Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates mainly to a microwave oven with an improved cooking dish.

[0002]

2. Description of the Related Art Conventionally, in the microwave oven,
Oven heating and range heating are possible. Generally, a metal cooking plate (oven plate) with good thermal conductivity is used for the oven heating, and glass is used for the range heating to avoid generation of spark discharge. The cooking plate (range plate) made of is used.

[0003]

In the case of the above-mentioned conventional one, it is necessary to properly use the oven plate and the range dish for the oven heating and the range heating. Especially, when the combination heating of the range heating and the oven heating is performed. It was necessary to replace the oven dish and the range dish when switching the heating during cooking, and therefore it was necessary to stop the cooking once, and continuous combi cooking was impossible.

On the other hand, JP-A-62-172029
The publication discloses a cooking dish that can be used for both oven heating and range heating. Although this cooking dish is made of metal, it has an insulator on its legs and is placed on a metal rotating plate (saucepan) so that the insulator makes contact with it to maintain the required insulation distance. Occasionally, it is possible to avoid the occurrence of spark discharge between the rotating plate and the cooking dish.

However, in this structure, an insulating material is required for each of a plurality of legs, resulting in a high cost. Further, since the rotary plate has a non-perforated shape and cannot pass radiant heat, it is not suitable for toast cooking which requires radiant heat.

The present invention has been made in view of the above circumstances, and therefore an object thereof is not to replace the oven plate and the range plate when performing the combined cooking of the range heating and the oven heating. Another object of the present invention is to provide a microwave oven that can provide cooking plates at low cost and can also perform radiant heat cooking such as toast cooking.

[0007]

In order to achieve the above object, in the microwave oven of the present invention, there is one capable of oven heating and range heating, and is made of a metal rotation driven by a drive device. A net and a metal cooking dish placed on the rotary net and rotated, the cooking dish having a diameter larger than that of the rotary net, and the outer peripheral edge of which is curled outward. Is characterized by.

In this case, the outer peripheral edge portion of the cooking dish may be located above the outer peripheral edge portion of the rotary net. The outer peripheral edge of the rotary net may be curled inward. in addition,
The portion of the rotary dish on which the cooking dish is placed may be formed in a continuous body, and the portion of the cooking dish placed on the rotary dish may be formed in a continuous body.

[0009]

According to the above-mentioned means, since the metal rotary mesh allows radiant heat to pass through the mesh, cooking (toast cooking, etc.) that requires radiant heat can be performed well.
However, the peripheral portion of each hole in the mesh portion can serve as an electrode during range heating, whereas, as described above, the metal cooking dish having a diameter larger than that of the rotary net serves as the electrode of the cooking dish. The outer peripheral edge portion that is a portion to be obtained is located outside the peripheral edge portion of each hole of the mesh portion of the rotary net, and is located outside the outer peripheral edge portion that can further serve as an electrode of the rotary net. . In addition, in addition, in the case where the outer peripheral edge portion of the cooking dish is curled outward, the outer peripheral edge portion of the cooking dish is further distanced from the outer peripheral edge portion of the rotating net, and a large required insulation distance is secured. Thus, spark discharge does not occur even if a metal cooking dish is used during range heating, and it is possible to use it, so replace the cooking dish when performing combined cooking with range heating and oven heating, It does not require an insulator or the like and may be unnecessary.

Further, in that case, in particular, in the case where the outer peripheral edge of the cooking dish is positioned above the outer peripheral edge of the rotary net, and in the case where the outer peripheral edge of the rotary net is curled inward, The outer peripheral edge portion of the cooking dish can be moved further away from the outer peripheral edge portion of the rotary net, and the required insulation distance can be further increased.

In addition, in the case where the portion of the rotary net on which the cooking dish is placed is formed in a continuous body, or the portion of the cooking dish that is placed in the rotary net is formed in a continuous body, There is no part that can be an electrode in the contact part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. First, FIG. 2 shows a cooking chamber 1 commonly used for oven heating and range heating.
The outer shell of this is an inner box 2, which is arranged in an outer box (not shown). The cooking chamber 1 is provided with an upper heater 3 for heating an oven in an upper portion inside and a lower heater 4 for heating an oven in an outer lower portion as well. In addition, a magnetron 5 for oscillating microwaves for heating a microwave oven is arranged outside the cooking chamber 1, and the inside of the cooking chamber 1 is connected by a waveguide 6.

