The following control method of the electric water heater provided according to the above structure of the electric water heater comprises the following steps:
s10, receiving a control instruction of a user;
in this embodiment, there are various ways for a user to send a control instruction to the electric water heater, for example, the user may send the control instruction through a wireless network by using a mobile terminal (e.g., a remote controller, a mobile phone, a tablet electric energy, an intelligent bracelet, an intelligent watch, etc.), and the user may also send the control instruction through a physical key electrically connected to a main control board of the electric water heater. It can be understood that before the user sends the control instruction to the electric water heater through the mobile terminal, a communication connection needs to be established with the electric water heater. That is, only on the basis that the mobile terminal establishes communication connection with the electric water heater, the mobile terminal can control the electric water heater through a control instruction, or information interaction between the mobile terminal and the electric water heater needs to be mutually authenticated. After receiving the control instruction of the user, the electric water heater starts the heating program in the following embodiment.
S20, setting the sleep time interval in each day in the cycle according to the control instruction;
in this embodiment, the number of the sleep periods may be multiple, and the sleep periods may be continuous or discontinuous, for example, 23:00 to 7:00, 11:00 to 15:00, and the like. The time corresponding to the sleep time interval can be set according to the requirements of users, and certainly, the electric water heater can also be set according to the water use habits of the users and the current actual water use conditions. The period may be set according to the actual situation of the user, and 21 days is taken as an example. Of course, the electric water heater can obtain the current time in various ways, and the electric water heater can have a timing device by itself or can obtain the current time through a wireless network. By accurately acquiring the current time, the current time interval can be accurately judged.
And S30, adjusting the electric water heater to a sleep state when the electric water heater is in the sleep time period.
When the electric water heater is in the reserved sleep mode, when the current time interval belongs to the sleep time interval, the working state of the electric water heater is adjusted to be in the sleep state. In the dormant state, the electric water heater is not heated and does not keep warm, is in the lowest power consumption state, but can receive any operation instruction of a user at any time. When the electric water heater works, the time periods except the dormant time period are non-dormant time periods, and the non-dormant time periods comprise a heat preservation time period and a heating time period. The working condition of the non-sleep time period is set by a user, and of course, the electric water heater can also be set according to the use habit of the user and the current water use condition. In this embodiment, the sleep time period is a forced sleep time period, that is, only in the reserved sleep mode, the user sets the sleep time period, and in the set time period, the electric water heater is forced to sleep. The sleep time interval is 23: 00-7: 00, 11: 00-15: 00, and the non-sleep time interval is: 7: 00-11: 00, 15: 00-23: 00. Through the setting of dormancy time quantum for electric water heater's consumption reduces by a wide margin.
In this embodiment, the electric water heater first receives a control instruction of a user; setting a plurality of dormant time periods in each day in the period according to the control instruction; when the electric water heater is in the dormant period, the electric water heater is adjusted to be in the dormant state; in the technical scheme of the embodiment, the user makes the electric water heater forcibly sleep in the sleep time period by reserving the sleep mode so as to reduce the energy consumption of the electric water heater, and meanwhile, the user can eliminate the interference of the prompt tone and the like of the electric water heater to the user by the mode.
In order to make the sleep time period more suitable for the water use habit of the user, the method further comprises the following steps after the step of setting the sleep time period in each day of the cycle according to the control instruction:
s40, recording and counting the water consumption of each water consumption time period every day in the 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. 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, during the learning of the water heater, is performed during a first period according to preset parameters, such as a first heating time period preset at 19 a per day, for other water usage parameters not set by the user: 00-22: 00 and 7: 00-11: 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.
And S50, when the water consumption is less than or equal to the first preset water consumption, adding the water consumption time corresponding to the water consumption to the dormancy time.
And (3) counting the water consumption of each time of water consumption in all the non-water consumption time periods, calculating the total water consumption in each non-water consumption time period, and dividing the total water consumption by the total days of water consumption to obtain the average water consumption of each time period per day of water consumption in each period. For example, first, 11: 00-15: 00 water consumption, and then adding the water consumption in 21 time periods in the period to obtain a water consumption in 11 time periods: and (3) dividing the total water consumption in the period of 00-15: 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, and when the average water consumption is less than or equal to the first preset water consumption, enabling the time period corresponding to the average water consumption to be included in the dormancy period. The first preset water usage is 20L, i.e. when the time period 11: when the average water consumption of 00-15: 00 is less than or equal to 20L, the time period is 11: 00-15: 00 will be part of the sleep period of the next cycle. Of course, if it is a sleep period, when the statistical average water consumption is greater than the first preset water consumption, the sleep period can be removed, that is, the electric water heater is no longer set to sleep state in the sleep period.
