  As shown in FIG. 1, the upper end portion of the cooker main body 14 extends in a directly upward direction, and is bent outward at a right angle to form a flange portion 18 extending horizontally toward the outer peripheral side of the opening 13. Has been. The flange portion 18 may not have a continuous shape around the entire circumference. And when the cooking appliance main body 14 is dropped in the opening part 13, it becomes the structure by which the flange part 18 is hooked and supported by the periphery of the opening part 13. FIG.

On the other hand, the frameless top plate 15 is made of, for example, tempered heat-resistant glass and is formed in a flat rectangular plate shape.
The flat upper surface of the top plate 15 can be used as a mounting surface for heating the cooking container such as a pan, and an optimum position display for heating the cooking container is given. As shown, it is formed as a heating unit 19 printed in a circular frame shape. Therefore, the induction heating coil (not shown) provided in the cooker main body 14 described above is disposed on the back side corresponding to the two heating portions 19.

In addition, at two locations near the rear end of the top plate 15, rectangular intake / exhaust ports 20, 20 for intake / exhaust communicating with the inside of the cooker body 14 are formed. Although not shown, a cover member having a large number of ventilation holes is detachably mounted on the upper surface of the intake / exhaust port 20 so as to cover it.
Further, the upper part of the outer peripheral edge portion of the top plate 15 is beveled as particularly shown in FIG. This is a chamfering process by a cutting process. Therefore, an inclined surface part 21 that descends outward is formed in the beveling process at the outer peripheral end part.

  The top plate 15 having such a configuration is connected and fixed to the cooker body 14 via the lower frame 22. The lower frame 22 has a rectangular frame shape having a space corresponding to the opening 13 as a whole, and bent pieces 23 bent vertically in a plurality of positions on the space side hang down and are screwed 24. Thus, the inner surface of the cooker main body 14 is screwed and fixed. On the other hand, the horizontal portion 25 having a frame shape which is a main portion of the lower frame 22 extends in the outer peripheral direction from the void, and is thus formed horizontally toward the outer peripheral side of the opening 13. A bulging portion 26 bulging upward is formed on the outer periphery (outer peripheral edge portion) of the horizontal portion 25. As a result, a spatial space is formed on the back surface side of the bulging portion 26, whereas the upper surface of the bulging portion 26 is in contact with the back surface of the top plate 15. Further, the tip of the outer periphery extends horizontally from the bulging portion 26, and an adhesive 27 such as a silicon adhesive can be stored on the upper surface thereof. The beveled inclined surface portion 21 is provided on the outer peripheral edge portion from the upper portion of the joint portion (adhesive 27) between the top plate 15 and the lower frame 22 to the outer peripheral end portion.

  In a spatial space formed on the back surface side of the bulging portion 26 of the lower frame 22, a flexible rubber waterproof packing 28 made of an independent foam is bonded and fixed with an adhesive (not shown). Yes. Therefore, the top plate 15 and the bulging portion 26 of the lower frame 22 are arranged so as to overlap the top plate 11 via the waterproof packing 28. The waterproof packing 28 is provided continuously over the entire circumference while being bent at the corners of the top plate 15.

  Further, an exterior member 29 is provided on the outer peripheral portion of the waterproof packing 28 and on the substantially entire periphery of the lower portion of the outer peripheral end portion of the top plate 15. The exterior member 29 is made of an elastic body, such as rubber, that is harder than the waterproof packing 28, and has a higher density than the waterproof packing 28, so that dust and the like are less likely to adhere thereto. As shown in FIG. 1, the exterior member 29 has a right-angle shape (corresponding to an inverted L-shape) composed of a bottom wall portion having a horizontal cross-section and a vertical wall portion standing at a right angle. In this state, the back surface of the tip of the lower frame 22 is in contact with the upper surface of the horizontal bottom wall portion, and the outer peripheral end portion of the lower frame 22 is in contact with the inner side of the short side wall portion of the exterior member 29. The lower frame 22 is integrally joined with the adhesive 27. That is, the top plate 15, the lower frame 22, and the exterior member 29 are integrally joined by the adhesive 27, and the outer peripheral end portion of the lower frame 22 is supported by the exterior member 29 in the assembled state.

  In addition, the exterior member 29 is extrusion-molded, and the gap S is likely to be generated between both end portions 30 and 30 formed of one exterior member 29 as shown in FIG. Therefore, in the present embodiment, the both end portions 30 are attached so as to be located at a position where they cannot be seen by the user or the like of the cooking device 12, for example, on the rear side of the cooking device 12.

