Description

The present invention is a combustion aid with a combustion air guide vane installed on the outer periphery of a flame or a combustible material.

Combustion air guide vane for gas stove (utility model registration number 3098847)

An existing combustion air guide vane for a gas stove cuts the lower part of the combustion cylinder (1) vertically and bends it inside the combustion cylinder (1) to produce the combustion air guide vane (2). A part of the combustion air taken into the combustion cylinder (1) is blown up by the combustion air guide vanes (2) and rises at an unnecessarily high speed, after colliding with the outer flame part of the flame (3) that has finished combustion. Released into the atmosphere. Therefore, the energy of combustion air is lost and the improvement of combustion efficiency is prevented. Further, the combustion air guide vane (2) supporting the combustion cylinder (1) is close to the flame (3) and becomes a high temperature, and if used for the high temperature flame (3), the life of the product is also shortened.

Further, when the combustion air guide vane (2) is manufactured from a flat plate, it is necessary to bend the combustion air guide vane (2) after making a vertical cut in the flat plate to form the combustion cylinder (1) into a cylindrical shape. .

Further, since the combustion cylinder (1) is finished in a cylindrical shape to make a product, it is not possible to superimpose, and a large volume is required when the product is transported.

The present invention is produced by bending the combustion air guide vane (2) to the outside of the combustion cylinder (1) and swirling the combustion air with the combustion air guide vane (2) outside the combustion cylinder (1). The combustion cylinder (1) eliminates the combustion air blowing up, reduces the energy loss of the combustion air, and uses the energy for the collision with the flame (3) unburned part of the internal flame, the middle flame, etc. Improve combustion efficiency. The combustion air guide vane (2) that supports the combustion cylinder (1) is located outside the combustion cylinder (1) and is farther from the flame (3) and has a lower temperature, so it can be used for a higher temperature flame (3) The service life will be longer.

Further, when the combustion air guide vane (2) is obliquely cut into the flat plate and the combustion cylinder (1) is formed into a cylindrical shape, the combustion air guide vane (2) opens to the outside by itself and combustion air is used. The work of bending the guide blade (2) is omitted. The intake amount and the turning force of the combustion air are adjusted by the depth and angle at which the combustion air guide vane (2) is cut.

FIG.

Is cut in a straight line, but may be cut in a parabolic shape that curves upward.

Further, the top of the combustion cylinder (1) is finished in the shape of a truncated cone to enable overlapping, and the volume of the product is reduced during transportation.

The invention's effect

Bending the combustion air guide vane (2) to the outside of the combustion cylinder (1) and manufacturing the combustion air guide vane (2) in the combustion cylinder (1) eliminates the blowing up of the combustion air. ), The residence time of the combustion air can be increased, the temperature rise can be increased, and the combustion air can be used for the collision of the flame (3) with the unburned portion. The flame (3) is evenly agitated and burned by the swirling of the combustion air, heating the pan evenly and improving the thermal efficiency. As a result of a simple test comparing the boiling time of the same amount of water for comparison between the case where the combustion auxiliary tool with the combustion air guide vane of the present invention is used and the case where it is not used, the existing combustion air guide for a gas stove The boiling time reduction rate of the blade exceeded 11.6%, and the boiling time was reduced by 13%.
Further, since the combustion air guide vane (2) is farther from the flame (3) and has a low temperature, it can be used for a higher-temperature flame (3) such as an oil stove and an outdoor stove, and its application is expanded. The product life is also prolonged.

The process of bending the combustion air guide vane (2) performed after forming the combustion cylinder (1) is omitted by cutting the combustion air guide vane (2) into the flat plate and processing it. Further, the intake amount and the turning force of the combustion air can be adjusted by adjusting the depth and angle of cutting of the combustion air guide vane (2).

The combustion cylinder (1) has a truncated cone shape and is finished into a product, thereby enabling overlapping and reducing the volume during product conveyance.

The present invention is installed on the outer periphery of a flame (3) or a combustible material, recovers ambient warm air, and uses it as combustion air to improve thermal efficiency. It is intended to improve the drawbacks of the existing combustion air guide vanes for gas stoves, further improve the combustion efficiency, expand applications, shorten the manufacturing process, and reduce the volume during product transportation.

Since the conventional combustion air guide vanes for gas stoves are manufactured by bending the combustion air guide vanes (2) inward, the combustion air guide vanes (2) blow up the combustion air in the combustion cylinder (1) to finish the combustion. The energy of the combustion air is wasted by colliding with the outer flame portion of the flame (3). By cutting the combustion air guide vane (2) and bending it to the outside of the combustion cylinder (1), the combustion air produces a turning force by the combustion air guide vane (2) outside the combustion cylinder (1), and the combustion cylinder (1) The combustion air guide vane (2), which is sent to the inside and causes energy loss, is not blown up, and the turning force inside the combustion cylinder (1) is increased. Further, the combustion air is guided slightly downward by the external combustion air guide vanes (2) during intake, so that the rising speed is suppressed. As a result, the combustion air stays in the combustion cylinder (1) for a long time, the rising temperature becomes higher, and the combustion air collides with the unburned portion of the flame (3) such as the inner flame and the outer flame while swirling vigorously. And the unburned part of the flame (3) are accelerated and burned. Moreover, since the combustion air guide vane (2) supporting the weight of the combustion cylinder (1) becomes a low temperature far from the flame (3), it can be used for a higher temperature flame (3), and the use of the product can be improved. Spreads and prolongs product life.

Further, when the combustion air guide blade (2) is manufactured from a flat plate, if the combustion air guide blade (2) is cut vertically, it is necessary to bend the blade after forming the combustion cylinder (1). When the combustion air guide vane (2) is cut obliquely and manufactured, the combustion air guide vane (2) opens to the outside by itself when the combustion cylinder (1) is formed into a cylindrical shape. The longer the depth at which the combustion air guide vane (2) is cut, the larger the combustion air guide vane (2) will open, and the greater the amount of intake of combustion air will be, and the cut angle (the angle of the straight line connecting the cut port and the cut end) will be horizontal. The closer to, the longer the combustion air guide vane (2) and the greater the turning force of the combustion air. When the cutting depth and angle of the combustion air guide vane (2) are adjusted so that the combustion air guide vane (2) has a constant opening and length after forming the combustion tube (1), the combustion cylinder (1 It is possible to omit the work of bending the combustion air guide vanes (2) performed after the molding. Since the tip of the combustion air guide vane (2) has an acute angle, it is made round so as not to damage the human body during handling.

Further, the combustion cylinder (1) is finished with a truncated cone shape by making the bottom part wider than the top part by a press or the like. As a result, the products can be overlapped, and the volume during product conveyance is reduced.

The present invention can be used by attaching it between a commercially available stove Gotoku (4) and a saucer (5), or by incorporating it as a part in a new stove or stove, or by using a high strength material such as cast iron. , Secure a gap for the container (pan) support part and exhaust / fuel (firewood, etc.) inlet at the top, and place it on the ground outdoors to use as a stove. Since it is preheated by the exhaust, it becomes a stove for camping characterized in that it is easy to ignite, the fire is quick, the blowing of excess wind is prevented, and the combustion efficiency is improved. In addition, for the purpose of shortening the burning time of incense sticks when there are many funerals, the combustion aid with a combustion air guide vane of the present invention is made small and used in an incense furnace to promote burning of incense sticks and smoke. It becomes a combustion aid for burning incense that reduces the occurrence of odor.
