Description

  The present invention relates to a stove equipped with an internal flame type burner, and prevents the broth spilled from the pan from falling into the stove case from the central hole of the internal flame type burner.

FIG. 5 is a cross-sectional view of a burner arrangement portion of a conventional stove (see FIG. 2 of Patent Document 1).
Below the flame guide (6) arranged concentrically with the burner opening (52a) opened on the stove top (52), a burner body (22 ) Is provided with an internal flame burner (2).
Below the burner body (22), there is provided a juice tray (32) and a tray support frame (30) for mounting the juice tray (32) in a lowered state. The outer diameter of the dish support frame (30) is set to be slightly smaller than the inner diameter of the lower end of the burner body (22), so that the gap between the outer periphery of the dish support frame (30) and the burner body (22) is reduced. It functions as a secondary air port (A), and secondary air for combustion is supplied from the secondary air port (A) to the flame hole (21).
Also, on the stove top plate (52), the five virtues (4) comprising the five virtue frames (41) along the periphery of the burner opening (52a) and the five virtue claws (42) formed integrally therewith are placed. At the same time, the inner peripheral edge of the five virtue frame (41) protrudes to the inside of the tapered cylindrical flame guide (6).

In this case, when the internal flame burner (2) is burned, the secondary air port (A) on the outer periphery of the pan support frame (30) that supports the soup pan (32) is moved to the inner periphery of the burner body (22). Combustion secondary air is supplied and burner combustion continues, whereby the pan (9) on the virtues (4) is heated. Accordingly, in this case, the combination of the soup pan (32) and the tray support frame (30) functions as a secondary air guide for guiding the secondary air to the gas combustion section.
On the other hand, when boiling is spilled from the pan (9) during cooking, this is a soup saucer from the inner peripheral end of the Gotoku frame (41) that functions as a boiling juice cover over the flame hole (21) on the inner periphery of the burner body (22) (32) Drops on. Therefore, the broth does not adhere to the flame hole (21) on the inner periphery of the burner body (22) and cause poor combustion, and the broth falls into the stove case below the internal flame burner (2). It becomes difficult to do.
JP 2004-232297 A

However, in the above-mentioned conventional one, the secondary air port (A) below the internal flame type burner (2) is in a position where it can be directly viewed from the cooking work position above the stove through the central hole of Gotoku (4), There is a possibility that the boiled soup or the like blown from the pan (9) jumps linearly and obliquely into the secondary air port (A) and contaminates the stove case (51).
In addition, when the pan (9) is lowered from the virtues (4), the secondary air port (A) along the inner peripheral lower end of the internal flame burner (2) can be exposed from above the virtues (4). There has been a problem of harming the sense of design.

The present invention has been made in view of such points.

It is an object to prevent the contamination in (51) and to improve the design feeling by preventing the secondary air port from being exposed from above the stove.

[Invention of Claim 1]
The technical means of the invention according to claim 1 for solving the above-mentioned problem is as follows:
`` A cover ring that protrudes inward from the upper area on the outer peripheral side of the burner body (22) and covers the flame hole (21) formation area on the inner periphery of the burner body (22) in plan view;
That is, the secondary air port is located outside the tangent line that is in contact with the upper part of the inner periphery of the cover ring and the lower end of the inner periphery of the burner body (22).
According to the above technical means, since the cover ring squeezed inward from the outer peripheral side of the burner body (22) is provided, the boiled broth spilled from the pan is the flame hole (in the inner periphery of the burner body (22) ( 21) It does not fall and burner combustion is not hindered.
On the other hand, a secondary air port outside the tangent line that touches the upper inner peripheral edge of the cover ring and the inner peripheral lower end of the burner body (22) (opening for supplying combustion secondary air to the flame hole (21) from below) Is provided. Therefore, the secondary air port is located outside the intersection of the tangent and the secondary air guide. Therefore, the points where the broth spilled from the pan directly hits the secondary air guide are all inside the intersection, and the broth jumps into the secondary air port and the stove case (51) below the internal flame burner (2) No contamination inside.
Further, since the secondary air port is located outside the tangent line, the secondary air port is hidden by the burner body (22) and cannot be exposed from the cooking work position, and the design feeling is improved.

