[0022]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
[0023]
FIG. 1 is a cross-sectional view showing an embodiment of a stove of the present invention. The stove 10 is a drop-in type glass top stove, and the top surface of the stove body 12 is covered with a top plate 14 using a heat-resistant glass plate (ceramic glass). An opening 16 to be disposed is opened. An annular packing 20 is attached to the peripheral edge portion 14 a of the opening 16 of the top plate 14 so that the boiled juice does not fall into the opening 16, and the juice receiving tray 22 is placed on the packing 20. The five virtues 24 are placed. In this embodiment, since a glass plate is used for the top plate 14, the packing 20 is also a protector for the opening peripheral edge portion 14 a of the top plate 14.
[0024]
The soup pan 22 includes a soup pool portion 22b around a window hole 22a through which the head 18a of the gas burner 18 is inserted. As shown in FIG. 4 showing the details of the D portion of FIG. 1, a flange portion 22d extending horizontally outward is formed at the upper end of the outer peripheral rising wall 22c of the soup pool portion 22b, and a hanging wall 22e is further formed from the outer periphery. Is formed. When the juice receiving tray 22 is placed on the packing 20, the lower end of the hanging wall 22 e does not reach the top plate 14 and has a gap X with the top plate 14. In this example, a step portion 22f is formed on the outer peripheral rising wall 22c, and the virtues 24 are placed on the step portion 22f.
[0025]
In addition, 22g is an inner peripheral rising wall of the juice reservoir 22b. A gas cock 28 is connected to a gas supply pipe 30 connected to an inlet 30 a attached to the bottom of the stove body 12. A knob 23 on the top plate 14 is attached to an operation shaft 25 provided in the gas cock 28, and the burner 18 is ignited, extinguished, and heat power adjusted by the gas cock 28 via the knob 23. 26 is a thermocouple for detecting fire extinguishing, and 27 is a spark plug.
[0026]
The stove main body 12 is suspended by the opening 3 of the worktop 2 by engaging the flange 12a at the upper end of the peripheral wall of the stove main body 12 with the peripheral upper surface of the opening 3 provided in the worktop 2 of the system kitchen. . In order to prevent intrusion of water, broth or the like into the stove main body 12 from the upper surface of the work top 2, a packing 12b is interposed between the top plate 14 and the work top 2 over the entire circumference.
[0027]
The packing 20 is a ring having a substantially U-shaped cross section consisting of an upper piece 20b1, a lower piece 20b2 and a side piece 20b3, and has a groove 20a surrounded by these three pieces on the outer peripheral side surface. The peripheral edge portion 14a of the opening 16 of the top plate 14 is fitted into the concave groove 20a. The soup pan 22 is disposed in the opening 16 of the top plate 14 with its flange portion 22 d placed on the upper piece 20 b 1 of the packing 20.
[0028]
According to the present embodiment, as shown in FIGS. 2 and 3, 12 convex portions 21 </ b> T are provided at equal intervals in the circumferential direction on the bowl-shaped upper piece portion 20 b 1 on which the flange portion 22 d of the juice tray 22 is placed. Individually formed. Accordingly, the upper side portion 20b1 of the packing 20 includes a low wall 21L having a height L between the convex portions 21T and a high wall 21H having a height H higher than the low wall 21L by the convex portion 21T. The upper surface 21 of 20 becomes an uneven shape in which a high surface and a low surface are formed, and the flange 22d of the soup pan 22 is received by the high wall 21H, and the low surface and the flange 22d of the low wall 21L. A gap is formed between and the intake portion 32. The intake portion 32 communicates with the inside of the stove main body 12 through the opening 16 of the top plate 14.
[0029]
By the way, the hanging wall 22e provided in the juice receiving tray 22 is located outside the inlet 32a of the intake portion 32 with a gap Y therebetween. Therefore, the drooping wall 22e has a draining function, and the broth dropped on the outer peripheral edge of the soup pan 22 drops on the drooping wall 22e and does not enter the intake section 32. Further, the hanging wall 22e covers the complicated shape of the packing 20 in which the high wall and the low wall are alternately arranged, and the packing 20 is in a clean state in appearance.
[0030]
Therefore, when the gas is burned by the gas burner 18 of the stove 10, the combustion air is sucked from above the top plate 14 through the intake portion 32 and supplied into the stove main body 12 through the opening 16. Thus, if the intake part 32 is formed between the packing 20 and the flange part 22d of the soup pan 22, the combustion air can be sucked in from the upper side of the top plate 14, so that the airtightness of the stove body 12 is high. However, sufficient combustion air can be sucked and supplied into the stove body 12. Moreover, since the intake part 32 is formed between the flange part 22d of the soup saucer 22 only by providing the convex part 21T at intervals on the upper surface 21 of the packing 20, the intake structure is also simple.
