According to an aspect of the present application, there is provided a water outlet control method of a water purifier, as shown in fig. 1, the water purifier including a hot water control device 10, a cold water control device 20, a proportional adjustment device 30, a heating device 40, and a hot tank 50, the proportional adjustment device 30 being disposed between an intersection water outlet of the hot water control device 10 and the cold water control device 20 and a water outlet of the water purifier, the heating device 40 being disposed between the proportional adjustment device 30 and the water outlet of the water purifier, as shown in fig. 2, the water outlet control method including:
s10, obtaining a target outlet water temperature.
In this embodiment, the target water temperature may be obtained by selecting a target water temperature input by a user, for example, a water temperature of 45 ℃,60 ℃,85 ℃,90 ℃,100 ℃, or the like, or may be selected by a water outlet function key, for example, a function key for brewing milk, making tea, making coffee, or the like, or may be a water temperature of fixed water temperature, for example, a water temperature of fixed water is 45 ℃,60 ℃,85 ℃,90 ℃,100 ℃. Taking user selection as an example, a user can select target outlet water temperature demand information through an operation panel on the water purifier, and after receiving the demand information of the user, the controller obtains the target outlet water temperature through decoding the information.
S20, judging whether the target outlet water temperature is higher than the hot water temperature in the hot tank. In the present embodiment, the temperature of the hot water in the hot tank 50 is preset in advance, for example, the stable hot water temperature in the hot tank 50 may be 50 ℃, 80 ℃, or the like. After the target water outlet temperature is obtained, comparing the target water outlet temperature with the hot water temperature in the hot tank 50, when the target water outlet temperature is greater than the hot water temperature in the hot tank 50, entering step S30, and when the target water outlet temperature is less than the hot water temperature in the hot tank 50, entering step S50.
S30, calculating a hot water flow rate calculated value of the hot water control device 10 when the actual water outlet temperature of the heating device reaches the target water outlet temperature in the maximum power state. When the water temperature in the proportional control device 30 is constant, that is, when the water temperature before entering the heating device 40 is constant, the heating power is higher, the water flow rate is higher, and when the heating power is constant, the water temperature in the proportional control device 30 is higher, the water flow rate is higher.
As an exemplary embodiment, when the target outlet water temperature is greater than the hot water temperature in the hot tank 50, the actual outlet water flow rate is highest when the heat only tank 50 is used to outlet water and the heating power is maximum.
In the case of the water outlet from the hot tank 50, the water temperature in the proportional adjustment device 30 is the temperature in the hot tank 50, and thus, when the actual outlet water temperature is stabilized at the target outlet water temperature based on the difference between the hot water temperature in the hot tank 50 and the target temperature at the maximum power of the heating device 40, the theoretical flow rate of the hot water flow rate calculation value of the hot water control device 10 is obtained. Specifically, p=cmΔt, where P is the heating power of the heating device 40, c is the specific heat capacity of water, Δt is the temperature difference between the target outlet water temperature and the hot water temperature in the hot tank 50, m is the hot water flow rate calculation value, and the hot water flow rate calculation value is obtained at the time of pmax.
S40, determining a water temperature value and a maximum flow rate in the proportional regulating device based on the hot water flow rate calculation value. When the target water outlet temperature is greater than the hot water temperature in the hot tank 50, the greater the target water outlet temperature is, the smaller the hot water flow rate calculated value is, the closer the target water outlet temperature is to the hot water temperature in the hot tank 50, and the greater the hot water flow rate calculated value is, therefore, when the target water outlet temperature is sufficiently great, the hot water flow rate calculated value is smaller, water can be discharged only through the hot water control device 10, and under the condition that the heating power is maximum, the actual water outlet temperature reaches the target water outlet temperature, at this time, the water temperature value in the proportional adjustment device 30 is the hot water temperature in the hot tank 50, and the hot water control device 10 performs water outlet according to the hot water flow rate calculated value, namely, the maximum flow rate of the proportional adjustment device 30.
