Description

  The present invention relates to a top plate for a stove that covers the upper end open part of a stove body, and can be used as a top plate of a drop-in stove that is mounted in a state of being dropped into an opening established in a countertop of a system kitchen, for example. .

FIG. 6 is a plan view of a conventional stove top.
A front frame member (4a), a pair of left and right horizontal frame members (4b) (4c), and a rear frame member (4d) (having an exhaust window (44) for grilling) are assembled in a rectangular frame shape. A glass plate (5) having three burner-corresponding holes (57) is fitted in the outer peripheral frame (4).
FIG. 7 is a cross-sectional view of the mounting portion of the glass plate (5) with respect to the outer peripheral frame top plate (2).
The front frame member (4a), the horizontal frame members (4b), (4c), etc. that constitute the outer peripheral frame (4) are each composed of a physically independent member, and each of these frame members (4a) to (4a) to (4) (4d) is coupled on the back side of each corner portion (C1) (C1) (C2) (C2) of the glass plate (5) to be mounted.
As shown in FIG. 7, an inner peripheral flange (49) projects horizontally on the front frame member (4a), the horizontal frame member (4b) (4c), etc., and a glass plate is formed on the inner peripheral flange (49). The outer peripheral portion (59) of (5) is placed.

On the other hand, a metal back plate (B) parallel to the lower side of the glass plate (5) is provided adjacently, and the outer peripheral edge (h) of the back plate (B) is a front frame member ( 4a) and horizontal frame members (4b) and (4c) are inserted into horizontal grooves (462) formed in the inner periphery.
In this case, a wide inner peripheral flange (49) extending in the entire longitudinal direction is integrally projected on the inner side of each frame member (4a) (4b) (4c) etc., so that the glass plate (5) Of the frame material (4a) (4b) (4c) is increased in the width direction of the frame material (4a), (4b) and (4c) by the inner peripheral flange (49). There is little inconvenience to deform.

Further, since the back plate (B) is provided adjacent to the lower side of the glass plate (5), fragments when the glass plate (5) is damaged are received by the back plate (B), and the fragments are scattered. There are effects such as prevention.
However, in the above-mentioned conventional one, independent frame members (4a) (4b) (4c) (4d) are connected on the back side of each corner portion (C1) (C1) (C2) (C2) of the glass plate (5). Therefore, there is a problem that the assembling of the outer peripheral frame (4) takes time and the production efficiency of the top plate (2) is deteriorated as much as the connecting work is necessary.
JP 2003-343850 A

  Therefore, the outer peripheral frame (4) is formed by extruding a narrow aluminum mold material not provided with the inner peripheral flange (49), and bending the extruded long mold material into a rectangular frame shape. Fit the exhaust frame (the frame in which the exhaust window for the grill is opened), the glass plate (5) adjacent to this, and the back plate (B) on the back side of the glass plate (5) (hereinafter referred to as “Improved”) Can be considered. If it does in this way, an outer periphery frame (4) can be comprised only by bending one elongate type | mold material. Therefore, compared to the previously described conventional work that required the joining work of a plurality of frame members (4a) (4b) (4c) (4d), the production of the outer peripheral frame (4) takes less time, and the top plate The production efficiency of (2) is improved.

However, in the above improvement plan, the long die is capable of bending, so the inner peripheral flange (49) compared to the conventional frame members (4a) (4b) (4c) etc. described above. ) Is thin as much as it does not exist, and its deformation strength is weak. For this reason, this improved proposal has a problem that each side of the completed outer peripheral frame (4) is easily deformed outward (in a direction away from the center of the top plate).
The peripheral edge of the glass plate (5) and the outer peripheral frame (4) are bonded with a caulking agent (W) as shown in FIG. However, since the caulking agent (W) is flexible, the caulking agent (W) extends following the outward deformation of each side of the outer peripheral frame (4), or the outer peripheral frame (4) is deformed. As a result, the caulking agent (W) is left in a state in which a tensile stress is applied to the caulking agent (W). As a result, the adhesion state between the outer peripheral frame (4) and the glass plate (5) tends to deteriorate over time.

