[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of a portion where a drop-in stove is attached to an attachment opening formed on a countertop or the like of a system kitchen.
[0002]
[Prior art]
Countertops of system kitchens where drop-in stoves are assembled are made of various materials such as wooden boards and artificial marble. Countertops made of materials with insufficient heat resistance are heated by the heat from the drop-in stove. When heated, it is subject to thermal damage such as discoloration.
[0003]
The drop-in stove (2) shown in FIG. 8 includes a main body case (20) formed in a box shape, and a top plate (41) that covers the upper end opening of the main body case (20) and is squeezed downward. And the five virtues (51) placed and accommodated on the top plate (41), and further, a gas burner (31) disposed in such a manner as to vertically penetrate the bottom wall of the top plate (41). The upper surfaces of the claw pieces (52) of the virtues (51) and the outer peripheral flange (42) at the upper end of the top plate (41) are substantially the same height. As a result, the top surface of the stove is finished to be flat so that the pan slides smoothly between the virtues (51) and the countertop (11).
[0004]
The drop-in stove (2) drops the body part into the mounting opening (12) formed in the countertop (11) of the system kitchen, and the hanging flange (23) protruding from the outer periphery of the upper end of the mounting opening (12). It is used by locking it to the periphery of 12) from above.
When the pan placed on the virtues (51) is heated by the gas burner (31), the combustion exhaust from the gas burner (31) flows along the bottom surface of the pan (91) to the outer peripheral side and is discharged to the outside. Is done.
[0005]
[Problems to be solved by the invention]
In this case, as shown by the imaginary line in the figure, when a large pan (91) is placed on the virtues (51), the combustion exhaust (A) discharged outside from the outer periphery of the pan bottom is the countertop ( The countertop (11) is heated in contact with 11). Therefore, when the countertop (11) is formed of a material having insufficient heat resistance, this may be subject to thermal damage such as discoloration.
[0006]
In particular, in the drop-in stove as shown in FIG. 8 in which the upper surface of the virtues (51) and the upper surface of the outer peripheral flange (42) of the top plate (41) are substantially the same height, the pan placed on the virtues (51) ( Since the difference in height between the bottom surface of 91) and the top surface of the countertop (11) is small, the combustion exhaust (A) is more likely to come into contact with the surface of the countertop (11), and the countertop (11) is thermally damaged. It is easy to receive.
[0007]
The present invention has been made in view of such a point, and the peripheral portion of the mounting opening (12) in the countertop (11) is thermally damaged by combustion exhaust from the drop-in stove (2) mounted thereon. It is an object to prevent receiving.
[0008]
[Means for Solving the Problems]
The technical means of the invention of claim 1 employed to solve the above-mentioned problem is as follows:
`` A frame-shaped heat insulating plate (7) arranged in a manner covering the periphery of the mounting opening (12) formed in the countertop (11) of the system kitchen from above,
The structure of the mounting part of the drop-in stove comprising a spacer for ensuring a heat insulation gap between the lower surface of the heat insulating plate (7) and the countertop (11),
The hanging flange (23) projecting from the outer periphery of the body of the drop-in stove (2) dropped into the mounting opening (12) is an inner periphery of the heat insulating plate (7) located above the countertop (11). Engaging the part from above,
The outer periphery of the heat insulating plate (7) is exposed around a drop-in stove dropped into the mounting opening (12),
In the periphery of the mounting opening (12) in the countertop (11), an insertion recess for inserting and mounting the heat insulating plate (7) in an outer peripheral restraint state is formed,
On the inner periphery of the heat insulating plate (7), an inner peripheral plate (62) that is opposed to the inner peripheral wall of the mounting opening (12) with a gap for ventilation is suspended. And
The heat insulating gap communicates with the atmosphere through the ventilation gap.
[0009]
The technical means operates as follows.
The above-mentioned heat insulating plate (7) for the drop-in stove mounting port is fitted and mounted in a fitting recess around the mounting port (12) formed on the countertop (11), and in this state in the mounting port (12) When dropping the body of the drop-in stove (2) from above, the suspension flange (23) formed on the outer periphery of the drop-in stove (2) is placed on the inner periphery of the heat insulating plate (7) from above. As a result, the drop-in stove (2) is attached to the countertop (11).
In this mounted state, the outer peripheral portion of the heat insulating plate (7) is exposed around the drop-in stove (2) on the upper surface of the countertop (11). Therefore, even if combustion exhaust is discharged from between the pan bottom of the large pan (91) to be heated and the drop-in stove (2), this is the heat insulating plate (7) exposed around the drop-in stove (2) The combustion exhaust does not directly contact the countertop (11).
