Abstract
The utility model provides a water-saving device of a water heater. The water-saving device comprises a reflux valve assembly, a circulating pump and a temperature control delay circuit, wherein the reflux valve assembly comprises two one-way valves; the first one-way valve is arranged at an entrance cold water pipe; and the second one-way valve, a temperature controller, a delayer and the circulating pump are sequentially arranged on a hot water pipeline for connecting the water heater and a water tap. On the premise that the conventional pipeline is not changed, the water-saving device of the water heater is arranged on the conventional pipeline, so that waste of cool water can be avoided, the water outlet temperature can be set, and the waiting time of using the hot water is shortened.
Description
Background technology
The utility model provides water-saving device of water heater.
Technical field
At present, family, hotels and other places one be provided with hot water generators such as gas heater, electric heater.But these water heaters exist such problem in use: one, tap has a segment distance apart from water heater, and what at first come out after tap is opened is the cold water that stores in the water pipe, and one has all gone out of use this part cold water.Two, water heater heating cold water itself has one section process, and in this section heating process, water temperature does not reach demand, so the water that flows out also goes out of use.Three, when arctic weather uses water heater, hot water flows out in the pipeline needs the long time, and the trial water temperature that need not stop with hand only meets user's requirement to hot water, like this, has also wasted user's time.
The utility model content
The utility model is in order to overcome the deficiency that existing water heater is wasted water and lost time, under the prerequisite of not changing existing pipeline, only need on existing pipeline, install water-saving device of water heater additional, just can avoid cold water to go out of use, and can set leaving water temperature and shorten the stand-by period of using hot water.
Water-saving device of water heater, it is characterized in that, comprise return valve assembly, circulating pump, temperature control delay circuit, wherein, the return valve assembly comprises two check valves, first check valve is located at the house lead in cold water pipe, and second check valve, temperature controller, delayer and circulating pump are installed on the hot water pipeline that connects water heater and tap successively.
Wherein, also have control device to connect the temperature control delay circuit.
Wherein, described control device can adopt touch or distance type control temperature control delay circuit.
The specific embodiment of the present utility model is asked for an interview and is described below.
Description of drawings
Fig. 1 is the schematic diagram of water-saving device of water heater among the utility model embodiment.
The specific embodiment
Provide preferred embodiment of the present utility model below, these embodiment and unrestricted content of the present utility model.
Embodiment
Ask for an interview shown in Figure 1, the utility model provides water-saving device of water heater, comprise return valve assembly 1, circulating pump 5, temperature control delay circuit 4, wherein, return valve assembly 1 comprises two check valves, first check valve 11 is located on the house lead in cold water pipe 2, and second check valve 12, temperature control delay circuit 4 and circulating pump 5 are installed on the hot-water line 8 that connects water heater 7 and tap 6 successively.Control device 3 connects temperature control delay circuit 4, and control device 3 can adopt touch or distance type control temperature control delay circuit 4.
Workflow of the present utility model is: the user touches down control device 3 and starts water-saving device of water heater, temperature control delay circuit 4 starts, cold water flows into water heater 7 from cold water pipe 2 through first check valve 11,7 pairs of cold water of water heater begin heating, water is in the circulation that does not stop through described water-saving device of water heater from water heater 7 in hot-water line 8 under the driving of circulating pump 5, temperature in temperature control delay circuit 4 detects hot-water line 8 is when knowing clearly temperature default, temperature control delay circuit 4 sends a signal to circulating pump 5 and makes it to quit work, at this moment, be the hot water that the user needs from the tap 6 interior water that flow out.
The utility model is by being provided with two check valves, makes cold water in that to be heated to proper temperature only mobile in the hot-water line 8 in closure earlier, prevents that cold water from mixing with hot water, played water-saving function.Control device 3 can be selected push button or distance type control temperature control delay circuit 4 for use in concrete the application, convenient for users to use like this.
About water heater 7, no matter any be the firing equipment of which kind of form, supportingly reach water-saving effect after going up the utility model as gas heater, electric heater, solar water heater etc. are all available.The aspect, place, family, hotel, hospital etc.The utility model is easy to install and use, can independently install additional voluntarily in the existing pipe-line system, also can with firing equipment as the supporting use of annex.
Claims (3)
1. water-saving device of water heater, it is characterized in that, comprise return valve assembly, circulating pump, temperature control delay circuit, wherein, the return valve assembly comprises two check valves, first check valve is located at the house lead in cold water pipe, and second check valve, temperature controller, delayer and circulating pump are installed on the hot water pipeline that connects water heater and tap successively.
2. water-saving device of water heater as claimed in claim 1 is characterized in that, also has a control device to connect the temperature control delay circuit.
