  However, since the gas cooker is a cooking utensil, the usage environment is poor, and dirt due to sprayed oil or spilled pots tends to adhere to various places. For this reason, when the illumination structure as disclosed in Patent Document 2 is adopted, if dirt adheres to the back side of the daylighting plate or the operation knob, the light from the light source is blocked by the dirt, and the operation unit is sufficiently There is a risk that it will not be illuminated. Therefore, it is difficult to employ such an illumination structure in a gas cooker. As a result, it has been difficult to improve the operability of the thermal power control device by causing the operation knob to emit light.

  This invention is made | formed in view of such a situation, The objective is to provide the thermal power adjustment apparatus in the gas cooker which can improve operativity by improving the visibility of an operation knob.

An operating knob is provided, and the vicinity of the second end which is the inner side of the cooker main body is provided in the vicinity of the second end of the arm and the arm connected to the throttle valve in a swingable manner. And a translucent member that is provided over both ends of the arm portion and guides light emitted from the light source to emit light from the operation knob.

  According to a second aspect of the present invention, in the thermal power control apparatus for a gas cooker according to the first aspect, the light source is fixed to the arm portion and swings together with the arm portion.

  According to a third aspect of the present invention, in the thermal power control apparatus for a gas cooker according to the first or second aspect, a predetermined gap is provided between the arm portion and the translucent member. The gist.

  In invention of Claim 4, in the thermal-power adjustment apparatus in the gas cooker of any one of Claims 1-3, it has arrange | positioned so that a light source may be enclosed in the light source side end of the said translucent member. The gist is that a curved condensing part is provided.

Hereinafter, the “action” of the present invention will be described.
According to the first aspect of the present invention, the light emitted from the light source is guided to the operation knob by the translucent member provided from the first end portion to the second end portion of the arm portion, and the operation knob emits light. It becomes a state. For this reason, the visibility of the operation knob is improved, and the operability is improved. And the light source is provided in the vicinity of the 2nd end part used as the inner side of a cooking appliance main body. For this reason, dirt or oil stains due to spilling are less likely to adhere to the light source, and light from the light source is prevented from being blocked by the dirt. Moreover, the light emitted from the light source is guided inside the translucent member. For this reason, even if dirt adheres to the surface of the translucent member, the light is reliably guided to the operation knob. Therefore, the operation knob can emit light reliably.

  According to the invention described in claim 2, the light source is fixed to the arm portion and swings together with the arm portion. For this reason, no matter how the arm portion is swung, the brightness of the light emitted from the operation knob is constant.

It becomes difficult to get in between. By the way, when no gap is provided between the arm part and the translucent member, if there is even a slight gap between the arm part and the translucent member, the arm part and the translucent member The liquid enters into the gap due to the surface tension generated between the two. In other words, if no gap is provided between the arm portion and the translucent member, a liquid that causes contamination may infiltrate into the gap unless a slight gap is formed between the two. It becomes easy. For this reason, it is possible to prevent liquid from infiltrating into the gap by positively providing a predetermined gap between the arm portion and the translucent member.

  According to the fourth aspect of the present invention, the light emitted from the light source can be guided with high efficiency by providing the curved light collecting portion surrounding the light source at the light source side end of the translucent member. It becomes possible.

  As described above in detail, according to the present invention, it is possible to provide a heating power adjusting device in a gas cooker that can improve operability by improving the visibility of an operation knob.

Hereinafter, one embodiment which materialized the gas cooker of the present invention as a gas stove is described in detail based on Drawings 1-7.
As shown in FIG. 1, the gas stove 1 according to the present embodiment is a so-called drop-in type gas stove that is mounted in a stove arrangement space provided on a countertop of a kitchen (not shown).

  A top plate 3 made of a heat-resistant glass plate is provided on the top of the stove body 2 as a cooker body constituting the gas stove 1, and a plurality of (here, three) combustion sections 4 are provided on the top plate 3. It has been. And these virtues 5 are installed in these combustion parts 4, respectively.

