Description

  The present invention relates to improvement of a barbecue stove used in the outdoors and the like.

  In recent years, outdoor activities have become active in Japan, and family members and friends are increasingly using a barbecue stove at campsites.

  Along with such a change in the way of spending leisure time, barbecue stoves are becoming increasingly popular in Japan.

  By the way, in recent years, various products have begun to be produced in China and other countries where labor costs are low, and the wave of lower product prices has come to the fore, and this barbecue stove is no exception.

  For this reason, manufacturers are looking for a structure that can be provided at a lower price.

  Furthermore, on the other hand, the quality of the product is strictly questioned from the viewpoint of consumer protection. If there is a problem with the quality of the stove due to discoloration or the like, it is often the case that a complaint is sent to the dealer.

  Therefore, in order to prevent discoloration due to heat of the outer plate, the barbecue stove has a double wall structure consisting of an inner plate and an outer plate, and charcoal is burned in a space surrounded by the inner plate, There has been proposed a barbecue stove configured such that burning charcoal does not come into direct contact (Patent Document 1).

Japanese Utility Model Laid-Open No. 5-69501.

  However, in the case of the barbecue stove configured as described above, since the burning charcoal directly hits the inner plate, the rigidity is lowered by thermal creep, and the inner plate is thermally deformed. For this reason, it is necessary to use a thick board for the inner board. In such a case, a large-scale tool or manufacturing machine must be used, and the number of processing steps increases. As a result, it becomes expensive in price, and under the current trend of lowering prices, the sales competitiveness is lowered. Furthermore, such a barbecue stove is heavy and difficult to handle.

  The present invention has been made in view of such a situation. The outer plate is not discolored by heat as much as possible, is light in weight, and the inner plate is heated even when a thin plate is used. The object is to provide a barbecue stove that is difficult to deform.

  A barbecue stove according to the present invention is a barbecue stove having a box-shaped main body portion that is formed by an outer plate having four side surfaces and a bottom surface and is opened upward, and an inner plate disposed therein. The plate is formed into a groove-like shape widened upward as viewed from one side surface, and a space is formed between the inner plate and from the bottom portion and both sides thereof upward. A wire mesh member formed in a mesh shape with a linear member is disposed on the raised side surface portion, and the upper end portion of the inner plate is relatively locked to the upper end portion of the wire mesh member. To do.

  According to the barbecue stove according to the present invention configured as described above, the burning charcoal or the like is held in contact with the wire mesh member and is in direct contact with the inner plate arranged with the space therebetween. do not do. Therefore, the inner plate can be prevented from being deformed by heat as much as possible. For this reason, the inner plate is made as thin as possible, specifically, the inner plate of the conventional barbecue stove is 0.6 mm to 0.00 mm. What used a steel plate of about 8 mm can use a steel plate having a thickness of 0.3 mm or less. Therefore, processing becomes easy, it can be manufactured at low cost, and in terms of performance, the outer plate is not discolored by heat and can be reduced in weight. Moreover, since the wire mesh member is constituted by a solid metal linear member and the wire mesh member and the inner plate are engaged at the upper end portion, the inner plate and the metal plate Combined with the net-like member, rigidity can be increased and thermal deformation caused by the burning charcoal can be reduced as much as possible. Furthermore, the inner plate can effectively reflect the radiant heat upward, so that it is possible to heat-treat the food placed above the wire mesh member with a small amount of charcoal, and as a stove a high thermal efficiency. Obtainable.

  In the barbecue stove, in order to form a space between the inner plate and the wire mesh member, a protrusion is formed on one member or both members of the inner plate and the wire mesh member toward the other party. When configured, it can be realized at low cost without increasing the number of parts.

In the barbecue stove, the inner plate is not disposed on at least one of the four side surfaces, and a vent is formed on a side surface of the outer plate on which the inner plate is not disposed. When the inner plate is made of a plated steel plate or a stainless steel plate, fresh air is supplied to the inside from the vent, so that combustion continues smoothly and the inner plate efficiently reflects heat upward. In addition, since the outer plate portion is always in contact with the low-temperature air flowing in from the vent, heat in the combustion space is transmitted to the side surface and the bottom surface of the outer plate portion. It is difficult to discolor due to heat.
In such a configuration, when the inner plate is not disposed on both side surfaces of the four side surfaces, and the vent is formed on the side surface of the outer plate on which the inner plate is not disposed, fresh air is generated. Passing through the combustion space from right to left or vice versa, or fresh air is supplied from the vents on both sides, the combustion gas burns in the combustion space and the combustion gas rises upward. Extremely efficient combustion is performed.

