As shown in fig. 1 to 4, the invention provides a gas water heater and a control method of a booster pump thereof, and a readable storage medium.
In some embodiments, the gas water heater 100 has both a zero cold water mode and a boost mode. As shown in fig. 1, the gas water heater 100 includes a housing 110, and a control device, a burner 120, and an internal cold water pipe 150 and an internal hot water pipe 160 connected to the burner 120 are disposed in the housing 110. The internal cold water pipe 150 is also connected to a return pipe 140. The burner 120 is also connected with a gas pipe 500.
The internal cold water pipe 150 is connected to a water source in the home of the user through a cold water line 200 for supplying cold water to the gas water heater 100. The inner hot water pipe 160 is connected to a water using end 600 in the home of the user through a hot water pipe 300 for providing hot water to the user. A circulation pipeline 400 is connected between the hot water pipeline 300 and the water return pipe 140, and is used for forming a loop with a part of hot water pipes in a zero-cold-water mode, and the water return pipe 140 is provided with a booster pump 130.
In some embodiments, the gas water heater 100 has a preset stop threshold for monitoring the reaching of the stop threshold and controlling the booster pump 130 to stop operating. Specifically, for the booster pump 130, when the booster pump 130 is started, if the water flow rate after the booster pump 130 is started cannot reach the stop threshold or more, the booster pump 130 needs to be controlled to stop in order to protect the booster pump 130 from idling; when the booster pump 130 is stopped, if the water flow rate in the pipe is always kept at the stop threshold or more, the stop condition of the booster pump 130 is not satisfied, the booster pump 130 is not stopped, and the operation state is always maintained. It can be seen that the stop threshold is a key parameter for maintaining the operation state of the booster pump 130 or controlling the stop of the booster pump 130.
In some embodiments, as shown in fig. 2, the control method of the booster pump 130 of the present invention includes the steps of:
s110, receiving an instruction for starting the pressurization mode;
s120, controlling the booster pump 130 to start;
and S130, adjusting the stop threshold value in real time to enable the booster pump 130 to maintain the running state or stop.
Specifically, in step S110, when the gas water heater 100 is in the standby state, the user may switch to the pressurization standby state, and when the water tap of the water end 600 is turned on by the user and the water outlet flow of the gas water heater 100 is greater than or equal to the preset starting water flow, the gas water heater is started to ignite, and in step S120, the booster pump 130 is controlled to start, and the gas water heater 100 enters the pressurization mode. Then, in step S130, the stop threshold of the booster pump 130 is adjusted in real time to maintain the operation state according to the actual demand of the user or stop according to the demand of the user.
In addition, the specific steps included in the control method described in the present invention are not necessarily limited to the described order, and may be executed in any order or in parallel, unless otherwise specified.
In the above solution, the stop threshold of the booster pump 130 is preset in the control device of the gas water heater 100, but the stop threshold is a fixed value that is verified through experiments, but when the gas water heater 100 is installed in different user homes, different working conditions are provided, such as different lengths of water paths, different magnitudes of water pressures, and so on. A fixed value of the stopping threshold obviously does not meet the requirements of all users. Therefore, in the present invention, the stop threshold is adjusted in real time after the booster pump 130 is started, so that the condition that the booster pump 130 can maintain the operation state or stop is satisfied, thereby satisfying the requirements of different users.
In some embodiments, the boost pump 130 has a plurality of operating ranges, and each operating range is provided with a stop threshold. Wherein, the step S130 of adjusting the stop threshold in real time includes: and adjusting the stop threshold of the booster pump 130 at the current operation gear in real time according to the water flow of the gas water heater 100, so that the booster pump 130 maintains the operation state or stops. For example, the gas water heater 100 has 6 boost steps, and a stop threshold corresponding to the boost step may be preset for the 6 boost steps, as shown in table one.
