Description
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 instant heating container can quickly heat the t 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 existing water yield is low in electric heating efficiency and heat energy utilization rate, and the liquid passing rate of the direct water dispenser is generally less than 6.5g/s, so that the liquid outlet flow of the existing desktop water dispenser and other products is small, and flow interruption is easy to form, so that the use experience of a user is influenced.
Therefore, it is now desirable to design a new liquid treatment system that increases the rate at which liquid passes through the heating assembly.
Disclosure of Invention
The present invention aims to solve or improve at least one of the above technical problems.
A first aspect of the present invention is to provide a liquid treatment system.
A second aspect of the present invention is to provide a control method for the above-described liquid treatment system.
A third aspect of the present invention is to provide a control device for the above-described liquid treatment system.
A fourth aspect of the present invention is to provide another control device for the above-described liquid treatment system.
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 technical solution of the first aspect of the present invention provides a liquid treatment system, including: a liquid supply port; the preheating assembly is connected with the liquid supply port and used for accumulating heat and preheating liquid from the liquid supply port through the accumulated heat when the liquid treatment system is in a heating state; and the heating component is connected with the preheating component and is used for reheating the liquid preheated by the preheating component.
The liquid treatment system provided by the invention comprises a liquid supply port, a preheating component and a heating component. 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 the energy accumulated in advance, and the preheated liquid is quickly heated to boiling after entering 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. According to the scheme, heat can be accumulated in advance through the preheating component in an idle state (in a non-heating state), when liquid such as water is needed, the liquid is preheated through the heat accumulated in advance by the preheating component, and in a preheating stage, the liquid is preheated by the preheating component without consuming power, so that the heating component still can be heated with maximum allowable power, namely full power, and further high-efficiency heating can be realized under lower power, and more liquid can be heated to boiling at the same time for the power of the same heating component, so that the liquid passing rate of the heating component can be improved, and the problems of low liquid outlet rate and easiness in current interruption of the household desktop water dispenser in the prior scheme are solved. Because, for a liquid treatment system such as a household desktop water dispenser, the highest heating power is required to be limited to 2300W (W is watt, power unit) according to the electrical safety requirements, that is, the heating power of the heating component needs to be equal to or less than 2300W. Under the power, the water outlet speed of the direct water dispenser and the like 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 table top water dispenser and the like is smaller, 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 heating element heats is preheated through preheating element, so its liquid outlet rate is obviously greater than current 6.5g/s to this has just improved the liquid outlet rate of product, has solved the liquid outlet rate of products such as desktop water dispenser in the current scheme and is little, problem of easy cutout.
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 this application, the liquid processing system is in a heating state and a non-heating state, and is defined by whether the heating component and the preheating component 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 a target temperature. For example, the heating state is a state in which liquid is heated by passing through the heating element, and the non-heating state is a state in which no liquid is heated by passing through the heating element.
In any of the above aspects, the liquid treatment system further comprises: and a controller for adjusting the rate of liquid passing through the heating assembly in accordance with the pre-heat temperature of the pre-heat assembly.
In these aspects, the liquid treatment system further comprises a controller. The controller is used to regulate the rate at which liquid passes through the heating assembly. Specifically, how much liquid the heating assembly can heat to a target outlet water temperature, typically a boiling temperature, depends on the preheating temperature of the preheating assembly, i.e., how much liquid the heating assembly can heat to the target outlet water temperature required for boiling, etc., after the preheating temperature is determined. Therefore, the controller can reasonably regulate the speed of the liquid passing through the heating component based on the temperature of the liquid preheated by the preheating component, so that all the output liquid can be heated to the target water outlet temperature (such as boiling). According to the scheme, through monitoring the preheating temperature, the phenomenon that liquid is output without being heated to the target water outlet temperature (such as boiling temperature) due to insufficient preheating capacity of the preheating component and the like can be avoided, so that the output liquid can be always ensured to be heated to the target water outlet temperature such as boiling and the like while the large-flow liquid outlet is realized.
The target outlet water temperature refers to the temperature output by the outlet end of the heating component, wherein the subsequent operations such as liquid outlet regulation and control are considered at the liquid receiving end.
Further, a predetermined relationship between the preheat temperature and the rate at which the liquid passes through the heating assembly is stored within the liquid treatment system. The preset relationship enables the heating assembly to heat the liquid to a target outlet water temperature. The controller is used for adjusting the speed of the liquid passing through the heating component according to the preheating temperature of the preheating component and the preset relation, and the liquid passing through the heating component at the flow rate and preheated to the preheating temperature by the preheating component can be heated to the target water outlet temperature such as boiling by the heating component as the preset relation is set in advance. Specifically, the relation between the preheating temperature and the speed of the liquid passing through the heating assembly can be measured in advance and stored correspondingly, then after the preheating temperature is determined, the speed value of the required liquid passing through the heating assembly can be calculated based on the relation set in advance, and then the product can be controlled to carry out liquid discharging at the calculated speed of the liquid passing through the heating assembly.
Further, the preset relationship is: t1 is greater than or equal to A-P/V × Cp, A is the target of the heating assemblyThe temperature of the discharged water, cp is the specific heat capacity of the liquid, and P is the target power value (generally set according to the safety requirements). In general, cp is 4.2J/g℃and P is 2300W. Thus, in general, T1. Gtoreq.A-547.6/V. Such an arrangement requires that the actual preheat temperature of the preheat assembly not be too low, should be greater than the desired preheat temperature calculated from A, V, P, etc.
In any of the above aspects, the liquid treatment system further comprises: the first temperature detection device is used for detecting the temperature of the liquid supplied by the liquid supply port; the controller is used for adjusting the speed of the liquid passing through the heating component according to the temperature and the preheating temperature.
In these embodiments, the liquid processing system further includes a first temperature detecting device. For detecting the temperature of the liquid supplied by the liquid supply port, which is typically room temperature when the liquid handling system comprises a liquid container. The controller is used for adjusting the speed of the liquid passing through the heating assembly according to the temperature, the preheating temperature and the target water outlet temperature. Wherein, combining the liquid temperature prior to preheating can determine whether the preheating assembly can preheat the current flow of liquid to the preheating temperature. If so, the current flow rate is maintained or the rate of liquid through the heating assembly is increased appropriately. Conversely, if it is determined that the pre-heat assembly is not capable of pre-heating the current flow of liquid to the pre-heat temperature, the rate of liquid passing through the heating assembly may be suitably reduced. The liquid temperature that this kind of scheme can combine liquid feed mouth department adjusts the speed of liquid through heating element rationally, and then makes all the exhaust liquid all can be heated to required target play water temperature such as boiling, just so avoided the condition emergence that liquid temperature is insufficient because of the liquid temperature difference of liquid feed mouth department to just so can guarantee the large-traffic liquid when heating the liquid to required temperature such as boiling.
