Abstract
The utility model relates to a water-saving water heater, which comprises a water heater which is connected with a cold water pipe and a hot water pipe, which are connected with a tap water pipe, and is characterized by also comprising a two-way valve, a booster pump and a check valve; the water inlet end of the two-way valve is connected with the hot water pipe, one water outlet end of the two-way valve is connected with a hot water consuming unit, the other water outlet end of the two-way valve is connected with the input end of the booster pump, and the output end of the booster pump is connected with the cold water pipe; and the check valve is arranged on the door-entrance position of the tap water pipe. The water-saving water heater adopts the two-way valve to control water flow in the pipeline, so water flow with temperature which cannot reach the requirement can be controlled to flow back to the cold water pipe to be heated again, and then flows out when the water temperature reaches the requirement, so cold water cannot be wasted, and the water is saved; and the water output temperature of the water heater is controllable and the water-saving water heater is convenient to use.
Description
Technical field
The utility model relates to a kind of water saving fixtures, particularly relates to a kind of water saving water heater.
Background technology
Normally used gas heater or electric heater, all be to connect a cold water pipe to link to each other with running water pipe, connect a hot-water line again, cold water from running water pipe enters water heater by cold water pipe, temperature through the heater transient heating of water heater inside is extremely set flows out from hot-water line and uses for the user.But there is a problem: when the user has just opened water heater leading, cold water that to be water heater accumulate to the pipeline between tap that at first flows out and the water that is not heated fully by water heater, this part cold water need bleed off earlier, just can use hot water, very waste, simultaneously, leaving water temperature is uncontrollable, makes troubles to life.
Summary of the invention
The purpose of this utility model promptly provides a kind of water saving water heater, opens the back instant-heating and outlet hot, and it is easy to use again promptly to have saved water.
For solving the problems of the technologies described above, the utility model is taked following technical scheme: a kind of water saving water heater, comprise water heater, described water heater is connected with cold water pipe and the hot-water line that links to each other with running water pipe, it is characterized in that, also comprise a two-way valve, a booster pump and a non-return valve, the water inlet end of described two-way valve links to each other with described hot-water line, arbitrary water side of described two-way valve links to each other with water heater, another water side of described two-way valve links to each other with the input of described booster pump, and described supercharging delivery side of pump links to each other with described cold water pipe; Described non-return valve is arranged on the described running water pipe place of registering one's residence.
Preferably, described two-way valve is a magnetic valve.
Preferably, the hot-water line between described water heater and described two-way valve is provided with a temperature inductor, and described temperature inductor connects a control piece, and described control piece is controlled the path direction of described two-way valve.
Water saving water heater of the present utility model adopts the current in the two-way valve control piper, and the current that make temperature not reach requirement return cold water pipe and reheat, and treat to flow out from hot-water line when water temperature reaches requirement again, can not allow cold water be bled off in vain, thereby save water; The water heater leaving water temperature is controlled, and is easy to use.
Description of drawings
Fig. 1 is the schematic diagram of a kind of water heater preferred embodiment of economizing on water of the present utility model.
1-water heater among the figure, 2-hot-water line, 3-running water pipe, 4-cold water pipe, 5-temperature inductor, 6-two-way valve, 7-booster pump, 8-non-return valve.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 1, a kind of water saving water heater, comprise water heater 1, water heater 1 is connected with cold water pipe 4 and the hot-water line 2 that links to each other with running water pipe 3, also comprise a two-way valve 6, a booster pump 7 and a non-return valve 8, the water inlet end of two-way valve 6 links to each other with hot-water line 2, and arbitrary water side of two-way valve 6 links to each other with water heater, another water side of two-way valve 6 links to each other with the input of booster pump 7, and the output of booster pump 7 links to each other with cold water pipe 4; Non-return valve 8 is arranged on running water pipe 3 place of registering one's residence.
Two-way valve 6 is a magnetic valve.
The hot-water line 2 that water heater 1 and two-way valve are 6 is provided with a temperature inductor 5, and temperature inductor 5 connects a control piece (not shown), and control piece is controlled the path direction of two-way valve 6.
During use, open the tap of water heater, the water in the water pipe begins to flow, water heater 1 is lighted a fire automatically, the temperature that temperature inductor 5 is sensed in the hot-water line 2 is lower than design temperature, and the control piece of connection is controlled two-way valve 6, is disconnected to the passage of water heater, flow to booster pump 7, under the pressurization of booster pump 7, current flow back to cold water pipe 4, enter heating again in the water heater 1, non-return valve 8 on the running water pipe 3 prevents that current from flowing into home-in-pipe, pollutes; When temperature inductor 5 is sensed temperature in the hot-water line 2 and is equaled design temperature, the control piece control two-way valve 6 of connection, be switched to water heater passage, hot water flows out.
The above only is a better embodiment of the present utility model; protection domain of the present utility model does not exceed with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
