As described above, since the first contact surface 61 and the second contact surface 62 are flat portions formed by the end surfaces of the plurality of ribs 601, the pushing force of the ignition button 43 is applied to the ignition switch 98. It can be made to act easily.

  With reference to FIG. 6, the mechanism in which the ignition button 43 maintains the basic posture before the ignition operation will be described. The ignition button 43 is inserted into the support frame 80 fixed along the opening 33 of the left front panel 25 from the back side, and the swing shafts 51 and 52 of the ignition button 43 are connected to the axis of each vertical frame portion 82. It is pivotally supported by the support hole 821. Accordingly, the ignition button 43 is supported so as to be swingable inside the support frame 80. In a state where the ignition button 43 is held in the basic posture, the center of gravity of the ignition button 43 is located obliquely forward of the swing shafts 51 and 52. Therefore, in the state of being pivotally supported by the support frame 80, the ignition button 43 naturally swings backward about the swing shafts 51 and 52. Therefore, in a state where the gas supply device 90 is removed, the lower portion is stopped in a posture in which the lower portion is inclined backward with respect to the vertical direction. In the present embodiment, a gas supply device 90 is provided behind the ignition button 43, and the distal end portion of the ignition switch 98 of the gas supply device 90 with respect to the first contact surface 61 of the contact portion 60 of the ignition button 43. Abuts from behind. Therefore, since the ignition button 43 is pushed slightly forward, it is possible to maintain a basic posture in which the finger hook portion 452 is substantially horizontal before the ignition operation.

  The mechanism of the child lock mechanism of the ignition button 43 will be described with reference to FIG. For example, when the lock operation unit 132 is moved to the lock position (rightward position) before the ignition operation, the slide member 13 is moved to the lock position. Then, a pair of protrusions 133 provided on the upper surface of the slide member 13 are respectively arranged behind the pair of locked portions 54 and 55 of the ignition button 43. Thereby, even if the ignition button 43 is pushed, the pair of locked portions 54 and 55 of the ignition button 43 are locked to the pair of protrusions 133 of the slide member 13, so that the pushing operation of the ignition button 43 can be disabled. . Then, when the lock operation unit 132 is moved to the ignition allowable position (left position) in order to release the lock of the ignition button 43, the slide member 13 is moved to the ignition allowable position. Then, the pair of protrusions 133 of the slide member 13 that are locked to the locked portions 54 and 55 of the ignition button 43 are shifted to the left, so that the ignition button 43 can swing. Thereby, pushing operation of the ignition button 43 becomes possible.

With reference to FIGS. 4 to 16, the ignition operation of the left burner 6 by the ignition button 43 will be described. In the present embodiment, description will be given in order of four scenes before the ignition operation, the initial to middle period of the ignition operation, the last stage of the ignition operation to the completion of the ignition operation, and after the ignition operation.
[Before ignition operation]
As shown in FIGS. 4 to 6, the ignition button 43 is held in the basic posture before the ignition operation. At this time, the ignition button 43 is disposed so as to close the opening 33 (see FIGS. 4 and 5). The finger hook portion 452 is in a substantially horizontal state and is disposed at the same position as the handle portion 101 of the grill door 100. The upper inclined surface 451 of the ignition button 43 is disposed to be inclined at the same angle as the upper inclined surface 261 of the left front panel 25. The lower inclined surface 453 of the ignition button 43 is disposed along the inclined shape of the lower portion of the upper inclined surface 261 of the left front panel 25 and the curved shape of the bending portion 263. That is, since the shape of the front portion 45 of the ignition button 43 is arranged so as to follow the shape of the front portion 26 of the left front panel 25, the ignition button 43 is recognized as a part of the left front panel 25 and is simple without unevenness. It is recognized by the user as a simple design. Therefore, the beauty of the front face portion 26 of the left front panel 25 can be improved. Since the upper surface portion 48 of the ignition button 43 is buried and hidden in the opening 33, the user cannot visually recognize the ignition sign portion 481.