[0031]
Further, in the present embodiment, an outward projecting portion 21S projecting outward from the outer surface of the lower wall 21L is formed on the outer surface of the high wall 21H of the packing 20 so as to be higher than the inlet 32a of the intake portion 32. The outer surface of the wall 21H was exposed outward. In FIG. 4, if the position of the soup pan 22 is shifted in the radial direction, the drooping wall 22 e of the soup pan 22 may block the inlet 32 a of the air intake portion 32, but on the outer surface of the high wall 21 </ b> H of the upper piece 20 b 1. If the outward projecting portion 21S is provided, the hanging wall 22e comes into contact with the outward projecting portion 21S, so that a gap Y between the inlet 32a of the intake portion 32 and the suspended wall 22e is reliably secured, and the intake portion inlet 32a. Will not be blocked.
[0032]
In this embodiment, the outward projecting portion 21S is provided on the entire outer peripheral side surface of the high wall portion 21H, but it may be provided only on the outer peripheral side surface of the convex portion 21T. In addition, although the inner peripheral side surface of the convex portion 21T recedes outward in the high wall portion 21H, it can be an inner peripheral surface on the same position as the inner peripheral side surface 20c.
[0033]
Further, even when the soup pan 22 is displaced as described above, at the opposite position starting from the center of the soup pan 22, there is a gap between the inner peripheral side surface 20 c of the packing 20 and the outer peripheral rising wall 22 c of the soup pan 22. Although the gap Z is secured, the gap Z is narrowed. Therefore, a cut portion 20cS that is retracted outward from the lower portion 20cB is formed at least inside the lower wall 201L of the inner peripheral side surface 20c of the packing 20. In this way, more gaps Z between the inner peripheral side surface 20c of the packing 20 and the outer peripheral rising wall 22c of the soup pan 22 can be formed.
[0034]
FIG. 5 shows another embodiment of the packing, and the basic structure is the same as that of the packing 20, but in this embodiment, the inner peripheral surface of the high wall 201H on the inner peripheral side surface 200c of the packing 200. An inner protrusion 201S that protrudes inward from the inner peripheral surface of the lower wall 201L is formed, and the inner peripheral surface of the high wall 201H protrudes inward from the inner peripheral surface of the lower wall 20L. There is no outward protrusion protruding outward on the outer surface of the high wall 201H.
[0035]
Thereby, since the inner peripheral surface of the high wall 201H protrudes inward from the outlet 232b of the intake portion 232, the outer peripheral rising wall 22c of the juice receiver 22 is inwardly protruded 201S even if the juice receiver 22 is displaced in the radial direction. The position Z is restricted so as not to approach the lower wall 201L, that is, the outlet 232b any more, and the gap Z can be secured. At this time, on the opposite side starting from the center of the juice receiving tray 22, the hanging wall 22 e of the juice receiving tray 22 and the inlet 232 a of the intake portion 232 approach each other. Y is secured. Therefore, even if the intake portion 232 approaches the inlet 232a of the intake portion 232 of the drooping wall 22e or the outlet 232b of the outer peripheral rising wall 22c due to the deviation of the juice receiving tray 22, an intake path can be secured without being blocked.
[0036]
The inward protrusion 201S is provided over the entire height of the high wall 201H. However, the inward protrusion 201S may be provided only on the upper part (the part of the convex part 201T) or the lower part (the part at the same position as the upper side part 200b1). . Further, if the outer peripheral rising wall 22c of the soup pan 22 is deep as indicated by an imaginary line, instead of providing the inner protrusion on the high wall 201H, the inner protrusion is a part of the side piece 200b3 below the high wall 201H. It may be provided only on the side piece 200b3 or from the side piece 200b3 to the lower piece 200b2.
[0037]
Another embodiment of the present invention is shown in FIG. In the drop-in stove 10 of the present embodiment, an internal flame type burner 39 accommodated in the stove main body 12 faces the opening 16 of the top plate 14 that covers the upper surface of the stove main body 12. Below the opening 39 a in the center of the burner 39, a juice receiving tray 34 is placed on an annular locking frame 33 attached to the burner 39.
[0038]
Above the burner 39, when the flame from the flame hole 39b flows upward from below the top plate 14, a collecting portion 38a that inclines upward toward the inside that guides the flame in the central direction, and a central portion by the collecting portion 38a. A guide member 38 having a diffusing portion 38b for guiding the flame guided to the outside upward is disposed. The base portion 38c of the guide member 38 is attached to the support 41 attached to the burner 39 with the gap 39 and the gap A between them, and air flows between the burner 39 and the guide member 38 to further reduce the flame. It leads to the center direction.
