[0008] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0009] (1) A gas stove according to the present disclosure is a gas stove comprising: a gas burner; a housing that houses the gas burner; an ignition switch that is provided inside the housing and that ignites and extinguishes the gas burner; a front panel attached to the front of the housing; a swing-type ignition button that is disposed in front of the ignition switch and that is pressed to operate the ignition switch; and a decorative panel attached to the front of the front panel, wherein the ignition button comprises a pressing portion disposed at a front end and a swing shaft that is disposed at a rear end and that protrudes in the left-right direction, and the front panel comprises a front plate, an insertion hole formed in the front plate and through which the ignition button is inserted, a plurality of support plates extending rearward from left and right hole edges of the insertion hole, bearing holes formed in each of the plurality of support plates and that receive the swing shaft, and a slit that extends rearward from the bearing hole and opens rearward, and the decorative panel is configured to be mounted on the front panel with the pressing portion exposed forward. The device has an operation window through which an ignition button is inserted, and the swing axis has a generally oval shape that is long in a first direction when viewed from the side. When the extension direction of the slit coincides with the first direction, the swing axis is allowed to pass through the slit, and when the extension direction of the slit intersects with the first direction, the swing axis is restricted from passing through the slit. When the decorative panel is not attached to the front panel, the ignition button can swing downward by a first angle from an upper restriction position where upward swing is restricted, and can reach a first position. When the ignition button is in the first position, the extension direction of the slit coincides with the first direction. When the decorative panel is attached to the front panel, the ignition button swings downward by a second angle smaller than the first angle from the upper restriction position, and interferes with the lower edge of the operation window, making it impossible to reach the first position.

[0010] With this configuration, the ignition button cannot reach the first position due to interference with the decorative panel, so the oscillating shaft can be prevented from coming out of the bearing hole and the ignition button falling out rearward without the need for any additional parts.

[0011] (2) In (1) above, the ignition button preferably has an interference portion that interferes with the lower edge of the operation window and a protective portion that fills the gap between the interference portion and the lower edge of the operation window when the ignition button is in the upper restricted position, and the protective portion preferably has an outer surface that is approximately arc-shaped with the swing axis as the center when viewed from the side.

[0012] According to this configuration, the provision of the protective portion prevents the interior of the gas stove from being seen through the gap between the interference portion and the lower edge of the operation window. Furthermore, since the protective portion has an outer surface that is approximately arc-shaped when viewed from the side, interference between the protective portion and the operation window can be avoided when operating the ignition button. Furthermore, the above configuration enhances the design of the ignition button.

[0013] [Details of the embodiments of the present disclosure] Embodiments of the present disclosure will be described with reference to Figures 1 to 15. The present disclosure is not limited to these examples, but is defined by the scope of the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0014] [Overall configuration of gas stove] The gas stove 1 of this embodiment is a built-in stove that is incorporated into a kitchen cabinet. As shown in Figures 1 and 2, the gas stove 1 includes a housing 2. The housing 2 is substantially rectangular parallelepiped-shaped. A grill section 6 is provided near the center of the housing 2. The grill section 6 includes a box-shaped grill compartment and a grill door 6A that opens and closes the grill compartment.

[0015] As shown in Fig. 1, multiple gas burners are housed in the housing 2. Specifically, the multiple gas burners are a right burner 3 disposed on the front right, a left burner 4 disposed on the front left, a rear burner 5 disposed on the rear center side, and a grill burner (not shown) disposed inside the grill chamber.

[0016] 1 and 2, a right panel unit 7 and a left panel unit 8 are provided at the front of the housing 2. The right panel unit 7 is disposed on the right side of the grill 6. The left panel unit 8 is disposed on the left side of the grill 6.

[0017] Ignition buttons 11 and 12 are provided side by side on the right panel unit 7, starting from the right. Pressing ignition button 11 turns on and off the right burner 3. Pressing ignition button 12 turns on and off the grill burner. Operating levers 15A and 15B are located above the ignition buttons 11 and 12 on the right panel unit 7, respectively. Moving operating lever 15A left and right adjusts the heat output of the right burner 3. Moving operating lever 15B left and right adjusts the heat output of the grill burner.

[0018] An operation unit 7A is provided below the ignition buttons 11, 12 of the right panel unit 7 so that it can be pulled out forward. When the operation unit 7A is pulled out, an operation panel 24A (see FIG. 2) provided on the operation unit 7A is located in an operable position. By operating the operation panel 24A, it is possible to set, for example, the heating temperature and heating time for cooking with each gas burner (right burner 3, grill burner).

