Specifically, the second duct 320 is partially located in the heat storage tank 110, and the hot water in the insulation can 500 exchanges heat with the heat storage tank 110 through the second duct 320.
Specifically, the first temperature sensor is located in the incubator 500, and is configured to detect a temperature inside the incubator 500 and send the temperature to the control module.
Specifically, the second temperature sensor is located in the water storage tank 210, and is configured to detect a temperature in the water storage tank 210 and send the temperature to the control module.

The first predetermined temperature T1 is in the range of 45 ℃ to 55 ℃, preferably 50 ℃. The first predetermined height ratio H1 is less than 5%, preferably 0%. When the temperature Tb of the heat preservation box is less than 50 ℃ and the liquid level height ratio Hb of the heat preservation box is more than 0%, cold water with low water temperature is determined to be reserved in the heat preservation box 500, if hot water is injected into the water storage box 210, cold water in the heat preservation box 500 is mixed with the hot water, and the temperature of the hot water injected into the heat preservation box 500 cannot meet the requirement of supplying heat to the heat storage box 110, so that the fourth valve 430 is firstly opened to discharge the cold water in the heat preservation box 500; until the liquid level ratio Hb of the thermal insulation box is reduced to 0%, which indicates that the cold water in the thermal insulation box 500 is drained, the fourth valve 430 is closed, the first valve 400 is opened, and the hot water in the water storage tank 210 is injected into the thermal insulation box 500. Specifically, the second preset height ratio H2 is 90% or more, preferably 95%, and when the amount of hot water in the heat insulation box 500 reaches 95% or more, the heat insulation box 500 is filled with hot water, the first valve 400 is closed, and the water storage tank 210 stops injecting hot water into the heat insulation box 500.
When the temperature Tb of the incubator is lower than the first preset temperature T1 and the liquid level ratio Hb of the incubator is lower than or equal to the first preset height ratio H1, the first valve 400 is opened, and when the liquid level ratio Hb of the incubator is higher than or equal to the second preset height ratio H2, the first valve 400 is closed. When the temperature Tb of the heat preservation box is less than 50 ℃ and the liquid level height ratio Hb of the heat preservation box is equal to 0%, cold water does not exist in the heat preservation box 500, the first valve 400 is directly opened, and hot water in the water storage tank 210 is injected into the heat preservation box 500.

When the temperature Tb of the heat preservation box is higher than 50 ℃ and the liquid level height ratio Hb of the heat preservation box is greater than 60%, hot water in the heat preservation box 500 meets the heat exchange requirement of the heat preservation box 11, at the moment, the water in the water storage box 210 meets other water requirements, and hot water is injected through the water storage box 210 when the liquid level height ratio Hb of the heat preservation box is less than or equal to 60%, so that the hot water between the solar water heater 200 and the heater 100 is balanced in a shared mode.
Specifically, in operation S200, the water return tank liquid level is also obtained, the water return tank liquid level ratio is determined, and when the water return tank liquid level ratio is greater than or equal to the fourth preset height ratio H4, the third valve 420 and the first circulation pump 800 are opened until the water return tank liquid level ratio is reduced to be less than or equal to the fifth preset height ratio H5.
Specifically, the fourth preset height ratio H4 refers to a preset height ratio when the water level in the water return tank is high and water needs to be drained from the water return tank 600; the fifth preset height ratio H5 is a safety ratio of the water level in the return tank 600, and when the water level in the return tank 600 is less than the fifth preset height ratio H5, it is unnecessary to discharge the water in the return tank 600, preferably in the range of 5% to 30%. When the liquid level ratio of the water return tank is greater than or equal to the fourth preset height ratio H4, the third valve 420 and the first circulation pump 800 are opened to return the water in the water return tank 600 to the water storage tank 210 until the liquid level ratio of the water return tank is reduced to be less than or equal to the fifth preset height ratio H5, so as to prevent the water in the water return tank 600 from being filled with water and hindering the heat exchange between the heat preservation tank 500 and the heat storage tank 110.
Specifically, the memory stores a plurality of fourth preset height ratios H4, and when the corresponding conditions are met, the fourth preset height ratios H4 obtain different values.
