Example one
The present embodiment proposes a control method for a gas water heater, wherein the gas water heater adopted in the present embodiment includes components such as a burner 100, a heat exchanger 200, an electric heating module 300, a control device 400, a water inlet pipe 601, a water outlet pipe 602, and a fan (not shown in the figure), as shown in fig. 1. The control device 400 includes a processor, a memory, and a control program stored in the memory and executable by the processor for the gas water heater.
The burner 100 can burn gas to heat water flowing in the heat exchanger 200, and the electric heating module 300 can assist in electric heating of water flowing therethrough using the principle of electric heating. The inlet pipe 601 is connected to a water supply pipe in the user's home to introduce cold water, and the outlet pipe 602 is connected to a water terminal (hot water tap) in the user's home to output hot water.
As shown in fig. 2, the gas water heater control method of the present embodiment includes:
detecting the water consumption state of each water consumption point;
and when the water consumption point is opened, determining a water consumption mode corresponding to the water consumption point of the opened water, and controlling heating according to the water consumption mode, wherein the water consumption mode comprises a first water consumption mode and a second water consumption mode according to the estimated water consumption.
The method is characterized in that a water consumption mode is preset for each water consumption point, the setting basis is that the mode of estimating the water consumption of the water consumption point at least comprises a first water consumption mode and a second water consumption mode, wherein the small water consumption and the large water consumption are relative, and the estimated water consumption of the default first water consumption mode is smaller than the estimated water consumption of the second water consumption mode.
If a user house has X water consumption points, X is an integer larger than 1, each water consumption point is provided with a sending module, a receiving module is arranged at the home terminal of the gas water heater, communication is carried out between each water consumption point and the receiving module, after the gas water heater is installed at the user house, the sending modules at different points are matched with the receiving module of the home terminal, and different water consumption modes are defined for each water consumption point.
The communication mode of the sending module and the receiving module can adopt, but is not limited to, schemes such as power line carrier, Lora, BLE, Zegbee, Wifi, 433, 485, and the like.
Three water consumption points are used for example, in household water, the water consumption points can comprise kitchen tap water consumption points, bathroom shower water consumption points and the like, and according to the conventional water consumption habit, the kitchen tap water consumption points can be generally classified into a first water consumption mode for washing fruits and vegetables, tableware and the like. Similarly, the water spot of the bathroom faucet can be classified into the first water usage mode for the purpose of washing, rinsing and the like. Most of the water using points of the shower head in the bathroom meet the bathing requirement, and the shower head can be classified into a second water using mode.
The first water usage pattern and the second water usage pattern are only a rough classification, and may be further divided into two or more.
The gas water heater in the embodiment comprises two heating modes of electric heating and gas heating, the water consumption requirements are different, and the adopted optimal heating modes are also different. For example, because the electric heating mode has the advantage of fast heating, but the power of the electric heating is limited, the electric heating mode is preferably adopted for the water demand with the estimated small water consumption, and when the electric heating can meet the water demand, the gas heating is not required to be started. The gas heating has the advantage of high heating capacity, and the gas heating mode is preferably adopted for estimating the water demand with larger water consumption.
That is, in the heating control step, if the current water consumption mode is the first water consumption mode, the electric heating module is controlled to be started for heating;
and if the current water consumption mode is the second water consumption mode, controlling to start the burner for heating.
The gas water heater control method of this embodiment through for each water consumption point estimate water consumption and set for the water consumption mode, when detecting to have the water consumption point and open the water, according to the water consumption mode control heating that this water consumption point corresponds, realizes according to the execution heating control of actual water demand pertinence, promotes user's use and experiences.
And when the water consumption points start water consumption at the same time, determining that the corresponding water consumption mode is the second water consumption mode. When a single water consumption point is opened, the control can be carried out according to the water consumption mode of the water consumption point, and when a plurality of water consumption points are opened simultaneously, the default is that the water consumption demand is large, and the water consumption mode is set to be a second water consumption mode with large water consumption. According to the scheme, the initial setting is carried out based on the use habits and the conventional experiences of the user, the more complex judgment logic is saved, and the execution efficiency is improved.
In order to prevent the situation that the water flow is small although the water flow is present due to untightening of the water consumption point or other reasons, and avoid heating by mistake, in this embodiment, it is preferable that before the heating is controlled, the method further comprises:
detecting the current water flow:
when the current water flow is larger than the first flow, executing the heating control step, otherwise, not executing the heating control step, namely, not heating;
the current water flow is the current water flow through the gas water heater.
Since the water usage patterns set for the water usage points are based on the experience of water usage in the foregoing steps, in actual use, water usage is performed according to the set water usage patterns, but it cannot be completely excluded that the water usage points are not used according to a conventional water usage manner. In order to improve the universality of the control method and meet the control requirements of various situations, the heating control step in the embodiment further comprises the step of adjusting the heating mode. That is, if the current water usage mode is the first water usage mode, the method further comprises the step of adjusting the heating mode:
and judging whether the current water flow is larger than the second flow, if so, starting the burner for heating, and otherwise, not starting the burner for heating.
The water flow reflects the water using state of the user, and if the current water flow is larger than the second flow, the current water using point is determined as a first water consumption mode with small water consumption demand, but the actual water consumption is larger, so that when the current water flow is larger than the second flow, the burner is started to heat, the actual water consumption of the user is met, the hot water making capacity is prevented from failing to meet the user demand, and the user using experience is improved.
