Description

TECHNICAL FIELD The present invention relates to a turntable for a high-frequency heating device.

2. Description of the Related Art In a high-frequency heating device equipped with a turntable, a roller stand that runs on the bottom wall of the heating chamber is provided as shown in Japanese Utility Model Publication No. 61-44795, and food is placed on the rollers of the roller stand. In addition to the one in which the saucer is placed and the food saucer runs directly on the roller, it is actually used
It is known to provide a roller stand that travels on the bottom wall of the heating chamber as shown in Japanese Patent Laid-Open Publication No. 1993-101, and place a food tray on a stand formed on the roller stand to rotate the food.

Problems to be Solved by the Invention In the case of the structure disclosed in Japanese Utility Model Publication No. 61-44795, the roller directly travels on the back surface of the food tray, so that the roller can be run smoothly. A smooth surface condition is required for the part of the back of the food tray that comes into contact with. For example, a glaze-coated metal plate such as enamel does not provide a sufficiently smooth surface, which causes noise and vibration during traveling. In order to avoid the noise and vibration, it is necessary to use a flat glass plate with a flat surface and smooth surface.

Means for Solving the Problems The present invention is provided with a metal roller base that lays on the bottom wall surface in a heating chamber, and at least three rollers are provided.
The roller stand is provided with an annular dish receiving surface on which the food tray made of enamel is placed, and the bottom surface of the food tray placed on this dish receiving surface is the circle formed on the roller stand. An annular convex ring is formed so as to smoothly surround the outer periphery of the annular dish receiving surface to facilitate the centering of the food dish when it is placed on the roller table, and thereby, the roller platform. The roller, the convex ring of the food tray, and the tray surface of the roller stand were positioned and arranged in the order described from the outer peripheral direction toward the center of rotation at the outermost peripheral position of the turntable.

Action As described above, the roller of the roller base, the convex ring of the food tray and the saucer surface of the roller base are arranged at the outermost peripheral position of the turntable and are positioned in the order described from the outer peripheral direction toward the center of rotation. In addition to the easy and reliable centering and placement of the food tray on the roller table, stable rotational traveling is performed even if the weight imbalance due to uneven distribution of the food on the food tray occurs.

Example The structure of this example is as shown in FIG.

In this embodiment, the wall surface of the bottom of the heating chamber is a flat heater, and a roller table for placing a turntable is run on the flat heater.

In FIG. 1, 1 is a heating chamber side wall and 2 is a heating chamber bottom wall. Reference numeral 3 is a flat heater attached to the back surface of the heating chamber bottom wall 2, and 4 is a metal plate provided for improving the degree of adhesion between the flat heater 3 and the heating chamber bottom wall 2 and having excellent thermal conductivity. It is a sheet of. A pressing plate 5 presses the flat heater 3 from the back side. Reference numeral 6 denotes a group of concentric ribs provided to maintain the flatness of the bottom surface of the heating chamber and to minimize the deformation of the bottom wall when the flat heater 3 generates heat. Reference numeral 7 denotes a roller base, which is made by punching a metal plate integrally, and is provided with three rollers at the outermost peripheral position so as to rotate on the bottom wall of the heating chamber. Reference numeral 8 denotes the roller, which is attached to the outermost side of the roller base as shown. Reference numeral 9 denotes a roller traveling surface which has a flat surface and is projected in an annular shape at a portion of the heating chamber bottom wall on which the roller 8 is traveling. Reference numeral 10 denotes a rotation driving motor for the roller base 7, the rotary shaft of which penetrates the bottom wall of the heating chamber and projects into the heating chamber, and is connected to an engaging portion at the center of the roller base. Although detailed description is omitted, the penetration portion of the motor drive shaft on the bottom wall of the heating chamber has a structure for preventing leakage of high frequency energy. Reference numeral 11 denotes an annular dish receiving surface that is formed by projecting upward at a certain distance from the roller 8 at a position close to the inside of the roller 8. A food plate made of a metal plate on which a porridge is applied is placed on the plate as described below. The surface to place. As can be seen from the drawing, the mounting surface is formed slightly higher than the roller. Reference numeral 12 is a food tray made of enamel and made of a metal plate, and is placed on the tray receiving surface 11 of the roller base 7. And, 13 is formed by projecting downward in an annular shape between the roller 8 and the plate receiving surface 11 on the back surface of the food tray 12, and a convex functioning for centering when it is placed on the roller stand. It is a ring.

In this way, the embodiment of the present invention realizes smooth rotation of the turntable because the roller 8 does not directly travel on the surface of the walnut. Further, the roller 8 of the roller base 7, the convex ring 13 on the back surface of the food tray 12 and the saucer surface 11 of the roller base 7 are arranged at the outermost peripheral position of the turntable and are described from the outer peripheral direction toward the center of rotation. Since they are positioned in order, not only easy and reliable centering and placement of the food tray 12 on the roller table 7 can be performed,
Even if there is an imbalance in weight due to uneven distribution of food on the food tray 12, stable rotational travel is performed. Further, even when the flat heater 3 attached to the bottom wall 2 of the heating chamber may be operating to generate heat, the roller 8 travels in the peripheral region where the temperature is relatively low, so that the heat of the main heat radiation surface may be taken away. Without this, excellent cooking is guaranteed without obstructing the space between the heat radiation surface and the food tray.

Effects of the Invention According to the present invention, it is possible to realize a turntable that rotates stably and quietly even if an inexpensive food saucer with a enamel-shaped metal plate is used instead of an expensive food saucer made of glass. It was
