Embodiment Construction
[0053] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as recited in the appended claims.
[0054] In recent years, the popularization of domestic domestic gas has provided innate conditions for the promotion and application of gas water heaters. Gas water heaters, also known as gas water heaters, refer to the use of gas as fuel to transfer heat to the flow through the heat exchanger by means of combustion heating. A gas appliance for preparing hot water in cold water. Manufacturers ne...

The invention provides a testing method and testing equipment of a gas water heater and the gas water heater. The method comprises the steps that the gas water heater testing equipment sends a soft fire instruction to the gas water heater, the gas water heater is controlled to be tested in a soft fire mode, and when the heat of water reaches a first target heat value, whether the current value of a gas valve is within a first preset value range or not and whether the current values of a fan and a water pump exceed a current threshold value or not are tested. The test equipment updates the small fire instruction into a big fire instruction and sends the big fire instruction to the gas water heater, the gas water heater is controlled to be tested in a big fire mode, and when the heat of water reaches a second target heat value, whether the current value of a gas valve is within a second preset value range or not and whether the current values of a fan and a water pump exceed a current threshold value or not are tested. According to the method, the test device sends the small fire instruction and the big fire instruction to the gas water heater to complete the test of the gas water heater in the small fire mode and the big fire mode, and the test efficiency and the test result accuracy of the gas water heater are improved.
Description
technical field [0001] The present application relates to the technical field of gas water heater testing, in particular to a gas water heater testing method, testing equipment and gas water heater. Background technique [0002] Gas water heater refers to a device that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water. Before mass production and manufacture of gas water heaters, the calorific value of gas water heaters needs to be tested. [0003] In the prior art, when the calorific value of the gas water heater is tested, the water flow and air volume are preset, and then the tester manually toggles the flame control DIP switch, selects the low-fire modulation mode or the high-fire modulation mode, and then rotates the flame control DIP switch manually. The potentiometer controls the solenoid valve current used in the low-fire modulation test or the solenoid valve cur...