[0019] Ignition buttons 13 and 14 are provided side by side on the left panel unit 8, starting from the right. By pressing ignition button 13, the rear burner 5 can be ignited and extinguished. By pressing ignition button 14, the left burner 4 can be ignited and extinguished. Operation levers 15C and 15D are located above the ignition buttons 13 and 14 on the left panel unit 8, respectively. By moving operation lever 15C left and right, the flame power of the rear burner 5 can be adjusted. By moving operation lever 15D left and right, the flame power of the left burner 4 can be adjusted.

[0020] An operation unit 8A is provided below the ignition buttons 13, 14 of the left panel unit 8 so as to be able to be pulled out forward. The operation unit 8A is configured in substantially the same manner as the operation unit 7A of the right panel unit 7.

[0021] The configuration of the right panel unit 7 will be described in detail below. The configuration of the left panel unit 8 is substantially the same as the configuration of the right panel unit 7, so a detailed description will be omitted. As shown in Fig. 2, the right panel unit 7 includes a front member 20 fixed to the front part of the housing part 2, a decorative panel 40 attached to the front side of the upper part of the front member 20, and a covering member 47 attached to the front side of the lower part of the front member 20.

[0022] As shown in Fig. 3, the front member 20 includes a frame body 21, a button unit 26 fitted into an upper opening 21A of the frame body 21, and an operation unit main body 22 fitted into a lower opening 21B of the frame body 21. As shown in Fig. 2, a decorative panel 40 is attached to the front panel 30 of the button unit 26. A covering member 47 is attached to the operation unit main body 22.

[0023] As shown in FIG. 3 , the operation unit main body 22 includes a frame 23, a rotating body 24, and a battery box 25. The frame 23 includes a rotating body housing 23B having a rectangular opening 23A, a shaft 23C provided at the lower edge of the opening 23A, and a battery box housing 23D provided inside the opening 23A. The shaft 23C extends in the left-right direction. The rotating body 24 is generally fan-shaped in a side view. The rotating body 24 includes an operation panel 24A and a bearing 24B that engages with the shaft 23C. The bearing 24B engages with the shaft 23C, allowing the rotating body 24 to rotate around the shaft 23C. The rotating body 24 is rotatable between an operation position where the operation panel 24A is exposed forward and a housing position where the rotating body 24 is housed within the rotating body housing 23B. The rotating body 24 also has a battery box housing portion 23D and an escape recess 24C for the battery box 25. The battery box housing portion 23D is box-shaped and opens to the front. The battery box 25 can be inserted into the battery box housing portion 23D from the front. The battery box 25 houses dry batteries for supplying power to the gas stove 1.

[0024] [Front Panel] The button unit 26 includes a front panel 30 and two ignition buttons 11 and 12 arranged side by side in the left-right direction on the front panel 30. As shown in FIGS. 4, 5, and 7, the front panel 30 has a front plate 31 and two insertion holes 32 and 33 formed in the front plate 31. The two ignition buttons 11 and 12 are respectively inserted into the two insertion holes 32 and 33. As shown in FIG. 4, an intermediate member 31A protruding forward from the front plate 31 is provided between the two insertion holes 32 and 33. The intermediate member 31A is arranged to fill the space between the two ignition buttons 11 and 12 inserted into the two insertion holes 32 and 33, respectively.

[0025] As shown in FIG. 7, two support plates 32A and 32B are provided on the left and right edges of the insertion hole 32. Two support plates 33A and 33B are provided on the left and right edges of the insertion hole 33. The support plates 32A, 32B, 33A, and 33B extend rearward from the front plate 31. Each of the four support plates 32A, 32B, 33A, and 33B has a bearing hole 34 and a slit 35 that extends rearward from the bearing hole 34 and opens rearward. The bearing hole 34 is a hole for supporting the pivot shafts 11A and 12A of the ignition buttons 11 and 12. The slit 35 serves as an entrance for receiving the pivot shafts 11A and 12A into the bearing hole 34. As shown in FIG. 6, the bearing hole 34 has a circular shape in a side view. The slit 35 extends rearward from the vertical center of the bearing hole 34.

[0026] [Ignition button] The ignition buttons 11 and 12 are configured in approximately the same manner. As shown in FIG. 8, swing shafts 11A and 12A are formed at the rear ends of the ignition buttons 11 and 12, protruding in the left-right direction. As shown in FIG. 6, the swing shafts 11A and 12A have a generally oval shape that is long in the first direction D1 in a side view. Specifically, the swing shafts 11A and 12A have two curved surfaces S1 that come into sliding contact with the inner surface of the bearing hole 34 and two connecting surfaces S2 that connect the two curved surfaces S1. The curved surfaces S1 are part of the outer circumferential surface of a cylinder having approximately the same diameter as the bearing hole 34. The two curved surfaces S1 are arranged at both ends of the swing shafts 11A and 12A in the first direction D1. The connecting surfaces S2 are surfaces that are generally parallel to the first direction D1.

