For example, some prior art discloses a control method of a gas water heating system, the method comprising: starting a water pump assembly, and obtaining the frequency of a water quantity servo control switch valve; calculating a water flow average value according to the frequency of the control switch valve of the water flow server; matching the calculated average value of the water flow with a pre-stored actual measurement database in the main controller, identifying the length of the hot water pipeline, calculating the water capacity of the hot water pipeline, and calculating the optimal cyclic heating time according to the water capacity; the main controller performs cyclic heating according to the optimal cyclic heating time. The method realizes quantitative and cyclic heating of the gas hot water system, avoids hot water in the hot water pipeline from flowing into the cold water pipeline, further reduces the influence of the circulating system on the water purifier in the cold water pipeline, and greatly reduces the consumption of gas.
For another example, a control method for intelligent preheating of a zero cold water gas water heater is disclosed in the prior art, the gas water heater comprises a water heater body, a tap water pipeline and a hot water pipeline, a circulation loop is formed among the water heater body, the tap water pipeline and the hot water pipeline, and the control method comprises the following steps: 1, judging whether the water inlet temperature of the gas water heater is smaller than a preset temperature; 2, controlling the gas water heater to start a preheating function for the first time; 3, judging whether the outlet water temperature of the gas water heater reaches a target temperature; 4, judging whether the circulation loop circulates for one circle or not; 5, obtaining the total preheating water quantity of one circle of circulation loop circulation; and 6, judging whether the water quantity flowing through the water heater body reaches the preset proportion of the total water quantity or not when the gas water heater starts the preheating function again.

Detailed Description
In order to make the technical problems solved by the present utility model, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.
As shown in fig. 1 and 2, the present embodiment provides a zero-cooling water system of a gas water heater, which comprises a gas water heater 1, a water inlet pipe 2, a water outlet pipe 3 and a water return pipe 5. The water inlet and the water outlet of the gas water heater 1 are respectively connected with a water inlet pipe 2 and a water outlet pipe 3, the water inlet pipe 2 is connected with a tap water pipe 4, and the tap water pipe 4 is also respectively connected to each cold water use port; the water outlet pipe 3 extends and covers all hot water use ports, and the furthest end of the water outlet pipe 3 is connected with the water return pipe 5 to the water inlet pipe 2. In addition, the gas water heater is internally provided with a heat exchanger 11, a circulating water pump 12, a water flow sensor 13, a water inlet temperature sensor 14, a water outlet temperature sensor 15 and a controller 16, wherein the water flow sensor 13, the circulating water pump 12 and the water inlet temperature sensor 14 are sequentially arranged on the water inlet side of the heat exchanger 11, and the water outlet temperature sensor 15 is arranged on the water outlet side of the heat exchanger 11. The water return pipe 5 is connected to one end of the water inlet pipe 2 close to the water inlet of the gas water heater, so that the influence of tap water is reduced. One end of the return pipe 5 connected with the water inlet pipe 2 is provided with a one-way valve 6 so as to prevent tap water from flowing into the return pipe. The circulating water pump 12 and the water flow sensor 13 are arranged on one side of the water inlet of the gas water heater, so that the service life is prevented from being influenced by the too high water temperature. An auxiliary heating device 17 is arranged on one side of the heat exchanger 11 close to the water inlet of the gas water heater, so that the stability of heating water is ensured. The conventional working principle of the zero cooling water system is as follows: the circulating water pump is used for enabling water to circulate between the circulating pipeline formed by the water outlet pipe and the water return pipe and the gas water heater, and meanwhile, the heat exchanger gradually heats the water in the circulating pipeline until the temperature value measured by the water inlet temperature sensor reaches the temperature preset by a user, so that the water temperature in the circulating pipeline is ensured to meet the requirement of the user, and the user can directly obtain hot water with the required temperature when the hot water faucet or the shower head is opened.
In the practical situation, the hot water in the water return pipe is not directly supplied to a user, so that the water temperature in the water outlet pipe can be ensured to meet the user requirement for saving energy. Therefore, the controller is internally provided with:
the water flow monitoring module is used for receiving the data of the water flow sensor and accumulating water flow;
the temperature monitoring module is used for receiving the data of the temperature sensor;
And the control module is used for controlling the heat exchanger and the circulating water pump to stop according to the data and the preset value of the water flow monitoring module and the temperature monitoring module.
