The present invention relates to an electric cooker having a stacking structure that can be positioned by the above.

When cooking using the cooking pot, the above-mentioned electric cooking device selects each cooking pan according to the contents of cooking, places it on the electric cooking device body, and cooks with heat from the heating unit It can be performed. In addition, when storing cooking pots in an electric cooker after cooking, each cooking pot is placed on the electric cooker body in order and positioned in the electric cooker body while saving space. Can be stored.
As such a conventional electric cooker, for example, an electric cooker 70 described in Patent Document 1 can be cited.
In Patent Literature 1, as shown in FIG. 8, an electric cooker main body 72 having a heating unit 71, a cooking pan 73 that is placed on the electric cooker main body 72 and can be heated by the heating unit 71, and a plurality of An electric cooker 70 having a flange portion 74 formed on the outer periphery of the cooking pan 73 and a pair of grips 75 disposed in the flange portion 74 so as to face each other in the radial direction is disclosed.
In this electric cooker 70, as a plurality of cooking pots 73, a deep pan 73a, a shallow deep yakiniku plate 73b and a flat plate 73c are used, and the deep pan 73a is a yakiniku plate 73b and a flat plate 73c. It is formed in a size that is larger in the radial direction than the cooked food spilled from the deep pan 73a during cooking. Therefore, the handle 75 attached to the flange portion 74 has a different shape corresponding to the outer periphery of each cooking pan 73 and the like. The lower part is provided with a downward projecting locking part 77 (corresponding to the engaging convex part 22b in the specification of Patent Document 1) in a different shape.
And when storing the electric cooker 70 etc., it placed in the electric cooker main body 72 in order of the deep pan 73a, the grilled meat plate 73b, and the plane plate 73c, and was provided in the lower part of the handle 75 of the grilled meat plate 73b. The radially inner side 77a of the downward projecting locking portion 77 is locked to the radially outer side 76a of the upper locking portion 76 provided on the upper portion of the handle 75 of the deep pan 73a, and provided on the lower portion of the handle 75 of the flat plate 73c. The stacking structure that locks the radially inner side 77a of the downward projecting locking part 77 to the radially outer side 76a of the upper locking part 76 provided at the upper part of the handle 75 of the grilled meat plate 73b, while saving space.

It is said that.

On the other hand, in the electric cooker 70 described in Patent Document 1, the handle 75 of each cooking pan 73 has a different shape. An electric cooker 80 having a stacking structure for positioning on the main body 72 is known (see FIG. 9). Thereby, by using the common handle 81, the manufacture of the handle 81 is quick and easy, and an increase in manufacturing cost can be prevented.
JP 11-318701 A

In the electric cooker 70 described in Patent Literature 1, as shown in FIG. 8, in order to store the electric cooker 70, the electric cooker main body 72 is placed in the order of a deep pan 73a, a grilled meat plate 73b, or a flat plate 73c. When placing, the radially inner side 77a of the downward projecting locking portion 77 provided at the lower portion of the handle 75 of the grilled meat plate 73b or the flat plate 73c is connected to the upper portion provided at the upper portion of the handle 75 of the deep pan 73a. The deep pan 73a and the grilled meat plate 73b or the flat plate 73c are positioned by the stacking structure that is engaged with the radially outer side 76a of the stopper 76.
However, when the cooking pan 73 such as the deep pan 73a or the flat plate 73c is manufactured with relatively low molding accuracy by pressing or the like, the deep pan 73a or the flat plate placed on the electric cooker main body 72 is used. There is a possibility that 73c and the like come into contact with each other at a portion other than the handle 75. That is, when the cooking pots 73 are sequentially placed, the cooking pots 73 are positioned by locking the handles 75, but the cooking pots 73 are relatively close to each other and have predetermined dimensions. If not correctly formed, there is a problem that these cooking pans 73 may come into contact with each other and be damaged.
In particular, the radial direction of the radially inner side 77a of the downward projecting locking part 77 provided at the lower part of the handle 75 of the flat plate 73c or the grilled meat plate 73b and the upper locking part 76 provided at the upper part of the handle 75 of the deep pan 73a. When the outer pot 76a is locked and the deep pot 73a and the flat plate 73c or the grilled meat plate 73b are positioned, the deep pot 73a, the flat plate 73c, etc. are not accurately formed with predetermined dimensions. The gap between the cooking pots 73 is obtained by adding the dimensional variation of each part up to the locking portion on the one handle 75 side and the other handle 75 side, and one of the flat plate 73c or the grilled meat plate 73b is added. When some external force is applied from the handle 75 side to the other handle 75 side, the cooking pans 73 are likely to contact each other. Further, when some external force is applied from one handle 75 side of the flat plate 73c or the grilled meat plate 73b to the other handle 75 side, the downward projecting mechanism provided at the lower part of the one handle 75 with the other handle 75 side as a fulcrum. The stop portion 77 gets over the upper locking portion 76 provided on the upper portion of the handle 75 of the deep pan 73a, and the flat plate 73c and the like is tilted and moves in the radial direction (the other handle 75 side). There exists a problem that there exists a possibility that pan bottoms, such as the plane plate 73c near the side, may contact the pan wall of the deep pan 73a.
Furthermore, in the electric cooking device 70 described in Patent Document 1, each cooking pan 73 manufactured by press working or the like is shaped as it is without being particularly processed (for example, a cutout portion is provided in the outer flange). Therefore, it is possible to obtain a product by attaching a handle 75 to each cooking pan 73 via an attachment 78 or the like, which is quick and easy to manufacture and prevents an increase in manufacturing cost. However, in this electric cooker 70, when the outer diameters of the cooking pots 73 are different, the handle 75 having the same shape cannot be used unless the fixture 78 is processed, and the manufacturing cost increases. There is a problem.

