Description
Technical field
The present invention relates to the 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 to connect a cold water inlet that is connected with running water pipe, then connect a hot water outlet pipe for emitting hot water; When mounted, occur in order to prevent gas leakage or electric leakage accident, usually spaced apart water heater and bathroom, store the cold water that can't be heated by water heater in hot water outlet pipe therebetween; Need certain preheating time when heating up water due to water heater, cold water can not be heated in moment, so water heater in use, open for the first time hot-water switch or hot-water switch is closed after when again opening, the capital is first flowed a little while and is flowed out hot water after cold water again, and the cold water that flows out is bled off mostly in vain, causes the waste of water resource.After rough Statistics, water heater are opened hot-water switch for the first time, from cold water to the hot water that proper temperature is arranged, during probably have six premium on currency to be wasted; Open again hot-water switch after closing hot-water switch a little while, from cold water to the hot water that proper temperature is arranged, during probably have two premium on currency to be wasted.Because domestic water is frequent, if the factor of consideration time and number of users, the water yield of waste is huge.Although in used vessel will be managed, remaining water is collected and utilized with water saving, implement trouble.
Summary of the invention
The purpose of this invention is to provide a kind of water-saving device of water heater, it can be after hot-water switch be opened, cold water in the hot water outlet pipe is recovered in water heater reheats, flow out hot water when the water in the 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 that is communicated with hot water outlet pipe and cold water inlet in housing, be located at the water blockoff piston in return pipe, solenoid and magnet with water blockoff piston one end is connected are connected to the spring between case top and magnet, are 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 controller that is electrically connected to water pump, temperature sensor and solenoid; Described water blockoff piston is provided with hot water via hole and L shaped cold water via hole, the water blockoff piston can be at the backwater in-pipe under the drive of magnet, the hot water via hole can be communicated with the hot water outlet pipe with hot water outlet, L shaped cold water via hole can be communicated with by return pipe the hot water outlet pipe with cold water inlet.The PLC controller controls solenoid power on/off and pump working/cut out according to the temperature of water in the hot water outlet pipe.
Further, the diameter of described hot water via hole equates with hot water outlet pipe's internal diameter, and the diameter of described L shaped cold water via hole also equates with hot water outlet pipe's internal diameter.
its operation principle is as follows: the hot-water switch of opening water heater, running water enters in water heater from cold water inlet and heats, and flow out from the hot water outlet pipe, temperature sensor detects the temperature of water in the hot water outlet pipe, signal is passed to the PLC controller, if the temperature that in the hot water outlet pipe, the temperature of water is set lower than the PLC controller, the PLC controller is controlled the solenoid energising, magnet moves up, Compress Spring, and drive water blockoff piston moves up, the water blockoff piston cuts off hot water outlet pipe and hot water outlet, the hot water outlet pipe is passed through L shaped cold water via hole, return pipe is communicated with cold water inlet, the PLC controller is controlled pump working, water enters in water heater by cold water inlet and reheats, carrying out along with heating, if the temperature that the temperature of water equals or sets higher than the PLC controller in the hot water outlet pipe, the PLC controller is controlled the solenoid outage, magnet is under the elastic force and self gravitation effect of spring, moving down drive water blockoff piston moves down, the hot water via hole of water blockoff piston is communicated with the hot water outlet pipe with hot water outlet, water flows out from hot water outlet, and the PLC controller controls water pump and cuts out.
The present invention can be after hot-water switch be opened, and the cold water in the hot water outlet pipe is recovered in water heater reheat, and flows out hot water when the water in the hot water outlet pipe reaches proper temperature, and is little on the water heater impact, avoided the waste of water resource, saved water; It is simple in structure 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.
