Based on the hardware architecture of the water heater, the embodiment of the control method of the water heater is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a control method of a water heater according to the present invention, the control method of the water heater including the steps of:

In this embodiment, the execution subject is a water heater, or may be a control terminal of the water heater, such as a server or a central controller, and the control terminal is connected to the water heater wirelessly or by wire, so as to control the water heater to execute corresponding operations.
Referring to fig. 3 to 5, the water heater in this embodiment includes a heating portion 11, a water inlet pipe 12, and a water outlet pipe 13, where the heating portion 11 is communicated with the water inlet pipe 12 and the water outlet pipe 13, cold water flows from the water inlet pipe 12 to the heating portion 11, and after being heated in the heating portion 11, the cold water flows out from the water outlet pipe 13 for use by a user, so as to heat water for the user.
The water inlet pipeline 12 is provided with a water quantity adjusting part 14, the water quantity adjusting part 14 comprises a first flow channel 143 and a second flow channel 144, and at least one of the first flow channel 143 and the second flow channel 144 is provided with a water quantity adjusting device. The water inlet pipeline 12 is used for adjusting the water inlet amount through the water amount adjusting part 14, so that when a user has a large requirement on the water flow, the water inlet amount can be adjusted through the water flow adjusting part, and particularly the adjusting device is adjusted.
It can be understood that, in this embodiment, the pipe diameters of the first flow passage 143 and the second flow passage 144 may be the same or different, and specifically, in order to achieve stable flow under different water pressures, the pipe diameter of the first flow passage 143 may be set to be smaller to play a certain role in limiting the flow, for example, the pipe diameter of the first pipe is smaller than the pipe diameter of the second flow passage 144, and the water amount adjusting device is disposed on the second flow passage 144, and when the user has a smaller demand for water amount, the water amount adjusting device may be controlled to close the second flow passage 144, so that the second flow passage 144 is not conducted, and cold water enters only through the first flow passage 143 with a smaller pipe diameter, so as to reduce the water amount, and the water flow is smaller based on the fact that the first flow passage 143 is connected with a throttle. When the water demand of the user is large, the water quantity adjusting device opens the second flow passage 144, cold water enters through the first flow passage 143 and the second flow passage 144, and the water flow is large.
Alternatively, referring to fig. 4 and 5, the water amount adjusting devices are respectively disposed on the first flow passage 143 and the second flow passage 144, wherein the water amount adjusting device disposed on the first flow passage 143 is a throttle valve 141; the water amount adjusting means on the second flow path 144 is the cut-off valve 142. In this way, when the user has a small demand for water, the water amount adjusting device closes the flow rate of the second flow passage 144, and cold water can only be fed from the first flow passage 143, thereby reducing the water amount, and the water flow rate is smaller based on the throttling of the first flow passage 143. When the water demand of the user is large, the water quantity adjusting device opens the flow of the second flow passage 144, cold water enters through the first flow passage 143 and the second flow passage 144, and the water flow is large.
It should be noted that the throttle valve 141 in this embodiment includes one of a capillary, a restrictor ring, and a memory alloy. The water inlet is realized by arranging the two flow passages, the flow is limited in one flow passage, and the flow is timely throttled in one flow passage, so that the control on the water flow under different use scenes can be met, and the water inlet flow regulating device is simple in structure, easy to install and low in cost.
The water usage mode in this embodiment includes at least one of a comfort mode and an energy saving mode, and the comfort mode corresponds to a target water usage amount that is greater than a target water usage amount in the energy saving mode. The application scenes corresponding to the comfort mode include, but are not limited to, the following scenes: such as shower scenes, bathing scenes, surge scenes, and the like. The application scenarios corresponding to the energy saving mode include, but are not limited to, the following scenarios: such as ECO scenario (Ecology Optimization), hand washing scenario, kitchen scenario, etc. When scenes such as showering and bathing are performed, the larger the water quantity output by the water heater, the more comfortable the user is, the more the use effect of the water heater can be improved, and when hands, vegetables and dishes are washed in a kitchen, the less the demand of the user on the water quantity is, the smaller the water quantity output by the water heater is, the more water, electricity, gas and other energy sources are saved.
