Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gas stove, and more particularly to a gas stove in which sufficient secondary air can be supplied to a burner head even if the top plate is squeezed deeply.
[0002]
[Prior art]
FIG. 12 is a cross-sectional view of a main part of a gas stove mounted on the countertop (11) of the system kitchen, that is, a drop-in stove.
A stove main body (2) is mounted in an open state in the opening (12) formed in the countertop (11).
[0003]
A top plate (24) which is shallowly drawn downward is covered with a cover at the upper end opening of the main body case (26) of the stove body (2), and the bottom wall (240) of the top plate (24) is provided. The burner head (31) protrudes upward from the burner opening (25) formed in the above. A burner ring (4) for guiding the spillage onto the bottom wall (240) of the top plate (24) is fitted on the outer periphery of the cylindrical burner head (31). Further, the vicinity of the outer peripheral edge of the burner ring (4) is placed on an upright plate (250) in which the peripheral edge of the burner opening (25) formed in the top plate (24) is bent upright. The standing plate (250) is provided with through holes (251) and (251) for supplementing air supply during burner combustion.
[0004]
In this case, when the pan (A) is placed on the virtues (5) and the burner (3) is in a combustion state, secondary air for combustion is transferred from the upper outer periphery of the top plate (24) to the burner head (31). Is supplied to form a flame (F) in the flame hole (33a). On the other hand, as shown by the arrows in the figure, secondary air flows along the path connecting the lower space of the top plate (24) → the through hole (251) → the outer peripheral edge of the burner ring (4). Air supply is supplemented. In addition, the spilled spill from the pan (A) is guided and stored on the bottom wall (240) of the top plate (24) by the burner ring (4) and is prevented from falling into the stove body (2).
[0005]
Recently, the top surface of the countertop (11) can be finished flat by reducing the difference in height between the top surface of the countertop (11) in the system kitchen and the top of the drop-in stove attached to it (5). A gas stove is desired. In this case, since the pan (5) can be smoothly slid between the virtues (5) and the countertop (11), there is an advantage that the cooking operation is easy.
[0006]
[Problems to be solved by the invention]
However, the drop-in stove with the above structure has a problem that a sufficient flatness cannot be given to the upper surface of the countertop (11).
The above problem will be further described in detail.
To change the structure of the drop-in stove of FIG. 12 to a stove that finishes the top surface of the countertop flat, the top plate (24) of the stove is deeply squeezed to squeeze the five tops (5) and countertop (11) Set the top surface to approximately the same height. However, when the top plate (24) is squeezed deeply, the bottom wall of the pan (A) on the virtues (5) approaches the upper end opening (243) of the top plate (24). Combustion secondary air is less likely to enter the burner head (31) side from the gap between the outer periphery and the pan (A). In such a case, in addition to the path connecting the outer periphery of the top plate (24) and the pan (A) to the burner head (31), the space below the top plate (24) → the through hole (251) → the burner ring (4) Secondary air flows into the upper part of the top plate (24) through a path connected to the outer peripheral edge of the top plate (24), but in the figure, the air supplied from the through hole (251) to the outer peripheral edge of the burner ring (4) Is not actively guided to the flame hole (33a) side of the burner head (31), so in the stove having the structure of FIG. 12, if the central recess (242) of the top plate (24) is squeezed too deeply Proper combustion cannot be ensured, and a sufficient flatness cannot be imparted to the upper surface of the countertop (11).
[0007]
  According to the first aspect of the present invention, sufficient secondary air is supplied to the burner even if the top plate is deeply squeezed so that a sufficient flatness can be imparted to the upper surface of the countertop (11) of the system kitchen. That is the issue. Next, claim 3ThruThe subject of the invention of claim 5 will be described. When finishing the upper surface of the countertop (11) to be flat, the inside of the stove body is likely to be in a high temperature state as described later, but as a gas stove having a structure suitable for solving such inconvenience, a double top plate type There are things.
[0008]
In this structure, first and second openings that are vertically opposed to each other are formed on two top and bottom top plates provided in parallel at a predetermined interval, and a burner head is installed so as to penetrate the first and second openings. Provided. In this double top plate type, it is possible to prevent the radiant heat of the flame formed in the burner from being blocked by the upper top plate and transmitted to the lower top plate. Therefore, even when the upper surfaces of the five virtues and the countertop (11) are set to have substantially the same height and a flat feeling is generated, the lower ceiling plate is prevented from being overheated by the heat shielding effect of the upper ceiling plate. The gas cock, electronic components, and the like housed in the stove body below are not exposed to high temperatures. Therefore, the double top plate type gas stove has a structure suitable for finishing the upper surface of the countertop (11) in a flat feeling.