  As shown in FIG. 2, a grill door 6 for opening and closing a grill portion (not shown) provided in the stove body 2 is provided at the approximate center of the front panel 2 a of the stove body 2. . Further, on both sides of the grill door 6 in the front panel 2a, an ignition operation unit 7 for individually performing the ignition / extinguishing operation of each combustion unit 4 and the grill unit, and the thermal power adjustment of the combustion unit 4 and the grill unit are adjusted. A thermal power control device 11 is provided for each.

  As shown in FIG. 3, an open / close valve mechanism 21 is provided in the stove body 2. The on-off valve mechanism 21 is provided in a gas flow path to the combustion unit 4 and the grill unit, and opens and closes an internal valve body (not shown) by the movement of the valve shaft 22 so that the gas is supplied to the combustion unit 4 and the grill unit. It is a structure for controlling availability. Therefore, various configurations provided in the stove body 2 including such an on-off valve mechanism 21 will be described.

  The on-off valve mechanism 21 has a known structure conventionally used, and has an on-off valve 23 below, and a throttle valve 24 is continuously provided on the upper part thereof. The on-off valve 23 is provided with an inlet 23a, and the throttle valve 24 is provided with an outlet 24a. The gas flowing in from the inflow port 23a flows through the on-off valve 23 and the throttle valve 24, is discharged from the outflow port 24a, and is supplied to the combustion unit 4 and the grill unit.

  The valve shaft 22 is provided at the front portion (front panel 2a side portion) of the on-off valve 23 and is movable between the front panel 2a side and the inside of the stove body 2. In the state where the valve shaft 22 is located on the front panel 2a side (fire extinguishing position), the on-off valve 23 closes the valve body and blocks the gas flow from the inlet 23a to the outlet 24a. To do. In the state where the valve shaft 22 is located on the inside of the stove body 2 (ignition position), the on-off valve 23 opens the valve body to flow gas from the inlet 23a to the outlet 24a. Enable.

  The valve shaft 22 is a mechanism (push push mechanism) that is held at the ignition position when the valve shaft 22 is pressed and moved from the fire extinguishing position to the ignition position, and moves from the ignition position to the fire extinguishing position when pressed at the ignition position. . That is, the valve shaft 22 moves to the fire extinguishing position or the ignition position every time it is pressed. The tip of the valve shaft 22 abuts on the ignition operation unit 7 and moves by a pressing operation of the ignition operation unit 7. For this reason, the on-off valve 23 is opened and closed by a pressing operation of the ignition operation unit 7 via the valve shaft 22.

  On the other hand, the throttle valve 24 has a valve body (not shown) having a pin 24c guided by the inclined cam groove 24b, and adjusts the amount of gas discharged from the outlet 24a by the vertical movement of the valve body. A vertical lever 25 is pivotally supported by a support shaft 25a on the side surface of the throttle valve 24 (the surface on the front side in the drawing). In addition, the pin 24 c is engaged with an upward groove 25 b provided above the vertical lever 25, and the upper end portion is engaged with the arm portion 12 of the thermal power control device 11. A receiving surface 25 d at the lower end of the vertical lever 25 faces the protrusion 22 a of the valve shaft 22.

Next, the structure of the thermal power control apparatus 11 is demonstrated.
As shown in FIGS. 3 to 5, the thermal power adjustment device 11 includes an arm portion 12, an operation knob 13, a light guide 14, and a light source 15.

