Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a braided net used for cooking an oven, a grill and a microwave oven by a high frequency heating device and a supporting method thereof.

2. Description of the Related Art In high-frequency heating devices, a large amount of drainage net is used to finish cooking well and to perform two-step cooking.
If the slatted net is not placed properly, the objects to be heated or the container may fall and stain the inside of the refrigerator, cooking may not be possible, the container may be damaged, or the slatted net may slip during use, resulting in injury. I was afraid to do it. Further, during cooking with high frequency electromagnetic waves, there is a risk that sparks may occur between the saw net and the wall of the heating chamber unless the saw net is normally held.

In order to deal with the above problems, FIG.
The means shown in FIG. 7 are used. That is, the rectangular protrusions 33A and 33B are formed at four positions on the left and right of the outer peripheral frame 32 of the saw net 31, and the width of the front two of the four protrusions is formed to be slightly larger than the width of the holder 34. Two convex parts on the side 33
B is wider than the front one. Furthermore, in order to clearly indicate the front-back and up-down directions of the slatted net, the display board 35
Is attached. Characters such as "FLONT" are displayed on the front surface of the display board 35, and a claw 36 is formed on the back surface of the display board 35, and the claw 36 holds the outer peripheral frame 32 of the saw net. There is.

When placing the saw net having the above-mentioned configuration, the saw net 31 is placed in the heating chamber in the direction indicated by the display panel 35, and the holder 34 attached to the side wall of the heating chamber supports the four convex portions 33A, 33B. Holds the net 31. The sludge net can be positioned by the narrow front projection 33A. Further, when the outer peripheral frame 32 of the saw net comes into contact with the rear wall of the heating chamber and is placed by mistake, the front convex portion 33A is disengaged from the holder 34 as shown in FIG. The corner portion 33C of the portion 33B is formed so as to come into contact with the holder 34, and if the object to be heated is placed on the saw net, the convex portion 33B on the rear side is placed on the holder 34 depending on the weight of the object to be heated 37 and the container. Sliding, the sling net becomes stable as shown in FIG. 6 (C).

However, in the method of the conventional example, the width of the convex portion formed on the outer peripheral frame 32 of the saw net is set so that the two on the front side are narrow and the two on the rear side are wide so that they are substantially at the same position from the center. As shown in FIG. 7, the vertical direction is reversed so that the saw net 31 is held.
When placed on the holder 34, only the protrusions 33A and 33B come into contact with the holder 34, which is very unstable and dangerous. Therefore, the display board 35 showing the front-back and up-down directions of the slatted net 31.
Had to be attached, which was disadvantageous in terms of cost.
In addition, the display board held on the drainboard net 31 by the claw 36.
If 35 damages the pawl 36 during handling, it will fall out of the lapping net, making it impossible to distinguish between the front and back and up and down directions, which is also in a dangerous state. In FIG. 6 (D), when the sludge net 31 is placed with its front-back direction reversed, high-frequency electromagnetic waves are radiated while the metal sludge net is in contact with the heating chamber wall, which may cause a spark. was there. Furthermore, even if the front-back and up-down directions are normal, if the outer peripheral frame 32 of the saw net is accidentally attached to the rear wall 38 of the heating chamber and the object to be heated 37 is placed on the saw net, the weight of the object to be heated will cause the sludge to move. Although the net 31 slides and moves to a normal mounting state, this movement is shocking and may damage or damage the container, the holder 34, and the slatted net 31.

The present invention aims to solve the problems encountered in the past, and an object thereof is to provide a means that is easy to use, has a low risk of injury, and is advantageous in terms of cost.

Means for Solving the Problems In order to solve the above problems, a high-frequency heating device according to the present invention includes a left and right side 4 of an outer peripheral frame of a saw net formed of steel rods.
The corner-shaped convex portions are formed at some places, and one of the four convex portions that is point-symmetrical is formed slightly larger than the holder width, and the other pair of convex portion positions is the pair of point-symmetrical convex portion positions. While slightly moving to the center side than the width of the convex portion, another pair of convex portion width is formed by adding (heating chamber depth dimension-slat net depth dimension) to the pair of convex portion widths, and heating. On the left and right side walls of the room, two holders, two in total, are arranged so as to form point symmetry, and a holder that has a pair of point symmetry other than the pair of holders is moved on the wide convex part formed on the slatted net. By moving the holder to the center side of the heating chamber by the same amount as the amount, the mounting position of the holder corresponds to the position of the convex portion formed on the outer peripheral frame of the saw net.

Action According to the above configuration, the convex portion of the saw net for placing and holding the saw net on the holder provided on the side wall of the heating chamber,
A pair of protrusions forming point symmetry is formed to have a narrow width (a = width of C holder) +2 to 3 mm) and another pair of protrusions is formed to have a wide width (b = a + d (heating chamber depth dimension e-saw net) (The depth dimension of the heating chamber), move the position of the wide convex part toward the center side of the heating chamber by an amount slightly larger than the width of the narrow convex part, and move the holder position on the left and right side walls of the heating chamber By mounting the sling net in correspondence with the position of the parts and supporting the sling net, misuse of the sling net can be prevented and the risk can be greatly improved.

For example, when the sludge net is placed upside down on the holder with the vertical direction reversed, the narrow convex portion is removed from the holder, and the wide convex portion is supported by the holder. Therefore, the supporting height of the saw net is different between the left and right, and the saw net attaches with a large inclination, and it is easy for the user to know that it is not in a normal mounting state, and it can be easily returned to the normal state.

