The control method of above-mentioned water heater anti-freezing structure, including:
Step 1, input target water temperature by the inputting interface of control module to control chip；
Step 2, control chip are by the water temperature in cooling-water temperature sensor monitoring inlet pipeline, outlet pipeline；
Step 3, when cooling-water temperature sensor monitoring inlet pipeline or outlet pipeline in water temperature less than target water temperature time, control mould
Block starts circulating device and drives the water in inlet pipeline and outlet pipeline to form circulation and at water pipeline, water heater and outlet pipe
Road circulates；
Step 4, when cooling-water temperature sensor monitoring inlet pipeline, outlet pipeline in water temperature higher than target water temperature time, control mould
Block closes circulating device.
The control method of described water heater anti-freezing structure, step 1 also includes step 1.2, by the input of control module
Interface is to control chip input heating water temperature；Correspondingly, step 3 also includes step 3.2, when cooling-water temperature sensor monitoring circulating device
When water side water temperature is less than heating water temperature, control module starts heating module and heats current, until cooling-water temperature sensor is surveyed
Obtaining circulating device water side temperature higher than heating water temperature, now control module closes heating module.
The control method of described water heater anti-freezing structure, the preset minimum discharge of control chip in control module,
When flow transducer records discharge less than preset value, control module starts circulating device and heating module.
The another kind of control method of above-mentioned water heater anti-freezing structure,
Step 1, by the inputting interface of control module to control chip input interval time and circulation time；
Step 2, control chip are clocked into state, and now flow transducer records current is halted state；
Step 3, when interval circulation time reach described in step 1 be spaced circulation time, control module start circulating device, follow
Loop device drives the water in inlet pipeline and outlet pipeline form circulation and circulate in water pipeline, water heater and outlet pipeline
Flowing；Now control chip according to step 1 preset circulation time and enter countdown state, when the time make zero, control module
Closing circulating device, now flow transducer records current is halted state.
The control method of any of the above water heater anti-freezing structure, to the control chip of control module preset correction discharge number
Value, when cooling-water temperature sensor records water temperature less than preset value, control module starts circulating device with default correction discharge for mark
Quasi-drive current circulate 1 ~ 2 minute, so that current are sufficiently mixed everywhere in inlet pipeline, water heater and outlet pipeline；
Now control chip by the data again gathered in cooling-water temperature sensor and judges whether to need to start circulating device.
The mentality of designing of this water heater anti-freezing structure and control method thereof is to increase current to follow in the inside of existing water heater
Loop systems, so that water heater place hot water line forms a loop.Principle of the present utility model is when temperature in blood circulation
When in detector perception water pipe, water temperature is less than controller design temperature, controller is by drive system internal circulation pump driving means, real
In existing whole water pipe circuit, current are transformed into flow regime by resting state, water temperature in water pipe is monitored in real time water temperature change thus
Realizing each stage running of automatic decision, in reaching anti-antipriming pipe, water body freezes and destroys water pipe.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that existing gas heater combines anti-freezing structure described in the utility model.
Detailed description of the invention
This utility model is further illustrated below by way of specific embodiment.
As it is shown in figure 1, a kind of water heater anti-freezing structure, it include with inlet pipeline 1, heating module, with controlling core
Sheet and the control module of inputting interface, outlet pipeline 2 and by above-mentioned pipeline and module collection in the casing of one；Also include following
Loop device 3, the water side of described circulating device 3 and water inlet end are connected with inlet pipeline 1 and outlet pipeline 2 and both are connected respectively
Logical, when control module starts circulating device 3, the water in inlet pipeline 1 flows successively through heating module, outlet pipeline 2, circulating device 3
Rear return inlet pipeline 1.
Described water heater anti-freezing structure, control module also includes multiple cooling-water temperature sensor 4 and multiple flow transducer 5,
Described cooling-water temperature sensor 4, flow transducer 5 are respectively arranged in inlet pipeline 1, the water side of circulating device 3 and outlet pipeline 2
In.
Described water heater anti-freezing structure, is in series with a check valve between water side and the inlet pipeline 1 of circulating device 3
6, the water of inlet pipeline 1 cannot be refluxed to circulating device 3 by the cut-off of check valve.
Above-mentioned water heater anti-freezing structure, circulating device 3 includes a circulating pump.
In above-mentioned water heater anti-freezing structure, heating module is referred to the fire row structure heated by current by combustion gas or leads to
The electric heating device crossing the electric energy after electric energy or solar energy conversion thus heated by current.
The using method of above-mentioned water heater anti-freezing structure:
When in cooling-water temperature sensor records water pipe, coolant-temperature gage is less than 5 DEG C, water heater internal control module starts circulating pump, with
Controlling 1.5L/min is target flow operating, and in making outlet pipeline, water is transformed into flow rate regime by resting state, due to whole water
Temperature difference is there is in pipeline；After circulating pump starts operating a period of time, in cooling-water temperature sensor detects water pipe, temperature is more than 5 DEG C
Time, circulating pump keeps 1.5L/min to remain in operation after 1min stopping.Above action ensures when ambient temperature is critical close to zero degree
Water heater place water pipe circuit unlikely icing during point.
When in cooling-water temperature sensor detects pipeline, water temperature is less than 2 DEG C, water heater internal control module starts circulating pump with control
8L/min processed is that target flow starts running, and flow transducer starts water heater and starts burning work (burning startup target this moment
Flow >=2.5L/min), water in whole outlet pipeline is carried out heat cycles.Water in cooling-water temperature sensor detects whole pipeline
When temperature is more than 4 DEG C, circulating pump shuts down, and water heater burning this moment is closed Posterior circle pump and operated with 1.5L/min target flow
Stop after 30min.
When all not reaching both the above temperature range such as outlet pipeline temperature, in water heater, control module starts circulating pump,
After the 3h of interval, automatically operate 1min with 1.5L/min for target flow, after in making outlet pipe, each section of pipeline water temperature is sufficiently mixed
Feedback actual water temperature, causes temperature sensor immediately monitoring current water temperature in system.
Above control method, can combine according to actual demand or single use different and change according to ambient temperature
Preset water temperature and flow.