As an exemplary embodiment, as the target outlet water temperature approaches the hot water temperature in the hot tank 50, the temperature difference between the target outlet water temperature and the hot water temperature in the hot tank 50 becomes smaller and smaller, and thus, the hot water flow rate calculated value becomes larger until the hot water flow rate calculated value is equal to the maximum hot water flow rate of the hot tank 50, based on p=cm Δt, with the heating power maintained to be maximum. Under the working condition of the target water outlet temperature, the water outlet is performed at the maximum hot water flow rate by only starting the hot water control device 10, and the heating power is maximum. If the target outlet water temperature is lower than the target outlet water temperature, the calculated hot water flow rate will be greater than the maximum hot water flow rate of the hot tank 50, and the water temperature in the proportional adjustment device 30 can be reduced by adding cold water to find the maximum flow rate, i.e. the water temperature and the maximum flow rate in the proportional adjustment device 30 are determined based on the hot water flow rate calculation. The hot water can be discharged only, namely, the water temperature value in the proportion adjusting device 30 is the temperature of the hot water in the hot tank 50, and the hot water control device 10 can be controlled to discharge water according to the maximum hot water flow rate.
S50, calculating the intersection proportion of cold water and hot water in the proportion adjusting device. As an exemplary embodiment, when the target outlet water temperature is less than the hot water temperature in the hot tank 50, cold and hot junction outlet water may be performed, and the target outlet water temperature may be obtained without heating.
By way of example, the cold water temperature is taken and may be room temperature, for example, 25 ℃, or may be another temperature, for example, 20 ℃,30 ℃, or the like.
In a state where the heating device 40 is stopped from heating, a cold water flow rate and a cold water flow rate when the actual water outlet temperature reaches the target water outlet temperature are calculated from the hot water temperature and the cold water temperatureThe ratio of the hot water flow rate. Exemplary, according to S Cold water +S Heat of the body ＝S Intersection with each other S and S Cold water ×T Cold water +S Heat of the body ×T Heat of the body ＝S Intersection with each other ×T Intersection with each other The method comprises the steps of carrying out a first treatment on the surface of the Obtaining S Cold water ：S Heat of the body ＝(T Heat of the body -T Intersection with each other )：(T Intersection with each other -T Cold water ) The method comprises the steps of carrying out a first treatment on the surface of the Wherein S is Cold water Is the flow rate of cold water, S Heat of the body Is the flow rate of hot water, S Intersection with each other To meet the flow rate, T Cold water Is the temperature of cold water, T Heat of the body At the temperature of hot water, T Intersection with each other Is the junction temperature.
S60, adjusting the hot water control device to the maximum hot water flow rate or adjusting the cold water control device to the maximum cold water flow rate according to the proportion interval where the intersection proportion is located. In the present embodiment, the maximum cold water flow rate of the cold water control device 20 may be 1200ml/min, and the maximum hot water flow rate of the hot water control device 10 may be 2000ml/min. Of course, other nominal flow rates are also applicable in this embodiment, for example, the maximum cold water flow rate may be 1500ml/min and the maximum hot water flow rate may be 1800ml/min; the maximum cold water flow rate may be 2000ml/min, the maximum hot water flow rate may be 1500ml/min, etc.
The water is discharged according to the calculated ratio of cold water to hot water, in order to adjust the actual water outlet flow rate to the maximum, the ratio of the cold water control device 20 or the hot water control device 10 can be adjusted to the maximum, and then the flow rate of the other control device is adjusted to match the value to calculate the ratio of cold water to hot water, so as to obtain the maximum actual water outlet flow rate.
In the present application, when the target outlet water temperature is greater than the hot water temperature in the hot tank 50, the calculated hot water flow rate of the hot water control device 10 when the actual outlet water temperature of the heating device 40 reaches the target outlet water temperature in the maximum power state is calculated, and as the target outlet water temperature approaches the hot water temperature in the hot tank 50, the temperature difference between the target outlet water temperature and the hot water temperature in the hot tank 50 is smaller and smaller, and based on p=cm Δt, under the condition that the heating power is kept to be maximum, the calculated hot water flow rate is larger and larger, if the calculated hot water flow rate does not reach the maximum hot water flow rate, the hot water flow rate is used, and if the calculated hot water flow rate is greater than the maximum hot water flow rate, the maximum hot water flow rate or the cold and hot water outlet can be selected to be carried out in the maximum hot water flow rate and the cold and hot water outlet flow rate, so as to achieve the working condition of the maximum flow rate outlet water under the condition that the target outlet water temperature is satisfied. When the target water outlet temperature is smaller than the hot water temperature in the hot tank 50, water is discharged according to the calculated ratio of cold water to hot water, in order to adjust the actual water outlet flow rate to the maximum, the ratio of the cold water control device 20 or the hot water control device 10 can be adjusted to the maximum, and then the flow rate of the other control device is adjusted to match the value to calculate the ratio of cold water to hot water, so as to obtain the maximum actual water outlet flow rate. Therefore, the maximum flow rate corresponding to the target water outlet temperature can be selected for water outlet at any target water outlet temperature, and the user experience can be greatly improved.
