Description

{A supporting structure of crusty tray for microwave oven}

The present invention relates to a support structure, and more particularly, to a support structure of a crusty tray used in a microwave oven.

In general, a microwave oven uses dielectric heating to project microwaves (2450 MHz) onto food (dielectric) to cause food molecules to vibrate and to heat and cook in the food itself.

The microwave oven as described above is configured to cook in a state where food is settled by installing a tray which is rotated or not rotated inside the cavity.

In particular, the use state of the so-called crusty tray configured to generate high heat in the tray itself to improve cooking efficiency is a cavity 51 formed in a box shape such that the cooking chamber 50 is formed therein as shown in FIGS. 3 and 4. In addition to seating the crusty tray 53 on the upper surface of the tray 52 installed to rotate inside, it is used in a state where the food (not shown) is seated on the upper surface.

The crusty tray 53 is installed on the bottom of the disc-shaped main body 54 on which food is placed, and on the bottom of the main body 54, and to adjust the height of a heater (not shown) installed in a microwave oven. It is composed of a fixed means of a predetermined height, the outer surface of the main body 54 is coated with a heating material such as ferrite (not shown) for the heat generation.

In addition, the support means is a coupling hole 55 is formed on both sides and the bracket 56 is fixed to the bottom surface of the main body 54, and the coupling protrusion 57 is fitted to the coupling hole 55 once It is formed in the "V" shaped legs 58 formed opposite to and molded of a nonferrous metal material such as plastic.

Here, the legs 58 are formed of plastic in order to prevent sparks from occurring in the legs 58 due to high frequency, etc., thereby preventing performance degradation and breakage of the microwave oven.

Referring to the operation of the crusty tray 53, when the high frequency is radiated into the cooking chamber according to the operation of the microwave oven, the high frequency is irradiated to the crusty tray 53.

When the high frequency is irradiated to the crusty tray 53, the above-described heat generating material generates heat, and the cooking efficiency of foods seated on the crusty tray 53 by the heat of the heat generating material is further improved.

However, when the plastic legs are used to support the bottom of the crusty tray as described above, when the temperature of the crusty tray body reaches a certain temperature or more, the stiffness of the legs is lowered. The leg is deformed and there is a problem that the leg is separated or loosened from the tray body by the deformation.

Accordingly, an object of the present invention is to solve the above problems, to provide a crusty tray support structure for a microwave oven that can prevent the legs maintaining a constant height of the crusty tray from being deformed by high heat. .

Microwave tray support structure for microwave oven according to the present invention includes a main body is installed on the outer surface and the bracket is fixed to the heating surface and the legs configured to maintain a constant height of the main body by intermittently coupled to the bracket In the microwave tray support structure for a microwave oven, the leg is a bending member which is connected to the lower side and extends toward the upper side, and inside the gap of the leg, the tray body and the weight of the food An extension means for generating a force in a direction orthogonal to the force acting in the vertical direction and extending in the upper end of the leg is installed.

1 and 2 are a perspective view and an assembled side view showing a crusty tray support structure for a microwave oven according to the present invention, the force acting in the vertical direction of the tray body 54 by the weight of the tray body 54 and the food. Expansion means for forming a force in a direction orthogonal to P and pressurizing the upper end of the leg 58 is provided on the upper end of the leg 58 which is a cracked portion engaged with the bracket 56.

The leg 58 is a bending member that is connected to the lower side and extended toward the upper side.

That is, when the force P in the vertical direction in the tray main body 54 acts downward, the upper end of the leg 58 is forced to be bent inward, and thus a reverse force capable of countering the force described above. By causing the above expansion means to be generated, it is possible to prevent the deformation of the leg (58).

The expansion means is a projection (1) formed opposite to the upper inner surface of the open portion of the leg 58, both ends are fitted and fixed to the protrusion (1) and to apply elasticity in the opening direction of the leg (58). It is comprised by the spring 2 comprised.

Of course, the elasticity of the spring 2 has the elasticity to withstand when the weight of the tray body 54 and the weight of the food is applied to the leg when the leg is heated to decrease the rigidity.

Referring to the operation and effect of the present invention as described above, in order to assemble the crusty tray 53, the operator couples the spring 2 to the protrusion 1 located inside the leg 58, and then the legs ( 58), the gap is pressed to narrow the distance.

When the legs 58 are narrowed, the coupling protrusions 57 of the legs 58 are coupled to the coupling holes 55 of the brackets 56 fixed to the bottom surface of the krusty tray body 54 to complete the assembly. .

At this time, since the inside of the leg is supported by the elasticity of the spring (2) when the compression for the assembly of the leg (58), even if the operator presses over a certain force by the spring (2) Since it is elastically supported, the leg 58 will not be damaged.

In order to use the crusty tray 53 assembled as described above, the user seats the crusty tray 53 on the tray 52 for cooking food.

When the crusty tray 53 is seated on the tray 52, the food is placed on the upper surface of the tray 52. A heater for cooking the food by the legs 58 of the crusty tray 53 and the like. The height of is appropriate.

When the microwave oven is operated in this state, the high frequency heats the above-mentioned food and heats the heat generating member of the crusty tray main body 54.

When the heating element is heated, the cooking efficiency of the upper surface is further improved. In this case, when the temperature of the main body 54 is heated above a predetermined temperature, the metal bracket 56 fixed to the bottom of the main body 54 is provided. The leg 58 is heated through.

When the leg 58 made of plastic is heated, the rigidity is lowered, and the upper surface of the leg 58 is bent inward by the above-mentioned rigidity drop. However, the spring 2 causes the leg 58 to move outward. Because it is wide open legs 58 will not be deformed.

That is, even when the engaging projection 57 of the leg 58 whose rigidity is deteriorated is about to be separated from the coupling hole 55 by the force P which is urged in the vertical direction from the upper surface of the tray main body 54, the spring 2 is The portion of the coupling protrusion 57 is brought into close contact with the coupling hole 55 of the bracket 56 so that the legs are not separated from the bracket 56.

As described above, the present invention has an effect of preventing the deformation of the leg for supporting the crusty tray that generates high heat in the main body by elasticity by the spring.
