Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. 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.
An instant water dispenser, a heating control method and device thereof, and a storage medium according to embodiments of the present invention are described below with reference to the accompanying drawings.
Due to the fact that the tolerance of the production process level cannot be completely unified, the voltage of a power grid is unstable and the like, even if the instant heating pipe is controlled by using unified rated power in the using process of the instant heating water dispenser, a certain error exists in the actual heating power, and at the moment, if the actual heating power is too large in difference, the situation that the temperature rise is too fast and even overshooting is out of control easily occurs, or the situation that the temperature rise is too slow and the user requirements cannot be met easily occurs.
Therefore, the invention provides a heating control method of an instant heating water dispenser, which is characterized in that the corresponding heating power is calculated according to the actual temperature rise and the actual flow rate, then the heating power is utilized to carry out heating control on an instant heating pipe, further the outlet water temperature of the instant heating water dispenser can be accurately controlled, the temperature overshoot or over-low is prevented, and the use safety and the user experience of the instant heating water dispenser are effectively improved.
Fig. 1 is a flow chart of a heating control method of an instant heating water dispenser according to an embodiment of the invention.
As shown in fig. 1, the invention provides a heating control method of an instant heating water dispenser, which comprises the following steps:
and S10, detecting the water inlet temperature and the water outlet temperature of the instant heating water dispenser and detecting the actual flow rate of the instant heating water dispenser.
Specifically, a 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 zero devices in the instant water dispenser and are labeled, and the other zero devices that are not shown and are 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 the water pump 113, the water pump 113 can guide the drinking water to the water inlet 112, and the water in the water inlet 112 can be heated by the heat pipe 115 and then flows out from the water outlet 111. The water inlet 112 is provided with a water inlet temperature detecting device (not shown in the figure), it should be noted that the water inlet temperature detecting device may be a Negative Temperature Coefficient (NTC) water inlet, the water inlet temperature of the instant heating water dispenser can be confirmed through the NTC water inlet, the resistance value of the instant heating water dispenser becomes smaller along with the rise of the temperature, and 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 the parameter associated with 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 outlet water temperature of the instant water dispenser, and in some embodiments, a pipe temperature NTC may also be disposed on the instant pipe 115 for detecting the current temperature of the instant pipe.
In this embodiment, a flow meter (not shown in the figure) may be disposed on the water outlet waterway near the water outlet 111 for connecting the water inlet and outlet waterway of the instant heating water dispenser, when the user uses water, the water flowing out of the instant heating water dispenser needs to pass through the flow meter, the flow meter may count the real-time water outlet flow rate, i.e. the actual flow rate of the user in real time,
therefore, in this embodiment, the inlet water temperature may be obtained by using the inlet water NTC, the outlet water temperature may be obtained by using the outlet water NTC, and the actual flow rate may be obtained by using the flow meter. It should be noted that, the embodiment of the present invention is described only by way of specific acquiring manners of the inlet water temperature, the outlet water temperature, and the actual flow rate, and the acquiring manners are not limited in this application.
S20, when the temperature rise of the instant heating water dispenser is determined to be stable according to the water outlet temperature, the current temperature rise is determined according to the water inlet temperature and the current water outlet temperature, and the current heating power of the instant heating water dispenser is determined according to the current temperature rise and the actual flow rate.
Specifically, since the outlet water temperature of the instant water dispenser is unstable when the instant water dispenser is initially discharging water, and if the outlet water temperature is taken as a judgment basis to calculate the temperature rise, the temperature rise is obviously incorrect, the embodiment needs to determine whether the temperature rise is stable according to the outlet water temperature, and since the inlet water temperature is generally stable, after the outlet water temperature is stable, the temperature rise can be determined to be stable according to the stable outlet water temperature and the inlet water temperature.
It can be understood that there are many ways to determine the temperature rise of the instant water dispenser to be stable according to the outlet water temperature in this embodiment, for example, a preset temperature value may be set, and the preset temperature value may be different from a target temperature value set by a user by a set value, when the outlet water temperature exceeds the preset temperature value, it may be determined that the temperature rise is already stable, for example, the user sets the target temperature to be 80 degrees celsius, and when the outlet water temperature exceeds 75 degrees celsius, it is determined that the temperature rise of the instant water dispenser is already stable. And then determining the current temperature rise according to the water inlet temperature and the current water outlet temperature, for example, if the current water outlet temperature is 75 degrees celsius and the water inlet temperature is 25 degrees celsius, the current temperature rise can be determined to be 75-25 degrees celsius to 50 degrees celsius.
Because the heating power of the instant heating water dispenser can influence the temperature rise and the flow rate, after the current temperature rise is determined, the current heating power of the instant heating water dispenser can be further determined according to the current temperature rise and the actual flow rate.
And S30, controlling an instant heating pipe of the instant heating water dispenser to heat according to the current heating power.
After the current heating power of the instant water dispenser is obtained through calculation, the instant water dispenser can be controlled according to the current heating power, so that the instant pipe of the instant water dispenser can control the instant pipe to perform heating work according to the current heating power, or the driving voltage of a water pump in the instant water dispenser is further calculated according to the current heating power, and then the instant water dispenser is controlled to discharge water through the driving voltage of the water pump.
