Description

A kind of anti-freezing solar water heater

Technical field

The utility model is related to a kind of anti-freezing solar water heater.

Background technology

At present, solar water heater can continuously provide cheap hot water to resident, and environment is not polluted. Its advantage significantly, so not footpath and walk, rapid popularization. Rows of solar water heater is assembled with present many residential buildings, it makes the resident in building bask and facilitate when with water, it is into the treasured in a family of resident. Though solar water heater is the treasured in family, but also one big shortcoming, it is exactly that, in terribly cold night in winter, can be frozen in upper and lower conduit, pipeline is by after ice-bound closing, water cannot circulate wherein, and daytime, sunlight was also warmer sometimes, the water temperature in water tank can be made to rise to 20 DEG C or so, but due to upper and lower conduit by it is ice-bound live, warm water in water tank cannot just be utilized, and this is very unfortunate. When the same day is colder, upper and lower conduit can even be caused the accident by bursting by freezing, and this just brings very big trouble and worries to user. The north of residential building is typically all arranged at due to kitchen, washroom and toilet Deng Yongshui positions, so upper and lower conduit does not get the sun daytime, is more easy to freeze in pipe yet, water pipe is more easy to by bursting by freezing. In view of the foregoing, solar water pipe freezes to have become a universal phenomenon.

Current solutions: it is exactly to install a miniature electric heater in the bottom of upper and lower conduit to prevent upper and lower conduit from freezing and thawing. Electric heater is connected when the same day is cold, then the water by water heater is heated up. Because more than 4 DEG C, the light specific gravity of hot water, the ratio of cold water is great, so hot water can rise, cold water can decline, and form circulation, and last whole upper and lower conduit is just all heated, without freezing. If frozen in pipe, because hot water constantly rises, ice can be made constantly to melt, finally make ice in pipe all fusing and it is unimpeded, then cut off electric heater, then the water in water tank is all bled off, be frozen with guard tube and split. Because the quantity of upper and lower conduit reclaimed water is few, so power consumption will not be big. It is conventional antifreeze: when fine day temperature is less than 0 DEG C, daily preferably repeatedly, it is a small amount of discharge water to use increase pipe temperature, temperature is more low more wants duty to put, with guard tube frozen block. Drip antifreeze: after be finished hot water in the evening, by water tank filling up water, a basin or bucket are then placed under water heater tap, hot water valve is unclamped a bit, it is slowly dripped, to keep managing the flowing of interior water, can so avoid pipe freezeup. Emptying is antifreeze: after being finished water every night, water heater is vented, morning next day adds appropriate water, and this is also a kind of method for preventing pipe freezeup. Once pipeline frozen block need not also worry, can automatic dredging after pipeline after temperature rise. But multiple frozen block will influence the service life of pipeline, easily make frost crack pipe. Heat-insulation layer is antifreeze: the special-purpose thermal insulation pipe of the most handy thickening of the water pipe of water heater encloses, and can so resist certain severe cold.

The content of the invention

The technical problems to be solved in the utility model there is provided a kind of anti-freezing solar water heater of simple structure.

The technical solution of the utility model is: a kind of anti-freezing solar water heater, it is characterized in that being connected with controller and water pipe on the attemperater of solar water heater, attemperater, water tank three-way magnetic valve, emptying solenoid valve and entering water electromagnetic valve are connected with the controller; Water inlet pipe connects water mixing valve and entering water electromagnetic valve respectively, and water mixing valve is also respectively connected with uses shower nozzle and water tank three-way magnetic valve, the entering water electromagnetic valve other end to be connected on water tank three-way magnetic valve; The water tank three-way magnetic valve other end is connected on attemperater, and emptying solenoid valve, emptying solenoid valve other end connection emptying pipeline are connected between water tank three-way magnetic valve and entering water electromagnetic valve.

The controller of the utility model anti-freezing solar water heater is provided with the control button of solar water heater, the opening and closing of the corresponding programme-control water tank three-way magnetic valve of control button, emptying solenoid valve and entering water electromagnetic valve.

The emptying valve outlet of the utility model anti-freezing solar water heater places basin, the water of emptying can be used for his use every time, water resource waste will not be produced, usual bathing, the cold water gone out from shower nozzle is wasted, and after using this programme anti-freeze solar, shower nozzle water out is opened every time and is the hot water for meeting user's request; It is usually anhydrous in the pipe of the utility model anti-freezing solar water heater, therefore antifreeze effect is served, do not interfere with and use the phenomenon with frostbite pipeline; The emptying mode of the utility model anti-freezing solar water heater is automatic intelligent control, and without artificial emptying, stability is strong; The entirety that improve solar water heater uses quality. This kind of mode does not need the pipe insulating layer that current solar water heater is installed additional, reduces installation difficulty, also saves cost.

The utility model anti-freezing solar water heater antifreeze function realization principle is: when cistern water level is less than 20%, now opens the vertical direction of water tank three-way magnetic valve 3, lateral atmospheric valve is closed, entering water electromagnetic valve 6 is opened, and emptying solenoid valve 4 is closed. When adding water to cistern water level to 100%, the vertical direction of water tank three-way magnetic valve 3 is closed, and lateral atmospheric valve is opened, and entering water electromagnetic valve 6 is closed, and emptying solenoid valve 4 is opened, by the water total number emptying in water pipe; When user presses on controller 2 " a key hot water/open ", emptying solenoid valve 4, entering water electromagnetic valve 6 are closed, and the vertical direction of water tank three-way magnetic valve 3 is opened, and lateral atmospheric valve is closed, hot water and running water are adjusted through water mixing valve in attemperater, then through gondola water faucet outflow for bathing. When bathing is finished, water mixing valve is closed, press on controller 2 " a key hot water/pass " key, the vertical direction of water tank three-way magnetic valve 3 is closed, and lateral atmospheric valve is opened, and entering water electromagnetic valve 6 is closed, 4 time delay of emptying solenoid valve is opened after 1 minute, by the water total number emptying in pipeline. .
