A gap is formed. The positioning flange 41 on the periphery of the operating element window hole 131 is fitted into the gap with a gap having a constant width between the positioning flange 41 and the outer periphery of the operating element 31.

  The outer diameter of the positioning flange 41 is set to be substantially the same as the inner diameter of the operation element insertion hole 40. When the positioning flange 41 is fitted along the inner periphery of the operation element insertion hole 40, the switch case 35 is attached to the front panel. 12 is prevented from moving in the direction of the opening surface of the operator window hole 131 along the inner surface 12B. That is, the positioning flange 41 erected along the periphery of the operating element window hole 131 on the inner surface 12B of the front panel 12 and the operating element insertion hole 40 formed on the outer periphery of the operating element 31 in the switch case 35. The switch case 35 serves as a positioning fitting portion and a fitted portion for preventing movement of the operator window hole 131 in the opening surface direction.

  The peripheral edge 42 on the front panel 12 side of the operation element insertion hole 40 is formed in a tapered shape that is reduced in width from the front surface (surface on the front panel 12 side) 35F of the switch case 35 toward the center side of the operation element insertion hole 40. Has been. Accordingly, when the release operation button 23 is assembled to the front panel 12, the positioning flange 41 is smoothly guided to the inside of the operation element insertion hole 40 along the peripheral edge 42 of the operation element insertion hole 40 formed in a tapered shape.

  As shown in FIGS. 2 to 4, a frame portion 43 is formed on the rear surface 35 </ b> B of the switch case 35 so as to surround the outer peripheral end surface of the switch substrate 34 in a substantially rectangular shape. In addition, substantially weight-shaped guide claws 44 that protrude rearward are formed at the upper and lower positions of the frame portion 43 on the rear surface 35B of the switch case 35, respectively.

  The pressing plate 14 is a vertically long and substantially rectangular plate body, and a substantially rectangular frame insertion hole 45 through which the frame portion 43 is inserted is formed at a substantially central position between the upper and lower sides thereof. In addition, circular guide holes 46 through which the guide claws 44 are inserted are provided at the upper and lower positions of the frame insertion holes 45 in the holding plate 14, and the switch case 35 is operated by the frame portion 43 and the guide claws 44. The rotation of the window hole 131 in the circumferential direction is prevented. That is, the frame 43 and the frame insertion hole 45, the guide claw 44 and the guide hole 46, and a rotation blocking unit for blocking the rotation of the switch case 35 in the circumferential direction of the operation element window hole 131. Become. The guide claw 44 and the guide hole 46 are not provided, and the frame portion 43 and the frame insertion hole 45 are configured to prevent the switch case 35 from rotating in the circumferential direction. Alternatively, the frame 43 and the frame insertion hole 45 are not provided, and the guide claw 44 and the guide hole 46 prevent the switch case 35 from rotating in the circumferential direction of the operator window hole 131. It is good also as what was comprised so that.

  The inner periphery of the frame insertion hole 45 is set to be substantially similar to the outer periphery of the frame portion 43, and the frame portion 43 is inserted into the frame insertion hole 45 in the circumferential direction with a predetermined clearance. Yes. Similarly, the inner periphery of the guide hole 46 is set to be larger than the outer periphery of the guide claw 44, and the guide claw 44 is inserted into the guide hole 46 with a predetermined clearance. In other words, the pressing plate 14 is fixed to the front panel 12 in a state in which the shift in the surface direction with respect to the rear surface 35B of the switch case 35 is allowed within a predetermined range.

  Support flanges 121 and 122 that support the pressing plate 14 are extended rearward at the upper edge portion and the lower edge portion of the front panel 12, respectively. On the other hand, a fixing flange 141 that is connected to the upper edge support flange 121 of the front panel 12 extends rearward at the upper edge portion of the pressing plate 14. In addition, a plurality of (here, two) hooking claws 142 that are engaged with the lower edge support flange 122 of the front panel 12 are formed at the lower edge portion of the pressing plate 14.

