Description

[Detailed description of the invention] This invention is a microwave oven that heats foods, etc. using high frequency waves, especially a microwave oven that has a removably arranged turntable for the purpose of actively eliminating uneven heating. It is related to the specific structure of.

An embodiment of this invention will be described below.

Reference numeral 1 designates a high-frequency heating chamber, and a rotary member 4 supported by a bearing 3 is located in a recess 2 at the bottom of the chamber 1, and the rotational force of a drive motor 5 is transmitted to the rotary member 4 via a deceleration mechanism 6.

Reference numeral 7 denotes a turntable that fits into the bottom recess 2 of the heating chamber 1 and rotates with the food to be cooked placed thereon, and the bottom surface of the table is provided with an engaging claw 7a that engages with the engaging recess 4a of the rotating member 4. is formed.

Furthermore, this turntable 7 and the bottom wall 2 of the recess 2 of the heating chamber 1
a to prevent the turntable 7 from tilting,
three or more rollers 8 that rotatably support the table;
A roller support ring 9 having rollers 8.8 attached at equal intervals is arranged.

A turntable 7 is attached to the outer edge of this roller support ring 9.
A plurality of fitting protrusions 11, 11, 11 are protruded at equal intervals to fit into the annular groove 7b formed on the outer periphery of the bottom surface.
The roller support ring 9 is removably attached to the bottom surface of the turntable 7 by means of the fitting protrusions 11, 11, 11.

In this case, the protrusion 11 serves as the first fitting part, and the annular groove 7b serves as the second fitting part.
The turntable 7 and the roller support ring 9 are integrated when the two bottoms are press-fitted, and the turntable and the roller support ring are separated from each other when they are not fitted. .

lla is a guide rib provided hanging down from the fitting protrusion 11, and its lower end descends toward the center of the ring 9.

Reference numeral 12 designates another protrusion formed to protrude from the ring 9, and this serves as a spacer between the ring 9 and the bottom recess 2.

Note that each protrusion and rib 11, 12 . lla is integrally molded from synthetic resin such as polycarbonate.

10 is a support shaft that supports the roller 8; 13 is a magnetron; 14 is a blower; 115 is a high-voltage transformer; and 16 is a frame.

Then, the fitting protrusion 11 of the roller support ring 9 is fitted into the annular groove 7b on the outer periphery of the bottom surface of the turntable 7, and the ring 9 is removed.
is attached to the bottom of the turntable 7, and then the turntable 7 is placed in the bottom recess 2 of the heating chamber 1, and the engaging claw 7a of the turntable 7 is inserted into the engaging recess 4a of the rotating member 4. Engage and tighten.

At this time, the turntable 7 integrated with the ring 9
If the turntable 7 is placed slightly apart from the bottom recess 2, the lower end of the guide rib lla comes into contact with the peripheral layer 2b of the bottom recess 2 and slides downward, so the turntable 7 is guided toward the center of the bottom recess 2. Therefore, the mutual engagement between the engaging claw 7a and the engaging recess 4a is facilitated.

On the other hand, when cleaning the inside of the heating chamber 1, the turntable 7 is simply lifted and taken out from the heating chamber 1, and the roller support ring 9 is also taken out at the same time. There are no rollers or the like that get in the way of the work, making the work easy.

Further, in order to clean only the turntable 7 itself, the ring 9 can be easily separated from the turntable 7 by releasing the engagement between the turntable 7 and the ring 9 which have been taken out as described above.

As is clear from the above explanation, according to the present invention, both the turntable and the roller support ring that supports it rotatably without tilting can be completely removed from the heating chamber, making it easy to clean the inside of the heating chamber. Since the turntable and roller support ring are integral and detachable, it is easy to take the turntable and roller support ring in and out of the heating chamber, and if necessary, remove the roller support ring from the turntable. It can be removed to easily clean the entire turntable.
