Japanese Unexamined Patent Publication No. 2016-88539 Japanese Unexamined Patent Publication No. 2005-247332

In the above-mentioned conventional packing structure, a burner venturi (mixing pipe) is fixed to the burner mounting plate of the stove body, but there is no receiver above the burner venturi and it is open to the space. Therefore, when the outer box containing the stove body is dropped from the top surface side, the load applied to the burner venturi cannot be received due to the impact when the top surface is dropped. In this case, when the load is applied to the burner venturi, the burner venturi moves by inertia, and the burner mounting plate for fixing the burner venturi may be lifted to deform the burner mounting plate or the stove body for fixing the burner mounting plate. In particular, when the burner venturi is heavy such as made of a casting, a large load is applied to the burner venturi due to the above-mentioned top drop, and the burner mounting plate or the stove body is likely to be deformed. If the burner mounting plate or the like is deformed in this way, the position of the burner venturi on the stove body will shift, and therefore the correlation of the parts attached to the gas burner (for example, ignition electrode, TC, trivet, etc.) will also shift. There is a risk that the gas burner and its surrounding parts will not function normally.

The present invention has been made in view of the above circumstances, and provides a burner holding member for holding a burner venturi so that the burner venturi does not shift when the outer box containing the stove body is dropped on the top surface. The purpose.

The burner holding member according to the present invention is
A burner holding member for holding the burner venturi fixed to the burner mounting plate of the stove body against the stove body of the gas stove that is stored in the outer box with a space between it and the top surface of the outer box. There,
It is provided with a shock absorbing portion that is supported on the cylindrical burner venturi top of the burner venturi and is arranged so as to be in contact with the top surface of the outer box.
As a result, when the outer box containing the stove body (hereinafter referred to as the packed product) is dropped on the top surface, the impact absorbing part receives the impact of the burner venturi when the top surface is dropped, and the load applied to the burner venturi is applied. Take it. Therefore, it is possible to prevent the burner venturi from moving due to inertia and deforming the burner mounting plate or the stove body.

In the burner holding member
The flange that comes into contact with the top edge of the burner venturi top,
A support part formed at the bottom of the flange part and inserted into the burner venturi top,
It can be configured to have a spacer portion formed on the upper portion of the flange portion and serving as the shock absorbing portion.
With this configuration, the burner holding member can be stably supported on the burner venturi top by the support portion. The flange portion determines the mounting position of the burner holding member with respect to the burner venturi top, and the spacer portion is arranged at a predetermined height position on the burner venturi top so as to be interposed between the burner venturi top and the top surface of the outer box. be able to. Therefore, when the packaged product is dropped on the top surface, the spacer portion acts as a shock absorbing portion to absorb the impact on the burner venturi when the top surface is dropped, and can receive the load applied to the burner venturi.

It is desirable that the burner holding member is formed of a cylinder of a resin molded product.
In this case, when the top surface of the packaged product is dropped, the impact absorbing portion of the burner holding member is elastically deformed or damaged to absorb the impact received by the burner venturi when the top surface is dropped, and the load applied to the burner venturi can be reliably received. Further, since it is a resin molded product, the dimensions of each part of the burner holding member can be accurately and easily manufactured as designed by injection molding or the like. Further, if the burner holding member is formed of corrugated cardboard, styrofoam, etc., it may rub against the burner venturi top due to vibrations such as transportation to generate powder, and this powder may stay in the burner venturi and cause a problem in burner combustibility. However, by forming the burner holding member with a resin molded product, the above-mentioned problems do not occur. Moreover, since it is a resin molded product, it does not scratch the burner venturi due to vibration during transportation or the like.

The shock absorbing portion may be formed of a tubular body provided with a slit.
In this case, even if it is difficult to apply a large impact force because the burner venturi is relatively lightweight, the shock absorbing part is easily elastically deformed or damaged when the top surface of the packaged product is dropped, and the impact when the top surface is dropped is received by the burner venturi. Can absorb the load and reliably receive the load applied to the burner venturi.

The shock absorbing portion may be formed of a tubular body provided with ribs extending in the length direction.
In this case, the ribs increase the strength of the shock absorbing portion. Therefore, if the burner venturi is relatively heavy and a large impact force is likely to be applied, the impact absorbing part is elastically deformed without being easily destroyed when the top surface of the packaged product is dropped, and the impact received by the burner venturi when the top surface is dropped is applied. It absorbs and can reliably receive the load applied to the burner venturi.

