Description
Technical field
The present invention relates to water heater optional feature, be specifically related to a kind of water-saving device of water heater.
Background technology
Normally used gas water heater or Electrothermic water heater are all connection cold water inlets be connected with running water pipe, then connect a hot water outlet pipe for releasing hot water; When mounted, in order to prevent gas leakage or electric leakage accident occur, usually water heater and bathroom spaced apart, store the cold water that cannot be heated by water heater in hot water outlet pipe therebetween; Owing to needing certain preheating time when water heater is heated up water, cold water can not be heated in moment, so water heater in use, when opening hot-water switch for the first time or again open after hot-water switch is closed, capital is first flowed and is flowed out hot water again after cold water a little while, and the cold water flowed out is bled off mostly in vain, cause the waste of water resource.Rough Statistics, after water heater opens hot-water switch for the first time, from cold water to the hot water having proper temperature, period probably has six premium on currency to be wasted; Open hot-water switch again after closing hot-water switch, from cold water to the hot water having proper temperature, period probably has two premium on currency to be wasted a little while.Because domestic water is frequent, if the factor of the time of consideration and number of users, the water yield of waste is huge.Although used vessel will manage interior remaining water Collection utilization with water saving, implement and comparatively bother.
Summary of the invention
The object of this invention is to provide a kind of water-saving device of water heater, it can after hot-water switch be opened, cold water in hot water outlet pipe is recovered in water heater and reheats, flow out hot water when the water in hot water outlet pipe reaches proper temperature, avoid the waste of water resource.
Water-saving device of water heater of the present invention, comprise housing, be located at the return pipe be communicated with cold water inlet with hot water outlet pipe in housing, be located at the water blockoff piston in return pipe, the solenoid be connected with water blockoff piston one end and magnet, be connected to the spring between case top and magnet, is connected to the water pump on cold water inlet, be positioned at the temperature sensor on the hot water outlet pipe of housing, the PLC be electrically connected with water pump, temperature sensor and solenoid; Described water blockoff piston is provided with hot water via hole and L shape cold water via hole, water blockoff piston can at backwater in-pipe under the drive of magnet, hot water outlet pipe can be communicated with hot water outlet by hot water via hole, and hot water outlet pipe can be communicated with cold water inlet by return pipe by L shape cold water via hole.PLC controls solenoid power on/off and pump working/closedown according to the temperature of water in hot water outlet pipe.
Further, the diameter of described hot water via hole is equal with the internal diameter of hot water outlet pipe, and the diameter of described L shape cold water via hole is also equal with the internal diameter of hot water outlet pipe.
Its operation principle is as follows: the hot-water switch opening water heater, running water enters in water heater from cold water inlet and heats, and flow out from hot water outlet pipe, temperature sensor detects the temperature of water in hot water outlet pipe, signal is passed to PLC, if the temperature that in hot water outlet pipe, the temperature of water sets lower than PLC, then PLC controls solenoid energising, magnet moves up, Compress Spring, and drive water blockoff piston to move up, hot water outlet pipe and hot water outlet cut off by water blockoff piston, by hot water outlet pipe by L shape cold water via hole, return pipe is communicated with cold water inlet, PLC controls pump working, water is entered in water heater by cold water inlet and reheats, along with the carrying out of heating, if the temperature that in hot water outlet pipe, the temperature of water equals or sets higher than PLC, then PLC controls solenoid power-off, magnet is under the elastic force and self gravitation effect of spring, move down and drive water blockoff piston to move down, hot water outlet pipe is communicated with hot water outlet by the hot water via hole of water blockoff piston, and water flows out from hot water outlet, and PLC controls water pump and closes.
Cold water in hot water outlet pipe after hot-water switch is opened, can be recovered in water heater and reheats by the present invention, flows out hot water when the water in hot water outlet pipe reaches proper temperature, little on water heater impact, avoids the waste of water resource, has saved with water; Its structure is simple simultaneously, does not need in use to change the original structure of water heater, and easy to operate, cost is low, has good promotional value.
Accompanying drawing explanation
Fig. 1 is the view (arrow represents water (flow) direction) that in the present invention, hot water outlet pipe is communicated with cold water inlet by L shape cold water via hole, return pipe.
Fig. 2 is the view (arrow represents water (flow) direction) that in the present invention, hot water outlet pipe is communicated with hot water outlet.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Water-saving device of water heater as shown in Figure 1 and Figure 2, comprise housing 1, be located at the return pipe 8 be communicated with cold water inlet 7 with hot water outlet pipe 5 in housing 1, be located at the water blockoff piston 3 in return pipe 8, the solenoid be connected with water blockoff piston 3 one end and magnet 2, be connected to the spring 11 between housing 1 top and magnet 2, be connected to the water pump 10 on cold water inlet 7, be positioned at the temperature sensor 4 on the hot water outlet pipe 5 of housing 1, the PLC 9 be electrically connected with water pump 10, temperature sensor 4 and solenoid; Water blockoff piston 3 is provided with hot water via hole 31 and L shape cold water via hole 32, and the diameter of hot water via hole 31 is equal with the internal diameter of hot water outlet pipe 5, and the diameter of L shape cold water via hole 32 is also equal with the internal diameter of hot water outlet pipe 5,