[Ignition operation early to mid-term]
As shown in FIG. 6, the user places his / her finger on the finger hooking portion 452 of the ignition button 43 in order to ignite the left burner 6. Since the finger-holding portion 452 in the basic posture is in a substantially horizontal state, the user puts his / her finger on the front end side which is the front side of the finger-hanging portion 452 and pushes it in the diagonally downward direction (push-in direction P). Then, as shown in FIG. 9, the ignition button 43 swings backward about the swinging shafts 51 and 52. Accordingly, the first contact surface 61 of the ignition button 43 pushes the ignition switch 98 backward. At the start of the ignition operation, as shown in FIG. 6, the first contact surface 61 is in contact with the ignition switch 98 so that the pushing force of the ignition button 43 is directly transmitted to the ignition switch 98. easy. When the ignition switch 98 is pushed backward, the spindle 96 is gradually pushed backward against the urging force of the return spring 97. As shown in FIG. 9, when the ignition button 43 swings backward, the upper surface portion 48 that has been hidden inside the opening portion 33 swings forward so that the ignition mark portion 481 is gradually exposed.

  As shown in FIGS. 9 and 10, the finger hook portion 452 swings obliquely downward while drawing an arcuate locus, so that the front end side is gradually inclined downward. Thereby, the user's finger hung on the front end side of the finger hanger 452 starts to slide upward along the finger hanger 452. Furthermore, as the push-in operation of the ignition button 43 proceeds, the push-in direction P is gradually displaced from the obliquely downward direction to the substantially horizontal direction. Moving.

  On the other hand, on the back side of the ignition button 43, as the ignition button 43 swings, the contact position of the contact portion 60 with the ignition switch 98 gradually increases from the first contact surface 61 to the second contact surface 62. Displace (see FIG. 10). Then, the second contact surface 62 gradually rises from the initial stage of the ignition operation, and further pushes the ignition switch 98 backward.

[End of ignition operation to completion of ignition operation]
As shown in FIGS. 11 to 13, at the end of the ignition operation, the upper surface portion 48 further swings forward, so that the ignition mark portion 481 is further exposed. The second contact surface 62 of the ignition button 43 further pushes the ignition switch 98 backward while facing the ignition switch 98. Then, as shown in FIG. 13, the spindle 96 is pushed further rearward, and a gas flow path to the discharge port 102 is opened by a main valve provided in the spindle 96. Since the return spring 97 is greatly compressed, the pushing force of the ignition button 43 necessary to fully open the gas flow path is increased. Here, in this embodiment, when the ignition button 43 and the ignition switch 98 are viewed from the side, the second contact surface 62 of the ignition button 43 is positioned forward and lower than the first contact surface 61. Thereby, the distance L2 (see FIG. 13) between the swing shafts 51 and 52 and the second contact surface 62 (contact position with the ignition switch 98) of the ignition button 43 is the swing shaft at the start of the ignition operation. 51 and 52 and the first contact surface 61 (contact position with the ignition switch 98) is larger than the distance L1 (see FIG. 6). Therefore, in the stove 1, it is easier to apply a large torque to the ignition switch 98 when the ignition operation is completed than when the ignition operation is started. The operation can be performed.

  Further, at the end of the ignition operation, the finger hooking portion 452 is greatly inclined downward compared to the initial stage of ignition. As a result, the position where the force is applied moves to the boundary portion 455 of the finger hooking portion 452, so that the pushing direction P is inclined to an angle close to the horizontal direction. The boundary portion 455 is a boundary portion between the upper inclined surface 451 and the finger hanging portion 452. Here, when the ignition button 43 and the ignition switch 98 are viewed from the side, the virtual straight line Q connecting the boundary portion 455 and the contact position of the ignition switch 98 and the second contact surface 62 is the depression of the ignition button 43. It extends in a direction along the direction P. More specifically, the virtual straight line Q overlaps with the pushing direction P of the ignition button 43. With such a positional relationship, in the stove 1, the pushing force of the ignition button 43 by the user can be directly applied to the ignition switch 98, so that the ignition switch 98 can be pushed down with a light operational feeling.