In this embodiment, the water usage mode switching instruction may be triggered when an operation is performed based on a control panel provided on the water heater, or may be triggered when an operation is performed based on a remote controller connected to the water heater, for example, it is detected that a user triggers a water usage mode switching operation based on the control panel of the water heater, or it is determined that the water usage mode switching operation is detected when a water usage mode selection operation sent by the user based on the remote controller is received. Or the water consumption mode switching instruction can be automatically triggered in the using process of a user, for example, a processor of the water heater intelligently learns the water consumption mode corresponding to each water consumption position, for example, the water consumption mode corresponding to a kitchen is an energy-saving mode, the water consumption mode corresponding to a bathroom is comfortable, and the like, and based on the fact that the opening position of the water heater when the user uses water is different from the previous water consumption position, the water consumption mode switching instruction is sent based on the current water consumption position, so that the water heater detects the water consumption mode switching instruction; or if the total power of the household appliance master gate is detected to be larger than the rated total power and the current water consumption mode is the comfortable mode, automatically sending a water consumption mode switching instruction for switching to the energy-saving mode, and thus, the water heater detects the water consumption mode switching.
After the water heater detects the water use mode switching instruction, a target water use mode corresponding to the water use mode switching instruction is obtained, and a target water quantity corresponding to the target water use mode is obtained based on the mapping relation between the water use mode and the target water inflow. For example, when the water usage mode is the comfort mode, the target water usage amount corresponding to the comfort mode is the large water usage amount, and when the water usage mode is the energy saving mode, the target water usage amount corresponding to the energy saving mode is the small water usage amount, in this embodiment, by setting the preset water amount as the critical value between the large water usage amount and the small water usage amount, when the specific target water usage amount is greater than the preset water amount, it is determined that the mode corresponding to the target water usage amount is the large water usage amount mode, and when the target water usage amount is less than the preset water amount, it is determined that the mode corresponding to the target water usage amount is the small water usage amount mode.
And controlling the water quantity adjusting device to adjust the water inflow of the water inlet pipeline according to the target water quantity. If the target water amount is larger than the preset water amount, correspondingly adjusting the water amount adjusting device to increase the water inflow of the water inlet pipeline; if the target water quantity is smaller than the preset water quantity, the water quantity adjusting device is correspondingly adjusted to reduce the water inflow of the water inlet pipeline, and the purpose of adjusting the water inflow according to the requirement of the water use mode is achieved.
Specifically, the water amount adjusting device in this embodiment is disposed in the second flow channel, and the water amount adjusting device is a stop valve, and the stop valve is used to stop or open the second flow channel to adjust the water inflow of the whole water amount adjusting device. The step of controlling the water quantity adjusting device to adjust the water inlet quantity of the water inlet pipeline according to the target water quantity comprises the following steps:
when the target water inflow is larger than the preset water inflow, namely the target water use mode requires a larger water amount, the stop valve is controlled to be powered off to conduct the second flow channel, and at the moment, the first flow channel and the second flow channel can both feed water, so that the water inflow is increased, and the water outflow is increased;
when the target water inflow is smaller than the preset water inflow, namely the water demand of the target water use mode is smaller, the stop valve is controlled to be electrified to close the second flow channel, at the moment, the first flow channel enters water, the second flow channel stops water entering, and therefore the water inflow is reduced, and therefore the water outflow is reduced. And controlling the stop valve to power off until the user shuts down.