[0010]
On the other hand, in the above technical means, a spacer for ensuring a heat insulating gap is provided between the lower surface of the heat insulating plate (7) in the mounted state and the counter top (11). The countertop (11) is more difficult to be heated by the air inside.
Furthermore, the inside of the heat insulation gap is through a ventilation gap between the inner peripheral plate (62) hanging from the inner periphery of the heat insulating plate (7) and the inner peripheral wall of the drop-in stove mounting port (12). Communicating with the atmosphere, the air in the ventilation gap is replaced with the outside air. Therefore, the temperature rise in the heat insulation gap can be more reliably suppressed.
[0011]
As in the second aspect of the invention, in the case where “the inner peripheral portion of the heat insulating plate (7) is lower than the outer side”, a drop-in stove (2) is provided on the inner peripheral portion of the heat insulating plate (7). It is used by engaging the suspension flange (23) on the outer periphery of the body.
Then, since the inner peripheral part of the heat insulating plate (7) with which the suspension flange (23) engages is lower than the outer side, the protrusion height of the drop-in stove (2) from the upper surface of the countertop (11) Becomes lower.
[0015]
【The invention's effect】
As described above, according to the first and second aspects of the present invention, the combustion exhaust discharged from between the drop-in stove (2) and the pan (91) mounted thereon directly passes the countertop (11). Therefore, it is possible to prevent thermal damage to the countertop (11).
[0016]
Further, since the counter top (11) is further prevented from being heated by the heat insulation gap between the lower surface of the heat insulating plate (7) and the counter top (11), the counter top (11) is further thermally damaged. It becomes difficult to receive.
Furthermore, since the air in the heat insulation gap between the lower surface of the heat insulating plate (7) and the counter top is replaced with outside air by the ventilation structure, the temperature rise in the heat insulation gap is further suppressed, so the counter top can be more reliably (11) Thermal damage is prevented.
[0017]
In the invention of claim 2, since the drop-in stove (2) protrudes from the upper surface of the countertop (11) can be lowered, the upper surface of the countertop (11) can be made flat, and the upper surface of the stove and the countertop (11) The pan (91) can be slid more smoothly between the upper surfaces.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the above invention will be described.
[About the first embodiment]
As shown in FIG. 1, the heat insulating plate (7) for the drop-in stove mounting opening according to the present embodiment is formed in a rectangular frame shape as a whole in plan view, and has an upper plate (61) and its inner peripheral edge. And an outer peripheral plate (63) as a spacer depending from the outer peripheral edge. FIG. 1 shows a state in which a part of the heat insulating plate (7) is cut out.
[0020]
The heat insulating plate (7) is obtained by drawing a stainless steel plate having a thickness of 0.7 mm to 1.0 mm, and the lateral width (S ₈ ) corresponding to the longitudinal direction of the countertop (11) is set to about 900 mm, The vertical width (S ₉ ) in the direction perpendicular to this is set to about 550 mm.
In addition, the width (S ₂ ) of the pair of lateral sides (66) and (67) extending in the longitudinal direction of the countertop (11) in the upper plate (61) is set to about 45 mm, and the other pair of longitudinal sides ( 68) The width (S ₁ ) of (69) is set to about 170 mm. The hanging length (S ₃ ) of the outer peripheral plate (63) is set to about 5 mm to 10 mm, and the hanging length (S ₄ ) of the inner peripheral plate (62) is set to about 10 mm to 30 mm. Further, in this embodiment, a region having a width of 20 mm inward from the outer edges of the horizontal side portions (66) and (67) and a region having a width of 155 mm inward from the outer edges of the vertical side portions (68) and (69), respectively. It is exposed around the drop-in stove (2) attached to the countertop (11). Accordingly, the exposed portion corresponds to the outer peripheral portion as the invention specific matter of the invention of claim 1, and the inner side corresponds to the inner peripheral portion as the invention specific matter of the invention of claim 1.
[0021]
The heat insulating plate (7) is mounted on a mounting port (12) having a shape as shown in FIG. 1 formed on the countertop (11).
A recess (14) (corresponding to the “insertion recess” which is the specific matter of the invention described above) is formed around the mounting opening (12) on the upper surface of the countertop (11). The heat insulating plate (7) is mounted in the lowered state.
