Background technology
At present, water heater is is extensively installed and used by people as a kind of common household electrical appliance, conventional water heater comprises a cooling water inlet and hot water outlet, hot water outlet is connected with water end (W.E.) with user by water pipe, as tap, bathing spraying etc., present family is in the time installing water heater, due to reasons such as the structures in house, the pipeline often using is longer, water heater from user with water end (W.E.) away from, therefore in the time not using water heater, hot water outlet and user have a large amount of pipeline cold water with the pipeline between water end (W.E.), in the time that need to using hot water, user must first put the water of a period of time, after draining, ducted cold water just can use, increase the time of waiting for water, simultaneously serious waste water resource.In order to address this problem, the way that existing hot water cyclesystem is taked is conventionally: in system, increase the devices such as water pump, temperature sensor, water flow detector, also need to install circulating line.The hot water cyclesystem installation process complexity of this structure, cost is larger, and the space taking is larger, and inconvenience is installed.
Utility model content
For above technical problem, the utility model provides a kind of hot water simple in structure, with low cost, easy for installation pre-circulating valve, can not need spended time to wait for for user provides hot water timely, simultaneously can saving water resource.
The utility model is to realize by such technical scheme, it comprises water heater, on water heater, be connected with respectively hot-water line and cold water pipe, it also comprises the pre-circulating valve of hot water, the pre-circulating valve of hot water is arranged between hot-water line and cold water pipe, the hot water outlet of water heater is connected with one end of the pre-circulating valve of hot water by hot-water line, and the cooling water inlet of water heater is connected with the other end of the pre-circulating valve of hot water by cold water pipe and threeway, on the pre-circulating valve of hot water, is provided with controller.
In the time that water heater does not use, water in hot-water line can be cooling, open the pre-circulating valve of hot water, cold water in hot-water line just can flow in cold water pipe by the pre-circulating valve of hot water, hot water in water heater can be taken advantage of a situation and be flowed in hot-water line, meanwhile, pressure in water heater can reduce along with the outflow of hot water, water in cold water pipe just can enter water heater, cold water in hot-water line flows into water heater after by cold water pipe again, finally after the cold water in hot-water line all flows out, in hot-water line, fill hot water, user just can directly use in the time that needs use hot water like this, and do not need first to put the water of a period of time, reduce user's stand-by period, saved a large amount of water resources simultaneously.Controller can play the effect of automatic control, because each user's water supply network length is different, need the time of circulation also different, therefore in the time installing for the first time, need to set according to the actual conditions of pipeline the control time of controller, after the cold water in water heater all flows into cold water pipe, controller cuts out automatically, water in hot-water line can not flow into cold water pipe again, realize automation control by controller, avoid the cold water of user in hot-water line repeatedly to measure the temperature of current before flowing to end, the utility model is simple in structure, easy for installation, cost of manufacture is cheap, only need in the time installing for the first time, regulate controller, can relievedly use.
The beneficial effects of the utility model are: it has feature simple in structure, with low cost, easy for installation, by increase, a pre-circulating valve of hot water is set, can for providing hot water, user not need spended time to wait for timely, and simultaneously can saving water resource.
Except object described above, feature and advantage, the utility model also has other object, feature and advantage.With reference to the accompanying drawings in the face of the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is principle schematic of the present utility model;
Wherein: 1-water heater, 2-hot-water line, 3-cold water pipe, the pre-circulating valve of 4-hot water, 5-threeway, 6-controller, 7-water pump, 8-check-valves, 9-anti-reflux valve, 10-mixes water valve.
Detailed description of the invention
Below in conjunction with specific embodiment, concrete technical scheme of the present utility model is elaborated.
The utility model comprises water heater 1, on water heater 1, be connected with respectively hot-water line 2 and cold water pipe 3, it also comprises the pre-circulating valve 4 of hot water, the pre-circulating valve 4 of hot water is arranged between hot-water line 2 and cold water pipe 3, the hot water outlet of water heater 1 is connected by one end of the pre-circulating valve 4 of hot-water line 2 and hot water, the cooling water inlet of water heater 1 is connected with the other end of the pre-circulating valve 4 of hot water by cold water pipe 3 and threeway 5, on the pre-circulating valve 4 of hot water, is provided with controller 6.
In the time that water heater 1 does not use, water in hot-water line 2 can be cooling, open the pre-circulating valve 4 of hot water, cold water in hot-water line 2 just can flow in cold water pipe 3 by the pre-circulating valve 4 of hot water, hot water in water heater 1 can be taken advantage of a situation and be flowed in hot-water line 2, meanwhile, the pressure that water heater is 1 li can reduce along with the outflow of hot water, the water that cold water pipe is 3 li just can enter water heater 1, cold water in hot-water line 2 flows into water heater 1 after by cold water pipe 3 again, finally after the cold water in hot-water line 2 all flows out, in hot-water line 2, fill hot water, user just can directly use in the time that needs use hot water like this, and do not need first to put the water of a period of time, reduce user's stand-by period, saved a large amount of water resources simultaneously.Controller 6 can play the effect of automatic control, because each user's water supply network length is different, need the time of circulation also different, therefore in the time installing for the first time, need to set according to the actual conditions of pipeline the control time of controller 6, after the cold water in water heater 1 all flows into cold water pipe 3, controller 6 cuts out automatically, water in hot-water line 2 can not flow into cold water pipe 3 again, realize automation control by controller 6, avoid the cold water of user in hot-water line 2 repeatedly to measure the temperature of current before flowing to end, the utility model is simple in structure, easy to operate, cost of manufacture is cheap, only need in the time installing for the first time, regulate controller, can relievedly use.
In the pre-circulating valve 4 of described hot water, be provided with water pump 7 and check-valves 8, water pump 7 is arranged on the interior one end near hot-water line 2 of the pre-circulating valve 4 of hot water, and check-valves 8 is arranged in the connecting pipe of the interior connection water pump 7 of the pre-circulating valve 4 of hot water and cold water pipe 3.
When use, start water pump 7, the water that hot-water line is 2 li flows to cold water pipe 3 by water pump 7 superchargings, and the pressure of 1 li of water heater is along with the outflow of hot water is lowered, the water that cold water pipe is 3 li is taken advantage of a situation and is just entered water heater 1, so just can reach the object of circulation, in domestic water supply system, the pressure that hot-water line is 2 li is often lower slightly than 3 li of cold water pipes, returns only valve 8 and can avoid cold water to flow to 2 li of hot-water lines.
On the cold water pipe 3 between threeway 5 and water heater 1, be provided with anti-reflux valve 9.Anti-reflux valve 9 can prevent cold-water reflux, makes cold water can only keep flowing of a direction and affects, and flows into water heater 1 from cold water pipe 3, ensures the normal use of system.
The pre-circulating valve 4 of described hot water is connected with mixed water valve 10 by outlet conduit.User can control water temperature by regulating mixed water valve 10, the devices such as mixed water valve 10 can connected with water faucet, shower nozzle.
