The solar water heater of band gas heater
Technical field
The present invention relates to a kind of solar utilization technique, particularly a kind of solar water heater with gas heater.
Background technology
The function of solar water heater realizes it being to rely on weather basically, so the stability of its hot water supply often can't guarantee.Therefore how to make the continuous comfortable use of solar water heater, become the problem that needs solve.At present the most general way is that electrical auxiliary heater is installed in solar water heater water tank, but because of general solar water heater be installed in outdoor and volume relatively large, cause power consumption higher.And common solar water heater in use, generally all has certain cold water in the outdoor pipe, and can't realize promptly opening promptly has hot water.
And the gas heater technical elements is comparatively ripe, and hot water can stably be provided, but in resource anxiety and environmental problem more and more outstanding today, allows product more energy saving economy and environmental protection, becomes an important topic.
Summary of the invention
Technical problem to be solved by this invention is the deficiency at existing non-pressure-bearing solar water heater and gas heater technology, and the solar water heater of the band gas heater of a kind of instant-heating, reliable and stable, economical and energy saving is provided.
Technical problem to be solved by this invention is to realize by following technical scheme: a kind of solar water heater with gas heater, comprise solar water heater and cold water inlet, it is characterized in that also comprising the gas heater magnetic valve, triple valve, controller, temp probe and mixed water valve, wherein solar water heater is communicated with cold water inlet by triple valve, the outlet pipe of solar water heater is communicated with the water inlet pipe that connects gas heater by triple valve, magnetic valve is located on the cold water inlet, controller is located in the gas heater, temp probe is located on the delivery port of water inlet pipe of gas heater, controller respectively with temperature
Probe and magnetic valve are electrically connected, and the outlet pipe of gas heater is communicated with a water inlet of mixed water valve, and another water intake end that mixes water valve is communicated with cold water inlet pipe.
Be provided with a sensor at described solar water heater, sensor is electrically connected with controller.
Between described cold water inlet and triple valve, be provided with a check-valves.
The water inlet pipe of described gas heater is provided with automatic increase pump.
Be provided with reversal valve between described automatic increase pump and the gas heater.
The present invention's beneficial effect compared with prior art: the solar water heater is promptly opened just have hot water, can realize round-the-clock stable hot-water supply, at maximum using solar energy simultaneously, the significantly minimizing of gas consumption has realized combination comfortable, the economic and energy saving environmental protection.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is another embodiment of Fig. 1.
The specific embodiment
The present invention is described in more detail below in conjunction with the drawings and Examples explanation.
Embodiment one
As shown in Figure 1, a kind of solar water heater with gas heater, comprise solar water heater 1 and cold water inlet 11, characteristics of the present invention are also to comprise gas heater 2, magnetic valve 8, triple valve 13, controller 12, temp probe 5 and mixed water valve 4, wherein solar water heater 1 is communicated with cold water inlet 11 by triple valve 11, the outlet pipe 9 of solar water heater 1 is communicated with the water inlet pipe 15 that connects gas heater 2 by triple valve 11, magnetic valve 8 is located on the cold water inlet 11, controller 12 is located in the gas heater 2, temp probe 5 is located on the delivery port of water inlet pipe 15 of gas heater 2, controller 12 is electrically connected with temp probe 5 and magnetic valve 8 respectively, the outlet pipe 16 of gas heater 2 is communicated with a water inlet of mixed water valve 4, and another water intake end that mixes water valve 4 is communicated with cold water inlet pipe 11.
On described solar water heater 1, be provided with a sensor 10, on the water inlet pipe 9 of solar water heater 1, be provided with second ball valve 2.
Between described cold water inlet 11 and triple valve 13, be provided with a check-valves 7, between check-valves 7 and triple valve 13, be provided with first ball valve 12 on the cold water inlet 11.
During work, cold water flows to water inlet pipe and water outlet pipe 9 from cold water inlet 11 water inlets by magnetic valve 8 and check-valves 7, on solar water heater 1, and 1 pair of cold water heating of solar water heater; At this moment, magnetic valve 8 cuts out, heated hot water flows into the water inlet pipe 15 of gas heater 2 from water inlet pipe and water outlet pipe 9, temp probe 5 on the gas heater 2 measures the not enough temperature of hot water, gas heater 2 heating, perhaps the temp probe 5 of gas heater 2 measures the enough temperature of hot water, gas heater 2 water outlet hot water, hot water mixes to mixing water valve 4, ejects from gondola water faucet.
It mainly is that main energy sources once heats with solar energy, and gas heater 2 carries out the secondary supplement heating.Making full use of under the prerequisite of solar energy, guaranteeing instantaneity, the comfortableness of hot water supply.Supporting various informative of this unit mahine can carry out series, parallel and connection in series-parallel etc. with gas heater.And can carry out multi-form configuration according to product function and user demand.The core of this technology has been to realize the integrated and economy utilization of compound energy system height.
Embodiment two
As shown in Figure 2, other the same with embodiment one, different is to be provided with automatic increase pump 6 on the water inlet pipe 15 of described gas heater 2, increases reversal valve 3 increasing automatically to be provided with between pump 6 and the gas heater 2, to realize the pipeline automatic switchover.
The water inlet pipe 15 of gas heater 2 of the present invention and outlet pipe 16 are high temperature resistant designs, can stand the injection of continuous 95 ℃ of high-temperature water, still can guarantee the operate as normal of gas heater 2.
