Abstract

PURPOSE:To prevent an erroneous usage of a grid net and reduce an occurrence of spark and a dangerous state of breakage by a method wherein a holder is fixed while right and left side wall positions for the holder within a heating chamber are being corresponded to the projection positions of the grid net and the grid net is supported. CONSTITUTION:A grid net 1 is made such that a width of two projections 3A in a point symmetrical relation of the projections formed at an outer circumferential frame 2 is made small [a = c + (2 to 3mm)], a width of a pair of projections 3B forming another spot symmetrical relation is made large [b = a + (d - e)] and at the same time a pair of projections 3B are moved toward a central part of a heating chamber by an amount (f) slightly larger than a width (a) of the projections 3A, resulting in that a display panel for clearly indicating a vertical or a lateral direction of the grid net 1 can be eliminated. Its handling is convenient and its cost is also effective. For example, in case that the outer circumferential frame 2 of the grid net 1 is acciden tally contacted with a rear wall 4B of the heating chamber and placed on the holder 5, the narrow projections 3A are removed from the holder 5. In turn, the wide projections 3B are supported by the holder 5, so that the grid net is largely inclined and fixed. Accordingly, a user can acknowledge easily that the device is not in its normal fixing state.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a slatted grid used for open cooking, grilling, and microwave cooking using high-frequency heating devices, and a method for supporting the same.

In conventional high-frequency heating devices, slatted mesh is often used to finish cooking well or to perform two-stage cooking, but if the slatted mesh is not placed properly, the object or container to be heated may fall. There was a risk of soiling the inside of the refrigerator, making it impossible to cook, damaging the container, or causing injury due to the grates slipping during use. Furthermore, during cooking using high-frequency electromagnetic waves, if the grates are not properly held, there is a risk of sparks occurring between the grates and the walls of the heating chamber.

In order to deal with the above-mentioned problems, conventional measures as shown in FIGS. 5 to 7 have been taken.

That is, angular convex portions 33A and 33B are formed at four places on the left and right of the outer peripheral frame 32 of the drainboard net 31, and the width of the front two of the four convex portions is formed to be slightly larger than the width of the holder 34, and the rear The two protrusions 33B on the sides are formed to have a wider width than the one on the front side. Furthermore, a display board 35 is attached to clearly indicate the front and back and up and down directions of the grid. Display panel 3
5 is displayed with characters such as "FLONT", and claws 36 are formed on the back surface of the display board 35, and the outer peripheral frame 32 of the grating net is held between the claws 36.

When placing the gridiron net having the above configuration, put the gridiron net 31 into the heating chamber in the direction indicated by the display panel 35, and use the holder 34 attached to the side wall of the heating chamber to set the four convex portions 33A, 33B.
The grate net 31 is held by supporting it. The positioning of the grid can be performed using the narrow front protrusion 33A.

Furthermore, if the outer circumferential frame 32 of the grid is placed in contact with the rear wall of the heating chamber by mistake, the front protrusion 33A will come off the holder 34 as shown in FIG. 6(B), and the rear Convex portion 33B
The corner portion 33C of the is formed so as to be in contact with the holder 34, and when the object to be heated is placed on the grid, the object to be heated 3
7 and the weight of the container, the protrusion 33B on the rear side may be attached to the holder 3.
4, and the grid becomes stable as shown in FIG. 6(C).

Problems to be Solved by the Invention However, in the conventional method, the width of the protrusions formed on the outer peripheral frame 32 of the slatted mesh is narrower on the two front sides and wider on the two rear sides, so that they are located at approximately the same position from the center. As shown in Figure 7, you can turn the drainboard upside down! 1liI31
When placed on the holder 34, only the protrusions 33A and 33B will come into contact with the holder 34, resulting in a very unstable and dangerous situation. Therefore, a display panel 35 indicating the front and rear directions of the grid 31 must be attached, which is disadvantageous in terms of cost. In addition, the display panel 35 held on the gridiron screen 31 by the claws 36 may be damaged during handling.
If it is damaged, it will fall off from the grid, making it impossible to distinguish between the front and back and the top and bottom, which is also a dangerous situation.