[0027] The dimensions of the oscillation shafts 11A, 12A in a direction perpendicular to the first direction D1 (direction perpendicular to the connection surface S2) are set to be equal to or slightly smaller than the dimension in the width direction (vertical direction) of the slit 35. Therefore, as shown in FIGS. 12 and 13 , when the first direction D1 of the oscillation shafts 11A, 12A coincides with the extension direction of the slit 35 (front-rear direction), the oscillation shafts 11A, 12A can pass through the slit 35. Note that "coincidence" here does not only mean a strict coincidence, but also includes a case where the first direction D1 and the extension direction of the slit 35 are roughly coincident within a range where the functions and effects of this embodiment are achieved. Specifically, a case where the first direction D1 and the extension direction of the slit 35 coincide may also include a case where the first direction D1 and the extension direction of the slit 35 are misaligned by several degrees. On the other hand, when the first direction D1 does not coincide with the extension direction of the slit 35, i.e., when the first direction D1 intersects with the extension direction of the slit 35 (for example, as shown in Figures 6, 11, and 15), the oscillation axes 11A and 12A cannot pass through the slit 35.

[0028] As shown in FIG. 8, pressing portions 11B, 12B that protrude forward are provided on the front portions of ignition buttons 11, 12. Interference portions 11D, 12D are provided on the lower portions of pressing portions 11B, 12B. Restriction portions 11E, 12E are provided on the lower ends of ignition buttons 11, 12. Restriction portions 11E, 12E are plate-shaped. Protective portions 11F, 12F are provided between interference portions 11D, 12D and restrictive portions 11E, 12E. As shown in FIG. 11, protective portions 11F, 12F have a substantially arc-shaped outer surface centered on swing shafts 11A, 12A in a side view.

[0029] As shown in FIG. 7, rearward-protruding contact portions 11C and 12C are provided on the back sides of ignition buttons 11 and 12. Contact portions 11C and 12C are adapted to contact the tips of ignition switches 16A and 16B shown in FIG. 2. A fuel supply device including ignition switches 16A and 16B is provided inside housing 2. Ignition switches 16A and 16B are disposed behind ignition buttons 11 and 12. Ignition switches 16A and 16B are biased forward and configured to move forward and backward by a push-push mechanism. When a user presses pressing portions 11B and 12B of ignition buttons 11 and 12, ignition switches 16A and 16B are pressed via contact portions 11C and 12C. When ignition switches 16A and 16B are retracted, the gas flow path of the fuel supply device is opened, and the gas burners (right burner 3 and grill burner) are ignited.

[0030] As shown in Figures 4, 5, and 7, the front panel 30 has two elongated holes 36, 37 arranged side by side in the left-right direction above the two ignition buttons 11, 12. The elongated holes 36, 37 are formed long in the left-right direction. As shown in Figure 2, two operating levers 15A, 15B are inserted into the two elongated holes 36, 37, respectively. The operating levers 15A, 15B are pivotally supported by the fuel supply device and can swing left and right. The user can adjust the amount of gas flowing through the gas flow path by sliding the operating levers 15A, 15B left and right.

[0031] [Decorative panel] As shown in Fig. 10, the decorative panel 40 is formed by press-molding a metal plate. The decorative panel 40 is adapted to be attached to the front panel 30 from the front. The decorative panel 40 includes a front plate portion 41, a first plate portion 42 extending rearward from the upper edge of the front plate portion 41, a second plate portion 43 extending rearward from the lower edge of the front plate portion 41, a third plate portion 44 extending rearward from the right edge of the front plate portion 41, and a fourth plate portion 45 extending rearward from the left edge of the front plate portion 41.

[0032] [Operation window] The decorative panel 40 has an operation window 41A and a slit 41B that penetrate the front plate portion 41 in the front-rear direction. The operation window 41A has a rectangular shape that is long in the left-right direction. The slit 41B is disposed above the operation window 41A and is formed to be long in the left-right direction. As shown in FIG. 2, the two ignition buttons 11, 12 disposed on the front panel 30 are inserted into the operation window 41A. The slit 41B is disposed in front of the two elongated holes 36, 37. The two operation levers 15A, 15B that are inserted into the two elongated holes 36, 37, respectively, are inserted into the slit 41B.

