  FIG. 1 is a perspective view showing the overall configuration of an IH cooking heater incorporating a cooking device according to an embodiment of the present invention as a grill portion. The IH cooking heater 100 shown in the figure is assembled by fitting a housing into an opening of a predetermined size formed in the kitchen counter 200. The IH cooking heater 100 assembled in this way is on the front side. In the upper left part, the front side surface of the heating cooker 1 of this embodiment incorporated as a grill part can be seen.

  The heating cooker 1 is configured such that the inside where the food is placed can be taken out in a drawer-type manner, and the front door of the drawer portion is indicated by reference numeral 1a, but the front door 1a of the drawer portion is below the front door 1a. A laterally long handle 1b is attached to the side so as to project the drawer portion toward the front. In addition, the front door 1a of a drawer | drawing-out part is comprised with transparent heat-resistant glass, and also the heating state of the cooking food cooked inside is coupled with that the interior lamp 41 mentioned later illuminates the heating space 11 Can be observed through the heat-resistant glass of the front door 1a.

  On the upper surface of the IH cooking heater 100 incorporated in the kitchen counter 200, a top plate 103 made of light-transmissive heat-resistant glass is placed. On the top plate 103, two large circular heating area display marks 105, 107 and a circular heating area display mark 109 smaller than or equivalent to the heating area display marks 105, 107 are drawn.

  Inside the IH cooking heater 100, large right and left induction heating coils 105C and 107C (see FIG. 2) are respectively provided directly below these heating area display marks 105 and 107, respectively, and directly below the heating area display mark 109. Is provided with one small central induction heating coil (not shown). Needless to say, the central induction heating coil may be, for example, a radiant heater, or may be an induction heating coil having the same size as the right and left induction heating coils 105C and 107C. The induction heating coil and the radiant heater constitute a heating means. If a cooking utensil such as a pan is placed on these heating area display marks 105, 107, 109, the cooking utensil is heated by an induction heating coil or heater provided immediately below the cooking utensil so that cooking is performed. It has become.

  FIG. 2 is a front view showing the internal structure of the IH cooking heater 100 as viewed from the front side after removing the front cover and the like of the IH cooking heater 100 to show the internal structure of the heating cooker 1 shown in FIG. In FIG. 2, in order to explain the internal structure of the heating cooker 1, the structure of other parts is simplified, and the detailed description thereof is omitted. In the left and right IH inverter chamber 113, a right IH inverter that drives the right and left induction heating coils 105C and 107C, a left IH invar, and the like are provided on the substrate. The grill / central IH inverter chamber 115 is provided with a grill IH inverter 117 for driving an induction heating coil 21 of the grill, which will be described later, a central IH invar 119, and the like on the substrate. Further, a control board 121 for controlling these IH inverters and the like is provided at the lower stage. The fan 111 sucks outside air and cools each of the IH inverters.

  In FIG. 2, the heating cooker 1 of this embodiment located in the lower left is enlarged and shown independently in FIG. 2 and 3, a cooked product 300 such as a fish is placed on a placing net 13 serving as a food placing table in a substantially central portion of the heating space 11 that is a grill box inside the heating cooker 1. ing. This placement net | network 13 is mounted on the upper edge part of the saucer 15 provided in the downward direction. Specifically, a part of the four corners of the peripheral edge of the placement net 13 protrudes downward, and the protrusion protruding downward is placed on the edge 15 a of the peripheral edge of the tray 15.

  In the tray 15, a hot plate 17 as a heating element is placed on a step portion 15 b provided in the middle between the edge 15 a of the peripheral edge and the bottom of the tray 15. As will be described later, the hot plate 17 is heated by an induction heating coil 21 provided below, whereby the cooked food 300 on the placement net 13 is cooked. As will be described later, the hot plate 17 is placed on the step portion 15 b at the peripheral edge of the hot plate 17 without directly contacting the bottom surface of the pan 15, so that the hot plate 17 is separated from the bottom surface of the pan 15. It is provided in the tray 15 in the state where Note that the tray 15 is preferably made of a non-magnetic material such as ceramic, and is difficult to prevent heating by the magnetic field lines of the induction heating coil of the hot plate 17.