In this embodiment, the control device with a relatively large flow rate may be adjusted to the maximum, so that the flow rate of the other control device is matched and calculated to obtain the ratio of cold water to hot water.
For example, when the proportion of cold water is large, it may be indicated that more cold water is needed and the target outlet water temperature is too low, and on the premise that the heating device 40 is not needed to work, the cold water control device 20 is required to reach the maximum flow rate to meet the target temperature, so that the proportion of cold water can be adjusted to the maximum, and then the flow rate of hot water is adjusted, so that the junction water temperature is stabilized at the target water temperature, and the actual outlet water flow rate obtained at the moment is the maximum.
When the proportion of hot water is larger, more hot water is needed, the proportion of hot water can be adjusted to the maximum for the maximum practical outlet water flow rate, the minimum flow rate of the cold pump is determined according to the maximum flow rate of the hot water control device 10 and the combination target outlet water temperature, on the basis of the minimum flow rate, the maximum flow rate of the hot water control device 10 is kept unchanged, the flow rate of the water control device is increased step by step, meanwhile, the heating device 40 is started, and the heating power of the heating device 40 is adjusted on the premise that the practical outlet water temperature is equal to the target outlet water temperature until the cold water flow rate reaches the maximum or the heating power is increased to the maximum. The obtained actual water outlet flow rate is the largest at the current target water outlet temperature.
Illustratively, determining whether the intersection ratio is greater than a ratio of the maximum cold water flow rate to the maximum hot water flow rate; when the intersection ratio is greater than the ratio of the maximum cold water flow rate to the maximum hot water flow rate, modulating the cold water control device 20 to the maximum cold water flow rate, and increasing the hot water flow rate of the hot water control device 10 until the target outlet water temperature is reached; when the intersection ratio is smaller than the ratio of the maximum cold water flow rate to the maximum hot water flow rate, the hot water control device 10 is adjusted to the maximum hot water flow rate, and the cold water flow rate of the cold water control device 20 is adjusted based on the target outlet water temperature.
If S Cold water ：S Heat of the body >S Cold max :S Thermal max ；
More cold water is needed, at which point S is set Cold water ＝S Cold max Calculate S Heat of the body ＝S Cold water ×(T Intersection with each other -T Cold water )/(T Heat of the body -T Intersection with each other ) The method comprises the steps of carrying out a first treatment on the surface of the This condition represents the maximum cold water and meets the target temperature, at which time the hot water control device 10 cannot increase the flow rate, which is the maximum outlet water flow rate.
If S Cold water ：S Heat of the body <S Cold max :S Thermal max ；
More water is needed for the hot water, and S is set Heat of the body ＝S The thermal energy of the heat at the temperature of the, calculation S Cold water ＝S Cold water ×(T Heat of the body -T Mixing intersection )/(T Mixing intersection -T Cold water ) The method comprises the steps of carrying out a first treatment on the surface of the This condition represents the maximum hot water and the mix merges to the target temperature where the cold water flow rate may be increased appropriately and the heating power may be increased where the flow rate is maximum when the heating power is increased to a maximum or the cold water flow rate is maximized.
