Abstract

The invention relates to a cooling water removing device for a pipeline of a solar water heater, and belongs to the technical field of energy saving. The device comprises a cooling water reflowing water pump, a solar temperature maintaining box, an exhaust pipe, a hot water discharging valve, a hot water discharging pipe, an used water discharging valve and a returning pipe, wherein the hot water discharging valve is arranged at an outlet in the lower surface of the solar temperature maintaining box and the outlet is connected with the hot water discharging pipe through the hot water discharging valve; the used water discharging valve is connected to the lower surface of the hot water discharging pipe; one end of the cooling water reflowing water pump is connected with the solar temperature maintaining box and while the other end of the cooling water reflowing water pump is connected with the returning pipe; the returning pipe is connected with hot water discharging pipe through the used water discharging valve; the lower end of the exhaust pipe is connected to the hot water discharging pipe and while the upper end of the exhaust pipe is directly communicated with the atmosphere. According to the device, the problem of removing cooling water in the solar pipeline can be solved; the structure is simple; the economy and practicability are ensured; the problem that the solar pipeline is frozen in winter can be solved; the water resource can be saved.

Description

A kind of solar energy water heater pipe cold water removal device
Technical field
The present invention relates to a kind of solar energy water heater pipe cold water removal device, specifically a kind of resident domestic solar water heater pipeline cold water removal device, belongs to field of energy-saving technology.
Background technology
At present, along with the continuous minimizing of global resources, the exploitation of some novel renewable energy becomes more and more important, and solar energy is subject to many-sided attention as a kind of relatively safe, that easy exploiting, potentiality are large pollution-free clean energy resource.Solar water pipeline reaches tens meters, all needs first the cold water in pipeline first to be put totally just can use, will waste a lot of water like this before each use.The present invention adopts a kind of pipeline cold water removal device, empty in pipeline when not using at ordinary times, hot water can directly flow out from warming solar energy case in use, use terminates also can leave hot water in rear solar pipe, if nobody uses drop to the temperature of oneself setting hot water temperature before, in pipeline, residual hot water is then come back in warming solar energy case by another pipeline, thus ensure that water resource is not wasted.Owing to being empty for a long time in the solar pipe when not using hot water, this device solves the freezing problem of solar pipe in winter simultaneously, thus reduces some spendings on defroster.
Summary of the invention
The object of the invention is to provide a kind of solar pipe cold water removal device, which solves the problem that in solar pipe, cold water is removed, this device is arranged on original solar water heater, make solar water heater economize on water, antifreeze, using more convenient, is one i.e. energy-conservation but also device easily.
Technical scheme of the present invention is:
A kind of solar energy water heater pipe cold water removal device, comprise cold-water reflux water pump, warming solar energy case, blast pipe, hot water effluent's valve, hot water outlet pipe, with water outlet valve and return pipe, below warming solar energy case, exit is provided with hot water effluent's valve, and be connected with hot water outlet pipe by hot water effluent's valve, connect below hot water outlet pipe and use water outlet valve, cold-water reflux water pump one end connects warming solar energy case, the other end connects return pipe, return pipe is being connected with hot water outlet pipe with water outlet valve place, blast pipe lower end is connected to hot water outlet pipe, upper end directly communicates with air.
Beneficial effect of the present invention: the invention solves the problem that in solar pipe, cold water is removed, structure is simple, economical and practical, not only solves the freezing problem of solar pipe in winter, can also saving water resource.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing is overall installation figure of the present invention.
In figure: 1. cold-water reflux water pump, 2. warming solar energy case, 3. blast pipe, 4. hot water effluent's valve, 5. hot water outlet pipe, 6. use water outlet valve, 7. return pipe.
Detailed description of the invention
A kind of solar energy water heater pipe cold water removal device, comprise cold-water reflux water pump 1, warming solar energy case 2, blast pipe 3, hot water effluent's valve 4, hot water outlet pipe 5, with water outlet valve 6 and return pipe 7, warming solar energy case 2 is provided with hot water effluent's valve 4 in exit below, and be connected with hot water outlet pipe 5 by hot water effluent's valve 4, hot water outlet pipe 5 connects use water outlet valve 6 below, cold-water reflux water pump 1 one end connects warming solar energy case 2, the other end connects return pipe 7, return pipe 7 is being connected with hot water outlet pipe 5 with water outlet valve 6 place, blast pipe 3 lower end connects hot water outlet pipe 5, upper end directly communicates with air.
When hot water is used, open hot water effluent's valve 4, hot water flows out in warming solar energy case 2, and open with water outlet valve 6, hot water is by flowing out with water outlet valve 6.When stopping using hot water, close use water outlet valve 6 and hot water effluent's valve 4, at this moment remain a pipe hot water in hot water outlet pipe 5 and return pipe 7 cannot normally discharge, when hot water in pipeline is lower than set temperature, cold-water reflux water pump 1 is started working, cold water flow back in warming solar energy case 2 by return pipe 7, and cold-water reflux pump 1 cuts out.When reusing hot water, repeat above operation, another working cycles starts.