  On the other hand, in the electric cooking device 80 using the handle 81 having the same shape, if only one type of handle 81 is prepared, the deep pan 73a and the flat plate 73c can be positioned, thereby preventing an increase in manufacturing cost. Although the deep pot 73a and the flat plate 73c are formed so as to have different outer diameters, for example, as shown in FIG. 10, a notch 82 is provided in the outer peripheral flange 74 of the deep pot 73a. Thus, the handle 81 having the same shape cannot be used unless the handle 81 is arranged in the notch 82. Therefore, even when the deep pan 73a, the flat plate 73c, and the like are manufactured by press working to make a simple manufacturing method, it is necessary to further process and arrange the handle 81, and quick and easy manufacturing. However, there is a problem that the manufacturing cost increases.

  The present invention has been made paying attention to such a point, and the purpose thereof is that each cooking pan placed on the electric cooker body, for example, a deep pan, a flat plate, a grilled meat plate, etc. are portions other than the handle. It is in the point which provides the electric cooker which has a stacking structure which can position each cooking pan while being able to prevent that it contacts, and is damaged, etc., and can position each cooking pan reliably.

In order to achieve this object, a first characteristic configuration of an electric cooking device according to the present invention includes an electric cooking device body having a heating unit, and cooking that is placed on the electric cooking device body and can be heated by the heating unit. and pan, the flange portion is formed on the outer periphery of the cooking pot, and a pair of handles which are placed opposite to the flange portion in the radial direction, the first cooking by a plurality of the cooking pot pan and second A cooking pot and a third cooking pot, and at least one of the first cooking pot and the second cooking pot is formed by pressing, and the grips of the plurality of cooking pots are common. The handle is provided with an upper locking portion and a downward projecting locking portion, and the radially outer end of the handle of the first cooking pan is connected to the second cooking pan and the second cooking pan. 3 protrudes outward in the radial direction from the radially outer end of the handle of the cooking pan 3 While being formed, the second cooking pot and a radially outer end of the handle of the third cooking pot is formed in the same outer diameter, placing the second cooking pot to the first cooking pot and, wherein the radially outside of the lower side projecting engaging portion provided on the handle of the second cooking pot, said first radial inward engaging the upper side engaging portion provided on the handle of the cooking pot Then, the first cooking pot and the second cooking pot are positioned on the electric cooker main body, and the third cooking pot is placed on the second cooking pot, The radially inner side of the downward projecting locking portion provided on the handle of the cooking pan 3 is locked to the radially outer side of the upper locking portion provided on the handle of the second cooking pan, and the second And a third cooking pot are positioned on the electric cooker body .

