  The second extending portion 762 is a portion having a predetermined length in the left-right direction and extending further downward than the first extending portion 761 at a substantially center in the left-right direction of the first extending portion 761. The length of the second extending portion 762 in the left-right direction is shorter than the length of the first extending portion 761 in the left-right direction. The length of the second extending portion 762 in the left-right direction is M2 (see FIG. 6). M2 is shorter than M1. The aforementioned L1 is longer than M2 and shorter than M1.

  The second extending portion 762 includes a pair of lower locking claws 765 and 765 and a fixing hole 763. The pair of lower locking claws 765 and 765 are provided at the substantially center in the left-right direction at the lower end of the second extending portion 762. The fixing hole 763 is a circular hole provided at a substantially central portion in the vertical direction of the right portion of the second extending portion 762. The pan sensor 53 has a metal holder 53A attached to the lower end portion of its shaft portion. The pan sensor 53 is a screw (not shown) provided on the holder 53A by a screw 53B in a state where the shaft portion is sandwiched between the pair of upper locking claws 764 and 764 and the pair of lower locking claws 765 and 765, respectively. It is screwed to the fixing hole 763 through the hole.

  As shown in FIG. 6, the front end portion of the mounting seat 70 is surrounded by the right end 744 of the left side plate portion 74, the upper end 766 of the first extension portion 761, and the left end 754 of the right side plate portion 75. A notch 711 is formed in the portion. The fixing holes 741 and 751 are disposed at positions where the notch 711 is sandwiched between the left and right. The fixing holes 741 and 751 are screw holes for fixing the burner body 50 to the mounting seat 70.

  The projecting portion 80 is a member formed of a metal plate bent at a predetermined width so as to form a stepped portion projecting upward, and is attached to the left side of the mounting seat 70 with respect to the mounting base 60. . The portion protruding above the protruding portion 80 has a predetermined width in the left-right direction, and has a substantially rectangular shape in plan view extending in the front-rear direction at the left and right portions of the housing 2. The protruding portion 80 includes a base portion 81, a wall portion 82, an upper surface portion 83, and a bent portion 84. The base portion 81 is a surface portion that extends substantially horizontally at the lowermost portion of the protruding portion 80. A screw hole (not shown) is provided in a substantially central portion of the base portion 81, and the base portion 81 is screwed to the fixing hole 611 of the mounting base 60 by a screw 91 through the screw hole. The wall portion 82 is a surface portion extending substantially vertically upward from the base portion 81. The upper surface portion 83 is a surface portion that extends substantially horizontally from the upper end of the wall portion 82 to the right. The bent portion 84 is formed by bending the right end of the upper surface portion 83 downward.

  The protruding portion 80 and the wall portion 614 and the upper portion 615 of the mounting base 60 are arranged so as to sandwich the gas burner 5 from side to side. The height of the upper surface portion 83 relative to the upper surface 61 of the mounting base 60 is substantially the same as the height of the upper side portion 615 relative to the upper surface 61 of the mounting base 60. The upper surface portion 83 and the upper portion 615 are disposed below the lower surface of the central recess 32 of the top plate 3 inside the housing 2. When combustion is performed in the gas burner 5, thermal distortion may occur in which a portion of the top plate 3 near the burner opening 4 is distorted by heat. Since the stove 1 includes the upper surface portion 83 and the upper portion 615, the central recess 32 is prevented from being displaced below the upper surface portion 83 and the upper portion 615 due to thermal strain.

  With reference to FIG. 5 and FIG. 7, a procedure for attaching the mounting seat 70, the protrusion 80, and the gas burner 5 to the mounting base 60 will be described. First, the operator fixes each of the ignition electrode 54, the thermocouple 55, and the pan sensor 53 to the first fixing portion 72, the second fixing portion 73, and the third fixing portion 76 of the mounting seat 70.

