Example 2
The present embodiment provides a control method of a water heater, which is implemented by using the water heater of embodiment 1 with reference to fig. 2, and the control method is applied to a controller of the water heater, and the control method includes:
s1, when the working mode of the water heater is a re-water-outlet constant-temperature mode, water flow collected by a flow sensor is obtained.
And S2, when the water flow is reduced to a first preset threshold value, controlling the first electromagnetic valve and the second electromagnetic valve to be in an opening state, and controlling the third electromagnetic valve to be in a closing state.
The first preset threshold may be set according to the requirement, for example, the first preset threshold is set to 2L/min (liter/minute).
In the initial state of the water heater, no water is stored in the expansion water tank, the first electromagnetic valve is in an open state, and the second electromagnetic valve and the third electromagnetic valve are in a closed state. When a user opens the hot water faucet, tap water flows into the water heater from the water inlet branch, flows through the heat exchange branch and then flows out from the water outlet branch. When the user closes the hot water tap, the water heater still maintains the constant temperature burning state.
Referring to fig. 3, when the water flow rate decreases to the first preset threshold, the tap water will pass through the combustion heat exchange system, and then flow into the expansion tank 42 through the communication pipe, and the expansion tank 42 enters the process of storing hot water. The direction of the arrows indicates the direction of water flow.
And S3, when the water flow rises to a first preset threshold and the continuous duration that the water flow is smaller than the first preset threshold is smaller than a preset duration, controlling the first electromagnetic valve and the second electromagnetic valve to be in a closed state, and controlling the third electromagnetic valve to be in an open state.
The preset time period is set according to actual requirements, for example 3 minutes.
Referring to fig. 4, when the user turns on the hot water faucet again within 3 minutes, the water flow rate rises to the first preset threshold again, and it is determined that the user is in a re-outflow water demand state. At this time, the water pressure at the outlet of the water heater will become low, and since the first solenoid valve 44 and the second solenoid valve 41 are in the closed state, the third solenoid valve 43 is controlled to be in the open state, at this time, the water in the expansion water tank 42 will flow out from the passage of the third solenoid valve 43 under the air pressure of the expansion water tank 42, then flow through the water quantity sensor and the heat exchange branch (combustion heat exchange system), and finally flow out from the water outlet joint. The direction of the arrow indicates the direction of the water flow.
In the embodiment, because the water in the expansion water tank is the hot water stored in the previous hot water storage process, the cold water section is not available in the processes of cleaning and igniting the fan of the water heater when the water is discharged again, so that the temperature drop phenomenon of the discharged water is avoided, and the experience of using the water heater by a user is improved.
In an alternative embodiment, referring to fig. 5, the control method further comprises:
and S4, when the water flow is reduced to a second preset threshold value, controlling the first electromagnetic valve and the second electromagnetic valve to be in a closed state, and controlling the third electromagnetic valve to be in an open state.
And the second preset threshold value is smaller than the first preset threshold value. For example, when the first preset threshold is 2L/min, the second preset threshold may be set to 1L/min.
In the embodiment, when the water flow rate decreases to the second preset threshold, it is determined that the expansion water tank is full of hot water, so that the first electromagnetic valve and the second electromagnetic valve are maintained in the closed state, and the third electromagnetic valve is controlled to be in the open state, so as to wait for the user to open the faucet of the water heater again.
In an alternative embodiment, referring to fig. 6, the control method further includes:
when the first and second solenoid valves are in the closed state and the third solenoid valve is in the open state, S5 is executed.
And S5, if the water flow is reduced to a third preset threshold value, controlling the first electromagnetic valve to be in an open state, and controlling the second electromagnetic valve and the third electromagnetic valve to be in a closed state.
The third preset threshold is set according to actual requirements, and for example, the third preset threshold may be set to be 2.5L/min.
In this embodiment, referring to fig. 7, the arrow direction represents the advancing direction of the water flow, and when the flow sensor 2 detects that the flow rate of the hot water provided by the expansion water tank 42 is reduced to the third preset threshold, it is determined that the hot water stored in the expansion water tank 42 is completely consumed, and at this time, the first electromagnetic valve 44 is controlled to be in an open state, and the second electromagnetic valve 41 and the third electromagnetic valve 43 are controlled to be in a closed state, so that the water heater enters a normal constant temperature heating process.
In an alternative embodiment, referring to fig. 6, the control method further includes:
s6, when the continuous duration of the water flow smaller than the first preset threshold is larger than or equal to the preset duration, controlling the first electromagnetic valve to be in an open state, and controlling the second electromagnetic valve and the third electromagnetic valve to be in a closed state.
