In the conventional stove, when the ash is cleaned after using the stove, it is necessary to turn over the main body 2 or the frame body 8 to drop the ash, which is troublesome.
In addition, the thermal power may vary depending on the type of solid fuel, and there are cases where it is desired to adjust the amount of air supplied to the solid fuel.
The present invention aims to solve such problems.

The stove for a barbecue includes a main body having an open top surface and a bottom plate on which solid fuel is placed, and a hole through which air can pass through the bottom plate, and below the bottom plate so as to be spaced apart from the bottom plate. And an ash receiving member that is detachably attached to the main body via a handle.
Further, at least two receiving pieces are provided in the height direction on one of the side surfaces of the handle or the main body, and an abutting piece that is detachably fitted to the receiving piece is provided on the other side. The ash receiving member is at least between the first height position separated from the bottom plate of the main body and the second height position lower than the first height position by fitting the contact piece and the receiving piece. , Selectively attached to the body.

1. A hole is formed in the bottom plate of the main body, and the bottom plate and the ash receiving member are provided with a space therebetween, so that air is supplied to the fixed fuel through the space and the hole. The ash after combustion of the fixed fuel falls onto the ash receiving member through the hole. Since the ash receiving member is detachably attached to the main body, the ash receiving member may be removed from the main body when cleaning the ash. Therefore, the workability when cleaning the ash becomes easier.
2. Since at least two receiving pieces are provided in the height direction, the ash receiving member is attached to at least the first height position and the first height by attaching the contact pieces to receiving pieces having different heights. It can be selectively attached to the main body between a second height position lower than the position. That is, the distance between the ash receiving member and the bottom plate of the main body can be changed. As a result, the amount of air supplied to the solid fuel on the bottom plate through the gap and the hole changes, so that it is possible to cope with a case where the amount of air supplied to the solid fuel is desired to be adjusted.

It is a disassembled perspective view of the stove for barbecue. (a), (b) is a front view which shows the state which attached the ash receiving member to the single row. It is an enlarged view of a receiving piece. It is a front view of the stove manufactured for Experiment 1. It is a top view of the stove of FIG. It is a perspective view of a firebox. It is a front view of the conventional stove for barbecue. It is a perspective view of another stove for barbecue.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an exploded perspective view of a barbecue stove 1 according to the present invention. The stove for barbecue 1 has a main body 2 having an upper surface opened and configured by a first bottom plate 20 and four first side plates 21, and a plurality of bar-like leg pieces 3 projecting downward from the first side plate 21. The ash receiving member 4 which is a box having an upper surface opened is provided. The first bottom plate 20 is provided with a rooster 23 provided with a large number of holes 22 through which air can pass, and solid fuel (not shown) such as charcoal is arranged on the rooster 23. The main body 2 and the ash receiving member 4 are usually formed from a metal plate in view of flame retardancy.

The ash receiving member 4 is formed in a rectangular parallelepiped shape with four second side plates 41 erected on the second bottom plate 40, and a pair of second side plates 41 facing each other is connected to the corresponding first side plate 21. Two handles 5 to be attached are provided.
When the main body 2 is used, the solid fuel on the rooster 23 is ignited in a state where a net (not shown) is placed on the opening of the main body 2 and food is placed on the net. The ash that is the burning husk of the solid fuel falls through the hole 22 of the rooster 23 to the second bottom plate 40 of the ash receiving member 4.

  Each handle 5 is formed integrally from a metal bar, and a pair of vertical pieces 51 spaced along the upper side of the second side plate 41 and a contact piece extending horizontally so as to connect the upper ends of both vertical pieces 51. 50, a gripping piece 52 that extends obliquely outward from the contact piece 50 and grips by the user, and is provided horizontally outward from the lower end of the vertical piece 51 and is rotatably fitted to the second side plate 41. The shaft piece 53 is provided. When the user carries the ash receiving member 4, the grip piece 52 of the both handles 5 is gripped.