The shock absorbing portion may be formed of a tubular body having a thinner wall thickness toward the tip end, which is a contact portion with the top surface portion of the outer box.
In this case, when the top surface of the packaged product is dropped, the impact absorbing portion is easily elastically deformed or damaged from the portion near the tip away from the burner venturi, so that it is possible to prevent a large impact from being applied to the burner venturi when the top surface is dropped. Therefore, it is possible to surely prevent the burner mounting plate or the stove body from being deformed by suppressing the large inertial movement of the burner venturi.

As described above, according to the burner holding member according to the present invention, even if the packaged product is dropped on the top surface, it is possible to prevent the burner mounting plate for fixing the burner venturi or the stove body from being deformed, and the burner venturi can be used. It is held in a predetermined set position on the stove body without being displaced. Therefore, the correlation with the accessory parts of the gas burner does not deviate, and the functions of the gas burner and its surrounding parts do not become abnormal. Therefore, the reliability of the packaging of the gas stove is improved.

Hereinafter, embodiments of the present invention will be described.
When packing the gas stove, the gas stove is housed in a corrugated cardboard box which becomes a rectangular outer box 2 in a state of being disassembled for each main part. For example, as shown in FIG. 1, the gas stove is disassembled into a stove body 3, a top plate 41, a burner ring upper 42, a burner ring lower 43, a burner body 52, a burner head 53, a trivet 44, an operation knob 45, and the like. .. The burner venturi 5 and the gas valve 46 are mounted and fixed to the burner mounting plate 31 mounted in the case 30 on the stove body 3.

In the packing structure of the gas stove shown in FIG. 1, the stove body 3 housed in the outer box 2 has a pair of lower cushions 62 arranged on the short side of the bottom of the stove body 3 and an upper part of the stove body 3. It is held in a state of being protected from an external impact by a pair of upper cushions 61 arranged on the longitudinal side. A spacer 63 is interposed between the pair of lower cushions 62. At the bottom of the outer box 2, a trivet storage cushion 64 on which the trivet 44 is arranged, a fixed pad 65 for holding the burner body 52 and the burner head 53 are arranged. A top plate 41 is held on the upper part of the pair of upper cushions 61, and a top pad 66 is arranged on the upper surface of the top plate 41. The top pad 66 houses the burner ring upper 42, the burner ring lower 43, the operation knob 45, the battery 47, and the like. Then, the lid piece 21 (top surface portion of the outer box) of the outer box 2 is closed so as to press the top surface pad 66 and the upper cushion 61 from above.

By the way, the gas burner in the gas stove has a burner venturi 5, a burner body 52, and a burner head 53 as main configurations. The burner venturi 5 is fixed with screws or the like so as to maintain a position correlation with the burner mounting plate 31 mounted in the stove body 3. The burner venturi 5 is a portion of the gas burner that serves as a mixing pipe for mixing the fuel gas and the primary air, and is formed of a substantially L-shaped pipe body. The burner venturi top 51 forming the upper end portion on the outlet side of the burner venturi 5 is formed in a double cylindrical shape inside and outside, and the burner venturi top 51 forms a disc-shaped burner body 52 and a flame port. A disk-shaped burner head 53 is attached. In the packed state, as described above, the burner body 52 and the burner head 53 are removed from the burner venturi 5. In the present embodiment, the burner venturi 5 is made of cast metal and is heavier than the processed product of the stainless steel pipe. In the present invention, the burner venturi 5 is not limited to the cast product, but may be a processed product of a stainless steel pipe. The burner mounting plate 31 for fixing the burner venturi 5 and the case 30 of the stove body 3 for mounting the burner mounting plate 31 are formed of a metal plate such as a stainless steel plate.

In the packed state, the burner venturi 5 is fixed to the burner mounting plate 31 of the stove body 3, and a space is opened above the burner venturi 5 between the burner venturi 5 and the lid piece 21 of the outer box 2. .. Therefore, when the outer box 2 containing the stove body 3 is dropped from the top surface side, the burner venturi 5 moves by inertia due to the impact when the top surface is dropped, and the burner mounting plate 31 or the burner mounting plate 31 is mounted. There is a risk of deforming the case 30 of the stove body 3.

Therefore, in the present embodiment, in the packing structure of the gas stove, as shown in FIGS. 2 and 3, a burner holding member 1 is arranged with respect to the burner venturi 5 of the stove main body 3, and the burner holding member 1 is covered from above. I try to hold it with one piece 21. That is, the burner holding member 1 absorbs the impact when the packaged product, which is the outer box 2 containing the stove body 3, is dropped on the top surface, and suppresses the burner venturi 5 of the stove body 3 from moving due to inertia. Used to do.