In the barbecue stove, a portion of the upper end portion of the inner plate that interferes with the linear member that is provided laterally of the wire mesh member is cut out, and the upper end portion of the inner plate has an inverted U shape. Bent,
The inverted U-shaped part is locked to the linear member at the upper end on both sides of the wire mesh member,
The locking is inserted from the outside between the linear member at the upper end and the linear member immediately below the inside, into the inverted U-shaped portion of the inner plate, If the inserted U-shaped part is covered with the linear member from above, the temperature of the inner plate and the wire mesh member will rise, causing some deformation and distortion. As a result, both are more reliably locked.

  According to the barbecue stove according to the present invention configured as described above, the outer plate is not discolored by heat as much as possible, is light in weight, and the inner plate is thermally deformed even if a thin plate is used. It is possible to provide a difficult barbecue stove.

It is a disassembled perspective view which shows each structure of the wire-mesh-like member, inner plate, and outer plate which comprise the barbecue stove shown in FIG. It is a side view which shows the structure of the barbecue stove shown in FIG.

  Hereinafter, the barbecue stove concerning the Example of this invention is demonstrated concretely, referring drawings.

Example 1
Embodiments of the present invention will be described below with reference to the drawings.

  In FIG. 1 (a), A is a barbecue stove, and this barbecue stove A is an outer plate having four side surfaces S1, S2, S3, S4 and a bottom surface 1B as shown in FIG. 1 (a) or FIG. 1 and a main body portion A1 configured in a box-like shape opened upward, and disposed on the inner side of the main body portion A1 and on the side of the side surface S2 (in the direction of arrow Y1 in FIG. 3) and an inner plate 2 composed of a plate-like member that is gradually widened upward, and a bottom portion so that a space 4 is formed inward of the inner plate 2. A wire mesh member 3 formed by welding a solid linear member into a mesh shape in a groove-like form in which a side portion raised upward from both sides is gradually widened upward in a side view; Have Further, in this embodiment, both end portions (both upper end portions) of the wire net-like member 3 in the groove shape are for increasing rigidity against thermal creep as shown in FIG. 1 (a) or FIG. Further, they are connected to each other by a cross member 3c made of a linear member.

  As shown in FIG. 1 (a) or FIG. 2, on the inner wall side of the side surfaces S2, S4 of the main body portion A1, the inner plate 2 and the wire mesh member 3 are spaced from the bottom surface 1B. The flange member 12 is provided with a locking groove 12a that holds the linear member 3s on the bottom surface of the wire net-like member 3 from below and is substantially U-shaped in plan view. Has been. However, the configuration in which the inner plate 2 and the wire mesh member 3 are held or placed on the main body portion A1 is not limited to the implementation cooling, and can be realized in other forms.

As shown in FIG. 2 or FIG. 1 (b), the inner plate 2 has an inverted U shape or an inverted V shape at both upper ends thereof which are in the groove shape (this specification and claims). The portion 2a having the inverted U shape is latched by the linear member 3u at the upper end on both sides of the wire mesh member 3. Yes. Such locking is performed by inserting the inverted U-shaped portion 2a of the inner plate 2 from the outside between the linear member 3u at the upper end and the linear member 3d immediately below the linear member 3u. Then, as shown in FIG. 1 (b), the reverse U-shaped portion 2a covers the linear member 3u from above.
For this reason, except for both end portions of the upper end portion of the inner plate 2, a portion that interferes with the linear member 3k that is laterally provided (provided in a direction orthogonal to the longitudinal direction) of the wire mesh member 3. 2e is cut out in a rectangular shape as shown in FIGS. 1 (a), 1 (b), and 2. FIG. In this embodiment, since both ends of the wire mesh member 3 protrude from both ends of the inner plate 2 at the both end portions, it is not necessary to form the notches.

Such a locking structure is preferable in the following points. That is, when the temperature of the inner plate 2 and the wire mesh member 3 rises due to combustion, the temperature rise of the wire mesh member 3 and the inner plate 2 is different depending on whether or not they are in direct contact with charcoal. In addition, the wire mesh member 3 has a so-called “heat dripping” peculiar to the linear member, while the inner plate 2 has a surface distortion, and the thermal expansion amount in the width direction X of the wire mesh member 3. Although the thermal expansion amount in the width direction X of the inner plate is different from that of the inner plate, the thermal deformation or the like is configured to change (thermal deformation) to the side where the engagement between the two becomes stronger. However, it goes without saying that, in addition to this embodiment, the upper end portion of the inner plate 2 can be relatively locked to the upper end portion of the wire mesh member 3 by other forms.

  In this embodiment, the bottom surface of the inner plate 2 includes a plurality of rectangular protrusions 2B as viewed from the side S2 so as to extend along the groove longitudinal direction Y (see FIG. 2) (this embodiment). In the example, it is formed 2) apart from each other. Of course, instead of this configuration, a protrusion protruding downward may be formed on the bottom surface portion of the wire mesh member 3, or a protrusion protruding toward the other party may be formed on both the inner plate 2 and the wire mesh member 3. May be.