The present invention has been made in view of the above points.
`` A top plate for a stove covering the upper end opening of the stove body (1) having a gas burner,
An elongated frame (40) having a horizontal groove (462) formed on the side surface is bent into a rectangular frame shape so that the horizontal groove (462) is located on the inner periphery to form the outer frame (4). ,

The glass plate (5) is formed of ceramic glass and has three burner corresponding holes (57) described later formed concentrically with the gas burners (31), (32), and (33) described above. The upper and lower protective rings (54) and (55), which are protective covers (H), are attached to the peripheral edge of the burner corresponding hole (57).
《Upper and lower guard rings (54) (55)》
The mounting portions of the three protective covers (H) appearing in FIG. 2 have the same structure.
FIG. 3 illustrates a cross-sectional structure in a range from the arrangement of the protective cover (H) corresponding to the gas burner (31) appearing in FIG. 1 to the front side of the top plate (2).
As shown in FIG. 3, a seal packing (50) is fitted on the periphery of the burner corresponding hole (57) opened in the glass plate (5), and the mounting portion of the seal packing (50) is protected. It is sandwiched between upper and lower protective rings (54) and (55) that make up the cover (H), and this protects the periphery of the burner-corresponding hole (57) of the glass plate (5) that is easily broken. The damage is prevented.

The structure of the protective cover (H) will be further described in detail.
The metal upper protective ring (54) constituting the protective cover (H) is formed in an annular shape in plan view and has an inner peripheral hanging wall that bends downward from the inner periphery of the top annular plate (541). From the lower end of (540), the lower flange (542) is bent and protrudes inward. The inner periphery of the lower flange (542) is provided with six folded pieces (543) (543) arranged at a predetermined pitch in the circumferential direction, and the folded pieces (543) (543) Is wound around the inner peripheral edge of a lower protective ring (55), which will be described later.

  As shown in FIG. 2, the lower protective ring (55) made of metal constituting the protective cover (H) is formed in a square shape in plan view, and the lower protective ring is provided in the vicinity of the four corners. Four convex portions (552) and (552) formed by drawing down a metal plate (corresponding to the bottom wall of the protective cover (H)) constituting (55) are raised. As shown in FIG. 2, a central hole (553) is formed at the center of the lower protective ring (55) so as to overlap the central hole of the upper protective ring (54), and as shown in FIG. The outer peripheral edge (551) of the lower protective ring (55) is bent to the opposite side of the glass plate (5). As a result, when the outer peripheral edge (551) is a simple flat plate that is not bent to the opposite side of the glass plate (5), the metal plate end surface of the outer peripheral edge (551) of the lower protective ring (55) ) May collide with the glass plate (5) during assembly work and damage the glass plate (5), so the outer peripheral edge (551) should be on the opposite side of the glass plate (5). The bending is considered for the damage.

《Back plate (B)》
As shown in FIGS. 2 and 3, the central back plate (8) constituting the back plate (B) corresponds to the central hole (553) of the lower protective ring (55) constituting the protective cover (H). Back plate openings (81), (81) and (81) are opened, and top plate support ribs (82) and (82) formed by drawing the central back plate (8) upward are provided.
In addition, the vicinity of the back plate opening (81) established in the central back plate (8) is close to or in contact with the raised portion (552) raised on the lower surface of the lower protective ring (55). Even if the vicinity of the burner-corresponding hole (57) of the glass plate (5) is slightly bent downward due to the load of the pan placed on (31), the bottom of the center back plate (8) and the protective cover (H) The protective ring (55) is in partial contact with the convex portion (552). This reduces the contact area between the lower protective ring (55) and the lower surface of the lower protective ring (55) over the entire area compared to the central back plate (8). Heat is transferred through the back plate to prevent the outer peripheral frame (4) from becoming hot.
The top ridge lines (820) (820) of the top plate support ribs (82) (82) are formed in an arc shape. When the top ridge lines (820) and (820) are formed in an edge shape, the edge-shaped portion may collide with the glass plate (5) and damage it during assembly work, etc. It is designed to prevent scratches.