[0033] As shown in Figure 10, a locking member 46 is attached to the first plate portion 42 so as to be slidable in the left-right direction. The locking member 46 is made of, for example, synthetic resin. The locking member 46 has two locking portions 46A that protrude downward from the first plate portion 42. As shown in Figure 4, a lock receiving portion 38 that can be engaged with the two locking portions 46A is provided at the upper end of the front panel 30. The lock receiving portion 38 has a locking wall portion 38A and two receiving recesses 38B that are provided by cutting out the locking wall portion 38A.

[0034] As shown in Fig. 10, two fixing holes 43A are provided at both left and right ends of the second plate portion 43. As shown in Fig. 4, the front panel 30 has two fixing protrusions 39 arranged at positions corresponding to the two fixing holes 43A.

[0035] When the decorative panel 40 is attached to the front panel 30, the ignition buttons 11 and 12 are already attached to the front panel 30 (see FIG. 2). The decorative panel 40 is attached to the front panel 30 from the front. The pressing portions 11B and 12B of the ignition buttons 11 and 12 and the intermediate member 31A of the front panel 30 are inserted into the operation window 41A. Then, the fixing protrusion 39 is inserted into the fixing hole 43A, and the locking portion 46A is received into the lock receiving portion 38 via the receiving recess 38B. Next, by shifting the locking member 46 to the right relative to the first plate portion 42, the locking portion 46A is positioned opposite the locking wall portion 38A in the front-rear direction. This completes the attachment of the decorative panel 40 to the front panel 30.

[0036] [Installing the ignition button on the front panel] As shown in FIG. 13, the ignition buttons 11 and 12 are attached to the front panel 30 from the rear. The decorative panel 40 is not attached to the front panel 30. The pivot shafts 11A and 12A are inserted into the slit 35 with the pressing portions 11B and 12B tilted downward so that the first direction D1 coincides with the extension direction of the slit 35. At this time, the inner wall of the slit 35 and the connection surface S2 come into sliding contact. When the pivot shafts 11A and 12A pass through the slit 35, the front curved surfaces S1 of the pivot shafts 11A and 12A come into contact with the inner wall of the bearing hole 34, as shown in FIG. 12. As a result, the pivot shafts 11A and 12A are disposed inside the bearing hole 34, and the ignition buttons 11 and 12 can pivot relative to the front panel 30. The ignition buttons 11 and 12 are inserted into the insertion holes 32 and 33, and the pressing portions 11B and 12B are in a state of protruding forward.

[0037] [Upper regulation position] When the ignition buttons 11, 12 are not operated with the swing shafts 11A, 12A disposed in the bearing holes 34, the restricting portions 11E, 12E are in rearward contact with the lower edge of the insertion holes 32, 33, as shown in Figure 11. In this state, the ignition buttons 11, 12 are restricted from swinging upward. More specifically, in Figure 11, the ignition buttons 11, 12 are restricted from swinging clockwise. The position of the ignition buttons 11, 12 at this time is defined as the upper restricted position.

[0038] [1st angle, 1st position] As shown in Figure 12, when the decorative panel 40 is not attached to the front panel 30, the ignition buttons 11, 12 can swing downward (counterclockwise in Figure 12) from the upper restricted position by a first angle α to reach the first position. When the ignition buttons 11, 12 are in the first position, the first direction D1 coincides with the extension direction of the slit 35. Therefore, the ignition buttons 11, 12 can be attached to and detached from the front panel 30 (see Figure 13).

[0039] As shown in Figures 9 and 14, when the decorative panel 40 is attached to the front panel 30, the protective portions 11F and 12F are arranged within the operation window 41A when the ignition buttons 11 and 12 are in the upper restricted position and while the ignition buttons 11 and 12 are operated to swing from the upper restricted position to the interference position described below. This allows the protective portions 11F and 12F to block the gap between the interference portions 11F and 12D and the lower edge of the operation window 41A, preventing the interior of the gas stove 1 from being seen from the outside. Furthermore, because the protective portions 11F and 12F have a substantially arc-shaped outer surface, they can be prevented from interfering with the edge of the operation window 41A when the ignition buttons 11 and 12 are operated. Furthermore, the provision of the protective portions 11F and 12F not only conceals the interior of the gas stove 1, but also improves the design of the area formed by the ignition buttons 11 and 12 and the operation window 41A.

