[0002] A gas water heater is a device that uses gas as fuel and heats water by transferring heat to cold water flowing through a heat exchanger. Before mass production and manufacturing gas water heaters, their calorific value needs to be tested.

[0003] In existing technologies, when testing the calorific value of a gas water heater, the water flow rate and air volume are preset. Then, the tester manually toggles the flame control DIP switch to select either a low-fire modulation mode or a high-fire modulation mode. The current of the solenoid valve used for the low-fire modulation test or the high-fire modulation test is then controlled by rotating a potentiometer. When the calorific value of the gas water heater reaches the target calorific value, the tester determines whether the current of the solenoid valve is within the preset current value range.

[0052] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0053] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0054] In recent years, the widespread use of domestic gas has provided favorable conditions for the promotion and application of gas water heaters. Gas water heaters, also known as gas-fired water boilers, are gas appliances that use gas as fuel and heat water by transferring heat to cold water flowing through a heat exchanger. Manufacturers need to test gas water heaters before mass production and manufacturing them.

[0055] In existing technology, when testing gas water heaters, the water flow rate and air volume are preset. Then, the tester manually toggles the flame control DIP switch to select either a low-fire modulation mode or a high-fire modulation mode. The current of the solenoid valve used for the low-fire modulation test or the high-fire modulation test is then controlled by rotating a potentiometer. When the calorific value of the gas water heater reaches the target calorific value, it is determined whether the current of the solenoid valve is within the preset current value range. If the current of the solenoid valve is within the preset current value range, the gas water heater passes the test.

[0056] However, when existing technologies are used for manual testing, the testing efficiency is low and the testing time is long because the tester needs to operate the testing instrument multiple times and rotate the potentiometer multiple times to adjust the current of the solenoid valve used for testing. In addition, since the water flow and air volume are preset during the testing process, automatic control cannot be achieved, resulting in poor accuracy of the test results.

[0057] Therefore, in view of the above-mentioned technical problems of the prior art, this application proposes a testing method, testing equipment, and a gas water heater. The gas water heater testing equipment sends a test command, and after receiving the test command, the gas water heater performs the test. The test command includes a low-fire command and a high-fire command, and the high-fire command is updated based on the test data obtained after the low-fire modulation test. The test data includes the solenoid valve current value, the fan current value, and the water pump current value. The test process includes a low-fire mode test process and a high-fire mode test process.

[0058] This application can be applied to various types of gas water heater calorific value testing scenarios, such as gas water heaters using manufactured gas, natural gas, or liquefied petroleum gas as fuel. It utilizes gas water heater testing equipment to perform automated calorific value testing of the gas water heaters. It is understood that the gas water heater testing method, testing equipment, and gas water heater provided in this application include, but are not limited to, the types of gas water heaters mentioned above, and are not intended to limit this application.

[0059] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0060] Figure 1 This is a flowchart illustrating a testing method for a gas water heater provided in Embodiment 1 of this application. The method can be executed by a gas water heater testing device, wherein the test includes tests in low-fire mode and tests in high-fire mode, such as... Figure 2 As shown, the method may include the following steps:

[0061] S101. Send a low-fire command to the gas water heater under test. The low-fire command is used for the gas water heater to work in low-fire mode. When the heat of the water reaches the first target heat value, test whether the current value of the gas valve is within the first preset value range, whether the current value of the fan exceeds the fan current threshold, and whether the current value of the water pump exceeds the water pump current threshold.

[0062] The execution subject of this embodiment is a gas water heater testing device. This testing method can be implemented through software, hardware, or a combination of both. Specifically, the gas water heater testing device communicates with the gas water heater under test via electrical signals. The testing device sends a small-flame command to the gas water heater under test. This small-flame command is sent from the testing device to the computer control board of the gas water heater, and the computer control board controls the gas water heater to perform relevant actions according to the command.

