Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
Gas water heaters are now in common use, and the constant temperature effect of the gas water heater is the most concerned use experience of users. The existing gas water heater includes: a proportional valve and segmentation valve for controlling gas heater operating mode, wherein, the proportional valve is the governing valve that is used for adjusting gas and air ratio, the segmentation valve is used for controlling the quantity that puts into the fire row when burning, in normal operating mode, gas heater adjusts the gas volume through controlling proportional valve and segmentation valve, in order to realize the control of gas heater water outlet constant temperature, current gas heater control method can reach good constant temperature effect under most circumstances, however, when gas heater meets the special condition that the gas of gas quality change or atmospheric pressure shakiness etc. changes, current gas heater control method can frequently switch over gas heater's segmentation valve under these special burning operating modes, and then lead to leaving water temperature fluctuation, can't reach the constant temperature effect, influence user's use experience.
Because the gas heater is by proportional valve and sectional valve to control the gas volume size in order to reach the constant temperature purpose, if cold water pressure of intaking is unstable or gas pressure is unstable, the gas quality is not good, and the temperature can't be stabilized at user's settlement temperature all the time, the control panel will frequently guarantee that the temperature is stable through adjusting gas proportional valve and sectional valve automatically regulated gas volume, and frequently switch the sectional valve and can cause the temperature fluctuation.
In view of the above problems, an embodiment of the present invention provides a method for controlling a gas water heater, in the embodiment of the present invention, an exemplary gas water heater includes two segment valves, i.e., a segment valve 1 and a segment valve 2, and the segment valves of the gas water heater have 3 working states: the non-opening section valve, the opening section valve 1 and the opening section valve 2 respectively correspond to different power sections, for example: for a gas water heater with 30kw, the power section of the above-mentioned 3 operation state control is as follows: 2.6-11 kw, 11-21 kw, 21-30 kw. It should be understood that the present invention is not limited thereto. As shown in fig. 1, the control method of the gas water heater specifically includes the following steps:
step S101: and monitoring the working state and the water outlet temperature of a sectional valve in the gas water heater.
The gas water heater includes a plurality of segment valves, the working states of the segment valves are divided into two working states of opening and closing, and different segment valves correspond to different power sections, for example, in the process of opening the segment valve 1, the corresponding power section is 11 kw-21 kw, the power section can be determined by the performance test of the gas water heater, and different models correspond to different power sections, which is not limited in the present invention. The water outlet temperature is the water temperature of the water outlet of the gas water heater.
Step S102: and judging whether the switching condition of the working state of the sectional valve in the preset time before the current moment meets the switching requirement of the preset sectional valve.
The preset time is the minimum regulation and control time of the segment valve of the gas water heater, and may be specifically set according to the requirement of the thermostatic control precision of the gas water heater, wherein in the embodiment of the present invention, the preset time is described by taking 3min as an example, which is only taken as an example and is not limited thereto. The preset switching requirement of the segment valve is used for judging whether the segment valve is frequently switched to influence the constant temperature effect of the discharged water, and the preset switching requirement of the segment valve can be set according to the constant temperature control precision requirement of a specific gas water heater, and the invention is not limited by the requirement.
Step S103: and when the switching condition of the working state of the sectional valve is monitored within the preset time length to meet the switching requirement of the preset sectional valve, controlling the sectional valve to maintain the current working state.
Wherein, if the switching condition of monitoring the operating condition of section valve in predetermineeing the duration satisfies predetermineeing section valve switching requirement, then explain that there is frequent switching influence to go out the homothermal phenomenon of water in the section valve now, in order to guarantee the homothermal effect of water, control section valve and maintain current operating condition and carry out work, for example: the current working state of the section valve 1 and the section valve 2 is that the section valve 1 is opened, and the section valve 2 is closed, so that the states of the two section valves are locked, namely the section valve 1 is controlled to be always in an opened state, and the section valve 2 is controlled to be always in a closed state.
Step S104: and adjusting a proportional valve in the gas water heater based on the preset outlet water temperature requirement and the current outlet water temperature so that the outlet water temperature of the gas water heater meets the preset outlet water temperature requirement.
Wherein, this preset leaving water temperature requirement is the leaving water temperature that the user set for at gas heater according to the demand, for example: 40 ℃ and the like, and because the working states of all the segment valves in the gas water heater are locked, namely fixed and unchanged, the proportional valves are adjusted by monitoring the current water outlet temperature of the gas water heater and the preset water outlet temperature requirement, and the water outlet temperature is controlled by adjusting the air inlet amount to maintain the water temperature requirement set by a user. Specifically, the outlet water temperature control can be performed by PID, that is, the opening of the proportional valve is controlled to adjust the corresponding power, such as: and adjusting through PID according to the water outlet temperature and the water flow, calculating corresponding power, and controlling the opening of the proportional valve to be close to the temperature set by the user.
