[0064] The present disclosure is further illustrated below by way of embodiments, but the present disclosure is not limited to the scope of the embodiments described herein.

[0065] This disclosure relates to a gas water heater (hereinafter referred to as the water heater), see [link to relevant documentation]. Figure 1 This is a schematic diagram of a water heater provided as an exemplary embodiment of the present disclosure. The water heater includes a fan 01, a heat exchanger 02, a temperature relay 03, an ignition needle 04, an igniter 05, a b group of burners 06, an a group of burners 07, a b group of sectional valves 08, an a group of sectional valves 09, a proportional valve 10, a water flow sensor 11, a main valve 12, an outlet water temperature sensor 13, an inlet water temperature sensor 14, a power supply board 15, and a display board 16. The following embodiments are all implemented with respect to this water heater.

[0066] Example 1

[0067] Figure 2 A flowchart illustrating an exemplary embodiment of this disclosure provides a control method for a water heater, the water heater including a water flow sensor and a heat exchanger, the control method including:

[0068] Step 101: Obtain the water flow rate of the water heater.

[0069] In this step, the water flow sensor acquires the data, and this sensor is typically located near the inlet of the water inlet pipe. The position of the water flow sensor in the inlet pipe can be adjusted as needed. In this disclosure, the water flow rate is used to calculate the travel time required for the water flow sensor to reach the heat exchanger. Furthermore, it should be understood that one purpose of the water flow sensor's monitoring of water flow is to determine when to trigger the water heater to start operating. Starting the water heater means the heat exchanger begins working, i.e., heating the water flowing through it. When the water flow rate exceeds a threshold, it is determined that the user needs hot water, and therefore the heat exchanger needs to be controlled to start operating at an appropriate time. Simultaneously, the operation of the heat exchanger requires the cooperation of other components, including but not limited to proportional valves and fans. For example, the fan needs to provide sufficient speed to provide enough air for gas combustion and / or provide wind resistance.

[0070] Step 102: Determine the travel time required for water to travel from the water flow sensor to the heat exchanger based on the water flow rate. The water heater includes the inlet pipe.

[0071] Optionally, see Figure 3 Step 102 specifically includes the following steps:

[0072] Step 1021: Determine the pipe volume corresponding to the pipe distance in the inlet pipe based on the inner diameter of the inlet pipe and the pipe distance from the water flow sensor to the heat exchanger.

[0073] In one specific embodiment, the pipe volume can be calculated using the following formula:

[0074] πr 2 S;

[0075] Where r is the inner diameter of the inlet pipe, and S is the pipe distance from the water flow sensor to the heat exchanger.

[0076] Step 1022: Determine the arrival time based on the water flow rate and pipeline volume.

[0077] In one specific embodiment, the arrival time can be calculated using the following formula:

[0078] T=(πr 2 S) / F;

[0079] Where T is the arrival time, r is the inner diameter of the inlet pipe, S is the pipe distance from the water flow sensor to the heat exchanger, and F is the water flow rate. It should be understood that this water flow rate can be the current water flow rate detected by the water flow sensor, or it can be the average of several water flow rate readings taken as the final determined water flow rate.

[0080] Step 103: Control the operation of the water heater according to the arrival time.

[0081] In this step, the control of the water heater mainly involves the proportional valve and the fan. The proportional valve regulates the gas output, indirectly affecting the heat exchange state of the heat exchanger; the fan regulates the air intake to provide sufficient air for gas combustion and / or to achieve wind resistance. Controlling the water heater based on arrival time allows for more precise control and avoids time lags in control.

[0082] Optionally, see Figure 4 Step 103 specifically includes the following steps:

[0083] Step 1031: Determine the start-up time threshold for the water heater based on the arrival time.

[0084] The water heater includes a controller, which is a device for controlling the water heater. In this disclosure, when the controller controls the components of the water heater, the controller will send instructions to make the components of the water heater execute the instructions. Optionally, the controller can be implemented by a microcontroller.

[0085] Regarding the determination of the start-up time threshold, the arrival time can be directly used as the start-up time threshold. This implementation method can greatly improve the precision of water heater control. Besides this, there are two other implementation methods:

[0086] The following is a method for determining the start-up time threshold: obtain the response coefficient of the water heater, and determine the start-up time threshold based on the response coefficient and the arrival time of the water heater. The response coefficient is used to characterize the speed at which the controller responds to start the water heater.

