  The present invention relates to a cooking device such as a stationary type or a built-in type induction heating cooking device that is used in a kitchen of a general household or a commercial kitchen.

  Conventionally, the top plate for mounting cooking utensils in this type of cooking device has a top frame that covers the outer periphery of the top plate due to restrictions such as the internal space of the product, especially for stationary types. It is generally mounted directly on the top surface of the main body, and the top plate and the top frame are bonded with an adhesive. However, in the conventional configuration, when the gap between the top frame and the top plate is insufficient, or when water tightness is initially obtained, the adhesive strength is insufficient. By repeatedly adding the weight of cooking utensils filled with ingredients, the adhesive part can not withstand the force and a gap is generated, and water spilled on the top plate from the gap enters the inside of the main body and enters the inside There was a risk of reaching the control circuit and causing failure. For this reason, an underframe that holds the top plate from below is provided, and the top plate is sandwiched and held between the underframe and the top frame, so that even if the adhesive strength is insufficient, there is a gap between the top plate and the top frame. There is an example that prevents the occurrence of (see, for example, Patent Document 1).

  In addition, the top plate and the main body are attached so that the top frame covers the upper end surface of the main body outline, thereby improving the appearance quality and preventing the water from entering the main body.

  FIG. 9 shows a conventional induction heating cooker described in Patent Document 1. As shown in FIG. As shown in FIG. 9, the top plate 41 is sandwiched between the top frame 42 and the under frame 43, and watertightness is secured by the adhesive 44.

A water wall 9 is formed.

  An arm portion 10 extending downward is attached to the lower surface of the underframe 3 by caulking or spot welding, and a burring hole 11 for screw fastening is provided in the arm portion. The arm portion is attached to the under frame 3 so that the arm portion 10 is positioned inside the water blocking wall 9 when the top plate 2 and the main body 1 are attached.

  The main body 1 and the top plate 2 are fixed by fastening with screws 21 through the holes provided in the arm portion 10 and the side plate 6.

  Inside the main body, two induction heating coils 12 are arranged as heating means below the top plate, and below that, a substrate case 14 containing the control board 13 and a roaster unit 15 as a heating cooker are fixed to the bottom plate. Yes.

  The roaster unit 15 is provided with a gap at the top and is attached with a partition plate 16.

  A support shaft 17 that supports the induction heating coil 12 is formed on the upper surface of the partition plate 16 and the substrate case 14, and the induction heating coil 12 is fixed at a predetermined position.

  The induction heating coil 12 is supplied with high frequency power by the control board 13.

  When the board case 14 and the roaster unit 15 are assembled to the main body 1, the end on the side plate 6 side is located on the inner side of the main body 1 from the water blocking wall 9 so that the board case 14 and the roaster unit 15 can be easily dropped vertically from below.

  A substantially L-shaped top plate support 18 is attached to the upper surface of the substrate case 14. As shown in FIG. 4, the top plate support 18 is made of sheet metal, and a second contact surface 19 is formed by narrowing the approximate center of the vertical surface, and a through hole 20 is provided at the approximate center.

  As shown in FIG. 5, the partition plate 16 has an end portion on the side plate 6 side bent upward so as to have a substantially L shape, and is drawn into a position corresponding to the arm portion 10 on the vertical surface by the second contact surface 19. And a through hole 20 is provided at substantially the center thereof.

  When attaching the top plate 2 to the main body 1, as shown in FIGS. 1 and 2, the top plate 2 is lowered from above and the bottom surface of the side frame 5 and the flange surface 8 are in contact with each other. Further, the screw 21 is inserted and fastened at the burring hole 11 of the arm portion 10 through the through hole 20 provided in the top plate support 18 or the partition plate 16.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, consider a case in which water overflows from the pan, which is the cooking object, on the top plate 2 or overflows during cleaning.

  If the water tightness by adhesion is ensured, even if the water reaches the end surface of the top plate 2, the water does not enter the main body.

  However, when troubles such as deformation of the frame parts such as the side frame 5, inadequate adhesion, and peeling due to deterioration of the adhesive 4 b occur, the water reaching the end surface of the top plate 2 is removed from the side frame as shown in FIG. Through the gap between the top plate 2 and the inside of the side frame 5.

  As shown by the arrows in FIG. 1, the infiltrated water flows along the inside of the side frame 5 and the surface of the top plate 2 and flows to the lower surface of the side frame. Water flowing from the lower surface of the side frame 5 to the inside of the main body is guided by the water blocking wall 9 provided on the side plate 6, and flows toward the outside of the main body 1 from the gap between the flange surface 8 and the side frame 5.

  As described above, since water can be prevented from entering the inside of the main body, it is possible to prevent water from adhering to charging parts such as the induction heating coil 12 and the control board 13 and to prevent failure.

  On the other hand, in order to ensure such waterproofness, the water blocking wall 9 must be disposed inside the end portion of the side frame 5, and for that purpose, the width of the flange surface 8 is set to the width of the side frame 5. Need to be bigger.

  Further, when the top plate 2 is attached to the main body 1 during assembly work or maintenance, the arm portion 10 is attached to the under frame 3 so that the arm portion 10 is located on the inner side of the water blocking wall 9 so that the top plate 2 is lowered from above. It is attached.

  Therefore, a gap due to the width of the flange surface 8 is generated between the arm portion 10 and the side plate 6. Here, when the top plate 2 is attached with a gap, when the top plate 2 is tightened from the hole of the side plate 6 to the burring hole 11 of the arm portion 10 through the screw 21, the arm portion 10 is directed outward by the tightening force. It will be deformed.

