[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 and Figure 2 As shown, this embodiment relates to a testing system for gas stoves and a gas stove using the testing system. The gas stove includes a burner 10, an intake pipe 10b communicating with the burner 10, and an ignition needle 10a for igniting the burner 10. The structure of the gas stove in this embodiment is prior art and will not be described in detail here. Figure 2 The image shown only illustrates some of the components of a gas stove.

[0027] The testing system for gas stoves in this embodiment includes a thermocouple 1, a pressure regulating valve 2, a controller 3, a pressure stabilizing valve 4, an infrared temperature measuring device 5, a cooling device 6, and a display unit 9. Figure 2 As shown, both the pressure regulating valve 2 and the pressure stabilizing valve 4 are located on the air intake pipe 10b, with the pressure stabilizing valve 4 located downstream of the pressure regulating valve 2. The controller 3 is electrically connected to the pressure regulating valve 2, the thermocouple 1, the infrared temperature measuring device 5, the cooling device 6, and the display unit 9. The infrared temperature measuring device 5 is used to measure the temperature of the thermocouple 1, which is located near the periphery of the burner head 10. The infrared temperature measuring device 5 is positioned above the burner head 10 and can also be used to detect whether the burner head 10 is cold. The cooling device 6 is used to cool the burner head 10 and the thermocouple 1. The infrared temperature measuring device 5 in this embodiment uses existing technology and will not be described in detail here. The cooling device 6 can use existing cooling devices, such as fans. The display unit 9 can be a touch screen.

[0028] The controller 3 is also electrically connected with a power supply module 7 for power supply and a voltage acquisition module 8, the power supply module 7 is configured with different power supplies to meet the working of the ignition needle 10a of multiple different voltages, and also can test the change of the electromotive force after the voltage of the battery is reduced to 1.05V or 2.1V; the voltage acquisition module 8 is used for acquiring the voltage after the burner 10 is ignited.

[0029] The working process of the test system in the embodiment is as follows:

[0030] The controller adjusts the pressure regulating valve to the set pressure value according to different air inlet pipelines (natural gas needs three pressures of 1.5kPa, 2.0kPa and 2.8kPa, and liquefied gas needs three pressures of 2.0kPa, 2.8kPa and 3.3kPa), and the controller controls the power supply device to output the set voltage value according to different ignition needles (the ignition needle has multiple types of 220V, 1.5V and 3.0V), then ignition test is performed, at this time, the voltage acquisition module acquires the voltage condition after ignition and displays on the display unit 9; and the voltage acquisition module starts to record the electromotive force curve through the temperature change synchronous clock of the infrared temperature measuring device, then the electromotive force is monitored in the stages of ignition, stable fire and fire-off of the stove, and because the stoves are different, one type is selected for the electromotive force determination as an example:

[0031] The ignition electromotive force is greater than or equal to 2mv under three gas pressures, whether the ignition time meets the requirement of 1s, and whether the thermocouple temperature is less than or equal to 650℃;

[0032] The stable fire electromotive force is greater than or equal to 5mv under three gas pressures, whether the stable time meets the requirement of less than or equal to 3s through the acquisition instrument, whether the requirement is met, and whether the thermocouple temperature is less than or equal to 650℃;

[0033] The fire-off electromotive force is less than or equal to 0.5mv under three gas pressures, whether the fire-off time meets the requirement of 60s, and whether the thermocouple temperature is less than or equal to 650℃;

[0034] Because each test can only test one group of data, and the stove needs to be cooled before testing, therefore, the cooling device is started to cool the burner and the thermocouple after each test, the feedback is fed back through the infrared temperature measuring device 5, and the test efficiency is improved. The above test electromotive force and determination method are repeated to realize the accurate test of the electromotive force, so as to finally realize the accurate control of the gas stove.

[0035] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and decorations can be made without departing from the technical principles of the present application, and these improvements and decorations should also be regarded as the protection range of the present application.
