Description
Technical field
The invention belongs to gas heater technical fields, and in particular to a kind of to shut down controlling party for gas heater
Method.
Background technique
In the case that zero cold water gas heater refers to not boiled water, zero cold water function is opened, at this time the water inside water heater
Pump will start, and after starting, hot water line's water flow is moved up, and is flowed out through water heater outlet, and the water flow of outflow passes through water return pipeline
Water heater is flowed back to again, forms circulation line, after water heater has detected water-flow signal, combustion heating is opened, after 3-5 minutes
The water of entire circulation line is all heated to setting temperature, when user's bathing, one, which blooms, which spills, hot water, will not first flow out cold
Water, i.e. " zero " cold water；In order to improve bathing experience, function of increasing pressure generally will increase, however, since user opens function of increasing pressure
Afterwards, water pump can start, and user turns off tap, and since water pump is in the open state at this time, water heater still be can be detected
Water flow, therefore can not judge whether user closes water.
Summary of the invention
Shut down control method for gas heater the object of the present invention is to provide a kind of, can intelligent recognition user whether
Guan Shui, and then gas heater is closed in time, avoid energy waste.
The technical scheme adopted by the invention is that:
A kind of to shut down control method for gas heater, the outlet pipeline of the gas heater passes through the first triple valve
Composition circulation line is connected with the water return pipeline of gas heater, the inlet pipeline of gas heater is connected to by the second triple valve
On the circulation line, one or more watering equipments are provided on the outlet pipeline and inlet pipeline；
Open at least any one watering equipment, the water pump of gas heater is opened, tap water by inlet pipeline to
Wetting system supplies water, and the hot water after gas heater heats is supplied water by outlet pipeline to watering equipment；If continuous acquisition in real time
The water flow data group of group inlet pipeline is done, the size relation between the water flow data group according to several groups determines water flow
Whether continue to decline；After determining that the water flow continues to decline, the current water flow of inlet pipeline is acquired, according to the current water
Relationship in water flow data group described in flow and several groups between first group of water flow data group determines whether watering equipment closes
It closes；After determining that watering equipment has been switched off, close the water pump of gas heater, according in outlet pipeline the case where water flow it is true
It is fixed whether to close gas heater.
The features of the present invention also characterized in that:
Several groups water flow data group described in several groups includes at least 10 groups, respectively A (1), A (2), A (3) ... A
(n), wherein n >=10, and A (1) is the water flow data group acquired for the first time.
Water flow data group described in every group includes at least ten water flow value, respectively a (1), a (2) a (3) ... a (m),
Wherein m >=10, and a (1) is the water flow value acquired for the first time.
Any one group of water flow data group includes upper one group of water flow number in several groups water flow data group described in several groups
The water flow value according to the 2nd later all water flow values in group and currently acquired.
The size relation between several groups water flow data group that the basis acquires in real time determines whether water flow continues
Decline, specifically: when sum (1) < sum (2) < sum (3) ... is when sum (n), determine that water flow continues to decline；Conversely, water flow
Amount does not continue to decline, and continues the water flow data group for acquiring inlet pipeline (3)；
Wherein, sum (1) is the sum of all water flow values in water flow data group A (1), and sum (2) is water flow data group A
(2) the sum of all water flow values ... sum (n) is the sum of all water flow values in water flow data group A (n) in.
Whether the relationship according between the current water flow and several groups water flow data group determines watering equipment
It closes, specifically:
As current water flow L < sum (1)/n-1, then water flow at least reduces 1L, determines that user has been switched off and is set with water
It is standby；Otherwise watering equipment is used.
It is described according to determine whether the case where water flow in outlet pipeline close gas heater, specifically:
When the water flow is less than flow threshold, gas heater is closed；When the water flow is more than or equal to flow threshold
When value, gas heater works on.
It is described when the water flow be more than or equal to flow threshold when, gas heater works on, later, further includes: when
When the temperature of the inlet pipeline acquired in real time is less than temperature threshold, water pump is reopened.
The temperature threshold is Ts-M, wherein Ts is that temperature, 2 < M < 5 are arranged in gas heater.
The water flow value acquires primary at interval of 20ms.
Compared with prior art, the present invention determines user Guan Shui by the situation of change of water flow in inlet pipeline, in turn
It switches off the pump, then according to closing gas heater is determined whether in outlet pipeline the case where water flow, realizes water heater
Intelligence shuts down control, and dual judgement, avoids maloperation bring inconvenient.
