AI Technical Summary

Technical Problem

Existing fire pits are prone to tipping over when burning solid fuels like wood, as the stacked fuels can collapse during combustion, leading to scattered contents and instability.

Method used

A fire pit design featuring a cylinder with protruding objects, a bowl, and a porous bowl, where the cylinder and bowl are arranged to prevent tipping, even if the fuel collapses during burning.

Benefits of technology

The design effectively prevents the fire pit from tipping over, even when the fuel collapses, maintaining stability and containing the contents during combustion.

Abstract

When burning solid fuel like wood in a fire pit, it burns well if the gaps between the fuels are appropriately opened and stacked, but as a result of burning, the stacked fuels may collapse, causing the fire pit to tip over and the contents to scatter. Even if the fuel collapses during combustion in the fire pit, a fire pit that is difficult to tip over is proposed. 【Solution means】The fire pit is composed of a cylinder provided with a plurality of protruding objects, a bowl, and a porous bowl. The cylinder is placed with the protruding objects facing upward, the bowl is placed inside the cylinder, and the porous bowl is placed inside the bowl for use.

Summary of the Invention

Problems to be Solved by the Invention

[0005] When burning solid fuel such as wood in a fire pit, it burns well if the gaps between the fuels are appropriately opened and stacked, but as a result of burning, the stacked fuels may collapse, causing the fire pit to fall over and the contents to scatter. A fire pit that is difficult to fall over even if the fuel collapses during combustion is proposed.

Means for Solving the Problems

[0006] A fire pit composed of a cylinder provided with a plurality of protruding objects, a bowl, and a porous bowl, where the cylinder is placed with the protruding objects facing upward, the bowl is placed inside the cylinder, and the porous bowl is placed inside the bowl for use.

Effects of the Invention

[0007] When burning wood using the brazier of the present invention, stack firewood on the crossbeam, light it, then place heavy fuel such as a stump on it. Even if the crossbeam part burns and the fuel collapses, the brazier can be prevented from tipping over.

Modes for Carrying Out the Invention

[0009] The bowl and the porous bowl of the brazier of the present invention can use commercially available ones for cooking, but are not limited to them. The cylinder with a protruding part of the brazier of the present invention can be made using commercially available metal fittings and screws, but is not limited to their materials and manufacturing methods.

Examples

[0010] A cylinder with one side being 31 cm and a height of 2 cm was made using a 2 cm wide and 30 cm long stainless steel stay and a 2 cm wide and 5 cm side stainless steel hinge. A protruding part with a height of 7.5 cm was provided at the center of each side of the cylinder using a 2 cm wide and 10 cm long stainless steel stay to make an anti-tipping device for the brazier of the present invention. A 28 cm diameter and 10 cm deep stainless steel bowl was placed inside this anti-tipping device, and a 28 cm diameter and 10 cm deep stainless steel porous bowl was placed inside this bowl to make the brazier of the present invention. After stacking firewood on the edge of the stainless steel porous bowl on the crossbeam and lighting it, when a stump was placed on the crossbeam, the stump also started to burn. When the combustion in the central part of the firewood on the crossbeam advanced and the stump collapsed, it was confirmed that the brazier did not tip over.

Industrial Applicability

[0011] The brazier of the present invention can be expected to meet the needs at home, camping sites, etc.

Claims

[Claim 1] This fire pit is made up of a cylinder with a plurality of protrusions, a bowl, and a porous bowl, and is used by placing the cylinder with the protrusions facing upward, placing the bowl in the cylinder, and placing the porous bowl in the bowl.
