Description

Microwave Oven with corner reinforced

The present invention relates to a microwave oven, and more particularly, to a microwave oven having a corner reinforcement structure corresponding to the impact generated during transportation of a manufactured microwave oven.

In general, a microwave oven (MWO) is a device for cooking food by the heat of intermolecular friction generated by disturbing the molecular arrangement of food by using a high frequency (about 2,450 MHz per second) as a heating source.

1 is a perspective view showing the appearance of a conventional general microwave oven.

Referring to FIG. 1, the microwave oven generally includes a main body 10 including a front case 11 and an outer case 12, an exterior frame 13, a cavity 20 forming a cooking chamber, and It is configured to include an electric equipment room 30 in which various electric equipment parts are installed.

In this case, the front case 11 forms the front surface of the main body 10, and is provided with a cavity door 14 for opening and closing the cavity 20.

In addition, the exterior frame 13 forms the bottom and the rear of the main body 10 and together with the outer case 12 and the front case 11 to protect the cavity 20 and the electric compartment 30 from an external environment. do.

The electrical component is a magnetron 31 that generates microwaves, a high voltage transformer 32 that supplies a high voltage to the magnetron 31, and various electrical components inside the body 10. It is comprised including the blowing fan 33.

The microwave oven having such a configuration is packaged after manufacture is completed, and is then transported to each microwave oven store, and then, again to the home or business.

At this time, it is common practice to transfer the shock absorber of styrofoam to the outside of the microwave oven in order to protect the microwave oven from the shock caused by the carelessness of the operator during the transportation of the microwave oven.

2 is a schematic perspective view showing a form in which the shock absorber 2 surrounds the microwave oven.

The shock absorbing material 2 does not protect the entire surface of the microwave oven, but mainly surrounds the microwave oven to protect corners and edges of the microwave oven.

However, even in a microwave oven wrapped by the shock absorber 2, when the rear end edge falls to hit the ground, the weight of the microwave concentrates on the corners and the impact amount increases, so that the shock absorber 2 absorbs all the shocks. As shown in FIG. 3, the corner outcase 12 is distorted.

In particular, the microwave oven provided by the set of the gas oven range of the recent microwave oven has a problem that the weight is considerable, the distortion is more severe during the above-described corner impact.

The present invention has been made in order to solve the problems of the prior art described above, by providing a structure for preventing the damage to the corners of the microwave oven due to an unexpected impact or drop during transportation of the manufactured microwave oven to the consumer It is an object of the present invention to provide a microwave oven with a corner portion capable of minimizing product defects by the time the microwave oven reaches completion.

2: shock absorber 21: vent grill

23: suction filter 25: front case

26: Outcase 30: Chamfer

31: chamfer edge

In order to achieve the above object, the present invention forms an approximately rectangular parallelepiped, and includes a front case, an outer case, a cavity, and a base plate forming the exterior, wherein a chamfer is formed at an edge of the microwave oven. It is characterized by providing a microwave oven with a reinforced edge portion.

In particular, the chamfer is characterized in that the angle between the chamfer edge portion and the outer edge portion extension line of the microwave oven is formed in the range of 30 to 60.

The present invention will be described in more detail with reference to the accompanying drawings with respect to the configuration of the microwave oven is reinforced. For reference, prior to describing the configuration of the present invention, in order to avoid duplication of description of the prior art reference to the same reference numerals will be referred to.

Figure 4 is a perspective view showing a preferred embodiment of the microwave oven is reinforced corner portion according to the present invention.

The microwave oven according to the embodiment is an OTR (Over The Range) microwave oven, and a vent grill 21 for sucking and discharging outside air is formed above the front part of the microwave oven, and a suction filter 23 (see FIG. 5) is provided on the bottom of the microwave oven. Is equipped.

The microwave oven is usually designed to be installed on the upper side of the gas oven range so that the smell and smoke cooked in the gas oven range are sucked into the suction filter and then discharged to the outside.

The present invention is not only applicable to the OTR microwave oven of the above-described embodiment, but is applicable to all microwave ovens.

5 is an exploded perspective view schematically showing the microwave oven of the embodiment. When the external configuration of the microwave oven of the above embodiment is schematically described, the front case including the door (see FIG. 4), the base plate 28 constituting the bottom of the microwave oven, and the sides and the upper surface of the microwave oven are covered. It includes an outer case 26 having a 'c' shape, and a cavity assembly 27 constituting the cooking chamber body.

The components forming the appearance as described above are components that are commonly used in the majority of microwave ovens, and in particular, forming the corners due to the characteristics of the microwave oven forming an approximately rectangular parallelepiped form the front case 25, the outer case 26, and the cavity assembly ( 27 is the intersection of the rear portion 27a and the base plate 28.

As shown in Figure 4, the chamfer 30 is formed at the corner of the microwave oven of the present invention. The chamfer 30 refers to a surface made of a chamfering operation to sharpen sharp edges, and is used in the same sense as the chamfering surface.

As shown in the figure, in the microwave oven of the present invention, all of the chamfers 30 are formed except for both ends of the front upper portion. The reason why the chamfer 30 is not formed on the upper front side as described above is that the chamfering process is performed only on the bottom and rear parts which are not visually noticeable to the user, and the visually prominent front upper part is not good in appearance.

In addition, the front case of most microwave ovens, unlike the side or rear, use a synthetic plastic with elasticity and does not crush well, so it is superior in rigidity than the corners of the metal material of the rear or bottom to form a chamfer (30). You don't have to.

However, in the present invention, there is no particular limitation on the chamfer forming portion, and the chamfer 30 may be formed at all eight corners, but the chamfer 30 is preferably formed at the corners of the four rear portions.

In forming the chamfer 30, a part of the panel forming the appearance of the microwave oven may be cut, and then a triangular chamfer piece may be welded, and the outer case 26 may be processed to form a chamfer surface, and the outer case ( 26) it is also possible to bend the end of the base plate 28 or cavity assembly 27 located inside.

6 is a view showing an angle formed by the chamfer surface and the outer edge portion when forming the chamfer 30 surface of the microwave oven according to the present invention.

As shown in the figure, the chamfer 30 of the present invention is such that the angle formed by the edge extension line 4 of the three-side appearance case and the edge portion 31 of the chamfer 30 is 30 ° ~ 60 ° Suitable. When the chamfer is formed outside the angle of the above range, sharp edges are formed again, so it is difficult to expect the effect of the present invention.

7 is a schematic perspective view showing the microwave oven according to the present invention packaged by the shock absorbing material (2).

When the shock absorber 2 wraps the microwave oven, the rectangular corner of the microwave oven is conventionally fitted to the inner surface of the shock absorber 2, but the microwave oven of the present invention has a chamfer 30 so that the shock absorber is formed. The inner edge portion of (2) may be free from the inner edge portion, or the inner edge portion of the shock absorber may be reinforced to be joined to the chamfer 30 surface.

Therefore, even if the case falls to the corner portion during transportation of the chamfer (30) surface to distribute the impact, the shock absorber 2 absorbs more because the amount of shock absorber 2 can prevent the edge damage of the microwave oven.

The above-described embodiment is merely an example for expressing the technical spirit of the present invention in detail, and it is obvious that the position, shape, and material of the component may be changed within the scope without departing from the technical spirit of the present invention.

By forming a chamfer at the corner of the microwave oven, when the product is transported due to inadvertent or unintentional accidents of the product, the amount of impact applied to the corner is significantly reduced to prevent the edge breakage.
