Description
Technical field
The present invention relates to gas heater technical field, more particularly to a kind of gas heater central hot water circulation system.
Background technology
The hot water circulating device of prior art when installing without water return pipeline, more installed in the water inlet end of water heater, in heat
Water pipe installs a check valve with the distalmost end of cold water pipe, and hot-water line and cold water are coupled together to form a loop, and work is former
Reason there are about following two：
1) user presses pre- hot key, and the water pump in EGR is started working.Water heater detects water-flow signal and starts combustion
Burn, EGR detects water pump when water temperature reaches the preheating temperature of user's setting and quits work, and this preheating is completed, and is now opened
Hot water tap is carved with hot water stream and is gone out.
2) user voluntarily sets the preheating time long t of hot water circulating device according to length of pipe and situation, opens in user
When opening EGR preheating function, water pump is started working in hot water circulating device, the t of working time a length of setting, operating time t
Later, water pump quits work, and this preheating is completed, and now opens hot water tap and be carved with hot water stream.
At present the hot water circulating device of technology has following defect：
1) because hot water circulating device is arranged on the water inlet end of water heater, during using temperature decision condition, EGR is worked as
Temperature also not up to the preheating temperature value of setting when, the temperature at water outlet of water heater end considerably beyond pre- heat setting temperature,
Cause temperature overtemperature in hot-water line serious, and without mixed water, user's bathing after the completion of preheating can not be realized under return pipe state
There is the danger scalded.
2) it is hot water in cold water pipe after the completion of preheating, not only wastes gas, electricity, and with cold water meeting after field has been preheated
There is one section of hot water to flow out, affect user to use cold water.
3) the preheating time length required for different user difference pipeline situation is different, in installation process user with after sale
Personnel need to debug repeatedly, and installation and debugging workload is big.
4) in installation process, EGR is arranged on water feeding of heater end, not only needs the pipe to distalmost end water spot
Road carries out improvement and installation check valve, but also water feeding of heater end water route is transformed, and workload is larger.
The content of the invention
For problems of the prior art, it is an object of the invention to provide a kind of mounting structure is simple, preheated
Cheng Houneng meets instant-heating and opens i.e. cold gas heater central hot water circulation system simultaneously.
To reach object above, the present invention is adopted the following technical scheme that.
A kind of gas heater central hot water circulation system, including：Gas heater, is connected to entering on gas heater
Cold water pipe, hot-water outlet pipe, some use water spots being connected on hot-water outlet pipe, and be connected to each water spot and enter between cold water pipe
Cold water arm；Characterized in that, connector hot water circuit between the hot-water outlet pipe and cold water arm at distalmost end water spot
Device；The hot water circulating device includes：Connecting line, the check valve being serially connected on connecting line, water circulating pump and temperature are passed
Sensor, and the controller being connected with water circulating pump and temperature sensor control；The water inlet end of connecting line connects with hot-water outlet pipe
Connect, the water side of connecting line is connected with cold water arm.
Used as with improvement, the controller is the master controller of gas heater.
Used as with improvement, the controller is to be arranged in hot water circulating device and the communication of gas heater master controller
Discrete controller.
As with improvement, preheating temperature is set by controller, in warm, by the temperature in hot water circulating device
Degree sensor real-time monitoring water temperature；When hot water circulating device detects water temperature more than the preheating temperature for setting, controller control
Water pump in EGR quits work.
As with improvement, preheating time section is set by controller, in preheating time section, when real-time water temperature is less than setting
During a certain return difference temperature of temperature, the water pump in hot water circulating device is started working, and gas heater detects water-flow signal and starts
Work and heat in the water in pipeline.
Used as with improvement, the span of the return difference temperature is 0-15 DEG C
The invention has the beneficial effects as follows：
The first, hot water circulating device is arranged on the distalmost end of hot-water outlet pipe and cold water arm, is solved installed in water inlet end
The problem of the temperature overshot of presence, it is ensured that it is cold water in hot water, cold water pipe that hot-water line is after the completion of subscription time section and preheating, full
Also meet while foot instant-heating and open i.e. cold.
2nd, due to being integrated with the devices such as temperature sensor, circulating pump in hot water circulating device, only user's distalmost end need to be transformed
Water spot pipeline is used, the workload that EGR is installed is reduced.