Further, w2=cp× (a-T 1 ) X V; a is the target outlet water temperature of the heating assembly, and Cp is the specific heat capacity of the liquid.
In any of the above aspects, the liquid treatment system further comprises: and the second temperature detection device is used for detecting the preheating temperature of the preheating component. So that the controller can make corresponding flow adjustments based on the preheat temperature.
In the technical scheme, the second temperature detection device can be specifically arranged at the liquid outlet of the preheating component so as to detect the temperature of the liquid output by the preheating component, and therefore, the degree of the preheating component preheating the liquid can be determined. The temperature can be combined with the heating power of the heating assembly to determine how much liquid can be heated to the target outlet water temperature by the heating assembly, so that the real-time adjustment of the speed of the liquid passing through the heating assembly can be realized, and the large-flow outlet water can be realized to the greatest extent.
Further, the liquid treatment system further comprises: 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.
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 coupled to the flow control device for regulating the rate of liquid passing through the heating assembly by regulating the operation of the flow control device. When the liquid temperature of the liquid supply port is monitored through the first temperature detection device and the speed of the liquid passing through the heating component is reasonably controlled through the monitoring of the preheating temperature of the preheating component, the liquid quantity entering the heating component can be regulated through controlling the flow of the flow control device, so that the speed of the liquid passing through the heating component is reasonably controlled, namely, the speed of the liquid passing through the heating component is mainly 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 rate of liquid passing through the heating assembly may be controlled.
In any of the above embodiments, the rate of liquid passing through the heating element is greater than 7.3g/s, or the rate of liquid passing through the heating element is greater than or equal to 9g/s and less than or equal to 13g/s.
In this technical scheme, through preheating of preheating component for the rate of liquid through heating component can be greater than 7.3g/s, namely in this application, the minimum rate of liquid through heating component is greater than 7.3 g/s. In the related art, the instant heating type product cannot achieve a heating rate of 7.3g/s, so that the rate of liquid of the product passing through the heating component is slower, 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 heating speed of the products is improved, the user experience is improved, and the products are ensured to realize large-flow liquid discharge.

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, wherein the heating component can heat when no liquid is discharged so as to enable the heat storage component to 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.

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 liquid treatment system includes a non-heating state, and the control method includes: in a non-heating state, controlling the preheating component to store heat; responding to the liquid outlet instruction, and supplying liquid to the preheating component through a liquid supply port; preheating the liquid passing through the preheating component; the heating assembly is controlled to heat the liquid flowing through the heating assembly.
According to the control method of the liquid treatment system provided by the invention, the control method is used for the liquid treatment system with the preheating function. The liquid treatment system comprises a liquid supply port, a preheating component, a heating component and the like. In this scheme, when the user does not use liquid such as water at ordinary times, namely when the user is in an idle state, heat is accumulated, then when the user needs liquid such as water, the liquid supplied by the liquid supply port is preheated to a certain temperature by utilizing the energy accumulated in advance, and the preheated liquid enters the heating assembly and is quickly heated to boiling. 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. According to the scheme, in the preheating stage, the preheating component preheats liquid and does not need to consume power, so that the heating component still can heat with maximum allowable power, namely full power, and therefore higher-efficiency heating can be realized under lower power, more liquid can be heated to boiling at the same time for the power of the same heating component, the speed of the liquid passing through the heating component can be improved, and the problems that the liquid outlet speed of a household desktop water dispenser in the prior scheme is low and current is easy to break are solved. Because, for a liquid treatment system such as a household desktop water dispenser, the highest heating power is required to be limited to 2300W (W is watt, power unit) according to the electrical safety requirements, that is, the heating power of the heating component needs to be equal to or less than 2300W. Under the power, the consumption of the electric heating efficiency and the heat energy utilization rate generally causes the liquid flow rate of the liquid such as the direct water dispenser to be less than 6.5g/s through the heating component, thereby causing the phenomenon that the liquid flow of the existing products such as the desktop water dispenser is smaller and the current is easy to cut off. In this application, when setting up heating element's heating power at 2300W, because the liquid before the heating element heats is preheated through preheating element, so its liquid is through heating element's speed is obviously greater than current 6.5g/s to this has just improved the liquid of product through heating element's speed, has solved the liquid of products such as desktop water dispenser in the current scheme and has passed through heating element's speed is little, easy problem of cutting off.
In any of the above technical solutions, in a non-heating state, the step of controlling the preheating component to store heat specifically includes: and in a non-heating state, controlling the preheating component to store heat with the first heat storage power, and when the heat storage state meets a preset state, controlling the preheating component to store heat with the second heat storage power. The first thermal storage power is greater than the second thermal storage power.
In the technical scheme, when the preheating component stores heat, the heat can be stored according to the first heat storage power which is set in advance, and the heat is preserved after the heat is stored to be saturated. In general, in the non-heating state, the preheating component stores heat with full power, that is, with the maximum power allowed by the preheating component, so that the heat storage speed can be ensured, so that the heat storage saturation state can be reached as soon as possible, and thus, the good preheating capability can be ensured in advance, so that the continuous liquid outlet time of the product can be prolonged, or the speed of the liquid of the product passing through the heating component can be increased.
In any of the above technical solutions, the control method further includes: judging whether the speed of the liquid passing through the heating component meets the target water outlet temperature or not based on preset working parameters of the liquid treatment system, and adjusting the speed of the liquid passing through the heating component when the speed of the liquid passing through the heating component does not meet the target water outlet temperature.
In the technical scheme, the speed of the liquid passing through the heating component can be regulated according to the actual parameters of the product, namely, the speed of the liquid passing through the heating component can be increased as much as possible under the condition that the liquid is heated to the target water outlet temperature such as boiling. For example, when the rate of the liquid passing through the heating component (generally, the rate of the large-flow liquid passing through the heating component set in advance) does not meet the target water outlet temperature, the rate of the liquid passing through the heating component is properly reduced, and when the rate of the liquid passing through the heating component can meet the target water outlet temperature, the current rate can be selected to be kept or the rate can be increased, that is, the scheme can reasonably control the rate based on the actual situation, so that the rate can meet the actual requirement, and the user experience can be improved.
