Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application 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 present application and are not intended to limit the present application.
In one embodiment, a water outlet control method for a wall-mounted boiler is provided, and the wall-mounted boiler can be a plate-type wall-mounted boiler. As shown in fig. 1, the method includes:
step S110: when the wall-mounted boiler performs heating combustion, whether preset domestic hot water demand conditions are met or not is detected.
Specifically, when the wall-mounted boiler performs heating combustion, whether preset domestic hot water demand conditions are met or not can be detected through a controller of the wall-mounted boiler. After the wall-mounted boiler is powered on and started, when a user inputs a heating combustion instruction, a heating combustion function is executed, the three-way valve is switched to the heating combustion side pipeline, meanwhile, control is performed according to a stored heating combustion control program, heating is executed according to normal heating combustion logic, for example, the combustion power of the combustor is controlled according to the heating temperature set by the user, and at the moment, hot water heated by the main heat exchanger flows to the heating combustion side pipeline through the three-way valve.
The controller also monitors whether a preset domestic hot water demand condition is triggered when heating combustion water supply is executed according to normal heating combustion logic. The specific type of domestic hot water demand condition is not exclusive, and in one embodiment, the domestic hot water demand condition includes: and detecting that the domestic hot water faucet is started or receiving a domestic hot water outlet instruction. For example, by providing a pressure sensor in the domestic hot water side pipeline, the controller determines whether the domestic hot water faucet is turned on according to a pressure value detected by the pressure sensor. And when the opening of the domestic hot water faucet is detected, judging that the domestic hot water requirement condition is met. Or, the controller can directly judge that the domestic hot water requirement condition is met when a domestic hot water outlet instruction input by a user through a setting button of the wall-mounted boiler is received. The user can select the specific mode of triggering the domestic hot water demand condition according to the actual demand, and the operation is simple and reliable.
Step S120: when the condition that the domestic hot water requirement is met is detected, the wall-mounted boiler is controlled to burn with the preset minimum power, and a switching instruction is output to the three-way valve of the wall-mounted boiler.
Wherein, the switching instruction is used for controlling the three-way valve to guide the hot water heated by the wall-mounted boiler to the domestic hot water side pipeline. When the controller detects that the domestic hot water demand condition is met, the controller controls the combustor of the wall-mounted boiler to burn with preset minimum power, outputs a switching instruction to the three-way valve of the wall-mounted boiler, and controls the three-way valve to guide the hot water heated by the wall-mounted boiler to the domestic hot water side pipeline. The specific value of the preset minimum power is not unique, specifically, the maximum combustion power and the minimum combustion power of the wall-mounted furnace can be preset, and the combustion power of the combustor needs to be between the maximum combustion power and the minimum combustion power when the wall-mounted furnace works so as to ensure the use safety of the wall-mounted furnace. Moreover, the burning power of the wall-mounted boiler during heating burning is greater than that during the water outlet of the domestic hot water, so that the heating effect is ensured, and the user is prevented from being scalded by the overhigh temperature of the domestic hot water.
Step S150: when the burning time of the wall-mounted boiler with the preset minimum power is greater than or equal to the preset time threshold, the wall-mounted boiler is controlled according to a pre-stored domestic hot water control program.
The specific value of the preset time length threshold is not unique, and can be adjusted according to actual requirements, for example, according to actual environment temperature. Specifically, the preset time threshold value can be set according to a thermal reaction time constant of a temperature sensor in the domestic hot water side pipeline, and can be selected to be 5 seconds to 15 seconds. The controller starts timing when controlling the burner of the wall-mounted boiler to burn with preset minimum power, controls according to a pre-stored domestic hot water control program when the timing duration is greater than or equal to a preset duration threshold value, and controls water outlet according to normal domestic hot water logic. For example, the combustion power of the burner is adjusted according to the temperature of domestic hot water set by the user, and the device is stopped when a temperature sensor in the domestic hot water side pipeline detects that the water temperature is higher than a set temperature.
In one embodiment, after step S110, the method further comprises: when the domestic hot water demand condition is not detected, the process returns to step S110. If the controller does not detect the domestic hot water demand condition, the controller returns to the step S110 to continue to detect, and meanwhile, the wall-hanging stove is executed according to the heating combustion logic, so that the normal heating function of the wall-hanging stove is not influenced.
