Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charcoal stove capable of easily cooking using a charcoal fire even at home.

[0002]

2. Description of the Related Art In recent years, gas cookers,
Electric stoves, gas ovens, microwave ovens, and the like have been increasingly used. On the other hand, charcoal grilling is known to have a uniform thermal power and a far-infrared effect, so that when cooking grilled food such as meat or vegetables, the fire will pass through to the inside and the grilling will be clear and clear. Recently, with the outdoor boom, charcoal fire has been actively used for outdoor barbecues and the like.

[0003] By the way, the conventional seven-wheel is known as a form of using charcoal grilling in a kitchen, but in the case of seven-wheel, it is troublesome to start charcoal and transfer charcoal to a fireplace for extinguishing fire. There is a problem that it is not easy to use because there are many dangerous works. Therefore, a charcoal stove that can be placed on a household gas stove and cooked easily has been proposed (Japanese Patent Laid-Open No. 10-19259). This charcoal stove accommodates charcoal on a roster inside a cylindrical main body part whose upper and lower ends are open, puts it on a gas stove, and ignites the charcoal. It is placed on the bottom lid for cooking. An openable / closable vent for introducing air is formed in the lower side surface of the main body. When the cooking is completed, the openable / closable vent is closed, and the fire is extinguished by covering the upper lid.

[0004]

However, in the above-mentioned conventional charcoal stove, a sliding or hinged door system is used as an openable / closable vent. When the ventilation opening is a sliding door type, it is difficult to completely seal the inside of the tubular main body during fire extinguishing because a certain gap is required for sliding. If the inside is not completely sealed when extinguishing the fire, it will take time to extinguish the charcoal fire, and the remaining unburnt charcoal will become ash instead of remaining as extinguishing charcoal, causing a problem that extra charcoal will be consumed. . Further, in the case of the hinged door type, there is a problem that it is difficult to adjust the opening of the ventilation opening.

The present invention has been made in view of the above points, and provides a charcoal stove capable of easily adjusting the opening of a ventilation port, shortening a fire extinguishing time when extinguishing a fire, and suppressing a consumption of charcoal. The purpose is to do.

[0006]

According to the present invention, there is provided a charcoal stove according to the present invention, wherein a charcoal accommodating portion for accommodating charcoal is formed therein, and a cylindrical main body having upper and lower ends opened; While receiving the ash falling from the main body portion, a gap for air introduction is formed between the lower end portion of the main body portion and the air introduction portion that gradually or continuously expands from the close contact state according to the rotational position of the main body portion. A lower lid having an upper end formed as described above, and an upper lid provided to close the upper end of the main body, and a portion between the lower end of the main body and the upper end of the lower lid at the time of ignition. A suitable gap is formed according to the thermal power, and at the time of fire extinguishing, the lower end of the main body and the upper end of the lower lid are brought into close contact with each other and the upper end of the main body is closed with an upper lid. It is characterized by.

According to the present invention, a gap for air introduction is formed between the lower end of the tubular main body for accommodating charcoal and the lower lid and gradually or continuously expanded from the close contact state. Since the structure is such that the lower end of the main body and the upper end of the lower lid are in close contact with each other, it is easy to adjust the heating power by adjusting the gap, and the degree of internal sealing at the time of fire extinguishing is also high. The fire is extinguished, and the remaining unburnt charcoal remains mostly as fire charcoal. Thereby, the consumption of charcoal is suppressed, and a very economical charcoal stove can be provided.

The lower end of the main body and the upper end of the lower lid may be, for example, a system in which each step formed in a step shape is shifted one step at a time. If each step is inclined slightly, for example, the positioning performance of the main body in the rotational direction with respect to the lower lid is increased, and the adhesion between the two is also increased. Even if each step is formed in an arc shape, the positioning of the main body with respect to the lower lid in the rotational direction is firmly performed.

Further, according to the present invention, since air can be introduced from a plurality of directions around the main body, there is an advantage that air can be uniformly introduced into the inside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view showing a fire pot type charcoal stove according to one embodiment of the present invention. This charcoal stove is basically composed of a cylindrical main body 1, a lower lid 2 and an upper lid 3.

