As shown in fig. 3, an embodiment of the present application provides a control method of a water heater, which is applied to a control device of the water heater in fig. 1 and 2, and the method includes:
s101, acquiring the water inlet temperature, the water outlet temperature, the maximum heat load and the preset water outlet flow of the water heater.
The heat load is the amount of heat released per unit time when the fuel is burned in the water heater. The maximum thermal load refers to the maximum value of the thermal load allowed under actual conditions.
The outlet water temperature can be a temperature set by a user or a default temperature of the system.
The preset water outlet flow is water flow actually required in daily life of a user, and can be water outlet flow set by the user or water outlet flow default by a system.
The temperature of the inlet water can be detected by a temperature sensor arranged on the water inlet connector.
For example, as shown in fig. 4, the current outlet water temperature 41, the preset outlet water temperature 42, the timing time 43, the preset outlet water flow 44, and the functional mode 45 of the water heater can be displayed on the display screen of the water heater. A series of buttons 46 may also be provided on the display screen of the water heater, such as function buttons, flow buttons, temperature buttons, timing buttons, switch buttons, and adjustment buttons (i.e., "+" case and "-" buttons).
When the water heater detects that a user clicks the 'on-off' key, the water heater is turned on or off. The user can also select the functional modes of the water heater by clicking a 'function' key, and when the water heater detects that the user selects one of the functional modes, the functional mode corresponding to the display screen interface is lightened. When the water heater detects that a user clicks a 'flow' key, the preset water outlet flow is set, when the user clicks a '+' key, the numerical value of the preset water outlet flow is increased, and when the user clicks a '-' key, the numerical value of the preset water outlet flow is decreased.
Similarly, when the water heater detects that the user clicks the temperature key, the water outlet temperature is set, the numerical value of the water outlet temperature is increased by clicking the plus key, and the numerical value of the water outlet temperature is reduced by clicking the minus key. When the water heater detects that a user clicks a 'timing' key, setting the timing duration, specifically, increasing the value of the timing duration by clicking a '+' key, and reducing the value of the timing duration by clicking a '-' key.
Optionally, the user may set the water heater through a remote controller configured with the water heater; or, the user sets the water heater by connecting the terminal device with the water heater.
S102, determining the maximum water outlet flow supported by the water heater according to the water inlet temperature, the water outlet temperature and the maximum heat load.
Illustratively, by
And determining the quality of the water, wherein M is the quality of the water, phi is the maximum heat load, eta is the heat efficiency, C is the specific heat of the water, and delta t is the difference value between the inlet water temperature and the outlet water temperature. Then pass through
Determining the volume of water, wherein V is the volume of water, M is the mass of water, and ρ is the density of water. It is understood that the maximum water outlet flow is the ratio of the volume of water to the time.
For example, if the inlet water temperature of the current water heater is 20 ℃, the outlet water temperature is 50 ℃, Δ t is 30 ℃, and assuming that the maximum heat load phi is 20kw, the thermal efficiency eta is 90%, and the specific heat C of water is 4.2 × 103J/(kg ℃), then the mass of water
The density rho of the water is 1000kg/m3Then the volume V of water is 0.514m3That is, 514L, the maximum water outlet flow is 514L ÷ 60min ÷ 8.6L/min.
S103, under the condition that the maximum water outlet flow supported by the water heater is larger than the preset water outlet flow, the rotating speed of a water quantity regulator motor in the water heater is regulated, so that the maximum water outlet flow allowed to be used by the water heater is equal to the preset water outlet flow.
It is understood that, when the maximum water outlet flow supported by the water heater is greater than the preset water outlet flow, it represents that the water outlet flow of the water heater is already greater than the water outlet flow actually required by the user, and in this case, energy such as water, electricity or gas is wasted. In this case, the water flow regulator is controlled by regulating the rotation speed of the water quantity regulator motor in the water heater, so that the water flow regulator changes the size of the drift diameter of the water inlet, thereby controlling the water outlet flow.
