Described heating mode rate-determining steps S4, controls the heated mould of water heater according to described result of the comparison
The switching of formula.Specifically, if the described heat time more than described remaining time, then shows water heater
Operation occurs abnormal, it is impossible to add the reservation water moment hankering setting in reservation by water heating according to user
To reservation coolant-temperature gage, then for ensure user can according to book setting with water moment and reservation water
Temperature uses hot water, in heating mode rate-determining steps S4, is switched to quickly by the heating mode of water heater
Heating mode, with the hot water in heating water tank as early as possible.Otherwise, if the described heat time is equal to described
Remaining time, then show water heater normal operation, current heating mode can be maintained.Further,
If the described heat time is less than described remaining time, then show that water heater heating is very fast, for saving energy
Source can be switched to energy saver mode.
Preferably, after the temperature of water raises predetermined temperature in water tank, it is again started up described calculating and ratio
Relatively operate, and further, if the heat time again calculated is equal to the residue again calculated
Between, then show water heater normal operation, in the most described heating mode rate-determining steps 4, control water heater
Heating system maintain current heating mode.Further, if the heat time again calculated
Less than the remaining time again calculated, then show that the firing rate of water heater is accelerated, for saving the energy,
Heating mode can be switched to heating mode before this from current heating mode.
Described predetermined water temperature can set according to environment temperature and described reservation coolant-temperature gage, can by with
Family manually sets on the control panel of water heater.Owing to the reservation coolant-temperature gage of user is usually 42-45
DEG C scope, and in the case of the use environment temperature setting water heater is usually 20-30 DEG C, then this is pre-
Determine the selection of water temperature, such as, be set as 40 DEG C.Herein, it should be noted that the setting of temperatures above
With select to be merely exemplary, but, present invention is obviously not limited to this, the technology of art
Personnel can be set according to the service condition of water heater.Being 40 DEG C with described reservation water temperature below is
Example, illustrates a preferred specific embodiment of the flow process of the control method of the present invention in conjunction with Fig. 5.
If the current water temperature of water is Tw in water-heater water tank, reservation coolant-temperature gage is Ts (Ts > 45 DEG C),
Current time is T, and the reservation water moment is Tt, and the heat time is t.
First user utilizes, such as the water moment is used in the key-press input reservation on the control panel of water heater
With reservation coolant-temperature gage, water heater starts afterwards, and its heating system begins to warm up the water in water tank.Water
Temperature monitoring means 2 starts to detect the current water temperature Tw of water in water tank.Arithmetic element 3 receives this current water
Temperature Tw, and compare the size of itself and described predetermined water temperature.When described reservation water temperature is equal to 40 DEG C, fortune
Calculate unit 3 and calculate the heat time t heated the water to needed for described reservation coolant-temperature gage Ts, and compare
This heat time t and described reservation water moment Tt deducts the remaining time of current time T gained (i.e.
Tt-T) size.
If the described heat time is more than described remaining time, then heating mode control unit 4 output control
System instruction, switches to quick heating mode by the heating mode of water heater, otherwise, if described heating
Time is equal to described remaining time, then show water heater normal operation, can maintain current heating mode.
Further, if the described heat time less than described remaining time, then shows that water heater heating is very fast,
Energy saver mode can be switched to for saving the energy.
It follows that after being detected that water temperature raises predetermined number of degrees with respect by water temperature detection unit 2, count again
Calculate and the water in water tank is heated to the heat time needed for described reservation coolant-temperature gage Ts from current water temperature
(for the sake of difference, be expressed as t '), and judge that whether described heat time t ' is more than described residue
Time (is expressed as Tt '-T '), and if being, the most described heating mode control unit 4 controls hot water
The heating system of device maintains current heating mode.If no, then heating mode control unit 4 is permissible
The heating mode of water heater is switched to heating mode before this from current heating mode.
Above in association with accompanying drawing, the water heater of the present invention and control device thereof are described in detail.According to
The solution of the present invention, it is possible to by calculating when the water in water tank is heated to reservation water by current time
Carve the time being actually needed, it is thus understood that whether the operation conditions of the heating assembly of water heater is in normally
State, thus when abnormal conditions occurs in water heater operation, can be in time by switching the heating of water heater
Pattern, it is ensured that water heater uses water the reservation use water moment that user sets, thus improves making of user
With experience.And further, after water heater is switched to quick mode, by again calculating from working as
Water in water tank is heated to time that the reservation water moment is actually needed less than remaining time by the front moment
In the case of, control water heater and be switched to former heating mode, thus reach to save the purpose of the energy.
