The device comprises an N-shaped upper and lower water pipe, one end of which is connected with a water tank and extends to the bottom of the water tank; The other end of the "N"-shaped upper and lower water pipes is connected with the control valve, which is respectively controlled by the shower control valve and the upper and lower water valves; The water level in the N-shaped upper and lower water pipes is controlled by different on-off valves of the emptying valve connected with the emptying pipe; Water supply, bathing and emptying are realized by siphon principle. The utility model has the advantages of simple structure, low cost, simplicity, quick and thorough emptying speed and broad market prospect.
Maintenance:
1, the system regularly discharges pollutants to prevent pipeline blockage; And clean the water tank to ensure the water quality is clean. When discharging sewage, as long as the water inflow is normal, just open the drain valve until clean water flows out of the drain valve.
2. Regularly remove the dust and dirt on the transparent cover plate of the solar collector, keep the cover plate clean and ensure high light transmittance. Cleaning should be carried out in the early morning or evening when the sun is not strong and the temperature is low, so as to avoid the transparent cover plate being crushed by cold water.
3. Pay attention to check whether the transparent cover plate is damaged, and replace it in time if it is damaged.
4. For vacuum tube solar water heater, always check the vacuum degree of vacuum tube or whether the inner glass tube is broken. When the barium-titanium getter of vacuum tube turns black, it shows that the vacuum degree has decreased and the collector tube needs to be replaced.
5. Vacuum tube solar water heater not only cleans the vacuum tube, but also cleans the reflector at the same time.
6. Inspect the pipelines, valves, ball valves, solenoid valves and connecting hoses for leaks, and repair them in time if any.
7. If the heat absorption coating of the heat collector is damaged or falls off, it should be repaired in time. All supports and pipes should be painted with protective paint once a year to prevent corrosion.
8, to prevent stuffy sun. Stopping the circulation of the circulation system is called stuffy sun, which will lead to the increase of the internal temperature of the collector, damage the coating, deform the insulation layer of the box and break the glass. The reason of stuffy sun exposure may be the blockage of circulating pipeline; In the natural circulation system, it may also be caused by insufficient cold water supply and the water level in the hot water tank is lower than that in the upper circulation pipe; In the forced circulation system, it may be caused by the stop of the circulating pump.
9. All-weather hot water system with auxiliary heat source should be installed, and the auxiliary heat source device and heat exchanger should be checked regularly for normal operation. The auxiliary heat source is heated by electric heating tube, and the leakage protection device must be reliable before use, otherwise it cannot be used. For the heat pump-solar energy heating system, it is also necessary to check whether the compressor and fan of the heat pump are working normally, and eliminate the faults of any components in time.
10, when the temperature is lower than 0℃ in winter, the water in the collector should be discharged in the plane system; If a forced circulation system with the function of antifreeze control system is installed, it is only necessary to start the antifreeze system without emptying the water in the system.
Skills:
In the process of using solar water heater, if the water supply time and quantity are arranged and used skillfully, it will achieve twice the result with half the effort. Users who just started using it may not be very clear. After a long time, they will gradually explore the experience and laws.
1. When taking a shower, if the water in the solar water heater has been used up, but people haven't washed it clean, then you can take cold water for a few minutes, and use the principle that cold water sinks and hot water floats to push the hot water out of the vacuum tube, and then you can take a shower.
2. Using the principle of 1, if there is still a little hot water in the solar water heater after bathing, you can wash a person with cold water for a few more minutes.
According to the weather forecast, we can get a satisfactory water temperature. If it is sunny tomorrow, you can irrigate it; If it is cloudy or cloudy, the upper part of the water tank is filled with water; If it rains, keep the raw water without cold water.
4. After taking a shower at night, if there is still half of hot water of nearly 70 degrees in the water tank of the water heater, in order to prevent excessive heat loss (the less water, the faster heat loss), the water quantity should be determined according to the water temperature predicted by the weather. Tomorrow will be sunny and full of water; On rainy days, two-thirds of the water is filled.
5. Cold and hot water adjustment: water heater water temperature adjustment steps: first open the cold water valve, properly adjust the cold water flow, and then open the hot water valve to adjust until the required bath temperature is reached. In addition, the amount of cold water can be determined by experience according to the weather conditions, and the nozzle should not be pointed at the human body to avoid burns.
6. Wind-resistant measures: the components of the solar water heater are connected reliably, and the wind-resistant performance mainly depends on its installation and fixing method.
7. How to prolong the service life of solar water heater: In order to prolong the service life of solar water heater, users should pay attention to: after the water heater is installed and fixed, non-professionals should not move or disassemble it easily to avoid damaging key components; There should be no sundries around the water heater to eliminate the hidden danger of hitting the vacuum tube; Regularly check the vent to ensure smooth flow, so as to avoid bursting or deflation of the water tank; When cleaning the vacuum tube regularly, be careful not to damage the tip of the lower end of the vacuum tube; Solar water heaters with auxiliary electric heating devices should pay special attention to water supply to prevent dry burning without water.
8. Skills of using solar water heaters in winter:
When the temperature is not too low (5-7℃), if there is still hot water in the water tank after using water that night, it is advisable to fill the solar water heater with water immediately to reduce the water temperature in the water tank and the heat loss that night and make full use of the heat energy; If the temperature is low, it is best to supply water tomorrow morning, which will help prevent the pipeline at the outlet of the water heater from freezing.
Listen to the weather forecast. If the sunshine is not strong that day, you can fill half a box of water, or you can fill half a box of water according to actual needs. If the water consumption is large, you can consider turning on the electric heating in the solar water heater, or putting the water in the solar water heater into the electric water heater to heat it slightly.
