a) is provided with a protrusion (9c), a shaft (9d) is provided on the central upper surface of the protrusion, and the shaft (9d) supports one end of the handle (11), and the handle (11) is moved to a frying pan (9). It is provided rotatably in the standing direction from the state extending in the same direction as the horizontal plane of 9). Frying pan (9) when lifting the handle (11)
The frying pan (9) keeps its horizontal state because the end of the convex portion (9c) (9e) comes into contact with the lower part of the handle (11) due to its own weight acting to lower downward. . With these configurations, when cooking with a stove, the handle (11) is made substantially horizontal, and the high-frequency cooking apparatus body (1)
When cooking inside, if the handle (11) is folded in the upright direction to accommodate the frying pan (9), there is no lateral protrusion of the handle (11) and the heating surface (9b) of the frying pan (9). It is possible to provide the maximum amount of space and to move the handle (11) in the upright direction by the shaft (9d). It's not annoying. Further, as shown in FIG. 5, a shaft (9f) is provided on the outer side (9a) of the frying pan (9), and one end of the handle (11) is supported by this shaft (9f). The handle (11) is provided with a concave arc surface (11a) so as to follow the convex arc surface of the frying pan (9). The shaft (9f) rotatably supports the handle (11) in the same plane as the horizontal plane of the frying pan (9).

When cooking inside the high-frequency cooking device body (1), the concave arc part (11a) of the handle (11) is placed along the convex arc surface of the outside (9a) of the frying pan (9) and stored. The protrusion of the handle (11) is only the width of the handle, and the heating surface of the frying pan (9) can be made large.

Also, when cooking with a stove, rotate the handle (11) away from the outside (9a) of the frying pan (9),
Fix at a position orthogonal to the tangent line. Since the handle (11) has an arcuate portion (11a), it fits well in the hand and good operation is possible.

Further, if the handle (11) is provided with a member that is difficult to be heated by high frequency, such as tetrafluoroethylene, polypropylene, polysulfone, etc., the handle (11) can be prevented from being heated and it can be easily grasped with bare hands, which is convenient.

Further, as shown in FIG. 6, if a frying pan (9) is provided with a member (12) made of glass, pottery, porcelain or the like for transmitting high frequency, oil in the refrigerator, food to be cooked (6)
Can be prevented from scattering and the heating efficiency can be improved.

If the outer surface of the frying pan (9) is coated with a member that absorbs high frequency and generates heat, such as ferrite powder, the frying pan (9) can efficiently absorb the high frequency energy and shorten the cooking time.

When the frying pan (9) is made of an aluminum alloy, the inner surface of the frying pan (9) is hard to be heated by microwaves and is coated with a member that prevents the cooking target (6) from adhering, for example, a fluororesin or the like. ) Does not adhere to the frying pan (9) to improve the cleanability, and the microwave does not overheat the frying pan (9), so that excessive burn-in can be prevented.

As shown in FIG. 7, the rotary shaft (10) of the rotary plate (10)
A disk (13) is installed orthogonally to a), and the disk (1
An elliptical opening (13a) is opened at the edge of 3), a light emitting element (14) and a light receiving element (15) sandwiching the opening (13a) from above and below are provided, and an input is received from this light receiving element (15). The control means (16) for controlling the operation of the electric motor (7) is provided, and when cooking is started in the step (17) as shown in the flowchart of FIG. 8, the disk (13) is rotated by the rotation of the electric motor (7).
Rotates. The disc (13) rotates in synchronization with the frying pan (9) in the heating chamber (2), and for example, about 10 times per rotation.
Takes seconds. Further, since the opening (13a) is located at the edge of the disc (13), the opening (13a) rotates. When the opening (13a) comes between the light emitting element (14) and the light receiving element (15), the light receiving element (15) receives the light of the light emitting element (14) (step (18)). When the light receiving element (15) receives the light received, the control means (1
6) detects the remaining cooking time, and when the remaining cooking time is 10 seconds or more in step (19), the process proceeds to step (20) and the electric motor (7).
Continue driving. When the remaining cooking time is less than 10 seconds, the process proceeds to step (21) to stop the electric motor (7) instantaneously. According to this structure, the position of the handle (11) at the start of cooking and the end of cooking or the predetermined position of the frying pan are at the same position, and the frying pan (9) can be easily taken out at the end of cooking.

In the embodiment shown in FIGS. 7 and 8, light emission,
Although the rotation of the frying pan (9) is controlled using the light receiving element, the rotation may be controlled by a magnet relay or a mechanical structure, and the method is not limited to this.

Further, when cooking is performed by a high-frequency heating cooking apparatus equipped with an electric motor (7) for rotating a rotating plate (10) supporting the frying pan (9) from below, as shown in FIGS. ) Has a plurality of frying pan ribs (22) concentrically formed on its outer bottom surface, and at least one of the frying pan ribs (22) engages with a rib (10a) on the peripheral edge of the rotating plate (10). With this arrangement, the frying pan (9) can be supported on the rotary plate (10) at a predetermined position at all times, and malfunctions such as sliding down from the rotary plate (10) can be prevented. Furthermore, when cooking with this frying pan (9) on a stove, multiple frying pan ribs (22) are supported by Gotoku, as shown in FIG. 11, so even when placed on Gotoku of various sizes, it rattles. It is possible to mount it horizontally without any problems.

