Description

  The present invention relates to a heating cooker including a main body case in which a heating body is accommodated and a cooking container placed on the heating body.

  In this type of cooking device, generally, a cooking container having a dish shape is called a hot plate, and a cooking container having a pan shape is called a grill pan.

  The main body case has a space opened on the upper surface, and is constituted by one or a plurality of resin molded members. A heating element, a thermo stud, and the like are disposed in the opening space of the main body case.

  The heating body is supported so as to be fixed or detachable with respect to the main body case. As the heating element, a cast-in heater, a sheathed heater, or the like is used. A heat shield is attached to the main body case or the heating body via a heat insulating spacer or the like.

  Furthermore, a guard surrounding the cooking container placed on the heating body is formed in the main body case. This guard reduces the exposure of the cooking container and prevents burns.

  A general guard structure has inner and outer double side walls, and a space is provided between the inner and outer side walls for heat insulation.

  There are various types of cooking containers in a form suitable for various cooking methods such as boiled foods and grilled foods.

  Conventionally, there is a cooking container in which a handle member is attached to a flange formed on the outer periphery of a side peripheral wall of the cooking container (for example, Patent Document 1).

  In addition, there is a case in which a handle portion is integrally provided by projecting a part of a flange formed on the outer periphery of the side peripheral wall of the cooking container to the outside (for example, Patent Document 2).

Japanese Patent Laid-Open No. 11-46976 (FIG. 1) JP-A-8-256911 (FIGS. 1 and 2)

  However, in any of the above-described conventional examples, the handle portion protrudes outward from the side peripheral wall of the cooking container, so that there is a problem that the outer dimensions of the cooking container become large.

In addition, when cooking pottery with a cooking container, the cooking container becomes particularly hot. However, in the case where the handle portion is provided integrally with the flange of the cooking container, when the flange is surrounded by the guard, the main body case becomes too large, so that the flange protrudes above the guard. If the outer periphery of the cooking container is made smaller, the bottom plate portion serving as a cooking surface becomes smaller.
Therefore, the contact between the flange and the hand cannot be prevented by the guard, and there is a problem that a detachable guard ring is required separately.

  Accordingly, a first object of the present invention is to provide a main body case in which a heating body is accommodated and a cooking container placed on the heating body, and form a guard that surrounds the cooking container in the main body case. In the cooking device in which a flange is formed on the outer periphery of the side peripheral wall, the handle portion is provided integrally with the cooking vessel, and the external dimensions of the cooking vessel are reduced without reducing the bottom plate portion of the cooking vessel. Furthermore, it is to prevent a flange and a hand from contacting with a guard, without enlarging a main body case.

  In order to achieve the first object, the present invention includes a main body case in which a heating body is accommodated, and a cooking container placed on the heating body, and the main body case includes a guard that surrounds the outer periphery of the cooking container. The heating cooker which has has the structure which formed the handle part by making the root of the flange partly indented inside the side wall of the cooking vessel.

  Specifically, of the side peripheral wall of the cooking container, a portion that extends inward is formed on the lower surface of the flange by a configuration in which the handle portion is formed by partially indenting the base of the flange. This part was made to be a handle part. Therefore, the handle portion is provided integrally with the cooking container.

  Moreover, since the handle portion is formed using the flange, it is only necessary to make the flange base portion of the side peripheral wall shallowly recessed, and the bottom plate portion does not become small.

  Moreover, since the handle part does not protrude outward from the flange, the outer dimension of the cooking container is smaller than that of the conventional example.

  In order to achieve the above second object, in the present invention, in the above configuration, the flange is further positioned on the inner side of the inner periphery of the guard as viewed from above, and a portion higher than the flange is formed on the guard. This configuration is adopted.

  Specifically, the flange is positioned so as to be located inside the inner periphery of the guard as viewed from above, so that the flange does not protrude above the guard. Since the outer dimension of the cooking container is smaller than that of the conventional example, the guard does not increase outward.

Since the flange does not protrude above the guard, the guard can be configured to have a portion higher than the flange. Such a guard high portion prevents contact between the flange and the hand.
In addition, the said guard high part may be provided over the guard whole periphery, and may be provided partially in a required range.

