Description

  The present invention relates to a furnace for a charcoal stove, and is intended to facilitate ignition, combustion, and extinguishing of charcoal in the stove.

A conventional charcoal stove is a method in which charcoal is directly put into the furnace and ignited and burned with an ignition material or a burner, and air is taken in from below to increase the combustion range, for example (Registered Utility Model No. 3031595) . When extinguishing a fire, the main method is to take the charcoal outside and put it in a charcoal extinguisher or put water on it, or to put the water on the stove itself and extinguish it.
Registered Utility Model No. 3031595

Problems to be solved by the invention

  1 Accumulation of charcoal to facilitate ignition is difficult.

  2 Although there was a metal ignition container as one of the conventional ignition methods, the charcoal that entered the container after igniting with a gas burner ignites and burns better in the bottom, so when transferring to a stove furnace If you turn the charcoal and turn on the charcoal, the weakly ignited charcoal will come down, and the charcoal that has ignited well will come up. As a result, the top and bottom of the charcoal must be swapped again.

  3 If the cooking ingredients are small compared to the size of the stove furnace, the charcoal fire is collected in a small area, but it is difficult to stack the charcoal fires so as not to weaken the thermal power.

  4 As a method of extinguishing fire, take out charcoal fires one by one with a flame, put water in a charcoal extinguisher, turn the stove body upside down, put the charcoal fire outside and put water on it, water directly on the stove itself However, it is an object to solve inconveniences such as troublesome work, distortion of the stove body and rusting.

Means for solving the problem

  The invention of claim 1 for solving this problem uses a wire mesh or a porous metal plate (hereinafter collectively referred to as a porous metal plate) and has a ridge having an opening in the upper portion (hereinafter referred to as 籠). A small coal receiving metal plate 2 having a vent 3 at the bottom of 1 is dropped so as to maintain a distance 4 from the bottom of the container. It is a furnace for charcoal stoves (hereinafter collectively referred to as a furnace) having the above-described configuration.

The invention's effect

By using the furnace rod of the present invention for an existing stove, it becomes easy to pile up the charcoal at the time of ignition of the charcoal, and it is not necessary to reload the charcoal when moving it to the stove. In addition, there is no need to be bothered by the accumulation and removal of charcoal when adjusting the thermal power. In addition, the range of thermal power can be adjusted without weakening the thermal power by increasing or decreasing the number of furnaces.
When extinguishing the fire, the furnace rod is taken out of the stove and extinguished so that the deterioration of the stove body due to distortion and rust can be greatly delayed.

The case where the furnace furnace of this invention is used with the existing stove for charcoal fire is demonstrated.
Select charcoal that is designed to fit in the stove's furnace with room and put charcoal. Charcoal stacks are easy because they are in a state of being naturally stacked with a moderate space by the peripheral wall of the furnace.

Then heat it directly from below with a burner or burner hob.
As shown in FIG. 2, the charcoal 6 is ignited from the lower portion of the charcoal accumulated by the flame heat 8 that has passed through the vents of the bottom of the ridge 1 and the small charcoal receiving metal plate 2. Of course, there is no problem even with a method using an igniting agent, which is an ignition method generally used at present.

  Next, as shown in FIG. 3, a plurality of or a single unit is moved and installed in the furnace portion of the stove with a tool that can be safely grasped, such as a supporting rod 9 or heat-protecting gloves. Since no ignition container is used, there is no need to refill charcoal. While waiting for the fire to increase, put the grill on the stove opening and put the cooking ingredients.

Adjusting firepower is carried out in increase or decrease of charcoal in the furnace basket, but consideration for charcoal stacked removed by the circumferential wall of Rokago even when its is almost unnecessary. In addition, when multiple furnaces are installed, the range of the thermal power can be adjusted without decreasing the thermal power by increasing or decreasing the number of furnaces, and the work is easy.

  When extinguishing the fire, the firewood is taken out from the furnace in the stove with the support rod 9 or the firewood, and directly fired or submerged in the water. Almost unnecessary.

After that, you can wait for the fire extinguishing due to the spontaneous combustion of the small coal fire remaining in the furnace.
As shown in FIG. 2, the small coal receiving metal plate 2 in the cage has a structure in which portions other than the air holes 3 receive the small coal fire and ash. If the total amount of small charcoal fire left in the stove furnace after taking out the furnace for fire extinguishing is small, it can be extinguished naturally in a short time.

  However, when the fire extinguishing time may be somewhat longer or the lower ventilation performance may be somewhat deteriorated, the small coal receiving metal plate may not be provided.

Next, before explaining a new charcoal stove using this furnace with examples, the rationale underlying the present invention will be explained.

  It is a well-known fact that charcoal fire can increase firepower even in a small brazier surrounded by a peripheral wall as long as it is ignited, and it can maintain firepower only by fine ventilation between ash grains even when buried in ash. . The present invention is an application of the above fact.

FIG. 4 is an explanatory cross-sectional view when the furnace is used in a container having only an opening.
The furnace furnace having a ventilation function both in the periphery and in the lower part has a function of a stove itself. By providing an appropriate space between the container 14 having only the stored opening, the air is sufficiently ventilated. Can be supplied to the charcoal fire 13 to increase the thermal power.
Next, a charcoal stove using the characteristics of the above furnace is provided.

FIG. 5 is an example of a charcoal stove with a fire extinguishing function.

A flat cover 16 is used. A plurality of or a single charcoal fired furnace 10 is installed in the furnace. Used with the container opening.

As described above, the furnace furnace of the present invention does not require a vent hole for increasing the fire power other than the opening in order to expand natural combustion. Accordingly, when the fire is extinguished after use, only by placing the flat plate lid 16 in close contact with the edge plate at the upper part of the opening, air-tightness in which air is not supplied to the charcoal inside can be obtained, and the charcoal with a fire extinguishing function can be easily extinguished. Provide a stove.

  As shown in FIG. 6, it is also possible to obtain a stronger airtightness by providing a non-flammable and elastic contact plate 21 around the edge of the lid. In this case, the edge plate 17 may be omitted.

FIG. 7 shows another example of the charcoal stove with the fire extinguishing function.
A groove 22 is provided around the edge of the opening of the stove container. A peripheral edge plate 23 is provided around the outer periphery of the lid. Use a charcoal stove as in Example 1.
When the fire is extinguished, as shown in FIG. 8, the lid is put into a shape in which the peripheral plate 23 is fitted in the groove 22 provided around the stove, and water 25 is poured into the groove 22. As a result, there is provided a charcoal stove with a fire extinguishing function that provides strong airtightness in the stove, shortening the fire extinguishing time and ensuring certainty.

FIG. 9 shows an edged cutout lid 26 as another example of the lid of the stove.
During fire extinguishing, water is poured into the groove to generate water vapor inside the stove, increasing the atmospheric pressure. In order to allow the atmospheric pressure to escape to the outside, an internal pressure relief notch 28 may be provided at a location that is below the draft line 27 of the edge plate around the lid during water injection.
The stove lids of Examples 1 and 2 can also be used as a baked iron plate. After use, the stove lid is used as a storage container using a lid stopper (for example, the locking bracket 19 locking piece 20 in the figure). May be.