  Next, the operator inserts the third fixing portion 76 of the mounting seat 70 into the sensor opening 612 of the mounting base 60. Of the third fixed portion 76, the length of the first extending portion 761 in the left-right direction is M2, which is longer than the length L1 of the sensor opening 612 in the left-right direction. On the other hand, the length M3 in the left-right direction of the second extending portion 762 is shorter than L1. For this reason, as shown in FIG. 7, the 2nd extension part 762 is inserted in the sensor opening 612 among the 3rd fixing | fixed parts 76, the 1st extension part 761 is not inserted in the sensor opening 612, and the lower end 761A is a sensor. It abuts on the upper surface 61 corresponding to a position outside the opening 612. At this time, the operator arranges the mounting seat 70 at a position where the rear surface of the second extending portion 762 inserted into the sensor opening 612 is in contact with the rearmost portion of the sensor opening 612.

  Then, the worker positions the fixing hole 623 provided in the upper fixing portion 622 and the fixing hole 741 provided in the left side plate portion 74 so as to overlap in the vertical direction. Further, the worker positions the fixing hole 633 provided in the upper fixing portion 632 and the fixing hole 751 provided in the right side plate portion 75 so as to overlap in the vertical direction. In the present embodiment, the length in the front-rear direction of the sensor opening 612 corresponds to the length in the front-rear direction of the notch 711 of the mounting seat 70. Further, since the second extending portion 762 is inserted into the sensor opening 612 and the position of the mounting seat 70 in the left-right direction is restricted to some extent, the fixing holes 741, 751 can be easily positioned with respect to the fixing holes 623, 633. .

  The mounting seat 70 is placed on the first support portion 62 and the second support portion 63 in a state where the fixing holes 741 and 751 overlap the fixing holes 623 and 633. The mounting seat 70 is supported by the upper fixing portions 622 and 632, and the lower end 761A is in contact with the upper surface 61. The position at is stable. Further, since the lower end 761A contacts the upper surface 61, the position of the third fixing portion 76 in the vertical direction with respect to the upper surface 61 is defined, and the position of the pan sensor 53 with respect to the burner body 50 is stabilized. In this way, the operator can easily align the mounting seat 70 in the vertical direction and the front-rear direction using the sensor opening 612. Moreover, the pan sensor 53 is vertically inserted through the sensor opening 612 by these operations.

  Next, the operator aligns the flange portions 57 and 58 of the lower portion 50 </ b> A of the burner body 50 in order to attach the gas burner 5 to the mounting base 60. First, the operator arranges the burner body 50 above the mounting seat 70 so that the pan sensor 53 is inserted into the center of the burner body 50. The position of the burner body 50 is such that the outer edge of the flange portion 57 contacts the upright portions 742 and 743 of the left side plate portion 74, and the outer edge of the flange portion 58 contacts the upright portions 752 and 753 of the right side plate portion 75. Align. An operator places the burner body 50 on the mounting seat 70 in this state. Thereby, the fixing hole 571 of the flange part 57 is positioned so as to overlap with the fixing hole 623 of the upper side fixing part 622 and the fixing hole 741 of the left side plate part 74 in the vertical direction. Further, the fixing hole 581 of the flange portion 58 is positioned so as to overlap with the fixing hole 623 of the upper side fixing portion 632 and the fixing hole 751 of the right side plate portion 75 in the vertical direction. In the present embodiment, the length in the left-right direction of the notch portion 711 is slightly longer than the length in the left-right direction of the lower portion 50A of the burner body 50 excluding the flange portions 57, 58. For this reason, the burner body 50 is arranged so that the lower portion 50 </ b> A of the burner body 50 is accommodated in the notch 711. Then, the operator screws a screw (not shown) into the fixing hole 571 in the flange portion through the fixing hole 623 in the upper fixing portion 622 and the fixing hole 741 in the left side plate portion 74. Further, the operator screws a screw (not shown) into the fixing hole 581 of the flange portion through the fixing hole 633 of the upper fixing portion 632 and the fixing hole 751 of the right side plate portion 75.