[0009]
However, in the case where the double top plate type gas stove is attached to the opening formed in the countertop (11) so that a flat feeling is generated on the upper surface of the countertop (11), as described above, Since the bottom of the pot on Gotoku approaches the top plate, the supply of secondary air to the burner is insufficient. Therefore, even with this double top plate type, there remains a problem that a sufficient flatness cannot be imparted to the upper surface of the countertop (11).
[0010]
  Claim 3ThruThe invention of claim 5 has been made in view of such points, and the top plate of the double-top gas stove is deeply squeezed so as to give a sufficient flat feeling to the upper surface of the countertop (11) of the system kitchen. However, an object of the present invention is to supply sufficient secondary air to the burner.

Therefore, in this embodiment, the top plate (8) on which the burner ring (4) (4) (4) is placed corresponds to the top plate as the invention specific matter of the invention of claim 1.
[0024]
Hereinafter, the details of each of the above parts will be described.
[About stove body (2)]
As shown in FIGS. 1 and 2, the main body case (26) of the stove body (2) is formed in a rectangular box shape that opens upward, and a flange (22) is provided around the upper end of the case. In addition, a rubber packing (23) is attached to the peripheral edge of the flange (22) as shown in FIG.
[0025]
Further, three burners (3), (3), and (3) are accommodated in the main body case (26), and the burner (3) is an upper half formed by drawing a sheet metal having a predetermined shape. (35) is a so-called sheet metal burner in which the lower half (36) faces and is integrated, and a burner cap (34) is attached to the central hole (32) of the cylindrical burner head (31). Thus, the spilled portion is prevented from falling into the main body case (26) through the central hole (32). Further, on the upper surface of the burner head (31), there are formed gas outlets (33), (33) facing the outer peripheral bottom face (340) of the burner cap (34), and the gas outlets (33), (33) ) And the gap between the burner head (31) and the burner cap (34) is a flame hole (33a) (33a).
[0026]
Further, the grill part (60) is incorporated into the grill opening (61) on the front surface of the stove body (2) to form the grill part (6).
[About lower plate (7)]
As shown in FIG. 1, the lower top plate (7) to be covered by the upper end opening of the stove body (2) has its center portion squeezed downward and a flange (74) on the outer periphery of the upper end. Is installed around.
[0027]
The bottom plate (70) of the lower top plate (7) has three first openings (71) having a diameter larger than the outer diameter of the burner heads (31) (31) of the burner (3) (3) described above. ) (71) (71) are drilled so that the first opening (71) is removed from the outer peripheral side of the burner head (31) of each burner (3) with a predetermined gap. It has a structure that can be fitted.
Further, the bottom plate (70) of the lower top plate (7) is slightly bent upward in the vicinity of the inner peripheral edge (72) of the first opening (71), so that the inner peripheral edge (72) It is higher than the bottom plate (70). The outer side (the direction away from the first opening (71)) of the inner peripheral edge (72) is a spilled reservoir for storing the spilled spill. As a result, the spillage slightly falling on the lower top plate (7) is accumulated on the bottom plate (70) to prevent the spillage from leaking from the first opening (71) into the stove body (2). It is out. Therefore, in this embodiment, the boiled spillage storage part is a boiled spillage storage means as the invention specific matter of the invention of claim 1 and a boiled food which is the invention specific matter of the invention of claim 3 described as a subordinate concept thereof. Corresponds to the recess for storage.
[0028]
Further, a grill exhaust port (75) for discharging combustion exhaust from the grill portion (6) is formed at the rear portion of the bottom plate (70) of the lower top plate (7).
[About the top plate (8)]
The upper top plate (8) mounted on the upper surface of the lower top plate (7) (corresponding to the top plate as the invention specific matter of the invention of claim 1) has its central portion squeezed downward. In addition, a drooping plate (83) that is bent downward and has a plurality of vent holes (87) and (87) is continuously provided on the outer peripheral edge of the outer peripheral flange (84) protruding from the upper end. The hanging plate (83) is mounted on a stepped portion (76) formed in the vicinity of the outer periphery of the bottom plate (70) of the lower top plate (7), and the hanging plate (83 ) Is set to a predetermined length, whereby a predetermined gap (S) is formed between the lower top plate (7) and the bottom plate (70) (80) of the upper top plate (8). It is like that. The gap (S) is formed in order to prevent overheating of the bottom plate (70) of the lower top plate (7) and to cause spillage that may slightly flow onto the bottom plate (70) of the lower top plate (7). This is to allow storage on the lower top plate.