Above-mentioned hanging stove goes out water control method, hot water after triggering hanging stove heating when the user triggers life hot water demand condition leads life hot water side pipeline to control hanging stove with minimum power burning until long be greater than or be equal to long predetermined time threshold value, avoid because the heat of heating side pipeline influences the temperature measurement of life hot water side pipeline and shut down, need not to put out fire and ignite again and accelerate life hot water temperature rise speed, can provide life hot water play water more fast, compare with traditional hanging stove, the convenience of use has been improved.
In one embodiment, as shown in fig. 2, after step S120 and before step S150, the method further includes step S130 and step S140.
Step S130: and receiving the outlet water temperature detected by the domestic hot water outlet water temperature sensor, and detecting whether the water temperature meets the preset domestic hot water stop condition.
Wherein, the domestic hot water outlet temperature sensor is arranged on a domestic hot water side pipeline. The outlet water temperature of the domestic hot water in the domestic hot water side pipeline is detected through the domestic hot water outlet temperature sensor, and whether the water temperature meets the preset domestic hot water stop condition or not is detected. The specific content of the domestic hot water stop condition is not unique, and in the embodiment, the domestic hot water stop condition includes that the outlet water temperature is greater than the set temperature threshold. When the controller determines that the outlet water temperature of the domestic hot water side pipeline is greater than the set temperature threshold, step S140 is executed.
Step S140: when the outlet water temperature meets the preset domestic hot water stop condition, whether the burning time of the wall-mounted boiler at the preset minimum power is greater than or equal to a preset time threshold value or not is detected.
When the controller judges that the water temperature meets the preset domestic hot water stop condition, the controller detects the burning time of the burner of the wall-mounted furnace at the preset minimum power and judges whether the burning time is greater than or equal to a preset time threshold. And when the burning time of the burner at the preset minimum power is greater than or equal to the preset time threshold, executing step S150, and starting the normal domestic hot water logic to execute the water outlet control.
Further, when the burning duration of the wall-mounted boiler at the preset minimum power is less than the preset duration threshold, it may be determined that the water outlet temperature at this time satisfies the preset domestic hot water stop condition and is caused by heat transfer of heating burning, and the step S130 is returned to continue to detect whether the water temperature satisfies the preset domestic hot water stop condition until the burning duration of the burner at the preset minimum power is greater than or equal to the preset duration threshold.
In this embodiment, when detecting that the outlet water temperature of life hot water side pipeline satisfies preset life hot water shut-down condition, change the control mode that traditional hanging stove was directly shut down to long time threshold value is reached in the burning of preset minimum power burning control hanging stove, has avoided the slow condition of life hot water temperature rise that flame-out relight leads to.
Further, in one embodiment, after step S130, the method further comprises step S160: and when the outlet water temperature does not meet the preset domestic hot water stop condition, controlling according to a prestored domestic hot water control program.
If the outlet water temperature of the domestic hot water side pipeline does not meet the domestic hot water stop condition, the controller directly executes outlet water control according to normal domestic hot water logic, for example, the combustion power of the burner is adjusted according to the domestic hot water temperature set by a user. When the outlet water temperature of the domestic hot water side pipeline does not meet the domestic hot water stop condition, the normal domestic hot water logic is directly executed according to the pre-stored domestic hot water control program, so that the outlet water temperature of the domestic hot water can be increased more quickly for the use of a user.
In order to better understand the above-mentioned wall-hanging stove water outlet control method, the following explanation is made with reference to specific embodiments.
As shown in fig. 3, in the wall-hanging stove water outlet control method provided by the present application, when the wall-hanging stove performs a heating and burning function, it is detected whether a user has a domestic water demand, and if so, the burner is controlled to burn at a minimum power, and the three-way valve is adjusted to switch the hot water heated by the wall-hanging stove from the heating and burning side pipeline to the domestic hot water side pipeline. When the burner burns with minimum power, the controller receives the outlet water temperature detected by the temperature sensor in the domestic hot water side pipeline, judges whether the outlet water temperature meets the domestic hot water stop condition or not, and if not, executes according to normal domestic hot water logic; if yes, judging whether the burning time of the burner with the minimum power is more than or equal to the preset time. The preset time can be set according to the thermal reaction time constant of the temperature sensor in the domestic hot water side pipeline, and can be selected to be 5 seconds to 15 seconds, for example.
And when the minimum power combustion duration is longer than or equal to the preset time, executing according to the normal domestic hot water logic, if the minimum power combustion duration is shorter than the preset time, determining that the outlet water temperature meets the domestic hot water shutdown condition and is caused by heat transfer of heating combustion, detecting the domestic hot water shutdown condition again until the domestic hot water shutdown condition is met and the minimum power combustion time reaches the preset time, and executing according to the normal domestic hot water logic.