  Next, the operator attaches the protruding portion 80 to the mounting base by screwing the base portion 81 of the protruding portion 80 into the fixing hole 611 of the mounting base 60 using the screw 91. In addition, when the protrusion part 80 is attached with respect to the mounting base 60, since the lower end 841 of the bending part 84 contacts the attachment seat 70 from the upper side, it is controlled that the attachment seat 70 inclines in the front-back direction.

  Next, the operator places the burner head 52 on the upper part of the burner body 50 after arranging the burner head 52 above the burner body 50 so that the pan sensor 53 is inserted in the center of the burner head 52. . Thereby, the mounting of the mounting seat 70, the protrusion 80, and the gas burner 5 to the mounting base 60 is completed.

  As shown in FIG. 8, when the mounting seat 70, the projecting portion 80, and the gas burner 5 are attached to the mounting base 60, each of the pan sensor 53, the ignition electrode 54, and the thermocouple 55 is disposed in the vicinity of the burner body 50. . In FIG. 8, the burner head 52 is not shown in order to make the ignition electrode 54 and the thermocouple 55 easier to see. Since the pan sensor 53, the ignition electrode 54, the thermocouple 55, and the burner body 50 are fixed to the mounting seat 70, which is a single member, compared to the case where these components are mounted on separate mounting mechanisms, Misalignment between parts due to accumulation of tolerances is unlikely to occur. For this reason, since the shift | offset | difference does not arise easily in arrangement | positioning of the pan sensor 53 with respect to the burner main body 50, the ignition electrode 54, and the thermocouple 55, the stove 1 can maintain the ignition performance and various detection performances of the gas burner 5 favorable. Further, by attaching the mounting seat 70 to the mounting base 60, the gas burner 5, the pan sensor 53, the ignition electrode 54, and the thermocouple 55 can be fixed to the mounting base 60 at a time. The stove 1 can reduce the number of parts for attaching the gas burner 5, the pan sensor 53, the ignition electrode 54, and the thermocouple 55 to the mounting base 60, and the manufacturing cost and management cost of the stove 1 are reduced.

  Further, as shown in FIG. 8, in this embodiment, a virtual straight line P indicating the extending direction of the mixing pipe portion 56 connected to the burner body 50 and a virtual straight line Q passing through the fixing hole 571 and the fixing hole 581. The burner body 50 is attached to the mounting base 60 so as to intersect with each other. In the state where the mounting seat 70, the protruding portion 80, and the gas burner 5 are attached to the mounting base 60, the fixing hole 571 is formed so that the fixing hole 741 of the left side plate portion 74 and the fixing hole 623 of the upper fixing portion 622 are in the vertical direction. They are overlapping. In the fixing hole 581, the fixing hole 751 of the right side plate portion 75 and the fixing hole 633 of the upper side fixing portion 632 overlap each other in the vertical direction. Since the fixing holes 741 and 751 are arranged at positions where the notch 711 is sandwiched between the left and right (see FIG. 6), the virtual straight line Q is arranged so as to cross the notch 711 (see FIG. 6). Further, the virtual straight line P and the virtual straight line Q intersect each other inside the notch 711. That is, the lower part 50 </ b> A of the burner body 50 to which the mixing pipe part 56 is connected to the burner body 50 is arranged inside the notch part 711. As described above, the burner body 50 is mounted in a state where the pan sensor 53, the ignition electrode 54, and the thermocouple 55 are accurately arranged with respect to the burner body 50 in a state where the lower part 50A is arranged inside the notch 711. It is stably fixed to 70.