[0029]
The bottom plate (80) of the top plate (8) has three second openings (81) (81) (81) having a diameter larger than the outer diameter of the burner head (31). As a result, the second opening (81) can be fitted over the outer peripheral side of the burner head (31) of each burner (3) with a predetermined gap. Therefore, in this embodiment, the second opening (81) corresponds to the opening which is the invention specific matter of the invention of claim 1. The diameter of each of the second openings (81) is set larger than the diameter of the first opening (71) of the lower top plate (7) corresponding thereto.
[0030]
Further, the bottom plate (80) of the upper top plate (8) is slightly bent upward in the vicinity of the inner peripheral edge (82) of the second opening (81), whereby the inner peripheral edge (82) is bent to the bottom plate (80). 80) Made of higher. Thereby, the outer side (the direction away from the second opening (81)) from the inner peripheral edge (82) is a spilled reservoir that stores the spilled spill.
[Burnering (4)]
As shown in FIGS. 4 and 5, the burner ring (4) placed on the upper top plate (8) has a circular shape with a mounting hole (40) drilled in the center. The diameter of (40) substantially matches the diameter of the outer peripheral side portion of the burner head (31). As a result, the burner ring (4) can be fitted onto the burner head (31) almost tightly, so that the spilled intrusion may enter the boundary between the outer peripheral side of the burner head (31) and the burner ring (4). I try to prevent it. Although it is easy to set the shape of the burner head (31) in the casting burner, the burner head (31) of the sheet metal burner is generally formed in a simple cylindrical shape due to manufacturing limitations as in this embodiment. Has been. Therefore, since the burner ring (4) cannot be supported by the simple cylindrical burner head (31) itself, the burner ring (4) is placed on the upper top plate (8) as described above. Yes. The burner ring (4) is externally fitted to the burner head (31) so as to be inserted and removed.
[0031]
In the middle of the burner ring (4) in the radial direction, a plurality of slit-shaped ventilation through holes (41) (41) arranged in the circumferential direction are formed. When the burner ring (4) is externally fitted to the burner head (31), as shown in FIG. 3, the vent holes (41) (41) are connected to the second opening (81) of the upper top plate (8). ) To face the bottom plate (70) of the lower top plate (7) from above. That is, the ventilation through holes (41) and (41) are opposed to the upper surface of the lower top plate (7) and become lower as the distance from the first opening (71) increases. Boiled spills that have entered through the vent hole (41) are stored on the bottom plate (70). Therefore, in this embodiment, as described above, the region of the upper surface of the lower ceiling plate (7), which becomes lower as the distance from the first opening (71) increases, is as set forth in claims 1 and 3. It corresponds to the boiled spillage storage means and the boiled spillage recess as the invention specific matter of the invention.
[0032]
Also, the inner ring part (43) and the outer ring part (44) located inside and outside the arrangement area of the ventilation through holes (41) and (41) are the former inner ring part (43) and the outer ring part of the latter. It is bent so as to fall below the portion (44), and thereby the ventilation through hole (41) is configured to face the burner head (31) side. The outer ring portion (44) is inclined so as to gradually increase from the outer peripheral portion toward the ventilation through-hole (41). Therefore, as will be described later, when the secondary air for combustion to the burner (3) hits the bottom surface of the outer ring portion (44), this is from the side of the ventilation through hole (41) to the burner head (31). It is guided to the flame hole (33a) and blows out toward the flame hole (33a).
[0033]
The burner ring (4) has its outer ring portion (44) placed on the upper top plate (8), so that the inner ring portion (43) is separated from the inner peripheral edge (72) of the lower top plate (7). It is located away, and this gap serves as an air passage for secondary air.
[About Gotoku (5)]
The five virtues (5) are a rectangular frame (51) disposed along the inner side of the outer peripheral standing part (73) of the lower top plate (7), and a claw piece extending from the upper side to the vicinity of the burner head (31). (52) (52).
[Operation of gas stove]
The gas stove is used by being dropped into the opening (12) formed in the countertop (11) of the system kitchen. That is, as shown in FIGS. 2 and 3, the body of the stove body (2) is dropped into the opening (12) of the countertop (11) and the body case (26) of the stove body (2) is removed. The flange (22) protruding from the outer periphery of the upper end is used by engaging with the peripheral edge of the opening (12) opened in the countertop (11).