[0040] Second Angle As shown in FIG. 15, when the decorative panel 40 is attached to the front panel 30, the ignition buttons 11 and 12 pivot downward (counterclockwise in FIG. 15) from the upper restriction position by a second angle β smaller than the first angle α, causing the interference portions 11D and 12D to interfere with the lower edge of the operation window 41A. The positions of the ignition buttons 11 and 12 at this time are defined as the interference position. The interference between the interference portions 11D and 12D and the lower edge of the operation window 41A prevents the ignition buttons 11 and 12 from pivoting downward beyond the interference position. Therefore, the ignition buttons 11 and 12 cannot reach the first position (see FIG. 12). In other words, the first direction D1 intersects with the extension direction of the slit 35. Therefore, the pivot shafts 11A and 12A cannot enter the slit 35 from the bearing hole 34. Therefore, when the decorative panel 40 is attached to the front panel 30, the swing shafts 11A, 12A are disengaged from the bearing holes 34, and the ignition buttons 11, 12 are prevented from slipping out of the front panel 30 rearward.

[0041] [Effects of the embodiment] As described above, the gas stove 1 of the embodiment is a gas stove 1 including gas burners (right burner 3, grill burner), a housing 2 that houses the gas burners, ignition switches 16A, 16B that are provided inside the housing 2 and that turn on and off the gas burners, a front panel 30 attached to the front of the housing 2, swing-type ignition buttons 11, 12 that are provided in front of the ignition switches 16A, 16B and that are pressed to operate the ignition switches 16A, 16B, and a decorative panel 40 attached to the front of the front panel 30, and the ignition buttons 11, 12 are provided in front of the ignition switches 16A, 16B and are pressed to operate the ignition switches 16A, 16B. The ignition buttons 11 and 12 are provided with pressing portions 11B and 12B arranged at the front end and swinging shafts 11A and 12A arranged at the rear end and projecting in the left-right direction. The front panel 30 is made up of a front plate 31, insertion holes 32 and 33 formed in the front plate 31 and through which the ignition buttons 11 and 12 are inserted, a plurality of support plates 32A, 32B, 33A and 33B extending rearward from the left and right hole edges of the insertion holes 32 and 33, bearing holes 34 formed in each of the plurality of support plates 32A, 32B, 33A and 33B and receiving the swinging shafts 11A and 12A, and slots extending rearward from the bearing holes 34 and opening rearward. The decorative panel 40 has an operation window 41A through which the ignition buttons 11, 12 are inserted with the pressing portions 11B, 12B exposed forward, and the swing shafts 11A, 12A have a substantially elliptical shape that is long in the first direction D1 when viewed from the side, and the swing shafts 11A, 12A are allowed to pass through the slit 35 when the extension direction of the slit 35 coincides with the first direction D1, and the swing shafts 11A, 12A are restricted from passing through the slit 35 when the extension direction of the slit 35 intersects with the first direction D1, and the decorative panel 40 is a front panel. When not attached to the front panel 30, the ignition buttons 11, 12 can swing downward by a first angle α from an upper restriction position where upward swing is restricted, and can reach the first position. When the ignition buttons 11, 12 are in the first position, the extension direction of the slit 35 coincides with the first direction D1. When the decorative panel 40 is attached to the front panel 30, the ignition buttons 11, 12 can swing downward by a second angle β, which is smaller than the first angle α, from the upper restriction position, and interfere with the lower edge of the operation window 41A, and cannot reach the first position.

[0042] With this configuration, the ignition buttons 11, 12 cannot reach the first position due to interference with the decorative panel 40, so even without providing any additional parts, the oscillating shafts 11A, 12A can be prevented from coming out of the bearing holes 34 and the ignition buttons 11, 12 can be prevented from slipping out rearward.

[0043] In the embodiment, the ignition buttons 11, 12 are provided with interference portions 11D, 12D that interfere with the lower edge of the operation window 41A, and protective portions 11F, 12F that fill the gap between the interference portions 11D, 12D and the lower edge of the operation window 41A when the ignition buttons 11, 12 are in the upper restricted position, and the protective portions 11F, 12F have an outer surface that is approximately arc-shaped with the swing axis 11A, 12A as the center when viewed from the side.

[0044] With this configuration, the provision of protective portions 11F, 12F prevents the interior of gas stove 1 from being seen through the gap between interference portions 11D, 12D and the lower edge of operation window 41A. Moreover, because protective portions 11F, 12F have outer surfaces that are substantially arc-shaped when viewed from the side, interference between protective portions 11F, 12F and operation window 41A can be avoided when ignition buttons 11, 12 are operated. Furthermore, the above configuration improves the design of ignition buttons 11, 12.

[0045] <Other embodiments> (1) In the above embodiment, two ignition buttons 11 and 12 are inserted through operation window 41A, but the number of ignition buttons inserted through the operation window may be only one.

[0046] (2) The shapes of the ignition button, front panel, decorative panel, etc. may be modified as appropriate within the scope that allows the objectives of this disclosure to be achieved. [Explanation of symbols]