Here, the means by which the cooking device 12 is dropped into the opening 13 of the top plate 11 and supported and fixed will be described with reference to FIG.
As described above, on the frameless top plate 15 side, the lower frame 22 is preliminarily joined with the waterproof packing 28 and the exterior member 29 in an assembled state, and the lower frame 22 is connected to the cooker body 14 from this state. It is fixed and assembled as a heating cooker 12. And if the cooker main body 14 is dropped in the opening part 13 of the top plate 11 of a kitchen, the flange part 18 will be hooked and supported by the periphery of the opening part 13. FIG. With this configuration, the cooker main body 14 is supported in an assembled state by dropping without the load being directly applied to the top plate 15. At this time, the exterior member 29 is located in the gap between the top surface of the top plate 11 and the back surface of the outer peripheral end of the top plate 15 so as to fill this gap. Further, the waterproof packing 28 positioned inward is held in a sufficiently crimped state between the top plate 11 and the lower frame 22, and the exterior member 29 made of an elastic body is appropriately pressed to generate a gap. Therefore, the cooking device 12 is in the form of being incorporated in the kitchen.

Next, the effect of the heating cooker 12 of the said structure is demonstrated with reference to FIG.
By disposing the exterior member 29 made of an elastic body harder than the waterproof packing 28 in the gap between the upper surface of the top plate 11 and the back surface of the outer peripheral end portion of the top plate 15, dust is collected on the waterproof packing 28 located inward. There is no longer any risk of adhesion. Therefore, the conventional troublesome cleaning work of the waterproof packing 28 is not necessary, and there is no possibility of accidentally damaging the waterproof packing 28 during the cleaning work, and the waterproof effect of the waterproof packing 28 can be maintained for a long time. Furthermore, the exterior member 29 has a good appearance by making it difficult for dust and dirt components to adhere to it, and is easy to clean even if it becomes dirty. Note that the exterior member 29 also has a deterring action for preventing the intrusion of liquid or the like, and a certain waterproof effect can be obtained by the waterproof packing 28 located inside thereof.

Moreover, the structure which provides the waterproof packing 28 in the inner peripheral side of the exterior member 29 as mentioned above is the adhesive which joins the waterproof packing 9 to the top plate 1 like the conventional (refer FIG. 7). There is no risk of protruding to the outer peripheral side seen by the user or the like, and the appearance is further improved.
On the other hand, in an assembled state in the kitchen, the outer peripheral end of the lower frame 22 is supported and fixed on the upper surface of the bottom wall portion of the exterior member 29, and the exterior member 29 itself is sandwiched between the top plate 11 and the top plate 15. It can be held well for a long time in appearance without being easily detached.

Since the adhesive 27 and the exterior member 29 are elastic members, even if a heated cooking container or the like collides with the top plate 15, the impact is absorbed by these elastic members to prevent the top plate 15 from being damaged. it can.
Further, since the bevel process is performed on the upper part of the outer peripheral edge of the top plate 15 and the inclined surface part 21 descending in the outer direction is formed, the rising dimension in the thickness direction at the outer peripheral edge of the top plate 15 is suppressed, and cooking to be heated is performed. A practically safe handling property can be expected, such as making the container difficult to collide when moving and absorbing the impact even if it collides, thus eliminating the possibility of spilling the broth in the pan.

  Although the inclined surface portion 21 of the top plate 15 is thin and has a reduced strength and is easily damaged, the outer peripheral end portion (from the upper portion of the joint portion (adhesive 27) between the top plate 15 and the lower frame 22 ( Since the bevel processing is performed in the range of the outer peripheral edge portion, even if an impact is applied to the inclined surface portion 21, the impact is absorbed by the exterior member 29 provided on the lower side of the top plate 15, the adhesive 27 in the storage state, or the like. The top plate 15 can be reinforced while preventing damage to the top plate 15.

  Moreover, since the both ends 30 and 30 after attachment of the exterior member 29 were located behind the heating cooker 12, even if a gap S was generated between the both ends 30 and 30, the appearance was not impaired. In addition, the exterior member 29 can be adopted from an integral extruded product, and the number of manufacturing and assembling steps can be reduced.

  FIG. 4 to FIG. 6 correspond to FIG. 1 corresponding to the first to third modifications. In the following, the same parts as those in the above embodiment are denoted by the same reference numerals, description thereof is omitted, and different points will be described.