In the above technical solution, based on a preset operating parameter of the liquid treatment system, determining whether a rate of liquid passing through the heating assembly meets a target outlet water temperature, and when the rate of liquid passing through the heating assembly does not meet the target outlet water temperature, the step of adjusting the rate of liquid passing through the heating assembly includes: calculating a desired preheat temperature based on the actual heating power of the heating assembly and the predicted rate of liquid passing through the heating assembly; when the required preheating temperature is smaller than the minimum allowable value of the preheating temperature, the preset treatment is carried out so that the value of the preheating temperature is larger than or equal to the minimum allowable value of the preheating temperature. Specifically, the preset process includes at least one of: reducing the rate at which liquid passes through the heating assembly; increasing the preheating temperature of the preheating assembly; the preheating power of the preheating assembly is increased. That is, when the required preheating temperature is smaller than the minimum allowable value of the preheating temperature, it can be determined that the speed of the liquid passing through the heating assembly does not meet the target outlet water temperature, and then the preset treatment can be performed.
In this solution, if the rate of liquid passing through the heating element is desired to be greater, the preheating temperature requirement of the preheating element is greater, that is, the rate of liquid passing through the heating element and the heat storage capacity of the preheating element are positively correlated, so that, when the rate of liquid passing through the heating element is adjusted, in order to be able to heat the liquid at a certain rate (typically, a value of the rate of high-flow liquid passing through the heating element set in advance) to the target outlet water temperature, there is a minimum allowable preheating temperature, that is, if the preheating temperature is lower than this value, it is basically difficult to heat the liquid to a temperature required for boiling or the like. Therefore, in this scheme, the preheating temperature minimum allowable value is set in advance. In the specific speed regulation, the actual heating power of the heating component and the predicted speed of the liquid passing through the heating component can be determined first, wherein the actual heating power and the predicted speed of the liquid passing through the heating component can be constants set in advance or calculated dynamic values. Thereafter, it may be determined, based on the actual heating power of the heating assembly, how much celsius the preheating assembly is required to store the liquid to the target outlet temperature of boiling or the like when the liquid is heated to the target outlet temperature of boiling or the like by the heating assembly, that is, the preheating temperature may be determined, and then it may be determined whether the required temperature can exceed the minimum allowable preheating temperature (the minimum value may be directly preset or may be the minimum required preheating temperature calculated according to A, V, P or the like). If the heat storage capacity of the current preheating component cannot meet the current requirement, the flow rate, the heating power of the heating component, the preheating temperature of the preheating component and the like can be adjusted, for example, the rate of liquid passing through the heating component is reduced, the preheating power of the preheating component is increased, the preheating power of the preheating component is made to be larger than a preset value, or the preheating temperature of the preheating component is increased, the preheating temperature of the preheating component is made to be larger than a preheating temperature set value and the like until the required preheating temperature value is larger than or equal to the preheating temperature minimum allowable value. According to the scheme, the output liquid can be ensured to meet the current temperature requirement, and the phenomenon that the liquid is output without being heated to the target water outlet temperature required by boiling and the like due to the fact that the speed of the liquid passing through the heating component, the heating power of the heating component and the like are unsuitable is avoided, for example, the phenomenon that the liquid is output without being boiled is avoided.
In yet another embodiment, the heating power W2 of the heating element may be obtained first, and then the value of the velocity V of the liquid passing through the heating element may be calculated by the formula w2=cp× (a-T1) ×v, and the flow rate of the liquid may be controlled accordingly.
In the above technical solution, based on a preset operating parameter of the liquid treatment system, determining whether a rate of liquid passing through the heating assembly meets a target outlet water temperature, and when the rate of liquid passing through the heating assembly does not meet the target outlet water temperature, the step of adjusting the rate of liquid passing through the heating assembly includes: determining the current preheating power or the current preheating temperature of the preheating component; calculating the maximum allowable speed value of the liquid passing through the heating component according to the current preheating power or the current preheating temperature of the preheating component; the actual rate of liquid passing through the heating assembly is controlled to be less than or equal to the maximum allowable rate value of liquid passing through the heating assembly.
In the technical scheme, the current preheating power or the current preheating temperature of the preheating component is determined in advance, at this time, the maximum allowable speed value of the liquid passing through the heating component corresponding to the current preheating power or the current preheating temperature can be determined based on a formula or a table lookup and the like, that is, the maximum allowable speed value of the liquid passing through the heating component can be determined, namely, how large the flow rate of the liquid can be heated to the boiling target water outlet temperature under the condition of the current preheating power or the current preheating temperature, and the flow rate value is the maximum allowable speed value of the liquid passing through the heating component. When the liquid outlet flow is specifically regulated, the flow is controlled not to exceed the maximum value of the flow, otherwise, the liquid with the target outlet temperature of 100 ℃ and the like cannot be output from the heating component. Therefore, the liquid outlet temperature can meet the required requirement while the preset large-flow liquid outlet is met, and the phenomenon that the liquid is not heated to the target water outlet temperature such as boiling and the like due to the fact that the large flow is set in advance is avoided.
In the above technical solution, based on a preset operating parameter of the liquid treatment system, determining whether a rate of liquid passing through the heating assembly meets a target outlet water temperature, and when the rate of liquid passing through the heating assembly does not meet the target outlet water temperature, the step of adjusting the rate of liquid passing through the heating assembly includes: and calculating a minimum required preheating power value of the preheating component according to the temperature of the liquid at the liquid supply port and the expected speed of the liquid passing through the heating component, and reducing the speed of the liquid passing through the heating component when the actual preheating power of the preheating component is smaller than the minimum required preheating power value.
In the technical scheme, the required preheating power can be calculated in advance according to the liquid temperature at the liquid supply port and the required large flow meter, and the value is the minimum required value of the preheating power. And then, the actual preheating power of the preheating component can be monitored in real time, the actual preheating power of the preheating component and the minimum required value of the preheating power are compared to determine whether the preheating capacity of the current preheating component can heat the required large-flow liquid to the target water outlet temperature, if not, the speed of the liquid passing through the heating component can be correspondingly reduced, so that the large-flow liquid outlet is realized, and meanwhile, the liquid can be ensured to be heated to the target water outlet temperature such as boiling, and the like, so that the liquid outlet temperature can meet the required requirements, and the situation that the liquid is not heated to the target water outlet temperature such as boiling, and the like, due to the fact that the large-flow liquid outlet is arranged in advance, can not occur. Meanwhile, according to the scheme, the influence of the liquid inlet temperature 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 the above technical solution, based on a preset operating parameter of the liquid treatment system, determining whether a rate of liquid passing through the heating assembly meets a target outlet water temperature, and when the rate of liquid passing through the heating assembly does not meet the target outlet water temperature, the step of adjusting the rate of liquid passing through the heating assembly includes: and calculating the maximum allowable speed value of the liquid passing through the heating assembly according to the liquid temperature at the liquid supply port, the actual preheating power of the preheating assembly or the actual preheating temperature, and controlling the actual speed of the liquid passing through the heating assembly to be smaller than or equal to the maximum allowable speed value of the liquid passing through the heating assembly.
