The specific embodiment
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
The present invention relates to a kind of water-saving system for water heater, be mainly connected on the hot-water line of water heater 1, on this hot-water line 1, along water outlet direction, be provided with successively the first connecting position 11, the second connecting position 12 and the 3rd connecting position 13 for connecting for water-saving system.
Shown in Fig. 1-3, water-saving system mainly comprises water tank 30, the first negative pressure water-absorption mechanism 31, temperature-sensing element 32, the first magnetic valve 33, the second magnetic valve 34, the first negative tube 35, trap 36, the second negative pressure water-absorption mechanism 37, the second negative tube 38 and control box 39.
Described the first negative pressure water-absorption mechanism 31 is arranged on the first connecting position 11 communicatively, and the negative pressure mouth 3113 of this first negative pressure water-absorption mechanism 31 connects better water tank 30 sides that are connected to of water tank 30(by bottom position via the first negative tube 35).The first negative tube 35 is provided with the first check valve, provides this first check valve in embodiment and is arranged on the position (not shown) that water tank 30 is connected with the first negative tube 35, and the first check valve is used for controlling water tank 30 toward the unidirectional water outlet of the first negative tube 35.On water tank 30, offer atmospheric pressure opening 301, better this atmospheric pressure opening 301 is located at the top of water tank 30, supplies spilling water effect as gap simultaneously.
Described temperature-sensing element 32 is preferably sensing rod for temperature, and it is located at the second connecting position 12 places, stretches in hot-water line 1 temperature through water herein for induced flow.The second connecting position 12 is connected to water tank 30, the first magnetic valves 33 via trap 36 and is arranged on (preferably near the second connecting position 12 positions installations) on trap 36.The second connecting position 12 is positioned at the position, water side near hot-water line 1, to guarantee that the cold water energy major part in hot-water line 1 is collected into water tank 30.The second magnetic valve 34 is arranged on the 3rd connecting position 13, and temperature-sensing element 32, the first magnetic valve 33 and the second magnetic valve 34 are electrically connected to respectively the control end of control box 39.
Before work, by operating control box 39 to preset the leaving water temperature that hot-water line 1 is minimum.During use, open water heater tap to go out warm water, water temperature by temperature-sensing element 32 induction heat water pipe 1 interior water, afterwards by influence value automatic feedback to control box 39, when control box 39 detection water temperatures do not reach preset temperature, control box 39 is controlled the first magnetic valve 33 and is opened, control the second magnetic valve 34 closes simultaneously, thus, the water side of hot-water line 1 is cut off, the interior initial cold water of hot-water line 1 flows into water tank 30 via trap 36, now water outlet of water heater mechanism water outlet hardly, initial cold water part in hot-water line 1 is collected by water tank 30, realize water saving effect.
Afterwards, initial cold water part in hot-water line 1 is drained, current in hot-water line 1 are the warm water of water heater after heating, now temperature-sensing element 32 detection water temperatures reach after preset temperature, with reason control box 39, controlling the first magnetic valve 33 closes, control the second magnetic valve 34 simultaneously and open, now the water inlet end of trap 36 is cut off, and the warm water in hot-water line 1 causes its water side along its pipeline and realizes water outlet.
Along with the interior warm water of hot-water line 1 continue to flow through, water tank 30 can also be realized automatic negative-pressure water outlet.Particularly, water tank 30, by its atmospheric pressure opening 301, makes its inner water be subject to atmospheric pressure effect, and water tank 30 connects the first negative pressure water-absorption mechanism 31 via negative tube 35.High-velocity flow in hot-water line 1 is during via the first negative pressure water-absorption mechanism 31, by high-velocity flow effect, in negative pressure mouth 3113 sides, will produce negative pressuren zone, by this suction function, the cold water in water tank 30 is drawn in hot-water line 1 via negative tube 35, with this, realizes the automatic cycle utilization of the cold water of water tank 30 interior collections.
Preferably, in order to promote the cycle efficieny of water tank 30 inner cold waters, water-saving system also extends on the cold water pipe 2 that is connected to water heater, and water-saving system also comprises the second negative pressure water-absorption mechanism 37 and the second negative tube 38.Cold water pipe 2 is provided with a connecting position 20, the connected mode of the second negative pressure water-absorption mechanism 37 and the second negative tube 38 and the first negative pressure water-absorption mechanism 31 and the first negative tube 35 are in like manner, particularly, the second negative pressure water-absorption mechanism 37 is arranged on connecting position 21, the negative pressure mouth of the second negative pressure water-absorption mechanism 37 connects water tank 30 via described the second negative tube 38, the second negative tube 38 is provided with controls water tank 30 toward the second check valve (not shown) of the second negative tube 38 unidirectional water outlets, the second check valve and described the first one-way valve structures setting in like manner, are not tired out and are stated in detail here.
The operation principle of described the second negative pressure water-absorption mechanism 37 and the second negative tube 38 is identical with the operation principle of the first negative pressure water-absorption mechanism 31 and the first negative tube 35, being equivalent to water tank 30 arranges two-way and goes out water circulation, make full use of hot water pipe high-velocity flow, strengthen the cold water of collecting and effectively recycle in time again.Certainly, it should be noted that here, the first negative pressure water-absorption mechanism 31 is relevant with the water velocity in cold water pipe 2 with corresponding hot-water line 1 with the size of the negative pressure that the second negative pressure water-absorption mechanism 37 produces, and water velocity is larger, and the negative pressure of generation is just larger.
