Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since the side filler described in Patent Document 1 is likely to be displaced from other parts, it may impair the aesthetic appearance of the oven.

[0005] An object of the present invention is to provide an oven that can prevent displacement of the side filler and improve the aesthetic appearance.

Means for Solving the Problems

[0006] The oven according to claim 1 is a built-in oven incorporated into the interior of a kitchen counter, comprising: an oven body having a baking chamber with an opening at the front; an oven door provided at the front of the baking chamber so as to be openable and closable and closing the opening when closed; an upper frame portion extending in the left-right direction, fixed to the upper front of the oven body such that both left and right ends protrude to the left and right of the oven door, and located above the oven door; and a pair of left and right side fillers fixed to the lower side of the upper frame portion and to the left and right sides of the oven body, respectively, wherein the lower surfaces of both left and right ends of the upper frame portion are provided with locking projections that protrude downward, and the upper ends of the locking projections are formed with a narrow portion whose width in the left-right direction is smaller than the width in the left-right direction of the other portion. The side filler comprises a front plate portion extending vertically with its surface facing forward, an inner plate portion extending rearward from a first side end of the front plate portion on the oven body side and forming a mounting portion with the oven body, and an outer plate portion extending rearward from a second side end of the front plate portion on the side opposite to the oven body, wherein the upper end of the inner plate portion is provided with an inner insertion piece formed to protrude inward toward the inside of the side filler and to be inserted into the left or right side of the narrow portion, and the upper end of the outer plate portion is provided with an outer insertion piece formed to protrude inward toward the inside of the side filler and to be inserted into the right or left side of the narrow portion, and the front surface of the locking projection below the narrow portion is provided with a contact portion that abuts against the rear surface of the front plate portion of the side filler.

[0007] The front of the narrow portion of the oven according to claim 2 is provided with a groove that is recessed toward the rear, and the upper end of the front plate portion is provided with a front insertion piece that is formed to protrude toward the rear, and the front insertion piece may be inserted into the groove from the front.

[0008] The side filler of the oven according to claim 3 may be mirror-symmetric with respect to a virtual plane obtained by cutting the middle portion of the front plate in the left-right direction. [Effects of the Invention]

[0009] According to the oven of claim 1, by inserting the inner insertion piece formed at the upper end of the inner plate portion and the outer insertion piece formed at the upper end of the outer plate portion into both the left and right sides of the insertion portion, it is possible to prevent the side filler from falling out and to prevent the side filler from shifting position in the left-right and up-down directions. Furthermore, by pushing the side filler backward until the rear surface of the front plate portion of the side filler contacts the contact portion provided on the front surface below the narrow part of the locking projection, further pushing is restricted, thereby enabling the front-rear positioning of the side filler relative to the upper frame portion. Then, by attaching the mounting portion provided on the inner plate portion of the positioned side filler to the side of the oven body, it is possible to prevent the side filler from shifting position relative to the upper frame. This ensures a good aesthetic appearance for the oven as a whole.

[0010] According to the oven of claim 2, since the front insertion piece is inserted into the groove from the front, the front insertion piece is positioned inside the groove. This more effectively prevents the side filler from shifting position and falling out.

[0011] According to the oven of claim 3, by making the side fillers mirror-symmetrical, the shapes of the left and right side fillers of the oven can be made identical. This reduces the manufacturing and management costs of the side fillers. [Brief explanation of the drawing]

[Figure 11] Figure 2 is a cross-sectional perspective view taken from the right rear, showing the W region broken at the center of the locking projection 61. [Modes for carrying out the invention]

[0013] Embodiments of the present invention will be described below. Unless otherwise specified, the device configurations described below are not intended to be the sole limiting factors, but are merely illustrative examples. The drawings are used to illustrate the technical features that the present invention may employ. In this embodiment, the front-to-back, left-to-right, and up-and-down orientations shown in the drawings will be used for explanation.