Specifically, when the storage tank temperature Tc is less than the second preset temperature T2, the fourth preset height ratio H4 is in the range of 70% to 90%, preferably 80%. When the temperature Tc of the water storage tank is less than 65 ℃, the temperature in the water storage tank 210 is not high, and the water is not suitable for returning to the water storage tank 210, so that the temperature of the water in the water storage tank 210 is reduced, and when the water amount in the water return tank 600 reaches more than 80%, the water in the water return tank 600 is guided back to the water storage tank 210.
Optionally, the fourth preset height ratio H4 is in the range of 70% to 90%, preferably 80%, when the holding tank temperature Tb is less than the first preset temperature T1 and the storage tank temperature Tc is less than the second preset temperature T2. When the temperature Tb of the thermal insulation box is less than 50 ℃ and the temperature Tc of the water storage tank is less than 65 ℃, the temperature in the water storage tank 210 is not high, and it is not suitable to inject water with lower temperature in the water return tank 600 into the water storage tank 210, and when the water amount in the water return tank 600 reaches more than 80%, the water in the water return tank 600 is guided back into the water storage tank 210.
Specifically, in the operation of step S200, an ultraviolet intensity value is also obtained, and when the ultraviolet intensity value is smaller than the first preset intensity value, the fourth preset height ratio H4 is in the range of 40% to 90%, preferably 80%;
when the ultraviolet intensity value is greater than the second preset intensity value, the fourth preset height ratio H4 is in the range of 10% to 30%, preferably 20%;
the first preset intensity value is smaller than the second preset intensity value.
Specifically, when the ultraviolet intensity value is smaller than the first preset intensity value, it means that the ultraviolet intensity received by the solar water heater is not high, the speed of converting the solar water heater into hot water is not high, or the temperature of converting the solar water heater into hot water is not high. As long as the ultraviolet intensity value is smaller than the first preset intensity value, the fourth preset height ratio H4 is 80% regardless of the temperature of the heat insulation box 500 and the water storage tank 210, so as to prevent the water in the water return tank 600 from flowing back into the water storage tank 210 to further slow down the water temperature rise.
Specifically, when the ultraviolet intensity value is greater than the second preset intensity value, it means that the ultraviolet intensity received by the solar water heater is high, the speed of converting the solar water heater into hot water is high, or the temperature of converting the solar water into hot water is high. As long as the ultraviolet intensity value is greater than the first preset intensity value, no matter what the temperature of the heat preservation box 500 and the temperature of the water storage tank 210 are, the value of the fourth preset height ratio H4 is 20%, so that the water reserved in the water return tank 600 is guided back into the water storage tank 210 when the water amount exceeds 20%, and the water temperature in the water storage tank 210 cannot be greatly influenced.
Similarly, in step S200, an ultraviolet intensity value is also obtained, a value of the second preset height ratio H2 when the ultraviolet intensity value is smaller than the first preset intensity value is smaller than a value when the ultraviolet intensity value is larger than the second preset intensity value, and the first preset intensity value is smaller than the second preset intensity value. When the illumination intensity is relatively high, the water temperature in the water storage tank rises and the final temperature is relatively high, so that the water quantity injected into the heat insulation box 500 by the water storage tank 210 can be larger than that when the illumination intensity is insufficient, even if more hot water is injected into the heat insulation box 500 by the water storage tank 210, the hot water in the water storage tank 210 can be heated as soon as possible by the sufficient illumination intensity, and the requirement that the solar water heater 200 provides hot water for the domestic water of a user is met.
Similarly, in step S200, an ultraviolet intensity value is also obtained, a value of the third preset height ratio H3 when the ultraviolet intensity value is smaller than the first preset intensity value is smaller than a value when the ultraviolet intensity value is larger than the second preset intensity value, and the first preset intensity value is smaller than the second preset intensity value. When the illumination intensity is relatively high, the water temperature in the water storage tank rises and the final temperature is relatively high, so that when the water amount in the heat insulation box 500 is less than 30%, the water storage tank 210 injects hot water into the heat insulation box 500, even if more hot water is injected into the heat insulation box 500 by the water storage tank 210, the hot water in the water storage tank 210 can be heated as soon as possible by enough illumination intensity, and the solar water heater 200 can provide hot water for domestic water of a user.