  If the notch 711 is not provided in the mounting seat 70, the mounting seat 70 needs to have a complicated shape in the vertical direction according to the shape of the burner body 50 including the lower portion 50A. If the shape of the mounting seat 70 is complicated, an error may easily occur in the molding of the mounting seat 70. In this case, the accuracy of arrangement of the pan sensor 53, the ignition electrode 54, and the thermocouple 55 fixed to the mounting seat 70 may be lowered. Further, when the shape of the mounting seat 70 is complicated, it is difficult to secure a space for providing the first fixing portion 72, the second fixing portion 73 and the third fixing portion 76 in the mounting seat 70, or the mounting seat to the mounting base 60. There is also a possibility that the installation work of 70 becomes complicated. As shown in FIG. 9, the stove 1 is provided with a notch portion 711 in the mounting seat 70, and a lower portion 50 </ b> A of the burner body 50 is disposed inside the notch portion 711. Since the left side plate portion 74 and the right side plate portion 75 of the mounting seat 70 are supported at an interval of L2 (see FIG. 5) upward from the upper surface of the mounting base 60, the burner has a height in the vertical direction. The main body 50 is accommodated in the space between the mounting base 60 and the mounting seat 70. In this manner, the stove 1 prevents the complication of the shape of the mounting seat 70 by providing the notch portion 711 in the mounting seat 70, so that the pan sensor 53, the ignition electrode 54, and the thermocouple 55 are connected to the burner. The main body 50 can be accurately arranged.

  With reference to FIG. 10, the peripheral part of the burner main body 50 in the state in which the top plate 3 is installed in the upper part of the housing | casing 2 is demonstrated. In FIG. 10, the burner head 52 is not shown in order to make it easy to see the vicinity of the ignition electrode 54. A burner body 50 is disposed inside the burner opening 4 provided in the top plate 3. Inside the electrode insertion portion 334, the ignition electrode 54 is inserted from below the top plate 3 upward. Inside the thermocouple insertion portion 335, a thermocouple 55 is inserted from below the top plate 3 upward.

  When combustion is performed inside the gas burner 5 and the grill cabinet 7, the air necessary for combustion moves from the inside and outside of the housing 2 toward the gas burner 5, thereby generating an air flow toward the gas burner 5. There is. In the present embodiment, the upper surface 31 and the central recess 32 of the top plate 3 are not provided with a gap such as a screw hole, so that the air outside the housing 2 passes through the burner opening 4, the electrode insertion portion 334, and the thermocouple insertion. It may flow to the inside of the housing 2 via the part 335. For example, when combustion is performed in one gas burner 5, air flows from the outside to the inside of the housing 2 through the burner opening 4 corresponding to the other gas burner 5 where combustion is not performed. In this state, when the other gas burner 5 is to be ignited, the mixture flowing out of the burner body 50 at the time of ignition cannot reach the ignition electrode 54 due to the flow of air flowing through the electrode insertion portion 334, and the ignition electrode 54 discharges. Even if the operation is performed, the gas burner 5 may not be ignited. In the present embodiment, the ignition electrode 54 is fixed to the first fixed portion 72 of the mounting seat 70, and the folded portion 722 above the first fixed portion 72 extends substantially horizontally forward. As a result, the gap between the ignition electrode 54 and the burner opening 4 is closed by the folded portion 722. For this reason, the flow of the air flowing between the ignition electrode 54 and the burner opening 4 in the electrode insertion portion 334 is obstructed by the folding portion 722, and the air-fuel mixture flowing out from the burner body 50 easily reaches the ignition electrode 54. In this manner, the stove 1 uses the first fixing portion 72 to reduce the occurrence of poor ignition of the gas burner 5.