The frying pan rib (22) also reinforces the frying pan (9). The other frying pan ribs (22) have the same height as the frying pan ribs (22) on the rotating plate (10).
If the frying pan ribs (22) are connected together, the number of frying pan ribs (22) may be one, but since the plate thickness becomes thick and heavy, it is better to provide a plurality of frying pan ribs (22) for better operability.

In addition, providing a plurality of frying pan ribs (22) also increases the area of the outer bottom surface of the frying pan (9), and has the effect of improving the heat absorption from the stove.

In the case of the circular rotary plate (10), the frying pan (9) and the rotary plate (9) and the rotary plate ( Although there is less rattling with the frying pan 10), the circumference of the frying pan rib (22) is closer, so the rotating plate (10) engages the frying pan rib (22) next to the regular engaging position. There is a problem that it will be supported while tilted. Further, when the frying pan ribs (22) are brought close to each other, a large number of inner frying pan ribs (22) must also be formed at equal intervals. This is to prevent the strength of the bottom surface of the frying pan (9) from fluctuating and easily causing thermal deformation.
Becomes heavy. Therefore, as shown in FIGS. 12 and 13, the rotating plate rib (10a), which is the contact surface of the rotating plate (10) with the frying pan (9), is formed into an elliptical shape.
The frying pan (9) is formed with a great circle frying pan rib (22a) so as to engage with the outer side on the major axis (10b) side of the rotating plate rib (10a) on the rectangular (10c) side inner side. If the small circular frying pan rib (22b) is formed on the outer bottom surface of the frying pan (9) as described above, rattling between the rotary plate (10) and the frying pan (9) is reduced and the frying pan rib (2) is formed.
The space of 2) can be widened, and the frying pan ribs (22) following it can be provided at a wide space, and the frying pan (9) does not become heavy.

The interval between the frying pan ribs (22) can be changed by arbitrarily changing the ratio of the major axis (10b) and the minor axis (10c) of the ellipse.

Further, since the rotating plate (10) has an elliptical shape, the material cost can be reduced.

Figure 14 shows the state of being placed on the stove. The rotary plate (10) shown in FIG. 13 has an elliptical shape, but may have an oval shape.
As shown in FIGS. 15 and 16, a substantially trapezoidal heat-resistant guide wall (23) is provided over the end (2c) on the front surface (2b) side of the heating chamber (2). If the first inclined surface (23a) is provided on the inner front surface of 23) and the outer side of the frying pan (9) is applied to guide the frying pan (9) into the heating chamber (2), the frying pan (9) will come out. When putting it in, the outside of the frying pan (9) does not hit other parts,
It is possible to prevent deformation and punching of the main body (1) of the high-frequency heating / cooking device. When taking out the frying pan (9), the second inclined surface (23b) guides the frying pan (9).

If the guide wall (23) is elastically supported on the side surface of the heating chamber (2) by a spring, the frying pan (9) will move to the guide wall (2).
Since the shock when hitting 3) can be buffered, the operability is further improved.

 The guide wall (23) may be semicircular.

In the case of a high frequency cooking device without a rotating plate (10),
As shown in FIGS. 17 and 18, the heating chamber (2) is provided with a recess to provide a handle storage chamber (2a), and if the handle (11) is stored therein, the long handle (11) will become a frying pan (9). ), And since the handle (11) is located in the recessed handle storage chamber (2a), it has the effect of preventing microwaves from reaching and heating. Further, as shown in FIG. 19, a shaft (9g) is provided on the outer side (9a) of the frying pan (9), and a handle (11) is attached to the shaft (9g) on the heating surface (9) of the frying pan (9).
If the frying pan (9) is housed in the heating chamber (2) if it is supported rotatably in the horizontal direction with respect to b), the handle (11) is arranged horizontally with respect to the front of the inside of the vessel (see the same figure). Since the middle arrow) can be provided, the handle storage chamber (2a) can be made small and the loss space can be reduced.

In addition, the shaft (9
A), the shaft (9f), and the shaft (9g) are all strongly gripped so that the grip (11) does not move unless a specified external force is applied.
And the frying pan (9) are pressed and supported.

[Effects of the Invention] As described above, according to the present invention, an object to be cooked is placed on a frying pan coated with a member that is hard to be heated by a high frequency and has a member that absorbs the high frequency and generates heat. A frying pan for cooking in the high-frequency heating cooking device is provided so that cooking can be performed in the cooking device, and the heating chamber formed in the high-frequency heating cooking device is recessed to form a handle storage portion for the frying pan. The long handle can be stored in the cabinet and the operation of taking in and out the frying pan is also easy.

Also, when the frying pan coated with a member that is hard to be heated by high frequency and whose outer surface absorbs the high frequency and generates heat is put in and out of the high frequency cooking device body, the guide wall provided in the heating chamber makes the outside of the frying pan abut. Prevents deformation and hammering of the high-frequency cooking device body.

Also, because multiple ribs are provided on the outer bottom of the frying pan,
There is no rattling when placed on a rotating plate or stove, and thermal efficiency is improved on the stove.

Further, since the handle of the frying pan or a predetermined portion of the frying pan is always stopped at various positions when the cooking is completed in the main body of the high-frequency heating cooking apparatus, the frying pan can be easily taken out.