  The arm portion 12 is configured by a metal plate having a lever shape, and is disposed in a state where the first end portion protrudes to the outside from the front panel 2 a and the second end portion extends inward of the stove body 2. ing. An operation knob 13 is provided at the first end of the arm 12, and the vicinity of the second end (point P 0 shown in FIGS. 4 and 7) is pivotally attached to the upper portion of the throttle valve 24. . For this reason, the operation knob 13 is connected so as to be swingable in the left-right direction shown in FIG. Further, as shown in FIG. 4, a projecting piece 12 a extending in the width direction of the arm portion 12 is formed in the vicinity of the pivoted portion of the arm portion 12. The projecting piece 12a is provided obliquely so as to form a predetermined angle with respect to the direction in which the arm portion 12 extends. The projecting piece 12a is provided with a long hole-shaped hole 12b. The upper end of the vertical lever 25 of the on-off valve mechanism 21 is inserted through the hole 12b. Therefore, when the arm portion 12 is swung left and right, the hole portion 12b of the arm portion 12 moves back and forth, the vertical lever 25 rotates about the support shaft 25a, and the pin 24c slides within the cam groove 24b. Move the valve up and down. For this reason, for example, when the arm portion 12 is swung in the direction of the strong fire position shown in FIG. 7, the vertical lever 25 rotates counterclockwise (arrow A direction shown in FIG. 3) about the support shaft 25a. Rises upward to increase the opening of the gas flow path. On the other hand, for example, when the arm portion 12 is swung in the direction of the low heat position shown in FIG. 7, the vertical lever 25 rotates clockwise about the support shaft 25a, and the valve body rises upward to open the gas flow path. Decrease the degree. Further, when the valve shaft 22 is moved inward of the stove body 2 in accordance with the pressing operation of the ignition operation unit 7, the on-off valve 23 is opened, and the vertical lever 25 is projected by the protrusion 22 a of the valve shaft 22. The receiving surface 25d is pressed, and the throttle valve 24 is moved in the opening direction together with the heating power adjusting device 11.

  Incidentally, the light source 15 is fixed to the second end portion of the arm portion 12. The light source 15 includes a light emitter 15a made of an LED, and the light emitter 15a is disposed so as to face the first end side. For this reason, as shown in FIG. 7, even when the arm portion 12 swings around the point P <b> 0 as a fulcrum, the light emitter 15 a always faces the first end portion side of the arm portion 12.

  A light guide 14 is fixed to the upper portion of the arm portion 12 from the first end portion to the vicinity of the second end portion. The light guide 14 is a translucent member made of polycarbonate or nylon, and is formed narrower than the arm portion 12 as shown in FIG.

  As shown in FIGS. 5 and 6, a pair of protrusions 14 a extending in the same direction as the direction in which the light guide 14 extends are formed on the lower surface of the light guide 14. As shown in FIG. 6, these protrusions 14 a are formed to have a predetermined height C, and the lower surface of the protrusion 14 a is fixed to the upper surface of the arm portion 12, whereby the light guide 14 is moved to the arm portion 12. It is fixed to. For this reason, a gap corresponding to the height C is provided between the upper surface of the arm portion 12 and the lower surface of the light guide 14.

  As shown in FIGS. 3 to 5, the first end side end of the arm portion 12 in the light guide 14 is provided with a knob component portion 14 b that constitutes a part of the operation knob 13. It is in an exposed state. Further, the exposed portion of the knob constituting portion 14b is blasted. On the other hand, the light guide 14 is provided with a curved condensing portion 14c that is a part of the light guide 14 and is disposed so as to surround the light emitter 15a at the end of the arm portion 12 on the second end side. Yes. This condensing part 14c is formed wider than the arm part 12, and is comprised by the concave curved surface used as a part of circular arc in planar view. For this reason, the light emitted from the light emitter 15a is efficiently collected by the light collecting portion 14c and guided to the operation knob 13 side by the light guide 14. Since the portion exposed to the operation knob 13 in the light guide 14 is blasted, the guided light is radiated to the outside from the exposed portion. Therefore, when light is emitted from the light source 15, the operation knob 13 emits light.