(First modification)
First, FIG. 4 shows a first modification. The difference from the above embodiment is the configuration of the lower frame 41 and the exterior member 42. That is, the lower frame 41 of this modification has no bulging portion 26 and is joined to the top plate 15 via the adhesive 44 applied to a part of the upper surface other than the tip of the horizontal portion 43 of the lower frame 41. Yes. The adhesive 44 is shown by a thick line, but may be the same material as the adhesive 27 of the above embodiment. In addition, the tip of the lower frame 41 has a shape having a horizontal end portion 43a that extends horizontally through a step slightly lower than the horizontal portion 43 portion. Here, the waterproof packing 45 of the present modification is made of the same material as the waterproof packing 28 of the above embodiment, and is similarly provided between the top surface of the top plate 11 and the back surface of the horizontal portion 43 of the lower frame 41.

  The exterior member 42 shown in this modification has a substantially U-shaped cross section with the inner side open, and has a shape that fits and surrounds the tip of the lower frame 41 with respect to the overlapping arrangement of the first modification. The lower frame 41 and the top plate 15 are joined with an adhesive (not shown). In this case, the exterior member 42 may be attached to the lower frame 41 in advance and then joined to the top plate 15, or after the lower frame 41 and the top plate 15 are joined and assembled, the exterior member 42 may be joined. 42 may be fitted to the tip of the lower frame 41 from the side.

  Also in the above configuration, the exterior member 42 is disposed in the gap between the top surface of the top plate 11 and the outer peripheral end portion of the top plate 15, so that the waterproof packing 45 is prevented from being damaged and the appearance is the same as in the above embodiment. It becomes good. In addition, in this embodiment, since the exterior member 42 having a substantially U-shaped cross section is adopted, the horizontal end portion 43a of the lower frame 41 can be temporarily held and the handling at the time of assembly is facilitated. Improvement in workability can be expected.

(Second modification)
FIG. 5 shows a second modification, and the lower frame 41 and the exterior member 46 are the same as the first modification in that the lower frame 41 and the exterior member 46 are different from the lower frame 22 and the exterior member 29 of the above embodiment. Therefore, the second modification is particularly similar to the first modification, and differences from the first modification will be described here. That is, the lower frame 41 of the first modification has a step-shaped horizontal end 43a, whereas in the second modification, the tip of the horizontal end 43a is further bent in the upward direction. The difference is that the standing portion 43b is formed. Accordingly, the exterior member 46 in which the horizontal end portion 43a and the upright portion 43b are housed and held in an engaged state also has a substantially U-shaped cross section in which an upward slit corresponding to the upright portion 43b is added. .

As described above, also in the second modified example, the exterior packing member 46 is disposed in the gap between the top surface of the top plate 11 and the back surface of the outer peripheral end portion of the top plate 15 in the same manner as in the above embodiment. 45 is prevented and the appearance is improved.
In particular, in this modified example, the upright portion 43b is provided at the tip of the horizontal end portion 43a of the lower frame 41 and is configured to engage with the inside of the exterior member 46 in a bowl shape. It can be made more difficult to come off from the frame 41.

(Third Modification)
FIG. 6 shows a third modification, and differs from the second modification in that a recess 43c is provided in the horizontal portion 43 of the lower frame 41. That is, the lower frame 41 of the third modified example is formed with a concave portion 43c having a step that is recessed in a part of the horizontal portion 43 joined to the back side of the top plate 15, and the tip thereof is the second modified example. The horizontal end part 43a and the standing part 43b which went through the level | step difference similarly to are formed.

  However, the recess 43c has a stepped shape as is apparent from the drawing, but the outer peripheral side is open. However, as shown in the figure, in a state where the exterior member 46 is mounted on the lower frame 41, the exterior member 46 is addressed to the outer peripheral side, and the groove-shaped recess 43c is completed. Therefore, the adhesive 47 made of the same material as that of the above embodiment is stored in the recess 43c so as to be bonded and fixed to the top plate 15.

  Thus, according to the present modification, in addition to the second modification, the adhesive 47 is accommodated in the recess 43c, so that the accommodated adhesive 47 does not flow out to the outside and the workability is improved. In addition, the impact can be absorbed by the adhesive 47 even when an impact is applied to the top plate 15 from above.

  The present invention is not limited to the above-described embodiments and modifications shown in the drawings. For example, the upright portion 43b shown in the second and third modifications is bent in a direction other than the upward direction, for example, in the downward direction. You may let them. Moreover, the structure of the recessed part 43c which accommodates the adhesive agent in the horizontal part 43 can also be changed into a seed | species. On the other hand, the exterior member 46 that engages with the outer peripheral end of the lower frame 41 can be variously modified according to the shape of the end of the lower frame 41.
