Abstract

The utility model relates to a solar water heater, in particular to a water-saving solar water heater, which belongs to the technical field of the solar water heater. For the solar water heater, a cold water backflow tube of which the lower end is connected with a hot water tube and the upper end leads to a hot water tank is arranged at home. The cold water backflow tube is provided with a water pump. The cold water tank is arranged on an upper opening of the hot water tank. The bottom of the cold water tank is a plane which is tilted down. The water-saving solar water heater has the advantages of simple structure, saving water for high-rise building, and less heat loss.

Description

A kind of water saving apparatus for heating water by solar energy
Technical field:
The utility model is a kind of solar water heater, and particularly a kind of apparatus for heating water by solar energy with water-saving function belongs to technical field of solar water heaters.
Background technology:
Solar water heater is domestic unique commercial heliotechnics application product, and is of many uses, with the hot water of solar energy heating, saved ample resources, reduced pollution.But the reason that prior solar water heater is constructed owing to equipment in the link of water heating and hot water supply has caused certain water resource waste.For example high more at floor, the cold water that is trapped in the hot-water line is just many more, need discharge the cold water of a large amount of delays in the time of using hot water, has caused very big water resource waste, or has brought a lot of operational troubles to the user; When fine, the water in the boiler can produce boiling at sunshine, with the steam form heat energy that runs off in a large number.
Summary of the invention:
The purpose of this utility model is to overcome the prior art deficiency, and a kind of energy-conserving and environment-protective are provided, low cost, simply constructed automatic regulating device for solar water heater.
Realize that the technical scheme that the utility model above-mentioned purpose is taked is: the cold-water reflux pipe that a lower end is connected with hot-water line, hot water is led in the upper end is set in that the user is indoor, and on the cold-water reflux pipe, water pump is housed, cold water storage cistern places the upper open end of hot water, and is bottom incline at the bottom of the cold water storage cistern.
The lower end of the cold-water reflux pipe of this water saving device is provided with valve, and the upper end delivery port is higher than the last station of the floating ball valve of rehydration of hot water, and delivery port place in upper end is provided with a ball-cock assembly.
Upper open end in hot water is equipped with screen pack, and water pump that is provided with on the indoor cold-water reflux pipe of user and valve are what link.
The beneficial effects of the utility model are: the cold water that remains in the hot-water line is circulated under the water pump effect in boiler and the cold-water reflux pipe, and flow into hot water in the hot-water line, and can cool off effectively and reclaim the steam that produces in the solar water heater heating process, make full use of water resource.And have efficient low-consume, simple structure etc. a bit.
Description of drawings:
Fig. 1 is the utility model structural representation.
Among the figure: cold water storage cistern 1, screen pack 2, ball-cock assembly 3, ball-cock assembly 4, cold water pipe 5, cold-water reflux pipe 6, heat-insulation layer 7, hot water 8, valve 9, shower head 10, hot-water line 11, hot-water valve 12, Cold water tap 13, water pump 14.
The specific embodiment:
Referring to Fig. 1, the indoor hot-water line 11 of the lower end of cold-water reflux pipe 6 and user is connected, the hot water 8 on roof is then led in the upper end, and water pump 14 is arranged on the indoor cold-water reflux pipe 6 of user, and on cold-water reflux pipe 6, also be equipped with one with water pump 14 interlock valve 9.Open the upper end of hot water 8, and screen pack 2 is installed, and cold water storage cistern 1 is installed again above screen pack 2, and the bottom surface of cold water storage cistern 1 is a bottom incline, has constituted 1 top of hot water 8.The upper end delivery port of cold-water reflux pipe 6 is arranged on the last station position of the floating ball valve of rehydration 4 that is higher than hot water 8, and while delivery port place in upper end also is provided with another ball-cock assembly 3.
When needing to use hot water, at first start water pump 14, Lian Dong valve 9 is also opened simultaneously each other, and the delay cold water in the hot-water line 11 is pumped in the hot water 8 on roof.When injecting hot water in the hot-water line 11, switch off the pump 14 and valve 9 simultaneously, open valve 12, shower head 10 can go out hot water, adjusts valve 13, water temperature can be adjusted to suitable temperature.When sunshine on daytime is sufficient, produce steam in the hot water 8, the steam that rises runs into the bottom surface of cold water storage cistern 1 and aggegation, heated the water in the cold water storage cistern 1 on the one hand, the water of a large amount of aggegations flows back to hot water 8 along bottom incline on the other hand, both reclaimed steam heat energy, and reduced a large amount of steams again and escaped the waste that causes.Leave vapor outlet port between cold water storage cistern 1 and the hot water 8, have dust sometimes and enter, but the screen pack 2 of hot water 8 upper ends can stop, thereby keep in the hot water 8 water quality clean.