  In the thermal power control apparatus 11 configured in this way, it can swing from a high fire position as shown by a solid line in FIG. 7 to a low fire position as shown by a two-dot chain line in FIG. Is in the middle fire position. And the thermal power control apparatus 11 comes to have the light source 15 on the extended line of the direction where the arm part 12 and the light guide 14 extend in any position. Therefore, the light emitted from the light source 15 is stably guided to the operation knob 13 regardless of the position of the high power position, the medium heat position, and the low heat position. Therefore, the brightness of the light emitted from the operation knob 13 is constant regardless of the position of the thermal power control device 11. In FIG. 7, the protruding piece 12a provided on the arm portion 12 is omitted.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) The light emitted from the light source 15 is guided to the operation knob 13 by the light guide 14 provided from the first end portion to the second end portion of the arm portion 12, and the operation knob 13 emits light. For this reason, the visibility of the operation knob 13 is improved, and the operability is improved. Moreover, the light source 15 is provided in the vicinity of the second end that is the inner side of the stove body 2. For this reason, dirt caused by spilling, oily dirt, and the like are less likely to adhere to the light source 15, and light from the light source 15 is prevented from being blocked by the dirt. In particular, in the gas stove 1, the throttle valve 24 is disposed at a position separated from the front panel 2 a due to the structure of the on-off valve mechanism 21 in the stove body 2. For this reason, it is necessary to make the arm part 12 long and to set the pivotal attachment part between the arm part 12 and the throttle valve 24 inside the stove body 2. Therefore, by providing the light source 15 at the second end of the arm portion 12, the light source 15 is positioned inside the stove body 2, so that dirt or oil stains due to spillage adhere to the light source 15. It becomes difficult. Further, since the light emitted from the light source 15 is guided inside the light guide 14, even if dirt is attached to the surface of the light guide 14, the light is reliably guided to the operation knob 13. . Therefore, the operation knob 13 can emit light reliably. Therefore, the visibility of the operation knob 13 can be improved, and the operability of the thermal power control device 11 can be improved. Further, since the front panel 2a is decorated with light, the appearance of the front panel 2a is improved. That is, the design of the gas stove 1 is also improved.

  (2) The light source 15 is fixed to the arm portion 12 and swings together with the arm portion 12. For this reason, the brightness of the light emitted from the operation knob 13 is constant no matter how the arm portion 12 is swung. That is, the brightness of the light emitted from the operation knob 13 can be made uniform.

  (3) Since a gap corresponding to a height C is positively provided between the arm portion 12 and the light guide 14, the liquid that causes dirt such as boiled spilled liquid is generated by the arm portion 12 and the light guide 14. It becomes difficult to enter between. Incidentally, when no gap is provided between the arm portion 12 and the light guide 14, if there is a slight gap between the arm portion 12 and the light guide 14, the arm portion 12 and the light guide 14 The liquid enters into the gap due to the surface tension generated between the two. In other words, when no gap is provided between the arm portion 12 and the light guide 14, a liquid that causes dirt may infiltrate into the gap unless a slight gap is formed between the two. It becomes easy. For this reason, it is possible to prevent liquid from infiltrating into the gap by positively providing a predetermined gap between the arm portion 12 and the light guide 14.

  (4) At the end of the light guide 14 on the light source 15 side, a curved condensing part 14c surrounding the light source 15 is provided. For this reason, the light emitted from the light source 15 is reliably condensed by the condensing part 14c. Therefore, the light emitted from the light source 15 can be guided with high efficiency.

  (5) The light source 15 is disposed on an extension line in the direction in which the arm portion 12 and the light guide 14 extend. For this reason, the light emitted from the light source 15 is linearly guided through the light guide 14 and radiated to the outside from the operation knob 13. For this reason, the operation knob 13 can emit light with high luminance.

