BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas stove, and more particularly to a gas stove burner equipped with a heat sensitive body for detecting the temperature of a cooking container, which is provided with a heat shield tube provided to prevent malfunction of the heat sensitive body. The present invention relates to a gas stove with an improved mounting structure.

[0002]

2. Description of the Related Art A gas stove using a burner cap that also serves as a heat shield is proposed by the applicant of the present invention and disclosed in Japanese Utility Model Laid-Open No. 2-77502. Is shown in FIG. In this structure, a burner is formed by the burner main body 1 and the burner head 2 covered with the burner main body 1, and a function as a heat shield cylinder for protecting the heat sensitive body 4 and a cover for preventing the infusion of juice is given to the upper side of the burner head 2. The burner cap 3 described above is applied.
In this configuration, the burner cap 3 is only placed on the burner head 2.

The one shown in FIG. 7 is disclosed in Japanese Utility Model Laid-Open No. 59-188014 previously proposed by the present applicant. According to this gas stove, the heat shield cylinder 5 for protecting the heat sensitive body 4 is placed on the burner head 2 forming the burner via the spacer 5a formed to secure the gap G1 and the heat shield is provided. A gap G2 is maintained between the cylinder 5 and the bottom plate of the cooking container 6 to allow air to flow therethrough, thereby preventing abnormal overheating of the heat sensitive body 4.

[0004]

[Problems to be Solved by the Invention] In the above-described gas stove, since the burner cap 3 or the heat shield cylinder 5 is placed on the burner head 2, such as a heavy pot containing a large amount of contents. When the cooking container 6 is placed on the Gotoku 7, the top plate T of the stove is bent, and the Gotoku 7 placed on the plate T sinks together with the top plate T, so that the heat shield cylinder 5 and the bottom of the cooking container 6 are separated from each other. As they approach each other, it becomes difficult to secure the gap G2. Therefore, there is a problem in that heat is trapped inside the shield cylinder 5, which causes the heat sensitive body 4 to malfunction.

Therefore, an object of the present invention is to provide a gas stove in which a heat shield tube is always properly attached to a burner head and a proper gap G ₂ is always secured to prevent malfunction of a heat sensitive body. To do.

[0006]

In order to achieve the above object, the present invention provides a gas burner arranged at the center of the opening of a top plate and a heat shield tube arranged at the upper center of the gas burner. In a gas stove equipped with a heat sensitive body that is surrounded by this heat shield and protrudes upward, and a Gokutoku that is mounted on the top plate with a plurality of Gokutoku claws that are arranged radially around the gas burner, The heat shield tube is characterized in that the heat shield tube is attached to the inner end of the Gokutoku nail with a sufficient level difference between the upper side of the nail and the upper end of the heat shield tube.

[0007]

The gas stove of the present invention is constructed by attaching a heat shield tube to the inner end of the Gotoku claw forming the Gotoku, so that even if the cooking stove top plate is bent by a heavy cooking container The distance between the cooking containers does not change, the amount of air passing through the heat shield cylinder and the cooling action of this air on the heat sensitive body are substantially constant, and malfunction of the heat sensitive body is prevented.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A first embodiment of the present invention will now be described with reference to FIG.
5 through FIG. In these drawings, reference numeral 11 indicates a top plate that constitutes the upper surface of the gas stove, and inside the opening at the center of the top plate 11, a burner body 12a and a burner head 12b are formed, and a flame port 12c. A gas burner unit 12 having a heat sensitive body 13 is arranged in the upper center part of the burner unit 12, and the heat sensitive body 13 is always pushed upward by a spring 13c. It was housed in one.

The hole 1 through which the heat sensitive body 13 can project
The heat shield cylinder 14 having 4a at the center is the burner unit 1
It is attached to the Gotoku 15 with a gap G1 which serves as a secondary air passage to the flame opening portion 12c of No.2. This heat shield 14
Has a cylindrical portion 14b formed by pressing around the hole 14a in the central portion, and the cylindrical portion 14b and the cylindrical body 1 are
A gap G3 through which cold air can pass is formed between 3b, a flat portion 14c extends radially from the lower end of the tubular portion 14b, and a downward-facing large-diameter tubular portion 14d is continuously provided.
Here, the cylindrical portions 14b and 14d mainly act as a heat shield portion for the heat sensitive body 13, and the flat portion 14c mainly acts as a broth intrusion prevention cover.

Gotoku 15 is a plurality of Gotoku nails 15a and 15b.
Is attached to the outer frame 15c by caulking the projection 15d. The Gotoku claws 15a and 15b are arranged alternately, and the Gotoku claw 15a has a protrusion 15e on the lower side of the tip portion, and the protrusion 15e is the flat portion 14c of the heat shield cylinder 14.
The Gokutoku nail 15a and the heat shield cylinder 14 are integrated by being fitted into a hole opened in the front and crimped. Further, a pair of protrusions 15d on one diameter line is provided with a positioning protrusion 15f that is fitted into a hole provided in the top plate 11. A sufficient air gap G ₂ is provided between the upper side of the Gotoku 15 and the upper end of the tube portion 14b.
Is provided with a step h. It should be noted that the Gotoku nail 15b may also be provided with a projection 15e to have the same structure as the Gotoku nail 15a, and the projection 15e may be simply inserted into the hole formed in the flat portion 14b or caulked after the insertion.

In the above embodiment, the Gotoku claw 15a and the heat shield tube 14 which also functions as a broth intrusion prevention cover are integrated, but in the second embodiment shown in FIG. 3, the Gotoku claw 15a is formed. This is an example in which the inner end portion 15g is fitted and integrated with a heat sensitive tube 16 provided only for protecting the heat sensitive body 13 from heat. The spacer 1 is provided near the lower end of the heat shield tube 16.
A separate broth intrusion prevention cover 18 supported by 7 is arranged.

In the third embodiment shown in FIG. 4, a flange 16a is formed on the upper end of the heat shield cylinder 16 so as to extend over the entire circumference in the diametrical direction.
It is placed on the step portion 15h formed in 15b,
The flange 16a also serves as a cover for preventing the infusion of broth.

In the fourth embodiment of FIG. 5, the flange 16a of the embodiment shown in FIG. 4 has a smaller diameter, and a projecting edge 16b is formed at the upper end of the heat shield. 1
It is placed on the step portion 15i formed in 5a and 15b, and is provided with a broth intrusion prevention cover 18 supported by the spacer 17 as in FIG.

In this way, the Gotokuzume 1 provided on the gas stove
Since the heat shield cylinder 14 or 16 is provided on the 5a, it is ensured that the gap G ₂ due to the step h is constantly maintained on the lower side of the cooking container 6. In addition, in the first and second embodiments, since the Gotoku 15 and the heat shield tubes 14 and 16 are integrated by caulking or the like, these parts are turned upside down or diagonally when assembled or disassembled for cleaning. By attaching the heat sensitive body 4 to the heat sensitive body 4, the characteristics of the heat sensitive body 4 do not change and malfunction does not occur.

[0015]

[Effects of the Invention] As is apparent from the above description, according to the present invention, the heat sensitive body provided above the center of the burner is surrounded by the five virtue on the top plate of the gas stove to keep a certain gap. Since the heating cylinder is attached, even if a heavy cooking container is placed, it is possible to reliably maintain a gap through which cold air can pass and prevent abnormal overheating of the heat sensitive body. This has the effect of reliably preventing malfunctions.