Table one: preset value of boost gear
| Gear of booster pump | Preset value |
| 1 | Value of A |
| 2 | B value |
| 3 | C value |
| 4 | D value |
| 5 | E value |
| 6 | F value |
In detail, the booster pump 130 has a stop threshold value to maintain its operation state or stop at the corresponding operation range. The operation gear of the booster pump 130 can be determined by a user, and can also be determined by the water outlet flow of the gas water heater 100. Optionally, when the water outlet flow of the gas water heater 100 is large, the booster pump 130 correspondingly adopts a high-gear operating gear. The present invention will be described below with an exemplary case where the current operating range of the booster pump 130 is 3 rd.
When the water flow rate after the booster pump 130 is started is less than the stop threshold C, the booster pump 130 is stopped, but the user is in a water using state at this time, and it is obviously not the user's demand to stop the booster pump 130. At this time, the stop threshold C of the booster pump 130 in the current operation range should be adjusted to satisfy the condition that the booster pump 130 can be normally started.
For example, adjusting the stop threshold C of the booster pump 130 in the current operating range in real time according to the water flow rate of the gas water heater 100 to maintain the operation state of the booster pump 130 includes: when the water flow of the booster pump 130 is smaller than or equal to the stop threshold C in the current operating gear, controlling the booster pump 130 to stop; when the water outlet flow of the gas water heater 100 is determined to be greater than or equal to a first preset threshold, the booster pump 130 is controlled to start again after the stop threshold C in the current operating gear is reduced, so that the booster pump 130 maintains the operating state.
In the above scheme, when the water flow rate of the booster pump 130 after being started is less than or equal to the stop threshold C of the booster pump 130 in the current operating range, the booster pump 130 is stopped, but obviously, the user still uses water at this time, and the booster pump 130 needs to be started. At this time, the stop threshold C of the booster pump 130 in the current operation range may be decreased, and then the booster pump 130 may be started again to meet the user's demand.
For example, the booster pump 130 is controlled to start again after the stop threshold C in the current operating range is decreased by Δ L.
However, when the reduced stop threshold C- Δ L is still greater than the water flow rate after the booster pump 130 is restarted, the booster pump 130 may be stopped again, and at this time, the stop threshold C in the current operation range may be reduced by 2 Δ L and then the booster pump 130 may be controlled to be started again, so that the booster pump 130 maintains the operation state. Illustratively, Δ L ranges from 0.5 to 2L/min.
It should be noted that, in a general case, the requirement that the water flow rate of the booster pump 130 after being started is greater than the stop threshold value should be met by adjusting the stop threshold value C of the booster pump 130 in the current gear twice, so as to achieve the purpose of smoothly starting the booster pump 130. However, if the booster pump 130 still fails to start after undergoing two restarts, a malfunction of the booster pump 130 may be signaled, or the above-described method of reducing the stop threshold may be implemented again.
In some embodiments, as shown in fig. 3, the control method includes the steps of:
s110, receiving an instruction for starting the pressurization mode;
s120, controlling the booster pump 130 to start;
s131, judging whether the water flow after the booster pump 130 is started is smaller than or equal to a stop threshold value C, if so, executing a step S132, and if not, determining that the booster pump 130 is normally started;
s132, judging whether the water outlet flow of the gas water heater 100 is larger than or equal to a first preset threshold, if so, reducing the stop threshold C under the current operating gear to C-delta L, then controlling the booster pump 130 to start again, and executing the step S133; if not, the booster pump 130 is kept to be standby;
s133, judging whether the water flow after restarting is less than or equal to a reduced stopping threshold value C-delta L, if so, controlling the booster pump 130 to stop, reducing the stopping threshold value C under the current operating gear to C-2 delta L, then controlling the booster pump 130 to start again, and executing the step S134; if not, determining that the booster pump 130 is normally started;
S134, judging whether the water flow after restarting is less than or equal to the reduced stop threshold value C-2 delta L, and if so, sending a fault signal of the booster pump 130; if not, it is determined that the booster pump 130 is normally started.
After the booster pump 130 is started smoothly, the water pressure with enough pressure is provided for the user, and the water demand of the user is met. When the user finishes using water and turns off the water tap, the booster pump 130 enters the circulation mode in the current operating range by default. However, in some cases, the user needs to turn off the booster pump 130 after the water supply is finished, without entering the zero cold water mode, in order to save energy or reduce cost or noise, etc.