  The tray 15 is configured so that it can be pulled out from the front side to the outside while the hot plate 17 and the loading net 13 are placed. This is because, as shown in FIG. 1, the tray 15 is placed on the hot plate 17 or the placement net 13 by pulling out the handle 1b attached under the transparent heat-resistant glass front door 1a of the drawer portion. Can be taken out to the outside from the front side, so that each of the placement net 13, the tray 15 and the hot plate 17 can be individually washed.

  Although the heat plate 17 corresponds to a conventional sheathed heater, the sheathed heater is fixed to the rear portion of the surrounding wall and thus cannot be removed and is difficult to clean. However, in this embodiment, the hot plate corresponding to the conventional heater is used. 17 can be removed and washed. Further, conventionally, since the sheathed heater cannot be removed, the sheathed heater is obstructed, and the dirt on the upper surface, the lower surface, and the side surface of the surrounding wall that is close to the sheathed heater cannot be wiped off. If it removes, there also exists an advantage that the dirt of the upper surface of a surrounding wall, a lower surface, and a side surface can be wiped off easily, and it can improve cleanability and cleanliness.

  Further, the heat plate 17 has a plate-like main body made of a magnetic material, and a protective material that covers the upper and lower surfaces and sides of the plate-like main body of the magnetic material as a whole and protects against rust and the like. It is made of clad material. The magnetic plate-like main body is made of, for example, iron or stainless steel SUS430, and the protective material is made of, for example, stainless steel SUS304, or a cage. Here, the hot plate 17 is formed by punching out three layers of materials of SUS302, SUS430, and SUS302. Since the side surface of the hot plate 17 is relatively thin, it is not necessary to use a protective material on the side surface. The detailed shape of the hot plate 17 will be described later with reference to FIG.

  The surrounding walls 19 are all left and right side walls except for the front side of the heating space 11 of the heating cooker 1, the rear rear wall, the lower bottom, and the upper ceiling so that the heat does not escape from the heating space 11. The tray 15 is provided at the bottom of the surrounding wall 19. In addition, since a flat heater, which will be described later, a so-called flat heater is embedded in the ceiling portion on the upper side of the surrounding wall 19, the ceiling portion is formed by the flat heater embedded in the surrounding wall 19 and the surrounding wall 19. It is what is covered. The bottom 19a of the surrounding wall 19 is made of a non-magnetic material such as ceramic so that it is difficult to prevent heating by the magnetic lines of the induction heating coil of the hot plate 17.

  In addition, an induction heating coil 21 is disposed immediately below the bottom portion 19 a of the surrounding wall 19. The induction heating coil 21 causes the heat plate 17 to be electromagnetically induced through the bottom portion 19 a of the surrounding wall 19 and the bottom portion of the tray 15. The cooked product 300 on the placement net 13 is heated by the heated hot plate 17. Between the induction heating coil 21 and the cooked product 300, the bottom portion 19a of the surrounding wall 19 and the bottom portion of the tray 15 are present under the hot plate 17, both of which are made of a non-magnetic material such as ceramic. It is difficult to prevent the induction heating coil of the hot plate 17 from being heated by the magnetic lines of force, and the bottom 19a of the surrounding wall 19 and the bottom of the tray 15 are hardly heated by the induction heating coil 21 due to the influence of electromagnetic induction or not heated at all.

  The induction heating coil 21 is mounted on a support base 23, and an aluminum magnetic shield plate 25 made of a nonmagnetic material is provided on the lower side of the support base 23. It protects so that the influence of induction does not reach the case of the lower case. In the bottom plate structure below the induction heating coil 21, the bottom plate itself may be made of aluminum. Alternatively, the lower part of the induction heating coil 21 on the bottom plate may be cut out, an aluminum plate may be attached, and only the lower part of the induction heating coil 21 may be made of aluminum.

  A partition member for heat insulation and protection is provided around the surrounding wall 19 constituting the heating space 11 so that the influence of the high temperature of the hot plate 17 heated by the induction heating coil 21 does not reach other parts of the IH cooking heater 100. Of course, there are provided.

