  An opening 112 is formed at the upper left corner of the front wall 110. In the opening 112, an infrared transmission unit 112A is disposed. The infrared transmitter 112 </ b> A is used to operate a ventilation fan (not shown) or the like that is linked to the driving of the gas stove 1.

  The electrical board 60 is fixed to the rear surface of the upper portion 102. As shown in FIG. 5, the electric circuit board 60 extends in the left-right direction, and the lower ends 63 </ b> A and 63 </ b> B are formed in two arcs so as not to interfere with the through holes 120 and 125. The electrical board 60 is a single-sided mounting type board, and electronic components are mounted only on the mounting surface 61. The mounting surface 61 is provided with a plurality of LEDs 65A and 65B and a connector 66 to which the terminal portion 51 of the cable 50 energizing the LEDs 65A and 65B is connected.

  The LEDs 65A are arranged in an arc along the lower end 63A on the through hole 120 side. The LEDs 65B are arranged in an arc along the lower end 63B on the through hole 125 side. In the present embodiment, seven LEDs 65A and 65B are provided. The LEDs 65A and 65B are mounted on the mounting surface 61 at positions corresponding to the formation positions of the tube holes 131 and 136 of the light guide portions 130 and 135. When the electrical board 60 is assembled to the panel body 100, the mounting surface 61 comes into contact with the rear surfaces of the light guides 130 and 135, and the rear openings of the cylindrical holes 131 and 136 are closed. The LEDs 65A and 65B are disposed in the tube holes 131 and 136, respectively.

  The connector 66 is disposed approximately diagonally to the left of the LED 65A and diagonally upward to the right of the LED 65B at the approximate center in the left-right direction of the mounting surface 61. The lower portion of the connector 66 is disposed below the LED 65A disposed at the top of the plurality of LEDs 65A. When the terminal portion 51 of the cable 50 is connected to the connector 66, the upper end portion of the terminal portion 51 protrudes from the upper end portion 62 of the electrical board 60. The surface height D of the connector 66 on the mounting surface 61, that is, the length that the connector 66 protrudes forward from the mounting surface 61 is longer than the length L that the light guide portions 130 and 135 extend rearward from the front wall portion 110. Small (see FIG. 3).

  As shown in FIG. 2, the flanged cylinder portion 70 includes a main body portion 71 and a flange portion 76. The main body 71 has a cylindrical shape extending in the front-rear direction. The outer diameter of the main body 71 is smaller than the inner diameters of the through holes 120 and 125 of the panel main body 100, and the inner diameter is larger than the outer diameters of the operation knobs 11, 13, and 14 (see FIG. 3). The main body 71 has two hooks 75 and one engagement portion 74 at three locations in the circumferential direction. The two hooks 75 are hooked on the rear surfaces of the through holes 120 and 125, and hold the flanged cylinder part 70 so as to be rotatable about the axis AX. The engagement portion 74 engages with the engagement piece 37 of the LED operation member 36. In the main body 71, the portions sandwiching the engaging portion 74 from both sides in the circumferential direction extend rearward and make it difficult for the engaging piece 37 to come off. The flange portion 76 protrudes radially outward at the front end portion of the main body portion 71 and is formed in a bowl shape that makes one round in the circumferential direction. The flange portion 76 has a notch-shaped light passage portion 77.

  As shown in FIG. 3, the decorative panel 80 is a plate-like body that is assembled to the front side of the upper portion 102 of the panel body 100. The decorative panel 80 includes two openings 86A and 86B penetrating in the front-rear direction, a plurality of translucent portions 81A and 81B arranged above the respective openings 86A and 86B, and an obliquely upper left portion of the left opening 86B. The window portion 82 is formed. The decorative panel 80 has a substantially rectangular shape when viewed from the front, and includes a slide lock 85 at the upper end. When the decorative panel 80 is assembled to the upper portion 102 of the panel main body 100, the decorative panel 80 is fixed to the panel main body 100 by sliding the slide lock 85 to the right.

  The openings 86A and 86B are formed side by side in the left-right direction. The inner diameters of the openings 86A and 86B are larger than the outer diameters of the operation knobs 13 and 14, respectively. Operation knobs 13 and 14 are disposed in the two openings 86A and 86B, respectively. The translucent portions 81A and 81B are provided at positions corresponding to the formation positions of the light guide portions 130 and 135 when the decorative panel 80 is assembled to the upper portion 102 of the panel main body portion 100. Light emitted from the translucent portions 81A and 81B and the LEDs 65A and 65B and incident from the rear surface via the light guide portions 130 and 135 is guided to the front surface through the inside, and emitted from the front surface to the front. Moreover, the window part 82 passes the infrared rays transmitted from 112 A of infrared transmission parts (refer FIG. 4).

