  When the handle 50 is attached, if the lower end portion of the handle 50 is put on the outer side surface 41 a of the circular portion 41 from the outside, the small diameter shaft 52 is fitted into the long groove 44, and the handle boss 53 is a semicircular arc-shaped concave portion of the circular portion 41. 45.

  A state in which the handle boss 53 moves according to the rotation of the handle 50 will be described with reference to FIG. FIG. 11A shows a state in which the handle 50 that closes the lower hot plate H1 and the upper hot plate H2 is 0 degrees. In this state, the small-diameter shaft 52 is located at the lower end of the long groove 44, and the handle boss 53 is located obliquely above the large arc surface 45 a of the semicircular arc-shaped recess 45.

  Next, a state where the handle 50 is rotated 90 degrees is shown in FIG. In this state, the small-diameter shaft 52 is positioned at the lower end of the long groove 44, and the handle boss 53 is rotated clockwise in the drawing and is positioned below the large circular arc surface 45a of the semicircular arc-shaped recess 45.

  Next, a state where the handle 50 is rotated 120 degrees is shown in FIG. In this state, the small-diameter shaft 52 is located at the lower end of the long groove 44, and the handle boss 53 collides with the step 45 b of the semicircular arc-shaped recess 45. In this state, the upper hot plate H2 is prevented from further rotation with respect to the lower hot plate H1, and remains in that position.

  Therefore, it becomes easy to prepare the cooked food before the sandwich baking described later, or to take out the cooked food after the sandwich burning. The angle is not limited to 120 degrees, and any angle may be set as long as it is an obtuse angle.

  FIG. 11D shows a state where the unrotatable state is released. The figure shows a state in which the handle 50 is pulled up in the long axis direction of the long groove 44 as indicated by an arrow. When the handle 50 is lifted in the long axis direction of the long groove 44 in this way, the small diameter shaft 52 is positioned at the upper end of the long groove 44, and the handle boss 53 is positioned above the step portion 45b. It becomes possible.

  Next, a state where the handle 50 is rotated 180 degrees is shown in FIG. In this state, the small diameter shaft 52 is located at the lower end of the long groove 44, and the handle boss 53 is located above the small arc surface 45 c of the semicircular arc-shaped recess 45.

  Thus, the hot plate H is opened, and simultaneous cooking on the lower hot plate H1 and the upper hot plate H2 in the opened state is possible. When the hot plate H is closed, the handle boss 53 moves in the reverse direction within the semicircular arc-shaped recess 45.

  The slide lever 60 is shown in FIG. The slide lever 60 is a substantially linear and flat lever that enables parallel movement and rotation of the upper hot plate H2. A slide shaft 61 having a small diameter is attached to one end thereof, and a screw hole is provided on the other end. 62 is drilled.

  The slide shaft 61 is fitted into the slide groove 31a of the upper hot plate guard member 30 from the inside, and is attached from the outside by washers and screws (not shown). The screw hole 62 is attached to the screw attachment port 46 of the circular portion 41 with a screw 46a. In addition, the screw hole 26b of the L-shaped end portion 26a of the lower hot plate guard member 25 is also integrally attached to the screw mounting port 46 of the circular portion 41 by the screw 46a.

  That is, the screw hole 62 portion of the slide lever 60 is rotatably attached by the screw 46a, and the slide shaft 61 is slidably attached in the slide groove 31a.

  The opening operation of the hot plate H will be described with reference to FIGS. FIG. 3 shows the state of the handle 50 at 0 degrees with the lower hot plate H1 facing downward and the upper hot plate H2 closed. In this state, the slide shaft 61 of the slide lever 60 is located at the right end of the slide groove 31a.

  In this state, the handle 50 is lifted upward. Then, the large-diameter shaft 51 of the handle 50 tries to rotate the upper hot plate H2 with the bearing member 40 as an axis. The slide lever 60 is attached to the bearing member 40, and the slide lever 60 Since the slide shaft 61 at the tip moves from the left to the right in the slide groove 31a during rotation, the rear end side of the upper hot plate H2, that is, the slide groove 31a side is the tip side of the upper hot plate H2. That is, it rises similarly to the opposite side to the slide groove 31a side.

