Description
The utility model relates to a kind of auxiliary heating of solar water heater device.
Present most of solar water heater all belongs to the photo-thermal conversion hysteria, it is very convenient and effective when sunny, but when increasing hot water supply and accidental change water custom when the illumination deficiency or because of certain reason, it just can not supply temperature required and hot water quantity immediately temporarily.General way is the electric auxiliary heating device that installs time control and temperature control additional at present, predefined with hot water in the period, if the water temperature in the solar water heater water tank does not reach under the water temperature of predefined requirement in limited time, just connect the electric heater unit that is installed in the water tank automatically, just stop heating on the predefined water temperature in limited time up to the heating of the water in the water tank has been reached, this assisted heating device has following shortcoming:
1 set with hot water beyond the period, even water temperature reach requirement can not be with the assisted heating device supplementary heating for use.
2 no matter the same day or needed at that time with the hot water amount what, when needs are used the assisted heating device supplementary heating, all water whole in the water tank must be heated to predefined temperature upper limit, it is chronic that this not only needs to heat, consumes energy is big, can not obtain temperature required hot water immediately, also often cause waste.
3 since the temperature sensor of control assisted heating device work and electrical heating elements all in the water tank of solar water heater, like this, the cooling water that accumulate earlier in delivery pipeline Central Plains just can not add heat utilization again, can only emptying cause waste.
The thermal efficiency of 4 displacement type water heaters is relevant with water consumption, and generally speaking, its energy conversion efficiency is low, the operating cost height.
The purpose of this utility model is to provide a kind of auxiliary heating of solar water heater device, and it can be at any time, and the hot water of temperature required abundance is provided quickly and efficiently.
The technical solution of the utility model is:
A kind of solar water heater combustion gas assisted heating device, it is characterized in that comprising temperature sensor, main solenoid valve, pilot solenoid valve, full-automatic water-flowing gas water heater, control circuit, main solenoid valve wherein, the water inlet end of pilot solenoid valve and connect the back be connected with the output end of hot water E of solar water heater, on tie point E, be provided with temperature sensor, the main solenoid valve water side then is connected in series the water inlet of full-automatic water-flowing gas water heater, and the latter's delivery port links to each other with the water side of pilot solenoid valve and be communicated with the hot water user, the detection signal input control circuit of temperature sensor, and main solenoid valve, pilot solenoid valve is controlled by control circuit.
The utility model is simple in structure, and is easy to use, can not use the assisted heating device supplementary heating when water temperature reaches requirement, saves the energy.
Below in conjunction with accompanying drawing structure of the present utility model is done detailed explanation
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a control circuit block diagram of the present utility model
Fig. 3 is the circuit diagram of control circuit of the present utility model
The utility model comprises temperature sensor 1, main solenoid valve 2, pilot solenoid valve 3, full-automatic water-flowing gas water heater 4, control circuit 5, wherein main solenoid valve 2, the water inlet end of pilot solenoid valve 3 and connect the back be connected with the output end of hot water E of solar water heater 13, on tie point E, be provided with temperature sensor 1, main solenoid valve 2 water sides then are connected in series the water inlet of full-automatic water-flowing gas water heater 4, and the latter's delivery port links to each other with the water side of pilot solenoid valve 3 and be communicated with the detection signal input control circuit 5 of temperature sensor 1 with the hot water user, and main solenoid valve 2, pilot solenoid valve 3 is by control circuit 5 controls.
Main solenoid valve 2 and pilot solenoid valve 3 manual bypass water valves 6,7 respectively constitutes, and the bypass water valve is set is to use when having a power failure.
Control circuit 5 is mainly by temperature sensing circuit 8, constant-current source circuit 9, and linear amplifier circuit 10, comparison circuit 11, on-off circuit 12 constitutes, temperature sensing circuit 8, constant-current source circuit 9, linear amplifier circuit 10, comparison circuit 11, on-off circuit 12 are connected in series successively.
Constant-current source circuit 9 is by amplifier A
1, triode BG1, Zener diode D1, resistance R
1-R
5Form, when water temperature causes R
8Resistance and terminal voltage when changing, it makes the electric current of the temperature sensing circuit 8 of flowing through constant.Thereby guaranteed certainty of measurement.
On-off circuit 12 is by reverser G1, G2, and triode BG2, BG4, Darlington transistor BG3, BG5, diode D3-D6, resistance R 17-R26 forms, and on-off circuit is mainly in order to the keying of control magnetic valve group.
The utility model operation principle is:
After temperature sensor measurement pipeline water temperature at that time, be input to control circuit 8, compare, according to comparative result output control signal with predefined water temperature, a magnetic valve is opened and another closed electromagnetic valve, and the water of solar water heater 13 outputs can only be from wherein pipeline outflow.When the water temperature that records is lower than predefined water temperature, the main solenoid valve group is opened, during hot water user water, water flows through from full-automatic gas-fired water heater, gas heater is lighted automatically and is carried out supplementary heating, when reverse situation, then to close main solenoid valve and open pilot solenoid valve, water directly flows to the user and without full-automatic gas-fired water heater.
The operation principle of control circuit 5 is:
When water temperature is low, the resistance of R8 is higher, when the linear amplifier circuit output voltage is lower than the voltage of representing design temperature, and comparison circuit 13 output high level, thereby make reverser G1 output low level, and making triode BG2, Darlington transistor BG3 conducting is opened control signal to main solenoid valve output, reverser G2 output this moment high level, and making triode BG4, Darlington transistor BG5 ends, to pilot solenoid valve output shutdown signal.Therefore, the water of solar water heater output flows to gas heater through main solenoid valve, and when the user used water heater, the water outlet pipe of flowing through after the gas heater supplementary heating used for the user.
