Description

  The present invention relates to a stove.

  BACKGROUND ART Heretofore, there has been known a stove in which an operation button is arranged on the front side of a fuel supply device having a pressed portion that moves forward and backward. For example, in the stove disclosed in Patent Document 1, the gas supply device 43 including the ignition switch 431 is provided in the housing 2, and the ignition switch 431 is retracted to the front panel 50 provided in the front portion of the housing 2. An ignition button 13 is provided to activate the ignition.

JP, 2018-44709, A

  The ignition button 13 of the stove disclosed in Patent Document 1 is provided with a contact portion 154 that contacts the ignition switch 431 of the gas supply device 43 provided in the housing 2. The contact portion 154 is composed of a plurality of ribs 154A protruding rearward from the back surface of the front wall portion 131 exposed to the outside of the stove. Then, when the ignition button 13 is pushed in, the contact portion 154 contacts the tip of the ignition switch 431, and the ignition switch 431 moves backward in conjunction with the operation of displacing the ignition button 13 rearward. Then, the gas flow path in the gas supply device 43 is opened or cut off, and the stove burner 7 is ignited or extinguished.

  By the way, the ignition button 13 is required to have sufficient strength to withstand the load applied during the pushing operation. However, when the thickness of the rib 154A is increased in order to make the ignition button 13 sufficiently strong, there is a concern that the front surface of the front wall portion 131 may be sinked due to the formation of the rib 154A. If such a sink mark appears on the surface of the ignition button 13 exposed to the outside of the stove, there is a possibility that the aesthetics of the stove may be impaired, which is a problem.

  The present invention has been made to solve at least one of the problems described above, and an object thereof is to provide a stove capable of suppressing the appearance of sink marks on the exposed surface of the operation button.

The stove of one embodiment of the present invention is
A stove in which an operation button is arranged on the front side of a fuel supply device including a pressed portion that moves forward and backward.
The operation buttons are
A first wall portion disposed on the front side of the pressed portion and having a front surface exposed to the outside of the stove;
A second wall portion that is disposed between the first wall portion and the pressed portion on the front side of the pressed portion and that is integrally provided with the first wall portion;
The second wall portion is configured to protrude toward the pressed portion side, and has a protruding portion that pushes the pressed portion rearward in conjunction with an operation of displacing the first wall portion rearward. ,
An air gap exists between the rear surface of the first wall portion and the front surface of the second wall portion.

  In the stove according to the one aspect described above, even if a sink mark due to the formation of the protruding portion appears on the front side portion of the protruding portion when the operation button is formed, there is a concern that the sink mark may appear on the front surface of the second wall portion, but the front side via the gap. Is difficult to appear on the front surface (exposed surface) of the first wall portion arranged at. Therefore, it is possible to more reliably prevent the sink mark caused by the protrusion from appearing on the exposed surface and impairing the appearance of the stove.

FIG. 3 is a perspective view of the front panel to which the ignition button is attached as seen obliquely from the rear side. FIG. 4 is a rear view of the front panel to which the ignition button is attached as seen from the rear side. FIG. 5 is a cross-sectional view schematically showing a cross section of the ignition button taken along the line AA in FIG. FIG. 6A is a cross-sectional view schematically showing a cross section of the ignition button taken along line BB in FIG. FIG. 6 (B) is a cross-sectional view schematically showing a state where the ignition button is pushed in from the state of FIG. 6 (A). FIG. 7A is a sectional view schematically showing an ignition button in the gas stove according to the second embodiment. FIG. 7 (B) is a cross-sectional view schematically showing a state where the ignition button is pushed in from the state of FIG. 7 (A).

Here, a desirable example of the present invention will be shown.
The stove includes a third wall portion that is connected to the second wall portion and extends from the front surface of the second wall portion toward the first wall portion, and includes a rear surface of the first wall portion and a front surface of the second wall portion. Voids may exist in the region other than the third wall portion. According to this structure, the vicinity of the front surface of the second wall portion can be reinforced by the third wall portion. Regarding the concern that sink marks may be generated due to the formation of the third wall portion when the operation button is formed, a gap may be formed in a region other than the third wall portion between the rear surface of the first wall portion and the front surface of the second wall portion. Since this is ensured, the effect of sink marks is less likely to occur at least at the front surface (exposed surface) of the first wall portion at the front position of the void. Therefore, it is possible to both improve the strength in the vicinity of the second wall portion and suppress the deterioration of the aesthetic appearance due to sink marks.

