Description
- (a) Field of the Invention
- The present invention relates to a windproof stove, and more particularly to a windproof stove able to achieve effectiveness of resisting lateral wind pressure.
- (b) Description of the Prior Art
- With reference to stove units that use flames to heat and cause combustion, sufficient air must be available to satisfy the requirements to cause a vigorous oxidation reaction. However, because an air mixture of specific ratio must be supplied, thus, the combustion assembly of the stove units must be configured with an emerging or protruding upper end opening. In general, if gas cooking devices or liquid fuel stove units, such as spirit stoves, gas stoves, and the like, are used in a location where the surrounding airflow is relatively strong, then lateral wind pressure inevitably blows out the flames of the fire hole or disturbs operating line of the flames.
- Referring to
FIG. 1 , which shows heating operation of apot 100 disposed on top of a stove unit 1, and a ring-shaped plate grid 10 is constructed at a periphery of the stove unit 1 in order to resist lateral airflow. However, such a structure is inconvenient to carry, and a bottom portion of theplate grid 10 intercepts and seals off airflow from entering the stove unit 1, thereby disabling the stove unit 1 from ensuring effective combustion. Even if an air port is defined in a lower portion of theplate grid 10, then air will pass directly through the air port and attack flames of the stove unit 1. - Accordingly, a primary objective of the present invention is to provide a windproof stove that particularly uses an encircling ring configured at position of the combustion chamber relative to an upper end surface of a combustion device to serve as a lateral containment. Moreover, an annular air port is configured between the encircling ring and the combustion device, and is used to enable airflow to enter therethrough, thereby enabling the stove to obtain sufficient oxygen during the process of combustion.
- Another objective of the present invention is to provide the windproof stove with an upper and a lower encircling ring having diameters of different size to enable another annular air port to be formed by the interspace between the mutually sleeved upper and lower encircling rings, thereby providing sufficient oxygen to propagate substantially longer flames and contain flame tips.
- A third objective of the present invention is to provide the windproof stove that enables the encircling rings directly supported by support bars extending from foot rests, and mechanical force of the encircling rings enables assemblage of the foot rests.
- A fourth objective of the present invention is to provide the windproof stove that enables expansion of feet of a stove body, moreover, the stove body can be inverted for use thereof.
- A fifth objective of the present invention is to provide the windproof stove that enables height adjustment between the encircling rings and the joined support bars.
- A sixth objective of the present invention is to provide the windproof stove wherein end openings of the crossover of the encircling rings are respectively configured valve plates.
- To enable a further understanding of said objectives and the technological methods of the invention herein, brief description of the drawings is provided below followed by detailed description of the preferred embodiments.

FIG. 7 shows an application drawing of an inversion ofFIG. 6 according to the present invention. - Referring to
FIG. 2 , which shows the present invention primarily structured to comprise a plurality offoot rests 3 radially distributed in an encircling configuration to form astove body 2. An upper end of each of thefoot rests 3 is joined to agrate 31, and a lower end is joined to afoot 32. Interior of thestove body 2 is joined to anencircling ring 4 using a suspension method, and an interior of theencircling ring 4 enables disposition of acombustion device 22 therein. A lower end of the entire structure is provided with abase plate 21 that is able to support the weight of the entire structure and receive drips from cooking, thereby preventing staining a tabletop and enabling increasing area of contact with the ground, in addition to providing a thermal insulation effect. - An
annular air port 40 is formed between aperiphery 220 of thecombustion device 22 and an inner edge of theencircling ring 4. Flames are produced at anupper end surface 222 of thecombustion device 22, and theupper end surface 222 is positioned within the range of the height of theencircling ring 4 close to a center position, thereby enabling theencircling ring 4 to contain flames produced and resist lateral airflow. - Oxygen required for combustion enters through the
annular air port 40, bringing about an exchange at position of theupper end surface 222, whereupon vigorous oxidation takes place that produces thermal energy. Based on the configuration of the present invention, lateral strong wind is unable to directly attack the flames of thecombustion device 22, thereby enabling the flames to maintain normal thermal work. - Blocking of lateral airflow passing through the
encircling ring 4 forms a vertical angle resistance, and the surface of theencircling ring 4 disperses the pressure flow line of the lateral airflow. After disintegration velocity of flow is reduced, at which time a portion of the airflow enters through theannular air port 40, and a portion transversally brushes past between a bottom portion of thepot 100 and an end opening 42 of theencircling ring 4. The transversal airflow at the bottom portion of thepot 100 forms a back pressure effect within theencircling ring 4, thereby increasing recharge of rate of airflow at the bottom end of theannular air port 40. However, the rapid recharge of rate of airflow does not affect normal combustion at theupper end surface 222. By use of such basic conditions, the present invention is able to achieve implementation of a lateral windproof stove unit. - The
combustion device 22 is positioned interior of theencircling ring 4, thereby enabling theperiphery 220 of thecombustion device 22 to receive support fromsupport bars 321 extending from a bottom portion.

supportive bars 322 and theperiphery 220 of thecombustion device 22, thereby enabling adjusting vertical displacement thecombustion device 22 relative to distance to the bottom portion of thepot 100. - The
encircling ring 4 is fixedly supported by thesupport bars 321 extending from the bottom portion, or a movable fixed method can be used to support and fix position of theencircling ring 4, thereby enabling adjusting height of theencircling ring 4 to a horizontal L1 or L2 position, and thus realize functionality to alter distance relative to the bottom portion of thepot 100, or to enable use of thecombustion device 22 at different heights whereby adjustment of position of theupper end surface 222 is realized. - Relative position of the
end opening 42 of theencircling ring 4 primarily enables theencircling ring 4 to maintain an appropriate relative height position above theupper end surface 222 of thecombustion device 22, thereby enabling containment of flames and adjustment relative to the bottom portion of thepot 100. In order to accommodate different sizes of thepot 100, oblique height of thegrate 31 can be correspondingly changed to an appropriate difference in height position to the bottom portion of thepot 100. - Height H of the adjustable height of the
encircling ring 4 is according to that supported by length of thesupport bars 321. - When using the present invention outdoors or on the ground, then the