FIG. 2 is a longitudinal sectional view of the charcoal stove. The body part 1 is open at the upper and lower ends, and at a position slightly above the lower end part, a rostral 4 having a net-like, lattice-like, or many holes is mounted in such a manner as to divide the internal cylindrical space into upper and lower parts. Things. Charcoal 5 on this rostrum 4
Is accommodated. A plurality of protrusions 7 are provided on the upper edge 6 of the main body 1 so that the inside of the main body 1 is not sealed when an iron plate or the like is placed.
Are formed. Handles 8 are attached to opposing side surfaces of the main body 1.

The lower end of the main body 1 has an inner fitting portion 11 having a diameter smaller than that of the main body 1 and protruding downward.
An upper fitting portion 12 is formed on an annular edge extending from the upper end of the main body 1 to the outer periphery of the main body portion 1, and has a step-shaped step portion fitted with the lower lid 2. The inner fitting portion 11 has an air introduction hole 13 serving as a flow path for air communicating between the inside and the outside.
Are formed at predetermined intervals in the circumferential direction. The lower lid 2
A lower fitting portion 14 having a dish-like shape capable of storing ash therein, and having a stepped step formed on the upper end annular edge of the upper fitting portion 12 of the main body 1 to be fitted in the vertical direction. Is formed. In addition, the upper cover 3 holds the main unit 1 when the stove is extinguished.
And is used to seal the upper end opening of the main body 1.

The main body 1, the lower cover 2 and the upper cover 3
The whole may be formed of a firebrick or the like, or the inside and the outside may be formed of a metal such as stainless steel and a heat insulating material such as rock wool may be interposed therebetween.

Next, how to use the charcoal stove will be described. First, the charcoal 5 as a fuel is put on the roster 4 inside the main body 1, only the main body 1 is placed on a gas stove (not shown), and the gas stove is ignited. Ignite. When the charcoal 5 is ignited, the main body 1 is placed on the lower lid 2 to start cooking. At this time, since the fire of the gas stove can be wrapped by the inner fitting portion 11 protruding below the main body portion 1, the upper fitting portion 12
Can be prevented from being deformed by heat. In this regard, in the conventional charcoal stove described above, it is conceivable that the openable ventilation port is deformed by heat when igniting charcoal on the gas range.

The heating power is adjusted by adjusting the gap between the main body 1 and the lower lid 2. That is, the charcoal stove is fitted with the fitting portion 1
By changing the mutual circumferential position of 2,14,
The gap between them can be adjusted. As shown in the plan view of FIG. 3, the fitting portions 12 and 14
The height of each of the two divided steps is changed stepwise, and the three steps are repeated as one cycle, and the vertical highest surface is I, the next highest surface is II, and the lowest surface is II. Face
4A, the planes I, II, and III of the upper fitting portion 12 and the surfaces I, II, and III of the lower fitting portion 14 are parallel to each other, as shown in a development view from the side in FIG. When the main body 1 is placed on the lower lid 2 so as to face each other, the main body 1 and the lower lid 2 are in close contact with each other, but as shown in FIG. When the mating portion 12 is shifted to the right by exactly one step with respect to the lower mating portion 14, a hatched line between the surface III of the upper mating portion 12 and the surface I of the lower mating portion 14 in the figure. Is formed. Further, as shown in FIG.
2 is shifted one step further to the right with respect to the lower fitting portion 14, the surfaces III and II of the upper fitting portion 12 and the surface I of the lower fitting portion 14
A gap G indicated by oblique lines in the figure is formed between I and I. When the gap G is formed between the fitting portions 12 and 14 as described above,
As shown in FIG. 5, combustion air is introduced into the stove through the gap G and the air introduction hole 13 formed in the inner fitting portion 11, and the heating power is adjusted according to the amount of the introduced air. Will be done. The amount of air introduced depends on the size of the gap G.

The outer diameter of the inner fitting portion 11 is made slightly smaller than the inner diameter of the lower cover 2, and the difference in size is reduced by the fitting portions 12, 14.
If it is set to be smaller than the fitting allowance of FIG.
In any of the states (a) to (c), the main body 1 does not come off the lower lid 2. In addition, in the state of FIGS. 4A and 4B, since the position is regulated also on the side surface of each step of the fitting portion, the main body 1 does not shift with respect to the lower lid 2 in the radial direction. If the main body 1 is displaced with respect to the lower lid 2, this is the case in FIG. 4C, and if necessary, the upper fitting 1
A restriction plate or the like (not shown) may be projected downward from the inner peripheral side of the lower cover 2 and brought into contact with the inner peripheral surface of the lower cover 2 to prevent radial displacement.