  On the first side plate 21 corresponding to the handle 5, a receiving piece 6 that receives and supports the contact piece 50 is provided. As shown in an enlarged view in FIG. 3, the receiving piece 6 is formed from a receiving plate 61 that extends obliquely upward from the first side plate 21, and receives the contact piece 50 at the lower end portion of the upper surface of the receiving plate 61. However, the receiving piece 6 is not limited to this shape as long as it can support the contact piece 50. The two receiving pieces 6 are arranged in the horizontal direction so as to receive the contact piece 50 to form one receiving piece row 60, and two receiving piece rows 60 are provided along the height direction. In FIG. 1, two receiving piece rows 60 are provided along the height direction, but the number is not limited to two, and may be three or more. Moreover, although all the receiving pieces 6 are described in FIG. 1 as being formed by processing one metal plate, each receiving piece 6 may be formed separately.

In order to attach the ash receiving member 4 to the main body 2, the handle 5 is rotated around the shaft piece 53, and the contact piece 50 is hooked on one of the receiving piece rows 60. The height position of the ash receiving member 4 can be changed by selectively hooking and fitting the contact piece 50 to one of the receiving piece rows 60.
In order to transport the stove 1 for barbecue, the handle 5 is lifted. At this time, the abutting piece 50 is detached from the receiving piece row 60, but the upper end of the second side plate 41 of the ash receiving member 4 comes into contact with the first bottom plate 20 of the main body 2. To be transported.

  2A and 2B are front views showing a state where the ash receiving member 4 is attached to the single row 60. FIG. The state in which the ash receiving member 4 is attached to the higher receiving piece row 60 is shown in FIG. 2 (a), and the state in which the ash receiving member 4 is attached to the lower receiving piece row 60 is shown in FIG. 2 (b). Show. As described above, since the grip piece 52 extends upward and outward from the contact piece 50, the tip of the grip piece 52 faces outward from the main body 2 when the ash receiving member 4 is attached to the main body 2. is seperated. Thereby, even if the main body 2 is heated, the gripping piece 52 is not immediately heated.

  The height position of the ash receiving member 4 in FIG. 2 (a) is defined as a first height position, and the height position of the ash receiving member 4 in FIG. 2 (b) is defined as a second height position. Since the second height position is lower than the first height position and the distance between the second side plate 41 of the ash receiving member 4 and the first bottom plate 20 of the main body 2 is wide, the solid fuel passes through the holes 22. There is a lot of air hitting. That is, solid fuel is easy to burn. The applicant sets the distance between the second side plate 41 of the ash receiving member 4 at the first height position and the first bottom plate 20 of the main body 2 to several mm, and the second side plate of the ash receiving member 4 at the second height position. Although the distance between 41 and the first bottom plate 20 of the main body 2 is assumed to be 2-3 cm, it is not limited to this distance.

(Effect of the embodiment)
1. When using the stove 1 for barbecue, air is supplied to the fixed fuel through the space between the main body 2 and the ash receiving member 4 and the hole 22 of the main body 2. The ash after combustion of the fixed fuel falls onto the ash receiving member 4 through the hole 22. Since the ash receiving member 4 is detachably attached to the main body 2, the ash receiving member 4 may be removed from the main body 2 when cleaning the ash. Therefore, the workability when cleaning the ash becomes easier.
2. Since at least two receiving pieces 6 are provided in the height direction, the distance between the ash receiving member 4 and the bottom surface of the main body 2 can be changed by attaching the contact pieces 50 to the receiving pieces 6 having different heights. I can do it. Thereby, since the amount of air supplied to the solid fuel through the interval changes, it is possible to cope with the case where it is desired to adjust the amount of air supplied to the solid fuel.

(Experimental result)
The applicant has conducted the following Experiment 1 and Experiment 2 in order to improve the combustibility of the conventional barbecue stove 1, and has come up with the barbecue stove 1 according to the present invention.
Experiment 1
First, the hole 22 is removed from the main body 2 of the conventional barbecue stove 1 shown in FIG. 7, and a rooster is provided on the bottom surface of the main body 2 instead, and the ash receiving member 4 is suspended from the main body 2 as shown in FIG. A stove 1 was prototyped. The bottom surface of the main body 2 and the ash receiving member 4 are considerably spaced from each other. That is, the amount of air flowing into the main body 2 from the rooster 23 is considerably larger than that of the conventional product.

