Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a high-frequency heating device, and more particularly to a so-called turntable device on which an object to be heated is placed and rotated.

Configuration of conventional example and its problems Hereinafter, a conventional high frequency heating device will be described with reference to the drawings.

FIG. 1 shows a partially cutaway front view of a conventional high-frequency heating device. and a magnetron 4 that supplies high frequency waves to the heating chamber 2. FIG. 2 shows a side cross-sectional view of the same high-frequency heating device. Inside the heating chamber 2, there is a rotating saucer 5 on which the object to be heated is placed. A motor 7 for rotating the saucer 5 is provided. A roller section 8 is composed of a plurality of rollers 8a and a ring-shaped roller support 8b, on which the tray 5 is placed and rotates as the tray 5 rotates. Further, on the bottom surface of the heating chamber 2, a constriction portion 9 for positionally regulating the rotation of the roller 8a is provided in a convex manner toward the outside of the heating chamber. 10 is a protective cover for the motor 7, and 11 is a leg of the main body of the high-frequency heating device 1.

According to this configuration, since the constriction part 9 and the protective cover 10 protrude from the bottom of the main body, the leg part 11 must be made high, which results in an increase in the height of the main body of the device and significantly impairs the appearance. This has the disadvantage that the packaging volume is large and the logistics costs are also high. In addition, the peripheral edge of the saucer 5 is connected to the heating chamber 2.
Since the tray 5 is located at a lower position than the upper end of the lower peripheral edge of the front opening, it is difficult to take out the saucer 5, making it inconvenient to use.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and aims to provide a compact and easy-to-use high-frequency heating device.

Structure of the Invention In order to achieve this object, the high-frequency heating device of the present invention is small and easy to use, by providing a constriction part on the bottom surface of the heating chamber that protrudes toward the inside of the heating chamber, and a part of the motor is accommodated in this constriction part. This provides a high-frequency heating device with good quality.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the drawings.

FIG. 3 is a partially cutaway front view of a high-frequency heating device showing an embodiment of the present invention.
2 is a heating chamber 13 that stores and heats the object to be heated; a door 14 that can be opened and closed at the front opening of the heating chamber 13;
A magnetron 15 that supplies high frequency to the heating chamber 13
It has FIG. 4 shows a side sectional view of the same high-frequency heating device. Inside the heating chamber 13, there is a rotating saucer 16 on which the object to be heated is placed. A motor 18 for rotating the saucer 16 is provided. A roller section 19 is composed of a plurality of rollers 19a and a ring-shaped roller support 19b, on which the tray 16 is placed and rotates as the tray 16 rotates. Further, on the bottom surface of the heating chamber 13, a constriction part 20 is provided inside the roller part 19 to restrict the position of the rotation of the roller 19a so as to protrude toward the inside of the heating chamber. A portion of the motor 18 is housed within the constriction section 20 at the outside bottom of the heating chamber. Further, the peripheral edge of the saucer 16 is disposed at a higher position than the upper end of the lower peripheral edge 21 of the front opening of the heating chamber 13 . 22
23 is a motor protection cover, and 23 is a leg portion of the main body of the high-frequency heating device 1.

According to this configuration, the aperture section 20 is arranged in the heating chamber 1.
3 is convex inward, and the motor 18 is accommodated in the constriction part 20 at the outside bottom of the heating chamber, so that the protrusion of the lower part of the main body of the high-frequency heating device 1 can be reduced, and the leg part 23
Since the height of the device can be lowered, the height of the device body can also be lowered, allowing for miniaturization. Further, since the peripheral edge of the saucer 16 is disposed at a higher position than the upper end of the lower peripheral edge 21 of the front opening of the heating chamber 13, the saucer 16 can be easily taken out, improving usability.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) Since the protrusion at the bottom of the high-frequency heating device main body can be kept low, the legs can also be made low, and as a result, the height of the device main body can be reduced.

(2) As mentioned above, the protruding dimension of the bottom of the device main body is reduced, and since there is no protruding part that spoils the appearance, the product quality can be improved.

(3) As mentioned above, the device itself can be made smaller;
The packaging volume is also smaller, which reduces logistics costs.

(4) The saucer can be taken out easily, improving usability.