[0014] As shown in Figure 1, an opening (not shown) is provided on the upper surface of the countertop 2 of the kitchen counter 1, and a built-in cooktop 5 is installed by being dropped into this opening from above. A vertically elongated rectangular opening 3 is provided in the counter panel 4 at the front of the kitchen counter 1. The front of the built-in cooktop 5 is exposed at the upper inside of this opening 3. A gas oven 10 is installed below the built-in cooktop 5, and its front is exposed at the lower inside of the opening 3.

[0015] Referring to FIGS. 2 to 6, the structure of the gas oven 10 will be described. The gas oven 10 includes an oven main body 11, an oven door 15, an exhaust pipe 16, an upper frame portion 17, a pair of left and right side fillers 21, 22, etc. The oven main body 11 includes an outer box 13 and a baking chamber 14. The outer box 13 is a substantially rectangular parallelepiped metal box. A large rectangular opening (not shown) is provided near the upper side of the front surface of the outer box 13. The baking chamber 14 is provided inside the outer box 13 and near the upper side. A rectangular opening 14A is provided on the front surface of the baking chamber 14. An object to be cooked is accommodated inside the baking chamber 14. A rectangular frame portion 50 is fixed to the front surface of the outer box 13. The rectangular frame portion 50 includes an upper side portion (not shown), a lower side portion (not shown), a right side portion 51 (see FIGS. 5 and 6), and a left side portion 52 (see FIG. 6), and a rectangular opening 50A is formed at the center thereof. The opening 50A communicates with the opening 14A of the baking chamber 14 in the front-rear direction.

[0016] The oven door 15 is formed in a substantially rectangular shape in a front view and is provided so as to be vertically opened and closed about the lower end side in front of the lower part of the rectangular frame portion 50 (see FIG. 3). A handle 15A extending in the horizontal direction is provided at the upper part of the front surface of the oven door 15. The oven door 15 closes the opening 14A of the baking chamber 14 through the rectangular frame portion 50 in the closed state. Inside the outer box 13, a combustion device (not shown) including a gas burner is provided below the baking chamber 14. The high-temperature air heated by the combustion device flows into the baking chamber 14 by a fan (not shown). Thereby, the temperature inside the baking chamber 14 rises and the heating and cooking of the object to be cooked are performed.

[0017] The exhaust pipe 16 extends upward from the rear part of the baking chamber 14 and is connected to the lower part of the exhaust portion (not shown) of the built-in stove 5. The exhaust pipe 16 communicates with the inside of the baking chamber 14 and allows the high-temperature air flowing out from the inside of the baking chamber 14 to flow into the exhaust portion of the built-in stove 5. Thereby, the high-temperature air flowing out from the inside of the baking chamber 14 is discharged to the outside through the exhaust portion of the built-in stove 5.

[0018] The upper frame portion 17 is formed in a roughly rectangular prism shape extending in the left-right direction and is screwed to a mounting bracket (not shown) fixed to the upper front of the outer box 13. When the gas oven 10 is viewed from the front, the upper frame portion 17 is positioned above the oven door 15, and both left and right ends of the upper frame portion 17 protrude beyond the oven door 15 on both sides. The front of the upper frame portion 17 is positioned at approximately the same location as the front of the oven door 15 in the front-rear direction. An operation panel 17A is provided on the front of the upper frame portion 17. The operation panel 17A is equipped with various buttons, a display unit, LEDs, etc. A locking projection 61 is provided on the right side of the lower surface of the upper frame portion 17, protruding downwards. A locking projection 62 is provided on the left side of the lower surface of the upper frame portion 17, protruding downwards.

