Description
Technical field
The present invention relates to gas heater field more particularly to a kind of gas heater anti-blocking methods.
Background technique
Most of home pipe design is long and complicated at present, when using gas heater, needs to bleed off and is filled in pipe originally
Water heater could be gone out after cold water in road, not only waste water resource in this way, but also waste the equal hot water time.Occur on the market thus
Much built-in having circulation water heaters with water pump, the water in pipeline are preheated in advance, to guarantee hot water end water instant-heating.
The prior art is usually that will exchange water pump, and exchange water pump and there was only feeder ear, without feedback end, cannot be understood in real time
The revolving speed of water pump and the information of water pump electric current guarantee that water pump in safe operation, can only be sensed by the water flow in pipeline
Device to judge that whether water pump dallies or stall, can not really reflect the operating condition of water pump indirectly.
Summary of the invention
The technical problem to be solved by the present invention is to for the prior art status provide it is a kind of can directly detect water pump fortune
Row situation is to accurately identify the gas heater anti-blocking method of water pump stall or idle running and energy discharge part failure.
The technical scheme of the invention to solve the technical problem is: the gas heater anti-blocking method, including into
Waterpipe, the water inlet line are equipped with water pump, it is characterised in that:
The water pump is DC water pump；The water pump electric signal connects control circuit；The control circuit also electric signal connects
It is connected to warning device；
When control circuit detects the revolving speed of DC water pump lower than limit value, control circuit closes DC water pump, control
Water pump enters diagnosis and debugger；
The diagnosis and debugger are as follows:
Control circuit line traffic control water pump carries out first time period with the first revolving speed, and control circuit directly turns water pump later
Speed draws high to the second revolving speed and runs second time period, and then control circuit stops the operating of the water pump；
After being spaced the third period, routinely working voltage opens the water pump to control circuit, and the revolving speed for detecting water pump is
It is no to be lower than limit value；If pump rotary speed reaches normal operation revolving speed, control circuit jumps out diagnosis and debugger, into water
The normal operation program of pump；If the revolving speed of water pump is still below limit value, the diagnosis and debugger are repeated；
Repeat the diagnosis and debugger at least twice；
If diagnosing revolving speed of the water pump detected with debugger in normal operating voltage three times is below limit
Definite value, control circuit switch off the pump, and issue standby signal by warning device.
It is preferred that the diagnosis and debugger are in triplicate；
The first time period is 8~15 seconds, and the second time period is 3~5 seconds；The third period be 50~
100 seconds.
Preferably, first revolving speed is the revolving speed under low setting voltage, and second revolving speed is to set voltage in height
Under revolving speed.
The low setting voltage is preferably 5~10V, and the height sets voltage as lower than 5~10V of the water pump voltage rating
Voltage.
Compared with prior art, gas heater anti-blocking method provided by the present invention uses DC water pump, utilizes direct current
The feedback end of water pump can understand the revolving speed of water pump and the information of water pump electric current in real time, and pass through specifically diagnosis and troubleshooting
Step can be automatically drained out small plugging fault, and water pump is made to enter normal operation program；For the plugging fault that can not be discharged,
Warning message is prompted, to guarantee that water pump is being safely operated；Method provided by the present invention can accurately identify the stall of water pump
Or idle running, the failure rate of water pump is greatly reduced, the experience of user is improved.
Detailed description of the invention
Fig. 1 is the schematic diagram of the embodiment of the present invention；
Fig. 2 is control flow chart of the embodiment of the present invention
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As depicted in figs. 1 and 2, which is equipped with DC water pump 2 on water inlet line 1；2 electric signal of DC water pump
Control circuit (not shown) is connected, control circuit electric signal connects warning device.
Warning device can be text prompt, be also possible to sound-light alarm.In the prior art can be selected as needed
It anticipates one kind.
In the present embodiment, the working voltage of DC water pump is 0~40V, normal working voltage 30V, it is low set voltage as
10V, height set voltage as 35V；First time period is 10 seconds, and second time period is 3 seconds, and the third period is 60 seconds.
The specific method is as follows:
When pump working, when control circuit detects the revolving speed of DC water pump lower than limit value, control circuit closes water
Pump, control water pump enter diagnosis and debugger；
The specific method is as follows with debugger for diagnosis:
Control circuit line traffic control water pump carries out first time period with the first revolving speed, i.e. water pump is run 10 seconds under 10V voltage
Afterwards, control circuit is directly by voltage increase to 35V, and controls water pump at 35V and run second time period with the second revolving speed, i.e., and 4
Second, then control circuit stops water pump.
It by the low-speed running of water pump and runs at high speed, plays the role of unimpeded to water pump and pipeline, some small blockings are former
Barrier can be flushed away under the high velocity effect after low speed with water flow.
It is spaced the third period, i.e., after 1 minute, routinely working voltage opens water pump to control circuit at 30V, detects
Whether the revolving speed of water pump is lower than limit value；If pump rotary speed reaches rated speed range, diagnosis and debugger are jumped out, into
Enter normal water pump operation program；If pump rotary speed is still below limit value, records stall number and add 1；And divide in stopping 1
Zhong Hou, control circuit control water pump are again introduced into diagnosis and debugger.
After starting water pump under normal voltage again, if the revolving speed of water pump is still below limit value, after stopping 1 minute
It is again introduced into diagnosis and debugger.
Diagnosis, if the revolving speed of water pump is still below limit value, judges water pump or pipeline quilt with after debugger three times
It is stifled, at this point, control circuit switches off the pump, and issues and issue standby signal by warning device, user's fault of water pump is reminded, manually
Intervention.
