The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The instant water dispenser, the method and the device for controlling the outlet water temperature thereof and the storage medium according to the embodiment of the invention are described below with reference to the accompanying drawings.
At present, due to the limitation of the production process level, parts in the hot water dispenser generally have tolerance, so that certain errors also exist according to factory parameters set by the parts, for example, the rated power tolerance level of a heat pipe is between-10% and + 5%, the water flow speed tolerance of a water pump under the same driving voltage is +/-20%, and the superposition of various errors is considerable, so that the normal use of the hot water dispenser is influenced. Moreover, as the service life of the product is prolonged, the problem of part aging gradually occurs, and further errors are easily further enlarged.
Due to the above-mentioned errors, in the process of controlling the outlet water temperature of the instant water dispenser, the problem of inaccurate temperature control is likely to occur, especially when the instant water dispenser is a water dispenser with strong heating capability or when the voltage fluctuation of the local power grid is large, the outlet water temperature may rise too hard to exceed the target temperature and reach the vicinity of the boiling point, so that a large amount of outlet water is vaporized, and the problems of splashing of the outlet water, unattractive water shape, even water spray, steam spray and the like are caused, or the outlet water temperature cannot reach the target temperature, so that the user requirements cannot be met.
Therefore, the invention controls the flow change of the water pump and the output power change of the instant heating pipe through a software algorithm, firstly determines the set temperature, the inlet water temperature and the actual outlet water temperature of the instant heating water dispenser, when the phenomenon that the outlet water temperature of the instant water dispenser overshoots is determined according to the set temperature and the actual outlet water temperature, determining the downshift power according to the set temperature, the inlet water temperature and the actual outlet water temperature, controlling the reduction of the success rate of the instant water dispenser according to the downshift power, the water outlet flow of the instant heating water dispenser is controlled according to the set temperature and the actual water outlet temperature, so that the water outlet temperature can be controlled by controlling the flow change of the water pump and the output power change of the instant heating pipe, when the outlet water temperature of the instant water dispenser overshoots, the instant water dispenser can be effectively and timely inhibited, the phenomenon that the outlet water of the instant water dispenser is vaporized due to the temperature overshoot to scald a user is avoided, and the use safety of the instant water dispenser and the use experience of the user are improved.
Fig. 1 is a flow chart of a method for controlling the temperature of outlet water of an instant water dispenser according to an embodiment of the invention.
As shown in figure 1, the invention provides an outlet water temperature control method of an instant heating water dispenser, which comprises the following steps:
and S10, determining the set temperature, the inlet water temperature and the actual outlet water temperature of the instant water dispenser.
Specifically, the schematic diagram of the instant water dispenser according to the embodiment of the present invention is shown in fig. 2 or fig. 3, where fig. 2 and fig. 3 only show some parts of the instant water dispenser and are labeled, and the other parts not shown and not labeled in this embodiment do not specifically limit the same.
The instant heating water dispenser in this embodiment may include a water pump 113, an instant heating pipe 115, a water outlet 111, a water inlet 112, and an outlet water temperature detection device 114. Wherein, the water inlet 112 is connected with a water pump 113, and the water pump 113 can guide the drinking water to the water inlet 112, the water in the water inlet 112 can be heated by the heat pipe 115 and then flows out of the water outlet 111. A water inlet temperature detecting device (not shown in the figure) is disposed on the water inlet 112, and it should be noted that the water inlet temperature detecting device may be a Negative Temperature Coefficient (NTC) water inlet, and the water inlet temperature T of the instant water dispenser can be determined by the NTC water inletInflow waterThe resistance value of the water inlet pipe can be reduced along with the rise of the temperature, a relation curve exists between the temperature and the resistance value, and the corresponding temperature, namely the water inlet temperature, can be obtained through the detection of the resistance value or the detection of parameters related to the resistance value. Similarly, the outlet water temperature detecting device 114 in the embodiment of the present invention may also be an outlet water NTC for detecting the actual outlet water temperature T of the instant water dispenserDischarging waterAnd, the tube temperature NTC may be disposed on the heat pipe 115 to detect the current temperature of the heat pipe. In addition, the set temperature Ts in this embodiment may be specifically set according to the actual needs of the user, for example, if the user needs boiling water, the set temperature Ts may be set to 100 degrees celsius, and if the user needs to drink warm water at present, the set temperature Ts may be set to 50 degrees celsius or 60 degrees celsius. That is, the set temperature Ts in this embodiment is directly accessible in the program memory in the instant water dispenser.
