Description

[Detailed Description of the Invention] The present invention relates to a high-frequency heating device, and particularly to a stand that is removably installed in a heating chamber of the high-frequency heating device, and its purpose is to provide a stand that is highly stable.

Conventionally, a stand has been removably provided in the heating chamber of a high-frequency heating device, but the devices that have been put into practical use to date have the following drawbacks.

In other words, in the conventional system, a plurality of legs made of wire rods extend downward from the peripheral edge of the stand, and a leg made of an insulator is attached to the tip of the legs, but each leg has one leg. It had only a downward extension, the lower end of which was wrapped around a groove in the outer circumference of the leg.

However, if there is only one downward extension and its lower end is wrapped around the groove as described above, each downward extension will deform in different directions, resulting in
The height of each leg was inconsistent, resulting in poor stability.

In addition, if there is only one downward extension and the lower end is wrapped around the leg, a metal end face will be formed at the part where it is wrapped around the leg, making it easy to generate sparks, and this spark will cause the leg to Sometimes it would break.

Therefore, the present invention attempts to eliminate the above-mentioned drawbacks of the conventional art by providing two downward extensions.

An embodiment of the present invention will be described below based on bath drawings.

In Fig. 1, 1 is the main body case, and this main case 1
An operation panel 2 is provided on the front right side of the main body case 1, and a heating chamber 3 is provided inside the main body case 1.
Furthermore, a door 5 equipped with a door screen 4 is provided in the front of the heating chamber 3 so as to be openable and closable.

A heater (not shown) is provided above the heating chamber 3, and high-frequency electromagnetic waves are supplied into the heating chamber 3 from a high-frequency oscillator (not shown).

That is, in this embodiment, the food to be cooked is heated by a heater and dielectrically heated by high frequency electromagnetic waves.

FIGS. 2 and 3 show accessory parts removably provided in the heating chamber 3. FIG.

That is, as shown in FIG. 2, a circular recess 7 is provided in the bottom wall 6 of the heating chamber 3 by pressing, and a disc-shaped rotary plate 8 is rotatably provided within this recess 7. .

Here, to briefly explain the rotational driving operation of this rotary plate 8, although not particularly shown, a plurality of permanent magnets are arranged in a circular manner on the lower surface of this rotary plate 8, while on the bottom part 6. A rotary drive plate equipped with a plurality of permanent magnets is provided below, facing the above-mentioned permanent magnets, and by rotating this rotary drive plate, the rotary plate 8 is rotated by magnetic coupling (for example, attractive force) between both of the above-mentioned permanent magnets. It is designed to rotate.

In addition, in order to obtain magnetic coupling between the two permanent magnets, the bottom wall 6 is
In other words, stainless steel 5US3 is used to allow the magnetic flux to pass through.
It is made of a non-magnetic material such as 04.

Next, in FIG. 2, 9 is a support roller of the rotary plate 8;
is a first saucer having legs 11 on the bottom surface.

Reference numeral 12 denotes a nearly circular metal wire stand as shown in FIG. is attached.

Reference numeral 15 denotes a second circular metal saucer, which is placed on the top surface of the stand 12 and
The positioning is performed by three metal positioning bodies 16 fixed by welding to.

In the above configuration, in this embodiment, as shown in FIG.
2 is formed from a plurality of wire rods.

Each of the three legs 13 provided on the peripheral edge has two downward extensions 13a, 13b, and the lower ends of these two lower blade extensions 13a, 13b have a partially open circular engagement. The open ends of the joining portions 13c are connected.

In this embodiment, the lower blade extensions 13a, 13b and the engaging portion 13c are integrally formed of a single wire rod.

A groove 14a provided on the outer periphery of the leg 14 is fitted into the engaging portion 13c with a slight play as shown in FIGS. 4a-c.

As described above, according to the present invention, since two lower blade extensions are provided, each leg does not deform in different directions of force, and therefore the height of the legs does not vary, making the stand stable. becomes.

Therefore, when a saucer is placed on this stand, it will not wobble and be turned over during cooking or the like.

Furthermore, since the lower ends of the two downward extensions and the open end of the engaging portion are connected, no metal end surface is formed in the leg portion, and therefore, there is no chance of sparks occurring here and causing the leg to break.

Furthermore, since there is some play between the retaining part and the legs, the legs will not break due to differences in thermal expansion coefficients.
