Description
Technical Field

Background
Because of the characteristics of sunlight receiving and reliable bearing, the solar water heater can only be installed on the roof of a roof or a building, and the water consumption position is on the ground or a certain layer of the building, so that the water heater and the water consumption position are separated by tens of meters or even tens of meters. The long pipeline has the advantages that although the long pipeline is provided with heat-insulating cotton, the effect is not ideal, water in a period of time is changed into cold water, so that the water must be drained for more than 1 minute before hot water is used each time, the embarrassing situation that a barrel of cold water is firstly put only when people want to wash hands once with hot water often occurs in winter, time is wasted, and a large amount of water resources are wasted.
When the solar water heater is used in summer with sufficient sunlight, the water can be heated to be boiled due to untimely use. At the moment, even if the solar tube continuously absorbs sunlight for heating, the energy in the water can not be continuously stored, but the heat is radiated into the air in a boiling mode, so that the energy is wasted. If the water feeding operation is performed in the high-temperature state of the solar water heater, the sudden entering of cold water can cause the pipe explosion of the solar water heater, so that the water feeding protection is added to the existing controllers of a plurality of solar water heaters, namely, the water feeding is forbidden when the temperature of the solar water heater exceeds 95 ℃, and the manual water feeding is unsuccessful.
In addition, if frequent intermittent water use is performed, a large amount of hot water is left in the pipeline between the solar water heater and the use of the hot water after each time of water use, and the hot water radiates heat into the air, so that the hot water slowly cools down, and energy waste is caused. In the continuous rainy days, the water temperature of the traditional solar water heater cannot meet the requirements, and if the traditional solar water heater has no electric heating function, the traditional solar water heater cannot be used directly. The energy waste and the water resource waste problem which are mentioned above exist in the case that hot water is needed in a solar container on the roof of a building even though the man-machine adding device with the electric heating function.
In order to solve the above problems, it is necessary to provide an energy-saving and water-saving system of a solar water heater.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In the traditional solar water heater system, a solar water heater is arranged on the roof of a building, and a water level and water temperature sensor in a water tank collects water level and water temperature at any time; when the hot water of the solar water heater is used up (the water level is low), the controller automatically opens the water feeding valve, tap water flows into the water tank of the solar water heater, and when the water is fully discharged (the water level is high), the water feeding electromagnetic valve is automatically closed; when water is used, hot water flows out through the long pipeline and the hot water pipe network. Such a system not only wastes energy during delivery, but also wastes water resources because the water just coming out is cold water.
Therefore, in the present application, a conventional solar water heater system is modified, please refer to fig. 1, and fig. 1 is a schematic structural diagram of the energy-saving and water-saving system of the solar water heater. The solar water heater 7 is arranged on the roof and is used for absorbing solar energy, and then water in the water tank 8 of the solar water heater 7 is heated, so that the water temperature and the water level in the water tank 8 can be monitored in real time, the first water level and water temperature sensor 9 is arranged in the water tank 8, and data information acquired by the first water level and water temperature sensor is transmitted to the controller.
The water tank 8 is respectively connected with the cold water inlet pipe 4 and the water inlet pipe of the heat preservation water tank 11 through the water pipe 6, the water inlet pipe of the heat preservation water tank 11 is provided with a transfer electromagnetic valve 10, and the transfer electromagnetic valve is controlled by a controller and used for transferring hot water in the water tank of the solar water heater into the heat preservation water tank 11.
The cold water inlet pipe 4 is provided with a water feeding electromagnetic valve 5 at one end close to the water pipe 6 for feeding water to the water tank 8 of the solar water heater 7, and is controlled by the controller, and a check valve 1 is provided at one end far away from the water pipe 6 for preventing hot water backflow under the condition that tap water pressure is lower than hot water pressure of the solar water heater when water is fed. The cold water inlet pipe 4 between the check valve 1 and the water feeding valve 5 is respectively connected with each water using device 2 to supply cold water for each water using device 2.
