Description

[Detailed Description of the Invention] This invention relates to a high-frequency heating device for cooking foods and the like.

The purpose of this invention is to provide a plurality of rotating shelves in the high-frequency heating chamber, and by rotating these rotating shelves, it is possible to uniformly heat the object to be heated, and to effectively heat the inside of the high-frequency heating chamber. The purpose is to provide a high-frequency heating device that can be used for

Hereinafter, this invention will be explained based on one embodiment shown in the drawings.

In the figure, 1 is the main body, and inside this main body 1 is a high-frequency heating chamber 2.
A door body 3 is pivotally connected to the front opening so as to be openable and closable.

A high-frequency oscillator 4 made of a magnetron is provided on the ceiling 2a of the high-frequency heating chamber 2.

Further, a plurality of support rollers 6 are attached to the inner bottom 5 of the high-frequency heating chamber 2, and a disk-shaped lower rotary shelf 7 is rotatably mounted on the upper part of the support rollers 6.

A gear portion 8 is provided on the outer peripheral surface of this rotary shelf 7.

Further, a support plate 9 is horizontally attached above the rotating shelf 7, and a plurality of support rollers 10...
is installed.

An upper rotary shelf 11 is rotatably placed on top of these support rollers 10.

A gear portion 12 is provided on the outer peripheral surface of the rotary shelf 11.

On the other hand, a two-axis electric motor 13 is mounted on the mounting plate 1 at the back of the main body 1, that is, in the gap between the main body 1 and the high-frequency heating chamber 2.
It is attached by 4.

Gears 16a, 16b are attached to the tips of rotating shafts 15a, 15b of this electric motor 13.
, 16b is a through hole 1 bored in the back plate of the high frequency heating chamber 2.
It protrudes into the high frequency heating chamber 2 from 7ai7b.

One gear 16a meshes with the gear part 8 of the lower rotary shelf 7, and the other gear 16b meshes with the gear part 8 of the lower rotary shelf 7.
It meshes with the gear part 12 of No. 1.

Thus, when heating the objects a, a placed on the lower and upper rotary shelves 7, 11, the electric motor 13 is energized and the high frequency oscillator 4 is oscillated.

When the electric motor 13 operates, the rotating shafts 15a and 15b rotate, and the lower rotary shelf 7 and the upper rotary shelf 11 rotate in the same direction at a constant speed via the gears 16a and 16b.

Therefore, the objects to be heated a, a placed on these rotating shelves 7, 11 are heated and cooked while rotating.

In addition, in the above embodiment, two levels of rotating shelves were provided, upper and lower, but three or four levels may be provided depending on the oven capacity.
Alternatively, by making the diameter of the upper rotary shelf smaller than the diameter of the lower rotary shelf, the radio waves are not cut off by the rotary shelf and heating can be performed efficiently.

Furthermore, although a two-axis electric motor is used and the two rotating shelves are driven by the same drive source, the upper and lower rotating shelves may be driven separately.

Furthermore, the upper and lower rotating shelves may be rotated in different directions and may be rotated at different speeds.

As explained above, this device supports multiple stages of rotating shelves within the high-frequency heating chamber and drives these rotating shelves to rotate, so that it is possible to uniformly heat the object to be heated, and also to heat the inside of the high-frequency heating chamber. It can be used effectively.

Furthermore, since the electric motor that rotates the rotary shelf is installed in the gap between the main body and the high-frequency heating chamber, the space in the high-frequency heating chamber is not narrowed, and the drive is transmitted from the outer peripheral surface of the rotary shelf. Therefore, food can be placed at any position on the rotating shelf.