In the technical scheme, the maximum running speed can be calculated in advance according to the liquid temperature at the liquid supply port, the actual preheating power of the preheating component or the actual preheating temperature. And then the actual speed of the liquid passing through the heating component is controlled below the allowable maximum speed, so that the liquid can be heated to the target outlet water temperature such as boiling and the like while the high-flow liquid outlet is realized, the liquid outlet temperature can meet the required requirements, and the situation that the liquid is not heated to the target outlet water temperature such as boiling and the like due to the fact that the high-flow liquid outlet is set in advance can be avoided. Meanwhile, according to the scheme, the influence of the liquid temperature at the liquid supply port 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 the above technical solution, based on a preset operating parameter of the liquid treatment system, determining whether a rate of liquid passing through the heating assembly meets a target outlet water temperature, and when the rate of liquid passing through the heating assembly does not meet the target outlet water temperature, the step of adjusting the rate of liquid passing through the heating assembly includes: according to the liquid temperature at the liquid supply port and the set preheating temperature of the preheating component, the minimum required preheating power value of the preheating component is calculated, when the actual preheating power of the preheating component is smaller than the minimum required preheating power value, the speed of liquid passing through the heating component is reduced, when the actual preheating power of the preheating component is larger than or equal to the minimum required preheating power value, the maximum allowable speed of liquid passing through the heating component is calculated, and liquid is discharged at the maximum allowable speed of liquid passing through the heating component.
In the technical scheme, when the required preheating temperature is set in advance to meet the requirement of high-flow liquid discharge, namely the preheating temperature required to be met by the preheating component is limited, the minimum required preheating power value can be calculated based on the liquid temperature at the liquid supply port and the set preheating temperature of the preheating component, when the actual preheating power of the preheating component is smaller than the minimum required preheating power value, the preset high-flow liquid discharge cannot be met at the moment, and when the actual preheating power is larger than the minimum required heating power value, the preset high-flow liquid discharge can be met, the maximum allowable liquid discharge amount can be further calculated at the moment, and then the liquid is discharged at the maximum allowable rate of the liquid passing through the heating component, so that when the high-flow liquid discharge is met, the liquid can be ensured to be heated to the target water discharge temperature such as boiling, and the like, the required requirement can be met, and the situation that the liquid is not heated to the target water discharge temperature such as boiling and the like due to the fact that the high-flow liquid discharge is set in advance can not occur is avoided. 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 the above technical solution, based on a preset operating parameter of the liquid treatment system, determining whether a rate of liquid passing through the heating assembly meets a target outlet water temperature, and when the rate of liquid passing through the heating assembly does not meet the target outlet water temperature, the step of adjusting the rate of liquid passing through the heating assembly includes: storing a preset relationship between a preheating temperature of the preheating assembly and a rate at which the liquid passes through the heating assembly; and calculating the corresponding speed of the liquid passing through the heating assembly according to the preset relation, and controlling the liquid treatment system to carry out liquid discharging at the calculated speed of the liquid passing through the heating assembly.
In this embodiment, the liquid treatment system has stored therein a predetermined relationship between the preheat temperature and the rate at which the liquid passes through the heating assembly. The preset relationship enables the heating assembly to heat the liquid to a target outlet water temperature. The controller is used for adjusting the speed of the liquid passing through the heating component according to the preheating temperature of the preheating component and the preset relation, and the liquid passing through the heating component at the flow rate and preheated to the preheating temperature by the preheating component can be heated to the target water outlet temperature such as boiling by the heating component as the preset relation is set in advance. Specifically, the relation between the preheating temperature and the speed of the liquid passing through the heating assembly can be measured in advance and stored correspondingly, then after the preheating temperature is determined, the speed value of the required liquid passing through the heating assembly can be calculated based on the relation set in advance, and then the product can be controlled to carry out liquid discharging at the calculated speed of the liquid passing through the heating assembly.
Further, the preset relationship includes: t1 is more than or equal to A-P/V multiplied by Cp, A is the target water outlet temperature of the heating component, cp is the specific heat capacity of liquid, and P is the target power value (generally set according to the safety requirements). In general, cp is 4.2J/g℃and P is 2300W. Thus, in general, T1. Gtoreq.A-547.6/V. Such an arrangement requires that the actual preheat temperature of the preheat assembly not be too low, should be greater than the desired preheat temperature calculated from A, V, P, etc.
In the above technical solution, the step of storing a preset relationship between the preheating temperature and the rate of liquid passing through the heating assembly includes: and storing a correlation table formed by the value of the preheating temperature of the preheating component and the value of the speed of the liquid passing through the heating component so as to form a preset relation.
In the technical scheme, the corresponding relation between the preheating temperature and the speed V of the liquid passing through the heating component is preset, after the preheating temperature is obtained, the required liquid outlet flow can be obtained through table lookup according to the corresponding relation of T1-V, and then the liquid outlet flow can be controlled based on the liquid outlet flow value obtained through table lookup.
In the above technical solution, in the heating state, when the heating power of the heating element is less than or equal to the target power value, a power difference between the target power value and the heating power of the heating element is calculated, and the preheating element is controlled to store heat according to the power difference.
In these embodiments, the liquid treatment system includes a heated 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 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 when 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 the target water outlet temperature can be continuously output for a longer time, so that the liquid with a large flow rate and long time can be discharged.
Further, w2=cp× (a-T1) ×v, a is the target outlet water temperature of the heating element, and Cp is the specific heat capacity of the liquid. The heating power required by the heating assembly to heat the liquid to the target outlet water temperature can be calculated by this formula.
Further, P is 2300W. This ensures that the sum of the powers does not exceed the specified requirements when the preheating assembly and the heating assembly are simultaneously heated.
Further, w2=cp× (a-T 1 ) X V, W2 is the heating power of the heating element, a is the target outlet water temperature of the heating element, cp is the specific heat capacity of the liquid, V is the rate at which the liquid passes through the heating element.