Therefore, in the present embodiment, as shown in FIG. 3, the top plate support 18 is provided so as to contact the outer surface of the arm portion 10. As a result, when the top plate 2 is attached, when the top plate 2 is tightened from the hole of the side plate 6 to the burring hole 11 of the arm portion 10 through the screw 21, the top plate support tool fixed to the main body with the force with which the arm portion 10 is pulled out. 18 is received and supported, so that the screws can be fastened without the arm portion 10 being deformed, and the mounting of the top plate 2 is completed.

  Further, in the present embodiment, the top plate support 18 is formed with a second contact surface 19 by drawing the substantial center of the vertical surface as shown in FIG. As a result, when the top plate 2 is attached, when the screw 21 is tightened from the hole of the side plate 6 to the burring hole 11 of the arm portion 10, the arm portion 10 is supported by the top plate support 18 and deformation is prevented. 2, the abutment surface 19 abuts against the inner surface of the side plate 6, and the top plate support 18 supports the force with which the side plate 6 is pulled inward, and the gap between the arm 10 and the side plate 6. Is filled with the top plate support 18. By tightening the screws while sandwiching the top plate support 18, the strength near the fastening portion is increased and the screws 21 are prevented from loosening, so that a robust top plate mounting configuration can be realized.

  Further, as shown in FIG. 5, even when the top plate support is formed by deforming the end face of the partition plate 16 into an L shape, a part of the partition plate 16 is interposed between the arm portion 10 and the side plate 6. Since the same mounting configuration can be realized by sandwiching, the same effect can be obtained.

  As described above, even if the width of the flange surface 8 is increased in order to ensure waterproofness, a robust top plate mounting configuration can be realized by interposing the top plate support 18, While being excellent in strength, a cooking device having excellent assembly workability and maintainability can be obtained.

  In the present embodiment, the top plate support 18 is interposed against the distance between the arm portion 10 and the side plate 6, but for example, the arm is formed by cutting out a part of the flange surface 8. The mounting position of the part 10 can be arranged outside the water blocking wall 9 to eliminate the gap. However, the aforementioned waterproofness is lost by cutting out a part of the flange surface 8. Further, it is possible to reduce the distance from the arm portion 10 by drawing the side plate 6, but there is a limit in terms of appearance quality and workability, and the distance from the arm portion 10 is limited regardless of the width of the flange surface 8. It is difficult to lose.

  Moreover, in this Embodiment, although the top-plate support tool 18 is comprised with the sheet metal, the intensity | strength of the top-plate support tool 18 which receives the force which deform | transforms by increasing plate | board thickness from the arm part 10 or the side plate 6 in that case is sufficient. Therefore, the effect of preventing deformation at the time of tightening is enhanced, and a more robust top plate mounting structure can be realized.

  Further, by bending the upper end portion of the top plate support 18 as shown in FIG. 6 to form the tension surface 22, as shown in FIG. 7, it can be pressed against the underframe 3 when the top plate 2 is attached. . As a result, the displacement in the height direction of the through hole 20 and the side plate 6 of the top plate support 18 and the burring hole 11 of the arm portion 10 due to the distortion of the substrate case 14 or the variation at the time of mounting the arm portion 10 or the like. Since the correction is made, it is possible to provide a cooking device excellent in assembly workability and maintainability.

  Since the basic configuration of the second embodiment is the same as that of the first embodiment, the description of the same parts is omitted, and the difference will be mainly described. Also, the same elements as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIG. 8, in the present embodiment, a downwardly protruding collar 31 is provided at the end of the underframe 3.

  The flange 31 has its outer end face raised substantially vertically and a part thereof is brought into contact with the end face of the top board 2 for positioning when the top board is assembled.

  The side frame 5 is attached with the lower surface of the collar 31 and the top plate 2 sandwiched therebetween.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Similar to the first embodiment, consider a case in which water overflows from a pan, which is a cooking target, on the top plate, or water overflows during cleaning.

  When troubles such as deformation of the frame parts such as the side frame, inadequate adhesion, or peeling due to deterioration of the adhesive 4b occur, the water reaching the end surface of the top plate passes through the gap between the side frame 5 and the top plate 2 and It penetrates into the inside of the frame 5.

  The infiltrated water flows along the inside of the side frame 5 and the surface of the top plate 2 as shown by the arrows in FIG. 8, but the water dripped from the end surface of the top plate 2 is received and guided by the eaves 31 arranged directly below. Water is guided to a place where there is no problem even if it flows downward, and is discharged out of the outer shell through a gap in the outer shell of the main body.

  As described above, in the present embodiment, the water infiltrated by the eaves 31 can be flowed to a place where there is no hindrance, and water is prevented from adhering to a charging part such as an induction coil or a power circuit, thereby preventing a failure. can do.

  In addition, by providing the lower flange 31 on the lower surface side of the top plate, the water blocking wall 9 provided on the side plate 6 must be disposed inside the flange 31 in order to ensure waterproofness. It is necessary to make the width of the surface 8 larger than the width of the flange 31. Therefore, as shown in FIG. 8, the top plate support 18 is interposed in the same manner as in the first embodiment, so that the arm portion 10 and the side plate 6 are prevented from being deformed, thereby realizing a robust top plate mounting configuration. .

The cooking device according to the present invention is not limited to the induction heating cooking device, and can be applied as long as the cooking device is provided with a top plate for placing a cooking utensil.
