Description

  The present invention relates to an electric heating cooker generally called a hot plate or a grill pan.

  In this type of electric heating cooker, a heating device and a cooking plate are installed in an open portion of a resin case body, and a heat shield plate is interposed between the case body and the cooking plate. In this structure, since the charging part of the heating device is present in the open part, it is not preferable that the soup spilled from the cooking plate falls into the open part.

  In addition, when cooking grilled food, since there is no moisture in the cooking plate, the temperature of the cooking plate becomes high enough to cause burns to the user by instantaneous contact. Therefore, it is necessary to prevent the user from touching the cooking plate.

  Therefore, there has conventionally been an electric heating cooker configured to selectively use a dish-shaped cooking plate used when cooking grilled food and a pot-shaped cooking plate used when cooking boiled food.

  Specifically, the cooking plate for pottery is configured to be buried in the open part of the case body. Therefore, a user does not accidentally touch the outer periphery or upper end side of the cooking plate for pottery. On the other hand, the cooking plate for boiled food is configured such that the outer periphery is positioned above and outside the open part of the case body, so that spilled spilled food from the cooking plate for boiled food flows out of the open part of the case body It had been. In addition, since there is usually boiled broth inside the cooking plate for boiled food, the outer periphery and the vicinity of the upper end of the plate do not become hot enough to cause burns to the extent that the user touches them momentarily.

  However, an electric heating cooker that uses a cooking plate for boiled food and a cooking plate for grilled food is expensive because it requires two cooking plates, and when the cooking plate for grilled food is used. Debris of cooking is easily dropped in the open part.

  For this reason, the structure by which both baked goods and boiled dishes are cooked with the cooking plate type | mold for boiled foods is also considered. However, in this configuration, the pottery is cooked at the bottom of the deep cooking plate, so the user needs to insert chopsticks and the like deeply. Therefore, the user easily touches the upper end of the cooking plate with his / her hand when inserting chopsticks or the like onto the cooking plate.

  Therefore, an electric heating cooker has been proposed in which the outer periphery of the cooking plate is positioned above and outside the open part of the case body, and a wire-shaped safety guard is provided along the outer side of the upper end side of the cooking plate. This safety guard is attached by fixing a metal fitting to a boss formed on the overlap portion of the cooking plate, screwing a resin member to the metal fitting, and locking both ends of the guard to the resin member and the metal fitting. (See Patent Document 1).

  According to the electric heating cooker of Patent Document 1, since the outer periphery of the cooking plate is overlapped with the case body, it is possible to prevent the soup from falling into the open portion, and the user touches the cooking plate with the safety guard. This is also prevented. Therefore, the electric heating cooker of patent document 1 can cook both a boiled food and a grilled food with one cooking plate.

JP-A-9-313358

  However, since the electric heating cooker of Patent Document 1 has a resin member for attaching a guard to the overlap portion of the cooking plate, it is difficult to organize the outer peripheral design of the cooking plate, and the resin member is used when cleaning the overlap portion. Was in the way. Furthermore, since the safety guard is integrated with the cooking plate in the electric cooking device of Patent Document 1, the safety guard is an obstacle when cooking and eating boiled food.

  In order to solve these problems, it is conceivable to provide a safety guard separately from the cooking plate. For example, the safety guard 50 shown in FIGS. 7A and 7B is formed using a metal wire, and includes a ring-shaped wire guard 51 along the outside of the upper end side 61 of the cooking plate 60, and a case body. A ring-shaped support ring portion 52 placed on an inner peripheral step portion 64 that forms the open portion 63 of the 62, and a connecting member 53 joined to the circumferential quadrant of the wire guard portion 51 and the support ring portion 52. It consists of. In order to prevent the safety guard 50 from rattling, a claw portion 65 for pressing the support ring portion 52 is formed on the upper side surface of the inner circumferential step portion 64.

  According to the safety guard 50, since it is not necessary to provide a mounting structure on the overlap portion 66 of the cooking plate 60, the outer peripheral design of the cooking plate 60 can be easily assembled, and the cleaning of the overlap portion 66 is also simplified.

  In addition, the connecting member 53 has a crank shape that passes below the overlap portion 66. As shown by a two-dot chain line in FIG. 7B, when the wire guard part 51 is lifted upward, the connecting member 53 is caught on the lower surface of the overlap part 66, and the safety guard 50 is detached together with the cooking plate 60. Therefore, the safety guard 50 can be removed when it gets in the way.