In addition, you may change embodiment of this invention as follows.
In the embodiment, the light guide 14 is configured to be narrower than the arm portion 12 and is fixed to the upper surface of the arm portion 12. However, for example, as shown in FIG. 8A, the light guide 14 is configured to be wider than the arm portion 12 and is fixed to the arm portion 12 so as to cover the upper surface and both side surfaces of the arm portion 12. It may be. In this way, the connection strength between the arm portion 12 and the light guide 14 can be increased. In addition, since the joint end of the arm portion 12 and the light guide 14 is on the lower surface side of the arm portion 12, the liquid causing the contamination is difficult to enter from the joint end into the gap between them.

  The light guide 14 is configured to be narrower than the arm portion 12 and fixed to the lower surface side of the arm portion 12 as shown in FIG. 8B, for example. Also good. Even in this case, since the joint end of the arm portion 12 and the light guide 14 is on the lower surface side of the arm portion 12, the liquid causing the contamination is less likely to enter the gap between the joint end and the arm portion 12.

  In addition, as shown also in each said figure, the protrusion 14a provided in the light guide 14 in the said embodiment was abbreviate | omitted, and predetermined gap (gap for height C) was provided between the arm part 12 and the light guide 14. ) May not be actively provided.

  In the above-described embodiment, the light source 15 is provided integrally with the arm portion 12 and swings together with the arm portion 12. However, for example, as shown in FIG. 9, the light source 15 does not need to be fixed to the arm portion 12 and may not be swung together with the arm portion 12. Even if it does in this way, as shown in FIG. 10, for example, as shown in FIG. 10, the light emitted from the light source 15 is collected by the light collecting portion 14c regardless of the position of the high fire position, the medium fire position and the low fire position. Since the light is reliably collected, light is emitted from the operation knob 13 with uniform brightness. In FIG. 10, the protruding piece 12a provided on the arm portion 12 is omitted.

  In the embodiment, the light source 15 is provided on an extension line in the direction in which the light guide 14 extends. However, for example, as illustrated in FIGS. 11A and 11B, the light source 15 may be disposed above the light guide 14 in the vicinity of the second end portion of the arm portion 12. Specifically, as shown in each drawing, a condensing portion 14c extending upward is provided at the second end portion side end of the arm portion 12 in the light guide 14. And the concave condensing surface 14d which surrounds the light-emitting body 15a of the light source 15 is provided in the upper end of the condensing part 14c. Even in this case, the light emitted from the light source 15 can be guided to the operation knob 13 by the light guide 14.

  Note that. In these modified examples, the condensing surface 14d is provided on the vertical line V at the swing fulcrum (point P0) of the arm portion 12. In FIG. 11A, the light source 15 is disposed at a position (on the vertical line V) perpendicular to the arm portion 12, and in FIG. It is arranged at a position about 45 ° above. In either case, the tip of the light emitter 15a of the light source 15 is positioned on the vertical line V. For this reason, the light emitted from the light source 15 is reliably collected by the light collecting portion 14c regardless of the position of the operation knob 13 in the high fire position, the medium fire position, or the low fire position. Can emit light with uniform brightness.

  -As the light emitter 15a of the light source 15, for example, a multicolor LED may be used. Then, the emission color may be changed according to the heating power adjustment position. For example, an LED having three color light emission modes is used as the light emitter 15a. When the operation knob 13 is in the high fire position, the light emitter 15a emits red light. When the operation knob 13 is in the medium fire position, the light emitter 15a emits orange light, and the operation knob 13 is in the low fire position. In some cases, the light emitter 15a emits green light. Alternatively, a full-color LED may be used as the light emitter 15a, and light may be emitted in white when in a fire extinguishing state. In this way, the operator can recognize the heating power adjustment position more reliably and easily.

  The gas stove 1 is not limited to a drop-in gas stove, and may be a stationary gas stove. Further, the gas cooker is not limited to the gas stove 1 with a grill as shown in the above-described embodiment, and is specifically, for example, a gas stove that does not have a grill part, a gas grill configured only by the grill part, a gas oven, or the like.