Therefore, in this embodiment, the inlet water temperature T may be obtained by using the inlet water NTCInflow waterObtaining the actual outlet water temperature T by using the outlet water NTCDischarging waterAnd acquiring the set temperature Ts by using an acquisition instruction in the chip. It should be noted that the embodiment of the present invention is described only by way of specific examples of obtaining the inlet water temperature, the actual outlet water temperature, and the set temperature, and the way of obtaining the temperature is not limited to the way of determining the inlet water temperature, the actual outlet water temperature, and the set temperature in the present application.
And S20, when the phenomenon that the outlet water temperature of the instant water dispenser overshoots is determined according to the set temperature and the actual outlet water temperature, determining the downshift power according to the set temperature, the inlet water temperature and the actual outlet water temperature, and controlling the outlet water flow of the instant water dispenser according to the set temperature and the actual outlet water temperature after the success rate of the instant water dispenser is controlled to be reduced according to the downshift power.
Generally speaking, an instant heating water dispenser is heated through an instant heating pipe, measures for influencing the water outlet temperature are taken along with heating, the water outlet temperature and the water outlet quantity are set according to needs, the flow change of a water pump and the output power change of the instant heating pipe are controlled by software, and the change of the water outlet temperature is controlled by means of heating and adjusting the water flow speed through a temperature control module and a volume calculation module in the instant heating water dispenser, so that the water outlet requirement of a user is met. In the process of controlling the outlet water temperature, overshoot is a serious control failure, particularly when the set temperature is more than 90 ℃, the overshoot of the outlet water temperature is close to the boiling point, and in serious conditions, the problems that the outlet water is boiled and vaporized and is sprayed out from a water outlet nozzle to splash and the like can occur, so that people can be scalded. Furthermore, as shown in fig. 4, in the related art, the heating temperature is generally suppressed first, and then the heating power is restored to the original heating power after the temperature is decreased, in this case, if the overshoot suppression force is too large, the suppressed rise back may cause secondary overshoot under the action of the normal temperature control algorithm, or the temperature may fluctuate all the time and cannot be stabilized. Therefore, the present embodiment controls both the power of the heat pipe and the flow rate of the water pump, and adopts a strategy of rapid fall and slow rise, so as to avoid the phenomenon of the secondary overshoot described above.
Specifically, after the set temperature, the water inlet temperature and the real-time water outlet temperature of the instant water dispenser are determined, whether the water outlet temperature of the instant water dispenser overshoots or not can be determined according to the set temperature and the actual water outlet temperature, for example, when the actual water outlet temperature is greater than 95 degrees celsius or 98 degrees celsius and the set temperature is only 90 degrees celsius, the water outlet temperature of the instant water dispenser overshoots can be determined. When the phenomenon that the outlet water temperature of the instant water dispenser overshoots is determined, the downshift power can be further determined according to the set temperature, the inlet water temperature and the actual outlet water temperature, then the power reduction control is performed on the instant heat pipe in the instant water dispenser according to the downshift power, and after the power reduction of the instant water dispenser is completed, the outlet water flow of the instant water dispenser is controlled according to the set temperature and the actual outlet water temperature, so that the actual outlet water temperature slowly rises.
Referring to fig. 5, in this embodiment, the actual outlet water temperature is suddenly decreased by controlling the power output of the heat pipe, and then the actual outlet water temperature is slowly increased by controlling the flow rate of the water pump to decrease, so that the temperature control system does not have too much energy oscillation, and the actual outlet water temperature is ensured to be in a stable state and does not have a secondary overshoot phenomenon.
It should be noted that, in fig. 4 and 5, the abscissa is time, and the ordinate is a set of setting values, by which the temperature and the power can be represented simultaneously, for example, by dividing the power by a certain value, or by multiplying the temperature by a certain value, the temperature and the power can be represented by a same set of numbers, thereby improving readability of the coordinate view and facilitating comparison.
In some embodiments of the present invention, the phenomenon of the overshoot of the outlet water temperature of the instant water dispenser is determined according to the set temperature and the actual outlet water temperature, as shown in fig. 6, the method includes the following steps:
s601, when the outlet water temperature is higher than the set temperature, the temperature difference between the actual outlet water temperature and the set temperature is determined.
Specifically, in this embodiment, the detection information may be fed back to the control unit according to the real-time detection of the water temperature near the water outlet by the outlet water temperature sensor in the water outlet device. The control unit has a control function, for example, the control unit can be realized by a single chip microcomputer, and the outlet water temperature sensor is connected with one of the I/0 (Input/Output) interfaces of the single chip microcomputer, so that the single chip microcomputer can acquire outlet water temperature information from the outlet water temperature sensor. After the temperature sensor detects the outlet water temperature, the outlet water temperature can be compared with the set temperature, and when the outlet water temperature is higher than the set temperature, the temperature difference between the actual outlet water temperature and the set temperature is calculated.
S602, when the set temperature is greater than or equal to a first preset temperature and the temperature difference is greater than or equal to a first preset temperature threshold value, the phenomenon that the outlet water temperature of the instant heating water dispenser overshoots is determined.