[0019] The locking projection 61 comprises a narrow portion 63 and a locking portion 64. The narrow portion 63 is provided at the upper end of the locking projection 61, and the locking portion 64 is provided below the narrow portion 63. The narrow portion 63 is the part whose width in the left-right direction is narrower than the width of the locking portion 64 in the left-right direction. A roughly U-shaped front groove 71 that opens forward in a side view is formed on the front side of the narrow portion 63. Therefore, the front surface of the narrow portion 63 is located behind the front surface of the upper frame portion 17. The locking portion 64 is formed in a roughly rectangular shape that is long in the front-rear direction in a bottom view. The left and right ends of the locking portion 64 protrude to the left and right of the left and right ends of the narrow portion 63. A contact portion 641 is provided at the front end of the locking portion 64. The contact portion 641 is formed to protrude forward from the front surface of the narrow portion 63 and is located behind the front surface of the upper frame portion 17 by the thickness of the front plate portion 23 of the side filler 21 described later. On the left side of the narrow section 63, a roughly U-shaped inner groove 72 is formed, opening to the left when viewed from the front. On the right side of the narrow section 63, a roughly U-shaped outer groove 73 is formed, opening to the right when viewed from the front. Note that the locking projection 62 on the left side is symmetrical to the locking projection 61, so its description is omitted.

[0020] The side fillers 21 and 22 are positioned below the left and right ends of the upper frame 17, respectively, and on the right and left sides of the oven door 15, and are screwed to the right side of the right side 51 and the left side of the left side 52 of the rectangular frame 50, respectively. The side fillers 21 and 22 are formed in a roughly rectangular shape that is elongated in the vertical direction when viewed from the front. When the gas oven 10 is viewed from the front, the side filler 21 closes the space between the right end of the oven door 15 and the right side wall 131 of the outer box 13. The side filler 22 closes the space between the left end of the oven door 15 and the left side wall 132 of the outer box 13.

[0021] Referring to Figures 7 and 8, the structures of the side fillers 21 and 22 will be described. As will be described later, the side fillers 21 and 22 are common parts, so in this embodiment, the structure of the right-side filler 21 will be described. The side filler 21 is a metal member that is elongated in the vertical direction when viewed from the front and is roughly U-shaped when viewed from above, with an opening towards the rear. The side filler 21 is formed, for example, by bending a metal plate. The side filler 21 comprises a front plate portion 23, an inner plate portion 24, and an outer plate portion 25.

[0022] The front panel 23 is formed in a roughly rectangular shape that is elongated vertically when viewed from the front, with its surface facing forward. The width of the front panel 23 in the left-right direction should be matched to, for example, the length of the gap between the right end of the oven door 15 and the right side wall 131 of the outer box 13.

[0023] The inner plate portion 24 extends rearward from the left end of the front plate portion 23 and is formed in a roughly rectangular shape that is long in the vertical direction when viewed from the left side. The connection portion between the inner plate portion 24 and the front plate portion 23 is bent in a roughly arc shape. The inner plate portion 24 is positioned on the side of the side filler 21 that is on the rectangular frame portion 50 side (the side of the firing chamber 14). An L-shaped portion 241 is provided at the corner where the rear end and upper end of the inner plate portion 24 intersect. An L-shaped portion 242 is provided at the corner where the rear end and lower end of the inner plate portion 24 intersect. A pair of upper and lower fixing holes 38 and 39 are provided on the vertically central side near the rear end of the inner plate portion 24, passing through in the left-right direction.

[0024] The outer plate portion 25 extends rearward from the right end of the front plate portion 23 and is formed in a roughly rectangular shape that is long in the vertical direction when viewed from the right side. The connection portion between the outer plate portion 25 and the front plate portion 23 is also bent in a roughly arc shape. The outer plate portion 25 is positioned on the side of the side filler 21 opposite to the rectangular frame portion 50 side (firing chamber 14 side). The width of the outer plate portion 25 in the front-rear direction is approximately the same as the width of the inner plate portion 24 in the front-rear direction. Two U-shaped grooves 244 and 245 are provided at the rear end of the outer plate portion 25, spaced apart in the vertical direction. The upper U-shaped groove 244 is located slightly above the midpoint of the outer plate portion 25 in the vertical direction and is positioned opposite the fixing hole 38 of the inner plate portion 24. The lower U-shaped groove 245 is located slightly below the midpoint of the outer plate portion 25 in the vertical direction and is positioned opposite the fixing hole 39 of the inner plate portion 24. The U-shaped grooves 244 and 245 are formed by a recess in a roughly U-shape when viewed from the side, extending forward from the rear end of the outer plate portion 25. The inner plate portion 24 and the outer plate portion 25 are roughly parallel to each other via the front plate portion 23, or the opening side may be slightly wider.

