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.
It is understood that the water heater in the present embodiment may include, but is not limited to, a gas water heater or a wall-hanging stove, and the like, and is not limited thereto.
Referring to fig. 3, the water heater 1 includes a heating portion 11, a water inlet pipe 12 and a water outlet pipe 13, the heating portion 11 is communicated with the water inlet pipe 12 and the water outlet pipe 13, so that cold water flows into the heating portion 11 through the water inlet pipe 12, and flows out of the water outlet pipe 13 after being heated in the heating portion 11, so as to be used by a user, thereby heating water.
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 (not marked in the figure) and a second flow channel (not marked in the figure), and at least one of the first flow channel and the second flow channel is provided with a water quantity adjusting device for adjusting the water flow quantity of the first flow channel and/or the second flow channel. 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 water amount adjusting device is adjusted.
It can be understood that, in this embodiment, the pipe diameters of the first flow passage and the second flow passage may be the same or different, and specifically, in order to achieve steady flow under different water pressures, the pipe diameter of the first flow passage may be set to be smaller to play a certain role in limiting flow, for example, the pipe diameter of the first pipe is smaller than the pipe diameter of the second flow passage, and the water amount adjusting device is disposed on the second flow passage, when a user has a small demand for water amount, the water amount adjusting device may be controlled to close the second flow passage, so that the second flow passage is not conducted, cold water enters only through the first flow passage with a small pipe diameter, so as to reduce the water amount, and based on the fact that the first flow passage is connected with a throttle, the water flow is smaller. When the water demand of a user is large, the water quantity adjusting device opens the second flow channel, cold water enters through the first flow channel and the second flow channel, and the water flow is large.
Or, the water amount regulating devices are arranged on the first flow passage and the second flow passage, wherein the water amount regulating device on the first flow passage is a throttle valve 141; the water amount adjusting means on the second flow path is the cut-off valve 142. So, when the user is less to the water demand, water regulation apparatus closes the flow of second runner, and cold water can only be followed first runner is intake, reduces the water yield, and based on first runner throttle, water flow is littleer. When the water demand of a user is large, the water quantity adjusting device opens the flow of the second flow channel, cold water enters through the first flow channel and the second flow channel, 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.
In an embodiment, the water usage mode switching command in S10 may be triggered when the operation is performed based on a control panel provided on the water heater, or may be triggered when the operation is performed based on a remote controller connected to the water heater, for example, when it is detected that a user triggers the water usage mode switching operation based on the control panel of the water heater, or when it is received that the user selects the water usage mode sent by the remote controller, it is determined that the water usage mode switching operation is detected. 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, such as the water consumption mode corresponding to a kitchen, and the water consumption mode corresponding to a bathroom, and based on the fact that the opening position is different from the previous water consumption position when the user uses water, the water consumption mode switching instruction is sent based on the current water consumption position, so that the water consumption mode switching instruction is detected by the water heater; 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 using mode is the water using mode corresponding to the bathroom, automatically sending a water using mode switching instruction for switching to the water using mode corresponding to the kitchen, and thus, the water heater detects the water using mode switching.
Furthermore, the water using mode of the water heater comprises a first water using mode and a second water using mode, and the water inflow corresponding to the first water using mode is larger than the water inflow corresponding to the second water using mode.
Specifically, the first water mode is a comfort mode, and the second water mode is an energy saving mode, that is, the water usage mode of the water heater in this embodiment includes a comfort mode and an energy saving mode, and the target water usage amount corresponding to the comfort mode is greater than the 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.
Further, after a first water mode corresponding to the water usage mode switching instruction is obtained, a target water inflow temperature corresponding to the first water mode and an actual water inflow temperature of the water inlet pipe are obtained, and the water usage mode of the water heater is determined based on a mapping relation between the target water inflow temperature and the actual water inflow temperature of the water inlet pipe. Because the output thermal power of water heater is less, and the big water consumption of the inflow that first water mode corresponds, at this moment, need judge earlier whether the actual temperature of intaking of inlet channel can reach the target temperature of intaking, wherein, the actual temperature of intaking is based on the water heater the temperature that needs reach under the first water mode, the target temperature of intaking is the temperature that the user set for, promptly the actual temperature of intaking of inlet channel is less than during the target temperature of intaking, then control the water heater switch to the little water consumption mode that the second water mode corresponds, at this moment, according to the inflow control of second water mode water quantity adjusting device adjusts the inflow of inlet channel to make water heater economize on water, energy-conservation.
