Description

[Detailed Description of the Invention] The present invention relates to a cooking device such as an electric oven or a high-frequency heating device, and its purpose is to provide a cooking device that can cook food well and is easy to use. There is a particular thing.

In order to achieve this object, the present invention magnetically connects a rotary mounting table rotatably provided on the bottom plate of the heating chamber and a rotating body provided under the bottom plate of the heating chamber opposite to this rotating mounting table. They are coupled by attraction or magnetic repulsion, and the rotary mounting table is moved in and out of the heating chamber in conjunction with the opening and closing of the door.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

FIG. 1 shows an embodiment in which the present invention is applied to a high-frequency heating device. As shown in FIG. A power supply port 6 coupled to a magnetron 4 as a device by a waveguide 5 is provided, and high-frequency electromagnetic waves are supplied into the heating chamber 2 from the power supply port 6 .

On the other hand, a door 7 is provided in the front opening of the heating chamber 2 so as to be openable and closable.
A rail 8 is fixed to the lower part of the rail 8, and this rail 8 with moving rollers 10 moves back and forth along with the door 7 on fixed rollers 9, and the door 7 is opened and closed.

In addition, a rotating mounting table 1 is provided on the surface of the door 7 facing the inside of the heating chamber 2.
A holder 12 that supports 1 is fixed.

As shown in FIG. 2, the holding structure of the rotary mounting table 11 is such that the hooks 14 a and 14 b of the support 14 are hooked onto rods 13 a and 13 b at both ends of a support 130 formed of metal rods.

A roller shaft 15 integrally formed with the support 14
After inserting the roller 16 into the
I'm trying to keep 6 from coming off.

The rotary mounting table 11 having a roller groove 18 formed on its peripheral edge is placed on the roller 16 .

The mounting structure of the holder 12 fixed to the door 7 of the support 13 is as shown in FIGS. The hook 13d of the support 13 is held against the holder 12.

On the other hand, two rollers R (see FIG. 4 for the pivot position of the rollers R) are supported on the rear end rod 13b forming the support 13, and these rollers R1 and the holder The support 13 is supported by 12 at the front and rear.

Therefore, the holder 12 is extremely susceptible to strong deformation, and will not bend downward due to the loads of the rotary mounting table 11, the object to be heated 19, the saucer 20, etc.

Note that when removing the support 13 from the holder 12, the support 1
This can be easily done by lifting the rear part of 3 in the direction of the arrow in Figure 3.

Next, the structure for rotating the rotary mounting table 11 will be described.

That is, a rotating body 22 to which a plurality of magnets 21 are attached is rotatably supported under the bottom plate of the heating chamber 2 around a shaft 23 .

Further, this rotating body 22 is provided with a roller 24 so that the magnet 21 is placed as close to the bottom plate of the heating chamber 2 as possible so as to rotate smoothly.
A belt groove 25 is formed in the circumference of this rotating body 220, and the rotating body 27 fixed to a motor 26 is connected to the rotating body 27 by a belt.

Therefore, when the motor 26 rotates, the rotating body 22 to which the magnet 21 is attached rotates at a constant reduction ratio.

On the other hand, a magnet 28 is mounted on the rotary mounting table 11 at a position facing the magnet 21, and the bottom plate of the heating chamber 2 and the mounting bracket 29 of the magnet 28 are made of a non-ferromagnetic material so as not to weaken the magnetic force. Therefore, the magnets 21 and 28 attract each other, and as a result, as the rotating body 220 rotates, the rotating mounting table 1
1 rotates.

Note that when the door 7 is closed, the center of the rotary mounting table 11 and the center of the shaft 23 under the bottom plate of the heating chamber 2 are made to substantially coincide, so that the magnetic force is efficiently transmitted to the rotary mounting table 11. Rotates smoothly.

According to the above configuration, the food 19 rotates together with the rotary mounting table 11, so even if the electric field distribution (heat distribution in the case of an oven) in the heating chamber 2 becomes uneven, uneven heating of the food 19 will not occur. do not have.

In addition, when the door 7 is opened, the food 19 comes out of the heating chamber 2 together with the rotary mounting table 11, so there is no need to put your hand inside the heating chamber 2 to take out the food 19, making it extremely convenient and convenient to use. .

FIGS. 4 and 5 show another embodiment of the present invention, in which a shaft 30a with semicylindrical apertures is provided at key points of a metal plate 30, and then a circular notch is formed in the center. .

σ) The roller 16 is fitted into the shaft 30a and rotatably supported, and as in the above embodiment, the support tool 1
The trouble of fixing the roller shaft 15 to the roller shaft 15 can be saved.

6 and 7 show still another embodiment of the present invention, in which a metal plate 30 is provided with an annular groove 31, in which the roller 16 rotates. .

Therefore, the rotational torque of the roller 16 can be reduced, and accordingly, the motor 26 and the roller 16 can be made smaller, and the heating chamber 2 can be made larger.

In this case, it is necessary to provide a frame for positioning the roller 16.

As described above, according to the present invention, the object to be heated is rotated by the rotary mounting table, so even if the electric field distribution in the heating chamber (in the case of a high-frequency heating device) or the thermal atmosphere (in the case of an electric oven, etc.) is uneven, There is no uneven heating of the object to be heated.

In addition, as the rotating mounting table comes out of the heating chamber with the object to be heated in conjunction with the opening and closing of the door, there is no need to manually reach into the heating chamber to take out the object to be heated. As a result, there is no need to turn the heated object over when it is taken out, making it extremely convenient to use.