  FIG. 4 shows an exploded perspective view of the placement net 13, the hot plate 17, the saucer 15, and the induction heating coil 21 used in the heating cooker 1 shown in FIGS. In FIG. 4, the shapes and structures of the loading net 13, the tray 15, and the induction heating coil 21 are the same as those shown in FIGS.

  As shown in FIG. 4, the heat plate 17 is formed with a plurality of openings 77, and the openings 77 are centered on a substantially rectangular opening 77a at the center and outside the opening 77a. An opening 77b and an opening 77c are formed concentrically, and the radial portion 77d other than these openings 77a, 77b, 77c constitutes the magnetic path of the magnetic flux of the induction heating coil 21, and the ring-shaped portion is induction heated. It is configured to match the winding direction of the coil 21, and serves as a heating element of the hot plate 17.

  Although the hot plate 17 always comes into contact with the oil dripped downward from the cooked product 300 and is kept in contact with the oil, there is a risk of fire. However, openings 77a, 77b, 77c are formed in the hot plate 17, Since a recess is provided in the peripheral edge of the bottom surface and the tray 15 and the hot plate 17 are separated from each other, even if oil or juice falls from the cooked product 300 to the hot plate 17, Since it falls to the receiving tray 15 below from the openings 77a, 77b, 77c, the hot plate 17 does not always contact and heat the dripping material, so that ignition can be suppressed.

  If the heat plate 17 that remains in the ring shape is bent so that both ends of the elongated portion are bent downward or curved in a generally U-shape, dripping from the cooked product 300 is removed. It can make it easy to make it fall to the saucer 15 of a lower part rapidly.

  Note that the shapes of the openings 77a, 77b, and 77c formed in the hot plate 17 shown in FIG. 4 (hereinafter, also simply referred to as the hot plate 17) are examples, and are limited to such shapes. For example, various shapes of openings can be formed by matching the shape of the food placed on the placement net 13 such as fish. That is, the induction heating coil 21 provided below the induction heating coil 21 may also have the shape of the induction heating coil 21 so as to match the shape of the hot plate 17, that is, the opening 77a of the hot plate 17, The induction heating coil 21 is not disposed in the portions corresponding to 77b and 77c, so that the induction heating coil 21 exists only in the portion corresponding to the heat plate 17 of the portion remaining in the ring shape by the formation of the opening 77. It may be configured. Further, the shape of the hot plate 17 and the shape of the induction heating coil 21 may be double, triple, etc. Also, the induction heating coil 21 is formed in a square shape and arranged in the front and back, so that the shape of the hot plate 17 corresponds. You may be made to do.

  FIG. 5 is a perspective view as seen from below the front surface of the heating cooker 1 so that a part of the ceiling and the side wall of the upper surface of the heating cooker 1 shown in FIGS. 2 and 3 can be seen well. As can be seen from the figure, the ceiling 31 on the upper surface of the heating cooker 1 is formed flat, but the ceiling 31 is constituted by a flat heater 33 which is a flat heater. Therefore, for example, even if oil or smoke scattered from the food 300 placed on the placement net 13 adheres to the ceiling 31 and becomes soiled, there is no projection of the sheathed heater as in the conventional case, so cleaning is performed. Can be easily performed.

  As shown in FIG. 5, an interior lamp 41 is attached to the right side wall of the heating space 11 of the heating cooker 1 so as to illuminate the heating space 11 of the heating cooker 1 with the interior lamp 41. In addition, the cooking state and position of the food on the placement net 13 can be easily confirmed.

  As described above, in the heating cooker 1 in which the hot plate 17 and the placement net 13 are provided on the saucer 15 provided at the bottom of the heating space 11, fish or the like is placed on the placement net 13 on the saucer 15. When the food 300 is placed and driven by supplying high-frequency current to the induction heating coil 21 below the saucer 15, the hot plate 17 on the saucer 15 is heated by electromagnetic induction from the induction heating coil 21. 13 is heated from below by the hot plate 17 heated by the induction heating coil 21 and heated from above by the flat heater 33 on the ceiling 31 to be cooked.