It should be noted that, when the instant water dispenser is an instant water dispenser with extremely strong heating capability, that is, the heating speed is very fast, or when the voltage fluctuation of the local power grid is large, the overshoot phenomenon is very easily generated. Particularly, when a user uses the boiling water function, the set temperature is very high, the water outlet temperature may rise too violently to exceed the target temperature and reach the vicinity of the boiling point, so that a large amount of water is vaporized, and the problems of splashing of the water, unattractive water shape, even scalding of the user due to water spraying and steam spraying are caused. Therefore, in some embodiments, the first predetermined temperature may be set to 95 ℃ and the first predetermined temperature threshold may be set to 3 ℃.
For example, if the set temperature is 96 ℃, and the temperature difference between the actual outlet water temperature and the set temperature is 4 ℃, then the actual outlet water temperature is 100 ℃, and the boiling point under the standard atmospheric pressure is reached, so that the outlet water is likely to be vaporized, and the user experience is likely to be affected.
In some embodiments of the present invention, determining the downshift power based on the set temperature, the inlet water temperature and the actual outlet water temperature, as shown in fig. 7, includes:
s701, determining a first temperature difference between a set temperature and an actual water outlet temperature, and determining a second temperature difference between a water temperature and a water inlet temperature.
It should be noted that, a temperature sensor is arranged near the water outlet for detecting the actual outlet water temperature T of the water outlet in real timeDischarging waterAnd a temperature sensor is arranged near the water inlet for detecting the water inlet temperature T of the water inlet in real timeInflow waterThen the set temperature Ts and the actual outlet water temperature T are comparedDischarging waterPerforming difference to obtain a first temperature, and comparing the actual outlet water temperature TDischarging waterAnd the temperature T of the inlet waterInflow waterA difference is made to obtain a second difference value. It should be noted that, the first difference and the second difference may be directly calculated in the processor, for example, a single chip is used to obtain the set temperature Ts and the outlet water temperature TDischarging waterAnd recording the difference as a first temperature difference to obtainTemperature T of waterDischarging waterWith the temperature T of the inlet waterInflow waterAnd is recorded as the second temperature difference.
S702, acquiring the current heating power of the instant heating water dispenser, and determining the downshift power according to the current heating power, the first temperature difference and the second temperature difference.
In some embodiments, the downshift power is calculated according to the following equation:
Figure BDA0003624992810000081
wherein PowerLimt is downshift power, Ts is set temperature, TDischarging waterIs the actual outlet water temperature, TInflow waterAnd the water inlet temperature is obtained, the Power is the current heating Power, and k is a preset coefficient.
In particular, according to the formula in the above embodiment
Figure BDA0003624992810000082
That is, the heat pipe performs power reduction operation, for example, when the current set temperature is 95 degrees, the outlet water temperature is 98 degrees, the execution power is 2000W, k is 1.2, and the inlet water temperature is 25 degrees, the following formula is substituted to obtain:
Figure BDA0003624992810000083
Figure BDA0003624992810000084
where k is an empirical coefficient, meaning that a greater or lesser degree of inhibition is artificially given. If k is 1.2, the inhibition strength is 1.2 times of the theoretical value.
Further, when the power is reduced, two options are available, wherein the first option is to keep the current power unchanged, and perform PID (proportional-derivative-Integral) control on the driving voltage of the water pump to indirectly control the outlet water temperature to be stabilized to reach the vicinity of the target temperature by controlling the outlet water flow. The second one is that nW (such as 20W per 2 seconds) of every m seconds is slowly recovered to the original power to exert the whole heating capacity of the water dispenser, so that the best water using experience is realized, and meanwhile, the outlet water temperature can be relatively stable due to the fact that the power rises relatively slowly, and secondary overshoot or repeated fluctuation cannot be stable.
Two ways of the downshift power control, namely, the manner of reducing the success rate of the hot water dispenser, are described in detail below, and specifically, in an embodiment of the present invention, as shown in fig. 8, the method includes the following steps:
s801, controlling the completion rate of the instant water dispenser to be reduced according to the downshift power. S802, controlling the instant heating water dispenser to keep the current heating power unchanged. And S803, controlling the water outlet flow of the instant water dispenser according to the set temperature and the actual water outlet temperature.
