Description

APPARATUS TO ASSEMBLE AN EXTERJNLO PANEL.FOR MICROWAVE OVEN, A N T EC E D N E S T H E N I NVEN C Y N S FIELD OF THE INVENTION The present invention relates to an apparatus for assembling an external panel for an oven microwaves, and more particularly, with the apparatus for assembling the outer panel for a microwave oven whose attractive external appearance is seen from a front view for a microwave oven is given through a horizontal alignment an upper end and a panel External M and the upper end of the door when the door closes against the outer panel.

DESCRIPTION OF THE PREVIOUS TECHNIQUE 0 Vn a conventional microwave oven, as illustrated in Figures 1 and 2, a cooking chamber 60 of a constant space prepared for cooking food therein, and having a cavity 10, a front panel 20, a rear panel 30 and an outer panel 50. The microwave oven also has a turntable 70 placed on the floor of the cooking chamber 60. The turntable 70 is used to rotate the food (eg, an object to be cooked by heat). ) placed on the turntable 0. Further, the microwave oven has a door 80 provided for opening and closing the cooking chamber 60 and a control unit 90 provided for setting the types of cooking function or for operating a magnetron (not shown). ), and other components. The flanges 21 horizontally extended in relation to the plane of the front panel 30 is provided in the rear part of the upper portion of the front panel 30. A bent portion 51, in the form of "S" in a sectional area thereof is provided in FIG. a front end of the outer panel 50, such that the flange 21 is pressed into the portion 51, in an "S" shape, of the front area of the outer panel 40 to be engaged in one another. In order to activate the microwave oven mentioned in the above, a user opens the door 80 to place the food on the turntable 70 and then closes the door 80. Subsequently, when a user sets the type of cooking function in the unit of control 90, the turntable, to which electric power is supplied, begins to rotate in one direction at a microwave energy of 2.45 GHz generated by a magnetron (not shown). The generated microwaves are radiated to the food on the turntable through a waveguide (not shown), where the conversion of heat energy into the food as a dielectric material is caused by the microwave energy. However, it is seen that when the front panel 20 and the outer panel 50 are coupled to one another by means of the respective flange 21 and the "S" shaped portion 51, part of the "51" shaped portion "projects outwardly with respect to the front panel 20 as shown in Figure 2. In the event that a front opening of the front panel 20 is closed by a door 80, such a projection formed causes a certain space A to be formed between a upper end of the door 80, when closed, and an upper end of the outer panel 50. This space A affects an attractive external appearance of the microwave oven.

BRIEF DESCRIPTION OF THE INVENTION Therefore, it is an object of the present invention to provide an outer panel assembly apparatus for a microwave oven whose attractive external appearance as seen from the front view of a microwave oven is given through a horizontal alignment between the upper end and the outer panel and the upper end of a door when the door is closed against the outer panel. To achieve the above objectives, an assembly apparatus for the outer panel adapted to attach an upper end of a front panel and a front end to an outer panel is provided, characterized in that when viewed from the front view of a microwave oven, the upper end of a front panel and the front end of an outer panel are coupled by means of projection and slot, such that an upper end of the door and an upper end of the outer panel are aligned.

BRIEF DESCRIPTION OF THE APPENDIX DRAWINGS Figure 1 is a front perspective view of a microwave oven according to the prior art; Fig. 2 is a partial sectional view of a door and an external panel, according to the prior art, when these components are coupled, with the space A formed between the door and the outer panel; and Figure 3 is a partial sectional view of a door and the outer panel with no space between the door and the outer panel when coupled.

DETAILED DESCRIPTION OF THE MODALITY The preferred embodiment of the present invention will be described with reference to the accompanying drawings. In all the drawings similar reference numbers are used for the designation of similar portions. As shown in FIG. 3, an external panel assembly apparatus, according to the present invention, includes a front panel 20 and an outer panel 50: the front panel 20 is provided at an upper end thereof with a bent portion. rearwardly horizontally 21 in relation to the plane of the front panel 20, the portion 21 also has a projection 22 inclined upward at its front end portion and formed by a cutting process; and the outer panel 50 is provided at an upper end thereof with a portion 52 facing down and then bent inward in a U-turn in a sectional view, this portion 52 also has a slot 53 through which the projection 22 it is inserted to be hung so that the front panel 20 and the outer panel 50 can be coupled to one another. It is noted that the external plane of the front panel 20 is vertically aligned with the front end of the outer panel 50.

Next, the operation and effect of the present invention will be described below. The front panel 20 with the folded portion 21 facing rearwards is coupled to a front side of the cavity 10. Then, on an upper surface of the portion 21 sits on the folded portion 52 of the outer panel 50, where the projection 22 and slot 53 engage one in the other. In other words, the projection 22 formed in the bent portion 21 of the front panel 20 is inserted into the groove 53 formed in the bent portion 52 of the outer panel 50 and then the outer panel 50 is moved horizontally in a backward direction. This action allows the projection 22 to be hung in the slot 22, resulting in a vertical alignment with respect to the front ends of the front panel 20 and the outer panel 50. Accordingly, when the door 80 is closed, the door 80 does not impact with the front end of the outer flange 50. With the closed purge, the external appearance of the product provides a horizontal alignment between the upper end of the door 80 and the upper end of the outer panel 50, which makes the appearance attractive.