In the technical scheme, when the target water outlet temperature, the heating power W2 of the heating component and any three values of the speed of the liquid passing through the heating component and the preheating temperature are known, the other value can be calculated according to the above, so that the liquid outlet flow can be reasonably controlled based on the relation of T1, V and W2, and the large-flow liquid outlet can be ensured.
Further, the preheating component has heat accumulation total heat energy of Q, preheating power of W3, heating component power of W2, total power of W0, speed of liquid passing through the heating component of V, room temperature liquid temperature of T0, liquid temperature after preheating of T1 and specific heat of Cp (4.2J/g ℃). When the target water outlet temperature of the system is 100 ℃ and the heating power of the product cannot exceed 2300W according to the electricity utilization rule, the following relation is satisfied by each parameter:
W2=cp× (100 ℃ -T1) ×v is equal to or less than 2300 (formula 1)
W3+w2=cp× (100 ℃ -T0) ×v (formula 2)
W0=w3+w2 is not less than 2300 (formula 3)
While it can be derived from equations 1 through 3 that if the rate of high flow of liquid through the heating assembly is satisfied, then V and T1 should satisfy: t1 is more than or equal to 100-547.6/V. Therefore, in the application, the preset relation is set to be T1 to be more than or equal to 100-547.6/V, so that the speed of high-flow liquid passing through the heating assembly can be met. According to the relation, after the preheating temperature is detected, the speed of the corresponding liquid passing through the heating component can be known, so that the liquid outlet can be controlled according to the calculated speed, the maximum flow of the boiled liquid can be improved, the structure is reasonable, the flow of the boiled liquid is increased, and the service performance is improved.
In any of the above solutions, the liquid treatment system includes a non-heating state, and the control method further includes: and in a non-heating state, controlling the preheating component to rapidly 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 second heat storage power is smaller than the first heat storage power.
In these embodiments, the liquid treatment system includes a non-heating state, which generally corresponds to a non-water-out state, i.e., a state in which no water is required. 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.
A third aspect of the present invention provides a control device for a liquid treatment system, for the liquid treatment system provided in any one of the first aspect, the liquid treatment system including a non-heating state, the control device including a determination unit and a control unit, the determination unit being configured to determine a state of the liquid treatment system, the state of the liquid treatment system including a heating state and a non-heating state.

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 and 2.
As shown in fig. 1, embodiment 1 of the first aspect of the present invention provides a liquid treatment system, including: a liquid supply port (arranged on the liquid container 1), a preheating component 2 and a heating component 3. The preheating component 2 is connected with the liquid supply port and used for storing heat, and when the liquid treatment system is in a heating state, the liquid conveyed by the liquid supply port is preheated. The heating component 3 is connected with the preheating component 2 and is used for reheating the liquid preheated by the preheating component 2.
According to the liquid treatment system provided by the invention, heat can be accumulated in advance through the preheating component 2 in an idle state (non-heating state), and when liquid such as water is needed, the liquid is preheated through the heat accumulated in advance by the preheating component 2, and in the preheating stage, the liquid is preheated by the preheating component 2, and power is not required to be consumed, so that higher-efficiency heating can be realized under lower power, more liquid can be heated to boiling at the same power of the heating component 3, the speed of the liquid passing through the heating component can be improved, and the problems of low liquid outlet speed and easiness in flow interruption of the household table top water dispenser in the prior scheme are solved. Because, for a liquid treatment system such as a household table-top water dispenser, the highest heating power is required to be limited to 2300W (W is watt, power unit) according to the electrical safety requirements, that is, the heating power of the heating assembly 3 needs to be equal to or less than 2300W. Under the power, the consumption of the electric heating efficiency and the heat energy utilization rate generally causes the liquid flow rate of the liquid such as the direct water dispenser to be less than 6.5g/s through the heating component, thereby causing the phenomenon that the liquid flow of the existing products such as the desktop water dispenser is smaller and the current is easy to cut off. In this application, when setting up the heating power of heating element 3 at 2300W, because the liquid before heating element 3 heats is preheated through preheating element 2, so its liquid is through heating element's speed is obviously greater than current 6.5g/s to this has just improved the liquid of product and has passed through heating element's speed, has solved the liquid of products such as desktop water dispenser in the current scheme and has passed through heating element's speed little, easy problem of cutting off.
In any of the above embodiments, the liquid treatment system further comprises: a controller (not shown) for adjusting the rate of liquid passing through the heating assembly in accordance with the pre-heat temperature of the pre-heat assembly 2. Specifically, how much liquid the heating assembly 3 can heat to the target outlet water temperature (typically, boiling temperature) depends on the preheating temperature of the preheating assembly 2, that is, how much liquid can be heated to the target outlet water temperature required for boiling or the like after the preheating temperature is determined. Thus, the controller may rationally regulate the rate at which liquid passes through the heating assembly based on the temperature of the liquid after preheating by the preheating assembly 2 so that all of the output liquid can be heated to a target outlet temperature (e.g., boiling). According to the scheme, the phenomenon that liquid is output without being heated to the target water outlet temperature (such as boiling temperature) due to insufficient preheating capacity of the preheating component 2 and the like can be avoided through monitoring the preheating temperature, so that the output liquid can be always heated to the target water outlet temperature such as boiling while realizing large-flow liquid outlet.
Considering that the liquid receiving end involves subsequent operations such as liquid outlet regulation and control, the target outlet water temperature refers to the temperature output by the liquid outlet end of the heating component 3.
Further, a preset relationship between the preheat temperature and the rate V at which the liquid passes through the heating assembly is stored within the liquid treatment system. The preset relationship enables the heating assembly 3 to heat the liquid to the target outlet water temperature. The controller is used for adjusting the speed V of the liquid passing through the heating component according to the preheating temperature of the preheating component 2 and the preset relation, and the liquid passing through the heating component 3 and preheated to the preheating temperature by the preheating component 2 at the flow rate can be heated to the target water outlet temperature such as boiling by the heating component 3 because the preset relation is set in advance. Specifically, the relation between the preheating temperature and the speed V of the liquid passing through the heating assembly can be measured in advance and stored correspondingly, then after the preheating temperature is determined, the speed value of the required liquid passing through the heating assembly can be calculated based on the relation set in advance, and then the product can be controlled to carry out liquid discharging at the calculated speed of the liquid passing through the heating assembly.