[0025] Furthermore, a first rectangular section 251 is formed on the rear end side of the outer plate section 25 above the U-shaped groove 244, a second rectangular section 252 is formed between the U-shaped grooves 244 and 245, and a third rectangular section 253 is formed on the rear end side below the U-shaped groove 245. The first rectangular section 251, the second rectangular section 252, and the third rectangular section 253 are roughly rectangular in shape when viewed from the side. In addition, a first inclined section 25A is provided at the rear end of the first rectangular section 251, projecting slightly inclined toward the inner plate section 24, a second inclined section 25B is provided at the rear end of the second rectangular section 252, projecting slightly inclined toward the inner plate section 24, and a third inclined section 25C is provided at the rear end of the third rectangular section 253, projecting slightly inclined toward the inner plate section 24.

[0026] Furthermore, a first insertion piece 26 projecting backward is provided at the rear end of the first inclined portion 25A. The first insertion piece 26 is formed in a roughly rectangular shape that is elongated vertically when viewed from the right side. A second insertion piece 27 projecting backward is provided at the rear end of the second inclined portion 25B. The second insertion piece 27 is formed in a roughly rectangular shape when viewed from the right side. A third insertion piece 28 projecting backward is provided at the rear end of the third inclined portion 25C. The third insertion piece 28 is formed in a roughly rectangular shape that is elongated vertically when viewed from the right side.

[0027] At the upper end of the side filler 21, a front insertion piece 31 is provided at the upper end of the front plate portion 23, and is formed to protrude rearward toward the inside of the side filler 21. The front insertion piece 31 is formed in a substantially triangular shape toward the rear. At the upper end of the inner plate portion 24, an inner insertion piece 32 is provided, and is formed to protrude to the right toward the inside of the side filler 21. The inner insertion piece 32 is formed in a substantially rectangular shape that is elongated in the front-rear direction when viewed from above. At the upper end of the outer plate portion 25, an outer insertion piece 33 is provided, and is formed to protrude to the left toward the inside of the side filler 22. The outer insertion piece 33 is formed in a substantially rectangular shape that is elongated in the front-rear direction when viewed from above, and faces the inner insertion piece 32 with a predetermined gap between them. The predetermined gap should be wide enough for the narrow portion 63 of the locking projection 61 to be inserted in the front-rear direction.

[0028] On the other hand, at the lower end of the side filler 21, a front insertion piece 35 is provided at the lower end of the front plate portion 23, and is formed to protrude rearward toward the inside of the side filler 21. An inner insertion piece 36 is provided at the lower end of the inner plate portion 24, and is formed to protrude to the right toward the inside of the side filler 21. An outer insertion piece 37 is provided at the lower end of the outer plate portion 25, and is formed to protrude to the left toward the inside of the side filler 22. These front insertion piece 35, inner insertion piece 36, and outer insertion piece 37 are the same shape as the front insertion piece 31, inner insertion piece 32, and outer insertion piece 33 provided at the upper end of the side filler 21.

[0029] The orientation of the side filler 21 shown in Figures 7 and 8 is the first mounting orientation. In the first mounting orientation, the side filler 21 is upright in the vertical direction, with the front plate portion 23 on the front side, the inner plate portion 24 on the left side, and the outer plate portion 25 on the right side, and the front insertion piece 31, inner insertion piece 32, and outer insertion piece 33 are positioned on the upper end side of the side filler 21. In this first mounting orientation, the side filler 21 is attached to the right side of the oven body 11.