Wherein the second flow rate is greater than the first flow rate.
In the step of controlling heating, if the current water usage mode is the second water usage mode, the method further comprises the step of adjusting the heating mode:
respectively detecting the water inlet temperature and the water outlet temperature of the electric heating module;
when the water inlet temperature of the electric heating module is greater than or equal to the first temperature value or the water outlet temperature of the electric heating module is greater than or equal to the second temperature value, the electric heating module is not started, otherwise, the electric heating module is started. The scheme can avoid the situation that the electric heating module 300 is frequently opened due to frequent water opening of a user, and can further save electric energy consumption.
When the water heater starts, two states have, one kind is that apart from the last start time interval shorter, and the temperature of depositing water in the water heater and in the pipeline is higher, and through judging the temperature of intaking or the temperature of leaving water of electric heating module 300 this moment, when two arbitrary satisfieds or are close the user demand, the temperature of depositing water in the explanation pipeline can satisfy the user demand, the condition of cold water or double-layered raw water can not appear. The subsequent heating water is heated by the burner 100.
Another is that the temperature of the water stored in the water heater and in the piping decreases when the time interval from the previous start of the water heater is longer. When the opening condition of the electric heating module 300 is satisfied, the electric heating module 300 needs to be opened for auxiliary heating. Meanwhile, when the on condition of the burner 100 is satisfied, the burner 100 is required to ignite for combustion, and main heating is performed.
When the water inlet temperature of the electric heating module is larger than or equal to the first temperature value, the water inlet temperature entering the electric heating module meets or is close to the requirement of a user, the electric heating module does not need to be started, the increase of electric energy consumption is avoided, and therefore the electric heating module is not started.
When the outlet water temperature of the electric heating module is greater than or equal to the first temperature value, the temperature of the hot water output from the electric heating module meets or is close to the requirement of a user, the electric heating module does not need to be started, the increase of electric energy consumption is avoided, and therefore the electric heating module is not started.
In the step of controlling heating, if the current water consumption mode is the second water consumption mode, before controlling starting of the burner, the method further comprises the step of judging whether the starting condition of the burner is met:
judge whether current discharge is greater than the second flow, if current discharge is greater than the second flow, then start the combustor heating, otherwise, do not start the combustor heating to guarantee the safety of gas heating, prevent because of the less problem that if start the combustor of discharge, lead to the aqueous gasification in the pipeline and influence system safety.
When the burner and the electric heating module are both in the starting state, the fact that the water outlet temperature of the current burner 100 is low is reflected, in order to quickly reach the set target heating temperature, whether the current water flow is larger than the third flow or not is continuously judged, and if the current water flow is larger than the third flow, the flow regulating module is controlled to reduce the water flow.
Specifically, when the outlet water temperature of the burner 100 is low and the outlet water temperature of the electric heating module 300 is also low, and if the water flow rate is high, the energy consumption requirement for heating the current water flow to the target heating temperature is high, which cannot be achieved in a short time, so the embodiment is implemented by reducing the water flow rate. The water flow is eliminated, and under the condition that energy consumption supply is not changed, the water flow temperature can be quickly increased to the target heating temperature, so that the waiting time of a user is reduced.
The water flow rate can be adjusted in various ways, and can be realized by using a water servo or a water valve with adjustable opening degree, which is described in this embodiment by taking a water servo as an example.
The water volume servo is also called as a water volume servo valve, and mainly comprises a valve body, a water flow rotor component, a sensor, a valve core component, a motor and the like (not shown in the figure), when water is used at a water consumption point, water flows through, the magnetic water flow rotor rotates, the sensor senses and transmits current to the control device 400, the control device 400 calculates rapidly according to a target heating temperature, and the motor is controlled to drag the valve core component to adjust the water volume of a water outlet. The water quantity servo valve is mainly used for matching with the adjustment of the fuel gas proportional valve to achieve the optimal combustion state, thereby achieving the purpose of constant temperature.
Basic operation logic of water volume servo:
1. the water flow rotor component is a magnetic component, and when water flows through the water flow rotor, the water flow rotor is impacted to rotate.
2. After the hall sensor outside the valve body senses the change of the magnetic field, a corresponding pulse current is generated and sent to the control device 400.
3. The motor corresponds to the valve core assembly inside, and the motor controls the opening and closing degree of the valve core assembly to control the size of water flow.
Based on the operation principle of water volume servo, the method for controlling the flow regulating module to reduce the water flow in the embodiment comprises the following steps:
acquiring a water servo step number L;
the number of water servo steps is adjusted to L- Δ L, where 0 & ltΔ L & lt L.
The control device 400 calculates a target water flow rate corresponding to the adjustment step number Δ L based on the current flow rate and the target heating temperature, and adjusts the water servo.
The method further comprises the step of obtaining the set target heating temperature, and determining a first temperature value and a second temperature value according to the target heating temperature.
The target heating temperature can be bath temperature set by a user, and when the user does not set the target heating temperature is a default set value of the system.
As a preferred embodiment, since the water outputted from the electric heating module 300 is supplied to the direct water supply point through the pipe, the temperature of the discharged water from the electric heating module 300 can reflect the target heating temperature.
In this embodiment: first temperature value = target heating temperature- Δ T1;
second temperature value = target heating temperature.
The Δ T1 is a suitable value matched according to the whole system, and the value range thereof can be [1,5 ].