[0063] In the testing equipment, the preset current of the gas valve in the gas water heater (i.e., the first preset value), the preset current of the fan (i.e., the fan current threshold), and the preset current of the water pump (i.e., the water pump current threshold) are preset when the calorific value of the water in the gas water heater reaches the first target calorific value.

[0064] Calorific value refers to the amount of heat released when a unit mass (or volume) of fuel is completely burned. In this application, the calorific value can be calculated by detecting the water temperature and flow rate in a gas water heater, for example, using the following formula:

[0065] Calorific value = (Preset temperature - Supply water temperature) * Water flow rate / 25

[0066] The units for water flow rate are liters per liter (L), temperature is degrees Celsius per ℃, and calorific value is joules per cubic meter (J / m³). 3 .

[0067] In addition, calorific value can also be obtained directly by measuring with a calorific value meter. It should be noted that there are many ways or devices to obtain calorific value, which will not be listed here. The methods exemplified in this application shall not be construed as limiting this application.

[0068] The opening degree of the gas valve determines the amount of gas entering the gas water heater. The valve opening degree is related to the control current it receives; the higher the current, the wider the opening. Therefore, the gas valve also has a protective function, capable of cutting off the gas supply. The fan supplies air to the gas water heater; the higher the fan speed, the more air enters. The fan speed is related to the control current it receives; the higher the current, the higher the speed. The water pump determines the water flow rate into the gas water heater; the higher the water pump speed, the greater the water flow rate. The water pump speed is related to the control current it receives; the higher the current, the higher the speed.

[0069] S102: Receive the current values ​​of the gas valve, fan, and water pump when the heat of the water sent by the gas water heater reaches the first target calorific value, and update the low-fire command to a high-fire command based on the current values ​​of the gas valve, fan, and water pump.

[0070] The gas water heater testing equipment sends a low-fire command to the gas water heater. After receiving the low-fire command, the gas water heater starts configuring the modulation parameters according to the command information to conduct the test in low-fire mode.

[0071] The instructions in the small fire command include, but are not limited to, the following: the first target calorific value, the first current value of the gas valve, the first current value of the fan, and the first current value of the water pump.

[0072] According to the low-fire command, the gas water heater configures the first current values ​​of the water pump, fan, and gas valve to control the first water flow, first air volume, and first gas volume entering the gas water heater. Then, based on the first water flow, first air volume, and first gas volume, it adjusts the water pump current value, fan current value, and gas valve current value to heat the water to the first target calorific value. At the same time, it detects the current values ​​of the water pump current value, fan current value, and gas valve current value and sends them to the gas water heater testing equipment.

[0073] Furthermore, the gas water heater testing equipment checks whether the gas water heater passes the test when operating in low-fire mode based on the received current values ​​from the gas valve, fan, and water pump. If it passes, the low-fire command is updated to a high-fire command.

[0074] S103. Send a high-fire command to the gas water heater. The high-fire command is used for the gas water heater to operate in high-fire mode. When the heat value of the water reaches the second target heat value, test whether the current value of the gas valve is within the second preset value range, whether the current value of the fan exceeds the fan current threshold, and whether the current value of the water pump exceeds the water pump current threshold.

[0075] Similarly, in the testing equipment, a preset current of the gas valve in the gas water heater is set to the second preset value when the calorific value of the water in the gas water heater reaches the second target calorific value.

[0076] S104. Receive the current values ​​of the gas valve, the fan, and the water pump when the water heat reaches the second target calorific value sent by the gas water heater.

[0077] The gas water heater testing equipment sends a high-fire command to the gas water heater. After receiving the high-fire command, the gas water heater begins to configure the modulation parameters according to the instruction information in the high-fire command to conduct the test in high-fire mode.

[0078] The fire command includes, but is not limited to, the following: second target calorific value, second current value of gas valve, second current value of fan, and second current value of water pump.