  The front end of the third wall portion may be separated from the rear surface of the first wall portion. In this way, if the front end of the third wall portion is separated from the rear surface of the first wall portion, a sink mark due to the formation of the third wall portion on the front surface (exposed surface) of the first wall portion when the operation button is formed. The appearance can be suppressed more reliably.

  The protrusion may have a rib shape, and the thickness of the third wall may be smaller than the thickness of the protrusion. In this way, if the thickness of the third wall portion is smaller than the thickness of the projecting portion, the sink mark caused by the formation of the third wall portion can be reduced while realizing the reinforcing structure by the third wall portion. Or it may not occur.

Further, the fuel supply device 80 is configured such that the gas flow path is opened at the rear position of the pressed portion 83 and the gas flow path is blocked at the front position of the pressed portion 83.

  In the "stove", the position of the fuel supply device in the housing may be preset, and in such a case, the arrangement and shape of the ignition button may be restricted depending on the position of the pressed portion. The ignition button is a component that forms the outer appearance of the stove and is easily noticed by the user in terms of the function as an operating unit, and it can be said that the arrangement and shape thereof are problems from the viewpoint of maintaining the aesthetics of the stove. In particular, as shown in FIG. 1, the gas stove 1 according to the first embodiment has a line-shaped design extending in the left-right direction over the entire length of the front surface by the ignition buttons 11-14, the handle 8C of the grill door 8B, and the like. From the viewpoint of maintaining the aesthetic appearance of the gas stove 1, the arrangement and shape of the ignition button 11 are particularly problematic. In view of such circumstances, the ignition button 11 of the first embodiment has the following configuration.

  As shown in FIGS. 3 and 4, the ignition button 11 is a resin molded product in which each part is integrally injection molded. The ignition button 11 has a main body 30 that is exposed from the opening 21 of the front panel 20 to the front surface side, and an attachment portion 60 that extends upward from the main body 30 and is attached to the front panel 20.

The ignition button 11 is configured to swing back and forth around the swing shaft 61 with respect to the front panel 20 when the main body portion 30 is pushed in, and when the swing button 11 swings, the shaft center 61A (central axis) is set. It swings (rotates) around the center.

  As shown in FIGS. 4 and 5, the main body portion 30 has a rectangular shape in front view, which is slightly smaller than the opening 21 of the front panel 20, and has a substantially box shape that is opened rearward as a whole. The main body portion 30 has a front wall portion 32 extending vertically along the upper side of the main body portion 30, a lower wall portion 34 extending vertically along the lower portion of the main body portion 30, and a front wall portion 32. The projecting wall portion 33 has a structure projecting forward from the lower end of the lower wall portion 34 and the upper end of the lower wall portion 34, and a peripheral wall portion 35 that rises rearward from the periphery of these wall portions 32, 33, 34. .

  The front wall portion 32 is disposed on the front side of the pressed portion 83 and has a front surface 32A exposed to the outside of the gas stove 1. The front wall portion 32 is an example of a first wall portion. The front wall portion 32 has the front surface 20 </ b> A flush with the front surface of the decorative panel 70 when the decorative panel 70 is mounted on the front panel 20. The overhang wall portion 33 is a portion that the user applies by pushing with a finger or the like when pushing the ignition button 11. Further, the overhanging wall portion 33 has the same overhanging dimension as the handle 8C of the grill door 8B and the panel side overhanging portion 71 provided on the decorative panel 70, and the upper surface of the handle 8C and the panel side overhanging portion 71. It is located in the same plane as the upper surface and constitutes a series of designs with these.

  The ignition button 11 further includes a rear wall portion 40 that is disposed behind the front wall portion 32 so as to face the front wall portion 32. The rear wall portion 40 is disposed between the front wall portion 32 and the pressed portion 83 on the front side of the pressed portion 83, and is provided integrally with the front wall portion 32. The rear wall portion 40 is an example of the second wall portion. Specifically, the rear wall portion 40 has a wall shape having substantially the same shape as the front wall portion 32, and is arranged parallel to the front wall portion 32. The rear wall portion 40 has an upper end connected to the upper end of the front wall portion 32 via the upper portion of the peripheral wall portion 35, and a lower end connected to the lower end of the front wall portion 32 via the connection wall portion 36. The upper portion of the peripheral wall portion 35 is a portion that is inserted into the opening 21 of the front panel 20, and the upper surface is covered with the front panel 20 or the decorative panel 70 and exposed to the outside when the ignition button 11 is not pushed in and operated. It is supposed not to. The connection wall portion 36 has a wall shape extending from the vicinity of the position where the protruding wall portion 33 projects forward at the lower end of the front wall portion 32 to the side opposite to the protruding wall portion 33. In addition, the left end and the right end of the rear wall portion 40 are not connected to the front wall portion 32, and a molding die for forming a void 45 described later can be pulled out to the left and right (see FIG. 6). .