  The long side portion (84) on the front side of the central back plate (8) is inserted into the horizontal groove (462) that opens to the inner periphery of the outer peripheral frame (4), and the center of the long side portion (84). A pair of claws (85) and (85) (width 16 mm, height 6 mm) are bent and drooped at a predetermined interval. This claw (85) (85) is engaged with the vertical groove (463) that follows the back end of the horizontal groove (462) that opens to the inner periphery of the outer peripheral frame (4). ) Is prevented from bulging and deforming outward (in the direction away from the center). As a result, a caulking agent (W) described later applied between the outer peripheral edge of the glass plate (5) and the outer peripheral frame (4) (having a bonding function between the glass plate (5) and the outer peripheral frame (4)). A large load does not act, and the adhesion state between the outer peripheral frame (4) and the glass plate (5) is stabilized over a long period of time.

The central back plate (8) has screw insertion holes (86) and (86) (overlaid on the narrow groove (65) of the exhaust frame (6)) along the long side on the exhaust frame (6) side. The tapping screws (87) and (87) are screwed into the narrow grooves (65) on the lower surface of the exhaust frame (6) from the screw insertion holes (86) and (86), thereby the central back plate ( 8) is fixed to the exhaust frame (6). Specifically, as apparent from FIG. 4 showing a state in which a part of the top plate (2) is looked up obliquely from below, an L-shape formed on the long side of the rear side of the center back plate (8). A screw insertion hole (86) drilled in the stepped portion (89) is overlaid on the narrow groove (65) formed along the long side on the front side of the exhaust frame (6), and this overlapped portion is Screw in the tapping screws (87) and (87). Then, the tapping screws (87) and (87) are screwed in while engraving screws on the inner surface of the narrow groove (65), so that the central back plate (8) and the exhaust frame (6) are moved. Bonded with tapping screws (87) and (87).
A plurality of preliminary holes (88) (88) are formed in the vicinity of the screw insertion holes (86) (86), and tapping screws (87) (87) threaded from the screw insertion holes (86) are formed. ), If the work to form a screw groove on the inner wall of the narrow groove (65) fails (in the case of a screw fool), the tapping screws (87) (87) are attached using the spare holes (88) (88). It can be screwed in again.

  The outer peripheral edge of the side back plate (9) constituting the back plate (B) together with the central back plate (8) is also inserted into the horizontal groove (462) of the outer peripheral frame (4). Of the outer peripheral edge of the side back plate (9), the outer long side portion (93) (see FIG. 2) inserted into the horizontal groove (462) of the outer peripheral frame (4) has the horizontal groove (462). The claws (94) (94) engaged with the subsequent vertical groove (463) are bent and suspended. In this case, the pair of side edges (4f) (4g) of the outer peripheral frame (4) is the back plate (B) (the central back plate (8) and the side back plates (9), (9) are screws (80 ) And (80) are connected to each other in the direction to prevent separation, so that the sides (4f) and (4g) are more difficult to deform outwardly, thereby causing caulking. The adhesion state between the outer peripheral frame (4) and the glass plate (5) by the agent (W) is further stabilized over a long period of time.

Further, coupling pieces (92) and (92) stand up on the long side portion (91) of the side back plate (9) on the joint side with the central back plate (8). Then, the coupling pieces (83) and (83) on the center back plate (8) side corresponding to the coupling pieces (92) and (92) are overlapped, and both are coupled with screws (80) and (80). Then, the side back plate (9) and the center back plate (8) are connected and fixed to the left and right. In this case, as shown in FIG. 4, the region along the side of the central back plate (8) is a stepped portion (800) corresponding to the plate thickness over a certain width, and the central back plate (8) In the state where the side back plate (9) is connected, the stepped portion (800) overlaps with the long side portion of the side back plate (9). That is, the boundary between the center back plate (8) and the side back plate (9) is superposed vertically. This prevents light inside the stove body (1) from leaking upward from the boundary between the central back plate (8) and the side back plate (9) (for example, the light of the flame generated in the gas burner). However, the light is prevented from being transmitted through the glass plate (5).
In the present embodiment, the coupling pieces (92) (92) of the side back plate (9), the coupling pieces (83) (83) of the central back plate (8) side corresponding thereto, and The combination of the screws (80) and (80) to be combined corresponds to the “connecting means” which is the above-mentioned invention specific matter.

