In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
The specific working process of the control method of the gas water heater comprises the following steps:
firstly, presetting at least two groups of reservation information by a client, wherein the reservation information comprises a reservation time period and a preset temperature, specifically, presetting at least two groups of reservation information by the client, and transmitting the at least two groups of reservation information to a gas water heater;
the client can also sequence at least two groups of preset reservation information according to the sequence of the reservation time periods and transmit the sequenced at least two groups of reservation information to the gas water heater;
specifically, according to the use habit of a user family, a plurality of groups of reservation information are preset on a client, the reservation information comprises reservation time periods and preset temperatures, the reservation information is arranged according to the sequence of the reservation time periods, and finally the arranged reservation information is transmitted to a control module of a control system through a signal receiver.
When the preset time period of one group of the preset information is reached, starting ignition heating or heat preservation according to the preset temperature corresponding to the preset time period, specifically, comparing the current return water temperature or the inflow water temperature with the preset temperature; when the current backwater temperature is lower than the preset temperature, the gas water heater starts to ignite and heat; and when the current backwater temperature is greater than or equal to the preset temperature, the gas water heater starts to preserve heat.
Specifically, a temperature sensor of a water return pipeline or a water inlet pipeline of the gas water heater detects the water return temperature or the water inlet temperature at the current time, the detected current water return temperature or the detected water inlet temperature is transmitted to a control module through a signal receiver, and the control module compares the current water return temperature or the water inlet temperature with a preset temperature corresponding to a reserved time period;
when the current backwater temperature is lower than the preset temperature, controlling a circulating pump of the gas water heater to start, and starting ignition heating;
after the operation of ignition heating, the method also comprises the following steps of comparing the water outlet temperature after ignition heating and after the continuous stabilization time with the preset temperature, and when the water outlet temperature after the continuous stabilization time is greater than the sum of the preset temperature and the threshold temperature, starting heat preservation after the circulating pump of the gas water heater operates for mixing time;
wherein, because the outlet water temperature is unstable when the water temperature is just raised, the stable outlet water temperature within a certain time needs to be monitored, and therefore, the stable time is set, and the stable time is generally 5 s; since the temperature will be reduced when the heating is stopped immediately after the temperature of the outlet water rises, the heating is stopped when the temperature is slightly higher than the preset temperature, so as to ensure that the temperature of the outlet water can still reach the preset temperature after the heating is stopped for a certain time, and therefore, a threshold temperature is set, and the threshold temperature is generally 10 ℃; after ignition and heating, the circulating pump runs for a certain time, and the water of the gas water heater is uniformly mixed, so that the mixing time is set, and the mixing time of the circulating pump is generally set to be 60 s;
specifically, after the operation, ignition and heating are carried out, the water temperature is gradually increased, in order to ensure the stability of the water temperature, a temperature sensor of a water outlet pipeline detects the water outlet temperature lasting for 5s, the detected water outlet temperature lasting for 5s is transmitted to a control module through a signal receiver, and the control module compares the water outlet temperature lasting for 5s with the preset temperature corresponding to the reserved time period; when the water outlet temperature lasting for 5s is higher than the preset temperature plus 10 ℃, controlling a circulating pump of the gas water heater to run for 60s and then starting heat preservation;
when the current backwater temperature is greater than or equal to a preset temperature, controlling the gas water heater to start heat preservation;
the gas water heater starts to preserve heat, specifically, during the heat preservation period, the current backwater temperature or the water inlet temperature of the continuous stable time is compared with the preset temperature, and when the current backwater temperature or the water inlet temperature of the continuous stable time is smaller than the difference value between the preset temperature and the heat preservation temperature difference, the gas water heater starts to ignite and heat;
specifically, during the heat preservation period, the temperature of water in the gas water heater is gradually reduced along with the time, so that the change of the water temperature needs to be monitored in real time to ensure that the water temperature in the reserved time period reaches the preset temperature; the heat preservation temperature difference refers to an actual return water temperature or an allowable difference value between an inlet water temperature and a preset temperature of a reserved time period set by a user, can be set through a client according to different use habits of the user, is usually set to be 5 ℃, and can reduce energy consumption and save energy while ensuring that the user can be opened and used immediately in the reserved time period; specifically, when the current return water temperature or the inlet water temperature lasting for 5s is less than the preset temperature-heat preservation temperature difference, the circulating pump is controlled to be started, and the ignition and the heating are carried out again.
In the reserved time period, the water heater is not stopped by the water pump under the judgment conditions, and the water in the water pipe is always kept near the set temperature by combustion heating.
When the reservation time period of one group of reservation information is over, the gas water heater stops running the group of reservation information; when the current time reaches the reservation time period of the next group of reservation information, the control system of the gas water heater executes the reservation information again, heats the water temperature to the preset temperature and keeps the temperature; and stopping the gas water heater until the reservation time period of the last group of reservation information is finished.