  Further, as shown in FIG. 13, the second contact surface 62 is in contact with the ignition switch 98 in a state of facing the ignition switch 98 in the pressing direction P when the pressing of the ignition switch 98 is completed. Thereby, the pushing force by the user can be directly applied to the ignition switch 98. Therefore, the ignition switch 98 can be pushed down with a lighter operational feeling.

  When the ignition switch 98 is pushed all the way, the magnet safety valve 99 opens the gas flow path and is kept open by the thermoelectromotive force during combustion of the left stove burner 6. As a result, gas flows from the gas inlet of the valve body 95 into the gas flow path, and is discharged from the discharge port 102 via the gas flow path in the body portion 921. The gas discharged from the discharge port 102 flows into the inlet 6B of the throat portion 6A of the left stove burner 6 and is supplied to the left stove burner 6. At the same time, an igniter (not shown) provided in the vicinity of the left burner 6 is driven to ignite the left burner 6. In this way, the ignition operation of the left stove burner 6 is completed.

[After ignition operation]
When the ignition operation is completed, the user releases his / her finger from the ignition button 43 that has been fully pushed. At this time, since the push of the ignition button 43 in the ignition operation is released, the push-push mechanism moves forward to a predetermined position where the magnet-type safety valve 99 can be closed with the main valve opened, and the ignition switch 98 is locked. Thereby, the combustion state of the left stove burner 6 is maintained. Then, as shown in FIGS. 14 to 16, the ignition button 43 is pushed forward by the ignition switch 98 and slightly swings forward. At this time, a part of the rear end side of the upper surface part 48 is hidden inside the opening part 33, but the ignition mark part 481 maintains a state exposed forward of the opening part 33. By visually recognizing the ignition sign portion 481, the left stove burner 6 is ignited and it can be easily recognized that it is in a combustion state.

  In addition, when extinguishing the left stove burner 6, when the user pushes the ignition button 43 again and releases the finger from the ignition button 43, the ignition switch 98 is unlocked by the push-push mechanism. Then, the spindle 96 is returned to close the main valve. Thereby, supply of the gas to the left stove burner 6 is interrupted, and the left stove burner 6 is extinguished. Since the ignition switch 98 moves forward and returns to the original position, the ignition button 43 swings forward about the swing shafts 51 and 52, and returns to the basic posture where the finger hooking portion 452 is substantially horizontal ( 4 to 6).

  With reference to FIG. 17, the swinging trajectory of the corner portion of the upper surface portion 48 of the ignition button 43 during the ignition operation and the visual effect thereof will be described. As described above, the ignition button 43 is configured to swing backward about the swinging shafts 51 and 52 by the ignition operation, so that the ignition marker portion 481 buried in the opening 33 is exposed to the outside. ing. Here, when the ignition button 43 and the ignition switch 98 are viewed from the side, when the ignition button 43 swings around the swing shafts 51 and 52, the upper surface portion 48 provided with the ignition mark portion 481 and the upper slope are provided. The corner E with the surface 451 moves on the arc-shaped trajectory R. The track R is a circular track whose radius is the distance from the swing shafts 51 and 52 to the corner E. On such a trajectory R, point A is the position of the corner E when projecting forward from the left front panel 25 during the ignition operation. In the present embodiment, the tangential direction T at the point A extends along the upper inclined surface 261 of the left front panel 25. Thereby, the corner | angular part E can be rock | fluctuated so that it may protrude gradually ahead at a shallow angle along the upper inclined surface 261 of the left front panel 25. FIG. That is, the corner E can move along the upper inclined surface 261 of the left front panel 25. Therefore, the stove 1 can prevent the user from giving an impression that the corner E protrudes greatly forward.

