Further, as shown in figures 1 to 6, the control method of photovoltaic double-water-tank system is further comprising the steps of：
When the water temperature of the first water tank 100 is less than the first preset temperature value and photovoltaic panel voltage is less than preset voltage value, sentence
Break now whether to belong to preset and use the water period.Wherein, preset and can artificially be set with the water period.For example preset and set with the water period
For 17:00-21:00 period.
If now belonging to the default water temperature with water period and the second water tank 200 is less than the 3rd preset temperature value, second
Electrothermal tube 203 heats the water in the second water tank 200.Wherein, the 3rd preset temperature value can artificially be set.For example the 3rd is default
Temperature value is set to 50 DEG C.
If now belonging to the default water temperature with water period and the second water tank 200 is more than or equal to the 3rd preset temperature value,
Whether the water temperature for comparing the second water tank 200 meets the temperature conditionss of pre-set user number.If the water temperature of the second water tank 200 can not
Meet the temperature conditionss of pre-set user number, then the second electrothermal tube 203 heats the water in the second water tank 200.Pre-set user number
Temperature conditionss can artificially set.For example when with water number being 2 people, the temperature conditionss of pre-set user number are the second water tank
200 water temperature is more than or equal to 60 DEG C.Similarly, when being 3 people with water number, the temperature conditionss of pre-set user number are the second water tank
200 water temperature is more than or equal to 68 DEG C；When with water number being 4 people, the temperature conditionss of pre-set user number are the water of the second water tank 200
Temperature is more than or equal to 75 DEG C.It is 1 people with water number, the temperature conditionss of pre-set user number are the second water tank 200 under default situations
Water temperature is more than or equal to 50 DEG C.
In the control method of above-mentioned photovoltaic double-water-tank system, before the water temperature of the first water tank 100 deficiency and solar energy deficiency
Putting, when with the water period, when the water temperature of the second water tank 200 is less than the 3rd preset temperature value, then the second electrothermal tube 203 is opened,
The water of the second water tank 200 is heated, to meet the hot water demand of user.Preset when the water temperature of the second water tank 200 is more than or equal to the 3rd
Temperature value, now determines whether the water temperature of the second water tank 200 meets the temperature conditionss of pre-set user number, if not,
Then the second electrothermal tube 203 is opened in time, the water of the second water tank 200 is heated, to meet the hot water demand of user.To sum up, above-mentioned light
The control method of double-water-tank system is lied prostrate by constantly discriminatory analysis, preferentially using solar energy, in the case of solar energy deficiency,
Refinement analysis, guarantee meet that the hot water demand of user is avoided as much as using civil power again.
Further, as shown in figure 1, the control method of photovoltaic double-water-tank system is further comprising the steps of：
Volume control device 406 is opened, the water temperature and the 4th temperature that master controller measures according to three-temperature sensor 407
The water temperature that sensor 408 measures, control the mixed proportion of the water of the first branch pipe 405 and the water of outlet pipe 404.
As shown in figure 4, volume control device 406 is opened, when the water temperature of the first water tank 100 is more than the 4th default water temperature value
When, master controller control first switch valve 409 is opened, second switch valve 410 is closed and the 3rd switch valve 411 is opened.Wherein,
Four default water temperature values can be taking human as setting.Such as the 4th default water temperature value be set to 40 DEG C.
As shown in figure 5, volume control device 406 is opened, when the water temperature of the first water tank 100 is less than or equal to the 4th default water temperature
During value, master controller control first switch valve 409 is opened, second switch valve 410 is opened and the 3rd switch valve 411 is closed.
In the control method of above-mentioned photovoltaic double-water-tank system, master controller and the temperature of three-temperature sensor 407 and the 4th
Sensor 408 is electrically connected with, and is believed so as to obtain the cold water water temperature information of water inlet pipe 403 and the hot water water temperature of outlet pipe 404
Breath, and then volume control device 406 is controlled, the mixing ratio of the hot water of the accurate cold water for controlling water inlet pipe 403 and outlet pipe 404
Example, using the water termostat that goes out of water end (W.E.), to improve Consumer's Experience.When the water temperature of the first water tank 100 is more than the 4th default water temperature value,
Show that the hot water of the first water tank 100 is sufficient, therefore, master controller control first switch valve 409 is opened, second switch valve 410 closes
Close and opened with the 3rd switch valve 411, the first water tank 100, the first water are flowed into from the first water inlet 102 so as to the water of water inlet pipe 403
The hot water of case 100 flows to outlet pipe 404 from the first delivery port 103, preferentially can be carried using the hot water of the first water tank 100 for user
Supplying hot water, farthest utilize solar energy.When the water temperature of the first water tank 100 is less than or equal to the 4th default water temperature value, show
The hot water of first water tank 100 deficiency, master controller controls the second heating tube to open by heating tube controller, using civil power to second
Water tank 200 water heating, while control first switch valve 409 to open, second switch valve 410 is opened and the 3rd switch valve 411 closes
Close, the second water tank 200 is flowed into from the second water inlet 201 so as to the cold water of water inlet pipe 403, the hot water in the second water tank 200 is from the
Two delivery ports 202 flow to outlet pipe 404, and then ensure the reasonable utilization of civil power, it is ensured that user with water in time, safety and conveniently.
