Title: Hot water serving pot
Inventor: TAKESHITA TOSHIHIKO
IPC: F24H1/06
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To reliably prevent the flowout of hot water from a spout when a pot fall down. SOLUTION: In a shut-off valve unit 10 provided on the upper end of a hot water spout 9, by pressing a valve 29, into the periphery of which an O-ring 30 is fitted, against a conical valve seat 23 by the urging force of a spring 32, the valve is closed, and when serving hot water, the rising pressure of hot water opens the valve. When the valve is closed after hot water is served, hot water remaining upward of the valve seat 23 flows downward through inverted conical water passing holes 25. In case the pot falls down, closing by ring-shaped sheets 37 and the shape of the water passing holes 25 themselves prevent hot water from leaking backward, whereby outflow of hot water can be prevented even if the pot falls down.

These signals are then amplified by amplifiers 31 and 32 and only a waveform component of the difference between the welding current waveforms at the plus side and the minus side is taken out through a waveform subtracter 9. The influence of a low frequency component is then reduced and the effective value is obtained by an RMS circuit 11 by passing the waveform of the difference through a high-pass filter 10. Since this effective value becomes higher when the gas shielded state is defective, size of this effective value is detected by a determination circuit 12 and when it exceeds a specified value, a signal is produced and an alarm is produced by an alarm circuit 13.