Further, the preset relationship is: t1 is more than or equal to A-P/V multiplied by Cp, A is the target water outlet temperature of the heating component 3, cp is the specific heat capacity of liquid, and P is the target power value (generally set according to the safety requirements). In general, cp is 4.2J/g℃and P is 2300W. Thus, in general, T1. Gtoreq.A-547.6/V. This arrangement requires that the actual preheating temperature of the preheating assembly 2 should not be too low, and should be greater than the desired preheating temperature calculated from A, V, P and the like.

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 treatment system includes a non-heated state. As shown in fig. 3, the control method includes:
s302, controlling the preheating component to store heat in a non-heating state;
s304, responding to the liquid outlet instruction, and supplying liquid to the preheating component through a liquid supply port;
s306, preheating the liquid passing through the preheating component, and controlling the heating component to heat the liquid flowing through the heating component.
According to the control method of the liquid treatment system, the preheating component is used for preheating liquid in the preheating stage, and power consumption is not needed, so that the heating component can still heat with maximum allowable power, namely full power, and therefore higher-efficiency heating can be realized under lower power, more liquid can be heated to boiling at the same time for the power of the same heating component, the speed of the liquid passing through the heating component can be improved, and the problems of low liquid outlet speed and easiness in flow interruption of the household desktop water dispenser in the existing scheme are solved. Because, for a liquid treatment system such as a household desktop water dispenser, the highest heating power is required to be limited to 2300W (W is watt, power unit) according to the electrical safety requirements, that is, the heating power of the heating component needs to be equal to or less than 2300W. Under the power, the consumption of the electric heating efficiency and the heat energy utilization rate generally causes the liquid flow rate of the liquid such as the direct water dispenser to be less than 6.5g/s through the heating component, thereby causing the phenomenon that the liquid flow of the existing products such as the desktop water dispenser is smaller and the current is easy to cut off. In this application, when setting up heating element's heating power at 2300W, because the liquid before the heating element heats is preheated through preheating element, so its liquid is through heating element's speed is obviously greater than current 6.5g/s to this has just improved the liquid of product through heating element's speed, has solved the liquid of products such as desktop water dispenser in the current scheme and has passed through heating element's speed is little, easy problem of cutting off.
In any of the foregoing embodiments, S302 specifically includes: and in a non-heating state, controlling the preheating component to store heat with the first heat storage power, and when the heat storage state meets a preset state, controlling the preheating component to store heat with the second heat storage power.
In this embodiment, when the preheating component stores heat, heat may be stored according to the first heat storage power set in advance, and heat may be preserved after the heat is stored to saturation. In general, in the non-heating state, the preheating component stores heat with full power, that is, with the maximum power allowed by the preheating component, so that the heat storage speed can be ensured, so that the heat storage saturation state can be reached as soon as possible, and thus, the good preheating capability can be ensured in advance, so that the continuous liquid outlet time of the product can be prolonged, or the speed of the liquid of the product passing through the heating component can be increased.
As shown in fig. 4, embodiment 2 of the second aspect of the present invention provides a control method of a liquid processing system, including:
s402, controlling the preheating component to store heat in a non-heating state;
s404, responding to the liquid outlet instruction, and supplying liquid to the preheating component through a liquid supply port;
s406, preheating the liquid passing through the preheating component, and controlling the heating component to heat the liquid flowing through the heating component;
S408, judging whether the first speed V of the liquid passing through the heating assembly meets the target water outlet temperature or not based on the preset working parameters of the liquid treatment system, and adjusting the first speed V when the first speed V does not meet the target water outlet temperature.
In this embodiment, the rate of liquid passing through the heating assembly can be adjusted according to the actual parameters of the product, i.e. can be increased as much as possible in the case of heating the liquid to a target outlet water temperature, such as boiling. For example, when the rate V of the liquid passing through the heating assembly does not meet the target water outlet temperature, the rate V of the liquid passing through the heating assembly is properly reduced, and when the rate V of the liquid passing through the heating assembly can meet the target water outlet temperature, the current rate can be selectively maintained or increased, that is, the scheme can reasonably control the rate based on the actual situation, so that the rate can meet the actual requirement, and the user experience can be improved.
In the above embodiment, the step of determining whether the rate V of the liquid passing through the heating assembly meets the target outlet water temperature based on the preset operation parameter of the liquid processing system, and when the rate V of the liquid passing through the heating assembly does not meet the target outlet water temperature, adjusting the rate V of the liquid passing through the heating assembly includes: calculating a desired preheat temperature based on the actual heating power of the heating assembly and the predicted rate of liquid passing through the heating assembly; when the required preheating temperature is smaller than the minimum allowable value of the preheating temperature, the preset treatment is carried out so that the value of the preheating temperature is larger than or equal to the minimum allowable value of the preheating temperature. Specifically, the preset process includes at least one of: reducing the rate at which liquid passes through the heating assembly; increasing the preheating temperature of the preheating assembly; the preheating power of the preheating assembly is increased.
In this embodiment, if the rate at which the liquid passes through the heating assembly is desired to be greater, the preheating temperature requirement of the preheating assembly is greater, i.e., the rate V at which the liquid passes through the heating assembly and the heat storage capacity of the preheating assembly are positively correlated, so that in adjusting the rate at which the liquid passes through the heating assembly, in order to be able to heat the liquid at a rate (typically a pre-set high flow rate value of the liquid passing through the heating assembly) to the target outlet water temperature, there is a minimum allowable preheating temperature, i.e., if the preheating temperature is below that value, it is substantially difficult to heat the liquid to the desired temperature, such as boiling. Therefore, in this scheme, the preheating temperature minimum allowable value is set in advance. In the specific speed regulation, the actual heating power of the heating component and the predicted speed of the liquid passing through the heating component can be determined first, wherein the actual heating power and the predicted speed of the liquid passing through the heating component can be constants set in advance or calculated dynamic values. Thereafter, it may be determined, based on the actual heating power of the heating assembly, how much celsius the preheating assembly is required to store the liquid to the target outlet temperature of boiling or the like when the liquid is heated to the target outlet temperature of boiling or the like by the heating assembly, that is, the preheating temperature may be determined, and then it may be determined whether the required temperature can exceed the minimum allowable preheating temperature (the minimum value may be directly preset or may be the minimum required preheating temperature calculated according to A, V, P or the like). If the heat storage capacity of the current preheating component cannot meet the current requirement, the flow rate, the heating power of the heating component, the preheating temperature of the preheating component and the like can be adjusted, for example, the rate of liquid passing through the heating component is reduced, the preheating power of the preheating component is increased, the preheating power of the preheating component is made to be larger than a preset value, or the preheating temperature of the preheating component is increased, the preheating temperature of the preheating component is made to be larger than a preheating temperature set value and the like until the required preheating temperature value is larger than or equal to the preheating temperature minimum allowable value. According to the scheme, the output liquid can be ensured to meet the current temperature requirement, and the phenomenon that the liquid is output without being heated to the target water outlet temperature required by boiling and the like due to the fact that the speed of the liquid passing through the heating component, the heating power of the heating component and the like are unsuitable is avoided, for example, the phenomenon that the liquid is output without being boiled is avoided.