The burner holding member 1 is formed of a resin molded product made of a circular tubular body 10, and is formed so as to project from the outer peripheral surface of the tubular body 10 with reference to FIG. 4, and is formed so as to project from the outer peripheral surface of the tubular body 10. The support portion 12 formed by the flange portion 11 abutting against the flange portion 11 and the lower tubular body 10 portion of the flange portion 11 and inserted and arranged in the burner venture top 51, and the upper tubular body 10 portion of the flange portion 11 It has a spacer portion 13 which is formed and is supported on the burner venture top 51 and is arranged so as to be in contact with the inner surface of the lid piece 21 of the outer box 2 which is the top surface portion of the outer box.

The rectangular outer box 2 is formed of a piece of corrugated cardboard. The top surface of the outer box 2 is composed of a lid piece 21. The lid piece 21 has four pieces, two cover pieces 21a and 21b on the short side and two lid pieces 21c and 21d on the long side, and when each cover piece 21 is closed, the short side side. The portions of the lid pieces 21a and 21b on the long side overlap with the lid pieces 21c and 21d on the long side and are doubled, but the lid pieces on the long side are between the two lid pieces 21a and 21b on the short side. Only 21c and 21d are arranged to form a single layer. In the present embodiment, due to the arrangement configuration of the gas burner of the gas stove, the burner holding member 1 is arranged at a position where the tip (the tip of the spacer portion 13) abuts only on the long side lid pieces 21c and 21d. Depending on the model of the gas stove, the holding member 1 is arranged at a position where the short side lid pieces 21a and 21b and the long side side lid pieces 21c and 21d overlap and abut on the double portion. May be good.

In the burner holding member 1, the support portion 12 is formed in a cylindrical shape having an outer diameter that substantially contacts the inner surface of the outer cylinder portion of the burner venturi top 51, and is arranged in the burner venturi top 51. The support portion 12 can stably support the burner holding member 1 on the burner venturi top 51. Therefore, the burner holding member 1 does not rattle, shift or come off, or damage the burner venturi 5 due to vibration during transportation of the packaged product. The flange portion 11 is formed in an annular shape having an outer diameter covering the upper end of the outer cylinder portion of the burner venturi top 51 and is locked to the upper end of the burner venturi top 51. The flange portion 11 determines the mounting position of the burner holding member 1 with respect to the burner venturi top 51 and the height position of the spacer portion 13. The spacer portion 13 is formed in a cylindrical shape having a length extending from the burner venturi top 51 to the inner surface of the lid piece 21 of the outer box 2 in the packed state of the stove body 3, and is arranged on the burner venturi top 51. The spacer portion 13 is arranged at a predetermined height position on the burner venturi top 51 by determining the position by the flange portion 11, and is interposed between the burner venturi top 51 and the lid piece 21 so as to be stretched. The spacer portion 13 is a shock absorbing portion that absorbs the impact when the top surface of the packaged product, which is the outer box 2 containing the stove body 3, is dropped from the top surface side.

According to the above configuration, when the packaged product is dropped on the top surface, the spacer portion 13 serving as the shock absorbing portion absorbs the impact received by the burner venturi 5 when the top surface is dropped and receives the load applied to the burner venturi 5. Therefore, it is possible to prevent a situation in which the burner venturi 5 moves by inertia and the burner mounting plate 31 for fixing the burner venturi 5 or the case 30 of the stove body 3 for fixing the burner mounting plate 31 is deformed.

Since the burner holding member 1 is formed of a tubular body 10 of a resin molded product, the spacer portion 13 of the burner holding member 1 is elastically deformed or damaged when the top surface of the packaged product is dropped, and the burner venturi 5 receives the top surface drop. The impact of time can be absorbed, and the load applied to the burner venturi 5 is reliably received. Further, since it is a resin molded product, the dimensions of each part of the burner holding member 1 can be accurately and easily manufactured as designed by injection molding or the like. Further, when the burner holding member 1 is formed of corrugated cardboard, foamed styrol, or the like, it rubs against the burner venturi top 51 due to vibrations such as transportation to produce corrugated cardboard or foamed styrol powder, and this powder stays in the burner venturi 5 and burns the burner. Although there is a possibility of causing a problem in the property, the above-mentioned problem does not occur by forming the burner holding member 1 with a resin molded product. Further, since it is a resin molded product, the burner venturi 5 is not scratched by vibration during transportation or the like. As the resin forming the burner holding member 1, it is preferable to use ABS from the viewpoint of moldability and cost, but the resin is not limited to ABS, and various resin materials such as PP and PC can be used.

