It is preferable that this circular member 21 is formed in part or in whole from a transparent material. In addition, in this type of heating cooker, since the diameter of the pot is generally not more than 27 cm, the inner diameter of the circular member 21 is about 27 cm. In addition, (22) (refer FIG. 2) is the inclination part provided in the upper inner peripheral surface of the circular member 21 in order to make it easy to insert a pot.

Reference numeral 23 is a connecting portion integrally provided at the lower portion of the circular member 21, and the fitting portion 24 is provided at the distal end portion with a narrow width, and the fitting portion 24 is provided with the through hole 25.

It is inserted and held in the holding hole 16 provided in (2).

The guide member 20 inserts the fitting portion 24 of the connecting portion 23 between the arm portions 36 of the supporting member 35, and passes through a support shaft 39, such as a split pin, for example. 38 and 25 are detachably inserted and connected to each other, whereby the circular member 21 is supported by the support member 35 so as to be rotatable with the support shaft 39 as the axis. The state at this time is shown in FIG. In addition, 17 is a stopper which protrudes from the top plate support frame 2 in the back side of the holding hole 16, and prevents the guide member 20 from falling to the back.

Next, the operation of the present embodiment configured as described above will be described.

When the heating cooker is not in use, the guide member 20 is rotated to the rear with the support shaft 39 as the axis, and provided on the support member 35 as shown on the left side of FIG. At this time, since the connection part 23 contacts the stopper 17, it does not fall back further.

Close to 3) and placed on the outer circumference of the circular line (4). At this time, if the circular member 21 is formed of a transparent material, it is easy to find out when foreign matter is present between the upper plate 3 and the circular member 21 is brought into close contact with the upper plate 3 by removing it. You can.

Then, as shown in Fig. 5, the pot 40 containing the workpiece is set in the circular member 21, and the bottom portion thereof is mounted on the circular line 4 of the upper plate 3. Thereby, the pan 40 can be reliably set in the predetermined position on the circular line 4. At this time, even if the circular line 4 is erased (disappeared), the pot 40 can be reliably mounted by the circular member 21 in a predetermined position. Next, the cooking temperature is set by the temperature adjusting knob 11, the power switch 10 is turned on, the heating element 14 is energized, the pot 40 is heated, the cooked material is heated, and cooking is performed. During cooking, the temperature display part 5 displays the temperature state at that time.

When the cooking is finished, the guide member 20 is rotated and prepared to stand on the rear side. As a result, the upper surface of the upper plate 3 is widened, and cleaning is easy. In addition, when cleaning the guide member 20, the support pin 39 may be pulled out to separate the circular member 21 from the support member 35, and in some cases, the circular member 21 is supported. The member 35 may be taken out of the holding hole 16. As a result, the guide member 20 can be easily cleaned. The state at this time is shown in FIG.

The pot 40 used for cooking may be an exclusive one or a commercially available one. However, when the heating element 40 is an electromagnetic induction coil, it is necessary to use a pot made of a magnetic material.

In addition, when setting the pot 40, if the thickness of the circular member 21 of the guide member 20 is extremely thin, the pan 40 will be caught on the circular member 21, and the bottom of the pot will be in close contact with the top plate 3. Not only does the heating efficiency deteriorate, but also heating unevenness occurs.

In order to avoid such an unreasonable problem, the thickness t of the circular member 21 (Fig. 5) can be set in the circular member 21 to ensure that the pot 40 can be secured and not move. It is necessary to thicken it, and it is preferable to set it to about 10 mm or more, for example.
