Embodiment two
Fig. 2 is the method for work schematic diagram of a kind of thick-film electric water heater embodiment one initial heating pattern.As in figure 2 it is shown, described first water temperature probe 80 set operating temperature as Ta, described second water temperature probe 81 set operating temperature as Tb, the numerical value of described Ta and Tb can be adjusted；The duty of the first water temperature probe 80 and the second water temperature probe 81 is regulated and controls by arranging the quantity difference between numerical value and Ta, Tb of the numerical value of Ta, Tb, described first water temperature probe 80 and described second water temperature probe 81 all can control heater 1 and work, this heater 1 makes the temperature of water in water storage bag 2 raise, thus adjusting the outlet 6a leaving water temperature of water pipe 6.
Described initial heating pattern carrying out practically is as follows: described first water temperature probe 80 sets operating temperature as Ta, described second water temperature pop one's head in 81 set operating temperature as Tb=Ta-20-30；In initialization process, monitoring temperature Ta ', the Tb ' of described first water temperature probe 80 and described second water temperature probe 81 are respectively lower than setting work temperature a, the Tb of its correspondence, and now described second water temperature 81 priority acccess control heaters 1 of popping one's head in work；The heating of this heater 1 stops heating to the monitoring temperature Ta ' to Ta of described first water temperature probe 80；
In the present embodiment, described Ta is 80 DEG C, described Tb=55 DEG C, utility model people finds in actual test process, after stopping heating, due to the waste heat effect of heater, the temperature Ta ' that described first water temperature probe 80 monitors can rise about 3 degree on the basis of the operating temperature set, so showing that its temperature is 83 DEG C in an embodiment.
Additionally, this kind of especially suitable winter mode of mode of operation, namely using in situation in winter, effect becomes apparent from.
Embodiment three
Fig. 3 is the method for work schematic diagram of a kind of thick-film electric water heater embodiment dual-purpose water heating mode.As shown in Figure 3, after initial heating pattern, user's water, first described second water temperature probe 81 monitors its monitoring temperature Tb ' and declines, when described Tb ' is down to below Tb-5, and described first water temperature probe 80 monitoring temperature Ta ' less than Ta+5 time, described second water temperature 81 priority acccess control heaters 1 of popping one's head in work；Additionally, this kind of mode of operation especially suitable spring, autumn and summer mode, using under this kind of environment, effect becomes apparent from.
Embodiment four
Fig. 4 is the method for work schematic diagram of a kind of thick-film electric water heater embodiment three holding mode.As shown in Figure 4, after initial heating pattern, user is without water, entering keeping warm mode, now the monitoring temperature Ta ' of described first water temperature probe 80 declines, due to the effect of mixed flow, the monitoring temperature Tb ' of described second water temperature probe 81 sets work temperature b higher than it, now, 80 priority acccess control heaters 1 work of popping one's head in of described first water temperature carry out concurrent heating, and described first water temperature probe 80 control heaters 1 repeatedly work and make the water temperature in water storage bag 2 basically identical with the work temperature a of setting.After warm pattern, user's water, described second water temperature probe 81 monitors water temperature drop, if now its temperature Tb ' monitored is lower than the work temperature b of its setting, now described second water temperature probe 81 control heater 1 work carries out concurrent heating；If additional heat is more than described water outlet heat, water temperature will raise until the monitoring temperature Ta ' of described first water temperature probe 80 reaches its design temperature Ta+5, now the second water temperature probe 81 stopping heating work.
Embodiment five
Fig. 5 is the method for work schematic diagram of a kind of thick-film electric water heater embodiment four holding mode.As shown in Figure 5, described holding mode also includes: after warm pattern, user's water, and described second water temperature probe 81 monitors water temperature drop, if now its temperature Tb ' monitored is lower than the work temperature b of its setting, now described second water temperature probe 81 control heater 1 works；Now the monitoring temperature Ta ' of described first water temperature probe 80 is higher than Ta+3 and lower than Ta+5, and the monitoring temperature Tb ' of described second water temperature probe 81 is lower than Tb-2 and higher than Tb-5, if user continues routine water, now increase by a Conditions Temperature C, namely when the monitoring temperature of the second water temperature probe 81 is lower than Tb-C, described second water temperature probe 81 control heater 1 works, monitoring temperature Tb ' to described second water temperature probe 81 quits work when reaching Tb, and described first water temperature probe 80 monitoring temperature Ta ' less than Ta+5, can namely be controlled heater 1 continuous operation by the second water temperature probe 81 and reach its setting work temperature b to described second water temperature probe 81.
In the present embodiment, C value is 10 DEG C, because the temperature of its water inlet is likely to relatively low, when being in fact winter, second water temperature probe 81 can pre-cooling concurrent heating, it is ensured that the concurrent heating amount of heater, it is possible to solve that the temperature into cold water is relatively low causes that the second water temperature is popped one's head in not up to during lower than its design temperature 5 DEG C, the problem that second water temperature probe can not control heater work, it is possible in advance the water in water storage bag is heated.
Embodiment six
Fig. 6 is the method for work schematic diagram of a kind of unconventional water-use model of thick-film electric water heater embodiment five.As shown in Figure 6, unconventional water-use model: user directly puts high-temperature-hot-water, owing to intake pressure is big, water mixed flow in water storage bag 2, now the monitoring temperature Ta ' of described first water temperature probe 80 is down to below Ta-2, the monitoring temperature Tb ' of described second water temperature probe 81 is higher than the work temperature b of its setting, and now the first water temperature probe 80 control heater 1 heats.Described Ta=70-80 DEG C.Described C is 5-10 DEG C.
In embodiment two to embodiment six, described Ta is 80 DEG C, described Tb=55 DEG C, in embodiment, 80 DEG C, 55 DEG C and 80 DEG C are only preferred value, not representing this numerical value is fixed numbers, and those skilled in the art can be changed according to actual service condition and adjust within the specific limits, as long as utilize what this principle was operated to belong to the technical solution of the utility model.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
