The present invention relates to a door opening and closing device of a microwave oven, and more particularly to a door opening and closing device of a simple structure interlocking with an interlock switch (interlock switch) without a separate handle for opening the door.

In the conventional microwave oven, a separate handle is attached to open and close the door, which complicates the appearance of the microwave oven and increases external dimensions, which is disadvantageous for packaging and transportation. In addition, when there is no handle, a locking device for ensuring the door is closed and an interlocking device for opening the door are added, but this complicates the internal structure of the door frame and the main frame and causes a cost increase. There was a flaw.

In the present invention, it is conceived in view of the conventional drawbacks, a simple structure in the door frame is connected to the two door ruler and the interlock switch is configured in the main frame to detect this when opening the door in conjunction with this In addition, it is possible to simply open the door by the push button from the outside to reduce the production cost and simplify the assembly process, which will be described in more detail based on the accompanying drawings.

In a microwave oven in which the door frame 1 can be opened and closed with respect to the main body frame 2, a straight lever 6 in which the inner end is formed by pins 3, 4, 5 from the lower side in the door frame 1; ), And the anchoring intervals 9 and 10 having the leading projections 7 and 8 extend outwardly through the openings 11, 12, and 13, respectively, and the lever 6 and the interval between the anchorages. (9) (10) connects the middle of the connecting section (14) and (15) with a spring (16) to hold the middle of the connecting section (10), and within the body frame (2) between the lever (6) (9) (10) to form the opening (17) (18) (19) is inserted into the ruler interval (9) (10) is ruled by the ruler (20) (21), each ruler interval (9) 10, the front end protrusions (7) and (8) are engaged with the interlock switches (22) and (23) installed in the main body frame (2), and the pins (24) in front of the front end of the lever (6). A lever operating block (2) in which an inclined surface (26) is in contact with the front end of the lever (6) on one side by installing an operating lever (25) which is intermediately built 7) by fixing the spring back 28 to the rear, and the other side of the operating lever 25 is a structure by installing the push button 29 exposed to the outside of the main body frame (2).

The present invention is to push the push button 29 exposed to the outside in the main body frame 2 when the door is to be opened. At this time, as the actuation lever 25 extended by the pin 24 rotates in the direction of the arrow shown in FIG. 2 while extending the spring 28, the lever actuation block 27 in the opposite direction in which the push button 29 is mounted. ) Is grounded to the lever 6 extending through the opening 11 of the door frame 1 and the opening 17 of the main body frame 2, and the tip of the lever 6 is connected to the lever operating block 27. It is moved along the inclined surface 26. In accordance with the operation of the lever (6), the regular interval (9, 10) connected by the connection between the 14 (15) is moved to the same degree while extending the spring 16 to escape from each ruler (20) (21) The door is opened by the force of the lever operating block 27 while the lever 6 is opened from the interlock switches 22 and 23. In the case of closing the door of the microwave oven, while pushing the door as it is, it is pushed to the ruler (20) and (21), it is ruled on the rear side thereof and closes the interlock switch (22) (23). The door is closed.

As such, the present invention has an advantage in that the door frame and the main body frame have a simple structure and the door can be simply opened by the operation of the pushbutton having a small exposure degree without a separate handle on the door.

Claims (1)
