and S1, receiving the bathing temperature and the bathing time set by the user.
In the embodiment of the invention, the user can set the bathing temperature and the bathing time through the function keys arranged in the user interaction interface of the water heater, or the bathing temperature and the bathing time are set through the remote controller. In other embodiments of the invention, the user can also establish connection between the mobile terminal and the water heater, and bath temperature and bath time are set through the mobile terminal, so that the user does not need to enter a room for installing the water heater, and the use experience of the user is improved.

And S3, determining the water flow corresponding to the user according to the historical record. Wherein, the water flow that the user corresponds can be the play water flow in the water heater inner bag.
Specifically, after the water heater receives the bathing temperature and the bathing time set by the user, the historical records of multiple days can be called from the storage space of the water heater, and the historical records of the multiple days are analyzed to obtain the water flow corresponding to the user, wherein the water flow can be the user common water flow recorded in the historical records of the multiple days.
It should be noted that the storage space described in the above embodiments is not limited to a physical-based storage space, such as a hard disk, and the storage space may also be a storage space (cloud storage space) of a network hard disk connected to a water heater.
And S4, calculating the heating temperature corresponding to the heating component in the water heater in the iteration time by adopting a preset temperature iteration method according to the water flow corresponding to the user and the preset heating temperature. The preset heating temperature may be calibrated according to time, for example, the preset heating temperature may be 40 ℃.
It should be noted that the preset heating temperature described in the above embodiment may be a default heating temperature set by a factory of the water heater, or may be a default heating temperature set by a user.
In one embodiment of the invention, the heating assembly comprises a vertically layered array of energy blocks in the liner, as illustrated in fig. 2, wherein the array of energy blocks comprises N x M energy blocks. Wherein both N and M can be positive integers.
For example, as shown in fig. 2, the cylindrical liner space of the water heater is divided into N-5 layers, and each layer includes M-3 energy blocks. It can be understood that, theoretically, if the numerical values of N and M are larger, the mathematical calculation value is closer to the true value, but if the layering in the inner container of the water heater and the number of energy blocks of each layer are increased, the difficulty geometric grade of the algorithm is increased, so that the calculation cannot be realized by a single chip microcomputer system in practical application, and the system cost and the applicability are greatly increased.
In one embodiment of the present invention, the above-mentioned preset temperature iteration method satisfies the following formula (1):
wherein,the temperature of the (i, j) th energy block at the moment t +1, i is the number of layers from bottom to top, i is less than or equal to N, j is an energy block from left to right, j is less than or equal to M,is the temperature, v, of the (i, j) th energy block at time tijFor the heating rate of the heating tube,.

and S10, updating the current time t +1, and acquiring the temperature of the (i, j) th energy block at the time t + 1.
And S20, judging whether the temperature of the (i, j) th energy block at the time of t +1 is less than or equal to the bathing temperature.
And S30, if the temperature of the (i, j) th energy block at the time t +1 is less than or equal to the bathing temperature, taking the time t +1 as the iteration time.
And S40, judging whether the iteration time is longer than the bathing time.
And S50, if the iteration time is greater than or equal to the bathing time, setting the preset heating temperature as the initial heating temperature of the water heater.
S60, if the iteration time is less than the bathing time, increasing the preset heating temperature by the preset threshold temperature and returning to the step S10. The preset threshold temperature may be calibrated based on actual conditions, for example, the preset threshold temperature may be 5 ℃.
S70, if the temperature of the (i, j) th energy block at the time t +1 is higher than the bathing temperature, returning to the step S10.
For example, if the user sets a bathing time of 10 minutes and a bathing temperature of 40 ℃, the obtained user common water flow Q and the preset heating temperature of 40 ℃ can be substituted into the formula (1) for iteration. If iterate toAnd if the iteration time t +1 is less than 10 minutes, the preset heating temperature can be set to be 45 ℃ (namely, the preset heating temperature is increased by the preset threshold temperature), the formula (1) is substituted again for iteration, and the analogy is carried out until the iteration time t +1 is more than or equal to 10 minutes.
In summary, the control method of the water heater provided by the embodiment of the invention can automatically determine the initial heating temperature of the water heater according to the requirements of the user to satisfy the bathing of the user, thereby avoiding the problem that the energy consumption of the water heater is too high due to the highest setting of the initial heating temperature of the water heater by the user, and improving the user experience.
In addition, after the initial heating temperature is determined, the water heater can be controlled to inject water into the water heater to heat according to the initial heating temperature so as to meet the bathing requirement of a user.
To make the present invention more apparent to those skilled in the art, fig. 4 is a flowchart of a control method of a water heater according to one embodiment of the present invention. As shown in fig. 4, the control method of the water heater may include the steps of:
s101, receiving bathing temperature (for example, 40 ℃) and bathing time (for example, 10 minutes) set by a user.
S102, acquiring a history record of the water heater used by a user, and determining water flow corresponding to the user according to the history record.
S103, a preset heating temperature (e.g., 40 ℃) is read.
And S104, substituting the corresponding parameters into a temperature iteration formula (for example, the formula (1) above) for iteration.
S105, judging whether the temperature of the (i, j) th energy block at the time of t +1 is less than or equal to the bathing temperature. If yes, go to step S106; if not, return to step S104.
And S106, judging whether the iteration time (t +1 moment) is greater than the bathing time. If yes, go to step S107; if not, step S105 is performed.
And S107, setting the preset heating temperature as the initial heating temperature of the water heater.
And S108, increasing the preset heating temperature by a preset threshold temperature (for example, 5 ℃).
To sum up, the control method of the water heater according to the embodiment of the present invention first receives the bathing temperature and the bathing time set by the user, then obtains the history record of the water heater used by the user, determines the water flow rate corresponding to the user according to the history record, then calculates the heating temperature corresponding to the heating component in the water heater during the iteration time by using the preset temperature iteration method according to the water flow rate corresponding to the user and the preset heating temperature, and finally determines the initial heating temperature of the water heater according to the heating temperature, the iteration time, the preset heating temperature, the bathing temperature and the bathing time corresponding to the iteration time. Therefore, the method can automatically determine the initial heating temperature of the water heater according to the requirements of the user so as to meet the bathing requirements of the user, thereby avoiding the problem that the energy consumption of the water heater is too high due to the fact that the initial heating temperature of the water heater is set by the user to the maximum, and improving the user experience.
