During use, just in case anhydrous dry combustion method phenomenon appears, then the meeting of the normally-closed contact on the overheat protector (14) automatic disconnection, so the outage of heating major loop; The heating major loop is in case outage; heat then that no current passes through in the major loop; signal acquisition circuit obtains with regard to no signal current; signal processing circuit will be sent open command; heating start and stop executive circuit will make the line bag outage of relay CJ; so the normally opened contact of CJ-1 and CJ-2 disconnects earlier; closed behind its normally-closed contact; be that socket (1) disconnects from the N line and the L line of municipal electrical network earlier; receive again on the load detecting circuit that adopts safe voltage; make socket (1) be in electric safe condition, and keep this electric safe condition and reset up to overheat protector (14); temperature controller (13) resets and the user ends when pressing the heating starting switch once more.
The safe drinking machine of the utility model Tape movement electric water-heating cup, when the temperature in the electric water-heating cup rises to design temperature, temperature controller (13) take-off, the heating major loop cuts off the power supply automatically, also outage automatically of electric water-heating cup power source special socket (1) simultaneously, and after a period of time, when the water temperature in the cup drops to temperature controller (13) when resetting, the heating of also can not switching on automatically of heating major loop.Like this, both can prevent that water in the cup from dryouting and security incident occurs, can prevent again that water in the cup from being heated repeatedly and become " thousand boiling water ".
The beneficial effect of the safe drinking machine of the utility model Tape movement electric water-heating cup is:
1. when water fountain was in holding state, the electric water-heating cup power source special socket (1) on it was electric safe condition.
2. when electric water-heating cup was heating, in a single day its attaching plug left its power source special socket (1), and then the voltage on the socket (1) is reduced to safe voltage at once, made socket (1) be in electric safe condition.
3. when temperature controller (13) or overheat protector (14) take-off, disconnecting the heating main circuit power, the power source special socket (1) of electric water-heating cup also cuts off the power supply, and makes socket (1) be in electric safe condition.
4. after the water temperature in the cup is reduced to the lower limit temperature of temperature controller (13) from high temperature, temperature controller (13) resets, and electric water-heating cup power source special socket (1) still keeps electric safe condition, can not heat automatically, both can prevent water in the cup from dryouting and security incident occurred, can prevent again that water in the cup from being heated repeatedly and become " thousand boiling water ".
5. when the electric water-heating cup plug did not insert its private jack (1), water pump can not start, and can prevent that the user from opening by mistake depotition cock, caused security incident.