By executing the steps, the control method of the gas water heater provided by the embodiment of the invention maintains the current working state of the segment valve unchanged through monitoring the working state of the segment valve in the gas water heater and according to the switching condition of the working state of the segment valve within the preset time length, so that the gas water heater burns with a fixed fire row number, and the outlet water temperature is adjusted by controlling the proportional valve, thereby avoiding the problem of outlet water temperature fluctuation caused by frequently switching the segment valve when the gas water heater encounters the conditions of gas quality change or unstable air pressure and the like, ensuring that the outlet water temperature approaches the set temperature of a user, maintaining the constant temperature effect without additionally performing constant temperature assistance, and ensuring the use experience of the user.
Specifically, in an embodiment, the step S102 specifically includes the following steps:
step S201: and judging whether the switching times of the working state of the sectional valve in the preset time length reach the preset switching times or not.
Wherein, the preset switching times are more than 1. In the embodiment of the present invention, the preset switching frequency is 2 for example, and in practical applications, the preset switching frequency may be flexibly adjusted according to the outlet water temperature constant temperature control precision of the gas water heater, and the present invention is not limited thereto.
Step S202: and when the switching times of the working state of the sectional valve within the preset time reach the preset switching times, judging that the switching condition of the working state of the sectional valve meets the switching requirement of the preset sectional valve.
Specifically, if the number of switching times of the working state of the segment valve within the preset time is large, it is indicated that the outlet water constant temperature of the gas water heater is easily affected, and in order to ensure the outlet water constant temperature effect, the switching requirement of the preset segment valve is considered to be met when the number of switching times of the working state of the segment valve reaches the preset switching times. In practical application, when gas quality changes or air pressure is unstable, the actual working state of the segment valve is the working state which is frequently switched back and forth, in order to improve the condition of judging whether the gas water heater has abnormal gas or not and improve the accuracy of controlling the gas water heater, when the switching frequency of the working state of the segment valve reaches the preset switching frequency within the preset time, the embodiment of the invention accurately judges that the switching condition of the working state of the segment valve meets the switching requirement of the preset segment valve through the following steps.
And judging whether the working state of the sectional valve is switched from the first working state to the second working state within a preset time length, and switching back to the first working state from the second working state again.
As shown in table 1, the first operating state is an initial state before each segment valve is switched within 3min, the second operating state is an operating state after each segment valve is changed after the switching process occurs, and after the switching process occurs again, each segment valve is switched to the initial state before the switching occurs.
When the working state of the segment valve is switched from the first working state to the second working state within the preset time length and is switched back to the first working state from the second working state again, the switching condition of the working state of the segment valve is judged to meet the switching requirement of the preset segment valve. When the fire grate is frequently switched, the segment valve is controlled to maintain the current working state, namely the initial state working of the fire grate is switched, and the specific details are shown in a column of intelligent locking states in table 1.
TABLE 1
Specifically, when taking place intelligent locking state, fixed fire row maintains current segmentation valve state unchangeable promptly, and control the temperature through the adjustment proportional valve and be close to the settlement temperature, do not adjust the segmentation valve promptly, carry out temperature PID regulation through the adjustment proportional valve, because segmentation valve operating condition is fixed, combustion unit can restrict combustion power, and the mode of adjusting the proportional valve through PID makes the leaving water temperature infinitely close user's settlement temperature simultaneously to guarantee the constant temperature effect of leaving water temperature.
Specifically, in an embodiment, before the step S102 is executed, the control method further includes the following steps:
step S105: monitoring an operating parameter of the gas water heater.
Wherein the operating parameters include at least: the water inlet temperature, the water inlet flow and the target water outlet temperature set by a user. The temperature of intaking is the temperature of gas heater's water inlet, and the inflow is the inflow in the unit interval, if: the water inlet flow is 10L/min, and the like, and the target water outlet temperature set by the user is the water temperature required by the user for bathing.
Step S106: and judging whether the operation parameters of the gas water heater meet the preset operation state requirement in the preset time.