[Invention of Claim 2]
In the invention according to claim 1,
`` The cover ring is a five virtue frame (41) of the five virtues (4) arranged in a manner covering the periphery of the burner opening (52a) of the stove top plate (52) from above.

The periphery of the burner opening (52a) opened on the stove top (52) is covered with a protective cover (55) consisting of an annular upper frame (55a) and lower frame (55b) fitted vertically. Thus, damage to the peripheral edge of the burner opening (52a) established in the glass stove top (52) is prevented.

[Gotoku (4)]
Gotoku (4) placed at the position facing the burner opening (52a) on the stove top (52) is along the upper surface of the virtuosity frame (41) that covers the periphery of the burner opening (52a) from above. And a plurality of five virtue claws (42) provided at a predetermined pitch in the circumferential direction.
The virtuosity frame (41) is an annular flat plate drawn with a press, an outer peripheral plate (411) placed on the upper surface of the stove top plate (52), and an upper surface plate (412) bent inward from the upper end thereof And a gently tapered inner peripheral inclined plate (413) that decreases from the inner periphery toward the inner side, and an inner peripheral suspension plate (414) that bends and hangs from the inner periphery. The five-virtual frame (41) protrudes inward from the outer peripheral side of a burner body (22) described later in plan view, and the inner peripheral edge of the five-virtual frame (41) is the inner peripheral edge of the burner body (22). The flame hole (21) formation area is covered in plan view. Therefore, in the present embodiment, the five virtue frames (41) correspond to the covering according to claim 1.
In addition, the upper plate (412) of the virtuosity frame (41) is provided with a caulking hole (44) for inserting and crimping a fitting projection (420) projecting downward from the virtuosity claw (42), A positioning leg (421) depending from the five virtue claws (42) passes through the inner peripheral inclined plate (413). The lower end of the positioning leg (421) is fitted into an inwardly opened cutout (56) formed in the protective cover (55) of the burner opening (52a) of the stovetop (52) described above. The five virtues (4) are positioned in the circumferential direction by the insertion.

[Fire guide (6)]
Below the virtuosity frame (41) is provided a tapered cylindrical flame guide (6) whose diameter increases downward, and the upper end of the flame guide (6) is the inner circumference of the virtuosity frame (41). Located outside the drooping plate (414). Further, the gap between the lower surface of the flame guide (6) and the upper surface of the burner body (22) is burned from the upper secondary air port (20a) formed at the outermost peripheral end of the gap to the upper side of the flame hole (21). It serves as a secondary air passage (20) for supplying secondary air for use.

[Inner flame type burner (2)]
The internal flame burner (2) provided below the flame guide (6) is a caulking connection between the upper half (24) and the lower half (25) formed by drawing a metal plate. Gas is supplied to the annular burner body (22) from a mixing tube (not shown). The burner body (22), the flame guide (6), the five virtue frame (41) and the burner opening (52a) are all arranged concentrically.

[Secondary air guide (31)]
The secondary air guide (31) facing the central hole (220) of the burner body (22) from below is formed in a tapered shape that decreases from the outer periphery toward the central side, and in a plan view, the burner body (22 It is formed in a disk shape that is one size larger than. As a result, the boiled juice dripping from the upper surface of the burner body (22) along the outer peripheral edge (26) flows from the pan during cooking toward the center on the secondary air guide (31). The juice is collected in the juice tray (32) mounted in the central recess (311). Further, a peripheral upright portion (33) is bent and erected on the outer periphery of the secondary air guide (31) to prevent leakage of the broth.

