Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of stove equipment, and more particularly to a windproof stove. Background Art
[0002] Existing portable small stoves usually use solid alcohol stoves or currently more popular gas stoves supplied by small gas cylinders. Traditional solid alcohol stoves are inexpensive, easy to use, and have a simple and reliable structure. The portable gas stove supplied by a small gas cylinder has a safe fuel supply, but gas stoves usually use cast metal, which is heavy, inconvenient to carry, and more costly.
[0003] Except for improving the fuel supply method, the gas stove has not been optimized in terms of the stove body design. The traditional household gas stove structure it adopts cannot meet the requirements for outdoor use because the biggest problem faced by outdoor stoves is the windproof problem.
[0004] In outdoor / wild use environments, the flame of the gas stove is more concentrated than that of the traditional alcohol stove, with higher thermal efficiency and better wind resistance. However, under the disturbing effect of the wind, a large amount of heat energy will also escape from the surroundings, wasting precious energy and being unfavorable for more efficient use by camping or hiking users.
[0005] In view of the above requirements for cost and windproof, people need a stove that is more effective in windproof and energy-saving. Summary of the Invention

DETAILED DESCRIPTION
[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with embodiments.
[0041] A windproof stove, comprising a basin-shaped stove shell 1 made of metal, and a heat-insulating cotton material is coated on the inner wall of the stove shell 1. An exhaust hole 5 is opened at the upper edge of the side wall of the stove shell 1 for discharging combustion waste gas. An air inlet hole 6 is also opened on the side wall of the stove shell 1 below the exhaust hole 5. The air flow entering through this hole is a low-temperature air flow and will not interfere with the hot air flow discharged above it. Since the exhaust hole 5 and the air inlet hole 6 are on the same side, even on the windward side, the situation where the air flow quickly penetrates through the stove body will not occur, reducing the heat loss rate.
[0042] A combustion stove 3 and a support ring 2 are arranged in the stove shell 1. The upper surface of the combustion stove 3 is provided with a concave structure for accommodating combustion materials. The support ring 2 is used to support the pot stove 8 cooperating with the windproof stove. The support ring 2 is composed of two semi-rings combined into a complete ring. For the convenience of description, the semi-rings separated on the left and right sides are respectively named the first semi-ring 21 and the second semi-ring 22, and the two semi-rings surround the periphery of the combustion stove. When the first semi-ring 21 and the second semi-ring 22 are closest to each other, there is still a gap at their ends for discharging combustion waste gas through this gap.
[0043] There is a gap between the support ring 2 composed of the first semi-ring 21 and the second semi-ring 22 and the combustion stove 3. It is used for the entry of combustion-supporting gases such as air. The combustion-supporting gases enter the combustion stove 3 through a number of air exchange holes 7 provided at the upper edge of the side wall of the combustion stove 3 for combustion support, and then escape through other air exchange holes 7. The escaping hot air bypasses the space between the combustion stove 3 and the support ring 2, continues to heat the pot stove, then flows along the bottom surface of the pot stove through the gap left between the first semi-ring 21 and the second semi-ring 22 into the space outside the support ring, continues to heat the pot stove, and finally enters the external environment through the exhaust hole 5.
[0044] In order to achieve the effect of delaying the dissipation of heat energy in the above three spaces, each space needs to be relatively airtight to prevent the air flow from directly penetrating and taking away heat. For this purpose, the upper edge of the combustion stove 3, the upper surface of the support ring 2, and the upper edge of the stove shell 1 all need to fit with the pot stove 8.
[0045] In order to prevent the gap between the combustion stove 3 and the support ring 2 from being too large, the edges of the first semi-ring 21 and the second semi-ring 22 close to the combustion stove 3 are bent downward by a certain distance until they are basically level with the bottom surface of the combustion stove 3, and then extend towards the combustion stove 3. The structure extending inward forms the bottom surface of the space formed between the combustion stove 3 and the support ring 2, which is beneficial to maintaining the relative sealing of this space environment and has an obvious effect on temporarily storing heat energy.