In some embodiments of the present invention, as shown in fig. 4, determining that the temperature of the instant water dispenser is stable according to the outlet water temperature includes:
s401, acquiring the target temperature of the instant heating water dispenser. S402, when the difference value between the outlet water temperature and the target temperature is less than or equal to a preset temperature threshold value and lasts for a preset time, determining that the temperature rise of the instant heating water dispenser is stable.
Specifically, in the step of determining that the temperature of the instant water dispenser is stable, a target temperature of the instant water dispenser, for example, 95 degrees celsius, may be obtained first, and then when a difference between the outlet water temperature and the target temperature is less than or equal to a preset temperature threshold and continues for a preset time, it may be determined that the temperature of the instant water dispenser is stable. After the target temperature is determined, namely the temperature of the hot water dispenser rises faster in the process of starting heating, and becomes slower after gradually approaching the target temperature, when the temperature difference between the target temperature and the outlet water temperature is continuously within the preset temperature threshold, the temperature rise can be determined to be stable. The preset time and the preset temperature threshold can be determined according to parameters such as the power of the instant water dispenser and the like, and also can be determined according to a large amount of experimental data, the preset time can be determined to be 6 seconds, and the preset temperature threshold can be +/-3 ℃.
That is, when the difference between the outlet water temperature and the target temperature is within the range of ± 3 degrees celsius and lasts for 6 seconds, it can be determined that the temperature rise of the instant water dispenser is in a stable state at present.
It should be noted that, in this embodiment, after the temperature rise is stable, the target flow rate within the preset time may be recorded, and specifically, the average processing may be performed on the outlet flow rate recorded within the preset time to obtain the target flow rate.
It should be noted that, in this embodiment, as shown in fig. 5, after obtaining the target temperature of the instant water dispenser, the following steps are further included:
s501, determining the target flow rate and the target power of the instant water dispenser according to the target temperature.
Firstly, it should be noted that, in the factory setting of the instant water dispenser, the corresponding relationship between the target temperature and the target flow rate and the target power is set, that is, after the target temperature is determined, the target flow rate and the target power required by the instant water dispenser can be determined according to the target temperature. For example, in one specific embodiment, after the target temperature is determined to be 95 degrees celsius, the target flow rate of the instant hot water dispenser may be determined to be 200 milliliters per minute and the target power may be 1500 watts by a look-up table or by calculation.
S502, controlling the water outlet flow of the instant heating water dispenser according to the target flow rate, and controlling the instant heating pipe to heat according to the target power.
After the target flow rate and the target power are determined, the water outlet flow of the instant heating water dispenser can be controlled according to the target flow rate, and the instant heating pipe is heated according to the target power, so that the water outlet temperature of the instant heating water dispenser reaches the target temperature. The embodiment is that when the instant water dispenser works at a target flow rate and a target power, the actual flow rate and the actual temperature rise of the instant water dispenser are determined when the temperature of the outlet water is stable, then the current heating power is determined according to the actual flow rate and the actual temperature rise, and then the heating water dispenser is controlled according to the current heating power, so that the phenomena of temperature overshoot and the like when the instant water dispenser works by uniformly adopting the target power due to different working environments and the like are prevented.
In some embodiments of the invention, the current heating power is calculated according to the following formula: p ═ c × ρ × v × Δ T, where P is the current heating power, c is the specific heat capacity of water, ρ is the density of water, v is the actual flow rate, and Δ T is the current temperature rise.
Specifically, after the actual flow rate and the current temperature rise of the instant heating water dispenser are determined, the current instant heating power of the instant heating water dispenser can be directly determined according to the actual flow rate and the current temperature rise, and then the instant heating water dispenser is controlled according to the current instant heating power.
The current heating power formula is derived as follows, in which the time T can be determined by dividing the actual flow by the actual flow rate, i.e. the time T
Wherein V is the actual total flow rate, V is the actual flow rate, and since the outlet water mass m ═ ρ × V, the equivalent formula of T and m is substituted into the formula Pt ═ c × m × Δ T and simplified, the formula P ═ c × ρ V Δ T can be obtained, and therefore, after the actual flow rate and the current temperature rise are obtained, a value corresponding to the actual flow rate and the current temperature rise can be determinedCorresponding current heating power.
In summary, according to the embodiment of the invention, firstly, the target flow rate and the target power of the instant water dispenser are determined according to the target temperature according to the preset corresponding relationship, the instant water dispenser is controlled according to the target flow rate and the target power, the actual flow rate and the actual temperature rise of the instant water dispenser are obtained, then, the current heating power of the instant pipe is determined according to the actual flow rate and the actual temperature rise, and the instant water dispenser can be controlled according to the current heating power after the corresponding flow rate and the corresponding temperature rise are obtained subsequently, so that the problem that the target power in the instant water dispenser cannot meet the requirements of the instant water dispenser under all working conditions is solved, and the user experience is improved.
In summary, the heating control method of the instant water dispenser of the embodiment of the invention can determine the heating power currently required by the instant water dispenser, so as to accurately control the outlet water temperature of the instant water dispenser, prevent temperature overshoot or over-low, and effectively improve the use safety and user experience of the instant water dispenser.
