Described suction brandreth 802 is provided with hook 801 and pressing plate 803, the hook head portions of described hook 801 is arranged in the travel path of tapered end 302, tapered end 302 and hook 801 Elastic Contact;
Microswitch 604 is articulated on base, and microswitch 604 is control circuit power switch; Described pressing plate 803 is positioned at above described microswitch 604, and the free end of described microswitch 604 is arranged in the travel path of pressing plate 803;
When balladeur train 3 moves down, depression bar 304 moves down and to contact with briquetting 5 and to suppress briquetting 5 descending, and pressing plate 803 suppressed by briquetting 5, and microswitch 604 suppressed by pressing plate 803 makes it close; After briquetting 5 puts in place, depression bar 304 continues descending elasticity and steps back by briquetting 5 top, is in below described briquetting 5 top; Described tapered end 302 oppresses the described hook 801 inhaled on brandreth 802, make the iron core of suction brandreth 802 on described electromagnet 8 close, when described suction brandreth 802 is close to the iron core touched on described electromagnet 8, described tapered end 302 is shunk back by described hook 801 top, is in below described hook 801.
As shown in Figure 4, described briquetting 5 is arranged in briquetting seat 502, briquetting seat 502 limit briquetting 5 only range line from moving up and down.Range line has multiple from the mode moved up and down, and what the present embodiment adopted is that briquetting seat 502 is provided with limit sliding chutes, and briquetting 5 is provided with spacer pin, and spacer pin moves in limit sliding chutes.
As shown in Figure 4, described tapered end 302 comprises slide 3022, has the dead bolt 3021 of lower inclined plane and spring 3023, and described slide 3022 is one end open, and the other end has the cylinder in hole; One end of described dead bolt 3021 is provided with lower inclined plane, and the other end is provided with anticreep boss; Described dead bolt 3021 is positioned at described slide 3022, and dead bolt 3021 is provided with one end of lower inclined plane through the hole on described slide 3022, and the other end contacts with spring 3023.
Depression bar 304 can adopt various ways.As shown in Fig. 4, Fig. 5, Fig. 6, described depression bar 304 is " L " type, and the upper end of depression bar is fixed on balladeur train 3, and lower end is termination 3041, and termination 3041 is double inclined plane, and inclined-plane, termination is the contact surface contacted with briquetting, and depression bar 304 has elasticity, can retreat in termination.Also can as shown in Fig. 6, Fig. 8, Fig. 9, described depression bar 304 comprises slide 3042, the bevelled slide block of tool and spring 3043, and described slide 3042 is one end open, and the other end has the cylinder in hole; The termination 3041 of described slide block is provided with double inclined plane, and the other end is provided with anticreep boss; Described slide block is positioned at described slide 3042, and the termination 3041 of slide block is through the hole on described slide 3042, and the other end contacts with spring 3043.
Described microswitch 604 arranges two.
Fig. 1, Figure 2 shows that the non-duty of toaster.Balladeur train 3 remains on above in movement 1 under the effect of stage clip 201, and switch 6 is in off-state, and microswitch 604 one end tilts and is in off-state, and toaster movement 1 is in off-position.
When user uses toaster to toast bread, toaster bread baking groove put into by bread by user, then, press down hand when to make on balladeur train 3 and balladeur train 3 fixing bracket holder bread along vertical shaft 2 slide downward 305, first the balladeur train compressing tablet 301 on balladeur train 3 pushes down switch press strip 601, along with continuing to press down hand 305, balladeur train 3 continues to move down, balladeur train compressing tablet 301 continues pressure switches press strip 601, makes switch press strip 601 rotate rocking arm 602, forces switch shrapnel 603 to close.In the process that balladeur train 3 moves down, the depression bar 304 be fixed on balladeur train 3 moves down pushes down briquetting 5, briquetting 5 is pushed down and is inhaled brandreth 802, inhale the free end that microswitch 604 tilting pushed down again by the pressing plate 803 that brandreth 802 connects, the free end that microswitch 604 is tilted is rotated down, and microswitch 604 is closed, circuit turn-on, bread baking groove energising on toaster, the iron core on described electromagnet 8 produces electromagnetic force.Simultaneously, tapered end 302 fixing on balladeur train 3 oppresses the hook 801 inhaled on brandreth 802, make the iron core of suction brandreth 802 on described electromagnet 8 close, when described suction brandreth 802 is close to the iron core contacted on described electromagnet 8, suction brandreth 802 is held, along with balladeur train 3 continues to move down, tapered end 302 continue compressing hook 801, tapered end 302 is subject to the compressing of the reaction force of hook 801, dead bolt 3021 compression press spring 3023 and after move, dead bolt 3021 is shunk back by linking up with 801 tops, is in below hook 801.The flex under action of depression bar 304 under the obstruction of briquetting 5 reaction force, on inclined-plane, depression bar termination 3041 simultaneously, as shown in Figure 5.Balladeur train 3 continues to move down, and depression bar 304 enters the groove of briquetting 5, as shown in Figure 6.When user discharges hand 305, balladeur train 3 loses the pressure moved down, move up under the effect of spring 201 elastic force, thus, briquetting 5 is no longer oppressed and is inhaled brandreth 802 and inhale the pressing plate 803 that brandreth 802 is connected, but tangled by hook 801 because tapered end 302 is in below the gib head inhaling hook 801 on brandreth 802, thus make balladeur train 3 and the bracket that balladeur train 3 is connected and bread remain on the bottom of toaster movement 1, toaster starts toast bread.
Toaster under the state of toast bread, due to inhale brandreth 802 held by the electromagnetic force of electromagnet 8 upper core, thus make the pressing plate 803 on suction brandreth 802 push down always microswitch 604 make circuit keep conducting, briquetting 5 no longer compresses suction brandreth 802.Limited post 7 is used to restriction balladeur train 3 and moves down further, brandreth 802 is inhaled to avoid pushing down, when making suction brandreth 802 iron core be without suction after electromagnet power-off, inhale brandreth 802 and can lift certain distance, the pressing plate 803 that suction brandreth 802 connects just can be made no longer to oppress microswitch 604, make the free end of microswitch 604 rotate up and disconnect, thus make whole down circuitry.
When the power-off of baked bread electromagnet 8 loses electromagnetic force, suction brandreth 802 can one end be lifted with the elastic force of microswitch 604 itself, makes microswitch 604 power-off.When after microswitch 604 power-off, even if balladeur train 3 rests on toast bread state, even if switch 6 is still connected, heating wire is also without electricity, plays the function of mechanical anti-sticking.
When the power-off of baked bread electromagnet 8 loses electromagnetic force, inhale on brandreth 802 and link up with 801 not at tight hook lock head 302, balladeur train 3 rises under the effect of spring 201 spring force, and depression bar 304 and briquetting 5 are thrown off, and can return to Fig. 1 state.
Depression bar 304 is changed into retractable movable depression bar more reliable performance, as shown in Fig. 7, Fig. 8, Fig. 9.When balladeur train 3 moves down, the termination 3041 in movable depression bar contacts with briquetting 5, and briquetting 5 is moved down.When briquetting 5 move down put in place time, termination 3041 compression press spring 3043 makes termination 3041 retrude, and as shown in Figure 8, balladeur train 3 continues to move down, termination 3041 move down into briquetting 5 groove time, termination 3041 is ejected as shown in Figure 9, briquetting 5 no longer pressurized.After electromagnet power-off, microswitch 604 is liftable makes whole down circuitry, reaches the effect of mechanical anti-sticking.
