Description
Technical field
The present invention relates to a kind of wall hanging furnace systems, more particularly to a kind of zero cold water fuel wall hanging furnace system, belong to wall-hung boiler
Field.
Background technique
Since the burnt gas wall hanging furnace of family is typically mounted on living balcony, and bath water is in bathroom, from bathroom to kitchen
Fang Youyi sections of longer pipelines, generally have between 10-30 meters.Therefore, when user has a bath, the cold water having in pipeline must first be put
Can just there be hot water outflow out, and to release many cold water to come out hot water, prolonged wait is not said, wastes very
More water.Special weather turns cool when turn cold, and hot water does not come out for a long time.Therefore, it solves first put one before using hot water every time
Duan Lengshui becomes the generally existing use problem of burnt gas wall hanging furnace industry.
In the prior art, the inside of burnt gas wall hanging furnace is equipped with a small-sized water circulating pump, and user gets ahead before with hot water
Start water pump before to wall-hung boiler, water pump can be extracted into the cold water in the water pipe in user family wall-hung boiler and here be heated, so
It is transported to again in the water pipe in user family afterwards, after waiting the cold water in service pipes to be all heated into hot water, user is in bathroom or kitchen
Tap is opened in room, hot water flows out soon.But start to heating from water pump and complete to need the regular hour, and
And therefore some gas energies of consumption and electric power energy if starting circulatory function is not convenient enough, cause to want with hot water Shi Bufang
Just starting or error starting will reduce user experience and more consumption gas energies and electric power energy.
Summary of the invention
In order to solve problem above, the object of the present invention is to provide a kind of zero cold water fuel wall hanging furnace system, make hot-water line
The water temperature on road is identical as burnt gas wall hanging furnace set temperature, and the multiple Fuzzy switch hot water tap of user is again turned on heat for a period of time
Tap just has the hot water of constant temperature to flow out, comfort and convenient.
In order to achieve the goal above, the technical solution adopted by the present invention:
A kind of zero cold water fuel wall hanging furnace system, including burnt gas wall hanging furnace, cold water pipe, hot-water line, water circulating pump, heating
Pump, heating outlet pipe, heating return pipe, water flow sensor, leaving water temperature sensors and controller.
The cooling water inlet of the cooling water outlet end of the cold water pipe multiple Cold water taps corresponding to the user and water circulating pump connects
It connects；The hot water outlet of hot-water line one end multiple hot-water valve connections corresponding to the user, the other end and burnt gas wall hanging furnace connects
It connects, the end of the hot-water line connects the cold water pipe.
The water circulating pump and heating pump are installed in burnt gas wall hanging furnace, the heating outlet pipe and heating return pipe one
End is separately connected the heating water outlet of burnt gas wall hanging furnace and the heating water return outlet of heating pump, and the other end connects user heating area.
The water flow sensor is mounted on the cooling water inlet end of water circulating pump, and the leaving water temperature sensors are mounted on heat
In water pipe, the controller and the burnt gas wall hanging furnace, water circulating pump, heating pump, water flow sensor and leaving water temperature are sensed
Device is electrically connected.
When the kitchen or toilet of user are needed using hot water, hot-water valve is first opened, is then shut off hot-water valve,
In this period, the water flow sensor at water circulating pump cooling water inlet end has detected that cold water passes through, the information that cold water is passed through
It is sent to controller；The leaving water temperature sensors in hot-water line detect the temperature of water in hot-water line at the same time, by temperature information
It is sent to controller；If temperature is less than start-up temperature, the starting of controller control loop water pump, control burnt gas wall hanging furnace work is followed
Ring water pump extracts the cold water in cold water pipe and hot-water line, and the cold water in the hot-water line being connected to cold water pipe is extracted into wall-hung boiler and is added
Heat, hot-water line and cold water pipe form circuit, and hot-water line is not formed into a loop with tap water cold water pipe, therefore circulating pump will not extract
To the cold water of tap water cold water pipe.When leaving water temperature sensors detect that leaving water temperature is start-up temperature, controller control
Water circulating pump and wall-hung boiler stop working, and the temperature of water is starting water temperature in hot-water line at this time, when user further opens hot water valve,
Hot-water line just has the hot water of constant temperature to flow out.
Heating pump, heating outlet pipe and heating return pipe are used for wall-hung boiler heating, and wall-hung boiler heats water, and hot water is from heating
Water outlet enters heating outlet pipe, the heating zone of user is flowed through, for user heating；Heating is pumped the lower heat of temperature in heating zone
Water is drawn into wall-hung boiler from heating return pipe and reheats, and the heating zone of user is again fed to after heating, and so circulation adds
Hot water.
It further, the hot-water line and cold water pipe connecting pin are equipped with check valve, enter water can only from hot-water line
In cold water pipe, it is therefore prevented that the cold water in cold water pipe enters in hot-water line.
Further, the water flow sensor includes copper valve body, water flow rotor component, current stabilization component and Hall member
Part, the Hall element are connect with controller signals.When water flow passes through rotor assembly, the magnet rotor of water flow rotor component turns
It is dynamic, and revolving speed, with the linear variation of flow, Hall element exports corresponding pulse signal and feeds back to controller, by controller
Judge water flow size；When specifically used, user can switch hot-water valve twice in three seconds, prevent user misoperation from leading
Wall-hung boiler work is caused, controller significantlys change this feature according to water flow sensor pulse frequency twice, to reach control
Start the purpose of burnt gas wall hanging furnace.
Beneficial effects of the present invention: the cold water in the hot-water line being connected to cold water pipe is extracted by the present invention by water circulating pump
It is reheated in wall-hung boiler, when user being made to open hot-water valve, hot-water line just has the hot water of constant temperature to flow out, comfort and convenient；It avoids
User goes to starting single cycle function on fuel wall hanging furnace panel, and user any hot water tap can start circulation at home
Function saves combustion gas, electric power and water resource, and is not easy to malfunction；Structure is simple, in traditional energy-saving gas wall-hung boiler
On the basis of be only added to sensor and water circulating pump, reduce the cost of manufacture and use.