  However, when the safety guard 50 is lifted while being tilted with respect to the horizontal direction, the cooking plate 60 is similarly tilted. For this reason, when there is a food item in the cooking plate 60, the user needs to lift the safety guard 50 straight along with the weighted cooking plate, and the usability of the safety guard 50 is poor.

  Therefore, in view of the above problems, an object of the present invention is to provide an electric heating cooker in which it is not necessary to provide a safety guard mounting structure on the cooking plate and the safety guard can be easily removed.

  In order to achieve the above object, the cooking plate is provided with an open part, a case body having an outer peripheral part surrounding the open part, and a safety guard along the outer side of the upper end side of the cooking plate. In the electric heating cooker located above the outer peripheral portion, the outer peripheral portion of the case body has slits parallel to each other across the cooking plate when viewed from above, and the safety guard is located above and below the slit. The positioning plate is mounted on the outer peripheral portion with the positioning plate inserted into the slit, and the positioning plate is arranged around an axis parallel to the slit with respect to the safety guard. It is attached so that rotation is possible.

  According to the configuration of the present invention, the outer peripheral portion of the case body has slits parallel to each other across the cooking plate as viewed from above, and the safety guard is provided with a positioning plate that is vertically inserted into and removed from the slit. And the positioning plate is placed on the outer peripheral portion in a state of being inserted into the slit, so that the safety guard is placed in the horizontal direction of the safety guard with the positioning plate and the slit in a state of being placed on the outer peripheral portion. The shift movement is prevented. Further, when the safety guard is lifted upward, the positioning plate is extracted from the slit and removed from the outer peripheral portion of the case body. Therefore, the safety guard is removable from the outer peripheral portion, and there is no need to provide a safety guard mounting structure on the cooking plate side. In addition, since the safety guard is detached independently of the cooking plate, it can be easily removed even when the food is in the cooking plate, as compared with the safety guard 50.

  However, the user can easily remove the safety guard because the safety guard can be easily removed. For this reason, when the positioning plate is fixedly attached to the safety guard, when the safety guard is tilted and lifted in the direction perpendicular to the slit with respect to the horizontal, the positioning plate is bent in the slit and caught on the inner wall of the slit, It may happen that the cooking plate is shaken together with the case body. In addition, since the positioning plate has a length in a direction parallel to the slit, it does not usually bend in this direction.

  Therefore, in the present invention, the positioning plate is attached to the safety guard so as to be rotatable around an axis parallel to the slit. According to this configuration, since the slits are parallel to each other across the cooking plate as viewed from above, the positioning plates rotate with respect to the safety guard around the parallel axes. Thereby, even when the safety guard is tilted and lifted in the direction perpendicular to the slit with respect to the horizontal, each positioning plate is extracted from the slit while rotating relative to the safety guard according to the tilt. The positioning plate is prevented from bending in the direction orthogonal to the slit. Therefore, according to this configuration, even if the safety guard is slightly lifted, the positioning plate is prevented from being caught by the inner wall of the slit.

  In the configuration of the present invention, “parallel” is not limited to being completely parallel, and it is sufficient that the slits and the axes are aligned to such an extent that the above-described effects can be obtained. Further, “turnable” is not limited to the positioning plate having a rotation angle of 360 degrees, and any rotation angle corresponding to the assumed inclination angle of the safety guard is sufficient.

  In addition, the safety guard is not limited to the one along the entire upper end side of the cooking plate, and includes, for example, one that is partially missing or recessed along the handle portion of the cooking plate. In addition, the positioning by the slit and the positioning plate only needs to keep the safety guard along the outer side of the upper end side of the cooking plate.

  In the above-described configuration, the safety guard is formed in a ring shape with an axial portion along the slit and a wire-shaped guard portion along the outer side of the upper end side of the cooking plate between the axial portions, and the positioning plate However, it is preferable to employ a configuration wound around the axis portion.

  According to this configuration, since the safety guard is formed in a ring shape with the axial line portion and the wire-like guard portion, it can be easily formed by bending or joining the metal wire. Moreover, since the axial line part is formed in the safety guard, the positioning plate can be wound around here. And since the positioning plate is wound around the axial part along a slit, it is attached so that rotation is possible only by the cutting / bending process of a metal plate. Accordingly, it is not necessary to provide a hinge mechanism for rotating the positioning plate on the safety guard, and the safety guard can be easily formed from an inexpensive material.

