is in a limited heating state in a period of just started, so that the preheating component can accumulate heat for a long time. The preset time is reasonably set according to the time from heat accumulation to saturation required by the preheating component. At this stage, the preheating assembly can be rapidly stored at full power so as to be capable of rapidly storing heat to a saturated state.

In any of the foregoing embodiments, before the obtaining the preset temperature parameter and performing the rate adjustment step, the method further includes: when a liquid outlet instruction is obtained, detecting a time interval from the last liquid outlet; when the time interval is greater than or equal to the preset interval, executing the step of acquiring preset temperature parameters and performing rate adjustment; when the time interval is less than the preset interval, the liquid outlet is limited, or the speed of the liquid passing through the heating component is reduced, and the heating component outputs the liquid with the target temperature.

In these embodiments, when the liquid outlet instruction is obtained, if the interval between the liquid outlet instruction and the last liquid outlet is detected to be shorter, the comparison judgment of the preset temperature parameter is not performed, so that the liquid outlet is directly limited or the speed of the liquid passing through the heating component is reduced, and the heating component outputs the liquid with the target temperature, so that the whole control flow of the product can be simplified. Wherein, here preset interval is greater than or equal to the time that preheating assembly required to heat accumulation from heat accumulation minimum state to saturation, and heat accumulation minimum state is the state that does not basically have the preheating capacity.

In any of the foregoing embodiments, the control method further includes: when a liquid outlet instruction is obtained, judging whether the preheating component is in heat preservation power or judging whether the preheating component is in a heat storage saturation state; when the preheating component is in heat preservation power or in heat storage saturation state, executing the step of acquiring preset temperature parameters and performing rate adjustment; when the preheating component is not in heat preservation power or in heat storage saturation state, limiting liquid outlet or reducing the speed of liquid passing through the heating component and enabling the heating component to output liquid with target temperature.

In this embodiment, when the command for discharging the liquid is detected, it is first determined whether the preheating component is heat-storing, for example, in a heat-preserving state to indicate that the heat-storing is completed, or the temperature of the preheating component is directly detected to determine whether the preheating component is heat-storing to saturation. If yes, the preheating component stores more heat, and can meet the requirement of preset large-flow liquid outlet, at the moment, preset temperature parameters can be acquired first according to a normal flow, and the speed regulation is performed. On the contrary, the preheating component is not saturated in heat accumulation, namely, the insufficient heat accumulation of the preheating component is found, when the liquid is prepared, the comparison judgment of preset temperature parameters is not carried out, the liquid is directly limited to be discharged or the speed of the liquid passing through the heating component is reduced, and the heating component outputs the liquid with the target temperature, so that the whole control flow of the product can be simplified, after all, when the insufficient heat accumulation of the preheating component is carried out, the liquid discharging requirement with large flow rate is generally not met, and therefore, in order to improve the control efficiency, the temperature-related judgment is not carried out, for example, when the liquid is discharged for a long time, or when the continuous liquid discharging interval is shorter, the judgment of temperature detection is not carried out, the liquid is directly limited to be discharged or the speed of the liquid passing through the heating component is reduced, so that the output liquid can meet the target liquid discharging requirement.

In any of the foregoing embodiments, the control method further includes: the liquid supply amount of the liquid supply port is controlled to control the rate of liquid passing through the heating assembly of the liquid processing system.

In these embodiments, the liquid handling system further comprises a flow control device. The flow control device is arranged between the liquid supply port and the preheating component. The controller is connected with the flow control device and is used for adjusting the speed of the liquid passing through the heating assembly by adjusting the operation of the flow control device. When the liquid temperature of the liquid supply port such as the liquid container and the like and the liquid flow rate of the heating assembly are reasonably controlled through the second temperature detection device and the temperature of the preheating assembly, the liquid supply amount can be regulated through controlling the flow rate of the flow control device, so that the liquid flow rate can be reasonably controlled by regulating the liquid amount entering the heating assembly.
