In figure: 1-water inlet pipe, 2-magnetic valve, the 3-gate valve of intaking, 4-water heater, 5-outlet pipe, 6-microcomputer controller, 7-water tank, 8-circulating water pipe, 9-water pump, 10-blow-off pipe.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Auto-control energy-saving hot-water heating system as described in Figure 1, comprise water heater 4, the water inlet pipe 1 being connected with the water inlet of this water heater 4 and the outlet pipe 5 being connected with this water outlet of water heater mouth, this water inlet pipe 1 is provided with into water gate valve 3 and check valve, in described water heater 4, be provided with the first temperature sensor, on described water inlet pipe 1, be also provided with magnetic valve 2, described outlet pipe 5 is connected with water tank 7, this water tank 7 is provided with level sensor and the second temperature sensor, this water tank 7 is connected between described magnetic valve 2 and the water inlet of described water heater 4 by circulating water pipe 8 and described water inlet pipe 1, this circulating water pipe 8 is provided with water pump 9 and check valve, also comprise microcomputer controller 6, this microcomputer controller 6 respectively with described the first temperature sensor, described magnetic valve 2, described level sensor, described the second temperature sensor and described water pump 9 are electrically connected.
Described water inlet gate valve 3 is adjustable flow gate valve, can regulate as required flow of inlet water.
Described water heater 4 is made by 304 gapless stainless steel tubes, is 5~7 circle spiral rings, and size adapts with burner hearth.The diameter of this 304 gapless stainless steel tube is 12~26mm, and more preferably, this diameter is 16mm.
The bottom of described water tank 7 is provided with sewage draining exit 10, facilitates the cleaning of water tank 7.The top of this water tank 7 is provided with exhaust outlet 11, for vent tank internal pressure.
Be illustrated in figure 2 the course of work of this auto-control energy-saving hot-water heating system: open system power supply switch, open water inlet gate valve 3; By level sensor, judge in water tank 7 whether water is full, if water less than, opens solenoid valve 2, water inlet pipe 1 is intake, and after water heater 4 heating, through outlet pipe 5, flows into water tank 7; After the interior water of water tank 7 is full, level sensor sends signal to microcomputer controller 6, microcomputer controller 6 is shut electromagnetic valve 2, at this moment the signal transmitting by the first temperature sensor and the second temperature sensor, microcomputer controller 6 judges that whether the interior water temperature of water heater 4 is higher than the interior water temperature of water tank 7, if not being does not open water pump 9, open in this way water pump 9, make the interior water of water tank 7 enter water heater 4 by circulating water pipe 8 circulations and constantly heat to improve water temperature.
Described water heater 4 can be in series by multiple points of water heaters, in each point of water heater, is equipped with temperature sensor.At this moment when judging the interior water temperature of water heater 4 whether higher than water tank 7 interior water temperature, microcomputer controller 6 is by the water temperature in all points of water heaters and the interior water temperature comparison of water tank 7, as long as there is the water temperature of a point of water heater to open water pump 9 higher than the interior water temperature of water tank 7.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