  Further, according to this configuration, since the positioning plate can be wound after the axial portion and the guard portion are formed in a ring shape, it is possible to make the shape between the axial portion and the guard portion intricately bent.

  Therefore, the axial portion may have a rising portion that is continuous with the guard portion, and the guard portion may be supported outside the upper end side of the cooking plate by the axial portion and the rising portion. Thereby, it is only necessary to form a slit on the case body side, and it is not necessary to provide a protruding portion or a metal fitting for supporting the guard portion. For this reason, it becomes difficult to limit the design of the case body. Further, since the guard portion serves as the handle portion of the safety guard, it is not necessary to attach a handle member to the safety guard.

  Preferably, if the positioning plate is buried so as to be inserted into the slit, the positioning plate can be hidden from the appearance of the product in use.

  As described above, in the electric heating cooker according to the present invention, the outer peripheral portion of the case body has slits parallel to each other with the cooking plate as viewed from above, and the safety guard is located above and below the slit. Since there is a positioning plate to be inserted and removed and this positioning plate is placed on the outer peripheral portion in a state of being inserted into the slit, there is no need to provide a safety guard mounting structure on the cooking plate, and the safety guard can be removed. Becomes easier. For this reason, the electric cooking device of the present invention is easy to put together the outer peripheral design of the cooking plate, and can easily clean the overlap portion, and the safety guard becomes an obstacle when cooking the boiled food. The user can easily remove it.

  In addition, the electric cooking device of the present invention is mounted so that the positioning plate can rotate about the axis parallel to the slit with respect to the safety guard, so even if the safety guard is lifted slightly slightly, The positioning plate is prevented from being caught on the inner wall of the slit. For this reason, the electric heating cooker of this invention can prevent that a cooking plate is shaken with the case body, and a cooked product is spilled at the time of removal of a safety guard.

  Hereinafter, an electric heating cooker according to the best embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a front view of a main part of the electric heating cooker, and FIG. 2 shows an oblique upper view of the electric heating cooker. As shown in FIGS. 1 and 2, the electric heating cooker includes an open portion 21 where the cooking plate 10 is installed, a case body 20 having an outer peripheral portion 22 surrounding the open portion 21, and an upper end side of the cooking plate 10. 11 and a safety guard 30 along the outside.

  The case body 20 includes a lower case 23 having a bowl shape with a side periphery 23a formed in a bowl shape with an open top, a protective cover 24 formed with an outer flange portion 24a and a peripheral wall 24b covering the side periphery 23a. Have The opening 21 is formed by the peripheral wall 24 b of the protective cover 24 and the bottom of the lower case 23. A space between the outer periphery of the outer flange portion 24a and the outer periphery of the side peripheral portion 23a is closed by the decorative plate 25, and the outer peripheral portion 22 is formed by the side peripheral portion 23a, the outer flange portion 24a, and the decorative plate 25. Yes.

  Between the protective cover 24 and the cooking plate 10, a bowl-shaped heat shield 26 whose upper end is along the edge 24 c of the protective cover 24 is housed. On the bottom of the heat shield plate 26, a heating device 27 is mounted. The bottom 12 of the cooking plate 10 is installed on the heating device 27.

  The cooking plate 10 is formed in a pan-like shape, and the majority of the side peripheral portion 13 in the vertical direction is accommodated in the open portion 21 in a state where the bottom portion 12 is installed on the heating device 27. The upper end side 11 is the upper end of the side peripheral portion 13. The outer periphery 14 of the cooking plate 10 is a drooping wall connected to the lower end of the tapered wall 11a that is inclined downward and outward from the upper end side 11, and is located above the outer flange portion 24a. For this reason, the broth or the like that has spilled over the upper edge 11 falls along the tapered wall 11a and the outer periphery 14 onto the outer flange portion 24a. The upper surface of the outer casing portion 24a is formed so as to fall outward, so that the dropped broth or the like does not flow into the open portion 21.

  FIG. 3 shows a state in which the safety guard 30 is removed in a top view of the electric heating cooker. As shown in FIG. 3, the outer casing portion 24 a of the case body 20 includes slits 40 and 40 that are parallel to each other with the cooking plate 10 interposed therebetween as viewed from above. The slits 40, 40 are formed on the flat surface portion of the outer casing portion 24 a so as to face each other on a symmetry line L passing through the center of the cooking plate 10 as viewed from above, and the length direction thereof is the symmetry line L. It is directed in a direction perpendicular to the direction (see FIG. 1).

