It is worth to be noted that the technical scheme of the invention is suitable for water storage type water heaters, including electric heating water storage type, combustion heating water storage type and water storage type water heaters which use other energy sources for heating.
The following control method of the water heater provided according to the above structure of the water heater comprises the following steps:
s10: counting the water consumption times of each water consumption time period of each day in the previous period, wherein when the total water consumption times of the water consumption time periods is greater than or equal to the preset times, the time period is a regular time period;
in this embodiment, the cycle is exemplified by 21 days, and each day is divided into six time periods, which are respectively 3: 00-7: 00, 7: 00-11: 00, 11: 00-15: 00, 15: 00-19: 00, 19: 00-23: 00, 23: 00-3: 00. During each period, the number of times the user uses water, and the amount of water used per time, is recorded. The total number of water usage times in a water usage period is, the total number of water usage times in the water usage period in 21 days of a cycle, and the number of water usage times per day in each period may be different, for example, 7 on monday to friday: the average water consumption frequency of 00-11: 00 is 0.5, and the water consumption frequency of saturday and sunday is 7: the average water consumption frequency of 00-11: 00 is 3.5. The preset number is 11, for example, and may be set according to the requirement of the user in some embodiments. That is, when the user uses water for a certain period of time of 21 days for 11 times or more, the period is set as a regular period, and the water consumption is controlled to be increased by the period 19: 00-23: 00 as an example. When the user uses water less than 11 times in a certain period of 21 days, the period is set as an irregular period, and the period is set as a period of 11: 00-15: 00 as an example. The water consumption time period is divided into regular time periods and irregular time periods through statistics of the total water consumption times in the water consumption time period.
Of course, before statistics, the heating control needs to be periodically set, each period time length and water use time period are divided, and the water use condition of the user in each water use time period, namely the water use times, the water use frequency, the water use temperature and the water use amount, is recorded. This process, for the learning process of the water heater, in the first cycle, the water usage parameter not set by the user is installed with preset parameters for operation, for example, the heating time is preset to 19: 00-23: 00 and 7: 00-11: 00, presetting a sleep time period as 23: 00-3: 00, and the like. The second overtime period is set according to the water consumption condition of the first period of the user, and the third period is adjusted according to the water consumption conditions of the first period and the second period.
S20: calculating the respective average water consumption of all regular time periods, wherein when the average water consumption is greater than or equal to a first preset water consumption, the regular time period corresponding to the average water consumption is a high-temperature time period;
in the embodiment, in the regular time periods, the water consumption of each time of water consumption in all the regular time periods is counted, the total water consumption in each regular time period is calculated, and the average water consumption of each day of water consumption in each time period in the period is obtained by dividing the total water consumption by the total days of water consumption. For example, 19 per day for 21 days was calculated: 00-23: 00 water consumption, and then adding the water consumption in 21 time periods in the period to obtain a time period 19: and (3) dividing the total water consumption in the period of 00-23: 00 by the cycle days of 21 days to obtain the average water consumption of each day in the time period. And comparing the average water consumption with the first preset water consumption, wherein when the average water consumption is more than or equal to the first preset water consumption, the time period corresponding to the average water consumption is a high-temperature time period. The first preset water usage is for example 20L, i.e. when the time period 19: when the average water consumption of 00-23: 00 is more than or equal to 20L, the time period is 19: and the high-temperature time period is 00-23: 00. Correspondingly, when the average water consumption is less than the first preset water consumption, the time period corresponding to the average water consumption is a low-temperature time period. The first preset water usage is for example 20L, i.e. when time period 7: when the average water consumption of 00-11: 00 is less than 20L, the time period is 7: and the low-temperature time period is 00-11: 00.
S30: heating the water temperature in the water heater to a first preset temperature in a high-temperature time period.
When the current water using time period is the high-temperature time period, the water temperature in the inner container is heated to a first preset water temperature through the heating device. The first preset water temperature can be set for the water heater or can be set for a user. The water temperature of the first preset water temperature is higher water temperature, such as 70 ℃, within a high-temperature time period, the water consumption frequency and the water consumption are higher, and the requirement of a user can be met only by the higher water temperature.