According to the said 1st characteristic structure, when the 1st cooking pot and the 2nd cooking pot are sequentially mounted in the electric cooker main body, the downward protrusion latching provided in the handle of the said 2nd cooking pot The first cooking pot and the second cooking pot are positioned by engaging the radially outer side of the portion with the radially inner side of the upper locking portion provided on the handle of the first cooking pot.
Therefore, the downward projecting locking portion of the handle provided in the second cooking pan is radially inward of the upper locking portion provided in the handle of the first cooking pan (on the center side of the second cooking pan). ), The lateral movement of the cooking pot can be controlled very close to the pot wall where the two cooking pots may come into contact. Specifically, even if some external force is applied from one grip side of the second cooking pan to the other grip side and a slight relative movement occurs, the second cooking pan is placed on the first cooking pan. Since the gap between the two is basically set by the handle on the other handle side, the contact between the cooking pans can be minimized. Further, even if some large external force is applied from one handle side of the second cooking pan to the other handle side, the downward projecting locking portion on the one handle side of the second cooking pan is the first cooking pan. It is possible to prevent the second cooking pot from tilting and the bottom of the second cooking pot from coming into contact with the pot wall of the first cooking pot without getting over the upper locking portion on the one grip side. Similarly, even if some large external force is applied from one handle side of the second cooking pan to the other handle side, the radially outward side of the downward projecting locking portion on the other handle side of the second cooking pan. Is locked on the radially inner side of the upper locking portion on the other handle side of the first cooking pan, and the second protruding locking portion and the upper locking portion are locked at the second locking portion. Gravity due to the cooking pan itself acts downwardly on the second cooking pan, so that it is firmly locked, and the second cooking pan cannot move easily even if it tries to move radially outward. It is possible to satisfactorily prevent the bottom of the second cooking pan from coming into contact with the pan wall of the first cooking pan.

Moreover, since the radial direction outer end of the handle of the 1st cooking pot protrudes in the radial direction rather than the radial direction outer end of the handle of the 2nd cooking pot, each cooking pot was positioned in the electric cooker main body. In this case, all the cooking pots can be easily removed by lifting the first cooking pot. Moreover, if the positional relationship between the handle of the first cooking pot and the handle of the second cooking pot is kept as described above, the outer diameter of the first cooking pot itself is made larger than the outer diameter of the second cooking pot itself. Since the outer ends of the handles of the first cooking pot and the second cooking pot do not come to the same outer diameter position even when the size is increased, the outer diameter portion and the handle of the second cooking pot located on the upper side It is possible to prevent the attachment member provided between the second cooking pan and the handle from being visually recognized and impairing the appearance.

Furthermore, on the electric cooker main body, the first cooking pot, the second cooking pot, and the third cooking pot are placed in this order, and the downward projecting locking portion provided on the handle of the third cooking pot. The second cooking pot and the third cooking pot are positioned with the radially inner side being locked to the radially outer side of the upper locking portion provided in the handle of the second cooking pot. At this time, the radially outer ends of the handles respectively disposed in the second cooking pot and the third cooking pot have the same outer diameter in the radial direction.
Therefore, the radially outer end of the handle disposed in the second and third cooking pots is disposed more inside in the radial direction than the radially outer end of the handle disposed in the first cooking pot. Therefore, even if the stacking structure has a structure different from that of the handle of the first cooking pot and the handle of the second cooking pot, the second cooking pot and the third cooking pot are sufficiently provided. Positioning can be performed in a stable state.

Moreover, since the handle of each cooking pan is formed in the same shape, it is only necessary to manufacture one kind of common handle, and the manufacturing cost of the handle can be reduced. Moreover, since this common handle is provided with the upper latching | locking part and downward protrusion latching part which have a common shape, each cooking pot is latched by the said upper latching | locking part and the downward projection latching part. And can be positioned. At this time, since it is not necessary to perform a process such as providing a notch in each cooking pot even if a common handle is used, the manufacturing of each cooking pot is simple and the manufacturing cost can be reduced.

In addition, since at least one of the first cooking pot and the second cooking pot is formed by pressing, it can be manufactured quickly and easily as a simple manufacturing method, and the manufacturing cost can be reduced. . In addition, when a cooking pan is formed by press processing, the molding accuracy becomes relatively low. However, since the first cooking pan and the second cooking pan are reliably positioned as described above, the first cooking pan and the first cooking pan The two cooking pots are prevented from coming into contact with each other easily.