[0046] In this embodiment, the burner 3 is movably installed in the furnace shell 1, so that the burner 3 can move up and down relative to the furnace shell 1. In order to control the up and down movement of the burner 3, the burner 3 is supported by an elastic material. The first half ring 21 and the second half ring 22 that make up the support ring 2 are respectively hinged and installed on the left and right sides inside the furnace shell 1. The burner 3 is hinged with two connecting rods 4. When the burner 3 moves up and down, the first half ring 21 and the second half ring 22 corresponding to it are respectively driven by the connecting rods 4 as push hands to realize the opening and closing of the support ring 2.
[0047] A more specific installation scheme is as follows:
[0048] The burner 3 is made of metal, and two guide rods 9 are welded to the bottom. The other ends of the guide rods 9 are free ends, and the free ends are respectively movably inserted into the corresponding guide sleeves 10. The guide sleeves 10 are fixed to the bottom surface of the furnace shell 1 by welding. A compression spring 11 is respectively embedded in the guide sleeve 10. One end of the compression spring 11 abuts against the bottom surface of the furnace shell 1, and the other end respectively abuts against the corresponding guide rod 9 to support the reset of the guide rod 9. When the cooker is seated on the burner 3, the two compression springs 11 are compressed and store energy.
[0049] Two rotating shafts 13 are fixedly connected to the inner wall of the furnace shell 1. The ends of the rotating shafts 13 are supported by the side walls of the furnace shell 1 at the corresponding positions. The support method is welding and fixing support, or for the convenience of disassembly, a groove structure arranged on the side wall of the furnace shell 1 is used for overlapping support. The bottom parts of the first half ring 21 and the second half ring 22 are respectively fixedly welded with a vertically downward extending part 12. The above two extending parts 12 are both strip structures, and hinge holes 17 that are respectively fitted on the corresponding rotating shafts 13 are provided at the lower ends of the extending parts 12.
[0050] First connection ends 14 also respectively extend from the side parts of the extending parts 12. Correspondingly, the middle parts of the guide rods 9 are respectively bifurcated to form second connection ends 15. The first connection ends 14 and the second connection ends 15 are correspondingly connected by the connecting rods 4, and the connection method is hinged, so that the first half ring 21 and the second half ring 22 can be flipped by means of the connecting rods 4 during the lifting process of the guide rods 9.
[0051] In order to realize the flipping of the upper structures of the first half ring 21 and the second half ring 22 in the form of being pushed outwards by the connecting rods 4, naturally, the rotating shaft 13 should be located below the first connection end 14, that is, the rotation center is located below the rotating part.
[0052] During the implementation process, the cooking stove presses on the combustion stove 3, moving the guide rod 9 downward relative to the guide sleeve 10 and squeezing the compression spring 11 to store energy. During the downward movement of the guide rod 9, the connecting rod 4 acts as a pull rod to pull the first half-ring 21 and the second half-ring 22 from the open state towards the combustion stove 3. Eventually, the ends of the first half-ring 21 and the second half-ring 22 are joined together to form a support ring, which fits against the bottom surface of the cooking stove. The support ring 2 and the combustion stove 3 form a second heat storage and heating space. At the same time, through pre-designed dimensions, the bottom surface of the cooking stove also fits against the upper edge of the furnace shell to form a third heat storage and heating.
[0053] After removing the cooking stove, the compression spring 11 resets and performs the above actions in reverse. The connecting rod 4 acts as a push rod to push the first half-ring 21 and the second half-ring 22 away from the combustion stove 3 from the buckled state, and the combustion stove 3 rises, facilitating operations such as filling and cleaning the combustion stove 3 and avoiding being scalded by the support ring 2 close to the combustion stove 3.
[0054] In another embodiment, the compression spring 11 can be replaced with an incompressible cylinder. At this time, the first half-ring 21 and the second half-ring 22 always remain in the open state, and the flipped-open first half-ring 21 and second half-ring 22 form additional concave structures between their respective inner edges 16 and the adjacent side walls. Each concave structure can also be used as a combustion stove, which can expand the heating area in an environment with low wind protection requirements, adapt to different heating needs, and improve the flexibility of equipment use.
[0055] In another embodiment, considering the heat preservation and insulation requirements of the combustion stove 3, a ceramic combustion stove 3 can also be used. At this time, the guide rod 9 at its bottom adopts an integral molding scheme or a hole-shaft transition insertion and fitting scheme.
