Even in a state where the upper heating unit 21 is attached to the cylinder unit 12, the food can be stored and taken out from the lower food storage unit 15 of the lower heating unit 11. Therefore, during cooking, the food is stored and taken out from the upper food storage unit 25 of the upper heating unit 21 and the food is stored and taken out from the lower food storage unit 15 of the lower heating unit 11 at the same time. Therefore, by using the upper food storage unit 25 and the lower food storage unit 15, a plurality of types of heat cooking can be performed at the same time.

  Next, the structure which attaches the said upper side heating part 21 to the cylinder part 12 of the lower side heating part 11 is demonstrated in detail.

  FIG. 5 is a side view of the upper heating unit of the cooking device in the embodiment of the present invention, FIG. 6 is a perspective view showing the lower surface side of the upper heating unit of the cooking device in the embodiment of the present invention, and FIG. FIG. 8 is an exploded view of the cooking device according to the embodiment of the invention, and FIG. 8 is a side sectional view of the cooking device according to the embodiment of the present invention.

  As shown in the drawing, a plurality of engaging protrusions 22 extend downward from the back surface portion 21c of the bottom portion 21a of the upper heating portion 21. The engaging protrusion 22 is preferably a member formed integrally with the bottom 21a, but may be a member formed separately and attached to the bottom 21a by means such as welding. In the example shown in the figure, the number of the engaging protrusions 22 is six, but any number may be used as long as it is two or more.

  The engaging protrusion 22 is preferably formed on the surface of the back surface portion 21c so as to form a circle having a diameter corresponding to the upper end edge 12a of the cylindrical portion 12 and adjacent ones are separated from each other. Are arranged at equal intervals. The circle is preferably concentric with the outer periphery of the bottom 21a.

  In addition, an engagement recess 23 that engages with the upper end portion of the cylindrical portion 12 is formed at the tip of the engagement protrusion 22, that is, outside the lower end (side wall portion 21 b side). The engagement recess 23 includes a lateral engagement surface 23a and a longitudinal engagement surface 23b, and has a shape such that the lateral engagement surface 23a and the longitudinal engagement surface 23b intersect in a side section. Prepare. As shown in FIG. 8, in a state where the upper heating portion 21 is attached to the cylindrical portion 12, the lateral engagement surface 23 a is engaged with the upper end edge 12 a of the cylindrical portion 12, The vertical engagement surface 23 b faces and engages with the upper end inner surface 12 b of the cylindrical portion 12.

  The lateral engagement surface 23a is formed so that, for example, the lateral engagement surfaces 23a of all the engagement protrusions 22 are included in the same plane parallel to the back surface portion 21c of the bottom portion 21a. Further, the vertical engagement surface 23b is formed, for example, so that the vertical engagement surfaces 23b of all the engagement protrusions 22 are included in the same cylindrical side surface or the same truncated cone side surface.

  The upper end inner surface 12b is a portion adjacent to the upper end edge 12a on the inner side surface of the cylindrical portion 12, and may have the same shape as the side surface of the truncated cone whose upper base diameter is smaller than the lower base diameter. The shape may be the same as the side surface of the cylinder, or may be the same shape as the side surface of the truncated cone having a diameter of the upper base larger than the diameter of the lower base. The diameter of the upper end inner surface 12b is set to be equal to or larger than the diameter of the side surface of the cylinder or the truncated cone including the vertical engagement surfaces 23b of all the engagement protrusions 22.

  And when attaching the upper side heating part 21 to the lower side heating part 11, while the upper side heating part 21 is located above the lower side heating part 11, as shown in FIG. The engaging protrusion 22 faces downward, faces the upper end edge 12a of the cylinder part 12, and is arranged so that the back surface part 21c of the bottom part 21a is substantially parallel to the upper end edge 12a of the cylinder part 12. Subsequently, the upper heating unit 21 is moved relative to the lower heating unit 11 so that the upper heating unit 21 and the lower heating unit 11 approach each other. Then, the distal end of the engagement protrusion 22 is caused to enter the cavity 13 from the upper end side of the cylinder portion 12, and the engagement protrusion 22 is engaged with the upper end portion of the cylinder portion 12.

  In this way, when the attachment to the lower heating unit 11 of the upper heating unit 21 is completed, the state shown in FIGS. That is, the engaging protrusion 22 engages with the upper end portion of the cylindrical portion 12 so that the upper heating portion 21 is stably attached to the cylindrical portion 12, and the back surface portion 21 c of the upper heating portion 21 and the upper edge of the cylindrical portion 12 The portion where the engaging protrusion 22 does not exist between the portion 12 a and the window portion 14 that communicates the cavity portion 13 formed inside the tube portion 12 with the outside of the tube portion 12.