  The rear wall portion 40 has a protruding portion 41 configured to protrude toward the pressed portion 83 side. Further, the front wall 40 </ b> A of the rear wall portion 40 is provided with a reinforcing wall portion 50 for reinforcing the ignition button 11. The reinforcing wall portion 50 is connected to the rear wall portion 40 and extends from the front surface 40A of the rear wall portion 40 toward the front wall portion 32 side. The reinforcing wall portion 50 is an example of the third wall portion.

  The protruding portion 41 protrudes rearward from a position facing the pressed portion 83 on the back surface 40B of the rear wall portion 40. The protruding portion 41 has a rib shape extending in the up-down direction on the back surface 40B of the rear wall portion 40, and is formed by arranging three ribs on the left and right of the rear wall portion 40. The projecting portion 41 constitutes a contact surface 41 </ b> A with which the projecting end surface of each rib contacts the pressed portion 83. The protruding portion 41 pushes the pressed portion 83 rearward in conjunction with the movement of the front wall portion 32 rearward (see FIG. 6). In the ignition button 11, the protruding portion 41 is formed in a rib shape, so that the protruding height of the protruding portion 41 is appropriately changed according to the position of the pressed portion 83, and the position of the contact surface 41A can be easily designed. It is said that In the first embodiment, the protrusion 41 has a higher protrusion height as it goes upward, and the upper end is connected to the peripheral wall portion 35.

  The reinforcing wall portion 50 has a wall shape that extends in the up-down direction so as to partition at least a part of the void 45 into the left and right, and is connected to the front side of the protruding portion 41 in the rear wall portion 40. The reinforcing wall portion 50 has an upper end connected to the upper portion of the peripheral wall portion 35 and a lower end connected to the connection wall portion 36, while the front end 50A is not connected to the front wall portion 32. When the ignition button 11 is pushed in, the upper portion of the peripheral wall portion 35 has an inclined posture in which the upper surface descends forward, and the front portion of the upper surface may be visually recognized from the opening 21 of the front panel 20. In the first embodiment, the reinforcing wall portion 50 is not connected to the front side portion (the portion near the front wall portion 32) of the peripheral wall portion 35, and the peripheral wall portion 35 has a sink mark due to the formation of the reinforcing wall portion 50. Even if it appears, such a sink mark is hard to be visually recognized from the outside. That is, in the first embodiment, the rear wall portion 40 is structurally reinforced by the reinforcing wall portion 50 connected to a portion that does not have an exposed surface exposed to the outside of the gas stove 1, and the strength of the ignition button 11 is increased. .

  The ignition button 11 has a gap 45 between the rear surface 32B of the front wall portion 32 and the front surface 40A of the rear wall portion 40. The void 45 exists at least in the regions 45A and 45B other than the reinforcing wall portion 50 between the rear surface 32B of the front wall portion 32 and the front surface 40A of the rear wall portion 40. In the first embodiment, the void 45 also exists in the region 45C between the rear surface 32B of the front wall portion 32 and the reinforcing wall portion 50. Specifically, the void 45 is the reinforcing wall portion 50 in the space surrounded by the front wall portion 32, the rear wall portion 40, the upper portion of the peripheral wall portion 35, and the connection wall portion 36 in a rectangular tube shape. Areas 45A, 45B, and 45C other than the area occupied by. Such a void 45 has, for example, an undercut shape when the ignition button 11 is injection-molded by a pair of molds whose front-rear direction is the mold opening direction. From the viewpoint of moldability, the ignition button is generally a simple box shape or the like that does not have an undercut shape, but in the first embodiment, the front wall portion 32 is formed by forming the void 45. Is separated from the portion of the rear wall portion 40 where the protrusion 41 is joined. Then, the front wall portion 32 is formed in a flat plate shape having a predetermined thickness so that a local molding defect such as a sink is unlikely to occur on the front surface 32A of the front wall portion 32 exposed to the outside of the gas stove 1. There is.

Subsequently, an ignition operation and a fire extinguishing operation of the gas burner 4 by the ignition button 11 of the first embodiment will be described with reference to FIG.
When the user presses the overhanging wall portion 33 and pushes the ignition button 11 when the gas burner 4 is in the fire extinguishing state, the ignition button 11 rotates rearward around the swing shaft 61. Then, the contact surface 41A of the protruding portion 41 contacts the pressed portion 83 of the fuel supply device 80, and the pressed portion 83 at the front position shown in FIG. The pushed portion 83 that has moved backward is held at the rear position shown in FIG. 6B by the push-push mechanism, and the gas flow path of the fuel supply device 80 is opened. Then, the gas is supplied from the fuel supply device 80 to the gas burner 4 and ignited by the igniter.