  The upper edge support flange 121 of the front panel 12 has a plurality of (two in this case) engagement protrusions 51 convex to the lower surface side, and a screw hole for fixing the pressing plate 14 with screws. 52 is formed. On the other hand, the fixing flange 141 of the pressing plate 14 is screwed with a plurality of (in this case, two) engaging holes 53 that are detachably engaged with the engaging protrusions 51 and the pressing plate 14. A screw hole 54 for fastening and fixing is formed. The lower edge support flange 122 of the front panel 12 is formed with a plurality of (here, two) hooking holes 55 for engaging the hooking claws 142 of the pressing plate 14.

  Accordingly, if the engagement hole 53 is engaged with the engagement protrusion 51 in a state where the hook claw 142 is hooked on the hook hole 55, the presser plate 14 is temporarily held by the front panel 12. . In this state, if the screw hole 52 of the front panel 12 and the screw hole 54 of the pressing plate 14 are screwed together with the fixing screw 15, the pressing plate 14 is fixed to the front panel 12.

  As described above, in the mounting structure of the release operation button 23 according to the above embodiment, the pressing plate 14 is fixed to the inside of the front panel 12 of the casing 10, and the switch case 35 is pressed against and supported by the inner side surface 12 </ b> B of the front panel 12. Then, the positioning flange 41 provided on the inner surface 12B of the front panel 12 and the operation element insertion hole 40 of the switch case 35 prevent the movement of the operation element window hole 131 of the switch case 35 in the opening surface direction. Therefore, even if there is a slight shift in the fixing position of the pressing plate 14 with respect to the front panel 12, the operation element 31 is difficult to be displaced from the center of the operation element window hole 131. That is, the operation element 31 is accurately arranged with respect to the operation element window hole 131. Further, since no unnecessary gap is formed between the operating element window hole 131 and the operating element 31, it is difficult for dust, dirt, spillage, etc. to collect around the operating element 31. Accordingly, it is possible to prevent the appearance of the stove 1 from being deteriorated. Furthermore, since it is difficult for the operating element 31 to be caught on the inner peripheral edge of the operating element window hole 131, it is possible to prevent deterioration in operability.

  Moreover, in this case, when the pressing plate 14 is fixed to the inside of the front panel 12, even if the pressing plate 14 is slightly displaced in the surface direction with respect to the rear surface 35B of the switch case 35, the release operation button 23 is Since the front panel 12 is fixed at an appropriate position on the inner side surface 12B, the operation element 31 is arranged more accurately with respect to the operation element window hole 131. Therefore, it is possible to more reliably prevent the appearance and operability of the stove 1 from being lowered.

  In particular, in this case, the positioning flange 41 formed on the inner peripheral edge of the operating element window hole 131 is fitted along the inner periphery of the operating element insertion hole 40 formed on the outer periphery of the operating element 31 in the switch case 35. As a result, the movement of the switch case 35 in the direction of the opening surface of the operating element window hole 131 is prevented, so that the operating element 31 is arranged more accurately with respect to the operating element window hole 131. Therefore, it is possible to more reliably prevent the appearance and operability of the stove 1 from being deteriorated. Further, by forming the positioning flange 41 on the inner peripheral edge of the operator window hole 131 by burring, it is possible to fix another member such as a fixing screw without forming an excessive unevenness on the front panel 12. In addition, since positioning protrusions can be provided on the inner side surface 12B of the front panel 12, it is possible to more reliably prevent the appearance of the stove 1 from being deteriorated, and the structure is not complicated.

  Further, in this case, when the release operation button 23 is assembled to the front panel 12, the positioning flange 41 extends to the inside of the operation element insertion hole 40 along the peripheral edge 42 of the operation element insertion hole 40 formed in a tapered shape. Since it is guided smoothly, the operation element 31 is arranged with higher accuracy with respect to the operation element window hole 131. Therefore, it is possible to more reliably prevent the appearance and operability of the stove 1 from being lowered.