In Fig. 6 (D), if the grid grid 31 is placed with the front and back directions reversed, high frequency electromagnetic waves will be emitted while the metal grid grid is in contact with the heating chamber wall, which may cause sparks. was there. Furthermore, even if the front-back and up-down directions are normal, if the outer peripheral frame 32 of the grid is accidentally attached to the rear wall 38 of the heating chamber, if the object to be heated 37 is placed on the grid, the weight of the object will be reduced. When the grate net 31 is normally installed, it slides and moves, but this movement is shocking and may damage the container, the holder 34, or the grate net 31.
There was also a risk of damage.

The present invention aims to solve the problems seen in the past, and is easy to use and has little risk of injury.
The purpose is to provide a means that is advantageous in terms of cost.

Means for Solving the Problems In order to solve the above problems, the high frequency heating device of the present invention includes:
Corner-shaped protrusions are formed at four places on the left and right of the outer peripheral frame of the grid made of steel rods, and one pair of the four protrusions is formed to be slightly symmetrical than the holder width, and the other pair The position of the convex part is moved to the center side of the position of the pair of convex parts that emphasize point symmetry, and is slightly larger than the width of the convex part, and the width of the other pair of convex parts is set to the width of the pair of convex parts (heating A total of 4 holders, 2 each on the left and right side walls of the heating chamber, are placed symmetrically so that the other holders are more powerful than a pair of holders. The drain holder was moved toward the center of the heating chamber by the same distance as the wide protrusion formed on the grate screen, and the holder was installed at a position corresponding to the protrusion formed on the outer frame of the grate screen. It is something.

Function According to the above configuration, the convex portion of the grating net for placing and holding the grating net on the holder provided on the side wall of the heating chamber is narrowed in width (a=C Width of the holder) + 2 to 3) is formed, and the other pair of protrusions are made wider ((b
= a + d (heating chamber depth dimension e - depth dimension of the slatted mesh), and at the same time move the position of the wide convex part toward the center of the heating chamber by an amount slightly larger than the width of the narrow convex part,
By attaching the holders on the left and right side walls of the heating chamber so as to correspond to the positions of the convex portions of the grid to support the grid, the misuse of the grid can be prevented and the danger greatly reduced.

For example, if the grid is placed upside down on a holder, the narrower protrusions will come off the holder, and the wider protrusions will be supported by the holder.

Therefore, the supporting heights of the left and right sides of the grid are different, and the grid is installed at a large angle, making it easy for the user to know that the grid is not placed in a normal position, and to easily return it to its normal state.

As described above, according to the present invention, even if the grate net is placed on the holder by mistake, it can be easily determined that it is not in a normal state, and there is a risk of spark generation and damage to the holder, grate net, container, etc. The risk of damage can be reduced. In addition, a display panel is not required, which is advantageous in terms of cost.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1(A) is a perspective view showing the slatted net of the present invention,
Figure (B) shows the positional relationship of the holder attached to the side wall of the heating chamber and the placement of the grating net from above. Figure 2 (
A) and (B) show the situation when the outer circumferential frame of the slatted mesh is mistakenly installed in contact with the rear wall of the heating chamber, viewed from above and in cross section. Fig. 3 shows the situation when the grate net of the present invention is placed upside down;
The figure shows how it is used in a high-frequency heating device.

In the figure, 1 is a slatted net, 2 is an outer peripheral frame of the slatted net, 3A, 3
B indicates a convex portion formed on the outer peripheral frame, 4 heating chambers, 4A indicates the side wall of the heating chamber, 4B indicates the rear wall of the heating chamber, 5 indicates a resin holder fixed to the side wall of the heating chamber, 6 indicates the door, and 7 indicates the operation panel. ing. Moreover, ab indicates the width of the convex portions 3A and 3B, respectively, and C indicates the width of the holder 5. Furthermore, d is the depth dimension of the heating chamber, e is the depth dimension of the slatted mesh, and f is the convex portion 3.
The amount of movement of B with respect to the convex portion 3A is shown.

