It asks.
In the present embodiment, when carrying out scale removal, the running speed of above-mentioned water pump 60 is relative to the time at sine wave or square wave
Function can make the cleaning solution of circulation form impact in each pipe by the setting, guarantee in each pipe and gas heater
Dirt is adequately cleaned.
The above-mentioned gas heater of the present embodiment specifically uses following steps when carrying out scale removal:
(it can be in one of pipe, be also possible to while multiple pipes firstly, detect in each pipe in water flow sensor
It is interior) water flow when becoming smaller and being more than preset value, i.e. capable of emitting scale removal instruction, the scale removal component 10 of gas heater control at this time
First valve 2 is closed, and the ball valve 9c on the first pipeline 9a and the second pipeline 9b of the second valve 4 of opening and cleaning box 5, with
Afterwards control water pump 60 start, and by running speed relative to the time at sine wave or square wave function in the way of in cleaning box 5
Cleaning solution carry out extraction conveying, cleaning solution successively passes through water inlet pipe 20, outlet pipe 30, hot-water line 50 and return pipe 40, right
Dirt in each pipe is once cleared up, and is subsequently flowed into cleaning box 5, later again by water pump 60 to clear in cleaning box 5
Clean liquid circulation extracts, until the dirt in above-mentioned each pipe is cleaned out.In the present embodiment, the standard cleaned out be it is above-mentioned into
Water flow in water pipe 20, outlet pipe 30, hot-water line 50 and return pipe 40 reaches preset value.
Then, everywhere by the cleaning solution in cleaning box 5, and it is put into clear water, passes through above-mentioned 60 circulation conveying cleaning box 5 of water pump
In interior clear water to above-mentioned each pipe, realization cleaning is washed away to residual cleaning liquid, repeat releasing cleaning box 5 in clear water and
It is put into clear water into cleaning box 5, until stopping when the turbidity for washing away the clear water after above-mentioned each pipe in cleaning box 5 reaches preset value
It only clears up, is cleaned out in each pipe above-mentioned at this time.In the present embodiment, the detection of the turbidity of above-mentioned clear water can pass through setting
Turbidity transducer is realized.
The gas heater of the present embodiment can be realized removing automatically to gas heater by above-mentioned scale removal component 10
Dirt reduces resource consumption.
Embodiment three
The difference between the present embodiment and the second embodiment lies in that the connection type of the scale removal component 10 of the present embodiment is different, specifically
, as shown in figure 4, the return pipe 40 and hot-water line 50 of the gas heater of the present embodiment are disconnected, i.e. the present embodiment
Gas heater does not have the effect of zero cold water.In the present embodiment, the return pipe 40 of gas heater is connected to scale removal component 10
First pipe 1 one end, hot-water line 50 is connected to the other end of first pipe 1.Remaining structure and embodiment two are all the same.
The present embodiment is by above-mentioned setting, and in scale removal, the cleaning solution in cleaning box 5 can be extracted by water pump, and successively be passed through
After crossing return pipe 40, water inlet pipe 20, outlet pipe 30 and hot-water line 50, cleaning box 5 is flowed into.In the process, to above-mentioned each pipe
Interior dirt is cleared up.Subsequent cleanup step and embodiment two is all the same, and details are not described herein.
Obviously, the above embodiment of the present invention is just for the sake of clearly illustrating examples made by the present invention, and being not is pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