[0087] The following is another way to determine the start-up time threshold: obtain the start-up response time of the water heater, and determine the start-up time threshold based on the start-up response time and arrival time of the water heater. The start-up response time is the response time of the controller controlling the water heater.

[0088] The fundamental premise of both methods is based on the time difference inherent in the operation of the water heater. This time difference primarily includes two aspects: firstly, the time required between the flow sensor and the heat exchanger (the arrival time in this step); and secondly, the time required for the controller to process information, transmit signals through the circuitry to the water heater components, and for those components to execute the controller's instructions. This reaction time constitutes the startup response time in this step. Therefore, eliminating this time difference involves adjusting the startup time threshold based on these two aspects. This allows for more reasonable and precise control of the water heater, ensuring it burns under standard conditions and that exhaust emissions meet standards.

[0089] In one specific embodiment, the startup duration threshold can be calculated from the difference between the arrival time and the startup response time. For example, if the arrival time is 50ms and the startup response time is 5ms, then the startup duration threshold is 45ms. It should be understood that the startup response time can be obtained through theoretical calculations or statistical analysis of experimental data and can be adjusted according to actual needs.

[0090] In another specific embodiment, the startup time threshold can be calculated by multiplying the arrival time by the response coefficient. For example, if the arrival time is 50ms and the response coefficient is 0.9, then the startup time threshold is 45ms. It should be understood that the response coefficient can be obtained through theoretical calculations or statistical analysis of experimental data and can be adjusted according to actual needs.

[0091] Step 1032: If the accumulated time is greater than or equal to the start-up time threshold, then control the water heater to run. The accumulated time is the time accumulated from when the water heater receives the start-up command and begins timing.

[0092] In this step, the start-up duration threshold determined in step 1031 is used as the standard. When the accumulated duration is greater than or equal to the start-up duration threshold, the water heater is controlled to operate, so as to ensure the water heater operates at the right time.

[0093] Optionally, step 1032 specifically includes: obtaining the inlet water temperature and set temperature of the water heater; determining the load of the water heater based on the inlet water temperature, set temperature, and water flow rate; and determining the operating parameters of the water heater based on the load.

[0094] The operating parameters of the water heater can be specifically set according to the actual load during operation, so that the water heater can make specific adjustments based on these operating parameters. In one specific embodiment, the load can be calculated according to the following formula:

[0095] P = (T) set -T in )*F;

[0096] Where P is the load, T set To set the temperature, T in Inlet water temperature, F is water flow rate.

[0097] In addition, controlling the operation of a water heater also includes at least one of the following:

[0098] The proportional valve controlling the water heater is adjusted according to operating parameters. These operating parameters include those that control the opening degree of the proportional valve, such as the current intensity of the proportional valve.

[0099] The water heater's fan is adjusted according to operating parameters. These operating parameters include those controlling the fan speed.

[0100] The method described in this embodiment can make the timing of water heater control more reasonable and precise, and further make the temperature control of water heater more precise, so that water heater can burn according to standard combustion conditions, and further make exhaust gas emissions meet the standards.

[0101] To illustrate the control method of the water heater described above, a specific example is given below. Figure 5 It can be known that:

[0102] Step 1041, Begin.

[0103] Step 1042: Determine if the condition "the water heater is in operation" is met. If the determination is "yes", proceed to step 1043; if the determination is "no", proceed to step 1049.

[0104] Step 1043: Monitor the current water flow rate.

[0105] Step 1044: Calculate the load.

[0106] Step 1045: Calculate arrival time.

[0107] Step 1046: Calculate the cumulative duration.

[0108] Step 1047: Determine whether the condition "cumulative duration is greater than or equal to the startup duration threshold" is met. If the determination is "yes", proceed to step 1048; if the determination is "no", proceed to step 1046. The startup duration threshold is determined based on the product of the arrival time and the response coefficient.

[0109] Step 1048: Based on the load control proportional valve and fan, reset the accumulated duration to zero.

[0110] Step 1049, End.