  Moreover, in the said structure, the side peripheral wall of the said cooking container is formed so that it may expand upward, and it shall employ | adopt the structure dented so that it may not overlap with the bottom plate part inner surface of the said cooking container when it sees from upper direction. Is preferred.

If the side peripheral wall of the cooking container is formed so as to expand upward, a space accompanying the expansion of the side peripheral wall is formed outside the upper side of the inner surface of the bottom plate portion inside the cooking container.
If the space is used, a configuration in which the side peripheral wall of the cooking container is recessed so as not to overlap the inner surface of the bottom plate portion of the cooking container when viewed from above is possible.
By adopting such a configuration, the bulging portion of the side peripheral wall due to the recess is removed from above the inner surface of the bottom plate portion, and does not interfere with placing the food on the inner surface of the bottom plate portion.
Therefore, according to this structure, the inner surface of the bottom plate portion can be used entirely as a pottery cooking surface.

  Moreover, in the said structure, if the structure which formed the slip stopper which consists of a protrusion in the flange lower surface part which forms the said handle part is employ | adopted, it can make it difficult to remove | deviate a finger from the said handle part.

As described above, the present invention cooks the handle portion by adopting a characteristic configuration in which the handle portion is formed by partially indenting the base of the flange in the side peripheral wall of the cooking container. Provided integrally with the container, the outer dimensions of the cooking container can be reduced without reducing the bottom plate of the cooking container.
According to the present invention, further, the flange is positioned on the inner side of the inner periphery of the guard as viewed from above, and the guard is formed without forming a main body case by adopting a configuration in which a portion higher than the flange is formed. This prevents contact between the flange and the hand.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, the cooking device according to this embodiment includes a main body case 2 in which the heating body 1 is accommodated and a cooking container 3 placed on the heating body 1.

  The main body case 2 is divided into two parts in the vertical direction, and an opening space is formed on the upper surface. The divided pieces of the main body case 2 are integrally molded with resin.

  The heating body 1 is supported above the bottom in the opening space. As the heating element 1, a heating plate in which an electric heater is cast is used.

  The cooking container 3 has a round pan shape in which a side peripheral wall 32 connected to the bottom plate portion 31 is formed to expand upward.

  The inner surface of the bottom plate portion 31 is a grilled cooking surface on which an uneven structure is formed. The eluted oil from the cooked food heated at the bottom plate portion 31 flows from the concave portion to the continuous portion with the side peripheral wall 32 and accumulates in this portion.

  The outer bottom surface of the bottom plate portion 31 and the center of the plate surface of the heating element 1 are on the same axis, and are in line contact with each other on a circumference centered on the axis. Thereby, the sitting of the cooking container 3 is improved, reliable heat conduction is obtained, and the cooking container 3 is not rotated unless the cooking container 3 is turned by hand.

  A flange 33 is formed on the outer peripheral upper end of the side peripheral wall 32 of the cooking container 3 over the entire periphery.

  As shown in FIGS. 3 and 4, the cooking container 3 is extracted and shown at the base of the flange 33 in the side wall 32, and flat portions 34 and 34 are formed by being partially recessed inward. .

  Along with the concave formation of the flat surface portion 34, the flange width is expanded inward on the lower surface of the flange 33, and the expanded portion is a handle portion 35. The handle portion 35 is formed in an opposing arrangement in the circumferential direction.

A downward projecting portion 35 a is formed on the lower surface portion of the flange forming the handle portion 35. Even when the fingertip is about to slide outward in a state where the fingertip is hung on the handle portion 35, it is restricted by the protrusion 35a. That is, the protrusion 35a is non-slip.
The protrusion 35 extends over the entire circumference of the flange 33 for reinforcement, but may be formed at least on the flange lower surface portion that forms the handle portion 35. In addition, the form of the protrusion part 35a can be changed suitably, and can also be comprised from several protrusion.