  By providing the flange member 12 and the projection 2B, a space 8 is formed between the bottom surface 1B of the main body portion A1 and the inner plate 2 inside the main body portion A1, as shown in FIGS. At the same time, the space 4 (see FIG. 1) is also formed between the inner plate 2 and the wire mesh member 3.

  The inner plate 2 does not exist inside the both side surfaces S2 and S4 of the outer plate 1, and a vent hole 5 is formed on both side surfaces S2 and S4. Air is configured to be sent to a combustion space inside the wire mesh member 3. By the vent hole 5, fresh air is supplied on the wire mesh member 3, that is, to the charcoal burned in the combustion space, and the combustion is performed smoothly and efficiently. The flange member 12 attached to the inner surfaces of the side surfaces S2 and S4 is also formed with a vent so as to overlap the vent 5 so as not to block the vent 5.

  Also, a plurality of openings 6 are formed in the side surfaces S1 and S3 of the outer plate 1 so as to be trapped in the space 8 (see FIG. 1) between the inner plate 2 and the outer plate 1. Heat is released to the outside air, and outside air having a low temperature is introduced so that the inner plate 2 and the outer plate 3 do not reach a predetermined temperature or higher. That is, the inner plate 2 heated by the charcoal that burns on the wire mesh member 3 and the outer plate 3 outside thereof are appropriately cooled to prevent thermal deformation as much as possible.

  Further, in the case of this barbecue stove A, as shown by two-dot chain lines in FIGS. 1 (a) and 3, stove legs 9 are arranged at the four corners of the main body portion A1.

  By the way, in the case of the barbecue stove A according to the present embodiment, the outer plate 1 has a thickness of about 0.3 to 0.5 mm, and the inner plate 2 has a thickness of about 0.15. The wire diameter of the wire member of the wire mesh member 3 is approximately 1.5 mm. For this reason, in the case of the present barbecue stove A, it becomes possible to achieve a significant weight reduction as compared to the conventional one. Of course, the said plate | board thickness and wire diameter are only illustrations, and are not limited to the thing of this specific numerical value. In the case of this embodiment, a plated steel plate or a stainless steel plate is used for the inner plate 2 so that radiant heat can be used more effectively. Further, a steel plate is used for the outer plate 1 and its surface is painted. Further, the wire mesh member is made of steel and is formed into a wire mesh shape, which is then plated. However, these are merely examples, and the present invention is not limited to these.

And the barbecue stove A concerning this invention comprised as mentioned above acts as follows. That means
When performing a barbecue, the charcoal is placed on the wire mesh member 3 and ignited by an ignition device or the like, and the charcoal burns on the wire mesh member 3. Then, outside the wire mesh member 3, the inner plate 2 is disposed so as to surround the wire mesh member 3 from the outside except for the upper end portion, and heat such as charcoal is generated by the inner plate 2. Reflected and emitted above the barbecue stove A.
For this reason, the combustion heat, radiant heat, and radiant heat of charcoal are effectively applied to the food (not shown) placed on the barbecue stove A. As a result, the foodstuff arrange | positioned above this barbecue stove A will be efficiently baked by a far-infrared ray etc.

On the other hand, the inner plate 2 is provided with a space 4 between the inner mesh member 3 and the inner plate 2 so that the inner plate 2 does not almost directly hit the hot coal that burns. Even if the plate 2 is formed of a thin plate, it is not greatly deformed by heat.
And since the heat of charcoal is reflected by the inner plate 2 and does not directly act on the outer plate 1 except for the side plates S2 and S4, the bottom surface 1B of the outer plate 1 and the inner plate 2 Since the space 8 is formed between them, the paint on the outer plate 1 is not discolored by heat. Moreover, although the heat of charcoal directly hits the side plates S2 and S4, the vent 5 is formed in such a portion, and it is in a cooled state by flowing low temperature outside air. There will be no discoloration due to heat.

  And in the case of the barbecue stove A concerning a present Example, since a thin material can be used for the inner board 2 as mentioned above, weight reduction can be achieved significantly compared with the conventional one. Further, it can be manufactured at low cost. In addition, although the wire mesh member 3 uses the solid wire, since it is mesh shape, it is restrained lightweight in weight.

  Further, since the wire mesh member 3 has a groove-like shape widened at the upper end in a side view, the amount of charcoal used can be greatly reduced.

  It goes without saying that the present invention is not limited to the above-described embodiments, and can be implemented in various forms within the scope based on the technical idea of the present invention.

  The barbecue stove according to the present invention can be used as an outdoor stove.