  As described above, in the stove 1 according to the present embodiment, the notch 711 is provided in the mounting seat 70, and the burner body 50 is fixed to the mounting seat 70 at a position sandwiching the notch 711 on the left and right. Fixing holes 741 and 751 are provided. Therefore, without complicating the shape of the mounting seat 70 in the vertical direction, the flanges 57 and 58 of the burner body 50 are fixed to the fixing holes 741 and 751 while avoiding interference between the burner body 50 and the mounting seat 70. The burner body 50 can be fixed through fixing holes 571 and 581 provided in the. Since the shape of the mounting seat 70 in the vertical direction is not complicated, the mounting seat 70 has the first fixing portion 72, the second fixing portion 73, and the first fixing portion for fixing the pan sensor 53, the ignition electrode 54, and the thermocouple 55 to itself. Three fixing parts 76 can be provided. In this case, since the pan sensor 53, the ignition electrode 54, the thermocouple 55, and the burner body 50 are all fixed to the mounting seat 70, the tolerances are integrated compared to the case where these components are mounted on separate mounting mechanisms. The position shift between parts due to is difficult to occur. Moreover, since the number of parts for attaching the gas burner 5, the pan sensor 53, the ignition electrode 54, and the thermocouple 55 to the mounting base 60 can be reduced, the manufacturing cost and management cost of the stove 1 are reduced. Furthermore, the work of attaching the gas burner 5, the pan sensor 53, the ignition electrode 54, and the thermocouple 55 to the housing 2 is facilitated. Since the mixing tube portion 56 is connected to the lower part 50A of the burner body 50, the burner body 50 has a height in the vertical direction. Here, in the front end portion of the mounting seat 70, a notch 711 is formed in a portion surrounded by the right end 744 of the left side plate portion 74, the upper end 766 of the first extension portion 761, and the left end 754 of the right side plate portion 75. Is formed. A virtual straight line P indicating the extending direction of the mixing tube portion 56 and a virtual straight line Q indicating the direction connecting the fixing holes 741 and 751 of the mounting seat 70 intersect each other inside the notch 711. That is, the lower part 50 </ b> A of the burner body 50 is disposed inside the notch 711. The mounting base 60 is provided with a first support portion 62 and a second support portion 63 having a height of L2. The left side plate portion 74 and the right side plate portion 75 of the mounting seat 70 are provided with the first support portion 62. Are placed on the upper surface of the upper fixing part 622 and the upper fixing part 632 of the second support part 63, respectively. For this reason, the mounting seat 70 is mounted on the mounting base 60 with an interval L2 upward from the upper surface of the mounting base 60. For this reason, the space which accommodates the burner main body 50 is ensured above the mounting base 60 corresponding to the position where the notch 711 is provided. In this way, the pan sensor 53, the ignition electrode 54, and the thermocouple 55 are arranged with high accuracy with reference to the virtual straight lines P and Q. For this reason, the stove 1 can arrange the pan sensor 53, the ignition electrode 54, and the thermocouple 55 with respect to the burner body 50.

  The mounting seat 70 abuts the lower end 761A of the first extending portion 761 of the third fixing portion 76 against the upper surface 61 corresponding to a position outside the sensor opening 612 of the mounting base 60, and the second extending portion 762 to the sensor opening 612. Are supported by the first support portion 62 and the second support portion 63 in a state of being inserted downward from above. For this reason, the position in the up-down direction of the mounting seat 70 is stabilized. In addition, the mounting seat 70 can be easily aligned in the vertical direction and the front-rear direction. Further, since the lower end 761A contacts the upper surface 61, the position of the third fixing portion 76 in the vertical direction with respect to the upper surface 61 is defined, and the position of the pan sensor 53 with respect to the burner body 50 is stabilized.

  The third fixing portion 76 is formed by being bent downward at the upper end 766 of the first extending portion 761 that is a portion of the mounting seat 70 that is in contact with the notch 711, so that the mounting seat 70 is made of a single metal plate. Can be molded. Moreover, the accumulation | aggregation of the tolerance for every member produced when the pan sensor 53 is fixed to the mounting base 60 using a some member can be excluded, and the position shift of the pan sensor 53 can be reduced.

