Description

Case assembly structure of the microwave oven

The present invention relates to a case assembly structure of the microwave oven, and more particularly, to a case assembly structure of the microwave oven that can reduce the assembly time by combining the outer case on the upper side of the cooking chamber assembly.

In general, a microwave oven is a device that cooks food by uniformly heating food using a high frequency oscillated from a magnetron. Such a general microwave oven is illustrated in FIGS. 1 and 2.

1 and 2, such a general microwave oven has a control panel 11 for selecting cooking conditions on one side of the front surface of the main body 10, and a cooking chamber in which food is added and cooked inside. 12 is provided, the door 13 is coupled to the front side of the cooking chamber 12 so that it can be opened and closed.

One side of the cooking chamber 12 is equipped with a magnetron 15 for radiating high frequency through the waveguide 14, and an opening for uniformly radiating high frequency into the cooking chamber 12 at the tip of the waveguide 14. 16) is formed.

On the other hand, the inside of the cooking chamber 12 is provided with a tray 19 is rotated in accordance with the operation of the drive motor 17, the lower side of the tray 18, the roller assembly for supporting the stable rotation of the tray 19 18 is arrange | positioned.

In the conventional microwave oven configured as described above, the food 13 to be cooked is placed on the upper side of the cooking tray 19 with the door 13 open, and then the door 13 is closed and the control panel 11 is closed. Selecting a cooking condition, such as a type of cooking or a time, causes the magnetron 15 to be driven by a separate control unit.

The high frequency oscillated by the driving of the magnetron 15 is uniformly radiated throughout the inside of the cooking chamber 12 through the waveguide 14 and the opening 16 to cook food.

At this time, the food is placed on the cooking tray 19 is continuously rotated by the rotation operation of the tray 19 is rotated in accordance with the operation of the drive motor 17, the high frequency radiated to the food is uniform, the entire food Uniform heating is achieved over.

3 illustrates a case assembly structure of the conventional microwave oven, and according to this case, the case assembly structure of the conventional microwave oven is assembled with the outer case 31 facing from the rear side to the front side of the cooking chamber assembly 30. After that, the outer case 31 is configured to be fastened to the cooking chamber assembly 30 using fastening means such as a bolt.

However, such a case assembly structure of the conventional microwave oven, when it is necessary to separate the outer case 31 from the cooking chamber assembly 30, such as during maintenance, a plurality of fastening on the back side of the cooking chamber assembly 30. The means was disassembled and the outer case 31 was separated from the front side of the cooking chamber assembly 30 toward the back side.

Such a work was not possible in a narrow space. Therefore, the external case 31 must be removed after the microwave oven is moved to a large space, which is very inconvenient, and the work space is separated by separating the outer case to the rear side. In addition, there are various problems such as a lot of work time is required by separating and fastening a plurality of fastening means.

Therefore, the present invention is designed to solve the above-mentioned problems of the prior art, and an object of the present invention is to allow the outer case to be assembled on the upper side of the cooking chamber assembly, thereby shortening the assembly time and simultaneously removing and assembling the outer case. It is to provide a case assembly structure of a convenient microwave oven.

51, 52: side plate 51a, 52a: insertion part

The case assembly structure of the microwave oven according to the present invention for achieving the above object, both sides of the cooking chamber assembly having a flange formed bent on the front and back plate, the insertion portion is inserted into the flange to be coupled from the upper side to the lower side of the cooking chamber assembly And an outer case formed on the plate.

Therefore, according to the present invention, as the outer case is coupled from the upper side of the cooking chamber assembly, the outer case can be separated and assembled even in a narrow space, so that the work is very convenient, and the flange of the outer case is inserted into the insert of the cooking chamber assembly. Assembly is complete, which significantly shortens the assembly time.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

4 is an exploded perspective view illustrating a case assembly structure of the microwave oven according to the present invention, and reference numeral 40 denotes a cooking chamber assembly in which a cooking chamber 41 is formed inside.

In addition, the cooking chamber assembly 40 is provided with a front plate 42 and a rear plate 43 on the front and rear sides, respectively, and the flanges 44 (both sides of the front and rear plates 42 and 43) ( 45 are each bent.

The flanges 44 and 45 are formed with a plurality of emboss portions 44a and 45a.

On the other hand, the outer case 50 is coupled to the upper side of the cooking chamber assembly 40, side plates 51 and 52 are bent on both sides of the outer case 50.

Inserting portions 51a and 52a through which flanges 44 and 45 are inserted are formed inside the side plates 51 and 52, and the inserting portions 51a and 52a are shown in FIG. As shown, it has an elastic force so that the flanges 44 and 45 inserted inward can be tightly fixed.

The case assembly structure of the microwave oven according to the present invention configured as described above assembles the outer case 50 on the upper side of the cooking chamber assembly 40 from the upper side to the lower side.

That is, when the insertion parts 51a and 52a formed in the inner side surfaces 51 and 52 of the outer case 50 are positioned above the flanges 44 and 45 and inserted downward, the outer case ( 50) assembly is completed.

In this case, as the plurality of emboss portions 44a and 45a are formed in the flanges 44 and 45, the flanges 44 and 45 are inserted into the inserting portions 51a and 52a and maintained in close contact with each other. Will be prevented.

As the inserting portions 51a and 52a have a predetermined elasticity, the flanges 44 and 45 inserted inwardly are more firmly fixed.

And, since the combination of the cooking chamber assembly 40 and the outer case 50 is made without employing a separate fastening means, it is possible to further shorten the assembly time.

As described above, according to the present invention, as the outer case is coupled from the upper side of the cooking chamber assembly, the outer case can be separated and assembled even in a narrow space, and thus the work is very convenient, and the flange of the outer case is inserted into the insert of the cooking chamber assembly. By assembling is completed, there are various effects such as significantly shortening the separation and assembly time of the outer case.

Although specific embodiments of the present invention are illustrated and described above, the present invention is not limited to the above-described embodiments, and the technical field to which the present invention pertains without departing from the spirit of the present invention as claimed in the claims. Anyone of ordinary skill in the art of various modifications can be made, as well as such changes are within the scope of the claims.