In this embodiment, a normally open state of the shutoff valve is taken as an example, the normally open state is that the shutoff valve conducts the second flow channel when power is off, please refer to fig. 3, the shutoff valve 142 includes a blocking part 1422 and a driving part 1421 for driving the blocking part 1422 to move, the blocking part 1422 is installed in the valve body and can move between an open position and a closed position of the second flow channel 144, when the shutoff valve 142 is powered, the driving part 1421 drives the blocking part 1422 to move to the closed position of the second flow channel 144 to close the second flow channel 144, and when the shutoff valve 142 is not powered, the blocking part 1422 moves to the open position of the second flow channel 144 under the action of water pressure.
In the present embodiment, the stop valve 142 controls the driving part 1421 to drive the stopping part 1422 by using an electromagnetic induction principle, specifically, when the driving part 1421 is energized, the driving part 1421 is moved toward the stopping part 1422 by an electromagnetic attraction force to press the stopping part 1422, and the stopping part 1422 is stopped at the closing position of the second flow channel 144 to close the second flow channel 144 because the force applied by the driving part 1421 is opposite to the force applied by the water pressure and is greater than the water pressure by the force applied by the driving part 1421; when the driving part 1421 is powered off, the driving part 1421 is not subjected to an adsorption force, and moves away from the direction of the stop part 1422 to reset, when water enters the water quantity regulating valve, the water applies a pressure to the stop part 1422, the stop part 1422 moves to the opening position of the second flow channel 144, and the water can flow through the second flow channel 144, so that the stop valve 142 is simple in structure, easy to implement, and greatly saves cost compared with other regulating devices.
The water heater of the embodiment is provided with multiple water use modes, the water consumption that different water use modes correspond is different, combines to set up water regulation portion on the water inlet pipeline and adjusts the inflow, controls based on the water use mode of current operation water regulation portion adjusts the inflow, realizes having different discharge under different modes, and intelligent control discharge satisfies the user to the requirement of water consumption in different use scenes, and is energy-conserving comfortable again, improves the result of use of water heater. The water quantity adjusting part comprises a first flow channel and a second flow channel, and the water quantity of the water quantity adjusting part is adjusted by arranging the water quantity adjusting device in at least one flow channel, so that the structure is simple, and the production cost is low.
Furthermore, when the water consumption is adjusted, the fire adjustment of the gas water heater is combined, so that the water temperature can be kept within the temperature range required by a user in different modes, and a better energy-saving effect is achieved.
Referring to fig. 6 in detail, fig. 6 is a second embodiment of the control method of a water heater according to the present invention, and this embodiment is based on the first embodiment, and specifically, after the step of controlling the water quantity regulating device to regulate the water inlet quantity of the water inlet pipeline according to the target water quantity, the method further includes:
step S40, acquiring target water temperature and inlet water temperature;
step S50, determining a proportional value of a gas proportional valve according to the target water temperature, the inlet water temperature and the target water inlet amount;
and step S60, adjusting the gas proportional valve according to the proportional value.
It can be understood that, with continued reference to fig. 3 to 5, the heating part 11 in this embodiment includes a burner 111 and a heat exchanger 112, the burner 111 is located below the heat exchanger 112, the burner 111 is connected to a gas inlet, the heat exchanger 112 is connected to the water inlet pipe 12, water enters from a water inlet of the water inlet pipe 12, enters the heat exchanger 112 after the amount of water is adjusted by the water amount adjusting part 14, the burner 111 heats the heat exchanger 112, and water in the heat exchanger 112 exchanges heat with the plate heat exchanger 112 and then is discharged from the water outlet pipe 13, so that heating and use of water are completed. The combustor comprises a gas proportional valve, and the gas proportional valve is used for adjusting the gas inlet proportion of gas so as to adjust firepower.
In this embodiment, the target water temperature is a water temperature required by a user, and the inlet water temperature is an inlet water temperature at the water inlet of the current water heater. The gas proportional valve is determined according to the target water temperature, the inlet water temperature and the target water inflow, the proportional value of the gas proportional valve is determined by combining the corresponding target water inflow under the current target mode, the proportional value of the gas proportional valve is further adjusted, the water inflow and the gas proportion are combined and adjusted, energy is saved, the requirements of a user on the water quantity and the temperature of water can be met, and the using effect of the water heater is better.