Wherein, the preset operation state requirement is the operation parameter requirement of the gas water heater working under a stable condition. In practical application, except for the switching of the frequent working state of the switching valve caused by abnormal gas, if a user changes the target outlet water temperature during the normal working of the gas water heater, the target outlet water temperature is as follows: the original temperature of 40 ℃ is changed into 50 ℃, or the inflow flow is increased due to the increase of the outflow flow, the fluctuation of the inflow and outflow flow is increased, or the inflow temperature is lowered at night in winter, and the like, the gas water heater can also adjust the fire grate number by switching the working state of the segment valve to adapt to the change of external conditions, so that the step S102 is executed only when the running parameters of the gas water heater meet the preset running state requirement within the preset time period in order to further improve the control accuracy of the gas water heater and avoid the influence of the change of the external conditions on the working state of the segment valve.
Specifically, the step S106 includes the following steps:
judging whether the target outlet water temperature changes within a preset time length; when the target outlet water temperature is not changed within the preset time length, judging whether the inlet water temperature meets the preset temperature fluctuation range within the preset time length; when the inlet water temperature meets the preset temperature fluctuation range within the preset time length, judging whether the inlet water flow meets the preset flow fluctuation range within the preset time length; and when the inflow water flow meets the preset flow fluctuation range within the preset time, judging that the parameter state of the gas water heater meets the preset operation state requirement. And when the target outlet water temperature changes within the preset time length, and/or the inlet water temperature does not meet the preset temperature fluctuation range, and/or the inlet water flow does not meet the preset flow fluctuation range, returning to the step S105. Therefore, the accuracy of control of the gas water heater is further improved, the influence on the working state of the sectional valve due to the change of external conditions is avoided, the accurate control on the sectional valve is realized, and the constant temperature of the discharged water of the gas water heater is favorably ensured.
Illustratively, the preset operation state requires that when it is detected that the user enters the bathing mode, particularly, after the external conditions affecting the outlet water temperature are stable, namely the set temperature, the inlet water temperature and the water flow are stable, the following conditions are simultaneously satisfied within any 3min after the whole machine is normally ignited and started to operate for 1 min:
1. the temperature set by the user is not changed;
2. the fluctuation amount of the water inlet temperature is not more than +/-1 ℃;
3. the water flow fluctuation does not exceed the following range:
when the inflow rate is more than or equal to 10L/min, the fluctuation amount is not more than +/-1L;
when the water inlet flow is less than 10L/min, the fluctuation quantity is not more than +/-0.5L.
The flow fluctuation range is selected in relation to the gas water heater, and the selected water flow threshold and the fluctuation range thereof need to meet the normal water consumption requirement of the gas water heater, which is not limited by the invention.
Specifically, in an embodiment, after the step S103 is executed, the control method further includes the following steps:
step S107: and when the operation parameters of the gas water heater are monitored not to meet the preset operation state requirements, the control of maintaining the current working state of the segment valve is cancelled, and the step S101 is returned.
Specifically, when the target temperature or the inlet water temperature or the water flow set by the user changes, the system exits the intelligent locking state, the water temperature control method of the gas water heater in the prior art is utilized, such as PID (proportion integration differentiation) is adopted to simultaneously adjust the proportional valve and the segment valve to control the water temperature, then the working state and the outlet water temperature of the segment valve in the gas water heater are continuously monitored, and the segment valve locking judgment is carried out again until the operating parameters meet the conditions. Illustratively, the specific working process of the gas water heater is as shown in fig. 2, so that different controls of the gas water heater under different working conditions are realized, the control accuracy of the gas water heater is improved, the constant temperature effect of the outlet water temperature of the gas water heater is further ensured, and the user experience is improved. In practical application, when the switching condition of the working state of the segment valve monitored within the preset time does not meet the switching requirement of the preset segment valve, the gas water heater adopts a control mode in the prior art to realize water temperature control, and the detailed description is omitted.
By executing the steps, the control method of the gas water heater provided by the embodiment of the invention maintains the current working state of the segment valve unchanged through monitoring the working state of the segment valve in the gas water heater and according to the switching condition of the working state of the segment valve within the preset time length, so that the gas water heater burns with a fixed fire row number, and the outlet water temperature is adjusted by controlling the proportional valve, thereby avoiding the problem of outlet water temperature fluctuation caused by frequently switching the segment valve when the gas water heater encounters the conditions of gas quality change or unstable air pressure and the like, ensuring that the outlet water temperature approaches the set temperature of a user, maintaining the constant temperature effect without additionally performing constant temperature assistance, and ensuring the use experience of the user. The condition of frequent fire-switching water temperature fluctuation of the unit is judged by judging the on-off state of the section valve, and the constant temperature is realized without additional physical assistance; when the temperature of the water is frequently switched and discharged to fluctuate, the fire grate can be locked in time by controlling the working state of the sectional valve, and the fire grate can be quitted from the locking state in time when the external conditions change, so that the user experience is improved to the maximum extent.