  Conventionally, in order to arrange the sheathed heater between the tray and the placement net, it has been necessary to provide a space with a relatively large space, but in the heating cooker 1 of the present embodiment, the heating space 11 Since the induction heating coil 21 is placed on the bottom portion of the heating cooker 1 which is the lower side, and the hot plate 17 is heated by the induction heating coil 21 to heat the food, the tray and the placement net It is not necessary to provide a relatively large space between them, and the placement height of the placement net can be reduced, and the storage height of the cooked food can be increased. Further, when the tray and the placement net are taken out, there is no projection of the sheathed heater as in the conventional case, so that the upper, lower, left and right surfaces of the surrounding wall of the heating space can be easily cleaned.

Moreover, in the heating cooker 1 of this embodiment, since the flat heater 33 is provided above the placing net 13 and the upper surface of the food is heated by the flat heater 33, the placing net and the ceiling surface are conventionally used. Since a sheathed heater is disposed between the two, a relatively large space has to be ensured. However, since this space is not necessary, the height for storing the food can be increased. Of course, an installation space for the induction heating coil 21 and the flat heater 33 is necessary. For example, in the form in which conventional sheathed heaters are arranged vertically, the height of the storage space for the cooked food is 60 to 68 mm. On the other hand, in this embodiment, the width can be increased to 120 mm, which is almost twice as large. As a result, it becomes easy to check the heating state of the cooked food inside, and the cooked food target can be increased so that a thick cooked food can be cooked, and the cooking menu can be expanded.
Moreover, since there is no projection of the sheathed heater in the upper part, the ceiling surface can be easily cleaned, and the heating space 11 can be widened, so that it is easier to clean.

  In particular, the induction heating coil 21 and the heating space 11 of the heating cooker 1 heated by the cooking of the cooked food by heating the hot plate 17 by the induction heating coil 21 described above use the cooling air from the IH cooking heater 100 to the cooling space 11. The induction heating coil 21 can be cooled and the heating space 11 can be smoked by taking in the cooling air taken in from the lower part of the front surface and blowing the introduced cooling air to the induction heating coil 21 and the heating space 11.

  In addition, even when oil, juice, or other drops from the cooked product 300 are dropped downward by the cooking of the cooked product 300 and dropped onto the hot platen 17, the dropped product is formed on the hot platen 17. Since it is made to drop to the saucer 15 below from opening part 77a, 77b, 77c, ignition can be suppressed and adhesion and dirt to a hot platen 17 can be decreased.

  The cooked food 300 on the loading net 13 is heated not only by heating from below with the hot plate 17 using the induction heating coil 21 and heating from above from the flat heater 33 on the ceiling 31, Of course, heating with only one of them can be easily performed with a changeover switch or the like.

  Moreover, in the process which heats the hot plate 17 with the induction heating coil 21 described above, the induction heating coil 21 has a structure in which the influence of electromagnetic induction of the induction heating coil 21 does not reach the case of the lower casing of the induction heating coil 21. It is protected by an aluminum magnetic shield 25 provided on the lower side.

  Furthermore, a receiving space 15, a hot plate 17, a placement net 13, and the like are provided, and the heating space 11 for heating the food on the placement net 13 with the hot plate 17 includes left and right side walls excluding the front side and the rear rear wall. The upper part, the lower bottom part, and the upper ceiling part are all surrounded and covered by the surrounding wall 19 so that the heat of the heating space 11 does not leak to the outside. The saucer 15 is made of ceramic or the like and is not easily affected by the magnetic lines of force of the induction heating coil, so that it is not heated or hardly heated by the electromagnetic induction of the induction heating coil 21.

  In addition, since the tray 15 can be pulled out from the front side while the hot plate 17 and the mounting net 13 are placed, the mounting plate 13, the receiving plate 15 and the hot plate 17 can be washed away. It can be washed easily. Conventionally, since the sheathed heater is fixed, it is difficult to clean the heating member. However, in this embodiment, the hot plate 17 corresponding to the conventional sheathed heater can be detachably removed, so that it can be washed as a whole. The cleaning property can be improved.

  In addition, embodiment is an illustration and the range of invention is not limited to them.
