Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment one, the present embodiment proposes a kind of water heater display control method, as shown in Figure 1, water tank 11 structural representation for the water heater employed in the present embodiment control method, described water heater includes n the temperature sensor being successively set on from top to bottom in water tank, it puts in order the most successively is 1, 2, ..., n-1, n, as shown in Figure 2, also include and described temperature sensor 1, 2, ..., n-1, n light emitting module N1 one to one, N2 ... Nn, and the control unit (not shown) electrically connected with described temperature sensor and light emitting module respectively, described control unit is according to the detected value of each temperature sensor, control lighting and extinguishing of the light emitting module corresponding with this temperature sensor, described n is the integer more than or equal to 2.nullWater heater in the present embodiment，By being respectively provided with a light emitting module for each temperature sensor，The temperature value that control unit detects according to temperature sensor controls lighting and extinguishing of its corresponding light emitting module，Owing to temperature sensor is arranged in order in water tank in the height direction，It is for detecting the temperature of different heights of water level on water tank inner height direction，Therefore，Each light emitting module is for the temperature showing corresponding sensor place water level directly perceived，Preferably by arranging according to the spatial arrangements between the temperature sensor corresponding to each light emitting module between light emitting module，People are made more intuitively to observe the water level adding hot water at present，Either hot water is in heating process，Facilitate user to check currently and heat water level，Or during bathing，Conveniently check also surplus how high hot water water level，Great convenience is brought to use，And，Light emitting module is compared with the technology using display screen in prior art，Product cost can be greatly reduced，Light emitting module in such as the present embodiment can use LED to realize，But to quantity of information and the display effect of user's transmission，The even better than effect of display screen.
The most in the present embodiment, before control light emitting module is lighted, also include the step setting heating-up temperature Ts, temperature detected by described n temperature sensor from top to bottom is T1, T2 ... Tn, and described light emitting module is respectively N1, N2 ... Nn, in the present embodiment as a example by n=5, illustrates.The temperature of control unit Real-time Collection each temperature sensor detection, and by it compared with threshold value or setting heating-up temperature Ts, when meeting following condition, control corresponding light emitting module and light:
As T1 >=△ T11 or T1 ＞ Ts-3, N1 lights；
As T2 >=△ T12 or T2 ＞ Ts-3, and when N1 lights, N2 lights；
As T3 >=△ T13 or T3 ＞ Ts-3, and when N2 lights, N3 lights；
As T4 >=△ T14 or T4 ＞ Ts-3, and when N3 lights, N4 lights；
As T5 >=△ T15, and when N4 lights, N5 lights；
Wherein, △ T11, △ T12, △ T13, △ T14, △ T15 are threshold value set in advance.
Wherein, such as could be arranged to △ T11=△ T12=△ T13=△ T14=40 DEG C, when meeting respective sensor more than 40 DEG C, it is believed that the water of this water layer is hot water, can be with bathing.Or detection temperature is compared with Ts, owing to there is thermal loss during there is heat exchange and water flowing between different water levels, during it is therefore preferable that set compared with setting heating-up temperature Ts, slightly less than sets the value of heating-up temperature Ts as fiducial value.Water tank for leveled heating is usually hot water from tank top entrance, and temperature sensor 5 is positioned at the bottom of water tank, it is near cold water inlet, accordingly, it is capable to loss is bigger, the temperature requirement lighting the light emitting module corresponding to near-bottom temperature sensor 5 can not be the highest, otherwise the temperature of T5 is extremely difficult to set threshold value, causes and heats always, directly results in energy waste, so arranging △ T15 to be slightly less than △ T11, △ T12, △ T13 or △ T14, △ T15=35 DEG C such as can be set.
As previously described, being usually hot water for the water tank of leveled heating and enter from tank top, therefore, the more water temperature toward upper strata water level is the highest, therefore.When lighting the light emitting module being positioned at corresponding to lower floor's water level, must simultaneously meet and be positioned at the light emitting module of its upper strata water level and also light, otherwise it is likely to be misjudgment phenomenon, in order to prevent the generation of misjudgment phenomenon, it is preferably placed at the light emitting module corresponding to the water level of upper strata and lights one of them condition necessary lighted as the light emitting module being positioned at corresponding to lower floor's water level.
When meeting following condition, controller controls corresponding light emitting module and extinguishes:
As T5≤△ T25, N5 extinguishes；
As T4≤△ T24 and T4≤Ts-5, and when N5 extinguishes, N4 extinguishes；
As T3≤△ T23 and T3≤Ts-5, and when N4 extinguishes, N3 extinguishes；
As T2≤△ T22 and T2≤Ts-5, and when N3 extinguishes, N2 extinguishes；
As T1≤△ T21 and T1≤Ts-5, and when N2 extinguishes, N1 extinguishes；
Wherein, △ T21, △ T22, △ T23, △ T24, △ T25 are threshold value set in advance.
As a preferred embodiment, described control unit also includes that detection sets the step of heating water level, when setting heating water level and meeting temperature conditions, controls to stop heating.
Wherein, the described mode setting heating water level presses key assignments by water level settings, described water level settings button has N number of, it is respectively as follows: N6, N7, N8, N9, N10, with described light emitting module N1～N5 one_to_one corresponding, setting for N number of water level value, owing to each light emitting module is for the temperature showing corresponding sensor place water level directly perceived, by described water level settings button being arranged on the side of corresponding light emitting module, for inputting the water level of required heating, real reaction hot water amount to be heated, and then make water level settings the most directly perceived.
Preferably at each water level settings button respectively to having one for the display lamp indicating it to press, when control unit detects that water level settings button is pressed, the display lamp controlling the water level settings button pressed with this corresponding is lighted, and remaining display lamp does not works.
Described water level settings button is light-transmitting materials, and described display lamp is arranged on below the water level settings button that it is corresponding.
Certainly; described above is not limitation of the present invention; the present invention is also not limited to the example above, change that those skilled in the art are made in the essential scope of the present invention, retrofits, adds or replaces, and also should belong to protection scope of the present invention.