Although not shown in detail, a drive unit 7 having a motor as a drive source is arranged in the center of the outer lower portion of the cooking chamber 1. An output shaft 8 of the drive unit 7 is inserted into the center of the inner lower portion of the cooking chamber 1. The center of the rotary net 9 is attached to the upper end of the rotary net 9 so that the rotary net 9 can be driven to rotate. This rotary net 9 is made of metal, and in detail, it has a circular shape as shown in FIG.
Except for the peripheral portion 9a, most of the remaining portion 9b is formed in a mesh shape, and the peripheral portion 9a is formed in a continuous body shape without holes or breaks. The peripheral portion 9a is also formed in an inverted U-shaped cross section as shown in FIGS.

On the other hand, the cooking dish 10 placed on the rotating net 9 and rotated is also made of metal.
Is formed by a circular disk-shaped dish main body 11 and a circular ring-shaped base body 12 welded and fixed to a lower surface of the disc base body 11 by a plurality of leg portions 12a.
It is designed to be placed on a. Thus, the rotary net 9 is formed such that both the base 12 and the dish main body 11 are larger in diameter than the rotary net 9, and the outer peripheral edge portion 12b of the base 12 is curled outward.

The outer peripheral edge portion 12b of the base 12 is positioned above the outer edge of the peripheral portion 9a of the rotary net 9, that is, the outer peripheral edge portion 9c of the entire rotary net 9 as shown by the dimension A in FIG. I am also doing it. Further, the base body 12 which is a portion to be placed on the rotary net 9 of the cooking dish 10 is also formed in a continuous body shape without holes or breaks.

Now, in the case of the configuration as described above,
The outer peripheral edge portion 12b of the base plate 12 of the cooking dish 10 that can serve as an electrode by receiving the microwave supplied from the magnetron 5 at the time of heating the range is formed by forming the cooking dish 10 to have a diameter larger than that of the rotating net 9. Similarly, it is located outside each hole peripheral portion of the mesh portion 9b which can be an electrode and the outer edge portion (outer peripheral edge portion) 9c of the peripheral portion 9a. And
In addition, by curling the outer peripheral edge portion 12b of the base 12 of the cooking dish 10 outwardly, the outer peripheral edge portion (12b) of the cooking dish 10 is further separated from the outer peripheral edge portion 9c of the rotary net 9 and necessary. A large insulation distance is secured. Thus,
Even if the cooking dish 10 made of metal is used at the time of heating the range, the spark discharge does not occur, and the dish can be used.

Therefore, it is possible to perform the combined cooking of the range heating and the oven heating continuously without replacing the conventional oven plate and range plate, and as a result, the cooking menu can be prepared. It can be increased if possible.

Moreover, in this case, Japanese Patent Laid-Open No. 62-2720
Since the cooking plate 10 alone can achieve the above without requiring a large number of insulators such as the cooking plate shown in Japanese Patent Publication No. 29, it can be provided at low cost. Furthermore, since the rotary net 9 allows radiant heat to pass through the mesh portion 9b,
Cooking (toast cooking, etc.) that requires radiant heat can be performed well.

In addition, since the outer peripheral edge portion 12b of the cooking dish 10 is located above the outer peripheral edge portion 9c of the rotating net 9, the outer peripheral edge portion 12b of the cooking dish 10 is rotated by the rotary net 9
Since it can be further distanced from the outer peripheral edge portion 9c and the necessary insulation distance can be secured further, generation of spark discharge during range heating using the metal cooking dish 10 can be more reliably eliminated. it can. Also, in this case, the rotating net 9
It is also possible to prevent the surface of the cooking dish 10 near the outer peripheral edge portion 12b from closely approaching the outer peripheral edge portion 9c, thereby preventing spark discharge from occurring.

Further, since the peripheral portion 9a of the rotary net 9 on which the cooking dish 10 is placed is formed in a continuous body, the rotary net 9 has a portion which can serve as an electrode at the contact portion thereof. As described above,
It is possible to more surely eliminate the occurrence of spark discharge when the range is heated using the metal cooking dish 10.

In this case, even if the base 12 which is a portion to be placed on the rotary net 9 of the cooking dish 10 is formed in a continuous body, there is a portion which can serve as an electrode in the cooking dish 10 at the contact portion thereof. As a result, the occurrence of spark discharge at the time of heating the range using the metal cooking dish 10 can be more surely eliminated.

In contrast to the above, FIG. 5 shows a second embodiment of the present invention. In addition to the structure of the first embodiment, the outer peripheral edge portion (outer edge portion of the peripheral portion 9a) 9c of the rotary net 9 is shown. Is shown inwardly curled. By doing so, the outer peripheral edge portion 12b of the cooking dish 10 can be further distanced from the outer peripheral edge portion 9c of the rotary net 9, and the necessary insulation distance can be further increased. Since a large amount can be secured, it is possible to more surely prevent the occurrence of spark discharge when the range is heated using the metal cooking dish 10.