An embodiment of an electric cooking device 100 according to the present application will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the electric cooker 100 includes an electric cooker body 1 having a heating unit 4, and a cooking pot 2 that is placed on the electric cooker body 1 and can be heated by the heating unit 4. The lid member 3 capable of closing the upper open surface of each of the plurality of cooking pans 2 is configured.
And when cooking using the electric cooker 100, each cooking pan 2 according to the content of cooking is each mounted in the said electric cooker main body 1, and the heat | fever from the heating part 4 of a cooking thing is carried out. Each cooking pan 2 can perform cooking, for example, as shown in FIG. 1, a deep pan 5 having a deep depth as a first cooking pan, and a flat plate 6 having a shallow depth as a second cooking pan, The third cooking pot is constituted by the grilled meat plate 7 having a shallow depth.
Further, when the electric cooker 100 is not used, for example, after cooking and storing, as shown in FIG. 2, each cooking pan 2 (deep pan 5, flat plate 6, yakiniku plate 7) and lid member 3 are sequentially placed. Then, the electric cooker body 1 can be placed on the electric cooker body 1 while being placed in the electric cooker body 1 while saving space.

Next, each member which comprises the electric cooker 100 is demonstrated.

A heat shield plate 11 having a flat U-shaped flat cross section disposed so as to form a gap and a heating unit 4 disposed so as to form a predetermined gap with the heat shield plate 11 via a support member 12. It is prepared for.
A cylindrical case 8 constituting the electric cooker body 1 has a double structure of an outer wall 13 and an inner wall 14, and an opening in which a plurality of cooking pans 2 can be placed on the upper surface of the case 8. Is formed. The outer wall 13 constitutes a bottom portion 13a of the electric cooker body 1 and a cylindrical outer periphery 13b rising from the bottom portion 13a, and the outer periphery (outer diameter) 13b of the electric cooker body 1 is equal to the outer diameter of the deep pot 5. Even if it is formed at least the same, and more preferably small, and the pan 5 is placed on the electric cooker body 1 and the cooked food is cooked, the cooked food is placed inside the electric cooker body 1. It is configured not to enter. Further, the inner wall 14 constitutes a cylindrical inner periphery 14b that falls from the uppermost part of the outer periphery (outer wall) 13b of the electric cooker main body 1 to the bottom part 14a while entering a predetermined distance radially inward. In the inner periphery 14b, there is a place on the way from the uppermost part to the bottom part 14a of the outer periphery 13b, specifically, a place that is at least the same as the outer diameter of the flat plate 6 or the grilled meat plate 7, and more preferably a place that is radially inner. Even when a stepped portion 14c is formed and a flat plate 6 or a grilled meat plate 7 is placed on the electric cooker body 1 to cook the cooked food, the cooked food remains in the stepped portion 14c. In addition, it is configured not to enter the bottom portion 14a along the inner circumference 14b.
Further, as shown in FIG. 3, the case 8 of the electric cooker main body 1 is disposed on each of the cooking pots 2 to be described later, in particular, the shallower flat plate 6 and the flange portion 15 of the outer diameter of the grilled meat plate 7. A pair of handle storage portions 17 are formed on the circumference of the outer wall 13 and the inner wall 14 in the cylindrical shape so that the pair of handles 16 can be stored. Thereby, even if the flat plate 6 or the grilled meat plate 7 tries to rotate on the electric cooker body 1, the handle 16 comes into contact with the case 8 of the electric cooker body 1 and the planar plate 6 and the grilled meat plate 7 rotate. Can be prevented.
As shown in FIG. 2, the heat shield plate 11 is made of a heat insulating member, is disposed on the bottom portion 13 a of the case 8 constituting the electric cooker body 1 via the support member 9, and is synthesized by heat from the heating unit 4. The case 8 made of resin is prevented from being deformed.
The heating unit 4 includes a heater plate 4a and a sheathed heater 4b. A sheathed heater 4b is embedded in the heater plate 4a, and the heater plate 4a can be heated. The heater plate 4a is made of a metal having good thermal conductivity, and has a gently convex surface 4c on the top. One cooking pan 2 having a pan bottom corresponding to the shape of the convex surface 4c is placed on the heater plate 4a. Can be heated well.

As shown in FIG. 1 to FIG. 3, the plurality of cooking pans 2 are, for example, a deep pan 5 having a deep depth as a first cooking pan, a flat plate 6 having a small depth as a second cooking pan, As a cooking pan, it is constituted by a grilled meat plate 7 having a shallow depth.
The deep pan 5 is manufactured by press working, and the outer diameter is the same as the outer periphery (outer diameter) 13 b of the electric cooker body 1, and more preferably larger than the outer diameter of the flat plate 6 and the grilled meat plate 7. Largely formed.
The flat plate 6 is manufactured by press working, and the outer diameter thereof is formed to be the same as the radial direction position of the step portion 14 c of the inner periphery 14 b of the electric cooker body 1, more preferably smaller. The same outer diameter is formed.
The grilled meat plate 7 is manufactured by die-casting, and the outer diameter thereof is the same as the radial position of the step portion 14c of the inner periphery 14b of the electric cooker body 1, more preferably smaller. The same outer diameter is formed. On the top surface of the pot bottom of the yakiniku plate 7, a wavy convex portion is provided in part.