It can be understood that the target water temperature may be set by a user through a control panel or a remote controller of the water heater, and in order to achieve a finer and more intelligent heating effect, the target water temperature may also be automatically obtained, for example, the target water temperature may correspond to a target water usage mode one by one, so that after the target water usage mode is determined, the target water temperature may be determined according to the target water usage mode, or the target water temperature may also correspond to the user one by one, for example, a user information recognition device such as a fingerprint collector or a camera is provided on the water heater, so that the target water temperature may be determined according to a water usage user; or, the target water temperature may also correspond to the water usage mode and the users one to one, like the water usage mode, the water temperatures required by different users are different, and after the target water usage mode is determined, the corresponding target water temperature in the target water usage mode is determined according to the user. Or the target water temperature corresponds to the water use position one by one, for example, the water temperature corresponding to kitchen water is low, or the water temperature of hand washing water is relatively high, and the target water temperature can be determined according to the water use position. Or after determining the target water usage pattern, determining the water usage temperature in the pattern based on the water usage location.
Further, referring to fig. 7, if the target water usage mode is the comfort mode, that is, the target water inflow is a large water inflow, in order to prolong the service life of the water heater, the water heater is prevented from being damaged due to long-time overload operation. In this way, a third embodiment is provided based on the second embodiment, in this embodiment, before the step of determining the proportional value of the gas proportional valve according to the target water temperature, the incoming water temperature and the target water inflow, and after the step of obtaining the target water temperature and the incoming water temperature, the method further includes:
step S70, if the target water inflow is larger than the preset water inflow, calculating a target heating load according to the target water temperature, the inlet water temperature and the target water inflow;
and step S80, controlling the stop valve to be electrified to close the second flow passage and update the target water inflow by the water inflow after the second flow passage is closed when the target heating load is detected to be larger than the rated load.
That is, when the target water inflow corresponding to the target water usage mode is the large water usage mode, if the proportional value of the gas proportional valve is directly calculated according to the target water inflow, the target temperature and the water inlet temperature, the water heater may run under an overload condition, especially in winter, when the water inlet temperature is low. Therefore, in this embodiment, when it is determined that the target water inflow is greater than the factor and the water inflow, a target heating load is calculated according to the target water temperature, the inlet water temperature, and the target water inflow, specifically, a required heating load is calculated according to energy required to make the target water inflow reach the target water temperature from the current inlet water temperature, and if the target heating load is greater than a rated load, it indicates that the water heater is in an overload operation, and even the overload operation does not reach the target water temperature, so that the stop valve is controlled to be powered on at this time to close the second flow channel, and the water inflow is reduced, thereby reducing the heating load. If the target heating load is less than or equal to the rated load, the water heater does not run in an overload mode, and the water heater can be kept running in the current high water mode, namely the stop valve is controlled to be kept in the power-off state continuously.
After the second flow channel is closed, the target water inflow is updated by the aid of the water inflow after the second flow channel is closed, so that the water heater determines a proportional value of a gas proportional valve according to the target water temperature, the inlet water temperature and the updated target water inflow, and the gas proportional valve is adjusted more accurately.
It can be understood that, if it is detected that the target heating load is greater than the rated load, the stop valve is controlled to be powered on to keep the stop valve in the powered-on state after the second flow channel is closed until a user turns off the water heater, or a mode switching command is detected again, and then the stop valve is adjusted according to a target water usage mode corresponding to the mode switching command.
Or in a fourth embodiment, referring to fig. 8, based on the third embodiment, after the step of controlling the cut-off valve to be powered on to close the second flow passage and update the target water inflow with the water inflow after closing the second flow passage when the target heating load is greater than the rated load, the present embodiment further includes:
and step S90, when the target heating load is smaller than the rated load, controlling the stop valve to be powered off to open the second flow passage, and updating the target water inflow by the water inflow after the second flow passage is opened.