  Next, assembly of the electrical board 60 will be described. As shown in FIGS. 3 and 6, the electrical board 60 is disposed on the rear surface 111 side of the front wall 110 of the panel body 100 with the mounting surface 61 (see FIG. 5) facing forward. The lower end 64A on the right side of the lower end portion 63A of the electrical board 60 is in contact with the protruding portion 114 on the right side of the through hole 120, and the lower end 64B on the left side of the lower end portion 63B is in contact with the protruding portion 114 on the left side of the through hole 125. The electrical board 60 is positioned.

  The connector 66 is disposed in a concave region S (see FIG. 4) formed by the left side surface 132 of the light guide unit 130, the right side surface 137 of the light guide unit 135, and the rear surface 111 of the front wall unit 110. The Therefore, the connector 66 does not contact the left side surface 132 and the right side surface 137 and does not interfere with the light guide portions 130 and 135. The surface height D of the connector 66 is smaller than the length L at which the light guide portions 130 and 135 protrude from the rear surface 111 of the front wall portion 110. Therefore, the connector 66 does not contact the rear surface 111 and does not interfere with the front wall portion 110. The LEDs 65A and 65B are disposed in the tube holes 131 and 136, respectively. Therefore, the mounting surface 61 can come into contact with the rear surfaces of the light guide portions 130 and 135. The electrical board 60 is screwed to the fixing part 113 and assembled to the panel main body part 100. Since the mounting surface 61 is in close contact with the rear surfaces of the light guides 130 and 135, the light emitted from the LEDs 65A and 65B does not leak from the tube holes 131 and 136.

  Since the electrical board 60 is a single-sided mounting type, no electronic components are arranged on the rear surface. The cable 50 electrically connects the controller (not shown) of the gas stove 1 and the electrical board 60. The terminal portion 51 of the cable 50 is connected to the connector 66 in advance before the electrical board 60 is fixed. The cable 50 passes through the gap G between the upper end 62 of the electrical board 60 and the lower surface 116 of the upper wall 115 of the panel body 100 and is drawn out to the rear side of the electrical board 60. The gap G has such a size that the terminal portion 51 of the cable 50 can pass in the vertical direction. Therefore, the terminal part 51 can be attached to or detached from the connector 66 even after the electrical board 60 is assembled to the panel main body part 100.

  The cable 50 from the controller is also wired to an infrared transmitter 112A provided at the left corner of the front wall 110 and an operation panel (not shown) provided at the lower portion 101 of the panel body 100. The cable 50 wired to the infrared transmission unit 112 </ b> A is branched near the terminal unit 51 and is laid on the left side along the lower surface 116 of the upper wall unit 115. The cable 50 wired to the operation panel is branched near the terminal portion 51, laid on the right side along the lower surface 116 of the upper wall portion 115, and hooked on the front end portion 105 </ b> A of the hook portion 105. As a result, the cable 50 does not hang down on the rear surface side of the electrical board 60 and is laid immediately below the lower surface 116, so that, for example, even if boiled juice enters the panel main body 100, it does not easily adhere to the cable 50.

  Further, the cable 50 is laid down along the left surface of the right wall portion 118. The cable 50 is laid in a path that passes between the right wall portion 118 and the guide wall portion 106, and is connected to the operation panel of the lower portion 101. Therefore, the cable 50 is prevented from contacting the operation knob 13 disposed in the through hole 120 or the fuel supply device 20 for the back burner 6.

  As shown in FIG. 3, the fuel supply device 20 for the left burner 5 and the fuel supply device 20 for the back burner 6 are arranged on the left and right sides of the back surface of the panel main body 100 to which the electrical board 60 is assembled. In this state, the mounting bracket 33 is used and fixed with screws. The engagement piece 37 of the LED operation member 36 is engaged with the engagement portion 74 of the flanged cylinder portion 70. Therefore, when the heating power adjustment cam 26 to which the LED operation member 36 is fixed rotates around the shaft center AX, the flanged tube portion 70 rotates around the shaft center AX in the through holes 120 and 125 of the panel body 100. To do.

  All of the LEDs 65A and 65B on the electrical board 60 are lit when the safety valve is opened. As described above, when the operation knobs 13 and 14 are in the operation position, the heating power adjustment cam 26 is connected to the operation knobs 13 and 14, and the rear burner 6 and the left burner 5 are operated according to the turning operation of the operation knobs 13 and 14. You can adjust the firepower. When the operation knobs 13 and 14 rotate, the flanged tube portion 70 rotates around the axis AX together with the heating power adjustment cam 26 via the LED operation member 36. The flange portion 76 blocks the light of the LEDs 65 </ b> A and 65 </ b> B that are irradiated forward through the cylindrical holes 131 and 136 of the light guide portions 130 and 135, except for the position where the flange portion 76 overlaps the light passage portion 77. When the operation knobs 13 and 14 are rotated and the heating power is changed, the light passage portion 77 moves in the circumferential direction around the axis AX, and the light guide portions 130 and 135 that allow light from the LEDs 65A and 65B to pass therethrough. It is changed according to the arrangement in the circumferential direction. The lights of the LEDs 65A and 65B that have passed through the light passage portion 77 are lit and displayed on the surface of the decorative panel 80 through the light transmission portions 81A and 81B corresponding to the light guide portions 130 and 135. Therefore, the panel device 9B can perform thermal power display according to the position where the light of the LEDs 65A and 65B is lit on the surface of the decorative panel 80.

