The specific embodiment
Embodiment of the present utility model is intended to design a kind of interlock of opening the door, can be general on sliding door type and 2 kinds of modes of opening the door of button.
Fig. 3 illustrates the versatible furnace gate interlock mechanism exploded view of the utility model one embodiment.With reference to shown in Figure 3, sliding door type and the general interlocking mechanism of button opening door comprise gate stop 31, switch base 32, header board 33 these 3 universal components.In these parts, header board 33 is used for fixing on the cavity of microwave oven 30 (with reference to Fig. 2).Switch base 32 is used for fixing a plurality of switches of interlock, for example short switch 32a, primary switch 32b and secondary switch 32c.Certainly, number of switches of the present utility model can increase or reduce not as limit according to microwave oven structure.
In addition, general interlocking mechanism also comprises the exclusive parts lever 34 that opens the door, as the special use of button door-opening mechanism.The lever 34 that opens the door is installed to switch base 32 by single-revolution axle 34a, and can be by this gyroaxis 34a around switch base 32 rotations.
Compare known fire door interlocking mechanism, present embodiment has been cancelled spacer block and first lever, second lever, has reduced the parts usage quantity.Fig. 4 illustrates the assembled state figure of versatible furnace gate interlock mechanism of the utility model one embodiment.With reference to shown in Figure 4, gate stop 31, switch base 32 and header board 33 and the lever 34 that optionally opens the door are assembled on the cavity 30.
Fig. 5 illustrates the door opening state figure of versatible furnace gate interlock mechanism of the utility model one embodiment.With reference to shown in Figure 5, switch base 32 is provided with the first action key 32d in the position of corresponding short switch 32a, and the position of corresponding primary switch 32b is provided with the second action key 32e, and the position of corresponding secondary switch 2c is provided with the 3rd action key 32f.Fig. 7 illustrates the circuit diagram under the state shown in Figure 5.With reference to Fig. 5 and shown in Figure 7, under the door opening state, all not by arbitrary hook portion touching of gate stop 31, primary switch 32b, secondary switch 32c disconnect at this moment, short switch 32a closure for the first action key 32d, the second action key 32e and the 3rd action key 32f.
The versatible furnace gate interlock mechanism that Fig. 6 the illustrates the utility model one embodiment state diagram of closing the door.Fig. 8 illustrates the circuit diagram under this state.With reference to Fig. 6 and shown in Figure 8, following action takes place at closing time successively, the first action key 32d is touched by the first hook portion 31a of gate stop 31, short switch 32a disconnects, then, the second action key 32e is by the first hook portion 31a of gate stop 31 touching, and the 3rd action key 32f is by the second hook portion 31b of gate stop 31 touching, primary switch 32b and secondary switch 32c closure.
Under the state of closing the door shown in Figure 6, when using sliding door power F1 to act on gate stop 31, perhaps use pressing force F2 to act on when opening the door lever 34, fire door is opened.
In preferred embodiment, and when no matter opening or closing, all keep the regular hour poor between the action of the action of short switch and primary/secondary switch, produce to prevent short circuit current.
Short switch and primary/secondary difference switch time produce an example of structure with reference to shown in Fig. 9 A-9D.At first with reference to Fig. 9 A, 9B is in the process of closing the door, and gate stop 31 is at first touched the first action key 32d, thereby triggers short switch 32a, and gate stop 31 is not touched the second action key 32e and the 3rd action key 32f, thereby does not trigger primary switch 32b and secondary switch 32c.With reference to Fig. 9 C, 9D, close the door when finishing then, the second action key 32e and the 3rd action key 32f are also touched, thereby elementary, secondary switch 32b, 32c and short switch 32a all move.
Fig. 9 A-9D is depicted as the process of closing the door, and the process of opening the door is then opposite, promptly elementary, secondary switch 32b, 32c action earlier, short switch 32a action then.
Thus, the foregoing description is by opening the mutual motion of gate stop 31 and switch base 32 at closing time, and control short switch, primary switch, secondary switch sequence of movement play the function of control and monitoring microwave oven electronic loop.
In sum, the embodiment of the described general interlocking mechanism of the utility model has solved the problem that the interlocking mechanism of 2 kinds of modes of opening the door can not be general originally, and has reduced number of components.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
