[specific embodiment]

See also Fig. 1 a, 1b, 1c to Fig. 4 a, 4b, the utility model automatic toaster comprises electric control system, elevating mechanism and filter structure.Electric control system comprises switch (flexure strip 22, stator 25, contact 23-24), electromagnet (iron core 4, coil 5, coil rack 6, armature 7, armature hook 8) and the relay 2 etc. that are placed on the printed substrate 3, armature hook 8 and armature 7 are hinged on the coil rack 6, and can 6.2 be that axle rotates, and coil rack 6 is fixed on the printed substrate 3 by 4 solder joints 6.1; Elevating mechanism comprises main carriage 11 and connected armature depression bar 12 and switch briquetting 16, secondary balladeur train 10, big elastic component 21, little elastic component 13, guide pin bushing 14, vertical shaft 15 and carriage 26, main carriage 11 had both linked at vertical shaft 15 with secondary balladeur train 10 also can move and be subjected to the control of little elastic component 13 mutually, carriage 26 and L elastic component 9 are rigidly connected with secondary balladeur train 10, and main carriage 11, secondary balladeur train 10 and carriage 26, big elastic component 21, little elastic component 13, guide pin bushing 14 are set on the vertical shaft 15 and also can be free to slide on it again; The filter structure comprises filter 20, U elastic component 17, L elastic component 9, and filter 20 can 27 be that the stopper slot 18 of the center of circle on movement rotates, and the elastic force of U elastic component 17 makes filter 20 be in normal open position.

Its operation principle is:

1. work: when main carriage drives secondary balladeur train and the opposed glides downward of carriage by little elastic component, connection power supply, electromagnet get electric, and the armature hook pins main carriage, secondary balladeur train and carriage, simultaneously, the L elastic component presses the bread filter and steps up bread, begins bread is toasted;

2. discharge: when the stoving time end that sets, the electromagnet dead electricity, main carriage, secondary balladeur train, carriage are together with baking good bread under the elastic force effect of big elastic component, beginning also turns back to original state, simultaneously, and the switch outage, the bread filter is got back to the enable possition under the effect of U elastic component;

3. promote: for the less bread of size, can use enhanced feature, promote promptly that main carriage drives secondary balladeur train and carriage slides together with opposed axially the going up of roasting good bread.

4. safeguard protection: when the stoving time that sets finishes, block secondary balladeur train and carriage together with roasting good bread in case bread occurs, the electromagnet dead electricity, along the vertical shaft segment distance that upwards slides, the switch outage avoids bread to catch fire to main carriage by little elastic component.

As figure Fig. 1 a, 1b, 1c, when original state, the carriage 26 of the main carriage 11 of elevating mechanism, secondary balladeur train 10 and carrying bread is in tip position, and filter 20 is in vertical position, and switch

contact

23,24 is in a fully open position.

As Fig. 2 a, 2b, when bread to be baked is put into carriage 26 and is pressed main carriage 11, the carriage 26 of secondary balladeur train 10 and carrying bread is under the elastic force effect of little elastic component 13, follow main carriage 11 on vertical shaft 15 to lower slider, when L elastic component 9 is depressed into filter 20 bottoms 27, filter 20 closes up and steps up bread, and the carriage 26 of secondary balladeur train 10 and carrying bread is with stop motion; And main carriage 11 and armature depression bar 12 and switch briquetting 16 continue to move down, little elastic component 13 is compressed, until the contact 23 of switch flexure strip 22, the contact 24 complete closures of stator 25, and coil 5 electric, iron core 4 holds armature 7, armature hook 8 tangles armature depression bar 12, make the carriage 26 of main carriage 11, secondary balladeur train II10 and carrying bread remain on vertical shaft 15 bottom positions, automatic toaster is started working.

When the stoving time that sets finishes, coil 5 dead electricity, iron core 4 discharges armature 7, armature hook 8 discharges armature depression bar 12, main carriage 11 and armature depression bar 12 and switch briquetting 16, the carriage 26 of secondary balladeur train 10 and carrying bread upwards rises at the effect lower edge vertical shaft 15 of big elastic component 21, the L elastic component breaks away from filter bottom 27, filter 20 is opened under the elastic force effect of U elastic component 17, the contact 23 of switch flexure strip 22, open fully the contact 24 of stator 25, power supply is short, when main carriage 11 and armature depression bar 12 and switch briquetting 16, when rising to tip position, automatic toaster quits work the carriage 26 of secondary balladeur train 0 and carrying bread at the effect lower edge vertical shaft 15 of big elastic component 21.

As Fig. 3 a, 3b, for the less bread of size, for avoiding hot, can use enhanced feature, promptly promote main carriage 11 secondary balladeur trains 10 of drive and carriage 26 together with the opposed axially upward slip of roasting good bread, little elastic component 13 is compressed, until reaching the extreme higher position, top, make things convenient for bread to take out.

Shown in figure Fig. 4 a, 4b, when the stoving time that sets finishes, block secondary balladeur train 10 and carriage 26 together with roasting good bread in case bread occurs, because main carriage 11 and armature depression bar 12 and switch briquetting 16 are under the effect of little elastic component 13 elastic force, still along vertical shaft 15 segment distance that upwards slides, coil 5 dead electricity, iron core 4 discharges armature 7, armature hook 8 discharges armature depression bar 12, the contact 23 of switch flexure strip 22, the contact 24 of stator 25 are opened fully, the switch outage, automatic toaster termination work avoids bread to catch fire.