[0079] According to the fire command, the gas water heater configures the second current values ​​of the water pump, fan, and gas valve to control the second water flow, second air volume, and second gas volume entering the gas water heater. Then, based on the second water flow, second air volume, and second gas volume, it adjusts the water pump current value, fan current value, and gas valve current value to heat the water to the second target calorific value. At the same time, it detects the current values ​​of the water pump current value, fan current value, and gas valve current value and sends them to the gas water heater testing equipment.

[0080] Furthermore, the gas water heater testing equipment detects whether the gas water heater passes the test when operating in high-fire mode based on the received current values ​​of the gas valve, the fan, and the water pump.

[0081] In the above embodiments of this application, the gas water heater testing equipment first sends a low-fire command to the gas water heater to control it to perform testing in low-fire mode. When the water heat reaches a first target calorific value, the equipment tests whether the current value of the gas valve is within a first preset value range, whether the current value of the fan exceeds a fan current threshold, and whether the current value of the water pump exceeds a water pump current threshold. The gas water heater operates in low-fire mode. When the water heat reaches the first target calorific value, it detects the current values ​​of the gas valve, fan, and water pump and sends them to the gas water heater testing equipment. Based on the received current values ​​of the gas valve, fan, and water pump, the testing equipment checks whether the test in low-fire mode has passed. Simultaneously, the testing equipment updates the low-fire command to a high-fire command and sends it to the gas water heater to control it to perform testing in high-fire mode. When the water heat reaches a second target calorific value, the equipment tests whether the current value of the gas valve is within a second preset value range, whether the current value of the fan exceeds a fan current threshold, and whether the current value of the water pump exceeds a water pump current threshold. In high-fire mode, when the water heat reaches the second target calorific value, the gas water heater detects and sends the current values ​​of the gas valve, fan, and water pump to the gas water heater testing equipment. The testing equipment then determines whether the high-fire mode test has passed based on the received current values. This embodiment improves the testing efficiency and accuracy of the gas water heater by sending low-fire and high-fire commands to the gas water heater through the testing equipment.

[0082] Furthermore, based on the above-described Embodiment 1, the test method for gas water heaters will be described in detail below through Embodiment 2, which includes the test process of the gas water heater in low flame mode and the test process in high flame mode.

[0083] like Figure 2As shown, Figure 2 This is a flowchart illustrating another testing method for a gas water heater provided in Embodiment 2 of this application. The method includes the following steps:

[0084] S201, Send a small flame command to the gas water heater under test.

[0085] The gas water heater testing equipment sends a low-fire command to the gas water heater. After receiving the low-fire command, the gas water heater modulates the parameters according to the command information in the low-fire command to conduct the test in low-fire mode.

[0086] According to the low-fire command, the gas water heater configures the first current value of the water pump, the first current value of the fan, and the first current value of the gas valve to control the first water flow, the first air volume, and the first gas volume entering the gas water heater. Then, based on the first water flow, the first air volume, and the first gas volume, the water pump current value, the fan current value, and the gas valve current value are adjusted to heat the water to the first target calorific value.

[0087] S202, Receive the current values ​​of the gas valve, fan, and water pump sent by the gas water heater when the heat of the water reaches the first target calorific value.

[0088] When the water is heated to the first target calorific value, the gas water heater detects the current water pump current value, fan current value, and gas valve current value and sends them to the gas water heater testing equipment.

[0089] S203. Test whether the current value of the gas valve is within the first preset value range, whether the current value of the fan exceeds the fan current threshold, and whether the current value of the water pump exceeds the water pump current threshold in the low flame mode.

[0090] The gas water heater testing equipment receives the current values ​​of the gas valve, the fan, and the water pump, and compares them with the pre-set first preset value of the solenoid valve, the fan current threshold, and the water pump current threshold to make a judgment.

[0091] The setting of the first preset value is related to the model of the gas water heater and the type of gas valve used. The setting of the fan current threshold is related to the fan type, and the setting of the water pump current threshold is related to the water pump type. These settings can be made according to the actual usage.