[0030] The side filler 21 with the above shape is mirror-symmetric in a virtual plane P. The virtual plane P is a plane that cuts the middle of the side filler 21 in the vertical direction in the horizontal direction. As a result, by inverting the side filler 21 in the first mounting position vertically and horizontally, it can be used as the left side filler 22 (see Figures 5 and 9). The position of the side filler 22 in this position is the second mounting position. In the second mounting position, the side filler 22 is upright in the vertical direction, with the front plate portion 23 on the front side, the inner plate portion 24 on the right side, and the outer plate portion 25 on the left side, and the front insertion piece 35, inner insertion piece 36, and outer insertion piece 37 are positioned on the upper end side of the side filler 22. In this second mounting position, the side filler 22 is attached to the left side of the oven body 11. In this way, the side fillers 21 and 22 can be used as common parts, which reduces the manufacturing and management costs of the side fillers 21 and 22 compared to the case where the left and right side fillers have different shapes.

[0031] Next, the method for attaching the side fillers 21 and 22 to the gas oven 10 will be described. As shown in Figures 5 and 9, the worker holds the right-side filler 21 in the first attachment position, aligns the upper end of the side filler 21 with the locking projection 61 provided on the right side of the lower surface of the upper frame 17 from the front, and moves the side filler 21 toward the oven body 11 in that position (see the dashed arrow A1 shown in Figure 9). At this time, the first insertion piece 26, the second insertion piece 27, and the third insertion piece 28 of the side filler 21 are inserted into the inside of the right side wall 131 of the outer box 13.

[0032] Then, the inner insertion piece 32 of the side filler 21 is inserted from the front into the inner groove 72 on the left side of the locking projection 61, and the outer insertion piece 33 is inserted from the front into the outer groove 73 on the right side of the locking projection 61. The inner insertion piece 32 and the outer insertion piece 33 are locked to the upper surface of the locking portion 64 and are guided to slide substantially horizontally and backward along the upper surface. The inner insertion piece 32 and the outer insertion piece 33 are locked to the upper surface of the locking portion 64. This determines the vertical position of the side filler 21 and prevents it from falling out. Furthermore, since the narrow portion 63 of the locking projection 61 is sandwiched between the inner insertion piece 32 and the outer insertion piece 33, the horizontal position of the side filler 21 is also restricted. As a result, the gas oven 10 can prevent the side filler 21 from falling out while also preventing misalignment of the side filler 21 in the horizontal and vertical directions.

[0033] Then, the worker pushes the side filler 21 backward until the contact portion 641 of the locking portion 64 contacts the rear surface of the front plate portion 23 of the side filler 21. At this time, the front insertion piece 31 is inserted from the front into the front groove 71 of the locking projection 61. As a result, the front insertion piece 31 is also locked from above to the upper surface of the locking portion 64, which more effectively prevents the side filler 21 from being positioned vertically or falling off.

[0034] When the contact portion 641 comes into contact with the rear surface of the front plate portion 23, further pushing of the side filler 21 is restricted. At this time, the front position of the front plate portion 23 is approximately the same as the front position of the upper frame portion 17 and the front position of the oven door 15. This improves the aesthetic appearance of the gas oven 10 when viewed from the right. In this way, the gas oven 10 can automatically position the side filler 21 in the front-rear direction relative to the upper frame portion 17.

