DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on the illustrated embodiments. FIG. 1 is a schematic perspective view showing a gas stove according to an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view showing a main part of the gas stove according to an embodiment of the present invention. In the present embodiment, the present invention is applied to a drop-in stove suspended from an opening provided on a worktop such as a system kitchen.
[0015]
As shown in these drawings, the stove body 2 of the gas stove (drop-in stove) 1 according to the present embodiment is suspended by the flange portion 21 around the opening periphery of the countertop K, and the top opening is formed by the top plate 3. Covered. The top plate 3 is composed of a metal frame 31 such as aluminum and a ceramic glass plate 32. In the present embodiment, the ceramic glass plate 32 is formed with circular openings 3a facing gas burners 4 described later at two locations.
[0016]
Below each opening 3 a of the top plate 3, an annular internal flame type gas burner 4 with a plurality of flame holes 4 a directed toward the center is installed on the stove body 2 via a support member 22. Below the inside is a spilled saucer 5. An ignition knob 6 for the gas burner 4 is provided on the top surface of the top plate 3.
[0017]
Above the gas burner 4 installed in the stove body 2, a cylindrical guide member 8 having a base 8 c screwed to a support member 7 attached to the gas burner 4, and a thermocouple 9 for detecting misfire of the gas burner 4. Is installed. The guide member 8 is provided with a guide portion 8a which is inclined corresponding to the direction of the flame coming out of the flame hole 4a of the gas burner 4 and is inclined upward toward the inside for guiding the flame in the central direction. And in the vicinity of the opening 3a above the guide portion 8a, it faces vertically upward, and the tip portion 8b is bent toward the opening edge 3b side of the top plate 3 to form an enlarged portion, and the flame is placed outside the opening 3a. Guided.
[0018]
Further, since the flow path T is formed between the base 8c of the guide member 8 and the gas burner 4, the combustion air flows in the direction of the arrow, so that the flame of the gas burner 4 is directed inward without immediately rising. Can be guided.
[0019]
The distal end portion 8b of the guide member 8 is located substantially on the same plane as the opening portion 3a, and a gap G of about several mm is provided between the distal end portion 8b of the guide member 8 and the opening edge portion 3b of the top plate 3. ing. The guide member 8 is screwed to the support member 7 at its base portion 8c. Since the support member 7 is attached to the gas burner 4, the gas burner 4 and the guide member 8 are interposed via the support member 7. And the correlation position between the two is maintained. A protective member 10 that protects the opening edge 3b is fixed to the opening edge 3b of the top plate 3.
[0020]
The five virtues 11 placed around the opening edge 3b of the top plate 3 are composed of six five virtue claws 11a and five virtue frames 11b connecting the five virtue claws 11a. A ridge ring portion 11c as a positioning portion is formed on the back surface of the virtuosity frame 11b. The ridge ring portion 11c is formed in the gap G when the virtues 11 are seated on the upper surface of the ceramic glass plate 32 of the top plate 3. The outer periphery 11d of the protrusion ring portion 11c faces the tip portion 8b of the guide member 8 with a slight gap of about 1 mm.
[0021]
As a result, the virtues 11 are positioned at the tip 8b of the guide member 8, and as a result, the virtues 11 can maintain a good relative relationship with the gas burner 4. Even if a gap occurs between the top plate 3 and the stove main body 2 like the drop-in type gas stove in the present embodiment in which the top plate 3 is placed on the countertop K, the five virtues 11 Since the gas burner 4 and the gas burner 4 can maintain a good relative relationship, the flame of the gas burner 4 does not touch the misaligned virtues 11 as in the prior art.
[0022]
Further, the five virtue frame 11b of the five virtues 11 includes a collar part 11e so as to project inward from the base part of the ridge ring part 11c and covers the tip part 8b of the guide member 8 with the collar part 11e. The virtue frame 11b has an outer peripheral edge located outside the opening edge 3b, and the inner peripheral edge, that is, the collar portion 11e covers the tip 8b, so that even if the boiled juice produced during cooking falls to the gort frame 11b. It does not fall into the gap G.
[0023]
Further, in the present embodiment, the flange portion 11e covers the distal end portion 8b of the guide member 8, and the distal end portion 8b of the guide member 8 is prevented from being exposed to flame without projecting inward as much as possible. Is enlarged by being bent outward, and the tip of the flange portion 11e is positioned above the enlarged portion.
[0024]
As described above, the virtues 11 are placed and positioned around the opening edge portion 3b of the top plate 3, so that the rattling of the virtues 11 is small and stable. In addition, the positional relationship between the virtues 11 and the gas burner 4 is also maintained well.
[0025]
Further, when the above-mentioned virtues 11 are placed around the opening edge 3b of the top plate 3, the leg portions 12 provided on the lower surface of the virtuosity frame 11b are seated on the top surface of the top plate 3, thereby There is a gap between the top plate 3 and the top surface of the top plate 3, and a flow path is formed through which air flows. Thus, air can be supplied from the periphery of the virtues 11 to the periphery of the gas burner 4 in the stove body 2 through this flow path.
[0026]
In the embodiment described above, the gas stove has the top plate 3 made of a metal frame and a ceramic glass plate. However, the present invention is similarly applied to a gas stove having a top plate made of metal such as aluminum or stainless steel. Can do.
[0027]
Further, in the above-described embodiment, the virtues 11 are integrally cast with the virtues 11 having the claws and the protruding ring portions (positioning portions) on the back surface. The positioning part may be attached to the rear surface of the five virtue frame by welding or the like.
[0028]