The heat preservation water tank 11 and each water using device 2 are arranged on the same layer, the water outlet pipe 3 of the heat preservation water tank is connected with each water using device 2, and the booster pump 14 is arranged on the water outlet pipe 3 and is used for overcoming the defect of insufficient water pressure caused by too small difference in height between the heat preservation water tank 11 and the water outlet. Referring to fig. 2, fig. 2 is a schematic cross-sectional structure of the heat preservation water tank; in this embodiment, in order to increase the heat insulation performance of the heat insulation water tank 11, the heat insulation water tank 11 includes an outer shell 111 and an inner box 112 disposed in the outer shell 111, a silica aerogel felt wrapping layer 113 is wrapped outside a wall of the inner box 112, and the aerogel felt wrapping layer 113 and the outer shell 111 are disposed at intervals to form an air layer 114; the water inlet pipe and the water outlet pipe 3 are both communicated with the inner box 112, and in order to monitor the water temperature and the water level of the heat preservation water tank 11 in real time and heat and control the temperature of the water in the heat preservation water tank 11, a second water level water temperature sensor 12 and an electric heater 13 are arranged in the inner box 112.
In order to perform comprehensive logic control, the scheme also comprises a controller which is electrically connected with the check valve 1, the water feeding valve 5, the first water level and water temperature sensor 9, the dump solenoid valve 10, the second water level and water temperature sensor 12, the electric heater 13 and the booster pump 14.
Referring to fig. 3, fig. 3 is a control logic flow chart of the energy-saving and water-saving system of the solar water heater.
When the water temperature of the solar water heater reaches the transfer temperature (winter 48, spring and autumn 60 and summer 80), and the heat preservation water tank is used more than 2/5 (namely, the residual water is less than 3/5), the transfer electromagnetic valve is opened to directly put solar water into the heat preservation water tank until the heat preservation water tank is fully filled, the transfer electromagnetic valve is closed to stop water discharge, and the check valve and the water feeding valve are opened to feed water to the solar water heater. Because the hot water is discharged through the heat preservation water tank, the cold water is not required to be discharged for a long time, and water resources are saved.
The heat preservation water tank is used for storing a large amount of hot water, so that the solar water heater is not easy to boil even in summer, solar energy can be always drawn, and the energy absorption rate is improved. Meanwhile, as the temperature of the solar water heater is not easy to exceed the standard, the possibility of pipe explosion caused by feeding cold water to high-temperature solar energy is reduced, and the overall safety of the equipment is improved. When the hot water is frequently used, the hot water is discharged from the heat preservation water tank, so that the frequency of accumulating the hot water in the whole long pipeline from the solar water heater to the using layer is reduced, and the energy loss of the long pipeline hot water is also reduced.
Because the sunlight in winter is weakest, the sunlight in spring and autumn is stronger and the sunlight in summer is strongest, different temperatures in the transfer seasons are set according to the seasonal characteristics. In winter, the sunlight is weak, if the transfer temperature is too high, the water of the solar water heater is not heated to the set transfer temperature all the time, and the data prove that people can wash and not feel cold only by being more than 3 ℃ when bathing, so the transfer temperature is low in winter. And the sunlight is too sufficient in summer, if the transfer temperature is too low, the heat preservation water tank can be easily stored too early, and then the heat preservation water tank is continuously heated and even boiled, so that the transfer function of the heat preservation water tank can not be realized.
Finally, in order to prevent continuous overcast and rainy or solar energy in winter from reaching the temperature of transferring and storing, the water in the heat preservation water tank is used up quickly. When the water level of the heat preservation water tank is less than one fifth, the control program starts the emergency transfer. Although the current temperature of the solar water heater does not reach the storage temperature, the storage solenoid valve is still directly opened to fill the heat preservation water tank with water. And if the detected temperature is less than 42 ℃, the electric heater is started to heat the water in the incubator to 42 ℃.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