Specifically, because the output thermal power of the water heater is small, that is, when the water inflow of the water heater is adjusted according to the water inflow corresponding to the second water mode, it is determined whether the water heater is in a heating combustion state, if the water heater is in the heating combustion state, it is indicated that the water heater starts heating, and the water inflow corresponding to the second water mode is a small water consumption, the output thermal power of the water heater is enough to heat the water inflow corresponding to the second water mode to the temperature set by the user, that is, at this time, the step of adjusting the water inflow of the water inlet pipeline by the water amount adjusting device according to the water inflow of the second water mode can be executed; if the water heater is not in a heating combustion state, the water heater is not started, the output heat power of the water heater does not heat the water inflow corresponding to the second water mode to the temperature set by a user, at the moment, the water inflow of the first water mode is controlled by the water quantity regulating device to regulate the water inflow of the water inlet pipeline, and when the water inlet time corresponding to the first water mode is longer than or equal to the preset time, the step of regulating the water inflow of the water inlet pipeline by the water quantity regulating device according to the water inflow of the second water mode is executed, namely, under the condition that the heating time of the water heater is long, the water is fed into the water inlet pipeline through the water inflow corresponding to the first water mode, and the water is fed into the water inlet pipeline through the water inflow corresponding to the second water mode after the cold water in the water inlet pipeline reaches a certain amount, so that the temperature of the water in the water inlet pipeline is relatively uniform.
Alternatively, the preset time may be a time set by a user, such as: 10s, etc., and is not limited herein.
Further, since the water heater described above is fed with water in the first water mode, and the water inflow corresponding to the first water mode is greater than the water inflow corresponding to the second water mode, when the water quantity adjusting device is controlled to adjust the water inflow of the water inlet pipeline according to the target water quantity, the water quantity adjusting device is adjusted correspondingly, so as to reduce the water inflow of the water inlet pipeline, and achieve the purpose of adjusting the water inflow according to the requirement of the second water mode.
It can be understood that, between the steps of obtaining the first water mode corresponding to the water usage mode switching instruction and obtaining the target inlet water temperature corresponding to the first water mode, the water quantity adjusting device may be controlled to adjust the inlet water quantity of the inlet water pipeline according to the inlet water quantity of the first water mode, that is, the water quantity adjusting device may be adjusted correspondingly to increase the inlet water quantity of the inlet water pipeline.
And when the actual water inlet temperature of the water inlet pipeline is higher than the target water inlet temperature, determining that the output thermal power of the water heater can meet the condition that the water inlet temperature of the water inlet amount corresponding to the first water mode reaches the target water inlet temperature, and at the moment, controlling the water amount regulating device to regulate the water inlet amount of the water inlet pipeline according to the water inlet amount of the first water mode.
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 of the water inlet pipeline by the water quantity adjusting device according to the water inlet quantity of the second water use mode comprises the following steps of:
controlling the stop valve to be powered off to conduct the second flow channel, wherein both the first flow channel and the second flow channel can feed water, so that the water inflow is increased, and the water outflow is increased;
the step of controlling the water quantity adjusting device to adjust the water inlet quantity of the water inlet pipeline according to the water inlet quantity of the first water using mode comprises the following steps of:
and controlling the cut-off valve to be electrified so as to close the second flow passage, wherein at the moment, the first flow passage enters water, and the second flow passage stops water inlet, so that the water inlet amount is reduced, and the water outlet amount is reduced. And controlling the stop valve to power off until the user shuts down.
In the embodiment of the invention, the control method of the water heater obtains the first water mode corresponding to the water use mode switching instruction and obtains the target water inlet temperature corresponding to the first water mode, and when the actual water inlet temperature of the water inlet pipeline is lower than the target water inlet temperature, the water quantity regulating device is controlled to regulate the water inlet quantity of the water inlet pipeline according to the water inlet quantity of the second water mode, wherein the water inlet quantity corresponding to the first water mode is larger than the water inlet quantity corresponding to the second water mode. Therefore, the technical scheme provided by the invention can adjust the water inflow of the water heater through the relation between the actual water inflow temperature and the target water inflow temperature corresponding to the first water mode, so that the output heat power of the water heater heats the water in the water inlet pipeline to the temperature set by a user, and the water outflow temperature of the water heater reaches the requirement of the user, thereby meeting the bathing requirement of the user on larger flow.
Further, a gas regulating valve is arranged between the water inlet pipeline of the water heater and the water outlet pipeline of the water heater. When adjusting the water consumption, combine gas heater's firepower to adjust for the water temperature homoenergetic keeps in user demand temperature range under different modes, still reaches better energy-conserving effect simultaneously, if when the water consumption is big, increases the firepower, so that the temperature reaches the required temperature of user fast, and the water consumption is hour, avoids the gas extravagant, reduces firepower etc. wherein, increases in this embodiment or reduces the firepower and can adjust through adjusting the gas.
Referring to fig. 4, fig. 4 is a second embodiment of the control method of the 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 of the water inlet pipeline by the water quantity adjusting device according to the water inlet quantity of the second water mode, the control method of the water heater further includes:
s40, acquiring the actual water inflow of the water inlet pipeline;