In the above embodiment, the heating power W2 of the heating element may be obtained first, and then the value of the velocity V of the liquid passing through the heating element may be calculated by the formula w2=cp× (a-T1) ×v, and the flow rate of the liquid may be controlled accordingly.
In the above embodiment, the step of determining whether the rate V of the liquid passing through the heating assembly meets the target outlet water temperature based on the preset operation parameter of the liquid processing system, and when the rate V of the liquid passing through the heating assembly does not meet the target outlet water temperature, adjusting the rate V of the liquid passing through the heating assembly includes: determining the current preheating power or the current preheating temperature of the preheating component; calculating the maximum allowable speed value of the liquid passing through the heating component according to the current preheating power or the current preheating temperature of the preheating component; the actual rate of liquid passing through the heating assembly is controlled to be less than or equal to the maximum allowable rate value of liquid passing through the heating assembly.
In this embodiment, the current preheating power or the current preheating temperature of the preheating component is determined in advance, and at this time, the maximum allowable speed value of the liquid passing through the heating component corresponding to the current preheating power or the current preheating temperature can be determined based on a formula or a table look-up, etc., that is, it is determined how large flow of the liquid can be heated to the boiling target outlet water temperature under the condition of the current preheating power or the current preheating temperature, and the flow value is the maximum allowable speed value of the liquid passing through the heating component. When the liquid outlet flow is specifically regulated, the flow is controlled not to exceed the maximum value of the flow, otherwise, the liquid with the target outlet temperature of 100 ℃ and the like cannot be output from the heating component. Therefore, the liquid outlet temperature can meet the required requirement while the preset large-flow liquid outlet is met, and the phenomenon that the liquid is not heated to the target water outlet temperature such as boiling and the like due to the fact that the large flow is set in advance is avoided.
In the above embodiment, the step of determining whether the rate V of the liquid passing through the heating assembly meets the target outlet water temperature based on the preset operation parameter of the liquid processing system, and when the rate V of the liquid passing through the heating assembly does not meet the target outlet water temperature, adjusting the rate V of the liquid passing through the heating assembly includes: and calculating a minimum required preheating power value of the preheating component according to the temperature of the liquid at the liquid supply port and the expected speed of the liquid passing through the heating component, and reducing the speed of the liquid passing through the heating component when the actual preheating power of the preheating component is smaller than the minimum required preheating power value.
In this embodiment, the required preheating power can be calculated in advance from the liquid temperature at the liquid supply port and the required large flow rate, which is the minimum required value of the preheating power. And then, the actual preheating power of the preheating component can be monitored in real time, the actual preheating power of the preheating component and the minimum required value of the preheating power are compared to determine whether the preheating capacity of the current preheating component can heat the required large-flow liquid to the target water outlet temperature, if not, the speed of the liquid passing through the heating component can be correspondingly reduced, so that the large-flow liquid outlet is realized, and meanwhile, the liquid can be ensured to be heated to the target water outlet temperature such as boiling, and the like, so that the liquid outlet temperature can meet the required requirements, and the situation that the liquid is not heated to the target water outlet temperature such as boiling, and the like, due to the fact that the large-flow liquid outlet is arranged in advance, can not occur. Meanwhile, according to the scheme, the influence of the liquid temperature at the liquid supply port 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 the above embodiment, the step of determining whether the rate V of the liquid passing through the heating assembly meets the target outlet water temperature based on the preset operation parameter of the liquid processing system, and when the rate V of the liquid passing through the heating assembly does not meet the target outlet water temperature, adjusting the rate V of the liquid passing through the heating assembly includes: and calculating the maximum allowable speed value of the liquid passing through the heating assembly according to the liquid temperature at the liquid supply port, the actual preheating power of the preheating assembly or the actual preheating temperature, and controlling the actual speed of the liquid passing through the heating assembly to be smaller than or equal to the maximum allowable speed value of the liquid passing through the heating assembly.
In this embodiment, the maximum rate of operation may be calculated in advance from the liquid temperature at the liquid supply port, the actual preheat power of the preheat assembly, or the actual preheat temperature. And then the actual speed of the liquid passing through the heating component is controlled below the allowable maximum speed, so that the liquid can be heated to the target outlet water temperature such as boiling and the like while the high-flow liquid outlet is realized, the liquid outlet temperature can meet the required requirements, and the situation that the liquid is not heated to the target outlet water temperature such as boiling and the like due to the fact that the high-flow liquid outlet is set in advance can be avoided. Meanwhile, according to the scheme, the influence of the liquid temperature at the liquid supply port 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 the above embodiment, the step of determining whether the rate V of the liquid passing through the heating assembly meets the target outlet water temperature based on the preset operation parameter of the liquid processing system, and when the rate V of the liquid passing through the heating assembly does not meet the target outlet water temperature, adjusting the rate V of the liquid passing through the heating assembly includes: according to the liquid temperature at the liquid supply port and the set preheating temperature of the preheating component, the minimum required preheating power value of the preheating component is calculated, when the actual preheating power of the preheating component is smaller than the minimum required preheating power value, the speed of liquid passing through the heating component is reduced, when the actual preheating power of the preheating component is larger than or equal to the minimum required preheating power value, the maximum allowable speed of liquid passing through the heating component is calculated, and liquid is discharged at the maximum allowable speed of liquid passing through the heating component.