As shown in the plan view of FIG. 5, five fire-inducing devices 9 are arranged at the center of the bottom surface of the main body 2 and four at the corners to ignite the charcoal 10 as a fixed fuel. Here, as shown in FIG. 6, the fire igniter 9 is provided with a perforated plate 92 in a cylindrical body 90 having a hole 91 through which air passes at the lower end, and ignites the lower side of the perforated plate 92. The agent 93 is arranged. The charcoal 10 can be easily ignited by inserting the charcoal 10 above the perforated plate 92 and igniting the igniting agent 93. An amount of charcoal 10 in the same amount as that in the fire-fired device 9 was placed in the main body 2 so as to cover the fire-fired device 9. Similarly, a fire-fired device 9 was also arranged in the conventional barbecue stove 1 shown in FIG. 7 to ignite the charcoal 10, and the combustion time, temperature on the rooster 23, and cooking time were measured. The results are shown in Table 1.

  From this result, it was found that the stove 1 in FIG. 4 is ignited earlier, but the combustion time is shorter, the fire rises from the charcoal 10, and it is dangerous for cooking the food. This is considered to be because the inflow of air into the first bottom plate 20 of the main body 2 is too good. Therefore, from this result of Experiment 1, the applicant has conceived of adjusting the amount of air flowing into the main body 2.

Experiment 2
Next, the applicant made a prototype of the stove 1 shown in FIG. 1, adjusted the height of the ash receiving member 4 as shown in FIGS. 2 (a) and 2 (b), and confirmed the combustibility. 2A, the distance between the second side plate 41 of the ash receiving member 4 and the first bottom plate 20 of the main body 2 is several millimeters. In FIG. The distance between the second side plate 41 of the member 4 and the first bottom plate 20 of the main body 2 is 2-3 cm. Further, the applicant modified the stove 1 shown in FIG. 8 so that the height of the ash receiving member 4 can be adjusted. The arrangement position of the pyrotechnic device 9 and the amount of charcoal 10 used are the same as in Experiment 1.

  First, the height of the ash receiving member 4 is set to the second height position, and charcoal is ignited. The time required for the charcoal to ignite and the flame to rise was about 35 minutes for the stove 1 shown in FIG. 2 (b) and about 30 minutes for the stove 1 modified from the stove 1 shown in FIG.

After the flame went up, the ash receiving member 4 was set at the first height position to reduce the amount of air flowing into the first bottom plate 20. About 10 minutes after setting to the first height position, both the stove 1 settled down and became ready for cooking. Therefore, it was confirmed that adjusting the height of the ash receiving member 4 is effective in stabilizing the flame. It seems that setting the ash receiving member 4 to the first height position so as to reduce the amount of air flowing into the first bottom plate 20 before the flame starts to rise can start cooking the food early. .
Similarly, the applicant has confirmed that the stove 1 manufactured in an overseas factory has an effect of stabilizing the flame by adjusting the height of the ash receiving member 4. That is, the stove 1 prototyped at an overseas factory may have dimensional differences in details, differences in processing methods, deformation, etc., but nevertheless, the effect of height adjustment of the ash receiving member 4 can be confirmed. It was.

In the above description, the rooster 23 is provided in the first bottom plate 20 of the main body 2. However, any member may be used as long as it has a hole 22 through which air can pass, and can be replaced with, for example, punching metal.
Further, although the receiving piece 6 is provided on the main body 2 and the contact piece 50 is provided on the ash receiving member 4, the receiving piece 6 may be provided on the ash receiving member 4 and the contact piece 50 may be provided on the main body 2.

  The stove for a barbecue according to the present invention is useful when applied to a stove capable of adjusting the thermal power of solid fuel.
