Specific embodiment
The present invention will be described for following embodiment, but the present invention is not limited to these examples system.To of the invention
Specific embodiment is modified or some technical features can be equivalently replaced, without departing from the spirit of the present invention program,
It should all cover within the scope of the technical scheme claimed by the invention.
As shown in Figures 1 to 3, the present embodiment provides a kind of water-heater systems, including heat exchanger 1, water inlet pipe 2, outlet pipe
3, cold water pipe 4, hot-water line 5 and multiple water spots 6, wherein 2 one end of water inlet pipe is connected with the water inlet end of heat exchanger 1, the other end
It is connected respectively with multiple with water spot 6 by cold water pipe 4,3 one end of outlet pipe is connected with the water outlet of heat exchanger 1, and the other end is logical
It overheats water pipe 5 to be connected with multiple with water spot 6 respectively, the circulating pump 11 connecting with water inlet pipe 2 is provided on heat exchanger 1, also
Including circulation waterway 7, solenoid valve 8, controller and pressure switch 9, wherein in hot-water line 5 and cold water of the distalmost end on water spot 6
Circulation waterway 7 is provided between pipe 4, solenoid valve 8 is arranged in series on circulation waterway 7 for switch cycles water route 7, controller
Respectively with solenoid valve 8, pressure switch 9 be electrically connected, pressure switch 9 be used for detect distalmost end water spot 6 cooling water inlet whether
It is opened, and will test result and feed back to controller, controller is acted according to the signal control solenoid valve 8 fed back and followed with switching
Ring water route 7.
The water heater of the present embodiment, structure is simple, and can effectively avoid water heater, there is a situation where mix water.The present embodiment
Water heater mainly controls the circulation waterway of water heater by pressure switch 9 and solenoid valve 8, thus normal instead of common water heater
Series connection is equipped with the circulation waterway of check valve control water heater on circulation waterway, and then efficiently solves zero cold water water heater
The pain spot of mixed water, has saved the unnecessary consumption of combustion gas.
In the present embodiment, pass through heat exchanger 1, water inlet pipe 2, outlet pipe 3, cold water pipe 4, hot-water line 5, circulation waterway 7
With circulating pump 11 so that water heater constitutes the circulation waterway system of closed type, in this implementation includes multiple with water spot 6, wherein
Distance at right-most position in Fig. 1 and apart from water heater 1 it is farthest be distalmost end water spot 6, circulation waterway 7 with water spot
It is set between the hot-water line 5 with water spot 10 and cold water pipe 4 to be used to open or close circulation waterway 7.It is hot in the present embodiment
Hydrophone is under zero cold water mode, and the work of circulating pump 11 opens simultaneously solenoid valve 8, and the water of 5 the inside of hot-water line is followed by recirculated water
By water inlet pipe 2 toward flowing inside heat exchanger 1 behind road 7 and cold water pipe 4, so that water be reheated.When distalmost end is used
When cold water is used alone in water spot 6, pressure switch 9 detects that distalmost end has been opened with the cooling water inlet of water spot 6 and will test knot
Fruit feeds back to controller, and controller closes circulation waterway 7 according to the signal control solenoid valve 8 fed back, so that hot-water line 5
The water of the inside cannot flow to cold water pipe 4 through circulation waterway 8, so will not occur hot water from hot-water line 5 flow to cold water pipe 4 and through with
The mixed regimen condition that water spot 6 flows out, and it can avoid the unnecessary waste consumption of combustion gas, solve industry pain spot.
Further, the cold valves connecting with cold water pipe 4 are provided with water spot 6, structure is simple, compact.
Preferably, the open and-shut mode of the open and-shut mode Yu solenoid valve 8 of cold valves has inverse relationship, and design is rationally, ingeniously
It is wonderful.
Specifically, the intersection of circulation waterway 7 and cold water pipe 4 and the cold water of distalmost end water spot 6 is arranged in pressure switch 9
Between valve, this further improves the reliabilities of pressure switch detection.
Particularly, pressure switch 9 is high-voltage switch gear, and design rationally, can further improve the accurate of pressure switch detection
Property.
In the present embodiment, in distalmost end with being provided with the cold valves connecting with cold water pipe 4, pressure switch 9 on water spot 6
By detecting the open and-shut modes of cold valves with for judging whether distalmost end is opened with the cooling water inlet of water spot 6, pressure switch 9
Distalmost end can be more accurately detected by using high-voltage switch gear whether to be opened with the cooling water inlet of water spot 6, but is not limited to high pressure
Switch, or low tension switch can also select other more particularly suitable pressure switches according to actual needs certainly.This implementation
In example, the open and-shut mode of cold valves and the open and-shut mode of solenoid valve 8 have inverse relationship, i.e., when pressure switch 9 detects cold water
When valve is in an open state, then it is judged as low pressure and closes solenoid valve 8；When pressure switch 9 detects that cold valves are in off state,
Then it is judged as high pressure and opens solenoid valve 8.
As shown in figure 3, water heater is in the initial state, distalmost end is in close state with the Cold water tap of water spot 6, pressure
Switch 9 detects as high pressure, opens simultaneously solenoid valve 9, and the hot water of 5 the inside of hot-water line can be through under the action of circulating pump 11 at this time
Circulation waterway 7, cold water pipe 4 and water inlet pipe 2, which re-enter into inside water heater 1, to be heated.When user individually opens cold valves
When using cold water, pressure switch 9 detects distalmost end and has been opened with the cooling water inlet of water spot 6, i.e., pressure switch 9 detects to be low
Pressure, the signal that controller is fed back according to pressure switch 9 at this time close solenoid valve 8, so that the water of 5 the inside of hot-water line is not
Cold water pipe 4 can be flowed to through circulation waterway 7, so will not occur hot water from hot-water line 5 flow to cold water pipe 4 and through with water spot 6 flow out
Mixed regimen condition.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