[0035] When the side filler 21 is positioned by the locking projection 61, the left side of the inner plate portion 24 contacts the right side of the right side portion 51 of the rectangular frame portion 50. The fixing holes 38 and 39 (see Figures 8 and 9) provided at the rear end of the inner plate portion 24 are positioned opposite the fixing holes 55 and 56 (see Figure 5) provided on the right side portion 51 of the rectangular frame portion 50. In this state, when the side filler 21 is viewed from the right, the positions of the fixing holes 38 and 39 of the inner plate portion 24 can be confirmed through the inside of the U-shaped grooves 244 and 245 of the outer plate portion 25. Therefore, the worker inserts screws 91 and 92 into the fixing holes 38 and 39 of the inner plate portion 24 via the U-shaped grooves 244 and 245 (see Figure 4) and fastens them to the fixing holes 55 and 56 provided on the right side portion 51, respectively. As a result, the inner plate portion 24 is fixed to the right side of the right side portion 51 of the rectangular frame portion 50.

[0036] Then, on the outer panel portion 25 side, the first insertion piece 26, the second insertion piece 27, and the third insertion piece 28 are inserted into the inside of the right side wall 131 of the outer box 13 and are locked to the inner surface of the right side wall 131. As a result, the inner panel portion 24 and the outer panel portion 25 are pushed closer together, and due to the bending rigidity of the metal plate, the side filler 21 is properly positioned between the right side portion 51 of the rectangular frame portion 50 and the right side wall 131 of the outer box 13, and is fixed to the right side of the oven body 11. In this way, the installation of the side filler 21 is completed.

[0037] Although not described in detail here, the method for attaching the left side filler 22 is the same as for the side filler 21. The worker holds the left side filler 22 in the second attachment position, aligns the upper end of the side filler 22 with the locking projection 62 provided on the left side of the lower surface of the upper frame 17 from the front, and moves the side filler 22 toward the oven body 11 in that position (see the dashed arrow A2 shown in Figure 9). Then, the front insertion piece 35, inner insertion piece 36, and outer insertion piece 37 provided on the upper end of the side filler 22 are inserted into the locking projection 62 provided on the left side of the lower surface of the upper frame 17, and the inner plate 24 is screwed and fixed to the left side of the left side 52 (see Figure 6) of the rectangular frame 50. This prevents the side fillers 21 and 22 from shifting relative to the upper frame 17, thus ensuring a good overall aesthetic appearance for the gas oven 10.

[0038] As described above, the gas oven 10 of this embodiment is a built-in gas oven that is incorporated inside the kitchen counter 1 and below the built-in cooktop 5. The gas oven 10 comprises an oven body 11, an oven door 15, an upper frame 17, and a pair of left and right side fillers 21 and 22. The oven body 11 includes a baking chamber 14 having an opening 14A on its front side. The oven door 15 is provided to open and close at the front of the baking chamber 14, and in the closed state, it closes the opening 14A. The upper frame 17 extends in the left-right direction and is fixed to the upper front of the oven body 11 such that both left and right ends protrude beyond the oven door 15 on both sides, and is positioned above the oven door 15. The side fillers 21 and 22 are fixed below the upper frame 17 and to both the left and right sides of the oven body 11, respectively. The lower surfaces of both left and right ends of the upper frame 17 are provided with downwardly projecting locking protrusions 61 and 62. A narrow portion 63 is formed at the upper end of the locking projection 61 (62). The width of the narrow portion 63 in the left-right direction is smaller than the width of the other parts in the left-right direction.

[0039] The side filler 21(22) comprises a front plate portion 23, an inner plate portion 24, and an outer plate portion 25. The front plate portion 23 extends vertically, with its surface facing forward. The inner plate portion 24 extends rearward from the left end of the front plate portion 23, which is on the oven body 11 side, and fixing holes 38 and 39 are provided at the rear end. The outer plate portion 25 extends rearward from the right end of the front plate portion 23, which is on the opposite side from the oven body 11. An inner insertion piece 32 is provided at the upper end of the inner plate portion 24. An outer insertion piece 33 is provided at the upper end of the outer plate portion 25. The inner insertion piece 32 and the outer insertion piece 33 are formed to protrude toward the inside of the side filler 21 in directions opposite to each other. In the right side filler 21, the inner insertion piece 32 is inserted from the front into the inner groove 72 on the left side of the narrow portion 63. The outer insertion piece 33 is inserted from the front into the outer groove 73 on the left side of the narrow section 63. A locking portion 64 is provided at the lower end of the locking projection 61. The locking portion 64 is wider in the left-right direction than the narrow section 63, and a contact portion 641 is provided on its front surface. The contact portion 641 contacts the rear surface of the front plate portion 23 of the side filler 21.

