Abstract

The utility model discloses a novel energy-conserving and water-saving gas water heater, and solves the problem that the discharge of cold water or low-temperature water in the pipe takes a long time, recycles the large amount of water wasted because the water cannot be used due to the low temperature, improves the utilization efficiency of the water heater, and achieves the energy-conserving and water-saving effects (longer the hot water pipe is, more obvious the effect is). The water heater has the advantages of simple structure, convenient use, and high energy-conserving and water-saving efficiencies. A back flow device mainly comprises a thermoswitch, a water pressure sensitive switch, an electromagnetic switch, an electromagnetic directional control valve, a low-power pump and a hydraulic directional control valve. When a water tap is turned on, the water pressure sensitive switch is closed at once, the electromagnetic directional control valve is electrified for changing the direction while the electromagnetic switch is closed, the low-power pump is electrified for increasing the water pressure in a back flow pipe, the hydraulic directional control valve changes the direction under the water pressure in the back flow pipe, and the back flow pipe is communicated with a cold water delivery pipe, and therefore the purpose that the cold water or low-temperature water is automatically recycled is achieved.

Description

Novel energy-conserving water saving water heater
Technical field
The utility model relates to a kind of hot water apparatus of saving domestic water, is particularly useful for the long situation of hot-water line.The water of initial not enough serviceability temperature of discharging in the hot-water line can be recycled, also reduce simultaneously and opened the time of waiting for hot water behind the water heater.Improve service efficiency to a certain extent, saved water resource.
Background technology
Gas heater is a kind ofly can use various sources of the gas such as natural gas, liquefied petroleum gas, artificial coal gas, biogas, provide the Gas appliance of hot water specially, it have easy to use, expense is cheap, quick heating, thermal efficiency advantages of higher, has now become new home auxiliary products.At present, in order to guarantee the easy to use and safety of gas water heater, and the discharging of the flue gas that produces of burning, water heater generally is installed in the kitchen, and using the place of hot water mainly is kitchen, bathroom and toilet.Yet in use, since between water heater and toilet, the bathroom pipe arrangement longer distance is arranged.In this case, the one side water heater need could obtain the hot water of sufficient temp constantly behind certain hour; After using this external last time, a large amount of water of cooling naturally have been detained in this long hot-water line.Therefore, opening hot water tap's switch must need to wait for long period of time, and the hot water that just can obtain sufficient temp behind the interior water of original hot-water line has been drained in the stable heating of heat exchanger by the time simultaneously.In the hot water use, if the user does not reclaim the water of the not enough temperature of these starting stages discharges, can cause the meaningless waste of water resource, if reclaim with bucket, very inconvenience again.And domestic gas formula water heater directly is discharged on the floor, toilet mostly at present, has wasted.
Summary of the invention
Under the most mounting condition of existing domestic gas-fired water heater, hot-water line often from the kitchen to the toilet, makes hot-water line longer.After opening water heater, what hot-water line was discharged in the long period all is that cold water or temperature do not reach the warm water that is suitable for requirement.The water of the not enough temperature of discharging for these under the habits and customs of present most of families, can not be used incipient stages, has wasted.The utility model provides a kind of modified water heater, water heater can not only be recycled the hot-water line inner cold water automatically, reach the effect of energy-saving and water-saving, can also be trapped in hot-water line interior cold water or warm water before the fast evacuation use, thereby the user can obtain hot water more quickly.
The technical scheme that its technical problem that solves the utility model adopts is: install thermoswitch, hydraulic pressure microswitch, solenoid directional control valve and return line in general gas formula water heater pipeline additional.Return line is made of electromagnetic switch, small-power pump and hydraulicchange-over valve.When opening hot water tap's switch, hot water inner pipe water pressure microswitch and temperature-sensitive electric-controlled switch are closure state, the work of switching on simultaneously of electromagnetic switch and solenoid directional control valve.At the water tap end of hot-water line, the commutation of solenoid directional control valve makes the pathway closure that flows to the hot water tap, is communicated with return duct simultaneously; The backflow inner pipe water pressure is increased, cause hydraulicchange-over valve work, make the pathway closure of the thermal treatment zone and running water inlet, be communicated with return duct.Like this, cold water in the hot-water line or water at low temperature are not directly to flow out from tap, but return the thermal treatment zone via reflux line under the effect of pump.Thus, a large amount of water at low temperature that originally can waste all have been used.When the water in the hot-water line reaches design temperature, the thermoswitch automatic disconnection, the pump outage, two valves also reset simultaneously, the water heater operate as normal.
The beneficial effects of the utility model are, when bringing into use, needn't spend to wait as long for the water that hot-water line has flowed not enough serviceability temperature, and these cold water or water at low temperature are all recycled, thereby reach the function of energy-saving and water-saving, and it is simple in structure.