Each cooking pan 2 is formed such that the bottom surface of the pan bottom is a gentle concave surface so as to make good contact with the convex surface 4c formed on the top surface of the heater plate 4a.
Moreover, as shown in FIG.2 and FIG.4, the flange part 15 is formed in the outer periphery of each cooking pan 2, The pair of handle 16 arrange | positioned facing this radial direction is attached to this flange part 15, respectively. It is attached via a member 18. As the handle 16 of each cooking pot 2, a handle 16 made of a synthetic resin having a common shape is used. One upper convex portion 19 is provided as an upper locking portion at the upper portion of the handle 16, and the lower portion is provided at the lower portion. One downward convex portion 20 is provided as a protruding locking portion. A stacking structure capable of positioning each cooking pan 2 is formed by locking the upper convex portion 19 and the lower convex portion 20 of the handle 16 provided in each cooking pan 2.
In the lower part of the handle 16, in addition to the lower convex part 20, a protruding fixing part 21 is lifted at a radially inner position of the lower convex part 20, and is lifted to a radially outer position of the lower convex part 20 (outer end of the handle 16). The protrusion 22 is provided, and the tip of the mounting member 18 fixed to the flange 15 on the outer periphery of each cooking pan 2 with a bolt or the like is positioned at an intermediate position in the vertical direction on the radially inner side of the downward projection 20. While being fitted to the provided notch 23, the tip of the protruding fixing part 21 is configured to contact the upper surface of the mounting member 18. Thereby, even when the lifting protrusion 22 provided at the lower portion is lifted at the outer end of the handle 16, the fitting between the mounting member 18 and the lower protrusion 20 and the protruding fixing portion 21 and the mounting member 18 By this contact, each cooking pan 2 can be surely lifted or lowered without causing damage to the handle 16.

  The lid member 3 includes a glass lid 30 having a circular shape and a convex cross section, and a resin lid knob 31 provided at a central portion of the upper surface of the lid 30. The lid | cover 30 can close the opening of the upper part of each cooking pan 2 by engaging the outer periphery of the said lid | cover 30 to the lid engaging groove 15a provided inside the flange part 15 of each cooking pan 2. FIG. . Moreover, the upper part 31a of the lid knob 31 is formed as a substantially horizontal surface. The lid 30 engaged with each cooking pan 2 is removed, and the lid 30 is turned over and placed on a desk or the like. Even in this case, the substantially horizontal surface of the lid knob 31 and a surface such as a desk come into contact with each other, and the lid 30 can be made stable. Thereby, foodstuffs, such as vegetables, can be put on the upper surface of the cover 30 turned over, and the convenience in cooking improves.