  Also, the burner body (22) and the secondary air guide (31) are arranged above and below with a gap serving as a secondary air passage (23), and the outermost peripheral side of the secondary air passage (23). A gap between the peripheral standing part (33) and the burner body (22) is a lower secondary air port (230) (corresponding to the “secondary air port” which is the above-described invention specifying means). Note that the height of the instrument increases as the vertical dimension of the secondary air passage (23) increases.Therefore, it is necessary to reduce the vertical dimension to meet the demand for a compact instrument, but the secondary air guide (31) However, if it is too close to the burner body (22), the broth adhering to the secondary air guide (31) is heated by the flame and sticks to the secondary air guide (31). Accordingly, the vertical dimension of the secondary air passage (23) is set to a predetermined size or more so as to prevent sticking while taking the compactness into consideration.

  As described above, the secondary air guide (31) has a plane shape that is slightly larger than the burner body (22), but the inner peripheral inclined plate (413) of the virtually frame (41) and the inner peripheral drooping The lower secondary air port (230) is located outside the tangent line (S) contacting the bent boundary point (415) of the plate (414) and the inner peripheral lower end (27) of the burner body (22). That is, the lower secondary air port (230) is located outside the intersection (P) between the tangent line (S) and the secondary air guide (31). Therefore, the points where the broth spilled from the pan to be heated directly hit the secondary air guide (31) are all inside the intersection (P), and the broth jumps into the lower secondary air port (230). The inside of the stove case (51) below the internal flame burner (2) is not contaminated.

Further, since the lower secondary air port (230) is located outside the tangent (S), the secondary air guide extends from above the drop-in stove (5) through the central hole of the virtually frame (41). When (31) is viewed, the lower secondary air port (230) is hidden by the burner body (22) and cannot be exposed from the cooking work position, and the design feeling is improved.
In the present embodiment, the broth spilled from the pan is burner body (22) from the inner periphery of the five virtue frame (41) protruding inward from the inner periphery of the burner body (22) in plan view. Since it falls into the central hole (220), the broth does not adhere to the flame hole (21). Therefore, in the present embodiment, the five virtue frames (41) have a function as a soup cover that prevents the soup from adhering to the flame hole (21). Therefore, the number of parts can be reduced as compared with the case where an independent broth cover is provided.

[Juice tray (32)]
The engagement flange (321) protruding from the upper outer periphery of the juice receiving tray (32) dropped into the recess (311) formed in the center of the secondary air guide (31) is the recess of the secondary air guide (31) ( 311) is engaged with an engagement step portion (312) formed on the outer periphery of the upper end, and a knob piece (322) is projected upward from a part of the engagement flange (321). By picking (322) and removing the soup pan (32), the boiled juice stored in the soup pan (32) can be removed and washed.

<< Second Embodiment >>
In the first embodiment, the gap between the outer peripheral edge of the secondary air guide (31) and the burner body (22) is the lower secondary air port (230). However, the second embodiment shown in FIG. As in the embodiment, the through hole (31a) may be provided through the plate thickness portion in the vicinity of the outer periphery of the secondary air guide (31). In this case, the gap between the burner body (22) side edge of the through hole (31a) and the burner body (22) becomes the lower secondary air port (230).
This includes the lower secondary air port (230) and the tangent (S) that touches the bent boundary point (415) of the virtuosity frame (41) and the inner peripheral lower end (27) of the burner body (22). Adjacent through holes (31a) are formed. This prevents the broth spilled from the pan on the virtues (4) from jumping linearly into the lower secondary air port (230) or the through hole (31a), as in the embodiment described above. The broth does not enter the stove case (51) below the internal flame burner (2) and contaminate it. Further, when the secondary air guide (31) is viewed from above the drop-in stove (5) through the central hole of the virtuosity frame (41), the lower secondary air port (230) and the through hole (31a) are The design feel is improved because the cover is hidden by the burner body (22).

<< Third Embodiment >>