The preset time period is set according to actual requirements, for example 3 minutes.
In the embodiment, if the user does not open the hot water tap again within the preset time, the water heater exits from the water outlet waiting state again, the heating process is reduced, and the waste of fuel gas is avoided.
In an optional embodiment, the control method further comprises:
and S7, when the working mode of the water heater is a voltage stabilization mode, controlling the first electromagnetic valve and the third electromagnetic valve to be in an opening state, and controlling the second electromagnetic valve to be in a closing state.
In the present embodiment, if the water pressure in the home of the user greatly fluctuates, the outlet water temperature of the water heater becomes unstable. The water heater can also set a voltage stabilizing mode. Under the voltage stabilization mode, the controller controls the first electromagnetic valve and the third electromagnetic valve to be in an opening state, and controls the second electromagnetic valve to be in a closing state. Like this with the hot water in-process, expansion tank just can absorb discharge when the high pressure, release discharge during the low pressure reaches the function of stabilizing the discharge, improves the user and uses the experience of water heater.
An example of a control method using a water heater is provided below.
Suppose that the first preset threshold is 2L/min, the second preset threshold is 1L/min, the third preset threshold is 2.5L/min, and the preset time is 3 minutes.
In an initial state, no water is stored in the expansion tank, the first electromagnetic valve is in an open state, and the second electromagnetic valve and the third electromagnetic valve are in a closed state. When a user opens the hot water faucet, tap water flows into the water heater from the water inlet joint (namely, the water inlet of the water inlet branch), flows through the combustion heat exchange system (namely, the heat exchange branch) and then flows out from the water outlet joint (namely, the water outlet of the water outlet branch). The state of the water heater is the same as that of a common water heater.
Then the user closes the hot water tap, and the water heater still maintains the constant temperature burning state, and when detecting that discharge is less than 2L/min, the controller opens the second solenoid valve. Because the expansion water tank does not store water, tap water flows into the expansion water tank through the combustion heat exchange system and then the communicating pipe at the moment, and the expansion water tank enters the heat storage process.
When the flow is less than 1L/min, the expansion water tank is judged to be full of hot water, the combustion of the water heater is stopped, the controller closes the first electromagnetic valve, closes the second electromagnetic valve and opens the third electromagnetic valve. This state is maintained, waiting for the user to turn on the hot water tap again.
When a user opens the hot water faucet again within 3 minutes, the water pressure at the water outlet of the water heater becomes low, the first electromagnetic valve and the second electromagnetic valve are closed, the third electromagnetic valve is opened, and at this time, water in the expansion water tank flows out from a channel of the third electromagnetic valve under the action of the air pressure of the expansion water tank, then flows through the water quantity sensor (namely the flow sensor) and the combustion heat exchange system, and finally flows out from the water outlet connector, and at this time, the water heater judges that the user is in a water re-outlet demand state. Because the water in the expansion water tank is the hot water stored in the previous heat storage process, the cold water section is not available in the processes of cleaning the fan and igniting the water heater when the water is discharged again, and the temperature drop phenomenon of the discharged water is avoided.
And when the water quantity sensor detects that the flow of the hot water provided by the expansion water tank is less than 2.5L/min, judging that the hot water stored in the expansion water tank is completely consumed. At this time, the first solenoid valve is opened, and the third solenoid valve is closed, and at this time, the second solenoid valve is kept in the original closed state. Thus, the water heater enters a normal constant temperature heating process.
If the user does not open the hot water faucet again within 3 minutes, the water heater exits the water re-outlet waiting state, and the controller opens the first electromagnetic valve, closes the second electromagnetic valve and closes the third electromagnetic valve.
In addition, if the water pressure in the house of the user greatly fluctuates, so that the outlet water temperature is extremely unstable, a pressure stabilizing mode can be set at the time. When the user switches to the voltage stabilization mode, the controller maintains the states of opening the first electromagnetic valve, closing the second electromagnetic valve and opening the third electromagnetic valve. Therefore, in the process of using hot water, the expansion water tank can absorb water flow at high pressure and release water flow at low pressure, so as to achieve the function of stabilizing the water outlet flow.
The expansion water tank is matched with the opening and closing logic of the valve, so that the heat storage process when a user closes water is formed, the hot water is output in time when water is discharged again, and the repeated heat storage process can be reliably carried out. In addition, on the premise of not changing the structure, the switching use of two functions of the constant temperature and the pressure stabilizing mode of the effluent can be realized.