[0092] S204. If the current value of the gas valve is within the first preset value range, and the current value of the fan does not exceed the fan current threshold and the current value of the water pump does not exceed the water pump current threshold, then the test of the gas water heater working in low flame mode is passed, and step S205 is executed.

[0093] If the current value of the gas valve exceeds the first preset value range, or the current value of the fan exceeds the fan current threshold or the current value of the water pump exceeds the water pump current threshold, then the small flame command is sent to the gas water heater repeatedly a preset number of times, and step S201 is executed a preset number of times.

[0094] S205. Update the small fire command to a large fire command.

[0095] The gas water heater testing equipment updates the gas valve current value, fan current value, and water pump current value in the low-fire command to the current values ​​corresponding to the gas valve, fan, and water pump when the water is heated to the first target calorific value.

[0096] S206, Send a high-fire command to the gas water heater.

[0097] The gas water heater testing equipment sends a high-fire command to the gas water heater. After receiving the high-fire command, the gas water heater modulates the parameters according to the command information in the high-fire command to conduct the test in high-fire mode.

[0098] According to the fire command, the gas water heater configures the second current value of the water pump, the second current value of the fan, and the second current value of the gas valve to control the second water flow, the second air volume, and the second gas volume entering the gas water heater. Then, based on the second water flow, the second air volume, and the second gas volume, the water pump current value, the fan current value, and the gas valve current value are adjusted to heat the water to the second target calorific value.

[0099] S207 Receive the current values ​​of the gas valve, the fan, and the water pump sent by the gas water heater when the heat of the water reaches the second target calorific value.

[0100] When the water is heated to the second target calorific value, the gas water heater detects the current water pump current value, fan current value, and gas valve current value and sends them to the gas water heater testing equipment.

[0101] S208. Test whether the current value of the gas valve is within the second preset value range, whether the current value of the fan exceeds the fan current threshold, and whether the current value of the water pump exceeds the water pump current threshold under the high-fire mode.

[0102] The gas water heater testing equipment receives the current values ​​of the gas valve, the fan, and the water pump, and compares them with pre-set second preset values, fan current thresholds, and water pump current thresholds to make a judgment.

[0103] The setting of the second preset value is related to the model of the gas water heater and the type of gas valve used. The setting of the fan current threshold is related to the fan type, and the setting of the water pump current threshold is related to the water pump type. These settings can be made according to the actual usage.

[0104] S209. If the current value of the gas valve is within the second preset value range, and the current value of the fan does not exceed the fan current threshold and the current value of the water pump does not exceed the water pump current threshold, then the test of the gas water heater operating in the high-fire mode is passed, and the gas water heater test is completed.

[0105] If the current value of the gas valve exceeds the second preset value range, or the current value of the fan exceeds the fan current threshold or the current value of the water pump exceeds the water pump current threshold, the preset number of steps S206 is executed.

[0106] It is understandable that steps S201-S204 are the testing process of the gas water heater in low-fire mode, and steps S205-S209 are the testing process of the gas water heater in high-fire mode.

[0107] In the above-described second embodiment of this application, the testing process of the gas water heater in low-fire mode and high-fire mode is described in detail, illustrating the testing process of the gas water heater. The method of this embodiment completes the testing of the gas water heater in low-fire mode and high-fire mode by sending low-fire and high-fire commands to the gas water heater through the gas water heater testing equipment, which not only improves the testing efficiency but also improves the accuracy of the test results.

[0108] It is particularly important to note that before the gas water heater testing equipment sends a small flame command to the gas water heater, it is also necessary to ensure that the port communication of each module of the gas water heater itself is fault-free and can communicate normally. Figure 3 As shown, the main instrument used is a gas water heater testing device. Figure 3 This is a flowchart illustrating a method for determining normal communication at the port of a gas water heater, as provided in Embodiment 2 of this application.

[0109] Specifically,

[0110] S301. Send test instructions for each module to the gas water heater. The modules include at least one of the following: gas valve, fan, water pump, etc.