  Further, the swing shafts 51, 52 of the ignition button 43 are disposed above the finger hook portion 452, behind the upper inclined surface 261, and below the upper surface portion 48. When the ignition switch 98 is in the ignition state, the boundary portion 455 of the ignition button 43 is in a position buried on the housing 2 side with respect to the upper inclined surface 261 of the left front panel 25 as shown in FIG. Thereby, when the ignition button 43 is swung, the ignition button 43 moves as a whole so as to be buried in the back side of the left front panel 25, so that the impression that the corner E protrudes can be further canceled. Therefore, it is possible to further reduce the sense of protrusion of the ignition mark portion 481.

  In the above description, the left stove burner 6 is an example of the “burner” of the present invention. The left front panel 25 is an example of the “front panel” in the present invention. The ignition button 43 is an example of the “ignition operation unit” in the present invention. The upper inclined surface 261 of the left front panel 25 is an example of the “inclined surface” in the present invention. The boundary portion 455 is an example of the “boundary portion” in the present invention.

  As described above, the stove 1 of the present embodiment includes the gas supply device 90 that supplies gas to the left stove burner 6, and pushes the ignition switch 98 of the gas supply device 90 rearward, whereby the gas supply device 90. The main valve and the magnet type safety valve provided inside are pushed open, and gas can be supplied to the left stove burner 6. A support frame 80 is fixed to the opening 33 of the left front panel 25 of the stove 1, and an ignition button 43 is pivotally supported on the support frame 80 so as to be swingable. The ignition button 43 is disposed on the front side of the gas supply device 90 and is pivotally supported on the support frame 80 by swinging shafts 51 and 52 having axial centers in the left-right direction. The ignition button 43 is swung around the rocking shafts 51 and 52 by an ignition operation, and pushes an ignition switch 98 extending forward from the gas supply device to drive the gas supply device 90, thereby driving the left conburner 6 Ignition or extinguish

  The ignition button 43 includes an upper inclined surface 451 and an upper surface portion 48. The upper inclined surface 451 is provided at least in the upper portion of the front surface portion 45 and is formed so as to be inclined along the upper inclined surface 261 of the left front panel 25. The upper surface portion 48 is connected to the upper end of the upper inclined surface 451, and the ignition switch 98 is buried inside the left front panel 25 when the left stove burner 6 is extinguished. It is formed so as to be exposed to the outside of the panel 25. Such an upper surface portion 48 is provided with an ignition mark portion 481 for indicating the ignition state of the left stove burner 6 to the outside. In such a stove 1, when the ignition button 43 swings, the corner E is the leftmost front panel 25 on the track R drawn by the corner E formed between the upper surface 48 and the upper inclined surface 451. A tangential direction T at a position protruding forward from the top extends along the upper inclined surface 261 of the left front panel 25. Accordingly, the corner E swings so as to gradually protrude forward at a shallow angle along the upper inclined surface 261 of the left front panel 25. Therefore, it is possible to prevent the user from giving an impression that the corner E protrudes greatly forward.

  In addition, this invention is not limited to the said embodiment, A various change is possible. For example, the stove 1 of the above embodiment is a table stove with a grill, but may be a table stove without grease. Moreover, a built-in type stove may be used. The stove 1 includes two stove burners, a right stove burner 5 and a left stove burner 6, but the number of the stove burners is not limited to two, and may be one or three or more.

  In the above embodiment, the ignition button 43 for igniting the left stove burner 6 has been described as an example, but the other ignition buttons 41 and 42 may have the same structure.

  The contact portion 60 of the ignition button 43 according to the above embodiment is formed with a plurality of ribs 601 and is composed of a plurality of ribs 601, but may be a contact portion whose inside is clogged by normal injection molding. In that case, what is necessary is just to comprise the 1st contact surface 61 and the 2nd contact surface 62 with a plane.

  In the above embodiment, the oscillating shafts 51 and 52 are provided on the ignition button 43 and supported by the pair of shaft support holes 821 of the support frame 80 fixed to the left front panel 25.