The method also comprises the steps that after the gas water heater determines that the current time is in the reservation time period of any one group of reservation information according to at least two groups of preset reservation information, the gas water heater sends a prompt for whether to execute the corresponding reservation information to the client, and the gas water heater is controlled according to the feedback of the client;
specifically, if the current time reaches a reservation time end of a certain group of reservation information, the gas water heater sends a prompt whether to execute the corresponding reservation information to the client, the client pops up a dialog box whether to use gas and water vapor, if 'determination' is selected, the control system defaults to use within 10min, after receiving the instruction, the gas water heater heats return water or inlet water according to a preset temperature and keeps the temperature for 10min, and then the group of reservation tasks is shut down, so that the gas water heater is convenient for the user to use immediately; when "cancel" is selected, the control system executes the set of reservation tasks within a reservation time period; because open the reservation function and just mean that the water pump can not stop constantly, the water heater burns occasionally and guarantees that the water inside the water pipe keeps near the settlement temperature always, and the water pipe cooling is very fast winter, can lead to very big energy waste, and consequently, this function can reduce the energy consumption, the energy saving.

when the water inlet temperature at the current time is less than 35 ℃, controlling a circulating pump of the gas water heater to start, and starting ignition heating;
after the operation of ignition heating, the step of comparing the water outlet temperature which is subjected to ignition heating and lasts for 5s with the preset temperature of 35 ℃, and controlling a circulating pump of the gas water heater to operate for 60s and then start heat preservation when the water outlet temperature which lasts for 5s is higher than 45 ℃;
when the water inlet temperature at the current time is greater than or equal to the preset temperature of 35 ℃, controlling the gas water heater to start heat preservation; during the heat preservation period, comparing the current water inlet temperature lasting for 5s with the preset temperature of 35 ℃, and controlling the gas water heater to start igniting and heating when the current water inlet temperature lasting for 5s is less than 30 ℃;
in the following step 7: 00-8: in the reserved time period of 00, the water heater is not stopped by the water pump and is combusted and heated to ensure that the water in the water pipe is always kept near the set temperature through the judgment conditions;
because the reservation information is a first group, the gas water heater is not used at the moment, the water inlet temperature is lower, and the water pump is started after the reservation time period is reached, the heating is carried out for 3-5 minutes until the temperature is stable, so that the heating can be carried out in advance in the first 5 minutes before the reservation time period is reached, and the stable water temperature can be obtained within the reservation time; in the following steps of 7: 00-8: 00, can be in the range of 6: 55 starting the water pump to heat.
And, the current time reaches 7: when the time is 00, popping up a dialog box whether to use gas, gas and water, if yes, the control system defaults that a user can use the dialog box within 10min, after the gas water heater receives the instruction, heating the return water or the inlet water according to the preset temperature and preserving the heat for 10min, namely, after defaulting for 10min, shutting down the group of reservation tasks, namely 7: 10-8: 00 the reservation function is cancelled; when "cancel" is selected, the control system executes the set of reservation tasks within the reservation time period.
When the current time reaches 18:00, reservation 2 (dishwashing) is performed, at 18: 00-19: in the reserved time period of 00, the water heater is not stopped by the water pump and is combusted and heated to ensure that the water in the water pipe is always kept near the set temperature through the judgment condition;
when the current time reaches 20:00, reservation 3 (bathing of child) is performed, and at 20: 00-21: in the reserved time period of 00, the water heater is not stopped by the water pump and is combusted and heated to ensure that the water in the water pipe is always kept near the set temperature through the judgment condition;
when the current time reaches 21:00, reservation 4 (wife bathing) is performed, and at 21: 00-22: in the reserved time period of 00, the water heater is not stopped by the water pump and is combusted and heated to ensure that the water in the water pipe is always kept near the set temperature through the judgment condition;
when the current time reaches 22:00, reservation 5 (old man bathing) is executed, and at 22: 00-23: and in the reserved time period of 00, the water heater is not stopped by the water pump and is combusted and heated to ensure that the water in the water pipe is always kept near the set temperature through the judgment conditions.
The control system is connected with the client through the signal receiver, and can preset a plurality of groups of reservation information at any time, so that when the water heater is used in a reservation time period, the instant use and the stable water temperature can be ensured; the user can adjust the reserved time period and the preset temperature according to the use habit of the user through the client, the operation of setting the temperature of the water heater in each use is omitted, and the use is more convenient; the client can also remind a user to use, so that the water heater is prevented from heating or preserving heat for a long time in an appointment mode, and the energy consumption of the gas water heater is reduced.