In this embodiment, the electric water heater records and counts the actual water consumption condition in the user cycle, adjusts the sleep time interval according to the actual water consumption condition, adds the water consumption time interval to the sleep time interval when the average water consumption is less than or equal to the first preset water consumption, and removes the sleep time interval when the average water consumption is greater than the first preset water consumption.
In order to further reduce the energy consumption of the electric water heater, the control method of the electric water heater further comprises the following steps:
recording and counting the total water consumption of the first three days;
in this embodiment, the electric water heater records and counts the water consumption of three days before the day, that is, the water consumption of each time period of the three days before is added to obtain the total water consumption of three days.
And when the total water consumption is less than or equal to the second preset water consumption, setting the whole day as a dormant period.
The second preset water consumption is larger than the first preset water consumption, for example, 0L-10L. Due to the needs of life, the water consumption in the home is suddenly and greatly reduced at some time, for example, the user goes out for several days. When the total water consumption of the current three days is less than or equal to the second water consumption, the water demand of the user in the family of the days is very small. At this time, the water heater is not limited by a high-temperature time period, a low-temperature time period, dormancy and the like, and the electric water heater is always set to be in the dormant state.
In order to improve the energy saving efficiency of the water heater, the step of adjusting the electric water heater to the dormant state when the electric water heater is in the dormant period further comprises the following steps:
when the water consumption reaches the third preset water consumption, the water temperature of the electric water heater is heated to the first preset temperature from the moment when the third preset water consumption is reached.
In this embodiment, the third 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 more than or equal to the third preset water consumption, the current water demand of the user at home is particularly large. At the moment, the water heater is not limited by a high-temperature time period, a low-temperature time period, dormancy and the like, and the water temperature is heated to the first preset water temperature all the time. The first preset water temperature can be adjusted and set according to a control instruction of a user. Through the setting of third predetermined water consumption to water consumption on the same day is from the time that reaches third predetermined water consumption, heats the temperature of electric water heater to first predetermined temperature, and the abundant water demand that has guaranteed the user is favorable to the better use water heater of user.
The invention further provides an electric water heater comprising:
a receiving module 10, configured to receive a control instruction of a user;
in this embodiment, there are various ways for a user to send a control instruction to the electric water heater, for example, the user may send the control instruction through a wireless network by using a mobile terminal (e.g., a remote controller, a mobile phone, a tablet electric energy, an intelligent bracelet, an intelligent watch, etc.), and the user may also send the control instruction through a physical key electrically connected to a main control board of the electric water heater. It can be understood that before the user sends the control instruction to the electric water heater through the mobile terminal, a communication connection needs to be established with the electric water heater. That is, only on the basis that the mobile terminal establishes communication connection with the electric water heater, the mobile terminal can control the electric water heater through a control instruction, or information interaction between the mobile terminal and the electric water heater needs to be mutually authenticated. After receiving the control instruction of the user, the electric water heater starts the heating program in the following embodiment.
The adjusting module 20 is used for setting the sleep time interval in each day in the cycle according to the control instruction;
in this embodiment, the number of the sleep periods may be multiple, and the sleep periods may be continuous or discontinuous, for example, 23:00 to 7:00, 11:00 to 15:00, and the like. The time corresponding to the sleep time interval can be set according to the requirements of users, and certainly, the electric water heater can also be set according to the water use habits of the users and the current actual water use conditions. The period may be set according to the actual situation of the user, and 21 days is taken as an example. Of course, the electric water heater can obtain the current time in various ways, and the electric water heater can have a timing device by itself or can obtain the current time through a wireless network. By accurately acquiring the current time, the current time interval can be accurately judged.

When the electric water heater is in the reserved sleep mode, when the current time interval belongs to the sleep time interval, the working state of the electric water heater is adjusted to be in the sleep state. In the dormant state, the electric water heater is not heated and does not keep warm, is in the lowest power consumption state, but can receive any operation instruction of a user at any time. When the electric water heater works, the time periods except the dormant time period are non-dormant time periods, and the non-dormant time periods comprise a heat preservation time period and a heating time period. The working condition of the non-sleep time period is set by a user, and of course, the electric water heater can also be set according to the use habit of the user and the current water use condition. In this embodiment, the sleep time period is a forced sleep time period, that is, only in the reserved sleep mode, the user sets the sleep time period, and in the set time period, the electric water heater is forced to sleep. The sleep time interval is 23: 00-7: 00, 11: 00-15: 00, and the non-sleep time interval is: 7: 00-11: 00, 15: 00-23: 00. Through the setting of dormancy time quantum for electric water heater's consumption reduces by a wide margin.