The spacer portion 13 is formed with four ribs 14 (projections protruding from the outer peripheral surface of the tubular body 10) extending in the length direction at equal intervals in the circumferential direction. The rib 14 increases the strength of the spacer portion 13. Therefore, when the burner venturi 5 is formed from a casting and is relatively heavy and therefore a large impact force is likely to be applied, the spacer portion 13 is elastically deformed without being easily broken when the top surface of the packaged product is dropped, and the burner venturi 5 is formed. It is possible to absorb the impact when the top surface is dropped and reliably receive the load applied to the burner venturi 5. In particular, the rib 14 is formed so as to extend in the axial direction of the spacer portion 13 from the flange portion 11 which is the base end portion of the spacer portion 13. As a result, the strength of the base end portion of the spacer portion 13 is strengthened, so that when the spacer portion 13 receives an impact when the top surface of the packaged product is dropped, the base end portion of the spacer portion 13 bends into the burner venturi 5. It is possible to prevent a situation in which such a load cannot be substantially received. The rib 14 is not limited to the above configuration, and the length, number, position, etc. of the rib 14 can be appropriately formed according to the model of the gas stove, the configuration, size, weight, etc. of the burner venturi 5. Alternatively, the rib 14 may not be provided.

The wall thickness of the spacer portion 13 is formed thinner toward the tip of the outer box 2 which is the contact portion with the lid piece 21 (see FIG. 3). As a result, the spacer portion 13 is stronger in the base end side portion than in the tip end side portion in terms of strength. Therefore, when the top surface of the packaged product is dropped, the spacer portion 13 is liable to be elastically deformed or damaged from the portion of the spacer portion 13 near the tip away from the burner venturi 5, so that it is difficult for the burner venturi 5 to be subjected to a large impact when the top surface is dropped. .. Further, the spacer portion 13 can be satisfactorily absorbed by the impact when the top surface of the packaged product is dropped without the spacer portion 13 being bent in the center at the base end side. Therefore, when the top surface of the packaged product is dropped, the large inertial movement of the burner venturi 5 is suppressed, and the burner mounting plate 31 or the case 30 of the stove body 3 can be reliably prevented from being deformed. The wall thickness of the spacer portion 13 is not limited to the above configuration, and may be formed to be a uniform thickness along the axial direction, and the wall thickness itself is also used in the gas stove model and the burner venturi 5. The thickness can be adjusted appropriately according to the configuration, size, weight, and the like.

From the above, according to the burner holding member 1 according to the present embodiment, even if the packed product is dropped from the top surface, it is possible to prevent the burner mounting plate 31 for fixing the burner venturi 5 or the case 30 of the stove body 3 from being deformed. The burner venturi 5 is held at a predetermined set position on the stove body 3 without being displaced. Therefore, the correlation with the accessory parts of the gas burner does not deviate, and the functions of the gas burner and its surrounding parts do not become abnormal. Therefore, the reliability of the packaging of the gas stove can be further improved.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the claims and the equivalent range.
For example, as shown in FIG. 5, the spacer portion 13 may be formed with a slit 15 penetrating the wall surface. In this case, even if the burner venturi 5 is relatively lightweight and it is difficult to apply a large impact force, the spacer portion 13 is easily elastically deformed or damaged when the top surface of the packaged product falls, and the burner venturi 5 receives the top surface drop. The impact of the burner venturi 5 can be absorbed and the load applied to the burner venturi 5 can be reliably received. The slits 15 shown in FIG. 5 are formed in an elongated hole shape extending in the axial direction of the spacer portion 13, and four slits 15 are formed at equal intervals in the circumferential direction of the spacer portion 13, and the entire spacer portion 13 is formed when the top surface of the packaged product is dropped. It is easy to be elastically deformed, but not limited to this, the shape, position, number, etc. of the slit 15 should be appropriately formed according to the model of the gas stove, the configuration, size, weight, etc. of the burner venturi 5. Can be done.

Further, in the above embodiment, the gas stove of the packaged object is an example of a single gas stove provided with one gas burner, but it can be applied to a gas stove provided with two or more gas burners, and a gas stove provided with a plurality of gas burners can be applied. In this case, it is preferable to arrange the burner holding member 1 on all of the burner venturis 5 of each gas burner. However, in the case of a gas stove equipped with a plurality of gas burners, due to the arrangement of each gas burner, the configuration, size, weight, etc. of each burner venturi 5, all the burner venturis 5 are inertial due to the impact when the top surface of the packaged product is dropped. The burner holding member 1 may be arranged with respect to a part of the burner venturis 5 among the plurality of burner venturis 5 so as to prevent the movement.
