Description

The solar water heater device of saving water and energy
Affiliated technical field
The utility model relates to solar water heater field, especially a kind of solar water heater device of saving water and energy.
Background technology
Solar water heater is used widely because of its green, the advantage such as energy-conservation, easy to use.Solar water heater mainly contains and relies on two types of sunshine heating and electric auxiliary heatings completely.At present, the shortcoming of solar water heater mainly: the solar water heater that is placed in roof or roof to delivery port in user room has longer pipeline, especially serious for higher floor.After each use, in this part pipeline, can store a certain amount of water, and its temperature also can reduce gradually.While reusing water heater, because the water temperature in this segment pipe is lower, can not be directly used in bathing.User can bleed off these water conventionally, until leaving water temperature adapts to bathing.So both caused the waste of water resource, and brought inconvenience to again user's use.On the other hand, overcast and rainy or autumn and winter season, it is temperature required that the leaving water temperature of solar water heater cannot reach.Although, adopt traditional electrothermal tube auxiliary heating in the water tank of solar water heater can meet instructions for use, but there is the defects such as the efficiency of heating surface is low, cost is high, difficult in maintenance in it, meanwhile, still water-heater water tank to the cold water of storing in water pipe between user room delivery port first to be bled off and could normally use.The defect that above-mentioned these solar water heaters exist is waste water resource both, brings inconvenience again to user, has also limited its popularization at cold district.
Summary of the invention
Based on this, the utility model proposes a kind of solar water heater device of saving water and energy, comprise pipeline II3, temperature sensor 4, threeway electromagnetic water valve 5, pipeline III6, duct type frequency-changing electric heater 7, pipeline IV8, three-way connection 9, pipeline V10, pipeline VI11, fluid pressure sensor 12, pipeline VII13, thermoregulator 18, power switch 19 and controller 20.
Automatic regulating device for solar water heater described in the utility model, is characterized in that: one end of the pipeline II3 of metal material is connected with the water tank 1 of solar water heater by pipeline I2, and the other end is connected with the water inlet of threeway electromagnetic water valve 5.Temperature sensor 4 is fixed on the outer wall of pipeline II3.A delivery port of threeway electromagnetic water valve 5 is connected with the water inlet of duct type frequency-changing electric heater 7 by pipeline III6, and another delivery port is connected with a water inlet of three-way connection 9 by pipeline V10.The delivery port of duct type frequency-changing electric heater 7 is connected with another water inlet of three-way connection 9 by pipeline IV8.The delivery port of three-way connection 9 is connected with the water inlet of fluid pressure sensor 12 by pipeline VI11.The delivery port of fluid pressure sensor 12 is connected with the hot water inlet of tap 14 by pipeline VII13.The cooling water inlet of tap 14 is connected with municipal tap water pipe network by pipeline VIII15.The delivery port of tap 14 is connected with shower nozzle 17 by pipeline IX16.Thermoregulator 18 (not shown in figure 1)s and controller 20 (not shown in figure 1)s are installed on the correct position on device.Temperature sensor 4, fluid pressure sensor 12, thermoregulator 18 and power switch 19 all have electrical connection with controller 20.Duct type frequency-changing electric heater 7 in the utility model adopts converter technique to control.
The utility model utilization detects and control technology automatically, in saving water resource, improved the convenience that solar water heater is used, adopt frequency conversion control technique to guarantee that with lower power consumption solar water heater can be used in throughout the year in the lower weather of southern temperature and north cold area, has a extensive future.
Accompanying drawing explanation
Fig. 1 be the utility model structure and with the connection diagram of solar water heater water tank and tap.
Fig. 2 is the control flow chart of whole device.
In figure, water tank 1, pipeline I2, pipeline II3, temperature sensor 4, threeway electromagnetic water valve 5, pipeline III6, duct type frequency-changing electric heater 7, pipeline IV8, three-way connection 9, pipeline V10, pipeline VI11, fluid pressure sensor 12, pipeline VII13, tap 14, pipeline VIII15, pipeline IX16, shower nozzle 17, thermoregulator 18, power switch 19, controller 20.
The specific embodiment
As depicted in figs. 1 and 2, while using water heater, first power-on switch 19, then open water tap 14.After tap 14 is opened, the hydraulic pressure in pipeline VII13 diminishes, and fluid pressure sensor 12 outputs signal to controller 20.Controller 20 enters duty, starts the temperature T 0 of water in pipeline II3 that collecting temperature sensor 4 records, and itself and the temperature T 1 of thermoregulator 18 settings are compared.When T0 is less than T1, controller 20 is given threeway electromagnetic water valve 5 and duct type frequency-changing electric heater 7 output control signals simultaneously, control current and enter pipeline III6, make 7 energisings of duct type frequency-changing electric heater simultaneously, and according to temperature T 0 and the difference of T1, duct type frequency-changing electric heater 7 is carried out to VFC, water is quickly heated up to design temperature.Heated water is successively by pipeline IV8, three-way connection 9, pipeline VI11, fluid pressure sensor 12, pipeline VII13, enters shower nozzle 17 for user with enter the cold water of tap 14 by pipeline IX16 together with through piping IX16.After duct type frequency-changing electric heater 7 to residual cold water in pipeline between the water tank 1 of solar water heater is heated and uses, the hot water in water tank 1 enters pipeline I2 and pipeline II3.If controller 20 detects T0 and is more than or equal to T1, controller 20 outputs signal to threeway electromagnetic water valve 5, controls current and enters pipeline V10, makes 7 power-off of duct type frequency-changing electric heater simultaneously.Hot water is successively by three-way connection 9, pipeline VI11, fluid pressure sensor 12, pipeline VII13, enters shower nozzle 17 with enter the cold water of tap 14 by pipeline IX16 together with through piping IX16.When user uses water heater, controller 20 detects the temperature T 0 of water in pipeline II3 in real time, and automatically control by setup program threeway electromagnetic water valve 5 and duct type frequency-changing electric heater 7 according to the magnitude relationship of T0 and design temperature T1, and control by the handle of tap 14 ratio that hot and cold water mixes, guarantee that the leaving water temperature of shower nozzle 17 meets the requirements.During closed tap 14, it is large that the hydraulic pressure in pipeline VII13 becomes, and controller 20 detects after the output signal of fluid pressure sensor 12, closes threeway electromagnetic water valve 5, makes 7 power-off of duct type electrothermal device, and makes whole device enter low-power consumption standby state.