In the drainboard net 1 of the present invention, the width of the two point-symmetrical convex portions 3A among the convex portions formed on the outer peripheral frame 2 is narrower than L (a
=c+ (2nd to 3rd tone)), the width of the pair of convex portions 3B that emphasizes the symmetry of other points is widened <(b=a+(d−〇)), and the pair of convex portions 3B with a wide width is formed. By moving only the amount r, which is slightly larger than the width a of the convex portion 3A, toward the center of the heating chamber, there is no need for a display panel to clearly indicate the front and rear directions of the grating, making it easier to handle. For example, if the outer peripheral frame 2 of the grate mesh 1 is accidentally placed on the holder 5 in contact with the rear wall 4B of the heating chamber, the narrow convex portion 3A will be removed from the holder. 5. On the other hand, since the wide convex portion 3B is supported by the holder 5, as shown in FIG. Therefore, the user can easily determine that the installation condition is not normal, and either return the object 8 to the normal installation condition before placing the object 8 on it, or place the object 8 on the gridiron. Even after being placed on the net 1, the holder 5 and the slatted net 1 can be corrected to their normal state without any impact force acting on them.Therefore, damage to parts is reduced. This also eliminates the risk of injury due to the slatted net falling off.Furthermore, the slatted net 1 of the present invention
Even if it is placed on the holder 5 in the wrong vertical direction,
As shown in FIG. 3, the narrow protrusion 3A is located on the holder 5.
Since the wide convex portion 3B that is separated from the holder 5 is supported by the holder 5, the drainboard Mi41 will be attached at a large inclination as shown in FIG. 3 in this case as well. Therefore, even if the vertical direction of the grate net 1 is reversed, the user can easily notice that it is not placed in the normal state and can return it to the normal state.

Note that the holders 5 fixed to the heating chamber side wall 4A correspond to the positions of the protrusions 3A and 3B formed on the outer peripheral frame 2 of the grates 1, and the holders corresponding to the wide protrusions 3B are located in the other pair. The holder is moved toward the center of the heating chamber by an amount equal to the displacement f of the convex portion 3B of the grid and is fixed.

In this way, the grates 1 of the present invention are placed on the holder 5 fixed to the heating chamber side wall 4A, the object to be heated 8 is placed on the grates M41, the door 6 of the high-frequency heating device is closed, and the operation panel 7 is opened. If you start cooking by instructing the cooking method, cooking time, etc., you can more safely perform the desired cooking. In addition, in the embodiment of the present invention, a = 14+nm, b = 4
0 mm, C=11 mm, and r-20 mm. Effects of the Invention As described above, according to the present invention, the following many effects can be expected.

(1) The narrow protrusions and wide protrusions formed on the outer peripheral frame of the slatted mesh are arranged so as to emphasize point symmetry, and the pair of wide protrusions is moved toward the center line of the heating chamber. By arranging the holders fixed to the side walls of the heating chamber so as to correspond to the positions of the convex parts of the grid, the grid has no front-to-back directionality, and there is no need to distinguish between the front and rear directions, making it easier to handle. Become.

(2) A pair of narrow protrusions formed on the outer peripheral frame of the drainboard mesh are made slightly larger than the width of the holder to support the drainboard mesh in its normal position, and the other pair of wide protrusions are , was formed by adding (heating chamber depth dimension - slat mesh depth dimension) to the width of the narrow convex part and moving the entire convex part towards the center of the heating chamber by an amount slightly larger than the width of the narrow convex part. Therefore, even if the grate screen is placed on the holder with the wrong vertical direction, or if the grate screen outer frame is attached to the rear wall of the heating chamber, the grate screen will tilt significantly in the left and right direction, causing the user to It can be easily determined that the condition is not normal. Therefore, it is possible to eliminate the risk of sparks and the risk of damage or injury due to the grate mesh falling off.

(3) Since there is no directionality in the front-rear direction and errors in the up-down direction are easily recognized, there is no need for a display panel to indicate the front-rear and up-down directions, which is advantageous in terms of cost. Further, the problem of the display panel coming off during use and making it impossible to distinguish the direction is solved.
