Description

Microwave Power Cords

The present invention relates to a power source for a microwave oven coupled to a rectangular cutting groove opened from one side edge of a casing, and more particularly, to a microwave oven having a fixed body accommodating and coupled to the cutting groove to facilitate assembly. It is related to the power cord.

4 is an exploded perspective view of a microwave oven equipped with a conventional microwave power cord, and FIG. 5 is an enlarged perspective view of the microwave power cord of FIG. 4. As shown in these figures, the microwave oven includes an outer casing 101 having an inverted " U " shape for forming an appearance, and an inner casing 103 for forming a cooking cavity 105 and a component chamber 107. Have The inner casing 103 has a front plate 111, a back plate 113, and a bottom plate 115 which are respectively coupled to the front, rear, and bottom surfaces of the outer casing 101, and these front plate 111 and the back plate. It is coupled to the 113 and the bottom plate 115 and has a cavity casing 117 to form a cavity 105 therein. The cavity casing 117 has a rectangular cylindrical shape to form a cooking space, and is installed to be interposed between the front plate 111 and the rear plate 113. The bottom surface of the cavity casing 117 is provided with a tray 119 for receiving and supporting food to be cooked.

The front plate 111 is provided with an entrance opening for access of food to be cooked, and the door 106 is hinged to the left edge of the entrance opening so as to open and close the entrance opening. In addition, an opening of a component chamber 107 in which a magnetron 120 or the like for outputting microwaves is formed is formed in the cavity 105, and a plurality of operation buttons 110 are provided in the opening to select a function. Control panel 108 is coupled.

Meanwhile, a rectangular cutout groove 122 cut from the upper edge is formed in the upper portion of the component chamber side of the backplate 113 which is installed to face the front plate 111, and the cutout groove 122 is formed from the outside. Power cord for power supply is accommodatingly coupled. The outer side of the power cord is integrally formed with a fixed holder 125 that is coupled to the cutting groove 122, the both sides of the fixed holder 125 from the surface to accommodate the both edges of the cutting groove 122 A pair of recessed grooves 126 are formed to be parallel to each other.

However, in such a conventional microwave power cord, the bleed groove is formed only at both edges of the power cord fixing holder facing each other. In order to insert the fixing holder into the cutout groove, the operator grasps the holding holder to change the direction of the cutting groove. Therefore, there is an inconvenience in that the direction of the fixed holder must be adjusted.

Accordingly, it is an object of the present invention to provide a microwave power cord that can facilitate assembly.

The object of the present invention is a microwave power cord coupled to a rectangular cutting groove opened from one side edge of a casing, the square fixture being accommodated in the cutting groove and the fixing body interposed therebetween. It is achieved by a microwave oven power cord, characterized in that it comprises a fixing holder having a pair of flanges disposed to face each other and in contact with the inner surface and the outer surface of the casing.

Here, the fixing body is preferably formed integrally with the power cord.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention. 1 is an exploded perspective view of a microwave oven equipped with a microwave power cord according to the present invention, Figure 2 is a cutaway perspective view of a microwave power cord according to the present invention, Figure 3 is a microwave power cord of Figure 2 Side view. As shown in these figures, the microwave oven includes an outer casing 1 having an inverted “U” shape for forming an appearance, and an inner casing 3 for forming a cooking cavity 5 and a component chamber 7. Have The inner casing 3 has a front plate 11, a back plate 13, and a bottom plate 15 which are respectively coupled to the front, rear and bottom surfaces of the outer casing 1, and these front plates 11 and the back plate. And a cavity casing 17 which is coupled to the bottom plate 15 and the bottom plate 15, respectively, and forms a cavity 5 therein. The cavity casing 17 has a rectangular cylindrical shape to form a cooking space so as to be interposed between the front plate 11 and the rear plate 13. The bottom surface of the cavity casing 17 is provided with a tray 19 for receiving and supporting food to be cooked.

The front plate 11 is formed with an access opening for access to the food to be cooked, the left edge of the access opening is coupled to the door (6) hinged to the upper and lower ends of the front plate (11). In addition, an opening of a component chamber 7 in which a magnetron 20 and the like for outputting microwaves is formed in the cavity 5 is formed in the right region, and the opening is provided with a plurality of operation buttons 10 for function selection. Control panel 8 is coupled.

On the other hand, in the upper region of the component chamber side of the rear plate 13, a rectangular cutout groove 22 cut out from the upper edge is formed, and the cutout groove 22 has a fixing holder for a power cord for supplying power from an external source. (25) is combined. The fixed holder 25 includes a pair of inner flanges 29 and an outer flange 31 which are arranged to face each other with a square fixture 27 and a fixture 27 interposed therebetween. Have The fixed body 27 extends horizontally in the axial direction on the outer side of the covering of the power cord, and has a square shape slightly smaller than the width of the cutting groove 22 to be accommodated in the cutting groove 22 in consideration of assembling property. It is formed.

In addition, the outer flange 31 and the inner flange 29 are disposed to face each other at both ends of the fixture 27 along the axial direction of the power cord, so that the fixture 27 is cut off by the force or impact in the axial direction. Arbitrary detachment from the groove 22 is prevented. That is, the inner flange 29 is in contact with the inner surface of the rear plate 13 to correspond to the tensile force to pull the power cord outward, the outer flange 31 when the force is applied inward along the axial direction of the power cord The fixing body 27 is prevented from being separated from the cutting groove 22. In consideration of this point, the inner flange 29 and the outer flange 31 are formed to be sufficiently larger than the width of the cutting groove 22.

By such a configuration, when the power cord is lowered from the upper side of the cutting groove 22 so that the edge of the cutting groove 22 is accommodated between the flanges 29 and 31 of the power cord, the fixing body 27 cuts the cutting groove 22. Are simply accepted. At this time, unlike the conventional power cord for microwave oven, the fixing body 27 is formed in a square, there is no inconvenience to turn the fixing holder 25 to match the bite groove to the cutting groove 22.

Thus, by forming a pair of flanges which are disposed opposite to each other at both ends of the square fixture and the fixed body coupled to the cutting groove cut from one side edge in the casing to prevent the axial deviation of the fixed body, The fixing holder can be easily inserted into the cutout groove.

In the above description and the embodiment, the flange is configured in the same manner as the fixed body and described, but the shape of the flange, such as a circle or an arbitrary polygon, can be variously configured.

In addition, although the fixing body is described as being integrally formed with the covering of the power cord, a passage hole may be formed so that the power cord can pass along the axis of the fixing body.

As described above, according to the present invention, there is provided a power cord for a microwave oven that can facilitate assembly.
