The fuel supply device of the grill device includes a plurality of switches (not shown) that are switched on and off according to the rotation position of the operation knob 12. The flow rate adjusting unit of the grill device adjusts the thermal power of the grill burner by switching the open / closed state of the plurality of solenoid valves according to the on / off states of the plurality of switches. Therefore, the thermal power display of the grill device is performed by gradually switching the on / off state of the LED provided in the panel device 9A according to the on / off state of the plurality of switches.

On the other hand, in displaying the thermal power of the right burner 4 in the panel device 9A and displaying the thermal power of the left burner 5 and the back burner 6 in the panel device 9B, the fuel supply device 20 rotates the operation knobs 11, 13, and 14. It does not have an encoder that detects the amount. Therefore, the panel devices 9A and 9B do not control to switch the lighting / extinguishing state of the LED according to the rotation positions of the operation knobs 11, 13 and 14. In the present embodiment, the panel devices 9A and 9B transmit the LED light at the positions corresponding to the rotation positions of the operation knobs 11, 13 and 14, and shield the LED light at other positions to display the thermal power.

The panel device 9B will be described with reference to FIGS. 2 to 6. The configuration of the portion related to the thermal power display of the right burner 4 in the panel device 9A is the same as the configuration of the portion related to the thermal power display of the left burner 5 and the back burner 6 in the panel device 9B. Therefore, the configuration of the panel device 9A is assumed to be similar to the configuration of the panel device 9B, and the description thereof will be omitted.

The front flange portion 79 is provided on the front side of the rear flange portion 78.

As shown in FIG. 2, the fuel supply device 20 for the left burner 5 and the fuel supply device 20 for the back burner 6 are arranged side by side on the left and right sides. In the panel main body 50, the through hole 53 for the left burner 5 and the through hole 53 for the back burner 6 are slightly larger than the radial length of the flange portion 76 of the flanged cylinder portion 70 in the left-right direction. Formed apart. Therefore, when the flanged cylinder portion 70 for the left burner 5 and the flanged cylinder portion 70 for the back burner 6 are assembled into the corresponding through holes 53, the flange portions 76 are arranged at overlapping positions. Here, as described above, the rear flange portion 78 and the front flange portion 79 are formed at positions that are staggered in the front-rear direction. Therefore, since the front flange portion 79 of the flanged cylinder portion 70 for the back burner 6 is arranged at the position where it overlaps with the rear flange portion 78 of the flanged cylinder portion 70 for the left burner 5, each flange portion 76 has a flange portion 76. Do not interfere with each other. With this configuration, the fuel supply device 20 for the left burner 5 and the fuel supply device 20 for the back burner 6 can be arranged close to the left and right in the housing 2.

As shown in FIGS. 3 and 6, the decorative panel 80 is a plate-shaped body assembled to the front side of the upper portion 52 of the panel main body portion 50. The decorative panel 80 includes a substrate 81, a panel plate 82, an annular portion 83, and a translucent member 84. The substrate 81 is the main body portion of the decorative panel 80, and the panel plate 82, the annular portion 83, and the translucent member 84 are assembled. The substrate 81 has a substantially rectangular shape when viewed from the front, and is provided with a slide lock 85 at the upper end thereof. When the decorative panel 80 is attached to the upper portion 52 of the panel main body 50, when the slide lock 85 is slid to the right side, the decorative panel 80 is fixed to the panel main body 50.

Two openings 86 penetrating in the front-rear direction are formed in the substrate 81 side by side in the left-right direction. The inner diameter of the opening 86 is larger than the outer diameter of the operation knobs 13 and 14. The operation knobs 13 and 14 are arranged in the two openings 86, respectively. Grooves 87 in which the translucent member 84 is positioned are formed in the upper outer peripheral portions of the two openings 86, respectively. The translucent member 84 is, for example, a member formed of a transparent resin, and supports a plurality of (seven in this embodiment) translucent portions 88 and all of the plurality of translucent portions 88 integrally connected to each other. It has a rod-shaped support portion 89. The translucent portion 88 is a columnar portion extending in the front-rear direction, and has substantially the same length as the thickness of the substrate 81. The translucent portion 88 is provided at a position corresponding to each formation position of the light guide portion 54 when the decorative panel 80 is assembled to the upper portion 52 of the panel main body portion 50. The groove portion 87 of the substrate 81 is formed according to the outer shape of the translucent member 84, and the translucent member 84 is housed in the groove portion 87. In the groove portion 87, the position of the translucent portion 88 penetrates the substrate 81 in the front-rear direction. The translucent portion 88 emits light from the LED 61, guides the light incident from the rear surface through the light guide portion 54 to the front through the inside, and emits the light from the front to the front.

The annular portion 83 has an annular shape, and the inner diameter thereof is larger than the outer diameter of the operation knobs 13 and 14. The annular portion 83 is arranged in the opening 86 of the substrate 81. The annular portion 83 leaks from the light transmitting portion 88 due to diffused reflection or the like among the light emitted from the LED 61 and transmitted through the translucent portion 88, and blocks the light toward the inside of the opening 86.

