Vapor metal sheet 4 all can be set fixing operating temperature respectively according to needs with anti-dry sheet metal 9 when making; Steam temperature or electrothermal tube protruding part temperature reach corresponding design temperature; Vapor metal sheet 4 or anti-dry sheet metal 9 will move, and touch corresponding component.
Under the non operating state, the contact of the silver contact of L utmost point active and static contact; The safety post 11 roof pressure safety springs 12 that contact with electrothermal tube Flange Plane position, the N utmost point movable contact spring 18 that is connected with safety spring 12 is pressed down by the pulling of safety spring, and this moment, the silver contact of N utmost point active and static contact contacted; Anti-dry catch bar 10 is place's non operating state temporarily; Button 5 is in non operating state, and steam catch bar 7 is pressed down by button 5 power, touches N utmost point movable contact spring 18, and N utmost point active and static contact silver contact separates.At this moment, even energized, because of N utmost point active and static contact silver contact separates, circuit is in off-state.
Energized pushes button 5, and with the 5 support end perks of steam catch bar 7 corresponding key, steam catch bar 7 takeoffs under no pressure condition at this moment, and N utmost point movable contact spring 18 contacts with N utmost point static contact 14 silver contacts under the downforce effect of having only safety spring 12.The circuit debugging that two thermostats and electrothermal tube are formed, electrothermal tube energising heating is heated up water, and the neon lamp that play indicative function parallelly connected with electrothermal tube lights for 20 this moments.When water is heated to when boiling, spray outside the steam hole place that steam is offered through conduit to kettle body, the vapor metal sheet 4 corresponding with steam hole is heated, when reaching its operating temperature that sets firmly, vapor metal sheet 4 springing of being heated, and touch the corresponding long fulcrum of holding of button 5.Button 5 resets through the elastic force effect of the spring leaf 6 that sticks; This moment, button 5 other end fulcrums touched steam catch bar 7; It is pressed down, touch N utmost point movable contact spring 18, N utmost point active and static contact silver contact separates; Thereby the circuit that two thermostats and electrothermal tube are formed breaks off, and the neon lamp 20 that plays indicative function extinguishes.Electrothermal tube outage stopping heating, these promptly two normal water of temperature-control electric kettle socket are opened automatic circuit break function.
Under the situation of anhydrous or water level not submergence on the low side electrothermal tube, press button 5, in the kettle though steam catch bar 7 takeoffs; The silver contact contact of N utmost point active and static contact, the circuit debugging that two thermostats and electrothermal tube are formed, but because electrothermal tube can not get the cooling of water; Its temperature raises rapidly, and 9 inductions of the anti-dry sheet metal that contacts with the electrothermal tube protruding part are heated, when temperature reach the anti-dry sheet metal set firmly temperature the time; Anti-dry sheet metal 9 springing of being heated; Promote anti-dry catch bar 10, anti-dry catch bar 10 presses down and touches L utmost point movable contact spring 15, and the silver contact of L utmost point active and static contact is separated; Thereby the circuit that two thermostats and electrothermal tube are formed breaks off, electrothermal tube outage stopping heating.
The more a lot of safe outage effects of the anti-dry function of anti-dry sheet metal 9 and anti-dry catch bar 10 to prompting or short-term.Under the situation that long-time unattended electric kettle uses, the safety effect of this kind anti-dry control is limited.In case the temperature of electrothermal tube protruding part descends, anti-dry sheet metal 9 will reset, and anti-dry catch bar 10 is in non operating state, the silver contact contact of L utmost point active and static contact, and circuit debugging, electrothermal tube energising heating, the anti-dry action will constantly repeat.Continue for a long time, will make the too fast aging or damage of parts, the probability that security incident takes place rises.This kind situation or be heated springing when slow when anti-dry sheet metal 9; Safety post 11 fusings that contact with electrothermal tube Flange Plane position; Safety post length after the fusing shortens, and the former safety spring 12 that pressed down by safety post 11 is upspring under the non-pressure state, and N utmost point movable contact spring 18 was opened by the tension of safety spring and N utmost point static contact in 14 minutes; Circuit thoroughly breaks off, and electrothermal tube stops heating.The safety post safety effect of these promptly two temperature-control electric kettle sockets is realized multiple protective, effectively prevents the security incident that socket temperature control part fails causes.