[0039]
The packing 20 is attached to the peripheral edge portion 14 a of the opening 16 of the top plate 14, an annular simmering ring 36 is placed on the packing 20, and the virtues 24 are placed on the top plate 14 outside the simmering ring 36. ing. The broth ring 36 covers the gap B between the diffusing portion 38b of the guide member 38 and the opening peripheral edge portion 14a of the top plate 14, and prevents the broth from falling from the gap B. The upper face portion 36a and the inner peripheral wall 36b and the outer peripheral hanging wall 36c, and the inner peripheral wall 36b is composed of an inclined portion 36b1 that is inclined downward toward the inner side and an inner peripheral hanging wall 36b2 that is suspended from the inner end thereof.
[0040]
Also in the present embodiment, the packing 20 attached to the opening peripheral edge portion 14 a of the top plate 14 is formed in the same shape as that of the first embodiment, and the horizontal portion 36 a of the broth ring 36 has a height higher than that of the packing 20. By being placed on the part wall 21H, the air intake part 32 is formed between the lower part surface of the lower part wall 21L of the packing 20 and the upper surface part 36a. At this time, the inner peripheral hanging wall 36b2 is located inside the diffusion portion 38b of the guide member 38. When the soup receiving cover 36 is placed on the packing 20, the lower end of the outer peripheral hanging wall 36 c has the top plate upper surface and the gap X as in the previous example.
[0041]
Therefore, sufficient combustion air can be supplied into the stove body 12 even when the combustion air is sucked from above the top plate 14 from the intake portion 32 and the stove body 12 has high sealing performance. Moreover, since the intake part 32 is formed between the upper surface part 36a of the broth ring 36 only by providing the convex part 21T of the packing 20 at intervals, the intake structure is also simple.
[0042]
Further, the outward projecting portion 21S on the outer surface of the high wall 21H of the packing 20 and the cutout portion 20cS on the inner side of the low wall 21L are the same as those in the previous embodiment, and have the same effects. In this example, the top plate 14 includes a glass plate 141 and a frame 142 on the outer periphery thereof.
[0043]
The same applies when the packing 200 according to the second embodiment is used instead of the packing 20.
[0044]
FIG. 7 shows an embodiment in which the broth ring 360 is employed in an external flame type gas burner 40. The gas burner 40 includes a burner body 401 and a burner head 402.
[0045]
The broth ring 360 includes a central opening 360b, an upper surface portion 360a around the center opening 360b, and an outer peripheral hanging wall 360c depending from the outer peripheral edge of the upper surface portion 360a. The upper surface portion 360a covers the gap Z between the outer surface of the burner 40 and the packing 500 of the top plate 14, and is inclined downward toward the outside, so that the simmered juice falling on the upper surface portion 360a is directed to the top plate 14 side. As a result, the boiled juice does not fall into the stove body from the gap Z between the burner 40 and the packing 500.
[0046]
The packing 500 in the present embodiment has the same basic structure as the packing 20, the upper surface portion 360 a of the broth ring 360 is placed on the high wall 501 </ b> H, and the lower surface portion and the upper surface portion 360 a of the low wall 501 </ b> L. A gap is formed between the two and the intake portion 532 is formed.
[0047]
Since the gas burner 40 is inserted into the central opening 360b of the simmered ring 360 and placed on the high wall 501H, the radial movement of the simmered ring 360 is limited by the gas burner 40, so that the deviation hardly occurs. Unlike the packings 20 and 200, there are no outward or inward positioning protrusions.
[0048]
When the broth ring 360 is placed on the high wall 501H, the gap X between the outer peripheral hanging wall 360c and the top plate 14 and the gap Y between the outer peripheral hanging wall 360c and the inlet 532a of the intake section 532 are It exists in the same way as the previous embodiment.
[0049]
As described above, when the burner 40 is burned, the combustion air is sucked from the primary air port of the burner 40 through the gaps X and Y and the intake portions 532 and Z.
[0050]
In each of the above embodiments, a drop-in stove using a top plate made of only a glass plate or made of a glass plate and an outer peripheral frame has been described as an example. However, the top plate has a number of thicknesses instead of a glass plate. It is also possible to employ a metal plate such as mm aluminum or a top plate in which the periphery of a thin metal plate is bent.
[0051]
【The invention's effect】
As apparent from the above description, according to the stove of the present invention, by providing a convex portion with an interval in the circumferential direction on the upper surface of the packing attached to the opening peripheral portion of the top plate covering the upper surface of the stove body, Since the intake part is defined between the soup pan or boiled ring placed on the packing and the packing, even if the stove main body is highly sealed, sufficient combustion air can be sucked and supplied into the stove main body, Its intake structure is also simple.