  In this case, if the holding plate 14 is fixed to the inner side of the front panel 12 and the switch case 35 is pressed and supported on the inner side surface 12B of the front panel 12, the frame portion 43, the frame insertion hole 45, and the guide claw 44 and the guide hole 46 prevent the switch case 35 from rotating in the circumferential direction of the operator window hole 131, so that the operator 31 is more accurately arranged with respect to the operator window hole 131. The Therefore, it is possible to more reliably prevent the appearance and operability of the stove 1 from being deteriorated.

  Further, in this case, by engaging the pressing plate 14 with the front panel 12, the release operation button 23 is temporarily held on the inner side surface 12B of the front panel 12, and the pressing plate 14 is then held on the front panel 12. 12, the release operation button 23 is fixed in a state of being pressed against and supported by the inner side surface 12 </ b> B of the front panel 12. Therefore, the operator 31 can be accurately and easily attached to the operator window hole 131. Can be arranged. Accordingly, it is possible to more surely prevent the appearance and operability of the stove 1 from being lowered, and the workability of attaching the release operation button 23 is improved.

  In addition, if the release display lamp 32 is arranged off the center of the display window hole 132, the lighting state of the release display lamp 32 cannot be reliably seen from the front side of the stove 1, and the appearance of the stove 1 may be impaired. Even if the high cut function is canceled, there is a possibility that the high cut function is mistakenly recognized and used. However, in this case, as described above, the positioning flange 41 and the operation element insertion hole 40 prevent the switch case 35 from moving in the opening surface direction of the operation element window hole 131, and the frame portion 43 and the frame insertion hole. 45, the guide claw 44 and the guide hole 46 prevent the switch case 35 from rotating in the circumferential direction of the operator window hole 131. Therefore, the release indicator lamp 32 is also displaced from the center of the display window hole 132. It is difficult to be placed. That is, the release display lamp 32 is accurately arranged with respect to the display window hole 132. Therefore, it is possible to prevent the appearance of the stove 1 from being deteriorated, and to prevent misrecognition of the lighting state of the release display lamp 32.

  In the above embodiment, the positioning flange 41 formed on the inner peripheral edge of the operating element window hole 131 on the inner surface 12B of the front panel 12 is inserted into the operating element insertion formed on the outer periphery of the operating element 31 in the switch case 35. Although what was comprised so that the movement to the opening surface direction of the operator window hole 131 of the switch case 35 was prevented by making it fit in the hole 40, as shown in FIG. The operation of the switch case 35 is performed by fitting the convex portion 401 formed on the outer periphery of the operation element 31 in the switch case 35 into the recess 411 formed along the inner peripheral edge of the operation element window hole 131 in the inner side surface 12B. It is good also as what was comprised so that the movement to the opening surface direction of the child window hole 131 may be prevented. Alternatively, as shown in FIG. 6, a convex portion 402 formed on the outer periphery of the operation element 31 in the switch case 35 is directly fitted inside the operation element window hole 131, so that the operation element window of the switch case 35 is inserted. It is good also as what was comprised so that the movement to the opening surface direction of the hole 131 may be carried out, and as shown in FIG. 7, in the one or several through-hole 413 opened outside the window hole 131 for operation elements, it is good. The switch case 35 is configured to prevent movement of the switch case 35 in the direction of the opening surface of the switch case 35 by inserting one or a plurality of protrusions 403 provided on the outside of the operation element 31. It is also good.

  In the above embodiment, the mounting structure of the release operation button 23 for releasing the high cut function has been described. However, the present invention is directed to the power button for turning on and off the stove 1 and the ignition and extinguishing of the stove burner 2. It can also be applied to mounting structures such as a point-extinguishing operation button for performing cooking, a timer setting operation button for setting a cooking timer, a mode selection operation button for switching cooking modes, and the like.
