When the gas water heater is used, the water inlet flow of the gas water heater is controlled to be the first smaller water inlet flow, so that the rapid heating is realized, and it can be understood that when the combustion quantity of the gas water heater is kept at a certain time, the smaller the flow is, the faster the heating speed is, the less the consumed time is, and the time is shortened, so that the water resource and the gas resource consumed in the time are saved.
In addition, when the gas water heater is controlled to feed water at the first water inlet flow rate, the water outlet temperature of the gas water heater needs to be detected in real time, the time point of recovering normal water feeding of the gas water heater can be determined by comparing the water outlet temperature with the adjacent temperature interval, namely the time point of controlling water feeding of the gas water heater by using the second water inlet flow rate, it needs to be emphasized that the adjacent temperature interval corresponds to the water using temperature (namely the set temperature) preset by a user, generally, the temperature in the adjacent temperature interval is smaller than the water using temperature, so that when water enters at a small flow rate, the water outlet temperature reaches the vicinity of the water using temperature, the water inlet at a large flow rate is recovered, the efficiency of increasing the water temperature at the beginning of starting is optimized, and the constant temperature speed is also improved.
Wherein, can understand, first inflow and second inflow are the flow of external water source drainage income water in to the water tank of gas heater.
Furthermore, when the outlet water temperature of the gas water heater is detected, the outlet water temperature can be detected by arranging a temperature sensor at the outlet end of the gas water heater, and of course, other modes can be adopted, such as arranging a temperature sensor at the position of the water mixing valve.

EXAMPLE III
As shown in fig. 3, the present embodiment provides a control method for a gas water heater, including: step S302: determining a first water inlet flow and a second water inlet flow corresponding to the gas water heater; step S304: controlling the gas water heater to feed water at a first water inlet flow rate, and detecting the water outlet temperature of the gas water heater; step S306: determining the water outlet temperature of the gas water heater; step S308: acquiring a set temperature corresponding to the gas water heater; step S310: determining an adjacent temperature interval according to the set temperature; step S312: and if the water outlet temperature is in the adjacent temperature range, controlling the gas water heater to feed water at a second water inlet flow.
Wherein the first water inflow rate is less than the second water inflow rate.

The starting instruction is received before the first water inlet flow and the second water inlet flow are determined, the two water inlet flows are determined according to the starting instruction, and the two water inlet flows are obtained only after the starting instruction is received, so that the energy consumption when the gas water heater is not used is reduced, and meanwhile, the standby loss of internal electronic devices is also reduced.
It can be understood that the starting instruction is an instruction that a user needs to use the gas water heater to generate hot water
Further, after a starting instruction is received, a lower front cleaning mode needs to be executed firstly, specifically, the operation parameters corresponding to the front cleaning mode are determined, including rotating speed, time and the like, and when the fan in the gas water heater is controlled to operate according to the operation parameters, the combustion residues in the last operation can be blown out outwards, so that the influence on the current operation is reduced.
Wherein, the technical staff in the field should know that the preceding mode of cleaning is gas heater self inherent mode, cleans under the mode before, can control gas heater's fan operation to blow out the remaining impurity after last work in the pipeline, in order to reduce the influence to this burning heating.
Furthermore, before water is fed at the second water inlet flow with a larger flow, the water feeding time of the first water inlet flow is limited as the pre-cleaning time of the operation parameter, namely, when the gas water heater operates in the pre-cleaning mode, water is fed at the first water inlet flow with a smaller flow, and the water outlet speed of hot water is increased in the pre-cleaning time.
In addition, after the gas water heater executes the front cleaning mode, namely after the running time of the gas water heater reaches the front cleaning time, the gas water heater is controlled to ignite and burn, the water outlet temperature can be continuously increased after burning, and at the moment, the water inlet flow of the gas water heater can be adjusted according to the change of the water outlet temperature, so that the effects of realizing quick adjustment and reducing unnecessary resource waste are facilitated.
In this embodiment, in the operation process of the gas water heater, no matter when the combustion stopping instruction is received, it indicates that the user does not need to continue to burn hot water at this time, so the gas water heater needs to stop burning according to the combustion stopping instruction, and unnecessary waste of gas resources and water resources can be reduced.
EXAMPLE five
As shown in fig. 5, the present embodiment provides a gas water heater 100 including a processor 120 and a memory 110. The processor 120 is electrically connected to the memory 110, the memory 110 stores programs or instructions, and the processor 120 is configured to implement the steps of the control method when executing the programs or instructions, so that the gas water heater 100 of the present invention has all the advantages of the control method in any of the above embodiments, and details are not described herein.
In addition, the gas water heater 100 includes a water server (i.e., water volume server) at the water inlet end, water flow rate sensors, a temperature sensor at the water outlet end, and a processor 120.
When the water heater just starts burning, the water inlet flow is adjusted to be smaller through the water server. The processor 120 then controls the fast combustion, and since the water flow is now reduced by the water servo, the heating rate will become faster than the original flow. When the processor 120 detects that the temperature of the outlet water temperature sensor is close to the set temperature, the processor 120 drives the water servo to re-adjust the water flow to the initial value.
When the hot water at the water outlet end reaches the set temperature, compared with the initial water flow before the water server is turned down, the waste water and the fuel gas which are not hot enough are reduced, the energy-saving effect is achieved, and the constant temperature speed is relatively improved.
Further, when the control method is implemented by applying the embodiment, the controller drives the water servo to adjust the water flow to be small simultaneously during front cleaning according to the initial water flow when the machine is started. After ignition and combustion, when the water outlet temperature detected at the water outlet end of the water heater is close to the set temperature, the controller drives the water servo to rapidly adjust the water flow, and in the process of increasing the water flow, the water outlet temperature is controlled to be equal to the set temperature, and the temperature of the hot water is kept stable. As shown in fig. 6, the control method includes step S602: performing initialization on the gas water heater; step S604: judging whether water inflow is detected; if yes, executing step S606 to judge whether the initial water flow of the inlet water is larger than the target turn-down value; if not, returning to the step S602; if the determination result in the step S606 is yes, the step S608 is executed: driving a water quantity server to reduce the water flow; if the determination result in step S606 is no, return is made to step S604; step S610: judging whether the water flow reaches a target turn-down value or not; if yes, go to step S612: judging whether the previous cleaning is finished or not, and returning to the step S608 if not; when the determination result in step S612 is yes, step S614 is executed: ignition combustion constant temperature control; if the determination result in step S612 is no, return is made to step S610; step S616: judging whether the water outlet section reaches a set temperature or not; if yes, go to step S618: driving a water quantity server to increase the water flow; if the determination result in step S616 is no, return is made to step S614; step S620: judging whether combustion is stopped; if yes, the process returns to step S602, otherwise, step S622 is executed: and (5) controlling the constant temperature.