Optionally, the water flow regulator motor is controlled to operate at the maximum rotation speed under the condition that the maximum water outlet flow supported by the water heater is less than or equal to the preset water outlet flow.
For example, the preset water outlet flow of the water heater is adjusted to be 7L/min, the water outlet temperature is adjusted to be 42 ℃, and if the maximum water outlet flow determined according to the water inlet temperature, the water outlet temperature and the maximum heat load is 8.3L/min, the rotating speed of a water quantity regulator motor is adjusted to reduce the drift diameter of a water inlet interface until the water outlet flow of the water heater is 7L/min; if the maximum water outlet flow determined according to the water inlet temperature, the water outlet temperature and the maximum heat load is 6.8L/min, the rotating speed of the water quantity regulator motor is controlled to be unchanged, the drift diameter of the water inlet interface is unchanged, and the maximum water outlet flow of the water heater is still 6.8L/min.
The control method of the water heater provided by the embodiment of the application compares the maximum water outlet flow with the preset water outlet flow, because the preset water outlet flow is the water flow actually required by a user in daily life, when the maximum water outlet flow is greater than the preset water outlet flow, the maximum water outlet flow of the water heater is indicated to be greater than the water flow actually required by the user at the moment, in order to avoid energy waste, the maximum water outlet flow is equal to the preset water outlet flow by adjusting the rotating speed of a water quantity regulator motor in the water heater, on the premise of meeting the daily requirement of the user, the water quantity required to be heated is reduced, and therefore the consumption of energy is reduced. Therefore, the technical scheme provided by the embodiment of the application can realize the function of intelligently adjusting the water flow of the water heater, and reduce the use cost of a user while meeting the requirements of the user, so that the water heater is more intelligent.
Based on the embodiment shown in fig. 3, the present application further provides a control method of a water heater, as shown in fig. 5, before step S101, the method further includes:
s201, detecting the operation of selecting a first functional mode from a plurality of functional modes by a user.
The functional mode can be a mode set by a user or a default mode of the water heater.
In this embodiment of the present application, the first functional mode is configured to enable a maximum outlet flow allowed to be used by the water heater to be less than or equal to the preset outlet flow.
Optionally, the functional modes of the water heater may further include a second functional mode, and the second functional mode does not limit energy consumption of the water heater, so that the maximum water outlet flow allowed to be used by the water heater is the maximum water outlet flow supported by the water heater.
And S202, responding to the operation that a user selects a first functional mode from the plurality of functional modes, and controlling the water heater to enter the first functional mode.
Illustratively, as shown in fig. 6, the default modes of the water heater include a bathing mode, a kitchen mode and a burning mode, and the user selects the first function mode by clicking a "function" button on a display screen of the water heater. For example, when the user selects the bathing mode, the water heater enters the bathing mode.
Optionally, after the water heater enters the first function mode, steps S101-S103 are executed.
It should be noted that when the water heater detects that the user selects the second function mode (i.e., the combustion mode shown in fig. 6), the water heater directly heats after entering the second function mode, and steps S101-S103 are not executed.
Optionally, in step S101, when the first function mode of the water heater selected by the user is different, the corresponding outlet water temperature and the preset outlet water flow rate are also different accordingly.
In some embodiments, a preset water outlet flow corresponding to the first function mode is determined according to the first corresponding relationship between the first function mode and the first function mode.
Wherein, the first corresponding relationship is the corresponding relationship between the function mode and the preset water outlet flow.
For example, the correspondence between the functional mode and the preset water outlet flow rate may be as shown in table 1.
TABLE 1
| Functional modes | Preset water outlet flow |
| Bathing mode | 7L/min |
| Kitchen mode | 5L/min |
In some embodiments, the outlet water temperature corresponding to the first function mode is determined according to the first function mode and the second corresponding relationship.
Wherein, the second corresponding relation is the corresponding relation between the function mode and the outlet water temperature.
