step S103, detecting whether the total water consumption is more than or equal to the preset water consumption;
if yes, go to step S104; if not, the step S105 is executed;
step S104, recording the water consumption time period and the total water consumption, and starting a capacity increasing function in the same water consumption time period in the next cycle;
and step S105, recording the water consumption time period and the total water consumption.
In step S101, the cycle time is one day, one week, or one month. In this embodiment, the cycle time is one day.
The invention provides a control method of a water heater, which can be used for judging whether the total water consumption exceeds the preset water consumption or not by recording the water consumption time period in one cycle time and the total water consumption in the water consumption time period, and starting a capacity increasing function in advance in the time period exceeding the preset water consumption in the next cycle time, thereby avoiding the problem of insufficient hot water in the bathing process caused by forgetting to start the capacity increasing function of an electric water heater, and improving the use comfort of a user.
The following steps are also included after step S104 or step S105:
step S106, detecting whether a cycle time is reached;
if yes, go to step S107; if not, returning to the step S101;
and S107, in the next period, starting the water heater for heating according to the water consumption time period recorded in the previous period by the preset time, and starting the capacity increasing function in the water consumption time period in which the total water consumption recorded in the previous period is greater than or equal to the preset water consumption.
In this embodiment, the function of opening capacity increase is specifically: the target heating temperature is increased.
And in the next period, starting the water heater for heating according to the water using time period recorded in the previous period and preset time in advance. If the total water consumption in the water consumption time period recorded in the last period is less than the preset water consumption, starting the water heater for a preset time in advance and heating according to the target temperature; and if the total water consumption in the water consumption time recorded in the previous period is more than or equal to the preset water consumption, starting the water heater in advance for the preset time and increasing the target heating temperature for heating. The pre-set time may be 10 minutes, 20 minutes or 30 minutes.
After step S107, the next cycle is entered. In the next period, detecting whether a new water using time period exists or not while 'starting the water heater and heating according to the water using time period recorded in the previous period by a preset time';
if yes, recording a new water consumption time period and the total water consumption;
if not, the water heater is started and heated according to the water consumption time period recorded in the previous cycle and preset time in advance.
In the next period, the water heater is started for a preset time in advance according to the water consumption time period recorded in the previous period, heating is carried out, meanwhile, whether a new water consumption time period exists is detected, data are continuously updated, and the user requirements are met.
In step S101, the step of recording the bathing start time according to the bathing water outlet signal specifically comprises:
step S1001, detecting whether a bathing water outlet signal exists;
if yes, go to step S1002; if not, returning to the step S1001;
and step S1002, recording the bathing start time.
And the bathing start time is recorded according to the bathing water outlet signal, so that the accuracy of recording the bathing start time is ensured.
In step S101, the step of recording the bathing end time according to the bathing stop water signal specifically comprises:
step S2001, detecting whether a signal of water use for stopping bathing exists;
if yes, go to step S2002; if not, returning to the step S2001;
and step S2002, recording the bathing end time.
And recording the bathing end time according to the bathing stop water signal, so as to ensure the accuracy of recording the bathing end time.
For example, within one day of the cycle time, a bathing water outlet signal is detected, the bathing starting time is recorded as T1, after a plurality of times, a bathing water stop signal is detected, the bathing ending time is recorded as T1, the water consumption L1 between T1 and T1 is recorded, and the detected L1 is less than the preset water consumption; detecting a bathing water outlet signal, recording the beginning time of bathing as T2, detecting a bathing water stop signal after a plurality of times, recording the end time of bathing as T2, recording the water consumption between T2 and T2 as L2, and detecting that L2 is more than the preset water consumption; detecting a bathing water outlet signal, recording the beginning time of bathing as T3, detecting a bathing water stop signal after a plurality of times, recording the end time of bathing as T3, recording the water consumption between T3 and T3 as L3, and detecting that L3 is less than the preset water consumption.
In the next day, since the water amount L1 between T1 and T1 is less than the preset water amount, the water heater is turned on and heated according to the target temperature before the time T1; since the water consumption L2 between T2 and T2 is greater than the preset water consumption, the water heater is turned on and the target temperature is increased for heating before the time of T2; since the water amount L3 between T3 and T3 is less than the preset water amount, the water heater is turned on and heated according to the target temperature before the time of T3.
Step S102, the step of obtaining the total water consumption in the bathing time according to the bathing start time and the bathing finish time specifically comprises the following steps:
detecting whether the interval time between the bathing end time and the next bathing start time is less than a preset time interval;
if so, judging the water consumption state as a continuous water consumption state, and adding the water consumption of the previous and the next two times to obtain the total water consumption;
if not, the bathing device is judged to be in a discontinuous water using state, and the total water using amount in the bathing time is obtained according to the bathing finishing time corresponding to the bathing starting time.
Whether the water heater is in the continuous water use state or not is judged according to the opening and closing interval time, and the problem that the water heater is recorded into a two-section water use state due to the fact that a user temporarily closes a water source in the continuous water use state, and the water heater is opened after being temporarily closed, and energy is wasted can be avoided.
For example, the bathing water outlet signal is detected, the bathing start time is recorded as T4, after a certain time, the bathing stop water use signal is detected, the bathing end time is recorded as T4, the water consumption between T4 and T4 is recorded as L4, after a certain time, a bathing water outlet signal is detected, the bathing start time is recorded as T5, after a certain time, the bathing stop water use signal is detected, the bathing end time is recorded as T5, and the water consumption between T5 and T5 is recorded as L5. Judging whether the interval time between the bathing ending time T4 and the next bathing starting time T5 is smaller than a preset time interval, if so, judging that the time from T4 to T4 and the time from T5 to T5 are in a continuous water using state, and the total water using amount is L4+ L5. If the time interval is larger than the preset time interval, the water supply state is judged to be a discontinuous water supply state.
The preset interval time may be 1-5 minutes.
The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