  In addition, as shown in FIG. 8, the engagement recess 23 of the engagement protrusion 22 engages with the upper end portion of the cylindrical portion 12. More specifically, the lateral engagement surface 23a of the engagement recess 23 faces and engages with the upper end edge 12a of the cylindrical portion 12, and the vertical engagement surface 23b of the engagement recess 23 is The upper end inner surface 12b is faced and engaged. Therefore, since the engaging protrusion 22 is reliably engaged with the upper end portion of the cylindrical portion 12, the upper heating portion 21 is securely and stably attached to the lower heating portion 11, and during heating cooking. Even if an external force is applied to the upper heating unit 21 via a cooking utensil or the like, the upper heating unit 21 does not come off the lower heating unit 11.

  And when performing cooking using the cooking utensil 10 which attached the upper side heating part 21 to the lower side heating part 11, desired foodstuffs in the upper side foodstuff accommodation part 25 and / or the lower side foodstuff accommodation part 15 The lower heating unit 11 to which the upper heating unit 21 is attached is placed on a heating appliance such as a gas stove or electric stove. Specifically, the back surface part 11c of the bottom part 11a of the lower heating part 11 is placed on a virtues such as a gas stove or a heating part of an electric stove.

  Subsequently, when heating by the heating tool is started, the bottom 11a of the lower heating unit 11 is heated by the heating tool. Thereby, the foodstuff accommodated in the lower foodstuff accommodation part 15 is heat-cooked. Moreover, the hot air by heating enters and rises into the cavity portion 13 through the opening at the lower end of the cavity portion 13 located at the center of the back surface portion 11c of the bottom portion 11a.

  Here, since the upper end of the cavity portion 13 communicates with the outside of the cylindrical portion 12 through the window portion 14, the hot air that enters and rises into the cavity portion 13 is transmitted from the window portion 14 to the cavity portion 13. You can get out of. That is, the upper end of the cavity portion 13 communicates with the outside through the window portion 14, so that a so-called chimney effect is exhibited, and the cavity portion 13 functions as a kind of chimney, and sucks hot air from the lower end and discharges it from the upper end. To function. Therefore, the hot air generated by the heating of the heater is effectively sucked by the cavity 13 and discharged from the window 14. At this time, since the hot air flows radially outward along the back surface portion 21c of the bottom portion 21a of the upper heating portion 21, the bottom portion 21a is effectively heated. As a result, the food stored in the upper food storage unit 25 is cooked at a high temperature.

  Further, the hot air sucked by the cavity portion 13 rises along the side surface of the cavity portion 13, that is, the inner side surface of the cylinder portion 12, so that the cylinder portion 12 is heated. Then, the heat in the cylindrical portion 12 is transmitted from the upper end of the cylindrical portion 12 to the bottom portion 21 a of the upper heating portion 21 through the engaging protrusion 22. Here, since the horizontal engagement surface 23a and the vertical engagement surface 23b of the engagement protrusion 22 are engaged with the upper end edge 12a and the upper end inner surface 12b of the cylindrical portion 12, the engagement protrusion 22 The area of the heat transfer surface between the cylinder portion 12 and the cylinder portion 12 is wide. Therefore, the heat transfer rate from the cylindrical portion 12 to the engaging protrusion 22 is extremely high, and a large amount of heat is transmitted to the bottom 21a of the upper heating portion 21 via the engaging protrusion 22, The bottom 21a is heated more effectively. In particular, in the present embodiment, the area in which the vertical engagement surface 23b of the engagement protrusion 22 and the upper end inner surface 12b of the cylindrical portion 12 are engaged, that is, the vertical engagement surface 23b is connected to the upper end inner surface 12b. Since the overlapping area is large, the heat transfer rate from the cylindrical portion 12 to the engaging protrusion 22 is extremely high. Therefore, the bottom 21a can be heated to an extremely high temperature, and the food stored in the upper food storage 25 is cooked at a high temperature.

  For example, while using the lower side heating part 11 as a pan, the upper side heating part 21 can be used as an iron plate for teppanyaki. That is, while cooking food such as vegetables and soup in the lower food container 15 and cooking food in a pan, the food ingredients such as meat and fish are stored in the upper food container 25 and cooking on a teppanyaki. It can be carried out. In this case, even if a general household heating appliance such as a household gas stove or a household electric stove is used, the lower heating unit 11 is heated to appropriately boil the ingredients in the lower food storage unit 15. The upper heating part 21 can be sufficiently heated by the chimney effect exhibited by the cavity part 13 and the extremely high heat transfer rate from the cylindrical part 12 to the engaging protrusion part 22. The foodstuff in the foodstuff storage part 25 can be baked at high temperature. Further, even if the upper heating part 21 is pushed or struck with chopsticks or the like during cooking, the engagement protrusion 22 is securely engaged with the upper end portion of the cylindrical part 12, so the posture of the upper heating part 21 Is not changed, and the upper heating unit 21 is not detached from the lower heating unit 11.