  As described above, the two light guide portions 130 and 135 extend in the front-rear direction with a length L longer than the surface height D of the connector 66. When the electrical board 60 is fixed to the fixing part 113, the light guide parts 130 and 135 face the LEDs 65A and 65B of the electrical board 60, so that the light guide is provided between the mounting surface 61 and the rear surface 111 of the front wall part 110. A gap corresponding to the length in the front-rear direction of the portions 130 and 135 is formed. In addition, since the light guides 130 and 135 are positioned above the edge portions of the adjacent through holes 120 and 125, the adjacent light guides 130 and 135 out of the side surfaces of the two light guides 130 and 135. The left side surface 132 and the right side surface 137 located on the side form a gap in the left-right direction. Therefore, a region S in which the connector 66 can be disposed is formed between the left side surface 132 and the right side surface 137 of the light guide portions 130 and 135 and the rear surface 111 of the front wall portion 110. By mounting the connector 66 on the mounting surface 61 of the electrical board 60 at a position where the connector 66 is disposed in the region S when the electrical board 60 is fixed to the fixing portion 113, the connector 66 is connected to the front wall 110. The electric substrate 60 can be assembled to the panel device 9B without interfering with the light guides 130 and 135. Therefore, the single-sided mounting type electric board 60 can be used as the electric board 60, and the manufacturing cost of the gas stove 1 can be reduced.

  By disposing the LEDs 65A and 65B in the cylindrical holes 131 and 136 of the respective cylindrical bodies constituting the light guide sections 130 and 135, and fixing the electrical board 60 by bringing the mounting surface 61 into contact with the fixing section 113. Further, light leakage from the light guide units 130 and 135 can be suppressed. Moreover, since the light of the LEDs 65A and 65B can be efficiently emitted forward through the tube holes 131 and 136, the recognizability of the thermal power display corresponding to the rotation position of the operation knobs 13 and 14 can be enhanced. .

  When the soup is spilled and enters the panel device 9B when the gas stove 1 is used, the upper wall 115 can prevent the soup from adhering to the electrical substrate 60. In addition, by hooking the cable 50 connected to the connector 66 on the hooking portion 105, the cable 50 can be positioned in the panel device 9B so as to be disposed below the upper wall portion 115. 50 and can be prevented from adhering to the electrical board 60 through the cable 50.

  The connector 66 is close to the upper end portion 62 of the electrical board 60, and a gap G corresponding to the size of the terminal portion 51 of the cable 50 is provided between the upper wall portion 115 and the upper end portion 62 of the panel device 9B. . Therefore, since the terminal portion 51 of the cable 50 can be inserted into and removed from the connector 66 even when the electrical board 60 is fixed to the fixing portion 113, the cable 50 can be easily routed in the gas stove 1.

  Since it can position so that the cable 50 may be laid in the path | route which passes between between the right wall part 118 and the guide wall part 106 in the panel apparatus 9B, it can prevent that the cable 50 contacts the fuel supply apparatus 20. FIG.

For example, as shown in FIG. 7, the assembly structure of the electrical board 60 in the panel main body 100 of the panel device 9B is also applied to the panel main body 200 of the panel device 9A in which the light guide portions 235 are not arranged in an arc shape. it can. The operation knob 11 of the fuel supply device 20 for the right burner 4 is disposed in the through hole 220 on the right side of the panel body 200. The light guide unit 230 for displaying the thermal power of the right burner 4 has the same configuration as that of the light guide unit 130 for displaying the thermal power of the left burner 5, and is arranged in an arc shape above the edge of the through hole 220. On the other hand, the fuel supply device for the grill burner switches the open / close state of the solenoid valve by a plurality of switches. Therefore, the thermal power display of the grill burner is performed by, for example, six LEDs arranged in three rows and two stages, and the light guide portion 235 for the grill burner is also arranged in three rows and two stages. Also in the panel main body 200 having such a configuration, a concave region S is formed by the left side 232 of the light guide 230, the right side 237 of the light guide 235, and the rear surface 211 of the front wall 210. The connector 266 of the electrical board can be disposed in the region S.
