Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Embodiment one
Referring to Fig. 1, the present invention provides a kind of cold water recovery-type hot-water heating system, it include water heater 10, water heater 10 includes
Cold water water inlet pipe 11, hot water outlet pipe 12 and controller 13, cold water recovery-type hot-water heating system further also include water storage device
20, the first control valve 30, the second control valve 40 and first sensor (not shown)；Water storage device 20 includes water tank 24, water
Case water inlet pipe 21, radiator drain 22, return pipe 23, electric heating module 25 and second sensor (not shown)；First control
Valve 30 processed is connect with hot water outlet pipe 12, radiator drain 22, one end of return pipe 23 and external hot water outlet 50, and control is external
Hot water source when hot water outlet 50 is discharged, the first control valve 30 are electrically connected with controller 13；First sensor is set to
One control valve 30 connects one end of hot water outlet pipe 12, implies that first sensor detecting is hot water outlet pipe 12 and the first control
The water temperature of 30 link position of valve, main purpose be to judge by the coolant-temperature gage of 10 hot water outlet pipe 12 of water heater, meanwhile, first passes
Sensor and controller 13, which are electrically connected, is transmitted to controller 13 for the water temperature data sensed；The other end and water of return pipe 23
The connection of 24 water inlet pipe of case when hot water outlet pipe 12 is connected by the first control valve 30 with return pipe 23, can go out hot water whereby
Cold-water reflux in water pipe 12 is into water tank 24；Water tank water inlet pipe 21 passes through the second control valve 40 and cold water water inlet pipe 11 and outside
Cold water source 60 connects, and the water by the second control valve 40 control outside cold water source 60 is to flow directly into water heater 10 or flow to water tank
20, the second control valve 40 is electrically connected with controller 13, and the switching of the second control valve 40 is controlled by controller 13；Second sensor
And electric heating module 25 and controller 13 are electrically connected, and second sensor is arranged in water tank 24, the temperature in water tank 24 is sensed,
And the water temperature data in water tank 24 is transmitted to controller 13, and when the temperature in water tank 24 is lower than preset temperature, controller 13
Control electric heating module 25 heats the water in water tank 24.
Especially it is noted that water tank 24 is disposed proximate to external hot water outlet 50, external hot water outlet in the present embodiment
50 be tap hot water outlet, can shorten the length of radiator drain 22 as far as possible whereby, reduce the water being detained in water pipe,
Water resource waste when hot water tap being avoided to open.
It is set in water tank 24 in addition, further comprising water level sensor (not shown) in water tank, level sensor
Device and controller 13 are electrically connected, and the height of water level data in water tank 24 are transmitted to controller 13, work as water level by water level sensor
When lower than preset value, controller 13 controls the second control valve 40 and connects outside cold water source 60 and water tank water inlet pipe 21 to supplement water
Water in case 24.
Further, third control valve 70, third control valve 70 and controller 13 can be set in 24 water outlet of water tank
It is electrically connected, third control valve 70 mainly controls opening or closing for the water outlet of water tank 24, when the first control valve 30 goes out hot water
Before water pipe 21 and external hot water outlet 50 are connected, controller 13 first controls third control valve 70 and closes the water outlet of water tank 24, by water tank
After water discharge in outlet pipe 22, then hot water outlet pipe 11 and external hot water outlet 50 connected, in the closing of third control valve 70
Water tank 24 discharge water to the first control valve 30 by the time layout that hot water outlet pipe 12 and external hot water outlet 50 connect be about 0.5~
2 seconds, depending on the length of radiator drain 22, if the length of radiator drain 22 is longer, time interval time can also prolong
Long setting, but must consider the linking of hot water supply.
Embodiment two
A kind of present invention is also provided in the present embodiment and also proposes a kind of cold water according to aforementioned cold water recovery-type hot-water heating system
Recovery method comprises the steps of, but the following steps do not have certain ordinal relation；(1) first sensor is that setting exists
One end that first control valve is connect with hot water outlet pipe constantly monitors the water temperature of hot water outlet pipe, when user opens external heat
When water out, the first control valve carries out the switching of selecting type according to the water temperature that first sensor is monitored, if in hot water outlet pipe
Water temperature is lower than the first preset temperature, then the first control valve connects radiator drain and external hot water outlet, makes the water in water tank
Flow to external hot water outlet, and connect hot water outlet pipe and return pipe, make in script hot water outlet pipe colder water and not yet by
The water for being heated to the first preset temperature flow to water tank by return pipe, at this time since hot water outlet pipe and return pipe connect, hot water
Hydraulic pressure ignition controller in device is struck sparks in the case where water flowing puts a burner, heats to the water for flowing through water heater, to
The water of outflow hot water outlet pipe is heated to the first preset temperature, or is higher than the first preset temperature, and the first control valve goes out hot water
Water pipe and external hot water outlet are connected；If hot water outlet pipe's water temperature is higher than the first preset temperature, the first control valve connects hot water
Outlet pipe and external hot water outlet, the as general normal use state of water heater, water tank is not connected to return pipe at this time, water
Case water outlet is in off state.
(2) in the case of the closing of external hot water outlet, water level sensor senses water level in water tank, if being lower than the first default water
Position, then open the second control valve, and external cold water is made to flow into water tank with the water in subsidiary water tank；When what is opened in external hot water outlet
In the case of, water level sensor sense water tank in water level, if be lower than the second preset water level, indicate water heater not yet by water temperature heating extremely
First preset temperature, therefore the first control valve will not switch over, therefore the second control valve need to be opened, so that external cold water is flowed into water tank
Water flow to external hot water outlet in the hot water outlet pipe via water tank, and (water temperature that flows out at this time may be lower, or close to outside
The temperature of cold water source).
(3) in order to keep user in the water temperature of the external hot water outlet Shi Nengyou sufficient temp of unlatching next time, therefore outside
In the case of portion's hot water outlet is closed, second sensor senses water temperature in water tank, if being lower than the second predicted temperature, opens electric heating
Water in mould water tank is heated, and when being heated to the second preset temperature, electric heating module closes and carries out keeping warm mode.
Further, water outlet of water tank is provided with third control valve, the first control valve by external hot water outlet and heat
Before water outlet pipe is connected, third control valve first closes water outlet of water tank, will be controlled again by first after the water emptying in radiator drain
Valve processed connects hot water outlet pipe and external hot water outlet.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