[Assembly work]
Next, the actual work of assembling the top plate (2) using each of the above components will be described.
First, the exhaust frame (6) is mounted in the outer peripheral frame (4) so as to follow the rear side (4i) of the outer peripheral frame (4) bent into a rectangular frame shape (see FIG. 5). At this time, it continues to the horizontal groove (462) in the butted portion (4e) (4e) of the rear side (4i) of the outer peripheral frame (4) (the portion where both ends of the long die (40) are butted) A claw (66) (height: 1.2 mm, width: 20 mm) at the rear edge of the exhaust frame (6) is engaged with the vertical groove (463). That is, the butted portion (4e) (4e) on the rear side (4i) of the outer peripheral frame (4) is expanded, and the vertical groove (463) (463) is moved to the claw (66) (66) from the left-right direction. The claws (66) are engaged so as to straddle both the vertical grooves (463) and (463). By this engagement, the rear side (4i) of the outer peripheral frame (4) can be prevented from being deformed outward. Next, the bottom wall of the rear side (4i) of the outer peripheral frame (4) and the rear edge of the exhaust frame (6) are appropriately crimped.

  Thereafter, the outer peripheral frame (4) to which the exhaust frame (6) is attached is turned over. That is, the outer peripheral frame (4) is set on the work table with the horizontal lip portion (40) (see FIG. 3) facing down. Next, after applying the caulking agent (W) made of silicon near the base of the horizontal lip portion (40), the peripheral edge of the glass plate (5) is overlapped with the caulking agent (W) application area. Engage with (40). Then, insert the long side (84) on the front side of the center back plate (8) into the horizontal groove (462) of the outer peripheral frame (4), and vertically insert the claws (85) (85) of the center back plate (8). Engage with the grooves (463) and (463). Specifically, as shown by an imaginary line in FIG. 3, the central back plate (8) is inclined to the posture in which the claw (85) is at the highest position, and the claw (85) is placed in the horizontal groove of the outer peripheral frame (4). The center back plate (85) is lowered to a posture along the glass plate (5) after engaging with the vertical groove (463) following (462). Thereafter, the screw insertion holes (86) (86) formed along the long side of the rear side of the center back plate (8) are overlapped with the narrow groove (65) of the exhaust frame (6) by the method described above. At the same time, the overlapped portion is coupled with tapping screws (87) and (87). At the same time, the outer peripheral edge of the side back plate (9) (9) is inserted into the horizontal groove (462) of the outer peripheral frame (4), and the nail (94) bent and suspended from the outer long side (93). ) (94) is engaged with the vertical groove (463) following the horizontal groove (462) formed in the side (4f) (4g) portion of the outer peripheral frame (4). Further, the connecting pieces (83) and (83) formed on both sides of the central back plate (8) are connected to the connecting pieces (92) and (92) of the side back plates (9) and (9) with screws (80) (80 ). Then, both sides (4f) (4g) of the outer peripheral frame (4) are connected to each other in the direction of preventing separation by the back plate (B) comprising the central back plate (8) and the side back plates (9) (9). It will be in the state. As a result, in addition to the front side (4h) of the outer peripheral frame (4) engaged with the claws (85) (85) on the front side of the back plate (B), both sides (4f) (4g) are further deformed outward. This makes it difficult to deform the outer peripheral frame (4) as a whole.

Further, in the present embodiment, the screw connection of the central back plate (8) and the side back plates (9) and (9) can be performed on the back side of the top plate (2), and the screws are connected to the top plate (2). It is possible to avoid unsightly exposure due to exposure to the surface of the surface.
Furthermore, since the back plate (B) is divided into three pieces, the central back plate (8) and the side back plates (9) and (9), the large single plate back plate (B) is divided into the outer peripheral frame (14). The back plate (B) can be easily attached as compared with the case of attaching to the back.

When the center back plate (8) and the side back plates (9) and (9) are attached to the outer peripheral frame (4), as shown in FIG. 3, the top plate support rib ( 82) (82) supports the glass plate (5) from below. Therefore, a special jig for fixing the glass plate (5) to the outer peripheral frame (4) becomes unnecessary until the caulking agent (W) is cured.
In the above embodiment, the present invention is applied to the top plate (2) of the drop-in stove mounted on the counter top of the system kitchen. However, the present invention can also be applied to the top plate of the table stove.
In the present embodiment, the exhaust frame (6) discharges exhaust from the grill portion (G) of the stove body (1), but an oven is provided below the stove body (1). In this case, the exhaust from the oven is discharged upward from the exhaust frame (6).
