Abstract
The utility model discloses a water conserving device used for a water heater, comprising a water heater, a hot water pipeline, a cold water pipeline and a hot water tap. The utility model is characterized in that the device also comprises a check valve which is arranged on the cold water feeding pipeline of the water heater, a water flow switch provided with a temperature controller and a solenoid valve which are connected in series between a hot water outlet and the hot water tap of the water heater; a pump and a check valve are connected in series in a water returning pipeline, a water inlet end of which is connected between the solenoid valve and the water flow switch provided with the temperature controller and a water draining end thereof is connected between the check valve of the cold water pipeline and the cold water inlet of the water heater. The utility model has simple structure, low manufacturing cost and remarkable water conserving effect.
Description
Technical field
The utility model designs a kind of water saving fixtures, the particularly a kind of and matching used water saving fixtures of water heater.
Background technology
Existing water heater comprises two kinds of storage-type electric water heater and instant heating types, and wherein the user of instant heating type water heater is in the majority.In the use, there is following problem in the instant heating type water heater: because export to distance with the hot water tap in water spot such as shower, kitchen etc. from water heater, generally have several meters to tens meters, when using water heater, at first to bleed off the cold water in this depot siding, just can emit hot water and use.So hot water of every use will be wasted about 10 liters or more running water.China is the country of a lack of water, and water resource is quite valuable, and China is again a populous country, so water conservation will be from each family and individual's dribs and drabs.So the problems referred to above of water heater become a problem being badly in need of solution.In order to address this problem, there is the people also to propose some solutions and applied for patent.It is too complicated that but the problem that this solution exists is a structure, and cost is also increased thereupon.
Summary of the invention
The purpose of this utility model is the defective that overcomes above-mentioned prior art, and provides a kind of simple in structure, the water saving fixtures of water heater with low cost.
In order to realize the above object, the technical scheme below the designer has proposed: the water saving fixtures of the water heater of this programme are the same with prior art, comprise water heater, hot water piping, cold line and hot water tap, and its improved part is also to comprise:
A check-valves, this check-valves are contained in the cold water inlet line of water heater;
The water flow switch of a band temperature controller, a magnetic valve, they are serially connected between the hot water outlet and hot water tap of water heater;
A water pump and a check-valves, they are serially connected in the return piping, and the water inlet end of this return piping is connected between the water flow switch and magnetic valve of band temperature controller, and its water side is connected between the cooling water inlet of check-valves in the cold line and water heater.
During use, at first open shower or hot water tap, the water flow switch of band temperature controller is opened, temperature controller control closed electromagnetic valve is controlled water pump operation simultaneously, and the cold water of storing in the pipeline is back in the water heater by return piping and check-valves under the drive of water pump and heats, when treating that water temperature reaches the temperature of setting, temperature controller control water pump is out of service, and magnetic valve is opened simultaneously, and the water that shower or hot water tap come out is hot water.After finishing using, close shower or hot water tap, water flow switch is closed, and water pump is out of service, and magnetic valve is opened.
The beneficial effects of the utility model are, and are simple in structure, with low cost, and water-saving result is fairly obvious.
In order to make the utility model be convenient to understand, it is described further below by drawings and Examples with more clear.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model.
The specific embodiment
Referring to Fig. 1.The water saving fixtures of present embodiment comprise water heater 1, hot water piping 2, cold line 12 and hot water tap 6,7,8.Also have in addition; A check-valves 13, this check-valves 13 are contained in the cold water inlet line 12 of water heater 1; 4, one magnetic valves 5 of the water flow switch of a band temperature controller 3, they are serially connected between the hot water outlet 21 and hot water tap 6,7,8 of water heater 1; A water pump 10 and a check-valves 11, they are serially connected in the return piping 9, the water inlet end 91 of this return piping 9 is connected between the water flow switch 4 and magnetic valve 5 of band temperature controller 3, and its water side 92 is connected between the cooling water inlet 121 of check-valves 13 in the cold line 12 and water heater 1.