[0034]
When the operation knob (56) of the stove body (2) is operated, gas is ejected from the flame hole (33a) of the burner head (31), and an ignition device (not shown) is operated to start a combustion operation. Then, due to the draft phenomenon, as shown by the arrow (X) in FIG. 3, the lower space of the lower top plate (7) → the first opening (71) → the vent hole for the burner ring (4) (41) → the burner Combustion secondary air is supplied through a path connected to the flame hole (33a) of the head (31), and a flame (F) is formed in the flame hole (33a) portion of the burner head (31). At this time, the secondary air flowing between the lower top plate (7) and the upper top plate (8) is inclined so that it becomes higher as it approaches the burner head (31), and the outer ring part of the burner ring (4) is inclined. (44) Since the outer ring portion (44) is guided by the lower surface and moves to the flame hole (33a) side, the outer ring portion (44) functions as a guide member described as the invention specific matters of the inventions of claims 1 and 3. .
[0035]
  Next, an embodiment of the invention of claim 4 will be described with reference to FIG.
  As shown in FIG. 6, when the inner peripheral edge of the second opening (81) formed in the bottom plate (80) of the upper top plate (8) extends to the vent hole (41) of the burner ring (4) The secondary air is guided to the lower surface of the bottom plate (80) and discharged from the ventilation through hole (41). In this case, the bottom air (80) in the vicinity of the second opening (81) is discharged. The bottom isIt was described as the invention specific matter of the invention of claim 4It functions as the guide member.
[0036]
On the other hand, when spilling occurs from the pan (A) placed on the virtues (5), most of it falls to the bottom plate (80) of the upper top plate (8) and is stored in that portion. On the other hand, the boiled spill that fell on the inner ring part (43) of the burner ring (4) flows to the outer peripheral side and flows from the vent hole (41) to the bottom plate (7) of the lower top plate (7) below it. 70) Leaking up. Then, since the inner peripheral edge (72) portion of the first opening (71) formed in the lower top plate (7) is higher than the bottom plate (70), the simmering of the lower top plate (7) Accumulate on the bottom plate (70). In this case, since the radiant heat of the flame (F) formed in the flame hole (33a) is blocked by the upper top plate (8), the above-mentioned boiled spillage collected on the lower top plate (7) is less likely to be overheated. Thus, there is less concern that the boiled spills may burn on the lower top plate (7).
[0037]
Therefore, when cleaning the spilled spill, remove the burner ring (4) from the burner head (31) with its outer ring part (44), remove the top plate (8), wash them, These can be easily cleaned simply by wiping off the spillage collected on the bottom plate (70) of the lower top plate (7).
In addition, the double top plate structure of the lower top plate (7) and the upper top plate (8) suppresses the temperature rise of the bottom plate (70) of the lower top plate (7), so the inside of the stove body (2) is hot. Thus, the electronic components for control in the stove main body (2) are not easily affected by thermal adverse effects.
[0038]
Next, an embodiment corresponding to the invention of claim 1 and the subordinate concept of claim 2 will be described with reference to FIGS.
The diameters of the first opening (71) of the lower top plate (7) and the second opening (81) of the upper top plate (8) are set to be larger than the outer diameter of the burner head (31). The point that a gap is formed between the inner peripheral edges (72) and (82) of the second opening (81) and the outer peripheral side portion of the burner head (31) is the same as in the above-described embodiment. In this case, the diameter of the second opening (81) of the upper top plate (8) and the diameter of the first opening (71) of the lower top plate (7) may be larger. In the present embodiment, as in the above-described embodiment, the upper top plate (8) and the second opening (82) formed in the upper top plate (8) and the top plate as the invention specific matter of the invention of claim 1 and It corresponds to each opening.
[0039]
On the other hand, the burner ring (4) according to this embodiment has substantially the same structure as that of FIGS. 4 and 5, but as shown in FIGS. 7 and 8, the outer peripheral edge (43) of the inner ring part (43) 430) extends outward from the inner peripheral edge (440) of the outer ring portion (44) and is formed in an undercut shape. In order to manufacture the burner ring (4), as shown in FIG. 9, first, the inner ring portion (43) continuous through the ventilation through hole (41) inside the outer ring portion (44) is further provided. An intermediate product (a) having an upper curved portion (46) formed therein is once manufactured. Thereafter, the upper curved portion (46) is forcibly pushed down as shown by arrow (Y) in the same figure to (b), and in this state, the first to third molds (100) (101) When the curved portion (46) is further pushed down by being sandwiched between (102), a portion corresponding to the inner ring (43) enters below the outer ring (44) to form an undercut portion (45). Thereafter, when the inside of the portion corresponding to the inner ring (43) is punched out by a press, the burner ring (4) as shown in FIG. 8 is completed.