[0111] By testing the water pump, it was confirmed that the water pump communication was normal; by testing the fan, it was confirmed that the fan communication was normal; by testing the water pump, it was confirmed that the water pump communication was normal. It can also test related modules such as gas valves, fans, and water pumps, including water flow modules, flame combustion modules, temperature detection modules, and alarm modules.

[0112] By detecting the water flow module, it is confirmed that the water flow module is communicating normally, allowing water to flow into the gas water heater and detecting the outflow rate. By detecting the flame combustion module, it is confirmed that the flame combustion module is communicating normally, allowing the gas water heater to ignite normally. By detecting the temperature detection module, it is confirmed that the temperature detection module is communicating normally, allowing the gas water heater to measure temperature (in this application, this can refer to water temperature). By detecting the alarm module, it is confirmed that the alarm module is communicating normally, allowing the gas water heater to sound an alarm normally, etc. It is understood that the modules listed in this embodiment should not be construed as limiting this application; any module that requires communication with the gas water heater can fall within the scope of protection of this application.

[0113] S302: Receive the basic voltage of each module detected by the gas water heater according to the test command.

[0114] According to the test instructions, the gas water heater detects the basic voltage of each module and sends the detected basic voltage to the gas water heater test equipment.

[0115] S303. Based on the base voltage of each module, check whether the port communication of each module is normal.

[0116] Different modules have different base voltages when their ports are communicating normally. In order to detect whether the port communication of different modules is normal, the gas water heater testing equipment has pre-set the base voltage threshold value corresponding to the normal communication of each module.

[0117] If the base voltage of each module is within the preset voltage threshold value for each module as set in the gas water heater testing equipment, then the port communication of each module is normal.

[0118] If the base voltage of each module exceeds the preset voltage threshold value range of each module in the gas water heater testing equipment, step S301 is executed a preset number of times.

[0119] In addition, the gas water heater testing equipment can also receive load signals and test process operation status data of each module after the gas water heater is tested. The load can be gas valve, fan, water pump, valve relay, and read valve, water flow, water servo, etc.

[0120] If the load signal and test process operation status data can be read, the gas water heater test equipment will automatically power off; or, if the load signal and test process operation status data cannot be read, a corresponding read fault code will be generated. The read fault code is used by test personnel to troubleshoot the corresponding gas water heater test equipment fault.

[0121] In the above embodiments of this application, the basic voltage of each module of the gas water heater is detected to ensure that the port communication of each module of the gas water heater is normal.

[0126] Based on the first current value of the water pump, the speed of the water pump is controlled, and the first water flow rate entering the gas water heater is detected.

[0130] Specifically:

[0131] Based on the detected first water flow rate, first air volume, and first gas volume, the required water flow rate, air volume, and gas volume are calculated to heat the water in the gas water heater to the first target calorific value. The calculation method can be based on a pre-stored calculation program or a pre-stored calculation formula in the gas water heater's computer control board.

[0132] Adjust the water pump current, fan current, and gas valve current based on the calculated water flow, air volume, and gas volume.

[0133] Based on the adjusted current values ​​of the water pump, fan, and gas valve, the rotation speeds of the water pump, fan, and gas valve are controlled to heat the water to the first target calorific value.

[0134] S403. The current values ​​of the gas valve, the fan, and the water pump when the heat of the water sent to the gas water heater testing equipment reaches the first target calorific value.

[0135] S404 Receives a fire command sent by the gas water heater testing equipment.

[0136] The gas water heater testing equipment updates the gas valve current value, fan current value, and water pump current value in the low-fire command to the current values ​​corresponding to the gas valve, fan, and water pump when the water's calorific value is heated to the first target calorific value. This updates the low-fire command to a high-fire command and sends it to the gas water heater. S405: Based on the high-fire command, the gas water heater is controlled to operate in high-fire mode, and when the water's heat reaches the second target calorific value, the current values ​​of the gas valve, fan, and water pump are detected. Based on the high-fire command, the second current values ​​of the gas water heater's water pump, fan, and gas valve are configured to control the second water flow rate, second air volume, and second gas volume entering the gas water heater.