In cooking, if water is contained in the lower lid 2 and functions as a water dish, moisture evaporates and the thermal power of the charcoal increases, and the charcoal lasts longer. When the cooking is finished and this charcoal stove is extinguished, the relationship between the main body 1 and the lower lid 2 is brought into a completely adhered state as shown in FIG. Then, by putting the upper lid 3 on the main body 1, the inside of the stove is completely sealed, and the same function as the conventional fire jar can be obtained, so that the fire can be quickly extinguished.

In order to move the charcoal stove to another place in an ignited state, for example, a carrying member 21 as shown in FIG. 6 may be used. The carrying member 21 includes a lower lid case 22 that accommodates the lower lid 2, and a handle 23 that extends upward from an opposing side surface of the lower lid case 22.
And connecting rings 24 and 25 extending annularly along the outer peripheral surface of the main body 1 that connects the handles 23, and legs 26 provided on the lower surface of the lower lid case 21. FIG. 2 also shows a state in which the main body 1 and the lower lid 2 are housed in the carrying member 21. As shown in the figure, the upper end of the handle 23 is located below the handle 8 of the main body 1, and to lift the main body 1 together with the lower lid 2, the handle 2
You only need to have 3.

FIG. 7 shows a further improved embodiment. In this embodiment, a handle 32 of the carrying member 31 is formed in a cylindrical shape, and a slider 33 is accommodated inside the handle so as to be slidable in the vertical direction. And slider 3
Numeral 3 is configured to engage with the distal end of the lever 34 at its lower end, and to slide in the vertical direction by the principle of leverage in response to the vertical operation of the lever 34. A handle 35 is attached to a side surface of the lower cover 2.

When the lever 34 is lowered, the slider 33 protrudes upward as indicated by the arrow in the drawing by the principle of leverage, and pushes up the handle 8 of the main body 1 from below. The whole is lifted up as shown by the dotted line. In this state, since the lower cover 2 is in a free state, the handle 3
5 is rotated in a rotation direction as indicated by an arrow in the figure to position it at a desired position. Then, when the lever 34 is returned to the original position, the main body 1 and the lower cover 2 are fitted at a desired position. According to this embodiment, since the lower lid 2 is rotated without rotating the main body 1, there is an advantage that the gap adjustment for adjusting the heating power is simplified.

The present invention is not limited to the embodiment described above. In the above embodiment, the main body 1 and the lower lid 2
Although the mating surface with is formed by a flat step-shaped step portion, for example, as shown in FIG. 8, the surface of each step portion may be formed in an arc shape protruding downward or upward. When formed in this manner, lateral displacement is less likely to occur than in the previous example, so that the positioning accuracy of the main body 1 and the lower lid 2 in the radial and circumferential directions is increased, and the adhesion is further increased.

Further, as shown in FIG. 9, a predetermined inclination may be given to the fitting surface between the main body 1 and the lower cover 2.
In this case, since a force in the direction in which the main body 1 and the lower lid 2 come into close contact with each other not only on the upper and lower fitting surfaces but also on the left and right fitting surfaces,
The positioning accuracy of both is further improved.

In the above description, an example in which the number of stages is three has been described. However, if the number of stages is further increased, it goes without saying that finer adjustment is possible. Also, the main body 1 and the lower lid 2 are
For example, if the shape is a gentle wave as shown in FIG. 10 or if the shape is a gentle slope in the range of 180 ° as shown in FIG. Since the magnitude of G can be continuously changed, more subtle adjustment of the heating power becomes possible.

FIG. 12 is a view showing an example in which the charcoal stove 41 according to the present invention is incorporated in a gas stove. As in this example, one stove unit 43 of the gas stove 42
And the charcoal stove 41 can be exchanged,
Cooking with the charcoal stove 41 becomes possible with the same feeling as the gas stove 42 at home.