Here, as shown in FIGS. 1 and 2, the bulging portions 36 and 36 are formed on the inner periphery of the side peripheral wall 32 in accordance with the concave formation of the flat portions 34 and 34. The bulging portions 36 and 36 do not overlap the inner surface of the bottom plate portion 31 in the vertical direction when viewed from above. That is, the bulging portions 36 and 36 are removed from above the inner surface of the bottom plate portion 31, and do not interfere with placing the food on the inner surface of the bottom plate portion 31.
Therefore, this cooking container 3 can use the inner surface of the bottom plate part 31 entirely as a pottery cooking surface.

  The main body case 2 is provided with a guard 21 that surrounds the cooking container 3 placed on the heating body 1 from the outside. The guard 21 includes inner and outer double side walls 22 and 23 and has a structure in which a space is provided between the inner and outer side walls 22 and 23.

  The upper part of the inner periphery of the guard 21 has a substantially cylindrical shape that is separated from the side peripheral wall 32 over the entire circumference in order to allow the cooking container 3 to be manually turned on the heating body 1.

  The upper surface of the flange 33 has a constant width when viewed from above, and is positioned on the inner side of the inner peripheral upper portion of the guard 21 while being placed on the heating body 1. Since the cooking container 3 can rotate on the heating body 1, there is no directionality in the mounting of the cooking container 3. FIG.

  A pair of recesses 24, 24 are formed on the upper surface of the guard 21 in the circumferential direction. The recesses 24, 24 form a gap where a finger can be put on the handle portion 35 in a state where the cooking container 3 is placed on the heating body 1.

  In addition, when the cooking container 3 is inclined and placed on the heating body 1, the concave portions 24 and 24 and the handle portions 35 and 35 can be placed on the heating body 1 in a state of being displaced. Even in this misaligned state, there is no direction in placing the cooking container 3, so that cooking with no problems is possible. When the cooking container 3 is removed from the heating body 1, the concave portions 24, 24 and the handle portions 35, 35 can be aligned by hand-turning on the heating body 1.

Here, in the heating cooker according to this embodiment, the portion located between the recesses 24 and 24 in the circumferential direction in the upper portion of the inner periphery of the guard 21 (hereinafter, such portion is denoted by reference numeral 25, and merely the upper middle portion). The space between the side wall 32 of the cooking container 3 and the cooking container 3 is narrowed.
According to this configuration, since a finger is prevented from entering the separation gap, safety can be improved.
In addition, the inner circumference of the guard 21 is reduced, and the separation gap is less conspicuous in appearance, so that the design can be improved.

  In addition, the said recessed parts 24 and 24 form an oblique clearance between the handle parts 35 and 35. FIG. This is to reduce as much as possible the portions of the recesses 24, 24 where the side peripheral wall 32 of the cooking container 3 is exposed.

  The upper intermediate portion 25 of the guard 21 is easily heated by the radiant heat from the cooking container 3 as a result of the space between the side peripheral wall 32 of the cooking container 3 being narrowed. For this reason, most of the upper intermediate portion 25 of the guard 21 is covered with the heat reflecting plate 26. Thereby, the high temperature of the guard 21 is prevented.

  The upper intermediate portion 25 of the guard 21 is higher than the flange 33. For this reason, most of the flange 33 (excluding the portion located in the recesses 24 and 24 in the circumferential direction) is difficult to touch by the upper middle portion 25 of the high guard 21 on the outside.

  As described above, in the cooking device according to this embodiment, the handle portion 35 is provided integrally with the cooking container 3 by the recess of the side peripheral wall 32.

  Further, the bottom plate portion 31 of the cooking container 3 is not reduced in size because the side peripheral wall 32 is only partially recessed inside.

  Further, the outer dimensions of the cooking container 3 are smaller than the conventional example because the handle portions 35, 35 do not protrude outward from the flange 33.

  Further, the flange 33 does not protrude above the guard 21. Since the handle portions 35 and 35 do not protrude outward from the flange 33, the guard 21 of the main body case 2 does not become large.

  Further, in the cooking device according to this embodiment, the flange 33 does not protrude above the guard 21, and therefore, the upper middle portion 25 higher than the flange 33 can be formed on the guard 21 without enlarging the main body case 2. The upper middle portion 25 can prevent the flange 33 from contacting the hand.
