Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the operability and space-saving structure of cooking utensils used in general households.

Conventional Structure and Problems Conventionally, in this type of cooking utensil, as shown in FIG. A cast-in heater 3 is fixed to the bottom upper surface of the inner frame 2, and a bottomed cylindrical pot 4 with a substantially circular cross section is removably placed on the upper surface of the cast-in heater 3. A hinge part 5 is provided at the upper end of the side, a circular outer cover 6 that covers the upper opening of the main body is rotatably supported on the hinge part 5, and a hook part 7 is provided at the upper end of the main body opposite to the hinge part 5. A lower frame 8 with legs that locks the main body and the outer cover 6 and covers the lower opening of the outer frame 1, or an outer frame 11 with a substantially rectangular cross section as shown in FIG. A main body is provided with a bottomed cylindrical inner frame 12 having a substantially rectangular cross section, and a cast-in heater 13 is fixed to the bottom upper surface of the inner frame 12.
A cylindrical pot with a bottom and a substantially square cross section that can be attached and detached to the top surface of the pot 1
A hinge part 15 is provided at the center upper end of one square side of the main body, and an outer cover 16 that rotatably covers the top opening of the main body is pivotally supported on the hinge part 15 and faces the hinge part 15. Generally, a hook portion 17 is provided at the upper center of one square side of the main body to lock the main body and the outer lid 16, and a lower frame 18 with legs is provided to cover the lower opening of the outer frame 11.

However, with this configuration, in the case of a circular inner frame-circular pot type (Fig. 1), when taking out the food in the pot, the pot rotates easily, making it very difficult to scoop with a spoon or the like. There was a problem with bad sex. Also, when used in a general home kitchen, etc.
The occupied area is required for a square circumscribing the circular outer frame 1, and there is a problem that the area of each corner portion is wasted. On the other hand, with the square inner frame type-square pot type shown in Figure 2, there is a problem that the corners of the pot and the corners of the inner frame get stuck when the pot is attached or removed, resulting in very poor operability. It was hot. In addition, since a hinge part and a hook part are required for attaching the outer lid, the above-mentioned occupied area is required to cover a rectangle circumscribing the hinge part and the hook part, resulting in a large occupied area.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a cooking utensil that improves operability and saves space.

Structure of the Invention The cooking utensil of the present invention has a main body including an outer frame having a substantially rectangular cross section, a bottomed cylindrical inner frame housed in the outer frame, and a bottomed cylindrical body removably housed in the inner frame. A hinge part provided at the upper end of one corner of an outer frame having a substantially rectangular cross section, an outer lid that covers the upper opening of the main body and is rotatably supported on the hinge part, and an outer lid that faces the hinge part. The outer frame has a hook part provided at the upper end of one corner to lock the outer lid and the main body, and a lower frame with legs that covers the bottom opening of the main body, and the cross section of the inner frame and the pot is a hinge part. - It is approximately elliptical in shape, with the short axis being the diagonal line connecting the hooks and the long axis being perpendicular to the diagonal line. With this configuration, the pot can be easily attached and removed without any hassle, and the food being cooked in the pot can be easily removed. When taking out the pot, the pot does not rotate and can be scooped out easily, making it very easy to operate.On the other hand, there is no wasted space on the top surface of the outer frame, which has a roughly rectangular cross section, and the occupied area is also small. It is possible to save space by using only a small amount.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 3 and 4, 21 is a cylindrical outer frame with a substantially square cross section, 22 is a resin annular upper frame that forms the upper end surface of the outer frame 21, and 23 is provided at the upper end of one corner of the upper frame 22. 24 covers the top opening of the upper frame 22 and is rotatably supported on the hinge 23; 25 is the upper frame 2 facing the hinge 23;
A hook part 26 is provided at the upper end of one corner of 2 to lock the outer lids 24 and 22, and the hook part 26 is drawn and formed from a thin metal plate, which is installed inside the outer frame 21 and whose upper end surface is fixed to the upper frame 22. It is a bottomed cylindrical inner frame with a substantially elliptical cross section, and the short axis of the ellipse is connected to the hinge part 23 and the hook part 2.
The major axis of the ellipse lies on the diagonal line connecting the ellipse 5 and in the direction perpendicular to the diagonal line. 27 is a cooking heater fixed to the top surface of the bottom of the inner frame 26; 28 is installed inside the inner frame 26 and is removably placed on the top surface of the heater 27; the upper section is approximately elliptical and the lower section is approximately circular. pot,
29 is a lower frame with legs that covers the lower opening of the outer frame 11.

To explain the characteristics of the above configuration, the pot 28 has an approximately elliptical upper cross section and a approximately circular lower cross section, and when set in the inner frame 26, which has a generally elliptical cross section, the pan can be inserted from any direction. I can,
When inserted, the pot 28 is set in the oval shape of the inner frame 26 while rotating. At this time, the maximum rotation angle of the pot is 90°, so there is no difficulty in operability. In addition, since there is no corner with a small radius, the pot 28 and the inner frame 26 do not get stuck, so the pot 28 can be easily set. Furthermore, when taking out the food to be cooked from inside the pot 28, the upper part of the pot 28 and the inner frame 26 have a substantially elliptical cross section, and when the pot 28 is set, it hardly rotates, so it can be easily removed with a shamoji etc. You can scoop out rice. On the other hand, both the hinge part 23 and the hook part 25 are provided inside the outer frame 21, and since the long axis of the ellipse of the pot 28 is perpendicular to the diagonal line connecting them, the inside of the outer frame 21 is Since the entire surface is effectively utilized and the occupied area is a square of the outer shape of the outer frame 21, it is very effective in saving space in a general household.

Effects of the Invention As is clear from the above embodiments, the cooking utensil of the present invention has a substantially elliptical cross section of the inner frame and the pot, which makes it easy to set the pot and take out the food to be cooked. Furthermore, the area occupied by the main body is reduced, making it possible to improve operability and save space.