In the embodiment, the total water consumption times of each water consumption time period of each day in the previous period are counted, the total water consumption times of each time period are compared with the preset times, and when the total water consumption times of the water consumption time periods are greater than or equal to the preset times, the time periods are regular time periods; then, in regular time periods, the respective average water consumption of all regular time periods is counted, each average water consumption is compared with a first preset water consumption, and when the average water consumption is larger than or equal to the first preset water consumption, the regular time period corresponding to the average water consumption is a high-temperature time period; heating the water temperature in the water heater to a first preset temperature in a high-temperature time period; through the steps, the water is heated according to the water consumption condition of a user, the water is heated to the first preset water temperature only in the high-temperature time period, and the energy conservation of the water heater is realized in the time period with less water while the water consumption peak period is ensured to have enough water available.
In order to improve the energy saving efficiency of the water heater, the method further comprises the following steps after the step of counting the average water consumption of all regular time periods:
when the average water consumption is less than the first preset water consumption, the regular time period corresponding to the average water consumption is a low-temperature time period; and heating the water temperature in the water heater to a second preset temperature in a low-temperature time period.
In this embodiment, the second preset water temperature is lower than the first preset water temperature, and in the low-temperature time period, the number of times of using water by the user is large, but the water consumption per time is low. For example, to ensure that the user uses water without wasting energy, heating the water to a second preset water temperature lower than the first preset water temperature is a good choice. The specific value of the second preset water temperature can be set by the water heater in a default mode or can be set by a user according to actual requirements. Of course, a comparison table of water temperature and water consumption can be provided, and the water consumption corresponds to the water temperature. Through the setting of low temperature time quantum to the temperature heating in the low temperature time quantum with the water heater is to the preset temperature of second, satisfies user's water and in the time, practices thrift the electric energy as far as possible, avoids hot water surplus.
In order to further improve the utilization rate of the electric energy and avoid the surplus of hot water, after counting the number of water usage times of each water usage time period of each day in the previous period, the method further comprises the following steps:
when the water consumption times in the water consumption time period are less than the preset times, the time period is an irregular time period; and setting the water heater to be in a dormant state in an irregular time period.
In the embodiment, in an irregular time period, the water consumption frequency and the water consumption of the user are both small, namely the water consumption of the user is low. In this case, if the water heater is heated for a long time, the hot water is not used for a long time, and the energy of the heating person and the heat preservation water is wasted. The sleep state comprises a shutdown state and a low-temperature-keeping state, and can be selected according to the actual requirements of users. For example, in a certain period of time, the user never uses water, and the water heater can be shut down; if the water consumption times of the user are more but less than the first preset times within a certain time period, the water heater can be subjected to heat preservation treatment. Specifically, when the user sets the water heater, and when the water heater is automatically adjusted, the water heater is subjected to energy conservation and water supply unification.
In order to ensure sufficient water use for the user, the method further comprises the following steps after the step of setting the water heater to the dormant state in the irregular time period:
and when the water consumption reaches the second preset water consumption, the water temperature of the water heater is heated to a third preset temperature from the time when the water consumption reaches the second preset water consumption.
In this embodiment, the second predetermined water consumption is greater than the first predetermined water consumption, for example, 50L to 70L. Due to living needs, the water consumption in the home is suddenly and greatly increased at some time, for example, guests come in. When the total water consumption of the day is larger than or equal to the second preset water consumption, the water demand of the user at home today is particularly large. At this time, the water heater is not limited by a high-temperature time period, a low-temperature time period and dormancy, and the water temperature is heated to a third preset water temperature all the time. The third preset water temperature can be larger than the first preset water temperature, can also be smaller than the first preset water temperature, and can even be adjusted and set according to a control instruction of a user. Through the setting of the second predetermined water consumption to the water consumption on the same day is from the time that reaches the second predetermined water consumption, with the temperature heating of water heater to the third predetermined temperature, abundant assurance user's water demand is favorable to the better use water heater of user.
