Hook of Doorpanel in Microwave oven}
[14] The present invention relates to a microwave oven, and more particularly, to a hook for fixing a door glass attached to a door panel of a microwave oven.
[15] 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.
[16] 1 is a perspective view showing the appearance of a conventional general microwave oven.
[17] 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.
[18] 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.
[19] 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.
[20] 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.
[21] 2 is a perspective view schematically illustrating the door assembly of the microwave oven.
[22] As shown in the drawing, a door 14 of a typical microwave oven includes a door panel 141 to which a door handle 145 is attached, a door glass 142 mounted inside from the rear of the door panel 141, and A door frame 143 attached to the inside of the door panel 141 at the rear of the door glass 142 and a choke cover 144 formed at the rear of the door frame 143 are configured.
[23] The door panel 141 and the door glass 142 are coupled by a plurality of hooks 146 formed inside the door panel 141.
[24] 3 is a perspective view illustrating a hook 146 formed on a conventional general door panel to fasten a door glass.
[25] As shown in the figure, the hook 146 of the door panel 141 is a hook head 146a for preventing the fastened glass 142 is separated, and a hook body 146b for supporting the hook head 146a. And a rib 146c for fixing the hook body 146b.
[26] In the hook 146 having the above configuration, the hook head 146a is not flipped back when the door glass 142 is fastened. That is, since the rib 146c fixes the hook head 146a and the hook body 146b, the hook head 146a or the hook body 146b cannot move at all.
[27] In order to mount the door glass 142 on the door panel 141 having the hook 146, the method as shown in FIG.
[28] 4 is a cross-sectional view illustrating a state in which an operator opens the door panel 141 when the door glass 142 is fastened.
[29] As shown in FIG. 4, the operator grasps both sides of the door panel 141 and exerts an external force to spread it outward and the hook head 146a to be opened to both sides, and then inserts the door glass 142 into the hook body 146b. When the door panel 141 is placed, the door panel 141 is returned to its original shape and the door glass 142 is mounted on the hook 146.
[30] Mounting the door glass 142 on the door panel 141 having the hook 146 of the above structure is a complicated process and wasteful of manpower, and also bends the door panel 141 forcibly. 141 has a problem that can be modified.
[31] The present invention has been made in order to solve the problems of the prior art described above, by improving the hook structure of the door panel for fastening the door glass of the microwave oven so that the hook head flows in the conventional fixing structure, the operator forcibly bends the door panel. It is an object of the present invention to provide a hook of a microwave door panel that can be easily fastened without the door glass.

[10] 141: door panel 142: door glass
[11] 143: door frame 144: choke cover
[12] 246: hook 246a: hookhead
[13] 246b: connection portion 246c: hook support portion
[32] In order to achieve the above object, the present invention provides a hook of a microwave oven door panel, wherein the hook has two hook support parts attached to and fixed to the door panel surface; A connection part connecting between the hook support parts; It provides a hook of the microwave oven door panel comprising a hook head formed in the connection portion.
[33] In particular, the connection portion formed with the hook head portion is made of a plastic material having elasticity that can be rotated back to 50 ° or less by rotating around the portion fixed to the support portion is characterized in that it can be restored after some twist.
[34] The configuration of the hook of the present invention and the microwave oven door panel will be described in more detail with reference to the accompanying drawings. For reference, prior to describing the configuration of the present invention, in order to avoid duplication of description, the same reference numerals as those of the prior art will be referred to.
[35] 5 is a perspective view showing a preferred embodiment of a hook of a microwave oven door panel according to the present invention, Figure 6 is a side view of the hook.
[36] 5 and 6, the hook 246 of the microwave oven door panel 141 according to the present invention is installed on the inner surface of the door panel 141, is fixed to the door panel 141 surface is installed It consists of two support parts 246c, the connection part 246b which connects mutually above the said two hook support parts 246c, and the hook head 246a formed in the said connection part 246b.
[37] The support part 246c of the hook is fixedly attached to the inner surface of the door panel 141 in an inflexible manner. The support part 246c is spaced apart from each other and is installed in two places. A connecting part 246b for connecting the support parts is formed on both upper parts of the support part 246c, and a hook head 246a is attached to the connecting part 246b. . The distance between the hook head 246a and the surface of the door panel 141 preferably matches the thickness of the door glass 142.
[38] The material of the hook 246 is preferably a plastic material, in particular, the connection portion 246b is characterized in that the elastic resilience is provided with a plastic having a degree of ductility to the degree of twist.
[39] The hook head 246a may be rotated at an angle with respect to the connecting portion 246b as shown in the arrow direction shown in the drawing, and returned after the rotation by the elastic restoring force of the connecting portion 246b.
[40] Hereinafter, the process of mounting the door glass 142 on the door panel 141 in which the hook 246 of the present invention is formed will be described with reference to FIGS. 7A and 7B.
[41] 7A is a cross-sectional view showing a state immediately before the door glass 142 is inserted into the hook 246 on the door panel 141, and FIG. 7B is a state in which the door glass 142 is completely mounted to the door panel 141. It is a cross-sectional view
[42] As shown in FIG. 7A, the door glass 142 is pressed down on the hook 246 of the present invention on the door panel 141 while the door panel 141 is placed below. When pressed as described above, the hook support portion 246c is fixed, but the connection portion 246b and the hook head 246a is rotated by an angle by the pressure pressing the door glass 142, the door glass 142 is the Enter the inclined surface of the hook head 246a.
[43] The connecting part 246b is slightly twisted, but the connecting part material has a characteristic of being restored again without being broken in a torsion of 50 ° or less, and the process of inserting the door glass 142 is made instantaneously. Does not affect stiffness
[44] As shown in FIG. 7B, after the door glass 142 is inserted between the door panel 141 surface and the hook head 246a, the connecting portion 246b and the hook head 246a are restored to their original positions, and the door glass ( 142 is prevented from being detached by the hookhead 246a.
[45] The present invention can be easily finished in the process of mounting the door glass to the door panel only by pressing the door glass without the operator forcibly bending the door panel as in the prior art.
[46] This improves productivity by reducing unnecessary manpower waste and prevents deformation of the door panel, thereby ensuring quality reliability.
