Automatic control test device of gas cooker

Abstract

The invention discloses an automatic control test device of a gas cooker. A working circuit of the device comprises a main control unit, and a display unit, a control unit, a temperature collection unit, an analog input unit and an analysis processing unit, which are respectively and electrically connected with the main control unit, wherein the control unit comprises a program logic controller (PLC), a gas flow meter which is electrically connected with the PLC, a gas pressure regulating valve, a stirrer and a gas on-off valve; the temperature collection unit comprises a gas temperature collection unit, an ambient temperature collection unit, a smoke temperature collection unit and a hot water temperature collection unit; the analog input unit comprises a gas pressure input unit and an atmosphere pressure input unit; and the analysis processing unit comprises a smoke composition analyzer and a heat radiation collection instrument. The automatic control test device of the gas cooker has advantages of compactness in structure, high safety, simpleness and convenience in testing, good test effect, reliability in test data and the like.

Description

Technical field: [0001] The invention relates to the technical field of testing equipment, in particular to an automatic control testing equipment for a gas stove with compact structure, high safety and excellent testing effect. Background technique: [0002] Kitchen gas stoves have now become an indispensable part of daily household appliances and a must-have for every family, especially for every household in cities. Gas is a highly flammable and explosive substance, so the quality requirements of gas cooker products are particularly high, because it will directly affect the safety of life and property. [0003] Household gas cookers are generally composed of a gas supply system, a combustion system, a control system, an ignition system, and other components. The gas supply system includes gas delivery pipes and gas valves. The combustion system is mainly composed of a burner, which is composed of a nozzle, an air regulating plate, an ejector, a burner head, and a fire c...

AI Technical Summary

Problems solved by technology

The technical solutions disclosed in these patent documents are all to install corresponding safety detection devices on the gas cooker, but none of them proposes that after the gas cooker is produced, comprehensive testing should be carried out on the products before leaving the factory to detect each of the gas cooker products. Whether the item performance index is qualified

[0005] At present, manufacturers of gas cookers are also constantly improving the test conditions of their products, and have purchased and made some test equipment for parts. The result does not mean that the entire gas cooker is a qualified product. Factors such as design, manufacture, and use environment such as high temperature generated by combustion affect the quality of the whole machine. Some manufacturers even use manual operation, which has very low test efficiency and unreliable test data.