The stacking structure of the handle 16 of each cooking pan 2 will be described below.
As shown in FIG. 4, when placing the deep pot 5, the flat plate 6, and the grilled meat plate 7 sequentially on the electric cooker body 1, first, the deep pot 5 is placed in the heating unit 4 of the electric cooker body 1. Next, the handle 16 of the flat plate 6 is placed on the convex surface 4c of the heater plate 4a. Therefore, in order to position the deep pan 5 and the flat plate 6 by locking the grips 16, the deep pan 5 and the flat plate 6 are in a state having a predetermined interval and are stacked without contact.
Specifically, the radially outer side 20a of the lower convex part 20 provided at the lower part of the handle 16 of the flat plate 6, and the radial inner side 19a of the upper convex part 19 provided at the upper part of the handle 16 of the deep pot 5 Are brought into contact and locked, and the flat plate 6 is positioned in the deep pan 5. In addition, this downward convex part 20 is formed longer than the upward convex part 19, and the front-end | tip of the downward convex part 20 contacts the upper surface of the handle 16 of the deep pan 5, and supports the weight of the plane plate 6. FIG.
Thereby, the lower convex part 20 of the lower part of the handle 16 provided in the plane plate 6 is radially inner than the upper convex part 19 provided in the upper part of the handle 16 of the deep pot 5 (the center side of the flat plate 6). ), The lateral movement of the cooking pot 2 can be restricted in the immediate vicinity of the pot wall where the two cooking pots 2 may come into contact. Specifically, even if some external force is applied from one handle 16 side of the plane plate 6 to the other handle 16 side and a slight relative movement occurs, the mutual position after the plane plate 6 is placed in the deep pan 5 Since the gap between the two is basically set by the handle 16 on the other handle 16 side, the contact between the two cooking pans 2 can be minimized. Further, even if some large external force is applied from the one handle 16 side of the flat plate 6 to the other handle 16 side, the downward convex portion 20 on the one handle 16 side of the flat plate 6 is not connected to the one handle of the deep pan 5. It is possible to prevent the flat plate 6 from tilting and the pot bottom of the flat plate 6 from coming into contact with the pot wall of the deep pot 5 without getting over the upper convex portion 19 on the 16 side. Similarly, even if some large external force is applied from the one handle 16 side of the plane plate 6 to the other handle 16 side, the radially outer side 20a of the downward convex portion 20 on the other handle 16 side of the plane plate 6 is The deeper plate 5 is locked to the radially inner side 19a of the upper convex portion 19 on the other handle 16 side of the deep pan 5, and the locking position between the lower convex portion 20 and the upper convex portion 19 depends on the flat plate 6 itself. Since gravity acts downward on the flat plate 6, the plate is firmly locked, and even if the flat plate 6 tries to move outward in the radial direction, it cannot be moved easily. It can prevent favorably contacting the pot wall of the pot 5. In particular, since the deep pan 5 and the flat plate 6 are manufactured by pressing and may be formed with relatively low processing accuracy, contact between the deep pan 5 and the flat plate 6 by positioning as described above. It is important to be able to prevent this well.
At this time, the radially outer end of the handle 16 of the deep pan 5 is formed to protrude outward in the radial direction from the radially outer end of the handle 16 of the flat plate 6 (see FIGS. 2 and 3). ) When the cooking pots 2 are positioned on the electric cooker body 1, the cooking pots 2 can be easily removed by lifting the deep cooking pot 5. Further, as described above, if the positional relationship between the handle 16 of the deep pan 5 and the handle 16 of the flat plate 6 is maintained, even when the outer diameter of the deep pan 5 itself is larger than the outer diameter of the flat plate 6 itself, Since the outer ends of the handle 16 of the deep pan 5 and the flat plate 6 do not come to the same outer diameter position, the gap between the outer diameter portion of the flat plate 6 located on the upper side and the handle 16 is reduced, and the flat plate 6 The attachment member 18 provided between the handle 16 and the handle 16 can be prevented from being visually recognized and deteriorating the appearance.

Next, the handle 16 of the yakiniku plate 7 is placed on the top of the handle 16 of the flat plate 6. Therefore, in order to position the flat plate 6 and the grilled meat plate 7 by locking the grips 16, the planar plate 6 and the grilled meat plate 7 are in a state having a predetermined interval and stacked without contact.
Specifically, the radially inner side 20b of the lower convex part 20 provided at the lower part of the handle 16 of the yakiniku plate 7, and the radial outer side 19b of the upper convex part 19 provided at the upper part of the handle 16 of the flat plate 6; Come into contact with each other, and the yakiniku plate 7 is positioned on the flat plate 6. Similarly to the above, the lower convex portion 20 is composed of one convex portion, the upper convex portion 19 is composed of one convex portion, and the lower convex portion 20 is formed longer than the upper convex portion 19. Yes. That is, the handle 16 provided with each cooking pan 2 is formed in the same shape. Here, as shown in FIGS. 2 and 3, the radially outer ends of the grips 16 respectively disposed on the flat plate 6 and the grilled meat plate 7 have the same outer diameter in the radial direction. Since the outer end in the radial direction of 16 is arranged inward in the radial direction from the outer end in the radial direction of the handle 16 arranged in the deep pan 5, the handle 16 and the flat plate of the deep pan 5 are arranged. Even if the stacking structure is different from the engagement with the six grips 16, the flat plate 6 and the grilled meat plate 7 can be positioned in a sufficiently stable state.

  Therefore, even when the three cooking pots 2 are sequentially placed on the electric cooker body 1 and the deep pot 5 and the flat plate 6 manufactured by pressing are included, each cooking pot 2 Can be reliably positioned without contacting each other, and even when the manufacturing cost of the handle 16 is reduced by using a common handle 16, the cooking pans 2 are not processed. Positioning can be ensured.

[Another embodiment]