For example, when the data of the temperature monitoring module reaches a preset value, namely the water outlet temperature of the gas water heater reaches the user requirement, the water flow monitoring module can be used for controlling the hot water with required flow to enter the water outlet pipe, so that excessive hot water is prevented from entering the water return pipe, and energy is saved.
Specifically, the control module includes:
The control triggering unit is used for enabling the water flow monitoring module to start accumulating water flow according to the data of the temperature monitoring module and a temperature preset value;
And the control completion unit is used for controlling the heat exchanger and the circulating water pump to stop according to the data of the water flow monitoring module and the flow preset value.
For example, knowing the volume of the water outlet pipe, only when the monitoring data of the water outlet temperature sensor is equal to the preset temperature value, the water flow monitoring module starts accumulating water flow, and stops heating and water circulation when the accumulated water flow is equal to the volume of the water outlet pipe, at the moment, the part of water with the water temperature equal to the preset temperature value just flows to the tail end of the water outlet pipe, namely, the water temperature in the whole water outlet pipe meets the preset temperature requirement, thereby avoiding heating the water temperature in the water return pipe to the preset temperature value, and saving energy. Meanwhile, due to the existence of the water return pipe, warm water cannot flow into the tap water pipe when the water is heated again later, and normal use of cold water by a user is guaranteed.
The above example is given as a case of knowing the volume of the outlet pipe, if the volume of the outlet pipe is unknown, and the return pipe is installed based on a zero-water heater, the length and the inside diameter of the return pipe are always known, so that the volume of the outlet pipe can be obtained by measuring the volume of the whole circulation pipeline. For this purpose, the controller is also provided with:
The circulating pipeline volume acquisition module is used for acquiring an acquisition time range according to the data of the temperature monitoring module and a temperature preset value, and acquiring the circulating pipeline volume according to the accumulated water flow of the water flow monitoring module in the acquisition time range; the circulating pipeline comprises the water outlet pipe and a water return pipe. The water flow monitoring module is enabled to accumulate water flow only at the moment when the heat exchanger and the circulating water pump start to work normally under the condition that the circulating pipeline is cold water, and the water can be considered to circulate just for a week until the water temperature monitored by the water inlet temperature sensor changes, so that the accumulated water flow can be used as the volume of the circulating pipeline.
Specifically, the circulation pipeline volume acquisition module includes:
The water flow accumulation triggering unit is used for triggering the water flow monitoring module to accumulate water flow when the monitoring value of the water outlet temperature sensor reaches a first temperature preset value.
The water flow accumulation stopping unit is used for stopping the water flow accumulation of the water flow monitoring module when the monitoring value of the water inlet temperature sensor reaches a second temperature preset value; the second temperature preset value is generally lower than the first temperature preset value by 1 ℃, namely, part of water heated at the moment of starting triggering the accumulated water flow just flows to the water outlet temperature sensor when stopping the accumulated water flow, and the temperature of the part of water is reduced by 1 ℃ due to heat exchange with a pipeline.
And the circulating pipeline volume output unit is used for outputting the accumulated water flow of the water flow monitoring module into the circulating pipeline volume.
In addition, the circulation line volume acquisition module further includes:
The re-acquisition unit is used for resetting and restarting the data of the water flow accumulation triggering unit, the water flow accumulation stopping unit and the circulating pipeline volume output unit when the unexpected situation occurs; the unexpected situations include the switching of a hot water tap, the shutdown of a gas water heater, the flameout of the gas water heater, and the like, which all affect the accuracy of the result, so that the acquisition is needed again.
And because the proportion of the water outlet pipe in different user houses to the circulating pipeline is different, the control module is internally provided with:
The preheating proportion setting unit is used for presetting the preheating proportion of the volume of the circulating pipeline; the control module obtains the flow preset value based on the circulating pipeline volume and the preheating proportion.

It will be understood by those skilled in the art that the present utility model is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the utility model.