  In a state where the gas burner 4 is ignited, when the user puts a finger on the overhanging wall portion 33 or the like and pushes the ignition button 11, the ignition button 11 rotates backward around the swing shaft 61. Then, the contact surface 41A of the protruding portion 41 contacts the pressed portion 83 of the fuel supply device 80, and the pressed portion 83 at the rear position shown in FIG. 6B is further advanced rearward. The pressed portion 83 that has advanced to the rear is released from being held at the rear position by the push-push mechanism, and is displaced to the front position shown in FIG. 6A by the forward biasing force to move to the gas flow path of the fuel supply device 80. Is cut off. Then, the gas is not supplied from the fuel supply device 80 to the gas burner 4, and the gas burner 4 is extinguished.

Next, the effect of this configuration will be illustrated.
In the gas stove 1 described above, even if a sink mark due to the formation of the protrusion 41 at the time of forming the ignition button 11 appears at a portion on the front side of the protrusion 41, there is a concern that it may appear at the front surface 40A of the rear wall portion 40. The front wall portion 32 disposed on the front side through the front surface 32A (exposed surface) is less likely to appear. Therefore, it is possible to more reliably prevent the sink mark resulting from the protruding portion 41 from appearing on the exposed surface and impairing the aesthetic appearance of the gas stove 1.

  The occurrence of sink marks on the exposed surface of the ignition button 11 contributes to a decrease in the yield of the ignition button 11. In the gas stove 1 described above, since the sink mark caused by the protrusion 41 is less likely to appear on the exposed surface, the reduction in the yield of the ignition button 11 can be suppressed.

The ignition button 11 includes a reinforcing wall portion 50, and a gap 45 exists between the rear surface 32B of the front wall portion 32 and the front surface 40A of the rear wall portion 40 in regions 45A and 45B other than the reinforcing wall portion 50. With such a configuration, the vicinity of the front surface 40A of the rear wall portion 40 can be reinforced by the reinforcing wall portion 50. Specifically, when the ignition button 11 is pushed in, a load is applied to the protruding portion 41 that comes into contact with the pressed portion 83, but the strength of the rear wall portion 40 can be ensured by the reinforcing wall portion 50, and the protruding portion 41 can be secured. Even when an excessive load is applied to 41, it is possible to prevent the ignition button 11 from being damaged.
Regarding the concern that sink marks may be generated due to the formation of the reinforcing wall portion 50 at the time of forming the ignition button 11, an area other than the reinforcing wall portion 50 between the rear surface 32B of the front wall portion 32 and the front surface 40A of the rear wall portion 40. Since the void 45 is secured in the spaces 45A and 45B, the influence of the sink mark is less likely to occur at least in the front position of the void 45 on the front surface 32A (exposed surface) of the front wall portion 32. Therefore, it is possible to both improve the strength in the vicinity of the rear wall portion 40 and suppress the deterioration of the aesthetic appearance due to sink marks.

  The front end 50A of the reinforcing wall portion 50 is separated from the rear surface 32B of the front wall portion 32. As described above, when the front end 50A of the reinforcing wall portion 50 is separated from the rear surface 32B of the front wall portion 32, the sink mark due to the formation of the reinforcing wall portion 50 at the time of forming the ignition button 11 causes the front surface 32A of the front wall portion 32 ( The appearance on the exposed surface can be more reliably suppressed.

<Example 2>
Next, a gas stove according to the second embodiment will be described with reference to FIG. 7 and the like. In the gas stove shown in the second embodiment, the ignition button 211 is the same as the gas stove 1 in the first embodiment except that the structure of the reinforcing wall portion 250 is different from the ignition button 11 in the first embodiment. Therefore, in the gas stove of the second embodiment shown in FIG. 7, the same parts as those of the gas stove 1 of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