The panel plate 82 is, for example, a decorative plate in which the rear surface (back surface) of a transparent resin plate is colored. The panel plate 82 opens two round holes 91 at positions corresponding to the openings 86 of the substrate 81. The positions corresponding to each of the transmissive portions 88 are not colored and can transmit the light of the LED 61. The panel plate 82 is attached to the front surface of the substrate 81 with an adhesive or the like after the translucent member 84 and the annular portion 83 are assembled to the substrate 81.

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 side by side, using the mounting bracket 33, and the panel main body 50 of the panel device 9B. It is fixed to the back of the screw with a screw. The engaging piece 37 of the LED operating member 36 engages with the engaging portion 74 of the flanged cylinder portion 70. Therefore, when the thermal power adjusting cam 26 to which the LED operating member 36 is fixed rotates around the axis AX, the flanged cylinder portion 70 rotates about the axis AX in the through hole 53 of the panel main body portion 50.

All of the plurality of LEDs 61 of the display board 60 are turned on when the safety valve is opened. As described above, when the operation knobs 13 and 14 are in the operation position, the thermal power adjusting cam 26 is connected to the operation knobs 13 and 14, and the back burner 6 and the left burner 5 are connected according to the rotation operation of the operation knobs 13 and 14. You can adjust the firepower of. When the operation knobs 13 and 14 rotate, the flanged cylinder 70 rotates around the axis AX together with the thermal power adjusting cam 26 via the LED operating member 36. The flange portion 76 blocks the light of the LED 61 radiated forward through the cylinder hole 55 of the light guide portion 54 except for the position where it overlaps with the light passing portion 77. When the operation knobs 13 and 14 are rotated and the thermal power is changed, the light passing portion 77 moves in the circumferential direction around the axis AX, and the light guide portions 54 through which the light of the LED 61 can pass are arranged in the circumferential direction. It will be changed according to. The light of the LED 61 that has passed through the light passing portion 77 is lit and displayed on the surface of the decorative panel 80 by passing through the translucent portion 88 of the translucent member 84 corresponding to the light guide portion 54. Therefore, the panel device 9B can display the thermal power depending on the position where the light of the LED 61 is lit on the surface of the decorative panel 80.

As shown in FIG. 7, the circumferential width A of the light passing portion 77 of the flanged tubular portion 70 is larger than the circumferential width B of the tubular hole 55 of the light guide portion 54. The reference of the width A and the width B is the position at the center of the cylinder hole 55 in the radial direction of the axis AX. Further, the width A is larger than the width C between the central positions of the cylinder holes 55 of the adjacent light guide portions 54. The width A is such that the end portion of the tubular hole 55 of one light guide portion 54 on the circumferential clockwise side and the tubular hole 55 that is two circumferentially separated from the tubular hole 55 in the circumferential counterclockwise direction. It is approximately the same size as the width D between the side end. Since the width A of the light passing portion 77 satisfies each of the above conditions, the light passing portion 77 exposes one or more and two or less cylinder holes 55 regardless of the position of the flanged cylinder 70. In other words, no matter where the flanged cylinder 70 rotates, the light passing portion 77 always exposes one cylinder hole 55, so that the thermal power display can be reliably performed. The light passing portion 77 may expose two cylinder holes 55 depending on the rotation position of the flanged cylinder portion 70, but does not expose three or more cylinder holes 55. As a result, the light of the LED 61 arranged in the cylinder hole 55 exposed according to the rotation position of the flanged cylinder portion 70 is irradiated to the front of the gas stove 1 through the translucent portion 88 of the decorative panel 80. That is, the panel device 9B pinpoints the flow rate of the gas adjusted by the thermal power adjusting cam 26 according to the rotation amount of the operation knobs 13 and 14, that is, one or two translucent portions 88 of the portion corresponding to the thermal power. You can make it shine. The same applies to the thermal power display corresponding to the rotation amount of the operation knob 11 of the panel device 9A.

As described above, the flanged cylinder portion 70 blocks the light emitted from the LED 61 by the flange portion 76. The light passing portion 77 of the flange portion 76 is formed in a part of the flange portion 76, so that a part of the light from the LED 61 is passed through. Since the flanged cylinder 70 rotates according to the rotation of the operation knobs 11, 13 and 14, the light from the LED 61 is arranged by the light passing portion 77 according to the rotation position of the operation knobs 11, 13 and 14. The light is applied to the front of the panel devices 9A and 9B at the position where the light is generated. That is, the gas stove 1 can indicate the thermal power display corresponding to the rotation position of the operation knobs 11, 13 and 14 by the light passing through the light passing portion 77. As a result, for example, the rotational positions of the operation knobs 11, 13 and 14 can be detected by an encoder or the like, and the thermal power display can be performed without using various parts or the like necessary for indicating the detected positions by LEDs or the like. It can reduce the production cost. Further, the light passing portion 77 passes the light from the LED 61 only to a predetermined portion corresponding to the rotation position of the operation knobs 11, 13, and 14. That is, in the translucent portion 88, only the portion corresponding to the current thermal power shines pinpointly. Therefore, it is possible to provide the gas stove 1 having excellent recognition of the thermal power display with a simple configuration.