Therefore, the height of the standing wall (15) on the outer periphery of the recess (14) matches the hanging length (S3) of the outer peripheral plate (63) in the heat insulating plate (7). The width (S7) of the pair of lateral sides (16), (17) corresponding to the longitudinal direction of the countertop (11) in the horizontal direction (66), (67) of the corresponding heat insulating plate (7) ) Is set slightly smaller than the width (S2), and the width (S6) of the vertical side portions (18) and (19) in the concave portion (14) is the vertical side of the corresponding heat insulating plate (7). It is set slightly smaller than the width (S1) of the parts (68) and (69). This is because when the heat insulating plate (7) is mounted on the mounting port (12), a ventilation path (K for replacing air described later between the inner peripheral wall of the mounting port (12) and the inner peripheral plate (62). This is for the purpose of forming a ventilation gap.
[0022]
In this case, the heat insulating plate (7) is opposed to the mounting port (12) formed in the countertop (11) of the system kitchen as shown in FIG. 1 from above, and the inner peripheral plate (62) is mounted on the mounting port. When inserted into (12), the outer peripheral plate (63) hanging from the outer peripheral edge of the upper plate (61) is placed in the vicinity of the standing wall (15) of the recess (14) in the countertop (11) (outer periphery) The heat insulating plate (7) does not move laterally and is positioned relative to the mounting opening (12) by the standing wall (15) and the outer peripheral plate (63). And, the caulking material (81) is filled in the gap between the outer peripheral plate (63) of the heat insulating plate (7) and the upright wall (15), and the spillage from the pan (91) is prevented from entering the portion. .
[0023]
Next, the body of the drop-in stove (2) is dropped into the center hole (74) of the heat insulating plate (7) from above, and the suspension flange (23) at the upper end of the body of the drop-in stove (2) is attached to the heat insulating plate. (7) When engaged with the upper plate (61), the assembly work of the drop-in stove (2) is completed as shown in FIG.
In this state, as shown in FIG. 2, the above-described outer peripheral portion of the heat insulating plate (7) is exposed around the outer peripheral flange (42) of the top plate (41) of the drop-in stove (2).
[0024]
Further, as shown in FIG. 2, there is a ventilation between the inner peripheral plate (62) hanging from the upper plate (61) of the heat insulating plate (7) and the inner peripheral wall of the mounting opening (12) formed in the countertop (11). A ventilation gap to be a path (K) is formed, and a heat insulation space (47) as a heat insulation gap between the upper plate (61) and the counter top (11) is provided via the ventilation path (K). It will be in communication with the atmosphere.
As shown by the imaginary line in FIG. 2, when a large pan (91) is placed on the virtues (51) and the gas burner (31) is combusted, the combustion exhaust from the gas burner (31) becomes the bottom of the pan (91). Then, the combustion exhaust gas is discharged from the gap between the pan (91) and the outer peripheral flange (42) of the top plate (41). Then, the discharged combustion exhaust (A) comes into contact with the outer peripheral portion (72) of the upper plate (61) of the heat insulating plate (7) and is prevented from coming into direct contact with the surface of the countertop (11). Therefore, even when the mounting opening (12) is formed of a material having insufficient heat resistance such as artificial marble, there is less inconvenience that it is thermally damaged or discolored.
[0025]
In addition, the inner peripheral plate (62) can block heat from the drop-in stove (2) side to the inner peripheral wall of the mounting opening (12) of the countertop (11), and the inner peripheral plate (62) Since it is bent from the plate (61), the strength of the inner peripheral portion of the upper plate (61) is improved, and the hanging flange (23) of the drop-in stove (2) can be reliably received. In addition, a ventilation gap serving as a ventilation path (K) is formed between the inner peripheral plate (62) of the heat insulating plate (7) and the inner peripheral wall of the mounting port (12). Air in the heat insulating space (47), which is a heat insulating gap formed between the upper plate (61) and the countertop (11), is replaced with outside air by the air passage (K). Therefore, the inconvenience of hot air in the heat insulating space (47) is avoided, and thermal damage to the countertop (11) is more reliably suppressed.
[0026]
Note that the air in the heat insulation space (47) naturally replaces the outside air through the ventilation path (K), but in order to ensure the replacement with the outside air, the main body case of the drop-in stove (2) ( In 20), it is desirable to form an intake hole at a position adjacent to the lower end of the lower end of the air passage (K) (position R in FIG. 2). When the outside air is sucked into the main body case (20) from the intake port in the draft at the time of combustion of the gas burner (31), the air in the heat insulating space (47) is also sucked through the air passage (K), This is because the air in the heat insulating space (47) can be actively replaced with the outside air. This also applies to each of the following embodiments.