  When combustion is performed in one of the gas burners 5 and 5, an air flow is generated in a gap in the electrode insertion portion 334 continuous with the burner opening 4 corresponding to the other gas burner 5, and the ignition electrode 54 is used. It may be difficult to ignite the other gas burner 5. In the stove 1, the folded portion 722 at the upper part of the first fixing portion 72 of the mounting seat 70 extends forward substantially horizontally, and the gap between the ignition electrode 54 and the burner opening 4 is closed. For this reason, the flow of the air flowing between the ignition electrode 54 and the burner opening 4 in the electrode insertion portion 334 of the top plate 3 is obstructed by the folding portion 722, and the air-fuel mixture flowing out from the burner body 50 during ignition reaches the ignition electrode 54. Easier to reach. Accordingly, a decrease in the ignition performance of the ignition electrode 54 is prevented.

  In addition, this invention is not limited to the said embodiment, A various change is possible. For example, in the above embodiment, the length M3 between the upper end 766 and the lower end 761A of the first extension portion 761 of the mounting seat 70 is equal to the upper surface 61 of the mounting base 60 and the upper surfaces of the upper fixing portions 622 and 632, respectively. However, M3 may be shorter than L3. Even in this case, the position of the third fixed portion 76 in the front-rear direction and the left-right direction with respect to the sensor opening 612 is restricted by inserting the second extending portion 762 of the third fixed portion 76 into the sensor opening 612. The mounting seat 70 can be positioned with respect to the mounting base 60.

  The third fixing portion 76 includes a first extension portion 761 having a length in the left-right direction of M1, and a second extension portion 762 having a length in the left-right direction of M2. The fixed portion 76 may not include the first extending portion 761 but may include only the second extending portion 762. Even in this case, the position of the third fixing portion 76 in the front-rear direction and the left-right direction with respect to the sensor opening 612 can be regulated by inserting the lower portion of the third fixing portion 76 into the sensor opening 612. Therefore, it is easier to position the mounting seat 70 with respect to the mounting base 60 than when the mounting seat 70 is not provided with a portion inserted through the sensor opening 612.

  Both the electrode insertion part 334 and the thermocouple insertion part 335 may not be provided as a recess continuous with the burner opening 4. For example, the ignition electrode 54 and You may arrange | position in the position corresponding to the installation position of the thermocouple 55. FIG. In this case, if the folding portion 722 closes the gap on the side close to the gas burner 5 in the electrode insertion portion 334, the air-fuel mixture flowing out from the burner body 50 can easily reach the ignition electrode 54. As with the configuration, the occurrence of poor ignition of the gas burner 5 is reduced. Further, if the folded portion 722 extends forward from the upper end of the upright column portion 721, the flow of air flowing between the ignition electrode 54 and the burner opening 4 can be hindered, and therefore does not necessarily have to extend substantially horizontally.

  In the above embodiment, the notch portion 711 is provided at the front end portion of the mounting seat 70 because the angle at which the mixing tube portion 56 is connected to the lower portion 50A of the burner body 50 is relatively gentle. This is to avoid interference between the pipe portion 56 and the mounting seat 70. Accordingly, when the mixing tube portion 56 is connected to the lower portion 50A of the burner body 50 at an angle at which the mixing tube portion 56 extending substantially in the front-rear direction indicated by the virtual straight line P and the front end portion of the mounting seat 70 do not interfere with each other, the mounting seat A notch 711 may be provided at the rear end of 70. In this case, the first fixing portion 72 and the second fixing portion 73 may be provided at the front end portion of the mounting seat 70.

  In the above-described embodiment, the first support portion 62 and the second support portion 63 have a predetermined height, so that the mounting seat 70 is supported at a predetermined interval with respect to the upper surface 61. 70 may be provided with a member that can be spaced a predetermined distance from the upper surface 61.

  The means for igniting the gas burner 5 is not limited to the ignition electrode 54 of the above embodiment, and may be a heater or the like that can ignite an air-fuel mixture containing fuel gas. Moreover, although the stove 1 of the said embodiment is a gas stove provided with the gas burner 5, the various stoves using other fuels including liquid fuels, such as petroleum, may be sufficient, for example.
