The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 6, the furnace chamber switch lock structure of this micro-wave oven, described micro-wave oven comprises that inside is provided with the stove seat/body 2 of locker 3, is used for the furnace chamber of cooking food, and the bonnet hinged with stove seat/body/door 1; Bonnet/door is provided with the buckling clamping part 5 that is connected with locker.Locker comprises that the carriage 7, the rotation that fixedly install are arranged on jam plate 6 and torsion spring 10 on the carriage, and the torsion spring two ends join with carriage and jam plate respectively; Jam plate is provided with and the buckling clamping part fixing dead bolt 6.1 that joins; Stove seat/body is provided with the parts 4 of unblanking that order about jam plate and buckling clamping part disengaging.The dead bolt 6.1 of jam plate is hook-shaped, and the downside of the corresponding dead bolt of jam plate extends the shifting block 6.2 of unblanking, and the upside of the shifting block of unblanking is provided with the lead-in chamfered 6.21 of locking.
Locker comprises that also rotation is arranged on unblanking on the carriage 7 and drives shifting block 8; Unblanking, it is L-shaped to drive shifting block, and the shifting block 8.1 of unblanking that the one side is provided with and the parts 4 of unblanking join, opposite side are the jam plate shifting block 8.2 that joins with jam plate 6, and the parts of unblanking drive shifting block and order about jam plate and buckling clamping part disengaging by unblanking.Unblank to drive the bottom of shifting block 8 and extend baffle plate 8.3, baffle plate and jam plate shifting block 8.2 end faces that carriage 7 is corresponding respectively unblanks to drive shifting block are provided with lower gear 7.3 and last gear 7.7.The B place of Fig. 5 and the D place of Fig. 9 are seen in the effect of upper and lower gear respectively.
Above-mentioned furnace chamber switch lock structure is mainly used in the micro-wave oven that comprises that stove seat, buckling clamping part 5 and furnace chamber constitute, and bonnet is hinged on stove seat top by hinge 12 (see figure 7)s, and bonnet and stove seat surround furnace chamber jointly.Buckling clamping part 5 is arranged on the bottom surface of bonnet; The corresponding buckling clamping part 5 of stove seat end face is provided with porose position; When closing bonnet downwards, buckling clamping part is fixedlyed connected with locker 3 in the stove seat is inserted in the position, hole.
Its operation principle is: when bonnet/when door 1 is closed, buckling clamping part 5 passes the through hole 7.6 of carriage 7 and fastens with the dead bolt 6.1 of jam plate 6, and the shifting block of unblanking of jam plate is resisted against on the drive block of unblanking; The switch contact block 6.3 of dead bolt is pushed down the shift knob 11.1 of microswitch 11 simultaneously, makes the operating circuit of micro-wave oven inside be in conducting state, sees Fig. 1-Fig. 6.When needs are opened bonnet/door, pull the parts 4 of unblanking on the micro-wave oven, rotate up thereby drive the drive block of unblanking, the drive block of unblanking drives jam plate and upward deflects, and simultaneously, snap switch contact block and the shift knob of jam plate deflection stagger, the inner disconnection of microswitch; In addition, when jam plate deflection surpasses the critical value of torsion spring 10 compressions, continue automatically to upward deflect to breaking away from fully with buckling clamping part 5; Simultaneously, owing to connect the active force of the hinge 12 of stove seat/body 2 and bonnet/door 1, bonnet/door automatically springed open certain angle when buckling clamping part and jam plate broke away from, and saw Fig. 7-Figure 10.In addition, because the particularity of microwave oven shown in the figure, it is when cooking food, having certain water vapour in the furnace chamber contacts with the bonnet inwall, after the water vapour condensation along sliding to furnace chamber bottom (both stove seat tops) under the profile of bonnet, condensed water just probably enters on the jam plate from the buckling clamping part patchhole at stove seat top, but because jam plate and microswitch are positioned on the different faces (specifically be by carriage main panel separate), so condensed water can not impact microswitch.
On the micro-wave oven that above-mentioned furnace chamber switch lock structure also can be applicable to be made of body of heater, furnace chamber and fire door; Furnace chamber is arranged in body of heater, and the one side is opened wide; Fire door is hinged on furnace chamber by hinge and opens wide the place.Buckling clamping part 5 is arranged on the inboard of fire door; The positive corresponding buckling clamping part of body of heater is provided with porose position; When closing fire door, buckling clamping part is fixedlyed connected with locker 3 in body of heater is inserted in the position, hole.