In some embodiments, adjusting the stop threshold of the booster pump 130 in the current operating range in real time according to the water flow rate of the gas water heater 100 to stop the booster pump 130 includes: when the water outlet flow of the gas water heater 100 is smaller than a second preset threshold value, acquiring the circulating water flow of the gas water heater 100 under the current operation gear of the booster pump 130; and controlling the booster pump 130 to stop according to the relation between the circulating water flow and the stop threshold value under the current operation gear.
In some embodiments, controlling the boost pump 130 to stop according to the relationship between the circulating water flow and the stop threshold in the current operating range includes: and controlling the booster pump 130 to stop in response to the circulating water flow rate being less than or equal to the stop threshold value in the current operation gear.
It should be noted here that if the booster pump 130 does not undergo the process of reducing the stop threshold in the above method during the starting process, at this time, the stop threshold of the booster pump 130 in the current operating range is the preset stop threshold C inside the gas water heater 100, and the stop threshold can meet the conditions of the water circuit or the water pressure in the home of the user. If the booster pump 130 is subjected to the process of reducing the stop threshold during the starting process, the stop threshold of the booster pump 130 in the current operating range is the last updated stop threshold, for example, C- Δ L or C-2 Δ L.
The gas water heater 100 may record the updated stop threshold and replace the preset stop threshold C, and then the booster pump 130 may be activated at one time the next time the user activates the boost mode, without having to go through the process of reducing the stop threshold described in the above method, or the number of times the booster pump 130 is activated may be reduced.
In other words, in the process of reducing the stop threshold value in the above method, the gas water heater 100 goes through a process of learning the conditions such as the water circuit or the water pressure in the home of the user once, so that the gas water heater 100 is adapted to the conditions such as the water circuit or the water pressure in the home of the user.
In other embodiments, controlling the boost pump 130 to stop according to the relationship between the circulating water flow and the stop threshold in the current operating range includes: and when the circulating water flow is larger than the stop threshold corresponding to the current operating gear, replacing the stop threshold corresponding to the current operating gear with the circulating water flow, and controlling the booster pump 130 to stop.
In detail, if the flow rate of the circulating water in the circulating pipe 400 of the gas water heater 100 is greater than the stop threshold value at the current operating range, the booster pump 130 is not stopped, and the operating state is maintained. Obviously, it is not sufficient for the user to stop the booster pump 130. At this time, it is necessary to adjust the stop threshold of the booster pump 130 in the current operating range, so that the booster pump 130 can be stopped in time.
When the stop threshold of the booster pump 130 in the current gear is replaced by the circulating water flow, the condition that the circulating water flow is equal to the stop threshold can be at least met, so that the booster pump 130 is stopped in time.
In addition, it should be noted that if the booster pump 130 does not undergo the process of reducing the stop threshold value in the above method during the starting process, at this time, the circulating water flow rate is replaced by the preset stop threshold value C inside the gas water heater 100. If the booster pump 130 is subjected to the above-described process of reducing the stop threshold during the start-up process, then the value of the circulating water flow rate replacement is the last updated stop threshold, for example, C- Δ L or C-2 Δ L. It can be seen that, when the booster pump 130 is controlled to stop, the gas water heater 100 also goes through the process of learning the water path or water pressure and other conditions at home for one time, for the specific reason, refer to the above description, and the present invention is not described herein again.

s110, receiving an instruction for starting the pressurization mode;
s120, controlling the booster pump 130 to start;
s131, judging whether the water outlet flow of the gas water heater 100 is smaller than a second preset threshold value, if so, executing a step S132, and if not, maintaining the normal operation of the booster pump 130;
s132, acquiring the circulating water flow of the gas water heater 100 under the current operation gear of the booster pump 130;
s133, judging whether the circulating water flow is less than or equal to a stop threshold value under the current operation gear, and if so, controlling the booster pump 130 to stop; if not, executing step S134;
and S134, replacing the stop threshold corresponding to the current running gear with the circulating water flow, and controlling the booster pump 130 to stop.
In some embodiments, when the operating range is changed after the boost pump 130 is started, the method for adjusting the stop threshold corresponding to the operating range may be performed as above, and the description of the present invention is omitted here.