[0137] Specifically:

[0139] When the detected second water flow rate reaches the preset water flow rate corresponding to the second current value of the water pump, the fan speed is controlled according to the second current value of the fan, and the second air volume entering the gas water heater is detected.

[0140] Based on the second current value of the gas valve, the opening degree of the gas valve is controlled, and the second gas volume entering the gas water heater is detected.

[0141] Based on the second water flow rate, second air volume, and second gas volume, adjust the water pump current value, fan current value, and gas valve current value to heat the water in the gas water heater to the second target calorific value.

[0147] In the above embodiments of this application, after receiving a low-fire command from the gas water heater testing equipment, the gas water heater operates in low-fire mode according to the command. When the water heat reaches the first target calorific value, the current values ​​of the gas valve, fan, and water pump are detected and sent to the gas water heater testing equipment, facilitating the testing equipment's assessment of whether the gas water heater has passed the low-fire mode test. After receiving a high-fire command from the gas water heater testing equipment, the gas water heater operates in high-fire mode according to the command. When the water heat reaches the second target calorific value, the current values ​​of the gas valve, fan, and water pump are detected and sent to the gas water heater testing equipment, facilitating the testing equipment's assessment of whether the gas water heater has passed the high-fire mode test. This embodiment's method, by having the gas water heater testing equipment send low-fire and high-fire commands to the gas water heater to complete the testing of the gas water heater in low-fire and high-fire modes, not only improves testing efficiency but also enhances the accuracy of test results.

[0148] It is particularly important to note that before the gas water heater receives the small flame command from the gas water heater testing equipment, it also needs to send the basic voltage of each module to the testing equipment. This allows the testing equipment to verify that the gas water heater's port communication is functioning correctly and can communicate normally. Figure 5 As shown, its main actuator is a gas water heater. Figure 5 This is a flowchart illustrating another method for determining that the port communication of a gas water heater is normal, provided in Implementation 5 of this application.

[0149] Specifically,

[0150] S501 Receive test instructions for each module sent by the gas water heater testing equipment. The modules include at least one of the following: gas valve, fan, water pump, etc.

[0151] By testing the water pump, it was confirmed that the water pump communication was normal; by testing the fan, it was confirmed that the fan communication was normal; by testing the water pump, it was confirmed that the water pump communication was normal. It can also test related modules such as gas valves, fans, and water pumps, including water flow modules, flame combustion modules, temperature detection modules, and alarm modules.

[0152] By testing the water flow module, it was confirmed that the water flow module is communicating normally, water can flow into the gas water heater normally, and the water flow rate can be detected; by testing the flame combustion module, it was confirmed that the flame combustion module is communicating normally, and the gas water heater can ignite normally; by testing the temperature detection module, it was confirmed that the temperature detection module is communicating normally, and the gas water heater can measure the temperature, which in this application may refer to the water temperature; by testing the alarm module, it was confirmed that the alarm module is communicating normally, and the gas water heater can alarm normally, etc.

[0155] S503, Send the basic voltage of each module to the gas water heater testing equipment.

[0156] In addition, the gas water heater can also send load signals of each module after the test and the operating status data of the test process to the gas water heater testing equipment. The load can be gas valve, fan, water pump, valve relay, reading valve, water flow, water servo, etc.

[0157] If the gas water heater testing equipment can read the load signal and the test process operation status data, the gas water heater testing equipment will automatically shut off the power; if it cannot read the load signal and the test process operation status data, a corresponding reading fault code will be generated. The reading fault code is used by the test personnel to troubleshoot the corresponding gas water heater testing equipment fault.

[0158] In the above embodiments of this application, the gas water heater detects the base voltage of each module and sends it to the gas water heater testing equipment. This allows the testing equipment to detect whether the port communication of each module of the gas water heater is normal.