As an exemplary embodiment, when the hot water flow rate calculation value determines the water temperature value and the maximum flow rate in the proportional adjustment device 30, since the hot water flow rate calculation value increases as the target outlet water temperature decreases, after the hot water flow rate calculation value increases to the maximum hot water flow rate, the rated flow rate of the hot water control device 10 has been exceeded, and the outlet water may be selected to be discharged at the maximum hot water flow rate. Therefore, the water outlet of the hot water control device 10 is individually controlled, and the smaller flow rate of the calculated hot water flow rate and the maximum hot water flow rate of the hot water control device 10 is selected as the actual water outlet flow rate.
As an exemplary embodiment, when the calculated increase in the flow rate of the hot water is greater than the maximum flow rate of the hot water, the water is discharged at the maximum flow rate of the hot water is selected, the heating power of the heating means 40 is controlled to be reduced.
As another alternative embodiment, since the maximum hot water flow rate is used for water discharge, which may not be the maximum water flow rate corresponding to the current target water discharge temperature, it is also conceivable to turn on the cold water control device 20, reduce the water temperature in the proportional adjustment device 30 while maintaining the maximum heating power, and perform water discharge in a manner of cold and hot junction water.
When the preset condition of the stable intersection water is reached, the intersection flow rate of the intersection water and the maximum hot water flow rate can be compared, and the maximum water flow rate is selected as the actual water flow rate.
As an exemplary embodiment, controlling the cold water control device 20 to be turned on, reducing the water temperature in the proportion adjustment device 30, and performing cold and hot junction water includes: and gradually reducing the intersection water temperature under the state that the actual water outlet temperature is kept equal to the target water outlet temperature by the heating device 40 at the maximum power to obtain an intersection flow rate, and taking the intersection flow rate as the actual water outlet flow rate to carry out water outlet. In the present embodiment, since the calculated hot water flow rate is already greater than the maximum flow rate of the hot water control device 10, the junction water temperature can be gradually reduced so that the junction flow rate gradually decreases from the calculated hot water flow rate to seek the optimal outlet water flow rate.
In the present embodiment, the actual flow rate of the hot water control outlet water may be set to the maximum hot water flow rate, and the flow rate of the cold water control device 20 may be gradually increased by decreasing the junction water temperature.
Alternatively, the hot water flow rate in the hot water control device 10 may be gradually reduced and the cold water flow rate in the cold water device may be gradually increased in a state that the heating device 40 maintains the actual outlet water temperature equal to the target outlet water temperature at the maximum power.
Therefore, in the process of gradually reducing the flow rate of hot water in the hot water control device 10 and gradually increasing the flow rate of cold water in the cold water device, the intersection flow rate is calculated step by step, and the intersection flow rate is compared with the maximum flow rate of hot water step by step, and when the condition of stopping reducing the intersection water temperature is not reached, if the intersection flow rate of cold water and hot water in the proportional adjustment device 30 is smaller than the maximum flow rate of hot water, the hot water control device 10 is independently controlled to output water, and the maximum flow rate of hot water is taken as the actual output water flow rate.
If the condition of stopping lowering the junction water temperature is reached, if the junction flow rate of the cold water and the hot water in the proportional adjustment device 30 is greater than the maximum hot water flow rate, the junction flow rate is taken as the actual outlet water flow rate, and the corresponding maximum outlet water flow rate at the current outlet water temperature can be determined.
As an example of an implementation of the method,
in reducing the junction water temperature, the water outlet flow rates of the cold water control device 20 and the hot water control device 10 often have a steady and linear reasonable flow rate interval, for example, the reasonable flow rate interval of the cold water control device 20 is 25% -100% of the maximum cold water flow rate, and the reasonable flow rate interval of the hot water control device 10 is 15% -100% of the maximum hot water flow rate.
Therefore, in order to ensure the outlet water temperature, in the process of gradually reducing the flow rate of the hot water in the hot water control device 10 and gradually increasing the flow rate of the cold water in the cold water device, it may be determined whether the flow rate of the cold water reaches a preset cold water flow rate interval, and whether the flow rate of the hot water reaches a preset hot water flow rate interval.
If the intersection flow rate of the cold water and the hot water in the proportion adjustment device 30 is greater than the maximum hot water flow rate, and the hot water flow rate reaches a preset hot water flow rate interval, and the cold water flow rate reaches a preset cold water flow rate interval, the intersection flow rate is taken as the actual water outlet flow rate.