[0040] By having this configuration, the gas oven 10 can prevent the side filler 21 (22) from falling off while also preventing the side filler 21 from shifting position in the left-right and up-down directions. Furthermore, the side filler 21 is pushed backward until the rear surface of the front plate portion 23 of the side filler 21 contacts the contact portion 641 provided at the front end of the locking portion 64 of the locking projection 61. This prevents further pushing, allowing the side filler 21 to be positioned in the front-rear direction relative to the upper frame portion 17. Then, the fixing holes 38 and 39 provided in the inner plate portion 24 of the positioned side filler 21 are fixed to the right side of the right side portion 51 of the rectangular frame portion 50 of the oven body 11. As a result, the gas oven 10 can prevent the side filler 21 from shifting position relative to the upper frame portion 17, thus ensuring a good overall aesthetic appearance of the gas oven 10.

[0041] A front groove 71 is provided on the front side of the narrow portion 63 of the locking projection 61. The front groove 71 is recessed toward the rear. A front insertion piece 31 is provided at the upper end of the front plate portion 23 of the side filler 21(22), which is formed to protrude toward the rear. The front insertion piece 31 is inserted into the front groove 71 from the front. This more effectively prevents the side filler 21(22) from falling off the upper frame portion 17.

[0042] In the above description, the left end of the front plate portion 23 of the side filler 21 is an example of the "first side end" of the present invention. The right end of the front plate portion 23 is an example of the "second side end" of the present invention. The fixing holes 38 and 39 provided in the inner plate portion 24 are an example of the "mounting portion" of the present invention. The front side groove 71 is an example of the "groove portion" of the present invention.

[0043] It should be noted that the present invention is not limited to the above embodiments, and various modifications are possible. The oven door 15 of the gas oven 10 is designed to open and close vertically around its lower end as an axis, but the opening and closing method may be other than this. For example, it may be designed to open and close vertically around its upper end as an axis, or it may be designed to open and close horizontally around its right or left end as an axis.

[0044] The side fillers 21 and 22 are mirror-symmetric in the virtual plane P, but they do not have to be mirror-symmetric. The side fillers 21 and 22 do not have to be common parts.

[0045] In the above embodiment, the locking projection 61 has a front groove 71 on the front side of the narrow portion 63, and the front surface of the locking portion 64 below it is a contact portion 641. However, for example, the front groove 71 may be omitted, and part or all of the front surface of the locking projection 61 may be used as a contact portion.

[0046] A pair of upper and lower fixing holes 38 and 39 are provided on the rear end side of the inner plate portion 24 of the side filler 21, but the number and position of the fixing holes can be freely changed. Furthermore, although the fixing holes 38 and 39 are an example of the "mounting portion" of the present invention, the structure is not limited to fixing holes as long as the inner plate portion 24 is attached to the right side portion 51 of the rectangular frame portion 50, it may also be a claw portion or clip shape that engages with a locking portion provided on the right side portion 51, for example.

[0047] The first inclined portion 25A, the second inclined portion 25B, and the third inclined portion 25C provided on the outer plate portion 25 of the side filler 21 may be omitted.

[0048] The gas oven 10 in the above embodiment is installed below the built-in cooktop 5 on the kitchen counter 1, but its position on the kitchen counter 1 can be freely changed, and it does not have to be installed below the built-in cooktop 5. Also, the gas oven 10 is an example of the "oven" of the present invention, but it may be an electric oven. It may also have the function of a range. [Explanation of Symbols]