Specifically, after the completion rate of the instant water dispenser is controlled according to the downshift power, in order to avoid the excessive overshoot suppression, the rise-back after the suppression may cause secondary overshoot under the action of a normal temperature control algorithm, or the temperature is always fluctuated to cause the temperature not to be stabilized, the instant water dispenser is controlled to keep the current heating power unchanged, the PID control is performed on the driving voltage for controlling the water outlet of the water pump, so that the water outlet quantity of the instant water dispenser is controlled, and the water outlet temperature is controlled to slowly and stably reach the vicinity of the set temperature. More specifically, when overshoot occurs (i.e., the outlet water temperature is higher than the set temperature), the water pump is driven to output a larger voltage (corresponding to a larger flow rate) to lower the outlet water temperature, so as to suppress overshoot, and the higher the outlet water temperature, the larger the corresponding driving voltage, i.e., the larger the flow rate, i.e., the stronger the suppression strength.
In another embodiment of the present invention, as shown in fig. 9, the method comprises the steps of:
and S901, controlling the completion rate of the instant water dispenser to be reduced according to the downshift power. And S902, controlling the heating power of the instant water dispenser to slowly recover to the initial heating power according to a preset step length. And S903, controlling the water outlet flow of the instant water dispenser according to the set temperature and the actual water outlet temperature.
Specifically, after the completion rate of the instant water dispenser is controlled according to the downshift power, in order to avoid overlarge overshoot suppression, the rise-back after suppression may cause secondary overshoot under the action of a normal temperature control algorithm, or the temperature fluctuates all the time to cause the temperature not to be stable, the heating power of the instant water dispenser is controlled according to a preset step length to slowly recover to the initial heating power, meanwhile, the PID control is carried out on the driving voltage for controlling the water outlet of the water pump, so that the water outlet quantity of the instant water dispenser is controlled, and the water outlet temperature is controlled to slowly and stably reach the vicinity of the set temperature.
It should be noted that the preset step size in this embodiment is to increase the preset power every preset time, such as 20 watts every 2 seconds as indicated in the above example.
In an embodiment of the present invention, as shown in fig. 10, the method for controlling the outlet flow of the instant water dispenser according to the set temperature and the actual outlet temperature includes the following steps:
and S1001, determining the temperature difference between the actual outlet water temperature and the set temperature.
S1002, determining the driving voltage of the water pump in the instant heating water dispenser according to the temperature difference.
And S1003, controlling the flow rate of the water pump according to the driving voltage so as to adjust the water outlet flow of the instant heating water dispenser.
Specifically, in this embodiment, after the sudden drop of the outlet water temperature is completed by adjusting the output power of the instant heating pipe, the gradual rise of the outlet water temperature can be completed by adjusting the outlet water flow of the instant heating water dispenser. More specifically, in this embodiment, the drive voltage of the water pump may be calculated according to the following formula:
Figure BDA0003624992810000091
wherein u is the driving voltage of the water pump, and the larger u is, the larger the output value is, and the larger the flow rate of the water pump is; the smaller u, the smaller the pump flow rate. E is the temperature difference between the actual outlet water temperature and the set temperature at the current moment, namely E is TDischarging water-TsAnd E 'is the temperature difference between the actual outlet water temperature and the set temperature at the last moment, for example, each certain time interval is one moment, the invention takes 100ms as one moment, the moment of just starting to discharge water is defined as 0 moment, and E' means the E value before 100 ms. n is the number of times of updating the instant water dispenser from the water outlet time to the current time, for example, every 100ms from the water outlet time of the instant water dispenser to the current timeIt is accumulated once. Kp、Ki、KdThree constant coefficients in the PID algorithm, obtained for laboratory debugging. In the present invention, Kp、Ki、KdThe three values are 20/0.4/200 respectively, and
Figure BDA0003624992810000092
the total value of the E value accumulation from the water outlet time of the instant water dispenser to the current time is represented.
Therefore, the water pump in this embodiment may calculate the current water pump driving voltage according to a formula in real time every 100ms, so as to control the current water pump flow, and output the driving voltage to the water pump to perform an actual operation.
Summarizing, when the overshoot phenomenon of the water temperature is determined, the current heating power is rapidly reduced, then the instant heating water dispenser can be controlled through an algorithm to keep the current heating power unchanged or control the heating power to be slowly increased, the water outlet flow of the instant heating water dispenser can be controlled according to the set temperature and the actual water outlet temperature, and the water outlet flow speed is reduced by reducing the driving voltage of the water pump. Meanwhile, the output power of the heat pipe and the water outlet flow of the water pump are controlled, so that the water outlet temperature is slowly close to the target temperature, and the phenomenon that the water outlet temperature overshoots to scald a user is prevented.
In conclusion, the outlet water temperature control method of the instant water dispenser can control the outlet water temperature by controlling the flow change of the water pump and the output power change of the instant heat pipe, so that when the outlet water temperature of the instant water dispenser overshoots, the instant water dispenser can be effectively inhibited, the phenomenon that a user is scalded due to the vaporization of the outlet water of the instant water dispenser caused by the overshoot of the temperature is avoided, and the use safety and the use experience of the user of the instant water dispenser are improved.
