Problems solved by technology

[0004] However, in a gas range equipped with the guard ring 100, if the guard ring 100 is touched when cleaning the vicinity of the burner opening 102, the guard ring 100 is likely to rotate.
Once the protection ring 100 rotates, it may scratch the glass cover plate 101, and it is also easy to wear the sealing gasket 113
In addition, even if the trivet metal frame mounted on the opening edge of the burner opening 102 is fastened to the protection ring 100 to prevent the rotation of the trivet metal frame, the rotation of the protection ring 100 may cause the trigone metal frame to be unable to be determined. The problem with the position of the metal frame

no. 1 Embodiment approach

[0038] Next, a first embodiment of a gas range embodying the present invention will be described with reference to FIGS. 1 to 10 . In the drawings, "ON / OFF" means "on / off".

[0039] As shown in FIGS. 1 and 2 , the main body case 21 as the main body of the gas range 20 is a box-shaped body with an opening on the upper surface. A flange 21 a is formed on the outer edge of the upper end of the main body case 21 . The top opening 21b of the main body case 21 is covered by a glass cover 22 made of heat-resistant glass. At the rear of the glass cover 22, a pair of burner openings 22a are formed, and a cap-shaped The frame 22b. Although this glass cover plate 22 has translucency, it is colored (dark), so that people cannot see the situation in the main body box 21 clearly. And, the main body box 21 is inserted in the installation hole 23a formed on the stove top 23 of the kitchen, and the flange 21a of the main body box 21 is supported on the stove top 23, forming a so-called susp...

no. 2 Embodiment approach

[0061] Next, a second embodiment of a gas range embodying the present invention will be described with reference to FIG. 11 . In the second embodiment, on the basis of the first embodiment, the configurations of the lower ring and the mounting bracket are changed. In the following description, the same parts as those of the first embodiment are denoted by the same reference numerals and their descriptions are omitted.

[0062] As shown in FIG. 11( a ), on the extended portion 67 of the lower ring 66 is formed a protrusion 68 extending in the direction of its extension. The protrusion 68 functions as a structure for increasing the strength of the extension 67, and when the guard ring 50 is attached to the burner opening 22a, the extension 67 is prevented from sagging due to its own weight.

[0063] And as shown in Fig. 11 (b), (c), a concave portion 35a is formed at the rear corner of the mounting frame 35, and the engaging portion 64 is engaged with the concave portion 35a to...

no. 3 Embodiment approach

[0067] Next, a third embodiment of a gas range embodying the present invention will be described with reference to FIG. 12 . In the third embodiment, the configuration of the lower ring is changed on the basis of the first embodiment.

[0068] On the outer edge of the lower flange 57 of the lower ring 71 are formed two extensions 72A, 72B extending in the radial direction thereof, and the ends of the two extensions 72A, 72B form a buckling portion 73 . The extension 72A and the extension 72B are parallel to each other. And between the end of the extension 72A and the end of the extension 72B, the snap-fit ​​is made in a slightly wider state (state shown by a solid line in FIG. The extensions 72A, 72B can be snapped onto the mounting frame 35 by pinching the rear corners of the mounting frame 35 by the portion 73 .

[0069] This embodiment has the following effects in addition to the same effects as (1) to (4) of the first embodiment.

[0070] (6) The extensions 72A, 72B pin...

Abstract

The present invention provides a gas cooking stove that overcomes drawbacks caused by rotation of a protective ring. The gas cooking stove comprises a fitting frame for accommodating a switch board provided on a lower surface of a glass top plate, and a protective ring composed of an upper ring member and a lower ring member and fitted to a burner opening formed in the glass top plate. An extension portion extends from the lower ring member to the fitting frame, and the extension portion is secured to the fitting frame to prevent rotation of the protective ring.

Description

technical field [0001] The present invention relates to a gas range, and more specifically, to a gas range having a glass cover and a guard ring attached to an opening for a burner formed on the glass cover. Background technique [0002] Existing this kind of gas cooker is all installed protective ring on the burner opening that forms on the glass cover plate. For example, a guard ring 100 disclosed in JP-A-10-318545 is attached to an inner edge of a burner opening 102 formed in a cover glass 101 as shown in FIGS. 18( a ) and ( b ). The edge of the opening 102 for the burner is relatively fragile. For example, when a trivet metal frame etc. hits the edge of the opening 102 for the burner, the edge of the opening 102 for the burner is easy to be damaged, so the edge of the opening 102 for the burner is protected with a protective ring 100 . [0003] The protection ring 100 is composed of an upper ring 104 including an inner cylinder portion 106 and an upper flange portion 1...
