Abstract

The invention discloses a temperature control and water conservation circulation device of a solar water heater. The temperature control and water conservation circulation device comprises a cold water pipe (1) used for cold water inputting, and a hot water pipe (2) used for draining hot water. A transverse pipe (3) is arranged at the position, close to an outlet of the hot water pipe (2), of the hot water pipe (2). The cold water pipe (1) and the hot water pipe (2) are communicated through the transverse pipe (3). A water pump (6) is arranged on the transverse pipe (3) and used for pumping water in the hot water pipe (2) into the cold water pipe (1). A first electromagnetic valve (4) is further arranged on the transverse pipe (3). The water pump (6) and the first electromagnetic valve (4) are both connected with a controller (8). Water in the hot water pipe is pumped to the cold water pipe through the water pump, and therefore the hot water pipe can be in the hot water state all the time, water directly drained out of the hot water pipe is hot water when the temperature control and water conservation circulation device is used by users, the transition period during which cold water is drained from the hot water pipe in the use process is avoided, and water resources wasted by people are reduced to a great extent.

Description

A kind of solar water heater temperature control water-saving circulation device
Technical field
The present invention relates to a kind of solar water heater temperature control water-saving circulation device, belong to technical field of solar water heaters.
Background technology
The solar water heater of China all widely uses in city or in rural area, almost relate to every household, the equipment in our life is significantly used in as such one, we but in use have such worry, the very long cold water transitional period all can be had during each use, this makes us can only look at valuable water resource waste helplessly, even if sometimes our choice for use bucket carrys out splendid attire, but very inconvenient all the time.
Therefore, a kind of solar water heater temperature control water-saving circulation device, when not using solar water heater, make to remain hot water conditions in hot-water line, when tap of fetching boiling water uses hot water, what directly release is exactly hot water, without very long cold water transition stage, using water wisely.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of solar water heater temperature control water-saving circulation device, make to remain hot water conditions in hot-water line, when tap of fetching boiling water uses hot water, what directly release is exactly hot water, without very long cold water transition stage, using water wisely.
The object of the invention is to be achieved through the following technical solutions:
A kind of solar water heater temperature control water-saving circulation device, comprise the cold water pipe for entering cold water and the hot-water line for releasing hot water, described hot-water line is provided with a transverse tube near the position of its outlet, described transverse tube is communicated with described cold water pipe and hot-water line, described transverse tube is provided with a water pump for being evacuated in described cold water pipe by the water in described hot-water line, described transverse tube is also provided with the first magnetic valve, and described water pump is connected with controller respectively with the first magnetic valve.Utilize water pump, be evacuated in cold water pipe by water low for temperature in hot-water line, make in hot-water line is hot water conditions always, and time user is used, what hot-water line was directly released is exactly hot water.
Preferably, arrange the second magnetic valve at the exit position place of described hot-water line, the position be connected with transverse tube at described hot-water line is provided with temperature sensor, and described second magnetic valve and temperature sensor are connected with controller respectively.By temperature sensor, form close loop control circuit, the operation of automatically controlled water pump and automatically control the first magnetic valve, the second magnetic valve unlatching with closed.
Preferably, described first magnetic valve is normally closed solenoid valve.
Preferably, described second magnetic valve is normally open type magnetic valve.
Preferably, described controller adopts digitial controller.
Beneficial effect of the present invention is as follows:
1, the present invention utilizes water pump that water low for the temperature in hot-water line is evacuated to cold water pipe, can make to be hot water conditions in hot-water line always, time user uses, what hot-water line was directly released is exactly hot water, when avoiding use, the transitional period of cold water released by hot-water line, decreases our waste to water resource to a great extent;
2, the present invention utilizes temperature sensor and controller to form close loop control circuit, and automatically control the first magnetic valve, the second magnetic valve and water pump, simple to operation, automaticity is high;
3, structure of the present invention is simple, and easy for installation, cost is low.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, invention is described further:
A kind of solar water heater temperature control water-saving circulation device, comprise the cold water pipe 1 for entering cold water and the hot-water line 2 for releasing hot water, described hot-water line 2 is provided with a transverse tube 3 near the position of its outlet, described transverse tube 3 is communicated with described cold water pipe 1 and hot-water line 2, described transverse tube 3 is provided with a water pump 6 for being evacuated in described cold water pipe 1 by the water in described hot-water line 2, described transverse tube 3 is also provided with the first magnetic valve 4, described water pump 6 is connected with controller 8 respectively with the first magnetic valve 4, preferably, described first magnetic valve 4 is normally closed solenoid valve, described controller 5 adopts digitial controller.
In the present embodiment, at the exit position place of described hot-water line 2, the second magnetic valve 5 is set, the position be connected with transverse tube 3 at described hot-water line 2 is provided with temperature sensor 7, described second magnetic valve 5 and temperature sensor 7 are connected with controller 8 respectively, preferably, described second magnetic valve 5 is normally open type magnetic valve.
Operation principle of the present invention is: set in controller 8 using temperature value as setting value, temperature sensor 7 detects the water temperature in hot-water line 2 and data is sent to controller 8, if when detected water temperature is lower than setting value in controller 8, controller 8 sends control signal, second magnetic valve 5 is closed, first magnetic valve 4 is opened, starting water pump 6 is evacuated in cold water pipe by the water in hot-water line 2, until when the water temperature in hot-water line 2 is higher than setting value, controller 8 sends control signal and makes water pump 6 out of service, make the first magnetic valve 4 close simultaneously, second magnetic valve 5 is opened, circulation like this makes hot-water line 2 keep hot water conditions always.