  In addition, if the shape of the upper end inner surface 12b of the cylinder part 12 and the shape of the vertical engagement surface 23b of the engagement protrusion 22 are the same shape, that is, the upper end inner surface 12b is the same shape as the side surface of the cylinder. In addition, if the vertical engagement surface 23b has the same shape as the side surface of the cylinder of the same size, the vertical engagement surface 23b comes close to or abuts with the upper end inner surface 12b in a larger area. The heat transfer rate to the part 22 can be further increased.

  Further, the upper end inner surface 12b has the same shape as the side surface of the truncated cone having the upper base diameter larger than the lower base diameter, and the longitudinal engagement surface 23b has the same size cone as the upper base diameter larger than the lower base diameter. If the shape is the same as that of the side surface of the base, the vertical engagement surface 23b comes close to or abuts with the upper end inner surface 12b in a wider area, so that the heat transfer rate from the cylindrical portion 12 to the engagement protrusion 22 is further increased. Can be high. Furthermore, since the engaging protrusion 22 is reliably engaged with the upper end portion of the cylindrical portion 12, the upper heating portion 21 can be more securely and more stably attached to the lower heating portion 11. In addition, it can also be used for heating cooking in the state which removed the upper side heating part 21, ie, only the lower side heating part 11. FIG.

  As described above, in the present embodiment, the cooking device 10 includes a flat bottom portion 11a having an annular shape, a side wall portion 11b that rises from the outer peripheral edge of the bottom portion 11a and surrounds the periphery of the bottom portion 11a, and the bottom portion 11a. A lower heating portion 11 including a hollow cylindrical portion 12 rising from an inner peripheral edge of the upper portion, a flat bottom portion 21a, and a plurality of engaging protrusions 22 extending from a back surface portion 21c of the bottom portion 21a. When the heating projection 11 has an upper heating portion 21 that can be attached to and detached from the heating portion 11 and the engaging projection 22 is engaged with the upper end portion of the cylindrical portion 12, the upper heating portion 21 is connected to the back surface portion 21 c of the bottom portion 21 a and the cylindrical portion 12. It is attached to the lower heating unit 11 in a state in which the upper edge 12a is spaced apart and a window portion 14 is formed which communicates with the hollow portion 13 inside the cylindrical portion 12.

  Therefore, the hot air that has entered the cavity portion 13 from below is smoothly discharged from the upper window portion 14 due to the chimney effect, so that the bottom portion 21a of the upper heating portion 21 is effectively heated by the hot air rising in the cavity portion 13. At the same time, the heat from the cylinder portion 12 is transmitted through the engagement protrusion 22, so that the bottom portion 21 a of the upper heating portion 21 is further effectively heated. Thereby, for example, while using the lower heating part 11 as a pan, the upper heating part 21 can be used as an iron plate for teppanyaki. That is, while having a simple configuration, a plurality of types of heating cooking can be performed at the same time, and the usability is good. Further, the cost can be reduced. Furthermore, since the engaging protrusion 22 engages with the upper end portion of the cylindrical portion 12, the upper heating portion 21 is securely and stably attached to the lower heating portion 11, and the posture of the upper heating portion 21 changes. Or the upper heating unit 21 is not detached from the lower heating unit 11. Therefore, it is safe and the reliability can be increased.

  Each of the engagement protrusions 22 includes an engagement recess 23 that engages with the upper end portion of the cylindrical portion 12, and the engagement recess 23 includes a lateral engagement surface 23a and a longitudinal engagement surface 23b. When the upper heating unit 21 is attached to the lower heating unit 11, the lateral engagement surface 23 a faces and engages with the upper end edge 12 a of the cylindrical portion 12, and the vertical engagement surface 23 b is connected to the cylindrical portion 12. The upper end inner surface 12b is faced and engaged. Therefore, the engagement between the engagement protrusion 22 and the upper end portion of the cylindrical portion 12 is ensured. In addition, since the overlapping area is large, the area of the heat transfer surface between the engagement protrusion 22 and the cylinder 12 is increased, and the heat transfer rate from the cylinder 12 to the engagement protrusion 22 is extremely high. . Therefore, a large amount of heat is transmitted to the bottom portion 21a of the upper heating portion 21 via the engaging projection portion 22, so that the bottom portion 21a can be heated more effectively.

  Further, the bottom portion 21a of the upper heating unit 21 has a larger area than the opening at the upper end of the hollow portion 13 of the cylindrical portion 12, and when the upper heating portion 21 is attached to the lower heating portion 11, the opening at the upper end of the hollow portion 13 is The upper part is covered with the bottom part 21a of the upper heating part 21. Therefore, the hot air that rises in the hollow portion 13 and is discharged from the window portion 14 flows along the back surface portion 21c of the bottom portion 21a of the upper heating portion 21, so that the bottom portion 21a can be heated more effectively.

  In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.

  The present invention can be applied to a cooking device used for cooking food.