  As shown in FIGS. 4 and 5, the inner wall surface of each slit 40 has a shape in which the slit length is narrowed downward from the outer flange portion 24a. A lower end portion of each slit 40 is inserted into a slit plate 42 fixed to the lower case 23 by a screw 41, and is positioned in this state. In the lower case 23, the lower portion of each slit 40 is surrounded by a cylindrical wall 43 that is open at the upper and lower ends, and is open to the outside. Thus, when the slit 40 penetrates the case body 20 up and down and the lower part is opened outside the vessel, even when the broth spills into the outer flange portion 24a and enters the slit 40, the broth etc. It becomes difficult to collect in water, and washing with water becomes easy.

  Positioning plates 31 and 31 attached to the safety guard 30 are inserted into and removed from the slits 40 and 40 above and below.

  The safety guard 30 includes axial portions 32 and 32 that are parallel to each other along the slits 40 and 40, and wire-shaped guard portions 33 and 33 that extend slightly outside the upper end side 11 of the cooking plate 10 between the axial portions. It is formed in a ring shape. The axial portions 32 and 32 have rising portions 34 and 34 that are continuous with the guard portions 33 and 33. A metal wire is used as the material for the safety guard 30.

  The inner periphery of the safety guard 30 is provided larger than the outer periphery 14 of the cooking plate 10 as shown in FIGS. Thereby, the safety guard 30 can be placed or lifted on the outer casing 24a by being moved up and down so as to fit on the outside of the cooking plate 10.

  Each positioning plate 31 is attached to the safety guard 30 so as to be rotatable around an axis parallel to the slit 40. Specifically, each positioning plate 31 is formed of a metal plate, and is wound around the axial portion 32 from the upper end side. Thereby, each positioning plate 31 can be rotated 360 degrees around the axis portion 32. In order to smoothly rotate the positioning plate 31, the shaft portion 32 is provided with a slight allowance in the axial direction (see FIG. 4).

  When the safety guard 30 is lowered onto the outer flange portion 24a in a state where the axial portions 32, 32 are aligned with the slits 40, 40, the positioning plates 31, 31 are gradually inserted into the slits 40, 40, and eventually the winding portion. Is in contact with the outer flange portion 24a. In this state, the positioning plates 31 and 31 are buried in the slits 40 and 40 except for the winding portion, are in close contact with both sides of the slits 40 and 40 in the slit length direction, and face the gap in the slit width direction with a slight gap. Become. For this reason, the safety guard 30 is placed in a state in which only the ascent can be performed while being prevented from shifting in the horizontal direction by the positioning plates 31 and 31 and the slits 40 and 40. In this placement state, the guard portions 33, 33 are supported by the axial portions 32, 32 and the rising portions 34, 34 so as to be slightly along the outside of the upper end side 11 of the cooking plate 10 (see FIG. 6). Therefore, even when cooking the pottery with a deep-bottomed cooking plate such as the cooking plate 10, the user's hand into which chopsticks or the like can be inserted obliquely from above is before the upper end side 11 of the cooking plate 10 is touched. It comes to contact the guard parts 33 of the safety guard 30. This prevents burns when cooking the pottery.

  In addition, in this electric heating cooker, when the user inserts the positioning plates 31 and 31 into the slits 40 and 40, the user can obtain a feeling that the positioning plates 31 and 31 are firmly inserted. Specifically, as shown in FIGS. 4 and 5, the slit plate 42 has tongue pieces 44a and 44b on both sides in the slit length direction of the slit portion, and the side edge of the positioning plate 31 is the tongue piece 44a, 44b is pushed downward to be elastically deformed.

  Then, when the user raises the safety guard 30 and tries to extract the positioning plates 31 and 31 from the slits 40 and 40, the safety guard 30 is horizontal with respect to the horizontal direction as shown by a two-dot chain line in FIG. As a result, each positioning plate 31 rotates with respect to the safety guard 30 around the axis portion 32 when tilted in a direction orthogonal to the slits 40, 40. Thus, each positioning plate 31 is extracted from the slit 40 while rotating relative to the safety guard 30 according to the inclination of the safety guard 30. For this reason, even if the safety guard 30 is slightly lifted, each positioning plate 31 is prevented from bending in the direction orthogonal to the slit 40, and as a result, each positioning plate 31 is prevented from being caught on the inner wall of the slit 40. Is done.