  The reinforcing wall portion 250 is connected to the rear wall portion 40 and extends from the front surface 40A of the rear wall portion 40 toward the front wall portion 32 side. The reinforcing wall portion 250 is an example of the third wall portion. The thickness of the reinforcing wall portion 250 is smaller than the thickness of the protruding portion 41. More specifically, the reinforcing wall portion 250 is thinner than each rib forming the protruding portion 41, and the sink mark caused by the formation of the reinforcing wall portion 250 is smaller than the sink mark caused by the formation of the protruding portion 41 (the sink mark). (Including the case that does not occur) is designed to a thickness dimension that can be. The reinforcing wall portion 250 has a wall shape that divides the void 45 into right and left, and is connected to the front side of the protruding portion 41 of the rear wall portion 40. The reinforcing wall portion 250 is configured such that the upper end is connected to the upper portion of the peripheral wall portion 35, the lower end is connected to the connecting wall portion 36, and the front end is connected to the rear surface 32B of the front wall portion 32. In the second embodiment, both the front wall portion 32 and the rear wall portion 40 are structurally reinforced by the reinforcing wall portion 250, so that the strength of the ignition button 211 can be secured.

  The ignition button 211 has a gap 245 between the rear surface 32B of the front wall portion 32 and the front surface 40A of the rear wall portion 40. The void 245 exists between the rear surface 32B of the front wall portion 32 and the front surface 40A of the rear wall portion 40 in the regions 45A and 45B other than the reinforcing wall portion 50. Specifically, the void 245 is the reinforcing wall portion 250 in the space surrounded by the front wall portion 32, the rear wall portion 40, the upper portion of the peripheral wall portion 35, and the connection wall portion 36 in a rectangular tube shape. Areas 45A and 45B other than the area occupied by Such a gap 245 has an undercut shape, for example, when the ignition button 11 is injection-molded by a pair of molds whose mold opening direction is the front-rear direction. From the viewpoint of moldability, the ignition button is generally a simple box shape or the like that does not have an undercut shape, but in the second embodiment, by forming the void 245, the front wall portion 32 is formed. Is separated from the portion of the rear wall portion 40 where the protrusion 41 is joined. Then, the front wall portion 32 is formed into a flat plate shape having a predetermined thickness except for the portion where the reinforcing wall portion 250 is connected to the rear surface 32B, and the front surface 32A of the front wall portion 32 exposed to the outside of the gas stove 1 is sunk. A structure in which local defective molding such as is unlikely to occur is realized.

  In this way, when the thickness of the reinforcing wall portion 250 is smaller than the thickness of the protruding portion 41, the sink mark caused by the formation of the reinforcing wall portion 250 can be reduced while realizing the reinforcing structure by the reinforcing wall portion 250. It may or may not occur.

  In the embodiment described above, the configuration in which the front wall portion 32 corresponds to the first wall portion is illustrated, but the configuration of the first wall portion is not limited to this. Depending on the position of the pressed portion 83, the first wall portion may be configured by the lower wall portion 34, the overhanging wall portion 33, or the like, and the first wall may extend over the front wall portion 32 and the overhanging wall portion 33. Parts may be configured.

  In the above-described embodiment, the configuration in which the rear wall portion 40 corresponds to the second wall portion is illustrated, but the configuration of the second wall portion is not limited to this. In the above-described embodiment, the rear wall portion 40 is connected to the front wall portion 32 via the peripheral wall portion 35 and the connection wall portion 36, but the second wall portion is integrated with the first wall portion. However, the configuration that is provided specifically is not limited to this. The rear wall portion 40 may have a configuration in which a side end portion is connected to the front wall portion 32, for example, and is connected to the front wall portion 32 via a portion other than the peripheral wall portion 35 and the connection wall portion 36. The configuration may be different.

  In the above-described embodiments, the configuration in which the protruding portion 41 has a rib shape extending in the vertical direction is illustrated, but the configuration is not limited to this. The protrusion may have a protrusion shape, or may have a lattice rib shape.

  In the above-described embodiment, the structure in which the voids 45 and 245 are present in the area other than the reinforcing wall portions 50 and 250 between the rear surface 32B of the front wall portion 32 and the front surface 40A of the rear wall portion 40 is illustrated, but the present invention is not limited to this. I can't. For example, when the strength of the rear wall portion is ensured, the reinforcing wall portion may not be provided, and the void may exist in the entire area between the rear surface 32B of the front wall portion 32 and the front surface 40A of the rear wall portion 40. Good.

  In addition to the above-described embodiments, the shape of the reinforcing wall portion, the thickness dimension, the connecting position to the rear wall portion 40, and the like can be appropriately designed. For example, in the above-described embodiment, the reinforcing wall portions 50 and 250 have a wall shape that divides the void into left and right, but the reinforcing wall portion may have a wall shape that divides the void into upper and lower portions.

  Although the gas stove 1 of the above-described embodiment is a built-in stove, it may be a table stove or the like.
