METHOD AND DEVICE FOR CHECKING GAS-STOVE BURNER FLAME |
摘要 |
FIELD: domestic gas stoves including those provided with safety devices shutting off gas supply in case of failure of flame. SUBSTANCE: flame sensor is made in the form of adjustable metal electrode that checks conductivity of burner-to-electrode air gap and sends signal to electronic amplifier and from the latter, to hold-up coil of electromagnetic valve feeding gas to burner. Effective part of check-op electrode is 1.5 to 3 mm in diameter and has tip pointed at angle of 30 to 60 deg.; electronic amplifier circuit incorporates time- setting capacitor that ensures delay of gas shut-off in case of failure of flame and warning device indicating operation of shut-off unit. EFFECT: improved reliability of flame check-up system. 4 cl, 2 dwg