[0040]
In this case, the outer peripheral edge (430) of the inner ring portion (43) of the burner ring (4) is a second plate formed on the bottom plate (80) of the upper top plate (8) as shown in FIG. It extends from the inner peripheral edge (82) of the opening (81) to the boiled spill reservoir. The burner ring (4) is placed on the upper top plate (8) at the outer peripheral end of the outer ring portion (44), and the inner ring (43) is the second opening (81) of the upper top plate (8).

That is, the secondary air is guided to the lower surface of the outer ring portion (44) as a guide member for regulating the flow direction of the secondary air and moves to the flame hole (33a) side. Proper combustion of the gas is ensured.
[0043]
Next, an embodiment corresponding to the invention of claim 5 will be described with reference to FIGS.
The diameters of the first opening (71) and the second opening (81) of the lower top plate (7) and the upper top plate (8) are set to be larger than the outer diameter of the burner head (31). The point that a gap is formed between the inner peripheral edge (72) (82) of the second opening (81) and the outer peripheral side portion of the burner head (31) is the same as in the above-described embodiment. Then, the diameter of the second opening (81) of the upper top plate (8) is smaller than the diameter of the first opening (71) of the lower top plate (7).
[0044]
On the other hand, the burner ring (4) according to this embodiment is placed on the inner peripheral edge (72) of the lower ceiling plate (7), and its planar shape is formed in a triangular shape, and in the center thereof. As in the embodiment described above, a mounting hole (40) is formed on the outer periphery of the burner head (31) so that it fits closely. The three sides of the outer periphery of the burner ring (4) formed in a plane triangle shape and the peripheral edge of the mounting hole (40) are bent upward to form upright pieces (47) and (48). In addition, on the upper surface of the guide groove (49) sandwiched between the upright pieces (47), (47), (47), and (48), the inner peripheral edge of the second opening (81) formed in the upper top plate (8) ( 82) is facing from above. Therefore, when the burner ring (4) fitted to the burner head (31) is viewed from above, the burner ring (4) is connected to the peripheral edge of the second opening (81) of the upper top plate (8). The burner head (31) completely overlaps the gap with the outer periphery.
[0045]
In addition, between the standing piece (47) (47) on the outer periphery of the burner ring (4) and the inner periphery (72) of the first opening (71) of the lower top plate (7), there is no connection to the burner (3). A ventilation gap (K) through which the secondary air rises is formed. That is, when the burner ring (4) fitted on the burner head (31) is viewed from above, it partially overlaps the gap between the peripheral edge of the first opening (71) and the outer periphery of the burner head (31). It is in a state. The three open ends of the guide groove (49) on the upper surface of the burner ring (4) are lowered as they move away from the upper surface of the lower top plate (7), that is, the first opening (71), That is, it is connected to the concave portion for spilling and storing.
[0046]
In this case, as indicated by the arrow (B) in FIG. 10, the lower space of the lower top plate (7) → the first opening (71) → the second opening (81) of the upper top plate (8) → the flame hole (33a ) And secondary air.
On the other hand, boiled spills from pan (A) placed on Gotoku (5) are stored on the bottom plate (80) of the top plate (8) and fallen from the second opening (81). Flows from the guide groove (49) of the burner ring (4) to the bottom plate (70) of the lower top plate (7) through the downstream end opening portion (46) and accumulates on the bottom plate (70).
[0047]
In FIGS. 10 and 11, when the guide groove (49) has a downward slope that decreases as it goes outward from the mounting hole (40), the spillage that has fallen into the guide groove (49) is caused by the slope. Naturally flows outward. Therefore, the above-mentioned standing piece (48) is not necessary for such a device.
Further, in the above, the planar shape of the burner ring (4) is formed in a substantially triangular shape, but it may be a quadrangular or pentagonal polygon, and the main point is that the bottom plate (7) It suffices if a ventilation gap (K) can be formed between the opening (71) and the outer periphery of the burner ring (4).
[0048]
In addition, although the said embodiment demonstrated the drop-in stove of the format with which it mounts | wears with the countertop (11) of a system kitchen exemplarily, this invention can be applied to the table stove mounted and used on a cooking table etc. Needless to say.
