Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is control circuit schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
In Full-automatic hot-water device shown in Fig. 1, the attemperater that still disposes solar water heater and be communicated with solar water heater output pipe 2; These and prior art are roughly the same.
Improvement of the present utility model, is by a return pipe 3, described attemperater and solar water heater to be connected, and also configures the second temperature sensor of a perception water temperature in attemperater; In the water inlet pipe 1 of solar water heater, dispose entering water electromagnetic valve F1 again, described return pipe disposes backwater water pump B, also configures the first temperature sensor of a water temperature detection in solar water heater; Described attemperater also disposes the first liquid-level switch (setting high level value) and the second liquid-level switch (setting low level value).
The outlet pipe of attemperater is connected at least one hot water outlet, offers user and uses; Described water pump, magnetic valve, temperature sensor and liquid-level switch are all communicated with a control circuit by wire.
The top of described attemperater also arranges an overfall; Therefore, this attemperater is in atmospheric pressure state.
Obviously, return pipe, output pipe and attemperater all should configure good heat-insulation layer; This is general knowledge, without stating more.In addition, the equal buyable of described gauge tap, water pump, magnetic valve, temperature sensor and liquid-level switch obtains.
In the electric control circuit schematic diagram that Fig. 2 shows, entering water electromagnetic valve and the series connection of the 3rd relay normally open contact form a branch road, backwater water pump and the series connection of the second relay normally open contact form another branch road, and two branch circuit parallel connections access between 220V live wire and ground wire.The primary coil access 220V power supply of transformer Z1, secondary coil (conventionally can be set as 12V) is connected in series the first relay J 1 normally-closed contact, the first liquid-level switch, the second liquid-level switch and the rear formation of the 3rd relay J 3 loop successively; Wherein the two ends of the second liquid-level switch are also connected by the 3rd branch road; Two minutes branch circuit parallel connections of the 3rd route form, and within one of them minute, are connected in series the normally opened contact of the second relay normally-closed contact and the 3rd relay in branch road, the normally opened contact of serial connection and the interlock of the second relay normally-closed contact in another minute branch road.
In addition, the first relay J 1 with after the second relay J 2 parallel connections, connect with control chip IC (chip model is preferably 16F883) again, then access the secondary coil of transformer Z1, the first temperature sensor, the second temperature sensor are distinguished the signal input part of Access Control chip IC.
All outsourcing acquisitions of all electronics, electric components above.
Operation principle of the present utility model is as follows:
One, the temperature recording when the first temperature sensor is higher than 40 ℃ (can determine as required) and the temperature that records than the second temperature sensor during higher than 10 ℃ (adjustable), control circuit starts the second relay J 2 makes water pump B work carry out hot and cold water exchange, starts the 3rd relay J 3 simultaneously and opens the supplementary attemperater water level of entering water electromagnetic valve F1.
Two, the temperature recording when the first temperature sensor is higher than 40 ℃, but the temperature altitude recording than the second temperature sensor is poor in 0-10 ℃ time (adjustable), do not start the 3rd relay J 3 as water level during higher than the second liquid-level switch; Otherwise, as water level, starting the 3rd relay J 3 during lower than the second liquid-level switch, control circuit is opened entering water electromagnetic valve and is supplemented attemperater water level.
Three, water level completely makes the first liquid-level switch 1 disconnect, or the temperature that records of the first temperature sensor disconnects the first relay J 1 during lower than 40 ℃, meets wherein any one condition, and control circuit all can make the 3rd relay disconnect entering water electromagnetic valve is quit work.
