Description

Water-saving device of water heater
Technical field: the present invention relates to a kind of water-saving device of water heater, it is applicable to gas heater, electric heater, Teat pump boiler, solar water heater etc.
Background technology: the existing and matching used water saving fixtures of water heater adopt water pump to send the cold water in the pipeline to water heater circulation heating more more.The disadvantage of this class device is: the first, and difficult assurance of the time of water pump operation.As adopt hand, use hot water at every turn before, need the artificial water pump that starts earlier, operation is inconvenience very; As adopt temperature induction type, and then no matter whether the user needs hot water, as long as the cold water in the pipeline is lower than start-up temperature, water pump will frequently move, and water heater also can frequent operation, takes electricity charge gas.The second, to exerting an influence in service life of water heater.Adopt water pump to form closed circuit partial circulating and start water heater, because the cold water in the pipeline is less, discharge is very little, (near the situation of dry combustion method) frequent starting water heater heating under the situation of this improper extra small flow, the service life that can reduce water heater.For overcoming these defectives, water-saving device of water heater is developed.
Summary of the invention: technical problem to be solved by this invention is that a kind of water-saving device of water heater will be provided, and it can flow out the cold water in the pipeline earlier effectively and store, and is recovered in the water inlet tube of water heater road again, and does not need additionally to start water heater.
The technical scheme that the present invention solves its technical problem employing is:
It comprises temperature-sensitive triple valve, backwater water inlet pipe, storage tank, backwater outlet pipe, described temperature-sensitive triple valve respectively with water heater in outlet pipe, be communicated with water spot, backwater water inlet pipe, the other end of backwater water inlet pipe is connected with the inlet of storage tank, the outlet of storage tank is connected with backwater outlet pipe one end, the other end of backwater outlet pipe is communicated with water inlet pipe in the water heater, and the temperature-sensitive triple valve is by outlet pipe in the temperature control water heater and with logical the closing between water spot, the backwater water inlet pipe.
Described storage tank comprises expansion tank, check valve, housing, water pump, ball-cock assembly, the inner chamber of housing is divided into reservoir chamber and power house, be provided with ball-cock assembly in reservoir chamber inside, the import of the other end of backwater water inlet pipe and backwater outlet pipe is connected the bottom of reservoir chamber, ball-cock assembly is above the backwater outlet pipe, on the backwater outlet pipe of power house, be respectively equipped with water pump, expansion tank and check valve, and be interconnected.
The upside of described reservoir chamber is provided with spiracle.
The present invention compares the beneficial effect that is produced with background technology:
1, because the present invention adopts the structure of temperature-sensitive triple valve, backwater water inlet pipe, storage tank, backwater outlet pipe, so flowing out the cold water in the pipeline earlier effectively, it stores, be recovered to again in the water inlet tube of water heater road, and do not need additionally to start water heater.
Description of drawings: Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of storage tank 6 among Fig. 1.
Fig. 3 is the annexation figure of the present invention and water heater 17.
The specific embodiment: shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, water valve 1 is arranged on the front of temperature-sensitive triple valve 2 in the present embodiment, temperature-sensitive triple valve 2 connects respectively with water spot 3 and backwater water inlet pipe 7, backwater water inlet pipe 7 other ends are connected on the inlet of storage tank 6, the outlet of storage tank 6 links to each other with backwater outlet pipe 5, and backwater outlet pipe 5 other ends are connected in the water heater 17 on the water inlet pipe 4.
Temperature-sensitive triple valve 2 adopt temperature control valves control water pipes 8 with logical the closing between water spot 3, the backwater water inlet pipe 7, under normal temperature or low-temperature condition, conducting between water pipe 8 and the backwater water inlet pipe 7, the interior temperature control valves of temperature-sensitive triple valve 2 will be with water spot 3 obstructions.At high temperature or surpass under the design temperature state, the temperature control valve expanded by heating in the temperature-sensitive triple valve 2 stops up backwater water inlet pipe 7, with water pipe 8 with water spot 3 conductings.
Storage tank 6 is mainly used in and stores and reclaim cold water, it comprises housing 14, water pump 15, expansion tank 12, check valve 13, ball-cock assembly 16, the inner chamber of housing 14 is divided into reservoir chamber 10 and power house 11, in reservoir chamber 10, the middle part is provided with ball-cock assembly 16, the import of the other end of return pipe 7 and return pipe 5 is connected the bottom of reservoir chamber 10, ball-cock assembly 16 is above return pipe 5, the upside of reservoir chamber 10 is provided with spiracle 9, on the return pipe 5 of power house 11, be respectively equipped with water pump 15, expansion tank 12 and check valve 13, and be interconnected.
When the user opened water valve 1 water, if the water in the water pipe 8 is cold water, temperature-sensitive triple valve 2 was closed with water spot 3, and with water pipe 8 and 7 conductings of backwater water inlet pipe, cold water stores by the reservoir chamber 10 that backwater water inlet pipe 7 flows into storage tank 6.When arriving through the hot water of water heater, temperature-sensitive triple valve 2 is closed backwater water inlet pipe 7, and with water pipe 8 with water spot 3 conductings, hot water uses for the user by with water spot 3 outflows.Temperature-sensitive triple valve 2 has guaranteed that cold water flows away from backwater water inlet pipe 7, and all is hot water from what flow out with water spot 3.
Water storage in storage tank 6 reaches a constant volume, and promptly the water level of reservoir chamber 10 rises to the position of ball-cock assembly 16, and the switch in water pump 15 circuit is connected in ball-cock assembly 16 actions, and water pump 16 is started working, and water storage is imported the water inlet pipe 4 of water heater 17.When the water storage water level drops to a certain degree, ball-cock assembly 16 descends, and disconnects the switch in water pump 15 circuit, and water pump 16 quits work.Ball-cock assembly 16 is according to the operation of the variation automatically controlled water pump 15 of water storage water level, and it is very convenient that this device is operated.The expansion tank 12 of water pump 15 outlets plays the effect of regulating water pressure fluctuations in the pipeline.Check valve 13 guarantees that current can only be flowed by water inlet pipe 4 directions of storage tank 6 to water heater 17.
