The present invention relates to a door opening and closing device of a microwave oven, and in particular, installs a movable piece for pushing the latch under the latch latching jaw that latch is installed on the door and raises the movable piece by the operation of the cam at the handle end for door release. It relates to the configuration of the door opening and closing device of the microwave oven by opening and closing the door.

Conventionally, as shown in FIG. 1, when the door release button 30 is pressed, the lever 31 rotates about the shaft 31 'so that the movable piece 32 is lowered like the dotted line. The projection plate 34 is caught on the jaw 22, and thus the rotation plate 35, which cannot be rotated, is rotated by the elastic force of the spring 36 around the shaft 35 'like the solid line, thereby latching the latches at the latching jaw 37. 38) is released, so that the door 39 is opened and closed, but the structure is very complicated and the number of parts increases the manufacturing cost and work efficiency is reduced, as well as the force to push the door release button is transmitted through a number of levers Because of the structure, the transmission of force becomes uncertain and there is a problem that it is inconvenient to operate the door opening and closing.

The present invention is to simplify the structure of the door opening and closing part of the microwave oven to solve such a problem, to reduce the manufacturing cost and increase the work efficiency, as well as to facilitate the door opening and closing operation.

As shown in FIG. 2 (a) and FIG. 2 (b), the device of the present invention has an upper and a lower latch connected to the microwave door 1 by a spring 2 and connected by a connection 3. 4 and 5, respectively, to be latched to the latch hook (7, 8) formed in the stove body 6, the movable piece (9) to move up and down the line of the latching jaw (8 ') of the lower latch hook (8) The central long hole 10 is fitted with a projection shaft 11, the inclined jaw 12 of the upper end of the movable piece 9 abuts the end 5 ′ of the lower lever 5, and the lower end 13 of the movable piece 9. ) Is designed to slide on the outer circumferential surfaces 15 'and 15 "of the cam 15 at the end of the door release knob 14, where 16 and 17 are springs and 18 are latch shafts.

As shown in FIGS. 2A and 2B, the latching 4 and 5 of the latch hooks 7 and 8 with the latches 4 and 5 in the state in which the door 1 is closed are shown. ) And the latches 4 and 5 are prevented from being released from the latch hooks 7 and 8 by the elastic force of the spring 2 so that the door 1 remains closed.

In this case, the cam 15 at the end of the door release knob 14 has an outer circumferential surface 15 ′ corresponding to a short radius on the rotation center line, so that the lower end 13 of the movable piece 9 comes into contact with the spring 13. 16) It is in the lowered position by the elastic force.

When opening the door 1, turn the door release knob 14 in Fig. 2a, and as shown in Fig. 2b, the cam 15 at the end of the button is placed on the outer peripheral surface 15 " As the abutment comes in contact with the movable piece 9, the springs 16 and 17 are all stretched and the movable piece 9 is guided to the long hole 10 and the projection shaft 11 to linearly move.

When the movable piece 9 is raised, the lower latch 5 end 5 'is pushed up by the inclined jaw 12 at the upper end thereof so that the lower latch 5 is peeled off from the latch hook 8, and at the same time, the lower latch The upper latch (4) connected to the (5) and the connecting pipe (3) is also out of the latch hook (7), the door (1) is to be opened.

When the handle 14 is released, the cam 15 and the handle 14 are returned to the initial state by the spring 17 elastic force, and the movable piece 9 is also returned to the original state by the spring 16 elastic force. do.

When the door 1 is closed, the inclined ends 4 ", 5" of the latches 4, 5 rise up the inclined surfaces 7 ", 8" of the latch hangers 7, 8, and the spring 2 elastic force By the end, the state of FIG. 2a finally becomes, and the door 1 is closed.

Thus, according to the present invention, the door opening and closing part of the microwave oven can be simplified and the number of parts can be reduced, thereby reducing the manufacturing cost and improving the work efficiency due to the shortening of the working time, as well as miniaturization of the device.

Claims (1)
