As shown in FIGS. 1 to 3, a cooking chamber 7 to which microwaves are irradiated is provided inside the case part 5 of the microwave oven 1.

The door member 3 is provided on the front surface of the cooking chamber 7 (the left side of FIG. 1), and the door member 3 opens and closes the cooking chamber 7 by the operation of the opening / closing device 50 for a microwave oven.

Microwave oven opening and closing device 50 according to an embodiment, the handle portion 10 is formed to protrude to the outside of the door member 3, the first locking portion 20 that is rotated by the operation of the handle portion (10) And a second catching portion 30 spaced apart from the first catching portion 20, and a link portion 40 hinged to the first catching portion 20 and the second catching portion 30, respectively.

Handle portion 10 is formed to protrude to the outside of the door member 3 (hereinafter referred to as reference 1 Fig. 1) can be formed in a variety of shapes, including the "b" shape.

The handle portion 10 includes a holding member 12 which is held by a user and a bending member 14 that is bent from the holding member 12 and coupled to the first locking portion 20.

As the user grips and lifts the handle part 10, the handle part 10 rotates in a clockwise direction (hereinafter, referring to FIG. 1).

The first locking portion 20 is connected to the handle portion 10 and the rotation operation is performed, one side (left side of FIG. 1) is connected to the handle portion 10 with a hinge portion connected to the door member 3. The other side (right side of FIG. 1) is formed to protrude to the inside of the door member 3.

The first catching part 20 may be formed in various shapes within the technical concept in which the rotating part is connected to the handle part 10.

The first locking portion 20 according to an embodiment, the first body is hinged to one side of the door member 3 and the other side is extended to the inside of the door member 3 is provided with a first locking ring 24 The first connecting member 28 is bent from the member 22 and the first body member 22 and connected to the handle part 10.

Since one side of the first body member 22 is hinged to the door member 3 by the first rotation shaft 26, the first catching portion 20 is rotated about the first rotation shaft 26.

The first locking projection provided in the first body member 22 is attached to and detached from the groove portion provided in the case portion 5 by the rotation operation.

The second locking portion 30, which is spaced apart from the first locking portion 20 and hinged to the door member 3, has one side hingedly connected to the door member 3, and the other side extends inside the door member 3. And a second body member 32 having a second catching ring 34.

Since one side of the second body member 32 is hinged to the door member 3 by the second rotation shaft 36, the second catching portion 30 is rotated about the second rotation shaft 36.

The second locking projection provided in the second body member 32 is attached to and detached from the groove portion provided in the case portion 5 by the rotation operation.

The link portions 40 hinged to the first catching portion 20 and the second catching portion 30 are formed in a bar shape. The link unit 40 is hinged to the first body member 22 by the first connecting shaft 42 and hinged to the second body member 32 by the second connecting shaft 44.

Hereinafter, with reference to the accompanying drawings will be described in detail the operating state of the opening and closing device for a microwave oven 50 according to an embodiment of the present invention.

As shown in FIG. 1, in a state where the first catching part 20 and the second catching part 30 are caught inside the case part 5, the handle part 10 is installed in the longitudinal direction.

As illustrated in FIG. 2, when the user grips and lifts the handle part 10, the first connecting member 28 of the first catching part 20 connected to the handle part 10 is the first rotating shaft ( 26) is rotated about.

Since the first body member 22 having the first catching ring 24 is also rotated about the first rotating shaft 26 by the rotation of the first connecting member 28, the first catching ring 24 is the case part. Departure from (5).

The rotation of the first catching part 20 is transmitted to the second catching part 30 through the link part 40, and the second catching part 30 is also rotated about the second rotating shaft 36.

Since the second body member 32 having the second locking ring 34 is also rotated about the second rotation shaft 36, the second locking ring 34 is also separated from the case part 5.

That is, since the first locking portion 20 and the second locking portion 30 are operated at the same time by the operation of the handle portion 10, the operation is detached or fastened from the case portion 5, so that the door member 3 Opening and closing operation can be made more stable.

According to the configuration as described above, according to the operation of the microwave oven opening and closing device 50 according to the embodiment, the first locking portion 20 and the second locking portion 30 is operated simultaneously. Since it is caught by the case portion 5, the door member 3 is stably coupled to the case portion 5 can improve the operation reliability of the door member (3).

In addition, since the door member 3 is stably coupled to the case part 5, it is possible to reduce the noise generated by the door member 3 hitting the case part 5.
