Abstract
A cold water recovering device for a solar water heater comprises a water storage tank and a control circuit box matched with the water storage tank, wherein, an inlet of the water storage tank is connected with a hot water pipe outlet of a solar water heater; the inlet of the water storage tank is provided with a normally closed electromagnetic valve; a water level controller correspondingly comprising an upper water level normally closed contact is also arranged on the water storage tank; a control switch and a time relay are serially connected between two power contact points of the control circuit box; a normally opened contact of the time relay and the normally closed electromagnetic valve as well as the upper water level normally closed contact are also serially connected between the two power contact points. The utility model can recover the cold water released from the hot water pipe before the solar water heater is used, which saves water without waste, and is convenient to install and used.
Description
Technical field: the utility model relates to a kind of and the matched cold water retracting device of solar water heater.
Background technology: solar water heater generally is installed in the roof, and hot-water line leads to the distance of toilet from the roof long, and with the cold water of wanting before the hot water in the first exhausting pipeline, the water yield of waste is more, does not meet present water saving trend at every turn.
Summary of the invention: the utility model is to solve the problem that ducted cold water is all wanted the emptying waste at every turn, and a kind of solar water heater cold water retracting device of recyclable cold water is provided.
The utility model comprises storage tank and supporting control circuit box, the import of storage tank connects the hot-water line outlet of solar water heater, the import of storage tank is provided with normally closed solenoid valve, also be provided with water level controller on the storage tank, its corresponding water level normally-closed contact that contains, be in series with the gauge tap and the time relay between two power supply contacts of control circuit box, the normally opened contact of this time relay and normally closed solenoid valve and last water level normally-closed contact also are connected between two power supply contacts.
Before using hot water, press gauge tap earlier, by the effect of the time relay and corresponding normally opened contact, the normally closed solenoid valve energising of storage tank import is opened the several seconds, the cold water that hot-water line is emitted enters storage tank and stores for other purposes, and water saving is not wasted, and installs and uses more convenient yet.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is the syndeton schematic diagram of embodiment.
Embodiment: as shown in the figure, storage tank 1 is supporting the control circuit box, and the import of storage tank 1 is provided with normally closed solenoid valve 2, and connects hot-water line 6 outlets of solar water heater.Also be provided with water level controller J2 on the storage tank 1, its corresponding water level normally-closed contact J2-1 that contains.Between two power supply contact A of control circuit box and B, be in series with gauge tap K and time relay J1, the normally opened contact J1-1 of this time relay J1 and normally closed solenoid valve 2 and go up water level normally-closed contact J2-1 and also be connected between two power supply contact A and the B.When using hot water, press gauge tap K ON time relay J 1 earlier, normally opened contact J1-1 conducting is like this opened normally closed solenoid valve 2, and the cold water that hot-water line 6 is emitted enters storage tank 1.The conduction time of time relay J1 is adjustable, is generally the several seconds to get final product, and normally closed solenoid valve 2 power-failure close is again opened the tap of hot-water line 6 outlets more then, can use hot water.If the water that storage tank 1 stores reaches certain amount, water level controller J2 can make water level normally-closed contact J2-1 open, and normally closed solenoid valve 2 just can't be switched on and be opened into water like this, avoids excessive the overflowing of water of storage tank 1.
Because the more water closet that is used for of the water that reclaims in the family is washed by water, storage tank 1 can be contained in the position that is higher than toilet flush, the outlet of storage tank 1 connects the water box of water closet import by check-valves 3, the import of toilet flush is connected with the running water pipe 5 of normally open solenoid valve 4 simultaneously, the also corresponding water level normally opened contact J2-2 down that contains of water level controller J2, itself and normally open solenoid valve 4 are connected between the power supply contact A and B of control circuit box.As long as in the storage tank 1 water is arranged, water level controller J2 can make down water level normally opened contact J2-2 energising closed, and the normally open solenoid valve 4 of running water pipe 5 is also closed like this, toilet flush is earlier from storage tank 1 water intaking, after storage tank 1 emptying, normally open solenoid valve 4 just cuts off the power supply and often opens, and running water pipe 5 supplies water.When running water pipe 5 supplied water, check-valves 3 can prevent that part of running water from can pour in down a chimney and go into from the outlet of storage tank 1.
Claims (2)