As described above, according to the present invention, it is possible to easily determine that a normal state is not set even if the sludge net is erroneously placed on the holder, and there is a risk of sparking, the holder, the slosh net,
It is possible to reduce the risk of damage or breakage of the container or the like.
Further, the display panel is not required, which is advantageous in terms of cost.

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

FIG. 1 (A) is a perspective view showing a braided net of the present invention, and FIG. 1 (B) shows the positional relationship of the holder attached to the side wall of the heating chamber and the placement state of the braided net from above. Second
In FIGS. (A) and (B), the situation when the outer peripheral frame of the saw net is mistakenly brought into contact with the rear wall of the heating chamber and attached is shown from above and in cross section. FIG. 3 shows a situation where the present invention saw net is placed upside down, and FIG. 4 shows a situation of use in a high frequency heating device.

In the figure, 1 is a saw net, 2 is a perimeter frame of the saw net, 3A, 3B
Is a convex portion formed on the outer peripheral frame, 4 heating chambers, 4A is a heating chamber side wall,
4B is a rear wall of the heating chamber, 5 is a resin holder fixed to the side wall of the heating chamber, 6 is a door, and 7 is an operation panel. Further, a and b indicate the widths of the convex portions 3A and 3B, respectively, and C indicates the width of the holder 5. Further, d is the depth of the heating chamber, e is the depth of the saw net, and f is the amount of movement of the protrusion 3B with respect to the protrusion 3A.

In the screen 1 of the present invention, the width of the two convex portions 3A, which are in point symmetry, among the convex portions formed on the outer peripheral frame 2 is narrowed (a =
c + (2 to 3 mm)), and another pair of convex portions 3B having point symmetry are formed to have a wide width (b = a + (de)), and the pair of widened convex portions 3B is formed to a convex portion 3A. Since it is formed by moving only the amount f slightly larger than the width a to the center side of the heating chamber, a display panel for clearly indicating the front-back and up-down directions of the saw net 1 is not required, which is not only easy to handle but also cost effective. For example, when the outer peripheral frame 2 of the saw net 1 is accidentally brought into contact with the heating chamber rear wall 4B and placed on the holder 5, the narrow convex portion 3A comes off the holder 5. On the other hand, since the wide convex portion 3B is supported by the holder 5,
As shown in FIG. 2 (B), the supported heights of the saw net 1 are greatly different between the left and right sides, and the saw net is mounted with a large inclination. Accordingly, the user can easily determine that the object 8 is not in the normal mounting state, and either return the object 8 to the normal mounting state before placing the object 8 to be heated or place the object 8 to be heated on the saw net 1. Also, the impact can be corrected to a normal state without acting on the holder 5 and the saw net 1. Therefore, not only the damage to the parts is reduced, but also the risk of injury due to the falling off of the sludge net is eliminated. In addition, even when the slats 1 according to the present invention are erroneously placed on the holder 5 in the vertical direction, as shown in FIG. Since the portion 3B is supported by the holder 5, also in this case, as shown in FIG. Therefore, even when the vertical direction of the sludge net 1 is reversed, the user can easily notice that the normal mounting state is not present, and the normal state can be restored.

The holder 5 fixed to the heating chamber side wall 4A corresponds to the positions of the convex portions 3A and 3B formed on the outer peripheral frame 2 of the saw net 1, and the holder corresponding to the wide convex portion 3B is the other pair. It is fixed by moving it to the center side of the heating chamber from the holder position by the same amount as the displacement amount f of the convex portion 3B of the saw net.

In this way, the sludge net 1 of the present invention is placed on the holder 5 fixed to the heating chamber side wall 4A, and the object 8 to be heated is placed on the slatted net 1.
Then, if the door 6 of the high-frequency heating device is closed and the cooking method, the cooking time and the like are instructed on the operation panel 7 to start the cooking, the desired cooking can be performed more safely. In addition,
In the embodiment of the present invention, a = 14 mm, b = 40 mm, C = 11 mm,
It was f = 20 mm.

As described above, according to the present invention, the following many effects can be expected.

(1) A narrow convex portion and a wide convex portion formed on the outer periphery of the braided net are arranged so as to form point symmetry, and a pair of wide convex portions are moved toward the heating chamber center line side. Then
Further, by arranging the holder fixed to the side wall of the heating chamber so as to correspond to the position of the convex portion of the braided net, the directionality of the braided net in the front-rear direction is eliminated, and there is no need to distinguish the front-rear direction, which facilitates handling.

(2) The pair of narrow projections formed on the outer peripheral frame of the sludge net is set to be slightly larger than the width of the holder so that the slosh net is supported in the normal position, and the other pair of wide protrusions is , The width of the narrow convex portion (heating chamber depth dimension −
The depth of the sludge net is added, and the entire convex portion is moved toward the center of the heating chamber by an amount slightly larger than the width of the narrow convex portion. Even if it is mounted or mounted by contacting the outer peripheral frame of the screen with the rear wall of the heating chamber, the screen is greatly inclined in the left-right direction, and the user can easily judge that the screen is not in a normal state. Therefore, it is possible to eliminate the risk of injury or injury due to the possibility of sparks and the dropping of the saw net.

(3) The directionality in the front-rear direction is eliminated, and errors in the up-down direction can be easily recognized, so that a display panel for indicating the front-rear direction and the up-down direction is not required, which is advantageous in terms of cost. Further, the problem that the display panel comes off and the directions cannot be distinguished during use is solved.