  The lengths of the slide groove 31a and the slide lever 60 are set so that the rise on the rear end side of the hot plate H2 and the rise on the front end side are the same. The angle may be 90 degrees or less, and in this example, the angle is set to around 45 degrees. That is, in this example, the upper hot plate H2 moves parallel to the lower hot plate H1 up to 45 degrees. Thereafter, the upper hot plate H2 rotates with respect to the lower hot plate H1, and the angle becomes 180 degrees as shown in FIG.

  Note that the angle at which the upper hot plate H2 is translated with respect to the lower hot plate H1 can be up to 90 degrees, for example, but at the time of translation, the upper hot plate H2 is moved to the lower hot plate as shown by the arrows in FIG. Since it moves parallel to H1 diagonally upward and the cookable area in which the grilling can be performed decreases as the angle increases, the vicinity of 45 degrees is set. The distance between the lower hot plate H1 and the upper hot plate H2 at an angle of 45 degrees of the handle 50 is about 5 cm. FIG. 4 shows a state where the handle 50 is lifted 45 degrees upward. In this state, the slide shaft 61 of the slide lever 60 has moved to the right end of the slide groove 31a.

  That is, in this example, a two-axis two-link type link mechanism is used, which has an advantage that the entire structure can be simplified. And it is possible to perform sandwich grilling according to the size of the food. When sandwiching is performed, the handle 50 is first lifted 120 degrees upward as shown in FIG. In this state, as described in FIG. 11C, the handle boss 53 of the handle 50 collides with the step 45b of the semicircular arc-shaped recess 45, and the upper hot plate H2 is more than the lower hot plate H1. Is prevented from rotating and remains in that position. Therefore, preparations such as arranging food on the lower plate 20 of the lower hot plate H1 become possible.

  When the preparation of the food is completed, the handle 50 is lifted and then returned to the direction in which the angle decreases. Then, the upper hot plate H2 approaches the lower hot plate H1 while rotating, and when the angle is within 45 degrees with respect to the lower hot plate H1, the upper hot plate H2 moves parallel to the lower hot plate H1. become.

  When the handle 50 is returned as it is, the upper plate 20 'of the upper hot plate H2 comes into contact with the upper surface of the food. When the cooked product is heated in this state, for example, sandwiching a thick cooked product can be performed. In this case, since the weight of the upper hot plate H2 is added from above the cooked food, the sandwiched grill is applied with pressure, and is particularly effective for cooking such as squid grill.

  By the way, in the above-described structure, the upper hot plate H2 is lowered by its own weight at the time of sandwich baking, and the cooked product is applied to that extent, so that the cooked product may be deformed. Therefore, for example, a commercially available damper with a free stop function may be interposed between the large-diameter shaft 51 of the handle 50 and the bearing opening 14. By adopting such a structure, it is possible to perform sandwich grilling where no force is applied, or double-side grilling having a space between the food and food, and convenience is further enhanced. Further, when setting the food, the upper hot plate H2 can be stopped at an angle at which it is easy to set. Furthermore, the upper hot plate H2 closes suddenly, and there is no possibility of pinching a hand or a finger.

  Of course, the hot plate H is further rotated from the state of FIG. 5 to an angle of 180 degrees, the hot plate H is opened, and simultaneous cooking on the lower hot plate H1 and the upper hot plate H2 is performed, that is, one side in a wider range. Cooking can also be performed.

  FIG. 13 shows an example of double-sided baking using the frame plate 70. The frame plate 70 is a cylindrical member having a rectangular shape or a circular shape in plan view, and has a height of 5 cm, for example. When the hot plate H is in the state shown in FIG. 5, the food is placed on the lower plate 20 of the lower hot plate H1, and the frame plate 70 is placed so that the food is inside. In this case, the height of the cooked food is lower than the height of the frame plate 70.

  Thereafter, the hot plate H is brought into the state shown in FIG. Then, the upper hot plate H2 is supported in contact with the upper surface of the frame plate 70. If it heats in that state, a double-sided baking or steaming cooking can be performed. In this case, there is a space between the upper surface of the cooked food and the upper plate 20 '. By using the frame plate 70 in this way, it becomes possible to perform simultaneous double-sided grilling of fish with no force applied from above and below, and the cooking menu is increased accordingly.

  The present invention is not limited to the configuration of the above-described embodiment, and can be appropriately changed in design without departing from the gist of the invention.
