Abstract
The utility model relates to an instantaneous heating control system of a solar water heater, which is characterized in that a circulation water loop consisting of a water outlet pipe section, a water inlet pipe section and a circulation pipe section is arranged between the water outlet and the overflow of a water storage tank. A circulating pump and a temperature controller are connected in series in the circulation water loop, and the circulation pipe section is positioned at the place of indoor water supply. A water inlet branch, a water consumption branch and a water return branch are arranged on the circulation pipe section in the three-way way. The heating control system provided by the utility model can realize the instantaneous heating, thereby not only avoiding directly discharging cool water, but also realizing convenient use to a large extent.
Description
Technical field:
The utility model relates to control system of solar energy water heater, more specifically says so in solar water heater, is used for avoiding the control system of open stage discharging cold water.
Background technology:
The domestic solar water heater who generally uses is owing to be arranged on indoor with tap at present, and that storage tank is placed on is outdoor, comprise that storage tank is arranged on the roofing or in the courtyard, the unified problem that exists is at storage tank and indoor a segment distance is arranged between with tap, because the outlet pipe of storage tank can't emptying, therefore, the each unlatching when using tap, at first discharging is chilled water in the outlet pipe, certainly, also can this section cold water be collected reuse from water-saving angle, but because of operational inconvenience, most of people can not adhere to accomplishing this point, and more often, this section cold water is directly discharged.According to not waiting of distance, the cold water of each discharging will reach the 5-15 liter usually, on average at every turn by 10 liters, each household water every day 3 times, then then wasting clean water every day is 30L, and annual just have 10.95 tons water therefore to run off, and the scarcity of water resource makes this phenomenon of wasting water be eager to be resolved.But also there is not a kind of effective technical scheme to be used for addressing this problem so far.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, being used for avoiding open stage discharging cold water to reach the solar water heater instant-heating control system of the purpose of conserve water resource thereby provide a kind of.
The technical scheme that the utility model technical solution problem is adopted is:
Design feature of the present utility model is between the delivery port and gap of storage tank, the circulation waterway that setting is made of water outlet pipeline section, entry pipeline section and circulation pipeline section, series connection is provided with circulating pump and temperature controller in described circulation waterway, the circulation pipeline section is arranged on indoor water level and puts, on described circulation pipeline section, the form with threeway connects water inlet branch road, water branch road and backwater branch road respectively.
Design feature of the present utility model also is in the water inlet branch road water intaking valve to be set, to be provided with tap, in the backwater branch road back-water valve (BWV) to be set at the water branch road.
Temperature controller adopts the electric contact type temperature controller.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is by being provided with circulating pump, make the water in the circulation waterway be able to circulate with storage tank, make sometimes, start circulating pump and the cold water in the circulation waterway can be injected storage tank, the water of discharging in tap by the water branch road is the hot water in the storage tank, reaches the purpose of instant-heating.Not only effectively avoided the direct discharging of cold water, the form of its instant-heating also is very easy to use.
2, the utility model is provided with temperature controller, circulation according to the actual temperature control pump in the circulation waterway, when temperature is lower than 35 ℃, circulating pump is devoted oneself to work, and stop circulation when temperature reaches 35 ℃ in circulation waterway at once, circulating pump is operated under the most effective situation, both can reduce the power consumption of circulating pump, also can prolong the service time of pump.
3, simple in structure, the structure that do not change existing storage tank itself of the utility model can be mated with any type of solar water heater, and is easy to implement.
Description of drawings:
Fig. 1 is the utility model structural representation.
Number in the figure: 1 storage tank, 2 delivery ports, 3 gaps, 4 water outlet pipeline sections, 5 entry pipeline sections, 6 circulation pipeline sections, 7 circulating pumps, 8 temperature controllers, 9 water inlet branch roads, 10 water branch roads, 11 backwater branch roads, 12 water intaking valves, 13 usefulness taps, 14 back-water valve (BWV)s.
Below by the specific embodiment, the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment:
Referring to Fig. 1, present embodiment is between the delivery port 2 and gap 3 of storage tank 1, the circulation waterway that setting is made of water outlet pipeline section 4, entry pipeline section 5 and circulation pipeline section 6, series connection is provided with circulating pump 7 and temperature controller 8 in circulation waterway, circulation pipeline section 6 is arranged on indoor water level and puts, on circulation pipeline section 6, the form with threeway connects water inlet branch road 9, water branch road 10 and backwater branch road 11 respectively.
In concrete the enforcement, need be in water inlet branch road 9 relative set water intaking valve 12, water branch road 10 relative set with tap 13, in backwater branch road 11 relative set back-water valve (BWV) 14.
Temperature controller 8 can adopt the electric contact type temperature controller, and the control signal of circulating pump 7 working power through and off is provided by temperature controller 8.
In concrete the enforcement, multiple mode of operation can be set, comprise:
Automatically control: before hot water, at first open the control system power switch, when temperature controller detects water temperature in the circulation waterway and is lower than 35 ℃, connect the circulating pump working power, circulating pump is devoted oneself to work, about subsequently 5-10 second, the cold water in the circulation waterway is injected into storage tank, simultaneously, hot water in the storage tank is injected circulation waterway, circulating pump quits work thereupon, with can directly discharging hot water in the tap, embodies the version of instant-heating.
Manually control: when the water temperature in the storage tank is lower than 35 ℃ of the control temperature of temperature controller, directly utilize hand switch manually to control the duty of circulating pump as required, can avoid the direct discharging of cold water equally.
When the rainy weather water tank does not have hot water continuously, turn-off the complete machine power supply.