In this embodiment, when the required preheating temperature is set in advance to meet the high-flow liquid outlet, that is, the preheating temperature required to be met by the preheating component is limited, then the minimum required preheating power value can be calculated based on the liquid temperature at the liquid supply port and the set preheating temperature of the preheating component, when the actual preheating power of the preheating component is smaller than the minimum required preheating power value, the preset high-flow liquid outlet cannot be met at this time, and when the actual preheating power is larger than the minimum required preheating power value, the preset high-flow liquid outlet can be met, the maximum allowable liquid outlet amount can be further calculated, and then the liquid can be discharged at the maximum allowable rate when the liquid passes through the heating component, so that when the high-flow liquid outlet is met, the liquid can be ensured to be heated to the target water outlet temperature such as boiling, so as to ensure that the required liquid outlet temperature can meet the requirement, and the situation that the liquid is not heated to the target water outlet temperature such as boiling due to the preset high-flow liquid outlet can not occur. 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 the above embodiment, the step of determining whether the rate V of the liquid passing through the heating assembly meets the target outlet water temperature based on the preset operation parameter of the liquid processing system, and when the rate V of the liquid passing through the heating assembly does not meet the target outlet water temperature, adjusting the rate V of the liquid passing through the heating assembly includes: storing a preset relationship between a preheating temperature of the preheating assembly and a rate at which the liquid passes through the heating assembly; and calculating the corresponding speed of the liquid passing through the heating assembly according to the preset relation, and controlling the liquid treatment system to carry out liquid discharging at the calculated speed of the liquid passing through the heating assembly.
In this embodiment, a preset relationship between the preheat temperature and the rate of liquid flow V through the heating assembly is stored in the liquid treatment system. The preset relationship enables the heating assembly to heat the liquid to a target outlet water temperature. The controller is used for adjusting the speed V of the liquid passing through the heating component according to the preheating temperature of the preheating component and the preset relation, and the liquid passing through the heating component at the flow rate and preheated to the preheating temperature by the preheating component can be heated to the target water outlet temperature such as boiling by the heating component as the preset relation is set in advance. Specifically, the relation between the preheating temperature and the speed V of the liquid passing through the heating assembly can be measured in advance and stored correspondingly, then after the preheating temperature is determined, the speed value of the required liquid passing through the heating assembly can be calculated based on the relation set in advance, and then the product can be controlled to carry out liquid discharging at the calculated speed of the liquid passing through the heating assembly.
Further, the preset relationship includes: t1 is more than or equal to A-P/V multiplied by Cp, A is the target water outlet temperature of the heating component, cp is the specific heat capacity of liquid, and P is the target power value (generally set according to the safety requirements). In general, cp is 4.2J/g℃and P is 2300W. Thus, in general, T1. Gtoreq.A-547.6/V. Such an arrangement requires that the actual preheat temperature of the preheat assembly not be too low, should be greater than the desired preheat temperature calculated from A, V, P, etc.
In the above embodiment, the step of storing the preset relationship between the preheating temperature and the velocity V of the liquid passing through the heating assembly includes: and storing a correlation table formed by the value of the preheating temperature of the preheating component and the value of the speed of the liquid passing through the heating component so as to form a preset relation.
In this embodiment, a correspondence between the preheating temperature and the velocity V of the liquid passing through the heating assembly is preset, after the preheating temperature is obtained, the required liquid outlet flow rate can be obtained by looking up a table according to the correspondence between T1 and V, and then the liquid outlet flow rate can be controlled based on the liquid outlet flow rate value obtained by looking up the table.
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 embodiments, the liquid handling system further comprises a liquid trap. 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.
As shown in fig. 5, embodiment 3 of the second aspect of the present invention provides a control method of a liquid processing system, including:
s502, in a non-heating state, controlling the preheating component to store heat;
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, and controlling the heating component to heat the liquid flowing through the heating component;
s508, judging whether the speed V of the liquid passing through the heating component meets the target water outlet temperature or not based on preset working parameters of the liquid treatment system, and adjusting the speed V of the liquid passing through the heating component when the speed V of the liquid passing through the heating component does not meet the target water outlet temperature;
s510, in a heating state, heating power W2 of the heating assembly is calculated, when W2 is smaller than or equal to a target power value P, the heating assembly is controlled to heat with the calculated power W2, and the preheating assembly is controlled to store heat with the power of P-W2;
s512, 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 the heat storage is completed, wherein the second heat storage power is smaller than the first heat storage power.
In these embodiments, the liquid treatment system includes a non-heated state. 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. Meanwhile, the liquid handling system includes a heating state, for example, a state in which a user receives liquid. 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 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 at the same time, thus the preheating capacity of the preheating component can be prolonged, and the liquid with the target water outlet temperature can be continuously output for a longer time.
Further, w2=cp× (a-T1) ×v, a is the target outlet water temperature of the heating element, and Cp is the specific heat capacity of the liquid. The heating power required by the heating assembly to heat the liquid to the target outlet water temperature can be calculated by this formula.
Further, P is 2300W. This ensures that the sum of the powers does not exceed the specified requirements when the preheating assembly and the heating assembly are simultaneously heated.
Further, w2=cp× (a-T1) ×v, W2 is the heating power of the heating element, a is the target outlet water temperature of the heating element, cp is the specific heat capacity of the liquid, and V is the rate at which the liquid passes through the heating element.
In this embodiment, when the target outlet water temperature, the heating power W2 of the heating assembly, and any three values of the speed of the liquid passing through the heating assembly and the preheating temperature are known, another value can be calculated according to the above, so that the outlet water flow rate can be reasonably controlled based on the relation of T1, V and W2, so as to ensure a large flow rate of outlet water.
Further, the preheating component has heat accumulation total heat energy of Q, preheating power of W3, heating component power of W2, total power of W0, speed of liquid passing through the heating component of V, room temperature liquid temperature of T0, liquid temperature after preheating of T1 and specific heat of Cp (4.2J/g ℃). When the target water outlet temperature of the system is 100 ℃ and the heating power of the product cannot exceed 2300W according to the electricity utilization rule, the following relation is satisfied by each parameter:
W2=cp× (100 ℃ -T1) ×v is equal to or less than 2300 (formula 1)
W3+w2=cp× (100 ℃ -T0) ×v (formula 2)
W0=w3+w2 is not less than 2300 (formula 3)
While from equations 1 through 3 it can be derived that if the velocity V of the bulk liquid through the heating assembly is satisfied, then the ratio between V and T1 should be: t1 is more than or equal to 100-547.6/V. Therefore, in the application, the preset relation is set to be T1 to be more than or equal to 100-547.6/V, so that the speed V of the large-flow liquid passing through the heating component can be met. According to the relation, after the preheating temperature is detected, the speed of the corresponding liquid passing through the heating component can be known, so that the liquid outlet can be controlled according to the calculated speed, the maximum flow of the boiled liquid can be improved, the structure is reasonable, the flow of the boiled liquid is increased, and the service performance is improved.