The flange portion 76 is formed in a flange shape on the entire circumference except for the light passing portion 77. Therefore, the flange portion 76 can reliably block the light from the LED 61 even if some dimensional error occurs in the arrangement of the LED 61, so that the light from the LED 61 is the decorative panel except for the position of the light passing portion 77. It is possible to prevent leakage to the front side of 80.

The portion of the light from the LED 61 that is radiated forward by the plurality of light guide portions 54 is limited. Further, among the light that has passed through the plurality of light guide units 54, the light has passed through the light guide unit 54 located at a predetermined portion where the light passage unit 77 is arranged according to the rotation positions of the operation knobs 11, 13, and 14. Only the light reaches the translucent part 88, and only the part corresponding to the current thermal power is shined pinpointly. Since the light for which the thermal power display is performed by the translucent portion 88 has the shape of the cylinder hole 55 of the light guide portion 54, the recognition of the thermal power display can be further enhanced.

Of the light from the LED 61, the light that can pass through the cylindrical hole 55 of the cylindrical light guide portion 54 is limited to the light that goes forward. Therefore, the light for which the thermal power display is performed by the translucent portion 88 is suppressed in spreading and the outline is clear, so that the recognition of the thermal power display can be further improved.

The light that passes through the light passing section 77 and reaches the translucent section 88 is the light from the LED 61, which is an independent light source provided corresponding to each of the plurality of light guide sections 54, and therefore is diffused from a single light source. The intensity of light is stronger than that of light. Therefore, since the light for which the thermal power display is performed by the translucent unit 88 is relatively bright, the recognition of the thermal power display can be further enhanced.

No matter which position the operation knobs 11, 13 and 14 rotate, the light passing portion 77 exposes one or two light guide portions 54. Therefore, in the gas stove 1, the light passing portion 77 is located between the two light guide portions 54, the flange portion 76 closes all the light guide portions 54, all the light from the LED 61 is blocked, and the thermal power display is not performed. Can be prevented from becoming.

When the fuel supply devices 20 are arranged side by side, the through holes 53 are separated from each other to the left and right so that the flange portions 76 of the flanged cylinders 70 arranged in the adjacent through holes 53 do not interfere with each other. The device 9B needs to secure a large width. As described above, the panel device 9B can be formed with the through holes 53 close to the left and right by configuring the flange portions 76 so as not to interfere with each other even if they are arranged at overlapping positions in the front-rear direction. Can be made smaller. Further, since the fuel supply device 20 can be arranged close to the left and right in the housing 2, the space occupied by the fuel supply device 20 in the housing 2 can be reduced, and the arrangement layout in the housing 2 can be freely arranged. Liberalization can be enhanced.

When the light from the LED 61 passes through the translucent portion 88, it may go into the opening 86 due to diffused reflection. The annular portion prevents the light leaking from the translucent portion 88 from illuminating the inside of the opening 86, and can enhance the recognition of the thermal power display.

The present invention is not limited to the above embodiment, and various modifications can be made. Seven light guide portions 54 are provided around the upper side of the through hole 53, but the number is not limited to seven. Seven LEDs 61 of the display board 60 are provided according to the number of the light guide portions 54, but the number of LEDs 61 does not necessarily have to match the number of the light guide portions 54, and is smaller than, for example, the number of the light guide portions 54. You may. In this case, for example, the optical path may be formed of a transparent resin or the like, or the light of one LED 61 may be distributed to a plurality of light guide portions 54 by using a light diffusing plate. Further, the light source is not limited to the LED, and another light source such as an organic EL may be used. The light guide portions 54 are arranged at equal intervals in the circumferential direction, but for example, they may be arranged so that the distance increases as the thermal power increases. Further, the light guide portion 54 does not have to be cylindrical, and may have an optical path formed of, for example, a transparent resin or the like.

The panel device 9B displays the thermal power corresponding to each of the two fuel supply devices 20, but one fuel supply device 20 may be independently assembled to display the thermal power, or three or more fuel supply devices 20 may be displayed. It may be assembled to display the thermal power. The flange portion 76 of the flanged cylinder portion 70 is provided in a flange shape on the entire circumference except for the light passing portion 77, but it does not have to be on the entire circumference. Although the light passing portion 77 is formed in a notch shape, it may be formed as a hole portion opened in the flange portion 76, for example. The translucent member 84 of the decorative panel 80 includes seven translucent portions 88 in accordance with the light guide portion 54, but a plurality of translucent portions 88 may not be provided, and for example, one transparent plate may be used.
