Description

[Detailed Description of the Invention] The present invention relates to a device for attaching parent and child burners, and is particularly intended to prevent forgetting to attach child burners.

In the parent and child burners used in general gas staples, the child burners are mainly fixed to the parent burner, or each child burner is fixed independently, so even if the child burners are not attached to the appliance body, only the parent burner can be used. Although it is attached to the main body of the appliance, the child burner is relatively inconspicuous. (If you forget to attach the child burner when setting it up after cleaning, and you turn on the ignition without noticing, the child burner nozzle spews out raw gas.) There was a risk that this ejected gas could ignite and cause an explosion.

The present invention has been devised to improve the above-mentioned points, and embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a so-called general gas staple with a grill, in which a gas stove 3.4 is provided on the left and right sides of the upper surface of the main body 2, and a grill 6 whose front surface is opened and closed by a door 5 is provided between the stoves.

7 is a so-called parent-child burner attached to the stove 3 on the left,
A secondary burner 9 made by bending a steel pipe into an oval shape and having a burner head 8 attached to the upper end, a gas inlet 10 at the base end, and a cast mixing pipe with an annular opening 11 in the head part. 11, a burner cap 12 is removably attached to the opening 11 of the mixing tube, and a main burner 14 is formed with a main flame hole 13 by this attachment.

Note that 21 is an air hole formed in the center of the annular master burner 14, through which the slave burner 9 is inserted.

Reference numeral 15 designates a first fitting projection that projects downwardly from the bottom surface of the head portion of the main burner 14, and legs 16 and 16' project from both sides of the first fitting projection 15.

Reference numeral 17 denotes a support plate for the parent and child burner I, which has one end fixed to the upper surface of the side plate 18 of the main body 2 and the other end fixed to the wall of the grille 6 chamber (not shown), and has a pair of slit-shaped parts with a smaller diameter than the first fitting protrusion 15. The second fitting holes 19 and 19 are arranged in parallel.

Reference numeral 20 denotes a supporting metal fitting having a substantially inverted shape, and its outer surface 21 is fixed to a proper vertical part of the child burner 9, and the first fitting protrusion 15 of the main burner 14 is fitted into the horizontal surface 22. A first fitting hole 23 is bored therein, and the second fitting hole 19,1 is formed from two sides surrounding the extension side of the vertical surface 21 of the horizontal surface 22.
Second fitting protrusions 24 and 24 are provided vertically to fit into the respective holes.

In addition, in the above structure, when the legs 16 and 16' of the main burner 14 are placed on the support fitting 20, the legs 1
6.16' is configured to be shorter than the first fitting protrusion 15 (see Fig. 4), and when the legs 16 and 16' are placed on the support plate 17, the legs 16 and 16' are made shorter than the first fitting protrusion 15 (see Fig. 4). It is sufficient if the length is longer than 15 (see FIG. 5).

Further, the support metal fitting 20 may be screwed to the support plate 17, and in that case, the positioning of both may be performed using another structure.

When installing the parent and child burner 7, first fit the base end of the child burner 9 to the child nozzle 25, and then attach the support fitting 20.
is supported and fixed to the support plate 17 by inserting the second fitting protrusions 24, 24 into the second fitting holes 19, 19.

Next, after fitting the gas suction hole 10 at the base end of the main burner 14 to the main nozzle 26, the child burner 9 is inserted into the central air hole 27.
If the first fitting protrusion 15 provided at the tip is fitted into the first fitting hole 23 of the support metal fitting 20, it will be securely fixed.

These legs 16 and 16' are the support plate 17 or the support metal fittings 20.
The main burner 14 is placed stably in a horizontal state.

In addition, when installing the parent burner 7, if the parent burner 14 is installed without the child burner 9 installed, the diameter of the first fitting protrusion 15 of the parent burner 14 in the embodiment shown in FIG. Since the diameter of the second fitting holes 19, 19 of the support plate 1T is larger, the first fitting protrusion 15 is larger than the diameter of the second fitting holes 19, 19.
and in the case of the embodiment of FIG.
' comes into contact with the support fitting 20 and the first fitting protrusion 15 is in a state floating from the support fitting 20.
In either case, the head portion of the main burner 14 is not stably supported when the burner 14 is fitted into the fitting holes 19, 19, and the user realizes that the child burner 9 has been forgotten to be attached.

As described above, the parent-child burner mounting device according to the present invention has a burner head of a child burner disposed in the center hole of a parent burner having an annular burner head, and a supporting metal fitting that fixes the child burner to the child burner. The main burner is supported on a support plate provided on the main body of the apparatus, and the main burner is supported on the support plate via the support metal fitting, and the main burner and the support metal fitting are provided with first fitting means that can be fitted to each other. The support fitting and the support plate are provided with second fitting means that can be fitted to each other, and the first fitting means of the parent burner and the second fitting means of the support plate are formed so that they cannot fit together. Therefore, unless the child burner is supported by the device body, the parent burner cannot be attached to a predetermined position on the device body, and it is possible to prevent forgetting to attach the child burner.
